[0027] In combination with the technical solutions described above, the breast pump proposed by the present invention has at least the following technical effects:

[0028] (1) Since the present application detachably connects the breast shield to the cover body, the breast shield and the milk storage container are two separate structures, which facilitates the separate operation of the breast shield after milking is completed; for example, after milking is completed, the breast shield stained with milk can be removed from the milk storage container and cleaned; then the milk outlet container containing the milk can be stored, which reduces the step of pouring the milk in the milk storage space into the milk bottle for storage in the existing breast pump, and also facilitates the cleaning of the breast shield, thereby improving the convenience of use for users.

[0029] Alternatively, you can remove the breast shield and wash it separately, and use the nipple cover to place it on the milk inlet of the milk storage container, so that the milk storage container can be used directly to feed the child.

[0030] Alternatively, remove the breast shield and wash it separately, seal the milk inlet with the seal, and store the milk in a milk storage container for later feedings when needed.

[0031] (2) The milk storage container is designed to have at least a portion of its shape adapted to the bra, so that during the milk pumping process, the bra can have a larger contact area with the milk storage container, thereby improving the overall support effect of the breast pump and the stability during milk pumping.

[0032] (3) The cover and the milk bowl are designed to be an integrally formed structure, so that the milk storage container can be discarded after a single use. When the milking is completed, there is no need to clean the milk storage container, which saves the user's usage time.

[0033] (4) The cover and the milk bowl are designed to be detachably connected by means of threaded connection, interference fit, or other methods such as snap connection, plug-in connection, or connection with a connector, so that after milking is completed, the milk bowl and the cover can be removed and the internal space of the milk storage container can be cleaned, thereby improving the convenience of cleaning the breast pump.

[0034] (5) A first nipple channel is provided on the breast shield, or a second nipple channel is provided on the cover body, or the first nipple channel and the second nipple channel are provided on the breast shield and the cover body respectively, so that the nipple can be accommodated in the first nipple channel and / or the second nipple channel during milk pumping, thereby improving the comfort during milk pumping.

[0035] (6) The cover body and the breast shield are designed to be detachably connected by means of threaded connection, interference fit, etc., so that the user can remove the breast shield for cleaning after completing milk expression.

[0036] (7) A fitting portion is provided on the cover body, and the shape of the fitting portion is designed to be compatible with the milk outlet end of the breast shield. The milk outlet end is embedded in the fitting portion and has an interference fit with the fitting portion, so that there is a larger contact area between the cover body and the breast shield, thereby improving the sealing effect between the cover body and the breast shield.

[0037] (8) By setting a one-way valve, milk is prevented from flowing from the milk inlet to the outside of the milk storage space, thus playing a one-way flow guide role.

[0038] (9) The breast shield, the cover body and the milk bowl are designed to be detachably connected in sequence along the first direction, forming a structure that is easy to assemble and disassemble. At the same time, this design reduces the bending angle, making the milk flow smoother.

[0039] (10) The negative pressure generated by the negative pressure pump acts on the diaphragm or the air bag, causing the diaphragm and the air bag to deform, thereby forming a negative pressure in the milk storage container. The arrangement of the diaphragm and the air bag isolates the milk and keeps the negative pressure component clean and safe.

[0040] (11) The diaphragm or air bag is designed to be integrally formed on the breast shield or milk bowl, thereby improving assembly efficiency and avoiding the problem of failure of sealing the internal space of the milk storage container due to assembly error of the diaphragm or air bag.

[0041] (12) By providing a nipple or a sealing plug and placing a nipple cover at the milk inlet, the user can use the milk storage container to directly feed the child after the user finishes sucking milk; or the sealing plug is used to seal the milk inlet, so that after the user finishes sucking milk, the milk storage container containing the milk can be stored separately to prevent the milk from flowing out or being contaminated.

[0042] (13) The connection structure or connection method between the milk storage container and the assembly part is designed to be the same as the connection structure or connection method between the breast shield, which can improve the applicability and compatibility of the milk storage container and facilitate the user's quick disassembly and assembly.

[0066] The present invention provides a breast pump 1 .

[0067] Combination Figures 1 to 3 As shown, in one embodiment of the present invention, a breast pump 1 comprises a breast shield 10, a milk storage container 20 and a negative pressure assembly 30; one side of the breast shield 10 is used to cover and fit the breast, and the other side is provided with a milk outlet 11; the milk storage container 20 comprises a milk bowl 21 and a cover 22, the cover 22 is covered on the milk bowl 21, and enclosed with the milk bowl 21 to form a milk storage space 23, and a milk inlet 221 connected to the milk storage space 23 is provided on the surface of the cover 22; the negative pressure assembly 30 is used to directly or indirectly apply negative pressure to the breast shield 10 or the milk storage container 20 to suck milk into the milk storage container 20; wherein the breast shield 10 and the cover 22 are detachably connected, and the milk outlet 11 is in liquid communication with the milk inlet 221.

