Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0036] Reference below Figures 1-8 A centrifugal filter structure 100 according to an embodiment of the present invention is described. The centrifugal filter structure 100 can increase the filter area of ​​the centrifugal filter 2, thereby increasing the filter area, improving the filtration efficiency and filtration effect, and can more thoroughly separate pollutants from water, preventing pollutants from clogging the centrifugal filter 2, improving the purity of the filtered water, and thus improving the cleaning effect.

[0037] like Figures 1-8 As shown, the centrifugal filter structure 100 according to an embodiment of the present invention includes: a structural body 1, a centrifugal filter screen 2 and a drive assembly 3.

[0038] It should be noted that when using cleaning equipment for cleaning, pollutants are easily mixed into the water. The centrifugal filter structure 100 of this embodiment can separate and filter the pollutants to improve the purity of the water, so that the water can continue to be recycled for cleaning and the cleaning effect can be improved.

[0039] A centrifugal cavity 11 is formed in the structural body 1 . The structural body 1 is further provided with a centrifugal cavity inlet 12 and a centrifugal cavity outlet 13 . The centrifugal cavity inlet 12 and the centrifugal cavity outlet 13 are connected to the side wall of the centrifugal cavity 11 and are spaced apart and distributed along the circumference of the centrifugal cavity 11 .

[0040] That is, the interior of the structural body 1 is hollow to form a centrifugal chamber 11, and sewage can be separated by centrifugal force in the centrifugal chamber 11. The structural body 1 is also provided with a centrifugal chamber inlet 12 and a centrifugal chamber outlet 13, and the centrifugal chamber inlet 12 and the centrifugal chamber outlet 13 are connected to the side wall of the centrifugal chamber 11, that is, two openings are provided on the side wall of the centrifugal chamber 11, and sewage can enter the centrifugal chamber 11 through the centrifugal chamber inlet 12, and after centrifugal separation in the centrifugal chamber 11, the pollutants can be discharged from the centrifugal chamber 11 through the centrifugal chamber outlet 13.

[0041] Among them, the distribution position of the inlet of the centrifugal chamber 11 and the centrifugal chamber outlet 13 will affect the separation effect. Distributing the centrifugal chamber inlet 12 and the centrifugal chamber outlet 13 at intervals along the circumference of the centrifugal chamber 11 can prevent the separated pollutants from mixing into the water again, and can ensure that the pollutants are more evenly distributed in the centrifugal chamber 11 when entering the centrifugal chamber 11, reducing the situation of excessive or insufficient local distribution, thereby improving the filtration efficiency and effect.

[0042] Furthermore, the centrifugal filter screen 2 is installed in the centrifugal chamber 11, and the driving assembly 3 is used to drive the centrifugal filter screen 2 to rotate. The centrifugal filter screen 2 is spaced apart from the side wall of the centrifugal chamber 11 to jointly define a slag gap 14. A first drain port 21 is formed at the bottom of the centrifugal filter screen 2.

[0043] Specifically, the centrifugal filter 2 has filter holes that can filter pollutants and pass liquid. The shape of the centrifugal filter 2 is compatible with the shape of the centrifugal chamber 11, and its size is smaller than the size of the centrifugal chamber 11, so that the centrifugal filter 2 can be installed in the centrifugal chamber 11 and spaced a certain distance from the side wall of the centrifugal chamber 11 to jointly define a slag gap 14. The drive assembly 3 is used to provide power to drive the centrifugal filter 2 to rotate at high speed, and generate centrifugal force under the high-speed rotation of the centrifugal filter 2, so that the pollutants mixed in the sewage and the pollutants attached to the centrifugal filter 2 can be separated from the centrifugal filter 2 under the action of centrifugal force and located in the slag gap 14, and discharged from the centrifugal chamber outlet 13, thereby achieving effective filtration, making the filtered liquid purer, and the filtered liquid can be discharged from the first drain outlet 21 at the bottom of the centrifugal filter 2.

[0044] Among them, the inner diameter of the centrifugal filter 2 is d1, the inner diameter of the centrifugal chamber 11 is d2, the axial height of the centrifugal filter 2 is h1, the axial height of the centrifugal chamber 11 is h2, and they satisfy: d1 / d2≥1 / 2, h1 / h2≥1 / 2.

