Description

Technical Field

[0001] This utility model relates to the field of breast pumps, specifically a connection structure for functional components of a breast pump and a breast pump itself. Background Technology

[0002] As a maternal and infant care device that assists in breastfeeding, a breast pump extracts milk by mimicking the sucking motion of an infant. To enhance user comfort, some breast pumps integrate heating or massage functions. These functional components are usually integrated into the bra and electrically connected to the main unit via connection terminals.

[0003] Currently, this type of electrical connection is generally achieved by inserting the connector on the breast pump into the connector of the main unit, which has pins. This allows the pins on the main unit's connector to contact the metal contact of the connector, thus conducting current. However, this connection structure still has shortcomings. This connection relies on the deformation of the metal contact to ensure a tight connection. When the breast pump vibrates during operation, because the breast pump cover is made of flexible material, the pins on the connector can detach from the metal contact of the connector, causing the electrical connection to break and affecting the normal operation of the breast pump.

[0004] Therefore, it is necessary to develop a connection structure for the functional components of a breast pump and a breast pump in order to improve the electrical connection stability between the functional components and the power supply. Utility Model Content

The described embodiments are merely some, not all, of the embodiments of this utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0042] Example 1: Please see Figure 1-22 The present invention discloses a connection structure for a breast pump functional component, including a bra 1, a functional component 3 located on the bra 1, and a main unit 2 connected to the bra 1. The functional component 3 is provided with a connection terminal 31. The main unit 2 includes a mating end 21 that mates with the connection terminal 31, a conductive contact portion 22 located on the mating end 21 and used for electrical connection with the connection terminal 31, and an elastic component 23. The elastic component 23 is connected to the mating end 21 or the conductive contact portion 22 so that the mating end 21 or the conductive contact portion 22 is elastically arranged.

[0043] This invention allows the mating end 21 to be elastically set, ensuring that when the breast pump vibrates during operation, the mating end 21 can adapt to the positional changes of the connecting terminal 31, so that the connecting terminal 31 always maintains tight contact with the conductive contact part 22, effectively avoiding the problem of the connecting terminal 31 and the contact surface of the conductive contact part 22 separating due to vibration. This invention also allows the conductive contact 22 to be elastically configured, so that the connecting terminal 31 and the conductive contact 22 can be electrically connected through elastic contact, ensuring that even when the breast pump vibrates, the contact between the connecting terminal 31 and the conductive contact 22 can be maintained, thereby ensuring the stability of the electrical connection.

[0044] Traditional breast pumps often rely on the deformation of the metal contact portion to ensure a tight contact between the connecting terminal 31 and the pins on the main unit 2. This design can easily lead to the contact surface breaking due to vibrations during breast pump operation, resulting in poor contact. However, this invention addresses this issue by providing a mating end 21 on the main unit 2 and using an elastic component 23 to elastically position the mating end 21 or conductive contact 22. This ensures that even when the breast pump vibrates during operation, the connecting terminal 31 maintains good contact with the conductive contact 22. Specifically, in this embodiment, the mating end 21 is elastically configured. When the breast pump vibrates and the connecting terminal 31 is subjected to external force and slightly deviates from the original contact point, the conductive contact part 22 will automatically move closer to the connecting terminal 31 with the help of the rebound force provided by the elastic component 23, and provide a constant pressure to maintain the physical contact and electrical connection between the two. Furthermore, the configuration of this utility model can effectively avoid the problem of the contact surface of the connecting terminal 31 and the mating end 21 separating due to vibration, thereby improving the stability of the connection and reducing the possibility of poor contact. Furthermore, in other embodiments, the mating end 21 can be configured to be elastically configured, so that the mating end 21 can effectively absorb the impact force generated by the vibration of the equipment during the operation of the breast pump, ensuring that even under strong shaking, the mating end 21 can adjust its own position according to the position of the connecting terminal 31, thereby ensuring that the connecting terminal 31 can always maintain contact with the conductive contact part 22. Furthermore, in this embodiment, the elastic component 23 is made of stainless steel and has conductivity.

