[0035] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0036] 1A , an embodiment of the present application provides a wearable breast pump, which mainly includes a main unit component 10 and a milk bowl component 20. The milk bowl component 20 is used to be worn on the breast of a human body, and the main unit component 10 is used to provide suction force for the milk bowl component 20 to extract milk, so as to extract the milk in the breast and store it in the milk bowl component 20.

[0037] To facilitate cleaning, the main unit assembly 10 and the milk bowl assembly 20 of the wearable breast pump of this embodiment are detachably connected. When the milk bowl assembly 20 needs to be cleaned after use, the milk bowl assembly 20 can be separated from the main unit 20 first to prevent water from entering the electrical components on the main unit assembly 10, which is convenient and practical.

[0038] When the milk bowl assembly 20 and the main unit assembly 10 are designed to be detachable, if the milk bowl assembly 20 is installed on one end of the main unit assembly 10, or the main unit assembly 10 is installed to one end of the milk bowl assembly 20, it may cause the user to use too much force when grasping one of the main unit assembly 10 and the milk bowl assembly 20, resulting in the main unit assembly 10 and the milk bowl assembly 20 accidentally separating, causing the other part of the wearable breast pump that is not grasped to fall, causing the milk in the milk bowl assembly 20 to spill, and also causing the device to be damaged, resulting in a poor user experience.

[0039] Based on the above considerations, in combination with FIGS. 1A and 2, embodiments of the present application provide a wearable breast pump, which includes a main machine assembly 10 and a milk bowl assembly 20. The main machine assembly 10 has a first surface P facing the human body and a first surface T facing away from the human body. The first surface T of the main machine assembly 10 is formed with a receiving cavity 100 extending towards the first surface P. The milk bowl assembly 20 is embedded in the receiving cavity 100.

[0040] In the above, the first surface P refers to the surface of the main machine assembly 10 facing the human body, i.e., the right surface as shown in FIG. 1A.

[0041] By providing the receiving cavity 100 extending along the thickness direction on the side of the main machine assembly 10 facing away from the first surface P, the main machine assembly 10 can be used to surround the milk bowl assembly 20. The main machine assembly 10 can serve as the main housing of the wearable breast pump. When the milk bowl assembly 20 is installed in the receiving cavity 100 of the main machine assembly 10, the periphery of the milk bowl assembly 20 is surrounded by the main machine assembly 10. When a user operates the breast pump, the user only needs to hold the main machine assembly 10. Therefore, the milk bowl assembly 20 and the main machine assembly 10 are not easily separated, and the product can be prevented from falling accidentally or the milk from spilling out.

[0042] In an embodiment, as shown in FIG. 2, the receiving cavity 100 extends through the thickness direction of the main machine assembly 10, i.e., the receiving cavity 100 extends to the first surface P. The receiving cavity 100 inside the main machine assembly 10 is formed as a through hole. The milk bowl assembly 20 is integrated with a milk bowl 21 and a milk collecting cover 22, which are installed as a whole in the main machine assembly 10.

[0043] Specifically, the milk bowl assembly 20 includes the milk bowl 21 and the milk collecting cover 22. The milk collecting cover 22 is connected to the inner surface of the milk bowl 21, and the milk collecting cover 22 and the milk bowl 21 enclose a milk storage space. After the milk bowl assembly 20 is installed in the main machine assembly 10, the milk bowl 21 is accommodated in the receiving cavity 100, and the milk collecting cover 22 is at least partially located in the receiving cavity 100.

[0044] In an embodiment, the side of the milk bowl 21 facing away from the first surface P is exposed outside the opening of the receiving cavity 100 of the main machine assembly 10, and the milk collecting cover 22 at least partially extends outside the receiving cavity 100 beyond the first surface P. The milk collecting cover 22 has a horn-shaped structure and forms a milk collecting passage 221 inside. When the wearable breast pump is worn on the breast of the human body, the milk collecting cover 22 covers the breast and is well attached to the human body. The nipple is located in the milk collecting passage 221, and the milk collected from the breast can flow into the milk bowl 21 along the milk collecting passage 221 for storage.

