Description

Technical Field

[0001] The present application relates to the field of personal care technology, and in particular to an oral cleaning device, method, and storage medium. Background Art

[0002] With the development of intelligent electric products, more and more people use electric oral cleaning devices for daily oral cleaning due to their convenience. During the oral cleaning process, in order to improve the cleaning effect of the oral cavity, different oral cleaning actions are usually required to clean different oral areas.

[0003] However, existing electric oral cleaning devices are unable to accurately identify the oral area. Summary of the Invention

[0004] The main purpose of the embodiments of the present application is to provide an oral cleaning device, method and storage medium, which aim to accurately identify the oral area to be cleaned or currently cleaned in the user's mouth, so as to improve the oral cleaning effect.

[0005] In a first aspect, an embodiment of the present application provides an oral cleaning device, comprising:

[0006] a housing, wherein the housing forms a receiving space;

[0007] a driving component, the driving component being at least partially accommodated in the accommodating space and at least used to drive the cleaning component to clean a target area in the user's oral cavity;

[0008] A posture sensor, used to obtain posture information of the oral cleaning device;

[0009] a distance sensor for acquiring relative position information between the oral cleaning device and a target part of a user, wherein the distance sensor comprises a signal transmitting component for transmitting a signal and a signal receiving component for receiving a signal;

[0010] A controller is communicatively connected to the driving component, the posture sensor, and the distance sensor, and is at least used to:

[0011] controlling the posture sensor to obtain first posture information of the oral cleaning device;

[0012] Controlling the signal transmitting component to transmit a first signal, and controlling the signal receiving component to receive a second signal obtained by reflecting the first signal from a target part of the user;

[0013] obtaining first relative position information between the oral cleaning device and the target part based on at least the second signal;

[0014] A target area in the user's oral cavity is obtained, wherein the target area is an oral cavity area currently to be cleaned or currently being cleaned, and at least a portion of the target area is determined based on at least the first posture information and the first relative position information.

[0015] In this embodiment, when the user is cleaning the oral cavity with the oral cleaning device, the oral cleaning device can accurately locate each target area in the oral cavity through the posture sensor and the distance sensor to avoid misidentification of the target area, so that the oral cleaning device can accurately clean each target area, thereby effectively improving the cleaning effect of the oral cavity, and avoiding the positioning error caused by only using the posture sensor to locate part of the target area to be cleaned or currently cleaned in the oral cavity, which ultimately causes inaccurate target area identification, resulting in some oral areas not being cleaned and some oral areas being over-cleaned.

[0016] In some embodiments, after acquiring the target area in the user's oral cavity, the controller is further configured to:

[0017] A target cleaning strategy matching the target area is acquired, and the oral cleaning device is controlled to clean the target area in the user's oral cavity using the target cleaning strategy.

[0018] In this embodiment, different target areas are cleaned using a target cleaning strategy adapted to the target area, which can effectively improve the cleaning effect of the corresponding target area.

[0019] In some embodiments, the controller obtains the target area in the user's oral cavity, including:

[0020] The target area of the user's mouth is determined based on at least the first posture information and the first relative position information.

[0021] In this embodiment, each target area in the oral cavity to be cleaned or currently being cleaned can be obtained by the oral cleaning device through analysis of the first posture information and the first relative position information, without the aid of external equipment.

[0022] In some embodiments, the controller obtains the target area in the user's oral cavity, including:

[0023] controlling the oral cleaning device to send the first posture information and the first relative position information to a terminal device communicatively connected to the oral cleaning device;

[0024] Receive the target area in the user's mouth determined by the terminal device at least based on the first posture information and the first relative position information.

[0025] In this embodiment, the target areas to be cleaned or currently cleaned in the oral cavity can be obtained by analyzing the first posture information and the first relative position information by a terminal device connected to the oral cleaning device for communication, without increasing the data analysis burden of the oral cleaning device.

[0026] In some embodiments, the target cleaning strategy includes at least a target cleaning time corresponding to the target area. When controlling the oral cleaning device to clean the target area in the user's oral cavity using the target cleaning strategy, the controller is further configured to:

[0027] Calculating a cleaning time corresponding to a cleaning operation performed by the oral cleaning device in the current target area using the target cleaning strategy;

[0028] When the cleaning time is greater than or equal to the target cleaning time, the oral cleaning device and / or the terminal device connected to the oral cleaning device for communication outputs a first prompt, wherein the first prompt is used to prompt the user to switch the target area for cleaning, or to prompt the user that the current cleaning time of the target area is too long.

[0029] In this embodiment, during the process of the oral cleaning device cleaning the target area, the cleaning time corresponding to the cleaning operation of the cleaning device in the target area is recorded, and when the cleaning time is greater than or equal to the target cleaning time, a first prompt is output through the oral cleaning device or the terminal device, thereby avoiding the user from performing cleaning operations on the same target area of the oral cavity for a long time, causing wear and tear on the cleaned object (such as teeth and gums).

[0030] In some embodiments, the controller is also used to: when the cleaning time is less than the target cleaning time and the oral cleaning device cleans another target area in the user's mouth that is different from the target area, control the oral cleaning device and / or a terminal device that is communicatively connected to the oral cleaning device to output a second prompt.

[0031] In this embodiment, during the process of the oral cleaning device cleaning the target area, the cleaning time corresponding to the cleaning operation of the cleaning device in the target area is recorded. When the cleaning time is less than the target cleaning time, the cleaning effect of the target cleaning part in the oral cavity may be poor. Therefore, a second prompt is output through the oral cleaning device or the terminal device so that the user can adjust the oral cleaning device in time to perform the cleaning operation to improve the cleaning effect of the oral cavity.

[0032] In some embodiments, the target cleaning strategy includes at least a target cleaning action corresponding to cleaning the target area. When controlling the oral cleaning device to clean the target area in the user's oral cavity using the target cleaning strategy, the controller is further configured to:

[0033] Acquiring second posture information of the oral cleaning device collected by the posture sensor;

[0034] determining, based on the second posture information, whether a cleaning action corresponding to the cleaning of the target area by the oral cleaning device matches the target cleaning action;

[0035] When the cleaning action corresponding to the cleaning of the target area by the oral cleaning device does not match the target cleaning action, the oral cleaning device and / or a terminal device communicatively connected to the oral cleaning device is controlled to output a third prompt.

[0036] In this embodiment, during the process of the oral cleaning device cleaning the target area of the oral cavity, the posture information of the oral cleaning device collected by the posture sensor is obtained, and then the posture information is used to determine whether the cleaning action corresponding to the current user operating the oral cleaning device to clean the target area is standard. If the cleaning action is not standard, it may cause poor cleaning effect and even cause wear of the cleaned object (such as teeth and gums). Therefore, when the cleaning action is not standard, the oral cleaning device or terminal device outputs a corresponding prompt to prompt the user to adjust the cleaning action in time.

