Description

Technical Field

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

[0002] Cleaning equipment such as mite removers and vacuum cleaners are currently emerging household cleaning products. They usually use a vacuum pump to generate adsorption force to absorb dust and other dirt from the surface to be cleaned, and then use a dust-gas separation device to separate the airflow carrying dust and other dirt to filter and collect the dust. Finally, the filtered relatively clean airflow is released into the environment to achieve a cleaning effect.

[0003] The dust cup of the dust and gas separation device in the related technology is provided with a cyclone separation chamber, which uses the centrifugal force generated by the rotation of the airflow to separate and collect dust. In this process, the dust will collide with the inner wall and filter of the cyclone separation chamber and adhere to it, which is inconvenient to clean. After long-term use, it will cause internal contamination of the cyclone separation chamber, affecting subsequent user use, and even breeding bacteria. In addition, the dust adhering to the filter screen can easily 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 and gas separation device and a cleaning device to solve the problem in the prior art that dust easily adheres to the inner wall and filter screen of the cyclone separation chamber of the dust and gas separation device and is inconvenient to clean.

[0005] In a first aspect, the present invention provides a dust-gas separation device, comprising:

[0006] A dust cup having a cyclone separation chamber;

[0007] A filter assembly is provided in the cyclone separation chamber and is used to filter the airflow;

[0008] A cleaning assembly is rotatably disposed between the filter assembly and the cyclone separation chamber, the cleaning assembly being in contact with both the outer wall of the filter assembly and the inner wall of the cyclone separation chamber, and being used to clean dust on the filter assembly and the cyclone separation chamber when driven to rotate;

[0009] The outer periphery of the filter assembly and the inner periphery of the cyclone separation chamber form a cyclone air duct. The cleaning assembly includes:

[0010] a cleaning support including a scraper adapted to extend into the cyclone duct;

[0011] The dust cleaning member, the scraper having 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;

[0012] The cleaning member includes a first cleaning portion arranged on the first side of the scraper and a second cleaning portion arranged on the second side of the scraper. The first cleaning portion is suitable for contacting the inner peripheral wall of the cyclone separation chamber, and the second cleaning portion is suitable for contacting the outer peripheral wall of the filter assembly.

[0013] Beneficial effects: By utilizing the rotation of the cleaning component, the filter component and the cyclone separation chamber can be cleaned 360 degrees in all directions without dead angles, with better cleaning effect and higher efficiency. The cleaning component does not need to be arranged around the entire circumference, takes up less space, and is easy to install and arrange. When the dust and gas separation device is working, 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 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 problem of long-term dust accumulation in the filter component and the cyclone separation chamber causing internal contamination of the dust cup and breeding of bacteria. Furthermore, 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 cleaning efficiency and cleaning effect, keeping the cup wall and filter component of the cyclone separation chamber clean and hygienic, and the cyclone separation chamber and the filter assembly are cleaned at the same time by using the same cleaning component, which can also reduce the user's maintenance workload, simplify the structure, save resources, and provide a better user experience.

[0014] Furthermore, the cleaning component includes a first cleaning portion arranged on the scraper side close to the inner peripheral wall of the cyclone separation chamber and a second cleaning portion close to the outer peripheral wall of the filter assembly. The first cleaning portion contacts the inner peripheral wall of the cyclone separation chamber, and the second cleaning portion contacts the outer peripheral wall of the filter assembly. Therefore, when the cleaning assembly is driven to rotate by the airflow, the first cleaning portion can clean the dust on the entire inner peripheral wall of the cyclone separation chamber, and the second cleaning portion can clean the dust on the entire outer peripheral wall of the filter assembly, thereby achieving simultaneous cleaning of the dust in the cyclone separation chamber and the filter assembly, with higher cleaning efficiency and greater convenience.

[0015] In an optional embodiment, the cleaning component can rotate under the driving action of the airflow in the cyclone separation chamber 101. By utilizing the airflow in the cyclone separation chamber to drive the cleaning component to rotate, a real-time cleaning effect is achieved when the cleaning component rotates, without the need to add an additional power source, simplifying the structure and saving costs. It is also possible to achieve synchronous and real-time cleaning of dust on the filter component and the cyclone separation chamber during the operation of the dust and gas separation device, which has a better cleaning effect, greatly improves the cleaning efficiency, and avoids the problem of dust accumulation on the filter component and the cyclone separation chamber, thereby further improving the filtering effect of the filter component and the cleanliness of the inside of the cyclone separation chamber. In addition, by utilizing the airflow during the operation of the dust and gas separation device to drive the cleaning component to rotate for cleaning, no manual operation is required for cleaning, which is more convenient and provides a better user experience.

[0016] In an optional embodiment, the scraper further has a third side close to the bottom wall of the cyclone separation chamber;

[0017] The ash cleaning member further comprises a third ash cleaning portion arranged on a third side of the scraper, and the third ash cleaning portion is suitable for contacting the bottom wall of the cyclone separation chamber.

