Description

Technical Field

[0001] This utility model relates to the field of maternal and infant feeding technology, specifically a breast pump that is easy to connect to a circuit. Background Technology

[0002] A breast pump is a tool used to express breast milk that has accumulated in the breasts. It is especially suitable for mothers who want to breastfeed but still need to continue working. With the help of a breast pump, users can express breast milk at work and bring it home to feed their babies after get off work. This can relieve the discomfort of engorgement and increase milk production. Expressing milk in a timely manner is beneficial for the production of new milk.

[0003] A breast pump is a component of a breast pump designed to fit against the user's skin. Future development of breast pumps will include a variety of functional modules such as heat therapy, massage, and light emission. However, more convenient wiring and cable management are relatively rare in the market. Some breast pumps have long, coiled cables that are easy to tangle and difficult to store. In some cases, the position of the protruding cable affects the normal expression of breast milk, making it inconvenient for users.

[0004] To address the above shortcomings, we need to develop a breast pump that is easy to connect to the circuit to meet the needs of a wide range of users. Utility Model Content

[0005] To address the aforementioned problems with existing breast pumps, such as tangled power cords, difficulty in storage, and even interference with normal pumping function, the technical solution adopted by this invention is as follows:

[0006] A breast pump that facilitates circuit connection includes a main unit for providing suction and a breast shield with functional modules. The breast shield is provided with an electrical interface for connecting the functional modules, and the main unit is provided with an electrical connector for controlling the functional modules. The electrical connector is detachably connected to the electrical interface so that the circuit between the main unit and the functional modules can be connected and disconnected.

[0007] Furthermore, the breast shield includes a fitting portion for conforming to the user's skin and a hollow, through-hole channel portion, with the electrical interface located outside the channel portion and away from the fitting portion.

[0008] Furthermore, the breast shield includes a fitting portion for conforming to the user's skin and a hollow, through-hole channel portion, with the electrical interface located outside the fitting portion and away from the channel portion.

[0009] Furthermore, it also includes a three-way tube and a milk storage container. The three-way tube is detachably installed on the main unit, the breast pump cover, and the milk storage container. The three-way tube is provided with an adapter structure for circuit connection. The channel section is connected to the milk storage container through the three-way tube, and the electrical connector is connected to the circuit of the electrical interface through the adapter structure.

[0010] Furthermore, the adapter structure is located on the side of the three-way tube away from the milk storage container. The adapter structure is provided with an adapter and an adapter interface for connecting the auxiliary circuit. The adapter is located on the side of the three-way tube closer to the breast pump, and the adapter interface is located on the side of the three-way tube closer to the main unit.

[0011] Furthermore, the main unit is connected to the breast pump via an air tube, and an extension cable for extending the connection distance is provided between the main unit and the electrical connector.

[0012] Furthermore, the outer side of the extension wire and the outer side of the air pipe are integrally formed and fixedly connected to form a dual-purpose gas and electricity pipeline, and the first and last ends of the dual-purpose gas and electricity pipeline adopt a bifurcated structure.

[0013] Furthermore, the host includes a telescopic mechanism for retracting and storing the extension cable. The telescopic mechanism has an elastic rotating element that can be elastically rotated and reset inside. The extension cable is wound around the outside of the elastic rotating element of the telescopic mechanism and extends out of the telescopic mechanism.

[0014] Furthermore, the electrical connector is a magnetic head, the electrical interface is a magnetic port, and the electrical connector and the electrical interface are connected by magnetic attraction.

[0015] Furthermore, the electrical connector adopts a USB connection standard connector structure, and the electrical interface adopts a USB connection standard interface structure.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model has a separate electrical interface on the breast pump with functional modules and a separate electrical connector on the main unit. By plugging the electrical connector into the electrical interface, the circuit between the main unit and the functional modules can be connected. The size of the electrical interface and the electrical connector are relatively small compared to the size of the breast pump, so they will not affect the normal use of the breast pump and there will be no problem of wire tangling, making it convenient for users.

[0018] 2. This utility model features an adapter structure on the T-pipe, located on the outer wall of the T-pipe. The adapter connects to the electrical interface, which satisfies the need for circuit connectivity, avoids wire tangling, and eliminates the problem of storing long and coiled wires, making it convenient for users.

[0019] 3. To enable the main unit to be used independently without the breast pump for extended distances via the air tube, this utility model employs an extension cord to increase the connection range of the electrical connector. Furthermore, the extension cord and air tube are integrally formed into a dual-purpose air-electric conduit, reducing the number of conduits. One dual-purpose air-electric conduit can meet the connection requirements of both the electrical and air circuits. The two ends of the dual-purpose air-electric conduit feature a branching structure to accommodate the branching connections in the electrical and air circuits, ensuring normal use while also facilitating storage and user convenience.

