Abstract
Description
Technical Field
[0001] This utility model relates to the field of water pump accessories technology, specifically a novel filter assembly for water pumps. Background Technology
[0002] Currently, most SP stainless steel pumps and 24V low-pressure stainless steel pumps on the market use built-in filters to prevent debris from entering the impeller and thus prevent pump blockage.
[0003] However, due to the large gap between the filter screen and the water pump shaft, debris can still enter the water pump, causing it to become clogged.
[0004] Therefore, we propose to design a new filter assembly for water pumps. Utility Model Content
[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.
[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:
[0007] A novel filter assembly for a water pump includes a first elastic retaining ring and a second elastic retaining ring. A stainless steel filter is disposed between the first and second elastic retaining rings. A water pump is disposed inside the first and second elastic retaining rings. Limiting rings are fixedly connected to the sides of the first and second elastic retaining rings that are close to each other. Mounting rings are fixedly connected to both ends of the stainless steel filter.
[0008] As a preferred embodiment of the novel filter assembly for a water pump described in this utility model, the outer wall of the stainless steel filter is provided with a cable hole, which facilitates the water pump cable to pass through the stainless steel filter and connect to an external power source.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] This invention utilizes the cooperation between a first elastic fixing ring, a second elastic fixing ring, and a stainless steel filter screen. The elasticity of the upper and lower elastic fixing rings secures the stainless steel filter screen to the outside of the water pump, effectively preventing debris from entering the water pump and causing blockage. Attached Figure Description

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.
[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0019] Please see Figure 1-3 This utility model provides a novel filter assembly for a water pump, including a first elastic fixing ring 1 and a second elastic fixing ring 2. A stainless steel filter 3 is provided between the first elastic fixing ring 1 and the second elastic fixing ring 2. A water pump 4 is provided inside the first elastic fixing ring 1 and the second elastic fixing ring 2. Limiting rings 6 are fixedly connected to the sides of the first elastic fixing ring 1 and the second elastic fixing ring 2 that are close to each other. Mounting rings 7 are fixedly connected to both ends of the stainless steel filter 3.
[0020] In this embodiment, a cable hole 5 is provided on the outer wall of the stainless steel filter screen 3, so that the cable of the water pump 4 can pass through the stainless steel filter screen 3 and be connected to an external power source.
[0021] In use, the first elastic retaining ring 1 and the second elastic retaining ring 2 are elastically fastened to the water pump 4, and the stainless steel filter screen 3 is fixed by the first elastic retaining ring 1 and the second elastic retaining ring 2.
[0022] During installation, first install the first elastic retaining ring 1, then install the stainless steel filter screen 3, pass the water pump 4 cable through the cable hole 5 on the stainless steel filter screen 3, and finally install the second elastic retaining ring 2.
[0023] Meanwhile, the stainless steel filter screen 3 can be either circular or conical.
[0024] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
