[0050] See also Figures 1 to 3 An electric cleaning brush 100 provided in one embodiment of the present application includes a housing 10, a motor 20, and a brush head 30. The motor 20 is disposed within the housing 10, and its output shaft is in driving connection with the brush head 30 to drive the brush head 30 to perform cleaning actions, such as rotation and reciprocating movement. The motor 20 may be, but is not limited to, a brushed DC motor 20 and may include a reduction gear mechanism.

[0051] In one embodiment, the electric cleaning brush 100 is used for household cleaning. In other embodiments, the electric cleaning brush 100 can also be used for personal care cleaning, such as teeth cleaning, etc., which is not specifically limited here.

[0052] In some embodiments, the motor 20 has at least two operating gears, and in different operating gears, the motor 20 operates with different operating parameters, including voltage, current, reduction ratio, operating frequency, operating time, etc.

[0053] In this way, the motor 20 can adjust its own working state by switching working gears to adapt to different working requirements.

[0054] In some embodiments, the electric cleaning brush 100 may further include a controller 40 and a switch button 50 . The controller 40 is used to control the operating parameters of the motor 20 , i.e., gear switching. The switch button 50 can control the start and stop of the motor 20 .

[0055] In addition, the electric cleaning brush 100 may further include a battery 60 and an indicator light 70. The battery 60 is disposed in the housing 10 and is electrically connected to the main board and / or the motor 20. The indicator light 70 can emit light signals to the outside to display the working status of the electric cleaning brush 100, for example, when the electric cleaning brush 100 is started or stopped.

[0056] The housing 10 includes a handle portion 11 and a head portion 13. The handle portion 11 of the housing 10 is used for the user to hold when using the electric cleaning brush 100. The motor 20 can be installed in the head portion 13. The battery 60 and the controller 40 can be arranged in the handle portion 11. The switch button 50 can also be arranged in the handle portion 11.

[0057] In some embodiments, the electric cleaning brush 100 includes at least two brush heads 30 of different specifications, and all of the brush heads 30 are selectively connected to the motor 20 in a detachable transmission manner.

[0058] It is understandable that different specifications of brush heads 30 may refer to different sizes, shapes, materials, etc. This solution is mainly used in electric cleaning brushes 100 products, especially in products with replaceable cleaning brush heads. First, it is required that more than two brush heads 30 can be replaced.

[0059] In this way, the user can install the corresponding brush head 30 according to different usage scenarios, different levels of dirt, etc., which helps to improve the applicability of the electric cleaning brush 100.

[0060] Please also refer to Figure 4 The control method of the electric cleaning brush provided in one embodiment of the present application can be used to control the above-mentioned electric cleaning brush. The control method includes:

[0061] S200: Obtain the current of the motor in the electric cleaning brush and obtain a comparison current.

[0062] As can be understood, the rotor generates back EMF during rotation, so the motor's operating current is correlated with its speed. The current motor current can be obtained via the controller's ADC (analog-to-digital converter). The comparison current can be a previously acquired historical value of the motor's operating current or a preset constant. The preset constant can be obtained from a pre-stored data table that records the motor's standard current under different operating conditions.

[0063] S400: Compare the current current with the comparison current to obtain a comparison result.

[0064] The comparison result between the current current and the comparison current can represent the actual speed of the motor. For example, if the current current is significantly greater than the comparison current, it means that the back electromotive force generated by the rotor is small, and the speed of the motor is reduced or lower than expected; conversely, if the current current is significantly less than the comparison current, it means that the back electromotive force generated by the rotor is large, and the speed of the motor is increased or higher than expected.

[0065] S600: Adjust the operating parameters of the motor according to the comparison result.

[0066] After determining the change in motor speed based on the current, the motor's operating parameters, including voltage, current, reduction ratio, operating frequency, and operating duration, can be adjusted accordingly to ensure the motor's speed. For example, if the comparison results indicate a decrease in motor speed, the motor's speed can be increased by at least one of increasing the operating voltage, optimizing the reduction ratio, or optimizing the power supply frequency.

