Background technique

The measurement and quantitative analysis of human skin oil secretion is an important part of human health measurement and human body beauty. By detecting the secretion of oil from the skin, the type of skin is determined, and what kind of cosmetics are suitable. There are two main methods for measuring the secretion of oil from the skin:

First, through artificial rough detection, such as paper towel wiping method, take a piece of soft tissue paper or blotting paper, wipe repeatedly on both sides of the nose or forehead, and wipe off the sebum secreted from the skin as much as possible. If the paper towel is full of shine, it indicates that the secretory function of the skin gland is relatively strong and belongs to oily skin; if the color of the paper towel is not light, it is dry skin; between the two, it belongs to neutral skin; Different parts of the oil content is mixed skin. Or the face-washing method, using the skin tightness after washing the face, observing the disappearance of the tightness without any cosmetic conditions, the oily skin disappeared within 20 minutes, and the neutral skin disappeared within 30 minutes. Those who disappeared in 40 minutes belong to dry skin.

Second, the machine detection method, which is based on the principle of photometer, uses organic materials such as special matting tape to absorb the oil on human skin, and accurately measures according to the change of the light transmittance of the organic material.

detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIG. 1 , a skin oil transfer probe 10 is provided in an embodiment of the present invention. The transfer probe 10 is made of a hydrophobic acrylate. The transfer probe 10 has a plate-like structure having a thickness, and the plate-like structure The two end faces are parallel to each other, and the orthographic projections of the both end faces have overlapping portions. The transfer probe of the utility model can fully utilize the oil-absorbing and hydrophobic property of the hydrophobic acrylate to complete the process of grease transfer. After the transfer probe 10 transfers the grease, the moisture will quickly evaporate due to its lipophilic and hydrophobic properties, and the grease is It will infiltrate, thus affecting the transparency of its surface. The more oil, the better the light transmittance, and the smaller the light reflectivity, the utility model can be repeatedly used by the organic cleaning agent for cleaning, greatly improving the use of the transfer probe 10. Life expectancy and reduce waste of resources.

The side surface of the transfer probe 10 described in this embodiment can be painted black to prevent the side surface of the transfer probe 10 from reflecting light to affect the purity of transmitted light or reflected light, and to improve the accuracy of subsequent grease detection. The skin oil transfer transfer probe 10 of the present invention generally has a plate-like structure in which both end faces of the thickness are parallel to each other and have a front projection overlapping portion therebetween, and the two end faces are generally the same shape, and may be circular or square. , rectangular, and other shapes such as animals. In a specific embodiment, the plate-shaped transfer probe 10 is a circular table having a front surface that is in contact with the human body having a diameter of 3-5 mm, a back surface having a diameter of 6-8 mm, and a thickness of more than 1-10 mm. The design can fully contact the human skin, while the back is slightly larger than the front, making it easy to install other components, such as light source, light intensity sensor, etc. Of course, the cylinder can also be He can also achieve it. Regarding the choice of thickness, it is possible to thicken in principle, but in order to facilitate the collection of light or reflected light after transfer of grease, especially for the collection of reflected light, a certain design is required, such as a front diameter of 5 mm and a back surface. The 8 mm circular table-shaped transfer probe 10 is generally selected to have a thickness of 6-7 mm. Because the thickness is different, when the same beam of light illuminates the transfer probe, the light-emitting position of the transmitted light and the light reflected by the front side are different at the light-emitting position of the back surface, which will have a certain influence on the position of the light-intensity sensor that collects the light, and When the thickness of the printing probe 10 is appropriately selected, the position of the light intensity sensor or the like can be better set.

In the embodiment of the skin oil transfer probe 10 of the present invention, the front surface 11 of the transfer probe 10 in contact with the skin is a frosted surface, that is, matte treatment is performed on the front surface of the transfer probe 10, and the frosted surface is convenient. The transfer and adsorption of grease will also diffuse the light beam, which is convenient for the light intensity sensor 30 to collect the light intensity of the uniform reflected light, so that the subsequent detection of oil secretion is more accurate.

