Description

A kind of air duct apparatus for fast switching for extra large pa self-cleaning dust catcher

Technical field

The utility model relates to cleaner field, in particular to a kind of air duct for extra large pa self-cleaning dust catcher is quick Switching device.

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 air duct apparatus for fast switching, with the negative pressure and air-flow progress for generating two motors Guiding and alternately switch, two halves sea pa is enabled to be alternately carried out dedusting and filtering, and existing air duct apparatus for fast switching There are the following problems: firstly, volume is too fat to move, structure is complicated；Again, the integrated and guiding in air duct is complicated, so that air duct exists Handoff procedure apoplexy can be lost excessive, lead to that noise is big, wind-force is small；Finally, there are stagnant for the switching reciprocal back and forth in air duct Property afterwards, leads to occur in actual use that low-response, Operational Figure Of Merit are low, reduces the usage experience of operator.

In view of this, being used it is really necessary to develop a kind of air duct apparatus for fast switching for extra large pa self-cleaning dust catcher To solve the above problems.
