[0038] The following refers to Figures 1 - 9 Describe the centrifugal filtration structure 100 according to an embodiment of the present utility model. The centrifugal filtration structure 100 can make the separation of pollutants and water more thorough, improve the purity of the filtered water, thereby improving the cleaning effect, and prevent pollutants from adhering to the centrifugal filter screen 2 and blocking the centrifugal filter screen 2, realizing the automatic cleaning of the centrifugal filter screen 2, and improving the filtration efficiency and filtration effect.

[0039] As Figures 1 - 9 shown, the centrifugal filtration structure 100 according to an embodiment of the present utility model includes: a structure main body 1, a centrifugal filter screen 2, and a driving assembly 3.

[0040] It should be noted that when using a cleaning device for cleaning, pollutants are likely to be mixed into the water. The centrifugal filtration structure 100 of this embodiment can effectively separate and filter the pollutants, not only improving the cleanliness of the centrifugal filter screen 2, but also improving the purity of the water, so that the water can be recycled for cleaning, and the cleaning effect is improved.

[0041] A centrifugal chamber 11 is formed inside the structure main body 1. The structure main body 1 is further provided with a centrifugal chamber inlet 12 and a centrifugal chamber outlet 13. The centrifugal chamber inlet 12 and the centrifugal chamber outlet 13 are communicated with the side wall of the centrifugal chamber 11 and are spaced apart along the circumferential direction of the centrifugal chamber 11.

[0042] That is to say, the interior of the structural body 1 is hollow to form a centrifugal chamber 11. Sewage can be separated under the action of 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. The centrifugal chamber inlet 12 and the centrifugal chamber outlet 13 are communicated with the side wall of the centrifugal chamber 11. That is, two openings are provided on the side wall of the centrifugal chamber 11. Sewage can enter the centrifugal chamber 11 through the centrifugal chamber inlet 12. After centrifugal separation in the centrifugal chamber 11, pollutants can be discharged from the centrifugal chamber 11 through the centrifugal chamber outlet 13.

[0043] Among them, the distribution positions of the centrifugal chamber inlet 12 and the centrifugal chamber outlet 13 will affect the separation effect. Spacing the centrifugal chamber inlet 12 and the centrifugal chamber outlet 13 along the circumferential direction 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 filtration effect.

[0044] Furthermore, the centrifugal filter screen 2 is installed in the centrifugal chamber 11. 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 discharge gap 14. A first circulating water outlet 21 is formed at the bottom of the centrifugal filter screen 2.

[0045] Specifically, the centrifugal filter screen 2 has filter holes, which can filter pollutants and allow liquids to pass through. The shape of the centrifugal filter screen 2 is adapted to the shape of the centrifugal chamber 11. It can be constructed as a cylindrical shape, and its size is smaller than that of the centrifugal chamber 11. Thus, the centrifugal filter screen 2 can be installed in the centrifugal chamber 11 and spaced apart from the side wall of the centrifugal chamber 11 by a certain distance to jointly define a slag discharge gap 14. The driving assembly 3 is used to provide power to drive the centrifugal filter screen 2 to rotate at a high speed, and a centrifugal force is generated under the high-speed rotation of the centrifugal filter screen 2. Thus, the pollutants mixed in the sewage and the pollutants attached to the centrifugal filter screen 2 can be separated from the centrifugal filter screen 2 under the action of the centrifugal force and located in the slag discharge gap 14, and discharged from the centrifugal chamber outlet 13, thereby realizing effective filtration, making the filtered liquid purer, and the filtered liquid can be discharged from the first circulating water outlet 21 at the bottom of the centrifugal filter screen 2.

[0046] In practice, the centrifugal filter screen 2 can be set to be detachably installed in the centrifugal chamber 11. In this way, it is convenient to take out the centrifugal filter screen 2 from the centrifugal chamber 11, which is beneficial to its maintenance and cleaning.

