Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a sun protection device for preventing sunburn due to ultraviolet rays.

[Prior art and its problems]

Conventionally, sun cream, sun oil, sunshade, etc. are generally applied to prevent sunburn due to ultraviolet rays, but the amount of ultraviolet rays actually received by an ultraviolet sensor etc. is measured to warn against overburning of the skin. A device for doing so is also considered. In this type of device, the measured ultraviolet ray amount is sequentially accumulated, and when this accumulated data approaches the value causing sunburn or reaches the value causing sunburn, an alarm sound is issued and a warning is issued. It has become.
Further, in the above-mentioned sun cream, sun oil, etc., various kinds of sun protection factors (SPFs) having different protective effect indexes for protecting the skin from ultraviolet rays, that is, various kinds, have been commercialized. Due to the difference in the amount of UV rays, the amount of ultraviolet rays required to reach the same degree of sunburn will be different.

By the way, the amount of ultraviolet rays that causes sunburn varies depending on the degree of skin strength to ultraviolet rays, and the degree of skin strength can be classified into several types as skin types. FIG. 4 is a table showing the classification contents of each type when the degree of skin strength to ultraviolet rays is classified into 6 types of skin. In this table, the skin types are classified into six types, from the skin type I, which is the weakest against ultraviolet rays, to the type VI, which is the strongest skin.

However, there is a big difference in the SPF value of the sun cream etc. used and the amount of ultraviolet rays until sunburn occurs depending on the type of skin. Therefore, in order to warn properly not to have a transient sunburn, the above device is provided. However, it is considered that the SPF value and the skin type can be input and an alarm sound is generated when an ultraviolet ray amount corresponding to the SPF value is received. For example, in USP 4535244, the SPF value of sun cream or the like and the strength value of the skin are input and stored, and the cumulative data of the measured ultraviolet ray amount is based on the SPF value and the strength of the skin. A device is described which, when a specific value is reached, sounds an alarm and warns of overburning.

However, in this type of device, the alarm sound is generated when it becomes a standard burning condition, and therefore, the alarm warning sound corresponding to the burning condition of the skin is generated for the user. It had the drawback of not being able to. That is, with respect to the degree of skin burning, it is often the case that the user does not have a sunburn, burns lightly, or browns the skin for different purposes for each user. Has a drawback that it cannot satisfy these requirements.

[Purpose of device]

The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a sunburn preventing device that notifies the user of a plurality of burns.

[Key points of device]

The present invention inputs the sun protection factor and the data corresponding to the strength and weakness of the skin against ultraviolet rays, and based on these data, obtains the ultraviolet ray amount data corresponding to a plurality of burning conditions and notifies the ultraviolet ray amount data. It is a thing.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram showing the overall configuration of a sunburn prevention device of one embodiment. The oscillator 1 generates a clock signal having a basic frequency and outputs it to the frequency dividing circuit 2. The frequency dividing circuit 2 divides the clock signal to generate a clock signal having a cycle of 1 second, and outputs it to the clock counting unit 3. The clock signal is also output to the AND gate 23. The clock counting unit 3 includes a day of the week, date, hour, minute, and second counter, counts the clock signal to obtain time data, and outputs the time data to the driver 5 via the gate 4. The driver 5 creates a display signal from the time data and displays it on the time display portion 6a of the display unit 6. The display 6 includes a time display section 6a for displaying the current time such as "day of the week, date, hour, minute, second", SPF value, skin type or ultraviolet ray measurement time, and a three-stage skin burn condition described later. It is composed of an ultraviolet ray amount display section 6b composed of 30 display bodies for displaying the amount of ultraviolet rays corresponding to the sunburn and an ultraviolet ray quantity display section 6c composed of 30 display bodies for displaying the measured cumulative ultraviolet rays. .

FIG. 5 is a table showing the amount of ultraviolet rays causing sunburn depending on the skin type, SPF value and degree of tanning. This table shows that the SPF value is "0", that is, a person with skin type I has a wheat-colored tan (corresponding to the degree of tanning B) without application "7 J / c
When the ultraviolet ray amount of "m ² " is set to "1", it shows how many times the ultraviolet ray amount receives the same degree of sunburn.
Comparing only the degree of scalding B, when using sun cream having an SPF value of “2”, the amount of ultraviolet rays that causes sunburn in people with type I skin is “2” The amount of UV rays that causes sunburn in Type VI people is "16", and there is an 8-fold difference between the two values. Also,
For people with type III skin, the SPF value is "1", that is, the amount of ultraviolet rays that causes sunburn when not applied is "2", whereas when using sun cream with an SPF value of "15" The amount of ultraviolet rays that causes is "30", and there is a 15-fold difference between the two values.

