[0024] Embodiment 1: This embodiment provides a temperature feedback-based controllable microwave beauty device, combined with Figures 1 to 4 shown.

[0025] A controllable microwave beauty device for face-mounting based on temperature feedback, the device comprises a microwave beauty instrument, an analysis module, a control module, a skin damage assessment module, a start-stop module and a communication module; the microwave beauty instrument heats the skin by microwaves; the analysis module is used to analyze and obtain relevant information about the microwave beauty instrument, skin and environment, and transmit the information to the control module; the control module obtains a skin temperature change factor based on the relevant information about the microwave beauty instrument, skin and environment, and transmits the skin temperature change factor to the skin damage assessment module; the skin damage assessment module obtains information on whether the skin is damaged based on the skin temperature change factor, and transmits the information to the start-stop module and the communication module; the start-stop module sends a stop signal to the microwave beauty instrument based on the skin damage information, and the microwave beauty instrument stops microwave output based on the stop signal; the communication module transmits the information on whether the skin is damaged to a user end.

[0026] Specifically, when the skin damage assessment module is evaluated, the following principles are referred to: when the skin temperature change factor is greater than or equal to the selection threshold of the skin temperature change factor, it indicates that the skin will be damaged; when the skin temperature change factor is less than the selection threshold of the skin temperature change factor, it indicates that the skin will not be damaged; the selection threshold of the skin temperature change factor is set by technical personnel in this field; it can be understood that: the thermal capacity of the skin is limited, and when the value of the skin temperature change factor is larger (that is, the faster the skin temperature changes), it is easy to cause thermal damage to the epidermal tissue, especially at excessively high temperatures. The skin's tolerance to heat is limited, and rapid changes in temperature may exceed the skin's self-repair ability, causing burns or other adverse reactions.

[0027] Optionally, the analysis module is used to analyze and derive the output power of the microwave beauty instrument, the specific heat of the skin, the thermal conductivity of the skin, the surface area of ​​the skin in contact with the microwave beauty instrument, the skin temperature, the ambient temperature, the skin thickness, the skin humidity, the skin blood flow, the skin density and the surface area of ​​the skin, and transmit them to the control module; the control module derives the skin weight according to the skin density, the surface area of ​​the skin and the skin thickness, and derives the skin temperature change factor according to the skin weight, the output power of the microwave beauty instrument, the specific heat of the skin, the thermal conductivity of the skin, the surface area of ​​the skin in contact with the microwave beauty instrument, the skin temperature, the ambient temperature, the skin thickness, the skin humidity and the skin blood flow.

[0028] Optionally, the analysis module includes a power detection submodule, an information storage submodule, a temperature detection submodule, a thickness detection submodule, a humidity detection submodule, a blood flow detection submodule and a surface area detection submodule; the power detection submodule is used to detect and obtain the output power of the microwave beauty instrument, and transmit it to the control module; the information storage submodule is used to store the specific heat capacity of the skin, the thermal conductivity of the skin, the surface area of ​​the skin in contact with the microwave beauty instrument and the skin density, and transmit them to the control module; the temperature detection submodule is used to detect and obtain the skin temperature and the ambient temperature, and transmit them to the control module; the thickness detection submodule is used to detect and obtain the skin thickness, and transmit it to the control module; the humidity detection submodule is used to detect and obtain the skin humidity, and transmit it to the control module; the blood flow detection submodule is used to detect and obtain the skin blood flow, and transmit it to the control module; the surface area detection submodule is used to detect and obtain the surface area of ​​the skin, and transmit it to the control module.

[0029] Specifically, when the blood flow detection submodule is detecting, refer to the following detection steps: the laser diode emits a low-power laser beam and irradiates the skin surface; part of the laser enters the skin and is scattered by static tissue and moving blood cells (red blood cells), the scattered light of the static tissue maintains the original frequency, and the movement of blood cells causes the scattered light to produce a Doppler frequency shift; the photodetector (such as a photosensitive diode) collects the scattered light signal reflected from the skin; the Doppler frequency shift information is extracted through spectral analysis of the optical signal, from which the speed and concentration of the blood cells are calculated, and the skin blood flow is obtained based on the intensity and number of the Doppler frequency shift.

[0030] Optionally, the surface area detection submodule includes an image input unit, a region segmentation unit and a calculation unit; the image input unit is used to collect skin images; the region segmentation unit segments the skin and the background through a detection algorithm, and uses edge detection to extract the contour of the skin area; the calculation unit is used to calculate and obtain the surface area of ​​the skin, and transmit it to the control module.

[0031] Optionally, when the control module calculates the skin temperature change factor, the following formula is satisfied: Where Cist is the skin temperature change factor, Q is the output power of the microwave beauty instrument, m is the skin weight, c is the specific heat capacity of the skin, k is the thermal conductivity of the skin, s is the surface area of ​​the skin in contact with the microwave beauty instrument, and temp skin is the skin temperature, temp e is the ambient temperature, hd is the skin thickness, w is the skin humidity, and v is the skin blood flow.

[0032] Optionally, when the control module calculates, the following formula is satisfied: m=md×bmj×hd; wherein md is the skin density, and bmj is the surface area of ​​the skin.

