Description

Technical Field

[0001] This utility model relates to the technical field of maternal and infant products, specifically a neck-hook type breast pump. Background Technology

[0002] In modern society, breastfeeding is receiving increasing attention. For working mothers and those who need to express excess breast milk in a timely manner, breast pumps have become an indispensable tool. With the growth of market demand, there are many types of breast pumps on the market to meet the diverse needs of different consumers.

[0003] In terms of power type, breast pumps are mainly divided into manual and electric types. Manual breast pumps usually generate suction by manually pressing or pulling the device. They are relatively simple to operate and more affordable, but their milk expression efficiency is low and they can easily cause hand fatigue after prolonged use. Electric breast pumps, on the other hand, can effectively improve milk expression efficiency and reduce the burden on users due to their automated milk expression process, and are therefore favored by many consumers.

[0004] Electric breast pumps are further subdivided into single-sided and double-sided models. Single-sided electric breast pumps have a more traditional design, with the control unit located directly above the breast shield. This unit includes core components such as the air pump, solenoid valve, and control panel, used to generate and adjust suction. Below the breast shield are a one-way valve and a bottle. The one-way valve ensures milk flows directly into the bottle, preventing backflow. However, this type of single-sided breast pump has significant drawbacks. During use, the user must hold the breast pump, which greatly restricts their freedom of movement. Furthermore, because there is only one breast shield, the user can only pump milk from one breast before switching to the other, making the entire pumping process time-consuming and inefficient.

[0005] Double electric breast pumps are designed to improve milk expression efficiency. They come with two sets of breast shields and bottle components, connected by multiple silicone tubes and connectors, allowing simultaneous expression from both breasts and significantly reducing expression time. However, double electric breast pumps are not without their flaws. While some feature a wearable three-way connector, they still don't truly free the hands. Users need to place the main unit on a table or hang it around their waist, which can interfere with normal activities and housework. Even wearable breast pumps with the main unit and three-way connector integrated have several problems. The integrated design increases the overall weight and size, making it difficult for bras to secure the pump. During activity, the pump can easily shift and leak air, resulting in poor expression and still restricting the user's movement.

[0006] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0007] In response to the aforementioned technical problem that existing breast pump units are inconvenient to carry when pumping milk.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A neck-hanging breast pump includes a neck-hanging assembly. At each end of the neck-hanging assembly is an air pump component and a control component that are electrically connected. The air pump component is connected to two milk suction components. Each milk suction component includes a milk storage bowl and a breast shield disposed thereon. The milk storage bowl is provided with a vent connected to the air pump component.

[0010] A magnetic attraction energizing component is provided between the air pump component and the control component, which enables the air pump component and the control component to be electrically connected.

[0011] As described above, in a neck-hanging breast pump, the air pump component includes an air pump assembly connected to the neck-hanging assembly and a solenoid valve assembly connected to the air pump assembly. The solenoid valve assembly includes a solenoid valve housing and two solenoid valve bodies disposed therein, with each of the two solenoid valve bodies corresponding to one of the two breast pumping components.

[0012] As described above, in a neck-hanging breast pump, a connecting member is provided between the air pump assembly and the two solenoid valve bodies, and the solenoid valve housing is provided with two connecting nozzles respectively corresponding to the air vent.

[0013] As described above, in a neck-hook type breast pump, the connecting component includes a three-way pipe, each of the output ends of the solenoid valve body is provided with a two-way connector, the input end of the three-way pipe is connected to the output end of the air pump assembly, the two output ends of the three-way pipe are respectively connected to the input ends of the corresponding two-way connectors, and the output end of each two-way connector is connected to the corresponding connecting port.

[0014] As described above, the control component of a neck-hook breast pump includes an electrical housing connected to the neck-hook assembly and a control box connected to the electrical housing. The electrical housing contains a power supply battery, and the control box contains a control circuit board.

[0015] As described above, in a neck-hanging breast pump, the air pump component includes an air pump assembly connected to the neck-hanging assembly and a solenoid valve assembly connected to the air pump assembly; the control component includes an electrical housing connected to the neck-hanging assembly and a control box connected to the electrical housing; and the magnetic energizing component is disposed on the control box and the solenoid valve assembly.

[0016] As described above, the neck-hanging breast pump includes a magnetic energizing assembly comprising a power supply coil located inside the control box, a first magnet located outside the control box, an energizing coil located inside the solenoid valve assembly, and a second magnet located outside the solenoid valve assembly.

