[0002] Hair dryers are electrical appliances mainly used for hair drying and shaping. Traditional hair dryers only use mechanical devices to control wind speed and heating wire wattage, and do not detect and feedback the temperature of the air flow and the temperature of the hair. In recent years, domestic and foreign hair dryer manufacturers have proposed various products that detect the air flow sent by the hair dryer or the user's hair, and then use empirical values ​​to estimate the constant temperature control of the user's hair temperature, or further control the heating wire wattage based on the hair temperature feedback, which has become a competitive point for high-end hair dryers. At present, there is a problem that during the use of the hair dryer, the distance between the hair dryer and the user's hair or skin affects the heating wire wattage, and the temperature sensed by the surface heat radiation of the user's hair and skin to the thermopile temperature sensor cannot be used to control the heating wire wattage.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0047] Figure 2 is a control state diagram of an intelligent hair dryer provided by an embodiment of the present invention;

[0048] Figure 3 It is a structural schematic diagram of a control device for an intelligent hair dryer provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] like Figure 1 As shown, Figure 1 1 is a flow chart of a control method of a smart hair dryer provided by an embodiment of the present invention. The control method of the smart hair dryer specifically comprises the following steps:

[0051] 101. When the smart hair dryer is working, it collects the temperature data of the user's hair.

[0052] In an embodiment of the present invention, the above-mentioned intelligent hair dryer includes a temperature sensor, a heating wire, an analog-to-digital converter and a control component, wherein the temperature sensor senses the hair temperature in a non-contact manner, the analog-to-digital converter, the temperature sensor and the control component are electrically connected, the analog-to-digital converter converts the temperature analog signal of the temperature sensor into a digital signal and outputs it to the control component, and the control component is used to execute the control method of the intelligent hair dryer.

[0053] The temperature sensor can be a thermoelectric pusher. The thermoelectric pusher estimates the blackbody radiation temperature of the distant object surface based on the thermal radiation wattage within the thermopile viewing angle FOV through an algorithm. Therefore, the measured temperature is approximately the average temperature within this FOV. The FOV of the thermopile is often 80° to 90°, which corresponds to a large area at a distance of 30cm to 60cm. Moreover, the FOV receiving range may not only include hair, but also other parts other than hair and space with only air but no human body. Therefore, a lens or a group of lenses is added in front of the thermopile so that the FOV of the temperature sensor is focused to a small range at a certain distance through the lens, and the surface blackbody radiation power is received therein. The FOV of the thermopile is called FOV1, and the FOV after the lens is called FOV2. For example, a lens is used so that FOV2 can obtain the surface thermal radiation of objects within a circular range of 3cm in diameter at a distance of 30cm.

[0054] The above analog-to-digital converter can be understood as a device that converts an analog signal into a digital signal.

[0055] The above-mentioned smart hair dryer includes an AI smart constant temperature mode. The AI ​​smart constant temperature mode can be understood as an intelligent constant temperature mode that uses artificial intelligence technology to realize intelligent control of wind temperature, can dry hair quickly, and protect the health of hair and scalp.

[0056] Furthermore, if the AI ​​intelligent constant temperature mode is not activated, the heating wire will heat the airflow at a fixed wattage; if the AI ​​intelligent constant temperature mode is activated, the wind temperature will be intelligently controlled to achieve a balance between fast hair drying and scalp comfort, while protecting the health of the hair and scalp.

[0057] It should be noted that the present invention uses an analog-to-digital converter with a sampling frequency of 100 Hz. Under the conditions of the hair dryer swing speed and the thermopile response speed, 100 temperature data can be collected per second, and each temperature data is numbered from 1 to 100 in the order of collection for subsequent temperature data processing.

[0058] 102. Classify the temperature data and determine the temperature data in each temperature classification.

[0059] In the embodiment of the present invention, the above classification process can be understood as a process of grouping the collected hair temperature data according to certain rules.

[0060] The above temperature classification includes Class I temperature, Class II temperature, Class III temperature, Class IV temperature, and Class V temperature. Class I temperature can be understood as 30℃ to 40℃, Class II temperature can be understood as 40℃ to 45℃, Class III temperature can be understood as 45℃ to 50℃, Class IV temperature can be understood as 50℃ to 55℃, and Class V temperature can be understood as above 55℃.

[0061] Generally speaking, people can hold a cup below 55℃ for a short time, but will let go immediately if it exceeds 55℃. For a 50℃ cup, although people can hold it without letting go immediately, they will feel extremely hot. If it is a 45℃ cup, most people can hold it for a long time without feeling too hot. However, skin exposed to 40℃ for a long time will cause low-temperature burns or even blisters. Hair exposed to more than 45℃ for a long time will damage the hair quality. Therefore, the temperature classification is divided into five temperature categories, each category corresponds to a temperature range, which can better understand the temperature status of the hair.

[0062] Furthermore, the 100 temperature data can be classified and processed according to the temperature classification to obtain the number of temperature data in each temperature classification, for example, there are 35 temperatures in Class 1, 40 temperatures in Class 2, 20 temperatures in Class 3, 5 temperatures in Class 4, and 0 temperatures in Class 5; there are 55 temperatures in Class 1, 35 temperatures in Class 2, 10 temperatures in Class 3, 0 temperatures in Class 4, and 0 temperatures in Class 5; there are 20 temperatures in Class 1, 40 temperatures in Class 2, 40 temperatures in Class 3, 10 temperatures in Class 4, and 10 temperatures in Class 5, etc.

