Description

Technical Field

[0001] This application relates to the technical field of oral care, and particularly to an electric toothbrush. Background Art

[0002] In related technologies, an electric toothbrush usually has several modes. The electric toothbrush can switch different modes by changing parameters such as the vibration frequency and amplitude of the motor, so as to achieve different care effects, such as cleaning, massaging, and caring. However, since the movement direction of the motor is relatively single, it is difficult for the electric toothbrush to achieve diversified care effects well and cannot meet the user's needs. Summary of the Utility Model

[0003] An embodiment of this application provides an electric toothbrush, which can solve the problem that it is difficult for an electric toothbrush to achieve diversified care effects well.

[0004] An embodiment of this application provides an electric toothbrush, which has a first mode and a second mode. The electric toothbrush includes an electric toothbrush head, a motor, and a circuit board connected to the motor. The motor includes a first magnetic mechanism and a second magnetic mechanism. In the first mode, the circuit board provides a first electrical signal to the motor to enable the first magnetic mechanism to drive the electric toothbrush head to perform a first movement, and the circuit board provides a second electrical signal to the motor to enable the second magnetic mechanism to drive the electric toothbrush head to perform a second movement; in the second mode, the circuit board provides the first electrical signal to the motor to enable the first magnetic mechanism to drive the electric toothbrush head to perform the first movement; or, the circuit board provides the second electrical signal to the motor to enable the second magnetic mechanism to drive the electric toothbrush head to perform the second movement, and the movement directions of the first movement and the second movement are different.

[0005] In the electric toothbrush according to the embodiment of this application, the circuit board can provide a first electrical signal to the motor to enable the first magnetic mechanism to drive the electric toothbrush head to perform a first movement; the circuit board can provide a second electrical signal to the motor to enable the second magnetic mechanism to drive the electric toothbrush head to perform a second movement, and the movement directions of the first movement and the second movement are different. That is, the motor has two magnetic mechanisms, and the two magnetic mechanisms can output movements in different directions respectively. Moreover, in the first mode, the electric toothbrush head performs the first movement and the second movement; in the second mode, the electric toothbrush head performs the first movement or the second movement. That is, the electric toothbrush head can perform movements in different directions according to different operation modes of the electric toothbrush. In this way, the electric toothbrush can combine more care modes, which is conducive to achieving diversified care effects of the electric toothbrush and effectively meeting the user's needs.

[0006] In some embodiments, in the first mode, the first magnetic mechanism and the second magnetic mechanism move synchronously to drive the electric toothbrush head to perform a combined movement of the first movement and the second movement.

[0007] Among them, the circuit board can output a first electrical signal and a second electrical signal to the motor simultaneously, so that the first magnetic mechanism and the second magnetic mechanism move synchronously, thereby driving the electric toothbrush head to synchronously perform a combined movement of the first movement and the second movement. This combined movement can be an arc (smooth curve) movement, thereby achieving a full range of scraping of the teeth and improving the cleaning effect. In addition, since the combined movement is an arc movement, in this way, during the process of the electric toothbrush head cleaning the teeth, it can smoothly scrape the tooth surface or the position where the tooth meets the gum, thereby reducing the possibility of damaging the gum and improving the oral protection effect.

[0008] In some embodiments, in the first mode, the first magnetic mechanism and the second magnetic mechanism move alternately to drive the electric toothbrush head to perform a combined movement of the first movement and the second movement.

[0009] Exemplarily, the circuit board can output the first electrical signal alone, so that the first magnetic mechanism drives the electric toothbrush head to perform the first movement (reciprocating rotation) for a period of time, and then output the second electrical signal, so that the second magnetic mechanism drives the electric toothbrush head to perform the second movement (reciprocating movement). In this way, the electric toothbrush head can loosen the dental calculus on the teeth when performing the first movement, and when the electric toothbrush head performs the second movement, the electric toothbrush head can peel off the loosened dental calculus, thereby ensuring the cleaning effect of the electric toothbrush head.

[0010] In some embodiments, in the second mode, the first magnetic mechanism or the second magnetic mechanism moves to drive the electric toothbrush head to perform a unidirectional movement of the first movement or the second movement.

[0011] In some embodiments, the first magnetic mechanism and the second magnetic mechanism drive the electric toothbrush head to perform a combined movement, and the first magnetic mechanism or the second magnetic mechanism drives the electric toothbrush head to perform a unidirectional movement; the electric toothbrush further has a third mode, in which the first magnetic mechanism and the second magnetic mechanism drive the electric toothbrush head to alternately perform the combined movement and the unidirectional movement.

[0012] Thus, compared with an electric toothbrush head that only performs a combined motion or a unidirectional motion, the electric toothbrush head alternately performs a combined motion and a unidirectional motion. On the one hand, it enables the electric toothbrush head to alternately output vibrations with at least two different trajectories, that is, enables the electric toothbrush head to perform more complex motion trajectories, so that the electric toothbrush head can scrape the teeth in more directions, and thus effectively remove dental plaque or tartar. On the other hand, it can increase the change in the motion direction of the electric toothbrush head, so that the bristles of the electric toothbrush head can better penetrate into the interdental spaces or the occlusal surface pits and fissures, which is conducive to improving the cleaning effect of the electric toothbrush.

[0013] In some embodiments, the first motion includes a reciprocating rotation about the longitudinal direction of the electric toothbrush head; the second motion includes a reciprocating movement along the longitudinal direction of the electric toothbrush head.

[0014] Wherein, the motion trajectories of the first motion and the second motion are perpendicular to each other. In this way, when the electric toothbrush head performs the first motion and the second motion, the electric toothbrush head can better loosen the tartar and improve the cleaning effect. In addition, the reciprocating linear motion can replace the horizontal motion when the user manually uses the electric toothbrush, and combined with the reciprocating rotation motion of the electric toothbrush head, the electric toothbrush head can help the user perform oral cleaning through mechanical motion, avoiding the influence of individual operation differences of the user on the oral cleaning effect. And this motion mode fits the motion mode of the electric toothbrush head corresponding to the Bass brushing method. Thus, by controlling the motion mode of the electric toothbrush head, the user can directly master the Bass brushing method.

[0015] In some embodiments, the maximum output power of the first magnetic mechanism is greater than the maximum output power of the second magnetic mechanism.

[0016] Specifically, when the first magnetic mechanism drives the electric toothbrush head to perform the first motion, the electric toothbrush head can loosen the tartar; when the second magnetic mechanism drives the electric toothbrush head to perform the second motion, the electric toothbrush head can increase the loosening range of the electric toothbrush head, so that the cleaning range can be increased while the scraping direction is superimposed, and thus the loosened tartar can be effectively peeled off. Therefore, the maximum output power of the first magnetic mechanism being greater than the maximum output power of the second magnetic mechanism can improve the cleaning effect of the electric toothbrush. And compared with the case where the maximum output power of the first magnetic mechanism is equal to the maximum output power of the second magnetic mechanism, the size of the second magnetic mechanism in this embodiment is smaller, so that the space occupied by the motor can be reduced, which is beneficial to the miniaturization of the electric toothbrush.

