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 base houses a charging module and a connector for electrical connection. The charging base has an external connection hole, and the connector is located at the external connection hole. In this way, the charging module can interact with external devices through the connector, such as supplying power to the charging module through the connector, and then using the charging module to wirelessly charge external electrical devices.

[0004] However, due to the external port, debris may come into contact with the connector through the external port, which may affect the connector and thus affect the normal operation of the charging dock. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a charging base and an electric toothbrush to prevent external debris from affecting the internal connectors of the charging base, thereby ensuring the normal operation of the charging base.

[0006] This application is achieved through the following technical solution.

[0007] In a first aspect, this application provides a charging dock, which includes a housing, a charging assembly, and a blocking structure. The housing has an internal cavity and an external connection hole communicating with the inside and outside of the cavity. The charging assembly includes a charging module and a connector. The charging module is disposed within the cavity for wireless connection to an external electrical device. The connector is disposed within the cavity, located at the external connection hole, and electrically connected to the charging module. At least part of the blocking structure is detachably disposed within the external connection hole to block it.

[0008] In the technical solution of this application embodiment, the charging module and connector are disposed within the receiving cavity, so the outer shell can provide physical protection for the charging module and connector. Since the connector is electrically connected to the charging module, after the blocking structure is removed from the external hole, the charging module can interact with other external devices through the connector. For example, the connector can be connected to a power source, so the charging module can connect to the power source through the connector to wirelessly charge the device.

[0009] When charging is not required, the blocking structure seals the external port, preventing external debris from contacting the connector through the external port. This ensures that the connector is not affected by external debris, allowing it to work normally for a long time, and thus ensuring the normal operation of the charging base.

[0010] In some embodiments of this application, the outer surface of the housing includes a mating surface, and the external access hole is located on the mating surface. The blocking structure includes a connecting portion and a blocking portion connected together. The blocking portion is disposed in the external access hole to block the external access hole; the connecting portion is disposed on the side of the blocking portion away from the receiving cavity and abuts against the mating surface.

[0011] With this configuration, the sealing part is responsible for sealing the external connection hole, while the connecting part can abut against the mating surface to ensure that the sealing part can seal in place. Through the combination of the sealing part and the connecting part, not only can the external connection hole be sealed, but it can also facilitate actual operation.

[0012] In some embodiments of this application, the charging base further includes a guide hole and a guide protrusion. One of the guide hole and the guide protrusion is located on the side of the connecting portion near the mating surface, and the other is located on the mating surface. The guide protrusion extends in a direction parallel to the extension direction of the external hole and extends into the guide hole.

[0013] With this configuration, when using the sealing part to seal the external connection hole, the guide protrusion can first enter the guide hole, and then the connecting part can be moved under the guidance of the guide protrusion and the guide hole, thereby driving the sealing part connected to the connecting part into the external connection hole to achieve sealing. This can further improve the convenience of operation.

[0014] In some embodiments of this application, the sealing portion is connected to an abutment protrusion, which is arranged circumferentially along the outer hole and abuts against the inner wall surface of the sealing portion and the outer hole.

[0015] With this design, after the sealing part enters the external connection hole, it can achieve a tight fit with the inner wall surface of the external connection hole by abutting the protrusion, thereby ensuring the sealing performance and the detachability of the sealing part from the external connection hole.

[0016] In some embodiments of this application, the outer shell has an inwardly recessed groove, and the mating surface is located at the bottom of the groove; the connecting part is disposed in the groove.

[0017] This design, by creating a groove on the outer shell and placing the connecting part inside the groove, prevents the connecting part from protruding from the surface where the groove opening is located, thereby improving the overall flatness of the outer side of the outer shell and the connecting part.

[0018] In some embodiments of this application, the peripheral wall of the groove is clearance-fitted with the connecting portion; the charging base also includes a mating component disposed in the gap between the peripheral wall of the groove and the connecting portion.

