Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0033] The charging connector can be used to connect the breast pump to an external power source. Since there may be some water stains or milk stains on the breast pump, when the breast pump is being charged, if the stains enter the charging device, it can easily cause the charging device to malfunction and affect its normal use.

[0034] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 This application provides an example of a charging device, which includes a charging terminal 30, a mounting assembly 10, and a sealing assembly 20. The mounting assembly 10 has a first surface 113 and is at least partially hollow to form a mounting groove 13. One end of the mounting groove 13 is closed, and the other end extends through to the first surface 113. The sealing assembly 20 is connected to the mounting assembly 10 and is at least partially disposed near the first surface 113. The sealing assembly 20 and the inner wall of the mounting groove 13 enclose an inner cavity 16. The sealing assembly 20 has an insertion hole 221 that communicates with the inner cavity 16 and the external environment of the mounting assembly 10. One end of the charging terminal 30 is inserted into the inner cavity 16, and the other end passes through the insertion hole 221 and protrudes from the first surface 113. The charging terminal 30 is sealed to the sealing assembly 20.

[0035] The charging terminal 30 can be used to connect to a power source so that it can act as a conductor to charge the electronic device. In this example, the charging terminal 30 can be a pogopin. The charging terminal 30 has a first end 32 and a second end 33 disposed opposite to each other, wherein the first end 32 and the second end 33 can be two ends of the charging terminal 30 along its length.

[0036] The mounting component 10 can serve as the main structure of the charging device. The mounting component 10 can be a standalone structure or integrated into the breast pump. The mounting component 10 has a first surface 113, which can be one end face of the mounting component 10. For ease of description, this example uses the upper surface of the mounting component 10 as an example. When the charging device is installed on the breast pump, the first surface 113 can be on the same surface as the outer surface of the breast pump. Optionally, the first surface 113 can also be a surface recessed into the outer surface of the breast pump. Optionally, a through hole can be formed in the breast pump. The first surface 113 can also be attached to the inner surface of the breast pump, with only the charging terminal 30 exposed at the through hole in the breast pump. The mounting assembly 10 is at least partially hollow to form a mounting groove 13. The mounting groove 13 can be a recessed groove formed on one surface of the mounting assembly 10. The mounting groove 13 can be used to accommodate the wires to be connected to the charging terminal 30. One end of the mounting groove 13 is closed, and the other end extends through to the first surface 113, so that the mounting groove 13 forms a recessed groove communicating with the first surface 113. The inner wall of the mounting groove 13 includes a bottom wall 15 and side walls surrounding the bottom wall 15. The bottom wall 15 faces the first surface 113. Taking the first surface 113 as an example where it is located on the upper surface of the mounting assembly 10, the first end 32 of the charging terminal 30 can be inserted into the mounting groove 13 from top to bottom. The second end 33 of the charging terminal 30 extends out of the mounting groove 13 so that the second end 33 of the charging terminal 30 can be electrically connected to an electronic device outside the charging device.

[0037] The sealing component 20 is connected to the mounting component 10 so that the sealing component 20 can be fixed to the mounting component 10. In this example, the sealing component 20 is at least partially disposed near the first surface 113, and the mounting groove 13 forms an opening 14 at one end near the first surface 113, so that the sealing component 20 is at least partially encapsulated on one side of the opening 14 of the mounting groove 13, so that the sealing component 20 can form an inner cavity 16 between itself and the inner wall surface of the mounting groove 13. The sealing component 20 has a socket 221 that communicates with the inner cavity 16 and the external environment of the mounting component 10. The socket 221 is used to form a space for mounting the charging terminal 30. Taking the first surface 113 facing upward as an example, the socket 221 can be a through hole that penetrates the thickness direction of the sealing component 20.

[0038] The charging terminal 30 is disposed through the socket 221 so that the socket 221 can limit the movement of the charging terminal 30 in the radial direction, thereby reducing problems such as the charging terminal 30 collapsing. One end of the charging terminal 30 protrudes from the first surface 113 so that the charging terminal 30 can be connected to an external device, and the other end of the charging terminal 30 is inserted into the inner cavity 16 so that the charging terminal 30 can be electrically connected to the circuit of the inner cavity 16.

