[0054] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0055] In the description of the embodiments of the present application, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0059] Figure 6 The schematic diagram of the connection relationship between the temperature detection module, the control module, the heating module and the prompt module provided in the embodiment of the present application is illustrated as follows: Figure 6 As shown, the hair dryer 400 of the present application includes a shell (not shown), a heating module 30, a motor, a fan, a temperature detection module 10, a control module 20 and a filter (not shown). An air duct is formed inside the shell, and an air inlet and an air outlet connected to the air duct are provided on the shell. The filter is detachably installed on the air inlet. Specifically, the filter is installed on the air inlet by screws or buckles.

[0060] The motor and the fan are arranged in the air duct, the heating module 30 is arranged in the air duct near the air outlet, and the temperature detection module 10 is arranged at the air outlet. The temperature detection module 10 is generally an NTC thermistor, and can also be other components with the same effect. If the wind temperature is too high, it is easy to damage the hair and there are safety hazards such as sol fire, so it is necessary to add a temperature detection module 10 to detect the real-time wind temperature of the air outlet. The temperature detection module 10 converts the real-time wind temperature into a wind temperature signal and feeds it back to the control module 20. After the control module 20 processes the information, it adjusts the power of the heating module 30 to achieve a constant temperature effect.

[0061] Furthermore, the shell includes a shell body (not shown) and a handle (not shown) connected to the shell body, the air duct includes an air inlet duct (not shown) and an air outlet duct (not shown) connected to the air inlet duct, the motor and the fan are arranged in the air inlet duct, the air outlet is connected to the air outlet duct, and the air inlet is connected to the air inlet duct.

[0062] Further, a wind speed sensor or a pressure sensor is provided in the air duct, and the wind speed sensor or the pressure sensor is electrically connected to the control module 20. The wind speed sensor is used to detect the wind speed in the air duct, and the control module 20 determines whether the filter is blocked by wind according to the wind speed. The pressure sensor is used to detect the pressure change in the air duct, and the control module 20 determines whether the filter is blocked by wind according to the pressure.

[0063] In a specific embodiment, the wind speed sensor is arranged in the air inlet duct or the air outlet duct, preferably, the wind speed sensor is arranged in the air outlet duct. The pressure sensor is arranged in the air inlet duct or the air outlet duct. Since the pressure in the air inlet duct changes greatly when air blockage occurs, the pressure sensor is arranged in the air inlet duct to improve the detection accuracy.

[0064] Figure 1 One of the flow charts of the method for detecting air blockage of a hair dryer provided in an embodiment of the present application is illustrated, such as Figure 1 As shown, the method for detecting wind blockage of a hair dryer includes:

[0065] Step S100, collecting working parameters of the hair dryer 400, wherein the working parameters include a wind speed value in an air duct of the hair dryer 400, or an air pressure value in the air duct;

[0066] Step S200, when the working parameters meet the preset conditions, determine that the filter of the hair dryer 400 is blocked; wherein the preset conditions include a wind speed value less than a preset wind speed value or an air pressure value less than a preset pressure value.

[0067] According to the method for detecting air blockage of a hair dryer in the embodiment of the present application, the wind speed value or the air pressure value in the air duct of the hair dryer 400 is detected to determine whether the filter is blocked, thereby realizing the function of automatic judgment. Compared with manual observation, the method has the advantages of accurate detection results and easy use, and effectively extends the service life of the hair dryer 400.

[0068] It is understandable that, in general, when the wind speed value decreases by 10%-50%, it is determined that the filter of the hair dryer 400 is blocked. Specifically, the wind speed of the hair dryer is generally 10m / s-20m / s. When the wind speed is less than the above range, it can be determined that the filter of the hair dryer 400 is blocked. In order to prevent misjudgment, the preset wind speed value can be 8m / s. Of course, the preset wind speed value is not limited thereto, and the optimal value is obtained according to the experimental results.

