[0036] Example 1:
[0037] Please see Figure 1-5 and Figure 14The present invention discloses a breast pump with a heating component connection structure, comprising a breast pump body 1, wherein the breast pump body 1 includes a bra 2 that contacts the breast and a main unit assembly 3. The bra 2 is provided with a heating component 21, which is electrically connected to the main unit assembly 3 through a connecting terminal 27. The main unit assembly 3 is provided with a docking hole 31 for the connecting terminal 27 to be inserted and connected, so that the connecting terminal 27 is fixed in the docking hole 31. The connecting terminal 27 and the docking hole 31 are electrically connected through surface contact.
[0038] This invention enables electrical connection between the connecting terminal 27 and the mating hole 31 through surface contact, effectively solving the problem of small conductive area and limited current carrying capacity caused by point contact in the power supply structure of the magnetic probe in the prior art. This avoids unstable power transmission caused by overheating and oxidation of the contact point. In addition, by inserting the connecting terminal 27 into the mating hole 31, the stability of the connection between the connecting terminal 27 and the mating hole 31 is enhanced, effectively solving the problem of unstable connection caused by magnetic force attenuation and mechanical vibration in the power supply structure of the magnetic probe, which leads to unstable power supply.
[0039] Specifically, traditional magnetic probe power supply structures use point contact for power transmission, resulting in a limited conductive area, restricting current carrying capacity, and easily leading to overheating and oxidation at the contact points, thus causing unstable power transmission. This invention, however, achieves electrical connection between the connecting terminal 27 and the mating hole 31 through surface contact, fundamentally solving the problem of small conductive area and limited current carrying capacity caused by point contact in existing magnetic probe power supply structures. This design, using surface contact between the connecting terminal 27 and the mating hole 31, not only increases the effective area of the electrical connection and improves current transmission capacity, but also effectively avoids power transmission instability caused by overheating and oxidation at the contact points, ensuring high efficiency and stability in the power transmission process. Furthermore, traditional magnetic probes... Another drawback of the probe power supply structure is that the magnetic attraction effect gradually weakens during long-term use. Combined with mechanical vibrations during daily operation, this can lead to loosening of the contact, affecting the stability of the heating temperature and the overall user experience. This invention, by setting the connecting terminal 27 to be inserted into the mating hole 31, further enhances the stability and reliability of the connection between the connecting terminal 27 and the mating hole 31, avoiding the problem of poor contact in the power supply structure due to mechanical vibration. Furthermore, by inserting the connecting terminal 27 into the mating hole 31, the user's operation process is simplified, making it more intuitive and convenient to connect the connecting terminal 27 and the mating hole 31. At the same time, it also reduces the possibility of loosening of the connection due to external forces, ensuring the continuity and stability of the power supply.
[0040] Furthermore, such as Figure 1-5 and Figure 14 The breast pump shown has a heating component connection structure, wherein the connection terminal 27 is provided with a first power supply terminal 221 and a mating terminal 222, the mating hole 31 is provided with a mating hole 312 for the mating terminal 222 to be inserted, and a second power supply terminal 311 that is electrically connected to the first power supply terminal 221 through surface contact, the second power supply terminal 311 is located inside the mating hole 312, and the mating terminal 222 and the mating hole 312 are connected by a tight fit.
[0041] This invention achieves electrical connection by providing a first power supply end 221 on the connecting terminal 27 and a second power supply end 311 on the mating hole 31, with the surface of the first power supply end 221 contacting and engaging with the surface of the second power supply end 311. This arrangement not only increases the conductive area and improves the current carrying capacity but also ensures the stability and reliability of power transmission, avoiding the power transmission instability problem caused by the point contact power supply structure of the traditional magnetic probe. Furthermore, this invention provides a mating end 222 around the first power supply end 221 on the connecting terminal 27 and a mating hole 312 for inserting the mating end 222 on the mating hole 31, with the mating end 222 and the mating hole 312 tightly connected, thereby achieving a stable connection between the mating end 222 and the mating hole 312. This arrangement effectively enhances the connection stability between the connecting terminal 27 and the mating hole 31, effectively avoiding the problem of unstable electrical connection caused by loosening of the connection between the connecting terminal 27 and the mating hole 31 due to external factors.
