Description

Pacifier Thermometer

[technical field]

The present invention relates to a thermometer, in particular to a pacifier thermometer.

[Background technique]

Before the invention of electronic thermometers, mercury thermometers were widely used to measure the body temperature of the human body. People made mercury thermometers by using the principle that mercury naturally expands when it is heated and shrinks when it is cold. The mercury naturally expands when the probe (i.e. the mercury temperature sensing cylinder) is heated, and part of the expanded mercury is sent into the capillary in the glass rod. At this time, the user can read the measurement result through the scale printed on the outside . But in recent years, due to the high pollution of mercury, electronic thermometers that use electronic technology to measure temperature have emerged as the times require, and have gradually replaced the old highly polluted mercury thermometers.

The measurement principle of the electronic thermometer is to use the built-in timing circuit of the integrated circuit to calculate the time required for the RC oscillation circuit formed by the externally connected reference resistance and capacitance to oscillate to a specific number of times as the reference time, and then switch to the temperature-sensitive resistor ( Temperature sensing element) performs RC oscillation with the same capacitor in the above oscillation circuit, and obtains the number of oscillations within the reference time, and converts it into a data signal through the internal operation of the microprocessor and sends it to the display, which is the measured temperature value .

Since the calculation of the temperature value is based on the above principle, when the RC oscillating circuit composed of the reference resistor and capacitor, the RC oscillating circuit composed of the temperature-sensitive resistor and the same capacitor as above is under a certain condition through the built-in oscillator in the integrated circuit When the oscillation frequency after the sequential oscillation is equal, it can reach the preset temperature value in the integrated circuit (generally set to 37°C or 98.6°F), and based on the temperature value when the oscillation frequency is equal, calculate Other temperature values represented by the difference of the above two groups of oscillation frequencies. Since the above-mentioned two groups of oscillating resistors share the same capacitor, if the temperature difference value after calculation is to be kept within a certain range, then at a specific temperature (the setting of the general ambient temperature is: the reference resistor is 25°C, The temperature-sensitive resistor is 37°C) The resistance difference between the reference resistor and the temperature-sensitive resistor should also be kept within the corresponding range. The measurement circuit design of the conventional electronic thermometer is to fix the reference resistor and the temperature-sensitive resistor on the measurement circuit board. Therefore, the matching results of the reference resistor and the temperature-sensitive resistor are not interchangeable.

Electronic thermometers are not fragile, non-polluting, have high measurement accuracy and short measurement time, and have gradually replaced mercury thermometers with high pollution. In recent years, due to the continuous evolution and improvement of technology and the general consumption With the improvement of the level, the electronic thermometer has increasingly gained the trust of users, and has gradually become an indispensable health care must-have in the public medical field such as hospitals or ordinary families.

Usually, if you use an electronic thermometer to measure the baby's body temperature, because the baby is young, it often moves around unsteadily, and it is difficult to measure the correct body temperature; while the baby is in a stable emotional state when sucking a pacifier, At this time, it is convenient to measure the temperature, so a pacifier thermometer with a pacifier combined with a thermometer is produced.

The commonly used pacifier thermometer usually has its measuring body (including temperature sensing element, circuit board) and the pacifier combined together, and cannot be disassembled and assembled separately, so it has many defects:

1. Because the baby's resistance is weak, in order to avoid infection by various viruses and bacteria, the user often cleans and washes the pacifier. Therefore, if the baby is cleaned with water, the measuring body will be damp and prone to failure.

2. Since the measuring body is combined with the nipple, when the nipple is bitten off, it must be thrown away entirely, which is really a waste.

3. Since the temperature sensing element is located in the main body of the pacifier, it is often bitten and damaged. Since the measuring body and the pacifier are combined, the whole must be thrown away, which is really a waste.

4. Measuring body temperature with a pacifier thermometer Due to the emphasis on hygiene and safety, the measuring body and the pacifier are combined together. Therefore, usually a pacifier thermometer is used exclusively by one person. It is not economical to use it in a medical institution.

In addition, a traditional electronic thermometer is used to measure body temperature. When the measured temperature reaches a stable level, the light generator will light up or the buzzer will sound as a signal to measure the stability of the temperature, and the display used to display the measured temperature , it is usually not equipped with a backlight device, which cannot assist the user to easily identify the measurement results, or the display is equipped with a backlight device, and the time when the backlight device is on is short, often when the user wants to pick up the thermometer to view the temperature number , the light is off, making it difficult to identify the measurement results.

Although the conventional electronic thermometer is equipped with a buzzer to send out an audible signal after the measured temperature is stable, the buzzer has a sound box structure, so it takes up a lot of volume of the thermometer.
