Description

Electronic cigarette with high sensitivity Technical Field

The present invention relates to the technical field of electronic atomization, and more specifically, to an electronic cigarette with high sensitivity.

Background Art

Existing electronic cigarettes generally include a battery assembly and an atomization assembly. The battery assembly is equipped with a battery and a control circuit for supplying power to the electronic cigarette. The atomization assembly includes a heating unit. When the heating unit is powered on, it can atomize the solution to be atomized, i.e., the atomizing liquid, into vapor mist, aerosol or electronic cigarette smoke for the user to inhale. The atomizing liquid includes cigarette liquid or medicine liquid, herbal essence liquid, etc.

In existing electronic cigarettes, the airflow sensor is generally arranged in the battery assembly and shares an air intake channel with the smoke channel. The battery assembly is generally far away from the suction port, so the air intake airflow encounters greater resistance. The air intake airflow generated when the user smokes takes a while to trigger the airflow sensor. In this way, the airflow generated when the user smokes cannot be instantly sensed, and the heating element is powered on and started more slowly, making the electronic cigarette less sensitive.

Embodiments of the present invention

The present invention will be described in detail below with reference to the accompanying drawings.

Embodiment 1:

As shown in Fig. 1 and Fig. 2, the electronic cigarette with high sensitivity in the embodiment of the present invention is composed of a mouthpiece 1, an outer shell 2, an atomizer assembly and a battery assembly, and the atomizer assembly and the battery assembly are respectively arranged inside the outer shell and on the left and right sides. Among them, the outer shell 2 includes a front shell 21 and a rear shell 22, and the rear shell 22 is box-shaped. The atomizer assembly and the battery assembly are arranged in the rear shell 22, and the front shell 21 is covered on the rear shell 22. In other embodiments, the atomizer assembly and the battery assembly can also be connected up and down.

The atomization assembly includes a liquid storage cup 4 for storing atomized liquid and an atomization core 6 for heating and evaporating the atomized liquid. The battery assembly includes a battery 7 and a PCB control board 8 for providing power to the atomization core 6. The suction nozzle 1 is arranged at one end of the outer shell and connected to the atomization assembly. The suction nozzle 1 is provided with an airflow sensing channel 10 and an airflow sensor 3, and the airflow sensor 3 is arranged in the airflow sensing channel 10. When airflow is generated in the airflow sensing channel 10, the airflow sensor 3 can be triggered by the airflow. The airflow sensor 3 can also be a microphone or an air pressure sensor, which can be used to detect the inhalation airflow or inhalation negative pressure generated by the inhalation action. When the inhalation action is detected, the airflow sensor 3 is triggered to start the electronic cigarette to power on. The airflow sensor 3 is arranged in the suction nozzle 1, which can shorten the distance between the airflow sensor 3 and the suction port 110 to the maximum extent, so that the airflow generated by the user when smoking can be sensed more quickly, and the airflow sensor 3 can be triggered more quickly, so that the electronic cigarette works more sensitively, and the sensitivity of the electronic cigarette product can be maximized. In addition, the airflow sensing channel 10 is separately arranged from the electronic cigarette smoke channel, so as to avoid the problem that the airflow sensor cannot work due to the large amount of condensation in the smoke channel, which is easy to be blocked and further makes the electronic cigarette unable to work.

As shown in Figures 1 to 4, the nozzle portion 1 includes a nozzle shell 11 and a nozzle bottom plug 12. The upper end of the nozzle portion 1, that is, the upper end of the nozzle shell 11, is provided with a suction port 110. The nozzle bottom plug 12 is sleeved on the inner bottom end of the nozzle shell 11, and the bottom of the nozzle bottom plug 12 is connected to the upper end of the liquid storage cup 4. The airflow sensing channel 10 is provided in the nozzle bottom plug 12 through the upper and lower parts. The upper and lower penetration here is not limited to vertical penetration, and may also have a certain inclination or curvature or meander upward. The airflow sensing channel 10 is provided with a accommodating cavity 120, and the airflow sensor 3 is provided in the accommodating cavity 120. When the inhaled airflow passes through the airflow sensor 3 in the airflow sensing channel 10, the airflow sensor 3 can be triggered. The bottom of the accommodating cavity 120 is connected to the cavity where the battery assembly is located, that is, the lower section of the airflow sensing channel 10 is connected to the cavity where the battery assembly is located.