[0018] Beneficial effect: By arranging the third cleaning part on the side of the scraper close to the bottom wall of the cyclone separation chamber, the third cleaning part contacts the bottom wall of the cyclone separation chamber, so that when the cleaning component is driven to rotate by the airflow, the third cleaning part can clean the dust on the entire bottom wall of the cyclone separation chamber, thereby achieving a more comprehensive and thorough cleaning treatment of the inner wall of the cyclone separation chamber, and further ensuring the cleanliness and hygiene of the inside of the cyclone separation chamber.

[0019] In an optional embodiment, the cleaning support further comprises:

[0020] The mounting plate and the scraper are fixed on the bottom wall of the mounting plate. There are two scrapers, and the two scrapers are symmetrically distributed.

[0021] Beneficial effect: By providing two scrapers, the cleaning effect and efficiency can be further improved, and the two scrapers can further improve the balance stability of the entire cleaning component during the rotation process by adopting a symmetrical design.

[0022] In an optional embodiment, a mounting groove is provided on the outer wall of the scraper, and the dust cleaning member is mounted and fixed in the mounting groove.

[0023] Beneficial effect: The dust cleaning component is embedded and installed in the installation groove provided on the outer wall of the scraper, which makes it more convenient to install and fix the dust cleaning component.

[0024] In an optional embodiment, the cleaning member includes any one or a combination of a brush strip, a soft rubber strip, and a sponge strip.

[0025] Beneficial effect: The dust cleaning parts adopt brush strips, soft rubber strips and sponge strips, which can ensure the dust scraping effect without damaging or scratching the filter and dust cup.

[0026] In an optional embodiment, the cyclone separation chamber is provided with an air inlet at the bottom and an air outlet at the top;

[0027] A spiral rising structure is provided at the bottom of the cyclone separation chamber. After the airflow 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.

[0028] Beneficial effect: By setting a spiral rising structure at the air inlet of the cyclone separation chamber, the air will spirally rise when entering the cyclone separation chamber from the air inlet. The dust in the air flow enters the dust collecting chamber under the action of centrifugal force, and the clean air enters the vacuum motor through the filter to achieve dust and gas separation. The spiral rising airflow can also drive the cleaning component to rotate, thereby achieving real-time cleaning of the dust on the filter and the inner wall of the cyclone separation chamber, with better cleaning effect, and no additional power source is required, and no manual operation is required, which is more convenient.

[0029] In an optional embodiment, the dust cup includes:

[0030] A cup body and a cup cover, wherein a cyclone separation chamber is formed in the cup body and the cup cover is openably and closably arranged at the opening of the cup body;

[0031] The dust and gas separation device also includes a rotating assembly, and the cleaning assembly is rotatably connected to the cup cover through the rotating assembly.

[0032] Beneficial effects: The cleaning component can be freely rotatably connected to the cup cover through the rotating component, so that the cleaning component and the cup cover are assembled into one. When you want to maintain and replace the cleaning component, you can directly open the cup cover and take out the cleaning component together with the cup cover, which is very convenient and quick. After the maintenance and replacement is completed, you can directly snap the cup cover onto the cup body to install the cleaning component, eliminating the step of separately assembling the cleaning component to the cyclone separation chamber, improving assembly efficiency, providing great convenience for users, and better user experience.

[0033] In an optional embodiment, the rotating assembly includes:

[0034] The cleaning assembly is mounted on a turntable, and a bearing mounting portion is provided at the center of the turntable;

[0035] The bearing assembly includes a bearing and a screw, and the bearing is interference-mounted on the bearing mounting portion;

[0036] A bearing mounting column is provided on the cup cover, and the bearing is rotatably sleeved on the bearing mounting column and axially limited by screws.

[0037] Beneficial effect: A bearing mounting column is provided on the bottom wall of the cup cover. During assembly, the bearing is first interference-mounted on the bearing mounting portion of the turntable, and then the bearing sleeve is installed on the bearing mounting column of the cup cover and fixed with screws to limit the axial displacement of the bearing and the turntable. The turntable can rotate freely, and the cleaning component is installed on the turntable and rotates with the turntable.

[0038] In a second aspect, the present invention further provides a cleaning device comprising the dust and gas separation device of any one of the above embodiments.

[0064] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0065] In the description of the present invention, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0066] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0067] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0068] Mite removers, vacuum cleaners and other cleaning equipment are currently emerging household cleaning products. They are mainly used to clean dust and mites from household products and disinfect them to provide a more suitable living environment for humans. The dust cups of existing mite removers, vacuum cleaners and other cleaning equipment adopt a double-cup design. The cyclone separation chamber on one side is used to separate dust and gas, and the dust collection chamber on the other side is used to collect dust. Although there will not be a large amount of dust accumulation in the cyclone separation chamber, the dust will collide with the cup wall and filter of the cyclone separation chamber and adhere to it during the process of using the centrifugal force generated by the airflow rotating in the cyclone separation chamber to collect the dust in the dust collection chamber. Users need to clean it frequently to avoid affecting the filtering effect. In addition, the need to clean both chambers increases the maintenance workload and the user experience is not good.