[0019] With this design, the mating parts can not only seal the groove's peripheral wall and the connecting part, but also have a certain decorative effect.

[0020] In some embodiments of this application, the side surface of the connecting portion away from the mating surface is flush with the surface where the groove is located.

[0021] With this design, the outer surface of the connector is flush with the surface where the groove is located, which can further improve the overall flatness of the outer side of the shell and the connector.

[0022] In some embodiments of this application, the connecting portion has an inwardly recessed gripping groove formed on the side facing the peripheral wall of the groove, and the connecting portion is used to be gripped through the gripping groove.

[0023] With this configuration, the connecting part can be held in the grip groove to facilitate movement of the connecting part, thereby moving the sealing part to block the external connection hole, or moving the sealing part out of the external connection hole.

[0024] In some embodiments of this application, the gripping groove extends through the connecting portion along the groove depth direction, and the edge of the gripping groove near the mating surface has a notch communicating with the gripping groove.

[0025] With this design, the connecting part of the notch can be gripped by entering the notch through the grip groove.

[0026] In some embodiments of this application, the connecting part includes a connected support body and a connecting body, a supporting space is formed on the connecting body, the support body is disposed in the supporting space to support at least one of the connecting body and the sealing part, and the sealing part is connected to the connecting body.

[0027] With this configuration, the connecting part includes two parts: a support body and a connecting body. The connecting body serves to connect the sealing part, while the support body provides support for at least one of the connecting body and the sealing part. This not only ensures the normal functioning of the connecting part and the sealing part, but also guarantees the overall structural strength of the blocking structure.

[0028] In some embodiments of this application, the connecting body has an inwardly recessed support space on the side near the sealing part, the sealing part is connected to the bottom of the support space, the support body has a clearance hole, the support body is sleeved on the sealing part through the clearance hole, the inner wall surface of the clearance hole abuts against the sealing part, and the support body abuts against the peripheral wall surface of the support space.

[0029] With this configuration, by opening clearance holes in the support body, the support body can be fitted onto the sealing part through the clearance holes, so that the support body can provide support for the sealing part. At the same time, the connecting body provides support for the peripheral wall surface of the support space, thereby achieving support for the connecting body. In this way, the support body can provide support for both the connecting body and the sealing part simultaneously.

[0030] In some embodiments of this application, at least a portion of the blocking structure has a mating hole located on the side of the blocking structure closer to the connector, and at least a portion of the connector extends into the mating hole.

[0031] With this configuration, after at least part of the blocking structure is sealed inside the external hole, the connector can extend into the mating hole, thus achieving precise alignment, avoiding unnecessary wear on the connector and the blocking structure, and further improving the protection of the connector.

[0032] In some embodiments of this application, the charging assembly further includes a battery module disposed within a receiving cavity, a connector electrically connected to the battery module, and the battery module electrically connected to the charging module.

[0033] With this setup, the battery module can be used to store electrical energy. Even if the charging dock cannot be connected to a power source, the battery module can still provide power to the charging module, which in turn can be used to charge the device.

[0034] Secondly, this application provides an electric toothbrush, including a toothbrush body and a charging base. The charging base is the charging base in any of the above embodiments, and the charging module in the charging base is used for wireless connection with the toothbrush body.

[0035] 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 module 1221 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 convenience.

[0066] In related technologies, the charging base 120 internally houses a charging module 1221 and a connector 1222 that are electrically connected. The charging base 120 has an external connection hole b, and the connector 1222 is disposed at the external connection hole b. Thus, the charging module 1221 can interact with external devices through the connector 1222. For example, the connector 1222 can be electrically connected to an external power source to supply power to the charging module 1221, thereby using the charging module 1221 to wirelessly charge the toothbrush body 110.

[0067] However, due to the design of the external port b, debris may come into contact with the connector 1222 through the external port b, which will affect the connector 1222 and thus affect the normal operation of the charging base 120.

