The device is characterized in that an exhaust fan 13 for exhausting air is fixedly arranged in the device shell, and the position of an air outlet of the exhaust fan 13 is matched with the position of the new air outlet.
An air outlet is formed in the front plate 3, a sealing block 14 matched with the air outlet is fixedly arranged on one side, close to the front plate 3, of the adjusting baffle 7, and a sealing ring 15 for auxiliary sealing is fixedly arranged at the edge of the air outlet.
The operation modes of the adjustable wall-mounted fresh air purifier comprise a pure fresh air mode, a fresh air and internal circulation mode and an exhaust mode. The above modes are specifically as follows:
in the fresh air mode, the fan 1 is operated, the exhaust fan 13 is closed, the adjusting baffle 7 is attached to the front plate 3, and the sealing block 14 is in sealing fit with the exhaust outlet;
in the fresh air and internal circulation mode, the fan 1 is operated, the exhaust fan 13 is closed, the regulating baffle 7 is separated from the front plate 3, a gap exists between the regulating baffle and the front plate, and the sealing block 14 is in sealing fit with the exhaust outlet;

Furthermore, in the state that the adjusting baffle 7 is attached to the front plate 3, the sealing block 14 is in sealing fit with the air outlet, only the air inlet is arranged on the device, so that only outdoor fresh air can be sucked into the device, at this time, the fresh air, the internal circulation mode and the air duct of the air exhaust mode are blocked, and after the outdoor fresh air enters the fresh air fan, the fresh air is filtered by a filter screen and other filtering devices or other filtering modes, and clean air is discharged into a room.
In a state that the adjusting baffle 7 is separated from the front plate 3 with a gap between the adjusting baffle 7 and the front plate, and the sealing block 14 is in sealing fit with the air outlet, the inner circulation flow area is formed between the equipment shell and the adjusting baffle 7, and indoor air can pass through the inner circulation primary filter screen 11 and circulate to the inside of the equipment; simultaneously, outdoor air passes through the fresh air inlet, passes through the fresh air primary filter screen 10, circulates towards the inside of the equipment, merges with the internal circulation air in the fresh air flowing cavity, and flows into the air filtering cavity together.
As the opening size of the regulating shutter 7 is changed, the size of the internal circulation flow region is also changed. The larger the internal circulation flow area is, the larger the air quantity of internal circulation air is in the running process of the equipment, and the smaller the air quantity of the internal circulation air is in the opposite direction. Therefore, on the premise that the rotation speed of the fan 1 is stable, that is, when the total air volume of the fan 1 is stable, the specific gravity of the air volumes of the internal circulation air and the fresh air in the total air volume can be adjusted by controlling the air volume of the internal circulation air. For example, when the adjusting damper 7 is opened to a certain extent, the air volume ratio of the internal circulation air to the fresh air is 2:3, and when the adjusting damper 7 is gradually increased, the air volume ratio of the internal circulation air to the fresh air may be 4:1.
It should be noted that, in the above adjustment modes, tightness between other parts of the device and between the other parts and the outside air needs to be ensured, and sealing modes that can be adopted include a rubber sealing ring 15, foam, various expansion hoses, and the like.
In the state that the adjusting baffle 7 is separated from the front plate 3, a gap exists between the adjusting baffle 7 and the front plate, and the sealing block 14 is separated from the air outlet, the tightness between the adjusting baffle 7 and the front plate 3 is broken, indoor air can directly enter the equipment, and at the moment, the air outlet of the air outlet fan 13 is aligned with the fresh air outlet, and the air is exhausted outwards. At this time, the indoor air can directly enter the exhaust fan without passing through a material such as a filter screen, which forms resistance to the air flow, and is discharged outdoors through the fresh air port by means of the exhaust fan 13.
According to the invention, the front cover of the fresh air purifier is arranged in a movable mode, so that the relative position of the internal structural parts of the fresh air purifier is effectively adjusted in the running process of the equipment, the respective air inlet ratio of fresh air and internal circulation of the fresh air purifier is more flexibly adjusted, complicated operations such as filter screen replacement or equipment shell replacement in the traditional adjusting mode are avoided, and the integral automation degree of the equipment is improved. Meanwhile, in the actual use process, the fresh air and the internal circulation can independently operate, so that the operation efficiency and the purification quality of the equipment are remarkably improved, the selection of users is enriched, and the user experience is improved. In addition, due to the structural change, the internal structure of the equipment is simplified, and the complexity of the machine body is greatly reduced, so that the whole size of the equipment is smaller, and the equipment meets the development requirements of light weight, thinness and miniaturization of products.
In conclusion, the invention has good use effect, strong operability in the running process, high automation degree and high use and popularization value.
