Abstract
The utility model relates to the design field of hand warmers, in particular to a portable electric heating hand warmer which comprises a casing, a radiation fin, a heating membrane, a circuit board and a battery. The circuit board and the battery are arranged in the casing, the radiation fin is installed on the top surface of the casing, the heating membrane is arranged in a gap between the casing and the radiation fin, the battery and the heating membrane are simultaneously connected with the circuit board electrically, and the circuit board is further electrically connected a temperature sensing controller and a switch for controlling connection and disconnection of a power supply. By means of the technical scheme, the portable electric heating hand warmer is safe and long in service life.
Description
Technical field
This utility model relates to the hand warmer design field, relates in particular to a kind of portable electric heating hand warmer.
Background technology
Hand warmer is the automatic heating health care articles for use of utilization physics and principles of chemistry development.This product is given birth to heat automatically with it, and is interesting, and novel special advantages such as practicality is well received---and hand warmer has automatic heating, multiple function such as health-care physiotherapeutic.
PET metal heating film is a kind of flexible, planar heating, and the thermal efficiency is high.Electric radiant Heating Film is planar exothermic material, forms thermal conductive surface to greatest extent with heated object.This mode of heating conductive performance is good, does not have naked light to produce, and heat loss is very little.Therefore, with the electric heating appliance that Electric radiant Heating Film is processed, the thermal efficiency is quite high, generally all about 95%.
Hand warmer on the market is warm handbag again now, and can be divided into two kinds: a kind of is disposable; The plastic bag the inside is some powder such as iron powder, carbon dust, salt etc.; As long as tear packaging bag when using; Powder and the airborne oxygen haptoreaction of the inside are promptly generated heat, and only with usefulness once, be not wait in 8～14 hours service time; Another kind can use repeatedly, and the plastic bag of sealing (PVC) has some liquid and a small circular sheet metal, as long as pull this sheet metal, the material of the inside promptly can transfer crystal state to from liquid condition, and this physical process is heating just.
Also have a kind of soft liquid electric heating hand warmer to use new technique energy storage exothermic mixture in addition, heat temperature raising is rapid.Disposable water filling, the permanent use, unique explosion-proof non-ironing device, temperature control protection; Long service life; Be incubated advantages such as lasting.Operation principle is improved on the basis of solid electric pancake, adopts the electric pole type heating means, high-quality temperature control and the insurance of thermal cut-off double temperature control.
But mostly existing hand warmer inside is liquid; Damaged easily when carrying or using, service life is shorter, the many healths that influence easily of leak of liquid that hand warmer is inner; There is potential threat; And the hand warmer that uses heating wire is usually scalded user easily easily because the heating wire surface temperature is too high, and safety is lower.
Summary of the invention
The goal of the invention of this utility model is to provide a kind of longer service life, uses safer portable electric heating hand warmer.
In order to realize the foregoing invention purpose, the technical scheme of this utility model is:
A kind of portable electric heating hand warmer comprises housing, fin, heating diaphragm, wiring board, battery; Said wiring board, battery are arranged on enclosure interior simultaneously, and fin is installed in the end face of said housing, and the slit between housing and fin is provided with the heating diaphragm; Said battery, heating diaphragm be the electrical interconnection plate simultaneously; On said wiring board, also be electrically connected with the switch of temperature sensing controller and control on/off.
Optional, described heating diaphragm is a PET metal heating film.
This utility model utilizes battery that power supply is provided through the heating diaphragm is set between housing and fin, the diaphragm-operated heating power of wiring board control heating, and the diaphragm-operated heat that generates heat distributes through fin, and this utility model uses safer, longer service life.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to this utility model, constitutes the application's a part, does not constitute the improper qualification to this utility model, in the accompanying drawings:
A kind of cutaway view that Fig. 1 provides for this utility model embodiment 1.
The specific embodiment