[0020] 4. This utility model adopts a telescopic structure with elastic rotation and reset on the main unit. After the extension cord is pulled out for use, the extension cord can be automatically retracted into the main unit by the elastic rotation and reset characteristics of the telescopic structure. Even during use, the extension cord can be affected by the elastic rotation and reset, so that the extension cord will not easily become tangled or curled, making it convenient for users to store and use.

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] Optionally, in some embodiments, the breast pump 200 may be made of soft materials such as silicone, rubber, or plastic. Preferably, the breast pump 200 is made of silicone, which makes it easier to conform to the user's skin. The silicone material has good softness, elasticity, and durability. The softness of the silicone material can conform to the shape of the breast, reduce pressure on the breast, and improve the user's comfort. The elasticity of the silicone material can be adjusted appropriately according to the size of the breast to ensure a good seal for effective milk collection. Silicone is a non-toxic material that will not chemically react with breast milk, is easy to clean, can be sterilized at high temperatures, and can withstand multiple washes and reuses without damage.

[0035] Example 1:

[0036] like Figures 1 to 8 The illustrated breast pump, which facilitates circuit connection, includes a main unit 100 for providing suction and a breast shield 200 with functional modules. The main unit 100 is a breast pump driven by a motor that evacuates air from inside the breast shield 200, achieving negative pressure milk extraction. The main unit 100 can be directly installed and connected to the breast shield 200 to evacuate air from the breast shield 200 and create a negative pressure state. The main unit 100 includes a circuit board for the control module, a battery for power supply, and an extraction pump for suction. The breast shield 200 is made of a translucent soft material. When the breast shield 200 is installed and fits against the user's skin, it forms a sealed space. The main unit 100 can be activated to create a negative pressure state by evacuating air. The breast shield 200 is divided into two parts: the fitting part 21 and the channel part 22. The fitting part 21 is the fitting surface structure of the breast shield 200 that comes into contact with the user's breast skin. The fitting part 21 has an arc-shaped curved surface structure that is easy to fit the shape of the breast. The arc-shaped curved surface structure can produce elastic deformation under the action of silicone material to adapt to the different breast shapes of users. The channel part 22 is the channel structure of the breast shield 200 for milk to flow out. The channel part 22 is provided with a hollow through milk passage. The milk passage connects to the fitting part 21 so that the milk squeezed out of the breast flows out through the milk passage. The connection and intersection of the fitting part 21 and the milk passage adopts a rounded corner structure for a smooth transition, which is more comfortable for the user's skin and avoids leaving boundary marks on the skin from sharp corners.

[0037] More specifically, the breast pump 200 can be equipped with one or more functional modules 24, such as hot compress, cold compress, electrotherapy, and massage. The breast pump 200 has an electrical interface 23 for connecting the functional modules 24. The electrical interface 23 serves as a power supply plug-in structure for connecting the functional modules 24 to an external power source. After being powered on, the electrical interface 23 can supply power to the functional modules 24 to start operation. The main unit 100 has an electrical connector 11 for controlling the functional modules. The electrical connector 11 serves as a power supply plug-in structure for connecting the main unit 100 to the functional modules 24. The electrical interface 23 and the electrical connector 11... 1. A plug-in structure that simply supplies power can be used, or a plug-in structure that allows for data exchange can be used. The electrical connector 11 is detachably connected to the electrical interface 23, so that the circuit between the host 100 and the functional module can be connected and disconnected. More specifically, in use, when the electrical connector 11 is inserted into the electrical interface 23, the circuit between the host 100 and the functional module is connected, and the host 100 can be powered on to control the functional module 24 to start. When the electrical connector 11 is pulled out of the electrical interface 23, the circuit between the host 100 and the functional module is disconnected, and the functional module 24 stops running after being powered off.

[0038] More specifically, such as Figures 1 to 3 as well as Figure 7 As shown, in this embodiment, the electrical interface 23 is located outside the fitting part 21 and away from the channel part 22. This position of the electrical interface 23 is suitable for use in small and compact integrated breast pumps or wearable breast pumps. It can meet the circuit connection between the functional module 24 and the main unit 100 from a structural position. This type of breast pump has the characteristics of compact structure, reducing the space required for installation, making the overall size smaller, which is convenient for users to use, carry and store. In addition, the size of the electrical interface 23 and the electrical connector 11 are relatively small compared to the size of the breast pump, so they will not affect the normal use of the breast pump and there will be no problem of wire tangling, which is convenient for users to use.

