Description

Technical Field

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

[0002] Wearable breast pumps are becoming increasingly popular among breastfeeding women, freeing up their hands and allowing for safer and more hygienic temporary collection of excess breast milk. Existing wearable breast pumps include a milk collection cup, a retaining plate covering the opening of the milk collection cup, a detachably connected housing assembly covering the opening of the milk collection cup, and a breast shield mounted on the front of the housing assembly. The retaining plate includes a plate covering the milk collection cup, a milk inlet penetrating the plate and communicating with the milk collection cup, a one-way valve covering the milk inlet, an air-filled cup extending upwards from the plate and surrounding the milk inlet, an elastic air bladder housed within the air-filled cup, and a connecting tube penetrating the front of the air-filled cup and extending axially perpendicular to the air-filled cup to the opening of the milk collection cup. The housing assembly seals the air-filled cup, and the breast shield includes a trumpet-shaped cup and a milk tube extending from the bottom of the cup, the milk tube and the connecting tube forming a detachable, sealed connection. When using the breast pump, the cups are placed over the breasts. The entire breast pump is supported by the bra. The air pump in the shell assembly draws air from the elastic air bladder, creating negative pressure in the air cup. This negative pressure then forms in the connecting tube and milk duct, drawing the milk into the air cup and allowing it to flow into the milk collection cup, thus achieving the purpose of convenient milk collection.

[0003] However, in wearable breast pumps using this technology, both the milk collection cup and the housing are made of rigid materials, such as hard plastic. To achieve a tight and sealed connection, the rigid materials make disassembly for cleaning inconvenient. They are difficult to open, and repeated forceful disassembly and reassembly can cause the latches to loosen, resulting in a poor seal and unreliable performance.

[0004] Therefore, it is necessary to provide a new wearable breast pump to solve the above problems. Utility Model Content

[0030] The following descriptions of the embodiments are with reference to the accompanying drawings, illustrating specific embodiments in which the present invention can be implemented. Directional terms used in this invention, such as up, down, front, back, left, right, inside, outside, side, etc., are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and understanding of the present invention, and not for limiting the present invention.

[0031] Please refer to Figure 1-4 As shown, this utility model provides a wearable breast pump 100, including a milk collection cup 1, a stabilizing plate 2, a sealing ring 3, a breast shield 4, an outer shell assembly 5, and an elastic airbag 6.

[0032] The milk collection cup 1 is made of a rigid material, such as rigid food-grade plastic.

[0033] The stabilizing plate 2 includes a plate body 21 that covers the open end of the milk collection cup 1 and whose periphery is detachably connected to the milk collection cup 1; a milk inlet 22 that passes through the plate body 21 and communicates with the milk collection cup 1; a one-way valve 23 that covers the milk inlet 22; an air groove cup 24 that extends upward from the plate body 21 and surrounds the milk inlet 22; a connecting pipe 25 that passes through the front of the air groove cup 24 and extends along an axial direction perpendicular to the air groove cup 24 to the open end of the milk collection cup 1; a hook 26 that extends downward from the outer periphery of the plate body 21; and an exhaust hole 27 that communicates the milk collection cup 1 with the outside.

[0034] In this embodiment, "front" refers to the side of the wearable breast pump 100 facing the breast when the user uses it.

[0035] The plate 21, the air trough cup 24, and the connecting pipe 25 are all made of rigid materials, such as rigid plastic.

[0036] There are many ways to set the hook 26, as long as it is suitable for installing the sealing ring 3. In this embodiment, the hook 26 includes an annular hook wall 28 extending downward from the outer periphery of the plate 21 and a hook tip 29 formed by bending outward from the bottom end of the hook wall 28. The stabilizing plate 2 also includes an annular top wall 20 extending horizontally outward from the end of the hook wall 28 away from the hook tip 29. The width of the top wall 20 is greater than the width of the hook tip 29, that is, the end of the top wall 20 away from the hook wall 28 is further away from the hook wall 28 than the end of the hook tip 29 away from the hook wall 28. The hook tip 29, the hook wall 28, and the top wall 20 together form a receiving groove. The sealing ring 3 is at least partially received in the receiving groove.

[0037] More preferably, the stabilizing plate 2 also includes a milk pouring hole 201 penetrating the plate body 21 and a plug 202 covering the milk pouring hole 201. One end of the plug 202 is fixed to the plate body 21, and the other end is inserted into the milk pouring hole 201, so that the milk collection cup 1 can pour out and store the milk after collecting it.

