Description

Technical Field

[0001] The utility model relates to the technical field of thermos cups, in particular to a vacuum structure of an intelligent thermos cup. Background Art

[0002] In daily life, whether at home, in the office, or in class, especially for office workers and students, they often use thermos cups to drink water at a suitable temperature. Thermos cups are suitable for use in a variety of places. They are favored by more and more consumers due to their good heat preservation performance, light weight, anti-breakage, hygienic and convenient use, and the demand is gradually increasing.

[0003] The thermos cup is a double-layer structure, and its insulation performance is determined by the vacuum degree of the interlayer. The current manufacturing process of stainless steel thermos cups is: first combine the outer layer and the inner layer of the thermos cup, then weld the upper and lower ports, and finally vacuum seal. The Chinese patent with announcement number CN210095349U provides a vacuum thermos cup, including a cup body, a cup cover body, a base inner cover body and a bottom shell body. The cup cover body and the base inner cover body are respectively arranged at both ends of the cup body, and the bottom shell body is installed at the lower end of the base inner cover body through a bottom shell fixing ring; the base inner cover body is provided with a temperature sensor, a TDS detection module and an ultrasonic water level detection module corresponding to the inner cavity of the cup body, and the temperature sensor, TDS detection module and ultrasonic water level detection module are electrically connected to the PCB functional mainboard arranged between the bottom shell fixing ring and the base inner cover body; a lithium battery and a switch control board are arranged in the bottom shell body, and the lithium battery and the switch control board are electrically connected to the PCB functional mainboard.

[0004] The above-mentioned vacuum insulation cup is essentially just a double-layer vacuum structure for the cup body. There is no vacuum double-layer structure at both ends of the cup body where the cup lid and the inner cover of the base are located, which greatly affects the insulation effect. In addition, whether the electronic components are arranged in the cup lid or the inner cover of the base, there will be greater risks of heat insulation and moisture proofing. Utility Model Content
