The left side plate, the left bracket, the baffle, the right bracket on the top of the indoor unit of the air conditioner and the right side plate on the top of the indoor unit of the air conditioner together constitute the top appearance surface of the indoor unit of the air conditioner.

[0003] However, as the consumer market has higher and higher requirements for the performance of the whole machine product, the appearance surface of the top composed of the left side plate, the left bracket, the baffle, the right bracket and the right side plate cannot effectively utilize the space of the indoor unit of the air conditioner, which will cause the overall length of the indoor unit of the air conditioner to be too long, affecting the installation applicability of the product, or the length of the air inlet is too small to meet the air inlet demand. Utility Model Content

[0004] The embodiments of this application provide an indoor unit of an air conditioner to at least solve the technical problem that the appearance surface of the top composed of the left side plate, the left bracket, the baffle, the right bracket and the right side plate cannot effectively utilize the space of the indoor unit of the air conditioner, which will cause the overall length of the indoor unit of the air conditioner to be too long, affecting the installation applicability of the product, or the length of the air inlet is too small to meet the air inlet demand.

[0005] According to the first aspect of the embodiments of this application, an indoor unit housing of an air conditioner is provided, and its top has a first side plate, an air inlet and a second side plate arranged in sequence along its length direction;

[0006] A baffle assembly, the baffle assembly is arranged at the air inlet, and the baffle assembly includes: a first bracket and a second bracket oppositely arranged in the air inlet along the length direction of the housing, a plurality of baffles rotatably arranged between the first bracket and the second bracket, and a driving motor arranged below the first bracket, the driving motor can drive the plurality of baffles to rotate between the first bracket and the second bracket to close or open the air inlet;

[0007] Wherein, the second bracket is arranged below the second side plate, and the first side plate, the first bracket, the plurality of baffles and the second side plate arranged in sequence along the length direction of the housing form the appearance surface of the top of the housing.

[0008] By adopting this embodiment, the appearance surface can be formed only by the first side plate, the first bracket, the baffle and the second side plate, which can reduce the space required by the second bracket and the second side plate together. Without increasing the length of the air conditioner indoor unit, the length of the air inlet can be increased, the air intake volume can be increased, and the overall performance of the unit can be improved. Moreover, the splicing seam between the second bracket and the second side plate can be removed, making the air conditioner indoor unit more compact and improving the appearance of the air conditioner indoor unit.

[0009] In an alternative implementation manner of the embodiment of the present application in combination with the first aspect, the first bracket has: a first plate body extending along the length direction of the housing and a second plate body extending along the height direction of the housing, and the first plate body is arranged on the top of the second plate body;

[0010] The second bracket has: a third plate body extending along the length direction of the housing and a fourth plate body extending along the height direction of the housing, and the third plate body is arranged at the bottom of the fourth plate body;

[0011] Wherein, the plurality of baffles are rotatably arranged between the second plate body and the fourth plate body;

[0012] The first plate body and the first side plate are spliced to form the appearance surface, and the third plate body is arranged below the second side plate.

[0013] In an alternative implementation manner of the embodiment of the present application in combination with the first aspect, an installation bracket is arranged in the housing, at least part of the installation bracket is located below the second side plate, and the second bracket is located between the installation bracket and the second side plate;

[0014] Wherein, the bottom of the third plate body is abutted and arranged on the upper side of the installation bracket, and the top of the fourth plate body is abutted and arranged on the lower side of the second side plate.

[0015] In an alternative implementation manner of the embodiment of the present application in combination with the first aspect, the installation bracket is provided with a first limiting rib and a second limiting rib below the second side plate, and the first limiting rib and the second limiting rib are arranged opposite to each other along the length direction of the housing;

[0016] One side of the third plate body has a limiting hole corresponding to the position and adapted to the shape of the first limiting rib, so that the first limiting rib is inserted into the limiting hole;

[0017] The other side of the third plate body abuts against the side of the second limiting rib facing the first limiting rib.

[0018] By adopting this implementation manner, the stability of the entire second bracket can be ensured through the abutting fit between the third plate body and the mounting bracket. The top of the fourth plate body abuts against the second side plate, and it can also play a certain supporting role for the second side plate.

[0019] Optionally, in an implementation manner of this embodiment, the mounting bracket is provided with a first limiting rib and a second limiting rib below the second side plate, and the first limiting rib and the second limiting rib are arranged oppositely along the length direction of the housing;

[0020] Combined with the first aspect, in an optional implementation manner of the embodiment of the present application, one side of the third plate body has a limiting hole corresponding to the position and adapted to the shape of the first limiting rib, so that the first limiting rib is inserted into the limiting hole;

[0021] The other side of the third plate body abuts against the side of the second limiting rib facing the first limiting rib.

