For the purpose of facilitating understanding of the embodiments of the present application, the following description will be made in terms of specific embodiments with reference to the accompanying drawings, which are not intended to limit the embodiments of the present application.

Example 1

There is provided a method of controlling a power toothbrush, referring to fig. 1.

A first pressure for pressing the first key is obtained.

The first pressure is a continuous pressure other than 0.

The first key is used for controlling the vibration intensity of the electric toothbrush head.

And generating a first control instruction according to the first pressure of the first key, wherein the first control instruction controls the force of a motor of the electric toothbrush to change along with the change of the first pressure.

The first control instruction comprises that the power of the motor of the electric toothbrush is adjusted to a first power.

Preferably, the first force is a value of a lowest force allowed by a motor of the electric toothbrush.

Specifically, after the first pressure of the first key is received, the force of the motor of the electric toothbrush is controlled to be adjusted to the value of the lowest force allowed by the motor.

The first control instruction comprises that the force for controlling the motor of the electric toothbrush is changed along with the change of the first pressure from the first force.

The initial value of the force of the motor of the electric toothbrush is the first force.

Preferably, the force of the motor of the electric toothbrush increases with an increase in the first pressure with the first force as an initial value.

It should be noted that, all that the power of the motor of the electric toothbrush changes with the change of the first pressing signal is within the protection scope of the present patent, including that the power of the motor of the electric toothbrush decreases with the increase of the first pressing signal, and the power of the motor of the electric toothbrush increases with the increase of the first pressing signal.

The force of the motor is increased from the first force to a second force under the control of the first control instruction.

Ways to adjust the force of the motor of the electric toothbrush include, but are not limited to, changing the power of the motor and changing the operating frequency of the motor.

The power of the motor is changed, and the power supply voltage of the motor is increased or reduced under the condition that the driving signal is not changed, so that the power of the motor is correspondingly increased or reduced; similarly, the duty cycle of the drive signal may be increased or decreased with a constant motor supply voltage, and the power of the motor may be increased or decreased accordingly.

The change of the operating frequency of the motor may also be considered as a change of the rotational speed of the motor. By varying the frequency of the drive signal. Generally, the force of the electric toothbrush brush head changes along with the change of the working frequency of the motor, part of the force of the electric toothbrush brush head decreases along with the increase of the frequency of the motor, and part of the force of the electric toothbrush brush head increases along with the increase of the frequency of the motor. The effect of adjusting the force of the brush head is achieved by changing the working frequency of the motor.

Illustratively, the first pressure of the first key is received, the first pressure is not 0, the user presses the first key and keeps a pressed state, and the power of the motor of the electric toothbrush is adjusted to the first power.

In one possible embodiment of the present invention, the power of the motor of the electric toothbrush is adjusted by changing the power of the motor. The motor drives the brush head of the electric toothbrush to vibrate, when the output power of the electric toothbrush reaches the maximum, the vibration force of the brush head is recorded as 100%, the vibration force of the brush head under the first force of the motor is recorded as 10%, and the default vibration force of the brush head is 50% when the electric toothbrush leaves a factory. When the electric toothbrush is turned on to start working, the vibration strength of the brush head is 50% of the default vibration strength, if the brushing strength is adjusted, the first key is continuously pressed, when the first key is pressed, the vibration strength of the brush head is changed to 10%, pressure is applied to the first key, and the vibration strength of the brush head is increased along with the increase of the applied pressure. For example, a pressure of 200gf is applied to the first button, and the vibration force of the brush head becomes 40%. If the force at the moment still can not reach the requirement, pressure is continuously applied to the first key, the pressure is increased to 300gf, and the vibration force of the brush head is changed to 60%. By analogy, when the pressure applied to the first key is increased to 400gf, the vibration strength of the brush head is 80%, and when the pressure applied to the first key is increased to 500gf, the vibration strength of the brush head is 100%. And in the whole operation process, the first key is always pressed.

