[0003] The traditional low-temperature starting method works by directly controlling the motor in a conventional control method (without considering the impact of the low-temperature environment, and directly applying a unique control method for control). This low-temperature starting method has a great defect. Due to the influence of the low-temperature environment, the motor gears may stick tightly during low-temperature starting, causing the machine to not work properly. That is, this low-temperature starting method may cause the motor gears to stick tightly during low-temperature starting, causing the machine to not work properly, thereby causing the low-temperature starting effect of the scalp massage equipment to be poor.

[0051] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0053] Scalp massage equipment is a comb-type device that uses an electric motor (also called a motor) to rotate and drive the gears to make the comb teeth swing to massage the scalp. However, at low temperatures, the motor gears of scalp massage equipment are tightly bonded, the resistance increases, or even stop rotating. When users turn on the device at low temperatures, the speed decreases or even stops rotating (the external manifestation is that the comb teeth swing slowly, or the user thinks that the scalp massage device is faulty or damaged), which brings a very poor experience to users.

[0054] Therefore, based on the inadequacy of the above low-temperature starting scheme, a low-temperature starting method of the present application is proposed. The solution of the embodiment of the present application is to obtain the motor temperature of the motor in the scalp massage device, as well as the motor duty cycle and actual motor speed corresponding to the gear position of the device, and then determine the motor control instruction (determine how to control the motor) based on the motor temperature and the motor duty cycle, and after determining the motor control instruction, determine the incremental duty cycle in combination with the actual motor speed (that is, the duty cycle is increased to control the temperature of the motor), and after determining the incremental duty cycle, control the motor in combination with the actual motor speed to ensure that the motor returns to a normal duty cycle, and avoid the phenomenon of the motor gear being tightly adhered during low-temperature starting, causing the motor to not work properly. That is, this low-temperature starting method can be combined with the motor temperature of the motor, as well as the motor duty cycle and actual motor speed corresponding to the gear position of the device, to comprehensively heat up the scalp massage device and control the gear position in a low-temperature environment to improve the effect of low-temperature starting of the scalp massage device.

[0055] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a device capable of realizing the above functions, a scalp massage device, etc. The following takes a scalp massage device (which can be a scalp massage device in this embodiment) as an example to illustrate this embodiment and the following embodiments.

[0056] Based on this, the present application embodiment provides a low temperature startup method, referring to Figure 1 , Figure 1 This is a schematic flow chart of the first embodiment of the low-temperature startup method of the present application.

[0057] Reference Figure 1 The present application provides a low-temperature starting method. In a first embodiment of the low-temperature starting method, the low-temperature starting method is applied to a scalp massage device. The low-temperature starting method includes:

[0058] Step S10, obtaining working information of the scalp massage device, wherein the working information includes the motor temperature of the motor in the scalp massage device, and the motor duty cycle and actual motor speed corresponding to the device gear position;

[0059] In this embodiment, in order to avoid the defect of starting the scalp massage device at low temperature, the working information of the scalp massage device when it is turned on is obtained, wherein the working information includes the motor temperature of the motor in the scalp massage device, and the motor duty cycle and the actual motor speed corresponding to the device gear. The motor temperature refers to the actual temperature value of the motor, which can be obtained by collecting the rotor or stator temperature of the motor based on the relevant temperature sensor, or the temperature of other positions, such as the temperature of the connection point connected to the motor or the temperature of the actual movement position of the scalp massage device. The motor duty cycle refers to the duty cycle for controlling the movement of the motor, such as the duty cycle of a PWM (Pulse Width Modulation) signal. The actual motor speed refers to the actual speed of the motor. The device gear refers to the gear of the scalp massage device after it is turned on, such as the low gear of the scalp massage device is the motor duty cycle A and the actual motor speed B. Then, the start-up control of the scalp massage device can be performed based on the motor temperature, and the motor duty cycle and the actual motor speed corresponding to the device gear, so as to avoid the scalp massage devices being started in the same set of starting methods, resulting in the problem of poor low-temperature start-up (at low temperatures, the motor gears are tightly bonded, the resistance increases, or even stop rotating).