[0017] As described above, in a neck-hanging breast pump, a positioning component is provided between the first magnet and the second magnet, the positioning component including a positioning protrusion and a positioning groove.

[0018] As described above, a neck-hanging breast pump includes a main neck-hanging component, two telescopic sliding sleeves, and two telescopic components. Each telescopic sliding sleeve is located at the end of the main neck-hanging component and between the corresponding telescopic component. The main neck-hanging component is slidably connected to the telescopic sliding sleeve, and each telescopic component is slidably connected to the corresponding telescopic sliding sleeve.

[0019] As described above, the neck-hanging breast pump includes a venting section comprising a groove in the milk storage bowl, a spout in the groove, and an air tube located between and connected to the spout and the air pump component.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model relates to a neck-hanging breast pump, specifically within the technical field of maternal and infant products. It includes a neck-hanging assembly with an air pump and a control unit at each end. The air pump connects to two milk-suction components, each including a milk storage bowl and a breast shield mounted thereon. The milk storage bowl has a vent connected to the air pump. A magnetic energizing component allows for electrical connection between the air pump and the control unit. The neck-hanging design allows the breast pump to be worn around the neck, enabling free hand movement during pumping and improving ease of use. Furthermore, the magnetic energizing component utilizes magnetic attraction to quickly and accurately connect and energize the air pump and control unit, making operation simpler and more efficient. The two components can also be easily separated for storage, cleaning, or maintenance, significantly enhancing the user experience.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1 to 6 As shown, a neck-mounted breast pump according to this embodiment includes a neck-mounted assembly 1. An air pump component 2 and a control component 3 are respectively provided at both ends of the neck-mounted assembly 1. The air pump component 2 is connected to two milk suction components 4. Each milk suction component 4 includes a milk storage bowl 41 and a breast shield 42 disposed thereon. The milk storage bowl 41 has a vent 411 connected to the air pump component 2. A magnetic attraction and energizing component 6 is provided between the air pump component 2 and the control component 3, enabling the air pump component 2 and the control component 3 to be electrically connected.

[0031] Specifically, control unit 3 can control the operation of the entire breast pump, such as adjusting the pumping mode (e.g., different suction strengths, frequencies, etc.) and switching the device on and off. The commands issued by control unit 3 are transmitted to air pump unit 2 via electrical connection.

[0032] After receiving the instruction from the control unit 3, the air pump component 2 starts to work. The air pump generates negative pressure, which is transmitted to the breast shield 42 through the channel connected to the vent 411 on the milk storage bowl 41 of the milk suction component 4. The breast shield 42 fits against the mother's breast and simulates the sucking action of an infant under the action of negative pressure, sucking the breast milk from the breast. The sucked breast milk flows through the breast shield 42 into the milk storage bowl 41 for storage.

[0033] Furthermore, the breast pump adopts a neck-hook design, and the neck-hook component 1 in this embodiment is deformable and can be adjusted according to the shape of the user's neck, making it convenient to wear around the neck. Compared with traditional breast pumps that need to be placed on a table or hung on the waist, this neck-hook design does not affect the user's hand movements. The user can freely carry out other daily activities during the breast pumping process, such as reading, working, taking care of children, etc., which greatly improves the convenience of use.

[0034] Furthermore, the neckband component 1 can fit snugly against the human neck, and the air pump component 2 and control component 3 are respectively located at both ends of the neckband component 1, making the overall weight distribution of the breast pump more even, reducing the burden on the body in certain areas, and making it less likely to feel fatigued after long-term use. This layout makes the overall structure of the breast pump more compact. At the same time, the magnetic power-conducting component 6 achieves electrical connection, which not only ensures the stability of the connection, but also facilitates disassembly and assembly, making it easy to carry and store.

[0035] Since the air pump component 2 is connected to two milk suction components 4, it can achieve simultaneous milk suction from both breasts, improving milk suction efficiency; or it can be adjusted by the control component 3 according to the user's needs to achieve milk suction from one side.

[0036] Each component (such as neckband assembly 1, air pump assembly 2, control assembly 3, breast pump assembly 4, etc.) is relatively independent. If a component malfunctions, it is easy to repair or replace it individually, reducing maintenance costs and difficulty.

[0037] Moreover, compared to wearable breast pumps which are prone to shifting and leaking air, neck-mounted breast pumps are secured by hanging around the neck, making them more stable during activities and less likely to shift, thus ensuring normal breast pumping.