[0069] It is understandable that when the filter is blocked, the air pressure value in the air outlet duct is greater than or equal to the external air pressure value, and the air pressure value in the air inlet duct is less than the external air pressure value. At this time, the air inlet duct is under negative pressure, and the more serious the blockage of the filter is, the greater the absolute value of the negative pressure is. Therefore, in order to have higher detection accuracy, the pressure sensor is preferably arranged in the air inlet duct. When the filter is blocked, the air flow rate in the duct is greatly reduced because the air flow entering the air inlet duct through the filter is reduced. The smaller the wind speed value, the more serious the blockage of the filter is. Therefore, the wind speed can be used to determine whether the filter is blocked. Similarly, when the air pressure value decreases by 10%-50%, it is determined that the filter of the hair dryer 400 is blocked.

[0070] It should be noted here that, since the speed of the motor rotation of each gear is different, the wind speed value of each gear is different, and the wind speed of each gear when blocking the wind is also different. Therefore, there can be multiple preset wind speed values, and the preset wind speed values ​​correspond to the gears one by one. Similarly, the air pressure value of each gear is different, and the air pressure value of each gear when blocking the wind is also different. Therefore, there can be multiple preset pressure values, and the preset pressure values ​​correspond to the gears one by one.

[0071] It is understandable that the air inlet of the fan is provided with a Hall sensor, which is electrically connected to the control module 20. The Hall sensor is suitable for detecting whether the filter screen at the air inlet is installed in place. During the process of removing or installing the filter screen, the Hall sensor generates an electrical signal and sends it to the control module 20, and the timing module inside the control module 20 starts timing, and the timing duration is the usage duration of the filter screen. During the use of the hair dryer 400, the dust and lint on the surface of the filter screen increase with the increase of the usage duration, making the filter screen more and more blocked. Therefore, the usage duration of the filter screen can be used to judge whether the filter screen is blocked. However, since the usage scenario of the hair dryer 400 is different each time, the amount of dust and lint in the air is also different. It is easy to make a misjudgment if the hair dryer 400 is blocked only by the usage duration, which affects the user experience. Therefore, the blocking condition of the hair dryer 400 can be judged by combining the working parameters with the usage duration, thereby effectively improving the accuracy of the judgment result.

[0072] Before the step of collecting the working parameters of the hair dryer 400, the method further includes:

[0073] Obtain the removal time of the filter, and determine the usage time starting from the removal time;

[0074] The working parameters of the hair dryer 400 are collected:

[0075] When the usage time is longer than the preset time, the working parameters of the hair dryer 400 are collected.

[0076] During the process of removing the filter, the filter is away from the Hall sensor, and the Hall sensor generates a first electrical signal and sends it to the control module 20. The timing module inside the control module 20 starts timing, and the timing duration is the usage time of the filter. When the usage time is longer than the preset time, it means that the filter may be blocked, so the control module 20 starts to collect the working parameters of the hair dryer 400, and determines whether the filter is blocked by judging whether the working parameters meet the preset conditions. By adopting a judgment method combining time and working parameters, the accuracy of the judgment result is effectively improved, the user experience is improved, and the product competitiveness is enhanced.

[0077] Figure 2 The second flowchart of the method for detecting air blockage of a hair dryer provided in the embodiment of the present application is illustrated. Figure 2 Describe a specific embodiment of the present application, such as Figure 2 As shown, the method for detecting wind blockage of a hair dryer includes:

[0078] Step S90, obtaining the removal time of the filter screen, and determining the usage time starting from the removal time;

[0079] Step S100, when the usage time is longer than the predetermined time, collecting the working parameters of the hair dryer 400, wherein the working parameters include the wind speed value in the air duct of the hair dryer 400, or the air pressure value in the air duct;

[0080] Step S200, when the working parameters meet the preset conditions, determine that the filter of the hair dryer 400 is blocked; wherein the preset conditions include a wind speed value less than a preset wind speed value or an air pressure value less than a preset pressure value.

