Problems solved by technology

[0002] Existing heating equipment is generally heated by turning on the mains electricity to make the resistance wire heat. This kind of equipment has a large volume and must be connected to the mains electricity when in use. Therefore, in addition to being inconvenient to carry, because of its high heating temperature, Poor controllability, there is a big safety hazard, especially not suitable for the elderly and children
Among the existing portable heating equipment, the hot water bag is undoubtedly the most common. Its principle is to heat the water in the bag with electricity for a certain period of time, and then use the water as a heat source to release heat. This heating method has a high initial temperature and a low later stage temperature. It cannot be controlled and adjusted, and the exothermic process cannot be stopped before the heat is released, causing excess heat to be wasted; in addition, the heating efficiency of the resistance wire itself is low, so this method is not energy-saving and environmentally friendly

Abstract

The invention relates to the technical field of portable warming equipment, in particular to a portable warmer. The warmer is additionally provided with a microprocessor and a temperature sensor, wherein the microprocessor comprises a fuzzy heating control unit, a charging control unit and a battery protection unit which are respectively used for controlling the heating temperature of a heating element, selecting a charging mode of a lithium battery and protecting the battery in the processes of charging and discharging the battery. The invention has the advantages of compact product structure, small volume, light weight (lighter than 80g), convenient carrying, short charging time (the warmer can be fully charged within 2 hours), long heating time (the warmer can be continuously used for 3-7 hours according to the condition of environment temperature after the battery is fully charged), free control of warming time, and the like.

Description

Technical field: [0001] The invention relates to the technical field of portable heating equipment, in particular to a portable heater. Background technique: [0002] Existing heating equipment is generally heated by turning on the mains electricity to make the resistance wire heat. This kind of equipment has a large volume and must be connected to the mains electricity when in use. Therefore, in addition to being inconvenient to carry, because of its high heating temperature, The controllability is poor, and there is a large potential safety hazard, especially not suitable for the elderly and children. Among the existing portable heating equipment, the hot water bag is undoubtedly the most common. Its principle is to heat the water in the bag for a certain period of time, and then use the water as a heat source to release heat. This heating method has a high initial temperature and a low later stage temperature. It cannot be controlled and adjusted, and the exothermic proc...