[0037] In some embodiments, the target cleaning strategy includes at least a target cleaning action corresponding to cleaning the target area. When controlling the oral cleaning device to clean the target area in the user's oral cavity using the target cleaning strategy, the controller is further configured to:

[0038] Acquiring second posture information of the oral cleaning device collected by the posture sensor and second relative position information between the oral cleaning device and the target part of the user collected by the distance sensor;

[0039] determining, based on the second posture information and the second relative position information, whether a cleaning action corresponding to the cleaning of the target area by the oral cleaning device matches the target cleaning action;

[0040] When the cleaning action corresponding to the cleaning of the target area by the oral cleaning device does not match the target cleaning action, the oral cleaning device and / or a terminal device communicatively connected to the oral cleaning device is controlled to output a third prompt.

[0041] In this embodiment, during the process of the oral cleaning device cleaning the target area of the oral cavity, the posture information of the oral cleaning device collected by the posture sensor and the relative position information collected by the distance sensor are obtained, and the posture information and relative position information are used to comprehensively judge whether the cleaning action corresponding to the current user's operation of the oral cleaning device to clean the target area is standard. If the cleaning action is not standard, it may cause poor cleaning effect and even cause wear of the cleaned object (such as teeth and gums). Therefore, when the cleaning action is not standard, the oral cleaning device or terminal device outputs a corresponding prompt to prompt the user to adjust the cleaning action in time.

[0042] In some embodiments, the oral cleaning device further includes a pressure sensor communicatively connected to the controller, the target cleaning strategy includes at least a target cleaning pressure corresponding to cleaning the target area, and when controlling the oral cleaning device to clean the target area in the user's oral cavity using the target cleaning strategy, the controller is further configured to:

[0043] Acquiring pressure sensing information output by the pressure sensor;

[0044] determining, based on the pressure sensing information, whether the cleaning pressure corresponding to the cleaning of the target area by the oral cleaning device matches the target cleaning pressure;

[0045] When the cleaning pressure corresponding to the cleaning of the target area by the oral cleaning device does not match the target cleaning pressure, the oral cleaning device and / or a terminal device communicatively connected to the oral cleaning device is controlled to output a fourth prompt.

[0046] In this embodiment, a pressure sensor is provided in the oral cleaning device. During the process of the oral cleaning device cleaning the target area of the oral cavity, the cleaning pressure of the user operating the oral cleaning device for cleaning is obtained through the pressure sensor, and when the cleaning pressure is too large or too small, a corresponding prompt is output through the oral cleaning device or the terminal device, so that the user can adjust the cleaning pressure in time to reduce the adverse effects of poor cleaning effect due to too low cleaning pressure or reduce the adverse effects of wear on the cleaned object (such as teeth and gums) caused by too high cleaning pressure.

[0047] In some embodiments, the controller is further configured to: obtain cleaning progress information of the oral cleaning device for cleaning each target area in the user's oral cavity; and control the oral cleaning device to output a cleaning progress prompt of the user's oral cleaning and / or the target area currently being cleaned in the user's oral cavity according to the cleaning progress information;

[0048] Alternatively, cleaning progress information of the oral cleaning device cleaning each target area in the user's mouth is obtained; and according to the cleaning progress information, a terminal device communicating with the oral cleaning device is controlled to output a cleaning progress prompt of the user's oral cleaning, at least one of the target area currently being cleaned in the user's mouth, the target area that has been cleaned, or the target area that has not been cleaned.

[0049] Optionally, the oral cleaning device is provided with a display component, and the controller controls the oral cleaning device to output a cleaning progress prompt of the user's oral cleaning according to the cleaning progress information, including:

[0050] According to the cleaning progress information, the display component of the oral cleaning device is controlled to display the cleaning progress prompt of the user's oral cleaning and update the cleaning progress prompt, wherein the cleaning progress prompt includes at least one of the cleaning progress percentage, the cleaning progress bar, the cleaning progress ring, and the cleaning progress text information.

[0051] Optionally, the oral cleaning device is provided with a display component, and the controller controls the oral cleaning device to output the target area currently being cleaned in the user's oral cavity according to the cleaning progress information, including:

[0052] According to the cleaning progress information, the display component of the oral cleaning device is controlled to display the target object model of the user's oral cavity to be cleaned or currently cleaned, and the target area currently being cleaned is highlighted, wherein the target object model includes multiple target areas, and the target area currently being cleaned can be updated and displayed according to the cleaning progress information.

[0053] In this embodiment, during the process of the oral cleaning device cleaning the target area of the oral cavity, the cleaning progress information of the oral cleaning device cleaning the target area in the oral cavity is obtained, and the corresponding cleaning progress prompt and at least one of the target areas currently being cleaned are output through the oral cleaning device and / or a terminal device communicated with the oral cleaning device, so that the user can promptly know the current cleaning progress or the target area currently being cleaned through the cleaning progress prompt.

[0054] Furthermore, the cleaning progress prompt or the current cleaning target area is visually displayed and updateable through the display component, thereby enhancing the visibility of the cleaning operation and effectively improving the user's oral cleaning experience.

[0055] In some embodiments, after the oral cleaning device completes cleaning of each target area in the user's oral cavity, the controller is further configured to:

[0056] Controlling the oral cleaning device to stop working;

[0057] Alternatively, the oral cleaning device is controlled to stop working and output a fifth prompt and / or a terminal device communicatively connected to the oral cleaning device is controlled to output a fifth prompt.

[0058] In this embodiment, after the oral cleaning device completes cleaning of all target areas in the oral cavity, the oral cleaning device is automatically controlled to stop working, which can effectively improve the user's oral cleaning experience.

[0059] In some embodiments, after the oral cleaning device completes cleaning of each target area in the user's oral cavity, the controller is further configured to:

[0060] Obtaining a region cleaning score corresponding to cleaning each target region in the user's oral cavity using the target cleaning strategy matching the target region;

[0061] The cleaning score of the oral cleaning process is calculated according to the regional cleaning score corresponding to each target area.

[0062] Optionally, the controller obtains the area cleaning score corresponding to each target area in the user's oral cavity being cleaned using the target cleaning strategy matching the target area, including:

[0063] Calculating a deviation value between a corresponding cleaning action and a target cleaning action during a cleaning process in which each target area is cleaned using the target cleaning strategy matching the target area;

[0064] A region cleaning score corresponding to the target region is determined according to the deviation value.

[0065] In this embodiment, during the process of the oral cleaning device cleaning the target area of the oral cavity, one or more sensors arranged in the oral cleaning device detect relevant information during the cleaning process of each target area, such as, relevant information including but not limited to at least one of cleaning action, cleaning time, cleaning pressure, and cleaning amplitude, so as to obtain the regional cleaning score of each target area cleaned using the target cleaning strategy through analysis of the relevant information, and finally the cleaning score of this oral cleaning process can be calculated based on the regional cleaning score of each target area, so that the user can judge whether the current cleaning operation is reasonable through the cleaning score.

[0066] In some embodiments, after the oral cleaning device completes cleaning of each target area in the user's oral cavity, the controller is further configured to:

[0067] Obtaining cleaning results corresponding to cleaning of each target area in the user's oral cavity using the target cleaning strategy that matches the target area;

[0068] Determining whether the cleaning state of the corresponding target area is abnormal according to the cleaning result corresponding to the target area;

[0069] The terminal device in communication with the oral cleaning apparatus is controlled to display that the cleaning state corresponding to the target area is abnormal.