[0081] It is understandable that when the use time is calculated by taking the filter removal time as the starting point, the use time includes the time from the removal of the filter to the installation of the filter, that is, the cleaning time of the filter. If the cleaning time of the filter accounts for too high a proportion of the use time, it will affect the accuracy of judging whether the filter is blocked by the use time. Therefore, the present application also provides a method for judging whether the filter is blocked by the air when the cleaning time accounts for too high a proportion of the use time. Before the step of collecting the working parameters of the hair dryer 400, the hair dryer air blockage detection method also includes:

[0082] Obtain the installation time of the filter and determine the usage time starting from the installation time;

[0083] The working parameters of the hair dryer 400 are collected:

[0084] When the usage time is longer than the preset time, the working parameters of the hair dryer 400 are collected.

[0085] Since the usage time is calculated based on the installation time as the starting point in the present embodiment, the usage time does not include the cleaning time of the filter, which effectively improves the accuracy of the judgment through the usage time.

[0086] Figure 3 The third flowchart of the method for detecting wind blockage of a hair dryer provided in the embodiment of the present application is illustrated. Figure 3 Describe a specific embodiment of the present application, such as Figure 3 As shown, the method for detecting wind blockage of a hair dryer includes:

[0087] Step S90, obtaining the installation time of the filter, and determining the usage time starting from the installation time;

[0088] Step S100, when the usage time is longer than the predetermined time, collecting the working parameters of the hair dryer 400, wherein the working parameters include the wind speed value in the air duct of the hair dryer 400, or the air pressure value in the air duct;

[0089] Step S200, when the working parameters meet the preset conditions, determine that the filter of the hair dryer 400 is blocked; wherein the preset conditions include a wind speed value less than a preset wind speed value or an air pressure value less than a preset pressure value.

[0090] During the use of the hair dryer 400, the temperature detection module 10 monitors the temperature value of the air outlet in real time, and feeds back the wind temperature signal to the control module 20. After the information is processed by the control module 20, the power of the heating module 30 is adjusted to achieve a constant temperature effect. When the filter is seriously blocked, the air volume blown out by the hair dryer 400 is very small, and the heat generated is also very small, resulting in a long hair drying time, which seriously affects the user experience. And when the filter reaches a certain degree of blockage, even if the heating module 30 does not heat up, the motor of the hair dryer 400 will cause serious heating of the motor when it runs in a negative pressure environment, which can easily burn the motor. In order to prevent damage to the motor due to air blockage, the detection method introduces a step of judging air blockage by temperature.

[0091] It is understandable that before the step of collecting the working parameters of the hair dryer 400, the following steps are also included:

[0092] Get the motor current of the hair dryer;

[0093] The working parameters of the hair dryer 400 are collected:

[0094] When the motor current is greater than the first current value, the working parameters of the hair dryer 400 are collected. For example, under normal working conditions, the motor current is generally 0.1A-0.3A, so the first current value is 0.4A. When the motor current is greater than 0.4A, the working parameters of the hair dryer 400 are collected.

[0095] It is understandable that before the step of collecting the working parameters of the hair dryer 400, the following steps are also included:

[0096] Obtain the temperature value of the air outlet of the hair dryer 400;

[0097] The working parameters of the hair dryer 400 are collected:

[0098] When the temperature value is lower than the first preset temperature, the working parameters of the hair dryer 400 are collected.

[0099] When the temperature value of the air outlet of the hair dryer 400 is lower than the first preset temperature, it indicates that the filter may be blocked, and the control module 20 starts to collect the working parameters of the hair dryer 400, and determines whether the filter is blocked by the working parameters. By using the relationship between the temperature of the air outlet and the first preset temperature as the starting condition for collecting the working parameters of the hair dryer 400, it is effectively avoided that the motor is damaged due to long-term operation in a negative pressure environment. The temperature value of the air outlet of the hair dryer 400 is generally between 30°C and 60°C, so the first preset temperature can be 30°C.