[0038] The above design also makes it easier for users to operate the control component 3 to adjust the suction power, mode and other parameters of the breast pump. It also facilitates the connection and gas transmission between the air pump component 2 and the breast pump component 4, making the overall structure design more scientific and reasonable.

[0039] Furthermore, the magnetic power-on component utilizes the principle of magnetic attraction to enable the air pump component 2 and the control component 3 to connect quickly and accurately. When using the breast pump, the user only needs to bring the two components close together, and they will automatically align under the action of magnetism, completing the connection and enabling power-on. Unlike traditional plug-in interfaces, there is no need to carefully align the pins, making the operation simpler and more efficient. When storing or cleaning or repairing the components, the two components can be easily separated and the power can be turned off, saving time and effort.

[0040] Since the magnetic connection does not require complicated plugging and unplugging actions, users can connect and disconnect the air pump component 2 and the control component 3 with one hand. This is very practical for mothers during the breast pumping process, because in many cases they may only have one hand free. The convenience of one-handed operation greatly improves the user experience.

[0041] like Figures 1 to 6 As shown, the air pump component 2 in this embodiment includes an air pump component 21 connected to the neck hanging component 1 and a solenoid valve component 22 connected to the air pump component 21. The solenoid valve component 22 includes a solenoid valve housing 221 and two solenoid valve bodies 222 disposed therein. The two solenoid valve bodies 222 correspond one-to-one with the two milk suction components 4.

[0042] Specifically, the air pump assembly 21 is started under the control of the control unit 3, and begins to operate and generate suction. The air pump assembly 21 is like the power source of the entire breast pump. By operating, it draws out air and creates a negative pressure environment in the system to provide power for milk expression.

[0043] The suction force generated by the air pump assembly 21 is transmitted to the two solenoid valve bodies 222 in the solenoid valve assembly 22 through the connecting member 5. Each solenoid valve body 222 corresponds to a milk suction component 4. The control component 3 can independently control the opening and closing of each solenoid valve body 222.

[0044] Preferably, the control component 3 can open two solenoid valve bodies 222 at the same time, so that the suction force generated by the air pump assembly 21 will act on the two milk suction components 4 at the same time, so as to realize milk suction from both breasts at the same time.

[0045] Preferably, the control component 3 can also open only one of the solenoid valve bodies 222, in which case only the corresponding milk suction component 4 generates suction force to perform unilateral milk suction operation.

[0046] like Figures 1 to 6 As shown, in this embodiment, a connecting member 5 is provided between the air pump assembly 21 and the two solenoid valve bodies 222. The solenoid valve housing 221 is provided with two connecting nozzles 223 that correspond to the air vent 411 respectively, so that the breast pump can operate through a single pump and dual valve control mode.

[0047] When the solenoid valve body 222 is opened, the suction force generated by the air pump assembly 21 is transmitted to the air vent 411 of the milk suction component 4 through the corresponding connector 223, thereby causing the milk suction component 4 to generate suction force to perform milk suction operation; when the solenoid valve body 222 is closed, the corresponding milk suction component 4 stops milk suction.

[0048] The single-pump dual-valve design requires only one air pump assembly 21 to provide suction for both breast pumping components 4. Compared to using two air pumps to power the two breast pumping components separately, this reduces energy consumption, lowers production and operating costs, and also reduces the overall weight of the breast pump, improving portability.

[0049] Users can flexibly choose between bilateral or unilateral breast pumping modes according to their actual needs. When there is a lot of milk or when it is desired to empty the breast quickly, choosing the bilateral breast pumping mode can greatly shorten the pumping time and improve the pumping efficiency. When there is less milk on one breast or when it is necessary to pump milk from only one breast, the unilateral breast pumping mode can be selected to meet personalized pumping needs.

[0050] Each breast pump component 4 is controlled by an independent solenoid valve body 222, which means that the suction power of the two breast pump components 4 can be adjusted independently without interference. Even if one breast pump component has a problem, such as air leakage or blockage, it will not affect the normal operation of the other breast pump component, thus ensuring the stability and reliability of the breast pump.

[0051] With precise control of the solenoid valve body 222, the suction strength and frequency of each milk-suction component 4 can be adjusted more accurately to simulate the rhythm of a baby's sucking, making the milk-suction process more comfortable and also helping to increase the amount of milk secreted.

