Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a dust-gas separation device and a cleaning device. Background Art

[0002] Cleaning devices such as mite removers and vacuum cleaners are emerging household cleaning products at present. Usually, an adsorption force is generated by a vacuum pump to suck dirt such as dust on the surface to be cleaned, and then a dust-gas separation device is used to separate dust from the airflow carrying dust and other dirt, so as to filter and collect the dust. Finally, the relatively clean airflow after filtration is released into the environment, thereby achieving the cleaning effect.

[0003] In the dust cup of the dust-gas separation device in the related art, a cyclone separation chamber is provided, and the centrifugal force generated by the rotation of the airflow is used to separate and collect dust. In this process, the dust will collide with the inner wall and the filter screen of the cyclone separation chamber and adhere to them, which is not convenient for cleaning. After long-term use, it will cause internal pollution of the cyclone separation chamber, affect the subsequent use of users, and even breed bacteria. In addition, the dust adhering to the filter screen is also likely to cause the filter screen to be blocked, affecting the filtering effect. Summary of the Invention

[0004] In view of this, the present invention provides a dust-gas separation device and a cleaning device to solve the problem that the inner wall and the filter screen of the cyclone separation chamber of the dust-gas separation device in the prior art are easily adhered with dust and are not convenient for cleaning.

[0005] In a first aspect, the present invention provides a dust-gas separation device, including: A dust cup having a cyclone separation chamber; A filter assembly disposed in the cyclone separation chamber for filtering the airflow; A cleaning assembly rotatably disposed between the filter assembly and the cyclone separation chamber. The cleaning assembly is in contact and cooperation with the outer wall of the filter assembly and the inner wall of the cyclone separation chamber, and is used to clean the dust on the filter assembly and the cyclone separation chamber when driven to rotate; A cyclone air duct is formed between the outer circumference of the filter assembly and the inner circumference of the cyclone separation chamber. The cleaning assembly includes: A cleaning bracket including a scraping plate adapted to extend into the cyclone air duct; A dust cleaning member. The scraping plate has a first side close to the inner peripheral wall of the cyclone separation chamber and a second side close to the outer peripheral wall of the filter assembly; The dust cleaning member includes a first dust cleaning portion disposed on the first side of the scraping plate and a second dust cleaning portion disposed on the second side of the scraping plate. The first dust cleaning portion is adapted to contact the inner peripheral wall of the cyclone separation chamber, and the second dust cleaning portion is adapted to contact the outer peripheral wall of the filter assembly.

[0006] Beneficial effects: By utilizing the rotation of the cleaning component, 360-degree omnidirectional and dead-angle-free cleaning of the filter component and the cyclone separation chamber can be achieved, with better cleaning effect, higher efficiency, and the cleaning component does not need to be arranged around the entire circumference, occupying less space and being convenient for installation and layout. When the dust-gas separation device works, external air enters the cyclone separation chamber, and the airflow rotates in the cyclone separation chamber to drive the cleaning component to rotate. Since the cleaning component is in contact and cooperation with the outer wall of the filter component and the inner wall of the cyclone separation chamber, the rotating cleaning component can simultaneously clean the dust on the filter component and the inner wall of the cyclone separation chamber, avoiding the problems of internal pollution and bacteria breeding in the dust cup caused by long-term dust accumulation on the filter component and the cyclone separation chamber. Further, the rotating cleaning component can simultaneously clean the dust on the filter component and the inner wall of the cyclone separation chamber, further improving the dust cleaning efficiency and effect, keeping the cup wall of the cyclone separation chamber and the filter component clean and hygienic. Moreover, since the cyclone separation chamber and the filter screen component are cleaned simultaneously by the same cleaning component, it can also reduce the user's maintenance workload, simplify the structure, save resources, and provide a better user experience.

[0007] Further, the dust cleaning part includes a first dust cleaning part arranged on the side of the scraping plate close to the inner peripheral wall of the cyclone separation chamber and a second dust cleaning part close to the outer peripheral wall side of the filter component. The first dust cleaning part is in contact with the inner peripheral wall of the cyclone separation chamber, and the second dust cleaning part is in contact with the outer peripheral wall of the filter component. Thus, when the cleaning component is driven to rotate by the airflow, the first dust cleaning part can clean the dust on the entire inner peripheral wall of the cyclone separation chamber, and the second dust cleaning part can clean the dust on the entire outer peripheral wall of the filter component, realizing the simultaneous cleaning of the dust in the cyclone separation chamber and the filter component, with higher dust cleaning efficiency and more convenience.

[0008] In an alternative embodiment, the cleaning component can be driven to rotate by the airflow in the cyclone separation chamber 101. By utilizing the airflow in the cyclone separation chamber to drive the cleaning component to rotate, real-time cleaning effect can be achieved when the cleaning component rotates, without adding an additional power source, simplifying the structure and saving costs. Moreover, it can also realize the synchronous and real-time cleaning of the dust on the filter component and the cyclone separation chamber during the operation of the dust-gas separation device, with better cleaning effect, greatly improving the dust cleaning efficiency, avoiding the problem of dust accumulation on the filter screen component and the cyclone separation chamber, and thus being able to further improve the filtering effect of the filter screen component and the cleanliness inside the cyclone separation chamber. In addition, by utilizing the airflow during the operation of the dust-gas separation device to drive the cleaning component to rotate for dust cleaning, there is no need for manual operation for dust cleaning, which is more convenient and provides a better user experience.

[0010] Beneficial effects: By providing a third dust cleaning part on the side of the scraping plate close to the bottom wall of the cyclone separation chamber, the third dust cleaning part is in contact with the bottom wall of the cyclone separation chamber. Thus, when the cleaning component is driven to rotate by the airflow, the third dust cleaning part can clean the dust on the entire bottom wall of the cyclone separation chamber, thereby achieving a more comprehensive and thorough dust cleaning treatment for the inner wall of the cyclone separation chamber, and further ensuring the cleanliness and hygiene inside the cyclone separation chamber.

[0011] In an alternative embodiment, the cleaning bracket further includes: A mounting plate, the scraping plate is fixed to the bottom wall of the mounting plate, there are two scraping plates, and the two scraping plates are symmetrically distributed.

