Embodiment Construction

[0010] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0011] figure 1 Shown is the structural representation of the present invention.

[0012] The present invention comprises a cup body 1, an inner liner 2, an insulating layer 3 and a cup cover 4.

[0013] The liner 2 is in the shape of a spiral tube, and the spiral tube is coiled in the cup body 1 .

[0014] One end of the spiral tube communicates with the water outlet, and the other end communicates with the air guide hole 5. The air guide hole 5 is arranged at the upper edge of the cup body 1 to ensure smooth water inlet and outlet.

[0015] The spiral tube of the inner bag 2 is made of stainless steel or glass.

[0016] An insulating layer 3 is arranged between the cup body 1 and the inner container 2, and the insulating layer 3 is filled with an insulating material.

[0017] The inner layer of the cup cover 4 cooperates with the upper edge o...
