Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Fig. 1 shows a schematic structure of a vacuum cleaner according to an embodiment of the present application. Referring to fig. 1, the method comprises: the filter cartridge comprises a cylinder body 10, a filter cartridge 20, a filter cartridge upper cover 30, a dust removing hose 40 and a negative pressure assembly 50.

The filter bin 20 is arranged in the cylinder 10, and a filter 201 is arranged in the filter bin 20; a filter house upper cover 30 is arranged at the top opening of the filter house 20. The filter bin upper cover 30 is provided with a negative pressure connecting hole 302 and a self-cleaning hole 301; the negative pressure connecting hole 30 is communicated with the negative pressure assembly 50, and the self-cleaning hole 301 is provided with a pulse valve 60; the cylinder 10 is provided with an air inlet 101 connected with a dust removing hose 40, and the dust removing hose 40 is provided with an air inlet regulating valve 401.

When in the dust collection mode, the pulse valve 60 is closed, and the air inlet regulating valve 401 is opened; the dust removing hose 40, the air inlet 101, the outside of the filter 201, the inside of the filter 201, the negative pressure connection hole 302 and the negative pressure assembly 50 form an air passage therebetween. In this mode, the cleaner is in a normal operation state, i.e., air is mixed with dust and the like, and the air is filtered by passing through the air inlet regulating valve 401, the dust removing hose 40, the air inlet 101, the air, the dust and the like, and then returned to the atmosphere through the negative pressure connection hole 302 and the negative pressure assembly 50.

When in the self-cleaning mode, the intake regulating valve 401 is closed and the pulse valve 60 is intermittently opened; air channels are formed among the self-cleaning holes 301, the inside of the filter 201, the outside of the filter 201, the negative pressure connection holes 302 and the negative pressure assembly 50. In this mode, the air inlet 101 of the cleaner is blocked, the negative pressure assembly 50 continues to draw air from the filter cartridge 20 through the negative pressure connection hole 302 in the upper cover of the filter cartridge 20, but the air inlet of the filter cartridge 20 is blocked and no air enters, and the air in the filter cartridge 20 is quickly drawn out, creating a vacuum. At this time, the pulse valve 60 mounted on the upper cover 30 of the filter house assists in air intake, that is, is instantaneously opened and air is taken in under the action of negative pressure, and air flow formed by the air intake instantaneously strikes the inside of the filter 201 and penetrates through the filter 201 to blow off dust adhered to the outside of the filter 201, thereby realizing disassembly-free self-cleaning of the filter 201.

It can be seen that the dust collector provided by the application is provided with the air inlet regulating valve 401 on the dust removing hose 40, the self-cleaning hole 301 on the filter house upper cover 30 and the pulse valve 60 on the self-cleaning hole 301. In the use process, the pulse valve 60 of the filter house upper cover 30 is opened and closed between the air inlet adjusting valve 401, and a regular cycle of opening and closing is formed, so that pulses are formed.
