Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a solenoid valve group of a massager. Background Art

[0002] With the development of technology, people pay more and more attention to physical health and quality of life. Therefore, various health care devices have emerged, including pneumatic massagers. Such devices are mainly used to help people relieve muscle tension, relax nerves and relieve pain, etc. The working principle of a pneumatic massager is mainly to achieve the movement of its execution unit through inflation and deflation. During the working process, the solenoid valve plays a crucial role. The solenoid valve is one of the core components of a pneumatic massager, mainly responsible for controlling the on-off of the air path and regulating the pressure change. The selection and use of the solenoid valve have a direct impact on the quality of the pneumatic massager.

[0003] However, there may be some problems with the traditional solenoid valve fixing method. First of all, the solenoid valve is usually fixed to the device by hard connection methods such as bolts. This method easily causes the solenoid valve to be subjected to a large impact force during the rapid inflation and deflation process, resulting in vibration and loosening. Secondly, the vibration and loosening of the solenoid valve may further affect the normal operation of the entire pneumatic massager, and may even cause equipment failure. Summary of the Utility Model

[0021] The following further elaborates in detail on the specific embodiments of the present utility model in conjunction with the attached Figure 1-6 drawings.

[0022] From Figure 1-6Provided is a solenoid valve group of a massage instrument of the present utility model, which includes a bottom plate 10, a solenoid valve assembly 20 installed on the bottom plate 10, a buffer structure 30 arranged between the surface of the bottom plate 10 and the solenoid valve assembly 20, an air inlet pipe 40 and an air outlet pipe 50 connected to the solenoid valve assembly 20, and a solenoid valve group cover 60 covering the outside of the solenoid valve assembly 20 and fixed to the bottom plate 10. By arranging the buffer structure 30 between the solenoid valve assembly 20 and the bottom plate 10, when the solenoid valve assembly 20 is opened and closed, the buffer structure 30 can buffer the vibration of the solenoid valve assembly 20, thereby playing a role in noise reduction.

[0023] The buffer structure 30 is a rubber cushion plate. The lower surface of the rubber cushion plate is adhesively fixed to the bottom plate 10, and the upper surface of the rubber cushion plate is adhesively fixed to the solenoid valve assembly 20, the air inlet pipe 40 and the air outlet pipe 50. The thickness of the rubber cushion plate is 2 - 4 mm. Through the setting of the rubber cushion plate, when inflating and deflating, the vibration of the solenoid valve assembly 20 can be buffered, and the rubber cushion plate can play a good role in vibration isolation between the solenoid valve assembly 20 and the bottom plate 10.

[0024] In some embodiments, the number of the solenoid valve assemblies 20 is 2 - 4. Each solenoid valve assembly 20 can be separately connected to an execution unit of the massage instrument. By controlling the inflation and deflation of each solenoid valve assembly 20, different execution units of the massage instrument can be controlled.

[0025] The following is a specific embodiment of the solenoid valve assembly 20:

[0026] The solenoid valve assembly 20 includes two solenoid valve housings 21, two solenoid valve rods 22 movably arranged in the two solenoid valve housings 21, a connection cavity 23 fixedly connected to the upper ends of the two solenoid valve housings 21, and two connectors 24 fixed to both sides of the upper end of the connection cavity 23 for connecting to the air circuit of the massage instrument. The lower side surfaces of the two solenoid valve housings 21 are respectively connected to the air inlet pipe 40 and the air outlet pipe 50 through a connecting pipe 25. The solenoid valve housing 21 connected to the air inlet pipe 40 is used to inflate the air circuit of the massage instrument, and the solenoid valve housing 21 connected to the air outlet pipe 50 discharges the air circuit of the massage instrument. For specific reference, Figure 3 And Figure 4 , when inflating, the solenoid valve housing 21 connected to the air inlet pipe 50 is electrified, so that the solenoid valve rod 22 moves and opens the valve, enabling the gas in the air inlet pipe 50 to enter the solenoid valve housing 21 and then enter the air circuit of the massage instrument through the upper connection cavity 23. On the contrary, when deflating, the solenoid valve housing 21 for inflating is powered off, and the solenoid valve housing 21 for deflating is electrified, so that the solenoid valve rod 22 therein moves and opens the valve. In this way, the air in the air circuit of the massage instrument enters the corresponding solenoid valve housing 21 through the connection cavity 23 and then is discharged through the air outlet pipe 50.

[0027] In some embodiments, an internal thread hole 61 is provided inside the lower end of the solenoid valve group housing 60, and a connecting bolt 70 is connected between the bottom plate 10 and the internal thread hole 61.

[0028] Further, in order to further reduce noise, the lower end of the solenoid valve housing 21 is open and adhesively fixed to the surface of the rubber cushion plate. The lower end of the solenoid valve housing 21 is closed by the rubber plate. A rubber block 26 is fixed to the lower end of the solenoid valve rod 22. A through hole 27 is provided through the rubber block 26. With the arrangement of the rubber block 26, please refer to Figure 5 When the solenoid valve rod 22 moves, its lower end will not directly collide with the bottom of the solenoid valve housing 21, but collide with the surface of the rubber cushion plate through the rubber block 26. In addition, with the arrangement of the through hole 27, when not energized, the lower end of the solenoid valve rod 22 is closed by the contact between the rubber block 26 and the rubber cushion plate. When energized, the solenoid valve rod 22 moves upward, so that the air flowing in from the intake pipe 40 enters the solenoid valve rod 22 through the through hole 27, and then enters the connecting cavity 23.

[0029] It can be understood that an electromagnet is fixed to the top of the solenoid valve housing 21. The solenoid valve rod 22 is a hollow shaft rod structure, and a return spring is connected between the lower end of the solenoid valve rod 22 and the lower end of the solenoid valve housing 21.

[0030] A control wire socket 80 is fixed to the solenoid valve group housing 60. The intake pipe 40 is threadedly connected with an intake joint 41, and the intake joint 41 is connected to an air pump.

[0031] It is worth mentioning that both ends of the exhaust pipe 50 are open, and ventilation holes 62 are provided through the solenoid valve group housing 60. In this way, when deflating, the discharged air will enter the solenoid valve group housing 60 and then be discharged from the ventilation holes 62. When discharging, it will also take away part of the heat inside the solenoid valve group housing 60, achieving a good heat dissipation effect.

[0032] The innovation of the solenoid valve group of the present utility model lies in the design of multiple solenoid valve components to achieve precise control of the massager, and effectively suppress the vibration and noise of the solenoid valve through structures such as a buffer rubber cushion plate. At the same time, considering the heat dissipation requirements, heat dissipation treatment is carried out through the design of the solenoid valve group housing and ventilation holes. The overall structure design is scientific and reasonable, effectively reducing the operating noise of the equipment.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
