Description

Technical Field

[0001] The utility model belongs to the technical field of air purification filter elements, and in particular relates to an air purification filter element which is easy to replace. Background Art

[0002] The air purification filter element is a kind of filter, also called air filter cartridge, air filter, style, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms. The engine needs to inhale a large amount of air during operation. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Large particles entering between the piston and the cylinder will cause serious "cylinder pulling", which is particularly serious in dry and sandy working environments. The air filter is installed in front of the carburetor or the intake pipe to filter out dust and sand in the air to ensure that sufficient and clean air enters the cylinder.

[0003] However, when the air purification filter is used for a long time, a large amount of dust will be adsorbed on the surface, affecting the purification effect. The air purification filter needs to be replaced regularly. The existing air purification filter needs to disassemble the purification device when replacing it, which takes a lot of time and affects work efficiency. Therefore, an air purification filter that is easy to replace is needed to solve the problems existing in the prior art. Utility Model Content

By rotating the filter element outer cylinder 1 counterclockwise, the fixing block 203 is separated from the blocking block 105, thereby sliding upward to separate the connecting base 101 from the fixing base 201, thereby disassembling and separating the filter element outer cylinder 1 and the filter element inner cylinder 2, so that the internal dust can be cleaned in time, and when the activated carbon filter cartridge 205 needs to be replaced, the inner cylinder upper cover 206 is pulled upward, so that the activated carbon filter cartridge 205 is removed from the support rod 207 and replaced with a new activated carbon filter cartridge 205, so as to prevent the activated carbon filter cartridge 205 from being blocked by dust after long-term use and affecting the purification effect, thereby improving the convenience of disassembly of the device.

[0020] This scheme has the following working process: first, a brand new activated carbon filter cartridge 205 is sleeved on the fixed base 201 through the support rod 207, so that the inner cylinder cover 206 is connected and fixed to the support rod 207 through the fixing ring 211, so that the filter element outer cylinder 1 is sleeved on the top of the outer surface of the filter element inner cylinder 2, so that the bottom end of the connecting base 101 is slid into the inside of the connecting groove 202 so that the fixing block 203 enters the connecting bayonet 104, so that the filter element outer cylinder 1 is rotated clockwise so that the fixing block 203 is fixed in the connecting bayonet 104 through the blocking block 105, so that the filter element outer cylinder 1 and the filter element inner cylinder 2 are connected. They are fixed to each other, so that the air is double-filtered through the outer cylinder filter net 106 and the activated carbon filter cylinder 205. After long-term use, the filter inner cylinder 2 needs to be cleaned, so the filter outer cylinder 1 is rotated counterclockwise to separate the fixing block 203 from the blocking block 105, so that the filter outer cylinder 1 and the filter inner cylinder 2 are disassembled, so that the internal activated carbon filter cylinder 205 can be cleaned. When replacing the activated carbon filter cylinder 205, it is only necessary to pull up the inner cylinder upper cover 206 to separate the fixing ring 211 from the support rod 207, so as to replace the activated carbon filter cylinder 205 mounted on the support rod 207.

[0021] According to the above working process, it can be known that: through the filter element outer cylinder 1 and the filter element inner cylinder 2, the filter element outer cylinder 1 is sleeved on the outer surface of the filter element inner cylinder 2, so that the bottom end of the connecting base 101 slides into the interior of the connecting groove 202, so that the fixing block 203 enters the connecting bayonet 104, and the filter element outer cylinder 1 is rotated so that the outer surface of the fixing block 203 abuts against the top of the blocking block 105, so that the connecting base 101 and the fixing base 201 are fixed to each other, so that the filter element outer cylinder 1 is fixed to the outer surface of the filter element inner cylinder 2, thereby improving the stability of the utility model, and through the arrangement of the outer cylinder filter screen 106 and the activated carbon filter cylinder 205, the utility model can be fully used when in use.
