Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a thermometer, and particularly to a structure suitable for digitally displaying body temperature.

[Conventional technology and problems]

In the past, there have been various products that have adopted digital displays to make it easier to see body temperature, but most of them have the disadvantage that the display area is very small compared to their external dimensions, which is far from the original purpose of making it easy to see. Ta. Moreover, since the horizontal center line of the probe and the center line of the display section almost coincide, when the probe is held on an extension of the probe, the fingertip hits the display section and the display is obstructed by the fingertip, making it difficult to see.
There are also devices in which the probe section and the display section are separated and the display section is enlarged, but these have disadvantages such as poor operability and the lead wire from the probe being easily broken.

An object of the present invention is to provide a thermometer in which the display portion is sufficiently large compared to the product's external shape without impairing operability by devising the configuration of each part.

[Means for solving problems]

In the present invention, when measuring body temperature under the armpit or under the tongue, if the shape of the probe including the temperature-sensing part is suitable for being held, the other display parts etc. are made elongated. This was done based on the fact that it is not necessary, and that when measuring under the armpit while wearing clothes, it is easier to operate if the length is shorter than the elongated shape, even if it is slightly wider. . Simply increasing the display size would increase both the width and length of the display, and if other circuit components and power batteries were placed in parallel on the same plane, both width and length would become too large to be practical. By shifting the horizontal center of the display section from the horizontal center of the probe section, space for circuit components other than the display section can be secured, and at the same time, the battery can be placed between the board and the other side of the display section. The above-mentioned object is achieved by minimizing the increase in the width direction and shortening the length at the same time by forming a laminated structure. In view of these points, the present invention provides a thermometer equipped with a display 2 that detects body temperature using a temperature sensor 9 disposed in a temperature sensing section at the tip of the probe section 24 and digitally displays the value. A slender probe part 24 is extended along the extension line of one side wall of the main body case 1 to which the probe part 2 is attached. Attach the display 2 to the main body case 1 so that the digital display on the display 2 is in an upright state when
The display device 2, the substrate 7 constituting the drive circuit, and the battery 8 for power supply thereof are arranged in a stacked structure such that the display device 2 and the battery 8 overlap with the substrate 7 in the middle.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a structural diagram of the digital display thermometer of the present invention. Similarly, FIG. 2 is a front view.
The tip of the main body case 1 extends into a tapered shape as a probe portion 24.
As shown in FIG. 2, it extends in a narrow shape along the extension line of one side wall of the main body case 1, and is formed to be offset with respect to the main body case 1. This probe part 2
A cap 13 is attached to the tip of 4 with an adhesive 14. A temperature sensing thermistor 9 is disposed inside the cap 13, and its lead wire passes through the probe and is soldered to the substrate 7. A liquid crystal display 2 is attached to the upper surface of the substrate 7 by a holder 3. The board 7 is inserted into the case from the rear end side of the main body case 1 and fixed by the back cover 10. A control LSI (not shown) is soldered to the opposite side of the substrate 7 from the liquid crystal display 2, and a battery 8 for power supply is arranged in an empty space on the same side. In addition, a circuit element (not shown) is disposed at the lower part of the same plane as the liquid crystal display 2. A display section 15 having a liquid crystal display 2 is disposed in the enlarged portion of the main body case 1 and is located away from the horizontal extension line of the probe. After turning on the power switch 4 and holding the probe tip under the armpit or under the tongue, the temperature value is displayed on the display 15 after a certain period of time. In this embodiment, a liquid crystal display with a character height of 10 mm is used. The horizontal center line 16 of the display section 15 is configured to be shifted upward by a large amount compared to the horizontal center line 17 of the tip of the probe.

This display device 2 is installed so that the digital display is in an upright state when one side wall extension line of the main body case 1 is turned downward.

Due to the above configuration, even though a large display with display characters approximately twice the height of a conventional thermometer is used, the liquid crystal display 2 is shifted upwards. , a space is created for arranging circuit elements at the bottom, and compared to the case where the liquid crystal display 2 and other circuit elements are arranged in series in the length direction, the increase in length is only due to the increase in the liquid crystal display 2. I can hold it down. Furthermore, by disposing the battery 8 on the back side of the liquid crystal display 2 and arranging the liquid crystal display 2, the substrate 7, and the battery 8 in a stacked manner, the increase in length due to the battery 8 can be reduced to zero. Ta. Therefore, the overall length can be reduced to approximately 2/3 compared to conventional digital display thermometers.

Therefore, when measuring body temperature under the armpit with clothes still on, operability is very good because the part protruding from the armpit is smaller than that of conventional digital display thermometers. Also, in the case of sublingual use, the overall center of gravity is close to the probe side, making it easier to hold.

In addition, in this embodiment, the width dimension 18 of the main body case 1 in the part where the liquid crystal display 2 is installed is greatly increased, but since the probe part has the same shape as a conventional thermometer, there is no problem in measurement. Not only does it not cause any problems, but when measuring the armpit, the convex part in the width direction hits the pectoralis major muscle at the upper part of the armpit and acts as a stopper, ensuring that the tip of the probe is always at the same position under the armpit, so it is easy to insert the probe into the armpit. This has the effect of not causing measurement errors due to excess or deficiency.

Note that the battery position is not limited to this as long as the display 2 and battery 8 have a laminated structure, and the position of the battery may vary depending on the type of display element, battery, substrate, and combination structure of cases used in this example. Of course, it is not limited to this.

[Effect]

The present invention provides a thermometer that is equipped with a display 2 that detects body temperature using a temperature sensor 9 disposed in a temperature sensing section at the tip of a probe section 24 and displays the value. A thin probe part 24 is extended along one side wall extension line, and the probe part 24 is formed to be biased toward the main body case 1, and when the extension line is on the lower side, the display Attach the display 2 to the main body case 1 so that the digital display 2 is in an upright position,
The display 2, the board 7 constituting the drive circuit, and the battery 8 for their power supply are arranged in a stacked structure so that the display 2 and battery 8 overlap with the board 7 in the middle. 8. The board 7 can be stored efficiently, and as a result, a large display section can be formed in the biased main body case 1, and the original easy-to-read effect of digital display can be fully utilized. Moreover, since the probe section 24 is formed to be biased toward the main body case 1, the display section will not hit your fingertips even if you hold it on the probe extension line, and the digital display will be erect when the extension line is on the lower side. The display section becomes easily visible.
