Abstract
The utility model relates to the technical field of school supplies, particularly to a writing board. The writing board comprises a base, wherein a cavity is formed in the base, a glass cover plate is inlaid in the cavity in a matching manner, a heating device is arranged at the bottom end of the glass cover plate and comprises a power line, one end of the power line coils the bottom end of the glass cover plate, one tip of the coiled power line is connected with heaters, the heaters and the coiled power line are covered with a heat dissipation material layer, and the other end of the power line is connected with a regulating switch. According to the writing board, the heating device is arranged at the bottom of the base and adopts heaters instead of heating coils, and the heaters are coated with the heat dissipation material layer; in addition, the regulating switch is arranged at one end of the power line, and the temperature can be regulated according to personal needs, so that damage and burn to skins due to overload of the heating coils can be prevented, and the service life can be prolonged; and the heaters are matched with the glass cover plate for usage, heat is evenly distributed by means of the heat dissipation material layer, and warm keeping for hands and feet is facilitated by the aid of the glass cover plate.
Description
Technical field
The utility model relates to study article technical field, particularly a kind of board.
Background technology
Due to winter temperature very low, desk is also very ice-cold, student is in when study, trick often can be by numb with cold, thereby affect results of learning.
For above problem, in prior art, there is a kind of heating writing board, it comprises board, and board below is provided with heating wire, and heating wire is connected with power line.Although the board of the type has warming effect,, its heating wire is after switching on power, because size of current is fixing unadjustable, therefore temperature can continue to rise, after long-time use, can burn out heating wire, also burned skin likely, and also higher to the material requirements of board.In addition, the board of the type can only be used for the warming of hand, but student is in the process of study, usually except hand is cold, due to for a long time in sitting state, therefore it is cold that pin also can be felt, and board of the prior art is owing to being provided with the problem etc. of decorating line or anti-slip veins or material, inconvenient foot portion warm keeping.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides one to prevent that heating wire overload from burning out and burned skin, increases the service life, and temperature control is convenient, is convenient to the warming board of hand and pin.
For achieving the above object, the utility model is by the following technical solutions: a kind of board, comprise base, in base, offer cavity, in described cavity, coordinate edge to be provided with glass cover-plate, glass cover-plate bottom is provided with electro-heat equipment, electro-heat equipment comprises power line, and coil in glass cover-plate bottom one end of power line, and the termination of the power line of coiling is connected with heating element, the power line of heating element and coiling is coated with the radiative material bed of material outward, and the other end of power line is connected with by-pass cock.
Wherein, between the described radiative material bed of material and glass cover-plate, be provided with heat-insulation layer.
Wherein, described cavity inner edge is provided with the mounting table for placing glass cover plate, and described glass cover-plate is bonding or be screwed onto mounting table upper end.
Wherein, in described base, a side offers the through wires hole for wearing power line, and base bottom is provided with fixing feet, and base middle part offers installing hole.
The utility model beneficial effect is: the utility model comprises base, in base, offer cavity, in described cavity, coordinate edge to be provided with glass cover-plate, glass cover-plate bottom is provided with electro-heat equipment, electro-heat equipment comprises power line, and coil in glass cover-plate bottom one end of power line, and the termination of the power line of coiling is connected with heating element, the power line of heating element and coiling is coated with the radiative material bed of material outward, and the other end of power line is connected with by-pass cock; The utility model is by being provided with electro-heat equipment in base bottom, and this electro-heat equipment adopts, be heating element but not heating wire, by the radiative material bed of material, heating element is coated, in addition, power line one end is provided with by-pass cock, can regulate temperature height according to individual demand, can prevent that like this heating wire overload from burning out and burned skin, increase the service life, and heating element and glass cover-plate is used in conjunction with, by the radiative material bed of material, heat is uniform, and glass cover-plate is convenient to hand and pin is warming.
