Description

Technical Field

[0001] This invention relates to the field of hair dryer technology, and in particular to a hair dryer control method, device, hair dryer, and computer-readable storage medium. Background Technology

[0002] In existing technology, when a hair dryer is in operation, if the air inlet of the hair dryer is blocked, the airflow will decrease, resulting in reduced heat dissipation and causing the heating element to continue heating. Due to the reduced heat dissipation, the temperature of the thermal fuse will continue to rise, eventually triggering a fault protection shutdown due to overheating of the thermal fuse.

[0003] On the one hand, after the shutdown protection is activated, the heating element and motor shut down simultaneously. However, because the residual heat of the heating element cannot dissipate, it will continue to heat the thermal fuse and cause it to melt. After the thermal fuse melts, the hair dryer cannot be used normally. Furthermore, when the hair dryer is restarted after the shutdown protection is activated, the thermal fuse is still at a high temperature, which will prevent the hair dryer from starting normally. It is necessary to wait for the heat to dissipate before the hair dryer can be turned on normally. On the other hand, after the malfunction shutdown, the heating element still has residual heat, and the hair dryer casing will become hot due to excessive temperature. Users are likely to be burned if they touch the hair dryer body. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, one objective of this invention is to provide a hair dryer control method. This method can obtain the temperature of the hair dryer's thermal fuse when the air inlet of the hair dryer is blocked. By judging the temperature range of the thermal fuse, the method controls the hair dryer to execute different over-temperature protection strategies to dissipate heat and cool down the hair dryer, thereby avoiding the hair dryer from failing to start or be used due to excessive temperature, and preventing the user from being burned by excessive temperature, thereby improving the reliability and safety of the hair dryer.

[0006] Therefore, a second objective of the present invention is to provide a hair dryer control device.

[0007] Therefore, a third objective of this invention is to provide a hair dryer.

[0008] Therefore, a fourth object of the present invention is to provide a computer-readable storage medium.

[0009] To achieve the above objectives, an embodiment of the first aspect of the present invention discloses a hair dryer control method, comprising: determining that the air inlet of the hair dryer is blocked, obtaining the temperature of the temperature fuse of the hair dryer; and controlling the hair dryer to execute different over-temperature protection strategies according to the temperature range of the temperature fuse.

[0010] According to the hair dryer control method of the present invention, when the air inlet of the hair dryer is blocked, the temperature of the thermal fuse of the hair dryer can be obtained. Based on the judgment result of the temperature range of the thermal fuse, the hair dryer can be controlled to execute different over-temperature protection strategies to dissipate heat and cool down the hair dryer, so as to avoid the hair dryer failing to start and be used due to excessive temperature, and to avoid the user being burned due to excessive temperature, thereby improving the reliability and safety of the hair dryer.

[0011] In addition, the hair dryer control method according to the above embodiments of the present invention may also have the following additional technical features:

[0012] In some examples, the hair dryer is controlled to perform different over-temperature protection strategies based on the temperature range of the thermal fuse, including: when it is determined that the temperature of the thermal fuse is greater than or equal to a first preset temperature and less than a second preset temperature for a continuous first preset time, the hair dryer is controlled to perform a first over-temperature protection strategy.

[0013] In some examples, the first over-temperature protection strategy includes: controlling the heating element of the hair dryer to shut down, and controlling the blowing element of the hair dryer to keep running.

[0014] In some examples, the hair dryer is controlled to perform different over-temperature protection strategies based on the temperature range of the temperature fuse. This also includes: after the heating element of the hair dryer is turned off, when it is determined that the temperature of the temperature fuse is greater than or equal to the second preset temperature for a continuous second preset time, the hair dryer is controlled to perform a second over-temperature protection strategy.

[0015] In some examples, the second over-temperature protection strategy includes controlling the blower's airflow component to shut down.

[0016] In some examples, after controlling the blower's blowing component to shut down, the function also includes: outputting a first preset alarm signal.

[0017] In some examples, after controlling the blower's air-blowing component to turn off, the method further includes: in response to a command to restart the hair dryer, controlling the air-blowing component to turn on again to restart the hair dryer; after restarting the hair dryer, obtaining the current temperature of the thermal fuse; when it is determined that the current temperature of the thermal fuse is less than the set temperature corresponding to the hair dryer in the current operating mode, controlling the heating component to remain on; or, when it is determined that the current temperature of the thermal fuse is greater than or equal to the set temperature corresponding to the hair dryer in the current operating mode, controlling the heating component to remain off until the current temperature of the thermal fuse is less than the set temperature corresponding to the hair dryer in the current operating mode, then controlling the heating component to turn on.

[0018] In some examples, after obtaining the temperature of the thermal fuse of the hair dryer, the method further includes: obtaining the current operating mode of the hair dryer; and controlling the operating power of the heating element according to the operating mode.