[0039] The sealing connection between the charging terminal 30 and the sealing component 20 refers to the mutual sealing of the connection points between the sealing component 20 and the charging terminal 30. In this example, the mutual sealing can reduce the gap between the contact points of the charging terminal 30 and the sealing component 20, for example, by making the contact points of the sealing component 20 and the charging terminal 30 an elastic material so that the sealing component 20 can seal against the outer peripheral surface of the charging terminal 30; or, the mutual sealing can extend the gap between the contact points of the charging terminal 30 and the sealing component 20, for example, by making the gap between the contact points of the charging terminal 30 and the sealing component 20 a zigzag line, a curve, or a combination thereof, so as to reduce the entry of water into the inner cavity 16 by extending the flow path of water at the contact points of the charging terminal 30 and the sealing component 20. In this example, the sealing connection between the sealing component 20 and the charging terminal 30 can reduce the entry of dirt into the inner cavity 16, reduce the problem of dirt accumulation in the inner cavity 16 causing restricted movement of the charging terminal 30, and thus reduce charging device malfunctions. It can also reduce the problem of short circuits by reducing water ingress into the inner cavity 16.

[0040] In some examples, the sealing component 20 is made of an elastic material. An elastic material is one that exhibits elastic deformation under stress, such as silicone or rubber. The sealing component 20 can elastically deform when subjected to external force. When the charging terminal 30 is subjected to external pressure, it moves towards the bottom wall 15 along with the sealing component 20, and the sealing component 20 simultaneously undergoes elastic deformation, thus maintaining a good seal between the sealing component 20 and the charging terminal 30. Due to the elastic force of the sealing component 20, when the external force acting on the charging terminal 30 disappears, the sealing component 20 exerts a force on the charging terminal 30 to move it away from the bottom wall 15, thereby causing the charging terminal 30 to reset and reducing the possibility of the charging terminal 30 getting stuck. With the elastic limit of the sealing component 20, the possibility of the charging terminal 30 becoming skewed when the charging device is improperly placed can be reduced, allowing for more precise extension and retraction of the charging terminal 30 along a preset trajectory and improving the directionality of the charging terminal 30's movement.

[0041] Please refer to the following: Figure 2 , Figure 3 as well as Figure 5 In some examples, the sealing assembly 20 is provided with a first sealing part 2211, and the outer peripheral surface of the charging terminal 30 is provided with a second sealing part 31. One of the first sealing part 2211 and the second sealing part 31 is a protrusion and the other is a groove. The protrusion is embedded in the groove to form a sealed connection.

[0042] The sealing assembly 20 is sealed to the charging terminal 30 to seal the contact area between the sealing assembly 20 and the charging terminal 30. The first sealing part 2211 is provided on the sealing assembly 20. The first sealing part 2211 can be separately provided and connected to the sealing assembly 20, or the first sealing part 2211 can be integrally provided with the sealing assembly 20.

[0043] The second sealing part 31 is disposed on the outer peripheral surface of the charging terminal 30. The second sealing part 31 cooperates with the first sealing part 2211 to form a sealed connection. One of the first sealing part 2211 and the second sealing part 31 is a protrusion, and the other is a groove, with the protrusion embedded in the groove. In this example, the first sealing part 2211 is a protrusion and the second sealing part 31 is a groove. When the first sealing part 2211 is embedded in the second sealing part 31, it can prevent impurities from flowing directly into the inner cavity 16 through the gap between the charging terminal 30 and the second sealing body 22. Furthermore, when water enters the gap between the charging terminal 30 and the sealing assembly 20, the flow rate of the water can be slowed down by extending the flow path of the water in the gap and increasing the complexity of the gap, thereby reducing the amount of water entering the inner cavity 16.

[0044] In some examples, the charging terminal 30 has a first end 32 and a second end 33 disposed opposite to each other. The first end 32 of the charging terminal 30 is inserted into the inner cavity 16, and the second end 33 of the charging terminal 30 passes through the socket 221 and protrudes from the first surface 113. The second sealing part 31 is disposed closer to the second end 33 than the first end 32. The first end 32 and the second end 33 are the two ends in the length direction of the charging terminal 30. The first end 32 is disposed in the inner cavity 16 and can be used to connect wires. The second end 33 protrudes from the side of the sealing assembly 20 away from the bottom wall 15 so that the second end 33 can be used to connect external electronic components.

