[0054] Among them, the rotating assembly 70 is arranged between the centrifugal filter screen 20 and the cover plate 60. The rotating assembly 70 is used to rotatably connect the centrifugal filter screen 20 to the cover plate 60.

For example, the second sub-component 72 and the cover plate 60 are in interference fit or are threadedly connected, so that the second sub-component 72 and the cover plate 60 remain relatively stationary.

[0055] In the above solution, by providing the rotating assembly 70, the rotating assembly 70 is used to connect the centrifugal filter screen 20 and the cover plate 60. The first sub-component 71 is fixedly connected to the centrifugal filter screen 20, and the second sub-component 72 is fixedly connected to the cover plate 60. When the cover plate 60 is disassembled, the centrifugal filter screen 20 follows the cover plate 60, thereby simplifying the disassembly steps of the centrifugal filter screen 20. For example, when the cover plate 60 is lifted, the centrifugal filter screen 20 is lifted together, and there is no need to perform a separate operation on the centrifugal filter screen 20, simplifying the steps.

[0061] Among them, the positioning protrusion 62 can be provided on the cover plate 60, and the corresponding positioning groove 18 is provided on the base 10, or the positioning protrusion 62 is provided on the base 10, and the corresponding positioning groove 18 is provided on the cover plate 60. The positioning protrusion 62 is inserted through the positioning groove 18 to fix the cover plate 60 on the base 10.

[0062] In the above solution, the cover plate 60 is fixed on the base 10 through the cooperation of the positioning protrusion 62 and the positioning groove 18. The structure is simple, and the positioning protrusion 62 and the positioning groove 18 are detachably engaged, which facilitates the disassembly of the cover plate 60.

[0063] Specifically, the positioning groove 18 communicates with a guiding opening 182 suitable for guiding the insertion of the positioning protrusion 62; or, the positioning protrusion 62 is configured as an elastic member, and the positioning protrusion 62 undergoes elastic deformation and is pressed into the positioning groove 18.

The positioning protrusion 62 is inserted into the guiding groove 181 from the guiding opening 182 and then moves into the positioning groove 18.

[0066] In the above solution, by providing the guiding groove 181 to guide the positioning protrusion 62 and guiding the movement of the positioning protrusion 62, the disassembly of the cover plate 60 is made more reliable and the stability is improved.

[0067] Specifically, there are a plurality of positioning grooves 18, and the plurality of positioning grooves 18 are arranged at intervals along the circumferential direction of the centrifugal chamber 11, so that the cover plate 60 contacts the base 10 at multiple parts, improving the reliability.

[0070] In the above solution, by providing the threaded protrusion and the threaded groove, the cover plate 60 is threadedly connected to the base 10, enabling quick disassembly and installation, and improving the convenience and stability.

[0071] Referring to Figure 1 , in some embodiments, the centrifugal filter screen 20 is provided with a disturbing member 22, and the disturbing member 22 is arranged on the outer peripheral wall of the centrifugal filter screen 20 to disturb the sewage when the centrifugal filter screen 20 rotates.

[0072] Among them, the disturbing member 22 is arranged on the outer peripheral wall of the centrifugal filter screen 20, the centrifugal filter screen 20 drives the disturbing member 22 to rotate, the disturbing member 22 disturbs the sewage, and the sewage drives the dirt, preventing the dirt from depositing in the centrifugal chamber 11.

[0073] In the above solution, by providing the disturbing member 22 on the outer peripheral wall of the centrifugal filter screen 20 and using the disturbing member 22 to disturb the dirt, the dirt is prevented from depositing in the centrifugal chamber 11, reducing the cleaning frequency.

[0074] Specifically, sewage exists in the centrifugal chamber 11, the disturbing member 22 disturbs the sewage, and the contaminants in the sewage float up, thus avoiding sedimentation.

[0075] In some embodiments, the disturbing member 22 is disposed at the bottom end of the centrifugal filter screen 20.

[0076] Among them, the disturbing member 22 is located at the bottom end of the centrifugal filter screen 20, and the disturbing member 22 is close to the bottom of the centrifugal chamber 11.

[0077] In the above solution, by disposing the disturbing member 22 at the bottom end of the centrifugal filter screen 20, a larger range of the centrifugal chamber 11 is affected, increasing the disturbing effect.

[0078] In some embodiments, the inner wall of the centrifugal chamber 11 is configured as a smooth surface.

[0079] Among them, the inner wall of the centrifugal chamber 11 is configured as a smooth surface, that is to say, there are no protrusions on the inner wall of the centrifugal chamber 11, and the sewage can flow smoothly in the centrifugal chamber 11.