[0045] Specifically, the centrifugal chamber 11 and the centrifugal filter 2 are both cylindrical in shape, and the ratio of the inner diameter d1 of the centrifugal filter 2 to the inner diameter d2 of the centrifugal chamber 11 is d1 / d2 ≥ 1 / 2. That is, the radial dimension of the centrifugal filter 2 can be set to be greater than or equal to 1 / 2 times the inner diameter of the centrifugal chamber 11, and the radial dimension of the centrifugal filter 2 should be smaller than the radial dimension of the centrifugal chamber 11. The inner diameter d1 of the centrifugal filter 2 can be set as large as possible, but within the range of d1 / d2 ≥ 1 / 2. For example, d1 / d2 can be set to 0.5, 0.6, 0.7, etc., that is, the radial dimension of the centrifugal filter 2 can be 0.5, 0.6, 0.7, etc., of the inner diameter of the centrifugal chamber 11. This configuration increases the filter area of ​​the centrifugal filter 2, thereby increasing the filtration area and filtration efficiency, while also reducing the risk of clogging of the centrifugal filter 2.

[0046] The ratio of the axial height h1 of the centrifugal filter screen 2 to the axial height h2 of the centrifugal chamber 11 is h1 / h2≥1 / 2, that is, the axial height of the centrifugal filter screen 2 can be set to be greater than or equal to 1 / 2 times the axial height of the centrifugal chamber 11, and the axial height of the centrifugal filter screen 2 should be less than the axial height of the centrifugal chamber 11. The axial height of the centrifugal filter screen 2 can be set as high as possible, but within the range of h1 / h2≥1 / 2, for example, h1 / h2 can be set to 0.5, 0.55, 0.6, 0.65, 0.7, etc., that is, the axial height of the centrifugal filter screen 2 can be 0.5, 0.55, 0.6, 0.7, etc., that is, the axial height of the centrifugal filter screen 2 can be 0.5 times, 0.55 times, 0.6 times, 0.7 times, etc., of the axial height of the centrifugal chamber 11. This configuration not only increases the filter area of ​​the centrifugal filter screen 2 and improves filtration efficiency, but also facilitates a more even distribution of pollutants on the centrifugal filter screen 2 during the centrifugation process, improving the filtration effect and more thoroughly separating pollutants.

[0047] Therefore, by setting the proportional relationship between the inner diameter d1 of the centrifugal filter 2 and the inner diameter d2 of the centrifugal chamber 11 within the range of d1 / d2≥1 / 2, and setting the proportional relationship between the axial height h1 of the centrifugal filter 2 and the axial height h2 of the centrifugal chamber 11 within the range of h1 / h2≥1 / 2, the filter area of ​​the centrifugal filter 2 can be increased, thereby increasing the filtration area, improving the filtration efficiency and filtration effect, and more thoroughly separating the pollutants from the water, preventing the pollutants from clogging the centrifugal filter 2, improving the purity of the filtered water, and thus improving the cleaning effect.

[0048] It should be noted that the cleaning device of this embodiment can be any cleaning device that requires filtration and cleaning, such as a dishwasher, a cleaning machine, a washing machine, a floor scrubber, etc. For example, when the cleaning device is a dishwasher, it uses circulating water to wash dishes. During the dishwashing process, food residues are mixed into the water. By providing the centrifugal filter structure 100, the water and food residues can be separated by centrifugal filtration, and the filter area can be increased within a certain range, reducing costs, improving filtration efficiency and filtration effects, so that pollutants can be discharged in a timely manner, preventing pollutants from clogging the centrifugal filter 2, and at the same time, preventing residues from continuing to mix into the circulating water, making the filtered circulating water cleaner, thereby improving the purity of the circulating water and improving the cleaning effect of the dishwasher.

[0049] In some embodiments, the drive assembly 3 includes a drive member and a first rotating shaft 32. The first rotating shaft 32 is rotatably installed on the structural body 1, that is, the first rotating shaft 32 can rotate relative to the structural body 1. The first rotating shaft 32 is connected to the centrifugal filter 2 and is circumferentially limited to ensure that the first rotating shaft 32 and the centrifugal filter 2 can rotate synchronously and stably. The drive member is power-connected to the first rotating shaft 32, and the drive member is suitable for driving the first rotating shaft 32 to drive the centrifugal filter 2 to rotate.

