Abstract

PURPOSE:To obtain an electronic thermometer which enables easy checking of temperature display during the measurement along with a higher temperature inspecting accuracy, by providing a temperature display element on a surface crossing axis center of a temperature measuring section, which contains a temperature measuring sensor, at a specified angle. CONSTITUTION:A body 1 has a temperature measuring section 1a and a sell section 1b integral formed in a T shape. A temperature measuring sensor 2 is built into the tip of the temperature measuring section 1a which a temperature display element 3 and a power source switch 4 are done into the shell section 1b on the surface perpendicular to the axis center of the temperature measuring section 1a. Then, temperature display elements 3 or the like such as liquid crystal are mounted on both surfaces of a measuring circuit substrate 6. With such as arrangement, when the bodily temperature is measured under an arm pit, the element 3 comes out on the front of a human body thereby enabling easy reading of an indication of the element 3 from the front while a rise in the temperature can be checked with removing the thermometer. This achieves a higher temperature inspecting accuracy with accurate measurement of the bodily temperature.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an electronic thermometer in which a temperature measurement sensor and a temperature display element are integrated into an exterior body.

(Prior Art) Currently, electronic thermometers, which are superior in safety, are becoming popular as an alternative to mercury glass thermometers, which have the porosity of mercury and the risk of glass breakage. This kind of integrated type that incorporates the temperature display element 102 and the temperature measurement sensor 103, and the fifth
A main body 20 incorporating a temperature display element 202 as shown in the figure
Temperature measurement sensor in 1? It can be roughly divided into a separate type in which a temperature measuring section 204 incorporating a temperature measuring section 203 is electrically connected with a flexible cape/I/205.

The former integrated type is designed based on the shape of a conventional mercury glass thermometer, and consists of a body part 101a and a temperature measuring part 1 (
Hb is arranged in a straight line, and the temperature display element 102 is attached to the side surface of the body portion 101a.

The latter separated type is designed to imitate the shape of a conventional industrial thermometer, and is designed to increase the degree of freedom in measurement by connecting the temperature measuring section 204 to the main body 201 with a cable 205. .

By the way, a separate type electronic thermometer does not touch the main body 20 while measuring body temperature.
1 must be held by some means and handling is troublesome, so at present, the integrated electronic thermometer shown in FIG. 4 is the mainstream.

(Problems to be Solved by the Invention) In the conventional integrated electronic thermometer described above, since the display element 102 is incorporated into the side surface of the body portion 101a,
When measuring body temperature under the armpit, there is a problem in that the display element 102 is located between the arm and the bridge, making the display difficult to read. Moreover, when checking for a rise in the temperature display during body temperature measurement, the display is difficult to read, so it is necessary to remove the thermometer from the armpit and take a look at it. There is a problem that causes this.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an electronic thermometer that can easily confirm the temperature display during body temperature measurement and can improve the accuracy of temperature measurement.

[Structure of the Invention (Means and Effects for Solving Problems)] The electronic thermometer of the present invention has a surface that intersects at a predetermined angle with the axis of the temperature measuring part incorporating the temperature measuring sensor (this temperature display element is The device is designed so that the display surface faces the person to be measured during body temperature measurement.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, reference numeral 1 denotes a main body in which a temperature measuring part 1a and a body part 1b are integrally formed in a single character shape, and a temperature measuring sensor 2 is incorporated in the tip of the temperature measuring part 1a, and A temperature display element 3 and a power switch 4 are incorporated in a surface perpendicular to the axis of the temperature measuring section 1a.

As shown in FIG. 2, the lead wire terminals 5 from the 1 inch centimeter 2 and the measurement circuit board 6 are incorporated into the body part 1b, and the measurement circuit board 6 is fixed to the body part 1b by a decorative lid 7. The screen surface of the measurement circuit board 6 has a temperature display element 3 such as a liquid crystal. Battery 8. Electronic components such as a variable resistor 9 for adjusting measurement characteristics and an integrated circuit are attached.

By the way, since the above-mentioned electronic thermometer has inherent variations in the temperature measurement top 2 itself, it is necessary to perform temperature calibration during the manufacturing process.

In this case, the variable resistor 9 for adjusting measurement characteristics can be adjusted while checking the temperature displayed on the temperature display element 3 with the temperature measurement section 1a inserted into a calibration water tank maintained at a reference temperature. . After completing this temperature calibration, remove the decorative lid 7 from the body part 1b.
By fixing with screws or the like, the electronic thermometer shown in FIG. 1 is completed.

In the electronic thermometer configured as described above, the display element 3 is provided on a surface perpendicular to the axis of the temperature measuring part 1a, so when measuring body temperature under the armpit, the display element 3 is placed on the front side of the human body. Since the display on the display element 3 can be easily read from the front and the temperature rise can be confirmed without removing the thermometer, the body temperature can be accurately measured and the accuracy of temperature measurement can be improved.

Furthermore, when the electronic thermometer is inserted into the calibration water tank during calibration work, the body portion 1b faces upward, allowing the measurement circuit board 6 to be stably held, and the variable resistor 9 for adjusting measurement characteristics can be easily adjusted on the top surface. can do.

FIG. 3 shows another embodiment of the present invention, in which a temperature measuring section 11a incorporating a temperature measuring sensor 2 and a body section 11b are integrally formed in a single shape, and the axis of the temperature measuring section 11a and the body section 11b are integrally formed. A temperature display element 3 is incorporated in one side of the body portion 11b that intersects at a predetermined angle and faces, for example, the person to be measured.

In an electronic thermometer with such a configuration, when measuring body temperature by placing the temperature measuring part 11a under the armpit, the display element 8 faces toward the person to be measured, so that the display element 8 can be viewed directly and the displayed contents can be easily read. be able to.

Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without changing the gist. For example, a body part incorporating a temperature display element is rotatably provided in a temperature measurement part incorporating a temperature measurement sensor,
The temperature display element can also be made to intersect at a desired angle with respect to the axis of the temperature measuring section.

[Effects of the Invention] According to the present invention, an electronic thermometer is provided that allows the temperature display element to be viewed directly during body temperature measurement, making it easy to check the temperature display, as well as being able to accurately measure one point without removing the thermometer and increasing the temperature measured. can be provided.