[0019] In some examples, controlling the operating power of the thermal fuse according to the operating mode includes: determining a reference operating power, an upper limit value, and a lower limit value for the heating element corresponding to the operating mode; controlling the heating element to operate according to the reference operating power, and correcting the operating power of the heating element during the process of controlling the heating element to operate according to the reference operating power, so that the operating power of the heating element is maintained between the upper limit value and the lower limit value, wherein the difference between the upper limit value and the lower limit value is less than a preset value.

[0020] In some examples, determining the reference operating power, upper limit of operating power, and lower limit of operating power of the heating component corresponding to the operating mode includes: querying a preset working mode and power parameter correspondence table to obtain the reference operating power, upper limit of operating power, and lower limit of operating power of the heating component corresponding to the operating mode. The preset working mode and power parameter correspondence table includes multiple working modes and the reference operating power, upper limit of operating power, and lower limit of operating power corresponding to each working mode.

[0021] The operation power of the heating element is adjusted as follows: when the temperature of the thermal fuse is lower than the set temperature in the operating mode, the operation power of the heating element is increased until the temperature of the thermal fuse reaches the set temperature in the operating mode; when the temperature of the thermal fuse is higher than the set temperature in the operating mode, the operation power of the heating element is decreased until the temperature of the thermal fuse reaches the set temperature in the operating mode; when the temperature of the thermal fuse is equal to the set temperature in the operating mode, the operation power of the heating element remains unchanged.

[0022] In some examples, during the process of increasing the operating power of the heating element, if the operating power of the heating element increases to the upper limit of the operating power and the temperature of the thermal fuse does not reach the set temperature of the operating mode, then the heating element is controlled to continue operating at the upper limit of the operating power until the temperature of the thermal fuse reaches the set temperature of the operating mode.

[0023] In some examples, during the process of reducing the operating power of the heating element, if the operating power of the heating element decreases to the lower limit of the operating power and the temperature of the thermal fuse does not reach the set temperature of the operating mode, then the heating element is controlled to continue operating at the lower limit of the operating power until the temperature of the thermal fuse reaches the set temperature of the operating mode.

[0024] In some examples, the control method for the hair dryer further includes: determining whether the temperature fuse is in a faulty state; if so, controlling the hair dryer to stop and outputting a second alarm signal.

[0025] In some examples, after controlling the hair dryer to stop and outputting a second alarm signal, the method further includes: in response to an instruction to restart the hair dryer, controlling the hair dryer to restart, and determining whether the temperature fuse is still in a faulty state after restarting; if so, controlling the hair dryer to stop and keeping it in a power-off disabled state.

[0026] In some examples, the fault state includes an open circuit state or a short circuit state. Determining whether the thermal fuse is in a fault state includes: determining that the thermal fuse is in an open circuit state when the temperature of the thermal fuse is greater than or equal to a third preset temperature for a continuous third preset time period; and determining that the thermal fuse is in a short circuit state when the temperature of the thermal fuse is less than a fourth preset temperature for a continuous fourth preset time period.

[0027] In some examples, whether the air inlet of the hair dryer is blocked is determined based on the air pressure at the air inlet and the rate of temperature change of the thermal fuse.

[0028] To achieve the above objectives, a second aspect of the present invention discloses a control device for a hair dryer, comprising: an acquisition module for acquiring the temperature of a thermal fuse of the hair dryer when it is determined that the air inlet of the hair dryer is blocked; and a control module for controlling the hair dryer to execute different over-temperature protection strategies according to the temperature range of the thermal fuse.

[0029] According to the control device of the hair dryer according to the embodiment of the present invention, when the air inlet of the hair dryer is blocked, the temperature of the thermal fuse of the hair dryer can be obtained. Based on the judgment result of the temperature range of the thermal fuse, the hair dryer is controlled to execute different over-temperature protection strategies to dissipate heat and cool down the hair dryer, so as to avoid the hair dryer failing to start and use due to excessive temperature and the user being burned due to excessive temperature, thereby improving the reliability and safety of the hair dryer.

[0030] To achieve the above objectives, a third aspect of the present invention discloses a hair dryer, which includes: a hair dryer control device as described in the second aspect of the present invention; or, a processor, a memory, and a hair dryer control program stored in the memory and executable on the processor, wherein the hair dryer control program, when executed by the processor, implements the hair dryer control method as described in the first aspect of the present invention.

[0031] According to an embodiment of the present invention, when the air inlet of the hair dryer is blocked, the temperature of the thermal fuse of the hair dryer can be obtained. Based on the judgment result of the temperature range of the thermal fuse, the hair dryer can be controlled to implement different over-temperature protection strategies to dissipate heat and cool down the hair dryer, so as to avoid the hair dryer failing to start and be used due to excessive temperature, and to avoid the user being burned due to excessive temperature, thereby improving the reliability and safety of the hair dryer.

