Description

Technical Field

[0001] The present invention relates to the technical field of optical medical treatment, and in particular to a multifunctional hair growth instrument and a control method thereof. Background Art

[0002] Hair loss refers to the phenomenon of hair falling out. Normally, the hair that falls out is in the catagen and telogen phases. Since the hair that enters the catagen and the hair that enters the new growth phase is constantly in a dynamic balance, the normal amount of hair can be maintained. Pathological hair loss refers to abnormal or excessive hair loss, and there are many reasons for it. Usually, when the patient's hair secretes too much oil, it will clog the pores (excessive dandruff will also clog the pores), and severe cases will cause inflammation. Mild cases will compress the capillaries that supply nutrients, causing the hair to become thinner. Until the compressed blood vessels break, the supply of nutrients is completely stopped, resulting in hair loss.

[0003] In contemporary society, hair loss has become an important factor affecting the quality of life of hundreds of millions of people around the world, especially in urban areas with high work pressure and fast pace of life.

[0044] Embodiment 1

[0045] Figure 1 is a structural schematic diagram of a multifunctional hair growth device provided according to the present invention; Figure 2 It is a partial structural schematic diagram of a multifunctional hair growth device provided according to the present invention; Figure 3 Schematic diagram of the partial structure of another multifunctional hair growth device provided according to the present invention; this embodiment can be used to promote hair growth and prevent hair loss. Figures 1 to 3 The multifunctional hair growth device 100 provided in the embodiment of the present invention includes a helmet 11 and a red light module 112, a blue light module 115, a heating module 114 and a sensor module 12 distributed on the helmet 11; the red light module 112 is used to emit red light of a first preset wavelength; the blue light module 115 is used to emit blue light of a second preset wavelength; the heating module 114 is used for heating; the sensor module 12 includes an ultrasonic distance sensor 111 and a temperature sensor 113; wherein the ultrasonic distance sensor 111 is used to detect distance; and the temperature sensor 113 is used to detect temperature.

[0046] The red light module 112 may be a red light bead that can emit a wavelength of 640nm, the blue light module 115 may be a blue light bead that can emit a wavelength of 440nm, and the heating module 114 may be a heating blanket that evenly covers the inner side of the helmet. Under the premise that the functions of the above-mentioned modules of the present invention can be realized, this embodiment does not limit the specific settings of the red light module, the blue light module and the heating module.

[0047] Specifically, the spatial distribution of the helmet 11 is hemispherical. When the user wears the helmet 11 on the head, the helmet 11 can cover the top area, the temporal areas on both sides, the frontal areas on both sides and the occipital area. Multiple red light modules 112 and multiple blue light modules 115 are arranged in an array on the helmet 11 to ensure that the first preset wavelength red light emitted by the multiple red light modules 112 and the second preset wavelength blue light emitted by the multiple blue light modules 115 can fully cover the entire scalp area. The ultrasonic distance sensor 111 emits ultrasonic pulses through a transmitter. When these pulses encounter the user's scalp, they are reflected and captured by the receiver. Based on the time it takes for the reflected wave to return, the actual distance between the helmet 11 and the user's scalp can be calculated. When the actual distance is greater than a threshold distance, the ultrasonic distance sensor 111 sends a signal to turn off the multifunctional hair growth device 100; when the actual distance is less than the threshold distance, the ultrasonic distance sensor 111 sends a signal to turn on the multifunctional hair growth device 100. The actual distance between the helmet 11 and the user's scalp is obtained by the ultrasonic distance sensor 111 to determine whether the hair growth device is turned on or off. There is no need to manually turn the hair growth device on and off, which optimizes the user experience while saving unnecessary energy consumption and improving the life of the device. The heating module 114 heats the scalp to reach a preset temperature according to the actual scalp temperature detected by the temperature sensor 113. When the heat penetrates the scalp, it can dilate the blood vessels and increase the blood flow, thereby providing more nutrients and oxygen to the hair follicles. By adjusting the scalp temperature to maintain the ideal temperature of the treatment area, the hair follicle cells can be induced to produce heat shock proteins (HSPs). These proteins have the function of protecting cells from environmental stress (such as heat and oxidative stress) and helping the hair follicle cells maintain stability. HSPs can also help repair damaged cell structures, improve cell survival rates, prolong the growth period of hair follicles, and create a good environment for hair growth, thereby enhancing the hair growth effect of red light and blue light.

