technical field

The invention relates to the technical fields of a roller brush electric mop, a floor washing machine, a vacuum cleaner, a floor sweeper, etc., and specifically relates to a heating part, a roller brush and a cleaning device.

Background technique

In cleaning devices such as roller brush electric mops, floor washing machines, vacuum cleaners, and sweepers, the roller brush is one of the important technical means to improve cleaning performance. The general working principle of the roller brush is that the roller brush is in rotating contact with the surface to be cleaned , to clean the surface being cleaned by contact.

In order to improve the cleaning performance, it is proposed to spray cleaning liquid on the roller brush or before and after the roller brush. The cleaning liquid is such as detergent, water and other cleaning liquids. Cleaning performance. In addition, in order to further improve the cleaning performance, it is proposed to heat the cleaning liquid, that is, to use hot cleaning liquid to improve the cleaning performance. However, there are many different solutions for how to generate and supply the hot cleaning liquid. There are two types: one is to use electric heat or chemical energy to heat the cleaning liquid in the liquid storage tank, the liquid storage tank and the roller brush are connected by pipelines, and the cleaning liquid delivered is sprayed on the roller brush or To clean the surface, there are roughly two types of spraying on the roller brush, one is to spray on the upper side of the roller brush, and the other is to ooze from the cleaning part of the roller brush after diverting from the inner part of the roller brush. The distance is far, the energy consumption is high, and the response is slow. In addition, when it comes to the high-pressure and high-heat storage problem after the liquid storage tank is heated, how to ensure safety is a big problem; the other is a solution specially proposed by the applicant, that is, directly Heating in the roller brush, after the heated roller brush encounters the cleaning liquid, it indirectly heats the cleaning liquid to obtain a thermal cleaning effect. Compared with the original technology, this solution further shortens the heat transmission path, which is conducive to energy saving and improved response. Performance and safety issues are also better solved. In addition, the applicant does not need to install batteries at both ends of the barrel of the roller brush or in the barrel by setting up an electrical connection structure, but is powered by the power supply of the cleaning device. On the one hand, it increases On the other hand, it reduces the cost of replacing the rolling brush, so that the rolling brush proposed by the applicant can be practically applied in life, rather than theoretical. However, even if the applicant The proposed rolling brush has many advantages as above, and the applicant also hopes to further improve energy utilization efficiency and response performance, which is of great significance for reducing battery volume, reducing cost and improving practicability.

Therefore, the applicant continued in-depth research, and through the applicant's unremitting efforts, the applicant proposed a rolling brush, the rolling brush is provided with a heating part, and the heating part is in contact with and/or clearance fit with the outer periphery of the rotating cylinder. The heating part is used to heat the cleaning part of the rotating cylinder and/or the cleaning liquid supplied to the cleaning part. This structure can further improve energy utilization efficiency and response performance. In the aforementioned scheme, in order to further improve the heat utilization rate and reduce waste, The liquid outlet hole is very close to the cleaning part of the rotating cylinder, or even close to each other. For example, the liquid outlet hole is very close to the cleaning part of the rotating cylinder, so the cleaning liquid heated by the heating part can fall to the cleaning part in the shortest possible distance. In this way, the waste of heat before the cleaning liquid falls on the cleaning part can be reduced. For example, if the liquid outlet hole is very close to the cleaning part of the rotating cylinder, after the cleaning part is heated by the heating part, the output of the liquid outlet hole The cleaning liquid falls on the cleaning part as quickly as possible, so that the waste of heat caused by the time between the contact between the heated cleaning part and the cleaning liquid can be reduced, but it is hoped that the heated cleaning part Get in contact with the cleaning liquid as soon as possible, so that the cleaning liquid absorbs the heat on the cleaning part. It can be seen from the foregoing that no matter what the situation is, it is desirable that the liquid outlet is very close to the cleaning part of the rotating cylinder, or even close to each other. In this way, With the use of the rolling brush, the dirt may accumulate in the liquid outlet hole, thereby making the liquid outlet not smooth. Therefore, the applicant proposed a heating part through research to solve the aforementioned problems. In addition, he also proposed a A rolling brush and a cleaning device.