[0047] Thus, by arranging a centrifugal filter screen 2 in the centrifugal chamber 11, driving the centrifugal filter screen 2 to rotate at a high speed by the driving motor 31 to generate centrifugal force, and effectively separating and filtering pollutants under the action of the centrifugal force, not only can the pollutants and water be separated more thoroughly, the purity of the filtered water be improved, thereby improving the cleaning effect, but also the pollutants can be prevented from adhering to the centrifugal filter screen 2 and blocking the centrifugal filter screen 2, thus affecting the filtration efficiency and filtration effect. That is, the centrifugal filter screen 2 can not only effectively filter pollutants, but also perform automatic cleaning without manual cleaning, solving the problems of secondary pollution caused by the traditional cleaning of the filter screen with a scraper, squeezing the pollutants and the filter screen, resulting in pollutants adhering to the filter screen and partial penetration through the filter screen, and the problem of squeezing the filter screen affecting the performance and service life of the filter screen.

[0048] It should be noted that the cleaning device in this embodiment can be any cleaning device that requires filtration and cleaning, such as a dishwasher, a cleaning machine, a washing machine, a floor washer, etc. For example, when the cleaning device is a dishwasher, circulating water is used for dishwashing. During the dishwashing process, food residues are mixed into the water. By arranging the centrifugal filtration structure 100, the water and food residues can be centrifugally filtered and separated, improving the filtration efficiency and filtration effect, so that the food residues can be discharged in time, preventing the food residues from blocking the centrifugal filter screen 2. At the same time, it prevents the food residues from continuing to mix into the circulating water, making the filtered circulating water cleaner, thereby improving the purity of the circulating water and the cleaning effect of the dishwasher.

[0049] According to the centrifugal filtration structure 100 of the embodiment of the present invention, by arranging a centrifugal filter screen 2 in the centrifugal chamber 11, driving the centrifugal filter screen 2 to rotate at a high speed by the driving motor 31 to generate centrifugal force, and effectively separating and filtering pollutants under the action of the centrifugal force, the pollutants and water can be separated more thoroughly, the purity of the filtered water can be improved, thereby improving the cleaning effect, and the pollutants can be prevented from adhering to the centrifugal filter screen 2 and blocking the centrifugal filter screen 2, realizing the automatic cleaning of the centrifugal filter screen 2 and improving the filtration efficiency and filtration effect.

[0050] In some embodiments, the centrifugal filtration structure 100 further includes a flow channel plate 8, and the flow channel plate 8 is connected to the structural main body 1.

[0051] Specifically, the flow channel plate 8 is used to realize the circulating flow of the filtered water and the fixed installation of the driving assembly 3. Connecting the flow channel plate 8 to the structural main body 1 can enable the water filtered in the centrifugal chamber 11 to flow through the flow channel plate 8 into the circulation pump 9 for circulation.

[0052] Furthermore, the driving assembly 3 includes a driving member and a first rotating shaft 32. The driving member is installed on the flow channel plate 8. One end of the first rotating shaft 32 extends into the centrifugal chamber 11, and the other end of the first rotating shaft 32 extends into the flow channel plate 8 and is power-connected to the driving member.

[0053] Specifically, asFigure 4 As shown, the structural body 1 is located above, and the flow channel plate 8 is located below. The flow channel plate 8 is connected to the structural body 1 as a whole. The driving member is fixedly installed on the flow channel plate 8 and is located on the side of the centrifugal chamber 11. In this way, not only the occupied space of the driving member is saved, the compactness of the centrifugal filtration structure 100 is improved, but also water is prevented from entering the driving member and affecting its operation.

[0054] Among them, the upper end of the first rotating shaft 32 extends into the centrifugal chamber 11 and is connected to the centrifugal filter screen 2. The lower end of the first rotating shaft 32 extends into the flow channel plate 8 and is power-connected to the driving member through other components. Thus, the positioning and installation of the first rotating shaft 32 are realized. In practice, the driving member can provide power and transmit the power to the first rotating shaft 32 to drive the first rotating shaft 32 to rotate at a high speed.

