Wherein, 1 is drawing board chunk, and 11 is control panel, and 111 is single-chip microcomputer, and 12 is heating resistance wire, and 13 is relay, and 14 is temperature sensor, and 15 is vacuum generator, and 16 is sucker, and 17 is sucker placement hole, and 18 is charactron, and 19 is function button.
Detailed description of the invention
Now with detailed description of the invention, the technical scheme that application claims is protected is described in further detail by reference to the accompanying drawings.
As shown in Figure 1-2, in the present embodiment, drawing board body is consisted of two hinge the drawing board chunk 1 of two pieces of same sizes.Its structure makes two pieces of drawing board chunks 1 mutually fold, and this bulk area of drawing board after folding reduces half, makes it easy to carry and transport.
As shown in Figure 3, in the present embodiment, every block drawing board chunk 1 is built-in with heating resistance wire 12, control panel 11, relay 13, temperature sensor 14, vacuum generator 15, sucker 16 and charactron 18; Drawing board chunk 1 exterior side surface is provided with function button 19 and sucker placement hole 17; Also be fitted with insulating heat-conductive silica gel piece at six inwalls of drawing board chunk 1, for the protection of user, avoid electric shock accidents.
As shown in Figure 4, heating resistance wire 12 is connected with relay 13 and by the On/Off of relay 13 as its switch control rule heating resistance wire 12.Vacuum generator 15 is connected with sucker 16, and its sucker is positioned at sucker 16 central authorities, and sucker 16 part from sucker placement hole 17 stretches out in outside drawing board chunk 1 simultaneously.Control panel 11 is integrated with control module, power module and single-chip microcomputer 111, meanwhile, control panel 11 also connects relay 13, temperature sensor 14, charactron 18, vacuum generator 15 and function button 19 simultaneously.
Wherein, the control of the controlled making sheet 11 of folding of relay 13, and logical control relay 13 folding controls the opening and closing/closedown of heating resistance wire 12; Temperature sensor 14 can respond to the temperature of drawing board chunk 1 inside, and its signal of telecommunication can feed back on control panel 11 and be processed by control panel 11, and meanwhile, the temperature of its induction can be shown by charactron 18; The On/Off of vacuum generator 15 is controlled the control of plate 11 equally; Function button can send various control instruction to control panel 11, in the present embodiment, can be controlled the heating temp of the On/Off of vacuum generator 15, the On/Off of heating resistance wire 12 and setting heating resistance wire 1212 by function button 19.
Drawing board method of work of the present invention is as follows: when user needs to dry drawing paper, the heating temp of heating resistance wire 12 is first set according to actual needs by function button 19, and open the heating, drying function of drawing board, control panel 11 can close by control relay 13 after accepting instruction, thus make heating resistance wire 12 heating power, changed by temperature sensor 14 induction monitoring drawing board internal temperature, its temperature sensed is shown by charactron 18, and the heat having heating resistance wire 12 to send finally can pass to the pigment of drawing paper drying on drawing paper.When the temperature that temperature sensor 14 senses has reached maximum design temperature, relay 13 can cut off by control panel 11, thus heating resistance wire 12 is quit work allow naturally cooling of drawing board, when the temperature that temperature sensor 14 senses drops to minimum design temperature, relay 13 can close by control panel 11, heating resistance wire 12 being generated heat again, making drawing board when carrying out heating, drying by repeatedly performing above step, its temperature keeps within the specific limits, avoids too high or too low for temperature.
When user needs drawing paper is air-dry, vacuum generator 15 is started by function button 19, and Portable fan being placed on the Pan Kou of sucker 16, sucker 16 firmly can hold Portable fan under the cooperation of vacuum generator 15 makes it be fixed on drawing board sidepiece, carries out air-dry by Portable fan to drawing paper.
The embodiment of the above is only the preferred embodiment of the present invention, not limits practical range of the present invention with this, therefore the change that all shapes according to the present invention, principle are done, all should be encompassed in protection scope of the present invention.