[0045] In this example, the second sealing part 31 is positioned closer to the second end 33 than the first end 32, so that the second end 33 of the charging terminal 30 protrudes sufficiently from the outside of the sealing assembly 20, thereby minimizing the exposure of the charging terminal 30 on the outside of the sealing assembly 20 and reducing the amount of dirt adhering to the charging terminal 30.

[0046] In some examples, the charging device also includes a reset member 40, which is disposed in the inner cavity 16. One end of the reset member 40 is connected to the inner wall of the mounting groove 13, and the other end is connected to the charging terminal 30. The reset member 40 is used to generate a force on the charging terminal 30 to move it outward from the mounting groove 13.

[0047] A reset member 40 is disposed in the inner cavity 16. One end of the reset member 40 can be connected to the bottom wall 15, and the other end can be connected to the first end 32 of the charging terminal 30, so that the reset member 40 can act on the charging terminal 30 and generate an elastic force on the charging terminal 30. The reset member 40 is used to generate a force on the charging terminal 30 to move away from the bottom wall 15. When the charging terminal 30 is subjected to external pressure, the charging terminal 30 moves towards the bottom wall 15 and presses the reset member 40, causing the reset member 40 to deform. At this time, the reset member 40 generates a force on the charging terminal 30 to move away from the bottom wall 15. When the external pressure force on the charging terminal 30 disappears, the charging terminal 30 can return to its original position under the action of the reset member 40. In this example, the charging terminal 30 can be fixedly connected to the reset member 40, or it can abut against the reset member 40. The reset member 40 can be fixedly connected to the bottom wall 15.

[0048] In some examples, the reset member 40 is a spring; the mounting assembly 10 has a guide hole 1211 that communicates with the mounting groove 13, and the reset member 40 is installed in the guide hole 1211. The charging terminal 30 passes through the guide hole 1211 at least partially and is connected to the reset member 40. When the reset member 40 is pressed by the charging terminal 30, it can exert a force on the charging terminal 30 to move away from the bottom wall 15. The number and position of the guide holes 1211 correspond to the number and position of the reset members 40. The reset member 40 is at least partially installed in the guide holes 1211 so that when the reset member 40 undergoes elastic deformation, the reset member 40 is restricted by the guide holes 1211, so that the reset member 40 can only move along the extension direction of the guide holes 1211. The reset member 40 is not prone to collapsing, thereby improving the stability of the deformation direction of the reset member 40 and thus improving the stability of the movement trajectory of the charging terminal 30. In some examples, when the reset member 40 is in its natural state, the first end 32 of the charging terminal 30 is at least partially embedded in the guide hole 1211 so that the first end 32 of the charging terminal 30 can move along the extension direction of the guide hole 1211.

[0049] In some examples, the mounting component 10 is provided with a protrusion 121, which is connected to the bottom wall 15 and protrudes towards the first surface 113. A guide hole 1211 is formed on the protrusion 121. The protrusion 121 is located in the inner cavity 16. The protrusion 121 can be provided on the bottom wall 15, and can be integrally formed with the part of the bottom wall 15, or it can be separately formed and connected to each other. The protrusion 121 can be used to form a thickened area in the inner cavity 16 to facilitate the formation of the guide hole 1211.

[0050] In some examples, the sealing component 20 is made of an elastic material; the elastic force of the sealing component 20 is no greater than the elastic force of the reset component 40. Since the elastic force of the sealing component 20 is no greater than the elastic force of the reset component 40, during the movement of the charging terminal 30 towards the bottom wall 15, the reset component 40 can exert an elastic force on the charging terminal 30, reducing jamming and abnormal positioning of the charging terminal 30 due to excessive movement, thus allowing the charging terminal 30 to reset normally.

[0051] Please refer to the following: Figure 2 , Figure 3 , Figure 4 as well as Figure 6 In some examples, a bottom wall 15 is formed at the closed end of the mounting groove 13; the sealing assembly 20 extends at least partially from the first surface 113 toward the bottom wall 15. The portion of the sealing assembly 20 extending away from the first surface 113 can be used to form a sealing structure inside the mounting groove 13, reducing the possibility of impurities flowing along the inner wall of the mounting groove 13 toward the inner cavity 16. When installing the sealing assembly 20, the portion extending toward the bottom wall 15 can be connected and fixed to the mounting assembly 10, thereby increasing the connection area between the sealing assembly 20 and the mounting assembly 10.

