[0165] As shown in Figures 1 to 3 and 7, the embodiment of the present application provides a milk pump assembly 10 for a breast pump 100, comprising a container body 11 and a sealing cover 12. The container body 11 and the sealing cover 12 enclose a milk storage chamber 111. In this way, milk can be temporarily stored in the milk storage chamber 111.

[0166] As an embodiment, referring to Figures 3 to 5, 8 and 9, the milk suction assembly 10 further includes a negative pressure member 13 and a milk guide member 14, both of which are connected to the sealing cover 12, the negative pressure member 13 having a negative pressure chamber 131, the negative pressure chamber 131 being used to connect to the negative pressure hole 311 of the breast pump 100, the milk guide member 14 having a milk guide channel 141, the milk guide channel 141 being connected to the negative pressure chamber 131, the milk guide channel 141 being at least used to guide milk from the breast; wherein, the negative pressure member 13, the milk guide member 14 and the sealing cover 12 are an integrally formed structure, and one of the milk guide channel 141 and the negative pressure chamber 131 is connected to the milk storage chamber 111.

[0167] By adopting the above technical solution, a milk guide member 14 having a milk guide channel 141 is provided, and the milk guide channel 141 is connected to the breast receiving cavity 21 for accommodating the breast, so that the milk sucked out of the breast can be guided; by providing a negative pressure member 13 having a negative pressure cavity 131, the negative pressure cavity 131 is connected to the milk guide channel 141, and the negative pressure cavity 131 can provide negative pressure for the milk guide channel 141, and then provide negative pressure for the breast receiving cavity 21 to achieve milk suction; by connecting one of the milk guide channel 141 and the negative pressure cavity 131 to the milk storage cavity 111, the milk can be transported to the In the milk storage chamber 111, by connecting the negative pressure piece 13 and the milk guide piece 14 to the sealing cover 12, and the negative pressure piece 13, the milk guide piece 14 and the sealing cover 12 are an integrally formed structure, that is, the negative pressure piece 13, the milk guide piece 14 and the sealing cover 12 are designed as a whole, the number of parts of the milk pumping assembly 10 is reduced, thereby reducing the difficulty of assembling the milk pumping assembly 10 and improving the assembly efficiency. In addition, there is no operation of assembling the negative pressure piece 13 and the milk guide piece 14 to the sealing cover 12, thereby avoiding the problem of poor air tightness caused by assembly errors of the negative pressure piece 13 and the milk guide piece 14. Therefore, the milk pumping assembly 10 provided in the embodiment of the present application has low assembly difficulty and high assembly efficiency, and avoids the occurrence of poor air tightness caused by assembly errors of the negative pressure piece 13 and the milk guide piece 14, eliminating the hidden danger of air tightness.

[0168] As an embodiment, the milk guide piece 14 and the negative pressure piece 13 are both connected to the side of the sealing cover 12 facing the milk storage chamber 111. In this way, the milk guide piece 14 and the negative pressure piece 13 are both accommodated in the milk storage chamber 111, that is, the milk guide channel 141 and the negative pressure chamber 131 are both accommodated in the milk storage chamber 111. This can effectively utilize the space in the milk storage chamber 111, reduce the assembly of external components of the milk suction assembly 10, and also facilitate the communication between the milk guide channel 141 and the negative pressure chamber 131 and the milk storage chamber 111. Of course, in specific applications, as an alternative embodiment, at least one of the milk guide piece 14 and the negative pressure piece 13 can also be connected to the side of the sealing cover 12 away from the milk storage chamber 111.

[0169] As an embodiment, referring to Figures 4, 5 and 9, the sealing cover 12 is provided with a first through-hole 121 and a second through-hole 122, wherein the central axis of the first through-hole 121 is parallel to the central axis of the second through-hole 122; the negative pressure member 13 is connected to the first through-hole 121, and the first through-hole 121 is used to connect the negative pressure chamber 131 with the negative pressure hole 311; the milk guide member 14 is connected to the second through-hole 122, and the second through-hole 122 is connected to the milk guide channel 141, for allowing milk to pass through and flow into the milk guide channel 141. In this way, the connection between the negative pressure member 13 and the milk guide member 14 and the sealing cover 12 is achieved, and milk can flow into the milk guide channel 141 and the negative pressure hole 311 can be connected to the negative pressure chamber 131. In addition, the first through-hole 121 is connected to the negative pressure chamber 131 , and the second through-hole 122 is connected to the milk conduction channel 141 , which also helps to clean the negative pressure chamber 131 through the first through-hole 121 and clean the milk conduction channel 141 through the second through-hole 122 .

[0170] Based on the previous embodiment, the central axis of the first through-hole 121 is coaxial with the central axis of the negative pressure chamber 131, and the central axis of the second through-hole 122 is coaxial with the central axis of the milk guide channel 141. In other words, the central axis of the negative pressure chamber 131 is parallel to the central axis of the milk guide channel 141. This allows the negative pressure member 13 and the milk guide member 14 to be arranged side by side on the side of the sealing cover 12 facing the milk storage chamber 111. Compared to a cross-arrangement of the milk guide member 14 and the negative pressure member 13, this reduces the space occupied by the container body 11, and thus reduces the space occupied by the milk pump assembly 10. Specifically, the central axis of the negative pressure chamber 131 and the central axis of the milk guide channel 141 are both perpendicular to the plane of the sealing cover 12, and the negative pressure member 13 and the milk guide member 14 are both perpendicular to the sealing cover 12.

[0171] In one embodiment, the first through-hole 121 and the second through-hole 122 are closely adjacent. The suction member 13 is connected to the first through-hole 121, and the milk guide member 14 is connected to the second through-hole 122. By closely arranging the first through-hole 121 and the second through-hole 122, the suction member 13 and the milk guide member 14 are tightly arranged together, thereby improving the compactness of the component arrangement of the milking assembly 10. It is understood that in other embodiments, the first through-hole 121 and the second through-hole 122 may not be closely adjacent.

[0172] As an embodiment, when the breast pump 100 is placed on the breast, the first through-hole 121 is located below the second through-hole 122. This facilitates positioning the negative pressure member 13 below the milk guide member 14, i.e., positioning the negative pressure chamber 131 below the milk guide channel 141. In a specific application, the milk guide channel 141 is located in the middle of the breast pump 100. Positioning the negative pressure chamber 131 below the milk guide channel 141 places the negative pressure chamber 131 slightly below the middle of the breast pump 100. This facilitates positioning the suction power generating device 321 (described below) at the bottom of the breast pump 100, thereby shifting the center of gravity of the breast pump 100 downward, making it easier for the breast pump 100 to fit snugly on the breast. Of course, in specific applications, when the breast pump 100 is placed on the breast, the first through-hole 121 may be positioned in other directions relative to the second through-hole 122, such as on the left, right, or top, etc.

[0173] In one embodiment, when the breast pump 100 is placed on the breast, the first through-hole 121 is located directly below the second through-hole 122, and the negative pressure chamber 131 is connected to the milk storage chamber 111. This facilitates positioning the negative pressure element 13 directly below the milk guide 14, thereby reducing the space occupied on the left and right sides of the container body 11 and improving the exterior profile of the container body 11. In this case, the negative pressure element 13 is configured as a three-way connection, connecting the negative pressure hole 311, the milk guide channel 141, and the milk storage chamber 111.

[0174] As one embodiment, as shown in Figures 5 to 7 , the container body 11 is provided with a first mounting groove 112. The sealing cover 12 is received within the first mounting groove 112 to enclose a milk storage chamber 111 with the container body 11. This prevents the sealing cover 12 from protruding from the opening of the container body 11, thereby reducing the thickness of the milk extraction assembly 10 and further reducing the thickness of the breast pump 100. Of course, in specific applications, as an alternative embodiment, the container body 11 may also be provided without the first mounting groove 112.

[0175] As an embodiment, the milk suction assembly 10 further includes a sealing member (not shown), which is provided between the sealing cover 12 and the container body 11 to seal the milk storage chamber 111 .

[0176] Furthermore, referring to Figures 7 to 9 , an embodiment of the present application also provides a breast pump 100, comprising a breast shield 20, a main unit 30, and the aforementioned milk pump assembly 10. The breast shield 20 is formed with a breast receiving cavity 21. The main unit 30 is provided with a negative pressure hole 311 for delivering negative pressure. A milk guide channel 141 is connected to the breast receiving cavity 21, and the negative pressure cavity 131 is connected to the negative pressure hole 311. By using the aforementioned milk pump assembly 10, the assembly efficiency of the milk storage device is improved, and the occurrence of poor airtightness caused by assembly errors between the negative pressure component 13 and the milk guide component 14 is reduced.

[0177] As one embodiment, as shown in Figures 4, 9, and 11, the sealing cover 12 defines a first through-hole 121. The negative pressure member 13 is connected to the first through-hole 121 and is located on the side of the sealing cover 12 facing the milk storage chamber 111. The breast pump 100 further includes an elastic diaphragm 40, which includes a diaphragm body 41 and a flange 42 connected to the diaphragm body 41. A second mounting groove 123 is defined around the negative pressure hole 311 of the main body 30 and / or around the first through-hole 121 of the sealing cover 12. The flange 42 is disposed within the second mounting groove 123, and the diaphragm body 41 is accommodated within the negative pressure chamber 131. This allows for the elastic diaphragm 40 to be installed without increasing the thickness of the breast pump 100, thereby facilitating a thinner design.

[0178] For example, in this embodiment, the sealing cover 12 is provided with a second mounting groove 123 around the first through-hole 121. The flange 42 of the elastic diaphragm 40 is mounted in the second mounting groove 123, and the diaphragm body 41 of the elastic diaphragm 40 is accommodated in the negative pressure chamber 131. This arrangement makes the installation of the elastic diaphragm 40 faster and more convenient.