[0069] The dust cup cleaning solution disclosed in the related art only cleans the dust collection chamber and filter. By providing a filter scraper component, the filter scraper component and the filter are moved relative to each other when the filter is removed to scrape the dust off the filter and reduce filter blockage. Although this solution can clean the dust on the filter, it cannot clean the dust on the cyclone separation chamber cup wall. In addition, the filter assembly needs to be removed to clean the filter, which not only requires manual operation, but also is very troublesome to take the cup cover back and forth, which is very inconvenient. At the same time, the dust is easily spread to the external environment by pulling out the filter, which leads to a poor user experience. In addition, the filter scraper component needs to be arranged around the entire periphery of the filter, which takes up a lot of space and is inconvenient to install and arrange.

[0070] The following combination Figures 1 to 12 , describing embodiments of the present invention.

[0071] According to an embodiment of the present invention, on the one hand, the present invention provides a dust and 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 chamber 101; the filter assembly 20 is arranged in the cyclone separation chamber 101, for filtering the airflow; the cleaning assembly 30 is rotatably arranged between the filter assembly 20 and the cyclone separation chamber 101, and the cleaning assembly 30 is in contact with the outer wall of the filter assembly 20 and the inner wall of the cyclone separation chamber 101; the cleaning assembly 30 is used to clean dust on the filter assembly 20 and the cyclone separation chamber 101 when driven to rotate.

[0072] In the above embodiment, by utilizing the rotation of the cleaning component, it is possible to achieve 360-degree all-round cleaning of the filter component and the cyclone separation chamber without dead angles, resulting in better cleaning effect and higher efficiency. In addition, the cleaning component does not need to be arranged around the entire circumference, which occupies less space and is convenient for installation and arrangement. When the dust and gas separation device is working, external air enters the cyclone separation chamber 101, and the airflow rotates in the cyclone separation chamber 101, driving the cleaning component 30 to rotate. Since the cleaning component 30 is in contact with the outer wall of the filter component 20 and the inner wall of the cyclone separation chamber 101, the rotating cleaning component 30 can clean the dust on the filter component 20 and the inner wall of the cyclone separation chamber 101, avoiding the problem of long-term dust accumulation in the filter component 20 and the cyclone separation chamber 101 causing internal contamination of the dust cup 10 and the breeding of bacteria. Furthermore, the rotating cleaning component in the present application can simultaneously clean the dust on the filter component and the inner wall of the cyclone separation chamber, further improving the cleaning efficiency and cleaning effect, keeping the cup wall and filter component 20 of the cyclone separation chamber 101 clean and hygienic, and the cyclone separation chamber 101 and the filter component are cleaned at the same time by using the same cleaning component 30, which can also reduce the user's maintenance workload, simplify the structure, save resources, and provide a better user experience.

[0073] Preferably, the cleaning assembly is capable of rotating under the influence of the airflow within the cyclone separation chamber 101, and during this rotation, it is capable of simultaneously cleaning dust from the filter assembly 20 and the cyclone separation chamber 101. By utilizing the airflow within the cyclone separation chamber 101 to drive the cleaning assembly 30 to rotate, a real-time cleaning effect is achieved during the rotation of the cleaning assembly, eliminating the need for an additional power source, simplifying the structure, and saving costs. Furthermore, it is possible to simultaneously and in real time clean dust from the filter assembly 20 and the cyclone separation chamber 101 during operation of the dust and gas separation device, resulting in a better cleaning effect, greatly improving cleaning efficiency, and avoiding the problem of dust accumulation on the filter assembly and the cyclone separation chamber 101, thereby further improving the filtering effect of the filter assembly and the cleanliness of the interior of the cyclone separation chamber 101. Furthermore, by utilizing the airflow during the operation of the dust and gas separation device to drive the cleaning assembly 30 to rotate and clean dust, no manual operation is required, which is more convenient and provides a better user experience.

[0074] Specifically, in this embodiment, the cleaning component 30 is rotatably arranged in the cyclone separation chamber 101, the cleaning component 30 contacts and cooperates with the outer wall of the filter component, and the cleaning component 30 also contacts and cooperates with the inner wall of the cyclone separation chamber 101. The dust cup 10 also has a dust collecting chamber 102, and the dust collecting chamber 102 is connected to the cyclone separation chamber 101. The centrifugal force generated by the rotation of the airflow in the cyclone separation chamber 101 can collect dust in the dust collecting chamber 102.

[0075] Furthermore, the dust and gas separation device also includes a separator arranged in the cyclone separation chamber 101, and a filter assembly is provided on the separator for filtering dust in the airflow to 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 is a double-cup structure, divided into two cavities: a dust collecting chamber 102 and a cyclone separation chamber 101. An air outlet 1012 is provided between the dust collecting 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 collecting chamber 102. In this embodiment, a spiral rising structure 111 is 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 spirally rises in the cyclone separation chamber 101. The dust in the airflow enters the dust collecting chamber 102 under the action of centrifugal force, and the clean air enters the vacuum motor through the filter assembly, thereby realizing dust and gas separation.

