Description

Technical Field

[0001] The present application relates to the field of oral cleaning, and more specifically, to an oral care device. Background Art

[0002] Oral care devices are electric devices that use a high-speed vibration movement motor to drive the care parts to rotate or vibrate to clean teeth. According to user needs, some oral care devices are equipped with receiving devices such as cameras for reading external environmental information to monitor the user's teeth cleaning process. However, in the related art, the receiving devices provided on the oral care devices are mostly located on the surface of the oral care devices or require a groove for installing the receiving devices on the outer shell of the oral care devices. The structure is complex, the assembly steps are more, and the production speed is slow. Utility Model Content

[0003] The embodiments of the present application provide an oral care device, which is at least used to solve the problem of complex structure of the oral care device.

[0004] The oral care device of the embodiment of the present application includes a handle shell, a core assembly, a care piece and an energy receiving module. The core assembly is disposed in the handle shell and partially extends out of the handle shell. The care piece is disposed at one end of the handle shell and is located outside the handle shell, and the care piece is connected to the portion of the core assembly extending out of the handle shell. The energy receiving module is disposed in the core assembly and faces the care piece, and the energy receiving module faces the side where the care piece is located, so that at least part of the structure of the care piece is located within the receiving range of the energy receiving module; the energy receiving module is used to receive at least part of the energy reflected by the care piece and / or human body features outside the oral cavity.

[0005] Compared with the solution in which the energy receiving module is arranged outside the handle shell, the energy receiving module arranged in the movement assembly can be directly electrically connected to other structures of the oral care device in the handle shell without opening holes on the surface of the handle shell, and the sealing and waterproof performance of the oral care device is better.

[0006] In some embodiments, the movement assembly includes a driving member, a power source, and a mounting bracket. At least a portion of the structure of the output shaft of the driving member extends from the handle shell and is connected to the nursing member, and the output shaft of the driving member is used to drive the nursing member to vibrate. The power source is electrically connected to the driving member. The mounting bracket is fixed to the handle shell, the driving member and the power source are movably mounted on the mounting bracket, and the energy receiving module is arranged on the mounting bracket and faces the nursing member.

[0007] The mounting bracket can be used to mount the driver and the power supply to prevent the driver and the power supply from shaking in the handle shell. The energy receiving module is mounted on the mounting bracket to avoid direct contact with the driver and resonance, and to avoid affecting the energy receiving module's reception of at least part of the energy reflected by the care piece and / or the human body features outside the oral cavity.

[0008] In some embodiments, the mounting bracket is provided with a mounting portion, the mounting portion protruding from the outer surface of the mounting bracket and spaced apart from the handle shell. Compared with the mounting bracket, the mounting portion is closer to the inner wall of the handle shell; the energy receiving module is arranged on the mounting portion and faces the nursing component.

[0009] The energy receiving module arranged on the mounting part can be closer to the side of the oral care device away from the central axis. On the one hand, the energy receiving module can be more stably installed on the mounting bracket. On the other hand, the energy receiving module can receive energy at a wider viewing angle and will not be excessively blocked by the care parts, so more effective information can be obtained.

[0010] In some embodiments, the oral care device further comprises a circuit board and a connecting wire. The circuit board is arranged outside the mounting bracket and is electrically connected to the energy receiving module. One end of the connecting wire is electrically connected to the circuit board, and the other end of the connecting wire is electrically connected to the energy receiving module.

[0011] The connecting wire can electrically connect the circuit board and the energy receiving module. When the energy receiving module receives external energy, the energy receiving module can convert the received external energy into an electrical signal and transmit the electrical signal to the circuit board and the control module electrically connected to the circuit board via the connecting wire, so as to analyze the electrical signal or control the operation mode of the energy receiving module, etc.

[0012] In certain embodiments, a wire groove is provided in the mounting bracket, and the connecting wire is provided in the wire groove and is located between the driving member and the inner wall of the wire groove.

[0013] The wire trough can be used to fix the connecting wires passed through the mounting bracket. On the one hand, the wire trough can fix the relative position relationship between the connecting wires and the mounting bracket. On the other hand, the wire trough can also prevent excessive entanglement and friction between the driving component and the connecting wires, thereby avoiding damage to the connecting wires.

[0014] In some embodiments, the mounting bracket is provided with a first threading hole, the mounting portion is provided with a second threading hole, the second threading hole is communicated with the wire groove, and the first threading hole is communicated with the mounting space in the mounting bracket. The connecting wire electrically connected to the circuit board passes through the first threading hole and enters the wire groove, and the connecting wire in the wire groove passes through the second threading hole to be electrically connected to the energy receiving module.

[0015] Compared with the solution in which the connecting wire bypasses the mounting bracket, the connecting wire passing through the inside of the mounting bracket can shorten the length required for the connecting wire to connect the circuit board and the energy receiving module, and can also prevent the wires from being entangled between the mounting bracket and the handle shell, causing damage to the connecting wire.

[0016] In certain embodiments, the mounting portion is provided with a mounting groove, and the energy receiving module is at least partially accommodated in the mounting groove and connected to an inner wall of the mounting groove.

[0017] The mounting groove can fix the energy receiving module on at least two opposite sides to prevent the energy receiving module from shaking violently relative to the mounting portion when the driving member is running, so as to avoid affecting the energy acquisition range of the energy receiving module and causing incomplete or erroneous information. On the other hand, it can also prevent the energy receiving module from falling off from the mounting portion.

[0018] In some embodiments, the mounting bracket includes a first mounting shell and a second mounting shell connected to each other, the first mounting shell and the second mounting shell are arranged opposite to each other and form a mounting space, and at least a part of the structure of the driving member is arranged in the mounting space.

[0019] The first mounting shell and the second mounting shell that can be mounted to each other can be used to accommodate and protect the driving member, and the first mounting shell and the second mounting shell can be used to support the energy receiving module. During the installation process, the connecting wire and the driving member can be placed in at least one of the first mounting shell and the second mounting shell, and then the other of the first mounting shell and the second mounting shell can be installed. The energy receiving module can be installed after the mounting bracket is assembled, which is more convenient to install.

[0020] In some embodiments, along a direction perpendicular to and away from the central axis of the handle shell, the handle shell includes a first side and a second side opposite to each other, the first mounting shell is located on the side where the first side of the handle shell is located, the second mounting shell is located on the side where the second side of the handle shell is located, and the energy receiving module is arranged outside the second mounting shell.

[0021] The first mounting shell and the second mounting shell arranged opposite to each other in a direction perpendicular to and away from the central axis of the handle shell can form a large space between the inner wall of the first side of the handle shell and the first mounting shell, and between the inner wall of the second side of the handle shell and the second mounting shell. At this time, there is also a large gap between the energy receiving module arranged on the second mounting shell and the inner wall of the second side of the handle shell. This avoids extrusion or collision between the handle shell and the energy receiving module, and protects the energy receiving module.

[0022] In some embodiments, along the extension direction of the central axis of the handle shell, the first mounting shell is disposed on a side of the driving member close to the care member, the second mounting shell is disposed on a side of the driving member away from the care member, and the energy receiving module is disposed outside the first mounting shell.

