Description

Technical Field

[0001] This invention relates to the field of oral care technology, and more particularly to an oral care device. Background Technology

[0002] As people pay more attention to oral care, electric toothbrushes and water flossers have gradually become common oral care tools in households.

[0003] Currently available electric toothbrushes can perform both brushing and rinsing functions. Accordingly, electric toothbrushes typically have multiple drive components. One drive component is a motor, which drives the brush head to vibrate or oscillate to achieve the brushing function. Another drive component is usually a pump, which drives the flow of cleaning fluids such as water to achieve the rinsing function.

[0004] However, the presence of multiple drive components in an electric toothbrush results in a higher manufacturing cost. Summary of the Invention

[0005] In view of the above problems, embodiments of the present invention provide an oral care device that can solve the problem that setting multiple drive components in an electric toothbrush will lead to a high manufacturing cost of the electric toothbrush.

[0006] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0008] In some embodiments, the vector transmission rod has a drive segment with varying radial lengths at different circumferential positions on the outer wall of the drive segment; the fluid regulating unit abuts against the drive segment and is configured to contact different local portions of the outer wall of the drive segment when the drive segment oscillates about its own axis, so that the fluid regulating unit switches between a fluid-connected state and a fluid-cut-off state.

[0009] In some embodiments, the outer wall of the drive section has a retaining surface and a lifting surface, the retaining surface and the lifting surface being connected in the circumferential direction of the drive section; the outer diameter of the retaining surface is equal at different positions in the circumferential direction of the vector transmission rod, and the fluid adjustment unit is in a fluid cut-off state when the retaining surface abuts against the switching member; from the side closer to the retaining surface to the side farther away from the retaining surface, the value of the outer diameter of the lifting surface gradually increases or gradually decreases.

[0010] In some embodiments, the lifting surface is a plane, and the lifting surface and the holding surface are smoothly connected.

[0011] In some embodiments, the fluid regulating unit includes an regulating body and a switching element. The regulating body has a transition section, within which a transition space is constructed. The fluid regulating unit also includes a sealing element that can be opened and closed to seal a first end of the transition space. The sealing end of the switching element is located at a second end of the transition space and is configured to extend into or out of the transition space under the action of the vector transmission rod. The sealing element is configured to open the first end of the transition space under the fluid pressure when the sealing end of the switching element is displaced toward a side closer to the sealing element.

[0012] In some embodiments, the cover is a self-recovering member configured to restore its shape, the cover covering the end face of the first end of the transition space; or, the cover extending into the transition space, the circumferential sidewall of the cover abutting against the inner wall of the first end of the transition space; and / or, the switching member includes a switching member body and a blocking portion, the blocking portion being connected to the end of the switching member body away from the vector transmission rod, the blocking portion being an elastic member.

[0013] In some embodiments, the fluid regulating unit includes a first self-resetting element, which connects the cover and the regulating body. The cover seals the first end of the transition space under the self-resetting force of the first self-resetting element.

[0014] In some embodiments, the fluid regulating unit includes a second self-resetting element, which connects the switching element and the regulating body. The switching element presses against the vector transmission rod under the self-resetting force of the first self-resetting element.

The inner cavities of the first guide section and the second guide section are both in communication with the transition space, and the first guide section and the second guide section are respectively located upstream and downstream of the fluid medium flow direction. The inner cavity of the first guide section is in communication with the medium supply unit, and the inner cavity of the second guide section is in communication with the medium delivery channel.

[0016] In some embodiments, the medium delivery channel extends through both ends of the vector transmission rod along its axial direction, and the second guide section is rotatably connected to the end of the vector transmission rod away from the composite component.

The oral care device also includes a fluid regulation unit, which can change the on / off state of the fluid medium under the action of the vector transmission rod. The vector transmission rod has a medium delivery channel; when the fluid is in a fluid-connected state, the fluid medium can be delivered to the composite component via the fluid regulation unit and the medium delivery channel. In other words, the embodiments of this application can drive the composite component or simultaneously drive both the composite component and the fluid medium through a single driving component of the vector generation unit, resulting in lower manufacturing costs and lower power consumption for the oral care device.

[0037] To make the above-mentioned objectives, features, and advantages of the embodiments of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] As described in the background section, electric toothbrushes in the related art typically have multiple drive components, one for driving the brush head and another for driving the cleaning fluid to achieve brushing and rinsing functions, respectively. However, this also results in higher manufacturing costs and higher power consumption for electric toothbrushes.

