Abstract

The utility model relates to the field of education supplies, and provides an eraser duct collection joint based on a duct collector. The eraser duct collection joint has the characteristics of wide application range, good dust collection effect, simple structure, convenience in use and the like. Dust collecting holes are formed in two sides of a dust collection joint main body, and are communicated with a dust collection connector at the back side of the joint through an inner cavity, and a groove is formed in the other side of the joint. When the eraser duct collection joint is used, an eraser is clamped in the groove of the joint, the connector of the joint is connected with the dust collector, chalk dust can be sucked in the inner cavity through the dust collecting holes in two sides when a blackboard is erased and is further sucked out by the dust collector. According to the eraser duct collection joint, a clean classroom environment can be kept, and indoor breathing hidden danger of students and teachers is eliminated.

Description

A kind of blackboard eraser dust absorption adapter connector based on dust catcher

Technical field

The utility model relates to a kind of dust catcher joint, specifically a kind of blackboard eraser dust absorption adapter connector based on dust catcher.

Background technology

At present, most schools uses is still and is stained with the traditional blackboard that mao matter or suede material make by plastic casing and wipes, and the dust that produces in wiping process flies upward everywhere, and the dust that wipes rear delay is not easy cleaning very much, not only pollute the environment, also can affect healthy after being sucked by the people.Show through investigation, become numerous students, teacher's No.1 healthy hidden danger by " the chalk syndrome " writing on class, bring when erasing the board.Student is from needing at least for 15 years to finishing college at primary school, and health is in these 15 years of the gold period of growing, and but will suffer inevitably the invasion and attack of chalk dust ash.The dais needs the time of work about 40 years to retirement on teacher's slave station, and these 40 years more than half time will be spent in the chalk dust ash, and suffered harm is also well imagined.Therefore, eliminate the meaning that chalk dust has reality.Development from so-called dust-free chalk, micronic dust chalk to new type blackboard illustrates that all people wish to reduce the harm of dust.Yet, until at present, also not having a design or product really to popularize and come, subject matter is that versatility is poor, it is complicated to install, effect is not good etc.Under such background, a kind of design and popularization of chalk dust removing means for eraser of highly versatile become exigence.

Summary of the invention

In order to overcome the drawback of existing product, eliminate chalk dust to the injury of human body.The utility model provides a kind of blackboard eraser dust absorption adapter connector based on dust catcher, by it dust catcher and our blackboard eraser used in everyday is coupled together, and can when erasing the board, simultaneously dust be siphoned away.The characteristics such as it is good that it has pick-up performance, and applicability is extensive, easy to use, simple in structure.

The technical scheme that the utility model adopts is: for being communicated with chamber, the fittings body both sides respectively are provided with a rectangle air suction opening, communicate by the interface of internal chamber with the fittings body top in the dust absorption adapter connector body, and the bottom side of fittings body is provided with a rectangular recess.

When the utility model uses, connector interface is connected dust catcher by sebific duct, blackboard eraser snaps in the rectangular recess of joint, and when erasing the board, chalk dust is by the both sides air suction opening chamber that absorbs, further by the dust catcher sucking-off.

The beneficial effects of the utility model are: when using the utility model to cooperate ordinary blackboard eraser; during blackboard wiping; the dust that fly upward the blackboard eraser both sides all is inhaled in the dust catcher by joint, has stopped the pollution of dust to classroom and air, is conducive to protect indoor environment and teachers and students healthy.
