[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0030] like Figure 1-5As shown, the utility model discloses a filter, which includes a filter element 50, a pump assembly and a filter housing. The filter housing includes an upper cover 20, a filter element housing 10 and a motor housing 30. The filter element housing 10 is provided with an inner cavity, a top opening and a bottom opening. The upper cover 20 is detachably connected to the top opening through a locking ring 21. The motor housing 30 is snap-connected to the filter element housing 10. The filter element 50 is placed in the inner cavity of the filter element housing 10, and the pump assembly is arranged on the motor housing 30.

[0031] A circle of limiting grooves 11 are provided on the outer edge of the top opening, and the edge of the upper cover 20 is placed in the limiting groove 11, thereby limiting the position of the upper cover 20, which is conducive to ensuring the stability of the position of the upper cover 20. A second sealing ring 12 is installed at the bottom of the limiting groove 11, and the edge of the upper cover 20 can press against the second sealing ring 12. The locking ring 21 is threadedly connected to the filter element housing 10, and a limiting edge 22 is provided on the locking ring 21 to limit the upper cover 20. After the upper cover 20 is placed in the limiting groove 11, the locking ring 21 is tightened to lock the upper and lower parts on the filter element housing 10, which is convenient and quick, and can also ensure the sealing between the two to avoid water leakage.

[0032] The upper end of the motor housing 30 is inserted into the bottom opening, and the motor housing 30 is provided with a step surface 31 that cooperates with the bottom opening to limit the insertion depth of the motor housing 30. A circle of convex edges 14 is also provided on the outer periphery of the bottom opening. The convex edges 14 abut the step surface 31, which can make the contact area between the filter housing 10 and the step surface 31 larger, which is conducive to ensuring the overall stability of the filter housing, and the step surface 31 is less likely to be damaged by pressure. A circle of mounting grooves 32 is provided at the upper end of the motor housing 30, and a first sealing ring 33 is provided in the mounting groove 32. The first sealing ring 33 is used to seal the gap between the motor housing 30 and the filter housing 10, thereby ensuring the sealing between the motor housing 30 and the filter housing 10.

[0033] In order to ensure the stable connection between the motor housing 30 and the filter element housing 10, a plurality of hooks 13 are arranged on the outer circumference of the bottom opening, and a slot 34 corresponding to the hook 13 is provided on the step surface 31 of the motor housing 30, and the hook 13 is engaged in the slot 34. After such arrangement, the assembly of the motor housing 30 and the filter element housing 10 does not require screw locking, which is very simple and convenient. In addition, a avoidance opening 35 corresponding to the hook 13 is provided at the lower end of the motor housing 30 (below the slot 34), and the avoidance opening 35 is connected to the slot 34. When the hook 13 is engaged with the slot 34, the hook portion of the hook 13 extends into the avoidance opening 35, but does not extend out of the avoidance opening 35, so as not to affect the placement stability of the filter housing.

[0034] The filter housing 10 is provided with a water inlet 15 and a water outlet 16, both of which are connected to the inner cavity of the filter housing 10. The motor housing 30 is provided with a water passage 36, one end opening of the water passage 36 (hereinafter referred to as the upper opening of the water passage 36) is connected to the inner cavity of the filter housing 10, and the other end opening of the water passage 36 (hereinafter referred to as the side opening of the water passage 36) is connected to the water outlet 16. A sealing gasket 37 is provided on the outer edge of the side opening of the water passage 36 to seal the gap between the side opening of the water passage 36 and the water outlet 16 to prevent sewage from directly infiltrating into the water outlet 16 without being filtered.

[0035] The pump assembly includes a motor and an impeller 41. The motor includes a stator 42 and a rotor 43. The rotor 43 is connected to the bottom of the impeller 41. A mounting cavity 38 and a connecting hole are provided at the bottom of the motor housing 30. The connecting hole connects the mounting cavity 38 and the water passage 36. The impeller 41 is placed in the water passage 36. The stator 42 is provided in the mounting cavity 38. The stator 42 is waterproof and insulated. The rotor 43 passes through the connecting hole and cooperates with the stator 42. After the stator 42 is powered on, the rotor 43 can be driven to rotate. The rotor 43 is rotatably connected to the connecting hole and sealed. The pump assembly arranged in this way is convenient for loading and unloading and maintenance. In order to prevent the impeller 41 from running out of the water passage 36, a water inlet cover 39 for limiting the impeller 41 is snap-connected to the upper opening of the water passage 36. A water permeable hole is provided on the water inlet cover 39. The water permeable hole connects the water passage 36 and the inner cavity of the filter housing 10.

[0036] The filter element 50 is arranged in the inner cavity of the filter element housing 10. The filter element 50 is tubular. The upper end of the filter element 50 is plugged into the upper cover 20, and the lower end of the filter element 50 is plugged into the water inlet cover 39. This arrangement can ensure the installation stability of the filter element 50. Sewage enters the inner cavity of the filter element housing 10 from the water inlet 15. After being filtered by the filter element 50, the filtered water flows from the inner cavity of the filter element 50 into the water passage 36, and then is pumped into the water outlet 16 by the pump assembly. A large amount of air will be introduced during filtration, so an exhaust valve 23 is detachably connected (such as threaded connection) on the upper cover 20. The exhaust valve 23 is placed above the inner cavity of the filter element 50. By setting the exhaust valve 23, the normal operation of the filter can be ensured.

[0037] The key point of the utility model is that by setting the pump assembly on the motor housing 30, the installation of the pump assembly is simpler and more convenient. After the pump assembly is installed on the motor housing 30, it is clamped with the filter housing 10 without screw locking, which is quick and convenient. The upper cover 20 can be detachably connected to the filter housing 10, which can facilitate the installation and replacement of the filter element 50.

[0038] The above description is only an embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
