Description

A kind of novel electric hand warmer

Technical field

This utility model relates to a kind of hand warmer, particularly a kind of novel electric hand warmer that internal battery is arranged and can realize two-sided heating.

Background technology

At present, the hand warmer on the market, its structure is in calandria, to place a heating plate mostly, after its charging heating, realizes warming oneself and uses.In use, there are a lot of problems in this hand warmer; For example: 1, have only a hot plate, heating-up temperature is difficult to control, and is very hot when often bringing into use; Be difficult to be held in the hand use, simultaneous temperature can reduce again very soon, and can not heat at any time as required; Can only after charging, generate heat at once, use inconvenience, be difficult for going out to carry; 2, function singleness can only realize heating function, has no additional function; 3, strict to the power supply input, can only use the 220V commercial power socket to charge, can't charge through the USB mouth of computer.Simultaneously, the electronic product of carrying now, for example MP3, MP4, PSP, mobile phone etc. are more and more; In a single day these digital products do not have; Can't use, even can influence the orthobiosis of carrier, very inconvenient; And these digital products are provided with the USB charge function mostly, can utilize portable power source to charge; Even if 4 have the hand warmer that similarly adds battery, but volume is big, thicker can only be single face heat conduction, and thickness is 2 times of this product.

The utility model content

To the deficiency of prior art, this utility model provides a kind of novel electric hand warmer.

To achieve these goals, the measure taked of this utility model:

A kind of multifunction electric hand warmer comprises shell body, and inner housing is provided with button and display lamp also has socket, and affiliated inner shell in-body power source can be through the socket discharge;

Described display lamp is provided with the display lamp light transmission piece;

Described button is the key switch with third gear control position;

Described heating sheet is the exothermal infrared film of low-voltage.

The beneficial effect of this utility model is: pattern is elegant in appearance, and thickness is ultra-thin, is easy to make; Two heatings, easy to use; The power supply of employing internal battery can be opened power supplying and heating at any time according to user's needs, need not be subject to the restriction of commercial power socket; Can utilize USB charging or 5V power source charges; Hommization more, and can make portable power source for mobile phone or other digital products at same spigot and use, more practical, convenient; With the worry of a big string charger, the utilization rate of product will improve greatly when solution is gone out; Diverse in function, it is multi-functional to integrate warm hands, portable power source etc.; Adopt the exothermal infrared film heating of low-voltage, use lithium battery power supply, service life is of a specified duration, uses through actual, can realize recycling more than 500 times; Simple for structure rationally etc.

The specific embodiment

A kind of multifunction electric hand warmer comprises shell body 2, and inner housing 8 is provided with button 7 and also has socket c with display lamp b, and power supply can be through socket c discharge in the affiliated inner housing 8; Described display lamp b is provided with the display lamp light transmission piece; Described button 7 is the key switch with third gear control position; Described heating sheet is the exothermal infrared film of low-voltage.

For the ease of carrying and using, said shell body 2 is preferably rectangle shape, and this structure is fit to hold.Battery 3 is installed in the inner housing 8, the battery 3 preferred lithium batteries that adopt, lithium battery is of a specified duration service life, can use repeatedly, can reach more than 500 times to recycle, and has improved the service life of this utility model greatly.Heating sheet 4 is set on inner housing 8 outsides, and heater is exactly a shell body 2, and said shell body 2 and contact skin realize the heating service function.Because about two layers of inner housing 8 minutes is just isolated battery 3 and heating sheet 4, the high temperature that the sheet 4 that can prevent to generate heat sends damages battery 3.The said heating sheet 4 preferred exothermal infrared films of low-voltage that adopt.The heating sheet can be realized heating function under the power supply of battery 3.The socket c that can realize charging with reverse charge is set on inner housing 8; The charge and discharge of socket c are realized by the difference of connecting line; Charge and discharge is discerned and controlled to IC chip on the circuit board 5 automatically, thereby realize the switching of product charging and portable power source function.This utility model can utilize USB charging or 5V power source charges; Hommization more, and socket c can do the portable power source use to mobile phone or other digital products, more practicality, convenient; Carry a large amount of chargers and digital product when solution is gone out and do not have electric worry suddenly, the utilization rate of product is high.Switch 7 is set on inner housing 8, mounting circuit boards 5 in the inner housing 8, circuit board 5 is connected with battery 3, heating sheet 4 respectively.Key switch a, display lamp b, socket c are on wiring board 5.

The pairing hand warmer state of three gears of this key switch is: 1., close hand warmer, promptly febrile state not moves the reserve battery function; 2, the two-sided heated condition of hand warmer; 3, open mobile stand-by power supply function.There is a display lamp light penetrating object inside casing upper end; With on the wiring board 5 status indicator lamp b being set; Can be through the conversion of the switching of status indicator lamp b light, color; Reflection this utility model current state, as: charged state, reverse charge state, closed condition, opening, filament saturation state etc.

This utility model is further characterized in that: this utility model integrates warming, portable power source, multi-functional, and volume is very little, ultra-thinly greatly facilitates the daily use of user.

In above-mentioned each embodiment, the display lamp light transmission piece preferably is set on status indicator lamp b, status indicator lamp b cooperates the display lamp light transmission piece to use, and can more clearly show current user mode.

Those skilled in the art's simple change and replacement all are within the protection domain of this utility model.