[0060] Step S20, determining a motor control instruction according to the motor temperature and the motor duty cycle, and determining an incremental duty cycle according to the motor control instruction and the actual motor speed;

[0061] In this embodiment, after determining the working information of the scalp massage device, the motor control instruction, i.e., the instruction for controlling the motor, will be determined based on the motor temperature and motor duty cycle in the working information. It is worth noting that the motor control instruction at this time refers to the instruction for controlling based on the temperature value, and the instruction is not used in the entire startup process. If the motor temperature is detected and it is found to be in a normal temperature state, the motor will be directly controlled based on the motor duty cycle corresponding to the equipment gear position to complete the control process at normal temperature; on the contrary, if the motor temperature is detected and it is found to be in a low temperature state (there are relevant temperature judgment standards), the motor will be indirectly controlled based on the motor duty cycle corresponding to the equipment gear position (generally based on the gradual increase of the motor duty cycle, or the motor duty cycle is changed in a certain change situation), and the subsequent startup process is executed after the control. Because the motor duty cycle changes at low temperatures, it is necessary to control the motor based on the motor control instruction, and at the same time, it is necessary to limit the change of the motor duty cycle based on the actual motor speed to obtain an increasing duty cycle, that is, the duty cycle value to which the motor duty cycle finally changes in a low temperature environment. On the one hand, the effect of setting this value at this time is to avoid large changes in speed caused by continuously changing the motor duty cycle at low temperatures. For example, if the user turns on the scalp massage device at gear 1, but the actual induction at low temperatures is gear 5, it will cause a poor user experience. On the other hand, continuously increasing the motor duty cycle will also cause inconvenience in control, that is, the motor controller needs to continuously increase the duty cycle, which will cause a sharp increase in temperature due to the continuous increase in speed, causing heating of the scalp massage device (such as burning out of internal circuit components of the scalp massage device, melting of the material of the scalp massage device by high temperature, etc.).

[0062] Step S30, controlling the motor according to the increasing duty cycle and the actual motor speed.

[0063] In this embodiment, after the motor speed is controlled to increase to the actual motor speed corresponding to the device gear, the incremental duty cycle will be reversely controlled, because when the motor control instruction controls the motor duty cycle at this time, there is a situation where the temperature rise is affected by the increase in the duty cycle. Therefore, after the temperature rises, the incremental duty cycle at this time will bring a higher motor speed. In order to ensure the user experience and the accuracy of motor control, the incremental duty cycle needs to be reversely controlled. Among them, reverse control refers to gradually reducing the incremental duty cycle to achieve the motor speed (real-time speed) to reach the actual motor speed, and then complete the speed required by the device gear. Based on the above low-temperature startup control, the scalp massage device can increase the duty cycle at low temperatures to increase the temperature and ensure the normal operation of the motor, and return to the device gear after heating, thereby improving the effect of low-temperature startup of the scalp massage device.

[0064] In one embodiment, the entire low-temperature startup control process can be as follows: NTC (Negative Temperature Coefficient) is used as a temperature sensor to detect the ambient temperature of the motor. When it is lower than a certain set value, the motor duty cycle output is gradually increased, thereby increasing the motor control torque, and synchronously detecting the motor speed until the motor speed is basically consistent with the speed corresponding to the equipment gear position at normal temperature. When the motor starts working for a period of time, the speed gradually increases after the temperature rises. At this time, it is necessary to gradually reduce the duty cycle and detect the motor speed at the same time until it is approximately equal to the expected motor speed at normal temperature, and maintain the PWM control output. Because the motor control torque is increased at low temperatures, the influence of gear adhesion resistance is reduced, the working temperature of the motor is increased through working heat, and the working life of the motor is increased. At the same time, by detecting the ambient temperature and motor speed, the motor rotation is intelligently controlled, so that the massage comb can work normally in any environment, giving users a better experience.

[0065] In the present embodiment, a low-temperature starting method is provided, which is applied to a scalp massage device, by obtaining working information of the scalp massage device, wherein the working information includes a motor temperature of a motor in the scalp massage device, and a motor duty cycle and an actual motor speed corresponding to a gear position of the device; a motor control instruction is determined according to the motor temperature and the motor duty cycle, and an incremental duty cycle is determined according to the motor control instruction and the actual motor speed; the motor is controlled according to the incremental duty cycle and the actual motor speed. This low-temperature starting method obtains the motor temperature of the motor in the scalp massage device, and the motor duty cycle and the actual motor speed corresponding to the gear position of the device, and then determines the motor control instruction based on the motor temperature and the motor duty cycle. The motor is controlled by the actual motor speed after determining the increasing duty cycle to ensure that the motor returns to a normal duty cycle, and to avoid the phenomenon that the motor gears are tightly stuck and cannot work normally during low-temperature startup. That is, this low-temperature startup method can combine the motor temperature of the motor, the motor duty cycle and the actual motor speed corresponding to the equipment gear position, and perform comprehensive heating and gear control on the scalp massage equipment in a low-temperature environment to improve the low-temperature startup effect of the scalp massage equipment.

