Abstract
Description
Technical Field
[0001] This utility model relates to the field of oral care, and more particularly to oral care devices. Background Technology
[0002] Electric toothbrushes can clean teeth in the mouth by vibrating on their own. They are highly effective, save time and effort, and have an increasingly broad user base. A wide variety of electric toothbrush products are constantly emerging in the market.
[0003] In related technologies, electric toothbrushes are equipped with cameras to better acquire information about the oral cavity and provide users with more accurate interaction. During the vibration or oscillation of the brush head driven by the motor, the camera is often subjected to significant vibration, causing it to oscillate relative to the brush handle and affecting its imaging quality. The camera may also produce abnormal noises when subjected to resonance; when the camera's vibration reaches its limit, it is also prone to detaching from its previous fixed position and shifting, altering its field of view and further affecting the camera's ability to capture real-time images, thus reducing the user experience. Utility Model Content
[0004] In view of this, the present invention proposes an oral care device, which aims to achieve a stable setting of the imaging module relative to the body and improve the imaging quality of the imaging module during the operation of the motor.
[0005] The oral care device proposed in this utility model includes a handle and a care component. The handle includes: a body comprising a support, a handle shell, a motor, a circuit board, and a battery; a mounting cavity formed within the handle shell, and a light-transmitting opening on the handle shell communicating with the mounting cavity; the support, the circuit board, and the battery being disposed within the mounting cavity; a motor shaft extending outward from the mounting cavity, the motor shaft being used to connect to the care component; a camera module connected to the side of the support near the care component, the light-inlet surface of the camera module facing the light-transmitting opening; electrical connectors of the camera module being electrically connected to the circuit board and the battery respectively; a shock absorber at least partially connected circumferentially to the camera module, the shock absorber avoiding the electrical connectors of the camera module; and the shock absorber being connected between the support and the camera module, and / or, the shock absorber being connected between the handle shell and the camera module.
[0006] As can be seen from the above technical solution, the oral care device proposed in this utility model, by employing a shock-absorbing component at least partially connected around the imaging module, and the shock-absorbing component being located between the imaging module and the handle shell, or between the imaging module and the support, or between the imaging module, handle shell, and support, effectively reduces the vibration and impact force between the imaging module and the support and / or handle shell after the imaging module is mounted on the support, achieving a good shock absorption and vibration isolation effect. Thus, during motor operation, the shock-absorbing component can absorb part of the vibration force transmitted to the imaging module, reducing the vibration of the imaging module and significantly reducing the vibration force on the imaging module, ensuring a stable connection to the support and preventing displacement. Ultimately, this allows the imaging module to always capture real-time images within a preset field of view, providing users with accurate and interactive information. The mounting cavity of this application can accommodate the support and the imaging module. The working environment of the imaging module located within the mounting cavity is relatively sealed, providing a certain degree of dustproof and contamination-proof performance. Sufficient light can pass through the light-transmitting port on the handle shell, enabling the imaging module to normally sense light and form images.
[0007] In some embodiments of this application, the shock absorber is pressed against the space between the handle housing, the shooting module, and the bracket; or, the shock absorber is interference-fitted with the inner wall of the handle housing. Thus, the space between the shooting module and the handle housing is filled with the shock absorber, and after the shock absorber is pressed between the shooting module, the bracket, and the handle housing, the position of the shooting module relative to the bracket and the handle housing is fixed, thereby preventing the shooting module from shaking relative to the handle housing and the bracket when the motor is operating.
[0008] In some embodiments of this application, the shock absorber has an assembly opening, and the lens of the imaging module extends from the assembly opening so that the shock absorber is fitted onto the periphery of the imaging module. The shock absorber has clearance space for the electrical connector to extend. Alternatively, there are multiple shock absorbers spaced apart on the periphery of the imaging module, and the electrical connector is located in the gap between two adjacent shock absorbers. Alternatively, the bracket has a mounting groove, and the imaging module and part of the shock absorber are confined in the mounting groove. Alternatively, the side of the shock absorber near the light-transmitting opening is higher than the highest point of the lens surface of the imaging module, or the side of the shock absorber near the light-transmitting opening is flush with the highest point of the lens surface of the imaging module. Alternatively, the side of the bracket near the light-transmitting opening is higher than the highest point of the lens surface of the imaging module, or the side of the bracket near the light-transmitting opening is flush with the highest point of the lens surface of the imaging module. By defining the specific connection structure between the shock absorber and the shooting module, the shock absorber is kept constantly around the shooting module, thus providing better shock absorption and isolation, improving the shooting quality, and without affecting the electrical connections of the shooting module. After the shooting module is connected to the shock absorber, the side of the shock absorber near the light-transmitting opening contacts the handle shell first, making the lens of the shooting module less prone to scratches; after the shooting module is mounted on the bracket, the side of the bracket near the light-transmitting opening contacts the handle shell first, making the lens of the shooting module less prone to scratches.
[0009] In some embodiments of this application, the shock-absorbing component is a soft rubber component or a foam component. Both of these materials have a certain degree of resilience, thereby providing better shock absorption for the imaging module.
[0010] In some embodiments of this application, the shooting module is interference-fitted, bonded, or detachably fitted to the bracket. The connection method between the shooting module and the bracket can be flexibly selected as needed. Ultimately, the shooting module is fixed on the bracket and aligned with the area to be shot.
[0011] In a further embodiment of this application, the bracket is provided with a mounting slot, and the shooting module is connected in the mounting slot. The mounting slot not only limits the shooting module's position but also, to a certain extent, positions the shooting module's assembly location, preventing it from easily wobbling after installation.
