Description

The feeding bottle that has displays temperature

This utility model belongs to life appliance feeding bottle improvement technology.

At present, the feeding bottle that people use in life is a kind of glass, makes easily, and simple in structure, cost is low, and is easy to use, is the necessary articles for use that people are had in life.When being to use, its deficiency can't know when the temperature, particularly feeding bottle of carrying liquid breast-feeded to child in the feeding bottle, must make repeated attempts that estimation cold and hot situation is roughly made troubles to life by the people.

For solving above deficiency, the purpose of this utility model provides a kind of feeding bottle that temperature shows that has, to reach the temperature that need not attempt just knowing liquid in the feeding bottle.

This utility model structural design is achieved in that this feeding bottle that has displays temperature is made up of two parts, be liquid container part and electronic temperature measurement part, container part is day common various feeding bottle forms, temperature detector is equipped with in bottom at its container, temperature in the measuring vessel, in the container during no liquid, what record is air themperature, when in the container liquid being arranged, what record is temperature of liquid, and temperature measurement fraction is an electronic installation, be installed in the bottom of feeding bottle, the digital screen of displays temperature value is housed in the bottom of container, is provided with switching device in the bottom of feeding bottle, temperature measurement fraction is by shown in Figure 2.(its circuit structure is illustrated in conjunction with the embodiments)

Fig. 1 is the feeding bottle shape assumption diagram that has displays temperature;

Fig. 2 is the feeding bottle logic diagram that has displays temperature;

Fig. 3 has the feeding bottle electrical schematic diagram that temperature shows.

It is that the front is temperature sensor that circuit connects, its output connects V-F circuit (voltage-frequency converting circuit), the output of V-F circuit connects pulse shaper, pulse shaper is output as counting circuit, counting circuit output passing through decoding circuit, connect with charactron by drive circuit simultaneously, the input of counting circuit has the pulse per second (PPS) oscillating circuit, by the time main pulse and blanking pulse connect to decoding circuit, for providing the cycle, number shows, its work process is that temperature detector is transformed into voltage signal to heat energy, give V-F circuit (voltage-frequency converting circuit), the frequency signal of V-F circuit output is after the shaping circuit shaping, the pulse signal of standard is delivered to counting circuit count processing, the binary-coded decimal of output is delivered to decoding circuit, converts ten's digit to, and on digital screen, show, finish the process from the thermometric to the displays temperature.The pulse per second (PPS) oscillating circuit produces clock signal second of standard, for counting circuit provides counting to basic signal strobe and blanking signal, dynamic driver circuit converts the clock signal of counting circuit output the driving signal of dynamic demonstration to, for dynamic display digit screen provides sheet to select voltage.

Its thermometric physical circuit as shown in Figure 3, IC ₁Be the thermometric integrated circuit, be installed in container bottom, the temperature in the measuring vessel, and temperature transition become voltage signal, the voltage signal of being changed is proportional with the temperature that records, IC ₁Be LM35Z.

IC ₂Be V-F circuit (voltage-freq converting circuit), IC ₁Voltage signal to IC ₂After, IC ₂Voltage signal is converted to and IC ₁The frequency signal that output voltage is directly proportional is adjusted W ₅Can change IC ₂The signal frequency of output, IC ₂Be LM331.

IC ₃Be Schmidt circuit, be used for producing the required clock signal of circuit, offer IC ₄Time base signal strobe and blanking signal, W ₂, C ₂Form clock signal oscillation circuit, produce the pulse per second (PPS) oscillator signal of standard, adjust W ₂Can change frequency of oscillation, IC ₃Also undertake signal shaping work.To from IC ₂Signal carry out shaping and handle the rectangular wave pulse of outputting standard, IC ₃Be CD40106.

IC ₄Be counting circuit, IC ₄To IC ₃The pulse duration frequency signal consistent with temperature of output is that unit counts with the second, produces the binary-coded decimal signal of three bit digital, simultaneously IC ₄Also produce and export dynamic digital and shield needed time sequential pulse signal, BG ₁, BG ₂Be dynamic driving audion, IC ₄Be CD4553, audion is 9012.

IC ₅Be decoding output circuit, IC ₄The binary-coded decimal of sending here is through IC ₅Be translated into decimal system number, and output gives digital screen, show temperature-measuring results, digital screen is made up of LED luminous digital piece, can show two decimal numbers, and promptly 00-99, IC ₅Be CD4511.

The advantage of this device: simple in structure, modern design, feeding bottle is with temperature indicating device, Easy to use.
