Description

Technical Field

[0001] This utility model relates to a swimming pool water pump, and more particularly to a filter basket for the swimming pool water pump. Background Technology

[0002] Self-priming water pumps, such as the one with patent publication number CN 217107453 U that enhances self-priming capability, often have a filter basket installed inside the pump body. This allows the larger impurities in the water to be filtered to be removed by the filter basket before entering the impeller. However, in current pumps of this type, the pores of the filter basket are relatively large (due to limitations in manufacturing processes and conditions such as injection molding, the pores cannot be made very small). As a result, small impurities in the water still enter the pump body and come into contact with the impeller. Some of these larger particles (such as fine sand smaller than the pores of the filter basket) can also damage the impeller. Over time, this can damage the impeller and reduce its lifespan. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a water pump filter basket with a mesh bag that has a more reasonable structure and can improve the service life of the water blades.

[0004] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0005] A water pump filter basket with a mesh bag includes a filter basket and a mesh bag structure, wherein:

[0006] The filter basket is U-shaped and includes a basket body with filter holes densely distributed on its peripheral walls, a base, and a frame; a water inlet is provided on the side wall of the basket body;

[0007] The mesh bag structure is vertically and detachably installed into the filter basket. It includes a U-shaped mesh bag, a fixed inner ring, and a fixed outer ring, which are respectively clamped on the inner and outer sides of the mesh bag opening. The fixed inner ring and the fixed outer ring are respectively provided with an inner edge and an outer edge of the bag wall on the side facing the water inlet of the basket. The outer edge of the bag wall, the mesh bag, and the inner edge of the bag wall are respectively provided with an outer edge water inlet, a mesh bag water inlet, and an inner edge water inlet at the position directly opposite the water inlet. The mesh bag is a woven mesh or a woven bag, and its pores are smaller than the filter holes of the filter basket.

[0008] In the improved design of the water pump filter basket with mesh bag, the inner edge water inlet of the fixed inner ring and the outer edge water inlet of the fixed outer ring are integrally formed during injection molding; the mesh bag water inlet is cut out after the mesh bag is clamped and fixed by the inner edge and outer edge of the bag wall.

[0009] In the improved design of the water pump filter basket with mesh bag described above, the mesh bag, the inner fixing ring and the outer fixing ring are fixed by ultrasonic welding.

[0010] In the improved design of the water pump filter basket with mesh bag described above, an installation and positioning structure is provided between the fixed outer ring and the filter basket.

[0011] In the improved design of the water pump filter basket with mesh bag described above, the installation and positioning structure includes a notch groove on the fixed outer ring and a positioning boss on the filter basket.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: A mesh bag structure, comprising a U-shaped mesh bag, a fixed inner ring, and a fixed outer ring, is detachably placed in the filter basket. The fixed inner ring and the fixed outer ring are respectively provided with an inner clamping edge and an outer clamping edge of the bag wall for clamping the mesh bag in the direction facing the water inlet of the basket. Furthermore, the outer clamping edge of the bag wall, the mesh bag, and the inner clamping edge of the bag wall are respectively provided with an outer clamping edge water inlet, a mesh bag water inlet, and an inner clamping edge water inlet at positions facing the water inlet of the basket. When the filter basket is fitted with the mesh bag structure... After the structure is completed, the mesh bag is always attached to the water inlet of the filter basket. This prevents water at the filter basket inlet from washing the mesh bag open and directly entering the pump body. This ensures that the water to be filtered is filtered through the mesh bag, flows into the pump body through the filter holes of the filter basket, and is then pumped out by the pump. Since the pores of the mesh bag are smaller than the filter holes of the filter basket, the filtration effect of the mesh bag is better, which greatly reduces the impact of fine sand and other impurities in the water on the water blades. Therefore, the structure of this utility model is more reasonable and can improve the service life of the water blades.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: Attached Figure Description

[0014] Figure 1 This is a perspective view of an embodiment of the present utility model;

[0015] Figure 2 This is an assembly diagram of an embodiment of the present utility model. Detailed Implementation

[0016] This utility model is a water pump filter basket with a mesh bag, as shown in 1 and 2, including a filter basket 1 and a mesh bag structure, wherein:

[0017] The filter basket 1 is U-shaped and includes a basket body 11 with filter holes 111 densely distributed on its peripheral walls, a base 12, and a frame 13; an inlet 112 is provided on the side wall of the basket body 11.