[0048] In an alternative embodiment, reference Figure 3 The array arrangement of the multiple red light modules 112 and the multiple blue light modules 115 can be a red light module column 1121 and a blue light module column 1151 arranged in sequence along the first direction X, wherein the red light module column 1121 is composed of a plurality of red light modules 112 equally spaced in the second direction Y, and the blue light module column 1151 is composed of a plurality of blue light modules 115 equally spaced in the second direction Y.

[0049] Exemplarily, the threshold distance for determining whether the multifunctional hair growth instrument 100 is turned on can be set to 5 cm. When the ultrasonic distance sensor 111 detects that the actual distance between the ultrasonic distance sensor 111 and the user's scalp is less than 5 cm, the multifunctional hair growth instrument 100 is powered on and started, and the red light module 112 and the blue light module 115 respectively emit 640 nm red light and 440 nm blue light to irradiate the user's scalp. The red light promotes the metabolism of the user's hair follicles and increases the blood circulation of the scalp. The blue light inhibits the oil secretion of the scalp and reduces the growth of bacteria. The heating module 114 heats the user's scalp according to the actual scalp temperature fed back by the temperature sensor 113 to reach the ideal temperature for hair growth, so that the blood vessels are dilated, the blood flow is increased, and the hair growth effect is improved. When the user takes off the helmet during the hair growth treatment, the ultrasonic distance sensor 111 detects that the actual distance between the ultrasonic distance sensor 111 and the user's scalp is greater than 5 cm, and then sends a signal to control the multifunctional hair growth instrument 100 to shut down and cut off the power.

[0050] The embodiment of the present invention sets a red light module, a blue light module, a heating module and a temperature sensor on the helmet of the multifunctional hair growth instrument 100. On the one hand, the red light module emits red light to promote hair follicle activation and blood circulation, and the blue light module emits blue light to inhibit scalp oil secretion and reduce bacterial growth. The combination of the two can better balance the scalp environment, which not only helps hair follicle regeneration, but also reduces the occurrence of infection and inflammation. On the other hand, the heating module heats the user's scalp according to the actual scalp temperature detected by the temperature sensor to maintain the ideal temperature of the treatment area, optimize the phototherapy environment, maximize the phototherapy effect, improve the effect of hair growth treatment, and improve scalp health and hair regeneration ability. In addition, the ultrasonic distance sensor detects the actual distance between the helmet and the user's scalp to determine whether to turn on or off the multifunctional hair growth instrument 100, which optimizes the user experience while saving unnecessary energy consumption and improving the life of the device.

[0051] Optional, reference Figure 4 The multifunctional hair growth device 100 further includes a massage module 13 distributed on the inner surface of the helmet; the massage module 13 includes a plurality of massage nodes 131 distributed at intervals, and the massage nodes 131 are used for massage.

[0052] Specifically, the massage nodes 131 distributed at intervals perform mechanical vibration to stimulate specific acupuncture points and areas of the scalp, such as the Baihui acupoint, the temple, and the Fengchi acupoint, to promote blood circulation in the scalp and bring more oxygen and nutrients to the hair follicles. At the same time, through massage, the lymphatic circulation of the scalp is also promoted, which helps to eliminate waste and toxins and improve the scalp environment. Mechanical stress acts on scalp cells and hair follicles, which can stimulate skin cells to secrete growth factors, such as vascular endothelial growth factor (VEGF) and transforming growth factor (TGF-β), which play an important role in the growth and repair of hair follicles. Among them, VEGF promotes angiogenesis and increases the nutrient supply of hair follicles; TGF-β participates in the growth cycle regulation of hair follicles and helps to extend the growth period of hair.

[0053] In an optional embodiment, multiple massage nodes 131 can work independently or collaboratively to provide different massage modes, and users can adjust the massage mode of the massage module 13 according to their needs to meet the personalized needs of users. Exemplarily, the massage module 13 may include a first massage mode, a second massage mode, and a third massage mode. Among them, the first massage mode is a low-intensity massage, which stimulates the Baihui acupoint, the temple and other areas to enhance local blood circulation, with a lighter force to avoid excessive stimulation; the second massage mode is a medium-intensity massage, which promotes scalp blood circulation, focuses on stimulating the Fengchi acupoint and the Baihui acupoint, helps relax and accelerates scalp metabolism; the third massage mode is a high-intensity massage, which stimulates multiple acupoints, especially the Baihui acupoint, the Fengchi acupoint, and the temple, to help relieve scalp tension and enhance the phototherapy effect.

