Description

Technical Field

[0001] This utility model relates to the field of control valve technology, and in particular to gas control valves. Background Technology

[0002] The solenoid valve has a sealed chamber with through holes at different positions, each hole connecting to a different air tube. Inside the sealed chamber is a piston with electromagnets at both ends. When the coil of the electromagnet at one end is energized, the piston is attracted and moves accordingly. By controlling the movement of the piston, the through holes are opened or closed.

[0003] Currently, pneumatic massage uses solenoid valves as switches to control the compressed air circuit. A massage chair typically has multiple massage airbags. Each massage airbag requires one circuit. The switch of each circuit is controlled by an independent solenoid valve. Therefore, a massage chair requires multiple solenoid valves for control. This results in a large and expensive controller structure composed of solenoid valves. In addition, the solenoid valves generate noise when engaged, and the heat generated during prolonged operation reduces the electromagnetic force, leading to airtightness issues.

[0036] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0037] Example 1

[0038] like Figure 1-6 As shown, this embodiment provides a massage airbag control valve, including a stepper motor 1, a moving valve 7 driven by the stepper motor 1, a fixed valve 8 matched with the moving valve 7, and a gas inlet / outlet seat 10 communicating with the fixed valve 8. The fixed valve 8 is provided with an inlet hole 81 and two or more outlet holes 82. The moving valve 7 is provided with a guide groove that connects one or more outlet holes 82 with the inlet hole 81. The gas inlet / outlet seat 10 is provided with a gas inlet 101 communicating with the inlet hole 81 and two or more gas outlets 102 communicating with the two or more outlet holes 82.

[0039] The inlet hole 81 of the fixed valve component 8 is located in the middle, and two or more outlet holes 82 are located on the outer periphery of the inlet hole 81. The distance between the inlet hole 81 and each outlet hole 82 is equal. When there are three or more outlet holes 82, the adjacent outlet holes 82 are equidistant or unequal.

[0040] The guide channel includes an inlet chamber 75, an inlet channel 71, and an adapter channel 72. The inlet chamber 75 is connected to the inlet hole 81. One end of the inlet channel 71 is connected to the inlet chamber 75, and the other end is connected to the adapter channel 72. The adapter channel 72 is connected to any one or two or more outlet holes 82. The inlet channel 71 and the adapter channel 72 together form a T-shape.

[0041] In some embodiments, the air intake passage 71 and the adapter passage 72 together form a figure-7 shape.

[0042] In some embodiments, the air intake passage 71 and the adapter passage 72 together form a Y-shape.

[0043] Of course, the air intake channel 71 and the adapter channel 72 can also be in other shapes.

[0044] The fixed valve 8 and the moving valve 7 are tightly fitted together to ensure that no gas leakage occurs when the inlet hole 81, the guide groove, or any one or more outlet holes 82 are connected, and the outlet holes 82 that are not connected to the inlet hole 81 or the guide groove are not covered by the moving valve 7.

[0045] The moving valve 7 is equipped with a driving component 6 driven by a stepper motor 1. The driving component 6 has a mounting position that matches the moving valve 7. The moving valve 7 can be installed with the driving component 6 by welding, snap-fitting, screwing, or other methods.

[0050] When the distance between all the discharge holes 82 is the same, the connection is achieved by connecting the inlet hole 81 with any one or two discharge holes 82. When the distance between the discharge holes 82 is not the same, it can be adjusted according to the requirements. For example, a single discharge hole 82 can be designed on one side of the valve component 8, and multiple discharge holes 82 can be designed on the other side, or other different distance layouts of the discharge holes 82 can be used to achieve the connection between the inlet hole 81 and different numbers of discharge holes 82.

[0052] In some embodiments, all discharge holes 82 are spaced at the same distance. When the guide groove connects the inlet hole 81 and the two discharge holes 82, the positions of the two ends of the adapter channel 72 correspond to the two discharge holes 82 respectively.

[0053] In some embodiments, when the spacing between all the discharge holes 82 is not uniform and the guide channel allows the inlet hole 81 to be connected to only one discharge hole 82, the adapter channel 72 covers a single discharge hole 82.

[0055] By rotating the angle of the moving valve 7, the inlet hole 81 is connected to the outlet holes 82 at different positions and in different numbers, so as to precisely control the gas filling and releasing of each massage airbag and improve the control efficiency of more than two massage airbags.

[0056] The specific control quantity can be adjusted according to needs, and is not limited to the above embodiments.

[0057] The massage airbag control valve is equipped with a Hall electronic element 84. The installation position of the Hall electronic element is not limited, as long as it can confirm the initial position of the moving valve 7.

[0058] Working principle description: Each air tube connector 3 connected to multiple discharge ports 82 is connected to a corresponding massage airbag, and each air tube connector 3 connected to the inlet port 81 is connected to an air source. Taking the connection of inlet hole 81 to one or two outlet holes 82 as an example, during operation, stepper motor 1 drives drive component 6 to rotate, which in turn drives valve component 7 to rotate.
