[0040] In the regulating valve group 121, each regulating valve group 121 includes a regulating air-inflating valve 1212 and a regulating air-exhaust valve 1211. The regulating air-inflating valve 1212 is a normally closed two-position three-way valve, having an air inlet I, a working port C and an air outlet B. When the power is off, the air inlet I is blocked, and the working port C is connected to the air outlet B; when the power is on, the air inlet I is connected to the working port C, and the working port C is blocked from the air outlet B. The regulating air-exhaust valve 1211 is a normally closed two-position two-way valve, having an air inlet A and an air outlet H. When the power is off, the air inlet A is blocked from the air outlet H; when the power is on, the air inlet A is connected to the air outlet H. The air inlet I of the regulating air-inflating valve 1212 receives the air supply from the air pump 11 after passing through the muffler filter 17, the working port C is connected to the regulating airbag 4, and the air outlet B is connected to the air inlet A of the regulating air-exhaust valve 1211. In the air circuit, when the regulating airbag 4 needs to be inflated, the regulating inflation valve 1212 is energized, and the pressure can be maintained after the inflation is completed; when the regulating airbag 4 needs to be deflated, the regulating inflation valve 1212 is de-energized, and the regulating exhaust valve 1211 is energized to discharge the gas in the regulating airbag 4. During the inflation process of the regulating airbag 4, since the air pressure sensor 14 is connected in series in the air circuit, the air pressure sensor 14 can detect the air pressure value in the regulating airbag 4.

[0041] In this embodiment, four regulating valve groups 121 are provided, which can control the inflation and exhaust of 4-8 regulating airbags 4.

[0042] The hardness regulating valve assembly 12 also includes a regulating air intake pipe 122 and a regulating air exhaust pipe 123.

In this air circuit, when the massage inflation valve 1312 is energized, the massage airbag 5 can be inflated, and the massage airbag 5 can be inflated and pressed. Since the massage exhaust valve 1311 is a normally open structure, after the massage inflation valve 1312 loses power, the massage exhaust valve 1311 does not need to work, and the air pressure in the massage airbag 5 can be discharged, and the massage airbag 5 contracts, thereby realizing the massage function; when it is necessary to maintain the air pressure in the massage airbag 5, the massage exhaust valve 1311 is energized.

[0044] In this embodiment, the massage valve group 131 has five groups, which respectively control the inflation and deflation of five massage airbags 5, namely, one neck massage airbag, two shoulder massage airbags, one waist massage airbag and one leg massage airbag.

[0045] The massage valve assembly 13 also includes a massage air inlet pipe 132 , which is connected in series with the regulating air inlet pipe 122 via a hose. The air inlets K of the five massage inflation valves 1312 are all connected to the massage air inlet pipe 132 , which facilitates the polling operation of the five massage valve groups 131 .

[0046] The entire air circuit structure also includes a controller 10, which is electrically connected to the air pump 11, the hardness regulating valve assembly 12, the massage valve assembly 13 and the air pressure sensor 14 to control the operation of the air pump, the hardness regulating valve assembly, the massage valve assembly and the air pressure sensor. The air pump 11, the silencer filter 17, the regulating air intake pipe 122, the massage air intake pipe 132 and the air pressure sensor are connected in series in sequence. When the airbags corresponding to the massage valve group 131 and the regulating valve group 121 are inflated by polling and switching operations, the air pressure sensor can query the pressure values ​​of the airbags one by one, and the controller 10 and the corresponding algorithm determine the adjustment method of each area to achieve pressure adjustment of the corresponding airbag.

[0047] When the gas passes through the silencer filter device 17, a swirl is generated in the silencer filter device 17, which affects the gas outlet speed, thereby achieving a silencer effect.
