[0089] The following describes exemplary embodiments of the present disclosure with reference to the accompanying drawings. Various details of the embodiments of the present disclosure are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted below.

[0090] In the related art, a breast pump is connected to a main unit, and an air pump is provided in the main unit. The air pump can be used to create a negative pressure in the breast pump, so that the breast pump can suck milk. However, the air pump usually has an intake pipe and an outlet pipe. Since both the intake pipe and the outlet pipe protrude from the air pump, the volume of the air pump is relatively large, and thus the volume of the main unit connected to the breast pump is relatively large, which makes it inconvenient for users to operate and carry.

[0091] To solve the above technical problems, the present disclosure provides a driving component, a breast pump main body, and a breast pumping device. The driving component at least includes an air pump. The air pump includes an air pump body, an air inlet pipe, and an air outlet hole. The air inlet pipe protrudes from the air pump body, and the air outlet hole is recessed in the air pump body. Among them, the air pump body is used to provide power so that air flows into the air pump body through the air inlet pipe and is discharged from the air pump body through the air outlet hole. By adopting the arrangement of using the air outlet hole recessed in the air pump body for exhaust, the volume of the air pump can be reduced, and further the volumes of the driving component and the breast pump main body can be reduced, which is convenient for carrying.

[0092] As Figures 1 to 9 shown, an embodiment of the present disclosure provides a driving component, which at least includes an air pump. The air pump includes an air pump body 1, an air inlet pipe 2, and an air outlet hole 3. The air inlet pipe 2 protrudes from the air pump body 1, and the air outlet hole 3 is recessed in the air pump body 1. Among them, the air pump body 1 is used to provide power so that air flows into the air pump body 1 through the air inlet pipe 2 and is discharged from the air pump body 1 through the air outlet hole 3.

[0093] The type of the air pump can include various types, such as a piston air pump, a diaphragm air pump, etc. The air pump body 1 can be understood as a structure for sucking and discharging gas, and it can transport gas through the movement of an internal mechanical structure. For example, when the air pump adopts a piston air pump, the air pump body 1 transports gas through the reciprocating movement of a piston cylinder. When the air pump adopts a diaphragm air pump, the air pump body 1 transports gas through the reciprocating movement of a diaphragm.

[0094] The air inlet pipe 2 is a structure for inputting gas into the air pump body 1. It can be an integral part integrally formed with the air pump body 1 or two independent parts detachably connected to the air pump body 1. The air inlet pipe 2 protrudes from the air pump body 1, which can be understood as one end of the air inlet pipe 2 is connected to the air pump body 1 and the other end extends to the outside of the air pump body 1. The air inlet pipe 2 protruding from the air pump body 1 is convenient for connecting to structures such as a solenoid valve assembly and a pipeline in the breast pump main body.

[0095] The air outlet hole 3 is a structure for discharging gas from the air pump body 1. It can be any hole-shaped structure communicating the inside of the air pump body 1 with the outside of the air pump body 1. The air outlet hole 3 is recessed in the air pump body 1, which can be understood as there is a through hole on the air pump body 1 communicating the inside and the outside of the air pump body 1, but the exposed opening of the through hole does not protrude at least from the outer surface of the air pump body 1. The air outlet hole 3 recessed in the air pump body 1 can reduce the volume of the air pump body 1.

[0096] The opening and closing of the air inlet pipe 2 and the air outlet hole 3 can be determined by relevant valves in the air pump body 1. That is to say, when the air pump body 1 works, the ventilation states of the air inlet pipe 2 and the air outlet hole 3 with the air cavity 123 in the air pump body 1 can be controlled. For example, when the air pump body 1 sucks air, the air cavity 123 inside the air pump body 1 is not connected to the air outlet hole 3, and the air inlet pipe 2 is connected to the air cavity 123, so that gas can enter the air cavity 123 of the air pump body 1 from the air inlet pipe 2 (this air cavity 123 is the cavity that accommodates air when the air pump body 1 sucks air). When the air pump body 1 compresses the gas inside the air cavity 123, that is, when the air pump body 1 discharges air, the air cavity 123 is not connected to the air inlet pipe 2, but is connected to the air outlet hole 3, so that the gas in the air pump body 1 can be discharged from the air outlet hole 3. That is to say, when the air pump body 1 works, the air intake state of the air inlet pipe 2 and the air exhaust state of the air outlet hole 3 alternate. When gas flows through the air inlet pipe 2, no gas flows through the air outlet hole 3. When no gas flows through the air inlet pipe 2, gas flows through the air outlet hole 3.

