Air filter with filter element convenient to replace

Abstract

The air filter comprises a filter shell, an air inlet, an air outlet, an air inlet channel and a filter element structure, the air inlet and the air outlet are formed in the upper portion of the filter shell, the filter element structure is arranged in the filter shell, the air inlet and the air inlet channel are installed in a sealed mode, and the air outlet and the air inlet channel are installed in a sealed mode. The other end of the filter element structure and the air outlet are installed in a sealing fit mode. A sealing cover structure is further arranged at the top end of the filter shell, and a dust discharging opening is formed in the lower end of the filter shell. When the engine works, the air filter sucks air from the outside through the air inlet connected with the air inlet pipeline, the sucked air is filtered when the air passes through the filter element structure, and the air without foreign matter is exhausted through the air outlet to be used by the machine. When the filter element adsorbs a large amount of dust, the filter element can be replaced by unscrewing the top sealing cover, and the dust can be discharged through the discharge port. The air filter with the filter element convenient to replace has the advantages that the pipeline is not disassembled, the structure is simple, the use is convenient, the filter element is convenient to replace, and impurities are convenient to clean.

Description

Technical Field

[0001] The invention relates to the technical field of filters, and in particular to an air filter with a convenient filter element replacement. Background Art

[0002] An air filter is an item that removes particulate impurities from the air, provides clean air for mechanical equipment, and prevents mechanical equipment from inhaling air containing impurities during operation, which increases wear and loss.

[0003] However, it is not convenient to replace the filter element or remove the filter element for cleaning and maintenance after long-term use. The air filter needs to be removed from the machine first, and then the air filter housing is disassembled to take out the filter element, and then the filter element is replaced and installed again. The whole process is complicated, which makes the maintenance process inefficient. Repeated disassembly and assembly of the air filter can easily cause the subsequent installation to become loose, or even worse, cause insufficient sealing, causing the air filter to be scrapped prematurely.

[0004] Therefore, it is necessary to provide a new filter element to be convenient to replace the air filter to solve the above-mentioned problems. Summary of the invention

[0005] The technical problem solved by the present invention is to provide an air filter with a simple structure, easy replacement of filter elements and easy cleaning of impurities without disassembling pipelines, thereby solving the problem that filter elements are not easy to replace.

[0006] In order to solve the above technical problems, the present invention provides an air filter with convenient filter element replacement, comprising a filter housing, an air inlet, an air outlet, an air inlet channel and a filter element structure, the air inlet and the air outlet are arranged at the upper position of the filter housing, the filter element structure is arranged inside the filter housing, the air inlet is sealed and installed with the air inlet duct, and the other end of the filter element structure is sealed and installed with the air outlet; a sealing cover structure is also arranged at the top of the filter housing, and a dust discharge port is arranged at the lower end of the filter housing.

[0007] When the engine is working, the air filter draws in air from the outside through the air inlet connected to the air inlet duct, filters the inhaled air when passing through the filter element structure, and then discharges the air without foreign matter through the air outlet for use by the machine. When the filter element absorbs a lot of dust, unscrew the top sealing cover to replace it, and the dust can be discharged to the outside through the discharge port.

[0008] Furthermore, the sealing cover is arranged on the top of the air filter.

[0009] Furthermore, the air inlet and the air outlet are arranged on the upper part of the air filter.

[0010] Furthermore, a dust outlet is provided at the lower portion of the air filter.

[0011] The beneficial effects of the present invention are that the pipeline does not need to be disassembled, the structure is simple, the use is convenient, the filter element is easy to replace, the impurities are easy to clean, and time and labor are saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] See also Figure 1 , the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] The present invention provides an air filter with convenient filter element replacement, comprising a filter housing 5, an air inlet 3, an air outlet 4, an air inlet channel 2 and a filter element structure 6, wherein the air inlet 3 and the air outlet 4 are arranged at the upper position of the filter housing 5, the filter element structure 6 is arranged inside the filter housing 5, the air inlet 3 is sealed and installed with the air inlet duct 2, and the other end of the filter element structure 6 is sealed and installed with the air outlet 4; a sealing cover structure 1 is also arranged at the top of the filter housing 5, and a dust discharge port 7 is arranged at the lower end of the filter housing 5.

[0015] When the engine is working, the air filter inhales air from the outside through the air inlet 3 connected to the air inlet duct 2, filters the inhaled air when passing through the filter element structure 6, and the air without foreign matter is discharged through the air outlet 4 for use by the machine. When the filter element 6 absorbs a lot of dust, the top sealing cover 1 can be unscrewed to replace it, and the dust can be discharged to the outside through the discharge port 7.

[0016] Furthermore, the sealing cover is arranged on the top of the air filter.

[0017] .Furthermore, the air inlet and the air outlet are arranged on the upper part of the air filter.

[0018] Furthermore, a dust outlet is provided at the lower portion of the air filter.

[0019] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
