[0033] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0034] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0035] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0036] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0037] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0038] The present disclosure provides a personal care device, comprising a cleaning part, a gripping part and a transmission mechanism. The gripping part is configured to be suitable for gripping, and may include a housing, a driving unit, a control unit and other components such as a circuit board and a power supply located in the housing. The cleaning part includes at least two cleaning units, which may be, for example, a brush head or other devices with a care function.

[0039] The cleaning part is configured to be mounted together with the holding part, so that the cleaning unit can be connected to the driving unit by transmission mechanism. The cleaning part is, for example, mounted on the holding part in a detachable manner, so that when the cleaning part is worn or expires, the cleaning part can be replaced. The driving unit is configured to output an initial motion in response to one or more control signals sent by the control unit, and the initial motion output by the driving unit is converted into a motion different from the motion mode of the initial motion to at least one cleaning unit through the transmission mechanism, and the transmission mechanism also converts the initial motion output by the driving unit into a motion different from the motion mode of the initial motion to at least another cleaning unit or directly transfers the initial motion to at least another cleaning unit, so as to drive at least two cleaning units to move in two motion modes respectively, so that at least two cleaning units respectively perform cleaning actions, at least two of the multiple cleaning units have different motion modes, and the corresponding cleaning actions are different, and the motion mode of at least one cleaning unit is different from the initial motion.

[0040] The motion mode disclosed in the present invention refers to the form, state, posture or pattern of the movement of the cleaning unit. For example, it may be different movement directions, different movement methods, different movement parameters, etc. As long as the two cleaning units do not maintain exactly the same motion mode at the same time, they are all within the scope of the present disclosure and will not be listed one by one here.

[0041] In one embodiment of the present disclosure, the transmission structure is also configured to transmit the initial motion to one or more of the at least two cleaning units, so that the one or more cleaning units perform a cleaning action. Specifically, the transmission structure may not convert the motion mode of the initial motion, but only perform motion transmission, so that one or more of the at least two cleaning units maintain the same motion mode as the initial motion and perform a cleaning action. Thus, among the cleaning units included in the cleaning section, at least one cleaning unit performs a cleaning action different from the motion mode of the initial motion, and at least one cleaning unit performs the same cleaning action as the motion mode of the initial motion. The two cleaning units have different motion modes, which can provide a deeper and more adaptable cleaning for the user's oral cavity.

[0042] As an embodiment, the transmission structure converts the initial motion of the driving unit into at least one identical or different target motion, and the target motion has a different motion mode from the initial motion, thereby driving at least one cleaning unit to move and perform a cleaning action, and the motion mode of the at least one cleaning unit is different from the initial motion; at the same time, the transmission structure also directly transmits the initial motion of the driving unit to other cleaning units, which may be one or more cleaning units, thereby driving other cleaning units to perform cleaning actions, and the motion modes of the other cleaning units are the same as the initial motion. As another embodiment, the transmission structure converts the initial motion of the driving unit into at least two different target motions, thereby driving at least two cleaning units to move and perform different cleaning actions, and the motion modes of the at least two cleaning units are different from the initial motion and are also different from each other.

[0043] Compared with the traditional single motion mode, the cleaning units with different motion modes can enable the personal care device to perform deep cleaning on different parts to be cleaned at the same time, solving the problem of cleaning blind spots or low cleaning efficiency caused by different positions and shapes of the parts to be cleaned, while also meeting the diverse cleaning needs of users. In addition, the appropriate motion mode can be selected according to the shape and position of the part to be cleaned, which improves the cleaning efficiency and cleaning effect while improving the user's cleaning experience.

[0044] A cleaning section provided in the present disclosure is the cleaning section as described above, and the cleaning section includes at least two cleaning units and a transmission structure, the transmission structure is transmission-connected to the cleaning units, and converts the initial motion output by the driving unit into a motion different from the motion mode of the initial motion to at least one cleaning unit, so that the at least two cleaning units move in two motion modes respectively.

[0045] For ease of understanding, refer to Figures 1 to 11 The specific structure and working principle of the personal care device and the cleaning part of the present disclosure are described in detail in combination with an embodiment. The present disclosure provides a personal care device, which can be an electric toothbrush, a massager, a facial cleaner or other personal care devices known to those skilled in the art.

[0046] like Figure 1 As shown, the personal care device of the present disclosure includes a cleaning portion, a grip portion and a transmission mechanism.