[0012] In a further embodiment of this application, the mounting groove has a first side close to the axis of the motor shaft and a second side away from the axis of the motor shaft. From the first side to the second side, the mounting groove is inclined downwards relative to the motor shaft, with the end of the motor shaft extending out of the handle housing considered upper, and the end of the motor shaft located within the handle housing considered lower. When the mounting groove is inclined relative to the motor shaft, the imaging module connected in the mounting groove is also inclined relative to the motor shaft, allowing for more flexible setting of the imaging area of the imaging module.
[0013] In a further embodiment of this application, a channel is provided on the second side wall of the mounting groove. The electrical connector of the shooting module passes through the channel and enters the mounting cavity. The circuit board and the electrical connector are connected by wires, and the battery is also connected to the electrical connector by wires. This facilitates reliable electrical connection while the bracket secures the shooting module. The electrical connection between the circuit board and the shooting module enables control of the shooting module and the processing and analysis of the shooting information. The electrical connection between the battery and the shooting module provides the necessary power for the shooting module to operate.
[0014] In a further embodiment of this application, at least two oppositely disposed groove walls of the mounting groove limit the shooting module; or, the cross-section of the mounting groove is square, and the groove walls on three sides of the mounting groove limit the shooting module. By setting the shape of the mounting groove, the mounting groove can limit multiple faces of the shooting module, thereby reliably fixing the shooting module.
[0015] In a further embodiment of this application, the mounting groove includes a first groove and a second groove that are connected to each other. The cross-section of the first groove is larger than that of the second groove. The shock absorber is sleeved around the circumference of the shooting module. The groove wall of the first groove is in a limiting fit with the circumferential wall of the shock absorber; the groove wall of the second groove is in a limiting fit with the circumferential wall of the shooting module. That is to say, the mounting groove of this application is stepped, and the shock absorber and the shooting module can be confined in different positions in the mounting groove, thereby achieving the fixation of the shock absorber and the shooting module relative to the bracket, which is convenient for installation; it also enables the shock absorber to effectively dampen the shooting module, and the shock absorber can also play a certain protective role for the shooting module.
[0016] In a further embodiment of this application, the bottom wall of the shock absorber is fitted to the bottom wall of the first groove, and a channel is formed on the side wall of the second groove away from the motor shaft. The electrical connector of the imaging module passes through the channel and enters the mounting cavity. By forming a channel on the side wall away from the motor shaft, it is convenient for the imaging module to connect to the battery or circuit board via wiring, facilitating manual assembly. When this side wall is located on the lower side of the mounting groove, it also saves wiring length.
[0017] In some embodiments of this application, the nearest vertical distance between the edge of the imaging module and the axis of the motor shaft is greater than or equal to 4 mm. Maintaining a certain distance between the imaging module and the motor shaft reduces the vibration intensity experienced by the imaging module.
[0018] In a further embodiment of this application, the oral care device further includes a light-transmitting element that seals the light-transmitting opening. The light-transmitting element not only allows light to pass through the opening to reach the imaging module and enable normal photosensitive imaging, but also seals the opening, preventing external dust and moisture from entering the mounting cavity and creating a better working environment for the imaging module.
[0019] In a further embodiment of this application, the vertical distance between the bottom surface of the light-transmitting element, facing the lowest point near the imaging module, and the lens surface of the imaging module is greater than or equal to 0.8 mm and less than or equal to 3 mm. This ensures that the imaging of the imaging module meets the requirements.
[0020] In a further embodiment of this application, the light-transmitting aperture has an optical axis. On the same cross-section perpendicular to the optical axis, the distance between the two nearest points of the outline of the light-transmitting aperture is greater than or equal to the distance between the two farthest points on the edge region of the field of view of the imaging module. This ensures that the light-transmitting aperture does not obstruct the field of view of the imaging module, thus guaranteeing the imaging effect of the imaging module.

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.
[0051] Where there is no conflict, the following embodiments and features can be combined with each other.
[0052] like Figure 1 As shown, embodiments of this application propose an oral care device in which the handle 100 provides the power required for vibration or oscillation of the care device, enabling it to achieve efficient cleaning of teeth. The care device can be, for example,... Figure 10 The brush head 200 shown can also be a rinsing unit or a rinsing integrated unit; the oral care device can be Figure 10 The electric toothbrush 1000 shown can also be a water flosser, a dental cleaning device, or an oral endoscope. In this application, the electric toothbrush 1000 is used as the oral care device and the brush head 200 is used as the care component for illustration.
[0053] An electric toothbrush 1000 according to an embodiment of this application is an oral care device, combined with... Figure 6 and Figure 10 As shown, it includes a brush head 200 (brush head 200 is a type of care product) and a handle 100;
[0054] Combination Figure 1 and Figure 2 As shown, the handle 100 includes: body 10, shooting module 30 and shock absorber 40.
[0055] Among them, combined Figure 2 and Figure 4 As shown, the main body 10 includes a bracket 15, a handle housing 13, a motor 14, a circuit board 16, and a battery 17. A mounting cavity 11 is formed within the handle housing 13. Figure 2 and Figure 6 As shown, a light-transmitting opening 12 is provided on the handle housing 13, and the light-transmitting opening 12 communicates with the mounting cavity 11. It should be noted that the mounting cavity 11 is located in a relatively closed space inside the body 10, and has a certain accommodating space to facilitate the arrangement of various electronic components or the setting of mounting structures inside.
[0056] Combination Figure 2 and Figure 4 As shown, the motor shaft 141 of the motor 14 extends outward from the mounting cavity 11, and the motor shaft 141 is used to connect... Figure 10 The brush head 200 shown in the figure is such that when the motor 14 is working, the motor shaft 141 drives the brush head 200 connected thereto to swing and / or vibrate.