[0097] The air inlet pipe 2 and the air outlet hole 3 can be located at the same height as shown in Figure 2 , or can be located at different heights, and can be adjusted as needed.

[0098] When using the driving assembly, the driving assembly is connected to the breast pump 9. As the air pump body 1 works, the air pump body 1 extracts the gas in the breast pump 9 covering the breast through the air inlet pipe 2, so that a negative pressure is formed in the breast pump 9, thereby promoting the breast to secrete milk and achieving the purpose of using the breast pump 9 to suck milk. At the same time, the gas sucked by the air pump body 1 will be discharged through the air outlet hole 3 to avoid excessive pressure on the air pump body 1.

[0099] According to an embodiment of the present disclosure, integrating the air pump body 1, the air inlet pipe 2 and the air outlet hole 3 on the air pump can improve the airtightness of the air pump body 1. The air inlet pipe 2 protrudes from the air pump body 1 to facilitate connection with other structures such as solenoid valve assemblies and pipelines. The air outlet hole 3 is recessed in the air pump body 1. Compared with the exhaust pipe protruding in the related art, the volume of the air pump can be reduced, and thus the volumes of the driving assembly and the breast pump main body can be reduced, which is convenient for carrying.

[0100] In one embodiment, the area of the second cross-section of the air outlet hole 3 is 5 to 10 times the area of the first cross-section of the air inlet pipe 2. Exemplarily, the area of the second cross-section can be 5 times, 6 times, 8 times, 9 times, 10 times, etc. of the first cross-section. Among them, the first cross-section is the cross-section perpendicular to the axis of the air inlet pipe 2 in the air inlet pipe 2, and the second cross-section is the cross-section perpendicular to the axis of the air outlet hole 3 in the air outlet hole 3.

[0101] It can be understood that the diameter of the air inlet pipe 2 is smaller than the diameter of the air outlet hole 3.

[0102] According to an embodiment of the present disclosure, the air outlet 3 is larger than the air inlet, that is, the volume of the cavity in the air outlet is larger, which can improve the efficiency of the air outlet 3 discharging air, thereby reducing the noise generated due to the small cavity of the air outlet during the exhaust of the air pump.

[0103] In some embodiments, as Figure 1 , Figure 2 shown, a sound-absorbing cotton 31 is provided in the air outlet 3. To reduce the noise of the air pump vibration and the noise of the air discharged from the air outlet 3. The specific setting method of the sound-absorbing cotton 31 can be adhered to the side wall of the air outlet 3 or the sound-absorbing cotton 31 is squeezed against the side wall of the air outlet 3. Of course, other conventional fixing methods can also be used, which are not specifically limited herein.

