Next, in connection with fig. 1, a control method of an electric toothbrush according to an exemplary embodiment of the present application will be described by taking an example in which the control method of an electric toothbrush is applied to an electric toothbrush. Referring specifically to fig. 2, a schematic flow chart of a control method of an electric toothbrush according to an embodiment of the present application is shown. As shown in fig. 2, the control method of the electric toothbrush comprises the following steps:

s201, the current oral cleaning position of the brush head is identified.

In particular, when a user uses the electric toothbrush for oral cleaning, the position identifier of the electric toothbrush may, but is not limited to, determine a current oral cleaning position corresponding to the electric toothbrush head based on current motion data of the electric toothbrush currently acquired. The motion data may include, but is not limited to, a roll amplitude, a movement amplitude, etc. of the electric toothbrush.

S202, if the current oral cavity cleaning position is the first position, the motor is controlled to drive the brush head to swing according to the first parameter.

Specifically, if the position identifier identifies that the current oral cavity cleaning position corresponding to the brush head is the first position, the motor can be directly controlled to drive the brush head to swing according to the first parameter corresponding to the first position.

And S203, if the current oral cavity cleaning position is the second position, controlling the motor to drive the brush head to swing according to the second parameter.

Specifically, if the position identifier identifies that the current oral cavity cleaning position corresponding to the brush head is the second position, the motor can be directly controlled to drive the brush head to swing according to the second parameter corresponding to the second position. The first parameter and the second parameter are different.

Optionally, the first position and the second position are two adjacent tooth surfaces or tooth areas. All oral cleaning positions of the user comprise at least two dental zones comprising at least two dental surfaces.

Illustratively, as shown in fig. 3, all oral cleaning positions of the user may include 6 zones of upper left tooth zone 310, upper middle tooth zone 320, upper right tooth zone 330, lower left tooth zone 340, lower middle tooth zone 350, lower right tooth zone 360. Wherein, the upper left tooth area 310, the upper right tooth area 330, the lower left tooth area 340, and the lower right tooth area 360 may each include 3 tooth surfaces of an outer tooth surface 370, an occlusal surface 380, and an inner tooth surface 390; the upper middle dental region 320 and the lower middle dental region 350 may each include 2 facets, an outer side 370 and an inner side 390.

According to the embodiment of the application, for different current oral cavity cleaning positions, the brush head is driven by the motor to present different swinging modes according to different parameters, namely, when the current oral cavity cleaning position is switched, the electric toothbrush presents different oral cavity cleaning modes, on one hand, the problem that a user cannot form oral cavity cleaning aiming at a tooth surface state by adopting the same oral cavity cleaning method at different oral cavity cleaning positions can be solved; on the other hand, some users can adopt the tongue brushing side or the cheek brushing side to incline the brush head to clean the occlusal surface along with the way when cleaning the oral cavity due to the problem of oral cavity cleaning habit, the current oral cavity cleaning position is identified, when the current oral cavity cleaning position is identified to change, the brush head is driven by the control motor to generate obvious change swing modes with different parameters, a certain prompt can be formed for the users, or the change of the swing modes of the brush head can be driven by the control motor with different parameters to form compensation for the nonstandard postures.

In some possible embodiments, the first parameter includes a first frequency and a first duty cycle, and the second parameter includes a second frequency and a second duty cycle. The first frequency is different from the second frequency and/or the first duty cycle is different from the second duty cycle.

In this embodiment of the present application, at least one of the swing frequency and the duty cycle of the motor is different under first parameter and second parameter, realizes that electric toothbrush's brush head is when switching to different oral cavity cleaning position, changes swing amplitude and/or the swing speed of brush hair on the brush head through the change of control motor's swing frequency and/or duty cycle, realizes effectively reminding the user that current oral cavity cleaning position has changed to a certain extent to the user in time adjusts oral cavity cleaning gesture according to this change, improves user's clean effect in oral cavity.

In some possible embodiments, the first location is adjacent to the second location, the first parameter is a constant parameter, and the second parameter is a variable parameter. The constant parameter is a parameter with a fixed frequency and duty ratio, and the variable parameter is a parameter with a variable frequency and/or duty ratio.

In this application embodiment, through the motor of control in two adjacent oral cavity cleaning positions department one with fixed definite parameter drive brush head swing, and another with the variable parameter drive brush head swing that changes for the swing mode of brush head can produce more obvious change, further reinforcing reminds the user that the current oral cavity cleaning position has changed effect.

Optionally, when the first position is adjacent to the second position, the variable parameter is a parameter that varies within a first parameter range, and the fixed parameter is not within the first parameter range. According to the embodiment of the application, when the current oral cavity cleaning position of the brush head is the first position, the motor is controlled to drive the brush head to swing through the variable parameter which changes in the first parameter range, and when the current oral cavity cleaning position of the brush head is the second position adjacent to the first position, the motor is controlled to drive the brush head to swing through the fixed parameter which does not change in the first parameter range, so that an omnibearing swing mode is formed, and the illusion that the fixed parameter causes the user to generate the first position and the second position to be the same position in the variable range of the variable parameter is avoided.

