Abstract

The utility model relates to a novel automatic blackboard eraser which comprises a rolling shaft, dust absorption wiping cloth, sliding rails, an idler wheel support, travel switches, a switch and a dust collecting barrel, wherein the parallel sliding rails are fixed at the upper end and the lower end of a blackboard, the dust absorption wiping cloth is adhered to the whole outer surface of the rolling shaft, two ends of the rolling shaft are fixedly connected with the idler wheel support, conical grooves formed in idler wheels are embedded in the sliding rails, the travel switches are fixed at two ends of the sliding rails respectively, the idler wheels and the rolling shaft are driven by a motor to move back and forth along the sliding rails, and the purpose that the blackboard can be wiped automatically and cleanly is achieved. At the same time, an annular gap is arranged inside the dust absorption cloth along the axial direction, and dust discharging holes are formed at the bottom end of the dust absorption cloth and are connected with the dust collecting barrel through a flexible pipe. In the process of wiping of the blackboard, dust can fall into the annular gap through dense fine holes in the dust absorption cloth, the dust is removed and collected in the dust collection barrel through the dust discharging holes, and the occurrences that the dust flies all around, the classroom environment is polluted and the dust does harm to the health of teachers and students in the process of wiping of the blackboard are effectively avoided.

Description

A kind of new type auto blackboard eraser

Technical field

The utility model has related to a kind of cleaning appliance, has especially related to a kind of new type auto blackboard eraser.

Background technology

Existing blackboard eraser is made up of dust suction cloth and fixed bin, because the dust removal ability of dust suction cloth is limited, after long-time the use, tend to the long-pending full thick chalk powder of one deck on the dust suction cloth, the user tends to knock gently in the corner of blackboard, makes the chalk powder abate on the blackboard eraser, and dust flies upward everywhere in the classroom at this moment, have a strong impact on the healthy of teacher and student, and use inconvenience.

The utility model content

The purpose of this utility model is at the deficiencies in the prior art, and a kind of new type auto blackboard eraser is provided, and is simple in structure, need not the user erase the board in person, only the need Push switch can be automatically with the blackboard wiped clean, simultaneously, avoided dust to fly upward everywhere, the classroom environment that keeps clean.

The technology solution that the utility model adopts is as follows:

A kind of new type auto blackboard eraser, comprise roller bearing, dust suction wiper, slide rail, rolling wheel support, travel switch, switch, dust bucket, parallel sliding track is fixed on the two ends up and down of blackboard, the whole outer surface of roller bearing adheres to the dust suction wiper, the inside at the two ends up and down of roller bearing is respectively equipped with motor, fixedlys connected with rolling wheel support respectively in the outside at the two ends up and down of roller bearing; The two ends of rolling wheel support fixedly have roller respectively, are positioned at the roller of slide rail outside one side and motor and fix and place on the slide rail, and travel switch is separately fixed at the two ends of slide rail.

Described dust suction wiper inside is provided with the space of annular vertically, and the bottom is provided with dust exhausting hole, and dust exhausting hole is connected with dust bucket by flexible pipe, and chalk dust, health environment-friendly were removed in the limit when realization limit erased the board.

Describedly be provided with cone tank along the roller outer surface profile, cone tank is embedded on the slide rail.

Described switch is connected with motor in the roller bearing by the motor on electric wire and the roller, and switch is fixed on the side of blackboard frame.

The beneficial effects of the utility model are:

The utility model is in the process that erases the board, and dust falls in the space of annular by the intensive pore on the dust suction wiper, is scavenged in the dust bucket by dust exhausting hole, effectively avoided when blackboard wiping, dust flies upward everywhere, pollutes classroom environment, healthy unfavorable to teacher and student.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing;

Fig. 1 is the structural representation of a kind of new type auto blackboard eraser of the utility model;

Fig. 2 is the structural representation of blackboard eraser;

Fig. 3 is the structural representation of roller.

The specific embodiment

With reference to accompanying drawing 1 and Fig. 2, a kind of new type auto blackboard eraser, comprise roller bearing 1, dust suction wiper 11, slide rail 21, rolling wheel support 3, travel switch 22, switch 23 and dust bucket 4, fixedly there is parallel sliding track 21 at the two ends up and down of described blackboard 2, the whole outer surface of described roller bearing 1 adheres to dust suction wiper 11, the inside at two ends is respectively equipped with motor 12 up and down, fixedlys connected with rolling wheel support 3 respectively in the outside; Described dust suction wiper 11 inside are provided with the space 13 of annular vertically, the bottom is provided with dust exhausting hole 14, dust exhausting hole 14 is connected with dust bucket 4 by flexible pipe 41, in the process that erases the board, dust falls into 13 li in annular space by the intensive pore on the dust suction wiper 11, is discharged to 4 li of dust buckets by dust exhausting hole 14, effectively avoided when blackboard wiping, dust flies upward everywhere, pollutes classroom environment, healthy unfavorable to teacher and student.

With reference to accompanying drawing 3, the two ends of described rolling wheel support 3 fixedly have roller 31 respectively, be provided with cone tank 33 along roller 31 outer surface profiles, be embedded on the slide rail 21, the roller 31 that is positioned at slide rail 21 outsides one side is fixing with motor 32, place on the slide rail 21, travel switch 22 is separately fixed at the two ends of slide rail 21, when needing blackboard wiping, open switch 23, motor 32 on the roller 31 drives roller 31 and moves along slide rail 21, the motor 12 of roller bearing 1 inside drives roller bearing 1 circumference that is stained with dust suction wiper 11 and rotates, and when blackboard eraser moves to two ends, runs into travel switch 22, change motor 32 on the roller 31 and the rotation direction of the motor 12 in the roller bearing 1, realize the blackboard eraser blackboard wiping that moves around.

Described switch 23 is connected with motor 12 in the roller bearing 1 by the motor 32 on electric wire and the roller 31, and switch 23 is fixed on the side of blackboard frame 24.
