[0027] Reference Figure 1 to Figure 2 , a thermos pot, comprising: a pot body 100, which is a cavity structure with an opening at the top, and the pot body 100 is provided with a first vacuum insulation layer;

[0028] A handle 110 is disposed on the outer side wall of the upper portion of the kettle body 100;

[0029] The pot cover 140 is movably disposed on the handle 110. The pot cover 140 is provided with a second vacuum insulation layer. The shape and size of the pot cover 140 are adapted to the opening. The pot cover 140 can cover the opening and form a heat preservation space in the pot body 100.

[0030] The kettle body 100 and the kettle cover 140 are made of metal material.

[0031] The first vacuum insulation layer and the second vacuum insulation layer can effectively isolate the heat exchange between the outside and the internal liquid, thereby extending the insulation time; the kettle body 100 and the kettle cover 140 are made of metal materials, which can improve the pressure resistance and drop resistance of the thermos kettle and have good durability; the kettle cover 140 can be directly covered on the kettle body 100, and the user only needs to perform simple operations to open and close it, which greatly improves the convenience of use; the use of a bottle cap made of metal can avoid the odor problem caused by plastic; the thermos kettle of this design has relatively large improvements in insulation performance, durability and ease of operation.

[0032] One end of the pot cover 140 is provided with a lug 120, which is rotatably mounted on the handle 110 via a rotating shaft, and the lug 120 is extended in a direction away from the handle 110. The convenience of operation is enhanced, and the user only needs to use one hand to open the pot cover 140.

[0033] The handle 110 is provided with a positioning portion, the lug 120 is clamped to the positioning portion, and the lug 120 is fixed to the positioning portion by welding. The positioning portion can provide an anchor point when the lug 120 is welded, which is convenient for enhancing the connection strength between the lug 120 and the handle 110, thereby improving the service life of the thermos pot as a whole.

[0034] The inner side wall of the top of the kettle body 100 is provided with a limiting portion 160, and the lower outer edge of the kettle cover 140 is provided with a clamping portion 150, which is adapted to the limiting portion 160, and the clamping portion 150 is clamped to the limiting portion 160. The clamping portion 150 and the limiting portion 160 cooperate with each other, and the kettle cover 140 and the kettle body 100 can form a tight sealing structure, effectively reducing the loss of heat and preventing the entry of external pollution, and can also play a guiding role when the lid is closed, which can improve the user experience.

[0035] The clamping portion 150 is in a stepped shape, which can form a tighter and more comprehensive fit, further improving the sealing performance.

[0036] The pot lid 140 is provided with an elastic sealing ring, which is sleeved on the clamping part 150. When the pot lid 140 covers the opening, the elastic sealing ring abuts against the pot lid 140 and the pot body 100 respectively. It can reduce the noise during the opening and closing process and improve the user experience. The elastic sealing ring can also contact the inner side of the pot lid 140 and the pot body 100 respectively through its own elastic force, further improving the thermal insulation performance of the thermos pot. The elastic sealing ring is made of silicone material. Silicone has good temperature resistance and does not produce odor. It can also effectively prevent water leakage when the pot body 100 is tipped over or under pressure. It can be understood that the elastic sealing ring made of silicone is a standard part, which does not need to be re-molded and produced, can save production costs, and is simpler to replace and maintain. Users can easily obtain accessories of the same specifications.

[0037] Support ribs are provided in the second vacuum insulation layer, one end of the support ribs is connected to the top of the pot lid 140, and the other end is connected to the bottom of the pot lid 140. The support ribs can enhance the mechanical strength of the pot lid 140 and effectively extend the service life of the pot lid 140. It is understandable that a plurality of support ribs can form a triangular shape, which can further enhance the mechanical strength and stability of the pot lid 140. The rib structure forms a plurality of small isolation spaces inside the vacuum insulation layer, which further slows down the speed of heat transfer, which is equivalent to adding multiple thermal barriers on the basis of the original vacuum insulation, greatly improving the insulation efficiency of the thermos pot, making the internal temperature change more slowly, and having better insulation or cooling effects.

[0038] The handle 110 is provided with a gripping portion, and the gripping portion is provided with a buffer rubber 130, which is clamped to the gripping portion. The gripping comfort of the handle 110 can be improved, and the installation is simple. Even when the hands are wet or sweaty, the friction between the hands and the handle 110 can be increased to prevent accidental slipping and ensure the safety of the user. The buffer rubber 130 is installed on the handle 110 by clamping, which is simple to install and easier to replace and disassemble in the future.

[0039] The kettle body 100 and the kettle lid 140 are made of stainless steel. Stainless steel has a low thermal conductivity, and with the vacuum insulation layer design, it can effectively block the heat exchange between the outside and the internal liquid, maintain the temperature of the beverage, and has excellent heat preservation or cold preservation effects. The stainless steel surface is smooth and not easy to absorb dirt, so it is very convenient to clean.

[0040] The thermos pot of this embodiment mainly includes three parts: a pot body 100, a handle 110, and a pot lid 140. The pot body 100 is formed in one piece using high-quality 304 stainless steel material, and an opening of moderate diameter is designed at the top. A first vacuum insulation layer is arranged inside the pot body 100 to effectively prevent heat loss. The size design of the pot body 100 is ergonomic and easy to hold and operate. The pot lid 140 is also made of 304 stainless steel material, and its shape is precisely matched with the opening of the pot body 100 to ensure sealing. A second vacuum insulation layer is arranged inside the pot lid 140 to further enhance the heat preservation effect. In particular, a lug 120 structure is built into one end of the pot lid 140, and the lug 120 is connected to the handle 110 on the outside of the upper part of the pot body 100 through a rotating shaft, and the lug 120 extends in a direction away from the handle 110, which is convenient for user operation.

[0041] The handle 110 is not only designed with a gripping portion that is easy to grasp, but also has a soft food-grade buffer rubber 130 embedded in the gripping portion, which is fixed by a snap-on method, which not only improves the comfort of the hand feel, but also effectively prevents slipping and reduces shock, and can be held steadily even with wet hands. In order to enhance the sealing and convenience, a limiting portion 160 is specially provided on the inner side wall of the top of the pot body 100, which matches the snap-on portion 150 designed on the outer edge of the lower part of the pot cover 140. The snap-on portion 150 adopts a stepped structure to ensure that it is tightly combined with the limiting portion 160 and improve the sealing performance. In addition, a circle of food-grade silicone elastic sealing ring is embedded in the pot cover 140, and the sealing ring is sleeved on the snap-on portion 150. When the pot cover 140 is closed, the sealing ring is tightly fitted with the pot cover 140 and the inner wall of the pot body 100, respectively, to further ensure the airtightness of the thermos pot.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