[0104] In one embodiment, as Figure 1 , Figure 2 , Figure 9 shown, the air pump body 1 includes a cover plate 11, a pump assembly 13, and a valve plate 12 disposed between the cover plate 11 and the pump assembly 13. The valve plate 12 has an air chamber 123; the pump assembly 13 is used to change the pressure of the air chamber 123 to achieve the air pumping and exhausting of the air pump body 1. In addition, the intake pipe 2 protrudes from the cover plate 11, and the air outlet 3 is recessed in the cover plate 11, and both the intake pipe 2 and the air outlet 3 are communicated with the air chamber 123, that is, the intake pipe 2 and the air outlet 3 are communicated through the air chamber 123. When in use, the air flow enters the air chamber 123 from the intake pipe 2, and the air flow enters the air outlet 3 from the air chamber 123. In addition, to control the air pump body 1 to pass through the intake pipe 2 and the air outlet 3 respectively during air pumping and exhausting, two one-way valves (the first one-way valve 121 and the second one-way valve 122) are provided to control the flow direction of the air flow. Among them, the first one-way valve 121 is disposed between the air chamber 123 and the intake pipe 2 for allowing the air flow to enter the air chamber 123 from the intake pipe 2, and the second one-way valve 122 is disposed between the air chamber 123 and the air outlet 3 for allowing the air flow to enter the air outlet 3 from the air chamber 123.

[0105] The cover plate 11 can be understood as Figure 2 the structure covering the valve plate 12.

[0106] The valve plate 12 is disposed between the cover plate 11 and the pump assembly 13. The valve plate 12 has an air chamber 123. The pump assembly 13 has a rubber membrane 135. The rubber membrane 135 seals the opening of the air chamber 123, and during the up and down movement of the rubber membrane 135, the pressure of the air chamber 123 can be changed. It can be understood that Figure 2 only two parts of the air chamber 123 are shown. When the rubber membrane 135 moves downward, the air chamber 123 also includes a cavity part between the upper part of the rubber membrane 135 and the valve plate 12, and this cavity part can communicate with the two parts indicated by the reference numeral 123. In the embodiment as Figure 2 shown, an air chamber 123 is formed between the valve plate 12 and the rubber membrane 135. ToFigure 2 The placement direction of the air pump is the reference direction. When the rubber membrane 135 moves downward, the pressure in the air cavity 123 decreases, and when the rubber membrane 135 moves upward, the pressure in the air cavity 123 increases.

[0107] In one embodiment, two opposite end surfaces of the valve plate 12 are respectively provided with a first one-way valve 121 and a second one-way valve 122 .

[0108] It can be understood that the valve plate 12 is provided with a first one-way valve 121 and a second one-way valve 122 at intervals. The two ends of the first one-way valve 121 are connected to the air inlet pipe 2 and the air cavity 123, respectively. The conduction direction of the first one-way valve 121 is: from the air inlet pipe 2 to the air cavity 123. The first one-way valve 121 is used to open when the pressure in the air cavity 123 decreases, and the gas can enter the air cavity 123 through the air inlet pipe 2. The two ends of the second one-way valve 122 are connected to the air outlet 3 and the air cavity 123, respectively. The conduction direction of the second one-way valve 122 is: from the air cavity 123 to the air outlet 3. The second one-way valve 122 is used to discharge the high-pressure gas in the cavity 123 through the air outlet 3 when the pressure in the air cavity 123 increases.

[0109] According to the embodiment of the present disclosure, the ventilation state between the air inlet pipe 2 and the air outlet hole 3 can be controlled by providing a one-way valve structure.

[0110] The pump assembly 13 is the power part of the air pump, which can adjust the pressure in the air cavity 123. In some embodiments, Figure 2 As shown, the pump assembly 13 includes a motor 131, a cam 132, a crankshaft 133, an air pump housing 134, and a rubber membrane 135. The cam 132 and the crankshaft 133 are arranged in the air pump housing 134, the crankshaft 133 is connected to the rotating shaft of the motor 131 through the cam 132, the rubber membrane 135 is arranged at one end of the crankshaft 133 away from the cam 132, and the rubber membrane 135 is sandwiched between the air pump housing 134 and the valve plate 12. The cam 132 is driven to rotate by the rotation of the rotating shaft of the motor 131, the cam 132 drives the crankshaft 133 to do reciprocating motion (i.e., undulating motion), and the crankshaft 133 drives the rubber membrane 135 to do reciprocating motion (i.e., undulating motion) synchronously, thereby adjusting the air pressure in the air cavity 123, so that the air inlet pipe 2 can inhale air or the air outlet hole 3 can exhaust air.

