The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

A high-efficiency filter, as shown in figures 1 to 4, comprises a filter box 1 and a flow blocking cover 2 in the filter box, wherein the flow blocking cover divides the interior of the filter box into an upper cavity and a lower cavity, the upper end of the flow blocking cover is fixed on the inner wall of the filter box, the lower end of the flow blocking cover is provided with an opening, and a front filtering channel 3 is formed between the outer wall of the flow blocking cover and the filter box. In an alternative embodiment, the upper end of the flow blocking cover is provided with an expanding section 14, the outer edge of the top end of the expanding section is welded and fixed with the inner wall of the filter box and keeps closed, the bottom of the filter box is provided with a lower end cover 4, and the top of the filter box is provided with an upper end cover 5; the lower end cover is provided with a discharge pipe 6, the upper end of the discharge pipe extends into the flow blocking cover, and a middle filtering channel 7 is formed between the discharge pipe and the inner wall of the flow blocking cover; an air gap 8 is reserved between the lower end of the flow blocking cover and the lower end cover.

The upper end cover and the lower end cover can be detachably arranged on the filter box, a front filter assembly 9 is arranged on a lower support 13 of the lower end cover, and a middle filter assembly 10 is arranged on an upper support 12 of the upper end cover. At least one inlet pipe 11 is provided in the filter box, the inner end of which communicates with the front filtering channel. In order to ensure the sealing performance of the filter, sealing gaskets are arranged between the upper end cover and the filter box and between the lower end cover and the filter box.

The discharge pipe is vertically arranged, and the air inlet at the upper end of the discharge pipe is positioned at the upper side of the middle filter assembly, so that the air entering the discharge pipe can be fully filtered by the front filter assembly and the middle filter assembly. For example, the discharge pipe is welded and fixed to a lower end cap, the upper end cap is fixed to the filter box by screws, and the lower end cap is fixed to the filter box by screws.

The front filtering component is detachably arranged on the lower support, and the middle filtering component is detachably arranged on the upper support.
