Abstract

The utility model provides a blackboard eraser which comprises a plurality of cleaning holes, a felt wiping seat and a back cover, wherein the back side and the periphery of the back cover are provided with a plurality of solar energy collecting plates, and the back cover is internally provided with a mini dust collector and an electric circuit. When the blackboard eraser is used, the cleaning holes which are arranged at the front side and the periphery of the blackboard eraser are used for absorbing the peripherally-overflowed dust, a center wiping felt is inserted with a main body by the felt wiping seat, and the wiping felt can be inversely buckled on the mini dust collector when the blackboard eraser is cleaned after being used, so that a plurality of dust absorbing holes of the dust collector are near to the wiping felt to absorb the dust. The blackboard eraser can be charged once being put under the sunshine.

Description

The solar energy dust absorption blackboard eraser

Technical field the utility model relates to a kind of realia, especially a kind of dust absorption blackboard eraser that utilizes solar energy as power.

The background technology blackboard eraser is the realia of using always, present widely used blackboard eraser can't stop chalk dust to fly upward, and it is healthy to influence teachers and students, and Small-sized suction cleaner is assembled on the blackboard eraser head it off preferably, but existing dust absorption blackboard eraser needs power consumption, is unfavorable for energy-conserving and environment-protective.

Utility model content the purpose of this utility model is to provide a kind of solar energy dust absorption blackboard eraser, with solve existing blackboard eraser in use chalk dust fly upward air-polluting problem, and provide the energy clean, environmental protection for the dust catcher of blackboard eraser.

The utility model blackboard eraser comprises lancing door, wipes the felt seat, back box, and wherein the back box back side is solar panel around reaching, back box inside is micro-cleaner and electronic circuit.

After adopting said structure, during use, aperture absorbs the dust that overflows around the blackboard eraser front, can tip upside down on the micro-cleaner wiping felt during with the back cleaning, allows the air suction opening of micro-cleaner press close to wipe the felt dust suction.These works are placed under the sunlight promptly chargeable.

The utility model has the advantages that: simple in structure, easy to use, environmental protection and energy saving bring greater convenience for people's use.

Fig. 3 is a structure schematic diagram of the present utility model.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

In front, inside and the structure schematic diagram of Fig. 1, Fig. 2 and blackboard eraser shown in Figure 3, establish lancing door 1 around the blackboard eraser front and absorb the dust that overflows, central authorities wipe felt and peg graft with the micro-cleaner 3 of back box inside by wiping felt seat 2, can tip upside down on the micro-cleaner wiping felt during with the back cleaning, allow the ledge (band air suction opening) of grafting 4 press close to wipe the felt dust suction, solved the problem that felt is difficult to clear up of wiping preferably.The back box back side is provided with solar energy absorption plant 5, is that electric energy drives micro-cleaner work with conversion of solar energy.Twice dust suction controlled by different switches.

Claims

1. a blackboard eraser is characterized in that: in the blackboard eraser back box micro-cleaner is arranged, absorb the dust that overflows by the air suction opening on the blackboard eraser; Blackboard eraser back box surface is solar collector (5), collects the power that solar energy is done micro-cleaner.

2. blackboard eraser according to claim 1 is characterized in that: the wiping felt and can pull down with micro-cleaner and clear up of blackboard eraser.