[0076] In some embodiments, combined Figure 1 、 Figures 3 to 5 As shown, the periphery of the filter assembly 20 and the inner periphery of the cyclone separation chamber 101 form a cyclone air duct, and the cleaning assembly 30 includes a cleaning bracket 31 and a cleaning member 32. The cleaning bracket 31 includes a scraper 311 suitable for extending into the cyclone air duct, and the scraper 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 filter assembly 20; the cleaning member 32 includes a first cleaning portion 321 arranged on the first side of the scraper 311 and a second cleaning portion 322 arranged on the second side of the scraper 311, the first cleaning portion 321 is suitable for contacting the inner peripheral wall of the cyclone separation chamber 101, and the second cleaning portion 322 is suitable for contacting the outer peripheral wall of the filter assembly 20.

[0077] In the above embodiment, the cleaning part 32 includes a first cleaning part 321 arranged on the inner peripheral wall side of the scraper 311 close to the cyclone separation chamber 101 and a second cleaning part 322 close to the outer peripheral wall side of the filter assembly 20. The first cleaning part 321 contacts the inner peripheral wall of the cyclone separation chamber 101, and the second cleaning part 322 contacts the outer peripheral wall of the filter assembly 20. Therefore, when the cleaning assembly 30 is driven to rotate by the airflow, the first cleaning part 321 can clean the dust on the entire inner peripheral wall of the cyclone separation chamber 101, and the second cleaning part 322 can clean the dust on the entire outer peripheral wall of the filter assembly 20, thereby achieving simultaneous cleaning of the dust in the cyclone separation chamber 101 and the filter assembly 20, with higher cleaning efficiency and greater convenience.

[0078] Specifically, the scraper 311 is a strip-shaped structure. The width of the strip-shaped scraper 311 is slightly smaller than the gap between the outer periphery of the filter assembly 20 and the inner periphery of the cyclone separation chamber 101. The strip-shaped scraper 311 is inserted into the gap between the filter assembly 20 and the cyclone separation chamber 101. The width of the strip-shaped scraper 311 is set to D1, the gap between the outer peripheral wall of the filter assembly 20 and the inner peripheral wall of the cyclone separation chamber 101 is set to D2, and the width of the scraper 311 after the cleaning member 32 is assembled is D3, where D2>D1 and D3≤D2. The first cleaning portion 321 is correspondingly arranged on the outer periphery of the filter assembly 20. The length of the first cleaning portion 321 is greater than or equal to the axial length of the filter assembly 20. The second cleaning portion 322 is correspondingly arranged on the inner periphery of the cyclone separation chamber 101. The length of the second cleaning portion 322 is less than or equal to the axial length of the filter assembly cyclone separation chamber 101.

[0079] Preferably, the first ash cleaning portion 321 abuts against the inner peripheral wall of the cyclone separation chamber 101 , and the second ash cleaning portion 322 abuts against the outer peripheral wall of the filter assembly 20 .

[0080] In some embodiments, the scraper 311 also has a third side close to the bottom wall of the cyclone separation chamber 101; the cleaning member 32 also includes a third cleaning portion 323 arranged on the third side of the scraper 311, and the third cleaning portion 323 is suitable for contacting the bottom wall of the cyclone separation chamber 101.

[0081] In the above embodiment, by setting the third cleaning part 323 on the bottom wall side of the scraper 311 close to the cyclone separation chamber 101, the third cleaning part 323 is in contact with the bottom wall of the cyclone separation chamber 101, so that when the cleaning component 30 is driven to rotate by the airflow, the third cleaning part 323 can clean the dust on the entire bottom wall of the cyclone separation chamber 101, thereby achieving a more comprehensive and thorough cleaning treatment of the inner wall of the cyclone separation chamber 101, further ensuring the cleanliness and hygiene of the inside of the cyclone separation chamber 101.

[0082] Preferably, the third ash cleaning portion 323 abuts against the bottom wall of the cyclone separation chamber 101. The length of the third ash cleaning portion 323 is equal to the radius of the cyclone separation chamber 101 minus the radius of the filter assembly 20.

[0083] In some embodiments, the cleaning bracket 31 further includes a mounting plate 312 , and a scraper 311 is fixed to the bottom wall of the mounting plate 312 . There are two scrapers 311 , and the two scrapers 311 are symmetrically distributed.

[0084] In the above embodiment, by providing two scrapers 311, the cleaning effect and efficiency can be further improved, and the two scrapers 311 can further improve the balance stability of the entire cleaning assembly 30 during the rotation process by adopting a symmetrical design.

[0085] Specifically, combined Figure 1 、 Figure 3 and Figure 12 As shown, the cyclone separation chamber 101 is cylindrical, the filter assembly 20 is cylindrical, 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, and 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.

[0086] Furthermore, the filter assembly 20 includes a filter cartridge holder 21 and a filter screen 22 disposed on the periphery of the cylindrical holder. The filter screen 22 is cylindrical and is coaxially disposed with the cyclone separation chamber 101. The cyclone duct is an annular hollow cavity. The length direction of the scraper 311 is consistent with the axial direction of the filter screen 22. The surface of the scraper 311 is parallel to the radial direction of the cyclone duct, that is, the width direction of the scraper 311 is consistent with the radial direction of the cyclone duct. Of course, the surface of the scraper 311 can also intersect with the radial direction of the cyclone duct, as long as the surface of the scraper 311 has a certain weight in the radial direction of the cyclone duct and the airflow can blow onto the surface of the scraper 311 to drive it to rotate.

