[0002] This application claims priority to Chinese Patent Application No. 2024119747208, filed on December 26, 2024, entitled "Control method, computing device, storage medium, and program product for personal care device". The entire contents of that Chinese patent application are incorporated herein by reference. Technical Field

Moreover, the collection, use and processing of related data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and corresponding operation entry points are provided for users to choose to authorize or refuse.
[0043] This disclosure provides a method for controlling a personal care device. This disclosure also relates to a computing device, a computer-readable storage medium, and a computer program product, which will be described in detail in the following embodiments.
[0044] Referring to Figures 1 and 2, according to a first aspect of this disclosure, a control method for a personal care device is provided. The personal care device includes: a cleaning unit; and a gripping unit, the gripping unit including a drive unit, a control unit, and a sensing unit housed therein. The sensing unit is electrically connected to the control unit and transmits sensed brushing posture information to the control unit. The control unit is configured to determine a target cleaning area based on the brushing posture information and generate a control signal based on corresponding drive parameters determined according to the target cleaning area. The drive unit is coupled to the cleaning unit and configured to output an initial movement corresponding to the target cleaning area in response to one or more control signals sent by the control unit, driving the cleaning unit to perform a target movement corresponding to the target cleaning area. The target movements corresponding to different cleaning areas have at least some different motion modes.
[0045] In this embodiment, the personal care device may be an electric toothbrush, a massager, a facial cleanser, or other personal care devices well known to those skilled in the art. The control method of the personal care device in this embodiment will be described below using an electric toothbrush as an example.
[0046] Referring to Figure 1, the personal care device disclosed herein includes a cleaning section and a holding section. The cleaning section is equipped with bristles that directly contact the user's tooth surface to remove food debris and plaque. The holding section is the part used by the user to grip the tooth and integrates a drive unit, a control unit, and a sensing unit. The sensing unit can be an accelerometer, gyroscope, or other type of sensor to detect the user's brushing posture information, which may include brushing angle and brushing pressure. The sensing unit can monitor the pressure applied by the user during brushing, the brushing time, and whether all tooth surfaces are covered. This not only helps to identify the target cleaning area but also helps ensure that the user does not apply excessive force, causing gum damage, and ensures that each cleaning session is sufficient in duration.
[0047] The control unit is electrically connected to the sensing unit to receive data from the sensing unit, analyze the user's current brushing posture, and determine the target cleaning area the user is currently cleaning, such as the incisor area or molar area. Based on the determined target cleaning area, the drive unit selects corresponding drive parameters to generate appropriate control signals. Responding to the control signals received from the control unit, the drive unit generates a predetermined pattern of motion, such as vibration, rotation, or a combination of pulse movements, or adjusts motion parameters, such as increasing the amplitude or adjusting the jump angle, thereby driving the cleaning unit to perform effective cleaning of the target area. Furthermore, the control unit also embeds an intelligent recognition model that can identify the user's brushing habits and optimize the cleaning strategy based on changes over time. For example, if it detects that the user frequently misses a certain cleaning area, it can adjust prompts or change the motion mode to guide the user to clean correctly.
[0048] Because different areas of a tooth have different structures, each area requires a different cleaning mode. Therefore, the target motion for each area should have at least some different motion modes. For example, horizontal vibration motion can be used for the incisors, while circular motion can be used for the molars. Selecting different cleaning modes for different areas allows for a personalized cleaning experience tailored to the user's specific needs, more thoroughly removing plaque and other stains, reducing the risk of cavities and periodontal disease, and improving cleaning efficiency. Furthermore, since different users have different oral structures, customizing the most suitable cleaning plan based on individual differences ensures that each dental cleaning is more tailored to individual needs.
[0049] In this embodiment, the personal care device has Bluetooth or other wireless communication capabilities, which allows the personal care device to be paired with a smartphone application. This not only allows for the tracking and analysis of brushing data, but also provides personalized suggestions and feedback to the user, and can even monitor oral health and share the data with a dentist for remote monitoring.
[0050] In one embodiment of this disclosure, the initial motion corresponding to different cleaning areas has at least some different motion modes.
[0051] Different cleaning areas correspond to at least some motion modes of the initial movement, resulting in at least some motion modes of the corresponding target movement. This means that personal care devices can adjust their cleaning actions according to the characteristics of different tooth areas. This differentiated cleaning mode ensures that each area receives the most effective cleaning. Examples based on different tooth areas and their corresponding motion modes are provided below.
[0052] For example, the anterior teeth area (front teeth area) is suitable for cleaning with gentle, wide-coverage movements because the surface of the front teeth is relatively flat and located at the front of the mouth. Use lateral vibrations or slight circular motions to clean the anterior teeth area (front teeth area) to ensure the surface is smooth and free of stains.