[0068] Based on this, such as Figure 2 , Figure 3 As shown, this application also provides a charging dock 120, which includes a housing 121, a charging assembly 122, and a blocking structure 123. The housing 121 has a receiving cavity a inside, and an external connection hole b communicating with the inside and outside of the receiving cavity a. The charging assembly 122 includes a charging module 1221 and a connector 1222. The charging module 1221 is disposed in the receiving cavity a for wireless connection with an electrical device outside the receiving cavity a; the connector 1222 is disposed in the receiving cavity a and located at the external connection hole b, and is electrically connected to the charging module 1221. At least a portion of the blocking structure 123 is detachably disposed in the external connection hole b to block the external connection hole b.

[0069] It should be explained that "connector 1222 is located at the external connection hole b" means that along the extension direction of the external connection hole b, connector 1222 is located within the range of the external connection hole b. Connector 1222 may partially extend into the external connection hole b, but this extension should not affect the blocking structure 123's ability to seal the external connection hole b. Of course, connector 1222 may also not extend into the external connection hole b, meaning connector 1222 is completely located within the receiving cavity a.

[0070] The aforementioned electrical device can be the toothbrush body 110, or any other device that requires electricity and is compatible with wireless charging.

[0071] 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.

[0072] In some examples, such as Figure 2 As shown, the charging module 1221 includes 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.

[0073] In some examples, connector 1222 can be a charging interface. Specifically, connector 1222 is connected to an external power source via a wire, thereby powering the charging module 1221. Connector 1222 can also be an interface capable of charging externally. In this case, the charging assembly 122 also needs to include a battery module 1223, which stores electrical energy. Connector 1222 is electrically connected to the charging module 1221 via the battery module 1223. Thus, the battery module 1223 can be connected to an external power device via a wire, allowing the connector 1222 to charge the external power device from the internal power of the battery module 1223. The power device here does not refer to the toothbrush body 110 mentioned above, but to other devices that use wires for charging, such as Bluetooth headsets.

[0074] The connector 1222 can be either a USB interface or a Type-C interface. It is understood that the connector 1222 is electrically connected to external devices via wires, and the connector 1222 and the wires are detachably connected.

[0075] In some examples, the blocking structure 123 may be formed of soft plastic, which facilitates the blocking structure 123 in sealing the external hole b. Alternatively, the blocking structure 123 may be composed of a combination of soft plastic and rigid structural components, which not only achieves the sealing of the external hole b but also ensures the overall structural strength of the blocking structure 123.

[0076] With the above configuration, the charging module 1221 and connector 1222 are housed within the receiving cavity a, thus the outer shell 121 can provide physical protection for the charging module 1221 and connector 1222. Since the connector 1222 is electrically connected to the charging module 1221, after the blocking structure 123 is removed from the external connection hole b, the charging module 1221 can interact with other external devices through the connector 1222. For example, the connector 1222 can be connected to a power source, thus enabling the charging module 1221 to connect to the power source and wirelessly charge the device.

[0077] When charging is not required, the blocking structure 123 blocks the external port b, thus preventing external debris from contacting the connector 1222 through the external port b. The debris can be water, dust, etc., thereby ensuring that the connector 1222 is not affected by external debris, ensuring its long-term normal operation, and thus ensuring the normal operation of the charging base 120.

[0078] In some embodiments, such as Figure 2As shown, the charging assembly 122 also includes a battery module 1223, which is disposed in the receiving cavity a. The connector 1222 is electrically connected to the battery module 1223, and the battery module 1223 is electrically connected to the charging module 1221.

[0079] It is understandable that battery module 1223 refers to a battery with energy storage capacity, such as a lithium battery or a lead-acid battery.

[0080] In some examples, the battery module 1223 is located on the side of the circuit board 12211, the charging coil 12212, and the magnet 12213 away from the mating surface d, while the connector 1222 and its corresponding external interface are located on the side. This facilitates the overall spatial layout within the cavity a and ensures tight integration.