[0047] The cleaning part of the present disclosure includes a cleaning part body and at least two cleaning units arranged on the cleaning part body, and the at least two cleaning units can clean the same area to be cleaned or different areas to be cleaned. The user holds the grip part still or moves, and the cleaning unit can continuously or discontinuously clean the surface of the cleaning part. Figure 1 In the illustrated embodiment, two cleaning units are provided, which are respectively denoted as a first cleaning unit and a second cleaning unit. The first cleaning unit and the second cleaning unit are provided on the cleaning unit body, and the movement modes of the first cleaning unit and the second cleaning unit on the cleaning unit body are different.

[0048] In the embodiment of the personal care device of the present disclosure being an electric toothbrush, the cleaning unit is a brush head unit provided with bristles, and each brush head unit can work independently or in coordination to clean different tooth surfaces and gaps. The design and arrangement of the bristles can optimize the cleaning effect, and bristles of different hardness or shapes can also be used to meet different cleaning needs, and the present disclosure does not make specific restrictions here. When the personal care device of the present disclosure is a facial massager or a fascia gun, the cleaning unit is a movable massage head, and a soft material can be provided on the surface of the massage head to avoid damaging the user's skin during cleaning.

[0049] The motion mode of the present disclosure refers to the form, state, posture or pattern of motion, etc., which may be different motion directions, different motion modes, different motion parameters, etc. For example, the first cleaning unit is rotatably connected to the cleaning body, and it can rotate on the cleaning body around its central axis; the second cleaning unit is constructed to be able to move in a straight line along the cleaning body, which makes the motion postures of the two cleaning units different. For another example, the first cleaning unit and the second cleaning unit are both rotatably connected to the cleaning body, but the two cleaning units have different rotation directions or different rotation speeds; for another example, the first cleaning unit and the second cleaning unit are constructed to swing on the cleaning body, but the two cleaning units have different swing directions, or different swing amplitudes, swing frequencies, etc. As long as the two cleaning units do not maintain exactly the same motion mode, they are all within the scope of the present disclosure and will not be listed one by one here.

[0050] Continue to refer Figure 1 The holding portion may include a housing and a driving unit, a control unit, a circuit board, a power supply and other components contained in the housing. The driving unit is configured to output an initial movement in response to one or more control signals sent by the control unit. Wherein, the cleaning portion is constructed to be mounted together with the holding portion through a transmission mechanism, thereby enabling the cleaning unit to be transmission-connected to the driving unit through the transmission mechanism. The transmission mechanism is transmission-connected to the driving unit of the holding portion. As an embodiment, the transmission structure can be detachably mounted on the driving shaft of the driving unit through structures such as snaps. In addition, the transmission structure can be arranged in the cavity of the cleaning portion body, extending in the cavity to cooperate with the cleaning unit. As an embodiment, some components of the transmission structure can be arranged on the cleaning unit or assembled with the cleaning unit, for example, on the side or back plate opposite to the cleaning surface of the cleaning unit. In one embodiment of the present disclosure, the cleaning portion is, for example, detachably mounted on the holding portion, thereby enabling the cleaning portion to be replaced when the cleaning portion is worn or expires after its service life.

[0051] Specifically, the grip part is the part for the user to hold, and the interior of the grip part contains a drive unit and a control unit. The drive unit is used to generate original power output, and the control unit is used to receive user input (such as switch button operation) or preset program, and generate a control signal according to the user input or preset program to control the working state and mode of the drive unit.

[0052] The transmission mechanism of the present disclosure is in transmission connection with the cleaning unit and is configured to convert the initial motion output by the driving unit to at least one cleaning unit, so that at least two cleaning units move in two motion modes respectively.

[0053] The driving unit converts the output initial motion into a motion different from the motion mode of the initial motion to at least one cleaning unit through a transmission mechanism, and converts the output initial motion into a motion different from the motion mode of the initial motion to at least another cleaning unit or directly transmits it to at least another cleaning unit, so that at least two cleaning units move in two motion modes respectively. Specifically, the transmission mechanism transmits and converts the initial motion output by the driving unit to the cleaning unit, so that the cleaning unit can move in two motion modes respectively, such as rotational motion or reciprocating motion, etc., so as to achieve a comprehensive cleaning effect.

