Abstract

The utility model discloses an electric dust-free blackboard eraser, comprising a blackboard, guide rails, a transmission chain and a wiping board, wherein the guide rails are mounted at upper and lower sides of the blackboard; the transmission chain is mounted in the guide rails and is controlled by a motor mounted on the guide rails; the wiping board crossly spans between the two guide rails; the wiping board moves along the horizontal direction of the transmission chain to wipe; and the lower end of the wiping board is connected with a hose and one end of the hose is connected with a dust collector; and the wiping board consists of a mechanical frame, a brush and a dustproof cover, the brush is installed below the mechanical frame, and the dustproof cover is sleeved at the outer layer of the mechanical frame. The electric dust-free blackboard eraser effectively controls the flying of chalk powder and the environmental pollution is reduced through collecting the chalk powder in the dust collector; and meanwhile, the electric wiping is adopted so the burden of teachers is reduced, manpower resources are saved while environmental sanitation is protected.

Description

Electric dust-less blackboard is wiped
Technical field
The utility model belongs to a kind of teaching aid, specifically is that a kind of electric dust-less blackboard is wiped.
Background technology
The teacher is as the engineer of the soul, and all need write with chalk every day on class, and present dust-free chalk is not dustless, lets teacher when transmitting wisdom and imparting knowledge, also will receive the puzzlement of chalk dust, the class white powder from head to foot that gets off; Simultaneously, the head of a family also opposes to let children be sitting in the front row because fearing the health problem that children's sucking chalk powder possibly cause.
Find that through practice the diffusion of chalk dust mainly occurs in the process with the blackboard eraser blackboard wiping, so in order to alleviate teacher's work load, healthy for the academics and students researched and developed electric dust-less blackboard wiping system.
The utility model content
The purpose of the utility model has provided a kind of electric dust-less blackboard and has wiped, and adopts wiping-dust suction integrated structure, effectively blackboard wiping, and the maximized chalk dust that siphons away.
The technical scheme of the utility model is achieved in that a kind of electric dust-less blackboard wiping; Comprise blackboard, guide rail (1), driving chain (2) and Wiper plate (4); State the both sides up and down that guide rail (1) is installed in blackboard; Driving chain (2) is installed in the guide rail (1) and by motor (3) control that is installed on the guide rail, Wiper plate (4) is across between two guide rails (1), and Wiper plate (4) carries out wiping with driving chain (2) horizontal motion; Wiper plate (4) lower end connects flexible pipe (5), and an end of flexible pipe (5) connects dust catcher (6).Said Wiper plate (4) comprises mechanism's skeleton (7), hairbrush (9) and dust cover (8), and hairbrush (9) is installed in the below of mechanism's skeleton (7), the skin cover dust cover (8) of mechanism's skeleton (7).
The beneficial effect of the utility model is: the utility model has been controlled wafting of chalk dust effectively, through being collected in chalk dust in the dust catcher, has reduced environmental pollution; Adopt electronic wiping simultaneously, alleviated teacher's burden.When saving human resources, protected environmental sanitation.