[0100] Figure 4 The fourth flowchart of the method for detecting air blockage of a hair dryer provided in the embodiment of the present application is illustrated. Figure 4 Describe a specific embodiment of the present application, such as Figure 4 As shown, the method for detecting wind blockage of a hair dryer includes:

[0101] Step S90, obtaining the temperature value of the air outlet of the hair dryer 400;

[0102] Step S100, when the temperature value is lower than the first preset temperature, collecting the working parameters of the hair dryer 400, wherein the working parameters include the wind speed value in the air duct of the hair dryer 400, or the air pressure value in the air duct;

[0103] Step S200, when the working parameters meet the preset conditions, determine that the filter of the hair dryer 400 is blocked; wherein the preset conditions include a wind speed value less than a preset wind speed value or an air pressure value less than a preset pressure value.

[0104] Furthermore, since the power output of the heating module 30 of the hair dryer 400 is different at each gear, when the hair dryer 400 is adjusted from the high temperature gear to the low temperature gear, the temperature value of the air outlet of the hair dryer 400 will decrease. If the temperature value of the air outlet is compared with a first preset temperature, it is easy to cause misjudgment. Therefore, the first preset temperature can be multiple temperature values, and the first preset temperature corresponds to the gear one by one, that is, one gear corresponds to one first preset temperature.

[0105] It is understandable that the hair dryer 400 further includes a prompt module 40, which is electrically connected to the control module 20. After determining that the filter screen of the hair dryer 400 is blocked, the following steps are further included:

[0106] Output a prompt message, the prompt message is used to remind the user to clean the filter.

[0107] The control module 20 sends a prompt message to the prompt module 40, and the prompt module 40 outputs the prompt message to remind the user to clean the filter in time. After receiving the prompt message, the user cleans the filter, which can avoid the filter blocking the air for a long time and causing damage to the motor, and can effectively extend the service life of the hair dryer 400. After the user cleans the filter, the prompt module 40 stops outputting the prompt message.

[0108] It is understandable that the prompt information includes display information, light, sound or vibration.

[0109] When the prompt information includes display information, the prompt module 40 includes a display screen, which is electrically connected to the control module 20. The display screen is arranged on the outer surface of the shell. Preferably, the display screen is arranged at a position of the shell body that is easily visible to the user, so as to facilitate the user to view the display information. The display information can be text, for example, the display information can be "The filter is blocked, please clean the filter" or "Please clean the filter". Of course, the specific type of display information is not limited to this, and it can also be other text information. Of course, the display information can also be an icon, for example, the icon can be a filter icon or a cleaning brush icon. When the user sees the filter icon or the cleaning brush icon, he can know that the filter is blocked; of course, the specific type of icon is not limited to this, and it can also be other types of icons.

[0110] When the prompt information includes a light, the prompt module 40 includes an indicator light, the indicator light is electrically connected to the control module 20, and the indicator light is arranged on the housing. Preferably, the indicator light is arranged at a position where the housing body is easily visible to the user, so as to facilitate the user to view. One indicator light can be set. When one indicator light is set, the indicator light can display two different colors, for example, the indicator light can display red and green. During normal use, the indicator light emits a green light, indicating that the hair dryer 400 is working normally and the filter is not blocked; when the filter is blocked, the indicator light emits a red light, indicating that the filter is blocked, so as to remind the user to clean the filter in time. Of course, the indicator light can also be unlit during normal use, and only when the filter is blocked, the indicator light emits a red light. Two indicator lights can also be set, that is, one red indicator light and one green indicator light. When two indicator lights are set, the green indicator light is lit when the hair dryer 400 is used normally; when the filter is blocked, the red indicator light is lit.

[0111] In order to reduce the energy consumption of the indicator light, the indicator light lights up once at a predetermined interval, that is, the indicator light flashes for indication. This indication method can not only reduce the energy consumption of the indicator light, but also shorten the working time of the indicator light and extend the service life of the indicator light.

