DETAILED DESCRIPTION

[0050] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0051] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0052] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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 configured to be detachably connected to the handle. The fluid connection component is used to deliver water to 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.

[0058] One of the handle and the fluid connection assembly includes a first connection component with a first axis and a first fluid passage, and the other includes a second connection component with a second axis, a second fluid passage, and a transition cavity. The first connection component can extend into the transition cavity and cooperate with the second connection component to assemble the handle and the fluid connection assembly together.

[0059] Specifically, when the first axis and the second axis are in the same straight line and the first connecting component and the second connecting component move toward each other, the first connecting component and the second connecting component are configured to move to a connected state. The first connecting component and the second connecting component can engage with each other during the coaxial movement toward each other, or can be connected to each other in other forms, thereby achieving a structural connection between the handle and the fluid connection assembly.

[0060] In the connected state, the adapter cavity is configured to at least partially accommodate the fluid connection assembly or the handle. It is understandable that when the adapter cavity is located on the handle, the adapter cavity can at least partially accommodate the fluid connection assembly; when the adapter cavity is located on the fluid connection assembly, the adapter cavity can at least partially accommodate the handle. The first fluid passage and the second fluid passage are connected to provide a water connection between the handle and the fluid connection assembly. When the handle and the fluid connection assembly are installed together, the water path between the two is connected, and the external fluid can flow into the handle through the fluid connection assembly, so that the handle can achieve the function of flushing teeth.

[0061] When a decoupling force greater than a threshold is applied to the first connecting part or the second connecting part, the first connecting part and the second connecting part are separated from each other and are configured to move to a decoupling state. At this time, the water path between the handle and the fluid connection assembly is disconnected, and the external fluid cannot be delivered to the handle. At this time, the handle cannot be used for flushing teeth, but can be used as a toothbrush.

[0062] The present disclosure realizes quick and accurate disassembly and assembly of the handle by respectively providing a first connection component and a second connection component on the handle and the fluid connection component, and connecting the water path between the handle and the fluid connection component when the two are connected. For the oral care device provided by the present disclosure, when the user removes the handle from the fluid connection component, the water path will be disconnected, and the user can use the handle as a toothbrush or an electric toothbrush; when the user connects the handle to the fluid connection component, the water path will be connected, and the user can use the handle as a water flosser.

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.

[0067] refer to Figure 3 , Figures 11 to 13 , one of the handle 3 and the fluid connection assembly 2 includes a first connection component 21 having a first axis and a first fluid passage, and the other includes a second connection component having a second axis, a second fluid passage 3212, and a transition cavity 330. In a specific embodiment of the present disclosure, the fluid connection assembly 2 includes a first connection component 21 and a first fluid passage, and the handle 3 includes a second connection component, a second fluid passage 3212, and a transition cavity 330. The first connection component 21 can extend into the interior of the transition cavity 330 and cooperate with the second connection component, so that the handle 3 and the fluid connection assembly 2 are assembled together.

[0068] refer to Figure 3 and Fig.11 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, and a first fluid passage is formed between the connection assembly inlet 24 and the connection assembly outlet 26. The connection assembly inlet 24 can be connected to the water pipe 11, and the fluid can flow into the fluid connection assembly 2 from the connection assembly inlet 24. When the handle 3 is installed in place, the fluid can flow out of the fluid connection assembly 2 from the connection assembly outlet 26 and then flow into the handle 3.

[0069] 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 the fluid storage chamber is configured to communicate with the first fluid passage or the second fluid passage 3212 of the fluid connection component 2. 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 fluid connection component 2 can be connected to the fluid storage chamber inside the body 1 through a water pipe 11. 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 to perform tooth flushing.

[0070] 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.

[0071] refer to Figure 3 and Fig.12 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 support components inside the handle 3, such as a battery, a motor, and a mainboard 31. The side of the mounting bracket 32 ​​close to the care head 30 is enclosed with the housing 36 to form a closed inner cavity 320. 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.

[0072] 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.

[0073] When the first axis and the second axis are in the same straight line, and the first connecting part 21 and the second connecting part move toward each other, the first connecting part 21 and the second connecting part are configured to move to a connected state. The first connecting part 21 and the second connecting part can engage with each other during the coaxial movement toward each other, or be connected to each other in other forms, thereby realizing the structural connection between the handle 3 and the fluid connection assembly 2. When a decoupling force greater than a threshold is applied to the first connecting part 21 or the second connecting part, the first connecting part 21 and the second connecting part are separated from each other and configured to move to a decoupling state.

[0074] The structural connection and decoupling between the first connection component 21 and the second connection component can have various forms, which are not limited in the present disclosure. A specific implementation is provided below for realizing quick disassembly and quick assembly between the handle 3 and the fluid connection assembly 2.

