[0002] Filter element is a professional term for filtering and purifying functions. It is a simple device for purifying the resources of raw fluids and separating resources. It mainly includes gas-liquid separation, solid-liquid separation, exhaust dust filtration, and environmental protection. Now the filter element is mainly divided by material: stainless steel filter element, copper filter element, titanium filter element, Hastelloy, plastic filter element and other materials; it is mainly used in oil filtration, air filtration, water filtration, etc., as well as machinery, electronics, petroleum, chemical industry, transportation, and other fields.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] At present, the filter element is installed inside the equipment together with the filter cartridge. When the filter element needs to be removed and replaced separately, the filter cartridge cover needs to be opened. Usually, the cover is opened and placed aside. The cover is easily stained with dust and impurities during the placement process. When the cover is closed again, the dust and impurities will enter the filter cartridge. Secondly, when the filter element is installed inside the filter cartridge, it is mounted on the vertical rod inside the filter cartridge. The filter element is prone to shaking and is unstable to use.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0030] See attached Figure 1-5 A filter element that is easy to disassemble and replace includes a base 1. A plurality of mounting grooves 101 are opened on the top of the base 1. A filter cartridge 2 is detachably mounted inside the mounting groove 101. A detachably mounted filter element 3 is arranged inside the filter cartridge 2. A sealing cover 4 is elastically connected to the top of the filter cartridge 2. The sealing cover 4 covers the filter cartridge 2. A fixing component is arranged on the bottom wall of the sealing cover 4. The fixing component fixes the upper part of the filter element 3.

[0031] In this embodiment, an extension column 5 is fixedly connected to the upper part of one side wall of the filter cartridge 2, one end of the extension column 5 is fixedly connected to a limiting plate 6, an elastic rope 7 is connected to the upper wall of the extension column 5, and the top of the elastic rope 7 is connected to the bottom wall of the sealing cover 4.

[0032] It should be noted that after the sealing cover 4 is opened, it is elastically connected to the elastic rope 7, so that the sealing cover 4 always maintains the connection with the filter cartridge 2, which greatly facilitates the operation of the user.

[0033] In this embodiment, a sealing ring 8 is fixedly connected to the bottom wall of the sealing cover 4, and the fixing assembly includes a plurality of telescopic seats 9, and the plurality of telescopic seats 9 are evenly distributed on the inner wall of the sealing ring 8. A spring 10 is fixedly wound around the outside of the telescopic end of the telescopic seat 9, and a rubber plate 11 is connected to the telescopic end of the telescopic seat 9. The inner wall of the rubber plate 11 fits with the outer wall of the filter element 3.

[0034] It should be noted that the sealing cover 4 is covered on the top of the filter cartridge 2, and the sealing ring 8 is inserted into the interior of the filter cartridge 2. When the sealing ring 8 is inserted as a whole, the filter element 3 squeezes the rubber plates 11 on both sides. The rubber plates 11 are elastically pressed by the telescopic seat 9 and the spring 10, so that the rubber plates 11 are firmly attached to the side walls of the filter element 3, keeping the filter element 3 stably installed inside the filter cartridge 2. When the filter element 3 needs to be disassembled and replaced, the sealing ring 8 is pried open to separate the sealing cover 4 from the inner side of the filter cartridge 2. At the same time, the rubber plate 11 also leaves the side wall of the filter element 3, releasing the limit on the filter element 3, and the filter element 3 can be removed from the limit rod 201, and then a new filter cartridge 2 can be installed.

[0035] In this embodiment, a fixing seat 12 is connected to the bottom end of the filter cartridge 2, an arc-shaped groove is provided on the side wall of the fixing seat 12, an arc-shaped rod 13 is connected to the inner wall of the arc-shaped groove, an arc-shaped sleeve 14 is correspondingly connected to the inner wall of the mounting groove 101, a limiting groove 1401 is provided on the inner side of the arc-shaped sleeve 14, and the arc-shaped rod 13 is inserted into the limiting groove 1401.

[0036] It should be noted that the fixing seat 12 at the bottom of the filter cartridge 2 is inserted into the interior of the mounting groove 101, and the filter cartridge 2 is rotated so that the arc rod 13 on its side wall is inserted into the interior of the limiting groove 1401, thereby fixing the position of the filter cartridge 2 inside the mounting groove 101.

[0037] In this embodiment, a limiting rod 201 is fixedly connected to the interior of the filter cartridge 2 , and the filter element 3 is sleeved on the exterior of the limiting rod 201 .

[0038] It should be noted that the filter element 3 is sleeved on the limiting rod 201 so that the filter element 3 is limited on the limiting rod 201 , so that the filter element 3 is limitedly installed at the middle position of the inner side of the filter cartridge 2 .

[0039] The working principle of the utility model is as follows: the fixing seat 12 at the bottom of the filter cartridge 2 is inserted into the interior of the installation groove 101, and the arc rod 13 on the side wall is inserted into the interior of the limiting groove 1401 by rotating the filter cartridge 2, so as to fix the position of the filter cartridge 2 in the installation groove 101, and then the filter element 3 is sleeved on the limiting rod 201, so that the filter element 3 is limited on the limiting rod 201, and then the sealing cover 4 is covered on the filter cartridge 2, and the sealing ring 8 is inserted into the interior of the filter cartridge 2. When the sealing ring 8 enters as a whole, the filter element 3 squeezes the rubber plates 11 on both sides, and the rubber plates 11 are pressed by the telescopic seat 9. The elastic compression of the spring 10 makes the rubber plate 11 fit firmly on the side wall of the filter element 3, keeping the filter element 3 stably installed inside the filter cartridge 2. When the filter element 3 needs to be disassembled and replaced, the sealing ring 8 is pried open to make the sealing cover 4 separate from the inner side of the filter cartridge 2. At the same time, the rubber plate 11 also leaves the side wall of the filter element 3, releasing the limit on the filter element 3. The filter element 3 can then be removed from the limit rod 201, and then a new filter cartridge 2 can be installed. After opening, the sealing cover 4 is elastically connected to the elastic rope 7, so that the sealing cover 4 always maintains the connection with the filter cartridge 2, which greatly facilitates the user's operation.

[0040] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