[0054] Compared with the traditional single motion mode, the cleaning units with different operating modes can enable the personal care device to perform deep cleaning on different parts to be cleaned at the same time, solving the problem of blind spots or low cleaning efficiency caused by different positions and shapes of the parts to be cleaned, while also meeting the diverse cleaning needs of users. In addition, the appropriate motion mode can be selected according to the shape and position of the part to be cleaned, which improves the cleaning efficiency and cleaning effect while improving the user's cleaning experience.

[0055] The structure of the human oral cavity is complex, including the tooth side, chewing surface, groove and other areas. Due to the differences in the surface shape, position, space limitations and other factors of the teeth, in order to achieve a better cleaning effect, the brush head shape and cleaning movement mode required for cleaning each area must have diverse and specific requirements. The current mainstream electric toothbrushes mainly achieve full-effect cleaning coverage of multiple areas through a single brush head brush filament cluster shape combination design or provide multiple specific brush head components. The former solution still has limited contact effect on particularly narrow groove areas, while the latter solution requires the replacement of cleaning components during the cleaning process, which is cumbersome and complicated to operate and cannot meet the full-effect and efficient cleaning needs of different areas of the oral cavity.

[0056] In one embodiment of the present disclosure, the cleaning unit also includes one or more receiving units that cooperate with the transmission mechanism, and the one or more receiving units are connected to the one or more cleaning units, and are driven by the transmission mechanism to drive the one or more cleaning units, so that the one or more cleaning units perform cleaning actions. Specifically, the transmission mechanism converts the initial motion into one or more target motions and outputs them to the receiving unit, and the receiving unit is driven by the target motion to drive the cleaning unit to move. Of course, the transmission mechanism can also output the initial motion to the receiving unit, and the receiving unit is driven by the initial motion to drive the cleaning unit to move and perform the cleaning action. The receiving unit can adjust the power received from the transmission mechanism according to the characteristics and needs of the cleaning unit. When the cleaning unit includes multiple cleaning units, the receiving unit is also responsible for coordinating the motion between these units to ensure that they can work synchronously and complete the cleaning task together to achieve a composite motion mode. The receiving unit can be customized for different users or different cleaning needs to provide a more personalized and targeted cleaning experience.

[0057] In one embodiment of the present disclosure, the transmission structure transmits the initial motion generated by the driving unit to one of the multiple cleaning units, and the cleaning unit performs a specific cleaning action according to a specific motion state, which not only improves the cleaning effect but also ensures the safety and comfort of use. Figure 2 In one embodiment of the present disclosure, the transmission mechanism includes at least a first transmission unit 41 and a second transmission unit 42, and the cleaning section 1 includes at least a first cleaning unit 11 and a second cleaning unit 12; the first transmission unit 41 converts the initial motion into a first motion, and drives the first cleaning unit 11 to perform a first cleaning action; converts the initial motion into a second motion or transmits the initial motion to the second cleaning unit 12, and drives the second cleaning unit 12 to perform a second cleaning action; the motion modes of the first cleaning unit 11 and the second cleaning unit 12 are different. As one way, the motion mode of the first motion is different from the initial motion, and / or the motion mode of the second motion is different from the initial motion. As another way, the motion mode of the first cleaning unit 11 is different from the initial motion, and / or the motion mode of the first cleaning unit 11 is different from the initial motion.

[0058] Specifically, the first transmission unit 41 receives the initial motion from the driving unit. The first transmission unit 41 may be, but is not limited to, a connecting rod, a gear, a lever, a screw rod, a chain, a spring, etc. The first transmission unit 41 converts the initial motion into a first motion suitable for the first cleaning unit 11 to meet specific cleaning requirements. Similarly, the second transmission unit 42 also receives the same initial motion, converts the initial motion into a second motion or directly transmits it to the second transmission unit 42 to drive the second cleaning unit 12.

[0059] The transmission mechanism converts or transmits the initial motion generated by the driving unit to different cleaning units, so that they perform motions of different motion modes. Even if the driving unit only provides a single initial motion, the transmission mechanism can make the first cleaning unit 11 and the second cleaning unit 12 each perform the first cleaning action and the second cleaning action that are most suitable for their cleaning targets through the differentiated design of the first transmission unit 41 and the second transmission unit 42. For example, the first cleaning unit 11 may be designed to perform cleaning actions at a higher frequency and a smaller amplitude to deal with sensitive tooth areas, while the second cleaning unit 12 may perform cleaning actions at a lower frequency and a larger amplitude to clean harder dental plaque, ensuring that the device can efficiently and specifically clean different areas in the oral cavity.

