Description

Technical Field

[0001] The present application relates to the technical field of oral cleaning, and in particular to an oral care device and a seal. Background Art

[0002] In the related art, the water flosser uses a knob to open and close the base station unit, and / or uses a knob to adjust the gear position to achieve different water flow impact effects. At the same time, in order to prevent external water vapor from damaging the electronic components inside the knob, an O-ring is usually provided between the knob and the main shell to block the water vapor.

[0003] However, during the long-term rotation of the knob, a single O-ring is prone to deformation and wear, which can lead to seal failure and affect the water vapor barrier. If multiple O-rings are used, the resistance to the relative rotation of the knob switch and the main housing will increase, so that the user needs to use greater force to turn the knob, affecting the user experience. Summary of the invention

[0004] The purpose of the present application is to provide an oral care device and a seal, which can achieve a sealing effect between the knob and the main shell while improving the rotational resistance of the knob and enhancing the user experience.

[0006] The technical solution provided by the present application is to set a first seal in the gap channel formed between the rotating adjustment component and the main shell, and use the first seal to block the communication between the built-in chamber and the external environment, thereby reducing the possibility that water vapor and / or liquid in the external environment enters the built-in chamber through the gap channel and damages the electronic devices in the built-in chamber. At the same time, the main shell has an annular blocking member, which is arranged around the rotating sensing component and extends upward into the gap channel. In this way, the annular blocking member can reduce the flow area of ​​the gap channel at the annular blocking member. When water vapor / liquid flows along the gap channel to the built-in chamber, the water vapor and / or liquid is at least partially blocked by the annular blocking member, thereby further reducing the possibility that water vapor and / or liquid in the external environment enters the built-in chamber through the gap channel and damages the electronic devices in the built-in chamber, thereby improving the service life of the oral care device.

[0026] In the relevant technical field, the oral cleaning device generally includes a base unit and an oral cleaner, wherein the base unit is used to provide water flow to the oral cleaner so as to achieve oral cleaning by water flow impact. A knob for rotation adjustment is generally provided on the main housing of the base unit, so that the base unit can be turned on and off by the knob, and / or different gears can be adjusted by the knob, so as to achieve a variety of water flow impact effects.

[0027] In order to protect the electronic components inside the knob (such as the control panel, display components, etc.) and the electronic components inside the base station unit connected to the knob from moisture, an O-ring is usually installed between the knob and the main housing to form a waterproof barrier. However, the O-ring may deform and wear during long-term rotation, which may lead to a decrease in sealing performance and affect its ability to block water vapor. If multiple O-rings are added to enhance the sealing effect, although the sealing can theoretically be improved, it will also increase the friction between the knob and the main housing in relative rotation. In this way, the user needs to apply more force when rotating the knob, which not only reduces the convenience of use, but also affects the user experience.

[0028] In order to solve this problem, the inventor of the present application sets an annular blocking member on the main shell, and the annular blocking member extends upward to the inside of the knob, so that the gap channel between the knob and the main shell forms an upward arched area. In this way, when water vapor flows into the inside of the knob through the gap channel between the knob and the main shell, the water vapor will hit the annular blocking member and be blocked by the annular blocking member, thereby reducing the water vapor that continues to penetrate into the gap channel and improving the blocking effect of water vapor. At the same time, it will not increase the rotational resistance between the knob and the main shell bracket, which is convenient for the user's rotation adjustment operation and improves the user experience. At the same time, the present application also replaces the existing O-ring with a sealing ring with a plurality of sealing lip structures, providing multiple seals, further improving the sealing effect, and the seal with multiple sealing lip structures has a small abutment force with the knob, further reducing the rotational resistance between the knob and the main shell bracket.

[0029] In addition, the knobs used in the device only have adjustment functions and lack the ability to display the current adjustment status in real time. This design limitation prevents users from directly seeing the specific position of the knob or the selected gear, making it difficult to intuitively understand the operating mode of the device. This lack of transparency may cause inconvenience to users because they need to rely on memory or try different settings to achieve the desired water impact effect, which will undoubtedly affect the intuitiveness and satisfaction of users in using the product.

