In this embodiment, the reinforcing ribs 34 divide the strainer portion 31 into a first filtering area and a second filtering area, that is, the ability of each filtering area to resist plastic deformation is improved by increasing the support on the strainer portion 31 and reducing the force-bearing area of the single filtering area, so that the ability of the strainer portion 31 to resist plastic deformation can be further improved, the installation firmness of the filtering component 3 can be further improved, and the service lives of the filtering component 3 and the submersible pump can be prolonged.

On the basis of any of the above embodiments, the shape of the overflowing hole 311 is not particularly required, and it may be a strip-shaped hole, a rectangular hole, a circular hole, or other various shapes that can allow the fluid to pass through, but in a preferred embodiment, the overflowing hole 311 is selected as a circular hole that can only ensure the overflowing amount of the fluid and can effectively block the impurities, and it is proved by a lot of experiments that if the diameter of the overflowing hole 311 is smaller than 1mm, the fluid will not pass through the strainer portion 31 of the filtering component 3, and the submersible pump will not be normally used; however, if the diameter of the overflowing hole 311 is greater than 5mm, the blocking effect of the filter member 3 on the foreign objects can be reduced, so in order to ensure the normal use of the submersible pump and the blocking effect of the filter member 3 on the foreign objects, the diameter of the overflowing hole 311 is preferably 1mm to 5 mm.

It should be noted that, on the basis of any of the above embodiments, the two filter screen portions 31 of the two filter elements 3 may be rotatably connected by any element or structure, such as a hinge, a pin or a bearing, which can be selected by the person skilled in the art as needed, and in this embodiment, the two filter screen portions 31 are preferably rotatably connected by a hinge 312 which is cheap, has a large rotation angle and has high connection strength.

In any of the above embodiments, the filter element 3 further includes a locking member 6 provided at the other end of the two ends of the filter screen part 31 not connected to the first fixing part 32 and the second fixing part 33 and capable of detachably fixing the two filter elements 3 to the cylinder 11. Adopt this kind of mode can be more convenient firm fix filtering component 3 on the barrel 11 of the pump body 1, also more convenient filtering component 3 dismouting simultaneously, wherein, locking component 6 is preferably firm in connection and the hasp structure that can dismantle fast, it is including establishing public hasp 61 in one of two filter screen portions 31, and establish on another of two filter screen portions 31 and can with public hasp 61 complex female hasp 62, can further improve filtering component 3's dismouting speed from this, reduce filtering component 3's dismouting time, and then more closely reduce the maintenance degree of difficulty of immersible pump.

In any of the above embodiments, the shape and structure of the filter screen portion 31 are not particularly limited, and it is only required to cover the liquid inlet 111 of the cylinder 11 and block all or part of impurities from entering the pump body 1, and a person skilled in the art can select the shape and structure according to needs. Meanwhile, the structure of the liquid inlet of the barrel in the submersible pump is fragile, and stones and the like carried in the fluid are extremely easy to crash the submersible pump, so that a distance is required to be arranged between the filter screen part 31 and the barrel 11 for buffering, and the structure of the liquid inlet of the barrel is prevented from being damaged by collision. Experiments prove that when the distance between the filter screen part 31 and the cylinder body 11 is less than 5mm, the purpose of buffering cannot be achieved; when the distance between the screen part 31 and the cylinder 11 is greater than 10mm, although the buffering purpose can be achieved, the space occupied by the filtering component 3 is increased, and the normal use of the submersible pump is seriously affected, so the distance between the screen part 31 and the cylinder 11 is preferably 5mm-10 mm.