[0045] It can be understood that in other embodiments, as shown in FIG. 1B, the milk collecting cover 22 can also be completely located in the receiving cavity 100 without extending beyond the first surface P, i.e., the opening end of the milk collecting cover 22 is flush with the first surface P or has a distance from the first surface P.

[0046] By opening the accommodating cavity 100 through the thickness direction of the main assembly 10, the milk bowl 21 and the teat cup 22 are integrated on the milk bowl assembly 20, and the two can be disassembled as a whole, which is beneficial to improve the disassembly and assembly efficiency of the milk bowl 21.

[0047] It can be understood that in other embodiments, the accommodating cavity 100 can also not pass through the thickness direction of the main assembly 10, that is, the accommodating cavity 100 is still a distance from the first surface P. In this case, the teat cup 22 and the milk bowl 21 can be assembled with the main assembly 10 as separate structural members, for example, the teat cup 22 is mounted on the first surface P of the main assembly 10 from the right side of FIG. 1A, and the milk bowl 21 is mounted in the accommodating cavity 100 of the main assembly 10 from the left side of FIG. 1A. For another example, the milk bowl assembly 20 can also not include the teat cup 22, and the teat cup 22 is integrally connected with the main assembly 10, the first surface P is located on the teat cup 22, and the accommodating cavity 100 is the space on the left side of the teat cup 22, which is in communication with the teat cup 22 when the milk bowl assembly 20 is mounted on the main assembly 10. For another example, the milk bowl assembly 20 and the main assembly 10 can also include a part of the teat cup 22, respectively, and when the milk bowl assembly 20 is mounted in the accommodating cavity 100 of the main assembly 10, the two parts of the teat cup 22 are spliced into a complete teat cup 22. In order to facilitate the description of the present application, the following will be described with the embodiment in which the accommodating cavity 100 passes through the thickness direction of the main assembly 10.

[0048] In combination with FIG. 3, in an embodiment, the milk bowl assembly 20 further includes a deformable suction bowl 23, which is arranged on one end of the inner surface of the teat cup 22 facing the milk bowl 21, and the suction bowl 23 is used to shrink and deform under the negative pressure of the main assembly 10 to transmit the negative pressure.

[0049] In this embodiment, the direction of the shrinkage of the suction bowl 23 is along the direction of approaching or moving away from the human body, and the breast pump can be made thinner, for example, the suction bowl 23 can be located on the center line X of the teat cup 22, so that the suction bowl 23 is opposite to one end of the teat collection channel 221.

[0050] By setting the direction of the shrinkage of the suction bowl 23 as the direction of approaching or moving away from the human body, after the suction bowl 23 is deformed to generate negative pressure, the milk can be sucked into the teat cup 22 from the human body, and the milk can enter the milk storage space 200 between the milk bowl 21 and the teat cup 22 along the transverse teat collection channel 221 in the teat cup 22.

[0051] In this embodiment, the suction bowl 23 and the milk bowl 21 form a negative pressure chamber Q therebetween, the suction bowl 23 separates the negative pressure chamber Q of the milk bowl 21 from the breast shield 22, and the suction bowl 23 forms a milk inflow path and the negative pressure chamber Q on the left and right sides thereof. In this way, the suction bowl 23 can be driven to shrink into the negative pressure chamber Q by vacuumizing the negative pressure chamber Q by the main assembly 10, so as to generate a suction force acting on the breast.