[0039] To address the aforementioned technical problems, this application provides an oral care device, including a composite component and a vector generation unit for driving the composite component. The vector generation unit has a vector transmission rod with a media delivery channel. The oral care device also includes a fluid regulation unit, which can change the on / off state of the fluid medium under the action of the vector transmission rod. When the fluid is in a fluid-connected state, the fluid medium can be delivered to the composite component via the fluid regulation unit and the media delivery channel. In other words, this embodiment can drive the composite component or simultaneously drive both the composite component and the fluid medium using only one driving component of the vector generation unit. This results in lower manufacturing costs and lower power consumption for the oral care device.

[0040] Please see Figure 1 and Figure 2 This embodiment provides an oral care device 10, which includes an unbalanced housing 100 and a composite component 200, a media supply unit 300, and a vector generation unit 400 disposed on the unbalanced housing 100. The media supply unit 300 and the vector generation unit 400 are disposed within the unbalanced housing 100, thus providing protection for the media supply unit 300 and the vector generation unit 400 through the unbalanced housing 100.

[0041] The unbalanced housing 100 can be made of plastic, making it lightweight and easy to hold.

[0042] The unbalanced housing 100 is constructed with a biomimetic grip surface suitable for holding; that is, the outer wall surface of the unbalanced housing 100 is a biomimetic grip surface. Biomimicry refers to its applicability to the shape of a user's hand when gripping the unbalanced housing 100. In other words, when a user grips the unbalanced housing 100, the outer wall surface of the unbalanced housing 100 can contact different positions of the user's hand, resulting in higher user comfort when using the oral care device 10. For example, the unbalanced housing 100 has recessed structures corresponding to the user's fingers.

[0043] The unbalanced shell 100 has a main extension line 110, along which it extends. In other words, the main extension line 110 can be understood as the length direction of the unbalanced shell 100. The unbalanced shell 100 is approximately a rod-shaped structural member with a predetermined length in the direction of the main extension line 110. Correspondingly, in the direction of the main extension line 110, the unbalanced shell 100 has two opposing ends.

[0044] Here, "unbalanced" refers to a non-rotationally symmetric structure, that is, the unbalanced shell 100 is a non-rotationally symmetric shell, which is adapted to the grip shape of the user's hand and improves the user's comfort.

[0045] In some embodiments, the biomimetic grip surface includes a first contoured grip surface 130 and a second contoured grip surface 140 that are asymmetrically distributed relative to the main extension line 110, and the first contoured grip surface 130 and the second contoured grip surface 140 are joined together to form a closed annular surface.

[0046] The first contoured grip surface 130 and the second contoured grip surface 140 can have similar shapes, for example, both being approximately cylindrical, resulting in a relatively simple structure. Furthermore, the first contoured grip surface 130 and the second contoured grip surface 140 are arranged asymmetrically about the main extension line 110. For example, the distance between the first contoured grip surface 130 and the main extension line 110 is greater than the distance between the second contoured grip surface 140 and the main extension line 110, so that they form a complete toroidal structure.

[0047] The vector generation unit 400 includes a vector transmission rod 410, which is a rod-shaped structure and receives the composite component 200. By connecting the composite component 200 to the vector transmission rod 410, the composite component 200 can be driven to oscillate around the axis of the vector transmission rod 410. The vector generation unit 400 also includes a power component, which can be understood as the power unit of the oral care device 10. The power component outputs a motion vector, and the vector transmission rod 410 is connected to the drive shaft of the power component to transmit the motion vector to the composite component 200.

[0048] The composite component 200 and the vector transmission rod 410 are detachably connected, for example, by snap-fit, which makes it convenient for users to replace the composite component 200.

[0049] The composite component 200 is installed at one end of the unbalanced housing 100 along the main extension line 110 and is configured to remove foreign objects in the target area. That is, the composite component 200 is installed at one end of the unbalanced housing 100 along the length direction, and the target area is the inside of the user's oral cavity.

[0050] Depending on the 200 types of composite components and the different usage modes, the oral care device 10 can have different modes, such as a brushing mode and a mixed mode that can perform brushing and flossing simultaneously.

[0051] In some embodiments, the composite component 200 can be a toothbrush head or a nozzle. When the user needs to brush their teeth, the toothbrush head can be mounted on the vector transmission rod 410; when the user needs to rinse their teeth, the nozzle can be mounted on the vector transmission rod 410. With this configuration, a toothbrush / water flosser combination system can be realized through a set of vector generation unit 400 and media supply unit 300, which can realize both brushing and rinsing functions.