[0060] In one embodiment of the present disclosure, the first transmission unit 41 and the second transmission unit 42 are an integrally formed structure, or are assembled and joined to form a transmission mechanism.

[0061] Specifically, when the first transmission unit 41 and the second transmission unit 42 are integrally formed, better structural stability and precision can be provided, and assembly errors and relative movement between parts can be reduced, thereby reducing noise and energy loss. When the first transmission unit 41 and the second transmission unit 42 are assembled together to form a transmission mechanism, the first transmission unit 41 and the second transmission unit 42 are assembled together through an interface or a connector to form a complete transmission mechanism. This can improve the flexibility of the transmission mechanism, and each transmission unit can be optimized independently to meet specific functional requirements or space limitations. In addition, the joint assembly is also convenient for maintenance and replacement of parts, and damaged units can be replaced separately without replacing the entire transmission mechanism.

[0062] In one embodiment of the present disclosure, the first transmission unit 41 and the second transmission unit 42 are respectively connected to the driving unit for transmission, and the first transmission unit 41 and the second transmission unit 42 are independently transmitted to each other.

[0063] Specifically, the first transmission unit 41 and the second transmission unit 42 are both directly connected to the drive unit, and can independently receive power and control signals without being affected by the other transmission unit, thereby making independent motion adjustments. Since each transmission unit can be independently controlled, the device can provide different cleaning modes for different cleaning units. For example, one cleaning unit can vibrate at a high frequency to remove stains on the surface of the teeth, while another unit can clean the gaps between teeth at a lower frequency and a larger amplitude. The independent transmission design enables the device to perform efficient cleaning at multiple cleaning points at the same time, and each point can achieve independent cleaning actions, thereby improving the overall cleaning efficiency.

[0064] In one embodiment of the present disclosure, the initial motion is reciprocating rotation, reciprocating vibration or rotation with the extended axis of the drive shaft as the rotation center.

[0065] In one embodiment of the present disclosure, the initial motion is a multimodal motion, including but not limited to: xy-axis compound motion, circumferential-axial compound motion, and two circumferential compound motions, wherein the xy-axis compound motion is an independent or coordinated compound motion in the x-axis and y-axis directions, the circumferential-axial compound motion is a compound motion of independent or coordinated rotational motion and displacement motion in the direction of extension of a preset axis, and the two circumferential compound motions are movements along two circular paths.

[0066] Specifically, the initial motion output by the driving unit is a multi-modal motion, and the multi-modal motion means that the device can execute two or more different types of motion modes.

[0067] In the XY-axis compound motion mode, the cleaning section 1 moves not only in one axis, but also in two perpendicular axes (such as the horizontal X-axis and the vertical Y-axis) at the same time. This compound motion can imitate the natural rotation and up and down movement of the wrist when brushing manually, which helps to deeply clean the gaps and crevices between teeth while covering multiple surfaces of the teeth. The circumferential-axial compound motion mode combines rotational (circumferential) and linear (axial) motion. While the cleaning section 1 rotates or reciprocates to clean the teeth, it also reciprocates along the length direction (axial) of the teeth, imitating horizontal brushing while cleaning the teeth in the up and down directions. The two circumferential compound motion modes refer to the cleaning section 1 rotating on two different circular paths at the same time. The multimodal motion form can adapt to the changes in different parts of the oral cavity and different cleaning needs, achieving more efficient and thorough cleaning.

[0068] In one embodiment of the present disclosure, the first motion and the second motion include at least one of the following differences: different motion paths, different motion frequencies, different reciprocating motion angles, and different motion strokes. In one embodiment of the present disclosure, the motion modes of the first cleaning unit 11 and the second cleaning unit 12 include at least one of the following differences: different motion paths, different motion frequencies, different reciprocating motion angles, and different motion strokes. In one embodiment of the present disclosure, the motion modes of the first cleaning action and the second cleaning action include at least one of the following differences: different motion paths, different motion frequencies, different reciprocating motion angles, and different motion strokes.

