Abstract

The utility model discloses an electric dust-collecting blackboard eraser which can absorb the dust. The utility model produces a casing by using the engineering plastics and is provided with two 12V mini motors. The power supply is switched on to drive an impeller type sucking disc rotate, and the formed centrifugal force makes the dust enter a dust box through the side of a hair fixing board and a middle ring-shaped hole. Simultaneously the hair fixing board can be changed after a hair brush is damaged. The environment pollution caused by the dust is prevented, and the body health of teachers and students is guaranteed.

Description

Electric dust-collecting blackboard eracer

The utility model relates to a kind of by AC-DC, prevents dust from flying, the electric dust absorption instrument that is beneficial to health.

Blackboard eraser in the past is very easy, on a plank, and the sticking hairbrush that is stained with of one side, the teacher is effort not only in use, and the bigger dust that flies upward of harm sucked serious harm in teachers and students' the lung in a large number teachers and students healthy.Also extremely unfavorable to the sanitation and hygiene in classroom simultaneously.

The purpose of this utility model provides a kind of device that absorbs dust, and it can prevent effectively that dust from flying upward everywhere.

The purpose of this utility model is achieved in that with ABS engineering plastics makes a shell, in adorn two micromachines, after connecting power supply, impeller formula sucker, rotation at a high speed, formed centrifugal force makes dust looping pit other by hairbrush and its bottom enter the dirt box.

Hairbrush uses up replaceable solid hair plates simultaneously, and main body can be used for a long time.

Owing to adopted above technology, the utility model had both prevented dust polluting environment, had guaranteed that again teachers and students' is healthy.

Further specify concrete device details of the present utility model and working condition again below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model

In Fig. 1, two 12 volts micromotor 8 is housed on this blackboard eraser main body 1, motor 8 is fixed on the fixed mount 9, fixed mount 9 is connected with main body 1, inhale wheel disc 7 and connect motor 8, hairbrush 3 is embedded on the solid hair plates 5, Gu looping pit 4 and intermediate annular hole 6 are arranged on hair plates 5 limits.Gu hair plates is connected with main body 1 and is replaceable, loam cake 2 is connected with main body 1, there is switch 11 loam cake 2 sides, with input power hole 12, dirt box 13 is connected with main body 1 bottom, and dirt makes air-vent 14 on 13 limits, and dirt cloth 16 is put into dirt box 13, loam cake 2 crown centers have via hole 15, are fastened on the solid lid 10 by hole 15 with standard component.

Power supply is by input hole 12 during the utility model work, starting switch 11 makes driven by motor inhale wheel disc 7 rotations, and along with moving of main body 1, dust sees through the looping pit 4 and the middle looping pit 6 on solid hair plates 5 next doors, enter dirt box 13, the dirt box 13 of can leaving behind during clear dirt gets final product.

The utility model is promptly laborsaving in use like this, prevents that again dust from flying upward everywhere, helps healthy simultaneously again.