[0066] Further, based on the first embodiment of the present application, a second embodiment of the low temperature starting method of the present application is proposed. In this embodiment, the above step S20, the step of determining the motor control instruction according to the motor temperature and the motor duty cycle, includes:

[0067] Step S21, detecting whether the motor temperature is lower than a preset low temperature;

[0068] Step S22, if the motor temperature is lower than the preset low temperature, determining the motor control instruction according to the motor duty cycle;

[0069] Step S23, if the motor temperature is greater than or equal to the preset low temperature, determine the motor control instruction to output the motor duty cycle as a first control signal, wherein the first control signal is used to control the motor.

[0070] In the present embodiment, when determining the motor control instruction, it is mainly determined based on the motor temperature. By detecting whether the motor temperature is less than the preset low temperature, it is determined whether the scalp massage device needs to execute the low temperature start-up procedure, wherein the preset low temperature can be a low temperature value defined by the user, and the user here generally refers to the manufacturer. At this time, if it is determined that the motor temperature is less than the preset low temperature, it will be known that this is a low temperature environment, and then to execute the low temperature start-up procedure, it is necessary to determine the motor control instruction based on the motor duty cycle, that is, to determine how to use the changing motor duty cycle as the motor control instruction to heat up the scalp massage device and avoid the motor from operating at a lower speed in a low temperature environment and damaging the motor. Conversely, if it is determined that the motor temperature is greater than or equal to the preset low temperature, it will be known that this is a normal temperature environment, and the motor duty cycle will be directly used as the motor control instruction, that is, at this time, a first control signal is output based on the motor control instruction to control the motor, and the first control signal refers to a control signal whose duty cycle is the motor duty cycle. Further, reference may be made to Figure 2 , Figure 2 This is a flow chart of the low-temperature start-up method of the present application. After the scalp massage device is turned on by long pressing the button, the NTC resistor detects the operating temperature of the motor. When the operating temperature of the motor is lower than the set temperature, the subsequent low-temperature start-up process will be executed. Otherwise, when the operating temperature of the motor is not lower than the set temperature, it will be controlled according to the normal PWM duty cycle (i.e., the motor duty cycle) to ensure the diversity of motor control in the scalp massage device, and at the same time ensure the low-temperature start-up effect based on the subsequent low-temperature start-up process.

[0071] Further, the step of determining the motor control instruction according to the motor duty cycle includes:

[0072] Step S221, determining a control duty cycle corresponding to the motor duty cycle, wherein the difference between the control duty cycle and the motor duty cycle is a preset threshold;

[0073] Step S222, determining that the motor control instruction is a second control signal corresponding to the output control duty cycle, wherein the second control signal is used to control the motor and is adjusted up in sequence with a preset step size.

[0074] In this embodiment, when it is determined that low-temperature startup control is required, the motor duty cycle will be processed, and the processed motor duty cycle will be used as the motor control instruction. The processing flow is to determine the control duty cycle corresponding to the motor duty cycle, wherein the difference between the control duty cycle and the motor duty cycle is a preset threshold value, and the preset threshold value can be a positive value or a negative value. Taking a positive value as an example, the motor duty cycle is A1, and the preset threshold value is 5, then the control duty cycle is A1+5. At this time, the control duty cycle can be used as the second control signal to control the motor based on the second control signal, wherein the second control signal needs to be adjusted up in sequence based on the control duty cycle with a preset increase step size. If the preset increase step size is 0.5, the duty cycle of the motor output for this time is A1+5, and the duty cycle of the motor output for the next time is A1+5.5, so as to control the motor based on the changed duty cycle, and ensure low-temperature startup by increasing the control torque of the motor. It is worth noting that the time interval for changing the motor duty cycle can be defined according to the actual situation, and the preset increase step size can also be a multiplication method. For example, the current duty cycle is M times the previous duty cycle, which mainly increases the duty cycle, but the method of increasing is not limited.