[0050] That is to say, the driving member is used to provide power and transmit the power to the first rotating shaft 32 to drive the first rotating shaft 32 to rotate at high speed. When the first rotating shaft 32 rotates, it drives the centrifugal filter 2 to rotate at high speed. When the centrifugal filter 2 rotates at high speed, centrifugal force is generated and under the action of centrifugal force, the pollutants are gathered on the outside of the filter of the centrifugal chamber 11, that is, in the slag gap 14, and discharged through the centrifugal chamber outlet 13. At the same time, the centrifugal force can increase the water permeability of the centrifugal filter 2, so that water can be gathered in the centrifugal chamber 11 and discharged through the first drain port 21.

[0051] Specifically, if Figure 4 As shown, the drive assembly 3 includes a drive member and a first rotating shaft 32. The upper end surface of the centrifugal filter 2 is protruding inwardly and is provided with a through hole 22. The size of the through hole 22 is adapted to the size of the first rotating shaft 32, so that the first rotating shaft 32 can be penetrated in the through hole 22 and connected to the centrifugal filter 2, and the upper end head 321 of the first rotating shaft 32 is set to a polygonal cylindrical structure, that is, it is set to a non-round head structure to achieve circumferential limit cooperation with the centrifugal filter 2. Of course, circumferential limit cooperation can also be achieved through keyways, pins, screws, etc., so as to avoid relative rotation between the centrifugal filter 2 and the first rotating shaft 32, that is, the centrifugal filter 2 can rotate synchronously with the first rotating shaft 32, thereby ensuring the working stability of the centrifugal filter 2, wherein the drive member can be connected to the first rotating shaft 32 through other components to realize power transmission, which can drive the first rotating shaft 32 to rotate.

[0052] In some embodiments, the centrifugal filtration structure 100 also includes a first end cover 41, which is connected to the structural body 1, and the first end cover 41 is sealed at the upper end of the centrifugal chamber 11. The top of the centrifugal filter 2 is rotatably supported on the first end cover 41 through a bearing 71, and the upper end of the first rotating shaft 32 is connected to the centrifugal filter 2 and the lower end is rotatably supported on the bottom of the centrifugal chamber 11.

[0053] Specifically, if Figure 4 and Figure 5 As shown, the centrifugal filtration structure 100 is further provided with a first end cover 41, which is tightly connected to the structural main body 1 and is covered on the upper end of the centrifugal chamber 11 to seal the centrifugal chamber 11. A sealing ring 72 can also be provided to seal the contact surface between the first end cover 41 and the centrifugal chamber 11 to improve the sealing effect and prevent water from splashing or leaking during the centrifugal process, thereby ensuring the smooth progress of the centrifugal filtration process.

[0054] Among them, the top of the centrifugal filter 2 is rotatably supported on the first end cover 41 through a bearing 71, that is, the centrifugal filter 2 can rotate relative to the first end cover 41 to improve the separation efficiency. The provision of the bearing 71 can reduce the wear of the centrifugal filter 2, and the upper end of the first rotating shaft 32 is connected to the upper end of the centrifugal filter 2 to drive the centrifugal filter 2 to rotate synchronously. The lower end of the first rotating shaft 32 is rotatably supported on the bottom of the centrifugal chamber 11. For example, the lower end can be rotatably supported on the bottom of the centrifugal chamber 11 through a bearing 71, etc. In this way, the upper and lower ends of the first rotating shaft 32 are supported and fixed at the same time, which can ensure the stable rotation of the first rotating shaft 32, and then ensure the stable rotation of the centrifugal filter 2, thereby ensuring the feasibility of centrifugal filtration.

[0055] In some embodiments, the driving member is configured as a driving motor 31 . The driving motor 31 is provided with a driving gear 311 . The first rotating shaft 32 is provided with a first transmission gear 33 . The driving gear 311 is meshed with the first transmission gear 33 for transmission.