[0012] Beneficial effects: By providing two scraping plates, the dust cleaning effect and efficiency can be further improved. And with the symmetric design of the two scraping plates, the balance and stability of the entire cleaning component during rotation can be further enhanced.

[0013] In an alternative embodiment, mounting grooves are provided on the outer wall of the scraping plate, and the dust cleaning parts are mounted and fixed in the mounting grooves. Beneficial effects: By providing the mounting grooves on the outer wall of the scraping plate, the dust cleaning parts are embedded and installed in the mounting grooves, which is more convenient for the installation and fixation of the dust cleaning parts.

[0014] In an alternative embodiment, the dust cleaning part includes any one or a combination of a brush strip, a soft rubber strip, and a sponge strip.

[0015] Beneficial effects: By using a brush strip, a soft rubber strip, and a sponge strip for the dust cleaning part, both the dust scraping effect can be ensured, and the filter screen and the dust cup will not be scratched or damaged.

[0016] In an alternative embodiment, an air inlet is provided at the bottom of the cyclone separation chamber, and an air outlet is provided at the top; A spiral rising structure is provided at the bottom of the cyclone separation chamber. After the air flow enters the cyclone separation chamber from the air inlet, it spirally rises under the action of the spiral rising structure and can drive the cleaning component to rotate.

[0017] Beneficial effects: By providing the spiral rising structure at the air inlet of the cyclone separation chamber, when the air enters the cyclone separation chamber from the air inlet, it will spiral upward. The dust in the air flow enters the dust collection chamber under the action of centrifugal force, and the clean air enters the vacuum motor through the filter screen, realizing dust-air separation. The spirally rising air flow can also drive the cleaning component to rotate, thereby realizing real-time cleaning of the dust on the filter screen and the inner wall of the cyclone separation chamber. The dust cleaning effect is better, and there is no need to additionally install a power source or manual operation, which is more convenient.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Cleaning devices such as mite removers and vacuum cleaners are emerging household cleaning products at present, mainly used to clean dust and mites in household products and disinfect them to provide a more suitable living environment for humans. The dust cups of existing cleaning devices such as mite removers and vacuum cleaners adopt a double-cup design. The cyclone separation chamber on one side is used to separate dust and air, and the dust collection chamber on the other side is used to collect dust. Although there will be no large accumulation of dust in the cyclone separation chamber, during the process of using the centrifugal force generated by the airflow rotating in the cyclone separation chamber to concentrate the dust into the dust collection chamber, the dust will collide with the cup wall and filter screen of the cyclone separation chamber and adhere to them, which requires users to clean it frequently to avoid affecting the filtering effect. Moreover, both chambers need to be cleaned, increasing the maintenance workload and resulting in a poor experience.

[0030] The dust cup cleaning solutions disclosed in the related art only clean the dust collection cavity and the filter screen. By setting a filter screen dust scraping component, when the filter screen is disassembled, the filter screen dust scraping component moves relative to the filter screen to scrape the dust on the filter screen and reduce filter screen blockage. Although this solution can clean the dust on the filter screen, it cannot clean the dust on the wall of the cyclone separation cavity cup. Moreover, the filter screen assembly needs to be removed to clean the filter screen, which not only requires manual operation but also is rather troublesome to take the cup lid back and forth, being very inconvenient. At the same time, when using the method of pulling out the filter screen to clean the dust, the scraped dust is also likely to spread to the external environment, resulting in a poor user experience. And the filter screen dust scraping component needs to be arranged around the entire outer circumference of the filter screen, occupying a large space and being inconvenient for installation and layout.

[0031] The following combines Figures 1 to 12 , to describe the embodiments of the present invention.

[0032] According to an embodiment of the present invention, on the one hand, the present invention provides a dust-gas separation device, including: a dust cup 10, a filter assembly 20, and a cleaning assembly 30. The dust cup 10 has a cyclone separation cavity 101; the filter assembly 20 is arranged in the cyclone separation cavity 101 and is used for filtering the air flow; the cleaning assembly 30 is rotatably arranged between the filter assembly 20 and the inner wall of the cyclone separation cavity 101, and the cleaning assembly 30 is in contact and cooperation with the outer wall of the filter assembly 20 and the inner wall of the cyclone separation cavity 101; the cleaning assembly 30 is used for cleaning the dust on the filter assembly 20 and the inner wall of the cyclone separation cavity 101 when being driven to rotate.

[0033] In the above embodiment, by using the rotation of the cleaning assembly, 360-degree all-round and dead-angle-free cleaning of the filter assembly and the cyclone separation cavity can be realized, with better cleaning effect, higher efficiency, and the cleaning assembly does not need to be arranged around the entire circumference, occupying less space and being convenient for installation and layout. When the dust-gas separation device works, external air enters the cyclone separation cavity 101, and the air flow rotates in the cyclone separation cavity 101 to drive the cleaning assembly 30 to rotate. Since the cleaning assembly 30 is in contact and cooperation with the outer wall of the filter assembly 20 and the inner wall of the cyclone separation cavity 101, the rotating cleaning assembly 30 can clean the dust on the outer wall of the filter assembly 20 and the inner wall of the cyclone separation cavity 101, avoiding the problems of internal pollution and bacteria breeding in the dust cup 10 caused by long-term dust accumulation on the filter assembly 20 and the inner wall of the cyclone separation cavity 101. Further, in the present application, the rotating cleaning assembly can simultaneously clean the dust on the inner walls of the filter assembly and the cyclone separation cavity, further improving the dust cleaning efficiency and effect, keeping the cup wall of the cyclone separation cavity 101 and the filter assembly 20 clean and hygienic. Moreover, since the cyclone separation cavity 101 and the filter assembly are cleaned simultaneously by using the same cleaning assembly 30, it can also reduce the user's maintenance workload, simplify the structure, save resources, and provide a better user experience.