[0022] By adopting this implementation manner, the positioning and limiting effects on the second bracket can be achieved. While enabling the second bracket to be accurately installed, it can prevent the second bracket from moving when the baffle rotates.

[0023] Combined with the first aspect, in an optional implementation manner of the embodiment of the present application, the mounting bracket is provided with a first limiting rib and a second limiting rib below the second side plate, and both the first limiting rib and the second limiting rib protrude along the height direction of the housing and are arranged at a distance in the length direction of the housing;

[0024] One side of the third plate body in the length direction of the housing has a limiting hole corresponding to the position and adapted to the shape of the first limiting rib, so that the first limiting rib is inserted into the limiting hole;

[0025] The other side of the third plate body in the length direction of the housing abuts against the second limiting rib.

[0026] Combined with the first aspect, in an optional implementation manner of the embodiment of the present application, the upper side of the mounting bracket has a plurality of support ribs, and the support ribs are located at the bottom of the third plate body.

[0027] By adopting this implementation manner, the contact form of surface to surface can be changed to line to surface contact. While ensuring the support for the third plate body, the contact surface can be reduced, and when the baffle rotates and drives the second bracket to move, it can avoid generating a large noise, which affects the user experience.

[0028] In combination with the first aspect, in an alternative implementation of the embodiment of the present application, the second plate body has a plurality of first mounting holes extending along the length direction of the housing, and the fourth plate body has a plurality of second mounting holes extending along the length direction of the housing and corresponding to the first mounting holes;

[0029] Each baffle is provided with a rotating shaft extending along the length direction of the housing. Both ends of each rotating shaft are respectively arranged in the corresponding first mounting hole and the second mounting hole. A connecting rod is connected to one side of each rotating shaft where the first mounting hole is located. The connecting rod is in transmission cooperation with the driving motor, so that the driving motor can drive each baffle to flip together through the connecting rod.

[0030] In combination with the first aspect, in an alternative implementation of the embodiment of the present application, the second plate body has a plurality of first mounting holes penetrating through its body along the length direction of the housing, and the fourth plate body has a plurality of second mounting holes penetrating through its body along the length direction of the housing. A plurality of the second mounting holes correspond to a plurality of the first mounting holes one by one;

[0031] Each baffle is provided with a rotating shaft extending along the length direction of the housing. Both ends of each rotating shaft are respectively arranged in the corresponding first mounting hole and the second mounting hole. A connecting rod is connected to one side of each rotating shaft where the first mounting hole is located. The connecting rod is in transmission cooperation with the driving motor, so that the driving motor can drive each baffle to flip together through the connecting rod.

[0032] In combination with the first aspect, in an alternative implementation of the embodiment of the present application, the axis of the rotating shaft has a preset distance from the center line of the baffle along the width direction of the housing, and the rotating shaft is located between the center line of the baffle and the rear side wall of the baffle;

[0033] Wherein, the preset distance is 2 mm to 3 mm.

[0034] Adopting this implementation method can make the center of gravity of the baffle move forward. When controlling the baffle to close the air inlet, the baffle can be blocked to a certain extent by means of its own gravity, making the blocking effect of the baffle better.

[0035] In combination with the first aspect, in an alternative implementation of the embodiment of the present application, the width of the baffle along the housing direction is 25 mm to 30 mm.

[0036] Adopting this implementation method can reduce the weight of each baffle on the premise that the width and length of the baffle remain unchanged, and thus can improve the reliability of the rotating baffle.

[0037] In an alternative implementation manner of the embodiment of the present application in combination with the first aspect, the air conditioner indoor unit further includes:

[0038] A filter screen, disposed below the baffle, for filtering the air flow entering the housing through the air inlet;

[0039] A dust removal brush, disposed between the filter screen and the baffle, the dust removal brush being located in front of the baffle and the filter screen, and the dust removal brush being capable of reciprocating along the length direction of the housing on the surface of the filter screen;

[0040] The mounting bracket further has a dust collection groove below the second side plate, and the dust collection groove is used for collecting the dust swept off by the dust removal brush;

[0041] A dust collection box, disposed between the fourth plate body and the second side plate, the dust collection box is connected with a suction pipe, the suction port of the suction pipe faces the dust collection groove, and the dust collection box is used for collecting the dust in the dust collection groove.