[0023] The first mounting shell and the second mounting shell arranged along the extension direction of the central axis of the handle shell are roughly cylindrical structures with one end open. The driving member can be inserted into any one of the first mounting shell and the second mounting shell during installation. When the driving member is installed in the first mounting shell or the second mounting shell, the connection between the driving member and the first mounting shell or the second mounting shell is more stable and not easy to fall off. The energy receiving module is close to the nursing part, and the receiving effect is good.

[0024] In some embodiments, a first guide rail is provided on the outside of the first mounting shell, and a first guide groove corresponding to the first guide rail is provided on the inner wall of the handle shell, and the first guide rail is used to cooperate with the first guide groove to fix the mounting bracket to the handle shell and / or a second guide rail is provided on the outside of the second mounting shell, and a second guide groove corresponding to the second guide rail is provided on the inner wall of the handle shell, and the second guide rail is used to cooperate with the second guide groove to fix the mounting bracket to the handle shell.

[0025] When the first guide rail and the second guide rail are both clamped in the corresponding first guide groove and the second guide groove, the mounting bracket and the handle shell are fixed to each other through the combination of the guide rail and the guide groove without shaking or even rotating, and the connection between the mounting bracket and the handle shell is more stable.

[0026] In certain embodiments, a limiting portion is provided in the handle shell, and when the mounting bracket is in cooperation and abutment with the limiting portion, the movement assembly is installed in the handle shell, and the energy receiving module is spaced apart from the handle shell.

[0027] The limiting portion can abut against the mounting bracket and create a gap between the outer wall of the mounting bracket and the inner wall of the handle shell. At this time, when the driving member slides slightly in the handle shell, the energy receiving module will not be squeezed between the handle shell, causing damage to the energy receiving module.

[0028] In some embodiments, the handle shell includes an end shell portion and a peripheral shell portion. The care component is disposed at one end of the end shell portion, the energy receiving module is located in the end shell portion, and the energy receiving module faces the end shell portion. The peripheral shell portion is connected to the end shell portion and is disposed at the other end of the end shell portion.

[0029] Compared with the peripheral shell part, the end shell part is closer to the side where the care part is located. When the energy receiving module is arranged at the end shell part, the distance between the energy receiving module and the care part is closer. At this time, the energy reflected by the care part and / or the human body features outside the oral cavity can enter the energy receiving module more, so that the energy receiving module can obtain more information.

[0030] In certain embodiments, along the extension direction of the central axis of the handle shell, the maximum distance between the inner wall of the end shell portion and the energy receiving module on the same straight line is less than 5 mm.

[0031] Since the range of energy receiving module to obtain energy information is roughly a divergent cone angle, when the distance between the energy receiving module and the inner wall of the end shell is too large, the energy receiving module is more likely to be blocked by the structure connected to the end shell, affecting the energy receiving module's reception of energy. When the distance is moderate, the energy receiving module is blocked by the nursing parts and other structures to a smaller extent or even not blocked, so the energy receiving module receives more energy.

[0032] In certain embodiments, along the extension direction of the central axis of the handle shell, the outer contour size of the cross section of the end shell portion gradually decreases.

[0033] Since the end shell portion is roughly a frustum or prism structure and the side of the end shell portion with a smaller outer contour is arranged close to the care piece, during the use of the oral care device, liquid and foam flowing down from the care piece are not easy to remain on the surface of the end shell portion but will slide down along the outer wall of the end shell portion, thereby avoiding liquid and foam from affecting the energy receiving module's reception of energy.

[0034] In some embodiments, the plane where the inner surface of the end shell portion and the energy receiving module corresponds is parallel to the plane where the energy receiving module is located, or the angle between the plane where the inner surface of the end shell portion and the energy receiving module corresponds is less than 15°.

[0035] When the two planes relative to the end shell and the energy receiving module are parallel or the angle between them is less than 15°, the energy receiving range of the energy receiving module is only the nursing part and the two sides of the nursing part, and there will be no other structures that will block the information (for example: the output shaft of the driving part, the seal, etc.). At this time, the energy receiving module receives more energy and the information that the energy receiving module can obtain is more complete.

[0036] In some embodiments, the end shell portion is provided with an opening, and the output shaft of the driving member at least partially extends out of the handle shell from the opening; the oral care device further comprises a sealing member, which is disposed in the handle shell and is used to seal the gap between the output shaft of the driving member and the inner wall of the opening. There is a gap between the sealing member and the inner wall of the end shell portion, and the energy receiving module is disposed in the gap between the sealing member and the handle shell.

[0037] When the oral care device is in working condition, the seal can prevent liquid and foam flowing down from the care component from entering the handle shell through the gap between the handle shell and the output shaft of the driving component. At the same time, when the oral care device is not in working condition, it can also prevent water vapor and dust from entering the handle shell, thereby preventing the internal structure of the oral care device from being damp and rusted or causing the internal circuit of the oral care device to short-circuit or even be damaged.

[0038] In some embodiments, the care part includes a connected rod body and a care part, one end of the rod body is installed on the output shaft of the driving part, and the care part is arranged at the other end of the rod body; when the care part is a brush head, the care part includes a hair transplanting plate and bristles, the hair transplanting plate is arranged at the other end of the rod body, the bristles are arranged on a first side of the hair transplanting plate, the energy receiving module is located on the side where the second side of the hair transplanting plate is located, the first side of the hair transplanting plate is opposite to the second side of the hair transplanting plate, and the second side of the hair transplanting plate to the first side of the hair transplanting plate are all located within the receiving range of the energy receiving module.

[0039] The energy receiving module can analyze the received energy information to form an image or distance and position information. When the receiving range of the energy receiving module includes the opposite sides of the hair implanting plate, the energy receiving module can receive relatively symmetrical information from the opposite sides of the hair implanting plate. Therefore, the image information or distance and position information formed after the energy receiving module analyzes are all symmetrically designed, which makes it easier to determine the position of the care parts of the oral care device during use.

[0040] In some embodiments, along a direction perpendicular to and away from a central axis of the handle shell, a distance between the energy receiving module and the handle shell is no more than 3 mm.

[0041] Since the energy receiving module is arranged at a position far away from the central axis and the receiving range of the energy receiving module is roughly a divergent cone angle, when the energy receiving module is arranged at a position as close to the inner wall of the handle shell as possible, the main axis of the energy receiving module can be aligned with the apex of the care part. At this time, the energy information on both sides of the hair implantation plate of the care part obtained by the energy receiving module can be relatively symmetrical, and the image information, distance and position information obtained by analysis are also relatively symmetrical.

[0042] In some embodiments, the handle shell is provided with an energy-transmitting area and a non-energy-transmitting area, and the energy receiving module faces the energy-transmitting area so that the receiving range of the energy receiving module is offset from the non-energy-transmitting area. At least part of the energy reflected by the care piece and / or the human body features outside the oral cavity enters the energy receiving module through the energy-transmitting area.

[0043] On the one hand, the partially light-transmissive handle shell can shield the internal structure of the oral care device through the opaque part, making the appearance of the oral care device more beautiful. At the same time, the partially light-transmissive handle shell can also limit the angle at which at least part of the energy reflected by the care piece and / or the human body features outside the oral cavity enters the receiving area of ​​the energy receiving module, thereby preventing the energy receiving module from obtaining too much invalid information.

[0044] In some embodiments, the energy receiving module includes an imaging module, which is directed toward the nursing piece and is used to acquire images.