[0070] Optionally, the controller controls a terminal device in communication with the oral cleaning apparatus to display that the cleaning state corresponding to the target area is abnormal, including:

[0071] The terminal device in communication with the oral cleaning apparatus is controlled to display a target object model in the user's oral cavity to be cleaned or currently being cleaned, wherein the target object model includes multiple target areas and highlights the target area with abnormal cleaning status.

[0074] In the target object model, a first color is used to display a target area with an abnormal cleaning state, and a second color is used to display a target area with a normal cleaning state. The first color and the second color are not used.

[0075] In this embodiment, during the process of the oral cleaning device cleaning the target area of the oral cavity, one or more sensors provided in the oral cleaning device detect relevant information during the cleaning process of each target area, such as relevant information including but not limited to at least one of cleaning action, cleaning time, cleaning pressure, and cleaning amplitude, thereby analyzing the relevant information to obtain the cleaning result of each target area using the corresponding target cleaning strategy, and judging whether the corresponding target area has an abnormal cleaning state based on the cleaning result, such as the abnormal cleaning state including but not limited to at least one of excessive cleaning pressure, too low cleaning pressure, too high cleaning amplitude, too low cleaning amplitude, too long cleaning time, too short cleaning time, and cleaning action not meeting the standard. When the corresponding target area in the oral cavity has an abnormal cleaning state, the target area with the abnormal cleaning state is highlighted so that the user can perform corresponding treatment measures, thereby improving the effect of oral cleaning.

It should be noted that the oral cavity regions can also be divided in other ways. Figure 2 It only shows one embodiment of the division and is not intended to limit the oral region.

[0125] Illustratively, the oral cleaning device 100 divides the oral cavity into areas, and the area division methods include but are not limited to: 6 oral areas, 8 oral areas, 12 oral areas, 14 oral areas, 16 oral areas, 32 oral areas, etc.

[0126] For example, Figure 2 As shown, the oral cleaning device 100 divides the oral area according to the 16 area positions commonly used in the target medical industry, and divides the user's mouth into 16 oral areas, among which the oral area to be cleaned or currently cleaned (also called currently being cleaned) is called the target area.

[0127] For example, the 16 oral regions specifically include "anterior buccal surface of the maxilla", "anterior lingual surface of the maxilla", "left buccal surface of the maxilla", "left lingual surface of the maxilla", "left occlusal surface of the maxilla", "right buccal surface of the maxilla", "right lingual surface of the maxilla", "right occlusal surface of the maxilla", "anterior buccal surface of the mandible", "anterior lingual surface of the mandible", "left buccal surface of the mandible", "left lingual surface of the mandible", "left occlusal surface of the mandible", "right buccal surface of the mandible", "right lingual surface of the mandible" and "occlusal surface of the mandible".

[0128] In these 16 oral regions, if the posture information of the oral cleaning device 100 obtained by the posture sensor 30 is analyzed, since the acceleration directions of some oral regions collected by the posture sensor 30 are the same, it is possible that the posture information obtained by the posture sensor 30 at the "left buccal surface of the maxilla" and at the "right lingual surface of the maxilla" are highly similar. The posture information obtained at the "left lingual surface of the maxilla" is highly similar to that obtained at the "right buccal surface of the maxilla". The posture information obtained at the "left buccal surface of the mandible" is highly similar to that obtained at the "right lingual surface of the mandible". The posture information obtained at the "left lingual surface of the mandible" is highly similar to that obtained at the "right buccal surface of the mandible".

[0129] That is, if positioning analysis is performed only based on the posture information of the oral cleaning device 100 obtained by the posture sensor 30, the "left buccal surface of the maxilla" and the "right lingual surface of the maxilla" may be misidentified. For example, in practice, the oral area to be cleaned or currently being cleaned by the oral cleaning device 100 (i.e., the target area) is the "right lingual surface of the maxilla." Due to errors in recognition accuracy, the "left buccal surface of the maxilla" may be identified as the "right lingual surface of the maxilla." Similarly, the "left lingual surface of the maxilla" and the "right buccal surface of the maxilla" may be misidentified. The "left buccal surface of the mandible" and the "right lingual surface of the mandible" may be misidentified. The "left lingual surface of the mandible" and the "right buccal surface of the mandible" may be misidentified, causing the oral cleaning device 100 to misidentify the oral area currently being cleaned, or the oral cleaning device 100 to misidentify the oral area to be cleaned or currently being cleaned. Ultimately, some oral areas may not be cleaned, and some oral areas may be over-cleaned. Excessive cleaning for a long time may cause wear on the gums or teeth.

[0130] Therefore, positioning analysis based solely on the posture information of the oral cleaning device 100 acquired by the posture sensor 30 cannot accurately locate the portion of the user's oral cavity to be cleaned or currently being cleaned. That is, among the 16 oral regions, there may be errors in recognition accuracy when locating a portion of the oral cavity as the portion to be cleaned or currently being cleaned, making it impossible to accurately identify that portion of the oral cavity. In other words, there is a defect of inaccurate positioning of some target regions.

[0131] Similarly, the oral cleaning device 100 can also divide the user's oral cavity into 14 oral regions, specifically including "anterior buccal surface of the maxillary bone", "anterior lingual surface of the maxillary bone", "left buccal surface of the maxillary bone", "left lingual surface of the maxillary bone", "upper occlusal surface", "right buccal surface of the maxillary bone", "right lingual surface of the maxillary bone", "anterior buccal surface of the mandible", "anterior lingual surface of the mandible", "left buccal surface of the mandible", "left lingual surface of the mandible", "lower occlusal surface", "right buccal surface of the mandible", "right lingual surface of the mandible", etc. If positioning analysis is performed only by the posture information of the oral cleaning device 100 obtained by the posture sensor 30, the 14 oral region division method may also result in misidentification in the 16 oral region division method.

[0132] Alternatively, the oral cleaning device 100 can also divide the user's oral cavity into 6 oral regions, specifically "upper left teeth", "upper right teeth", "lower left teeth", "lower right teeth", "upper incisors" and "lower incisors". Among them, the inner side of the "upper left teeth" is equivalent to the "left lingual surface of the maxillary bone" in the 14 or 16-region division method, the outer side of the "upper left teeth" is equivalent to the "left buccal surface of the maxillary bone" in the 14 or 16-region division method, the inner side of the "upper right teeth" is equivalent to the "right lingual surface of the maxillary bone" in the 14 or 16-region division method, and the outer side of the "upper right teeth" is equivalent to the "right buccal surface of the maxillary bone" in the 14 or 16-region division method.

[0133] Similarly, the inner side of the "lower left tooth" is equivalent to the "left lingual surface of the mandible" in the 14 or 16 area division method, the outer side of the "lower left tooth" is equivalent to the "left buccal surface of the mandible" in the 14 or 16 area division method, the inner side of the "lower right tooth" is equivalent to the "right lingual surface of the mandible" in the 14 or 16 area division method, and the outer side of the "lower right tooth" is equivalent to the "right buccal surface of the mandible" in the 14 or 16 area division method.

