DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figures 1 to 4 , a water pump filtering device, comprising: a filter tube 2, one end of the filter tube 2 is connected to the water inlet of the water pump 1, and the other end of the filter tube 2 is connected to the water supply source;

[0033] A filter assembly 3, the filter assembly 3 is arranged in the filter tube 2, and is used to filter and remove impurities from the water entering the water pump 1;

[0034] The filter assembly 3 comprises: a mounting frame, a filter plate and a first spring 7;

[0035] The mounting frame is connected to the inner wall of the filter tube 2, and the mounting frame is a telescopic structure;

[0036] The first spring 7 is arranged at the telescopic space of the mounting frame and is connected to the mounting frame;

[0037] The filter plate is embedded in the mounting frame, and the setting direction of the filter plate is perpendicular to the water flow direction. When the water flow impacts the filter plate, the first spring 7 undergoes elastic deformation to offset the impact force of the water flow on the filter plate.

[0038] Among them, the main invention point of the present application is that by setting the filter component as an elastic structure, the filter plate can undergo elastic deformation when it is subjected to the impact force of the water flow, and the elastic force can be used to offset the impact force on the filter plate, thereby avoiding deformation of the filter plate when the water flow pressure is too high, thereby affecting the filtering effect.

[0039] In addition, a sewage pipe for sewage discharge is arranged at the bottom of the filter tube.

[0040] In some embodiments, the mounting frame includes: a first annular circular plate 4, a second annular circular plate 5 and a first connecting rod 6;

[0041] There is a gap between the first annular circular plate 4 and the second annular circular plate 5;

[0042] One end of the first connecting rod 6 passes through the first annular circular plate 4, and the other end of the first connecting rod 6 is connected to the second annular circular plate 5;

[0043] The filter plate is connected to the inner wall of the first annular circular plate 4, and the first spring 7 is sleeved on the first connecting rod 6 between the first annular circular plate 4 and the second annular circular plate 5;

[0044] A plurality of first connecting rods 6 are arranged along the circumferential direction of the first annular circular plate 4 , and each of the first connecting rods 6 is sleeved with the first spring 7 .

[0045] The mounting frame is used to support the filter plate and, when the filter plate is impacted by water flow, the first spring is elastically deformed to offset the force of the water flow on the filter plate, thereby avoiding deformation of the filter plate.

[0046] In some embodiments, the filter plate comprises: a sleeve 8 and a filter bowl 9;

[0047] The sleeve 8 is in a T-shaped structure, the filter bowl 9 is in a bowl-shaped structure, and a plurality of filter holes are provided at the bottom of the filter bowl 9;

[0048] The sleeve 8 is sleeved in the first annular circular plate 4, and the inner wall of the first annular circular plate 4 is provided with convex edges adapted to the edge pressure of the sleeve 8;

[0049] An annular plate 10 is disposed at the bottom of the sleeve 8, and a plurality of second connecting rods 11 are disposed on the annular plate 10 along the axial direction;

[0050] The filter bowl 9 is sleeved in the sleeve 8, and the second connecting rod 11 is disposed through the sleeve 8;

[0051] A second spring 12 is sleeved on the second connecting rod 11 between the filter bowl 9 and the annular plate 10 .

[0052] Among them, the function of the sleeve is to install the filter bowl, and the function of the second spring is to perform a second buffer under the buffering action of the first spring when the filter bowl is impacted by the water flow, thereby utilizing double shock absorption to protect the filter bowl from deformation to the greatest extent.

[0053] Specifically, when the filter plate is impacted by water flow, the water flow exerts a force on the filter plate, the filter plate transfers the force to the sleeve, and the sleeve transfers the force to the mounting frame. In the process of force transmission, since the first spring and the second spring are compressed, part of the force is offset by the first spring, and the other part of the force is offset by the second spring. In this way, the problem of deformation of the filter bowl when the water flow impacts the filter bowl is avoided.

[0054] In some embodiments, the bottom of the filter bowl 9 is a movable structure, and a plurality of blades 13 are obliquely arranged at the bottom of the filter bowl 9, and the blades 13 are arranged along the axial direction of the bottom center of the filter bowl 9;

[0055] When the water flow impacts the blades 13 at the bottom of the filter bowl 9, the bottom of the filter bowl 9 rotates.

[0056] Among them, the bottom of the filter bowl is set as a rotating structure, and blades are set at the bottom of the filter bowl, so that the bottom of the filter bowl can form an impeller structure. When the water flow hits the bottom of the filter bowl, the adhesion force of impurities on the filter bowl can be reduced, thereby reducing the problem of impurities clogging the filter holes in a short time.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
