Adjustable filter with efficient purification function

Abstract

The invention relates to an adjustable filter with an efficient purification function, which comprises a frame body, a first filter screen is movably mounted in the frame body, a second filter screen is movably mounted at the bottom of the first filter screen, an adjusting assembly is arranged in the frame body, and a cleaning assembly is arranged on the frame body. A wind speed sensor body is arranged in the frame body and located below the adjusting assembly. According to the adjustable filter with the efficient purification function, a rotating wheel is rotated to drive a transmission shaft to rotate clockwise or anticlockwise, so that a worm rotates to drive a worm gear to rotate, and a rotating shaft rotates to drive a gear to rotate clockwise or anticlockwise; and thus, the rack moves rightwards or leftwards to drive the second filter screen to move rightwards or leftwards close to the bottom of the first filter screen, meshes of the first filter screen and meshes of the second filter screen are staggered, the density of the filter screens is adjusted, in this way, the operation mode is simple, a user can use the filter screen conveniently, and the applicability of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an adjustable filter with high-efficiency purification function. Background technique [0002] Filters include air filters. Air filters refer to air filtration devices, which are generally used in clean workshops, clean workshops, laboratories and clean rooms, or for dust prevention of electronic and mechanical communication equipment. There are primary filters, medium There are five types of high-efficiency filters, high-efficiency filters, sub-high-efficiency and high-efficiency filters, and each model has different standards and performance. [0003] According to the Chinese patent CN201920644737.5, a plate-type coarse-effect filter with resistance monitoring function is proposed. The number of layers and the density of the filter mesh in the filter can be adjusted by setting the coarse filter mesh and the fine filter mesh. According to the environment of use, Select the appr...
