[0002] At present, oral care devices, such as electric toothbrushes, have been increasingly widely used. An electric toothbrush drives a brush head connected with a motor to produce high-frequency vibration through rapid rotation or vibration of the motor, so as to instantaneously decompose toothpaste into fine foam and thus clean the surface of teeth and tooth gaps. The current electric toothbrush is usually provided with a detection module. However, the current energy receiving module only detects the health status of teeth in the oral cavity, and cannot provide comprehensive oral status analysis for users. UTILITARIAN CONTENT

[0004] The oral care device provided by the present application includes a handle and a detection module, the detection module is installed on the handle, the detection module includes an energy receiving module, the energy receiving module is movable relative to the handle to switch between a first position and a second position. When the energy receiving module is in the first position, the detection module is used for external oral detection; when the energy receiving module is in the second position, the detection module is used for internal oral detection.

[0005] The energy receiving module of the oral care device of the present application can move relative to the handle to switch between the first position and the second position. When the energy receiving module is in the first position, the detection module is used for external oral detection, and the energy receiving module can at least acquire at least part of energy reflected by human features outside the oral cavity. When the energy receiving module is in the second position, the detection module is used for internal and external oral detection, and the energy receiving module can at least acquire at least part of energy reflected by human features inside the oral cavity. Thus, the oral care device can comprehensively acquire detection results inside and outside the oral cavity of the human body, and provide more comprehensive oral status analysis for users.

The energy receiving module is used for receiving light energy or acquiring images, the internal oral detection includes acquiring tooth features and gum features inside the oral cavity, and the external oral detection includes acquiring facial features and / or acquiring features of the cleaning member connected to the handle.

[0007] In the intra-oral detection, the detection module extracts tooth features and gum features from the reflected light energy or the acquired image, and determines the oral cavity state according to the tooth features and the gum features; in the extra-oral detection, the detection module extracts facial features and cleaning piece features from the reflected light energy or the acquired image, and determines the relative position between the cleaning piece and the oral cavity according to the cleaning piece features and the facial features, thereby identifying the tooth area being brushed by the user.

[0008] In some embodiments, the intra-oral detection includes detecting at least one of a tooth cleaning condition, a tooth health condition, or a tooth arrangement condition.

[0027] In some embodiments, when the energy receiving module is in the first position and the energy receiving module captures that the cleaning tool is connected to the output shaft, the energy receiving module does not move relative to the handle. When the energy receiving module is in the first position and the energy receiving module captures that the cleaning tool is not connected to the output shaft, the energy receiving module extends relative to the handle to be in the second position.

[0028] When the energy receiving module is in the first position and the energy receiving module captures that the cleaning piece is connected to the output shaft, the energy receiving module does not move relative to the handle, which can avoid the user being poked by the movement of the energy receiving module when the user is in the care state; when the energy receiving module is in the first position and the energy receiving module captures that the cleaning piece is not connected to the output shaft, the energy receiving module extends relative to the handle to be in the second position, which can automatically adjust the position of the energy receiving module after the user finishes the care state to remind the user to perform the intraoral detection.

[0055] Retracting the energy receiving module into the handle can avoid the energy receiving module from shielding or interfering with the cleaning piece when the cleaning piece is used for oral cavity cleaning, and can also avoid foam and liquid from adhering to the energy receiving module during cleaning, thereby avoiding affecting the work of the energy receiving module.

[0056] In some embodiments, the energy receiving module is a zoom camera.

[0077] Referring to any one of the drawings, Figure 1 , and Figures 2 to 7 The oral care device 100 provided by embodiments of the present application includes a handle 10 and a detection module 20, the detection module 20 is installed on the handle 10, and the detection module 20 includes an energy receiving module 21, the energy receiving module 21 is movable relative to the handle 10 to switch between a first position and a second position. When the energy receiving module 21 is in the first position, the detection module 20 is used for extra-oral detection; when the energy receiving module 21 is in the second position, the detection module 20 is used for intra-oral detection.

[0078] Specifically, the oral care device 100 is a device capable of cleaning the oral cavity or detecting human features inside and outside the oral cavity, and the types of the oral care device 100 include but are not limited to an electric toothbrush, an oral scanning device, an endoscope or a water pick, etc. In the case where the oral care device 100 is an electric toothbrush or a water pick, the oral care device 100 can clean and detect the oral cavity. The oral care device 100 can use the energy receiving module 21 to locate the tooth area being brushed, so as to facilitate detection of the tooth area being brushed; or the oral care device 100 can also use the energy receiving module 21 to obtain an image of the tooth area after brushing, so as to facilitate the user to view the specific condition of the teeth, thereby detecting the brushing effect.

[0079] The handle 10 is a structure for the user to hold. The surface of the handle 10 can be provided with functional modules such as control areas and displays, so as to facilitate the user to operate and use various functions of the oral care device 100. The handle 10 is usually a cylindrical structure, so that the user has a comfortable holding feeling. The handle 10 can also have an anti-slip structure to avoid the oral care device 100 from slipping off the hand during use.