[0055] In some embodiments, the flow channel plate 8 is formed with a drainage channel 81. One end of the drainage channel 81 is formed with a water inlet 811. The water inlet 811 is located at the bottom of the centrifugal filter screen 2 and is communicated with the first circulating water outlet 21.

[0056] That is to say, the drainage channel 81 is communicated with the centrifugal chamber 11 through the water inlet 811 and the first circulating water outlet 21. In this way, the water filtered in the centrifugal chamber 11 can flow through the first circulating water outlet 21 and the water inlet 811 to the drainage channel 81, and then flow through the drainage channel 81 to the circulating pump 9 for circulating flow.

[0057] Specifically, as Figure 8 shown, the drainage channel 81 is formed inside the flow channel plate 8. The upper end of the drainage channel 81 is formed with a water inlet 811. The water inlet 811 is open upward and is located at the bottom of the centrifugal filter screen 2 to be opposite to and communicated with the first circulating water outlet 21.

[0058] In some embodiments, the first rotating shaft 32 sequentially passes through the water inlet 811 and the first circulating water outlet 21. The upper end of the first rotating shaft 32 extends into the centrifugal chamber 11 and is connected to the centrifugal filter screen 2. The lower end of the first rotating shaft 32 penetrates the inner wall of the water inlet 811 to extend into the flow channel plate 8 and is power-connected to the driving member.

[0059] Specifically, as Figure 8As shown, the first rotating shaft 32 passes through the first circulating water outlet 21 and the water inlet 811 from top to bottom in sequence. The upper end of the first rotating shaft 32 extends into the centrifugal chamber 11 and is connected to the centrifugal filter screen 2. In this way, the first rotating shaft 32 can rotate synchronously with the centrifugal filter screen 2. Among them, the water inlet 811 is communicated with the drainage channel 81, and the drainage channel 81 is located below the water inlet 811. The lower end of the first rotating shaft 32 penetrates the inner wall of the water inlet 811 and extends into the flow channel plate 8 to be power-connected with the driving member. Thus, the positioning installation of the first rotating shaft 32 and the power transmission from the driving member to the centrifugal filter screen 2 are realized, and the stable operation of the first rotating shaft 32 can be ensured. In practice, when the driving member drives the first rotating shaft 32 to rotate at a high speed, the first rotating shaft 32 can drive the centrifugal filter screen 2 to rotate at a high speed, thereby generating centrifugal force.

[0060] In some embodiments, a seal 321 is further provided outside the first rotating shaft 32. A through-hole 8111 is provided on the inner wall of the water inlet 811, and the seal 321 is in sealing abutment with the circumferential edge of the through-hole 8111.

[0061] Specifically, the shape and size of the seal 321 are adapted to those of the through-hole 8111. Thus, the seal 321 can be installed in the through-hole 8111 for sealing abutment and cooperation with the through-hole 8111. And through the sealing abutment of the seal 321 with the circumferential edge of the through-hole 8111, the gap between the seal 321 and the through-hole 8111 can be effectively closed, thereby preventing liquid leakage at the water inlet.

[0062] In practice, as Figure 4 and Figure 5 shown, the seal 321 can be configured as a ring, arranged in the through-hole 8111 for sealing abutment with the circumferential edge of the through-hole 8111. Among them, the lower end of the first rotating shaft 32 is rotatably supported in the flow channel plate 8 through a bearing member 71. The seal 321 can also be configured as an oil seal, arranged above the bearing member 71. In this way, not only can it play a sealing role, but also it can lubricate the bearing member 71. And a limiting member can be further arranged outside the first rotating shaft 32. The limiting member can be configured as a retaining ring 72, sleeved outside the first rotating shaft 32 to limit the axial movement and offset of the first rotating shaft 32, and at the same time play a sealing role. Thus, the seal 321 and the retaining ring 72 can play a double-layer sealing role, ensuring the stable and reliable operation of the first rotating shaft 32.

