[Detailed description of the invention]

[Technical field to which the invention belongs]

 The present invention relates to a tunable heating thermometer, and more particularly to a thermometer having a tunable heater. When measuring the body temperature, the inside of the housing is heated to a certain temperature by the heater, and the absorption of energy by the measuring end of the housing is avoided, so that the speed of measuring the body temperature is remarkably improved. You can do it.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventional electronic thermometers include a structure without a traditional preheating device and a structure with a preheating device. In the thermometer without the preheating device (see Fig. 4), the measuring end of the thermometer was made of metal material. The human body temperature can reach about 35 ° C in just a few seconds, but the energy absorbed from the measurement end is further absorbed by the housing and dissipated, reducing the speed at which the body temperature is measured. . When using a traditional electronic thermometer, it takes two to three minutes to measure the temperature accurately.

On the other hand, as shown in FIG. 1, a conventional thermometer equipped with a preheating device is provided with a tip 2 ′ connected to a double conductor 3 ′ at a measurement end 11 ′ in front of a housing 1 ′. Since one heater 4 'is provided except that the tip 2' is provided in the measuring end 11 ', the heater 4' is used to preheat the housing 1 'before the body temperature is measured. Thus, the body temperature can be measured quickly.

However, the thermometer provided with the above-described preheating device has the following disadvantages. <B> The chip 2 'and the heater 4' are provided at the same time in the internal space of the measuring end 11 '. However, since the internal space of the measuring end 11' is narrow, the technical skill required to mount the heater 4 'is provided. And its manufacture is relatively difficult. <B> In addition, since only the heater 4 'having a very small volume is mounted in the measuring end 11', the heating speed tends to be slow. <C> In addition, since the chip 2 'and the heater 4' are arranged close to each other, there is a sufficient risk of erroneous determination or malfunction. That is, when heating is performed by the heater 4 ′, the energy generated by the heater 4 ′ cannot be heated evenly to the measuring end 11 ′. There is a problem that conduction is conducted up to the chip 2 ′, resulting in an erroneous determination. <D> After preheating with a thermometer, the time taken for measurement can be significantly reduced, but the preheating time is relatively long (since the heater 4 'with a small volume as described above was used). And the total time required to complete the measurement is longer (see Figure 5). That is, the waiting time for preheating is about 20 seconds, the actual measurement time is about 10 seconds, and it takes about 30 seconds to complete the measurement.

[0005]

[Purpose of the invention]

 The main purpose of the present invention is to install the heater and the chip separately, i.e. to create a wider space between the long constriction at the front of the housing and the storage at the rear of the housing, and A tuned heating-type thermometer that can increase the heating speed and reduce waiting time by making it easier and easier to install the heater and installing a heater with a relatively large volume. It is to provide

[0006] Further, the present invention utilizes the fact that the heater and the chip are separately installed, so that when the heater is heated, the distance between the heater and the chip is short, so that it is possible to avoid a phenomenon in which a chip is erroneously determined. An object is to provide a heating-type thermometer.

[0007] Furthermore, according to the present invention, when the heater is heated to the inside of the housing, the energy absorbed from the measuring end portion is completely stored by combining with the synchronized heating effect of absorbing the body temperature of the human body from the measuring end portion. Heat is transmitted to the housing without being conducted into the housing, and is close to the temperature of the human body, but slightly lower than the temperature of the human body. Therefore, it is an object of the present invention to provide a synchronized heating type thermometer capable of accurately and quickly measuring a body temperature.

[0008]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention is a tuned heating thermometer having at least a housing, wherein a measurement end is provided in front of the housing, and an electric circuit control device is provided therein. On the other hand, one end of the double conductor connected to the electric circuit control device is connected to a chip fixed in the measuring end, and the elongated constriction formed on the front end and the rear of the housing is connected to the housing. A tuned heating thermometer characterized in that a heater having a larger volume can be used without being affected by the space of the housing by installing a heater inside the connection part connected between the parts. I will provide a.

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As disclosed in FIGS. 2 and 3, the tuned heating thermometer according to the present invention is provided with a measurement end 11 in front of a housing 1 and a storage section behind the housing 1. An electric circuit control device 5 is provided inside the electric circuit control device 13. The electric circuit control device 5 is connected to the chip 2 provided with the outer end of the double conductor 3 connected to the electric circuit control device 5 fixed in the measuring end 11. Connect.

One long stenosis portion 12 is provided between the front measurement end portion 11 and the rear storage portion 13 of the housing 1, and a connection portion connected between the stenosis portion 12 and the rear storage portion 13 is provided. The heater 4 is installed on the inner wall. The heater 4 is connected to the electric circuit control device 5 by a wire 41, and the heater 4 is installed by using a relatively large space between the heater 4 and the heater 4. If a large heater can be installed, the heating speed can be improved at the same time.

When the heater 4 is heated by separately installing the heater 4 and the chip 2, since both are installed at a short distance, it is possible to avoid a phenomenon in which the chip 2 makes an erroneous determination. Further, when the heater 4 heats the inside of the housing 1, the temperature of the housing 1 is relatively low by combining with the synchronized heating effect of absorbing the body temperature of the human body from the measuring end 11, and the absorption from the measuring end 11. The flow of energy does not occur in the housing 1 due to the effect of the temperature difference. In addition, by heating the housing 1 to a temperature that is almost close to the temperature of the human body but slightly lower than the temperature of the human body, it is possible to avoid absorbing re-energy from the measurement end of the housing 1, so that accurate measurement is possible. And the body temperature can be measured quickly.

As shown in FIG. 2, the measuring end 11 absorbs the energy of the human body, and the inside of the housing 1 is heated by using the heater 4, so that the measuring end 11 and the housing 1 are connected to each other. Since the effect of the temperature difference between the electrodes can be remarkably reduced, the energy inside the measuring end 11 is not absorbed by the housing 1 and when the thermometer is turned on, the temperature is first sensed by the chip 2. After that, the heating temperature and the heating time are determined according to the temperature. When the temperature of the housing 1 is almost close to the temperature of the human body, but is slightly lower than the temperature of the human body (about 35 ° C.), the heating of the heater 4 is immediately stopped, so that the thermometer of the present invention is turned on. You can immediately measure your body temperature. This measurement can be completed in only 10 seconds (see FIG. 6). As a result, it can be seen that the temperature measurement time of the present invention is short.
