The LED displayer is arranged on the outer side of the bag body and composed of various-colored LEDs, the LED displayer is connected with the micro controller to set different temperature zones, and different-colored LEDs can be displayed according to internal temperature of the bag body. The power supply module can provide power, is composed of button cells, is arranged at the bottom of the bag body and can be opened through a knob to be replaced. The temperature measurement circuit is connected with the micro controller, is composed of thermistors, is arranged on the inner surface of the bag body and can sense internal temperature of the bag body. The LED temperature display thermal insulation bag has the advantages of being capable of visually displaying temperature in the bag in real time, convenient and practical and low in cost.
Description
Technical field
The utility model relates to the insulation bag that a kind of LED temperature shows.
Background technology
Adopt the insulation contracted affreightment to send the article that need insulation, and the food of standby insulation packing hot water or heat being incubated when cold in the sky, and preserving cold drink or other article that need refrigerate at the time standby insulation bag of sky heat, is frequent thing.But there is the place of several inconveniences with traditional insulation bag, can not intuitively shows such as insulation bag internal temperature, can not understand the internal temperature situation from the outside; Can only open clad and will understand internal temperature, inconvenient operation not only, and reduce heat insulation effect greatly.
Summary of the invention
The utility model purpose is in order to overcome above-mentioned weak point, the insulation bag of LED temperature demonstration to be provided, can intuitively showing temperature in the bag by color, and is convenient and practical, practical.
The technical scheme that its technical matters that solves the utility model adopts is:
The insulation bag that the LED temperature shows comprises inclusion, and clad also comprises, is installed in the light-emitting diode display of described inclusion upper end, is installed in the power module of described inclusion bottom, is installed in the micro controller of described inclusion bottom, is installed in the temperature measurement circuit of described inclusion inboard.
Described light-emitting diode display is arranged on the lateral surface of described inclusion, is made up of the LED of multiple color.
Described light-emitting diode display is connected with described micro controller, and different temperature ranges is set, and according to the temperature range that water temperature is in, shows the LED of different colours.
Described power module can provide power supply, is made up of button cell, is arranged on the bottom of described inclusion, can open by knob, changes.
Described temperature measurement circuit is connected with described micro controller, is made up of thermally dependent resistor, is arranged on the inside face of described inclusion, can respond to described inclusion temperature inside.
The beneficial effects of the utility model mainly show: show insulation bag temperature inside in real time by different colors, and very directly perceived, easy to use.
Description of drawings
Fig. 1 is the profile scheme drawing of insulation bag;
Fig. 2 is the control principle figure of insulation bag;
Fig. 3 is the temperature measurement circuit schematic diagram of insulation bag.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1-3, the insulation bag that the LED temperature shows comprises inclusion 1, clad 2 is installed in the light-emitting diode display 3 of described inclusion 1 upper end, is installed in the power module 5 of described inclusion 1 bottom, be installed in the micro controller 4 of described inclusion 1 bottom, be installed in the temperature measurement circuit 6 of described inclusion 1 inboard.
Described light-emitting diode display 3 is arranged on the top of described inclusion 1, is made up of the LED of multiple color, is divided into cool tone and warm tones, and cool tone is such as blue and green, and warm tones is such as yellow, red.Light-emitting diode display 3 is connected with described micro controller 4, and micro controller 4 arranges different temperature ranges, according to the internal temperature of described inclusion 1, shows the LED of different colours, and color is more bright-coloured, and temperature is more high.Represent temperature drift such as yellow, but be unlikely to cause scald, and red expression temperature is very high, cause scald easily, and color more cool colour represent that temperature is more low, represent that such as green temperature is lower, can cause the human discomfort of drinking, and blue expression temperature is very low, near freezing point.
Described power module 5 is used to this device power supply.Adopt the little button cell of volume to form, be arranged on the bottom of described inclusion 1, can open by knob, change.
Described temperature measurement circuit 6 is connected with described micro controller 3, for detection of the temperature in the described inclusion 1.R2 forms by thermally dependent resistor, is arranged on the inside face of described inclusion 1.Adopt circuit structure as shown in Figure 3, resistance R 1 one ends are connected with power supply VCC, and the other end connects AD port and the thermally dependent resistor R2 of micro controller 4, and the described thermally dependent resistor R2 other end connects ground GND, two ends parallel capacitance C1 simultaneously.The resistance of thermally dependent resistor R2 changes along with variation of temperature, and the input voltage of the AD port of micro controller 3 also changes thereupon, therefore just can obtain concrete Temperature numerical by the numerical value of measuring this voltage.
Concrete working process is as follows: at first, micro controller 4 is changed the input voltage that reads temperature measurement circuit 6 by analog digital, and this magnitude of voltage is followed temperature traverse and changed; Then, micro controller 4 calculates temperature according to the property list of thermally dependent resistor R2; At last, micro controller 4 control light-emitting diode displays 3 show different colors.
In sum, the utility model has overcome the problems referred to above that existing insulation bag exists, can be on the inclusion surface temperature in the real-time demonstration bag intuitively, convenient and practical, safe.
