Description

Technical Field

[0001] This application relates to the field of toothbrush technology, and more particularly to a charging base and an electric toothbrush. Background Technology

[0002] Electric toothbrushes are widely used in daily life as a personal care household appliance. Electric toothbrushes can be charged wirelessly or wired. Among them, wireless charging electric toothbrushes are widely popular because they do not require an external charging port on the toothbrush itself.

[0003] In related technologies, wireless charging electric toothbrushes include a charging base and a toothbrush body. The charging components inside the charging base can wirelessly charge the toothbrush body, and the speaker on the charging base can emit sound to provide prompts and other functions. Therefore, the proper functioning of the speaker is particularly important. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a charging base and an electric toothbrush to reduce the impact of external debris on the loudspeaker, thereby ensuring the normal operation of the loudspeaker.

[0005] This application is achieved through the following technical solution.

[0006] In a first aspect, this application provides a charging dock, which includes a housing, a charging component, a speaker, and a sealing member. The housing has an internal cavity and a mating channel communicating with the inside and outside of the cavity. The charging component is disposed within the cavity for at least wireless connection with an electrical device outside the cavity. The speaker is disposed at the mating channel; the speaker includes a connected body and a sound outlet channel. The body is disposed within the cavity and electrically connected to the charging component; a first end of the sound outlet channel communicates with the sound outlet of the body, and a second end of the sound outlet channel extends into the mating channel. At least a portion of the sealing member is disposed between the sound outlet channel and the mating channel and is arranged circumferentially along the sound outlet channel.

[0007] In the technical solution of this application embodiment, the charging component and the speaker are disposed within the receiving cavity, so the outer shell can provide physical protection for the charging component and the speaker. The charging component can wirelessly charge electrical devices outside the receiving cavity, thus fulfilling the basic function of the charging dock. Since the speaker is electrically connected to the charging component, the speaker can also be powered by the charging component to produce sound. For example, the speaker can produce sound to provide prompts to the user, or it can produce sound to play music, thereby improving the intelligence level of the charging dock.

[0008] Specifically, since the mating channel connects the inside and outside of the receiving cavity, and the first end of the sound outlet channel is connected to the sound outlet of the main body, while the second end of the sound outlet channel extends into the mating channel, sound can be transmitted to the outside of the receiving cavity through the sound outlet channel after the main body emits sound, thus achieving sound emission. Furthermore, since at least a portion of the sealing element is located between the sound outlet channel and the mating channel, the sealing degree between them is improved, preventing debris from outside the receiving cavity from entering the cavity through the gap between the sound outlet channel and the mating channel. This ensures the normal operation of the main body and, consequently, the normal operation of the charging base. Through the mating arrangement of the sound outlet channel and the sealing element, a high degree of sealing is ensured while achieving sound emission.

[0009] In some embodiments of this application, the sealing element includes a first sealing portion and a second sealing portion connected together. Along the radial direction of the sound outlet channel, the first sealing portion is disposed between the outer peripheral wall surface of the sound outlet channel and the inner peripheral wall surface of the mating channel, and is disposed along the circumferential direction of the sound outlet channel. Along the extension direction of the mating channel, there is a sealing gap between the main body portion and the inner end face of the mating channel, and the sealing gap is disposed along the circumferential direction of the mating channel. The second sealing portion is disposed within the sealing gap and is disposed along the circumferential direction of the mating channel.

[0010] With this configuration, the first sealing part is located between the outer peripheral wall of the sound outlet channel and the inner peripheral wall of the mating channel, while the second sealing part is located between the inner end face of the mating channel and the main body. This achieves a double seal, thereby improving the sealing degree.

[0011] In some embodiments of this application, the first sealing portion has a first protrusion, which is arranged circumferentially along the sound outlet channel. The first sealing portion has a first protrusion on one side surface near the inner peripheral wall of the mating channel, and the first protrusion abuts against the inner peripheral wall of the mating channel; and / or, the first sealing portion has a first protrusion on one side surface near the outer peripheral wall of the sound outlet channel, and the first protrusion abuts against the outer peripheral wall of the sound outlet channel.