[0017] In some embodiments, the first magnetic mechanism is closer to the electric toothbrush head than the second magnetic mechanism. Thus, compared with the case where the first magnetic mechanism is farther from the electric toothbrush head than the second magnetic mechanism, the length of the first mover shaft is shorter, thereby reducing the loss of the power output by the first magnetic mechanism during transmission and ensuring the stability of the power output of the first magnetic mechanism.

[0018] In some embodiments, the first magnetic mechanism includes a first mover shaft, the second magnetic mechanism includes a second mover shaft, and the first mover shaft and the second mover shaft are integrally formed to form the output shaft of the motor. The first magnetic mechanism is connected to the electric toothbrush head through the output shaft and drives the output shaft to move to drive the electric toothbrush head to perform the first movement. The second magnetic mechanism is connected to the electric toothbrush head through the output shaft and drives the output shaft to move to drive the electric toothbrush head to perform the second movement.

[0019] Wherein, the first mover shaft and the second mover shaft are integrally formed to form the output shaft of the motor, that is, the first mover shaft and the second mover shaft are integrally formed to form a whole (i.e., the output shaft of the motor). Thereby, the connection strength between the first mover shaft and the second mover shaft can be improved, preventing the first mover shaft and the second mover shaft from disconnecting during the process of the motor driving the electric toothbrush head to move, and thus ensuring the stability and reliability of the operation of the electric toothbrush.

[0020] In some embodiments, the motor further includes a reset mechanism, and the reset mechanism cooperates with the first mover shaft and / or the second mover shaft. The reset mechanism is used to reset the first mover shaft to the zero-axis position in the moving direction of the first movement, and to reset the second mover shaft to the zero-axis position in the moving direction of the second movement.

[0021] Compared with not resetting the motor before mode switching, the setting of the reset mechanism can make the circuit board control the movement track of the electric toothbrush head more accurately, thereby better meeting the user's oral cleaning needs. It should be noted that the mode switching of the electric toothbrush may include: the electric toothbrush switches from the first mode to the second mode; or, the electric toothbrush switches from the second mode to the first mode.

[0022] In some embodiments, the electric toothbrush has multiple gears in the first mode, and in different gears, the operating parameters of the first magnetic mechanism and the operating parameters of the second magnetic mechanism are respectively adjustable. The electric toothbrush has multiple gears in the second mode, and in different gears, the operating parameters of the first magnetic mechanism or the operating parameters of the second magnetic mechanism are adjustable.

[0023] Among them, since the operating parameters of the magnetic mechanism (including the first magnetic mechanism and the second magnetic mechanism) are adjustable in different gears, the electric toothbrush head can have different movement trajectories in different gears. In this way, the circuit board can adjust different gears to enable the electric toothbrush head to combine various nursing effects, adapt to the oral conditions and cleaning habits of different users, effectively meet the user's usage requirements, and improve the nursing effect of the electric toothbrush.

[0024] In some embodiments, in the first mode, the frequency of the first magnetic mechanism is greater than the frequency of the second magnetic mechanism. Thus, when the circuit board outputs a first electrical signal to the motor and outputs a second electrical signal to the motor, the motor can drive the electric toothbrush head to execute a movement trajectory similar to a sine curve or a movement trajectory similar to a spring shape. In this way, it can simulate the brushing method of moving and shaking up and down when the user uses the electric toothbrush, thereby improving the cleaning effect of the electric toothbrush on dental plaque. Moreover, when the electric toothbrush head can execute a movement trajectory similar to a sine curve or a movement trajectory similar to a spring shape, the electric toothbrush head can smoothly scrape the tooth surface or the position where the tooth meets the gum, thereby reducing the possibility of damaging the gum and improving the oral protection effect.

[0025] In some embodiments, the frequency of the first magnetic mechanism is more than twice the frequency of the second magnetic mechanism.

[0026] In some embodiments, the operating parameters of the first magnetic mechanism in the first mode are less than the operating parameters of the first magnetic mechanism in the second mode. The operating parameters of the second magnetic mechanism in the first mode are less than the operating parameters of the second magnetic mechanism in the second mode. Thus, the power output by the motor in the first mode is less than the power output by the motor in the second mode. This can not only remind the user that the electric toothbrush is in the on state through the relatively slight vibration of the electric toothbrush head, but also prevent the problem of toothpaste splashing caused by the electric toothbrush being turned on when the electric toothbrush head is not in the mouth (for example, when the user is applying toothpaste), improving the user experience.

[0027] In some embodiments, the operating parameters of the first magnetic mechanism in one gear are different from at least some of the operating parameters of the first magnetic mechanism in another gear; and / or the operating parameters of the second magnetic mechanism in one gear are different from at least some of the operating parameters of the second magnetic mechanism in another gear. This can enable the electric toothbrush head to have different movement trajectories in different gears, so that the circuit board 30 can adjust different gears to enable the electric toothbrush head to combine various nursing effects, adapt to the oral conditions and cleaning habits of different users, effectively meet the user's usage requirements, and improve the nursing effect of the electric toothbrush.

[0028] In some embodiments, in the first mode, at least some of the operating parameters of the first magnetic mechanism increase or decrease when the gear is increased; and / or, at least some of the operating parameters of the second magnetic mechanism increase or decrease when the gear is increased. In the second mode, at least some of the operating parameters of the first magnetic mechanism increase or decrease when the gear is increased; or, at least some of the operating parameters of the second magnetic mechanism increase or decrease when the gear is increased.

[0029] Specifically, in some embodiments, in the first mode, at least some of the operating parameters of the first magnetic mechanism increase when the gear is increased; and / or, at least some of the operating parameters of the second magnetic mechanism increase when the gear is increased, whereby the electric toothbrush can output a stronger cleaning effect and improve the cleaning effect of the electric toothbrush. In other embodiments, in the first mode, at least some of the operating parameters of the first magnetic mechanism decrease when the gear is increased; and / or, at least some of the operating parameters of the second magnetic mechanism decrease when the gear is increased, whereby the cleaning effect output by the electric toothbrush can be reduced and the protection effect of the electric toothbrush can be improved.

[0030] In some embodiments, in the second mode, at least some of the operating parameters of the first magnetic mechanism increase when the gear is increased; or, at least some of the operating parameters of the second magnetic mechanism increase when the gear is increased, whereby the electric toothbrush can output a stronger cleaning effect and improve the cleaning effect of the electric toothbrush. In other embodiments, in the second mode, at least some of the operating parameters of the first magnetic mechanism decrease when the gear is increased; or, at least some of the operating parameters of the second magnetic mechanism decrease when the gear is increased, whereby the cleaning effect output by the electric toothbrush can be reduced and the protection effect of the electric toothbrush can be improved.

[0031] In some embodiments, the motor further includes a detection mechanism for detecting the operating parameters of the first magnetic mechanism; or, the detection mechanism is for detecting the operating parameters of the second magnetic mechanism.