[0039] Example 2:

[0040] Based on Example 1, such as Figures 4 to 6 as well as Figure 9 and Figure 10 The breast pump shown here is easy to connect to the circuit. Unlike embodiment 1, the electrical interface 23 of this embodiment is located outside the channel portion 22 and away from the fitting portion 21. This arrangement of the electrical interface 23 is suitable for integrated or separate breast pumps with relatively ample space. It can meet the installation or placement requirements of the main unit from a structural perspective. It is also easier and more convenient to manufacture. This type of breast pump can accommodate a main unit with higher power and more functions, as well as a larger milk storage container. It is also more detachable, making it convenient for users to disassemble and clean.

[0041] Example 3:

[0042] Based on Example 2, such as Figures 4 to 6 as well as Figure 9 and Figure 10 The illustrated breast pump, which facilitates circuit connection, also includes a three-way tube 300 and a milk storage container 400. The three-way tube 300 is detachably used to install the main unit 100, the breast shield 200, and the milk storage container 400. The channel section 22 is connected to the milk storage container 400 through the three-way tube 300. More specifically, the three-way tube 300 has three interconnected ports: one for mounting the main unit 100, one for mounting the breast shield 200, and one for mounting the milk storage container 400. The milk storage container 400 has a bottle-shaped milk storage chamber for storing milk. After collecting milk in the bottle-shaped milk storage chamber, it is ready for feeding the baby. In use, the main unit 100 can draw air from the breast shield 200 through the three-way tube 300 to create a negative pressure state. Under the action of negative pressure, milk flows out from the nipple, flows through the milk channel, and flows through the three-way tube 300 into the milk storage container 400, where it is stored in the bottle-shaped milk storage chamber, thus realizing the functions of milk extraction and storage.

[0043] More specifically, the tee pipe 300 is provided with a converter structure 31 for circuit connection. The converter structure 31 is a circuit conversion structure used to assist in connecting the electrical connector 11 and the electrical interface 23. It can be an adapter cable or an adapter plug. The converter structure 31 is fixedly formed on the outer wall of the tee pipe 300. One end of the converter structure 31 is inserted into the power connector 11, and the other end of the converter structure 31 is connected to the electrical interface 23. The electrical connector 11 is connected to the circuit of the electrical interface 23 through the converter structure 31 to realize the smooth connection of the circuit. This can not only satisfy the circuit connection, but also avoid the wire tangling and the problem of storing long and coiled wires, making it convenient for users.

[0044] Example 4:

[0045] Based on Example 3, such as Figure 9 and Figure 10The illustrated breast pump facilitates circuit connection. An adapter structure 31 is located on the side of the three-way tube 300 away from the milk storage container 400. The adapter structure 31 is formed by rubber coating on the outer wall of the three-way tube 300. The adapter structure 31 is equipped with an adapter 32 and an adapter interface 33 for auxiliary circuit connection. The adapter 32 is located on the side of the three-way tube 300 closer to the breast pump cover 200, and the adapter interface 33 is located on the side of the three-way tube 300 closer to the main unit 100. The adapter 32 can adopt the same connector structure as the electrical connector 11, and the adapter interface 33 can adopt the same interface structure as the electrical interface 23 to ensure the compatibility and stability of the circuit connection. This structure facilitates user installation, use, and cleaning. It connects the circuit between the main unit 100 and the functional module 24 with a shorter connection distance, eliminating the need for users to wrap or tie long wires. This satisfies the need for circuit connection while avoiding wire tangling and the problem of storing long, coiled wires, making it convenient for users.

[0046] Example 5:

[0047] Based on Example 1 or Example 2, such as Figure 11 The illustrated breast pump is designed for easy circuit connection. The main unit 100 is connected to the breast shield 200 via an air tube 13. Since the main unit 100 has a certain weight, in the structure of a split-type breast pump, the main unit 100 is generally separated from the breast shield 200 and placed in an empty space next to it. This reduces the weight of the breast pump when in use, and reduces the user's hand fatigue and burden. More specifically, the air tube 13 is used to extend the placement range of the main unit 100, so that the user can place the main unit 100 on a nearby table or in a space. Even if the main unit 100 is placed next to the body, the breast shield 200 can still be pumped through the air tube 13, making it convenient for the user to use.

[0048] More specifically, to accommodate the use of the air tube 13 to extend the placement distance of the main unit 100, an extension wire 12 for extending the connection distance is provided between the main unit 100 and the electrical connector 11. The electrical connector 11 is located at the end of the extension wire 12 away from the main unit 100. The main unit 100 extends the insertion distance of the electrical connector 11 through the extension wire 12, so that the electrical connector 11 can be smoothly inserted into the electrical interface 23, which is convenient for users.

