[0001] This utility model relates to the field of maternal and infant products technology, and in particular to a breast pump and breast pump components. Background Technology

[0002] A breast pump is a tool used to express breast milk accumulated in the mammary glands. Currently, breast pumps are usually equipped with heating elements to ensure that the pump does not affect the user's comfort in cold weather and to maintain normal breast milk production. However, existing breast pumps are prone to problems such as water or milk entering the charging port, which can prevent charging and cause the heating unit to not heat up properly. Utility Model Content

[0003] The breast pump and breast pump components provided in this application are intended to solve the problem that existing charging ports cannot be charged due to water or milk entering, which in turn causes the heating unit to not heat up properly.

[0032] With technological advancements, people have higher expectations for breast pumps. Breast pumps typically consist of a breast shield and a main unit. The breast shield is designed to cover the breasts. Breast shields generally include auxiliary structures such as heating elements and vibration massagers. The heating element, such as a resistance wire, heats the breast shield to help increase milk production and flow rate through a warm compress function, preventing nipple engorgement and related problems; especially in winter, the warm compress function also increases comfort. Vibration massage can help prevent breast lumps.

[0033] In related technologies, heating resistance wires are typically installed on breast pumps. The heat generated when the resistance wire is energized is transferred to the outside of the breast pump, allowing the user to feel the warmth. However, installing heating resistance wires inside the breast pump involves a complex encapsulation process, low production yield, and high cost. Furthermore, because breast pumps need to be frequently removed from the main unit for cleaning and reinstallation, improper assembly often results in insufficient energization of the resistance wire, causing heating malfunctions. Additionally, the contact points between the main unit and the breast pump require exposed contact points; water or milk residue entering these exposed areas can damage the heating element, leading to heating failure.

[0034] In addition, in related technologies, breast pumps typically have their charging port located on the outside of the pump for charging. However, this can lead to water or milk getting into the charging port, preventing the pump from charging and further hindering the heating element from heating properly.

[0035] Therefore, this application provides a breast pump that reduces the risk of damage to the heating unit during the cleaning or boiling of the breast shield by placing the heating unit on the main unit. Simultaneously, it reduces the risk of improper assembly during repeated installation of the breast shield and main unit, leading to insufficient power supply and poor heating function. Furthermore, placing the heating unit on the main unit simplifies the manufacturing process, as the main unit typically does not require repeated cleaning or processes such as gluing the heating unit, resulting in higher production yield and lower cost. Additionally, the main unit includes a power supply unit that supplies power to the heating unit, and this power supply unit charges wirelessly, resolving the issue of external charging interfaces causing charging failures due to water or milk entering the charging port.

[0036] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a breast pump provided in one embodiment of this application; Figure 2 for Figure 1 The diagram shows a disassembled breast pump. In this embodiment, a breast pump 10 is provided, which includes a breast shield 1, a main unit 2, and a power supply unit.

[0038] A breast-sucking bra 1 is disposed on a housing 21 and configured to cover the breast. In some embodiments, the breast-sucking bra 1 includes a first cover body 1a and a second cover body 1b connected to each other, the first cover body 1a being connected to the housing 21. The second cover body 1b is arranged around the first cover body 1a, and the second cover body 1b and the first cover body 1a together form a trumpet shape for contacting the skin. The first cover body 1a and the second cover body 1b may simply be connected by contact; or they may be connected by other means such as adhesive.

[0039] The first cover 1a can be shaped like a trumpet and has a breast milk suction channel 11. Breast milk flows out through the breast milk suction channel 11. The first cover 1a is generally made of soft rubber, such as silicone. Silicone is soft and conforms well to the user's skin, which helps improve the user's comfort; in addition, silicone has a certain heat-insulating effect, which helps to slow down the cooling rate of the first cover 1a and improves the user's comfort.

[0040] In some embodiments, the first cover 1a is detachably connected to the main unit 2. This allows for the replacement of the first cover 1a with different sizes and types for different users, providing high adaptability. In addition, it also facilitates the cleaning of the first cover 1a and makes it convenient to use.

[0041] The main unit 2 is connected to the first breast shield 1a via the breast suction channel 11. The main unit 2 is configured to provide suction force to the breast shield 1, for example, to create a negative pressure inside the breast shield 1, so as to draw breast milk from the breast through the breast shield 1 and allow it to flow out of the breast shield 1 through the breast suction channel 11. Exemplarily, the main unit 2 includes at least a vacuum generator, which is connected to the breast suction channel 11 and creates a negative pressure in the breast shield 1. The vacuum generator may be a vacuum pump.

