Abstract
The utility model relates to a dust removal device, in particular to a blackboard dust removal device. The blackboard dust removal device comprises an induced draught fan, a dust suction cloth bag box and a dust suction tube, wherein the dust suction tube is arranged below a blackboard, and one end of the dust suction tube is connected with the induced draught fan through the dust suction cloth bag box. Compared with the prior art, dust generated in the blackboard wiping process can be sucked in the dust suction cloth bag box through the driving of the induced draught fan.
Description
Technical field
the utility model relates to a kind of dust arrester, particularly a kind of dedusting device for blackboard.
Background technology
in existing teaching, blackboard used is not installed dust arrester, be a teacher in teaching process blackboard wiping or student helped in the process of teacher's blackboard wiping in time break, and chalk dust disorderly flies, and the teacher who attends class in this environment for a long time or student are to healthy totally unfavorable.
Utility model content
goal of the invention of the present utility model is to provide a kind of dedusting device for blackboard that reduces dust pollution.
the utility model adopts following technical scheme:
a dedusting device for blackboard, comprises air-introduced machine, dust suction cloth bag box, and sweep-up pipe, sweep-up pipe is placed in blackboard below, and one end of sweep-up pipe is connected with air-introduced machine by dust suction cloth bag box.
technique scheme, compared with prior art, can suck the dust producing in the process of blackboard wiping in suction method cloth bag box by the drive of air-introduced machine.
preferred version of the present utility model is:
air-introduced machine is placed in outside, classroom.
air-introduced machine is connected with the remote-controlled receiver in classroom, is provided with the remote controller switch matching with remote-controlled receiver on blackboard eraser.
the sweep-up pipe that is positioned at blackboard below is connected with the upper sweep-up pipe that is positioned at blackboard top by triplate line and standpipe; The elongated end of upper sweep-up pipe is closed state, and the position that upper sweep-up pipe is relative with blackboard is provided with second slotted hole isometric with blackboard.
the sweep-up pipe that is positioned at blackboard below is connected with the upper sweep-up pipe that is positioned at blackboard top by triplate line and standpipe; The elongated end of upper sweep-up pipe is closed state, and position that upper sweep-up pipe is relative with blackboard is uniform is provided with several suckers.
the other end of sweep-up pipe is enclosed construction.
the sweep-up pipe position corresponding with blackboard is provided with first slotted hole isometric with blackboard or uniform several suckers.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
fig. 2 is the structural representation of upper sweep-up pipe.
fig. 3 is the structural representation of blackboard eraser.
The specific embodiment
a kind of dedusting device for blackboard, referring to accompanying drawing 1 and accompanying drawing 3, in figure: air-introduced machine 1, classroom body of wall 2, remote-controlled receiver 3, dust suction cloth bag box 4, sweep-up pipe 5, triplate line 6, standpipe 7, blackboard 8, upper sweep-up pipe 9, the second slotted hole 10, remote controller switch 11, blackboard eraser 12.
in the present embodiment, sweep-up pipe 5 is placed in the below of blackboard 8, and one end of sweep-up pipe 5 is connected with air-introduced machine 1 by dust suction cloth bag box 4; The other end of sweep-up pipe 5 is enclosed construction.Sweep-up pipe 5 position corresponding with blackboard 8 is provided with first slotted hole isometric with blackboard 8 (9 structure of the concrete structure of sweep-up pipe 5 and the first slotted hole and the upper sweep-up pipe in Fig. 2 is identical).Or the position corresponding with blackboard 8 at sweep-up pipe 5 is provided with several suckers.
air-introduced machine 1 is placed in the outside of classroom body of wall 2, and blower fan 1 is connected with the remote-controlled receiver 3 in classroom, is provided with the remote controller switch 11 matching with remote-controlled receiver 3 on blackboard eraser 12.
the sweep-up pipe 5 that is positioned at blackboard 8 belows is connected with the upper sweep-up pipe 9 that is positioned at blackboard 8 tops by triplate line 6 and standpipe 7; The elongated end of upper sweep-up pipe 9 is closed state, and the position that upper sweep-up pipe 9 is relative with blackboard 8 is provided with second slotted hole 10 isometric with blackboard 8.Or uniformly in upper sweep-up pipe 9 position relative with blackboard 8 be provided with several suckers, also can realize the object of absorption dust.
when with blackboard eraser 12 blackboard wiping 8 time, press the remote controller switch 11 on blackboard eraser 12, by receiver of remote-control sytem 3, start air-introduced machines 1.At this moment a chalk dust part (chalk dust flying upward) of wiping is siphoned away by upper aspiration channel 9, and the chalk dust that another part falls down is siphoned away by the aspiration channel 5 of blackboard 8 belows.Chalk dust unification is collected in dust suction cloth bag box 4 (periodic cleaning dust suction cloth bag box 4, dust suction cloth bag box 4 is arranged on easy-to-mount place), and air-introduced machine 1 is by outside the wind discharge chamber of filtering.After the complete blackboard 8 of wiping, then press the remote controller switch 11 on blackboard eraser 12, air-introduced machine 1 quits work.
in addition, remote controller switch also can be by one-touch or Switching Two key formula structure, the work of air-introduced machine 1 also can be used time delay mode, and during the remote controller switch 11 on pressing blackboard eraser 12, air-introduced machine 1 time delay a period of time of starting working is closed (such as one minute or other times) automatically; Press again remote controller switch 11 and reopen system.
it is cited that the utility model is not limited to foregoing, also can according to actual needs the surrounding of blackboard 12 be provided with respectively to the aspiration channel 5 of slotted hole or sucker, is considered as equally within protection domain of the present utility model.