[0032] To achieve the above objectives, a fourth aspect of the present invention discloses a computer-readable storage medium storing a control program for a hair dryer, wherein the control program for the hair dryer, when executed by a processor, implements the hair dryer control method as described in the first aspect of the present invention.

[0033] According to an embodiment of the present invention, when the control program for a hair dryer stored thereon is executed by a processor, if the air inlet of the hair dryer is blocked, the temperature of the thermal fuse of the hair dryer can be obtained. Based on the judgment result of the temperature range of the thermal fuse, the hair dryer is controlled to perform different over-temperature protection strategies to dissipate heat and cool down the hair dryer, so as to avoid the hair dryer failing to start and be used due to excessive temperature and the user being burned due to excessive temperature, thereby improving the reliability and safety of the hair dryer.

[0034] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0044] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0045] The following is for reference. Figures 1-6 A control method, apparatus, hair dryer, and computer-readable storage medium for a hair dryer according to embodiments of the present invention are described.

[0046] Figure 1 This is a schematic flowchart of a hair dryer control method according to an embodiment of the present invention. Figure 1 As shown, the control method of this hair dryer includes:

[0047] Step S1: Determine if the air inlet of the hair dryer is blocked, and obtain the temperature of the temperature fuse of the hair dryer.

[0048] Specifically, during the operation of a hair dryer, changes in the airflow or pressure at the air inlet can be detected to determine if the inlet is blocked. Blockage includes, but is not limited to, complete blockage (i.e., the air inlet is completely blocked) or partial blockage (i.e., partial blockage). If the air inlet is confirmed to be blocked, the temperature of the hair dryer's thermal fuse is measured, including but not limited to obtaining the fuse temperature through a temperature sensor installed inside the hair dryer. It is understood that the thermal fuse will melt under overheating conditions to protect the hair dryer from damage caused by overheating, and obtaining the fuse temperature can determine whether the hair dryer has overheated.

[0049] Step S2: Control the hair dryer to implement different over-temperature protection strategies according to the temperature range of the thermal fuse.

[0050] Specifically, during the operation of the hair dryer, when it is determined that the air inlet of the hair dryer is blocked, different over-temperature protection strategies can be controlled for the hair dryer according to the temperature range of the temperature fuse obtained. For example, if the temperature of the temperature fuse is slightly higher than the normal range, that is, the hair dryer is in a semi-blocked state (for example, the normal range is 30-50 degrees, and now it is 50-60 degrees), the hair dryer can choose to implement a relatively mild protection strategy, including but not limited to reducing the power of the hair dryer or reducing the working time of the heating components to avoid further temperature increase. If the temperature of the temperature fuse is much higher than the normal range, that is, the hair dryer is in a fully blocked state (for example, now it is 70-80 degrees), the hair dryer can choose to implement a relatively strict protection strategy, including but not limited to immediately shutting down the power supply or stopping the heating components from working, while the blowing components continue to work for heat dissipation to prevent the hair dryer from overheating or even being damaged.

[0051] Therefore, the above control method of the hair dryer can obtain the temperature of the temperature fuse of the hair dryer when the air inlet of the hair dryer is blocked. Through the judgment result of the temperature range of the temperature fuse, different over-temperature protection strategies are controlled to cool down the hair dryer, avoiding the hair dryer from being unable to start and be used due to excessive temperature and scalding the user due to excessive temperature, thereby improving the reliability and safety of the hair dryer.

[0052] In an embodiment of the present invention, according to the temperature range of the temperature fuse, controlling the hair dryer to execute different over-temperature protection strategies includes: when it is determined that the temperature of the temperature fuse is greater than or equal to the first preset temperature and less than the second preset temperature within a continuous first preset time, controlling the hair dryer to execute the first over-temperature protection strategy.

[0053] Specifically, as Figure 2 shown, during the operation of the hair dryer, when it is determined that the air inlet of the hair dryer is blocked, the temperature of the temperature fuse is in an ascending state. At this time, the temperature of the temperature fuse can be continuously monitored within the first preset time t0. When it is determined that the temperature of the temperature fuse is greater than or equal to the first preset temperature Temp0 and less than the second preset temperature Temp1 within the continuous first preset time t0, it is determined that the hair dryer is in the first over-temperature state, and then the hair dryer can be controlled to execute the first over-temperature protection strategy. It can be understood that the first preset time t0, the first preset temperature Temp0, and the second preset temperature Temp1 can be preset values. For example, the first preset time t0 can be 10 seconds, 30 seconds, or 1 minute, etc. In a specific embodiment, 1ms < t0 < 10min; the first preset temperature Temp0 can be 70 degrees, etc.; the second preset temperature Temp1 can be 80 degrees, etc. In a specific embodiment, 0°C < (Temp0, Temp1) < 240°C.

