[0060] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order different from those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0061] The embodiment of the present invention provides a dynamic regulation method of an intelligent hair dryer, Figure 1 It is a flowchart of a dynamic regulation method of an intelligent hair dryer provided by the embodiment of the present invention. Refer to Figure 1 , the dynamic regulation method of the intelligent hair dryer includes:

[0062] S110. Obtain multi-dimensional feature information of the hair drying target, where the multi-dimensional feature information includes at least two of the hair feature information, skin feature information, temperature distribution information of the hair drying target, and the distance from the intelligent hair dryer to the hair drying target.

[0063] S120. Switch the working mode of the intelligent hair dryer according to the multi-dimensional feature information; wherein, the working modes of the intelligent hair dryer include at least two of a normal mode, a care mode, and a protection mode; under different working modes, at least one of the air outlet speed range, the air outlet temperature range, and the type of essential oil sprayed by the intelligent hair dryer is different.

[0064] Specifically, Figure 2 is a structural block diagram of an intelligent hair dryer provided by an embodiment of the present invention. Refer to Figure 2 , the intelligent hair dryer includes a main control MCU module 1 and a fan unit 10, a heating circuit unit 20, and an essential oil atomization unit 30 connected to the main control MCU module 1; the fan unit 10 is used to output air to the object to be blown; the heating circuit unit 20 is used to adjust the blowing temperature of the intelligent hair dryer; the essential oil atomization unit 30 is used to spray essential oil to the object to be blown. The intelligent hair dryer further includes a multi-dimensional information acquisition unit 2, and the multi-dimensional information acquisition unit 2 is used to acquire the multi-dimensional feature information of the object to be blown and send the multi-dimensional feature information to the main control MCU module 1, so as to switch the working mode of the intelligent hair dryer according to the multi-dimensional feature information through the main control MCU module 1.

[0065] The object to be blown can be the user's head, hair, or other objects to be blown. The multi-dimensional feature information of the object to be blown includes at least two of the hair feature information, skin feature information, temperature distribution information, and the distance from the intelligent hair dryer to the object to be blown of the object to be blown. The temperature distribution information can be understood as the temperature of different blown positions of the object to be blown. Under different working modes, at least one of the air outlet speed range, the air outlet temperature range, and the type of essential oil sprayed by the intelligent hair dryer is different; by regulating the air outlet speed range, the air outlet temperature range, and the type of essential oil sprayed by the intelligent hair dryer, the switching of the working mode of the intelligent hair dryer is realized.

[0066] The main problems existing in traditional hair dryers during actual use include: local overheating problem. When the user continuously blows a certain area for a long time, heat will accumulate rapidly, which may cause the local temperature to exceed the safe range, resulting in a burning sensation and even minor burns; the problem that distance affects temperature. Different distances between the hair dryer and the object to be blown will cause a large difference in the actual temperature. When the distance is too close, the temperature of the blown area of the object to be blown may exceed the safe range, causing damage to the hair and scalp; the problem of moisture loss. When using hot air to blow the object to be blown, it will inevitably cause a large amount of moisture in the hair to be lost, resulting in dry and frizzy hair and affecting the health and gloss of the hair.

[0067] For the technical solution provided by the embodiment of the present invention, the intelligent hair dryer is provided with at least two working modes. Under different working modes, at least one of the air outlet speed range, air outlet temperature range, and type of essential oil sprayed by the intelligent hair dryer is different. Before selecting the working mode of the intelligent hair dryer, by obtaining the multi-dimensional feature information of the object to be blown, the characteristics and actual situation of the object to be blown (such as hair and scalp) can be analyzed from multiple aspects, providing a basis for the switching of the working mode, thereby realizing the customization of personalized care solutions, significantly improving the functionality of the hair dryer and the user experience, and providing a safer, more comfortable and intelligent hair care process for users.

[0068] Based on the above embodiment, Figure 3 is a structural block diagram of another intelligent hair dryer provided by the embodiment of the present invention. Refer to Figure 3 , optionally, the intelligent hair dryer includes an image acquisition unit 40; obtaining the multi-dimensional feature information of the object to be blown includes: collecting an image of the object to be blown by the image acquisition unit 40; identifying the hair feature information and skin feature information of the object to be blown according to the image of the object to be blown; wherein, the hair feature information includes at least one of hair color depth, hair density, hair dryness and wetness, and hair quality state; the skin feature information includes the scalp health state.