[0032] Wherein, when the detection mechanism is used to detect the operating parameters of the first magnetic mechanism and the electric toothbrush head performs a unidirectional movement, the circuit board outputs a first electrical signal to the first magnetic mechanism so that the first magnetic mechanism drives the electric toothbrush head to perform a first movement; when the detection mechanism is used to detect the operating parameters of the second magnetic mechanism and the electric toothbrush head performs a unidirectional movement, the circuit board outputs a second electrical signal to the second magnetic mechanism so that the second magnetic mechanism drives the electric toothbrush head to perform a second movement, that is, when the electric toothbrush head performs a unidirectional movement, the magnetic mechanism with a detection function outputs power, so that the power output by the magnetic mechanism can be controlled more precisely.

[0033] In some embodiments, the motor further includes a housing; when the operating parameters include frequency or amplitude, the detection mechanism includes a first detection member and a second detection member, and one of the first detection member and the second detection member is disposed on the housing. The other of the first detection member and the second detection member is disposed on the first magnetic mechanism, and the first detection member and the second detection member cooperate to detect the operating parameters of the first magnetic mechanism; or, the other of the first detection member and the second detection member is disposed on the second magnetic mechanism, and the first detection member and the second detection member cooperate to detect the operating parameters of the second magnetic mechanism.

[0034] In some embodiments, when the operating parameter includes frequency, the detection mechanism includes an angle sensor. When the operating parameter includes amplitude, the detection mechanism includes a magnetic sensor, and the magnetic sensor is used to detect an angle or a displacement length.

The same or similar reference numerals in the drawings denote the same or similar elements or elements having the same or similar functions throughout. Additionally, the embodiments of the present application described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application and should not be construed as a limitation to the present application.

[0048] In the related art, an electric toothbrush usually has several modes. The electric toothbrush can switch different modes by changing parameters such as the vibration frequency and amplitude of the motor, so as to achieve different care effects, such as cleaning, massaging, and caring. However, since the movement direction of the motor is relatively single, this will cause the electric toothbrush to be unable to achieve diversified care effects and is difficult to meet the usage needs of users. To solve this problem, the embodiments of the present application provide an electric toothbrush 100( Figure 1 as shown).

[0049] Please refer to Figure 1 and Figure 2 , the embodiments of the present application provide an electric toothbrush 100. The electric toothbrush 100 has a first mode and a second mode. The electric toothbrush 100 includes an electric toothbrush head 10, a motor 20, and a circuit board 30. The motor 20 includes a first magnetic mechanism 21 and a second magnetic mechanism 23. The circuit board 30 is connected to the motor 20. In the first mode, the circuit board 30 provides a first electrical signal to the motor 20 to cause the first magnetic mechanism 21 to drive the electric toothbrush head 10 to perform a first movement, and the circuit board 30 provides a second electrical signal to the motor 20 to cause the second magnetic mechanism 23 to drive the electric toothbrush head 10 to perform a second movement; in the second mode, the circuit board 30 provides a first electrical signal to the motor 20 to cause the first magnetic mechanism 21 to drive the electric toothbrush head 10 to perform a first movement; or, the circuit board 30 provides a second electrical signal to the motor 20 to cause the second magnetic mechanism 23 to drive the electric toothbrush head 10 to perform a second movement, and the movement directions of the first movement and the second movement are different.

[0050] Among them, when the electric toothbrush head 10 performs the first movement and / or the second movement, the electric toothbrush head 10 can clean the part to be cleaned in the oral cavity. In some embodiments of the present application, the first magnetic mechanism 21 includes a first mover shaft 211, and the second magnetic mechanism 23 includes a second mover shaft 231. The first mover shaft 211 and the second mover shaft 231 are integrally formed to form the output shaft 201 of the motor 20. The first magnetic mechanism 21 is connected to the electric toothbrush head 10 through the output shaft 201, and drives the output shaft 201 to move to drive the electric toothbrush head 10 to perform the first movement. The second magnetic mechanism 23 is connected to the electric toothbrush head 10 through the output shaft 201, and drives the output shaft 201 to move to drive the electric toothbrush head 10 to perform the second movement.

[0051] Specifically, when the circuit board 30 provides a first electrical signal to the motor 20, the first magnetic mechanism 21 can drive the output shaft 201 to move to drive the electric toothbrush head 10 to perform the first movement; when the circuit board 30 provides a second electrical signal to the motor 20, the first magnetic mechanism 21 can drive the output shaft 201 to move to drive the electric toothbrush head 10 to perform the second movement, so that the electric toothbrush head 10 decomposes the toothpaste into fine foam to clean the part to be cleaned in the oral cavity. It should be noted that in some embodiments, the part to be cleaned may include but is not limited to the tooth surface, tooth tip, tooth root, and occlusal surface grooves of the teeth.

[0052] Among them, please combine Figure 3 , the first mover shaft 211 and the second mover shaft 231 are integrally formed to form the output shaft 201 of the motor 20, that is, the first mover shaft 211 and the second mover shaft 231 are integrally formed to form a whole (that is, the output shaft 201 of the motor 20). Thereby, the connection strength between the first mover shaft 211 and the second mover shaft 231 can be improved, and the disconnection of the first mover shaft 211 and the second mover shaft 231 can be prevented during the process of the motor 20 driving the electric toothbrush head 10 to move, so as to ensure the stability and reliability of the operation of the electric toothbrush 100. It should be noted that in some embodiments, the electric toothbrush head 10 and the output shaft 201 can be connected in a detachable connection manner. On the one hand, this can facilitate the replacement of different models or different materials of electric toothbrush heads 10; on the other hand, when the service life of the electric toothbrush head 10 is long enough to cause the cleaning effect to decline, it is convenient to replace a new electric toothbrush head 10, so as to ensure the cleaning effect of the electric toothbrush 100.

[0053] It can be understood that, in other embodiments, the first mover shaft 211 and the second mover shaft 231 can be a split structure, and a detachable connection method or a non-detachable connection method can be adopted between the first mover shaft 211 and the second mover shaft 231 to form an integral body to form the output shaft 201. Among them, the detachable connection methods include but are not limited to snap connection or bolt connection, etc.; the non-detachable connection methods include but are not limited to bonding or welding, etc.

[0054] A processor can be electrically connected to the circuit board 30, and the processor can be a micro control unit (MCU), etc. Among them, the circuit board 30 includes but is not limited to a rigid printed circuit board (PCB) or a flexible printed circuit (FPC), etc. In some embodiments of the present application, the circuit board 30 can provide a first electrical signal to the motor 20, and the first magnetic mechanism 21 can drive the electric toothbrush head 10 to perform a first movement based on the first electrical signal; the circuit board 30 can provide a second electrical signal to the motor 20, and the second magnetic mechanism 23 can drive the electric toothbrush head 10 to perform a second movement based on the second electrical signal.

