[0074] In the embodiment, the second electric control valve device 2 includes two electromagnetic valves, which are a first electromagnetic valve and a second electromagnetic valve. The first interface 804 of the first electromagnetic valve is the side wing air inlet 201, the second interface 805 of the first electromagnetic valve is connected with the first interface 804 of the second electromagnetic valve, the third interface 806 of the first electromagnetic valve is the side wing air inlet 202, and the third interface 806 of the second electromagnetic valve is the side wing air outlet 203. When the electromagnetic coil 13 of the first electromagnetic valve is powered on, the iron column 9 and the iron core 10 in the first electromagnetic valve are attracted to each other under the action of the magnetic field, the iron column 9 moves to the direction of the iron core 10 against the elastic force of the spring 11, at this time, the rubber pad 12 and the iron core 10 are in complete contact, the second passage 802 of the first electromagnetic valve is closed, and the first passage 801 of the first electromagnetic valve is opened; the gas in the high-pressure gas source or the low-pressure gas source flows into the side wing air bag through the first passage 801 of the first electromagnetic valve and the third passage 803 of the first electromagnetic valve, so as to realize side wing air charging. When the electromagnetic coils 13 of the first electromagnetic valve and the second electromagnetic valve are not powered on, the iron columns 9 of the first electromagnetic valve and the second electromagnetic valve move away from the iron core 10 under the action of the elastic force of the spring 11, block the first passage 801 of the first electromagnetic valve and the second electromagnetic valve, and the gas in the side wing air bag flows out from the second passage 802 of the first electromagnetic valve through the gap between the iron column 9 and the inner wall of the valve body 8 of the first electromagnetic valve, but the gas is blocked by the rubber pad 12 of the second electromagnetic valve at the first passage 801 of the second electromagnetic valve, so that the gas in the side wing air bag cannot flow out from the first passage 801 of the second electromagnetic valve, so as to realize side wing pressure maintaining. When the electromagnetic coil 13 of the second electromagnetic valve is powered on and the electromagnetic coil 13 of the first electromagnetic valve is not powered on, the rubber pad 12 of the second electromagnetic valve blocks the second passage 802 of the second electromagnetic valve, and the first passage 801 of the second electromagnetic valve is opened; the rubber pad 12 of the first electromagnetic valve moves and blocks the first passage 801 of the first electromagnetic valve under the action of the elastic force of the spring 11, and the second passage 802 of the first electromagnetic valve is opened. Since there is a gap between the valve core and the inner wall of the valve body 8 of the first electromagnetic valve, the gas in the side wing air bag can flow out through the third passage 803 of the first electromagnetic valve, the gap between the valve core and the inner wall of the valve body 8 of the first electromagnetic valve, the second passage 802 of the first electromagnetic valve, the first passage 801 of the second electromagnetic valve, and the third passage 803 of the second electromagnetic valve, so as to realize side wing air discharging.

When the electromagnetic coil 13 of the third electromagnetic valve is energized, the iron column 9 and the iron core 10 in the third electromagnetic valve are attracted to each other under the action of the magnetic field, and the iron column 9 moves to the iron core 10 direction against the elastic force of the spring 11. At this time, the rubber pad 12 and the iron core 10 are in complete contact, the massage air outlet 503 of the third electromagnetic valve is closed, the first channel 801 of the third electromagnetic valve is opened, and the gas from the air pump flows into the massage air bag through the massage air inlet 501 of the third electromagnetic valve to realize massage inflation. When the electromagnetic coil 13 of the third electromagnetic valve is not energized, the iron column 9 of the third electromagnetic valve moves away from the iron core 10 under the elastic force of the spring 11, blocks the first channel 801 of the third electromagnetic valve, opens the massage air outlet 503, and the gas in the massage air bag passes through the gap between the valve core and the iron core 10, and finally is exhausted through the second channel 802 of the third electromagnetic valve to realize massage deflation.

The gas of the air pump flows from the first channel 801 of the fourth electromagnetic valve, through the third channel 803 of the fourth electromagnetic valve and the third channel 803 of the fifth electromagnetic valve, into the first channel 801 of the fifth electromagnetic valve, and finally into the waist support air bag, so as to realize the inflation of the waist support. When the electromagnetic coil 13 of the fifth electromagnetic valve is not powered on, the iron column 9 of the fifth electromagnetic valve moves under the action of the elastic force of the spring 11, blocks the first channel 801 of the fifth electromagnetic valve, so that the gas in the waist support air bag cannot flow out, so as to realize the pressure maintaining of the waist support. When the electromagnetic coil 13 of the fourth electromagnetic valve is not powered on and the electromagnetic coil 13 of the fifth electromagnetic valve is powered on, the first channel 801 of the fourth electromagnetic valve is closed, the second channel 802 of the fourth electromagnetic valve is opened, the first channel 801 of the fifth electromagnetic valve is opened, and the second channel 802 of the fifth electromagnetic valve is closed.