[0012] This design improves the tightness of the connection between the first sealing part and the outer peripheral wall of the sound outlet channel and the inner peripheral wall of the mating channel, thereby improving the stability of the first sealing part and its sealing performance.

[0013] In some embodiments of this application, the second sealing portion has a second protrusion, which is disposed circumferentially along the mating channel. The second sealing portion has a second protrusion on one side surface near the inner end face of the mating channel, and the second protrusion abuts against the inner end face of the mating channel; and / or, the second sealing portion has a second protrusion on one side surface near the body portion, and the second protrusion abuts against the body portion.

[0014] This configuration improves the tightness of the engagement between the inner end face of the second sealing part and the main body part in the mating channel, thereby increasing the stability of the second sealing part within the sealing gap and improving the sealing performance of the second sealing part.

[0015] In some embodiments of this application, a groove is formed on the outer peripheral wall of the sound outlet channel, and the groove is arranged circumferentially along the sound outlet channel. Along the radial direction of the sound outlet channel, a portion of the groove opening faces the inner peripheral wall of the mating channel, and the other portion of the groove opening is opposite to the sealing gap, with a first sealing part disposed within the groove.

[0016] This configuration allows the first sealing part to be positioned within the slot, ensuring its stability. Since the first and second sealing parts are connected, the overall stability of both is guaranteed. Furthermore, because the other part of the slot opening faces the sealing gap, it facilitates the entry of the second sealing part into the gap, thus ensuring ease of installation for both the first and second sealing parts.

[0017] In some embodiments of this application, the inner peripheral wall of the mating channel has a first snap-fit ​​portion, and the outer peripheral wall of the sound outlet channel has a second snap-fit ​​portion. Along the extension direction of the mating channel, the first snap-fit ​​portion and the second snap-fit ​​portion are opposite to each other and spaced apart to form a snap-fit ​​gap, and the sealing member is disposed in the snap-fit ​​gap.

[0018] With this configuration, during assembly, the seal can be placed on the side of the first snap-fit ​​part away from the main body. Then, the sound outlet channel is inserted into the mating channel from the inside of the receiving cavity. Since a snap-fit ​​gap is formed between the first snap-fit ​​part and the second snap-fit ​​part, the seal is located entirely within the snap-fit ​​gap after the sound outlet channel is inserted into place. This not only ensures the stability of the seal's placement but also facilitates installation.

[0019] In some embodiments of this application, the seal extends circumferentially around the sound outlet channel.

[0020] This configuration ensures a tight seal around the sound outlet channel.

[0021] In some embodiments of this application, the loudspeaker further includes a filter screen disposed within the sound outlet channel and located near the second end of the sound outlet channel.

[0022] With this setup, the filter can block debris from outside the cavity, reducing the probability of debris entering the sound outlet channel while ensuring sound output, thus preventing the sound outlet channel from being blocked.

[0023] In some embodiments of this application, a connector with a first mounting hole is formed on the main body, and a second mounting hole is formed on the outer shell. Fasteners pass through the first mounting hole and the second mounting hole to connect the connector and the outer shell.

[0024] With this configuration, the main body can be fastened to the outer casing, further ensuring the stability of the amplifier setup.

[0025] In some embodiments of this application, the outer shell has an inwardly recessed groove, and the second end of the mating channel is located at the bottom of the groove; the charging base also includes a protective member disposed in the groove, at least a portion of the protective member being opposite to the second end of the mating channel, and at least a portion of the protective member having a through hole communicating with the second end of the mating channel and the outside of the receiving cavity.

[0026] With this setup, the protective components still meet the sound output requirements, and the combination of the protective components and the grooves can achieve a certain level of protection and prevent debris from entering. At the same time, the protective components can also ensure the structural strength of the outer shell at the filter screen.

[0027] In some embodiments of this application, the charging assembly includes a charging module and a battery module. The battery module is electrically connected to the charging module and the main body to supply power to the charging module and the main body. The charging module is used for wireless connection with electrical devices outside the housing cavity.

