S60: the input voltage of the conveying drive motor enters the integration circuit;

S70: receiving a real-time output current of the driving motor;

S80: screening real-time output current;

S90: Read the pressure value corresponding to the real-time output current in the mapping database.

The toothbrush described above is a smart toothbrush, and the toothbrush head of the toothbrush may include an ultrasonic vibration and/or rotating structure. Since the load of the drive motor is larger when the voltage supplied to the drive motor is constant, the output current value of the drive motor is larger, that is, the pressure generated during the use of the toothbrush is proportional to the current of the drive motor. In one embodiment, the switch of the toothbrush is opened by a button or a touch sensing method, so that the power source in the toothbrush communicates with the driving motor, the driving motor starts to drive the brush head, and the controller in the toothbrush starts to receive the input voltage of the driving motor in real time. The input voltage can be filtered and analyzed, and the input voltage is passed through the integration circuit, that is, the input voltage is passed through the waveform transformation, the cancellation of the offset voltage of the amplification circuit or the integral compensation in the feedback control, so that the drive motor obtains a more stable input. The voltage does not affect the real-time current value of the drive motor. Further, the controller can synchronously receive the real-time output current of the driving motor, and calculate and filter the real-time output current through a software filtering algorithm in the controller, which can eliminate the abnormal value of the output current to obtain more accurate real-time. The output current is used to obtain a more accurate pressure value. Further, a mapping database of the analog output current and the corresponding pressure value is stored in the controller, wherein the analog output current is a current value of the driving motor corresponding to the pressure generated by the toothbrush on the tooth according to the toothbrush during use. According to the accurate and reasonable value obtained by multiple sampling and processing, the controller searches the mapping database through the more accurate real-time output current after processing, reads the accurate corresponding pressure value, and finally displays through the display on the toothbrush. The driving motor real-time output current corresponding to the pressure value, so as to facilitate more accurate use guidance for the user, and the entire reading current and processing process are processed and calculated by the controller, without using a pressure sensor or a pressure sensor, etc. The detecting device can also reduce the manufacturing cost and facilitate the miniaturization of the toothbrush production.

The technical scheme of the invention sequentially enters the integration circuit by inputting the input voltage of the driving motor, and filters the real-time output current, and then reads the pressure value corresponding to the real-time output current in the mapping database, thereby improving the corresponding pressure value by detecting the current. The detection accuracy is not required to use a detecting device such as a pressure sensor or a pressure sensor, which can reduce the manufacturing cost and make the smart toothbrush smaller.

This makes it easy for the user to confirm the problem and process as soon as possible to ensure the stable use of the toothbrush.

Referring to FIG. 3, preferably, S80: screening the real-time output current further includes the following steps:

S81: establishing a current threshold;

S82: Determine whether an output current corresponding to each time node is located in the current threshold, and if so, collect an output current corresponding to the time node.

Since the current is continuous, and some current values may be abnormal due to external factors, by setting a current threshold, the abnormal current value can be filtered, the influence of the abnormal current value on the post-processing and the obtained voltage value is eliminated, and the detection accuracy is improved. . And the controller determines that the output current corresponding to each time node is located in the current threshold, the controller collects the output current value corresponding to each time node, and performs judgment processing, and the controller performs the collection process to obtain the corresponding accurate pressure value. When the output current value is not within the current threshold, the culling can be directly performed to improve the calculation accuracy of the pressure value.

Referring to FIG. 4, preferably, S30: before starting the switch of the toothbrush, the following steps are further included:

S10: storing a pressure data model,

S20: Establish a mapping database of the pressure data model and the output current.

In one embodiment, the toothbrush stores or updates the mapping database in advance, wherein the pressure data model is a pressure range value detected according to a plurality of simulation experiments on the toothbrush, and the pressure range value is divided into uniform nodes. The output current of the corresponding drive motor is obtained for each pressure node as a mapping database. In this way, the controller directly detects the change of the current of the driving motor to obtain the corresponding pressure change, and does not require an additional detecting device, which is simpler and more convenient.
