Abstract
The utility model relates to an electric heating steam-type dustproof blackboard, in particular to an electric heating evaporative water dustproof blackboard. The electric heating steam-type dustproof blackboard is characterized in that the periphery of the board surface is embedded with an edge strip which is provided with power supply jacks, a safety socket and a switch button; an indicating lamp hole is internally provided with an indicating lamp; the switch is provided with the switch button; the safety socket is internally provided with a fuse wire; an electric heating wire is sheathed with an insulating pipe; a heat-conducting protecting layer is combined by a thin metal plate and a board with the board surface being bright water-absorbing thin rubber board, the insulating layer is fixed on a plate frame chassis; and the insulating layer is formed by stirring paste sodium silicate salt and pearl salt, and is arranged at the bottom part of the electric heating wire. The electric heating steam-type dustproof blackboard has the effects of being simple in structure and convenient for operation, clear and clean if a blackboard eraser is wet to clean the blackboard surface, sanitary and clean in air environment of a classroom, and beneficial to body health of a teacher and students, removing powdery dust by the blackboard eraser without flying, having no marks for the cleaned blackboard surface, and having low cost and being widely used for blackboards of colleges and primary and middle schools.
Description
Technical field:
The utility model relates to a kind of electric-heating steam formula dustproof blackboard, particularly electric heating evaporation moisture dustproof blackboard.
Background technology:
At present, dust from flying on the blackboard in the prior art pollutes classroom environment, and the academics and students is healthy in harm, adopts dust absorption blackboard eraser, and dust suction is not thorough, photoelectricity blackboard structure complexity, and special pen is write, and the cost height is difficult for wide popularization and application.
Summary of the invention:
The purpose of the utility model electric-heating steam formula dustproof blackboard is to overcome above-mentioned shortcoming and design a kind of electric-heating steam formula dustproof blackboard, and it is to adopt the heating wire heating to make moistening plate face steam, and dust is attached to not flying upward powered-down when not using on the blackboard eraser.Blackboard eraser adopts the moistening cotton of multilayer to make, and blackboard eraser can only forward impelling be wiped, and can not back wipe, in order to avoid influence the cleaning of plate face, nuzzling up, the plate face is clear totally to leave no trace.
The utility model electric-heating steam formula dustproof blackboard takes following technical scheme to realize; it is to put edge strip by inlaying on the plate face all around; edge strip is provided with supply hub and safety socket and shift knob; be provided with indicator lamp in the indicator lamp hole; switch is provided with shift knob; be provided with fuse in the safety socket; be nested with insulation tube on the heating wire; the heat conduction protective layer is that metal sheet and plate face are that bright and clean water imbibition TR thin rubber plate is bonding; be fixed on the grillage chassis by heat-insulation layer; heat-insulation layer stirs pearl salt by the pasty state metso and constitutes, and heat-insulation layer is arranged at the heating wire bottom.
The effect of the utility model electric-heating steam formula dustproof blackboard is simple in structure, easy to operate, it is clear clean that moistening blackboard eraser is coated with the wiping board face, dust is removed by the blackboard eraser band, and dust does not fly upward, classroom air ambient hygiene, it is healthy to be beneficial to the academics and students, the blackboard surface that nuzzles up leaves no trace, and cost is low, is widely used in the blackboard of universities, middle and primary schools.
Description of drawings:
The utility model electric-heating steam formula dustproof blackboard will describe in further detail in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the utility model electric-heating steam formula dustproof blackboard.