[0053] For the posterior teeth (molars), due to their complex occlusal surfaces and numerous grooves, more forceful cleaning actions are required to remove embedded food debris and plaque. Here, the occlusal surfaces automatically adjust to a polishing motion to gently but effectively clean these complex structures, ensuring that food debris and plaque are thoroughly removed.
[0054] For the sides of teeth and near the gum line, where plaque easily accumulates and is close to the gums, a gentler cleaning method is needed to ensure effective cleaning while avoiding gum irritation. Use vertical up-and-down vibrations or small-amplitude pulses for cleaning. Simultaneously, employ a combined cleaning method for the grooves and crevices on the tooth surfaces, adjusting the motion to a combination of left-and-right oscillations and reciprocating rotation. This can also increase power and adaptively adjust the cleaning mode to ensure every corner receives appropriate attention without damaging the gums.
[0055] For the areas between teeth, which are more difficult to clean, high-frequency vibrations to generate water or airflow are often used to help clean hard-to-reach grooves and crevices. High-frequency vibrations or ultrasonic pulses are used to ensure that even the smallest crevices remain clean.
[0056] For the inner surfaces of teeth, due to their smaller contact area and irregular shape, the angle of the brush head needs to be adjusted flexibly to ensure effective cleaning. Optimal cleaning results are achieved by combining adaptive angle adjustments with moderate circular motions.
[0057] In this way, personal care devices can provide users with a more personalized and efficient cleaning experience, automatically switching motion modes based on different cleaning areas, which not only improves cleaning efficiency but also takes into account the user's comfort and safety.
[0058] In one embodiment of this disclosure, the motion mode of the initial motion corresponding to different cleaning areas includes at least one of the following differences: different motion paths, different motion frequencies, different reciprocating angles, and different motion distances.
[0059] Different initial motion modes result in at least some different target motion modes. Specifically, personal care devices can select different initial motion modes based on different cleaning areas, as illustrated below.
[0060] For different motion paths:
[0061] The anterior teeth can use horizontal or slightly inclined straight-line motion paths, while the posterior teeth can use more circular motion or more complex curved paths to better cover the occlusal surfaces and grooves.
[0062] For different motion frequencies:
[0063] For sensitive areas, such as the area near the gum line, lower frequency movements can be used to reduce irritation to the gums; for non-sensitive areas, such as the molar area, higher frequency rapid vibrations or rotations can be used to more thoroughly remove food debris and plaque.
[0064] For different reciprocating angles:
[0065] The outer tooth surface is relatively flat and requires only small angle changes; the inner tooth surface has an irregular shape and a smaller contact area, requiring greater angle adjustments to ensure that personal care devices can clean every corner.
[0066] For different exercise distances:
[0067] The space between teeth is relatively narrow, so shorter but more frequent strokes can be used, with the water or air flow generated by high-frequency vibrations to assist in cleaning; for large areas of tooth surface, such as the front teeth, longer strokes can be used to ensure that the entire surface is cleaned evenly.
[0068] In one embodiment of this disclosure, the path of the initial motion includes, but is not limited to, one or more combinations of axial motion and circumferential motion.
[0069] Specifically, axial motion refers to the reciprocating or continuous linear motion of the brush head along its own axis. This can be used for cleaning between teeth and polishing tooth surfaces. High-frequency axial vibration helps remove food debris embedded in the gaps between teeth, achieving an effect similar to using dental floss. Slower axial motion can be used to gently polish tooth surfaces, reducing roughness. Circumferential motion refers to the rotational or circular motion of the brush head around its axis. Stronger circumferential motion can be used to clean the occlusal surfaces, helping to thoroughly remove food debris and plaque from the complex occlusal surfaces of posterior teeth. For larger and flatter surfaces such as anterior teeth, circumferential motion provides broad cleaning coverage, ensuring every corner is thoroughly cleaned. Furthermore, in this embodiment, axial and circumferential motions can be combined to form a composite cleaning action. For example, a certain frequency of circumferential rotational motion can be performed first, followed by axial vibration. This composite cleaning action can clean multiple surfaces of the teeth simultaneously, improving cleaning efficiency. Based on the user's oral structure and personal habits, the device can dynamically adjust the ratio of axial and circumferential motions to provide the most suitable cleaning solution for specific areas.
[0070] By flexibly combining axial and circumferential movements, personal care devices can provide more diverse cleaning methods tailored to the characteristics of different cleaning areas. For example, when cleaning anterior teeth, the device may use larger circumferential movements to cover the entire tooth surface, while when dealing with the complex occlusal surfaces of posterior teeth, it may increase axial vibration to deeply clean the grooves. For sensitive areas near the gum line, the device may reduce the intensity of the movements and optimize the ratio of the two movements to ensure safe and effective cleaning.
[0071] In one embodiment of this disclosure, the initial motion is a multimodal motion, including but not limited to: xy-axis composite motion, circumferential-axial composite motion, and composite motion of two circumferential directions.
