Description
Technical field
The utility model relates to a kind of realia, is specially a kind of dust-absorbing blackboard brush.
Background technology
Existing blackboard brush in use, can slowly fall on the ground by the chalk dust of its part brushing off, and another part directly flies away in air, serious harm teachers and students' expression health, and can pollute classroom.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of dust-absorbing blackboard brush, can absorb the chalk dust producing while erasing the board, prevents dust from flying, health.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of dust-absorbing blackboard brush, comprise brush body, described brush body is a rectangular-shaped box, opened upper end, unlimited place is provided with supporting network, and two groups of bristles are installed on supporting network, this two groups of bristles one horizontal one perpendicular mutual at right angle setting is in the midline of supporting network, is provided with dust-collecting box, for providing the dust suction blade of negative-pressure air-flow and for driving the motor of dust suction blade rotation in the space between supporting network and brush body; Described brush body sidewall be provided with in dust-collecting box, be communicated with for pouring out the ashpit of dust; The edge that described brush body is connected with supporting network is provided with dust cover, and the height of dust cover, lower than the height of bristle, is also provided with the switch for controlling motor on brush body.
Described brush body is provided with for being fixed in magnet or the sucker on blackboard, takes conveniently, has avoided arbitrarily leaving about.
On described brush body, be connected with handle, clean hygiene, and the scalable adjusting of the length of handle, be applicable to the people of different heights, be a teacher or when student's height is shorter, the length of handle can be extended, each corner on blackboard can be brushed, reasonable in design.
On described supporting network, the size in hole is 1mm*1mm, facilitates passing through of dust.
The utility model, due to one horizontal one perpendicular two groups of bristles being only set on supporting network, can leave large-area blank mesh passing through for chalk dust; And bristle is arranged to the centre of supporting network, in the edge of brush body, dust cover is set, make the chalk dust brushing off be difficult for falling on the ground or fly away in air; Also be provided with dust suction blade and motor by the utility model, produce negative-pressure air-flow by the rotation of blade, chalk dust can be arrived in dust-collecting box by supporting network fast, pick-up performance is good.The dust of collecting is poured out by ashpit, easy to operate.
Reasonable in design of the present utility model, easy to use, health is applicable to school instruction and uses very much, is easy to promote.
accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural front view of the present utility model.
Fig. 2 is top view of the present utility model.
The specific embodiment
As shown in Figure 1-2, a kind of dust-absorbing blackboard brush, comprise brush body 1, described brush body 1 is a rectangular-shaped box, opened upper end, unlimited place is provided with supporting network 2, and two groups of bristles 3 are installed on supporting network, this two groups of bristles one horizontal one perpendicular mutual at right angle setting is in the midline of supporting network, is provided with dust-collecting box 4, for providing the dust suction blade 5 of negative-pressure air-flow and for driving the motor 6 of dust suction blade rotation in the space between supporting network and brush body 1; Described brush body 1 sidewall be provided with in dust-collecting box, be communicated with for pouring out the ashpit 7 of dust; The edge that described brush body is connected with supporting network is provided with dust cover 8, and the height of dust cover, lower than the height of bristle, is also provided with the switch 9 for controlling motor on brush body 1.Described brush body 1 is provided with for being fixed in magnet or the sucker on blackboard.On described brush body 1, be connected with handle, and the scalable adjusting of the length of handle.On described supporting network, the size in hole is 1mm*1mm.
When use, open the switch 9 of motor, then hold handle control brush body and on blackboard, carry out wiping, the chalk dust of wiping, under the effect of negative-pressure air-flow, can reach in dust-collecting box by supporting network fast, and wiping is complete, in the time that the dust in dust-collecting box is more, pour out by ashpit.During without blackboard brush, it is fixed on blackboard by magnet or sucker, facilitates take next time.
