Description

Technical Field

[0001] This disclosure relates to the technical field of cleaning appliances, and particularly to an oral cleaning device, an oral cleaner, and a gripping component. Background Technology

[0002] To facilitate the cleaning of residual limescale, bacteria, or impurities inside the water tank of a water flosser, a removable bottom cover is usually inserted at the bottom of the water flosser, allowing users to easily open the bottom cover for thorough cleaning.

[0003] Meanwhile, to ensure a tight seal between the bottom cover and the inner wall of the water tank and prevent leakage, a sealing ring is usually installed between the bottom cover and the inner wall of the water tank, and the interference fit between the sealing ring and the inner wall of the water tank is appropriately increased. However, while this design effectively improves the sealing effect, it also requires users to apply considerable force when installing or removing the bottom cover, affecting the convenience and comfort of use. Utility Model Content

[0004] The purpose of this disclosure is to provide an oral cleaning device, an oral cleaner, and a gripping component that can facilitate the disassembly and assembly of the sealing component while ensuring a sealing effect, thereby improving the user experience.

[0005] According to one aspect of this disclosure, an oral cleaning device is provided, the oral cleaning device including a gripping component and a pump mechanism, wherein the gripping component includes:

[0006] The main body has a central axis, a accommodating cavity for accommodating the pump mechanism, and a liquid storage cavity with an opening. The liquid inlet end of the pump mechanism is connected to the liquid storage cavity. The liquid storage cavity has a first inner wall surface and a second inner wall surface. The first inner wall surface is located between the second inner wall surface and the opening. The second inner wall surface is arranged closer to the central axis than the first inner wall surface.

[0007] A sealing member has an insertion part, on which a sealing element is sleeved. The sealing member is at least partially inserted into the liquid storage cavity through the insertion part and the opening. The sealing element is interference-fitted with the second inner wall surface.

[0008] The solution provided in this disclosure divides the inner wall surface of the liquid storage cavity near the opening into a first inner wall surface and a second inner wall surface, with the first inner wall surface located between the second inner wall surface and the opening. Simultaneously, the second inner wall surface is positioned closer to the central axis than the first inner wall surface; that is, the cross-sectional area of ​​the second inner wall surface is smaller than that of the first inner wall surface. Thus, during the insertion of the sealing element into the liquid storage cavity through the opening, the sealing element passes sequentially through the first and second inner wall surfaces. This ensures that the interference fit between the sealing element and the first inner wall surface is less than that between the sealing element and the second inner wall surface. Consequently, less force is required for insertion and removal of the sealing element as it passes through the first inner wall surface, reducing the force applied during the entire assembly and disassembly process. In this way, by maintaining the interference fit between the second inner wall surface and the sealing element, the sealing effect is guaranteed, while by changing only the interference fit between the first inner wall surface and the sealing element, only a smaller force is needed to assemble and disassemble the sealing component, improving the user experience.

[0009] Furthermore, the second inner wall surface is arranged closer to the central axis than the first inner wall surface. Consequently, the opening area of ​​the opening formed by the end of the first inner wall surface is larger, which allows the sealing element with sealing elements to be easily inserted into the opening without alignment, facilitating the installation of the sealing element.

[0010] According to another aspect of this disclosure, an oral cleaner is also provided, the oral cleaner comprising a care element and the oral cleaning device described above, the care element having a cavity and an outlet communicating with the cavity, the outlet end of the pump mechanism communicating with the cavity.

[0011] According to another aspect of this disclosure, a gripping component is also provided, the gripping component comprising:

[0012] The main body has a central axis, a accommodating cavity, and a liquid storage cavity with an opening. The liquid storage cavity has a first inner wall surface and a second inner wall surface. The first inner wall surface is located between the second inner wall surface and the opening. The second inner wall surface is arranged closer to the central axis than the first inner wall surface.

[0013] A sealing member has an insertion part, on which a sealing element is sleeved. The sealing member is at least partially inserted into the liquid storage cavity through the insertion part and the opening. The sealing element is interference-fitted with the second inner wall surface.

[0014] According to another aspect of this disclosure, an oral cleaning device is also provided, the oral cleaning device including a gripping component and a pump mechanism, wherein the gripping component includes:

[0015] The main body has a central axis, a accommodating cavity for accommodating the pump mechanism, and a liquid storage cavity with an opening. The liquid inlet end of the pump mechanism is connected to the liquid storage cavity. The liquid storage cavity has a first inner wall surface, which moves inward from the opening toward the inside of the liquid storage cavity.

