Abstract
The invention relates to an electric heating table mat with a self-limited temperature. Electric-heating table mats on the market at present generally do not have a temperature self-limiting function, and the table mats form surface superheat in case of continuously heating to cause local burn-out or short-circuit, so that unsafe factors are brought to cause harm on a user. The electric heating table mat with the self-limited temperature comprises an electric heating table mat main body (1), wherein an electric heating film (10) inside the electric heating table mat main body is connected with a power supply connecting card (3); the power supply connecting card is connected with a power supply switch (5); the power supply switch is provided with a temperature display device (6), a temperature regulating button (7), a switch button (8), an on-off electric indicating lamp (2); and the power supply switch is connected with a power adapter (9). The invention is used for the electric-heating table mat with the self-limited temperature.
Description
Technical field:
The present invention relates to a kind of mat applying, be specifically related to a kind of self limiting temperature electrothermal table mat and preparation method thereof.
Background technology:
The rise of electrothermal table mat is primarily due to the reduction of winter temperature and the raising that ambient temperature comfort level is required by people.Especially the work and study of working people and student, the warming of hands is particularly important, because little motion before being sitting in desk or study table for a long time, so the blood circulation of whole body is inadequate, especially easy occur that trick is ice-cold stiff, finger becomes dumb, and even somebody chilblain can occurring on hand, thus have impact on the efficiency of work and learning initiative.We accelerate blood circulation mode by the simple of tradition " stranding is rubbed hands, and stamps one's foot ", and effect is extremely limited, so my company, according to market demand independent research electrothermal table mat, brings warm for people；
At present electrothermal table mat on the market is all generally do not possess self limiting temperature function, and it is overheated and cause partial burnt-out or short circuit that mat applying will form surface when continuous heating heats up, thus bringing unsafe factor, causes the injury to user.
Summary of the invention:
It is an object of the present invention to provide a kind of self limiting temperature electrothermal table mat and preparation method thereof.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of self limiting temperature electrothermal table mat, its composition includes: electrothermal table mat main body, the Electric radiant Heating Film of described electrothermal table mat body interior connects power supply Connection Card, described power supply Connection Card connects on and off switch, described on and off switch has temperature indicating device, temperature adjustment buttons, shift knob, power on/off display lamp, and described on and off switch connects power supply adaptor.
Described self limiting temperature electrothermal table mat, described electrothermal table mat main body includes extraneous adornment film, radiation prevention film, the first dielectric film, described Electric radiant Heating Film, the second dielectric film.
Described self limiting temperature electrothermal table mat, described Electric radiant Heating Film includes PET(Polyethyleneterephthalate) metallized film, PTC(PositiveTemperatureCoefficient) conductive oil ink film, PET glued membrane.
Described self limiting temperature electrothermal table mat, described electrothermal table mat size of main body length is 600mm, and wide is 360mm.
The manufacture method of the self limiting temperature electrothermal table mat that one of a kind of claim 1-5 is described, this comprises the steps:
The Electric radiant Heating Film of described self limiting temperature electrothermal table mat is internal adopts PET metallized film to be etched into conducting circuit pattern, at described PET metallized film printed thereon PTC electrically conductive ink, on described PTC electrically conductive ink, one layer of PET glued membrane is adhered to as protection again through combination process, and at terminals, power supply Connection Card is installed, it is that the first dielectric film carries out insulation protection on described PET glued membrane, it is radiation prevention film above the first described dielectric film, second dielectric film is presented herein below at described PET metallized film, outermost layer at described self limiting temperature electrothermal table mat is that leather and natural rubber are as extraneous adornment film, on and off switch is installed at product power supply Connection Card place, described on and off switch connects power supply adaptor, during electrothermal table mat energising, power can decline along with the rising of surface temperature, realize self limiting temperature.
The invention has the beneficial effects as follows:
The present invention has the function that is rapidly heated, and is brought rapidly up after opening switch, within 3 minutes, quickly exceeds normal body temperature's (37 DEG C)；Have from limitting temperature incubation function, after having heated up, remain steady temperature scope about 40 DEG C；The present invention is simple to operate, connects attaching plug, and toggle switch can use；Low-voltage safety, running voltage is 24V, 24V is human safety voltage's scope, uses safety relieved；Easy to carry, product has certain flexibility, it is possible to rolls and is convenient for carrying；Save space: product integral thickness, less than 3mm, frivolous is not take up desk-top space.
The running voltage of the present invention is 24V, rated current: 5A；Rated maximum power: 120W.The present invention is prevented from continuous heating surface temperature hot-spot and causes diaphragm to damage, thus protecting product self and unnecessary fire safety evaluating hidden danger.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of the present invention.
Accompanying drawing 2 is the structural representation of the mat applying main body of the accompanying drawing 1 of the present invention.
