Description

A kind of ability of swimming automatically cleaning is except trace blackboard eraser

Technical field

The utility model belongs to school supply and stationery field, relates to blackboard eraser, and especially a kind of ability of swimming automatically cleaning is except trace blackboard eraser.

Background technology

In modern teaching, although projecting apparatus generally uses, blackboard and chalk remain the important tool in teaching, still have irreplaceable status in classroom.When the chalk writing of removing on blackboard, the main common blackboard eraser adopting with bristle traditionally, this common blackboard eraser in use can cause chalk dust to fly upward in classroom, not only make desk, hair and clothes etc. all be stained with one deck white powder, also can distribute a kind of special smell, easily cause the diseases such as chronic pharyngitis, this has brought very large harm to teachers and students healthy.

In order to solve the problems referred to above of the common blackboard eraser of bristle-type, prior art has adopted a lot of modes to make blackboard clean, and concrete grammar is various, but these methods exist a lot of shortcomings, and such as big energy-consuming, heaviness, use inconvenience or dust removing effects are not good etc.So, still need the blackboard eraser product that a kind of environment protecting is good, easy to use, small and exquisite and cost is low.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the ability of swimming automatically cleaning that a kind of environment protecting is good, easy to use, small and exquisite and cost is low to remove trace blackboard eraser.

The technical scheme that the utility model is realized object is:

A kind of ability of swimming automatically cleaning is except trace blackboard eraser, comprise blackboard eraser shell, water box, collodion ring pad, flexible drive axle, driven shaft, soft support axle, sponge sucks in water post, dropper, at the top of square blackboard eraser shell setting-in water box, blackboard eraser shell internal upper part below water box axis position is provided with dropper by the bearing of both sides, the both sides of this dropper are communicated with the water in water box by water pipe, the outer coaxial sleeve of dropper is equipped with that sponge sucks in water post, on dropper wall, uniform interval is shaped with delivery port, the driven shaft of a pair of lateral symmetry is installed by bearing on the blackboard eraser shell of dropper both sides, in blackboard eraser shell below driven shaft is oblique, position, bottom is provided with the flexible drive axle of a pair of lateral symmetry by bearing, these two flexible drive axles have a collodion lasso with outer shaft sleeve, between two flexible drive axles and a soft support axle is also installed at grade, this soft support axle also has a collodion lasso with outer shaft sleeve, at flexible drive axle, soft support axle, the common collodion ring pad that is wound around on driven shaft and sponge sucks in water post, the lower surface that this collodion ring pad exposes blackboard eraser shell.

And, in the each symmetry of two side ends of blackboard eraser shell, being embedded with one and scraping mud box, this is scraped mud box and is being shaped with a dirt-scraping plate in the face of collodion ring pad position, and this is scraped mud box and is also embedded with a setting-in lid, by setting-in lid, the chalk plaster of scraping in mud box can be poured out.

And the described delivery port that uniform interval is shaped with on dropper wall is bell, in the face of sponge sucks in water, post direction is enlarging to this delivery port.

Advantage of the present utility model and good effect are:

1, this blackboard eraser adopts the wiping tool of collodion ring pad as chalk dust, utilize the feature that collodion ring pad space is large, water suction is many, make chalk dust in the water of collodion ring pad, dissolve and to carry out dust adsorption, avoided the harm to teachers and students' health of flying upward of chalk dust, practical, cost is low, simple to operate, conveniently popularizes.

2, this blackboard eraser adopts the water filling source of dropper as collodion ring pad, and dropper adopts bell, large with the contact area of sponge sucks in water post, can keep full water state, guarantees the wiping effect of blackboard eraser.

3, this blackboard eraser is also provided with two dirt-scraping plates in the both sides of collodion ring pad, and the chalk plaster that collodion ring pad outer surface can be adsorbed is hung and sent into and scrapes in mud box, has guaranteed the automatically cleaning of collodion ring pad, has improved the service life of collodion ring pad.

4, the both sides transmission of the collodion ring pad of this blackboard eraser adopts soft lasso, in middle part, is also provided with soft support axle, top adopts that sponge sucks in water, and post presses down and water filling, the two ends of all power transmission shafts all adopt bearing, when guaranteeing the fast running of the smooth and easy cunning of whole transmission system, also can effectively guarantee the water holding capacity of blackboard eraser and when blackboard wiping, have certain downforce buffering, form flexible transmission system, greatly improved wiping ability and the effect of blackboard eraser.

5, this blackboard eraser reasonable integral structure, design science is ingenious, and perfection has overcome the problem that existing blackboard eraser exists, and is the regeneration product of existing blackboard eraser, compared with like product, has more competitiveness and wide market prospects.