[0080] The energy receiving module 21 is configured to receive at least part of the energy reflected by the oral care device 100 and / or the human body feature. The energy receiving module 21 is movable relative to the handle 10 to switch between a first position and a second position, i.e. the relative position of the energy receiving module 21 and the handle 10 can be changed so as to receive energy reflected from different positions. Taking the oral care device 100 as an example of an electric toothbrush, when the user is brushing the teeth, the energy receiving module 21 is outside the oral cavity and is in the first position, and the energy receiving module 21 can receive at least part of the energy reflected by the human body feature outside the oral cavity and / or at least part of the energy reflected by the part elements (e.g. the cleaning element 30) of the oral scanning device, and the detection module 20 can perform an out-of-mouth detection based on the part of the energy reflected back to the energy receiving module 21 to locate the tooth area being brushed. When the user is not brushing the teeth, the energy receiving module 21 is inside the oral cavity and is in the second position, and the energy receiving module 21 can receive at least part of the energy reflected by the human body feature inside the oral cavity, and thus the detection module 20 can perform an in-oral detection based on the part of the energy reflected back to determine the state of the oral cavity after the user brushes the teeth.

[0081] In one example, the energy receiving module 21 can be a two-dimensional energy receiving module 21. In this case, the two-dimensional energy receiving module 21 comprises a lens and an image sensor, the lens collects light (light from the part to be scanned) in a field of view and transmits the light to the image sensor, the image sensor converts the light signal into an electrical signal and performs a series of conversions to finally form a two-dimensional image, so that the oral care device 100 can analyze data based on the two-dimensional image, and the user can view the two-dimensional image to obtain oral information, so that the user can locate the tooth area or obtain the result of the oral cavity after brushing the teeth based on the two-dimensional image. For example, the energy receiving module 21 can be a two-dimensional infrared camera module, in which the energy emitting module 23 in the detection module 20 emits infrared light, the infrared light emitted by the energy emitting module 23 irradiates the part to be scanned, and the part inside the oral cavity reflects part of the infrared light, the infrared camera module captures the reflected infrared light and converts it into a digital signal, and the digital signal is processed by a computer to generate an infrared image. For another example, the energy receiving module 21 can be a two-dimensional ultraviolet camera module, in which the energy emitting module 23 is configured to emit ultraviolet light, the ultraviolet light emitted by the energy emitting module 23 irradiates the part to be scanned, and the part inside the oral cavity reflects part of the ultraviolet light, the infrared camera module captures the reflected ultraviolet light and converts it into a digital signal, and the digital signal is processed by a computer to generate an ultraviolet image.

[0082] In another example, the energy receiving module 21 can be a time-of-flight camera. The time-of-flight camera first emits a laser pulse to the site to be scanned, and the laser pulse reaches the object to be photographed and is reflected back. The time-of-flight camera can calculate the distance from the site to be scanned to the time-of-flight camera by the time of the pulse emission and the time of the reflection back, so as to form a three-dimensional image, so that the oral care device 100 can analyze the data according to the three-dimensional image, and the user can view the three-dimensional image to obtain oral information, so that the user can perform tooth area positioning or obtain the oral result after brushing according to the three-dimensional image.

[0083] The energy receiving module 21 of the oral care device 100 of the embodiments of the present application can move relative to the handle 10 to switch between the first position and the second position. When the energy receiving module 21 is in the first position, the detection module 20 is used for extra-oral detection, and the energy receiving module 21 can at least acquire at least part of the energy reflected by the human body features outside the oral cavity. When the energy receiving module 21 is in the second position, the detection module 20 is used for intra- and extra-oral detection, and the energy receiving module 21 can at least acquire at least part of the energy reflected by the human body features inside the oral cavity. Thus, the oral care device 100 can comprehensively acquire the detection results of the human body inside and outside the oral cavity, and provide the user with a more comprehensive oral condition analysis.

[0084] Please refer to Figure 1 , and Figures 2 to 7 Any one of the figures, in some embodiments, the oral care device 100 further comprises a cleaning member 30 for cleaning the oral cavity. The energy receiving module 21 is used for receiving light energy or acquiring images, the intra-oral detection includes acquiring tooth features and gum features, and the extra-oral detection includes acquiring facial features and / or acquiring features of the cleaning member 30 connected to the handle 10.

[0085] Specifically, the cleaning member 30 is a structure detachably mounted to the handle 10. In the case of the oral care device 100 being an electric toothbrush, the cleaning member 30 can be a brush head 31. In the case of the oral care device 100 being a waterpik, the cleaning member 30 can be a nozzle of the waterpik for spraying liquid or foam outward. Taking the electric toothbrush as an example, the brush head 31 is a structure detachably mounted to the handle 10, so that the user can replace the brush head 31. The brush head 31 includes bristles and a brush handle 33, and the user can use the bristles to brush the teeth. The material of the bristles can be, but is not limited to, nylon, rubber, or pig bristles, etc. Preferably, the bristles can have good toughness and elasticity, so as to better clean the teeth and the interdental spaces. One end of the brush handle 33 is provided with the bristles, and the other end is connected to the handle 10.