[0052] The media supply unit 300 is configured to provide the composite component 200 with a fluid medium that accelerates the removal of foreign matter. In some embodiments, the media supply unit 300 is a media container for storing the fluid medium.

[0053] The medium container can be independent of the unbalanced housing 100, that is, the medium container and the unbalanced housing 100 are two independent components. In some embodiments, an internal wall 120 may also be provided inside the unbalanced housing 100 to divide the inner cavity of the unbalanced housing 100 into two independent cavities, one of which constitutes the medium container for storing fluid medium, and the other part is used to install the power components of the vector generation unit 400, etc., making the oral care device 10 easy to carry.

[0054] The fluid medium can be a liquid or a gas. When the fluid medium is a liquid, it can be water or a liquid mixed with cleaning agents, disinfectants, or other substances.

[0055] In some embodiments, the vector generation unit 400 and the medium container can be arranged along the main extension line 110 of the oral care device 10, with the medium container located at the end of the vector generation unit 400 away from the composite member 200 or on the side of the vector generation unit 400. Thus, compared to the prior art where the pumping assembly is housed within the housing, this embodiment can reduce the size of the oral care device 10 or increase the volume of the medium solution.

[0056] For the vector generation unit 400, depending on the different operating modes of the oral care device 10, the motion vector of the vector generation unit 400 includes, but is not limited to, vibration, oscillation, etc.

[0057] In some embodiments, the vector generation unit 400 is at least partially added within the unbalanced housing 100, that is, part of the vector generation unit 400 is located inside the unbalanced housing 100 and part of the vector generation unit 400 is located outside the unbalanced housing 100. The vector generation unit 400 located outside the unbalanced housing 100 extends to the outside of the unbalanced housing 100 and is connected to the composite member 200 to provide motion vectors to the composite member 200.

[0058] In some embodiments, to protect the power component, the power component is typically located inside the unbalanced housing 100. The vector transmission rod 410 spans the inner and outer sides of the unbalanced housing 100. One end of the vector transmission rod 410 located inside the unbalanced housing 100 is connected to the power component, and the other end of the vector transmission rod 410 located outside the unbalanced housing 100 is used to connect to the composite component 200. In this way, the motion vector output by the power component can be transmitted to the composite component 200 through the vector transmission rod 410.

[0059] In some embodiments, the power component in the vector generation unit 400 can output eccentric power, and the vector transmission rod 410 is connected to the drive shaft of the power component to transmit the eccentric power to the vector transmission rod 410, thereby causing the composite component 200 to vibrate or oscillate relative to the target area.

[0060] For example, the vector generation unit 400 provided in this application embodiment can be a miniature reciprocating oscillator, such as a sonic motor, whose power components include a drive shaft, a stator and a rotor, wherein the stator includes a fixedly disposed permanent magnet, the drive shaft is inserted into the rotor, and an iron core block is sleeved on the drive shaft, the iron core block is located inside the permanent magnet, and the iron core block is wound with a coil winding.

[0061] When the coil winding is forward-energized, the coil winding of the iron core block forms a magnetic field. This magnetic field interacts with the magnetic field of the permanent magnet, causing the rotor to swing counterclockwise by a certain angle. Conversely, when the coil winding is reverse-energized, the magnetic field formed by the coil winding of the iron core block is in the opposite direction to the previous magnetic field. This magnetic field interacts with the magnetic field of the permanent magnet, causing the rotor to swing counterclockwise by a certain angle. When the coil is alternately energized in both forward and reverse directions at a preset frequency, the rotor will swing back and forth at this frequency. In the unenergized state, the iron core block, balanced by the attractive forces between the opposing magnetic poles of the permanent magnet, will be positioned at the midpoint between the two poles.

[0062] In some embodiments, for connecting the medium supply unit 300 and the composite member 200, the vector transmission rod 410 has a medium delivery channel 411, that is, at least a portion of the interior of the vector transmission rod 410 is hollow along its length to form a medium delivery channel 411 for the flow of fluid medium. The medium delivery channel 411 communicates with the composite member 200, so that the fluid medium can be delivered to the location of the composite member 200 via the medium delivery channel 411.

[0063] The centerline of the media delivery channel 411 is arranged on the main extension line 110. That is to say, the centerline of the media delivery channel 411 is used as the main extension line 110 of the oral care device 10, and the unbalanced housing 100 is arranged around the outside of the vector transmission rod 410.

