[0060] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0061] In the related art, a breast pump generally includes a three-way connector, a horn cover, a milk bottle and a membrane assembly. The three-way connector has three ports, the first port is connected to the horn cover, the second port is connected to the milk bottle, and the third port is provided with a membrane assembly and connected to an air pump. The horn cover is used to cover the outside of the breast, the membrane assembly is used to change the air pressure in the three-way connector, and the horn cover and the membrane assembly are respectively arranged on the left and right sides of the upper part of the three-way connector, and the milk bottle is arranged at the lower end of the three-way connector.

[0062] However, in the related art, when the breast pump is in use, the user holds the three-way shell and presses the speaker cover onto the breast. In order to make the speaker cover fit tightly to the breast, it is usually necessary to hold the upper part of the three-way connector (i.e., the upper part of the breast pump). The upper part of the three-way connector is also provided with a membrane assembly, which is large in size, inconvenient to hold, and the user experience is poor.

[0063] In order to solve the above technical problems, the embodiments of the present disclosure provide a negative pressure generating component and a breast pump, wherein the negative pressure generating component includes a fastening member, a flexible member and a connecting valve. The flexible member is connected to the fastening member, and the flexible member includes a protruding portion protruding in a direction away from the fastening member, and a cavity is enclosed between the protruding portion and the fastening member, and the cavity is used to communicate with an air pressure source. Under the action of the air pressure source, the protruding portion moves up and down relative to the fastening member to suck milk into the space on the first side of the negative pressure generating component in the breast pump; the connecting valve is connected to the flexible member, and the connecting valve is used to allow milk to flow from the first side of the negative pressure generating component to the second side of the negative pressure generating component; wherein the first side is the side of the protruding portion away from the fastening member, and the first side and the second side are two opposite sides of the negative pressure generating component. The negative pressure generating assembly provided in this embodiment can be arranged between the container and the connecting piece of the breast pump, and the connecting piece is used to connect the horn cover and the container. Milk can enter the first side of the negative pressure generating assembly through the horn cover and the connecting piece, and flow into the second side of the negative pressure generating assembly through the connecting valve in the negative pressure generating assembly. In this way, the size of the breast pump close to the horn cover can be reduced, which is convenient for users to hold and carry. It can also be adapted to ordinary underwear on the market to facilitate users to put the breast pump into the underwear during milk pumping, thereby improving the user experience.

[0064] The present disclosure provides a negative pressure generating assembly, such as Figures 1 to 7 As shown, used in a breast pump, the negative pressure generating component includes a fastening member 1, a flexible member 2 and a connecting valve 3.

[0065] The flexible member 2 is connected to the fastening member 1, and the flexible member 2 includes a protrusion 21 protruding in a direction away from the fastening member 1. A cavity 22 is enclosed between the protrusion 21 and the fastening member 1. The cavity 22 is used to communicate with the air pressure source. The protrusion 21 moves up and down relative to the fastening member 1 under the action of the air pressure source to suck milk into the space on the first side of the negative pressure generating component in the breast pump.

[0066] The connecting valve 3 is connected to the flexible member 2, and is used to allow milk to flow from the first side of the negative pressure generating component into the second side of the negative pressure generating component; wherein the first side is the side of the protrusion 21 away from the fastening member 1, and the first side and the second side are opposite sides of the negative pressure component.

[0067] According to the embodiments of the present disclosure, it should be noted that:

[0068] like Figure 6 , Figure 7 As shown, the first side of the negative pressure generating component is the upper side of the negative pressure generating component, and the second side of the negative pressure generating component is the lower side of the negative pressure generating component. When the negative pressure generating component is connected to the breast pump, the first side can be the side where the connector 4 is located, and the second side can be the side where the container 6 is located. Among them, the connector 4 can be understood as the shell of the breast pump. When the user uses the breast pump, the connector 4 is usually grasped to cover the breast pump on the breast. It can be understood that the connector 4 includes two open ends, one of which is used to connect with the container 6, and the other open end is used to cover the breast or to be connected to the breast through other structures such as the adsorption member 5. It should be noted that the container 6 is a part of the breast pump, which is used to store the sucked milk.