[0111] There are many ways to connect the cover plate 11, the valve plate 12 and the pump assembly 13, such as snap connection, fitting connection, or connecting the three by other structures (such as screws).

[0112] According to the embodiment of the present disclosure, the cover plate 11, valve plate 12 and pump assembly 13 are provided independently of each other, so as to facilitate the later maintenance of the air pump body 1. The valve plate 12 is provided with a first one-way valve 121 and a second one-way valve 122, which can control the ventilation state of the air cavity 123 and the air inlet pipe 2 and the air outlet 3.

[0113] In one embodiment, the intake pipe 2 protrudes from the first side surface of the cover plate 11, and the air outlet 3 is recessed into the cover plate 11 from the second side surface of the cover plate 11.

[0114] The first side surface and the second side surface of the cover plate 11 are different side surfaces on the cover plate 11. Exemplarily, the first side surface and the second side surface of the cover plate 11 can be two adjacent side surfaces on the cover plate 11, thereby reducing the mutual influence between the intake air flow and the exhaust air flow, and thus reducing vibration and noise. At the same time, arranging the intake pipe 2 and the air outlet 3 on the cover plate 11 can optimize the pipeline structure in the pump assembly 13.

[0115] In one embodiment, as Figures 5 to 8 shown, the drive assembly further includes a solenoid valve assembly, which can be understood as a structure arranged between the breast pump 9 and the air pump body 1.

[0116] The solenoid valve assembly includes a connector 4, a first solenoid valve 5 and a second solenoid valve 6, and the first solenoid valve 5 and the second solenoid valve 6 are connected to the connector 4. The connector 4 includes an air outlet passage 41, a first intake passage 42 and a second intake passage 43. Among them, the air outlet passage 41 is communicated with the intake pipe 2, and at least one of the first intake passage 42 and the second intake passage 43 is used for communicating with the breast pump 9; so that the breast pump 9 is communicated with the air cavity 123 in the air pump body 1, and the breast pumping action of the breast pump 9 is realized by the air extraction and exhaust of the air pump body 1. In addition, the first solenoid valve 5 is used to control the on-off between the air outlet passage 41 and the first intake passage 42, and the second solenoid valve 6 is used to control the on-off between the air outlet passage 41 and the second intake passage 43, so as to cooperate with the connection situation of the first intake passage 42 and the second intake passage 43 with the breast pump 9. Exemplarily, when the first intake passage 42 is communicated with the breast pump 9, the first solenoid valve 5 controls the air outlet passage 41 to be conducted with the first intake passage 42 to provide the negative pressure required for the breast pump 9 to pump milk; when the second intake passage 43 is communicated with the breast pump 9, the second solenoid valve 6 controls the air outlet passage 41 to be conducted with the second intake passage 43 to provide the negative pressure required for the breast pump 9 to pump milk.

[0117] In the embodiment of the present application, the connector 4 includes an air outlet passage 41, and the air outlet passage 41 is simultaneously communicated with the first intake passage 42 and the second intake passage 43. At this time, when the solenoid valve assembly is communicated with the air pump, only one pipeline is required to communicate the air outlet passage 41 with the intake pipe 2.

[0118] In the related art, when two solenoid valves are provided in a breast pump drive assembly, each solenoid valve respectively corresponds to an air outlet passage and an air inlet passage. Correspondingly, the air pump needs to be provided with intake pipes corresponding to the two air outlet passages respectively to form a connection between the air pump and the solenoid valve assembly. In the solution disclosed in the present application, the number of the air outlet passages 41 is only one, thereby reducing the volume of the solenoid valve assembly. At the same time, only one intake pipe 2 is required to realize the connection between the air pump and the solenoid valve assembly, reducing the volume of the drive assembly. At the same time, the relatively small number of air outlet passages 41 can reduce the vibration and noise caused by the air flow during air outlet.

