[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] In one embodiment, such as Figure 1 As shown, a method for controlling an air outlet device is provided. This embodiment illustrates the application of this method to an air outlet device. It can be understood that an air outlet device refers to a device with an air outlet function. The air outlet device can be any device capable of outlet air, such as a hair dryer, a hand dryer, etc. In this embodiment, the method may include the following steps S102 to S106.

[0032] S102: Obtain the first temperature of the air outlet of the air outlet and the distance between the air outlet and the object being blew when the air outlet is working at a preset setting.

[0033] A preset setting refers to a pre-defined setting on the air outlet device. Air outlet devices operating at different settings have different airflow parameters, which may include parameters related to airflow performance such as airflow temperature and airflow velocity. For example, the settings of an air outlet device may include low temperature, medium temperature, and high temperature settings. Taking airflow velocity as an example, the airflow velocity at the high temperature setting is greater than that at the medium temperature and low temperature settings. In practical applications, the preset setting of the air outlet device can be pre-set, such as a high temperature setting. This application does not limit the preset setting of the air outlet device or the airflow parameters related to the setting; these can be set according to actual application requirements.

[0034] The first temperature refers to the outlet temperature of the air outlet when the air outlet device is operating at a preset setting. The first temperature is a preset value, corresponding to a preset setting. For example, when the air outlet device is operating at a high-temperature setting, the first temperature at the outlet is 80°C; when the air outlet device is operating at a low-temperature setting, the first temperature at the outlet is 60°C. In this embodiment, the first temperature is not limited in any way; it can be any other suitable temperature value such as 50°C, 55°C, or 70°C, and is only provided as an example.

[0035] Distance information is used to indicate the distance between the air outlet device and the object being dried. For example, a distance detection device can be installed near the air outlet of the air outlet device. When the air outlet device is operating at a preset setting, the distance detection device acquires the distance information between the air outlet device and the object being dried. This distance information includes, but is not limited to, the distance between the air outlet device and the object being dried, and the relative position between the object being dried and the air outlet device. The object being dried refers to an object that needs to be dried using the air outlet device, including but not limited to objects with a certain degree of moisture such as hair, clothing, and skin.

[0036] S104: Determine the target distance level corresponding to the distance information.

[0037] The target distance level is used to indicate the distance between the air outlet device and the object being blew. In practical applications, multiple pre-set distance levels can be stored in the terminal. Each distance level corresponds to different distance information. Based on this, the terminal can determine the target distance level corresponding to the distance information from the multiple stored distance levels based on the distance information obtained from S102 above.

[0038] S106: Control the heating power of the air outlet device according to the target distance level so that the temperature of the air outlet of the air outlet device is maintained at the second temperature.

[0039] The second temperature is related to both the first temperature and the distance information. The temperature at the air outlet of the air outlet device is related to the heating power of the air outlet device. Generally, the higher the heating power of the air outlet device, the higher the temperature at the air outlet; the lower the heating power of the air outlet device, the lower the temperature at the air outlet. Therefore, the temperature at the air outlet device can be controlled by controlling the heating power of the air outlet device.

[0040] The aforementioned air outlet control method, when the air outlet is operating at a preset setting, acquires the first temperature of the air outlet and the distance information between the air outlet and the object being blew on. Then, it determines the target distance level corresponding to the distance information and controls the heating power of the air outlet according to the target distance level, so that the temperature of the air outlet is maintained at a second temperature. This second temperature is related to the first temperature and the distance information. Based on this, the air outlet temperature can be adaptively adjusted according to the distance between the air outlet and the object being blew on. This reduces the difference between the temperature of the air blew from the air outlet to the object and the first temperature, improving the temperature stability of the air blew on the object. It avoids the problem of low drying speed and long drying time caused by a large distance between the air outlet and the object, thereby improving the drying efficiency of the air outlet on the object. It also avoids the problem of localized temperature rise and discomfort caused by a small distance between the air outlet and the object, improving the reliability of the air outlet and ultimately enhancing the user experience.