[0028] With this setup, the charging module can wirelessly charge the device, while the battery module can power both the charging module and the main body. The battery module enhances the ease of use of the charging dock.

[0029] Secondly, this application provides an electric toothbrush, including a toothbrush body and a charging base as described in any of the above embodiments, wherein a charging component in the charging base is used for wireless connection with the toothbrush body.

[0030] In the technical solution of this application embodiment, the toothbrush body is charged by the charging base. Since the charging base in any of the above embodiments is included, the same beneficial effect can be achieved. Attached Figure Description

[0060] The following is a detailed description of this application.

[0061] Electric toothbrushes are widely used in daily life as a personal care household appliance. Electric toothbrushes can be charged wirelessly or wired. Among them, wireless charging electric toothbrushes are widely popular because they do not require an external charging port on the toothbrush itself.

[0062] Based on this, such as Figure 1 As shown, this application provides an electric toothbrush 100, which includes a toothbrush body 110 and a charging base 120. The charging component 122 in the charging base 120 is used for wireless connection with the toothbrush body 110.

[0063] The toothbrush body 110 refers to the part that the user can use to brush their teeth. It mainly includes a connected grip and a brush head. The grip has components such as a motor inside. The motor and other components can be connected to the brush head to drive the brush head and other parts to move. So when brushing teeth, the user can hold the grip and drive the brush head to move to complete brushing.

[0064] Additionally, the charging base 120 refers to a device that allows wireless charging of the toothbrush body 110 after it is placed on it. The charging base 120 mainly includes structures such as a charging coil 12212.

[0065] With the above settings, the toothbrush body 110 can be used for brushing teeth, and the charging base 120 can wirelessly charge the toothbrush body 110. Since the charging mode is wireless charging, it is convenient for users to use and improves the ease of use.

[0066] In related technologies, the wireless charging electric toothbrush 100 includes a charging base 120 and a toothbrush body 110. In addition to the charging component 122, the charging base 120 also has components such as a loudspeaker. The loudspeaker can emit sound to perform functions such as prompting, so the normal operation of the loudspeaker is particularly important.

[0067] Based on this, such as Figures 2-4 As shown, this application also provides a charging dock 120, which includes a housing 121, a charging assembly 122, a speaker 123, and a sealing member 124. The housing 121 has a receiving cavity a inside, and a mating channel b communicating with the inside and outside of the receiving cavity a. The charging assembly 122 is disposed in the receiving cavity a for at least wireless connection with an electrical device outside the receiving cavity a. The speaker 123 is disposed at the mating channel b; the speaker 123 includes a connected body portion 1231 and a sound outlet channel 1232. The body portion 1231 is disposed in the receiving cavity a and electrically connected to the charging assembly 122; the first end of the sound outlet channel 1232 communicates with the sound outlet of the body portion 1231, and the second end of the sound outlet channel 1232 extends into the mating channel b. At least a portion of the sealing member 124 is disposed between the sound outlet channel 1232 and the mating channel b, and is arranged circumferentially along the sound outlet channel 1232.

[0068] It should be explained that the mating channel b provided on the outer shell 121 should be a channel with a certain wall thickness. That is, the mating channel b is a channel with a solid structure, rather than a completely virtual space.

[0069] The aforementioned electrical device can be the toothbrush body 110, or any other device that requires electricity and is compatible with wireless charging.

[0070] Additionally, the outer casing 121 can be an elliptical structure. Multiple support pads can be provided at the bottom of the outer casing 121 to support it and ensure its stability. For example, four support pads can be provided. A charging surface is located on the upper part of the outer casing 121, opposite to the support pads. This allows the device to be placed on the charging surface for wireless charging.

[0071] In some examples, such as Figure 5 As shown, the charging assembly 122 includes a charging module 1221, which comprises a circuit board 12211, a charging coil 12212, and a magnet 12213. The circuit board 12211, charging coil 12212, and magnet 12213 are all located below the charging surface to facilitate a stable electrical connection with the toothbrush body 110. The circuit board 12211 provides relevant control, the charging coil 12212 provides wireless power supply, and the magnet 12213 provides an attractive force to the toothbrush body 110, enabling the toothbrush body 110 to automatically align and stably establish a stable wireless connection with the charging coil 12212. Wireless charging of the toothbrush body 110 is achieved through the cooperation of the circuit board 12211, charging coil 12212, and magnet 12213.

