[0066] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0067] To address the problems in the background art, this application provides an electric toothbrush with multiple functions to meet users' needs for a multi-functional electric toothbrush.

[0068] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The electric toothbrush includes a housing 2, multiple brush head assemblies 1, a drive assembly 3, and a motor assembly 4.

[0069] The outer casing 2 may include a handle 21, a button 22, a bottom cover 24, a sealing ring 23, and a bottom cover 24. The handle 21 may be designed as a long and slender structure for easy gripping. The handle 21 has a hollow structure with openings at both ends. One opening allows a portion of the drive assembly 3 to extend and connect to the brush head assembly 1, while the other opening facilitates the installation of the drive assembly 3 and the mechanism assembly 4 into the hollow structure of the handle 21. Multiple brush head assemblies 1 can be detachably and replaceably installed at one end of the handle 21 as needed. The button 22 may be located on the handle 21 and may include, but is not limited to, different cleaning modes, cleaning intensity settings, and function switching. The opening at the other end of the handle 21 can be sealed by the bottom cover 24. A sealing ring 23 may be provided between the bottom cover 24 and the handle 21 to prevent humid gases or water from entering the hollow structure of the handle 21 from the connection point between the bottom cover 24 and the handle 21, thus affecting the use of the drive assembly 3 and the mechanism assembly 4.

[0070] Multiple brush head assemblies 1 include a brush handle 11 and a brush head holder 16. A brush head sealing ring 17 can be provided between the brush head holder 16 and the brush handle 11 to prevent the electrical components between the brush head assembly 1 and the drive assembly 3 from being affected by moisture. Here, the brush handle 11 is not limited to cleaning the oral cavity; the specific structural form of the brush handle 11 can vary depending on the different brush head assemblies 1. The brush handle 11 has functional components for cleaning and / or heating teeth, and / or performing light care, or performing oral examinations, or performing oral tests. That is, the brush handle 11 is provided with functional components, for example, one of which can perform any combination of one or more of the following functions:

[0071] Clean your teeth;

[0072] Heating the oral cavity;

[0073] Light therapy.

[0074] Another functional component can perform oral cavity examinations. Yet another functional component can perform oral cavity detection, such as breath detection. Corresponding brush handles 11 can be used for different functional components.

[0075] The functional component has a functional connection line 15 for electrical connection with the drive assembly 3. The functional component is provided with a distinguishing unit for different functional components; for example, each functional component has a distinguishing resistor 153 or a distinguishing chip for distinguishing different functional components. Different types of brush head assemblies 1 correspond to different distinguishing resistors 153 or distinguishing chips for their functional components. The mechanism assembly 4 distinguishes the brush head assemblies 1 corresponding to different types of functional components by identifying the resistance value of the distinguishing resistor 153, and provides the corresponding function for that brush head assembly 1.

[0076] Each functional component of the brush head assembly 1 can be distinguished by a unique identification chip. In addition to identifying the type of brush head assembly 1 through the identification code, it can also record the usage time of each brush handle 11, reminding users whether the service life has been reached and indicating whether a new brush head assembly 1 needs to be replaced.

[0077] For example, the mechanism assembly 4 can connect to the distinguishing chip through the drive assembly 3 and read the identification code of the distinguishing chip to know the type of brush head assembly 1 corresponding to the distinguishing chip.

[0078] Multiple brush head assemblies 1 can be interchangeably mounted on one end of the housing 2 via brush head brackets 16. For example, the brush head assembly 1 can be detachably mounted on one end of the handle 21. The brush head assembly 1 and one end of the handle 21 can be detachably connected by a snap-fit ​​or by a threaded connection. A top sealing ring 31 is provided on the top of the handle 21 to seal the connection between the handle 21 and the brush head assembly 1, preventing moisture from entering the handle 21.