[0055] Among them, in the first mode, the circuit board 30 provides a first electrical signal to the motor 20 to enable the first magnetic mechanism 21 to drive the electric toothbrush head 10 to perform a first movement, and the circuit board 30 provides a second electrical signal to the motor 20 to enable the second magnetic mechanism 23 to drive the electric toothbrush head 10 to perform a second movement. That is, in the first mode, both the first magnetic mechanism 21 and the second magnetic mechanism 23 participate in driving the electric toothbrush head 10 to move. Thus, the electric toothbrush head 10 can output a variety of different movement trajectories. That is, the electric toothbrush head 10 can move along a variety of different movement directions or different movement synthesis directions, so as to realize multi-directional scraping of teeth, and further enable the electric toothbrush 100 to achieve diversified care effects and meet the user's usage requirements;

[0056] In the second mode, the circuit board 30 provides a first electrical signal to the motor 20 to enable the first magnetic mechanism 21 to drive the electric toothbrush head 10 to perform a first movement; or, the circuit board 30 provides a second electrical signal to the motor 20 to enable the second magnetic mechanism 23 to drive the electric toothbrush head 10 to perform a second movement. That is, in the second mode, one of the first magnetic mechanism 21 and the second magnetic mechanism 23 participates in driving the electric toothbrush head 10 to move. Thus, the electric toothbrush head 10 can output a specific movement trajectory, so as to specifically meet the user's usage requirements.

[0057] Please combine Figure 4 and Figure 5, in some embodiments, the first movement includes a reciprocating rotation about the longitudinal direction X of the electric toothbrush head 10 ( Figure 4 as shown); the second movement includes a reciprocating movement along the longitudinal direction X of the electric toothbrush head 10 ( Figure 5 as shown).

[0058] Exemplarily, the circuit board 30 can output a first electrical signal to the motor 20, so that the first magnetic mechanism 21 drives the output shaft 201 to move based on the first electrical signal to drive the electric toothbrush head 10 to perform the first movement, that is, to drive the electric toothbrush head 10 to perform a reciprocating rotation about the longitudinal direction X of the electric toothbrush head 10, so that the electric toothbrush head 10 can scrape the teeth along the first direction to clean dental calculus or dental plaque on the tooth surface, etc. Among them, the first direction is the movement direction of the first movement. The first direction can be the direction from the tooth root to the tooth tip of the tooth; or, the first direction can be the direction from the tooth tip to the tooth root of the tooth.

[0059] The circuit board 30 can output a second electrical signal to the second magnetic mechanism 23, so that the second magnetic mechanism 23 drives the output shaft 201 to move based on the second electrical signal to drive the electric toothbrush head 10 to perform the second movement, that is, to drive the electric toothbrush head 10 to perform a reciprocating movement along the longitudinal direction X of the electric toothbrush head 10, so that the electric toothbrush head 10 can scrape the teeth along the second direction to clean dental calculus or dental plaque on the tooth surface, etc. Among them, the second direction is the movement direction of the second movement. The second direction can be a direction perpendicular to the direction from the tooth root to the tooth tip of the tooth.

[0060] In summary, the movement trajectories of the first movement and the second movement are perpendicular to each other. In this way, when the electric toothbrush head 10 performs the first movement and the second movement, the electric toothbrush head 10 can better loosen dental calculus and improve the cleaning effect. In addition, the reciprocating linear movement can replace the horizontal movement when the user manually uses the electric toothbrush 100, and combined with the reciprocating rotation movement of the electric toothbrush head 10, the electric toothbrush head 10 can help the user perform oral cleaning through mechanical movement, avoiding the influence of individual operation differences of the user on the oral cleaning effect. And this movement mode fits the movement mode of the electric toothbrush head 10 corresponding to the Bass brushing method. In this way, by controlling the movement mode of the electric toothbrush head 10, the user can directly master the Bass brushing method.

[0061] In the electric toothbrush 100 according to the embodiments of the present application, the circuit board 30 can provide a first electrical signal to the motor 20 to enable the first magnetic mechanism 21 to drive the electric toothbrush head 10 to perform a first movement; the circuit board 30 can provide a second electrical signal to the motor 20 to enable the second magnetic mechanism 23 to drive the electric toothbrush head 10 to perform a second movement, and the movement directions of the first movement and the second movement are different. That is, the motor 20 has two magnetic mechanisms, and the two magnetic mechanisms can output movements in different directions respectively. Moreover, in the first mode, the electric toothbrush head 10 performs the first movement and the second movement; in the second mode, the electric toothbrush head 10 performs the first movement or the second movement. That is, the electric toothbrush head 10 can perform movements in different directions according to different operating modes of the electric toothbrush 100. In this way, the electric toothbrush 100 can combine more care modes, which is beneficial to achieving diversified care effects of the electric toothbrush 100 and effectively meeting the user's usage requirements.

[0062] The electric toothbrush 100 will be further explained below with reference to the accompanying drawings.

[0063] Please refer to Figure 2 and Figure 6 , in some embodiments, the first magnetic mechanism 21 and the second magnetic mechanism 23 move synchronously to drive the electric toothbrush head 10 to perform a combined movement of the first movement and the second movement.

[0064] Specifically, please combine Figure 4 and Figure 5 , in certain embodiments, the circuit board 30 can output the first electrical signal and the second electrical signal to the motor 20 at the same time to enable the first magnetic mechanism 21 and the second magnetic mechanism 23 to move synchronously, so as to drive the electric toothbrush head 10 to synchronously perform a combined movement of the first movement and the second movement. The combined movement can be an arc (smooth curve) movement, thereby realizing all-round scraping of teeth and improving the cleaning effect. In addition, since the combined movement is an arc movement, in this way, during the process of the electric toothbrush head 10 cleaning the teeth, the tooth surface or the position where the tooth is in contact with the gum can be smoothly scraped, thereby reducing the possibility of damaging the gum and improving the oral protection effect.

[0065] In some embodiments, the first magnetic mechanism 21 and the second magnetic mechanism 23 move alternately to drive the electric toothbrush head 10 to perform a combined movement of the first movement and the second movement.

[0066] Specifically, in some embodiments, the circuit board 30 can alternately output a first electrical signal and a second electrical signal, so that the first magnetic force mechanism 21 and the second magnetic force mechanism 23 move alternately, thereby driving the electric toothbrush head 10 to alternately execute a combined motion of a first motion and a second motion. For example, the circuit board 30 can separately output the first electrical signal, and after the first electrical signal ends, separately output the second electrical signal. Exemplarily, the circuit board 30 can separately output the first electrical signal, so that the first magnetic force mechanism 21 drives the electric toothbrush head 10 to execute the first motion (reciprocating rotation) for a period of time, and then output the second electrical signal, so that the second magnetic force mechanism 23 drives the electric toothbrush head 10 to execute the second motion (reciprocating movement). In this way, the dental calculus on the teeth can be loosened when the electric toothbrush head 10 executes the first motion, and when the electric toothbrush head 10 executes the second motion, the loosened dental calculus can be peeled off by the electric toothbrush head 10, thereby ensuring the cleaning effect of the electric toothbrush head 10.

[0067] In some embodiments, the first magnetic force mechanism 21 or the second magnetic force mechanism 23 moves to drive the electric toothbrush head 10 to execute a unidirectional motion of the first motion or the second motion.