[0075] In one embodiment of the present disclosure, reference Figure 3 , Figure 4 , Figure 8 and Fig.12The second connection component includes a fixing component 33 and a locking component 4 movably connected to the fixing component 33. The transition cavity 330 is arranged inside the fixing component 33, and the first connection component 21 can extend into the transition cavity 330. The transition cavity 330 is configured to at least partially accommodate the fluid connection component 2. The locking component 4 can lock the first connection component 21, so that the fluid connection component 2 and the handle 3 are assembled together.

[0076] refer to Fig. 9 and Fig.10 , in the connected state, such as Fig. 9 As shown, the locking member 4 is configured to cooperate with the first connecting member 21 to provide a retaining force. Figure 3 As shown, the first connecting member 21 is provided with a snap-fitting groove 211, and the locking member 4 is configured to cooperate with the snap-fitting groove 211, so as to lock the first connecting member 21 in the adapter cavity 330. Fig.10 As shown, when a decoupling force greater than a threshold is applied to the locking member 4 , the locking member 4 is configured to move relative to the fixing member 33 to be separated from the first connecting component 21 .

[0077] The specific structure and working mode of a locking member 4 provided in this embodiment will be described in detail below.

[0078] In one embodiment of the present disclosure, reference Figure 6 and Figure 7 The locking member 4 includes a pushing portion 41 and a clamping portion 42 respectively arranged on both sides of the pushing portion 41, and the two clamping portions 42 enclose a clamping area for clamping the first connecting member 21. The pushing portion 41 and the clamping portion 42 can be integrally formed, and when the pushing portion 41 is subjected to an external force, the clamping portion 42 can be driven to move together. Specifically, when the pushing portion 41 is subjected to an external force and moves on the X-axis, the two clamping portions 42 move away from each other to disengage from the first connecting member 21; and when the pushing portion 41 is reset, the two clamping portions 42 move toward each other to cooperate with the first connecting member 21, that is, clamped on the clamping groove 211.

[0079] refer to Figure 2 , Figure 4 and Fig.13 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 of the handle 3. When the user pushes the button 35, the lock member 4 can move from the locked position to the unlocked position, so that the fluid connection assembly 2 can be easily detached from the handle 3. Specifically, the button 35 abuts against the push portion 41. When the user pushes the button 35, the button 35 can apply a pushing force in the X-axis direction to the push portion 41, so that the push portion 41 drives the two engaging portions 42 to move away from each other to achieve unlocking.

[0080] When the external force is removed, the button 35 can be reset under the elastic force of the spring 34. Figure 8 A guide column 334 is provided on the fixing member 33, referring to Figure 7 , a through hole 411 may be provided on the pushing portion 41. Fig.12 As shown, the spring 34 passes through the through hole 411 and is sleeved on the guide column 334, so as to be pre-pressed between the fixing member 33 and the button 35. When the user pushes the button 35, the button 35 will compress the spring 34 to store energy so as to reset when the external force is removed. The present disclosure realizes easy control of the lock member 4 to move between the open position and the locked position by setting the button 35, thereby realizing the rapid disassembly and assembly between the fluid connection assembly 2 and the handle 3.

[0081] In one embodiment of the present disclosure, reference Figures 6 to 8 The first guide surface 420 is provided on the engaging portion 42, and in the direction from away from the pushing portion 41 to close to the pushing portion 41, the first guide surface 420 is configured to gradually tilt toward the X-axis direction; the fixing member 33 is provided with a second guide surface 331 that cooperates with the first guide surface 420. When the pushing portion 41 is subjected to an external force and moves on the X-axis, the first guide surface 420 is configured to be squeezed by the second guide surface 331, so as to push the engaging portion 42 to open the clamping area in a manner of moving away from each other.

[0082] Specifically, the first guide surface 420 is arranged in parallel with the second guide surface 331, and when the pushing portion 41 is subjected to an external force in the X-axis direction, the first guide surface 420 can slide along the second guide surface 331. Since the two first guide surfaces 420 are inclined in a direction away from each other along the pushing direction, the first guide surface 420 will be squeezed by the second guide surface 331 during the sliding process, so that the two engaging portions 42 are moved away from each other to open the clamping area.

[0083] In one embodiment of the present disclosure, reference Figure 6 and Figure 7 The clamping portion 42 includes support arms 421 connected to both sides of the pushing portion 41, and clamping arms 422 respectively connected to the support arms 421, and the two clamping arms 422 enclose a clamping area. The two clamping arms 442 are used to cooperate with the clamping groove 211, and the two support arms 421 are used to connect the two clamping arms 422 to the pushing portion 41. In addition, the support arms 421 also provide a certain space for the deformation of the locking member 4.