[0079] The drive assembly 3 is housed in the outer casing 2. The drive assembly 3 includes a motor 37 and a main unit connection cable 35. The motor 37 can be mounted inside the outer casing 2 via a motor bracket 36. Vibration can also be prevented by installing anti-vibration pads 38 on the motor bracket 36. The motor can be, but is not limited to, a sonic motor. The motor is electrically connected to the functional components via the main unit connection cable 35. For example, the drive assembly 3 can be housed within the hollow structure of the handle 21. Alternatively, a portion of the drive assembly 3 can extend from the hollow structure to the outside of the handle 21; for example, the motor's drive shaft 371 can extend out of the handle 21 and connect to the brush head assembly 1. A sealing sleeve 34 for the drive shaft 371 is also provided on the motor. The sealing sleeve 34 cooperates with the connecting bracket 33 to prevent moisture from entering the interior of the handle 21 from the periphery of the drive shaft 371 and the main unit connection cable 35.

[0080] The core assembly 4 is housed within the outer casing 2 and connected to the drive assembly 3. It supplies power to the drive assembly 3 and sends control signals to it, enabling the drive assembly 3 to activate its functional components upon receiving the corresponding control signals. The core assembly 4 can be understood as the core control component of the electric toothbrush. It can control the switching of various functions of the electric toothbrush based on the actions of the buttons 22 on the handle 21, and can also adjust the brushing mode and intensity based on the actions of the buttons 22. Furthermore, the core assembly 4 can also receive signals or data from other structures in the brush head assembly 1 and issue control signals accordingly.

[0081] This application sets up multiple brush head components 1, each with different functions. The brush head components 1 can be replaced according to the user's needs, so that multiple brush head components 1 can be adapted to the outer shell 2. In addition, the same brush head component 1 can also have multiple functions, thus meeting the user's needs for a multi-functional electric toothbrush.

[0082] In some embodiments, such as Figure 2 and Figure 6As shown, the multiple brush head assemblies 1 include a first brush head assembly 1. One end of the brush handle 11 of the first brush head assembly 1 is provided with a brush head, which is equipped with bristles for cleaning teeth or other areas inside the oral cavity. The brush head has a first hollow cavity, and one side of the first hollow cavity has a first opening. A rear cover is provided at the first opening to seal it. A sealing ring can also be provided between the rear cover and the first opening to prevent moisture from entering the first hollow cavity from the connection point between the rear cover and the first opening, thus affecting the operation of the electrical components inside the first hollow cavity.

[0083] The first brush head assembly 1 includes a first connecting line (one type of functional connecting line 15) and a heating film 13. One end of the first connecting line is connected to one end of the main unit connecting line 35, and the other end is connected to the heating film 13. The core assembly 4 sends a control signal to the heating film 13 via the main unit connecting line 35 and the first connecting line. This control signal controls the heating film 13 to heat up, thereby promoting oral blood circulation and achieving oral care functions. The heating film 13 can be disposed within the first hollow cavity, and its shape can be configured to correspond to the longitudinal cross-sectional shape of the first hollow cavity, meaning the heating film 13 can largely cover the brush head to heat the oral cavity with the largest possible heating area. It is understood that the heating temperature here is adapted to the temperature of the human oral cavity and will not cause discomfort to the user.

[0084] For example, the mechanism assembly 4 can be connected to the host connection cable 35 via the circuit board 41, and the circuit board 41 can send control signals to the heating film 13 via the host connection cable 35 and the first connection cable.

[0085] And / or,

[0086] The first brush head assembly 1 also includes a light group 151. A first light-transmitting plate 111 can be disposed in the gaps between the bristles. The outer surface of the first light-transmitting plate 111 is exposed, and the inner surface can serve as the inner wall of the first hollow cavity. The first light-transmitting plate 111 can be, but is not limited to, an acrylic light-transmitting plate. The other end of the first connecting line is also connected to the light group 151. The mechanism assembly 4 controls the light group 151 to emit red light and / or blue light through the host connecting line 35 and the first connecting line. The red light and / or blue light can pass through the first light-transmitting plate 111 to care for the teeth and gums. For example, red light can care for the gums, and blue light can whiten the teeth.

[0087] The lamp assembly 151 can be disposed within the first hollow cavity, so that the red and / or blue light emitted by the lamp assembly 151 can pass through the first light-transmitting plate 111 and reach the teeth and gums. The lamp assembly 151 may be, but is not limited to, an LED lamp assembly 151.