[0072] The xy-axis compound motion involves the brush head moving simultaneously or alternately in two mutually perpendicular directions, forming a complex two-dimensional motion path. For the anterior teeth (front teeth area), due to its relatively flat surface and location at the front of the mouth, personal care devices can initiate the xy-axis compound motion as the initial motion mode, ensuring that every corner of the tooth surface is reached, making it particularly suitable for cleaning the anterior teeth and their flat surfaces. By controlling the amplitude and frequency of the xy-axis motion, food debris between teeth can be effectively removed without damaging the gums.
[0073] The circumferential-axial compound motion combines rotational motion around the brush head axis (circumferential motion) and linear motion along the brush head axis (axial motion). For the posterior teeth (molars), due to the complex occlusal surfaces and numerous grooves, a more powerful and thorough cleaning action is required. Personal care devices here may switch to the circumferential-axial compound motion as the initial motion mode, utilizing rapid circumferential rotation combined with high-frequency axial vibration to thoroughly clean the grooves and fissures of the occlusal surfaces. Slower circumferential rotation combined with gentle axial motion can help polish the tooth surface, reducing surface roughness and making teeth smoother. The initial motion mode in this area differs significantly from that in the anterior teeth area in terms of motion frequency, reciprocating angle, and stroke.
[0074] The two-circumferential compound motion consists of two independent but coordinated circumferential movements, which may involve different rotational speeds, directions, or angles. When cleaning the area near the gum line and the inner surfaces of teeth, the personal care device adjusts to a gentler two-circumferential compound motion as the initial motion modality. These two independent but coordinated circumferential movements may involve different rotational speeds, directions, or angles; for example, a fast circumferential rotation is used for large-area cleaning, while a slower and more precise circumferential motion focuses on details such as the tooth edges and the area near the gum line. This setup simulates the effect of a hand massage, promoting blood circulation in the gums and enhancing gum health. The initial motion modality used here is mainly reflected in the different reciprocating angles and strokes to ensure that good cleaning results are achieved without irritating sensitive gums.
[0075] By employing multimodal motion, personal care devices can provide a highly customized cleaning experience based on different areas and characteristics of the user's oral cavity.
[0076] In one embodiment of this disclosure, the cleaning unit includes at least two cleaning units, and the target motion includes the motion of at least two cleaning units; the personal care device also includes a transmission mechanism attached to a drive unit, the transmission mechanism being tractively connected to the cleaning units and configured to transfer the initial motion output by the drive unit to at least one cleaning unit, driving at least two cleaning units to move in two different motion modes respectively.
[0077] The cleaning unit is used to clean the tooth surface. The cleaning unit contains at least two cleaning units, which can be equipped with different types of bristles to meet the cleaning needs of different cleaning areas. The shapes of the at least two cleaning units can be the same or different. For example, the cleaning unit whose main cleaning action is vibration can be set as a rectangle, and the cleaning unit whose main cleaning action is rotation can be set as a circle, etc.
[0078] The drive unit is the power source of the entire system, responsible for outputting the initial motion. Depending on specific design requirements, the drive source can be a sonic motor (outputting reciprocating vibration), a bidirectional motor (capable of reciprocating vibration and / or extension), or a servo motor (capable of 360-degree rotation). A transmission mechanism is attached to the drive unit, converting the initial motion output by the drive unit into the target motion and transmitting it to each cleaning unit, driving at least two cleaning units to move in two different motion modes. The initial motion modes corresponding to different cleaning areas can be the same or different.
[0079] For example, when using a single drive source, because it needs to simultaneously power multiple cleaning units, one motor needs to work with multiple transmission mechanisms. Therefore, the transmission mechanisms can be switched manually via buttons or electronically via automatic switching to ensure that each cleaning unit can execute a specific motion mode. One cleaning unit can perform axial vibration or combined x and y axis motion for cleaning large areas and flat surfaces; another cleaning unit performs circumferential rotation or a combination of both circumferential motions, focusing on fine cleaning of the occlusal surfaces or near the gingival line. If the system is equipped with multiple motors, each motor can correspond to a separate cleaning unit, thereby simplifying the transmission structure and improving efficiency.
[0080] For individuals with diverse tooth shapes and positions, especially those with complex restorations (such as crowns, bridges) or orthodontic appliances, the personal care device disclosed herein offers a more comprehensive and meticulous cleaning. The device dynamically adjusts the operating mode of each cleaning unit based on the user's oral map and personal habits, achieving a highly customized cleaning effect. Whether designed with a single or multiple drive sources, the device aims to ensure that all cleaning units effectively adapt to the needs of different oral regions, providing the best cleaning experience.
[0081] In one embodiment of this disclosure, at least two cleaning units include a first cleaning unit and a second cleaning unit, wherein the first cleaning unit moves in different cleaning areas with different motion modes; and / or, the second cleaning unit moves in different cleaning areas with different motion modes.
