Mist Sprayer having Skin Condition Measuring Parts

The present invention is a mist device for supplying moisture to the skin, in particular, the skin condition measurement function that can maintain the user's skin in the best state by measuring the moisture state of the skin and determine the optimum amount of water supply and resupply time corresponding thereto It is related with the mist apparatus provided with.

In general, the structure of the skin is composed of three layers from the outer skin (epidermis, dermis and subcutaneous layer). The epidermis is located on the outermost side of the skin to prevent foreign substances from penetrating the body from the outside and to prevent water evaporation in the body, which varies depending on the part of the body but has a thickness of 1.1 mm on average. The dermis contains collagen, a collagen fiber, and elastin, an elastic fiber, to maintain the elasticity of the skin. The average thickness is about 2 mm, and when the dermis is damaged by ultraviolet rays, problems such as skin wrinkles occur. Subcutaneous tissue is a layer between the dermis, the muscles, and the skeletal structure in which the fibers from the dermis are loosely coupled. The thickness of the subcutaneous tissue varies depending on the site and shows a great difference according to gender and age.

One of the most important roles of the epidermis in such a skin structure is moisture control. Among the various layers of the epidermis, the stratum corneum inhibits the loss of water and electrolytes through the skin, which allows the skin to maintain its normal biological function. It provides the environment and serves as the first line of defense when harmful factors from the outside environment invade through the skin. The water content in the stratum corneum is the degree of skin hydration, and the moisture state of the skin varies from person to person, body part, and season, and maintaining optimal skin hydration is the first step in skin health.

In order to moisturize the skin, it is most basic to drink plenty of water continuously.In order to supply water to the stratum corneum of the epidermis, which is the outermost layer of the skin, the body consumes a considerable amount of water continuously. It is necessary to give.

However, it is difficult for busy modern people to have an environment where they can drink enough water when they need it.In particular, in urban areas, air is contaminated by car fumes and dust, which adversely affects the skin, resulting in more dry skin. You lose.

In consideration of these problems, a device for directly supplying moisture to the skin has been popularized.

There was a problem that only the device can be used.

In addition, the conventional mist device has a problem that the injection amount is determined uniformly, and the prescribed injection amount is also a predetermined amount without sufficient research or medical basis, so that it is difficult to adequately supply a necessary amount of water suitable for the current state of the skin.

On the other hand, even if the skin is sufficiently supplied with moisture, it is necessary to supply the water from time to time by natural evaporation, etc. In the daily life of busy modern people, the concentration of water is often overlooked.

1 and 2, the mist device having a skin condition measuring function according to an embodiment of the present invention is a moisture measuring unit 100 for measuring the degree of hydration of the skin using an electrical signal therein, and The control unit 300 to grasp the user's current skin moisturizing state based on the information measured by the water measurement unit 100, the spray unit 200 to atomize the aqueous solution using a vibrator and to spray the user's skin, and the The aqueous solution storage container 12 for storing the aqueous solution supplied to the spray unit 200 is provided, and the display unit 400 for displaying a variety of information, such as the user's skin moisturizing state on the outside of the device, and drives each device The operation button 11 and the like are provided to make.

On the other hand, the skin hydration is measured using an electrical signal, a method using a microwave, a method using a near-infrared rays, a method using an MRI device, etc. Among them, a method of measuring by using an electrical signal is most widely used.

The method of measuring skin hydration using electrical signals is also divided into various methods.How to apply a sawtooth voltage having a variable frequency to the skin and measure the change in hydration of the skin surface according to the change of dielectric constant. A typical method is to apply a sine wave to the skin and measure its conductance to measure the moisture content of the stratum corneum.

In order to implement the present invention, it is obvious that the moisture measuring unit 100 may be configured using any of the above-mentioned methods, and may be selected in consideration of the size and use of the device. That is, when implementing a mist device having a skin condition measuring function according to the present invention in a form that a person carries and uses, a method for measuring skin hydration simply and quickly is provided in a hospital or a skin care room, and professionally. If you want to implement in the form of use, adopt a method that can make more accurate and accurate measurement.

In the present embodiment, a portable device that a user can carry and use frequently can be implemented. The method of measuring the amount of moisture retained in the stratum corneum by using a sine wave of low frequency is the most compact in terms of miniaturization of the device and the speed of measurement. Will be appropriate.

Therefore, in the present exemplary embodiment, the moisture measuring unit 100 is configured using the same method. Referring to FIG. 3 (a), the moisture measuring unit 100 outputs a sine wave having a constant frequency. The signal generator 110, the electrode unit 120 for applying and recovering the sine wave output from the signal generator 110, and the signal for processing the electrical signal recovered through the electrode unit 120 It is configured to include a processor 130.

