[0030] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0031] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0032] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0033] As used in the specification and appended claims of this application, the term "if" can be interpreted as "when" or "uponce" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "uponce it is determined" or "in response to determining" or "uponce [described condition or event] is detected" or "in response to detecting [described condition or event]", depending on the context.

[0034] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0035] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0036] It is understandable that the motor of the hair dryer is in a high-speed rotation state when it is working. If it is accidentally dropped or hit, the motor can easily cause a variety of fault problems:

[0037] First, a drop or collision may directly cause physical damage to the motor. There are many precision parts inside the high-speed rotating motor, such as bearings, rotors, stators, etc. These parts are prone to deformation, breakage or displacement when impacted by external forces, thus affecting the normal operation of the motor. In addition, the outer casing or fan blades of the motor may also be damaged by collision, further aggravating the failure of the motor.

[0038] Secondly, a fall or collision may also cause problems with the electrical connections inside the motor. The operation of the motor depends on the smooth flow of current, and the electrical connection points (such as terminals, coil lead wires, etc.) may loosen or break when impacted, resulting in the inability to transmit current normally, which in turn affects the normal operation of the motor.

[0039] Furthermore, falling or collision may cause the motor's internal lubrication system to fail. When the motor rotates at high speed, it needs good lubrication to reduce friction and wear. If the lubrication system is damaged by external impact, such as lubricant leakage or oil seal damage, it will increase friction between the motor's internal components, accelerate wear, and eventually cause failure.

[0040] In summary, when a hair dryer is accidentally dropped or collided, the motor is likely to fail or even be scrapped. In view of the above technical problems, the embodiment of the present application provides a hair dryer and a method for preventing accidents of the hair dryer. The technical solution of the present invention is introduced through specific embodiments below.

[0041] Embodiment 1

[0042] like Figure 1 As shown, the embodiment of the present application provides a hair dryer 1 including a motor 10, a controller 20, a sensor 30, a motor driver 40, a memory 50, and a computer program stored in the memory 50 and executable on the controller 20. The sensor 30 is configured to collect motion data of the hair dryer 1 at each moment within the current time range; the motor driver 40 is configured to drive the motor 10 to work; and the motor 10 is configured to drive the blades of the hair dryer 1 to output airflow. In general, the hair dryer 1 also includes an electric heating circuit 60, which is configured to heat the outlet airflow of the hair dryer 1.

[0043] It should be understood that in the embodiment of the present application, the controller 20 is the system control core of the entire hair dryer, and is the execution unit of all software and hardware control logic of the hair dryer. The controller 20 can specifically be an MCU (microcontroller unit, MCU). The controller 20 can also be other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASICs), field programmable gate arrays (FPGAs) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc.

[0044] The memory 50 may include a read-only memory and a random access memory, and provide instructions and data to the controller 20. The memory 50 may also include a non-volatile random access memory. The memory 50 may be a volatile memory or a non-volatile memory, or may include both volatile and non-volatile memories. Among them, the non-volatile memory may be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), or a flash memory. The volatile memory may be a random access memory (RAM), which is used as an external cache. By way of example and not limitation, many forms of RAM are available, such as static RAM (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchronous link DRAM (SLDRAM), and direct memory bus random access memory (DR RAM).

[0045] Furthermore, the hair dryer in this embodiment includes a monitoring protection mode and a normal mode when working. If the user needs to prevent accidents during the operation of the hair dryer, the user can turn on the monitoring protection mode. If there is no such need, the monitoring protection mode can be turned off so that the hair dryer can only operate in the normal mode.

[0046] When the hair dryer is working, the user turns on the monitoring protection mode of the hair dryer, and the controller 20 of the hair dryer implements the following method steps when executing the computer program, including steps S01 to S03:

[0047] Step S01: acquiring the motion data of the hair dryer at each moment collected by the sensor within the current time range;

[0048] Specifically, when the hair dryer is in the monitoring protection mode, the sensor 30 is called to collect motion data at each moment within the current time range.

[0049] In a specific implementation, the sensor 30 may be one of an acceleration sensor, a gyroscope sensor, and a gravity sensor. This embodiment takes an acceleration sensor as an example of a sensor provided to the hair dryer of the present invention.

[0050] When the hair dryer is in monitoring protection mode, the acceleration sensor continuously collects the acceleration value of the hair dryer in real time. The acceleration value includes the acceleration components of the hair dryer in the three-dimensional space coordinate system of the X-axis, Y-axis and Z-axis.

[0051] Step S02: based on each of the motion data, obtaining motion change data of the hair dryer when it works within the current time range;

[0052] Step S03: When the motion change data meets a preset range threshold condition, the hair dryer is controlled in a preset manner, and the preset range threshold condition indicates that an accident is about to occur to the hair dryer.

[0053] It is understandable that the controller can calculate the motion change data (the change of the acceleration value) within the current time range according to the motion data (acceleration value) at each moment within the current time range, and the current time range can be understood as a time range including the current moment and a few seconds before the current moment;

[0054] Then the controller determines whether the current state of the hair dryer is in a normal operating state or an abnormal state with potential accident hazards based on the motion change data. If there is an accident hazard, it is necessary to determine what kind of accident the hair dryer is about to have based on the motion change data:

[0055] Accident situation 1: When the motion change data is greater than the first threshold value A, and the duration of the motion change data being greater than the first threshold value A is greater than the first preset duration T1, it is determined that the hair dryer is about to have a collision event, and a collision event flag is triggered. Among them, the first threshold value A involved in the collision event flag of the embodiment of the present application can be understood as a collision detection threshold, and the first preset duration T1 is a collision detection duration. In the specific implementation, these first threshold values ​​A and first preset duration T1 will be tested; of course, in the later process of using the hair dryer, the user can also set the first threshold value A and the first preset duration T1 according to the needs of their own application scenarios. For example, the hair dryer is also provided with a human-computer interaction interface, and the user can set and adjust the first threshold value A and the first preset duration T1 through the human-computer interaction interface on the hair dryer.

