Technical Field

The invention relates to the field of control, in particular to a control method of an electric toothbrush.

Background

The electric toothbrush has high-efficiency nursing efficacy, can effectively improve the oral health, and is accepted by the public. As more and more brands and manufacturers have joined the electric toothbrush industry, the electric toothbrush technology is being pushed to update iteratively. At present, when a plurality of electric toothbrushes are used, due to the fact that a user exerts too much force due to personal reasons, a brush head is pressed on gum and teeth, a habit of using the electric toothbrushes with force is formed, on one hand, the cleaning effect is reduced, and on the other hand, due to the fact that external force and high-frequency vibration of the electric toothbrushes act simultaneously, corresponding parts of a human body can be damaged, for example, gum and oral membranes are damaged. In addition, most current electric toothbrushes do not have a splash-proof function, thereby causing the foam on the brush head to splash all around when in use.

Disclosure of Invention

The invention aims to solve at least one technical problem in the prior art and provides a control method of an electric toothbrush, which can avoid foams on a toothbrush head from splashing everywhere.

According to an embodiment of the present invention, there is provided a method for controlling an electric toothbrush, the method including:

the motor is used for driving the brush head to vibrate and is provided with a slight vibration mode and a normal vibration mode;

the sensor is used for detecting the stress applied to the motor;

the controller is respectively connected with the motor and the sensor and is used for controlling the motor to switch the operation mode according to the stress detected by the sensor;

the control method comprises the following steps:

the electric toothbrush is started initially, and the motor works in the slight vibration mode;

the sensor detects the stress applied to the motor in the slight vibration mode and records the stress as first detection pressure;

the controller continuously acquires the stress detected by the sensor, and controls the motor to be switched to the normal vibration mode if the stress detected by the sensor is larger than the first detection pressure by a first amplitude.

The control method provided by the embodiment of the invention at least has the following beneficial effects: the electric toothbrush is firstly operated in a slight vibration mode after being initialized and started, and is switched to a normal vibration mode after the stress detected by the sensor is increased to a certain extent, so that foams on the toothbrush head can be prevented from splashing everywhere before the toothbrush is started, and the splashing prevention function is realized; in addition, the sensor detects the stress of the motor in a slight vibration mode, records the stress as first detection pressure and serves as a comparison reference value, so that the stress can be updated every time the motor is used, and the stress cannot be influenced by permanent deformation of the electric toothbrush.

According to some embodiments of the invention, the control method further comprises:

the sensor detects stress applied to the motor in the normal vibration mode and records the stress as second detection pressure;

the controller continuously acquires the stress detected by the sensor, and controls the motor to be switched to the slight vibration mode if the stress detected by the sensor is smaller than the second detection pressure by a second amplitude.

Similarly, after the stress detected by the sensor is reduced by a certain amplitude, the electric toothbrush is switched from the normal vibration mode to the slight vibration mode, so that foams on the toothbrush head can be prevented from splashing everywhere after the toothbrush head is separated from teeth, and the splashing prevention function is realized; in addition, the sensor detects the stress applied to the motor in the normal vibration mode, and the stress is recorded as a second detection pressure and used as a comparison reference value, so that the stress can be updated every time the motor is used, and the motor can adapt to the use habit of a user.

According to some embodiments of the invention, the first amplitude is between twenty percent and fifty percent. The first amplitude is in a range of between twenty percent to fifty percent, and is neither too large nor too small.

According to some embodiments of the invention, the first amplitude is thirty percent.

According to some embodiments of the invention, the second amplitude is between twenty percent and fifty percent. The second amplitude is in the range of twenty to fifty percent and is neither too large nor too small.

According to some embodiments of the invention, the second amplitude is thirty percent.

According to some embodiments of the invention, the motor operates in the slight vibration mode at a lower vibration frequency than the normal vibration mode.

According to some embodiments of the invention, the motor operates in the slight vibration mode with a vibration amplitude lower than that of the normal vibration mode.

According to some embodiments of the invention, the controller stores a first pressure calibration and the controller issues an overpressure warning or takes an overpressure intervention if the stress detected by the sensor is greater than the first pressure calibration. The overpressure warning can remind the user of excessive force, so that the tooth brushing habit of the user is corrected, and the overpressure intervention measures can effectively avoid damage to gums or oral membranes. It will be appreciated that the over-voltage warning comprises an audible alarm and/or a light alarm

According to some embodiments of the invention, the overvoltage intervention measure comprises switching off the motor or reducing the vibration amplitude and/or the vibration frequency of the motor.
