CN2445938Y - Dual-purpose automatic blackboard eraser able to sectionally wip and remote control fast dustless noiseless wip - Google Patents

Abstract

The utility model relates to a dual-purpose automatic blackboard eraser which can be used for erasing in sections and can be controlled remotely without dust and noise. The dual-purpose automatic blackboard eraser is characterized in that a bolt and a spring 4 for damping vibration and eliminating noise are arranged between a track 3 and a blackboard frame; an upper box 6 and a lower box 11 are arranged on the track 3, and a wiping roller 9 for erasing chalk writing and a dedusting roller 10 for removing chalk powder on the wiping roller 9 are arranged between the upper box 6 and the lower box 11; a suction cleaner 12 is used for collecting the chalk powder in a dust collecting box 13 for dumping the chalk powder at will. When the utility model is used, an electric button is pushed to start a motor 7, and then the utility model can complete the whole wiping and dedusting procedure automatically. When in a power-off state, a handle can be inserted into an inserting hole 14 of a hand-operated rocking handle for manual drive; a remote controller 15 and a sectional wiping controller 16 ensure that the utility model has a remote control function and a sectional erasing function.

Description

The dual-purpose automatic blackboard eraser of the quick dustless noiselessness of a kind of sectional wiping and remote control,

This practical realia that relates to, specifically a kind of fast automatic blackboard eraser that has dust suction, removes noise.But and add remote controller and segmentation wiping controller long-distance remote control and segmentation wiping.

People usually need to use chalk to write on blackboard and the continuous wiping of needs when teaching.Well-known manually erase the board not only fatigue but also a large amount of holding times of need, and the chalk foam has a strong impact on the classroom health.The technology that the ZL9722705.7 patent provides, the operator need walk about so that can touch the push button that is installed on the device, uses inconvenient.

The purpose of this utility model, just provide a kind of have fast dust suction and noiseless automatic blackboard eraser, within the several seconds, both can finish and be equivalent to manually to use blackboard eraser to wipe the high-quality automatic blackboard wiping articles for use that number picks up time, and the hand-held push button or the backguy push button that can adopt lead to be communicated with, especially add remote controller and segmentation wiping controller, a long way off manipulation device and segmentation wiping, and can regulate wiping speed by electrical motor gearshift, make it to use more convenient.

In order to achieve the above object, the utility model realizes by following scheme, and its design feature is it by track, top box, nowel, wiper rolls, take off dirt roller, outer cover, dust catcher, disposal box, motor, reel and travel switch, remote controller, segmentation wiping controller etc. are formed voluntarily.

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

Fig. 1 is the utility model structural representation.Its 1-is reel voluntarily, the 2-lead, and the 3-track, the 4-spring, the 5-travel switch, the 6-top box, the 7-motor, the 8-outer cover, 9-wiper rolls, 10-take off the dirt roller, 11-nowel, 12-dust catcher, 13-disposal box, the manual rocking handle jack of 14-, 15-remote controller, 16-segmentation wiping controller.

As shown in Figure 1, track of the present utility model can be connected with the blackboard frame with the bolt that has spring 4, the pressure that is produced by spring makes track 3 compress to the blackboard surface direction, thereby make the top box 6 and the nowel 11 that place on the track 3 produce certain pressure, when wiper rolls rotates, blackboard surface is rubbed together with 9 pairs of blackboard surfaces of wiper rolls.Spring 4 also plays damping, the effect that abates the noise.Reel 1 can make motor 7 remain straight with the lead 2 that is connected of power supply voluntarily, be placed in the wiper rolls 9 in the middle of top box 6 and the nowel 11 and take off that dirt roller 10 is driven by motor 7 and fast rotational and along track 3 walkings, the chalk powder that splashes is together with sticking in the chalk powder of taking off on the wiper rolls 9 at any time and be blocked by outer cover 8 by taking off dirt roller 10, outer cover 8 has the foamed plastics thin slice of installing to intercept with the contact site of blackboard surface, the chalk foam can not be overflowed, and the airflow that produces owing to dust catcher 12 extracting airs, flow in the outer cover 8 by outer cover 8 peripheries, the chalk foam is brought in the disposal box 13 along the hole and the pipeline of outer cover 8 lower ends, the chalk foam that puts together can arbitrarily be outwelled, thereby eliminate chalk powder effectively and pollute the classroom, only need press push button during use, can wipe the chalk writing on the blackboard within several seconds, this moment, travel switch 2 was cut off the electricity supply immediately.Handle can be inserted manual rocking handle during power failure and draw together in the hole 14, carry out manual driven.Remote controller 15 and segmentation wiping controller 16 can make that application is more convenient.

The utility model is simple and reasonable for structure, can fast and high quality ground blackboard wiping and dustless, noiselessness, very be fit to the usefulness of teaching.