[0067] The control method for the electric cleaning brush can obtain the motor's operating current and compare it to determine the actual motor speed. It can then adjust the motor's operating parameters to stabilize the motor's speed. This allows the control method to promptly adjust the motor to ensure effective cleaning if the cleaning conditions of the electric cleaning brush change, such as changes in the target surface or the level of dirt, which causes changes in brush head resistance and, consequently, motor speed.

[0068] Please also refer to Figure 5In some embodiments, the step of adjusting the operating parameters of the motor according to the comparison result, i.e., step S600, specifically includes:

[0069] S610: Control the operating voltage of the motor according to the comparison result.

[0070] It can be understood that as the operating voltage changes, the power of the motor changes accordingly. Increasing the operating voltage helps to increase the speed of the motor, while reducing the operating voltage helps to reduce the speed of the motor.

[0071] In this way, the motor can change its own speed most directly and conveniently according to the adjustment of the working voltage to maintain the cleaning effect.

[0072] Please also refer to Figure 6 In some embodiments, the step of controlling the operating voltage of the motor according to the comparison result, i.e., step S610, specifically includes:

[0073] S611 . If the comparison result is that the ratio of the current current to the comparison current is k≥a, then the operating voltage is increased; wherein a>1.

[0074] It can be understood that when the ratio k is greater than 1, it means that the current current is greater than the comparison current, the back electromotive force generated by the rotor is smaller, and the speed of the motor is reduced or lower than expected.

[0075] In this way, when the speed of the motor decreases or is lower than expected, it can be adjusted in time by increasing the working voltage to increase the speed of the motor and maintain the cleaning effect.

[0076] Please also refer to Figure 7 In some embodiments, if the comparison result is that the ratio of the current current to the comparison current is k≥a, the step of increasing the operating voltage, i.e., step S611, specifically includes:

[0077] S6111. If a≤k<b, then the control operating voltage is increased by an increment of X; if b≤k, then the control operating voltage is increased by an increment of Y; wherein X<Y.

[0078] It can be understood that a < b. If a ≤ k < b, it means that the current has increased or is within a relatively lower range than expected, and accordingly, the motor speed needs to be increased by a smaller amount. If b ≤ k, it means that the current has increased or is within a relatively higher range than expected, and accordingly, the motor speed needs to be increased by a larger amount.

[0079] Correspondingly, an increment of the working voltage of X may correspond to increasing the working gear of the motor by one gear, and an increment of the working voltage of Y may correspond to increasing the working gear of the motor by two gears.

[0080] In this way, the electric cleaning brush can make targeted adjustments to the motor according to the difference between the current current and the comparison current to maintain a stable rotation speed.

[0081] In some embodiments, the working gears of the electric cleaning brush include the first gear, the second gear, and the third gear. Before the steps of obtaining the current current of the motor in the electric cleaning brush and obtaining the comparison current, that is, before step S200, the following steps are further included:

[0082] Start the electric cleaning brush and control the motor of the electric cleaning brush to run at the first gear.

[0083] In some embodiments, if the comparison result is that the ratio of the current current to the comparison current is k≥a, the step of increasing the working voltage, that is, step S611 specifically includes: if 1.3≤k<1.7, then the motor is controlled to switch to the second gear; if 1.7≤k, then the motor is controlled to switch to the third gear.

[0084] When the motor is running in the first gear, the operating voltage is U1; when the motor is running in the second gear, the operating voltage is U2; when the motor is running in the third gear, the operating voltage is U3; U1 < U2 < U3. Specifically, U1 can be, but not limited to, 3V, U2 can be, but not limited to, 4V, and U3 can be, but not limited to, 5V.