[0072] In addition, it is understandable that the main body 1231 refers to the component that can generate sound, and the sound output channel 1232 refers to the channel for transmitting sound.

[0073] In some examples, the output channels 1232 can be cylindrical ring structures, and correspondingly, the matching channel b can be a cylindrical ring structure.

[0074] In some examples, the material of the seal 124 can be a rubber elastomer or a plastic resin, etc.

[0075] In some examples, the sound outlet of the main body 1231 is located on the side close to the mating channel b, which facilitates the connection between the first end of the sound outlet channel 1232 and the sound outlet of the main body 1231.

[0076] With the above configuration, the charging component 122 and the speaker 123 are housed within the receiving cavity a, thus the outer casing 121 provides physical protection for the charging component 122 and the speaker 123. The charging component 122 can wirelessly charge devices outside the receiving cavity a, fulfilling the basic functions of the charging dock 120. Since the speaker 123 is electrically connected to the charging component 122, the speaker 123 can also be powered by the charging component 122 to produce sound. For example, the speaker 123 can emit sound to provide prompts to the user, or it can play music, thereby enhancing the intelligence level of the charging dock 120.

[0077] Specifically, since the mating channel b connects the inside and outside of the receiving cavity a, and the first end of the sound outlet channel 1232 is connected to the sound outlet of the main body 1231, and the second end of the sound outlet channel 1232 extends into the mating channel b, after the main body 1231 emits sound, the sound can be transmitted to the outside of the receiving cavity a through the sound outlet channel 1232, thereby achieving sound emission. Since at least a portion of the sealing member 124 is located between the sound outlet channel 1232 and the mating channel b, the sealing degree between the sound outlet channel 1232 and the mating channel b can be improved, thereby preventing debris from outside the receiving cavity a from entering the receiving cavity a through the gap between the sound outlet channel 1232 and the mating channel b. For example, the debris could be water or dust, thus ensuring the normal operation of the main body 1231, and consequently ensuring the normal operation of the charging base 120. Through the mating arrangement of the sound outlet channel 1232 and the sealing member 124, a sealing degree is ensured while achieving sound emission.

[0078] In some embodiments, such as Figure 4 , Figure 6 As shown, the loudspeaker 123 also includes a filter 1233, which is disposed in the sound outlet channel 1232 and located near the second end of the sound outlet channel 1232.

[0079] It is understandable that the filter screen 1233 has a large number of densely arranged pores, and the pore size of the pores can be selected according to the size of the impurities to be filtered.

[0080] In some examples, the filter 1233 is disposed on the end face of the second end of the sound outlet channel 1232 to cover the port of the second end of the sound outlet channel 1232. The shape of the filter 1233 can be curved or flat, depending on the shape of the surface where the second end of the sound outlet channel 1232 is located. Disposing the filter 1233 on the end face of the second end of the sound outlet channel 1232 facilitates its placement.

[0081] With the above configuration, since the filter screen 1233 has numerous pore structures, the pore structures can meet the sound output requirements. Since the filter screen 1233 has a filtering function, it can block debris outside the receiving cavity a, thereby reducing the amount of debris entering the inner part of the sound output channel 1232 through the second end of the sound output channel 1232, so as to avoid debris blocking the sound output channel 1232 and ensure normal sound output.

[0082] In some embodiments, such as Figure 6 As shown, a connector 12311 with a first mounting hole c is formed on the main body 1231, and a second mounting hole is formed on the outer shell 121. Fasteners pass through the first mounting hole c and the second mounting hole to connect the connector 12311 and the outer shell 121.

[0083] The number of connectors 12311 can be one or more. Each connector 12311 has a first mounting hole c. Correspondingly, the number of second mounting holes can also be one or more. Multiple first mounting holes c and multiple second mounting holes are set in a one-to-one correspondence. Each first mounting hole c and the corresponding second mounting hole are passed through a fastener, thereby realizing multi-position connection.

