[0029] As Figs. 1 to 3As shown, the embodiment of the present application provides a drip-proof infusion structure. The drip-proof infusion structure 100 can prevent liquid from splashing at the infusion port and spilling outside the container to cause pollution. The drip-proof infusion structure 100 can also solve the problem of liquid leakage of the existing infusion head, which causes stains to accumulate on the surface of the equipment, corrodes the equipment, and increases the difficulty of cleaning and maintenance costs of the equipment. The drip-proof infusion structure 100 includes an infusion head 1, an injection pipe 2, a sealing element 4, and a locking structure 5. The infusion head 1 is nested in the injection pipe 2. By moving the infusion head 1 in the injection pipe 2, the filling of the infusion structure 100 can be controlled. The sealing element 4 is sleeved on the outer periphery of the infusion head 1. The inside of the sealing element 4 can abut against the infusion head 1 to form a seal, thereby solving the problem of liquid leakage of the infusion head 1. One end of the sealing element 4 abuts against the injection pipe 2 to form a seal. The locking structure 5 is a cylindrical structure with a through hole in the middle. The locking structure 5 is sleeved on the outside of the sealing element 4 and connected with one end of the injection pipe 2, and is used to fix the sealing element 4 at one end of the injection pipe 2. The injection pipe 2 is also connected with an input pipe 3. The input pipe 3 is used to inject the liquid to be filled into the injection pipe 2.
[0030] In some embodiments, the infusion head 1 includes a first taper surface 11, a groove 12, and a second taper surface 13. The second taper surface 13 is located at one end of the infusion head 1 close to the container, and is used to guide the filling liquid to converge to the center, so that the filling liquid can be accurately infused into the container below. The groove 12 is located at one end of the second taper surface 13 away from the container. The groove 12 can provide a buffer for the liquid. The liquid in the injection pipe 2 accelerates downward under the action of gravity and is prone to splashing at the infusion port and spilling outside the container. By providing the groove 12 on the infusion head 1, the liquid in the injection pipe 2 flows into the groove 12 and is buffered, so that the falling speed is reduced, and the problem of liquid splashing at the infusion port and spilling outside the container can be effectively prevented. The first taper surface 11 is located on the side of the groove 12 away from the second taper surface 13, and is used for the transition of the two sections of the infusion head 1 with different pipe diameters. The pipe diameter between the first taper surface 11 and the groove 12 is smaller than the pipe diameter on the side of the first taper surface 11 away from the groove 12, so that when the infusion head 1 is pulled up, the liquid in the input pipe 3 can flow into the injection pipe 2.
[0031] In some embodiments, the injection pipe 2 includes an outer pipe 21 and an inner pipe 22.

When the pouring structure is in the blocking state, the pouring head 1 is lowered, the height of the first taper surface 11 is lower than the connection of the input pipe 3 and the injection pipe 2, because the pipe diameter of the side of the first taper surface 11 away from the groove 12 is larger, it can block the input pipe 3, prevent the liquid from entering the injection pipe 2. The protrusion 42 in the sealing piece 4 abuts against the pouring head 1 between the first taper surface 11 and the groove 12, blocks the liquid in the injection pipe 2, prevents the liquid in the injection pipe 2 from flowing downward. The conical hole at the bottom of the sealing body 41 abuts against the second taper surface 13, blocks the liquid remaining in the sealing body 41, prevents the liquid remaining in the sealing body 41 from dripping, through three times of sealing, effectively solves the problem of liquid leakage of the pouring structure 100. When pouring is needed, the pouring head 1 is pulled up, the first taper surface 11 is moved to above the interface of the input pipe 3 and the injection pipe 2, the pouring head 1 no longer abuts against the sealing piece 4. The sealing ring 43 is installed above the protrusion 42, when the sealing piece 4 is connected with the injection pipe 2, the sealing ring 43 is extruded, a seal is formed, preventing the liquid in the injection pipe 2 from overflowing from the connection between the sealing piece 4 and the injection pipe 2.
