Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump filter component. 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] Existing water pumps often cause blockages when pumping water, especially when there are a lot of debris in the water. This requires manual cleaning or reverse drainage cleaning, but both are time-consuming and labor-intensive. In addition, the debris from reverse drainage cleaning will accumulate again at the pumping pipe outlet, easily causing secondary blockage and making it inconvenient for efficient operation. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A water pump filter assembly, comprising: a body assembly and a filter assembly; wherein the body assembly comprises a pump body and a connecting pipe connected to the pump body; the filter assembly is arranged on the connecting pipe, and the filter assembly comprises a filter cartridge connected to the end of the connecting pipe, a filter head installed in the filter cartridge and docked with the connecting pipe, a water hole opened on the filter head, a water suction pipe connected to the other side of the filter cartridge, a drainage pipe connected to the bottom of the filter cartridge, a fixed frame fixed to the bottom of the drainage pipe, a baffle mounted on the fixed frame, a hinge shaft connected to the middle of the bottom surface of the baffle and two sets of sleeve rods hingedly connected between the hinge shaft and the fixed frame; the sleeve rod comprises a guide rod connected to the hinge shaft, a sleeve mounted on the end of the guide rod and a spring arranged in the sleeve.

[0007] In a preferred example, the utility model can be further configured as follows: a limiting plate located on the filter head side is fixed in the filter cartridge, and the limiting plate is a semicircular plate-shaped structure protruding inwards.

[0008] In a preferred example, the utility model can be further configured as follows: a pressure sensor is installed in the filter head.

[0009] In a preferred example, the utility model can be further configured as follows: the end of the filter head is in a cone shape, and the water hole is a vertically arranged opening.

[0010] In a preferred example, the utility model can be further configured as follows: an anti-reverse plate is provided at the end of the filter cartridge.

[0011] In a preferred example, the utility model can be further configured as follows: an anti-stacking block is fixed on the baffle.

[0012] The above technical solution of the utility model has the following beneficial technical effects:

[0013] The utility model uses a filtering component to allow the debris filtered out from the end of the filter head to accumulate in the filter cartridge and on the outside of the filter head. When the debris gradually increases, it will cause blockage. At this time, the pressure sensor detects that the pressure is too high, and then the pump body discharges water in reverse. Under the action of the anti-reverse plate, the water pressure increases to the drainage pipe, and the rear baffle moves downward, squeezing the triangular sleeve rod into an arrow shape pointing downward. At this time, the debris is discharged from the bottom of the drainage pipe to both sides. After the drainage, the pump body absorbs water again. At this time, the water source re-enters the water suction pipe and the drainage pipe. Under the action of the increased water pressure, the baffle is sucked up and cooperates with the sleeve rod to block the end of the drainage pipe again, and this process can be repeated. This scheme does not require manual operation, and the discharged debris will not accumulate at the entrance of the suction pipe, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0022] A water pump filter assembly provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0023] Combination Figure 1-3 As shown, the utility model provides a water pump filter assembly, comprising: a body assembly 100 and a filter assembly 200; wherein the body assembly 100 comprises a pump body 110 and a connecting pipe 120 connected to the pump body 110.

[0024] The filter assembly 200 is arranged on the connecting pipe 120, and the filter assembly 200 includes a filter cartridge 210 connected to the end of the connecting pipe 120, a filter head 220 installed in the filter cartridge 210 and docked with the connecting pipe 120, a water hole 230 opened on the filter head 220, a water suction pipe 240 connected to the other side of the filter cartridge 210, a drainage pipe 250 connected to the bottom of the filter cartridge 210, a fixing frame 260 fixed to the bottom of the drainage pipe 250, a baffle 270 sleeved on the fixing frame 260, a hinge shaft 280 connected to the middle of the bottom surface of the baffle 270 and two sets of sleeve rods 290 hingedly connected between the hinge shaft 280 and the fixing frame 260, the sleeve rod 290 includes a guide rod 291 connected to the hinge shaft 280, a sleeve 292 sleeved on the end of the guide rod 291 and a sleeve 292 arranged on the sleeve 292 The spring 293 inside can make the debris filtered out from the end of the filter head 220 accumulate in the filter cartridge 210 and on the outside of the filter head 220 through the filter assembly 200. When the debris gradually increases, it will cause blockage. At this time, the pressure sensor 221 detects that the pressure is too high, and then the pump body 110 reverses the water flow. Under the action of the anti-reverse plate 222, the water pressure increases to the drainage pipe 250, and then the baffle plate 270 moves downward, squeezing the triangular sleeve rod 290 into an arrow shape pointing downward. At this time, the debris is discharged from the bottom of the drainage pipe 250 to both sides. After the drainage, the pump body 110 absorbs water again. At this time, the water source re-enters from the water pumping pipe 240 and the drainage pipe 250. Under the action of the increased water pressure, the baffle plate 270 is sucked up and cooperates with the sleeve rod 290 to block the end of the drainage pipe 250 again. This can be repeated. This solution does not require manual operation, and the discharged debris will not accumulate at the entrance of the water pumping pipe 240, which is highly practical.

[0025] Specifically, a limiting plate 211 located on the side of the filter head 220 is fixed in the filter cartridge 210, and the limiting plate 211 is a semicircular plate-like structure protruding inward, which can reduce the volume of the upper part of the filter cartridge 210, thereby making the accumulation of debris more uniform, facilitating the accumulation of debris on the side of the water hole 230 at the same time, and facilitating the judgment of blockage.

[0026] Furthermore, a pressure sensor 221 is installed in the filter head 220 to detect the internal pressure and determine whether it is blocked. Of course, it is also possible to manually control the pump body 110 to work in reverse after observing that the water cannot be drained.

[0027] On the other hand, the end of the filter head 220 is in a cone shape, and the water hole 230 is a vertically arranged opening, which can prevent debris from accumulating at the water inlet.

[0028] It should be noted that an anti-reverse plate 222 is provided at the end of the filter cartridge 210 to prevent reverse flow and be used in conjunction with the removal of impurities. Of course, the water pressure can also be increased to compensate for the water pressure loss in the suction pipe 240 .

[0029] Furthermore, an anti-piling block 271 is fixed on the baffle 270 to prevent the accumulation of debris and facilitate its discharge.

[0030] The working principle and use process of the utility model are as follows: first, the filter cartridge 210 and the water suction pipe 240 are put into the water, and then the pump body 110 is used to pump water, and the debris therein is filtered out by the filter head 220. When the debris gradually increases, it will cause blockage. At this time, the pressure sensor 221 detects that the pressure is too high, and then the pump body 110 reverses the water flow. Under the action of the anti-reverse plate 222, the water pressure increases to the drainage pipe 250, and then the baffle plate 270 moves downward, squeezing the triangular sleeve rod 290 into an arrow shape facing downward. At this time, the debris is discharged from the bottom of the drainage pipe 250 to both sides. After the drainage, the pump body 110 absorbs water again. At this time, the water source re-enters from the water suction pipe 240 and the drainage pipe 250. Under the action of the increased water pressure, the baffle plate 270 is sucked up and cooperates with the sleeve rod 290 to block it again at the end of the drainage pipe 250, and this can be repeated. This scheme does not require manual operation, and the discharged debris will not accumulate at the entrance of the water suction pipe 240.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