[0057] Furthermore, combined Figure 2 and Figure 3 As shown, the bracket 15, circuit board 16, and battery 17 are housed in the mounting cavity 11. The shooting module 30 is connected to the side of the bracket 15 near the brush head 200, as shown. Figure 2 and Figure 6 As shown, the light-inlet surface of the imaging module 30 faces the light-transmitting port 12. That is, the mounting cavity 11 can accommodate the bracket 15 and the imaging module 30. The bracket 15 can be entirely housed within the mounting cavity 11, making it invisible from the outside of the handle housing 13. The imaging module 30, connected to the bracket 15, can also be arranged within the mounting cavity 11 along with the bracket 15. The electrical connectors 33 of the imaging module 30 are electrically connected to the circuit board 16 and the battery 17, respectively. The circuit board 16 is electrically connected to the imaging module 30, enabling control of the imaging module 30 and the processing and analysis of the imaging information captured by the imaging module 30. The battery 17 is electrically connected to the imaging module 30, providing the necessary power for the imaging module 30 to operate.
[0058] Furthermore, such as Figure 2 and Figure 3 As shown, the shock absorber 40 is at least partially connected to the circumference of the imaging module 30, and the shock absorber 40 avoids the electrical connector 33 of the imaging module 30. Therefore, the imaging module 30 and the shock absorber 40 can at least partially make contact, so that the shock absorber 40 can provide a certain degree of protection and shock absorption for the imaging module 30.
[0059] like Figure 3 As shown, the shock absorber 40 is connected between the bracket 15 and the imaging module 30; and / or, as Figure 6 As shown, the shock absorber 40 is connected between the handle housing 13 and the shooting module 30.
[0060] As can be seen from the above technical solution, the electric toothbrush 1000 proposed in this utility model, by using a shock-absorbing component 40 that is at least partially connected to the circumference of the shooting module 30, has a certain shock-absorbing and buffering effect with the surrounding environment components after the shooting module 30 is installed on the bracket 15.
[0061] Specifically, during the operation of the motor 14, the motor shaft 141 drives the brush head 200 connected to it to vibrate and / or swing. The shock absorber 40 can absorb part of the vibration force transmitted to the shooting module 30, thereby reducing the vibration of the shooting module 30. At the same time, the shock absorber 40 covers the shooting module 30. Even if the shooting module 30 covered by the shock absorber 40 has a slight vibration, the shock absorber 40 can contact the surrounding environment first. The rebound force of the shock absorber 40 can offset the slight vibration of the shooting module 30, so that the shooting module 30 and the surrounding components can always be kept in the proper position.
[0062] When the shock absorber 40 is connected between the bracket 15 and the shooting module 30, the shock absorber 40 can fill the gap between the bracket 15 and the shooting module 30. After the shooting module 30 is connected to the bracket 15, the shock absorber 40 can reduce the vibration force that may occur between the bracket 15 and the shooting module 30. This results in a larger contact area between the shooting module 30 and the bracket 15, a more stable relative position between the shooting module 30 and the bracket 15, and improved shooting quality of the shooting module 30.
[0063] In the case where the shock absorber 40 is connected between the handle shell 13 and the shooting module 30, the shock absorber 40 is located between the shooting module 30 and the handle shell 13, so that the shock absorber 40 can fill the gap between the shooting module 30 and the handle shell 13. Since the shock absorber 40 is connected to the bracket 15, the shock absorber 40 and the bracket 15 may vibrate relative to the handle shell 13 during the operation of the motor 14. By setting the shock absorber 40 between the shooting module 30 and the handle shell 13, the vibration between the shooting module 30 and the handle shell 13 can be effectively blocked, and the position between the shooting module 30 and the handle shell 13 is more fixed, thereby improving the shooting quality of the shooting module 30.
[0064] When the shock absorber 40 is positioned between the shooting module 30, the handle shell 13, and the bracket 15, the shock absorber 40 can fill the gaps between the shooting module 30 and the handle shell 13, between the shooting module 30 and the bracket 15, and between the bracket 15 and the handle shell 13. This allows the handle shell 13, the bracket 15, and the shooting module 30 to form a relatively stable relative positional relationship. The shock absorber 40 can effectively reduce the vibration and impact force between the shooting module 30 and the bracket 15 or the handle shell 13, achieving good shock absorption and isolation effects, ultimately improving the imaging clarity and shooting quality of the shooting module 30. In this application, the shock absorber 40 does not affect the electrical connection between the shooting module 30 and the battery 17, or between the shooting module 30 and the circuit board 16, thus ensuring that the shooting module 30 can work normally and transmit data back to the circuit board 16.
[0065] Therefore, the above-mentioned technical solution of this application can significantly reduce the vibration force on the shooting module 30, so that the shooting module 30 is stably connected to the bracket 15 and is not easily displaced. Ultimately, the shooting module 30 can always shoot real-time images within the preset field of view, providing users with accurate and interactive information.
[0066] Furthermore, the imaging module 30, located within the mounting cavity 11, operates in a relatively enclosed environment, providing a certain degree of dust and dirt protection. Sufficient light can pass through the light-transmitting opening 12 on the handle 13, enabling the imaging module 30 to properly capture images. The electric toothbrush 1000 of this application, particularly the handle 100, exhibits good overall integrity, and the handle 13 is easy to process.
