Description

Technical Field

[0001] The present invention relates to the field of skin moisture detection, and in particular to a skin moisture detection device and method. Background Art

[0002] As people's living standards improve, they will pay more attention to their physical condition, such as the condition of their skin. The better the skin's hydration, the more moisturized and smooth the skin is. Existing skin moisture meters generally use dual-electrode impedance detection to perform single-point multiple detections to determine one's own skin moisture condition. However, the existing skin moisture meters have a simple structure and are only tested by contacting the skin with dual electrodes. The skin moisture meters are prone to movement, which causes the skin moisture meter to re-detect the skin moisture after movement. The front and back detection data will interfere with each other, affecting the final skin moisture detection results. In addition, single-point multiple detections result in a small amount of measured data, and the detection results are not representative and can only be used as a simple reference.

[0028] A skin moisture detection method comprises the following steps: S1, holding the handle 1, sliding the scraper 15 downward, and then making the scraper 15 contact the skin to be tested for moisture, and scraping to remove the stains of residual moisture on the skin, and then returning the scraper 15 to the initial position after cleaning; S2, then put the contact piece 7 on the skin, and gently squeeze the contact piece 7 to squeeze out the air in the contact piece 7, and fix the contact piece 7 on the skin to ensure that the device does not move during the skin moisture detection process; S3, control the switch key 2 to turn on, so that the multiple probes 11 synchronously detect the moisture of the skin, the amount of data is large, and multiple skin moisture data are obtained, which are automatically summarized and analyzed to obtain more representative skin moisture data; S4. When the probe 11 is retracted, the probe 11 is automatically cleaned to ensure the accuracy of the next detection result.

[0029] The working steps of the above embodiment are: The skin moisture detection device is portable and handheld. The user directly holds the handle 1, first pushes the scraper 15 downward, and then makes the scraper 15 contact with the skin and scrapes on the skin, thereby scraping off the residual moisture and stains on the skin surface, and then cleans the arc-shaped scraping strip at the bottom of the scraper 15, and then makes the scraper 15 move upward and reset, and then turns on the device by pushing the switch key 2 until the display screen 3 lights up, and then the user points one side of the detection head 6 toward the position where the skin moisture is to be checked, and presses the conical contact piece 7 on the skin, and then controls the start electric actuator 8 to contract, synchronously driving the concentric frame 9 and the corresponding parts thereon to move downward, and the eight probes 11 are all extended from the bottom of the detection head 6 until the eight probes 11 are all pressed on the skin. Considering the position where the user detects the skin moisture, the skin surface is not complete, and the eight probes 11 are synchronously descended, so by setting an elastic member Ⅰ10 on the probe 11, the probe 1 that first contacts the skin 1, the corresponding elastic member Ⅰ10 on the handle 1 is compressed, and the other probes 11 continue to descend until all the probes 11 are in contact with the user's skin. At this time, the contact member 7 effectively isolates the external environment, and the eight probes 11 begin to synchronously detect the moisture of the skin. The detection time is 5-10S, and then the electric actuator 8 is controlled to extend, and the concentric frame 9 and the corresponding parts thereon are synchronously driven to reset. Then, after the detection results of the eight probes 11 are summarized and analyzed, the final skin moisture value is obtained and displayed on the display screen 3. When the buzzer set on the handle 1 sounds, the user puts the moisture detection device flat for the user to view the moisture data, so as to obtain a more accurate value of the user's skin moisture through a single multi-point skin moisture detection. Compared with the prior art, by measuring the skin moisture of a single point multiple times, not only time is wasted, but also the force of pressing the skin moisture meter each time cannot be accurately unified, so that the final skin moisture detection results obtained vary greatly.

[0030] It is taken into consideration that when the probe 11 is pressed against the user's skin for moisture detection, the movement of the user's hand causes the position of the probe 11 to move, and then causes the probe 11 to re-detect the moisture at the moved position, which not only wastes time but also causes the detection results to interfere with each other. At this time, the contact member 7 is set to a silicone cover made of skin-friendly material. When the user presses the contact member 7 against the skin, the contact member 7 begins to deform, and the air in the contact member 7 is squeezed into the detection head 6, and then the air impacts the pore I6002 and pushes the sealing sheet 14 open. At this time, the sealing sheet 14 does not completely block the pore I6002, and the corresponding elastic member II13 is compressed, and the excess air in the detection head 6 is discharged from the pore I6002. After the contact member 7 stops deforming, the elastic member II13 recovers, and synchronously causes the sealing sheet 14 to re-block the pore I6002. At this time, the contact member 7 is under negative pressure, and the contact member 7 is adsorbed on the user's skin, so that the detection position will not move easily, thereby obtaining the final accurate skin moisture data for easy use.

