[0061] Please refer to Figures 1 to 3 , in some embodiments of the present application, a breast pump 10 proposed in the present application includes: a main body assembly 70, a shield assembly 50, a milk storage assembly 20, and a milk overflow detection device 80.

[0062] The main body assembly 70 includes a control module 71 and a negative pressure mechanism 75 for directly or indirectly applying negative pressure to the shield assembly 50. The milk storage assembly 20 is provided with a milk inlet 223 for milk to flow into the interior of the milk storage assembly 20. The milk overflow detection device 80 is configured to be conducted by milk when milk overflows from the milk storage assembly 20, so that the milk overflow detection device 80 is triggered.

[0063] During the milk extraction process of the breast pump 10, the milk extracted is loaded by the milk storage component 20. When milk overflows, the overflow milk conducts the milk overflow detection device 80, thereby triggering the milk overflow detection device 80. The control module 71 detects that the milk overflow detection device 80 is triggered, and then controls the breast pump 10 to make corresponding responses through the control module 71, such as issuing an alarm or automatically stopping the milk extraction program of the breast pump 10, etc. The control module 71 detects that the milk overflow detection device 80 is triggered. Specifically, when the milk overflow detection device 80 is triggered, that is, the milk overflow information is detected, the milk overflow detection device 80 feeds back information to the control module 71, and the control module 71 controls the breast pump to issue a reminder (alarm or voice) or control the operation of the breast pump according to the feedback information. Controlling the operation of the breast pump includes but is not limited to automatically stopping the milk extraction program.

[0064] In some embodiments of the present application, the milk overflow detection device 80 and the control module 71 can be integrated into a circuit control module to form a main control board.

[0065] Please refer to Figures 3 to 10 , in some embodiments of the present application, the milk overflow detection device 80 further includes a first conductive member 32 and a second conductive member 42. Both the first conductive member 32 and the second conductive member 42 are electrically connected to the milk overflow detection device 80. When milk overflows from the milk storage component 20, at least a part of the first conductive member 32 and the second conductive member 42 come into contact with the milk and are conducted by the milk.

[0066] After the milk overflows from the milk storage component 20, at least a part of the milk comes into contact with the first conductive member 32 and the second conductive member 42 simultaneously. Since the milk has conductivity, when the milk comes into contact with the first conductive member 32 and the second conductive member 42 simultaneously, the first conductive member 32 and the second conductive member 42 can be conducted. Also, since both the first conductive member 32 and the second conductive member 42 are electrically connected to the milk overflow detection device 80, when the first conductive member 32 and the second conductive member 42 are conducted, the milk overflow detection device 80 can be conducted, thereby triggering the milk overflow detection device 80. When the control module 71 detects that the milk overflow detection device 80 is triggered, it controls the breast pump 10 to make corresponding responses, such as issuing an alarm or automatically stopping the milk extraction program of the breast pump 10, etc.

[0067] Please refer to Figures 4 to 5 and Figures 7 to 8 , in some embodiments of the present application, the shield component 50 further includes a connecting member 55, and the first conductive member 32 and the second conductive member 42 are arranged at intervals on the connecting member 55.

[0068] The first conductive member 32 and the second conductive member 42 are spaced apart and disposed on the connecting member 55, so that the first conductive member 32 and the second conductive member 42 can stably stay at the detection position and be in a separated state, so that when milk overflow does not occur, the first conductive member 32 and the second conductive member 42 are in an open circuit state. After the milk overflows from the milk storage assembly 20, it can more smoothly contact the first conductive member 32 and the second conductive member 42, conduct the first conductive member 32 and the second conductive member 42, and thereby improve the reliability of the milk overflow detection device 80 being conducted by the milk.

[0069] Please refer to Figures 2 to 5 , in some embodiments of the present application, the shield assembly 50 includes: a breast shield 54 and a flange 56. The breast shield 54 is connected to the host assembly 70. The flange 56 is connected to the breast shield 54 and is used to fit the breast. Among them, the connecting member 55 is connected to the breast shield 54 and extends in the direction of the milk inlet 223. The first conductive member 32 and the second conductive member 42 are both disposed at least partially along the connecting member 55.

