Description

Technical Field

[0001] This invention relates to the field of smart toothbrush technology, and more particularly to a smart toothbrush with an openable and foldable brush head. Background Technology

[0002] With continuous technological advancements, the electric toothbrush industry has matured, and electric toothbrushes, due to their superior cleaning capabilities, are gradually replacing ordinary manual toothbrushes. Ordinary toothbrushes rely heavily on the user's brushing pressure and are less flexible, making it difficult to control the brushing direction and resulting in inadequate cleaning. Electric toothbrushes, on the other hand, allow users to adjust the brushing pressure and angle according to their needs, a more scientific and user-friendly design. Furthermore, the smaller brush heads used in electric toothbrushes effectively clean between teeth and areas that ordinary toothbrushes cannot reach, thus improving the cleaning effect and enhancing the user experience.

[0003] However, while electric toothbrushes improve cleaning power, they cannot effectively prevent or detect various oral problems such as cavities, tooth decay, receding gums, plaque, and food residue. Therefore, some visual toothbrushes have emerged on the market, allowing users to monitor their oral health while brushing. However, these visual toothbrushes typically have a perforated brush head to serve as a camera channel, with the camera mounted at the back of the brush head to capture images of the mouth. This design, while prioritizing imaging, sacrifices the area of ​​the bristles embedded, resulting in a cleaning ability that falls short of expectations.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Summary of the Invention

[0005] The purpose of this invention is to provide a smart toothbrush with an openable and foldable brush head that can meet the user's needs for taking pictures of the oral cavity while taking into account the bristle area, thereby greatly improving the user experience.

[0006] The technical solution provided by this invention is as follows: A smart toothbrush with an openable / closable brush head includes: Brush head assembly, including brush handle and bristles; The bristles are inserted into the end of the brush handle, and the brush handle has a slit along its center line, the slit separating the bristles into a first segment and a second segment; The main unit has a power output end for mounting the brush rod; A camera assembly includes a support arm and a camera. The support arm is mounted on the power output end to fix the camera to the back of the bristles and to the position corresponding to the gap. An adjustment component is used to adjust the opening degree of the slit, so that the camera is exposed between the first section and the second section to obtain oral cavity information, and to hide the camera on the back of the bristles.

[0007] In some embodiments, the slit extends from one end of the brush rod into which the bristles are inserted toward the other end of the brush rod, and does not penetrate to the end of the brush rod away from the bristles, thus forming a first support, a second support, and a connecting body; and The connecting body enables the first support rod and the second support rod to open and close under the action of the adjusting component; The first section and the second section are respectively implanted into the first support rod and the second support rod at one end away from the connecting body.

[0008] In some embodiments, the main unit includes a brush handle and a motor disposed inside the brush handle; The drive shaft of the motor extends from inside the brush handle to the outside of the power output end; The connecting body has a socket at the end away from the brush bristles for inserting the drive shaft.

[0009] In some embodiments, the adjusting assembly includes an operating element, a connecting rod, and a pin; The operating element is mounted on the brush handle; The pin is installed on the support arm and is fitted into the gap; The brush handle has a slide that connects to the support arm. The connecting rod is slidably disposed within the slide rail, with one end of the connecting rod connected to the operating member and the other end connected to the pin. The operating member can operably drive the connecting rod to slide back and forth along the slide rail, thereby driving the pin to slide back and forth along the gap, thereby adjusting the opening degree of the gap.

[0010] In some embodiments, the brush rod has a mating surface and the support arm has a mating surface; When the brush rod is installed on the power output end, the mating surface and the mating surface are arranged opposite to each other, and a gap is preset between the mating surface and the mating surface; The mating surface has a groove corresponding to the position of the gap, which is connected to the slide. The pin is located in the groove and slides relative to the groove under the drive of the connecting rod.

[0011] In some embodiments, the gap is provided with a receiving hole; The operating component is operably driven to slide the pin along the gap. When the pin is located in the receiving hole, the first support rod and the second support rod move closer together to retract due to the release of the pin, so as to hide the camera on the back of the bristles. As the pin slides toward the receiving hole away from the bristles, the angle between the first support rod and the second support rod gradually increases, so that the camera is exposed between the first section and the second section.

[0012] In some embodiments, the junction between the receiving hole and the gap is rounded.

