Example 1

As shown in FIG1 , this embodiment provides a switch valve, including a housing 1 and a valve core 2. An installation space 11 is formed inside the housing 1. The valve core 2 is arranged in the housing 1. The valve core 2 can be rotatably arranged. The pipe body is inserted between the inner wall of the housing 1 and the valve core 2. A blocking structure 22 is formed on the outer wall of the valve core 2. The blocking structure 22 has a blocking position for pressing the pipe body and a release position away from the pipe body. The blocking structure 22 is formed on the outer wall of the valve core 2. After the pipe body is inserted between the valve core 2 and the housing 1, the blocking structure 22 can be rotated to have a blocking position for pressing the pipe body and a release position away from the pipe body. When the blocking structure 22 is at the blocking position, the blocking structure 22 presses the pipe body, so that the flow area inside the pipe body becomes smaller. When the blocking structure 22 is at the release position, the blocking structure 22 does not press the pipe body, and the liquid flows normally in the pipe body. By changing the position of the blocking structure 22, the flow area of the pipe body is controlled, thereby switching the pipeline. This solution has the advantages of simple structure and low cost.

As shown in Figures 2 and 3, it should be noted that the shape of the protrusion is an arc. In this embodiment, the height of the arc is the distance between the inner wall of the shell 1 and the valve core 2, ensuring that when the protrusion abuts against the tube body, the tube body is completely blocked to ensure that no liquid flows through the tube body. As an alternative embodiment, the shape of the protrusion can be square or truncated cone. As an alternative embodiment, the height of the protrusion can be less than the distance between the inner wall of the shell 1 and the valve core 2. The protrusion set in this way plays a role in reducing the flow of the tube body, thereby reducing the flow of the pipeline. The height of the protrusion can be adjusted according to actual needs to meet actual needs.

As shown in Fig. 4, the valve core 2 further includes a fixing ring 21, wherein the blocking structure 22 is arranged on the outer periphery of the fixing ring 21. The fixing ring 21 is fixedly connected to the blocking structure 22. In this embodiment, in order to ensure the stability of the connection, an integral molding method is selected. As an alternative implementation method, the blocking structure 22 can also be connected to the fixing ring 21 by welding or bonding.

Specifically, there are a plurality of blocking structures 22, and the plurality of blocking structures 22 are arranged along the outer periphery of the fixing ring 21; in this embodiment, the blocking structures 22 are arranged relatively on the outer periphery of the fixing ring 21, and two blocking structures 22 are arranged on one fixing ring 21, and the two blocking structures 22 are arranged relatively on the outer periphery of the fixing ring 21. During use, the two blocking structures 22 just abut against the water pipe 5 entering the housing 1, and the provision of a blocking structure 22 can improve the blocking effect.

Specifically, there are several fixing rings 21, and the several fixing rings 21 are arranged at intervals along the extension direction of the shell 1. A tube body is correspondingly arranged on the outer periphery of each fixing ring 21. Several fixing rings 21 can correspond to several tube bodies, so as to meet the simultaneous control of multiple pipelines. In this embodiment, there are two fixing rings 21, and the two fixing rings 21 are arranged at intervals along the extension direction of the shell 1. Blocking structures 22 are respectively arranged on the outer periphery of the two fixing rings 21. The on-off state of the two pipelines can be controlled by two groups of blocking structures 22. The two fixing rings 21 are manufactured by an integral molding method. As an alternative embodiment, they can also be connected by welding or bonding.

Specifically, the blocking structure 22 is arranged at an angle along the extension direction of the shell 1. In the present embodiment, the angle between the connecting line of the two blocking structures 22 located on the periphery of the same fixed ring 21 and the connecting line of the two blocking structures 22 located on the periphery of the other fixed ring 21 is a right angle. When one group of the blocking structures 22 is in the blocking position, the other group of the blocking structures 22 is in the open state, so that one valve core 2 can realize different state control of the two tube bodies, further increasing the practicality of the device.