[0045] The imaging module can obtain image information of the care parts and images of human features and / or teeth outside the oral cavity near the care parts through optical elements such as cameras, and determine the tooth area that the care parts are in contact with at this time based on the relative position between the care parts and the human features and / or teeth outside the oral cavity, thereby more accurately positioning the tooth area.

[0046] In some embodiments, the oral care device further comprises a reminder device. When the image analysis shows that the care piece is not suitable, the reminder device is used to issue a reminder message.

[0047] The imaging module can obtain image information of the care parts and obtain relevant information of the care parts based on the obtained image information, such as model, production time and service life, etc. In the case that the care parts replaced by the user are not suitable for the oral care device, the reminder can remind the user to replace the correct care parts to avoid damage to the oral care device.

[0048] In some embodiments, when the imaging module is working, the prompter is used to issue a prompt message.

[0049] Since the imaging module can obtain the extra-oral human features and / or tooth images near the care parts and analyze and record the image information, when the imaging module is working, the reminder sends a reminder message to remind the user to protect personal privacy in time.

[0050] In certain embodiments, when it is determined from the image analysis that the operating time of the care component in the predetermined tooth area is less than a preset time threshold, the prompter is used to issue a prompt message.

[0051] The imaging module can determine whether the care piece is located in the predetermined tooth area at this time according to the positional relationship between the care piece and the human body features outside the oral cavity, and the imaging module can also record the time the care piece stays in the predetermined tooth area and judge the cleaning effect of the care piece in this area accordingly. When the operation time of the care piece staying in the predetermined tooth area is less than the preset time threshold, it can be considered that the cleaning effect of the care piece in this area is not good. The reminder can not only record the cleaning effect of each different tooth area, but also promptly remind the user to extend the time of using the oral care device in the predetermined tooth area.

[0052] In certain embodiments, when it is determined from the image analysis that the usage time of the care component is greater than a preset upper limit, the reminder is used to issue a reminder message.

[0053] Each care part has a fixed optimal use time. When a care part is installed on the output shaft of the driving part of the oral care device, the imaging module can record the installation time of the care part and start recording the use time of the care part. When the use time of the care part reaches or exceeds the preset time limit, the reminder can send a reminder message to the user to prompt the user to replace the new care part.

[0054] In certain embodiments, the oral care device further comprises a display, which is disposed on the first side of the handle shell; the display is used to display relevant information of the care component obtained by analyzing the image.

[0055] The imaging module can obtain image information of the nursing parts. After the imaging module converts the obtained information into electrical signals, it can be transmitted to a circuit board electrically connected to the imaging module. A control module is provided on the circuit board. The control module can obtain relevant information of the nursing parts based on the obtained electrical signals, and transmit the relevant information of the nursing parts to the display in the form of electrical signals for display, so as to facilitate the user to confirm the usage of the oral care device in time.

[0056] In certain embodiments, when the oral care device is awakened, the energy receiving module is activated, or when the energy receiving module is activated and the care component is found to be adapted according to the image analysis, the oral care device is turned on.

[0057] After the oral care device wakes up, the energy receiving module starts and receives at least part of the energy reflected by the care parts and / or the human features outside the oral cavity, and obtains the care parts information, the human features outside the oral cavity, and the relative position relationship between the care parts and the human features outside the oral cavity based on the received part of the energy, so as to accurately determine the current position of the oral care device. When the energy receiving module obtains the care parts information and analyzes that the care parts are compatible, the energy receiving module can send an electrical signal to the control module on the circuit board and automatically start the oral care device. On the one hand, it can avoid damage to the oral care device due to incompatibility of the care parts, and on the other hand, it can also achieve automatic startup of the oral care device.

[0058] In certain embodiments, the oral care device includes an electric toothbrush and an oral scanning device.

[0059] Electric toothbrushes can clean the oral cavity and determine relevant information of care parts by identifying the information of care parts. Electric toothbrushes and oral scanning devices and other equipment with oral care functions can identify human feature information and care part information outside the oral cavity. On the one hand, they can determine the positional relationship between the part of the device extending into the oral cavity and the tooth area, and on the other hand, they can also detect the situation inside the oral cavity.

[0060] In certain embodiments, the oral care device further comprises an energy emitting module for emitting energy, and the energy receiving module is used to receive at least a portion of the energy emitted by the energy emitting module and reflected by the care component and / or human features outside the oral cavity.

[0061] The energy emission module can emit energy outwards, and the energy forms include but are not limited to sound, light, electricity, etc. The energy emitted by the energy emission module can be reflected by the nursing parts and / or human features outside the oral cavity and re-enter the energy receiving module. The energy emission module can control the way and size of the energy emitted outwards, so that the energy receiving module can receive the required reflected energy and analyze it to obtain clear and complete image information or distance position information.

[0075] See also Figure 1 and Figure 2 The oral care device 100 of the present application includes a handle shell 10, a core assembly 20, a care piece and an energy receiving module 40. The core assembly 20 is disposed on the handle shell 10 and partially extends out of the handle shell 10. The care piece is disposed at one end of the handle shell 10 and is located outside the handle shell 10, and the care piece is connected to the portion of the core assembly 20 extending out of the handle shell 10. The energy receiving module 40 is disposed on the core assembly 20 and faces the care piece, and the energy receiving module 40 faces the side where the care piece is located, so that at least part of the structure of the care piece is located within the receiving range of the energy receiving module 40; the energy receiving module 40 is used to receive at least part of the energy reflected by the care piece and / or human body features outside the oral cavity.

[0076] Among them, the energy receiving module 40 can only receive at least part of the energy reflected from the care parts, and at this time, there are only care parts within the receiving range of the energy receiving module 40. The energy receiving module 40 can identify and analyze the characteristics and related parameters of the care parts to obtain the image information of the care parts and the component information of the care parts (such as model, production time and service life, etc.). The energy receiving module 40 can also only receive at least part of the energy reflected from the human body features outside the oral cavity. At this time, the receiving range of the energy receiving module 40 is completely offset from the care parts, that is: there are no care parts within the receiving range of the energy receiving module 40. The energy receiving module 40 can identify and analyze the human body features outside the oral cavity, and obtain relevant information generated by the user when using the oral care device 100, such as usage time, frequency of use, and identity of the user. The energy receiving module 40 can also simultaneously receive at least part of the energy reflected by the care piece and the human features outside the oral cavity. At this time, the care piece and the human features outside the oral cavity are both within the receiving range of the energy receiving module 40. The energy receiving module 40 can analyze the energy reflected by the two to obtain image information or distance and position information of the care piece and the human features outside the oral cavity, and determine the positional relationship between the care piece and the human features outside the oral cavity at this time. For example: in which predetermined tooth area the care piece is located, whether the care piece is in a predetermined working position, and the operating time of the care piece in a predetermined tooth area.

[0077] The oral care device 100 is generally a device that can clean the oral cavity or detect human features outside the oral cavity. The types of oral care devices 100 include but are not limited to electric toothbrushes, oral scanning devices, endoscopes, or water flossers. In the case where the oral care device 100 is an electric toothbrush, the care piece can be a brush head 30. In the case where the oral care device 100 is an oral scanning device, the care piece can be a protruding structure such as a shell and a light-transmitting lens that protect the internal energy receiving module 40. In the case where the oral care device 100 is a water flosser, the care piece can be a nozzle used by the water flosser to spray liquid or foam outward.

