Description

Technical Field

[0001] This invention belongs to the field of maternal and infant product technology. Specifically, this invention relates to a wearable breast pump. Background Technology

[0002] Wearable breast pumps are typically used inside a bra. For example, patent application number 201510647623.2, filed on October 9, 2015, entitled "A Breast Pump Suitable for Lying Down and Hands-Free Use," describes a breast pump including a base cover, air bladder, shell, and cups. In this design, the cups are fitted over the shell, which in turn fits over the air bladder, increasing the pump's thickness. Similarly, patent application number 202122735820.3, filed on November 9, 2021, entitled "Integrated Breast Shield and Wearable Breast Pump," describes a breast pump including an integrated breast shield 100, a main unit 2, a breast shield support frame 4, and a bottle body 31. In this design, the main unit is connected to the breast shield support frame and the bottle body, while the breast shield support frame is connected to the integrated breast shield. The integrated breast shield has a supporting structure between it and the main unit, which increases the thickness of the breast pump.

[0046] Please refer to Figures 1 to 10 ,in, Figure 1 This is a schematic diagram of the structure of the wearable breast pump of the present invention.

[0047] Figure 9 This is a schematic diagram of the structure of the breast pump main unit of the present invention; Figure 10 This is a cross-sectional view of the wearable breast pump of the present invention.

[0048] like Figure 1 , Figure 2 and Figure 10 As shown, in one embodiment of the present invention, a wearable breast pump is provided. Specifically, the wearable breast pump includes a detachably connected breast pump main unit 2 and a breast pump container. The breast pump container includes a bottle 1 and a breast shield 5, with the breast shield 5 connected to the bottle 1. The breast shield 5 includes an integrally formed suction part 7, a fitting part, and a suction part. In use, the suction part 7 conforms to the breast; the fitting part connects to the breast pump main unit 2, thereby forming a sealed cavity 29 between the breast pump main unit 2 and the suction part; the suction part expands to draw milk when the sealed cavity 29 is under negative pressure.

[0049] In this embodiment, the wearable breast pump uses the breast pump main unit 2 and the breast shield 5 to form a sealed cavity 29, which saves thickness space, thereby avoiding discomfort caused by compression, and improving the fit during use, reducing air leakage and milk leakage. Furthermore, the wearable breast pump mainly consists of two parts: a washable part—the breast pump container—and a non-washable part—the breast pump main unit 2. The breast pump container includes only two components: the bottle 1 and the breast shield 5, with fewer parts and easy cleaning.

[0050] like Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, in one embodiment of the present invention, to ensure the sealing performance of the sealed cavity 29, a one-way sealing ring is provided on the end face of the mating part facing the suction part. The one-way sealing ring surrounds the outside of the suction part and can abut against the breast pump main unit 2, sealing the gap between the mating part and the breast pump main unit 2. Specifically, the one-way sealing ring includes an abutting part 26 and a suspension part 25 protruding from the end face of the suction part. The abutting part 26 is located between the suspension part 25 and the suction part. The end face of the abutting part 26 facing the breast pump main unit 2 is flat and can fit against the breast pump main unit 2. The cross-section of the suspension part 25 is an inclined triangle, and the vertex of the triangle is inclined towards the breast pump main unit 2. The side of the triangle near the mating part forms an angle with the end face of the mating part. When the abutting part 26 fits against the breast pump main unit 2, the suspension part 25 can deform under the action of extrusion force, thereby ensuring the sealing performance of the sealed cavity 29. Furthermore, in this embodiment, the suspension part 25 is tilted toward the breast pump main unit 2, thus having a one-way sealing effect when the sealed cavity 29 is closed. That is, external gas cannot enter the sealed cavity 29 through the suspension part 25, while the gas inside the sealed cavity 29 can be discharged to the outside through the suspension part 25, which is suitable for the negative pressure environment of the sealed cavity 29.

[0051] like Figure 6 and Figure 7 As shown, in one embodiment of the present invention, the mating part includes a mating base 24 integrally formed with a support ring. The support ring has a higher hardness than the mating base 24, thus providing support to the mating part and ensuring a tight seal between the mating part and the breast pump main unit 2.

