Abstract
The utility model discloses a novel electric dust removing blackboard eraser which is composed of a motor part (1), a fixed bearing (2), an upper chain gear (3), a rotating shaft (4), an upper chain (5), a lower chain (5), a fixed slide slot (6), a slide wheel (7), a lower chain gear (8), a brush eraser (9) and a dust receiving box (10). The utility model is characterized in that the motor part (1) forms up-down rotation, the brush eraser (9) is driven by the upper chain (5) and the lower chain (5) through the upper chain gear (3) and the lower chain gear (8) to up and down rub to remove chalk writing on a whole blackboard. Chalk dust is centralized and processed by the dust receiving box (10), which is time-saving and labor-saving.
Description
The utility model relates to a kind of electrical dust-removing blackboard eraser.
The blackboard eraser of people's use at present mostly is the mane blackboard eraser of hand-held, and the shortcoming of this blackboard eraser is to use effort, and dust from flying is unhygienic.
The purpose of this utility model just provides a kind of electrical dust-removing blackboard eraser laborsaving, health that uses.
The purpose of this utility model is achieved in that motor part (1), rigid bearing (2), goes up chain pitch wheel (3), coaxial being installed together of turning cylinder (4), lower chain gear (8) is housed below the last chain pitch wheel (3), on last chain pitch wheel (3) and the lower chain gear (8) lower chain (5) is housed, hairbrush eraser (9) is housed on the last lower chain (5), dirt-collecting box (10) is housed below the hairbrush eraser (9).Motor part (1) is rotated (reversible electric machine can positive and negatively rotate) after connecting power supply, and chain pitch wheel drives in (3) rotates, thus drive go up lower chain (5) upwards (or downward) mobile.Last lower chain (5) drive again hairbrush eraser (9) upwards (or downwards) move, this system is contained on the blackboard, promptly reach the electronic purpose that erases the board because the dust under wiping drops in the following dirt-collecting box, do not contact with staff.Thereby realized goal of the invention laborsaving, health.
The utility model is compared without manpower with the hand-held blackboard eraser of present usefulness and is erased the board, and has improved the speed that erases the board, and user's hand, clothes can not made dirty.
Below in conjunction with drawings and Examples the utility model is described further.
It shown in the accompanying drawing a kind of structural principle schematic diagram of the present utility model.Among the figure: 1-motor part 2-rigid bearing 3-goes up chain pitch wheel 4-turning cylinder
The last lower chain 6-of 5-is sliding tray 7-movable pulley fixedly
8-lower chain gear 9-hairbrush eraser 10-dirt-collecting box
Shown in the accompanying drawing a kind of specific embodiment of the present utility model: motor part (1) and two rigid bearings (2), go up chain pitch wheel (3) for two, be installed together by turning cylinder (4), below two last chain pitch wheels (3) two lower chain gears (8) are housed, go up for two two upward lower chains (5) are housed on chain pitch wheel (3) and the lower chain gear (8), article two, go up on the lower chain (5) hairbrush eraser (9) is housed, dirt-collecting box (10) is housed below the hairbrush eraser (9), movable pulley (7) is equipped with at the two ends of hairbrush eraser (9), article two, two sliding trays (6) are equipped with in the outside of going up lower chain (5), and two movable pulleies (7) slide up and down along two sliding trays (6).Motor part (1) is used reversible electric machine earlier, but both forward and reverse directions rotates.
Claims (2)