[0068] Specifically, the circuit board 30 can separately output the first electrical signal to the first magnetic force mechanism 21, so that the first magnetic force mechanism 21 drives the electric toothbrush head 10 to execute the first motion; or, the circuit board 30 can separately output the second electrical signal to the second magnetic force mechanism 23, so that the second magnetic force mechanism 23 drives the electric toothbrush head 10 to execute the second motion.

[0069] In summary, in the first mode, the electric toothbrush head 10 can synchronously execute the combined motion of the first motion and the second motion, that is, in the first mode, the first magnetic force mechanism 21 and the second magnetic force mechanism 23 move synchronously to drive the electric toothbrush head 10 to execute the combined motion of the first motion and the second motion; or, the electric toothbrush head 10 can alternately execute the combined motion of the first motion and the second motion, that is, in the first mode, the first magnetic force mechanism 21 and the second magnetic force mechanism 23 move alternately to drive the electric toothbrush head 10 to execute the combined motion of the first motion and the second motion.

[0070] In the second mode, the electric toothbrush head 10 can separately execute the unidirectional motion of the first motion; or, the electric toothbrush head 10 can separately execute the unidirectional motion of the second motion. That is, in the second mode, the first magnetic force mechanism 21 or the second magnetic force mechanism 23 moves to drive the electric toothbrush head 10 to execute the unidirectional motion of the first motion or the second motion.

[0071] Please refer to Figure 2 and Figure 6, in some embodiments, the first magnetic mechanism 21 and the second magnetic mechanism 23 drive the electric toothbrush head 10 to perform a combined motion, and the first magnetic mechanism 21 or the second magnetic mechanism 23 drives the electric toothbrush head 10 to perform a unidirectional motion; the electric toothbrush 100 further has a third mode, in which the first magnetic mechanism 21 and the second magnetic mechanism 23 drive the electric toothbrush head 10 to alternately perform a combined motion and a unidirectional motion.

[0072] Thus, compared with the electric toothbrush head 10 only performing a combined motion or a unidirectional motion, the electric toothbrush head 10 alternately performs a combined motion and a unidirectional motion. On the one hand, it can enable the electric toothbrush head 10 to alternately output vibrations with at least two different trajectories, that is, enable the electric toothbrush head 10 to perform a more complex motion trajectory, so that the electric toothbrush head 10 can scrape the teeth in more directions, and thus effectively remove dental plaque or tartar; on the other hand, it can increase the change of the motion direction of the electric toothbrush head 10, so that the bristles of the electric toothbrush head 10 can better extend into the interdental space or the occlusal surface grooves, which is beneficial to improving the cleaning effect of the electric toothbrush 100. In addition, since different users have different oral conditions and brushing habits, alternately performing a combined motion and a unidirectional motion can also better meet the usage needs of users. For example, for users with sensitive teeth, the discomfort during brushing can be reduced by adjusting the ratio of the combined motion and the unidirectional motion.

[0073] Exemplarily, the circuit board 30 can separately output a first electrical signal to the first magnetic mechanism 21 to enable the first magnetic mechanism 21 to drive the electric toothbrush head 10 to perform a unidirectional motion of the first motion, and after the first electrical signal ends, output the first electrical signal and the second electrical signal simultaneously to enable the first magnetic mechanism 21 and the second magnetic mechanism 23 to move synchronously, thereby driving the electric toothbrush head 10 to perform a combined motion of the first motion and the second motion; or, the circuit board 30 can separately output a second electrical signal to the first magnetic mechanism 21 to enable the second magnetic mechanism 23 to drive the electric toothbrush head 10 to perform a unidirectional motion of the second motion, and after the second electrical signal ends, output the first electrical signal and the second electrical signal simultaneously to enable the first magnetic mechanism 21 and the second magnetic mechanism 23 to move synchronously, thereby driving the electric toothbrush head 10 to perform a combined motion of the first motion and the second motion.

[0074] Exemplarily, the circuit board 30 can separately output a first electrical signal to the first magnetic mechanism 21 to cause the first magnetic mechanism 21 to drive the electric toothbrush head 10 to perform a one-way movement of the first movement, and after the first electrical signal ends, alternately output the first electrical signal and the second electrical signal to cause the first magnetic mechanism 21 and the second magnetic mechanism 23 to move alternately, thereby driving the electric toothbrush head 10 to alternately perform a combined movement of the first movement and the second movement; or, the circuit board 30 can separately output a second electrical signal to the first magnetic mechanism 21 to cause the second magnetic mechanism 23 to drive the electric toothbrush head 10 to perform a one-way movement of the second movement, and after the second electrical signal ends, alternately output the first electrical signal and the second electrical signal to cause the first magnetic mechanism 21 and the second magnetic mechanism 23 to move alternately, thereby driving the electric toothbrush head 10 to alternately perform a combined movement of the first movement and the second movement.

[0075] Please refer to Figure 2 , in some embodiments, the maximum output power of the first magnetic mechanism 21 is greater than the maximum output power of the second magnetic mechanism 23.

[0076] Specifically, in some embodiments, when the first magnetic mechanism 21 drives the electric toothbrush head 10 to perform the first movement, the electric toothbrush head 10 can loosen dental calculus; when the second magnetic mechanism 23 drives the electric toothbrush head 10 to perform the second movement, the electric toothbrush head 10 can increase the loosening range of the electric toothbrush head 10, so as to be able to superimpose the scraping direction while increasing the cleaning range, and then effectively peel off the loosened dental calculus. Thus, the maximum output power of the first magnetic mechanism 21 being greater than the maximum output power of the second magnetic mechanism 23 can improve the cleaning effect of the electric toothbrush 100. And, compared with the case where the maximum output power of the first magnetic mechanism 21 is equal to the maximum output power of the second magnetic mechanism 23, the size of the second magnetic mechanism 23 in this embodiment is smaller, so that the space occupied by the motor 20 can be reduced, which is beneficial to the miniaturization of the electric toothbrush 100.

[0077] It can be understood that when the electric toothbrush head 10 performs a separate movement, the circuit board 30 outputs a first electrical signal to the first magnetic mechanism 21 to cause the first magnetic mechanism 21 to drive the electric toothbrush head 10 to perform the first movement. That is, when the electric toothbrush head 10 performs a separate movement, the first magnetic mechanism 21 works, so as to ensure the cleaning effect of the electric toothbrush 100.

[0078] Further, please refer to Figure 3, in some embodiments, the first magnetic mechanism 21 is closer to the electric toothbrush head 10 than the second magnetic mechanism 23. Thus, compared with the case where the first magnetic mechanism 21 is farther from the electric toothbrush head 10 than the second magnetic mechanism 23, the length of the first mover shaft 211 is shorter, thereby reducing the loss of the power output by the first magnetic mechanism 21 during transmission and ensuring the stability of the power output of the first magnetic mechanism 21.