The outlet of the airflow sensing channel 10 on the nozzle bottom plug 12 extends upward and is provided with an outlet pipe 123, which protrudes from the upper plane of the nozzle bottom plug 12, so as to prevent condensation generated on the inner wall of the nozzle part 1 from dripping onto the upper plane of the nozzle bottom plug 12 and then flowing back into the airflow sensing channel 10, thereby preventing the condensation from corroding and damaging the airflow sensor 3 so that it cannot work normally.

The nozzle bottom plug 12 is also provided with a smoke outlet 121 to suck the smoke generated by the atomization core 6 into the nozzle portion 1 .

A first liquid filling port 122 for filling atomized liquid is also provided on the bottom plug 12 of the suction nozzle. A plunger 111 is provided on the inner bottom of the suction nozzle shell 11 and is inserted into and sealed at the first liquid filling port 122. The first liquid filling port 122 is connected to a second liquid filling port 414 provided at the upper end of the liquid storage cup 4. The bottom of the first liquid filling port 122 abuts against the upper plane of the second liquid filling port 414, so that the two can be sealed and connected.

The nozzle bottom plug 12 can be made of a soft material such as a silicone material, so that it has sealing properties when connected to the nozzle shell 11 and the upper end of the liquid storage cup 4.

As shown in Figures 5 and 6, the upper end of the liquid storage cup 4 is provided with an upward inner surrounding wall 411, and the outer side of the inner surrounding wall 411 is also provided with an outer wall 412. The nozzle bottom plug 12 is sleeved on the inner wall of the inner surrounding wall 411, and the lower wall of the nozzle shell 1 is sleeved between the inner surrounding wall 411 and the outer wall 412. The inner surrounding wall 411 and the outer wall 412 are provided with a notch 413 on one side corresponding to the airflow sensor 3 so that the lower section of the airflow sensing channel 10, that is, the horizontal section, passes through.

As shown in FIG. 2 and FIG. 5 to FIG. 8 , the atomization assembly further includes an atomization tube 5, and an atomization core 6 is disposed in the atomization tube 5. An upper end transverse wall 41 and a cup bottom cover 42 are disposed at the upper end of the liquid storage cup 4, and the cup bottom cover 42 blocks the bottom opening disposed at the liquid storage cup 4. An annular groove 421 is disposed on the outer wall of the cup bottom cover 42, and a sealing ring 422 is disposed on the annular groove 421. The two ends of the atomization tube 5 are respectively connected to the upper end transverse wall 41 and the cup bottom cover 42 disposed at the liquid storage cup 4, and the inner wall of the liquid storage cup 4 and the outer wall of the atomization tube 5 and the cup bottom cover 42 enclose a liquid storage cavity 40.

A first through hole 410 is provided on the upper transverse wall 41 of the liquid storage cup, and the upper end of the atomizer tube 5 is inserted into the first through hole 410. A second through hole 420 is provided on the cup bottom cover 42, and the lower end of the atomizer tube 5 is inserted into the second through hole 420. In this embodiment, the upper end of the atomizer tube 5 is also inserted into the smoke outlet hole 121 of the bottom plug 12 of the nozzle.

The inner diameter and outer diameter of the upper part of the atomizer tube 5 are respectively smaller than the inner diameter and outer diameter of the lower part thereof, so that the larger atomizer core 6 can be installed in the lower part of the atomizer tube 5, and the smaller upper part of the atomizer tube 5 can make the liquid storage chamber 40 have a larger space to store more atomized liquid. In this embodiment, the atomizer core 6 is a tubular atomizer core 6 and is sleeved on the inner lower part of the atomizer tube 5. The wall of the atomizer tube 5 located at the tubular atomizer core 6 is provided with a liquid inlet through hole 51, so that the atomized liquid in the liquid storage chamber 40 can be absorbed by the tubular atomizer core 6 after passing through the liquid inlet through hole 51.