[0179] As one embodiment, as shown in Figures 3, 8, and 9, the negative pressure member 13 further has a first through hole 132 and a second through hole 133. The first through hole 132 connects the negative pressure chamber 131 with the milk guide channel 141, and the second through hole 133 connects the negative pressure chamber 131 with the milk storage chamber 111. When the breast pump 100 is placed on the breast, the negative pressure chamber 131 is located below the milk guide channel 141. The elastic diaphragm 40 has a contracted state and a relaxed state. When the elastic diaphragm 40 is in the relaxed state, at least the portion of the elastic diaphragm 40 corresponding to the first through hole 132 is spaced from the wall of the negative pressure chamber 131. This arrangement allows for a certain amount of space between at least the portion of the elastic diaphragm 40 corresponding to the first through hole 132 and the wall of the negative pressure chamber 131 when the elastic diaphragm 40 is in the relaxed state. This space can accommodate milk, thereby preventing milk from flowing back into the milk guide channel 141 through the first through hole 132 when the elastic diaphragm 40 is in the relaxed state. A check valve (not shown) is provided at the second through hole 133 to prevent milk from flowing back from the milk storage chamber 111 into the negative pressure chamber 131 .

[0180] For example, in this embodiment, when the elastic diaphragm 40 is in the expanded state, the side of the elastic diaphragm 40 facing the first through hole 132 is tilted at a portion corresponding to the first through hole 132 , thereby forming a certain space.

[0181] As shown in Figures 8 to 10 , the main body 30 includes a first arm 31 and a second arm 32. The first arm 31 is sandwiched between the breastshield 20 and the milking assembly 10, and the second arm 32 is located on one side of the milking assembly 10. A negative pressure hole 311 is located on the side of the first arm 31 near the second arm 32. The second arm 32 includes a suction power generating device 321. The sealing cover 12 is located on the side of the container body 11 near the first arm 31. Specifically, when the breast pump 100 is placed on the breast, the second arm 32 is located below the milking assembly 10, with the first hole 121 located below the second hole 122. The negative pressure member 13 is located below the milking member 14, allowing the negative pressure generated by the suction power generating device 321 to be quickly transmitted to the negative pressure chamber 131. Furthermore, this arrangement can reduce the thickness of the breast pump 100, making it thinner.

[0182] As shown in Figures 12 to 14, the breast pump 100a provided in the embodiment of the present application includes a milk guide member 10a, a negative pressure member 20a and a main unit 30a; the milk guide member 10a is a component made of an optically transparent material, and has a milk guide channel 11a, which is at least used to guide milk from the breast; the negative pressure member 20a has a negative pressure cavity 21a, which is at least connected to the milk guide channel 11a; the main unit 30a is provided with a negative pressure hole 31a, which is connected to the negative pressure cavity 21a, and the main unit 30a generates negative pressure at the negative pressure hole 31a, and the negative pressure cavity 21a is connected to the negative pressure hole 31a and the milk guide channel 11a, so that negative pressure can be generated in the milk guide channel 11a; wherein, when the breast pump 100a is placed on the breast, the negative pressure member 20a is located below the milk guide member 10a, and the main unit 30a is located in other directions except above the milk guide member 10a.

[0183] The above technical solution is used to provide a milk guide member 10a having a milk guide channel 11a for conveying milk from the breast. By configuring the milk guide member 10a as a component made of an optically transparent material, the user can directly view the internal conditions of the milk guide channel 11a. By arranging the negative pressure member 20a below the milk guide member 10a and arranging the main unit 30a in a position other than above the milk guide member 10a, when using the breast pump 100a, the user can view the breast pump 100a from above, and neither the negative pressure member 20a nor the main unit 30a will block the milk guide member 10a. Therefore, the user can view the flow of milk in the milk guide channel 11a in real time. If the flow rate is too fast or too slow, the user can adjust the usage mode at any time to slow down or speed up the flow of milk. Therefore, when using the breast pump 100a provided by this embodiment, the user can quickly and effectively identify problems with the breast pump 100a and adjust the usage mode immediately, greatly improving the use effect of the breast pump 100a.

[0184] In one embodiment, at least a portion of the main unit 30a is located on the side of the negative pressure element 20a away from the milk guide 10a. That is, when the breast pump 100a is placed on the breast, at least a portion of the main unit 30a is located below the negative pressure element 20a. The milk guide channel 11a, which receives milk from the breast, is typically located in the center of the breast pump 100a. Specifically, the milk guide 10a is located in the center of the breast pump 100a. Positioning both the negative pressure element 20a and at least a portion of the main unit 30a below the milk guide 10a shifts the center of gravity of the breast pump 100a downward, facilitating a snug fit.

[0185] For example, in this embodiment, part of the main unit 30a is arranged on the side of the negative pressure member 20a away from the milk guide member 10a, and part of the main unit 30a is arranged beside the negative pressure member 20a and the milk guide member 10a.

[0186] In one embodiment, the negative pressure member 20a is made of an optically transparent material. In a specific application, when the negative pressure member 20a is disposed below the milk guide member 10a, it is configured as a three-way connection, communicating with the negative pressure hole 31a, the milk guide channel 11a, and the milk storage chamber 43a described below. The negative pressure chamber 21a also serves to guide milk. By configuring the negative pressure member 20a as an optically transparent material, the user can view the interior of the negative pressure chamber 21a, thereby allowing the user to check the condition of the milk within the negative pressure chamber 21a.

[0187] As shown in Figures 13 and 14 , a breast pump 100a further includes a milk storage container 40a. The milk guide 10a and the negative pressure element 20a are both connected to the inner side of the milk storage container 40a, and the main unit 30a is located outside the milk storage container 40a. Of course, in specific applications, as an alternative embodiment, the breast pump 100a can also be provided without the milk storage container 40a. In this case, the breast pump 100a can be connected to an external container such as a milk storage bag or a feeding bottle for storing milk.

[0188] In the previous embodiment, when the breast pump 100a is placed on the breast, at least the portion of the milk reservoir 40a located above the milk guide 10a is made of an optically transparent material. This allows the user to see the interior of the milk reservoir 40a and, during use, to peer through the milk reservoir 40a into the interior of the milk guide channel 11a.

[0189] In one embodiment, the entire milk storage container 40a is made of an optically transparent material. This allows the user to see the interior of the milk storage container 40a from all directions. Combined with the milk guide 10a and the negative pressure element 20a being made of transparent materials, the user can clearly see the entire process of milk being extracted from the nipple and transferred to the milk storage container 40a.

[0190] As one embodiment, referring to Figures 13 to 15 , a milk storage container 40a includes a first container wall 41a and a second container wall 42a, which together form a milk storage chamber 43a. The negative pressure member 20a and the milk guide 10a are both connected to the side of the second container wall 42a facing the milk storage chamber 43a. When the breast pump 100a is placed on the breast, the first container wall 41a is located above the milk guide 10a. Specifically, the first container wall 41a and the second container wall 42a each form a hollow cavity. When the first container wall 41a and the second container wall 42a are connected, the cavities of the two walls form the milk storage chamber 43a. Among them, the second container wall 42a is provided with a first through-hole 421a and a second through-hole 422a, and the first through-hole 421a and the second through-hole 422a are both connected to the milk storage chamber 43a; the milk guide piece 10a is connected to the first through-hole 421a, and the first through-hole 421a is used to connect the milk guide channel 11a with the outside of the milk storage container 40a so that milk can be guided to the milk guide channel 11a; the negative pressure piece 20a is connected to the second through-hole 422a, and the second through-hole 422a connects the negative pressure chamber 21a and the negative pressure hole 31a.

[0191] Based on the previous embodiment, the transparency of the first container wall 41a is greater than or equal to the transparency of the second container wall 42a. This helps the user to clearly view the interior of the milk storage container 40a when using the breast pump 100a.

[0192] As one embodiment, as shown in Figures 12 and 14 to 16 , a breast pump 100a further includes a breast shield 50a. The breast shield 50a includes a breast contact portion 51a and a channel portion 52a connected to the breast contact portion 51a. The breast contact portion 51a is configured to be attached to the breast. The channel portion 52a defines a nipple channel 521a. At least a portion of the channel portion 52a extends into the milk guide member 10a, connecting the nipple channel 521a with the milk guide channel 11a. Specifically, the channel portion 52a extends through the first perforation 421a and into the milk guide channel 11a of the milk guide member 10a. The nipple is accommodated in the nipple channel 521a. When milk is discharged from the nipple, it flows from the nipple channel 521a to the milk guide channel 11a.

[0193] In one embodiment, the channel portion 52a is made of an optically transparent material. This allows the user to see the interior of the nipple channel 521a. When wearing the breast pump 100a on the breast, the user can check whether the nipple is aligned with the nipple channel 521a and whether the nipple is accurately placed in the nipple channel 521a, thereby improving the wearing efficiency of the breast pump 100a on the breast.

[0194] In one embodiment, the breast-supporting portion 51a and the channel portion 52a are integrally formed. This reduces the number of assembly steps required for the breast shield 50a and effectively ensures a tight connection between the breast-supporting portion 51a and the channel portion 52a. Of course, in specific applications, as an alternative embodiment, the breast-supporting portion 51a and the channel portion 52a can be manufactured and assembled separately.

[0195] Based on the previous embodiment, the breast contact portion 51a is a component made of an optically transparent material.

[0196] As an embodiment, the channel portion 52a is interference-fitted with the milk guide piece 10a, so that the channel portion 52a and the milk guide piece 10a are connected conveniently and quickly.

[0197] As an embodiment, the breast shield 50a is detachably connected to the milk guide piece 10a. After breastfeeding is completed, the breast shield 50a can be disassembled from the milk guide piece 10a to facilitate cleaning of the breast shield 50a and the milk guide piece 10a.

[0198] As an embodiment, the outer surface of the channel portion 52a is smooth, which has a simple structure and is easy to manufacture.

[0199] As shown in FIG14 , the end of the channel portion 52a away from the breast contact portion 51a forms a step 60a with the inner surface of the milk guide 10a to prevent milk from flowing back. Specifically, when milk flows back, it hits the step 60a, which blocks the milk and prevents it from flowing further toward the breast contact portion 51.

[0200] As shown in Figures 17 and 22, an embodiment of the present application provides a milk pump assembly 10b for a breast pump 100b. The breast pump 100b can be worn on the breast, freeing the user's hands so that the user can do other things while using the breast pump 100b to express milk. The milk pump assembly 10b is at least used to extract milk.

