[0002] A filter cartridge is a cylindrical element used for filtering. It is generally divided into filter cartridges for filtering gaseous media and filtering liquid media. It is mainly filtered through an internal filter element. The filter element is mainly used in oil filtration, air filtration, water filtration and other filtration industries. The filter element separates solid particles in liquid or gas, or allows different material components to fully contact, speeding up the reaction time, and protecting the normal operation of the equipment or the cleanliness of the air.

[0003] The problem with the prior art is that when the filter cartridge is used, impurities and harmful substances in the air are cleaned through the filter element. Due to long-term use, impurities and harmful substances will adhere to the surface of the filter element and reduce the filtering effect. However, the existing filter elements are disposable products and cannot be disassembled and cleaned separately, which increases maintenance costs. In order to facilitate the cleaning of the filter element and reduce maintenance costs, a filter cartridge with a built-in filter element is proposed. When cleaning the filter cartridge, it is convenient for the staff to disassemble the filter element and extend the service life of the filter cartridge. Utility Model Content

[0023] refer to Figure 3 The adjustment mechanism 6 includes a moving rod 601, a fixed column 602 and a bent rod 603. The top of the moving rod 601 passes through the top of the sealing cover 4, and the bottom of the moving rod 601 passes through the interior of the positioning cavity 5. The top of the moving rod 601 is fixedly connected to the bottom of the fixed column 602, and the top of the fixed column 602 passes through the top of the bent rod 603. The bent rod 603 is movably connected to the interior of the positioning cavity 5 through a rotating shaft, and the bent rod 603 is used in conjunction with the positioning mechanism 7.

[0024] The above scheme is adopted: by setting up the adjustment mechanism 6, the movable rod 601 can be pulled, the movable rod 601 drives the fixed column 602 to move, and the fixed column 602 drives the bent rod 603 to rotate, so that when the staff disassemble and adjust the filter element 3, it is convenient for the staff to operate and the operation method is simplified.

[0025] refer to Figure 3 The positioning mechanism 7 includes a vertical rod 701, a positioning rod 702 and a compression spring 703. The surface of the bent rod 603 contacts the surface of the vertical rod 701. The rear side of the vertical rod 701 is fixedly connected to the front side of the positioning rod 702. The right side of the positioning rod 702 is fixedly connected to the left side of the compression spring 703. The right side of the compression spring 703 is fixedly connected to the inner wall of the positioning cavity 5. The left side of the positioning rod 702 penetrates into the interior of the filter element 3.

[0026] By adopting the above solution, by providing the positioning mechanism 7, the filter element 3 can be stably fixed inside the housing 2 when it is installed, so as to prevent it from loosening during use and causing damage to the filter element 3.

[0027] refer to Figure 3 and Figure 4 A fixing groove 8 is provided on the surface of the filter element 3, and the diameter of the fixing groove 8 is equal to the diameter of the positioning rod 702, and the positioning rod 702 is in close contact during insertion.

[0028] By adopting the above solution, by providing the fixing groove 8, the positioning rod 702 can be accurately inserted into the fixing groove 8 during plugging and fixing, so that it can be stably fixed and prevented from loosening.

[0029] refer to Figure 3A limiting block 9 is fixedly connected to the interior of the positioning cavity 5 , and the limiting block 9 is sleeved on the surface of the positioning rod 702 .

[0030] By adopting the above solution, by setting the limiting block 9, the positioning rod 702 can be moved according to the moving track provided by the limiting block 9, thereby ensuring the normal use of the structure.

[0031] refer to Figure 3 A travel groove 10 is opened at the top of the bending rod 603, and the fixed column 602 moves along the opening direction of the travel groove 10.

[0032] By adopting the above solution, the travel groove 10 is provided to limit the moving direction and travel of the fixing column 602, thereby preventing the travel from exceeding the limit during use and causing structural damage.

[0033] refer to Figure 3 The left and right sides of the moving rod 601 are fixedly connected to the limiting rod 11, and the interior of the positioning cavity 5 is provided with a limiting groove 12 used in conjunction with the limiting rod 11.

[0034] By adopting the above solution, by providing the limiting rod 11 and the limiting groove 12, the moving rod 601 can be moved in the direction of the limiting groove 12, thereby ensuring the normal use of the overall structure and preventing damage.

[0035] The working principle of this utility model:

[0036] When in use, the moving rod 601 is pulled forward, and the moving rod 601 drives the fixed column 602 to move forward according to the moving trajectory provided by the limit groove 12. The surface of the fixed column 602 squeezes the inner wall of the travel groove 10 to make the bent rod 603 rotate clockwise with the rotating shaft as the center. During rotation, the surface of the bent rod 603 squeezes the surface of the vertical rod 701 to make the vertical rod 701 move to the right, and the vertical rod 701 drives the positioning rod 702 to move to the right according to the moving trajectory provided by the limiting block 9. The positioning rod 702 compresses the compression spring 703 while moving to the right, so that the positioning rod 702 moves to the inside of the positioning cavity 5, and the same operation is performed on the other side. At this time, the sealing cover 4 can be disassembled, and the filter element 3 can be taken out for cleaning or replacement after disassembly. After completion, the moving rod 601 is released, and the positioning rod 702 is reinserted into the inside of the fixed groove 8 through the resilience of the compression spring 703, so that it is stably fixed to prevent loosening.

[0037] To sum up: the filter cartridge with built-in filter element, by setting the base 1, shell 2, filter element 3, sealing cover 4, positioning cavity 5, adjustment mechanism 6, moving rod 601, fixed column 602, bending rod 603, positioning mechanism 7, vertical rod 701, positioning rod 702, compression spring 703, fixed groove 8, limiting block 9, travel groove 10, limit rod 11 and limit groove 12, solves the problem that when the filter cartridge is used, impurities and harmful substances in the air are cleaned through the filter element. Due to long-term use, impurities and harmful substances will adhere to the surface of the filter element and reduce the filtering effect. However, the existing filter elements are disposable products, and the filter elements cannot be disassembled and cleaned separately, which increases the maintenance cost. In order to facilitate the cleaning of the filter element and reduce the maintenance cost, a filter cartridge with built-in filter element is proposed, which is convenient for the staff to disassemble the filter element when cleaning the filter cartridge and prolong the service life of the filter cartridge.
