It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of description the invention and simplifies description, rather than indicate
Or imply that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot understand
For the limitation to the invention.
In addition, term " first ", " second ", " third " etc. are used for description purposes only, it is not understood to indicate or imply
Relative importance or the quantity for implicitly indicating indicated technical characteristic.The feature of " first ", " second " etc. is defined as a result,
It can explicitly or implicitly include one or more of the features.In the description of the invention, unless otherwise indicated,
The meaning of " plurality " is two or more.
Term " installation ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, be also possible to removable
Connection is unloaded, or is integrally connected；It can be mechanical connection, be also possible to be electrically connected；It can be directly connected, it can also be in
Between medium be indirectly connected, can be the connection inside two elements.For the ordinary skill in the art, can pass through
Concrete condition understands concrete meaning of the above-mentioned term in the invention.
In order to solve the problems, such as blackboard-cleaning manual operation low efficiency existing in the prior art, as depicted in figs. 1 and 2,
The present embodiment provides a kind of self-cleaning formula blackboards, including blackboard 1, the cleaning mechanism being arranged on blackboard 1 and start stop switch 14, clearly
Reason mechanism includes that the first motor 2 at 1 top of blackboard is arranged in, and the output shaft of first motor 2 is connect with horizontally disposed shaft 3,
Drive bevel gear 8 there are two being arranged in shaft 3；The two sides of blackboard 1 are vertically arranged with lead screw 4 respectively, the top of lead screw 4 be equipped with from
