Description
The utility model relates to Eraser with chalk dust absorbing device.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and the big class of office appliance is write or drawing article, and the assistant product group of writing or draw has the technical group field of sucking chalk powder device.Be numbered B43L21/02.
At present, existing and once had about have the sucking chalk powder device the technology demand that chalk dust flies upward everywhere when people are used blackboard eraser all did very fruitful effort, and made many outstanding technology and scheme.As the Decree of Patent Office of China in 1994, Granted publication number for CN2152688Y China Patent No. (ZL) is: No. 92239061.4 utility model title is the utility model patent of " dust-free black board eraser ", the technical scheme that is adopted, at the technical elements that the sucking chalk powder device is arranged is a routine of great value invention, and it has solved the problem that chalk dust flies upward when using blackboard eraser effectively everywhere.But still have some deficits, it also is difficult to solve simple in structure, easy to use, the problem that pick-up performance is good.
The purpose of this utility model is to provide a kind of Eraser with chalk dust absorbing device.Problem simple in structure to solve, easy to use, that pick-up performance is good.
The purpose of this utility model is achieved in that this utility model Eraser with chalk dust absorbing device.Mainly constitute by baffle plate, netted hair wiping seat, air suction opening, hair wiping, baffle plate, blackboard eraser body, vacuum chamber, moistening sponge ball.Its major part hair is wiped, moistening sponge ball is selected by market, and baffle plate, blackboard eraser body, netted hair are wiped with compression molding of hard plastic material.Baffle plate is connected with the blackboard eraser body with the method for baffle plate with casting, netted hair is wiped seat and is connected with the blackboard eraser body, form vacuum chamber, vacuum chamber is used for collecting chalk dust, peace is shaped on a plurality of moistening sponge balls in inhaling the chamber, moistening sponge ball is used for adsorbing the effect of chalk dust, hair is wiped peace and is wiped on the seat built in netted hair, netted hair wiping seat is gone up peace and is shaped on many air suction openings, the effect of air suction opening is that the chalk dust under being wiped by hair is sucked in the vacuum chamber, by the moistening sponge ball of peace in vacuum chamber chalk dust is adsorbed again.So just realized the purpose of this utility model.
The utility model has the technology of sucking chalk powder device to compare two advantages and improvement with original;
The first, because the utility model has designed baffle plate in technical scheme, after being fallen by the hair erasing, chalk dust enters vacuum chamber so solved.
The second, because having designed netted hair in technical scheme, the utility model wipes seat, can enter vacuum chamber from different positions so solved chalk dust.Thereby just can more effectively solve simple in structure, easy to use, the problem that pick-up performance is good.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1: be whole cross-sectional view of the present utility model:
Fig. 2: be decomposition texture schematic diagram of the present utility model:
The numbering of parts illustrates in the schematic diagram:＜1〉baffle plate＜2〉netted hair wiping seat＜3〉air suction opening＜4〉hair wiping＜5〉baffle plate＜6〉blackboard eraser body＜7〉vacuum chamber＜8〉moistening sponge ball
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, the utility model Eraser with chalk dust absorbing device. Mainly by baffle plate＜1 〉, netted hair rub seat＜2 〉, air suction opening＜3 〉, hair rub＜4, baffle plate＜5, blackboard eraser body＜6, vacuum chamber＜7 〉, moistening sponge ball＜8〉consist of. Baffle plate＜1〉and baffle plate＜5 with method and the blackboard eraser of casting Body＜6〉be connected netted hair rub seat＜2 with blackboard eraser body＜6 be connected, form vacuum chamber＜7 〉, vacuum chamber＜7〉be used for collecting chalk dust, in vacuum chamber＜7〉in peace be shaped with a plurality of moistening seas Silk tops＜8 〉, moistening sponge ball＜8〉be used for adsorbing the effect of chalk dust, hair rub＜4〉the peace system In netted hair rub seat＜2〉on, netted hair rub seat＜2〉upper peace is shaped with many air suction openings＜3 〉, inhale Dirt hole＜3〉effect be by hair rub＜4 wipe lower chalk dust suction vacuum chamber＜7 in, again By peace built in vacuum chamber＜7 in moistening sponge ball＜8 chalk dust is adsorbed. So just realize The purpose of this utility model. Thereby just can solve simple in structurely, easy to use, pick-up performance is good Good problem.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in use, if with blackboard eraser body＜6〉hair of peace system wipes＜4〉chalk dust is wiped following time, chalk dust is wiped seat＜2 by netted hair〉on air suction opening＜3 enter vacuum chamber＜7 in, moistening sponge ball＜8〉can cling chalk dust, after chalk dust is long-pending full, with clear water from air suction opening＜3 with moistening sponge ball＜8 on chalk dust wash out.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with sponge, blackboard eraser, duroplasts, utilize the basic equipment of general teaching aid processing factory, take compression molding one time, combination is installed and is produced by batch, demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