[0084] For example, the number of connectors 12311 can be two, three, four, or five, etc. Correspondingly, the number of second mounting holes can be two, three, four, or five, etc.

[0085] In some examples, there are two connectors 12311, which are respectively located on the upper and lower sides of the main body 1231. There are also two second mounting holes and two fasteners. The fasteners pass through the corresponding first and second mounting holes, thereby connecting the connectors 12311 to the outer shell 121, and thus connecting the main body 1231 to the outer shell 121. Because connectors 12311 are provided on both the upper and lower sides of the main body 1231, a tight connection can be ensured.

[0086] In some examples, there is a connecting post inside the housing 121, and the second mounting hole is set in the connecting post. Since the connecting post has a certain height, the structural strength of the connection can be guaranteed when using fasteners for connection.

[0087] In some examples, the connector 12311 is a protrusion, the fastener can be a bolt, and both the first mounting hole c and the second mounting hole are threaded holes. The bolt is used to achieve a threaded connection with the first mounting hole c and the second mounting hole respectively.

[0088] With the above configuration, since the connector 12311 is located on the main body 1231, the connection between the main body 1231 and the outer shell 121 can be achieved after connecting the outer shell 121 and the connector 12311 with fasteners. By connecting the main body 1231 and the outer shell 121 with fasteners, the stability of the amplifier is further guaranteed, thereby ensuring the stable sound output of the main body 1231.

[0089] In some embodiments, such as Figures 2-4 As shown, the outer casing 121 has an inwardly recessed groove d, and the second end of the mating channel b is located at the bottom of the groove d. Figures 8-10 As shown, the charging base 120 also includes a protective member 125, which is disposed in the groove d. At least a portion of the protective member 125 is opposite to the second end of the mating channel b, and at least a portion of the protective member 125 has a through hole e, which connects the second end of the mating channel b to the outside of the receiving cavity a.

[0090] In some examples, the surface of the protective member 125 facing away from the second end of the mating channel b is flush with the surface where the groove d is located. This arrangement of the protective member 125 can ensure that the outer surface of the housing 121 and the protective member 125 as a whole is flat, which can make the charging base 120 more aesthetically pleasing.

[0091] In some examples, the protective element 125 may have multiple through holes e, which are arranged in a circular array on the protective element 125. The diameter of the through holes e must be controlled to not only meet the sound output requirements but also reduce the probability of foreign objects entering.

[0092] With the above configuration, since the protective component 125 has a through hole e connecting the second end of the mating channel b to the outside of the receiving cavity a, the through hole e can meet the sound output requirements. Moreover, the mating configuration of the protective component 125 and the groove d can achieve a certain protection and anti-debris effect. At the same time, the configuration of the protective component 125 can also ensure the structural strength of the outer shell 121 at the filter screen 1233.

[0093] In some embodiments, such as Figure 9 As shown, the charging assembly 122 includes a charging module 1221 and a battery module 1222. The battery module 1222 is electrically connected to the charging module 1221 and the main body 1231 to supply power to the charging module 1221 and the main body 1231. The charging module 1221 is used for wireless connection with electrical equipment outside the receiving cavity a.

[0094] It is understandable that battery module 1222 refers to a battery with energy storage capacity, such as a lithium battery or a lead-acid battery.

[0095] In some examples, the battery module 1222 is located on the side of the circuit board 12211, the charging coil 12212, and the magnet 12213 away from the mating surface, while the loudspeaker and its corresponding mating channel b are located on the side. This facilitates the overall spatial layout within the cavity a and ensures tight integration.

[0096] In some examples, such as Figure 9 As shown, the charging assembly 122 also includes a counterweight shell 1223, which houses the battery module 1222, circuit board 12211, charging coil 12212, and magnet 12213. This modular design facilitates the installation and removal of the battery module 1222, circuit board 12211, charging coil 12212, and magnet 12213. Furthermore, the counterweight shell 1223 helps to balance the overall weight of the charging base 120, preventing the toothbrush body 110 from tilting during charging and ensuring the stability of the charging base 120 during placement and charging. For example, the counterweight shell 1223 can be made of metal or similar materials.