[0085] If the front current increases by at least 30% and less than 70% compared to the comparison current, it indicates that the electric cleaning brush is being used in a moderately dirty environment and the increase in resistance to the brush head is moderate. The motor can be switched to second gear and its speed can be significantly restored. If the front current increases by at least 70% compared to the comparison current, it indicates that the electric cleaning brush is being used in a significantly dirty environment and the increase in resistance to the brush head is significant. The motor can be switched to third gear to overcome the resistance and restore the speed.

[0086] In some embodiments, the step of controlling the operating voltage of the motor according to the comparison result, i.e., step S610, specifically includes:

[0087] If the comparison result is that the ratio of the current current to the comparison current is k≤e, the operating voltage is reduced; wherein e<1.

[0088] It can be understood that when the ratio k is less than 1, it means that the current current is smaller than the comparison current, the back electromotive force generated by the rotor is larger, and the speed of the motor increases or is higher than expected.

[0089] In this way, when the speed of the motor increases or is higher than expected, it can be adjusted in time by reducing the operating voltage to reduce the speed of the motor so that it can work at a reasonable speed and reduce splashing caused by cleaning.

[0090] In some embodiments, if the comparison result is that the ratio of the current current to the comparison current is k≤e, the step of reducing the operating voltage specifically includes:

[0091] If f<k≤e, then the reduction amount of the control working voltage is increased by Z; if k≤f, then the reduction amount of the control working voltage is increased by W; wherein, Z<W.

[0092] It can be understood that f < e. If f < k ≤ e, it means that the current has decreased or is within a relatively lower range than expected, and accordingly, the motor speed needs to be reduced by a smaller amount. If k ≤ f, it means that the current has decreased or is within a relatively higher range than expected, and accordingly, the motor speed needs to be reduced by a larger amount.

[0093] Correspondingly, a reduction in the operating voltage of Z may correspond to lowering the operating gear of the motor by one gear, and a reduction in the operating voltage of W may correspond to lowering the operating gear of the motor by two gears.

[0094] In this way, the electric cleaning brush can make targeted adjustments to the motor according to the difference between the current current and the comparison current to maintain a stable rotation speed.

[0095] In some embodiments, the working gears of the electric cleaning brush include the first gear, the second gear, and the third gear. Before the steps of obtaining the current current of the motor in the electric cleaning brush and obtaining the comparison current, that is, before step S200, the following steps are further included:

[0096] Start the electric cleaning brush and control the motor of the electric cleaning brush to run at the third gear.

[0097] In some embodiments, if the comparison result is that the ratio of the current current to the comparison current is k≤e, the step of reducing the operating voltage specifically includes: if 0.3≤k<0.7, controlling the motor to switch to the second gear; if 0.3≤k, controlling the motor to switch to the first gear.

[0098] When the motor is running in the first gear, the operating voltage is U1; when the motor is running in the second gear, the operating voltage is U2; when the motor is running in the third gear, the operating voltage is U3; U1 < U2 < U3. Specifically, U1 can be, but not limited to, 3V, U2 can be, but not limited to, 4V, and U3 can be, but not limited to, 5V.

[0099] If the front current drops by at least 30% and less than 70% compared to the comparison current, it indicates that the electric cleaning brush is used in a moderately reduced level of dirt and the resistance to the brush head has been moderately reduced. The motor can be switched to the second gear and its speed can be significantly restored. If the front current drops by at least 70% compared to the comparison current, it indicates that the electric cleaning brush is used in a significantly reduced level of dirt and the resistance to the brush head has been significantly reduced. The motor can be switched to the first gear and its speed can be restored.

[0100] Please also refer to Figure 8 In some embodiments, the step of obtaining the current of the motor in the electric cleaning brush and obtaining the comparison current, that is, step S200, specifically includes:

[0101] S210 , detecting the working current of the motor at a set sampling rate, and taking the current detection result as the current current and the previous detection result as the comparison current.

[0102] In other words, the motor's operating current is detected once every set time interval. If the current current is the result of the nth detection, the result of the n-1th detection is used as the comparison current. Here, n is an integer, and n≥2.