[0069] And / or, the intelligent hair dryer includes a temperature detection unit 50; obtaining the multi-dimensional feature information of the object to be blown includes: obtaining the temperature distribution information of the object to be blown by the temperature detection unit 50.

[0070] And / or, the intelligent hair dryer includes a distance detection unit 60; obtaining the multi-dimensional feature information of the object to be blown includes: obtaining the distance from the intelligent hair dryer to the object to be blown by the distance detection unit 60.

[0071] Specifically, an image acquisition unit 40 can be integrated on the intelligent hair dryer. The image acquisition unit 40 can include a camera. When the intelligent hair dryer is powered on and enters the blowing state, the main control MCU module 1 can control the camera to collect images of the area being blown in real time or at a preset frequency, so as to be able to collect images of the target being blown from different angles and / or different distances, that is, obtain the hair feature information and skin feature information of the target being blown in all directions, and dynamically adjust the working mode of the intelligent hair dryer according to the actual conditions of different positions of the target being blown. When the target being blown is the user's head, the hair feature information is the hair feature information, and the skin feature information is the scalp feature information. In some embodiments, the main control MCU module 1 can control the camera to collect images of the target being blown when receiving an image acquisition instruction, so as to reduce the number of acquired images of the target being blown and reduce the difficulty of data processing. Among them, the resolution of the camera can be a high-resolution camera greater than a preset resolution value to ensure capturing detailed hair and scalp images and accurately presenting the hair quality and scalp condition. The preset resolution value can be set according to the actual situation. In addition, a camera that supports fast autofocus and image enhancement functions in low-light environments can be used to ensure clear images can be obtained in different environments.

[0072] A temperature detection unit 50 can be integrated on the intelligent hair dryer. The temperature detection unit 50 can include an infrared temperature sensor. The infrared temperature sensor is a non-contact sensor that uses the principle of infrared radiation to measure the surface temperature of an object and has high detection accuracy. When the intelligent hair dryer is powered on and enters the blowing state, the main control MCU module 1 controls the temperature detection unit 50 to detect the blowing area in real time or at a preset frequency, so as to be able to collect temperature data of the target being blown from different angles, and thus obtain the temperature distribution information of the target being blown, and dynamically adjust the working mode of the intelligent hair dryer according to the actual temperature of different positions of the target being blown.

[0073] A distance detection unit 60 can be integrated on the intelligent hair dryer. The distance detection unit 60 includes a distance sensor. By equipping the intelligent hair dryer with a distance sensor, the distance between the intelligent hair dryer and the target being blown (such as hair) can be monitored in real time. Combining with an intelligent control algorithm, the working mode of the intelligent hair dryer can be dynamically adjusted to provide a safer and more scientific hair drying experience for users. The main control MCU module 1 can also have the function of filtering environmental interference. After the distance sensor sends distance data to the main control MCU module 1, the main control MCU module 1 can filter the environmental data to ensure that the output is adjusted only when the intelligent hair dryer is close to the target being blown, avoiding misoperation or ineffective adjustment.

[0074] Figure 4 is a flowchart of another dynamic regulation method of the intelligent hair dryer provided by the embodiment of the present invention. Refer to Figure 4, when the multi-dimensional feature information of the object to be dried includes hair feature information, skin feature information, temperature distribution information, and the distance from the intelligent hair dryer to the object to be dried, the dynamic regulation method of the intelligent hair dryer includes:

[0075] S210. Collect the image of the object to be dried by the image acquisition unit, and identify the hair feature information and skin feature information of the object to be dried according to the image of the object to be dried; wherein, the hair feature information includes at least one of hair color depth, hair density, hair dryness and wetness, and hair quality state; the scalp feature information includes the scalp health state.