[0088] The differentiating resistor 153 or differentiating chip can be set on the first connection line, and data transmission with the mechanism assembly 4 can be realized through the first connection line and the host connection line 35.

[0089] The first brush head assembly 1 has a brush handle 11 with bristles, which can be used to brush teeth; it can also heat the oral cavity through the heating film 13 to promote blood circulation and oral care; and it can also achieve the effect of caring for teeth and gums through the red light and / or blue light emitted by the lamp group 151.

[0090] In some embodiments, such as Figure 2 As shown, the first brush head assembly 1 also includes a thermistor 14, which is connected to the first connecting line and can be positioned inside the first hollow cavity to detect the temperature inside the cavity. The thermistor 14 then sends the detection signal to the core assembly 4 via the host connecting line 35 and the first connecting line. Upon receiving the detection signal, the core assembly 4 issues a corresponding control signal to control the power supply to the heating film 13, preventing the heating film 13 from continuously heating and causing excessively high oral temperature, thus affecting the user's experience.

[0091] For example, continuing with the above embodiments, the movement assembly 4 can receive detection signals and send control signals through the circuit board 41.

[0092] The core assembly 4 can control the power supply of the heating film 13 based on the resistance of the thermistor 14, so as to avoid overheating and affect oral and dental health, and improve the user experience.

[0093] In some embodiments, such as Figure 7 and Figure 6 As shown, the multiple brush head assemblies 1 include a second brush head assembly 1. One end of the brush handle 11 of the second brush head assembly has a second hollow cavity, and one side of the second hollow cavity has a second opening. A second light-transmitting plate 112 for sealing the second opening is provided at the second opening. A sealing ring can be provided between the second light-transmitting plate 112 and the second opening to prevent moisture from entering the second hollow cavity. The second light-transmitting plate 112 can be, but is not limited to, an acrylic light-transmitting plate.

[0094] The second brush head assembly 1 includes a second connecting cable (one type of functional connecting cable 15) and a camera 18. The camera 18 can be disposed within the second hollow cavity. The second light-transmitting plate 112 is used to transmit light and protect the camera 18, preventing moisture from entering the second hollow cavity. One end of the second connecting cable is connected to one end of the host connecting cable 35, and the other end of the second connecting cable is connected to the camera 18. The mechanism assembly 4 controls the opening and closing of the camera 18 via the second connecting cable, and the images captured by the camera 18 are sent to the mechanism assembly 4 via the second connecting cable. More specifically, the mechanism assembly 4 controls the opening and closing of the camera 18 via the host connecting cable 35 and the second connecting cable, and the images captured by the camera 18 are sent to the mechanism assembly 4 via the second connecting cable and the host connecting cable 35.

[0095] The movement component 4 can also transmit wireless signals to an electronic device to display the image captured by the camera 18 on the electronic device. The electronic device can be a user's smartwatch, tablet, or other wearable device.

[0096] The differentiating resistor 153 or differentiating chip can be set on the second connection line, and data transmission with the mechanism assembly 4 can be realized through the second connection line and the host connection line 35.

[0097] The second brush head assembly 1 can capture images of the oral cavity through the camera 18 and send the captured results to the user's electronic device through the core assembly 4. This allows the user to clearly understand the oral cavity condition through the images sent by the core assembly 4, such as whether brushing is thorough and the brightness of teeth after whitening.

[0098] In some embodiments, such as Figure 7 As shown, the brush handle 11 of the second brush head assembly 1 is also provided with a light-transmitting hole 113, and a third light-transmitting plate is provided at the light-transmitting hole 113. The third light-transmitting plate can also be sealed at the light-transmitting hole 113. The second brush head assembly 1 also includes a light-emitting lamp 19. The light-emitting lamp 19 is connected to the second connecting line. The mechanism assembly 4 controls the opening and closing of the light-emitting lamp 19 through the host connecting line 35 and the second connecting line. When the light-emitting lamp 19 is on, the light emitted by the light-emitting lamp 19 reaches the oral cavity through the third light-transmitting plate and illuminates the oral cavity, providing a lighting environment for the camera 18 to take pictures.

