DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-2 A three-way quick connector includes a male connector structure and a female connector structure. One end of the male connector structure is inserted into the female connector structure. The male connector structure includes a male body 1. Three male docking cores 3 are clamped in the male body 1. One end of the male docking core 3 located in the male body 1 is fixedly sleeved with a first sealing ring 2. One side of the first sealing ring 2 abuts against the inner wall of the male body 1 to ensure the sealing of the male docking core 3. A male valve core 6 is slidably connected to the male docking core 3 through a first spring 4. A second sealing ring 5 is fixedly sleeved on the male valve core 6 to ensure the sealing of the male valve core 6.

[0020] In this embodiment, the female connector structure includes a female body 7, the top of the female body 7 is slidably connected to a button 9 through a plurality of second springs 8, which is used to control the disassembly and assembly of the male connector structure and the female connector structure. One end of the female body 7 is clamped with three female docking cores 14, and the bottom of the button 9 is fixedly connected with a plurality of clamping rings. The outer surfaces of the male docking core 3 and the female docking core 14 are provided with a plurality of clamping grooves corresponding to the clamping rings, which facilitate the installation and fixing of the male connector structure and the female connector structure.

[0021] In this embodiment, a fifth sealing ring 15 is fixedly sleeved on one end of the female docking core 14 away from the female main body 7 to ensure the sealing at the female docking core 14. A fourth sealing ring 13 is fixedly sleeved on the female docking core 14. One side of the fourth sealing ring 13 is in contact with the inner wall of the female main body 7 to ensure the sealing at the female docking core 14.
