Abstract

The utility model discloses an ink type chalk, which is suitable for various color ink and can replace the existing chalk. The color of the words is the same as the existing chalk with various colors when writing on blackboards with the utility model. The ink type chalk comprises a chalk cover (1), a chalk head (2), a plastic plate (3), a suction pipe (4) and a chalk holder (5). The utility model is characterized in that the chalk head adopt s semicircle sphere and can be tightly sheathed on the plastic plate, so the writing is sanitary and clean, and the health of the teachers and the students can be protected. The utility model has the advantages of convenient manufacture and low cost. A suction pipe (4) can be taken off after use in order to suck ink again, and the utility model can rewrite for many times.

Description

Chalk using ink

In the school eduaction activity, the chalk educational supply that is absolutely necessary, it and blackboard friction are stayed on the blackboard chalk dust, and in the process of writing and wiping, a large amount of chalk dusts enter people's oral cavity, nostril etc.For a long time, suffer teachers and students' detest deeply, and have a strong impact on teachers and students' health.After chalk makes moist in addition, fracture easily.Now mainly containing lime with chalk makes.This has a strong impact on for respiratory tract.Problem hereto, for a long time, Here it is one press for and solve and the problem that does not solve always.

The purpose of this utility model provides the writing device of a kind of energy suction and ink bleed water, solves above-mentioned existing problems.

The purpose of this utility model is achieved in that at tight respectively cover nib in the two ends of plastic plate and suction pipe, nib can be contacted with suction pipe be connected, after suction pipe sucted ink, ink just was seeped on the nib by suction pipe, thereby guarantee that this chalk during paddling, can stay color on blackboard.

The utility model is because use ink as dyestuff, so do not have dust in the process of writing and wiping.Simultaneously because this chalk uses ink as dyestuff, so use it existing more economical with chalk than using.It can use multiple color inks in addition, on blackboard, write smoothly, and the chromaticness of its word and existing multiple color chalk the same (if can change the black blackboard into White writing-board, effect is better, and green blackboard need not change), wipe and smear conveniently.Its external form slightly is coarser than existing chalk, writes comfortable.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is according to the profile that can blend the writing device that blots that the utility model proposes.

Describe the details and the working condition of the concrete device that the utility model proposes in detail below in conjunction with Fig. 1:

This device comprises that the afterbody of the pen cap ［ 1 ］, nib ［ 2 ］ contacts and penholder ［ 5 ］ with suction pipe ［ 4 ］ in plastic plate ［ 3 ］ lining.

Nib ［ 2 ］ is exposed the part semicircle sphere at plastic plate ［ 3 ］, and when writing, because the effect of power, nib ［ 2 ］ can inwardly be compressed into gradually, so the afterbody of nib ［ 2 ］ adopts circular platform type, angle of deviation is preferably in 5 °～10 °.The effect of plastic plate ［ 3 ］ is exactly to allow nib ［ 2 ］ contact with suction pipe ［ 4 ］ be connected, and the length on the top of plastic plate ［ 3 ］ is at 5-10mm, and a bit protrude at the middle part of plastic plate ［ 3 ］, mainly is to make a distinction the pen cap ［ 1 ］ and penholder ［ 5 ］.Suction pipe ［ 4 ］ contacts with nib ［ 2 ］, length is at 45-60mm, its outside is a thick plastic foil, and inside is sponge, and ink just enters from sponge, be seeped into again on the nib ［ 2 ］, behind the tight cover of penholder ［ 5 ］ and plastic plate ［ 3 ］, suction pipe ［ 4 ］ and nib ［ 2 ］ are contacted, put the pen cap ［ 1 ］ again, just make whole device constitute one, this pen in use length at 75-90mm.

Ink type chalk is easy to make, and price is low.As long as ink uses up the back and takes off suction pipe ［ 4 ］, suck same ink again, just can use repeatedly.

Claims