[0086] In the case that the user is in the state of brushing teeth, the detection module 20 is used for extra-oral detection, the cleaning member 30 and the energy receiving module 21 are both mounted on the handle 10, at this time the cleaning member 30 extends into the inside of the oral cavity, the energy receiving module 21 is located outside the oral cavity, the energy receiving module 21 can move along with the handle 10 in the process of brushing teeth to change the relative position with the human body, and receive the energy reflected back by the cleaning member 30 and the human face or obtain the image of the cleaning member 30 and the human face, the detection module 20 extracts the facial features and the cleaning member 30 features according to the reflected energy or image and a certain algorithm, and judges the relative position of the cleaning member 30 and the oral cavity according to the cleaning member 30 features and the facial features, thereby identifying the tooth area that the user is brushing. The facial features of the human body include but are not limited to the left eye position, the right eye position, the nose position and the lip contour of the human body, and the cleaning member 30 features include but are not limited to the bristle position of the brush head 31 and the brush handle 33 position.

[0087] In the case that the user is not in the state of brushing teeth (for example, after brushing teeth), the detection module 20 is used for intra-oral detection, the cleaning member 30 is pulled out and no longer mounted on the handle 10, and the energy receiving module 21 is mounted on the handle 10, at this time the energy receiving module 21 extends into the inside of the oral cavity and can move along with the handle 10 inside the oral cavity to change the relative position with the teeth, and receive the energy reflected back by the inside of the oral cavity or the image, the detection module 20 extracts the tooth features and the gum features inside the oral cavity according to the reflected energy or image and a certain algorithm, and judges the oral cavity state according to the tooth features and the gum features.

[0088] Please refer to Figure 1 , and Figures 2 to 7 Any one figure, in some embodiments, the intra-oral detection includes detecting at least one of the tooth cleaning condition, the tooth health condition, or the tooth arrangement condition.

[0089] In particular, in the case that the energy receiving module 21 is located inside the oral cavity and the detection module 20 performs intraoral detection, the energy receiving module 21 obtains at least part of the energy reflected by the human features inside the oral cavity or obtains images inside the oral cavity, and the detection module 20 can identify dental plaque according to the reflected energy or images, thereby judging the tooth cleaning condition. For example, if the images show that the number of dental plaque after brushing is not lower than the expected number of dental plaque, it indicates that the tooth cleaning condition is not good. The detection module 20 can also identify dental caries and calculus according to the reflected energy or images, thereby judging the tooth health condition. For example, if the detection module 20 judges that the user has dental caries and calculus, it indicates that the tooth health condition is not good, and the oral scanning device can remind the user of the dental caries and calculus and suggest going to the doctor, etc. The detection module 20 can also identify tooth malformation and missing teeth according to the reflected energy or images, thereby judging the tooth arrangement condition. For example, if the detection module 20 judges that the user has tooth malformation and / or missing teeth, it indicates that the tooth arrangement condition is not good. Further, the oral scanning device can formulate and optimize the user's brushing strategy according to the results of intraoral detection (i.e., at least one of the tooth cleaning condition, the tooth health condition, or the tooth arrangement condition).

[0090] Referring to any one of Figure 1 , and Figures 2 to 7 In some embodiments, the extraoral detection includes detecting the position of oral care and / or detecting the entry condition of the cleaning member 30.

[0091] In particular, in the case that the cleaning member 30 is located inside the oral cavity and the energy receiving module 21 is located outside the oral cavity, the detection module 20 performs extraoral detection, and the detection module 20 can detect the position of oral care, i.e., the detection module 20 can locate the tooth area being brushed. For example, the position of the bristles in the cleaning member 30 can reflect the position of the tooth being brushed, and the detection module 20 can locate the tooth area being brushed and the tooth being brushed by the relative position of the bristles and the human features. Therefore, the energy receiving range of the energy receiving module 21 should at least cover the free end of the bristles to ensure that the energy receiving module 21 can receive information on both sides of the brush head 31, which is conducive to the oral care device 100 accurately locating the tooth being brushed. At the same time, when the energy receiving range covers the free end of the bristles, the energy receiving module 21 can also receive energy reflected by the tooth in contact with the free end of the bristles, so as to facilitate the oral care device 100 to obtain information of the tooth in contact with the free end of the bristles.

[0092] The detection module 20 can also detect whether the cleaning element 30 is in the mouth. For example, when the oral care device 100 is in the care state, the energy receiving module 21 can acquire an image containing the face of the human body and the cleaning element 30, and detect whether the cleaning element 30 is in the mouth according to the image. For example, the detection module 20 performs image recognition based on the image containing the face of the human body and the cleaning element 30. If the detection module 20 identifies that the image contains the brush head 31, it indicates that the cleaning element 30 is not in the mouth. If the detection module 20 identifies that the image does not contain the brush head 31, it indicates that the cleaning element 30 is in the mouth.

[0093] Referring to any one of Figure 1 , and Figures 2 to 7 In some embodiments, when the energy receiving module 21 is in the first position, the detection module 20 is used for extra-oral detection when the oral care device 100 is in the care state; and when the energy receiving module 21 is in the second position, the detection module 20 is used for intra-oral detection when the oral care device 100 is in the non-care state.

