[0048] Typically, a breast pump assembly includes a flange for fitting the breast and a nipple channel for accommodating the nipple. During use, the nipple channel comes into contact with milk and needs to be cleaned after each use. The nipple channel is an inner cavity and is not easy to clean. The closed bottom of the nipple channel is even more difficult to clean. Over time, it is easy to harbor dirt and grime, which is unhygienic and detrimental to the health of mother and baby.

[0049] In view of this, the present invention provides a novel milk suction assembly and a breast pump to solve the defects in the prior art.

[0050] As shown in Figures 1 and 2, the breast pump assembly 10 provided by the embodiment of the present invention includes a breast shield 11 and a nipple channel end cap 12. The breast shield 11 includes a nipple channel 111 and a flange 112. The nipple channel 111 is a tubular component with two ends open. The flange 112 is connected to one end of the nipple channel 111. The nipple channel end cap 12 is detachably connected to the other end of the nipple channel 111 and is used to seal the nipple channel 111. Specifically, the flange 112 and the nipple channel 111 both have a hollow cavity. The flange 112 has a trumpet-shaped structure and is used to be attached to the breast. The nipple channel 111 has a tubular structure. When the flange 112 is placed on the breast, the nipple extends into the cavity of the nipple channel 111.

[0051] With the above technical solution, by configuring the nipple passage 111 as a tubular component with both ends open, cleaning only requires cleaning the tube wall, eliminating the problem of difficulty in cleaning due to the seal at the bottom of the tube. By detachably connecting the nipple passage end cap 12 to the other end of the nipple passage 111, when the nipple passage 111 needs to be cleaned after milking, the nipple passage end cap 12 can be removed from the nipple passage 111, facilitating cleaning. During milking, the nipple passage end cap 12 can be installed at the end of the nipple passage 111 to seal or cover the nipple passage 111. Therefore, the breast pump assembly 10 provided in this embodiment can conveniently and quickly clean the nipple passage 111, and greatly improves the cleaning efficiency.

[0052] 3 to 6 , the milking assembly 10 further includes a negative pressure chamber-forming member 13, a negative pressure chamber cover 14, and a suction diaphragm 15. The negative pressure chamber-forming member 13 is positioned outside the nipple passage 111 and includes a negative pressure chamber 131 communicating with the nipple passage 111. The negative pressure chamber cover 14 covers and seals the negative pressure chamber 131. The suction diaphragm 15 is positioned between the negative pressure chamber-forming member 13 and the negative pressure chamber cover 14. During installation, the suction diaphragm 15 is placed within the negative pressure chamber 131 and forms a sealed space with the negative pressure chamber-forming member 13. The suction diaphragm 15 is deformable, causing changes in the air pressure within the nipple passage 111, thereby promoting lactation.

[0053] As one embodiment, referring to Figures 4 and 6 , the nipple channel end cap 12 can be connected to the suction diaphragm 15 and the negative pressure hatch 14, and includes a cover body 121 and a sealing portion 122. The cover body 121 is connected to the negative pressure hatch 14, and the sealing portion 122 is connected to the negative pressure hatch 14. Preferably, the cover body 121 and the negative pressure hatch 14 are integrally formed, and the sealing portion 122 is integrally formed with the negative pressure hatch 14. During installation, the sealing portion 122 connected to the suction diaphragm 15 is connected between the cover body 121 and the end of the nipple channel 111. When the negative pressure hatch 14 and the suction diaphragm 15 are removed, the nipple channel end cap 12 can be removed together. In this embodiment, the negative pressure chamber 131 communicates with the nipple channel 111 through the opening of the nipple channel 111 near the nipple channel end cap 12. Specifically, the sealed space formed by the suction diaphragm 15 and the negative pressure chamber forming member 13 communicates with the nipple channel 111 through the opening of the nipple channel 111 near the nipple channel end cap 12, thereby sealing the nipple channel 111. In this way, the pressure change generated by the deformation of the suction diaphragm 15 is transmitted from the opening of the nipple channel 111 near the nipple channel end cap 12 to the nipple channel 111. In the above embodiment, when subjected to negative pressure, the suction diaphragm 15 deforms, causing the negative pressure chamber 131 to communicate with the opening of the nipple channel 111 near the nipple channel end cap 12. In other embodiments, as shown in FIG14 , the suction diaphragm can be formed on the nipple channel end cap 12. Specifically, the nipple channel end cap 12 not only covers the opening of the nipple channel 111 near the nipple channel end cap 12, but also serves as a suction diaphragm for transmitting negative pressure during deformation. In another embodiment, as shown in FIG5 , an air hole 19 is further provided between the negative pressure chamber 131 and the nipple channel 111. The sealed space formed by the suction diaphragm 15 and the negative pressure chamber forming member 13 is connected to the nipple channel 111 through the opening of the nipple channel 111 near the nipple channel end cap 12 and the air hole 19.