[0034] Preferably, the cleaning component can rotate under the driving action of the airflow in the cyclone separation chamber 101, and during the rotation process, it can clean the dust on both the filter component 20 and the cyclone separation chamber 101 simultaneously. By using the airflow in the cyclone separation chamber 101 to drive the cleaning component 30 to rotate, the cleaning component can achieve real-time cleaning effect during rotation, without adding an additional power source, simplifying the structure and saving costs. Moreover, it can also clean the dust on the filter component 20 and the cyclone separation chamber 101 synchronously and in real time during the working process of the dust-gas separation device, with a better dust cleaning effect, greatly improving the dust cleaning efficiency, avoiding the problem of dust accumulation on the filter component and the cyclone separation chamber 101, and thus being able to further improve the filtering effect of the filter component and the cleanliness inside the cyclone separation chamber 101. In addition, by using the airflow during the working process of the dust-gas separation device to drive the cleaning component 30 to rotate for dust cleaning, manual operation is not required, which is more convenient and provides a better user experience.

[0035] Specifically, in this embodiment, the cleaning component 30 is rotatably arranged in the cyclone separation chamber 101. The cleaning component 30 is in contact and cooperation with the outer wall of the filter component, and the cleaning component 30 is also in contact and cooperation with the inner wall of the cyclone separation chamber 101. The dust cup 10 also has a dust collection chamber 102, and the dust collection chamber 102 is interconnected with the cyclone separation chamber 101. The centrifugal force generated by the rotation of the airflow in the cyclone separation chamber 101 can concentrate the dust into the dust collection chamber 102.

[0036] Furthermore, the dust-gas separation device further includes a separator arranged in the cyclone separation chamber 101. A filter component is arranged on the separator to filter the dust in the airflow and prevent the dust from directly entering the vacuum motor. The dust cup 10 includes a cup body 11 and a cup cover 12. The cup body 11 has a double-cup structure, which is divided into two cavities, namely the dust collection chamber 102 and the cyclone separation chamber 101. An air outlet 1012 is arranged between the dust collection chamber 102 and the cyclone separation chamber 101 to connect the two cavities, so that the dust in the cyclone separation chamber 101 can enter the dust collection chamber 102. In this embodiment, a spiral rising structure 111 is arranged at the air inlet 1011 of the cyclone separation chamber 101. When the air enters the cyclone separation chamber 101 from this air inlet 1011, it will spiral upward in the cyclone separation chamber 101. The dust in the airflow enters the dust collection chamber 102 under the action of centrifugal force, and the clean air enters the vacuum motor through the filter component, realizing dust-gas separation.

[0037] In some embodiments, in combination with Figure 1 、 Figures 3 to 5As shown, a cyclone air duct is formed between the outer periphery of the filtering component 20 and the inner periphery of the cyclone separation chamber 101. The cleaning component 30 includes a cleaning bracket 31 and a dust cleaning member 32. The cleaning bracket 31 includes a scraping plate 311 adapted to extend into the cyclone air duct. The scraping plate 311 has a first side close to the inner peripheral wall of the cyclone separation chamber 101 and a second side close to the outer peripheral wall of the filtering component 20. The dust cleaning member 32 includes a first dust cleaning portion 321 provided on the first side of the scraping plate 311 and a second dust cleaning portion 322 provided on the second side of the scraping plate 311. The first dust cleaning portion 321 is adapted to contact the inner peripheral wall of the cyclone separation chamber 101, and the second dust cleaning portion 322 is adapted to contact the outer peripheral wall of the filtering component 20.

[0038] In the above embodiment, the dust cleaning member 32 includes a first dust cleaning portion 321 provided on the side of the scraping plate 311 close to the inner peripheral wall of the cyclone separation chamber 101 and a second dust cleaning portion 322 provided on the side of the scraping plate 311 close to the outer peripheral wall of the filtering component 20. The first dust cleaning portion 321 contacts the inner peripheral wall of the cyclone separation chamber 101, and the second dust cleaning portion 322 contacts the outer peripheral wall of the filtering component 20. Thus, when the cleaning component 30 is driven to rotate by the airflow, the first dust cleaning portion 321 can clean the dust on the entire inner peripheral wall of the cyclone separation chamber 101, and the second dust cleaning portion 322 can clean the dust on the entire outer peripheral wall of the filtering component 20, realizing the simultaneous cleaning of the dust in the cyclone separation chamber 101 and the filtering component 20, with higher dust cleaning efficiency and greater convenience.

[0039] Specifically, the scraping plate 311 is of a strip-shaped structure. The width of the strip-shaped scraping plate 311 is slightly smaller than the gap distance between the outer periphery of the filtering component 20 and the inner periphery of the cyclone separation chamber 101. The strip-shaped scraping plate 311 is inserted into the gap space between the filtering component 20 and the cyclone separation chamber 101. Let the width of the strip-shaped scraping plate 311 be D1, the gap between the outer peripheral wall of the filtering component 20 and the inner peripheral wall of the cyclone separation chamber 101 be D2, and the width of the scraping plate 311 after assembling the dust cleaning member 32 be D3. Among them, D2 > D1 and D3 ≤ D2. The first dust cleaning portion 321 is correspondingly provided on the outer peripheral side of the filtering component 20, and the length of the first dust cleaning portion 321 is greater than or equal to the axial length of the filtering component 20. The second dust cleaning portion 322 is correspondingly provided on the inner peripheral side of the cyclone separation chamber 101, and the length of the second dust cleaning portion 322 is less than or equal to the axial length of the cyclone separation chamber 101 of the filtering component.

[0040] Preferably, the first dust cleaning portion 321 abuts against the inner peripheral wall of the cyclone separation chamber 101, and the second dust cleaning portion 322 abuts against the outer peripheral wall of the filtering component 20.

[0041] In some embodiments, the scraping plate 311 further has a third side close to the bottom wall of the cyclone separation chamber 101. The dust cleaning member 32 further includes a third dust cleaning portion 323 provided on the third side of the scraping plate 311. The third dust cleaning portion 323 is adapted to contact the bottom wall of the cyclone separation chamber 101.

[0042] In the above embodiments, through the third dust cleaning part 323 provided on the side of the scraping plate 311 close to the bottom wall of the cyclone separation chamber 101, the third dust cleaning part 323 is in contact with the bottom wall of the cyclone separation chamber 101. Thus, when the cleaning assembly 30 is driven to rotate by the airflow, the third dust cleaning part 323 can clean the dust on the entire bottom wall of the cyclone separation chamber 101, thereby realizing a more comprehensive and thorough dust cleaning treatment for the inner wall of the cyclone separation chamber 101, and further ensuring the cleanliness and hygiene inside the cyclone separation chamber 101.

