[0039] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0040] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0041] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0042] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0043] The present disclosure provides an oral care device, which can effectively remove bacteria and food residues on the tooth surface and in the gaps between teeth. Specifically, the oral care device can be a tooth flushing device, a flushing integrated device, etc. The oral care device includes: a fluid connection component and a handle, and the fluid connection component is removably connected to the handle. The fluid connection component is used to send a water source into the handle to achieve water communication. The handle is configured to be suitable for holding, and the user can hold the handle to flush or brush the teeth.

[0044] The fluid connection assembly includes a connection assembly inlet connected to the fluid source and a connection assembly outlet connected to the handle. For example, fluid such as water, mouthwash or oral care liquid can flow into the fluid connection assembly from the connection assembly inlet, and when the handle is installed in place, flow out of the fluid connection assembly from the connection assembly outlet, thereby flowing into the handle.

[0045] Specifically, the handle is provided with an inner cavity and an adapter cavity separated from each other. The inner cavity is configured to accommodate components that require water isolation, such as a motherboard, a motor, and a battery; the fluid connection assembly is configured to be detachably connected in the adapter cavity. In the installed state, the water flow path between the handle and the fluid connection assembly is connected, and the fluid can flow to the handle. The fluid can flow from the outlet of the adapter assembly into the adapter cavity, and further flow into the water channel inside the handle, thereby realizing the function of flushing teeth.

[0046] In order to accurately identify whether the handle is connected to the water source and whether the waterway is unobstructed, a trigger unit is provided in the fluid connection assembly of the present disclosure, and a sensor unit is provided in the inner cavity. When the fluid connection assembly is located at a predetermined position, the sensor unit is configured to be triggered under the action of the trigger unit. The predetermined position may be a state in which the fluid connection assembly is installed in place, that is, a state in which the water flow path between the handle and the fluid connection assembly is connected. In this way, the sensor unit can be triggered when the handle is connected to the water source and the waterway is unobstructed, thereby achieving accurate identification and improving the user experience.

[0047] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0048] refer to Figures 1 to 3 The present disclosure provides an oral care device, comprising: a fluid connection component 2 and a handle 3, wherein the fluid connection component 2 is removably connected to the handle 3. Figure 2 As shown, the fluid connection assembly 2 can be connected to the water pipe 11, so as to deliver the external water source into the handle 3. The handle 3 is configured to be suitable for holding, and the user can hold the handle 3 to rinse or brush the teeth.

[0049] In a specific embodiment, the oral care device can be a flushing device, such as Figure 2As shown, the handle 3 includes a hand-held portion and a care head 30, and the care head 30 specifically includes a brush head and / or a nozzle. The brush head may include a plurality of bristle clusters, and the bristle clusters are used to contact the teeth to achieve the function of brushing teeth; the nozzle can be connected to the fluid passage in the handle 3 to achieve the function of flushing teeth. The oral care device provided in this embodiment can realize the function of both a toothbrush and a water flosser, thereby improving the cleaning effect of the oral cavity. When the fluid connection component 2 and the handle 3 are separated from each other, the water path between the two is disconnected, and the handle 3 can no longer flush teeth. At this time, the handle 3 can be used as a toothbrush.

[0050] refer to Figure 3 and Figure 7 , the fluid connection assembly 2 includes a connection assembly inlet 24 connected to the fluid source, and a connection assembly outlet 26 connected to the handle 3. The connection assembly inlet 24 can be connected to the water pipe 11, and the fluid can flow from the connection assembly inlet 24 into the fluid connection assembly 2. When the handle is installed in place, the fluid can flow out of the fluid connection assembly 2 from the connection assembly outlet 26 and flow into the handle 3.

[0051] In one embodiment of the present disclosure, the oral care device may be a desktop device. Figure 1 As shown, the oral care device also includes a body 1, in which a fluid storage chamber is provided, and a connection component inlet 24 is configured to communicate with the fluid storage chamber. The fluid storage chamber is used to store fluids such as clean water, mouthwash or oral care liquid, and a water pump may also be provided in the body 1 to pump the fluid in the fluid storage chamber into the handle 3. Specifically, the connection component inlet 24 may be connected to the fluid storage chamber inside the body 1 through a water pipe 11, and when the fluid connection component 2 is connected to the handle 3, the liquid in the fluid storage chamber can be pumped into the handle 3, so as to flush the teeth.