[0054] The multifunctional hair growth device 100 of the embodiment of the present invention also includes a massage module, which includes a plurality of massage nodes arranged at intervals. Massaging the user's scalp through the massage module can improve the blood supply to the microenvironment around the hair follicles, stimulate the nerve endings of the scalp, regulate the autonomic nervous system, help relax tense scalp muscles, reduce pressure and pain on the scalp, use massage as an auxiliary action of phototherapy, accelerate the secretion of growth factors, further improve the scalp environment, provide better conditions for new hair growth, and enhance the hair growth treatment effect.

[0055] Optional, reference Figure 5 The multifunctional hair growth instrument 100 also includes an image recognition module 14, which includes a processing unit 141. The processing unit 141 is arranged on the helmet and is connected to the red light module 112, the blue light module 115, the heating module 114, the ultrasonic distance sensor 111 and the temperature sensor 113; the processing unit 14 is used to receive the user's scalp image to determine the proportion of the alopecia areata area to the scalp area, and determine a treatment plan according to the proportion, and control the working state of at least one of the red light module 112, the blue light module 115 and the heating module 114 based on the treatment plan.

[0056] Among them, the working states of the red light module 112, the blue light module 115 and the heating module 114 are divided into three working states, the first red light module working state is that the luminous power of the red light module 112 is 40%, the second red light module working state is that the luminous power of the red light module 112 is 70%, and the third red light module working state is that the luminous power of the red light module 112 is 100%; the first blue light module working state is that the luminous power of the blue light module 115 is 30%, the second blue light module working state is that the luminous power of the blue light module 115 is 60%, and the third red light module working state is that the luminous power of the blue light module 115 is 100%; the first heating module working state is that the target temperature of the heating module 114 is 37° C., the second heating module working state is that the target temperature of the heating module 114 is 41° C., and the third heating module working state is that the target temperature of the heating module 114 is 45° C. In different treatment plans, the working states of the red light module 112, the blue light module 115 and the heating module 114 are different.

[0057] Exemplarily, the treatment plan may include a mild alopecia areata treatment plan, a moderate alopecia areata treatment plan, and a severe alopecia areata treatment plan. The mild alopecia areata treatment plan sets the red light module 112, the blue light module 115, and the heating module 114 to work according to the first red light module working state, the first blue light module working state, and the first heating module working state, respectively; the moderate alopecia areata treatment plan sets the red light module 112, the blue light module 115, and the heating module 114 to work according to the second red light module working state, the second blue light module working state, and the second heating module working state, respectively; the severe alopecia areata treatment plan sets the red light module 112, the blue light module 115, and the heating module 114 to work according to the third red light module working state, the third blue light module working state, and the third heating module working state, respectively.

[0058] Specifically, after receiving the user's scalp image, the processing unit 14 pre-processes the scalp image, including operations such as denoising, enhancement, and smoothing, to improve the accuracy and robustness of subsequent processing. Usually, the scalp in the alopecia area is brighter and lighter in color, while the color of the normal hair-covered area is darker. By using data training, the processing unit 14 can automatically learn the characteristics of different types of scalps and hair, so as to accurately distinguish the alopecia area, the normal hair area, and possible skin problems. By analyzing the color difference of the scalp in the image, the color information of the scalp, hair, and alopecia area is extracted, and the convolutional neural network (CNN) in deep learning is used to perform image segmentation, calculate the pixel area of ​​the alopecia area in the image, and determine the severity of alopecia. According to the proportion of the alopecia area to the entire scalp area, the user's scalp condition is classified into mild, moderate, and severe alopecia. Then, a corresponding treatment plan is matched according to the user's scalp condition. The processing unit 14 controls the working state of at least one of the red light module 112, the blue light module 115 and the heating module 114 according to the treatment plan, and performs targeted hair growth treatment on the user's scalp, thereby improving the flexibility and accuracy of the treatment of the multifunctional hair growth device 100.

[0059] It should be noted that the processing unit can be a single-chip microcomputer, which is called a single-chip microcomputer. It is an integrated circuit chip. It integrates the central processing unit CPU with data processing capabilities, random access memory RAM, read-only memory ROM, multiple I / O ports and interrupt systems, timer / counter and other functions, and may even include display drive circuits, pulse width modulation circuits, analog multiplexers, A / D converters and other circuits on a silicon chip, forming a small and complete microcomputer system. The small size, light weight and low price of single-chip microcomputers provide convenient conditions for learning, application and development.

