The blackboard brush of dirt.
The content of the invention
It is an object of the invention to solve above-mentioned technical problem, there is provided a kind of dustproof blackboard brush, is closed by structure after improvement
Reason, suitable size, it is easy to use suitable for large-scale promotion the features such as, the automation of blackboard wiping is realized by electric rotary,
Improve work efficiency, and chalk dust is collected with the principle of pressure difference, greatly reduce chalk dust to educator and student
Harm.
In order to solve the above technical problems, present invention employs a kind of dustproof blackboard brush, including brush body, transmission mechanism, control
System and box body, wherein, the box body is the upper and lower structures being made of upper strata box body and lower floor's box body, the upper strata box body and
Partition plate is equipped between the tiltedly layer box body, power storehouse and dust passage is equipped with the cassette body, is equipped with the power storehouse
Power supply, the box body are equipped with switch, and the air inlet of the dust passage is equipped with fan, and the exit of the dust passage is set
There is disposal box, the disposal box is located at the outside of the box body and therebetween detachable connection；The transmission mechanism is arranged on
In the lower cassette body, the traditional mechanism includes two gear wheels, and a pinion gear and a motor, the pinion gear pass through electricity
Arbor is connected with motor, pinion gear perpendicular to the gear wheel circle center line connecting point midway for being positioned over two coplanar placements, and
It is meshed with two gear wheels；The brush body includes axis and hairbrush, and the hairbrush is arranged on the lower end of the axis, the axis
Upper end is connected with the gear wheel；Lower floor's box body includes bottom plate, and the transmission mechanism drives the brush body to rotate, the bottom
Upwardly extended in the middle part of plate equipped with dust absorption passage, the dust absorption passage is penetrated through with the dust passage.
Further, in above-mentioned technical proposal, the transmission mechanism is symmetrically arranged two sets.
Further, in above-mentioned technical proposal, the control system includes conducting wire, by conducting wire fan, power supply, switch
Link together with motor, energized by power supply, whole system is controlled by switching.
Beneficial effect possessed by the present invention：The present invention is rational in infrastructure, is of moderate size, and being rotated by motor realizes wiping
The automation of blackboard, improves work efficiency；Box body of the present invention is divided into two layers up and down, and ash has been obstructed using partition plate and lower floor's bottom plate
Dirt enters motor and gear engagement place, ensure that the normal work of motor and gear, improves the service life of blackboard brush, two sets
Transmission system is placed side by side so that brush body is also placed side by side, and this also increases erasing area；Switch is positioned at upper strata box body
Side, facilitates operation of the user to blackboard brush；The present invention is equipped with aspirating unit between upper strata box body and lower floor's box body, inhales
Lower floor's box body is run through in air flue lower end, and upper end is located at upper strata box body apoplexy fan flabellum and goes out, by the rotation aspirating unit of fan
Side pressure is less than by force lower end pressure, so that the dust under wiping is drawn onto in storage box, realizes dust-proof and dust-absorbing function, reduces
Harm of the dust to people, use of the invention are also convenient for, are adapted to promote the use of.