Referring to FIG. 2, an embodiment of the present invention further provides a method for measuring skin oil secretion, comprising the steps of:

S1, in a dark environment, the beam emitter 20 emits a light beam to illuminate the back surface 12 of the transfer probe 10, wherein the transfer probe 10 is made of a hydrophobic acrylate, and the transfer probe 10 is formed into a plate-like structure having a thickness. The end faces of the structure are parallel to each other, and the orthographic projections of the both end faces have overlapping portions. In the transfer probe of the present invention, the emitting end of the beam emitter 20 and the back surface 12 of the transfer probe 10 have a seamless contact with the frontal projection of the front side, and the receiving end of the light intensity sensor and the back side of the transfer probe 10 have The portion of the front orthographic projection coincides with the seamless contact, and the reflection of the light can be better received. Of course, in other embodiments, the receiving end of the light intensity sensor 30 and the back surface of the transfer probe 10 do not coincide with the front projection of the front side. Seamless contact, because diffuse reflection occurs on the front side of the transfer probe 10, and some of the diffused light is collected by the light intensity sensor 30; the back surface 12 of the transfer probe 10 is in seamless contact with the beam emitter 20, resulting in a beam The light emitted by the emitter 20 directly passes through the back surface 12 of the transfer probe 10 without the reflected light generated by the back surface 12 of the transfer probe 10 overflowing, and the source of the light collected by the light intensity sensor 30 is more singular, It can be ensured that in the subsequent step, the light intensity sensor 30 only receives the light reflected by the front surface 11 of the transfer probe 10, and the back side of the transfer probe 10 is in seamless contact with the receiving end of the light intensity sensor 30 for better Receiving the reflected light, the reflected light is too weak to prevent undetected; in the dark environment, to prevent interference with the natural light detection result.

S2, part of the light emitted by the beam emitter 20 is reflected by the front surface 11 of the transfer probe 10, and the light intensity sensor 30 takes The intensity of the reflected light is collected; the light intensity sensor 30 includes a photosensitive element and a control circuit, and the control circuit includes a signal acquisition circuit, a signal amplification circuit, a signal conversion filter, and the like, and of course, an analog-to-digital conversion circuit, etc., and the photosensitive element is based on the light intensity. Differently send different electrical signals to the control circuit.

S3. Analyze the skin oil secretion according to the light intensity change collected by the light intensity sensor 30. The smaller the light intensity of the light collected by the light intensity sensor 30, the greater the light transmittance of the transfer probe 10, and the more secretion of oil, because After transferring the grease to the transfer probe 10, due to its lipophilic and hydrophobic properties, the moisture will evaporate rapidly, and the oil will infiltrate, thereby affecting the transmittance of the surface. The more oil, the better the light transmittance and the lower the light reflectance. The amount of grease on the transfer probe is analyzed according to the change in the reflectance. The more the reflected light, the less the grease, and the less the reflected light, the more the grease. In a specific embodiment, the oil secretion level is preset, and the range of the light intensity level corresponding to the oil secretion level is set, for example, the oil secretion level of the oily skin is 2, and the corresponding light intensity range is 100-200 lx. When the light intensity sensor collects the light before the temperature is 150lx, the corresponding oil secretion amount is level 2, and when the detection person detects, the light intensity is inversely proportional to the amount of oil secretion, when the transfer probe 10 is transferred. If the grease is large, the light transmissive area on the transfer probe 10 is large, so most of the light emitted by the beam emitter 20 is directly transmitted through the transfer probe 10, and the reflected light is less, and the light intensity sensor 30 collects the light. The light intensity will be lower, and the result of the analysis is to detect more oil on the human skin.

