DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] like Figure 1-4As shown, an embodiment of the present application provides an oral care device 100 , which includes a handle assembly 110 , a care piece 120 , and an energy receiving device 130 .

[0048] like Figure 3-4 As shown, the handle assembly 110 includes a handle 111 and a movement 112 .

[0049] The handle 111 can be used to accommodate the movement 112, and the handle 111 can be convenient for the user to hold. The handle 111 is formed with a mounting cavity 111a and a receiving port 111b connected to the mounting cavity 111a. The material of the handle 111 can be plastic, so that the handle 111 is light and the user can hold it with less effort. At the same time, the plastic handle 111 can be integrally formed, so it has a good waterproof effect and can also be formed into a complex shape.

[0050] The movement 112 includes an output shaft 1121, which is installed in the installation cavity 111a and extends out of the installation cavity 111a, that is, the output shaft 1121 of the movement 112 passes from the inside of the handle 111 to the outside of the handle 111 to connect with the care part 120.

[0051] The specific type of the care piece 120 is related to the type of the oral care device 100. The oral care device 100 can be illustratively an electric toothbrush, an oral irrigator, an oral detection device, etc. When the oral care device 100 is an electric toothbrush, the care piece 120 is a brush head. When the oral care device 100 is an oral irrigator, the care piece 120 is a nozzle. When the oral care device 100 is an oral detection device, the care piece 120 is an endoscope head. Exemplarily, the care piece 120 is a brush head, and the brush head is connected to one end of the output shaft 1121 extending out of the mounting cavity 111a. The output shaft 1121 of the movement 112 can generate high-frequency reciprocating vibrations, thereby driving the brush head to generate high-frequency reciprocating vibrations. When the brush head contacts the user's teeth, the high-frequency reciprocating vibrating brush head can peel off food residues on the user's teeth or tongue to achieve the purpose of cleaning the oral cavity. It can be understood that when the care part 120 is a nozzle, the output shaft 1121 can also be used to deliver high-pressure water flow. When the care part 120 is a nozzle endoscope head, the output shaft 1121 can also be used to conduct light. Different types of care parts 120 are combined with different movements 112 to achieve different functions.

[0052] The energy receiving device 130 is connected to the movement 112 or the handle 111, and the energy receiving device 130 only needs to be fixed. For example, the energy receiving device 130 is set on the handle 111, and the energy receiving device 130 and the movement 112 are set separately, or the energy receiving device 130 is set on the movement 112, and the energy receiving device 130 can be used as a part of the movement 112. The energy receiving device 130 and the movement 112 or the handle 111 can be connected by snapping, bonding, welding, etc. The energy receiving device 130 is set corresponding to the receiving port 111b, and external energy can enter the energy receiving device 130 through the receiving port 111b.

[0053] The receiving port 111b is formed on the outer surface of the handle 111. Optionally, the receiving port 111b is waterproofed to prevent water from entering the mounting cavity 111a of the handle 111 and affecting the normal operation of the electronic devices such as the movement 112 in the mounting cavity 111a. For example, the shape of the receiving port 111b is adapted to the shape of the energy receiving device 130, so that the energy receiving device 130 can block the receiving port 111b to seal the mounting cavity 111a. Alternatively, the connection between the energy receiving device 130 and the receiving port 111b is sealed to seal the mounting cavity 111a.

[0054] The energy receiving device 130 receives energy through the receiving port 111b, and the type of the receiving port 111b is related to the type of the energy receiving device 130. The energy receiving device 130 can be a camera, a photoelectric sensor, a sound wave sensor, or an infrared sensor. When the energy receiving device 130 is a camera, the receiving port 111b is used to transmit visible light, and the receiving port 111b can be set open or covered by a transparent cover. When the energy receiving device 130 is a photoelectric sensor, the receiving port 111b is used to transmit visible light or invisible light, and the receiving port 111b can be set open or covered by a transparent cover. When the energy receiving device 130 is an infrared sensor, the receiving port 111b is used to transmit infrared light (heat transfer), and the receiving port 111b can be set open or covered by a transparent cover. When the energy receiving device 130 is an sound wave sensor, the receiving port 111b is used to transmit sound waves, and the receiving port 111b needs to be set open to prevent the sound waves from being blocked.