[0067] Understandably, compared to related technologies where electric toothbrushes experience strong camera vibration during operation, resulting in poor image quality and shooting effects, and are prone to displacement and alteration of the field of view, the handle 100 and the electric toothbrush 1000 with the handle 100 in this application ensure that the shooting module 30 is fixed in position relative to the body 10, and that the shooting module 30 experiences minimal vibration during motor 14 operation, maintaining good shooting quality and effects, and providing users with accurate and interactive information. The circuit board 16 and electrical connector 33 of this application can be connected via wires. The circuit board 16 can provide control commands to the shooting module 30, and can also receive, process, and analyze electrical signals transmitted from the shooting module 30 (such as the electrical signal corresponding to the captured image), thereby generating information for user decision-making. The battery 17 and electrical connector 33 are connected via wires. The wires are relatively flexible and can adapt to different installation spaces, extending freely within the installation space.
[0068] In some embodiments of this application, combined with Figure 3 , Figure 4 and Figure 6As shown, the shock absorber 40 is pressed into the space between the handle housing 13, the shooting module 30, and the bracket 15. In these examples, the shock absorber 40 has a certain contact surface with the shooting module 30, the bracket 15, and the handle housing 13. When the shooting module 30 is subjected to external force (such as vibration), the shock absorber 40 can quickly disperse the external force, effectively reducing the vibration of the shock absorber 40. In specific examples, the space between the shooting module 30 and the handle housing 13 is completely filled by the shock absorber 40, making the position of the shooting module 30 relative to the handle housing 13 relatively fixed. When the motor 14 is working, the shooting module 30 does not shake relative to the handle housing 13 and the bracket 15, making the shooting module 30 more stable during shooting operations.
[0069] In some examples, the shock absorber 40 is interference-fitted with the inner wall of the handle housing 13. This ensures a tight fit between the shock absorber 40 and the handle housing 13, preventing the shock absorber 40 from shifting under continuous vibration. The force transmitted from the motor shaft 141 is isolated by the shock absorber 40 as it passes through the handle housing 13, significantly reducing the vibration force acting on the shooting module 30. Furthermore, the shooting module 30 remains stable relative to the handle housing 13 even when the motor 14 is operating, preventing resonance between the two and improving the shooting quality. In some specific examples, the interference fit between the shock absorber 40 and the inner wall of the handle housing 13 is less than or equal to 0.5 mm, such as 0 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm.
[0070] In other examples, by placing a shock absorber 40 between the bracket 15 and the motor 14, the impact of the vibration generated by the motor 14 during operation on the bracket 15 is minimized, thereby reducing the vibration force transmitted to the shooting module 30.
[0071] In some embodiments of this application, such as Figure 3 As shown, the shock absorber 40 is provided with an assembly port 41, such as Figure 2 As shown, the lens 34 of the imaging module 30 extends from the mounting port 41, allowing the shock absorber 40 to be fitted around the periphery of the imaging module 30. The shock absorber 40 has clearance space for the protruding power supply connector 33. In these examples, the mounting port 41 not only provides the necessary space for the lens 34 to view and capture images, but also allows for assembly and mating with the lens 34, positioning the entire shock absorber 40 around the imaging module 30, thus providing some protection and vibration isolation for the imaging module 30. The clearance space of the shock absorber 40 also allows the power connector 33 sufficient space to electrically connect to the battery 17 and circuit board 16 in the mounting cavity 11.
[0072] In some embodiments, multiple shock absorbers 40 are provided, spaced apart around the periphery of the imaging module 30, and the electrical connector 33 is disposed in the gap between two adjacent shock absorbers 40. By providing multiple shock absorbers 40, different arrangement spaces around the imaging module 30 can be adapted, and the structure of the shock absorbers 40 can be designed in a targeted manner, thereby flexibly arranging the shock absorbers 40, making better use of the space around the imaging module 30, achieving the effect of vibration isolation and damping for the entire imaging module 30, and facilitating the extension of the electrical connector 33 to the circuit board 16 and the battery 17 by the imaging module 30.
[0073] In some embodiments, such as Figure 4 As shown, the bracket 15 is provided with a mounting groove 151, which is combined with Figure 2 and Figure 3 As shown, the imaging module 30 and part of the shock absorber 40 are confined in the mounting groove 151. In these examples, by defining the specific connection structure between the bracket 15 and the imaging module 30 and the shock absorber 40, the shock absorber 40 and the imaging module 30 can be stably confined in the mounting groove 151, thereby fixing the relative positions of the three, making it less likely for the imaging module 30 to shake relative to the bracket 15, and enabling the shock absorber 40 to better dampen and isolate the imaging module 30.
[0074] In some embodiments, reference Figure 4 and Figure 7 As shown, the side of the shock absorber 40 near the light-transmitting opening 12 is higher than the highest point of the lens 32 surface of the imaging module 30, or the side of the shock absorber 40 near the light-transmitting opening 12 is flush with the highest point of the lens 32 surface of the imaging module 30. Therefore, in these embodiments, after the imaging module 30 is connected to the shock absorber 40, the side of the shock absorber 40 near the light-transmitting opening 12 preferentially contacts the handle housing 13, making the lens 32 of the imaging module 30 less prone to scratches.
[0075] In other embodiments, the side of the bracket 15 near the light-transmitting port 12 is higher than the highest point of the lens 32 surface of the imaging module 30, or the side of the bracket 15 near the light-transmitting port 12 is flush with the highest point of the lens 32 surface of the imaging module 30. After the imaging module 30 is assembled onto the bracket 15, the side of the bracket 15 near the light-transmitting port 12 preferentially contacts the handle housing 13, making the lens 32 of the imaging module 30 less prone to scratches.