[0084] Specifically, Figure 6As shown, with the position where the clamping arm 422 and the support arm 421 are connected as the boundary, the clamping arm 422 is constructed to have a first portion 4221 adjacent to the pushing portion 41, and a second portion 4222 away from the pushing portion 41. The first guide surface 420 is configured to be arranged at the end of the first portion 4221, and the first guide surface 420 is configured to be squeezed by the second guide surface 331 to push the support arm 421 to deform in a direction away from each other, so as to open the clamping area of ​​the clamping arm 422.

[0085] When the first guide surface 420 is squeezed by the second guide surface 331, the first parts 4221 move away from each other, thereby driving the support arm 421 and the second part 4222 connected thereto to move away from each other. The moving away of the second parts 4222 opens the clamping area. The moving away of the support arms 421 causes the locking member 4 to undergo elastic deformation. When the external force is removed, the locking member 4 can return to the locked position under the action of the elastic restoring force.

[0086] Furthermore, there is a gap 423 between the first portion 4221 and the corresponding position of the support arm 421. The gap 423 makes the support arm 421 present an elongated shape, and the support arm 421 is more easily deformed when subjected to external force, so that the user does not need to spend too much effort to press the button 35, but only needs to press it lightly to unlock.

[0087] In one embodiment of the present disclosure, reference Figures 7 to 10 The second part 4222 and the corresponding position of the supported arm 421 form a guide groove 424, and the fixing member 33 is provided with a guide portion 332. When the locking member 4 moves relative to the fixing member 33, the guide portion 332 is configured to slide along the guide groove 424. Specifically, a through groove 333 is provided on the side wall of the fixing member 33, and the clamping arm 422 is configured to cooperate with the through groove 333. The guide portion 332 is provided on the outer wall of the fixing member 33, and is configured to restrict the clamping arm 422 within the through groove 333.

[0088] like Fig. 9 and Fig.10 As shown, during the whole process of the movement of the lock member 4, the guide groove 424 is always matched with the guide portion 332. The guide portion 332 plays a role of guiding and limiting, and the lock member 4 can only slide along a fixed direction under the action of the guide portion 332, preventing the lock member 4 from tilting to other positions during the movement.

[0089] In one embodiment of the present disclosure, reference Fig.14The edge of the end of the first connecting member 21 is configured as an inclined installation guide surface 212; the engaging portion 42 is provided with an installation mating surface 425, which is configured to be parallel to the installation guide surface 212. The installation mating surface 425 and the installation guide surface 212 can provide mutual guidance. When the user assembles the handle 3 and the fluid connection component 2, there is no need to press the button 35, but the fluid connection component 2 can be directly and quickly inserted into the transfer cavity 330. The installation guide surface 212 can slide with the installation mating surface 425, squeeze the engaging portion 42, and open the clamping area, so that the fluid connection component 2 can be conveniently and quickly installed on the handle 3.

[0090] In the connected state, the first fluid passage and the second fluid passage in the fluid connection component 2 and the handle 3 are connected to provide a water connection between the handle 3 and the fluid connection component 2. When the handle 3 and the fluid connection component 2 are installed together, the water path between the two is connected, and the external fluid can flow into the handle 3 through the fluid connection component 2, so that the handle 3 can achieve the function of flushing teeth. When the fluid connection component 2 is separated from the handle 3, the water path between the handle 3 and the fluid connection component 2 is disconnected, and the external fluid cannot be delivered to the handle 3. At this time, the handle 3 cannot be used for flushing teeth, but can be used as a toothbrush.

[0091] In one embodiment of the present disclosure, reference Figure 5 , Figures 11 to 13 The fluid connection assembly 2 is provided with a valve assembly, which is configured to seal the first fluid passage in a natural state. The valve assembly includes a sealing plug 22 and an elastic member 23, which may be a spring. Fig.11 As shown, the sealing plug 22 is constructed to seal the first fluid passage when the elastic member 23 is in a natural state. Specifically, the fluid connection component 2 includes a main body 20, and the valve assembly can be arranged inside the main body 20 of the fluid connection component 2. The sealing plug 22 has a tendency to move upward under the elastic force of the elastic member 23, thereby sealing the connection component outlet 26.

[0092] like Fig.12 As shown, the handle 3 includes a transfer cavity 330, a water intake portion 321 extending into the transfer cavity 330, and a second fluid passage 3212 is provided in the water intake portion 321. Fig.13 As shown, in the connected state, the water intake portion 321 is configured to apply an unsealing force to the valve assembly to connect the first fluid passage and the second fluid passage 3212. Specifically, the water intake portion 321 is configured to push the sealing plug 22 to open the water flow passage between the handle 3 and the fluid connection assembly 2, so that the first fluid passage and the second fluid passage 3212 are connected.