[0069] The positions of the fastener 1 and the flexible member 2 in the breast pump can be understood as follows: the fastener 1 is arranged at the end of the negative pressure generating component close to the container 6, and the flexible member 2 is arranged at the end of the negative pressure generating component close to the breast. When the flexible member 2 is deformed toward the fastener 1, the pressure in the space formed by the negative pressure generating component and the breast can be reduced, thereby forming a negative pressure in the space, so as to simulate the suction force similar to that of a baby's mouth, and achieve the purpose of sucking milk from the breast.

[0070] The connecting valve 3 can be understood as a structure connecting the first side and the second side of the negative pressure generating component, that is, a valve structure connecting the connecting member 4 and the container 6. Milk can flow from the first side of the negative pressure generating component to the second side of the negative pressure generating component through the connecting valve 3. The milk can flow from the first side of the negative pressure generating component to the second side by its own gravity, or the milk can flow from the first side of the negative pressure generating component to the second side by the pressure difference between the first side and the second side.

[0071] The connecting valve 3 can be opened under the gravity of the milk. When the gravity of the milk on the first side of the negative pressure generating component reaches the opening pressure of the connecting valve 3, the connecting valve 3 is in an open state, so that the milk can flow to the second side of the negative pressure generating component. When the gravity of the milk on the first side of the negative pressure generating component does not reach the opening pressure of the connecting valve 3, the connecting valve 3 is in a closed state, or when the first side of the negative pressure generating component is in a negative pressure state, the connecting valve 3 is in a closed state. Specifically, the connecting valve 3 is a one-way valve structure, which can prevent the milk from flowing back to the first side of the negative pressure generating component.

[0072] In this embodiment, milk can flow from the first side of the negative pressure generating component into the second side of the negative pressure generating component through the connecting valve 3, which means that the negative pressure generating component provided in this embodiment can be arranged between the container 6 of the breast pump and the connecting member 4. Specifically, the fastening member 1 can be arranged close to the container 6, the flexible member 2 can be arranged away from the container 6, and the cavity 22 between the fastening member 1 and the flexible member 2 can be connected to the air pressure source.

[0073] In this embodiment, the connecting valve 3 can connect the container 6 (the second side of the negative pressure generating component) with the connecting member 4 (the first side of the negative pressure generating component), so that the milk sucked in the connecting member 4 can flow into the container 6, so that the negative pressure generating component can be arranged between the container 6 and the connecting member 4. Compared with the related art in which the membrane component is arranged on the upper part of the three-way connecting member, the size of the upper part of the connecting member 4 can be reduced ( Figure 7 The left-right dimension of the position where the middle suction piece 5 is located) thereby reducing the size of the upper part of the breast pump, making it easier for the user to hold and improving the user's breast pumping experience.

[0074] In the embodiment of the present application, the negative pressure generating component is an independent component, that is, it is independent of the connecting member 4, the container 6 and the adsorbent 5. This makes manufacturing easier on the one hand, and on the other hand, when a problem occurs with the negative pressure generating component, it can be easily replaced without complicated disassembly operations.

[0075] In one example, the negative pressure generating assembly can be disposed between the connector 4 and the container 6. There can be multiple positions of the negative pressure generating assembly, for example, the connector 4 has a first connecting end, the container 6 has a second connecting end for connecting to the first connecting end, and the first connecting end and the second connecting end have a partial overlap (for example, the first connecting end is sleeved outside the second connecting end), so that when the connector 4 and the container 6 are connected, the negative pressure generating assembly can be at least partially located in the overlapping portion. Of course, when the first connecting end and the second connecting end are connected without a partial overlap, the negative pressure generating assembly can be located between the first connecting end and the second connecting end, that is, the connector 4 can be connected to the container 6 through the negative pressure generating assembly, and specifically, the first connecting end of the connector 4 is connected to the second connecting end of the container 6 through the negative pressure generating assembly.

