Abstract
The utility model discloses a blackboard eraser with a minitype dust absorption function, aims at solving the technical problem of flying of dust when the blackboard eraser is used, mainly comprises eraser hairs, a shell, a dust absorption plate, a clapboard, a dust storage bag, an air vent, fan blades, a motor, a battery case and a switch, and is characterized in that the motor with the fan blades is arranged in the blackboard eraser; the air vent, the battery case and the switch are arranged at the bottom of the blackboard eraser, namely below the motor; the dust absorption plate is arranged at the position of the eraser hairs and is connected with the shell and the clapboard; and the motor is communicated with a space formed by the motor, the dust absorption plate and the clapboard so as to form a complete dust absorption channel, so that dust absorbed on the dust absorption plate can be absorbed in and transferred to the dust storage bag designed in the clapboard. By adopting the scheme, the blackboard eraser can achieve the aim of collecting the dust of chalks and preventing the dust from flying, and can effectively prevents the health of teachers and students from being influenced due to sucking in the dust of the chalks.
Description
Technical field
The utility model relates to a kind of blackboard eraser, especially a kind of blackboard eraser with the small duster function.
Background technology
At present, when ordinary blackboard eraser erases the board, equal phenomenons that can cause powder to exist everywhere, this is having a strong impact on teachers and students' health, though some dust-proof blackboard erasers are also arranged, all because DeGrain or be inconvenient to use and do not popularized, problem is not well solved so far.
Summary of the invention
The purpose of this utility model provides a kind of blackboard eraser of band small duster function simple in structure.
A kind of blackboard eraser of the present utility model with the small duster function, its objective is to solve the technical problem that dust flies upward easily when using blackboard eraser everywhere, mainly form by blackboard eraser hair, shell, dust-catching board, dividing plate, storage dirt bag, ventilating opening, flabellum, motor, battery case and switch.It is characterized in that: in the blackboard eraser indoor design motor of being with flabellum is arranged, the motor below is that the bottom design of blackboard eraser has ventilating opening, battery case and switch; The dust-catching board design is connected with dividing plate with shell at blackboard eraser hair position; Motor communicates with dust-catching board and the formed space of dividing plate.
Beneficial effect: the motor that has designed the band flabellum in a kind of blackboard eraser technical scheme of the present utility model with the small duster function, can play the effect of Small-sized suction cleaner, the dust that can will be adsorbed on dust-catching board during use by the passage that dividing plate forms shifts and also temporarily is stored in the dirt bag, can reduce the dust pollution that causes because of erasing the board, more help the healthy of teachers and students.