[0094] Specifically, in the embodiment in which the oral care device 100 is an electric toothbrush, the care state is a state in which the user brushes teeth, and the non-care state is a state in which the user does not brush teeth. Thus, the detection module 20 can perform extra-oral detection when the user brushes teeth, so as to locate the tooth area being brushed, and can perform intra-oral detection when the user does not brush teeth, so as to detect the state of the oral cavity after brushing teeth and determine whether the brushing strategy of the oral care device 100 is reasonable.

[0095] Referring to any one of Figure 1 , and Figures 2 to 7 In some embodiments, the oral care device 100 further comprises a driving element 40 for driving the cleaning element 30. When the energy receiving module 21 is in the first position, the driving element 40 can work, and when the energy receiving module 21 is in the second position, the driving element 40 cannot work.

[0096] Specifically, in the case in which the oral care device 100 is a water pick, the driving element 40 can be a pump for pumping liquid in the pump to a nozzle; in the case in which the oral care device 100 is an electric toothbrush, the driving element 40 can be a motor. When the driving element 40 is powered on and starts to work, the output shaft of the driving element 40 can drive the brush head 31 to vibrate to automatically clean the teeth.

[0097] When the energy receiving module 21 is in the first position, the cleaning element 30 is installed on the handle 10, and the driving element 40 can drive the cleaning element 30 to clean the oral cavity; when the energy receiving module 21 is in the second position, the cleaning element 30 is not installed on the handle 10, and the driving element 40 cannot work. Thus, the vibration generated when the driving element 40 works can be avoided, the energy receiving module 21 can work in a stable state, and the quality of the light energy and the image acquired by the energy receiving module 21 can be improved.

[0098] Please see Figure 1 ,and Figure 8 In any of the figures, in some embodiments, the cleaning component 30 is detachably connected to the handle 10. When the energy receiving module 21 is in the first position, the cleaning component 30 is connected to the handle 10, and when the energy receiving module 21 is in the second position, the cleaning component 30 is separated from the handle 10.

[0099] Specifically, the detachable connection between the cleaning element 30 and the handle 10 includes, but is not limited to, snap-fit ​​connections or bolt connections. In the first position, the energy receiving module 21 is connected to the handle 10, allowing it to acquire features of the cleaning element 30. In the second position, the cleaning element 30 is separated from the handle 10, preventing both from entering the oral cavity. This prevents the cleaning element 30 from occupying space and obstructing the energy receiving module 21 from acquiring light energy and images from the oral cavity, ensuring sufficient space for movement within the oral cavity. This also helps prevent the image acquired by the energy receiving module 21 from being obstructed by the cleaning element 30, improving the accuracy of intraoral detection.

[0100] Please see Figure 9 , Figure 1 and Figures 2 to 7 In some embodiments, the oral care device 100 controls its care operations based on the results of intraoral detection; when the oral care device 100 is in a care state, the oral care device 100 controls its care operations based on the results of extraoral detection.

[0101] Specifically, before the user brushes their teeth for the first time, the oral care device 100 sets default values ​​for the state parameters of each tooth area, assuming that the user's teeth condition conforms to the average condition. The default values ​​are calculated based on the average distribution of collected data. These default values ​​include at least the predicted amount of plaque on the tooth surface.

[0102] When the user brushes teeth for the first time, the oral care device 100 is in the care state, the detection module 20 performs the extra-oral detection, and the real-time display of the current tooth surface to be brushed is the predicted plaque amount, which is not the detection value. When the predicted plaque amount is reduced to meet the requirement of clean brushing, the user is prompted to switch the tooth surface. After the user completes the brushing, the oral care device 100 is in the non-care state, the detection module 20 performs the intra-oral detection, and the user uses the oral care device 100 to scan each tooth surface; the interactive device displays the plaque content, gum bleeding condition and caries condition of each tooth after brushing in real time. After the intra-oral detection, the interactive device graphically displays the scanning results (which can be in the form of a 3D tooth model, a schematic diagram, etc.), and gives brushing suggestions, such as: tooth A is relatively dirty, and more time should be spent on brushing next time; tooth B is relatively sensitive, and should be brushed more gently; tooth C has caries symptoms, and is suggested to go to a doctor for further diagnosis.

[0103] Further, the oral care device 100 updates the care strategy based on the results of the intra-oral detection, and the care strategy at least includes the recommended brushing time and the recommended brushing pressure of each tooth area. When brushing again, the oral care device 100 performs real-time extra-oral detection to real-time locate the tooth area being brushed, the oral care device 100 adjusts the recommended brushing time of the tooth area being brushed based on the updated care strategy, adjusts the overpressure threshold of the tooth area being brushed according to the recommended brushing pressure, and calculates the predicted plaque amount of each tooth surface of the tooth area being brushed in real time. When the predicted plaque amount is reduced to a preset amount, the user is prompted to switch the tooth surface or tooth area.

