Description

Technical Field

[0001] The utility model belongs to the technical field of water pumps and relates to an anti-clogging water pump. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of 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. It can also transport liquids, gas mixtures and liquids containing suspended solids.

[0003] General water pumps on the market will block the impeller during long-term operation due to the entanglement of some foreign objects or a large amount of mud and other debris blocking the water pump outlet or mixing into the pump, which will reduce the water output of the pump or even prevent it from discharging water, causing the pump's drainage volume to fail to meet the design requirements, wasting time and energy, or silt and entanglement are easy to stick to or entangle on the filter, causing the filter to become blocked, which also causes the sewage pump to not work normally or even burn the motor. Summary of the invention

[0004] The purpose of the utility model is to provide an anti-clogging water pump in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an anti-clogging water pump, comprising a water pump body, the water pump body is provided with a water inlet for water intake and a water outlet for water discharge, characterized in that a filter element for filtering is provided on the water pump body and at a position relative to the water inlet, a sewage outlet is provided on the water pump body and at a position relative to the filter element, a fixing part for the filter element to move up and down is provided at the water inlet, and a movable space for the filter element to move is provided in the fixing part, a water retaining part is provided at the upper end of the filter element, and the lower end of the filter element is opened. A filter hole for filtering water is provided, and a water hole for passing water is provided on the filter element. A control component connected with the filter element and controlling the filter element to move up and down is provided in the fixed part. The control component consists of a pull rod, a connecting rod, a pressure rod and a connecting spring. A protrusion is provided on the inner wall of the fixed part. The connecting rod passes through the protrusion and is connected to the pressure rod. One end of the pressure rod extends into the fixed part, and the other end of the pressure rod extends out of the fixed part and is connected to the pull rod. The connecting spring is sleeved on the connecting rod, and the filter element is moved up and down in the fixed part through the action of the reset spring.

[0006] In the above-mentioned anti-clogging water pump, a positioning protrusion for fixing is arranged on the outer end of the filter element, and a filter net is arranged on each of the filter holes.

[0007] In the above-mentioned anti-clogging water pump, a plug is provided on the water pump body at a position relative to the sewage outlet, and the plug is connected to the water pump body through a thread.

[0008] Compared with the prior art, the anti-clogging water pump is provided with a filter element on its water inlet part. When the filter holes on the filter element are blocked by impurities after long-term use of the water pump, the impurities on the filter element can be cleaned without disassembling the entire filter element, thereby achieving the purpose of improving the filtering effect of the filter element.

DETAILED DESCRIPTION

[0012] 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.

[0013] like Figure 1 , Figure 2As shown, the anti-clogging water pump comprises a water pump body 1, the water pump body 1 is provided with a water inlet 2 for water inlet and a water outlet 3 for water outlet, the water pump body 1 is provided with a filter element 4 for filtering at a position relative to the water inlet 2, the water pump body 1 is provided with a sewage outlet 5 at a position relative to the filter element 4, the water inlet 2 is provided with a fixing portion 6 for the filter element 4 to move up and down, and the fixing portion 6 has a movable space for the filter element 4 to move, the upper end of the filter element 4 is provided with a water retaining portion 7, the lower end of the filter element 4 is provided with a filter hole 8 for filtering water, and the filter element 4 is provided with a filter hole 8 for filtering water. A water hole 9 is provided for passing water. A control component connected to the filter element 4 and controlling the filter element 4 to move up and down is provided in the fixed part 6. The control component is composed of a pull rod 10, a connecting rod 11, a pressure rod 12 and a connecting spring 13. A protrusion 14 is provided on the inner wall of the fixed part 6. The connecting rod 11 passes through the protrusion 14 and is connected to the pressure rod 12. One end of the pressure rod 12 extends into the fixed part 6, and the other end of the pressure rod 12 extends out of the fixed part 6 and is connected to the pull rod 10. The connecting spring 13 is sleeved on the connecting rod 11, and the filter element 4 is moved up and down in the fixed part 6 through the action of the reset spring.

[0014] To elaborate further, during the normal operation of the water pump, liquid enters the pump body from the water inlet 2, and the liquid passes through the filter hole 8 on the filter element 4 to filter out impurities before entering the pump body.