According to the aforementioned design, the structure of the heating element 5 can be conveniently arranged. On the other hand, through the heat conduction element 4, the heat can be transferred more comprehensively and simply. , so as to ensure the heating area of the cleaning part, and at the same time, it is beneficial to reduce the installation quantity of the heating element 5 and avoid adding too much weight.

It also includes a brush holder 1, the brush holder 1 is provided with a first opening 9 for detachably installing the rotating cylinder 3, and a heating part is arranged in the first opening 9. This design does not affect the replacement of the rotating cylinder 3, and after replacing the rotating cylinder 3, it is no longer necessary to adjust the distance between the heating part and the rotating cylinder 3, that is, it can be used directly after replacement, which greatly facilitates the use of users.

Preferably, as shown in Figures 1, 2, and 3, the brush holder 1 is detachably connected with an upper cover 2, and the heating part is located on the lower side of the upper cover 2. After the upper cover 2 is removed, the heating part can be seen. In addition, after the upper cover 2 is removed, the rotating cylinder 3 can also be removed in the up-down direction for cleaning or replacement, that is, the upper cover 2 serves as a position-limiting installation part of the rotating cylinder 3 at the same time. Such design can greatly facilitate the production and manufacture of the present invention, and at the same time facilitate the use of daily users.

A heating body of the heating part is provided on the side of the heating part that is used to stick to the outer circumference of the rotating cylinder 3 .

The heating body includes a continuous heat conduction element 4 arranged axially and a discontinuous heat conduction element 5 , the heat conduction element 4 is on the outside, and the heating element 5 is on the inside, and the heat conduction element 4 isolates the heat conduction element 5 from the rotating cylinder 3 . In this way, on the one hand, the setting and installation quantity of the heating element 5 are simplified, and on the other hand, the heat conducting element 4 isolates the heating element 5 from the rotating cylinder 3, which is beneficial to protect the heating element 5 and prolong the service life.

The heating part is continuously arranged along the axial direction of the rotating cylinder 3 . Such design can make the cleaning part evenly heated, which is beneficial to the cleaning performance.

It also includes a thermal insulation structure, which is used to transfer most of the heat generated by the heating part to the cleaning part. The thermal insulation structure is for example arranged on the heat insulation layer at the rear of the heating element 5 and around it, so that the heat of the heating element 5 is mainly transferred to the front side, that is, it is mainly transferred to the heat conducting element 4, and the heat conducting element 4 then transfers the heat to the cleaning part. This design is conducive to reducing waste and improving heat utilization.

In this example, the heat-conducting element 4 is arranged in an arc-shaped structure, that is, the heat-conducting element 4 is a concave arc-shaped plate. After this design, the concave arc-shaped plate matches the outer peripheral surface of the cleaning part, on the one hand, it is beneficial to the smooth rotation of the cleaning part, and on the other hand, it is conducive to a good fit between the concave arc-shaped plate and the cleaning part, thereby improving heat transfer efficiency.

In this example, transitional water tank 6 is not provided, and above structure can refer to shown in accompanying drawing 1,2,4,5, omits other structures of transitional water tank 6 among Fig. 2,4,5 and can constitute this example.

In this example, the liquid outlet part and the heating part share a frame, the frame has a front panel, and the liquid outlet holes 7 are arranged on the front panel, and each liquid outlet hole 7 is connected with the liquid supply assembly, and the heating part assembly and the frame are detachable connect.

Embodiment two:

Embodiment 2 Compared with Embodiment 1, the difference lies in that the heating part fits with the outer circumference of the rotating cylinder 3 in a gap. The technical effect of this arrangement is that on the one hand, the rotational resistance of the rotating cylinder 3 is reduced, on the other hand, the wear is reduced, and further On the one hand, the squeeze on the cleaning part is reduced, which is beneficial to avoid the loss of cleaning liquid caused by the cleaning liquid in the cleaning part being squeezed out.

