Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. As shown in fig. 1, 2, 4 and 5, the present application provides a filter cartridge comprising: inner layer section of thick bamboo 1, outer layer section of thick bamboo 2 and filter screen 3.

The inner layer cylinder 1 is provided with at least one inner layer filtering port 11 on the side surface; the outer layer cylinder 2 is detachably arranged on the outer side surface of the inner layer cylinder 1, and at least one outer layer filtering port 21 is arranged on the side surface of the outer layer cylinder 2; and the filter screen 3 is embedded between the inner layer cylinder 1 and the outer layer cylinder 2.

It can be understood that the filter element is impacted by water input at the inlet of the filter device, and the filter screen of the filter element is easy to damage. And the filter screen 3 is difficult to fix if the filter screen is separately fixed on the filter element. So in this application an inlayer section of thick bamboo 1 and an outer section of thick bamboo 2 have realized filter screen 3's fixed through three layer construction when playing the protection to the filter screen with filter screen 3 centre gripping. Because the three-layer structure is formed among the inner layer cylinder 1, the outer layer cylinder 2 and the filter screen 3, the three-layer structure is very troublesome for replacing the filter screen. This application establishes outer shell 2 and filter screen 3 into detachable structure to be fixed in filter urceolus 6 with inlayer section of thick bamboo 1 through apron subassembly 4, make when changing filter screen 3, only need use apron subassembly 4 and filter urceolus 6 to break away from the joint state and take out whole filter core again. Then, the inner layer cylinder 1 is not required to be removed, and only the fixing screw 5 is required to be removed to separate the outer layer cylinder 2 so as to replace the filter screen 3.

Specifically, as shown in fig. 7 and 8, the outer layer cylinder 2 and the screen 3 are fixed to the inner layer cylinder 1 by fixing screws 5.

In some embodiments, the filter cartridge further comprises: and the cover plate component 4 is arranged at two ends of the inner layer barrel 1, and the inner layer barrel 1 is connected with the filter outer barrel 6 in a clamping manner through the cover plate component 4.

Specifically, as shown in fig. 3, the cover plate assembly 4 includes: a bottom plate 41 and an upper cover plate 42;

a bottom plate 41 connected to the bottom of the inner tube 1; and the upper cover plate 42 is connected with the top of the inner barrel 1, an upper cover plate opening 421 is arranged on the outer side surface of the upper cover plate 42, and the upper cover plate opening 421 is used for being circumferentially fixed with the filter outer barrel 6.

It is worth mentioning that at least one leaf spring 43 is provided on the upper cover plate 42, and the inner cartridge 1 is axially fixed to the filter outer cartridge 6 by the leaf spring 43.

It is understood that, as shown in fig. 6, the plate spring 43 has a band shape, both ends of the plate spring 43 are fixed to the upper cover plate 42, and the middle portion is protruded upward to be connected to the colander outer tub 6. The end of the plate spring 43 is designed to be saw-toothed, and the teeth of the saw-toothed are fixed to the upper cover plate 42 by pins. The filter insert is thereby fixed both circumferentially and axially to the filter outer cylinder 6. One end of the pin penetrates through the upper cover plate 42 and is fixed with other parts below the upper cover plate 42, the other end of the pin is provided with a nut, and the nut is abutted against two saw teeth of the plate spring 43 so as to realize the connection and fixation of the plate spring 43 and the upper cover plate 42,

Preferably, as shown in fig. 9, the bottom plate 41 includes: an inner circular portion 411 having a shape and a position corresponding to the bottom of the inner layer cylinder 1; an outer circular arc portion 412 concentric with the inner circular arc portion 411, wherein the outer circular arc portion 412 is used for being clamped with the filter outer cylinder 6.

It is worth mentioning that the bottom plate 41 includes: the outer side surface of the inner layer cylinder 1 is provided with a water input inner opening 12; the outer side surface of the outer layer cylinder 2 is provided with a water input outer port 22, and the water input outer port 22 corresponds to the water input inner port 12 in position.

Preferably, a bent part 121 is arranged on the end surface of the water input inner port 12 of the inner layer cylinder 1, and the bent part 121 can be clamped with the end surface of the water input outer port 22.

It will be appreciated that the strainer outer housing 6 is provided with water inlets at positions corresponding to the water inlet inner and outer ports 12, 22.

On the other hand, the filter cartridge of the present application is applied to a filter device, and the filter cartridge is provided in the filter outer cylinder 6.

The application principle of this application filter equipment is: liquid to be filtered enters the water inlet 12 through the water inlet of the filter outer cylinder 6, impurities are filtered by the inner-layer filtering opening 11 through the filter screen 3, and finally the liquid flows out of the outer-layer filtering opening 21.

When the filter screen 3 needs to be replaced, the cover on the top of the filter outer cylinder 6 is opened, the filter element is rotated to enable the bottom plate 41 and the upper cover plate 42 to be separated from the filter outer cylinder 6 in a clamping state, and then the filter element is taken out and taken out of the fixing screw 5 to replace the filter screen 3.

In summary, the applicant of the embodiment of the present invention finds that the real reason for the damage of the filter element is because the filter screen is easily broken during the use and cleaning processes, and the maintenance cost is increased because the filter screen has to be replaced frequently by the operator. Consequently, this application adopts inside and outside bilayer structure to when fixed filter screen, can be through demolising outer shell section of thick bamboo with the quick replacement filter screen. The filter element in the embodiment of the invention has a three-layer structure, the inner layer of the filter element is fixedly connected with the outer cylinder of the filter, the filter element does not need to be completely removed during replacement, only the filter screen needs to be replaced, the service life of the filter element is prolonged, and the cost is saved.