Optionally, when the first position is adjacent to the second position, the variable parameter may be a parameter that varies back and forth with a plurality of values, where the plurality of values are different, and the fixed parameter is different from the plurality of values. According to the embodiment of the application, when the current oral cavity cleaning position of the brush head is the first position, the control motor drives the brush head to swing by the variable parameters with a plurality of values changing back and forth, and when the current oral cavity cleaning position of the brush head is the second position adjacent to the first position, the control motor drives the brush head to swing by the fixed parameters which are different from the plurality of values, so that an omnibearing changing swing mode is formed, and the illusion that the first position and the second position are the same due to the fact that the fixed parameters are the same as the variable parameters is avoided.

In some possible embodiments, the first location may be a lateral flank and the second location may be an occlusal flank. The lateral sides include an inner side and an outer side. Because the gingival sulcus exists on the inner tooth surface and the outer tooth surface, dirt can be more easily hidden, the first parameter can be set to be a variable parameter, the motor is controlled to drive the swing amplitude of the brush head bristle to change, dirt on the side tooth surface is more effectively shoveled away through the changed swing amplitude, and the oral cavity cleaning effect of the side tooth surface is improved. In order to achieve the effect of reminding the user that the current oral cavity cleaning position is changed, the second parameter can be set to be a fixed parameter different from the first parameter, and the motor is controlled to drive the brush head to swing in a fixed swing mode by the fixed parameter, so that the swing mode of the brush head in the second position can be changed more obviously than the swing mode in the first position.

Further, the first parameter includes a fourth frequency and a fourth duty cycle, and the second parameter includes a fifth frequency and a fifth duty cycle. In order to ensure that the tooth brushing modes corresponding to different oral cavity cleaning positions are different, the fourth frequency is changed in the second frequency range, the fourth duty ratio is changed in the second duty ratio range, the fifth frequency is smaller than or equal to the minimum value of the second frequency range, and the fifth duty ratio is larger than or equal to the maximum value of the second duty ratio range, so that the brush head is driven by the motor to generate obvious change swing modes through different parameters, and the effect of reminding a user that the current oral cavity cleaning position has changed is further realized.

Illustratively, the second frequency may be in a range of 260Hz to 285Hz, the second duty cycle may be in a range of 65% -85%, the fifth frequency may be in a range of 260Hz, and the fifth duty cycle may be in a range of 85%.

Further, the minimum value of the second frequency range is equal to the fifth frequency, and/or the maximum value of the second duty ratio range is equal to the fifth duty ratio, so that not only can the tooth brushing modes between different lateral tooth surfaces and occlusal surfaces be ensured to be obviously different, but also the change of the swinging mode of the brush head between different tooth surfaces can be realized only by changing the duty ratio or the frequency, the reaction time of the electric toothbrush when the oral cleaning position is switched is shortened, and the oral cleaning efficiency is improved.

In some possible embodiments, in order to ensure that the statistics of the time period of the electric toothbrush for cleaning the oral cavity at each oral cavity cleaning position is more accurate, the working time period of the electric toothbrush with the first parameter may be used as the cleaning time period of the electric toothbrush at the first position, and the working time period of the electric toothbrush with the second parameter may be used as the cleaning time period of the electric toothbrush at the second position, so as to avoid the problem that the ineffective cleaning time when the electric toothbrush is at a certain position but does not perform oral cavity cleaning work or does not perform oral cavity cleaning work with the parameter corresponding to the position is miscalculated in the cleaning time period corresponding to the position, so that the cleaning effect of the position is poor.

Referring next to fig. 4, a flowchart of another control method of the electric toothbrush according to an embodiment of the present application is schematically shown. As shown in fig. 4, the control method of the electric toothbrush includes the following steps:

s401, identifying the current oral cleaning position of the brush head.

Specifically, S401 corresponds to S201, and will not be described here.

S402, judging whether the electric toothbrush is changed from the previous oral cleaning position to the current oral cleaning position.

Specifically, after the current oral cleaning position of the brush head is identified, whether the electric toothbrush is changed from the previous oral cleaning position to the current oral cleaning position can be judged first, namely whether the user switches the position of the electric toothbrush for oral cleaning is judged. The previous oral cleaning position is a different oral cleaning position from the current oral cleaning position.

S403, if the electric toothbrush is changed from the previous oral cleaning position to the current oral cleaning position, judging whether the residence time of the current oral cleaning position is longer than the preset time.