[0043] Preferably, the third dust cleaning part 323 is in abutment with the bottom wall of the cyclone separation chamber 101. The length of the third dust cleaning part 323 is equal to the radius of the cyclone separation chamber 101 minus the radius of the filter assembly 20.

[0044] In some embodiments, the cleaning bracket 31 further includes a mounting plate 312, and the scraping plate 311 is fixed to the bottom wall of the mounting plate 312. There are two scraping plates 311, and the two scraping plates 311 are symmetrically distributed.

[0045] In the above embodiments, by providing two scraping plates 311, the dust cleaning effect and efficiency can be further improved. And with the symmetric design of the two scraping plates 311, the balance stability of the entire cleaning assembly 30 during rotation can be further improved.

[0046] Specifically, as shown in Figure 1 、 Figure 3 and Figure 12 , the cyclone separation chamber 101 is in a cylindrical shape, the filter assembly 20 is in a cylindrical shape, the filter assembly 20 is coaxially arranged with the cyclone separation chamber 101, the cleaning assembly 30 extends along the axial direction of the cyclone separation chamber 101, the extension length of the cleaning assembly 30 is not less than the length of the filter assembly 20, the airflow spirally rises in the cyclone separation chamber 101, and the airflow can drive the cleaning assembly 30 to rotate during the rising process.

[0047] Further, the filter assembly 20 includes a filter cartridge bracket 21 and a filter mesh 22 arranged on the outer periphery of the cylindrical bracket. The filter mesh 22 is in a cylindrical shape, and the cylindrical filter mesh 22 is coaxially arranged with the cyclone separation chamber 101. The cyclone air duct is an annular hollow cavity. The length direction of the scraping plate 311 is consistent with the axial direction of the filter mesh 22, and the plate surface of the scraping plate 311 is parallel to the radial direction of the cyclone air duct, that is, the width direction of the scraping plate 311 is consistent with the radial direction of the cyclone air duct. Of course, the plate surface of the scraping plate 311 can also intersect with the radial direction of the cyclone air duct, as long as it is ensured that there is a certain component of the plate surface of the scraping plate 311 in the radial direction of the cyclone air duct and the airflow can blow onto the plate surface of the scraping plate 311 to drive it to rotate.

[0048] Furthermore, in this embodiment, the scraper 311 is not limited to a flat plate structure. The scraper 311 can also adopt a bent vane or curved vane structure, similar to a fan blade, to increase the contact area with the air flow and facilitate the rotation driven by the air flow.

[0049] Furthermore, a first dust cleaning part 321 is arranged on the outer side end face of the scraper 311, a second dust cleaning part 322 is arranged on the inner side end face of the scraper 311, and a third dust cleaning part 323 is arranged on the lower end face of the scraper 311. The distance between the second dust cleaning parts 322 on the two inner sides of the two scrapers 311 is less than or equal to the outer diameter of the filter screen 22, and the distance between the first dust cleaning parts 321 on the two outer sides of the two scrapers 311 is greater than or equal to the diameter of the cyclone separation chamber 101. Such a design ensures that the dust cleaning parts 32 located inside and outside the scraper 311 can contact or abut against the filter screen 22 and the inner wall of the cyclone separation chamber 101.

[0050] In some embodiments, an installation groove 3110 is arranged on the outer wall of the scraper 311, and the dust cleaning part 32 is installed and fixed in the installation groove 3110. In the above embodiment, through the installation groove 3110 arranged on the outer wall of the scraper 311, the dust cleaning part 32 is embedded and installed in the installation groove 3110, which is more convenient for the installation and fixation of the dust cleaning part 32.

[0051] Specifically, installation grooves 3110 are arranged on the first side, second side, and third side of the scraper 311, and the installation grooves 3110 on the three sides are communicated with each other, which is convenient for the installation of the dust cleaning part 32. The first dust cleaning part 321 is embedded and installed in the installation groove 3110 on the first side of the scraper 311, the second dust cleaning part 322 is embedded and installed in the installation groove 3110 on the second side of the scraper 311, and the second dust cleaning part 322 is embedded and installed in the installation groove 3110 on the third side of the scraper 311. The entire installation groove 3110 is arranged in a U shape on the inner side end face, outer side end face, and bottom side end face of the scraper 311. Through the dust cleaning parts 32 arranged on the three sides of the scraper 311, the inner peripheral wall of the cyclone separation chamber 101, the outer peripheral wall of the filter screen 22, and the bottom wall of the cyclone separation chamber 101 can be cleaned simultaneously.

[0052] In some embodiments, the dust cleaning part 32 includes any one or a combination of a brush strip, a soft rubber strip, and a sponge strip.

[0053] In the above embodiment, by adopting a brush strip, a soft rubber strip, and a sponge strip for the dust cleaning part 32, the dust scraping effect can be ensured, and the filter screen 22 and the dust cup 10 will not be scratched or damaged.

[0054] Preferably, in this embodiment, the dust cleaning part 32 adopts a brush strip, which has a good dust scraping effect and a small frictional resistance with the filter screen 22 and the dust cup 10. More preferably, the brush strip is a soft brush.

[0055] In this embodiment, the dust cleaning member 32 can be fixed in the installation groove 3110 with glue, or the dust cleaning member 32 can also be press-fitted into the installation groove 3110 to achieve fixation. This embodiment does not limit the specific fixation method of the dust cleaning member 32.

[0056] In some embodiments, an air inlet 1011 is provided at the bottom of the cyclone separation chamber 101, and an air outlet 1012 is provided at the top; a spiral rising structure 111 is provided at the bottom of the cyclone separation chamber 101. After the air flow enters the cyclone separation chamber 101 from the air inlet 1011, it spirally rises under the action of the spiral rising structure 111 and can drive the cleaning assembly 30 to rotate.

