Abstract
The utility model discloses an electric dust collecting blackboard eraser mainly comprising a dust collecting box, a plurality of eraser plates, eraser cotton, a rotating shaft, a circular gear, an electric motor, a storage battery, a switch, a motor cover plate, a gear cover plate and a charging cable. The electric dust collecting blackboard eraser is characterized in that the dust collecting box is an uncovered box, four walls of which are inclined inwards; a bottom plate of the dust collecting box is uniformly provided with the plurality of circular eraser plates; the outer side of each eraser plate is fixedly provided with one of the circular eraser cotton with a proper size; and the rotating shaft, the circular gear, the eraser plates and the eraser cotton are driven by the electric motor to rapidly rotate, so that a blackboard can be well erased to be clean. The eraser cotton has very high elasticity, and the thickness of the eraser cotton is slightly larger than that of the dust collecting box; and when the blackboard is erased by pressing the blackboard eraser, the eraser cotton can be compressed to be as thick as the dust collecting box, and the four walls of the dust collecting box cling to the blackboard, so that the inside of the dust collecting box is in a sealed state, and chalk ash erased by the eraser cotton can only fall into the dust collecting box, but can not fly away.
Description
Technical field
The utility model relates to a kind of teaching aid, especially a kind of electric dust blackboard eraser.
Background technology
When existing blackboard eraser is used for the letter written with chalk on blackboard wiping, chalk dust all can fly upward all over the sky, make the person be above and on desk everywhere, extremely unhygienic, existing a kind of patent No. is 201220252206.X " black board eraser with chalk-dust collector ", because of its wiping board and to wipe cotton be a monoblock, be unfavorable for that chalk dust is scattering in dust-collecting box, the speed erased the board is slower, also wipes totally not, and effect is very undesirable.
Summary of the invention
The purpose of this utility model is to provide a kind of electric dust blackboard eraser, in dust-collecting box, is evenly distributed with the wiping board of a plurality of circles and wipes cotton, drives the cotton fast rotational of eraser board eraser with motor, can wipe clean fast blackboard, and chalk dust is flown upward everywhere.
The utility model is achieved through the following technical solutions: the utility model electric dust blackboard eraser, mainly comprise dust-collecting box, wipe cotton, wiping board, rotating shaft, circular gear, motor, battery, switch, motor cover plate, gear cover plate and charging wire, it is characterized in that: described dust-collecting box is an intilted uncovered box of wall, on the base plate of dust-collecting box, be evenly distributed with the wiping board of a plurality of circles, the outside of each wiping board is fixed with a sizable circular cotton of wiping, and inboard center is connected with a rotating shaft; Rotating shaft passes the circular hole on the dust-collecting box base plate, and every rotating shaft is fixed with a circular gear, and the teeth of the circular gear at center and circular gear are on every side agreed with mutually, and with a gear cover plate, all circular gears are covered.That root rotating shaft at center is longer, passes gear cover plate, connects a motor, and a chargeable battery is installed on the motor side, and a charging socket is arranged on battery; Between motor and battery, there is conductor wire to connect, and a switch is installed.Outside covers motor and battery with a dynamo-electric cover plate, and on dynamo-electric cover plate, there are two breach the position of respective switch and charging socket, and switch and charging socket can be exposed, and is convenient to push switch and charging.Configure in addition a charging wire with plug.Press switch, motor is started working, the cotton fast rotational of driven rotary axle, circular gear and eraser board eraser, thus can wipe clean well blackboard.Wipe the cotton extremely strong elasticity that has, its thickness is slightly above dust-collecting box, when pinning blackboard eraser and erasing the board, it is equally thick that the wiping cotton can be compressed to dust-collecting box, and the dust-collecting box wall is close to blackboard, makes in dust-collecting box to become sealing state, the chalk dust of wiping under cotton rub can only drop in dust-collecting box, and can not fly away away.
The utility model electric dust blackboard eraser, simple in structure, make simple and easyly, with low cost, be easy to promote.
The accompanying drawing explanation
Fig. 1 is organigram of the present utility model.
1-dust-collecting box wherein, 2-are wiped cotton, 3-wiping board, 4-rotating shaft, 5-circular gear, 6-motor, the dynamo-electric cover plate of 7-, 8-battery, 9-switch, 10-charging socket, 11-charging wire, 12-plug, 13-gear cover plate.
The specific embodiment
As shown in Figure 1, the utility model electric dust blackboard eraser, mainly comprise dust-collecting box (1), wipe cotton (2), wiping board (3), rotating shaft (4), circular gear (5), motor (6), charger (8), switch (9), the motor cover plate (7), gear cover plate (13) with charging wire (11), it is characterized in that: (1) described dust-collecting box is an intilted uncovered box of wall, on dust-collecting box base plate (1), be evenly distributed with the wiping board of a plurality of circles (3), (2) each wiping board outside (3) is fixed with a sizable circular wiping cotton, and (4) inboard center is connected with a rotating shaft; (4) rotating shaft passes the circular hole on the dust-collecting box base plate, the circular gear that (4) every rotating shaft is fixed with a circular gear ⑸， center (5) and the teeth (5) of circular gear on every side agree with mutually, and (13) (5) all circular gears are covered with a gear cover plate.
That root rotating shaft at center is (4) longer, passes gear cover plate (13), connects a motor (6), and (8) motor (6) side installs a chargeable battery, and (10) battery has a charging socket on (8); Motor (6) and battery have between (8) conductor wire to connect, and a switch is installed (9).(8) (6) (7) outside cover motor with battery with a dynamo-electric cover plate, and (9) (7) dynamo-electric cover plate goes up respective switch has two breach with charging socket position (10), and (10) (9) switch can be exposed with charging socket, is convenient to push switch (9) and charging.Configure in addition one with plug charging wire (12) (11).
During work, press switch (9), (6) motor starts working, and the driven rotary axle (4), (3) (5) circular gear wipe (2) fast rotational of cotton with wiping board, thereby can wipe clean well blackboard.
Wipe the cotton extremely strong elasticity that (2) has, its thickness slightly above dust-collecting box (1), while pinning the electric dust blackboard eraser, wiping cotton, (2) can be compressed to dust-collecting box (1) equally thick, and dust-collecting box (1) wall is close to blackboard, makes dust-collecting box become sealing state in (1), wipe cotton chalk dust under (2) wiping can only drop on dust-collecting box (1) in, and can not fly away away, because of dust-collecting box wall (1), slope inwardly again, so the chalk dust that dust-collecting box is collected in (1) can not poured out easily.During the cleaning chalk dust, as long as tremble the electric dust blackboard eraser passable downwards.
