[0059] The principle of electric toothbrush cleaning mainly relies on its vibration or rotation action to remove dental plaque and food residues on the tooth surface. Among them, electric toothbrushes using sonic technology do not rely on mechanical rotation, but utilize high-speed vibration. The hydrodynamic effects generated by these vibrations can create tiny bubbles in the oral cavity to help remove dental plaque on the tooth surface and in hard-to-reach areas. And the high-speed vibration of the electric toothbrush needs to be generated by one or more components (such as electromagnetic drivers or piezoelectric ceramic materials) driven by the electric toothbrush motor. Therefore, the quality of the electric toothbrush motor affects the use effect of the electric toothbrush using sonic technology.

[0060] Therefore, referring to Figure 1 , the present invention provides a method for detecting an electric toothbrush motor, which is applied to an electric toothbrush motor detection device. The electric toothbrush motor detection device includes a power supply module for providing a corresponding preset voltage to the electric toothbrush motor. The detection method includes:

[0061] Step S100: Obtain a plurality of corresponding first working parameters when the electric toothbrush motor is powered by a first preset voltage;

[0062] Step S200: Obtain a plurality of corresponding second working parameters when the electric toothbrush motor is powered by a second preset voltage;

[0063] Step S300: Determine whether the working performance of the electric toothbrush motor meets a preset standard based on the matching results of the plurality of first working parameters, the plurality of second working parameters and a preset working parameter range;

[0064] Wherein, the working parameters include working current, working noise, and working amplitude.

[0065] It should be understood that the motor is usually driven by a control circuit through a PWM signal. Because it allows precise control of the motor speed and operating mode, while also improving energy efficiency. The control module generates a PWM signal with a specific duty cycle according to the user's selection or a preset program. Among them, the duty cycle determines the proportion of time the signal is at a high level within a cycle, thereby affecting the average voltage level applied to the motor, and further controlling the motor speed. The drive circuit in the power supply module receives the PWM signal from the control module and amplifies it to a level sufficient to drive the motor to work. Since the PWM signal effectively changes the average voltage across the motor, the motor can operate at different speeds. In addition, by quickly switching the power supply, PWM can also reduce energy loss and improve efficiency. Therefore, it can be understood that the control module can regulate the preset voltage output from the power supply module to the electric toothbrush motor by changing the duty cycle of the output PWM signal. Among them, the rotation speed of the electric toothbrush motor is different under different preset voltages. In practical applications, the battery in the electric toothbrush will experience a decrease in power due to continuous operation, and the decrease in battery power will lead to a decrease in the output voltage. At this time, if the control device in the electric toothbrush still outputs a PWM signal with the same duty cycle, the voltage input to the electric toothbrush motor will become smaller. Therefore, the control module controls the power supply module to output multiple different preset voltages to effectively simulate the actual working process of the electric toothbrush motor in the electric toothbrush, and then obtain the working parameters that conform to the actual application.

[0066] In this embodiment, the control module outputs a corresponding PWM signal with a first preset duty cycle to the drive circuit in the power supply module, so that the power supply module outputs a corresponding first preset voltage and supplies power to the electric toothbrush motor, thereby driving the electric toothbrush motor to work. Among them, when the electric toothbrush motor is powered by the first preset voltage, the electric toothbrush motor detection device will obtain multiple corresponding first working parameters of the electric toothbrush motor and record them. Further, the control module outputs a corresponding PWM signal with a second preset duty cycle to the drive circuit in the power supply module, so that the power supply module outputs a corresponding second preset voltage and supplies power to the electric toothbrush motor, thereby driving the electric toothbrush motor to work. Among them, when the electric toothbrush motor is powered by the second preset voltage, the electric toothbrush motor detection device will obtain multiple corresponding second working parameters of the electric toothbrush motor and record them. The control module determines whether multiple corresponding first working parameters and multiple corresponding second working parameters fall within the range of the voltage and working parameter mapping table by means of the voltage and working parameter mapping table set therein. It can be understood that the voltage and working parameter mapping table is the corresponding parameter generated by R & D personnel based on multiple qualified electric toothbrush motors.