[0064] Correspondingly, the composite component 200 may be provided with a medium guiding channel 210 that is connected to the medium conveying channel 411. In some embodiments, the center line of the medium guiding channel 210 coincides with the center line of the medium conveying channel 411, so that the composite component 200 installed on the vector transmission rod 410 can be located on the same straight line as the vector transmission rod 410, which can improve the vector efficiency of the vector transmission rod 410 to the composite component 200 and avoid vector loss.

[0065] In other words, the composite component 200 is not only equipped with brush bristles 220 for brushing teeth, but also with splash holes 230 that are connected to the medium guiding channel. This means that users can brush their teeth, rinse their teeth, or brush their teeth and rinse their teeth at the same time through the same composite component 200, thereby simplifying the structure of the oral care device 10.

[0066] The axis of the drive shaft of the power component can be spaced apart from the vector transmission rod 410. For example, the drive shaft of the power component can be located on one side of the vector transmission rod 410, and a power adapter is provided between the two to realize the transmission of power.

[0067] In some embodiments, the end of the vector transmission rod 410 away from the composite member 200 enters the vector generation unit 400 from the end of the vector generation unit 400 near the composite member 200, and exits the vector generation unit 400 from the end of the vector generation unit 400 away from the composite member 200. That is, the vector transmission rod 410 passes through the power component of the vector generation unit 400 and is connected to the drive shaft of the power component.

[0068] This reduces the size occupied by the vector generation unit 400 within the unbalanced housing 100 and reduces the circumferential size of the oral care device 10, making it easier for the user to grip.

[0069] In some embodiments, the oral care device 10 further includes a fluid adjustment unit 500, which is connected to the vector transmission rod 410 and is disposed between the media delivery channel 411 and the media supply unit 300.

[0070] Furthermore, the fluid regulating unit 500 is configured to change the on / off state of the fluid medium under the drive of the vector transmission rod 410. In other words, the function of the fluid regulating unit 500 is to change the on / off state of the fluid medium. Accordingly, the fluid regulating unit 500 has two working states: fluid connection state and fluid cut-off state.

[0071] When the fluid regulating unit 500 is in a fluid communication state, the fluid medium is configured to be transported through the fluid regulating unit 500 to the medium transport channel 411 and discharged from the composite component 200. Understandably, at this time, the vector generation unit 400 drives the vector transmission rod 410 and the composite component 200 to swing, meaning the oral care device 10 is in a mixed mode, allowing the user to perform brushing operations, or simultaneously brushing and rinsing operations.

[0072] When the fluid regulating unit 500 is in the fluid cut-off state, the medium delivery channel 411 and the medium supply unit 300 are disconnected, and the fluid medium cannot be discharged through the medium delivery channel 411 and the composite component 200. At this time, the oral care device 10 can be in brushing mode or in the off state.

[0073] Meanwhile, during the swinging process of the vector transmission rod 410, the fluid adjustment unit 500 can switch between two working states: fluid connection state and fluid cut-off state. Correspondingly, the oral care device 10 switches between different usage modes.

[0074] In other words, the vector generation unit 400 can both drive the composite component 200 to swing and drive the fluid medium to flow. The oral care device 10 changes its working state through a driving component. Compared with the related technology, which requires the simultaneous setting of multiple driving components, the oral care device 10 provided in this embodiment can be smaller in size and has lower manufacturing cost and power consumption.

[0075] In order to change the working state of the fluid regulating unit 500 by swinging the vector transmission rod 410, the fluid regulating unit 500 can be an electromagnetic check valve. The opening and closing of the electromagnetic check valve can be controlled by swinging the vector transmission rod 410 at different angles.

[0076] In some embodiments, please refer to Figures 2 to 5The vector transmission rod 410 has a driving section 412, which can be located at any position on the vector transmission rod 410, for example, at the end of the vector transmission rod 410 away from the composite component 200. The radial length of the outer wall surface of the driving section 412 is not equal at different circumferential positions, that is, the outer wall surface of the driving section 412 is a non-cylindrical surface, and the outer diameter of the outer wall surface of the driving section 412 is different at different positions, for example, the outer wall surface of the driving section 412 is a parabolic cylinder.

[0077] In some embodiments, the fluid regulating unit 500 abuts against the drive section 412, that is, the fluid regulating unit 500 rests against the drive section 412, and there are no other direct connecting components between the fluid regulating unit 500 and the drive section 412, resulting in a relatively simple structure.

