Safe long-acting temperature control device

Abstract

The invention particularly relates to a safe long-acting temperature control device. The safe long-acting temperature control device comprises a temperature control device main body with a layered structure, wherein the temperature control device main body comprises a power supply interface, an electric heating layer, a first phase change energy storing layer and a lining thermal insulating layer; an electric heating element connected with the power supply interface is arranged on the electric heating layer, and the electric heating element is used for spontaneous heating under the action of an external power supply; the first phase change energy storing layer covers the upper surface of the electric heating layer and comprises a plurality of heat storing units, the heat storing units are arranged in a manner of being in contact with the electric heating element, phase change materials are arranged in the heat storing units, and the phase change materials are used for storing and releasing heat produced by the electric heating element; and the lining thermal insulating layer covers the upper surface of the first phase change energy storing layer and is used for delaying heat exchange between the first phase change energy storing layer and an external environment. Through the technical scheme, refrigeration and heating can be realized in a power outage state.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a safe and long-term temperature control device. Background technique [0002] In the cold winter, people need to use electric blanket or water heating blanket for heating and insulation. The water heating blanket is a product developed on the basis of electric heating blanket. Its specific structure includes: microcomputer controller, negative ion heat energy water cycle machine and pad body, Compared with electric blankets, its structure is more complicated, its price is higher, and it is easy to generate noise during use. Therefore, it has not formed a large market share. [0003] At present, people are accustomed to using electric blankets as heating equipment in daily life, and have improved them in terms of performance, such as: Chinese patent No. ZL201520251401.4, which discloses an electric blanket, including: electric blanket, switch , timer, the switch is c...

Problems solved by technology

[0004] However, based on the above-mentioned patents, people still need to energize for heating and heat preservation when they are in use. There are safety hazards such as unstable temperature and prone to leakage when energized. It has a wide range of health effects, and can cause adverse reactions such as increased heart rate, increased blood pressure, accelerated breathing, wheezing, and sweating

[0005] Furthermore, the electric blanket can only be used in winter to realize the function of heating and keeping warm. In the hot summer, the electric blanket loses the value of being used by users because it cannot be cooled.