[0134] That is, in some cases, if positioning analysis is performed only through the posture information of the oral cleaning device 100 obtained by the posture sensor 30, the 6-oral area division method may also cause misidentification in the 14 or 16-oral area division method.

[0135] In summary, for ease of understanding, in the embodiment of the present application, the oral cleaning device 100 is taken as an example to illustrate the division of the oral cavity into 16 regions, but the oral cleaning device 100 is not limited to dividing the oral cavity into only 16 regions.

[0136] In order to accurately identify the target area when the user uses the oral cleaning device 100 for oral cleaning, the oral cleaning device 100 of the present application collects the first posture information of the oral cleaning device 100 during the oral cleaning process through the posture sensor 30, wherein the first posture information may include the movement speed and direction of the oral cleaning device 100, the acceleration magnitude and direction of the oral cleaning device 100, and the angular velocity magnitude and direction of the oral cleaning device 100, etc.

[0137] At the same time, the signal transmitting component 401 of the distance sensor 40 is controlled to transmit a first signal, and the signal receiving component 402 is controlled to receive a second signal obtained by reflecting the first signal from the user's target area, and at least the first relative position information between the oral cleaning device 100 and the target area is obtained based on the second signal. This allows the user to accurately locate the oral area currently being cleaned or to be cleaned by the oral cleaning device 100, i.e., the target area, through comprehensive analysis of the first posture information and the first relative position information. The first relative position information can be obtained based on the analysis of the second signal, or based on a comprehensive analysis of the second signal and the first signal.

[0138] For example, through analysis of the first posture information, it is found that the oral cleaning device 100 may currently be cleaning the "left buccal surface of the maxillary bone" or the "right lingual surface of the maxillary bone", that is, the target area is the "left buccal surface of the maxillary bone" or the "right lingual surface of the maxillary bone".

[0139] Furthermore, the sensing data collected by the distance sensor 40 corresponding to the target area being the "left buccal surface of the maxillary bone" and the target area being the "right lingual surface of the maxillary bone" are different, that is, the first relative position information finally obtained is different. For example, when the oral cleaning device 100 cleans the "left buccal surface of the maxillary bone" as the target area in the oral cavity, after the signal transmitting component of the distance sensor 40 transmits a first signal with a first intensity, the signal receiving component of the distance sensor 40 receives a second signal with a second intensity. The second signal is the first signal reflected back from the target part of the user. At least after analyzing the received second signal, the first relative position information corresponding to the "left buccal surface of the maxillary bone" is X. Alternatively, after analyzing the transmitted first signal and the received second signal, the first relative position information corresponding to the "left buccal surface of the maxillary bone" is X.

[0140] Similarly, when the oral cleaning device 100 cleans the "right lingual surface of the maxillary bone" as the target area in the oral cavity, after the signal transmitting component of the distance sensor 40 transmits a first signal with a first intensity, the signal receiving component of the distance sensor 40 receives a second signal with a third intensity. The second signal is the first signal reflected back from the target part of the user. After at least analyzing the transmitted first signal and the received second signal, the first relative position information corresponding to the "right lingual surface of the maxillary bone" is Y.

[0141] After obtaining the sensor data collected by the distance sensor 40, if the analysis shows that the first relative position information is X or is adapted to X, it indicates that the target area is the "left cheek surface of the maxillary bone", that is, the oral cleaning device 100 is cleaning the "left cheek surface of the maxillary bone", or the oral area to be cleaned or currently cleaned is the "left cheek surface of the maxillary bone", wherein the first relative position information is adapted to X including but not limited to the value corresponding to the first relative position information being within the range of X, or the difference between the value corresponding to the first relative position information and X being less than a preset value.

[0142] If the analysis shows that the first relative position information is Y, or is adapted to Y, it indicates that the target area is the "right lingual surface of the maxillary bone", that is, the oral cleaning device 100 is cleaning the "right lingual surface of the maxillary bone", or the oral area to be cleaned or currently cleaned is the "right lingual surface of the maxillary bone", wherein the adaptation of the first relative position information to Y includes but is not limited to the numerical value corresponding to the first relative position information being within the range of Y, or the difference between the numerical value corresponding to the first relative position information and Y is less than the preset value.

[0143] Therefore, through the first relative position information, the corresponding target area can be accurately analyzed from the "left cheek surface of the maxillary bone" and the "right lingual surface of the maxillary bone", so that the controller 70 can control the oral cleaning device 100 to adopt an adaptive cleaning strategy to clean the target area, thereby achieving effective and precise cleaning of the user's mouth.

[0144] It can be understood that the controller 70 obtains the target area in the user's mouth by analyzing it within the oral cleaning device 100, or by analyzing it through an external device, such as a terminal device that is communicatively connected to the oral cleaning device 100, and after the analysis results are fed back to the oral cleaning device 100, the oral cleaning device 100 obtains it based on the analysis results fed back by the terminal device.

[0145] In this embodiment, when the user is cleaning the oral cavity through the oral cleaning device 100, the oral cleaning device 100 can accurately locate each target area in the oral cavity through the posture sensor 30 and the distance sensor 40 to avoid misidentification of the target area, so that the oral cleaning device 100 can accurately clean each target area, thereby effectively improving the cleaning effect of the oral cavity, and avoiding the positioning error caused by only locating part of the target area in the oral cavity through the posture sensor, which ultimately causes inaccurate target area identification, resulting in some oral areas not being cleaned and some oral areas being over-cleaned.

[0146] In some embodiments, the controller 70 acquires the target area in the user's oral cavity, including:

[0147] The controller 70 determines a corresponding target area in the user's mouth based on at least the first posture information and the first relative position information.

[0148] Exemplarily, the oral cleaning device 100 stores an application or program for analyzing the first posture information and the first relative position information. After obtaining the first posture information and the first relative position information, the controller 70 can analyze the first posture information and the first relative position information by calling a preset application or program, so that the corresponding target area can be determined from the 16 oral areas of the user's mouth.

[0149] In this embodiment, each target area in the oral cavity to be cleaned or currently being cleaned can be obtained by the oral cleaning device 100 through analysis of the first posture information and the first relative position information, without the aid of external equipment.

[0150] In some embodiments, the controller 70 acquires the target area in the user's oral cavity, including:

[0151] controlling the oral cleaning device 100 to send the first posture information and the first relative position information to a terminal device that is communicatively connected to the oral cleaning device 100;

[0152] Receive the target area in the user's mouth determined by the terminal device at least based on the first posture information and the first relative position information.

[0153] See also Figure 3 For example, the oral cleaning device 100 is communicatively connected to the terminal device 200, wherein the communication connection method can be a wired connection through a data cable, or a wireless communication method such as Bluetooth, WiFi, local area network, etc., which is not limited here.

[0154] Optionally, the terminal device may include but is not limited to: computers, smart phones, tablet computers, laptops, intelligent voice interaction devices, smart home appliances, vehicle-mounted terminals, and smart wearable devices.

[0155] Optionally, the terminal device may also be a server, which may be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server.

[0156] For ease of understanding, in the embodiments of the present application, the terminal device 200 is described as a smartphone, but the terminal device 200 is not limited to being only a smartphone.