[0056] That is to say, when the drive motor 31 is started, it drives the drive gear 311 to rotate at a high speed, and the rotation of the drive gear 311 drives the first transmission gear 33 meshed with it to rotate, and then the rotation of the first transmission gear 33 can drive the first rotating shaft 32 to rotate synchronously, and the first rotating shaft 32 can continue to drive the centrifugal filter screen 2 to rotate at a high speed. Thus, the centrifugal filtration effect of the centrifugal filter screen 2 is achieved through the high-speed rotation of the centrifugal filter screen 2.

[0057] Specifically, if Figure 4 and Figure 5As shown, the driving member is constructed as a driving motor 31, which is arranged on the side of the centrifugal chamber 11 to improve the compactness of the structure and save space. A driving gear 311 is provided at the lower end of the driving motor 31, and a first transmission gear 33 is sleeved on the outer side of the lower end of the first rotating shaft 32, and the driving gear 311 is meshed with the first transmission gear 33.

[0058] In some embodiments, the outer peripheral wall of the centrifugal filter 2 is further provided with a first driving blade 21 , and the first driving blade 21 is located at the bottom of the slag gap 14 .

[0059] Specifically, a plurality of first drive blades 21 can be provided on the outer peripheral wall of the centrifugal filter 2 to improve the separation efficiency, and the first drive blades 21 are located at the bottom of the slag gap 14. In this way, when the first drive blades 21 rotate, they can push the water flow to flush the surface of the centrifugal filter 2, accelerate the separation of pollutants from the centrifugal filter 2, thereby preventing pollutants and the like from accumulating in the slag gap 14, clogging the centrifugal filter 2, and affecting the filtering effect.

[0060] Therefore, by setting the first driving blade 21 on the outer peripheral wall of the centrifugal filter 2, the outer surface of the centrifugal filter 2 can be cleaned to prevent pollutants from clogging the centrifugal filter 2, thereby improving the centrifugal filtration effect and facilitating the timely discharge of pollutants from the centrifugal cavity outlet 13, thereby improving the filtration efficiency.

[0061] The utility model also provides a cleaning device.

[0062] It should be noted that the cleaning device of this embodiment can be any cleaning device that requires filtering and cleaning, such as a dishwasher, a cleaning machine, a washing machine, a floor scrubber, etc.

[0063] The cleaning device according to the embodiment of the present invention is provided with the centrifugal filter structure 100 according to any one of the above embodiments, and further includes: a device body 5 and a filter cup 6 .

[0064] The main body 5 of the apparatus is formed with a cleaning space and a filter chamber 51. The cleaning space is used to accommodate or place items or liquids to be cleaned, and the filter chamber 51 is used to receive wastewater after preliminary cleaning for preliminary filtration. The filter chamber 51 is located below the cleaning space, and the bottom of the cleaning space is connected to the filter chamber 51. The sidewalls of the filter chamber 51 are connected to the sidewalls of the centrifugal chamber 11 through the centrifugal chamber inlet 12. This arrangement allows wastewater generated after cleaning items in the cleaning space to smoothly enter the filter chamber 51 for preliminary filtration, thereby filtering out larger contaminants. Smaller contaminants mixed with water can then continue to enter the centrifugal chamber 11 from the filter chamber 51 for secondary centrifugal filtration, thereby filtering out small contaminants and allowing them to be discharged from the centrifugal chamber outlet 13. This prevents contaminants from clogging the centrifugal filter 2, improves the purity of the circulating water, and prevents contaminants from re-contaminating items during the water circulation and washing process, resulting in incomplete cleaning. Furthermore, the amount of circulating water passing through the centrifugal filter 2 can be increased, thereby improving cleaning efficiency.

[0065] Among them, the equipment main body 5 and the equipment main body 5 are integrated into one body, which improves the integrity and stability of the cleaning equipment, simplifies the installation steps, and after the equipment main body 5 performs preliminary cleaning and filtration, secondary filtration can be performed in time.

[0066] The filter cup 6 is installed in the filter chamber 51, and the filter cup 6 is open to the cleaning space. That is, when water carrying pollutants flows from the cleaning space to the filter chamber 51 during cleaning, larger pollutants enter the filter cup 6 to be collected, thereby achieving primary filtration, while small pollutants enter the centrifugal chamber 11 together with water for secondary filtration.