In addition, as shown in FIG. 5, each of the three stages of burnt conditions, that is, burnt condition A that causes almost no sunburn, moderate burnt condition B of wheat color, and maximum burnt condition C that does not pose any danger, is shown. When comparing the amount of ultraviolet rays, which is the condition, for example, when a person with skin type III uses sun cream with an SPF value of "4", there are three levels of "A",
The amount of ultraviolet rays to be "B" and "C" is "4",
It becomes "8" and "12".

However, one display member of the ultraviolet ray quantity display portions 6b and 6c in FIG. 1 has the ultraviolet ray quantity “1” (7 J / c) shown in the table of FIG.
Corresponding to m ² ), for example, if the amount of ultraviolet rays that is a predetermined sunburn that is determined by the SPF value, skin type, etc. is “6”, the sixth indicator of the ultraviolet ray amount display section 6b lights up and the sunburn occurs. Display the warning levels that occur.

The switch SW ₁ is a switch for switching between the time display mode and the ultraviolet ray measurement mode. Every time the switch SW ₁ is operated, a pulse signal is input from the one-shot circuit 7 to the T input terminal of the flip-flop 8 and the output of the flip-flop 8 is inverted. To do.

Now, when the Q output signal of the flip-flop 8 becomes high level by operating the switch SW _1, the time display mode is set. In the time display mode, the gate 4 is opened, the time data is output from the total clock section 3 to the driver 5, and the current time is displayed on the time display section 6a of the display unit 6.

When the switch SW ₁ is operated in this state, the output force signal of the flip-flop 8 is inverted to the high level, the AND gates 9 and 10 are opened, and the ultraviolet mode is set. In the ultraviolet mode, the switch SW ₂ is a switch for switching between data setting such as skin type and ultraviolet amount measurement.
A pulse signal is given from the one-shot circuit 11 to the T input terminal of the flip-flop 12 every time W ₂ is operated,
The output of the flip-flop 12 is inverted and switched.

If the output signal of the flip-flop 12 becomes high level by operating the switch SW ₂ , the data setting state is set. At the time of data setting, the two inputs of the AND gate 10 become high level, and the output signal thereof becomes high level. This high level signal causes the AND gates 13 and 14
Open, and the operation signals of the switches SW ₃ and SW ₄ are SPF value storage unit 15 and type storage unit 16 configured by a counter or the like.
Input to each as a signal for data setting. That is, at the time of data setting, the switch SW ₃ functions as a switch for setting the SPF value, and the pulse signal from the one-shot circuit 17 generated at each operation of the switch SW ₃ causes the SPF value storage unit 15 to output the SPF value. (Corresponding to 5 types of S shown in FIG. 5 in this embodiment)
Codes corresponding to the PF value) are sequentially output. And
This code is output to the driver 5 through the gate 18 and the set SPF value is displayed on the left side of the time display portion 6a. Further, this code is also output to the decoder section 19.

Further, the switch SW ₄ functions as a switch for setting the skin type when setting data. That is, the one-shot circuit 20 that is generated each time the switch SW ₄ is operated.
In response to the pulse signal from, the type storage unit 16 sequentially outputs codes corresponding to skin types (in the present embodiment, codes corresponding to six types of skin). Then, this code is simultaneously output to the driver 5 through the gate 18 and displayed as the skin type set in the time display section 6a. The output of the type storage unit 16 is the decoder unit 1
9 is also input, and the code indicating the set skin type is latched in the decoder unit 19.

The decoder unit 19 decodes the input SPF value and the code corresponding to the skin type, and determines the respective burning conditions determined by the set SPF value and skin type (in this embodiment, the three-step burning condition shown in FIG. 5). The ultraviolet ray amount data corresponding to () is output to the driver 31b. The driver 31b outputs a signal for lighting the corresponding display body from these data, and the ultraviolet ray amount display portion 6b displays the ultraviolet ray amounts corresponding to the three stages of burning.