[0068] In this embodiment, the breast pump 1 is mainly composed of three parts: a breast shield 10, a milk storage container 20 and a negative pressure assembly 30. The breast shield 10 is made of soft silicone material, and its shape is designed to be trumpet-shaped or funnel-shaped to fit the contour of the breast, so as to ensure comfort and airtightness during the milking process. One side of the breast shield 10 is in direct contact with the breast, and the other side is provided with a milk outlet 11, which is designed as a structure that is easily connected to the milk inlet 221 of the cover body 22, so as to facilitate the assembly of the breast shield 10 and the cover body 22 and the smooth flow of milk.

[0069] The cover 22 and the breast shield 10 are detachably connected, for example, by threaded connection, plug-in connection, or snap-in connection, so as to facilitate the cleaning of the breast shield 10 and the storage of the milk storage container 20. A milk inlet 221 is provided on the surface of the cover 22, and the milk inlet 221 is connected to the milk storage space 23 to receive the milk flowing out of the breast shield 10. Furthermore, the milk inlet 221 is opened in the middle of the cover 22, and the milk outlet 11 of the breast shield 10 is also opened in the middle of the shield. Therefore, after the breast shield 10 and the cover 22 are connected, and the milk inlet 221 is connected to the milk outlet 11, the center lines of the breast shield 10 and the cover 22 are overlapped, so that when the breast shield 10 is attached to the breast, the milk storage container 20 is also matched with the bra, thereby improving the convenience of the milk pumping operation. The surface of the milk storage container 20 is provided with scales, and the material of the milk bowl 21 at least at the scales is transparent or translucent, so that during the milking process, the user can judge the amount of milk by the scales.

[0070] The negative pressure assembly 30 may be composed of a main housing 31 and a negative pressure pump 32, so as to realize automatic control of the negative pressure pump 32 to generate negative pressure to complete milk suction; of course, the negative pressure assembly 30 may also be a manually pressed negative pressure structure, such as a structure in which a pressing airbag, a pressing rod and a piston cooperate to provide negative pressure during milk suction by manual pressing. The negative pressure assembly 30 and the breast shield 10 or the milk storage container 20 may be connected in a direct or indirect manner. Specifically, direct connection refers to connecting the negative pressure port of the negative pressure pump 32 directly to the internal space of the milk storage container 20 or the breast shield 10 through an air pipe to suck out the milk and store it in the milk storage container; indirect connection refers to the gas-liquid separator at the negative pressure port of the negative pressure pump 32, and indirectly transmitting the negative pressure to the milk storage container 20 or the breast shield 10 through the vibration or deformation of the gas-liquid separator to suck out the milk and store it in the milk storage container.

[0071] In addition, the negative pressure assembly 30 can be connected to the breast shield 10 or the milk storage container 20 through a hose at a certain distance, so that the negative pressure assembly 30 can be placed on a table when sucking milk, reducing the weight of the structure worn in the bra and improving the user experience; the negative pressure assembly 30 can also be directly installed on the breast shield 10 or the milk storage container 20, so that the user can control or adjust the sucking parameters of the negative pressure assembly 30. In addition, the negative pressure assembly 30 also includes a control panel, allowing the user to adjust the suction force according to personal comfort, ensuring that the sucking process is efficient and the sucking force is gentle.

[0072] In the present embodiment, since the milk storage space 23 of the breast pump 1 is formed by enclosing the milk bowl 21 and the cover body 22, and the breast shield 10 for fitting the breast is connected to the cover body 22 in a detachable manner, the breast shield 10 stained with milk can be removed from the milk storage container 20 and cleaned separately, and then the milk storage container 20 containing the milk can be stored, which reduces the step of pouring the milk in the milk storage space 23 into a milk bottle for storage in the existing breast pump 1, and also facilitates the cleaning of the breast shield 10, thereby improving the convenience of use for users.

[0073] Since the breast sizes of different users are different, or the sizes change at different stages, there is a gap between the breast and the breast shield 10, so the same type of breast shield 10 cannot meet the milking needs of different users or users at different stages. In the existing breast pump 1, since the breast shield 10 and the milk bowl 21 need to be enclosed to form a milk storage space 23, when replacing a different type of breast shield 10, the connection between the breast shield 10 and the milk bowl 21 will be affected. Therefore, the present application designs the milk storage space 23 to be formed by the milk bowl 21 and the cover 22. When the user needs to adjust the structure of the breast shield 10, since the breast shield 10 does not play the role of forming the milk storage space 23, the impact on the structure of the milk storage space 23 can be reduced, that is, the milk storage container 20 can be adapted to breast shields 10 of different sizes, so that it is convenient for users to replace different breast shields 10 according to their own needs.

[0074] In addition, when the user needs to breastfeed, the breast shield 10 stained with milk can be removed from the milk storage container 20, and the nipple 201 can be placed on the milk inlet 221 to breastfeed, and then the breast shield 10 stained with milk can be cleaned separately, and the milk in the milk storage container 20 does not need to be poured into the milk bottle, thereby improving the convenience of breastfeeding after the breast pump 1 is completed. Further, in one embodiment of the present invention, the milk storage container 20 is designed to be at least partially compatible with the bra, so that the breast pump 1 can be firmly worn in the bra. It can be understood that the design of the milk storage container 20 to be worn in the bra does not mean that the milk storage container 20 must be completely located inside the bra, but that its design can at least partially adapt to and be worn inside the bra, so the shape of the milk storage container 20 can be arc-shaped, teardrop-shaped or generally hemispherical.

