Abstract
The utility model aims to provide a dust-sucking type eraser, comprising a bid blackboard eraser and a small blackboard eraser. The erasing surface of each blackboard eraser is provided with a dust-sucking groove/hole which is connected with a duster through a dust-sucking pipe and the dust generated in the erasing process can be sucked into the duster through the dust-sucking groove/hole and the dust-sucking pipe to prevent the dust scattering and protect teachers and students and teaching environment. The dust the duster sucks can be recycled and reused with the function of environmental protection and in addition, the small blackboard eraser can flexibly and conveniently erase parts while the big blackboard eraser can erase the whole very quickly to improve efficiency and solve the deficiency that the traditional blackboard eraser can not be easy to erase the higher point of the blackboard.
Description
Technical field
The utility model relates to teaching aid, particularly a kind of wiping arrangement with dust-absorbing function.
Background technology
Traditional blackboard wiper is known ordinary blackboard eraser, in its wiping process, produces a large amount of dust, and the health that promptly endangers teachers and students has been polluted the environment in classroom again.Another shortcoming is that the shorter teachers and students of stature are difficult for wiping the letter written with chalk of eminence.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of wiping arrangement with dust-absorbing function is provided, and has the function of automatic absorption dust, and protection teachers and students' health purifies teaching environment, and is easy to use.
The utility model adopts following technical scheme:
Have the wiping arrangement of dust-absorbing function, comprise blackboard eraser, it is characterized in that: also comprise dust catcher, have dust-absorbing groove/hole on the wiping surface of described blackboard eraser, this groove/hole is communicated with dust catcher by sweep-up pipe.
Also comprise head in two guide rails and can be along the strip blackboard eraser of guide rail movement, two guide rails are arranged in two relative frames of blackboard, have dust-absorbing groove/hole on the wiping surface of this blackboard eraser, and this groove/hole is communicated with dust catcher by sweep-up pipe.
Described blackboard eraser inside has the vacuum chamber that communicates with dust-absorbing groove/hole, and this vacuum chamber communicates with described dust-absorbing groove/hole and is communicated with described sweep-up pipe.
Described sweep-up pipe is scalable.
The interior bottom of described dust catcher is equiped with ash collecting box.
Comprise the hooking device that hangs blackboard eraser.
The utlity model has following advantage:
This device has designed small one and large one two blackboard erasers, and little blackboard eraser is used for local wiping, and is flexible; Big blackboard eraser whole board wiper is fast wiped away, and raises the efficiency, and solves the deficiency that traditional blackboard eraser is difficult for wiping eminence; The wiping surface of blackboard eraser has dust-absorbing groove/hole, and this dust-absorbing groove/hole is communicated with dust catcher by sweep-up pipe, and the dust that produces in the wiping process sucks dust catcher by dust-absorbing groove/hole, sweep-up pipe, has avoided dust to fill the air, protection teachers and students and teaching environment; The dust that dust catcher sucks is recyclable to be utilized again, has environment-friendly function.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1 and Figure 2.Blackboard 1 is installed with upper and lower edge, and upper and lower edge is respectively equipped with guide rail 11,12, and track 12 connects the thickness of lower frame.Wiping mechanism comprises platelet wiping 2 and strip blackboard eraser 3, and blackboard eraser 2 sizes are suitable with known common blackboard eraser; The height of the length of blackboard eraser 3 and blackboard 1 is suitable, and it vertically is arranged between the track 11,12 and the upper end is stretched in the track 11, track 12 is passed in the bottom and extend to outside the track 12, can carry out whole board wiper along the horizontal direction of blackboard 1 and wipe away.The bottom of blackboard 1 is provided with the dust catcher 4 that has two telescopic pipes 5,6, and this dust catcher 4 is movable to be contained in the bottom of blackboard 1 lower frame or to be fixedly mounted on the wall, is connected by sweep-up pipe 5,6 respectively between dust catcher 4 and the blackboard eraser 2,3.The both ends of blackboard 1 lower frame are provided with the hooking device 13 of placing blackboard eraser 2 respectively.
As shown in Figure 3.Dust catcher 4 has two sweep- up pipes 5,6, and bottom is equiped with dismountable ash collecting box 4a in it, and this ash collecting box 4a is used to collect the dust that dust catcher 4 sucks, and is convenient to recycling.
As Fig. 4, shown in Figure 5.Be equiped with many felts 22 on the wiping surface of blackboard eraser 2 shells 21, shell 21 inner hollow form vacuum chamber 24, be provided with dust-absorbing groove 23 between the felt 22 to absorb the dust that falls after the wiping, dust-absorbing groove 23 communicates with vacuum chamber 24, and the bottom of vacuum chamber 24 is provided with the socket part and is communicated to dust catcher with socket sweep-up pipe 5.Above-mentioned felt 22 can change, and after use a period of time, should change old felt to guarantee the wiping function of blackboard eraser.The structure of blackboard eraser 3 is similar to blackboard eraser 2, is not giving unnecessary details at this.
Working method of the present utility model: before the blackboard wiping 1, open dust catcher 4 earlier, because the suction of dust catcher 4 makes dust-absorbing groove 23 produce negative pressure, the chalk dust that falls when blackboard eraser 2 or 3 wipings is sucked by dust-absorbing groove 23, and enter in the dust catcher by vacuum chamber 24, sweep-up pipe 5 or 6, fall into ash collecting box 4a at last, close dust catcher 4 after wiping finishes; After using a period of time, pull down ash collecting box 4a and reclaim chalk dust.Local wiping is wiped 2 with platelet and is carried out wiping, and whole board wiper is wiped away with strip blackboard eraser 3 and carried out wiping.
