Abstract
Remote controlled electric goes up and down to clean automatically dust free blackboard relates to the blackboard. The utility model provides an it is highly fixed to overcome the existence of traditional blackboard, writes inconvenience from top to bottom, the blackboard eraser is not handy, and the arm is felt very tried when wiping, the dust flew upward when the blackboard was cleaned, made teachers and students' health receive the remote controlled electric goes up and down to clean automatically dust free blackboard of the shortcoming of the injury of chalk dust. Including the soft blackboard of magnetism, still include dwang, lower dwang, servomotor, remote switch, remote control receiving circuit, water receptacle, rivers control switch and rag, the soft blackboard of magnetism is installed on last dwang and lower dwang, goes up the dwang and passes through the bearing installation with dwang down, goes up dwang left end and servomotor output shaft, and on servomotor was located to the remote control receiving circuit, remote switch and remote control receiving circuit wireless connectivity, rag located the soft blackboard rear of magnetism, and the soft blackboard rear of magnetism is located to the water receptacle, and the water receptacle export is connected with the rag through rivers control switch and logical pipe.
Description
Technical field
The utility model relates to blackboard, especially relates to a kind of remote control electric lifting automatic erasing dust-free blackboard.
Background technology
The basic function of blackboard is the word that writes with chalk, and font erasing blackboard eraser is manually wiped.Due to simple and practical, current most blackboard is still adopted in this way.When needing to use multimedia projection education, then put down curtain at the half place of blackboard.But chalk writes has chalk dust unavoidably, wipe writing spended time again, put down curtain at the half place of blackboard and decrease and write space.Some patented technology has also been done some and has been improved, and adopt DC motor Driver electric cleaning blackboard, but wiping arrangement is in front, still has ash to rise unavoidably; Some adopts sliding blackboard to ensure blackboard writing space, and not only mechanism is complicated, and floor space increases; Some clear-cut magnet board, easily wipes that it is pollution-free, but when magnetic sheet is vertical, effect is bad, and word is too light does not see.For this reason, we devise a kind of remote control electric lifting automatic erasing dust-free blackboard device, at demonstration mini Mod or material object, or comment when saying operation and show by projection, be suitable for common classroom instruction, be more suitable for Mobile Teaching system.
Summary of the invention
The purpose of this utility model is that providing one can overcome traditional blackboard exists highly fixing, writes inconvenience up and down; Blackboard eraser is not handy, and when wiping, arm is felt very tried; During blackboard-cleaning, dust flies upward, and makes teachers and students' health be subject to the remote control electric lifting automatic erasing dust-free blackboard of the shortcoming of the injury of chalk dust.
The utility model comprises magnetic soft blackboard, also comprises dwang, lower dwang, servomotor, remote control switch, remote-control receiving circuit, water receptacle, flow control switch and rag;
Magnetic soft blackboard is arranged on dwang and lower dwang, upper dwang and lower dwang are installed by bearing, upper dwang left end is connected with servomotor output shaft, remote-control receiving circuit is located on servomotor, remote control switch is connected with remote-control receiving circuit wireless signal, magnetic soft blackboard rear is located at by rag, and magnetic soft blackboard rear is located at by water receptacle, and water receptacle is exported through flow control switch and is connected with rag by water pipe.
Described rag can be sponge cloth.
Described remote control switch is preferably hand-held remote control switch.
Described water receptacle can be kettle or water bottle etc.
Compared with the prior art, the utility model tool has the following advantages:
By remote control switch, can control machine operation, can realize magnetic soft blackboard electric up-down, when magnetic soft blackboard goes to back, rag can Automatic erasing blackboard, and it is time saving and energy saving to have, the feature of high-efficiency environment friendly.Control by flow control switch the speed that water receptacle flows to the water of sponge cloth, the moistening degree that rag is suitable can be kept.The utility model can be used for the transformation of current classroom blackboard.
The utility model is not only suitable for common classroom instruction in addition, is more suitable for Mobile Teaching system.Adopt the solar energy outside classroom to generate electricity, be supplied to driven blackboard lifting by accumulators store electric energy and use, green energy conservation more; Remote control switch and laser pointer (pen) carry out the imagination combined: the rise and fall of hand-held remote control switch control rule blackboard, eliminate and go to the floatless switch time there at every turn, and position given directions by recycling laser pen, more convenient and practical;
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of the utility model embodiment.