[0052] In another embodiment of the present disclosure, the oral care device may not include the body 1, and the fluid connection component 2 may be directly connected to an external water source, for example, may be directly connected to a faucet.

[0053] refer to Figure 3 and Figure 8 The handle 3 is provided with an inner cavity 320 and a transfer cavity 330 separated from each other, referring to Figure 2 and Figure 4 The handle 3 includes a housing 36 and a mounting bracket 32 ​​disposed inside the housing 36. The mounting bracket 32 ​​can be used to mount components inside the handle 3, such as a battery, a motor, and a mainboard 31. One side of the mounting bracket 32 ​​and the housing 36 form an inner cavity 320. Specifically, the side of the mounting bracket 32 ​​close to the care head 30 and the housing 36 form a closed inner cavity 320.

[0054] In one embodiment of the present disclosure, reference Figure 4 and Figure 8 A waterproof member 322 is provided between the mounting bracket 32 ​​and the inner wall of the housing 36. The waterproof member 322 is constructed as a closed ring around the axis of the handle 3. The waterproof member 322 can ensure that the fluid in the adapter cavity 330 does not penetrate into the inner cavity 320, thereby achieving waterproofing of the inner cavity 320. The inner cavity 320 can be kept dry, thereby protecting the components that need to be waterproof, such as the battery, motor, and mainboard 31 in the inner cavity 320, from contacting the liquid, thereby extending the life of the oral care device.

[0055] The adapter cavity 330 is located on the other side of the mounting bracket 32, that is, the side away from the care head 30, and the fluid connection assembly 2 is configured to be detachably connected in the adapter cavity 330. In one embodiment of the present disclosure, Figure 4 The handle 3 includes a fixing member 33 and a locking member 4 movably connected to the fixing member 33, wherein the transfer cavity 330 is arranged in the fixing member 33. Figure 5 The fluid connection assembly 2 includes a clamp head 21, and a clamping groove 211 is provided on the clamp head 21. The locking member 4 can move between a locking position and an opening position relative to the fixing member 33: when in the locking position, the locking member 4 is engaged with the clamping groove 211, thereby locking the fluid connection assembly 2 in the adapter cavity 330; when in the opening position, the locking member 4 is configured to be separated from the clamping groove 211, so that the fluid connection assembly 2 can be detached from the handle 3.

[0056] The locking member 4 can be kept in the locked position in the natural state, so that the fluid connection assembly 2 can be stably installed in the adapter cavity 330. Figure 2 , Figure 4 and Fig. 9 The handle 3 also includes a button 35 and a spring 34. Figure 2 As shown, the button 35 is exposed outside the housing 36. When the user pushes the button 35, the lock member 4 can move from the locked position to the open position, so that the fluid connection assembly 2 can be easily detached from the handle 3; when the external force is removed, the button 35 can be reset under the elastic force of the spring 34. In this embodiment, by providing the button 35, it is possible to easily control the lock member 4 to move between the open position and the locked position, thereby realizing the rapid disassembly and assembly between the fluid connection assembly 2 and the handle 3.

[0057] In the installed state, the water flow path between the handle 3 and the fluid connection assembly 2 is connected, and the fluid can flow to the handle 3. Water can flow from the connection assembly outlet 26 into the adapter cavity 330, and further flow into the water channel inside the handle 3, thereby achieving the tooth flushing function.

[0058] In one embodiment of the present disclosure, reference Figure 5, Figures 7 to 9 The fluid connection assembly 2 is provided with a valve assembly, the valve assembly includes a sealing plug 22 and an elastic member 23, and the elastic member 23 can be a spring. Figure 7 As shown, the sealing plug 22 is constructed to seal the water flow path when the elastic member 23 is in a natural state. Specifically, the valve assembly can be arranged inside the main body 20 of the fluid connection assembly 2. The sealing plug 22 has a tendency to move upward under the elastic force of the elastic member 23, thereby sealing the connection assembly outlet 26.