[0052] like Figures 1 to 6 As shown, the connecting component 5 in this embodiment includes a three-way pipe. Each output end of the solenoid valve body 222 is provided with a two-way plug 224. The input end of the three-way pipe is connected to the output end of the air pump assembly 21. The two output ends of the three-way pipe are respectively connected to the input ends of the corresponding two-way plugs 224. The output end of each two-way plug 224 is connected to the corresponding connecting nozzle 223.

[0053] Specifically, after the air pump assembly 21 is started, it begins to work, drawing out air to generate suction. This suction is output from the output end of the air pump assembly 21 and enters the input end of the connected three-way pipe. The three-way pipe acts as a distributor, splitting the single suction flow generated by the air pump assembly 21 into two streams that flow to its two output ends respectively.

[0054] The two output ends of the three-way pipe are connected to the input ends of the corresponding two-way plugs 224. The two distributed suction flows enter the solenoid valve body 222 through the two-way plugs 224. At this time, the solenoid valve body 222 is opened or closed according to actual needs under the action of the control component.

[0055] When the solenoid valve body 222 is opened, the suction force is transmitted from the output end of the two-way plug 224 to the corresponding connector 223, and then from the connector 223 to the corresponding milk suction component 4, so that the milk suction component 4 generates suction force and thus realizes the function of milk suction. If the solenoid valve body 222 is closed, the suction force cannot be transmitted to the milk suction component 4 through this passage, and the milk suction component 4 stops working.

[0056] The combination of a three-way pipe and a two-way connector results in a simple overall structure that does not require complex pipe layouts or connections. This simple structure makes the entire air circuit system more compact, reduces the space occupied inside the breast pump, facilitates the miniaturization of the breast pump, improves the product's portability, and makes it convenient for users to carry and use.

[0057] Compared to some complex multi-channel dispensing devices, three-way pipes and two-way connectors are relatively common and low-cost components. Using them to construct the connecting component 5 can effectively reduce the production cost of the breast pump, making it more price-competitive in the market and affordable for more users.

[0058] The three-way pipe can distribute the suction force generated by the air pump assembly 21 to the two solenoid valve bodies 222 relatively evenly, ensuring that the suction force obtained by the two milk suction components 4 is basically the same. In this way, in the bilateral milk suction mode, the suction force on both breasts is the same, which is conducive to the even discharge of milk from both breasts and improves the effect and efficiency of milk suction.

[0059] The structures of the three-way pipe and the two-way plug are relatively independent. When one of the components is damaged or malfunctions, it is easy to disassemble, repair and replace it separately. This not only reduces maintenance costs, but also shortens maintenance time, improves product maintainability and reduces the inconvenience caused to users by equipment failure.

[0060] Preferably, the two-way plug 224 in this embodiment is L-shaped.

[0061] Specifically, in the entire air circuit system of the breast pump, the suction generated by the air pump assembly is distributed through the three-way pipe and enters the two-way connector 224. Since the two-way connector 224 is L-shaped, it can change the airflow direction within a limited internal space. When the airflow enters one end of the two-way connector 224 from the three-way pipe, the L-shaped structure guides the airflow to turn in a vertical direction, so that it can be smoothly connected to the solenoid valve body and connecting nozzle, etc., ensuring that the suction can be transmitted to the milk pumping component according to the preset path to realize the milk pumping function.

[0062] The L-shaped design allows the two-way connector 224 to better utilize space for fixing and installation when connected to other components. When connected to the three-way pipe, solenoid valve body 222, and connector 223, the L-shaped shape can provide multiple contact points and support surfaces, enhancing the stability of the connection, reducing loosening of the connection due to vibration or external force, ensuring the air circuit system's sealing, and enabling continuous and stable transmission of suction.

[0063] Modern breast pumps typically prioritize miniaturization and portability, resulting in limited internal space. The L-shaped two-way connector 224 is better suited to this compact layout. It allows for airway connection and diversion without significantly increasing horizontal or vertical space usage, enabling the internal components of the breast pump to be arranged more closely. This helps reduce the overall size of the product, making it easier for users to carry and use.

[0064] Inside the breast pump, the various components need to be arranged in a reasonable manner to achieve optimal function. The L-shaped two-way connector can flexibly bypass other components and avoid interference with other structures, thereby optimizing the utilization of internal space and improving the integration of the product.