[0042] With this implementation manner, the filter screen can be cleaned by the dust removal brush that can reciprocate below the baffle and above the filter screen. Specifically, the dust removal brush can be a brush that can rotate under the drive of a rotation drive motor and translate through a transmission structure under the drive of a movement drive motor. When the dust removal brush moves from the first bracket to the second bracket, it contacts the surface of the filter screen and sweeps the dust on the filter screen into the dust collection groove. Then, when it moves back from the second bracket to the first bracket and resets, it can rotate a certain angle and does not contact the filter screen. Repeating this process, most of the dust on the surface of the filter screen is swept into the dust collection groove, and then the dust in the dust collection groove is sucked away by the relatively large-volume and detachable dust collection box and stored in the dust collection box.

[0043] In an alternative implementation manner of the embodiment of the present application in combination with the first aspect, a controller is used to control the drive motor to drive the baffle to swing back and forth at a preset angle at a preset speed to shake off the dust on the baffle;

[0044] Wherein, the preset speed is 30° / s to 60° / s, and the preset angle is 30° to 60°.

[0045] With this implementation manner, the baffle can be controlled by the controller to shake, that is, to quickly reciprocate and shake at a preset angle at a preset speed, so that the dust can be shaken off. After the shaken-off dust falls onto the filter screen, it can be cleaned by the dust removal brush and finally collected into the dust collection box.

[0046] According to the second aspect of the embodiment of the present application, an air conditioner is provided, including the aforementioned air conditioner indoor unit.

[0047] According to the air conditioner indoor unit of the embodiment of the present utility model, the second bracket without a driving motor arranged below is arranged below the second side plate, so that the top appearance surface of the air conditioner indoor unit is no longer jointly constituted by the first side plate, the first bracket, the baffle, the second bracket and the second side plate, but only the first side plate, the first bracket, the baffle and the second side plate form the appearance surface. This can reduce the space occupied jointly by the second bracket and the second side plate, increase the length of the air inlet without increasing the length of the air conditioner indoor unit, improve the air intake volume, improve the overall performance of the unit, and can remove the splicing seam between the second bracket and the second side plate, making the air conditioner indoor unit more compact and improving the appearance degree of the air conditioner indoor unit.

[0066] The existing dust-proof solution for air conditioners is to design an air inlet baffle at the air inlet position of the indoor unit of the air conditioner, and the baffle assembly is composed of several baffles, a left bracket, a right bracket, a connecting rod, a motor, etc. The motor is arranged below the right bracket and drives the baffle to flip through the connecting rod, and the left side plate, the left bracket, the baffle, the right bracket on the top of the indoor unit of the air conditioner and the right side plate on the top of the indoor unit of the air conditioner together constitute the top appearance surface of the indoor unit of the air conditioner.

[0067] However, as the consumer market has increasingly higher requirements for the performance of the whole machine products, the appearance surface of the top formed by the left side plate, the left bracket, the baffle, the right bracket and the right side plate cannot effectively utilize the space of the air conditioner indoor unit, which will cause the overall length of the air conditioner indoor unit to be too long, affecting the installation applicability of the product, or the length of the air inlet is too small to meet the air inlet demand.

[0068] Based on this, as Figures 1-7 shown, the air conditioner indoor unit according to an embodiment of the present invention includes: a housing 1, the top of which is provided with a first side plate 11, an air inlet 12 and a second side plate 13 arranged in sequence along its length direction;

[0069] a baffle 23 assembly 2, the baffle 23 assembly 2 is arranged at the air inlet 12, and the baffle 23 assembly 2 includes: a first bracket 21 and a second bracket 22 oppositely arranged in the air inlet 12 along the length direction of the housing 1, a plurality of baffles 23 rotatably arranged between the first bracket 21 and the second bracket 22, and a driving motor 24 arranged below the first bracket 21, and the driving motor 24 can drive the plurality of baffles 23 to rotate between the first bracket 21 and the second bracket 22 to close or open the air inlet 12;

[0070] Wherein, the second bracket 22 is arranged below the second side plate 13, and the first side plate 11, the first bracket 21, the plurality of baffles 23 and the second side plate 13 arranged in sequence along the length direction of the housing 1 form the appearance surface of the top of the housing 1.

