Description
Technical field
The present invention relates to cleaner field more particularly to a kind of double bag type dust collector bag dust filters.
Background technique
The working principle of dust catcher is motor of dust collector high speed rotation, sucks air from suction inlet, generates dirt case certain
Vacuum, dust enters the bag dust filter in dirt case by scrubbing brush, adapter tube, handle, hose, main suction pipe, and dust is left on bag dust filter
Interior, filtered air enters motor using one layer of filter, and the air into motor is flowed out through motor, is arranged by air outlet
Out.
So-called filter bag refers to a kind of bag-shaped filter device, usually has an air inlet, enters from air inlet
It is the air-flow for being mingled with dust, air-flow flows out filter bag by filter bag surrounding, while dust is left in filter bag.The prior art
In, filter bag is made according to different filtering requirements of a variety of materials, such as the filter paper or filter cloth of homogenous material, also has multiple
Filter bag made of condensation material.Existing filter bag air permeability be all it is identical, for biggish dust catcher, such as United States Patent (USP)
Biggish filter bag can be used since its space is larger in this tub type dust catcher shown in US5548868, will not generate tight
The problem of dust blocking of weight.But for the dust catcher of small volume, the small volume of dust catcher collecting vessel can only be used smaller
Filter bag, filter bag short especially for shape and long is easily blocked in suction when filtering the dust and sundries of larger particles
Around oral area.
The filter bag of dust catcher is mainly used to collect and filter the dust of dust catcher sucking, and fine dust can be trapped in filtering
The material surface of bag, with the increase for being detained amount of dust, the windage of filter bag material is also rising, after reaching to a certain degree, filtering
Bag cannot use, currently, filter bag haves the defects that following aspect: 1, arriving certain journey inside bag dust filter when debris accumulation
When spending, exhaust effect just be will be greatly reduced, because part is blocked, suction is just greatly reduced, under dust removing effects are serious
Drop；2, current bag dust filter is directly connected to motor, and in the running, bag dust filter can be adsorbed on motor motor, influences suction effect
Fruit；3, the expansion that the outer dimension of vacuum cleaner filter bag cannot be unlimited, mainly outer dimension be all according to dust catcher cavity come
Design, damaged or explosion, filter bag size are all just to be attached in chamber wall to filter bag when in use in order to prevent, utilize appearance
Cavity wall supports filter bag, prevent using when suction it is excessive, cause filter bag damaged or explosion.Size of filter bag is greater than cavity,
It just will appear filter material and fold accumulation.Air is difficult to pass through at accumulation, increases the crushing of filter bag instead.So cannot be to filtering
Bag is external to increase filter area.
CN201580026544.8 discloses a kind of vacuum cleaner filter bag for vertical type dust collector, the dust suction of the invention
Device filter bag has the length greater than width, leads to a long side and a narrow side.The vacuum cleaner filter bag is by two
Bag wall is formed, and the bag wall is circumferentially bonded together, so that forming inner space between two bag walls.Here, a bag
Wall has entrance, and air to be cleaned can enter vacuum cleaner filter bag by the entrance.It is filtered according to the dust catcher of the invention
Bag is characterized in that having in the longitudinally extending folding part of vacuum cleaner filter bag, as a result, in the bag wall for wherein introducing entrance
Bag wall has the elasticity of enhancing, and when filter bag is inserted into dust catcher, vacuum cleaner filter bag is unfolded when support plate folds,
It allows air to enter filter bag substantially unblockedly.
Patent No. CN201280024590.0 includes the vacuum cleaning apparatus of vacuum cleaner and filter bag, the invention
Filter bag is formed to have disposable, the flat non-woven fabrics filter bag of the first filtering bag wall and the second filtering bag wall, the filtering
Bag have at least one surface pleat, wherein each surface pleat include positioned at filtering bag wall surface region in region and in mistake
The region that protrudes and can be unfolded above the surface region of filter bag wall during vacuum cleaning, vacuum cleaner include tool
There is the filter bag reception space of rigid walls.
Above-mentioned two inventions, structure is complicated for bag dust filter, and vacuum cleaner is provided in filter bag, is only used for specifically inhaling
In dirt device.
In conclusion it is this field inventor urgent problem to be solved that it is low, which to solve filter bag utilization efficiency,.
Summary of the invention
It is an object of the invention to overcome problem above of the existing technology, a kind of double bag type dust collector dust filterings are provided