[0087] Furthermore, in this embodiment, the scraper 311 is not limited to a straight plate structure. The scraper 311 can also adopt a bent blade or a curved blade structure, similar to a fan blade, to increase the contact area with the airflow and facilitate airflow-driven rotation.

[0088] Furthermore, a first cleaning portion 321 is provided on the outer end face of the scraper 311, a second cleaning portion 322 is provided on the inner end face of the scraper 311, and a third cleaning portion 323 is provided on the lower end face of the scraper 311. The distance between the second cleaning portions 322 on the inner sides of the two scrapers 311 is less than or equal to the outer diameter of the filter 22, and the distance between the first cleaning portions 321 on the outer sides of the two scrapers 311 is greater than or equal to the diameter of the cyclone separation chamber 101. This design ensures that the cleaning parts 32 located on the inner and outer sides of the scraper 311 can contact or abut the filter 22 and the inner wall of the cyclone separation chamber 101.

[0089] In some embodiments, a mounting groove 3110 is provided on the outer wall of the scraper 311 , and the dust cleaning member 32 is installed and fixed in the mounting groove 3110 .

[0090] In the above embodiment, the dust cleaning member 32 is embedded and installed in the mounting groove 3110 provided on the outer wall of the scraper 311 , which makes it more convenient to install and fix the dust cleaning member 32 .

[0091] Specifically, mounting grooves 3110 are provided on the first, second, and third sides of the scraper 311. These mounting grooves 3110 on the three sides are interconnected, facilitating the installation of the cleaning element 32. The first cleaning portion 321 is embedded in the mounting groove 3110 on the first side of the scraper 311. The second cleaning portion 322 is embedded in the mounting groove 3110 on the second side of the scraper 311. The third cleaning portion 322 is embedded in the mounting groove 3110 on the third side of the scraper 311. The mounting grooves 3110 are arranged in a U-shape on the inner, outer, and bottom end surfaces of the scraper 311. The cleaning elements 32 provided on the three sides of the scraper 311 can simultaneously clean the inner circumferential wall of the cyclone separation chamber 101, the outer circumferential wall of the filter screen 22, and the bottom wall of the cyclone separation chamber 101.

[0100] In the above embodiment, the cleaning component 30 is freely rotatably connected to the cup cover 12 through the rotating component 40, so that the cleaning component 30 and the cup cover 12 are assembled into one. When you want to maintain and replace the cleaning component 30, just open the cup cover 12, and the cleaning component 30 can be taken out together with the cup cover 12, which is very convenient and quick. After the maintenance and replacement is completed, the cup cover 12 is directly snapped onto the cup body to achieve the installation of the cleaning component 30, eliminating the step of separately assembling the cleaning component 30 to the cyclone separation chamber 101, thereby improving assembly efficiency, providing great convenience for users, and providing a better user experience.

The surrounding wall 4102 is located on the side wall of the turntable body 411 away from the upper cover, and a set distance is reserved between the surrounding wall 4102 and the edge of the shaft hole. An annular upper limit wall 4101 is formed between the inner periphery of the surrounding wall 4102 and the shaft hole. The surrounding wall 4102 and the annular upper limit wall 4101 enclose an installation space for accommodating the limit bearing 42. The bearing 42 and the surrounding wall 4102 have an interference fit to achieve the fixation of the bearing 42 and the turntable 41. Figures 6 to 9 As shown, the inner diameter of the annular upper limit wall 4101 is smaller than the outer diameter of the bearing 42. The abutment between the annular upper limit 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.

[0105] Furthermore, a bearing limiting step 1210 is provided on the cup cover 12 for limiting the installation position of the bearing 42. Preferably, the bearing mounting column 121 is arranged in a stepped shape, and the step surface of the stepped bearing mounting column 121 constitutes a bearing limiting step 1210. The bearing limiting step 1210 is abutted against the upper end surface of the bearing 42 to limit the upward displacement of the bearing 42.

[0106] Further, combined with Figures 5 to 7 、 Figure 11 As shown, 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 formed by recessing the center of the mounting plate 312 away from the turntable 41. A relief groove is formed within the relief portion 3122 to accommodate the bearing mounting portion 410. The outer diameter of the nut of the screw 43 is larger than the inner diameter of the bearing 42, thereby limiting the axial position of the bearing 42.

[0107] In a first embodiment, the combination Figure 6 、 Figure 7 and Figure 11 As shown, a relief hole is provided on 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 limits the axial displacement of the bearing 42 and the turntable 41, but does not limit the cleaning bracket 31. The cleaning bracket 31 and the turntable 41 are separately fixed and clamped together, which facilitates the separate disassembly and assembly of the cleaning assembly 30. 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 forms 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, limiting 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 limit the upward movement of the cleaning bracket 31 and the turntable 41.

The screw 43 can limit 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.