[0081] In some examples, such as Figure 2 As shown, the charging assembly 122 also includes a counterweight shell 1224, which houses the battery module 1223, circuit board 12211, charging coil 12212, and magnet 12213. This modular design facilitates the installation and removal of the battery module 1223, circuit board 12211, charging coil 12212, and magnet 12213. Furthermore, the counterweight shell 1224 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 1224 can be made of metal or similar materials.

[0082] With the above settings, connector 1222 can charge battery module 1223, and battery module 1223 can be used to store electrical energy. In this way, even if the charging base 120 cannot be connected to the power source, it can still provide power to charging module 1221 through battery module 1223, and then use charging module 1221 to charge toothbrush body 110. This allows charging base 120 to adapt to various complex environments.

[0083] In some embodiments, such as Figures 3-5 As shown, at least a portion of the blocking structure 123 has a mating hole c, which is located on the side of the blocking structure 123 near the connector 1222, and at least a portion of the connector 1222 extends into the mating hole c.

[0084] It is understood that at least a portion of the blocking structure 123 refers to the portion that is sealed inside the external hole b.

[0085] In some examples, connector 1222 includes a conductive post extending in the same direction as the external hole b, and a mating hole c extending in the same direction as the conductive post. The mating hole c is a blind hole, the conductive post extends into the mating hole c, and the conductive post and the mating hole c are matched.

[0086] With the above configuration, after at least a portion of the blocking structure 123 is sealed inside the external hole b, the connector 1222 can extend into the mating hole c. This allows for precise alignment, avoids unnecessary wear on the connector 1222 and the blocking structure 123, and further improves the protection of the connector 1222.

[0087] In some embodiments, such as Figures 6-10 As shown, the outer surface of the outer casing 121 includes a mating surface d, and the external connection hole b is located on the mating surface d. The blocking structure 123 includes a connecting portion 1231 and a blocking portion 1232 connected together. The blocking portion 1232 is disposed in the external connection hole b to block the external connection hole b. The connecting portion 1231 is disposed on the side of the blocking portion 1232 away from the receiving cavity a, and abuts against the mating surface d.

[0088] For ease of understanding, it can be described as follows: Figure 6 The vertical dotted line in the diagram divides the blocking structure 123 into a connecting part 1231 and a blocking part 1232. However, it is understandable that the division of the connecting part 1231 and the blocking part 1232 is not limited to this.

[0089] In addition, the mating of the connecting part 1231 and the mating surface d does not necessarily mean that the opposite parts of the two are completely fitted together; it can be a partial mating.

[0090] In some examples, at least a portion of the blocking structure 123 has a mating hole c. In the case where the blocking structure 123 includes a connecting portion 1231 and a blocking portion 1232, the mating hole c is provided on the blocking portion 1232.

[0091] With the above configuration, the sealing part 1232 is responsible for sealing the external connection hole b, while the connecting part 1231 can abut against the mating surface d to ensure that the sealing part 1232 can be sealed in place. Through the combination of the sealing part 1232 and the connecting part 1231, not only can the external connection hole b be sealed, but it can also facilitate actual operation.

[0092] In some embodiments, such as Figure 4 , Figure 9 , Figure 10As shown, the charging base 120 also includes a guide hole 124 and a guide protrusion 125. One of the guide hole 124 and the guide protrusion 125 is located on the side of the connecting portion 1231 near the mating surface d, and the other is located on the mating surface d. The guide protrusion 125 extends in a direction parallel to the extension direction of the external hole b and extends into the guide hole 124.

[0093] It is understandable that the extension directions of the guide protrusion 125 and the guide hole 124 should be consistent.

[0094] In other words, the above embodiments include two schemes. The first scheme: a guide protrusion 125 is provided on the connecting portion 1231, and a guide hole 124 is provided on the mating surface d. The second scheme: a guide protrusion 125 is provided on the mating surface d, and a guide hole 124 is provided on the connecting portion 1231. For ease of understanding, the accompanying drawings of this application all illustrate the first scheme.

