Description

Technical Field

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

[0002] An air filter element is a type of filter, also known as an air filter cartridge or air cleaner. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms, and various precision operating rooms. According to the filtration principle, air filters can be divided into filter type, centrifugal type, oil bath type, and compound type. An air compressor is a device used to compress gas. Since the filter element will gradually accumulate dust and impurities during use, resulting in a decrease in the filtration effect, the air filter needs to be replaced and cleaned regularly to ensure the normal operation of the air compressor and extend its service life.

[0003] The existing filter element structure of the screw air compressor (Announcement No.: CN217473025U) uses a fixing frame and a limit component to firmly install the air filter element in the inner cavity of the air filter assembly, and then uses a stud and a spiral tube to firmly install the air filter cover on the top of the air filter assembly. Although the air filter element can be limited and clamped by a T-shaped slider and a limit card, only the top of the air filter element is limited, and the clamping effect is not ideal. In addition, when replacing the air filter element, the staff still needs to reach into the interior of the air filter assembly to take the air filter element, which makes it inconvenient to remove the air filter element and affects the replacement efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an air filter element for an air compressor.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An air filter element for an air compressor comprises an air filter assembly and a filter element main body, the filter element main body being located inside the air filter assembly, a sealing cover being movably provided on the top of the air filter assembly, a fixing bracket being fixedly installed at the inner center of the air filter assembly, a sliding rod 2 being fixedly provided on the side wall of one end of the fixing bracket close to the air filter assembly, a pressure block being movably installed on the sliding rod 2, a slot block being fixedly installed on the pressure block, a telescopic block being movably provided on the end of the slot block away from the pressure block, a spring 3 being fixedly installed between the telescopic block and the inner wall of the slot block, a mounting seat being fixedly provided on one end of the fixing bracket close to the sealing cover, a movable rod being movably installed on the mounting seat, and a limiting block being movably provided on the inner wall of the movable rod.

[0007] As a further solution of the present invention, the pressing block is slidably connected to the second slide bar, a second spring is sleeved on the second slide bar, and a first slide bar is fixedly provided on the inner wall of the movable rod.

[0008] As a further solution of the present invention, two ends of the second spring are respectively fixedly connected to the bottom of the pressing block and the inner wall of the mounting seat, and the limit block is slidably connected to the sliding rod 1.

[0009] As a further solution of the present invention, a spring is sleeved on the sliding rod, the limit blocks are symmetrically distributed on the fixing frame, and an inner screw tube is fixedly installed on the top of the fixing frame.

[0010] As a further solution of the present invention, the two ends of the spring 1 are respectively fixedly connected to the limit block and the side wall of the movable rod, and the inner wall of the cover is fixedly provided with a stud, which is threadedly connected to the inner spiral tube.

[0011] As a further solution of the present invention, the telescopic blocks are symmetrically distributed on the fixing frame, and a connecting pipe is fixedly installed on the outer side wall of the air filter assembly.

[0012] Compared with the prior art, the present invention has the following beneficial effects: when in use, with the cooperation of the mounting seat, the staff pulls the movable rod upward to deflect and place the filter element body into the air filter assembly, and supports the bottom of the filter element body through the card slot block. When the filter element body moves down into the interior of the air filter assembly, the card slot block is squeezed to move downward, driving the pressure block to squeeze the spring 2 to produce deformation, and under the action of the spring 3, the telescopic block is pushed to limit the bottom end of the filter element body, and then the movable rod is pulled downward, and the elasticity of the spring 1 is used to make the limit block limit the upper end of the filter element body again, and the limit block and the telescopic block are in the same position. There are two groups of them inside the air filter assembly. Finally, the staff uses tools to engage the cover with the air filter assembly, and at the same time drives the stud to connect with the inner screw tube, so that the filter element body is sealed and installed inside the air filter assembly. When the filter element body needs to be disassembled and replaced, the staff pulls the limit block away from the filter element body, and with the cooperation of the mounting seat, pulls the movable rod upward to loosen the upper end limit of the filter element body, so that the spring 2 compressed at the bottom releases energy, rebounds and pushes the slot block upward, thereby driving the filter element body out of the air filter assembly, making it easier for the staff to take it out and replace it, thereby improving the flexibility of use.

[0023] When in use, with the cooperation of the mounting seat 102, the staff pulls the movable rod 6 upward to deflect and place the filter element main body 2 into the air filter assembly 1, and supports the bottom of the filter element main body 2 through the slot block 106. When the filter element main body 2 moves down into the interior of the air filter assembly 1, the slot block 106 is squeezed to move downward, driving the pressure block to squeeze the spring 203 303 to produce deformation, and under the action of the spring 3 4, the telescopic block 5 is pushed to limit the bottom end of the filter element main body 2, and then the movable rod 6 is pulled downward, and the elasticity of the spring 1 105 is used to make the limit block 103 limit the upper end of the filter element main body 2 again. The limit block 103 and the telescopic block 5 are both in the air filter assembly 1. There are two groups of parts.

[0031] During use, the staff rotates the cover 3 with a wrench to separate the stud 301 from the inner screw tube 302 , thereby removing the cover 3 .

[0034] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: with the cooperation of the mounting seat 102, the staff pulls the movable rod 6 upward to deflect and place the filter element body 2 into the air filter assembly 1, and supports the bottom of the filter element body 2 through the card slot block 106. When the filter element body 2 moves down into the interior of the air filter assembly 1, the card slot block 106 is squeezed to move downward, driving the pressure block to squeeze the spring 203 303 to produce deformation, and under the action of the spring 3 4, the telescopic block 5 is pushed to limit the bottom end of the filter element body 2, and then the movable rod 6 is pulled downward, and the elasticity of the spring 1 105 is used to make the limit block 103 limit the upper end of the filter element body 2 again, and the limit block 1 03 and telescopic block 5 are both provided with two groups inside the air filter assembly 1.