[0078] The following contents of this application specification are mainly explained using an electric toothbrush as an example. It can be understood that the following technical features, the functions corresponding to the technical features, and the technical effects that can be achieved can all be implemented in different types of oral care devices 100.

[0079] In the oral care device 100 of the present application, the energy receiving module 40 is mounted on the core assembly 20 and is located in the handle shell 10, and the energy receiving module 40 located in the handle shell 10 faces the side where the care piece is located to receive at least part of the energy reflected by the care piece and / or the human body features outside the oral cavity. Compared with the solution in which the energy receiving module 40 is arranged outside the handle shell 10, the energy receiving module 40 arranged in the core assembly 20 can be directly electrically connected to other structures of the oral care device 100 in the handle shell 10, and the structure of the oral care device 100 is simple, and the production efficiency is higher.

[0080] The oral care device 100 is further described below with reference to the accompanying drawings.

[0081] See also Figure 2 and Figure 3 In some embodiments, the handle shell 10 is generally a shell structure capable of accommodating a portion of the structure of the oral care device 100. The material of the handle shell 10 includes, but is not limited to, metal, plastic, silicone, or rubber. The handle shell 10 includes a first end 101 and a second end 102 opposite to each other. The care piece is disposed at the first end 101 of the handle shell 10. The structure of the oral care device 100 installed in the handle shell 10 can enter and be installed in the handle shell 10 from the second end 102 of the handle shell 10. The central axis A of the handle shell 10 is an axis that divides the handle shell 10 into two relatively symmetrical parts. When the handle shell 10 is an axisymmetric three-dimensional structure, the central axis A of the handle shell 10 passes through the center of the first end 101 of the handle shell 10 and the center of the second end 102 of the handle shell 10, that is, the extension direction X of the central axis A of the handle shell 10 can be either a straight extension direction from the center of the first end 101 of the handle shell 10 to the center of the second end 102 of the handle shell 10, or a straight extension direction from the center of the second end 102 of the handle shell 10 to the center of the first end 101 of the handle shell 10, which is not limited here. The outer contour shape of the cross section of the handle shell 10 includes but is not limited to a perfect circle, an ellipse, a triangle, a quadrilateral or a pentagon, etc. In some embodiments, along the extension direction X of the central axis A of the handle shell 10, from the second end 102 of the handle shell 10 to the first end 101 of the handle shell 10, the outer contour size of the cross section of the handle shell 10 gradually changes, for example, the outer contour size of the cross section of the handle shell 10 first remains unchanged and then gradually decreases, first increases and then decreases, or changes multiple times. In other embodiments, along the extension direction X of the central axis A of the handle shell 10 , from the second end 102 of the handle shell 10 to the first end 101 of the handle shell 10 , the outer contour size of the cross section of the handle shell 10 remains unchanged.

[0082] Specifically, in some embodiments, the handle shell 10 includes an end shell portion 11 and a peripheral shell portion 13. The end shell portion 11 and the peripheral shell portion 13 are both roughly shell structures with openings 111 on both sides, and the materials of the end shell portion 11 and the peripheral shell portion 13 can be the same or different. In some embodiments, the end shell portion 11 and the peripheral shell portion 13 are integrally formed. In other embodiments, the end shell portion 11 and the peripheral shell portion 13 are separately formed, and the end shell portion 11 and the peripheral shell portion 13 can be connected by non-detachable means such as gluing, hot melt connection or welding, or can be detachably connected by means of threaded connection, snap connection or bolt connection, which is not limited here. The nursing part is arranged at one end of the end shell portion 11, and the energy receiving module 40 is located in the end shell portion 11 and faces the end shell portion 11. The peripheral shell portion 13 is connected to the end shell portion 11 and is arranged at the other end of the end shell portion 11. Compared with the surrounding shell portion 13, the end shell portion 11 is closer to the side where the care piece is located, so that the energy receiving module 40 is arranged in the handle shell 10 and is located at the end of the side closer to the care piece. When the energy receiving module 40 is arranged in the end shell portion 11, the distance between the energy receiving module 40 and the care piece is closer. At this time, the energy reflected by the care piece and / or the human body features outside the oral cavity can enter the energy receiving module 40 more, so that the energy receiving module 40 can obtain more information.

[0083] More specifically, in some embodiments, along the extension direction X of the central axis A of the handle shell 10, the outer contour dimension of the cross section of the end shell portion 11 gradually decreases, so that the end shell portion 11 is roughly a truncated cone or prism structure with a space inside and two opposite ends being flat. Since the end shell portion 11 is roughly a truncated cone or prism structure and the side with a smaller outer contour dimension of the end shell portion 11 is arranged close to the care piece, during the use of the oral care device 100, the liquid and foam flowing down from the care piece are not easy to remain on the outer surface of the end shell portion 11, but will flow along the outer wall of the end shell portion 11 from the side with a smaller outer contour dimension of the end shell portion 11 to the side with a larger outer contour dimension of the end shell portion 11, thereby avoiding liquid and foam from remaining on the surface of the end shell portion 11 and affecting the energy receiving module 40 to receive energy.

[0084] Furthermore, in some embodiments, along the extension direction X of the central axis A of the handle shell 10, the maximum distance between the inner wall of the end shell portion 11 and the energy receiving module 40 on the same straight line is less than 5 mm. The range of energy information acquired by the energy receiving module 40 is roughly a divergent cone angle, so the receiving range of the end closer to the energy receiving module 40 is smaller, and there are fewer structures entering the energy acquisition range of the energy receiving module 40. At the same time, when the area closer to the end of the energy receiving module 40 is blocked, the area where energy information cannot be received is relatively larger, and the obstruction has a greater impact on the range of energy information acquired by the energy receiving module 40. The receiving range of the end farther away from the energy receiving module 40 is larger, and there are more structures entering the energy acquisition range of the energy receiving module 40. At the same time, when the end farther away from the energy receiving module 40 is blocked, the area where energy information cannot be received is relatively small, and the obstruction has a smaller impact on the range of energy information acquired by the energy receiving module 40. When the distance between the energy receiving module 40 and the inner wall of the end shell 11 is greater than 5 mm or equal to 5 mm, the energy receiving module 40 is far away from the inner wall of the end shell 11. At this time, part of the structure connected to the end shell 11 may enter the energy acquisition range of the energy receiving module 40, and the energy receiving module 40 is more likely to be blocked by the structure connected to the end shell 11, affecting the energy receiving module 40's reception of energy. When the distance between the energy receiving module 40 and the inner wall of the end shell 11 is less than 5 mm, the energy receiving module 40 is aligned with the end shell 11, and the range of energy receiving module 40 blocked by structures such as nursing parts is smaller or even not blocked, so the energy receiving module 40 receives more energy and obtains more image information, position information or distance information.