[0201] 17 and 20 , the milk pump assembly 10b includes a container body 11b and a sealing cover 12b, which together form a milk storage chamber 111b, so that milk can be temporarily stored in the milk storage chamber 111b.

[0202] As an embodiment, referring to Figures 18 to 20, 23 and 24, the milk suction assembly 10b further includes a negative pressure member 13b and a milk guide member 14b; the negative pressure member 13b has a negative pressure chamber 131b, which is used to communicate with the negative pressure hole 311b of the breast pump 100b, and the negative pressure hole 311b provides negative pressure for the negative pressure chamber 131b; the milk guide member 14b has a milk guide channel 141b, which is connected to the negative pressure chamber 131b, and the milk guide channel 141b is at least used to guide milk from the breast; the milk guide member 14b and the negative pressure member 13b are arranged side by side in the breast pump 100b.

[0203] By adopting the above technical solution, a milk guide piece 14b having a milk guide channel 141b is provided, and the milk guide channel 141b is connected to the breast receiving cavity 21b for accommodating the breast, the milk sucked from the breast can be guided; by providing a negative pressure piece 13b having a negative pressure cavity 131b, and the negative pressure cavity 131b is connected to the milk guide channel 141b, the negative pressure cavity 131b can provide negative pressure for the milk guide channel 141b, and then provide negative pressure for the breast receiving cavity 21b, so as to achieve milk suction; by arranging the milk guide piece 14b and the negative pressure piece 13b side by side on the suction cup, the milk guide piece 14b and the negative pressure piece 13b can be connected to the breast receiving cavity 21b, so as to achieve milk suction; In the breast pump 100b, that is, the milk guide 14b and the negative pressure member 13b extend in the same direction, sufficient space is provided in the breast pump 100b in the same direction as the milk guide 14b and the negative pressure member 13b to accommodate the milk guide 14b and the negative pressure member 13b. Compared with the arrangement of the milk guide 14b and the negative pressure member 13b in a crosswise manner, the breast pump 100b provides sufficient accommodation space in two different extending directions of the milk guide 14b and the negative pressure member 13b. This effectively reduces the space occupied by the milk pump assembly 10b. Therefore, the milk pump assembly 10b provided in this embodiment occupies a small space, thereby reducing the overall volume of the breast pump 100b.

[0204] As an embodiment, the milk guide 14 and the negative pressure member 13 are connected side by side to the same surface of the sealing cover 12 and extend toward one side of the milk storage chamber 111. In this way, the space of the milk storage chamber 111b can be effectively utilized, reducing the assembly of external components of the milk suction assembly 10b.

[0205] As an embodiment, when the breast pump 100b is placed on the breast, the negative pressure member 13b is located below the milk guide member 14b. At this time, the negative pressure chamber 131b is located below the milk guide channel 141b. In a specific application, the milk guide channel 141b is located in the middle of the breast pump 100b. In this way, the negative pressure chamber 131b is located in the lower middle part of the breast pump 100b. Such an arrangement facilitates the placement of the suction power generating device 321b described below at the lower part of the breast pump 100b, thereby lowering the center of gravity of the breast pump 100b, making it more convenient for the breast pump 100b to be worn tightly on the breast. Of course, in a specific application, when the breast pump 100b is placed on the breast, the negative pressure member 13b can also be located in other positions of the milk guide member 14b, such as on the left, right, top, etc.

[0206] Building on the previous embodiment, when breast pump 100b is placed on the breast, negative pressure element 13b is located directly below milk guide element 14b, and negative pressure chamber 131b is connected to milk storage chamber 111b. This helps reduce the space occupied by the left and right sides of container body 11b and improves the external profile of container body 11b. In this case, negative pressure element 13b is configured as a three-way connection, connecting negative pressure hole 311b, milk guide channel 141b, and milk storage chamber 111b.

[0207] As an embodiment, referring to Figure 20, the milk guide piece 14b and the negative pressure piece 13b share a first side wall 132b; the opposite sides of the first side wall 132b face the negative pressure chamber 131b and the milk guide channel 141b respectively, and the first side wall 132b is penetrated by a first through hole 1321b that connects the negative pressure chamber 131b and the milk guide channel 141b. This arrangement simplifies the connection structure of the milk guide piece 14b and the negative pressure piece 13b, and improves production efficiency. Of course, in specific applications, as an alternative implementation scheme, the milk guide piece 14b and the negative pressure piece 13b are arranged at intervals, and the negative pressure chamber 131b and the milk guide channel 141b are connected by a connecting pipe.

[0208] In one embodiment, when the breast pump 100b is placed on the breast, the first through hole 1321b is located at the lowest point of the milk guide member 14b. Milk in the milk guide channel 141b flows out of the first through hole 1321b under the action of gravity. By locating the first through hole 1321b at the lowest point of the milk guide member 14b, milk in the milk guide channel 141b is ensured to flow out of the first through hole 1321b as much as possible, reducing milk accumulation in the milk guide channel 141b.

[0209] As shown in Figures 19, 21, 22, and 24, the negative pressure member 13b further includes a second side wall 133b and a first bottom wall 134b. The first side wall 132b, the second side wall 133b, and the first bottom wall 134b together form a negative pressure chamber 131b. A second through hole 1331b is formed through the second side wall 133b, connecting the negative pressure chamber 131b with the milk storage chamber 111b. When the breast pump 100b is placed on the breast, the second through hole 1331b is located below the first through hole 1321b. This arrangement allows milk to flow from the negative pressure chamber 131b to the milk storage chamber 111b. The first bottom wall 134b is positioned opposite the opening of the negative pressure chamber 131b, which is in communication with the negative pressure hole 311b.

[0210] In one embodiment, when the breast pump 100b is placed on the breast, the second through hole 1331b is located at the lowest point of the negative pressure member 13b. Milk in the negative pressure chamber 131b flows out through the second through hole 1331b under the action of gravity. By locating the second through hole 1331b at the lowest point of the negative pressure member 13b, milk in the negative pressure chamber 131b is ensured to flow out through the second through hole 1331b as much as possible, reducing milk accumulation in the negative pressure chamber 131b.

[0211] As an embodiment, when the breast pump 100b is placed on the breast, the second through hole 1331b and the first through hole 1321b are arranged vertically opposite each other; in this way, after the milk enters the negative pressure chamber 131b through the first through hole 1321b, it can directly enter the milk storage chamber 111b through the second through hole 1331b, thereby reducing the flow of milk in the negative pressure chamber 131b and thereby shortening the residence time of the milk in the negative pressure chamber 131b.

[0212] In another embodiment, when the breast pump 100b is placed on the breast, the second through-hole 1331b is located at one end of the second side wall 133b near the first bottom wall 134b. In a specific application, a diaphragm 40b is located within the negative pressure chamber 131b, and the diaphragm 40b has a contracted state and a relaxed state. When the diaphragm 40b within the negative pressure chamber 131b is in the relaxed state, it stretches from the opening of the negative pressure chamber 131b toward the first bottom wall 134b. By locating the second through-hole 1331b at the end of the second side wall 133b near the first bottom wall 134b, the diaphragm 40b can push milk toward the second through-hole 1331b during its expansion, facilitating milk flow out of the second through-hole 1331b and reducing milk accumulation within the negative pressure chamber 131b.

[0213] As an embodiment, the first bottom wall 134b and the first side wall 132b and the second side wall 133b are smoothly transitioned. In this way, a dead angle is avoided at the connection between the first bottom wall 134b, the first side wall 132b and the second side wall 133b, which helps to clean the negative pressure chamber 131b.

[0214] As an embodiment, as shown in Figure 19, the milk guide piece 14b also includes a third side wall 142b and a second bottom wall 143b. The first side wall 132b, the third side wall 142b and the second bottom wall 143b together form a milk guide channel 141b, and the second bottom wall 143b is arranged opposite to the entrance of the milk guide channel 141b.

[0215] On the basis of the previous embodiment, the second bottom wall 143b and the first side wall 132b and the third side wall 142b are smoothly transitioned. In this way, a dead angle is avoided at the connection between the second bottom wall 143b, the first side wall 132b and the third side wall 142b, which helps to clean the milk guide channel 141b.

[0216] As an embodiment, the length of the milk guide member 14b is the same as the length of the negative pressure member 13b. In a specific application, the milk guide member 14b and the negative pressure member 13b extend along the thickness direction of the breast pump 100b. By setting the length of the milk guide member 14b and the negative pressure member 13b to be the same, the thickness of the breast pump 100b is reduced, thereby avoiding the situation where the breast pump 100b is too thick due to one of the lengths being too long.

[0217] In one embodiment, the opening of the negative pressure chamber 131b, which communicates with the negative pressure port 311b, and the opening of the milk guide channel 141b, which receives milk, are arranged side by side and face the same direction. Thus, the main unit 30b of the breast pump 100b, where the negative pressure port 311b is located, and the breast shield 20b, which delivers milk to the milk guide channel 141b, are located on the same side of the milking assembly 10b. This makes the main unit 30b, breast shield 20b, and milking assembly 10b more compact, thus reducing the overall size of the device.

[0218] As an embodiment, referring to Figures 20, 21 and 24, the sealing cover 12b is provided with a first through-hole 121b and a second through-hole 122b, wherein the central axis of the first through-hole 121b is parallel or nearly parallel to the central axis of the second through-hole 122b, and the angle between the central axes of the two does not exceed 20°; the negative pressure member 13b is connected to the first through-hole 121b, and the first through-hole 121b is used to connect the negative pressure chamber 131b with the negative pressure hole 311b; the milk guide member 14b is connected to the second through-hole 122b, and the second through-hole 122b is connected to the milk guide channel 141b, for allowing milk to pass through and flow into the milk guide channel 141b. In this manner, the negative pressure member 13b and the milk guide member 14b are connected to the sealing cover 12b, and milk can flow into the milk guide channel 141b and the negative pressure hole 311b is connected to the negative pressure chamber 131b. Specifically, the central axis of the first through-hole 121b and the central axis of the second through-hole 122b are both perpendicular or nearly perpendicular to the plane where the sealing cover 12b is located, and the angle between the central axes of the two and the plane where the sealing cover 12b is located is in the range of 80° to 100°. The negative pressure piece 13b and the milk guide piece 14b are both perpendicular or nearly perpendicular to the sealing cover 12b, and the angle between the negative pressure piece 13b and the milk guide piece 14b and the sealing cover 12b is in the range of 80° to 100°.