[0095] The shapes of the guide protrusion 125 and the guide hole 124 can be arbitrary, as long as they can cooperate to perform the guiding function. For example, if the guide protrusion 125 is a plate-like structure, then the guide hole 124 is also a plate-like hole.

[0096] In some examples, a guide protrusion 125 is provided on the connecting portion 1231, and the guide protrusion 125 has a weight-reducing hole w, which can reduce the overall weight of the blocking structure 123, thereby facilitating operation.

[0097] For example, the number of weight-reducing holes w can be multiple, the guide protrusion 125 is a plate-like structure, and the multiple weight-reducing holes w are arranged in the plane of the plate-like structure and are spaced apart in any direction.

[0098] For example, the shape of the weight-reducing hole w can be a regular shape such as a circle or a square. Alternatively, it can be an irregular shape.

[0099] In addition, the guide hole 124 can be a through hole or a blind hole, and the specific choice can be made according to the actual situation.

[0100] With the above configuration, when using the sealing part 1232 to seal the external connection hole b, the guide protrusion 125 can first enter the guide hole 124, and then the connecting part 1231 can be moved under the guidance of the guide protrusion 125 and the guide hole 124, thereby driving the sealing part 1232 connected to the connecting part 1231 into the external connection hole b to achieve sealing, which can further improve the convenience of operation.

[0101] In some embodiments, such as Figure 4 , Figure 6 , Figure 10As shown, the sealing part 1232 is connected to an abutting protrusion 12321, which is arranged along the circumference of the external hole b and abuts against the inner wall surface of the sealing part 1232 and the external hole b.

[0102] In some examples, the abutment protrusion 12321 is an elastic structure, so that after the sealing part 1232 enters the external hole b, the abutment protrusion 12321 can deform to press between the sealing part 1232 and the inner wall surface of the external hole b.

[0103] The abutment protrusion 12321 can extend circumferentially around the external hole b, thus ensuring a tight fit between the sealing part 1232 and the external hole b. Alternatively, the abutment protrusion 12321 can also include multiple sub-protrusions, which are arranged sequentially along the circumferential direction of the external hole b, and each sub-protrusion abuts against the inner wall surface of the sealing part 1232 and the external hole b.

[0104] With the above configuration, after the sealing part 1232 enters the external connection hole b, it can achieve a tight fit with the inner wall surface of the external connection hole b by abutting the protrusion 12321, thereby ensuring the sealing performance and the detachability of the sealing part 1232 and the external connection hole b.

[0105] In some embodiments, such as Figures 7-9 As shown, the outer casing 121 has an inwardly recessed groove e, and the mating surface d is located at the bottom of the groove e. The connecting part 1231 is provided in the groove e.

[0106] It is understood that the groove e is located on the outside of the outer casing 121, and the opening of the groove e can be any suitable shape, specifically selected and set according to the shape of the outer casing 121. The groove depth of the groove e can be selected according to the dimension of the connecting part 1231 in the groove depth direction.

[0107] By setting the above configuration, and by providing a groove e on the outer shell 121 and placing the connecting part 1231 inside the groove e, the connecting part 1231 can be prevented from protruding from the surface where the groove e is located, thereby improving the overall flatness of the outer shell 121 and the connecting part 1231 and enhancing the aesthetics.

[0108] In some embodiments, such as Figure 11 As shown, the side surface of the connecting part 1231 facing away from the mating surface d is flush with the surface where the groove e is located.

[0109] In other words, the groove e on the outer shell 121 is filled by the connecting part 1231, so that the entire outer side of the outer shell 121 is a flat arc-shaped surface or a plane.

[0110] With the above configuration, the outer surface of the connecting part 1231 and the surface where the groove e is located are flush, which can further improve the overall flatness of the outer side of the outer shell 121 and the connecting part 1231 and improve the aesthetics.

