Example one

Fig. 1 shows a flow chart of an implementation of an adaptive control method for a power toothbrush according to an embodiment of the present invention, in which a 3D sensor 30 (see embodiment seven in detail) is disposed in parallel with a direction of a handle 20 (or hereinafter, may also be referred to as a handle 20) of the power toothbrush, and the method includes the following steps:

in step S101, when the handle 20 senses a touch signal, the direction angle of the electric toothbrush handle 20 is obtained.

In the embodiment of the present invention, a sensing button or sensing area may be disposed on the electric toothbrush handle 20 to obtain a touch operation such as a hand-holding operation of the electric toothbrush handle 20 by a user.

In the present embodiment, the orientation angle of the electric toothbrush handle 20 includes an angle when the electric toothbrush handle 20 is erected, an angle when the electric toothbrush handle 20 is laid flat, an angle when the electric toothbrush handle 20 is laid on a side, and an angle when the electric toothbrush handle 20 is inclined.

Example two

Referring to fig. 5, on the basis of the first embodiment, the step S101 specifically includes:

in step S201, sensing parameters of the electric toothbrush are acquired.

In one embodiment of the present invention, the sensing parameter of the electric toothbrush ranges from 0 to 200, which is determined by the type of the 3D sensor 30 built in the electric toothbrush.

In the embodiment of the present invention, the sensed parameters of the electric toothbrush include sensed parameter values (i.e., sensed quantity) in the Y-axis direction (the direction parallel to the handle 20 of the electric toothbrush) and sensed parameter values in the Z-axis direction (the direction perpendicular to the handle 20 of the electric toothbrush).

In step S202, the orientation angle of the handle 20 of the electric toothbrush is determined based on the sensed parameters of the electric toothbrush.

(see the third example for details)

In one embodiment of the present invention, when the sensed values of the electric toothbrush are 0 in both the Y axis and the Z axis, the direction angle of the electric toothbrush handle 20 is determined as the angle when the electric toothbrush handle is placed on the side.

As an embodiment of the present invention, when the sensed values of the electric toothbrush in the Y axis and the Z axis are 10 and 35, respectively, the direction angle of the electric toothbrush handle 20 is determined as the angle when the electric toothbrush handle is tilted.

According to the self-adaptive control method of the electric toothbrush provided by the embodiment of the invention, the induction parameters of the electric toothbrush are firstly obtained, and then the direction angle of the brush holder 20 of the electric toothbrush is determined according to the induction parameters of the electric toothbrush, so that different direction angles corresponding to different working modes of the electric toothbrush are realized, the electric toothbrush can be automatically switched to different working modes according to the direction angles, and the electric toothbrush is more intelligent.

EXAMPLE III

On the basis of the second embodiment, the step S202 specifically includes:

when the sensed quantity in a direction parallel to the electric toothbrush handle 20 reaches a first sensing threshold, the direction angle of the electric toothbrush is determined as the angle when the electric toothbrush handle 20 is standing up.

In embodiments of the present invention, the first sensing threshold may be 100, 120, 150, 200, etc., depending on the model of the 3D sensor 30 built into the handle 20 of the electric toothbrush. That is, when the sensing amount in the direction (Y axis direction) parallel to the electric toothbrush handle 20 reaches a certain threshold, the direction angle of the electric toothbrush can be determined as the angle when the electric toothbrush handle 20 is erected.

For example, a first sensing threshold of 100 for a powered toothbrush parallel to its handle 20 and a maximum sensing level of 120 parallel to its handle 20 may indicate that the powered toothbrush is upright (as shown in fig. 2) when the sensing level in the direction parallel to its handle 20 reaches the maximum sensing level of 120, and that the sensing level in the direction parallel to its handle 20 reaches 100 may indicate that the powered toothbrush is at an angle of 30 ° to the Y-axis when it is upright. It will be appreciated that when the sensed value of the electric toothbrush in a direction parallel to its handle 20 is between the first sensing threshold and the maximum sensed value, it is indicated that the electric toothbrush is in a position having an included angle with the Y-axis when in its upright position, the included angle being in the range of 0 ° to 30 °, within which range the electric toothbrush is considered to be in an upright position.

On this basis, the step S102 specifically includes:

when the direction angle of the electric toothbrush is the angle when the electric toothbrush handle 20 is erected, the corresponding working mode of the electric toothbrush is a standby or charging mode.