[0060] Exemplarily, when the area of ​​alopecia areata accounts for 5% to 30% of the total scalp area, it is determined that the user's scalp condition is mild alopecia areata, and the processing unit 14 adopts a mild alopecia areata treatment plan to control the red light module 112, the blue light module 115 and the heating module 114, and controls the working power of the red light module 112 to 40%, and uses red light with a wavelength of 640nm to promote blood circulation and cell metabolism, and help activate the remaining hair follicles. The working power of the blue light module is controlled to 30%, and blue light with a wavelength of 440nm is used to inhibit possible subtle inflammation and control sebum secretion. The heating target temperature of the heating module 114 is controlled to 37°C, which is close to the lower limit of the ideal temperature for scalp growth, which helps to activate the hair follicles without causing overheating. When the area of ​​alopecia areata accounts for 30% to 50% of the total scalp area, it is determined that the user's scalp condition is moderate alopecia areata. The processing unit 14 adopts a moderate alopecia areata treatment plan to control the red light module 112, the blue light module 115 and the heating module 114. The working power of the red light module 112 is controlled to 70%, and red light with greater light intensity is used to penetrate into the hair follicle layer to further promote blood flow, accelerate the recovery of hair follicles and the growth of new hair. The working power of the blue light module is controlled to 60% to increase the anti-inflammatory function and regulate overactive sebaceous glands to prevent scalp oil accumulation. The heating target temperature of the heating module 114 is controlled to 41°C to maintain a suitable ambient temperature to help hair follicles recover and enhance the phototherapy effect. When the area of ​​alopecia areata accounts for more than 50% of the entire scalp area, it is determined that the user's scalp condition is severe alopecia areata, and the processing unit 14 adopts a severe alopecia areata treatment plan to control the red light module 112, the blue light module 115 and the heating module 114, and controls the working power of the red light module 112 to be 100%, and the red light output intensity of the red light module 112 is the maximum, which promotes blood circulation and stimulates hair follicle regeneration, and helps repair severely damaged areas. The working power of the blue light module is controlled to be 100%, and the blue light output intensity of the blue light module 115 is the maximum, which effectively reduces scalp inflammation and inhibits the growth of fungi and bacteria. The heating target temperature of the heating module 114 is controlled to be 45°C, which provides a slightly higher temperature, enhances blood circulation, and combines high-intensity red light therapy to maximize the activation of scalp hair follicles.

[0061] The multifunctional hair growth device 100 of the embodiment of the present invention further includes an image recognition module, which receives a user's scalp image through a processing unit in the image recognition module, processes the user's scalp image, determines the ratio of the alopecia areata area to the scalp area, and determines a treatment plan based on the ratio, thereby controlling the working state of at least one of the red light module, the blue light module, and the heating module. According to different types of scalp conditions, targeted treatment plans are implemented to meet the personalized needs of users and improve the flexibility and accuracy of the treatment of the multifunctional hair growth device 100.

[0062] Optional, continue to refer to Figure 5The image recognition module 14 also includes a camera 142; the camera 142 is used to obtain a user's scalp image.

[0063] Specifically, the camera 142 is connected to the processing unit 141, and takes photos of the front, left side, side and top of the head, and transmits them to the processing unit 141. By shooting at multiple angles, it can be ensured that every part of the scalp is captured, so that no area with possible problems is missed. Combining photos from different angles, a three-dimensional image of the scalp can be constructed by the processing unit 141, which is convenient for subsequent in-depth analysis and processing, greatly enhancing the comprehensiveness and accuracy of the scalp condition judgment, and improving the treatment efficiency and effect of hair growth treatment.

[0064] Optional, reference Figure 6 The multifunctional hair growth device 100 further includes a warning module 15, which is connected to the temperature sensor 113; the warning module 15 is used to issue a warning message when the temperature is greater than a first preset temperature.

[0065] Specifically, the first preset temperature can be 45°C. When the temperature sensor detects that the actual temperature of the user's scalp is greater than 45°C, a warning reminder can be issued. The warning reminder may include but is not limited to at least one of a voice reminder, a buzzer reminder, a light reminder, etc., so that the user can promptly know that the actual temperature of the scalp exceeds the normal temperature range and adopt corresponding countermeasures, such as manually turning off the multifunctional hair growth device 100 or removing the multifunctional hair growth device 100 from the head, so as to improve the safety of the operation of the multifunctional hair growth device 100.

[0066] Optional, reference Figure 7 The multifunctional hair growth instrument 100 also includes a communication module 16 and a user terminal 17; the communication module 16 is arranged on the helmet, and is respectively connected to the red light module 112, the blue light module 115, the heating module 114 and the user terminal 17. The user terminal 17 sends control instructions to the red light module 112, the blue light module 115 and the heating module 114 based on the communication module 16 to adjust the working states of the red light module 112, the blue light module 115 and the heating module 114.
