Abstract
The utility model discloses a full automatic blackboard eraser for environmental protection, which can effectively prevent the chalk dust from polluting. The utility model is characterized in that the blackboard eraser forms a semi-closed structure. The utility model is composed of a casing support frame (1), a rolling brush (2), a rolling brush motor, a transmission gear, a circuit (6), and an automatic switch (7), wherein the upper end of the rolling brush (2) is provided with a dust exhausting fan (3), the lower end of the rolling brush is provided with a dust collector (4), and meanwhile, the top and the bottom of the casing support frame (1) are provided with train pulleys which are respectively arranged in train tracks (5) of the top and the bottom of the blackboard, and the pulleys are driven through a train motor and a transmission case. The utility model is an ideal teaching appliance for replacing the traditional blackboard eraser in the modern teaching process.
Description
One, technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of electric dust absorption blackboard eraser.
Two, background technology
Present most school all uses blackboard, chalk as teaching aid, and its advantage is with low cost, and blackboard background color dark is more favourable to protection student's eyesight.Its greatest drawback is exactly that the dust of wiping flies upward everywhere when with blackboard eraser the chalk writing on the blackboard being wiped, and has a strong impact on the cleaning of the healthy and clothing of Faculty and Students.The school that has adopts blank and special-purpose black pen to replace a blackboard, and advantage is thoroughly to solve dust problem, but since at the bottom of the blank with bright, see for a long time to cause visual fatigue, influence student's eyesight, be unfavorable for the large tracts of land popularization.The electric blackboard eraser that a kind of patent No. is ZL200420039232.X is disclosed recently, though can reduce dust really, but still need the manual wiping of teachers and students.
Three, summary of the invention
The purpose of this utility model exactly in order to address the above problem, provides a kind of automatic dust-absorbing blackboard to wipe, and can solve the pollution problem that dust causes preferably.
The technical solution of the utility model is: blackboard eraser is a semi-closed structure, form by outer casing stand, round brush, round brush motor, travelling gear, circuit, autocontrol switch, wherein round brush the axle by bearing fixing in outer casing stand, its end is equipped with travelling gear, mesh with the round brush drive axle of motor, the upper end of round brush is provided with dust exhausting fan, and its lower end is provided with dust catcher; The while outer casing stand also is provided with the driving pulley up and down and places respectively in the blackboard Crane Rail up and down, and this pulley is by driving motor, gearbox transmission; Described round brush motor all is connected with autocontrol switch by the circuit that electronic devices and components are formed with the driving motor.The two ends of getting on the right track are respectively equipped with striking the post of driving contact switch, and the both sides of lower railway are provided with the laying dust box.
The utility model is compared with existing electric blackboard eraser, and is not only simple in structure, cost is low, and is easy to use effective, and owing to adopted the bridge crane structure mode, reduced teacher's working strength, is a kind of desirable teaching appliance.
Four, description of drawings
Accompanying drawing 1 is the utility model structural representation.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Be respectively equipped with the Crane Rail of being made by metal or plastics 5 on the upper and lower wall of blackboard surface, 5 the two ends of getting on the right track are respectively equipped with striking the post of driving contact switch, and the lower railway two ends are provided with laying dust box 8.The axle of blackboard eraser round brush 2 is by metal or plastic production, bar shaped or helical type hairbrush are installed above, its length is determined according to the height of blackboard, the axle of this round brush 2 is fixedly mounted in outer casing stand 1 inner bearing, link to each other with the round brush motor by travelling gear, the upper end of round brush is provided with exhaust fan 3, and the lower end is provided with dust catcher 4.Also be provided with outer cover on the outer casing stand 1, the stickup hairiness of outer casing stand 1 bottom surface is sticking, and makes support 1 leave with the blackboard surface vertical direction or to be close to blackboard surface by circuit and transmission mechanism.Driving pulley on the outer casing stand 1 places respectively in the chute of lower railway 5, is connected with the driving motor by gear, gearbox.Described driving motor is all linked to each other by autocontrol switch 7 by integrated circuit 6 with the round brush motor.
When using the utility model, as long as the work that needs is just finished in the different keys position of pressing on the autocontrol switch 7.In the ordinary course of things, blackboard eraser is in the two ends of blackboard, when needing wiping monoblock blackboard, as long as press the strong and driving key of rotation on the automatic switch 7 simultaneously, blackboard eraser will be wiped clean whole Blackboard eraser from left to right or from right-to-left at the uniform velocity parallel moving, and dust will be collected under the effect of last ventilating fan 3 and lower end dust catcher 4 in the storage dirt bag of dust catcher 4.When it reaches the edge of blackboard, will touch and be arranged on the striking the post on 5 of getting on the right track and be parked in a side of blackboard automatically.Blackboard eraser also can be sent to the low amounts of dust that drops on lower railway 5 in the laying dust box 8 of two ends setting in the process of move left and right simultaneously.If only need a certain section of blackboard wiping, the control support of pressing on the autocontrol switch 7 leaves the on ﹠ off switch of blackboard surface and the key of driving a vehicle, when treating that support 1 drives to target phase, press the control support again and be close to blackboard surface key and round brush rotatable key, the writing on the assigned address on the blackboard can be wiped.