[0045] Furthermore, such as Figure 1-22 The diagram shows a connection structure for a breast pump functional component, wherein the connection terminal 31 is provided with an energized part 311 that is electrically connected to the conductive contact part 22, the mating end 21 is provided with a mating hole 211 for the connection terminal 31 to be inserted, and the main unit 2 or the mating hole 211 is provided with a sliding hole 212 for the mating end 21 or the conductive contact part 22 to slide.

[0046] In this embodiment, by providing a mating hole 211 for inserting the connecting terminal 31 into the mating end 21, it is ensured that the connecting terminal 31 can be stably and accurately mated with the conductive contact 22 on the host 2, thereby improving the reliability and stability of the electrical connection. Furthermore, since the mating hole 211 is provided with a sliding hole 212 for sliding the conductive contact 22, the movement direction of the conductive contact 22 is limited. Even if the connecting terminal 31 moves slightly along the direction of the mating hole 211 due to the vibration of the breast pump, thus tending to move away from the conductive contact 22, this setting allows the conductive contact 22 to be supported by the elastic force of the elastic component 23 and the sliding hole 212. Under the guiding effect, the conductive contact 22 and the connecting terminal 31 are always kept in contact, thereby ensuring the stability of the electrical connection. Furthermore, in the embodiment where the mating end 21 is elastically set, the main unit 2 is provided with a sliding hole 212 for the mating end 21 to slide, which ensures the sliding direction of the mating end 21 itself, so that it can better adapt to the movement direction of the connecting terminal 31 caused by vibration. Even in a strong vibration environment, the mating end 21 can still automatically adjust its own position according to the position change of the connecting terminal 31, thereby maintaining close contact between the two, effectively enhancing the stability of the electrical connection during the operation of the breast pump, and reducing phenomena such as electrical connection interruption or instability caused by equipment vibration.

[0047] Furthermore, such as Figure 1-22 The diagram shows a connection structure for a breast pump functional component 3, wherein the functional component 3 includes a heating component 32 connected to a connection terminal 31, the heating component 32 being located inside a bra 1, the connection terminal 31 extending from the surface of the bra 1 and connecting to a mating end 21, and the connection terminal 31 and the bra 1 being integrally formed by overmolding.

[0048] In this invention, the heating component 33 is located inside the bra 1, and the first mating end 31 extends from inside the bra 1 to the surface, thus facilitating connection with the mating hole 22 on the main unit 2. This arrangement ensures that the heating component 33 can directly heat the bra 1, improving heating efficiency and uniformity, and providing a more comfortable experience for the user. Furthermore, in this embodiment, the heating component 32 and the connecting terminal 31 are integrally formed by welding, and the integrally formed part is bonded to the bra 1. This arrangement enhances the sealing of the connection between the first mating end 31 and the bra 1, preventing external moisture and dust from entering and damaging the heating component 32.

[0049] Furthermore, such as Figure 1-22The diagram shows a connection structure for a breast pump functional component, wherein the energized part 311 includes a first energized contact piece 3111, the conductive contact part 22 is columnar, the main unit 2 also includes a circuit assembly 24 fixed inside the main unit 2, one end of the elastic component 23 is connected to the circuit assembly 24, and the other end is connected to the conductive contact part 22, so that the conductive contact part 22 is located in the sliding hole 212 and slides elastically along the direction of the mating hole 211.

[0050] This invention, by setting a first energized contact piece 3111 at the front end of the connecting terminal 31 and allowing the conductive contact part 22 to slide along the direction of the mating hole 211 to contact the first energized contact piece 3111, ensures that after the connecting terminal 31 is inserted into the mating hole 211, the conductive contact part 22 can always maintain good contact with the first energized contact piece 3111 in the direction of the mating hole 211, thus improving the continuity and stability of power transmission. Furthermore, the columnar design of the conductive contact part 22 facilitates the smooth sliding of the conductive contact part 22 and reduces the problem of poor contact caused by sliding jamming due to friction. Furthermore, the host 2 also includes a circuit assembly 24 fixed inside it, and one end of the elastic component 23 is welded to the circuit assembly 24, and the other end is abutted to the conductive contact part 22. This not only allows the conductive contact part 22 to slide back and forth elastically in the sliding hole 212, but also ensures the stability of power transmission by welding the elastic component 23 to the circuit assembly 24.