[0052] In some examples, the sealing assembly 20 may include a first sealing body 21 and a second sealing body 22. The first sealing body 21 is arranged in a ring and is arranged around the inner wall of the mounting groove 13. The second sealing body 22 is disposed close to the first surface 113, and the outer periphery of the second sealing body 22 is connected to the first sealing body 21. The first sealing body 21, the second sealing body 22 and the bottom wall 15 of the mounting groove 13 enclose an inner cavity 16. The second sealing body 22 has an insertion hole 221, and the charging terminal 30 is sealed to the second sealing body 22.

[0053] The first sealing body 21 is used to connect the mounting assembly 10. The first sealing body 21 is disposed on the inner wall surface of the mounting groove 13 so that the first sealing body 21 can be limited to a preset position on the mounting assembly 10. The first sealing body 21 is arranged in a ring shape, which means that the shape of the first sealing body 21 is substantially the same as the inner surface of the mounting groove 13, so that the first sealing body 21 can be mounted on the mounting assembly 10 in an inner and outer ring.

[0054] The second sealing body 22 is used to support and fix the charging terminal 30. The outer periphery of the second sealing body 22 is connected to the first sealing body 21, meaning that the outer periphery of the second sealing body 22 is connected to the first sealing body 21. In this example, the first sealing body 21 and the second sealing body 22 can be separately arranged and connected to each other, or the first sealing body 21 can be integrally arranged with the second sealing body 22. The second sealing body 22 has a socket 221 for installing the charging terminal 30. The charging terminal 30 is sealed to the second sealing body 22 so that the second sealing body 22 can reduce the entry of dirt into the inner cavity 16 along the gap between the socket 221 and the charging terminal 30. In this example, the shape of the second sealing body 22 is adapted to the shape of the first sealing body 21 so that the second sealing body 22 can be arranged facing the bottom wall 15. The second sealing body 22, the first sealing body 21, and the bottom wall 15 enclose the inner cavity 16.

[0055] Along the bottom wall 15 toward the opening 14, the depth of the mounting groove 13 can be greater than the height of the first sealing body 21. In this example, one end of the first sealing body 21 can extend to the bottom wall 15, and the second sealing body 22 can be at least partially located within the mounting groove 13. The end of the charging terminal 30 away from the bottom wall 15 protrudes outward from the mounting assembly 10. By combining the first sealing body 21 and the second sealing body 22, the first sealing body 21 can serve as an intermediate connector between the second sealing body 22 and the mounting assembly 10, thereby fixing the sealing assembly 20 and reducing the possibility of the sealing assembly 20 detaching from the mounting assembly 10.

[0056] In some examples, the mounting assembly 10 is provided with a protrusion 121, which is connected to the bottom wall 15 and protrudes towards the first surface 113. The sealing assembly 20 is at least partially sealingly connected between the outer peripheral surface of the protrusion 121 and the side wall of the mounting groove 13. The protrusion 121 is located in the inner cavity 16. The protrusion 121 can be provided on the bottom wall 15, and can be integrally provided with the part of the bottom wall 15, or it can be separately provided and interconnected. The sealing assembly 20 is at least partially sealingly connected between the outer peripheral surface of the protrusion 121 and the side wall of the mounting groove 13, so that the sealing assembly 20 can be used to seal the gap between the protrusion 121 and the inner wall surface of the mounting groove 13, thereby extending the sealing area of ​​the sealing assembly 20. Optionally, the sealing assembly 20 includes a first sealing body 21 and a second sealing body 22 in any of the above examples. The first sealing body 21 is at least partially provided between the outer peripheral surface of the protrusion 121 and the inner wall surface of the mounting groove 13. The protrusion 121 can be used to limit the first sealing body 21 so that the first sealing body 21 is clamped between the protrusion 121 and the inner wall surface of the mounting groove 13. The first sealing body 21 can also be used to seal the gap between the protrusion 121 and the inner wall surface of the mounting groove 13.

[0057] Please see Figure 7 , Figure 8 as well as Figure 9 In some examples, the reset element 40 is a metal spring. The metal spring can be formed by bending a metal sheet. Because the metal spring has high directionality during deformation, it is relatively more stable during movement. When installing the metal spring, fewer guiding structures are needed around it, and the metal spring has high deformation stability. Therefore, the area around the metal spring can be left empty. When dirt enters the inner cavity 16, the large accommodating space around the metal spring reduces the accumulation of dirt around the first end 32 of the charging terminal 30, thereby reducing jamming of the charging terminal 30. Optionally, the sealing component 20 can be made of an elastic material or a hard plastic with high hardness.

