[0002] The hair dryer can provide cold air or hot air according to the needs of the user, and can help the user dry his hair or other items after washing, which brings great convenience to people. At present, in order to prevent the hair floating in the air from entering the hair dryer, a filter is set at the air inlet of the hair dryer.

[0069] In the description of the embodiments of the present invention, 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, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations on the embodiments of the present invention.

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.

[0073] In the related art, as the hair dryer is used for a longer period of time or is affected by the air environment, more hair or dust will gradually adhere to the filter. These adhesions will reduce the air circulation capacity of the filter, thereby causing the hair dryer to be used abnormally or even cause a high-temperature fire. It is difficult for users to determine whether the filter is blocked or needs to be cleaned based on their own judgment.

[0074] According to the first aspect of the present invention, the electric hair dryer is provided. Figures 1 to 3 , including a housing 100, an electric fan assembly, an electric heating assembly 16, a circuit board 11, a filter 21, a status detection assembly and a filter blockage prompt assembly.

[0075] A cavity is formed in the housing 100, and an air inlet 101 and an air outlet 102 connected to the cavity are provided on the housing 100. The housing 100 includes a handle and a wind tube, the handle is mounted on the outer wall of the wind tube, and the wind tube is provided with an air outlet 102 at one end.

[0076] In some embodiments, the air inlet 101 is disposed on a side of the air cylinder away from the air outlet 102 , and the air flows from one end of the air cylinder to the other end, and is blown out along the air outlet 102 after being heated inside the air cylinder.

[0077] In other embodiments, the air inlet 101 is provided on the handle, and an air cavity is formed inside the handle, which is connected to the cavity in the wind tube, and the air flows along the handle to the wind tube, and then flows out through the wind tube's air outlet 102. In this case, the side of the wind tube away from the air outlet 102 is an end plate, and a control button or a prompt component can be provided on the end plate.

[0078] See also Figures 1 to 3 In the embodiment of the present invention, the air inlet 101 is arranged on the handle, and the control button or the prompt component can be arranged on the handle or at the tail of the hair dryer.

[0079] The electric fan assembly, the electric heating assembly 16 and the circuit board 11 are all arranged in the housing 100, and the electric fan assembly and the electric heating assembly 16 are electrically connected to the circuit board 11. The electric fan assembly includes a motor 18 and a blade 19 arranged on the rotating shaft of the motor 18, and the blade 19 is located on the side of the motor 18 close to the air inlet 101. The air from the air inlet 101 will cool down the motor 18, thereby improving the stability of the motor 18 when working. The electric heating assembly 16 includes an electric heating plate or an electric heating wire, and the electric heating assembly 16 is arranged in the air duct near the air outlet 102. The air from the air inlet 101 is accelerated at the electric fan assembly, and then the temperature is changed at the electric heating assembly 16.

[0080] A filter 21 is provided at the air inlet 101 of the shell 100. The filter 21 can filter the air flowing through the air inlet 101 and block hair or fine debris in the air outside the air inlet 101, thereby preventing debris from accumulating in the shell 100 and preventing debris from contacting the high-temperature electric heating component 16 and then burning, thereby improving the safety of the hair dryer.

[0081] The state detection component is disposed in the housing 100 and is electrically connected to the circuit board 11. The state detection component can be used to detect the real-time operating parameters of the hair dryer. The state detection component can be a newly set detection element or an existing detection element.

[0082] It should be noted that when the filter 21 is blocked, the air flow rate of the hair dryer will decrease, which will bring about changes in a series of operating parameters, such as the speed of the motor 18, the temperature of the motor 18, the current of the motor 18, and the air outlet temperature of the hair dryer. The state detection component can detect the real-time operating parameters of the hair dryer, and the flow state of the filter 21 can be determined based on the real-time operating parameters and the pre-acquired set operating conditions. The filter blockage prompt component is electrically connected to the circuit board 11, and can issue a prompt message when the flow state of the filter 21 is in a blocked state.

[0083] In some embodiments, the filter blockage prompt component includes a constant temperature mode light 121, a hot air mode light 122, a cold air mode light 123 and a circulation mode light 124, etc. The filter blockage prompt component does not separately set an additional light group, but controls the constant temperature mode light 121, the hot air mode light 122, the cold air mode light 123 and the circulation mode light 124 to flash simultaneously or in a certain pattern, so as to send a filter blockage prompt information to the user.

[0084] In some embodiments, the filter blockage prompt component also includes a display screen or a speaker component, etc., which can directly convey the flow status of the filter 21 to the user, and the flow status includes a blocked state and an unblocked state.