[0057] In the above embodiment, through the spiral rising structure 111 provided at the air inlet 1011 of the cyclone separation chamber 101, when the air enters the cyclone separation chamber 101 from the air inlet 1011, it will spiral upward. The dust in the air flow enters the dust collection chamber 102 under the action of centrifugal force, and the clean air enters the vacuum motor through the filter screen 22, realizing dust-air separation. The spirally rising air flow can also drive the cleaning assembly 30 to rotate, thereby realizing real-time cleaning of the dust on the filter screen 22 and the inner wall of the cyclone separation chamber 101. The dust cleaning effect is better, and there is no need to additionally install a power source, nor manual operation, which is more convenient.

[0058] Specifically, the spiral rising structure 111 includes spiral blades provided at the bottom of the cyclone separation chamber 101. The air inlet end of the spiral blades is communicated with the air inlet 1011, and the air outlet end is communicated with the air inlet end of the cyclone air duct.

A cyclone separation chamber 101 is formed in the cup body 11, and the cup cover 12 is provided at the opening of the cup body 11 in an openable and closable manner; the dust-air separation device further includes a rotating assembly 40, and the cleaning assembly 30 is rotatably connected to the cup cover 12 through the rotating assembly 40. In the above embodiment, the cleaning assembly 30 is rotatably and freely connected to the cup cover 12 through the rotating assembly 40, so that the cleaning assembly 30 and the cup cover 12 are assembled into one body. When it is desired to maintain and replace the cleaning assembly 30, directly open the cup cover 12, and the cleaning assembly 30 can be taken out together with the cup cover 12, which is very convenient and fast. After the maintenance and replacement are completed, directly snap the cup cover 12 onto the cup body, and the installation of the cleaning assembly 30 can be achieved, eliminating the step of separately assembling the cleaning assembly 30 into the cyclone separation chamber 101, improving the assembly efficiency, providing great convenience for users, and having a better user experience.

[0060] Specifically, an opening is provided at the top of the cup body 11, and the cup cover 12 is provided at the top opening of the cup body 11 in an openable and closable manner. Preferably, the cup cover 12 is snap-fitted and installed at the opening of the cup body 11.

The bearing 42 is press-fitted into the bearing mounting portion 410. A bearing mounting post 121 is provided on the cup lid 12. The bearing 42 is rotatably sleeved on the bearing mounting post 121 and axially limited by the screw 43. In the above embodiment, a bearing mounting post 121 is provided on the bottom wall of the cup lid 12. During assembly, first press-fit the bearing 42 onto the bearing mounting portion 410 of the turntable 41, then sleeved the bearing 42 on the bearing mounting post 121 of the cup lid 12, and fix it with the screw 43 to limit the axial displacement of the bearing 42 and the turntable 41. The turntable 41 can rotate freely. The cleaning assembly 30 is mounted on the turntable 41 and rotates together with the turntable 41.

[0062] Specifically, as shown in Figure 1 , Figure 2 , Figures 5 to 8 , the cup lid 12 includes a detachable upper lid and a lower lid. The upper lid and the lower lid enclose a cavity. A bearing mounting post 121 is fixedly provided on the bottom wall of the lower lid. The bearing mounting post 121 is located at the center of the cyclone separation chamber 101. The turntable 41 includes a turntable body 411. The turntable body 411 is circular. A shaft hole is provided at the center of the turntable body 411. The turntable 41 is sleeved on the bearing mounting post 121 through the shaft hole. The turntable 41 and the bearing 42 can rotate freely relative to the bearing mounting post 121. The bearing mounting portion 410 includes a surrounding wall 4102 provided on the outer periphery of the shaft hole. The surrounding wall 4102 is located on the side wall of the turntable body 411 away from the upper lid, and a set distance is reserved between the surrounding wall 4102 and the edge of the shaft hole. An annular upper limiting wall 4101 is formed between the inner periphery of the surrounding wall 4102 and the shaft hole. An installation space for accommodating the limiting bearing 42 is enclosed between the surrounding wall 4102 and the annular upper limiting wall 4101. The bearing 42 is in interference fit with the surrounding wall 4102 to realize the fixation of the bearing 42 and the turntable 41. As shown in Figures 6 to 9 , the inner diameter of the annular upper limiting wall 4101 is smaller than the outer diameter of the bearing 42. The abutting fit between the annular upper limiting wall 4101 and the upper end surface of the bearing 42 can prevent the turntable 41 from moving downward, further improving the stability of the axial position of the turntable 41.

[0063] Furthermore, a bearing limiting step 1210 is provided on the cup lid 12 to limit the installation position of the bearing 42. Preferably, the bearing mounting post 121 is provided in a stepped shape. The stepped surface of the stepped bearing mounting post 121 constitutes the bearing limiting step 1210. The bearing limiting step 1210 abuts against the upper end surface of the bearing 42 to limit the upward displacement of the bearing 42.

[0064] Furthermore, as shown inFigures 5 to 7 , Figure 11 As shown in Figure 11 , a relief portion 3122 is provided at the center of the mounting plate 312 corresponding to the bearing mounting portion 410 of the turntable 41. The relief portion 3122 is recessed from the center of the mounting plate 312 in a direction away from the turntable 41, and a relief groove for accommodating the bearing mounting portion 410 is formed in the relief portion 3122. The outer diameter of the nut of the screw 43 is larger than the inner diameter of the bearing 42, and the axial position of the bearing 42 can be limited.

[0065] In the first embodiment, in combination with Figure 6 , Figure 7 and Figure 11 , a relief hole is provided in the bottom wall of the relief portion 3122. The inner diameter of the relief hole is larger than the outer diameter of the nut of the screw 43. The screw 43 only restricts the axial displacement of the bearing 42 and the turntable 41, without restricting the cleaning bracket 31. The cleaning bracket 31 and the turntable 41 are detachably clamped and fixed, which is convenient for detaching and assembling the cleaning assembly 30 separately. Preferably, the inner diameter of the relief hole is smaller than the outer diameter of the bearing 42. The bottom wall of the relief portion 3122 constitutes an annular lower limit wall 31220. The lower limit wall 31220 abuts against the lower end surface of the bearing 42 and the lower end surface of the bearing mounting portion 410 at the center of the turntable 41, restricting the downward displacement of the bearing 42, further improving the stability of the axial position of the bearing 42, and when the cleaning bracket 31 and the turntable 41 are installed together, the lower limit wall 31220 can restrict the upward movement of the cleaning bracket 31 and the turntable 41.

