Of course, in other embodiments, the housing 210 may be additionally provided with a fresh air inlet; the fresh air device 200 further includes a valve assembly disposed on the housing 210, where the valve assembly is used to open or close the dirty air outlet 213 and the fresh air inlet. Further, the valve assembly includes a first valve and a second valve, the first valve and the second valve are movably disposed in the housing 210, the first valve is used for opening or closing the dirty air outlet 213, and the second valve is used for opening or closing the fresh air inlet, and when the fresh air inlet is opened, the fresh air inlet is communicated with the second chamber 218. The fresh air device 200 comprises three working modes, namely a pollution discharge mode, a purification mode and a fresh air mode:

When the fresh air device 200 is in the blowdown mode, the valve plate 230 opens the fresh air inlet 212 and closes the clean air inlet 211, and at the same time the first valve opens the fresh air outlet 213 and the second valve closes the fresh air inlet; the indoor dirty air enters the second chamber 218 of the shell 210 from the dirty air inlet 212 under the action of the fan 308, is not purified by the fresh air component 220, enters the first chamber 217 through the air inlet, and flows to the dirty air outlet 213 to be discharged outdoors.

When the fresh air device 200 is in the purification mode, the valve plate 230 opens the purification air inlet 211 and closes the dirty air inlet 212, while the first valve closes the dirty air outlet 213; the indoor polluted air enters the second chamber 218 from the purified air inlet 211 under the action of the fan 308, is purified by the fresh air component 220, enters the first chamber 217 through the air inlet, and is conveyed back into the room through the air duct 214. It should be noted that, when the fresh air device 200 is in the purification mode, the fresh air inlet may be in an open state or a closed state, and when the second valve opens the fresh air inlet, outdoor fresh air may be introduced while purifying indoor air; when the second valve closes the fresh air inlet, only indoor air is purified.

When the fresh air device 200 is in the fresh air mode, the valve plate 230 simultaneously closes the dirty air inlet 212 and the clean air inlet 211, and at the same time, the second valve opens the fresh air inlet, and the first valve closes the dirty air outlet; outdoor fresh air enters the second chamber 218 from a fresh air inlet under the action of the fan 308, is purified by the fresh air component 220, enters the first chamber 217, and is conveyed into the room through the air duct 214.

In this way, the fresh air device 200 can be switched to different indoor air purification modes according to the needs of the user, so that the indoor air can be effectively purified, the indoor air quality is improved, and the flexibility and convenience of use are provided for the user.

To ensure that the fresh air device 200 can reliably implement a purge mode and a blowdown mode; with continued reference to fig. 3 and 4, the fresh air device 200 further includes a first supporting member 301 and a second supporting member 302, where the first supporting member 301 and the second supporting member 302 are connected to the housing 210 and located in the second chamber 218; the first supporting pieces 301 and the second supporting pieces 302 are distributed at intervals, and the fresh air component 220 is arranged between the first supporting pieces 301 and the second supporting pieces 302, so that the fresh air component 220 is assembled inside the shell 210 through the first supporting pieces 301 and the second supporting pieces 302; one side of the first supporting piece 301 facing away from the fresh air component 220 forms a dirty air channel 303 with the inner wall of the shell 210; one side of the first supporting member 301 facing the fresh air component 220 forms a purifying channel 304, and the fresh air component 220 is located in the purifying channel 304; the dirty air inlets 212 are distributed relative to the dirty air channels 303, and the clean air inlets 211 are distributed relative to the clean air channels 304.

Thus, when the fresh air device 200 is in the blowdown mode, the valve plate 230 opens the dirty air inlet 212 and closes the clean air inlet 211, the fan 308 introduces the indoor dirty air from the dirty air inlet 212 into the second chamber 218, flows to the first chamber 217 through the dirty air channel 303 and the air inlet, flows to the dirty air outlet 213, and is conveyed outdoors through the dirty air outlet 213; because the fresh air component 220 does not extend into the dirty air channel 303, when the indoor dirty air is discharged, the dirty air cannot be purified by the fresh air component 220, so that the fresh air component 220 is not easy to dirty, and the service life of the fresh air component 220 is prolonged.

When the fresh air device 200 is in the purification mode, the valve plate 230 opens the purification air inlet 211 and closes the dirty air inlet 212, the fan 308 introduces indoor dirty air from the purification air inlet 211 into the second chamber 218, flows through the purification channel 304, is purified by the fresh air component 220, enters the first chamber 217 through the air inlet, and is finally conveyed into the room through the air duct 214; because the purifying air inlet 211 is opposite to the purifying channel 304, the dirty air introduced into the housing 210 by the fan 308 can reliably flow to the fresh air component 220, so that the fresh air component 220 can reliably purify the dirty air and then convey the dirty air back to the room in the purifying mode of the fresh air device 200, and the indoor air can be effectively purified.

When the fresh air device 200 is in the fresh air mode, the valve plate 230 simultaneously closes the purification air inlet 211 and the dirty air inlet 212, the fan 308 introduces outdoor fresh air into the second chamber 218 through the fresh air inlet, flows through the purification channel 304, is purified through the fresh air component 220, enters the first chamber 217 through the air inlet, and is finally conveyed indoors through the air duct 214; in order to ensure that the introduced outdoor fresh air can reliably flow into the fresh air component 220 for purification, the fresh air inlet is configured to be opposite to the purification channel 304, so that the fresh air introduced into the shell 210 by the fan 308 can reliably flow to the fresh air component 220, and further, the fresh air component 220 can reliably purify the fresh air and then convey the purified fresh air into a room in a fresh air mode of the fresh air device 200, and the indoor air cleanliness and air quality are effectively improved.

It should be noted that, the fresh air component 220 may select a filter screen with various functions according to needs, for example: a filter for purifying formaldehyde, a high efficiency air filter (HEPA filter), etc., are not particularly limited herein.

Referring to fig. 5, in the present embodiment, the valve plate 230 is rotatably disposed on the housing 210, and the fresh air device 200 further includes a motor 290, wherein the motor 290 is in transmission connection with the valve plate 230 and is used for driving the valve plate 230 to rotate so as to alternatively open the dirty air inlet 212 and the clean air inlet 211, or simultaneously close the dirty air inlet 212 and the clean air inlet 211. The motor 290 drives the valve plate 230 to rotate, so that the dirty air inlet 212 and the clean air inlet 211 can be reliably opened and closed.

Optionally, the shape of the valve plate 230 is similar to a fan shape, and only the valve plate 230 needs to be ensured to be capable of closing the clean air inlet 211 and the dirty air inlet 212 at the same time; the fan-like valve plate 230 can reduce the material used for preparing the valve plate 230 to reduce the cost.

In order to further reduce the volume of the fresh air device 200, a compact structural design of the fresh air device 200 is realized; the motor 290 is disposed inside the housing 210.