[0076] In one example, there are multiple ways to connect the negative pressure generating component with the container 6 and the connecting member 4. For example, when the connecting member 4 is directly connected to the container 6, the fastener 1 has a first abutting structure for abutting and cooperating with the milk inlet of the container 6 of the breast pump, and the flexible member 2 has a second abutting structure for abutting and cooperating with the connecting member 4 of the breast pump. The first abutting structure can be understood as a groove-like structure. When the fastener 1 is connected to the milk inlet of the container 6, the milk inlet of the container 6 abuts against the groove structure, or the first abutting structure can be understood as a plane structure. The milk inlet of the container 6 directly contacts the plane structure. The milk inlet can be understood as the opening of the container. The second abutting structure can be understood as a convex structure. When the flexible member 2 is connected to the connecting member 4, the convex structure abuts against the inner surface of the connecting member 4. Through the cooperation of the first abutting structure and the second abutting structure with the container 6 and the connecting member 4 respectively, the negative pressure generating component can be clamped and fixed in the breast pump, so that the connection of the negative pressure generating component in the breast pump is more stable. The fastener 1 may be a component of the negative pressure generating assembly close to the container 6, and there may be various positions of the fastener 1 and the container 6. For example, the fastener 1 may be directly installed in the opening of the container 6 through a snap connection, or may be installed outside the opening of the container 6, that is, the fastener 1 may cover the opening of the container 6. Of course, when the fastener 1 covers the outside of the container 6, a portion of the fastener 1 may extend into the container 6.

[0077] In one example, the fastener 1 can be a component made of rigid material, such as hard plastic (such as PPSU), hard silicone, etc., so that when the flexible part 2 changes its shape to adjust the pressure of the cavity 22, the fastener 1 is not easily deformed as the pressure of the cavity 22 changes, thereby facilitating the formation of negative pressure inside the connector 4.

[0078] In one example, the flexible member 2 and the fastening member 1 can be connected in a variety of ways. For example, the flexible member 2 and the fastening member 1 can be connected by fitting, or the flexible member 2 and the fastening member 1 can be connected by a mutually adapted snap-fit ​​structure, or the flexible member 2 and the fastening member 1 can be connected by a mutually adapted plug-in structure.

[0079] In one embodiment, (such as Figures 1 to 4 (As shown in the figure), the edge of the fastening member 1 is provided with a connecting portion 15, and the edge of the flexible member 2 is provided with a matching portion 25 that matches the shape of the connecting portion 15. There are many ways to match and connect the connecting portion 15 and the matching portion 25. For example, the connecting portion 15 includes a slot arranged around the edge of the fastening member 1, and the matching portion 25 includes a protrusion that is engaged with the slot.

[0080] The clamping groove arranged around the edge of the fastening member 1 can be understood as an annular clamping groove arranged on the periphery of the fastening member 1, and the matching portion 25 includes an annular protrusion engaged with the clamping groove.

[0081] In one embodiment, the connecting portion 15 includes a protrusion disposed around the edge of the fastening member 1 , and the matching portion 25 includes a slot engaged with the protrusion.

[0082] The protrusion arranged around the edge of the fastening member 1 can be understood as an annular protrusion arranged on the periphery of the fastening member 1, and the matching portion 25 includes an annular groove engaged with the groove.

[0083] In the above-mentioned embodiments, the connecting portion 15 and the matching portion 25 are connected by means of the protrusion and the slot, thereby improving the airtightness of the connection between the flexible member 2 and the fastening member 1 .

[0084] In one embodiment, the connecting portion 15 is in abutment connection with the matching portion 25. The abutment connection can be understood as the connecting portion 15 being pressed against the matching portion 25, thereby achieving the connection between the fastening member 1 and the flexible member 2.

[0085] By providing the connection portion 15 and the matching portion 25 in abutting connection, the airtightness of the cavity 22 surrounded by the fastening member 1 and the flexible member 2 can be improved.

[0086] In one example, the fastener 1 has two side surfaces facing away from each other, wherein one side surface ( Figure 4 The lower surface of the flexible member 2 is connected to the other side surface ( Figure 4 The flexible member 2 is provided with a protruding portion 21 protruding in a direction away from the fastening member 1, and a cavity 22 is formed between the inner surface of the protruding portion 21 and the other side surface of the fastening member 1.

[0087] In one example, the flexible member 2 is an integrally formed flexible silicone member, for example, the flexible member 2 is made of a flexible material such as a deformable soft rubber, a flexible silicone, etc. The protrusion 21 of the flexible member 2 can move up and down relative to the fastening member 1 through its own flexibility under the action of an air pressure source (such as an air pump), thereby forming a negative pressure in the connecting member 4, and then sucking the milk into the breast pump.

[0088] In another example, the flexible member 2 may be formed by connecting a plurality of flexible sub-components through a common connection method.

[0089] In one example, the connecting valve 3 is an integrally formed flexible silicone member, for example, the connecting valve 3 is made of flexible materials such as soft glue, flexible silicone, etc. The connecting valve 3 and the flexible member 2 can be two separate components, which can be connected by a common connection method.