[0065] Furthermore, because the L-shaped structure has a certain directionality and positioning function, it is easier to accurately align the interfaces of other components during installation, reducing problems such as loose connections or air leaks caused by improper installation, and improving the quality and reliability of the product.

[0066] Furthermore, when airflow flows in the air passage, the L-shaped two-way connector can play a certain buffering role. During the turning process, the speed and direction of the airflow will change. This change can reduce the direct impact of the airflow on the ventilation parts, reduce the risk of component damage or loosening of connections caused by airflow impact, and extend the service life of the air passage system.

[0067] like Figures 1 to 6 As shown, the control component 3 in this embodiment includes an electrical housing 31 connected to the neckband assembly 1 and a control box 32 connected to the electrical housing 31. The electrical housing 31 is provided with a power supply battery 33, and the control box 32 is provided with a control circuit board.

[0068] Specifically, the power supply battery 33 is installed inside the electrical housing 31 and serves as the power source for the entire breast pump. The battery 33 stores electrical energy and outputs it to the control box 32 where the control circuit board is located. The power supply battery generally has a stable voltage output capability to ensure that it provides appropriate power to the control circuit board and other related components, and maintains the normal operation of the breast pump.

[0069] Preferably, the control circuit board inside the control box 32 is the "brain" of the breast pump. It receives electrical energy from the power supply battery 33 and distributes and regulates the electrical energy according to the user's operation instructions (such as adjusting the suction strength, milk pumping mode, etc.). The control circuit board precisely controls the working state of the air pump component 2 through preset programs and algorithms, thereby realizing different milk pumping functions. For example, when the user selects a specific suction level, the control circuit board will adjust the current or voltage output to the air pump component 2 so that the air pump generates a corresponding suction strength.

[0070] Preferably, the power supply battery 33 and the control circuit board are respectively housed in the electrical housing 31 and the control box 32, forming a modular structure. This design makes it easy for users to operate and replace different components individually. If the power supply battery 33 is low on power, the user can easily charge or replace the battery. If the control circuit board malfunctions, the control box 32 can be repaired or replaced separately without replacing the entire control component 3, thus reducing the cost of use and the difficulty of maintenance.

[0071] Preferably, the power supply battery 33 is encapsulated in the electrical housing 31. This independent encapsulation design can effectively protect the battery from external factors such as impact, compression and moisture, reducing the risk of short circuits, leakage and other safety accidents. At the same time, the electrical housing 31 can be made of insulating material, further improving the safety of use.

[0072] Preferably, the control box 32 provides a relatively enclosed and stable working environment for the control circuit board. The control box 32 can prevent dust, moisture, and interference, protecting the control circuit board from damage by external factors and extending its service life. In addition, the control circuit board itself can also be equipped with a variety of protection mechanisms, such as overcurrent protection and overvoltage protection, to ensure that the breast pump operates in a safe state.

[0073] Furthermore, placing the power supply battery 33 and the control circuit board in different components facilitates heat dissipation. The battery generates heat during charging and discharging, and the control circuit board also generates heat during operation. Separating them can prevent heat from accumulating, improve heat dissipation efficiency, and ensure that each component operates in a suitable temperature environment, thereby improving the performance and stability of the breast pump.

[0074] Furthermore, the modular design simplifies maintenance. When the battery or control circuit board needs inspection, repair, or replacement, technicians can quickly locate and operate the corresponding component, reducing repair time and costs. This design also facilitates upgrades and improvements to the breast pump; for example, new functions can be implemented by replacing the control circuit board.

[0075] Preferably, in this embodiment, a first connecting line 34 is provided between the electrical housing 31 and the control box 32. The first connecting line 34 may be a component such as a wire, a flexible wire, or a rigid wire.

[0076] The electrical housing 31 and the control box 32 are connected by a first connecting line 34, which makes the spatial layout of these two components more flexible. Since the connecting line has a certain length, the electrical housing 31 and the control box 32 can be reasonably arranged according to the overall design of the product and the needs of use. For example, in a neck-hanging breast pump, the electrical housing 31 can be designed on one side of the neck-hanging component, while the control box 32 can be designed in a position that is more convenient for users to operate. The connection between the two is achieved through the first connecting line 34, which improves the ease of use and ergonomic design of the product.

[0077] Different users may have different postures and habits when using a breast pump. The use of the first connecting line 34 allows the electrical housing 31 and the control box 32 to move relatively independently to adapt to different usage scenarios. For example, when a user is sitting, standing or lying down while pumping, they can adjust the position of the electrical housing 31 and the control box 32 according to their own comfort without affecting the electrical connection between them.

