[Conventional technology and its problems]

Generally, younger people tend to have better blood circulation and higher skin temperature, but it is not common to use skin temperature as an index for beauty. It is considered that this is because the skin temperature slightly changes depending on the environmental temperature and the physical condition, and a skin thermometer with excellent performance capable of detecting the slight change has not been developed. For example, an ordinary thermometer (temperature sensor) may be diverted to measure the skin temperature, but the measured value by such a thermometer is not objective because it is affected by room temperature and the like. The skin could not be evaluated based on these measured values.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an objective skin temperature measuring method that can be used as an index for beauty counseling and an apparatus used therefor.

That is, according to the present invention, the skin temperature sensing portion of the measuring tool can be pressed against the skin surface with a constant contact pressure, and furthermore, the conductor is exposed at the center of the skin temperature sensing portion, and the thermoelectricity is applied to the conductor. Since the skin temperature is measured by connecting the pair, it is possible to accurately measure the objective skin temperature which is not affected by the room temperature or the like. Then, the measured skin temperature is not displayed as it is, but based on a special unit system obtained by dividing the upper and lower limits of the skin temperature at intervals finer than 0.1 ° C. Since it is converted and digitally displayed as a special converted value, the subtle temperature difference is magnified and digitized, and data that can be easily grasped as an index of beauty counseling can be obtained. Moreover, the device is divided into a main body part having a display part and a rod-shaped measuring tool, and the measuring tool is detachably fitted and held in the concave portion of the upper surface of the main body part, and the measuring tool is only used when necessary.

When not in use, the tip of the measuring tool is housed in the recess of the main body, so that the part is not damaged or unclean. Moreover, since the price of the thermocouple is low, there is also an advantage that the device can be manufactured at low cost.

Next, the present invention will be described in detail based on examples.

[Embodiment] FIG. 1 shows an embodiment of the skin temperature measuring apparatus according to the present invention. This device has a rod-shaped measuring tool 1 whose tip is formed in a sensing portion 1a for sensing skin temperature, and this measuring tool 1
And a main body 2 having a concave portion 2a into which the tip of the above can be inserted and held. The main body 2 has a built-in predetermined processing circuit for processing the sensing data from the measuring tool 1, and the processing result is displayed by the display means 3 attached to the front surface of the main body 2. It is getting done. Reference numerals 4 are switches for instructing various operations and turning on / off the power source.

As shown in FIG. 2, the measuring tool 1 includes a pencil-shaped casing 10 and a compression spring at the tip of the casing 10.
A resin sleeve (12) is attached to the sleeve (11) while being pressed and urged to the outside, and a resin sensing disk (13) fitted from the inside to the tip of the sleeve (12).
As shown in FIG. 3, an iron plate 14 bent in a U-shape is embedded in the sensing disk 13 with its central bent portion 14a exposed to the outside. This central bent portion 14a is pressed against the skin and functions to detect the skin temperature. Also, the bent end portions 14 of the iron plate 14 are
The b is integrally attached by welding to the outer surface of the iron small disc 15 fitted into the inner step portion 12a of the sleeve 12.
On the inner surface of this small disc 15, there are alumel wire 16 and chromel wire.
One end of 17 is connected by soldering.
The other ends of the wires 16, 17 are attached to the elongated substrate 18 extending axially in the casing 10 by soldering. In this way, an alumel-chromel thermocouple circuit is formed in the casing 10. Reference numeral 19 is a guide for fixing the substrate 18 in the casing 10, and 20 is a hand switch for applying a current to the thermocouple circuit to sense the temperature. A change in thermoelectromotive force generated in the thermocouple circuit is transmitted as an electric signal into the main body 2 through the cord 50 connected to the upper end side of the substrate 18. Therefore, when the hand switch 20 of the measuring tool 1 is turned on and the tip of the sleeve 12 is pressed against the skin, the central bent portion 14a of the iron plate 14 exposed at the tip of the sleeve 12 changes to the skin temperature, which is the whole iron plate 14. As a result, a thermoelectromotive force corresponding to this change is generated in the thermocouple circuit connected to this. This thermoelectromotive force is transmitted to the inside of the main body 2 by the cord 50. However, in order to accurately measure the amount of thermoelectromotive force, the central bent portion 14a of the iron plate 14 must be at the same temperature as the skin temperature, so that the skin has sufficient time to warm the central bent portion 14a. It is necessary to press the iron plate 14a.
For this reason, a buzzer mechanism (not shown) is attached to the inside of the casing 10 so that the buzzer keeps sounding until the time required for accurate measurement of the thermoelectromotive force elapses.