Specifically, in order to avoid frequent and meaningless changes of parameters of the motor caused by the fact that the position which is passed through briefly when the electric toothbrush rolls is also identified, after judging that the brush head of the electric toothbrush is converted from the previous oral cleaning position to the current oral cleaning position, whether the residence time of the current oral cleaning position is longer than the preset time can be further judged, and only when the residence time of the brush head is longer than the preset time in the current oral cleaning position, the current oral cleaning position of the brush head is considered to be switched, the motor is controlled to drive the brush head to swing according to the parameters corresponding to the current oral cleaning position. The residence time of the current oral cleaning position is the residence time of the electric toothbrush on a certain tooth surface or a certain tooth area. The preset time period may be, but is not limited to, 1s, 0.5s, etc.

It should be understood that the above-mentioned stay period does not necessarily refer to a period when the electric toothbrush is stationary on a certain tooth surface or a certain tooth area, and may also refer to a period when the electric toothbrush brushes on a certain tooth surface or a certain tooth area, which is not limited in this embodiment of the present application.

Alternatively, the position identifier may include a multi-axis sensor for sensing motion data of the electric toothbrush. The current oral cleaning position residence time can be determined based on the change in the motion data of the electric toothbrush sensed by the multi-axis sensor.

S404, if the electric toothbrush is not changed from the previous oral cleaning position to the current oral cleaning position, or the residence time of the current oral cleaning position is less than or equal to the preset time, controlling the motor to maintain the parameters corresponding to the previous oral cleaning position to drive the brush head to swing.

Specifically, if the electric toothbrush is not changed from the previous oral cleaning position to the current oral cleaning position, for example, but not limited to, the electric toothbrush always performs oral cleaning work at the current oral cleaning position or the electric toothbrush does not perform oral cleaning work before being at the current oral cleaning position, the electric toothbrush can be considered that the oral cleaning position being cleaned is not switched, and then the motor can be controlled to keep the previous oral cleaning position, that is, parameters corresponding to the current oral cleaning position which is not switched, to drive the brush head to swing.

Specifically, if the electric toothbrush is changed from the previous oral cleaning position to the current oral cleaning position, but the residence time of the current oral cleaning position of the electric toothbrush is less than or equal to the preset time, the current oral position can be considered to be the position which is passed by the electric toothbrush briefly when the electric toothbrush rolls over, so as to avoid frequent and meaningless changes of parameters of the motor under the condition, the motor can be controlled to maintain the parameters corresponding to the previous oral cleaning position to drive the brush head to swing.

S405, if the stay time of the current oral cavity cleaning position is longer than the preset time and the current oral cavity cleaning position is the first position, controlling the motor to drive the brush head to swing according to the first parameter.

Specifically, the stay time period of the current oral cleaning position is longer than the preset time period may include: the residence time of the electric toothbrush on a certain tooth surface is longer than a preset time period, and/or the residence time of the electric toothbrush on a certain tooth area is longer than a preset time period.

Alternatively, as shown in fig. 3, the first position may be the lateral flank 370, and the first parameter may be a first certain parameter. The brush head includes outer bristles and middle bristles. The controlling the motor to drive the brush head to swing according to the first parameter may include: the motor is controlled to drive the brush head to swing by a first fixed swing according to a first parameter, when the brush head swings by the first fixed swing, the outer bristles of the brush head brush, and the middle bristles of the brush head slightly shake, and the first fixed swing is determined by the length of teeth, so that more effective oral cavity cleaning operation is realized according to the actual condition of the outer tooth surface, and the accuracy of the swing control of the brush head is improved.

S406, if the stay time of the current oral cavity cleaning position is longer than the preset time and the current oral cavity cleaning position is the second position, controlling the motor to drive the brush head to swing according to the second parameter.

Alternatively, as shown in fig. 3, the second position may be the occlusal surface 380, and the second parameter may be a second fixed parameter. The brush head includes outer bristles and middle bristles. The controlling the motor to drive the brush head to swing according to the second parameter may include: the motor is controlled to drive the brush head to swing with a second fixed swing by a second parameter, and when the brush head swings with the second fixed swing, the vibration intensity of the middle brush hair is larger than that of the outer brush hair. Because the occlusal surface is narrower, is V type cross section, and the nest ditch is irregular, above-mentioned second fixed swing can be less than above-mentioned first fixed swing to through the vibration intensity of reinforcing brush hair mid portion, realize effectively cleaning V type nest ditch, through reducing the swing amplitude simultaneously, more effective laminating narrow occlusal surface still can not harm oral mucosa simultaneously.

S407, if the stay time of the current oral cavity cleaning position is longer than the preset time and the current oral cavity cleaning position is the third position, controlling the motor to drive the brush head to swing according to the third parameter.

