Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps and relates to a pump, in particular to a pump with a filtering function. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

[0003] The water pump consists of an impeller, a liquid inlet, a liquid outlet and a motor. After the motor is started, the impeller fixed on the output shaft of the motor rotates, and the liquid flowing in from the liquid inlet gradually approaches the impeller. The centrifugal force of the impeller's rotation can drive the liquid in the liquid inlet to flow to the liquid outlet.

[0004] However, if there are impurities in the liquid flowing from the liquid inlet to the liquid outlet and the impurities splash during the high-speed rotation of the impeller, it will cause multiple scratches on the inner wall of the water pump. Summary of the invention

[0007] In the above-mentioned pump with filtering function, the fixing member and the fixing part are provided as an integrally formed structure, and a step part is provided between the filter basket and the fixing part, so that there is a distance between the filter basket and the fixing part.

[0008] In the above-mentioned pump with filtering function, the diameter of the filter basket is arranged to decrease from top to bottom.

[0009] In the above-mentioned pump with filtering function, a fixing ring is arranged at the upper end of the filtering basket, and a supporting portion for the fixing ring to abut is fixedly arranged on the fixing member, and the supporting portion and the fixing member are integrally formed.

[0010] Compared with the prior art, the pump with filtering function has a filter basket detachably fixedly installed at the water inlet, through which water entering the water pump body is filtered to prevent impurities from entering the water pump body and damaging the impeller.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2 As shown, the pump with filtering function comprises a water pump body 1 and an impeller. The water pump body 1 is provided with a water inlet 2 for water inlet and a water outlet 3 for water outlet. The lower end of the water pump body 1 is provided with a driving motor 4 for driving the impeller to rotate. A fixing member 5 is fixedly provided on the water pump body 1 at a position relative to the water inlet 2. A filter basket 6 for filtering is provided in the fixing pipe. The filter holes 9 on the filter basket 6 will be clogged with impurities under long-term use, thereby resulting in a poor filtering effect. By removing the fixing member 5 from the fixing pipe, the filter holes 9 on the filter basket 6 will be clogged with impurities, thereby resulting in a poor filtering effect. The water pump body 1 can be disassembled to clean the filter holes 9 on the filter basket 6, thereby improving the filtering effect of the water pump body 1. When the filter basket 6 needs to be fixed, a fixing portion 7 for fixing and installing the filter basket 6 is fixedly provided on the inner wall of the fixing member 5. The fixing portion 7 is arranged in an inverted T-shaped structure. A water hole 8 for passing water is provided on the fixing portion 7. The filter basket 6 is provided with a filter hole 9 for filtering water. A fixing rod 10 is provided on the fixing portion 7. The filter basket 6 is provided with an opening for the fixing rod 10 to pass through.

[0016] To further elaborate, the fixing member 5 and the fixing portion 7 are integrally formed, and a step portion 11 is provided between the filter basket 6 and the fixing portion 7 so that there is a distance between the filter basket 6 and the fixing portion 7 .

[0017] To be more specific, water enters the water pump body 1 from the water inlet 2 of the water pump body 1 , passes through the filter basket 6 at the water inlet 2 , is filtered by the filter basket 6 , and then enters the interior of the water pump body 1 through the water hole 8 on the fixing part 7 .

[0018] To be more specific, the diameter of the filter basket 6 is arranged to decrease from top to bottom.

[0019] In further detail, a fixing ring 12 is disposed at the upper end of the filter basket 6 , and a supporting portion 13 for the fixing ring 12 to abut is fixedly disposed on the fixing member 5 , and the supporting portion 13 and the fixing member 5 are integrally formed.

[0020] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0021] Although the terms such as water pump body 1, water inlet 2, water outlet 3, drive motor 4, fixing member 5, filter basket 6, fixing part 7, water hole 8, filter hole 9, fixing rod 10, step part 11, fixing ring 12, and abutment part 13 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
