Abstract

A pool cleaner including a first filter assembly and a second filter assembly is provided in the present disclosure. The first filter assembly includes a first housing defining a first chamber, where the first housing is provided with a first water inlet and a first water outlet; and a first filter device disposed in the first chamber configured to perform a first filtration to water from the first water inlet. The second filter assembly includes a second housing defining a second chamber provided with a second water inlet, the second water inlet is connected with the first water outlet; and a second filter device disposed in the second chamber configured to perform a second filtration to the first filtered water. The first housing is detachably connected with the second housing. The pool cleaner in the present disclosure has a good filtering effect and is easy to disassemble.

First claim

What is claimed is:

1. A pool cleaner, comprising:
a first filter assembly comprising:

a first filter device disposed in the first chamber configured to perform a first filtration to water from the first water inlet; and

a second filter assembly comprising:
a second housing defining a second chamber, where the second housing is provided with a second water inlet, and the second water inlet is connected with the first water outlet; and
a second filter device disposed in the second chamber configured to perform a second filtration to the first filtered water;

wherein the first housing is detachably connected with the second housing; and
wherein a bottom portion of the first housing is detachably connected with a side wall of the second housing via a first connector.

2. The pool cleaner according to claim 1 , wherein the first water outlet is positioned at the bottom portion of the first housing; and
the first connector comprises:
a first connection portion, protruding out of the side wall of the second housing, inserted through the first water outlet and extending into the first chamber, where the first connection portion is provided with a first through hole as the second water inlet; and

a first limit portion, disposed in the first chamber, surrounding an outside of the first connection portion and coupled with the first connection portion by a screw-thread fit.

3. The pool cleaner according to claim 1 , wherein at least an edge portion of the bottom portion of the first housing fits the side wall of the second housing along a circumferential direction of the first housing.

4. The pool cleaner according to claim 1 , wherein diameters of filter holes of the first filter device are greater than diameters of filter holes of the second filter device.

5. The pool cleaner according to claim 1 , further comprising:
a water pump, communicated with the second chamber; and
a third housing defining a third chamber configured to receive the water pump.

6. The pool cleaner according to claim 5 , wherein the water pump is provided with a water inlet pipe and a water outlet pipe; and
the water pump is communicated with the second chamber via the water inlet pipe, and the second filtered water flows into the water pump via the water inlet pipe and is drained out of the third chamber via the water outlet pipe.

7. The pool cleaner according to claim 6 , wherein an outlet is disposed on the third housing, and water flowing from the water outlet pipe flows out of the third chamber through the outlet.

8. The pool cleaner according to claim 7 , wherein at least one drain hole is disposed on the third housing, and the at least one drain hole is spaced from the outlet.

9. The pool cleaner according to claim 6 , wherein the second housing and the third housing are integrally formed, the second chamber and the third chamber are separated by a separator, a second through hole is disposed on the separator, and the water inlet pipe is inserted through the second through hole and extends into the second chamber.

10. The pool cleaner according to claim 9 , wherein the water inlet pipe ls detachably connected with the separator via a second connector.

11. The pool cleaner according to claim 10 , wherein the second connector comprises:
a second connection portion, disposed on the water inlet pipe and inserted through the second through hole and extending into the second chamber; and

a second limit portion, disposed in the second chamber, surrounding an outside of the second connection portion and coupled with the second connection portion by a screw-thread fit.

12. The pool cleaner according to claim 5 , wherein the first housing, the second housing and the third housing are arranged in a way to make:
a water flow direction from the first chamber to the second chamber is perpendicular to a water flow direction from the second chamber to the third chamber.

13. The pool cleaner according to claim 5 , further comprising a first end cap and a second end cap;
wherein the first end cap is coupled to an end of the second housing away from the third housing, and the second end cap is coupled to an end of the third housing away from of the second housing.

14. The pool cleaner according to claim 6 , wherein the second filter device comprises a filter element configured to perform the second filtration to the first filtered water;
the second chamber is partitioned to a first inner chamber and a second inner chamber by the filter element; and
the second water inlet is communicated with the first inner chamber, the second inner chamber is communicated with the water pump, and the first filtered water firstly flows into the first inner chamber and then flows into the second inner chamber through the filter element.

15. The pool cleaner according to claim 14 , wherein the filter element comprises a filter cartridge, a space between the filter cartridge and the second housing is the first inner chamber, and a space inside the filter cartridge is the second inner chamber; and
the water inlet pipe is at least partially positioned within the second inner chamber.

16. The pool cleaner according to claim 1 , wherein the first filter device comprises a filter basket, and the filter basket is provided with a plurality of filter holes and configured to perform the first filtration.

17. The pool cleaner according to claim 16 , wherein the first filter assembly further comprises a floating weir, and the floating weir comprises:
a hollow tubular structure; and
a flange, having an annular shape and a cross section in a downward curved arc shape, and an outer edge of the flange being connected with an upper end of the hollow tubular structure;
where the hollow tubular structure is disposed between the first chamber and the filter basket.

18. The pool cleaner according to claim 17 , wherein the first filter assembly further comprises a limit portion and an outer edge of the limit portion is connected with the first water inlet to limit the floating weir within the first chamber.

19. The pool cleaner according to claim 18 , wherein the first filter device further comprises a filter pad disposed within the filter basket; and
