Description

Intelligent blackboard eraser

Technical Field

The utility model relates to a teaching equipment field, more specifically, the utility model relates to an intelligence blackboard brush.

Background

The knowledge quantity of high school and university classroom is more and more nowadays, and although teachers already adopt PPT courseware to reduce the writing quantity of partial chalk, in order to make students focus on attention and enable the students to understand thoroughly, the teachers still need to write on the blackboard while talking. The blackboard is easy to write, or a plurality of teachers write large characters, and like the blackboard writing content in the middle area of the blackboard, so that the blackboard is easy to write, and the blackboard is full of writing and cannot be erased in time, which is a problem. The existing electric blackboard brush cannot solve the problem of dust emission, cannot specifically clean a certain fixed area of the blackboard, and is inconvenient to use.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art's is not enough, provides an intelligence blackboard brush to expect can solve the big, awkward problem of current blackboard brush raise dust problem.

In order to solve the technical problem, the utility model adopts the following technical scheme:

an intelligent blackboard eraser is installed on one side of a blackboard and comprises a conveying system, an electric push rod, a blackboard eraser and a miniature exhaust fan, wherein the conveying system consists of a conveying belt, a rotating wheel and a first motor; the blackboard eraser is characterized by comprising a shell and wiping flannelette, wherein an exhaust port is formed in the upper surface of the shell, filter cloth is installed at the exhaust port, the wiping flannelette is fixed below the shell, an installation space is reserved between the shell and the wiping flannelette, a miniature exhaust fan is fixed in the installation space, a dust absorption hole is formed in the middle of the wiping flannelette, an air flow channel is formed between the dust absorption hole and the exhaust port, power wires of the miniature exhaust fan and an electric push rod extend to one corner of the back of the blackboard and are stored through a reel, and the reel is driven to rotate by a second motor; the first motor, the second motor, the electric push rod and the miniature exhaust fan are respectively in signal connection with the infrared remote controller.

The technical scheme is that the intelligent blackboard eraser is applied to an integrated single-layer blackboard, and the transmission system and the blackboard eraser are arranged on any one side of the single-layer blackboard.

Another kind of technical scheme is, intelligence blackboard brush use on split type multilayer blackboard, transmission system and blackboard brush setting are in the left side or the downside of this split type multilayer blackboard, electric putter leans on the inboard of wall still to have one just to the flexible second telescopic link of wall, makes the blackboard brush press close to upper blackboard when this second telescopic link is extended, makes the blackboard brush press close to lower floor's blackboard when shortening. When the intelligent blackboard brush is applied to the double-layer blackboard which slides up and down, the electromagnetic lock is installed on the blackboard at the moment, and the electromagnetic lock is locked when the double-layer blackboard slides up and down to the maximum writing area, and is in signal connection with the infrared remote controller. The conveying system is located on the left side of the blackboard and packaged through the shell, the conveying system drives the electric push rod and the blackboard eraser to move up and down, and the electric push rod drives the blackboard eraser to move left and right, so that the blackboard can be wiped in all directions. Because the upper layer blackboard and the lower layer blackboard are not on the same plane after being unfolded, a step is arranged at the joint of the two layers of blackboards, and the step can be spanned by the blackboard eraser by utilizing the telescopic function of the second telescopic rod close to the wall.

When the intelligent blackboard brush is applied to the multilayer blackboard capable of sliding left and right, the electromagnetic lock is also installed on the blackboard at the moment, the adjacent two layers of blackboards are locked by the electromagnetic lock when sliding left and right to the maximum writing area, and the electromagnetic lock is in signal connection with the infrared remote controller. The conveying system is located on the lower side of the blackboard and packaged through the shell, the conveying system drives the electric push rod and the blackboard eraser to move left and right, and the electric push rod drives the blackboard eraser to move up and down, so that the blackboard can be wiped in all directions. Similarly, because the upper layer blackboard and the lower layer blackboard are not on the same plane after being unfolded, a step is arranged at the joint of the two layers of blackboards, and the step can be spanned by the blackboard eraser by utilizing the telescopic function of the second telescopic rod close to the wall.

One side of the shell of the blackboard brush can be opened to discharge chalk dust in the blackboard brush.

The cleaning lint and the blackboard eraser shell are detachably mounted, so that the cleaning lint can be replaced, different cleaning lint can be selected according to different chalk materials, and clean lint can be replaced after the lint is dirty.

The electric push rod can extend and shorten, and the blackboard brush is fixed at the tail end of the first telescopic rod and moves up and down or left and right along with the blackboard brush. When the electric push rod is arranged on the left side of the blackboard, the first telescopic rod can stretch left and right to drive the blackboard eraser to clean the blackboard left and right, and the conveying system is matched to drive the blackboard eraser to move up and down, so that the blackboard can be cleaned up and down, left and right in all directions; when the electric push rod is arranged on the lower side of the blackboard, the first telescopic rod can stretch up and down to drive the blackboard eraser to wipe the blackboard up and down, the conveying system is matched to drive the blackboard eraser to move left and right, and the blackboard can be wiped in an all-around manner up and down. No matter electric putter sets up the left side or the downside at the blackboard, when using intelligent blackboard brush on the multilayer blackboard, its one side that leans on the wall still has the second telescopic link, this electric putter has two telescopic links promptly, the position of first telescopic link adjustment blackboard brush on the blackboard realizes all-round wiping, the second telescopic link is through the distance of adjustment blackboard brush and wall, the surface that can press close to the upper blackboard when making the blackboard brush be located the upper blackboard wipes, also can press close to the surface of lower floor's blackboard and wipe when the blackboard brush is located the lower floor's blackboard. Set up the distance between inductor response blackboard surface and the wall beside electric putter, can control the real-time extension of second telescopic link and shorten more intelligently. Or a button for wiping the lower layer blackboard or the upper layer blackboard is directly arranged on the infrared remote controller, so that the second telescopic rod can be extended or shortened according to the requirement.

Compared with the prior art, the utility model discloses following beneficial effect has at least: the blackboard brush can be applied to an integrated single-layer blackboard and can also be applied to a multi-layer blackboard which slides up and down or left and right, a certain area of the blackboard can be wiped in a targeted manner, raised dust is reduced, a remote control technology is adopted, and the blackboard brush is convenient to use.
