Indoor air purifier with self-cleaning function

Abstract

The utility model discloses an indoor air purifier with a self-cleaning function, which comprises an air purifier shell, a motor is arranged on the inner wall of the top end of the air purifier shell, and a first gear is arranged on an output shaft of the motor. Through rotary connection of the connecting rod, when the reciprocating sliding block ascends, the cleaning brush inclines downwards due to the resistance of the filter screen, the contact face between the cleaning brush and the filter screen is lowered, the resistance is reduced, and therefore the situation that dust on the filter screen is driven to move upwards in the ascending process of the cleaning brush is avoided; and when the cleaning brush descends along with the reciprocating sliding block, the cleaning brush rotates upwards to be horizontal, so that the brush face of the cleaning brush is in complete contact with the filter screen, dust on the filter screen is brushed away downwards, and compared with the prior art, the problem that dust is accumulated on the upper portion of the cleaning brush is effectively solved.

By setting a rotating wheel to wind and release the pull rope, and cooperating with a heavy object, the cleaning brush can be moved up and down, thereby realizing full-automatic cleaning of the dirt on the surface of the filter. Compared with the prior art, the utility model does not need manual cleaning of the filter, which is more convenient; by installing a collection box for collecting dust dropped when cleaning the filter, by setting a baffle and an electric push rod, the passage between the collection box and the shell can be closed when the device performs air purification work: cavity, to prevent the collected dust from affecting the normal purification work.

[0003] The prior art realizes the cleaning of the filter by vertically lifting the brush, but the vertical lifting of the brush easily causes the dust to rise with the brush and accumulate on the upper part of the brush, which is difficult to clean thoroughly. Moreover, after the brush contacts the filter, the dust is easily stuffed into the holes of the filter, causing the dust to enter the air purifier, resulting in poor cleaning effect. Therefore, an indoor air purifier with a self-cleaning function is needed to meet people's needs. Summary of the invention

[0004] The purpose of the utility model is to provide an indoor air purifier with a self-cleaning function, so as to solve the problem that the vertical lifting of the brush in the prior art proposed in the above-mentioned background technology easily causes dust to rise with the brush and accumulate on the upper part of the brush, making it difficult to clean thoroughly, and after the brush contacts the filter, it is easy to stuff dust into the holes of the filter, causing dust to enter the air purifier and resulting in poor cleaning effect.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 , an indoor air purifier with a self-cleaning function, comprising an air purifier housing 1, a motor 2 is arranged on the inner wall of the top end of the air purifier housing 1, a first gear 3 is arranged on the output shaft of the motor 2, a reciprocating screw rod 4 is arranged on the bottom end of the first gear 3, a reciprocating slider 5 is transmission-connected to the reciprocating screw rod 4, a connecting rod 6 is rotatably installed in one end of the reciprocating slider 5, a cleaning brush 7 is arranged on the connecting rod 6, a filter screen 8 is arranged in the air purifier housing 1, the cleaning brush 7 is in contact with one side of the filter screen 8, a second gear 9 is meshed with the first gear 3, a connecting shaft 10 is connected to the bottom end of the second gear 9, a first bevel gear 11 is connected to the bottom end of the connecting shaft 10, a second bevel gear 12 is vertically meshed with the first bevel gear 11, and a fan blade 13 is connected to one side of the second bevel gear 12.

[0024] When self-cleaning is required, the motor 2 is driven, and the motor 2 drives the first gear 3 to rotate, and the first gear 3 drives the reciprocating screw rod 4 to rotate, so that the reciprocating slider 5 drives the connecting rod 6 and the cleaning brush 7 to move. When the reciprocating slider 5 moves from bottom to top, the resistance between the cleaning brush 7 and the filter 8 causes the connecting rod 6 to drive the cleaning brush 7 to droop, thereby reducing the contact area between the cleaning brush 7 and the filter 8. At this time, the cleaning brush 7 cannot brush off the dust on the filter 8. When the reciprocating slider 5 moves from top to bottom, the drooping cleaning brush 7 is blocked by the filter 8, driving the connecting rod 6 to rotate upward to a horizontal position. The brush surface of the cleaning brush 7 is completely in contact with the filter 8, thereby scraping the dust on the filter 8 downwards. The motor 2 drives the first gear 3 to rotate, while the second gear 9 rotates. The first bevel gear 11 rotates through the connection of the connecting shaft 10. The first bevel gear 11 drives the second bevel gear 12 to rotate, so that the fan blades 13 rotate, thereby forming an outward exhaust effect inside the air purifier housing 1. At this time, negative pressure is formed at the filter 8, and the dust blocked in the holes of the filter 8 is discharged to the outside of the air purifier housing 1, effectively preventing dust from entering the inside of the air purifier when the cleaning brush 7 scrapes off the dust.

[0025] Specifically, in the present embodiment, a first partition 14 is horizontally arranged in the air purifier housing 1, the first partition 14 is located above the filter 8, the first gear 3 and the second gear 9 are both located above the first partition 14, the reciprocating screw rod 4 and the connecting shaft 10 are both rotatably installed in the first partition 14, and the first partition 14 provides positioning for the first gear 3 and the second gear 9, thereby ensuring the meshing between the first gear 3 and the second gear 9.

[0026] Specifically, in this embodiment, a ball screw hole 15 is opened on the reciprocating slider 5, and the reciprocating screw 4 is transmission-adapted in the ball screw hole 15, so that the unidirectional rotation of the reciprocating screw 4 realizes the reciprocating movement of the reciprocating slider 5.

[0027] Specifically, in this embodiment, a positioning rod 16 is provided on the bottom end of the first partition 14 , the positioning rod 16 is parallel to the reciprocating screw 4 , and the reciprocating slider 5 is slidably installed on the positioning rod 16 , thereby ensuring the stability of the reciprocating movement of the reciprocating slider 5 in the vertical direction.

[0028] Specifically, in the present embodiment, a rotating groove 17 is opened in one side of the reciprocating slider 5, the top inner wall of the rotating groove 17 is horizontal, and the bottom inner wall of the rotating groove 17 is inclined, so that when the reciprocating slider 5 moves downward, the connecting rod 6 is restricted by the top inner wall of the rotating groove 17, thereby realizing the horizontal state of the cleaning brush 7, and when the reciprocating slider 5 moves upward, the connecting rod 6 is restricted by the bottom inner wall of the rotating groove 17, thereby realizing the drooping state of the cleaning brush 7.

[0029] Specifically, in this embodiment, a second partition 18 is horizontally arranged in the air purifier housing 1, and the second partition 18 is located below the filter 8. A collection frame 19 is slidably installed between the second partition 18 and the bottom inner wall of the air purifier housing 1, and the collection frame 19 is convenient for collecting dust scraped by the cleaning brush 7.

[0030] Specifically, in the present embodiment, a cross bar 20 is provided between the inner walls at both ends of the air purifier housing 1, a positioning shaft 21 is rotatably installed in the cross bar 20, one end of the positioning shaft 21 is connected to the second bevel gear 12, and the other end of the positioning shaft 21 is connected to the fan blade 13, the cross bar 20 and the positioning shaft 21 provide positioning for the second bevel gear 12, and ensure the meshing between the second bevel gear 12 and the first bevel gear 11.
