Embodiment Construction

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0023] like figure 1 , figure 2 and image 3 As shown, the thermos cup includes an outer cup body 1 and an inner container body 2. Both the outer cup body 1 and the inner container body 2 are titanium metal parts. The vacuum chamber 3 on the periphery of the inner tank body 2, the outer cup body 1 is sleeved outside the inner tank body 2, the cup mouths of the outer cup body 1 and the inner tank body 2 are in the same direction, and the inner tank body 2 and the outer cup body 1 are in the same direction. The ring seal is fixed at the mouth of the cup. It is relatively easy for both the inner tank body 2 and the outer cup body 1 to be sealed and fixed annularly at the mouth of the cup, so that the volume of the vacuum chamber 3 is larger.

Abstract

The invention provides a vacuumizing structure for a titanium vacuum flask and belongs to the technical field of vacuum flasks. The vacuumizing structure solves the technical problem that due to the fact that the firmness of an existing solid glass cement seal is poor, the service life of the vacuum flask is influenced. The vacuum flask comprises an outer flask body and an inner container. The vacuumizing structure comprises a titanium metal nut and stainless steel screws. The nut is fixedly welded to the bottom of the outer flask body. The nut is provided with screw holes penetrating through the two end faces of the nut. The bottom face of the outer flask body is provided with through holes communicated with a vacuum cavity. The through holes are communicated with the screw holes. The screws are arranged in the screw holes in the outer flask body. The screws are provided with air outlet holes communicated with the screw holes. The air outlet holes of the screws are provided with solid glass cement seals in a fusion welding mode, wherein the solid glass cement seals can seal the air outlet holes. According to the vacuumizing structure, the titanium nut is welded and fixed to the titanium outer flask body, and then the stainless steel screws and the titanium nut are connected in a screwed mode so that the nut and the outer flask body can be connected firmly, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation cups, and relates to a titanium metal vacuum thermal insulation cup, in particular to a vacuuming structure of the titanium metal vacuum thermal insulation cup. Background technique [0002] The thermos cup is generally a water container made of ceramic or stainless steel plus a vacuum layer. The top has a cover and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of liquids such as water inside to achieve the purpose of heat preservation. There are many layers in the thermos cup. Its interlayer is generally vacuumed to prevent heat conduction, and then plated with silver, which can prevent heat radiation. Some cups have corks on top 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 CN2...