[0085] Furthermore, in some embodiments, along the direction Y perpendicular to and away from the central axis A of the handle shell 10, the distance between the energy receiving module 40 and the handle shell 10 is no more than 3 mm. In some embodiments, the minimum distance between the energy receiving module 40 and the inner wall of the end shell portion 11 is no more than 3 mm. In other embodiments, the minimum distance between the energy receiving module 40 and the inner wall of the peripheral shell portion 13 is no more than 3 mm. Since the energy receiving module 40 is arranged at a position away from the central axis A, and the receiving range of the energy receiving module 40 is roughly a divergent cone angle, when the energy receiving module 40 is arranged at a position as close as possible to the inner wall of the handle shell 10, the main axis of the energy receiving module 40 can be aligned with the apex of the care part. At this time, the energy information on both sides of the hair implantation plate 33 of the care part obtained by the energy receiving module 40 can be relatively symmetrical, and the image information, distance and position information obtained by analysis are also relatively symmetrical. When the distance between the energy receiving module 40 and the handle shell 10 is greater than 3 mm, the energy receiving module 40 is closer to the central axis A of the handle shell 10. At this time, the main axis of the energy receiving module 40 can be parallel to the central axis A of the handle shell 10 or extend in a direction away from the central axis A of the handle shell 10 and intersect with the central axis A of the handle shell 10. At this time, since the energy receiving module 40 can only be offset at the end of the handle shell 10, the receiving range of the energy receiving module 40 will be biased toward one side of the care part, and the energy receiving module 40 is difficult to obtain symmetrical information. When the distance between the energy receiving module 40 and the handle shell 10 is not greater than 3 mm, the energy receiving module 40 is closer to the side of the handle shell 10 away from the central axis A. At this time, the main axis of the energy receiving module 40 can be parallel to the central axis A of the handle shell 10 or extend in a direction close to the central axis A of the handle shell 10 and intersect with the central axis A of the handle shell 10, so that the receiving range of the energy receiving module 40 is centered on the vertex of the care part as much as possible, and the information obtained by the energy receiving module 40 is more symmetrical.

[0086] Furthermore, in some embodiments, the plane where the inner surface of the end shell 11 and the energy receiving module 40 correspond is parallel to the plane where the energy receiving module 40 is located, or the angle between the plane where the inner surface of the end shell 11 and the energy receiving module 40 corresponds is less than 15°. In the case where the two planes opposite to the end shell 11 and the energy receiving module 40 are parallel or the angle is greater than or equal to 15°, the energy receiving range of the energy receiving module 40 may be blocked by the end shell 11 and the partial structure connected to the end shell 11, and the energy receiving module 40 receives less energy, making it difficult to obtain effective image information, position information or distance information, etc. When the two planes opposite to the end shell 11 and the energy receiving module 40 are parallel or the angle between them is less than 15°, the energy receiving range of the energy receiving module 40 is limited to the nursing part and the two sides of the nursing part, and there will be no other structures that will block the information (for example: the output shaft 201 of the driving part 21, the sealing part 70, etc.). At this time, the energy receiving module 40 receives more energy, and the information that the energy receiving module 40 can obtain is more complete.

[0087] Furthermore, in some embodiments, the handle shell 10 is provided with an energy-transmitting area 105 and a non-energy-transmitting area 106, and the energy-transmitting area 105 and the non-energy-transmitting area 106 are connected to each other. In some embodiments, the energy-transmitting area 105 is a shell structure on the handle shell 10 that can transmit energy such as light or electromagnetic waves. The energy-transmitting area 105 can be set in the end shell part 11, or in the surrounding shell part 13, or in the end shell part 11 and the surrounding shell part 13. The energy-transmitting areas 105 set in the end shell part 11 and the surrounding shell part 13 can be connected or separated from each other, which is not limited here. In other embodiments, the energy-transmitting area 105 is a window opened on the handle shell 10, and the surface of the energy-transmitting area 105 is provided with a structure that can seal the gap between the handle shell 10 and the energy receiving module 40 to prevent liquid foam and the like from contacting the energy receiving module 40 through the window. The energy receiving module 40 faces the energy-transmitting area 105 so that the receiving range of the energy receiving module 40 is staggered with the non-energy-transmitting area 106. At least part of the energy reflected by the care piece and / or the human features outside the oral cavity enters the energy receiving module 40 through the energy transmission area 105. On the one hand, the partially light-transmitting handle shell 10 can shield the internal structure of the oral care device 100 through the opaque part, making the appearance of the oral care device 100 more beautiful. At the same time, the partially light-transmitting handle shell 10 can also limit the angle at which at least part of the energy reflected by the care piece and / or the human features outside the oral cavity enters the receiving area of ​​the energy receiving module 40, thereby preventing the energy receiving module 40 from obtaining too much invalid information.

[0088] See also Figure 2 and Figure 4In some embodiments, the core assembly 20 is a component installed in the handle shell 10 and capable of supporting and installing the energy receiving module 40. In some embodiments, the core assembly 20 is detachably installed on the inner wall of the handle shell 10, and the installation method includes but is not limited to threaded connection, snap connection or bolt connection. In other embodiments, the core assembly 20 is non-detachably fixed to the inner wall of the handle shell 10, and the fixing method includes but is not limited to hot melt connection, gluing connection or welding.

[0089] Specifically, in some embodiments, the movement assembly 20 includes a driving member 21, a power supply 23 and a mounting bracket 25. The driving member 21 is generally a driving motor with an output shaft 201. At least part of the structure of the output shaft 201 of the driving member 21 extends from the end shell portion 11 of the handle shell 10 and is connected to the care part. When the driving member 21 is powered on and starts working, the output shaft 201 of the driving member 21 can drive the care part to vibrate to automatically clean the teeth. The power supply 23 is electrically connected to the driving member 21 to supply power to the driving member 21. The mounting bracket 25 is fixed to the handle shell 10, and the driving member 21 and the power supply 23 can be movably mounted on the mounting bracket 25. The energy receiving module 40 is arranged on the mounting bracket 25 and faces the care part. The mounting bracket 25 can be used to install the driving member 21 and the power supply 23 to prevent the driving member 21 and the power supply 23 from shaking in the handle shell 10. The energy receiving module 40 is installed on the mounting bracket 25 to avoid resonance caused by direct contact between the energy receiving module 40 and the driving member 21, and to avoid affecting the energy receiving module 40's reception of at least part of the energy reflected by the care object and / or human body features outside the oral cavity.

[0090] More specifically, in some embodiments, the mounting bracket 25 includes a first mounting shell 251 and a second mounting shell 253 connected to each other, the first mounting shell 251 and the second mounting shell 253 are arranged opposite to each other and form an installation space 2503, at least part of the structure of the driving member 21 is arranged in the installation space 2503, the output shaft 201 of the driving member 21 extends from the first mounting shell 251 and / or the second mounting shell 253 and passes through the end shell 11, and the power supply 23 is installed in the installation space 2503. In some embodiments, the driving member 21 and the power supply 23 are fixedly connected to the first mounting shell 251 and / or the second mounting shell 253. In other embodiments, the driving member 21 and the power supply 23 can move or rotate relative to the first mounting shell 251 and / or the second mounting shell 253 in the installation space 2503. The first mounting shell 251 and the second mounting shell 253 can be used to accommodate and protect the driving member 21, and the first mounting shell 251 and the second mounting shell 253 can also be used to support the energy receiving module 40.

