[0024] In addition, when describing representative embodiments, the specification may have presented the method and / or process as a specific sequence of steps. However, to the extent that the method or process does not depend on the specific order of the steps described herein, the method or process should not be limited to the specific order of steps described. As will be understood by those of ordinary skill in the art, other step sequences are possible. Therefore, the specific order of steps set forth in the specification should not be construed as a limitation on the claims. In addition, the claims directed to the method and / or process should not be limited to performing their steps in the order written, and those skilled in the art can easily understand that these orders can be varied and still remain within the spirit and scope of the embodiments of this application.

[0025] The embodiments of this application provide a control method for a back scrubber, as Figure 1 shown, including: S100: Based on the received start signal of the back scrubber, control the rotation of the scrubbing head of the back scrubber to start the scrubbing program; S102: Adjust the output power of the scrubbing head motor that drives the rotation of the scrubbing head according to the rotation resistance information received by the scrubbing head.

[0026] In this control method for a bath scrubber, upon receiving a start signal (e.g., a user pressing the on button), the bath scrubber starts, the bath scrubber program begins, and the brush head of the bath scrubber begins rotating. If the user does not adjust the gear position of the bath scrubber, the bath scrubber operates at the lowest gear position, meaning the brush head rotates at the lowest speed.

[0027] When a user's body touches the brush head of a bath scrubbing machine, its rotation is hindered. Based on the rotational resistance, the output power of the brush motor driving the brush head (the mechanical power the brush motor can output during operation, which is the product of the rotational torque output by the motor shaft and the angular velocity of the motor shaft) is adjusted to ensure the brush head rotates at an appropriate speed. Specifically, when the user's body touches the brush head of a bath scrubbing machine, the brush head experiences rotational resistance, increasing the output torque of the motor driving the brush head and the current generated by the motor. A data acquisition circuit (which can be located in the bath scrubbing machine's electronic control box) converts the increased current signal into a voltage signal. The magnitude of this current or voltage signal represents the rotational resistance experienced by the brush head. Based on the received voltage signal, the bath scrubbing machine's control device (e.g., a main control board) adjusts the PWM (Pulse Width Modulation) waveform of the drive circuit driving the brush motor, increasing the output power of the drive circuit and the brush motor, thereby maintaining or increasing the brush head's rotational speed and providing the user with a better bath scrubbing experience.

[0028] The control method of this bath scrubbing machine can automatically adjust the output power of the brush head motor that drives the brush head according to the rotational resistance information of the brush head, thereby automatically adjusting the speed of the brush head. This avoids the inconvenience caused by the manual operation of the gear adjustment button to adjust the speed of the brush head in existing bath scrubbing machines. The control method of this bath scrubbing machine can realize automatic adjustment of the brush head speed, making the bath scrubbing machine convenient to use and providing users with a better bath scrubbing experience.

[0029] In some exemplary embodiments, the control method of the bath scrubbing machine further includes: After the bath scrubbing machine is started, measure the pressure displacement of the brush head; When the rotational resistance information of the brush head is within the preset rotational resistance range and the pressing displacement of the brush head is less than the first preset displacement range, the strong cleaning mode of the bath scrubbing machine is turned on, wherein the first preset displacement range is not greater than the preset displacement range corresponding to the preset rotational resistance range (e.g., the first preset displacement range S1 = the preset displacement range corresponding to the preset rotational resistance range * K1, 0<K1≤1); When the rotational resistance information received by the brush head is within the preset rotational resistance range and the pressing displacement of the brush head is not less than the second preset displacement range, control the scrubbing machine to operate in its original state, where the second preset displacement range is not less than the first preset displacement range and not greater than the preset displacement range corresponding to the preset rotational resistance range (e.g., the second preset displacement range S2 = the preset displacement range corresponding to the preset rotational resistance range * K2, where K1 ≤ K2 ≤ 1).