[0070] During the milk sucking process of the breast pump 10, the flange 56 is fitted to the user's breast, and both the first conductive member 32 and the second conductive member 42 extend along the connecting member 55 in the direction of the milk inlet 223. After the milk overflows from the milk storage assembly 20, at least part of the milk contacts the first conductive member 32 and the second conductive member 42 at the same time, thereby conducting the first conductive member 32 and the second conductive member 42, and further conducting the milk overflow detection device 80, so that the milk overflow detection device 80 is triggered. When the control module 71 detects that the milk overflow detection device 80 is triggered, it controls the breast pump 10 to make corresponding responses, such as issuing an alarm or automatically stopping the milk sucking program of the breast pump 10, etc.

[0071] Please refer to Figures 2 to 8 , in some embodiments of the present application, the breast shield 54 is provided with a milk sucking channel 51. The first conductive member 32 and the second conductive member 42 both extend from the outer wall of the milk sucking channel 51 to the connecting member 55. When the breast shield 54 is connected to the host assembly 70, one end of the first conductive member 32 away from the milk storage assembly 20 is conducted with one end of the second conductive member 42 away from the milk storage assembly 20.

[0072] After the milk suction shield 54 is connected to the main unit assembly 70, one end of the first conductive member 32 away from the milk storage assembly 20 is electrically connected to one end of the second conductive member 42 away from the milk storage assembly 20. When milk overflows from the milk storage assembly 20, one end of the first conductive member 32 away from the milk storage assembly 20 and one end of the second conductive member 42 away from the milk storage assembly 20 will simultaneously come into contact with the overflowing milk, thereby causing the first conductive member 32 and the second conductive member 42 to be electrically connected by the overflowing milk. In this way, the first conductive member 32 and the second conductive member 42 are electrically connected both by the main unit assembly 70 and by the overflowing milk, so that a conductive circuit loop is formed between the first conductive member 32 and the second conductive member 42, enabling the milk overflow detection device 80 to detect the current flowing between the first conductive member 32 and the second conductive member 42, thereby triggering the milk overflow detection device 80.

[0073] After the main unit assembly 70 is separated from the shield assembly 50, an open circuit is formed between one end of the first conductive member 32 away from the milk storage assembly 20 and one end of the second conductive member 42 away from the milk storage assembly 20. In this case, even if the first conductive member 32 and the second conductive member 42 are electrically connected by the overflowing milk, the milk overflow detection device 80 will not be triggered.

[0074] It can be understood that if the main unit assembly 70 is separated from the shield assembly 50, it means that the breast pump 10 is not in the milk suction state. In this case, even if the first conductive member 32 and the second conductive member 42 are electrically connected by the overflowing milk, the milk overflow detection device 80 will not be triggered, thus avoiding the mis-triggering of the milk overflow detection device 80 and improving the reliability of the milk overflow detection device 80.

[0075] Please refer to Figures 2 to 5 , in some embodiments of the present application, the main unit assembly 70 is provided with a first electrode member 31 and a second electrode member 41. Both the first electrode member 31 and the second electrode member 41 are electrically connected to the milk overflow detection device 80. When the milk suction shield 54 is connected to the main unit assembly 70, the first electrode member 31 is electrically connected to the first conductive member 32, and the second electrode member 41 is electrically connected to the second conductive member 42.