[0075] Further, based on the first embodiment and / or the second embodiment of the present application, a third embodiment of the low temperature starting method of the present application is proposed. In this embodiment, the step of determining the increasing duty cycle according to the motor control instruction and the actual motor speed includes:

[0076] Step S24, obtaining a first real-time motor speed of the motor under the control of the motor control instruction, and detecting whether the first real-time motor speed is less than the actual motor speed;

[0077] Step S25, if the first real-time motor speed is less than the actual motor speed, executing the step of acquiring the first real-time motor speed of the motor under the control of the motor control instruction;

[0078] Step S26: If the first real-time motor speed is greater than or equal to the actual motor speed, a first target duty cycle corresponding to the first real-time motor speed is determined as the incremental duty cycle.

[0079] In this embodiment, after the motor control instruction is determined, the motor will be controlled based on the motor control instruction. For example, at normal temperature, the step of determining the increasing duty cycle based on the motor control instruction and the actual motor speed will not be continued. Only under low temperature control will the first real-time motor speed of the motor under the control of the motor control instruction be obtained, and then it will be checked whether the first real-time motor speed at this time reaches the actual motor speed corresponding to the equipment gear position, wherein the first real-time motor speed refers to the speed value of the motor under the control of the motor control instruction. When the first real-time motor speed is less than the actual motor speed, the step of obtaining the first real-time motor speed of the motor under the control of the motor control instruction is continued, that is, the duty cycle of the motor control instruction continues to change at this time, and the first real-time motor speed of the motor is obtained after the change. It is worth noting that an acquisition duration can be set at this time, and the duration can be consistent with the duty cycle change duration of the motor control instruction, so that the first real-time motor speed of the motor can be obtained for judgment after each change in the duty cycle of the motor control instruction. Conversely, when the first real-time motor speed is greater than or equal to the actual motor speed, the first target duty cycle corresponding to the first real-time motor speed is directly determined as the incremental duty cycle. The first target duty cycle refers to the duty cycle value when the first real-time motor speed is greater than or equal to the actual motor speed. Please refer to Figure 2 , the duty cycle output is gradually increased through the motor control instruction, such as Dn+1=Dn*1.05, n=0, 1, 2...; thereby increasing the control torque of the motor, and synchronously detecting the first real-time motor speed of the motor at the same time, until the first real-time motor speed of the motor is basically consistent with the speed at normal temperature (mainly the actual motor speed corresponding to the equipment gear position at normal temperature), the duty cycle at this time is determined as the increasing duty cycle, and control is performed based on the increasing duty cycle at this time. On the one hand, it can ensure the normal heating and control of the scalp massage equipment, and at the same time ensure the user experience (the speed can ensure the actual motor speed corresponding to the equipment gear position at normal temperature).

[0080] In one embodiment, after the step of determining the motor control instruction according to the motor temperature and the motor duty cycle, the method further comprises:

[0081] Step S201, when the motor control instruction is the second control signal, obtaining a first real-time temperature value of the motor in real time, and detecting whether the first real-time temperature value is greater than a preset standard temperature;

[0082] Step S202: If the first real-time temperature value is greater than the preset standard temperature, a second target duty cycle corresponding to the first real-time temperature value is determined, and the second target duty cycle is used as the incremental duty cycle.

[0083] In this embodiment, after determining the motor control instruction, the user experience can be guaranteed by the rotation speed, and the scalp massage device can also be directly controlled based on the temperature. When the motor control instruction is the second control signal, that is, it is a low-temperature control process, by real-time acquisition of the first real-time temperature value of the motor under the control of the motor control instruction, and detecting whether the first real-time temperature value is greater than the preset standard temperature, when the first real-time temperature value is greater than the preset standard temperature, the second target duty cycle corresponding to the first real-time temperature value is determined, and the second target duty cycle is used as the incremental duty cycle. Among them, the first real-time temperature value refers to the motor temperature in the control process of the motor control instruction, the preset standard temperature refers to the user-defined motor normal temperature, and the second target duty cycle refers to the motor control duty cycle when the first real-time temperature value is greater than the preset standard temperature. That is, the motor temperature under the control of the motor control instruction is continuously monitored at this time. When the first real-time temperature value is greater than the preset standard temperature, the second target duty cycle is used as the incremental duty cycle, and the step of controlling the motor by increasing the duty cycle and the actual motor speed is directly executed, without executing the process of controlling the motor with the second target duty cycle for a period of time. Then, the motor can be controlled based on the temperature to avoid the phenomenon of motor overheating or the duty cycle that needs to be continuously controlled. It is worth noting that this process can be executed simultaneously with the step of determining the incremental duty cycle according to the motor control instruction and the actual motor speed, and the incremental duty cycle is selected to be determined first for subsequent operations to ensure the intelligence of the entire low-temperature startup.