[0030] To this end, the present application further integrates a display function in the knob, such as a digital display or indicator light, to intuitively show the user the current adjustment status. Such an improvement allows users to know at a glance the gear or setting they have selected, thereby more conveniently and accurately controlling the working state of the water flosser, enhancing the interaction between the user and the product, and improving user satisfaction.

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0032] The present application provides an oral care device, which may include a base station unit 1000. The base station unit 1000 may be used as a water supply module to provide liquid for rinsing to an oral cleaner 2000. At the same time, an adjustment structure may be provided on the base station unit 1000 to adjust the water flow impact effect provided by the base station unit 1000. Of course, the base station unit 1000 may also be used as a charging module, and the base station unit 1000 is used to charge the oral cleaner 2000. The oral cleaner 2000 is used to interact with the user's oral cavity and provide water flow impact and / or bristle movement to clean the user's oral cavity.

[0033] Please also see Figures 1 to 5 In a feasible implementation, the base station unit 1000 may include a main shell 100, which serves as the main body of the base station unit 1000. The main shell 100 may support and / or protect other components of the base station unit 1000 except the main shell 100. The main shell 100 may also provide support or loading and placement for the oral cleaner 2000.

[0034] In this embodiment, the base station unit 1000 may also include a knob structure 200. The knob structure 200 is used as an adjustment structure for opening and closing the liquid supply and / or adjusting the water flow impact effect. Specifically, the knob structure 200 may include a rotation sensing component 210 and a rotation adjustment component 220, and the rotation adjustment component 220 has a built-in chamber 221, and the built-in chamber 221 is used to at least partially accommodate the rotation sensing component 210. In other words, the rotation sensing component 210 is built into the built-in chamber 221 of the rotation adjustment component 220, so as to avoid direct exposure of the rotation sensing component 210, and effectively reduce the possibility of damage to the rotation sensing component 210. The rotation sensing component 210 has a first part 211 and a second part 212 that can rotate relative to each other, and the first part 211 is connected to the main housing 100 so that it can be fixed relative to the main housing 100. The second part 212 is connected to the rotating adjustment component 220. When the rotating adjustment component 220 rotates, the rotating adjustment component 220 drives the second part 212 to rotate relative to the first part 211, so that the rotating sensing component 210 can detect the rotation angle of the rotating adjustment component 220 according to the relative rotation angle of the second part 212 relative to the first part 211, thereby controlling the liquid supply opening and closing and / or the water flow impact effect.

[0035] In practical applications, the base unit 1000 may also include a liquid storage unit for storing liquid, a power assembly for transporting liquid from the liquid storage unit to the oral cleaner 2000, and a control panel for controlling the power assembly. The rotation sensing component 210 and the power assembly are electrically connected to the control panel respectively, and the power assembly is used to provide power for extracting liquid from the liquid storage unit and discharging the liquid to the oral cleaner 2000. The rotation sensing component 210 is used to detect the rotation information (such as angle, speed, etc.) of the user's operation of the rotation adjustment component 220 and convert the rotation information into an electrical signal and feed it back to the control panel, and the control panel controls the start and stop of the power assembly and / or the amount of water discharged based on the electrical signal. Among them, the rotation sensing component 210 can use a rotary encoder, and the power assembly can use a water pump.