[0041] In one embodiment, the target distance level may include one of a first distance level, a second distance level, and a third distance level. The distance information corresponding to the third distance level is greater than the distance information corresponding to the second distance level, and the distance information corresponding to the second distance level is greater than the distance information corresponding to the first distance level. For example, the first, second, and third distance levels can be defined based on multiple preset distance thresholds, and the target distance level corresponding to the distance information can be determined by comparing the distance information with each distance threshold.

[0042] For example, if a first distance threshold and a second distance threshold are preset, then the target distance level whose distance information is less than or equal to the first distance threshold is determined as the first distance level; the target distance level whose distance information is greater than the first distance threshold and less than or equal to the second distance threshold is determined as the second distance level; and the target distance level whose distance information is greater than the second distance threshold is determined as the third distance level, wherein the first distance threshold is less than the second distance threshold. For example, if the first distance threshold is 70mm and the second distance threshold is 300mm, then when the distance information L≤70mm, the target distance level is determined as the first distance level; when the distance information 70mm<L≤300mm, the target distance level is determined as the second distance level; and when the distance information L≤300mm, the target distance level is determined as the third distance level. This application does not limit the method of determining the target distance level; it can be set according to the actual application situation. This is merely an exemplary illustration.

[0043] The second temperature at the air outlet of the air outlet device is positively correlated with the target distance level. Specifically, the larger the target distance level, the farther the distance between the air outlet device and the object being blew from, and correspondingly, the higher the second temperature; the smaller the target distance level, the closer the distance between the air outlet device and the object being blew from, and correspondingly, the lower the second temperature.

[0044] The aforementioned air outlet control method quantifies the distance between the air outlet and the object being blown by using a target distance level. Based on the positive correlation between the target distance level and the second temperature, it controls the temperature of the air outlet of the air outlet to be maintained at the second temperature. Thus, the second temperature when the distance between the air outlet and the object being blown is greater than the second temperature when the distance between the air outlet and the object being blown is less, achieving adaptive temperature change of the air outlet temperature with distance. This reduces the difference between the actual temperature blown onto the object and the first temperature, improving drying efficiency while also enhancing the comfort of the object being blown.

[0045] In one embodiment, such as Figure 2 As shown, when the target distance level includes one of the first distance level, the second distance level, and the third distance level, the above step S106: controlling the heating power of the air outlet device according to the target distance level so that the temperature of the air outlet of the air outlet device is maintained at the second temperature may include the following steps S202 to S206.

[0046] S202: When the target distance level is the first distance level, control the heating power of the air outlet device according to the target distance level so that the second temperature of the air outlet device is less than or equal to the first temperature, and the second temperature is negatively correlated with the distance information.

[0047] When the target distance level is the first distance level, the distance between the air outlet device and the object being blew is relatively short. In this case, the heating power of the air outlet device can be controlled so that the second temperature at the air outlet of the air outlet device is lower than the first temperature. Specifically, the second temperature at the air outlet of the air outlet device is negatively correlated with the distance information; that is, the second temperature decreases as the distance information increases, and increases as the distance information decreases.

[0048] S204: When the target distance level is the second distance level, control the heating power of the air outlet device according to the target distance level so that the second temperature of the air outlet device is greater than the first temperature, and the second temperature is positively correlated with the distance information.

[0049] When the target distance level is the second distance level, the distance between the air outlet device and the object being blew is relatively far. In this case, the heating power of the air outlet device can be controlled to make the second temperature at the air outlet of the air outlet device greater than the first temperature. Specifically, the second temperature at the air outlet of the air outlet device is positively correlated with the distance information; that is, the second temperature increases as the distance information increases and decreases as the distance information decreases.

[0050] S206: When the target distance level is the third distance level, control the heating power of the air outlet device according to the target distance level so that the second temperature of the air outlet of the air outlet device is the preset air outlet temperature.