[0071] Specifically, the air conditioner indoor unit can be a wall-mounted air conditioner indoor unit, and the housing 1 can be hung on the wall. When the user faces the housing 1 directly, the left and right directions of the user are the length direction of the housing 1, the up and down directions are the height direction of the housing 1, and the front and back directions are the width direction of the housing 1.

[0072] Both the first bracket 21 and the second bracket 22 can be an "L"-shaped plate body. The vertical plates of the first bracket 21 and the second bracket 22 are oppositely arranged and can be used to assemble the baffle 23. However, the horizontal plate of the first bracket 21 is butted against the first side plate 11, and the driving motor 24 can be accommodated below the first bracket 21 and the first side plate 11. The side where the driving motor 24 does not need to be arranged is the side where the second side plate 13 and the second bracket 22 are located. The horizontal plate of the second bracket 22 is opposite to the second side plate 13 and is located below the second side plate 13. The vertical plate of the second bracket 22 is also arranged below the second side plate 13, and its top can be abutted against the second side plate 13. The whole second bracket 22 is arranged below the second side plate 13, and the second side plate 13 is directly butted against the baffle 23 at the top of the housing 1.

[0073] Since the second bracket 22 is entirely disposed below the second side plate 13, the second bracket 22 no longer occupies the space along the length direction at the top of the housing 1, which can reduce the required length of the housing 1. The top appearance surface of the housing 1 changes from the first side plate 11 docking with the first bracket 21, the first bracket 21 docking with the baffle 23, the baffle 23 docking with the second bracket 22, and the second bracket 22 docking with the second side plate 13 in the prior art to the first side plate 11 docking with the first bracket 21, the first bracket 21 docking with the baffle 23, and the baffle 23 directly docking with the second side plate 13. On the premise that the overall length of the housing 1 remains unchanged, the length of the air inlet 12 can be increased to improve the air volume, or on the premise that the length of the air inlet 12 remains unchanged, the overall length of the unit can be reduced to make the air conditioner indoor unit more compact, or both can be achieved.

[0074] Moreover, since the baffle 23 can directly dock with the second side plate 13, it can not only reduce the requirement of the housing 1 for length space, but also reduce the seams, making the appearance more flat and integrated, more beautiful, and improving the user's perception.

[0075] The drive motor 24 can be in transmission cooperation with a plurality of baffles 23 through a connecting rod, so that when the drive motor 24 rotates, it can drive a plurality of baffles 23 to flip together, thereby opening or closing the air inlet 12.

[0076] In the air conditioner indoor unit according to an embodiment of the present invention, the second bracket 22 without the drive motor 24 disposed below is disposed below the second side plate 13, so that the top appearance surface of the air conditioner indoor unit is no longer jointly constituted by the first side plate 11, the first bracket 21, the baffle 23, the second bracket 22, and the second side plate 13, but only the first side plate 11, the first bracket 21, the baffle 23, and the second side plate 13 form the appearance surface. It can reduce the space jointly occupied by the second bracket 22 and the second side plate 13, and can increase the length of the air inlet 12 without increasing the length of the air conditioner indoor unit, improve the air intake volume, improve the overall performance of the unit, and can remove the splicing seam between the second bracket 22 and the second side plate 13, making the air conditioner indoor unit more compact and improving the appearance degree of the air conditioner indoor unit.

[0077] Optionally, in an implementation manner of this embodiment, the first bracket 21 has a first plate body 211 extending along the length direction of the housing 1 and a second plate body 212 extending along the height direction of the housing 1, and the first plate body 211 is disposed on the top of the second plate body 212;

[0078] The second bracket 22 has a third plate body 221 extending along the length direction of the housing 1 and a fourth plate body 222 extending along the height direction of the housing 1, and the third plate body 221 is disposed at the bottom of the fourth plate body 222;

[0079] Among them, the multiple baffles 23 are all rotatably arranged between the second plate body 212 and the fourth plate body 222;

[0080] The first plate body 211 and the first side plate 11 are spliced to form the appearance surface, and the third plate body 221 is arranged below the second side plate 13.

[0081] Specifically, both the first bracket 21 and the second bracket 22 can be composed of two spliced plate bodies or integrally formed. The second plate body 212 and the fourth plate body 222 both extend along the height direction of the housing 1, which can provide a fulcrum for the baffle 23. The baffle 23 can be rotatably connected to the second plate body 212 and the fourth plate body 222 respectively by rotation. The first plate body 211 is located at the top of the fourth plate body 222. After the first plate body 211 is butted against the first side plate 11, the lower part of the first plate body 211 can be used to accommodate the drive motor 24, and the drive motor 24 can drive the baffle 23 to flip.