[0016] The sealing member has an insertion part, on which a sealing element is sleeved. The sealing member is at least partially inserted into the liquid storage cavity through the insertion part and the opening. The sealing element is interference-fitted with the first inner wall surface. Attached Figure Description

[0035] A water flosser uses a pump to deliver a high-pressure jet of water, which is then used to clean teeth and between teeth. Water flossers can have an integrated water tank for easy portability. They can also be used with a cleaning station, where the station's internal water tank provides the rinsing water flow. In water flossers with an integrated water tank, scale, bacteria, or impurities can easily accumulate in the tank after prolonged use (especially with tap water). To facilitate cleaning, a removable bottom cover is usually designed at the bottom of the water flosser, allowing users to easily open the cover for thorough cleaning of the tank's inner surface.

[0036] Considering that liquid inside the water tank can leak out through the gap between the bottom cover and the inner wall of the tank, a sealing ring is usually installed between the bottom cover and the inner wall of the tank. The interference fit between the sealing ring and the inner wall is also appropriately increased to ensure a tight seal and prevent leakage. However, while this design effectively improves the sealing effect, it also requires users to apply considerable force when installing or removing the bottom cover, affecting the convenience and comfort of use.

[0037] To address this, this disclosure attempted to reduce the interference fit between the sealing ring and the inner wall of the water tank to facilitate the disassembly and assembly of the bottom cover. However, this approach resulted in a reduced sealing effect and leakage.

[0038] Based on this, this disclosure improves the inner wall surface of the water tank. Specifically, by dividing the bottom of the inner wall surface of the water tank into a first inner wall surface and a second inner wall surface from bottom to top, and by placing the second inner wall surface closer to the inside, the interference fit between the sealing element and the first inner wall surface is less than the interference fit between the sealing element and the second inner wall surface when the bottom cover with the sealing element is inserted into the water tank. This ensures a good seal without changing the interference fit between the sealing element and the second inner wall surface. Furthermore, the bottom cover can be inserted or removed with less force when the sealing element passes through the first inner wall surface. This also increases the area of ​​the bottom opening of the water tank, making it easier to insert the bottom cover with the sealing element, thus facilitating the installation and removal of the bottom cover and improving the user experience. On the other hand, the sealing element is improved. Specifically, the sealing element is constructed as an integral base and sealing part, with the base fitted onto the bottom cover and the sealing part inclined outward from the base in the opposite direction to the insertion direction of the bottom cover. In this way, as the sealing element initially enters the second inner wall surface, the interference fit between the sealing part and the second inner wall surface gradually increases, which can also reduce the force applied by the user, making it easier to insert the bottom cover. It can also reduce the cross-sectional area of ​​the insertion end of the sealing element, making it easier to insert the bottom cover with the sealing element, thereby facilitating the installation and removal of the bottom cover and further improving the user experience.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this disclosure, but not all embodiments.

[0040] like Figure 1 As shown, this disclosure provides an oral hygiene device. The oral hygiene device may include an oral hygiene apparatus 1000 and a care element 2000. The oral hygiene apparatus 1000 may be configured in a shape suitable for holding, so that a user can operate the oral hygiene device to perform a cleaning operation by holding the oral hygiene apparatus 1000. The oral hygiene apparatus 1000 may provide a water flow to at least the care element 2000 to perform a water jet impact through the care element 2000, thereby rinsing and cleaning the oral cavity.