[0076] In some embodiments of this application, the shock absorber 40 is made of soft rubber or foam. Both types of shock absorbers 40 have a certain degree of resilience and can absorb high energy, thus providing good shock absorption for the imaging module 30. When using foam, due to its loose and porous structure and lightweight nature, it can also play a role in noise reduction and weight reduction; in addition, foam is easy to process and easy to connect to the imaging module 30.
[0077] In some embodiments of this application, the shooting module 30 is interference-fitted with the bracket 15. This allows the shooting module 30 to be stably positioned with the bracket 15, preventing it from easily detaching from the bracket 15 after installation. For example, this can be achieved through the aforementioned mounting groove 151, where the base of the shooting module 30 and the groove wall of the mounting groove 151 achieve an interference fit.
[0078] In some other embodiments of this application, the shooting module 30 is bonded to the bracket 15. For example, adhesive backing or spot adhesive can be applied to the base of the shooting module 30 to achieve bonding between the two.
[0079] In some embodiments of this application, the shooting module 30 and the bracket 15 are detachably coupled. For example, the detachable coupling can be achieved by providing one or more coupling forms such as snap-fit slots, buckle slots, fasteners, and mounting holes. When the shooting module 30 and the bracket 15 are detachably connected, the shooting module 30 can be easily replaced individually, and the shooting module 30 can also be easily removed for cleaning and repair.
[0080] Therefore, the connection method between the shooting module 30 and the bracket 15 can be flexibly selected as needed. Finally, the shooting module 30 is fixed on the bracket 15 and the shooting module 30 is aligned with the area to be shot.
[0081] In further embodiments of this application, such as Figure 4 As shown, the bracket 15 is provided with a mounting slot 151, and the imaging module 30 is connected in the mounting slot 151. In these examples, the mounting slot 151 not only limits the imaging module 30, but also positions the assembly position of the imaging module 30 to a certain extent, so that the imaging module 30 is not easy to shake back and forth after installation.
[0082] In some further embodiments of the application, such as Figure 2 As shown, the mounting groove 151 has a first side close to the axis of the motor shaft 141 and a second side away from the axis of the motor shaft 141. From the first side to the second side, the mounting groove 151 is inclined downwards relative to the motor shaft 141, with the end of the motor shaft 141 extending out of the handle housing 13 considered upper, and the end of the motor shaft 141 located within the handle housing 13 considered lower. When the mounting groove 151 is inclined relative to the motor shaft 141, the imaging module 30 connected to the mounting groove 151 is also inclined relative to the motor shaft 141, allowing for more flexible setting of the imaging area of the imaging module 30.
[0083] In a further embodiment of this application, a channel 1514 is provided on one side wall of the mounting groove 151, through which the electrical connector 33 of the imaging module 30 passes into the mounting cavity 11. The channel 1514 provides the necessary space for the arrangement of the electrical connector 33, facilitating the bracket 15 to secure the imaging module 30 while ensuring a reliable electrical connection.
[0084] In a specific example, the battery 17 and the motor 14 are arranged at intervals along the extension direction of the motor shaft 141, with the motor 14 positioned closer to the direction in which the motor shaft 141 extends. That is, the motor 14 is located in the upper space of the mounting cavity 11, while the battery 17 is located in the lower space of the mounting cavity 11, so that the battery 17 can also provide the necessary power for the motor 14 to operate. In other examples, the battery 17 and the motor 14 may have other relative positions, which are not limited here.
[0085] In some specific embodiments, such as Figure 4 As shown, the bracket 15 includes a first bracket 152 and a second bracket 153, which are respectively located on opposite sides of the motor 14 and are detachably connected. For example, they can be connected by mounting holes and fasteners, or by snap-fit or plug-in connections. Furthermore, the second bracket 153 extends to the lower part of the mounting cavity 11, is connected to the handle housing 13, and can cover the outside of the battery 17. The second bracket 153 can be provided with a first mounting structure supporting the motor 14, a second mounting structure supporting the battery 17, a third mounting structure supporting the shooting module 30, and a fourth mounting structure supporting the circuit board 16, thereby enhancing the functionality of the second bracket 153 and ensuring that the motor 14, battery 17, shooting module 30, and circuit board 16 within the mounting cavity 11 all have corresponding mounting structures and positions, preventing shaking after assembly. In some examples, the circuit board 16 is snapped onto the surface of the second bracket 153 away from the battery 17 and the motor 14, which facilitates the connection of the circuit board 16 to the button on the handle housing 13 and also makes full use of the arrangement space within the mounting cavity 11.
[0086] In some embodiments, multiple brackets 15 are provided, and the multiple brackets 15 are respectively connected to the mounting cavity 11 in the handle housing 13. Each bracket 15 is connected to a shooting module 30, so that the handle 100 of this application has multiple shooting modules 30 capable of capturing real-time external images, especially the images around the brush head 200. In a specific example, such as Figure 4 As shown, the first bracket 152 is provided with a mounting slot 151, and the second bracket 153 is provided with a mounting slot 151 (not shown in the figure). Each mounting slot 151 is limited by a shooting module 30. The shooting module 30 is surrounded by a shock-absorbing component 40, so that multiple shooting modules 30 can shoot the external scene in real time. Each shooting module 30 is stable relative to its respective bracket 15, is not easy to shake, and has high shooting quality.
[0087] In further embodiments of this application, such as Figure 4 and Figure 5As shown, at least two oppositely arranged slot walls of the mounting slot 151 limit the shooting modules 30, for example... Figure 4 The first groove wall 1511 and the third groove wall 1513 in the example; for example Figure 4 The first groove wall 1511, the second groove wall 1512, and the third groove wall 1513 in the mounting groove 151 can limit the positioning of the imaging module 30 from multiple faces, thus stabilizing the mounting position of the imaging module 30 relative to the bracket 15. The two opposing groove walls also provide a certain clamping effect on the imaging module 30, preventing it from wobbling within the mounting groove 151. In a specific example, such as... Figure 4 and Figure 5 As shown, the mounting groove 151 does not have a fourth groove wall, but a channel 1514 is provided on the fourth groove wall to realize the setting of the electrical connector 33 in the aforementioned embodiment.