The side surface of the transfer probe 10 described in this embodiment is painted black, preventing the side surface of the transfer probe 10 from reflecting light to affect the purity of transmitted light or reflected light, and improving the accuracy of subsequent grease detection. The skin oil transfer transfer probe 10 of the present invention generally has a plate-like structure in which both end faces of the thickness are parallel to each other and have a front projection overlapping portion therebetween, and the two end faces are generally the same shape, and may be circular or square. , rectangular, and other shapes such as animals. In a specific embodiment, the plate-shaped transfer probe 10 is a circular table having a front surface that is in contact with the human body having a diameter of 3-5 mm, a back surface having a diameter of 6-8 mm, and a thickness of more than 1-10 mm. The design can fully contact the human skin, while the back side is slightly larger than the front side, which is convenient for installing other components, such as light source, light intensity sensor, etc. Of course, the cylinder can also be realized. Regarding the choice of thickness, it is possible to thicken in principle, but in order to facilitate the collection of light or reflected light after transfer of grease, especially for the collection of reflected light, a certain design is required, such as a front diameter of 5 mm and a back surface. The 8 mm circular table-shaped transfer probe 10 is generally selected to have a thickness of 6-7 mm. Because of the different thicknesses, when the same beam of light illuminates the transfer probe, the light-emitting position of the transmitted light, and The light reflected on the front side has different light-emitting positions on the back surface, which will have a certain influence on the position of the light intensity sensor for collecting light. When the thickness of the printing probe 10 is properly selected, the position of the light intensity sensor can be better set. In an embodiment of the method for measuring skin oil secretion according to the present invention, the front surface 11 of the transfer probe 10 is a frosted surface, and the frosted surface can facilitate the transfer and adsorption of grease, and diffusely reflect the light beam to facilitate the light intensity sensor 30. The light intensity of the uniform reflected light is collected, so that the subsequent detection of oil secretion is more accurate.

In an embodiment of the skin oil secretion measuring method of the present invention, the step S1 of the beam emitter 20 emitting the light beam to illuminate the back surface 12 of the transfer probe 10 includes: step S11, the transfer probe 10 is in contact with the skin, wherein the transfer is performed. The pressure value generated by the probe 10 in contact with the skin is a pressure value within a specified range, and the pressure value is a pressure value within a specified range to determine the transfer condition of the transfer grease, thereby improving the accuracy of the measurement, such as using the same face on the human face. The transfer probe 10 is pressed at the same position, and the amount of transfer grease is different due to the difference in applied pressure. The amount of grease applied with a small applied pressure is smaller than the amount of grease transferred with a large applied pressure, and the final measurement result is It will be different, so specifying a pressure value within a specified range is equivalent to proposing a standard within which a relatively accurate measurement result is easily obtained.

In an embodiment of the method for measuring skin oil secretion according to the present invention, the step S11 of contacting the transfer probe 10 with the skin includes: the time when the pressure value generated by the transfer probe 10 in contact with the skin is within the specified range is a specified time. . That is to say, the condition of the transfer probe 10 in contact with the skin is further limited, and the contact of the transfer probe 10 with the skin is completed within a prescribed time range within a prescribed time, because the time when the transfer probe 10 is in contact with the skin is also The amount of transfer grease can be changed. For example, the longer the transfer probe 10 is in contact with the skin, the more grease will be transferred, so the transfer probe 10 and the skin have standard pressure and time, and the later grease analysis The measurement will be more accurate.

In an embodiment of the method for measuring skin oil secretion according to the present invention, the step S2 of the beam emitter 20 emitting a light beam to illuminate the back surface 12 of the transfer probe 10 includes: waiting for evaporation of moisture on the transfer probe 10 because of the transfer When the oil on the skin is transferred to the transfer probe 10 at the same time, although there are not many water molecules, it will also affect the reflection of light, resulting in inaccurate final measurement results while waiting for transfer. The evaporation of the water on the probe 10 will solve this problem, and the waiting time will not be long, because there are not many water molecules, and the specific waiting time will depend on the size of the transfer probe 10, the transfer time, the transfer strength, etc. Make corresponding settings, such as touching an oily skin to the maximum value within the force range, After that, the time at which the water molecules on the transfer probe 10 evaporate is detected, and then the time is set as the shortest waiting time and the like.