[0041] Regarding the specific structure of the oral cleaning device 1000, as follows: Figures 2 to 5As shown, in some embodiments, the oral cleaning device 1000 may include a gripping component 100 and a pump mechanism 200. The gripping component 100 may include a main body 110, which serves as the primary supporting housing structure of the oral cleaning device 1000. It not only supports and protects other components of the oral cleaning device 1000 but can also be configured in a shape suitable for gripping to facilitate operation. Specifically, the main body 110 may have a central axis 111, a receiving cavity 112, and a liquid storage cavity 113. The receiving cavity 112 and the liquid storage cavity 113 are isolated from each other, forming a dry-wet separation design to prevent liquid in the liquid storage cavity 113 from seeping into the receiving cavity 112 and damaging the electronic components within the receiving cavity 112. The pump mechanism 200 may be located within the receiving cavity 112, and the inlet end of the pump mechanism 200 is connected to the liquid storage cavity 113 to draw liquid from the liquid storage cavity 113. The liquid storage cavity 113 has an opening 1131, through which the interior of the liquid storage cavity 113 can be cleaned or liquid can be introduced into the liquid storage cavity 113. For example, the opening 1131 may be located as follows: Figure 2 From a certain perspective, the bottom surface of the main body 110 has its central axis 111 passing through the opening 1131; of course, the opening 1131 can also be located on the side or top surface of the main body 110. Considering that the bottom surface of the main body 110 can have a large opening area and can clean the inner wall of the liquid storage cavity 113 along a straight direction, it is preferable that the opening 1131 is located on the bottom surface of the main body 110. The liquid storage cavity 113 also has a first inner wall surface 1132 and a second inner wall surface 1133. Both the first inner wall surface 1132 and the second inner wall surface 1133 are annular walls. The first inner wall surface 1132 is located between the opening 1131 and the second inner wall surface 1133, and the second inner wall surface 1133 is arranged closer to the central axis 111 than the first inner wall surface 1132, or in other words, the second inner wall surface 1133 is arranged closer to the interior of the main body 110 than the first inner wall surface 1132. Taking a scenario where both the first inner wall surface 1132 and the second inner wall surface 1133 have circular cross-sections, the diameter of the first inner wall surface 1132 is larger than the diameter of the second inner wall surface 1133. Alternatively, taking a scenario where both the first inner wall surface 1132 and the second inner wall surface 1133 have elliptical cross-sections, the major and minor axes of the first inner wall surface 1132 are both larger than the major and minor axes of the second inner wall surface 1133. It should be noted that the central axis 111 can be the line connecting the centers of all cross-sections of the main body 110. The pump mechanism 200 can be used to extract and pressurize the liquid in the storage chamber 113 and eject it in the form of a pulsed water flow; its specific structure can be found in existing technology.

[0042] The gripping component 100 may further include a sealing member 120, which is used to seal the opening 1131 to prevent liquid in the liquid storage cavity 113 from leaking out through the opening 1131. Specifically, the sealing member 120 may have an insertion portion 121, on which a sealing element 130 is sleeved. The sealing member 120 is at least partially inserted into the liquid storage cavity 113 through the insertion portion 121 and the opening 1131, and the sealing element 130 is interference-fitted with the second inner wall surface 1133.

[0043] For example, during the process of the sealing element 120 being at least partially inserted into the liquid storage cavity 113 through the insertion part 121 and the opening 1131, the sealing element 130 may not contact the first inner wall surface 1132, that is, the interference between the sealing element 130 and the first inner wall surface 1132 is 0; of course, the sealing element 130 may also contact the first inner wall surface 1132.

[0044] It is worth mentioning that this disclosure divides the inner wall surface of the liquid storage cavity 113 near the opening 1131 into a first inner wall surface 1132 and a second inner wall surface 1133, and positions the first inner wall surface 1132 between the second inner wall surface 1133 and the opening 1131. Simultaneously, the second inner wall surface 1133 is arranged closer to the central axis 111 than the first inner wall surface 1132; that is, the cross-sectional area of ​​the second inner wall surface 1133 is smaller than that of the first inner wall surface 1132. Thus, when the liquid storage cavity is fitted with… During the insertion of the sealing element 130's insertion portion 121 into the liquid storage cavity 113 through the opening 1131, the sealing element 130 sequentially passes through the first inner wall surface 1132 and the second inner wall surface 1133. This allows the interference fit between the sealing element 130 and the first inner wall surface 1132 to be smaller than the interference fit between the sealing element 130 and the second inner wall surface 1133. Therefore, less force is needed for insertion and removal as the sealing element 130 passes through the first inner wall surface 1132, reducing the force required during the entire assembly and disassembly process. In this way, by maintaining the interference fit between the second inner wall surface 1133 and the sealing element 130, the sealing effect is guaranteed. Furthermore, by changing only the interference fit between the first inner wall surface 1132 and the sealing element 130, only a smaller force is required to assemble and disassemble the sealing component 120, improving the user experience.