[0051] When the target distance level is the third distance level, the distance between the air outlet and the object being blew is greater than that in the second distance level. In this case, the heating power of the air outlet can be controlled to ensure that the second temperature at the air outlet is the preset air temperature. This satisfies safety requirements within the heating limit of the air outlet and reduces power consumption. The preset air temperature is greater than the first temperature, and it is a pre-set temperature value. For example, the preset air temperature can be set to any suitable value such as 115℃, 118℃, or 120℃, without any limitations.

[0052] The above-mentioned air outlet device control method, when the target distance level is different, controls the heating power of the air outlet device so that when the distance between the air outlet device and the object being blown is close, the second temperature is less than or equal to the first temperature; when the distance is far, the second temperature is greater than the first temperature; and when the distance is even farther, the second temperature is fixed at the preset air outlet temperature. This reduces the temperature difference between the air outlet device and the object being blown and the first temperature, improves the drying efficiency, and reduces the power consumption of the air outlet device.

[0053] In one embodiment, such as Figure 3As shown, the above S202: when the target distance level is the first distance level, the heating power of the air outlet device is controlled according to the target distance level so that the second temperature of the air outlet of the air outlet device is less than or equal to the first temperature, which may include the following S302 and S304.

[0054] S302: When the target distance level is the first distance level, determine the target temperature of the air outlet of the air outlet device based on the first temperature, distance information and the preset first proportional coefficient.

[0055] The first proportional coefficient is a pre-set proportional value, which can be obtained in advance through experiments based on factors such as the air outlet performance of the air outlet device, environmental conditions, and the dryness or humidity of the object being ventilated. The target temperature is the desired temperature at the air outlet of the air outlet device after its heating power has been adjusted. For example, when the target distance level is the first distance level, the target temperature can be determined in the following way:

[0056] T=T0-L / 5*1℃ (1)

[0057] Where T represents the target temperature, T0 represents the first temperature, and L represents the distance between the air outlet and the object being blew. In formula (1), the first proportionality coefficient is 1 / 5.

[0058] S304: Control the heating power of the air outlet device according to the target temperature so that the second temperature of the air outlet of the air outlet device is less than or equal to the first temperature.

[0059] After determining the target temperature at the air outlet of the air outlet device based on S302, the heating power of the air outlet device can be adjusted according to the target temperature. If the target temperature is greater than the first temperature, it indicates that the heating power corresponding to the target temperature is greater than the heating power corresponding to the first temperature. In this case, the heating power of the air outlet device is increased. If the target temperature is less than the first temperature, it indicates that the heating power corresponding to the target temperature is less than the heating power corresponding to the first temperature. In this case, the heating power of the air outlet device is decreased.

[0060] The above-mentioned air outlet control method, when the target distance level is the first distance level, can determine the target temperature of the air outlet of the air outlet based on the first temperature, distance information and the first proportional coefficient, and adjust the heating power of the air outlet according to the target temperature, so that the second temperature of the air outlet of the air outlet is less than or equal to the first temperature. In this way, when the air outlet is close to the object being blew, the air outlet temperature of the air outlet when it is working at the preset level can be reduced, avoiding discomfort caused by a sudden increase in local temperature of the object being blew, and improving the user experience.

[0061] In one embodiment, the aforementioned second distance level may include a first sub-distance level and a second sub-distance level, wherein the distance information of the first sub-distance level is less than the distance information of the second sub-distance level. That is, when the target distance level is the first sub-distance level, the distance between the air outlet and the object being blown is greater than the distance corresponding to the target distance level being the second sub-distance level. For example, the target distance level can be determined as one of the first distance level, the first sub-distance level, the second sub-distance level, and the third distance level based on preset first distance thresholds, second distance thresholds, and sub-distance thresholds. For example, if the first distance threshold is 70mm, the second distance threshold is 300mm, and the sub-distance threshold is 150mm, then when the distance information 70mm < L ≤ 150mm, the target distance level is determined to be the first sub-distance level; when the distance information 150mm < L ≤ 300mm, the target distance level is determined to be the second sub-distance level.