[0099] The light source 19 can provide a good lighting environment for the camera 18 to capture images, ensuring that the oral cavity images captured by the camera 18 are clearer and can more accurately reflect the condition of the oral cavity.

[0100] In some embodiments, such as Figure 8 and Figure 6As shown, the multiple brush head assemblies 1 include a third brush head assembly 1, which includes a third connecting line (one type of functional connecting line 15) and a breath detection module 20. A distinguishing resistor 153 or a distinguishing chip can be disposed on the third connecting line, and data transmission with the mechanism assembly 4 is achieved through the third connecting line and the host connecting line 35. The breath detection module 20 can, but is not limited to, perform chromatographic analysis using a gas chromatograph to detect the components of exhaled gas. This method requires slowly exhaling gas into the collector of the breath detection module 20 during sampling, followed by condensation and analysis. Furthermore, a sulfide assay detector detects halitosis by detecting volatile sulfides produced in the mouth.

[0101] The brush rod 11 has a third hollow cavity, and one end of the brush rod 11 is provided with an air hole 114 that communicates with the third hollow cavity. The user can blow air into the air hole 114 of the brush rod 11, and the air enters the third hollow cavity through the air hole 114 and is detected by the breath detection module 20.

[0102] One end of the third connecting cable is connected to one end of the main unit connecting cable 35, and the other end of the third connecting cable is connected to the breath detection module 20. When oral air enters the third hollow cavity through the air hole 114, the breath detection module 20 can send oral detection data to the core assembly 4 via the third connecting cable. The breath detection module 20 is located inside the third hollow cavity. The core assembly 4 can send the detection results from the breath detection module 20 to the user's electronic device, allowing the user to clearly understand the oral condition through the detection results sent by the core assembly 4. This electric toothbrush can detect oral breath through the breath detection module 20 via the third brush head assembly 1.

[0103] In some embodiments, the third brush head assembly 1 further includes multiple indicator lights connected to the motor assembly 4. For example, the indicator lights can be located on the handle 21 or the brush bar 11, or, as needed, in other positions on the electric toothbrush. After receiving oral cavity detection data from the breath detection module, the motor assembly 4 sends corresponding control signals to the indicator lights to control different indicator lights to illuminate. The user can accurately judge the breath detection status by observing the indicator lights. Different indicator lights represent the read breath values. In other words, the indicator lights clearly reflect the breath condition in the oral cavity, allowing the user to clearly understand the current breath condition.

[0104] In some embodiments, such as Figure 4 and Figure 6As shown, the drive assembly 3 also includes a connecting bracket 33, which is mounted on the motor.

The battery 46 also has a positive terminal 42 and a negative terminal 44 respectively. The battery 46 is also connected to the circuit board 41 and the motor 37 to supply power to the circuit board 41 and the motor, ensuring the normal power supply of the circuit board 41 and the motor 37. The battery in the electric toothbrush can be charged through the charging coil 45, and the battery supplies power to the circuit board 41 and the motor.

[0108] In some embodiments, such as Figure 9 As shown, one end of the host connection cable 35 is also provided with a contact pin 352, and the host connection cable 35 connects to the spring pin 154 of the functional component through the contact pin 352. Figure 10 Electrical connection. For example, specifically, a spring pin 154 is provided at one end of the first, second, or third connecting line of the functional component that connects to the host connecting line 35. The spring pin 154 is electrically connected to the contact pin 352 to improve current conduction efficiency in high operating current scenarios.

[0109] like Figure 11 As shown, one end of the host connection cable 35 may be equipped with a connector 351 in addition to a contact pin 352. The end of the first, second, or third connection cable of the functional component that connects to the host connection cable 35 is equipped with a connector 152 (e.g., ...). Figure 12As shown, connector 152 can be inserted into connector 351 to securely connect the main unit connection cable 35 to the first, second, or third connection cable of the functional component, preventing damage to the connection between contact pin 352 and spring pin 154. While the brush head assembly 1 vibrates to clean the teeth, connector 351 and connector 152 also vibrate synchronously, maintaining a good connection.

[0110] The foregoing has described in detail several embodiments of the present utility model, but the present utility model is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of the present utility model, and these variations and modifications should all fall within the scope of protection claimed by the present utility model.
