2. The regenerative chalk dust absorbing blackboard eraser as claimed in claim 1, wherein: and the bottom of the cavity shell is provided with a long magnetic strip.

Technical Field

The invention relates to the field of teaching stationery, in particular to a dust-absorbing and regenerating chalk blackboard eraser.

Background

The blackboard is an indispensable teaching aid in teaching links, and teaching knowledge can be taught by writing on the blackboard from primary schools, middle schools to universities and some training institutions, but the phenomena of dust flying and dust easily attached to the surface of the blackboard eraser to cause unclean blackboard erasing always exist in the blackboard erasing process.

Dust flies upward to hurt the health of teachers and students and influence the cleanness and sanitation of classrooms, and the blackboard is not cleaned cleanly, so that the students can not see clearly the written handwriting, and the teaching quality is indirectly influenced.

In order to solve the technical problems, the invention provides a regenerated chalk eraser which is named as a regenerated chalk eraser and is characterized by comprising a regenerated chalk eraser function device, wherein the function device is provided with a dust collector switch, a charger interface, a self-made chalk switch and a water injection hole, a rechargeable battery, a water injection water tank, a small dust collector, a self-made pen mold and a small heating machine are arranged in the function device, the rechargeable battery and the small dust collector are connected with a control end of a main body of the chalk eraser, and an outlet of the water injection water tank is connected with the mold, the small heating machine and a heat dissipation port. The disadvantage is that the dust collector is powered by a battery, and self-service cannot be realized; the chalk regeneration process is invisible and has poor controllability.

Disclosure of Invention

The invention aims to solve the problems, and provides a dust-collecting and chalk-regenerating blackboard eraser to solve the problems that a dust collector is not driven by a power supply and the chalk regenerating process is visual and controllable.

In order to achieve the purpose, the invention designs a hollow shell and a felt, wherein the hollow shell is of a transparent structure, a plurality of rollers, a dust collector, a hopper, a water injection pipe, a self-made chalk mold, a heater and a battery box are arranged inside the hollow shell, the rollers are arranged at the opening end of the hollow shell in parallel in a clearance way, the felt is fixedly arranged on the surface of the rollers, the dust collector is arranged at the central position in the cavity shell, a driving shaft of the dust collector is connected with the shafts of the rollers through a fixed shaft gear train and a driving belt, the periphery of the hopper surrounds the water injection pipe and is arranged below the dust collector, the self-made chalk mold is of an easily heat-conducting transparent structure, the periphery of the self-made chalk mold surrounds the heater, the battery box is connected with the heater through a closed circuit, and the valve of the water injection pipe, the switch of the heater, the outer cover of the battery box and the chalk outlet cover of the self-made chalk mold are all arranged on the periphery side of the cavity shell.

Furthermore, a long magnetic strip is arranged at the bottom of the cavity shell.

The dust-absorption and regeneration chalk blackboard eraser has the following beneficial effects:

1. when the blackboard eraser is used for erasing a blackboard, the rollers wrapped by the felt roll in the same direction, the transmission belt drives the ordinary gear train to drive the dust collector to rotate, so that the dust collection purpose is realized, an additional power supply is not required in the whole dust collection process, and the blackboard eraser is green and energy-saving.

2. The cavity shell and the self-made chalk mold are both of transparent structures, so that the holding direction of the blackboard eraser can be conveniently identified when the blackboard is erased, the chalk capacity in the self-made chalk mold can be conveniently observed, and when the self-made chalk mold is fully loaded, the heater switch is opened to heat dust, and the water injection pipe valve is opened to add water to generate new chalk.

3. The bottom of the cavity shell is provided with the long magnetic stripe, so that the blackboard eraser can be conveniently adsorbed on a blackboard when the blackboard eraser is not used.