[0119] The air outlet passage 41, the first air inlet passage 42 and the second air inlet passage 43 can be all arranged on the same side of the connecting member 4, or can be arranged on different sides. The distance from the air outlet passage 41 to the first air inlet passage 42 (i.e., the path that the gas passes through) and the distance between the air outlet passage 41 and the second air inlet passage 43 can be the same or different.

[0120] In one embodiment, the first air inlet passage 42 and the second air inlet passage 43 are symmetrically arranged on both sides of the air outlet passage 41.

[0121] With such an arrangement, the path that the air flows through the first air inlet passage 42 and the second air inlet passage 43 in the connecting member 4 can be made equal. When the drive assembly is connected to two breast pumps 9, the negative pressure generated by the two breast pumps 9 for sucking milk can be made the same, improving the user experience.

[0122] The first solenoid valve 5 can be understood as a structure provided between the air outlet passage 41 and the first air inlet passage 42 and used to control the on-off state between the air outlet passage 41 and the first air inlet passage 42. The second solenoid valve 6 can be understood as a structure provided between the air outlet passage 41 and the second air inlet passage 43 and used to control the on-off state between the air outlet passage 41 and the second air inlet passage 43.

[0123] The switch states of the first solenoid valve 5 and the second solenoid valve 6 can be adjusted. For example, the switch states of the first solenoid valve 5 and the second solenoid valve 6 are set to be the same, that is, when the first solenoid valve 5 is opened, the second solenoid valve 6 is also opened. Or the switch states of the first solenoid valve 5 and the second solenoid valve 6 are set to be different, that is, when the first solenoid valve 5 is opened, the second solenoid valve 6 is closed, which can also be understood as the first solenoid valve 5 and the second solenoid valve 6 are alternately opened.

[0124] The connection relationship between the connecting member 4 and the first solenoid valve 5 and the second solenoid valve 6 can be in various forms. For example, it can be snap-connected, plugged, or fixed by other structures (such as screws).

[0125] According to an embodiment of the present disclosure, by providing an air outlet passage 41 communicated with the intake pipe 2, a first intake passage 42 and a second intake passage 43 communicated with the breast pump 9, the air passing through the first solenoid valve 5 and the second solenoid valve 6 can be discharged to the intake pipe 2 of the air pump through the same air outlet passage 41, that is, the air outlet passages of the two solenoid valves are combined into one, reducing the number of air connection ports of the connecting member 4. At the same time, the number of pipes connected to the air connection ports can be reduced, reducing the occupied volume. At the same time, by providing the first solenoid valve 5 and the second solenoid valve 6, the on / off of the first intake passage 42 and the second intake passage 43 can be controlled respectively, enabling the user to suck milk from one breast alone or from both breasts simultaneously, meeting different needs of the user.

[0126] In one embodiment, the air outlet passage 41, the first intake passage 42, and the second intake passage 43 are located on the side of the solenoid valve assembly away from the side of the air pump body 1 where the intake pipe 2 is provided.

[0127] It can be understood that, as Figure 6 shown, the first solenoid valve 5 and the second solenoid valve 6 are located on the first side of the connecting member 4, the air outlet passage 41, the first intake passage 42, and the second intake passage 43 are provided on the second side of the connecting member 4, and the first side of the connecting member 4 and the second side of the connecting member 4 are opposite to each other.

[0128] The positional relationship between the solenoid valve assembly and the air pump body 1 can be understood as that the first solenoid valve 5 and the second solenoid valve 6 are arranged close to the side of the air pump body 1 where the intake pipe 2 protrudes. At this time, the first side of the connecting member 4 faces the side where the intake pipe 2 protrudes. Correspondingly, the air outlet passage 41, the first intake passage 42, and the second intake passage 43 are located on the side of the solenoid valve assembly away from the side of the air pump body 1 where the intake pipe 2 is provided, that is, the second side of the connecting member 4 is away from the side where the intake pipe 2 protrudes. This can reduce the distance between the solenoid valve assembly and the air pump body 1, improve the space utilization rate, and further reduce the volume of the driving assembly. At the same time, referring to Figure 9 shown, by arranging in this way, when the intake pipe 2 is arranged, it can be connected to the solenoid valve assembly only through one bend, so that the gas can flow more smoothly in the intake pipe 2.