[0079] In some embodiments, the electric toothbrush 100 has multiple gears in the first mode, and in different gears, the operating parameters of the first magnetic mechanism 21 and the operating parameters of the second magnetic mechanism 23 are respectively adjustable. The electric toothbrush 100 has multiple gears in the second mode, and in different gears, the operating parameters of the first magnetic mechanism 21 or the operating parameters of the second magnetic mechanism 23 are adjustable.

[0080] Among them, since the operating parameters of the magnetic mechanism (including the first magnetic mechanism 21 and the second magnetic mechanism 23) are adjustable in different gears, the electric toothbrush head 10 can have different movement trajectories in different gears. Thus, the circuit board 30 can combine a variety of care effects by adjusting different gears to adapt to the oral conditions and cleaning habits of different users, effectively meeting the user's usage requirements and improving the care effect of the electric toothbrush 100.

[0081] It should be noted that in some embodiments, the operating parameters include at least one of frequency and amplitude.

[0082] Specifically, the respective adjustability of the operating parameters of the first magnetic mechanism 21 and the operating parameters of the second magnetic mechanism 23 can be: at least one of the frequency of the first magnetic mechanism 21, the amplitude of the first magnetic mechanism 21, the frequency of the second magnetic mechanism 23, and the amplitude of the second magnetic mechanism 23 is adjustable. That is, in the first mode, the circuit board 30 can adjust at least one of the frequency of the first magnetic mechanism 21, the amplitude of the first magnetic mechanism 21, the frequency of the second magnetic mechanism 23, and the amplitude of the second magnetic mechanism 23 to make the electric toothbrush 100 in different gears.

[0083] The operating parameters of the first magnetic mechanism 21 or the operating parameters of the second magnetic mechanism 23 can be adjustable, which can be: at least one of the frequency of the first magnetic mechanism 21 and the amplitude of the first magnetic mechanism 21 is adjustable; or, at least one of the frequency of the second magnetic mechanism 23 and the amplitude of the second magnetic mechanism 23 is adjustable. That is, when the electric toothbrush 100 is in the second mode and the circuit board 30 provides the first electric signal to the motor 20, the circuit board 30 can adjust at least one of the frequency of the first magnetic mechanism 21 and the amplitude of the first magnetic mechanism 21 to make the electric toothbrush 100 in different gears; or, when the electric toothbrush 100 is in the second mode and the circuit board 30 provides the second electric signal to the motor 20, the circuit board 30 can adjust at least one of the frequency of the second magnetic mechanism 23 and the amplitude of the second magnetic mechanism 23 to make the electric toothbrush 100 in different gears.

[0084] Wherein, the frequency can be the number of reciprocating rotations of the first mover shaft 211 of the first magnetic mechanism 21 per unit time; the amplitude can be the range between the extreme positions of the reciprocating rotation when the first mover shaft 211 performs reciprocating rotation (for example, the range between the first extreme position A11 and the second extreme position A13). Correspondingly, the frequency can be the number of reciprocating linear motions of the second mover shaft 231 of the second magnetic mechanism 23 per unit time; the amplitude can be the range between the extreme positions of the reciprocating linear motion when the second mover shaft 231 performs reciprocating linear motion (for example, the range between the third extreme position A21 and the fourth extreme position A23).

[0085] It should be noted that the first extreme position A11 can be the farthest position that the first mover shaft 211 can reach when the first magnetic mechanism 21 is in motion, and the second extreme position A13 can be the farthest position relative to the first extreme position A11; the third extreme position A21 can be the farthest position that the second mover shaft 231 can reach when the second magnetic mechanism 23 is in motion, and the fourth extreme position A23 can be the farthest position relative to the third extreme position A21.

[0086] Furthermore, in some embodiments, when adjusting the gear, the motion parameters of the first magnetic mechanism 21 gradually increase or gradually decrease; the motion parameters of the second magnetic mechanism 23 gradually increase or gradually decrease. On the one hand, this can prevent the motion trajectory of the electric toothbrush head 10 from changing abruptly, thereby reducing the possibility of toothpaste and foam splashing; on the other hand, it can make the contact between the electric toothbrush head 10 and the teeth have a certain buffer, enabling users to gradually adapt to the brushing force and improving the protection effect.

[0087] Exemplarily, when the electric toothbrush 100 is in the first mode, the circuit board 30 can control the operating parameters of the first magnetic mechanism 21 to continuously increase to the operating parameters of the first magnetic mechanism 21 at the next gear. For example, when the operating data includes frequency, if the frequency of the first magnetic mechanism 21 at one gear is 10HZ and the frequency of the first magnetic mechanism 21 at the next gear is 50HZ, the circuit board 30 can control the first magnetic mechanism 21 to continuously increase from 10HZ to 50HZ at a rate of 5HZ per second. Compared with directly increasing the operating parameters of the first magnetic mechanism 21 to the operating parameters of the first magnetic mechanism 21 at the next gear, the movement trajectory of the first magnetic mechanism 21 driving the electric toothbrush head 10 to perform the first movement in this embodiment will not change abruptly, thereby reducing the possibility of toothpaste and foam splashing.

[0088] In some embodiments, at least some of the operating parameters of the first magnetic mechanism 21 at one gear are different from at least some of the operating parameters of the first magnetic mechanism 21 at another gear; and / or, at least some of the operating parameters of the second magnetic mechanism 23 at one gear are different from at least some of the operating parameters of the second magnetic mechanism 23 at another gear. Thereby, the electric toothbrush head 10 can have different movement trajectories at different gears, so that the circuit board 30 can combine various care effects by adjusting different gears to adapt to the oral conditions and cleaning habits of different users, effectively meeting the user's usage requirements and improving the care effect of the electric toothbrush 100.

[0089] Specifically, in some embodiments, when the operating parameters include frequency and amplitude, the frequency of the first magnetic mechanism 21 at one gear is A and the amplitude is B. The frequency of the first magnetic mechanism 21 at another gear can be A1 (A1 is different from A), and the amplitude is B; or, the frequency of the first magnetic mechanism 21 at another gear can be A1, and the amplitude is B1 (B1 is different from B); or, the frequency of the first magnetic mechanism 21 at another gear can be A, and the amplitude is B1. Similarly, when the operation includes frequency and amplitude, the frequency of the second magnetic mechanism 23 at one gear is C and the amplitude is D, then the frequency of the second magnetic mechanism 23 at another gear can be C1 (C1 is different from C), and the amplitude is D; or, the frequency of the second magnetic mechanism 23 at another gear can be C1, and the amplitude is D1 (D1 is different from D); or, the frequency of the second magnetic mechanism 23 at another gear can be C, and the amplitude is D1.

[0090] In some embodiments, in the first mode, at least some of the operating parameters of the first magnetic mechanism 21 increase or decrease when the gear is raised; and / or, at least some of the operating parameters of the second magnetic mechanism 23 increase or decrease when the gear is raised.

[0091] Specifically, in some embodiments, in the first mode, at least some operating parameters of the first magnetic mechanism 21 increase when the gear is raised; and / or, at least some operating parameters of the second magnetic mechanism 23 increase when the gear is raised, whereby the electric toothbrush 100 can output a stronger cleaning effect and improve the cleaning effect of the electric toothbrush 100.