[0075] In one embodiment of the present invention, the cover 22 and the milk bowl 21 can be an integrally formed structure. In this case, the milk storage container 20 is a disposable container. When milk is needed, the milk storage container 20 is connected to the breast shield 10. After milk is sucked, the milk storage container 20 is discarded. There is no need to disassemble the cover 22 and the milk bowl 21, and there is no need to clean the milk storage container, which improves the convenience of use.

[0076] In another embodiment, the cover 22 and the milk bowl 21 can also be detachably connected, such as by threaded connection, plug-in and interference fit connection, snap connection, etc., so that the user can separate the cover 22 and the milk bowl 21 and clean the inside of the milk storage container 20 after completing milk sucking.

[0077] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the breast shield 10 extends toward the direction close to the cover body 22 and forms a first nipple channel 12, one end of the first nipple channel 12 is provided with a milk outlet 11, and the first nipple channel 12 is used to accommodate a nipple.

[0078] In this embodiment, a first nipple channel 12 is designed on one side of the shield, and the channel extends from the inner side of the shield to the milk outlet 11 to form a straight channel, which can be understood as follows. Figure 2 and Figure 3 As shown, the outer peripheral wall of the breast shield 10 with the milk outlet 11 extends toward the cover body 22 to form a tubular structure with the first nipple channel 12 inside. At this time, the milk outlet 11 of the first nipple channel 12 can overlap with the milk inlet 221 of the cover body 22, or the first nipple channel 12 can be inserted into the milk inlet 221 of the cover body 22, that is, the milk inlet 221 is located on the side of the milk outlet 11 away from the milk bowl 21.

[0079] Further, such as Figure 2 As shown, the first nipple channel 12 is designed to be inclined toward the bottom of the milk bowl 21 , which further improves the convenience of milk flowing into the milk storage container 20 .

[0080] During milking, the first nipple channel 12 is used to accommodate the nipple to ensure that the milk can smoothly pass through the first nipple channel 12, the milk outlet 11, and finally flow into the milk storage container 20. The inner wall of the first nipple channel 12 is made of soft medical grade silicone material to reduce friction and discomfort to the nipple, while providing good sealing to prevent air from entering. The diameter of the first nipple channel 12 is designed to be larger than the size of most nipples to ensure the comfort of the nipple during milking.

[0081] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the cover body 22 extends in a direction away from the breast shield 10 and forms a second nipple channel 222. An end of the second nipple channel 222 away from the breast shield 10 is provided with a milk inlet 221, and the milk outlet 11 is communicated with the second nipple channel 222. The second nipple channel 222 is used to accommodate a nipple.

[0082] In this embodiment, the cover 22 extends in a direction away from the breast shield 10 to form a second nipple channel 222. Figure 2and Figure 3 As shown, the outer peripheral wall of the milk inlet 221 of the cover body 22 extends in a direction away from the breast shield 10 to form a tubular structure having a second nipple passage 222 inside. Therefore, when sucking milk, the breast fits against the breast shield 10, and the nipple passes through the milk outlet 11 of the breast shield 10 and extends into the second nipple passage 222, so as to ensure that the milk can smoothly pass through the second nipple passage 222 and the milk inlet 221, and finally flow into the milk storage container 20.

[0083] Further, such as Figure 2 As shown, the milk inlet 221 of the cover body 22 is opened at the position of the second nipple channel 222 near the bottom wall of the channel, and the second nipple channel 222 is designed to be inclined toward the bottom of the milk bowl 21, which further improves the convenience of milk flowing into the milk storage container 20. The inner wall of the second nipple channel 222 is made of soft medical grade silicone material to reduce friction and discomfort to the nipple, while providing good sealing to prevent air from entering. The diameter of the second nipple channel 222 is designed to be larger than the size of most nipples to ensure the comfort of the nipple during milk sucking. In order to ensure the connection stability between the second nipple channel 222 and the breast shield 10, an annular convex structure is designed on the inner wall of the second nipple channel 222 facing the breast shield 10, which is tightly matched with the corresponding part of the breast shield 10 to ensure that there will be no leakage during milk sucking. In addition, the annular convex structure can also buffer the negative pressure generated during milk sucking to a certain extent and protect the nipple from damage.

[0084] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the breast shield 10 extends toward the direction close to the cover body 22 and forms a first nipple channel 12, the cover body 22 extends toward the direction away from the breast shield 10 and forms a second nipple channel 222, the first nipple channel 12 and the second nipple channel 222 at least partially overlap, and the first nipple channel 12 and the second nipple channel 222 both at least partially accommodate the nipple.