[0063] In some embodiments, an installation space 83 is formed in the flow channel plate 8. The driving member is configured as a driving motor 31. The motor shaft 311 of the driving motor 31 extends into the installation space 83. A driving gear 312 is provided outside the motor shaft 311. A first transmission gear 33 is sleeved outside the first rotating shaft 32, and the driving gear 312 is in meshing transmission with the first transmission gear 33.

[0064] Specifically, as Figure 4As shown, the inside of the flow channel plate 8 is hollow to form an installation space 83. The driving member is configured as a driving motor 31. The motor shaft 311 of the driving motor 31 extends downward and extends into the installation space 83. A driving gear 312 is sleeved outside the motor shaft 311. The lower end of the first rotating shaft 32 extends into the installation space 83 and a first transmission gear 33 is sleeved outside. And the driving gear 312 meshes with the first transmission gear 33.

[0065] With such a setting, in practice, when the driving motor 31 is started, its motor shaft 311 rotates at a high speed to drive the driving gear 312 to rotate at a high speed. By the rotation of the driving gear 312, the first transmission gear 33 meshing therewith is driven to rotate. Further, the rotation of the first transmission gear 33 can drive the first rotating shaft 32 to rotate synchronously. The first rotating shaft 32 can continue to drive the centrifugal filter screen 2 to rotate at a high speed. Thus, the centrifugal filtering function of the centrifugal filter screen 2 is realized through the high-speed rotation of the centrifugal filter screen 2.

[0066] In the actual design, as Figure 6 shown, the flow channel plate 8 can be configured to include an upper plate 81 and a lower plate 82 that are detachably connected. The upper plate 81 and the lower plate 82 are connected to jointly define the installation space 83. In this way, it is beneficial to install the driving motor 31, the first rotating shaft 32, the driving gear 312 and the first transmission gear 33. After the upper plate 81 is installed, the lower plate 82 is then covered on the upper plate 81.

[0067] In some embodiments, the centrifugal filtering structure 100 further includes a first end cover 41. The first end cover 41 is connected to the structure main body 1, and the first end cover 41 seals the upper end of the centrifugal chamber 11. The top of the centrifugal filter screen 2 is rotatably connected to the first end cover 41 through a bearing member 71.

[0068] Specifically, as Figure 4 and Figure 6 shown, the centrifugal filtering structure 100 is further provided with a first end cover 41. The first end cover 41 is closely connected to the structure main body 1 and covers the upper end of the centrifugal chamber 11 to seal the centrifugal chamber 11. A sealing ring can also be provided to seal the contact surface between the first end cover 41 and the centrifugal chamber 11, improve the sealing effect, and prevent water and the like from splashing or leaking during the centrifugation process, thereby ensuring the smooth progress of the centrifugal filtering process.

[0069] Among them, the top of the centrifugal filter screen 2 is rotatably supported on the first end cover 41 through the bearing member 71, that is, the centrifugal filter screen 2 can rotate relative to the first end cover 41 to improve the separation efficiency. The setting of the bearing member 71 can reduce the wear of the centrifugal filter screen 2, and the upper end of the first rotating shaft 32 is connected to the upper end of the centrifugal filter screen 2 to drive the centrifugal filter screen 2 to rotate synchronously.

[0070] In some embodiments, a first driving blade 21 is further provided on the outer peripheral wall of the centrifugal filter screen 2, and the first driving blade 21 is located at the bottom of the slag passing gap 14.