[0078] Furthermore, the fluid regulating unit 500 is configured to contact different local parts of the outer wall surface of the drive section 412 when the drive section 412 swings around its own axis. That is, during the swing of the vector transmission rod 410, the fluid regulating unit 500 is in a relatively stationary state relative to the unbalanced housing 100. In this way, different parts of the outer wall surface of the drive section 412 can rotate to the position of the fluid regulating unit 500 and abut against the fluid regulating unit 500.

[0079] Because the outer diameter is different at different positions on the outer wall of the drive section 412, the fluid regulating unit 500 as a whole or part of the fluid regulating unit 500 will be offset relative to the vector transmission rod 410, so that the fluid regulating unit 500 switches between the fluid connection state and the fluid cut-off state.

[0080] In this embodiment, the working state of the fluid regulating unit 500 is changed through the mechanical transmission structure between the vector transmission rod 410 and the fluid regulating unit 500, which has high reliability and low power consumption.

[0081] In some embodiments, the outer wall surface of the drive segment 412 has a retaining surface 4121 and a lifting surface 4122, which are connected in the circumferential direction of the drive segment 412, that is, the retaining surface 4121 and the lifting surface 4122 are connected and are located at different positions in the circumferential direction of the drive segment 412.

[0082] In some embodiments, the outer diameter of the retaining surface 4121 is equal at different circumferential positions of the vector transmission rod 410. For example, the retaining surface 4121 can be a cylindrical surface, and the outer diameter of the retaining surface 4121 is the same at different positions. In this embodiment, the circumferential extension length of the retaining surface 4121 along the driving segment 412 is not further limited, as long as the swing amplitude of the composite component 200 is less than or equal to the circumferential extension length of the retaining surface 4121 along the driving segment 412 in the brushing mode.

[0083] In this way, when the vector transmission rod 410 is swinging around its own axis and the switching member 520 is in contact with the holding surface 4121, the fluid adjustment unit 500 as a whole or part of the fluid adjustment unit 500 will not be stretched or offset relative to the vector transmission rod 410. The fluid adjustment unit 500 maintains its current working state, that is, the fluid adjustment unit 500 is in the fluid cut-off state and the fluid medium is in the cut-off state. At this time, the oral care device 10 can be in the brushing mode or the shutdown state.

[0084] In some embodiments, the outer diameter of the lifting surface 4122 gradually increases from the side closer to the retaining surface 4121 to the side farther from the retaining surface 4121 (e.g., Figures 3 to 5 (as shown) or gradually decreases (not shown). That is, the lifting surface 4122 is a non-cylindrical surface, and the outer diameter of the lifting surface 4122 at different positions is set differently. In this embodiment, the amount of change in the outer diameter of the lifting surface 4122 is not further limited.

[0085] In this way, when the vector transmission rod 410 is swinging around its own axis and the switching element 520 is in contact with the lifting surface 4122, the fluid adjustment unit 500, or part of the fluid adjustment unit 500, will be offset relative to the vector transmission rod 410. The fluid adjustment unit 500 will be in a fluid communication state, and the fluid medium can be transported to the medium transport channel 411 through the fluid adjustment unit 500. At this time, the oral care device 10 can be in a mixed mode, and the user can perform brushing operation, or brushing and rinsing operation at the same time.

[0086] Furthermore, at this time, the greater the swing stroke of the vector transmission rod 410, the greater the extension and retraction offset of the fluid regulating unit 500 as a whole or part of the fluid regulating unit 500 relative to the vector transmission rod 410.

[0087] In other words, by setting a holding surface 4121 and a lifting surface 4122 on the outer wall of the drive section 412, and making the fluid regulating unit 500 abut against either the holding surface 4121 or the lifting surface 4122, the on / off state of the fluid medium can be changed, and the structure is relatively simple.

[0088] The lifting surface 4122 can be any curved surface, such as a parabolic cylinder or a hyperbolic cylinder. In some embodiments, the lifting surface 4122 is a plane, which has a simpler structure and is easier to process and shape.

[0089] Furthermore, the lifting surface 4122 and the holding surface 4121 are smoothly connected, that is, the lifting surface 4122 and the holding surface 4121 are smoothly connected. For example, the lifting surface 4122 and the holding surface 4121 have rounded corner cylindrical surfaces, or the lifting surface 4122 and the holding surface 4121 are tangent.