[0079] Wherein, the working modes of the intelligent hair dryer include a normal mode, a care mode, and a protection mode; in different working modes, at least one of the air outlet speed range, air outlet temperature range, and type of essential oil sprayed by the intelligent hair dryer is different.

[0080] Specifically, obtaining the multi-dimensional feature information of the object to be dried includes: collecting the image of the object to be dried by the image acquisition unit 40, and identifying the hair feature information and skin feature information of the object to be dried according to the image of the object to be dried; obtaining the temperature distribution information of the object to be dried by the temperature detection unit 50; obtaining the distance from the intelligent hair dryer to the object to be dried by the distance detection unit 60.

[0081] Wherein, in the process of identifying the hair feature information and skin feature information of the object to be dried according to the image of the object to be dried, the specific steps of identifying the hair color include: a1. Obtain the image of the object to be dried; a2. Use the color space conversion and separation algorithm to obtain the RGB hue information and brightness information at different positions in the image of the object to be dried; a3. Determine the main component and depth distribution of the hair hue through the histogram; a4. Determine the hair color level according to the preset threshold of different color levels; the hair color level can include white, light color, medium, and dark. After determining the hair color level, the working parameters such as the corresponding wind speed and air outlet temperature of the intelligent hair dryer can be adjusted according to the hair color level.

[0082] The specific steps for identifying hair volume density include: b1. Obtain the image of the target being blow-dried; b2. Use an edge detection algorithm to extract the hair contour features; b3. Count the hair volume and calculate the hair coverage ratio per unit area; b4. Determine the hair volume density level of the target being blow-dried according to the calculation result and the hair coverage ratio range corresponding to different hair volume density levels; wherein, the hair volume density levels can include: sparse, medium, and thick. After determining the hair volume density level, the working parameters such as the corresponding wind speed and outlet air temperature of the intelligent hair dryer can be adjusted according to the hair volume density level.

[0083] The specific steps for identifying the dryness and wetness of hair include: c1. Obtain the image of the target being blow-dried; c2. Extract the image brightness features and determine the reflected light intensity and texture smoothness of the hair according to the brightness features; c3. Compare with the dry-wet state feature template to match the corresponding dryness and wetness of the hair; the dryness and wetness of the hair can include wet, dry, etc. After determining the dryness and wetness of the hair, the working parameters such as the corresponding essential oil amount, wind speed, and outlet air temperature of the intelligent hair dryer can be adjusted according to the dryness and wetness of the hair. For example, when the dry state is detected as opposed to the detected wet state, the wind speed and outlet air temperature can be reduced and the essential oil amount can be increased.

[0084] The specific steps for identifying skin feature information include: d1. Obtain the image of the target being blow-dried and at the same time obtain the infrared temperature sensor data; d2. Use skin color segmentation technology to extract the scalp area and compare with the erythema or abnormal color patch feature template to determine whether there is an abnormal area; d3.

After determining the skin feature information, the working parameters such as the corresponding wind speed and outlet air temperature of the intelligent hair dryer can be adjusted according to the skin feature information.

[0085] In the embodiments of the present invention, by integrating modules such as a camera, an infrared temperature sensor, and a distance sensor, a comprehensive perception of the user's hair color, hair volume density, temperature distribution, and dry-wet state is realized; it can also detect in real time the area where the intelligent hair dryer blows and the distance between the intelligent hair dryer and the hair, and combine algorithms to dynamically switch the working mode of the intelligent hair dryer to adjust the output parameters, including temperature, wind speed, and atomized essential oil amount, etc., effectively avoiding problems such as local overheating, too high temperature, and hair moisture loss, and providing a safer, more accurate, and milder hair drying and hair care experience for users.

[0086] On the basis of the above embodiments, optionally, switching the working mode of the intelligent hair dryer according to multi-dimensional feature information includes: judging whether there is a protection mode trigger information in the multi-dimensional feature information; if so, switching the working mode of the intelligent hair dryer to the protection mode; if not, maintaining the current working mode, where the current working mode is the normal mode or the care mode. Figure 5It is a flowchart of another dynamic regulation method of the intelligent hair dryer provided by the embodiment of the present invention. Refer to Figure 5 , the dynamic regulation method of the intelligent hair dryer includes:

[0087] S310. Obtain multi-dimensional feature information of the target being blown, where the multi-dimensional feature information includes hair feature information, skin feature information, temperature distribution information of the target being blown, and the distance from the intelligent hair dryer to the target being blown.