[0109] In this embodiment, the cleaning component 30 is detachably assembled in the dust cup 10, which is convenient for replacement when the cleaning component 30 is worn, and provides a better user experience.

[0110] Preferably, the cleaning assembly 30 is detachably and rotatably connected to the cup cover 12 .

[0111] Specifically, the dust and gas separation device includes a turntable 41 , which is rotatably connected to the cup cover 12 , and the cleaning component 30 is detachably connected to the turntable 41 .

[0112] In the above embodiment, when you want to maintain and replace the cleaning component 30, you can directly open the cup cover 12, and the cleaning component 30 can be taken out together with the cup cover 12. The user can directly remove the cleaning component 30 from the turntable 41 for replacement, which is very convenient and quick. After the maintenance and replacement is completed, after assembling the cleaning component 30 onto the turntable 41, directly snap the cup cover 12 onto the cup body to achieve the installation of the cleaning component 30, eliminating the step of separately assembling the cleaning component 30 to the cyclone separation chamber 101, thereby improving assembly efficiency, providing great convenience for users, and providing a better user experience.

[0113] In some embodiments, the cleaning assembly 30 is engaged with the turntable 41 .

[0114] In the above embodiment, the cleaning assembly 30 and the turntable 41 are fixed by snapping together, which is not only firm and stable, but also allows the cleaning assembly 30 to be disassembled and assembled without the aid of external tools, which is more convenient and quick.

[0115] Of course, in other alternative embodiments, the cleaning assembly 30 and the turntable 41 can be detachably fixed by means of screws 43 or interference fit.

[0116] In some embodiments, the cleaning assembly 30 includes a cleaning bracket 31 , the cleaning bracket 31 is provided with an elastic buckle 3121 , and the turntable 41 is provided with a slot 4120 . The elastic buckle 3121 is engaged in or disengaged from the slot 4120 through deformation.

[0117] In the above embodiment, by providing an elastic clip 3121 on the cleaning bracket 31 and a corresponding slot 4120 on the turntable 41, the elastic deformation of the elastic clip 3121 can be utilized to achieve quick disassembly and assembly of the cleaning component 30. Specifically, during use, the cleaning component 30 is fixed on the turntable 41 by engaging the elastic clip 3121 with the slot 4120 on the turntable 41. The cleaning component 30 can be removed by pressing the elastic clip 3121 to deform it and disengage it from the slot 4120, making disassembly and assembly more convenient and quick.

[0118] 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 ; and two groups of card slots 4120 are correspondingly arranged on the turntable 41 .

[0119] In the above embodiment, the two sets of elastic clips 3121 provided on the cleaning bracket 31 can improve the fixing effect of the cleaning assembly 30. The symmetrical design of the two sets of elastic clips 3121 can further improve the balance and stability of the entire cleaning assembly 30 during rotation. In addition, the symmetrical arrangement of the two sets of elastic clips 3121 also makes it easier for the user to remove the cleaning assembly 30 from the turntable 41 by pinching with their fingers.

[0120] Specifically, the cleaning bracket 31 includes a mounting plate 312 and a scraper 311. Elastic clips 3121 are mounted on the mounting plate 312, and the scraper 311 is fixed to the mounting plate 312. A dust cleaning member 32 is mounted on the outer wall of the scraper 311. The dust cleaning member 32 contacts and engages with the outer wall of the filter assembly 20 and the inner wall of the cyclone separation chamber 101, respectively. The elastic clips 3121 are fixedly mounted on the mounting plate 312, which is circular in shape. Two sets of elastic clips 3121 are symmetrically arranged on the mounting plate 312.

[0121] Preferably, in this embodiment, the center line connecting the two scrapers 311 is perpendicular to the center line connecting the two elastic clips 3121, that is, the two scrapers 311 and the two elastic clips 3121 are evenly spaced along the circumference of the mounting plate 312, and the scrapers 311 and the elastic clips 3121 are alternately arranged. Such an arrangement can effectively ensure the balance and stability of the entire cleaning assembly 30.

[0122] In some embodiments, as Figures 5 to 10 As shown, the cleaning bracket 31 is provided with an insertion limit groove 3120, and the turntable 41 is provided with an insertion limit rib 412; the insertion limit rib 412 is inserted and positioned in the insertion limit groove 3120, and the card slot 4120 is opened on the insertion limit rib 412.

[0123] In the above embodiment, by cooperating with the plug-in limiting rib 412 and the plug-in limiting groove 3120, the turntable 41 and the cleaning bracket 31 can be limited in the circumferential direction, ensuring that the turntable 41 and the cleaning bracket 31 can rotate together, and by opening the card slot 4120 on the plug-in limiting rib 412, the card slot 4120 is conveniently matched with the elastic clip 3121, so that the plug-in limiting rib 412 can not only realize the limitation of the turntable 41 and the cleaning bracket 31 in the circumferential direction, but also facilitate the connection between the turntable 41 and the cleaning bracket 31, so that one thing has multiple uses and a simplified structure.

