Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The purpose of this invention is to provide an integrated pump and valve structure to solve the problems existing in the prior art, which has a compact structure and can effectively reduce volume.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1-5As shown, the present invention provides an integrated pump and valve structure, including an air pump body 1, an air pump circuit board 2, a solenoid valve 3, and a solenoid valve circuit board 4. The first end of the air pump body 1 is provided with an air pump outlet 5. The air pump circuit board 2 is fixedly disposed on the second end of the air pump body 1. The air pump circuit board 2 is communicatively connected to the solenoid valve circuit board 4. The solenoid valve 3 and the solenoid valve circuit board 4 are both fixedly disposed on the first end of the air pump body 1. The air inlet of the solenoid valve 3 is fixedly connected to and communicates with the air pump outlet 5. The solenoid valve circuit board 4 is communicatively connected to the solenoid valve 3 and is communicatively connected to the controller. The controller can control the operation of the air pump body 1 and the solenoid valve 3.

[0028] The integrated pump and valve structure provided by this invention combines the air pump body 1, the air pump circuit board 2, the solenoid valve 3, and the solenoid valve circuit board 4 into one unit. It has a simple structure, high reliability, low cost, high integration design, small size, and convenient installation. It saves most of the space occupied and makes operation simpler and more convenient.

[0029] Furthermore, the integrated pump and valve structure provided by the present invention also includes an air pump protective shell 6 and a solenoid valve protective shell. The air pump protective shell 6 is fixedly disposed on the second end of the air pump body 1. The air pump circuit board 2 is placed in the space enclosed by the air pump protective shell 6 and the second end of the air pump body 1 to protect the air pump circuit board 2 and reduce the possibility of damage caused by the air pump circuit board 2 being exposed. The solenoid valve protective shell is fixedly disposed on the first end of the air pump body 1. The solenoid valve 3 and the solenoid valve circuit board 4 are placed in the space enclosed by the solenoid valve protective shell and the first end of the air pump body 1 to protect the solenoid valve 3 and the solenoid valve circuit board 4 and reduce the possibility of damage caused by the solenoid valve 3 and the solenoid valve circuit board 4 being exposed.

[0030] Furthermore, the first end of the air pump body 1 is provided with several wedges 7, each wedge 7 can be engaged with the solenoid valve protective shell, the structure is simple and the installation is convenient.

[0031] Furthermore, the air pump circuit board 2 and the solenoid valve circuit board 4 are connected via a wiring harness 9. The solenoid valve circuit board 4 is equipped with pins for connecting to the controller, which facilitates a quick connection between the controller and the solenoid valve circuit board 4. The controller connects to the pins to simultaneously command the air pump body 1 and the solenoid valve 3, so that the air pump body 1 and the solenoid valve 3 work together perfectly.

[0032] Furthermore, an oblique opening groove 8 is provided on the first end of the air pump body 1. The oblique opening groove 8 allows the wire harness 9 to pass through, which facilitates the connection between the air pump circuit board 2 and the solenoid valve circuit board 4 through the wire harness 9. The controller controls the solenoid valve 3 and the air pump body 1 at the same time, saving space and making the operation of the solenoid valve 3 and the air pump body 1 more convenient and simple.

[0033] Furthermore, the first end of the air pump body 1 is provided with two baffles 10. The two baffles 10 can be engaged with the solenoid valve circuit board 4 to fix the solenoid valve circuit board 4 and prevent it from shifting or shaking. The structure is simple and easy to install. It should be noted that the number of baffles 10 is not limited to two and can be adjusted according to actual installation requirements.

[0034] Furthermore, the air pump body 1 includes a lower motor cover 11, an air pump motor 12, an upper motor cover 13, an eccentric shaft 14, a connector 15, an intermediate shell 16, an air pump cylinder rubber part 17, an air pump diaphragm plate 18, and an upper air pump shell 19. The lower motor cover 11 is fixedly mounted on one end of the air pump motor 12 and serves to support the air pump circuit board 2. The upper motor cover 13 is fixedly mounted on the other end of the air pump motor 12. One end of the eccentric shaft 14 is fixedly connected to the motor shaft of the air pump motor 12, and an eccentric hole is provided on the other end of the eccentric shaft 14. The connector 15 has a plug-in shaft for inserting into the eccentric hole. Inside, the air pump cylinder rubber component 17 is hinged to the connecting component 15. The air pump motor 12 drives the eccentric shaft 14 to rotate, which in turn causes the connecting component 15 to rotate eccentrically. During this eccentric rotation, the air pump cylinder rubber component 17 moves downwards when pulled by the connecting component 15 and upwards when squeezed by it. Air is released when the air pump cylinder rubber component 17 moves upwards and intake when it moves downwards. An intermediate shell 16 is placed between the motor cover 13 and the air pump cylinder rubber component 17, and it is used to house the air pump cylinder rubber component 17. The upper housing 19 of the air pump is used to support the solenoid valve 3 and the solenoid valve circuit board 4. The diaphragm plate 18 of the air pump is placed between the upper housing 19 of the air pump and the rubber part 17 of the air pump cylinder. The diaphragm plate 18 is covered with an inlet sealing diaphragm and an outlet sealing diaphragm. When air is inlet, the inlet sealing diaphragm can open in one direction. When air is outlet, the outlet sealing diaphragm can open in one direction. The diaphragm-type air pump body 1 is used, which has low noise and large air volume. When the air pump body 1 is working, air enters from the air inlet, is compressed internally, and forms high-pressure gas at the air pump outlet 5, which supplies air to the air pump body 1 and sends the gas to the solenoid valve 3. The solenoid valve 3 delivers the air into the air bag, realizing the massage function of the lumbar support. As a preferred embodiment, the air pipe connector between the solenoid valve 3 and the air bag adopts a snap-fit ​​design, which is firmly fixed and not easy to fall off. An independent pressure limiting valve is also set on the air pump body 1. When the air pressure is too high, it will automatically release pressure, reduce the working intensity of the solenoid valve 3, improve product quality, and extend service life. The outer shell of the air pump body 1 is equipped with heat dissipation structures such as fins, which effectively reduces the temperature of the solenoid valve 3 during use and improves product life. The controller adopts direct control with mechanical buttons, replacing complex control components such as CPU, resulting in low electrical costs.

[0035] Furthermore, the air pump body 1 also includes a clamp 20, which can sequentially clamp the air pump upper shell 19, the air pump diaphragm plate 18, the intermediate shell 16 and the motor upper cover 13. The structure is simple and easy to disassemble and assemble.

[0036] Furthermore, the air pump body 1 also includes screws 21, which are used to fix the air pump motor 12 to the motor cover 13. The structure is simple and easy to disassemble and assemble.

[0037] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