[0054] In one embodiment of the present invention, the first over-temperature protection strategy includes: controlling the heating element of the hair dryer to turn off, and controlling the blowing element of the hair dryer to keep running.

[0055] Specifically, such as Figure 2 As shown, during the operation of the hair dryer, if the air inlet is determined to be blocked, and the temperature of the thermal fuse is determined to be greater than or equal to the first preset temperature Temp0 and less than the second preset temperature Temp1 for a continuous first preset time t0, the hair dryer will execute a first over-temperature protection strategy. This includes controlling the heating element of the hair dryer to shut down, while keeping the blowing element running. In other words, the hair dryer is determined to be in a partially blocked state, allowing the heating element to shut down while the blowing element remains operational. The blowing element carries cool air to dissipate heat, reducing the temperature of the thermal fuse and thus lowering the overall temperature of the hair dryer. This prevents damage to the hair dryer and burns to the user due to overheating, thereby improving the reliability and safety of the hair dryer. It is understood that the heating element includes, but is not limited to, a heating wire or heating coil; the blowing element can be a fan, including a fan and a motor, with the motor driving the fan to rotate, thus achieving airflow.

[0056] In one embodiment of the present invention, the hair dryer is controlled to perform different over-temperature protection strategies according to the temperature range of the temperature fuse. The method further includes: after the heating element of the hair dryer is turned off, when it is determined that the temperature of the temperature fuse is greater than or equal to a second preset temperature for a continuous second preset time, the hair dryer is controlled to perform a second over-temperature protection strategy.

[0057] Specifically, such as Figure 2 As shown, during the operation of the hair dryer, if the air inlet is found to be blocked, after controlling the heating element of the hair dryer to turn off, the temperature of the thermal fuse can be continuously monitored for a second preset time t1. When it is determined that the temperature of the thermal fuse is greater than or equal to the second preset temperature Temp1 for a continuous second preset time t1, the hair dryer is determined to be in a second over-temperature state, and the hair dryer can be controlled to execute the second over-temperature protection strategy. It is understood that the second preset time t1 can be a pre-set value, such as 10 seconds, 30 seconds, or 1 minute. In a specific embodiment, 1ms is used. <t1<10min。

[0058] In one embodiment of the present invention, the second over-temperature protection strategy includes: controlling the blower component of the hair dryer to shut down.

[0059] Specifically, such as Figure 2As shown, during the operation of the hair dryer, if the air inlet of the hair dryer is found to be blocked, and the temperature of the thermal fuse is determined to be greater than or equal to the second preset temperature Temp1 within a continuous second preset time t1, the hair dryer is controlled to execute a second over-temperature protection strategy. This includes controlling the blowing component of the hair dryer to shut down, i.e., determining that the hair dryer is in a completely blocked state. At this time, the blowing component of the hair dryer is controlled to shut down, and the hair dryer motor stops running, further reducing the workload of the hair dryer. At this time, both the heating component and the blowing component of the hair dryer stop operating, i.e., the hair dryer stops, thereby preventing the temperature from continuing to rise, avoiding damage to the hair dryer due to excessive temperature, and preventing burns to the user due to excessive temperature, thereby improving the reliability and safety of the hair dryer.

[0060] In one embodiment of the present invention, after controlling the blower's blowing component to turn off, the method further includes: outputting a first preset alarm signal.

[0061] Specifically, during the operation of the hair dryer, after confirming that the hair dryer is in a fully blocked state and controlling the hair dryer's blowing components to shut down, a first preset alarm signal can be output. Specifically, the first preset alarm signal can be an audible signal and / or a visual signal, such as a buzzer and / or an LED (Light-Emitting Diode) indicator light. The buzzer can emit an audible signal at a set frequency, such as a continuous buzzer. The LED indicator light can emit a light signal of a set color and / or a set frequency, such as a continuously flashing red LED. The first preset alarm signal is used to instruct the hair dryer to stop.

[0062] In one embodiment of the present invention, after controlling the blower component of the hair dryer to turn off, the method further includes: responding to a command to restart the hair dryer, controlling the blower component to turn on again to restart the hair dryer; after restarting the hair dryer, obtaining the current temperature of the thermal fuse; when it is determined that the current temperature of the thermal fuse is less than the set temperature corresponding to the hair dryer in the current working mode, controlling the heating component to remain on; or, when it is determined that the current temperature of the thermal fuse is greater than or equal to the set temperature corresponding to the hair dryer in the current working mode, controlling the heating component to remain off until the current temperature of the thermal fuse is less than the set temperature corresponding to the hair dryer in the current working mode, controlling the heating component to turn on.