[0055] In some cases, the receiving port 111b can be used to install the energy receiving device 130. After the energy receiving device 130 is assembled, a transparent cover is installed on the receiving port 111b to cover the receiving port 111b, thereby facilitating the assembly of the energy receiving device 130 and ensuring the sealing of the receiving port 111b.

[0056] like Figure 5As shown, the energy receiving device 130 is used to receive energy reflected from the user's face. The energy exemplarily includes visible light, invisible light (infrared light, etc.), sound waves, ultrasonic waves, etc. By receiving the energy reflected from the user's face, it is equivalent to receiving the user's body feature information. For example, by acquiring an optical image of the user's face, image information of the user's face can be acquired. By acquiring thermal imaging of the user's face, thermal information of the user's face can be acquired. By acquiring ultrasonic imaging of the user's face, the user's uneven facial features can be acquired. By analyzing the above information, the specific positions of the user's face, mouth, nose, ears, eyes, neck, etc. can be identified, and then the corresponding tooth position information can be obtained through the AI ​​algorithm.

[0057] Exemplarily, the energy receiving device 130 is a camera, which can capture images, and the images can be images of human features (including face, mouth, nose, ears, eyes, neck, etc.). According to the image captured by the camera, combined with the AI ​​algorithm, the position of the care part 120 in the user's mouth can be relatively accurately determined. According to the determined position, the brushing conditions of each brushing position of the user can be monitored and indicated, such as judging whether the brushing time of each position is up to standard, whether the brushing strength and brushing amplitude of each position are standardized, etc., so as to prompt the user, or output the correct guidance to the user. For example, when the user misses brushing part of the tooth surface, or the brushing time is not enough, the oral care device 100 can prompt the user, thereby reducing the user's risk of tooth decay. For example, when the brushing time of part of the tooth surface is not enough, the user is prompted to continue brushing the tooth surface, or when the brushing time of a certain tooth surface reaches the preset time, the user is reminded to change the brushing position.

[0058] The energy receiving device 130 has a preset receiving range, which is the maximum range in which the energy receiving device 130 can receive energy. It is understandable that the range in which the energy receiving device 130 receives energy is usually limited, so it is difficult to receive information in every direction. When the orientation of the energy receiving device 130 changes, the area in which it receives energy information changes. For example, when the energy receiving device 130 is a camera, the preset receiving range is the field of view of the camera. Objects within the field of view can be photographed by the camera, and objects outside the field of view cannot be photographed by the camera.

[0059] The care piece 120 is outside the preset receiving range, that is, when the oral care device 100 is used, the energy reflected by the care piece 120 cannot be received by the energy receiving device 130, and the energy receiving device 130 can only receive the energy reflected by the user's face. The oral care device 100 can only identify the position of the teeth through the energy reflected by the user's face. Figure 6As shown, the energy receiving device 130 is arranged toward the care piece 120, that is, in order to ensure that the energy receiving device 130 is not blocked by the handle 111, the energy receiving device 130 needs to be biased inward relative to the care piece 120. A larger portion of the energy receiving device 130 is exposed outside the handle 111, and thus the protrusion of the energy receiving device 130 on the handle 111 is higher.

[0060] like Figure 7 As shown, the care component 120 is located outside the preset receiving range of the energy receiving device 130, and thus the energy receiving device 130 needs to be biased outward relative to the care component 120. After the energy receiving device 130 is biased outward, the shielding of the energy receiving device 130 by the handle 111 will be greatly reduced, and the energy receiving device 130 can be set at a more internal position of the handle 111, that is, the protrusion of the energy receiving device 130 on the handle 111 is lower or there is no protrusion.

[0061] Based on the oral care device 100 of the embodiment of the present application, since the care piece 120 is located outside the preset receiving range, the energy receiving device 130 does not need to be set toward the care piece 120, and the position setting of the energy receiving device 130 on the handle assembly can be more flexible. Moreover, since the care piece 120 is located outside the preset receiving range, the care piece 120 will not block the energy reflected by the user's face, so that the energy receiving device 130 can receive more human body feature information. In addition, since the care piece 120 is located outside the preset receiving range, the energy receiving device 130 can often only receive human body feature information in the half of the preset receiving range close to the care piece 120, thereby reducing the amount of calculation. When the energy receiving device 130 is set on the circumferential surface of the handle 111, the energy receiving device 130 can be set at a larger inclination angle, so that the protrusion of the energy receiving device 130 on the handle 111 is smaller, and the thickness of the handle 111 in the circumferential direction is smaller.

