Abstract

The invention discloses a double-layer filter group which comprises a box body, a filter and an air inlet pipe. A water blocking plate is arranged in the box body, a filter mounting rack is arranged on the water blocking plate, the filter is installed on the filter mounting rack, a water blocking net is arranged below the water blocking plate, a water storage cavity is formed below the water blocking net, the air inlet pipe penetrates through the water blocking net, the tail end of the air inlet pipe is located in the water storage cavity, and the head end of the air inlet pipe is communicated with the outside. The double-layer filter group is not easily blocked.

Description

Technical field [0001] The invention relates to a double-layer filter group and a vacuum cleaner. Background technique [0002] Vacuum cleaners can be divided into vertical, horizontal and portable according to their structure. The working principle of the vacuum cleaner is to use a motor to drive the blades to rotate at a high speed, generate negative air pressure in the sealed casing, and absorb dust. [0003] The filter group of a vacuum cleaner is generally composed of a dust bag, a front filter and a rear filter. According to different filter materials, it is divided into paper and cloth. [0004] When the filter unit of the vacuum cleaner collects and processes oily dust, the oily dust easily adheres to the dust bag, the front filter and the rear filter, causing the filter unit to block and easily make the vacuum cleaner not work properly. Summary of the invention [0005] The technical problem to be solved by the present invention is to provide a double-layer filter unit tha...
