As shown in figure 3, a kind of sweeper, which has above-mentioned dust-extraction unit, including installing wind on the car body
Machine 8 and expansion chamber 12,12 one end of expansion chamber upside are provided with dustbin 3, and 12 other end of expansion chamber is provided with described
Dirt pocket 10, the dust-extraction unit are mounted in the dirt pocket 10 and about 10 dirt pocket are divided into 115 sum aggregate of air-purifying chamber
Grey room 101, the side of the air-purifying chamber 115 are provided with cabinet air duct 7, and the dustbin 3 is set close to described 7 one end of cabinet air duct
It is equipped with air-out chamber 5, filter screen 4 is provided in the air-out chamber 5,7 both ends of cabinet air duct are respectively communicated with 5 He of air-out chamber
The air inlet of blower 8, the cabinet air duct 7 are also connected to the air-purifying chamber 115, i.e., the described cabinet air duct 7 passes through connection air-purifying chamber
Air-purifying chamber 115 described in outlet on 115, the cabinet air duct 7 and the connection of the air-purifying chamber 115 and air-out chamber 5 are punished
It is not provided with valve system 6；Valve system 6 can be using pneumatic operated valve after solenoid valve, motor-driven valve etc.；5 lower part of air-out chamber is also
It is connected to 12 top of expansion chamber；The expansion chamber 12 is connected to the dust collection chamber 101, i.e., the described expansion chamber 12 passes through connected set ash
Dust collection chamber 101 described in inlet communication on room 101；The dustbin 3 is communicated with suction tube 2, and the suction tube 2 is communicated with nozzle body 1,
Wherein the outer surface of suction tube 2 and the junction of expansion chamber 12,3 bottom surface of dustbin need to be fully welded, it is ensured that sealing performance；The nozzle body
1 lower end is rubbish inlet port, and upper end is connect with suction tube 2；It is located in the expansion chamber 12 and is connected to the dust collection chamber 101 and institute
It states and is disposed with several partitions 11 between air-out chamber 5.The suction tube 2 passes through the expansion chamber 12 and protrudes into the dustbin 3
It is interior；The air outlet of blower 8 connects exhaust pipe 9.
When work, under control of the control system, nozzle body 1 is dropped on road surface by the elevating mechanism of sweeper, together
Shi Fengji 8 rotates under the drive for cleaning car engine, and air in dustbin 3 is extracted out and is discharged in atmosphere, gas in case is caused
Body pressure reduction, forms pressure difference between atmosphere, thus make air constantly pass through nozzle body 1, suction tube 2 flow into dustbin 3 in.
Rubbish in this way on road surface passes sequentially through nozzle body 1 under the drive of air-flow, suction tube 2 enters in dustbin 3；Due to gravity
Effect, wherein heavier rubbish drops in dustbin 3, remaining rubbish is flowed with air-flow, larger when by filter screen 4
Rubbish be blocked and stay in dustbin 3, smaller, lighter rubbish is flowed out with air-flow through air-out chamber 5.Wherein such as solid line in Fig. 3
Shown in lines arrow, it is connected to when the cabinet air duct 7 is opened with the 115 connectivity part valve system 6 of air-purifying chamber with air-out chamber 5
Locate valve system 6 close when, air-flow can only entering in expansion chamber 12 by 5 lower part of air-out chamber, since space becomes larger suddenly,
Gas flow rate can decline, and dust drops to 12 bottom of expansion chamber under gravity；Simultaneously because expansion chamber 12 be equipped with every
Plate 11, therefore air-flow must be flowed according to designed channel, partition 11 can constantly be struck when flowing to and changing, due to hitting
The effect hit can also make a part of dust drop to 12 bottom of expansion chamber；Remaining smaller, lighter dust passes through sedimentation with air-flow
The outlet of room 12 enters the dust collection chamber 101 of dirt pocket 10, and under 102 filtration of filter cylinder of dust-extraction unit, dust stays in collection
In grey room 101, air-flow enters air-purifying chamber 115 and enters through cabinet air duct 7 and 115 connectivity part valve system 6 of air-purifying chamber after dedusting
In cabinet air duct 7, then air-flow is discharged in atmosphere again by blower 8 and exhaust pipe 9.And such as dashed lines arrow institute in Fig. 3
Show, fills when the cabinet air duct 7 is closed with the 115 connectivity part valve system 6 of air-purifying chamber and with 5 connectivity part gate of air-out chamber
When setting 6 opening, air-flow is no longer pass through expansion chamber 12 and dust-extraction unit, can only be entered in cabinet air duct 7 by air-out chamber 5, so
Air-flow is discharged in atmosphere again by blower 8 and exhaust pipe 9 afterwards, realizes rainy day cleaning work.
It is each used in cylinder 110, vibrating motor 112, blower 8, impulse electromagnetic valve and valve system 6 in the utility model
The components such as kind valve class are controlled by control system, and power supply, gas source used by above-mentioned each component etc. is all made of cleaning
Vehicle power supply and gas source on vehicle.
The above descriptions are merely exemplary embodiments of the present utility model, the model being not intended to limit the utility model
It encloses.Any those skilled in the art, made equivalent change under the premise of not departing from the conceptions and principles of the utility model
Change and modify, should belong to the range of the utility model protection.