[0063] The temperature data in each of the above temperature categories include the number of hair temperatures in the first temperature category, the number of hair temperatures in the second temperature category, the number of hair temperatures in the third temperature category, the number of hair temperatures in the fourth temperature category, and the number of hair temperatures in the fifth temperature category.

[0064] It should be noted that for hair below 30℃, there is no need to control the temperature, so the temperature data below 30℃ is marked as invalid, and the temperature data below 30℃ is ignored in the analysis and judgment. For the human body, the temperature below 30℃ is generally considered to be relatively suitable.

[0065] 103. Analyze and judge the temperature data in different temperature categories to determine the risk status of the smart hair dryer to the user.

[0066] In the embodiment of the present invention, the temperature data in the above-mentioned different temperature categories include the number of hair temperatures in temperature category 1, the number of hair temperatures in temperature category 2, the number of hair temperatures in temperature category 3, the number of hair temperatures in temperature category 4, and the number of hair temperatures in temperature category 5.

[0067] The risk status of the smart hair dryer to the user can be determined based on the number of hair temperatures of Class 1 temperature, the number of hair temperatures of Class 2 temperature, the number of hair temperatures of Class 3 temperature, the number of hair temperatures of Class 4 temperature, and the number of hair temperatures of Class 5 temperature.

[0068] The above-mentioned risk states include severe pain state, high-risk state, medium-risk state, low-risk state, etc. The above-mentioned severe pain state can be understood as a state that makes people feel high heat and stinging pain. The severe pain state includes the number of three types of temperatures, the number of four types of temperatures, and the number of five types of temperatures; the above-mentioned high-risk state can be understood as a state that is highly dangerous to the human body. Although it will not make people feel high-temperature burning, it will cause low-temperature burns and even blisters. The high-risk state includes the number of five types of temperatures = 0, the number of four types of temperatures = 0, and the number of three types of temperatures > 50; the above-mentioned medium-risk state can be understood as a state of moderate danger to the human body. The medium-risk state includes the number of five types of temperatures = 0, the number of four types of temperatures = 0, the number of three types of temperatures = 0, and 20 < the number of two types of temperatures < 50; the above-mentioned low-risk state can be understood as a state of low danger to the human body. The low-risk state includes the number of five types of temperatures = 0, the number of four types of temperatures = 0, the number of three types of temperatures = 0, the number of one type of temperature, and the number of two types of temperatures < 20.

[0069] 104. Based on the risk status, the smart hair dryer is controlled through a preset control strategy.

[0070] In the embodiment of the present invention, the above-mentioned preset control strategy is a pre-set control strategy, which specifically includes:

[0071] A. Severe pain state

[0072] (1) If the number of five temperature categories is > 0, reduce the heating wire wattage by 30%;

[0073] (2) The number of five temperature categories = 0, the number of four temperature categories > 0, and the heating wire wattage is reduced by 20%;

[0074] (3) The number of five temperature categories = 0, the number of four temperature categories = 0, the number of three temperature categories > 0, and the wattage of the heating wire is reduced by 15%.

[0075] B. High-risk status

[0076] (1) Stable mode: the number of five temperature categories = 0, the number of four temperature categories = 0, the number of three temperature categories = 0, the number of two temperature categories > 50, and the heating wire wattage is reduced by 10%;

[0077] (2) Slow swing mode: 5th temperature quantity = 0, 4th temperature quantity = 0, 3rd temperature quantity = 0, 2nd temperature quantity > 50, heating wire wattage reduced by 5%;

[0078] (3) Fast swing mode: Five-type temperature quantity = 0, four-type temperature quantity = 0, three-type temperature quantity = 0, two-type temperature quantity> 50, maintain the heating wire wattage.

[0079] C. Medium risk status

[0080] (1) Stable mode: the number of five temperature categories = 0, the number of four temperature categories = 0, the number of three temperature categories = 0, 20 < the number of two temperature categories < 50, the heating wire wattage is reduced by 5%;

[0081] (2) Swing mode: 5th temperature quantity = 0, 4th temperature quantity = 0, 3rd temperature quantity = 0, 20<2nd temperature quantity<50, keep heating wire wattage:

[0082] D. Low risk status

[0083] (1) Stable mode: 5-type temperature quantity = 0, 4-type temperature quantity = 0, 3-type temperature quantity = 0, 2-type temperature quantity < 20, 1-type temperature quantity, heating wire wattage increased by 10%;

[0084] (2) Swing mode: 5th temperature quantity = 0, 4th temperature quantity = 0, 3rd temperature quantity = 0, 2nd temperature quantity < 20, heating wire wattage increases by 20%.

[0085] The above-mentioned risk states include severe pain state, high-risk state, medium-risk state, low-risk state, etc.

[0086] Furthermore, when the risk state is a severe pain state, when the hair or skin temperature is higher than 45°C, it will cause a high temperature burning sensation, and if the hair is in a state higher than 45°C for a long time, it will damage the hair quality, so the wattage of the heating wire needs to be reduced; when the risk state is a high risk state, when the hair or skin temperature is higher than 40°C, although it will not cause a high temperature burning sensation, the skin will still cause low temperature burns or even blisters if it is higher than 40°C for a long time, so the wattage of the heating wire needs to be reduced; when the risk state is a medium risk state, the hot zone is fixed within a small area, and the hair and skin temperature is higher than 40°C for more than one-fifth of the time, so the wattage of the heating wire needs to be reduced; when the risk state is a low risk state, the purpose of using a hair dryer to blow dry wet hair is to use a large amount of hot air to dry wet hair, so the wattage of the heating wire needs to be increased to speed up the drying of the hair.