In addition, 21 is a cord 50 pulled out of the casing 10.
Is a connecting cord that is connected to the main body 2 in a bundled state, and is formed in a coil shape so that the measuring tool 1 can be easily handled (see FIG. 1). A plurality of annular grooves 23 are formed in parallel on the outer peripheral surface of the casing 10 in the vicinity of the hand switch 20 to form an uneven surface. This acts as a non-slip when the measuring tool 1 is gripped.

On the other hand, as shown in FIG. 4, the main body portion 2 is provided with a concave portion 25 into which the tip portion of the measuring tool 1 is inserted and held. The opening edge portion 26 of the recess 2a is slightly raised, so that it is difficult for dust and dirt to enter the recess 2a from the surroundings. Further, the upper end opening of the recess 2a is formed to be significantly larger than the outer diameter of the measuring instrument 1 to be inserted, and this opening is formed in the mortar-shaped portion 25 so that the opening is gradually reduced in diameter downward. . The mortar-shaped portion 25 is provided so that the switch 20 protruding outside the casing 10 and the iron plate 14 as the measuring portion do not come into contact with the inner wall surface of the recess 2a when the tip of the measuring tool 1 is inserted. Even if the measuring tool 1 is inserted from any direction, the switch 20 or the iron plate 14 and the concave portion 2a do not hit each other and one of them is not damaged. Then, the first inner wall 28 formed to have a smaller diameter by the gentle step 27 formed on the lower side of the mortar-shaped portion 25 guides the outer circumference of the casing 10 of the measuring tool 1, The step 29 below it supports the casing 10.
The second inner wall 30 extending downward from the step 29 guides the outer circumference of the sleeve 12 of the measuring tool 1, and the step 31 below the second inner wall 30 supports the sleeve 12. As described above, the casing 10 and the sleeve 12 are simultaneously supported by the two steps 29 and 31 in a state where the elongated rod-shaped measuring tool 1 is inserted into the main body 2 when only one side is supported. This is because it tends to rattle horizontally.

In addition, as shown in FIG.
Reading means 40 for reading data of thermoelectromotive force generated in the thermocouple circuit in the measuring tool 1, an amplifier 41 for amplifying an output signal from the reading means 40, and an analog output from the amplifier 41 is converted into a digital output. And a converter 42 for calculating the converted digital output signal and outputting the skin temperature sensed by the measuring tool 1 as a numerical signal.
43 and are provided. However, when the skin temperature is used as a numerical signal, the skin temperature is not digitized as it is, but when the skin temperature is 35.0 ° C, it is displayed as "20.0", and when it is 38.0 ° C, it is displayed as "40.0", and the interval between them is 0.1. Each is divided into a predetermined numerical value. Therefore, 0.1 in the above numerical value is 0.015 ° C. when converted into a normal temperature of Celsius, and a subtle temperature difference can be expressed as a clear numerical difference. Display means 3 for replacing the numerical signal converted in this way with a visual digital display is provided on the front surface of the main body 2 (see FIG. 1).

Using this skin temperature measuring device, the skin temperature can be measured, for example, as follows. First, the measuring tool 1 is pulled out from the recess 2a of the main body 2 and the power switch of the main body 2 is turned on. Then, the switch 20 on hand of the measuring tool 1
The ambient temperature is measured by putting in and leaving the measuring tool 1 released until the buzzer finishes sounding. The measured ambient temperature is displayed numerically by the display means 3 of the main body 2. Next, the tip of the measuring tool 1 is pressed against a predetermined position (for example, cheek) on the face, and this is maintained at a constant strength until the buzzer finishes ringing. As a result, the display of the display means 3 changes to the sensed skin temperature. Therefore, the measurer can sequentially read the environmental temperature and the skin temperature. Note that, as described above, the skin temperature displayed on the display means 3 is a special conversion value that is devised so that a subtle difference in temperature is large unlike the normal temperature in degrees Celsius.

