CN201929568U - Cup capable of measuring temperature - Google Patents

Abstract

The utility model provides a cup capable of measuring temperature, which comprises a cup body, a cup handle, a first switch, a second switch, a third switch, a thermister and an LED. The cup has the advantages that by utilizing the characteristic that resistance value of the thermister increases along with the increase of temperature, when the temperature drops to a preset temperature, an indicator light on the cup is lit to remind people that the temperature of water drops, thereby reducing the occurrence of accidents.

Description

But a kind of cup for measuring temperature

Technical field

The utility model relates to a kind of cup, but especially relates to a kind of cup of thermometric.

Background technology

Have many people to like drinking hot water in the reality, especially to winter, people are often glad to hold one glass of hot water in hands, but often occur because of water too blanching hinder the situation of mouth.

Summary of the invention

But the purpose of this utility model provides a kind of cup for measuring temperature, the characteristics that the resistance of utilizing thermistor raises with the rising of temperature, and when temperature descends when reaching preset temperature, the indicator lamp on the cup can be bright, and reminds people can have been drunk now.

The technical solution of the utility model is: but a kind of cup for measuring temperature, comprise cup, cup handle, first switch, second switch, the 3rd switch, thermistor and light emitting diode, it is characterized by first switch, second switch, the 3rd switch and be arranged in cup successively from top to bottom last, thermistor is installed in the cup middle and lower part apart from cup inwall 0.5 centimeters, and light emitting diode is fixed on the cup outer wall;

Wherein second switch, thermistor, first resistance and semifixed resistor form temperature measurement circuit with the lead series connection, the 3rd switch is with after second resistance is connected, in parallel with temperature measurement circuit, this parallel circuit inserts positive source and light emitting diode positive pole, and the light emitting diode negative pole connects into power cathode with first switch series; Wherein the semifixed resistor and second resistance all are fixed on the cup outer wall.

Advantage that the utlity model has and the good effect characteristics that to be the resistance of utilizing thermistor raise with the rising of temperature, when temperature descends when reaching preset temperature, the indicator lamp on the cup can be bright, and the reminds people water temperature descends, reduces unexpected the appearance.

Description of drawings

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the cup circuit connection diagram.

The specific embodiment

As shown in Figure 1 and Figure 2, but a kind of cup for measuring temperature of the utility model, comprise that cup 1, cup are 2, first switch 3, second switch 4, the 3rd switch 5, thermistor 6 and light emitting diode 7, it is characterized by first switch 3, second switch 4, the 3rd switch 5 and be arranged in cup successively from top to bottom on 2, thermistor 6 is installed in cup 1 middle and lower part apart from cup 1 inwall 0.5 centimeters, and light emitting diode 7 is fixed on cup 1 outer wall;

Wherein second switch 4, thermistor 6, first resistance 8 and semifixed resistor 9 form temperature measurement circuit with the lead series connection, the 3rd switch 5 is with after second resistance 10 is connected, in parallel with temperature measurement circuit, this parallel circuit inserts power supply 11 anodal and light emitting diode 7 positive poles, and light emitting diode 7 negative poles are connected with first switch 3 and inserted power supply 11 negative poles; Wherein the semifixed resistor 9 and second resistance 10 all are fixed on cup 1 outer wall.

The course of work of this example: pour hot water in cup, open first switch 3, this moment, way circuit was connected, second switch 4 is the thermometric switch, open second switch 4, enter the thermometric program, when temperature descends, the resistance of thermistor 6 reduces, thereby the dividing potential drop of light emitting diode 7 is increased, and when voltage reached rated voltage, light emitting diode 7 was lighted, remind the user that water temperature has dropped to preset temperature, can set and change preset temperature by regulating semifixed resistor 9; The 3rd switch 5 is a sense switch, and when closed the 3rd switch 5 only, the Light-Emitting Diode 7 bright Light-Emitting Diodes 7 of then representing are intact.

More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