Embodiment three:

Embodiment 3 Compared with Embodiment 1, the difference is that the heating part and the outer circumference of the rotating cylinder 3 are both close to each other and have a gap fit. The advantage of this setting is that it provides great flexibility and can be flexibly set according to the characteristics of the cleaning part. Sticking and clearance fit, so as to optimize the structure.

Embodiment four:

Embodiment 4 Compared with Embodiments 1, 2 and 3, the difference is that a transition water tank 6 is added, and the heating part is used to heat the cleaning liquid supplied to the cleaning part. At this time, the heating part and the outer circumference of the rotating cylinder 3 preferably have a clearance fit.

After the transition water tank 6 is added, the structure is as follows: a heating part is provided on the outer circumference of the rotating cylinder 3, and the heating part cooperates with the outer circumference of the rotating cylinder 3 in a gap, and the heating part includes the transition water tank 6, and the heating part 5 of the heating part is located in the transition water tank 6 , the transition water tank 6 is used to connect with the water source, and the heating element 5 is used to heat the cleaning liquid in the transition water tank 6, and the heated cleaning liquid flows to the cleaning part, so that the cleaning part is also heated by the heat taken away by the cleaning liquid.

Transition water tank 6 adopts small capacity, and the capacity of this small capacity is less than the capacity of water source.

Preferably, the small capacity is within six times, including six times, the volume of the cleaning liquid supply flow per unit time. The supply of cleaning liquid per unit time is set according to the cleaning needs. Generally speaking, reaching or exceeding this supply is conducive to better cleaning performance, but if the capacity of the transition tank 6 is not limited, it will bring Disadvantage, so the capacity of transition water tank 6 is also very important, just as the present invention says " transition water tank 6 adopts small capacity, and the capacity of this small capacity is less than the capacity of water source.". After the aforementioned design, the amount required for clean use can be better connected like this, while energy consumption can be balanced. In addition, it is also more conducive to the control program to control the opening and closing of the heating element 5. This is because the larger the capacity of the transition water tank 6, the more dynamic use During the process, it is more difficult to control the stability of the working temperature. When the capacity of the transition water tank 6 is small and the supply can be maintained at the same time, then the balance point at this time is more conducive to balancing energy consumption and temperature stability. These three elements are property control and cleaning performance.

The transition water tank 6 is provided with a labyrinth heating flow channel, and the labyrinth heating flow channel is used to rapidly heat the cleaning liquid flowing through the heating element 5 in a short time. In this example, as shown in Figure 7, the labyrinth heating channel of the transition water tank 6 is set as a V-shaped labyrinth heating channel. In addition, in order to better match the rotating cylinder 3, the overall shape of the transition water tank 6 is roughly V-shaped. .

In this example, as shown in Figure 7, the flow direction of the cleaning liquid in the V-shaped labyrinth heating channel is as follows: it flows in from the upper right end of the V-shaped labyrinth heating channel, and then flows out along the V shape to the left upper end of the V-shaped labyrinth heating channel, so that After the design, on the one hand, the flow distance is elongated, so that the cleaning liquid has more time to absorb the heat generated by the heating element 5; The cleaning liquid can better take away the heat generated by the heating element 5 . In addition, due to the V-shape, the flow channels on the left and right sides are relatively close, so when the heating element 5 generates heat, the cleaning liquid in the flow channel from top to bottom on the right side is preheated, and then when it flows from bottom to top on the outlet side , which can heat the cleaning liquid to a higher temperature faster and shorten the heating time. In addition, the V-shaped labyrinth heating channel makes the overall structure very compact. If the heating time needs to be further shortened, the heating element 5 can also be arranged in the flow channel from top to bottom on the right side at the same time.

