Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of remote control dust absorption blackboard eraser.
Background technology
In school, teacher attend class every day all will on blackboard writing on the blackboard content, writing not and wipe with blackboard eraser, is all by manually operating at present, and in blackboard eraser erase process, chalk foam flies upward, harm teacher and the health of student.And occupying the time of attending class, according to country about the display of report statistics data: the teachers and students of China, every year because the chalk dust sucked of attending class is about 200g/ people, suffer from the about 20%/year of respiratory tract, PUD D, cancer.As can be seen here, chalk dust is very large to the health hazard of teachers and students.The chalk dust simultaneously flown upward pollutes very large to the personal hygiene of teachers and students, the chalk dust as flown upward makes the collar of teachers and students, cuff, hair, that annoying shade that all be unable to do without it with it.
Application number disclosed in 16 days June in 2010 is the Chinese invention patent application of 200810159660.9, the name of its innovation and creation is called " electric blackboard eraser ", it is made up of sliding bar, bristle, remote controller three part, sliding bar has fixing button, by it, sliding bar is fixed on the upper and lower of blackboard.Bristle there is slip collar, can be horizontally slipped on sliding bar by its bristle, bristle is also provided with inductor, receive the signal from remote controller, movable about ordering about bristle.The present invention is easy to use, has both saved the instructional blocks of time of teacher, has in turn saved strength, meanwhile, decreases the pollution to teacher.
But above-mentioned patent application, still also exists following deficiency:
1. above-mentioned electric blackboard eraser address only the problem of straighforward operation, although can to a certain extent, reduce the suction of dust, dust still flies away everywhere in classroom, still can absorb in human body or fly upward on clothes.
2., because sliding bar is arranged on the upper and lower of blackboard, bristle is in the process of horizontally slipping, and the space of a whole page word erasing that may will not need to wipe, causes new puzzlement.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provides a kind of remote control dust absorption blackboard eraser, and the dust that bristle is wiped can carry out absorbing row relax of going forward side by side fast by this remote control dust absorption blackboard eraser, avoids it to wave in classroom everywhere.
The application also provides a kind of remote control dust absorption blackboard eraser, and this remote control dust absorption blackboard eraser can wipe the word of any space of a whole page arbitrary height, uses more flexible, convenient.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of remote control dust absorption blackboard eraser, comprises remote controller and the electric sliding rail being arranged at the blackboard left and right sides; Each electric sliding rail all slides and is provided with a telescope support, the top of two telescope supports is fixedly connected with the cross bar of a hollow, cross bar is set with the sleeve that several can rotate, the side of each sleeve is provided with bristle and suction nozzle, and the opposite side of each sleeve is provided with steam vent; Screen pack, electro-motor, draught fan impeller, adsorbing powder dust layer and steam vent is disposed with in the hollow reservoir of cross bar.
Described adsorbing powder dust layer is active carbon layer.
Described sleeve has two at least.
Described sleeve has 3.
Described sleeve has 4.
After the utility model adopts said structure, there is following beneficial effect:
1. the setting of above-mentioned electro-motor, draught fan impeller, can absorb the dust that bristle is wiped fast in the cross bar as hollow, and carries out adsorption treatment fast by adsorbing powder dust layer, thus dust can be avoided everywhere to wave in classroom.
2. the setting of the above-mentioned sleeve that several can rotate, makes the bristle be arranged on sleeve to rotate as required, thus can wipe the word of any space of a whole page arbitrary height, uses more flexible, convenient.The setting of remote controller and electric sliding rail etc., makes the remote control blackboard eraser of the application, can operate by long-distance remote control, further reduces the soakage of dust, thus effectively ensure that the health of teachers and students.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of remote control dust absorption blackboard eraser of the utility model;
Fig. 2 shows the cross sectional representation of each sleeve and cross bar in Fig. 1.
Wherein have: 1. electric sliding rail; 2. telescope support; 3. cross bar; 4. sleeve; 5. bristle; 6. suction nozzle; 7. electro-motor; 8. draught fan impeller; 9. adsorbing powder dust layer; 10. steam vent; 11. remote controllers; 12. screen packs.
Detailed description of the invention
Below in conjunction with accompanying drawing and concrete better embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of remote control dust absorption blackboard eraser, comprises remote controller 11 and the electric sliding rail 1 being arranged at the blackboard left and right sides.Each electric sliding rail 1 all slides and is provided with a telescope support 2.
The top of two telescope supports 2 is fixedly connected with the cross bar 3 of a hollow, cross bar 3 is set with the sleeve 4 that several can rotate.The quantity of sleeve 4 has two at least, can be 3, also can be 4.Concrete needs design according to the width of blackboard and the custom of user.
The side of each sleeve 4 is provided with bristle 5 and suction nozzle 6, and the opposite side of each sleeve 4 is provided with steam vent 10.Each sleeve 10 is provided with as the inductor described in background technology, the remote signal of remote controller 11 can be received.
Screen pack 12, electro-motor 7, draught fan impeller 8, adsorbing powder dust layer 9 and steam vent 10 is disposed with in the hollow reservoir of cross bar 3.
Above-mentioned adsorbing powder dust layer 9 is preferably active carbon layer.
Using method is as follows:
1. sleeve 4 rotates: the space of a whole page wiped as required, remote controller 11, telescope support 2 is extended, by with do not need to wipe sleeve corresponding to the space of a whole page 4 and rotate an angle, as 90 ° or 180 °, then telescope support 2 shrinks, the bristle of non-turnbarrel 4 just in time with space of a whole page good contact to be erased.Therefore the word of any space of a whole page arbitrary height can be wiped, use more flexible, convenient.
2. word erasing and dust suction: while the bristle and space of a whole page good contact to be erased of non-turnbarrel 4, suction nozzle 6 on non-turnbarrel 4 and the screen pack 12 in cross bar 3, draught fan impeller 8 are corresponding, and the steam vent 10 on non-turnbarrel 4 is corresponding with the steam vent 10 on cross bar 3.During word erasing, electro-motor 7 starts, under the high-speed driving of electro-motor 7, air in draught fan impeller 8 is discharged fast, from suction nozzle 6, constantly supplements new air, so simultaneously, higher pressure reduction is formed with extraneous in cross bar 3, the dust that bristle 5 is wiped will constantly be inhaled in screen pack 12, and carries out adsorption treatment fast by adsorbing powder dust layer 9, thus dust can be avoided everywhere to wave in classroom.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improve and modify and also should be considered as protection domain of the present utility model.