[0049] Example 6:

[0050] Based on Example 3 or Example 4, such as Figure 10The illustrated breast pump is designed for easy circuit connection. The main unit 100 is connected to the breast shield 200 via an air tube 13 and a three-way tube 300. Since the main unit 100 has a certain weight, in the structure of a split-type breast pump, the main unit 100 is generally separated from the breast shield 200 or the three-way tube 300 and placed in an empty space to reduce the weight of the breast pump when in use, thereby reducing hand fatigue and burden for the user. More specifically, the air tube 13 is used to extend the placement range of the main unit 100, allowing the user to place the main unit 100 on a nearby table or in a space. Even if the main unit 100 is placed next to the body, the user can still pump air from the breast shield 200 via the air tube 13 and the three-way tube 300, making it convenient for the user to use.

[0051] More specifically, to accommodate the use of the air tube 13 to extend the placement distance of the main unit 100, an extension cable 12 for extending the connection distance is provided between the main unit 100 and the electrical connector 11. The electrical connector 11 is located at the end of the extension cable 12 away from the main unit 100. The main unit 100 extends the insertion distance of the electrical connector 11 through the extension cable 12, so that the electrical connector 11 can be smoothly inserted into the adapter 33 and connected to the electrical interface 23 through the adapter structure 31, which is convenient for users.

[0052] Example 7:

[0053] Based on Example 5 or Example 6, such as Figure 10 The breast pump shown is designed for easy circuit connection. The outer side of the extension cord 12 and the outer side of the air tube 13 are integrally molded and fixedly connected to form a dual-purpose air-electric cable 500. More specifically, the outer side of the extension cord 12 is molded onto the outer side of the air tube 13 using an adhesive coating process, allowing the extension cord 12 and the air tube 13 to be bound together as one unit. The extension cord 12 and the air tube 13 have similar lengths. The first and last ends of the dual-purpose air-electric cable 500 are respectively equipped with a forked structure 51, allowing the extension cord 12 and the air tube 13 to be connected to their respective interface structures independently without changing the original interface structures. The forked structure 51 can satisfy the requirement that the extension cord 12 can be connected to the electrical interface 23 or the adapter interface 33 independently, while also allowing the air tube 13 to be connected to the three-way pipe 300. This satisfies the need for circuit connection, avoids wire tangling, and eliminates the problem of storing long and coiled wires, making it convenient for users.

[0054] Example 8:

[0055] Based on Example 5 or Example 6, such as Figure 11 and Figure 12The illustrated breast pump, facilitating circuit connection, includes a main unit 100 comprising a telescopic mechanism 14 for retracting and storing an extension cord 12. The telescopic mechanism 14 is installed inside the main unit 100 and includes a resilient rotating element 141 capable of elastically rotating and resetting. The resilient rotating element 141 contains a hollow, through-hole drum and a coil spring sleeved on the outside of the drum. The resilient rotating element 141 can rotate circumferentially around the center of the telescopic mechanism 14. The extension cord 12 is wound in a spiral shape around the outside of the resilient rotating element 141. During use, the user pulls... The electrical connector 11 causes the extension cord 12 to be pulled out by external force. The extension cord 12 drives the elastic rotating element 141 to rotate in the positive direction. The coil spring rotates synchronously under the influence of the rotation and accumulates elastic force. When the user releases the electrical connector 11, the extension cord 12 loses the influence of external force, so the elastic force of the coil spring is greater than the influence of external force, generating a reset force. The reset force drives the elastic rotating element 141 to rotate in the opposite direction, and the elastic rotating element 141 can drive the extension cord 12 to retract, so that the extension cord will not easily become tangled or coiled, making it convenient for users to store and use.

[0056] Example 9:

[0057] Based on any of the above embodiments, the electrical connector 11 of the host 100 adopts a magnetic head, and the electrical interface 23 adopts a magnetic port. The electrical connector 11 and the electrical interface 23 are connected by magnetic attraction. More specifically, both the magnetic head and the magnetic port are provided with magnetic metal parts. When in use, the electrical connector 11 is brought close to the electrical interface 23 and makes contact with magnetic attraction to achieve magnetic connection. After the electrical connector 11 contacts the electrical interface 23, the circuit is connected. When disassembling, it can be pulled out directly. Compared with plug-in connection, magnetic connection is more convenient to use, and the force required by the user's hand when connecting is also less, which improves the efficiency of connection and disassembly.

[0058] Example 10:

[0059] Based on any of the above embodiments, such as Figures 1 to 10 The breast pump shown is designed for easy circuit connection. The electrical connector 11 adopts a USB standard connector structure, and the electrical interface 23 adopts a USB standard interface structure. More specifically, both the connector structure of the electrical connector 11 and the interface structure of the electrical interface 23 adopt a USB Type-C standard plug-in structure. This connection structure enables power supply and data exchange, facilitating the host 100 to further control the functional modules of the breast pump 200. It is also beneficial for data flow and module control and adjustment when data feedback such as temperature feedback, vibration feedback, light feedback, and electrical pulse feedback is required.
