Abstract
The utility model relates to a temperature-sensing warning cup mat powered by temperature differences, which consists of a temperature-sensing warning circuit and a protective cover. The temperature-sensing warning circuit consists of a temperature difference power generation plate, a temperature sensor, a micro-control unit and an LED luminous circuit which are serially connected. The temperature-sensing warning circuit of the cup mat is powered by the temperature difference power generation plate, the temperature sensor acquires temperature, and the micro-control unit controls LEDs to emit light in different colors according to differences of temperatures. The temperature-sensing warning cup mat does not need other power sources, is energy-saving and environment-friendly, can emit the light in different colors according to differences of temperatures of drinking water or drinks, has a warning function for people, and simultaneously brings visual enjoyment for people.
Description
Technical field
The utility model relates to a kind of daily necessities, the temperature sense that relates in particular to the power supply of a kind of temperature difference plate mat of warning.
Background technology
In daily life, for the cup that prevents to contain hot water damages desktop, the time cup of being everlasting transfer a plate mat.But traditional plate mat only plays heat insulation function, function singleness.Plate mat generally is placed on the desktop, and people can't be known the height of water tumbler temperature.People still can pick up cup inadvertently, and when water in the cup or beverage temperature were higher, regular meeting caused scald because of carelessness.
Summary of the invention
To the defective that exists in the above-mentioned prior art, the purpose of the utility model be to provide a kind of have simultaneously warn, the temperature sense of the temperature difference power supply of heat insulation and decoration functions is warned plate mat.
The solution that the utility model provides is following: the temperature sense of a kind of temperature difference power supply plate mat of warning, form by warn circuit and sheath of temperature sense.The temperature sense circuit of warning is made up of thermo-electric generation sheet, temperature sensor, micro-control unit and the series connection of LED illuminating circuit.Plate mat is by the temperature sensor collecting temperature, and is different according to temperature, and the temperature light that circuit micro-control unit controls LED sends out different colours of warning is warned.
The described temperature sense circuit of warning provides power supply by the thermo-electric generation sheet.
The described temperature sense circuit of warning is sent out different colours light by micro-control unit according to the different control of temperature LED.
The beneficial effect of the utility model is: the temperature sense of the described temperature difference power supply plate mat of warning need not use other power supplys; Energy-conserving and environment-protective; And plate mat is according to the difference of drinking water or beverage temperature; Send the light of different colours, can work the effect of warning, give people simultaneously with visual enjoyment to people.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation.
Fig. 1 is the structural representation of the utility model.Among the figure, 1 is LED1, and 2 is LED2, and 3 is LED3, and 4 is LED4, and 5 is LED5, and 6 is LED6, and 7 is LED7, and 8 is LED8, and 9 is temperature sensor, and 10 is the thermo-electric generation sheet, and 11 are the temperature circuit board of warning, and 12 is the resin-encapsulated sheath.
Fig. 2 is the thermo-electric generation sheet fundamental diagram of the utility model.Among the figure, 1 is thermal source, and 2 is the hot junction, and 3 is cold junction, and 4 is n type material, and 5 is P-type material.
Fig. 3 is the circuit theory diagrams of the utility model.Among the figure, 1 is LED1, and 2 is LED2, and 3 is LED3, and 4 is LED4, and 5 is LED5, and 6 is LED6, and 7 is LED7, and 8 is LED8.
The specific embodiment
Among Fig. 1, plate mat is made up of with resin-encapsulated sheath 12 warn circuit 11 of temperature sense.The temperature sense circuit 11 of warning provides power supply by thermo-electric generation sheet 10, temperature sensor 9 collecting temperatures, and the micro-control unit controls led circuit is luminous.LED1 and LED2 glow, LED3 and LED4 jaundice light, and LED5 and LED6 blue light-emitting, LED7 and LED8 glow.
Among Fig. 2, by PN junction of the continuous formation of P type 5 and 4 two kinds of dissimilar thermoelectric materials of N type (the P type is a rich hole material, and the N type is the electron rich material) end, a continuous end is hot junction 2, and the relative other end is a cold junction 3.Under the effect of thermal source 1, end 2 forms high temperature, and end 3 forms low temperature; Because the thermal excitation effect, P (N) type material temperature end hole (electronics) concentration is higher than low-temperature end, receives the driving of concentration gradient; Hole and electronics spread to low-temperature end; Form electromotive force, thereby thermoelectric material directly changes into electric energy with the heat energy of temperature end input, for the temperature sense circuit of warning provides power supply.
Among Fig. 3, micro-control unit controls LED illuminating circuit driving LED is sent the light of different colours.Temperature sensor detects current water tumbler temperature, and temperature accuracy is 1 ℃.When temperature during greater than 47 ℃, LED1 and LED2 glow, and the expression water temperature is very high, and reminds people is careful; When temperature during at 36-47 ℃, LED3 and LED4 jaundice light, the expression water temperature is higher, and reminds people will be noted; When temperature during at 26-36 ℃, LED5 and LED6 blue light-emitting, the expression water temperature is moderate; When temperature during less than 26 ℃, LED7 and LED8 green light, the expression water temperature is cool.Along with variation of temperature, LED illuminating circuit driving LED is sent the light of different colours, and the existing effect of warning is attractive in appearance again, pleasing.
