Description

Technical Field

[0001] This utility model relates to the field of electric toothbrushes, and more particularly to a smart toothbrush with dental examination and diagnostic functions. Background Technology

[0002] Toothbrushes are everyday personal care tools. With technological advancements, toothbrush design has incorporated numerous technological elements, moving towards electrification and intelligentization. For example, by utilizing high-frequency vibration and sonic technology, smart toothbrushes can efficiently clean teeth. Simultaneously, equipped sensors can analyze the user's brushing data in real time, converting it into visualized information to optimize the user experience. This technology not only improves cleaning effectiveness but also provides users with personalized oral care solutions. To enhance user experience, many smart toothbrush products simplify daily oral care procedures through innovative technologies such as Bluetooth connectivity and mobile applications. Users can download a dedicated app to understand and manage brushing results, receiving feedback and suggestions. This highly interactive experience ensures users can complete oral cleaning more efficiently while enjoying personalized care plans, making the brushing process more intelligent and convenient. However, current smart toothbrush products on the market still rely solely on simple sensors, such as pressure sensors, and recording brushing time and frequency to assess and provide feedback on brushing effectiveness. They lack direct observation and detection methods for the user's oral hygiene, brushing cleaning effect, and dental health. If optical sensors are introduced into toothbrushes, users can directly observe the condition of their teeth during daily brushing. Combined with a mobile app and AI image analysis in the background, a more scientific and accurate assessment of the user's dental condition and brushing effectiveness can be made, allowing for the timely detection of potential dental problems and providing users with a better oral care experience.

[0003] This invention addresses current market demands by proposing a smart toothbrush. By incorporating an optical sensing device combining optical fibers and optical sensors into the brush head, users can check the health of their teeth and the cleaning effect before and after brushing while brushing, providing a more intelligent oral care experience.

[0017] This utility model proposes a smart toothbrush, the overall structure of which is as follows: Figure 1 As shown in the figure, the smart toothbrush includes a charging base A1 and a toothbrush body. The charging base A1 contains a key management circuit and a transmitting coil; the bottom of the toothbrush body is equipped with a receiving coil, which allows for wireless charging via electromagnetic induction when the toothbrush body is placed in the charging base. The toothbrush body includes a handle A2 and a head assembly A3. The handle A2 has a touch button B1 on its front for controlling the toothbrush's start, stop, and internal motor speed adjustment; the back has a rubber layer B2 with anti-slip stripes; and the front also has several status indicator lights B3.

[0018] The handle internally houses a control board, motor, battery, and the aforementioned wireless charging receiver coil. The control board integrates a main control processor, touch buttons, motor drive circuitry, battery charge / discharge management circuitry, wireless interface, camera module, camera illumination LED, and status indicator LED. The motor is fixed inside the handle near the head assembly via a mounting bracket and connected to the motor drive circuitry on the control board via a cable. The battery is housed in a battery compartment inside the handle near the anti-slip rubber layer and connected to the power positive and negative pads on the control board via a cable. The wireless interface includes a wireless transceiver chip and a PCB antenna. The control board is mounted inside the handle, close to the touch buttons and status indicator lights, with the touch buttons and status indicator lights aligned with their corresponding positions on the handle. The wireless interface is either a WiFi or Bluetooth interface.

[0019] The head assembly A3 includes a connecting rod and a brush head. The connecting rod contains a transmission structure for transmitting the rotation output from the motor to the brush head. The brush head includes a head base A4 and a rotating brush head A5. Several flexible guiding optical fibers B3 are fixed to the edge of the head base A4, with the fiber protruding from the head base at a height lower than the brush bristles. These fibers are connected to the camera module and the camera illumination LED light-emitting surface on the control board through the internal space of the head base A4 and the connecting rod. A circular rotating base is located in the middle of the head base A4, on which the rotating brush head A5 is mounted. Figure 2 A structural diagram of the brush head section is provided.

[0020] Figure 3A top view of the brush head section is further provided.