[0062] Based on the above, such as Figure 4 As shown, the above S204: when the target distance level is the second distance level, the heating power of the air outlet device is controlled according to the target distance level so that the second temperature of the air outlet of the air outlet device is greater than the first temperature, which may include the following S402 and S404.

[0063] S402: When the target distance level is the first sub-distance level, the target temperature of the air outlet of the air outlet device is determined according to the first temperature, distance information and the preset first proportional coefficient, and the heating power of the air outlet device is controlled according to the target temperature so that the second temperature of the air outlet of the air outlet device is greater than the first temperature.

[0064] For example, when the target distance level is the first sub-distance level, the target temperature can be determined in the following way:

[0065] T=T0+(L-70) / 5*1℃ (2)

[0066] Where T represents the target temperature, T0 represents the first temperature, and L represents the distance between the air outlet and the object being blew. In formula (2), the first proportionality coefficient is 1 / 5.

[0067] S404: When the target distance level is the second sub-distance level, the target temperature of the air outlet of the air outlet device is determined according to the first temperature, distance information and the preset second proportional coefficient, and the heating power of the air outlet device is controlled according to the target temperature so that the second temperature of the air outlet of the air outlet device is greater than the first temperature.

[0068] The second proportional coefficient differs from the first proportional coefficient. The second proportional coefficient is a pre-set proportional value, which can be obtained through testing based on factors such as the air outlet performance of the air outlet device, environmental conditions, and the dryness or humidity of the object being blew into. In this embodiment, no limitations are placed on the first or second proportional coefficient. For example, when the target distance level is the second sub-distance level, the target temperature can be determined in the following way:

[0069] T=T0+16+(L-150) / 5*0.5℃ (3)

[0070] Where T represents the target temperature, T0 represents the first temperature, and L represents the distance between the air outlet and the object being blew. In formula (3), the second proportionality coefficient is 1 / 10.

[0071] The above-mentioned air outlet control method, when the target distance level is the second distance level, can determine the target temperature of the air outlet of the air outlet based on the first temperature and distance information and the first proportional coefficient or the second proportional coefficient, and adjust the heating power of the air outlet according to the target temperature, so that the second temperature of the air outlet of the air outlet is greater than the first temperature. In this way, when the distance between the air outlet and the object being blew is far, the air outlet temperature of the air outlet when it is working at the preset level can be increased, avoiding the situation that the actual temperature of the air outlet reaching the object being blew is low, resulting in low drying speed and long drying time, thereby improving drying efficiency.

[0072] In one embodiment, for Figure 1 The aforementioned air outlet device control method further includes: controlling the concentration of negative ions released by the air outlet device according to a target distance level. The negative ion concentration is related to distance information. For example, the voltage of the air outlet device can be adjusted according to the target distance level to control the concentration of negative ions released by the air outlet device.

[0073] It is understandable that, given a fixed concentration of negative ions released by the air outlet, the concentration of negative ions acting on the object being blew upon is related to the distance between the air outlet and the object. When the distance between the air outlet and the object is greater, the concentration of negative ions acting on the object is lower; conversely, when the distance is closer, the concentration of negative ions acting on the object is higher. Based on this, this application quantifies the distance between the air outlet and the object by using target distance levels, and adaptively adjusts the concentration of negative ions released by the air outlet according to these target distance levels. This maintains the concentration of negative ions acting on the object at a certain level, achieving the effect of eliminating static electricity and reducing the energy consumption of the air outlet.

[0074] In one embodiment, the target distance level may include one of a third distance level, a fourth distance level, and a fifth distance level. The distance level corresponding to the third distance level is greater than the distance information corresponding to the fourth distance level, and the fourth distance level is greater than the distance information corresponding to the fifth distance level. For example, the third, fourth, and fifth distance levels can be defined based on multiple preset distance thresholds.