[0093] In the decoupled state, the water intake portion 321 is separated from the valve assembly to reset the valve assembly. At this time, the water intake portion 321 is separated from the sealing plug 22, and the sealing plug 22 is configured to 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 reset under the elastic force to seal the connection assembly outlet 26 again.

[0094] In a specific embodiment of the present disclosure, Fig.12 As shown, the water intake portion 321 is provided with a water intake hole 3211, and the water intake hole 3211 can be specifically provided on the side wall of the water intake portion 321. Fig.13 As shown, when the water intake portion 321 pushes the sealing plug 22, the fluid can flow into the second fluid passage 3212 through the water intake hole 3211. The upper end of the second fluid passage 3212 can be connected to the water channel inside the handle 3, so that the fluid flows to the nozzle of the care head 30 for spraying.

[0095] In a specific embodiment of the present disclosure, Fig.11 As shown, an elastic waterproof ring 25 is provided near the sealing plug 22 in the fluid connection component 2. When the water intake portion 321 extends from the connection component outlet 26 into the first fluid channel 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 in the first fluid channel can only flow into the second fluid passage 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.

[0096] The present disclosure realizes a one-way sealed connection assembly outlet 26 by arranging a valve assembly in the fluid connection assembly 2. The first fluid channel 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.

[0097] The present disclosure achieves quick and accurate assembly and disassembly of the handle 3 by respectively providing a first connection component 21 and a second connection component on the handle 3 and the fluid connection component 2, and connecting the water path between the handle 3 and the fluid connection component 2 when the two are connected. For the oral care device provided by the present disclosure, when the user removes the handle 3 from the fluid connection component 2, the water path will be disconnected, and the user can use the handle 3 as a toothbrush or an electric toothbrush; when the user connects the handle 3 to the fluid connection component 2, the water path will be connected, and the user can use the handle 3 as a water flosser.

[0098] In one embodiment of the present disclosure, in the connected state, the fluid connection assembly 2 or the handle 3 is configured to be rotatable relative to the adapter cavity 330. Fig.14 The engaging groove 211 is constructed as a circular groove coaxial with the adapter cavity 330, and the position of the locking member 4 for cooperating with the engaging groove 211 is constructed as an arc structure adapted to the shape of the engaging groove 211. In this way, in the connected state, the fluid connection assembly 2 can rotate freely relative to the handle 3, and when the user uses the handle 3 to flush teeth, he will not be restricted by the position of the water pipe and the body, but can freely and flexibly rotate the handle 3 to flush teeth, thereby improving the user experience.

[0099] In one embodiment of the present disclosure, reference Fig.11 , a magnet 27 is provided in the fluid connection assembly 2. When the first axis and the second axis are in the same straight line, and the first connection member 21 and the second connection member move toward each other, the magnet 27 is configured to be located at one end close to the handle 3. Correspondingly, Figure 4 As shown, a Hall switch 311 is provided on one end of the main board 31 adjacent to the transfer cavity 330. When the fluid connection assembly 2 and the handle 3 are installed in place, the Hall switch 311 can be triggered by the magnet 27, thereby accurately identifying whether the handle is connected to the water source and whether the waterway is unobstructed.

[0100] Among them, the magnet 27 can be set in the fluid connection component 2 at one end as close to the Hall switch 311 as possible, and the Hall switch 311 can be set at one end as close to the magnet 27 as possible, so that the Hall switch 311 is 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 component 2 is installed in place.

[0101] Embodiment 2

[0102] This embodiment also provides an oral care device. The difference between this embodiment and the first embodiment is only in the specific structure and movement mode of the locking member 4. The other parts are completely consistent with the first embodiment and will not be repeated here.

[0103] refer to Fig.15 and Fig.16 The lock member 4 is constructed in an annular shape, and has a pushing portion 41 and a clamping portion 42 on opposite sides. The pushing portion 41 is constructed so that when it is subjected to an external force and moves on the X-axis, the clamping portion 42 moves along the X-axis to disengage from the first connecting member 21, and when the pushing portion 41 is reset, the clamping portion 42 moves along the X-axis to cooperate with the first connecting member 21.

[0104] When the handle 3 and the fluid connection assembly 2 are installed together, the engaging portion 42 can extend into the engaging groove 211 on the first connection member 21, thereby playing a fixing role. The pushing portion 41 can drive the entire annular locking member 4 to move along the X-axis under the action of external force, thereby driving the engaging portion 42 to move to a position away from the engaging groove 211 until it is separated from the engaging groove 211, and the user can easily disassemble the handle 3 from the fluid connection assembly 2.

[0105] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