[0054] 4 and 7 , a negative pressure interface 16 for introducing negative pressure into the suction diaphragm 15 is provided on the cover 121 .

[0055] In one embodiment, the nipple channel end cap 12 is connected to the negative pressure hatch 14. The nipple channel end cap 12 includes a cover 121 and a sealing portion 122. The cover 121 is connected to the negative pressure hatch 14 and is preferably integrally formed with the negative pressure hatch 14. The sealing portion 122 is provided between the cover 121 and the end of the nipple channel 111 to achieve a seal. When the negative pressure hatch 14 is removed, the nipple channel end cap 12 can be removed together. The sealing portion 122 is used to prevent the leakage of gas and liquid in the nipple channel 111, improving the airtightness and liquid sealing of the nipple channel 111. The sealing portion 122 can be a sealing rubber ring or a sealing rubber gasket.

[0056] An air hole 19 is provided between the negative pressure chamber 131 and the nipple passage 111. The negative pressure chamber 131 and the nipple passage 111 are connected via the air hole 19. The negative pressure chamber cover 14 is provided with a negative pressure port 16 for supplying negative pressure to the suction diaphragm 15. Specifically, the sealed space formed by the suction diaphragm 15 and the negative pressure chamber forming member 13 is connected to the nipple passage 111 via the air hole 19. The air hole 19 is used to transmit pressure changes generated by the deformation of the suction diaphragm 15 to the nipple passage 111.

[0057] In one embodiment, the nipple channel end cap 12 is connected to the suction diaphragm 15. The nipple channel end cap 12 includes a cover 121 and a sealing portion 122. The sealing portion 122 is connected to the suction diaphragm 15 and is preferably integrally formed with the suction diaphragm 15. When the suction diaphragm 15 is removed, the nipple channel end cap 12 can be removed together. Part of the inner shell of the main unit can serve as the cover 121 and be located at the end of the sealing portion 122 away from the nipple channel 111. Alternatively, a dedicated cover 121 can be provided and located at the end of the sealing portion 122 away from the nipple channel 111. With this embodiment, the negative pressure chamber 131 is connected to the nipple channel 111 through the opening of the nipple channel 111 close to the nipple channel end cover 12. Specifically, the sealed space formed by the suction diaphragm 15 and the negative pressure chamber forming member 13 is connected to the nipple channel 111 through the opening of the nipple channel 111 close to the nipple channel end cover 12, and seals the nipple channel 111. In this way, the pressure change caused by the deformation of the suction diaphragm 15 is transmitted from the opening of the nipple channel 111 close to the nipple channel end cover 12 to the nipple channel 111.

[0058] The negative pressure hatch cover 14 is provided with a negative pressure interface 16 for introducing negative pressure into the suction diaphragm 15 .

[0059] 8 and 9 , the nipple channel end cap 12 is connected to the suction diaphragm 15 and is preferably integrally formed with the suction diaphragm 15. When the suction diaphragm 15 is removed, the nipple channel end cap 12 can be removed together.

[0060] As shown in FIG9 , the nipple passage end cap 12 includes a covering portion 123 and a clamping portion 124. The covering portion 123 is connected to the suction diaphragm 15, and the clamping portion 124 is connected to one side of the covering portion 123. When the covering portion 123 covers the open end of the nipple passage 111, the clamping portion 124 clamps into the opening of the nipple passage 111. Because the clamping portion 124 is elastic, it can tightly fit with the inner wall of the nipple passage 111, achieving a connection and sealing effect. In this way, the nipple passage end cap 12 covers and seals the open end of the nipple passage 111.