[0069] Specifically, the first movement and the second movement have different motion modes, the first cleaning unit 11 and the second cleaning unit 12 have different motion modes, and / or the first cleaning action and the second cleaning action have different motion modes, so that different cleaning units can move along different paths, move at different frequencies, reciprocate at different angles, and / or perform different strokes to adapt to different positions and shapes of teeth. For example, see Figure 2 , the second cleaning unit 12 performs a rotational motion along the outer surface of the teeth, while the first cleaning unit 11 performs a linear motion between the teeth to deeply clean the gaps between the teeth. The movement frequency of the cleaning unit can be adjusted according to the characteristics of the cleaned area. For example, the first cleaning unit 11 may vibrate at a higher frequency to effectively remove stains on the tooth surface, while the second cleaning unit 12 may work at a lower frequency to avoid irritating sensitive gums. The reciprocating motion angle refers to the maximum angle of the swing or rotation of the cleaning unit when it performs a reciprocating motion. The reciprocating motion angles of the first cleaning unit 11 and the second cleaning unit 12 are different, which can better meet the cleaning needs of different parts. For example, a smaller angle may be required to clean the tooth surface, while a larger angle may be required to clean the gaps between the teeth. The motion stroke refers to the area covered by the cleaning unit in a single motion. Different cleaning units have different motion strokes to ensure that all areas that need to be cleaned are fully covered. For example, the first cleaning unit 11 may have a longer stroke to clean a longer tooth surface, while the second cleaning unit 12 may have a shorter stroke to focus on a specific small area.

[0070] By differentiating the motion modes of the first movement and the second movement, the first cleaning unit 11 and the second cleaning unit 12 and / or the first cleaning action and the second cleaning action, diversified cleaning needs in the oral cavity are met, and a more efficient, gentle and comprehensive oral cleaning experience can be provided to meet the personalized needs of different users.

[0071] In one embodiment of the present disclosure, the motion path includes but is not limited to: a pivot path, a reciprocating rotation path, a knocking motion path, a reciprocating vibration path, a reciprocating sweeping path, a lateral linear motion, a longitudinal linear motion and / or a pendulum motion, wherein the pivot path is a path rotating around a fulcrum or pivot, the knocking motion path is the motion trajectory of the knocking point in the process of moving from the knocking point to the contact point, the lateral linear motion is a lateral motion based on the extension axis of the personal care device, the drive unit or the drive shaft, and the longitudinal linear motion is a longitudinal motion based on the extension axis of the personal care device, the drive unit or the drive shaft.

[0072] Specifically, the pivot path is a path that rotates around a fulcrum or pivot. This motion path can imitate the rotation of the wrist when brushing manually, which helps to clean all surfaces of the teeth. The reciprocating rotation path refers to the cleaning unit rotating back and forth around a center point. This path can penetrate deep into the teeth and effectively remove embedded food debris and dental plaque. The knocking motion path refers to the cleaning unit starting from a knocking point and moving quickly to the contact point, producing a slight knocking feeling. This movement can loosen stubborn plaque and tartar, and is suitable for cleaning the back teeth and chewing surfaces. The reciprocating vibration path is a high-frequency, small-angle vibration path, which means that the cleaning unit vibrates back and forth rapidly in a predetermined direction. This high-frequency vibration can promote the generation of detergent foam, increase the contact area between the detergent and the tooth surface, and improve cleaning efficiency. The reciprocating sweeping path is a low-frequency, large-angle sweeping path, which means that the cleaning unit sweeps back and forth within a range, similar to the sweeping action when brushing manually, and can clean the outer and inner sides of the teeth. Horizontal linear motion refers to the cleaning unit moving horizontally based on the extended axis of the toothbrush, which is suitable for cleaning the occlusal surface and top of the teeth and helps to remove dirt in the flat area. Longitudinal linear motion refers to the cleaning unit moving longitudinally along the extended axis of the toothbrush, which can penetrate deep into the gaps between teeth and clean the residues in the gaps between teeth. Pendulum motion refers to the cleaning unit swinging back and forth within a certain angle like a pendulum. This motion can simulate the professional cleaning techniques of dentists and provide comprehensive and gentle cleaning of teeth. Different motion paths can provide more efficient cleaning effects for different parts of the teeth and oral cavity and cleaning needs.

[0073] The personal care device of the present disclosure is applied to an electric toothbrush in the oral field. By making at least two cleaning units move in two motion modes respectively, it can achieve in-depth and efficient cleaning of various cleaning surfaces / grooves and other areas of the oral cavity, thereby meeting the diverse cleaning needs inside the oral cavity and achieving more efficient and comprehensive cleaning. For the convenience of description, the structure and working principle of the personal care device of the present disclosure are described in detail by taking an electric toothbrush as an example.