[0042] The main unit 2 includes a housing 21 and a heating unit 22 disposed within the housing 21. Specifically, the first cover 1a can be detachably connected to the housing 21. For example, the first cover 1a is plugged into the housing 21, and since the first cover 1a is made of an elastic material, the first cover 1a can be press-fitted with the housing 21 to improve the sealing of the connection between the first cover 1a and the main unit 2.

[0043] The heating unit 22 is connected to the breast shield 1 and electrically connected to the power supply unit. It generates heat when powered on to heat the breast shield 1, thereby achieving the heat therapy function of the breast shield 1. In one specific embodiment, the heating unit 22 is connected to the first shield body 1a. In another specific embodiment, the heating unit 22 is connected to the second shield body 1b. In yet another specific embodiment, heating units 22 are connected to both the first shield body 1a and the second shield body 1b.

[0044] The heating unit 22 may include any one or more of the following: flexible printed circuit (FPC), heating wire, heating sheet, and graphene.

[0045] The power supply unit is disposed inside the housing 21 corresponding to the heating unit 22 and supplies power to the heating unit 22. The power supply unit is charged wirelessly. In some embodiments, the power supply unit is attached to the heating unit 22 and supplies power to the heating unit 22.

[0046] In some embodiments, the host 2 further includes a first circuit board (not shown) and a controller (not shown). The power supply unit includes a receiving coil 23 and a power supply 24. The receiving coil 23 is electrically connected to the first circuit board, and the first circuit board is electrically connected to the power supply 24. The receiving coil 23 cooperates with a wireless charging socket to wirelessly charge the power supply 24. By charging the power supply 24 wirelessly, there is no need to provide a separate charging interface on the outside of the host 2, avoiding the problem of external moisture, breast milk, etc. entering the charging interface and causing the breast pump 10 to fail to charge properly, thereby improving the problem of the heating unit 22 not heating up properly.

[0047] The wireless charging socket (not shown) includes a transmitting coil. When the breast pump 10 needs charging, it is placed on the wireless charging socket. The transmitting coil converts the electrical signal into an electromagnetic signal and transmits the electromagnetic signal to a receiving coil coupled to the transmitting coil. The receiving coil receives the electromagnetic signal, converts it into an electrical signal (current), and transmits the electrical signal to the power source 24 to complete the wireless charging. The power source 24 can be a battery.

[0048] The controller is electrically connected to the heating unit 22 and the receiving coil 23 respectively, and is used to control the power supply to or from the heating unit 22; and to control whether to start wireless charging of the power supply 24.

[0049] In the above embodiments, by placing the heating unit 22 on the main unit 2, the risk of damaging the heating unit 22 during the process of cleaning or boiling the first cover 1a is reduced. Simultaneously, it reduces the risk of the heating unit 22 failing to receive power and exhibiting poor heating function due to improper assembly caused by repeated installation of the first cover 1a and the main unit 2. Furthermore, by providing a power supply unit to the heating unit 22 on the main unit 2 and enabling wireless charging, there is no need for an external charging interface on the main unit 2. This reduces the risk of the breast pump 10 failing to charge due to water or milk entering the charging interface, thereby further reducing the risk of the heating unit 22 failing to heat properly.

[0050] In some embodiments, the receiving coil 23 can serve as both a wireless charging receiving coil and a heating unit 22. This simplifies the structure of the breast pump 10 and reduces cost and manufacturing complexity.

[0051] Of course, in other embodiments, the heating unit 22 may be made of materials such as heating wire, heating sheet, or graphene, which are different from the receiving coil 23.

[0052] In some embodiments, the housing 21 includes a front housing 211 and a rear housing 212, which cooperate to form a hollow cavity. The heating unit 22, the receiving coil 23 and the power supply 24 are respectively disposed in the hollow cavity so as to protect the heating unit 22, the receiving coil 23 and the power supply 24 through the housing 21.

[0053] In some embodiments, combined with Figure 3 The front shell 211 is flared, and the first cover 1a is specifically fitted inside the front shell 211 and fits against the inner surface of the front shell 211.