[0063] Specifically, such as Figure 2As shown, during the operation of the hair dryer, after the blower's airflow component is turned off, if a restart command is received, the hair dryer will respond to the restart command by turning the airflow component back on to restart the hair dryer. This means the hair dryer can be restarted at any time after a protective shutdown is triggered. After restarting the hair dryer, the current temperature of the thermal fuse is monitored in real time and compared with the set temperature of the hair dryer in the current operating mode to determine if the conditions for turning the heating element on or off are met. Specifically, if the current temperature of the thermal fuse is lower than the set temperature of the hair dryer in the current operating mode, the heating element of the hair dryer can be kept on for heating. If the current temperature of the thermal fuse is greater than or equal to the set temperature of the hair dryer in the current operating mode, the heating element of the hair dryer can be kept off while the hair dryer continues to dissipate heat until the current temperature of the thermal fuse is lower than the set temperature of the hair dryer in the current operating mode, at which point the heating element of the hair dryer is turned on.

[0064] In summary, by setting the first over-temperature protection strategy, it can be ensured that when the heating element of the hair dryer is turned off, the temperature of the thermal fuse will not instantly rise above the second preset temperature (Temp2) and blow the thermal fuse. By setting the second over-temperature protection strategy, if the temperature of the thermal fuse remains too high, the hair dryer motor will stop running, and the hair dryer will shut down, ensuring that the hair dryer casing will not overheat and burn the user. Moreover, after triggering the protection shutdown, it can be restarted at any time, preventing the hair dryer from being unusable for an extended period due to overheating. While maintaining a good user experience, it avoids the problems of damage to the hair dryer due to overheating and burns to the user, thereby improving the reliability and safety of the hair dryer.

[0065] In one embodiment of the present invention, after obtaining the temperature of the thermal fuse of the hair dryer, the method further includes: obtaining the current working mode of the hair dryer; and controlling the operating power of the heating element according to the working mode.

[0066] Specifically, during the operation of the hair dryer, after obtaining the temperature of the thermal fuse, the system can also determine the current operating mode of the hair dryer, and then control the operating power of the heating element based on this mode. For example, if the hair dryer is in high-power mode, the power of the heating element can be reduced to prevent excessive heat buildup. Conversely, if the hair dryer is in low-power mode, the power of the heating element can be increased to meet the user's needs.

[0067] In one embodiment of the present invention, controlling the operating power of the thermal fuse according to the working mode includes: determining a reference operating power, an upper limit value, and a lower limit value of the heating component corresponding to the working mode; controlling the heating component to operate according to the reference operating power, and correcting the operating power of the heating component during the process of controlling the heating component to operate according to the reference operating power, so that the operating power of the heating component is maintained between the upper limit value and the lower limit value, wherein the difference between the upper limit value and the lower limit value is less than a preset value.

[0068] Specifically, combined Figure 3 and Figure 4 As shown, during the operation of the hair dryer, the operating power of the temperature fuse can be controlled according to the working mode to ensure that the heating element can quickly adjust its power when the hair dryer switches working modes, reducing power fluctuations. Specifically, the baseline operating power, upper limit, and lower limit of the heating element of the hair dryer in different working modes can be determined first. The baseline operating power of the heating element is understood to be the basic operating power that the heating element should have in different working modes, that is, the power required for the hair dryer to operate normally in different modes. Then, the heating element can be controlled to operate at a reference operating power. During the process of controlling the heating element to operate at the reference operating power, the operating power of the heating element is corrected to keep the operating power between the upper and lower limits of the operating power. It can be understood that setting the upper and lower limits of the operating power is to correct the operating power of the heating element. That is, during the process of controlling the heating element to operate at the reference operating power, the operating power of the heating element can be corrected by comparing the difference between the actual operating power and the reference operating power. As a result, the operating power of the heating element will fluctuate slowly between the upper and lower limits of the operating power, and eventually stabilize between the upper and lower limits. Since the difference between the upper and lower limits of the operating power is less than the preset value, that is, the range defined by the two is small, the operating power of the heating element can be stably controlled within a certain range, thereby solving the problem of disordered operating power of the heating element.

[0069] In one embodiment of the present invention, determining the reference operating power, upper limit of operating power, and lower limit of operating power of the heating component corresponding to the operating mode includes: obtaining the reference operating power, upper limit of operating power, and lower limit of operating power of the heating component corresponding to the operating mode from a preset working mode and power parameter correspondence lookup table, wherein the preset working mode and power parameter correspondence lookup table includes multiple working modes and the reference operating power, upper limit of operating power, and lower limit of operating power corresponding to each working mode.