The first transmission unit 41 vibrates under the action of the power source, thereby driving the first cleaning unit 11 to vibrate back and forth. When the first transmission unit 41 drives one end of the second transmission unit 42 to vibrate, the other end of the second transmission unit 42 drives the second cleaning unit 12 to reciprocate around the rotating shaft 6.

The two opposite ends of the brush head body 3 are respectively recorded as the first end and the second end. The first cleaning unit 11 and the second cleaning unit 12 are arranged at the first end of the brush head body 3, wherein the second cleaning unit 12 is rotatably connected to the brush head body 3 through a rotating shaft 6. The transmission mechanism comprises a first transmission unit 41 and a second transmission unit 42. The first transmission unit 41 is fixed on the brush head body 3 and driven to vibrate the brush head body 3 by an external vibration source. The second transmission unit 42 is connected to the first transmission unit 41, and the connection point between the first transmission unit 41 and the second transmission unit 42 is used as a boundary. One end of the second transmission unit 42 is constructed to extend toward the first end of the brush head body 3 to be eccentrically connected to the second cleaning unit 12 through an eccentric cylinder 7, and the other end extends toward the second end of the brush head body 3 to cooperate with the limiting part arranged at the corresponding position on the grip part 2. The first transmission unit 41 is controlled by an external vibration source to drive the brush head body 3 to vibrate, and at the same time drives the first cleaning unit 11 to swing back and forth, drives the second transmission unit 42 to vibrate, and then the second transmission unit 42 drives the second cleaning unit 12 to reciprocate within a predetermined angle through the eccentric cylinder 7.

[0076] Figure 6 , Figure 7 One embodiment of the electric toothbrush disclosed in the present invention is shown. Figure 6 , Figure 7 In the embodiment, the electric toothbrush disclosed in the present invention comprises a cleaning part 1, a gripping part 2 and a transmission mechanism. The cleaning part 1 comprises a brush head body 3 and a first cleaning unit 11 and a second cleaning unit 12 arranged on the brush head body 3.

[0077] Figure 8 , Fig. 9 One embodiment of the electric toothbrush disclosed in the present invention is shown. Figure 8 , Fig. 9 In the embodiment, the electric toothbrush of the present invention comprises a cleaning part 1, a gripping part 2 and a transmission mechanism. The cleaning part 1 comprises a brush head body 3 and a first cleaning unit 11 and a second cleaning unit 12 arranged on the brush head body 3, wherein the first cleaning unit 11 and the second cleaning unit 12 are hinged on the brush head body 3. With the intersection of the first cleaning unit 11 and the second cleaning unit 12 on the brush head body 3 as the boundary, the opposite ends of the first cleaning unit 11 and the second cleaning unit 12 are respectively recorded as the first end and the second end, and the first ends of the first cleaning unit 11 and the second cleaning unit 12 are pre-pressed on the brush head body 3 by a spring 8. The transmission mechanism comprises a first transmission unit 41, and the first transmission unit 41 extends in the brush head body 3 to cooperate with the second ends of the first cleaning unit 11 and the second cleaning unit 12. During the reciprocating rotation of the first transmission unit 41 in the brush head body 3 , the first transmission unit 41 alternately applies a deflection torque to the second ends of the first cleaning unit 11 and the second cleaning unit 12 , converting the reciprocating rotation into a deflection push, so that the first cleaning unit 11 and the second cleaning unit 12 reciprocate and deflect in the brush head body 3 .

[0078] like Figure 1 As shown, in one embodiment of the present disclosure, the personal care device further includes: the control unit is configured to determine a driving parameter in response to a trigger signal, and the driving unit is configured to output an initial motion based on the driving parameter determined by the control unit.

[0079] Specifically, the trigger signal originates from the user's operation, which can be the user starting or adjusting the mode through the handle button / app control, or based on sensor sensing to start, adjust the mode and other methods. The trigger signal is the initial indication of the device starting or changing the working mode. After receiving the trigger signal, the control unit parses the trigger signal and determines the drive parameters according to the preset program or algorithm. The drive parameters are used to drive how the unit outputs the initial motion. The drive unit outputs the initial motion based on the drive parameters received from the control unit. The user can select or adjust the cleaning mode and generate a trigger signal. The control unit determines the drive parameters according to the trigger signal, thereby ensuring the cleaning effect while enabling the personal care device to adapt to the oral conditions and personal preferences of different users, providing a more personalized and efficient cleaning experience.