[0061] An air hole 19 is provided between the negative pressure chamber 131 and the nipple passage 111, communicating with the negative pressure chamber 131 and the nipple passage 111 through the air hole 19. The negative pressure chamber cover 14 is provided with a negative pressure port 16 for introducing negative pressure into the suction diaphragm 15. Specifically, the sealed space formed by the suction diaphragm 15 and the negative pressure chamber forming member 13 communicates with the nipple passage 111 through the air hole 19. The air hole 19 is used to transmit pressure changes generated by the deformation of the suction diaphragm 15 to the nipple passage 111.

[0062] The above embodiments can simplify parts, facilitate assembly and disassembly of the machine, and simplify cleaning.

[0063] In one embodiment, the nipple channel end cap 12 is independently provided and includes a cover body 121 and a sealing portion 122. The sealing portion 122 is provided between the cover body 121 and the end of the nipple channel 111 to achieve a seal. The sealing portion 122 is used to prevent gas and liquid in the nipple channel 111 from leaking out, thereby improving the air tightness and liquid sealing of the nipple channel 111. The sealing portion 122 can be a sealing rubber ring or a sealing rubber gasket.

[0064] An air hole 19 is provided between the negative pressure chamber 131 and the nipple passage 111, communicating with the negative pressure chamber 131 and the nipple passage 111 through the air hole 19. The negative pressure chamber cover 14 is provided with a negative pressure port 16 for introducing negative pressure into the suction diaphragm 15. Specifically, the sealed space formed by the suction diaphragm 15 and the negative pressure chamber forming member 13 communicates with the nipple passage 111 through the air hole 19. The air hole 19 is used to transmit pressure changes generated by the deformation of the suction diaphragm 15 to the nipple passage 111.

[0065] In order to transmit the pressure changes caused by the deformation of the suction diaphragm 15 to the nipple channel 111, in one embodiment, the nipple channel end cover 12 is integrally formed with the negative pressure cabin cover 14 and the suction diaphragm 15, and the pressure changes caused by the deformation of the suction diaphragm 15 are transmitted to the nipple channel 111 from the end opening of the nipple channel 111.

[0066] In order to transmit the pressure changes caused by the deformation of the suction diaphragm 15 to the nipple channel 111, in one embodiment, an air hole 19 is provided between the negative pressure chamber forming member 13 and the nipple channel 111, which is used to transmit the pressure changes caused by the deformation of the suction diaphragm 15 to the nipple channel 111. Preferably, the negative pressure interface 16 is provided on the side of the negative pressure chamber cover 14 opposite to the suction diaphragm 15.

[0067] As shown in Figures 1 and 12 , the milking assembly 10 further includes an air duct 17. This air duct 17 is located on the side of the nipple channel end cap 12, away from the nipple channel 111. This air duct 17 is configured to extend into the main unit 20 and communicate with the suction pump. The air duct 17 is positioned axially along the end of the nipple channel 111. This allows for quick and accurate insertion into the main unit 20 during assembly of the milking assembly 10 and main unit 20, significantly accelerating assembly. In another embodiment, as shown in Figures 8 and 9 , the air duct 17 is located on the side of the negative pressure hatch 14, away from the suction diaphragm 15.

[0068] The suction diaphragm 15 is connected to the negative pressure cabin cover 14 and is detachably connected to the negative pressure cabin forming member 13. In this way, the suction diaphragm 15 and the negative pressure cabin cover 14 can be removed from the negative pressure cabin forming member 13, making it easy to clean the suction diaphragm 15, the negative pressure cabin forming member 13 and other components.

[0069] The suction diaphragm 15 and the negative pressure hatch 14 are integrally formed. This reduces the number of components in the breast pump assembly 10 and prevents component loss due to an excessive number of components. It is understood that in other embodiments, the suction diaphragm 15 and the negative pressure hatch 14 may be detachably connected.

[0070] The breast shield 11 and the negative pressure chamber forming member 13 are integrally formed. Reducing the number of parts in the breast pump assembly 10 helps speed up assembly of the breast pump assembly 10 and also prevents the loss of parts due to the excessive number of parts in the breast pump assembly 10. Of course, in specific applications, as an alternative embodiment, the breast shield 11 and the negative pressure chamber forming member 13 can also be detachably connected.