[0062] It should be noted that when the energy receiving device 130 is a camera, although increasing the field of view of the camera can appropriately alleviate the problem of the camera protruding and the handle 111, the larger the field of view of the camera, the more serious the deformation of the image near the camera, thereby increasing the difficulty of recognizing the image.

[0063] like Figure 7As shown, in some embodiments, the oral care device 100 further includes an energy transmitting device 150, and the energy transmitting device 150 is connected to the movement 112 or the handle 111, and the energy transmitting device 150 only needs to be fixed. For example, the energy transmitting device 150 is arranged on the handle 111, and in this case, the energy transmitting device 150 and the movement 112 are arranged separately, or the energy transmitting device 150 is arranged on the movement 112, and in this case, the energy transmitting device 150 can be used as a part of the movement 112. The energy transmitting device 150 and the movement 112 or the handle 111 can be connected by clamping, bonding, welding, etc. The energy transmitting device 150 can be arranged separately from the energy receiving device 130 or arranged integrally.

[0064] The energy transmitting device 150 is used to transmit energy to the human body, and the energy will be reflected after hitting the human body. The energy transmitting device 150 is set corresponding to the receiving port 111b. The energy emitted by the energy transmitting device 150 is reflected by the user's face to form reflected energy, and the reflected energy can pass through the receiving port 111b and be received by the energy receiving device 130. The care part 120 is located outside the preset transmission range, that is, the care part 120 does not reflect energy, so the energy receiving device 130 does not receive the energy reflected by the care part 120. By setting the energy transmitting device 150, the detection reliability can be improved and the influence of ambient light can be reduced. It is also possible to reasonably set the type of the energy transmitting device 150 so that the energy receiving device 130 does not obtain an image of the human body, thereby reducing the risk of privacy leakage. The energy transmitting device 150 and the energy receiving device 130 can be encapsulated in one component and presented in the form of one component to ensure the assembly consistency and relative position stability of the two.

[0065] Exemplarily, when the energy receiving device 130 is a sound wave sensor, the energy transmitting device 150 is used to transmit sound waves, and the sound waves are received by the sound wave sensor after being reflected from the user's face.

[0066] When the energy receiving device 130 is a photoelectric sensor, the energy transmitting device 150 is used to transmit light waves, which are received by the photoelectric sensor after being reflected from the user's face. Alternatively, the energy transmitting device 150 may not be provided, and the photoelectric sensor receives the reflection of light waves from the user's face in nature.

[0067] When the energy receiving device 130 is an infrared sensor, the energy transmitting device 150 is used to transmit infrared light, and the infrared light is received by the photoelectric sensor after being reflected from the user's face. Alternatively, the energy transmitting device 150 may not be provided, and the infrared sensor receives infrared light emitted by the user's face itself, or the infrared sensor receives infrared light reflected from the user's face in nature.

[0068] When the energy receiving device 130 is a camera, the energy transmitting device 150 is used to transmit visible light, and the visible light is received by the camera after being reflected from the user's face. Alternatively, the energy transmitting device 150 may not be provided, and the camera receives the reflection of natural light from the user's face.

[0069] like Figure 7 As shown, in some embodiments, the preset receiving range covers the preset transmitting range, that is, the preset receiving range is greater than or equal to the preset transmitting range. The preset receiving range is the range formed by the dotted lines on both sides of the optical axis 111h in the figure, and the preset transmitting range is the range formed by the long and short dashed lines in the figure. Since the user's face usually appears in the part of the preset receiving range close to the care part 120, the preset transmitting range only needs to cover the part of the preset receiving range close to the care part 120, that is, the energy emitted by the energy transmitting device 150 can cover the user's face, thereby reducing the specification requirements for the energy transmitting device 150, or the setting position of the energy transmitting device 150 can be more flexible. In this way, it is ensured that the energy receiving device 130 can receive more human body / face reflected energy, and then can identify more features, and then can more accurately analyze and obtain the corresponding oral care position.

