Abstract
The utility model relates to a constant-temperature heating module for electric warmers, and belongs to the technical field of electric appliances. The problem that the heater in the prior art is low in heating efficiency is solved. The constant-temperature heating module for electric warmers comprises a PTC heating sheet, a heat conduction layer made of an aluminum shell is arranged on the outer side of the PTC heating sheet, and the PTC heating sheet is electrically connected with a power supply circuit through a USB interface. The constant-temperature heating module for electric warmers has the advantages of quick heating and safe voltage. Charging can be performed conveniently at any time, and especially for office workers, an electric warmer can be directly inserted into a computer through the USB interface for heating. Charging is convenient, the efficiency is high, and the structure is simple.
Description
Technical field
The utility model belongs to technical field of electric appliances, relates to a kind of Diannuanbao, particularly a kind of heated at constant temperature module being applied on Diannuanbao.
Background technology
Diannuanbao product has electric baking pan and the large class of electric hot-water bag two.Wherein, electric baking pan is comprised of heater element (heating wire or other exothermic material) heat-generating disc, thermostat, insulation material (heat-preservation cotton), switch and shell form.Its operation principle is: after switching on power, heater element changes electric energy into heat energy, thermostat action when reaching uniform temperature, and automatic cut-off power, so the heat of electric baking pan inside is outer loose gradually, thereby human body can be obtained transmission heat and warm oneself from electric baking pan.When electric baking pan temperature declines, thermostat resets, the heating of just can again switching on.
Yet the heating element that Diannuanbao adopts is the larger heating elements of profile such as heating wire or fever tablet, and adopt alternating current 220V voltage to charge, its electrothermal calefactive rate is fast, it is larger that but this heating element is only only applicable to profile, holds time on longer Diannuanbao, for some small-sized Diannuanbaos, its radiating rate is fast, corresponding charge frequency is also higher, and frequent charge will certainly cause the reduction of customer satisfaction, and frequently adopts 220V alternating current charging also easily to cause potential safety hazard.
Utility model content
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of heated at constant temperature module being applied on Diannuanbao.
The purpose of this utility model can realize by following technical proposal: a kind of heated at constant temperature module of Diannuanbao, it is characterized in that, comprise PTC heating plate, described PTC heating plate outside is coated with aluminum enclosure, described PTC heating plate is connected with USB interface by wire, between described PTC heating plate and USB interface, is provided with the constant temperature unit that can control connecting and disconnecting of the circuit.
PTC has intensification rapidly, and the heat efficiency is high, energy-conservation, pollution-free, and evenly, the flames of anger, is used safety, long service life, the advantage that power attenuation amount is little in heating.Utilize USB direct current supply, its voltage is safe voltage, and convenient charging at any time, can not bring potential safety hazard, in addition, adopts the aluminum of good heat conductivity to be coated on PTC outside as heat-conducting layer, and its good heat conductivity, facilitates distributing of heat.Constant temperature unit plays the effect of control circuit break-make, and when temperature reaches set point, circuit disconnects, and when temperature is during lower than design temperature, Automatic-heating is to design temperature.
In the heated at constant temperature module of above-mentioned Diannuanbao, described constant temperature unit is thermal relay.Thermal relay is by thermosensitive magnetism material tests and control temperature, realizes the auto switching of circuit.
In the heated at constant temperature module of above-mentioned Diannuanbao, described constant temperature unit comprises temperature inductor and the control switch being arranged on PTC heating plate.By chip pickup temperature signal and send the switch of instruction control circuit.
In the heated at constant temperature module of above-mentioned Diannuanbao, described PTC heating plate thickness is 3～10mm.
In the heated at constant temperature module of above-mentioned Diannuanbao, described PTC heating plate width is 20～40mm.
In the heated at constant temperature module of above-mentioned Diannuanbao, described PTC heating plate length is 30～60mm.
In the heated at constant temperature module of above-mentioned Diannuanbao, described PTC heating plate input voltage is 5～24 V.
Compared with prior art, the heated at constant temperature module of this Diannuanbao has intensification rapidly, and voltage security, by arranging constant temperature unit, break-make that can automatic control circuit, to maintain the temperature of Diannuanbao, in addition, utilize USB interface as power supply, can directly adopt USB interface to be plugged on computer heats, it charges convenient, and efficiency is high, simple in structure.