[0066] In the second embodiment, a connection hole is provided in the bottom wall of the relief portion 3122. The inner diameter of the connection hole is smaller than the outer diameter of the nut of the screw 43. The screw 43 passes through the connection hole and is connected to the bearing mounting post 121. A rotational clearance is reserved between the nut of the screw 43 and the bottom wall of the bearing mounting portion 410. The screw 43 can restrict the axial displacement of the bearing 42, the turntable 41 and the cleaning bracket 31, and the bearing 42, the turntable 41 and the cleaning bracket 31 can rotate freely in the circumferential direction.

[0067] In this embodiment, the cleaning assembly 30 is detachably assembled in the dust cup 10, which is convenient for replacement when the cleaning assembly 30 is worn, and the user experience is better.

[0068] Preferably, the cleaning assembly 30 is detachably rotatably connected to the cup cover 12.

[0069] Specifically, the dust-gas separation device includes a turntable 41. The turntable 41 is rotatably connected to the cup cover 12, and the cleaning assembly 30 is detachably connected to the turntable 41.

[0070] ​​​​​​In the above embodiments, when it is desired to maintain and replace the cleaning component 30, the cup lid 12 is directly opened, and the cleaning component 30 can be taken out together with the cup lid 12. The user can directly disassemble the cleaning component 30 from the turntable 41 for replacement, which is very convenient and fast. After the maintenance and replacement are completed, after assembling the cleaning component 30 onto the turntable 41, the cup lid 12 is directly snapped onto the cup body, and the installation of the cleaning component 30 can be achieved, eliminating the step of separately assembling the cleaning component 30 into the cyclone separation chamber 101, improving the assembly efficiency, providing great convenience for the user, and having a better user experience.

[0071] In some embodiments, the cleaning component 30 is snap-connected to the turntable 41.

[0072] In the above embodiments, the cleaning component 30 is fixed to the turntable 41 by snap connection. Not only is the fixation firm and stable, but the cleaning component 30 can be disassembled and assembled without the aid of external tools, which is more convenient and fast.

[0073] Of course, in other alternative embodiments, the cleaning component 30 and the turntable 41 can be detachably fixed by means of screws 43 or interference plug-in fit, etc.

[0074] In some embodiments, the cleaning component 30 includes a cleaning bracket 31. An elastic buckle 3121 is provided on the cleaning bracket 31, and a card slot 4120 is provided on the turntable 41. The elastic buckle 3121 is snap-fitted into or disengaged from the card slot 4120 through deformation.

[0075] In the above embodiments, through the elastic buckle 3121 provided on the cleaning bracket 31 and the corresponding card slot 4120 provided on the turntable 41, the quick disassembly and assembly of the cleaning component 30 can be realized by using the elastic deformation of the elastic buckle 3121. Specifically, in use, the cleaning component 30 is fixed to the turntable 41 by snap-fitting the elastic buckle 3121 with the card slot 4120 on the turntable 41, and the cleaning component 30 is removed by pressing the elastic buckle 3121 to make it deform and disengage from the card slot 4120. The disassembly and assembly are more convenient and fast.

[0076] In some embodiments, there are two groups of elastic buckles 3121, and the two groups of elastic buckles 3121 are symmetrically arranged on the cleaning bracket 31; two groups of card slots 4120 are correspondingly provided on the turntable 41. In the above embodiments, by providing two groups of elastic buckles 3121 on the cleaning bracket 31, the fixing effect of the cleaning component 30 can be improved, and by adopting a symmetrical design for the two groups of elastic buckles 3121, the balance stability of the entire cleaning component 30 during rotation can be further improved. In addition, the two symmetrically arranged groups of elastic buckles 3121 also facilitate the user to pinch and remove the cleaning component 30 from the turntable 41 with fingers.

[0077] Specifically, the cleaning bracket 31 includes a mounting plate 312 and a scraping plate 311. Elastic buckles 3121 are arranged on the mounting plate 312, and the scraping plate 311 is fixed on the mounting plate 312. A dust cleaning member 32 is arranged on the outer wall of the scraping plate 311, and the dust cleaning member 32 is in contact and cooperation with the outer wall of the filter assembly 20 and the inner wall of the cyclone separation chamber 101 respectively. The elastic buckles 3121 are fixedly arranged on the mounting plate 312. The mounting plate 312 is circular, and two groups of elastic buckles 3121 are symmetrically arranged on the mounting plate 312.

[0078] Preferably, in this embodiment, the midline connection of the two scraping plates 311 is perpendicular to the midline connection of the two elastic buckles 3121, that is, the two scraping plates 311 and the two elastic buckles 3121 are evenly spaced along the circumferential direction of the mounting plate 312, and the scraping plates 311 and the elastic buckles 3121 are arranged alternately. Such an arrangement can effectively ensure the balance and stability of the entire cleaning assembly 30.

[0079] In some embodiments, as Figures 5 to 10 shown, the cleaning bracket 31 is provided with a plug-in limit groove 3120, and the turntable 41 is provided with a plug-in limit rib 412; the plug-in limit rib 412 is inserted and positioned in the plug-in limit groove 3120, and a clamping groove 4120 is opened on the plug-in limit rib 412.

[0080] In the above embodiment, through the cooperation of the plug-in limit rib 412 and the plug-in limit groove 3120, the limit cooperation between the turntable 41 and the cleaning bracket 31 in the circumferential direction can be realized, ensuring that the turntable 41 and the cleaning bracket 31 can rotate together. And by opening the clamping groove 4120 on the plug-in limit rib 412, it is convenient for the clamping groove 4120 to cooperate with the elastic buckle 3121, so that the plug-in limit rib 412 can not only realize the limit of the turntable 41 and the cleaning bracket 31 in the circumferential direction, but also play a role in facilitating the connection between the turntable 41 and the cleaning bracket 31, serving multiple purposes with one object and simplifying the structure.

