Abstract
The utility model relates to an electric dust cleaning brush. The inner part of a housing is provided with a micro motor with a power supply for supplying power and being started and stopped by a switch; a centrifugal impeller is arranged on an output shaft; a dust filter and a seal ring are arranged on a middle wind port of a dust collecting barn; the circumference of an erasing brush fixedly arranged at the lower part of the housing forms a ventilating gap communicated with the dust collecting barn. By using the principle of electric dust collection, the motor runs at high speed to drive the impeller to rotate so as to form vacuum wind sucking force; brushed and cleaned dust is blocked and gathered in the dust collecting barn by the dust filter through the ventilating gap and is poured out from a dust outlet. The utility model can not produce dust nuisance to pollute environment so as to achieve the goal of purifying air, and also the working condition of the motor is improved and dust collecting effect is enhanced.
Description
The utility model relates to the electric dust absorption instrument.
Electric dust sucting brush is useful on the wiping of classroom blackboard, also is useful on the dedusting of sofa, bed blanket, woolen dress etc., the blackboard eraser that generally adopts in the society is wiped word at present, and its no dust-absorbing function causes dust to fly upward everywhere, the severe contamination surrounding environment has influenced the healthy of teacher, student.Electric dust absorption blackboard eraser that has now come out and various suction tool, its pick-up performance is poor, and the dust that is inhaled into easily pollutes internal structure, all is subjected to its evil as motor, wind wheel, has influenced service life.
The purpose of this utility model is to overcome the defective of prior art and provides a kind of pick-up performance better, can isolate the electric dust sucting brush of dust pollution internal structure.
The purpose of this utility model is achieved by the following scheme: be provided with the micro machine that is opened and closed by power supply power supply, switch in each chamber of housing, receded disk impeller is housed on the motor shaft.The power of motor can be made power supply by two joint rechargeable batteries, and perhaps the transformation commutating voltage is 3～36 volts a external direct current power supply.Brushing is fixed on the housing below, and brushing and inner walls form the seam that ventilates, and it leads to dust compartment, and the dust compartment sidewall has individual dust mouth, the chock plug sealing.The air port is provided with dirt catcher and sealing ring in dust compartment and motor, the blade wheel chamber.The high speed rotation of motor drives suction impeller and rotates, air between impeller blade is outwards bloated by centrifugal force, wherein is formed centrally vacuum pressure reduction, forms air draught power, the dust that wiping is got off is inhaled into and is blocked in the dust compartment by dirt catcher and sealing ring, has avoided dust from flying.Brushing as with felt hair system brush felt woollen brush, be used for blackboard wiping, as with pig hair system hog hair brush, can be used for dedustings such as sofa, bed blanket, woolen dresses.
The utility model is compared with known technology, owing to structurally adopt rational dust filtration device, the dust accumulation that makes suction is in dust compartment, and the purpose that purifies air that reaches both free from environmental pollution has been improved the condition of work of motor again, improves pick-up performance.
Accompanying drawing 1 provides structural representation of the present utility model.
From accompanying drawing 1 as can be known, electric dust absorption is brushed with the housing (1) of a band handle (7), housing (1) is divided into a plurality of chambers, and power supply room (8), electric motor with vane wheel chamber (17), dust compartment (10) and air outlet (3), middle air port, air inlet (14), dust mouth are arranged.
The power supply (5) that is provided with in the power supply room (8) of handle (7) is two joint rechargeable batteries and the switch (4) that opens and closes motor, be electrically connected with motor, motor is located in the electric motor with vane wheel chamber (7), receded disk impeller (6) is housed on the output shaft, and its other end is bearing on the middle air port by sealing ring (16).
Dirt catcher is made up of cone shape woven wire (15) and dust filtration paper (13), and dust filtration paper (13) covers on outside the woven wire (15), is fixed on the middle edge, air port by trim ring (12).On the dust mouth on dust compartment (10) rear sidewall chock plug (9) is arranged.
Housing (1) below four drift angles are being screwed felt hair brushing (11), and this brushing (11) forms the seam that ventilates with housing (1) inwall all around, communicates with dust compartment (10) by air inlet (14).
During use, the impeller that runs up (6) of motor (2) is rotated, owing to be subjected to the influence of centrifugal force to produce air draught power, so the dust that brushing (11) wiping is got off just sews suction dust compartment (10) by ventilation, dirt catcher all accumulates in the dust compartment (10) dust, pour out by the dust mouth, and air is discharged through air outlet (3).
Claims (5)
1, a kind of electric dust sucting brush, be provided with the micro machine (2) that opens and closes by power supply (5) power supply, switch (4) in each chamber of housing (1), impeller (8) is housed on the motor shaft, brushing (11) is fixed on housing (1) below, form the seam that ventilates around the brushing (11) and between housing (1) inwall, the seam that ventilates leads to dust compartment (10), chock plug (9) is equipped with in dust mouth on the dust compartment sidewall, it is characterized in that being provided with dirt catcher and sealing ring (16) on the middle air port of dust compartment (10) and motor, blade wheel chamber (17).
2, electric dust sucting brush as claimed in claim 1 it is characterized in that described power supply (5) can be a rechargeable battery, or the transformation commutating voltage is 3～36 volts a external direct current power supply.
3, electric dust sucting brush as claimed in claim 1 is characterized in that described impeller (6) is a receded disk impeller.
4, electric dust sucting brush as claimed in claim 1 is characterized in that described brushing (11) can be felt woollen brush or hog hair brush.
5, electric dust sucting brush as claimed in claim 1, it is characterized in that described dirt catcher is made up of cone shape woven wire (15), dust filtration paper (13), dust filtration paper (13) covers on outside the woven wire (15), is fixed on the middle edge, air port of housing (1) by trim ring (12).