[0033] When the control module calculates the skin temperature change factor, refer to the following program code:

[0034]

[0035]

[0036]

[0037] Specifically, the unit of the output power of a microwave beauty instrument is watt; the unit of skin weight is kilogram; the unit of specific heat capacity of skin is J / kg·℃, and the value is usually 3500J / kg·℃; the greater the output power of a microwave beauty instrument, the more energy it represents, and the corresponding greater the skin temperature change.

[0038] The unit of thermal conductivity of the skin is W / m·℃, and the value is usually 0.5W / m·℃; the unit of the surface area of ​​the skin in contact with the microwave beauty device is square meter; the units of skin temperature and ambient temperature are both degrees Celsius; the greater the difference between skin temperature and ambient temperature, the faster the heat flows, and the greater the corresponding skin temperature change.

[0039] The unit of skin thickness is meter; the thicker the skin, the longer the distance heat needs to be transferred, and the corresponding skin temperature change is smaller.

[0040] Skin humidity is expressed as a percentage. A moist skin surface can absorb microwave energy more evenly because moisture helps improve heat transfer. This uniform heat distribution reduces the chance of heat accumulation, making skin temperature changes smoother and faster. Due to the presence of moisture, the skin's heat dissipation ability is improved. Blood flow and moisture level work together to promote heat transfer to other parts of the body, thereby accelerating the rate of skin temperature change. In addition, moist skin usually promotes blood flow (such as by accelerating metabolism or through temperature regulation reactions) and increases thermal conductivity. The unit of skin blood flow is milliliters per minute. When the blood supply to the skin is enhanced, the heat transfer efficiency is improved, and temperature fluctuations and changes will be more sensitive and rapid.

[0041] The unit of skin density is kilograms per cubic meter, and the value is usually 1000 kilograms per cubic meter, so this plan sets the skin density to 1000 kilograms per cubic meter; the unit of skin surface area is square meters.

[0042] The above units are only examples, and those skilled in the art may set different units according to actual needs when implementing this solution.

[0043] This embodiment solves the problem that traditional beauty devices lack an intelligent feedback mechanism. The present application can monitor the skin temperature change factor in real time, evaluate whether the skin is damaged, and dynamically adjust the working state of the microwave beauty device according to the detection results.

[0044] Embodiment 2: This embodiment includes all the contents of embodiment 1, and provides a temperature feedback-based controllable microwave beauty device. Figure 5 and Figure 6 shown.

[0045] In order to further improve the safety of using the microwave beauty instrument, when the skin damage assessment module assesses that the skin is not damaged, a reassessment is performed through the parts of the second embodiment.

[0046] A temperature feedback-based controllable microwave beauty device for skin contact, the device also includes a skin temperature assessment module;

[0047] The information storage submodule is also used to store the skin emissivity and transmit it to the control module;

[0048] The skin damage assessment module also transmits information that the skin is not damaged to the control module;

[0049] After receiving the information that the skin is not damaged, the control module starts calculating the skin radiation heat loss factor, which is obtained according to the skin emissivity, the surface area of ​​the skin, the skin temperature and the ambient temperature, and transmits the skin radiation heat loss factor to the skin temperature evaluation module;

[0050] The skin temperature evaluation module obtains information of whether the skin temperature is high or low according to the skin radiation heat loss factor, and transmits the information of whether the skin temperature is high or low to the communication module and the start-stop module;

[0051] The start-stop module sends a stop signal to the microwave beauty instrument according to the information of high skin temperature, and the microwave beauty instrument stops microwave output according to the stop signal;

[0052] The communication module transmits the information of high or low skin temperature to the user end.

[0053] Specifically, when the skin temperature evaluation module evaluates, the following principles are referred to: when the skin radiation heat loss factor is greater than or equal to the selection threshold of the skin radiation heat loss factor, it indicates that the skin temperature is high; when the skin radiation heat loss factor is less than the selection threshold of the skin radiation heat loss factor, it indicates that the skin temperature is appropriate; the selection threshold of the skin radiation heat loss factor is set by technical personnel in this field.

[0054] Optionally, when the control module calculates the skin radiation heat loss factor, the following formula is satisfied:

[0055] Fs=(5.67×10 -8 )×e×bmj×(1+ln(1+|temp skin -35℃|))×max(0,temp skin4 -temp e 4 ), where Fs is the skin radiation heat loss factor and e is the skin emissivity.

[0056] When the control module calculates the skin radiation heat loss factor, refer to the following program code:

[0057]

[0058]

[0059] Specifically, the value of skin emissivity is usually 0.965; when the skin temperature is higher than the ambient temperature, heat flows to the environment through radiation. If the skin temperature is lower than the ambient temperature, the thermal radiation will actually be zero. Therefore, when calculating the skin radiation heat loss factor, the corresponding situation should be when the skin temperature is greater than the ambient temperature.

[0060] The above units are only examples, and those skilled in the art may set different units according to actual needs when implementing this solution.

[0061] This embodiment solves the problem that the traditional beauty devices have relatively single functions. By introducing the calculation of the heat loss factor of the skin emissivity, the thermal state of the skin can be evaluated more accurately.

[0062] The contents disclosed above are only preferred feasible embodiments of the present invention, and do not limit the protection scope of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention description and drawings are included in the protection scope of the present invention. In addition, the elements therein can be updated as technology develops.
