In some embodiments, when the guide tube 700 is provided with the reinforcing rib 720 on the upper side of the end relatively close to the outlet 120, the first side of the opening and closing baffle 810 can be fixed on the reinforcing rib 720, so that the first side of the opening and closing baffle 810 can be fixedly connected with the upper side of the end relatively close to the outlet 120 of the guide tube 700.

It should be noted that, in the present embodiment, when the driving element 310 runs and sewage flows toward the interior of the housing 100 through the inlet 110, the driving element 310 may drive the impeller 320 to rotate around the axial direction of the rotating shaft 312, so that the impeller 320 generates a centrifugal force, and the centrifugal force of the impeller 320 helps the sewage to overcome the elastic force or the gravity of the opening and closing baffle 810 to flush the opening and closing baffle 810, thereby achieving the rapid opening of the opening and closing baffle 810 to the inlet 110.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above examples only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.

Claims

1. A water body cleaner, comprising:

2. The water body cleaner as recited in claim 1, wherein an end of the housing away from the outlet is bent inward to form a flow guide tube, an opening of the flow guide tube at an end relatively close to the outlet forms the inlet, and the filtering unit is disposed at an end of the flow guide tube relatively close to the outlet.

3. The water body cleaner of claim 2, wherein the filter unit comprises:

4. The water body cleaner as recited in claim 3, wherein the opening and closing baffle is rotatably disposed at an end of the flow guide pipe relatively close to the outlet to open or close the inlet.

5. The water body cleaner of claim 2 wherein an auxiliary chamber is formed between the draft tube and the inner side wall of the housing for receiving large and heavy dirt from the sewage.

6. The water body cleaner as claimed in claim 1, wherein a water inlet is provided at a first end and/or periphery of the filtering mechanism, a water outlet is provided at a second end of the filtering mechanism, the sewage to be treated can flow into the housing through the inlet and towards the filtering mechanism, and the clean water obtained by filtering the sewage through the filtering mechanism can flow into the filtering mechanism through the water inlet and then sequentially flows out of the housing through the water outlet and the outlet; the first end of the filtering mechanism is the end of the filtering mechanism close to the inflow port, and the second end of the filtering mechanism is the end of the filtering mechanism close to the outflow port.

7. The water body cleaner of claim 6, wherein the filtering mechanism comprises a support cylinder and a filter element, the support cylinder is provided with the water inlet at a first end and/or on the periphery thereof, the support cylinder is provided with the water outlet at a second end thereof, and the filter element is arranged around the support cylinder in a region where the water inlet is arranged; the sewage to be treated can flow towards the filter element, and clear water obtained after the sewage is filtered by the filter element can flow into the supporting cylinder through the water inlet; the first end of the supporting cylinder is the end, close to the inflow opening, of the supporting cylinder, and the second end of the supporting cylinder is the end, close to the outflow opening, of the supporting cylinder.

8. The water body cleaner as recited in claim 7, wherein the water inlet is disposed at both the first end and the outer periphery of the support cylinder, the filter element is disposed around the outer periphery of the support cylinder, and the filter mechanism further comprises a sealing cap, the water inlet at the first end of the support cylinder is sealed by the sealing cap to block the unfiltered sewage from flowing into the support cylinder through the water inlet at the first end of the support cylinder.

9. The water body cleaner of claim 7 further comprising an impeller assembly disposed in the housing between the support cylinder and the outlet port, the impeller assembly being configured to draw the contaminated water into the housing through the inlet port and to cause the contaminated water to flow in a direction toward the filter element, and to draw the clean water in the support cylinder out of the support cylinder through the outlet port.

10. The water body cleaner of claim 9, wherein the impeller assembly includes a driving member disposed in the housing and having a rotating shaft, and an impeller disposed on the rotating shaft, the driving member being configured to drive the impeller to rotate about the rotating shaft in an axial direction via the rotating shaft, so that the impeller generates a centrifugal force for sucking the sewage and the clean water.