[0013] In some embodiments, the operating element includes an operating portion and a connecting portion mounted on the operating portion; and The brush handle has a track on its side wall; The operating part is slidably connected to the track, and the connecting part extends through the track into the inside of the brush handle to engage with the connecting rod.

[0014] In some embodiments, the host component further includes a main control board, a data processing and transmission module, a battery, and a switch button that are electrically connected to each other; The main control board, the data processing and transmission module, and the battery are installed inside the brush handle; The switch button is installed on the side wall of the brush handle; and The camera is electrically connected to the main control board, which controls the camera to collect oral cavity information. The data processing and transmission module transmits the acquired oral cavity information to the terminal device in real time for the user to view.

[0015] In some embodiments, the camera assembly further includes a lighting source; The lighting source is installed on the support arm and is positioned adjacent to the camera; The lighting source is electrically connected to the main control board, which controls the lighting source to illuminate the oral cavity, thereby assisting the camera in collecting oral cavity information.

[0016] In some embodiments, the support arm and the brush handle are integrally formed.

[0017] In some embodiments, the brush handle is made of a resilient material.

[0018] The technical effects of this invention are as follows: In this patent, a slit is created at the center line of the brush handle, dividing the bristles into symmetrical first and second sections. An adjustment component allows for adjustment of the slit's opening degree, enabling the first and second sections to come closer together, concealing the camera behind the bristles and preventing damage during brushing. When the user wants to obtain oral cavity information, they simply operate the adjustment component again to separate the first and second sections, changing the angle between the first and second supports to expose the camera between them for photographing or video recording the user's mouth. This design avoids sacrificing bristle area for light transmission, satisfying the user's need to photograph the mouth while maintaining sufficient bristle area, and effectively ensuring the amount of bristles implanted meets ideal cleaning requirements, thus significantly improving the user experience.

Detailed Implementation

[0021] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0022] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0023] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0024] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] According to a specific embodiment provided by the present invention, such as Figures 1 to 10As shown, a smart toothbrush with an openable / closable brush head may include a brush head assembly 100, a main unit assembly 200, a camera assembly 300, and an adjustment assembly 400. The brush head assembly 100 includes a brush handle 110 and bristles 120. The bristles 120 are inserted into the end of the brush handle 110, which has a slit 111 along its centerline, separating the bristles 120 into a first segment 121 and a second segment 122. The main unit assembly 200 has a power output end 210 for mounting the brush handle 110. The camera assembly 300 includes an arm 310 and a camera 320. The arm 310 is mounted on the power output end 210 to fix the camera 320 to the back of the bristles 120, corresponding to the position of the slit 111. The adjustment component 400 is used to adjust the opening degree of the slit 111, so that the camera 320 is exposed between the first section 121 and the second section 122 to obtain oral cavity information, and to hide the camera 320 behind the bristles 120.

[0027] In this embodiment, by creating a slit 111 at the center line of the brush handle 110, the bristles 120 can be divided into symmetrical first segments 121 and second segments 122. The opening and closing degree of the slit 111 can be adjusted by setting an adjustment component 400, which can be used to bring the first segments 121 and second segments 122 of the bristles 120 closer together, thus hiding the camera 320 behind the bristles 120 and preventing damage to the camera 320 during brushing. When the user wants to obtain oral cavity information, they only need to operate the adjustment component 400 again to separate the first segments 121 and second segments 122 of the bristles 120. When the slit 111 between the first segments 121 and second segments 122 is large enough, the camera 320 can be exposed between the first segments 121 and second segments 122 to take pictures or videos of the user's oral cavity. This setup avoids sacrificing the area of ​​the bristles 120 as a light transmission channel, while still taking into account the area of ​​the bristles 120 to meet the user's needs for photographing the oral cavity. It also effectively ensures that the area and density of the bristles 120 can meet the ideal cleaning requirements, thereby greatly improving the user experience.

[0028] Specifically, in this embodiment, see Figures 1 to 7 The brush head assembly 100 is detachably installed on the power output end 210 of the main unit 200, and the camera assembly 300 is fixed on the power output end 210 of the main unit 200. In this way, the disassembly and replacement of the brush head assembly 100 does not involve the disassembly and replacement of the camera 320, which allows the camera 320 to be used together with the main unit 200. This not only simplifies the disassembly and replacement steps of the brush head assembly 100, but also greatly saves the production and use costs of the camera 320.