[0058] In some examples, the mounting assembly 10 has a drain outlet (not shown) that connects the inner cavity 16 to the external environment of the charging device. The drain outlet can be located on the mounting assembly 10 near the bottom wall 15, and is used to drain water from the inner cavity 16 to the outside of the charging device. When the charging device is mounted on a breast pump, the drain outlet can be connected to any location between the inner cavity 16 and the outside of the breast pump; alternatively, the drain outlet can also be connected to a drainage channel on the breast pump.

[0059] In some examples, the mounting assembly 10 includes a mounting base 11 and a mounting bracket 12. The mounting base 11 has a mounting hole 111 with an inner end 111a and an outer end 111b disposed opposite to each other. The sealing assembly 20 is at least partially connected to the mounting base 11. The mounting bracket 12 is connected to the mounting base 11 and is disposed at the inner end 111a of the mounting hole 111. The mounting bracket 12 and the inner wall surface of the mounting hole 111 enclose a mounting groove 13. A first surface 113 is formed on the side of the mounting base 11 opposite to the mounting bracket 12.

[0060] The mounting base 11 can be used to connect to a breast pump. The mounting base 11 has a mounting hole 111, which can be a through hole that passes through the mounting base 11. The mounting hole 111 has an inner end 111a and an outer end 111b that are disposed opposite to each other, and the outer end 111b can communicate with the outside of the charging device.

[0061] The mounting bracket 12 is connected to the mounting base 11 and is used to assemble with the mounting base 11 on one side of the inner end 111a of the mounting hole 111. The mounting bracket 12 and the inner wall surface of the mounting hole 111 form a mounting groove 13, wherein the mounting base 11 has a first surface 113 on the side opposite to the mounting bracket 12. Optionally, the mounting bracket 12 can be connected and fixed to the mounting base 11 by screw connection, snap-fit, pin connection or other means.

[0062] The sealing component 20 can be connected to the mounting base 11. Optionally, the sealing component 20 can be annularly disposed on the inner wall surface of the mounting hole 111 so that the sealing component 20 can be installed on the mounting component 10. The sealing component 20 can be connected to the inner wall surface of the mounting hole 111 by bonding, pressing, embedding or other connection methods. Optionally, the sealing component 20 includes a first sealing body 21 and a second sealing body 22 in any of the above examples, wherein the first sealing body 21 is disposed within the mounting hole 111, and the first sealing body 21 and the mounting base 11 are disposed in an inner and outer manner.

[0063] In this example, the mounting base 11 and the mounting bracket 12 are combined to form the mounting assembly 10. On the one hand, this facilitates the subsequent assembly of the charging terminal 30 and reduces the assembly difficulty of the mounting assembly 10. On the other hand, it facilitates the molding of the mounting assembly 10 and reduces material waste.

[0064] Please refer to the following: Figure 4 , Figure 10 , Figure 11 and Figure 12 In some examples, the mounting base 11 has a second surface 112 formed on the side opposite to the first surface 113, the second surface 112 connecting the inner wall of the mounting hole 111 and the outside of the mounting base 11; the sealing assembly 20 extends away from the first surface 113 and is disposed between the second surface 112 and the mounting bracket 12.

[0065] Mounting base 11 has a second surface 112 facing mounting bracket 12. The second surface 112 is opposite to and spaced from bottom wall 15. The second surface 112 is opposite to first surface 113. The second surface 112 connects the inner wall of mounting hole 111 and the outer side of mounting base 11, meaning that the second surface 112 extends from the outer side of mounting base 11 to the inner wall of mounting hole 111. The sealing assembly 20 extends away from the first surface 113 and is disposed between the second surface 112 and mounting bracket 12, meaning that the sealing assembly 20 fills the gap between the second surface 112 and mounting bracket 12 to seal the gap between mounting base 11 and mounting bracket 12. Optionally, the sealing assembly 20 includes a first sealing body 21 and a second sealing body 22 in any of the above examples. The sealing assembly 20 also includes a third sealing body 23 connected to the end of the first sealing body 21 away from the second sealing body 22, and the third sealing body 23 is used to fill the gap between the second surface 112 and mounting bracket 12. The third sealing body 23 can be made of an elastic material, which can elastically seal the gap between the second surface 112 and the mounting bracket 12. The third sealing body 23 is annular, and has an inner ring edge and an outer ring edge. The inner ring edge of the third sealing body 23 can be connected to the first sealing body 21, and the outer ring edge of the third sealing body 23 extends away from the first sealing body 21. The shape of the third sealing body 23 is consistent with the shape of the gap between the second surface 112 and the mounting bracket 12.