[0088] S320. Determine whether protection mode trigger information appears in the multi-dimensional feature information; if so, execute step S330, if not, execute step S340.

[0089] S330. Switch the working mode of the intelligent hair dryer to the protection mode.

[0090] S340. Maintain the current working mode and return to execute step S310; where the current working mode is the normal mode or the care mode.

[0091] Specifically, the protection mode trigger information includes that the hair color depth is light, the scalp health status is scalp allergy or swelling, the hair density is less than a preset density threshold, there is a position in the target being blown where the temperature is greater than a preset temperature threshold, and the distance from the intelligent hair dryer to the target being blown is less than a preset distance threshold. When any one or more of the hair color depth being light, the scalp health status being scalp allergy or swelling, the hair density being less than the preset density threshold, there being a position in the target being blown where the temperature is greater than the preset temperature threshold, and the distance from the intelligent hair dryer to the target being blown being less than the preset distance threshold appear in the multi-dimensional feature information, switch the working mode of the intelligent hair dryer to the protection mode. In the protection mode, the air outlet speed and air outlet temperature of the intelligent hair dryer are both greater than those in the normal mode and the care mode. Exemplarily, in the normal mode and the care mode, the temperature control system sets the air outlet temperature range to 55°C - 58°C; in the protection mode, the temperature control system adjusts the air outlet temperature range to 47 - 50°C to avoid discomfort or damage caused by high temperature.

[0092] Further, the initial state of the intelligent hair dryer after startup is the normal mode. The dynamic regulation method of the intelligent hair dryer further includes: after confirming that the intelligent hair dryer is started up, controlling the working mode of the intelligent hair dryer to be the normal mode. A mode switching module can be integrated on the intelligent hair dryer, and the user can switch the working mode of the intelligent hair dryer from the normal mode to the care mode through the mode switching module, or can also exit the care mode and restore the normal mode. In the care mode, the sprayed essential oil is of the first type; in the normal mode and the protection mode, the sprayed essential oil is of the second type. Among the working parameters of the care mode and the normal mode, at least the type of the sprayed essential oil is different. When the intelligent hair dryer is in the normal mode or the care mode, if the protection mode trigger information appears in the obtained multi-dimensional feature information, it automatically enters the protection mode to reduce the air outlet speed and air outlet temperature to protect the user's hair and scalp.

[0093] Based on the above embodiments, optionally, switching the working mode of the intelligent hair dryer according to the multi-dimensional feature information includes: judging whether the protection mode trigger information appears in the multi-dimensional feature information; if so, switching the working mode of the intelligent hair dryer to the protection mode; if not, judging whether the care mode trigger information appears in the multi-dimensional feature information, if so, switching the working mode of the intelligent hair dryer to the care mode, and if not, switching the working mode of the intelligent hair dryer to the normal mode.

[0101] S460. Switch the working mode of the intelligent hair dryer to the care mode and return to execute step S420.

[0102] S470. Keep the working mode of the intelligent hair dryer as the normal mode and return to execute step S420.

[0103] Specifically, after confirming that the intelligent hair dryer is turned on, control the working mode of the intelligent hair dryer to be the normal mode. Obtain the multi-dimensional feature information of the hair drying target, and switch the working mode of the intelligent hair dryer according to the multi-dimensional feature information. The specific steps include: determining whether a protection mode trigger message appears in the multi-dimensional feature information; if so, switch the working mode of the intelligent hair dryer to the protection mode; if not, determine whether a care mode trigger message appears in the multi-dimensional feature information. If so, switch the working mode of the intelligent hair dryer to the care mode. If not, switch the working mode of the intelligent hair dryer to the normal mode.

