Description

Filter element capable of adjusting wind resistance Technical Field The utility model relates to the technical field of automobile filter elements, in particular to a filter element with adjustable wind resistance. Background The automobile filter element is a core component of an automobile filtering system, and is mainly intercepted through fiber materials to remove impurities in different media, so that an engine and the environment in an automobile are protected, the wind resistance of the filter element directly influences the energy consumption of the system, the greater the wind resistance is, the stronger the power required when air passes through the filter element is, the more energy is required to be consumed by an air pump or a fan to maintain the air flow, the proper wind resistance can optimize the air flow distribution, and the filtering efficiency is improved. Traditional automobile filter core mostly adjusts the windage of filter core through the size that opens and shuts of valve control filter core department air intake, but these modes can produce some drawbacks, for example, when its air intake of filter core department opened and shut the regulation of size, the intermediate layer department of inside and outside air intake can produce the dust, although can set up the sealing washer between traditional inside and outside air intake and seal dustproof, but the sealing washer leads to the fact wearing and tearing because of the friction in the accommodation process of inside and outside air intake easily to can not only influence the dustproof effect of sealing washer, and the sealing washer itself leads to the fact the damage easily, consequently, proposes a filter core of adjustable windage to above-mentioned problem. Disclosure of utility model The utility model aims to provide a filter element with adjustable wind resistance, which not only can ensure the dustproof effect between an outer shell and an inner shell through a filling air bag, but also can reduce the contact friction on the filling air bag in the adjusting process of the opening and closing degree between the outer shell and the inner shell, thereby not only ensuring the dustproof effect of the filling air bag, but also ensuring that the filling air bag is not easy to damage, so as to solve the problems in the prior art.