The above method for measuring the secretion of skin oil fully utilizes the oil-absorbing hydrophobic property of the hydrophobic acrylate to complete the process of grease transfer, and can be repeatedly used by the organic cleaning agent for cleaning, greatly improving the service life of the transfer probe 10 and reducing resources. Waste; a measure of skin oil secretion, which is in seamless contact with the beam emitter 20 through the back side 12 of the transfer probe 10, causing light emitted by the beam emitter 20 to pass directly through the back side 12 of the transfer probe 10 without a transfer probe The reflected light generated by the back surface 12 of the 10 overflows, and the light emitted from the light beam emitter 20 is irradiated on the front surface 11 of the transfer probe 10 and reflected, and the light intensity sensor 30 receives only the emitted light of the front surface 11 of the transfer probe 10, thereby making it The skin oil secretion can be accurately reflected, and the pressure, time, and the like of the transfer probe 10 in contact with the skin can be further set to improve the accuracy of the final measurement result.

Referring to FIG. 3, an embodiment of the present invention further provides a skin oil secretion measuring device, which comprises a transfer probe 10 made of a hydrophobic acrylate, a beam emitter 20 and a light intensity sensor 30. The transfer probe 10 has a thickness. a plate-like structure in which both end faces of the plate-like structure are parallel to each other, and the orthographic projections of the both end faces have overlapping portions, and the beam emitter 20 and the light intensity sensor 30 are disposed on the back side of the transfer probe 10, Both the transmitting end of the beam emitter 20 and the receiving end of the light intensity sensor 30 are in seamless contact with the back surface 12 of the transfer probe 10. In the present embodiment, the emitting end of the beam emitter 20 and the back side 12 of the transfer probe 10 have The part that coincides with the frontal orthographic projection is in seamless contact, and the receiving end of the light intensity sensor and the back side of the transfer probe 10 have seamless contact with the frontal projection of the front side of the transfer probe 10, so that the reflection of light can be better received, of course, in other In the embodiment, the receiving end of the light intensity sensor 30 is in seamless contact with the portion of the back surface of the transfer probe 10 that is not coincident with the front side of the transfer probe 10, because the front side of the transfer probe 10 is diffusely reflected, diffusely reflected light Some of the light is transmitted by the light intensity sensor 30; the light beam emitter 20 emits a light beam which is irradiated on the front surface 11 of the transfer probe 10 through the back surface 12 of the transfer probe 10 to generate reflected light, and the light intensity sensor 30 collects the reflected light. The light intensity of light. The beam emitter 20 and the light intensity sensor 30 are disposed on the same side of the transfer probe 10, and the beam emitter 20 and the light intensity sensor 30 of the prior art skin oil secretion measuring device are respectively disposed with the transfer probe 10 On the side, the volume is obviously smaller, the product is more compact, and it is easy to use and carry. The material of the transfer probe 10 is hydrophobic acrylate, which fully utilizes the oil-absorbing and hydrophobic characteristics of the hydrophobic acrylate to complete the process of grease transfer. After the probe 10 transfers the grease, it is hydrophobic due to its lipophilicity. The characteristic is that the water will evaporate quickly, the oil will infiltrate, thus affecting the transparency of the surface. The more oil, the better the light transmittance, and the smaller the light reflectivity, the analysis of the transfer probe according to the change of the light reflectance. The amount of grease, the more light is reflected, the less oil, the less reflected light, the more grease; the transfer probe 10 can be repeatedly cleaned by organic cleaning agent, greatly improving the service life of the transfer probe 10, reducing Waste of resources. The back side 12 of the transfer probe 10 is in seamless contact with the beam emitter 20, causing the light emitted by the beam emitter 20 to pass directly through the back side 12 of the transfer probe 10 without the reflected light from the back side 12 of the transfer probe 10 overflowing. The source of the light collected by the light intensity sensor 30 is singularly strong, and it can be ensured that in the subsequent step, the light intensity sensor 30 only receives the light reflected by the front surface 11 of the transfer probe 10, and the back surface of the transfer probe 10 and the light intensity The receiving end of the sensor 30 is in seamless contact in order to better receive the reflected light and prevent the reflected light from being too weak to be detected.