[0045] Furthermore, the second inner wall surface 1133 is arranged closer to the central axis 111 than the first inner wall surface 1132. Correspondingly, the opening area of ​​the opening 1131 formed by the end of the first inner wall surface 1132 is larger, so that the sealing element 120 with sealing element 130 can be easily inserted into the opening 1131, which facilitates the installation of the sealing element 120.

[0046] In practical applications, the sealing element 120 can be mounted on the main body 110 using the frictional force between it and the inner wall surface of the liquid storage cavity 113. To prevent the sealing element 120 from accidentally falling off, it can also be equipped with a snap-fit ​​structure. Corresponding slots are provided on the first inner wall surface 1132 and the second inner wall surface 1133. The snap-fit ​​structure and the slots cooperate to prevent the sealing element 120 from accidentally falling off. It is precisely because of the existence of the snap-fit ​​structure that the insertion part 121 needs to be long enough to have enough space to install the snap-fit ​​structure. Correspondingly, the sealing element 130 should be located at the end of the snap-fit ​​structure away from the opening 1131, so that there is a certain distance between the sealing element 130 and the opening 131.

[0047] Regarding the specific implementation of the arrangement of the second inner wall surface 1133 closer to the central axis 111 than the first inner wall surface 1132, this disclosure provides two feasible embodiments for reference.

[0048] Example 1, such as Figure 2 and Figure 3 As shown, the first inner wall surface 1132 is inclined from the second inner wall surface 1133 in a direction away from the central axis 111, or in other words, in Figure 3 From the view shown, the first inner wall surface 1132 is inclined to the lower left from the second inner wall surface 1133. This reduces the interference fit between the sealing element 130 and the first inner wall surface 1132.

[0049] In this embodiment, the second inner wall surface 1133 may have a preset angle β with the central axis 111, the preset angle β being in the range of [0, 5°]. One end of the first inner wall surface 1132 is connected to the second inner wall surface 1133, and the other end of the first inner wall surface 1132 forms the aforementioned opening 1131, thereby facilitating processing operations.

[0050] Example 2, as follows Figure 5 As shown, the first inner wall surface 1132 and the second inner wall surface 1133 form a stepped surface structure.

[0051] In this embodiment, the first inner wall surface 1132, the second inner wall surface 1133, and the central axis 111 can be parallel to each other, thereby facilitating processing operations. The second inner wall surface 1133 and the central axis 111 can also be at a preset angle β.

[0052] In some embodiments, the sealing element 130 may be a sealing ring or a lip seal, etc.

[0053] In some other embodiments, such as Figures 6 to 9As shown, the sealing element 130 may include a base 131 and a sealing portion 132, wherein the base 131 is sleeved on the insertion portion 121, and the sealing portion 132 extends from the base 131 in a radially outward direction perpendicular to the central axis 111, thereby forming a seal by the sealing portion 132 pressing against the second inner wall surface 1133.

[0054] For example, the base 131 can be configured as an annular ring structure to increase the connection friction between the base 131 and the insertion part 121. The base 131 and the sealing part 132 can be an integral structure, and the base 131 and the sealing part 132 can be made of materials with certain elastic properties such as rubber and silicone.

[0055] Furthermore, the sealing portion 132 extends from the base 131 in a radially outward direction perpendicular to the central axis 111 while also extending away from the pump mechanism 200, or in other words, in such a direction... Figure 6 From the shown perspective, the sealing portion 132 is inclined outward and downward from the base 131, and there is a preset included angle α between the sealing portion 132 and the base 131. In this way, during the process of the sealing element 130 being inserted into the second inner wall surface 1133, the interference fit between the sealing portion 132 and the second inner wall surface 1133 gradually increases. This can also reduce the force applied by the user, facilitate the installation and removal of the sealing member 120 with the sealing element 130, and make the insertion of the sealing member 120 with the sealing element 130 smoother, further improving the user experience.

[0056] Furthermore, the preset included angle α is in the range of [15°, 65°], so that the sealing part 132 has a certain pressing effect on the second inner wall surface 1133, and at the same time, it can produce a certain deformation to increase the contact area, thereby improving the sealing effect. Preferably, the preset included angle α is in the range of [40°, 45°].