[0076] After the host component 70 is connected to the breast milk suction shield 54, the first electrode member 31 is connected to the first conductive member 32, and the second electrode member 41 is connected to the second conductive member 42. Also, both the first electrode member 31 and the second electrode member 41 are electrically connected to the milk overflow detection device 80. Therefore, a circuit loop for detecting milk overflow is formed among the milk overflow detection device 80, the first electrode member 31, the second electrode member 41, the first conductive member 32, and the second conductive member 42. When milk overflows from the milk storage component 20, at least part of the overflowed milk contacts both the first conductive member 32 and the second conductive member 42 simultaneously, thereby conducting the first conductive member 32 and the second conductive member 42. Further, a conductive circuit loop is formed among the milk overflow detection device 80, the first electrode member 31, the second electrode member 41, the first conductive member 32, and the second conductive member 42, that is, current can flow in the circuit loop formed among the milk overflow detection device 80, the first electrode member 31, the second electrode member 41, the first conductive member 32, and the second conductive member 42. At this time, the milk overflow detection device 80 can detect the change in the current value, that is, trigger the milk overflow detection device 80.

[0077] Please refer to Figures 7 to 10 , in some embodiments of the present application, the shield assembly 50 further includes: a breast milk suction shield 54. The breast milk suction shield 54 is connected to the connecting member 55. Both the first conductive member 32 and the second conductive member 42 extend from the connecting member 55 to the breast milk suction shield 54. The milk overflow detection device 80 further includes: a first electrode member 31 and a second electrode member 41. The first electrode member 31 and the second electrode member 41 are installed on the host component 70. During use, the host component 70 is connected to the breast milk suction shield 54, the first conductive member 32 is conducted with the first electrode member 31, and the second conductive member 32 is conducted with the second electrode member 41.

[0078] After the breast milk suction shield 54 is connected to the host component 70, the first conductive member 32 is conducted with the first electrode member 31, and the second conductive member 32 is conducted with the second electrode member 41. Further, a complete detection circuit loop is formed among the milk overflow detection device 80, the first electrode member 31, the second electrode member 41, the first conductive member 32, and the second conductive member 42. When milk overflows from the milk storage component 20, the end of the first conductive member 32 far from the milk storage component 20 and the end of the second conductive member 42 far from the milk storage component 20 will simultaneously contact the overflowed milk, thereby conducting the first conductive member 32 and the second conductive member 42 by the overflowed milk. In this way, the first conductive member 32 and the second conductive member 42 are conducted both by the host component 70 and by the overflowed milk, thereby forming a conductive circuit loop between the first conductive member 32 and the second conductive member 42, so that the milk overflow detection device 80 detects the current flowing between the first conductive member 32 and the second conductive member 42, thereby triggering the milk overflow detection device 80.

[0079] In some embodiments of the present application, the first electrode member 31 can serve as the positive electrode of the milk overflow detection device 80, and the second electrode member 41 can serve as the negative electrode of the milk overflow detection device 80.

[0080] Please refer to Figures 2 to 8 , in some embodiments of the present application, the host assembly 70 is provided with a housing 72, and the housing 72 is provided with a first mounting hole 73 and a second mounting hole 74. The first electrode member 31 is mounted in the first mounting hole 73, and the second electrode member 41 is mounted in the second mounting hole 74. After the host assembly 70 is connected to the shield assembly 50, the first mounting hole 73 faces the first conductive member 32, and the second mounting hole 74 faces the second conductive member 42.

[0081] In some embodiments of the present application, the host assembly 70 is provided with a housing 72, the housing 72 covers the shield assembly 50, and the housing 72 is provided with a first mounting hole 73 and a second mounting hole 74. The first electrode member 31 is mounted in the first mounting hole 73 and at least partially exposes to the outside of the housing 72 toward the first conductive member 32. The second electrode member 41 is mounted in the second mounting hole 74 and at least partially exposes to the outside of the housing 72 toward the second conductive member 42.