[0030] The scrubbing machine may include a TOF (Time-of-flight) module. The TOF module is a sensor that measures distance using the time difference between the emitted light and the reflected light. Through the ranging function of the TOF module, the pressing displacement generated when the user's body touches the brush head and the brush head is pressed can be measured. A preset value can be made for the voltage feedback signal (the signal of the brush head motor collected by the acquisition circuit) generated under the same pressing displacement, that is, the preset rotational resistance range received by the brush head is corresponded to the preset displacement range when the brush head is pressed. Measure the pressing displacement of the user pressing the brush head under the same voltage feedback signal. When the pressing displacement of the brush head is less than the first preset displacement range (the first preset displacement range is not greater than the preset displacement range corresponding to the same voltage feedback signal (i.e., the first preset displacement range is less than or equal to the preset displacement range corresponding to the preset rotational resistance range received by the brush head), e.g., the first preset displacement range is 10%, 20%, 30% or other ratios of the corresponding preset displacement range), it indicates that the brush head can obtain a relatively large rotational friction resistance with a relatively small pressing displacement. Therefore, it can be judged that the user's skin is rough or the health condition is poor. At this time, the strong cleaning mode can be activated to enhance the cleaning strength for the user and improve the user experience. Among them, the scrubbing machine may include at least one of a shower gel application switch, an essential oil module, and a water spraying module. In the strong cleaning mode, control the scrubbing machine to perform at least one of the following operations: turn on the shower gel application switch of the scrubbing machine, turn on the essential oil application switch of the scrubbing machine, and turn on the water spray nozzle of the scrubbing machine. When performing strong cleaning using the strong cleaning mode, the shower gel application switch can be turned on to increase the amount of shower gel used, and / or the essential oil application switch can be turned on to apply essential oil to the user, and / or the water spray nozzle can be turned on to spray water on the user to reduce the friction between the user and the brush head and improve the user experience.

[0031] Measure the pressing displacement of the user pressing the brush head under the same voltage feedback. When the pressing displacement of the brush head is not less than the second preset displacement range (the second preset displacement range is not less than the first preset displacement range and not greater than the preset displacement range corresponding to the same voltage feedback signal (i.e., the second preset displacement range is greater than or equal to the first preset displacement range and less than or equal to the preset displacement range corresponding to the preset rotational resistance range received by the brush head), for example: the second preset displacement range can be the preset displacement range corresponding to the same voltage feedback signal, that is: the preset displacement range corresponding to the preset rotational resistance range received by the brush head)), no processing is performed, and the scrubbing machine remains in its original state and continues to operate.

[0032] In this control method, the second preset displacement range is not less than the first preset displacement range. Among them, when the second preset displacement range is equal to the first preset displacement range, the following control can be achieved: when the rotational resistance information received by the brush head is within the preset rotational resistance range and the pressing displacement of the brush head is less than the first preset displacement range (or the second preset displacement range), turn on the strong cleaning mode of the scrubbing machine; when the rotational resistance information received by the brush head is within the preset rotational resistance range and the pressing displacement of the brush head is not less than the first preset displacement range (or the second preset displacement range), control the scrubbing machine to remain in its original state and operate.

[0033] When the second preset displacement range is greater than the first preset displacement range, the following control can be achieved: when the rotational resistance information received by the brush head is within the preset rotational resistance range and the pressing displacement of the brush head is less than the first preset displacement range, turn on the strong cleaning mode of the scrubbing machine; when the rotational resistance information received by the brush head is within the preset rotational resistance range and the pressing displacement of the brush head is not less than the second preset displacement range, control the scrubbing machine to remain in its original state and operate; when the rotational resistance information received by the brush head is within the preset rotational resistance range and the pressing displacement of the brush head is between the first preset displacement range and the second preset displacement range (i.e., measure the pressing displacement of the user pressing the brush head under the same voltage feedback, the pressing displacement of the brush head is not less than the first preset displacement range and less than the second preset displacement range), at this time, the strong cleaning module can be turned on, or the scrubbing machine can remain in its original state and continue to operate, or the normal cleaning mode can be turned on. In the normal cleaning mode, control the scrubbing machine to perform at least one of the following operations: turn on the shower gel application switch of the scrubbing machine, turn on the essential oil application switch of the scrubbing machine, and turn on the water spray nozzle of the scrubbing machine. Among them, the opening duration of the shower gel application switch, the opening duration of the essential oil application switch, and the opening duration of the water spray nozzle in the normal cleaning mode can be shorter than the opening duration of the shower gel application switch, the opening duration of the essential oil application switch, and the opening duration of the water spray nozzle in the strong cleaning mode respectively, so that the amount of shower gel applied, the amount of essential oil applied, and the amount of water sprayed by the water spray nozzle in the normal cleaning mode are less than the amount of shower gel applied, the amount of essential oil applied, and the amount of water sprayed by the water spray nozzle in the strong cleaning mode respectively.

