The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

Fig. 1 to 8 show a thermos according to the invention, which comprises a housing 1, a thermos 2 and a lid 3. The shell 1 is provided with a containing cavity 11 and a communication port 12 communicated with the containing cavity 11, the thermos bottle 2 is provided with a water containing cavity 21 and a communication channel 22 communicated with the water containing cavity 21, the thermos bottle 2 is fixedly arranged in the containing cavity 11 of the shell 1, the mouth of the thermos bottle 2 is fixedly kept in the communication port 12 of the shell 1, the cover body 3 is detachably arranged in the shell 1, and the cover body 3 can seal the communication channel 22 of the thermos bottle 2. After the cap 3 is detached from the case 1, water can be added to the water containing chamber 21 from the communication passage 22 of the thermos bottle 2.

Preferably, the thermos bottle comprises a protective body 4, the protective body 4 has a convex arc surface 41, the protective body 4 is disposed between the bottom of the thermos bottle 2 and the bottom of the casing 1, and the arc surface 41 of the protective body 4 is attached to the outer surface of the bottom of the thermos bottle 2, so that during transportation of the thermos bottle, the protective body 4 can prevent the thermos bottle 2 from shaking in the accommodating cavity 11 of the casing 1, thereby preventing the thermos bottle 2 from being damaged due to continuous shaking. Preferably, the protector 4 is a spherical protector. The protector 4 may be, for example, a hollow spherical protector or a solid spherical protector. For example, the casing 1 may further comprise an outer casing 13 and a lower lid 14 provided at the bottom of the outer casing 13, the protective body 4 being located between the lower lid 14 and the bottom of the thermos 2. Preferably, the outer case 13 is provided with a handle to facilitate the user's use of the thermos.

The lid body 3 includes a lid main body 31, a seal ring 32, a closing body 33, an elastic pressing plate 34, a protection cover 35, and an operating body 36.

The cover main body 31 has an upper space 311 opened upward, a movable passage 312, a water outlet passage 313 and an air inlet passage 314. The sealing ring 32 is provided at the bottom of the cap main body 31 to enable a communication space 37 to be formed between the sealing ring 32 and the cap main body 31. The movable passage 312 extends from the communication space 37 to the upper space 311 of the cover main body 31, so that the movable passage 312 communicates the communication space 37 and the upper space 311. The water outlet passage 313 and the air inlet passage 314 of the cover main body 31 are respectively communicated with the communication space 37, and an opening of the water outlet passage 313 is formed at a side wall of the cover main body 31. Preferably, the opening of the air intake passage 314 is also formed at the side wall of the cover main body 31, for example, the opening of the air intake passage 314 and the opening of the water outlet passage 313 may be formed at the opposite side wall of the cover main body 31. Preferably, the sealing ring 32 may be a bellows, so that the sealing ring 32 can be deformed to ensure the sealing of the thermo jug.

The enclosure 33 includes an enclosure member 331 and an extension post 332 extending from the enclosure member 331. Preferably, the closing element 331 and the extension column 332 of the closing body 33 may be of one-piece construction, for example by means of injection molding the closing element 331 and the extension column 332 of the closing body 33 may be integrally formed. More preferably, the closing element 331 can be a disc-shaped closing element 331, and the outer diameter dimension of the closing element 331 is larger than the inner diameter dimension of the sealing ring 32, so that the closing element 331 can close the bottom opening of the sealing ring 32, thereby closing the communicating space 37 by the closing element 331 to prevent the communicating space 37 from communicating with the water containing cavity 21 of the vacuum flask 2. The extending column 332 of the closing body 33 can extend from the communicating space 37 to the upper space 311 of the cover main body 31 through the movable channel 312 of the cover main body 31, and the closing member 331 can be engaged with the seal ring 32 or away from the seal ring 32 when the extending column 332 moves in the movable channel 312 of the cover main body 31.

The elastic pressing plate 34 has a fixed end 341 and a free end 342 corresponding to the fixed end 341, the elastic pressing plate 34 is located in the upper space 311 of the cover main body 31, and the fixed end 341 of the elastic pressing plate 34 is fixedly mounted on the inner wall of the cover main body 31, and the extending column 332 is fixedly mounted on the free end 342 of the elastic pressing plate 34. For example, the free end 342 of the resilient pressure plate 34 can be provided with a mounting channel 343, and the free end of the extension post 332 can be mounted to the mounting channel 343 of the resilient pressure plate 34.

The protective cover 35 is mounted to the cover main body 31 to close the opening of the upper space 311 of the cover main body 31. The operating body 36 has a pivot end 361 and an operating end 362 corresponding to the pivot end 361, the pivot end 361 of the operating body 36 is rotatably mounted on the protecting cover 35, and the free end 342 of the elastic pressing plate 34 is attached to the pivot end 361 of the operating body 36 in a driving manner.

As shown in fig. 3 and fig. 4, when the operating end 362 of the operating body 36 is pressed by the fingers of the user to drive the operating body 36 to rotate relative to the protective cover 35, the pivot end 361 of the operating body 36 can drive the free end 342 of the elastic pressing plate 34 to move downward, and the extending column 332 of the sealing body 33 can drive the sealing element 331 to move away from the sealing ring 32 during the deformation of the elastic pressing plate 34, so that the communication space 37 can communicate with the water containing cavity 21 of the thermos bottle 2. When pouring water, since the cap body 31 is provided with the air inlet passage 314, the water in the water containing chamber 21 of the thermos bottle 2 can be poured out through the communicating space 37 and the water outlet passage 313 of the cap body 31. In this process, even if the user's fingers do not continuously apply force to the operating body 36, the operating body 36 can be kept in the rotated state by designing the shape of the operating body 36 so that the communicating space 37 is always communicated with the water containing cavity 21 of the thermos bottle 2, thereby facilitating the one-handed operation of the user.

When the user's finger applies force to the operation end 362 of the operation body 36 again to drive the operation body 36 to rotate relative to the protection cover 35, since the pivot end 361 of the operation body 36 does not apply force to the free end 342 of the elastic pressing plate 34, the extending column 332 can drive the sealing element 331 to move towards the sealing ring 32 to be attached to the sealing ring 32 in the process of the elastic pressing plate 34 returning to the initial state, so as to prevent the communication space 37 from being communicated with the water containing cavity 21 of the thermos bottle 2.

Preferably, the cover main body 31 has external threads, the housing 1 has internal threads, and the external threads of the cover main body 31 and the internal threads of the housing 1 are engaged with each other to threadedly mount the cover body 3 to the housing 1.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention, and should not be considered as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