[0070] like Figure 7 and Figure 8 As shown, in some embodiments of the present application, the energy receiving device 130 includes a camera, the camera has an optical axis 111h, the output axis 1121 has an axis 112a, and the angle between the optical axis 111h and the axis 112a is greater than or equal to F degrees and less than or equal to F+10 degrees, where F is half of the field of view of the camera.

[0071] When the angle between the optical axis 111h and the axis 112a is equal to F degrees, the edge line of the camera's field of view is parallel to the axis 112a of the output shaft 1121, and when the user puts the care piece 120 into the oral cavity, the camera can capture enough of the user's face. If the deflection is too much, the camera captures too small a picture of the user's face, thereby affecting the accuracy of the judgment.

[0072] In some embodiments of the present application, the energy receiving device 130 includes a camera, and the camera has an optical axis 111h, and the optical axis 111h is set to deviate from the care piece 120 so that the care piece 120 is located outside the preset receiving range. The optical axis 111h is set to deviate from the care piece 120, that is, the camera is tilted relative to the output shaft 1121, so that the portion of the camera protruding from the handle 111 is small or does not protrude from the handle 111, thereby reducing the radial size of the handle 111. When the camera does not protrude from the handle 111, the camera can be set inside the handle 111, that is, the camera can be hidden, thereby improving the protection effect of the camera and increasing the service life of the camera.

[0073] In some embodiments of the present application, the optical axis 111h is deviated outward relative to the care part 120, that is, the optical axis 111h is deflected in a direction away from the care part 120, so that the camera is tilted relative to the output axis 1121, so that the camera has less protrusion in the radial direction of the handle 111, and the arrangement of the camera is more flexible.

[0074] like Fig. 9 and Fig.10 As shown, in some embodiments of the present application, the handle 111 includes a top end close to the care piece 120 and a bottom end away from the care piece 120, and the distance between the receiving port 111b and the top end is less than or equal to 40 mm, or the distance between the receiving port 111b and the bottom end is less than or equal to 40 mm.

[0075] The above-mentioned area is usually the area that the user will not hold when using the oral care device 100. Therefore, setting the receiving port 111b in the above-mentioned area can avoid the receiving port 111b being blocked by the hand and avoid the discomfort of holding caused by the protrusion of the light inlet in the circumferential direction.

[0076] Since the energy receiving device 130 can be set at a larger inclination angle, the energy receiving device 130 can protrude less radially in the handle 111, and the probability of being blocked by the handle 111 itself is smaller, and the position setting of the energy receiving device 130 is more flexible. Compared with the energy receiving device 130 being set toward the care part 120, under the same protrusion size, the energy receiving device 130 of this embodiment can be set at a position farther from the care part 120, for example, at the bottom end of the handle 111. The farther the energy receiving device 130 is from the care part 120, the lower the probability of being blocked by liquid or foam.

[0077] like Figure 11-14 As shown, the dotted box represents the range that the oral care device 100 can recognize. Fig.11 Schematic diagram of using the oral care device 100 to clean the upper left teeth. Fig.12 Schematic diagram of using the oral care device 100 to clean the left lower teeth. Fig.13 Schematic diagram of using the oral care device 100 to clean the left upper molars. Fig.14 Schematic diagram of using the oral care device 100 to clean the left lower molar. Figure 11-14 It can be seen that the oral care device 100 can capture more facial images, thereby ensuring that the oral care device 100 has a higher recognition accuracy. Since the left and right sides are symmetrical, it also has a higher recognition rate when cleaning the symmetrical position of the right oral cavity.

[0078] like Fig.15This is a schematic diagram of using the oral care device 100 to clean the front teeth. In this case, since the energy receiving device 130 is roughly parallel to the face, the oral care device 100 can capture relatively few facial images and the recognition rate is relatively low.

[0079] In some embodiments of the present application, the oral care device 100 further includes a multi-axis sensor, which is used to obtain posture information of the oral care device 100. The multi-axis sensor may include, but is not limited to, a three-axis acceleration sensor and / or a three-axis gyroscope sensor. The posture information may include, but is not limited to, acceleration and direction of the oral care device in three-dimensional space and / or a rotation angle, rotation speed, and rotation axis of the oral care device in three-dimensional space.