[0066] In some examples, a sealing flange 25 is provided between the third sealing body 23 and the second surface 112. The sealing flange 25 may be a convex ring provided on the third sealing body 23. The sealing flange 25 is used to seal the gap between the third sealing body 23 and the second surface 112.

[0067] In some examples, the mounting assembly 10 also includes a mounting base 17, which can be connected to the mounting assembly 10 by screws, clips, pins or other components. The mounting base 17 is located on the side of the mounting bracket 12 opposite to the mounting base 11, and can be used to connect devices such as the main unit of a breast pump.

[0068] In some examples, the mounting base 11 has an outer annular surface connected to the end of the second surface 112 away from the mounting hole 111; the mounting bracket 12 is provided with a flange 122 on the side facing the mounting base 11, the flange 122 being fitted around the periphery of the outer annular surface; the sealing assembly 20 extends further between the outer annular surface and the flange 122 at the end away from the first surface 113.

[0069] The flange 122 is a protruding structure that protrudes from the mounting bracket 12 on the side facing the mounting base 11. The flange 122 is arranged around the outer ring surface of the mounting base 11, and there is a gap between the flange 122 and the outer ring surface of the mounting base 11.

[0070] The end of the sealing assembly 20 away from the first surface 113 extends between the outer annular surface and the flange 122, so that the sealing assembly 20 can seal the gap between the outer annular surface and the flange 122. Optionally, the sealing assembly 20 may include a first sealing body 21, a second sealing body 22, and a third sealing body 23 in any of the above examples. The sealing assembly 20 also includes a fourth sealing body 24, which is connected to the outer annular edge of the third sealing body 23. The fourth sealing body 24 is disposed within the gap between the flange 122 and the outer annular surface of the mounting base 11, so that the fourth sealing body 24 can seal the gap between the flange 122 and the outer annular surface of the mounting base 11. Optionally, the fourth sealing body 24 may be inner and outer sleeved with the first sealing body 21, wherein the shape and size of the fourth sealing body 24 correspond to the shape and size of the flange 122, so that the fourth sealing body 24 can fill the gap between the flange 122 and the outer annular surface of the mounting base 11. The fourth sealing body 24 may be made of an elastic material to seal by elastic compression. Optionally, the fourth sealing body 24 can be integrally formed with the third sealing body 23 for ease of processing, and both the fourth sealing body 24 and the third sealing body 23 can be made of elastic material.

[0071] Please see Figure 2 , Figure 3 , Figure 11 as well as Figure 12 In some examples, the sealing component 20 has a pleat 222 at one end near the first surface 113, and the pleat 222 surrounds the periphery of the socket 221. The pleat 222 can be a bending area formed by a partial bending of the sealing component 20. By providing the pleat 222, the deformation capability of the end of the sealing component 20 near the first surface 113 can be increased, thereby increasing the range of movement of the charging terminal 30 and reducing the possibility of the charging terminal 30 detaching from the sealing component 20. The pleat 222 surrounding the periphery of the socket 221 means that the pleat 222 can be an annular structure surrounding the periphery of the socket 221. In the examples of this application, the pleat 222 can be as follows: Figure 2 , Figure 3 The sealing assembly 20 is partially bent at one end near the first surface 113, forming a bent structure. In a cross-section parallel to the axial direction of the charging terminal 30, the wrinkles 222 are bent; it can also be as follows: Figure 11 , Figure 12 The sealing assembly 20 is formed by multiple bends at one end near the first surface 113, creating a complex curved surface structure, such as... Figure 12In the cross section parallel to the axial direction of the charging terminal 30, the wrinkles 222 have a wavy structure.