As described above, according to this skin temperature measuring device, since the sensing unit that senses the skin temperature is elastically attached to the tip of the measurement tool 1 by the compression spring 11, Even if the pressing method of the measuring tool 1 changes due to a slight angle inclination, the sensing unit is always pressed with a constant contact pressure. Therefore, the skin temperature measurements are very accurate. Since the conductor portion for sensing the skin temperature is formed by the iron plate 14 exposed in a small area in the center of the sensing portion, the heat capacity of this portion is small and easily changes to the same temperature as the skin temperature. It is easily pressed against the skin. Therefore, the time required for sensing the skin temperature is short, and in addition to the elasticity of the sensing unit,
There is no deviation in its value. Then, the value is indicated by the special conversion value, and the delicate temperature difference is expressed as a large numerical difference, so that the skin temperature slightly different for each person is accurately indicated. Further, this device has an advantage that the input operation is simple and can be manufactured at a lower cost than that using a temperature sensor or the like. Further, since the tip sensing portion of the measuring tool 1 is made of resin except for the iron plate 14 exposed in a small area, unlike the case of metal or the like, the skin temperature may be deprived to be sensed lower than it actually is. Absent. Also, when pressed, there is no feeling of coldness or discomfort like metal, and no extra tension is given to the measurer. Furthermore, the measuring tool 1 is rod-shaped and easy to grip, and the operation of pressing it against a predetermined site can be easily performed. Moreover, when not in use, the tip of the measuring tool 1 can be fitted and held in the concave portion 2a of the main body 2 so that the tip of the measuring tool 1 is not damaged or becomes unsanitary. Very convenient to handle.

Therefore, we installed this device at the store of cosmetics stores,
If you prepare a numerical table (see the table below) showing the skin temperature of healthy skin according to age and environmental temperature by sampling in advance, the clerk can easily measure the customer's skin temperature and refer to this table. Since it is possible to evaluate the skin condition of the customer, cosmetic counseling according to the skin of the customer can be performed, cosmetics suitable for the customer can be recommended, and appropriate service can be provided.

In addition, in the said Example, although an alumel wire and a chromel wire are used as a metal wire for comprising a thermocouple circuit, in addition to this, platinum wire-platinum rhodium wire, iron wire-constantan wire, copper wire- A combination of constantan wires or the like may be used. However, since the combination of the above-mentioned alumel wire and chromel wire is the most excellent in sensing accuracy with respect to temperature, this combination can be said to be optimal.

Further, in the above embodiment, in the arithmetic circuit 43, the skin temperature
35.0 ° C is converted to 20.0 and 38.0 ° C is converted to 40.0 so that the temperature range of 3 ° C can be divided into 200 equal parts for display. However, the above numerical conversion must be a conversion that can be displayed finer than 0.1 ° C. It does not matter how many divisions and conversions are performed.

The display means 3 is adapted to display numerical values. However, in addition to the numerical display, appropriate advice according to the measurement result may be displayed in text. In addition, the numerical values in the above table are input in advance, and the processing circuit in the main unit 2 compares the numerical values with the measured values and the characters such as "HIGH", "NORMAL", and "LOW" are displayed together. It may be done. In addition to the visual display, the measurement value and the advice may be output by voice.

〔The invention's effect〕

As described above, the skin temperature measuring method for cosmetic counseling of the present invention is different from the conventional one, because the elastically attached sensing unit is pressed against the skin, so that the sensing unit for the skin does not depend on the pressing condition. The contact pressure becomes constant. Further, since the skin temperature is sensed by the thermocouple, it is possible to obtain an objective skin temperature which is not affected by the environmental temperature by a simple operation. Therefore, by measuring the environmental temperature at the time of measuring the skin temperature and the skin temperature, the skin temperature can be used as a beauty index in relation to the environmental temperature. Moreover, the measured skin temperature is not displayed as it is, but based on a special unit system obtained by dividing the upper limit value and the lower limit value of the skin temperature at intervals finer than 0.1 ° C. Since it is converted and digitally displayed as a special converted value, the subtle temperature difference is magnified and digitized, and data that can be easily grasped as an index of beauty counseling can be obtained. Then, the device of the present invention is divided into a main body section having a display section and a rod-shaped measuring tool, and the measuring tool is
In the recess on the upper surface of the main body, detachably fit and hold, remove the measuring tool only when necessary and press it against the target site, so that the skin temperature at that site can be measured. Very easy to handle. When not in use, the tip of the measuring tool is housed in the recess of the main body, so that the part is not damaged or unclean. And, it has an advantage that the manufacturing cost is low.