[0085] When the hair dryer provided according to the embodiment of the present invention is in operation, when the filter 21 is blocked, the air flow rate of the hair dryer will be reduced, which will bring about changes in a series of operating parameters, such as the speed of the motor 18, the temperature of the motor 18, the current of the motor 18, and the air outlet temperature, etc. The state detection component can detect the real-time operating parameters of the hair dryer, and the flow state of the filter 21 can be determined according to the real-time operating parameters and the pre-acquired set operating conditions. When the filter 21 is in a blocked state, a prompt message is issued through the filter blocking prompt component to remind the user to replace or clean the filter 21 in time, so as to avoid high-temperature fire of the circuit or electronic components caused by the blockage of the filter 21, thereby improving the safety of the hair dryer. The present invention helps users to judge whether the filter 21 is blocked through scientific and rigorous data, and clean or replace the filter 21 in time when it is blocked.

[0086] It should be noted that the blocked state of the filter 21 is not a completely blocked state, but a state that has a greater impact on the air circulation capacity. At this time, the circuits and electronic components in the hair dryer have certain safety risks. The blocked state should be determined in time to eliminate the impact of the filter 21 blockage on the hair dryer as soon as possible.

[0087] In some embodiments, the state detection component includes a motor temperature sensor 20 , which is disposed in the housing and connected to the outer side wall of the motor.

[0088] See also Figure 1 When the filter 21 is blocked, the air circulation capacity of the air inlet 101 decreases, and the air flowing through the motor 18 per unit time is less, so the heat exchange efficiency decreases. The heat generated by the motor 18 when working cannot be discharged in time, and the real-time motor temperature will be higher than the rated temperature of the corresponding set gear. At this time, the real-time motor temperature can be compared with the pre-stored rated temperature to determine whether the circulation state of the filter 21 is in a blocked state.

[0089] In some embodiments, the state detection component includes a speed detection element, which is disposed in the housing 100 and electrically connected to the motor 18 of the electric blower assembly. The speed detection element can read the speed of the motor 18 by frequency measurement or period measurement.

[0090] See also Figure 1 When the filter 21 is blocked, the air circulation capacity of the air inlet 101 decreases, and the air flowing through the motor 18 per unit time is less, so the air resistance to the blade 19 is reduced, and the real-time motor speed of the motor 18 at the set gear will be higher than the rated speed. At this time, the real-time motor speed can be compared with the pre-stored rated speed to determine whether the circulation state of the filter 21 is in a blocked state.

[0091] In some embodiments, the state detection component includes a current detection element, which can be an analog to digital converter (ADC). The current detection element is disposed in the housing 100 and electrically connected to the circuit board 11, and can detect the current of the motor 18 when it is working.

[0092] See also Figure 1 When the filter 21 is blocked, the air circulation capacity of the air inlet 101 decreases, the amount of air flowing through the blades 19 per unit time is less, the air resistance to the blades 19 is reduced, and the real-time operating current of the motor 18 at the set gear will be lower than the rated current. At this time, the real-time operating current can be compared with the pre-stored rated current to determine whether the circulation state of the filter 21 is in a blocked state.

[0093] In some embodiments, the state detection component includes an outlet air temperature sensor 17, which is disposed in the housing 100 and located at the air outlet 102 of the hair dryer to detect the temperature of the air heated by the electric heating component 16. In this embodiment, the outlet air temperature sensor 17 is an original electronic component of the hair dryer. The outlet air temperature sensor 17 is used to detect the state of the hair dryer and determine whether the filter 21 is blocked, which makes full use of the existing electronic components without increasing the cost of the hair dryer.

[0094] See also Figure 1 When the filter 21 is blocked, the air flow capacity of the air inlet 101 decreases, and the air flowing through the electric heating component 16 per unit time decreases, so the amount of air exchanging heat with the electric heating component 16 per unit time decreases. When the electric heating component 16 maintains the rated heating power, the air outlet temperature will increase. At this time, the real-time air outlet temperature can be compared with the pre-stored rated air outlet temperature to determine whether the air flow state of the filter 21 is blocked.

[0095] In some embodiments, the hair dryer also includes a button assembly, which includes a wind speed level button 13 and a temperature adjustment button 14, both of which are installed on the shell 100, and the wind speed level button 13 and the temperature adjustment button 14 are electrically connected to the circuit board 11.

