Electric heating thermos bottle with safety structure

Abstract

The invention discloses an electric heating thermos bottle with a safety structure. The thermos bottle comprises a handle, a surface cover, a middle cover, a liner, a shell and a base, wherein a snap ring is arranged on the outer wall of the liner in a sliding and sleeving mode; and the handle is connected to the snap ring by virtue of middle cover pull plates; rotating shafts are respectively arranged at the inner parts of the two ends of the handle, and convex parts are arranged at the upper parts of the rotating shafts; an upper end through hole is formed in each middle cover pull plate; and the middle cover pull plates are arranged on the rotating shafts of the handle in a sleeving manner by virtue of the upper end through holes and are limited in the convex parts. A non-stop inserting pin is arranged at the lower end of each middle cover pull plate; the snap ring is provided with inserting holes corresponding to the non-stop inserting pins; and the non-stop inserting pins are inserted into the corresponding inserting holes. Through holes are formed in two sides of the middle cover; avoiding parts are arranged at the lower ends of the through holes; and the handle is fixedly arranged on the middle cover by virtue of buckling connection of the rotating shafts and the through holes. The thermos bottle disclosed by the invention has the characteristics of being simple and reasonable in structure, reliable in performance, firm in connection, long in service life, beautiful and practical.

Description

technical field [0001] The invention relates to an electric heating water bottle, in particular to an electric heating water bottle with a safety structure. Background technique [0002] Electric heating water bottles on the market are of a great variety, and are widely used, bringing convenience to people's drinking water. Then, how to make users safer in the daily use of electric heating water bottles is also a topic worth studying by technicians. as in the accompanying drawings figure 1 and figure 2 As shown, the traditional boiling water bottle is connected with the buckle holes provided at the two ends of the middle layer cover 3' through the handle, so as to provide the user with a bottle of boiling water; after the boiling water bottle of this structure is used for a long time, the plastic will start to slow down. With slow aging, the mechanical strength and toughness will be reduced. When the plastic parts are seriously aged, the strength cannot bear the weight o...

Problems solved by technology

as in the accompanying drawings figure 1 and figure 2 As shown, the traditional boiling water bottle is connected with the buckle holes provided at the two ends of the middle layer cover 3' through the handle, so as to provide the user with a bottle of boiling water; after the boiling water bottle of this structure is used for a long time, the plastic will start to slow down. With slow aging, the mechanical strength and toughness will be reduced. When the plastic parts are seriously aged, the strength cannot bear the weight of water, and it may be lifted after the water bottle is filled with water during use, and the middle cover 3' is connected to the inner tank. location, see figure 2 In the place B shown, there is aging and cracking phenomenon. After the middle layer cover 3' is cracked, the inner tank falls off and the boiling water splashes out and scalds the user, which poses a safety hazard to the user.