[0090] In one example, the flexible member 2 and the connecting valve 3 are an integrally formed flexible silicone member. The integrally formed flexible member 2 and the connecting valve 3 can avoid the problem of air leakage at the connection of multiple components, and the integrally formed structure is simple and easy to clean.

[0091] In one example, the connecting valve 3 adopts a one-way valve structure to prevent milk from flowing back. In addition, the connecting valve 3 can be arranged outside the cavity 22. The connecting valve 3 is arranged outside the cavity 22, which can be understood as the cavity 22 and the connecting valve 3 can be arranged in a horizontal direction (such as Figure 6 The two devices are spaced apart in the left and right directions so that their work does not affect each other.

[0092] In one embodiment, Figure 4 , Figure 6 As shown, the fastener 1 includes a main body 11 and a first tubular body 12, one end of the first tubular body 12 is connected to the main body 11, and a protrusion 21 is covered on the other end of the first tubular body 12, and the protrusion 21, the first tubular body 12 and the part of the main body 11 surrounded by the first tubular body 12 together form a cavity 22.

[0093] According to the embodiments of the present disclosure, it should be noted that:

[0094] The body 11 can be understood as a plate-like structure at the bottom of the fastener 1. Figure 6 The body 11 may have an upper surface and a lower surface, and an annular cylindrical body (i.e., the first cylindrical body 12) may protrude from the upper surface of the body 11. When the fastener 1 and the flexible member 2 are matched, the first cylindrical body 12 is inserted into the inside of the protruding portion 21, that is, the outer surface of the first cylindrical body 12 may be closely connected with the inner surface of the protruding portion 21, so that the protruding portion 21 can cover the upper opening of the first cylindrical body 12.

[0095] According to the embodiment of the present disclosure, by covering the protrusion 21 on the first cylindrical body 12, the contact surface between the protrusion 21 and the fastening member 1 is increased to improve the tightness of the connection between the flexible member 2 and the fastening member 1, thereby improving the airtightness of the cavity 22.

[0096] In one embodiment, Figure 4 , Figure 6 As shown, the portion of the body 11 surrounded by the first cylindrical body 12 is protruded in a direction away from the protruding portion 21 .

[0097] It can be understood that the partial area of ​​the main body 11 located in the first cylindrical body 12 is protruded toward the second side close to the negative pressure generating component, which can increase the internal space of the cavity 22 to provide sufficient ups and downs space for the protrusion 21 to make ups and downs motion relative to the fastener 1.

[0098] In one embodiment, Figure 4 , Figure 6 As shown, the first cylindrical body 12 is provided with a connecting portion 121 for connecting the air pressure source with the cavity 22 , the connecting portion 121 is connected to the body 11 , and the connecting portion 121 extends in a direction away from the first cylindrical body 12 until it protrudes from the body 11 .

[0099] In this embodiment, the connecting portion 121 can be arranged on the outer circumference of the first tubular body 12 and connected to the body 11. That is, the connecting portion 121 can be protruded from the outer circumference of the first tubular body 12, and the connecting portion 121 protrudes from the edge of the body 11. Alternatively, the connecting portion 121 can be understood as a tubular structure connected to the body 11 at the side, one end of which is connected to the cavity 22, and the other end extends to the outside of the edge of the body 11 to connect the cavity 22 with the air pressure source. The connecting member 4 can have a first notch, and the connecting portion 121 can extend out of the first notch, that is, the connecting portion 121 can protrude out of the entire breast pump, so as to facilitate connection with the air pressure source, so that the air pressure source controls the air pressure in the cavity 22 through the connecting portion 121.

[0100] In addition, in this embodiment, since the negative pressure generating component is located between the connecting member 4 and the container 6, the connecting portion 121 is also roughly located between the connecting member 4 and the container 6. Compared with the air pump connected to the upper port of the three-way shell in the related art, the size of the upper part of the breast pump can be reduced, making it more convenient for users to hold and use.

[0101] In one embodiment, Figure 4 , Figure 5 As shown, the body 11 is provided with at least one communication groove 111, and each of the at least one communication groove 111 is used to connect the external environment of the breast pump with the internal space of the breast pump located on the second side of the negative pressure generating component.