[0052] Furthermore, such as Figure 4 and Figure 9 As shown, in this embodiment, a positioning groove 13 is provided on the outer circumferential surface of the support ring, and a spring positioning bead 28 is provided on the breast pump main unit 2. The spring positioning bead 28 is engaged with the positioning groove 13, thereby enabling a detachable connection between the breast pump main unit 2 and the breast pump container. Furthermore, when the spring positioning bead 28 is engaged with the positioning groove 13, the end of the mating part can press against the breast pump main unit 2, thereby causing the one-way sealing ring to press the breast pump main unit 2 tightly.

[0053] like Figure 6 As shown, in one embodiment of the present invention, the bottom of the support ring is connected to a connecting tube and a connecting cap. The support ring, connecting tube, and connecting cap are formed as a single unit (i.e., the support ring, connecting tube, and connecting cap are integral components after vulcanization; or the support ring, connecting tube, and connecting cap can be vulcanized separately and then assembled into an inseparable whole, for example, the support ring, connecting tube, and connecting cap can be ultrasonically welded together after being individually formed). This simplifies the number of parts and ensures the reliability of the connection. The base 24 has a milk leakage hole 21 at its bottom, and the connecting tube connects the milk leakage hole 21 and the connecting cap. The connecting cap is connected to the bottle 1. In use, milk flows from the milk leakage hole 21 to the connecting cap and finally into the bottle 1. In this embodiment, the support ring, connecting tube, and connecting cap are formed as a single unit, and then integrally formed with the breast pump 5, making the breast pump 5 a single component, which is more convenient for cleaning.

[0054] It is worth noting that, in this invention, "one-piece molding" means that a component is formed as an inseparable part when it is manufactured using a single material. For example, in this embodiment, the insertion ring 14 and the outer ring 12 of the support ring are directly vulcanized from rubber material, and after processing, they are a single, inseparable part. "Molded as one piece" means that two or more components made of different or the same material are formed into an inseparable part through methods such as hot melting, vulcanization, and bonding. For example, in this embodiment, the support ring, connecting tube, and connecting cap can be individually processed and then connected into a whole by ultrasonic welding. In this embodiment, the material of the support ring and the material of other parts of the breast shield 5 are two different types of rubber with different hardness. The support ring and the parts of the breast shield 5 other than the support ring are processed separately during vulcanization. After processing, the support ring is one part, and the other parts of the breast shield 5 other than the support ring are another part. The two parts are formed into an inseparable breast shield 5 through methods such as hot melting and bonding. Of course, in other embodiments of the present invention, based on considerations such as ease of processing, cost saving, and ease of maintenance, the breast shield 5 can also be made detachable. For example, the support ring, connecting tube, and connecting cover on the breast shield 5 can all be removed from the breast shield 5 for easy cleaning.

[0055] Furthermore, in this embodiment, the connecting cap includes an inner cap edge 23 and an outer cap edge 22. The inner cap edge 23 is snapped with a one-way valve 18, and the outer cap edge 22 is screwed onto the baby bottle 1. By setting the one-way valve 18, the reliability of unidirectional milk flow can be ensured; by setting the screw connection between the baby bottle 1 and the outer cap, it is convenient for the user to remove the baby bottle 1 for use; the connecting cap is provided with a vent hole 17, which can balance the air pressure inside and outside the baby bottle 1.

[0056] In one embodiment of the present invention, to ensure the reliability of the mating base 24 and the support ring being integrally formed, the mating base 24 is provided with an annular groove, and the annular groove is provided with a plurality of mating holes, which are evenly distributed on the circumference of the annular groove. The support ring is located inside the annular groove, and the support ring is provided with a plurality of mating protrusions, which are evenly distributed on the circumference of the support ring; the mating protrusions are inserted into the mating holes one by one, which can ensure that the mating base 24 and the support ring are integrally formed.

[0057] like Figure 5 and Figure 6As shown, in one embodiment of the present invention, the support ring is made of rubber, and the hardness of the support ring is greater than that of the rubber on other parts of the breast shield 5. The support ring includes an integrally formed insertion ring 14 and an extension ring 12. The extension ring 12 is located between the insertion ring 14 and the adsorption part 7, and can support the adsorption part 7 to ensure the reliability of the adsorption part 7's fit. Specifically, the extension ring 12 is coaxially arranged with the adsorption part 7, and the outline of the extension ring 12 is smaller than the outline of the adsorption part 7, which makes the central part of the adsorption part 7 harder and less prone to deformation, while the edge part is softer and easier to fit.

