Description
Technical field
The present invention relates to small household appliances field, in particular to a kind of air duct for extra large pa self-cleaning dust catcher is switched fast
Structure.
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 motor are used, by extra large pa one
Be divided into two, two motor work at the same time so that the extra large pa of half positive exhausting filter dust when, the other half extra large pa then into
The reversed dust-removing of row, and existing air duct switching construction, one side volume is too fat to move, structure is complicated, on the other hand, so that air duct exists
Handoff procedure apoplexy can be lost excessive, lead to that noise is big, wind-force is small.In view of this, being used for it is really necessary to develop one kind
The air duct quick switching structure of extra large pa self-cleaning dust catcher, to solve the above problems.
Summary of the invention
For the shortcomings of the prior art, the object of the present invention is to provide one kind to inhale for extra large pa self-cleaning
The air duct quick switching structure of dirt device, while improving structural compactness, reducing structural volume and complexity, additionally it is possible to drop

Between the right mounting groove 1352b of 1351b and second.
Working principle：
Referring to Fig. 2, the air-flow in left diversion air duct 1312 is flowed along the direction arrow A, the air-flow in right diversion air duct 1322
Along the direction arrow B flow, left wind deflector 181 and right wind deflector 182 when being not affected by air-flow impetus, in freely it is sagging it
Gesture, and the same time only allows the air-flow flowing in the flowing of the air-flow in left diversion air duct 1312 or right diversion air duct 1322,
Referring to Fig. 3, the air duct end of left diversion air duct 1312 is respectively equipped with left front limit plate 1354 and left back limit plate 1356, and a left side is kept out the wind
When naturally drooping, the trend rotated to the left is limited plate 181 by left front limit plate 1354 and left back limit plate 1356；It leads on the right side
The air duct end in stream air duct 1322 is respectively equipped with right front limit plate 1355 and right rear position margining plate 1357, and right wind deflector 182 is in nature
When sagging, dextrorotary trend is limited by right front limit plate 1355 and right rear position margining plate 1357.
It is further described so that right diversion air duct 1322 is connected with manifold port 1353 as an example.Referring to Fig. 3, left diversion air duct
1312 flow without air-flow, and left wind deflector 181 is in the gesture naturally drooped, and the air-flow of right diversion air duct 1322 is flowed along the direction arrow B
Dynamic, right shell body 182 is pushed to horizontality by the air-flow of right diversion air duct 1322, and left wind deflector 181 is because it is rotated to the left
Trend limited by left front limit plate 1354 and left back limit plate 1356 so that left diversion air duct 1312 is by left wind deflector 181
It is blocked, the air-flow for flowing into air duct switching channel 135 is stopped by left wind deflector 181, can only flow into manifold port 1353.It leads on a left side
The principle that stream air duct 1312 is connected with manifold port 1353 is similar to the above, and details are not described herein.
Number of devices and treatment scale described herein are for simplifying explanation of the invention.To application of the invention,
Modifications and variations will be readily apparent to persons skilled in the art.