[0080] Different posture information corresponds to different postures of the oral care device 100. Through multiple simulation tests, different posture information can be matched to different postures of the oral care device 100. Different postures of the oral care device 100 represent different positions of cleaning the oral cavity. Through multiple simulation tests, different postures of the oral care device 100 can be matched to different positions of cleaning the oral cavity, so that which part of the oral cavity is currently being cleaned by the oral care device 100 can be determined based on the posture information.

[0081] By providing posture information and human feature information as more input information to the AI ​​processing model, a more accurate position can be obtained. Or when there is less human feature information, the brushing position can be obtained in combination with the posture information. Through dual calibration based on human feature information and posture information, the current oral care position corresponding to the care piece 120 can be more accurately identified.

[0082] For example, the human body feature information is used to determine whether the care component 120 is currently in the upper or lower dental area, and the posture information is used to determine the orientation of the care component 120, thereby more accurately judging whether the care component 120 is currently in the left dental area, the right dental area, or the middle dental area. Finally, the determined upper and lower positions and left and right positions are combined to obtain a more accurate current oral care position corresponding to the care component 120.

[0083] Alternatively, after obtaining the human body feature information and posture information, the first current oral care position corresponding to the care piece 120 may be determined based on the human body feature information, the second current oral care position corresponding to the care piece 120 may be determined based on the posture information, and then the current oral care position corresponding to the care piece 120 may be determined based on the first current oral care position and the second current oral care position. For example, but not limited to, the current oral care position corresponding to the care piece 120 may be the overlapping position of the first current oral care position and the second current oral care position.

[0084] like Fig.16 and Fig.17 As shown, in some embodiments of the present application, the handle 111 includes a transition section 1111 and a grip section 1112, the transition section 1111 has a first connection end 1113 and a second connection end 1114 close to the care piece 120, the grip section 1112 is connected to the first connection end 1113, and the area of ​​the cross section of the transition section 1111 perpendicular to the length direction EE of the oral care device 100 gradually decreases from the first connection end 1113 to the second connection end 1114. It should be noted that the area of ​​the cross section of the transition section 1111 perpendicular to the length direction EE of the oral care device 100 can be smoothly reduced or stepped. The receiving port 111b is provided on the transition section 1111, and the receiving port 111b is spaced apart from the care piece 120.

[0085] Based on the oral care device 100 of the embodiment of the present application, the transition section 1111 gradually tapers from the first connection end 1113 to the second connection end 1114, so that the transition section 1111 can avoid blocking the energy entering the receiving port 111b as much as possible, so that the energy receiving device 130 can better obtain energy information. In addition, the water on the care piece 120 can flow smoothly from the second connection end 1114 to the first connection end 1113, and then drain along the grip section 1112, so that the water on the care piece 120 is not easy to block the receiving port 111b. The receiving port 111b can be set in the transition section 1111, or the receiving port 111b is set in the grip section 1112, or the receiving port 111b is set at the junction of the transition section 1111 and the grip section 1112, and it can be set according to actual needs.

[0086] In some embodiments of the present application, the receiving port 111b is disposed in the transition section 1111, and the receiving port 111b is flush with the outer surface of the transition section 1111. That is, the outer surface of the transition section 1111 is a smooth surface, so that the junction between the transition section 1111 and the receiving port 111b is not easy to hide dirt, and liquid and foam are difficult to adhere to the transition section 1111.

[0087] In some embodiments of the present application, the receiving port 111b is arranged at the gripping section 1112, or the receiving port 111b is arranged at the junction of the gripping section 1112 and the transition section 1111, and the receiving port 111b is protruded from the outer surface of the handle 111, thereby reducing the obstruction of the receiving port 111b by the handle 111.

