[0030] The air valve control assembly 4 includes an upper airbag air hose 402, an air pump 403, an air valve cover 404, a four-way air hose 405, an exhaust hose 406 for the air pump, an upper air supply hose 407, an air hose 408 for the lower air valve, an lower air supply hose 409, an intermediate air supply hose 410, an intermediate one-way air valve 411, an intermediate one-way air valve 412, an intermediate solenoid valve 413, an intermediate solenoid valve 414, an intermediate airbag air hose 415, an air bag air hose 416, and an intermediate air valve air hose 417.

[0031] In the embodiment of the present invention, the operating principle of the portable pneumatic massage device wrapped around the leg is specifically as follows.

[0032] In the initial state, the air pump 403 and the three corresponding solenoid valves are all powered off and deflating. When operation begins, the air pump 403 and the lower solenoid valve 414 are energized, and air is sent through the air pump 403 to the air pump exhaust hose 406, then to the four-way air pipe 405, and then sequentially through the lower air supply hose 409, the lower one-way air valve 412, the lower air valve air hose 408, the lower solenoid valve 414, and the lower airbag air hose 416 to the lower air chamber 23 of the airbag 20. The lower air chamber 23 of the airbag 20 begins to inflate, the air pressure increases, and an air pressure massage effect is achieved in the area of ​​the lower air chamber 23. When the lower air chamber 23 reaches a certain air pressure, the intermediate solenoid valve 413 is energized, opening the air path, and air is sent via the air pump 403 to the exhaust hose 406 for the air pump, then to the four-way air hose 405, and then sequentially through the intermediate supply hose 410, intermediate one-way air valve 411, intermediate air valve air hose 417, intermediate solenoid valve 413, and intermediate air bag air hose 415 before entering the intermediate air chamber 22 of the airbag 20. The intermediate air chamber 22 of the airbag 20 begins to inflate, increasing the air pressure and achieving an air pressure massage effect in the area of ​​the intermediate air chamber 22. At the same time, due to the action of the lower one-way air valve 412, the air in the lower air chamber 23 does not flow back, and the lower air chamber 23 can still maintain a high-pressure state. When the intermediate air chamber 22 reaches a certain air pressure, the upper solenoid valve 401 is energized, opening the air path, and air is sent via the air pump 403 to the exhaust hose 406 for the air pump, then to the four-way air hose 405, and then sequentially through the upper air supply hose 407, the upper solenoid valve 401, and the upper airbag air hose 402 to the upper air chamber 21 of the airbag 20. The intermediate air chamber 22 of the airbag 20 begins to inflate, increasing the air pressure and achieving an air pressure massage effect in the area of ​​the upper air chamber 21. At the same time, due to the action of the intermediate one-way air valve 411 and the lower one-way air valve 412, air in the lower air chamber 23 and the intermediate air chamber 22 does not flow back, and the lower air chamber 23 and the intermediate air chamber 22 can still maintain a high-pressure state. When the air pressure in all three air chambers reaches a certain level, the power to the air pump 403, upper solenoid valve 401, intermediate solenoid valve 413, and lower solenoid valve 414 is all turned off, the air pump 403 stops supplying air, and the air in the air chambers leaks out through the corresponding air leak holes in the upper solenoid valve 401, intermediate solenoid valve 413, and lower solenoid valve 414, causing the air pressure in the airbag 20 to decrease and eventually allowing it to be rolled up and stored.

[0033] In this embodiment of the present invention, the pneumatic assembly 2 forms multiple air chambers with irregular shapes, and based on the repeated asynchronous expansion and contraction of these multiple air chambers with irregular shapes, an ideal pneumatic massage effect is achieved. The overall structure is simple and compact, provides a good massage effect, and its rollable, thin, and lightweight structure makes storage easy, providing a superior user experience.