[0082] The first electrode member 31 and the second electrode member 41 are respectively mounted in the first mounting hole 73 and the second mounting hole 74, and then the first electrode member 31 and the second electrode member 41 are fixed by the housing 72. Since at least part of the first electrode member 31 exposes to the outside of the housing 72 toward the first conductive member 32, and at least part of the second electrode member 41 exposes to the outside of the housing 72 toward the second conductive member 42, therefore, when the host assembly 70 is connected to the breast shield 54, the first electrode member 31 can be electrically connected to the first conductive member 32, and the second electrode member 41 can be electrically connected to the second conductive member 42. The first electrode member 31 and the second electrode member 41 are fixed by the housing 72, thereby ensuring the reliability of the electrical connection between the first electrode member 31 and the first conductive member 32, and ensuring the reliability of the electrical connection between the second electrode member 41 and the second conductive member 42, so that a reliable circuit loop for detecting milk overflow is formed among the milk overflow detection device 80, the first electrode member 31, the second electrode member 41, the first conductive member 32, and the second conductive member 42, improving the reliability of the milk overflow detection device 80.

[0083] Please refer to Figures 2 to 3 and Figures 9 to 10, in some embodiments of the present application, one of the first conductive member 32 and the first electrode member 31 is provided with a first elastic conductive terminal 33, and the other of the first conductive member 32 and the first electrode member 31 is provided with a first card slot 57. One of the second conductive member 42 and the second electrode member 41 is provided with a second elastic conductive terminal 43, and the other of the second conductive member 42 and the second electrode member 41 is provided with a second card slot 58. After the first elastic conductive terminal 33 is snapped into the first card slot 57, the first electrode member 31 is electrically connected to the first conductive member 32. After the second elastic conductive terminal 43 is snapped into the second card slot 58, the second electrode member 41 is electrically connected to the second conductive member 42.

[0084] In some embodiments of the present application, the first elastic conductive terminal 33 is disposed on the first electrode member 31, and the first card slot 57 is disposed on the first conductive member 32. The second elastic conductive terminal 43 is disposed on the second electrode member 41, and the second card slot 58 is disposed on the second conductive member 42.

[0085] During the process of assembling the host assembly 70 and the shield assembly 50 with each other, the host assembly 70 and the shield assembly 50 are brought closer to each other in accordance with a predetermined orientation. During the process of the host assembly 70 and the shield assembly 50 approaching each other, the outer wall of the breast shield 54 presses the first elastic conductive terminal 33 and the second elastic conductive terminal 43, thereby causing elastic deformation of the first elastic conductive terminal 33 and the second elastic conductive terminal 43. When the first elastic conductive terminal 33 reaches the area of the first card slot 57, the first elastic conductive terminal 33 extends into the first card slot 57 under the action of its own elastic force, so that the first elastic conductive terminal 33 is snapped into the first card slot 57 and contacts the first conductive member 32, thereby electrically connecting the first electrode member 31 to a conductive member. Similarly, when the second elastic conductive terminal 43 reaches the area of the second card slot 58, the second elastic conductive terminal 43 extends into the second card slot 58 under the action of its own elastic force, so that the second elastic conductive terminal 43 is snapped into the second card slot 58 and contacts the second conductive member 42, thereby electrically connecting the second electrode member 41 to a conductive member.

[0086] By snapping the first elastic conductive terminal 33 into the first card slot 57 and the second elastic conductive terminal 43 into the second card slot 58, the reliability of the electrical connection between the first electrode member 31 and the first conductive member 32 is improved, and the reliability of the electrical connection between the second electrode member 41 and the second conductive member 42 is improved. And by limiting the first elastic conductive terminal 33 through the side wall of the first card slot 57 and limiting the second elastic conductive terminal 43 through the side wall of the second card slot 58, the reliability of the connection between the host assembly 70 and the shield assembly 50 is improved, and the possibility of loosening between the host assembly 70 and the shield assembly 50 is reduced.

[0087] In some embodiments of the present application, the breast milk suction shield 54 is provided with a first recess at the first card slot 57, and the breast milk suction shield 54 is provided with a second recess at the position of the second card slot 58. After the first elastic conductive terminal 33 is snapped into the first card slot 57, the first elastic conductive terminal 33 is snapped into the first recess. After the second elastic conductive terminal 43 is snapped into the second card slot 58, the second elastic conductive terminal 43 is snapped into the second recess.