[0071] Specifically, a plurality of first driving blades 21 can be arranged on the outer peripheral wall of the centrifugal filter screen 2 to improve the separation efficiency. Moreover, the first driving blade 21 is located at the bottom of the slag passing gap 14. In this way, when the first driving blade 21 rotates, it can push the water flow to wash the surface of the centrifugal filter screen 2, accelerating the separation of pollutants from the centrifugal filter screen 2. Thus, it can prevent pollutants and the like from accumulating in the slag passing gap 14, blocking the centrifugal filter screen 2 and affecting the filtering effect. Moreover, it can make the centrifugal filter screen 2 cleaner and more thorough.

[0072] Therefore, by arranging the first driving blade 21 on the outer peripheral wall of the centrifugal filter screen 2, the outer surface of the centrifugal filter screen 2 can be cleaned, preventing pollutants from blocking the centrifugal filter screen 2. Thus, the centrifugal filtering effect can be improved, and it is beneficial for pollutants to be discharged from the centrifugal chamber outlet 13 in a timely manner, thereby improving the filtering efficiency.

[0073] The present utility model also proposes a cleaning device.

[0074] Among them, it should be noted that the cleaning device in this embodiment can be any cleaning device that requires filtration and cleaning, such as a dishwasher, a cleaning machine, a washing machine, a floor washer, etc.

[0075] The cleaning device according to the embodiment of the present utility model is provided with the centrifugal filtering structure 100 of any one of the above embodiments, and further includes: a device main body 5 and a filtering cup 6.

[0076] The device main body 5 forms a cleaning space and a filtering chamber 51. The cleaning space is used to accommodate or place items or liquids to be cleaned, etc. The filtering chamber 51 is used to receive the sewage after preliminary cleaning for preliminary filtration. Among them, the filtering chamber 51 is located below the cleaning space, and the bottom of the cleaning space is communicated with the filtering chamber 51. The side wall of the filtering chamber 51 and the side wall of the centrifugal chamber 11 are communicated through the centrifugal chamber inlet 12. With such a setting, the sewage generated after cleaning the items in the cleaning space can smoothly enter the filtering chamber 51 for preliminary filtration of the sewage, that is, pollutants with larger sizes can be filtered out, while pollutants with smaller sizes and water can continue to enter the centrifugal chamber 11 for secondary centrifugal filtration, so that pollutants with small sizes can be filtered out and discharged from the centrifugal chamber outlet 13, preventing pollutants from blocking the centrifugal filter screen 2, improving the purity of the circulating water, avoiding the pollutants from contaminating the items again when the water is circulated for cleaning, resulting in incomplete cleaning, and increasing the amount of water passing through the centrifugal filter screen 2 by the circulating water, thereby improving the cleaning efficiency.

[0077] Among them, the device main body 5 is integrally provided with the device main body 5, so that the integrity and stability of the cleaning device are improved, the installation steps are simplified, and after the device main body 5 is preliminarily cleaned and filtered, secondary filtration can be carried out in a timely manner.

[0078] The filter cup 6 is installed in the filter chamber 51, and the filter cup 6 is open towards the cleaning space. That is to say, when water carries pollutants and flows down from the cleaning space to the filter chamber 51 during cleaning, pollutants with larger sizes enter the filter cup 6 for collection, so as to achieve preliminary filtration, while pollutants with smaller sizes and water enter the centrifugal chamber 11 together for secondary filtration.

[0079] Specifically, as Figure 1 shown, the device main body 5 has a hollow area to form the filter chamber 51. The filter cup 6 is configured in a cylindrical shape and 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 is open upward. The filter cup 6 is provided with filter holes to filter pollutants.

[0080] Thus, by providing the filter cup 6 and the centrifugal filtration structure 100, secondary filtration is formed to improve the cleaning effect.

[0081] According to the cleaning device of the embodiment of the present utility model, a centrifugal filter screen 2 is arranged in the centrifugal chamber 11. The driving motor 31 is used to drive the centrifugal filter screen 2 to rotate at a high speed to generate centrifugal force, and under the action of the centrifugal force, pollutants can be effectively separated and filtered, so that pollutants and water can be more thoroughly separated, the purity of the filtered water is improved, thereby improving the cleaning effect, and preventing pollutants from adhering to the centrifugal filter screen 2 and blocking the centrifugal filter screen 2, realizing the automatic cleaning of the centrifugal filter screen 2, and improving the filtration efficiency and filtration effect.