[0042] Furthermore, such as Figure 1-5 and Figure 14 The breast pump shown has a heating component connection structure, wherein the main unit component 3 is further provided with a mounting end face 32 for mounting a bra 2, and the docking hole 31 is provided on the side near the mounting end face 32, so that the connecting terminal 27 is inserted into the docking hole 31 in the direction of the mounting end face 32 or in the direction of the periphery of the mounting end face 32.
[0043] This invention, by setting the mating hole 31 on the mounting end face 32, allows the connecting terminal 27 to be directly inserted into the mating hole 31 towards the mounting end face 32 when the bra 2 is installed on the mounting end face 32. This setting not only simplifies the installation process of the bra 2 and the main unit 3, making it easier for users to quickly complete the connection, but also improves the tightness and stability of the connection between the bra 2 and the main unit 3. Furthermore, in some embodiments, the mating hole 31 can also be set on the side adjacent to the mounting end face 32, that is, on the side of the mounting end face 32, so that the connecting terminal 27 can be inserted into the mating hole 31 from the side of the mounting end face 32. This not only makes it easier for users to observe the insertion port, but also makes it easier for users to perform the docking operation.
[0044] Furthermore, such as Figure 1-5 and Figure 14 The breast pump shown has a heating component connection structure, wherein the bra 2 is further provided with a first flexible part 24 and a second flexible part 25 connected to the first flexible part 24, the heating component 21 is located between the first flexible part 24 and the second flexible part 25, the connecting terminal 27 and the heating component 21 are connected by welding, and the first flexible part 24, the second flexible part 25, the heating component 21 and the connecting terminal 27 are integrally formed by overmolding.
[0045] This invention achieves a tight structural integration by incorporating a first flexible part 24 and a second flexible part 25 within the bra 2, placing the heating component 21 between them, and simultaneously welding the connecting terminal 27 to the heating component 21. Furthermore, the first flexible part 24, the second flexible part 25, the heating component 21, and the connecting terminal 27 are integrally molded using a rubber coating. This design not only effectively improves the overall sealing performance of the bra 2, ensuring that moisture and other impurities cannot enter and damage the heating component 21, but also prevents potential leakage risks, enhancing safety during use. Moreover, the integrally molded structure of the bra 2 simplifies the assembly process, reduces the possibility of production errors, and makes the entire bra 2 more compact and robust, thereby enhancing overall stability.
[0046] Furthermore, such as Figure 1-5 and Figure 14 The breast pump shown has a heating component connection structure, wherein the cross-section of the mating end 222 and the cross-section of the mating hole 312 are both rectangular or elliptical.
[0047] This invention effectively enhances the connection stability between the connecting terminal 27 and the mating hole 31 by setting the cross-sections of both the mating end 222 and the mating hole 312 to rectangular or elliptical shapes. This design not only allows for more precise alignment of the mating end 222 and the mating hole 312 during connection but also provides a larger contact area, thereby improving the stability and firmness of the connection. Furthermore, this design also allows for a tight fit between the mating end 222 and the mating hole 312, effectively preventing loosening or displacement that may occur due to external forces. In this embodiment, both the cross-sections of the mating end 222 and the mating hole 312 are rectangular. In other embodiments, both the cross-sections of the mating end 222 and the mating hole 312 are elliptical.
[0048] Furthermore, such as Figure 1-5 and Figure 14The illustration shows a breast pump with a heating component connection structure, wherein the heating component 21 is arranged in a ring shape inside the bra 2.
[0049] This invention effectively improves the uniformity and coverage of heating of the bra 2 by arranging the heating component 21 in a ring shape inside the bra 2, thereby better exerting the heat therapy effect, promoting smooth mammary glands and improving lactation efficiency; furthermore, this arrangement can also ensure the uniformity of heating of the breast area and reduce the situation of local overheating or insufficient heating.
[0050] Furthermore, such as Figure 1-5 and Figure 14 The breast pump shown has a heating component connection structure, wherein the first power supply end 221 is disposed on the mating end 222, the first power supply end 221 is cylindrical, the second power supply end 311 is a hole-shaped arrangement adapted to the shape of the first power supply end 221, and the first power supply end 221 is provided with multiple.