[0034] In the control method of this back scrubber, the usage amounts of shower gel, essential oil, and water spray can be adjusted according to the user's skin condition, further improving the performance of the back scrubber.

[0035] In some exemplary embodiments, the control method of the back scrubber further includes: Measuring the distance between the user and the back scrubber; Based on the distance between the user and the back scrubber being greater than a preset distance, adjusting the rotation speed of the brush head to the lowest.

[0036] The back scrubber may include a TOF module, and the TOF module can measure the distance between the user and the back scrubber. For example, the TOF module can measure the distance between the user and the brush head of the back scrubber. When the TOF module measures that the user has left the back scrubber by more than a preset distance (such as 50 cm or other distances), the rotation speed of the brush head of the back scrubber can be adjusted to the lowest, avoiding the waste of energy caused by the brush head running at high speed all the time when not in use and saving the energy consumption of the back scrubber.

[0037] When the user's body presses the brush head of the back scrubber again, the rotation speed of the brush head of the back scrubber can be increased again according to the measured rotation resistance information of the brush head (such as the voltage signal of the brush head motor collected by the acquisition circuit) to facilitate scrubbing.

[0038] In some exemplary embodiments, the control method of the back scrubber further includes: Based on receiving a signal indicating the end of the scrubbing program, controlling the brush head to stop rotating to end the scrubbing program and turning on the care mode of the back scrubber.

[0039] Among them, the back scrubber may include at least one of a physiotherapy module (such as a red and blue light physiotherapy module, an ultraviolet physiotherapy module, etc.), an essential oil application switch, and a drying module. In the care mode, control the back scrubber to perform at least one of the following operations: turn on the physiotherapy module of the back scrubber; turn on the essential oil application switch of the back scrubber; and turn on the drying module of the back scrubber.

[0040] After the scrubbing program ends, the back scrubber can automatically turn on the care mode. For example, automatically turn on the red and blue light physiotherapy module, ultraviolet and other physiotherapy modules of the back scrubber, and / or automatically turn on the essential oil application switch of the back scrubber, and / or automatically turn on the drying module of the back scrubber to solve the user's skin problems or dry the user's body. Of course, the user can also turn on the care mode by himself. For example, the user can turn on the red and blue light physiotherapy module, ultraviolet physiotherapy module and other physiotherapy modules by himself, and / or turn on the essential oil application switch of the back scrubber by himself, and / or turn on the drying module of the back scrubber by himself to solve the skin problems of the back or other parts of the body.

[0041] In some exemplary embodiments, the signal indicating the end of the scrubbing program includes that the rotational resistance information of the brush head is within a preset idling resistance range and the duration exceeds a first preset duration. Wherein, the rotational resistance information of the brush head being within the preset idling resistance range indicates that the user's body is not in contact with the brush head and the user is not scrubbing. At this time, the brush head does not receive the rotational frictional resistance from the user's body, and the brush head and the brush head motor are in an idling state.

[0042] When the rotational resistance information of the brush head is within the preset idling resistance range and the duration of this state exceeds the first preset duration, that is, the state where the user is not scrubbing exceeds the first preset duration. At this time, it can be considered that the user has ended the scrubbing, and the rotation of the brush head can be controlled to stop to end the scrubbing program, and the care mode can be automatically or manually activated.

[0043] Of course, the signal indicating the end of the scrubbing program can also be sent by the user. That is, after receiving the signal sent by the user to end the scrubbing, the rotation of the brush head can be controlled to stop to end the scrubbing program, and the care mode can be automatically or manually activated.

[0044] In some exemplary embodiments, the control method of the scrubbing machine further includes: Based on the duration that the scrubbing machine is in an unused state exceeding a second preset duration, control the scrubbing machine to shut down.

[0045] When the duration that the scrubbing machine is in an unused state (such as: the brush head stops rotating or rotates at the lowest speed, the physiotherapy module is not started, the shower gel application switch is not turned on, the drying module is not working, the water spray nozzle does not spray water, etc.) exceeds the second preset duration (such as: 3 minutes or other durations), control the scrubbing machine to shut down to save energy. Specifically, when the user leaves the scrubbing machine but does not exceed a preset distance (such as: 50 cm or other distances), but does not use the scrubbing machine for more than the second preset duration (such as: 3 minutes or other durations), the scrubbing machine can be temporarily shut down to save energy.