[0081] Specifically, the plug-in limit groove 3120 is opened at the position of the elastic buckle 3121. The position on the mounting plate 312 where the elastic buckle 3121 is provided is correspondingly provided with a plug-in limit groove 3120, and the plug-in limit rib 412 is fixedly arranged on the bottom wall of the turntable 41.

[0082] Preferably, two insertion limiting ribs 412 are provided on the turntable 41 to improve the stability of circumferential limiting. More preferably, the two insertion limiting ribs 412 are symmetrically designed to ensure the balanced force of the turntable 41 and the balance stability of the turntable 41 during rotation. Corresponding to the two insertion limiting ribs 412, two insertion limiting grooves 3120 are provided on the mounting plate 312 of the cleaning bracket 31. The two insertion limiting ribs 412 are correspondingly inserted into the two insertion limiting grooves 3120, so that the cleaning bracket 31 can rotate with the turntable 41. Grooves 4120 are provided on both of the two insertion limiting ribs 412 to cooperate with the elastic buckles 3121 of the cleaning bracket 31, so as to further improve the fixing effect on the cleaning bracket 31.

[0083] In some embodiments, in combination with Figures 5 to 7 、 Figure 10 、 Figure 11 As shown, the elastic buckle 3121 includes an elastic rib 31211 and a clamping boss 31212. The elastic rib 31211 is formed on the cleaning bracket 31 and can elastically deform relative to the cleaning bracket 31 when subjected to an external force; the clamping boss 31212 is provided on the elastic rib 31211, and the clamping boss 31212 can be clamped into the groove 4120 or disengaged from the groove 4120 when the elastic rib 31211 elastically deforms.

[0084] In the above embodiment, the elastic rib 31211 has a set extension length and can be more easily deformed when subjected to an external force. By providing the clamping boss 31212 on the elastic rib 31211, it is more convenient for the elastic buckle 3121 to be clamped into the groove 4120 or disengaged from the groove 4120 when the elastic rib 31211 elastically deforms.

[0085] Specifically, in combination with Figure 7 、 Figure 10 、 Figure 11 As shown, the elastic rib 31211 includes an arc section and a straight section. The arc section is connected between the straight section and the mounting plate 312. Through the design of the arc section of the elastic rib 31211, it is easier to deform. Preferably, an insertion limiting groove 3120 is formed on the mounting plate 312. One end of the elastic rib 31211 is connected to the inner wall of one side of the insertion limiting groove 3120, and the other end bends and extends away from the turntable 41. By connecting the elastic rib 31211 to the inner wall of the insertion limiting groove 3120, the insertion limiting groove 3120 can provide sufficient avoidance space for the deformation of the elastic buckle 3121, making the elastic buckle 3121 easier to deform. At the same time, it can also improve the tightness of the cooperation between the groove 4120 on the insertion limiting rib 412 and the elastic buckle 3121.

[0086] Furthermore, as shown in Figure 5 、 Figures 7 to 11As shown, the elastic rib 31211 is strip-shaped, and the cross-section of the plug-in limiting rib 412 is U-shaped or C-shaped. An accommodating space that can accommodate the elastic rib 31211 and limit it is formed by enclosing inside the U-shaped or C-shaped plug-in limiting rib 412. The elastic buckle 3121 is limited within the accommodating space inside the plug-in limiting rib 412, thereby being able to reduce the risk of the clamping boss 31212 accidentally detaching from the card slot 4120.

[0087] Specifically, the plug-in limiting rib 412 includes two opposite first side walls and a second side wall connected to one side of the two first side walls. The distance between the two first side walls matches the width of the elastic rib 31211, and the distance between the two first side walls is greater than or equal to the width of the elastic rib 31211. A card slot 4120 is provided on the second side wall.

[0088] In some embodiments, one side wall of the clamping boss 31212 close to the turntable 41 is provided with an inclined guiding surface 312120. In the above embodiment, through the inclined guiding surface 312120 provided on the clamping boss 31212, the elastic buckle 3121 is more easily deformed by extrusion during installation. The inclined guiding surface 312120 plays a guiding role, making the clamping boss 31212 of the elastic buckle 3121 more easily engaged with the card slot 4120 to avoid mechanical jamming.

[0089] Specifically, the clamping boss 31212 is provided on the outer side wall of the elastic rib 31211. One side wall of the clamping boss 31212 close to the mounting plate 312 is configured as an inclined guiding surface 312120, and one side wall of the clamping boss 31212 far from the mounting plate 312 is configured as a flat clamping surface perpendicular to the elastic rib 31211.

[0090] In some embodiments, the clamping boss 31212 divides the elastic rib 31211 into a connecting section and a pinching section. The connecting section is arranged between the cleaning bracket 31 and the pinching section, and anti-slip lines 312110 are provided on the pinching section.

[0091] In the above embodiment, the provided pinching section facilitates the user to pinch and press the elastic buckle 3121 for unlocking operation. When the user wants to disassemble and replace the cleaning component 30, the user can place two fingers on the pinching sections of the two elastic ribs 31211 and apply inward force to make the elastic buckle 3121 disengage from the card slot 4120, realizing unlocking of the cleaning bracket 31 and replacing the cleaning component 30. Through the anti-slip lines 312110 provided on the pinching section, the friction between the hand and the pinching section can be increased to avoid slipping during disassembly and assembly.

[0092] Specifically, the pinching section is located at one end of the elastic rib 31211 away from the mounting plate 312. The pinching section has a set extension length to facilitate pinching by the user. The outer wall surface of the pinching section is the unlocking operation surface, and anti-slip patterns are provided on the unlocking operation surface. Anti-slip patterns 312110 are provided on the two outer side walls of the pinching sections of the two elastic buckles 3121 that face each other.

[0093] Next, the specific structures, assembly methods, working processes, and effects of the dust cup 10, the filter assembly 20, and the cleaning assembly 30 in this embodiment will be introduced in detail with reference to the accompanying drawings.