[0056] Accident situation 2: When the motion change data is greater than the second threshold value B, and the duration of the motion change data being greater than the second threshold value B is greater than the second preset duration T2, it is determined that the hair dryer is about to fall, and a fall event flag is triggered. Among them, the second threshold value B involved in the fall event flag of the embodiment of the present application can be understood as a fall detection threshold, and the second preset duration T2 is the fall detection duration. In the specific implementation, the second threshold value B and the second preset duration T2 will be tested; of course, in the later process of using the hair dryer, the user can also set the second threshold value B and the second preset duration T2 according to the needs of their own application scenarios. For example, the hair dryer is also provided with a human-computer interaction interface, and the user can set and adjust the second threshold value B and the second preset duration T2 through the human-computer interaction interface on the hair dryer.

[0057] refer to Figure 3 If the controller of the hair dryer detects a collision event flag or a drop event flag, the hair dryer is controlled in a preset manner, for example, the motor driver is controlled to stop working, so that the motor of the hair dryer can run. If the hair dryer has a heating function turned on, the electric heating circuit is also controlled to stop working.

[0058] The beneficial effect of this embodiment is that the hair dryer obtains its motion change data within the current time range during operation, and determines whether the hair dryer is currently in a normal working state or an abnormal state based on the motion change data. If the hair dryer is in an abnormal state and the motion change data meets the preset range threshold conditions, it means that the hair dryer is about to have an accident. Finally, the hair dryer is controlled in a preset manner, and the hair dryer itself can take certain protective measures before the hair dryer officially accidentally falls or collides, thereby avoiding failures of the hair dryer motor caused by the hair dryer falling or colliding.

[0059] It should be noted that the above embodiments can be implemented in whole or in part by software, hardware, firmware or any other combination thereof. When implemented using software, the above embodiments can be implemented in whole or in part in the form of a computer program product. The computer program product includes one or more computer instructions. When the computer program instructions are loaded or executed on a hair dryer, the process or function described in the embodiment of the present application is generated in whole or in part. The computer instructions can be stored in a computer-readable storage medium, or transmitted from one computer-readable storage medium to another computer-readable storage medium. For example, the computer instructions can be transmitted from a website, hair dryer, computer, server or data center to another website, hair dryer, computer, server or data center by wired (e.g., coaxial cable, optical fiber, digital subscriber line (DSL)) or wireless (e.g., infrared, wireless, microwave, etc.) mode. The available medium can be a magnetic medium (e.g., a floppy disk, a hard disk, a tape), an optical medium (e.g., a DVD), or a semiconductor medium. The semiconductor medium can be a solid state drive (SSD).

[0060] For example, in one embodiment, Figure 4 As shown, the present invention also provides a hair dryer accident prevention system, which represents a software system, including a main control module 100, a motion data acquisition module 200, a collision detection module 310, a drop detection module 320, a motor control module 400 and a heating control module 500.

[0061] The main control module 100 is configured to control and call the motion data acquisition module 200, the collision detection module 310, the drop detection module 320, the motor control module 400 and the heating control module 500, and perform relevant calculations and processing on the obtained data;

[0062] Motion data collection module 200: configured to collect components of the hair dryer motion data in a three-dimensional space coordinate system in real time;

[0063] The collision detection module 310 is configured to perform a collision detection function to determine whether the hair dryer is about to have a collision event, or to determine whether the hair dryer has had a collision event.

[0064] The drop detection module 320 is configured to execute the drop detection function to determine whether the hair dryer is about to drop, or to determine whether the hair dryer has dropped.

[0065] The motor control module 400 is configured to control the operation of the motor.

[0066] Heating control module 500: controls the heating function.

[0067] Taking the sensor as an acceleration sensor as an example, the control process of the hair dryer accident prevention system in the monitoring protection mode of this embodiment is:

[0068] The main control module 100 calls the motion data acquisition module 200 to read the acceleration components of the XYZ axes of the real-time three-dimensional Cartesian coordinate system;

[0069] The main control module 100 calculates the change value of the acceleration and calls the collision detection module 310 and the drop detection module 320 to make a judgment:

[0070] If the acceleration change exceeds the first threshold value A and lasts for longer than the first preset time length T1, a collision event flag is triggered; if the acceleration change exceeds the second threshold value B and lasts for longer than the second preset time length T2, a fall flag is triggered.

[0071] If the collision event flag or the drop flag is triggered, the main control module 100 will control the motor control module 400 to stop the motor from working, and control the heating control module 500 to stop outputting the heating function.

[0072] If the collision event flag is not triggered or the drop flag is not triggered, the main control module 100 notifies that the hair dryer's hair dryer is working normally, and the main control module 100 will continue to call the motion data acquisition module 200 to collect the components of the hair dryer's motion data in the three-dimensional space coordinate system in real time to monitor the hair dryer's motion change data to prevent accidents.