[0088] In some examples, the cross-section of the mounting slot 151 is square, and the slot walls on three sides of the mounting slot 151 limit the imaging module 30. For example, in a specific embodiment, it can be the aforementioned type. Figure 4 The first groove wall 1511, the second groove wall 1512, and the third groove wall 1513 all limit the shooting module 30. By setting the shape of the mounting groove 151, the mounting groove 151 can limit multiple surfaces of the shooting module 30, thereby reliably fixing the shooting module 30.
[0089] In some specific embodiments, such as Figure 3 and Figure 5 As shown, the mounting slot 151 is configured as two vertically connected first slots 151a and second slots 151b. The cross-section of the first slot 151a is larger than that of the second slot 151b. The base of the shooting module 30 is limited in the second slot 151b, and the shock absorber 40 is limited in the first slot 151a. At the same time, the shock absorber 40 is sleeved around the lens 34 of the shooting module 30. In these examples, the mounting slot 151 can limit the shooting module 30 and the shock absorber 40 respectively, so that the position between the shooting module 30 and the bracket 15 is relatively stable, and the position of the shock absorber 40 is also relatively stable. The position of the shock absorber 40 relative to the shooting module 30 is determined, which is beneficial for the shock absorber 40 to always provide protection and shock absorption for the shooting module 30.
[0090] In some embodiments, combined with Figure 3 and Figure 5The wall of the first groove 151a is matched with the peripheral wall of the shock absorber 40; the wall of the second groove 151b is matched with the peripheral wall of the imaging module 30. In other words, the mounting groove 151 of this application is stepped, and the shock absorber 40 and the imaging module 30 can be confined in different positions within the mounting groove 151, thereby fixing the positions of the shock absorber 40 and the imaging module 30 relative to the bracket 15, facilitating installation; it also allows the shock absorber 40 to effectively dampen the vibration of the imaging module 30, and the shock absorber 40 can also provide a certain degree of protection for the imaging module 30.
[0091] In some further embodiments, combined with Figure 4 and Figure 5 As shown, the bottom wall of the shock absorber 40 is in contact with the bottom wall of the first groove 151a. A channel 1514 is provided on the side wall of the second groove 151b away from the motor shaft 141. The electrical connector 33 of the imaging module 30 passes through the channel 1514 and enters the mounting cavity 11. By providing a channel 1514 on the side wall away from the motor shaft 141, it is convenient for the electrical connector 33 of the imaging module 30 to pass through and connect to the battery 17 or the circuit board 16, which facilitates manual assembly. When this side wall is located on the lower side of the mounting groove 151, it can also save the length of the wiring.
[0092] In some embodiments of this application, the nearest vertical distance between the edge of the imaging module 30 and the axis of the motor shaft 141 is greater than or equal to 4 mm. It is understood that the closer the position is to the motor shaft 141, the higher the vibration energy it receives. This application maintains a certain distance between the imaging module 30 and the motor shaft 141 to reduce the vibration intensity that the imaging module 30 needs to withstand.
[0093] In further embodiments of this application, such as Figure 1 and Figure 2 As shown, the handle 100 of the electric toothbrush 1000 also includes a light-transmitting element 20, which seals the light-transmitting opening 12. The light-transmitting element 20 not only allows light to pass through the light-transmitting opening 12 to reach the imaging module 30 and enable the imaging module 30 to perform normal light-sensing and imaging; the light-transmitting element 20 also seals the light-transmitting opening 12, thus isolating external dust and moisture from the outside of the mounting cavity 11, making the working environment of the imaging module 30 better.
[0094] In some embodiments of this application, such as Figure 2 and Figure 8As shown, the light-transmitting opening 12 includes a first light-transmitting segment 121 and a second light-transmitting segment 122. The first light-transmitting segment 121 connects to the second light-transmitting segment 122. The cross-section of the first light-transmitting segment 121 is larger than that of the second light-transmitting segment 122. The light-transmitting element 20 is connected to the first light-transmitting segment 121 and seals the second light-transmitting segment 122. The imaging module 30 is positioned close to the second light-transmitting segment 122. In these examples, the light-transmitting opening 12 has a certain depth. The first light-transmitting segment 121 is located at the position connecting to the external environment, while the second light-transmitting segment 122 is located at the position connecting to the mounting cavity 11. For the connection between the first light-transmitting segment 121 and the second light-transmitting segment 122 with different cross-sections, a certain stepped transition structure can be formed. Therefore, the side of the second light-transmitting segment 122 facing the first light-transmitting segment 121 can also serve as the side of the first light-transmitting segment 121, and this side can be used to install the light-transmitting element 20. The light-transmitting element 20 is located in the first light-transmitting section 121 with a larger cross-section. The light-transmitting element 20 is not easy to slip out of the second light-transmitting section 122 with a smaller cross-section. This not only makes it easy to fix the light-transmitting element 20, but also allows the light-transmitting element 20 to completely block the second light-transmitting section 122 with a smaller cross-section, providing the necessary structural foundation for the design of the light-transmitting element 20 to be embedded in the first light-transmitting section 121. Since the overall size of the imaging module 30 is larger than that of the second light-transmitting segment 122, the imaging module 30 can be positioned close to the second light-transmitting segment 122, but the imaging module 30 will not be completely enclosed within the second light-transmitting segment 122. Therefore, for a lens 32 with a certain curvature, the closest distance between the imaging module 30 and the second light-transmitting segment 122 is such that part of the lens 32 extends into the second light-transmitting segment 122. However, for a lens 32 with a flat cross-section, the closest distance between the imaging module 30 and the second light-transmitting segment 122 is such that the gap between the lens 32 and the bottom surface of the second light-transmitting segment 122 is minimized, at which point the lens 32 will not extend into the second light-transmitting segment 122. Therefore, the light-facing surface of the lens 32 in this application will maintain a certain distance from the bottom surface of the light-transmitting element 20 located in the first light-transmitting segment 121.