[0082] In some embodiments, the device main body 5 further forms a filter residue chamber 52. A rotatable slag collection filter screen 521 is arranged in the filter residue chamber 52. The slag collection filter screen 521 is spaced apart from the side wall of the filter residue chamber 52 to jointly define a slag collection gap 522. The centrifugal chamber outlet 13 is communicated with the side wall of the slag collection gap 522. The device main body 5 is further provided with a slag outlet 54. The slag outlet 54 and the centrifugal chamber outlet 13 are distributed at intervals in the circumferential direction of the filter residue chamber 52.

[0083] That is to say, the device main body 5 is also provided with another hollow area to form a filter residue chamber 52. The filter residue chamber 52 is used to collect pollutants in the centrifugal chamber 11, so that the pollutants in the centrifugal chamber 11 can be discharged in time, thereby further reducing the risk of blockage of the centrifugal filter screen 2. A slag collection filter screen 521 is arranged in the filter residue chamber 52, and the slag collection filter screen 521 is spaced apart from the side wall of the filter residue chamber 52 by a certain distance to form a slag collection gap 522. The centrifugal chamber outlet 13 is communicated with the side wall of the slag collection gap 522, that is, the pollutants coming out of the centrifugal chamber 11 can enter the filter residue chamber 52. In this way, the pollutants will be mixed with water under the action of 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 collection filter screen 521 rotates at a high speed, a 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 collection filter screen 521 can be thrown out into the slag collection gap 522 under the action of the centrifugal force, avoiding blockage of the slag collection filter screen 521, thereby improving the effect of collecting pollutants.

[0084] Among them, the slag outlet 54 is used to discharge the pollutants collected in the filter residue chamber 52. Spacing the slag outlet 54 and the centrifugal chamber outlet 13 circumferentially in the filter residue chamber 52 can improve the slag discharge efficiency and ensure the structural strength of the filter residue chamber 52 at the same time. Thus, the pollutants finally collected in the filter residue chamber 52 can be smoothly discharged through the slag outlet 54.

[0085] Specifically, as Figure 1 and Figure 3 shown, the device main body 5 is provided with a filter residue chamber 52. A slag collection filter screen 521 is installed in the filter residue chamber 52. The centrifugal chamber 11 is adjacent to the filter residue chamber 52, and an opening communicating with 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 inclined so that the position of the slag outlet 54 is lower. In this way, it can prevent pollutants from accumulating in the slag collection gap 522, and make the pollutants smoothly discharged from the slag outlet 54 by using gravity and centrifugal force.

[0086] In some embodiments, a second driving blade 5211 is further provided on the outer peripheral wall of the slag collection filter screen 521, and the second driving blade 5211 is located at the bottom of the slag collection gap 522.

[0087] Specifically, as Figure 3 shown, a plurality of second driving blades 5211 can be provided on the outer peripheral wall of the slag collection filter screen 521 to improve the separation efficiency and the efficiency of collecting pollutants. And the second driving blade 5211 is located at the bottom of the slag collection gap 522. In this way, when the second driving blade 5211 rotates, it can push the water flow to wash the surface of the slag collection filter screen 521, so that the pollutants are further separated from the slag collection filter screen 521, thereby preventing the pollutants from blocking the slag collection filter screen 521 and affecting the filtering effect.

[0088] In practice, when slag discharge is required, the slag collection filter screen 521 rotates at a high speed, and the second driving blades 5211 stir the water movement in the slag filtering chamber 52, so that the pollutants and water are mixed and move, and the pollutants are discharged through the slag outlet 54.