In another possible embodiment of the present invention, the power of the electric toothbrush is adjusted by changing the rotational speed of the motor. The motor drives the brush head of the electric toothbrush to vibrate, the higher the rotating speed of the motor is, the larger the vibration force of the brush head is, the lowest rotating speed allowed by the motor is 8000rpm, and the default rotating speed when the electric toothbrush leaves a factory is 16000 rpm. When the electric toothbrush is turned on to start working, the rotating speed of the motor is 16000rpm, if the first key is continuously pressed to adjust the tooth brushing strength, the rotating speed of the motor is 8000rpm, and the rotating speed of the motor is increased along with the increase of the pressure applied to the first key. For example, a pressure of 300gf is applied to the first button, and the rotation speed of the motor is 17600 rpm. If the force of the motor driving the brush head cannot meet the requirement, pressure is continuously applied to the first key, the pressure is increased to 400gf, and the rotating speed of the motor is 20800 rpm. By analogy, when the pressure applied to the first key is increased to 500gf, the rotation speed of the motor is 24000 rpm. And in the whole operation process, the first key is always pressed.

When the first pressure is removed, the force of the motor is kept constant at the second force.

Further, when the first pressure becomes 0, the force of the motor is kept constant at the second force.

In one possible embodiment of the present invention, the power of the motor of the electric toothbrush is adjusted by changing the power of the motor. The electric toothbrush adjusts the force of the motor through the first control command, and the motor drives the brush head of the electric toothbrush to vibrate. For example, when the pressure applied to the first button is 400gf and the vibration force of the brush head becomes 80%, it is sufficient that if tooth cleaning is desired with the vibration force, the brush head of the electric toothbrush continues to operate with the vibration force of 80% when the first pressure is removed.

In another possible embodiment of the present invention, the power of the electric toothbrush is adjusted by changing the rotational speed of the motor. The motor drives the brush head of the electric toothbrush to vibrate, and the higher the rotating speed of the motor is, the larger the vibration force of the brush head is. The electric toothbrush adjusts the force of the motor through the first control command, and the motor drives the brush head of the electric toothbrush to vibrate. For example, when the pressure applied to the first button is 400gf and the rotation speed of the motor is 20800rpm, it is sufficient that the pressure applied to the first button is removed and the motor of the brush head of the electric toothbrush continues to operate at 20800rpm in the case where it is desired to clean the teeth with the vibration power.

And acquiring a second pressure of the first key when the first pressure is changed to 0.

Further, when the first key is pressed again after the first pressure is removed, a second pressure of the first key is obtained.

The second pressure is a continuous pressure other than 0.

The first key is used for controlling the vibration intensity of the electric toothbrush head.

And generating a second control instruction according to the second pressure of the first key, wherein the second control instruction controls the force of the motor of the electric toothbrush to change along with the change of the second pressure from the first force.

Preferably, the force of the motor of the electric toothbrush increases with the increase of the second pressure with the first force as an initial value.

The second control instruction has the same control effect as the first control instruction.

In one possible embodiment of the present invention, the power of the motor of the electric toothbrush is adjusted by changing the power of the motor. Using the electric toothbrush for tooth cleaning, the first button is pressed last time until the first pressure is removed, the pressure applied to the first button by the user is 400gf, and the vibration force of the brush head becomes 80%. When the electric toothbrush is used, if the user thinks that the 80% vibration strength can not meet the requirement of the user, the user presses the first key again, namely the electric toothbrush obtains the second pressure of the first key, the strength of the motor is adjusted again, and the motor is increased along with the increase of the pressure for pressing the first key from the first strength again.

In another possible embodiment of the present invention, the power of the electric toothbrush is adjusted by changing the rotational speed of the motor. The electric toothbrush is used for cleaning teeth, the first key is pressed for the last time until the first pressure is removed, the pressure applied to the first key by a user is 400gf, the rotating speed of the motor is 20800rpm, and in the using process, the user presses the first key again when considering that the rotating speed of the motor at 20800rpm cannot meet the requirement of the user, namely the electric toothbrush obtains the second pressure of the first key, the power of the motor is adjusted again, and the motor is increased along with the increase of the pressure for pressing the first key from the first power.