[0067] Specifically, if Figure 1 and Figure 4 As shown, the device body 5 has a hollow area to form a filter chamber 51, and the filter cup 6 is constructed in a cylindrical shape, which is adapted to the shape and size of the filter chamber 51, so that the filter cup 6 can be installed in the filter chamber 51 and open upward. The filter cup 6 is provided with filter holes to filter pollutants.

[0068] The filter pore size of the filter cup 6 is d3, and satisfies: (d2-d1) / 2≥d3.

[0069] Specifically, it can be understood that, since the filter cup 6 needs to filter large-sized pollutants, the filter aperture d3 of the filter cup 6 is larger than the inner diameter d1 of the centrifugal filter screen 2, and the residual small-sized pollutants remaining after filtration by the filter cup 6 enter the centrifugal chamber 11. In other words, the filter cup 6 filters pollutants larger than the filter aperture d3 of the filter cup 6, while pollutants smaller than the filter aperture d3 of the filter cup 6 pass through the filter hole of the filter cup 6 into the centrifugal chamber 11 for centrifugal filtration. At this time, the pollutants entering the centrifugal chamber 11 will be isolated between the centrifugal filter screen 2 and the inner circumferential wall of the centrifugal chamber 11, that is, between the slag gap 14, under the action of centrifugal force. If the slag gap 14 is too small, the pollutants will accumulate and be blocked in the slag gap 14, thereby affecting the rotary filtration of the centrifugal filter screen 2. Therefore, it is necessary to set the size of the filter aperture d3 of the filter cup 6 to (d2-d1) / 2≥d3.

[0070] Therefore, by providing the filter cup 6 and the centrifugal filter structure 100, secondary filtration is formed to improve the cleaning effect. By setting the filter pore size d3 of the filter cup within the range of (d2-d1) / 2≥d3, the pollutants in the centrifugal chamber 11 can be prevented from being blocked in the slag gap 14 and affecting the centrifugal filtration effect.

[0071] In some embodiments, the opening width of the centrifugal chamber inlet 12 is d4, the opening width of the centrifugal chamber outlet 13 is d5, and the following conditions are satisfied: d4 ≥ d3, d5 ≥ d3.

[0072] That is, the opening width d4 of the centrifugal chamber inlet 12 is greater than or equal to the filter pore size d3 of the filter cup, and the opening width d5 ​​of the centrifugal chamber outlet 13 is greater than or equal to the filter pore size d3 of the filter cup.

[0073] By setting d4 ≥ d3, the small-sized pollutants remaining after filtration by the filter cup 6, i.e., pollutants smaller than the filter pore size d3 of the filter cup, can smoothly pass through the centrifugal chamber inlet 12 into the centrifugal chamber 11, preventing the pollutants from generating large resistance or being blocked at the centrifugal chamber inlet 12 when passing through the centrifugal chamber inlet 12, thereby affecting the centrifugal filtration process.

[0074] By setting d5≥d3, the pollutants after centrifugal filtration can leave the centrifugal chamber 11 through the centrifugal chamber outlet 13, preventing the pollutants from generating large resistance or being blocked at the centrifugal chamber outlet 13 when passing through the centrifugal chamber outlet 13, thereby improving the filtration efficiency.

[0075] Therefore, by setting the opening width d4 of the centrifugal chamber inlet 12 and the opening width d5 ​​of the centrifugal chamber outlet 13 to be greater than or equal to the filter aperture d3 of the filter cup, it can be ensured that pollutants can smoothly enter and leave the centrifugal chamber 11, thereby improving the filtration efficiency and maintaining the stable operation of the cleaning equipment, thereby improving the cleaning efficiency and ensuring the cleaning effect.

[0076] In some embodiments, the equipment body 5 is also formed with a filter residue cavity 52, and a rotatable slag filter screen 521 is provided in the filter residue cavity 52. ​​The slag filter screen 521 is spaced apart from the side wall of the filter residue cavity 52 to jointly define a slag collection gap 522. The centrifugal cavity outlet 13 is connected to the side wall of the slag collection gap 522. The equipment body 5 is also provided with a slag outlet 54. The slag outlet 54 and the centrifugal cavity outlet 13 are spaced apart and distributed in the circumferential direction of the filter residue cavity 52.