[0092] In other embodiments, in the first mode, at least some operating parameters of the first magnetic mechanism 21 decrease when the gear is raised; and / or, at least some operating parameters of the second magnetic mechanism 23 decrease when the gear is raised, whereby the cleaning effect output by the electric toothbrush 100 can be reduced and the protection effect of the electric toothbrush 100 can be improved.

[0093] In certain embodiments, in the second mode, at least some operating parameters of the first magnetic mechanism 21 increase or decrease when the gear is raised; or, at least some operating parameters of the second magnetic mechanism 23 increase or decrease when the gear is raised.

[0094] Specifically, in some embodiments, in the second mode, at least some operating parameters of the first magnetic mechanism 21 increase when the gear is raised; or, at least some operating parameters of the second magnetic mechanism 23 increase when the gear is raised, whereby the electric toothbrush 100 can output a stronger cleaning effect and improve the cleaning effect of the electric toothbrush 100.

[0095] In other embodiments, in the second mode, at least some operating parameters of the first magnetic mechanism 21 decrease when the gear is raised; or, at least some operating parameters of the second magnetic mechanism 23 decrease when the gear is raised, whereby the cleaning effect output by the electric toothbrush 100 can be reduced and the protection effect of the electric toothbrush 100 can be improved.

[0096] Please refer to Figure 2 and Figure 6 , in certain embodiments, in the first mode, the frequency of the first magnetic mechanism 21 is greater than the frequency of the second magnetic mechanism 23. Thus, when the circuit board 30 outputs a first electrical signal to the motor 20 and outputs a second electrical signal to the motor 20, the motor 20 can drive the electric toothbrush head 10 to execute a movement trajectory similar to a sine curve or a movement trajectory similar to a spring shape, so that a brushing method of moving and shaking up and down when the user uses the electric toothbrush 100 can be simulated, thereby improving the cleaning effect of the electric toothbrush 100 on dental plaque. And, when the electric toothbrush head 10 can execute a movement trajectory similar to a sine curve or a movement trajectory similar to a spring shape, the electric toothbrush head 10 can smoothly scrape the tooth surface or the position where the tooth meets the gum, thereby reducing the possibility of damaging the gum and improving the oral protection effect.

[0097] It can be understood that in some embodiments, when the electric toothbrush 100 is in the first mode, at all gears of the first mode, the frequency of the first magnetic mechanism 21 is greater than the frequency of the second magnetic mechanism 23. In other embodiments, when the electric toothbrush 100 is in the first mode, at at least one gear of the first mode, the frequency of the first magnetic mechanism 21 is greater than the frequency of the second magnetic mechanism 23.

[0098] Optionally, in some embodiments, the frequency of the first magnetic mechanism 21 is more than twice the frequency of the second magnetic mechanism 23. Exemplarily, when the frequency of the second magnetic mechanism 23 is A, the frequency of the first magnetic mechanism 21 is greater than 2A.

[0099] In some embodiments, the operating parameters of the first magnetic mechanism 21 in the first mode are less than the operating parameters of the first magnetic mechanism 21 in the second mode. The operating parameters of the second magnetic mechanism 23 in the first mode are less than the operating parameters of the second magnetic mechanism 23 in the second mode.

[0100] Specifically, in some embodiments, the circuit board 30 can output different electrical signals to control the switching of the electric toothbrush 100 between the first mode and the second mode. For example, controlling the electric toothbrush 100 to switch from the first mode to the second mode; or, controlling the electric toothbrush 100 to switch from the second mode to the first mode. Moreover, the operating parameters of the first magnetic mechanism 21 in the first mode are less than the operating parameters of the first magnetic mechanism 21 in the second mode, and the operating parameters of the second magnetic mechanism 23 in the first mode are less than the operating parameters of the second magnetic mechanism 23 in the second mode. That is, the power output by the motor 20 in the first mode is less than the power output by the motor 20 in the second mode. Thus, not only can the relatively slight vibration of the electric toothbrush head 10 remind the user that the electric toothbrush 100 is in the on state, but also the problem of toothpaste splashing caused by the electric toothbrush 100 being turned on when the electric toothbrush head 10 is not in the mouth (for example, when the user is applying toothpaste) can be prevented, improving the user experience.

[0101] Please refer to Figures 2 to 5 , in some embodiments, the motor 20 further includes a reset mechanism 27. The reset mechanism 27 cooperates with the first mover shaft 211 and / or the second mover shaft 231. The reset mechanism 27 is used to reset the first mover shaft 211 to the zero-axis position A15 in the moving direction of the first movement, and to reset the second mover shaft 231 to the zero-axis position A25 in the moving direction of the second movement.

[0102] Specifically, in some embodiments, the zero-axis position A15 in the movement direction of the first movement may be located at the first limit position A11, the second limit position A13, or any position between the first limit position A11 and the second limit position A13; the zero-axis position A25 in the movement direction of the second movement may be the third limit position A21, the fourth limit position A23, or any position between the third limit position A21 and the fourth limit position A23. In the embodiments of the present application, only the example where the zero-axis position A15 in the movement direction of the first movement is located at the central position between the first limit position A11 and the second limit position A13, and the zero-axis position A25 in the movement direction of the second movement is located at the central position between the third limit position A21 and the fourth limit position A23 is used for illustration.

[0103] Among them, the reset mechanism 27 resetting the first mover shaft 211 to the zero-axis position A15 in the movement direction of the first movement, and resetting the second mover shaft 231 to the zero-axis position A25 in the movement direction of the second movement may be: the circuit board 30 controls the movement of the reset mechanism 27 to rotate the first mover shaft 211 to the central position between the first limit position A11 and the second limit position A13, and controls the movement of the reset mechanism 27 to move the second mover shaft 231 to the central position between the third limit position A21 and the fourth limit position A23.

[0104] Specifically, in some embodiments of the present application, before the mode switching of the electric toothbrush 100, the circuit board 30 can control the movement of the reset mechanism 27 to reset the first mover shaft 211 to the zero-axis position A15 in the movement direction of the first movement, and reset the second mover shaft 231 to the zero-axis position A25 in the movement direction of the second movement. Thus, compared with not resetting the motor 20 before the mode switching, the setting of the reset mechanism 27 can make the circuit board 30 control the movement trajectory of the electric toothbrush head 10 more accurately, so as to better meet the user's oral cleaning needs. It should be noted that the mode switching of the electric toothbrush 100 may include: the electric toothbrush 100 switching from the first mode to the second mode; or, the electric toothbrush 100 switching from the second mode to the first mode.

[0105] In some embodiments, the reset mechanism 27 includes a first magnetic mechanism 21, and the first magnetic mechanism 21 is energized to drive the first mover shaft 211 to reset to the zero-axis position A15 in the movement direction of the first movement; and / or, the reset mechanism 27 includes a second magnetic mechanism 23, and the second magnetic mechanism 23 is energized to drive the second mover shaft 231 to reset to the zero-axis position A25 in the movement direction of the first movement.