[0090] This avoids collisions and interference between the fluid regulating unit 500 and the drive section 412 when the fluid regulating unit 500 switches between the lifting surface 4122 and the holding surface 4121, thus preventing noise. The oral care device 10 switches more smoothly between different modes.

[0091] In some embodiments, the fluid regulating unit 500 includes a regulating body 510, which has a transition section 511. A transition space is constructed within the transition section 511, meaning that the transition section 511 is a hollow tubular structure.

[0092] The fluid regulating unit 500 also includes a cover 530 and a switching element 520. The cover 530 can be opened and closed to seal the first end of the transition space, and the sealing end of the switching element 520 is located at the second end of the transition space. That is to say, the sealing ends of the cover 530 and the switching element 520 can respectively seal the opposite ends of the transition section 511 and form a sealable cavity. For ease of explanation, this sealable cavity can be called a variable cavity.

[0093] In this embodiment, the first end of the transition space can be the end away from the vector transmission rod 410. This embodiment takes the two ends of the transition space as the end close to the vector transmission rod 410 as an example for explanation. In this way, the extension length of the switching member 520 is small and the structure of the fluid adjustment unit 500 is relatively simple.

[0094] The switching element 520 is configured to extend into or out of the transition space under the action of the vector transmission rod 410. That is, the switching element 520 extends or retracts relative to the transition section 511 under the pressure of the vector transmission rod 410, and the extension / retraction direction of the switching element 520 forms an angle with the main extension line 110, which can be an acute or obtuse angle. In some embodiments, the extension / retraction direction of the switching element 520 is perpendicular to the main extension line 110, facilitating assembly.

[0095] Therefore, during the process of the switching component 520 extending and retracting within the transition space and relative to the transition section 511, the volume of the variable cavity changes.

[0096] Understandably, when the switching element 520 moves away from the sealing element 530, the volume of the variable cavity increases, and the air pressure inside the variable cavity gradually decreases, i.e., it becomes a negative pressure state. The sealing element 530 can maintain the sealing of the first end of the transition space. Then, when the switching element 520 extends out of the transition space, the variable cavity is switched to an open state, that is, the second end of the transition space is connected to the medium supply unit 300. The fluid medium in the medium supply unit 300 can be transported into the transition space under the negative pressure attraction until the switching element 520 moves towards the sealing element 530 and seals the second end of the transition space. At this time, some fluid medium is temporarily stored in the sealed variable cavity.

[0097] In some embodiments, to facilitate the delivery of fluid media into the variable cavity, the transition space can be connected to the bottom wall of the media container via a pipeline, such as a feed pipe, so that the fluid media can flow into the variable cavity with the assistance of its own gravity.

[0098] In some embodiments, when the switching member 520 moves toward the side closer to the capping member 530, the volume of the variable cavity decreases, and the fluid pressure within the variable cavity gradually increases. Here, fluid pressure can refer to gas pressure or liquid pressure. Furthermore, the capping member 530 is configured to open the first end of the transition space under the fluid pressure when the sealing end of the switching member 520 is displaced toward the side closer to the capping member 530. That is, when the switching member 520 moves toward the side closer to the capping member 530 (e.g., by…), the fluid pressure increases. Figure 3 (During the process of drawing changes), the fluid pressure in the variable cavity gradually increases, the cover 530 is squeezed by the fluid and moves away from the transition section 511 until the cover 530 opens the first end of the transition space, the variable cavity is converted to the open state, that is, the first end of the transition space is connected to the medium conveying channel 411, and the fluid medium in the variable cavity can be conveyed to the medium conveying channel 411 under the squeezing of the switching member 520 until the cover 530 moves towards the transition section 511 and seals the first end of the transition space.

[0099] In other words, the fluid communication state of the fluid regulating unit 500 is the alternating opening and closing state of the cover 530 and the switching member 520. That is, under the drive of the vector transmission rod 410, the fluid medium in the medium supply unit 300 can be transported to the medium transport channel 411 by the alternating opening and closing of the cover 530 and the switching member 520. The structure is relatively simple and the power consumption is low.

[0100] Understandably, the volume of fluid medium delivered by the fluid regulating unit 500 in a single operation is related to the telescopic stroke of the switching element 520, i.e., the swing stroke of the vector transmission rod 410. In other words, by increasing the swing stroke of the vector transmission rod 410, the reciprocating stroke of the switching element 520 can be increased, thus increasing the volume of fluid medium delivered by the fluid regulating unit 500 in a single operation. Furthermore, when the reciprocating stroke of the switching element 520 is larger, the pressure change within the variable cavity is more significant, effectively driving the fluid medium flow, resulting in higher fluid medium delivery efficiency.