[0046] The second preset duration and the first preset duration can be set to be equal or unequal.

[0047] The embodiment of the present application provides a control device for a scrubbing machine, including a processor, a memory, and a computer program stored on the memory and executable on the processor. When the computer program is executed by the processor, the steps of the control method of the scrubbing machine in any of the above embodiments are implemented.

[0048] The embodiment of the present application provides a control system for a scrubbing machine, such as Figure 2As shown, it includes the control device of the back scrubber in any of the above embodiments and a resistance information acquisition module. The resistance information acquisition module is configured to measure the rotational resistance information received by the brush head of the back scrubber and is electrically connected to the control device. The control device is configured to control the driving circuit of the brush head motor that drives the brush head to rotate according to the signal acquired by the resistance information acquisition module. Among them, the control device may include a main control board, and the resistance information acquisition module may include an acquisition circuit. The acquisition circuit can acquire the current signal of the brush head motor and convert the current signal into a voltage signal. Of course, the resistance information acquisition module can also use other methods outside the acquisition circuit to obtain the rotational resistance information received by the brush head.

[0049] When the user's body touches the brush head of the back scrubber, the brush head receives a rotational resistance, the output torque of the brush head motor increases, the current generated by the brush head motor increases, and the acquisition circuit can acquire this current signal and convert the increased current signal into a voltage signal. The control device of the back scrubber can adjust the PWM waveform of the driving circuit of the brush head motor according to the received voltage signal to increase the output power of the driving circuit and the brush head motor, so that the rotation speed of the brush head can remain unchanged or increase, providing a better back scrubbing experience for the user.

[0050] In some exemplary embodiments, as Figure 2 shown, the control system of the back scrubber further includes a displacement measurement module. The displacement measurement module is configured to measure the pressing displacement received by the brush head and is electrically connected to the control device. The control device is configured to control the state of at least one of the shower gel application switch, essential oil application switch, and water spray nozzle of the back scrubber according to the signals acquired by the resistance information acquisition module and the displacement measurement module. Among them, the displacement measurement module may include a TOF module.

[0051] The TOF module is used to measure the pressing displacement of the user pressing the brush head. When the rotational resistance information received by the brush head is within a preset rotational resistance range, but the pressing displacement of the brush head is less than the first preset displacement range (less than the preset displacement range corresponding to this preset rotational resistance range), the strong cleaning mode can be activated (for example: activate the shower gel application switch to increase the amount of shower gel used); when the rotational resistance information received by the brush head is within the preset rotational resistance range, and the pressing displacement of the brush head is not less than the preset displacement range corresponding to this preset rotational resistance range, control the back scrubber to operate in its original state; when the rotational resistance information received by the brush head is within the preset rotational resistance range, and the pressing displacement of the brush head is not less than the first preset displacement range and less than the preset displacement range corresponding to this preset rotational resistance range, the strong cleaning mode can be activated, or the back scrubber can be made to continue operating in its original state, or the normal cleaning mode can be activated.

[0052] In some exemplary embodiments, as Figure 2As shown, the control system of the back scrubber further includes a displacement measurement module, which is configured to measure the distance between the user and the back scrubber and is electrically connected to the control device. The control device is configured to control the operation of the drive circuit according to the signal collected by the displacement measurement module. The displacement measurement module may include a TOF module.

[0053] When the TOF module measures that the user has left the back scrubber by more than a preset distance (i.e., the distance between the user and the back scrubber is greater than the preset distance), the rotation speed of the brush head of the back scrubber can be adjusted to the lowest, avoiding the waste of energy caused by the high-speed operation of the brush head when not in use.

[0054] The displacement measurement module for measuring the distance between the user and the back scrubber can also indirectly obtain the pressing displacement of the brush head by measuring the distance between the user and the back scrubber when the user's body is in contact with the brush head.

[0055] It should be understood that the displacement measurement module for measuring the pressing displacement of the brush head and the displacement measurement module for measuring the distance between the user and the back scrubber can be the same displacement measurement module or different displacement measurement modules.

[0056] The embodiment of the present application provides a non-transitory computer-readable storage medium, on which a computer program that can run on a processor is stored. When the computer program is executed by the processor, the steps of the control method of the back scrubber in any of the above embodiments are implemented.

[0057] The embodiment of the present application provides a back scrubber, as Figure 2 shown, including the control system of the back scrubber in any of the above embodiments.