[0091] More specifically, along the direction Y perpendicular to and away from the central axis A of the handle housing 10, the handle housing 10 further includes a first side 103 and a second side 104 opposite to each other. In some embodiments, the first mounting shell 251 is located on the side where the first side 103 of the handle housing 10 is located, and the second mounting shell 253 is located on the side where the second side 104 of the handle housing 10 is located. In some embodiments, the energy receiving module 40 is disposed in the first mounting shell 251 or the second mounting shell 253 and is located outside the mounting space 2503. In other embodiments, the energy receiving module 40 is disposed at the junction of the first mounting shell 251 and the second mounting shell 253 and is located outside the mounting space 2503. Taking the energy receiving module 40 disposed on the second mounting shell 253 as an example, the first mounting shell 251 and the second mounting shell 253 disposed relatively to each other along the direction Y perpendicular to and away from the central axis A of the handle shell 10 can form a larger space between the inner wall of the first side 103 of the handle shell 10 and the first mounting shell 251, and between the inner wall of the second side 104 of the handle shell 10 and the second mounting shell 253. At this time, there is also a larger gap between the energy receiving module 40 disposed on the first mounting shell 251 and / or the second mounting shell 253 and the inner wall of the second side 104 of the handle shell 10. The setting of the gap can avoid squeezing or collision between the handle shell 10 and the energy receiving module 40, so as to protect the energy receiving module 40. In other embodiments, the first mounting shell 251 and the second mounting shell 253 are roughly cylindrical structures with an opening 111 at one end. Along the extension direction X of the central axis A of the handle shell 10, in some embodiments, the first mounting shell 251 is sleeved on the side of the driving member 21 close to the care part, the output shaft 201 of the driving member 21 passes through the first mounting shell 251, the second mounting shell 253 is sleeved on the side of the driving member 21 away from the care part, and the energy receiving module 40 is arranged outside the first mounting shell 251 and close to the side where the care part is located (i.e., located at the end of the handle shell 10). In other embodiments, the second mounting shell 253 is sleeved on the side of the driving member 21 close to the care part, the output shaft 201 of the driving member 21 passes through the second mounting shell 253, the first mounting shell 251 is sleeved on the side of the driving member 21 away from the care part, and the energy receiving module 40 is arranged outside the second mounting shell 253 and close to the side where the care part is located (i.e., located at the end of the handle shell 10). The driving member 21 can be installed in any one of the first mounting shell 251 and the second mounting shell 253. When the driving member 21 is installed in the first mounting shell 251 or the second mounting shell 253, the connection between the driving member 21 and the first mounting shell 251 or the second mounting shell 253 is more stable and not easy to fall off. The energy receiving module 40 is close to the nursing part, and the receiving effect is good.

[0092] Further, in some embodiments, a first guide rail 2511 is provided on the outside of the first mounting shell 251, and a first guide groove corresponding to the first guide rail 2511 is provided on the inner wall of the handle shell 10, and the first guide rail 2511 is used to cooperate with the first guide groove to fix the mounting bracket 25 to the handle shell 10. A second guide rail 2531 is provided on the outside of the second mounting shell 253, and a second guide groove corresponding to the second guide rail 2531 is provided on the inner wall of the handle shell 10, and the second guide rail 2531 is used to cooperate with the second guide groove to fix the mounting bracket 25 to the handle shell 10. When the first mounting shell 251 and the second mounting shell 253 are connected to each other, the driving member 21 and the power supply 23 are both installed in the installation space 2503 and constitute the core assembly 20, the core assembly 20 can slide into the handle shell 10 through the cooperation between the first guide rail 2511 and the first guide groove and / or the cooperation between the second guide rail 2531 and the second guide groove. When the first guide rail 2511 and the second guide rail 2531 are both clamped in the corresponding first guide groove and the second guide groove, the mounting bracket 25 and the handle shell 10 are fixed to each other through the combination of the guide rail and the guide groove without shaking or even rotating, and the connection between the mounting bracket 25 and the handle shell 10 is more stable.

[0093] Furthermore, please combine Figure 5 In some embodiments, the mounting bracket 25 is provided with a mounting portion 255, which protrudes from the outer surface of the mounting bracket 25 and is spaced from the handle shell 10. Compared with the mounting bracket 25, the mounting portion 255 is closer to the inner wall of the handle shell 10; the energy receiving module 40 is arranged on the mounting portion 255 and faces the care piece. In some embodiments, the mounting portion 255 is arranged on the first mounting shell 251 or the second mounting shell 253. When the mounting portion 255 is arranged on the first mounting shell 251, the energy receiving module 40 is located in the gap between the first mounting shell 251 and the inner wall of the first side 103 of the handle shell 10. When the mounting portion 255 is arranged on the second mounting shell 253, the energy receiving module 40 is located in the gap between the second mounting shell 253 and the inner wall of the second side 104 of the handle shell 10. The energy receiving module 40 arranged on the mounting portion 255 can be closer to the side of the oral care device 100 away from the central axis A. On the one hand, the energy receiving module 40 can be more stably installed on the mounting bracket 25 at this time. On the other hand, the energy receiving module 40 can receive energy at a wider viewing angle and will not be excessively blocked by the care parts, so more effective information can be obtained.

[0094] See also Figure 3 and Figure 4In some embodiments, the oral care device 100 further includes a circuit board 50 and a connecting line 60. The circuit board 50 is disposed outside the mounting bracket 25 and is electrically connected to the energy receiving module 40. A control module may be disposed on the circuit board 50, and the control module can send an electrical signal to the energy receiving module 40 to control the opening and closing of the energy receiving module 40. The control module can also receive the electrical signal transmitted to the control module by the energy receiving module 40, so as to analyze the energy information obtained by the energy receiving module 40 to obtain information related to the use of the oral care device 100, such as image information, distance information, and position information. Along the direction Y perpendicular to and away from the central axis A of the handle shell 10, the circuit board 50 and the energy receiving module 40 are respectively disposed on opposite sides of the handle shell 10. In some embodiments, the circuit board 50 is disposed on the first side 103 of the handle shell 10, and the energy receiving module 40 is disposed on the second side 104 of the handle shell 10. In other embodiments, the circuit board 50 is disposed on the second side 104 of the handle shell 10, and the energy receiving module 40 is disposed on the first side 103 of the handle shell 10. One end of the connecting wire 60 is electrically connected to the circuit board 50, and the other end of the connecting wire 60 is electrically connected to the energy receiving module 40. The connecting wire 60 can electrically connect the circuit board 50 and the energy receiving module 40. When the energy receiving module 40 receives external energy, the energy receiving module 40 can convert the received external energy into an electrical signal and transmit the electrical signal to the circuit board 50 and the control module electrically connected to the circuit board 50 via the connecting wire 60, so as to analyze the electrical signal or control the operation mode of the energy receiving module 40.

[0095] Furthermore, please combine Figure 6 In some embodiments, a wire groove 2505 is provided in the mounting bracket 25, and the connecting wire 60 is provided in the wire groove 2505 and is located between the driving member 21 and the inner wall of the wire groove 2505. The wire groove 2505 can be used to fix the connecting wire 60 that passes through the mounting bracket 25. On the one hand, the wire groove 2505 can fix the relative position relationship between the connecting wire 60 and the mounting bracket 25. On the other hand, the wire groove 2505 can also prevent excessive winding and friction between the driving member 21 and the connecting wire 60, thereby avoiding damage to the connecting wire 60. During the installation process, the connecting wire 60 and the driving member 21 can be placed in at least one of the first mounting shell 251 and the second mounting shell 253, and then the other of the first mounting shell 251 and the second mounting shell 253 can be installed. After the first mounting shell 251 and the second mounting shell 253 are assembled into the mounting bracket 25, the energy receiving module 40 is installed to make the installation of the oral care device 100 more convenient.

