The compact design of the entire device makes it easy to carry and suitable for use when out and about, freeing breastfeeding from the constraints of specific locations and increasing user freedom.
[0034] In some embodiments, both ends of the strap 6 are connected to the housing 21 so that it can be suspended around a person's neck.
[0035] In one embodiment, a connector 220 may be provided on the housing 21, and both ends of the strap 6 are connected to the connector 220. The connector 220 may be a hook or a connecting ring, etc. The strap 6 can be directly tied to the connector 220, and can be removed for cleaning or replacement when the strap 6 is damaged or dirty.
[0036] In some embodiments, the strap 6 includes a first adjusting strap 61 and a second adjusting strap 62, with a connecting structure 63 on both straps 61 and 62 to connect them. The connecting structure 63 can be a Velcro strap or a buckle. Connectors 220 can be provided on both sides of the housing, with the fixed ends of the first adjusting strap 61 and the second adjusting strap 62 respectively connected to a connector 220. The controller 2 can be connected to the neck or arm of a person via the first adjusting strap 61 and the second adjusting strap 62. The strap 6 can be adjusted according to the individual's neck or arm size to ensure that it is neither too tight nor too loose, increasing wearing comfort.
[0037] In one embodiment, a breathable pad 210 is provided on the upper or lower surface of the housing 21. During use, the side with the breathable pad 210 is placed against the human body to improve comfort. The breathable pad 210 can be adhered to the housing 21 or connected to the housing 21 by other connection methods.
[0038] In some embodiments, the housing 21 is further provided with a wearing structure 7 for wearing the controller 2 on clothing. The wearing structure 7 can be a clip, a hook, or a pin. By connecting the device to clothing through the wearing structure 7 without direct contact with the human body, the comfort of use is improved.
[0039] In some embodiments, the suction assembly 5 includes an air pump 51, a solenoid valve 52, a control circuit board 53, and a battery 54. The input end of the solenoid valve 52 is connected to an air pipe connector 91 via an air pipe, and the output end of the solenoid valve 52 is connected to the input end of the air pump 51 via an air pipe. The controller 2 is also provided with a control switch 55 for controlling the operation of the air pump 51 and the solenoid valve 52, and the housing 21 is also provided with a charging port 56 for charging the battery 54. The air pump 51 can draw air from the milk suction unit 1 to create negative pressure and extract milk. The air pump 51 and the solenoid valve 52 are connected to the control circuit board 53, the control circuit board 53 is connected to the battery 54, and the charging port 56 is connected to the battery 54.
[0040] In some embodiments, the air pump 51 described above can be a piezoelectric ceramic pump, which reduces weight and noise compared to other air pumps. Of course, other types of air pumps can also be used.
[0041] In some embodiments, the milk suction device 1 further includes a milk storage chamber 8. A guide member 20 is provided between the milk suction cavity 3 and the milk storage chamber 8 to drain milk from the milk suction cavity 3 into the milk storage chamber 8. The upper part of the milk suction device 1 has a milk discharge port 30 communicating with the milk storage chamber 8. The output end of the guide member 20 is a narrowed opening. The guide member 20 has a certain anti-backflow effect.
[0042] In use, when the air pump 51 draws air from the air pressure chamber 4, a negative pressure is created in the air pressure chamber 4. The flexible diaphragm 10 deforms under the external pressure, reducing the space of the air pressure chamber 4. Milk is drawn out and flows into the milk suction cavity 3, and then along the guide 20 into the milk storage cavity 8 for storage. When the solenoid valve 52 blocks the air pump 51 from drawing air, the air pressure chamber 4 draws in outside air, the internal and external pressures become equal, the flexible diaphragm 10 returns to its original shape, and milk suction ends. This cycle continues until one milk suction cycle is completed. After the cycle, the milk is poured out from the milk outlet 30. The flexible diaphragm 10 can be made of breathable silicone, or other materials.
[0043] In some embodiments, the breast pump 1 includes a bra 11 and an outer cover 12 connected to the outside of the bra 11. The air pressure chamber 4 and the milk storage chamber 8 are both located between the outer cover 12 and the bra 11. The milk suction cavity 3 is located at the front end of the bra 11. The bra 11 and the outer cover 12 can be a single integrated structure or separate structures connected together by a connecting structure. The bra 11 can be made of silicone or other materials. This design supports both integrated and separate structures, allowing users to choose the most suitable style according to their needs. For components requiring frequent cleaning, the separate design is more convenient.