[0058] In some exemplary embodiments, as Figure 2 shown, the back scrubber may further include a brush head, a brush head motor for driving the rotation of the brush head, a drive circuit for driving the brush head motor, a shower gel application switch, a drying module, an essential oil application switch, a water spray nozzle, a physiotherapy module, etc. The brush head motor, the drive circuit, the shower gel application switch, the drying module, the essential oil application switch, the water spray nozzle, and the physiotherapy module can be electrically connected to the control device so that the control device can control the operation of the brush head motor, the drive circuit, the shower gel application switch, the drying module, the essential oil application switch, the water spray nozzle, and the physiotherapy module.

[0059] Next, in combination with Figure 2 and Figure 3 , the back scrubber and its control process in an embodiment of the present application will be specifically described.

[0060] As Figure 2As shown in the figure, the back scrubber mainly includes a brush head, a brush head motor and its drive circuit and acquisition circuit, a control device (main control board), a shower gel application switch, a red and blue light physiotherapy module, a displacement measurement module (TOF module), etc. When the user uses the back scrubber, they will come into contact with the brush head. When the brush head touches the human skin, it will generate resistance, causing a change in the current of the brush head motor. According to the corresponding current change, the main control board of the back scrubber performs corresponding operations.

[0061] As Figure 3 shown, the corresponding operation process of the back scrubber is as follows; 1. The user presses the power-on button of the back scrubber, and the back scrubber starts, and the function of the TOF module starts.

[0062] 2. When the user does not adjust the gear of the back scrubber, the brush head of the back scrubber runs at the lowest gear (lowest speed).

[0063] 3. When the user's body touches the brush head of the back scrubber, the rotation of the brush head is blocked, the torque of the brush head motor increases, and the generated current increases. The increased current signal is converted into a voltage signal through the acquisition circuit.

[0064] 4. The main control board of the back scrubber adjusts the PWM waveform of the drive circuit of the brush head motor according to the received voltage signal, improves the output power of the drive circuit, and provides a better back scrubbing experience for the user.

[0065] 5. At the same time, measure the pressing displacement of the user pressing the brush head through the ranging function of the TOF module, and make a preset value for the generated voltage feedback signal under the same pressing displacement in advance, that is, correspond the preset voltage feedback signal range with the preset displacement range of the brush head in advance.

[0066] 6. Measure the displacement of the user pressing the brush head under the same voltage feedback signal. When the pressing displacement of the brush head is less than 20% of the preset pressing displacement value (the first preset displacement range, that is, when the actual voltage feedback signal is within the preset voltage feedback signal range, the actual pressing displacement of the brush head is less than 20% of the preset displacement range corresponding to this preset voltage feedback signal range), it indicates that the user can obtain a relatively large frictional resistance with a relatively small pressing displacement of the brush head. It is judged that the user's skin is rough or the health status is not good. At this time, the shower gel application switch can be turned on to increase the amount of shower gel used and improve the user experience.

[0067] 7. When measuring the displacement of the user pressing the brush head under the same voltage feedback signal, when the pressing displacement of the brush head is not less than the preset pressing displacement value (the second preset displacement range), no processing is performed on the back scrubber.

[0068] 8. When the TOF module determines that the user has left the back scrubber by 50 cm (preset distance), the rotation speed of the brush head of the back scrubber is adjusted to the lowest to save energy.

[0069] 9. When the user presses the brush head of the back scrubber again, the rotation speed of the back scrubber is increased again according to the measured voltage signal.

[0070] 10. After the back scrubbing program ends, the red and blue light physiotherapy module is turned on to solve the user's skin problems. Alternatively, the user can also turn on the red and blue light physiotherapy by themselves to solve the skin problems of the back or other parts of the body.

[0071] 11. When the user leaves the back scrubber by no more than 50 cm but does not use the back scrubber for more than 3 minutes, the back scrubber is controlled to shut down temporarily to save energy.

[0072] In summary, the control method of the back scrubber in the embodiments of the present application can improve the user experience when the user takes a bath, and solves the problem that the existing back scrubber can only be manually shifted; moreover, the back scrubber can also automatically adjust the rotation speed of the brush head motor according to the pressing resistance of the brush head received by the user, increasing the torque during back scrubbing; in addition, in cooperation with the TOF module, it can more precisely judge the user's skin condition and perform body wash lubrication and red and blue light physiotherapy.
