After the liquid to be treated passes through the filter element, its impurities are blocked. When cleaning is required, just take out the filter element, clean it, and reinstall it.

[0003] The filter element is the core unit of the filter and is a wearing part that needs to be cleaned or replaced regularly. Currently, the clamping structure of the filter element is mostly connected to the filter by bolts. This type of clamping connection has uneven force and can easily cause unstable sealing performance. It is not convenient to disassemble and install the filter element when replacing it. Utility Model Content

[0004] The utility model aims to provide a filter with a novel compression structure of a filter element, which changes the traditional bolt connection structure into a screw-in design, so that the filter element can be disassembled and assembled with the filter more conveniently.

[0006] As a preferred filter element with a new type of compression structure of the utility model, a combination plate is fixed on the inner wall of the slide groove, a limiting ball is fixed on the surface of the combination plate, the limiting ball is arranged in a semicircular structure, and a limiting hole is opened on the surface of the combination block.

[0007] As a preferred embodiment of the novel compression structure filter of the filter element of the utility model, the limiting ball is made of rubber material, and a mounting groove is provided on the surface of the combination block.

[0008] As a preferred filter element with a new type of compression structure of the utility model, the diameter of the installation rod is smaller than the positioning hole, the diameter of the limiting rod is the same as the inner diameter of the positioning hole, and the limiting rod, elastic metal sheet and installation rod are all arranged in an arc structure.

The filtered water will be discharged outward through the drain pipe. When disassembling and cleaning, first remove the top connecting shell from the surface of the water inlet pipe, and then rotate the filter element body so that the filter element body drives the combination block to slide on the inner wall of the slide groove. At this time, the combination block will contact the surface of the elastic metal sheet, causing the elastic metal sheet to deform through its own material and enter the positioning hole, so that the combination block can be separated from the surface of the limit rod and the installation rod. When the combination block is rotated to be located below the slot, the operator can quickly remove the filter element body and the filter housing by pulling the filter element body upwards, thereby making the installation and disassembly of the filter element body more convenient.

DETAILED DESCRIPTION

[0020] See also Figure 1-6 , a filter with a novel compression structure of a filter element, comprising a filter housing 1 and a filter element body 6, a bottom connecting shell 2 is fixed to the bottom of the filter housing 1, a top connecting shell 3 is threadedly connected to the top of the filter housing 1, a water inlet pipe 4 is connected to the top of the top connecting shell 3, a drain pipe 5 is connected to the bottom of the bottom connecting shell 2, the bottom of the filter element body 6 is closed, the filter element body 6 is located inside the filter housing 1, a connecting plate 7 is fixed to the inner wall of the bottom connecting shell 2, a supporting plate 8 is fixed to the surface of the connecting plate 7, a closing plate 9 is detachably connected to the top of the supporting plate 8, a plurality of assembly blocks 10 are fixed below the surface of the filter element body 6, a card slot 11 is provided on the surface of the closing plate 9, a slide slot 12 is provided on the surface of the supporting plate 8, the number of the card slot 11 and the slide slot 12 matches the number of the assembly block 10, a plurality of limiting rods 13 are fixed to the inner wall of the supporting plate 8, a mounting rod 14 is fixed to the surface of the limiting rod 13, an elastic metal sheet 15 is fixed to the surface of the mounting rod 14, and a positioning hole 16 is provided on the surface of the assembly block 10;

[0021] When the filter element body 6 is located inside the filter housing 1, the top connecting shell 3 connected by thread will tightly press the top of the filter element body 6 together with the water inlet pipe 4, so that the top of the filter element body 6 is not easy to move, and the bottom assembly block 10 of the filter element body 6 will be located inside the slide groove 12, and the limiting rod 13 will be located inside the positioning hole 16, and the elastic metal sheet 15 will pass through the assembly block 10 to limit the assembly block 10, and the unfiltered water will enter the filter element body 6 through the water inlet pipe 4 and be discharged by the filter material on the surface of the filter element body 6. The filtered water will be discharged outward through the drain pipe 5. When the filter element body 6 needs to be disassembled and cleaned First, remove the top connecting shell 3 from the surface of the water inlet pipe 4, and then rotate the filter element body 6 so that the filter element body 6 drives the assembly block 10 to slide on the inner wall of the slide groove 12. At this time, the assembly block 10 will contact the surface of the elastic metal sheet 15, so that the elastic metal sheet 15 deforms through its own material and enters the positioning hole 16, so that the assembly block 10 can be separated from the surface of the limit rod 13 and the installation rod 14. When the assembly block 10 is rotated to be located below the card slot 11, the operator can quickly remove the filter element body 6 and the filter housing 1 by pulling the filter element body 6 upwards, thereby making the installation and disassembly of the filter element body 6 more convenient.

[0022] Furthermore, a combination plate 17 is fixed to the inner wall of the slide groove 12, a limiting ball 18 is fixed to the surface of the combination plate 17, the limiting ball 18 is arranged in a semicircular structure, and a limiting hole 19 is provided on the surface of the combination block 10;

[0023] When the assembly block 10 rotates in the slide slot 12 until the limiting rod 13 is located in the positioning hole 16 , the limiting ball 18 can enter the limiting hole 19 , thereby improving the positioning effect of the assembly block 10 .

[0024] Furthermore, the limiting ball 18 is made of rubber, and a mounting groove 20 is provided on the surface of the assembly block 10;

[0025] The rubber limiting ball 18 ensures that it can deform and has greater friction, thereby improving the limiting effect on the combination block 10. The setting of the installation groove 20 ensures that when the limiting ball 18 contacts the surface of the combination block 10, the limiting ball 18 can deform on the surface of the installation groove 20.

[0026] Furthermore, the diameter of the mounting rod 14 is smaller than the positioning hole 16, the diameter of the limiting rod 13 is the same as the inner diameter of the positioning hole 16, and the limiting rod 13, the elastic metal sheet 15 and the mounting rod 14 are all arranged in an arc-shaped structure;

[0027] The arc-shaped structure allows the limiting rod 13 and the mounting rod 14 to be normally inserted into the positioning hole 16, and the setting of the diameter of the positioning hole 16 allows the mounting rod 14 to drive the elastic metal sheet 15 to pass through the positioning hole 16, so that the elastic metal sheet 15 has enough space to deform.

[0028] Furthermore, a plurality of rubber pads 21 are fixed on the surface of the combined plate 17;

[0029] The rubber pad 21 can increase the friction between itself and the contact surface of the assembly block 10 , so that after the assembly block 10 and the rubber pad 21 are in contact with each other, the assembly block 10 is not easy to drive the filter element body 6 to move.

[0030] Furthermore, a plurality of fastening screws 23 are threadedly penetrated on the surface of the closing plate 9, and a plurality of threaded holes 22 are opened on the surface of the supporting plate 8;

[0031] By rotating the fastening screw 23, it can be taken out from the closing plate 9 and the threaded hole 22, so that the closing plate 9 can be removed from the surface of the support plate 8, making it easier to inspect and install the internal components of the support plate 8.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