[0097] With the above configuration, the battery module 1222 can supply power to the charging module 1221 and the main body 1231, while the charging module 1221 can wirelessly charge the device, thus ensuring the basic functions of the charging dock 120. The charging module 1221 can also supply power to the main body 1231 to ensure that the main body 1231 can emit sound normally. The battery module 1222 allows the charging dock 120 to adapt to various complex environments, improving its ease of use.

[0098] The seal 124 is arranged circumferentially along the sound outlet channel 1232. The seal 124 can be a ring structure, or the seal 124 can be a structure of multiple blocks. The following is a detailed description.

[0099] In some embodiments, such as Figure 10 , Figure 11 As shown, the seal 124 extends circumferentially along the sound outlet channel 1232.

[0100] In other words, the seal 124 is a ring structure, and the shape of the ring structure needs to be determined according to the shape of the cross-section of the sound outlet channel 1232.

[0101] With the above configuration, the seal 124 is a ring structure. The ring structure of the seal 124 can ensure the sealing degree of the seal 124 around the sound outlet channel 1232, thus improving the sealing performance of the seal 124.

[0102] Of course, in other embodiments, the seal 124 may also include a plurality of sealing blocks arranged circumferentially along the sound outlet channel 1232, so that the sound outlet channel 1232 and the mating channel b can be sealed around the circumference using the plurality of sealing blocks.

[0103] There are various ways to set the seal 124. The following describes the setting methods of the seal 124 in combination with different implementation methods.

[0104] In some embodiments, such as Figure 4 , Figures 12-16 As shown, the sealing element 124 includes a first sealing part 1241 and a second sealing part 1242 connected together. Along the radial direction of the sound outlet channel 1232, the first sealing part 1241 is disposed between the outer peripheral wall surface of the sound outlet channel 1232 and the inner peripheral wall surface of the mating channel b, and is disposed along the circumferential direction of the sound outlet channel 1232. Along the extension direction of the mating channel b, there is a sealing gap f between the body part 1231 and the inner end face of the mating channel b, and the sealing gap f is disposed along the circumferential direction of the mating channel b. The second sealing part 1242 is disposed in the sealing gap f and is disposed along the circumferential direction of the mating channel b.

[0105] It is understandable that the outer peripheral wall of the sound outlet channel 1232 refers to the wall surrounding the outer periphery of the sound outlet channel 1232, and the inner peripheral wall of the mating channel b refers to the wall surrounding the inner periphery of the mating channel b. The inner end face of the mating channel b refers to the end face of the mating channel b located inside the receiving cavity a.

[0106] The first sealing part 1241 can be arranged circumferentially along the sound outlet channel 1232, extending around the entire circumference of the sound outlet channel 1232. This ensures a tight seal between the outer circumferential wall of the sound outlet channel 1232 and the inner circumferential wall of the mating channel b. Alternatively, the first sealing part 1241 can be arranged circumferentially along the sound outlet channel 1232, comprising multiple first sub-blocks arranged sequentially along the circumference of the sound outlet channel 1232. This seals the gap between the outer circumferential wall of the sound outlet channel 1232 and the inner circumferential wall of the mating channel b.

[0107] Alternatively, the second sealing portion 1242 can be arranged circumferentially along the mating channel b, extending around the entire circumference of the mating channel b. This ensures a circumferential seal between the main body 1231 and the inner end face of the mating channel b. Alternatively, the second sealing portion 1242 can include multiple second sub-blocks arranged sequentially along the circumference of the mating channel b, thereby sealing the gap between the main body 1231 and the inner end face of the mating channel b.

[0108] It is understandable that when the seal 124 extends circumferentially along the sound outlet channel 1232, the first sealing part 1241 extends circumferentially along the sound outlet channel 1232, and at the same time, the second sealing part 1242 extends circumferentially along the mating channel b.

