[0014] Technical effects and advantages of the present invention: 1. The present invention is provided with a ventilation assembly. Under the joint action of the first electric fan and the second electric fan, the outside air can quickly enter the room through the housing of the ventilation duct, and the filter screen is used to precipitate impurities in the outside air on the mesh surface. Due to long-term use, the impurities deposited on the filter screen are increasing, and the idle filter material available for filtering is decreasing. The accumulated impurities will block the filter screen, so that less air passes through the filter screen, and the thrust of the air flow on the filter screen will become greater and greater. Finally, the air flow pushes the filter screen, and the filter screen moves so that the conductor sheet is connected to the electrode head, and then the air pump is powered to inflate the air cylinder, so that the piston moves, and then the turntable is driven to rotate. When the piston moves to one end of the air cylinder, the turntable rotates half a circle, so that the second fan blows to the outside, and the precipitated impurities are blown to the outside by the wind force of the fan, so that it is avoided that the filter is manually disassembled to remove the filter screen for cleaning or replacement of the filter element, which is conducive to reducing labor costs.

[0015] 2. The present invention is provided with a resistor component, and the top of the mesh frame is connected to a slider. The movement of the filter drives the movement of the slider, so that the slider moves on the sliding resistor to change the resistance. When the filter moves toward the second fan, the resistance of the first fan increases, and the corresponding resistance of the second fan decreases, so that the power of the second fan increases and the power of the first fan decreases. The wind force of the second fan is greater than that of the first fan, so that impurities can be blown outdoors. When the impurities in the filter are cleaned, the filter is reset under the wind force of the second fan. Similarly, the sliding resistor returns to its initial state, which is conducive to improving the degree of impurity cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

Due to long-term use, the impurities deposited by the filter assembly 102 are increasing, and the idle filter material available for filtering is decreasing. The accumulated impurities will block the filter assembly 102, making the air passing through the filter assembly 102 less, and the thrust of the air flow on the filter assembly 102 will also be increasing. Finally, the air flow pushes the filter assembly 102, and the filter assembly 102 moves so that the conductor sheet 1023 connects to the electrode head 1094, and then the air pump 1091 is energized to inflate the air into the air cylinder 1095, so that the piston 1101 moves, and then the turntable 1112 rotates half a circle, so that the second fan 1116 blows toward the outside, and the wind force of the fan is used to blow the precipitated impurities to the outside, avoiding manual disassembly of the filter to remove the filter for cleaning or replacement of the filter element, which is conducive to reducing labor costs.

The movement of the filter assembly 102 drives the movement of the slider 2012, so that the slider 2012 moves on the sliding resistor 2011 to change the resistance. When the filter assembly 102 moves toward the second fan 1116, the resistance of the first fan 107 increases, and the corresponding resistance of the second fan 1116 decreases, so that the power of the second fan 1116 increases and the power of the first fan 107 decreases. The wind force of the second fan 1116 is greater than the wind force of the first fan 107, so that impurities can be blown to the outside. When the impurities in the filter assembly 102 are cleaned, the filter assembly 102 is reset under the wind force of the second fan 1116.

[0036] Reference Fig.11 The dust suction pipe 302 has an open groove on one side facing the filter assembly 102 .

[0037] The working principle of the present invention is as follows: through the joint action of the first fan 107 and the second fan 1116, the outside air can quickly pass through the tube shell assembly 101 into the room, and the filter assembly 102 is used to precipitate impurities in the outside air on the mesh surface. Due to long-term use, the impurities deposited on the filter assembly 102 are increasing, and the idle filter material available for filtering is decreasing. The accumulated impurities will block the filter assembly 102, making the air passing through the filter assembly 102 less, and the thrust of the air flow on the filter assembly 102 will also be greater and greater. Finally, The air flow pushes the filter assembly 102, and the movement of the filter assembly 102 causes the conductor sheet 1023 to connect to the electrode head 1094, and then the air pump 1091 is energized to inflate the air into the air cylinder 1095, causing the piston 1101 to move, thereby pushing the turntable 1112 to rotate. When the piston 1101 moves to one end of the air cylinder 1095, the turntable 1112 rotates half a circle, causing the second fan 1116 to blow toward the outdoors, and the wind force of the fan is used to blow the precipitated impurities toward the outdoors, avoiding manual disassembly of the filter to remove the filter for cleaning or replacement of the filter element, which is conducive to reducing labor costs.

[0038] The movement of the filter assembly 102 drives the movement of the slider 2012, so that the slider 2012 moves on the sliding resistor 2011 to change the resistance. When the filter assembly 102 moves toward the direction of the second fan 1116, the resistance of the first fan 107 increases, and the corresponding resistance of the second fan 1116 decreases, so that the power of the second fan 1116 increases and the power of the first fan 107 decreases. The wind force of the second fan 1116 is greater than the wind force of the first fan 107, so that impurities are blown to the outside. When the impurities in the filter assembly 102 are cleaned, the filter assembly 102 is reset under the wind force of the second fan 1116. Similarly, the variable resistor assembly 201 returns to its initial state, which is beneficial to improving the degree of impurity cleaning.