[0082] Specifically, at least two cleaning units may include a first cleaning unit and a second cleaning unit, and the first cleaning unit and the second cleaning unit may have different motion modes when moving on different cleaning areas.
[0083] For example, the first cleaning unit can perform different motion modes in different cleaning areas to ensure optimal cleaning results. For the anterior teeth (incisors), gentle xy-axis compound motion or circumferential rotation can be used to cover a large and flat tooth surface and gently remove plaque. For the posterior teeth (molars), a stronger circumferential-axial compound motion is used, utilizing a combination of rotation and vibration to thoroughly clean the complex occlusal surfaces and grooves. Near the gingival line, the motion intensity is reduced and the motion mode is optimized, for example, using slight circumferential rotation combined with slow axial vibration to protect sensitive gingival tissue.
[0084] The second cleaning unit can also perform different motion modes in different cleaning areas, or work in conjunction with the first cleaning unit to provide more complex and efficient cleaning modes. For example, for interdental spaces, the second cleaning unit can perform high-frequency axial vibrations to help remove food debris embedded in the gaps, similar to the effect of using dental floss. For the inner surfaces of teeth, a combination of larger angle adjustments and moderate circular motions can be used to ensure that every corner is cleaned. For the sides of teeth and near the gum line, the second cleaning unit can use vertical up-and-down vibrations or small-amplitude pulse movements to ensure thorough cleaning while avoiding irritation to the gums.
[0085] By combining the different motion modes of the first and second cleaning units, the device can dynamically adjust the working mode of each cleaning unit according to the user's oral structure and personal habits, achieving a highly customized cleaning effect. For example, in the comprehensive cleaning mode, when the user begins brushing, the device activates the xy-axis compound motion of the first cleaning unit to cover a large area of the tooth surface, while the second cleaning unit performs high-frequency axial vibration to clean between teeth. In the fine cleaning mode, when moving to the posterior teeth, the first cleaning unit switches to circumferential-axial compound motion, while the second cleaning unit continues high-frequency vibration to ensure that each area is thoroughly cleaned. In the gum care mode, for sensitive areas near the gum line, both cleaning units may work together with gentle circumferential rotation and axial vibration to ensure cleaning effectiveness without causing unnecessary pressure on the gums.
[0086] By controlling the movement of each cleaning unit, the device ensures that every area of the teeth receives the most effective cleaning, reducing the risk of plaque and cavities. The combination of multimodal motion and multiple cleaning units provides a gentler yet more efficient cleaning process, reducing potential damage to the gums and other soft tissues. Furthermore, based on the user's specific oral condition and usage habits, the device can provide customized cleaning programs to help users develop good oral hygiene habits. In addition, by intelligently distributing power to different cleaning units, the device can save energy while ensuring cleaning effectiveness and extending battery life.
[0087] In one embodiment of this disclosure, the motion modes of at least two cleaning units include at least one of the following differences: different motion paths, different motion frequencies, different reciprocating angles, and different motion strokes.
[0088] To ensure that the two cleaning units of a personal care device can provide efficient cleaning in different cleaning areas, each cleaning unit's motion mode must include at least one of the following differences: different motion paths, different motion frequencies, different reciprocating angles, or different motion strokes. The following explains in detail how combinations of these differences achieve personalized and efficient cleaning:
[0089] Different motion paths refer to the different trajectories followed by the cleaning units when performing cleaning tasks. For example, the transmission mechanism converts the initial motion into a combined xy-axis motion or circumferential rotational motion to the first cleaning unit, suitable for cleaning large areas and flat surfaces, such as the anterior teeth. This allows the brush head to move simultaneously or alternately in two mutually perpendicular directions, forming a complex two-dimensional motion path to reach every corner of the tooth surface. The transmission mechanism drives the second cleaning unit to perform high-frequency axial vibration or a more complex curved path to remove food debris between teeth or clean the complex occlusal surfaces of posterior teeth.
[0090] Different movement frequencies refer to different numbers of vibrations or rotations per unit of time. For example, the first cleaning unit may use lower frequency movements in sensitive areas such as near the gum line to reduce irritation to the gums. The second cleaning unit, for areas requiring more thorough cleaning, such as the molar area, can use higher frequency rapid vibrations or rotations to ensure deep cleaning.
[0091] The different reciprocating angles refer to the different maximum deflection angles of the cleaning units during their reciprocating motion. For example, the first cleaning unit, used on the outer tooth surfaces, may only require a smaller angle change because these surfaces are relatively flat. The second cleaning unit, used on the inner tooth surfaces or irregular shapes near the gum line, may require a larger angle adjustment to ensure that every corner is cleaned.