[0088] The structural strength of the limiting position of the first elastic conductive terminal 33 is increased through the inner wall of the first recess, and the structural strength of the limiting position of the second elastic conductive terminal 43 is increased through the inner wall of the second recess, further improving the reliability of the connection between the host assembly 70 and the shield assembly 50, and reducing the possibility of loosening between the host assembly 70 and the shield assembly 50.

[0089] Please refer to Figures 9 to 10 , in some embodiments of the present application, after the first electrode member 31 is electrically connected to the first conductive member 32, the first elastic conductive terminal 33 is compressed. After the second electrode member 41 is electrically connected to the second conductive member 42, the second elastic conductive terminal 43 is compressed.

[0090] In some embodiments of the present application, a first elastic conductive terminal 33 is provided at one end of the first electrode member 31 facing the first conductive member 32, and a second elastic conductive terminal 43 is provided at one end of the second electrode member 41 facing the second conductive member 42. After the first electrode member 31 is electrically connected to the first conductive member 32, the first elastic conductive terminal 33 is compressed. After the second electrode member 41 is electrically connected to the second conductive member 42, the second elastic conductive terminal 43 is compressed.

[0091] By providing the first elastic conductive terminal 33 and the second elastic conductive terminal 43, the electrical connection between the first electrode member 31 and the first conductive member 32 and the electrical connection between the second electrode member 41 and the second conductive member 42 can maintain an effective electrical connection even when there is a misalignment between the host assembly 70 and the breast milk suction shield 54, thereby improving the reliability of the milk overflow detection device 80.

[0092] In some embodiments of the present application, the milk storage assembly 20 includes: a milk storage container 21 and a container cover 22. The milk storage container 21 is provided with an opening 211. The container cover 22 is connected to the milk storage container 21 at the opening 211. Among them, the milk storage assembly 20 is provided with an exhaust port 222. The milk overflows to the container cover 22 through the exhaust port 222. During use, the connecting member 55 is connected to the container cover 22.

[0093] The connecting member 55 is connected to the container cover 22, and the first conductive member 32 and the second conductive member 42 are arranged along the connecting member 55, and then the first conductive member 32 and the second conductive member 42 both extend along the connecting member 55 toward the container cover 22. When the milk overflows to the container cover 22, it contacts the first conductive member 32 and the second conductive member 42 at the same time, thereby connecting the first conductive member 32 and the second conductive member 42. When the first conductive member 32 and the second conductive member 42 are connected, the milk overflow detection device 80 can be turned on, thereby triggering the milk overflow detection device 80. When the control module 71 detects that the milk overflow detection device 80 is triggered, it controls the breast pump 10 to make a corresponding response, such as sounding an alarm or causing the breast pump 10 to automatically stop the milk pumping process.

[0094] In some embodiments of the present application, the container cover 22 is provided with a groove 221 which is recessed toward the inside of the milk storage container 21. When in use, the connector 55 extends into the groove 221. The first conductive member 32 and the second conductive member 42 both extend into the groove 221 along with the connector 55.

[0095] When milk overflows from the milk storage assembly 20, it enters the groove 221 and is collected by the groove 221. Since the first conductive member 32 and the second conductive member 42 are both extended into the groove 221 along with the connecting member 55, the first conductive member 32 and the second conductive member 42 can simultaneously contact the milk collected in the groove 221, and then be conducted by the milk in the groove 221, thereby conducting the milk overflow detection device 80 and triggering the milk overflow detection device 80. When the control module 71 detects that the milk overflow detection device 80 is triggered, it controls the breast pump 10 to make a corresponding response, such as sounding an alarm or causing the breast pump 10 to automatically stop the milk pumping process.

[0096] In some embodiments of the present application, a buckle 225 is provided on the inner wall of the groove 221, and the connecting member 55 is connected with the buckle 225. The first conductive member 32 and the second conductive member 42 both extend to the connecting member 55.

