[0042] like Figures 1 to 5 As shown, the milk suction assembly provided by the embodiment of the utility model is applied to a breast pump, and includes a fixing part, a diaphragm support 10 and an outer milk guide 20; the diaphragm support 10 and the outer milk guide 20 are both connected to the fixing part, and when the breast pump is placed on the breast, the outer milk guide 20 is located above the diaphragm support 10; that is, when the user wears the breast pump to suck milk, the outer milk guide 20 is located above the diaphragm support 10. Among them, the diaphragm support 10 has a negative pressure cavity 11, and the outer milk guide 20 is provided with a first milk guide channel 21, a milk flow hole 22 connecting the first milk guide channel 21 and the milk storage cavity 81 of the breast pump, and a first air guide hole 23 connecting the first milk guide channel 21 and the negative pressure cavity 11. By arranging the outer milk guide 20 above the diaphragm support 10, it is possible to avoid the diaphragm support 10 blocking the outer milk guide 20, so that it is convenient for the user to check the situation in the first milk guide channel 21.

[0043] When in use, negative pressure suction enters the first milk guide channel 21 through the first air guide hole 23, and the milk is sucked out and flows into the first milk guide channel 21, and then flows into the milk storage cavity 81 through the milk flow hole 22 for temporary storage.

[0044] See also Figure 2 and Figure 3The milk suction assembly also includes an inner milk guide piece 30, at least part of which extends into the first milk guide channel 21, and the inner milk guide piece 30 is provided with a second milk guide channel 311 and a second air guide hole 33 connected to the second milk guide channel 311, and the second milk guide channel 311 is connected to the first milk guide channel 21; wherein, the inner milk guide piece 30 and the inner side wall of the outer milk guide piece 20 are enclosed to form an air guide channel 40, the first air guide hole 23 and the second air guide hole 33 are both connected to the air guide channel 40, and the second air guide hole 33 is located above the central axis M of the second milk guide channel 311 when the breast pump is placed on the breast. When at least part of the inner milk guide piece 30 is extended into the first milk guide channel 21, the inner milk guide piece 30 is located above the diaphragm support 10, that is, the second milk guide channel 311 is located above the diaphragm support 10, so that the diaphragm support 10 can be prevented from blocking the inner milk guide piece 30, and the user can check the situation in the second milk guide channel 311. When the breast pump is placed on the breast, the second air guide hole 33 is located above the first air guide hole 23, that is, when the user wears the breast pump to suck milk, the second air guide hole 33 is located above the first air guide hole 23. Optionally, the first air guide hole 23 is located below the central axis M of the second milk guide channel 311. The extension direction of the central axis M is the same as the extension direction of the second milk guide channel 311. When the breast pump is placed on the breast, the extension direction of the second milk guide channel 311 is horizontal or substantially horizontal, and the central axis M is also horizontal or substantially horizontal.

[0045] When in use, the nipple is aligned with or extended into the second milk guide channel 311, and the negative pressure suction enters the air guide channel 40 through the first air guide hole 23, and then enters the second milk guide channel 311 through the second air guide hole 33. After the milk is sucked out, it flows into the second milk guide channel 311, and then flows into the first milk guide channel 21 and flows into the milk storage chamber 81 through the milk flow hole 22 for temporary storage.

[0046] By adopting the above technical solution, by forming an air guide channel 40, and arranging the first air guide hole 23 and the second air guide hole 33 to connect to the air guide channel 40, the negative pressure chamber 11 is connected to the second milk guide channel 311, and negative pressure can be generated in the second milk guide channel 311, thereby realizing the sucking out of milk; by arranging the second air guide hole 33 above the central axis M of the second milk guide channel 311, the milk in the second milk guide channel 311 is not easy to flow into the air guide channel 40 and the negative pressure chamber 11 through the second air guide hole 33, thereby avoiding the contamination of the negative pressure chamber 11 and the reduction of the suction performance of the breast pump. Therefore, the milk suction assembly provided in this embodiment can prevent milk from flowing from the milk guide channel (the first milk guide channel 21 and / or the second milk guide channel 311) into the negative pressure chamber 11, thereby avoiding the contamination of the negative pressure chamber 11 and the reduction of the suction performance of the breast pump.

[0047] As an embodiment, when the breast pump is placed on the breast, the angle between the second air guide hole 33 and the central axis M of the second milk guide channel 311 and the horizontal plane is 80° to 100°. Preferably, the angle between the second air guide hole 33 and the central axis M of the second milk guide channel 311 and the horizontal plane is 90°, that is, the second air guide hole 33 is located at the top of the second milk guide channel 311, which has a better effect of preventing milk from flowing into the air guide channel 40 through the second air guide hole 33.

[0048] As an embodiment, the outer milk conducting piece 20 and the diaphragm support 10 are arranged side by side and share a common wall, that is, the outer milk conducting piece 20 and the diaphragm support 10 have a common side wall, one side of the side wall faces the first milk conducting channel 21, and the other side faces the negative pressure chamber 11, wherein the first air conducting hole 23 is formed on the side wall.

[0049] As an embodiment, the outer layer milk guide piece 20 is generally a cylindrical structure with an opening at one end, and its cavity forms a first milk guide channel 21, a milk flow hole 22 is opened on the bottom wall, and a first air guide hole 23 is opened on the side wall. When the breast pump is placed on the breast, the outer layer milk guide piece 20 is basically arranged horizontally, and its opening faces the breast. The inner layer milk guide piece 30 is generally a tubular structure, and its cavity forms a second milk guide channel 311. When the inner layer milk guide piece 30 extends into the outer layer milk guide piece 20, the second milk guide channel 311 is connected to the first milk guide channel 21 through the opening at one end thereof.