[0112] When the prompt information includes sound, the prompt module 40 includes a buzzer, which is electrically connected to the control module 20. The buzzer is arranged in the housing, and a sound-transmitting hole corresponding to the position of the buzzer is arranged on the housing. In normal use, the buzzer does not make a sound; when the filter is blocked, the buzzer makes a sound to remind the user to clean the filter.

[0113] When the prompt information includes vibration, the prompt module 40 includes a vibrator, which is arranged in the housing, and includes a small motor and an eccentric block, and the rotating shaft of the small motor is connected to the eccentric block. The small motor is electrically connected to the control module 20. In normal use, the vibrator does not vibrate; when the filter is blocked, the vibrator starts to vibrate to remind the user to clean the filter.

[0114] A specific embodiment of the present application is described below. The method for detecting air blockage of a hair dryer includes:

[0115] Step S100, collecting working parameters of the hair dryer 400, wherein the working parameters include a wind speed value in an air duct of the hair dryer 400, or an air pressure value in the air duct;

[0116] Step S200, when the working parameters meet the preset conditions, determining that the filter of the hair dryer 400 is blocked; wherein the preset conditions include that the wind speed value is less than the preset wind speed value or the air pressure value is less than the preset pressure value;

[0117] Step S300: outputting a prompt message, where the prompt message is used to remind the user to clean the filter.

[0118] It is understandable that, before the step of collecting the working parameters of the hair dryer 400, the method for detecting air blockage of the hair dryer further includes:

[0119] Obtaining the temperature rise rate of the air outlet of the hair dryer 400 when it is turned on;

[0120] The working parameters of the hair dryer 400 are collected:

[0121] When the heating rate is greater than the preset heating rate, the working parameters of the hair dryer 400 are collected.

[0122] When the filter is not blocked, the temperature rise rate of the air outlet is fixed or within a certain range when the machine is turned on. When the filter is blocked, the airflow entering the air duct decreases after the hair dryer 400 is turned on, and the temperature rise rate of the air outlet increases. When the temperature rise rate is greater than the preset temperature rise rate, it indicates that the filter of the hair dryer 400 may be blocked, so it is necessary to collect the working parameters of the hair dryer 400 to confirm whether the filter is blocked. Specifically, when the temperature rise rate is greater than 5%-30% of the preset temperature rise rate, it can be determined that the filter may be blocked.

[0123] It should be noted here that the heating rate refers to the ratio of the temperature increase per unit time to the time.

[0124] Figure 5 The fifth flowchart of the method for detecting wind blockage of a hair dryer provided in the embodiment of the present application is illustrated. Figure 5 Describe a specific embodiment of the present application, such as Figure 5 As shown, the method for detecting wind blockage of a hair dryer includes:

[0125] Step S90, obtaining the temperature rise rate of the air outlet of the hair dryer 400 when it is turned on;

[0126] Step S100, when the heating rate is greater than a preset heating rate, collecting working parameters of the hair dryer 400, wherein the working parameters include a wind speed value in an air duct of the hair dryer 400, or an air pressure value in the air duct;

[0127] Step S200, when the working parameters meet the preset conditions, determine that the filter of the hair dryer 400 is blocked; wherein the preset conditions include a wind speed value less than a preset wind speed value or an air pressure value less than a preset pressure value.

[0128] It is understandable that, after the step of outputting the prompt information, the method for detecting wind blockage of the hair dryer further includes:

[0129] A shutdown command is output to stop the hair dryer 400 from working.

[0130] When the hair dryer 400 is blocked, the motor runs in a negative pressure environment, which may cause the motor to heat up severely and easily burn out. Therefore, after the step of outputting the prompt message, a shutdown command is output to stop the motor from rotating, so as to prevent the motor from running in a negative pressure environment for a long time and causing damage to the motor.