[0104] Among them, the protection mode trigger information includes any one or more of the hair color depth being light, the scalp health status being scalp allergy or swelling, the hair density being less than the preset density threshold, the position with a temperature greater than the preset temperature threshold in the hair drying target, and the distance between the intelligent hair dryer and the hair drying target being less than the preset distance threshold; the care mode trigger information includes the hair quality status being a damaged hair quality status; in the care mode, the essential oil sprayed by the intelligent hair dryer is the first type of essential oil; in the normal mode and the protection mode, the essential oil sprayed by the intelligent hair dryer is the second type of essential oil; in the protection mode, the air outlet speed and air outlet temperature of the intelligent hair dryer are both less than the air outlet speed and air outlet temperature in the normal mode and the care mode.

[0105] The technical solution provided by the embodiment of the present invention sets the working modes of the intelligent hair dryer to include three working modes: normal mode, care mode, and protection mode. Before selecting the working mode of the intelligent hair dryer, by obtaining the multi-dimensional feature information of the hair drying target and first judging the protection mode trigger information. If the protection mode trigger information does not appear in the multi-dimensional feature information, then judge the trigger information of the care mode. If neither appears, continue to maintain the normal mode. By setting the judgment priority of each mode trigger information, automatic switching between the three modes is realized, significantly improving the functionality of the hair dryer and the user experience, and providing a safer, more comfortable and intelligent hair care process for users.

[0106] Based on the above embodiments, optionally, the multi-dimensional feature information further includes user age information; the protection mode trigger information further includes that the user age is less than a preset age threshold; while identifying the hair feature information and skin feature information of the target being blown based on the target image being blown, it further includes: identifying the user's head shape based on the target image being blown; determining the user age information according to the user's head shape.

[0107] Specifically, the specific steps for identifying the user's head shape information include: e1. Obtain the head contour image of the user through the image acquisition unit; e2. Analyze the head size and proportion using the head shape detection model; e3. Compare the head shape feature templates of children and adults to determine whether the user's head shape is a child's head shape or an adult's head shape. If the user's head shape is a child's head shape, it means that the current user's age is less than or equal to the preset age, and the preset age is, for example, the maximum value of the child age stage. In the case where it is determined that the current user's age is less than the preset age based on the user's head shape information, the working mode of the intelligent hair dryer is controlled to switch to the protection mode to reduce the air outlet speed and air outlet temperature of the intelligent hair dryer and reduce the risk of burning the child's scalp.

[0108] Based on the above embodiments, the essential oil atomization unit 30 includes a first essential oil tank and a second essential oil tank; the first essential oil tank is used to store the first type of essential oil, and the second essential oil tank is used to store the second type of essential oil. When the intelligent hair dryer is in the care mode, the main control MCU module 1 controls the essential oil atomization unit 30 to spray out the first type of essential oil; when the intelligent hair dryer is in the normal mode and the protection mode, the main control MCU module 1 controls the essential oil atomization unit 30 to spray out the second type of essential oil.

[0109] Specifically, the ceramic chip high-speed oscillation technology can be adopted to decompose the essential oil into finer and smaller molecules that are more easily absorbed by the hair, thereby improving the hair care effect. The intelligent hair dryer can be built-in with two types of essential oils, where the first type of essential oil is a nourishing hair care essential oil, and the second type of essential oil is a light water-locking hair care essential oil, and the essential oil atomization output can be intelligently selected and controlled according to user needs. For example, control the type of essential oil output by the essential oil atomization unit 30 according to the hair quality state.

[0110] Furthermore, the dynamic regulation method of the intelligent hair dryer further includes: in the normal mode, care mode, and protection mode, detect the time for the intelligent hair dryer to continuously spray essential oil at the same position of the target being blown. If the time for continuously spraying essential oil at the same position of the target being blown is greater than or equal to the first preset time, suspend the spraying of the essential oil.

[0111] Specifically, when the hair quality is not damaged (e.g., in the normal mode), a lightweight water-locking hair essential oil is used. The blowing area is detected in real time through a camera to determine whether the hair quality state is that the hair quality is not damaged. If so, the lightweight water-locking hair essential oil can be sprayed timely two minutes before the start of blowing, for example, so that it evenly adheres to the hair surface to form a protective film, preventing the loss of hair moisture caused by blowing, thereby avoiding hair dryness and frizz. After starting to blow, control the essential oil atomization unit 30 to spray the lightweight water-locking hair essential oil. During the hair drying process, if it is detected that the same position is continuously blown for more than 1 second, the spraying of the essential oil is paused to avoid the hair becoming greasy or sticky due to excessive essential oil, ensuring a natural and healthy hair care effect.

