Portable and automatic temperature control heating device and method

Abstract

The invention discloses a portable and automatic temperature control heating device and method. The portable and automatic temperature control heating device comprises a shell, a rechargeable battery and heating units, and the shell is in a disc shape and is equally divided by a plane passing through the axis of the shell into four fan-shaped unit shells; the surface, spliced with the adjacent unit shells, of the unit shells are spliced lateral walls, the two spliced lateral walls of one same unit shell are respectively provided with the input end and the output end, and the input end of any unit shell corresponds to the output end of the adjacent unit shell; the spliced position of any two adjacent unit shells is further provided with a locking piece; the rechargeable battery is installed in one unit shell, and the heating units are installed in the remaining unit shells. When the locking piece is unlocked, as the adjacent unit shells can be detached, and the detached unit shells are only one fourth of the whole, the unit shells can be overlapped together to be plugged into a schoolbag or a hand bag, or the unit shells can be packaged in a small bag to be carried, insufficient width and insufficient length are not required to be considered, and the portable and automatic temperature control heating device accordingly has the advantage of being convenient to carry.

Description

technical field [0001] The invention relates to a heating device, in particular to a portable automatic temperature-controlled heating device and a method thereof. Background technique [0002] In the past, in the cold winter, most people kept warm through hot water bags. With the advancement of science and technology, in order to improve living standards, electric hand warmers such as electric warmers have been developed and put into the market, and such electric hand warmers have received great welcome from the common people in the market. However, the current electric hand warmers on the market are designed to be small and compact in order to be easy to hold. In order to be compact, it needs to sacrifice the capacity of the battery, which also results in a very small battery life of the electric hand warmer. Good for takeaway.

However, the current electric hand warmers on the market are designed to be small and compact in order to be easy to hold. In order to be compact, it needs to sacrifice the capacity of the battery, which also results in a very small battery life of the electric hand warmer. Good for takeaway

[0003] If in order to improve the battery life of the electric heating hand warmer, the conventional method is to improve it by adding batteries, but this improvement will cause the volume of the electric heating hand warmer to become very large, which invisibly increases the difficulty of carrying the electric heating hand warmer. Especially if you want to take it out, ordinary schoolbags or handbags cannot directly hold the entire electric hand warmer due to the limitation of width or length, so this improvement has led to the disadvantage of inconvenient portability