[0129] In one embodiment, as Figures 6 to 8As shown, the connecting member 4 includes a first air inlet joint 45, a second air inlet joint 431, an air outlet joint 411 and a member body. The first air inlet joint 45, the second air inlet joint 431 and the air outlet joint 411 are all connected to the member body. The first air inlet joint 45 has a first air inlet passage 42 inside, the second air inlet joint 431 has a second air inlet passage 43 inside, and the air outlet joint 411 has an air outlet passage 41 inside. The member body has a central passage 44 extending in a first direction. The air outlet passage 41, the first air inlet passage 42 and the second air inlet passage 43 are respectively communicated with the central passage 44. The first direction is the arrangement direction of the first solenoid valve 5 and the second solenoid valve 6. In combination with as Figure 6 and 8 Understood, the first direction is the direction shown by the y-axis in the three-dimensional coordinate system, the second direction is the direction shown by the x-axis in the three-dimensional coordinate system, and the third direction is the direction shown by the z-axis in the three-dimensional coordinate system. The first direction, the second direction and the third direction are perpendicular to each other in pairs.

[0130] The member body can be understood as a sheet-like structure connected to the first solenoid valve 5 and the second solenoid valve 6. The first air inlet joint 45, the second air inlet joint 431 and the air outlet joint 411 can be integral parts integrally formed with the member body, or can be independent parts respectively connected to the member body. In some embodiments, the first air inlet joint 45, the second air inlet joint 431 and the air outlet joint 411 respectively protrude from the body to facilitate connection with the breast pump 9 and the air pump.

[0131] The central passage 44 of the member body extending in the first direction can be understood as the passage of the member body from left to right as shown in Figure 6 . A partial area at the central position of the central passage 44 is communicated with the air outlet passage 41, and the member body is provided with a first air inlet passage 42 and a second air inlet passage 43, both of which are arranged along the Figure 6 up and down direction. The first air inlet passage 42 and the second air inlet passage 43 are respectively located on the left and right sides of the air outlet passage 41. It can be understood that in order to facilitate the processing of the central passage 44, Figure 6 in, a central passage 44 can be drilled from the left side of the member body, and then the opening on the left side can be blocked with steel balls or the like.

[0132] In one embodiment, the first solenoid valve 5 is connected between the first air inlet passage 42 and the central passage 44 to control the on-off between the first air inlet passage 42 and the central passage 44, and the second solenoid valve 6 is connected between the second air inlet passage 43 and the central passage 44 to control the on-off between the second air inlet passage 43 and the central passage 44. With such a setting, the on-off states between the first air inlet passage 42, the second air inlet passage 43 and the central passage 44 can be respectively controlled by the first solenoid valve 5 and the second solenoid valve 6.

[0133] According to the embodiment of the present disclosure, the distances of gas flowing through the first air inlet passage 42 and the second air inlet passage 43 can be made equal, so that the negative pressure generated by the breast pump 9 connected to the two for sucking milk is the same, further improving the user experience. By providing the first air inlet connector 45, the second air inlet connector 431 and the air outlet connector 411, it is convenient to connect the drive assembly with the breast pump 9 and the air pump. At the same time, compared with the structure with multiple air outlet connectors 411, this embodiment can reduce the vibration and noise caused by the airflow of the outlet.

[0134] In one embodiment, the first solenoid valve 5 and the second solenoid valve 6 are connected to a first side of the component body, and the central passage 44, the first intake passage 42 and the second intake passage 43 are located on a second side of the component body opposite to the first side.

[0135] It is understandable that Figure 6 In the figure, the first side of the component body can be understood as the lower side of the component body, the second side of the component body can be the upper side of the component body, the first solenoid valve 5 and the second solenoid valve 6 are connected to the lower side of the component body, and the central passage 44, the first air intake passage 42 and the second air intake passage 43 are arranged on the upper side of the component body.