[0088] like Fig.16 and Fig.17As shown, in some embodiments of the present application, the handle assembly 110 also includes a protruding structure 113, and the protruding structure 113 is protruded on the outer peripheral wall of the handle 111 along the radial direction of the handle 111. The protruding position of the protruding structure 113 can be at the top, bottom or middle of the handle 111, which is not limited here. The protruding structure 113 and the handle 111 can be integrally formed, thereby reducing the manufacturing process and improving the waterproof performance of the protruding structure 113 and the handle 111 as a whole. Or the protruding structure 113 and the handle 111 can be separately arranged, so that protruding structures 113 of different specifications can be flexibly matched with handles 111 of different specifications, and the connection method between the protruding structure 113 and the handle 111 can be clamping, bonding, welding, etc. The receiving port 111b is arranged on the surface of the protruding structure 113 facing the care piece 120.

[0089] Based on the oral care device 100 of the embodiment of the present application, by providing the protruding structure 113, the shielding of the handle 111 on the energy entering the receiving port 111b can be reduced, so that the energy receiving device 130 can better receive human body feature information.

[0090] In some embodiments of the present application, the receiving port 111b is located on the side of the protruding structure 113 that is away from the handle 111 on the mirror image of the handle 111, that is, when the size of the protruding structure 113 remains unchanged, the receiving port 111b is set as far away from the handle 111 as possible, and the interval between the receiving port 111b and the handle 111 is relatively large, so that the liquid on the handle 111 is difficult to flow to the receiving port 111b, and the handle 111 will not excessively block the receiving port 111b.

[0091] Based on the oral care device 100 of the embodiment of the present application, the receiving port 111b is far away from the handle 111, which can increase the difficulty of the liquid on the handle 111 flowing to the receiving port 111b, thereby reducing the probability of the liquid flowing to the receiving port 111b and improving the waterproofness of the receiving port 111b. In addition, the receiving port 111b is far away from the handle 111, which can also make the distance between the energy receiving device 130 and the handle 111 as large as possible, so as to facilitate the energy receiving device 130 to receive human body feature information.

[0092] like Figure 4As shown, in some embodiments of the present application, the energy receiving device 130 includes a camera, and the oral care device 100 also includes a light-transmitting member 140, which is light-transmitting, and the light-transmitting member 140 covers the receiving port 111b to seal the receiving port 111b. The light-transmitting member 140 can be arranged on the outer surface of the handle 111. The light-transmitting member 140 and the handle 111 can be integrally formed, so that the production process can be simplified, and the light-transmitting member 140 and the handle 111 as a whole have a good waterproof effect. Alternatively, the light-transmitting member 140 and the handle 111 can be connected in a split manner, for example, the light-transmitting member 140 and the handle 111 are connected by means of clamping, bonding, welding, etc., so as to realize flexible assembly of light-transmitting members 140 of different specifications and handles 111 of different specifications.

[0093] The light-transmitting member 140 can be a light-transmitting plastic sheet or a light-transmitting glass sheet. It should be noted that the light-transmitting member 140 can be a flat glass or a curved glass, so as to have a bending force on light, so as to cooperate with the energy receiving device 130 to achieve a specific optical effect, such as wide-angle shooting.

[0094] The outer surface of the light-transmitting member 140 is coated with a hydrophobic film 141, which can be a light-transmitting nano-film. It is understandable that the outer surface of the light-transmitting member 140 can also be coated with other types of coatings, such as optical coatings.

[0095] Based on the oral care device 100 of the embodiment of the present application, the outer surface of the light-transmitting member 140 is covered with a hydrophobic film 141, so that the outer surface of the light-transmitting member 140 has a large water contact angle, and liquids such as water droplets are not easy to adhere to the outer surface of the light-transmitting member 140, so that the outer surface of the light-transmitting member 140 can be kept as clean as possible, reducing the negative impact of liquids such as water droplets on the shooting of the energy receiving device 130, and also making the light-transmitting member 140 easy to clean. In addition, liquids such as water droplets are not easy to adhere to the outer surface of the light-transmitting member 140, that is, the time that the liquid stays on the light-transmitting member 140 is reduced. When the light-transmitting member 140 and the handle 111 are integrally arranged, the probability of water leakage at the junction of the light-transmitting member 140 and the handle 111 can also be reduced.

[0096] like Fig.16 and Fig.17 As shown, in some embodiments of the present application, the light-transmitting member 140 is tilted to guide the liquid to flow out of the light-transmitting member 140. Preferably, when the oral care device 100 is in a common holding posture and a common placement state, the light-transmitting member 140 has an angle with the horizontal plane, so as to facilitate liquids such as water drops to slide off the outer surface of the light-transmitting member 140.

