Novel double-layer vacuum cup

Abstract

The invention discloses a novel double-layer vacuum cup. The novel double-layer vacuum cup comprises a cup body constituted by cup walls, and a cup lid constituted by lid walls; the cup body comprisesan outer cup body (1) with the corresponding cup wall being vacuum in the whole body and an inner cup body (2) with the corresponding cup wall being vacuum in the whole body, and the cup wall constituting the outer cup body is made of a phase-change material; the inner cup body is enveloped in the outer cup body through a lower section of the inner cup body; the cup lid comprises an inner cup lidbody (3), and an outer cup lid body (4) with the corresponding lid wall being vacuum in the whole body; and the inner cup lid body is buckled and fastened on a cup rabbet of the inner cup body, and the outer cup lid body is fastened on an upper section of a cup main body of the inner cup body in an interference mode. Compared with the prior art, an interior and exterior separated structure is adopted, the heat insulation effect is good, and the service life is long.

Description

technical field [0001] The invention relates to the field of thermos cups, in particular to a novel double-layer thermos cup. Background technique [0002] The existing thermostatic cups are all integrated, and other combination methods such as welding are extremely difficult. Due to the immature processing technology, it is not suitable for mass production, and because the temperature of the outer cup body is as high as 500 degrees when the vacuum is pumped, it is inevitable that the phase change material or The chemical structure of other heat-absorbing and exothermic materials such as salt water changes, which reduces its function and life, and the effect is greatly reduced. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide a novel double-layer thermos cup with good thermal insulation effect and long service life. [0004] In order to achieve the above object, the present invention adopts follo...
