Description

Technical Field

[0001] The utility model belongs to the field of daily necessities production, and particularly relates to a vacuum heat-insulating cover and a heat preservation device which are convenient to disassemble. Background Art

[0002] At present, most of the heat preservation covers of common heat preservation devices on the market use plastic or silica gel combinations to prevent heat dissipation of the heat preservation devices. For the bottle body of the heat preservation device, double-layer glass or metal with evacuated space is mostly used to prevent heat loss. The bottle caps made of silica gel and plastic cannot meet the requirements of long-term heat preservation during use. In view of the above problems, the prior art provides a heat preservation plug with an embedded vacuum glass, an outer heat insulation layer of materials such as foam and cork, and a plastic shell. Although the heat preservation effect is improved compared with the traditional bottle plug, the bottle plug often falls off easily due to frequent plugging and unplugging, and the embedded vacuum glass in the bottle plug is easy to break and not easy to replace, increasing the expenditure cost. Summary of the Utility Model

[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a vacuum heat-insulating cover and a heat preservation device which are convenient to disassemble, so as to solve the problems in the prior art that the traditional bottle plug has poor heat insulation effect and is not easy to replace when damaged.

[0004] To achieve the above purpose and other related purposes, the present utility model provides a vacuum heat-insulating cover and a heat preservation device which are convenient to disassemble, including a cover core, a cover body and a connecting piece;

[0005] The cover core is a vacuum cavity, the cover core is detachably connected to the cover body through a connecting piece, and the connecting piece applies a pre-tightening force towards the cover body to the cover core.

[0028] The following individual embodiments are only for illustration. Combinations can be made between the individual embodiments, and it is not limited to the content shown in the following single embodiment.

[0029] Please refer to Figures 1 to 4 , the present utility model provides a vacuum heat-insulating cover and a heat preservation device that are easy to disassemble, including a cover core 1, a cover body 2, and a connecting piece 3; the cover core 1 is a vacuum cavity, the cover core 1 is detachably connected to the cover body 2 through the connecting piece 3, and the connecting piece 3 applies a pre-tightening force towards the cover body 2 to the cover core 1. In this application, the cover core 1 is designed as a vacuum cavity to ensure long-term heat insulation. By adding the connecting piece 3, the cover core 1 is detachably connected to the inner side of the top wall of the cover body 2, and the cover core 1 after installation is pressed against the inner side of the top wall of the cover body 2 by the pre-tightening force applied by the connecting piece 3 to the cover core 1. The detachably connected cover core 1 ensures that in case of damage, disassembly, replacement, and repair are convenient.

[0030] In this embodiment, please refer to Figures 1 to 4, a first installation groove 101 with an opening facing the top wall of the cover body 2 is recessed inward at the top end of the cover core 1. One end of the connecting member 3 is fixedly connected to the inner side of the top wall of the cover body 2, and the other end extends into and is connected to the first installation groove 101. In this application, a space for accommodating the connecting member 3 is formed by the first installation groove 101 recessed inward at the top end of the cover core 1 in cooperation with the top wall of the cover body 2, avoiding the connecting member 3 being exposed outside.

[0031] In this embodiment, please refer to Figure 2 and Figure 3 , the connecting member 3 is a clamping member, and the cover core 1 is clamped and fixed to the inner side of the top wall of the cover body 2 through the clamping member. By designing the connecting member 3 as a clamping member, it is convenient to replace and repair the vacuum insulation cover when it is damaged during use.

[0032] In this embodiment, please refer to Figure 3 and Figure 4 , the clamping member includes a spring piece 301 and a spring piece fixing seat 302; several spring pieces 301 are evenly distributed circumferentially along the spring piece fixing seat 302. The spring piece 301 inclines outward, and the end far from the spring piece fixing seat 302 is smoothly folded back inward; the spring piece fixing seat 302 is fixedly connected to the inner side of the top wall of the cover body 2; an annular protrusion is formed inside the first installation groove 101 to cooperate with the outwardly inclined part of the spring piece 301. In this application, the spring piece 301 of the connecting member 3 is designed as an arc-shaped structure protruding outward. Multiple spring pieces 301 protruding outward cooperate with the annular protrusion in the first installation groove 101 to complete the clamping of the cover core 1 and can apply a pre-tightening force towards the cover body 2 to the cover core 1, so that the cover core 1 is tightly attached and fixed to the inner side of the top wall of the cover body 2. When opening the closed vacuum insulation cover, the spring piece 301 deforms with the change of the pulling force, making the pulling force provided for the cover core 1 larger, and the design of multiple spring pieces 301 makes their elasticity related and the force more uniform.

[0033] In this embodiment, please refer to Figure 3 and Figure 4 , several spring pieces 301 share a spring piece fixing seat 302 and are evenly and fixedly connected around the spring piece fixing seat 302. The spring piece 301 and the spring piece fixing seat 302 are integrally formed. In this application, by designing the spring piece 301 and the spring piece fixing seat 302 as an integrally formed structure, it is convenient to install and fix the connecting member 3, and at the same time, the spring piece 301 has stronger stiffness.

[0034] In this embodiment, please refer to Figure 1 and Figure 2, a bottom end of the lid core 1 is recessed inward to form a second installation groove 102, and internal threads are provided inside the second installation groove 102. By providing the second installation groove 102 that is recessed inward at the bottom of the lid core 1 and providing internal threads inside the installation groove, it is used to connect components such as a tea strainer to meet different usage scenarios.

[0035] In this embodiment, please refer to Figure 1 and Figure 5 , the lid body 2 is a cup-shaped hollow structure. The center of the inner side of the top wall of the lid body 2 is fixedly connected to the connecting member 3, and a ring-shaped seal 4 is fixedly connected to the outside of the center of the top wall. In this application, by installing the ring-shaped seal 4 around the connecting member 3 on the inner side of the top wall of the lid body 2, when the heat preservation device is closed, the top wall of the lid core 1 and the top of the bottle mouth of the heat preservation device simultaneously press against the seal 4, avoiding the exposure of hot air and increasing the heat preservation effect.

[0036] The present utility model also provides a heat preservation device. The heat preservation device adopts the above-mentioned detachable vacuum heat insulation lid, and the heat preservation device further includes a vacuum heat preservation bottle body 5.

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

[0038] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not used to limit the present utility model.
