[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0030] For highly insulated thermos flasks, please refer to [link / reference]. Figure 1-4 As shown, it includes: a cup body 100, an inner lid 200 and an outer lid 300. The top of the cup body 100 forms a cup mouth. The inner lid 200 is partially embedded in the cup mouth and screwed on. The outer lid 300 covers the cup mouth and covers the inner lid 200. The outer lid 300 is screwed on to the cup body 100.
[0031] Specifically, the cup body 100 includes an inner layer 110 and an outer layer 120, the inner layer 110 and the outer layer 120 are connected at the top of the cup body 100, and a first gap 101 is formed between the inner layer 110 and the outer layer 120.
[0032] More specifically, the cup body 100 is made of metal, particularly stainless steel. The inner layer 110 and the outer layer 120 are integrally formed by pressing and / or bending. The inner layer 110 and the outer layer 120 are connected at the top of the cup body 100. The first gap 101 is formed on the sides and bottom of the inner layer 110 and the outer layer 120.
[0033] The first gap 101 can effectively block heat from being transferred from the inner layer 110 to the outer layer 120, reducing heat dissipation and thus effectively achieving the heat preservation effect.
[0034] Furthermore, the inner cover 200 includes: an upper shell 210, a lower shell 220, and a heat insulation body 230, wherein the heat insulation body 230 is disposed within the cavity 201 formed by the upper shell 210 and the lower shell 220; between the upper shell 210 and the lower shell 220, one of them is provided with a slot and the other is provided with a hook, and the two are fastened together.
[0035] The lower shell 220 is an open-topped, roughly bowl-shaped shell, while the upper shell 210 is fitted on top of the lower shell 220. The heat insulation body 230 is fitted inside the cavity 201 formed by the upper shell 210 and the lower shell 220, which serves to block heat dissipation, i.e., to provide heat insulation.
[0036] Specifically, the lower shell 220 can be supported by plastic material. Generally speaking, the thermal conductivity of plastic material is weaker than that of metal material. The upper shell 210 can be made of metal material.
[0037] Furthermore, the assembly between the upper shell 210 and the lower shell 220 adopts a compression assembly method in this utility model;
[0038] like Figure 3-4 As shown, the inner wall of the lower shell 220 is provided with a hook groove 221, and the lower edge of the upper shell 210 is supported by the hook groove 221.
[0039] The hook 222 is provided in the hook groove 221; the lower edge of the upper shell 210 is provided with the hook groove 211;
[0040] The hook 222 is arc-shaped; the slot 211 is an inverted triangle, and the minimum width of the opening of the slot 211 is less than the width of the hook 222; the hook 222 and the slot 211 are interference-fitted.
[0041] During assembly, the heat insulation body 230 is installed into the cavity 201, the upper shell 210 and the lower shell 220 are aligned vertically, and the slot 211 and the hook 222 are also aligned vertically. The hook 222 is pressed into the slot 211 by a pneumatic compressor. Since the minimum width of the opening of the slot 211 is less than the width of the hook 222, the upper shell 210 and the lower shell 220 cannot be separated after pressing.
[0042] like Figure 4 As shown, the card slot 211 is an inverted triangle, and the minimum width of the opening of the card slot 211 refers to... Figure 4 The width of the bottom part of the middle card slot 211.
[0043] Furthermore, the lower part of the lower shell 220 is provided with a first sealing ring 240 that seals with the cup mouth of the cup body 100 to prevent water leakage and air leakage.
[0044] Furthermore, the heat insulation body 230 is foam heat insulation cotton.
[0045] Furthermore, the diameter of the upper shell 210 is larger than the diameter of the cup opening, so that the inner lid 200 cannot fall into the cup body 100.
[0046] The outer cover 300 is placed over the inner cover 200, and a second gap 301 is formed between the outer cover 300 and the inner cover 200, which further reduces the heat transfer from the inner cover 200 to the outer cover 300 and plays a dual role in heat preservation.
[0047] Furthermore, the outer cover 300 is also double-layered, which further enhances its heat insulation and heat preservation functions.
[0048] In one embodiment, the bottom surface of the outer layer 120 partially protrudes 111 towards the bottom surface of the inner layer 110, reducing the contact area between the outer layer 120 and the plane. This makes the thermos cup less prone to scratches when placed, and it can also be placed stably even when the plane has slight unevenness.
[0049] like Figure 2 As shown, the protrusions are arranged in circles and rings.
[0050] In one embodiment, the upper shell 210 is provided with a groove 212 around its periphery for anti-slip purposes.
[0051] In one embodiment, the top of the outer cover 300 is provided with a decorative piece 310, which can be made in the form of a badge and protrudes slightly upward from the end face of the outer cover 300; the outer cover 300 can be used as a teacup when it is turned upside down.
[0052] The thermos cup of this invention has good heat insulation performance, that is, strong heat preservation performance, and the assembly method of the inner lid is simpler.
[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