[0095] In some specific embodiments of this application, such as Figure 1 As shown, the light-transmitting port 12 has an optical axis 120, combined with Figure 1 , Figure 2 and Figure 8As shown, the depth of the second light-transmitting segment 122 extending along the optical axis 120 is greater than the depth of the first light-transmitting segment 121 extending along the optical axis 120. In these examples, the second light-transmitting segment 122 is deeper, so that the light-transmitting element 20 is installed after the first light-transmitting segment 121. Since the closest distance that can be set between the imaging module 30 and the second light-transmitting segment 122 is limited (as shown above, it is related to the structure of the lens 32), the imaging module 30 is still outside the light-transmitting opening 12, either entirely or entirely. Therefore, after the imaging module 30 is fixed in position in the mounting cavity 11, the distance between the imaging module 30 and the light-transmitting element 20 has a certain depth, close to the depth of the second light-transmitting segment 122, so that the light from the outside can accurately reach the imaging module 30 after passing through the light-transmitting element 20 and the light-transmitting opening 12, ensuring that the imaging module 30 has a good imaging effect.
[0096] In some embodiments of this application, the highest point of the light-transmitting element 20 facing away from the shooting module 30 does not extend beyond the surface of the body 10. In these examples, the light-transmitting element 20 is designed to be embedded in the first light-transmitting segment 121, and the top of the light-transmitting element 20 does not protrude outward. The arrangement of the light-transmitting element 20 does not affect the appearance structure of the body 10, thus ensuring good integrity of the handle 100.
[0097] In a further embodiment of this application, the vertical distance between the lowest point of the bottom surface of the light-transmitting element 20 facing near the imaging module 30 and the surface where the lens 32 of the imaging module 30 is located is greater than or equal to 0.8 mm and less than or equal to 3 mm. This ensures that the imaging of the imaging module 30 meets the requirements. For example, the vertical distance between the lowest point of the bottom surface of the light-transmitting element 20 facing near the imaging module 30 and the lens 32 of the imaging module 30 is 0.8 mm, 0.9 mm, 1.0 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2.0 mm, 2.3 mm, 2.5 mm, 2.7 mm, or 3 mm, etc., so that the imaging module 30 can receive sufficient light and form an image, and can prevent the imaging module 30 from being too close to the light-transmitting element 20, thus preventing impact when dropped by external force.
[0098] In a further embodiment of this application, the light-transmitting aperture 12 has an optical axis 120. On the same cross-section perpendicular to the optical axis 120, the distance between the two nearest points of the outline of the light-transmitting aperture 12 is greater than or equal to the distance between the two farthest points on the edge region of the field of view of the imaging module 30. This ensures that the light-transmitting aperture 12 does not obstruct the field of view of the imaging module 30, thus guaranteeing the imaging effect of the imaging module 30.
[0099] In some embodiments of this application, the light-transmitting element 20 is bonded to the surface of the body 10 to seal the light-transmitting opening 12. For example, adhesive can be applied to the side of the light-transmitting element 20 facing the light-transmitting opening 12, allowing the light-transmitting element 20 to be adhered to the first light-transmitting segment 121. Alternatively, spot adhesive can be applied to the side of the light-transmitting element 20 facing the light-transmitting opening 12, allowing the light-transmitting element 20 to be adhered to the light-transmitting opening 12, thus saving adhesive usage. In other words, in these embodiments, the light-transmitting element 20 and the handle shell 13 are separately configured; the light-transmitting element 20 can be assembled independently onto the handle shell 13 and seal the light-transmitting opening 12.
[0100] In some other examples in this application, such as Figure 2 As shown, the body 10 includes a handle shell 13, and the light-transmitting element 20 is integrally formed and connected to the handle shell 13. Therefore, after the light-transmitting element 20 and the handle shell 13 are integrally formed, the light-transmitting element 20 and the body 10 can form an integral structure, resulting in a better sealing effect of the light-transmitting opening 12 and a better overall appearance of the body 10. In a specific example, the light-transmitting element 20 can be integrally formed with the handle shell 13 through injection molding, achieving a good seal at the light-transmitting opening 12. This method is convenient for injection molding, has good integrality, is relatively stable for mass production, and results in high consistency of batch products.
[0101] In some embodiments of this application, combined with Figure 6 , Figure 7 and Figure 8 As shown, the body 10 includes a motor 14, with a motor shaft 141 extending outward from the mounting cavity 11. A light-transmitting opening 12 is located on the side of the body 10 facing the motor shaft 141. That is, the light-transmitting opening 12 is positioned as close as possible to the top of the body 10. (Reference) Figure 9 The angle formed by the intersection of the vertical plane of the light-transmitting element 20 and the axis of the motor shaft 141 is α, and α is an acute angle. In other words, the angle formed by the intersection of the plane parallel to the cross-section of the light-transmitting element 20 and the axis of the motor shaft 141 is β, and β is an acute angle. Therefore, it can be seen that the light-transmitting element 20 is installed at an angle on the body 10, which not only facilitates the downward sliding of water droplets falling on the light-transmitting element 20, but also provides a structural basis for the adaptive adjustment of the shooting angle of the shooting module 30.
