Titanium vacuum cup with high-airtightness vacuum thermal insulation cavity

Abstract

The invention discloses a titanium vacuum cup with a high-airtightness vacuum thermal insulation cavity. The titanium vacuum cup comprises a shell, an inner container and the vacuum thermal insulation cavity, wherein the inner container is arranged in the shell, and the vacuum thermal insulation cavity is formed between the shell and the inner container. The titanium vacuum cup is characterized in that each of the inner wall of the shell and the outer wall of the inner container is coated with a nano copper coating. Since the vacuum thermal insulation cavity is coated with the nano copper coatings all around to realize hermetic protection, air is prevented from diffusing into the vacuum thermal insulation cavity through the inner container and the shell, vacuum degree of the vacuum thermal insulation cavity is effectively kept, thermal preservation and thermal insulation performances of the cup are guaranteed against reduction, and thermal preservation time of the vacuum cup is greatly prolonged while durability and quality of the vacuum cup are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of thermos cup structures, and in particular relates to a titanium thermos cup with a highly airtight vacuum heat insulation cavity. Background technique [0002] Compared with conventional stainless steel products, titanium (alloy) thermos cups are more and more popular among consumers because of their lighter and healthier texture, better thermal insulation performance and better corrosion resistance under the same hardness conditions. [0003] Known titanium thermos cups usually have a double-layer structure inside and outside. There is a vacuum insulation chamber between the titanium (alloy) cup liner and the outer shell. The vacuum insulation chamber has high requirements on the vacuum degree. It will greatly affect the heat insulation effect of the whole cup. However, as we all know, titanium (alloy) material itself is a kind of porous material. During long-term use, the outside air can easily ...

Problems solved by technology

[0003] Known titanium thermos cups usually have a double-layer structure inside and outside. There is a vacuum heat insulation cavity between the titanium (alloy) cup liner and the outer shell. The thermal chamber has high requirements on the degree of vacuum, and if it fails to meet the standard, it will greatly affect the heat insulation effect of the entire cup

However, as we all know, titanium (alloy) material itself is a kind of porous material. During long-term use, the outside air can easily diffuse from the cup liner and shell wall to the inside of the vacuum insulation cavity, reducing the internal vacuum degree and gradually losing the vacuum of the cup. good insulation