[0092] Different stroke lengths refer to the varying distances the cleaning units travel throughout the entire cleaning cycle. For example, the first cleaning unit may use a longer stroke for larger, flat surfaces such as the front teeth to ensure even cleaning of the entire surface. The second cleaning unit, targeting interdental spaces or other narrow areas, may use shorter but more frequent strokes, utilizing high-frequency vibrations to generate water or airflow to assist in cleaning.
[0093] By flexibly combining the different motion modes of the first and second cleaning units, intelligent personal care devices can provide users with a more scientific, efficient, and personalized cleaning experience. With advancements in related technologies, we can expect more innovative features to be introduced into such products in the future, further improving users' oral health management.
[0094] In one embodiment of this disclosure, the motion path includes, but is not limited to: pivoting path, reciprocating rotation path, striking motion path, reciprocating vibration path, reciprocating sweeping path, lateral linear motion, longitudinal linear motion and / or pendulum motion.
[0095] Specifically, the two cleaning units of a personal care device can employ a variety of complex motion paths to optimize cleaning effectiveness for different dental areas. These motion paths include, but are not limited to: pivoting paths, reciprocating rotational paths, tapping motion paths, reciprocating vibrational paths, reciprocating sweeping paths, lateral linear motion, longitudinal linear motion, and / or pendulum motion.
[0096] The pivoting path involves the cleaning unit rotating around a fixed point. For example, the anterior teeth area is suitable for cleaning large areas and flat surfaces, ensuring that each tooth surface is cleaned evenly, while the inner tooth surfaces help to adapt to irregular shapes, ensuring that every corner is cleaned.
[0097] The reciprocating rotation path involves the cleaning unit rotating back and forth within a certain angle range. For example, in the complex structure of the posterior teeth, especially the occlusal surface, this path can help remove plaque from grooves and fissures. Gentle reciprocating rotation near the gingival line can massage the gums and promote blood circulation.
[0098] The tapping motion path involves the cleaning unit moving rapidly up and down at a certain frequency, simulating a tapping motion. For example, high-frequency tapping between teeth can help remove food debris embedded in the gaps, similar to the effect of using dental floss, while gentle tapping at the root of the teeth helps remove hard-to-reach areas. The reciprocating vibration path involves the cleaning unit vibrating rapidly back and forth within a small range. For example, slower reciprocating vibrations can be used to gently polish the tooth surface, reducing surface roughness, while high-frequency vibrations can deeply clean stains on the tooth surface and near the gum line.
[0099] A reciprocating sweeping path involves the cleaning unit moving back and forth in a certain direction to create a sweeping effect. For example, the anterior teeth area requires horizontal or vertical reciprocating sweeping to help thoroughly clean the tooth surface, especially for larger, flat areas. The area near the gum line requires gentle reciprocating sweeping to protect the gums while cleaning.
[0100] Lateral linear motion refers to the cleaning unit moving in a straight line along the horizontal direction. For example, it is suitable for covering large and flat tooth surfaces in the anterior teeth area, ensuring that each area is cleaned evenly. Vertical linear motion refers to the cleaning unit moving in a straight line along the vertical direction. For example, on the sides of the teeth and near the gum line, vertical linear motion can clean the sides of the teeth while avoiding irritation to the gums.
[0101] The pendulum motion acts like a pendulum, swinging the cleaning unit back and forth to create an arc-shaped path. For example, in the posterior teeth area, the pendulum motion can effectively cover the complex occlusal surfaces, ensuring that grooves and fissures are cleaned. Near the gum line, the gentle pendulum motion can massage the gums while cleaning, promoting health.
[0102] By combining these multiple motion paths, personal care devices can dynamically adjust the working mode of each cleaning unit according to the needs of different cleaning areas, providing a highly customized cleaning experience. For example, in comprehensive cleaning mode, when the user begins brushing, the first cleaning unit can use a pivoting path to cover the entire surface of the front teeth, while the second cleaning unit performs high-frequency reciprocating vibrations to clean between teeth. In fine cleaning mode, when moving to the back teeth, the first cleaning unit switches to a pendulum motion, while the second cleaning unit continues with a tapping motion to ensure that each area is thoroughly cleaned. In gum care mode, for sensitive areas near the gum line, both cleaning units may work together using a reciprocating rotational path and gentle tapping motion, ensuring cleaning effectiveness without causing unnecessary pressure on the gums.
[0103] By flexibly combining the different movement paths of multiple cleaning units, personal care devices can provide users with a more scientific, efficient, and personalized cleaning experience.
[0104] In one embodiment of this disclosure, the sensing unit includes an attitude sensor.
[0105] Personal care devices (such as smart toothbrushes) can monitor and analyze a user's brushing posture in real time to ensure that each cleaning action is accurately targeted to the intended area. Posture sensors can provide key information such as brushing angle, direction, and pressure, helping the device dynamically adjust its cleaning strategy to improve cleaning efficiency and protect oral health.