[0102] That is to say, a connecting groove 111 is provided on the main body 11, and the connecting groove 111 can be exposed at the first notch on the connecting member 4. When the main body 11 covers and abuts against the milk inlet of the container 6, the internal space of the container 6 can be connected with the external environment of the breast pump through the connecting groove 111 exposed at the first notch. The connecting groove 111 can have various shapes, such as a second notch recessed on the end face of the main body 11, or a hole-like structure penetrating the main body 11. The positions of the multiple connecting grooves 111 on the main body 11 can be various, such as being evenly arranged on the main body 11, or multiple connecting grooves 111 being adjacently arranged on the main body 11. In one example, the connecting groove 111 is located on the side of the connecting portion 121 away from the protruding portion 21, which can be understood as: the connecting groove 111 is located on the main body 11 close to the connecting portion 121, and the connecting groove 111 is located on the end face of the main body 11 facing the second side of the negative pressure generating component (towards the container 6), for example Figure 4 , Figure 5 The two notches below the middle connecting portion 121 are the connecting grooves 111 .

[0103] During the process of breast pumping, as the milk enters the container 6, the air in the container 6 needs to be discharged to ensure the stability of the pressure in the container 6. By providing the connecting groove 111, the pressure in the internal space of the container 6 can be stabilized, and negative pressure will not be generated in the container 6, so that the breast pumping work can proceed smoothly.

[0104] In one embodiment, Figures 1 to 6 As shown, the communication valve 3 and the protrusion 21 are arranged at intervals along a direction parallel to the fastening member 1, and the fastening member 1 is provided with a through hole 13 for penetrating the communication valve 3.

[0105] According to the embodiments of the present disclosure, it should be noted that:

[0106] The direction parallel to the fastening member 1 may be a horizontal direction, that is, Figure 6 The left and right direction in .

[0107] In this embodiment, the connecting valve 3 is arranged outside the protruding portion 21 , and the through hole 13 can be arranged at a position in the fastening member 1 corresponding to the connecting valve 3 .

[0108] When the flexible member 2 is connected with the fastening member 1, the connecting valve 3 can be inserted into the through hole 13 of the fastening member 1. The extension length of the connecting valve 3 toward the fastening member 1 can be adjusted, for example, the connecting valve 3 extends to the inside of the container 6, or the connecting valve 3 extends to the opening of the container 6.

[0109] According to the embodiment of the present disclosure, by providing a through hole 13 at a position of the fastening member 1 relative to the connecting valve 3 , milk can pass through the fastening member 1 into the container 6 .

[0110] In one embodiment, Figures 1 to 6 As shown, the flexible member 2 further comprises a base 23 connected to the fastening member 1 , the protrusion 21 is protrudingly disposed on a first surface 231 of the base 23 facing away from the fastening member 1 , and the inlet end of the connecting valve 3 is located in the first surface 231 .

[0111] According to the embodiments of the present disclosure, it should be noted that:

[0112] The substrate 23 may be a substantially plate-like structure, such as Figure 6 As shown, the first surface 231 may be the upper surface of the base 23, the protrusion 21 may be arranged to protrude upward from the first surface 231 of the base 23, the connecting valve 3 may extend downward from the base 23, and the inlet end of the connecting valve 3 is connected to the first surface 231 of the base 23. It can be understood that the connecting valve 3 has an inlet end and an outlet end, and the milk enters the connecting valve 3 from the inlet end and flows out of the connecting valve 3 from the outlet end.

[0113] The first surface 231 may be a plane or an inclined surface with the inlet end of the connecting valve 3 as the lowest point, so that the milk can enter the connecting valve 3 as much as possible. In one example, the first surface 231 is smoothly connected to the inlet end of the connecting valve 3, so as to facilitate the milk to flow from the first surface 231 of the base 23 to the connecting valve 3, and avoid the milk from accumulating in the connecting member 4, resulting in milk waste.

[0114] According to the embodiment of the present disclosure, by setting the inlet end of the connecting valve 3 to be connected to the first surface 231 of the base 23, after the breast secretes milk, the milk will flow to the connecting valve 3 through the first surface 231, thereby avoiding milk waste.

[0115] In one embodiment, the communication valve 3 comprises a conical valve body with a communication passage inside, and the conical valve body can open the communication passage under the action of the gravity of the milk.

[0116] According to the embodiments of the present disclosure, it should be noted that:

[0117] In this embodiment, the connecting valve 3 may be a deformable valve made of a flexible material, which can be opened under the action of the gravity of the milk.