[0050] See also Figure 3 , Figure 6 and Figure 7 The inner milk-conducting member 30 includes a milk-conducting body 31 and a soft rubber ring 32; the milk-conducting body 31 extends into the first milk-conducting channel 21, and is provided with a second milk-conducting channel 311 and a first perforation 312 connected to the second milk-conducting channel 311; the soft rubber ring 32 is sleeved on the outer periphery of the milk-conducting body 31 and is located between the milk-conducting body 31 and the outer milk-conducting member 20, the soft rubber ring 32 is provided with a first annular groove 321 and a second perforation 322 connected to the first annular groove 321, the outer milk-conducting member 20 seals the first annular groove 321 to form an air-conducting channel 40, and the first perforation 312 and the second perforation 322 form a second air-conducting hole 33 correspondingly. Among them, the milk-conducting body 31 is roughly tubular in structure. The soft rubber ring 32 is sleeved on the outer periphery of the milk-conducting body 31, and is sandwiched between the milk-conducting body 31 and the outer milk-conducting member 20, and the air-conducting channel 40 formed by the enclosed has good sealing performance to ensure that the air-conducting channel 40 will not leak.

[0051] See also Figure 6 and Figure 7The outer wall of the milk guide body 31 is provided with a second annular groove 313, and the soft rubber ring 32 is embedded in the second annular groove 313. Such a configuration increases the stability of the connection between the soft rubber ring 32 and the milk guide body 31, and the soft rubber ring 32 does not protrude from the milk guide body 31 as a whole, which can reduce the gap between the milk guide body 31 and the outer milk guide piece 20, thereby improving the assembly stability of the milk guide body 31 and the outer milk guide piece 20.

[0052] As an embodiment, the second annular groove 313 is formed at one end of the milk guide body 31 extending into the first milk guide channel 21, that is, the second annular groove 313 is formed at one end of the milk guide body 31 close to the milk flow hole 22. In this way, the air guide channel 40 is formed at one end of the milk guide body 31 close to the milk flow hole 22, and the distance between the air guide channel 40 and the milk flow hole 22 is small, which is conducive to the flow of milk to the milk flow hole 22; in addition, this arrangement, compared with the second annular groove 313 being arranged in the middle of the milk guide body 31, can quickly assemble the soft rubber ring 32.

[0053] As an embodiment, the inner layer milk guide piece 30 is detachably connected to the outer layer milk guide piece 20. In this way, when using the breast pump, the inner layer milk guide piece 30 is assembled in the outer layer milk guide piece 20 to prevent milk from flowing into the negative pressure chamber 11; when the milk is sucked and the breast pump is not used, the inner layer milk guide piece 30 can be removed from the outer layer milk guide piece 20, which is conducive to the cleaning of the inner layer milk guide piece 30 and the outer layer milk guide piece 20. Of course, in other embodiments, the inner layer milk guide piece 30 is also fixedly connected to the outer layer milk guide piece 20.

[0054] See also Figure 3 The milk suction assembly further includes an elastic membrane 50, which is circumferentially connected to the membrane support 10 and extends into the negative pressure chamber 11.

[0055] See also Figure 5 and Figure 6 The milk pump assembly further includes a negative pressure chamber cover 60, which is disposed at the opening of the negative pressure chamber 11 and seals the negative pressure chamber 11. In a specific application, a negative pressure hole 61 is provided on the negative pressure chamber cover 60 to connect the negative pressure chamber 11 with the pump body of the breast pump.

[0056] As an implementation mode, the negative pressure chamber cover 60 is connected to the milk guide body 31 and is integrally formed with the milk guide body 31. This arrangement reduces the number of parts, prevents the loss of parts, and improves the assembly efficiency of the breast pump.

[0057] See also Figure 6The milk pump assembly further comprises a handle 70, which is connected to the inner milk guide 30. The handle 70 is provided to provide a fulcrum for the user, so that the user can disassemble and install the inner milk guide.

[0058] As an embodiment, the handle 70 is connected to the milk guide body 31 and is integrally formed with the milk guide body 31. This arrangement, on the one hand, reduces the number of parts, prevents the loss of parts, and improves the assembly efficiency of the breast pump; on the other hand, reduces the processing steps and speeds up the processing efficiency.

[0059] See also Figure 2 and Figure 3 The milk pump assembly further comprises a container body 80, a sealing cover 90, a main body shell 100 and a breast shield 110; the sealing cover 90 covers and seals the container body 80, and is enclosed with the container body 80 to form a milk storage cavity 81; the main body shell 100 is disposed between the sealing cover 90 and the breast shield 110, and the breast shield 110 is used to cover the breast; the fixing member is the sealing cover 90 or the main body shell 100 or the breast shield 110, and the outer layer milk guide member 20 and the diaphragm support 10 both extend from the fixing member toward the direction close to the milk storage cavity 81. In this embodiment, the fixing member is the sealing cover 90, and the outer layer milk guide member 20 and the diaphragm support 10 are both connected to the side of the sealing cover 90 facing the milk storage cavity 81, and extend toward the direction close to the milk storage cavity 81.

[0060] Furthermore, the embodiment of the utility model also provides a breast pump, comprising the above-mentioned milk suction assembly. By adopting the above-mentioned milk suction assembly, milk can be prevented from entering the negative pressure chamber 11 to contaminate the negative pressure chamber 11, or even affect the suction performance of the breast pump, thereby greatly improving the quality of the breast pump.

[0061] As an embodiment, the breast pump further includes a pump body and a solenoid valve, both of which are arranged in the main housing 100.