[0036] Since the rotation adjustment component 220 is connected to the main housing 100 through the rotation sensing component 210, there is an assembly gap between the rotation adjustment component 220 and the main housing 100. Accordingly, a gap channel is formed between the rotation adjustment component 220 and the main housing 100 to connect the built-in chamber 221 and the external environment, that is, water vapor and / or liquid in the external environment can enter the built-in chamber 221 through the gap channel, thereby posing a risk of damage to the electronic devices (such as the rotation sensing component 210, the display component, etc.) located in the built-in chamber 221. To this end, the base station unit 1000 may also include a first sealing member 300, which is disposed in the gap channel, thereby blocking the built-in chamber 221 from communicating with the external environment, and reducing the possibility that water vapor and / or liquid in the external environment enter the built-in chamber 221 through the gap channel to damage the electronic devices in the built-in chamber 221. At the same time, the main shell 100 has an annular blocking member 110, which is arranged around the rotating sensing component 210 and extends upward into the gap channel. In this way, the annular blocking member 110 can reduce the flow area of ​​the gap channel at the annular blocking member 110. When water vapor / liquid flows along the gap channel to the built-in chamber 221, the water vapor and / or liquid is at least partially blocked by the annular blocking member 110, thereby further reducing the possibility of water vapor and / or liquid in the external environment entering the built-in chamber 221 through the gap channel and damaging the electronic devices in the built-in chamber 221, thereby improving the service life of the oral care device.

[0037] In practical applications, the knob structure 200 can be installed on the top of the main housing 100, and the axes of the knob structure 200 and the annular blocking member 110 are perpendicular to the horizontal plane, so as to facilitate the user's adjustment operation. The knob structure 200 can also be installed on the side of the main housing 100, but the axes of the knob structure 200 and the annular blocking member 110 should also be substantially perpendicular to the horizontal plane to avoid affecting the blocking effect of the annular blocking member 110 on water vapor and / or liquid.

[0038] The control board can be installed in the chamber surrounded by the main housing 100. Accordingly, the main housing 100 can be provided with a clearance hole that connects the built-in chamber 221 with the chamber surrounded by the main housing 100, so that the wiring harness connecting the control board with the electronic components in the built-in chamber 221 can pass through the clearance hole through the main housing 100. In this way, it can be understood that the first sealing member 300 and the annular blocking member 110 can also prevent water vapor in the external environment from entering the main housing 100, thereby reducing the risk of damage to the electronic components in the main housing 100.

[0039] like Figure 3 and Figure 4As shown, in an achievable embodiment, the bottom surface of the rotation adjustment component 220 is provided with a first groove 222 which is annular and inwardly recessed, and the annular blocking member 110 extends into the first groove 222. In this way, the annular blocking member 110 can not only reduce the flow area of ​​the gap channel at the annular blocking member 110, but also change the path of the gap channel, that is, change the flow path of water vapor and / or liquid in the external environment to the built-in chamber 221 (such as Figure 4 The height of the annular barrier 110 is further increased, which increases the difficulty of liquid entering the built-in chamber 221 and improves the blocking effect on the liquid.

[0040] Along the gap channel direction, such as Figure 3 As shown, the first sealing member 300 may be located between the annular blocking member 110 and the built-in chamber 221. That is, when water vapor and / or liquid from the external environment moves toward the built-in chamber 221 through the gap channel, the water vapor and / or liquid first passes through the annular blocking member 110 and then passes through the first sealing member 300.

[0041] Of course, along the gap channel direction, the annular blocking member 110 may also be located between the first sealing member 300 and the built-in chamber 221. That is, when water vapor and / or liquid in the external environment moves toward the built-in chamber 221 through the gap channel, the water vapor and / or liquid will first pass through the first sealing member 300 and then through the annular blocking member 110.

[0042] However, considering that water vapor and / or liquid in the external environment moves to the built-in chamber 221 through the first seal 300 in sequence, when the water vapor and / or liquid passes through the first seal 300, the water vapor and / or liquid will be sealed by the first seal 300 between the first seal 300 and the built-in chamber 221, thereby evaporating into the built-in chamber 221, which makes the blocking effect of the annular blocking member 110 very small. Therefore, the present application preferably adopts the first seal 300 to be located between the annular blocking member 110 and the built-in chamber 221.

[0043] Regarding the specific structure of the first sealing member 300 , the present application provides three achievable embodiments for reference.

[0044] Embodiment 1: The first sealing member 300 may be an O-ring. In practical applications, the main housing 100 or the rotation adjustment component 220 forms an annular sealing ring receiving groove, the O-ring is pre-installed in the sealing ring receiving groove, and when the rotation adjustment component 220 is connected to the main housing 100, the O-ring abuts between the rotation adjustment component 220 and the main housing 100.