[0067] In this embodiment, the working parameters of the electric toothbrush motor detected by the electric toothbrush motor detection device include working current, working noise, and working amplitude. It can be understood that even under the condition of a fixed supply voltage, the current magnitude of the motor will change due to differences in motor performance. The performance of the motor is determined by multiple factors, and these factors can directly or indirectly affect the working current. The load of the motor directly affects its working current. When the motor bears a heavier load, it needs to generate greater torque to maintain the same rotational speed, which usually leads to an increase in current. The efficiencies of different motors vary. High-efficiency motors lose less energy during the conversion of electrical energy into mechanical energy. Therefore, at the same output power, the working current of a high-efficiency motor may be smaller. Internal friction (such as bearing friction) and other forms of resistance (such as air resistance, friction between the brush and the commutator, etc.) will affect the current required for the motor to operate. Lower friction and resistance mean that the motor can achieve the same effect with a smaller current. Even for motors of the same model, due to tolerances in the manufacturing process, their actual performance may vary slightly. In addition, over time, the aging of the internal components of the motor may also cause changes in its performance, including changes in current consumption. Finally, different design parameters, such as winding type, material selection, etc., will also affect the current consumption of the motor at a given voltage. The working noise generated by the motor during operation can be mainly divided into three types: mechanical vibration, electromagnetic vibration, and aerodynamic noise. Mechanical vibration noise includes bearing friction and wear, rotor imbalance, assembly problems, etc.; electromagnetic vibration noise includes magnetic field pulsation, current harmonics, magnetostrictive effect, etc.; aerodynamic noise includes resonance of the motor housing. Therefore, during the actual detection process, it is necessary to ensure that the external conditions are consistent to avoid affecting the accuracy of the detected working parameters.

[0068] By controlling the power supply module in the electric toothbrush motor detection device to output a corresponding preset voltage, when the electric toothbrush motor is powered by the first preset voltage, a plurality of corresponding first working parameters are obtained; when the electric toothbrush motor is powered by the second preset voltage, a plurality of corresponding second working parameters are obtained; wherein, the first working parameters and the second working parameters include working current, working noise, and working amplitude. By obtaining the electric toothbrush motor under the condition of being powered by different preset voltages, a plurality of different and corresponding working parameters are further obtained. Further, by comparing the plurality of different and corresponding working parameters with the corresponding working parameter ranges, the corresponding matching results are obtained. If all the plurality of different and corresponding working parameters are within the corresponding working parameter ranges, it can be confirmed that the working performance of the electric toothbrush motor meets the preset standard. By this method, the quality of the electric toothbrush motors produced by the manufacturer can be effectively improved, and misjudgment can be effectively avoided.

[0069] Reference Figure 2, in an embodiment of the present invention, the electric toothbrush motor detection device includes a voltage detection module and a voltage regulation module; the input end of the voltage detection module is electrically connected to the output end of the power supply module; the input end of the voltage regulation module is electrically connected to the output end of the power supply module, and the output end of the voltage regulation module is electrically connected to the power supply end of the electric toothbrush motor; before the step of when the electric toothbrush motor is powered by a first preset voltage, the method includes:

[0070] Step S400: When the power supply module outputs a supply voltage according to a first preset voltage, obtain a first voltage value at the input end of the voltage regulation module;

[0071] Step S500: When the first voltage value does not correspond to the first preset voltage, control the voltage regulation module to convert the first voltage value into the first preset voltage and output it.

[0072] In this embodiment, the voltage detection module can be implemented by a voltage division detection circuit, a voltage comparison circuit, etc.; the voltage regulation module can be implemented by a linear voltage regulator circuit, a switching voltage regulator circuit, etc. By electrically connecting the input end of the voltage detection module to the output end of the power supply module, the output voltage of the power supply module can be effectively confirmed, so as to judge whether the voltage output by the power supply module meets the preset voltage. When the power supply module outputs a supply voltage according to a first preset voltage, the voltage detection module will obtain a first voltage value at the input end of the voltage regulation module, and then output a corresponding voltage detection signal to the control module. The control module confirms whether the voltage output by the power supply module corresponds to the first preset voltage by matching the corresponding voltage detection signal with the first preset voltage. Under the condition that it is confirmed that the corresponding voltage detection signal does not correspond to the first preset voltage, the control module will control the voltage regulation module to convert the first voltage value output by the power supply module to output the first preset voltage to the electric toothbrush motor to be tested, so as to effectively ensure that the supply voltage of the motor is the preset voltage and improve the accuracy of detection.