[0097] Based on the oral care device 100 of the embodiment of the present application, by tilting the light-transmitting member 140 to guide the liquid to flow out of the light-transmitting member 140, the outer surface of the light-transmitting member 140 can be kept as clean as possible, reducing the negative impact of liquids such as water droplets on the shooting of the energy receiving device 130. In addition, the drainage effect generated by the tilted light-transmitting member 140 is relatively stable and reliable, and the effect will not be degraded due to long-term use.

[0098] In some embodiments of the present application, the camera and the receiving port 111b are arranged opposite to each other, so that the camera can receive as much human feature information as possible from the receiving port 111b. The size of the receiving port 111b can be adapted to the light-incoming surface of the camera. If the receiving port 111b is too large, too much stray light will enter the camera. If the receiving port 111b is too small, too little image will enter the camera. The camera and the light-transmitting member 140 have the same inclination angle, so that the camera and the light-transmitting member 140 can be as close together as possible, thereby reducing the volume of the camera and the handle 111 after assembly.

[0099] like Fig.16 As shown, in some embodiments of the present application, in the circumferential dimension of the handle 111, if the face where the button 160 on the handle 111 is located or the care-oriented face of the care piece 120 is the front face, the energy receiving device 130 is arranged on the back face of the handle 111. For example, the care piece 120 includes bristles 121, and the face of the handle 111 that faces the same direction as the brushing face of the bristles 121 is the front face 111g of the handle 111, and the receiving port 111b is arranged on the back face 111f of the handle 111. Alternatively, the oral care device 100 includes a button 160, and the button 160 is arranged on the front face 111g of the handle 111, and the receiving port 111b is arranged on the back face 111f of the handle 111. It should be noted that, in this embodiment, since the shape of the handle 111 may be roughly cylindrical, the front 111g and the back 111f of the handle 111 are relative concepts, and the front 111g and the back 111f of the handle 111 may both be curved surfaces, and the front 111g and the back 111f of the handle 111 may be connected. It should be noted that the button 160 and the receiving port 111b are not limited to being directly opposite to each other on both sides of the length direction EE of the oral care device 100. For example, the button 160 is set in the middle or upper middle position of the front 111g of the handle 111, and the receiving port 111b is set at the top position of the back 111f of the handle 111.

[0100] Based on the oral care device 100 of the embodiment of the present application, the energy receiving device 130 is arranged on the back. When brushing teeth, the energy receiving device 130 is on the outside away from the human body. Relatively speaking, the energy receiving device 130 is farther away from the user's chin, thereby reducing the probability of the energy receiving device 130 being blocked by the chin. In addition, the energy receiving device 130 is arranged on the back 111f of the handle 111. When the oral care device 100 is placed, the care part 120 will block the optical path of the energy receiving device 130, and it is difficult for the energy receiving device 130 to capture the user's privacy image. In addition, since the energy receiving device 130 is arranged toward the care part 120, when the oral care device 100 is placed on the sink, the energy receiving device 130 faces obliquely upward, that is, the energy receiving device 130 faces the ceiling of the bathroom, so it is also difficult to capture the user's privacy image.

[0101] like Fig.17 As shown, in some embodiments of the present application, the oral care device 100 further includes a light source 170, which can be disposed on the handle 111, or the light source 170 can be disposed on the protruding structure 113 (in this case, the light source 170 is equivalent to being indirectly disposed on the handle 111 through the protruding structure 113), and the light source 170 is used to fill light for the energy receiving device 130, so as to improve the clarity of the image when the energy receiving device 130 is photographed in a dark light environment. The light source 170 can be illustratively an LED lamp bead, which has a relatively high brightness and is power-saving. The light emitted by the light source 170 is preferably soft light, thereby reducing the stimulation to the user's eyes. The light source 170 can be configured to open and close synchronously with the energy receiving device 130 to prompt the user of the working status of the energy receiving device 130. Of course, the light source 170 can also have other opening conditions, for example, the light source 170 can be configured to be turned on only when the brightness value of the ambient light is lower than a certain threshold.