[0045] Embodiment 2: The first sealing member 300 may be a Y-shaped ring or a K-shaped ring. The Y-shaped ring or the K-shaped ring is installed on the main housing 100 , and two sealing lips of the Y-shaped ring or the K-shaped ring abut against the rotation adjustment component 220 .

[0046] Embodiment 3: Figure 3 and Figure 6 As shown, the first seal 300 has a mounting ring portion 310 and a sealing ring portion 320. The sealing ring portion 320 has at least two sealing lips 321, and the at least two sealing lips 321 are in contact with the rotation adjustment component 220 or the main housing 100, and the contact positions of the at least two sealing lips 321 with the rotation adjustment component 220 or the main housing 100 are arranged at intervals along the axis of the first seal 300.

[0047] Among them, when at least two sealing lips 321 are in contact with the main housing 100, the mounting ring portion 310 can be arranged on the rotation adjustment component 220, and the inner wall surface of the mounting ring portion 310 is provided with at least two annular protrusions 311, and the at least two annular protrusions 311 are arranged at intervals along the axial direction of the mounting ring portion 310 and are in contact with the rotation adjustment component 220, thereby forming multiple seals on the gap between the first sealing member 300 and the rotation adjustment component 220. The sealing ring portion 320 is located on the outer wall surface of the mounting ring portion 310, so that at least two sealing lips 321 can form multiple seals on the gap between the first sealing member 300 and the main housing 100. In this way, multi-layer sealing can be achieved for the gap channel through one first sealing member 300, thereby improving the sealing effect.

[0048] When at least two sealing lips 321 are in contact with the rotation adjustment component 220, the mounting ring portion 310 can be provided on the main housing 100, and the outer wall surface of the mounting ring portion 310 is provided with at least two annular protrusions 311, and the at least two annular protrusions 311 are arranged at intervals along the axial direction of the mounting ring portion 310 and are in contact with the main housing 100, thereby forming multiple seals on the gap between the first sealing member 300 and the main housing 100. The sealing ring portion 320 is located on the inner wall surface of the mounting ring portion 310, so that at least two sealing lips 321 can form multiple seals on the gap between the first sealing member 300 and the rotation adjustment component 220. In this way, multi-layer sealing can be achieved for the gap channel through one first sealing member 300, thereby improving the sealing effect.

[0049] Furthermore, it is worth mentioning that, compared with the O-ring solution, the first seal 300 in this embodiment is in contact and sealed with the rotation adjustment component 220 through at least two sealing lips 321. The contact area between the sealing lips 321 and the rotation adjustment component 220 is small, and no large abutment force is required, thereby reducing the friction between the first seal 300 and the rotation adjustment component 220, and reducing the rotational resistance of the relative rotation of the rotation adjustment component 220 and the main shell 100, making it convenient for users to operate the rotation of the rotation adjustment component 220, thereby improving the user's experience.

[0050] In practical applications, the annular protrusion 311 and the sealing lip 321 may each have two, or may be any one of two, three or four. When the annular protrusion 311 and the sealing lip 321 each have two and are used in conjunction with the annular blocking member 110, a good waterproof effect is achieved.

[0051] like Figure 3 and Figure 6 As shown, in an achievable embodiment, the bottom surface of the mounting ring portion 310 is provided with an annular second groove 312. Accordingly, the main housing 100 has an annular support 112 extending upward, and the mounting ring portion 310 is arranged on the main housing 100 by inserting the annular support 112 into the second groove 312. In this way, the connection method between the first seal 300 and the main housing 100 can be simplified, and the annular support 112 can also serve as a supporting structure of the first seal 300 to maintain the shape of the first seal 300 during the sealing process, and the annular support 112 can also serve as a limiting structure of the first seal 300 to limit the radial degree of freedom of the first seal 300, so as to avoid the annular support 112 from being offset in the radial direction, thereby ensuring the sealing effect between the annular protrusion 311 and the main housing 100, and the sealing effect between the sealing lip 321 and the rotating adjustment component 220.