[0080] In one embodiment of the present disclosure, the driving unit includes a driving shaft, and the driving parameters include but are not limited to: a driving shaft rotation angle, a driving shaft rotation direction, a driving shaft reciprocating rotation frequency and / or a driving shaft target position.

[0081] Specifically, the driving unit converts electrical energy into mechanical motion to drive the cleaning part 1 to complete the cleaning action. The driving parameters include but are not limited to the rotation angle, rotation direction, reciprocating rotation frequency and target position of the driving shaft.

[0082] The drive shaft rotation angle is the angle of each rotation of the drive shaft. The size of the drive shaft rotation angle can affect the coverage and cleaning mode of the cleaning unit. For example, rapid and continuous rotation at a small angle is suitable for delicate cleaning, while rotation at a large angle can be used to remove stubborn stains. The drive shaft can rotate forward or reverse, or alternate between forward and reverse directions. Different combinations of rotation directions can produce different cleaning effects. For example, forward rotation can deeply clean the gaps between teeth, and reverse rotation helps loosen and remove dental plaque. The reciprocating rotation frequency of the drive shaft refers to the number of forward and reverse rotations of the drive shaft per unit time. On the basis of ensuring the cleaning effect, the gentleness of tooth and gum cleaning can be comprehensively considered to select the appropriate reciprocating rotation frequency of the drive shaft. The drive shaft target position refers to the position of the drive shaft during rotation and / or telescopic movements, ensuring that the cleaning unit can accurately reach or fully cover every part that needs to be cleaned.

[0083] By adjusting these drive parameters, the control unit can achieve precise control of the drive shaft movement, so that the cleaning unit can perform efficient cleaning actions. For example, in sensitive tooth areas, the control unit sets a lower rotation frequency and a smaller rotation angle, while in areas where strong cleaning is required, a higher frequency and a larger rotation angle are used. Combining user needs and the device's intelligent algorithm, personal care devices can provide an efficient and comfortable cleaning experience.

[0084] In one embodiment of the present disclosure, the initial motion is a periodic motion, and the periodic motion includes at least one or more of the following motion combinations with different parameters: a driving shaft rotation angle, a driving shaft rotation direction, and a driving shaft reciprocating rotation frequency.

[0085] Specifically, in periodic motion, the rotation angle of the drive shaft can be changed periodically. For example, the device may rotate quickly at a small angle in one cycle, and then increase the rotation angle in the next cycle to more comprehensively cover the cleaning area, which helps to flexibly switch between detailed cleaning and deep cleaning. Periodically changing the rotation direction of the drive shaft, such as switching between forward and reverse, can enhance the cleaning effect. Periodically adjusting the reciprocating rotation frequency of the drive shaft can provide cleaning of different intensities at different time periods. For example, a higher frequency is used at the beginning of cleaning to quickly remove surface dirt, and then the frequency is reduced to treat sensitive areas more gently.

[0086] Through cyclical movements with different motion combinations, not only the comprehensiveness and efficiency of cleaning are improved, but also tooth wear and gum irritation that may be caused by long-term high-intensity cleaning are reduced, achieving the dual goals of cleaning and protection.

[0087] Currently, mainstream motor toothbrushes mainly use open-loop direct-drive control motors (eccentric motors, sonic motors, linear motors, etc.) to drive the cleaning brush head to achieve high-frequency reciprocating swing or reciprocating rotation of the cleaning component for oral cleaning.

[0088] An electric toothbrush with a compound motion mode usually has one or more cleaning units on a single brush head. The brush head body 3 and the combined cleaning unit respectively perform left and right reciprocating swings, knocking, rotation, left and right or up and down movement / swings, etc. to achieve a combination of cleaning motion forms. Usually, open-loop drive motors such as eccentric motors, sonic motors or linear motors are used independently or in combination of two, and the transmission is transmitted to each cleaning unit on the brush head by structures such as connecting rods and crankshafts to achieve combined motion.

[0089] However, due to the limitations of the control principle, the movement amplitude of the motor in the open-loop drive mode cannot be precisely controlled, the movement range cannot be flexibly adjusted, and the load resistance is poor (the movement attenuation is large under high load conditions of open-loop control). The power mode transmitted by the single motor is single. Although the composite structure brush head driven by it has a variety of motion forms, due to the weak power load resistance and low efficiency of the power transmission structure, the final composite motion power is insufficient and the cleaning effect is poor. The control mode is relatively fixed and cannot be dynamically adjusted. The multi-motor combination drive brings about the problem that multiple motion modes cannot be precisely and synchronously controlled, and the regional cleaning efficiency is reduced. The current solution does not fundamentally achieve the optimal multi-modal combination cleaning method.