[0031] After the waiting time for skin moisture detection, a buzzer is provided on the handle 1, and the buzzer prompts the user to gently pull the moisture detection device to separate the contact member 7 from the user's skin. Then the user can check the skin moisture data on the display screen 3 to decide the next skin moisture maintenance plan. Considering that the probe 11 needs to be in contact with the skin when detecting the moisture of the skin, and the grease, dust and sweat stains carried on the surface of the skin are transferred to the probe 11 when contacting the probe 11, affecting the subsequent detection accuracy of the probe 11. Therefore, before the lower part of the probe 11 completely enters the detection head 6, the display screen 3 displays the moisture result and controls the start of the motor 101 at the same time. The output shaft of the motor 101 drives the gear 102 to drive the gear ring 103 to rotate, and the gear ring 1 03 drives all the outer toothed rings 104 to rotate, and the bristles on the outer toothed rings 104 begin to rotate and clean the lower part of the probe 11 to prevent grease, dust and sweat from adhering to the probe 11. The bristles of the outer toothed rings 104 are set to be inclined toward the side away from the concentric frame 9, so that when the probe 11 is retracted to the detection head 6, the bristles of the outer toothed rings 104 are fully in contact with the lower part of the probe 11, and the stubborn residual dirt in the lower part of the probe 11 is cleaned to ensure the accuracy of the detection result. After the lower part of the probe 11 is cleaned, the probe 11 is reset and the motor 101 is controlled to be turned off, which is fed back to the display screen 3, indicating that the self-cleaning is completed and the display screen 3 is turned off. Finally, use this to gently push the switch key 2 to turn off the skin moisture detection device, and then put the skin moisture detection device properly.

[0032] In order to meet the user's requirement for portability, not only is a charging connector 4 provided, so that the skin moisture detection device can be extended by direct charging, but on this basis, a battery compartment 5 can be added so that the rechargeable battery can be replaced. When the user is traveling long distances and there is no charging interface, the spare battery can be loaded into the battery compartment 5 to achieve extended battery life and solve the user's anxiety about power consumption, which greatly meets the use needs.

[0033] Second embodiment On the basis of the first embodiment, according to Figure 1-Figure 3 and Figure 7-Figure 8 As shown, it also includes a protective cover 201; each probe 11 is fixedly connected to a protective cover 201; the protective cover 201 is made of silicone; all protective covers 201 are fixedly connected to the detection head 6; each protective cover 201 is opened with a plurality of air holes II 20101.

[0034] The working steps of the above embodiment are: On the basis of the first embodiment, it is also necessary to consider that when the skin moisture detection device is not in use, the detection head 6 is directly connected to the outside air, and the outside air can easily enter the detection head 6. The blocking effect of the bristles of the outer toothed ring 104 can filter the incoming air to a certain extent, but dust and impurities still enter the detection head 6 with the air, resulting in dust accumulation in the detection head 6, which is troublesome to clean. In addition, during the rotation of the bristles, the lower part of the probe 11 is cleaned, and some dirt adheres to the bristles of the outer toothed ring 104. During the rotation of the bristles of the outer toothed ring 104, dirt will be thrown into the detection head 6, further increasing the difficulty of cleaning the detection head 6. Therefore, a silicone protective cover 201 is arranged between the probe 11 and the lower part of the detection head 6, and the protective cover 201 is provided with an air hole II 20101. When the probe 11 is in the initial position, the probe 11 pulls the protective cover 201 to open the air hole II 20101. Figure 8 As shown in the middle left figure, when in use, the contact piece 7 is squeezed, and the air in the contact piece 7 can enter the detection head 6 through the pore II 20101, and then be discharged to the external environment through the pore I 6002. When the user's skin moisture is detected, because the contact piece 7 is sucked on the skin, and the detection process needs to last for a short period of time, the respiration of the skin will also cause moisture to evaporate, and the moisture can easily enter the detection head 6, causing the electronic components in the detection head 6 to be damp, affecting the service life of the electronic components in the detection head 6. After the protective cover 201 is added, during the process of the probe 11 detecting the skin moisture, the probe 11 does not pull the protective cover 201, and the pore II 20101 on the protective cover 201 is in a closed state. Figure 8As shown in the middle right figure, the water evaporated from the skin cannot enter the detection head 6, ensuring the service life of the electronic components in the detection head 6. After the detection is completed, the probe 11 is returned to the detection head 6, and the bristles of the outer tooth ring 104 are used to clean the probe 11. The protective cover 201 is not stretched, and the pore II 20101 is semi-closed, as shown in FIG. Figure 8 As shown in the middle right figure, the dirt on the bristles of the outer tooth ring 104 will not be thrown into the detection head 6, and even after the probe 11 is reset, the outside air needs to be filtered by the bristles of the outer tooth ring 104 before entering the detection head 6, and then pass through the pores II 20101 before entering the detection head 6. The protective cover 201 intercepts most of the ash impurities, effectively keeping the detection head 6 clean and tidy, thereby extending the service life of the moisture detection device.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