[0070] Specifically, during the operation of the hair dryer, the reference operating power, upper limit operating power, and lower limit operating power of the heating element corresponding to a given operating mode can be obtained from a preset lookup table of operating modes and power parameters. Specifically, the preset lookup table stores multiple operating modes and their corresponding reference operating power, upper limit operating power, and lower limit operating power values. When the hair dryer is in operation, the operating power of the temperature fuse can be controlled according to the operating mode; that is, by consulting the preset lookup table, the reference operating power, upper limit operating power, and lower limit operating power value of the heating element corresponding to that operating mode can be found. The preset lookup table includes multiple operating modes and their corresponding reference operating power, upper limit operating power, and lower limit operating power values.

[0071] In a specific embodiment, an array of arr0*arr1 can be set as the signal for the heating element to drop signals. That is, there are 0 groups, each with 1 level signal value. Each time, the signal shifts to the next level signal value upon zero crossing. Each level signal value corresponds to a power value. Based on this, a lookup table of the correspondence between operating modes and power parameters can be constructed. This allows for more refined control of the heating element's on / off state, resulting in more precise and stable power control. When switching modes, the heating element can be driven according to the set baseline operating power value. That is, the operating power of the heating element can quickly rise to the baseline operating power value, and then the operating power of the heating element will gradually fluctuate between the upper and lower limits. Because the difference between the upper and lower limits is small, the operating power of the heating element can gradually stabilize between the upper and lower limits. Where 1 < (arr0, arr1) < 1000. It can be understood that signal dropping controls the output voltage by controlling the input current waveform of the thyristor, generally used for AC regulation. In waveform loss control, the thyristor only conducts when the input voltage is in the positive half-cycle, and the output voltage also only takes the positive half-cycle value, which is suitable for situations where only the positive half-cycle output is needed.

[0072] In one embodiment of the present invention, the operating power of the heating component is corrected by: when the temperature of the thermal fuse is lower than the set temperature in the working mode, controlling the operating power of the heating component to increase until the temperature of the thermal fuse reaches the set temperature in the working mode; when the temperature of the thermal fuse is higher than the set temperature in the working mode, controlling the operating power of the heating component to decrease until the temperature of the thermal fuse reaches the set temperature in the working mode; and when the temperature of the thermal fuse is equal to the set temperature in the working mode, controlling the operating power of the heating component to remain unchanged.

[0073] Specifically, combined Figure 3 and Figure 4As shown, during the correction of the heating element's operating power, the temperature of the thermal fuse can be acquired in real time. The operating power of the heating element is controlled based on the thermal fuse's temperature. Specifically, when the thermal fuse's temperature is lower than the set temperature corresponding to the hair dryer's current operating mode, the operating power of the heating element can be increased to raise the thermal fuse's temperature until the set temperature is reached. When the thermal fuse's temperature is higher than the set temperature corresponding to the hair dryer's current operating mode, the operating power of the heating element can be decreased to lower the thermal fuse's temperature until the set temperature is reached. When the thermal fuse's temperature is equal to the set temperature corresponding to the hair dryer's current operating mode, the operating power of the heating element can be kept constant. In summary, controlling the heating element's operating power based on the thermal fuse's temperature can prevent temperature instability caused by excessively rapid temperature drops or rises.

[0074] In one embodiment of the present invention, during the process of increasing the operating power of the heating component, if the operating power of the heating component increases to the upper limit of the operating power and the temperature of the thermal fuse does not reach the set temperature in the working mode, the heating component is controlled to continue operating according to the upper limit of the operating power until the temperature of the thermal fuse reaches the set temperature in the working mode.

[0075] Specifically, combined Figure 3 and Figure 4 As shown, during the process of increasing the operating power of the heating element, when the temperature of the thermal fuse has not reached the set temperature of the current working mode of the hair dryer, the operating power of the heating element continues to increase until it reaches the upper limit of the operating power of the heating element. The heating continues at the upper limit of the operating power, thereby ensuring that the operating power of the heating element does not exceed the range and the temperature of the thermal fuse slowly rises until the temperature of the thermal fuse reaches the set temperature of the working mode.

[0076] In one embodiment of the present invention, during the process of controlling the reduction of the operating power of the heating component, if the operating power of the heating component is reduced to the lower limit of the operating power and the temperature of the thermal fuse has not reached the set temperature in the working mode, the heating component is controlled to continue operating according to the lower limit of the operating power until the temperature of the thermal fuse reaches the set temperature in the working mode.

[0077] Specifically, combined Figure 3 and Figure 4As shown, during the process of reducing the operating power of the heating element, if the temperature of the thermal fuse still does not reach the set temperature of the current working mode of the hair dryer after the operating power of the heating element is reduced to the lower limit of the operating power, the heating element will continue to operate at the lower limit of the operating power to cool down, thereby ensuring that the operating power of the heating element does not exceed the range and the temperature of the thermal fuse gradually decreases until the temperature of the thermal fuse reaches the set temperature of the working mode.