[0111] In some embodiments, such as Figure 4 , Figure 11 As shown, the peripheral wall of the groove e is in clearance fit with the connecting part 1231. The charging base 120 also includes a mating part 126, which is disposed in the gap between the peripheral wall of the groove e and the connecting part 1231.

[0112] The mating part 126 may serve only a decorative purpose, or it may serve a sealing purpose to improve the sealing performance.

[0113] In some examples, the side surface of the mating part 126 facing away from the bottom of the groove e can be flush with the plane where the groove e is located. This not only improves the aesthetics or achieves a seal by setting the mating part 126, but also ensures the overall flatness of the outer side of the outer shell 121, thereby improving the aesthetics.

[0114] With the above configuration, the mating part 126 can not only seal the peripheral wall of the groove e and the connecting part 1231, but also has a certain decorative effect.

[0115] To facilitate the movement of the blocking structure 123, a gripping groove f or a handle or similar structure can be provided on the blocking structure 123 to facilitate its movement. This allows at least a portion of the blocking structure 123 to be sealed within the external hole b, or at least a portion of the blocking structure 123 to be removed from the external hole b. This will be described below.

[0116] In some embodiments, such as Figure 4 , Figures 8-11 As shown, the connecting part 1231 has an inwardly recessed gripping groove f on the side facing the peripheral wall of the groove e, and the connecting part 1231 is used to be gripped through the gripping groove f.

[0117] In other words, a gripping groove f is provided at the edge of the connecting part 1231. When the user needs to move the blocking structure 123, he / she can put his / her hand into the gripping groove f, and then grip the connecting part 1231 tightly. Then, he / she applies force to the connecting part 1231 to drive the sealing part 1232 into the external hole b, or drive the sealing part 1232 out of the external hole b.

[0118] The gripping groove f can be provided on the upper side, lower side, or left and right sides of the connecting part 1231. For ease of understanding, the gripping groove f in this application is provided on the lower side of the connecting part 1231.

[0119] With the above configuration, the connecting part 1231 can be gripped by the gripping groove f, facilitating the movement of the connecting part 1231. This movement, in turn, causes the sealing part 1232 connected to the connecting part 1231 to seal the external connection hole b, or causes the sealing part 1232 connected to the connecting part 1231 to move out of the external connection hole b. The gripping groove f facilitates actual operation for the user.

[0120] In some embodiments, such as Figure 4 As shown, along the groove depth direction of the groove e, the gripping groove f penetrates the connecting part 1231, and the edge of the gripping groove f near the mating surface d has a notch g that communicates with the gripping groove f.

[0121] It is understandable that the notch g is formed on the side surface of the connection 1231 facing the mating surface d.

[0122] With the above configuration, when it is necessary to hold the connecting part 1231, the user's hand can enter the notch g through the grip groove f and thus hold the wall of the notch g. Since the wall of the notch g faces the mating surface d, the user's hand can hold the connecting part 1231 from opposite sides along the extension direction of the external hole b, so as to realize the grip of the connecting part 1231, which facilitates actual operation.

[0123] Of course, in other embodiments, only the gripping groove f can be provided, such that there is a certain distance between the end face of the part of the groove wall on the side of the gripping groove f away from the mating surface d and the peripheral wall of the groove e. This distance allows the user's hand to enter the gripping groove f and thus hold the inner wall of the gripping groove f to grip the connector.

[0124] In some embodiments, such as Figure 12 , Figure 13 As shown, the connecting part 1231 includes a support body 12311 and a connecting body 12312 connected together. A support space h is formed on the connecting body 12312. The support body 12311 is disposed in the support space h to support at least one of the connecting body 12312 and the sealing part 1232. The sealing part 1232 is connected to the connecting body 12312.

[0125] In other words, the above embodiments include three schemes: First, the support body 12311 is disposed within the support space h to support the connector 12312. Second, the support body 12311 is disposed within the support space h to support the sealing part 1232. Third, the support body 12311 is disposed within the support space h, simultaneously supporting both the connector 12312 and the sealing part 1232.