[0087] In the embodiment of the present invention, the present invention can measure the surface temperature of an object obtained by measuring the thermal radiation power of a black body in a narrow FOV area at the far end with a non-contact temperature sensor without detecting the distance between the hair and the hair dryer, and without detecting the humidity of the hair. The temperature data is used to control the heating wire of the hair dryer, so as to protect the user from severe pain caused by high heat, and quickly cool down the hair. In the absence of severe high-temperature burning pain, the temperature of the hair is evaluated, and the wattage of the heating wire is adjusted according to the risk level of possible injury, so as to protect the user from injury, and allow the user to increase the hot air temperature as stably as possible without being injured. When the user slowly swings the hair dryer, the wattage of the heating wire of the hair dryer is stably or slowly adjusted. When the user swings the hair dryer quickly, the wattage of the heating wire of the hair dryer is increased more quickly, so that the user can get a good user experience.

[0088] In an embodiment of the present invention, when the smart hair dryer is working, the temperature data of the user's hair is collected; the temperature data is classified and processed to determine the temperature data in each temperature classification; the temperature data in the different temperature classifications are analyzed and judged to determine the risk status of the smart hair dryer to the user; based on the risk status, the smart hair dryer is controlled by a preset control strategy. The present invention can solve the problem that the existing hair dryer is affected by the distance between the hair dryer and the user's hair or skin during use, and the heating wire wattage cannot be controlled by the temperature sensed by the surface heat radiation of the user's hair and skin to the thermopile temperature sensor.

[0089] It should be noted that the control method of the smart hair dryer provided in the embodiment of the present invention can be applied to computers, edge terminals, servers, cloud platforms and other devices that can perform the control method of the smart hair dryer.

[0090] Optionally, in the step of classifying the temperature data and determining the temperature data in each temperature classification, the temperature data can be preprocessed to obtain preprocessed temperature data, which is valid temperature data; the preprocessed temperature data is classified to determine the temperature data in each temperature classification.

[0091] In the embodiment of the present invention, the data preprocessing can be understood as a process of processing the original data, specifically, it can be a process of marking the hair temperature data below 30° C. as invalid and retaining the hair temperature data above 30° C. For the human body, the temperature below 30° C. is generally considered to be a relatively suitable temperature.

[0092] The above classification process can be understood as a process of grouping the collected hair temperature data according to certain rules, and specifically can be a process of grouping the collected hair temperature data according to temperature classification rules.

Class I temperature can be understood as 30℃ to 40℃, Class II temperature can be understood as 40℃ to 45℃, Class III temperature can be understood as 45℃ to 50℃, Class IV temperature can be understood as 50℃ to 55℃, and Class V temperature can be understood as above 55℃.

[0094] Furthermore, the preprocessed temperature data is classified and processed to determine the temperature data in each temperature classification.

[0095] It should be noted that for hair temperature data below 30°C, there is no need to control the temperature to be lowered, so the temperature data below 30°C is marked as invalid first, and the temperature data below 30°C is ignored in the analysis and judgment.

[0096] Optionally, the temperature classification includes Class I temperature, Class II temperature, Class III temperature, Class IV temperature, and Class V temperature, wherein Class I temperature < Class II temperature < Class III temperature < Class IV temperature < Class V temperature. In the step of analyzing and judging the temperature data in different temperature classifications to determine the risk status of the smart hair dryer to the user, the temperature data of Class I temperature can be subjected to a first analysis and judgment process to determine the number of Class I temperatures; the temperature data of Class II temperature can be subjected to a second analysis and judgment process to determine the number of Class II temperatures; the temperature data of Class III temperature can be subjected to a third analysis and judgment process to determine the number of Class III temperatures; the temperature data of Class IV temperature can be subjected to a fourth analysis and judgment process to determine the number of Class IV temperatures; the temperature data of Class V temperature can be subjected to a fifth analysis and judgment process to determine the number of Class V temperatures; based on the number of Class I temperature, the number of Class II temperature, the number of Class III temperature, the number of Class IV temperature, and the number of Class V temperature, the risk status of the smart hair dryer to the user is determined.

[0097] In an embodiment of the present invention, the above-mentioned Class 1 temperature may be 30°C to 40°C, Class 2 temperature may be 40°C to 45°C, Class 3 temperature may be 45°C to 50°C, Class 4 temperature may be 50°C to 55°C, and Class 5 temperature may be above 55°C.

The severe pain state includes the number of three types of temperatures, the number of four types of temperatures, and the number of five types of temperatures; the above-mentioned high-risk state can be understood as a state that is highly dangerous to the human body. Although it will not make people feel high-temperature burning, it will cause low-temperature burns and even blisters. The high-risk state includes the number of five types of temperatures = 0, the number of four types of temperatures = 0, and the number of three types of temperatures > 50; the above-mentioned medium-risk state can be understood as a state of moderate danger to the human body.

[0099] It should be noted that the risk status of the smart hair dryer to the user can be determined based on the number of first-category temperature, the number of second-category temperature, the number of third-category temperature, the number of fourth-category temperature, and the number of fifth-category temperature.

