Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an electronic thermometer, and particularly to an electronic thermometer in which a temperature-sensing section having a temperature-sensing element can be separated from a main body.

<Summary of the Invention> The electronic thermometer of the present invention is an electronic thermometer in which the temperature-sensing part and the main body part can be separated, in which a connector part for connecting the temperature-sensing part is separated from the main body part, and the connector part is separated from the main body part. Temperature information from the temperature-sensing section can be displayed with a single button via the button section provided on the screen.

<Prior art and its problems> In general, electronic thermometers, especially electronic thermometers, are known in which a temperature-sensing part having a temperature-sensing element and a body part that measures and displays temperature based on a signal from the temperature-sensing element can be separated. It is.

Conventional thermometers of this type include, for example, Japanese Patent Application Laid-Open No. 55-5442.
As shown in Japanese Patent No. 2, there is a device in which the lead wire of the temperature sensing section is held inside the jaws of the pin-like structure of the main body. However, this thermometer is inconvenient to operate due to its pincer-like structure, and there have been drawbacks such as inaccurate temperature readings due to poor connection between the electrodes on the main body and the lead wires of the temperature sensing section.

Furthermore, when this thermometer is used in a hospital, the patient must grasp the temperature-sensing part while holding it in his/her mouth, which has the disadvantage of giving the patient, especially children, a sense of fear due to its pincer-like shape.

Additionally, the overall shape of the main body is large due to its structure.

It is also heavy in weight. Holding this heavy and large main body with one hand, especially when carrying out group temperature measurement, etc., causes a great deal of physical fatigue for the person taking the temperature (user).

<Purpose of the Invention> The present invention has been made in view of the above-mentioned circumstances, and it is possible to separate and independent the connector part from the main body part so that temperature can be measured by holding only the connector part with one hand and with one button operation. Therefore, it is an object of the present invention to provide an electronic thermometer that reduces physical fatigue when using the thermometer.

<Structure and Effects of the Invention> In order to achieve the above object, the present invention includes a connector part in which a temperature-sensing section equipped with a temperature-sensing element is detachably attached, and a main body part connected to the connector part via a cord. The connector section is provided with a device for disconnecting the current to the temperature sensing section.
It is characterized by having a button section for taking in temperature information.

According to the present invention, the connector portion is separated and independent from the main body portion, and the button portion is provided on the connector portion.

Since the temperature can be measured with a single button, you only need to hold the lightweight and compact connector when measuring the temperature, which significantly reduces the physical fatigue associated with conventional methods when measuring temperature. This improves operability.1. It has a remarkable effect when taking a group temperature measurement for my younger sister.

It also has the effect of not giving the test subject a sense of fear, unlike conventional electronic thermometers with a pincer-like structure.

<Description of Examples> Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of an electronic thermometer according to an embodiment of the present invention.

In FIG. 1, reference numeral 10 denotes a temperature sensing portion having a circular cross section and having a temperature sensing element 10a such as a thermistor at its tip. Reference numeral 20 denotes a connector section to which the temperature sensing section 10 can be attached and detached, as will be described later, and this connector section is made separate and independent from the main body section, which has conventionally been integrally constructed. Reference numeral 30 denotes a main body portion from which the connector portion 20 is separated, and this main body portion 30 is electrically connected to the connector portion 20 via a cord 40.

The connector part 20 has a button 21 and a temperature display part 22.
As shown by the dashed line in FIG. 5, the first contact 51. Temperature measurement connected to the second contact 52
An electric circuit E formed by connecting a control section 53 (processing the signal from the temperature sensing element 10a of the temperature sensing section 10) and a display section 22 that displays the temperature output from the temperature measurement/control section 53. is incorporated.

Further, a power supply section 54 shown in FIG. 5 is disposed inside the main body section 30, and is connected to the electric circuit F via a cord 40.

As shown in FIG. 2(A), the temperature sensing part 10 in FIG. 1 has a lead part 1 formed on the side surface opposite to the temperature sensing element 10a.
0b and a lead portion 10C formed on the end face are provided, and the lead portion 10b and the IOC are connected to both ends of the temperature sensing element 10a via sealed lead wires 10d, respectively.

It is connected to a rod 23 provided at the bottom. A second contact 52 is formed at the lower end of this rod 23 to connect to a conductive member 23a provided on the surface thereof. The bush button 21 and the rod 23 that constitute the button part are movable in the vertical direction within the connector part 20.
It is biased upward by a spring 24. Note that the upper positions of the bush button 21 and the rod 24 are regulated by a stopper 20aK formed on the connector portion 20.

The lower end of the rod 23, that is, the contact 52 is connected to the connector portion 20.
Through the through hole 20b of the temperature sensing section 1, it is possible to penetrate into the temperature sensing section insertion hole 25 (which will be described later) (perpendicularly).
This corresponds to the lead portion 10b on the end face of No. 0.

A sliding contact 26 is always in sliding contact with a conductive member 23a provided in electrical connection with the contact 52 of the rod 23, and the sliding contact 26 is placed inside the connector portion 20. It is connected to the electric circuit E that is connected thereto.

In the left and right direction in FIG.
A temperature-sensing part insertion opening 25 is formed to insert a temperature sensing part of 0b, 10cmIk, and a first contact 51 is provided at the abutting part of this temperature-sensing part insertion opening 25. And this first contact point 5
1 is connected to the electric circuit E.

In the above configuration, the temperature sensing section 10? Before being attached to the connector section 20, the rod 23 is not inserted into the temperature sensing section insertion opening 25 due to the spring 24. When attaching the temperature sensing section 10, the lead portion 10b of the temperature sensing section 10 is attached.

10C is inserted into the temperature sensing part insertion port 25, and the lead part 10c on the end surface is brought into contact with the contact 51 on the abutting part. Next, when the button 21 is pressed down with a finger or the like against the spring 24, the contact point 52 of the rod 23 comes into contact with the lead part 10b on the side surface of the temperature sensing part 10. Therefore, temperature sensing part 1
The temperature sensing element 10g of No. 0 is connected to the electric circuit E of the connector portion 20 via one lead portion 10b → second contact 52 → conductive member 23a → sliding contact 26. We have explained how to install it, but instead
A flat temperature sensing section 11 as shown in Figure (B) can also be attached. In this case, the lead portion 11 on the side surface of the temperature sensing portion 11
By providing b on both the front and back surfaces, the temperature sensing section 11 can be attached regardless of whether it is on the front or back.

Furthermore, in the embodiment described above, the contact 52 of the rod 23 was brought into contact with the lead part 10b on the side surface of the temperature sensing part 10;
Instead, as shown in FIG. 4, the rod 23 is provided with a hole 23a for passing through the temperature sensing part, and a contact 51a is formed in this hole 23a.
It may also be configured such that the lead portion 10b of the temperature sensing portion 10 is brought into contact with the lead portion 10b. In this case, the hole 23a of the rod 23 serves as a locking mechanism for the bush button 21, which is convenient.

In addition, it goes without saying that the internal structure of the connector section 20 can be modified in various ways depending on the configuration of the temperature sensing section 10. In addition, in the embodiment described above, the electrical circuit E shown in FIG. 5 is built into the connector section 20. , the case where only the power supply section 54 is built into the main body section 30 has been described, but as shown in FIG.
Electric circuit E1 consisting of temperature measurement/control section 53 and power supply section 54
is built into the main body part 30, and the display part 22 is built into the connector part 20.
It is also possible to incorporate only the following circuit. In this case, there is an advantage that the connector section 20 can be further reduced in size and weight.

Although the temperature display section 22 is provided in the connector section 20 in FIG. 1, it may be provided in the main body section 30.
