Description
Technical field
The utility model relates to the water drinking utensil field on dining table, specifically a kind of can the cup of perception water temperature.
Background technology
The cup of water temperature can be detected, can prevent to a great extent water temperature over-high or too low cause uncomfortable, existing a lot of relevant design, such as patent disclosed in CN103859932A.
Most prior art biases toward functional realiey, and practicality is not strong.For accurately reading thermometer or understanding the adult of digital display meter, the cup of display water temperature itself has little significance.For lacking the Children and teenager of judgement, even if demonstrate water temperature, but this part crowd, the reading of thermometer of often failing to understand, even and if in the face of digital display meter, do not remember suitable water temperature range yet.
In addition, the placement of temperature sensor should be scientific and reasonable, otherwise the temperature detected, compared with actual temperature, has very large deviation, does not have the effect of correct indicated temperature.
Summary of the invention
The utility model is exactly the problem that can not show or can not accurately and intuitively show the water temperature in cup for existing cup, propose a kind of can the cup of perception water temperature.
The utility model is achieved in the following ways.
Can the cup of perception water temperature, comprise cup and base, base is provided with the inner fovea part measure-alike with bottom of cup, is provided with sheet metal at the center of described inner fovea part, and sheet metal lower surface posts thin-film thermistor R1 and diaphragm pressure resistance R2; Described thermistor R1, piezoresistive R2 are connected with single-chip microprocessor MCU by the amplifier OP be arranged in base, and single-chip microprocessor MCU is also connected with the indicator lamp be arranged on base, and power supply BAT is that each parts are powered; Described thermistor R1, piezoresistive R2 and amplifier OP, single-chip microprocessor MCU, indicator lamp, power supply BAT form closed circuit jointly.
The utility model has following beneficial effect.
The utility model structure is simple, easy to use, be widely used, and water temperature display is more accurate, more intuitively.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further elaborated.
Can the cup of perception water temperature, comprise cup 1 and base 2, base 2 is provided with the inner fovea part 4 identical with cup 1 bottom size, is provided with sheet metal 5 at the center of described inner fovea part 4, and sheet metal 5 lower surface posts thin-film thermistor R1 and diaphragm pressure resistance R2; Described thermistor R1, piezoresistive R2 are connected with single-chip microprocessor MCU by the amplifier OP be arranged in base 2, and single-chip microprocessor MCU is also connected with the indicator lamp 3 be arranged on base 2, and power supply BAT is that each parts are powered; Described thermistor R1, piezoresistive R2 and amplifier OP, single-chip microprocessor MCU, indicator lamp 3, power supply BAT form closed circuit jointly.
The circuit of described base 2 inside is: be made up of devices such as button cell BAT, operational amplifier OP, microcontroller, LED lamp bead and multiple resistance; Thin-film thermistor R1 connects with a precision resister R3, and tie point is received the input channel 1 of operational amplifier OP, another termination battery of thin-film thermistor R1 BAT positive pole, another termination battery of precision resister R3 BAT negative pole.Diaphragm pressure resistance R2 connects with another precision resister R4, and tie point is received the input channel 2 of operational amplifier OP, another termination battery of diaphragm pressure resistance R2 BAT positive pole, another termination battery of precision resister R4 BAT negative pole.Two output channels of operational amplifier OP are received on two input pins of microcontroller respectively.3 output pins of microcontroller are connected with the anode of red colored lamp pearl L1, green light pearl L2, amber light pearl L3 respectively, and the negative electrode of three lamp pearls is received together, and receives battery BAT negative pole by current-limiting resistance R.
The model of above-mentioned amplifier OP is LM358; The model of microcontroller is MSP430F1, Texas Instrument; Button cell is 3.6V; Thin-film thermistor R1 model is ttf-103; Diaphragm pressure resistance R2 model is fsr-402; Precision resister R3=R4=10k Ω; Current-limiting resistance R=510 Ω; LED is general paster LED lamp, 0603 encapsulation.
Described cup 1 comprises inner bag 6, insulating surface 8 and is arranged on heating column 7 identical with sheet metal 5 size bottom cup 1.
When cup is placed on base, heating column 7 bottom cup 1 is fitted with the upper surface of sheet metal 5, in cup, the heat of water and gravity are delivered to sheet metal 5 by heating column 7, and by the thin-film thermistor R1 of sheet metal 5 lower surface and the perception of diaphragm pressure resistance R2 institute.When after circuit ON, can because the difference of temperature and pressure, the resistance value of R1, R2 is different, thus voltage on R3, R4 is also different, voltage signal is amplified into single-chip microprocessor MCU by operational amplifier OP, the analog-digital converter ADC of single-chip microprocessor MCU inside, by after voltage signal quantification, contrasts with a reference value, can judge Current Temperatures and pressure.Pressure value is used for judging currently whether have cup to place, and when not having cup to place more than 10 seconds, circuit can close indicator lamp automatically.When there being cup to place, if temperature is higher than 55 degree, it is luminous that single-chip microprocessor MCU controls red colored lamp pearl L1; When temperature is lower than 20 degree, it is luminous that single-chip microprocessor MCU controls amber light pearl L3, and when temperature is between 20 degree and 55 degree, it is luminous that single-chip microprocessor MCU controls green light pearl L2.Temperature range can also be carried out the division of more refinement by the utility model, as every 10 DEG C of changes just can make lamp pearl carry out the change of color.
The utility model is applicable to common cup, and when common cup is placed on base 2, thin-film thermistor R1 and diaphragm pressure resistance R2 equally can by signal transmission to single-chip microprocessor MCU.In addition, cup 1 described in the utility model has thermoinsulated external wall 8, and the heat of prevention is to the propagation in other directions, and heat is concentrated by heating column and metal dish by thermistor perception, and the temperature recorded is closer to the actual temperature of water; Meanwhile, the utility model has diaphragm pressure resistance R1, and when cup is not placed on base 2, circuit will close indicator lamp 3, has saved the electricity of battery.So the utility model has good application prospect.