[0100] Optionally, in the step of controlling the smart hair dryer through a preset control strategy based on the risk state, if the risk state is a first risk state, the wattage of the heating wire of the smart hair dryer is controlled to be reduced by the preset control strategy; if the risk state is a second risk state, the second wattage of the second heating wire of the smart hair dryer is controlled to be reduced by the preset control strategy; if the risk state is a third risk state, the wattage of the heating wire of the smart hair dryer is controlled to be reduced by the preset control strategy; if the risk state is a fourth risk state, the wattage of the heating wire of the smart hair dryer is controlled to be increased by the preset control strategy.

[0101] In the embodiment of the present invention, the first risk state can be understood as a severe pain state, a state in which a person feels a high temperature and stinging sensation.

[0105] The above preset control strategy is a pre-set control strategy, specifically including:

[0106] A. Severe pain state

[0108] (2) The number of five temperature categories = 0, the number of four temperature categories > 0, and the heating wire wattage is reduced by 20%;

[0109] (3) The number of five temperature categories = 0, the number of four temperature categories = 0, the number of three temperature categories > 0, and the heating wire wattage is reduced by 15%.

[0110] B. High-risk status

[0111] (1) Stable mode: the number of five temperature categories = 0, the number of four temperature categories = 0, the number of three temperature categories = 0, the number of two temperature categories > 50, and the heating wire wattage is reduced by 10%;

[0112] (2) Slow swing mode: 5th temperature quantity = 0, 4th temperature quantity = 0, 3rd temperature quantity = 0, 2nd temperature quantity > 50, heating wire wattage reduced by 5%;

[0113] (3) Fast swing mode: Five-type temperature quantity = 0, four-type temperature quantity = 0, three-type temperature quantity = 0, two-type temperature quantity > 50, maintain the heating wire wattage.

[0114] C. Medium risk status

[0115] (1) Stable mode: the number of five temperature categories = 0, the number of four temperature categories = 0, the number of three temperature categories = 0, 20 < the number of two temperature categories < 50, the heating wire wattage is reduced by 5%;

[0116] (2) Swing mode: 5th temperature quantity = 0, 4th temperature quantity = 0, 3rd temperature quantity = 0, 20<2nd temperature quantity<50, keep heating wire wattage:

[0117] D. Low risk status

[0118] (1) Stable mode: 5-type temperature quantity = 0, 4-type temperature quantity = 0, 3-type temperature quantity = 0, 2-type temperature quantity < 20, 1-type temperature quantity, heating wire wattage increased by 10%;

[0119] (2) Swing mode: 5th temperature quantity = 0, 4th temperature quantity = 0, 3rd temperature quantity = 0, 2nd temperature quantity < 20, heating wire wattage increases by 20%.

[0120] Furthermore, if the risk state is a severe pain state, the wattage of the heating wire of the smart hair dryer is first reduced through a preset control strategy. This is because when the temperature of the hair or skin is higher than 45°C, it will cause a high temperature burning sensation, and if the hair is in a state higher than 45°C for a long time, it will damage the hair quality, and the wattage of the heating wire must be reduced immediately.

[0121] If the risk status is high-risk, the wattage of the heating wire of the smart hair dryer is reduced for the second time through the preset control strategy. This is because when the hair or skin temperature is higher than 40°C, although it will not cause a high-temperature burning sensation, if the skin is higher than 40°C for a long time, it will still cause low-temperature burns or even blisters. Therefore, when the temperature measured by the thermopile exceeds 40°C for more than half of the time, the wattage of the heating wire still needs to be reduced.

[0122] If the risk status is a medium risk status, the wattage of the heating wire of the smart hair dryer is controlled to be reduced for the third time through a preset control strategy, because the temperature of the hair and skin is above 40°C for more than one-fifth of the time, and the wattage of the heating wire is controlled to decrease slowly.

[0123] If the risk state is a low risk state, the wattage of the heating wire of the smart hair dryer is increased and controlled through a preset control strategy. In the low risk state, the swing mode of the smart hair dryer is first determined. If the swing mode is a stable mode, the number of five types of temperatures = 0, the number of four types of temperatures = 0, the number of three types of temperatures = 0, the number of two types of temperatures <20, and the number of one type of temperature, then the wattage of the heating wire of the smart hair dryer is increased by 10%; because the purpose of using a hair dryer to blow hair is to use a large amount of hot air to dry wet hair, so in the stable mode, the wattage of the heating wire is increased by 10% to speed up the drying of hair, and only less than 20% of the time the temperature of the hair and skin falls between 40°C and 45°C, and the other 80% of the time the temperature of the hot zone is below 40°C, which is a comfortable feeling for the user. Even if the user does not feel the hot air exceeding 40°C, the user will feel that the hair dryer has not achieved the effect of drying the hair, so the wattage of the heating wire must be slightly increased. If the swing mode is the swing mode, the number of five temperature categories = 0, the number of four temperature categories = 0, the number of three temperature categories = 0, and the number of two temperature categories <20, then the wattage of the heating wire of the smart hair dryer is increased by 20%; because the purpose of using a hair dryer to blow hair is to use a large amount of hot air to dry wet hair, and the user constantly swings the hair dryer, which reduces the chance of damaging the hair or skin, and the user constantly swings the hair dryer, indicating that the user wants to dry the hair quickly, so the wattage of the heating wire is increased by 20%, and this process is continued. When the temperature enters the medium-risk or high-risk temperature range, the wattage of the heating wire can be reduced again.