When the switch SW ₂ is operated after the setting of the SPF value and the skin type is completed in this way, the data setting state is switched to the ultraviolet ray measuring state. That is, when the output of the flip-flop 12 is inverted by the operation of the switch SW ₂ and the Q output signal becomes high level, the two inputs of the AND gate 9 become high level and the AND gate 9 outputs a high level signal. This high-level signal opens the analog gate 21, and the operation of the switch SW ₃ starts or stops the ultraviolet ray measurement. That is, the switch SW ₃ functions as a measurement start / stop switch during ultraviolet ray measurement, and the pulse signal output from the one-shot circuit 17 every time the switch SW ₃ is operated passes through the AND gate 21 and is input to the T input terminal of the flip-flop 22. Input and invert its output state. Now, assuming that the switch SW ₃ is operated through the data setting state, the Q output signal of the flip-flop 22 becomes high level and the AND gate 23 opens to start the ultraviolet ray measurement. When the AND gate 23 is opened, the time measurement signal given from the frequency dividing circuit 2 is given to the time measuring unit 24 and the measurement of the measurement time is started. The measured time measured by the time measuring unit 24 is the gate 25
Is output to the driver 5 and is displayed on the clock display unit 6a as the ultraviolet ray measurement time. When the measurement is started, the minute signal obtained by counting the time signal from the timepiece measuring unit 24 is a measurement signal M, which is the sensor unit 26 and the amplifying unit 2.
7, output to the arithmetic unit 29, etc. to operate those circuits. The sensor unit 26 is a sensor that detects ultraviolet rays, and outputs the detected data to the amplification unit 27 each time the measurement signal M is given. The data amplified to a predetermined level by the amplifier 27 is converted into digital ultraviolet data by the A / D converter 28 and output to the calculator 29. The calculation unit 29 converts this ultraviolet ray data into ultraviolet ray amount data for one minute of the measurement interval, and further uses the converted value as the ultraviolet ray amount storage unit 3.
The accumulated ultraviolet ray amount data from the start of measurement output from 0 to that point is added, and the addition result is output to the ultraviolet ray amount storage unit 30 as new accumulated ultraviolet ray amount data. The accumulated ultraviolet ray amount data stored in the ultraviolet ray amount storage unit 30 is output to the driver 31c and displayed on the ultraviolet ray amount display unit 6c as the accumulated ultraviolet ray amount measured by the driver 31c.
FIG. 3 shows the display state when measuring the amount of ultraviolet rays. The time display section 6a of the display 6 displays the elapsed time “1 hour 58 minutes 20 seconds” from the start of ultraviolet ray measurement, and the upper row. The second, fourth, and sixth indicators b ₂ , b ₄ , b ₆ of the ultraviolet ray amount display section 6b of the above are respectively lit up, and the ultraviolet ray amount “2, 4, 6” corresponding to the three stages of burning is displayed. Is displayed. Further, the first to third display bodies c of the ultraviolet amount display section 6c in the lower stage

Also, when the switch SW ₃ is operated during the measurement of the UV, Q output of the flip-flop 22 is measured becomes inverted low level is canceled. That is, the flip-flop 22
When the Q output signal of becomes low level, the AND gate 23
Is closed, no time signal is supplied to the time measuring unit 24, and the clock measurement is stopped. 1 when the time measurement is stopped
The measurement signal M for each minute is also not output, and the sensor unit 26,
Ultraviolet ray measurement in the calculation unit 28 and the like is also stopped.

The switch SW ₄ during ultraviolet ray measuring functions as a reset switch, a pulse signal generated by the operation of the switch SW ₄ passes through the AND gate 32, the time measuring unit 24
And the respective circuits are given to the ultraviolet ray amount storage section 30 to reset the respective circuits to the initial state.

Next, FIG. 2 is a diagram for explaining the function of the decoder section 19. Each point on the grid indicates a signal level, a circled grid point indicates a high level signal, and an unmarked grid point indicates a low level signal. Show. For example, when “2” is set as the SPF value and “III” is set as the skin type, the decoder 41 outputs a signal for setting the grid point e ₁ at a high level, and the decoder 42 outputs the grid point f ₁ at a high level. The level signal is output. As a result, _d 1 on _{l 1} line _{l 1} is selected ~
A signal indicated by d _30, that is, only d ₂ , d ₄ , and d ₆ are at high level and the other signals are at low level are output to the driver 31b.