[0104] The care strategy can calculate the difference between the theoretical plaque residue and the actual situation under the current brushing behavior and the current oral contamination degree according to the actual situation of the plaque residue. The plaque amount is predicted from the last brushing, and the plaque amount before brushing is a function of the length of time from the last brushing, that is, B(t). The interval time of the first brushing is taken from the average time from the last brushing of the user. The brushing strategy is to recommend the user's use behavior to the toothbrush. The brushing strategy includes the recommended brushing time T=[t1, t2,...tn] and the recommended brushing pressure P=[p1, p2,...pn], wherein n is the tooth surface number, the recommended brushing time T is the time required to brush the tooth surface to the clean standard, and the brushing strategy is calculated according to the tooth plaque removal efficiency, that is, T=B⊙C -1 . The tooth plaque removal efficiency (the amount of tooth plaque removed per unit time during brushing) is a function of the brushing pressure and the brushing efficiency, that is, C(e ·p). The brushing efficiency e depends on the user's tooth surface characteristics and specific brushing habits, and needs to be learned and updated. If the relationship between the plaque removal efficiency and the brushing efficiency is a linear relationship, the plaque removal efficiency is eC(p). The recommended brushing pressure p is the pressure closest to the maximum cleaning force pressure that is lower than the sensitive pressure of the gingiva near the tooth surface. The sensitive pressure p is calculated according to the gingival bleeding and the gingival image. The user behavior is the real behavior of the user when using the toothbrush to brush, including the actual brushing time Tu and the actual brushing pressure Pu. The expected cleaning effect will be obtained according to the actual behavior of the user. The expected cleaning effect is E = B(t) - C⊙Tu. The actual cleaning effect E_u comes from the in-mouth detection result after brushing. According to the difference between the expected cleaning effect and the actual cleaning effect for multiple times or a single time, a loss function is constructed, and using any optimization algorithm can obtain the brushing efficiency e that makes the expected cleaning effect and the actual cleaning effect as close as possible (minimizes the loss function). According to the brushing efficiency e and the recommended brushing pressure P, the recommended brushing time (not considering whether the user obeys the recommended brushing time) T = B(t)⊙C(e · p) -1 . Wherein B(t) is the plaque amount before brushing, C is the plaque removal efficiency; e is the brushing efficiency; p is the brushing pressure. The brushing strategy needs to consider the difference between the user behavior and the recommended behavior, so that the user can passively try to approach the brushing strategy brushing.(If the user often brushes less than the recommended brushing time in some tooth areas, he needs to be allocated longer recommended time, including more frequent reminder of supplementary brushing, etc.). According to the difference between the user's actual brushing time and the recommended brushing time, a loss function is constructed, and using any optimization algorithm can obtain the compensation time that makes the user's actual brushing time and the recommended brushing time as close as possible. The final brushing strategy is equal to the sum of the recommended brushing time and the user habit compensation time. E is the expected cleaning effect, E = B(t) - C⊙Tu. Tu is the actual brushing time, and Pu is the actual brushing pressure.

[0105] Please refer to Figure 1 , and Figures 2 to 7 Any one figure, in some embodiments, the detection module 20 further comprises a first energy emitting module 231 and a second energy emitting module 232, the first energy emitting module 231 works when the energy receiving module 21 is in the first position, and the second energy emitting module 232 works when the energy receiving module 21 is in the second position.

[0106] Specifically, in some embodiments, the oral care device 100 further comprises an energy emitting module 23 for emitting energy, and the energy receiving module 21 for receiving at least part of the energy emitted by the energy emitting module 23 and reflected. The energy emitting module 23 can emit energy outward, and the energy form includes but is not limited to sound, light, electricity, etc. In this application, the energy emitting module 23 is used to emit light of different wave bands. The energy emitting module 23 can be opposite to the cleaning element 30, so that at least part of the energy emitted by the energy emitting module 23 can be reflected by the cleaning element 30, the human body outside or inside the oral cavity. The energy emitting module 23 can be one or more, and in this application, the energy emitting module 23 is two, which are the first energy emitting module 231 and the second energy emitting module 232.

[0107] The first energy emitting module 231 works when the energy receiving module 21 is in the first position, and the light emitted by the first energy emitting module 231 can enter the energy receiving module 21 after being reflected by the cleaning element 30 and the face of the human body. The reflected light carries the feature information of the cleaning element 30 and the face of the human body, and the detection module can extract the cleaning element 30 feature and the face feature according to the reflected light.

[0108] The second energy emitting module 232 works when the energy receiving module 21 is in the second position, and the light emitted by the second energy emitting module 232 can enter the energy receiving module 21 after being reflected by the inside of the oral cavity. The reflected light carries the feature information of the teeth and gums inside the oral cavity, and the detection module can extract the tooth feature and the gum feature according to the reflected light.

[0109] Please refer to Figure 1 , and Figures 2 to 7 any figure, in some embodiments, the energy receiving module 21 comprises an image sensor. The first energy emitting module 231 and / or the second energy emitting module 232 is a visible light source. The image sensor comprises visible light pixels, and the first energy emitting module 231 and / or the second energy emitting module 232 is a visible light source. The image sensor comprises infrared light pixels and near-infrared light pixels, and the first energy emitting module 231 and / or the second energy emitting module 232 is an infrared light source and / or a near-infrared light source. The image sensor comprises ultraviolet light pixels, and the first energy emitting module 231 and / or the second energy emitting module 232 is an ultraviolet light source.

