Abstract

The utility model provides a novel dry-wet eraser. The novel dry-wet eraser comprises a box body, a dry eraser part and a wet eraser part are fixedly arranged in the box body, the dry eraser and the wet eraser are separated by a partition, the dry eraser is of a cleaning cloth, the wet eraser is of a wet sponge externally coated by the cleaning cloth, the box body is a cuboid or cube with an opening at the top, and the partition is of a plastic board. The novel dry-wet eraser has the dry eraser part and the wet eraser part, the wet eraser can wet dust after contacting chalk characters on a blackboard so as to prevent dust from flying all around when the blackboard is erased, thereby preventing a great deal of dust from falling on the clothes and skins of a student on duty or from being inhaled in a respiratory system, and avoiding adverse influence on the body of people.

Description

The Novel dry wet rubbing

Technical field

The utility model relates to a kind of Novel dry wet rubbing.

Background technology

Teacher can often use chalk on class in the school, chalk-writing is after on the blackboard, the student on duty for the day who needs every day is with the chalk writing wiped clean on the blackboard, but the student on duty is after wiping blackboard, the dust that often has a lot of whites sticks on student on duty's hair and clothes, sometimes also can be stained with dust on the face, dust is not only unhygienic, and easily waves; Also can the calcination impact be arranged to skin; More seriously, can produce harmful effect to respiratory system if suck a large amount of dust.

Summary of the invention

Dust easily waves and easily health is produced dysgenic problem when erasing the board in the prior art, and the utility model provides a kind of Novel dry wet rubbing, has solved the problem that dust flies away when blackboard wiping everywhere.

For realizing above-mentioned utility model purpose, the utility model adopts following technical proposals to be achieved:

A kind of Novel dry wet rubbing, it comprises box body, is fixed with xerotripsis and wet rubbing two parts in the described box body, is separated by dividing plate between described xerotripsis and the wet rubbing.

To further improvement in the technical proposal: described xerotripsis is rag.

To further improvement in the technical proposal: described wet rubbing is for being surrounded by the wet sponge of rag outward.

To further improvement in the technical proposal: described box body is open-topped cuboid or square.

To further improvement in the technical proposal: described dividing plate is plastic plate.

Compared with prior art, advantage of the present utility model and good effect are: Novel dry wet rubbing described in the utility model has xerotripsis and wet rubbing, described wet rubbing can be behind the chalk writing on the contact blackboard, wetting dust, when having avoided blackboard wiping, the problem that dust flies away does not everywhere fall on student on duty's clothes, the skin thereby just do not have a large amount of dust, can not suck in the respiratory system yet, avoid people's health is produced harmful effect.

After reading by reference to the accompanying drawings the specific embodiment of the present utility model, other characteristics of the present utility model and advantage will become clearer.

Description of drawings

Fig. 1 is the structural representation of Novel dry wet rubbing in the utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described in further detail.

Embodiment 1

As shown in Figure 1, Novel dry wet rubbing described in the utility model comprises box body 1, is fixed with xerotripsis 2 and wet rubbing 3 two parts in the described box body 1, is separated by dividing plate 4 between described xerotripsis 2 and the wet rubbing 3.Described box body is open-topped cuboid or square, and described dividing plate is plastic plate.Described xerotripsis 2 is converted into cuboid for rag commonly used with rag, can adopt the modes such as binding or bonding that rag is fixed at box body inside.

Described wet rubbing 3 is for being surrounded by the wet sponge of ventilative sopping rag outward, can adopt the common mode such as binding that wet rubbing is fixed at box body inside.

When using the chalk writings of described dried wet rubbing on blackboard wiping, water in the sponge can be wetting with rag, get wet behind the moistening rag dust exposure and then dust, and the rag that is converted into cuboid is when wiping, it can remove the person's handwriting of chalk, guarantee under the clean prerequisite of blackboard eraser, good dust adsorption again is so that dust is difficult for flying upward.Therefore solved because dust from flying drops on problem on people's hair and the clothes, and and then avoided the situation that skin produced calcination and respiratory system is had a negative impact because of dust from flying.Make classmates use not only safety but also health.

The problem that xerotripsis and wet rubbing drop in the blackboard wiping process because rag and wet sponge are fixed in the box body, therefore can not occur in described dried wet rubbing when blackboard wiping.

Above embodiment is only in order to illustrating the technical solution of the utility model, but not limits it; Although with reference to previous embodiment the utility model is had been described in detail, for the person of ordinary skill of the art, still can make amendment to the technical scheme that previous embodiment is put down in writing, perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of the utility model technical scheme required for protection.
