Convenient safety electric heating body heater

Abstract

The convenient and safe electrical heater includes surface cloth layer, inside electric heating layer and rechargeable battery. The electric heating layer has base layer of plastic, heating material of screen printed thin carbon film conducting part of screen printed silver powder. The rechargeable battery is solid lithium-polymer battery with built-in short-circuit protecting circuit. The control circuit board set between the electric heating layer and the battery has temperature probe comprising IC, great power switching transistor and thermistor. The present invention may be produced into waist protecting belt, knee pad or stomach protecting belt. The present invention has the advantages of automatic temperature control, convenient use and safety.

Description

1. Technical field [0001] The invention relates to a medical and health care appliance, in particular to a convenient and safe electric heating body protector. 2. Background technology [0002] The traditional treatment methods for rheumatoid arthritis, cold stomach, and low back pain are hot water bottle sticking, cupping, or electric heating, and they are very effective. However, due to the inconvenience of operation, fewer and fewer people use them. At present, people are more willing to use electric heating body care to treat rheumatoid arthritis, stomach cold and low back pain, because electric heating body care is simple and easy to implement, and the curative effect is also good. The heating element of the early electric heating warm body adopts electric heating wires, and later some adopt (PTC) electric heating belts, such as the technology disclosed in Chinese patent ZL96225167.4; some use carbon fiber heating sheets, such as the technology disclosed in Chinese pate...

Problems solved by technology

The disadvantage of the above technology is that a fixed power supply must be used, and it cannot be used outdoors. On the other hand, it is not convenient to control the temperature, and it is easy to cause fire

Chinese patent ZL 03219439.0 discloses a rechargeable electric heating knee pad, which is mainly composed of a knee pad, a heating element, and an electrical control box. There is a control device in the control box, which can control the temperature to be constant, and can reach the set temperature within a few minutes, which is convenient for external power supply and battery charging, and is used for hyperthermia for knee joint diseases. It is a relatively advanced electric heater at present. Heating body, its disadvantage is that the electrical control box is not intelligent, it needs to be switched manually, it is inconvenient to use, the temperature cannot be automatically controlled, and there is still a fire hazard