[0110] Specifically, in the case that the detection module 20 performs extra-oral detection, in an embodiment, the first energy emitting module 231 and / or the second energy emitting module 232 is a visible light source, the image sensor includes visible light pixels, and the energy receiving module 21 is capable of acquiring a visible light image. In the case that the detection module 20 performs extra-oral detection, the visible light emitted by the visible light source can play a certain illuminating role on the user's face and the environment, so that the user can observe the user's facial condition against the mirror, and it is also beneficial for the energy receiving module 21 to acquire a visible light image under suitable brightness, so as to determine the relative position of the cleaning element 30 and the oral cavity, thereby facilitating the positioning of the tooth area being brushed; in the case that the detection module 20 performs intra-oral detection, the visible light can illuminate the oral cavity, thereby facilitating the energy receiving module 21 to collect images in the oral cavity.

[0111] In another embodiment, the first energy emitting module 231 and / or the second energy emitting module 232 is an infrared light source or a near-infrared light source, the image sensor includes infrared light pixels and near-infrared light pixels, and the energy receiving module 21 is capable of acquiring an infrared light image and / or a near-infrared image. In the case that the detection module 20 performs extra-oral detection, it is beneficial for the positioning of the tooth area being brushed; in the case that the detection module 20 performs intra-oral detection, the infrared light and / or the near-infrared light can detect early demineralization changes of the tooth enamel, thereby facilitating the detection of early dental caries.

[0112] In still another embodiment, the first energy emitting module 231 and / or the second energy emitting module 232 is an ultraviolet light source, the image sensor includes ultraviolet light pixels, and the energy receiving module 21 is capable of acquiring an ultraviolet light image. In the case that the detection module 20 performs extra-oral detection, the ultraviolet light can detect the state of the cleaning element 30, such as whether it is wet, whether it has toothpaste, whether it is correctly installed on the handle 10, etc., so as to ensure the correct use of the oral care device 100; in the case that the detection module 20 performs intra-oral detection, dental plaque can emit fluorescence under ultraviolet light, thereby the detection module 20 can detect the number of dental plaque of the teeth according to the ultraviolet light image.

[0113] Please refer to Figure 1 , and Figures 2 to 7 any one of the drawings, in some embodiments, the handle 10 includes a housing 11 and a core 13, the core 13 is installed in the housing 11, at least part of the output shaft of the core 13 extends out of the housing 11, and the output shaft is used to connect with the cleaning element 30 for cleaning the oral cavity; in the case that the energy receiving module 21 is in the second position, a preset distance is provided between the detection module 20 and the output shaft.

[0114] Specifically, the housing 11 has a cavity structure for accommodating other components. The material of the housing 11 includes, but is not limited to, plastic, silicone, or rubber. The mechanism 13 is disposed inside the housing 11, so that the housing 11 can ensure the aesthetics of the oral care device 100 while preventing external impurities, such as dust, from falling into the internal structure of the oral care device 100, thereby affecting the cleanliness of the internal structure of the oral care device 100.

[0115] The mechanism 13 is a structure used to drive the cleaning element 30 to operate. Taking an electric toothbrush as an example, when the cleaning element 30 is the brush head 31, the mechanism 13 is a structure used to drive the brush head 31 to vibrate. After the user activates the oral care device 100, the mechanism 13 begins to vibrate, and drives the brush head 31 to vibrate via the output shaft, thereby cleaning the teeth through the bristles of the vibrating brush head 31. When the energy receiving module 21 is in the second position, a preset distance is provided between the detection module 20 and the output shaft, which reduces the obstruction of the output shaft to energy reception, thereby ensuring that the energy receiving module 21 can acquire more effective information.

[0116] Please see Figure 1 ,and Figures 2 to 7 In any of the figures, in some embodiments, the detection module 20 further includes a sterilization module 25. The sterilization module 25 moves together with the energy receiving module 21 relative to the handle 10. When the energy receiving module 21 is in the first position and the cleaning component 30 is installed on the handle 10, the sterilization module 25 is used to sterilize the cleaning component 30.

[0117] Specifically, the sterilization module 25 can emit ultraviolet light, and the emitted ultraviolet light at least covers the end of the cleaning component 30 away from the handle 10 when the cleaning component 30 is installed on the handle 10, thereby the sterilization module 25 can sterilize the cleaning component 30.

[0118] Please see Figure 1 ,and Figures 2 to 5 In any of the figures, in some embodiments, when the energy receiving module 21 is in the first position and the energy receiving module 21 detects that the cleaning component 30 is connected to the output shaft, the energy receiving module 21 does not move relative to the handle 10. When the energy receiving module 21 is in the first position and the energy receiving module 21 detects that the cleaning component 30 is not connected to the output shaft, the energy receiving module 21 extends relative to the handle 10 to a second position.