[0096] Furthermore, in some embodiments, the mounting bracket 25 may be provided with a first threading hole 2501 and a second threading hole 2553, the second threading hole 2553 is communicated with the wire groove 2505, and the first threading hole 2501 is communicated with the mounting space 2503 in the mounting bracket 25. In some embodiments, the first threading hole 2501 and the second threading hole 2553 are respectively located on the first mounting shell 251 and the second mounting shell 253. For example: the first threading hole 2501 is located in the first mounting shell 251 and is opposite to the circuit board 50, and the second threading hole 2553 is located in the second mounting shell 253 and is opposite to the energy receiving module 40. In some examples, the second threading hole 2553 may also be provided in the mounting portion 255 of the second mounting shell 253 and is opposite to the energy receiving module 40. In other embodiments, the first threading hole 2501 and the second threading hole 2553 are both located on the first mounting shell 251 or the second mounting shell 253. The connecting wire 60 electrically connected to the circuit board 50 can pass through the first threading hole 2501 and enter the wire groove 2505. The connecting wire 60 in the wire groove 2505 extends in the wire groove 2505 and passes through the second threading hole 2553 to be electrically connected to the energy receiving module 40, so that the connecting wire 60 passes through the installation space 2503. Compared with the solution in which the connecting wire 60 bypasses the mounting bracket 25, the connecting wire 60 passing through the inside of the mounting bracket 25 can shorten the length required for the connecting wire 60 to connect the circuit board 50 and the energy receiving module 40, and can also prevent the lines from being entangled between the mounting bracket 25 and the handle shell 10, resulting in damage to the connecting wire 60.

[0097] Further, in some embodiments, the mounting portion 255 may be provided with a mounting groove 2551, and along the extension direction X of the central axis A of the handle shell 10, the mounting groove 2551 may be provided at one end of the mounting portion 255 close to the end shell portion 11 and recessed toward the end away from the end shell portion 11, and the energy receiving module 40 can be at least partially accommodated in the mounting groove 2551 and connected to the inner wall of the mounting groove 2551. Along the direction Y perpendicular to and away from the central axis A of the handle shell 10, the mounting groove 2551 can fix the energy receiving module 40 on at least two opposite sides to prevent the energy receiving module 40 from shaking violently relative to the mounting portion 255 when the driving member 21 is running. On the one hand, the mounting groove 2551 can avoid affecting the range of energy acquisition of the energy receiving module 40, resulting in incomplete energy acquisition of the energy receiving module 40, incomplete or erroneous information analyzed. On the other hand, the mounting groove 2551 can also prevent the energy receiving module 40 from falling off from the mounting portion 255, so that the installation of the energy receiving module 40 is more stable.

[0098] Further, in some embodiments, a limiting portion (not shown) may be provided in the handle shell 10, and the limiting portion is generally a structure capable of supporting the mounting bracket 25 and the handle shell 10 respectively. When the movement assembly 20 is installed in the handle shell 10, the mounting bracket 25 and the limiting portion cooperate and abut against each other. When the limiting portion and the mounting bracket 25 abut against each other, the energy receiving module 40 on the mounting bracket 25 can be spaced from the handle shell 10. When the driving member 21 slides slightly in the handle shell 10, the energy receiving module 40 will not be squeezed with the handle shell 10, causing the energy receiving module 40 to be damaged.

[0099] See also Figure 2 and Figure 3 In some embodiments, the care piece is generally a structure that is detachably mounted on the output shaft 21 of the driving member 23. When the oral care device 100 is an electric toothbrush, the care piece may be a brush head 30. When the oral care device 100 is an oral scanning device, the care piece may be a protruding structure such as a housing and a light-transmitting lens that protect the internal energy receiving module 40. When the oral care device 100 is a water flosser, the care piece may be a nozzle of the water flosser for spraying liquid or foam outward.

[0100] Taking an electric toothbrush as an example, the brush head 30 is generally a structure that can be detachably mounted on the output shaft 21 of the driving member 23 and can clean the teeth. When the brush head 30 is mounted on the output shaft 21 of the driving member 23, the central axis A of the brush head 30 coincides with the central axis A of the handle shell 10.

[0101] Specifically, in some embodiments, the care part includes a rod body 31 and a care portion. When the care part is a brush head 30, the care portion includes a hair-implanting plate 33 and bristles 35. Along the extension direction X of the central axis A of the handle shell 10, the rod body 31 includes a first end 311 and a second end 313 opposite to each other. The first end 311 of the rod body 31 is connected to the output shaft 201 of the driving member 21, and the second end 313 of the rod body 31 is connected to the hair-implanting plate 33. In some embodiments, the rod body 31 and the hair-implanting plate 33 are integrally formed. In other embodiments, the rod body 31 and the hair-implanting plate 33 are separately formed. The rod body 31 and the hair-implanting plate 33 can be connected in a detachable manner such as a threaded connection, a snap-fit ​​connection or a bolt connection, or can be connected in a non-detachable manner such as a hot melt connection, a gluing connection or a welding connection, which is not limited here. Along the direction Y perpendicular to and away from the central axis A of the handle shell 10, the bristle plate 33 includes a first side 331 and a second side 333 opposite to each other, the bristles 35 are arranged on the first side 331 of the bristle plate 33 to clean the teeth of the user, and the second side 333 of the bristle plate 33 to the first side 331 of the bristle plate 33 are all located within the receiving range of the energy receiving module 40. In some embodiments, the energy receiving module 40 is located on the side where the second side 333 of the bristle plate 33 is located, and the second side 333 of the bristle plate 33 is the same side as the second side 104 of the handle shell 10. In other embodiments, the energy receiving module 40 is located on the side where the first side 331 of the bristle plate 33 is located, and the first side 331 of the bristle plate 33 is the same side as the first side 103 of the handle shell 10. The energy receiving module 40 can analyze the received energy information to form an image or distance and position information. When the receiving range of the energy receiving module 40 includes the opposite sides of the hair implanting plate 33, the energy receiving module 40 can receive relatively symmetrical information from the opposite sides of the hair implanting plate 33. Therefore, the image information or distance and position information formed after the analysis by the energy receiving module 40 are symmetrically designed, which makes it easier to determine the position of the brush head of the oral care device 100 during use.

[0102] See also Figure 2 and Figure 4In some embodiments, the energy receiving module 40 is roughly a receiver that can receive at least part of the energy reflected by the brush head and / or the human body features outside the oral cavity. Among them, the energy received by the energy receiving module 40 can be emitted by the external environment, and can also be emitted by the energy receiving module 40 and reflected by the brush head and / or the human body features outside the oral cavity. The types of energy that the energy receiving module 40 can receive include but are not limited to sound signals, light signals, electrical signals, and thermal radiation. The types of energy receiving modules 40 include but are not limited to imaging modules, structured light sensors, or time of flight (Time offlight, TOF) sensors. Among them, the imaging module can be a camera module, an ultrasonic imaging module, and an infrared thermal imaging module. The imaging module can directly acquire an image based on the sound waves, light, and thermal radiation reflected by the object. Both the structured light sensor and the TOF sensor can actively emit light to the object and receive the reflected light from the object, so as to measure the flight time of the light, and calculate the distance between each point on the object and the sensor based on the flight time and the propagation speed of the light. When the sensor emits light to an object, the structured light sensor or TOF sensor can measure the positions of multiple points on the object and the distance between each point and the structured light sensor or TOF sensor, and generate a 3D image accordingly. Taking the imaging module as an example, the imaging module faces the brush head and can obtain image information of the brush head and images of human features and / or teeth outside the mouth near the brush head through optical elements such as a camera, and determine the tooth area that the brush head is in contact with at this time based on the relative position between the brush head and the human features and / or teeth outside the mouth, so as to more accurately locate the tooth area.