Specifically, if the position identifier identifies that the residence time of the current oral cavity cleaning position corresponding to the brush head is longer than the preset time and the current oral cavity cleaning position is the third position, the motor can be directly controlled to drive the brush head to swing according to the third parameter corresponding to the third position. The third parameter is different from the first parameter and the second parameter.

Alternatively, as shown in fig. 3, the third position may be the inner flank 390 and the third parameter may be a variable parameter. Because the inner side tooth surface is deep and long, the inner side tooth surface is difficult to penetrate into, and residues are left in gingival sulcus, the driving of the brush head by the control motor through the third parameter can comprise: the motor is controlled to drive the brush head to swing with a variable swing by a third parameter, and when the brush head swings with the variable swing, the brush hair in the middle is switched back and forth between micro-vibration and sweeping, so that bacterial plaque and soft scale in an inner gingival sulcus are effectively removed by controlling the brush head to swing with the variable swing, and the brush hair swinging area is larger and is easier to penetrate into the inner gingival margin to clean the inner gingival.

In the embodiment of the application, when the user is identified to clean the oral cavity of the outer tooth surface 370, the motor is controlled to drive the brush head to swing in a fixed swinging mode by a first certain parameter; when the user is identified to clean the oral cavity of the occlusal surface 380, the motor is controlled to drive the brush head to swing in another fixed swinging mode by a second fixed parameter different from the first fixed parameter; recognizing that when a user cleans the oral cavity on the inner tooth surface 390, the motor is controlled to drive the brush head to swing in a variable swinging mode, on one hand, according to different tooth surface conditions, the user can compensate the nonstandard oral cavity cleaning posture of the user through the change of the swinging mode of the brush head during oral cavity cleaning, so that the oral cavity cleaning effect of each tooth surface of the user is ensured, and on the other hand, according to the change of different adjacent positions, the change of the swinging mode of the brush head can be distinguished by controlling the motor in different parameter changing conditions (such as changing a first fixed parameter into a second fixed parameter and changing a second fixed parameter into a changed parameter), so that the user can be reminded of the change of the current oral cavity cleaning position more effectively, so that the user can adjust the oral cavity cleaning posture in time, and the oral cavity cleaning effect of the user is improved.

Further, the first constant parameter includes a first frequency and a first duty cycle, the second constant parameter includes a second frequency and a second duty cycle, and the variable parameter includes a third frequency and a third duty cycle. When the first position is the outer tooth surface, the second position is the occlusal surface, and the third position is the inner tooth surface, the occlusal surface is relatively narrow compared with the outer tooth surface, and the V-shaped fossa is irregular, so that the swing amplitude is not required to be large, the first frequency is set to be larger than the second frequency, the first duty ratio is set to be smaller than the second duty ratio, the V-shaped fossa can be effectively cleaned only by setting the vibration intensity of the middle part of the enhanced bristle, and meanwhile, the swing amplitude of the brush head is reduced, so that the bristle can be more effectively attached to the narrow occlusal surface and the effect of not damaging the cavity mucous membrane can be achieved. Since the lingual side (inner side tooth surface) is relatively long and is difficult to penetrate into, and residues are easy to leave in the gingival sulcus, by setting the third frequency to be changed in the first frequency range and the third duty cycle to be changed in the first duty cycle range, the swinging area of the bristles on the brush head is larger, and the bristles are more likely to penetrate into the inner side gingival margin, so that bacterial plaque, soft scale and the like in the inner side gingival sulcus can be effectively removed.

Illustratively, the first frequency may be, but is not limited to being, a value in the range of 265Hz to 290Hz, and the first duty cycle may be, but is not limited to being, a value in the range of 50% -70%. The second frequency may be, but is not limited to, a value in the range of 240Hz to 270Hz, and the second duty cycle may be, but is not limited to, a value in the range of 60% to 80%. The first frequency range may be, but not limited to, a frequency range of 245Hz to 290Hz, and the first duty ratio range may be, but not limited to, a duty ratio range of 50% to 80%.

Alternatively, as shown in fig. 5, the third frequency may be, but not limited to, reciprocally changed in a first frequency range according to a trend of changing to be larger and then smaller, and the third duty may be, but not limited to, reciprocally changed in a first duty range according to a trend of changing to be smaller and then larger, that is, when the third frequency is larger in the first frequency range, the third duty is smaller in the first duty range, and when the third frequency is smaller in the first frequency range, the third duty is larger in the first duty range, so that the bristles of the brush head are driven to be gently swept by the micro-fibrillation by controlling the motor with the third frequency and the third duty which are changed in the trend, so that the bristles can penetrate into the inner gingival margin, and the oral cleaning effect of the inner tooth surface is further improved.

Alternatively, in order to ensure that the bristles on the brush head can achieve a horizontal brushing or vibrating effect based on different swinging modes of the brush head, the swinging direction of the brush head can be set to swing back and forth around the extending direction of the brush head as an axis.
