The system comprises a first-stage filtering module 1, a second-stage filtering module 2, a third-stage filtering module 3 and a reversing module 4, wherein the first-stage filtering module 1 is used for filtering particle impurities with a first preset size in gas sucked by a fan 9 under negative pressure, the second-stage filtering module 2 is used for separating the impurities in the gas passing through the first-stage filtering module 1 through centrifugal action, the third-stage filtering module 3 is used for filtering particle impurities with a second preset size in the gas passing through the second-stage filtering module 2, the second preset size is smaller than the first preset size, the gas passing through the third-stage filtering module 3 is sent into a room or an outdoor through the fan 9, and the reversing module 4 is used for changing a gas inlet channel entering the first-stage filtering module 1, wherein the gas inlet channel comprises an outdoor fresh air inlet channel 5 and a dust-containing gas inlet channel 6 in a device with an air purifying system.
In one possible manner of this embodiment, the secondary filtering module 2 includes at least one conical cyclone 21, an airflow guiding port 21a is disposed along a tangential direction of the conical cyclone 21, the air passing through the primary filtering module enters the conical cyclone through the airflow guiding port, small particle impurities in the conical cyclone settle to the bottom under the action of centrifugal force and gravity, so that the separated impurities settle from the bottom 21b of the conical cyclone, and the filtered air flows out from the top 21c of the conical cyclone. Wherein the air flow guide port 21a should be provided at a position near the top of the conical cyclone 21 so that the air entering the conical cyclone 21 is more effectively separated from the impurities. And, a detachable dust box 8 is provided at the bottom of the conical cyclone 21 for collecting the impurities settled from the bottom of the conical cyclone 21.
The number of the conical cyclone separators 21 in the secondary filter module 2 is not particularly limited in this embodiment, and may be, for example, 1 or a plurality of conical cyclone separators 21. When the secondary filter module 2 is composed of a plurality of conical cyclone separators 21, the conical cyclone separators 21 are closely abutted to each other and are arranged in a circular shape, so that the impurity separation effect is improved.
In one possible manner of this embodiment, the primary filtering module 1 includes a sealing housing 11 sleeved on an outer wall of the conical cyclone 21, a sealing cavity 12 formed between the sealing housing 11 and the conical cyclone 21, and a filtering mesh enclosure 13 disposed in the sealing cavity 12 and sleeved on the outer wall of the conical cyclone 21, where the filtering mesh enclosure 13 has a filtering hole 13a with a first preset size, and an air flow inlet 11a is disposed on the sealing housing 11. The height of the filter screen 13 is identical to that of the seal chamber 12, and the seal housing 11 makes it necessary for the gas entering the seal chamber 12 from the gas inlet 12a to pass through the filter screen 13 for the first coarse filtration, and the gas filtered through the filter screen 13 enters the conical cyclone 21 for the second filtration through the gas flow guide port 21a of the conical cyclone 21.
In addition, the conical cyclone separator top 21c is connected with a tertiary filter module 3, and the tertiary filter module 3 is arranged in the fresh air cavity 7. The three-stage filtering module 3 is a detachable HEPA filter screen and is installed through a filter screen bracket 10 arranged in the fresh air cavity 7. The filtered gas directly enters the fresh air cavity 7 after flowing out from the top of the conical cyclone separator, and is filtered for the third time in the fresh air cavity, so that the system is compact in structure and does not occupy redundant multiple spaces.
In one possible manner of this embodiment, the reversing module 4 includes a motor 41, a cavity 42, and a slider 43 disposed inside the cavity 42 and connected to the motor 41, where the cavity 42 is communicated with the primary filter module 1 through a cavity and a primary filter module communication port 44, and the motor 41 drives the slider 43 to move, so that the cavity 42 is communicated with the outdoor fresh air inlet channel 5 or with the dust-containing air inlet channel 6 inside the device with the air purification system.

Under the action of negative pressure suction of the fan 9, outdoor fresh air enters the sealing cavity 12 through the air inlet 12a on the sealing shell 11 and is filtered through the first stage of the filter screen 13. Then the air flow enters the conical cyclone separator from the air flow guide opening 21a of the conical cyclone separator 21, small particle impurities in the conical cyclone separator settle to the bottom under the action of centrifugal force and gravity, so that the separated impurities settle from the bottom 21b of the conical cyclone separator, and the filtered air flows out from the top 21c of the conical cyclone separator. And the second stage of filtering is realized. The settled impurities fall into the detachable dust box 8 and can be removed after a certain time. The gas flowing out from the top 21c of the conical cyclone separator enters the fresh air cavity 7, is filtered by a detachable HEPA filter screen arranged in the fresh air cavity 7, completes the third-stage filtration, and then sends the fresh air with the third-stage filtration into a room through a fan 9.
When the inside of the device with the air purification system needs to be cleaned, the motor 41 in the reversing module 4 drives the sliding block 43 to move, and the sliding block 43 moves to block the outdoor fresh air inlet channel 5, so that the first-stage filtering module 1 and the dust-containing air inlet channel 6 in the device with the air purification system are communicated through the cavity 42. The device with the air purifying system can be an air conditioner, and dust-containing air in the device is deposited in an air duct, a filter screen and the like in the air conditioner due to long-term use of the air conditioner. Under the action of negative pressure suction of the fan 9, dust deposited in an air duct and the like in the air conditioner enters the primary filter module 1 along with air flow and then sequentially passes through the secondary filter module 2 and the tertiary filter module 3. The three-stage filtration is the same as the fresh air filtration principle, and is not described in detail herein. The three-stage filtered dust-containing gas can be sent into a room or enter the rest pipeline to be led out of the room.
