Background

A vacuum cleaner is a cleaning tool with wide application. The working principle of the dust collector is that a motor is used for driving blades to rotate at a high speed, air negative pressure is generated in a sealed shell, and dust is sucked. Common vacuum cleaners are horizontal type, vertical type, handheld type and the like. The handheld dust collector is widely applied due to small size and convenient carrying and use.

Therefore, the utility model provides an adjustable dust blocking sheet structure of dust catcher, including the dirt cup, be provided with the whirlwind intake pipe in the dirt cup, the whirlwind intake pipe includes air inlet duct and exhaust passage, and the structure of exhaust passage is the arc, arranges along the circumference of air inlet duct, and the air current that has the particulate matter gets into the air inlet duct of whirlwind intake pipe, flows from the air outlet of exhaust passage, and air outlet department is provided with the dust blocking sheet, and the dust blocking sheet is rotatable installs in the whirlwind intake pipe, and the dust blocking sheet is arranged along the axial of air inlet duct, and dust blocking sheet one side is provided with the limiting plate.

Further, the air outlet is tangent to the air inlet duct.

Further, the ash blocking sheet comprises a rotating shaft part and a blade part, wherein the rotating shaft part is rotatably arranged on the air outlet channel, and the blade part is of a structure with the width gradually increased from one end of the rotating shaft part along the axial direction of the rotating shaft part.

Furthermore, the dust blocking sheet is made of plastic.

Further, the structure of limiting plate is L shape, and the limiting plate includes first stopper portion and second stopper portion, and first stopper portion arranges along the axial of air inlet duct, and the second stopper portion arranges along the radial of air inlet duct.

Furthermore, the dust cup is made of transparent materials.

The utility model provides a pair of adjustable ash blocking piece structure of dust catcher, dust catcher during operation, the air current that has the particulate matter gets into the air inlet duct of whirlwind intake pipe, flows from the air outlet of air-out duct, and the ash blocking piece light of plastics material, rotatable do not influence the motion of air current. When the dust collector stops working, the dust blocking sheet blocks reversely sucked particles under the limitation of the limiting plate, so that the particles cannot enter the air outlet channel and the air inlet channel and then fall into the dust cup. The dust cup is made of transparent material, so that the working condition of the dust collector can be observed conveniently.

The utility model provides a pair of adjustable dust blocking sheet structure of dust catcher, the rotatable installation in gas outlet department of dust blocking sheet does not influence under the rotatory condition of air current, prevents that the particulate matter from inhaling backward from the gas outlet.