[0101] Alternatively, the conveying efficiency of the fluid regulating unit 500 can be changed by altering the oscillation frequency of the vector transmission rod 410, thereby increasing the number of oscillations of the vector transmission rod 410 per unit time, i.e., the number of reciprocating movements of the switching element 520.

[0102] In some embodiments, the cover 530 is configured as a self-recovering member whose shape can be restored, wherein self-recovery refers to its ability to recover its deformation, i.e., the self-recovering member is an elastic member. The cover 530 covers the end face (not shown) of the first end of the transition space. For example, the cover 530 is an approximately sheet-like or plate-like member, and the size of the cover 530 is larger than the size of the transition space. Its material is silicone or rubber, etc. The first end of the transition space is sealed by the mutual adhesion between the outer wall surface of the cover 530 and the end face of the transition space, and the sealing performance is good.

[0103] Furthermore, when the cover 530 separates from the end face of the first end of the transition space, the first end of the transition space can be opened, making the operation relatively convenient.

[0104] In some embodiments, the cover 530 may also extend into the transition space (e.g. Figures 3 to 5 As shown), at this time, the cover 530 can be a block, such as a rubber block or a silicone block. The circumferential sidewall of the cover 530 abuts against the inner wall of the first end of the transition space. That is, the size of the cover 530 in its natural state is larger than the size of the transition space. In this way, after the cover 530 is inserted into the transition space, the cover 530 is correspondingly squeezed and deformed to seal the first end of the transition space. It is also necessary to apply force to resist the friction between the cover 530 and the inner wall of the transition space in order to move the cover 530 relative to the transition space, resulting in good sealing performance.

[0105] In some embodiments, the switching member 520 includes a switching member body and a blocking part. The blocking part is connected to the end of the switching member body away from the vector transmission rod 410, that is, one end of the switching member body is used to abut against the vector transmission rod 410, and the other end is used to connect with the blocking part.

[0106] The sealing part is an elastic element, such as a rubber or silicone element. Similar to the cover 530, the sealing part can also cover the end face of the second end of the transition space or extend into the transition space; this will not be elaborated further in this embodiment.

[0107] In some embodiments, the sealing position of the capping member 530 and the sealing position of the sealing part can be arbitrarily set. For example, the capping member 530 covers the end face of the first end, and the sealing part extends into the transition space; or the capping member 530 and the sealing part extend into the first end and the second end of the transition space, respectively. This embodiment does not make further limitations.

[0108] In some embodiments, the fluid regulating unit 500 includes a first self-resetting member 531, which can be a spring, such as a coil spring, and correspondingly, the self-resetting force of the first self-resetting member 531 is an elastic force. The first self-resetting member 531 connects the cover member 530 and the regulating body 510, and the self-resetting force of the first self-resetting member 531 is directed towards one side of the transition space. In this way, the cover member 530 seals the first end of the transition space under the action of the self-resetting force of the first self-resetting member 531.

[0109] In other words, under normal conditions, the first end of the transition space is blocked by the capping member 530, meaning the fluid regulating unit 500 is in a fluid cut-off state. Thus, when the oral care device 10 is in a stopped state or in brushing mode, the fluid medium will not be discharged from the composite component 200.

[0110] In some embodiments, the fluid regulating unit 500 includes a second self-resetting member 521, which can be a spring, such as a coil spring. Accordingly, the self-resetting force of the second self-resetting member 521 is an elastic force. The second self-resetting member 521 connects the switching member 520 and the regulating body 510, and the self-resetting force of the second self-resetting member 521 is directed towards the vector transmission rod 410. In this way, the switching member 520 can press against the vector transmission rod 410 under the action of the self-resetting force of the first self-resetting member 531, so that the switching member 520 and the vector transmission rod 410 are kept in contact, and the switching member 520 and the vector transmission rod 410 are prevented from separating from each other.

[0111] In some embodiments, in order to connect the medium delivery channel 411 and the medium supply unit 300 through the fluid adjustment unit 500, the adjustment body 510 further includes a first guide section 512 and a second guide section 513. The first guide section 512 and the second guide section 513 are respectively disposed at opposite ends of the transition section 511. The inner cavities of the first guide section 512 and the second guide section 513 are both connected to the transition space, that is, the first guide section 512 and the second guide section 513 both have cavities for the flow of fluid medium.