[0102] Based on the oral care device 100 of the embodiment of the present application, the light source 170 can supplement the energy receiving device 130 with light, thereby increasing the amount of light entering the energy receiving device 130, improving the shooting effect of the energy receiving device 130, and further expanding the use scenario of the oral care device 100. Moreover, since the light source 170 and the energy receiving device 130 are turned on and off synchronously, that is, when the light source 170 is turned off, the energy receiving device 130 is turned off, and when the light source 170 is working, the energy receiving device 130 is working, the user can judge whether the energy receiving device 130 is working according to whether the light source 170 is turned on, so that the user can know the working status of the energy receiving device 130 more intuitively, avoiding the user's privacy disclosure when he is not aware of it.

[0103] It is understandable that when there is sufficient light, the light source 170 does not need to be always on for fill light. In this case, the light source 170 can only light up for a certain period of time or flash a few times when the energy receiving device 130 is turned on, prompting the user that the energy receiving device 130 is turned on. Then the energy receiving device 130 can continue to be turned on, but the light source 170 can be turned off.

[0104] like Figure 4 As shown, in some embodiments of the present application, the movement 112 includes a bracket 180, a battery, a motor, and a circuit board, etc. The battery, the motor, and the circuit board are arranged on the bracket 180, and the energy receiving device 130 is also arranged on the bracket 180. The light-incoming surface of the energy receiving device 130 is arranged opposite to the receiving port 111b. It should be noted that during assembly, the energy receiving device 130 is first assembled on the bracket 180, and then the whole assembled with the energy receiving device 130, the battery, the motor, the circuit board and the bracket 180 is loaded into the installation cavity 111a through the installation opening 111e. The bracket 180 and the installation cavity 111a can be provided with a guiding structure. When the bracket 180 and the bracket 180 are assembled in place, the light-incoming surface of the energy receiving device 130 is opposite to the receiving port 111b.

[0105] Based on the oral care device 100 of the embodiment of the present application, the orientation of the energy receiving device 130 is limited by the bracket 180, so that the energy receiving device 130 is directly opposite to the receiving port 111b, thereby ensuring that the field of view of the energy receiving device 130 is not blocked. Moreover, the light-incoming surface of the energy receiving device 130 can be arranged as close to the receiving port 111b as possible, thereby making the structure of the oral care device 100 more compact.

[0106] like Fig.18 As shown, in some embodiments of the present application, the handle 111 further has an installation opening 111e communicating with the installation cavity 111a, the energy receiving device 130 is disposed on the movement 112, and the whole formed by the energy receiving device 130 and the movement 112 can be installed in the installation cavity 111a through the installation opening 111e. The installation opening 111e can be disposed at the bottom of the handle 111, so that it is difficult for liquid to flow back from the opening to the installation cavity 111a.

[0107] Based on the oral care device 100 of the embodiment of the present application, the energy receiving device 130 is connected to the movement 112, and the energy receiving device 130 and the movement 112 can be assembled together into the handle 111, thereby reducing the assembly steps and improving the assembly efficiency.

[0108] In some embodiments of the present application, the oral care device 100 further includes a controller, which is disposed in the handle 111, for example, in the mounting cavity 111a of the handle 111. The controller is electrically connected to the energy receiving device 130, and the controller is used to determine the position of the care component 120 in the oral cavity based on the image acquired by the energy receiving device 130 (for example, the image of the care component 120 and the human body feature image), and calculate the current tooth surface position of brushing. Of course, the controller can also control the opening and closing of the energy receiving device 130. The controller can be disposed on the aforementioned circuit board.

[0109] Alternatively, the oral care device 100 further includes a communication module, which is used to send the image (e.g., the image of the care piece 120 and the human body feature image) acquired by the energy receiving device 130 to an external terminal, and the external terminal can determine the position of the care piece 120 in the oral cavity based on the image acquired by the energy receiving device 130. The external terminal can also determine the possible oral disease risk based on the user's brushing record. The communication module can be set on the aforementioned circuit board.

[0110] Based on the oral care device 100 of the embodiment of the present application, the controller or external terminal can determine the position of the care component 120 in the oral cavity according to the image obtained by the energy receiving device 130, and prompt the user, for example, through the display screen on the oral care device 100, to realize the brush-while-watching function, thereby helping the user to improve the efficiency of brushing.