[0124] Specifically, the plug-in limiting groove 3120 is provided at the elastic buckle 3121 , and the plug-in limiting groove 3120 is provided corresponding to the position where the elastic buckle 3121 is provided on the mounting plate 312 . The plug-in limiting rib 412 is fixedly provided on the bottom wall of the turntable 41 .

[0125] Preferably, two plug-in limiting ribs 412 are provided on the turntable 41 to improve the stability of the circumferential limit. More preferably, the two plug-in limiting ribs 412 are symmetrically designed to ensure that the turntable 41 is subjected to balanced force and ensure the balance and stability of the turntable 41 during rotation. Two plug-in limiting grooves 3120 are correspondingly provided on the mounting plate 312 of the cleaning bracket 31. The two plug-in limiting ribs 412 are correspondingly plugged into the two plug-in limiting grooves 3120, so that the cleaning bracket 31 can rotate with the turntable 41. Both plug-in limiting ribs 412 are provided with a slot 4120 that cooperates with the elastic buckle 3121 of the cleaning bracket 31 to further improve the fixing effect of the cleaning bracket 31.

[0126] In some embodiments, combined Figures 5 to 7 、 Figure 10 、 Figure 11 As shown, the elastic buckle 3121 includes an elastic rib 31211 and a snap-fitting boss 31212. The elastic rib 31211 is formed on the cleaning bracket 31, and the elastic rib 31211 can be elastically deformed relative to the cleaning bracket 31 when subjected to external force; the snap-fitting boss 31212 is arranged on the elastic rib 31211, and the snap-fitting boss 31212 can be engaged in the slot 4120 or disengaged from the slot 4120 when the elastic rib 31211 is elastically deformed.

[0127] In the above embodiment, the elastic rib 31211 has a set extension length, which can make it easier to deform when subjected to external force. By setting the locking boss 31212 on the elastic rib 31211, it is more convenient for the elastic buckle 3121 to be engaged with or disengaged from the slot 4120 when the elastic rib 31211 undergoes elastic deformation.

[0128] Specifically, combined Figure 7 、 Figure 10 、 Figure 11 As shown, the elastic rib 31211 includes an arcuate section and a straight section, with the arcuate section connected between the straight section and the mounting plate 312. The arcuate section design makes the elastic rib 31211 easier to deform. Preferably, a plug-in limit slot 3120 is defined on the mounting plate 312. One end of the elastic rib 31211 is connected to an inner wall of the plug-in limit slot 3120, and the other end is bent and extended away from the turntable 41. By connecting the elastic rib 31211 to the inner wall of the plug-in limit slot 3120, the plug-in limit slot 3120 provides sufficient clearance for the elastic buckle 3121 to deform, making the elastic buckle 3121 easier to deform and improving the compactness of the fit between the slot 4120 on the plug-in limit rib 412 and the elastic buckle 3121.

[0129] Furthermore, if 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 limiting 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 limiting space inside the plug-in limiting rib 412, thereby reducing the risk that the clamping boss 31212 accidentally disengages from the card slot 4120.

[0130] 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, the distance between the two first side walls is greater than or equal to the width of the elastic rib 31211, and a card slot 4120 is provided on the second side wall.

[0131] In some embodiments, one side wall of the clamping boss 31212 close to the turntable 41 is provided with an inclined guiding surface 312120.

[0132] In the above embodiments, 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 into the card slot 4120 to avoid mechanical jamming.

[0133] 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, and the clamping surface is perpendicular to the elastic rib 31211.

[0134] In some embodiments, the clamping boss 31212 divides the elastic rib 31211 into a connecting section and a pinching section. The connecting section is provided between the cleaning bracket 31 and the pinching section, and anti-slip lines 312110 are provided on the pinching section.

[0135] In the above embodiments, 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 force inward to make the elastic buckle 3121 disengage from the card slot 4120, realizing unlocking 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, avoiding the phenomenon of slipping during disassembly and assembly.

[0136] 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 user pinching. The outer wall surface of the pinching section is the unlocking operation surface, and the unlocking operation surface is provided with anti-slip grooves. Anti-slip grooves 312110 are provided on the two opposite outer side walls of the pinching section of the two elastic buckles 3121.

[0137] The specific structure, assembly method, working process and effect of the dust cup 10, filter assembly 20 and cleaning assembly 30 of this embodiment are described in detail below with reference to the accompanying drawings.

[0138] like Figures 4 to 6 As shown, the cup cover assembly includes a cup cover 12, a rotating assembly 40, and a cleaning assembly 30, wherein 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 a cleaning part 32, and the cleaning part 32 preferably uses soft bristles. During assembly, the bearing 42 is first interference-mounted on the turntable 41, and then the bearing 42 is mounted on the cup cover 12 and fixed with screws 43, so that the turntable 41 can rotate freely. The cleaning bracket 31 can be detachably mounted on the turntable 41 and rotates with the turntable 41. A bearing mounting column 121 is provided on the cup cover 12, and the bearing 42 is mounted on the bearing mounting column 121. A bearing limit step 1210 is provided on the cup cover 12 to limit the installation position of the bearing 42.