[0124] The swing mode of the smart hair dryer can be understood as the working swing state of the hair dryer, and the blowing method is adjusted according to the needs of the user. The swing state includes a stable mode and a swing mode. The above-mentioned stable mode can be understood as the heat zone being stable within a small area. The above-mentioned swing mode can be understood as a swing mode in which the swing speed and amplitude of the air outlet of the hair dryer change. Specifically, 100 temperature data per second can be collected, and each temperature data is numbered from 1 to 100 in the order of collection; then, every 10 continuous changes are set as a time zone, and each second is divided into 10 time zones; then, the average value of the 10 temperature data in each time zone is calculated. If the average value of the temperature data in the 10 time zones is within 5°C, it is a stable mode. If the average value of the temperature data in the 10 time zones exceeds 5°C, it is a swing mode.

[0125] Optionally, in the step of performing a first reduction control on the wattage of the heating wire of the smart hair dryer through a preset control strategy if the risk state is the first risk state, if the risk state is the first risk state, when the number of five temperature categories is greater than 0, the wattage of the heating wire of the smart hair dryer is reduced by 30% through the preset control strategy; if the risk state is the first risk state, when the number of five temperature categories is equal to 0 and the number of four temperature categories is greater than 0, the wattage of the heating wire of the smart hair dryer is reduced by 20% through the preset control strategy; if the risk state is the first risk state, when the number of five temperature categories is equal to 0, the number of four temperature categories is equal to 0 and the number of three temperature categories is greater than 0, the wattage of the heating wire of the smart hair dryer is reduced by 15% through the preset control strategy.

[0126] In an embodiment of the present invention, the above-mentioned first risk state can be understood as a severe pain state, a state that makes people feel high heat and tingling. The severe pain state is that the number of three types of temperatures is >0, the number of four types of temperatures is =0, the number of five types of temperatures is =0, the number of four types of temperatures is >0, the number of five types of temperatures is =0, and the number of five types of temperatures is >0.

[0127] If the number of five types of temperatures is > 0, immediately reduce the wattage of the heating wire of the smart hair dryer by 30%. Because when the temperature of hair or skin is higher than 55°C, it will cause a high temperature stinging sensation and quickly damage the hair or skin, so the wattage of the heating wire must be reduced immediately. If there is still a high risk of five types of temperatures in the next second, it will be reduced by another 30%. A 30% reduction twice equals 0.7*0.7=49%, and the wattage of the heating wire becomes half of the original, and so on. Therefore, under the five temperature conditions, the heating wire will stop heating quickly, and the airflow blown by the hair dryer will become cold air.

[0128] If the number of five temperature categories = 0, and the number of four temperature categories > 0, the wattage of the heating wire of the smart hair dryer will be reduced by 20%. Because when the hair or skin temperature is higher than 50, it will still cause a high heat stinging sensation, but the speed of damage to the skin and hair will not be as fast as the above situation of over 55°C. In this situation, the wattage of the heating wire must be reduced immediately, but the reduction rate is 20%. If it continues to remain in this state in the next second, the wattage of the heating wire will continue to decrease by 20%. If it decreases by 20% twice in two seconds, it is 0.8*0.8=64%. The hot air temperature decreases at a fairly fast rate.

[0129] If the number of five temperature types is equal to 0, the number of four temperature types is equal to 0, and the number of three temperature types is greater than 0, the wattage of the heating wire of the smart hair dryer will be reduced by 15%. Because when the temperature of hair or skin is higher than 45℃, it will still make people feel hot and burning, and if the hair is kept above 45℃ for a long time, it will still damage the hair quality. However, because the temperature of hair or skin in this state is lower than 50℃, it is not necessary to remove the heat source immediately. Therefore, the wattage of the heating wire is reduced at a medium speed. If it continues to remain in this state in the next second, the wattage of the heating wire will continue to decrease by 15%, and the hot air temperature will decrease at this medium and stable speed until the hair or skin temperature is no longer higher than 45℃.

[0130] Optionally, if the risk state is the second risk state, in the step of performing a second reduction control on the wattage of the second heating wire of the smart hair dryer through a preset control strategy, if the risk state is the second risk state, the swing mode of the smart hair dryer is determined; if the swing mode is the stable mode, the wattage of the heating wire of the smart hair dryer is reduced by 10% through the preset control strategy; if the swing mode is the slow swing mode, the wattage of the heating wire of the smart hair dryer is reduced by 5% through the preset control strategy; if the swing mode is the fast swing mode, the wattage of the heating wire of the smart hair dryer is maintained.

[0131] In the embodiment of the present invention, the swing mode of the above-mentioned smart hair dryer can be understood as the working swing state of the hair dryer, and the blowing mode is adjusted according to the needs of the user. The swing state includes a stable mode and a swing mode, and the swing mode includes a slow swing mode and a fast swing mode.

[0132] The above stability mode can be understood as the hot zone being stable within a small area.

[0133] The above-mentioned swinging mode can be understood as a swinging mode in which the swinging speed and amplitude of the air outlet of the hair dryer change.

[0134] The above-mentioned slow oscillation mode can be understood as a mode in which the oscillation speed of the hair dryer is very slow.

[0135] The above-mentioned fast swing mode can be understood as a mode in which the hair dryer swings at a very fast speed.

[0136] Specifically, 100 temperature data are collected per second, and each temperature data is numbered from 1 to 100 in the order of collection; then, every 10 continuous changes are set as a time zone, and each second is divided into 10 time zones; then, the average value of the 10 temperature data in each time zone is calculated. If the average value of the temperature data in the 10 time zones is within 5°C, it is a stable mode. If the average value of the temperature data in the 10 time zones exceeds 5°C, it is a swing mode. In the stable mode, the average value of the temperature data in each time zone is within 5 degrees, indicating that the hot zone caused by the hair dryer is stable within a certain area.