In the embodiment of the present invention, when the direction angle of the electric toothbrush is the angle when the handle 20 of the electric toothbrush is erected, it indicates that the electric toothbrush is in a standby state or a charging state, and accordingly, the operation mode of the electric toothbrush is activated as a standby or charging mode.

In another embodiment of the present invention, on the basis of the second embodiment, the step S202 specifically includes:

when the sensed quantity in the direction perpendicular to the handle 20 reaches a second sensing threshold, the direction angle of the electric toothbrush is determined as the angle at which the handle 20 lies flat.

In embodiments of the present invention, the second sensing threshold may be 50, 80, 100, 110, 120, etc., depending on the model of the 3D sensor 30 built into the handle 20 of the electric toothbrush. That is, when the sensing amount in the direction (Z-axis direction) perpendicular to the handle 20 of the electric toothbrush reaches a certain threshold, the direction angle of the electric toothbrush can be determined as the angle when the handle 20 of the electric toothbrush is laid flat.

For example, a second sensing threshold of 80 for a toothbrush perpendicular to its handle 20 and a maximum sensing level of 100 perpendicular to its handle 20 may be defined as 100, when the sensing level of 100 perpendicular to its handle 20 is defined as 100, the toothbrush is in a horizontal position (as shown in fig. 3), and when the sensing level of 80 perpendicular to its handle 20 is defined as 10 ° from the Y-axis of the toothbrush in the horizontal position. It will be appreciated that when the sensed level of the electric toothbrush in a direction perpendicular to its handle 20 is between the second sensing threshold and the maximum sensed level, it is indicated that the electric toothbrush is in a position having an included angle with the Y-axis when it is in its horizontal position, the included angle being in the range of 0 ° to 10 °, and the included angle is considered to be the angle of the electric toothbrush when it is in a flat position.

On this basis, the step S102 specifically includes:

when the direction angle of the electric toothbrush is the angle when the brush holder 20 of the electric toothbrush is laid flat, the corresponding working mode of the electric toothbrush is a powerful cleaning mode.

In the embodiment of the present invention, when the direction angle of the electric toothbrush is the angle when the electric toothbrush handle 20 is laid flat, it generally means that the electric toothbrush is in a state of cleaning the user's large teeth, i.e. the toothbrush head faces the direction of gravity or faces away from the direction of gravity, and therefore, it is necessary to control the operation mode of the electric toothbrush to be the powerful cleaning mode in order to better clean the teeth.

In another embodiment of the present invention, on the basis of the second embodiment, the step S202 specifically includes:

when the induction quantity in the direction parallel to the electric toothbrush handle 20 and the induction quantity in the direction vertical to the electric toothbrush handle 20 are both 0, the direction angle of the toothbrush is determined as the angle when the electric toothbrush handle 20 is placed on the side.

Referring also to fig. 4, in the present embodiment, the angle of the electric toothbrush handle 20 when it is placed on its side is 0 to 2 (including 0) with the Y-axis angle of the electric toothbrush handle 20 in its horizontal position, and the toothbrush head faces toward or away from the user's face. It will be appreciated that the 1-2 range is provided to allow for a 2 tolerance in view of the fact that the user is fully horizontal while not fully holding the head toward the face during use of the power toothbrush.

On this basis, the step S102 specifically includes:

when the direction angle of the electric toothbrush is the angle when the electric toothbrush handle 20 is placed on the side, the corresponding working mode of the electric toothbrush is the soft cleaning mode.

In the embodiment of the present invention, when the electric toothbrush handle 20 is placed on its side, indicating that the user is in a state of brushing incisors, the electric toothbrush is controlled to operate in a gentle cleaning mode for better maintenance of dental health.

In another embodiment of the present invention, on the basis of the second embodiment, the step S202 specifically includes:

when the sensed quantity in the direction parallel to the electric toothbrush handle 20 and the sensed quantity in the direction perpendicular to the electric toothbrush handle 20 can be detected, the direction angle of the electric toothbrush is determined as the angle when the electric toothbrush handle 20 is obliquely placed.

In the embodiment of the present invention, when the sensed quantity in the direction parallel to the handle 20 of the electric toothbrush and the sensed quantity in the direction perpendicular to the handle 20 of the electric toothbrush can be detected, it indicates that the electric toothbrush has sensed quantities in both the Y axis and the Z axis, and indicates that the electric toothbrush is in a tilted state, such as when a user brushes the outer wall or the inner wall of the two big teeth.