[0157] Exemplarily, the terminal device 200 stores an application or program for analyzing the first posture information and the first relative position information. After the oral cleaning device 100 obtains the first posture information and the first relative position information, the controller 70 controls the oral cleaning device 100 to send the first posture information and the first relative position information to the terminal device 200. The terminal device 200 can analyze the first posture information and the first relative position information by calling a preset application or program, so as to determine the target area from the 16 oral areas of the user's mouth, and send the target area to the oral cleaning device 100, so that the oral cleaning device 100 can clean the target area or perform other corresponding operations.

[0158] In this embodiment, the target areas to be cleaned or currently cleaned in the oral cavity can be obtained by analyzing the first posture information and the first relative position information by the terminal device 200 that is communicatively connected to the oral cleaning device 100, without increasing the data analysis burden of the oral cleaning device 100.

[0159] In some embodiments, each oral region to be cleaned or currently cleaned in the user's oral cavity includes at least a first type of region and a second type of region, and the first type of region and the second type of region are located at different positions in the user's oral cavity;

[0160] In the process of acquiring the target area in the user's oral cavity, the controller is used to:

[0161] determining, based on the first posture information, whether the oral region corresponding to the cleaning component in the user's oral cavity belongs to the first type of region or the second type of region;

[0162] When the oral area corresponding to the cleaning component is an oral area in the first type of area, determining a candidate area to be cleaned or currently cleaned from the first type of area according to the first posture information, and determining the target area in the user's oral cavity from the candidate area according to the first relative position information;

[0163] When the oral region corresponding to the cleaning component is an oral region in the second type of region, the target region in the user's oral cavity is determined from the second type of region according to the first gesture information.

[0164] For example, when the user operates the oral cleaning device 100 to perform oral cleaning, four oral areas of the 16 oral areas, namely the "anterior buccal surface of the maxillary bone", "anterior lingual surface of the maxillary bone", "anterior buccal surface of the mandible", and "anterior lingual surface of the mandible", can be more accurately distinguished through the posture information of the oral cleaning device 100 collected by the posture sensor 30. Therefore, the above four oral areas are collectively referred to as the second type of areas.

[0165] Among the 16 oral regions, 12 parts including "left buccal surface of maxillary bone", "left lingual surface of maxillary bone", "left occlusal surface of maxillary bone", "right buccal surface of maxillary bone", "right lingual surface of maxillary bone", "right occlusal surface of maxillary bone", "left buccal surface of mandible", "left lingual surface of mandible", "left occlusal surface of mandible", "right buccal surface of mandible", "right lingual surface of mandible" and "occlusal surface of mandible" are distinguished by the posture information of the oral cleaning device 100 collected by the posture sensor 30. It is possible that the "left buccal surface of maxillary bone" and "right lingual surface of maxillary bone" are misidentified. There is misidentification between the "left lingual surface of maxillary bone" and "right buccal surface of maxillary bone". There is misidentification between the "left buccal surface of mandible" and "right lingual surface of mandible". There is misidentification between the "left lingual surface of mandible" and "right buccal surface of mandible". Additional sensors are needed for auxiliary identification, such as the distance sensor 40 for further judgment. Therefore, the 12 oral regions are collectively referred to as the first type of regions.

[0166] When the user operates the oral cleaning device 100 to clean the oral cavity, the controller 70 first determines whether the oral area currently to be cleaned or currently cleaned in the user's oral cavity belongs to the first type area or the second type area based on the posture information obtained by the posture sensor 30.

[0167] The oral cleaning device 100 stores an application or program for analyzing the first posture information and the first relative position information. When the oral area currently to be cleaned or currently being cleaned in the user's oral cavity is an oral area in the first type of area, the controller 70 calls the corresponding application or program to first determine the candidate area currently to be cleaned or currently being cleaned in the user's oral cavity from the first type of area based on the first posture information, and then determines the target area from the candidate area based on the first relative position information. For example, through analysis of the first posture information, it is determined that the oral cleaning device 100 may currently be cleaning the "left buccal surface of the maxillary bone" or the "right lingual surface of the maxillary bone", that is, the candidate area currently to be cleaned or currently being cleaned in the user's oral cavity of the oral cleaning device 100 is the "left buccal surface of the maxillary bone" or the "right lingual surface of the maxillary bone".

[0168] Furthermore, because the sensor data collected by the distance sensor 40 corresponding to the candidate regions of "left buccal surface of the maxilla" and "right lingual surface of the maxilla" are different, the resulting first relative position information is different. Therefore, the first relative position information collected by the distance sensor can more accurately obtain the corresponding target region from the candidate regions of "left buccal surface of the maxilla" or "right lingual surface of the maxilla."

[0169] When the oral area to be cleaned or currently cleaned in the user's mouth is an oral area in the second type of area, the controller 70 calls the corresponding application or program to directly determine the target area in the user's mouth from the second type of area based on the first posture information, without the need for further judgment with the help of the distance sensor 40.

[0170] In some embodiments, each oral region to be cleaned or currently cleaned in the user's mouth includes at least a first type of region and a second type of region, and the first type of region and the second type of region are located at different positions in the user's mouth.

[0171] In the process of acquiring the target area in the user's oral cavity, the controller is used to:

[0172] determining, based on the first posture information, whether the oral region corresponding to the cleaning component in the user's oral cavity belongs to the first type of region or the second type of region;

[0173] When the oral area corresponding to the cleaning component is an oral area in the first type of area, the first posture information and the first relative position information are sent to the terminal device 200 communicatively connected to the oral cleaning device 100, so that the terminal device 200 determines the candidate area currently to be cleaned or currently cleaned in the user's oral cavity from the first type of area according to the first posture information, and determines the target area in the user's oral cavity from the candidate area according to the first relative position information, and sends it to the oral cleaning device 100;

[0174] When the oral area to be cleaned or currently cleaned in the user's mouth is an oral area in the second type of area, the first posture information and the first relative position information are sent to the terminal device 200 that is communicatively connected to the oral cleaning device 100, so that the terminal device 200 determines the target area in the user's mouth from the second type of area based on the first posture information, and sends the target area to the oral cleaning device 100.

[0175] Exemplarily, unlike the aforementioned embodiment, the terminal device 200 that is communicatively connected to the oral cleaning device 100 stores an application or program for analyzing the first posture information and the first relative position information. After the oral cleaning device 100 obtains the first posture information and the first relative position information, the controller 70 controls the oral cleaning device 100 to send the first posture information and the first relative position information to the terminal device 200. The terminal device 200 can analyze the first posture information and the first relative position information by calling a preset application or program, thereby determining a target area from the 16 oral areas of the user's mouth and sending the target area to the oral cleaning device 100.

[0176] In some embodiments, after acquiring the target area in the user's oral cavity, the controller 70 is further configured to:

[0177] A target cleaning strategy matching the target area is acquired, and the oral cleaning device 100 is controlled to clean the target area in the user's oral cavity using the target cleaning strategy.

[0178] For example, in order to improve the cleaning effect of the target area, different target areas are cleaned using a target cleaning strategy adapted to the target area.