[0102] In some further examples of this application, such as Figure 9As shown, the light-transmitting element 20 has a first end 21 near the motor shaft 141 and a second end 22 away from the motor shaft 141. From the first end 21 to the second end 22, the light-transmitting element 20 is inclined downwards, with the side of the handle 100 extending from the motor shaft 141 considered upwards and the side of the handle 100 away from the motor shaft 141 considered downwards. It can be understood that the light-transmitting element 20 is designed to be lower in the direction away from the motor shaft 141. Since foam is highly likely to flow down the brush head 200 onto the light-transmitting element 20 during teeth cleaning, the inclined arrangement of the light-transmitting element 20 facilitates the downward sliding of water droplets onto the handle 100, preventing water accumulation on the light-transmitting element 20 and the handle 100. This allows the surface of the light-transmitting element 20 to dry quickly and does not obstruct light from entering through the light-transmitting opening 12.
[0103] In some further examples of this application, the downward tilt angle of the light-transmitting element 20 ranges from 10 degrees to 40 degrees. By controlling the tilt angle of the light-transmitting element 20, the water flowing onto the light-transmitting element 20 can be smoothly allowed to slide down, and the field of view of the imaging module 30 can be kept within a reasonable range. For example, the downward tilt angle of the light-transmitting element 20 can be 10 degrees, 20 degrees, 25 degrees, 30 degrees, or 40 degrees, and can be selected as needed. Figure 9As shown, the downward tilt angle of the light-transmitting element 20 can be understood as the angle formed between the plane containing the light-transmitting element 20 and the plane perpendicular to the motor shaft 141. This angle is the same as angle α, and its sum with angle β is 90 degrees. Therefore, when a smaller tilt angle is selected, such as 10 degrees or 20 degrees, the field of view of the imaging module 30 can be closer to the motor shaft 141, thus covering the brush head 200 on the motor shaft 141 as much as possible. This allows the imaging module 30 to observe real-time information during the teeth cleaning process, facilitating the provision of necessary information for user interaction. When a larger tilt angle is selected, such as 40 degrees or 30 degrees, the field of view of the imaging module 30 is further away from the motor shaft 141, allowing the imaging module 30 to capture more information around the motor shaft 141, such as facial information and environmental information. It should also be noted that in these examples, since the light-transmitting element 20 is located at the light-transmitting opening 12, the optical axis 120 of the light-transmitting opening 12 can also have a certain angle with the motor shaft 141, corresponding to the inclined structure of the light-transmitting element 20. When the optical axis 120 of the light-transmitting opening 12 coincides with the central axis of the light-transmitting element 20, the angle between the optical axis 120 of the light-transmitting opening 12 and the motor shaft 141 can be regarded as the aforementioned angle α. That is to say, the entire light-transmitting opening 12 is also inclined relative to the motor shaft 141, so when the light-transmitting element 20 is installed at the light-transmitting opening 12, it is naturally inclined relative to the motor shaft 141. In some specific examples, the central axis of the photosensitive center of the imaging module 30 coincides with or is parallel to the optical axis 120 of the light-transmitting opening 12. In this case, the imaging module 30 is also inclined relative to the motor shaft 141. It can be seen that by synchronously adjusting the inclination of the light-transmitting element 20, the light-transmitting opening 12, and the imaging module 30, all three can be inclined relative to the motor shaft 141.
[0104] In some embodiments of this application, the outline of the light-transmitting opening 12 is circular, elliptical, square, or irregular. The light-transmitting opening 12 can be processed according to actual needs, making the shape design of the light-transmitting opening 12 more flexible.
[0105] In some embodiments of this application, the thickness of the light-transmitting element 20 is greater than or equal to 0.3 mm and less than or equal to 1.5 mm. For example, the thickness can be 0.3 mm, 0.4 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.4 mm or 1.5 mm, etc., so that the entire light-transmitting element 20 has a certain strength, is easy to assemble, is easy to seal the light-transmitting opening 12, and can also transmit enough light to facilitate the shooting module 30 to enter light and form an image.
[0106] In some embodiments of this application, the light-transmitting element 20 is made of glass or plastic. Both glass and plastic parts have good light transmittance and a certain strength, allowing sufficient light to pass through the light-transmitting element 20 and ensuring sufficient light enters the light-inlet surface of the imaging module 30, thus guaranteeing the required imaging effect. When the light-transmitting element 20 is made of plastic, it is also convenient to integrally mold it with the handle housing 13. Therefore, the light-transmitting element 20 of this application can be integrally molded with the handle housing 13, or it can be separately assembled onto the handle housing 13 to seal the light-transmitting opening 12, as described in the foregoing embodiments.
[0107] In some embodiments of this application, the shooting module 30 is activated and begins operation when the motor 14 of the handle 100 starts working. In other embodiments, the shooting module 30 is activated and begins operation when the handle 100 is picked up by the user from a static standby state and its posture changes. In other examples, the handle 100 is provided with a separate control button to control the shooting module 30 to independently open or close the shooting screen. The activation and deactivation modes of the shooting module 30 can be set according to actual needs, and no limitations are imposed here.
[0108] In this application, the principles and related structures of how the motor 14 drives the brush head 200 to vibrate and / or oscillate are prior art well known to those skilled in the art and will not be described in detail here. Similarly, the principles and related structures of how the shooting module 30 captures images of the external environment are also prior art well known to those skilled in the art and will not be described in detail here.
[0109] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