[0058] Furthermore, in this embodiment, the insertion ring 14 can have various shapes, such as elliptical or circular. When the insertion ring 14 is elliptical, with the major axis of the ellipse vertical and the minor axis horizontal, it ensures the correct connection between the breast shield 5 and the breast pump main unit 2, thus preventing errors. A positioning groove 13 is provided at each end along the minor axis to ensure the reliable connection between the breast shield 5 and the breast pump container. When the insertion ring 14 is circular, the two positioning grooves 13 are located at both ends of the same diameter of the circle. A circular insertion ring 14 is easier to process and shape, facilitating manufacturing and saving costs.

[0059] Furthermore, in this embodiment, the outer peripheral surface of the insertion ring 14 is provided with a draft angle, which facilitates the installation and removal of the breast shield 5 on the breast pump host 2 and ensures a sealing effect during connection.

[0060] like Figure 6 , Figure 7 and Figure 10 As shown, in one embodiment of the present invention, the suction part is connected to the abutment part 26, and at the junction of the suction part and the abutment part 26, the suction part is provided with an extension section 27 extending toward the suction part 7. When the sealed cavity 29 is under negative pressure (less than atmospheric pressure), the suction part can expand under the action of negative pressure, thereby offsetting the pressure difference between its own interior and the sealed cavity 29. When the suction part expands, the extension section 27 allows the suction part 7 to expand toward the breast pump main unit 2, thereby increasing the deformation of the suction part and ensuring the milk extraction effect.

[0061] Furthermore, in this embodiment, the extension 27 is arc-shaped, and the center of the arc is located between the extension 27 and the suction part, thereby ensuring the smoothness of the suction part during expansion and contraction, and making the deformation process of the suction part gentler.

[0062] like Figure 5 , Figure 6 and Figure 8As shown, in one embodiment of the present invention, to facilitate the expansion and contraction of the suction part, the suction part is a cavity with uniform wall thickness. Specifically, the suction part includes an integrally formed suction body 16 and a guide ridge 15 located on the circumferential surface of the suction body 16. In use, the guide ridge 15 is used to guide the deformation of the suction body 16. The guide ridge 15 has a U-shaped outline when the suction part is cut along a plane parallel to the end face of the mating part. When the air pressure inside the sealed cavity 29 is negative, the two side walls of the U-shape of the guide ridge 15 can move in opposite directions under the action of negative pressure, thereby causing the wall of the suction body 16 to expand outward and thus absorb milk. When the air pressure inside the sealed cavity 29 returns to atmospheric pressure, the two side walls of the U-shape of the guide ridge 15 can elastically recover their natural shape under normal pressure, thereby causing the wall of the suction body 16 to retract.

[0063] Furthermore, in this embodiment, the suction part is cut along a plane perpendicular to the end face of the mating part, the outline of the guide ridge 15 is arc-shaped, and the center of the arc is close to the suction body 16. The outline of the suction body 16 is arc-shaped, and the center of the arc is close to the guide ridge 15, thereby enabling control of the expansion of the suction part. During expansion, the circumference of the suction part gradually expands from the suction part 7 to the breast pump main unit 2.

[0064] Furthermore, in this embodiment, there are multiple guide ridges 15, which are symmetrically distributed on the circumferential surface of the suction body 16, enabling the suction part to expand and retract evenly on the circumferential surface. Preferably, there are four guide ridges 15, which can both promote the smooth and uniform expansion and retraction of the suction part on the circumferential surface and avoid hindering the expansion and contraction.

[0065] like Figure 2 As shown, in one embodiment of the present invention, a suspended realistic suction nozzle is also included. In use, the suspended realistic suction nozzle is used to simulate a baby sucking milk. It can conform to the areola and work with the suction part to squeeze the nipple, thereby simulating a baby sucking milk. It can also support the nipple to facilitate the flow of the sucked milk into the bottle 1.