[0136] According to the embodiments of the present disclosure, the structure of the solenoid valve assembly can be standardized, the length of the pipeline can be reduced, the space utilization rate can be improved, and the volume of the drive assembly can be reduced.

[0137] In one embodiment, please combine Figure 6 and Figure 7 The component body is provided with a first sub-channel 46 extending along the second direction and a first annular channel 48 arranged around the first sub-channel 46; the first sub-channel 46 and the first annular channel 48 are located on the side of the central passage 44 facing the first solenoid valve 5, and the first sub-channel 46 is connected with the central passage 44, and the end of the first sub-channel 46 away from the central passage 44 has a first opening 47; the first intake passage 42 extends to be connected with the first annular channel 48, and the end of the first annular channel 48 away from the first intake passage 42 has a first annular opening 49; the valve core 52 of the first solenoid valve 5 can move relative to the component body to close the first opening 47 and the first annular opening 49, or to connect the first opening 47 and the first annular opening 49.

[0138] like Figure 6 , Figure 7As shown, it can be understood that the part body has a first sub-channel 46 in the up and down direction (the second direction). A first annular channel 48 is arranged around the first sub-channel 46. The upper end of the first sub-channel 46 communicates with the central passage 44. A first opening 47 is provided at the lower end of the first sub-channel 46. The upper end of the first annular channel 48 communicates with the first air inlet passage 42. A first annular opening 49 is provided at the lower end of the first annular channel 48. The valve core 52 of the first solenoid valve 5 can move up and down relative to the part body. When the valve core 52 of the first solenoid valve 5 moves upward and abuts against the first opening 47 and the first annular opening 49, the first opening 47 and the first annular opening 49 are closed, that is, the first sub-channel 46 and the first annular channel 48 are not communicated, and thus gas cannot flow through the first air inlet passage 42 (i.e., the solenoid valve is in the closed state), and the breast pump 9 cannot form a negative pressure environment. When the valve core 52 of the first solenoid valve 5 moves downward, a gap is formed between the valve core 52 of the first solenoid valve 5 and the first opening 47 and the first annular opening 49 (such as Figure 7 ), the first sub-channel 46 communicates with the first annular channel 48 through the gap (i.e., the solenoid valve is in the open state), and thus gas can flow through the first air inlet passage 42. In some embodiments, as Figure 6 shown, Figure 6 the solenoid valve on the left is in the open state, and the solenoid valve on the right is in the closed state.

[0139] In some embodiments, as Figure 6 、 Figure 7 shown, the first solenoid valve 5 may include a valve body 51, a valve core 52, an electromagnet 53 and a spring 54. The valve core 52 is slidably assembled in the chamber of the valve body 51. The spring 54 is arranged at one end of the chamber away from the first opening 47 and is connected to the valve core 52. The electromagnet 53 is arranged at one end of the chamber away from the first opening 47. By energizing the magnet to generate a suction force for adsorbing the valve core 52, the valve core 52 moves downward and compresses the spring 54 to communicate the first opening 47 and the first annular opening 49. After the magnet is de-energized, the spring 54 releases elastic force to push the valve core 52 upward to close the first opening 47 and the first annular opening 49. The configuration and structure of the second solenoid valve 6 may be the same as those of the first solenoid valve 5. For details, reference may be made to the above embodiments and will not be elaborated here.

[0140] According to the embodiments of the present disclosure, the opening or closing of the solenoid valve assembly can be controlled.

One end of the second sub-channel facing away from the central passage 44 has a second opening; the second intake passage 43 extends to communicate with the second annular channel, and one end of the second annular channel facing away from the second intake passage 43 has a second annular opening; the valve core 52 of the second solenoid valve 6 can move relative to the body of the part to close the second opening and the second annular opening, or to communicate the second opening and the second annular opening.