[0106] First, the posture sensor can accurately measure the angle of the brush head relative to the teeth. For example, when the brush head forms an angle of about 45 degrees with the tooth surface, it usually indicates that the user is cleaning the front teeth area; when the brush head is close to the occlusal surface and the angle is larger (e.g., 60-90 degrees), it indicates that the user is cleaning the back teeth area; when the brush head has a small angle change (e.g., within 30 degrees), it may indicate that the user is cleaning the side teeth.
[0107] Secondly, by detecting the direction of the brush head's movement, the device can determine whether the user has correctly covered all tooth surfaces. For example, a horizontal or vertical linear motion of the brush head is usually used to clean the anterior teeth; a complex curved path or pendulum motion is more common in the posterior teeth; and a slight reciprocating sweep or slow circumferential rotation is used to clean the area near the gum line.
[0108] In addition, by combining data from accelerometers and gyroscopes, the three-dimensional positional changes of the brush head within the mouth can be tracked. For example, when the brush head moves over a large area from side to side, it indicates that the user is cleaning the front teeth; when the brush head enters the deeper parts of the mouth and makes a smaller range of movement, it is cleaning the back teeth; and when the brush head makes fine movements in narrow spaces, it is cleaning between the teeth.
[0109] For example, when a user is cleaning the front teeth area, the posture sensor detects that the brush head forms an angle of approximately 45 degrees with the tooth surface, and the brush head moves a wide range of lateral or longitudinal motion within the mouth. Based on the current brushing posture information, the control unit determines that the target cleaning area is the front teeth area, and then drives the cleaning head to rotate alternately in both directions (rotation direction), maintaining a small rotation angle, using a moderate rotation speed, and gentle torque to ensure comprehensive coverage and effective cleaning of a flat surface.
[0110] When the user moves to clean the posterior teeth area, the posture sensor detects that the brush head is approaching the occlusal surface at a large angle (60-90 degrees). The brush head enters the deep part of the oral cavity and makes a small range of movements. Based on the new brushing posture information, the control unit switches the cleaning section to a larger rotation angle, increases the rotation speed, and adds appropriate torque to ensure effective cleaning of complex occlusal surfaces.
[0111] In summary, by comprehensively utilizing the brushing posture information provided by posture sensors, smart personal care devices not only improve cleaning efficiency but also enhance the user experience, making daily oral care more scientific and rational.
[0112] In one embodiment of this disclosure, the sensing unit further includes a pressure sensor, and the sensing unit is also used to sense the pressure information applied to the personal care device and transmit the sensed pressure information to the control unit; the control unit is also used to determine the corresponding drive parameters and generate a control signal based on the target cleaning area and the pressure information.
[0113] To improve the accuracy of the sensing unit in detecting the tooth area, the sensing unit also includes a pressure sensor. The pressure sensor senses the pressure applied by the personal care device and transmits the sensed pressure information to the control unit. The control unit determines the corresponding drive parameters and generates control signals based on the target cleaning area and the pressure information, as follows:
[0114] When the posture sensor detects that the brush head is at approximately a 45-degree angle and the pressure is moderate, the control unit confirms that the user is cleaning the front teeth area; when the posture sensor detects that the brush head is close to the occlusal surface at a larger angle and the pressure sensor displays moderate pressure, the control unit confirms that the user is cleaning the back teeth area; when the posture sensor detects a small angle change and the pressure sensor displays gentle pressure, the control unit confirms that the user is cleaning the lateral tooth surfaces; when the posture sensor detects a small angle change and the pressure sensor displays very gentle pressure, the control unit confirms that the user is cleaning near the gum line; when the posture sensor detects a very small angle change and the pressure sensor displays moderate pressure, the control unit confirms that the user is cleaning between the teeth.
[0115] The control unit's workflow is as follows: It receives real-time information from posture and pressure sensors to understand the current brushing posture and applied pressure. Based on changes in the brush head's angle, direction, position, and pressure, it determines the specific tooth area the user is currently cleaning. Selecting drive parameters includes choosing the most suitable rotation direction based on the target cleaning area's needs; setting an appropriate rotation angle to adapt to different tooth surface shapes; adjusting the rotation speed according to the characteristics of the cleaning area to ensure optimal cleaning results; and adjusting the torque based on pressure information to avoid excessive force or insufficient cleaning. The control unit converts the selected drive parameters into specific control signals and sends them to the drive unit. Throughout the brushing process, the control unit continuously monitors the sensor data and dynamically adjusts the drive parameters as needed to ensure optimal cleaning results and user experience.