[0096] See also Figures 1 to 3Two button holes are arranged at the handle of the housing 100, and the wind speed gear button 13 and the temperature adjustment button 14 are arranged in the two button holes in a one-to-one correspondence. The wind speed gear button 13 can adjust the gear of the hair dryer, and each gear corresponds to a rated current, a rated voltage, a rated motor temperature and a rated air outlet temperature. The temperature adjustment button 14 can adjust the air outlet temperature or the working mode of the hair dryer. For example, the air outlet temperature of the hair dryer can be adjusted from cold air to hot air at 57 degrees Celsius, and the air outlet temperature of the hair dryer can be switched between cold air mode, hot air mode, 57 degrees Celsius constant temperature mode and circulation mode. The circulation mode refers to a mode in which the hair dryer automatically switches between cold air and hot air in a cycle.

[0097] In some embodiments, the button assembly further includes a cleaning button, which is mounted on the housing 100 and electrically connected to the circuit board 11 .

[0098] The hair dryer provided in the embodiment of the present invention can detect the blockage state in time through the state detection component when the flow state of the filter 21 is abnormal, and send prompt information in time through the filter blockage prompt component. After receiving the filter blockage prompt information, the user can manually disassemble and clean the filter 21; or start the back-blowing cleaning mode through the cleaning button, that is, by controlling the motor 18 to rotate in the opposite direction, the hair dryer blows air in the opposite direction, and uses the reverse flow of air to blow out the adhesions hanging on the filter 21 along the air inlet 101. The embodiment of the present invention is provided with a cleaning button, which allows the user to actively and quickly enter the back-blowing cleaning mode, and can actively clean dust after use or after using it several times to prevent hair and other debris from adhering to the filter 21.

[0099] In some embodiments, the temperature adjustment button 14 and the cleaning button are integrated into a composite button, and the composite button has multiple touch and press modes. For example, the upper and lower parts of the temperature adjustment button 14 can be touched and pressed separately, so that the air outlet temperature of the hair dryer can be adjusted upward or downward, and the operation mode of the hair dryer can be adjusted to the adjacent previous mode or to the adjacent next mode. The temperature adjustment button 14 can also be a single button, and the mode can be adjusted once each time it is touched and pressed. When the temperature adjustment button 14 is pressed continuously, for example, a certain preset time is reached, it can be switched to the backwash cleaning mode.

[0100] Integrating the temperature adjustment button 14 and the cleaning button into a composite button reduces the structural complexity of the hair dryer and can also prevent accidental touching of the cleaning button, thereby preventing the user from randomly touching the button and blowing dust toward the user.

[0101] In some embodiments, the hair dryer further includes a negative ion generator 15, which is disposed in the housing 100 and between the air inlet 101 and the electric heating assembly 16, and the negative ion generator 15 is electrically connected to the circuit board 11. Figure 1 The negative ion generator 15 utilizes high voltage corona to increase the negative ion content in the air, thereby improving the air quality and promoting health.

[0102] In some embodiments, a controller is provided on the circuit board 11, and the controller is electrically connected to the electric fan assembly, the electric heating assembly 16, the status detection assembly and the filter blockage prompt assembly.

[0103] See also Figure 1 The controller is connected to all electronic components in the hair dryer through the circuit board 11. The controller is configured to obtain real-time operating parameters of the hair dryer, and determine the flow state of the filter 21 according to the real-time operating parameters and the pre-acquired set operating conditions; wherein the flow state includes a blocked state and an unblocked state; and when the flow state is a blocked state, a signal is sent to control the electric heating component 16 to stop running, a signal is sent to control the electric fan component to run for a first preset time, and a signal is sent to control the filter blockage prompt component to run for a second preset time; wherein the second preset time is greater than the first preset time.

[0104] According to a second aspect of the present invention, a method for controlling a hair dryer is provided, comprising the following steps:

[0105] The real-time operating parameters of the hair dryer are obtained, and the flow state of the filter is determined according to the real-time operating parameters and the pre-acquired set operating conditions; wherein the flow state includes a blocked state and an unblocked state.

[0106] It can be understood that when the filter of the hair dryer provided in the embodiment of the present invention is blocked, the air inlet flow of the hair dryer will be reduced, which will bring about changes in a series of operating parameters, such as the speed of the motor, the temperature of the motor, the current of the motor and the air outlet temperature. The status detection component can detect the real-time operating parameters of the hair dryer, and determine the flow status of the filter according to the real-time operating parameters and the pre-acquired set operating conditions.

[0107] When the flow state is a blocked state, a signal is sent to control the electric heating component to stop running, a signal is sent to control the electric fan component to run for the first preset time, and a signal is sent to control the filter blockage prompt component to run for the second preset time; wherein the second preset time is greater than the first preset time.