[0051] This invention, by setting multiple cylindrical first power supply terminals 221 and configuring the second power supply terminal 311 as a hole-shaped configuration adapted to the shape of the first power supply terminal 221, not only increases the conductive area of the first power supply terminal 221 and the second power supply terminal 311, effectively solving the problems of small conductive area and unstable power transmission caused by the traditional magnetic probe point contact method, thereby improving the current carrying capacity, but also further ensuring the stability and reliability of the electrical connection; furthermore, the cylindrical and hole-shaped configuration makes the insertion and removal operation between the connection terminal 27 and the mating hole 31 smoother, and reduces poor contact caused by mechanical vibration, thus improving the user experience.
[0052] Furthermore, such as Figure 1-5 and Figure 14 The breast pump shown has a heating component connection structure, wherein the contact portions of the first power supply terminal 221 and the second power supply terminal 311 are both made of copper.
[0053] The contact portions of the first power supply terminal 221 and the second power supply terminal 311 in this invention are both made of copper, which makes full use of the good conductivity and durability of copper, thereby effectively improving the efficiency and stability of power transmission. Furthermore, this design can also effectively reduce the resistance between the first power supply terminal 221 and the second power supply terminal 311, reduce the loss of power during transmission, and enhance the durability of the first power supply terminal 221 and the second power supply terminal 311, thereby extending their service life.
[0054] Example 2:
[0055] Furthermore, such as Figure 6-9 and Figure 14The breast pump shown has a heating component connection structure, wherein the second power supply terminal 311 has an energized contact portion 3111 on its side, the energized contact portion 3111 protrudes from the surface of the second power supply terminal 311, and the energized contact portion 3111 has multiple portions.
[0056] This invention improves the stability and reliability of the electrical connection by providing multiple energized contact portions 3111 protruding from the side of the second power supply terminal 311, effectively solving the problems of small conductive area and unstable power transmission caused by traditional magnetic probe point contact methods. Furthermore, this arrangement not only increases the actual conductive area and improves the current carrying capacity, but also compensates for component wear caused by manufacturing tolerances or long-term use to a certain extent, ensuring the continuous stability of power transmission. Furthermore, the multiple energized contact portions 3111 ensure that even in the presence of slight vibration or positional displacement, at least one contact portion maintains a good electrical connection, further enhancing the stability of the connection. This enhances the safety of equipment use and the overall user experience. Furthermore, in this embodiment, the connection terminal 27 is a TYPE-C connector. By using a TYPE-C connector as the connection terminal 27, the problems of small conductive area and limited current carrying capacity in traditional power supply structures are effectively solved, effectively improving the stability and reliability of electrical connections. Furthermore, as a standardized interface, the TYPE-C connector helps reduce production costs. Furthermore, the TYPE-C connector supports bidirectional plugging and unplugging, eliminating the need to distinguish between the front and back sides. This eliminates the need to consider directionality when connecting to the heating component 21, simplifying the assembly process and reducing potential risks caused by misoperation.

[0059] This invention provides a silicone-made connecting end 23 on the connecting terminal 27 for connection with the heating component 21. This not only allows the connecting terminal 27 to be positioned on the outside of the bra 2, but also achieves a flexible design. This allows the direction of the connecting terminal 27 to be adjusted via the flexible connecting end 23 after the bra 2 is installed on the mounting end face 32, making it easier to insert the connecting terminal 27 into the mating hole 31. This design effectively enhances the user's ease of operation. Furthermore, by placing the wire inside the connecting end 23, and by integrally molding the connecting end 23 with the first flexible part 24, the second flexible part 25, the heating component 21, and the connecting terminal 27 through a rubber coating, a sealing effect is achieved, preventing external moisture and impurities from entering the connecting end 23 and damaging the wire.
[0060] Furthermore, such as Figure 10-14 The illustration shows a breast pump with a heating component connection structure, wherein the first power supply end 221 is disposed on the side of the mating end 222, the first power supply end 221 protrudes from the surface of the mating end 222, and the first power supply end 221 is provided in multiple manner.
[0061] This invention improves the stability and reliability of the electrical connection by setting the first power supply end 221 on the side of the mating end 222 and making it protrude from the surface of the mating end 222, and by setting multiple first power supply ends 221. Furthermore, this setting not only effectively solves the problems of small conductive area and unstable power transmission caused by the traditional magnetic probe point contact method, but also improves the current carrying capacity by increasing the actual conductive area, ensuring efficient and stable power transmission. Furthermore, by setting multiple protruding first power supply ends 221, a good electrical connection can be maintained even under less than ideal plugging conditions.