In this case, the signal generator 110 is configured based on an oscillator device and an output controller for generating a low frequency sinusoidal signal of 100 kHz or less, and the signal processor 130 includes an amplifier, an inverter, a high band and a low band filter, and the like. It consists of. In addition, three electrodes of the electrode unit 120 are formed. The two electrodes are an R electrode (Reference Electrode) 121 and a C electrode (Current Carrying Electrode, 122) for applying and recovering a reference signal to the user's skin. One electrode is an M electrode (Measuring Electrode) 123 for measuring a reaction signal.

When the signal generator 110 generates a constant voltage sinusoidal signal having a constant frequency and is applied to the skin of the measurer through the R electrode 121 and the C electrode 122 of the electrode unit 120, the M electrode 123 is applied. The current responding to the impedance of the stratum corneum just below the contacting skin portion can be measured via the M electrode 123. The signal processor 130 measures the admittance of the stratum corneum of the measurement site by using the current measured by the M electrode 123.

On the other hand, since the reaction current finally measured by the moisture measuring unit 100 is merely electrical information, it should be converted into information that can indicate actual skin hydration, and the state determination included in the controller 300. The unit 310 processes this.

In the state determination unit 310, the actual physiological structure of the skin is electrically modeled and implemented. Representative modeling methods widely used include Cole-Cole's model and Yamamoto-Yamamoto's model. Substituting the reaction current measured by the moisture measuring unit 100 in the above-described model can obtain an admittance component due to the polarization phenomenon of the measurement site stratum corneum, conductance (conductance) reflecting the influence of the stratum corneum of the admittance component ) And finally remove the subsentence component, which is the AC component representing the actual stratum corneum moisture content.

In this way, after determining the moisturizing state of the skin in the state determination unit 310 of the control unit 300 to inform the user about the information on the display unit 400.

The display unit 400 uses a general electrical display device such as a liquid crystal display (LCD) or a light emitting diode (LED). The display unit 400 may be used to display the user's skin condition with a variety of information as a letter, and the skin is dried by using three color LEDs, such as red, yellow, and blue, respectively. If it is good, it can be treated simply by displaying red, and yellow when more attention is given to the moisturizing condition, and blue when moisturizing is sufficient due to sufficient moisture supply.

On the other hand, the spray unit 200 as a device for effectively spraying the aqueous solution to the skin may be a method of spraying after the aqueous solution is made of steam, but in the case of implementing a portable device, the size of the device or battery capacity, etc. Considering this, the method is difficult to adopt, but is easily adopted in other types of devices.

Therefore, in the present embodiment, a method of atomizing an aqueous solution using ultrasonic vibration is proposed. Referring to FIG. 3 (b), the spray unit 200 generates a vibration current generating unit generating an alternating current having a specific frequency. And a mist generating unit 220 for atomizing the supplied aqueous solution by ultrasonically vibrating the vibrator using the alternating current generated by the vibration current generating unit 210 and the aqueous solution generated from the mist generating unit 220. It is configured to include a discharge unit 230 for spraying the mist to the outside through the nozzle.

Ultrasonic vibration of the vibrator of the mist generating unit 220 by using the alternating current generated by the vibration current generating unit 210 to generate an ultrasonic wave having a frequency of about 1 ~ 2.5MHz. As the vibrator of the mist generator 220 vibrates ultrasonically, the vibrator also vibrates in the aqueous solution supplied to the mist generator 220, thereby changing the aqueous solution into an atomized aqueous mist by cavitation. .

The aqueous solution mist generated in this manner may be provided with a separate blower fan to be discharged to the outside through the discharge unit 230 more easily.

In addition, to provide a separate aqueous solution storage container 12 to the inside of the device to supply the aqueous solution to the spray unit 200, when the stored aqueous solution is consumed so that the aqueous solution storage container 12 can be replaced It would be desirable to configure, if it is possible to implement an integral one that can not be replaced, it should be configured a separate inlet and stopper to inject the aqueous solution into the aqueous solution storage container (12). Of course, it is also possible to implement so that the aqueous solution container 12 is not provided inside the device to be connected to the supply pipe and put to the outside.

And the aqueous solution to be stored in the aqueous solution storage container 12 may be used general water, it is preferable to use a lotion containing various active ingredients in order to help moisturizing and nutrition of the skin more.

On the other hand, when supplying the aqueous solution from the aqueous solution storage container 12 to the spray unit 200 may be to supply a uniform amount, but to adjust the injection amount to supply the optimum moisture in accordance with the user's moisturizing state It is preferable to construct.