[0051] Furthermore, such as Figure 1-22 The diagram shows a connection structure for a breast pump functional component, wherein the conductive contact portion 22 is provided with an inner cavity 221 into which the elastic component 23 extends, and a first limiting end 222 that prevents the conductive contact portion 22 from disengaging from the sliding hole 212, and the cross section of the end of the conductive contact portion 22 that contacts the first energized contact piece 3111 is arranged in an arc shape.

[0052] This invention ensures that the elastic component 23 can effectively provide the required elastic support by providing an inner cavity 221 for the elastic component 23 to extend into the conductive contact portion 22. This allows the conductive contact portion 22 to move more flexibly when subjected to external forces, thereby adapting to various vibration environments and ensuring the stability of the electrical connection. Furthermore, by providing a first limiting end 222 in the conductive contact portion 22 to prevent it from disengaging from the sliding hole 212, specifically, the elastic component 23 is connected to the circuit component 24 fixed in the host 2. Under the action of the elastic force of the elastic component 23, the conductive contact portion 22 moves towards the bra 1 side, while the first limiting end 222 can effectively prevent the conductive contact portion 22 from moving excessively towards the bra 1 side, thereby avoiding the risk of disengaging from the mating hole 211. Furthermore, by setting the cross-section of the end of the conductive contact portion 22 that contacts the first energized contact piece 3111 to be arc-shaped, the contact area is increased, thereby increasing the stability of the electrical connection.

[0053] Furthermore, such as Figure 1-22 The diagram shows a connection structure for a breast pump functional component, wherein the connection terminal 31 is further provided with an insulating component 3112 located around the first energized contact piece 3111. The sliding direction of the first energized contact piece 3111 and the conductive contact portion 22 is inclined. Magnets are provided on both the connection terminal 31 and the mating end 21.

[0054] This invention effectively avoids current leakage and other electrical faults by providing an insulating component 3112 around the first energized contact piece 3111, thus improving safety. Furthermore, by setting the contact direction between the first energized contact piece 3111 and the conductive contact portion 22 in an inclined state, this arrangement helps reduce pressure during contact, effectively reducing wear between the first energized contact piece 3111 and the conductive contact portion 22, and extending service life. Furthermore, by providing magnets at the connecting terminal 31 and the mating end 21, the connection strength between the two is effectively enhanced, reducing connection instability caused by vibrations generated during breast pump operation, and ensuring the continuity and reliability of breast pump operation. Furthermore, in this embodiment, the magnet is embedded inside the connecting terminal 31 and integrally formed with the breast shield 1 through a rubber coating.

[0055] Furthermore, both the energized part 311 and the conductive contact part 22 are provided in at least three or more forms. In this embodiment, three energized parts 311 and three conductive contacts 22 are provided respectively, and three energized contact pieces 313 are used to connect the ground wire, the power line and the temperature control signal line respectively. Furthermore, in other embodiments, other functions such as massage and cold compress can be added to the bra 1, so the energized part 311 and the conductive contact part 22 can be provided in more than three forms.

[0056] Furthermore, in this embodiment, both the energized part 311 and the conductive contact part 22 are made of stainless steel, so that they will not rust even when frequently rinsed; further, in other embodiments, the elastic contact part 221 may also be made of other conductive metals.

[0057] Example 2: Furthermore, such as Figure 1-22 The diagram shows a connection structure for a breast pump functional component, wherein the main unit 2 further includes a sliding seat 25 fixed in a sliding hole 212, the sliding seat 25 is provided with a first sliding cavity 251 for the conductive contact part 22 to slide, the elastic component 23 is located in the first sliding cavity 251, and the conductive contact part 22 and the first energized contact piece 3111 are electrically connected through elastic planar contact.

[0058] This invention provides a sliding seat 25 fixed to the sliding hole 212 in the main unit 2, and a first sliding cavity 251 for the conductive contact part 22 to slide in the sliding seat 25. This arrangement avoids the wear problem caused by the conductive contact part 22 directly contacting the sliding hole 212, thus extending its service life. Furthermore, the sliding seat 25 is detachable and replaceable, which facilitates subsequent maintenance. Furthermore, the arrangement that the conductive contact part 22 and the first energized contact piece 3111 achieve electrical connection through elastic planar contact not only increases the contact area, but also ensures the stability and continuity of the electrical connection.