[0126] The supporting space h can be a cavity formed inside the connector 12312, in which case the support 12311 is disposed inside the connector 12312. Alternatively, the supporting space h can also be a groove-like structure formed on the connector 12312, in which case the support 12311 is embedded in the connector 12312. The specific choice can be made according to the needs.

[0127] In addition, the connector 12312 can be made of a plastic material with low hardness, while the support 12311 can be made of a metal material with high structural strength.

[0128] With the above configuration, the connecting part 1231 includes two parts: a support body 12311 and a connecting body 12312. The connecting body 12312 serves to connect the blocking part 1232, while the support body 12311 provides support for at least one of the connecting body 12312 and the blocking part 1232. This not only ensures the normal functioning of the connecting part 1231 and the blocking part 1232, but also guarantees the overall structural strength of the blocking structure 123.

[0129] In some embodiments, such as Figure 12 , Figure 13 As shown, the connecting body 12312 has an inwardly recessed support space h on the side near the sealing part 1232. The sealing part 1232 is connected to the bottom of the groove of the support space h. The support body 12311 has an avoidance hole j. The support body 12311 is sleeved on the sealing part 1232 through the avoidance hole j. The inner wall surface of the avoidance hole j abuts against the sealing part 1232 for support. The support body 12311 abuts against the peripheral wall surface of the support space h for support.

[0130] It is understood that in this embodiment, the support space h is a groove-shaped structure, and therefore the support space h has a groove bottom and a peripheral wall surface.

[0131] In some examples, the inner contour of the clearance hole j is consistent with the outer contour of the sealing part 1232. Thus, after the support body 12311 is fitted onto the sealing part 1232 through the clearance hole j, the inner wall surface of the clearance hole j and the sealing part 1232 can achieve a relatively tight abutment fit, thereby using the support body 12311 to provide stable support for the sealing part 1232.

[0132] In some examples, the peripheral wall of the support space h is consistent with the outer contour of the support body 12311. Thus, when the support body 12311 is placed in the support space h, the support body 12311 can fit and abut against the peripheral wall of the support space h, thereby providing stable support for the connector 12312.

[0133] In some examples, the charging base 120 also includes a mounting post 127 and a mounting hole 128. One of the mounting post 127 and the mounting hole 128 is located at the bottom of the clearance space, and the other is located on the side of the support body 12311 facing the bottom of the clearance space. The mounting hole 128 is engaged within the support body 12311, thereby connecting the support body 12311 and the connector 12312. This not only ensures a certain connection strength between the support body 12311 and the connector 12312, but also facilitates the disassembly of the support body 12311 and the connector 12312, improving the ease of assembly and disassembly. For ease of understanding, Figure 13 The diagram shows a case where the mounting hole 128 is located at the bottom of the groove in the support space h, and the mounting post 127 is located on the support body 12311.

[0134] The mounting holes 128 and mounting posts 127 can each be multiple, with the mounting posts 127 engaging with the corresponding mounting holes 128. For example, multiple mounting holes 128 and multiple mounting posts 127 are arranged around the sealing portion 1232, which improves the stability of the connection between the connector 12312 and the support 12311.

[0135] Furthermore, the mounting post 127 can be a regular columnar structure such as a cylinder, a frustum, or a square prism. Correspondingly, the mounting hole 128 can be a regular shape such as a circular hole or a directional hole. Alternatively, the mounting post 127 can also be an irregular columnar structure, and correspondingly, the mounting hole 128 can also be an irregular hole structure.

[0136] With the above configuration, by opening a clearance hole j on the support body 12311, the support body 12311 can be fitted onto the sealing part 1232 through the clearance hole j, so that the support body 12311 provides support for the sealing part 1232. At the same time, the connecting body 12312 provides support for the peripheral wall surface of the support space h, thereby achieving support for the connecting body 12312. In this way, the support body 12311 provides support for both the connecting body 12312 and the sealing part 1232.

[0137] 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.