[0112] When the hair quality is damaged (in the care mode), a nourishing hair essential oil is used. The blowing area is detected in real time through a camera to determine whether the hair quality state is that the hair quality is damaged. If so, the nourishing hair essential oil can be sprayed timely two minutes before the start of blowing, for example, so that it evenly adheres to the hair surface to form a protective film, preventing the loss of hair moisture caused by blowing, thereby avoiding hair dryness and frizz. After starting to blow, control the essential oil atomization unit 30 to spray the nourishing hair essential oil to deeply moisturize and repair the hair. During the hair drying process, if it is detected that the same position is continuously blown for more than 3 seconds, the spraying of the essential oil is paused to avoid the hair becoming greasy or sticky due to excessive essential oil, ensuring a natural and healthy hair care effect.

[0113] Both essential oils are stored in independent essential oil tanks, and a liquid level detection module can be equipped to detect the remaining amount of the essential oil. When the liquid level is too low, the intelligent hair dryer will issue a voice alarm to remind the user to replenish the essential oil in time to ensure the continuity and high efficiency of the hair care function. Further, during the use of the essential oil, the camera and the distance sensor can work together to accurately identify the hair care area and distance, and automatically spray the essential oil at an appropriate position. When it is detected that the intelligent hair dryer leaves the hair area, control the essential oil atomization unit 30 to stop the atomization and output of the essential oil to effectively avoid waste of the essential oil. The technical solution provided by the embodiment of the present invention realizes an intelligent, efficient and economical essential oil atomization hair care function through the above design, provides a comprehensive hair drying and care experience for users, and further enhances the practicality and market competitiveness of the product.

[0114] Based on the above embodiments, Figure 7 is a structural block diagram of another intelligent hair dryer provided by the embodiment of the present invention. Refer to Figure 7 , optionally, the intelligent hair dryer further includes a light therapy unit 70; the dynamic regulation method of the intelligent hair dryer further includes:

[0115] When the intelligent hair dryer switches to the normal mode, regulate the light emitted by the light therapy unit 70 to be blue light;

[0116] When the intelligent hair dryer switches to the care mode, the light emitted by the phototherapy unit 70 is regulated to be red light;

[0117] When the intelligent hair dryer switches to the protection mode, the light emitted by the phototherapy unit 70 is regulated to be blue light.

[0118] Specifically, the intelligent hair dryer further includes a phototherapy unit 70, which is electrically connected to the main control MCU module 1. The main control MCU module 1 controls the phototherapy unit 70 to emit light. The phototherapy unit 70 may include multiple red LEDs for emitting red light and multiple blue LEDs for emitting blue light. Among them, the range of the red light wavelength is 630nm - 660nm, and the range of the blue light wavelength is 405nm - 470nm. Different colors of light have different effects. Red light is used to promote the activity and metabolism of hair follicle cells, stimulate blood circulation to provide more nutrients and oxygen for hair follicles, and repair damaged hair follicle cells and delay hair follicle degeneration; blue light is used to inhibit the growth of scalp bacteria to reduce inflammation and dandruff, and improve the balance of scalp oil secretion.

[0119] Based on the above embodiments, referring to Figure 7 , optionally, the intelligent hair dryer further includes an anion generator 80, and the dynamic regulation method of the intelligent hair dryer further includes:

[0120] While controlling the intelligent hair dryer to blow air, start the anion generator 80 to release anions.

