A self-cutting type heat preservation pot

Abstract

The invention discloses a self-cut-off type heat preservation cooker including a pot body, a movable plug is tightly attached to the inner side wall of the pot body, the top wall of the movable plug is provided with a fixing port, the bottom wall inside the fixing port is provided with a sealing port, a seal plug is arranged in that seal port, the top end of the sealing plug is provided with a glass cover, a screw thread is arranged on the outer side wall of the bottom of the glass cover, a screw thread engaged with the glass cover is arranged on the inner side wall of the fixing port, a heating plate is arranged in the bottom wall of the pot body, a movable groove is arranged on the inner side wall of one side of the pot body, and a rod hole is arranged on the inner bottom wall of the movable groove. The invention utilizes the heat expansion principle of the air inside the heat preservation cooker to realize the automatic power off of the heating device, the food is heated to a certain temperature, the power is automatically cut off, the food is cooled slightly and automatically energized to heat the heat preservation, no human interference is required, the safety performance of the heat preservation cooker is improved, and the heat preservation time is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of heat preservation pots, in particular to a self-cutting type heat preservation pot. Background technique [0002] The heat preservation pot is a very common equipment in life. It is generally used to keep food warm to maintain its taste, and it is convenient to carry food, which greatly facilitates people's lives. Existing heat preservation pots are generally insulated by vacuum insulation, so that the heat of the food in the pot cannot be dissipated, and it is more convenient to use, but the heat preservation effect is not long enough, and the heat will usually be conducted through the wall of the pot after a period of time , The holding time is not long. There is also electric heating for heat preservation, but because electric heating is difficult to control the heating power, it cannot be adjusted according to the temperature of the internal food, resulting in overheating of the food and affecting th...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the traditional heat preservation pot does not keep warm for a long time and the electric heating type heat preservation pot is not safe enough in the prior art, and proposes a self-cutting type heat preservation pot