[0085] In this embodiment, the specific structure of the first nipple channel 12 and the second nipple channel 222 can refer to the introduction of the above embodiment, and no further description is given here. In this embodiment, the first nipple channel 12 and the second nipple channel 222 are provided at the same time, and the inner diameter of the first nipple channel 12 is designed to be slightly smaller than the inner diameter of the second nipple channel 222, and the first nipple channel 12 is at least partially embedded in the second nipple channel 222. This structural design increases the contact area between the breast shield 10 and the cover body 22, improves the connection strength and sealing effect between the two, and prevents milk from flowing from the gap between the second nipple channel 222 and the first nipple channel 12 to the outside of the breast pump 1. At the same time, the first nipple channel 12 and the second nipple channel 222 are both inclined toward the bottom of the milk bowl 21 to improve the smoothness of the milk flowing to the milk storage container 20. A buffer structure is provided at the intersection of the first nipple channel 12 and the second nipple channel 222, and the buffer structure is made of soft silicone material, such as a silicone sealing ring, to ensure the sealing effect during the milk sucking process.

[0086] Combination Figure 3 As shown, in one embodiment of the present invention, the cover body 22 is recessed toward the milk storage space 23 to form a fitting portion 223, and the fitting portion 223 is at least partially matched with the outer shape of the breast shield 10. The fitting portion 223 is made of hard plastic, and the breast shield 10 is embedded in the fitting portion 223 and fits with the cover body 22.

[0087] In this embodiment, it can be seen from the above that the outer shape of the breast shield 10 is trumpet-shaped or funnel-shaped, so the shape of the fitting portion 223 formed by the depression on the cover body 22 is also trumpet-shaped or funnel-shaped, so that the fitting portion 223 is adapted to the outer shape of the breast shield 10. The size of the fitting portion 223 can be the same as that of the breast shield 10 so that the two fit completely, or the size of the fitting portion 223 can be designed to be smaller than the breast shield 10 so that the breast shield 10 is partially embedded in the fitting portion 223, and the breast shield 10 exposed outside the fitting portion 223 can prevent milk from entering the fitting portion 223, thereby preventing the fitting portion 223 from being contaminated with milk, reducing the workload of cleaning.

[0088] During milk pumping, since the breast shield 10 is made of a flexible material, the breast shield 10 is brought into contact with the breast to improve the comfort during milk pumping, and the cover 22 is not used to contact the breast, so the fitting portion 223 of the cover 22 is made of hard plastic, so that when one end of the breast shield 10 is embedded in the fitting portion 223, the fitting portion 223 with good structural strength can squeeze the breast shield 10, thereby achieving a close fit between the breast shield 10 and the fitting portion 223, thereby improving the sealing effect between the breast shield 10 and the cover 22. At the same time, since the fitting portion 223 has good structural strength, the user can use a greater force to embed the breast shield 10 into the fitting portion 223, so that the breast pump 1 has a higher reliability. It can be understood that the fitting portion 223 can also be made of metal or other hard materials.

[0089] The design of the fitting portion 223 increases the contact area between the cover body 22 and the breast shield 10, thereby improving the sealing effect between the cover body 22 and the breast shield 10, thereby ensuring that milk does not leak during the milk pumping process, thereby improving the practicality and hygiene of the entire breast pump 1.

[0090] Combination Figure 3 As shown, in one embodiment of the present invention, one end of the breast shield 10 having the milk outlet 11 is a milk outlet end 13 , and the milk outlet end 13 is interference fit with the fitting portion 223 of the cover body 22 .

[0091] In this embodiment, the milk outlet end 13 and the fitting portion 223 are further connected to the cover body 22 by interference fit, that is, a tight connection is achieved through slight elastic deformation. This connection method not only ensures the firmness of the connection and the sealing effect between the breast shield 10 and the cover body 22, but also facilitates the user to quickly disassemble and clean when needed.

[0092] In order to further improve the sealing effect, a series of elastic flanges are designed on the outer periphery of the milk outlet end 13 of the breast shield 10. These flanges are made of soft silicone material, which can produce elastic deformation when the user embeds the milk outlet end 13 into the fitting portion 223, and closely cooperate with the inner surface of the fitting portion 223 to form a good sealing effect. In order to further improve the stability of the connection, a locking structure is provided between the fitting portion 223 of the cover body 22 and the breast shield 10. The structure includes an annular groove and a movable locking piece. When the milk outlet end 13 is embedded in the fitting portion 223, the locking piece will automatically slide into the groove to firmly lock the breast shield 10 on the cover body 22. The locking piece is made of high-strength plastic material to ensure the reliability of the connection.

[0093] In other embodiments, the breast shield 10 and the cover body 22 may be connected by threaded connection, fastener connection, snap connection, etc. For example, in one embodiment, the outer periphery of the milk outlet end 13 of the breast shield 10 is provided with an external thread, and the inner wall of the fitting portion 223 of the cover body 22 is provided with an internal thread. The breast shield 10 is rotated to make the milk outlet end 13 and the fitting portion 223 threadedly connected. This connection method can improve the connection strength between the cover body 22 and the breast shield 10. The threaded connection between the milk outlet end 13 and the fitting portion 223 is at least partially an elastic structure, or a sealing ring is provided to ensure the sealing effect of the cover body 22 and the breast shield 10.

[0094] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the side of the cover 22 facing away from the breast shield 10 is embedded in the milk bowl 21 and has an interference fit with the milk bowl 21 .