During the period when the first pressure is removed and the second force is not obtained, the force when the motor works is kept constant at the second force.

Further, the above situation includes that when the first pressure on the first button is removed and the electric toothbrush is turned off, the electric toothbrush is turned on again and the second pressure is not obtained, the force of the motor is still kept unchanged at the second force.

In an exemplary mode, when the electric toothbrush is used for the last time, the strength of the motor is adjusted through the first key, so that the vibration strength of the toothbrush head is 80%, and the electric toothbrush is turned off after use. When the electric toothbrush is started again, the force of the motor is consistent with the force used last time, namely after the electric toothbrush is started this time, the vibration force of the brush head still keeps 80 percent unchanged.

Example 2

A control device is provided, see fig. 2.

The control device comprises a first pressure obtaining module, a first pressure obtaining module and a controller.

The first pressure obtaining module can obtain first pressure for pressing the first key.

The first key is used for controlling the vibration intensity of the electric toothbrush head.

And the second pressure obtaining module is used for obtaining second pressure for pressing the first key when the first pressure is changed into 0.

The second pressure is a continuous pressure other than 0.

The first key is used for controlling the vibration intensity of the electric toothbrush head.

The controller generates a first control instruction according to the first pressure of the first key, and the first control instruction controls the force of the motor of the electric toothbrush to change along with the change of the first pressure from the first force; and generating a second control instruction according to the second pressure of the first key, wherein the second control instruction controls the force of the motor of the electric toothbrush to change along with the change of the second pressure from the first force.

Specifically, the first control instruction and the second control instruction can control the strength of the motor of the electric toothbrush to increase from the first strength with the increase of the first pressure.

During the period when the first pressure is removed and the second force is not obtained, the force when the motor works is kept constant at the second force.

Further, when the first pressure on the first key is removed and the electric toothbrush is turned off, the electric toothbrush is turned on again and the second pressure is not obtained, the force of the motor is still kept unchanged at the second force.

Example 3

The present embodiment provides a power toothbrush.

The electric toothbrush comprises a brush head and a brush handle, wherein a first key is arranged on the brush handle.

The first button increases the vibration strength of a motor in the electric toothbrush during tooth brushing.

When the electric toothbrush is not operated, the user presses the first button with the first pressure, and the electric toothbrush does not produce any effect. When the electric toothbrush is in operation, a user continuously presses the first key with a first pressure, the controller sends a first control instruction, the function of enhancing the brushing strength of the electric toothbrush is activated, and the motor operates with the first force and is increased along with the increase of the degree of pressing pressure. When the second force degree of the motor increased from the first force degree can meet the requirement of a user, the first pressure on the first key is removed, and the motor keeps the second force degree unchanged and continues to work. And when the first key is pressed by the second pressure, the electric toothbrush repeats the process.

The electrical parameter is monitored and transmitted to a control unit of the electric toothbrush to characterize the magnitude of the pressing pressure.

Preferably, an elastic device is arranged below the first key, a permanent magnet is arranged on the elastic device, a hall sensor is fixedly arranged at a position opposite to the permanent magnet, and when the first key is pressed by the pressure, the position of the permanent magnet changes along with the pressing, so that the magnetic flux of the hall sensor changes correspondingly. Transmitting the value of the Hall sensor to a control unit of the electric toothbrush to represent the magnitude of the pressing pressure.

The controller receives the first pressure transmitted by the module with the sensing function, and controls the motor to increase along with the increase of the first pressure from the first force. When the first pressure is not sensed, namely the first key is not pressed any more, the controller controls the motor to work with the increased motor force.

It should be noted that when the electric toothbrush is turned on to work, the motor of the electric toothbrush will work with the motor strength adjusted at the previous time, and if the user has a requirement for adjusting the motor strength, the first button is pressed with the second pressure, so that the motor is adjusted from the first strength.
