Abstract
The invention discloses a quick-drying water drawing board with a PTC heating film. The board comprises a drawing board frame, a bottom board of the drawing board frame is fixedly provided with the flexible PTC heating film, a substrate is arranged on the flexible PTC heating film, a water absorbing writing layer is arranged on the substrate and arranged on the upper surface of the substrate, the substrate is made of non-woven cloth, and the water absorbing writing layer is a composite film layer formed through epoxy resin, polystyrene and silicon dioxide. According to the water drawing board, a traditional water drawing board is combined with the PTC heating film, so that on the premise that safe use is guaranteed, drying speed of the water drawing board after being used is greatly increased, and people can use the water drawing board again in a short time and do not need to wait.
Description
Technical field
The present invention relates to a kind of water-writing plate, be specially a kind of fast solid carbon dioxide drawing board of the PTC of application heating film.
Background technology
On market, the kind of Drawing board for children is a lot, has common drawing board, magnet drawing board, water-writing plate etc.Common drawing board is generally the drawing of writing on drawing board with coloured art pen, then can wipe, but coloured art pen is unhygienic, also than being easier to, clothes etc. is made dirty; Magnetic drawing is that the effect by magnet drinks up metal iron powder can form writing, but writing can be not clear, and the iron powder of the drawing board words the inside of having broken is out very dangerous to children; Now on market out a lot of water-writing plates, on drawing board, to be provided with one deck water to write cloth, it is after water writing paper that water is write cloth, on 2011 end of the year markets, new development is got up take nonwoven as material, process through special process, can be with water for China ink, paste for the durable writing brush of the paper effect cloth of practising handwriting with cloth, claim again ten thousand water to write cloth, exempt from ink and write cloth etc.Be characterized in: when writing brush dips in clear water and writes, can manifest with China ink and write on the effect on rice paper on cloth, after water is dry, recover again new cloth as before, be that domestic advanced person, popular, environmental protection, efficient senior writing brush practise handwriting for paper stationery; With water-color paintbrush, write, water stain staying just had writing on cloth, water has been done afterwards reusable again, very convenient and safe and sanitary, but wait water to write water stain dry also the needs quite for a long time on cloth, generally want 5,10 minutes, within minimum 10 minutes, can be just above that water is write cloth and recovered initial clean, so children's interesting drawing a picture when writing just often, water be write cloth and is drawn full, having to wait long time and just can continue to write picture, is very inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of fast solid carbon dioxide drawing board of the PTC of application heating film, by the characteristic of flexible PCT heating film automatic constant-temperature-heating, can be by the moisture flash baking on water-writing plate surface, to write next time after use at water-writing plate.
For reaching this object, the present invention by the following technical solutions:
A kind of fast solid carbon dioxide drawing board of applying PTC heating film, comprise palette rack, on the base plate of palette rack, be fixed with flexible PCT heating film, on flexible PCT heating film, be provided with a basic unit, in basic unit, be provided with water suction writing layer, described water suction writing layer is sprayed on basic unit's upper surface, wherein, basic unit adopts nonwoven, and water suction writing layer is the composite film that epoxy resin, polystyrene and silica form; Described flexible PCT heating film comprises silica gel outer, some groups of PTC ceramic thermistor core sheets and aluminium strip, PTC ceramic thermistor core sheet and aluminium strip are installed in described silica gel outer, aluminium strip is placed in the both sides of PTC ceramic thermistor core sheet, aluminium strip contacts completely with silica gel outer, aluminium strip is connected by conducting resinl with PTC ceramic thermistor core sheet, and PTC ceramic thermistor core sheet and aluminium strip are placed in silica gel outer.
Further, in described palette rack one side, be provided with the supply unit into the power supply of flexible PCT heating film.
Further, described PTC ceramic thermistor core sheet is rectangle or circle.
Beneficial effect of the present invention is: the present invention adopts traditional water-writing plate is combined with PTC heating film, guaranteeing under the prerequisite of safe handling, improved greatly water-writing plate in use dry speed afterwards, made people just can reuse water-writing plate in a short period of time, without wait.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 be in the present invention flexible PCT heating film dissect structural representation.
In figure: 1, flexible PCT heating film; 1a, aluminium strip; 1b, PTC ceramic thermistor core sheet; 1c, silica gel outer; 2, palette rack; 3, basic unit; 4, water suction writing layer; 5, supply unit.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate technical scheme of the present invention.
A kind of fast solid carbon dioxide drawing board of applying PTC heating film as shown in Figure 1 and Figure 2, comprise palette rack 2, on the base plate of palette rack 2, be fixed with flexible PCT heating film 1, on flexible PCT heating film, be provided with a basic unit 3, in basic unit 3, be provided with water suction writing layer 4, described water suction writing layer 4 is sprayed on basic unit's 3 upper surfaces, wherein, basic unit 3 adopts nonwoven, the basal surface of basic unit 3 carries out water-proofing treatment, reaches water-proof function, and water suction writing layer 4 is the composite film that epoxy resin, polystyrene and silica form, water suction writing layer 4 water absorbing capacities are strong, indiffusion; Described flexible PCT heating film comprises silica gel outer 1c, some groups of PTC ceramic thermistor core sheet 1b and aluminium strip 1a, PTC ceramic thermistor core sheet 1b and aluminium strip 1a are installed in described silica gel outer 1c, aluminium strip 1a is placed in the both sides of PTC ceramic thermistor core sheet 1b, aluminium strip 1a contacts completely with silica gel outer 1c, aluminium strip 1a is connected by conducting resinl with PTC ceramic thermistor core sheet 1b, and PTC ceramic thermistor core sheet 1b and aluminium strip 1a are placed in silica gel outer 1b; In described palette rack 2 one sides, be provided with the supply unit 5 into the power supply of flexible PCT heating film, preferred, according to water-writing plate size, in the present invention, described PTC ceramic thermistor core sheet is rectangle or circle.
PTC ceramic thermal resistance is the semiconductor resistor that a kind of typical case has temperature sensitivity, while surpassing certain temperature, its resistance value is along with the rising of temperature is increasing of step evolution, now, due to its resistivity-temperature characteristics, electric current reduces along with the increase of resistance, when resistance value reaches maximum, PTC chip no longer generates heat, and temperature no longer rises.Aluminium has conduction, heat conduction characteristic rapidly and uniformly, adopts aluminium strip as conduction, heat-conducting medium, has optimized the performance of PTC heating film, owing to self thering is the characteristic of insulation in common silica gel, add existing heat-conducting filler, make its dual property that possesses insulation, heat conduction, safe and reliable.
Below only with embodiment, describe the present invention, but the present invention is not limited to above-mentioned size and outward appearance illustration, more should not form any restriction of the present invention.As long as within any improvement that the present invention is done or modification all belong to the protection domain of the claims in the present invention opinion.