[0139] like Figure 8 and Figure 9 As shown, the turntable 41 is provided with a bearing mounting portion 410, within which the bearing 42 is mounted. The turntable 41 is also provided with two insertion limit ribs 412, preferably symmetrically designed, which cooperate with the insertion limit slots 3120 on the cleaning bracket 31 to drive the cleaning bracket 31 to rotate. The insertion limit ribs 412 are provided with a latching slot 4120, which cooperates with the elastic latch 3121 of the cleaning bracket 31 to secure the cleaning bracket 31. The bearing mounting portion 410 of the turntable 41 is provided with an upper limit wall 4101, which cooperates with the bearing 42 to prevent the turntable 41 from moving downward.

[0140] like Figure 10 and Figure 11As shown, the cleaning bracket 31 is provided with two scrapers 311. The optimal solution is a symmetrical design. The scrapers 311 are provided with mounting grooves 3110, and the soft bristles are installed in the mounting grooves 3110 and fixed with glue. The cleaning bracket 31 is provided with two plug-in limit grooves 3120, which cooperate with the plug-in limit ribs 412 on the turntable 41 to enable the cleaning bracket 31 to rotate together with the turntable 41. The cleaning bracket 31 is provided with an elastic clip 3121, which cooperates with the clip groove 4120 on the turntable 41 to fix the cleaning bracket 31 to the turntable 41. The elastic clip 3121 can be disassembled by deforming out of the clip groove 4120. The elastic clip 3121 is provided with an inclined guide surface 312120 to make the elastic clip 3121 easier to deform during installation. The elastic buckle 3121 is provided with a gripping section having an unlocking operation surface. The unlocking operation surface is provided with anti-slip grooves 312110. The user places two fingers on the anti-slip grooves 312110 and applies inward force to disengage the elastic buckle 3121 from the locking slot 4120, thereby unlocking the cleaning bracket 31 and allowing replacement of the cleaning bracket 31. The cleaning bracket 31 is provided with a lower limit wall 31220. When 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.

[0141] like Figure 7 As 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 inward. The elastic clip 3121 automatically deforms inward after hitting the insertion limit rib 412. Continue to press inward until it is in place, and the engaging protrusion 31212 of the elastic clip 3121 engages in the engaging groove 4120. The cleaning bracket 31 is installed in place, fixed on the turntable 41, and rotates with the turntable 41. When removing the cleaning bracket 31, place two fingers on the gripping section of the elastic clip 3121 of the cleaning bracket 31 and apply inward force to deform the elastic clip 3121, so that the engaging protrusion 31212 disengages from the engaging groove 4120. The cleaning bracket 31 is unlocked and can be removed.

[0142] After the cup cover assembly is assembled and the entire cup cover assembly is placed in the cup body 11, when the dust and gas separation device is working, air enters from the air inlet 1011 of the cyclone separation chamber 101, and rotates inside the cyclone separation chamber 101, driving the cleaning bracket 31 to rotate. The soft bristles on the inside clean the dust on the filter 22 while rotating, and the soft bristles on the outside clean the dust on the cup wall of the cyclone separation chamber 101 while rotating. The cleaning bracket 31 is rotated by the airflow, and the dust on the cup wall of the cyclone separation chamber 101 and the filter 22 is cleaned in real time when the dust and gas separation device is in use. This can keep the cup wall of the cyclone separation chamber 101 and the filter 22 clean, reducing the workload of the user in cleaning the dust cup 10. In addition, the cleaning bracket 31 is configured as a detachable structure, which is convenient for replacement after the bristles are worn, and provides a better user experience.

[0143] According to an embodiment of the present invention, on the other hand, a cleaning device is provided, comprising the dust and gas separation device of any one of the above embodiments.

[0144] In some embodiments, the cleaning equipment includes at least one of a mite remover, a vacuum cleaner, a sweeping robot, and a glass cleaning robot.

[0145] Preferably, in this embodiment, the cleaning device is a mite remover, and the dust and gas separation device is applied to the mite remover.

[0146] The present invention solves the problem of cleaning dust from the cup wall and filter screen 22 of the cyclone separation chamber 101 of the dust and gas separation device in the prior art. A rotatable turntable 41 is provided on the cup cover 12 of the dust cup 10, and a detachable cleaning bracket 31 is mounted on the turntable 41. Soft bristles are mounted on the inside and outside 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 removal device is working, air enters the cyclone separation chamber 101 from the inlet of the dust and gas separation device. The air rotates in the cyclone separation chamber 101, driving the cleaning bracket 31 to rotate. The inner soft bristles clean the dust on the filter screen 22 as they rotate, and the outer soft bristles clean the dust on the cup wall as they rotate. The airflow is used to rotate the cleaning bracket 31 without adding an additional power source. When the mite remover is in use, the dust on the cup wall of the cyclone separation chamber 101 and the filter 22 can be cleaned in real time, which can keep the cup wall and the filter 22 of the cyclone separation chamber 101 clean, reducing the workload of the user in cleaning the dust cup 10. In addition, the cleaning bracket 31 is set to a detachable structure, which is convenient for replacement after the bristles are worn, and the user experience is better.

[0147] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations shall fall within the scope of protection of the embodiments of the present application.
