When it is sleeved on the second protrusion 215, a space for accommodating gas can be formed between the diaphragm 211 and the spacer 211, which can block the gas flow between the third through hole 2123 and the first joint 11. Therefore, when the user attaches the cup body 122 to the breast, the suction of the pump 62 can be adjusted by the control unit 64. When the pump 62 is connected to the hollow conduit 23 and generates suction, it actually extracts the air between the spacer 212 and the diaphragm 4. Through the combination of the extension 211 and the fastener 24, the tightness between the cover 21 and the first joint 11 can be increased to prevent the extracted air from leaking out from the joint, so that the pressure inside the adapter 1 changes. Because the tightness between the cover 21 and the first joint 11 is good, the suction strength of the pump 62 can be adjusted to correspond to the pressure value inside the adapter 1. The diaphragm 4 undergoes periodic contraction and expansion deformation, which causes the pressure in the cavity of the adapter 1 to change accordingly, thereby generating suction to stimulate the breast and absorb milk. The absorbed milk enters the space of the adapter 1 through the cup body 122. When the diaphragm 4 continues to contract and expand, the structure of the second protrusion 215 and / or the first protrusion 214 and the groove 216 will prevent the diaphragm 4 from completely covering the third through hole 2123 when contracting, thereby preventing the formation of a vacuum-tight state. In addition, due to the barrier effect of the diaphragm 4, milk can be prevented from entering the hollow conduit 23 through the third through hole 2123, and will enter the milk collection bottle 3 through the opening of the third joint 13 for storage.

[0106] In the embodiment of the electric breast pump of the present invention including the check valve 5, the check valve 5 can be combined with the third joint part 13, and the milk passes through the opening of the third joint part 13 and then passes through the check valve 5. The check valve 5 can prevent the milk entering the milk collecting bottle 3 from being sucked back to the first joint part 11 or the second joint part 12 by suction, causing contamination or mechanical damage.

[0107] In summary, through the improvement of the electric breast pump connector and the components and structures of the electric breast pump having the connector of the present invention, users can assemble it more easily and accurately. In addition to being less likely to cause deformation or wear during disassembly and assembly, the electrical connection can also be firmly connected during use without being interrupted by vacuum vibration or device movement.

[0108] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone skilled in the art may modify and alter the above embodiments without violating the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be as set forth in the claims.