[0078] Preferably, in some embodiments, the first connecting line 34 can be designed to make the electrical housing 31 and the control box 32 detachably connected. During product assembly, it is only necessary to connect both ends of the first connecting line 34 to the corresponding interfaces on the electrical housing 31 and the control box 32 respectively, without the need for complex wiring and fixing operations. This not only improves production efficiency but also reduces production costs. If a component in the electrical housing 31 or the control box 32 malfunctions, the two components can be easily separated for individual repair or replacement through the connection method of the first connecting line 34. The faulty component can be handled simply by disconnecting the first connecting line 34 without affecting the normal use of other components.

[0079] Preferably, the first connecting wire 34 can be made of different types of wire materials, such as conductors, flexible wires or rigid wires, according to specific usage requirements.

[0080] For example, wires have good conductivity and are suitable for power transmission, enabling direct electrical connection between the power supply battery 33 inside the electrical housing 31 and the control circuit board inside the control box 32.

[0081] For example, a flexible cord has good flexibility, is easy to bend and arrange, and is suitable for use in situations where space is limited or frequent movement is required. The power supply battery 33 and the control circuit board can be electrically connected by laying wires or other electrical connectors inside the flexible cord.

[0082] For example, rigid wires have high mechanical strength and stability, making them suitable for applications where the fixation and protection of connecting wires are critical. Electrical connections between the power supply battery 33 and the control circuit board can be achieved by laying wires or other electrical connectors within the rigid wires.

[0083] By selecting appropriate wire materials, the performance and reliability of the connector can be improved, and customers can choose the appropriate design according to their actual needs.

[0084] Preferably, the connecting member 5 further includes a protective tube covering the outside of the tee pipe, and the electrical connection (such as a wire) between the air pump assembly 21 and the solenoid valve body 222 is located inside the protective tube.

[0085] Preferably, in other embodiments, the air pump assembly 21 can also be electrically connected to the power supply battery 33 through electrical connectors (such as wires) in the neckband assembly 1, and a suitable design can be selected according to actual needs.

[0086] Preferably, the control box 32 is provided with a control component 35 electrically connected to the control circuit board. The user inputs control commands to the control circuit board by operating the control component 35 (which may be a button, touch sensor, etc.). After receiving the command, the control circuit board processes it according to the preset program and transmits the processed signal to other functional components of the breast pump (such as the air pump assembly), thereby realizing the control of parameters such as the working mode and suction strength of the breast pump.

[0087] Preferably, the control component 35 is located on the control box 32, which is convenient for users to operate directly. Users can easily adjust the working parameters of the breast pump through the control component 35 without having to search for operation buttons in the complex internal structure. Moreover, the position and design of the control box 32 can be optimized according to ergonomic principles to make the operation more comfortable and natural.

[0088] like Figures 1 to 6 As shown, the air pump component 2 in this embodiment includes an air pump component 21 connected to the neck hanging component 1 and a solenoid valve component 22 connected to the air pump component 21. The control component 3 includes an electrical housing 31 connected to the neck hanging component 1 and a control box 32 connected to the electrical housing 31. The magnetic energizing component 6 is disposed on the control box 32 and the solenoid valve component 22.

[0089] Specifically, the magnetic attraction power-conducting component 6 utilizes the principle of opposite poles attracting each other. Magnets with opposite magnetic poles are respectively set on the control box 32 and the solenoid valve assembly 22. When the two are close to each other, an attraction is generated between the magnets, so that the control box 32 and the solenoid valve assembly 22 can be tightly pressed together. This attraction ensures the stability and accuracy of the connection process and guarantees that the subsequent electrical connection can be reliably carried out.

[0090] In addition to a magnet, the magnetic energizing component 6 also integrates conductive contacts. When the control box 32 and the solenoid valve component 22 are abutted by the magnetic attraction, the conductive contacts on the control box 32 and the conductive contacts on the solenoid valve component 22 are precisely connected. In this way, the control signals and power in the control component 3 can be transmitted to the air pump component 2 through these conductive contacts, realizing the electrical connection between the air pump component 2 and the control component 3. Specifically, the control component 3 can send control commands to the air pump component 2 according to a preset program to adjust the working state of the air pump component 21 (such as the speed of the air pump, start and stop, etc.) and at the same time provide power to the solenoid valve component 22 so that it can open or close the air circuit normally.

