Description
Technical field
The present invention relates to dust catcher, particularly relate to the filter of dust collecting bucket of dust catcher.
Background technology
Dust catcher is a kind of household electrical appliance of indoor cleaning health, is used for removing the dust in ground, carpet, wall, furniture and various slits.In general, dust catcher mainly comprises aspirator and suction line, with motor and blower fan is that the aspirator that dominant shape becomes is arranged in the body, suction line comprises suction nozzle and air intake duct, and the air entry of the oriented under shed of suction nozzle and telescoping tube and flexible pipe by air intake duct communicate with the air inlet of body inner blower.During the dust catcher running, the impeller of motor drives blower fan rotates at a high speed, and the air in the dust catcher is discharged, and forms instantaneous vacuum in dust catcher, and forms a quite high Negative Pressure Difference between the ambient atmosphere.Under the effect of this Negative Pressure Difference, near the dust the suction nozzle is drawn in the dust bucket in the body by air entry together with air.The air that contains dust after filtering, flows back to the dust catcher outside from air outlet again in the body dust bucket.Like this, just reach the effect of dust out, clean floor.The suction rate of dust catcher is divided into a plurality of class of operating control, adapts to the scope of operation of different cleaning objects such as ground, bed surface, sofa, corner, so that aspirate dust everywhere better.
For dust catcher, no matter be vertical type dust collector or horizontal dust collector, the dust bucket of assembling dust all is set in the dust catcher body, the dust and the foreign matter that gather in the dust bucket regularly remove again, to ensure the normal use of dust catcher.
Fig. 1 is the surface structure schematic diagram of a kind of dust collecting bucket of dust catcher of prior art.
As shown in Figure 1, it is cylindric that dust bucket is, and is made of staving 1, bung 2 and filter 3.Bung 2 is buckled on the staving 1, and filter 3 is set in the staving 1, and filter 3 is fixed on the bung 2 by fastener, and filter 3 is made of the filter core 8 of crossing of outer field screen pack 7 and internal layer.Bowl inner chamber is divided into two parts up and down by demixing plate 5, and top is provided with filter 3, and the lower part is provided with wind pipe 6.Filter 3 and wind pipe 6 are arranged on the middle part of bowl inner chamber, the both sides up and down of the demixing plate 5 that is placed in.One side of staving 1 has the handle 4 of upper and lower settings, is used for picking and placeing of the interior dust bucket of dust catcher body.Staving 1 up knob 4 relative opposite sides are provided with air inlet and air outlet, and air inlet is positioned at the top of staving 1, and air outlet is positioned at the bottom of staving 1 and is communicated with the wind pipe 6 of staving.
During the running of dust catcher blower fan, the air that has dust is drawn in the dust bucket through the air inlet of setovering, cyclone is formed at the top at bucket, the part dust drops to barrel outside of bottom wind pipe 6 along the slit, edge of demixing plate 5 in the process of air-flow rotation, simultaneously, the air of inspiration is discharged dust catcher from filter 3 bottoms through wind pipe 6 and air outlet after filtering through filter 3 again.
Fig. 2 is the filtration device structure exploded view of dust catcher.As shown in Figure 2, the filter of dust catcher is a cylinder-like structure, is made of the filter core 9 of crossing of outer field screen pack 7 and internal layer, is fixed on the bung 2 by fastener 8.The fastener 8 of screen pack 7 upper ends is stuck on the buckle of bung 2 inner faces setting, and filter core 9 was set in the screen pack 7, crosses filter core 9 and is made by sponge or ventilative fabric.
The filter of dust catcher is particularly crossed filter core, filters and gathers most of dust in the suction air.Dust is too many in the filter, can influence the suction rate of dust catcher.Therefore, dust catcher is dust out often, particularly removes the dust in the filter core, needs water to clean sometimes.But the dust remover filter of above-mentioned prior art, dust out are very inconvenient.At first to take off the bung of dust bucket from bucket, reverse fastener with the filtration rack of holding filter again and filter is taken off from bung, and then cross filter core with handgrip and from the screen pack of tubular, take out, one step of back just can be carried out screen pack and be cleaned with dust removing or the water of crossing filter core.This shows that the structure of dust collector of above-mentioned prior art makes dust out pretty troublesome, must directly remove to grab screen pack and cross filter core, can make the user make the full hand all to be dust with hand, very unhygienic.
Summary of the invention
Dust catcher at above-mentioned prior art, it is very inconvenient to open the filter dust out, must directly remove to grab screen pack and cross filter core with hand, existence can make the user make the full hand all to be dust and very antihygienic problem, the present invention releases the filter that opener is set on the end cap and appears end cap from the dust bucket bung, its objective is when needs are removed the dust of filter, can directly take out filter and cross filter core, avoid unhygienic ground directly to remove to grab the filter core of crossing dusty with hand from the dust bucket top.
Filter structure of vacuum cleaner involved in the present invention is made of with the screen pack with annular top the filter core of crossing that opener is set on the end cap, and filtration net cover is being crossed the filter core periphery.Cross the filter core end cap and link together, cross the outer annular edge of filter core end cap and the interior ring edge joint of screen pack annular top and lump together by opener and screen pack annular top.The outer annular edge of screen pack annular top is threaded with dust bucket bung mesopore inner edge.
Cross the sliding shoe that the opener that is provided with on the filter core end cap comprises band spring in the fixing rib that is arranged on the end cap, the fixing rib groove, and is connected with sliding shoe and can inserts the plug-in unit that encircles in the screen pack annular top in the jack of limit.Sliding shoe can longitudinal sliding motion in the fixing rib groove, and the plug-in unit that drive is connected with sliding shoe is flexible.There is arc groove in fixing rib two outsides.
For dust remover filter involved in the present invention, when needs are removed inner dust, need not open the bung of dust bucket, can in the mesopore of dust bucket bung top, directly take out filter.Concrete operations are: the arc groove and the rotational fixation rib that fasten rib two outsides earlier with finger buckle, then screen pack annular top outer annular edge is unclamped with being threaded of dust bucket bung mesopore inner edge, in the mesopore of dust bucket bung, take out filter again, like this, just can carry out the dust of the outside screen pack of filter easily removes and the water cleaning; Then, pin two sliding shoes in two grooves on the fixing rib again and it is moved in opposite directions to the center, two sliding shoes are oppressed adjacent separately spring respectively and are made the plug-in unit indentation that is connected with sliding shoe, then extract out in the jack on plug-in unit ring limit in the screen pack annular top of inserting, the outer annular edge of crossing the filter core end cap that is bonded together is separated with the interior ring limit of screen pack annular top, just can will cross filter core and from screen pack, take out, carry out the dust of filter core again and remove and the water cleaning by the finger of fastening fixing rib two outer arcuate grooves.
Filter structure of vacuum cleaner involved in the present invention has been realized removing the filter dust quickly and easily, avoids unhygienic ground directly to go to grab filter core, effect and the user's prestige of having promoted the dust catcher product crossed dusty with hand.
