Description
Technical field
The utility model relates to daily necessities fields, more particularly, to the new type blackboard dust-erasing ring of school instruction
Protect case.
Background technique
Campus classroom teaching in China, writing on the blackboard are essential links；In the current generation, China still has very much
The writing on the blackboard of school uses normal blackboard and chalk, needs to clean using blackboard eraser after the traditional instruction of teacher's each round black
Chalk writing on plate.Blackboard eraser after this multiple use, inevitably accumulates a large amount of chalk dust on the soft face of blackboard eraser,
In order to continue to use blackboard eraser, teacher or students, which are generally tapped or scraped on nearest vacant lot or dustbin, to erase the board
It wipes, removes the chalk dust accumulated on the soft face of blackboard eraser.This behavior inevitably causes chalk dust to wave, and influences to teach indoor
The health of air environment and Faculty and Students.
Utility model content
The technical problem to be solved by the present invention is to provide what is accumulated on a kind of effectively practical tool removal blackboard eraser
Chalk dust.
In order to solve the above technical problems, the technical solution adopted by the utility model is: a kind of novel blackboard eraser dedusting environment friendly
Case, including cabinet, scrape net, collect grey funnel, ash barrel, piston cylinder and piston；
It scrapes net to be mounted in cabinet and the intracorporal space of case is divided into two, scraping net can be used stainless steel and iron silk screen
Production；The surface of cabinet, which is provided with, uses hole for blackboard eraser disengaging, is higher than using the position in hole and scrapes net, generally set using hole
It is calculated as circle, size is greater than the size at year fist；
Collect grey funnel to be mounted in cabinet, collects grey collection funnel from the chalk dust for scraping the leakage of net mesh；
Ash barrel is mounted on the bottom for collecting grey funnel；
Piston cylinder connect and is connected with ash barrel, and the side wall of piston cylinder is provided with the via hole entered for chalk dust, living
Plug is mounted in piston cylinder；
The bottom of ash barrel is provided with the template cylinder for manufacturing chalk pen base.
After accumulating a large amount of chalk dusts on the soft face of blackboard eraser, student can hold blackboard eraser stretching using hole from cabinet
In cartonning body, the soft face of blackboard eraser is being scraped into online reciprocal scratch, the chalk dust fallen that shakes leads into storage through the grey funnel of collection
Grey cylinder.In normal use, template cylinder is blocked by nut cap；After accumulating enough chalk dusts in ash barrel, student can be with
Suitable water is added into ash barrel, then utilizes piston press chalk dust, is made chalk pen base using template cylinder, is opened lid
Cap takes out moist base and is re-used as chalk use after drying.
Further, described to use the tubaeform resistance dirt pad that useful elastic material production is set on hole；It avoids in cabinet
The chalk dust to wave is to external diffusion.
Further, the observation panel of useful transparent material production is arranged in the surface of the cabinet.
The utility model has the advantages that the environmental-protection box of simple structure and strong practicability of (1) the utility model, using scraping net scratch blackboard eraser
The chalk dust accumulated on the soft face of blackboard eraser can be effectively removed and chalk dust is prevented to drift to teaching in indoor air, protection is taught
The respiratory health of teacher and student.(2) environmental-protection box of the utility model is provided with template cylinder in the bottom of ash barrel, utilizes piston
The chalk dust of collection can be remake into chalk with template cylinder, realize resource recycling.(3) ring of the utility model
It protects case and tubaeform resistance dirt pad is set on using hole, prevent the intracorporal chalk dust of case to external diffusion.(4) ring of the utility model
It protects case and is provided with observation panel in tank surface, convenient for the reserves for the chalk dust that observation cabinet is collected.
Detailed description of the invention
Fig. 1 is 1 novel blackboard eraser dedusting environment friendly box structure schematic diagram of embodiment.
Wherein: 1, cabinet；11, using hole；2, net is scraped；3, collect grey funnel；4, ash barrel；5, piston cylinder；51, it is connected
Hole；6, piston；7, dirt pad is hindered；8, template cylinder；9, observation panel.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Embodiment 1
As shown in Figure 1, the novel blackboard eraser dedusting environment friendly case of the present embodiment, including cabinet 1, scrape net 2, collect grey funnel 3,
Ash barrel 4, piston cylinder 5 and piston 6；
It scrapes net 2 to be mounted in cabinet 1 and the space in cabinet 1 is divided into two, scrapes net 2 by stainless steel and iron silk screen system
Make；The surface of cabinet 1, which is provided with, uses hole 11 for the circular of blackboard eraser disengaging, is higher than using the position in hole 11 and scrapes net 2；Make
With the tubaeform resistance dirt pad 7 that useful elastic rubber material production is arranged on hole 11；
The grey funnel 3 of collection is mounted in cabinet 1, is collected grey funnel 3 and is collected from the chalk dust for scraping the leakage of 2 mesh of net；
Ash barrel 4 is mounted on the bottom for collecting grey funnel 3；
Piston cylinder 5 connect and is connected with ash barrel 4, and the side wall of piston cylinder 5 is provided with the via hole entered for chalk dust