[0052] Specifically, the breast shield 22 has a milk collection channel 221 and a milk outlet 22B, and the suction bowl 23 covers the milk collection channel 221 and the milk outlet 22B. The suction bowl 23 and the breast shield 22 form a gap G that communicates the milk collection channel 221 and the milk outlet 22B. As shown in FIG. 3, the milk outlet 22B is configured to be below the milk collection channel 221 during the milk collection process. The end of the milk collection channel 221 close to the suction bowl 23 can be appropriately inclined downward, so that the milk can flow naturally into the gap G between the suction bowl 23 and the breast shield 22 along the inclined milk collection channel 221 in the breast shield 22, and then flow into the storage space 200 through the milk outlet 22B for storage. The milk outlet 22B can be provided with a one-way valve K, such as a duckbill valve, to realize one-way passage of the milk and prevent the milk from flowing back from the storage space 200 to the milk collection channel 221.

[0053] In one embodiment, the suction bowl 23 and the milk bowl 21 form a negative pressure chamber Q therebetween; the main assembly 10 can specifically include a pump body 11 communicating with the negative pressure chamber Q and a battery 12 electrically connected to the pump body 11. The pump body 11 is configured to be below the milk bowl assembly 20 during the milk collection process to vacuumize the negative pressure chamber Q. The battery 12 is electrically connected to the pump body 11 to provide power for the pump body 11. The battery 12 can be disposed together with the pump body 11 below the milk bowl assembly 20.

[0054] Of course, in other embodiments, the battery 12 can also be disposed together with the pump body 11 above, or on the left or right side of the milk bowl assembly 20, as long as the battery 12 is electrically connected to the pump body 11. Alternatively, in some embodiments, the battery 12 can be omitted, and the pump body 11 can be powered by an external power source.

[0055] As shown in FIG. 3, the milk bowl 21 includes a first interface 210 that communicates with the negative pressure chamber Q and faces the pump body 11. The pump body 11 is configured to be below the milk bowl assembly 20 during the milk collection process and communicates with the first interface 210. Exemplarily, the pump body 11 communicates with a second interface 110 exposed to the inner wall of the accommodating cavity 100 of the main assembly 10. When the milk bowl assembly 20 is installed to the main assembly 10, the first interface 210 and the second interface 110 are in communication, so that the negative pressure chamber Q can be vacuumized by the pump body 11.

[0056] In one embodiment, a three-way structure (not shown in the figure) is arranged between the pump body 11 and the negative pressure chamber Q, a first end of the three-way structure is connected to the pump body 11, a second end is connected to the second interface 110, and a third end is connected to the electromagnetic valve. The three-way structure is selectively communicated with the external atmosphere through the electromagnetic valve to achieve pressure relief after the negative pressure chamber Q is vacuumized.

[0057] Optionally, the milk outlet 22B can be arranged at a lower part of the milk storage space 200, that is, the milk outlet 22B is located between the milk collection channel 221 and the pump body 11, which can facilitate the natural flow of milk.

[0058] In order to realize the installation and positioning of the suction bowl 23, the inner surface of the milk collection cover 22 towards the milk bowl 21 is formed with a flared first mounting sleeve 22C, and the suction bowl 23 is arranged in the negative pressure chamber Q surrounded by the first mounting sleeve 22C and the milk bowl 21.

[0059] Further, the milk bowl 21 can also be formed with a second mounting sleeve 21B, and the first mounting sleeve 22C and the second mounting sleeve 21B surround the negative pressure chamber Q. For example, the second mounting sleeve 21B is protruded on the inner surface of the milk bowl 21, and the edge of the suction bowl 23 is clamped between the first mounting sleeve 22C and the second mounting sleeve 21B.

[0060] The inner diameter of the first mounting sleeve 22C is larger than the outer diameter of the second mounting sleeve 21B. By using the cooperation of the first mounting sleeve 22C and the second mounting sleeve 21B, the second mounting sleeve 21B abuts the suction bowl 23 on the stepped surface of the flared portion of the first mounting sleeve 22C, which can avoid loosening of the suction bowl 23, and the first mounting sleeve 22C provides a support surface for the suction bowl 23. At the same time, the inner wall of the first mounting sleeve 22C cooperates with the outer wall of the second mounting sleeve 21B to clamp the folded edge of the edge of the suction bowl 23 therebetween, thereby providing a reliable sealing effect.

