[0002] The main component of the breast pump is the breast pump host, the tee joint with the breast pump cover, and the connecting air pipe for connecting the breast pump host and the tee joint. When pumping, the air pump of the breast pump host works and provides negative pressure for the tee joint through the air pipe, and then the breast pump cover on the tee joint is attached to the mother's breast to perform negative pressure breast pumping, and the milk flows to the collection container such as a feeding bottle through the through hole on the tee joint.

[0003] The applicant previously applied for a Chinese invention application "a breast pump host capable of automatically identifying breast pumping demand and a breast pump" with application number CN202411169607.2, which can automatically identify breast pumping demand and correspondingly proposes an external pipe with triggering function that can be inserted with the straight pipe of the breast pump host, especially proposes an external pipe assembled with a ring-shaped magnet, which is used for inductive identification by the corresponding Hall sensor on the breast pump host when the external pipe is inserted, so that the breast pump host can automatically identify the insertion action.

[0004] However, when designing the structure of the external pipe, it only simply sets an annular opening groove for placing the ring-shaped magnet, which is easy to cause the magnet to fall off and displace, and has adverse effects on the accurate identification of the breast pump host to the breast pumping demand (insertion action).

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] Please refer to Figures 1-4 A breast pump Hall trigger tubular connecting piece, comprising a pipe body 1, one end of the pipe body 1 is a plug-in end 101. The pipe body 1 is formed with an outwardly protruding mounting portion 2 near the plug-in end 101, the mounting portion 2 is formed with an accommodating groove 3 opening towards the plug-in end 101 direction, and the accommodating groove 3 is installed with a trigger magnet 4.

[0027] When applied to, for example, the communication between the breast pump host and the breast pump tee, the plug-in end can be used for plugging into the corresponding plug-in port on the breast pump host, and the trigger magnet can be inducted by the corresponding Hall sensor on the breast pump host, so that the breast pump host can automatically identify the plugging action, and then make corresponding identification control.

[0028] The accommodating groove 3 is formed with a fastening groove 5 extending to the pipe body 1 on the side wall close to the pipeline in the pipe body 1. The fastening groove 5 has a first extension groove 6 extending beyond the accommodating groove 3 in the direction away from the plug-in end 101. As shown in Figure 2 , the first extension groove 6 extends beyond the accommodating groove 3 to the right.

[0029] The fastening groove 5 also has a second extension groove 7 extending beyond the trigger magnet 4 in the direction close to the plug-in end 101. The side of the second extension groove 7 away from the pipeline in the pipe body 1 is provided with an opening to form an outer opening 701. As shown in Figure 2 , the second extension groove 7 extends beyond the trigger magnet 4 to the left.

[0030] The magnet fastener 8 is installed on the fastening groove 5. The magnet fastener 8 has a first fastening wing 9 inserted into the first extension groove 6. The magnet fastener 8 also has a second fastening wing 10 placed into the second extension groove 7. The outer side of the second fastening wing 10 extends out of the outer opening 701 of the second extension groove and is connected to the mounting part 2 after covering the trigger magnet 4.

[0031] As shown in Figure 2 , the side wall of the second extension groove 7 close to the plug-in end 101 is formed with a resisting part (or resisting step) for resisting the movement of the second fastening wing 10 in the direction close to the plug-in end 101. The inner wall of the first extension groove 6 is formed with a resisting part (or resisting step) for resisting the outward turning of the first fastening wing 9. After the magnet fastener 8 is connected to the pipe body 1, the magnet fastener 8 is not easy to be separated from the pipe body 1 and can more stably ensure the fixed position of the magnet fastener 8.

[0032] The displacement space of the trigger magnet 4 is limited in the covering space when the trigger magnet 4 is covered and prevented from being separated by the covering structure formed by the part of the second fastening wing 10 extending out of the outer opening and the mounting part 2. When the plug-in end 101 is used, the trigger accuracy of the trigger magnet 4 is effectively ensured when plugging.

[0033] As shown in Figure 3 , 4 , in some embodiments, the accommodating groove 3 is a ring-shaped accommodating groove, and the trigger magnet 4 is a ring-shaped magnet. The pipeline inside the pipe body 1 passes through the ring of the ring-shaped accommodating groove.

[0034] The first extension groove 6 is a ring-shaped extension groove, and the first fastening wing 9 is a ring-shaped fastening wing.

[0035] The second extension groove 7 is a ring-shaped extension groove, the outer opening 701 is a ring-shaped opening, and the second fastening wing 10 is a ring-shaped fastening wing. The fastening effect is better.

[0036] In this embodiment, after the trigger magnet 4 is installed on the magnet fastener 8, the tube body 1 is set on the magnet fastener 8 by a sleeve forming method.

[0037] In the preparation, the magnet fastener 8 with the first fastening wing 9 and the second fastening wing 10 is formed first, then the trigger magnet 4 is installed on the magnet fastener 8 at the corresponding position to form a preform, and then the preform is put into a mold to sleeve form the tube body 1 with the installation part, so as to obtain the Hall trigger tube connector of the breast pump.

[0038] Preferably, the magnet fastener 8 and the tube body 1 are both made of thermoplastic material. For example, the magnet fastener 8 and the tube body 1 are both made of TPU material. Through the hot melt adhesion of the thermoplastic material, after the sleeve forming of the tube body 1, the magnet fastener 8 and the tube body 1 can form a relatively fastened connector.

[0039] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the involved claims.