[0038] The sealing ring 3 is sleeved on the outer periphery of the plate 21 and wraps around the hook 26 to form a detachable fixed connection. The sealing ring 3 is made of elastic material and abuts against the inner periphery of the milk collection cup 1 to form an interference fit. Thus, the sealing ring 3 enables a detachable fixed and sealed connection between the stabilizing plate 2 and the milk collection cup 1. Moreover, because the sealing ring 3 is made of elastic material, it is compressed and contracted when it forms an interference fit with the milk collection cup 1, allowing the milk collection cup 1 to be stably fixed to the stabilizing plate 2. When disassembling and cleaning the milk collection cup 1, it can be easily disassembled by applying downward pulling force, and installed and fixed by applying upward pushing force. The disassembly and installation are highly convenient, and repeated disassembly and installation will not cause deformation or loosening of the milk collection cup 1 and the plate 21 of the stabilizing plate 2, resulting in good reliability.

[0039] In this embodiment, the sealing ring 3 is made of silicone, such as food-grade silicone, or food-grade rubber, etc., which are all acceptable.

[0040] Specifically, in this embodiment, the sealing ring 3 includes a ring body 31 that is housed in the receiving groove and whose two ends abut against the top wall 20 and the hook tip 29, respectively; a ring tongue 32 that protrudes from the outer side of the ring body 31 and abuts against the inner circumference of the milk collection cup 1; and a edging wall 33 that extends from the bottom end of the ring body 31 along the outer circumference of the hook 26. The edging wall 33 and the ring body 31 together wrap the hook. The sealing ring 3 of the above-described structure is fixed within the receiving groove by the ring body 31 itself, forming the first locking structure. Simultaneously, the edge wall 33 extends from the ring body 31 along the outer periphery of the hook 26, so that the edge wall 33 and the ring body 31 together enclose the hook 26, forming a U-shaped sleeve. This makes installation, disassembly, and cleaning more convenient. After being fitted, the hook tip 29 engages, preventing the sealing ring 3 from easily falling off the hook 26, further strengthening the fixing strength between the sealing ring 3 and the hook 26. Even after repeated disassembly and reassembly of the milk collection cup 1, the sealing ring 3 structure remains stable, resulting in better reliability in fixing and sealing the milk collection cup 1, and a longer service life. In this embodiment, the hook 26 can be a single ring-shaped or C-shaped integral structure, or multiple individual hooks spaced apart; all are feasible. In this embodiment, the hook tip 29 of the hook 26 can be an inverted T-shape, L-shape, J-shape, etc., with no shape limitation, capable of fixing any shape of the sealing ring 3.

[0041] More preferably, the inner circumferential side of the milk collection cup 1 is recessed to form a step 11, the annular tongue 32 abuts against the bottom of the step 11, and the top wall 20 of the stabilizing plate 2 is supported by the step 11. The step 11 can be used to fix the milk collection cup 1 in a proper fixed position, making disassembly and assembly more efficient.

[0042] More preferably, the outer periphery of the top wall 20 protrudes to form a plurality of mounting protrusions 200, and the side of the step 11 is provided with a stabilizing groove corresponding to the position of the mounting protrusions 200, and the mounting protrusions 200 are engaged in the stabilizing grooves. The arrangement of the mounting protrusions 200 and the stabilizing grooves makes the milk collection cup 1 more stable after installation.

[0043] The bra 4 includes a funnel-shaped breast cup 41 located on the front of the breast cup 1 and a breast tube 42 extending axially from the bottom of the breast cup 41. The breast tube 42 is inserted into the connecting tube 25 and forms a detachable sealed connection with the connecting tube 25. In this embodiment, the outer circumference of the breast tube 42 is provided with external threads, and the inner circumference of the connecting tube 25 is provided with internal threads. The external threads and the internal threads are screwed together to form a seal. This screwed connection structure is designed for easy disassembly and assembly and has good sealing performance.

[0044] In this embodiment, the outer periphery of the milk tube 42 is recessed to form an air groove 421. Two vent holes 27 are included, each penetrating the upper and lower sides of the connecting tube 25 respectively. One vent hole 27 communicates with the milk collection cup 1, and the other vent hole 27 communicates with the outside. The connecting tube 25 and the air groove 421 together form an annular venting channel, and both vent holes 27 communicate with this venting channel. The two vent holes 27 and the venting channel work together to expel excess air from the milk collection cup 1 after it has collected the milk, ensuring continuous and reliable milk collection.

[0045] The nipple cup 41 is trumpet-shaped, conforming to the breast's shape. Made of elastic material, it better matches and conforms to the breast, improving comfort. When the nipple cup 41 is placed over the breast, the nipple is directly opposite the milk duct 42. When negative pressure is generated within the milk duct 42, milk is drawn out of the breast and flows through the milk duct 42 into the milk collection cup 1 for collection. Because the nipple cup 41 is made of elastic material, it adapts to the breast's position as it adjusts, providing a certain degree of dynamic adjustment and preventing milk leakage, thus improving reliability.

