Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

As shown in fig. 1-3, the present embodiment provides an infusion apparatus connector capable of automatically switching and stopping, including a tube body 1, a protective housing 6 is fixedly connected in the tube body 1, the protective housing 6 is in an "L" shape, wherein the right end of the protective housing 6 is fixedly connected to the inner wall of the tube body 1, and a gap for liquid to pass through is left between the left end of the protective housing 6 and the inner wall of the tube body 1.

A switch control plug 5 is arranged in the tube body 1 in a sliding mode, a first transfusion space 8 and a second transfusion space 9 are formed in the tube body 1 through the switch control plug 5, the first transfusion space 8 is arranged at the upper end of the protective shell 6, and the second transfusion space 9 is arranged at the lower end of the protective shell 6.

The switch control plug 5 is arranged in the protective shell 6 in a sliding mode, the floater 4 is further arranged in the first infusion space 8, the floater 4 is connected with the switch control plug 5 through a connecting line 41, the protective shell 6 is further provided with a through hole for the connecting line 41 to pass through, and the connecting line 41 is arranged in the through hole in a sliding mode.

Wherein, the protective shell 6 plays a role of protecting the switch control plug 5, thereby realizing the interval work of the first transfusion space 8 and the second transfusion space 9. When the first infusion space 8 is filled with liquid, the floater 4 is driven to ascend under the action of the liquid, and the floater can drive the switch control plug 5 to move upwards, so that the first infusion space 8 is communicated with the second infusion space 9.

The first transfusion space 8 is communicated with a first transfusion tube 2, the first transfusion tube 2 is provided with a first exhaust port 21, the second transfusion space 9 is communicated with a second transfusion tube 3, and the second transfusion tube 3 is provided with a second exhaust port 31.
