Abstract

The cleaning device has a sealed box; sucking pipe and sucking port in the front lower part of the box; and blower and blowing pipe in front top part of the box. The blower pumps air from the box and blow wind through the blowing port inside the sucking port to the ground to raise dust inside the sucking port. The blower and the exhauster pump out air from the sealed box to produce negative pressure. Air is made up from the sucking port of produce sucking force so as to suck the dust raised by the blowing port into the box. Inside the box, there are dust filtering mesh and sawtooth dust filter to accumulate dust and other dirt in the box.

Description

Blowing and drawing type floor cleaning car cleaning device

The present invention relates to a kind of cleaning cart cleaning device of ground environment health, especially floor-dust can be received only, do not make dust raise out twice pollution.

At present, known cleaning floor is with the brush airborne dust, gathers dust.The method cleaning floor of sweeping, sweeping kicks up a dust does not receive, and the pocket dust can not swept, and the existing road cleaning cart is to gather dust by rotation brush and cylinder brush.No matter be with what brush method.Dust can only be kicked up.But the dust of kicking up all can't be collected and store, and just dust being kicked up goes other place.It is very few to collect dust, according to the dust characteristic.The one, the water flushing, the 2nd, air-blowing can be with the whole Ex-alls of floor-dust.

The present invention uses the air blowing airborne dust exactly.Air-breathing receipts are gathered dust, be in one in China: with the slightest effort, common saying inspire me to study, dust is blown afloat the absorption leicht fallen D/A, but can not blow afloat the ground ash, all inhale at big suction floor-dust unclean, as you know five, strong breeze is floor-dust, sand, foreign material are scraped to such an extent that exist everywhere, for according to tool with six, the air velocity amount of force 7 wind blows afloat the floor-dust foreign material in suction inlet, two blower fans go into to deflate from stuffing box, produce negative pressure in the case, replenish air from suction inlet, suction inlet produces suction, in the dust inlet box that mouthpiece is blown afloat, dust is stored in case by filter bar grid net and dirt catcher.Gathering dust with pressure-vaccum not only replaces history besom for a long time, and the speed of gathering dust is fast.Make simple structure, use power little.Floor-dust can be received clean.Solve contamination by dust, the harm people's health.

The object of the present invention is achieved like this, connect hair-dryer from the stuffing box front upper place, the mouthpiece pipe, mouthpiece, then middle below connects the suction inlet road before the stuffing box, suction inlet, mouthpiece passes the suction inlet road, and mouthpiece is contained in the suction inlet, and hair-dryer deflates in the stuffing box and passes through blowpipe, mouthpiece, blow in suction inlet and on the ground, kick up a dust in suction inlet, two blower fans deflate in stuffing box, produce negative pressure in the case, replenish air from suction inlet, suction inlet produces suction, in the dust inspiration case that blows afloat in suction inlet, the below is provided with filter bar grid net in the case, and the top was provided with the first sawtooth pattern dirt device during case was interior.The outer rear of stuffing box is provided with exhaust blower, and the exhaust blower mouth is provided with a bag type dirt catcher.Though air one in dust, the foreign material suction seal case is to two blower fan direction diffluences.Dust is run into filter bar grid net, dedusting, air continues to flow to the first saw type dirt catcher diffluence and passes through dirt catcher, hair-dryer after the air purification is blown the air extraction in the inlet box that kicks up a dust on the ground again in suction inlet, the dust foreign material are not cutoff with air in the inlet box, hair-dryer deflates and constantly circulates hair-dryer, dual-use like this.Because of suction inlet greater than mouthpiece, need to increase the suction inlet air mass flow.Establishing an exhaust blower in the stuffing box back upper place, has been this respect effect, one, and to be exhaust blower deflate in stuffing box discharge case is discharged outer how many air of case, replenish how many air outside suction inlet.Replenishing air effect outside suction inlet is that the dust that mouthpiece blows afloat in suction inlet is blown in case, pushing down the dust that blows afloat does not raise outside suction inlet, two, increase suction inlet suction, three, two blower fans deflate at Liang Chu and have reduced flow velocity in the dust inlet, four, two blower fans separately, hair-dryer institute exhaust air is not walked second bag of type dirt catcher, reduces the air mass flow of second bag of type dirt catcher, plays filter dirt effect.

Because adopt such scheme, the speed of gathering dust is fast, all receipts are clean with blowing the dust of kicking up on ground.The mechanism's power of gathering dust is little, uses the air blowing airborne dust, removes existing cleaning cart brush dust arrester installation, has reduced manufacturing cost, has simplified operational sequence.Solved existing cleaning cart airborne dust dust collection effect problem of poor.

Below in conjunction with accompanying drawing and the insight structural map of example:

Fig. 1 is of the present invention according to the automobile sequence, the summary constructional drawing;

Fig. 2 is the partial sectional view of pressure-vaccum structure;

Fig. 3 is the A-A sectional view of summary;

Fig. 4 is that C analyses and observe;

Fig. 5 is F; Analyse and observe

Fig. 6 is that D analyses and observe; Among the figure: 1, suction inlet 2, mouthpiece 3, suction inlet road 4, blowpipe road 5, hair-dryer 6, exhaust blower 7, stuffing box 8, the first saw type dirt catcher 9, the first filter dirt product support 10, filter bar grid net 11, second dirt catcher 12, second bag of type dirt catcher support 13, pressure-vaccum mouth lift assembly 14, sealed container door

Deflate in to hair-dryer (5) from case in the air flow case in Fig. 1 suction inlet by, mouthpiece pipeline (4) connects splay configuration mouthpiece (2) and blows on the ground in inhaling and kick up a dust, because of hair-dryer (5) exhaust blower (6) two blower fans deflate in case, produce negative pressure in the case and replenish air from suction inlet (1), the dust that suction inlet (1) and suction inlet road (3) generation suction blow afloat mouthpiece (2) is drawn into stuffing box interior (7) to hair-dryer (5) and row's machine (6) diffluence.Running into filter bar grid net (10) dedusting reduction air velocity slowly flows to the first saw type dirt catcher (9) and air is further extracted out the interior air of stuffing box (7) again to blow in suction inlet (1) by filtration hair-dryer (5) kicks up dirt in inlet box, exhaust blower (6) deflates in stuffing box (7) and by second bag of type dirt catcher (11) air is emitted outside the case, emits outer how many air of case and will replenish how many air in the export-oriented suction inlet of suction inlet and push down the dust that blows afloat and do not raise outside suction inlet.

Clear in order to represent, please see Figure 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6.
