Abstract
The utility model discloses a dust collection type blackboard eraser, and relates to the technical field of teaching aids. A dust collection sponge is arranged on the surface of a fixed cavity, and the rear end of the fixed cavity is connected with a dust collection box through a dust collection pipe. The dust collection box is fixed to a main shell, and a dust collection filter screen is arranged in the dust collection box. A switch is arranged at the upper portion of the main shell. A plurality of heat dissipation holes are formed in the side surface of the main shell. A charging jack is formed in one sides of the heat dissipation holes. The dust collection type blackboard eraser can overcome shortcomings in the prior art, erase a blackboard conveniently and improve the teaching environment for teachers better, and is reasonable and novel in physical design, convenient to use, small in size, low in manufacturing cost, excellent in dust collection effect and suitable for wide popularization.
Description
Technical field:
The utility model relates to a kind of ash-collecting blackboard eraser, belongs to teaching aid technical field.
Background technology:
At present; most schools also continue to use the teaching method that chalk is taught always; teacher is on removing blackboard during by the writing of chalk-writing; need to blackboard, carry out wiping with blackboard eraser; in wiping process; the dust of chalk flies upward everywhere, has polluted the air ambient in classroom, has affected the teachers and students' that erase the board health.In order to reduce the pollution level of dust, a lot of local rags that wet that adopt erase the board, but teacher is in teaching process, uses very inconvenient.
Therefore in order to improve teacher's teaching environment, there is on the market blackboard eraser miscellaneous, some blackboard eraser is that the material of wiping surface is improved, with expectation, reach the effect of dust suction, also having some blackboard erasers is to adopt the effect of being combined to reach dust suction with large-scale dust catcher, and the effect of the blackboard eraser dust suction of the former change wiping surface material is not very desirable, and although the blackboard eraser pick-up performance that the latter is combined with large-scale dust catcher is good, but expensive, and volume is large, uses very inconvenient.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of ash-collecting blackboard eraser.
Ash-collecting blackboard eraser of the present utility model, it comprises dust suction sponge, fixed cavity, sweep-up pipe, dust-absorbing box, main casing, switch, dust suction filter screen, louvre, charging jack, induced-draught fan, micromachine and battery, the surface of fixed cavity is provided with dust suction sponge, the rear end of fixed cavity is connected with dust-absorbing box by sweep-up pipe, dust-absorbing box is fixed on main casing, dust-absorbing box inside is provided with dust suction filter screen, the top of main casing is provided with switch, on the side of main casing, be provided with several louvres, a side of louvre is provided with charging jack.
As preferably, the inside of described main casing is provided with induced-draught fan, micromachine and battery, and one end of induced-draught fan is connected with one end of micromachine, and other one end of micromachine is connected with battery with switch respectively.
As preferably, described fixed cavity inside is cavity, and is provided with square groove on the surface of fixed cavity, is provided with several adsorption holes in square groove, and in square groove, inlays and be provided with dust suction sponge.
The beneficial effects of the utility model: it can overcome the drawback of prior art, reasonable in design is novel, easy to use, volume is little, and cost is low, and blackboard wiping is more convenient, and there is good pick-up performance, can better improve teacher's teaching environment, suitable for large-scale promotion.