[0059] like Figure 8 As shown, the mounting bracket 32 ​​includes a water intake portion 321 extending into the transfer cavity 330. In the installed state, as shown in FIG. Fig. 9 As shown, the water intake portion 321 is configured to push the sealing plug 22 to open the water flow path between the handle 3 and the fluid connection assembly 2. In the detached state, the water intake portion 321 is separated from the sealing plug 22, and the sealing plug 22 is configured to be reset under the elastic force of the elastic member 23. The sealing plug 22 will compress the elastic member 23 while being pushed by the water intake portion 321, so that when the thrust of the water intake portion 321 disappears, it can be reset under the elastic force to seal the connection assembly outlet 26 again.

[0060] In a specific embodiment of the present disclosure, Figure 8 As shown, the water intake portion 321 is provided with a water intake channel 3212, and the water intake portion 321 is provided with a water intake hole 3211, which can be specifically provided on the side wall or the bottom wall of the water intake portion 321. Fig. 9 As shown, when the water intake portion 321 pushes the sealing plug 22, the fluid can flow into the water intake channel 3212 through the water intake hole 3211. The upper end of the water intake channel 3212 can be connected to the water channel inside the handle 3, so as to flow to the nozzle of the care head 30 for spraying.

[0061] In a specific embodiment of the present disclosure, Figure 7 As shown, an elastic waterproof ring 25 is provided in the fluid connection assembly 2 near the sealing plug 22. When the water intake portion 321 extends from the connection assembly outlet 26 and pushes the sealing plug 22, the elastic waterproof ring 25 can cooperate with the side wall of the water intake portion 321 to form a sealing structure to ensure that the fluid can only flow into the water intake channel 3212 and will not overflow from the outside of the water intake portion 321, thereby preventing water leakage of the device and improving the user experience.

[0062] The present disclosure realizes a one-way sealed connection assembly outlet 26 by arranging a valve assembly in the fluid connection assembly 2. The connection assembly inlet 24 of the fluid connection assembly 2 can be connected to the fluid storage chamber in the body 1 through the water pipe 11, and sealed by the valve assembly. The water intake portion 321 extending into the adapter cavity 330 can open the valve assembly and connect the water flow path between the handle 3 and the fluid connection assembly 2.

[0063] In order to accurately identify whether the handle is connected to the water source and whether the waterway is unobstructed, a trigger unit is provided in the fluid connection component 2 of the present disclosure, and a sensor unit is provided in the inner cavity 320. When the fluid connection component 2 is located at a predetermined position, the sensor unit is configured to be triggered under the action of the trigger unit. The sensor unit can be a proximity switch, specifically, an inductive, capacitive, Hall, AC, DC and other types of proximity switches. The present disclosure does not limit the specific form of the sensor unit. When the distance between the trigger unit and the sensor unit is less than a threshold value, it means that the fluid connection component 2 has reached the predetermined position, and the sensor unit can be triggered under the action of the trigger unit.

[0064] The predetermined position may be a state where the fluid connection assembly 2 is installed in place, that is, a state where the water flow path between the handle 3 and the fluid connection assembly 2 is connected. In this way, the sensor unit can be triggered when the handle 3 is connected to the water source and the water path is unobstructed, thereby achieving accurate identification and improving the user experience.

[0065] In one embodiment of the present disclosure, a sonic motor is provided in the inner cavity 320, and the sonic motor is configured to drive the care head 30 to vibrate. Specifically, the sonic motor is used to drive the brush head to vibrate or swing, thereby achieving the function of brushing teeth. A control unit is provided in the inner cavity 320, and a control unit is provided in the inner cavity 320. Figure 4 The control unit may be a mainboard 31, and the control unit is configured to control the sonic motor to remain in an off or on state in response to a trigger signal from the sensor unit. When the sensor unit sends a trigger signal, it means that the water path between the handle 3 and the fluid connection assembly 2 is unobstructed, and the user uses the handle 3 as a water flosser instead of an electric toothbrush.

[0066] If the sonic motor for brushing teeth and the water pump for flushing teeth work at the same time, the user experience will be poor. Specifically, if the care head 30 vibrates at the same time during the process of flushing teeth, the water flow for flushing teeth will be unstable, which is not conducive to the user's operation of the handle 3. This embodiment is based on the trigger signal of the sensor unit to control the sonic motor to remain in the off state in the flushing mode, that is, to turn off the sonic motor when the water path is connected, so that during the process of flushing teeth, the user will not start the sonic motor due to accidental touch, thereby improving the user's experience when flushing teeth. In one embodiment of the present disclosure, the drive shaft of the sonic motor can be hollow, so as to facilitate the transportation of fluid from the water intake channel 3212 to the nozzle for spraying. The nozzle can be optionally integrated on the brush head, or it can be an independent component.

