Abstract

The utility model relates to an electric blackboard eraser which relates to a blackboard eraser. Aimed at the shortcomings of the existing blackboard eraser that a blackboard box of the existing blackboard eraser is inlaid with flannelette, the flannelette is used for erasing chalk dust on a blackboard, the chalk dust flies up all around, and sanitation is not ensured when people breathe in the lung; meanwhile, the flying up chalk dust results in environment pollution, etc. The electric blackboard eraser which has simple structure and adopts an electrically operated eraser is provided. The utility model adopts the technical scheme that an electric motor 2 with a conducting wire 10, a flannelette roll 6 and a battery box 9 are arranged in an eraser box 1, a belt 4 is arranged between a belt pulley 3 which is arranged on an output shaft of the electric motor 1 and the belt pulley 3 which is arranged on a shaft 5 of the flannelette roll 6, the front end surface of the eraser box 1 is inlaid with flannelette strips 8, the back surface is provided with a handle 11 with a switch 12 and the side surface is provided with a dust absorption pipe 7.

Description

The driven blackboard brush
One, technical field
The utility model relates to blackboard brush, especially a kind of driven blackboard brush.
Two, background technology
The traditional blackboard brush is to adopt the blackboard brush box to be embedded with the flannelette structure, utilizes flannelette to wipe powder on the blackboard, exists powder and flies upward everywhere, and the people sucks in the lung extremely unhygienic, flies upward powder simultaneously and causes weak points such as environmental pollution.
Three, summary of the invention
The purpose of this utility model is that to carry arch a kind of simple in structure, adopts the driven blackboard brush of Electrically operated brush.
The technical scheme that the purpose of this utility model adopted is, brush box, motor, flannelette roller are formed, device has motor, flannelette roller, the battery case of band lead in its brush box, between the belt pulley of the output shaft of motor dress and the shaft upper pulley of flannelette roller belt is housed, is embedded with the flannelette bar on the brush box front end face, the back side has the handle of belt switch, side that sweep-up pipe is arranged.
The utility model, the positive pole of battery case connect an end of switch, a lead of another termination motor of switch, and another lead of motor connects the negative pole of battery case.
Load onto battery when using the utility model earlier and connect dust catcher, utilize the switch connection motor circuit of handle, make the axle rotation of motor, drive belt pulley, belt drives the rotation of flannelette wheel then, and the flannelette roller is wiped powder on the blackboard, and powder goes to dust catcher through sweep-up pipe.Characteristics such as the utility model is simple and compact for structure, and fabrication and installation are convenient, and result of use is obvious.
