Description
Technical field
The present invention relates to field of household appliances, more particularly to a kind of gas and dust separating device and dust catcher.
Background technology
Dust catcher is rotated at a high speed using motor band movable vane piece, and air negative pressure is produced in the housing of sealing, draws dirt
A kind of small domestic appliance of bits, motor of dust collector rotate at a high speed, suck air from suction inlet, dirt case is produced certain vacuum,
The bag dust filter that dust is entered in dirt case by scrubbing brush, adapter, handle, flexible pipe, main suction pipe, dust are left in bag dust filter, are filtered
Air afterwards enters motor by one layer of filter again, and this layer of filter is one of guarantor for preventing dirt bag rupture dust suction motor
Barrier is protected, interior is discharged into again after filtered air enters motor.
Therefore, the filtration in dirt case determines the pick-up performance and air permeability of dust catcher, if the filtering knot in dirt case
Structure excessively letter is dredged, and the air in suction dirt case is returned to interior with substantial amounts of dirt body, is mingled with the air of dirt body by electricity
It is not only limited to cooling effect caused by motor during machine, and easily motor is caused to block and damage motor, it is more serious
It is to be mingled with the bacterium grown close to the dust of earth's surface to be discharged into interior by dust catcher, greatly reduces the air ambient of interior,
The respiratory health of people is influenceed, has seriously run counter to the original intention of dust catcher clean air；If just to strengthen filtering dust
Effect, and set up the filter for influenceing air circulation, then as substantial amounts of dust accretions are on filter, dust is to filter
Cause to block, then can largely effect on the air permeability of dust catcher, cause air-flow to be difficult to be passed to outside dust catcher through motor, on the one hand subtract
The weak driving force of dust suction, is on the other hand reduced to cooling effect caused by motor, reduce motor benefits from the life-span.
Although dust catcher of the prior art has the setting cyclonic filter structure in dirt case, but by filter filtering
The larger thick dirt of particle rotates in dirt case all the time, and with the growth of usage time, thick dirt blocks filter bores, influences filter
Strainability, except this, the filter in vacuum cleaner dust case on the market is centrally-disposed, and dust leg is arranged on edge
Position, dust leg cause obstruction to the cyclone type rotation of air-flow in dirt case, not only cause unnecessary energy waste, also produce
Raw very big noise pollution.
Vacuum cleaner dust case of the prior art also has the defects of one very big, i.e., dirt case is difficult to clean, all on the market
Vacuum cleaner dust case is all to carry enclosed area, and except being decomposed using extracting tool to dirt case, user is difficult in dirt case
Portion's structure is cleaned, once dust has been accumulated in the closing dead band in dirt case, it will the air quality of dirt case discharge caused not
Good influence, the cleaning of current vacuum cleaner dust case are the problems of a generally existing and urgent need to resolve.
The content of the invention
For overcome the deficiencies in the prior art, the purpose of the present invention is：A kind of gas and dust separating device and dust catcher are provided, used
Interior cup sidewall opening gets rid of the structure of dirt, effectively prevents blocking of the thick dirt to filter bores, and uses multistage cyclone filtration, high
Effect is separated by filtration the thin dirt carried secretly in air-flow；Dust funnel using being arranged concentrically with filter grid, realizes air-flow breakthroughly
Accessible high-speed silent rotation；Gas and dust separating device is integrally used without dead space arrangements, solves hygiene problem.