[0078] In one embodiment of the present invention, the control method of the hair dryer further includes: determining whether the temperature fuse is in a faulty state; if so, controlling the hair dryer to stop and outputting a second alarm signal.

[0079] Specifically, during the operation of the hair dryer, the temperature value of the thermal fuse can be monitored in real time. Based on the obtained temperature value, it can be determined whether the thermal fuse is faulty. If a fault is detected, the hair dryer is stopped, and a second alarm signal is output. This second preset alarm signal can be an audible signal and / or a visual signal, such as a buzzer and / or an LED indicator. The buzzer can emit an audible signal at a set frequency (different from the frequency of the first preset alarm signal), and the LED indicator can emit a visual signal of a set color (different from the color of the first preset alarm signal) and / or at a set frequency (different from the frequency of the first preset alarm signal). The second preset alarm signal indicates that the hair dryer's thermal fuse is faulty, such as an open circuit or short circuit.

[0080] In one embodiment of the present invention, after controlling the hair dryer to stop and outputting a second alarm signal, the method further includes: responding to the instruction to restart the hair dryer, controlling the hair dryer to restart, and determining whether the temperature fuse is still in a fault state after restarting; if so, controlling the hair dryer to stop and keeping it in a power-off disabled state.

[0081] Specifically, after controlling the hair dryer to stop and outputting the second alarm signal, if a command to restart the hair dryer is received, the system responds to the command by controlling the hair dryer to restart and continuously monitors the temperature value of the thermal fuse in real time. Based on the obtained temperature value of the thermal fuse, the system determines whether the thermal fuse is still in a faulty state. If the thermal fuse is still in a faulty state after restarting, the system controls the hair dryer to stop immediately and keep it in a power-off disabled state to prevent further damage or other safety problems caused by restarting the hair dryer if the thermal fuse fault has not been repaired.

[0082] In one embodiment of the present invention, the fault state includes: open circuit state or short circuit state. Determining whether the thermal fuse is in a fault state includes: when it is determined that the temperature of the thermal fuse is greater than or equal to a third preset temperature for a continuous third preset time, the thermal fuse is determined to be in an open circuit state; when it is determined that the temperature of the thermal fuse is less than a fourth preset temperature for a continuous fourth preset time, the thermal fuse is determined to be in a short circuit state.

[0083] Specifically, such as Figure 5 As shown, the hair dryer's fault states include open circuit and short circuit states. Specifically, during the hair dryer's operation, the temperature of the thermal fuse can be monitored in real time. When the temperature of the thermal fuse is greater than or equal to the third preset temperature Temp2 within a third preset time t2, the thermal fuse is determined to be in an open circuit state, meaning the hair dryer will stop due to a fault. If the thermal fuse remains in an open circuit state when the hair dryer is restarted, the hair dryer will not be used again, thus preventing the hair dryer from blowing only cold air upon restarting. This also allows for the identification of the hair dryer's fault location and timely repair. Furthermore, when the temperature of the thermal fuse is determined to be less than the fourth preset temperature Temp3 within a fourth preset time t3, the thermal fuse is determined to be in a short circuit state, meaning the hair dryer will stop due to a fault. If the thermal fuse remains in a short circuit state when the hair dryer is restarted, the hair dryer will not be used again, thus preventing the hair dryer from blowing hot air upon restarting, which could cause the thermal fuse temperature to rise continuously and burn the user, improving the hair dryer's safety and reliability. This also allows for the identification of the hair dryer's fault location and timely repair.

[0084] In a specific embodiment, 1ms <t2<10min,1ms<t3<10min,-50℃<Temp2<200℃,-50℃<Temp3<200℃。

[0085] In one embodiment of the present invention, whether the air inlet of the hair dryer is blocked is determined based on the air pressure at the air inlet of the hair dryer and the rate of temperature change of the thermal fuse.