The side surface of the transfer probe 10 described in this embodiment is painted black, preventing the side surface of the transfer probe 10 from reflecting light to affect the purity of transmitted light or reflected light, and improving the accuracy of subsequent grease detection. The skin oil transfer transfer probe 10 of the present invention generally has a plate-like structure in which both end faces of the thickness are parallel to each other and have a front projection overlapping portion therebetween, and the two end faces are generally the same shape, and may be circular or square. , rectangular, and other shapes such as animals. In a specific embodiment, the plate-shaped transfer probe 10 is a circular table having a front surface that is in contact with the human body having a diameter of 3-5 mm, a back surface having a diameter of 6-8 mm, and a thickness of more than 1-10 mm. The design can fully contact the human skin, while the back side is slightly larger than the front side, which is convenient for installing other components, such as light source, light intensity sensor, etc. Of course, the cylinder can also be realized. Regarding the choice of thickness, it is possible to thicken in principle, but in order to facilitate the collection of light or reflected light after transfer of grease, especially for the collection of reflected light, a certain design is required, such as a front diameter of 5 mm and a back surface. The 8 mm circular table-shaped transfer probe 10 is generally selected to have a thickness of 6-7 mm. Because the thickness is different, when the same beam of light illuminates the transfer probe, the light-emitting position of the transmitted light and the light reflected by the front side are different at the light-emitting position of the back surface, which will have a certain influence on the position of the light-intensity sensor that collects the light, and When the thickness of the printing probe 10 is appropriately selected, the position of the light intensity sensor or the like can be better set.

In an embodiment of the skin oil secretion measuring device of the present invention, further comprising a force sensor 40, the force sensor 40 is in contact with the tail end of the beam emitter 20 for detecting the pressure of the transfer probe 10 in contact with the skin, such that When the transfer probe 10 is pressed against the skin, the pressure received by the transfer probe 10 passes through the light beam. The transmitter 20 is transmitted to the force sensor 40 such that the force sensor 40 collects the pressure value of the transfer probe 10 in contact with the skin so that the user can clearly know what the pressure value of the transfer probe 10 in contact with the skin is. Further, the skin oil secretion measuring device is further provided with an indicator light 90 associated with the force sensor 40, and the indicator light 90 displays different colors according to the force change collected by the force sensor 40, and the setting of the indicator light 90 can be clearly Intuitively knowing the magnitude of the pressure, such as when the pressure is less than a certain set value, it is yellow, when it is larger than when it is green, etc., in the embodiment, when the skin oil secretion measuring device transfers skin oil, the transfer probe 10 is The pressure value generated by skin contact is the pressure value within the specified range. The pressure value is the pressure value within the specified range to determine the transfer condition of the transfer grease, and the measurement accuracy is improved, such as using the same transfer probe on the human face. 10 Pressing the same position, the amount of transfer grease will be different due to the difference in applied pressure. The amount of grease transferred with a small applied pressure is smaller than the amount of grease transferred with a large applied pressure, and the final measurement result will be different. Therefore, specifying a pressure value within a specified range is equivalent to proposing a standard within which a relatively accurate measurement is easily obtained. However, at this time, the change of the indicator light 90 can be correspondingly changed. If the indicator light 90 is less than the specified pressure range, the indicator light 90 is yellow. When the pressure range is within the specified pressure range, the indicator light 90 turns green, which is greater than the specified pressure range. The indicator light 90 turns red and an alarm device can also be set. In this embodiment, the indicator light 90 may be one turn or multiple turns. When there are multiple turns, the different indicator lights 90 may be turned on according to the pressure of the force sensor 40.