[0080] In the above solution, by configuring the inner wall of the centrifugal chamber 11 as a smooth surface, the flow of the sewage is not hindered. Through the centrifugal action of the centrifugal filter screen 20, the contaminants in the sewage can be smoothly discharged. At the same time, the smooth surface avoids the accumulation of contaminants in dead corners, improving the disturbing effect of the disturbing member 22.

[0081] Specifically, the inner wall of the centrifugal chamber 11 is flush up and down, and the sewage flows more smoothly, avoiding energy loss.

[0082] Refer to Figure 7 , in some embodiments, the cover plate 60 includes a first part 63 and a second part 64.

[0084] In the above solution, by setting the first part 63 to be connected to the centrifugal filter screen 20 and the second part 64 to be connected to the base 10, the projection of the centrifugal filter screen 20 on the cover plate 60 is located on the first part 63, and the projection of the disturbing member 22 on the cover plate 60 is located on the second part 64. The disturbing member 22 disturbs the floating sewage more smoothly, thus avoiding interfering with the flow of the contaminants and making the discharge of the contaminants more smooth.

[0085] Refer to Figure 4 、 Figure 8, in some specific embodiments, the base 10 is further provided with a slag collection cavity 12 and a slag collection cavity inlet 13 communicating the centrifugal cavity 11 and the slag collection cavity 12. The slag collection cavity inlet 13 is configured as a slag discharge port. Among them, the slag collection cavity inlet 13 has a first edge 131 and a second edge 132. The second edge 132 and the first edge 131 are spaced apart and oppositely arranged in the circumferential direction of the centrifugal cavity 11. The first edge 131 is connected to the inner wall of the centrifugal cavity 11, and the second edge 132 is connected to the inner wall of the slag collection cavity 12. A tangential plane A passing through the first edge 131 and tangent to the inner wall of the centrifugal cavity 11 is made, and the second edge 132 is arranged on the side of the tangential plane A close to the centrifugal cavity 11.

[0086] In the related art, the cleaning device needs to filter various dirt, such as food residues, sediment or other foreign objects. Various dirt will be concentrated in the slag collection cavity, but the dirt is difficult to move, and the dirt discharge is not smooth.

[0087] In the embodiment of the present utility model, a centrifugal filter screen 20 is arranged in the centrifugal cavity 11, and the dirt is swung by centrifugal force. The dirt is guided into the slag collection cavity 12 through the slag collection cavity inlet 13. On the slag collection cavity inlet 13, the second edge 132 is arranged on the side of the tangential plane A close to the centrifugal cavity 11. The slag collection cavity inlet 13 has a guiding function. The slag collection cavity inlet 13 is larger, and the movement of the dirt is smoother, so that the dirt is discharged into the slag collection cavity 12 more smoothly, improving the smoothness of the dirt movement.

[0088] It should be noted that the tangential plane A is a virtual plane, a plane fictitiously set for the convenience of understanding, and the tangential plane A is tangent to the first edge 131.

[0089] Specifically, one end of the slag collection cavity inlet 13 communicates with the centrifugal cavity 11, and the other end communicates with the slag collection cavity 12. The first edge 131 is the edge where the slag collection cavity inlet 13 intersects with the centrifugal cavity 11, and the second edge 132 is the edge where the slag collection cavity inlet 13 intersects with the slag collection cavity 12. The tangential plane A is tangent to the first edge 131, and the second edge 132 is located inside the tangential plane A.

[0090] Refer to Figure 10 , in some embodiments, the slag collection cavity inlet 13 has a first wall surface 133 away from the first edge 131, and the second edge 132 is arranged on the first wall surface 133. The included angle between the first wall surface 133 and the tangential plane A is θ1, and 0≤θ1≤90°.

[0091] Among them, the slag collection cavity inlet 13 is a channel with a certain length, and the first wall surface 133 is the inner wall of the slag collection cavity inlet 13.

[0092] In the above solution, by setting θ1 within the range of 0 to 90°, the obstruction to the dirt is reduced, and the smoothness of the dirt movement is improved.

[0093] For example, θ1 is 45°; alternatively, θ1 is 0° and the first wall surface 133 is parallel to the tangential plane A; or θ1 is 80°.

[0094] Referring to Figure 10 , in some specific embodiments, the slag collecting cavity inlet 13 has a first wall surface 133 away from the first edge 131, the second edge 132 is provided on the first wall surface 133, and the first wall surface 133 is parallel to the tangential plane A.