[0094] As Figures 4 to 6 shown, the cup cover assembly includes a cup cover 12, a rotating assembly 40, and a cleaning assembly 30. Among them, the rotating assembly 40 includes a bearing 42, a turntable 41, and a screw 43. The cleaning assembly 30 includes a cleaning bracket 31 and an ash cleaning member 32. The ash cleaning member 32 is preferably made of soft bristles. During assembly, first press-fit the bearing 42 onto the turntable 41, and then install the bearing 42 on the cup cover 12 and fix it with the screw 43. The turntable 41 can rotate freely. The cleaning bracket 31 is detachably installed on the turntable 41 and rotates together with the turntable 41. A bearing installation post 121 is provided on the cup cover 12, and the bearing 42 is installed on the bearing installation post 121. A bearing limit step 1210 is provided on the cup cover 12 to limit the installation position of the bearing 42.

[0095] As Figure 8 and Figure 9 shown, a bearing installation portion 410 is provided on the turntable 41, and the bearing 42 is installed inside the bearing installation portion 410. Two insertion limit ribs 412 are also provided on the turntable 41. The optimal solution is a symmetric design, which cooperates with the insertion limit slots 3120 on the cleaning bracket 31 to drive the cleaning bracket 31 to rotate. A card slot 4120 is provided on the insertion limit rib 412 to cooperate with the elastic buckle 3121 of the cleaning bracket 31 to fix the cleaning bracket 31. An upper limit wall 4101 is provided on the bearing installation portion 410 of the turntable 41, which can cooperate with the bearing 42 to prevent the turntable 41 from moving downward.

[0096] As Figure 10 and Figure 11As shown in the figure, two scraping plates 311 are provided on the cleaning bracket 31. The optimal solution is a symmetric design. An installation groove 3110 is provided on the scraping plate 311, and soft bristles are installed in the installation groove 3110 and fixed with glue. Two insertion limit grooves 3120 are provided on the cleaning bracket 31, which cooperate with the insertion limit ribs 412 on the turntable 41, so that the cleaning bracket 31 can rotate together with the turntable 41. An elastic buckle 3121 is provided on the cleaning bracket 31, which cooperates with the card slot 4120 on the turntable 41 to fix the cleaning bracket 31 on the turntable 41. The elastic buckle 3121 can be detached from the card slot 4120 by deformation to achieve disassembly. An inclined guiding surface 312120 is provided on the elastic buckle 3121 to make the elastic buckle 3121 easier to deform during installation. A pinching section is provided on the elastic buckle 3121. The pinching section has an unlocking operation surface, and an anti-slip pattern 312110 is provided on the unlocking operation surface. When the user places two fingers on the anti-slip pattern 312110 and presses inward, the elastic buckle 3121 can be detached from the card slot 4120, unlocking the cleaning bracket 31 for replacement. A lower limit wall 31220 is provided on the cleaning bracket 31. After the cleaning bracket 31 and the turntable 41 are installed together, the lower limit wall 31220 restricts the upward movement of the cleaning bracket 31 and the turntable 41.

[0097] As Figure 7 shown, when installing the cleaning bracket 31, align the insertion limit groove 3120 of the cleaning bracket 31 with the insertion limit rib 412 of the turntable 41 and press it inward. When the elastic buckle 3121 touches the insertion limit rib 412, it automatically deforms inward. After continuing to press it in place, the clamping boss 31212 of the elastic buckle 3121 is snapped into the card slot 4120, and the cleaning bracket 31 is installed in place and fixed on the turntable 41 to rotate with the turntable 41. When disassembling the cleaning bracket 31, place two fingers on the pinching section of the elastic buckle 3121 of the cleaning bracket 31 and press inward to deform the elastic buckle 3121, so that the clamping boss 31212 is detached from the card slot 4120, unlocking the cleaning bracket 31, and then take out the cleaning bracket 31 outward.

[0098] After the cup lid assembly is assembled, when the entire cup lid assembly is placed into the cup body 11, when the dust and gas separation device works, air enters from the air inlet 1011 of the cyclone separation chamber 101 and rotates in the cyclone separation chamber 101 to drive the cleaning bracket 31 to rotate. The inner soft bristles clean the dust on the filter screen 22 during rotation, and the outer soft bristles clean the dust on the cup wall of the cyclone separation chamber 101 during rotation. Using the airflow to rotate the cleaning bracket 31 to clean the dust on the cup wall and the filter screen 22 of the cyclone separation chamber 101 in real time during the use of the dust and gas separation device can keep the cup wall and the filter screen 22 of the cyclone separation chamber 101 clean, reduce the workload of the user to clean the dust cup 10, and since the cleaning bracket 31 is set as a detachable structure, it is convenient to replace after the bristles are worn, providing a better user experience.

[0099] According to an embodiment of the present invention, on the other hand, a cleaning device is provided, including the dust-gas separation device of any of the above embodiments.

[0100] In some embodiments, the cleaning device includes at least one of a mite remover, a vacuum cleaner, a floor sweeping robot, and a window cleaning robot.

[0101] Preferably, in this embodiment, the cleaning device is a mite remover, and the dust-gas separation device is applied to the mite remover.

[0102] The present invention solves the problem of dust cleaning of the cup wall of the cyclone separation chamber 101 and the filter screen 22 of the dust-gas separation device in the prior art. By providing a rotatable turntable 41 on the cup cover 12 of the dust cup 10, a detachable cleaning bracket 31 is installed on the turntable 41. Soft bristles are installed on the inner and outer sides of the cleaning bracket 31. The outer soft bristles can contact the cup wall of the cyclone separation chamber 101, and the inner soft bristles can contact the filter screen 22. When the mite remover works, air enters the cyclone separation chamber 101 from the inlet of the dust-gas separation device. The air rotates in the cyclone separation chamber 101 to drive the cleaning bracket 31 to rotate. The inner soft bristles clean the dust on the filter screen 22 during rotation, and the outer soft bristles clean the dust on the cup wall during rotation. The cleaning bracket 31 is rotated by the airflow without adding an additional power source. During the use of the mite remover, the dust on the cup wall of the cyclone separation chamber 101 and the filter screen 22 is cleaned in real time, which can keep the cup wall of the cyclone separation chamber 101 and the filter screen 22 clean, reduce the workload of the user for cleaning the dust cup 10, and the cleaning bracket 31 is set as a detachable structure, which is convenient to replace after the bristles are worn, and the user experience is better.

[0103] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the protection scope of the embodiments of the present application.