[0075] For example, a third distance threshold and a fourth distance threshold are preset. If the distance information is greater than the third distance threshold, the target distance level is determined to be the third distance level; if the distance information is greater than the fourth distance threshold but less than or equal to the third distance threshold, the target distance level is determined to be the fourth distance level; if the distance information is less than or equal to the fourth distance threshold, the target distance level is determined to be the fifth distance level. Here, the third distance threshold is greater than the fourth distance threshold. For example, if the third distance threshold is 300mm and the fourth distance threshold is 50mm, then when the distance information L≥300mm, the target distance level is the third distance threshold; when the distance information 50<L≤300mm, the target distance level is the fourth distance threshold; and when the distance information L≤50mm, the target distance level is the fifth distance level. This application does not limit the method of determining the target distance level; it can be set according to the actual application situation. This is merely an illustrative example.

[0076] The concentration of negative ions released by the air outlet is negatively correlated with the target distance level. Specifically, the concentration of negative ions released by the air outlet at the third target distance level is greater than or equal to the concentration at the fourth target distance level. The concentration of negative ions released by the air outlet at the fourth target distance level is greater than or equal to the concentration at the fifth target distance level.

[0077] The above-mentioned air outlet control method quantifies the distance between the air outlet and the object being blown into a target distance level. When the target distance level is the third, fourth, or fifth distance level, negative feedback control is used to control the concentration of negative ions released by the air outlet. This ensures that the concentration of negative ions acting on the object being blown by the air outlet remains stable regardless of the distance, thereby eliminating static electricity and reducing the energy consumption of the air outlet.

[0078] In one embodiment, such as Figure 5 As shown, the above steps, which control the concentration of negative ions released by the air outlet device according to the target distance level, may include the following steps S502 to S506.

[0079] S502: When the target distance level is the third distance level, control the concentration of negative ions released by the air outlet device to the preset first negative ion concentration.

[0080] When the target distance level is the third distance level, it indicates that the distance between the air outlet and the object being blew into is relatively far. In this case, the voltage of the air outlet can be controlled to adjust the concentration of negative ions released by the air outlet to the first negative ion concentration, so that the negative ion concentration acting on the object being blew into can achieve the effect of static electricity elimination. The first negative ion concentration corresponds to the third distance level and is a preset value that can be obtained through experimental testing; no limitation is made here. For example, the first negative ion concentration is 150 million ions / m³. 3 .

[0081] S504: When the target distance level is the fourth distance level, control the concentration of negative ions released by the air outlet device. The concentration of negative ions is positively correlated with the distance information.

[0082] For example, when the target distance level is the fourth distance level, the target negative ion concentration of the air outlet device can be determined based on the distance information, and the voltage of the air outlet device can be controlled according to this target negative ion concentration to ensure that the negative ion concentration released by the air outlet device is the target negative ion concentration. This maintains a stable level of negative ion concentration on the object being ventilated by the air outlet device, thereby eliminating static electricity. For example, the target negative ion concentration can be determined in the following way:

[0083] Q = 20 million * L / 50 ions / m 3 (4)

[0084] Where Q represents the target negative ion concentration and L represents distance information.

[0085] S506: When the target distance level is the fifth distance level, control the concentration of negative ions released by the air outlet device to the preset second negative ion concentration.

[0086] When the target distance level is the fifth distance level, it indicates that the distance between the air outlet and the object being blew into is relatively short. In this case, the voltage of the air outlet can be controlled to adjust the concentration of negative ions released by the air outlet to the second negative ion concentration. This ensures that the negative ion concentration acting on the object being blew into the air not only provides static electricity elimination but also reduces energy consumption. The second negative ion concentration corresponds to the fifth distance level and is lower than the first negative ion concentration. The second negative ion concentration is a preset value that can be obtained through experimental testing and is not limited here. For example, the first negative ion concentration is 20 million ions / m³. 3 .

[0087] The above-described air outlet control method controls the concentration of negative ions released by the air outlet to the first negative ion concentration when the target distance level is the third distance level; when the target distance level is the fourth distance level, the concentration of negative ions released by the air outlet is controlled based on positive feedback of distance information; and when the target distance level is the fifth distance level, the concentration of negative ions released by the air outlet is controlled to the second negative ion concentration. This achieves adaptive adjustment of the concentration of negative ions released by the air outlet based on the distance between the air outlet and the object being blew, ensuring that the concentration of negative ions acting on the object being blew remains stable regardless of the distance, thereby eliminating static electricity while reducing the energy consumption of the air outlet.