[0121] Specifically, the intelligent hair dryer further includes an anion generator 80, which is electrically connected to the main control MCU module 1. By controlling the anion generator 80 to release anions through the main control MCU module 1, the positive charges in the hair can be effectively neutralized, thereby reducing the frizzy and entangled phenomena of the hair caused by static electricity, and significantly improving the smoothness and combability of the hair. Moreover, anions can quickly penetrate to the surface of the hair strands, balance the moisture distribution in the hair strands, enhance the softness and natural luster of the hair, and reduce the moisture loss during the drying process. Long-term use of the anion function can effectively reduce hair quality damage and protect the integrity of the hair strand structure. By setting the intelligent hair dryer to default start the anion generator 80 in the blowing state, it is ensured that the antistatic protection function is available every time the intelligent hair dryer is used to blow hair. Users can adjust the anion output concentration according to personal needs to adapt to their specific requirements. Optionally, when the anion generator 80 fails or malfunctions, control the anion generator 80 to stop using and remind the user to perform maintenance through voice. The technical solution provided by the embodiments of the present invention realizes multiple functions of antistatic, smooth hair care and hair quality improvement during the hair drying process through the integration of anion technology, effectively improves the user experience, and makes hair care more efficient and intelligent.

[0122] Based on the above embodiments, optionally, in the normal mode, the care mode, and the protection mode, the outlet air temperature is dynamically adjusted according to the temperature distribution information of the object to be blown, and / or the outlet air temperature and / or the outlet air speed are dynamically adjusted according to the distance between the intelligent hair dryer and the object to be blown.

[0123] Specifically, the intelligent hair dryer is equipped with a distance sensor. In the normal mode, the care mode, and the protection mode, it can real-time monitor the distance between the intelligent hair dryer and the object to be blown (such as hair), and combine with the intelligent control algorithm to dynamically adjust the working parameters of the intelligent hair dryer, providing a safer and more scientific hair drying experience for users. When it detects that the device is close to the hair, it automatically reduces the temperature and wind speed output to avoid burns or dryness caused by excessive local heat. When the device is at a relatively far distance, it appropriately increases the wind speed and temperature to ensure uniform heat distribution and achieve fast drying. Among them, the data accuracy collected by the distance sensor can reach the millimeter level to provide a more accurate and intelligent temperature control experience and risk control experience.

[0124] The intelligent hair dryer is equipped with an infrared temperature sensor for real-time detecting the temperature of the hair and the scalp. In the normal mode, the care mode, or the protection mode, when it detects that the scalp or hair temperature is close to the safety upper limit, the main control MCU module 1 will control to reduce the heating power of the heating circuit unit 20 or stop heating to switch to the cold wind mode to prevent overheating from damaging the hair quality and the scalp. If it detects an abnormal temperature rise (such as the temperature continuously exceeding the standard range), the main control MCU module 1 controls the heating circuit unit 20 to stop heating and reminds the user through voice or flashing lights to ensure safety. Among them, the detection error of the infrared temperature sensor is within -0.5°C to 0.5°C to provide a more accurate and intelligent temperature control experience and ensure that the heat output by the intelligent hair dryer is always within the safe range.

[0125] Among them, the heating circuit unit 20 can include at least two independently controlled heating core systems, which can intelligently adjust the number of heating cores started and the heating power of the heating cores according to the information and data provided by the camera and the distance sensor (such as the intelligent hair dryer being close to the hair, the blowing time in the same area, and the dry and wet state of the hair). In addition, the heating circuit unit 20 includes at least two independently controlled heating core systems. Even if a single core fails, the heating function of the heating circuit unit 20 can still operate normally, thereby further improving the safety, stability, and user experience of the intelligent hair dryer.

[0126] The fan unit 10 can include a fan and a brushless DC motor drive circuit for driving the fan to rotate. The brushless DC motor drive circuit is electrically connected to the main control MCU module 1, and the main control MCU module 1 is used to control the DC motor drive circuit to drive the fan to rotate. The fan unit 10 supports multi-level adjustment and has the characteristics of low noise and high lifespan to ensure the comfort and durability of hair drying.