[0179] Optionally, the method of obtaining a target cleaning strategy that matches the target area includes: after obtaining the target area, the controller 70 determines the target cleaning strategy corresponding to cleaning the target area based on the association between the target area and the corresponding target cleaning strategy stored in the oral cleaning device 100.

[0180] Optionally, the method of obtaining a target cleaning strategy that matches the target area includes: after obtaining the target area, the controller 70 transmits the target area to the terminal device 200 that is communicatively connected to the oral cleaning device 100, so that the terminal device 200 determines the target cleaning strategy corresponding to the cleaning of the target area based on the received target area and the association between the target area and the corresponding target cleaning strategy stored in the terminal device 200, and sends the target cleaning strategy to the oral cleaning device 100.

[0181] Optionally, the method of obtaining a target cleaning strategy that matches the target area includes: after obtaining the target area, the terminal device 200 determines the target cleaning strategy corresponding to cleaning the target area based on the target area and the association relationship between the target area and the corresponding target cleaning strategy stored in the terminal device 200, and sends the target cleaning strategy to the oral cleaning device 100.

[0182] After obtaining the corresponding target cleaning strategy, the controller 70 controls the oral cleaning device 100 to adopt the target cleaning strategy to clean the target area. For example, the target cleaning strategy corresponding to the target area being the "left buccal surface of the maxilla" is cleaning strategy 1, and the target cleaning strategy corresponding to the target area being the "right lingual surface of the maxilla" is cleaning strategy 2. If it is identified that the oral area to be cleaned or currently cleaned by the oral cleaning device 100 is the "left buccal surface of the maxilla", the controller 70 controls the oral cleaning device 100 to adopt cleaning strategy 1 to clean the oral area that is the target area.

[0183] Similarly, if it is identified that the oral area to be cleaned or currently cleaned by the oral cleaning device 100 is the "right lingual surface of the maxillary bone", the controller 70 controls the oral cleaning device 100 to adopt cleaning strategy 2 to clean the oral area as the target area.

[0184] It is understood that the target cleaning strategy includes, but is not limited to, at least one of the cleaning mode, cleaning action, cleaning time, cleaning amplitude, cleaning swing angle, and cleaning pressure corresponding to the oral cleaning device 100 for cleaning the target area. Different cleaning modes may correspond to different at least one of the cleaning time, cleaning amplitude, cleaning swing angle, cleaning frequency, and cleaning pressure.

[0185] In some embodiments, the target cleaning strategy includes at least a target cleaning time corresponding to the target area. When controlling the oral cleaning device 100 to clean the target area in the user's oral cavity using the target cleaning strategy, the controller is further configured to:

[0186] Calculating the cleaning time corresponding to the oral cleaning device 100 performing the cleaning operation in the current target area using the target cleaning strategy;

[0187] When the cleaning time is greater than or equal to the target cleaning time, the oral cleaning device 100 and / or the terminal device connected to the oral cleaning device 100 for communication outputs a first prompt, wherein the first prompt is used to prompt the user to switch the target area for cleaning or to prompt the user that the current cleaning time of the target area is too long.

[0188] Exemplarily, a timer is provided in the oral cleaning device 100, and the timer is used to calculate the cleaning time t1 corresponding to the cleaning operation performed by the oral cleaning device 100 in the current target area using the target cleaning strategy. When the cleaning time t1 is greater than or equal to the target cleaning time T, it indicates that the oral cleaning device 100 can basically achieve the preset cleaning effect by using the target cleaning strategy to clean the target area, and the oral area can be changed for cleaning. Alternatively, the cleaning time of the current target area is too long, which may cause damage to the oral area to be cleaned or currently cleaned (e.g., causing wear of target objects such as teeth and gums in the oral area). At this time, the oral cleaning device 100 is controlled and / or a command is sent to the terminal device 200 that is communicatively connected to the oral cleaning device 100, so as to output a first prompt corresponding to the terminal device 200. Optionally, the first prompt includes but is not limited to at least one of a voice prompt, a vibration prompt, a graphic display, and a text display. For example, the first prompt is that the oral cleaning device 100 vibrates and emits a first prompt sound.

[0189] In some embodiments, the target cleaning strategy includes at least a target cleaning time corresponding to the target area. When controlling the oral cleaning device 100 to clean the target area in the user's oral cavity using the target cleaning strategy, the controller is further configured to:

[0190] When the cleaning time is less than the target cleaning time and the oral cleaning device 100 cleans another target area in the user's mouth that is different from the target area, the oral cleaning device 100 and / or the terminal device 200 communicatively connected to the oral cleaning device 100 is controlled to output a second prompt.

[0191] For example, when the cleaning time t1 is less than the target cleaning time T, and the oral cleaning device 100 switches to a different target area for cleaning, which may result in poor cleaning results for the current target area, the oral cleaning device 100 and / or the terminal device 200 communicatively connected to the oral cleaning device 100 is controlled to output a corresponding second prompt, which includes but is not limited to at least one of a voice prompt, a vibration prompt, a graphic display, and a text display. For example, the second prompt is the oral cleaning device 100 vibrating and emitting a second prompt sound.

[0192] In some embodiments, the target cleaning strategy includes at least a target cleaning action corresponding to cleaning the target area. When controlling the oral cleaning device 100 to clean the target area in the user's oral cavity using the target cleaning strategy, the controller is further configured to:

[0193] Acquiring second posture information of the oral cleaning device 100 collected by the posture sensor;

[0194] determining, based on the second posture information, whether a cleaning action corresponding to the cleaning of the target area by the oral cleaning device 100 matches the target cleaning action;

[0195] When the cleaning action corresponding to the cleaning of the target area by the oral cleaning device 100 does not match the target cleaning action, the oral cleaning device 100 and / or the terminal device communicatively connected to the oral cleaning device 100 is controlled to output a third prompt.

[0196] Exemplarily, the oral cleaning device 100 stores action information of a standard cleaning action corresponding to a target area. When the oral cleaning device 100 adopts a target cleaning strategy to clean the target area in the user's mouth, the oral cleaning device 100 can collect the current second posture information of the oral cleaning device 100 through the posture sensor 30, so as to analyze the cleaning action corresponding to the current oral cleaning device 100 cleaning the target area based on the second posture information, and determine whether the cleaning action corresponding to the oral cleaning device 100 cleaning the target area matches the target cleaning action, such as whether at least one of the action amplitude and action frequency of the cleaning action is within the preset action range, and then analyze whether the current cleaning action meets the standard.

[0197] When the cleaning action corresponding to the oral cleaning device 100 for cleaning the target area does not match the target cleaning action, it may cause poor cleaning effect of the target area, or even cause the target area to be damaged. If the cleaning action is not standard, it may cause poor cleaning effect, or even cause wear of the cleaned object (such as teeth and gums). Therefore, when the cleaning action is not standard, the oral cleaning device 100 or the terminal device 200 outputs a corresponding prompt to prompt the user to adjust the cleaning action in time.