In an embodiment of the skin oil secretion measuring device of the present invention, the skin oil secretion measuring device is further provided with a timer 70 associated with the force sensor 40 for detecting a pressure value generated by the transfer probe 10 in contact with the skin in a specified range. Time inside. When the force collected by the force sensor 40 reaches the specified range, the timer 70 is turned on, and the timer 70 sends an alarm signal after the specified time to remind the user to stop detecting the contact of the transfer probe 10 with the skin, which can effectively improve the skin. The grease detection is accurate, because the time when the transfer probe 10 is in contact with the skin can also change the amount of transfer grease. For example, the longer the transfer probe 10 is in contact with the skin, the more grease will be transferred, so the transfer probe 10 and When the skin is standard in terms of pressure and time, the later analysis of the grease will be more accurate. The timer 70 can also time the time when the transfer probe 10 is separated from the skin. When the transfer probe 10 is separated from the skin for a specified time, the emitted light beam will emit light, because the skin will be simultaneously transferred when transferring grease on the skin. The water molecules on the transfer are transferred to the transfer probe 10 together. Although there are not many water molecules, they also affect the reflection of the light, resulting in the final measurement junction. If the result is inaccurate, and waiting for the evaporation of the water on the transfer probe 10, the problem will be solved, and the waiting time will not be long, because there are not many water molecules, and the specific waiting time will be according to the size of the transfer probe 10, Transfer time, transfer strength, etc. are set correspondingly, such as touching an oily skin to the maximum value within the force range, and then detecting the time when the water molecules on the transfer probe 10 evaporate, and then setting the time to the shortest Waiting time, etc.

In an embodiment of the skin oil secretion measuring device of the present invention, the front surface 11 of the transfer probe 10 is a frosted surface. The frosted surface can not only facilitate the transfer and adsorption of grease, but also diffusely reflect the light beam, which is convenient for the light intensity sensor 30 to collect the light intensity of the uniform reflected light, so that the subsequent detection of oil secretion is more accurate.

The light intensity collected by the light intensity sensor 30 in the skin oil secretion measuring device is sent to the analyzer 200, and the analyzer 200 obtains the skin oil secretion according to the light intensity analysis. Usually, the light intensity sensor 30 is connected to the analyzer via the controller 50. The analyzer 200 can be disposed in the same housing as the skin oil secretion measuring device, that is, the controller 50 is also the analyzer 200, and can also be designed separately. The analyzer 200 is a single chip microcomputer or a smart terminal.

For example, if the analysis software is installed in the smart phone, when the skin oil is detected, the measuring device can be directly secreted with the skin oil through the smart phone, which is convenient and improved. The user experience can also reduce hardware costs. In the present invention, the oil secretion level is preset in the analyzer 200, and the range of the light intensity level corresponding to the oil secretion level is set, for example, the oil secretion level of the oily skin is 2, and the corresponding light intensity range is 100-200 lx. When the light intensity of the light intensity sensor is 150lx, the corresponding oil secretion amount is 2, and when the detection is detected, the light intensity is inversely proportional to the amount of oil secretion, when the transfer probe 10 is rotated. Since the printed grease has a large amount of light, the light transmission area on the transfer probe 10 is large, so most of the light emitted by the light beam emitter 20 is directly transmitted through the transfer probe 10, and the reflected light is less. At this time, the light intensity sensor 30 collects. The light intensity will be lower, and the result of the analysis is to detect more oil on the human skin.

The sensor 30 also provides uniform emission of light to the intensity sensor 30.

In each of the above embodiments, the material of the transfer probe 10 is a hydrophobic acrylate, which can fully utilize the oil-absorbing and hydrophobic characteristics of the hydrophobic acrylate to complete the process of transferring the grease, and can be repeatedly used by the organic cleaning agent for cleaning. The service life of the transfer probe 10 is improved, the waste of resources is reduced, and the design of the frosted surface can improve the uniformity of the reflected light; the method for measuring the secretion of skin oil is seamlessly contacted with the beam emitter 20 through the back surface 12 of the transfer probe 10, resulting in The light emitted from the beam emitter 20 directly passes through the back surface 12 of the transfer probe 10 without the reflected light generated by the back surface 12 of the transfer probe 10 overflowing, and the light emitted from the beam emitter 20 is irradiated on the front side of the transfer probe 10. 11 and performing reflection, the light intensity sensor 30 receives only the emitted light of the front surface 11 of the transfer probe 10, so that it can accurately reflect the secretion of skin oil, and the skin oil secretion measuring device according to the method, the light beam The emitter 20 and the light intensity sensor 30 are disposed on the back side of the transfer probe 10, which can reduce the volume of the device, making it convenient to carry and use.
