Description

Air purifier filter core structure convenient to loading and unloading filter screen Technical Field The utility model belongs to the technical field of air purification equipment, and particularly relates to an air purifier filter element structure convenient for loading and unloading a filter screen. Background The air purifier is used as a key device for improving indoor air quality, and the core function of the air purifier depends on the filtering effect of the filter element on harmful substances such as particulate matters, gaseous pollutants and the like in the air. In the prior art, the filter element is designed in a cylindrical or plate type structure, wherein the cylindrical filter element occupies the mainstream in the market due to the large effective filtering area and the low wind resistance characteristic. However, the conventional cylindrical filter element is generally designed into an integrated structure in terms of structure, so that the filter screen is difficult to be detached independently, and in the transportation process, the filter screen needs to maintain the unfolded form, so that the problem of large transportation volume exists, and the transportation cost is increased. Disclosure of utility model The utility model provides an air purifier filter element structure convenient for assembling and disassembling a filter screen aiming at the problems existing in the prior art. The utility model can be realized by the following technical scheme: An air purifier filter core structure convenient to loading and unloading filter screen includes: the bracket comprises a supporting main body and a base which are connected; the filter screen is sleeved on the periphery of the supporting main body; A top cover connected with the end surface of the supporting main body far away from the base through a detachable connecting structure, wherein, When the top cover is installed, the top cover and the base form axial restraint of the filter screen along the two axial ends of the supporting main body; When the top cover is disassembled, the filter screen is separated from and removed along the axial direction of the supporting main body. As a further development of the utility model, the screen is composed of a layer of flexible material and has a flexible deformation characteristic of being foldable and compressible. As a further improvement of the utility model, the utility model further comprises a carbon net which is arranged on the inner ring of the filter screen and sleeved on the supporting main body.