[0095] In this embodiment, the cover 22 and the milk bowl 21 are designed to be detachably connected, so that the user can clean the inside of the milk storage space 23 after use. Specifically, the side of the cover 22 facing away from the breast shield 10 is embedded in the milk bowl 21 and connected to the milk bowl 21 by interference fit. This structural design not only ensures the structural stability of the milk storage container 20, but also makes it easy for the user to remove the cover 22 when cleaning, thereby improving the cleaning convenience of the milk storage container 20.

[0096] The realization of interference fit depends on the size matching between the cover 22 and the milk bowl 21. In order to facilitate the sealing and assembly between the cover 22 and the milk bowl 21, the present application designs a series of elastic flanges on the outer edge of the cover 22. These flanges can produce elastic deformation during assembly, so that the cover 22 is tightly embedded and interference fits with the milk bowl 21. The size of the end of the cover 22 away from the milk bowl 21 is larger than the size of the opening of the milk bowl 21, so that after the cover 22 and the milk bowl 21 are interference fit, the cover 22 is sealed on the opening of the milk bowl 21, further improving the sealing effect of the milk storage space 23. In order to further improve the stability of the connection, a locking structure can also be set between the milk bowl 21 and the cover 22, such as a threaded hole and a threaded connector, or a slot and a convex structure. When the cover 22 is embedded in the milk bowl 21, the cover 22 and the milk bowl 21 are locked and connected for a second time through the locking structure to ensure the reliability of the connection.

[0097] Combination Figure 3 As shown, in one embodiment of the present invention, the breast pump 1 further comprises a one-way valve 40 , the one-way valve 40 comprises a milk inlet end 41 and a milk outlet end 42 , the milk inlet end 41 is connected to the milk inlet port 221 , and at least the milk outlet end 42 is arranged in the milk storage space 23 .

[0098] In this embodiment, the one-way valve 40 has a one-way flow guiding function, and the flow guiding direction is from the milk inlet end 41 to the milk outlet end 42. Under the condition that the milk can flow from the milk inlet 221 to the milk storage space 23, the milk can be prevented from flowing out from the milk inlet 221 to the outside of the milk storage space 23 to avoid milk reflux. The one-way valve 40 can be arranged in the milk storage space 23 as a whole, and the milk inlet end 41 and the milk inlet 221 are arranged opposite to each other; or only the milk outlet end 42 of the one-way valve 40 passes through the milk inlet 221 and is arranged in the milk storage space 23, and the rest of the one-way valve 40 is arranged outside the milk storage space 23. It can be understood that as long as the position design of the one-way valve 40 can achieve one-way flow guiding to the milk storage container 20, it belongs to the protection scope of this application.

[0099] The one-way valve 40 is detachably connected to the cover body 22 or is an integrally formed structure. When the one-way valve 40 is detachably connected to the cover body 22, in order to further improve the sealing effect between the one-way valve 40 and the cover body 22, a sealing ring is sleeved on the outer periphery of the one-way valve 40, and the sealing ring, the cover body 22 and the one-way valve 40 are interference-fitted to ensure that the milk storage container 20 has a good sealing effect during the milk sucking process.

[0100] Combination Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the breast shield 10, the cover 22 and the milk bowl 21 are detachably connected in sequence along a first direction, and the milk passes through the breast shield 10 and the cover 22 along the first direction and finally flows into the milk storage space 23.

[0101] In this embodiment, the first direction is Figure 3 The breast pump 1 is connected to the cover 22 in the same direction, and the ...

[0102] Combination Figures 1 to 3 As shown, in one embodiment of the present invention, the negative pressure component 30 includes a main body housing 31 and a negative pressure pump 32, and the negative pressure pump 32 is arranged in the main body housing 31; the negative pressure component 30 is detachably mounted on the milk storage container 20, and the negative pressure pump 32 is connected to the milk storage space 23; the negative pressure pump 32 transmits the negative pressure to the breast shield 10 or the milk storage container 20 through a diaphragm or an air bag; or, the negative pressure pump 32 is connected to the milk storage space 23 through an air pipe 33, and transmits the negative pressure to the breast shield 10 or the milk storage container 20 through a diaphragm or an air bag.

[0103] In this embodiment, the negative pressure assembly 30 further includes a circuit control board and a display panel. The circuit control board is disposed in the main housing 31 and is in communication connection with the negative pressure pump 32. The display panel is disposed on the outer surface of the main housing 31 and is used to control and adjust the negative pressure pump 32. The negative pressure assembly 30 can be detachably mounted on the milk storage container 20, for example Figure 2 As shown, the negative pressure assembly 30 is installed on the milk bowl 21, and the connection method can be threaded connection or clamping, etc. The negative pressure assembly 30 can also be designed to be a separate structure from the milk storage container 20, and the negative pressure pump 32 and the milk storage container 20 are connected to the milk storage space 23 through the air pipe 33. This design makes it easy to place the negative pressure assembly 30 on a desktop to reduce the wearing weight.

[0104] Furthermore, there are three ways to connect the negative pressure pump 32 to the milk storage container 20 or the breast shield 10:

[0105] 1. Directly plug the negative pressure pump 32 into the breast shield 10 or the milk storage container 20;

[0106] 2. A diaphragm barrier 52, such as a diaphragm or an air bag, is provided at the negative pressure port of the negative pressure pump 32. Figure 2 and Figure 3 As shown, a diaphragm bracket 51 is arranged outside the end of the cover 22 embedded in the milk bowl 21, and a diaphragm barrier 52 is installed on the diaphragm bracket 51. The diaphragm barrier 52 is an air bag, which separates the negative pressure pump 32 and the milk storage space 23 to prevent the milk in the milk storage space 23 from being sucked into the negative pressure pump 32 or the pipeline. Since the air bag is an elastic structure, the negative pressure generated by the negative pressure pump 32 will cause the air bag to deform, thereby forming a negative pressure environment in the milk storage space 23.

[0107] Further, such as Figure 2As shown, a first air guide hole 212 is provided on the milk bowl 21, and a second air guide hole 224 penetrating the diaphragm support 51 and the cover 22 is provided at the end of the cover 22 embedded in the milk storage space 23. The air bag is embedded in the diaphragm support 51 and fits with the inner wall of the diaphragm support 51, so that the air bag blocks the second air guide hole 224. At the same time, a pressing part 211 is protruded on the inner wall of the milk bowl 21 toward the diaphragm support 51 of the cover 22, and the pressing part 211 presses against the inner wall of the air bag. Therefore, under the upper and lower clamping of the pressing part 211 and the diaphragm support 51, the air bag seals the second air guide hole 224 of the cover 22. The negative pressure pump 32 is connected to the first air guide hole 212 through a pipeline. When the negative pressure pump 32 is working, the suction force generated passes through the first air guide hole 212, sucks the air bag to deform toward the first air guide hole 212, and then the air bag sucks the gas in the milk storage space 23 through the second air guide hole 224 and the second nipple channel 222, so that the milk storage space 23 is in a negative pressure state, and the milk is sucked from the breast shield 10 into the milk storage space 23. Of course, the diaphragm barrier 52 can also be made of an air-permeable and liquid-impermeable material, and it is arranged between the negative pressure pump 32 and the milk storage container 20, which not only ensures that a negative pressure is formed in the milk storage space 23, but also blocks the milk from flowing back into the negative pressure pump 32.

[0108] 3. The air pipe 33 is connected to the negative pressure port of the negative pressure pump 32 , and a diaphragm barrier 52 is provided at the other end of the air pipe 33 . Similarly, negative pressure is applied to the diaphragm barrier 52 to apply negative pressure to the milk storage container 20 or the breast shield 10 .

[0109] In order to further improve the intelligence of the breast pump 1, an intelligent control system is added to the design of the main housing 31. The system can monitor the output of negative pressure in real time and display it on the display screen outside the main housing 31. The user can adjust the negative pressure as needed to achieve a personalized milk pumping experience.

[0110] The present application proposes an inventive concept of a wearable breast pump 1, which solves the problem that the existing milk bowl 21 and the breast shield 10 are together enclosed to form a milk storage space 23, which is inconvenient for users to use. The breast pump 1 is not limited to the structural design described in the above embodiment. Regarding the specific structure of the negative pressure component 30 and the diaphragm barrier 52, and the installation method of the various parts of the breast pump 1, the present application also provides the following 6 different embodiments to further illustrate the inventive concept of the present application.

[0111] First embodiment:

[0112] like Figure 4 and Figure 5As shown, the negative pressure assembly 30 is installed above the milk bowl 21, and is combined with the milk bowl 21 to form a hemispherical structure, so as to be worn in a bra. A diaphragm bracket 51 and an air inlet cylinder 53 are arranged between the milk bowl 21 and the negative pressure assembly 30, wherein the air inlet cylinder 53 is embedded in the first air guide hole 212 of the milk bowl 21, and an air pipe 33 is arranged on the diaphragm bracket 51. The negative pressure pump 32 in the negative pressure assembly 30 is connected to the air inlet cylinder 53 through the air pipe 33 arranged on the diaphragm bracket 51. The diaphragm barrier 52 is arranged between the milk bowl 21 and the air inlet cylinder 53, and is enclosed with the air inlet cylinder 53 to form a negative pressure chamber. When milk is needed to be sucked, the negative pressure generated by the negative pressure pump 32 passes through the diaphragm barrier 52, the air tube 33, and the air inlet cylinder 53, and sucks the negative pressure cavity formed by the diaphragm barrier 52 and the air inlet cylinder 53. The diaphragm barrier 52 is a deformable material, such as an elastic air bag, which deforms under the action of negative pressure, thereby causing negative pressure to form in the milk storage space 23 formed by the cover 22 and the milk bowl 21. When milk is sucked, the milk passes through the breast shield 10 and the cover 22 in the horizontal direction, and then passes through the one-way valve 40 in the vertical direction to flow into the milk storage space 23.

[0113] Second embodiment:

[0114] like Figure 6 As shown, the negative pressure assembly 30 includes a main housing 31, a negative pressure pump 32 and an air pipe 33. The negative pressure pump 32 is arranged in the main housing 31 and communicated with one end of the air pipe 33. A pipe joint connected to the milk storage space 23 is arranged on the outside of the milk bowl 21, and the other end of the air pipe 33 is used for a detachable connecting pipe joint to achieve the communication between the negative pressure pump 32 and the milk storage space 23. A breathable membrane is arranged inside the pipe joint, which can pass gas and block liquid, so that the negative pressure pump 32 provides negative pressure for the milk storage space 23 while preventing the milk in the milk storage space 23 from flowing back into the air pipe 33. Of course, a diaphragm barrier 52 can also be arranged inside the milk bowl 21. The diaphragm barrier 52 blocks the pipe joint from the milk storage space 23. The diaphragm barrier 52 is sucked by the negative pressure pump 32 to deform it, thereby forming a negative pressure in the milk storage space 23.

[0115] The milk bowl 21 is hemispherical in shape so as to be worn in a bra. The cover 22 is connected to the milk bowl 21 and encloses a milk storage space 23. The breast shield 10 is detachably embedded in the side of the cover 22 away from the milk bowl 21. When sucking milk, the milk passes through the breast shield 10 and the cover 22 in the horizontal direction, and then flows into the milk storage space 23 through the one-way valve 40 in the vertical direction.

[0116] Third embodiment:

[0117] like Figure 7 and Figure 8As shown, the negative pressure assembly 30 and the milk bowl 21 are combined to form a hemispherical structure, so that it is easy to wear in a bra. A pipe is provided on the side of the milk bowl 21 facing the negative pressure assembly 30, and a first air guide hole 212 is opened on the pipe. The diaphragm barrier 52 is an elastic air bag, and is arranged between the first air guide hole 212 and the milk storage space 23. The elastic air bag is sucked by the negative pressure pump 32 to cause it to deform, thereby forming a negative pressure in the milk storage space 23. The cover body 22 is covered on the milk bowl 21, and the breast shield 10 is detachably connected to the side of the cover body 22 away from the milk bowl 21. When sucking milk, the milk passes through the breast shield 10 and the cover body 22 in the horizontal direction, and then flows into the milk storage space 23 through the one-way valve 40 in the vertical direction.

[0118] Fourth embodiment:

[0119] like Fig. 9 and Fig.10 As shown, the milk bowl 21 is a hemispherical structure, so that it can be worn in a bra. The negative pressure component 30 includes a main housing 31, a negative pressure pump 32 and an air pipe 33. The negative pressure pump 32 is arranged inside the main housing 31 and communicated with the air pipe 33. The other end of the air pipe 33 is connected to the first air guide hole 212 opened on the surface of the milk bowl 21. A diaphragm bracket 51 is arranged on one side of the cover body 22. The surface of the cover body 22 is also provided with a second air guide hole 224 connected to the milk storage space 23. A diaphragm barrier 52 is arranged inside the milk bowl 21. The diaphragm barrier can be an elastic air bag, which is embedded in the diaphragm bracket 51 and is located between the first air guide hole 212 and the second air guide hole 224. The negative pressure pump 32 sucks the elastic air bag through the first air guide hole 212 to cause it to deform, thereby forming a negative pressure in the milk storage space 23. When expressing milk, the milk passes through the breast shield 10 and the cover 22 in the horizontal direction, and then passes through the one-way valve 40 in the vertical direction to flow into the milk storage space 23.

[0120] Fifth embodiment:

[0121] like Fig.11 and Fig.12 As shown, on the basis of the fourth embodiment, two air pipes 33 are provided, and the two air pipes 33 are both connected to the same negative pressure pump 32. Two milk storage containers 20 and two breast shields 10 are provided, and the two milk storage containers 20 are respectively connected to the two air pipes 33. Therefore, the two milk storage containers 20 and the breast shields 10 can be controlled by the negative pressure component 30 to suck milk from two breasts respectively. Further, the negative pressure component 30 also includes an air circuit switching structure, which is provided between the two air pipes 33 and the negative pressure pump 32. The two air pipes 33 are connected to the negative pressure pump 32 through the air circuit switching structure. Different air pipes 33 can be switched to be connected to the negative pressure pump 32 through the air circuit switching structure, thereby achieving the effect of sucking milk from a single breast or two breasts.

[0122] Sixth embodiment:

[0123] like Fig.13 and Fig.14 As shown, the milk bowl 21 and the negative pressure assembly 30 are combined to form a hemispherical structure, so as to be worn in a bra. Different from the above embodiment, in this embodiment, the milk bowl 21 is located above the negative pressure assembly 30. A diaphragm barrier 52 is provided between the negative pressure pump 32 and the first air guide hole 212 of the milk bowl 21. The diaphragm barrier 52 is an elastic air bag. The elastic air bag is sucked by the negative pressure pump 32 to deform it, thereby forming a negative pressure in the milk storage space 23. In this embodiment, when sucking milk, the milk passes through the breast shield 10 and the cover 22 in the horizontal direction in sequence, and finally flows into the milk storage space 23.

[0124] It can be understood that the above embodiments are all partial embodiments listed based on the inventive concept of enclosing the cover body 22 and the milk bowl 21 to form the milk storage space 23 according to the different positions, shapes and matching relationships of the various components of the breast pump 1. The breast pump 1 proposed in this application is not limited to the structural features described in the above embodiments. As long as the technical solutions adopt the inventive concept of this application, they belong to the protection scope of this application.

[0125] The present invention further provides a milk storage assembly 200, which includes an assembly and a milk storage container 20. The specific structure of the milk storage container 20 refers to the above embodiment. Since the milk storage assembly 200 adopts all the technical solutions of all the embodiments of the milk storage container 20, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Fig.15 and Fig.16 As shown, in one embodiment of the present invention, a milk storage container 20 is formed with a milk storage space 23 having a milk inlet 221 at one end, and the assembly part is detachably connected to the milk storage container 20 and seals the milk inlet 221 .

[0126] In this embodiment, the assembly can be a nipple 201 or a sealing plug 202, which is detachably connected to the milk storage container 20 and seals the milk inlet 221. This design allows the milk storage assembly 200 to be used for both feeding and storing milk, providing more usage scenarios.

[0127] Therefore, the milk storage container 20 in the present application can be used as a component of the breast pump 1, and cooperate with the breast shield 10 and the negative pressure component 30 to pump milk, and can also be used as a component of the milk storage component 200, and cooperate with the assembly parts to store milk or a container for feeding, thereby improving the utilization rate of the milk storage container 20.

[0128] Combination Fig.15As shown, in one embodiment of the present invention, the assembly part is a nipple 201, and the nipple 201 is covered on the milk inlet 221. After sucking milk, the milk storage assembly 200 can be used for direct feeding, which improves the convenience of feeding. The nipple 201 is connected to the side of the milk storage container 20 with the milk inlet 221. Specifically, the nipple 201 has a certain elasticity, and the nipple 201 can be sleeved on the milk storage container 20; one end of the nipple 201 can also be inserted into the milk inlet 221 of the milk storage container 20 and have an interference fit with the milk storage container 20; or the nipple 201 and the milk storage container 20 can be detachably connected through a connector, and the connector can be an elastic clip, a buckle, or other structures.

[0129] Combination Fig.16 As shown, in one embodiment of the present invention, the assembly includes a sealing plug 202, the sealing plug 202 is inserted into the milk inlet 221, and the milk storage assembly 200 is used to store milk.

[0130] In this embodiment, after the breast pump 1 has finished sucking milk, the breast shield 10 is separated from the cover 22, and then the sealing plug 202 is inserted into the milk inlet 221 to seal the milk storage space 23, so that the milk storage assembly 200 can be used to store milk. The sealing plug 202 ensures that the milk can be stored in a sealed manner to prevent leakage and contamination of the milk.

[0131] At least the portion of the sealing plug 202 inserted into the milk inlet 221 is made of elastic material, and the size of the insertion end is slightly larger than the inner diameter of the milk inlet 221, so that after the sealing plug 202 is inserted into the milk inlet 221, the sealing plug 202 and the edge of the milk inlet 221 of the milk storage container 20 are tightly matched to form a first seal. A secondary sealing ring is also convexly provided on the outer periphery of the sealing plug 202. When the insertion end is inserted into the milk inlet 221, the secondary sealing ring is tightly abutted against the outer surface of the cover body 22 to form a second seal. This two-stage sealing structure ensures the sealing of milk in the milk storage space 23.

[0132] In order to facilitate the use of the user, the assembly also includes a handle structure that is easy to grasp and is arranged at one end of the sealing plug 202 away from the milk storage container 20. This allows the user to obtain a better grip and easier operation when inserting or removing the sealing plug 202.

[0133] Combination Fig.15 and Fig.16 As shown, in one embodiment of the present invention, the milk storage container 20 includes a milk bowl 21 and a cover 22. The cover 22 is covered on the milk bowl 21 and encloses the milk bowl 21 to form a milk storage space 23. A milk inlet 221 is opened on the surface of the cover 22. The assembly part is detachably connected to the milk inlet 221 of the cover 22. The milk inlet 221 of the cover 22 is also used for detachably connecting the breast shield 10.

[0134] In this embodiment, since the milk storage container 20 is used to connect the breast shield 10 to achieve the function of sucking milk, and is also used to connect the assembly to achieve the function of storing milk. Therefore, the present application designs the connection structure or connection method of the milk storage container 20 and the assembly to be the same as the connection structure or connection method of the breast shield 10. For example, when the breast shield 10 inserts the end into the milk inlet of the cover body 22 to achieve an interference fit between the two, the assembly is also designed to be compatible with the milk inlet of the cover body 22, and is inserted into the milk inlet to achieve an interference fit between the two. When the breast shield 10 is connected to the outer periphery of the cover body 22 by a hook, the assembly is also designed with a hook, and it is connected to the outer periphery of the cover body 22 by hooking. The above structural design can improve the applicability and compatibility of the milk storage container 20, and facilitate the user's quick disassembly and assembly.

[0135] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
