Description

Technical Field

[0001] This utility model relates to a water pump, specifically a water pump inlet. Background Technology

[0002] If the raw water contains stones, solid debris, or other impurities, it can damage the water pump.

The filter cylinder includes a cylindrical section and a bottom surface. The bottom surface is fixed to the bottom of the cylindrical section. A rubber ring is provided on the outer wall of the top of the cylindrical section. The rubber ring is placed on the support ring so that the cylindrical section is located inside the large section. The outer diameter of the cylindrical section is smaller than the minimum inner diameter of the large section. Both the cylindrical section and the bottom surface are filter screens.

[0006] Furthermore, the large section is narrow at both ends and wide in the middle, with the inner diameters of the two ends being the same as those of the connecting section and the water delivery section, respectively.

[0007] Furthermore, the bottom circumference of the large belly section is provided with multiple inclined blocks, and the bottom circumference is provided with multiple legs, which are supported on the inclined blocks.

[0008] Furthermore, a pull rod is provided at the center of the bottom surface, and a pull hole is provided at the top of the pull rod.

[0009] Furthermore, the cylindrical section is also equipped with a diaphragm, which has a straight tube for extending into the interior of the cylindrical section, and the maximum outer diameter of the diaphragm fits against the inner wall of the connecting section.

[0021] Example:

[0022] Figure 1 It is a cross-sectional schematic diagram of a water pump inlet, including an inlet pipe 1 and a filter cylinder 2 disposed inside the inlet pipe 1;

[0023] The water inlet pipe 1 includes a connecting section 12, a large section 11, and a water delivery section 13 connected in sequence. A support ring 15 is provided on the inner wall of the connecting section 12. The filter cylinder 2 includes a cylindrical section 21 and a bottom surface 22. The bottom surface 22 is fixed to the bottom of the cylindrical section 21. A rubber ring 26 is provided on the top outer wall of the cylindrical section 21. The rubber ring 26 is placed on the support ring 15 so that the cylindrical section 21 is located inside the large section 11. The outer diameter of the cylindrical section 21 is smaller than the minimum inner diameter of the large section 11. Both the cylindrical section 21 and the bottom surface 22 are filter screens.

[0024] This invention incorporates a filter cartridge to filter the raw water supplied to the water pump, accumulating impurities inside which are periodically removed and cleaned. Filtering out the impurities allows clean water to be supplied to the pump, preventing any impact on its lifespan.

[0025] The large section 11 is narrow at both ends and wide in the middle, with the two ends having the same inner diameter as the connecting section 12 and the water delivery section 13, respectively. The large diameter of the large section 11 allows the water from the filter cartridge to flow quickly into the water delivery section 13; a smaller diameter would affect the water flow rate.

[0026] The bottom circumference of the large section 11 is provided with multiple inclined blocks 14, and the circumference of the bottom surface 22 is provided with multiple support legs 23, which rest on the inclined blocks 14. The upper part of the filter cylinder is supported by a rubber ring 26 on the support ring 15, and the lower part is supported by the support legs and inclined blocks. The rubber ring 26 and the support ring 15 can also be connected by bolts to prevent the water flow from tilting the filter cylinder.

[0027] A pull rod 24 is provided at the center of the bottom surface 22, and a pull hole 25 is provided at the top of the pull rod 24. During cleaning, it can be pulled out by the pull hole 25 for cleaning.

[0028] The cylindrical section 21 is also equipped with an expansion mask 31. The expansion mask 31 has a straight tube 32 that extends into the interior of the cylindrical section 21. The maximum outer diameter of the expansion mask 31 fits against the inner wall of the connecting section 12. The expansion mask 31 guides the pumped raw water into the filter cartridge. The expansion mask 31 can be placed directly on top; even if there is leakage at the outer diameter fit, it will not be a problem, as the water will enter below. Under the action of water flow, the expansion mask 31 is impacted by the water flow. Because the outer edge is almost the same size as the inner wall of the filter cartridge and the straight tube extends into the filter cartridge, it will not be tilted even without bolt fixation.

[0029] Working principle:

[0030] Place the filter cylinder 2 into the water inlet pipe, so that the support leg 23 is placed on the inclined block 14, the rubber ring 26 is placed on the support ring 15 and bolted together, install the straight tube 32 of the expansion mask 31 into the filter cylinder 2, and fit the outer edge of the expansion mask 31 with the filter cylinder 2, and then connect the raw water pipe.

[0031] Raw water enters the filter cartridge 2 through the guide of the expansion mask 31. The residue is left inside the filter cartridge 2. The filtered raw water enters the water pump. When cleaning regularly: remove the raw water pipe, remove the expansion mask 31, remove the bolts, and remove the filter cartridge for cleaning.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