[0046] The outer casing assembly 5 includes an inner casing 51 that covers the opening end of the milk collection cup 1 and forms a detachably connected inner casing 51, and an air nozzle 52 that penetrates the inner casing 51. The air nozzle 52 is connected to an air pump assembly via an air pipe. The air pump assembly can be an external structure or an integral structure with the outer casing assembly 5.

[0047] In this embodiment, the power unit such as the air pump assembly and the outer shell assembly 5 are configured as an integral structure. Specifically, the outer shell assembly 5 further includes an outer shell 53 that covers the inner shell 51 and together forms a receiving space, and an air pump assembly 54 installed within the receiving space. The air pump assembly 54 is connected to the air nozzle 52 via an air pipe. The periphery of the outer shell 53 abuts against the opening end of the milk collection cup 1.

[0048] To further improve the installation efficiency of the milk collection cup 1, in this embodiment, the outer periphery of the inner shell 51 is provided with a snap-fit ​​groove 511, and the inner periphery of the milk collection cup 1 is provided with a protruding snap-fit ​​12. The snap-fit ​​12 is closer to the opening end of the milk collection cup 1 than the step 11. The snap-fit ​​12 is engaged in the snap-fit ​​groove 511, and the two form a slight interference fit for fixation. With the above structural design, there is a "click" sound when assembling and disassembling, which can strengthen the fixation and produce a certain "feel" so that the user can confirm that the installation is in place.

[0049] The elastic airbag 6 is inserted into the air reservoir 24 and completely fits and covers the end of the connecting tube 25 near the elastic airbag 6. The elastic airbag 6 is spaced apart from the milk inlet 22, and its open end forms a detachable sealed connection with the open end of the air reservoir 24, for example, through a snap-fit ​​structure. The inner shell 51 presses against the open end of the elastic airbag 6 to form a seal, and the air nozzle 52 communicates with the elastic airbag 6.

[0050] When the air pump assembly 54 draws air from the elastic air bladder 6, it compresses the elastic air bladder 6, thereby creating a negative pressure in the air cup 24. This further creates a negative pressure in the connecting tube 25 and the breast shield 4, which compresses the breast to draw milk, which then flows into the milk collection cup 1 through the air cup 24. When the air pump 231 stops drawing air, the corresponding switch valve opens, and air enters the elastic air bladder 6 from the switch valve. The elastic air bladder 6 automatically restores its elastic deformation and comes into contact with the milk inlet 22 to prevent milk from flowing back when suction stops. At this time, the milk in the air cup 24 flows into the milk collection cup 1 by gravity. The suction and stop process is repeated to complete the milk drawing action. When the air pump assembly 54 draws in air, creating negative pressure inside the air tank cup 24, the one-way valve 23 is closed. At this time, the emulsion flows to the bottom of the air tank cup 24. When the air pump assembly 54 stops drawing in air, the elastic airbag 6 returns to its original shape and adheres to the connecting pipe 25 to form a barrier, preventing the emulsion from flowing back into the connecting pipe 25 and avoiding leakage during movement. At the same time, as the negative pressure disappears, the one-way valve 23 loses its suction force, and the liquid emulsion opens the one-way valve 23 by its own gravity and flows into the milk collection cup 1.

[0051] To facilitate smoother emulsion collection, the stabilizing plate 2 further includes an emulsion collecting groove 203 extending downwards from the plate body 21 into the emulsion collecting cup 1. An air-filled cup 24 surrounds the emulsion collecting groove 203, and the emulsion inlet 22 penetrates the bottom of the groove. The one-way valve 23 is fixed to the bottom of the emulsion collecting groove 203. The design of the emulsion collecting groove 203 also allows the air-filled cup 24 to better fit with the elastic airbag 6, facilitating the drainage of emulsion within the air-filled cup 24, and also improves the fit with the one-way valve 23, increasing airtightness.

[0052] In this embodiment, the one-way valve 23 is made of an elastic material, or it can be a duckbill structure made of an elastic material.

[0053] Compared with related technologies, the wearable breast pump of this utility model includes a stabilizing plate covering the open end of the milk collection cup. A hook is formed on the outer periphery of the plate, and a ring-shaped sealing ring is provided. The sealing ring wraps around the hook to form a detachable fixed connection. The sealing ring abuts against the inner periphery of the milk collection cup to form an interference fit. This not only ensures an effective seal when the stabilizing plate is placed over the milk collection cup, but also, because the sealing ring is made of elastic material, it is compressed and contracted when forming an interference fit with the milk collection cup, allowing the milk collection cup to be stably fixed to the stabilizing plate. When disassembling and cleaning the milk collection cup, it can be easily disassembled by applying downward pulling force, and easily installed and fixed by applying upward pushing force. The disassembly and installation are highly convenient, and repeated disassembly and installation will not cause deformation or loosening of the milk collection cup and the plate, resulting in good reliability.

[0054] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