[0219] Furthermore, referring to Figures 22 to 24 , this embodiment also provides a breast pump 100b, comprising a breast shield 20b, a main unit 30b, and the aforementioned milk extraction assembly 10b. The breast shield 20b includes a breast receiving cavity 21b; the main unit 30b is provided with a negative pressure hole 311b for transmitting negative pressure; a milk guide channel 141b communicates with the breast receiving cavity 21b, and a negative pressure cavity 131b communicates with the negative pressure hole 311b. The aforementioned milk extraction assembly 10b reduces the size of the breast pump 100b, making it easier for users to carry and use.

[0220] As shown in Figures 23 to 25 , the main body 30b includes a first arm 31b and a second arm 32b. The first arm 31b is sandwiched between the breast shield 20b and the milking assembly 10b, while the second arm 32b is located on one side of the milking assembly 10b. A negative pressure hole 311b is located on the side of the first arm 31b near the second arm 32b. The second arm 32b includes a suction power generating device 321b. Specifically, when the breast pump 100b is placed on the breast, the second arm 32b is located below the milking assembly 10b and, together with the negative pressure member 13b, below the milk guide member 14b. This allows the negative pressure generated by the suction power generating device 321b to be quickly transferred to the negative pressure chamber 131b. Furthermore, this arrangement can reduce the thickness of the breast pump 100b, making it thinner.

[0221] As an embodiment, referring to FIG. 24 and FIG. 25 , the breast pump 100b further includes a diaphragm 40b, which is connected to the sealing cover 12b and accommodated in the negative pressure chamber 131b. The diaphragm 40b is at least used to prevent milk from flowing into the negative pressure hole 311b.

[0222] The main unit of the breast pump is mainly used to provide negative pressure. In related technologies, due to the unreasonable structural design of the main unit and the large space occupied, the entire breast pump is too large, inconvenient to carry and use, and affects the user experience.

[0223] In view of this, an embodiment of the present application provides a breast pump with a rationally arranged main body structure, which effectively reduces the occupied space.

[0224] As shown in Figures 26 to 30, the breast pump 100c provided in an embodiment of the present application includes a main body housing 10c, a suction power device 20c and a milk suction assembly 30c; the main body housing 10c includes a first shell 12c and a second shell 13c bent and extended relative to the first shell 12c to form a step 14c on the main body housing 10c, and an accommodating chamber 11c is provided inside the main body housing 10c; the suction power device 20c is arranged in the accommodating chamber 11c for generating negative pressure; the milk suction assembly 30c is at least partially located on the step 14c.

[0225] The suction power device 20c is installed in the accommodating cavity 11c of the main body shell 10c. The main body shell 10c has a bearing and protection function for the suction power device 20c.

[0226] By adopting the above technical solution, by setting the second shell 13c to bend and extend relative to the first shell 12c, a step 14c is formed on the main body shell 10c, and the breast pump component 30c is at least partially located on the step 14c, so that the main body shell 10c and the breast pump component 30c are tightly assembled together, the layout is reasonable, and the space occupied by the main body shell 10c and the overall volume of the breast pump 100c are greatly reduced, thereby making the breast pump 100c easy to carry and use, and improving the user experience.

[0227] As one embodiment, as shown in Figures 29 to 31 , the main body housing 10c is L-shaped, with an L-shaped step 14c formed therein. The L-shaped main body housing 10c has a neat structure and occupies a small space. The L-shaped step 14c facilitates the assembly of the breast shield 32c and the milk collecting member 31c, allowing the various components of the breast pump 100c to be tightly assembled and arranged in a rational manner, effectively reducing the overall size of the breast pump 100c.

[0228] As shown in Figures 27, 28, and 31, a breast pump assembly 30c includes a milk collection member 31c and a breast shield 32c. The milk collection member 31c is disposed on one side of a first housing 12c, and a second housing 13c is disposed between the breast shield 32c and the milk collection member 31c. At least one of the first housing 12c and the second housing 13c has a cavity to form a receiving chamber 11c. The second housing 13c is sandwiched between the breast shield 32c and the milk collection member 31c to connect the breast shield 32c and the milk collection member 31c. The first housing 12c is disposed on one side of the milk collection member 31c, which can be the top, bottom, left, or right side. The terms "top, bottom, left, or right" refer to the orientation of the breast pump 100c when in operation.

[0229] On the basis of the previous embodiment, the milk collecting member 31c is supported on the first shell 12c; that is, the first shell 12c is arranged on the lower side of the milk collecting member 31c, that is, when the breast pump 100c is in use, the first shell 12c is located below the milk collecting member 31c. With this arrangement, the first shell 12c can support the milk collecting member 31c and improve the stability of the milk collecting member 31c. As an embodiment, referring to Figures 31 to 34, the first shell 12c has a first cavity 121c, the second shell 13c has a second cavity 131c, and the accommodating chamber 11c includes the first cavity 121c and the second cavity 131c. In this way, both the first cavity 121c and the second cavity 131c can accommodate components, thereby rationally arranging the suction power device 20c and minimizing the space occupied by the main housing 10c. Of course, in specific applications, the second cavity 131c may not be provided, and the first cavity 121c may form the accommodating cavity 11c, or the first cavity 121c may not be provided, and the second cavity 131c may form the accommodating cavity 11c.

[0230] Based on the previous embodiment, at least a portion of the suction power unit 20c is housed within the first cavity 121c. This reduces the volume of the second cavity 131c and, in turn, the thickness of the second housing 13c, thereby reducing the overall thickness of the breast pump 100c and making the breast pump 100c thinner.

[0231] As one embodiment, as shown in Figures 26, 31, and 36, the suction power unit 20c includes an air pump 21c, a solenoid valve 22c, a battery 23c, and a circuit board (not shown). The air pump 21c, solenoid valve 22c, and battery 23c are housed within the first cavity 121c, and the circuit board is housed within the second cavity 131c. Thus, most of the weight of the suction power unit 20c is concentrated within the first cavity 121c. When the breast pump 100c is in use and the first housing 12c is located below the milk collecting member 31c, the center of gravity of the entire breast pump 100c is biased downward, thereby improving the sealing performance of the breast pump 100c when worn. Furthermore, since most of the components of the suction power unit 20c are installed within the first cavity 121c, the volume of the second cavity 131c and the thickness of the second housing 13c can be reduced, thereby making the entire breast pump 100c thinner.

[0232] In specific applications, according to needs, any one or two of the suction pump 21c, the solenoid valve 22c and the battery 23c can be placed in the second cavity 131c, or the circuit board can be placed in the first cavity 121c.

[0233] The battery 23c is electrically connected to the circuit board, which is in turn electrically connected to both the air pump 21c and the solenoid valve 22c. When the air pump 21c is operating, the solenoid valve 22c is inoperative, allowing the air pump 21c to draw air away and create negative pressure. When the solenoid valve 22c is operating, the air pump 21c is inoperative, opening the solenoid valve 22c and allowing air to flow into the milk collection assembly 312c of the milk collection member 31c.

[0234] Based on the previous embodiment, the air pump 21c, battery 23c, and solenoid valve 22c are arranged side by side, with battery 23c located between the air pump 21c and the solenoid valve 22c. Both the air pump 21c and the solenoid valve 22c generate heat during operation. By placing battery 23c between them, they are isolated and prevent localized overheating. Of course, in specific applications, as alternative implementations, the air pump 21c can be located between the battery 23c and the solenoid valve 22c, or the solenoid valve 22c can be located between the battery 23c and the air pump 21c.

[0235] As an embodiment, referring to Figures 29, 31 and 33, the first shell 12c includes a first surface shell 122c and a first bottom shell 123c, and the first surface shell 122c and the first bottom shell 123c form a first cavity 121c; the second shell 13c includes a second surface shell 132c and a second bottom shell 133c, and the second surface shell 132c and the second bottom shell 133c are enclosed to form a second cavity 131c; the first surface shell 122c and the second surface shell 132c are perpendicular or nearly perpendicular to each other and are located on both sides of the milk collecting member 31c.

[0236] As an embodiment, referring to Figures 29, 30, 33, and 34, a negative pressure hole 134c is provided on the side of the second shell 13c where the first shell 12c is provided. The negative pressure hole 134c is connected to the second cavity 131c. In other words, a negative pressure hole 134c is provided on the side of the second shell 13c facing the milk collection component 31c, that is, the second surface shell 132c is provided with a negative pressure hole 134c. In a specific application, the suction pump 21c and the solenoid valve 22c are connected to one end of the air duct, and the other end of the air duct is connected to the negative pressure hole 134c or is provided through the negative pressure hole 134c. The negative pressure hole 134c can provide negative pressure or transmit air to the milk suction component 312c of the milk collection component 31c. The provision of the negative pressure hole 134c on the second surface shell 132c facilitates the provision of negative pressure or the transmission of air to the milk suction component 312c of the milk collection component 31c.

[0237] Building on the previous embodiment, negative pressure port 134c is located at the end of the second housing 13c near the first housing 12c. The air pump 21c and solenoid valve 22c are both located within the first cavity 121c of the first housing 12c. One end of the air duct connects the air pump 21c and the solenoid valve 22c, while the other end of the air duct connects to or passes through negative pressure port 134c. Placing negative pressure port 134c at the end of the second housing 13c near the first housing 12c shortens the air duct and improves the neatness of the accommodating cavity 11c.

[0238] As one embodiment, the breast pump 100c also includes a keypad unit, which is located around the second housing 13c, excluding the end near the first housing 12c. This location of the keypad unit facilitates user operation. The keypad unit is electrically connected to the circuit board. By operating various keys on the keypad unit, parameters such as pumping frequency, single pumping duration, and suction force can be adjusted, as well as the device can be turned on or off, thereby meeting the diverse breastfeeding needs of different users.