[0109] With the above configuration, the first sealing part 1241 is sealed between the outer peripheral wall of the sound outlet channel 1232 and the inner peripheral wall of the mating channel b, thereby sealing the gap between the outer peripheral wall of the sound outlet channel 1232 and the inner peripheral wall of the mating channel b. The second sealing part 1242 is sealed between the inner end face of the mating channel b and the body part 1231, thereby sealing the sealing gap f between the inner end face of the mating channel b and the body part 1231. This achieves double sealing, thereby improving the sealing degree.

[0110] In some embodiments, such as Figures 13-16 As shown, the first sealing portion 1241 has a first protrusion 12411, which is arranged circumferentially along the sound outlet channel 1232. The first sealing portion 1241 has the first protrusion 12411 on one side of its inner peripheral wall near the mating channel b, and the first protrusion 12411 abuts against the inner peripheral wall of the mating channel b. And / or, the first sealing portion 1241 has the first protrusion 12411 on one side of its outer peripheral wall near the sound outlet channel 1232, and the first protrusion 12411 abuts against the outer peripheral wall of the sound outlet channel 1232.

[0111] In other words, the above embodiments include three types: First, the surface of the first sealing part 1241 near the inner peripheral wall of the mating channel b has a first protrusion 12411. Second, the surface of the first sealing part 1241 near the outer peripheral wall of the sound outlet channel 1232 has a first protrusion 12411. Third, the surface of the first sealing part 1241 near the inner peripheral wall of the mating channel b has a first protrusion 12411. Simultaneously, the surface of the first sealing part 1241 near the outer peripheral wall of the sound outlet channel 1232 also has a first protrusion 12411.

[0112] In some examples, the first protrusion 12411 is part of the first sealing part 1241. Both the first sealing part 1241 and the first protrusion 12411 are elastic sealing components. Thus, after the first protrusion 12411 is provided, the first protrusion 12411 can be pressed between the first sealing part 1241 and the outer peripheral wall of the sound outlet channel 1232, or the first protrusion 12411 can be pressed between the first sealing part 1241 and the inner peripheral wall of the mating channel b. This can improve the sealing performance between the outer peripheral wall of the sound outlet channel 1232 and the inner peripheral wall of the mating channel b.

[0113] In addition, the first protrusion 12411 is arranged circumferentially along the sound outlet channel 1232. This means the first protrusion 12411 can extend circumferentially around the sound outlet channel 1232, thus ensuring a tight seal and thus guaranteeing the degree of sealing. Alternatively, the first protrusion 12411 may also include multiple first sub-protrusions, which are arranged circumferentially along the sound outlet channel 1232.

[0114] With the above configuration, the first protrusion 12411 can improve the tightness of the engagement between the first sealing part 1241 on the outer peripheral wall of the sound outlet channel 1232 and the inner peripheral wall of the mating channel b, thereby improving the stability of the first sealing part 1241 and the sealing degree of the first sealing part 1241.

[0115] In some embodiments, such as Figures 13-16 As shown, the second sealing portion 1242 has a second protrusion 12421, which is arranged circumferentially along the mating channel b. The second sealing portion 1242 has the second protrusion 12421 on one side surface near the inner end face of the mating channel b, and the second protrusion 12421 abuts against the inner end face of the mating channel b. And / or, the second sealing portion 1242 has the second protrusion 12421 on one side surface near the body portion 1231, and the second protrusion 12421 abuts against the body portion 1231.

[0116] In other words, the above embodiments include three types: First, the second sealing portion 1242 has a second protrusion 12421 on one side of its surface near the inner end face of the mating channel b. Second, the second sealing portion 1242 has a second protrusion 12421 on one side of its surface near the body portion 1231. Third, the second sealing portion 1242 has a second protrusion 12421 on one side of its surface near the inner end face of the mating channel b. Simultaneously, the second sealing portion 1242 also has a second protrusion 12421 on one side of its surface near the body portion 1231.