[0029] Furthermore, the bristles 120 are embedded at the end of the brush handle 110. Under the action of the adjusting component 400, the separated first section 121 and second section 122 come closer together and fit together, which can be used to hide the camera 320 on the back of the bristles 120. This can effectively ensure that the camera 320 is not directly exposed inside the mouth during the user's brushing process, and ensure that the teeth do not cause hard pressure on the camera 320. This can greatly improve the structural stability of the camera 320 during use and extend its service life.

[0030] It is worth mentioning that, in this embodiment, by setting the camera 320 to correspond to the gap 111 between the first segment 121 and the second segment 122, it can be effectively ensured that the camera 320 is always directly facing the brushing position. When the first segment 121 and the second segment 122 are separated, the camera 320 can collect oral cavity information through the gap 111 between the first segment 121 and the second segment 122, allowing the user to take pictures of the oral cavity without excessive adjustment of hand posture, which conforms to ergonomic design. For example, when the user wants to observe a certain part of the teeth, they only need to align the gap 111 formed by the first segment 121 and the second segment 122 with that position, and can quickly and accurately obtain oral cavity information without excessive adjustment of hand posture.

[0031] In this embodiment, see Figures 7 to 10 The main unit 200 may specifically include a brush handle 220 and an electrically connected main control board, data processing and transmission module, battery, motor, and switch button. See also Figure 7 The brush handle 220 can preferably be configured as a hollow cylindrical shell structure. The main control board, data processing and transmission module and battery are all installed inside the brush handle 220. The switch button is installed on the side wall of the brush handle 220. The motor can specifically include a motor body and a drive shaft 230. The motor body is installed inside the brush handle 220, and the drive shaft 230 extends through the inside of the brush handle 220 to the outside of the power output end 210 to connect with the brush rod 110.

[0032] It is worth mentioning that the motor body is controlled by the main control board, and users can turn the motor body on or off by operating the switch button. Of course, the switch button is not limited to turning on or off; it can also be used to adjust the amplitude and frequency of the motor body's vibration, providing users with more options. It is also worth noting that in this embodiment, various component modules are integrated on the main control board to realize the various functions of the smart toothbrush. The battery powers the motor and the main control board. Under the control of the main control board, the motor can drive the drive shaft 230 to vibrate, thereby causing the brush arm 110 to vibrate synchronously, providing power for the bristles 120 to clean teeth.

[0033] More notably, in this embodiment, see Figure 5 and Figure 6Both the brush handle 110 and the support arm 310 are mounted on the power output end 210, and the two are connected and fitted together, forming a contour that matches the brush handle 220. See details... Figure 7 The brush handle 110 and the support arm 310 have the same outline. One side of the brush handle 110 is planar, forming a mating surface for engaging with the support arm 310, while the other side is arc-shaped. Correspondingly, one side of the support arm 310 is planar, forming a mating surface 311 for engaging with the mating surface, while the other side is arc-shaped, matching the brush handle 110.

[0034] When the brush handle 110 is installed on the power output end 210, that is, inserted into the drive shaft 230, the mating surface and the fitting surface 311 are positioned opposite each other, so that the brush handle 110 and the support arm 310 work together to act on the oral cavity. Furthermore, the peripheral edges of the brush handle 110 and the support arm 310 are smoothly transitioned, which not only makes the overall appearance more aesthetically pleasing, but also ensures that the user will not experience any discomfort in the oral cavity during brushing, thereby greatly improving the comfort of the brushing process.

[0035] It is worth mentioning that in this embodiment, a gap is pre-set between the mating surface and the mating surface 311. This ensures that the camera 320 is not involved in the disassembly and assembly of the brush head assembly 100. Furthermore, during the vibration of the brush head assembly 100, this gap creates space for the brush rod 110 to vibrate, ensuring that the brush rod 110 does not touch the support arm 310 or the camera 320 during vibration, and that the camera 320 does not vibrate synchronously with the brush rod 110. This results in better structural stability and imaging performance of the camera 320, significantly improving the user experience.