[0071] 4 , the nipple channel 111 is further provided with a milk outlet 1111 , which is used for allowing milk to flow out of the nipple channel 111 . Specifically, the milk outlet 1111 is provided between the openings at both ends of the nipple channel 111 .

[0072] 4 , 6 , and 11 , the milk pump assembly 10 further includes a connector 18 , which is connected to the outside of the nipple channel 111 and circumferentially disposed around the milk outlet 1111. The connector 18 is used to connect to and cover the milk bottle 30 of the breast pump 100. In this manner, the milk pump assembly 10 and the milk bottle 30 are connected.

[0073] When the milking assembly 10 is placed on the breast, the milk outlet 1111 is located at the lowest point of the nipple passage 111. Specifically, after milk is expressed from the breast, it flows under the action of gravity. By arranging the milk outlet 1111 at the lowest point of the nipple passage 111, the milk can flow to the milk outlet 1111 as much as possible, and then flow into the feeding bottle 30, thereby preventing milk from accumulating in the nipple passage 111.

[0074] The breast shield 11 and nipple passage 111 are integrally formed. Reducing the number of parts in the breast pump assembly 10 helps speed up assembly and prevents the loss of parts due to the excessive number of parts in the breast pump assembly 10. Of course, in specific applications, as an alternative embodiment, the nipple passage 111 and the connector 18 can also be detachably connected.

[0075] 10 , the present invention also provides a breast pump 100 including the aforementioned milk pump assembly 10. By using the aforementioned milk pump assembly 10, the nipple channel 111 can be cleaned conveniently and quickly, and the degree of cleanliness of the cleaning can be greatly improved.

[0076] 1, 11, and 12, the breast pump assembly 10 further includes an air tube 17, which is disposed on a side of the nipple channel end cap 12 away from the nipple channel 111. The breast pump 100 further includes a main unit 20, which has a socket 21 that engages with the air tube 17. The engagement of the socket 21 with the air tube 17 allows for quick and accurate assembly of the breast pump assembly and main unit 20.

[0077] The airway tube 17 is coaxially arranged with the nipple passage 111. This allows the airway tube 17 to be quickly and accurately aligned with the receptacle 21 of the main unit 20 during assembly of the breast pump assembly 10, improving assembly efficiency. It will be appreciated that in other embodiments, the axial direction of the airway tube 17 may be close to the axial direction of the nipple passage 111. For example, the angle between the axial direction of the airway tube 17 and the axial direction of the nipple passage 111 may be within a range of ±20°.

[0078] The air guide tube 17 is integrally formed with the nipple passage end cap 12. This prevents air leakage between the air guide tube 17 and the nipple passage end cap 12 due to assembly error. Of course, in specific applications, as an alternative embodiment, the air guide tube 17 and the nipple passage end cap 12 can also be made separately.

[0079] 4 , 6 , and 11 , the nipple channel 111 is further provided with a milk outlet 1111. The milk pump assembly 10 further includes a connector 18 circumferentially disposed around the milk outlet 1111. The breast pump 100 further includes a feeding bottle 30. The connector 18 is connected to the feeding bottle 30 and covers the mouth of the feeding bottle 30, so that the milk outlet 1111 communicates with the mouth of the feeding bottle 30. In this manner, the milk pump assembly 10 is connected to the feeding bottle 30, and milk in the breast receiving cavity flows into the feeding bottle 30.

[0080] As shown in FIG13 , the bottom of a feeding bottle 30 is provided with a depression 31. Specifically, the concave surface of the bottom of the feeding bottle 30 is configured to allow the feeding bottle 30 to make line contact with the support surface. When the support surface is at a low temperature, this slows down the temperature drop of the milk compared to a surface contact method.

[0081] 6 and 11 , the breast pump 100 further includes a sealing member 40, which is disposed between the connector 18 and the feeding bottle 30 and is used to seal the mouth of the feeding bottle 30. This improves the sealing performance of the feeding bottle 30 during the milk-extraction process, and when the breast pump 100 is used to extract milk, the user can bend over or lie flat to effectively prevent milk from leaking out of the feeding bottle 30.

[0082] The breast pump 100 is an integrated wearable breast pump that can be worn independently inside a bra to express milk.

[0083] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
