Abstract
The utility model relates to a blackboard eraser device for biochemical chalk, which belongs to the technical field of teaching aids, and mainly comprises a blackboard eraser and a special appliance for serving the blackboard eraser, wherein the special appliance comprises a shell, a bottom board, a dirt storage drawer, a wave-shaped-bulge sponge, and a holder, wherein the bottom board is fixedlyarranged at the lower part of the shell, and the dirt storage drawer is inserted into one end of the shell; and the wave-shaped-bulge sponge is arranged in a blackboard eraser chamber in which water is stored, and the blackboard eraser is arranged on the wave-shaped-bulge sponge. A wet blackboard eraser wiping cloth is scraped by special scraping boards after becoming dirty, so that the dirt can automatically flow into the dirt storage drawer. The blackboard eraser device is specially designed to rub out characters written by biochemical chalk, and has convenient use, no dust production, environmental protection and safety.
Description
Technical field
The utility model relates to a kind of device for blackboard eraser that is used for biochemical chalk, and it belongs to the teaching aid technical field.
Background technology
The micro-ion of tradition chalk dust has very strong germ adsorption capacity, and chalk dust contains compositions such as heavy metal cadmium, lead, manganese simultaneously.In order to solve the problem that traditional chalk dust flies away, a lot of manufacturers propose dust-free chalk, micronic dust chalk, liquid chalk.Now dust-free chalk of selling on the market or micronic dust chalk adopt and add the method that grease or polyalcohols material are made binder in original chalks, make its proportion bigger, be difficult for dispersing, but actual conditions are unsatisfactory.Chalk write with erase process in can produce a large amount of dust, swim in for a long time aerial, the severe contamination room air.The liquid chalk adopts the design concept of blank pen, adopts independent ink storehouse structure, repeatedly the can ink.Serve as a teacher when using and make it unlatching and provide ink to nib by the spring valve of written transfer function power to ink storehouse.But the liquid chalk needs special-purpose black (green) plate, perhaps pastes special-purpose pad pasting on existing blackboard or green plate surface, need carry out the blackboard transformation, and chalk liquid can shoal very soon through the volatilization writing after writing, and the classmate in recoil often reflection does not see the writing on the blackboard content.The liquid chalk is normally imparted knowledge to students owing to problems affect such as a liquid supply is not smooth usually appear in the writing process in the structural design reason.
A kind of biochemical chalk of exploitation does not produce dust in use now, just can clean with wet cloth, and thing followed problem is that traditional blackboard eraser has not satisfied instructions for use.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, the utility model provides a kind of device for blackboard eraser that is used for biochemical chalk.This device for blackboard eraser aims at wipes the biochemical chalk design, easy to use, does not produce dust, Environmental Safety.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of device for blackboard eraser that is used for biochemical chalk, it mainly comprises a blackboard eraser, also comprises a special implement for the blackboard eraser service.Described special implement comprises that a housing, base plate, one deposit dirty drawer, a wave heave sponge and a mounting, base plate is fixedly mounted on lower part of frame, deposit of the end insertion of dirty drawer from housing, it is indoor that the wave heave sponge is placed on blackboard eraser, blackboard eraser place the wave heave sponge above; Be connected to each other together in the slot of housing by the sidewall insertion mounting of opening.
Described blackboard eraser is provided with the wiper that can take off cleaning.
The outside in described blackboard eraser chamber has three faces to be provided with sewage absorbing plate, and the shape of sewage absorbing plate adopts ∩ shape structure, and the both sides of the sewage absorbing plate of employing straightway are equipped with puts dirty groove, adopts the both sides of the sewage absorbing plate of arc to be equipped with cavity.
Described mounting adopts L shaped structure, is provided with the side fixing screw hole on vertical surface, is provided with fixing screw hole down on the bottom surface.
The beneficial effects of the utility model are: this device for blackboard eraser that is used for biochemical chalk, it mainly comprises a blackboard eraser and the special implement for the blackboard eraser service.Special implement comprises that a housing, base plate, one deposit dirty drawer, a wave heave sponge and a mounting, base plate is fixedly mounted on lower part of frame, deposit of the end insertion of dirty drawer from housing, it is indoor that the wave heave sponge is placed on the blackboard eraser that has water, blackboard eraser place the wave heave sponge above.Moistening blackboard eraser wiper is after use is dirty, and one draws together on ad hoc sewage absorbing plate, and dirt can flow into automatically deposit dirty drawer.This device for blackboard eraser aims at wipes the biochemical chalk design, easy to use, does not produce dust, Environmental Safety.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a kind of structure front view that is used for the blackboard cleaning device of biochemical chalk.
Fig. 2 is a kind of structure vertical view that is used for the blackboard cleaning device of biochemical chalk.
Fig. 3 is the A--A structure cutaway view among Fig. 2.
Among the figure: 1, housing, 1a, sewage absorbing plate, are put dirty groove at 1b, 1c, pillar, 1d, blackboard eraser chamber, 1e, cavity, 1f, sidewall, 2, base plate, 2a, mounting screw, 3, deposit dirty drawer, 4, the wave heave sponge, 5, blackboard eraser, 5a, wiper, 6, mounting, 6a, slot, 6b, side fixing screw hole, 6c, following fixing screw hole.
The specific embodiment
Fig. 1,2,3 shows a kind of structure chart that is used for the blackboard cleaning device of biochemical chalk.It mainly comprises a blackboard eraser 5 and one special implement for blackboard 5 services, special implement comprise a housing 1, base plate 2, one deposit dirty drawer 3, a wave heave sponge 4 and a mounting 6.4 mounting screw 2a of base plate 2 usefulness are fixedly mounted on 4 pillar 1c of housing 1, deposit dirty drawer 3 and insert from an end of housing 1, and wave heave sponge 4 is placed in the blackboard eraser chamber 1d that has water, blackboard eraser 5 place wave heave sponge 4 above.
In the outside of blackboard eraser chamber 1d, there are three faces to be provided with sewage absorbing plate 1a, the shape of sewage absorbing plate 1a adopts ∩ shape structure, and the both sides of the sewage absorbing plate 1a of employing straightway are equipped with puts dirty groove 1b, adopts the both sides of the sewage absorbing plate 1a of arc to be equipped with cavity 1e.Blackboard eraser 5 adopts the magic card to fix a wiper 5a that can take off cleaning, and wiper 5a adopts the suction cloth to make.The time spent does not place on the water-filled wave heave sponge 4 owing to blackboard eraser 5, so the wiper 5a of blackboard eraser 5 is also always moistening, after having wiped blackboard, the residue of biochemical chalk can accumulate on the wiper 5a, as long as the wiper 5a of blackboard eraser 5 one is drawn together on sewage absorbing plate 1a gently, the residue of biochemical chalk will flow into to be put in the dirty groove 1b, finally flows into by ad hoc cavity 1e to be arranged in the following dirty drawer 3 of depositing.