[0088] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0089] In one embodiment, such as Figure 6 As shown, an air outlet device 600 is provided, including a temperature sensor 601, a distance sensor 602, and a controller 603. The temperature sensor 601 acquires a first temperature at the air outlet of the air outlet when the air outlet is operating at a preset setting. The distance sensor 602 acquires distance information between the air outlet and the object being ventilated when the air outlet is operating at the preset setting. The controller 603 is connected to both the temperature sensor 601 and the distance sensor 602. The controller 603 determines a target distance level corresponding to the distance information and controls the heating power of the air outlet according to the target distance level to maintain the temperature of the air outlet at a second temperature; wherein the second temperature is related to both the first temperature and the distance information.

[0090] The aforementioned air outlet device includes a temperature sensor 601, a distance sensor 602, and a controller 603. The temperature sensor 601 can acquire a first temperature at the air outlet when the air outlet device is operating at a preset setting. The distance sensor 602 can acquire distance information between the air outlet device and the object being ventilated when the air outlet device is operating at a preset setting. The controller 603 can determine a target distance level corresponding to the distance information and control the heating power of the air outlet device according to the target distance level to maintain the temperature at the air outlet device at a second temperature. This second temperature is related to the first temperature and the distance information. Based on this, it is possible to... The temperature of the air outlet of the air outlet is adjusted adaptively according to the distance between the air outlet and the object being blew. This reduces the temperature difference between the air outlet temperature and the initial temperature of the object, improving the temperature stability of the air outlet on the object. It avoids the problem of low drying speed and long drying time caused by a large distance between the air outlet and the object, thereby improving the drying efficiency of the air outlet on the object. It also avoids the problem of local temperature rise and discomfort caused by a close distance between the air outlet and the object, improving the reliability of the air outlet and thus enhancing the user experience.

[0091] In one embodiment, the controller 603 is further configured to: when the target distance level is a first distance level, control the heating power of the air outlet device according to the target distance level, so that the second temperature of the air outlet of the air outlet device is less than or equal to the first temperature, and the second temperature is negatively correlated with the distance information; when the target distance level is a second distance level, control the heating power of the air outlet device according to the target distance level, so that the second temperature of the air outlet of the air outlet device is greater than the first temperature, and the second temperature is positively correlated with the distance information; when the target distance level is a third distance level, control the heating power of the air outlet device according to the target distance level, so that the second temperature of the air outlet of the air outlet device is a preset air outlet temperature, and the preset air outlet temperature is greater than the first temperature.

[0092] In one embodiment, the controller 603 is further configured to: determine the target temperature of the air outlet of the air outlet device based on the first temperature, distance information and a preset first proportional coefficient when the target distance level is a first distance level; and control the heating power of the air outlet device based on the target temperature so that the second temperature of the air outlet device is less than or equal to the first temperature.

[0093] In one embodiment, the second distance level includes a first sub-distance level and a second sub-distance level, where the distance information of the first sub-distance level is less than the distance information of the second sub-distance level. The controller 603 is further configured to: when the target distance level is the first sub-distance level, determine the target temperature of the air outlet of the air outlet device based on the first temperature, the distance information, and a preset first proportional coefficient, and control the heating power of the air outlet device according to the target temperature, so that the second temperature of the air outlet of the air outlet device is greater than the first temperature; when the target distance level is the second sub-distance level, determine the target temperature of the air outlet of the air outlet device based on the first temperature, the distance information, and a preset second proportional coefficient, and control the heating power of the air outlet device according to the target temperature, so that the second temperature of the air outlet of the air outlet device is greater than the first temperature; wherein the second proportional coefficient is different from the first proportional coefficient.

[0094] In one embodiment, please refer to... Figure 6 The air outlet device may also include a negative ion device 604, and a controller 603 is also connected to the negative ion device 604. The controller 603 is also used to control the concentration of negative ions released by the negative ion device 604 according to the target distance level. The concentration of negative ions is related to the distance information.

