Description

Air filter element structure Technical Field The application relates to air filter element equipment, in particular to an air filter element structure. Background The air filter element is a filter, also called air filter cartridge, air filter, style, etc., and is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operating rooms and various precision operating rooms. The main body of the air filter element is mainly folded into a cylinder by adopting filter paper, then fixing buckles, such as a strap, are installed on the outer part of the main body of the filter element, so that the main body of the filter element is prevented from being broken, and the filter element is required to be evenly separated from folds of the main body of the filter element, such as the device disclosed in patent CN212632133U, although the main body of the filter element can be fixed and evenly separated, the main body of the filter element is easy to be dissociated in the use process, so that a plurality of buckles on the main body of the filter element are easily accumulated in one place, the main body of the filter element is fixed unevenly, and in order to solve the problem, fixing members are required to be installed on the main body of the filter element, so that the device is fixed on the main body of the filter element, but the capability of the device for evenly separating the folds of the main body of the filter element is limited, so that the folds of each part of the main body of the filter element cannot be well evenly separated. Disclosure of Invention In order to solve the technical problems, the application provides an air filter element structure, which is characterized in that a filter element main body is fixed by utilizing a connecting strip, and a buckle is clamped in a clamping groove on the connecting strip, so that the buckle can fix the connecting strip and the filter element main body and uniformly separate folds on the filter element main body, and the air filter element structure is simple in structure, convenient to use, efficient and labor-saving. The application provides an air filter element structure, which adopts the following technical scheme: an air filter cartridge structure comprising: the filter element main body is cylindrical, and a plurality of folds are uniformly formed on the outer side face along the axial direction; The connecting strip is arranged at the joint of the filter element main body and used for fixing the filter element main body; the clamping groove is formed in the connecting strip; The buckle is sleeved on the filter element main body and is clamped in the clamping groove, and the buckle is used for fixing the filter element main body and the connecting strip and uniformly separating the filter element main body. Preferably, the section of the connecting strip is V-shaped, and the inner wall of the connecting strip is fixed with the filter element main body. Preferably, the number of the clamping grooves is multiple, and each clamping groove is provided with a buckle. Preferably, the plurality of clamping grooves are uniformly distributed on the connecting strip. Preferably, the buckle includes separating ring and solid fixed ring, the inside shaping of separating ring has the separation protruding the same with fold recess quantity on the filter core main part, and every separate protruding one-to-one set up in the fold recess of filter core main part, separating ring joint is in the draw-in groove, gu fixed ring locates separating ring's outer lane and is used for fixed separating ring. Preferably, the two ends of the separating ring in the axial direction are provided with a skirt part, and the skirt part is positioned at one side of the separating ring far away from the filter element main body. In summary, the application has the following beneficial technical effects: 1. According to the application, the filter element main body is fixed by the connecting strip, and the buckle is clamped in the clamping groove on the connecting strip, so that the buckle can fix the connecting strip and the filter element main body and uniformly separate the folds on the filter element main body, and the filter element main body has the advantages of simple structure, convenience in use, high efficiency and labor saving. 2. This is applied through set up a plurality of buckles on the connecting strip for it can be better fix filter core main part, has improved filter core main part's stability. 3. According to the application, the skirt parts are arranged on the two sides of the separating ring, so that when the filter element main body needs to be cleaned and blown in the reverse direction, the skirt parts can support the bulged filter element main body, and the edge of the separating ring is not easy to scratch or crush the filter element main body.