[0119] Specifically, when the energy receiving module 21 is in the first position and the energy receiving module 21 captures that the cleaning member 30 is connected to the output shaft, the energy receiving module 21 does not move relative to the handle 10, which can avoid the user from being poked by the movement of the energy receiving module 21 when the user is in the care state (e.g., brushing teeth); when the energy receiving module 21 is in the first position and the energy receiving module 21 captures that the cleaning member 30 is not connected to the output shaft, the energy receiving module 21 extends relative to the handle 10 to be in the second position, which can automatically adjust the position of the energy receiving module 21 to remind the user to perform the in-mouth detection after the user ends the care state.

[0120] Referring to any one of Figure 1 , and Figures 2 to 5 In some embodiments, the oral care device 100 further comprises a driving assembly 50, the driving assembly 50 is connected to the handle 10, and the driving assembly 50 is configured to drive the energy receiving module 21 to move relative to the handle 10 to switch between the first position and the second position. Thus, the detection module 20 is facilitated to switch between the out-of-mouth detection and the in-mouth detection, and the switching efficiency is improved.

[0121] Referring to any one of Figure 1 , and Figure 2 In some embodiments, the driving assembly 50 comprises a trigger 51 and an actuator 53, the trigger 51 is installed on the handle 10 and exposed from the side wall of the handle 10. The actuator 53 is installed in the handle 10, the trigger 51 is communicatively connected to the actuator 53, the actuator 53 is connected to the energy receiving module 21, and the trigger 51 is configured to trigger the actuator 53 to start, and the actuator 53 is configured to drive the energy receiving module 21 to move relative to the handle 10 to switch between the first position and the second position.

[0122] Specifically, the trigger 51 and the actuator 53 can be wired or wireless. The trigger 51 includes but is not limited to a button and a touch screen, etc. The trigger 51 facilitates the user to control the energy receiving module 21 to move relative to the handle 10 to switch between the first position and the second position, thereby facilitating the detection module 20 to switch between the out-of-mouth detection and the in-mouth detection, and improving the switching efficiency.

[0123] Referring to any one of Figure 1 , and Figure 3 In some embodiments, the actuator 53 is a linear motor 531, and comprises a stator and a mover protruding from the stator, the energy receiving module 21 is connected to the mover, and the mover is configured to extend and retract relative to the stator to drive the energy receiving module 21 to move relative to the handle 10 and switch between the first position and the second position.

[0124] Specifically, taking the electric toothbrush as an example, when the oral care device 100 is in the care state, the user brushes teeth through the electric toothbrush, the energy receiving module 21 is located at the first position, at this time the energy receiving module 21 is at least partially accommodated in the handle 10. After the end of tooth brushing, the user triggers the actuating member 53 through the trigger 51 to start, the stator generates a magnetic field, the mover moves under the action of the magnetic field, thereby driving the energy receiving module 21 to move towards the direction of the second position, the energy receiving module 21 gradually extends from the handle 10, after the energy receiving module 21 moves to the second position, the mover stops moving, thereby locking the energy receiving module 21 at the second position, and the detection module can perform intraoral detection. After the end of intraoral detection, the user triggers the actuating member 53 through the trigger 51 to start, or the actuating member 53 is automatically started, the stator generates a magnetic field, the mover moves under the action of the magnetic field, thereby driving the energy receiving module 21 to move towards the direction of the first position, the energy receiving module 21 retracts into the handle 10, after the energy receiving module 21 moves to the first position, the mover stops moving, thereby locking the energy receiving module 21 at the first position, thereby completing the movement of the energy receiving module 21 relative to the handle 10 and switching between the first position and the second position.

[0125] Please refer to Figure 1 and Figure 4 In some other embodiments, the actuating member 53 is a screw rod motor 533, and includes a motor 5331 and a screw rod 5333, one end of the screw rod 5333 is connected with the motor 5331, the energy receiving module 21 is sleeved on the screw rod 5333, the motor 5331 is used to drive the screw rod 5333 to rotate, so as to drive the energy receiving module 21 to move along the screw rod 5333 and switch between the first position and the second position through the screw rod 5333.

[0126] Specifically, when the oral care device 100 is in the care state, the user brushes teeth by the electric toothbrush, the energy receiving module 21 is located in the first position, at this time the energy receiving module 21 is at least partially accommodated in the handle 10. After the end of tooth brushing, the user triggers the actuating member 53 by the trigger 51 to start, the motor 5331 drives the screw rod 5333 to rotate, the screw rod 5333 drives the energy receiving module 21 to move along the screw rod 5333 in the direction of the second position, the energy receiving module 21 gradually extends from the handle 10, after the energy receiving module 21 moves to the second position, the screw rod 5333 stops moving, thereby locking the energy receiving module 21 in the second position, the detection module can carry out the in-mouth detection. After the end of the in-mouth detection, the user triggers the actuating member 53 by the trigger 51 to start, or the actuating member 53 is automatically started, the motor 5331 drives the screw rod 5333 to rotate, the screw rod 5333 drives the energy receiving module 21 to move along the screw rod 5333 in the direction of the first position, the energy receiving module 21 retracts into the handle 10, after the energy receiving module 21 moves to the first position, the screw rod 5333 stops moving, thereby locking the energy receiving module 21 in the first position, thereby completing the movement of the energy receiving module 21 relative to the handle 10 and switching between the first position and the second position.

