[0016] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0017] The specific embodiment of the present invention comprises Figure 1 and Figure 2As shown, a multifunctional thermos cup includes an outer shell, an inner liner 2 and a cup cover 3. The inner liner 2 is mounted inside the outer shell. A connector 31 is provided at the bottle mouth of the outer shell. The cup cover 3 is mounted on the connector 31. The outer shell is made of ABS, and the inner liner is made of PC. The inner liner is blow-molded, and the cost is low. The outer shell is divided into a bottle body 1 and a bottom cover 11. The bottle body 1 and the bottom cover 11 are threadedly connected, and an O-ring 5 is embedded at the contact between the bottom of the bottle body 1 and the bottom cover 11. A vacuum nozzle 6 is provided at the bottom of the bottom cover 11. An elastic bracket 21 is provided between the bottom cover 11 and the inner liner 2, which can effectively buffer the impact force generated by shaking. The outer surface of the inner liner 2 is molded and coated with a 0.2mm high-light reflective film instead of silver plating, which can avoid environmental pollution caused by the silver plating process. The cavity between the inner liner 2 and the outer shell is a vacuum cavity 4. There are two inner liner 2 and they are arranged side by side. A multi-purpose switch is also provided near the bottle mouth of the shell. The multi-purpose switch is conical with a cone angle of 120° and is divided into an upper switch 7 and a lower switch 71. The upper switch 7 is provided with a partition 8 extending to the outside of the bottle mouth along the two inner liner dividing lines. The upper switch 7 is movably arranged with the bottle mouth of the shell and sealed with the bottle mouth of the shell. The lower switch 71 is fixed inside the bottle mouth of the shell, and its inner surface abuts against the bottle mouth of the inner liner 2, and its outer surface is provided with an annular protrusion 9. The upper switch 7 is provided with a corresponding annular groove, the groove contacts the protrusion 9, and a sealing ring is provided between the two, so that the sealing effect is good and no water leakage is ensured. A notch is opened at the bottle mouth of the shell, and an elastic rubber 12 is attached to the notch. A handle 72 is provided on the edge of the upper switch 7, and the handle 72 extends into the elastic rubber 12. With this structure, even if a small amount of overflow occurs between the upper switch 7 and the bottle mouth of the shell, the human hand will not come into contact with the overflow, thereby preventing pollution. The multi-purpose switch is provided with a plurality of channels 73 communicating with the interior of the inner container and the outer bottle mouth. The channels 73 can be closed or opened by rotating the handle 72.

[0018] When used specifically, Figure 1 As shown, by opening the cup cover 3, beverages, Chinese medicine decoctions or water of different temperatures can be respectively injected into the two inner tanks 2 in the multifunctional thermos cup. The two inner tanks 2 can be divided into a hot water chamber and a cold water chamber, and a partition 8 is provided to prevent water from mixing during injection. The multi-purpose switch is conical with a cone angle of 120°, which is conducive to injecting water or other liquids. When in use, rotating the handle 72 can make the channel 73 form three states, opening only one hot water channel, opening only the cold water channel, and opening both the cold water and hot water channels at the same time, thereby realizing different functions.

[0019] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