[0117] In some examples, the second protrusion 12421 is part of the second sealing portion 1242. Both the second sealing portion 1242 and the second protrusion 12421 are elastic sealing components. Thus, after the second protrusion 12421 is provided, the second protrusion 12421 can be pressed between the inner end face of the mating channel b and the second sealing portion 1242. Alternatively, the second protrusion 12421 can be pressed between the second sealing portion 1242 and the body portion 1231, thereby improving the sealing performance between the inner end face of the mating channel b and the body portion 1231.

[0118] Additionally, the second protrusion 12421 is arranged circumferentially along the mating channel b, which can extend around the circumference of the mating channel b. This ensures the sealing performance of the contact and thus guarantees the degree of sealing. Alternatively, the second protrusion 12421 may also include multiple second sub-protrusions, which are arranged circumferentially along the mating channel b.

[0119] With the above configuration, the second protrusion 12421 can improve the tightness of the engagement between the second sealing part 1242 and the body part 1231 in the mating channel b, thereby improving the stability of the second sealing part 1242 in the sealing gap f and improving the sealing degree of the second sealing part 1242.

[0120] To ensure the stability of the seal 124, a special structural design is required, which will be described in detail below.

[0121] In some embodiments, such as Figure 13 , Figure 14 As shown, a groove g is formed on the outer peripheral wall of the sound outlet channel 1232, and the groove g is arranged circumferentially along the sound outlet channel 1232. Along the radial direction of the sound outlet channel 1232, a portion of the groove opening of the groove g faces the inner peripheral wall of the mating channel b, and the other portion of the groove opening of the groove g is opposite to the sealing gap f. The first sealing part 1241 is provided in the groove g.

[0122] The card slot g can extend around the sound outlet channel 1232, which facilitates the setting of the first sealing part 1241.

[0123] In some examples, along the extension direction of the sound outlet channel 1232, the slot g extends from the intersection of the body portion 1231 and the sound outlet channel 1232 toward the second end of the sound outlet channel 1232.

[0124] With the above configuration, the first sealing part 1241 can be placed within the slot g, thereby ensuring the stability of the first sealing part 1241. Since the first sealing part 1241 and the second sealing part 1242 are connected, the overall stability of the first sealing part 1241 and the second sealing part 1242 can be guaranteed. Moreover, since the other part of the slot opening of the slot g is opposite to the sealing gap f, it is also convenient for the second sealing part 1242 to enter the sealing gap f, thus ensuring the ease of installation of the first sealing part 1241 and the second sealing part 1242.

[0125] Specifically, during installation, the first sealing part 1241 is first fitted into the slot g, and the second sealing part 1242 is also fitted onto the sound outlet channel 1232. Then, from the inside of the receiving cavity a, along the extension direction of the mating channel b, the sound outlet channel 1232 is inserted into the mating channel b. After being inserted into place, the second sealing part 1242 is just engaged between the body part 1231 and the inner end face of the mating channel b, that is, the second sealing part 1242 is just located within the sealing gap f.

[0126] In some embodiments, such as Figure 10 , Figures 17-18 As shown, the inner peripheral wall of the mating channel b has a first snap-fit ​​portion b1, and the outer peripheral wall of the sound output channel 1232 has a second snap-fit ​​portion 12321. Along the extension direction of the mating channel b, the first snap-fit ​​portion b1 and the second snap-fit ​​portion 12321 are opposite to each other and spaced apart to form a snap-fit ​​gap h. The sealing member 124 is disposed in the snap-fit ​​gap h.

[0127] In other words, along the extension direction of the mating channel b, the seal 124 is engaged between the first engaging portion b1 and the second engaging portion 12321.

[0128] Among them, the sealing element 124 can be an annular sealing ring.

[0129] With the above configuration, during assembly, the sealing element 124 can be placed on the side of the first snap-fit ​​part b1 away from the main body part 1231. Then, the sound outlet channel 1232 is inserted into the mating channel b from the inside of the receiving cavity a. Since a snap-fit ​​gap h is formed between the first snap-fit ​​part b1 and the second snap-fit ​​part 12321, the sealing element 124 is located entirely within the snap-fit ​​gap h after the sound outlet channel 1232 is inserted into place. This not only ensures the stability of the sealing element 124 but also facilitates installation.

[0130] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