[0086] Specifically, during the operation of a hair dryer, the blockage of the air inlet can be determined by observing the air pressure at the inlet and the rate of temperature change of the thermal fuse. When the air inlet is blocked, the airflow decreases, leading to lower air pressure. This reduced airflow slows down the heat dissipation of the thermal fuse, causing its temperature to rise rapidly—that is, the rate of temperature change increases. Therefore, the blockage of the air inlet can be determined based on the air pressure at the inlet and the rate of temperature change of the thermal fuse. Furthermore, the larger the blockage area, the lower the air pressure at the inlet, and the higher the rate of temperature change of the thermal fuse. Therefore, the degree of blockage can be further determined by observing the magnitude of the air pressure and the rate of temperature change. For example, when the air pressure at the air inlet is less than or equal to the first preset pressure, and the temperature change rate of the thermal fuse is greater than the first preset rate, the air inlet is determined to be partially blocked (i.e., half-blocked); when the air pressure at the air inlet is less than or equal to the second preset pressure, and the temperature change rate of the thermal fuse is greater than the second preset rate, the air inlet is determined to be completely blocked (i.e., fully blocked). Here, the first preset pressure is greater than the second preset pressure, and the first preset rate is less than the second preset rate. It can be understood that the first preset pressure, the second preset pressure, and the second preset rate are values ​​preset according to factors such as different hair dryer types or models.

[0087] In summary, the above-described hair dryer control method, when the air inlet is blocked, can obtain the temperature of the hair dryer's thermal fuse. By judging the temperature range of the thermal fuse, the method controls the hair dryer to implement different overheat protection strategies to dissipate heat and cool down the hair dryer, preventing the hair dryer from failing to start or be used due to excessive heat, and avoiding burns to the user. This improves the reliability and safety of the hair dryer. Furthermore, the operating power of the heating element is controlled based on the temperature of the thermal fuse, ensuring that the operating power of the heating element is stably controlled within a certain range. This solves the problem of erratic operating power of the heating element and avoids temperature instability caused by excessively rapid temperature drops or rises. Finally, the addition of open-circuit and short-circuit protection for the thermal fuse prevents the hair dryer from blowing only cold or hot air, thus avoiding the risk of burns to the user. This provides a better user experience while improving the reliability and safety of the hair dryer.

[0088] Figure 6 This is a schematic diagram of the structure of a hair dryer control device 10 according to an embodiment of the present invention. Figure 6 As shown, the control device 10 of the hair dryer includes: an acquisition module 20 and a control module 30.

[0089] Specifically, the acquisition module 20 is used to acquire the temperature of the temperature fuse of the hair dryer when it is determined that the air inlet of the hair dryer is blocked.

[0099] In one embodiment of the present invention, the control module 30 determines the reference operating power, upper limit of operating power, and lower limit of operating power of the heating component corresponding to the operating mode, including: querying the reference operating power, upper limit of operating power, and lower limit of operating power of the heating component corresponding to the operating mode from a preset working mode and power parameter correspondence lookup table, wherein the preset working mode and power parameter correspondence lookup table includes multiple working modes and the reference operating power, upper limit of operating power, and lower limit of operating power corresponding to each working mode.

[0100] In one embodiment of the present invention, the control module 30 corrects the operating power of the heating element by: increasing the operating power of the heating element when the temperature of the thermal fuse is lower than the set temperature in the working mode, until the temperature of the thermal fuse reaches the set temperature in the working mode; decreasing the operating power of the heating element when the temperature of the thermal fuse is higher than the set temperature in the working mode, until the temperature of the thermal fuse reaches the set temperature in the working mode; and keeping the operating power of the heating element unchanged when the temperature of the thermal fuse is equal to the set temperature in the working mode.

[0101] In one embodiment of the present invention, during the process of increasing the operating power of the heating component, the control module 30 is further configured to: if the operating power of the heating component increases to the upper limit of the operating power and the temperature of the thermal fuse does not reach the set temperature in the working mode, then control the heating component to continue operating according to the upper limit of the operating power until the temperature of the thermal fuse reaches the set temperature in the working mode.

[0105] In one embodiment of the present invention, the control module 30 is used to determine whether the air inlet of the hair dryer is blocked based on the air pressure at the air inlet of the hair dryer and the temperature change rate of the thermal fuse.

[0106] In one embodiment of the present invention, after controlling the hair dryer to stop and outputting a second alarm signal, the control module 30 is further configured to: respond to the instruction to restart the hair dryer, control the hair dryer to restart, and determine whether the temperature fuse is still in a fault state after restarting; if so, control the hair dryer to stop and keep it in a power-off disabled state.

[0107] According to the hair dryer device 10 of the present invention, when the air inlet of the hair dryer is blocked, the acquisition module 20 can acquire the temperature of the thermal fuse of the hair dryer. By judging the temperature range of the thermal fuse by the control module 30, the hair dryer can be controlled to implement different over-temperature protection strategies to dissipate heat and cool down the hair dryer, so as to avoid the hair dryer failing to start and be used due to excessive temperature, and to avoid the user being burned by excessive temperature, thereby improving the reliability and safety of the hair dryer.

Finally, the addition of open circuit and short circuit protection of the thermal fuse can prevent the hair dryer from blowing only cold air or hot air, thereby avoiding the risk of user being burned. While bringing a better user experience, the reliability and safety of the hair dryer are improved.
