The user can inject the spraying agent for removing formaldehyde into the storage cylinder 112, when the formaldehyde sensor 116 detects that the formaldehyde concentration in the room is higher than the rated value, the formaldehyde sensor 116 sends a signal, the control module receives the signal, the water pump 113 is controlled to start, the water pump 113 pumps the spraying agent in the storage cylinder 112 and sprays the spraying agent to the inner side of the main frame body 2 through the third water pipe 114 and the fourth water pipe 115, so that the spraying agent for removing formaldehyde purifies the gas pumped by the first air pump 5, so that the formaldehyde in the room can be absorbed, when the formaldehyde sensor 116 detects that the formaldehyde concentration in the room is lower than the rated value, the formaldehyde sensor 116 sends a signal, the control module receives the signal, the water pump 113 is controlled to be turned off, the second electric push rod 128 is controlled to start for 3 seconds, the second electric push rod 128 extends for 5 seconds, and the compression rod 94 is pushed to move to the left side, so that the compression rod 94 does not need to be manually moved, meanwhile, the telescopic rod of the second electric push rod 128 extends to drive the second baffle plate 126 on the left side and the rack 124 on the upper side to move to the left side to the leftmost end and then stop, the rack 124 on the upper side is meshed with the straight gear 123, the straight gear 123 is meshed with the rack 124 on the lower side, so that the rack 124 on the lower side drives the second baffle plate 126 on the right side to move to the right side, at the moment, because the air on the upper side of the second baffle plate 126 is purified, after the second baffle plate 126 is opened, the purified air flows downwards, when the distance sensor 131 detects that the distance between the compression bar 94 and the distance is greater than a rated value, the distance sensor 131 sends a signal, the control module receives the signal and starts the second air pump 133 to pump the air on the lower side of the second baffle plate 126, so that the purified air can be pumped out and then is sprayed out through the exhaust pipe 132 and the second mist spray nozzle 134, after 5 seconds, the telescopic rod of the second electric push rod 128 shortens to drive the second baffle plate 126 on the left side and the rack 124 on the upper side to move to the right side to the rightmost end and then stop after the rack 124 on the right side And the second baffles 126 on the two sides move inwards to be closed, the telescopic rods of the second electric push rods 128 do not abut against the compression rod 94 any more, so that the compression rod 94 moves reversely to reset, when the distance sensor 131 detects that the distance between the compression rod 94 and the distance is lower than a rated value, the distance sensor 131 sends out a signal, the control module receives the signal and closes the second air pump 133, and in the process, air can be purified and discharged.

The water supply device is characterized by further comprising a flow limiting mechanism 14, wherein the flow limiting mechanism 14 comprises a fifth fixing column 141, a limiting ring 142, a third baffle 143 and a torsion spring 144, the fifth fixing column 141 is arranged at the top in the second water conveying pipe 98, the limiting ring 142 is arranged on the left side of the second water conveying pipe 98, the third baffle 143 is rotatably arranged on the fifth fixing column 141, and the torsion spring 144 is connected between the front side and the rear side of the third baffle 143 and the fifth fixing column 141.

When water in the second water pipe 98 flows to the first mist spray nozzle 910, the third baffle 143 rotates and no longer blocks the opening of the second water pipe 98, the torsion spring 144 deforms, when no water flows to the first mist spray nozzle 910 in the second water pipe 98, the third baffle 143 rotates reversely to reset under the reset action of the torsion spring 144, the limiting ring 142 blocks the third baffle 143 from reversely overturning under the action of the limiting ring 142, and therefore the water in the first mist spray nozzle 910 cannot flow back.

The power supply device also comprises a control box 3, the control box 3 is arranged on the front lower side of the main frame body 2, a switching power supply, a control module and a power supply module are arranged in the control box 3, the switching power supply supplies power to the whole device, the output end of the switching power supply is electrically connected with the power supply module, the power supply module is connected with a power supply main switch through a circuit, and the control module is electrically connected with the power supply module; the control module is connected with a DS1302 clock circuit and a 24C02 circuit; the contact switch 6, the liquid level sensor 101, the formaldehyde sensor 116 and the distance sensor 131 are electrically connected with the control module, and the first air pump 5, the first electric push rod 105, the water pump 113, the second electric push rod 128 and the second air pump 133 are connected with the control module through peripheral circuits.
