[0039] See also Figure 1 and Figure 2 , Figure 1 is a stereogram of a first connector provided in an embodiment of the present application; Figure 2 This is a connection diagram when the connector is connected to the hose.

[0040] like Figure 1 As shown, Figure 1 The device comprises a connector 1 , which comprises a three-way connector 10 and a gas path blocking portion 20 arranged on the three-way connector 10 .

[0041] like Figure 2 As shown, Figure 2 The middle connector 1 is connected to a first tube 2 , a first hose 3 , and a second hose 4 .

[0042] In some embodiments, the first port of the three-way connector 10 is used to connect to the first tube 2, the first tube 2 is used to connect to the negative pressure source, the second port 15 of the three-way connector 10 is used to connect to the first hose 3, and the third port 16 of the three-way connector 10 is used to connect to the second hose 4.

[0043] Optionally, the negative pressure source may be a host including a negative pressure pump, and the negative pressure pump includes but is not limited to a piezoelectric pump, a diaphragm pump, a hydraulic pump, a mechanical pump, and the like.

[0044] Optionally, the first tube 2 may be a hose or a hard tube, which is not limited in the present application.

[0045] Optionally, the first tube 2 further includes a host connector 201, and the host connector 201 is used to connect to the host in the breast pump.

[0046] In some embodiments, the first port is in communication with the second port 15 and the third port 16 .

[0047] In some embodiments, the gas path blocking portion 20 is used to squeeze the first hose 3 or the second hose 4 to block the gas path in the first hose 3 or the second hose 4 .

[0048] For example, Figure 2 2 is a schematic diagram of the gas path stopping portion 20 for stopping the first hose 3, but it can be understood that the present application is not limited thereto. Figure 2 The middle gas path stopping portion 20 is used to stop the second hose 4, and when necessary, the gas path stopping portion 20 can also be used to stop the first tube 2, which is not limited in the present application.

[0049] See also Figures 1 to 3 , Figure 3 is a top view of the connector provided in the embodiment of the present application. Figures 1 to 3 As shown, the three-way connector 10 includes a first end 11, a second end 12 and a third end 13, the first port is arranged at the first end 11, the second port 15 is arranged at the second end 12, the third port 16 is arranged at the third end 13, and the gas path stopper 20 is arranged between the second end 12 and the third end 13.

[0050] Please refer to Figure 4 , Figure 4 yes Figure 3 The enlarged schematic diagram of A in FIG. Figure 1 , Figure 3 and Figure 4 As shown, the gas path blocking portion 20 includes a first clamping arm 21A and a second clamping arm 22A, and a clamping opening 23A between the first clamping arm 21A and the second clamping arm 22A is configured to be used for squeezing the first hose 3 or the second hose 4.

[0051] In some embodiments, the first clamp arm 21A is connected to the second end 12 , and the second clamp arm 22A is connected to the third end 13 .

[0052] In some embodiments, the first clamping arm 21A is provided with a first limiting portion 211A facing the second clamping arm 22A, and the second clamping arm 22A is provided with a second limiting portion 221A opposite to the first limiting portion 211A, and the first limiting portion 211A and the second limiting portion 221A are used to prevent the hose inserted into the clamping port 23A from falling off.

[0053] The first limiting portion 211A and the second limiting portion 221A can prevent the hose inserted into the bayonet 23A from falling off when the breast pump is sucking milk, thereby ensuring the engagement effect of the bayonet.

[0054] Please refer to Figure 4 In some embodiments, the first clamping arm 21A is also provided with a first opening portion 212A for facilitating the engagement of the hose, and the second clamping arm 22A is provided with a second opening portion 222A corresponding to the first opening portion 212A. The first opening portion 212A and the second opening portion 222A can assist the user in aligning and engaging the hose into the clamping port 23A.

[0055] In some embodiments, at least one of the first clamp arm 21A and the second clamp arm 22A is elastically connected to the three-way connector 10 or the first clamp arm 21A and the second clamp arm 22A are elastically connected to each other, so that the first hose 3 or the second hose 4 is elastically clamped when clamped on the first clamp arm 21A and the second clamp arm 22A.

[0056] Specifically, when the hose enters the bayonet 23A, at least one of the first clamp arm 21A or the second clamp arm 22A or the connection between the first clamp arm 21A and the second clamp arm 22A is elastically deformed, thereby continuously applying an elastic force to the hose.

[0057] It is understandable that if the unnecessary hose is not sealed during single-sided milk pumping, the host, i.e., the negative pressure source, will be unable to transmit negative pressure to the connected milk storage container, thereby causing milk pumping failure. With the above structure, the user does not need to remove the unnecessary hose during single-sided milk pumping, and can directly snap the hose into the snap-in 23A, thereby saving the user's operating time and making the breast pump more convenient to use.

[0058] Please refer to Figure 5 and Figure 6 , Figure 5 is a stereogram of a second connector provided in an embodiment of the present application, Figure 6 yes Figure 5 The enlarged view of point B in the figure.

[0061] The first limiting portion 211B and the second limiting portion 221B can prevent the hose inserted into the bayonet 23B from falling off when the breast pump is sucking milk, thereby ensuring the engagement effect of the bayonet.

[0062] Please refer to Figure 6 In some embodiments, the first clamping arm 21B is also provided with a first opening portion 212B for facilitating the engagement of the hose, and the second clamping arm 22B is provided with a second opening portion 222B corresponding to the first opening portion 212B. The first opening portion 212B and the second opening portion 222B can assist the user in aligning and engaging the hose into the clamping port 23B.

[0070] Optionally, the clamping member is disposed on the connecting portion 14 of the tee connector 10 .

[0071] In some embodiments, the clamping member includes an operating part, a resetting part and a clamping part, wherein the operating part is used to move the clamping part away from the outer shell of the three-way joint when subjected to external force, and the resetting part is used to reset the clamping part toward the outer shell of the three-way joint when the external force disappears, so that the clamping part clamps the first hose or the second hose to cut off the air path in the first hose or the second hose.

[0072] The air path in the unused hose can be clamped off by the clamping piece, without removing the hose and plugging the unused port in the connector with a soft rubber plug. The operation is simple and convenient.

[0073] Please refer to Figure 7 , Figure 7 Schematic diagram of a connector provided in an embodiment of the present application connected to a milk storage container. Figure 7 As shown, the second hose 4 is connected to the cover of the milk storage container 30 .

[0074] Optionally, when the air path of the first hose 3 is not interrupted by the air path interrupting portion, the first hose 3 may also be connected to a cover of a milk storage container that is the same as the milk storage container 30 .