[0131] A specific embodiment of the present application is described below. The method for detecting air blockage of a hair dryer includes:

[0132] Step S100, collecting working parameters of the hair dryer 400, wherein the working parameters include a wind speed value in an air duct of the hair dryer 400, or an air pressure value in the air duct;

[0133] Step S200, when the working parameters meet the preset conditions, determining that the filter of the hair dryer 400 is blocked; wherein the preset conditions include that the wind speed value is less than the preset wind speed value or the air pressure value is less than the preset pressure value;

[0134] Step S300, outputting a prompt message, the prompt message is used to remind the user to clean the filter;

[0135] Step S400, outputting a shutdown command to stop the hair dryer 400 from working.

[0136] It is understandable that, after the step of outputting the prompt information, the method for detecting wind blockage of the hair dryer further includes:

[0137] Get the motor temperature of the hair dryer 400;

[0138] When the motor temperature is greater than the second preset temperature, a low-speed rotation instruction is output to keep the motor of the hair dryer 400 rotating at a low speed, thereby cooling the motor.

[0139] When the hair dryer 400 is blocked, the motor runs at high speed in a negative pressure environment, which will cause the motor to heat up seriously. If the motor works in a high temperature environment for a long time, the motor will be damaged. Therefore, by obtaining the motor temperature of the hair dryer 400, when the motor temperature is greater than the second preset temperature, a low-speed rotation instruction is output to keep the motor of the hair dryer 400 rotating at a low speed. During the low-speed rotation process, the motor drives the fan to rotate, and the fan drives the low-temperature air in the air duct to blow toward the motor, thereby cooling the motor itself to prevent the motor from being damaged due to high temperature.

[0140] A specific embodiment of the present application is described below. The method for detecting air blockage of a hair dryer includes:

[0141] Step S100, collecting working parameters of the hair dryer 400, wherein the working parameters include a wind speed value in an air duct of the hair dryer 400, or an air pressure value in the air duct;

[0142] Step S200, when the working parameters meet the preset conditions, determining that the filter of the hair dryer 400 is blocked; wherein the preset conditions include that the wind speed value is less than the preset wind speed value or the air pressure value is less than the preset pressure value;

[0143] Step S300, outputting a prompt message, the prompt message is used to remind the user to clean the filter;

[0144] Step S400, obtaining the motor temperature of the hair dryer 400;

[0145] Step S500, when the motor temperature is greater than the second preset temperature, a low-speed rotation instruction is output to keep the motor of the hair dryer 400 rotating at a low speed, thereby cooling the motor.

[0146] It is understandable that after the motor rotates at a low speed for a certain period of time, the temperature of the motor decreases. At this time, the hair dryer 400 has a small wind force and a low temperature due to the air blockage of the filter screen, and the hair dryer 400 can be turned off. Therefore, after the step of outputting the prompt information, the hair dryer air blockage detection method further includes:

[0147] A shutdown command is output to stop the hair dryer 400 from working.

[0148] A specific embodiment of the present application is described below. The method for detecting air blockage of a hair dryer includes:

[0149] Step S100, collecting working parameters of the hair dryer 400, wherein the working parameters include a wind speed value in an air duct of the hair dryer 400, or an air pressure value in the air duct;

[0150] Step S200, when the working parameters meet the preset conditions, determining that the filter of the hair dryer 400 is blocked; wherein the preset conditions include that the wind speed value is less than the preset wind speed value or the air pressure value is less than the preset pressure value;

[0151] Step S300, outputting a prompt message, the prompt message is used to remind the user to clean the filter;

[0152] Step S400, obtaining the motor temperature of the hair dryer 400;

[0153] Step S500, when the motor temperature is greater than the second preset temperature, outputting a low-speed rotation instruction to keep the motor of the hair dryer 400 rotating at a low speed, thereby cooling the motor;

[0154] Step S600, outputting a shutdown command to stop the hair dryer 400 from working.

[0155] According to the method for detecting air blockage of a hair dryer in the embodiment of the present application, whether the filter is blocked is determined by detecting the wind speed value or the air pressure value in the air duct of the hair dryer, thereby realizing the function of automatic judgment. Compared with manual observation, the method has the advantages of accurate detection results and easy use, and effectively extends the service life of the hair dryer.