[0054] The second cover 1b is connected in a ring shape to the peripheral edge of the front shell 211 and protrudes from the first cover 1a. The second cover 1b is configured to fit directly against the breast. This improves the seal of the breast pump 10 after it fits against the body, reducing the risk of breast milk leakage and insufficient vacuum suction. The second cover 1b may be a hollow closed ring.

[0055] In some embodiments, the front shell 211 and the second cover 1b can be integrally formed.

[0056] In some embodiments, combined with Figure 3 The heating unit 22 is shaped to match the second cover 1b, and the heating unit 22 is disposed on the side surface of the second cover 1b facing the rear shell 212. In this way, the heat generated by the heating unit 22 can be directly transferred to the human body through the second cover 1b, improving the heat transfer efficiency.

[0057] In some embodiments, the main unit 2 further includes an elastic cup 25, a through hole is provided on the rear shell 212, and an elastic wrist is provided on the rear shell 212 and covers the entire through hole, for regulating the pressure inside the hollow cavity of the main unit 2.

[0058] In some embodiments, combined with Figure 3 The breast pump 10 also includes a vibrating element 3, which is electrically connected to the controller and the power supply 24 respectively. The vibrating element 3 is located on the side of the housing 21 facing the first cover 1a. Specifically, the vibrating element 3 is located on the front housing 211. The vibrating element 3 is configured to drive the breast shield 1 to vibrate during vibration, thereby massaging the breast and stimulating milk production.

[0059] In some embodiments, see Figure 4 , Figure 4 for Figure 1 The diagram shows a vertical cross-sectional view of the breast pump 10; a portion of the vibrating element 3 protrudes from the front shell 211 on the side opposite to the rear shell 212. Thus, when the breast shield 1 is placed over the body, the vibrating element 3 can effectively contact the body, thereby better transmitting the vibration effect to the body and improving the massage effect of the vibrating element 3. The vibrating element 3 can be a motor.

[0060] In some embodiments, the first cover 1a covers the vibrator 3 along the axial direction Y of the housing 21. In this way, the vibrator 3 transmits vibrations to the human body through the silicone first cover 1a, making the vibration transmission process gentler and the force acting on the human body more uniform, which helps to improve the user's comfort.

[0061] In some embodiments, the first cover 1a is recessed on the side opposite to the rear shell 212 corresponding to the position of the vibrating element 3, forming a receiving groove, and the portion of the vibrating element 3 protruding from the front shell 211 is accommodated in the receiving groove. Compared to adding a soft rubber button pad, there is no need to open a relief hole on the first cover 1a to avoid the vibrating element 3, which can improve the sealing performance of the first cover 1a after it is in contact with the human body and reduce the risk of breast milk leakage; and the solution of directly forming a receiving groove in the first cover 1a is simpler in process and lower in cost than adding a soft rubber button pad.

[0062] In some embodiments, combined with Figure 3 The device comprises multiple vibrating elements 3, which are spaced apart along the circumferential direction of the front shell 211. This allows for the massage of different areas of the breast individually using multiple spaced vibrating elements 3, resulting in better massage uniformity. Specifically, the multiple vibrating elements 3 can be equally spaced along the circumferential direction of the front shell 211.

[0063] In some embodiments, the front shell 211 includes a flared portion and a milk-draining portion connected in sequence, the milk-draining portion forming a milk-suction channel 11. The flared portion is flared in shape. In this embodiment, a plurality of vibrating elements 3 may be specifically disposed at the end of the flared portion away from the milk-draining portion.

[0064] In some embodiments, combined with Figure 2 The breast pump 10 also includes a milk reservoir 4, which is detachably connected to the side of the main unit 2 away from the breast shield 1 along the axial direction Y of the housing 21 and communicates with the breast pump channel 11 for storing breast milk collected from the breast shield 1.

[0065] Among them, combined Figure 3 The breast milk storage device 4 includes a first housing 41, a second housing 42, and a duckbill valve 43. The first housing 41 is detachably connected to the rear housing 212 of the main unit 2, and the first housing 41 and the second housing 42 cooperate to form a breast milk storage chamber. The breast milk storage chamber is connected to the breast pumping channel 11 and is used to store breast milk collected from the breast pump 1. The duckbill valve 43 communicates with the breast milk storage chamber and is configured to communicate with a baby bottle so that breast milk in the breast milk storage chamber can be poured into the baby bottle through the duckbill valve 43.