[0091] Using the magnetic power-on component 6, the user only needs to bring the control box 32 close to the solenoid valve component 22. Under the action of magnetic force, the two will automatically attract each other and complete the electrical connection. There is no need for complicated plugging and unplugging operations. This greatly improves the efficiency of equipment assembly and disassembly, and makes it convenient for users to use, maintain, carry and perform other operations on the equipment in different scenarios.

[0092] Preferably, the connection method of the magnetically attracted electrified component is simple and intuitive. Users only need to bring the two parts close together to complete the connection, which reduces the operation threshold and improves the user experience.

[0093] The magnetic attraction allows the control box 32 to be tightly pressed against the solenoid valve assembly 22, ensuring good contact between the conductive contacts. This connection method is not easily loosened or disconnected due to factors such as vibration or shaking, ensuring a stable electrical connection between the air pump component 2 and the control component 3, and ensuring the normal operation of the equipment.

[0094] The design of the magnetic attraction power-conducting component ensures precise alignment of the conductive contacts. During the manufacturing process, the positions of the magnet and the conductive contacts can be precisely set, so that the conductive contacts of the control box 32 and the solenoid valve assembly 22 can be accurately aligned when they are attracted, reducing the probability of failure due to poor contact.

[0095] Furthermore, during the connection and disconnection process of the magnetic energizing component, the conductive contacts are encased inside the component, making it difficult for users to directly contact the live contacts during operation, thus reducing the risk of electric shock.

[0096] Specifically, when the control box 32 approaches the solenoid valve assembly 22, an attraction is generated between the first magnet 61 and the second magnet 62, causing the control box 32 to fit tightly against the solenoid valve assembly 22. This magnetic attraction not only ensures the accurate alignment of the two components in space, but also provides a stable physical connection basis for subsequent power and signal transmission.

[0097] The power supply coil and the power receiving coil constitute an electromagnetic induction system. When an alternating current is applied to the power supply coil in the control box 32, an alternating magnetic field is generated around it. According to the law of electromagnetic induction, when the solenoid valve assembly 22 is close to the control box 32 and the power receiving coil is in this alternating magnetic field, an induced electromotive force is generated in the power receiving coil, which in turn generates an induced current. Through this electromagnetic induction, the power is transferred from the control box 32 to the solenoid valve assembly 22, so that the air pump component 2 and the control component 3 are electrically connected, thereby enabling the control component to control and supply power to the air pump component.

[0098] Because there are no exposed metal contacts, the magnetic energizing assembly 6 can achieve a better sealing design. This allows the equipment to be used in harsher environments, such as humid and dusty environments, reducing the risk of electrical failures caused by moisture or dust ingress and enhancing the environmental adaptability of the equipment.

[0099] By utilizing the magnetic attraction of the first magnet 61 and the second magnet 62, the user can quickly connect the control box 32 by simply bringing it close to the solenoid valve assembly 22; when separation is required, a certain external force can be applied to overcome the magnetic force to easily separate them. This operation method is simple and convenient, saves time and effort, and improves the efficiency of equipment use.

[0100] The magnetic attraction automatically aligns the control box 32 and the solenoid valve assembly 22 when they are close together, ensuring the accurate relative positions of the power supply coil and the energized coil, thereby guaranteeing the efficiency and stability of electromagnetic induction. Even if there is a slight deviation in position during the connection process, the magnetic force will adjust it to the optimal position, reducing the hassle of manual alignment.

[0101] like Figures 1 to 6 As shown, a positioning member is provided between the first magnet 61 and the second magnet 62 in this embodiment. The positioning member includes a positioning protrusion 63 and a positioning groove 64.

[0102] Specifically, when the control box 32 approaches the solenoid valve assembly 22, the magnetic attraction between the first magnet 61 and the second magnet 62 will cause them to approach each other. During this approach, the positioning protrusion 63 and the positioning groove 64 will cooperate with each other, and the positioning protrusion 63 will automatically slide into the positioning groove 64. By utilizing the shape matching relationship between the protrusion and the groove, the relative position of the control box 32 and the solenoid valve assembly 22 is precisely defined. This allows the power supply coil and the power receiving coil to be accurately aligned, ensuring that during the electromagnetic induction process, the power receiving coil can cut the alternating magnetic field generated by the power supply coil to the maximum extent, thereby efficiently generating induced electromotive force and induced current, and achieving stable power transmission.