As seen from Figure 11, the second whirlwind component 6 includes cyclone plate 61 and air gathering plate 62, is assembling the whirlwind
When plate 61 and air gathering plate 62, the cotton layer 8 of sandwiched one, the cotton layer 8 are provided with several cotton holes 81, the cyclone plate therebetween
61 extend downwardly from tornadotron 611, and the upper end edge of the tornadotron 611 is the perforate edge of cyclone plate 61, the tornadotron
611 are corresponded with the dust-leaking hole 52, and the lower end of the tornadotron 611 is docked with dust-leaking hole 52, in order to facilitate cyclone plate 61
With the fixation of the deflector 5, one or more montants, correspondingly, the cyclone plate are provided with the upper surface of the deflector 5
61 are provided with the fixing hole coordinated with the montant, when the lower end of the tornadotron 611 is docked with dust-leaking hole 52, the montant
Insert in corresponding fixing hole, the fixation of deflector 5 and cyclone plate 61 is realized using screw；Offered on each tornadotron 611
Whirlwind enters hole 612, and the air gathering plate 62 extends downwardly from duct set 621, and the upper end edge of the duct set 621 is air gathering plate 62
Perforate edge, the duct set 621 corresponds with the cotton hole 81, the shapes and sizes in the cotton hole 81 and the collection wind
The shapes and sizes of the upper end of pipe 621 are consistent, and the lower end of duct set 621 is inserted in the tornadotron 611, the profit of air gathering plate 62
The upper end open for covering tornadotron 611 is sealed with cotton layer 8.
The upper lid 7 is arranged on the top of air gathering plate 62, and the upper lid 7 is provided with air outlet 71, and the air outlet 71 is with taking out
The entrance connection of jet power unit, as seen from Figure 2, offers the first air inlet 11, the interior cup in the side wall of outer cup 1
Offer the second air inlet 21 in 2 side wall, first air inlet 11, the second air inlet 21, filter element 3, pod apertures 51,
Whirlwind enters hole 612 and forms current path, and the current path connects to form air-flow branch with duct set 621, air outlet 71, described
Path connects to form dirt body branch with tornadotron 611, dust-leaking hole 52, dust leg 42.
In the dust catcher course of work, specifically flow direction is air-flow in gas and dust separating device of the invention：In pumping power dress
It is low-pressure state under the driving put, in the gas and dust separating device, the indoor air entrainment of dirt body is by the quilt of the first air inlet 11
Outer cup 1 is sucked, then into interior cup 2, specifically, the region in the interior side wall of cup 2 close to top is provided with opening 22, excellent
The upper end edge of cup 2 opens up breach including electing as, so, including air-flow during the internal rotation of cup 2, the dirt bodies of larger particles just from
The opening 22 throws away and fallen into outer cup 1, and then cyclonic air flow enters wind-guiding by the filter bores 31 of filter element 3 and led to
Road, then enter hole 612 by pod apertures 51 and whirlwind and enter in tornadotron 611, the whirlwind, which enters hole 612 and is preferably provided in, to be leaned on
The upper end of the nearly tornadotron 611, because duct set 621 is inserted in the tornadotron 611, the length of the duct set 621 is small
In the length of tornadotron 611, so, side wall of the air-flow along tornadotron 61 is rotated down, because the density of gas is less than dirt body
Density, therefore in the cyclone centrifugal rotation process of every one-level, air-flow up moves, and dirt body down moves, and is attained by gas
The effect of dirt separation, especially after the filtering of multiple tornadotron internal cyclones, gas reaches the lower end edge of duct set 621, meeting
Produce the remarkable result of gas dirt separation：Spoiler is provided with duct set 621, prevents air-flow from being rotated in duct set 621, gas
The duct set 621 is risen up into a low voltage state, is finally discharged from the air outlet 71 of upper lid 7, the cleaned air after then filtering
Discharged from the gas and dust separating device, enter in pumping power set and motor is cooled, be ultimately discharged into interior, i.e.,
The gas of interior is purified；And the weight of dust is far longer than the weight of air, because air-flow stops rotation in duct set 621
Turn, thus dirt body can not follow air-flow rise and drop downwards, dirt body effectively by the dust-leaking hole 52 of the bottom of tornadotron 611 and
Enter in dust leg 42.In order to strengthen the effect of cyclonic filter in interior cup, second air inlet 21 is arranged on interior cup 2
Sidewall bottom.