[0108] It is understandable that when the filter is in a blocked state, the electric heating component of the hair dryer is first controlled to stop running to prevent the temperature inside the hair dryer from further increasing, thereby reducing the risk of the hair dryer catching fire. Then, a prompt message is sent through the filter blocking prompt component to remind the user to replace or clean the filter in time to avoid high-temperature fire of circuits or electronic components caused by filter blocking, thereby improving the safety of the hair dryer.

[0109] Among them, the first preset time is used to make the electric fan component work continuously, and use natural wind to cool the electric heating component; within the second preset time, the filter blockage prompt component sends a prompt message, which increases the possibility of users realizing that the filter is blocked.

[0110] The present invention helps users to judge whether the filter is blocked through scientific and rigorous data, and clean or replace the filter in time when the filter is blocked.

[0111] It should be noted that the blocked state of the filter does not mean it is completely blocked, but it does have a greater impact on the air circulation capacity. At this time, the circuits and electronic components in the hair dryer have certain safety risks. It is necessary to determine the blocked state in time and eliminate the impact of the filter blockage on the hair dryer as soon as possible.

[0112] See also Figure 4 The control method of the hair dryer provided by the embodiment of the present invention includes the following process:

[0113] S100: Obtain the real-time operating status of the hair dryer.

[0114] S110, determining the flow state of the filter according to the real-time operating parameters and the pre-acquired set operating conditions.

[0115] S120, determining whether the flow state is a blocking state.

[0116] If not, execute step S130; if so, execute step S140.

[0117] S130, sending a signal according to the current gear position and the current mode.

[0118] S140, sending a signal to control the electric heating component to stop running, sending a signal to control the electric blower component to run for a first preset time, and sending a signal to control the filter blockage prompt component to run for a second preset time.

[0119] It can be understood that controlling the electric heating component to stop running can prevent the temperature of the hair dryer from further increasing; controlling the electric blower component to run for the first preset time can allow the fresh air to quickly lower the temperature of the electric heating component to cool the motor thermal component; controlling the filter blockage reminder component to run for the second preset time is used to remind the user that the filter is in a blocked state and needs to be replaced or cleaned.

[0120] According to one embodiment of the present invention, the real-time operating parameter is the real-time motor speed of the electric fan assembly, and the set operating condition is the rated speed corresponding to the set gear. The step of determining the flow state of the filter according to the real-time operating parameter and the pre-acquired set operating condition specifically includes:

[0121] When the real-time motor speed is greater than the rated speed, the flow state is blocked;

[0122] When the real-time motor speed is less than or equal to the rated speed, the flow state is unblocked.

[0123] It is understandable that when the filter is blocked, the air circulation capacity of the air inlet decreases, and less air flows through the motor per unit time, so the air resistance to the blades decreases. The real-time motor speed of the motor in the set gear will be higher than the rated speed. At this time, the real-time motor speed can be compared with the pre-stored rated speed to determine whether the circulation state of the filter is in a blocked state.

[0124] According to one embodiment of the present invention, the real-time operating parameter is the real-time motor temperature of the electric fan assembly, and the set operating condition is the rated temperature corresponding to the set gear. The step of determining the flow state of the filter according to the real-time operating parameter and the pre-acquired set operating condition specifically includes:

[0125] When the real-time motor temperature is greater than the rated temperature, the flow state is blocked;

[0126] When the real-time motor temperature is less than or equal to the rated temperature, the flow state is unblocked.

[0127] It is understandable that when the filter is blocked, the air circulation capacity of the air inlet decreases, and less air flows through the motor per unit time, so the heat exchange efficiency decreases. The motor cannot discharge air in time when working, and the real-time motor temperature will be higher than the rated temperature of the corresponding set gear. At this time, the real-time motor temperature can be compared with the pre-stored rated temperature to determine whether the circulation state of the filter is in a blocked state.

[0128] According to one embodiment of the present invention, the real-time operating parameter is the real-time operating flow of the motor of the electric fan assembly, and the set operating condition is the rated current corresponding to the set gear. The step of determining the flow state of the filter according to the real-time operating parameter and the pre-acquired set operating condition specifically includes:

[0129] When the real-time operating current is less than the rated current, the flow state is blocked;

[0130] When the real-time operating current is greater than or equal to the rated current, the flow state is an unblocked state.

[0131] It is understandable that when the filter is blocked, the air circulation capacity of the air inlet decreases, and less air flows through the motor per unit time. Therefore, the air resistance to the blades is reduced, and the real-time operating current of the motor at the set gear will be lower than the rated current. At this time, the real-time operating current can be compared with the pre-stored rated current to determine whether the circulation state of the filter is in a blocked state.

