In addition, the filter is difficult to clean, which leads to a rapid shortening of its service life.

Task

One of the purposes of the embodiments of the present application is to provide a cyclone dedusting structure and a vacuum cleaner to solve the problem of easy clogging and short life of a filter.

The electric motor is used to create a negative pressure in the vacuum cleaner so that the suction head assembly 3 Dust particles on the floor can be sucked into the interior of the vacuum cleaner and a swirling flow of air in the cyclone dedusting structure 1 is generated to remove dust particles from the inhaled airflow, after which the airflow through the filter 2 is drained. The filter 2 is with that of the third inner cylinder 14th far end of the vortex cylinder 15th connected. That is, the filter 2 is at the tertiary air outlet of the tertiary cyclone chamber 301 arranged.

The vacuum cleaner in the above embodiment uses the cyclone type dedusting structure 1 in one of the above embodiments, wherein the cyclone dedusting structure 1 a primary cyclone chamber 101 , a secondary cyclone chamber 201 and a tertiary cyclone chamber 301 and dust particles can be deposited three times in the dirty air sucked in, causing them to enter the filter 2 the amount of dust entering is significantly reduced. And the filter 2 is on the vortex cylinder 15th located and further from the tertiary dust collection chamber 302 removed so that the dust particles are not easily under the influence of the air flow into the filter 2 get what the life of the filter 2 extend and the frequency of filter changes in the vacuum cleaner 2 can decrease.

Optionally includes, as in 12th shown, the suction head assembly 3 a suction head housing 31 and a side brush 32 that are rotatable with the suction head housing 31 connected, with the side brush 32 on the edge of the suction head housing 31 is arranged to clean the hard-to-reach areas. The number of side brushes 32 is not limited here. In every corner of the suction head housing 31 can be a side brush 32 to be ordered. The side brush 32 includes a hub 321 and several bristles 322 that are in the circumferential direction on the outer circumference of the hub 321 are arranged. When operating the vacuum cleaner, the hub 321 the side brush 32 rotated so that the bristles 322 be rotated to clean hard-to-reach areas to improve the cleaning performance of the vacuum cleaner.

The filter is optional 2 in rotary snap connection with the cyclone dedusting structure 1 so that the dismantling of the cyclone dedusting structure 1 for dust cleaning is facilitated. This is on the housing of the filter 2 a first buckle portion is arranged, wherein on the outer cylinder 11 the cyclone dedusting structure 1 a second buckle portion is disposed, the first buckle portion being in rotational snap connection with the second buckle portion.

Above are only optional exemplary embodiments of the present application, which do not serve to restrict the present application. Various modifications and changes to the present application can be made to those skilled in the art. All modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application are intended to be included within the scope of the claims of the present application.