It will be appreciated that the angle at which the handle 20 of the powered toothbrush is tilted is generally between the Y-axis in its upright position and the Y-axis in its horizontal position.

On this basis, the step S102 specifically includes:

when the direction angle of the electric toothbrush is the angle when the electric toothbrush handle 20 is obliquely placed, the corresponding working mode of the electric toothbrush is the quick cleaning mode.

In the embodiment of the invention, when the direction angle of the electric toothbrush is the angle when the electric toothbrush handle 20 is obliquely placed, the electric toothbrush is in an obliquely placed state, and a user is in a state of brushing the outer walls or the inner walls of the large teeth on two sides, the electric toothbrush is controlled to carry out a rapid cleaning mode, so that the user can rapidly and efficiently clean the outer walls or the inner walls of the large teeth on two sides.

In the embodiment of the present invention, when the direction angle of the electric toothbrush is the angle when the electric toothbrush handle 20 is laid flat, it generally means that the electric toothbrush is in a state of cleaning the user's large teeth, i.e. the toothbrush head faces the direction of gravity or faces away from the direction of gravity, and therefore, it is necessary to control the operation mode of the electric toothbrush to be the powerful cleaning mode in order to better clean the teeth.

In another embodiment of the present invention, on the basis of the fifth embodiment, the position status determining module 312 specifically includes:

and the third angle determination submodule is used for determining the direction angle of the toothbrush as the angle when the electric toothbrush handle 20 is laterally placed when the induction quantity in the direction parallel to the electric toothbrush handle 20 reaches the induction quantity in the direction vertical to the electric toothbrush handle 20 which is 0.

When the induction quantity in the direction parallel to the electric toothbrush handle 20 and the induction quantity in the direction vertical to the electric toothbrush handle 20 are both 0, the direction angle of the toothbrush is determined as the angle when the electric toothbrush handle 20 is placed on the side.

Referring also to fig. 4, in the present embodiment, the angle of the electric toothbrush handle 20 when it is placed on its side is 0 to 2 (including 0) with the Y-axis angle of the electric toothbrush handle 20 in its horizontal position, and the toothbrush head faces toward or away from the user's face. It will be appreciated that the 1-2 range is provided to allow for a 2 tolerance in view of the fact that the user is fully horizontal while not fully holding the head toward the face during use of the power toothbrush.

At this time, the operation mode determining unit 320 specifically includes:

and the soft cleaning mode determining module is used for determining that the corresponding working mode of the electric toothbrush is a soft cleaning mode when the direction angle of the electric toothbrush is the angle when the electric toothbrush handle 20 is laterally placed.

In the embodiment of the present invention, when the electric toothbrush handle 20 is placed on its side, indicating that the user is in a state of brushing incisors, the electric toothbrush is controlled to operate in a gentle cleaning mode for better maintenance of dental health.

In another embodiment of the present invention, on the basis of the fifth embodiment, the position status determining module 312 specifically includes:

and the fourth angle determination submodule is used for determining the direction angle of the electric toothbrush as the angle when the electric toothbrush handle 20 is obliquely placed when the induction quantity in the direction parallel to the electric toothbrush handle 20 reaches the induction quantity which can be detected in the direction vertical to the electric toothbrush handle 20.

In the embodiment of the present invention, when the sensed quantity in the direction parallel to the handle 20 of the electric toothbrush and the sensed quantity in the direction perpendicular to the handle 20 of the electric toothbrush can be detected, it indicates that the electric toothbrush has sensed quantities in both the Y axis and the Z axis, and indicates that the electric toothbrush is in a tilted state, such as when a user brushes the outer wall or the inner wall of the two big teeth.

It will be appreciated that the angle at which the handle 20 of the powered toothbrush is tilted is generally between the Y-axis in its upright position and the Y-axis in its horizontal position.

At this time, the operation mode determining unit 320 specifically includes:

and the quick cleaning mode determining module is used for determining that the working mode corresponding to the electric toothbrush is the quick cleaning mode when the direction angle of the electric toothbrush is the angle of the electric toothbrush handle 20 when the electric toothbrush is obliquely placed.

In the embodiment of the invention, when the direction angle of the electric toothbrush is the angle when the electric toothbrush handle 20 is obliquely placed, the electric toothbrush is in an obliquely placed state, and a user is in a state of brushing the outer walls or the inner walls of the large teeth on two sides, the electric toothbrush is controlled to carry out a rapid cleaning mode, so that the user can rapidly and efficiently clean the outer walls or the inner walls of the large teeth on two sides.