[0103] Further, in some embodiments, when the oral care device 100 is awakened, the energy receiving module 40 is started or when the energy receiving module 40 is started, and the brush head is adapted according to the image analysis, the oral care device 100 is turned on and started. The awakening method of the oral care device 100 includes but is not limited to button activation, acceleration sensor induction activation, and gyroscope or level induction activation. After the oral care device 100 is awakened, the energy receiving module 40 is started and receives at least part of the energy reflected by the brush head and / or the human body features outside the oral cavity, and obtains the brush head information, the human body feature information outside the oral cavity, and the relative position relationship between the brush head and the human body features outside the oral cavity according to the received part of the energy, so as to accurately determine the current position of the oral care device 100. When the energy receiving module 40 obtains the brush head information and analyzes the adaptation of the brush head, the energy receiving module 40 can send an electrical signal to the control module on the circuit board 50 and automatically start the oral care device 100. On the one hand, it avoids the damage of the oral care device 100 due to the incompatibility of the brush head, and on the other hand, it can also realize the automatic start of the oral care device 100.

[0104] See also Figure 2 and Figure 3In some embodiments, the oral care device 100 further includes a seal 70, the end shell 11 is provided with an opening 111, and the output shaft 201 of the driving member 21 at least partially extends out of the handle shell 10 from the opening 111, and at this time, there is a gap between the inner wall of the opening 111 of the end shell 11 and the output shaft 201 of the driving member 21. The seal 70 is disposed in the handle shell 10 and can be used to seal the gap between the output shaft 201 of the driving member 21 and the inner wall of the opening 111. When the seal 70 is installed at the opening 111, there is also a gap between the portion of the seal 70 located in the end shell 11 and the inner wall of the end shell 11, and the energy receiving module 40 can be disposed in the gap between the seal 70 and the handle shell 10. The material of the seal 70 includes, but is not limited to, elastic and flexible materials such as rubber, silicone or resin. The seal 70 can prevent liquid and foam flowing down from the brush head from entering the handle shell 10 through the gap between the handle shell 10 and the output shaft 201 of the driving member 21 when the oral care device 100 is in working condition. At the same time, it can also prevent water vapor and dust from entering the handle shell 10 when the oral care device 100 is not in working condition, thereby preventing the internal structure of the oral care device 100 from being damp and rusted or causing the internal circuit of the oral care device 100 to short-circuit or even be damaged.

[0105] See also Figure 1 and Figure 4 In some embodiments, the oral care device 100 may further include a prompter 80. The prompter 80 can output different prompt information for different usage scenarios according to the results of image analysis. The prompter 80 outputs prompt information in the following ways: the prompter 80 issues an auditory prompt, a visual prompt, a tactile prompt or an olfactory prompt. Among them, the auditory prompt includes but is not limited to playing abnormal content, rapid music, alarm sounds, etc. through a speaker (not shown in the figure, which can be installed on the oral care device 100) to attract the user's attention. Visual prompts include but are not limited to reminding by displaying abnormal text and abnormal pictures on the display 90 (not shown in the figure, which can be installed on the oral care device 100), or reminding by flashing an indicator light (not shown in the figure, which can be installed on the oral care device 100). Tactile prompts include but are not limited to reminding by vibration feedback issued by a vibrator (not shown in the figure, which can be installed on the oral care device 100). Olfactory prompts include but are not limited to reminding by a special smell emitted by an odor sensor (not shown in the figure, which can be installed on the oral care device 100).

[0106] In some embodiments, when the brush head is found to be incompatible according to the image analysis, the prompter 80 is used to issue a prompt message. The imaging module can obtain the image information of the brush head and obtain relevant information of the brush head, such as the model, production time and service life, etc. according to the obtained image information. When the brush head replaced by the user is incompatible with the oral care device 100, the prompter 80 can prompt the user to replace the correct brush head to avoid damage to the oral care device 100.

[0107] In some embodiments, when the imaging module is working, the prompter 80 is used to issue a prompt message. Since the imaging module can obtain human features and / or tooth images outside the oral cavity near the brush head and analyze and record the image information, when the imaging module is working, the prompter 80 issues a prompt message to remind the user to protect personal privacy in a timely manner.

[0108] In certain embodiments, when it is determined based on image analysis that the operation time of the brush head in the predetermined tooth area is less than a preset time threshold, the prompter 80 is used to issue a prompt message. The imaging module can determine whether the brush head is in the predetermined tooth area at this time based on the positional relationship between the brush head and the human body features outside the oral cavity, and the imaging module can also record the time the brush head stays in the predetermined tooth area and judge the cleaning effect of the brush head in this area accordingly. When the operation time that the brush head stays in the predetermined tooth area is less than the preset time threshold, it can be considered that the cleaning effect performed by the brush head in this area is not good. The prompter 80 can not only record the cleaning effect of each different tooth area, but also promptly prompt the user to extend the time of using the oral care device 100 in the predetermined tooth area.

[0109] In some embodiments, when the image analysis shows that the usage time of the brush head is greater than the preset upper limit, the prompter 80 is used to send a prompt message. Each brush head has a fixed optimal usage time. When a certain brush head is installed on the output shaft 201 of the driving member 21 of the oral care device 100, the imaging module can record the installation time of a certain brush head and start recording the usage time of the brush head. When the usage time of the brush head reaches or exceeds the preset upper limit, the prompter 80 can send a prompt message to the user to prompt the user to replace a new brush head.

[0110] See also Figure 1 and Figure 3 , and combined with Figure 4In some embodiments, the oral care device 100 may further include a display 90, which is disposed on the first side 103 of the handle shell 10 and can be electrically connected to the circuit board 50 and the control module on the circuit board 50. The display 90 can display the relevant information of the brush head obtained by the imaging module and / or the control module after analyzing the image. After the imaging module obtains the image information of the brush head, the imaging module can also convert the obtained information into an electrical signal and transmit it to the circuit board 50 and the control module electrically connected to the imaging module. The control module can obtain the relevant information of the brush head according to the obtained electrical signal, and transmit the relevant information of the brush head to the display 90 in the form of an electrical signal for display, so that the user can confirm the use of the oral care device 100 in time.

[0111] In some embodiments, the oral care device 100 includes an electric toothbrush and an oral scanning device. The oral care device can clean the oral cavity and determine the relevant information of the care parts by identifying the care parts information, and the electric toothbrush and the oral scanning device and other devices with oral care functions can identify the human body feature information and care parts information outside the oral cavity, on the one hand, determine the positional relationship between the part of the device extending into the oral cavity and the tooth area, and on the other hand, can also detect the situation in the oral cavity.