The above design has the following technical effects: First, the cleaning liquid in the transition water tank 6 is used in the cleaning part after being heated, without long-distance transportation, which greatly reduces waste. In addition, long-distance conveyor belts are also avoided. The second point, from the purpose of the present invention, the amount of cleaning liquid in the transition water tank 6 will not be set a lot, so the heat generated by the heating element 5 is enough to heat the cleaning liquid in the transition water tank 6 in a short time. liquid, thereby being able to quickly enter the normal working state, and the work response is very fast. The third point, when the work is stopped, there is not much cleaning liquid remaining in the transition water tank 6, so the wasted heat is very little. In addition, when the work is stopped, It can be turned off in advance, such as setting the working time to 10 minutes, then when the 10-minute work stop time is reached, the heating element 5 is actively turned off in advance, so that the last heated cleaning liquid is also used to clean the surface to be cleaned, without The heated cleaning liquid cannot be used up; of course, other measures can also be adopted, such as closing the heating element 5 in advance, but making the rotating cylinder 3 continue to rotate, and the hot cleaning liquid remaining in the transition tank 6 continues to be supplied, so that the rotating cylinder Body 3 can thereby clean itself, thereby utilizing the heat of this part of the cleaning liquid remaining in the transition tank 6, so taking this measure can also further reduce waste.

Embodiment five:

As shown in Figures 2, 3, 4, 5, 6, and 7, the arrows in Figure 7 indicate the flow direction of the cleaning liquid. Compared with Embodiment 4, the fifth embodiment is different in that not only the transition water tank 6 is added, but also the heating part is used. To heat the cleaning part of the rotating cylinder 3, specifically in this example, the heating element 5 is arranged around the circumference of the outer circumference of the rotating cylinder 3, and the heating element 5 also includes a heat conducting element while heating the cleaning liquid. The heating element 4 is arranged around the outer circumference of the rotating cylinder 3. The heating element 5 heats the cleaning part of the rotating cylinder 3 through the heat conducting element 4 while heating the cleaning liquid.

The technical effect of this design is: first, the heating in the front and rear directions of the heating element 5 can be applied to the cleaning part more quickly, that is, the front side of the heating element 5 is the cleaning part, and the rear side of the heating element 5 is the cleaning liquid. 5. The heat emitted from the front and rear directions is more efficiently utilized, this is because the front side of the heating element 5 directly heats the cleaning part, and there is no need for the cleaning liquid in the transition tank 6 to carry the heat to heat the cleaning part again, that is to say, the heat is reduced once Conversion, and the advantage of directly heating the cleaning part at the front side of the heating element 5 is that it is also beneficial to improve the compactness of the structure, and the rear side of the heating element 5 cannot directly heat the cleaning part, so the heat is carried by the cleaning liquid in the transition tank 6 and then To superimpose the cleaning part that has been preheated by the front side of the heating element 5, so that the heat emitted by the heating element 5 is used more efficiently. Because the heat is used more efficiently, it is very beneficial to shorten the heating time, so that the work can be achieved in a short period of time. temperature; secondly, while achieving the purpose of more efficient use of heat, it is beneficial to further improve the compactness of the structure, thereby further reducing the thickness of the transition tank 6; thirdly, when designing the V-shaped labyrinth heating channel, The purpose of faster heating can be achieved only by setting the heating element 5 in the bottom-up flow channel on the left side of the V-shaped labyrinth heating flow channel, instead of setting the heating element 5 in both the left and right sides of the V-shaped labyrinth heating flow channel , so that the overall structure is more optimized, and at the same time, it also avoids the waste of heat caused by setting the heating element 5 in the flow of the left and right sides of the V-shaped labyrinth heating flow channel. If the heating element 5 is installed in the flow channel from top to bottom, the heat transfer of the heating element 5 to the right side will inevitably be increased, and because of the speed at which the cleaning liquid absorbs heat, it cannot be absorbed and taken away in time, resulting in heat loss. The above scheme This situation is avoided.

In this example, as shown in Figures 5 and 6, the transition water tank 6 is provided with a second opening 10 on the side facing the rotating cylinder 3, and the second opening 10 allows the heating element 5 to be exposed, thereby reducing the barrier between the heat conducting element 4 and , which is more favorable for the heating element 5 to transfer heat through the heat conducting element 4 . This design can make the heating element 5 closer to the cleaning part, and also make the transition water tank 6 closer to the cleaning part, so that the heated cleaning liquid can be transported to the cleaning part in a shorter distance, and the heated cleaning part and the heating The final cleaning liquid meets faster, thereby minimizing the loss of heat, so that the input of smaller heating power can better maintain the temperature of the cleaning part, that is to say, further improve the energy utilization rate and further improve the response performance.