[0103] By continuously monitoring the motor's operating current and comparing it with the previous current, changes in the motor's operating current can be determined, and thus changes in motor speed can be determined. For example, if the current current is greater than the comparison current, the motor speed is reduced and the motor's operating resistance is increased; if the current current is less than the comparison current, the motor speed is increased and the motor's operating resistance is reduced.

[0104] In this way, the operating parameters of the motor are adjusted based on the historical value of the motor operating current obtained last time, which can adapt to the working changes of the motor in real time and maintain the stability of the cleaning effect of the electric cleaning brush.

[0105] In some embodiments, the sampling rate is set to be no greater than 1 time / min. In other words, the interval between two detections of the working current is no less than 1 minute.

[0106] In this way, the motor has enough time to rebalance, which can reduce the possibility of continuous triggering of operating parameter adjustments.

[0107] Please also refer to Figure 9 In some embodiments, after the step of adjusting the operating parameters of the motor according to the comparison result, that is, after step S600, the following steps are further included:

[0108] S800: Obtain the temperature of the motor.

[0109] The motor may have a temperature sensor or a temperature limiter to provide temperature feedback. It is understood that obtaining the temperature of the motor may be either obtaining a temperature value or directly obtaining a comparison result between the temperature and a first set value, that is, whether the temperature is not less than the first set value.

[0110] S1000: If the temperature of the motor is not less than a first set value, cut off the power supply of the motor.

[0111] Understandably, when the motor temperature is no less than a first set value, it indicates that the motor is operating at high load and is at risk of failure. The motor has a temperature limiter that cuts off power and prevents the motor from starting if the motor temperature is no less than the first set value. When the motor temperature drops to no more than a second set value, the temperature limiter resets, allowing the motor to be restarted.

[0112] In this way, the motor can reduce the possibility of being burned out due to excessive current, which helps to increase the service life of the electric cleaning brush.

[0113] In order to facilitate understanding of the control method of the electric cleaning brush of the present application, a specific application example is provided below for illustration. In the specific application example, the control method of the electric cleaning brush of the present application includes the following steps:

[0114] Step 1. According to different user scenarios, the user selects a matching brush head from the accessories and installs the brush head on the whole machine;

[0115] Step 2: Press the switch button to start the electric cleaning brush;

[0116] Step 3, running stage: the battery provides voltage to the controller, the indicator light on the controller lights up, indicating that it has started, and the first gear is used for startup. The power supply voltage in the first gear is 3V;

[0117] Step 4, adjustment stage: During actual cleaning, the brush head has different resistance to motor rotation due to different degrees of dirt. When the resistance increases, the motor speed decreases, and the current increases when the voltage remains unchanged. The following operations are performed: 1. The current is evaluated through the ADC components of the controller. When the current increases by 30%, the controller determines that the resistance is increased and automatically increases to the second gear. The second gear uses a 4V voltage for power supply to increase the power of the whole machine, thereby increasing the motor speed; 2. The current is evaluated through the ADC components of the controller. When the current increases by 70%, the controller determines that the resistance is large and automatically increases to the third gear. The third gear uses a 5V voltage for power supply to increase the motor power, thereby increasing the speed.

[0118] In this way, in different scenarios, the working current of the motor can be obtained and compared with the historical value of the motor working current obtained last time. If the working current increases, it means that the motor speed decreases and the resistance encountered by the electric cleaning brush increases. It is necessary to increase the working voltage and speed to achieve automatic adjustment of the working gear to meet the cleaning effect.

[0119] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.

[0120] Based on the same inventive concept, the present application also provides an electric cleaning brush for implementing the aforementioned control method. The solution provided by this device is similar to the solution described in the aforementioned method. Therefore, the specific limitations of one or more electric cleaning brush embodiments provided below can be found in the aforementioned limitations of the control method and will not be further elaborated here.

[0121] In some embodiments, the electric cleaning brush includes a current module, a comparison module, and a control module, wherein:
