The suction cup 120 and the bra 110 are integrally formed, the bra 110 cooperates with the milk cup 150, the bra 110, the suction cup 120 and the milk cup 150 together enclose a breathing cavity 170, the suction mechanism 160 is connected to the breathing cavity 170, the suction mechanism 160 is used to extract the air in the breathing cavity 170, so that a negative pressure is formed in the breathing cavity 170, so that the suction cup 120 is elastically deformed, and when the suction mechanism 160 stops working, the suction cup 120 will rebound and reset under the action of its own elastic force, and suck the outside air into the breathing cavity 170. The milk bowl 150 and the bra 110 together form a storage cavity 180. The suction bowl 120 is used to be elastically deformed under the suction of the suction mechanism 160, so as to form a negative pressure in the bra 110 and suck out the milk. The bra 110 is connected to the storage cavity 180 through a one-way flow guide 130. The one-way flow guide 130 is used to allow milk to flow into the storage cavity 180. The one-way flow guide 130 is also used to prevent the milk in the storage cavity 180 from flowing back. In this way, since the suction bowl 120 and the bra 110 are integrally formed, the number of parts is reduced, so the disassembly and assembly process of the wearable breast pump 100 is effectively simplified, the disassembly and assembly efficiency is improved, and it is convenient to assemble and suck milk and disassemble and clean.

[0036] The bra 110 includes an integrally formed connecting ring 111 and a fitting cup 112. The suction cup 120 is disposed at one end of the connecting ring 111 away from the fitting cup 112 and is integrally formed with the connecting ring 111. The bra 110 and the suction cup 120 are made of flexible materials.

[0037] In an optional embodiment, the one-way flow guide 130 is integrally formed with the connecting ring 111 and is disposed between the suction bowl 120 and the fitting cup 112.

[0038] In this embodiment, the one-way flow guide 130 is a one-way valve. In other embodiments of the present invention, the one-way flow guide 130 may also be a one-way valve or other structure with one-way transmission capability, and the specific structure type is not limited.

[0039] Preferably, the outer wall of the connecting ring 111 is provided with a sealing boss 116, and the milk bowl 150 is provided with a sealing groove 151, which is annular, and the sealing boss 116 cooperates with the sealing groove 151 to seal the breathing cavity 170, prevent air leakage, and ensure the airtightness of the breathing cavity 170. In addition, the sealing boss 116 and the sealing groove 151 cooperate to play a limiting role, so as to fix the relative position of the connecting ring 111 and the milk bowl 150, and prevent the connecting ring 111 from being misplaced in the milk bowl 150.

[0040] It should be noted that a flange groove 117 is provided at one end of the fitting cup 112 away from the connecting ring 111, and the flange groove 117 is annular. A matching boss 152 is provided at the end of the milk bowl 150, and the matching boss 152 cooperates with the flange groove 117 to fix the relative position of the milk bowl 150 and the fitting cup 112, thereby fixing the relative position of the milk bowl 150 and the entire bra 110, thereby realizing the assembly function of the milk bowl 150 and the bra 110.

[0041] Furthermore, the fitting cup 112 is provided with a handle 118, which is used for a person to pull to release the matching state of the matching boss 152 and the flange groove 117, so as to realize the disassembly function of the milk bowl 150 and the bra 110 for easy cleaning. Specifically, the handle 118 is in the shape of a sheet or a ring, and has a small area, so as to facilitate force application and will not affect the comfort of the human body.

[0042] Preferably, the fitting cup 112 is provided with a first milk outlet groove 119, and the milk bowl 150 is provided with a second milk outlet groove 153. The first milk outlet groove 119 and the second milk outlet groove 153 together form a milk outlet 190, and the milk outlet 190 is connected to the storage cavity 180, and the milk outlet 190 is used for pouring out the milk in the storage cavity 180. Specifically, the milk outlet 190 is arranged at the top of the entire wearable breast pump 100, that is, the first milk outlet groove 119 is arranged at the top of the fitting cup 112, and the second milk outlet groove 153 is arranged at the top of the milk bowl 150, so as to ensure that the milk will not flow outward during the process of filling the storage cavity 180. After the milk is sucked, the wearable breast pump 100 is removed and turned upside down, and the milk in the storage cavity 180 can be poured out through the milk outlet 190, which is convenient and practical.

[0043] Preferably, the handle 118 and the first milk outlet groove 119 are relatively arranged at the two ends of the fitting cup 112, that is, the first milk outlet groove 119 is arranged at the top of the fitting cup 112, and the handle 118 is arranged at the bottom of the fitting cup 112. In this way, when the milk bowl 150 and the bra 110 are disassembled, one hand can pull the handle 118, and the other hand can reach into the milk outlet 190 to break the first milk outlet groove 119 and the second milk outlet groove 153 apart, which is convenient and quick.

[0044] In an optional embodiment, the suction mechanism 160 includes a housing 161 and a circuit board 162, a solenoid valve 163, an air pump 164 and an air pipe 165 installed in the housing 161.

Specifically, one end of the air pipe 165 is connected to the air pump 164, and the other end is connected to the breathing cavity 170. When the air pump 164 is started, the air pump 164 can extract the air in the breathing cavity 170 through the air pipe 165 to achieve a negative pressure milk suction function.

[0045] In an optional embodiment, the suction mechanism 160 also includes a battery 166, which is installed in the outer shell and is electrically connected to the circuit board 162, the solenoid valve 163 and the air pump 164 at the same time. The battery 166 is used to supply power to the circuit board 162, the solenoid valve 163 and the air pump 164.

[0046] In an optional embodiment, the milk bowl 150 is provided with a notch 154, and the suction mechanism 160 is installed on the milk bowl 150 and disposed in the notch 154, that is, the suction mechanism 160 is embedded in the notch 154, and the suction mechanism 160 and the milk bowl 150 are assembled into a round cover shape to improve the integrity and aesthetics of the wearable breast pump 100. Specifically, the housing 161 of the suction mechanism 160 is detachably connected to the milk bowl 150, so as to facilitate assembly for milk pumping and disassembly for cleaning.

[0047] In an optional embodiment, the milk bowl 150 and the shell 161 are both made of plastic material, which has high strength and low density, and can achieve lightweight wearable breast pump 100, facilitate disassembly and assembly, and enhance user experience.

[0048] In some embodiments, a liner 140 adapted to the bra 110 is further provided. Specifically, the liner 140 is installed in the bra 110 and is disposed on the side of the suction cup 120 away from the breathing cavity 170. The liner 140 is connected to the storage cavity 180 through the one-way flow guide 130. The liner 140 is used to fit the breast and allow the nipple to extend therein. The suction cup 120 is used to elastically deform in a direction away from the liner 140 under the suction of the suction mechanism 160, so as to form a negative pressure in the liner 140 and suck out the milk.

[0049] Furthermore, the liner 140 is installed in the connecting ring 111, and the connecting ring 111 is used to limit and fix the liner 140 to prevent the liner 140 from falling out. The fitting cup 112 is used to fit with the breast to improve air tightness and ensure that a stable negative pressure is formed in the liner 140 during milk suction.

[0050] In an optional embodiment, the one-way flow guide 130 is integrally formed with the connecting ring 111, and the lining 140 is provided with a clearance groove 142, which is in communication with the one-way flow guide 130, so that the milk sucked out of the lining 140 can flow to the storage cavity 180 through the clearance groove 142 and the one-way flow guide 130 in sequence. Specifically, the one-way flow guide 130 is arranged on the lower side wall of the connecting ring 111, that is, the bra 110, the suction cup 120 and the one-way flow guide 130 are integrally formed, so as to further reduce the number of parts, simplify the disassembly and assembly process, and improve the disassembly and assembly efficiency.

[0051] Furthermore, the bra 110, the suction cup 120 and the one-way flow guide 130 are all made of silicone material, which has a certain elasticity, can realize the milk suction function, and is comfortable. In other embodiments of the present invention, the bra 110, the suction cup 120 and the one-way flow guide 130 can also be made of other flexible materials, and the specific material type is not limited.

[0052] In an optional embodiment, the one-way flow guide 130 can also be separately provided from the bra 110 and detachably mounted on the connecting ring 111 of the bra 110; in another optional embodiment, the one-way flow guide 130 can also be mounted on the liner 140 or be integrally formed with the liner 140. In this case, the bra 110 is provided with an avoidance groove, which is connected to the one-way flow guide 130. The milk sucked out of the liner 140 can flow to the storage cavity 180 through the one-way flow guide 130 and the avoidance groove in turn.

[0053] Preferably, a guide groove 113 is provided on the inner wall of the connecting ring 111, and the guide groove 113 is extended along the axial direction of the connecting ring 111. The lining 140 is provided with a slide 143, and the slide 143 is slidably matched with the guide groove 113. The slide 143 can slide relative to the guide groove 113, and the guide groove 113 can guide and limit the slide 143 to ensure that the lining 140 can only cooperate with the connecting ring 111 along the axial direction of the connecting ring 111, thereby preventing the lining 140 from rotating relative to the connecting ring 111.

[0054] Furthermore, a slot 114 is provided on the inner wall of the connecting ring 111, and the slot 114 is annular. The inner liner 140 is provided with a platform 144, and the platform 144 is engaged with the slot 114 to fix the relative position of the connecting ring 111 and the inner liner 140, so as to prevent the inner liner 140 from accidentally falling out of the connecting ring 111. Specifically, the slot 114 is provided between the guide groove 113 and the suction bowl 120, and when the inner liner 140 slides to a preset position relative to the guide groove 113, the platform 144 is engaged with the slot 114. In this way, on the one hand, the slot 114 can limit the platform 144 to fix the relative position of the connecting ring 111 and the inner liner 140; on the other hand, since the slot 114 is annular, the cooperation between the platform 144 and the slot 114 can play a sealing role, prevent air leakage, and ensure air tightness.

[0055] Furthermore, the connecting ring 111 is provided with a step surface 115, and the guide groove 113 is provided between the card groove 114 and the step surface 115. When the lining 140 slides to a preset position relative to the guide groove 113, the lining 140 abuts against the step surface 115. At this time, the step surface 115 can limit the lining 140 to prevent the lining 140 from continuing to slide into the guide groove 113, thereby playing an anti-misalignment and limiting role.

[0056] In an optional embodiment, the liner 140 includes a liner frame 145, a liner body 146, a backstop 141, and a milk barrier 147. The liner body 146 is sleeved outside the liner frame 145, the backstop 141 and the clamping platform 144 are both arranged in the liner body 146, the clearance groove 142 is opened on the liner body 146, and the slide 143 is arranged on the liner frame 145. The liner frame 145 is used to support and position the liner body 146 to increase the structural strength of the entire liner 140 and prevent the liner 140 from being deformed by negative pressure during milk suction.

[0057] Furthermore, the anti-reverse buckle 141 is annular in shape and is used to surround the outside of the nipple and always keep in contact with the breast during use to prevent milk from flowing back outwards, thereby improving the user experience.

[0058] Preferably, the milk-isolating membrane 147 is arranged in the lining body 146, and a front cavity 148 is formed between the milk-isolating membrane 147 and the suction bowl 120. The front cavity 148 can enable the suction bowl 120 to quickly form a negative pressure during the deformation process, thereby improving the milk suction efficiency, and the milk-isolating membrane 147 can block the milk to prevent the milk from splashing onto the suction bowl 120.

[0059] Specifically, the milk-isolating membrane 147 is provided with a vent hole 149, which is connected to the front cavity 148. When the suction cup 120 is elastically deformed in a direction away from the liner 140 under the suction force of the suction mechanism 160, the volume of the front cavity 148 increases and forms a negative pressure, so that the air in the liner body 146 is sucked through the vent hole 149, thereby forming a negative pressure in the liner body 146, and then sucking out the milk.

[0060] In an optional embodiment, the strength of the liner skeleton 145 is greater than the strength of the liner body 146. Preferably, the liner body 146 is made of silicone material, and the liner skeleton 145 is made of hard silicone, plastic or metal material, which has high strength and can effectively support and position the liner body 146; the liner body 146 and the milk-isolating membrane 147 are integrally formed, and preferably, the milk-isolating membrane 147 is made of silicone material.

[0061] Specifically, during the operation of the wearable breast pump 100, the wearable breast pump 100 is firstly put on so that the bra 110 and the liner 140 are both fitted to the breast (the liner 140 is placed on the areola), and the nipple is inserted into the liner 140; then the suction mechanism 160 is started to extract the air in the breathing cavity 170, so that a negative pressure is formed in the breathing cavity 170, so that the suction cup 120 is elastically deformed in a direction away from the liner 140. At this time, since the liner 140 is closely fitted to the breast, a negative pressure is formed in the liner 140, so that milk is sucked out and the milk flows out. The milk flows downward under the action of gravity and flows into the storage cavity 180 through the one-way flow guide 130 to store the milk. During this process, due to the action of the one-way flow guide 130, the milk in the storage cavity 180 will not flow back, thereby ensuring the reliability of milk suction. When one suction is completed, the suction mechanism 160 is paused. At this time, the suction bowl 120 will rebound and reset under the action of its own elastic force, and suck the outside air into the breathing cavity 170, and the air in the liner 140 will also return to normal pressure, and no more milk will be sucked out. This cycle is repeated until the milk suction operation is completed.

[0062] The wearable breast pump 100 provided in the embodiment of the present invention comprises a bra 110 including an integrally formed connecting ring 111 and a fitting cup 112, a suction cup 120 disposed at one end of the connecting ring 111 away from the fitting cup 112 and integrally formed with the bra 110, the bra 110, the suction cup 120 and the milk bowl 150 together enclose a breathing cavity 170, the suction mechanism 160 is connected to the breathing cavity 170, the milk bowl 150 and the bra 110 together enclose a storage cavity 180, the suction cup 120 is used to elastically deform under the suction of the suction mechanism, so that negative pressure is formed in the bra 110 and milk is sucked out, and the one-way flow guide 130 is used to allow milk to flow into the storage cavity 180. Compared with the prior art, the wearable breast pump 100 provided by the present invention can simplify the disassembly and assembly process, save time and labor, improve the disassembly and assembly efficiency, facilitate assembly for milk suction and disassembly for cleaning, and improve the user experience.

[0063] Second embodiment

[0064] Please refer to Figure 7 The embodiment of the present invention provides a wearable breast pump 100. Compared with the first embodiment, the difference of this embodiment is that the suction mechanism 160 is external.

[0065] In this embodiment, the milk bowl 150 is no longer provided with a notch 154, and the suction mechanism 160 is no longer embedded in the notch 154, but is externally placed on the milk bowl 150.