[0116] When the user is cleaning the front teeth area, the posture sensor detects that the brush head forms an angle of approximately 45 degrees with the tooth surface, and the pressure sensor displays moderate pressure. Based on the current brushing posture information, the control unit confirms that the current cleaning area is the front teeth area, and initiates bidirectional alternating rotation of the cleaning head (rotation direction), maintaining a small rotation angle, using a moderate rotation speed, and gentle torque to ensure comprehensive coverage and effective cleaning of a flat surface.
[0117] When the user moves towards the posterior teeth area, the posture sensor detects that the brush head is approaching the occlusal surface at a relatively large angle (60-90 degrees), and the pressure sensor displays moderate pressure. Based on the new posture and pressure information, the control unit determines that the current cleaning area is the posterior teeth area, switches the first cleaning unit to a larger rotation angle, increases the rotation speed, and adds appropriate torque to ensure effective cleaning of the complex occlusal surfaces. If the user applies excessive pressure, the control unit will issue an alarm to remind the user and temporarily reduce the rotation speed and torque until the pressure returns to normal.
[0118] In one embodiment of this disclosure, the control unit determines drive parameters based on the target cleaning area, wherein the drive parameters include, but are not limited to: rotation direction, rotation angle, rotation speed and / or torque.
[0119] To ensure the personal care device delivers the most efficient cleaning results in different cleaning areas, the control unit determines the drive parameters based on the target cleaning area. These drive parameters include, but are not limited to, rotation direction, rotation angle, rotation speed, and / or torque. Furthermore, the device adjusts the rotation speed and the amplitude of the vibrating element through duty cycle control for more precise control. Correspondingly, the motor rotation direction determines the vibration and rotation direction of the cleaning element in the brush head; the central angle of the motor rotation determines the amplitude or central angle of rotation of the cleaning element; the rotation speed determines the frequency of vibration or rotation of the cleaning element; and the torque determines the cleaning force of the cleaning element.
[0120] The direction of rotation refers to the direction in which the cleaning unit rotates, which can be clockwise or counterclockwise. For the anterior teeth area, alternating directions of rotation can be used to ensure coverage of the entire tooth surface and avoid applying excessive pressure in one direction. For the complex occlusal surfaces of the posterior teeth area, a specific direction of rotation can be selected to better accommodate grooves and fissures. The direction of motor rotation directly affects the vibration or rotation direction of the cleaning elements in the brush head, thereby optimizing the cleaning effect on different areas.
[0121] The rotation angle refers to the maximum deflection angle achieved by the cleaning unit in a single rotation. Smaller rotation angles are typically required for the outer tooth surfaces because these surfaces are relatively flat and have a large contact area. Larger rotation angles are needed for the inner tooth surfaces and near the gum line to better accommodate irregular shapes and clean every corner. The central angle of the motor's rotation determines the amplitude or central angle of rotation of the brush head's cleaning elements, allowing the transmission mechanism to precisely adjust the range of motion of each cleaning unit to meet the needs of different oral cavity areas.
[0122] Rotation speed refers to the number of rotations per unit time. For sensitive areas, such as near the gum line, a lower rotation speed may be used to reduce irritation to the gums. For the posterior teeth, a higher rotation speed may be used because a more thorough removal of food debris and plaque is required. The rotation speed determines the frequency of vibration or rotation of the cleaning elements in the brush head. By adjusting the motor speed, the control unit can flexibly adjust the cleaning efficiency to ensure a gentle yet effective cleaning.
[0123] Torque refers to the magnitude of the force generated when the cleaning unit rotates. For interdental areas, high-frequency vibration combined with appropriate torque can help remove food debris embedded in the gaps, similar to the effect of using dental floss. For large areas of the tooth surface, lighter torque can be used to gently polish the tooth surface, reducing surface roughness. Torque determines the cleaning force of the cleaning elements in the brush head, ensuring that appropriate pressure is provided for different cleaning needs.
[0124] When the user is cleaning the front teeth area, the posture sensor detects that the brush head is contacting the teeth at a 45-degree angle, and the pressure sensor indicates that the applied pressure is moderate. The control unit confirms that the current posture and pressure are suitable for the area, and then initiates bidirectional alternating rotation of the cleaning unit (rotation direction), maintaining a small rotation angle, a moderate rotation speed, and gentle torque to ensure comprehensive coverage and effective cleaning of a flat surface. Simultaneously, by adjusting the duty cycle, the control unit can also fine-tune the rotation speed and the amplitude of the vibration element to further optimize the cleaning experience.
[0125] When the user moves towards the posterior teeth area, the posture sensor detects a change in the brush head angle, indicating it is approaching the occlusal surface, and the pressure sensor displays appropriate pressure. Based on the new posture and pressure information, the control unit switches the cleaning section to a larger rotation angle, increases the rotation speed, and adds appropriate torque to ensure effective cleaning of complex occlusal surfaces. If the user applies excessive pressure, the control unit will issue an alarm to remind the user and temporarily reduce the rotation speed and torque until the pressure returns to normal. In this situation, the duty cycle control mechanism also plays a crucial role, allowing the system to respond quickly and adjust to a safe and effective cleaning mode.