[0036] In this embodiment, the camera assembly 300 may further include a lighting source, which can be installed on the support arm 310 and positioned adjacent to the camera 320. By adding a lighting source, this embodiment can assist the camera 320 in taking pictures, thereby improving the clarity of the image. The lighting source is preferably an LED light, but is not limited to it.

[0037] Further, see Figure 10The camera 320 and the lighting source are electrically connected to the main control board. When a user wants to understand their oral health, they can briefly stop brushing and wait for the bristles 120 to return to their original shape after being relieved of pressure on the teeth. The user can then operate the smart toothbrush and control the camera 320 via the main control board to take photos and videos of the oral cavity. If the photos or videos are unclear due to dim lighting, the main control board can also control the lighting source to illuminate the oral cavity, thereby improving the imaging effect. The data processing and transmission module transmits the acquired image information to the terminal device in real time via wired or wireless means. Users can view their oral cavity in real time based on the image displayed on the terminal device to understand its condition and further develop oral health protection plans accordingly. The terminal device can specifically include any display device such as a mobile phone, tablet, laptop, or television, without any limitations.

[0038] It is worth mentioning that the toothpaste used in the smart toothbrush provided in this embodiment is non-foaming, which can largely avoid affecting the normal operation of the camera 320 due to excessive foam filling the oral cavity.

[0039] Furthermore, in this embodiment, both the brush handle 220 and the support arm 310 can be made of rigid materials, such as hard plastic, and the brush handle 220 and the support arm 310 are preferably integrally formed. This allows the camera 320 to be reused together with the main unit 200, which not only simplifies the disassembly and assembly steps of the brush head assembly 100, but also greatly saves the production and usage costs of the camera 320. Moreover, the integrated structure of the brush handle 220 and the support arm 310 can greatly improve the stability of the camera 320 structure during brushing, ensuring that the camera 320 can accurately and clearly collect the user's oral cavity information.

[0040] Furthermore, in this embodiment, the brush handle 110 can be made of an elastic material, such as soft rubber or hard rubber with slight elasticity. No limitations are imposed, and any elastic material is within the scope of this patent. This ensures that the brush handle 110 has tension under the action of the adjusting component 400, facilitating smooth and rapid adjustment of the opening and closing degree of the gap 111 by the adjusting component 400.

[0041] Specifically, see Figure 3 and Figure 4The brush rod 110 can be injection molded to directly form a gap 111. This gap 111 extends from one end of the brush rod 110 into which the bristles 120 are inserted towards the other end of the brush rod 110, but does not penetrate to the end of the brush rod 110 away from the bristles 120. This arrangement allows the brush rod 110 to form a first support rod 112, a second support rod 113, and a connecting body 114. The ends of the first support rod 112 and the second support rod 113 away from the connecting body 114 respectively form the insertion and fixation of the first section 121 and the second section 122, and the connecting body 114 forms the support and fixation of the first support rod 112 and the second support rod 113. Under the action of the adjusting component 400, the first support rod 112 and the second support rod 113 can use their own elastic tension to move closer together or separate, thereby changing the size of the included angle between them, thus achieving the exposure and concealment of the camera 320.

[0042] In this embodiment, the end of the connecting body 114 away from the bristles 120 is provided with a socket for the drive shaft 230 to be inserted. Furthermore, this socket does not extend to the end of the connecting body 114 facing the first support rod 112 and the second support rod 113, thus effectively preventing the drive shaft 230 from interfering with the opening and closing process of the first support rod 112 and the second support rod 113.

[0043] Furthermore, in this embodiment, see Figure 8 and Figure 9 The adjustment assembly 400 may include an operating member 410, a connecting rod 420, and a pin 430. The operating member 410 is mounted on the brush handle 220, and the pin 430 is mounted on the support arm 310 and embedded within the gap 111. The brush handle 220 has a slide rail 221 that connects to the support arm 310. The connecting rod 420 is slidably disposed within the slide rail 221, with one end abutting the operating member 410 and the other end abutting the pin 430. The operating member 410 operably drives the connecting rod 420 to slide back and forth along the slide rail 221, thereby causing the pin 430 to slide back and forth along the gap 111, thus adjusting the opening degree of the gap 111.

