In order to explain the technical solution described in the present invention, the following description will be made by way of specific embodiments.

Embodiment 1

As shown in FIG. 1, the first embodiment of the present invention provides a method for preventing foam splashing of an electric toothbrush, which can be applied to terminal devices such as electric toothbrushes and smart toothbrushes. The method for preventing splashing of an electric toothbrush foam provided by the embodiment includes:

Step S101: Acquire a first vibration amplitude of the motor in the electric toothbrush.

In a specific application, the acceleration can be obtained by a three-axis acceleration sensor or a three-axis gyro sensor provided in the electric toothbrush, or a six-axis attitude sensor or a nine-axis attitude sensor including a three-axis acceleration sensor or a three-axis gyro sensor. Data to obtain a first amplitude of vibration of the motor in the electric toothbrush.

Step S102: Determine whether the first vibration amplitude is greater than or equal to a first threshold.

In a specific application, after the first vibration amplitude of the motor is acquired, it is compared with a first threshold, and it is determined whether the electric toothbrush is affected by an external force by determining whether the acquired first vibration amplitude is greater than or equal to the first threshold. The first threshold value refers to the vibration amplitude of the motor when the electric toothbrush is in the normal brushing mode. It can be understood that the first threshold value is smaller than the initial vibration amplitude of the motor when the electric toothbrush is just started and not put into the user's mouth.

For example, when the electric toothbrush is newly activated but not put into the user's mouth, the initial vibration amplitude of the motor is 100A. When the electric toothbrush is placed in the user's mouth to perform the brushing action, the electric toothbrush generates friction with the user's teeth or the inner wall of the oral cavity. The situation, thereby hindering the vibration of the motor in the electric toothbrush, that is, the vibration amplitude of the motor at this time is smaller than the initial vibration amplitude, that is, when the user uses the electric toothbrush for the normal brushing action, the vibration amplitude of the motor in the electric toothbrush is bound to be It will be smaller than its initial vibration amplitude by 100A. Therefore, at this time, the first threshold when the electric toothbrush is in the normal brushing mode can be set to 80A according to actual conditions. It is to be understood that the description of the embodiments of the present invention is not to be construed as limiting.

Step S103: If the first vibration amplitude is greater than or equal to the first threshold, reduce the first vibration amplitude of the motor to a second threshold.

In a specific application, if the first vibration amplitude of the motor in the electric toothbrush is greater than or equal to the first threshold, it indicates that the vibration amplitude of the motor in the electric toothbrush is not affected by the external force or is affected by the external force, and the electric power can be judged at this time. The toothbrush is in the activated state and is not placed in the user's mouth by the user. When the electric toothbrush is in the activated state that is not placed in the user's mouth, the toothpaste or toothpaste foam on the electric toothbrush will splash around due to the vibration of the motor, affecting The user's use, therefore, in order to reduce the problem that the toothpaste or the toothpaste foam splashes around in the unbrushed state affects the user's use, in this embodiment, the vibration amplitude of the motor is lowered to a second threshold to make the electric toothbrush enter the anti-splash. Mode to avoid splashing around the toothpaste or toothpaste foam. It can be understood that the second threshold refers to the vibration amplitude of the motor when the electric toothbrush enters the brushing state and does not cause splashing of the toothpaste or the toothpaste foam.

In an embodiment, after the step S103, the method for preventing splashing of the electric toothbrush foam further comprises:

Step S201, acquiring a second vibration amplitude of the motor in the electric toothbrush;

Step S202, determining whether the second vibration amplitude is less than a second threshold;

Step S303, if the second vibration amplitude is less than the second threshold, increasing a second vibration amplitude of the motor to the first threshold.

In a specific application, if the second vibration amplitude of the motor in the electric toothbrush is less than the second threshold, the electric toothbrush in the anti-splash mode is placed in the user's mouth by the user at the time, because the user's mouth is placed. The latter electric toothbrush may generate friction or the like between the user's teeth or the inner wall of the oral cavity, which hinders the vibration of the motor in the electric toothbrush, so that the second vibration amplitude of the motor at this time is smaller than the second threshold value in the anti-splash mode. When the electric toothbrush in the anti-splash mode is placed in the user's mouth by the user, it means that the user is currently brushing the teeth, so in order to ensure that the user can brush the teeth normally, the second vibration amplitude of the motor in the electric brushing should be increased, that is, the motor is The vibration amplitude is increased to a first threshold of the normal brushing mode to restore the normal brushing mode of the electric toothbrush, so that the user can brush the teeth normally.

For example, the second threshold determined according to the actual situation is 60A, that is, when the vibration amplitude of the motor is 60A, the vibration of the electric brushing teeth is small, and the toothpaste or the toothpaste foam in the electric toothbrush is not splashed, but the oral cavity cannot be cleaned. The purpose is to enter the anti-splash mode, that is, when the electric toothbrush is in the anti-splash mode, the vibration amplitude of the motor in the electric toothbrush can be 60A. When the electric toothbrush in the anti-splash mode is placed in the oral cavity by the user to perform the brushing action, the friction generated between the electric toothbrush and the user's teeth or the inner wall of the oral cavity further reduces the vibration amplitude of the motor, so that the motor in the electric toothbrush at this time The vibration amplitude is less than 60A, which makes it impossible to clean the teeth of the mouth. Therefore, when it is detected that the vibration amplitude of the motor in the electric toothbrush is less than the second threshold value 60A, the vibration amplitude of the motor should be increased to the first threshold value 80A of the normal brushing mode, so that the user can normally clean the teeth and the oral cavity through the electric toothbrush. .

In one embodiment, the method for preventing splashing of an electric toothbrush foam further comprises:

Detecting a pressure of the electric toothbrush;

If the pressure is lower than a preset pressure threshold, determining that the electric toothbrush is under excessive pressure;

The electric toothbrush is controlled to reduce low vibration frequency and vibration intensity.

In a specific application, according to the pressure sensor detecting the pressure of the electric toothbrush, if the pressure of the electric toothbrush is detected to be lower than a preset pressure threshold, then the pressure on the inner wall or the tooth of the user to the electric toothbrush is too large, so that Causes the life of the electric toothbrush to decrease, or cause tooth wear and injury. Therefore, the electric toothbrush should be controlled to reduce the vibration frequency and the vibration force, or the motor of the electric toothbrush is controlled to reduce the rotation speed or stop the operation, and the electric toothbrush is prevented from being damaged by an external force. At this time, it is also possible to set the prompt light or set the ringtone to prompt the user that the current external force of the electric toothbrush exceeds the tolerance range of the electric toothbrush, so that the user reduces the force applied to the electric toothbrush.

According to the embodiment, the vibration amplitude of the motor in the electric toothbrush is obtained, and whether the vibration amplitude is affected by the external force is determined, thereby determining whether the electric toothbrush is in a brushing state, and when the electric toothbrush is not in the brushing state, reducing the vibration amplitude of the motor to reduce The phenomenon of toothpaste or toothpaste foam splash on the electric toothbrush enhances the user experience.

Although the above describes only the manner in which the first vibration amplitude of the motor is obtained, it can be understood that the second vibration amplitude of the motor can also be obtained by the above-described acquisition method.

In this embodiment, a first preset correspondence relationship between the acceleration amplitude and the first vibration amplitude of the motor is first established, and then the acceleration waveform map is obtained by analyzing the acceleration data to determine the acceleration amplitude of the motor according to the acceleration waveform diagram, thereby The first vibration amplitude of the motor is obtained according to a preset correspondence relationship between the acceleration amplitude of the motor and the first vibration amplitude of the motor.

In an embodiment, the step S101 further includes:
