Alternatively, in one example, multiple vibration motors 121 are scattered about the center of flange 112, enabling simultaneous or rotating vibration massage of multiple points on the user's breasts, promoting blood circulation and removing blood stasis, unclogging the mammary ducts, and further improving milk ejection efficiency.

[0094] In one example, the vibration motor 121 has an arc-shaped cross-section, which better conforms to the user's breasts and increases the therapeutic area of ​​a single vibration motor 121, further improving milk ejection efficiency. Multiple vibration motors 121 are arranged at intervals along the circumference of the flange 112, providing simultaneous or rotating vibration massage at multiple points on the user's breasts, promoting blood circulation and removing blood stasis, unblocking mammary ducts, and further improving milk ejection efficiency.

[0095] In another example, the vibration motor 121 has a circular cross-section, which can better fit the user's breasts, further increasing the treatment area of ​​a single vibration motor 121, and thereby improving milk ejection efficiency. The circular shape of the annular vibration motor 121 coincides with the center of the flange 112, aiming to provide a uniform vibration massage to the user's breasts. The presence of multiple vibration motors 121 allows for a multi-ring simultaneous or multi-ring rotation vibration massage effect on the user's breasts, better fitting the user's breasts, further increasing the treatment area of ​​a single vibration motor 121, and thereby improving milk ejection efficiency.

[0096] In one embodiment of the present application, as shown in Figures 1 and 15, the vibration motor 121 protrudes from the surface of the main unit 30 facing the breast shield 11.

The side walls of the groove 113 are sleeved around at least a portion of the structure of the vibration motor 121. The side of the flange 112 that is close to the breast is a flat surface.

[0097] In this embodiment, the vibration motor 121 is exposed on the surface of the main unit 30 facing the breast shield 11. The vibration motor 121 is partially accommodated within the groove 113 provided on the flange 112, indirectly vibrating and massaging the user's breasts. This prevents the vibration motor 121 from generating rigid impacts that could damage the user's skin. The bottom and walls of the groove 113 are made of a flexible material. The bottom and walls of the groove 113 can be abutted against the bottom of the groove 113, allowing the side walls of the groove 113 to fit over the outer peripheral walls of the portion of the vibration motor 121 that is in contact with the bottom. The flexible material of the bottom and walls of the groove 113 effectively prevents the vibration motor 121 from affecting other parts of the flange 112 when in motion. The vibration of the vibration motor 121 is transmitted to the breasts through the groove 113, resulting in greater efficiency and a better massage effect.

[0098] In one embodiment of the present application, referring to FIG. 2 and FIG. 18 , the flange 112 includes a flange body 1122 , and the groove 113 is integrally formed or detachably fixed to the flange body 1122 .

[0099] In this embodiment, the groove 113 and the flange body 1122 can be integrally formed, which facilitates processing and eliminates the need for secondary assembly. The vibration motor 121 can be directly inserted into the groove 113. It is understood that the groove 113 and the flange body 1122 can also be connected in a detachable manner, such as a snap connection, to facilitate the removal of a single groove 113 and the replacement or repair of the corresponding vibration motor 121.

[0100] The flange body 1122 is connected to the groove 113 with a flexible fold. This design effectively prevents the vibration motor 121 from affecting the main body of the flange body 1122 when in motion. The side of the groove 113 facing the vibration motor 121 is provided with a first sleeve groove. The groove opening of the first sleeve groove is flared, and the vibration motor 121 is positioned within the first sleeve groove. This facilitates assembly of the vibration motor 121 into the first sleeve groove.

[0101] The vibration motor 121 can include an elastic cap and a vibration motor. The elastic cap is installed in the mounting cavity and extends out of the through-hole. The elastic cap has a second socket groove, and the vibration motor is nested in the second socket groove. This arrangement allows the vibration motor 121 to provide a vibration massage to the user, promoting blood circulation and removing blood stasis, unblocking mammary ducts, and improving milk ejection efficiency. Furthermore, when the vibration motor vibrates, the elastic cap prevents rigid impact between the vibration motor and the through-hole wall, thereby preventing abnormal noise and component wear.

[0102] The elastic cap can be installed in various ways within the mounting cavity. A brim is provided around the end of the elastic cap located within the mounting cavity, bonded to the cavity wall. A cap band is formed around the end of the elastic cap near the mounting cavity, and an assembly ring is provided around the through-hole in the cavity wall. The cap band fits over the assembly ring. This arrangement eliminates the need for additional materials and equipment, allowing for manual installation, resulting in highly efficient and convenient installation.

[0103] Limiting ribs are set on the periphery of the assembly ring, and limiting notches are set correspondingly on the cap hoop. The limiting ribs cooperate with the limiting notches. In this way, the limiting ribs can not only limit the cap hoop to avoid the problem of guide twisting and knotting of the vibration motor caused by the rotation of the elastic cap, but also play a role in strengthening the structural strength.

[0104] The circumferential side of the elastic cap is spaced apart from the hole wall of the through hole, so that when the vibration motor vibrates, fatigue deformation caused by repeated squeezing of the circumferential side of the elastic cap and the hole wall can be avoided.

[0105] In one embodiment of the present application, the flange body 1122 is made of a rigid material, and the groove 113 is at least partially made of a flexible material and is integrally formed on the flange body 1122; alternatively, the flange body 1122 and the groove 113 are integrally formed and are both made of flexible or semi-flexible materials.

[0106] In this embodiment, flange body 1122 is made of a rigid material, such as plastic, and groove 113 is at least partially made of a flexible material, such as silicone or rubber. Vibration motor 121 transmits vibrations to the breast through groove 113, which is at least partially made of flexible material, thereby improving vibration efficiency. Of course, in other embodiments, flange body 1122 and groove 113 are both made of flexible or semi-flexible materials, such as rubber or silicone, and flange body 1122 and groove 113 are integrally formed for ease of production and processing. Vibration motor 121 transmits vibrations to the breast through groove 113 and flange body 1122, thereby improving vibration efficiency.

[0107] In one example, the therapy unit 12 may also include a massage component that massages the user's breasts to promote blood circulation, remove blood stasis, unclog the mammary ducts, and further improve milk ejection efficiency. The massage component may be a ball-type massage component or a cam-type massage component, both of which can massage the user's breasts, unclog the mammary ducts, and improve milk ejection efficiency. It is understood that the massage component may also be a combination of the above two massage components, capable of simultaneously or in batches to provide different effects on the user's breasts, further improving milk ejection efficiency.

[0108] In another example, the physiotherapy unit 12 also includes a hot compress component, which applies hot compress to the user's breasts to achieve a physiotherapy effect, promote metabolism and improve microcirculation. Through local thermal stimulation, the surrounding small blood vessels are expanded to improve microcirculation, promote local metabolism, and thereby improve milk discharge efficiency.

[0109] In another example, the therapy unit 12 also includes a cold compress component that applies a cold compress to the user's breasts to relieve pain and swelling, thereby preventing inflammation. This component utilizes a semiconductor cooling chip. When energized, the chip forms a cold end and a hot end. The cold end indirectly contacts the user's breasts through the breast shield 11, achieving the cold compress therapy effect.

[0110] In one embodiment of the present application, the breast pump 100 further includes a power supply system, which is electrically connected to the negative pressure component 32 and the physical therapy structure for supplying power to the negative pressure component 32 and the physical therapy structure.

[0111] In this embodiment, the power supply system can adopt rechargeable batteries, storage batteries or power cords, etc., which are not further limited here, as long as they can supply power to the negative pressure component 32 and the physiotherapy structure to meet functional requirements.

[0112] The present invention also provides a breast pumping bra 1000. Referring to FIG. 17 , the breast pumping bra 1000 includes a bra body 200 and a breast pump 100. The bra body 200 includes shoulder straps and a housing. The breast pump 100 is the aforementioned breast pump 100, which is mounted within the housing. The breast shield 11 of the breast pump 100 is positioned to fit snugly against the breast. In this embodiment, the bra body 200 is an everyday bra. The specific shape and material should be selected based on the user's specific needs. The breast pump 100 is positioned within the housing. The support of the housing and the shoulder straps allow the breast pump 100 to fit snugly against the user's breast, freeing the user's hands.

[0113] In the prior art, the bionic baby mouth structure of a breast pump 100 generally utilizes a cavity formed between an external rigid flange 112 and an internal flexible flange 112. During negative pressure suction, the cavity creates a massage structure to massage the breast. This requires the flange 112 to cooperate with the flange 112 to form the massage structure, resulting in a relatively complex structure. The present invention provides a breast shield 11 with a simpler structure that can achieve a bionic baby mouth structure.

[0114] The present invention also provides a breast shield 11, which is used to fit the breast in a breast pumping device or a breast massage device, with reference to Figures 1, 2 and 19. The breast shield 11 includes a flange 112, a nipple accommodating portion 111 and an elastic deformation structure 1121. The flange 112 is used to fit the breast, the nipple accommodating portion 111 is used to accommodate the nipple, the flange 112 is connected to the nipple accommodating portion 111, and the elastic deformation structure 1121 is integrally formed on or detachably connected to the breast shield 11.

[0115] In this embodiment, the breast shield 11 includes a flange 112 and a nipple accommodating portion 111. The nipple accommodating portion 111 is open at both ends and is through-hole, and is used to accommodate the nipple. The material of the nipple accommodating portion 111 can be a rigid material, such as plastic, metal tube, glass tube, etc., or a flexible or semi-flexible material, such as rubber or silicone, etc., which is not specifically limited here. The flange 112 includes a flange 112 body and an elastic deformation structure 1121. The elastic deformation structure 1121 is made of a flexible material, such as rubber or silicone. When negative pressure is applied to the flange 112, the elastic deformation structure 1121 can deform, thereby massaging the user's breasts, promoting blood circulation and removing blood stasis, unblocking the mammary ducts, and further improving milk ejection efficiency. The flange 112 body and the elastic deformation structure 1121 can be integrally formed or connected by means such as gluing.

[0116] The breast shield 11 includes a flange 112, a nipple channel, and an elastically deformable structure 1121. The flange 112 is used to seal and conform to the breast. The side of the flange 112 that conforms to the breast is trumpet-shaped, allowing the flange 112 to better conform to the breast and form a sealed space between the flange 112 and the breast. The side of the flange 112 that is away from the breast has an opening, and the nipple channel communicates with the flange 112 through the opening. The nipple channel is used to accommodate the nipple. The breast forms a sealed space when it conforms to the flange 112, allowing the nipple to be located within the nipple channel. The elastically deformable structure 1121 is elastic and can be deformed and bulged toward the inside of the flange 112 under the influence of negative pressure, thereby massaging the breast and encouraging milk to flow from the breast into the nipple channel. The negative pressure system is connected to the interior of the breast shield 11 and is used to extract gas from the breast shield 11, causing the interior of the breast shield 11 to be in a negative pressure state. As a result, the elastically deformable structure 1121 is affected by the negative pressure and deforms toward the inside of the flange 112 to produce a bulge, so that the elastically deformable structure 1121 massages the breast by cooperating with the undeformed inner wall of the flange 112 through the bulge.

[0117] In one embodiment of the present application, as shown in FIG. 2 , the elastic deformation structure 1121 is provided at the connection between the flange 112 and the nipple receiving portion 111 .

[0118] In this embodiment, the elastic deformation structure 1121 is located at the connection between the flange 112 and the nipple receiving portion 111, which can massage the user's areola, promote blood circulation and remove blood stasis, dredge the ducts in the areola, and further improve the efficiency of milk discharge.

[0119] Please refer to FIG. 2 . In one embodiment of the present application, the elastic deformation structure 1121 is disposed at a position below the midline of the nipple accommodating portion 111 .

[0120] In this embodiment, in order to simulate the sucking effect of a baby, the elastic deformation structure 1121 is arranged at a position lower than the midline of the nipple accommodating portion 111. When the flange 112 fits the user's breast, the elastic deformation structure 1121 is located in the lower part of the user's breast. At this time, negative pressure is applied to the flange 112, and the elastic deformation structure 1121 will bulge, thereby simulating the effect of the peristalsis of the baby's mouth and jaw, thereby further improving the efficiency of milk discharge.

[0121] In one embodiment of the present application, there are multiple elastic deformation structures 1121, and the multiple elastic deformation structures 1121 are evenly distributed along the circumference of the flange body 1122. In this embodiment, the multiple elastic deformation structures 1121 are provided on the flange 112, and the multiple elastic deformation structures 1121 are spaced apart along the circumference of the flange body 1122, which can simultaneously massage multiple parts of the user's breasts, further improving milk discharge efficiency.

[0122] In one embodiment of the present application, the flange 112 is made of a flexible material, and the thickness of the flange body 1122 is greater than the thickness of the elastic deformation structure 1121 .

[0123] In this embodiment, the flange 112 is entirely made of a flexible material, enhancing user comfort. The flange body 1122 and the elastic deformation structure 1121 are integrally formed, enhancing durability. The thickness of the flange body 1122 is greater than that of the elastic deformation structure 1121. When negative pressure is applied to the flange 112, the deformation of the elastic deformation structure 1121 is greater than that of the flange body 1122. Consequently, the elastic deformation structure 1121 protrudes from the flange body 1122, thereby massaging the user's breasts and further improving milk ejection efficiency.

[0124] In one embodiment of the present application, the nipple receiving portion 111 is made of a rigid material.

[0125] In this embodiment, the nipple accommodating portion 111 is made of rigid material, such as plastic, metal tube, glass tube, etc. When negative pressure is applied to the flange 112, the nipple accommodating portion 111 will not be deformed due to the negative pressure, thereby causing damage to the user's nipple.

[0126] In one embodiment of the present application, with reference to FIG. 4 , the breast shield 11 further includes a diaphragm support 114 . The diaphragm support 114 is disposed on the breast shield 11 and communicates with the breast shield 11 . The pressure diaphragm 1141 is disposed on the diaphragm support 114 .

The diaphragm support 114 is connected to the breast shield 11. The negative pressure assembly 32 can indirectly apply a negative pressure effect to the breast shield 11 through the pressure diaphragm 1141, thereby realizing the deformation of the elastic deformation structure 1121 to massage the user's breasts.

[0128] The present invention also provides a milk extraction system. With reference to Figures 1, 2, 5 and 8, the milk extraction system includes a breast shield 11, a negative pressure assembly 32 and a milk storage assembly 20. The breast shield 11 is the breast shield 11 described above, and the breast shield 11 is used to fit the breast; the negative pressure assembly 32 is used to apply negative pressure to the breast shield 11 so that the elastic deformation structure 1121 bulges inward; the milk storage assembly 20 is connected to the breast shield 11 so that milk flows into the milk storage assembly 20.

[0129] The present invention further provides a breast pump 100. With reference to Figures 1 and 8, the breast pump 100 includes a main unit 30 and a milk extraction system. The main unit 30 has a receiving chamber. The milk extraction system is the milk extraction system described above. The flange 112 of the breast shield 11 is connected to one surface of the main unit 30. The milk storage assembly 20 is connected to the other surface of the main unit 30 away from the flange 112. The negative pressure assembly 32 is at least partially disposed in the receiving chamber within the main unit 30.

[0130] The present invention also provides a breast pumping bra 1000. Referring to FIG. 17 , the breast pumping bra 1000 includes a bra body 200 and a breast pump 100. The bra body 200 includes shoulder straps and a housing. The breast pump 100 is the aforementioned breast pump 100, which is mounted on the housing. The breast shield 11 of the breast pump 100 is positioned to fit against the breast. In one embodiment of the present application, the breast pump 100 is provided with a fixing portion (not shown) that is detachably connected to the bra body 200 to secure the breast pump 100 to the bra body 200.

[0131] In this embodiment, the breast pump 100 is provided with a fixing portion to achieve a detachable connection with the bra body 200. The fixing portion can be a clip or a Velcro component, which is not further limited herein, to prevent the breast pump 100 from falling off the bra body 200 during use, causing an accident.

[0132] In one embodiment of the present application, the fixing portion is a clip, and the clip is provided on the main body 30 of the breast pump 100 .

[0133] In this embodiment, a clip is used as the fixing portion, and the clip can be snapped into contact with the bra body 200, which facilitates disassembly and improves connection stability.

[0134] The present invention also provides a breast pump 100. With reference to Figure 1, the breast pump 100 includes a breast shield 11, a main unit 30 and a milk storage assembly 20. The breast shield 11 includes a flange 112 and a nipple accommodating portion 111. The flange 112 is used to fit the breast. The nipple accommodating portion 111 has openings at both ends and is connected to one end of the nipple accommodating portion 111. The main unit 30 includes a shell 31. The shell 31 has an accommodating cavity inside. The shell 31 has a through-hole in the middle. The other opening of the nipple accommodating portion 111 is passed through the through-hole. The negative pressure assembly 32 is at least partially disposed in the accommodating cavity. The negative pressure assembly 32 is used to directly or indirectly apply negative pressure to the nipple accommodating portion 111. The milk storage assembly 20 is detachably connected to the main unit 30 and is connected to the other opening of the nipple accommodating portion 111.

[0135] In this embodiment, a breast pump 100 includes a breast shield 11, a main unit 30, and a milk storage assembly 20. The housing 31 of the main unit 30 has a through-hole extending through it. The nipple receiving portion 111 of the breast shield 11 can pass through the through-hole and communicate with the milk storage assembly 20. The breast shield 11 and milk storage assembly 20 are located on opposite sides of the main unit. This integrated design reduces the size of the breast pump 100, making it easier to carry and use. The housing 31 has a receiving chamber, and a negative pressure assembly 32 is disposed within the receiving chamber. The negative pressure assembly 32 may include an air pump, a solenoid valve, and an air circuit. The air pump may be one or more of a diaphragm pump, a piezoelectric pump, or a piston pump, and the number of pumps may be one or more. The negative pressure assembly 32 may be directly connected to the breast shield 11 via the air circuit or indirectly connected to the breast shield 11 via a diaphragm or other means to apply negative pressure to the breast shield 11, causing the breast shield 11 to deform and massage the breast, thereby achieving a milk extraction effect. The extracted milk can flow through the nipple receptacle 111 into the milk storage assembly 20 for temporary storage. It is understood that in other embodiments, the negative pressure assembly 32 may also be a mechanical pump or a hydraulic pump, as long as it can drive the breast shield 11 to generate negative pressure.

[0136] In one embodiment of the present application, with reference to FIG. 4 , the breast pump 100 further includes a pressure diaphragm 1141 . The pressure diaphragm 1141 is disposed between the housing 31 and the breast shield 11 . The negative pressure assembly 32 applies negative pressure to the breast shield 11 through the pressure diaphragm 1141 .

[0137] In this embodiment, the negative pressure component 32 indirectly applies negative pressure to the breast shield 11 through the pressure diaphragm 1141 sandwiched between the shell 31 and the breast shield 11, causing the breast shield 11 to deform and massage the breast, thereby achieving the effect of milk suction. The sucked milk can flow into the milk storage component 20 through the nipple receiving portion 111 to achieve temporary storage of the milk.

[0138] In one embodiment of the present application, the pressure diaphragm 1141 is detachably sealed or self-sealed on the breast shield 11 , so that when the negative pressure assembly 32 is activated, the pressure diaphragm 1141 deforms to generate negative pressure inside the breast shield 11 .

[0139] In this embodiment, the pressure diaphragm 1141 is detachably sealed or self-sealed on the breast shield 11. The negative pressure assembly 32 applies negative pressure to the pressure diaphragm 1141, thereby indirectly applying negative pressure to the breast shield 11, thereby preventing milk from being sucked back into the pump assembly, thereby preventing problems such as milk contamination and circuit damage.

[0140] In one embodiment of the present application, as shown in FIG1 and FIG4 , a diaphragm support 114 is provided on the side of the breast shield 11 facing the main unit 30 , a pressure diaphragm 1141 is provided on the diaphragm support 114 , and the diaphragm support 114 is sealed and connected to the negative pressure assembly 32 .

[0141] In this embodiment, the breast shield 11 is provided with a diaphragm support 114, which is sealedly connected to the negative pressure assembly 32. A pressure diaphragm 1141 is provided on the diaphragm support 114. The negative pressure assembly 32 applies negative pressure to the pressure diaphragm 1141, thereby indirectly applying negative pressure to the breast shield 11. The diaphragm support 114 provides support, forming a sealed negative pressure space between the pressure diaphragm 1141 and the breast shield 11. This allows the breast shield 11 to better massage the breasts through the pressure diaphragm 1141, thereby improving milk secretion efficiency.

[0142] Please refer to Figure 4 again. In one embodiment of the present application, the diaphragm bracket 114 includes a support frame 1142, a cover body 1143 and a connecting structure 1144. The support frame 1142 is a bowl-shaped structure with openings at both ends. One opening of the support frame 1142 is connected to the breast shield 11, and the cover body 1143 covers the other opening of the support frame 1142. The pressure diaphragm 1141 is clamped between the cover body 1143 and the other opening of the support frame 1142. One end of the connecting structure 1144 is connected to and connected to the cover body 1143, and the other end is connected to the negative pressure assembly 32; a rotating connector and a snap fit are provided on the circumferential side of the cover body 1143. The rotating connector is rotatably connected to the edge of the other opening of the support frame 1142, and the snap fit is snapped to the edge of the other opening of the support frame 1142.

[0143] In this embodiment, the diaphragm support 114 is made of a hard material, such as plastic, that is not easily deformed. The diaphragm support 114 comprises a support frame 1142, a cover 1143, and a connecting structure 1144. The support frame 1142 is a bowl-shaped structure with two openings: one opening communicates with the breast shield 11, and the other opening houses the pressure diaphragm 1141. The cover 1143 covers the support frame 1142 and communicates with the negative pressure assembly 32 via the connecting structure 1144. The negative pressure assembly 32 applies negative pressure to the pressure diaphragm 1141 through the connecting structure 1144, thereby applying negative pressure to the breast shield 11. The deformation of the breast shield 11 massages the breast, improving milk extraction efficiency.

[0144] The cover 1143 and support frame 1142 are detachably connected, facilitating replacement of the pressure diaphragm 1141 should it become elastically ineffective due to repeated deformation, simplifying maintenance and installation procedures. A rotating connector is provided on one side of the cover 1143, and a snap-fit ​​member is provided on the other end. The rotating connector pivots to the support frame 1142, and the snap-fit ​​member engages with the support frame 1142, enabling quick assembly and disassembly of the cover 1143 and the support frame 1142.

[0145] In one embodiment of the present application, the pressure diaphragm 1141 is sealedly connected to the housing 31 .

[0146] In this embodiment, the pressure diaphragm 1141 is sealed to the housing 31 of the main unit 30. At the same time, a sealed space is formed between the housing 31 of the main unit 30 and the breast shield 11. The negative pressure assembly 32 applies negative pressure to the pressure diaphragm 1141, thereby squeezing the gas in the sealed space, and ultimately pushing the breast shield 11 to deform, massaging the breast and improving the efficiency of milk discharge.

[0147] In one embodiment of the present application, with reference to FIG. 6 to FIG. 8 , the center of gravity of the main unit 30 is above the axis of the nipple receiving portion 111 .

[0148] In this embodiment, the center of gravity of the main unit 30 is set above the axis of the nipple receiving portion 111. That is, when the user wears the breast pump 100, the center of the main unit 30 is located above the user's nipple, which can enable the breast to support part of the weight of the main unit 30, thereby improving stability and labor-saving effects during use.

[0149] In one embodiment of the present application, with reference to Figures 1, 5 and 6, a surface of the shell 31 of the host 30 facing the milk storage component 20 is a first inclined surface, and a surface of the milk storage component 20 facing the host 30 is a second inclined surface, and the first inclined surface and the second inclined surface are arranged in contact with each other.

[0150] In this embodiment, a surface of the shell 31 of the main unit 30 facing the milk storage component 20 is a first inclined surface, and a surface of the milk storage component 20 facing the main unit 30 is a second inclined surface. The first inclined surface and the second inclined surface are arranged in a fit manner to facilitate the installation of the milk storage component 20, and the cross-section of the milk storage component 20 is narrow at the top and wide at the bottom, so that more milk can be held in the same volume.

[0151] In one embodiment of the present application, as shown in Figure 1, the milk storage assembly 20 includes a milk bowl cover 21 and a bowl body 22. The bowl body 22 has a milk storage space with an opening. The milk bowl cover 21 covers the opening. The milk bowl cover 21 is provided with a through hole. The other end of the nipple accommodating portion 111 is connected to the bowl body 22 through the through hole to allow milk to flow into the bowl body 22.

[0152] In this embodiment, the milk bowl cover 21 and the bowl body 22 are both made of food-grade environmentally friendly materials, such as polypropylene, polyethersulfone, etc. The milk bowl cover 21 and the bowl body 22 are connected in a detachable manner, such as a snap-on manner, so that the milk bowl cover 21 and the bowl body 22 can be disassembled and cleaned after use. The nipple accommodating portion 111 passes through the through hole opened on the milk bowl cover 21 and is connected to the milk storage space of the bowl body 22. The milk can flow directly into the bowl body 22 through the nipple accommodating portion 111 and be temporarily stored in the milk storage space. It is understandable that in other embodiments, the nipple accommodating portion 111 can also be indirectly connected to the milk storage assembly 20, and the nipple accommodating portion 111 and the milk storage assembly 20 are connected by a pipeline, etc., so as to achieve the effect of storing milk.

[0153] In one embodiment of the present application, with reference to Figures 1 and 5 , a mounting sleeve 211 is provided on the milk bowl cover 21. One end of the mounting sleeve 211 is connected to the edge of the through hole. The mounting sleeve 211 is located in the milk storage space. The other end of the mounting sleeve 211 is provided with a milk flow hole. The other end of the nipple receiving portion 111 is passed through the mounting sleeve 211. A first sealing member 1111 is provided between the nipple receiving portion 111 and the mounting sleeve 211. The mounting sleeve 211 has a circumferential wall extending inward to form a flange. The other end of the nipple receiving portion 111 is provided with the first sealing member 1111. The nipple receiving portion 111 presses the first sealing member 1111 against the flange to form a seal. The first sealing member 1111 is a suction cup. In addition to its sealing function, the first sealing member 1111 also forms a locking suction force between the breast shield 11 and the milk bowl, making the two more tightly coupled.

[0154] In this embodiment, in order to improve the connection strength between the nipple accommodating portion 111 and the milk storage assembly 20, the milk bowl cover 21 extends toward the bowl body 22 at the through hole to form an assembly tube 211, and a milk flow hole is opened at one end of the assembly tube 211. The other end of the nipple accommodating portion 111 is directly passed through the assembly tube 211, and the connection is more stable. The milk passes through the nipple accommodating portion 111 and the milk flow hole and finally flows into the milk storage space.

[0155] A first sealing member 1111 is provided between the nipple accommodating portion 111 and the assembly tube 211. A circumferential sealing groove may be provided on the outer peripheral wall of the nipple accommodating portion 111. The first sealing member 1111 is provided in the sealing groove. The nipple accommodating portion 111 abuts against the first sealing member 1111 on the inner wall of the assembly tube 211 to achieve a sealing effect and prevent milk from overflowing or flowing back.

[0156] The inner wall of the assembly cylinder 211 bulges inwardly in the circumferential direction to form a flange, and the first sealing member 1111 is sandwiched between the other end surface of the nipple receiving portion 111 and the flange, thereby forming a sealing structure to prevent milk from overflowing or backflowing.

[0157] The first sealing component 1111 is a suction cup, and the suction nozzle of the suction cup should be set toward the flange. The end face of the nipple accommodating portion 111 can press the suction cup and adsorb it on the surface of the flange facing the nipple accommodating portion 111, thereby achieving a sealing effect while increasing the connection strength between the main unit 30 and the milk storage component 20, further preventing milk from overflowing or backflowing, and preventing the milk storage component 20 from falling off the main unit 30.