[0061] It can be understood that the edge of the suction bowl 23 clamped between the first mounting sleeve 22C and the second mounting sleeve 21B refers to the position of the edge of the suction bowl 23, and does not mean that the edge of the suction bowl 23 is fixed in this way. Optionally, the suction bowl 23 can be fixed on the first mounting sleeve 22C, or can be sleeved and fixed on the outer edge of the second mounting sleeve 21B, or can be fixed on both the first mounting sleeve 22C and the second mounting sleeve 21B. That is, the suction bowl 23 can be fixed on the milk bowl 21 to surround the negative pressure chamber Q with the second mounting sleeve 21B of the milk bowl 21, and then assembled with the milk collection cover 22; the suction bowl 23 can also be fixed on the milk collection cover 22, and when the milk bowl 21 is assembled with the milk collection cover 22, the suction bowl 23 is combined with the milk bowl 21 to surround the negative pressure chamber Q.

[0062] In combination with Figs. 2-4, the milk bowl 21 of the present embodiment comprises a top portion 211 and a ring portion 212, the top portion 211 is connected to the ring portion 212 at an end away from the first face P, when the milk bowl assembly 20 is installed to the main machine assembly 10, the milk bowl 21 is accommodated in the accommodating cavity 100, the top portion 211 of the milk bowl 21 is exposed outside the main machine assembly 10, and the ring portion 212 of the milk bowl 21 is inserted into the accommodating cavity 100 and abuts against the inner wall of the accommodating cavity 100, thereby realizing the assembly of the milk bowl assembly 20 and the main machine assembly 10.

[0063] In one embodiment, the top portion 211 of the milk bowl 21 is curved, the top portion 211 is further away from the first face P than the ring portion 212, and the ring portion 212 is connected to the inner surface of the top portion 211. Exemplarily, the top portion 211 can be arranged to smoothly transition with the main machine assembly 10, and when the milk bowl assembly 20 is installed to the main machine assembly 10, the milk bowl 21 seamlessly connects with the outer contour of the main machine assembly 10, for example, the wearable breast pump can be substantially hemispherical, realizing a more aesthetic effect.

[0064] Exemplarily, the inner peripheral wall of the accommodating cavity 100 can be perpendicular to the first face P, and the ring portion 212 is also perpendicular to the first face P, and the milk bowl assembly 20 can be loaded into the accommodating cavity 100 from the side of the main machine assembly 10 away from the first face P.

[0065] In order to limit the depth of the milk bowl assembly 20 loaded into the accommodating cavity 100 of the main machine assembly 10, as shown in Fig. 2, the outer wall of the ring portion 212 is provided with a guide rib 213 extending in the thickness direction of the main machine assembly 10, and the inner wall of the accommodating cavity 100 is provided with a U-shaped limiting groove 101, the guide rib 213 is inserted into the limiting groove 101 and abuts against the end of the limiting groove 101, and the limiting groove 101 limits the extreme position of the guide rib 213 inserted, thereby limiting the depth of the milk bowl 21 loaded into the accommodating cavity 100.

[0066] It can be understood that in other embodiments, the limiting groove 101 can also be arranged on the outer wall of the ring portion 212, and the guide rib 213 can be arranged on the inner wall of the accommodating cavity 100, that is, one of the outer wall of the ring portion 212 and the inner wall of the accommodating cavity 100 is provided with the guide rib 213 extending in the thickness direction of the main machine assembly 10, and the other is provided with the limiting groove 101, and the guide rib 213 is inserted into the limiting groove 101 and abuts against the end of the limiting groove 101.

[0067] In addition, the edge of the top portion 211 can also be provided with a flange 213 protruding outwardly from the ring portion 212, and the flange 213 abuts against the main machine assembly 10, which can also be used to limit the depth of the milk bowl 21 loaded into the accommodating cavity 100.
