The bottle cap made of silicone plastic cannot meet the demand for long-term insulation when in use. To address the above problems, the prior art provides an insulation plug with embedded vacuum glass, an insulation layer of foam, cork and other materials and a plastic shell. Although the insulation effect is improved compared with the traditional bottle plug, the bottle plug is often pulled out and easily falls off, and the vacuum glass embedded in the bottle plug is easy to break and needs to be replaced, which increases the expenditure cost.

[0029] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0030] See also Figures 1 to 5 The utility model provides a knob-type vacuum insulation cover that is easy to install, including a cover core 1, a buffer connector 3 and a cover body 2; the cover core 1 includes an inner core 101 and an outer core 102; the inner core 101 and the outer core 102 are both vacuum cavities made of metal materials, the inner core 101 is used to be inserted into the bottle mouth of the heat preservation device, and the outer core 102 is used to be sleeved on the outside of the bottle mouth of the heat preservation device, and the outer core 102 is connected to the top of the inner core 101 to form an integrated vacuum cavity; the cover body 2 is a cup-shaped hollow structure, the buffer connector 3 is fixedly connected to the inside of the cover body 2, and includes a buffer gasket 301 and a clamping sleeve 302; the buffer gasket 301 is fixedly connected to the inner side of the top wall of the cover body 2; the clamping sleeve 302 is fixedly connected to the side of the cover body 2 The bottom end of the side wall of the snap-in sleeve 302 protrudes inward to form an annular protrusion for snap-fitting and fixing the outer core 102, and the annular protrusion is provided with an internal thread. The present application designs the cover core 1 to be a vacuum cavity in which the inner core 101 and the outer core 102 are connected at the top, and installs a buffer connector 3 between the cover core 1 and the cover body 2, and designs the buffer connector 3 to be a buffer gasket 301 and a snap-in sleeve 302, and completes the snap-fitting and fixing of the cover core 1 through the annular protrusion on the side wall of the snap-in sleeve 302. The vacuum insulated cover core 1 made of metal has the inner core 101 attached to the inner wall of the bottle mouth and the outer core 102 attached to the outer wall of the bottle mouth when the insulation device is closed. The increased metal side wall increases the distance of metal heat conduction, reduces the heat transfer efficiency of the side wall of the cover core 1, and increases the insulation effect.

[0031] In this embodiment, please refer to Figure 3The bottom side of the side wall of the inner core 101 is provided with an inwardly recessed annular reinforcement groove, and a sealing ring 103 is sleeved in the annular reinforcement groove. The present application provides an inwardly recessed annular reinforcement groove on the side wall of the inner core 101 and sleeves the sealing ring 103 in the reinforcement groove. While strengthening the supporting strength of the side wall of the inner core 101, the installation of the sealing ring 103 increases the fit between the cap core 1 and the bottle mouth of the insulation device, thereby avoiding exposure of hot air and increasing the insulation effect.

[0032] In this embodiment, please refer to Figure 3 An annular gasket 104 is sleeved at the connection between the inner core 101 and the outer core 102. The present application provides a buffer between the cap core 1 and the bottle mouth by adding the annular gasket 104, thereby avoiding the friction between the hard cap core 1 and the bottle mouth and increasing the durability.

[0033] In this embodiment, please refer to Figures 1 to 3 The middle part of the inner core 101 is fixedly connected with an air pressure tube 4, and a circular through hole is opened in the middle part of the buffer gasket 301, and a sealing gasket 5 is installed in the circular through hole; the sealing gasket 5 cooperates with the air pressure tube 4, and the top wall of the inner core 101 is recessed inward to form a receiving cavity with the buffer gasket 301, and the air pressure tube 4 runs through the upper and lower ends of the inner core 101, and the top end extends upward to cooperate with the sealing gasket 5. The present application forms a receiving cavity by designing the top wall of the inner core 101 to be recessed inward to cooperate with the buffer gasket 301, and the air pressure tube 4 is installed in the inner core 101, and the buffer gasket 301 is A sealing gasket 5 is installed at the circular through hole to cooperate with the air pressure tube 4. When the cover body 2 is closed, the cover core 1 moves upward under the upward thrust of the bottle mouth until it fits on the buffer gasket 301. At the same time, the air pressure tube 4 is close to the sealing gasket 5, and the air pressure tube 4 is in a closed state. When the cover body 2 is opened, the cover body 2 moves upward to drive the sealing gasket 5 away from the air pressure tube 4. The air pressure tube 4 is in an open state, pre-balancing the pressure difference between the inside and outside of the insulation device. As the cover body 2 continues to move upward, the annular protrusion on the side wall of the clamping sleeve 302 contacts the bottom end of the outer core 102, and exerts an upward force on the outer core 102, driving the cover core 1 to separate from the bottle mouth.

[0034] In the present embodiment, the air pressure tube 4 located in the middle of the inner core 101 is a bent structure (not shown in the figure). By bending and stretching the air pressure tube 4 located inside the inner core 101, the length of the air pressure tube 4 inside the inner core 101 is increased. The increase in the heat conduction distance of the air pressure tube 4 reduces the heat transfer efficiency. The air pressure tube 4 can also be thinned and bent in the vertical direction to reduce the total amount of air in the air pressure tube 4 and reduce the air heat transfer efficiency. At the same time, the air pressure tube 4 bent in the vertical direction suppresses the internal air convection and further reduces the heat transfer efficiency from the air, thereby ensuring the thermal insulation effect.

[0035] In this embodiment, please refer to Figure 5The sealing gasket 5 is a boss-like structure, and the top of the boss bulges outward to form a hemispherical structure. When the hemispherical structure of the boss of the sealing gasket 5 is pressed against the top of the air pressure tube 4, a part of it enters the interior of the air pressure tube 4, completing the sealing of the air pressure tube 4 and increasing the sealing effect. When the hemispherical structure is away from the air pressure tube 4, the hemispherical structure detaches from the air pressure tube 4 and the air pressure tube 4 can be opened.

[0036] The utility model further provides a heat preservation device, which adopts the above-mentioned knob-type vacuum insulation cover which is easy to install, and further comprises a vacuum insulation bottle body 6.

[0037] In summary, the utility model overcomes various shortcomings in the prior art.