[0095] In the above solution, by setting the first wall surface 133 parallel to the tangential plane A, the obstruction to the dirt is reduced, making the dirt pass through the slag collecting cavity inlet 13 more smoothly.

[0096] Referring to Figure 10 , in some embodiments, the slag collecting cavity inlet 13 has a second wall surface 134, and the second wall surface 134 is opposite and parallel to the first wall surface 133.

[0097] Among them, the slag collecting cavity inlet 13 is a channel with a certain length, the second wall surface 134 is the inner wall of the slag collecting cavity inlet 13 different from the first wall surface 133, and the second wall surface 134 and the first wall surface 133 are opposite surfaces.

[0098] In the above solution, by setting the second wall surface 134 parallel to the first wall surface 133, that is, the second wall surface 134 is parallel to the tangential plane A, the obstruction to the dirt is further reduced, making the dirt pass through the slag collecting cavity inlet 13 more smoothly.

[0099] In some specific embodiments, the slag collecting cavity inlet 13 has a second wall surface 134, the second wall surface 134 is opposite to the first wall surface 133, and the second wall surface 134 is configured as an arc-shaped wall, and the curvature direction of the arc-shaped wall faces the center of the centrifugal cavity 11.

[0100] In the above solution, by configuring the second wall surface 134 as an arc-shaped wall, the slag collecting cavity inlet 13 can make full use of the corners of the base 10, and connect the relatively far centrifugal cavity 11 and the slag collecting cavity 12 with a smaller size.

[0101] Referring to Figure 2 , in some embodiments, the base 10 is provided with a sewage collecting cavity 14, a centrifugal cavity inlet 15 and a sewage collecting cavity outlet 141. The centrifugal cavity inlet 15 connects the sewage collecting cavity 14 and the centrifugal cavity 11, and the sewage collecting cavity outlet 141 connects the sewage collecting cavity 14; the filtering device 100 includes a slag collecting and filtering member 30, the slag collecting and filtering member 30 is cylindrical, and is arranged in the sewage collecting cavity 14 and covers the sewage collecting cavity outlet 141.

[0102] Among them, the cylindrical slag collection and filtering member 30 covers the outlet 141 of the sewage collection cavity. The slag collection and filtering member 30 plays a filtering role. The centrifugal cavity inlet 15 communicates with the sewage collection cavity 14 and the centrifugal cavity 11. The cleaning liquid mixed with dirt first enters the sewage collection cavity 14, passes through the filtering of the slag collection and filtering member 30 and then enters the centrifugal cavity 11. The filtered cleaning liquid is discharged to the outlet 141 of the sewage collection cavity for subsequent recycling.

[0103] In the above solution, by arranging the slag collection and filtering member 30 at the outlet 141 of the sewage collection cavity, the cleaning liquid mixed with dirt first passes through the filtering of the slag collection and filtering member 30, thereby improving the cleanliness.

[0104] In some embodiments, the centrifugal cavity inlet 15 is arranged close to the bottom of the centrifugal cavity 11.

[0105] Among them, the centrifugal cavity inlet 15 is arranged on the side wall of the centrifugal cavity 11. The centrifugal cavity inlet 15 is close to the bottom of the centrifugal cavity 11. The cleaning liquid enters the centrifugal cavity 11 near the bottom of the centrifugal cavity 11.

[0106] In the above solution, by arranging the centrifugal cavity inlet 15 at a position close to the bottom of the centrifugal cavity 11, the cleaning liquid can disturb the sediment at the bottom of the centrifugal cavity 11, avoiding the accumulation of dirt at the bottom of the centrifugal cavity 11.

[0107] Specifically, the centrifugal cavity 11 is a cavity structure. The centrifugal cavity inlet 15 is opened at the bottom of the cavity structure. The cleaning liquid flowing in the centrifugal cavity 11 disturbs the dirt in the centrifugal cavity 11, avoiding the deposition of dirt at the bottom.

[0108] In some other embodiments, the centrifugal cavity inlet 15 is arranged at the bottom of the centrifugal cavity 11, and the cleaning liquid flows from bottom to top into the centrifugal cavity 11.

[0109] Refer to Figure 4 , in some embodiments, the bottom wall of the centrifugal cavity 11 is flush with the bottom wall of the sewage collection cavity 14, and the bottom wall surface of the centrifugal cavity inlet 15 is flush with the bottom wall of the centrifugal cavity 11.