[0137] In the swing mode, the temperature data in a single time zone is continuously rising or continuously falling, and the time zones where the temperature data are continuously rising or falling are marked as continuously changing time zones.

[0138] Furthermore, the time zone marked as continuously changing is selected to determine whether it is a fast swing mode: if the highest and lowest temperatures in the 10 continuously changing temperature data in the same time zone exceed 5°C, it is a fast swing mode; if the highest and lowest temperatures in the 10 continuously changing temperature data in the same time zone do not exceed 5°C, it is a slow swing mode. In the fast swing mode, because the 10 temperature data collected in one time zone (0.1 second) are continuously changing, it means that the user not only does not stop at a fixed position, but also swings the hair dryer back and forth quickly at a stable speed.

[0139] The second risk state can be understood as a high-risk state, a state that is highly dangerous to the human body. Although it will not cause a high-temperature burning sensation, it will cause low-temperature burns and even blisters. The high-risk state is when the number of four-category temperatures = 0, the number of five-category temperatures = 0, and the number of three-category temperatures > 50.

[0140] If the swing mode of the smart hair dryer is in stable mode, the number of five types of temperatures = 0, the number of four types of temperatures = 0, and the number of three types of temperatures > 50, then the wattage of the smart hair dryer heating wire will be reduced by 10%. Because, when the temperature of hair or skin is higher than 40℃, although people will not feel high temperature burning, the skin will still cause low temperature burns or even blisters if it is higher than 40℃ for a long time. Therefore, when the temperature measured by the thermopile exceeds 40℃ for more than half of the time, the actual maximum temperature of the hair and skin in a small local area is bound to be higher than the average temperature in the thermopile FOV2. The stable mode means that the hot zone is stable within a small area, so the wattage of the heating wire is still reduced by 10%. If it continues to remain in this state in the next second, the wattage of the heating wire will continue to decrease by 10%, and the hot air temperature will decrease slowly until the temperature of the hair or skin measured by the thermopile is no longer higher than 40℃ for more than half of the time per second.

[0141] If the swing mode of the smart hair dryer is the slow swing mode, the number of five types of temperatures = 0, the number of four types of temperatures = 0, and the number of three types of temperatures > 50, then the wattage of the smart hair dryer heating wire is reduced by 5%. Because the user is swinging the hair dryer all the time, the hot zone above 40°C does not stay in the same place continuously, and the user is swinging the hair dryer and can adjust the position of the hot zone according to the temperature sense of the human body, so the hot zone below 45°C will not cause damage to the hair or skin. Therefore, it is only necessary to reduce the wattage of the heating wire very slowly until half of the hair and skin temperature data measured by the thermopile per second falls below 40°C. At that time, less than half of the hair and skin temperature data measured by the thermopile per second falls between 40°C and 45°C, and the hot zone is constantly moving due to the swinging of the hair dryer, so it will not cause harm to the human body.

[0142] If the swing mode of the smart hair dryer is the fast swing mode, the number of five-category temperature = 0, the number of four-category temperature = 0, and the number of three-category temperature > 50, then the wattage of the smart hair dryer heating wire is maintained. Because the user has been swinging the hair dryer quickly, the hot zone above 40°C and below 45°C does not stay in the same place continuously, which will not cause damage to the hair or skin. In addition, the user is swinging the hair dryer quickly and steadily, which means that the user wants to dry the hair quickly, so there is no need to adjust the wattage of the heating wire.

[0143] Optionally, in the step of performing a third reduction control on the wattage of the heating wire of the smart hair dryer through a preset control strategy if the risk state is the third risk state, if the risk state is the third risk state, the swing mode of the smart hair dryer is determined; if the swing mode is the stable mode, the wattage of the heating wire of the smart hair dryer is reduced by 5% through the preset control strategy; if the swing mode is the swing mode, the wattage of the heating wire of the smart hair dryer is maintained.

[0144] In the embodiment of the present invention, the third risk state can be understood as a medium risk state, a state of moderate risk of harming the human body. The medium risk state is that the number of five temperature categories = 0, the number of four temperature categories = 0, the number of three temperature categories = 0, and 20 < the number of two temperature categories < 50.

[0145] If the swing mode of the smart hair dryer is in stable mode, the number of five-category temperature = 0, the number of four-category temperature = 0, the number of three-category temperature = 0, 20 < the number of two-category temperature < 50, then the wattage of the smart hair dryer heating wire is reduced by 5%. In stable mode, the hot zone is fixed within a small area, and the hair and skin temperature is higher than 40°C for more than one-fifth of the time, so the heating wire wattage is controlled to decrease slowly, and this process is repeated until the number of Class B temperature data between 40°C and 45°C per second is less than 20.

[0146] If the swing mode of the smart hair dryer is the swing mode, the number of five-category temperature = 0, the number of four-category temperature = 0, the number of three-category temperature = 0, 20 < the number of two-category temperature < 50, then the wattage of the smart hair dryer heating wire is maintained. Because the hair dryer is in a swinging state, less than half of the time per second is above 40°C and below 45°C, and the hot zone above 40°C does not stop at the same place continuously. Because the user is swinging the hair dryer, the position of the hot zone can be adjusted according to the temperature sensed by the human body, so it will not cause damage to the hair or skin. In addition, the user swings the hair dryer to indicate that he wants to dry his hair quickly, so the wattage of the heating wire is not changed.

