Abstract
The utility model relates to an automatic blackboard brush, which is characterized in that the automatic blackboard brush is composed of a circuit part and a mechanical part; the circuit part is to connect a positive-negative switcher (6) into a circuit; a power supply and a motor (1) are connected with each other through lead wires; the mechanical part is composed of a gear (2), tooth slices (3), a dust-absorbent blackboard brush (5) and a blackboard (4); the gear (2) is encircled on the motor shaft and linked up with the tooth slices (3); the dust-absorbent blackboard brush (5) is fixed on two tooth slices (3) and closely attached to the blackboard (4). The utility model can automatically wipe out the dirt on the blackboard and eliminate the trouble caused by blackboard cleaning, which can well absorb the chalk dust and avoid air pollution caused by chalk dust.
Description
Technical field
The utility model relates to a kind of blackboard brush, is a kind of full-automatic blackboard brush specifically.
Technical background
At present, in each large, medium and small, the blackboard educational aid that is absolutely necessary, blackboard all needs the people to wipe, the people who erases the board through regular meeting make hair, be chalk dust entirely on one's body, polluting the air in the classroom, threatening that the student's is healthy.The utility model provides a kind of automatic blackboard cleaning device, and it wipes the dirt on the blackboard automatically, and that has gone less to erase the board bothers, and can well absorb chalk dust, has avoided the pollution of chalk dust to air.
Summary of the invention
The purpose of this utility model provides a kind of full-automatic blackboard brush.
The technical solution of the utility model is: a kind of full-automatic blackboard brush, it is characterized in that it is made of circuit part and mechanical part, and described circuit part is to insert positive and negative switch (6) in the line, with wire connecting power and motor (1); Described mechanical part is made up of gear (2), gear piece (3), dust-absorbing blackboard brush (5) and blackboard (4), and gear (2) is located on the motor shaft, is connected with gear piece (3), and dust-absorbing blackboard brush (5) is fixed on two gear pieces (3), is close to blackboard (4).
The beneficial effects of the utility model are: adopt automatic control circuit, wipe the dirt on the blackboard automatically, that has gone less to erase the board bothers, and can well absorb chalk dust, has avoided the pollution of chalk dust to air.
Description of drawings
Below in conjunction with description of drawings and embodiment further to the utility model explanation
Fig. 1 is the utility model front view
Fig. 2 is the utility model gear cutaway view
Wherein 1-motor, 2-gear, 3-gear piece, 4-blackboard, 5-dust-absorbing blackboard brush, the positive and negative switch of 6-.
The specific embodiment
In Fig. 1, embodiment shown in Figure 2, a kind of full-automatic blackboard brush, it is characterized in that it is made of circuit part and mechanical part, described circuit part is to insert positive and negative switch (6) in the line, the direction of switch current, thereby the direction of rotation of control motor (1) is with wire connecting power and motor (1); Described mechanical part is by gear (2), gear piece (3), dust-absorbing blackboard brush (5) and blackboard (4) are formed, gear (2) is located on the motor shaft, be connected with gear piece (3), dust-absorbing blackboard brush (5) is fixed on two gear pieces (3), be close to blackboard (4), after the power supply energising, motor (1) begins rotation, drive gear (2) rotation on the motor shaft, the utilization positive and negative switch of electric current (6) makes the positive and negative rotation of gear, the positive and negative rotation of gear moves up and down gear piece (3), makes dust-absorbing blackboard brush (5) move up and down on blackboard (4), just the dirt on the blackboard (4) can be brushed, dust-absorbing blackboard brush (5) is to constitute with the high adsorption material, adsorbed chalk dust, reduced the low-priced of chalk dust everywhere and fly, avoided the pollution of chalk dust air.