[0072] In some examples, the sealing assembly 20 is provided with multiple sockets 221 and multiple charging terminals 30. The number of charging terminals 30 corresponds one-to-one with the number of sockets 221. The pleats 222 surround the periphery of the area where the multiple sockets 221 are located, so that the multiple sockets 221 are located inside the annular area formed by the pleats 222. This allows the charging terminals 30 in the multiple sockets 221 to have the same or similar range of movement, reducing the possibility that some of the charging terminals 30 may fall off due to uneven force.

[0073] In some examples, the charging device also includes a magnet 50 connected to the mounting assembly 10, with the first surface 113 and at least a portion of the magnet 50 located on the same side of the mounting assembly 10.

[0074] The magnetic body 50 can be attracted to an external magnetically oriented structure, allowing the charging device to be positioned relative to the external structure. The magnetic body 50 is connected to the mounting assembly 10, meaning it can be mounted on the outer surface of the mounting assembly 10 or on the inner side of the mounting assembly 10. The first surface 113 and at least a portion of the magnetic body 50 are located on the same side of the mounting assembly 10. The first surface 113 can serve as a working surface for the charging device to adapt to the external structure, and the magnetic body 50 is used to magnetically attract the external structure.

[0075] In some examples, a magnetic body 50 is mounted on the mounting groove 13, and a through hole is formed on the magnetic body 50. The position of the through hole corresponds to the position of the insertion hole 221, so that the charging terminal 30 can pass through the insertion hole 221 and the through hole on the magnetic body 50 in sequence and extend out of the outer side of the first surface 113. In this example, the magnetic body 50 can be wrapped around the outer periphery of the charging terminal 30 to guide the charging terminal 30, further improving the directionality of the movement of the charging terminal 30 and reducing the possibility of the charging terminal 30 falling over.

[0076] In some examples, the mounting groove 13 is closed at one end near the first surface 113, and a through hole 18 is formed on the first surface 113, connecting the mounting groove 13. The position of the through hole 18 corresponds to the position of the socket 221, so that the charging terminal 30 can pass through the socket 221 and the through hole 18 in sequence and extend out of the outside of the first surface 113. In this example, the mounting assembly 10 can surround the outer periphery of the charging terminal 30, and the inner wall of the through hole 18 can limit the charging terminal 30 to guide it, further improving the directionality of the movement of the charging terminal 30 and reducing the possibility of the charging terminal 30 falling over.

[0077] In some examples, the mounting assembly 10 includes a mounting base 11 and a mounting bracket 12. The mounting base 11 has a mounting hole 111 with an inner end 111a and an outer end 111b disposed opposite to each other. The sealing assembly 20 is at least partially connected to the mounting base 11. The mounting bracket 12 is connected to the mounting base 11 and is disposed at the inner end 111a of the mounting hole 111. A first surface 113 is formed on the side of the mounting base 11 away from the mounting bracket 12. The end of the magnetic body 50 away from the first surface 113 is connected between the mounting base 11 and the mounting bracket 12.

[0078] In this example, the mounting base 11 and mounting bracket 12 can have the same structure as in the examples above, and will not be repeated. The end of the magnetic body 50 away from the first surface 113 is connected between the mounting base 11 and the mounting bracket 12, so that the end of the magnetic body 50 away from the first surface 113 can be fixed within the gap between the mounting base 11 and the mounting bracket 12, thereby limiting and fixing the magnetic body 50. In some examples, the end of the magnetic body 50 away from the first surface 113 can be bent, so that one end of the magnetic body 50 can be inserted between the mounting bracket 12 and the second surface 112. The second surface 112 can limit the magnetic body 50, and the third sealing body 23 can seal the gap between the magnetic body 50 and the mounting bracket 12. In some examples, the end of the magnetic body 50 away from the bottom wall 15 can be bent to increase the surface area of ​​the magnetic body 50, thereby enhancing the magnetic attraction of the magnetic body 50.

[0079] Please see Figure 13 This application also provides an example of a breast pump, which includes a main unit 60. The main unit 60 includes a charging device as described in any of the above examples. The charging terminal 30 of the charging device is used to connect to a power source to charge the main unit 60. The main unit 60 can be the main body structure of the breast pump, or it can be the charging base of the breast pump. The charging device can be used to directly charge the breast pump, or it can charge the breast pump through the charging base, or it can charge the charging base and then charge the main body of the breast pump through the charging base.