[0082] Optionally, in an implementation manner of this embodiment, an installation bracket 3 is arranged in the housing 1, and at least part of the installation bracket 3 is located below the second side plate 13, and the second bracket 22 is located between the installation bracket 3 and the second side plate 13;

[0083] Among them, the bottom of the third plate body 221 is abutted and arranged on the upper side of the installation bracket 3, and the top of the fourth plate body 222 is abutted and arranged on the lower side of the second side plate 13.

[0084] Specifically, the third plate body 221 extends along the length direction of the housing 1. The bottom of the third plate body 221 can be integrally abutted on the installation bracket 3 and can be fitted with the installation bracket 3. The overall stability of the second bracket 22 can be ensured through the abutting cooperation between the third plate body 221 and the installation bracket 3. The top of the fourth plate body 222 abuts against the second side plate 13 and can also play a certain supporting role for the second side plate 13.

[0085] Optionally, in an implementation manner of this embodiment, the installation bracket 3 is provided with a first limiting rib 31 and a second limiting rib 32 below the second side plate 13. The first limiting rib 31 and the second limiting rib 32 are oppositely arranged along the length direction of the housing 1. Among them, both the first limiting rib 31 and the second limiting rib 32 protrude along the height direction of the housing and are arranged at intervals in the length direction of the housing;

[0086] One side of the third plate body 221 has a 2211 corresponding to the position and shape of the first limiting rib 31, so that the first limiting rib 31 is inserted into the 2211;

[0087] The other side of the third plate body 221 abuts against the side of the second limiting rib 32 facing the first limiting rib 31.

[0088] Specifically, through the cooperation of the first limiting rib 31 and 2211, and through the cooperation of the second limiting rib 32 and the side wall of the third plate body 221, the second bracket 22 can be positioned and limited, so that the second bracket 22 can be accurately positioned during installation, and at the same time, the second bracket 22 can be prevented from moving when the baffle 23 rotates.

[0089] Third limiting ribs can also be provided at both ends of the second bracket 22, and the third limiting ribs cooperate with the corresponding positions of the mounting bracket 3, so that the second bracket 22 can be quickly positioned during installation, facilitating assembly.

[0090] Optionally, in an implementation manner of this embodiment, the upper side of the mounting bracket 3 has a plurality of support ribs 33, and the support ribs 33 are located at the bottom of the third plate body 221.

[0091] Specifically, the mounting bracket 3 can also contact the third plate body 221 through the support ribs 33, which can change the contact form from surface-to-surface contact to line-to-surface contact. While ensuring the support for the third plate body 221, the contact surface can be reduced, avoiding the generation of excessive noise when the baffle 23 rotates and drives the second bracket 22 to move, which affects the user experience.

[0092] Optionally, in an implementation manner of this embodiment, the second plate body 212 has a plurality of first mounting holes 2121 extending along the length direction of the housing 1, and the first mounting holes 2121 penetrate through the body of the first plate body 212; the fourth plate body 222 has a plurality of second mounting holes 2221 extending along the length direction of the housing 1 and corresponding to the first mounting holes 2121, wherein the second mounting holes 2221 penetrate through the body of the fourth plate body 222;

[0093] Each baffle 23 is provided with a rotating shaft 231 extending along the length direction of the housing 1. Both ends of each rotating shaft 231 are respectively arranged in the corresponding first mounting holes 2121 and the second mounting holes 2221. A connecting rod is connected to one side of each rotating shaft 231 where the first mounting holes 2121 are located, and the connecting rod is in transmission cooperation with the driving motor 24, so that the driving motor 24 can drive each baffle 23 to flip together through the connecting rod.

[0094] Specifically, each baffle 23 has a rotating shaft 231. The rotating shaft 231 cooperates with the second plate body 212 and the fourth plate body 222 on both sides for rotation. Corresponding first mounting holes 2121 and second mounting holes 2221 can be provided in the second plate body 212 and the fourth plate body 222 to provide a rotation fulcrum for the rotating shaft 231, enabling the baffle 23 to rotate between the first mounting hole 2121 and the second mounting hole 2221 to open or close the air inlet 12.

[0095] Optionally, in an implementation manner of this embodiment, the axis of the rotating shaft 231 has a preset distance from the center line of the baffle 23 in the width direction of the housing 1, and the rotating shaft 231 is located between the center line of the baffle 23 and the rear side wall of the baffle 23;

[0096] Wherein, the preset distance is 2 mm to 3 mm.

