Abstract
The invention provides a dehumidifying blackboard. The characteristics of the dehumidifying blackboard are shown in the drawing 1, a perspective structural drawing: the dehumidifying blackboard is formed by four parts, namely an electrothermal film device layer 1, a coating surface layer 2, a power switch device 3 and a power plug 4; the coating surface layer 2 is next to the electrothermal film device layer 1; and the coating surface layer 2 on the surface of the blackboard is made of high temperature resistant materials and has bigger area than the electrothermal film device layer 1. The electrothermal film device layer 1 is arranged on the back of the coating surface layer 2, when the surface of the blackboard is subjected to humidity and fog, the blackboard can be connected with the power by the power plug 4 to enable the electrothermal film device layer 1 to generate heat and conduct the heat to the coating surface layer 2, thus achieving the aim of quick dehumidification, and the blackboard can be turned off by operating the power switch device or unplugging the power plug when the blackboard is not used. The scheme can achieve creation and improvement of the dehumidifying blackboard.
Description
Technical field
the present invention relates to science and education articles for use field, are specifically related to a kind of dehumidifying blackboard.
Background technology
The used blackboard of
school is general only for writing letter written with chalk, does not still have other transformations on the function.Running into the wet weather melena can be moist, uses very inconvenience, needs after blackboard is too dirty to clean, and is not easy to do very puzzlement after worrying again to clean.
The skill summary of the invention
dehumidifying blackboard of the present invention can be removed moist puzzlement rapidly, and serviceability is more convenient.
art scheme is: the dehumidifying blackboard, and its characteristic is as shown in Figure 1, and totally 4 parts are formed, and wherein 1 is Electric radiant Heating Film device layer, and 2 is the coating top layer, and 3 is power switch device, and 4 is attaching plug.Composition through these 4 parts such as the structure that Fig. 1 painted can be realized creation of the present invention and improvement.
Fig. 1 is a structural representation of the present invention.
Fig. 1:
1-Electric radiant Heating Film device layer
2-coating top layer
The 3-power switch device
The 4-attaching plug
Embodiment:
blackboard surface is the high-temperature resistant coating top layer, and the back side, top layer is provided with Electric radiant Heating Film device layer, thereby utilizing power supply that Electric radiant Heating Film device layer is generated heat to conduct to the high-temperature resistant coating top layer reaches the dehumidifying purpose.
The specific embodiment:
The coating top layer 2 on
blackboard surface is the high-temperature resistant coating top layer; The back side, top layer is provided with Electric radiant Heating Film device layer 1; Thereby utilizing power supply that Electric radiant Heating Film device layer is generated heat to conduct to high-temperature resistant coating top layer 2 reaches the dehumidifying purpose, and power switch device 3 capable of using is controlled or utilized attaching plug to control when using or not using.
form of the present invention and the scope of application are not limited to this case diagram and embodiment, and any unit or individual are the suitable variation or the modification of the similar thinking of production or business purpose to it, all will be regarded as the enforcement to patent of the present invention.
Claims (2)
1. the coating top layer is a high-temperature resistant coating.
2. the back side, coating top layer is provided with the Electric radiant Heating Film device.
