Abstract
The utility model relates to an electric steam type dustproof blackboard, belonging to a dustproof blackboard which uses the electric heating to vaporize moisture. The utility model is formed by that an insulation tube is sheathed on a heating cord, a heat conducting protective layer is formed by that a thin metal board and a thin rubber board, wherein, the board surface of which is smooth and has the function of water absorption, are bound, and are fixed on a base board of a board frame by an insulation layer, the insulation layer is formed by that pasty sodium silicate salts are agitated with pearl salts, the insulation layer is arranged at the bottom part of the heating cord. The utility model has the advantages of simple structure, convenient operation, low cost, and no fly for dust. The board surface is wiped by a wet board wiper to clear and clean, and the board surface which is wiped has no mark, and the dust is brought and removed by the board wiper. The utility model is widely applied to blackboards of colleges, middle schools, and elementary schools.
Description
The utility model electric heating steam formula dustproof blackboard belongs to electric heating evaporation moisture content dustproof blackboard.
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.
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, the clear wash rice of plate face that nuzzles up totally leaves no trace.
The utility model electric heating steam formula dustproof blackboard takes following technical scheme to realize; it is to be made of plate face and heating wire and grillage chassis; edge strip and supply hub and switch are set on the grillage chassis; be provided with fuse in the safety socket; switch is provided with shift knob, is provided with indicator lamp in the indicator lamp hole, and the heat conduction protective layer is a metal sheet; heat-insulation layer is nested with the waterproof insulation pipe for the pasty state metso stirs pearl salt on the heating wire.The plate face is bright and clean water imbibition TR thin rubber plate, and the bonding one deck metal sheet in the plate face back side is fixed on the grillage chassis by heat-insulation layer by screw, and heating wire is provided with heat-insulation layer, and is moist by heating wire generation thermal evaporation moisture content on the plate face, reaches plate face sanitation and hygiene.
The effect of the utility model electric heating steam formula dustproof blackboard is simple in structure, easy to operate, it is clean that moistening blackboard eraser is coated with the clear wash rice of 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.
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 dustproof blackboard.
Fig. 2 is the circuit diagram of the utility model electric heating steam formula dustproof blackboard.
Fig. 3 is the partial sectional view of the utility model electric heating steam dustproof blackboard.
With reference to Fig. 1,2,3, the utility model electric steam type dustproof blackboard, it is to put by inlaying all around on the plate face 1 Edge strip 2, edge strip 2 are provided with supply hub 3 and safety socket 4 and switch 7, are provided with finger in the indicator lamp hole 6 Show lamp 10, switch 7 is provided with shift knob 5, is provided with fuse 8 in the safety socket 4, is nested with on the heating wire 9 Insulation tube 13 and heat conduction protective layer 11 metal sheets and heat-insulation layer 12 stir pearl salt by the pasty state metso Consist of heat-insulation layer 12, plate face 1 is that bright and clean water imbibition TR thin rubber plate is bonding with metal sheet, the heat conduction protection Layer 11 is metal sheet, is fixed on the grillage chassis 14 by heat-insulation layer 12. During use shift knob 5 is left Open, moistening blackboard eraser is done moist water evaporates by heating wire 9 after being coated with wiping board face 1.
The embodiment of the utility model electric heating steam formula dustproof blackboard; it is to put edge strip 2 by inlaying on the plate face 1 all around; edge strip 2 is provided with supply hub 3 and safety socket 4 and shift knob 5; be provided with indicator lamp 10 in the indicator lamp hole 6; switch 7 is provided with shift knob 5; be provided with fuse 8 in the safety socket 4; be nested with insulation tube 13 on the heating wire 9; heat conduction protective layer 11 is that metal sheet and plate face 1 are bonding for bright and clean water imbibition TR thin rubber plate; be fixed on the grillage chassis 14 by heat-insulation layer 12; heat-insulation layer 12 stirs pearl salt by the pasty state metso and constitutes, and heat-insulation layer 12 is arranged at heating wire 9 bottoms.