[0067] When the fluid connection assembly 2 is detached from the adapter cavity 330, the care head 30 is configured to vibrate under the driving action of the sonic motor. When the sensor unit recognizes that the fluid connection assembly 2 is no longer in the predetermined position based on the trigger unit, it means that the water path between the handle 3 and the fluid connection assembly 2 is disconnected, and the sonic motor can be turned on, so that the user can use the handle 3 as an electric toothbrush.

[0068] The present invention integrates the functions of flushing and brushing teeth on a desktop device, and determines the connection status of the water circuit by accurately identifying whether the fluid connection component 2 is located at a predetermined position, so as to distinguish and isolate the two functions of brushing and flushing: when the water circuit is connected, it means that the user is going to use the flushing function, so the sonic motor is controlled to remain in the off state; when the water circuit is disconnected, the user can use the brushing function, so the sonic motor can be controlled to turn on.

[0069] In one embodiment of the present disclosure, reference Figure 6 , the sensor unit is arranged at a position adjacent to the transfer cavity 330, and the sensing area of ​​the sensor unit at least partially overlaps with the positive projection of the trigger unit in the axial direction of the handle 3. Specifically, the trigger unit is the magnet 27, the sensor unit is the Hall switch 311, and the Hall switch 311 can be arranged at one end of the main board 31 adjacent to the transfer cavity 330, so as to facilitate the Hall switch 311 to sense the magnet 27. The sensing area of ​​the Hall switch 311 at least partially overlaps with the positive projection of the magnet 27 in the axial direction of the handle 3, thereby making the Hall switch 311 as close to the magnet 27 as possible in the axial direction of the handle 3, thereby ensuring the sensing effect of the Hall switch 311 and avoiding the situation where the Hall switch 311 cannot be triggered when the fluid connection assembly 2 is installed in place.

[0070] In one embodiment of the present disclosure, reference Figure 7The clamp head 21 is provided with a groove, and the magnet 27 is located in the groove and is configured to be sealed in the groove by glue injection. The magnet 27 is sealed inside the clamp head 21 by glue injection, thereby achieving waterproofing of the magnet 27. This embodiment prevents the magnet 27 from oxidizing and rusting when in contact with the fluid, ensures the magnetic force of the magnet 27, and thus ensures that the Hall switch 311 can accurately identify.

[0071] In one embodiment of the present disclosure, reference Figure 4 and Fig. 9 , the adapter cavity 330 is constructed as a cylindrical cavity, the clamp head 21 is constructed as a cylinder coaxial with the adapter cavity 330, and the clamp head 21 is constructed to be detachably connected in the adapter cavity 330. When in the installed state, the clamp head 21 is constructed to be able to rotate freely relative to the adapter cavity 330. Specifically, the engaging groove 211 on the clamp head 21 can be constructed as an annular surface, and the matching end surface of the locking member 4 and the engaging groove 211 can be constructed as an arc surface that matches therewith, so that the clamp head 21 can rotate freely relative to the adapter cavity 330. When the user uses the handle 3 to flush the teeth, he will not be restricted by the position of the water pipe 11 and the body 1, and can freely and flexibly rotate the handle 3 to flush the teeth, which improves the user experience.

[0072] In one embodiment of the present disclosure, the magnet 27 is constructed as an annular magnet 27 coaxial with the chuck 21, and the magnet 27 is configured to trigger the Hall switch 311 when the chuck 21 is at any installation angle. The chuck 21 can be installed into the adapter cavity 330 at any angle and can rotate freely in the adapter cavity 330. In order to ensure that the Hall switch 311 fixedly set at a single-side position in the inner cavity 320 can always be accurately triggered, the magnet 27 is constructed in an annular shape in this embodiment. When the chuck 21 rotates freely in the adapter cavity 330, the sensing area of ​​the Hall switch 311 and the positive projection of the annular magnet 27 in the axial direction of the handle 3 always maintain at least partial overlap, so that the recognition effect of the Hall switch 311 is not limited by the installation and use direction.