[0077] That is to say, the equipment body 5 is also provided with another hollow area to form a filter residue chamber 52, which is used to collect pollutants in the centrifugal chamber 11, so that the pollutants in the filter residue chamber 52 can be discharged in time, thereby further reducing the risk of clogging of the centrifugal filter 2. A slag filter screen 521 is provided in the residue chamber 52, and the slag filter screen 521 is separated from the side wall of the residue chamber 52 by a certain distance to form a slag collection gap 522. The centrifugal chamber outlet 13 is connected to the side wall of the slag collection gap 522, that is, the pollutants coming out of the centrifugal chamber 11 can enter the slag collection gap 522. In this way, the pollutants will be mixed with water under the centrifugal force of the centrifugal filter screen 2 and enter the slag collection gap 522 from the centrifugal chamber outlet 13. When the slag filter screen 521 rotates at high speed, centrifugal force will be generated to further filter the pollutants and improve the purity of the circulating water. At the same time, the pollutants attached to the slag filter screen 521 can be thrown out into the slag collection gap 522 under the action of centrifugal force to avoid clogging the slag filter screen 521, thereby improving the effect of collecting pollutants.

[0078] The slag outlet 54 is used to discharge pollutants collected in the slag collection chamber. Distributing the slag outlet 54 and the centrifugal chamber outlet 13 circumferentially apart from each other in the slag chamber 52 improves slag discharge efficiency while ensuring the structural strength of the slag chamber 52. Consequently, pollutants collected in the slag collection chamber can be discharged smoothly through the slag outlet 54.

[0079] Specifically, if Figure 3 As shown, the equipment body 5 is provided with a filter residue chamber 52, and a slag collection filter 521 is installed in the filter residue chamber 52. The centrifugal chamber 11 is adjacent to the filter residue chamber 52 and an opening connected to the centrifugal chamber outlet 13 is provided on the side wall of the filter residue chamber 52. Pollutants can enter the filter residue chamber 52 through this opening. A slag outlet 54 is also provided on the side wall of the filter residue chamber 52. The bottom wall of the filter residue chamber 52 can be tilted to make the position of the slag outlet 54 lower. In this way, pollutants can be prevented from accumulating in the slag collection gap 522, and the pollutants can be smoothly discharged from the slag outlet 54 by utilizing gravity and centrifugal action.

[0080] In some embodiments, the filtration aperture of the slag filter 521 is d6, the filtration aperture of the centrifugal filter 2 is d7, and the following conditions are satisfied: d6≤1mm, d7≤1mm, 2mm≤d3≤10mm.

[0081] For example, the filtering aperture d6 of the slag filter 521 can be set to 1mm, 0.9mm, 0.8mm, 0.7mm, 0.6mm, etc., and it is sufficient to be less than or equal to 1mm, so as to enable the slag filter 521 to filter pollutants larger than 1mm. The filtering aperture d7 of the centrifugal filter 2 can be set to 1mm, 0.9mm, 0.8mm, 0.7mm, 0.6mm, etc., and it is sufficient to be less than or equal to 1mm, so as to enable the centrifugal filter 2 to filter pollutants larger than 1mm. The filtering aperture d3 of the filter cup 6 can be set to 2mm, 4mm, 5.5mm, 7.5mm, 9mm, 10mm, etc., so as to enable the filter cup 6 to initially filter pollutants larger than 2mm≤d3≤10mm, and to continue to perform secondary filtration on pollutants smaller than 2mm≤d3≤10mm.

[0082] That is, the filtration aperture d6 of the residue filter 521 is less than or equal to the filtration aperture d3 of the filter cup 6, and the filtration aperture d7 of the centrifugal filter 2 is less than or equal to the filtration aperture d3 of the filter cup 6. In other words, the filter cup 6 isolates and filters pollutants with larger sizes, that is, it performs preliminary filtration on pollutants with a range greater than 2mm≤d3≤10mm. At the same time, the filter cup 6 cannot block the overall circulating water inlet, ensuring the smooth flow of the circulating water. After preliminary filtration by the filter cup 6, the residue filter 521 and the centrifugal filter 2 filter smaller pollutants and prevent smaller pollutants from mixing into the circulating water and affecting the filtering and cleaning effect.