[0132] According to one embodiment of the present invention, the real-time operating parameter is the real-time cumulative operating time of the hair dryer, and the set operating condition is the set cumulative operating time. The step of determining the flow state of the filter according to the real-time operating parameter and the pre-acquired set operating condition specifically includes:

[0133] When the real-time cumulative running time is greater than or equal to the set cumulative running time, the flow state is blocked;

[0134] When the real-time cumulative running time is less than the set cumulative running time, the flow state is unblocked.

[0135] It is understandable that when the hair dryer runs for a long time, the filter may be blocked. Under certain temperature and humidity conditions, the set cumulative running time can be determined, and the real-time cumulative running time can be compared with the set cumulative running time to determine whether the flow state of the filter is in a blocked state.

[0136] In some embodiments, the control method of the hair dryer provided by the embodiment of the present invention further includes actively running the backflush cleaning mode, including the following steps:

[0137] In response to a trigger signal for running the cleaning mode, a duration of the trigger signal is acquired.

[0138] When the duration is greater than or equal to the third preset duration, the air outlet temperature of the hair dryer is obtained, and the temperature state of the hair dryer is determined according to the air outlet temperature and the pre-acquired cooling condition; wherein the temperature state includes an overheating state and a cooling state.

[0139] When the temperature state is in an overheated state, a signal is sent to control the electric heating component to stop running, and a signal is sent to control the electric fan component to blow forward.

[0140] When the temperature state is the cooling state, a signal is sent to control the electric hair dryer to stop running, and then a signal is sent to control the electric blower assembly to run in reverse for a fourth preset time period.

[0141] In an embodiment of the present invention, the user can actively control the hair dryer to run the cleaning mode at any time. For example, the user actively switches to the cleaning mode after using it for a period of time; or when the status detection component detects that the filter is blocked, the hair dryer sends a prompt message that the filter is blocked, and the user controls the hair dryer to enter the cleaning mode according to the prompt message.

[0142] The user generates a signal for running the cleaning mode by touching the cleaning button. In order to avoid accidentally touching the cleaning mode, when the duration of the trigger signal is set to be greater than or equal to a third preset duration, the hair dryer is controlled to formally enter the cleaning mode.

[0143] Before running the cleaning mode, make sure that the electric heating component is in a low temperature state to prevent hot air from blowing back to the circuit inside the hair dryer, and to prevent the glue layer of the circuit from falling off or melting, thereby improving the safety of the hair dryer. The temperature state of the hair dryer can be determined based on the air outlet temperature of the hair dryer and the cooling conditions obtained in advance; wherein the temperature state includes an overheating state and a cooling state. For example, if the cooling condition is 50 degrees Celsius, then when the air outlet temperature is greater than or equal to 50 degrees Celsius, the hair dryer is in an overheating state; when the air outlet temperature is less than 50 degrees Celsius, the hair dryer is in a cooling state. The cooling condition mainly takes into account the impact on the circuit structure inside the hair dryer, and the cooling condition can be determined based on the heat resistance of the circuit structure. Before starting the hair dryer for the first time, it is necessary to enter the heat resistance level of the internal circuit and determine the above cooling conditions based on the heat resistance level.

[0144] When the temperature is overheated, if the back-blowing cleaning mode is directly operated at this time, the internal circuit of the hair dryer will be damaged. Therefore, the electric heating component is first controlled to stop running, and the electric blower component is controlled to blow forward for a preset cooling time to reduce the temperature of the electric heating component by cold air.

[0145] When the temperature state is in the cooling state, running the reverse blowing mode will not affect the circuit structure in the hair dryer, so the hair dryer is controlled to stop running, and then the electric blower assembly is controlled to run in reverse for a fourth preset time, and the debris adhered to the filter is blown off by the reverse airflow, thereby improving the subsequent air circulation capacity of the filter.

[0146] In some embodiments, when the temperature state is in a cooling state, the electric blower assembly can also be controlled to blow air in reverse in a pulsed manner, and the wind speed of the hair dryer is periodically switched between a first wind speed and a second wind speed, the second wind speed is greater than the first wind speed, and the second wind speed is greater than or equal to twice the wind speed of the hair dryer's highest wind speed gear. By blowing air in reverse in a pulsed manner, the maximum wind force at the moment of reverse blowing can be increased, and at the same time, the temperature of the motor caused by the hair dryer being at the second wind speed for too long a time can be avoided, which will not affect the service life of the motor, but can obtain a short period of high wind force, thereby improving the cleaning ability of the cleaning mode.
