Further, as shown in fig. 1 and 2, the air purifier with the dust removing device with a filter screen further comprises a cleaning assembly 40, the cleaning assembly 40 is located between the air inlet 101 and the filter screen 20, the cleaning assembly 40 comprises a lifting driving device 401 and a cleaning member 402, the cleaning member 402 is located on one surface of the filter screen 20 facing away from the blower 301, the cleaning member 402 is fixedly connected with a push rod of the lifting driving device 401 and moves up and down along with the push rod, and the fixed connection manner includes, but is not limited to, threaded connection or welding, when the lifting driving device 401 acts, the cleaning member 402 contacts the filter screen 20. In this embodiment, the lifting driving device 401 is implemented as an electric push rod, the cleaning member 402 is implemented as a brush, and when the lifting driving device 401 works, the brush repeatedly moves up and down on the surface of the filter screen 20 away from the blower 301, and the dust on the filter screen 20 is swept by the bristle of the brush.

It should be noted that, assuming that the blower 301 is stopped at this time, although the filter screen 20 is arranged vertically, when the brush cleans dust on the filter screen 20, the dust is more floated below or near the air inlet 101, and there is still a risk that the dust enters the air inlet chamber 102.

In view of this, as shown in fig. 1, the fan assembly 30 further includes a first rotating member 302 and a rotation driving device 303, where one end of the first rotating member 302 is fixedly connected to the rotation shaft of the rotation driving device 303, and the fixed connection manner includes, but is not limited to, welding or coupling connection, the other end of the first rotating member 302 extends into the air intake chamber 102, the blower 301 is fixedly mounted on the first rotating member 302, and when the rotation driving device 303 works, the first rotating member 302 follows the rotation shaft of the rotation driving device 303 to perform a rotation motion, and since the blower 301 is fixedly mounted on the first rotating member 302, the blower 301 follows a rotation by a predetermined angle.

Specifically, the bottom wall of the air intake chamber 102 has a mounting hole (not shown), a bearing (not shown) is disposed in the mounting hole, and one end of the first rotating member 302, which is away from the rotation driving device 303, penetrates through the inner ring of the bearing, and then extends upward from the bottom wall of the air intake chamber 102 by a predetermined distance.

When the cleaning member 402 cleans dust attached to the filter 20, the blower 301 provides wind force to blow the dust away to the direction of the air outlet 104, so as to avoid the risk of dust entering the air inlet chamber 102 during dust removal; in addition, the wind power of the blower 301 is matched with the acting force of the cleaning member 402, so that the dust adhering to the filter screen 20 is more easily cleaned, and the advantage that the dust is not easy to stay on the filter screen 20 in the dust removal process is realized. When the dust removal is finished, the rotary driving device 303 is rotated 180 degrees again, and the working state before the dust removal is recovered. By arranging the rotary driving device 303, the blower 301 can be used for one machine, and the production cost is reduced.

During the dust removal process, the dust which is swept off and blown off is discharged from the air outlet 104 to the outside or falls into the dust collection chamber 105 through the opening 1051, and the dust collection chamber 105 is used for collecting dust.

It should be noted that, when the air purifier with the dust collector with the filter screen is in a normal operation state, that is, the air inlet area of the blower 301 faces the filter screen 20, and the air outlet area of the blower 301 faces the disinfection chamber 103, if the opening 1051 is not closed, the air flowing from the air inlet 101 enters the opening 1051, but does not completely pass through the filter screen 20 and enter the air inlet chamber 102.

In order to avoid the above phenomena, as shown in fig. 2 and 3, the air purifier with the dust collector with the filter screen further comprises a normally closed door 50, the normally closed door 50 comprises a second rotating member 501 and a door body 502, the second rotating member 501 is fixedly connected with the door body 502, the fixed connection mode is preferably welding, the second rotating member 501 is rotatably installed in the box 10, the second rotating member 501 is in power connection with the first rotating member 302, and when the rotation driving device 303 acts, the door body 502 closes or opens the opening 1051.

To solve the second problem described above, further, the number of teeth of the first bevel gear 5011 is twice the number of teeth of the second bevel gear 603 or the reference diameter of the second pulley 604 is twice the base diameter of the first pulley 305. When the blower 301 is turned 180 ° by adjusting the transmission ratio, the door 502 is turned 90 °.

Further, to prevent the driving belt 602 from interfering with the movement of the cavity wall in the case 10, as shown in fig. 1, the air purifier with the dust collector with the filter screen 20 further includes two second rotating shafts 605, wherein the two second rotating shafts 605 are located between the first rotating member 302 and the first rotating shaft 601, a third belt pulley 606 is disposed on each second rotating shaft 605, the driving belt 602 is wound on the third belt pulley 606, one third belt pulley 606 is located on the inner side of the driving belt 602, and the other third belt pulley 606 is located on the outer side of the driving belt 602.