[0057] Furthermore, an annular groove 1211 may be provided on the outer wall surface of the insertion part 121, the base 131 is located in the annular groove 1211, and the sealing part 132 extends at least partially from the annular groove 1211. In this way, the annular groove 1211 can be used to restrict the movement of the base 131 along the central axis 111, ensuring the accuracy of the installation position of the sealing element 130 and guaranteeing the sealing effect.

[0058] In some embodiments, such as Figure 8As shown, one end of the sealing part 132 connected to the base 131 is defined as the fixed end, and the other end is the free end. The fixed end is connected to the end of the base 131 adjacent to the pump mechanism 200, and the free end extends beyond the middle position of the base 131 along the central axis 111. This allows for a longer sealing part 132, resulting in a smoother change in the interference fit between the sealing part 132 and the second inner wall surface 1133 during the insertion of the sealing element 130 into the second inner wall surface 1133. This means the force required from the user is also smoother, thus improving the user experience.

[0059] In some other embodiments, such as Figure 9 As shown, the fixed end can also be connected to the middle part of the base 131.

[0060] Regarding the specific structure of the sealing element 120, in some embodiments, the sealing element 120 may only have an insertion portion 121. When the sealing element 130 is in an interference fit with the second inner wall surface 1133, the insertion portion 121 may extend at least partially from the opening 1131, so that during disassembly, the insertion portion 121 can be grasped and disassembled by the portion of the insertion portion 121 extending out of the opening 1131. Of course, when the sealing element 130 is in an interference fit with the second inner wall surface 1133, the insertion portion 121 may not extend from the opening 1131, and the bottom of the insertion portion 121 may also be provided with an operable disassembly portion to disassemble the insertion portion 121, for example, the disassembly portion may be a threaded hole, a gripping groove, etc.

[0061] In some other embodiments, such as Figure 5 and Figure 6 As shown, the sealing member 120 may also have a shoulder 122, which is located at the end of the insertion portion 121 away from the sealing element 130, and the shoulder 122 protrudes relative to the outer wall surface of the insertion portion 121, and abuts against the end of the main body 110. Thus, when the sealing member 120 is inserted into the liquid storage cavity 113, the shoulder 122 abuts against the end of the main body 110 to indicate that the sealing member 120 is in place. At the same time, leaving the shoulder 122 outside the opening 1131 allows the sealing member 120 to be easily pulled out of the liquid storage cavity 113 by grasping the shoulder 122 when removing it.

[0062] For example, the sealing element 120 can be generally constructed as a barrel-shaped structure, and the sealing element 120 surrounds a liquid storage tank that communicates with the liquid storage cavity 113, thereby increasing the liquid storage capacity of the oral cleaning device 1000 and increasing the cleaning time of the oral cleaner. The outer wall surface of the shoulder 122 is in contact with the outer wall surface of the main body 110, thereby ensuring the integrity of the outer surface of the sealing element 120 and the main body 110, reducing the step difference of the outer surface of the oral cleaning device 1000, and improving the overall aesthetics. The sealing element 130 is disposed near the end of the insertion portion 121 away from the shoulder 122, and the cross-section of the insertion portion 121 decreases from the shoulder 122 toward the main body 110, thereby reducing the head size of the insertion portion 121, making it easier for the insertion portion 121 to be inserted into the opening 1131.

[0063] The inlet end of the pump mechanism 200 can be directly connected to the liquid storage chamber 113.

[0064] The inlet end of the aforementioned pump mechanism 200 can also be connected to the liquid storage chamber 113 via the extraction pipe 300. Specifically, as shown... Figure 2 As shown, in some embodiments, the oral cleaning device 1000 may further include a extraction tube 300, one end of which is located within the liquid storage chamber 113 and connected to a connector 310, and the other end of which is connected to the liquid inlet of the pump mechanism 200. Thus, after the sealing member 120 is removed, it can be directly connected to an external water source or a base station with a water tank via the connector 310, enabling flexible switching between integrated and external water source modes to meet different usage needs.

[0065] For example, in Figure 2 From the perspective shown, one end of the extraction tube 300 can extend as far as possible to the bottom of the liquid storage cavity 113, thereby allowing liquid to be extracted from the bottom of the liquid storage cavity 113 through the extraction tube 300. It should be noted that a certain gap should be maintained between the extraction tube 300 and the inner bottom surface of the liquid storage cavity 113 so that liquid in the liquid storage cavity 113 can enter the extraction tube 300 through this gap.