[0084] Further, based on the first embodiment, the second embodiment and / or the third embodiment of the present application, a fourth embodiment of the low temperature starting method of the present application is proposed. In this embodiment, the step of controlling the motor according to the increasing duty cycle and the actual motor speed includes:

[0085] Step S31, determining a target duty cycle in the incremental duty cycle, obtaining a second real-time motor speed of the motor under the control of the target duty cycle, and detecting whether the second real-time motor speed is greater than the actual motor speed;

[0086] Step S32, if the second real-time motor speed is greater than the actual motor speed, updating the target duty cycle based on a preset downward adjustment step, and executing the step of acquiring the second real-time motor speed of the motor under the control of the target duty cycle based on the updated target duty cycle;

[0087] Step S33: If the second real-time motor speed is less than or equal to the actual motor speed, the motor is controlled based on the target duty cycle.

[0088] In this embodiment, after obtaining the increasing duty cycle, the motor will be controlled for a period of time based on the target duty cycle in the increasing duty cycle (which may be the first target duty cycle or the second target duty cycle mentioned above) to ensure that the motor temperature is stable, and then the second real-time motor speed of the motor under the control of the target duty cycle is obtained, and at the same time, it is detected whether the second real-time motor speed is greater than the actual motor speed, wherein the second real-time motor speed refers to the speed of the motor under the control of the target duty cycle. If the second real-time motor speed is less than or equal to the actual motor speed, the motor is controlled based on the target duty cycle. If it is first determined that the second real-time motor speed is less than or equal to the actual motor speed, the value of the target duty cycle can be appropriately increased. On the contrary, when the second real-time motor speed is greater than the actual motor speed, that is, the actual speed is greater than the speed corresponding to the equipment gear position, the speed needs to be reduced to ensure that the scalp massage device works accurately at the speed of the equipment gear position, and then the target duty cycle is updated based on the preset downward adjustment step size, and based on the updated target duty cycle, the step of obtaining the second real-time motor speed of the motor under the control of the target duty cycle is executed, that is, after the target duty cycle is reduced by the preset downward adjustment step size, the motor is controlled, and the step of obtaining the second real-time motor speed of the motor under the control of the target duty cycle is executed. Please refer to Figure 2 , when the motor starts working at the target duty cycle for a period of time T, the speed gradually increases after the temperature rises. At this time, the duty cycle is gradually reduced, Dm+1=Dm*0.95, m=0, 1, 2..., and the second real-time motor speed of the motor is detected at the same time until it is approximately equal to the expected motor speed (that is, the actual motor speed) at normal temperature. At this time, the PWM control output is maintained. Then, through the above control method, it is finally achieved that the massage comb motor can rotate and work normally at low temperatures without getting stuck and stopping. After rotating for a period of time, when the motor temperature rises and the speed becomes larger, the control duty cycle is reduced again, so that the scalp massage device can work normally at any temperature, giving users a better user experience. Let the manufacturer's product yield be higher and reduce the risk of returns due to the inability to use scalp massage equipment at low temperatures.

[0089] Further, based on the first embodiment, the second embodiment and / or the third embodiment of the present application, a fourth embodiment of the low temperature starting method of the present application is proposed. In this embodiment, before the step of controlling the motor according to the increasing duty cycle and the actual motor speed, at least one of the following is included:

[0090] Step a, controlling the operation of the motor based on a first target duty cycle in the incremental duty cycle, and when the operation control reaches a threshold time, executing a step of controlling the motor according to the incremental duty cycle and the actual motor speed;

[0091] Step b, controlling the operation of the motor based on the first target duty cycle in the increasing duty cycle, and obtaining a second real-time temperature value during the operation control. When the second real-time temperature value is greater than the preset standard temperature, executing the step of controlling the motor according to the increasing duty cycle and the actual motor speed.