[0097] The buckle 225 cooperates with the connector 55 to improve the stability and reliability of the connection between the shield assembly 50 and the milk storage assembly 20. The buckle 225 limits the connector 55 to reduce the shaking of the connector 55, thereby preventing the first conductive member 32 and the second conductive member 42 from loosening at the connector 55, thereby maintaining a good connection state of the conduction circuit that triggers the overflowing milk detection device 80. When the milk conducts the first conductive member 32 and the second conductive member 42, the overflowing milk detection device 80 can be triggered.

[0098] Both the first conductive member 32 and the second conductive member 42 extend to the connecting member 55. The first conductive member 32 and the second conductive member 42 are supported by the connecting member 55, so that the first conductive member 32 and the second conductive member 42 are stably retained in the groove 221. When milk is collected in the groove 221, the first conductive member 32 and the second conductive member 42 can be reliably conducted, thereby improving the reliability of the milk overflow detection device 80.

[0099] In some embodiments of the present application, the exhaust port 222 communicates with the groove 221, and milk overflows through the exhaust port 222 and enters the groove 221.

[0100] When the milk level in the milk storage assembly 20 rises to a certain height, it overflows from the exhaust port 222. Also, since the exhaust port 222 communicates with the groove 221, the milk overflowing from the exhaust port 222 can enter the groove 221, thereby conducting the first conductive member 32 and the second conductive member 42, and triggering the milk overflow detection device 80. When the control module 71 detects that the milk overflow detection device 80 is triggered, it controls the breast pump 10 to make corresponding responses, such as issuing an alarm or automatically stopping the milk pumping program of the breast pump 10, etc.

[0101] Please refer to Figures 4 to 8 , in some embodiments of the present application, the container cover 22 is provided with a convex portion 224. The convex portion 224 extends from the bottom of the groove 221 towards the top of the groove 221, and the exhaust port 222 is provided at the top of the convex portion 224. The top of the convex portion 224 is not higher than the top of the groove 221.

[0102] By providing the convex portion 224 at the container cover 22 and arranging the exhaust port 222 at the top of the convex portion 224, the milk level in the milk storage container 21 will not overflow even if it exceeds the bottom of the groove 221, thereby increasing the milk loading capacity of the milk storage container 21. When the milk level in the milk storage container 21 exceeds the height of the convex portion 224, the milk overflows from the exhaust port 222 and is loaded into the groove 221, thereby conducting the first conductive member 32 and the second conductive member 42 extending into the groove 221, and triggering the milk overflow detection device 80. When the control module 71 detects that the milk overflow detection device 80 is triggered, it controls the breast pump 10 to make corresponding responses, such as issuing an alarm or automatically stopping the milk pumping program of the breast pump, etc.

[0103] To facilitate the user's use of the breast pump 10 and ensure the user experience, the breast pump 10 usually pursues a compact structural shape, so the structure of the breast pump 10 is generally relatively compact. To prevent milk from flowing to the outside or other parts inside the breast pump 10, which may cause dirt or damage to the breast pump 10 and its surrounding environment, and to prevent the milk in the milk storage component 20 from being contaminated, the relevant positions of the breast pump 10, especially at the milk inlet 223 of the milk storage component 20, usually need to ensure tightness. If the electrodes are directly inserted into the inner side of the opening 211, it is not conducive to the tightness of the milk storage component 20 and will also increase the risk of contaminating the milk.

[0104] Insert the first conductive member 32 and the second conductive member 42 into the inner side of the milk inlet 223, and electrically connect the first conductive member 32 to the first electrode member 31 and the second conductive member 42 to the second electrode member 41. Then, the first electrode member 31 and the second electrode member 41 are respectively transferred through the first conductive member 32 and the second conductive member 42, avoiding the first electrode member 31 and the second electrode member 41 from directly extending into the milk storage component 20, thereby preventing the first electrode member 31 and the second electrode member 41 from affecting the tightness of the milk storage component 20 and preventing the first electrode member 31 and the second electrode member 41 from contaminating the milk.

