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 thermos cups, and relates to a titanium metal vacuum thermos cup, in particular to a vacuum pumping structure of a titanium 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 CN201310315...