[0127] Based on the above embodiments, Figure 8 is a structural block diagram of another intelligent hair dryer provided by an embodiment of the present invention. Refer to Figure 8 , optionally, the intelligent hair dryer further includes a key unit 90; the dynamic regulation method of the intelligent hair dryer further includes: switching the working mode of the intelligent hair dryer according to a key command triggered by the key unit 90, and / or adjusting at least one of the air outlet temperature, air outlet speed, and essential oil type sprayed in each working mode of the intelligent hair dryer;

[0128] and / or, the intelligent hair dryer further includes a voice interaction unit 100, and the dynamic regulation method of the intelligent hair dryer further includes: switching the working mode of the intelligent hair dryer according to a voice command received by the voice interaction unit 100, and / or adjusting at least one of the air outlet temperature, air outlet speed, and essential oil type sprayed in each working mode of the intelligent hair dryer.

[0129] Specifically, both the key unit 90 and the voice interaction unit 100 are connected to the main control MCU module 11. Among them, the key unit 90 includes multiple keys, and the multiple keys can be set on the surface of the intelligent hair dryer. Exemplarily, the multiple keys include a power switch key, a setting key, a speed-up key, and a speed-down key. The power switch key is used to control the power on and off of the intelligent hair dryer. After the intelligent hair dryer is powered on, by default, the speed-up key and the speed-down key are used to control the wind speed of the wind output by the fan unit 10. The speed-up key is used to control an increase in the wind speed of the wind output by the fan unit 10, and the speed-down key is used to control a decrease in the wind speed of the wind output by the fan unit 10. Press the setting key once briefly, and the speed increase and decrease are adjusted to control the heating temperature of the heating circuit unit 20. The speed-up key is used to control an increase in the heating temperature of the heating circuit unit 20, and the speed-down key is used to control a decrease in the heating temperature of the heating circuit unit 20; press the setting key once again briefly, and the speed-up key and the speed-down key are restored to control the wind speed of the wind output by the fan unit 10. The setting key can also be used for mode selection. For example, after the intelligent hair dryer is powered on, it is in the normal mode by default. Long press the setting key to enter or exit the care mode. Through a simple and intuitive key design, users can quickly select the appropriate working mode, wind speed, and temperature range. The time range for short presses and the time range for long presses can be set according to actual needs.

[0130] The voice interaction unit 100 has two core functions: voice commands and voice reminders, aiming to provide users with an intelligent and convenient operation experience. Corresponding to the voice command function, users can start the device through a customized voice wake-up word. For example, setting the wake-up word to "Xiaofeng Xiaofeng", when the device detects the wake-up word, it will play a prompt tone "I'm here", indicating that the device has entered the voice command mode. After waking up, users can issue operation commands such as "Enter the care mode" or "Lower the temperature", and the device will perform corresponding function operations according to the commands. The voice recognition technology supports rich command content and can flexibly adjust the command set content according to user needs. For the voice reminder function, the device provides real-time voice feedback during operation, such as "The current temperature has been adjusted to 60°C" or "The level of the nourishing hair care essential oil is insufficient, please replenish it in time". The reminder content can cover changes in the working parameters of the device, safety alarms (such as over-temperature protection), and operation mode switching. The voice reminder aims to improve the controllability and safety of the device while enhancing the user experience. The reminder content also supports customization to increase user affinity. Through the voice interaction design, the embodiment of the present invention not only simplifies the operation process but also significantly enhances the interaction between the user and the intelligent hair dryer, bringing a convenient, intelligent, and user-friendly use experience.

[0131] Optionally, when the intelligent hair dryer is powered on, it defaults to the normal mode. The intelligent hair dryer uses intelligent temperature control technology to stably control the hair temperature at 55°C to 58°C, providing an efficient and comfortable hair drying experience. In addition, users can perform combined operations of the setting button and the plus / minus gear buttons to customize the temperature standard and the wind speed according to their personal preferences within the safety standards of the device. The intelligent storage function built into the intelligent hair dryer can automatically record the personalized parameters set by the user. Without repeated adjustment, the settings saved last time will be applied by default when the device is powered on next time, greatly improving the use convenience. When the system detects special situations, such as when the image captured by the camera recognizes that the head shape is a child, the hair volume is sparse, the scalp is allergic, or when the distance detection unit 60 detects that the distance between the air outlet and the hair is less than 10 cm, the intelligent hair dryer will automatically switch to the protection mode. In the protection mode, the temperature control system adjusts the temperature range to 47°C to 50°C to avoid discomfort or damage caused by high temperature.