As an alternative embodiment, the connecting angle of the blocking structures 22 located on the periphery of different fixed rings 21 can also be an acute angle, and the blocking effect of the blocking structure 22 can be achieved by controlling the fixed ring 21 to rotate to a specified position. For example, when the connecting angle of the two groups of blocking structures 22 is 45 degrees, when the first group of blocking structures 22 is in the blocking position, the second group of blocking structures 22 is in the releasing position, and then the fixed ring 21 is rotated 45 degrees, and both groups of blocking structures 22 are in the releasing position, and then the fixed ring 21 is rotated 45 degrees, the first group of blocking structures 22 is in the releasing position, and the second group of blocking structures 22 is in the blocking position, and by adjusting the connecting angle between the blocking structures 22 on each two fixed rings 21, the switching effect of the fixed ring 21 rotating at different angles on the tube body can be changed. Further, the size of the connecting angle between the blocking structures 22 on each two fixed rings 21 and the rotation speed of the fixed ring 21 can be changed to achieve the time when the tube body is in different states.

It should be noted that, as shown in FIG5 , there can also be four fixing rings 21, and the four fixing rings 21 are all manufactured by an integral molding method, and a blocking structure 22 is arranged on the periphery of each fixing ring 21, and the first layer of blocking structures 22 has one, which is in the shape of an arc. The second layer of blocking structures 22 has one, which is in the shape of a truncated cone. The third layer of blocking structures 22 has two, which are arranged oppositely. The fourth layer of blocking structures 22 is in the shape of an arc, and has two, which are arranged oppositely. The shapes of the blocking structures 22 on the periphery of each fixing ring 21 can be the same or different, and the number of blocking structures 22 on the periphery of each fixing ring 21 can also be the same or different, and the specific design is carried out according to actual needs.

Furthermore, a through hole 13 is provided on the side wall of the housing 1. The through hole 13 is suitable for the tube to pass through. In this embodiment, there are four through holes 13, and the four through holes 13 are divided into two groups, each group being arranged opposite to each other. In this embodiment, the through holes 13 are in the shape of long strips. It should be noted that the number of the through holes 13 is twice the number of the tube. The shape of the through holes 13 can also change its size and shape according to the shape of the tube.

Furthermore, a driving structure 3 is provided, which is fixed inside the housing 1 and is suitable for driving the valve core 2 to rotate. In the embodiment, the driving end of the driving structure 3 is fixedly connected to the valve core 2, and the bottom of the driving structure 3 is fixedly connected to the housing 1, thereby ensuring the stability of the driving structure 3 in the process of driving the valve core 2 to rotate.

The driving structure 3 uses a stepper motor, which has the advantages of precise and stable transmission. The number of steps of the stepper motor is controlled by electronic control programming, thereby achieving precise control of the valve core 2.

Furthermore, a mounting structure 4 is provided, and the mounting structure 4 is connected to the housing 1; specifically, the mounting structure 4 includes a mounting plate 41 and a mounting column 42, and the mounting plate 41 is generally provided at one end of the housing 1, and the mounting plate 41 is fixedly connected to the housing 1. In this embodiment, the mounting plate 41 is welded to the housing 1. Specifically, there are two mounting columns 42, and the two mounting columns 42 are arranged on the mounting plate 41 at intervals, and an installation space 11 is formed between the two mounting columns 42. The drive structure 3 is placed in the installation space 11, and the drive structure 3 is fixed to the housing 1 by clamping through the two mounting columns 42. The drive structure 3 arranged in this way has the advantage of easy disassembly.

Further, the pipeline structure includes water pipes 5, and there are only two water pipes 5, which are arranged at intervals along the extension direction of the axis of the shell 1, wherein the water pipes 5 penetrate the shell 1. The water pipes 5 are made of flexible material, and the water pipes 5 are bent into a U shape; the two parallel side arms of the water pipes 5 both pass through the shell 1. The part of the water pipes 5 located inside the shell 1 is arranged in contact with the inner wall of the shell 1.

It should be noted that the medium in the water pipe 5 is water in this embodiment, but as an alternative embodiment, it may also be oil or other liquids, gases or solids.

It should be noted that the water pipe 5 is made of rubber, further polyethylene, or PVC or other materials.
