Embodiment Construction
[0023] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0024] Such as figure 1 with figure 2 As shown, the thermos cup includes an outer cup body 1 and an inner container body 2. The outer cup body 1 and the inner container body 2 can be titanium metal parts. Titanium metal has the advantages of light weight and high strength, but the gap between glass glue and titanium metal The welding is not firm and easy to detach. This thermos cup overcomes the defect that the fusion between the glass glue and titanium metal is not firm and easy to detach through the concave cavity 4 and the necking part 7, and improves the firmness of the solid glass glue seal 8, which has great advantages. Big technological breakthrough. Of course, in order to further improve the firmness of the soli...

The invention provides a vacuum pumping structure of a metal vacuum cup and belongs to the technical field of vacuum cups. The technical problem that an existing vacuum cup opening sealing process is complicated is solved. The vacuum cup comprises an outer cup body and an inner container body, wherein a vacuum cavity capable of wrapping the periphery of the inner container body is formed between the outer wall of the inner container body and the inner wall of the outer cup body. The vacuum pumping structure comprises a cavity located between the bottom of the outer cup body and the bottom of the inner container body, wherein the bottom of the outer cup body is sunken towards the side of the inner container body to form the cavity, a pumping hole communicated with a vacuum cavity is formed in the inner end portion of the cavity, a feeding port communicated with the outside is formed in the outer end portion of the cavity, the cavity body opening of the cavity radially and inwards contracts, a necking portion is formed at the position of the feeding port, the cavity is full of solid glass cement for opening sealing, and the solid glass cement seals the opening and the pumping hole. The bottom of the outer cup body is sunken towards the side of the inner container body to form the cavity of the vacuum cup, a material is taken from the outer cup body without additional parts, and the vacuum pumping structure is simple and low in cost.
Description
technical field [0001] The invention belongs to the technical field of thermos cups, and relates to a titanium metal vacuum thermos cup, in particular to a vacuum pumping structure of a metal vacuum thermos cup. Background technique [0002] The thermos cup is generally a water container made of ceramics or stainless steel with a vacuum layer. It has a cover on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside to achieve the purpose of heat preservation. There are many layers inside the thermos cup, and its interlayer is generally vacuum to prevent heat conduction, and then plated with silver to prevent heat radiation. Some cup lids have corks on them, also to prevent heat conduction. [0003] In order to improve the quality of drinking water, some manufacturers have produced titanium thermos cups, such as a titanium thermos cup and its manufacturing method disclosed in patent CN201310315341.3. C...