That is, when the state determination unit 310 of the control unit 300 determines the moisturizing state of the skin of the measurer and transmits the information to the injection amount control unit 360 of the control unit 300, the injection amount control unit ( 360 is to control the amount of the aqueous solution sprayed from the spray unit 200.

In detail, the state determination unit 310 of the controller 300 classifies and programmed the moisturizing state according to the degree of skin hydration in advance, and when the numerical value measured by the moisture measurement unit 100 is transmitted, the skin is hydrated. After confirming the degree to automatically specify the moisturizing step accordingly.

In addition, the moisturizing step information specified by the state determining unit 310 is transmitted to the injection amount adjusting unit 360 so that an aqueous solution supply amount suitable for the step is transmitted to the spraying unit 200. In this embodiment, the spraying unit ( It is implemented to control the variable valve in the injection amount control unit 360 by having a variable valve in the supply pipe connecting the 200 and the aqueous solution storage container (12). Of course, in addition to any configuration that can control the amount sprayed from the spray device may be adopted.

On the other hand, even if the skin is sufficiently supplied with moisture, if time passes, the skin is dried again under the influence of natural evaporation or the surrounding environment. Therefore, it is necessary to continuously supply moisture at regular time intervals. For this purpose, the apparatus is provided with a device for counting down a certain time.

In other words, immediately after spraying the aqueous solution mist on the user's skin by operating the sprayer 200, the timer unit 330 of the control unit 300 starts counting down, and when the countdown is completed, the control unit ( The check unit 340 of 300 may exhibit that it is time to supply moisture by using the spray unit 200 again through the display unit 400. An alarm unit 350 may be further provided to visually notify the user through the display unit 400 and also play an audio or beep sound to inform the user.

In this case, the time interval for resupply moisture may be configured to be selected by the user arbitrarily, but it is preferable to set the optimized time interval in advance according to the skin condition of the user to maintain the best skin condition.

To this end, the state determination unit 310 of the control unit 300 determines the degree of skin hydration and automatically transmits the designated moisturizing step information to the analysis unit 320 of the control unit 300, and the user at the analysis unit 320. The information on the moisturizing stage of the skin determines the optimal time interval.

The time interval determined by the analysis unit 320 informs the user through the display unit 400 so as to know whether it is good to supply water again after some time passes, and the spray unit 200 After use, the timer unit 330 starts counting down.

If the user's skin is checked using the moisture measuring unit 100 and analyzed by the state determination unit 310 of the control unit 300, even if it is not necessary to supply water at the moment, the skin is checked again to check the moisturizing state. It is a good idea to count down certain time intervals for analysis.

4 is a block diagram of a control unit according to an embodiment of the present invention.

Referring to FIG. 4, the operation of a mist device having a skin condition measuring function according to an embodiment of the present invention will be described with reference to FIG. 4.

First, the user contacts the moisture measuring unit 100 with the skin and then presses an operation button to check the condition of the skin.

The information detected by the moisture measuring unit 100 is transferred to the state determining unit 310 of the control unit 300 to calculate the degree of hydration of the user's skin and determine the moisturizing step corresponding to the result. Inform the user through the unit 400.

When it is determined that the state of moisturizing of the skin is in a good stage, the state determining unit 310 transmits the information to the analyzing unit 320 and analyzes how much time is to be remeasured. It is not necessary to supply the but after the time determined by the analysis unit 320 to inform the display unit 400 that it is necessary to measure the skin condition and to start the countdown in the timer unit 330 .

When it is determined that the state of moisturizing of the skin is in a poor stage by the state determining unit 310, information about the skin moisturizing stage of the user is transmitted to the injection amount adjusting unit 360 and the analyzing unit 320, respectively. Through the spray unit 200, the amount of the aqueous mist is sprayed on the skin, and after a certain time, the skin condition is measured again and it is determined whether to supply the moisture again. Of course, the user is informed of the time interval determined through the display unit 400.

When the timer 330 completes the countdown, the checker 340 informs the user of the skin condition and supplies water through the display unit 400, and informs the user that it is time to supply moisture. The alarm unit 350 ) To play a specific sound more clearly to the user.

After that, the user repeatedly measures the skin condition using the moisture measuring unit 100 and re-supplys water if necessary.

In this way, even if the user does not particularly care to periodically supply the best moisture to the skin at the optimum time to help the user's skin is always healthy.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. In addition, it is obvious that any person having ordinary skill in the art to which the present invention pertains can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