In this example, as shown in Figures 4, 5, and 6, in order to output the heated cleaning liquid more uniformly, a plurality of liquid outlet holes 7 are arranged in sequence along the axial direction of the rotating cylinder 3, and the liquid outlet holes 7 pass through multiple A communication hole 8 communicates with the outlet end of the V-shaped labyrinth heating channel, therefore, a plurality of liquid outlet holes 7 are located on the upper side of the heat conducting member 4 . The liquid inlet end 11 of the V-shaped labyrinth heating channel communicates with the water source through a pipeline, that is, communicates with the cleaning liquid tank. A water pump can be provided to increase the delivery pressure of the cleaning liquid. The heating element 5 can also be turned off in time by detecting the water level of the cleaning liquid tank and/or whether there is cleaning liquid in the pipeline, so as to achieve higher safety performance, such as anti-dry performance.

For the situation of heating at the same time, other schemes can also be used. For example, the heating element 5 directly heats the cleaning part of the rotating cylinder 3 by the heating element 5 while heating the cleaning liquid, and for example, the heating element 5 is heating While cleaning the liquid, since the transition water tank 6 becomes hot after the cleaning liquid is heated, the cleaning part of the rotary cylinder 3 can be heated by the heated transition water tank 6 .

Embodiment six:

Embodiment 6 is different from Embodiment 5 in that it also includes a scraper 12. The scraper 12 scrapes the cleaning part. The suction port 13 near the dirty plate 12 sucks it away, which is also the working characteristic of the floor scrubber. Then in the sixth embodiment, along the rotation direction of the rotating cylinder 3, the transition water tank 6 is located on the rear side of the scraper plate 12, that is, the cleaning part first scrapes the dirt, and then the heat is supplied by the transition water tank 6, and the heat includes heating through the transition The heat of the cleaning part of the water tank 6 and the heat taken by the heated cleaning liquid when it falls from the liquid outlet hole 7 onto the cleaning part can make more effective use of the heat without wasting the heat on the polluted part of the cleaning part. part (the part of the polluted cleaning department), this is because the heat will be consumed after the cleaning department cleans the surface to be cleaned, so if the sewage is not removed in time, then the part of the cleaning department where the sewage is located (contaminated cleaning The part of the part) will reabsorb heat, and the part of the clean part that is polluted is not conducive to cleaning. Therefore, through the above design, the heat is used more effectively, thereby further reducing waste.

Embodiment seven:

Embodiment eight:

Compared with the above-mentioned embodiments, the eighth embodiment is different in that it also includes a temperature sensor, and the temperature sensor is used to detect the temperature of the heating part and/or the temperature of the cleaning part and/or the temperature of the cleaning liquid supplied to the cleaning part and/or The temperature of the surface being cleaned.

By setting the temperature sensor, the technical effect that can be obtained is: on the one hand, it provides a structural basis for more intelligent control of heating, combined with the control program, it is helpful for further fine control of energy consumption; on the other hand, it can further improve safety and provide There is one more guarantee for safety.

The aforementioned measures are conducive to reducing the volume of the roller brush, or freeing up More space to install other structures, such as shown in Figure 10, since more installation space is vacated, the water pump 26 can also be integrated in the roller brush, in this example, the water pump 26 is located where the liquid inlet joint 16 is this side of the

In this example, the main body 17 not only heats the cleaning liquid, but also conducts heat itself, so the main body 17 can be used to directly heat the cleaning part, that is, the main body 17 is also used as the heat conducting element 4, so that the temperature of the cleaning part rises faster. With this design, not only the response is fast, but also the heat is mainly used for the cleaning part by heating the cleaning liquid and directly heating the cleaning part through the main body 17, so the energy utilization rate is high.