[0083] In some embodiments, the outer peripheral wall of the slag collecting filter 521 is further provided with a second driving blade 5211 , and the second driving blade 5211 is located at the bottom of the slag collecting gap 522 .

[0084] Specifically, if Figure 3 As shown, a plurality of second driving blades 5211 can be provided on the outer peripheral wall of the slag filter 521 to improve the separation efficiency and the efficiency of collecting pollutants, and the second driving blades 5211 are located at the bottom of the slag gap 522. In this way, when the second driving blades 5211 rotate, they can push the water flow to flush the surface of the slag filter 521, so that the pollutants are further separated from the slag filter 521, thereby preventing the pollutants from clogging the slag filter 521 and affecting the filtering effect.

[0085] In practice, when slag discharge is required, the slag filter 521 rotates at high speed, and the second driving blade 5211 stirs the water in the slag filter chamber 52 to move, causing the pollutants to mix with the water and move, and the pollutants are discharged through the slag outlet 54.

[0086] Therefore, by arranging a second driving blade 5211 on the outer peripheral wall of the slag filter 521, the outer surface of the slag filter 521 can be cleaned to prevent pollutants from clogging the slag filter 521, thereby improving the centrifugal filtration effect, so that the pollutants can be mixed with water and discharged smoothly through the slag outlet 54, and the pollutants can be further filtered and separated to improve the purity of the circulating water.

[0087] In some embodiments, the slag filter 521 is connected to the second rotating shaft 53 , the driving assembly 3 is power-connected to the second rotating shaft 53 , and the driving assembly 3 is further used to drive the second rotating shaft 53 to drive the slag filter 521 to rotate.

[0088] Specifically, the drive assembly 3 is also used to provide power to the second rotating shaft 53 to drive the second rotating shaft 53 to rotate. In practice, when the drive assembly 3 is started, the second rotating shaft 53 is driven to rotate at high speed. When the second rotating shaft 53 rotates, the slag filter 521 is driven to rotate at high speed to generate centrifugal force.

[0089] In practice, Figure 6 and Figure 7 As shown, the second rotating shaft 53 may be sleeved with a second transmission gear 34, and the first transmission gear 33 is meshed with the second transmission gear 34. Thus, when the driving gear 311 drives the first transmission gear 33 to rotate, the first transmission gear 33 can also drive the second transmission gear 34 meshed with it to rotate, and the second transmission gear 34 rotates to drive the second rotating shaft 53 to rotate.

[0090] In some embodiments, a second end cover 42 is provided on the top of the residue filtering chamber 52 , and a second drain port 5212 is formed at the bottom of the residue collecting filter screen 521 .

[0091] Specifically, if Figure 6 As shown, the cleaning apparatus is further provided with a second end cap 42, which is tightly connected to the apparatus body 5 and covers the upper end of the residue chamber 52 to seal the residue chamber 52. A sealing ring 72 can also be provided to seal the contact surface between the second end cap 42 and the residue chamber 52, thereby improving the sealing effect and preventing water from splashing or leaking during the centrifugation process, thereby ensuring the smooth progress of the centrifugal filtration process. A second drain port 5212 is formed at the bottom of the residue filter screen 521, through which filtered water in the residue chamber 52 can be discharged.

[0092] In some embodiments, the filter cup 6 is rotatably installed in the filter cavity 51 , and the rotation direction of the filter cup 6 is the same as the rotation direction of the centrifugal filter screen 2 .

[0093] That is to say, the filter cup 6 can rotate in the filter chamber 51, and the rotation direction is the same as that of the centrifugal filter 2. In this way, when the filter cup 6 and the centrifugal filter 2 rotate, centrifugal force can be generated, so that the pollutants in the filter chamber 51 and the water enter the centrifugal chamber 11 tangentially under the action of centrifugal force for further filtration.

[0094] It should be noted that the filter cup 6 and the residue filter screen 521 can be configured to be detachably installed in the filter chamber 51 and the residue chamber 52. In this way, the filter cup 6 can be conveniently removed from the filter chamber 51 and the residue filter screen 521 can be conveniently removed from the residue chamber 52, thereby facilitating the maintenance and cleaning of the filter cup 6 and the residue filter screen 521.
