Description

Technical Field

[0001] The utility model relates to the technical field of filter element cleaning, in particular to a filter element with good filtering effect. Background Art

[0002] The filter element is an important component of a filtering device. Its function is to filter impurities, foreign matter and other substances in the fluid through multiple layers, so that the fluid filtered by the filter element is cleaner and purer. In order to ensure the filtering effect, the filter element that has been used for a long time needs to be cleaned and replaced regularly. The conventional filter element cleaning adopts the method of movable removal of the filter screen. The filter element structure designed in this way is complex, and it is necessary to design more anchoring structure points for the multi-layer filter element. At the same time, the outer cylinder wall of the conventional filter element is designed as an integral frame structure. Therefore, before removing the filter screen, the end covers at both ends of the filter element need to be disassembled one by one before the filter screen can be removed. The removal operation is cumbersome and there is a risk of damaging the filter screen. Therefore, those skilled in the art provide a filter element with good filtering effect to solve the problems raised in the above background technology. Utility Model Content

[0003] The purpose of the utility model is to provide a filter element with good filtering effect to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A filter element with good filtering effect comprises an upper shell and a lower shell. The upper shell and the lower shell are connected by a detachable structure. The upper end surface of the lower shell is evenly provided with four integrally formed clamping columns, and the lower end surface of the upper shell is equipped with a clamping groove. The upper shell and the lower shell are provided with a first positioning column and a second positioning column with ends extending to the interior. The upper shell and the lower shell are axially symmetrically provided with a first positioning groove and a second positioning groove for accommodating a first filter net and a second filter net. Filter holes are penetrated on the outer sides of the upper shell and the lower shell, and a water inlet is penetrated at the center of the first positioning column.

[0006] The above-mentioned filter element with good filtering effect has a simple structural design and low manufacturing cost. When in use, the first filter screen and the second filter screen are respectively inserted into the first positioning groove and the second positioning groove of the lower shell body, and the upper shell body and the lower shell body are assembled and installed through the card slot connection method. After the fluid is injected through the water inlet of the upper shell body, it is filtered through the first filter screen and the second filter screen layer by layer, and flows out from the filter holes on the outer wall of the shell body. When the filter element needs to be cleaned, the pry hole set on the surface of the lower shell body is used to pry the separation combination. At this time, the upper shell body is separated from the lower shell body, and the filter screen will automatically detach from the positioning groove, so that each component can be cleaned one by one. The disassembly process is quick and convenient, and there is no risk of damaging the filter screen.

[0007] As a further solution of the present invention: the edges of the first positioning groove and the second positioning groove close to the axial direction are both acute-angle structures.

[0008] As a further solution of the utility model: four rectangular prying holes are evenly arranged on the upper end surface of the lower shell along the circumferential direction, and the prying holes extend from the end surface to the bottom and are evenly spaced from the clamping columns.

[0009] As a further solution of the present invention: the upper shell and the lower shell are made of hard plastic.

[0010] As a further solution of the utility model: the first filter screen and the second filter screen are both made of formed stainless steel, and the mesh diameter of the first filter screen is larger than the mesh diameter of the second filter screen.

[0011] As a further solution of the utility model: filter cotton is arranged below the water inlet, and seven-in-one filter material is filled between the first filter screen and the second filter screen.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model has a simple design structure and low manufacturing cost. Through the structural design of the split upper shell and lower shell, the removal steps are few and the disassembly is convenient, so the filter element can be quickly disassembled and cleaned. At the same time, the positioning grooves arranged inside the upper shell and the lower shell can accurately insert and fix the filter screen without structural obstruction, which can avoid the damage of the filter screen caused by structural obstruction during the disassembly process and extend the service life.