[0239] Building on the previous embodiment, the key unit is located at the end of the second housing 13c away from the first housing 12c. When the breast pump 100c is in use, the first housing 12c is located at the bottom of the breast pump 100c, and the end of the second housing 13c away from the first housing 12c is located at the top of the breast pump 100c. Positioning the key unit at the end of the second housing 13c away from the first housing 12c, that is, at the top of the breast pump 100c, makes key operation more convenient for the user.

[0240] As one embodiment, as shown in Figures 29 and 30 , the second housing 13c further includes a through hole 135c extending from the side of the second housing 13c distal to the first housing 12c to the side proximal to the first housing 12c. Through hole 135c is configured to receive a breast shield 32c. The provision of through hole 135c connects the breast shield 32c and the milk collecting member 31c on either side of the second housing 13c. In practice, the breast shield 32c includes a breast-mounting portion and a nipple passage, with through hole 135c corresponding to the nipple passage for receiving the nipple.

[0241] As one embodiment, as shown in Figures 29, 30, and 33, a limiting groove 124c is provided on the side of the first housing 12c where the second housing 13c is provided. In other words, the limiting groove 124c is provided on the side of the first housing 12c facing the milk collecting member 31c, that is, the first surface shell 122c forms the limiting groove 124c. The limiting groove 124c is used to limit the position of the milk collecting member 31c, thereby improving the installation stability of the milk collecting member 31c.

[0242] As shown in Figures 28 and 29 , the milk collection member 31c includes a milk storage container 311c and a milk suction assembly 312c extending within the container. The suction power unit 20c is used to provide negative pressure to the milk suction assembly 312c. The milk suction assembly 312c extends within the milk storage container 311c, making the milk collection member 31c compact and reducing the overall size of the breast pump 100c.

[0243] In the related art, breast pumps use heat sinks to dissipate heat from the main unit. Since the heat sinks are mostly sheet structures made of aluminum alloy, brass or bronze, and in order to improve the heat dissipation effect, multiple heat sinks need to be assembled, which makes the breast pump larger in size and weight, greatly reducing the user experience.

[0244] In view of this, an embodiment of the present application provides a breast pump that uses breast milk to dissipate heat from the main body and does not require a separate heat sink.

[0245] As shown in FIG35 and FIG36 , the breast pump 100d provided in the embodiment of the present application includes a main unit 10d and a milk storage container 20d. The main unit 10d is used to provide negative pressure, and the milk storage container 20d is used to store the expressed milk.

[0246] During use, the main unit 10d generates negative pressure, and the milk suction component of the breast pump 100d sucks milk from the user's breast through the negative pressure and guides the milk into the milk storage container 20d for temporary storage.

[0247] As one embodiment, as shown in Figures 36 and 37 , a milk storage container 20d includes a supporting wall 21d and a surrounding wall 22d. The supporting wall 21d and the surrounding wall 22d together form a milk storage cavity (not shown). The supporting wall 21d is used to hold milk flowing into the milk storage cavity. In a specific application, the milk is temporarily stored in the milk storage cavity of the milk storage container 20d. When the breast pump 100d is in use, the supporting wall 21d is located below the surrounding wall 22d. Once milk enters the milk storage cavity, it flows toward the supporting wall 21d under the action of gravity and is held above the supporting wall 21d.

[0248] As shown in Figures 36 and 37 , at least a portion of the main unit 10d is attached to the side of the support wall 21d facing away from the milk storage chamber. That is, when the breast pump 100d is in use, at least a portion of the main unit 10d is located below the support wall 21d and is positioned in contact with the support wall 21d. As milk flows into the milk storage chamber and down to the support wall 21d, where it is held by the support wall 21d, the milk absorbs heat from the main unit 10d, dissipating heat. This eliminates the need for heat sinks, significantly reducing the overall size and weight of the device and improving the user experience. Furthermore, the main unit 10d is positioned below the milk storage container 20d, providing some support for the container.

[0249] As shown in Figures 37 to 40 , a main unit 10d includes a first bottom shell 11d, a first front shell 12d, and an air pump 13d. The first bottom shell 11d and the first front shell 12d enclose a first accommodating chamber 14d, within which the air pump 13d is housed. The first front shell 12d is attached to the side of the supporting wall 21d facing away from the milk storage chamber. The air pump 13d generates a significant amount of heat during operation. This arrangement allows milk to absorb the heat from the air pump 13d, dissipating the heat and cooling the air pump 13d, effectively extending its service life.

[0250] The first shell 12d is made of a material with a certain strength and good thermal conductivity, such as thermally conductive plastic. In this way, the first shell 12d can not only well support the milk storage container 20d, but also efficiently transfer heat.

[0251] As an embodiment, the projection of the first shell 12d toward the support wall 21d lies within the outline of the support wall 21d. This allows the entire first shell 12d to be attached to the support wall 21d, maximizing the heat transfer area of ​​the first shell 12d and improving heat transfer efficiency. In this embodiment, the projection of the first shell 12d toward the support wall 21d completely overlaps with the outline of the support wall 21d.

[0252] As an embodiment, the thickness of the first housing 12d is less than that of the first bottom housing 11d. Setting the thickness of the first housing 12d to be smaller helps increase its thermal conductivity; while setting the thickness of the first bottom housing 11d to be larger greatly enhances its support performance. Of course, in specific applications, as an alternative embodiment, the thickness of the first housing 12d can also be the same as that of the first bottom housing 11d.

[0253] As one embodiment, as shown in Figures 35, 38, and 41, the first housing 12d includes at least two panels 121d, with any two adjacent panels 121d arranged at an angle less than 180°. This arrangement increases the surface area of ​​the first housing 12d per unit area of ​​the breast pump 100d, thereby increasing the heat transfer area per unit area of ​​the breast pump 100d, thereby improving heat transfer efficiency.

[0254] Based on the previous embodiment, the angle ranges from 90° to 170°. In specific applications, the angle can be set according to needs, such as 100°, 130°, or 150°. For example, in this embodiment, the angle is set to 120°.

[0255] As shown in Figure 42 , panel 121d is configured as a flat surface. This simplifies the process and facilitates manufacturing. In another embodiment, panel 121d can also be configured as a non-flat surface. This further increases the surface area of ​​first housing 12d and improves thermal conductivity. As shown in Figures 43 and 44 , panel 121d can be wavy or have other shapes, and the shape of panel 121d is not limited herein.

[0256] In one embodiment, adjacent panels 121d have a smooth transition. This prevents blind spots from forming between the panels 121d, allowing the first accommodating chamber 14d to effectively accommodate components and increase the capacity of the first accommodating chamber 14d. Furthermore, the support wall 21d is closely aligned with the first housing 12d, preventing blind spots from forming on the support wall 21d, facilitating cleaning of the milk storage container 20d.

[0257] As an embodiment, as shown in Figures 36 and 41, at least two panels 121d form a limiting groove 122d, which is used to limit the position of the milk storage container 20d. In a specific application, the limiting groove 122d limits the left and right directions of the milk storage container 20d.

[0258] In one embodiment, the suction pump 13d corresponds to the bottom wall of the limiting groove 122d. That is, the position of the first accommodating chamber 14d accommodating the suction pump 13d corresponds to the bottom wall of the limiting groove 122d. Milk flows to the lowest point of the supporting wall 21d under the action of gravity. The lowest point of the supporting wall 21d is aligned with the bottom wall of the limiting groove 122d. This ensures that heat from the suction pump 13d can still be dissipated during the initial stage of milk flowing into the milk storage chamber or when the amount of milk is small.

[0259] In one embodiment, one of the first housing 12d and the supporting wall 21d is provided with an anti-detachment slot, and the other is provided with an anti-detachment projection, which is snapped into the anti-detachment slot. The interlocking assembly of the anti-detachment projection and the anti-detachment slot enhances the connection strength between the first housing 12d and the supporting wall 21d, ensuring that the milk storage container 20d is unlikely to become loose or even fall off the main unit 10d if accidentally pulled by external forces.

[0260] For example, in this embodiment, an anti-dropout protrusion is provided on a side of the first shell 12d away from the first accommodating chamber 14d, and an anti-dropout groove is provided on a side of the supporting wall 21d away from the milk storage chamber.

[0261] It should be noted that the anti-dropout protrusion can optionally be a spherical protrusion, and the corresponding anti-dropout groove can be a spherical groove with a spherical bottom wall. This effectively prevents the milk storage container 20d from moving horizontally. Alternatively, the anti-dropout protrusion can optionally be a slide rail structure with a "T"-shaped cross-section, and the corresponding anti-dropout groove can be a slide groove structure with a "T"-shaped cross-section. In this way, the milk storage container 20d can be slidably mounted on the main unit 10d via the slide rail structure, thereby restricting the milk storage container 20d from moving vertically.

[0262] In one embodiment, the main unit 10d further includes a solenoid valve 15d. The suction pump 13d and the solenoid valve 15d are housed side by side within the first accommodating chamber 14d. The solenoid valve 15d generates heat during operation. By placing the solenoid valve 15d within the first accommodating chamber 14d, milk can dissipate heat from the solenoid valve 15d.

[0263] As one embodiment, as shown in Figures 40 and 45 , the main unit 10d further includes a second housing 16d and a second bottom housing 17d. The second housing 16d and the second bottom housing 17d enclose a second accommodating chamber 18d, and the first accommodating chamber 14d and the second accommodating chamber 18d are interconnected. The main unit 10d further includes a battery 19d and a control board (not shown). The battery 19d is housed in the first accommodating chamber 14d, and the control board is housed in the second accommodating chamber 18d. The battery 19d and the control board are electrically connected, and the suction pump 13d and the solenoid valve 15d are both electrically connected to the control board.

[0264] The battery 19d, the air pump 13d and the solenoid valve 15d are arranged side by side in the first accommodating chamber 14d, wherein, as shown in Figures 40, 41 and 45, the air pump 13d can be arranged between the battery 19d and the solenoid valve 15d, corresponding to the bottom wall of the limiting groove 122d, or the battery 19d can be arranged between the air pump 13d and the solenoid valve 15d, thereby separating the two components that both generate heat.