[0073] Reference Figure 3 , in an embodiment of the present invention, the electric toothbrush motor detection device includes a current detection module, and the current detection module is electrically connected to the power supply end of the electric toothbrush motor; when the electric toothbrush motor is powered by a first preset voltage, obtaining a plurality of corresponding first working parameters includes:

[0074] Step S110: When the electric toothbrush motor is powered by a first preset voltage, obtain a plurality of first working currents at the power supply end of the electric toothbrush motor;

[0075] When the electric toothbrush motor is powered by a second preset voltage, obtaining a plurality of corresponding second working parameters includes:

[0076] Step S210: When the electric toothbrush motor is powered by a second preset voltage, obtain a plurality of second working currents at the power supply end of the electric toothbrush motor.

[0077] In this embodiment, the current detection module can be implemented by circuits such as a shunt resistor detection circuit and a Hall sensing circuit. By electrically connecting the input end of the current detection module to the power supply end of the electric toothbrush motor, the working current of the electric toothbrush motor is detected, and a corresponding current detection signal is output to the control module. Among them, the supply voltage of the electric toothbrush motor will vary because the control module controls the power supply module to output different preset voltages. Therefore, under the condition of different supply voltages of the electric toothbrush motor, the current detection signals detected by the current detection module will also be different. By obtaining different current detection signals under the condition of different supply voltages of the electric toothbrush motor.

[0078] Furthermore, determining whether the working performance of the electric toothbrush motor meets the preset standard based on the matching results of the plurality of first working parameters, the plurality of second working parameters and the preset working parameter range includes:

[0079] Step S310: Based on the matching results of the plurality of first working currents, the plurality of second working currents and the preset working current range, determine whether the working current of the electric toothbrush motor meets the preset standard.

[0080] In this embodiment, the control module controls the power supply module to output the first preset voltage and the second preset voltage respectively in different time periods to supply power to the electric toothbrush motor, and obtains a plurality of first working currents and a plurality of second working currents through the current detection module. The control module combines the obtained plurality of first working currents and plurality of second working currents, and further through the voltage and working current mapping relationship table, thereby determines whether the plurality of corresponding first working currents and plurality of corresponding second working currents fall within the range of the voltage and working current mapping relationship table, and further determines whether the working performance of the electric toothbrush motor meets the standard.

[0081] Reference Figure 4 , in an embodiment of the present invention, the electric toothbrush motor detection device includes a sealed detection chamber and a sound pickup module, and the sound pickup module is arranged in the sealed detection chamber; when the electric toothbrush motor is powered by a first preset voltage, obtaining a plurality of corresponding first working parameters includes:

[0082] Step S120: When the electric toothbrush motor is powered by a first preset voltage, obtain a plurality of first operating noises generated by the operation of the electric toothbrush motor;

[0083] The obtaining of a plurality of corresponding second operating parameters when the electric toothbrush motor is powered by a second preset voltage includes:

[0084] Step S220: When the electric toothbrush motor is powered by a second preset voltage, obtain a plurality of second operating noises generated by the operation of the electric toothbrush motor.

[0085] In this embodiment, to accurately detect the noise generated when the electric toothbrush motor operates, it is necessary to ensure that the electric toothbrush is in a sound-insulated environment to avoid interference from external noises. Therefore, the electric toothbrush motor detection device includes a sealed detection chamber. When performing noise detection on the electric toothbrush motor, the electric toothbrush motor is arranged in the sealed detection chamber, so that the sound pickup module can accurately detect the noise generated when the electric toothbrush motor operates. Among them, the sound pickup module can be implemented by a corresponding type of microphone, so as to detect the noise generated when the electric toothbrush motor operates and output a corresponding noise detection signal to the control module. It can be understood that the rotation speed of the electric toothbrush motor is different under different supply voltage conditions. Therefore, the magnitude of the noise generated by the electric toothbrush motor is also different under different supply voltage conditions. The control module controls the power supply module to output different preset voltages, thereby controlling the electric toothbrush motor to operate at different rotation speeds, and further generating different operating noises.