[0126] In summary, by precisely adjusting drive parameters such as rotation direction, rotation angle, rotation speed, and torque, intelligent personal care devices not only improve cleaning efficiency but also enhance the user experience. Utilizing the characteristics of the motor's rotation direction, central angle, speed, and torque, the control unit can dynamically adjust the cleaning mode, providing users with highly customized cleaning solutions to ensure optimal cleaning results for every area of the oral cavity while protecting gum health.
[0127] In one embodiment of this disclosure, the initial motion is a periodic motion, and the periodic motion corresponding to different cleaning areas has at least some different motion modes.
[0128] Periodic motion refers to the cleaning unit repeating the same motion pattern according to a certain regularity. This motion can be simple reciprocating motion, rotational motion, or more complex combinations of motion. The key is that the motion parameters (such as rotation direction, angle, speed, and torque) within each cycle can be adjusted according to the needs of the target cleaning area.
[0129] The cyclical motion design for the anterior teeth area features gentle lateral linear motion or circumferential rotation. Its cyclical characteristics include alternating bidirectional rotation to ensure full coverage, small angular variations suitable for flat surfaces, moderate rotational speeds that effectively clean without excessive pressure on the gums, and gentle torque to reduce irritation near the gingival line. This combination ensures a gentle yet effective cleaning of the anterior teeth area.
[0130] The cyclical movements in the posterior teeth region employ strong pendulum motion or circumferential-axial composite motion, with cyclic characteristics including unidirectional or bidirectional rotation, flexibly adjusted according to the complexity of the occlusal surface. Larger rotation angles accommodate complex grooves and fissures, higher rotational speeds ensure deep cleaning, while moderate torque effectively removes plaque without damaging enamel. This design ensures thorough cleaning of the posterior teeth region.
[0131] The cyclical movements near the gum line consist of slight circumferential rotation combined with slow axial vibration. The cyclical characteristics include gentle unidirectional or bidirectional rotation to avoid overstimulating the gums. Small angle changes focus on fine cleaning around the gum line, the low rotational speed protects sensitive gum tissue, and the very gentle torque prevents unnecessary pressure on the gums, thus achieving gentle yet effective cleaning.
[0132] The periodic movements between teeth primarily rely on high-frequency axial vibrations or tapping motions, possibly accompanied by slight circumferential rotation. The minimal rotation angle focuses on cleaning narrow spaces, and the high-frequency vibrations mimic the effect of dental floss, ensuring the removal of embedded food debris. Moderate torque provides sufficient force for deep cleaning while avoiding damage to teeth and gums. This design ensures thorough cleaning between teeth.
[0133] In one embodiment of this disclosure, the periodic motion includes one or more motions with different modes. The periodic motions corresponding to different cleaning areas include at least one of the following differences: different number of motions, different output order of motions with the same mode, or different modes of at least one motion.
[0134] The periodic movements of the anterior teeth include two modes: gentle lateral linear motion and slight circumferential rotation. Each cycle contains both modes, making it suitable for cleaning large areas of overbite and flat surfaces. In contrast, the periodic movements of the posterior teeth are more complex, including three or more modes: strong pendulum motion, circumferential-axial compound motion, and high-frequency vibration, ensuring thorough cleaning of complex occlusal surfaces and grooves.
[0135] The periodic movements near the gingival line consist of slight circumferential rotation and slow axial vibration. The periodic characteristics are: first, circumferential rotation to cover the gingival line, followed by axial vibration to massage the gums and protect sensitive tissues. The periodic movements between teeth, on the other hand, begin with high-frequency vibration to remove food debris, followed by tapping motions to ensure deep cleaning. Both areas have the same movement modality but different output sequences, optimizing the cleaning effect in their respective areas.
[0136] The periodic movements on the outer tooth surfaces employ moderate lateral linear motion and gentle circumferential rotation. The lateral linear motion covers a large surface area, while the circumferential rotation is used for fine cleaning of the edges. The periodic movements on the inner tooth surfaces use a larger rotation angle and a slight pendulum motion. The larger rotation angle accommodates irregular shapes, and the pendulum motion ensures cleaning of every corner. This demonstrates that different areas have at least one different movement mode to meet their respective cleaning needs.
[0137] The control unit first receives real-time information from the attitude and pressure sensors to determine the specific area of the teeth the user is currently cleaning. Next, based on the needs of the target cleaning area, it selects the optimal number of movements, modes, and their output sequence to ensure that the movement modes within each cycle conform to the best cleaning strategy for that area. Finally, the control unit generates specific control signals and sends them to the drive unit, continuously monitoring the sensing data throughout the brushing process and dynamically adjusting the drive parameters to ensure optimal cleaning results and user experience.
