Embodiment Construction

[0021] Such as figure 1 with figure 2 Shown is a vacuum cleaner according to an embodiment of the present invention, which includes a head assembly 5, an air inlet 6, a dust bucket 7 and a filter assembly. The head assembly 5 is arranged above the dust bucket 7, and a motor 51 is arranged inside the head assembly 5. The motor 51 drives the impeller 54 to suck the airflow and suck the external dust into the vacuum cleaner. The drive impeller 54 is located in the impeller chamber 541. The filter assembly includes a filter 8 and a bracket 9. When the vacuum cleaner is working, the air flow enters the dust bucket through the air inlet 6 on the dust bucket 7, passes through the filter 8 to filter out the dust mixed in the airflow, and then the airflow passes through the machine head The air inlet 55 below the assembly 5 enters the air duct in the head assembly 5 . The bracket 9 is installed under the head assembly 5 , and the filter 8 is sleeved on the outside of the bracket 9 ....

Abstract

A vacuum cleaner comprises a head component, a dust barrel and a filter component, wherein the filter component is installed below the head component; the dust barrel and the head component can be separated or adapted; an airflow inlet is formed in the head component; the filter component comprises a support and a filter; the filter is arranged outside the support in a sleeving manner; an airflow buffer area is arranged between the support and the filter; a buffer area inlet and a buffer area outlet are arranged in the airflow buffer area; the buffer area inlet is communicated or not communicated with a bypass channel in the head component through a valve; the buffer area outlet is communicated with the airflow inlet. According to the vacuum cleaner, the airflow buffer area is arranged inside the filter component, duration of clearing airflow in the filter component is prolonged, the clearing airflow is spread in the filter to a certain extent and does not flow directly back into a motor, the pressure difference between the inside and outside of the filter is reduced, the cleaning effect is better, the structure is simple, and manufacturing cost is low.

Description

technical field [0001] The invention relates to a vacuum cleaner. Background technique [0002] When the vacuum cleaner is working, dust is sucked into the interior of the vacuum cleaner along with the airflow, and a filter is set inside the vacuum cleaner to filter out the dust in the airflow. After the vacuum cleaner works for a long time, the dust continuously attached to the filter will block the filter, which will reduce the dust collection ability of the vacuum cleaner and affect the cleaning effect of the vacuum cleaner. In the prior art, filter dust is cleaned by setting a dust cleaning structure. According to the cleaning method, it can be roughly divided into contact type and non-contact type. The contact type generally has cleaning accessories such as manual scraping strips, manual brush strips, and rotating brush strips. Acting directly on the filter, in addition to the manual method, there are also mechanical vibration and electromagnetic vibration mech...
