The upper housing 10 is provided with an elastic snap fastener, and the lower housing 20 is provided with a buckle point that matches the elastic snap fastener. During installation, the upper housing 10 is directly pressed into the lower housing 20. The lower housing 20 is provided with a group of mounting positions for the conjoined electromagnetic air valve 40.

The air channels 22 include an air pump inlet channel, an air valve inlet channel and an air valve outlet channel. The air pump inlet channel and the air valve outlet channel can be defined here as the first air channel 221, the second air channel 222, the third air channel 223, the fourth air channel 224, the fifth air channel 225, the sixth air channel 226, the seventh air channel 227, and the eighth air channel 228, which are used to connect the air inlet 4031 or the air outlet 4032 of the connected solenoid air valve 40 for different purposes; among them, the first air channel 221, the second air channel 222, the third air channel 223, the fourth air channel 224, the fifth air channel 225, and the sixth air channel 226 are air valve outlet channels; the seventh air channel 227 and the eighth air channel 228 are air pump inlet channels. In this embodiment, a common passage 229 is also included. The common passage 229 is the air valve inlet passage, which connects the air outlet 4032 of the air inlet solenoid valve 41 with the air inlet 4031 of each of the air outlet solenoid valves 40. A sealing groove 21 is provided adjacent to the air passage 22 of the lower housing 20. The sealing groove 21 is sealed by a sealing plate 90. The sealing plate 90 is provided with ribs that match the sealing groove 21, ensuring a tight fit with the sealing groove 21 and achieving a sealing effect.

[0029] It is further configured that the first air channel 221 is suitable for connecting to a lumbar support air bag for inflation, the second air channel 222 is suitable for connecting to a coccyx support air bag for inflation, the third air channel 223 is suitable for connecting to one of the kneading air bags for inflation, the fourth air channel 224 is suitable for connecting to another kneading air channel 22, the fifth air channel 225 is suitable for connecting to one of the acupressure air bags for inflation, the sixth air channel 226 is suitable for connecting to another acupressure air bag for inflation, the seventh air channel 227 is suitable for connecting to an air pump for vacuuming, and the eighth air channel 228 is suitable for connecting to an air pump for inflation. Since the coccyx support and lumbar support air bags in massage chairs generally need to be deflated, a deflation-combined electromagnetic valve 45 is provided. The two air outlets 4032 of the deflation-combined electromagnetic valve 45 are connected to the first air path 221 and the second air path 222, respectively, and share the air path with the two air outlets 4032 of the first air inlet-combined electromagnetic valve 41. When the deflation-combined electromagnetic valve 45 is in operation, the two air outlets 4032 of the first air inlet-combined electromagnetic valve 41 are not affected, and the normal operation of other combined electromagnetic valves is not affected. This arrangement ensures that the deflation and intake of a specific air bag do not affect each other, and the shell operates simultaneously, which facilitates a better massage experience and effect when the air bag is in operation. A deflation port 23 connected to the outside world is provided at the position of the air inlet 4031 of the deflation-combined electromagnetic valve 45. Specifically, there are two deflation ports 23, and a sound-absorbing cotton 50 is provided on the back of the air path of the shell to reduce the noise during exhaust.

Its air inlet 4031 is connected to the air outlet 23, and its air outlet 4032 is connected to the first air path 221 and the second air path 222, respectively. In this case, the air outlet 4032 is used for air intake, while the air inlet 4031 is used for air exhaust. The air inlet 4031 of the conjoined electromagnetic air valve 41 is connected to the common channel 229, and the two air outlets 4032 are connected to the air pump for air extraction and inflation, respectively. In this case, the air inlet 4031 and the air outlet 4032 can be used for both air intake and air exhaust. Through this arrangement, the passages of each conjoined electromagnetic air valve 40 are matched one-to-one and arranged reasonably, tightly integrated with the air path 22 on the housing, making the entire structure compact. A seal 80 is also provided between the conjoined electromagnetic air valve 40 and the lower housing 20 to ensure air tightness. The seal 80 can be a rubber member.

[0031] The air passage 22 is provided with an air nozzle adapter 60 for connecting to an air bag or air pump.

Specifically, the air pressure sensor 100 can be provided on the common air inlet passage 229, so that the air valve can monitor the air inlet pressure in real time, facilitating precise adjustment and improving comfort. The air pressure sensor 100 can also realize a memory function under the control of the PCBA control board 30.