[0097] Specifically, as Figure 7 shown, the rotating shaft 231 of each baffle 23 is not arranged at the center position of the baffle 23 in the width direction of the housing 1. The baffle 23 rotates around the rotating shaft 231, that is, the rotation axis of the baffle 23 deviates 2 mm to 3 mm backward from the baffle 23, which can make the center of gravity of the baffle 23 move forward. When controlling the baffle 23 to close the air inlet 12, the baffle 23 can be blocked by means of its own gravity to a certain extent, making the blocking effect of the baffle 23 better.

[0098] A corresponding latching plate can be provided on the front side of each baffle 23. On the one hand, the latching plate can limit the baffle 23, so that the baffle 23 will not rotate excessively and generate gaps when blocking the air inlet 12. On the other hand, the latching plate can cooperate with the gravity of the baffle 23 itself, so that the baffle 23 contacts the latching plate under the action of its own gravity to close the air inlet 12.

[0099] Optionally, in an implementation manner of this embodiment, the width of the baffle 23 in the direction of the housing 1 is 25 mm to 30 mm.

[0100] Specifically, the width of each baffle 23 is limited so that the width of each baffle 23 is between 25 mm and 30 mm. Preferably, it can be 28 mm. Due to the limitation of the length of the air inlet 12 and the normal function of blocking dust, on the premise that the width and length of the baffle 23 remain unchanged, the weight of each baffle 23 can be reduced, and thus the reliability of the rotating baffle 23 can be improved.

[0101] Optionally, in an implementation manner of this embodiment, the air conditioner indoor unit further includes:

[0102] A filter screen 4, arranged below the baffle 23, for filtering the air flow entering the housing through the air inlet 12;

[0103] The dust removal brush 5 is arranged between the filter net 4 and the baffle 23. The dust removal brush 5 is located in front of the baffle 23 and the filter net 4, and the dust removal brush 5 can reciprocate along the length direction of the housing 1 on the surface of the filter net 4;

[0104] The mounting bracket 3 further has a dust collection groove 34 below the second side plate 13. The dust collection groove 34 is used to collect the dust swept off by the dust removal brush 5;

[0105] The dust collection box 6 is arranged between the fourth plate body 222 and the second side plate 13. The dust collection box 6 is connected with a suction pipe 61. The suction port of the suction pipe 61 faces the dust collection groove 34. The dust collection box 6 is used to collect the dust in the dust collection groove 34.

[0106] Specifically, since the second bracket 22 is arranged below the second side plate 13, there is still a certain space between the second bracket 22 and the second side plate 13. The dust collection box 6 can be arranged in this space to collect dust through the dust collection box 6, avoiding too much dust on the filter net 4, affecting the air passing effect of the filter net 4, resulting in a decrease in the air volume of the air inlet 12 and affecting the performance of the air conditioner.

[0107] The filter net 4 can be cleaned by the dust removal brush 5 that can reciprocate below the baffle 23 and above the filter net 4. Specifically, the dust removal brush 5 can be a brush that can rotate under the drive of the rotation drive motor 24 and translate through the transmission structure under the drive of the movement drive motor 24. When the dust removal brush 5 moves from the first bracket 21 to the second bracket 22, it contacts the surface of the filter net 4 and sweeps the dust on the filter net 4 into the dust collection groove 34. Then when it moves back from the second bracket 22 to the first bracket 21 to reset, it can rotate a certain angle and does not contact the filter net 4. Repeating this process, most of the dust on the surface of the filter net 4 is swept into the dust collection groove 34, and then the dust in the dust collection groove 34 is sucked away by the relatively large-volume and detachable dust collection box 6, and the dust is stored in the dust collection box 6.

[0108] Optionally, in an implementation manner of this embodiment, the controller is used to control the drive motor 24 to drive the baffle 23 to swing reciprocally at a preset angle at a preset speed to shake off the dust on the baffle 23;

[0109] Wherein, the preset speed is 30° / s to 60° / s, and the preset angle is 30° to 60°.

[0110] Specifically, during long-term use, a certain amount of dust will also accumulate on the baffle 23. The controller can be used to control the baffle 23 to vibrate, that is, to perform rapid reciprocating vibrations at a preset speed and a preset angle, so that the dust can be shaken off. After the shaken-off dust falls onto the filter net 4, it can be cleaned by the dust removal brush 5 and finally collected in the dust collection box 6.
