[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a vacuum cleaner capable of self-cleaning dust. Background Art

[0002] With the development of technology, vacuum cleaners have become one of the essential household appliances in people's daily lives. The working principle of a vacuum cleaner is that through the high-speed rotation of a motor, air is inhaled from the suction inlet, creating a certain vacuum in the dust box. Dust enters the filter bag in the dust box through the floor brush, connecting pipe, handle, hose, and main suction pipe, thereby achieving cleaning. Moreover, the vacuum cleaner can be equipped with different suction heads to clean and remove dust from places that are not easy to clean, such as hair and the gaps of furniture, thus improving the indoor air quality and maintaining household hygiene. However, after the vacuum cleaner is used, the garbage and dust in the dust bucket need to be cleaned up to avoid dust accumulation in the filter component, which may lead to a deterioration in the suction effect of the vacuum cleaner.

[0003] Currently, a blowing dust channel is provided outside the filter component of the vacuum cleaner, and the fan component blows air into the blowing dust channel to clean the dust on the inner wall of the dust cup body and the outside of the filter component, thereby achieving self-cleaning. However, the current vacuum cleaner can only clean the dust on the surface of the filter component, and the dust contaminated on the inner side of the filter component cannot be cleaned, so there will be a phenomenon of dust accumulation, which gradually deteriorates the suction effect of the vacuum cleaner.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Referring to Figures 1 to 4 , an embodiment of the present invention provides a self-cleaning dust collector, which includes an outer shell 1, a filter assembly 2, a motor assembly 3 and a base station 4. The base station 4 is detachably connected to the outer shell 1. The filter assembly 2 is arranged inside the outer shell 1. The motor assembly 3 is rotatably arranged inside the outer shell 1. The motor assembly 3 has an air inlet 311 and an air outlet 312. The filter assembly 2 has a blowing channel 21 and a ventilation port 22 that are communicated with each other. The outer shell 1 has a dust removal port 13. When the self-cleaning dust collector is in the dust suction mode, the base station 4 is detached from the outer shell 1, the air inlet 311 is communicated with the ventilation port 22, the air outlet 312 is used for communicating with the outside, and the dust removal port 13 is closed; when the self-cleaning dust collector is in the self-dust collection mode, the base station 4 is connected to the outer shell 1, the base station 4 drives the motor assembly 3 to rotate, the positions of the air inlet 311 and the air outlet 312 change, the air inlet 311 is used for communicating with the outside, the air outlet 312 is communicated with the blowing channel 21 and the ventilation port 22, the dust removal port 13 is opened and communicated with the base station 4, so that the dust contaminated on the filter assembly 2 is blown into the base station 4 and collected, avoiding environmental pollution.

[0028] Referring to Figure 2 , the filter assembly 2 includes a filter element 23 and a filter element bracket 24. The filter element bracket 24 is arranged inside the outer shell 1. The filter element 23 is arranged inside the filter element bracket 24. There is a gap between the filter element 23 and the filter element bracket 24, which is the blowing channel 21. The ventilation port 22 is located on the filter element 23.

[0029] Referring to Figure 2 and Figure 4, a connection bracket 11 and a mounting base 12 are arranged inside the housing 1. One end of the connection bracket 11 is connected to the mounting base 12, and the other end of the connection bracket 11 is connected to the filter assembly 2. The connection bracket 11 has a communication cavity 111 with openings at both ends and an air cavity 112 with openings at both ends. Among them, the lower end of the communication cavity 111 is communicated with the ventilation port 22 of the filter assembly 2, and the lower end of the air cavity 112 is communicated with the blowing channel 21. The lower end of the housing 1 has a dust suction port 14. When the self-cleaning dust collector is in the dust suction mode, the upper end of the communication cavity 111 is communicated with the air inlet 311. After the gas enters through the dust suction port 14, it successively passes through the filter assembly 2, the communication cavity 111 and flows out through the air outlet 312, so as to realize the circulation of the gas. The upper end of the air cavity 112 is blocked, so as to prevent dust from being directly discharged without passing through the filter assembly 2; when the self-cleaning dust collector is in the self-collecting dust mode, the upper end of the communication cavity 111 and the upper end of the air cavity 112 are both communicated with the air outlet 312. The gas enters through the air inlet 311, successively passes through the communication cavity 111, the inside of the filter assembly 2 and the blowing channel 21, and flows out through the dust removal port 13. At the same time, the gas drives the dust on the filter assembly 2 to move, and the dust adhering to the inside and outside of the filter assembly 2 falls at the same time and falls into the base station 4 through the dust removal port 13, so as to realize self-collecting dust, avoid polluting the environment, and at the same time make the dust on the filter assembly 2 less, and avoid affecting the performance of the self-cleaning dust collector.