[0018] The mesh bag structure is vertically and detachably installed into the filter basket 1. It includes a U-shaped mesh bag 21, a fixing inner ring 22, and a fixing outer ring 23. The fixing inner ring 22 and the fixing outer ring 23 are respectively clamped on the inner and outer sides of the opening of the mesh bag 21. The fixing inner ring 22 and the fixing outer ring 23 are respectively provided with an inner edge 221 and an outer edge 231 on the side facing the water inlet 112 of the basket body 11. The outer edge 231 and the mesh bag 21 are respectively provided with an inner edge 221 and an outer edge 231. The inner edge 221 of the bag wall is provided with an outer edge water inlet 2311, a mesh bag water inlet 211 and an inner edge water inlet 2211 respectively on the water inlet 112. This ensures that the mesh bag 21 is always attached to the water inlet, while preventing the water at the water inlet from washing the mesh bag open and directly entering the pump body. This ensures that the water to be filtered can be filtered by the mesh bag before being pumped out. The mesh bag 21 is a woven mesh or woven bag, and its pores are smaller than the filter holes 111 of the filter basket 1.

[0019] As can be seen from the above, since a mesh bag structure is detachably placed in the filter basket, which includes a U-shaped mesh bag 21, a fixed inner ring 22, and a fixed outer ring 23, the fixed inner ring 22 and the fixed outer ring 23 are respectively provided with an inner clamping edge 221 and an outer clamping edge 231 of the bag wall to clamp the mesh bag 21 in the direction of the water inlet 112 of the basket body 11. Moreover, the outer clamping edge 231, the mesh bag 21, and the inner clamping edge 221 are respectively provided with an outer clamping edge water inlet 2311, a mesh bag water inlet 211, and an inner clamping edge water inlet 2211 at the position directly opposite the water inlet 112 of the basket body 11. When the filter basket is fitted with the mesh bag structure, the mesh bag 21 always adheres to the water inlet 112 of the filter basket 1. This prevents water at the filter basket inlet from being flushed open and directly entering the pump body, ensuring that the water to be filtered is filtered through the mesh bag and flows into the pump body through the filter holes 111 of the filter basket 1, and then pumped out by the pump. Since the pores of the mesh bag 21 are smaller than the filter holes 111 of the filter basket 1, the filtration effect of the mesh bag is better, which greatly reduces the impact of fine sand and other impurities in the water on the water blades. Therefore, the structure of this utility model is more reasonable and can improve the service life of the water blades.

[0020] Mesh bags, usually made of fine nylon mesh, have mesh openings whose size can be determined as needed during weaving.

[0021] In this embodiment, the inner edge inlet 2211 of the inner fixing ring 22 and the outer edge inlet 2311 of the outer fixing ring 23 are integrally formed during injection molding. Since the mesh bag is a very soft material, the mesh bag inlet 211 of the mesh bag 21 is cut out after the mesh bag is clamped and fixed by the inner edge 221 and the outer edge 231 of the bag wall. This ensures that the mesh bag inlet 211 is perfectly aligned with the outer edge inlet 2311 and the inner edge inlet 2211, and also improves the production efficiency of the mesh bag structure. Preferably, the inner fixing ring 22 and the outer fixing ring 23 are ultrasonically welded at the ring opening and around their inlets to simultaneously fix the mesh bag.

[0022] Preferably, an installation positioning structure 3 is provided between the fixed outer ring 23 and the filter basket 1 to ensure that the water inlet of the mesh bag structure 2 automatically aligns with the water inlet of the filter basket each time it is inserted into the filter basket. In this embodiment, the installation positioning structure 3 includes a notch 31 on the fixed outer ring 23 and a positioning boss 32 on the filter basket. Of course, the positioning boss can also be provided on the fixed outer ring, and the notch 32 can be provided on the filter basket.

[0023] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