[0066] As described above, by setting up a breast milk storage container 4 that is independent of the main unit 2 and the breast shield 1, the first shield 1a can be disassembled and cleaned separately during the cleaning process without affecting the main unit 2 and the breast milk storage container 4. At the same time, when it is necessary to pour out the breast milk in the breast milk storage container 4, the breast milk storage container 4 can also be detached from the main unit 2 and connected to a baby bottle to facilitate the pouring out of the breast milk in the breast milk storage container 4.

[0067] In some embodiments, the breast pump 10 further includes a temperature detection element (not shown), which is disposed within the housing 21 and configured to detect the temperature value of the heating unit 22. A controller is electrically connected to the temperature detection element and, in response to the temperature value reaching a preset value, controls the heating unit 22 to stop heating or controls the heating unit 22 to maintain its current operating parameters. The preset value can be set according to actual conditions. Operating parameters include heating power.

[0068] The breast pump 10 provided in this embodiment includes a breast shield 1, a main unit 2, and a power supply unit. The main unit 2 includes a housing 21 and a heating unit 22 disposed within the housing 21. The breast shield 1 is disposed on the housing 21, and the heating unit 22 is connected to the breast shield 1 for heating the breast shield 1. The power supply unit is disposed within the housing 21 corresponding to the heating unit 22 and supplies power to the heating unit 22; wherein, the power supply unit is charged via wireless charging. The heating unit 22 is configured to heat the housing 21, thereby realizing the heat therapy function of the breast pump 10. At the same time, by disposing of the heating unit 22 on the main unit 2, this breast pump reduces the risk of damaging the heating unit 22 during the process of washing or boiling the breast shield 1; and it also reduces the risk of poor power supply and malfunction of the heating unit 22 due to repeated installation and reassembly of the breast shield 1 and the main unit 2. Furthermore, by placing the power supply unit that powers the heating unit 22 inside the housing 21 and charging it wirelessly, there is no need to have a charging interface on the outside of the main unit 2. This reduces the risk that the breast pump 10 may fail to charge due to water or milk entering the charging interface, thereby further reducing the risk that the heating unit 22 may not heat up properly. Moreover, placing the heating unit 22 on the main unit 2 simplifies the manufacturing process of the breast pump, as the main unit 2 typically does not require repeated cleaning or processes such as gluing the heating unit 22. This results in a higher production yield and lower cost.

[0069] Of course, in some other embodiments, another type of breast pump 10 can be provided, which differs from any of the above-mentioned breast pumps 10 in that the breast pump cover 1 and the breast collection cover cooperate to form a milk storage container 4, and the breast pump cover 1 and the breast collection cover enclose a milk storage cavity. The main unit 2 is located inside or within the milk storage cavity. The breast pump cover 1 and the breast collection cover can be connected by means of snaps, threads, or other connection methods. To ensure the sealing of the connection between the breast pump cover 1 and the breast collection cover, a sealing element, such as a sealing ring, can be further provided between the breast pump cover 1 and the breast collection cover.

[0070] In one embodiment, a breast pump assembly is also provided, which includes the breast pump provided in any of the above embodiments and a wireless charging socket. The breast pump is mounted on the wireless charging socket to wirelessly charge the power supply unit of the breast pump 10, i.e., the power source 24. The specific structure and function of the breast pump 10 can be found in the relevant descriptions above.

[0071] The wireless charging socket includes a second circuit board and a transmitting coil connected to the second circuit board. The wireless charging socket receives a DC voltage, which generates a resonant current through the second circuit board. This resonant current is then converted into electromagnetic waves by the transmitting coil and emitted. A breast pump 10 is placed on the wireless charging socket. The receiving coil of the breast pump 10 receives the electromagnetic waves emitted by the transmitting coil and converts them into a resonant current. This resonant current is then processed by the first circuit board into a battery charging voltage, thus charging the battery.

[0072] In this embodiment, the breast pump 10 is equipped with a wireless charging socket, which charges the power supply 24 inside the breast pump 10 wirelessly. At night, when the lights are off, the user only needs to place the used breast pump 10 on the wireless charging socket to charge the breast pump 10, which brings great convenience to the user at night and helps the user to rest at night.

[0073] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