[0066] In some embodiments, such as Figure 1 As shown, the oral irrigator described above can be configured as a water flosser to clean teeth and interdental spaces using the impact force of a high-speed water jet. Accordingly, the care element 2000 can be constructed as a nozzle having a cavity and an outlet connected to the cavity. The outlet end of the pump mechanism 200 is connected to the cavity, thereby drawing liquid from the pump mechanism 200 and delivering liquid into the cavity, which then flows out from the outlet to perform water jet impact.

[0067] In some other embodiments, such as Figure 10As shown, the oral irrigator described above can also be configured as a combined rinsing and brushing device, which integrates the high-frequency vibration of an electric toothbrush with the pulsed water flow of a water flosser. Correspondingly, the care element 2000 can be constructed as a brush head, having bristles, a cavity, and an outlet communicating with the cavity, the outlet opening towards the bristles. The oral irrigator 1000 may also include a drive mechanism 400 with an output shaft, the output shaft being connected to and driving the care element 2000 to perform displacement movement, and the outlet end of the pump mechanism 200 communicating with the cavity through the flow channel of the output shaft, the pump mechanism 200 outputting a water flow impact through the outlet.

[0068] It should be noted that the drive mechanism 400 can be a motor, the output shaft is the motor shaft, the output shaft extends to the opposite ends of the drive mechanism 400 along the axial direction, and the flow channel of the output shaft passes through the opposite ends of the output shaft along the axial direction.

[0069] According to another aspect of this disclosure, a gripping member 100 is also provided. The gripping member 100 includes:

[0070] The main body 110 has a central axis 111, a accommodating cavity 112 and a liquid storage cavity 113 with an opening 1131. The liquid storage cavity 113 has a first inner wall surface 1132 and a second inner wall surface 1133. The first inner wall surface 1132 is located between the second inner wall surface 1133 and the opening 1131. The second inner wall surface 1133 is arranged closer to the central axis 111 than the first inner wall surface 1132.

[0071] The sealing member 120 has an insertion part 121, and a sealing element 130 is sleeved on the insertion part 121. The sealing member 120 is at least partially inserted into the liquid storage cavity 113 through the insertion part 121 and the opening 1131. The sealing element 130 is interference-fitted with the second inner wall surface 1133.

[0072] Furthermore, the first inner wall surface 1132 is inclined away from the second inner wall surface 1133 in a direction away from the central axis 111, or the first inner wall surface 1132 and the second inner wall surface 1133 are parallel to each other; and / or, the sealing element 130 includes a base 131 and a sealing portion 132, the base 131 is sleeved on the insertion portion 121, and the sealing portion 132 extends from the base 131 in a radially outward direction perpendicular to the central axis 111 and in a direction opposite to the insertion direction of the insertion portion 121.

[0073] It should be noted that the specific structure of the gripping component 100 can be found in the detailed description in the above embodiments, and will not be repeated here.

[0074] According to another aspect of this disclosure, an oral cleaning device 1000 is also provided, comprising a gripping component 100 and a pump mechanism 200. The gripping component 100 includes a main body 110 and a sealing element 120. The main body 110 has a central axis 111, a receiving cavity 112 for accommodating the pump mechanism 200, and a liquid storage cavity 113 having an opening 1131. The inlet end of the pump mechanism 200 communicates with the liquid storage cavity 113. The liquid storage cavity 113 has a first inner wall surface 1132, which converges inward from the opening 1131 towards the interior of the liquid storage cavity 113. The sealing element 120 has an insertion portion 121, on which a sealing element 130 is fitted. The sealing element 120 is at least partially inserted into the liquid storage cavity 113 through the insertion portion 121 and the opening 1131. The sealing element 130 is press-fitted with the first inner wall surface 1132.

[0075] In other words, the sealing element 130 can also be interference-fitted with the inclined first inner wall surface 1132. Thus, during the insertion of the insertion portion 121, which houses the sealing element 130, into the liquid storage cavity 113 through the opening 1131, the interference between the sealing element 130 and the first inner wall surface 1132 gradually decreases. This allows for easy installation and removal of the sealing component with minimal force without altering the sealing effect, improving the user experience.

[0076] It should be noted that the specific structure of the sealing element 120 and the sealing element 130 can be found in the detailed description in the above embodiments, and will not be repeated here.