[0198] In some embodiments, the target cleaning strategy includes at least a target cleaning action corresponding to cleaning the target area. When controlling the oral cleaning device 100 to clean the target area in the user's oral cavity using the target cleaning strategy, the controller is further configured to:

[0199] Acquire second posture information of the oral cleaning device 100 collected by the posture sensor and second relative position information between the oral cleaning device 100 and the target part of the user collected by the distance sensor;

[0200] determining, based on the second posture information and the second relative position information, whether a cleaning action corresponding to the cleaning of the target area by the oral cleaning device 100 matches the target cleaning action;

[0201] When the cleaning action corresponding to the cleaning of the target area by the oral cleaning device 100 does not match the target cleaning action, the oral cleaning device 100 and / or the terminal device communicatively connected to the oral cleaning device 100 is controlled to output a third prompt.

[0202] Different from the aforementioned embodiment, in this embodiment, during the process of the oral cleaning device cleaning the target area of the oral cavity, the posture information of the oral cleaning device 100 collected by the posture sensor 30 and the relative position information collected by the distance sensor 40 are obtained, and the posture information and relative position information are used to comprehensively judge whether the cleaning action corresponding to the current user operating the oral cleaning device to clean the target area is standard. If the cleaning action is not standard, it may cause poor cleaning effect and even cause wear of the cleaned object (such as teeth and gums). Therefore, when the cleaning action is not standard, the oral cleaning device or terminal device outputs a corresponding prompt to prompt the user to adjust the cleaning action in time.

[0203] In some embodiments, the oral cleaning device 100 further includes a pressure sensor in communication with the controller, and the target cleaning strategy includes at least a target cleaning pressure corresponding to cleaning the target area. When controlling the oral cleaning device 100 to clean the target area in the user's oral cavity using the target cleaning strategy, the controller 70 is further configured to:

[0204] Acquiring pressure sensing information output by the pressure sensor;

[0205] determining, based on the pressure sensing information, whether the cleaning pressure corresponding to the cleaning of the target area by the oral cleaning device 100 matches the target cleaning pressure;

[0206] When the cleaning pressure corresponding to the cleaning of the target area by the oral cleaning device 100 does not match the target cleaning pressure, the oral cleaning device 100 and / or the terminal device in communication with the oral cleaning device 100 is controlled to output a fourth prompt.

[0207] In this embodiment, a pressure sensor 60 is provided on the oral cleaning device 100. During the process of the oral cleaning device 100 cleaning the target area of the oral cavity, the cleaning pressure of the user operating the oral cleaning device 100 to clean the target area in the oral cavity is obtained through the pressure sensor 60, and when the cleaning pressure is too large or too small, a corresponding prompt is output through the oral cleaning device 100 or the terminal device 200, so that the user can adjust the cleaning pressure in time to reduce the adverse effects of poor cleaning effect due to too low cleaning pressure or reduce the adverse effects of wear on the cleaned object (such as teeth and gums) caused by too high cleaning pressure.

[0208] In some embodiments, the controller 70 is also used to: obtain cleaning progress information of the oral cleaning device 100 cleaning each target area in the user's mouth; and control the oral cleaning device 100 to output a cleaning progress prompt of the user's oral cleaning and / or the target area currently being cleaned in the user's mouth based on the cleaning progress information.

[0209] Alternatively, the controller 70 is also used to: obtain cleaning progress information of the oral cleaning device 100 cleaning each target area in the user's mouth; and control the terminal device communicating with the oral cleaning device 100 to output a cleaning progress prompt of the user's oral cleaning, the target area currently being cleaned in the user's mouth, at least one of the target area that has been cleaned, or the target area that has not been cleaned according to the cleaning progress information.

[0210] Optionally, the oral cleaning device 100 is provided with a display component 50, and the controller 70 controls the oral cleaning device 100 to output a cleaning progress prompt of the user's oral cleaning according to the cleaning progress information, including:

[0211] According to the cleaning progress information, the display component 50 of the oral cleaning device 100 is controlled to display the cleaning progress prompt of the user's oral cleaning and update the cleaning progress prompt, wherein the cleaning progress prompt includes at least one of the cleaning progress percentage, cleaning progress bar, cleaning progress ring, and cleaning progress text information.

[0212] Optionally, the updating method of the cleaning progress prompt includes but is not limited to real-time updating based on the collected data, periodic updating, or updating after completing at least one of the target areas, which is not limited here.

[0213] Optionally, the oral cleaning device 100 is provided with a display component 50, and the controller 70 controls the oral cleaning device 100 to output the target area currently being cleaned in the user's oral cavity according to the cleaning progress information, including:

[0214] The display component 50 of the oral cleaning device 100 is controlled to display the target object model of the user's mouth according to the cleaning progress information, and highlight the target area currently being cleaned, wherein the target object model includes multiple target areas, and the target area currently being cleaned can be updated and displayed according to the cleaning progress information.

[0215] Optionally, the target object may be a tooth, and the target object model is a model of the tooth.

[0216] Optionally, the updating method of the target area currently being cleaned includes but is not limited to real-time updating according to collected data, periodic updating, or updating after cleaning of at least one target area is completed, which is not limited here.

[0217] Exemplarily, the sensing data of at least one sensor obtained by the sensing component provided in the oral cleaning device 100 (e.g., the sensing component includes but is not limited to at least one of the posture sensor 30, the distance sensor 40, the timer, and the pressure sensor 60) can be used to analyze the cleaning progress of the oral cleaning device 100 on each oral area in the user's mouth, thereby obtaining the corresponding cleaning progress information. For example, if it takes T time to clean the target area A, then the timing data of the timer can be used to analyze whether the corresponding target area A has been cleaned. Alternatively, if the cleaning pressure corresponding to the cleaning of the target area A is F, then the sensing data output by the pressure sensor 60 can be used to analyze whether the corresponding target area has been cleaned. Alternatively, if the target area A performs the cleaning action B corresponding to the cleaning, then the sensing data corresponding to the posture sensor 30 can be used to analyze whether the corresponding target area has been cleaned.

[0218] After obtaining the current oral cleaning progress information by analyzing the sensor data, the oral cleaning device 100 or the terminal device 200 communicating with the oral cleaning device 100 can be controlled according to the obtained cleaning progress information to output a cleaning progress prompt for the user's oral cleaning, the target area currently being cleaned in the user's mouth, the target area that has been cleaned, or the target area that has not been cleaned.

[0219] like Figure 4 As shown, for example, 12 of the current 16 areas of the oral cavity have been cleaned, then the control display component 50 and / or the terminal device 200 displays the corresponding cleaning progress as 75%, or displays that the cleaning of the 12 target areas has been completed, or displays that the cleaning of the 12 target areas has been completed, or displays that the cleaning of the 4 target areas has not yet been completed.

[0220] At the same time, the information displayed by the display component 50 or the terminal device 200 can be updated according to the cleaning progress corresponding to the oral cleaning performed by the oral cleaning device 100, for example, the display component 50 and / or the terminal device 200 displays the corresponding cleaning progress as 93%, or displays that 15 target areas have been cleaned.

[0221] In this embodiment, during the process of the oral cleaning device 100 cleaning the target area of the oral cavity, the cleaning progress information of the oral cleaning device 100 cleaning each target area in the oral cavity is obtained, and the corresponding cleaning progress prompt and at least one of the target areas currently being cleaned are output through the oral cleaning device 100 and / or the terminal device 200 communicatively connected to the oral cleaning device 100, so that the user can promptly know the current cleaning progress or the target area currently being cleaned through the cleaning progress prompt.