[0086] Furthermore, the determining whether the operating performance of the electric toothbrush motor meets the preset standard based on the matching results of the plurality of first operating parameters, the plurality of second operating parameters and the preset operating parameter range includes:

[0087] Step S320: Based on the matching results of the plurality of first operating noises, the plurality of second operating noises and the preset operating noise range, determine whether the operating noise of the electric toothbrush motor meets the preset standard.

[0088] In this embodiment, the control module determines whether the operating performance of the electric toothbrush motor meets the standard by judging whether a plurality of corresponding first operating noises and a plurality of corresponding second operating noises fall within the range of the voltage and operating noise mapping relationship table.

[0089] Reference Figure 5, in an embodiment of the present invention, the electric toothbrush motor detection device includes a liquid storage chamber for containing liquid and a housing. The liquid storage chamber is isolated and disposed inside the sealed detection chamber and is fixedly arranged with the housing through the inside of the sealed detection chamber. The sealed detection chamber is also used to collect the liquid splashed out of the liquid storage chamber. When the electric toothbrush motor is powered by a first preset voltage, obtaining a plurality of corresponding first working parameters includes:

[0090] Step S130: When the electric toothbrush motor is fixedly connected to the toothbrush head and the electric toothbrush motor is powered by a first preset voltage, control the toothbrush head to immerse into the liquid surface to a preset depth, so that the sealed detection chamber obtains a plurality of first liquid amounts splashed during the operation of the electric toothbrush motor.

[0091] When the electric toothbrush motor is powered by a second preset voltage, obtaining a plurality of corresponding second working parameters includes:

[0092] Step S230: When the electric toothbrush motor is fixedly connected to the toothbrush head and the electric toothbrush motor is powered by a second preset voltage, control the toothbrush head to immerse into the liquid surface to a preset depth, so that the sealed detection chamber obtains a plurality of second liquid amounts splashed during the operation of the electric toothbrush motor.

[0093] In this embodiment, to detect the working amplitude of the electric toothbrush motor, the electric toothbrush motor is connected to the toothbrush head, so that the toothbrush head is driven to work when the electric toothbrush motor is operating. It can be understood that an electric toothbrush using sonic technology does not rely on mechanical rotation but uses high-speed vibration. The hydrodynamic effects generated by these vibrations can create tiny bubbles in the oral cavity to help remove dental plaque on the tooth surface and in hard-to-reach areas. Therefore, to simulate the actual working environment of the electric toothbrush motor, the electric motor toothbrush is connected to the toothbrush head, and the toothbrush head is immersed into the liquid surface to a preset depth. Among them, the preset depth can be set according to actual needs. For example, when the height difference between the liquid surface of the liquid storage chamber and the outer edge of the chamber wall is 0.5 cm, the root of the toothbrush head can be controlled to be in contact with the liquid surface and immersed. The control module indirectly adjusts the amplitude of the toothbrush by controlling the power supply module to output different preset voltages. It can be understood that under the condition of a larger preset voltage, the amplitude of the toothbrush is larger, and the amount of liquid splashed out will also be larger. Therefore, by obtaining the amount of liquid splashed out of the liquid storage chamber, the working performance of the motor can be indirectly judged.

[0094] Furthermore, the electric toothbrush motor detection device includes a pressure detection module, and the pressure detection module is disposed below the sealed detection chamber. After the sealed detection chamber obtains a plurality of first liquid amounts splashed during the operation of the electric toothbrush motor, the method includes:

[0095] Based on the plurality of first liquid amounts, obtain a plurality of first pressure detection signals;

[0096] Based on the plurality of first pressure detection signals, a plurality of first working amplitudes are obtained;

[0097] After the sealed detection chamber obtains a plurality of second liquid amounts splashed by the operation of the electric toothbrush motor, the method includes:

[0098] Based on the plurality of second liquid amounts, a plurality of second pressure detection signals are obtained;

[0099] Based on the plurality of second pressure detection signals, a plurality of second working amplitudes are obtained.

[0100] In this embodiment, the pressure detection module can be implemented by a piezoelectric sensor, a capacitive sensor, etc. By arranging the pressure detection module below the sealed detection chamber, the weight of the sealed detection chamber can be detected. When the electric toothbrush motor drives the brush head to work and splashes the liquid in the liquid storage chamber into the sealed detection chamber, the weight of the sealed detection chamber changes.