[0103] In some cases, in addition to electrical power transmission, signal transmission may also occur between the control box 32 and the solenoid valve assembly 22. Precise positioning helps ensure accurate connection of signal transmission lines, reduces signal interference and loss, and improves the accuracy and reliability of signal transmission.

[0104] After the positioning protrusion 63 is embedded in the positioning groove 64, a mechanical locking structure is formed, which can effectively prevent the control box 32 and the solenoid valve assembly 22 from shifting relative to each other during use. Even if the equipment is subjected to certain external force vibration or impact, the positioning component can ensure that the connection position of the two is relatively fixed, maintain a good electrical connection state, and reduce the interruption of power transmission or signal transmission failure caused by displacement.

[0105] During the magnetic connection process, the positioning component can share some of the pressure generated by the magnetic force, making the stress on the ventilation parts more even. This helps reduce component damage caused by excessive local stress and extends the service life of the equipment.

[0106] The neck-hanging assembly 1 of this embodiment includes a main neck-hanging component 11, two telescopic sliding sleeves 12 and two telescopic components 13. Each telescopic sliding sleeve 12 is located between the end of the main neck-hanging component 11 and the corresponding telescopic component 13. The main neck-hanging component 11 is slidably connected to the telescopic sliding sleeve 12, and each telescopic component 13 is slidably connected to the corresponding telescopic sliding sleeve 12.

[0107] Specifically, the neckband component 1 uses a sliding connection to achieve length adjustment. Sliding pairs are formed between the main neckband component 11 and the telescopic sliding sleeve 12, and between the telescopic component 13 and the telescopic sliding sleeve 12.

[0108] When the overall length of the neckband assembly 1 needs to be adjusted, the user can stretch the telescopic member 13 to both ends or compress it to the middle. Since the telescopic member 13 is slidably connected to the telescopic sliding sleeve 12, the telescopic member 13 will slide within the telescopic sliding sleeve 12, changing its extended or retracted length. At the same time, the telescopic sliding sleeve 12 is slidably connected to the main neckband 11. When the telescopic member 13 is moved by force, the telescopic sliding sleeve 12 will also slide along the main neckband 11. Through these two levels of sliding adjustment, the total length of the neckband assembly 1 can be flexibly changed to adapt to the neck size requirements of different users.

[0109] Different users have different neck sizes. With the telescopic adjustment function, the neckband component 1 can be flexibly adjusted according to the user's actual neck size to ensure that the neckband device fits the user's neck tightly and comfortably. It will not be too tight and cause a feeling of constriction, nor too loose and cause the device to shake or slip off, which greatly improves the wearing comfort.

[0110] When not using the neck hanging device, the telescopic component 13 and the telescopic sliding sleeve 12 can be retracted to their shortest state. This greatly reduces the overall length of the neck hanging component 1 and the corresponding storage space occupied, making it easier for users to store it in small spaces such as bags and drawers without taking up too much space or causing too much burden, thus improving the portability of the product.

[0111] Preferably, in other embodiments, the neck hanging component 1 may adopt an elastic soft wire structure to realize the telescopic deformation of the neck hanging component 1, and a suitable design can be selected according to actual needs.

[0112] like Figures 1 to 6As shown, the ventilation section 411 of this embodiment includes a groove provided in the milk storage bowl 41, a spout provided in the groove, and an air pipe provided between the spout and the air pump component 2 and connected to both respectively.

[0113] Preferably, the groove can provide some protection for the spout, preventing it from being bumped or damaged by external forces. One end of the spout is connected to the internal space of the milk storage bowl 41, and the other end is connected to the air tube, thereby establishing a ventilation channel between the milk storage bowl 41 and the air tube.

[0114] The air tube connects the nozzle and the air pump component 2. When the air pump component 2 is working, it will generate air pressure changes. When the air pump component 2 inhales, it will create negative pressure inside the milk storage bowl 41 through the air tube and nozzle. When the air pump component 2 exhales, it will deliver gas into the milk storage bowl 41 and change the air pressure inside the milk storage bowl 41.

[0115] The groove design provides a clear location and space for the installation of the nozzle and air tube, making the installation process simpler and more convenient.

[0116] If the ventilation unit 411 malfunctions, such as a blocked airway or a damaged nozzle, the relatively independent and easily disassembled components allow maintenance personnel to easily inspect, replace, and clean the faulty parts, reducing maintenance costs and difficulty.

[0117] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