[0147] like Figure 2 As shown, Figure 2 This is a control state diagram of a smart hair dryer provided by an embodiment of the present invention. Specifically, the control states of the smart hair dryer include 100, sampling for 1 second, 110, analysis and judgment, 120, severe pain state control, 130, high risk state control, 140, medium risk state control, and 150, low risk state control.

[0148] In an embodiment of the present invention, the above-mentioned smart hair dryer includes an AI smart constant temperature mode. The AI ​​smart constant temperature mode can be understood as an intelligent constant temperature mode that uses artificial intelligence technology to achieve intelligent control of wind temperature, can dry hair quickly, and protect the health of hair and scalp.

[0149] The above sampling for 1 second can be understood as sampling 100 temperature data per second for 1 second; after the collection is completed, enter 120 for analysis and judgment.

[0150] The above 110 analysis and judgment can be understood as classifying and statistically analyzing the 100 temperature data and performing time domain analysis to obtain the classification results of the 100 temperature data and enter different risk states for control.

[0151] The above classification statistics can be understood as the process of classifying and counting temperature data according to temperature rules.

[0152] The present invention does not need to control the temperature of hair below 30°C, so the data below 30°C is marked as invalid, and the temperature data below 30°C is ignored in the analysis and judgment; the valid data is divided into five categories: A. 30°C to 40°C, B. 40°C to 45°C, C. 45°C to 50°C, D. 50°C to 55°C, and E. above 55°C. The above valid data is the temperature data above 30°C.

[0153] Furthermore, the number of 100 temperature data in each temperature classification is calculated, for example, 35 in Class A, 40 in Class B, 20 in Class C, 5 in Class D, and 0 in Class E.

[0154] The above time domain analysis can be understood as the process of analyzing temperature data in time.

[0155] The present invention sets every 10 consecutive numbers as a time zone, and divides each second into 10 time zones; then, calculates the average value of 10 temperature data in each time zone. If the average value of the temperature data in the 10 time zones is within 5°C, it is a stable mode. The stable mode is that the average value of the temperature data in each time zone is within 5 degrees, indicating that the hot zone caused by the hair dryer is stable within a certain area. If the average value of temperature data in 10 time zones exceeds 5°C, it is in swing mode; in swing mode, the temperature data in a single time zone is continuously rising or continuously falling, and the time zones where these temperature data meet the continuous rising or falling requirements are marked as continuously changing time zones; select the time zones marked as continuously changing time zones to judge the fast swing mode and the slow swing mode. If the highest and lowest temperatures in the 10 continuously changing temperature data in the same zone exceed 5 degrees, it is in fast swing mode, because the 10 temperature data collected within 0.1 seconds are continuously changing, indicating that the user not only did not stop at a fixed position, but also swung the hair dryer back and forth quickly at a stable speed; if the highest and lowest temperatures in the 10 continuously changing temperature data in the same zone do not exceed 5 degrees, it is in slow swing mode.

[0156] Optionally, if the quantity results in categories C, D, and E are greater than 0, enter 120 severe pain state control.

[0157] The above-mentioned severe pain state can be understood as a state that makes people feel high fever and tingling.

[0158] Furthermore, if the number of Class E>0, the wattage of the heating wire is immediately reduced by 30%, because when the temperature of hair or skin is higher than 55℃, it will cause a high heat and stinging sensation, and quickly damage the hair or skin, so the wattage of the heating wire must be reduced immediately. If there is still a high risk of Class E, it will be reduced by another 30%. The two reductions of 30% are equal to 0.7*0.7=49%, and the wattage of the heating wire becomes half of the original. By analogy, in the Class E state, the heating wire will stop heating quickly, and the airflow blown by the hair dryer will become cold air; if the number of Class E=0, the number of Class D>0, the wattage of the heating wire will be reduced by 20%, because when the temperature of hair or skin is higher than 50℃, it will still cause a high heat and stinging sensation, but the speed of damage to the skin and hair will not be as fast as the above situation of exceeding 55℃. In this situation, the wattage of the heating wire must still be reduced immediately, but the reduction rate is 20%. If it continues to remain in this state in the next second, the wattage of the heating wire will continue to decrease by 20%, and the two A continuous decrease of 20% twice in one second is 0.8*0.8=64%, and the hot air temperature decreases at a very fast speed; if the number of class E = 0, the number of class D = 0, and the number of class C>0, the wattage of the heating wire will be reduced by 15%. Because, when the temperature of hair or skin is higher than 45℃, it will still make people feel hot and burning, and if the hair is kept above 45℃ for a long time, it will still damage the hair. However, because the temperature of hair or skin is lower than 50℃ in this state, it is not necessary to remove the heat source immediately. Therefore, the wattage of the heating wire is reduced at a medium speed. If it continues to remain in this state in the next second, the wattage of the heating wire will continue to decrease by 15%, and the hot air temperature will decrease at this medium and stable speed until the hair or skin temperature is no longer higher than 45℃.

[0159] Optionally, when the number of Class E = 0, the number of Class D = 0, the number of Class C = 0, and the number of Class B > 50, the system enters 130 high-risk state control.

[0160] The above-mentioned high-risk state can be understood as a state that is highly dangerous to the human body. Although it will not cause people to feel high-temperature burning sensation, it will cause low-temperature burns and even blisters.