[0044] In some embodiments, the outer cover 12 has an opening 121 at its front end and a first annular tube 122 on its rear inner wall. The bra 11 includes a second annular tube 112 that can be inserted into the first annular tube 122 to connect the bra 11 to the outer cover 12. The front end of the second annular tube 112 has a blocking portion 113 for sealing the opening 121. The open end of the outer cover 12 has an outwardly extending outer edge 123. The blocking portion 113 has a snap-fit groove 114 for inserting the outer edge 123. The second annular tube 112 and the shielding part 113 are integral structures. The outer wall of the second annular tube 112 can be provided with a first annular protrusion 1121 to increase the friction with the inner wall of the first annular tube 122, thereby restricting the second annular tube 112 from coming off. At the same time, the first annular protrusion 1121 also has a certain sealing effect. Furthermore, the inner wall of the first annular tube 122 can also be provided with a first slot for it to be inserted at the position corresponding to the first annular protrusion 1121, so that the connection is tighter.
[0045] In some embodiments, a pull ring or handle 1130 is provided on the outer edge of the shielding portion 113 to facilitate the removal of the breast pump 1.
[0046] In some embodiments, the bra 11 includes a frame 1312 to enhance its strength. The frame 1312 can be an injection-molded part or a metal part. The frame 1312 provides additional support, ensuring the bra 11 maintains its shape during use and avoids deformation, especially during breastfeeding, as the negative pressure during breastfeeding can cause the bra 11 to deform, affecting the breastfeeding effect. The frame 1312 can significantly enhance the overall structural strength of the bra 11, extending the product's lifespan. The design of the frame 1312 can be adjusted according to different needs; for example, the injection-molded part can be designed into a more complex shape to accommodate different breast shapes.
[0047] In some embodiments, a cover 9 that can open the air pressure chamber 4 is detachably connected to the outer cover 12, thereby facilitating disassembly and cleaning. The cover 9 is provided with an air pipe connector 91 that communicates with the air pressure chamber 4, and the air pipe connector 91 is connected to the solenoid valve 52 through an air pipe. The cover 9 can be connected to the outer cover 12 by a snap-fit, or it can be connected to the cover 9 by an interference fit or other connection structure.
[0048] In some embodiments, there are two milk suction devices 1, which correspond to the two breasts of a human body. There are two solenoid valves 52, one solenoid valve 52 controls one milk suction device 1, and the output ends of the two solenoid valves 52 are connected to the input end of the air pump 51 through a three-way valve. The output end of the air pump 51 discharges gas to the outside.
[0049] The two breast pumps 1 are each controlled by an independent solenoid valve 52, enabling simultaneous pumping from both breasts, mimicking a baby's natural sucking action and improving pumping efficiency. The operating modes of the two solenoid valves 52 can be adjusted to flexibly switch between single-sided and double-sided pumping, meeting different needs. Simultaneous pumping from both sides significantly shortens the total pumping time, increases efficiency, and reduces the burden on the mother. The combined design of the two solenoid valves 52 and the air pump 51 ensures stable system operation; even if one solenoid valve 52 fails, the other can continue operating, providing a backup solution. Through a three-way connection, the air pump 51 can centrally manage gas flow, ensuring the overall reliability of the system. The separately controlled breast pumps 1 reduce the risk of cross-contamination, ensuring an independent and clean pumping environment for each breast.
[0050] This utility model provides a wearable breast pump device, including a breast pump 1 that fits snugly against the breast and a controller 2 that controls the breast pump 1 to pump milk. The breast pump 1 has a breast pump cavity 3 on one side and an air pressure chamber 4 inside. A flexible diaphragm 10 separates the breast pump cavity 3 and the air pressure chamber 4. The controller 2 includes a housing 21 and an air extraction component 5 disposed within the housing 21 that draws gas from the air pressure chamber 4 to create a negative pressure. The housing 21 has a strap 6 for wearing the controller 2 on the body. This allows users to wear the breast pump device around their neck, collar, or arm, enabling them to perform other activities while pumping milk, greatly improving convenience and flexibility. The device allows for quick and easy adjustment of the controller's position, enhancing the user experience. The compact design of the entire device makes it easy to carry and suitable for use when out and about, freeing breastfeeding from specific locations and increasing user freedom.