[0066] like Figure 6 As shown, in one embodiment of the present invention, the suspended realistic suction nozzle and the breast shield 5 are integrally formed. Specifically, the suspended realistic suction nozzle includes a suction hole 19, a suspension support part 20, and a realistic contact ring 8. The suction hole 19 passes through the suspension support part 20 and the realistic contact ring 8, allowing the nipple to enter the suction part. The suspension support part 20 is supported inside the breast shield 5 and connects the breast shield 5 and the realistic contact ring 8. The realistic contact ring 8 is located on the end face of the suspension support part 20 facing away from the breast pump main unit 2, and can support the areola, so that the nipple is suspended in the suction part. In addition, when in use, if the suction part 7 of the breast shield 5 does not fit tightly with the user or is loose, the suspended realistic suction nozzle can also compensate for the air leakage caused by the lack of fit.

[0067] In another embodiment of the invention, instead of a suspended realistic suction nozzle, the breast shield 5 is provided with a realistic contact ring 8 and a suction hole 19, meaning that the realistic contact ring 8 is directly part of the breast shield 5 during molding. Specifically, the realistic contact ring 8 is located on the end face of the breast shield 5 away from the breast pump main unit 2; the suction hole 19 connects the suction part 7 and the suction part.

[0068] like Figure 2 and Figure 6 As shown, in one embodiment of the present invention, the simulated contact ring 8 is flared. Specifically, the simulated contact ring 8 is cut along a plane perpendicular to the end face of the mating part, and the outline of the simulated contact ring 8 is arc-shaped, with the center of the arc facing the breast shield 5; the simulated contact ring 8 is cut along a plane perpendicular to the end face of the mating part, and the wall thickness of the simulated contact ring 8 gradually decreases from the breast shield 5 to the free end of the simulated contact ring 8, thereby ensuring that the simulated contact ring 8 fits tightly and has moderate softness and hardness during use.

[0069] like Figure 3 As shown, in one embodiment of the present invention, the breast pump main unit 2 includes a housing and a control component, a three-way pipe 11, an air pump 10, a solenoid valve, and a power connection port 6 installed within the housing. Specifically, the control component is connected to the air pump 10 and the solenoid valve, providing operational control. One end of the three-way pipe 11 is connected to the air pump 10, one end to the solenoid valve, and one end communicates with the sealed cavity 29. During use, the air pump 10 is turned on, and the solenoid valve controls the expansion and contraction of the suction section by opening and closing. The power connection port 6 is connected to the air pump 10 and the control component, respectively, for connecting an external power supply. The control component includes a display screen 4, control buttons 3, and a controller. The controller is connected to the display screen 4, control buttons 3, air pump 10, solenoid valve, and power connection port 6, providing operational control. The control buttons 3 can adjust the parameters of the controller, and the display screen 4 can display the adjusted parameters.

[0070] Furthermore, in this embodiment, the breast pump main unit 2 also includes a battery 9, which is installed inside the housing and connected to the power port 6. This allows it to supply power even without an external power source, supporting the use of the wearable breast pump. The power port 6 is a USB Type-C interface, connected to the battery 9, which can directly supply power and charge the battery 9 when an external power source is connected.

[0071] like Figures 1 to 10 As shown below, the working process of the present invention will be described in detail:

[0072] When in use, connect the power supply, which can be powered by battery 9 or an external power source. Adjust the operating parameters of the breast pump main unit 2 using control button 3. The air pump 10 starts, and the solenoid valve opens and closes according to the preset parameters. When the solenoid valve is closed, the sealed cavity 29 forms a negative pressure under the action of the air pump 10, the suction section expands, and the simulated contact ring 8 squeezes the areola, thereby drawing out milk. When the solenoid valve opens, the sealed cavity 29 returns to atmospheric pressure, the suction section retracts, and the simulated contact ring 8 relaxes. The continuous opening and closing of the solenoid valve can simulate the scene of a baby sucking milk, and the milk drawn out enters the bottle 1 through the leak hole 21, the connecting cap, and the one-way valve 18. The one-way valve 18 is for one-way passage, allowing milk and gas to pass through but not allowing milk and gas to flow back, and can work with the solenoid valve to form a sealed environment.

[0073] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics.