[0265] FIG46 shows a schematic structural diagram of a breast pumping device according to an embodiment of the present application.

[0266] Referring to FIG46 , an embodiment of the present application provides a breast pump device, comprising a breast pump 10e and a dust cover 20e with a charging function. The dust cover 20e can be used in conjunction with the breast pump 10e. The breast pump 10e has an opening for covering the breast to collect milk. When the breast pump 10e is not in use or is low on power, the dust cover 20e can cover the opening to protect it from dust, bacteria, etc., and prevent it from entering the breast pump 10e through the opening. The dust cover 20e can also be used to charge the breast pump 10e. When the breast pump 10e is needed, the dust cover 20e can be removed to allow normal use. The breast pump 10e primarily comprises a main unit and a milk bowl. The milk bowl is used to store milk, while the main unit is used to generate negative pressure during operation to draw milk into the milk bowl.

[0267] When the dust cover 20e is installed on the breast pump 10e, the dust cover 20e can cover the opening of the breast pump 10e, thereby preventing dust, bacteria, etc. from entering the breast pump and preventing the milk in the breast pump 10e from being contaminated and deteriorated. The breast pump 10e can also be charged as needed without increasing the volume of the breast pump 10e, taking into account the milk capacity and battery life performance of the breast pump 10e, thereby ensuring the portability and user experience of the breast pump 10e.

[0268] Figure 47 shows a cross-sectional view of a breast pump according to an embodiment of the application; Figure 48 shows a schematic diagram of a structural decomposition of the breast pumping device according to an embodiment of the application; and Figure 49 shows another schematic diagram of a structural decomposition of the breast pumping device according to an embodiment of the application.

[0269] As specifically shown in Figures 47 to 49, this embodiment provides a dust cover 20e with a charging function. The dust cover 20e mainly includes a cover body 21e and a charging component 22e. A accommodating cavity 200e is formed inside the cover body 21e, which is used to be installed on the breast pump 10e to cover the opening of the breast pump 10e; the charging component 22e is at least partially arranged in the accommodating cavity 200e. The charging component 22e is used to charge the breast pump 10e when the cover body 21e is installed on the breast pump 10e, so as to work when the battery in the breast pump 10e needs to be replenished with power, thereby improving the battery life performance of the breast pump 10e.

[0270] In one embodiment, the side of the cover 21e facing the opening of the breast pump 10e has a raised tapered portion 23e and a circle of accommodating portions 24e recessed outside the tapered portion 23e. The tapered portion 23e is used to extend into the opening of the breast pump 10e, and the accommodating portion 24e is used to accommodate at least part of the breast pump 10e.

[0271] In some embodiments, the receiving portion 24e may also be omitted.

[0272] To ensure a better fit, the surface of the breast pump 10e facing the body has a breast shield 101e. An opening is formed in the breast shield 101e. The breast shield 101e is typically made of a soft material, such as silicone, to ensure a good fit. When the breast pump 10e is in operation, milk flows through the opening in the breast shield 101e into the milk bowl.

[0273] Because the outer circumference of the tapered portion 23e is an inclined frustum with a convex center, the radial dimension of the outer circumference of the tapered portion 23e gradually decreases as it moves away from the receiving portion 24e of the dust cover 20e. During installation of the dust cover 20e onto the breast pump 10e, the tapered portion 23e can mate with the opening of the breast pump 10e, guiding the dust cover 20e to be accurately and quickly installed thereon. Once the dust cover 20e is installed onto the breast pump 10e, the end of the breast shield 101e is accommodated within the receiving portion 24e, and the sidewalls of the receiving portion 24e surround the breast shield 101e, achieving a reliable seal and dustproofing effect.

[0274] In one embodiment, the side wall of the accommodating portion 24e may also be provided with a protrusion for engaging with the edge of the breast shield 101e. For example, the protrusion may be a claw or a limiting edge, and the breast shield 101e is constrained between the bottom surface of the accommodating portion 24e and the protrusion and will not easily fall out.

[0275] Specifically, the breast pump 10e includes a built-in second battery 12e, which provides power to the main unit of the breast pump 10e. The charging assembly 22e includes an interface module 221e and a power source. The interface module 221e serves as a power output interface, electrically connecting the breast pump 10e when the housing 21e is mounted on the breast pump 10e. The power source is electrically connected to the interface module 221e and can be a battery or an external power source.

[0276] In this way, the dust cover 20e can be used as a power bank. The dust cover 20e can also be conveniently removed from the breast pump 10e for charging when not in use. In addition, the breast pump 10e can also be charged using its own charger.

[0277] For example, the power source is a first battery 222e, which is connected to the interface module 221e and is used to provide DC power to the interface module 221e. This allows the interface module 221e to recharge the second battery 12e within the breast pump 10e after the dust cover 20e is attached to the breast pump 10e. It is understood that in other embodiments, the charging assembly 22e may also include a power conversion module (not shown) connected to the interface module 221e and configured to connect to an external power source (e.g., mains electricity or a high-voltage power source) to convert external AC power to DC power, which is then supplied to the interface module 221e. Alternatively, the power conversion module may convert a high-voltage external voltage to a suitable low-voltage DC power, which is then supplied to the interface module 221e. In this manner, the dust cover 20e can function as a charger, eliminating the need for a separate charger and reducing component count. In another embodiment, the charging component 22e may include both a power conversion module and a second battery 12e. The power conversion module and the second battery 12e are respectively connected to the interface module 221e. The user can freely choose to use the charging component 22e or an external power supply to charge the breast pump 10e as needed.

[0278] The power conversion module and the first battery 222e may both be disposed in the accommodating cavity 200e, and the interface module 221e may be at least partially disposed in the accommodating cavity 200e.

[0279] 47 to 449 , this embodiment illustrates how the interface module 221e and the breast pump 10e utilize conductive terminals for electrical contact. Specifically, the interface module 221e includes a first conductive terminal, and the breast pump 10e includes a second conductive terminal 11e. The first conductive terminal is configured to electrically contact the second conductive terminal 11e when the cover 21e is mounted on the breast pump 10e.

[0280] Specifically, the first conductive terminal is a conductive pin protruding from the housing 21e. A recess (not shown) is formed on the breast pump 10e, and the second conductive terminal 11e is embedded in the recess. When the housing 21e is attached to the breast pump 10e, the conductive pin can extend into the recess to contact the second conductive terminal 11e, thereby transmitting electrical energy.

[0281] In one embodiment, the conductive needle is an elastic pin that can be extended and retracted in the axial direction. In the natural state, the conductive needle is in an extended state and can elastically contact the second conductive terminal 11e, thereby ensuring the contact and conductive reliability between the conductive needle and the second conductive terminal 11e.

[0282] Since the second conductive terminal 11e is embedded in the recess and does not protrude from the breast pump 10e, the user will not touch the protruding second conductive terminal 11e when holding the breast pump 10e or attaching the breast pump 10e to the body, thereby avoiding affecting the feel of use and improving user comfort.

[0283] Alternatively, the recess may be shaped like a flared trumpet, allowing the first conductive terminal to slide along the surface of the trumpet-shaped recess until it contacts and electrically connects with the second conductive terminal 11e. Alternatively, the end of the second conductive terminal 11e may be formed with a slot for the first conductive terminal to plug into, allowing the first conductive terminal to be inserted into the slot of the second conductive terminal 11e to achieve electrical connection.

[0284] It is understandable that, in other embodiments, the contact and conductive method between the interface module 221e and the breast pump 10e is not limited to this. For example, contact points may be provided on the interface module 221e and the breast pump 10e respectively, and the interface module 221e and the breast pump 10e may be in contact with each other through their respective contact points, thereby achieving contact and conductive method between the interface module 221e and the breast pump 10e.

[0285] In one embodiment, the cover body 21e is L-shaped and includes a main body 211e and a base 212e connected to one end of the main body 211e. The main body 211e is configured to cover the opening of the breast pump 10e, and the base 212e is configured to support the breast pump 10e. Exemplarily, the main body 211e and the connecting main body 211e are perpendicular to each other. After the dust cover 20e is attached to the breast pump 10e, the entire breast pump 10e can be supported on the base 212e, with the opening of the breast pump 10e facing the main body 211e and covered by the main body 211e. The bottom of the breast pump 10e can be flat, and the surface of the base 212e can also be flat, so that the breast pump 10e can be securely fixed to the surface of the base 212e. In other embodiments, the bottom of the breast pump 10e can also be non-flat, such as a curved surface, so that the surface of the base 212e can adapt to the shape of the bottom of the breast pump 10e. As shown in FIG49 , the first conductive terminal of the interface module 221e can be disposed on the base portion 212e, that is, on the upper surface of the base portion 212e, and the second conductive terminal 11e is disposed on the bottom of the breast pump 10e, thereby avoiding the first conductive terminal being disposed on the main body portion 211e and causing the second conductive terminal 11e to face the human body and come into contact with the human body.

[0286] It is understood that in other embodiments, the first conductive terminal of the interface module 221e may not be located on the surface of the base portion 212e facing the bottom of the breast pump 10e. For example, the interface module 221e may be located on a first surface of the cover 21e, the first surface being adjacent to a surface of the cover 21e facing the opening of the breast pump 10e. For example, the first conductive terminal may be located on a side portion of the main body 211e or the base portion 212e, extending toward the outer circumference of the breast pump 10e. It is sufficient that the second conductive terminal 11e on the breast pump 10e corresponds to the position of the first conductive terminal.

[0287] It should be understood that the power transmission method between the interface module 221e and the breast pump 10e is not limited to contact-based electrical conduction; a non-contact method of power transmission is also possible. For example, in one embodiment, the interface module 221e includes a first induction coil, and the breast pump 10e includes a second induction coil. When the cover 21e is installed on the breast pump 10e, power can be transmitted between the first and second induction coils, achieving wireless charging. By configuring the power transmission method between the interface module 221e and the breast pump 10e as non-contact conductive, the breast pump 10e eliminates the need for holes corresponding to the power terminals on its surface, eliminating the need for protruding power terminals. This ensures both an aesthetically pleasing appearance and an improved feel. For example, the first induction coil can be positioned within the accommodating cavity 200e, corresponding to the tapered portion 23e, to facilitate power transmission between the first induction coil and the second induction coil.

