Description
Technical field
The utility model relates to a kind of calculators.
Background technique
With scientific technological advance, calculator is one of essential calculating tool in people's daily life, but existing
Some calculator functions are relatively simple, have been unable to meet people's lives needs, need to use special meter in specific occasion
Calculate device.
Summary of the invention
In order to solve deficiency in the prior art, the purpose of this utility model is to provide a kind of calculating with heating function
Device.
To achieve the above object, the utility model uses following technical scheme:
A kind of calculator, including shell, the front of shell are equipped with display screen and key, enclosure interior be equipped with battery and by
Battery powered mainboard；The back side of the shell is equipped with heater, which includes velveteen surface layer, heat generating member and heat insulating mattress,
Interlayer is formed between velveteen surface layer and back side of shell, heat insulating mattress is attached on back side of shell, shape between velveteen surface layer and heat insulating mattress
At interlayer, heat generating member is placed in interlayer, and heat generating member is electrically connected by control switch with battery, and the control switch is arranged in shell
On.
Thermal-shutdown circuit is equipped in the shell, thermal-shutdown circuit concatenates shape with heat generating member, control switch and battery
At circuit, the thermal-shutdown circuit includes the temperature-sensitive magnetoelectricity switch and resistance temperature detector of concatenation.
The shell is equipped with the charging interface to charge the battery.
The heat generating member is resistance wire in spiral shape.
The utility model, in intemperance, may be used also while having the function of basic calculation using above technical scheme
Think and used as heating system, realizes multi-purpose content.
Detailed description of the invention
The utility model is described in further details below in conjunction with the drawings and specific embodiments:
Fig. 1 is the front view of the utility model；
Fig. 2 is the rearview of the utility model；
Fig. 3 is the side view of the utility model.
Specific embodiment
As shown in one of Fig. 1-3, a kind of calculator of the utility model, including shell 1, the front of shell 1 are equipped with display
Shield 2 and key 3, the mainboard for being equipped with battery inside shell 1 and being battery powered；The back side of shell 1 is equipped with heater, the heater
Including velveteen surface layer 4, heat generating member 5 and heat insulating mattress 6, velveteen surface layer 4 and shell form interlayer between 1 back side, and heat insulating mattress 6 is attached at
On 1 back side of shell, interlayer is formed between velveteen surface layer 4 and heat insulating mattress 6, heat generating member 5 is placed in interlayer, and heat generating member 5 passes through control
Switch 7 is electrically connected with battery, and the control switch 7 is arranged on shell 1.
It is equipped with thermal-shutdown circuit in the shell 1, thermal-shutdown circuit is concatenated with heat generating member 5, control switch 7 and battery
Forming circuit, the thermal-shutdown circuit include the temperature-sensitive magnetoelectricity switch and resistance temperature detector of concatenation.Overheat protector electricity
(temperature limit is controlled at 45 DEG C), temperature-sensitive when the resistance temperature detector on road detects that 5 temperature of heat generating member is higher than temperature limit
Magnetoelectricity switch disconnection, cutting circuit, heat generating member 5 stop fever, prevent temperature is excessively high from user being caused to scald and protect calculating
Device.
The shell 1 is equipped with the charging interface to charge the battery.
The heat generating member 5 is resistance wire in spiral shape.
Heat generating member 5 is fixed on heat insulating mattress 6 by insulating cement, and insulating cement waterproof itself is anticreep, is fixed using insulating cement
Mode be avoided that heat generating member 5 generate positional shift.
When the temperature of the surroundings is low, heater is opened by control switch 7, heat generating member 5 generates heat, and user holds calculating
When device works, moreover it is possible to have the function of heating, to effectively improve job enthusiasm and working efficiency.In addition, logical overheat protector electricity
Road, it is prominent high or while reaching temperature limit cuts off self-heating circuit in temperature, it plays a protective role.