[0161] Furthermore, in the high-risk state, when the swing mode of the hair dryer is the stable mode, the wattage of the heating wire is reduced by 10%. Because when the temperature of the hair or skin is higher than 40°C, although it will not cause a feeling of high-temperature burning, long-term skin temperature above 40°C will still cause low-temperature burns and even blisters. Therefore, when the temperature measured by the thermopile exceeds 40°C for more than half of the time, the highest temperature of the real hair and skin in a small local area is bound to be higher than the average temperature within the thermopile FOV2. And the stable mode means that the hot area is stable within a small area range. Therefore, the wattage of the heating wire is still reduced by 10%. If it continues to maintain this state in the next second, the wattage of the heating wire will continue to be reduced by 10%, and the hot air temperature will drop at a slow speed until the temperature of the hair or skin measured by the thermopile does not exceed 40°C for more than half of the time per second; when the swing mode of the hair dryer is the slow swing mode, the wattage of the heating wire is reduced by 5%. Because the user has been swinging the hair dryer, the hot area above 40°C does not stay continuously in the same place. And the user is swinging the hair dryer, and can adjust the position of the hot area according to the body's temperature feeling. Therefore, the hot area below 45°C will not cause damage to the hair quality or skin. So only need to very slowly reduce the wattage of the heating wire until half of the temperature data of the hair and skin measured by the thermopile per second falls below 40°C. By then, less than half of the temperature data of the hair and skin measured by the thermopile per second falls between 40°C and 45°C, and the hot area moves continuously due to the swing of the hair dryer, and will not cause harm to the human body; when the swing mode of the hair dryer is the fast swing mode, keep the wattage of the heating wire. Because the user has been quickly swinging the hair dryer, the hot area above 40°C and below 45°C does not stay continuously in the same place, and will not cause harm to the hair quality or skin. And the user is quickly and steadily swinging the hair dryer, indicating that the user wants to dry the hair quickly. Therefore, there is no need to adjust the wattage of the heating wire.

[0162] Optionally, when the quantity of class E = 0, the quantity of class D = 0, the quantity of class C = 0, and 20 < the quantity of class B < 50, it enters the control of the 140 medium-risk state.

[0163] The above medium-risk state can be understood as a state of moderate danger to the human body.

[0164] Furthermore, in the medium-risk state, when the swing mode of the hair dryer is in the stable mode, the wattage of the heating wire is reduced by 5%, because, in the stable mode, the hot zone is fixed within a small area, and the temperature of the hair and skin is above 40°C for more than one-fifth of the time. Therefore, the wattage of the heating wire is controlled to decrease slowly, and this process is repeated until the number of Class B temperature data of 40°C to 45°C is less than 20 per second; when the swing mode of the hair dryer is in the swing mode, the wattage of the heating wire is maintained, because, when the hair dryer is in the swinging state, it is above 40°C and below 45°C for less than half of the second, and the hot zone above 40°C does not stay in the same place continuously. Because the user is swinging the hair dryer, the position of the hot zone can be adjusted according to the temperature sensed by the human body, so it will not cause damage to the hair or skin, and the user swings the hair dryer to indicate that he wants to dry his hair quickly, so the wattage of the heating wire is not changed.

[0165] Optionally, when the number of Class E = 0, the number of Class D = 0, the number of Class C = 0, the number of Class B < 20, and the number of Class A, it enters 150 low-risk state control.

[0166] The above-mentioned low-risk state can be understood as a state of low risk of harm to the human body.

[0167] Furthermore, in a low-risk state, when the oscillation mode of the hair dryer is in a stable mode, the wattage of the heating wire is increased by 10%, because the purpose of using a hair dryer to blow hair is to use a large amount of hot air to dry wet hair. Therefore, in the stable mode, the wattage of the heating wire is increased by 10% to accelerate the drying of hair, and only less than 20% of the time, the temperature of the hair and skin falls between 40°C and 45°C, and the other 80% of the time, the temperature of the hot zone is below 40°C, which is a comfortable feeling for the user. Even if the user does not feel the hot air exceeding 40°C, the user will feel that the hair dryer has not achieved the effect of drying the hair, so the wattage of the heating wire must be slightly increased; when the oscillation mode of the hair dryer is in an oscillation mode, the wattage of the heating wire is increased by 20%, because the user constantly swings the hair dryer, which further reduces the chance of damage to the hair or skin, and the user constantly swings the hair dryer to indicate that the user wants to dry the hair quickly, so the wattage of the heating wire is increased by 20%, and this process is continued. When the temperature enters the medium-risk or high-risk temperature range, the wattage of the heating wire can be reduced again.

[0168] After completing the 120 severe pain state control, 130 high risk state control, 140 medium risk state control, and 150 low risk state control, and changing the heating wire state, you can go back to 100 samplings for 1 second to collect 100 temperature data, and repeat this cycle for constant temperature mode control.

[0169] After the present invention starts the above-mentioned AI intelligent constant temperature mode, 100 temperature data are collected per second, and each temperature data is numbered from 1 to 100 according to the collected sequence, and its status is analyzed and judged in several stages, and the wattage of the heating wire is controlled and adjusted based on the obtained status results.

[0170] In the embodiment of the present invention, the present invention can measure the surface temperature of an object obtained by measuring the thermal radiation power of a black body in a narrow FOV area at the far end with a non-contact temperature sensor without detecting the distance between the hair and the hair dryer, and without detecting the humidity of the hair.
