Description
Technical field
The present invention relates to cleaner field, in particular to a kind of motor base for extra large pa self-cleaning dust catcher.
Background technique
The working principle of dust catcher is, using motor band movable vane piece high speed rotation, to generate air in the shell of sealing
Negative pressure draws the body surfaces such as carpet, floor, the wall with dust, and dust is as air is by sucking dust and gas separation together
After in component, dust is filtered by the extra large pa in dust and gas separation assembly and collected by dust bucket, and filtered pure air is then
It is excluded outside dust catcher body.
After a period of operation, the Adsorption on Surface for being located at dust bucket side has a large amount of dusts to extra large pa, and dust is a large amount of
Being attached to extra large pa surface can be by the small filtering sieve pore blockade on extra large pa surface, and then influences the filter capacity of extra large pa, existing market
On dust catcher product there are the following problems：On the one hand, existing dust catcher, which lacks, carries out self-cleaning function to extra large pa,
Extra large pa directly carry out extra large pa after patting debris removal or tearing machine open after the general extra large pa blockage problem of generation or after tearing machine open
Renew, no matter which kind of mode will all spend a large amount of clearance times, and the latter will result directly in the alternative costs of consumptive material；Another party
Face uses and mechanically strikes even if existing dust catcher is equipped with extra large pa self-cleaning function, and the electromagnetic relay structure used
Extra large pa is played, so that the dust on extra large pa surface is shaken off into dust bucket, this debris removal mode clears up the dust on extra large pa surface
It is not thorough, product structure is more complex, and higher operating costs.
For this purpose, our company develops a kind of self-cleaning dust catcher, two air ducts and two motors are used, extra large pa one is divided
It is two, two motors work at the same time, so that the extra large pa of half is when positive exhausting filters dust, the other half extra large pa is then carried out instead
To dust-removing, this just needs to use the motor base for installing motor and being oriented to air-flow, and existing motor bottom
Seat, one side volume is too fat to move, structure is complicated, and on the other hand, the integrated and guiding in air duct is complicated, so that air duct is in handoff procedure