[0118] One end of the conical valve body connected to the flexible member 2 is the inlet end, and the end extending toward the container 6 is the outlet end. The diameter from the inlet end to the outlet end gradually decreases to a closed state. When milk does not flow toward the conical valve body, the conical valve body is in a closed state. When milk flows toward the conical valve body, the conical valve body is in an open state.

[0119] In one embodiment, Figures 4 to 6 As shown, the fastener 1 is also provided with a second cylindrical body 14, the inner cavity of the second cylindrical body 14 constitutes a through hole 13; the side of the flexible member 2 away from the protrusion 21 is provided with a groove 24 for snap-fitting connection with the other end of the second cylindrical body 14, and the connecting valve 3 passes through the second cylindrical body 14.

[0120] According to the embodiments of the present disclosure, it should be noted that:

[0121] The second cylindrical body 14 can be arranged on the body 11, and the second cylindrical body 14 extends toward the direction of the protruding portion 21, and the inner cavity of the second cylindrical body 14 is the through hole 13. The side of the flexible member 2 away from the protruding portion 21 has a recessed groove 24, and when the connecting valve 3 is inserted into the through hole 13, the second cylindrical body 14 is inserted into the groove 24, and the connecting valve 3 is inserted at one end of the through hole 13 ( Figure 6 The lower end of the middle connecting valve 3 can be located in the through hole 13, or can extend outside the through hole 13 (that is, penetrate the through hole 13).

[0122] According to the embodiment of the present disclosure, the second cylindrical body 14 and the groove 24 are provided to fit each other, so as to improve the sealing degree of the connection between the fastening member 1 and the flexible member 2 and avoid affecting the air pressure in the cavity 22 .

[0123] like Figure 7 As shown, the present disclosure provides a breast pump, which includes a connector 4, a container 6 and a negative pressure generating assembly in any of the above embodiments; one end of the connector 4 is connected to the container 6, and the other end of the connector 4 has a milk inlet; the flexible member 2 in the negative pressure generating assembly abuts against the connector 4, and the negative pressure generating assembly is used to form a negative pressure for sucking milk in the connector 4 through the undulating movement of the protrusion 21 in the flexible member 2, and the connecting valve 3 in the flexible member 2 is used to allow milk to flow from the connector 4 into the container 6.

[0124] According to the embodiments of the present disclosure, it should be noted that:

[0125] There are many ways to connect the connector 4 to the container 6, such as snap-fit ​​connection, threaded connection, etc. The other end of the connector 4 can be directly covered on the breast, or connected to the breast through other structures, such as connected to the breast through the adsorbent 5, that is, one end of the adsorbent 5 is covered on the breast, and the other end is connected to the milk inlet. There are many ways to connect the milk inlet and the adsorbent 5, such as snap-fit ​​connection, threaded connection, etc. The adsorbent 5 can be understood as a structure for covering the breast, which can take a variety of shapes. The container 6 is a structure for loading milk, which can be a bottle-shaped or bagged structure. The connector 4 can be understood as a structure for connecting the container 6 and the adsorbent 5. For example, the connector 4 can have two ports, one port is connected to the adsorbent 5, and the other port is connected to the container 6. Alternatively, the connector 4 includes a structure for covering the breast.

[0126] The negative pressure generating assembly is disposed between the connecting member 4 and the opening of the container 6. The milk flows to the upper side of the flexible member 2 of the negative pressure generating assembly through the adsorbent member 5 and the connecting member 4 in sequence. The milk on the flexible member 2 flows to the container 6 through the connecting valve 3 to complete the collection of the milk. The structure and description of the negative pressure generating assembly can refer to the above embodiment and will not be repeated here.

[0127] When using the breast pump, the adsorption member 5 is placed on the breast, and the air pressure source is turned on to adjust the air pressure in the cavity 22 of the negative pressure generating assembly, so that the protrusion 21 moves up and down with the change of air pressure, and during the ups and downs of the protrusion 21, negative pressure can be alternately formed in the connecting member 4, thereby simulating an environment similar to the sucking of a baby's mouth, and promoting the secretion of milk from the breast. The milk secreted by the breast will flow to the flexible member 2 through the connecting member 4 in turn, and flow into the container 6 through the connecting valve 3 to complete the collection of the milk.

[0128] According to the embodiments of the present disclosure, since the negative pressure generating assembly can be disposed between the container 6 and the connector 4, the width of the breast pump close to the breast is reduced, making it easier to hold and improving the user experience.