[0044] Preferably, see continue to see Figure 8 and Figure 9 The operating component 410 specifically includes an operating part and a connecting part mounted on the operating part. A track 222 is provided on the side wall of the brush handle 220, and the operating part is slidably connected to the track 222. The connecting part extends through the track 222 into the interior of the brush handle 220 to engage with the connecting rod 420. Notably, the end of the operating part opposite to the connecting part protrudes from the outside of the brush handle 220, allowing the user's fingers to press against it and operate it to push the operating part to slide back and forth along the track 222. This, in turn, causes the connecting rod 420 to slide back and forth along the slide rail 221, which in turn causes the pin 430 to slide back and forth along the gap 111, thereby adjusting the opening and closing degree of the gap 111.

[0045] Of course, in this embodiment, the adjustment component 400 is not limited to the above structure. It only needs to ensure that it can achieve the effect of adjusting the opening degree of the gap 111. For example, it can adopt an electric drive structure, which is within the protection scope of this patent. It will not be described in detail here. It can be flexibly set according to the actual adaptation scenario.

[0046] Furthermore, in this embodiment, see Figures 5 to 7 When the brush rod 110 is inserted into the drive shaft 230, the mating surface 311 is provided with a groove 3111 that is connected to the slide rail 221 at the position of the gap 111 of the brush rod 110. The width of the groove 3111 is matched with the diameter of the pin 430. It should at least ensure that when the pin 430 is located in the groove 3111, the pin 430 can slide back and forth relative to the groove 3111 under the drive of the connecting rod 420, so as to adjust the angle range between the first support rod 112 and the second support rod 113.

[0047] Specifically, see Figure 3 and Figure 4 A receiving hole 1111 can be made at a certain position along the length of the gap 111. The diameter of the receiving hole 1111 should be at least larger than the diameter of the pin 430. In this way, during the reciprocating sliding of the pin 430 relative to the slide groove 3111, when the pin 430 slides into the receiving hole 1111, the pin 430 releases the restriction on the position of the gap 111 between the first support rod 112 and the second support rod 113. At this time, the first support rod 112 and the second support rod 113 are under their own elastic tension. The first and second sections 121 and 122, which are separated, move closer together and retract synchronously with the first and second support rods 112 and 113, respectively. This allows the camera 320 to be hidden behind the bristles 120. This effectively ensures that the camera 320 is not directly exposed inside the mouth during brushing, preventing teeth from exerting hard pressure on the camera 320. This greatly improves the structural stability of the camera 320 during use and extends its service life.

[0048] Furthermore, in this embodiment, a protective hole 1112 may be provided at the end of the brush rod 110 corresponding to the gap 111 facing the connecting body 114, that is, at the end away from the bristles 120. The protective hole 1112 may be a circular hole. In this way, when the gap 111 is squeezed by the pin 430, the end of the gap 111 will not be easily torn by the action of the pin 430, or even the connecting body 114 will be broken into two parts. The setting of the protective hole 1112 can greatly improve the structural stability of the brush rod 110 during the opening and closing process.

[0049] Preferably, the receiving hole 1111 can be opened on the side of the gap 111 adjacent to the protective hole 1112, and at least a certain distance should be ensured between the receiving hole 1111 and the protective hole 1112. In this way, by operating the operating member 410 again, the connecting rod 420 drives the pin 430 to slide towards the receiving hole 1111 away from the bristles 120, that is, the receiving hole 1111 slides towards the side of the protective hole 1112. Since the pin 430 slides in the direction away from the bristles 120, under the cooperation of the connecting body 114, the included angle between the first support rod 112 and the second support rod 113 can gradually increase. Finally, when the camera 320 is exposed between the first section 121 and the second section 122, the user can stop the adjustment operation and directly point the camera 320 at a specific location in the oral cavity to take a picture or video. The operation is simple, the structure is stable, and the practicality is high. Preferably, the junction of the receiving hole 1111 and the gap 111 can be rounded, which facilitates the pin 430 to slide quickly and smoothly into the receiving hole 1111 through the gap 111 and out of the receiving hole 1111 to the position of the gap 111.

[0050] This embodiment can meet the user's needs for oral cavity imaging while taking into account the area of ​​the bristles 120, and effectively ensure that the area and density of the bristles 120 can meet the ideal cleaning needs, thereby greatly improving the user experience.

[0051] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