As shown in Figures 1, 2, and 8, the tubular atomizing core 6 includes a tubular absorbing liquid 61, a heating element (not shown) and an electrode pin 62. The heating element is arranged inside the tubular absorbing liquid 61. After the tubular absorbing liquid 61 absorbs the atomized liquid, the atomized liquid can be infiltrated and conducted to the surface of the heating element. When the heating element is energized, the atomized liquid can be heated and evaporated into smoke. The smoke can be emitted from the inner tube hole of the tubular absorbing liquid 61 and flow upward through the inner tube hole of the atomizing tube 5. The tubular absorbing liquid 61 is made of nanoporous ceramic material. After the atomized liquid passes through the nanoporous material, the evaporated smoke particles are finer and the smoking taste is better. An insulating ring 52 is also connected to the bottom of the tubular atomizing core 6 in the atomizing tube 5. The electrode pin 62 of the tubular atomizing core 6 is arranged in the insulating ring 52. The atomizing tube 5 is generally made of metal material. The insulating ring 52 can prevent the electrode pin 62 from touching the atomizing tube 5 and causing a short circuit failure.

As shown in FIG1 , a button 211 and a transparent lens 212 are provided on the front shell 21. The button 211 is connected to the button switch 81 provided on the PCB control board 8, that is, the button switch 81 can be controlled by pressing the button 211. In this embodiment, the working power of the atomizer core 6 can be adjusted by pressing the button 211, and the atomization amount can be further adjusted to meet the customer's demand for the amount of smoke. A display screen 82 is provided on the PCB control board 8 under the transparent lens 212. The display screen 82 can display parameters such as the remaining battery power, the remaining amount of atomizer liquid, and the working power of the atomizer core. The bottom of the rear shell 22 is also provided with a shell air inlet through hole 220, and a through hole 221 for a USB charging interface is also provided. The USB charging interface 83 is installed on the PCB control board 8 and extends from the through hole 221.

As shown in Figures 1, 2 and 9, the atomizer assembly and the battery assembly are respectively arranged on the left and right sides of the housing. A silicone base 9 is also arranged between the lower part of the cup bottom cover 42 and the inner bottom of the outer housing, and a base air inlet through hole 90 connected to the bottom of the atomizer tube 5 is arranged on the silicone base 9.

The working principle of the electronic cigarette with high sensitivity in this embodiment is as follows: as shown in FIG. 2 , when the user inhales from the suction port 110 , negative pressure is generated inside the suction nozzle. In the direction indicated by the continuous solid arrow a in the figure, the external gas enters from the air inlet hole 220 of the shell, passes through the air inlet hole 90 of the base and the bottom of the atomizer tube 5 to the inner tube hole of the tubular atomizer core 6 . At the same time, in the direction indicated by the continuous solid arrow b in the figure, the external gas enters from the air inlet hole 220 of the shell, passes through the cavity where the battery assembly is located, and enters the air flow sensing channel 1 0. When passing through the airflow sensor 3, the airflow sensor 3 is triggered. After the airflow sensor 3 is triggered, the heating element of the tubular atomizing core 6 is powered on through the PCB control board. The heating element can heat the atomized liquid in the tubular absorbing liquid 61 and evaporate it into smoke. The smoke can be emitted from the inner tube hole of the tubular absorbing liquid 61. At this time, driven by the external gas entering the tubular atomizing core, the smoke flows upward from the inner tube hole of the atomizing tube 5 and is sucked into the user's mouth after passing through the smoke outlet hole 121 and the suction port 110 on the bottom plug 12 of the suction nozzle. While the heating element is working and the atomized liquid is evaporated into smoke, the atomized liquid in the liquid storage chamber 40 flows downward in the direction indicated by the continuous hollow arrow c in the figure, enters the liquid inlet through hole 51 of the atomizing tube 5, and is absorbed by the tubular absorbing liquid 61, so that the heating element can be continuously replenished for atomization.