[0106] Specifically, in some embodiments, before the mode switching of the electric toothbrush 100, the circuit board 30 may output a first control signal to the first magnetic mechanism 21 to energize the first magnetic mechanism 21 to drive the first mover shaft 211 to reset to the zero-axis position A15 in the moving direction of the first movement; the circuit board 30 may output a second control signal to the second magnetic mechanism 23 to energize the second magnetic mechanism 23 to drive the second mover shaft 231 to reset to the zero-axis position A25 in the moving direction of the first movement.

[0107] In some embodiments, the reset mechanism 27 includes a first elastic structure connected to the first mover shaft 211 to provide an elastic restoring force to the first mover shaft 211; and / or, the reset mechanism 27 includes a second elastic structure connected to the second mover shaft 231 to provide an elastic restoring force to the second mover shaft 231.

[0108] Specifically, in some embodiments, during the process of the first mover shaft 211 driving the electric toothbrush head 10 to perform the first movement, the first elastic structure can generate an elastic restoring force. Before the mode switching of the electric toothbrush 100, the elastic restoring force generated by the first elastic structure can cause the first mover shaft 211 to reset to the zero-axis position A15 in the moving direction of the first movement; during the process of the second mover shaft 231 driving the electric toothbrush head 10 to perform the second movement, the second elastic structure can generate an elastic restoring force. Before the mode switching of the electric toothbrush 100, the elastic restoring force generated by the second elastic structure can cause the second mover shaft 231 to reset to the zero-axis position A25 in the moving direction of the second movement.

[0109] In some embodiments, the reset mechanism 27 includes a first magnetic structure, which includes a first magnetic member and a second magnetic member. The first magnetic member is disposed on the housing 25 of the motor 20 or the first stator 213 of the first magnetic mechanism 21, and the second magnetic member is disposed on the first mover shaft 211. The first magnetic member and the second magnetic member cooperate to provide a magnetic restoring force to the first mover shaft 211; and / or, the reset mechanism 27 includes a second magnetic structure, which includes a third magnetic member and a fourth magnetic member. The third magnetic member is disposed on the housing 25 of the motor 20 or the second stator 233 of the second magnetic mechanism 23, and the fourth magnetic member is disposed on the second mover shaft 231. The third magnetic member and the fourth magnetic member cooperate to provide a magnetic restoring force to the second mover shaft 231.

[0110] Specifically, in some embodiments, before the mode switch of the electric toothbrush 100, the circuit board 30 can output a third control signal to the first magnetic structure to generate a magnetic restoring force between the first magnetic member and the second magnetic member, so that the first mover shaft 211 is reset to the zero-axis position A15 in the moving direction of the first movement; the circuit board 30 can output a fourth control signal to the second magnetic structure to generate a magnetic restoring force between the third magnetic member and the fourth magnetic member, so that the second mover shaft 231 is reset to the zero-axis position A25 in the moving direction of the second movement.

[0111] In other embodiments, during the process that the first mover shaft 211 drives the electric toothbrush head 10 to perform the first movement, a magnetic restoring force is continuously generated between the first magnetic member and the second magnetic member. Before the mode switch of the electric toothbrush 100, this magnetic restoring force can reset the first mover shaft 211 to the zero-axis position A15 in the moving direction of the first movement; during the process that the second mover shaft 231 drives the electric toothbrush head 10 to perform the second movement, a magnetic restoring force is continuously generated between the third magnetic member and the fourth magnetic member. Before the mode switch of the electric toothbrush 100, this magnetic restoring force can reset the second mover shaft 231 to the zero-axis position A25 in the moving direction of the second movement.

[0112] Please refer to Figure 2 and Figure 3 , in some embodiments, the motor 20 further includes a detection mechanism 29 for detecting the operating parameters of the first magnetic force mechanism 21; or, the detection mechanism 29 is used to detect the operating parameters of the second magnetic force mechanism 23.

[0113] It can be understood that when the detection mechanism 29 is used to detect the operating parameters of the first magnetic force mechanism 21 and the electric toothbrush head 10 performs a unidirectional movement, the circuit board 30 outputs a first electrical signal to the first magnetic force mechanism 21 to make the first magnetic force mechanism 21 drive the electric toothbrush head 10 to perform the first movement; when the detection mechanism 29 is used to detect the operating parameters of the second magnetic force mechanism 23 and the electric toothbrush head 10 performs a unidirectional movement, the circuit board 30 outputs a second electrical signal to the second magnetic force mechanism 23 to make the second magnetic force mechanism 23 drive the electric toothbrush head 10 to perform the second movement. That is, when the electric toothbrush head 10 performs a unidirectional movement, the magnetic force mechanism with a detection function outputs power, so that the power output by the magnetic force mechanism can be controlled more precisely.

[0114] It should be noted that, in some embodiments, when the operating parameters include frequency, the detection mechanism 29 includes an angle sensor. When the operating parameters include amplitude, the detection mechanism 29 includes a magnetic force sensor for detecting an angle or a displacement length.

[0115] In some embodiments, the motor 20 further includes a housing 25. When the operating parameters include frequency or amplitude, the detection mechanism 29 includes a first detection component and a second detection component. One of the first detection component and the second detection component is disposed on the housing 25, and the other of the first detection component and the second detection component is disposed on the first magnetic mechanism 21. The first detection component and the second detection component cooperate to detect the operating parameters of the first magnetic mechanism 21; or, the other of the first detection component and the second detection component is disposed on the second magnetic mechanism 23, and the first detection component and the second detection component cooperate to detect the operating parameters of the second magnetic mechanism 23.

[0116] Specifically, in some embodiments, both the first magnetic mechanism 21 and the second magnetic mechanism 23 are disposed inside the housing 25, and the output shaft 201 can pass through the housing 25 and extend outside the housing 25 to be connected to the electric toothbrush head 10. Among them, the material of the housing 25 can be a metal material or a non-metal material. The metal materials include but are not limited to aluminum, iron, steel, or aluminum alloy, etc., and the non-metal materials include but are not limited to plastics, etc. In one example, the housing 25 can be made of a combination of metal materials and non-metal materials, thereby enabling the housing 25 to have higher structural strength, preventing the housing 25 from being damaged during the operation of the motor 20, and improving the stability and reliability of the operation of the motor 20. In another example, the housing 25 can be made of a non-metal material, thereby enabling the housing 25 to be lighter in weight, which is beneficial to the light-weighting of the motor 20 and the electric toothbrush 100.

[0117] Among them, one of the first detection component and the second detection component can be an electromagnetic sensor (such as a Hall sensor, etc.), an optoelectronic sensor (such as a laser sensor, etc.), or an ultrasonic sensor, etc., and the other of the first detection component and the second detection component can be a component that can cooperate with an electromagnetic sensor (such as a Hall sensor, etc.), an optoelectronic sensor (such as a laser sensor, etc.), or an ultrasonic sensor, etc. Thus, the first detection component and the second detection component can cooperate to jointly detect the operating parameters of the first magnetic mechanism 21 or the second magnetic mechanism 23.