[0090] like Fig.11As shown, in one embodiment of the present disclosure, the driving unit includes a servo motor 9 and a driving shaft. The servo motor is placed at the front end of the grip 2 to drive the driving shaft to output power. The main control board 10 with the MCU provides control signals for the servo motor 9. The battery 13 is used to provide power. The button 14 is set with multiple gears, and the multiple gears are used to reflect the user's needs to transmit the signal to the MCU. The cleaning part 1 is sleeved on the driving shaft and receives the power output by the servo motor 9 through the built-in transmission mechanism in conjunction with the driving shaft. In this embodiment, based on the closed-loop motion control characteristics of the servo motor 9 and the design of the multi-modal cleaning element, a multi-modal cleaning component motion scheme is provided under the various driving power modes of the servo motor 9 to achieve efficient and full-effect oral cleaning.

[0091] In one embodiment of the present disclosure, since the servo motor 9 can control the swing angle or rotation of the drive shaft, it provides a rich selection for the design of the cleaning unit 1. When the servo motor 9 swings at a high frequency, the cleaning unit 1 can swing at a combination of multiple movable parts as described above, or can swing at a high frequency for a single movable part. Fig.10 As shown, when the servo motor 9 rotates at a high frequency, the cleaning part 1 can perform a variety of motion modes such as high-frequency angular swing motion, high-frequency circular rotation, etc. for a single movable part.

[0092] In one embodiment of the present disclosure, the personal care device further includes a sensing unit, which is electrically connected to the control unit. The control unit is configured to adjust the driving parameters through the electrical signal of the sensing unit so that the driving unit maintains an initial motion state.

[0093] Specifically, the sensing unit is responsible for monitoring the real-time status of the drive unit, including but not limited to position, speed, acceleration, etc. For the current position of the drive shaft, the sensing unit is a rotary encoder, Hall sensor, etc., which can accurately measure the rotation angle or position of the shaft and convert these physical quantities into electrical signals. The control unit receives the electrical signal from the sensing unit, compares it with the preset target value, and calculates the error. Based on this error signal, the control unit uses a control algorithm (such as PID control, fuzzy control, etc.) to adjust the drive parameters, such as the voltage, current or frequency of the motor, to correct the error so that the state of the drive unit tends to or remains at the set point. The closed-loop control can feedback loop, allowing the system to self-regulate and resist interference. When the system detects a deviation from the set point, the control unit responds immediately and adjusts the drive parameters to correct the deviation, thereby maintaining the stability and accuracy of the system.

[0094] When the system starts running, the control unit sets the initial motion state of the drive unit, such as speed, position or torque. The sensing unit continuously monitors the actual state, such as the current position of the drive shaft. The control unit compares the actual state with the set point and, if there is a deviation, adjusts the drive parameters until the actual state matches the set point. The system repeats the monitoring, comparison and adjustment process throughout the operation to ensure that the drive unit always maintains the desired motion state. Closed-loop control ensures high precision, high stability and high efficiency of the system.

[0095] In addition, in this embodiment, the personal care device is also provided with a Hall sensor, which can measure the magnetic field strength and is used to detect the motor position or speed. The Hall sensor can be combined with a closed-loop control system to provide more accurate drive parameter regulation. For example, by monitoring the actual position and speed of the motor, the system can adjust the frequency, swing angle and speed in real time to ensure that each cleaning action achieves the best effect.

[0096] In one embodiment of the present disclosure, the personal care device can also collect the user's brushing habits, preferences and health data, analyze these data through machine learning algorithms, and provide users with personalized cleaning solutions. For example, for users who often eat coloring foods, the device may recommend increasing the swing angle and speed to enhance the whitening effect. By regulating the drive parameters, combined with closed-loop control and sensor technology, an efficient, safe and personalized cleaning experience can be provided. This not only improves the cleaning effect, but also ensures the comfort and health of the user.

[0097] The personal care device provided by the present disclosure includes a cleaning part, a holding part and a transmission mechanism. The initial motion output by the driving unit is converted to at least one cleaning unit through the transmission structure, so that at least two cleaning units can move in two motion modes, thereby achieving in-depth and efficient cleaning of various cleaning surfaces / grooves and other areas of the oral cavity, thereby meeting the diverse cleaning needs inside the oral cavity.
