The one-way exhaust port 202 is installed on the other side of the room or outside the wall of the kitchen and toilet where the exhaust can be normally exhausted. First, the exhaust port 202 is far away from the air inlet, which can effectively prevent exhaust gas from being sucked into the room again. Second, the air discharged during ventilation can take away the air in the kitchen and toilet by the way, and take away the peculiar smell of the kitchen and toilet.

Working principle of the utility model:

1. Installation, place the host 1 on the wall of the room, where air can be normally absorbed outside the wall, and the installation of the machine is at a lower position from the ground. The one-way exhaust device 2 is installed on the other side of the room or the position where the wall of the kitchen and toilet can be normally exhausted.

2. Work: Indoor air circulation. When the machine is in the indoor circulation working state, the MCU will close the outdoor air inlet door 106, open the indoor air inlet door 107 at the same time, and start the centrifugal fan 104. The air in the upper part of the room passes through the indoor air inlet 109—the indoor air inlet. Damper 107—air inlet passage 101—filter element 102—inner air passage 103 is sucked into the centrifugal fan 104 and discharged from the lower air outlet. The filtered air is collected in the lower part of the room, while the upper part of the room is at a lower air pressure , the lower set makes the other air in the room flow up, and then is sucked into the host 1 to filter, forming a cycle. At this moment, due to the internal circulation, the indoor and outdoor air pressures are the same, and the one-way exhaust fan blade 105 of the one-way exhaust device 2 is closed by the air outlet 202 by its own weight.

3. Work: Replacement of fresh air. When the MCU determines that it is time to change the indoor air, it will close the indoor air inlet door 107 and open the outdoor air inlet door 106. Under the action of the fan 104, the outdoor air will pass through the outdoor air inlet 110—outdoor Air inlet channel 112—outdoor air inlet door 106—air inlet channel 101—filter element 102 filtering—inner air channel 103—then sucked into the fan 104 and discharged from the lower air outlet, and the layers are collected in the lower part of the room. , due to the addition of new air, the air pressure in the room increases, and the air on the upper part of the room is pressed to open the one-way exhaust fan 105 of the air outlet 202 to be discharged outside. When the time for changing the air arrives, the MCU closes the outdoor air inlet door 106, opens the indoor air inlet door 107, and turns to indoor circulation to save indoor temperature and energy.

4. When using indoors with multiple rooms, each room is equipped with an air exchange and purification host 1, and an air passage 5 is installed on the door or wall of each room. Some doors with poor airtightness can also be installed. Air passage 5, the one-way exhaust door is arranged on the outward ventilation of toilet or kitchen, avoids the counterflow of the air of toilet or kitchen to room indoor.

The above embodiments are only intended to illustrate rather than limit the utility model, so all equivalent changes or modifications made according to the method described in the scope of the patent application of the utility model are included in the scope of the patent application of the utility model.
