Abstract
A dust collection blackboard brush comprises a brush body; the brush body is a cuboid-shaped box, and the upper portion of the brush body is open; a supporting net is mounted at the open position, and two sets of bristles are arranged on the supporting net; the two sets of bristles are mounted at the central line of the supporting net in a manner of transverse and vertical perpendicularity; and a dust collection box, dust collection blades for providing negative-pressure airflow and a motor for driving the dust collection blades to rotate are arranged in space between the supporting net and the brush body. A dust discharging door used for pouring out dust and communicated with the interior of the dust collection box is formed in the side wall of the brush body, and a dustproof cover is arranged at the edge of the connected position of the brush body and the supporting net; and the height of the dustproof cover is smaller than that of the bristles, and a switch for controlling the motor is further arranged on the brush body. The dust collection blackboard brush is reasonable in structural design, convenient to use, healthful, sanitary, quite suitable for being used by teaching in a school, and easy to popularize.
Description
Technical field
The present invention relates to a kind of realia, be specially a kind of dust-absorbing blackboard brush.
Background technology
Existing blackboard brush in use, can slowly fall on the ground, and another part directly flies away in atmosphere by the chalk dust of its part brushed off, and the expression of serious harm teachers and students is healthy, and can pollute classroom.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dust-absorbing blackboard brush, can absorb the chalk dust produced when erasing the board, prevent dust from flying, health.
In order to solve the problems of the technologies described above, technical scheme of the present invention 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, supporting network is provided with two groups of bristles, the perpendicular midline being mutually installed vertically on supporting network of these two groups of bristles one horizontal, are 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 is provided with and the ashpit for pouring out dust be communicated with in dust-collecting box; 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, brush body is also provided with the switch for controlling motor.
Described brush body is provided with for being fixed in magnet on blackboard or sucker, takes conveniently, avoids and arbitrarily leave about.
Described brush body is connected with handle, clean hygiene, and the scalable adjustment of the length of handle, be applicable to the people of different height, be a teacher or the height of student is shorter time, 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 present invention, owing to only arranging one horizontal one perpendicular two groups of bristles on supporting network, can leave large-area blank mesh passing through for chalk dust; And bristle is arranged at the centre of supporting network, dust cover is set in the edge of brush body, makes the chalk dust brushed off not easily fall on the ground or fly away in air; Also be provided with dust suction blade and motor by the present invention, produce negative-pressure air-flow by the rotation of blade, make chalk dust can arrive in dust-collecting box quickly through supporting network, pick-up performance is good.The dust collected is poured out by ashpit, easy to operate.
Reasonable in design of the present invention, easy to use, health, is applicable to school instruction and uses, be easy to promote very much.
accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is structural front view of the present invention.
Fig. 2 is top view of the present invention.
Detailed description of the invention
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, supporting network is provided with two groups of bristles 3, the perpendicular midline being mutually installed vertically on supporting network of these two groups of bristles one horizontal, are 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 is provided with and the ashpit 7 for pouring out dust be communicated with in dust-collecting box; 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, brush body 1 is also provided with the switch 9 for controlling motor.Described brush body 1 is provided with for being fixed in magnet on blackboard or sucker.Described brush body 1 is connected with handle, and the scalable adjustment of the length of handle.On described supporting network, the size in hole is 1mm*1mm.
During use, open the switch 9 of motor, then hold handle control brush body and carry out wiping on blackboard, the chalk dust wiped is under the effect of negative-pressure air-flow, and can reach in dust-collecting box quickly through supporting network, wiping is complete, when the dust in dust-collecting box is more, poured out by ashpit.During without blackboard brush, it is fixed on blackboard by magnet or sucker, facilitates take next time.