[0222] In some embodiments, after the oral cleaning device 100 completes cleaning of each target area in the user's mouth, the controller is also used to: control the oral cleaning device 100 to stop working; or, control the oral cleaning device 100 to stop working and output a fifth prompt and / or control the terminal device that is communicatively connected to the oral cleaning device 100 to output a fifth prompt.

[0223] In this embodiment, after the oral cleaning device 100 completes cleaning of all target areas in the oral cavity, the oral cleaning device 100 is automatically controlled to stop operating. Alternatively, the oral cleaning device 100 is controlled to output the fifth prompt and / or the terminal device connected to the oral cleaning device 100 is controlled to output the corresponding prompt, which can effectively improve the user's oral cleaning experience.

[0224] In some embodiments, after the oral cleaning device 100 completes cleaning of each target area in the user's oral cavity, the controller 70 is further configured to:

[0225] Obtaining a region cleaning score corresponding to cleaning each target region in the user's oral cavity using the target cleaning strategy matching the target region;

[0226] The cleaning score of the oral cleaning process is calculated according to the regional cleaning score corresponding to each target area.

[0227] Optionally, the controller 70 obtains the area cleaning score corresponding to each target area in the user's oral cavity being cleaned using the target cleaning strategy matching the target area, including:

[0228] Calculating a deviation value between a corresponding cleaning action and a target cleaning action during a cleaning process in which each target area is cleaned using the target cleaning strategy matching the target area;

[0229] A region cleaning score corresponding to the target region is determined according to the deviation value.

[0230] Optionally, the controller 70 obtains the area cleaning score corresponding to each target area in the user's oral cavity being cleaned using the target cleaning strategy matching the target area, including:

[0231] Calculating a deviation between a cleaning time corresponding to a cleaning process in which each target area is cleaned using the target cleaning strategy matching the target area and a target cleaning time;

[0232] A region cleaning score corresponding to the target region is determined according to the deviation value.

[0233] Optionally, the controller 70 obtains the area cleaning score corresponding to each target area in the user's oral cavity being cleaned using the target cleaning strategy matching the target area, including:

[0234] Calculating a deviation between a cleaning pressure corresponding to each target area during a cleaning process using the target cleaning strategy matching the target area and a target cleaning pressure;

[0235] A region cleaning score corresponding to the target region is determined according to the deviation value.

[0236] Optionally, the controller 70 obtains the area cleaning score corresponding to each target area in the user's oral cavity being cleaned using the target cleaning strategy matching the target area, including:

[0237] Calculating a first deviation value between a cleaning time corresponding to a cleaning process in which each target area is cleaned using the target cleaning strategy matching the target area and a target cleaning time;

[0238] Calculating a second deviation value between a corresponding cleaning action and a target cleaning action during a cleaning process in which each target area is cleaned using the target cleaning strategy matching the target area;

[0239] A region cleaning score corresponding to the target region is determined according to the first deviation value and the second deviation value.

[0240] Exemplarily, the oral cleaning device 100 stores the association between the sensor data and deviation values collected by the corresponding sensor components (e.g., the sensor components include but are not limited to at least one of the posture sensor 30, the distance sensor 40, the timer, and the pressure sensor 60), or a sensor data analysis program or application. During the process of the oral cleaning device 100 cleaning the target area in the oral cavity, the deviation value corresponding to the sensor data can be obtained by obtaining the sensor data collected by at least one sensor component, so that the regional cleaning score of each target area can be obtained according to the deviation value and a preset score calculation function. Therefore, the cleaning score of the oral cleaning process of the user controlling the oral cleaning device 100 to clean the oral cavity can be obtained according to the cleaning score corresponding to each target area using the preset calculation function.

[0241] It is understandable that the specific reference sensor data basis for the cleaning score and the clean area score can be set as needed, and those skilled in the art can make adaptive adjustments as needed.

[0242] In some embodiments, after the oral cleaning device 100 completes cleaning of each target area in the user's oral cavity, the controller 70 is further configured to:

[0243] Obtaining cleaning results corresponding to cleaning of each target area in the user's oral cavity using the target cleaning strategy that matches the target area;

[0244] Determining whether the cleaning state of the corresponding target area is abnormal according to the cleaning result corresponding to the target area;

[0245] The terminal device 200 that is in communication with the oral cleaning apparatus 100 is controlled to display that the cleaning state corresponding to the target area is abnormal.

[0246] Optionally, the cleaning results include but are not limited to at least one of the following during the cleaning process of the target area: insufficient cleaning time for the target area, too long cleaning time for the target area, non-standard cleaning action for the target area, too high cleaning pressure for the target area, and too long cleaning pressure for the target area.

[0247] Optionally, the controller controls a terminal device in communication with the oral cleaning device 100 to display that the cleaning state corresponding to the target area is abnormal, including:

[0248] The terminal device in communication with the oral cleaning apparatus 100 is controlled to display a target object model in the user's oral cavity, wherein the target object model includes a plurality of target areas and highlights the target area with abnormal cleaning status.

[0249] Optionally, the method of highlighting the target area with abnormal cleaning status includes one of the following:

[0250] marking target areas with abnormal cleaning status in the target object model;

[0251] In the target object model, a first color is used to display a target area with an abnormal cleaning state, and a second color is used to display a target area with a normal cleaning state. The first color and the second color are not used.

[0252] Exemplarily, the oral cleaning device 100 stores a sensor data analysis program or application, or stores an association between sensor data collected by a corresponding sensor component (e.g., a sensor component including but not limited to at least one of a posture sensor 30, a distance sensor 40, a timer, and a pressure sensor 60) and a cleaning result. During the cleaning process of each target area in the oral cavity by the oral cleaning device 100, the sensor data collected by at least one sensor component is obtained, and the cleaning result of the corresponding target area can be obtained by analyzing the sensor data. The cleaning result is used to characterize whether there is an abnormality in the cleaning process of the target area by the oral cleaning device 100. For example, the cleaning result includes but is not limited to at least one of insufficient cleaning time of the target area, excessive cleaning time of the target area, non-standard cleaning action of the target area, excessive cleaning pressure of the target area, and excessive cleaning pressure of the target area during the cleaning process of the target area. After determining that the cleaning state of the corresponding target area is abnormal according to the cleaning result corresponding to the target area, the terminal device 200 connected to the oral cleaning device 100 is controlled to display the abnormal cleaning state of the target area.

[0253] For example, after the oral cleaning device 100 completes the cleaning of 16 oral areas, it is found that the cleaning time corresponding to the two target areas, "the anterior buccal surface of the maxillary bone" and "the anterior lingual surface of the maxillary bone", is insufficient. Then, the display component 50 of the oral cleaning device 100 is controlled, or the target object model (such as a tooth model) in the user's mouth is displayed through the terminal device 200 that is connected to the oral cleaning device 100 for communication. The target object model includes multiple target areas, and the target areas with abnormal cleaning status are highlighted through text annotation, color differentiation, etc., so that the user can intuitively know the target areas with abnormal cleaning status and perform corresponding remedial measures.