[0030] Refer to Figure 2 and Figure 4 , the motor assembly 3 includes a housing 31, a motor group 32, a baffle 33 and a driven toothed plate 34. The housing 31 is rotatably arranged in the mounting base 12. The air inlet 311 and the air outlet 312 are both located on the housing 31. The motor group 32 and the baffle 33 are both arranged inside the housing 31. The driven toothed plate 34 is arranged on the housing 31. The housing 31 is driven to rotate by the rotation of the driven toothed plate 34, so that the self-cleaning dust collector can be switched between the dust suction mode and the self-collecting dust mode. Among them, the motor group 32 drives the blades to rotate at a high speed through the motor, generating an air negative pressure inside the housing 31 and forming a negative pressure difference with the outside atmosphere, so as to suck dust; when the self-cleaning dust collector is in the dust suction mode, the baffle 33 covers the upper end of the air cavity 112, and the gas can only enter the communication cavity 111 after being filtered by the filter assembly 2; when the self-cleaning dust collector is in the self-collecting dust mode, the driven toothed plate 34 rotates, so that the baffle 33 moves away from the upper end of the air cavity 112, so that the air outlet 312 is communicated with the air cavity 112 and the communication cavity 111, so that the gas drives the dust inside and outside the filter assembly 2 to move into the base station 4 for recovery at the same time.

[0031] Refer to Figure 2 , the air outlet 312 includes a first air outlet 313 and a second air outlet 314. The first air outlet 313 is communicated with the air cavity 112, and the second air outlet 314 is communicated with the communication cavity 111.

[0032] Referring to Figure 2 and Figure 4 Figure 4 , the self - cleaning vacuum cleaner further includes a driving assembly 5. The driving assembly 5 includes a driving member 51, a gear set 52, and a spring 54. A tooth groove 53 is formed on the driving member 51. The tooth groove 53 meshes with the gear set 52. The gear set 52 is rotatably disposed in the housing 1. The driven tooth plate 34 meshes with the gear set 52. The spring 54 is disposed in the housing 1. The upper end of the driving member 51 abuts against the spring 54. When the driving member 51 moves, it will drive the gear set 52 to rotate. The rotation of the gear set 52 will drive the driven tooth plate 34 to rotate, so that the motor assembly 3 rotates, so as to change the positions of the air inlet 311 and the air outlet 312. A bent reset baffle is provided on the driving member 51. When the self - cleaning vacuum cleaner is in the dust - suction mode, the reset baffle abuts against the gear set 52. Therefore, when the self - cleaning vacuum cleaner is switched from the self - dust - collecting mode to the dust - suction mode, the driving member 51 is prevented from excessive displacement through the reset baffle. In the embodiment of the present application, the gear set 52 includes two large gears and two small gears that are sequentially meshed. Among them, one small gear meshes with the driven tooth plate 34, and one large gear meshes with the tooth groove 53.

[0033] Referring to Figure 1 and Figure 2 Figure 2 , the base station 4 includes a body main body 43 and a triggering member 42. The triggering member 42 is connected to the body main body 43. The body main body 43 is detachably connected to the housing 1. When the self - cleaning vacuum cleaner is in the self - dust - collecting mode, the base station 4 is connected to the housing 1. The triggering member 42 abuts against the lower end of the driving member 51. The triggering member 42 pushes the driving member 51 to move upward. The spring 54 is compressed by force. The driving member 51 drives the gear set 52 to rotate. The gear set 52 drives the driven tooth plate 34 to rotate, so as to change the positions of the air inlet 311 and the air outlet 312. When the self - cleaning vacuum cleaner is in the dust - suction mode, the base station 4 is detached from the housing 1. The driving member 51 is reset under the elastic action of the spring 54. The driving member 51 drives the gear set 52 to rotate in the reverse direction. The gear set 52 drives the driven tooth plate 34 to reset. The motor assembly 3 also resets accordingly, so that the positions of the air inlet 311 and the air outlet 312 return to their original positions.

[0034] Referring to Figure 1 and Figure 2 Figure 2 , a dust bag assembly 41 is provided on the body main body 43. The dust bag assembly 41 is communicated with the dust removal port 13. A sealing plate 15 is rotatably provided at the dust removal port 13. In the dust - suction mode, the sealing plate 15 seals the dust removal port 13. In the self - dust - collecting mode, the sealing plate 15 rotates, so that the dust removal port 13 is communicated with the dust bag assembly 41.