[0095] In one embodiment, the controller 603 is further configured to: control the concentration of negative ions released by the negative ion device 604 to a preset first negative ion concentration when the target distance level is the third distance level; control the concentration of negative ions released by the negative ion device 604 to be positively correlated with the distance information when the target distance level is the fourth distance level; and control the concentration of negative ions released by the negative ion device 604 to be a preset second negative ion concentration when the target distance level is the fifth distance level; wherein the second negative ion concentration is less than the first negative ion concentration.

[0096] In one embodiment, such as Figure 7 The diagram illustrates another method for controlling an air outlet device. Taking a hair dryer as an example, where the air outlet device is hair and the object being blown is hair, this method is explained exemplarily. The hair dryer includes a heating element, a temperature sensor, a distance sensor, a controller, and a negative ion generator.

[0097] Based on user habits and relevant test data, it was found that setting the air outlet temperature of a hair dryer to 80℃±10℃ is a suitable temperature for drying hair. When using a hair dryer, the distance between the user's hand holding the hair dryer and their hair is generally around 100±10mm.

[0098] Based on the above, when the hair dryer is turned on at its high temperature setting, the heating element heats up according to the set power P0. The temperature sensor detects the temperature at the air outlet. When the air outlet temperature reaches the set first temperature T0 = 80℃, the heating element outputs power stably, and the air temperature acting on the user's hair remains at T0. At this time, the distance sensor detects the distance L between the user's hair and the hair dryer. The controller adjusts the heating power of the heating element according to the set program based on the different distances L, thereby controlling the air outlet temperature of the hair dryer. Simultaneously, the controller controls the concentration of negative ions released by the negative ion generator.

[0099] The controller adjusts the heating element power and thus the air outlet temperature based on different distances as follows: When the distance L is within the range of 0-70mm, the air outlet temperature is adjusted in real-time according to T01 = T0 - L / 5 * 1℃. Because the distance L is relatively close within this range, the air outlet temperature of the hair dryer is relatively high, which may affect the user's fur and hair and cause damage. Therefore, the program is set to gradually decrease the air outlet temperature in real-time according to T = T0 - L / 5 * 1℃ to protect the user's fur and hair and improve the user experience. When the distance L is within the range of 70-150mm, the air outlet temperature is adjusted in real-time according to T = T0 + (L - 70) / 5 * 1℃. When the distance L is within the range of 150-300mm, the air outlet temperature is adjusted in real-time according to T = T0 + 16℃ + (L - 150) / 5 * 0.5℃. When the distance L exceeds 300mm, the air outlet temperature is set to the maximum temperature T = 115℃ and the heating element power is no longer adjusted in real-time.

[0100] The specific process by which the controller adjusts the concentration of negative ions released by the negative ion generator according to different distances is as follows: When the distance L is between 0-50mm, the concentration of negative ions released by the negative ion generator is Q = 20 million ions / m. 3 When L is between 50-300 mm, the concentration of negative ions released by the negative ion generator is Q = 20 million * L / 50 ions / m 3 The negative ion concentration is adjusted in real time; when the distance L exceeds 300mm, the negative ion concentration released by the negative ion device is Q = 150 million ions / m³. 3 .

[0101] The aforementioned hair dryer can adjust the air temperature and negative ion concentration in real time based on the distance between the hair dryer and the user. Even if the distance between the hair dryer and the user's hair changes during use, it can still maintain the set air temperature and negative ion concentration to dry the hair. This reduces the user's hair drying time and the frequency of frequent temperature adjustments, prevents damage to the user from excessively high hair dryer temperatures, and can also quickly increase the drying speed and time, thereby improving the drying rate of the hair dryer. It can also eliminate static electricity, improve the safety, reliability, and convenience of product use, and enhance the user experience.

It avoids the problem of low drying speed and long drying time caused by a large distance between the device and the object, thus improving the drying efficiency of the device.
