Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air compressor which is convenient for replacing an air filter element. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. An air compressor provides air source power and is the core equipment of a pneumatic system. It is the main body of an electromechanical air source device. It is a device that converts the mechanical energy of a prime mover (usually an electric motor or a diesel engine) into gas pressure energy. It is a compressed air pressure generating device. Currently, the air intake end of existing air compressors is equipped with an air filter element to facilitate filtering impurities in the air when inhaling air. The air filter element needs to be replaced after long-term use.

[0003] According to the Chinese patent announcement number: CN219299488U, an air compressor that is easy to replace the air filter is disclosed. The air intake pipe, the movable ring and the limit block cooperate with each other. A movable movable ring is provided on the outside of the air intake pipe, which is convenient for the staff to quickly replace the air filter without disassembling the air intake pipe, saving time and manpower, and improving the replacement efficiency of the air filter of the air compressor. In this technical solution, when replacing the filter element, the staff must carry a new filter element, and the connection between the filter element and the air intake pipe is relatively tight. It is not convenient for the staff to take out and install the filter element through the through hole, which makes the replacement of the filter element more difficult. For this reason, we propose an air compressor that is easy to replace the air filter element. Utility Model Content

[0024] Embodiment 1:

[0025] The preferred embodiment of the air compressor provided by the utility model, which is convenient for replacing the air filter element, is as follows Figures 1 to 5 As shown: an air compressor that is easy to replace an air filter element, comprising an air compressor body 1, an air intake pipe 1 2 and an air intake pipe 2 3, the air intake pipe 1 2 is connected to the input end of the air compressor body 1, and a filter element replacement mechanism 4 is arranged between the air intake pipe 1 2 and the air intake pipe 2 3;

[0026] The filter element replacement mechanism 4 includes a U-shaped connecting rod 401, a rotating plate 402 and a threaded sleeve 412. The two ends of the U-shaped connecting rod 401 are fixedly mounted on the outer walls of the intake pipe 1 2 and the intake pipe 2 3 respectively. A rod hole 403 is opened on the rotating plate 402. The U-shaped connecting rod 401 movably penetrates the rod hole 403. A torsion spring 404 is fixedly connected between the outer wall of the U-shaped connecting rod 401 and the inner wall of the rod hole 403. A filter element tube 405 is fixedly mounted on the top of the rotating plate 402. The filter element tube 405 is plugged with a filter element. Body 406, filter tube 405 is provided with external thread 2 408 on the outer wall near both ends, air inlet pipe 1 2 and air inlet pipe 2 3 are provided with external thread 1 407 on the outer wall near the opposite end, threaded sleeve 412 is threadedly connected with air inlet pipe 1 2 and filter tube 405 through external thread 1 407 and external thread 2 408 respectively, sealing gaskets 413 are fixedly installed at both ends of filter tube 405, a placing cylinder 410 is fixedly installed at the bottom end of rotating plate 402, and cylinder covers 411 are clamped at both ends of placing cylinder 410.

[0027] Specifically, in the above technical solution, when the filter element body 406 needs to be replaced, the two threaded sleeves 412 are rotated to disengage the two threaded sleeves 412 from the filter element tube 405, and then the rotating plate 402 can be rotated forward, the rotating plate 402 twists the torsion spring 404, and the rotating plate 402 drives the filter element to disengage from the intake pipe 1 2 and the intake pipe 2 3. Then, the filter element body 406 that needs to be replaced in the filter element tube can be taken out from one end, and then the new filter element prepared in advance in the placement cylinder 410 can be inserted into the filter element tube, and then the rotating plate 402 is released. At this time, the rotating plate 402 will rotate backward under the restoring force of the torsion spring 404, and when the rotating plate 402 contacts the magnetic plate 2 7, When magnetic plate 1 6 is magnetically connected with magnetic plate 2 7, rotating plate 402 just drives the filter element tube with the new filter element to be located between intake pipe 1 2 and intake pipe 2 3, and then the two threaded sleeves 412 are rotated in the opposite direction to connect the threaded sleeves 412 with the filter element tube, thereby completing the replacement of the filter element. This mechanism makes it easy for personnel to replace the filter element, and by preparing spare filter elements in advance, the replacement efficiency of the filter element can be greatly improved, which solves the problem in the prior art that personnel must carry a new filter element when replacing the filter element, and the connection between the filter element and the intake pipe is relatively tight, and it is inconvenient for personnel to take out and install the filter element through the through hole, resulting in difficulty in replacing the filter element.

[0028] Furthermore, retaining rings 409 are fixedly sleeved near both ends of the outer wall of the filter tube 405, and the sealing gasket 413 is made of wear-resistant rubber;

[0029] Among them, by setting the retaining ring 409, the threaded sleeve 412 can be limited and blocked, and by setting the sealing gasket 413, the sealing between the filter element tube 405 and the intake pipe 1 2 and the intake pipe 2 3 can be increased.

[0030] Furthermore, grilles 8 are fixedly installed on the inner walls of the air intake pipe 1 2 and the air intake pipe 2 3 near the opposite ends.

[0033] The rotating plate 402 can be limited by setting the baffle 5.

[0034] Specifically, the above technical solution is that by setting magnetic plate 2 7 and magnetic plate 1 6, the rotating plate 402 can be positioned, thereby improving the accuracy of the connection position between the filter element tube 405 and the intake pipe 1 2 and the intake pipe 2 3 when resetting, which is convenient for personnel to operate, has a simple structure and strong practicality.

[0035] Furthermore, the magnetic properties of the opposite surfaces of magnetic plate 1 6 and magnetic plate 2 7 are opposite.