[0092] In this embodiment, before executing the step of controlling the motor by increasing the duty cycle and the actual motor speed, in order to ensure temperature stability, the motor can be operated and controlled based on the first target duty cycle in the increasing duty cycle, and when the operation control reaches the threshold time, the step of controlling the motor according to the increasing duty cycle and the actual motor speed is executed, that is, the motor is continuously controlled to work at the first target duty cycle, and the working time reaches the threshold time, and the threshold time refers to the user-defined time, such as 10S; the second real-time temperature value during the operation control can also be obtained, and when the second real-time temperature value is greater than the preset standard temperature, the step of controlling the motor according to the increasing duty cycle and the actual motor speed is executed, thereby ensuring the accuracy of temperature control, so as not to affect the use of the scalp massage device due to overheating or temperature not meeting the standard. It is worth noting that if the increasing duty cycle is the second target duty cycle, the step of controlling the motor according to the increasing duty cycle and the actual motor speed can be directly executed to ensure the diversity of low-temperature startup of the scalp massage device.

[0093] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the low-temperature startup method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0094] This application also provides a low scalp massage device, please refer to Figure 3 The scalp massage device includes a motor controller 10, and the motor controller 10 includes:

[0095] An information acquisition module A10 is used to acquire the working information of the scalp massage device, wherein the working information includes the motor temperature of the motor in the scalp massage device, and the motor duty cycle and actual motor speed corresponding to the device gear position;

[0096] A first control module A20, configured to determine a motor control instruction according to the motor temperature and the motor duty cycle, and determine an incremental duty cycle according to the motor control instruction and the actual motor speed;

[0097] The second control module A30 is used to control the motor according to the increasing duty cycle and the actual motor speed.

[0098] In one embodiment, referring to Figure 4 , Figure 4This is a schematic diagram of the internal circuit connection of the scalp massage device in the low-temperature starting method of this application, and the scalp massage device also includes:

[0099] Battery 30;

[0100] A switch circuit 40, the switch circuit 40 is connected to a switch control terminal of the motor controller 10;

[0101] A boost circuit 50, wherein an input end of the boost circuit 50 is connected to a first power supply end of the battery 30, and an output end of the boost circuit 50 is connected to a motor power supply end of the motor 20;

[0102] A voltage stabilizing circuit 60, wherein an input end of the voltage stabilizing circuit 60 is connected to a second power supply end of the battery 30, and an output end of the voltage stabilizing circuit 60 is connected to a chip power supply end of the motor controller 10;

[0103] The temperature detection circuit 70 is arranged on the motor 20, and the output end of the temperature detection circuit 70 is connected to the temperature acquisition end of the motor controller 10, wherein the motor control end of the motor controller 10 is connected to the signal control end of the motor 20, and the signal acquisition end of the motor controller 10 is connected to the signal output end of the motor 20.

[0104] In this embodiment, the battery 30 supplies power to the motor controller 10 and the motor 20. The battery 30 obtains a fixed voltage through a voltage stabilizing circuit 60 to power the motor controller 10, wherein the voltage stabilizing circuit 60 may be a commonly used voltage stabilizing chip, such as a voltage stabilizing chip that outputs +5V, etc., and the motor controller 10 may be an MCU (Microcontroller Unit) or the like; at the same time, the battery 30 obtains a fixed voltage through a boost circuit 50, such as 5V, 12V, etc. to power the motor 20, wherein the boost circuit 50 may be a commonly used boost chip. When it is necessary to control the motor to work, the switch control end of the motor controller 10 is directly controlled by the switch circuit 40. The motor controller 10 can determine whether it needs to work based on the input signal of the switch control end. The switch circuit 40 can be directly a switch. When a high level is input, it is determined that the motor needs to be controlled to work, and when a low level is input, it is determined that the motor does not need to be controlled to work. It is worth noting that the above switch circuit 40, voltage stabilizing circuit 60 and boost circuit 50 can all use commonly used related circuits, which are not limited here.

The motor controller 10 outputs a PWM signal to control the rotation of the motor. At the same time, after the motor rotates, the feedback speed signal FG and the motor temperature collected by the temperature detection circuit 70 are given to the motor controller 10 for detection. The motor controller 10 determines whether the motor rotation is normal by the speed, and at the same time combines the duty cycle in the PWM signal and the actual speed actually required to realize the low-temperature start control of the scalp massage device. In combination with the motor temperature of the motor, the motor duty cycle and the actual motor speed corresponding to the gear position of the device, the scalp massage device is comprehensively heated and the gear position is controlled in a low-temperature environment to improve the effect of the low-temperature start of the scalp massage device.