[0105] When the first conductive member 32 and the second conductive member 42 come into contact with the milk of the same whole at the same time, the milk conducts the first conductive member 32 and the second conductive member 42. Also, the first conductive member 32 is electrically connected to the first electrode member 31, and the second conductive member 42 is electrically connected to the second electrode member 41. Therefore, the mutually conductive first conductive member 32 and second conductive member 42 can conduct the first electrode member 31 and the second electrode member 41, thus triggering the milk overflow detection device 80, and the milk overflow detection device 80 then feeds back a signal to the control module 71 so that the breast pump 10 makes a corresponding response.

[0106] Through the transfer of the first conductive member 32 and the second conductive member 42, the installation positions of the first electrode member 31 and the second electrode member 41 are more flexible, facilitating the layout of the internal structure of the breast pump 10. The shapes and materials of the first conductive member 32 and the second conductive member 42 can be flexibly set, which can effectively reduce the impact on the tightness of the milk storage component 20 and prevent the milk from being contaminated.

[0107] In some embodiments of the present application, the first electrode member 31 can be the positive electrode of the milk overflow detection device 80, and the second electrode member 41 can be the negative electrode of the milk overflow detection device 80. The positive electrode of the milk overflow detection device 80 extends to the inner side of the milk inlet 223 through the first conductive member 32 so that the positive electrode can be effectively conducted with the milk.

[0108] The negative electrode of the milk overflow detection device 80 extends to the inside of the milk inlet 223 through the second conductive member 42 so that the negative electrode can be effectively conducted with the milk. When the milk level rises to submerge the ends of the first conductive member 32 and the second conductive member 42 at the same time, the first conductive member 32 and the second conductive member 42 are conducted, that is, the positive electrode and the negative electrode of the milk overflow detection device 80 are conducted with each other, thereby changing the conduction state of the internal circuit of the milk overflow detection device 80, causing the electrical parameters of the internal circuit of the milk overflow detection device 80 to change. By detecting the change of the electrical parameters, the milk overflow detection device 80 can be triggered to generate a feedback signal. After receiving the feedback signal, the control module 71 can make the breast pump 10 make corresponding responses, such as issuing an alarm or automatically stopping the milk sucking program of the breast pump 10, etc.

[0109] In some embodiments of the present application, the first conductive member 32 includes at least one of a first conductive coating, a first conductive silica gel, or a first conductive plastic. The second conductive member 42 includes at least one of a second conductive coating, a second conductive silica gel, or a second conductive plastic.

[0110] In some embodiments of the present application, the first conductive member 32 includes a first conductive coating, and the second conductive member 42 includes a second conductive coating.

[0111] The first conductive coating and the second conductive coating are respectively coated on at least different parts of the connecting member 55. One end of the first conductive coating and the second conductive coating extends along the connecting member 55 to the inside of the milk inlet 223, and the other ends of the first conductive coating and the second conductive coating extend in the direction of the outside of the milk storage assembly 20 and extend to appropriate positions respectively. Here, the appropriate position refers to the positions where the first electrode member 31 and the second electrode member 41 are arranged. The first conductive coating is electrically connected to the first electrode member 31 at the appropriate position, and the second conductive coating is electrically connected to the second electrode member 41 at the appropriate position. The first electrode member 31 and the second electrode member 41 at the appropriate position neither affect the sealing performance of the relevant parts in the breast pump 10, nor cause pollution to the milk, and will not form interference or short circuit with other components in the breast pump 10.

[0112] The first conductive coating and the second conductive coating can be only coated along the connecting member 55, or can be coated along other parts of the shield assembly 50 and the connecting member 55, or can be coated across different components in the breast pump 10. The conductive coatings between different components can form a stable and reliable conduction circuit according to the expected design to ensure that after the milk conducts the first conductive member 32 and the second conductive member 42, an effective conduction is formed between the first electrode member 31 and the second electrode member 41, and the effectiveness of the conduction of the milk overflow detection device 80 is ensured.