[0288] Figure 50 shows a schematic structural diagram of a breast pumping device according to an embodiment of the present application; Figure 51 shows a schematic cross-sectional structural diagram of a dust cover according to an embodiment of the present application.

[0289] Referring to Figures 50 and 51 , an embodiment of the present application provides a breast pump device, comprising a breast pump 10f and a dust cover 20f. The dust cover 20f can be used in conjunction with the breast pump 10f. The breast pump 10f has a milk collection opening for covering the breast to collect milk. When the breast pump 10f is not in use, the dust cover 20f can cover the milk collection opening of the breast pump 10f to protect it and prevent dust, bacteria, etc. from entering the breast pump 10f through the milk collection opening. The dust cover 20f can also be used to preheat the breast pump 10f. When the breast pump 10f is needed, the dust cover 20f can be removed to allow normal use.

[0290] As shown in Figure 51, an embodiment of the present application provides a dust cover 20f. The dust cover 20f includes a cover body 21f and a heating assembly 22f. The cover body 21f is configured to be mounted on a breast pump 10f to cover the milk collection opening of the breast pump 10f. The cover body 21f defines an installation space 200f, and an air outlet 201f is formed on the cover body 21f, communicating with the installation space 200f. The heating assembly 22f is disposed within the installation space 200f and configured to heat the air within the installation space 200f. The air heated by the heating assembly 22f within the dust cover 20f can be discharged through the air outlet 201f, thereby preheating the breast pump 10f and preventing the milk collection opening of the breast pump 10f from becoming too cold and causing discomfort upon contact with the human body.

[0291] When using the breast pump 10f, it is necessary to first remove the dust cover 20f, then attach the milk collection opening to the human body, and operate the breast pump 10f to use negative pressure to suck milk from the breast. The milk enters the breast pump 10f through the milk collection opening and is stored.

[0292] It is understandable that the breast pump 10f can be a manual breast pump or an electric breast pump. In one embodiment, the breast pump 10f is an electric breast pump, which also includes a main unit, which is used to generate negative pressure during operation to suck out milk.

[0293] Through the above arrangement, the dust cover 20f of this embodiment can be installed on the milk collection opening of the breast pump 10f to protect the breast pump 10f and prevent bacteria, dust, etc. from entering the breast pump 10f. Moreover, since a heating component 22f is provided in the dust cover 20f, when the dust cover 20f is installed on the breast pump 10f, the hot air generated in the dust cover 20f can preheat the breast pump 10f, thereby preventing the cold breast pump 10f from directly contacting the human breast, thereby improving the user experience.

[0294] For example, in winter or in cold weather, when the breast pump 10f needs to be used, the dust cover 20f can be installed on the breast pump 10f and the heating component 22f can be started to heat the air in the dust cover 20f. The hot air is discharged from the air outlet 201f to preheat the breast pump 10f (especially the milk collection opening). After the preheating is completed, the milk collection opening is no longer cold, the dust cover 20f can be removed, and the breast pump 10f can be started for use.

[0295] Specifically, the dust cover 20f can include a battery 28f, which is disposed within the installation space 200f and electrically connected to the heating assembly 22f to provide electrical energy for the heating assembly 22f. It is understood that the dust cover 20f can also be provided without the battery 28f, and instead an external power source can be used to power the heating assembly 22f. For example, a power supply interface or plug can be provided on the cover body 21f, and power can be supplied by connecting the external power source to the power supply interface or plug.

[0296] As shown in Figures 51 and 52, in one embodiment, the cover body 21f includes an air inlet 202f in addition to the air outlet 201f. The air inlet 202f and the air outlet 201f are respectively connected to the installation space 200f. External air can enter the installation space 200f through the air inlet 202f, be heated by the heating component 22f, and then flow out from the air outlet 201f. In order to accelerate the discharge of hot air in the installation space 200f, the dust cover 20f also includes a convection fan 23f. The convection fan 23f is arranged in the installation space 200f and is used to draw external air into the installation space 200f through the air inlet 202f and blow the air heated by the heating component 22f out of the air outlet 201f. In this way, external air can be quickly inhaled and the heated air can be quickly discharged.

[0297] In one embodiment, the heating assembly 22f includes a first heating element 221f, which is disposed between the air inlet 202f and the convection fan 23f. Specifically, the first heating element 221f is located upstream of the convection fan 23f. External air entering the air inlet 202f is first heated by the first heating element 221f and then drawn toward the air outlet 201f by the convection fan 23f. During this process, hot air enters the convection fan 23f.

[0298] In one embodiment, the heating assembly 22f may include a second heating element 222f, which is disposed between the convection fan 23f and the air outlet 201f. Specifically, the second heating element 222f is located downstream of the convection fan 23f. External air entering the air inlet 202f is first drawn in by the convection fan 23f and then supplied to the second heating element 222f. The hot air heated by the second heating element 222f is then blown out toward the air outlet 201f by the convection fan 23f. During this process, the external air entering the convection fan 23f is at room temperature.

[0299] It is understood that, in another embodiment, the heating assembly 22f may include at least two heating elements. For example, the heating assembly 22f includes the first heating element 221f and the second heating element 222f described above. The first heating element 221f is disposed between the air inlet 202f and the convection fan 23f, and the second heating element 222f is disposed between the convection fan 23f and the air outlet 201f. Under the action of the convection fan 23f, outside air is sucked in from the air inlet 202f, and after being heated by the first heating element 221f, is blown out toward the second heating element 222f by the convection fan 23f. The second heating element 222f further heats the hot air heated by the first heating element 221f, and the heated air is blown out of the air outlet 201f under the action of the convection fan 23f.

[0300] In one embodiment, the heating assembly 22f includes at least one heating element; the at least one heating element is a heating plate, and / or the at least one heating element is a heating wire, and / or the at least one heating element is a heating mesh. In other words, the first heating element 221f and the second heating element 222f can be selected from the following three types of heating elements: a heating plate, a heating wire, and a heating mesh. The first heating element 221f and the second heating element 222f can be the same type of heating element or different types of heating elements. The heating assembly 22f can also include more than two heating elements.

[0301] As shown in Figures 51 and 52, the first heating element 221f is a heating wire and the second heating element 222f is a heating plate. The first heating element 221f, the convection fan 23f, and the second heating element 222f are sequentially arranged within the installation space 200f along the airflow direction. The second heating element 222f is an annular heating plate with an airflow channel formed in the middle thereof and connected to the air outlet 201f. The air blown toward the second heating element 222f by the convection fan 23f is heated by the second heating element 222f and then flows out of the air outlet 201f through the airflow channel in the middle of the second heating element 222f.

[0302] Specifically, the dust cover 20f also includes a cylindrical guide housing 24f installed within the installation space 200f. The convection fan 23f is disposed within the guide housing 24f, with the ends of the guide housing 24f facing the air inlet 202f and the air outlet 201f, respectively. For example, the central axis of the guide housing 24f extends in the same direction as the airflow direction of the convection fan 23f. The guide housing 24f can guide air into the convection fan 23f and guide air out of the convection fan 23f. The first heating element 221f can be fixed to the upstream end of the guide housing 24f.

[0303] As further shown in Figure 53 , a conical guide portion 211f is protruding from the side of the cover body 21f facing the milk collection opening. An air outlet 201f is provided on the free end surface of the guide portion 211f, and an air inlet 202f is provided on the side of the cover body 21f facing away from the milk collection opening. When the dust cover 20f is installed on the breast pump 10f, air can enter the installation space 200f from the side of the cover body 21f facing away from the milk collection opening. The free end surface of the guide portion 211f directly faces the milk collection opening of the breast pump 10f, and hot air flowing out of the dust cover 20f can flow directly into the milk collection opening. There can be more than one air outlet 201f; for example, a plurality of air outlets 201f can be arranged in an array on the free end surface of the guide portion 211f.

[0304] It is understood that the air outlet 201f may be entirely or partially formed on the outer circumference of the guide portion 211f. For example, a portion of the air outlet 201f may be formed on the free end surface of the guide portion 211f, while another portion may be formed on the outer circumference of the guide portion 211f. In one embodiment, the air inlet 202f may also be formed on the outer circumference of the cover body 21f.

[0305] In one embodiment, when the dust cover 20f is mounted on the milk collection opening of the breast pump 10f, a gap is defined between the dust cover 20f and the milk collection opening. Thus, heated air exhausted from the air outlet 201f can be exhausted from at least one of the milk pouring port 100f of the breast pump 10f and the gap. For example, a portion of the hot air preheats the milk collection opening and is then exhausted from the gap between the dust cover 20f and the milk collection opening, removing dust and dirt from the gap in the process, thereby cleaning the milk collection opening of the breast pump 10f. Another portion of the hot air can enter the milk bowl of the breast pump 10f through the milk collection opening and then flow out from the milk pouring port 100f.

[0306] FIG54 shows a schematic structural diagram of a breast pumping device according to an embodiment of the present application, and FIG55 shows a cross-sectional view of a breast pump according to an embodiment of the present application.

[0307] Referring to Figures 54 and 55 , an embodiment of the present application provides a breast pump device, comprising a breast pump 10g and a dust cover 20g. The dust cover 20g can be used in conjunction with the breast pump 10g and is detachably connected to the breast pump 10g. The breast pump 10g has a milk collection opening 100g for covering the breast to collect milk. When the breast pump 10g is not in use, the dust cover 20g can cover the milk collection opening 100g of the breast pump 10g to protect it and prevent dust, bacteria, etc. from entering the breast pump 10g through the milk collection opening 100g. The dust cover 20g can also be used to disinfect and sterilize the breast pump 10g. When the breast pump 10g needs to be used, the dust cover 20g can be removed for normal use.

[0308] The breast pump 10g primarily includes a flange 110g and a milk bowl 12g. The milk bowl 12g is mounted on the flange 110g and is used to store breast milk. The flange 110g has a milk collection opening 100g, and the milk bowl 12g has a milk collection channel therein. The milk collection opening 100g communicates with the interior of the milk bowl through the milk collection channel. It is understood that a breast shield can be integrally or detachably mounted on the flange 110g, and the milk collection opening 100g is formed on the breast shield.