[0059] Example 3: The difference between this embodiment and Embodiment 1 is that the mating end 21 is elastically configured, while the conductive contact part 22 is not elastically configured. This allows the mating end 21 to effectively absorb the impact force generated by the vibration of the device during the operation of the breast pump. It ensures that even under strong shaking, the mating end 21 can adjust its position according to the position of the connecting terminal 31, thereby ensuring that the connecting terminal 31 can always maintain contact with the conductive contact part 22.

[0060] Furthermore, such as Figure 1-22 The diagram shows a connection structure for a breast pump functional component, wherein the main unit 2 is further provided with a second sliding cavity 26 for sliding of the mating end 21, the mating end 21 is further provided with a limiting step 213 and a second limiting end 214 to prevent the mating end 21 from disengaging from the sliding hole 212, and the elastic component 23 is elastically connected to the bottom of the limiting step 213 and the second sliding cavity 26 respectively.

[0061] This invention, by providing a second sliding cavity 26 in the host 2 for the mating end 21 to slide, not only ensures the guiding nature of the mating end 21 during the sliding process, but also provides protection for the mating end 21, preventing damage to the mating end 21 caused by external factors. Furthermore, the mating end 21 is also provided with a limiting step 213 and a second limiting end 214, and the sliding hole 212 is located between the limiting step 213 and the second limiting end 214. This arrangement effectively prevents the mating end 21 from disengaging from the sliding hole 212. Furthermore, the setting of the limiting step 213 can also ensure that when the connecting terminal 31 is inserted into the mating hole 211, the mating end 21 stops moving after reaching the predetermined position, ensuring that the connecting terminal 31 can be fully and accurately inserted into the mating hole 211, avoiding the situation where the connecting terminal 31 cannot be fully inserted due to excessive clearance of the mating end 21.

[0062] Furthermore, such as Figure 1-22The diagram shows a connection structure for a breast pump functional component, wherein the energized part 311 further includes an elastic contact part 3113 protruding from the side of the connection terminal 31, and the conductive contact part 22 is disposed on the inner side wall of the mating hole 211, and the conductive contact part 22 is provided with a groove 2112 for fixing the position of the elastic contact part 3113.

[0063] In this invention, the energized part 311 is an elastic contact part 3113 protruding from the side of the connecting terminal 31. Simultaneously, the conductive contact part 22 is located on the inner wall of the mating hole 211 and elastically contacts the elastic contact part 3113 to achieve electrical connection. This arrangement, by placing the elastic contact part 3113 and the conductive contact part 22 on the side, perpendicular to the moving direction of the connecting terminal 31, avoids contact detachment caused by the connecting terminal 31 moving along the mating hole 211 due to vibration, effectively enhancing the stability and reliability of the electrical connection. Furthermore, the conductive contact part 22 is provided with a groove 2112 for fixing the position of the elastic contact part 3113. This arrangement allows the elastic contact part 3113 to be fixed in position after the connecting terminal 31 is inserted into the mating hole 211 through the cooperation of the elastic contact part 3113 and the groove 2112, thus preventing the elastic contact part 3113 from detaching from the conductive contact part 22 and ensuring the stability of the electrical connection.

[0064] Example 4: Furthermore, such as Figure 1-22 The breast pump shown includes a connection structure for the breast pump functional components and a milk storage chamber 4 connected to the main unit 2.

[0065] This invention applies the connection structure of the breast pump's functional components to the breast pump, which not only improves the functionality and user experience of the device, but also enhances the stability of the electrical connection by optimizing the electrical connection structure, ensuring the stability and safety of the device's operation. This effectively solves the problem of electrical connection interruption or instability that is prone to occur during the operation of traditional breast pumps. Furthermore, in this embodiment, the main unit 2 has a negative pressure milk suction function. By adding a milk storage chamber 4 connected to the main unit 2, this invention allows the milk sucked out by the main unit 2 to be directly stored in the milk storage chamber 4, which is convenient for subsequent use or storage without the need for additional transfer containers, thus improving user convenience and hygiene.
