Abstract
The utility model discloses a board eraser adopting a cleaning solution to erase handwritings, which comprises a holding part and an erasing part. The erasing part is mounted on the front panel of the holding part. A solution storage cavity is arranged inside the holding part. A liquid delivery tube is embedded on the front panel of the holding part, one end of the liquid delivery tube is sealed, and the other end thereof extends into the solution storage cavity; a small hole is formed on one side of the liquid delivery tube positioned on the front panel of the holding part facing to the erasing part. The holding part is made of plastics or rubbers with good elastic deformation. The board eraser has the advantages of reasonable structure and convenient application. When the board eraser is applied, the holding part is deformed under the action of external force to extrude the cleaning solution in the solution storage cavity to decompose the handwritings by a chemical method.
Description
Technical field
The utility model relates to a kind of teaching stationery, particularly a kind of blackboard eraser that adopts cleaning fluid to wipe writing.
Background technology
Continuous progress along with society, because writing on the blackboard dust in erase process ambient influnence healthy to teachers and students and the classroom that chalk is write is bigger, a lot of areas with good conditionsi begin to be equipped with lettering pen to teacher gradually and write writing on the blackboard, one adopts lettering pen to write does not have dust when the writing on the blackboard writing is clear to be wiped, two come the use of lettering pen more to meet daily writing style.At present, the blackboard eraser that use in last lettering pen collocation that sell and above-mentioned in market mostly is the sponge blackboard eraser, its principle is exactly with sponge writing to be wiped down, long-time a large amount of fouling products that used sponge blackboard eraser surface attachment, clean degree when needing often cleaning to wipe writing with assurance, this kind blackboard eraser has in use brought great inconvenience to teaching.
The utility model content
The utility model provides a kind of blackboard eraser that adopts cleaning fluid to wipe writing at the defective that needs in the sponge blackboard eraser use in the prior art in time to clean, and this kind blackboard eraser is easy to use, wipes clean.
The utility model at the technical solution that above-mentioned defective adopts is:
Adopt cleaning fluid to wipe the blackboard eraser of writing, it comprises: grip part and wipe portion, the portion of wiping is installed on the front panel of grip part, inside, grip part is liquid storage cylinder, on the front panel of grip part, embed woven hose, the end sealing of woven hose, the other end gos deep in the liquid storage cylinder, the woven hose that is positioned at the grip part front panel has aperture in its side towards the portion of wiping, and plastics or rubber are made preferably by elastic deformation in the grip part.
Upper end, above-mentioned grip part is provided with unidirectional conducting valve, and the longitudinal sectional view of unidirectional conducting valve family of power and influence core is similar to " worker " shape, and the support portion of spool is clamped in the waist of spool.
The transverse sectional view of above-mentioned spool is circular, at four the vertical notches that have of the support portion of spool equal intervals.
Above-mentioned unidirectional conducting valve is detachable the connection with the grip part.
Above-mentioned woven hose is positioned at the end sealing of front panel bottom, and the other end is walked around the bottom that is deep into liquid storage cylinder from the top, grip part.
The part that above-mentioned woven hose is positioned at the grip part front panel equidistantly has a plurality of apertures.
Rear portion, above-mentioned grip part is an arcuate structure.
The above-mentioned portion of wiping is a sponge for the double layer design internal layer, and skin is cloth or felt.
The beneficial effects of the utility model: this kind adopts cleaning fluid to wipe the blackboard eraser of writing, have rational in infrastructure, advantage easy to use, make the grip part that deformation take place by applied external force during use, extrude the cleaning fluid that is contained in the liquid storage cylinder and with chemical method writing is decomposed, the long-time use do not need blackboard eraser is done any cleaning yet; The rear portion, grip part is an arcuate structure, has the advantage that grips good hand touch.
Description of drawings
Fig. 1 wipes the blackboard eraser grip part side sectional view of writing for adopting cleaning fluid;
Fig. 2 is a blackboard eraser grip part front view;
Fig. 3 is the longitudinal sectional view of unidirectional conducting valve;
Fig. 4 is the vertical view of unidirectional conducting valve.
Below in conjunction with accompanying drawing the utility model is elaborated:
The specific embodiment
In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, adopt cleaning fluid to wipe the blackboard eraser of writing, it comprises: grip part 1 and wipe portion, plastics or rubber are made preferably by elastic deformation in grip part 1, the rear portion of grip part 1 is an arcuate structure, the portion of wiping is a sponge for the double layer design internal layer, and skin is cloth or felt, and the portion of wiping is installed on the front panel of grip part.Inside, grip part is liquid storage cylinder 101, embeds woven hose 2 on the front panel 102 of grip part 1, and woven hose 2 is positioned at the end sealing of front panel 102 bottoms, and the other end is walked around the bottom that is deep into liquid storage cylinder 101 in 1 top from the grip part.The woven hose 2 that is positioned at grip part front panel 102 equidistantly has a plurality of apertures 201 in its side towards the portion of wiping.1 upper end, grip part is provided with unidirectional conducting valve 3, unidirectional conducting valve 3 and grip part 1 adopts that screw-type is detachable to be connected, the transverse sectional view of unidirectional conducting valve family of power and influence core 301 is circular, its longitudinal sectional view is similar to " worker " shape, the support portion 302 of spool 301 is clamped in the waist of spool 301, support portion 302 equal intervals of spool 301 have four vertical notches 303.
During use, the blackboard eraser of the hand-held cleaning fluid of having packed into, finger pushes grip part 1 gently, make grip part 1 that the elastic deformation internal volume take place and dwindle, liquid storage cylinder 101 internal gas pressures increase, and the spool 301 of unidirectional conducting valve 3 rises at the effect upper/lower positions of air pressure, with four on the support portion 302 vertical notch 303 sealings, because the effect of air pressure cleaning fluid this moment is extruded in liquid storage cylinder 101, is sprayed on uniformly in the portion of wiping by a plurality of apertures 201 on the woven hose then, just can wipe writing.After the cleaning fluid ejection, allow grip part 1 slowly reply original shape, the air pressure in the liquid storage cylinder 101 is lower than external pressure, spool 301 is because gravity effect whereabouts, air in the liquid storage cylinder 101 reaches air pressure balance by notch 303 and extraneous conducting, and is ready for pushing cleaning fluid next time.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to the protection domain of utility model.