[0052] Furthermore, in order to limit the degree of freedom of the first sealing member 300 in the axial direction, as Figure 3 As shown, in a feasible embodiment, the base station unit 1000 also includes a ring-shaped pressure plate 500, which is arranged on the main shell 100 and is located between the mounting ring portion 310 and the rotation adjustment component 220, so that the freedom of the first sealing member 300 in the axial direction can be limited by the cooperation between the pressure plate 500 and the main shell 100.

[0053] In practical applications, the outer diameter of the pressing plate 500 is substantially the same as the inner diameter of the annular blocking member 110, and the pressing plate 500 is installed in the area surrounded by the annular blocking member 110, so that the radial freedom of the pressing plate 500 is limited by the annular blocking member 110. The pressing plate 500 can be placed only on the main housing 100, or the pressing plate 500 can be connected to the main housing 100 by interference, bonding, or threading.

[0054] like Figure 3 and Figure 7As shown, in an achievable embodiment, the knob structure 200 may also be integrated with a display function, so as to display in real time the gear and mode adjusted by the rotation adjustment component 220. Specifically, the knob structure 200 may also include a display component 230, and the display component 230 may be located in the built-in chamber 221. In this way, users can know at a glance the gear or setting they have selected, so as to control the working state of the water flosser more conveniently and accurately, enhance the interaction between the user and the product, and improve the user satisfaction. In addition, the display component 230 may be located in the built-in chamber 221, and under the sealing effect of the above-mentioned first sealing member 300 and the annular blocking member 110, the possibility of external water vapor and / or liquid causing harm to the display component 230 can be effectively reduced.

[0055] In practical applications, the display component 230 can be a liquid crystal display device composed of a light shielding film, a light shielding cover and a display PCB board, which ensures clear display of images and stable operation of the device. The display component 230 can be electrically connected to the control board. When the control board receives the electrical signal of the rotation adjustment component 220, the control board transmits display information to the display component 230 based on the electrical signal, so that the display component 230 displays it.

[0056] The display component 230 can rotate along with the rotation adjustment component 220. In practical applications, the display component 230 can be connected to the rotation adjustment component 220 and / or the second portion 212 of the rotation sensing component 210, so as to rotate along with the rotation of the rotation adjustment component 220.

[0057] The display component 230 may also be stationary relative to the rotation adjustment component 220. In practical applications, the display component 230 may be connected to the first portion 211 of the rotation sensing component 210, or the display component 230 may be connected to a structure of the main housing 100 extending into the built-in chamber 221.

[0058] Considering that when the display component 230 rotates with the rotation adjustment component 220, the wiring harness connecting the display component 230 and the control panel will rotate together, which is prone to fatigue damage during long-term rotation, and the display direction of the display component 230 will change after the rotation, affecting the user's viewing. For this reason, the present application preferably adopts that the display component 230 is stationary relative to the rotation adjustment component 220, and the subsequent description is also based on this.

[0059] like Figure 3 and Figure 7As shown, in an achievable embodiment, the rotation adjustment component 220 may include a bottom shell 223 and an outer shell 224, wherein the bottom shell 223 and the outer shell 224 are connected, and the bottom shell 223 and the outer shell 224 surround and form a first chamber 2211, and the first chamber 2211 is at least a part of the built-in chamber 221. The display component 230 is installed in the first chamber 2211, and a second sealing member 400 is provided at the connection between the bottom shell 223 and the outer shell 224, so as to prevent external water vapor and / or liquid from entering the built-in chamber 221 through the connection between the bottom shell 223 and the outer shell 224, thereby ensuring the sealing effect.

[0060] In practical applications, the bottom shell member 223 may be at least partially inserted into the outer shell member 224 , or the outer shell member 224 may be at least partially inserted into the bottom shell member 223 , or the bottom shell member 223 may abut against the outer shell member 224 .