[0112] The first guide section 512 and the second guide section 513 are located upstream and downstream of the fluid medium flow direction, respectively. Thus, the inner cavity of the first guide section 512 is connected to the medium supply unit 300, and the fluid medium can be transported from the medium supply unit 300 to the first guide section 512. The inner cavity of the second guide section 513 is connected to the medium transport channel 411, and the fluid medium discharged through the transition space can enter the inner cavity of the second guide section 513, so as to realize the fluid medium being transported to the medium transport channel 411 via the fluid regulating unit 500.

[0113] In some embodiments, in order to allow the fluid medium to flow between the first guide section 512 and the transition section 511 and between the transition section 511 and the second guide section 513, the inner diameter of the first guide section 512 and the inner diameter of the second guide section 513 are both larger than the inner diameter of the transition section 511. That is, a stepped surface is provided between the first guide section 512 and the transition section 511 and between the second guide section 513 and the transition section 511. This stepped surface can be referred to as the end face of the transition space.

[0114] Thus, when the sealing portion of the cover 530 opens the variable cavity, the fluid medium can be transported from the first guide section 512 to the transition section 511 via the circumferential sidewall of the cover 530. When the switching member 520 opens the variable cavity, the fluid medium can be transported from the transition section 511 to the second guide section 513 via the circumferential sidewall of the sealing portion.

[0115] In some embodiments, the switching member 520 passes through the side wall of the first guide section 512 and abuts against the vector transmission rod 410, and the switching member 520 is slidably connected to the side wall of the second guide section 513, so that the switching member 520 can extend and retract relative to the second guide section 513 under the drive of the drive section 412.

[0116] In some embodiments, the media delivery channel 411 extends axially through both ends of the vector transmission rod 410, meaning the vector transmission rod 410 is a hollow rod with an internally hollow interior. Thus, the end of the vector transmission rod 410 furthest from the composite member 200 is used for inputting the fluid medium. Correspondingly, the media supply unit 300 can be located at the end of the vector generation unit 400 furthest from the composite member 200 to reduce the circumferential dimensions of the oral care device 10 and make it easier for the user to grip.

[0117] The second guide section 513 can be connected to any position of the vector transmission rod 410, for example, an arc-shaped hole connected to the inner cavity of the second guide section 513 can be provided on the side wall of the vector transmission rod 410.

[0118] In some embodiments, the second guide section 513 may also be rotatably connected to the end of the vector transmission rod 410 away from the composite member 200. That is, the fluid regulating unit 500 and the composite member 200 are respectively disposed at opposite ends of the vector transmission rod 410. For example, the end of the vector transmission rod 410 away from the composite member 200 may extend into the second guide section 513 via the side wall of the second guide section 513, and the vector transmission rod 410 is rotatably connected to and sealed with the side wall of the second guide section 513. In this way, the fluid medium can be transported from one end of the vector transmission rod 410 to the other end via the medium transport channel 411.

[0119] In some embodiments, the oral care device 10 further includes a power module 610, a charging module 620, and a control panel 630. The power module 610 and the charging module 620 are sequentially and spaced apart at the end of the vector generation unit 400 away from the composite member 200, i.e., the power module 610 and the charging module 620 are sequentially positioned below the vector generation unit 400. Optionally, the power module 610 and the charging module 620 are arranged along the extension direction of the main extension line 110.

[0120] The control panel 630 has multiple control buttons, each controlling a different operating state of the integrated care device. For example, among the control buttons are a power switch and buttons for selecting different modes.

[0121] The control panel 630 is located near the second contoured grip surface 140 of the unbalanced housing 100. The second contoured grip surface 140 is provided with through holes for exposing the control buttons, so that when the control panel 630 is installed in the unbalanced housing 100, the control buttons can protrude from the through holes for easy operation by the user.

[0122] In some embodiments, a soft rubber pad integrally formed with the unbalanced housing 100 may be provided at the through hole, and the soft rubber pad covers the through hole to prevent foreign objects from entering the interior of the unbalanced housing 100 through the through hole.

[0123] In some embodiments, for ease of assembly, a combination bracket may be provided inside the unbalanced housing 100, and the vector generation unit 400, adjustment body 510, power module 610, etc., can be pre-installed on the combination bracket. This arrangement can improve the integration of the oral care device 10 and increase its assembly efficiency.
