For this purpose, the present invention provides a kind of anion electric dust-free black board erasers, and including hollow shell, the bottom of the shell
Portion's opening；
The two rows of motors being parallel to each other in the longitudinal direction, the left and right alignment of the two rows motor are provided in the shell；
Every row's motor includes cross direction profiles and spaced two motors；
Rotor front end at the top of each motor is provided with a circle hairbrush.
Wherein, there is the area that partly overlaps in the hairbrush being arranged on each motor and adjacent other the two upper hairbrush being arranged
Domain.
Wherein, the rotation direction of the rotor of two motors of arbitrary neighborhood is opposite.
Wherein, the hairbrush is exposed to the bottom of the shell.
Wherein, the bottom outside of the shell is additionally provided with a circle rubber pad.
Wherein, be provided with rechargeable lithium battery in the shell, the rechargeable lithium battery and motor are conductively connected, for for
Motor provides work electricity consumption.
Wherein, the front of the shell is additionally provided with a control switch, which is arranged in the motor and institute
It states in the connection line between the power supply output end of rechargeable lithium battery, for controlling the motor and the rechargeable lithium battery
Between be switched on or off.
Wherein, it is provided with a hollow square box right above two rows of motors, a wind is provided in the square box
Fan；
The bottom of the square box has opening, and the opening is located at the underface of fan；
The size for the opening that the square box bottom has is less than the size of the square box bottom surface；
The fan is the fan rotated counterclockwise.
Wherein, multiple ventilation openings are had at left and right sides of the shell, and filtering is provided on the inside of the ventilation opening
Net.
Wherein, the inner right side of the shell is additionally provided with an anion generator, and the anion generator is put

Space is connected with space where the motor where the anion generator.
By the above technical solution provided by the invention as it can be seen that compared with prior art, the present invention provides one kind bear from
Sub- electric dustless blackboard eraser can effectively wipe clean blackboard, and effectively weaken dust pollution, guarantee the body of teachers and students
Body health, is of great practical significance.
Detailed description of the invention
Fig. 1 is a kind of structure schematic diagram of anion electric dust-free black board eraser provided by the invention；
A kind of Fig. 2 anion electric dust-free black board eraser provided by the invention is observed from top to bottom after taking away cover top portion
When structure schematic diagram.
Specific embodiment
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawing with embodiment to this
Invention is described in further detail.
Referring to Fig. 1 to Fig. 2, the present invention provides a kind of anion electric dust-free black board erasers, including hollow shell 1, institute
State the bottom opening of shell 1；
The two rows of motors 2 being parallel to each other in the longitudinal direction, the left and right pair of the two rows motor 2 are provided in the shell 1
Together；
Every row's motor 2 includes cross direction profiles and spaced two motors 2；
The rotor front end at each 2 top of the motor is provided with a circle hairbrush 3.
In the present invention, in specific implementation, what the hairbrush 3 being arranged on each motor 2 was above arranged with adjacent other two
There is the region that partly overlaps in hairbrush 3.Therefore, the overlapping region of these hairbrush, it is bigger to the erasing dynamics of dust, it can be realized more
Good dust removing effects.
In the present invention, in specific implementation, the rotation direction of the rotor of two motors 2 of arbitrary neighborhood is on the contrary, for example, such as
Shown in Fig. 1, when the rotation direction of the rotor of upper left corner motor 2 is clockwise, the rotation of the rotor of the lower left corner and upper right corner motor 2
Direction be it is counterclockwise, the rotation direction of the rotor of lower right corner motor 2 is clockwise.It is therefore convenient to by the powder on blackboard
Dirt is wiped clean by hairbrush 3.
In the present invention, in specific implementation, the hairbrush 3 is exposed to the bottom of the shell 1, such as exposes shell 1
15 millimeters of bottom.
In specific implementation, the bottom outside of the shell 1 is additionally provided with a circle rubber pad, moves this on blackboard to facilitate
The blackboard eraser provided is provided.
In the present invention, in specific implementation, it is provided with rechargeable lithium battery 6 in the shell 1, the rechargeable lithium battery 6
It is conductively connected with motor 2, for providing work electricity consumption for motor 2.
In the present invention, in specific implementation, the surface of the two rows motor 2 is provided with a hollow square box 8, described
A fan 4 is provided in square box 8；
The bottom of the square box 8 has opening, and the opening is located at the underface of fan 4；
The size for the opening that 8 bottom of square box has is less than the size of 8 bottom surface of square box, therefore, when dust is by wind
When fan 4 is drawn into square box 8, it is not easy to trickle down and come out from square box 8.
In specific implementation, the fan 4 is the fan rotated counterclockwise, and the same scavenger fan of working principle can be effectively
The dust that hairbrush 3 on motor 2 that square box 8 issues is wiped, is drawn into inside square box in time.
It should be noted that the square box 8 is plastics square box, when work, is connected to inside shell 1, is being loaded with dust
When, people can dismantle it from shell 1, outwell dust.
In the present invention, in specific implementation, the left and right sides of the shell 1 has multiple ventilation openings, the ventilation
The inside of mouth is provided with filter screen, to avoid dust from shell 1 while guaranteeing that the air-flow of shell 1 can flow smoothly
Left and right sides evolution.
In the present invention, in specific implementation, the front of the shell 1 is additionally provided with a control switch 5, the control switch
5 are arranged in the connection line between the motor 2 and the power supply output end of the rechargeable lithium battery 6, described for controlling
Being switched on or off between motor 2 and the rechargeable lithium battery 6.The control switch 5 can for it is existing any one
Touch key switch is switched for example, by using the touch key of existing mobile power source.
It should be noted that pressing control switch 5 for the present invention, then motor 2 rotates, and band electric brush 3 rotates, thus
The writing on blackboard is wiped, the fan 4 of 2 top of motor rotates, dust is sucked in square box 8.
In the present invention, in specific implementation, the right side of the shell 1 is additionally provided with charge port 9, when leaving unused, can be inserted in
On socket, charge to rechargeable lithium battery 6.
In the present invention, in specific implementation, the inner right side of the shell 1 is additionally provided with an anion generator 7, institute
It states and is equipped with protective cover outside the spray point of anion generator 7；
The 7 place space of anion generator is connected with the 2 place space of motor.
It should be noted that the protective cover is protective cover using plastic production, with mesh, to ensure air stream
Dynamic and blocks dust.Anion generator 7 can use existing small-sized anion generator, herein with prior art class
Seemingly, it is not unfolded to describe.
It should be noted that band is being just in air for anion that anion generator 7 is generated using its spray point and floating
The dust of charge is neutralized, and makes adsorbing powder dust, natural subsidence, so as to improve the environment at dais, the anion generated is to people
Body health also plays the role of positive.
Compared with prior art, the present invention has advantageous effects below:
1, using four motor driven hairbrush, it is ensured that clean chalk writing.
2, the present invention can simultaneously efficiently can get up dust collection while the chalk writing on cleaning off a blackboard.