[0089] Thus, by providing the second driving blades 5211 on the outer peripheral wall of the slag collection filter screen 521, the outer surface of the slag collection filter screen 521 can be cleaned, preventing the pollutants from clogging the slag collection filter screen 521, thereby improving the centrifugal filtration effect, enabling the pollutants to be mixed with water and move smoothly through the slag outlet 54, and further filtering and separating the pollutants to improve the purity of the circulating water.

[0090] In some embodiments, the slag collection filter screen 521 is connected to a second rotating shaft 53, and the driving assembly 3 is power-connected to the second rotating shaft 53. The driving assembly 3 is further configured to drive the second rotating shaft 53 to drive the slag collection filter screen 521 to rotate.

[0091] Specifically, the driving assembly 3 is further configured to provide power to the second rotating shaft 53 to drive the second rotating shaft 53 to rotate. In practice, when the driving assembly 3 is started, it drives the second rotating shaft 53 to rotate at a high speed. When the second rotating shaft 53 rotates, it drives the slag collection filter screen 521 to rotate at a high speed to generate centrifugal force.

[0092] In practice, as Figure 8 shown, the upper end of the second rotating shaft 53 extends into the slag filtering chamber 52 and is connected to the slag collection filter screen 521. In this way, the second rotating shaft 53 can rotate synchronously with the slag collection filter screen 521. The lower end of the second rotating shaft 53 extends into the installation space 83 of the flow channel plate 8 and is sleeved with a second transmission gear 34 on the outside. The first transmission gear 33 meshes with the second transmission gear 34. Thus, when the driving gear 312 drives the first transmission gear 33 to rotate, the first transmission gear 33 can also drive the second transmission gear 34 meshing with it to rotate, and the second transmission gear 34 rotates to drive the second rotating shaft 53 to rotate.

[0093] In some embodiments, a second end cover 42 is provided at the top of the slag filtering chamber 52, and a second circulating water outlet 5212 is formed at the bottom of the slag collection filter screen 521.

[0094] Specifically, as Figure 7 and Figure 8As shown, the cleaning device is further provided with a second end cover 42. The second end cover 42 is tightly connected to the device main body 5 and covers the upper end of the filter residue chamber 52 to block the filter residue chamber 52. A sealing ring can also be provided to seal the contact surface between the second end cover 42 and the filter residue chamber 52, improve the sealing effect, and prevent water and the like from splashing or leaking during centrifugation, thereby ensuring the smooth progress of the centrifugal filtration process. Among them, a second circulating water outlet 5212 is formed at the bottom of the slag collection filter screen 521, that is, the water filtered in the slag collection chamber 52 can be discharged from the second circulating water outlet 5212.

[0095] In actual design, as Figure 8 shown, the second circulating water outlet 5212 can be communicated with the drainage channel 81. Thus, the water further centrifugally filtered in the filter residue chamber 52 can flow into the drainage channel 81, and be mixed with the water filtered in the centrifugal chamber 11 and then flow into the circulation pump 9 for circulating flow.

[0096] In some embodiments, the filter cup 6 is rotatably installed in the filtration chamber 51, and the rotation direction of the filter cup 6 is the same as that of the centrifugal filter screen 2.

[0097] That is to say, the filter cup 6 can rotate in the filtration chamber 51 and has the same rotation direction as the centrifugal filter screen 2. In this way, when the filter cup 6 and the centrifugal filter screen 2 rotate, a centrifugal force can be generated, so that the pollutants and water in the filtration chamber 51 enter the centrifugal chamber 11 tangentially under the action of the centrifugal force for further filtration.

[0098] Among them, it should be noted that the filter cup 6 and the slag collection filter screen 521 can both be set to be detachably installed in the filtration chamber 51 and the filter residue chamber 52. In this way, it is convenient to take out the filter cup 6 from the filtration chamber 51 and take out the slag collection filter screen 521 from the filter residue chamber 52, thereby facilitating the maintenance and cleaning of the filter cup 6 and the slag collection filter screen 521.