[0127] Please refer to Figure 1 and Figure 5 In still another embodiment, the driving assembly 50 further comprises a resilient member 55, one end of the resilient member 55 is connected with the motor 5331, the other end of the resilient member 55 is connected with the energy receiving module 21, in the process of the screw rod 5333 driving the energy receiving module 21 to move to the second position, the resilient member 55 is used to provide the energy receiving module 21 with the elastic force in the direction of the second position.

[0128] Specifically, the elastic member 55 includes but is not limited to a spring. When the oral care device 100 is in the care state, the user brushes teeth by the electric toothbrush, the energy receiving module 21 is located in the first position, at this time the energy receiving module 21 is at least partially accommodated in the handle 10, and the elastic member 55 is in the compressed state. After the end of tooth brushing, the user triggers the actuating member 53 by the trigger member 51 to start, and in the process of the elastic member 55 recovering from the compressed state to the free state, the elastic member 55 can provide the energy receiving module 21 with an elastic force in the direction of the second position, and the energy receiving module 21 gradually extends from the handle 10. After the energy receiving module 21 moves to the second position, the elastic member 55 stops moving, thereby locking the energy receiving module 21 in the second position, and the detection module can perform intraoral detection. After the end of intraoral detection, the user triggers the actuating member 53 by the trigger member 51 to start, or the actuating member 53 is automatically started, the motor 5331 drives the screw rod 5333 to rotate, the screw rod 5333 drives the energy receiving module 21 to move along the screw rod 5333 in the direction of the first position, and the energy receiving module 21 is retracted into the handle 10.

[0137] Referring to Figure 1 and Figure 7 In some embodiments, the oral care device 100 further comprises a sealing member 90, which is used to seal the gap between the handle 10 and the energy receiving module 21.

[0138] Specifically, the humidity of the use scene of the oral care device 100 is high, and long-time contact with liquid will affect the operation of the energy receiving module 21. There is a certain gap between the handle 10 and the energy receiving module 21, so there is a risk that liquid will enter the handle 10 through the gap between the handle 10 and the energy receiving module 21 and come into contact with the energy receiving module 21. The sealing member 90 is arranged in the gap between the handle 10 and the energy receiving module 21 to avoid the liquid entering the handle 10 through the gap between the handle 10 and the energy receiving module 21 and coming into contact with the energy receiving module 21, thereby ensuring the normal use of the oral care device 100. The material of the sealing member 90 includes but is not limited to rubber, plastic or silicone, etc.

[0141] Please see Figure 1 ,and Figures 2 to 7 In any of the figures, in some embodiments, at least a portion of the output shaft of the mechanism 13 extends from the housing 11, and the output shaft is used to connect to the cleaning component 30 for cleaning the oral cavity; when the energy receiving module 21 is in the second position, the energy receiving module 21 is higher than the output shaft; when the energy receiving module 21 is in the first position, the energy receiving module 21 is lower than the output shaft.

[0142] Specifically, when the energy receiving module 21 is in the second position, it is higher than the output shaft, which can prevent the output shaft from blocking or interfering with the energy receiving module 21 when it is performing intraoral detection; when the energy receiving module 21 is in the first position, it is lower than the output shaft, which can prevent the cleaning component 30 on the output shaft from blocking or interfering with the cleaning component 30 when it is performing oral cleaning.

[0143] Please see Figure 1 ,and Figures 2 to 7 In any of the figures, in some embodiments, the detection module 20 further includes a carrier 27. The energy receiving module 21 is mounted on the carrier 27. In the longitudinal direction of the handle 10, the length of the carrier 27 is greater than the length of the output shaft. The carrier 27 is mounted inside the handle 10 and can move relative to the handle 10 to extend or retract from the mounting space. When the carrier 27 is inside the handle 10, the energy receiving module 21 is in a first position. When the carrier 27 is fully extended from the handle 10, the energy receiving module 21 is in a second position.

[0144] Please see Figure 1 ,and Figures 2 to 7 In any of the figures, in some implementations, the energy receiving module 21 is a zoom camera.

[0145] Specifically, the energy receiving module 21 can switch between a first position and a second position. Correspondingly, the zoom camera can change its focal length in the first position and the second position. Thus, the energy receiving module 21 can obtain a clear image whether the detection is outside the mouth or inside the mouth.

[0146] Please see ​ ,and ​ In any of the figures, in some embodiments, the zoom camera includes a macro imaging mode, and the zoom camera also includes at least one of a normal imaging mode, a telephoto imaging mode, and a wide-angle imaging mode.

[0147] The macro imaging mode provides a very high magnification, and the energy receiving module 21 can capture images of close-range objects, which is conducive to subtle observation of the inside of the oral cavity, so that the energy receiving module 21 can detect the microstructure of the tooth surface; the telephoto mode can magnify distant objects, so that the energy receiving module 21 can capture images of the deep part of the oral cavity, such as the teeth and gums in the back part of the oral cavity; the wide-angle mode provides a wide field of view, and the energy receiving module 21 can capture more internal structures of the oral cavity at one time, which is conducive to obtaining information about the arrangement and occlusion of the dentition.