[0309] When using the breast pump, you need to first remove the dust cover 20g, then attach the milk collection opening 100g to the human body, operate the breast pump 10g, and use negative pressure to suck milk from the breast. The milk enters the milk bowl 12g through the milk collection opening 100g for storage.

[0310] It is understandable that the breast pump 10g can be a manual breast pump or an electric breast pump. In one embodiment, the breast pump 10g is an electric breast pump, which also includes a main unit that is used to generate negative pressure during operation to suck milk into the milk bowl 12g.

[0311] When the dust cover 20g is installed on the breast pump 10g, the dust cover 20g can cover the opening of the breast pump 10g, thereby preventing dust, bacteria, etc. from entering the breast pump and preventing the milk in the breast pump 10g from being contaminated and deteriorating. The dust cover 20g can also be used to disinfect the milk collection opening 100g of the breast pump 10g as needed to prevent bacteria from breeding in the milk collection channel and contaminating the milk in the breast pump 10g, thereby ensuring the health of the baby.

[0312] As shown in FIG55 , this embodiment provides a dust cover 20g, comprising a cover body 21g and a disinfection assembly 22g. The cover body 21g is configured to be mounted on a breast pump 10g to cover the milk collection opening 100g of the breast pump 10g. The cover body 21g defines an installation space 200g therein and has a light-emitting side facing the milk collection opening 100g. The disinfection assembly 22g is at least partially disposed within the installation space 200g and is configured to emit ultraviolet light through the light-emitting side to disinfect the milk collection opening 100g of the breast pump 10g.

[0313] Because the UV disinfection function is integrated into the dust cover 20g rather than the breast pump 10g, it does not increase the size of the breast pump 10g and fully utilizes the dust cover 20g for multiple purposes. The dust cover 20g not only protects against dust and bacteria, but also can be used to disinfect the breast pump 10g when not in use. When disinfection is required, simply activate the disinfection component 22g to irradiate the milk collection opening 100g with UV light.

[0314] FIG56 shows a schematic diagram of the structural decomposition of the breast pumping device according to an embodiment of the present application.

[0315] Further referring to FIG. 56 , in one embodiment, a conical protrusion 23g and a circle of receiving portions 24g surrounding the protrusion 23g are provided on the light-emitting side of the cover body 21g. The receiving portions 24g are used to partially embed the breast pump 10g when the protrusion 23g enters the milk collection opening 100g. Specifically, the periphery of the breast collection cover is embedded in the receiving portion 24g, and the protrusion 23g is accommodated within the breast collection cover. The conical protrusion 23g is constructed to gradually become smaller toward the free end. When the dust cover 20g is installed on the breast pump 10g, the conical protrusion 23g slides along the conical surface of the breast collection cover, guiding the dust cover 20g to cover the milk collection opening 100g of the breast pump 10g.

[0316] In one embodiment, the milk bowl 12g is at least partially made of a transparent material. For example, the side of the milk bowl 12g facing away from the flange 110g is transparent, allowing the user to view the internal structure of the breast pump 10g from the outside. This novel design allows the user to easily observe the amount of milk stored in the milk bowl 12g, thereby improving the practicality of the breast pump 10g. Specifically, the milk collection opening 100g is formed on the flange 110g, and the breast collection cover is made of an opaque material. For example, the entire flange 110g is made of an opaque material. The ultraviolet light emitted by the disinfection component 22g is irradiated to the opaque milk collection opening 100g, but not to the milk bowl 12g, thereby preventing the ultraviolet light from entering the human eye and causing harm to the user.

[0317] By designing the emission angle of the ultraviolet light of the disinfection component 22g, the ultraviolet light can be made to irradiate only the opaque milk collecting opening 100g. Exemplarily, the raised portion 23g includes an annular conical surface 232g, and the ultraviolet light emitted by the disinfection component 22g is emitted through the conical surface 232g and is obliquely emitted to the milk collecting opening 100g. In one embodiment, the conical surface 232g is configured to be light-transmissive as a whole, and the ultraviolet light emitted by the disinfection component 22g is emitted through the conical surface 232g; in another embodiment, the conical surface 232g is provided with a number of light-transmitting windows 234g, and the ultraviolet light emitted by the disinfection component 22g can only be emitted through the corresponding light-transmitting windows 234g, thereby limiting the emission path of the ultraviolet light to be emitted according to a preset path. It can be understood that the light-transmitting window 234g can be a through hole, or a light-transmitting material can be used there to provide a channel for ultraviolet light to pass through.

[0318] For example, in addition to the tapered surface 232g, the raised portion 23g may also include a first surface 231g and a second surface 233g, respectively connecting the two ends of the tapered surface 232. The first surface 231g and the second surface 233g are both annular in shape. The first surface 231g is located on the side close to the accommodating portion 24g, while the second surface 233g is located at the free end. When the dust cover 20g is placed on the breast pump 10g, the second surface 233g is close to the milk bowl, while the first surface 231g is close to the edge of the milk collection opening 100g. The first surface 231g and the second surface 233g may be tapered or flat.

[0319] Specifically, in this embodiment, the disinfection component 22g includes a lamp board 221g and a plurality of ultraviolet light sources 222g that are arranged in the installation space 200g and electrically connected. The lamp board 221g is fixed on the cover body 21g, and each ultraviolet light source 222g is arranged on the lamp board 221g at intervals along the circumference of the cover body 21g and faces the light output side.

[0320] For example, the milk collection opening 100g includes a breast receiving cavity and a nipple passage. The breast receiving cavity is closer to the human body than the nipple passage. The nipple passage connects the breast receiving cavity with the milk bowl 12g. The disinfection assembly 22g includes at least one ultraviolet light source 222g. The light emission direction of the ultraviolet light source 22g is configured to be inclined toward the center of the nipple passage. In this way, the ultraviolet light source 22g can illuminate the area of ​​the milk collection opening 100g corresponding to the nipple passage.

[0321] In one embodiment, as shown in Figures 56 and 57, the cover body 21g can include a rear cover 211g and a front cover 212g, the rear cover 211g and the front cover 212g cooperate to form an installation space 200g, the light board 221g is fixed to the rear cover 211g, the ultraviolet light source 222g is fixed to the light board 221g, and the protrusion 23g and the receiving portion 24g are formed on the front cover 212g. For example, the cover body 21g can be L-shaped, with the rear cover 211g and the front cover 212g both being L-shaped, so that the cover body 21g includes a main portion 21A for covering the breast collection opening 100g and a base portion 21B connected to the bottom of the main portion 21A. In this case, the protrusion 23g and the receiving portion 24g are formed on the main portion 21A. Exemplarily, the main portion 21A and the base portion 21B can be perpendicular to each other. When the main body portion 21A covers the milk collecting opening 100g of the breast pump 10g, the base portion 21B can support the breast pump 10g so that the breast pump 10g can stand stably on a flat surface.

[0322] In one embodiment, the light board 221g is annular or C-shaped, and the ultraviolet light sources 222g are spaced apart around the circumference of the light board 221g. Thus, the light emitted by each ultraviolet light source 222g converges to the corresponding area on the milk collecting opening 100g, disinfecting different parts and ensuring the disinfection effect.

[0323] In addition, to improve the light guiding effect, in one embodiment, the disinfection component 22g may include a plurality of light guide columns 223g, one end of each light guide column 223g faces the ultraviolet light source 222g, and the other end extends to the conical surface 232g and is tilted toward the center of the conical surface 232g to guide the light emitted by the ultraviolet light source 222g to be emitted through the conical surface 232g.

[0324] Since the free end of the light guide column 223g is tilted, the light emitted by the ultraviolet light source 222g will be directed toward the milk collection opening 100g of the breast pump 10g at a certain angle, ensuring that the ultraviolet light is irradiated to the milk collection opening 100g but not to the milk bowl 12g, thereby playing a certain light guiding role.

[0325] Correspondingly, when the light-transmitting window 234g is a through hole, the light-guiding column 223g passes through the light-transmitting window 234g and guides the ultraviolet light to a specific area on the breast pump 10g; when the light-transmitting window 234g is made of a translucent material rather than a through hole, the light-guiding column 223g can abut or align with the light-transmitting window 234g.

[0326] Furthermore, the disinfection assembly 22g may also include a light guide ring 224g, with each light guide column 223g connected to the light guide ring 224g. The side of the light guide ring 224g facing away from the light guide column 223g is attached to the side of the light board 221g provided with the ultraviolet light source 222g. For example, the light guide ring 224g and the light guide column 223g are integrally provided to facilitate assembly and improve assembly efficiency.

[0327] In addition, the disinfection component 22g can also include a light homogenizer 225g, which is attached to the inner surface of the raised portion 23g and directly opposite the tapered surface 232g. The light emitted by the ultraviolet light source 222g can be irradiated by the light homogenizer 225g. After being homogenized by the light homogenizer 225g, the light is more uniform, and the light homogenizer 225g can collect the light scattered in all directions and reuse it, thereby improving the light utilization rate. When the disinfection component 22g includes a light guide column 223g, the light homogenizer 225g can also be provided with a plurality of limiting holes 2250g, and the light guide column 223g can pass through the corresponding limiting holes 2250g. The limiting holes 2250g can play a certain limiting role on the light guide column 223g.

[0328] In one embodiment, the conical surface 232g may also be a reflective surface. Light emitted from the light-transmitting window 234g may be reflected by the conical surface 232g and further converged onto the breast pump 10g, thereby increasing light intensity.

[0329] In one embodiment, the dust cover 10g also includes a battery 25g disposed within the mounting space 200g. The battery 25g is electrically connected to the disinfection assembly 22g to power the disinfection assembly 22g. Thus, the dust cover 10g can disinfect the breast pump 20g without requiring an external power source, making it suitable for more portable use. It is understood that in other embodiments, the dust cover 10g may not include a battery, but may require an external power source to power the disinfection assembly 22g.

[0330] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