[0110] Among them, the bottom wall of the centrifugal cavity 11 is flush with the bottom wall of the sewage collection cavity 14. The bottom wall surface of the centrifugal cavity inlet 15 is arranged at a lower position. The bottom wall surface of the centrifugal cavity inlet 15 is flush with the bottom wall of the centrifugal cavity 11. The cleaning liquid entering the centrifugal cavity 11 can disturb the dirt in contact with the bottom wall.

[0111] In the above solution, by setting the bottom wall surface of the centrifugal cavity inlet 15 to be flush with the bottom wall of the centrifugal cavity 11, the cleaning liquid disturbs the dirt at the bottom of the centrifugal cavity 11, further reducing the probability of dirt accumulation and improving the cleanliness.

[0112] Refer to Figure 4, in some embodiments, in the depth direction of the centrifugal chamber 11, the height of the centrifugal chamber inlet 15 is H1, the depth of the centrifugal chamber 11 is H2, and H1≥1 / 2H2.

[0113] Among them, the centrifugal chamber inlet 15 is opened on the centrifugal chamber 11. The centrifugal chamber inlet 15 has a certain height, and the cleaning liquid flows through the centrifugal chamber inlet 15 and enters the centrifugal chamber 11.

[0114] In the above solution, by setting H1≥1 / 2H2, the centrifugal chamber inlet 15 is opened larger, so that the flow of the cleaning liquid is smoother. At the same time, the cleaning liquid entering the centrifugal chamber 11 can affect a larger area, thereby improving the disturbance effect.

[0115] For example, H1 is equal to 1 / 2H2; or, H1 is equal to 5 / 8H2; or, H1 is equal to 2 / 3H2; or, H1 is equal to 7 / 8H2; or, H1 is equal to H2.

[0116] Refer to Figure 4 , in some embodiments, in the depth direction of the centrifugal chamber 11, the bottom wall surface of the slag collection chamber inlet 13 is located above the top wall surface of the centrifugal chamber inlet 15.

The bottom wall surface of the slag collection chamber inlet 13 is located above the top wall surface of the centrifugal chamber inlet 15, and the slag collection chamber inlet 13 is located above the centrifugal chamber inlet 15.

[0118] In the above solution, by setting the bottom wall surface of the slag collection chamber inlet 13 to be located above the top wall surface of the centrifugal chamber inlet 15, in the centrifugal chamber 11, the cleaning liquid flows from bottom to top, driving the dirt to flow upward, disturbing the dirt in the centrifugal chamber 11, and at the same time preventing the slag collection chamber inlet 13 from being blocked.

[0119] In some embodiments, the slag collection chamber inlet 13 is arranged near the top of the slag collection chamber 12.

[0120] Among them, the slag collection chamber inlet 13 is near the top of the slag collection chamber 12, and the dirt enters the slag collection chamber 12 from a higher position.

[0121] In the above solution, by arranging the slag collection chamber inlet 13 near the top of the slag collection chamber 12, the dirt enters the slag collection chamber 12 from a higher position, preventing the dirt in the slag collection chamber 12 from flowing back into the centrifugal chamber 11.

[0122] Refer to Figure 9 , in some embodiments, the base 10 is provided with a slag collection chamber outlet 17. The slag collection chamber outlet 17 communicates with the slag collection chamber 12. The filtering device 100 includes a slag collection filter screen 50.

[0124] In the above solution, by setting the slag collection filter screen 50 to filter dirt, the filtering effect is further improved, and multiple filtrations are carried out to further improve the utilization rate of the clean liquid.

[0125] In some specific embodiments, the base 10 is further provided with a slag discharge port, and the slag discharge port communicates with the slag collection chamber 12 to uniformly discharge dirt.

[0126] Refer to Figure 6 , in some embodiments, the filtering device 100 further includes a driving component 40. The driving component 40 is arranged on the base 10.

[0127] Among them, the driving component 40 is installed on the base 10. The rotating end 41 of the driving component 40 is connected to the centrifugal filter screen 20 and the slag collection filter screen 50 to drive the centrifugal filter screen 20 and the slag collection filter screen 50 to rotate.

[0128] In the above solution, by setting the driving component 40 connecting the centrifugal filter screen 20 and the slag collection filter screen 50, the driving component 40 can drive both the centrifugal filter screen 20 and the slag collection filter screen 50, thereby reducing the number of components and making the structure more compact.

[0129] Specifically, the driving component 40 includes: a driving motor 42, a first gear 43 and a second gear 44. The rotating end 41 of the driving motor 42 meshes with the first gear 43.
