Abstract
The invention relates to a dust absorption eraser, comprising dust absorption box, motor, switch, corrugated guide pipe, board eraser, guide rail and sliding wheel, wherein the board eraser is set in parallel guide rails at upper and lower sides of black board and is guided by the sliding wheel. The board eraser is the groove box with corresponding width with black board and multiple felt eraser heads are set in the groove box. Dust discharging holes are set at two sides of felt eraser head. There is spring between bottom seat of said board eraser and felt eraser head so that felt on the board eraser is attached to black board more tightly. Corrugated guide tube is connected above the board eraser and the other end of corrugated guide pipe is connected with dust absorption box. Motor switch is installed on the board eraser and also can be installed on the wall. The dust-absorption black board eraser is provided with simple structure, convenient use and sanitation.
Description
Technical field
The present invention relates to a kind of blackboard eraser, particularly a kind of dust absorption blackboard eraser.
Background technology
When writing with chalk on blackboard, ordinary blackboard eraser very easily makes the chalk bits along with moving of blackboard eraser flown upward with air-flow when wiping the literal that chalk writes, and both contaminated environment was detrimental to health again.Particularly for the teacher of the work of being engaged in teaching for a long time, accumulate over a long period, chalk dust can deposit at respiratory system, causes occupational disease, can cause adverse effect too for the student who is sitting in former rows.Patent 02113410.3 has been announced a kind of negative-pressure black board eraser, by the effect of axial flow blower, dust is taken away from the SS on the blackboard eraser, but this negative-pressure black board eraser do not fix, and volume is bigger, accounts for the bigger position of tool.Patent CN 85 108104A have announced a kind of electric blackboard eraser, also be to adopt motor to take dust away, but its blackboard eraser are to control positive revertive control blackboard eraser by the time relay, does move left and right, and blackboard eraser is clean.
Summary of the invention
The object of the present invention is to provide a kind of dust absorption blackboard eraser of easy to use, environmentally-friendly sanitary.
The objective of the invention is to realize in the following way: a kind of dust absorption blackboard eraser comprises suction box, motor, switch, corrugated conduit, blackboard eraser, guide rail, pulley.Wherein, described blackboard eraser is fixed on blackboard up and down in the parallel guide rail in both sides, and guides by pulley.
Described blackboard eraser is the groove box suitable with the blackboard width, lays the polylith felt in the middle of the groove box and wipes head.It is dust exhausting holes that felt is wiped a both sides.
Described blackboard eraser base and felt are wiped between the head spring, makes that the felt on the blackboard eraser more is adjacent to blackboard.The blackboard eraser top is connected with corrugated conduit, and the other end of corrugated conduit is connected with suction box.
Motor switch is installed on the described blackboard eraser, also can be installed on the wall.
Hygienic advantages simple in structure, easy to use that the present invention has.

Fig. 3 is the A-A profile of blackboard eraser.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
The objective of the invention is to realize in the following way as Fig. 1: a kind of ash-collecting blackboard eraser comprises that suction box 6, motor 7, corrugated conduit 5, blackboard eraser 4, guide rail 1, pulley 3 constitute. Guide rail 1a, 1b are installed both sides up and down at blackboard, two guide rails are parallel, and the two ends of blackboard eraser 4 are equipped with pulley 3, and by the guiding of pulley 3 and guide rail 1, blackboard eraser 4 can stop move left and right in blackboard 2 preceding optional positions, finishes the action that erases the board.
Described blackboard eraser 4 (see figure 2)s are the groove box suitable with the blackboard width, lay Pork-pieces felt in the middle of the groove box and wipe 8, and it is dust exhausting holes 9 that felt is wiped 8 both sides.
Described blackboard eraser base and felt have spring 10 between wiping 8, make that the felt on the blackboard eraser more is adjacent to blackboard 2.Blackboard eraser 4 tops are connected to corrugated conduit 5, and the other end of corrugated conduit 5 is connected with suction box 6.
Motor switch is installed on the described blackboard eraser 4, also can be installed on the wall.
Certainly,, do not spend performing creative labour, on the basis of the foregoing description, can do multiple variation, can realize purpose of the present invention equally for one of ordinary skill in the art.But above-mentioned various variations obviously should be at the protection domain of claim of the present invention.