[0113] The conduction of the circuit in the circuit is achieved in the form of a conductive coating, which can make the circuit layout change with the change of the shape of the components of the breast pump 10, reducing the impact on the internal structure layout of the breast pump 10. Moreover, the thickness dimension of the conductive coating is small, and thus the impact on the sealing performance between the components of the breast pump 10 can be effectively reduced.

[0114] In some embodiments of the present application, the first conductive member 32 includes first conductive silica gel or first conductive plastic, and the second conductive member 42 includes second conductive silica gel or second conductive plastic.

[0115] Contacting the milk through food-grade conductive silica gel or conductive plastic can avoid milk contamination. Since the conductive silica gel and the conductive plastic have conductivity, an effective conduction can be formed between the first electrode member 31 and the second electrode member 41. The conductive silica gel and the conductive plastic are also deformable, which can effectively adapt to the complex internal structure of the breast pump 10 and reduce the impact on the internal structure layout of the breast pump 10. The conductive silica gel and the conductive plastic can undergo elastic deformation, and thus have less impact on the sealing performance of the internal structure of the breast pump 10. Even through the design of the shape of the conductive silica gel or conductive plastic, the sealing performance of the internal structure of the breast pump 10 can be improved.

[0116] In some embodiments of the present application, the milk storage assembly 20 further includes a one-way valve 60. The one-way valve 60 is connected to the container cover 22. The one-way valve 60 is communicated with the milk inlet 223. The exhaust port 222 is provided on at least one of the container cover 22 and the one-way valve 60.

[0117] During the milk suction process of the breast pump 10, the milk enters the milk storage container 21 through the one-way valve 60 via the milk inlet 223. When the breast pump 10 enters the milk suction stroke, the one-way valve 60 closes, thereby preventing the milk or gas in the milk storage container 21 from being sucked out and entering the milk suction channel 51, so as to ensure that there is sufficient negative pressure in the milk suction channel 51 to suck the milk.

[0118] During the milk suction process of the breast pump 10, a negative pressure is formed in the milk suction channel 51 by the negative pressure device of the breast pump 10. At this time, since the milk suction channel 51 is communicated with the one-way valve 60 through the milk outlet 52, the inside of the one-way valve 60 is also in a negative pressure state. Then, the one-way valve 60 is closed by the air pressure outside the one-way valve 60, so that the milk suction channel 51 is isolated from the milk storage space of the milk storage container 21 through the one-way valve 60, forming a closed space in the milk suction channel 51, ensuring that the milk suction channel 51 is always in a negative pressure state during the milk suction stroke of the breast pump 10, and thus ensuring the effectiveness of the milk suction process of the breast pump 10. Since the one-way valve 60 is in a closed state during the milk suction stroke of the breast pump 10, it can effectively prevent the milk from being sucked into the milk suction channel 51 and prevent the milk from overflowing from the milk inlet 223, improving the anti-overflow performance of the breast pump 10.

[0119] In some embodiments of the present application, the exhaust port 222 may be provided on the container lid 22. The exhaust port 222 may also be provided on the outer wall of the one-way valve 60, or may be provided at the connection between the container lid 22 and the one-way valve 60 to form a gas communication channel, or may be provided at other positions that can discharge the gas in the milk storage assembly 20.

[0120] During the milk pumping process of the breast pump 10, milk enters the milk storage assembly 20. During the accumulation of milk in the milk storage assembly 20, the gas in the milk storage assembly 20 is discharged through the exhaust port 222 so that the milk can smoothly enter the milk storage assembly 20. When the milk in the milk storage assembly 20 approaches or exceeds the exhaust port 222, it will overflow from the exhaust port 222. At this time, at least part of the overflowed milk will conduct the first conductive member 32 and the second conductive member 42, thereby triggering the milk overflow detection device 80. When the control module 71 detects that the milk overflow detection device 80 is triggered, it controls the breast pump 10 to make corresponding responses, such as issuing an alarm or automatically stopping the milk pumping program of the breast pump 10.
