Description

Portable Heaters {PORTABLE WARMER}

The present invention relates to a portable heating device using a built-in power supply unit for use as a power source, in particular, separated from the power supply unit, portable heating that realizes the function of the heater while protecting each terminal, switch, etc. provided in the power supply unit Relates to a device.

In addition, the term 'portable heating device' used in the present invention is a warmer used to raise the temperature higher than the ambient temperature in which the portable heating device is mounted. It's not limited to the ability to warm hands.

In addition, the term 'power supply unit' used in the present invention, means means for supplying electrical energy, means a primary battery, a rechargeable secondary battery or a portable charger for charging the secondary battery as a general consumable battery. .

Generally, a portable heating device (for example, a portable heating device or a pocket stove) is a cold protection device that generates heat for the purpose of preventing the cold in winter. It is very useful for those who want to enjoy in the cold winter.

Such a portable heating device may be divided into powder and liquid. The most common of the contents are powdered powder, salt, and activated carbon. At this time, salt and activated carbon act as a catalyst to speed up the oxidation of earlobe powder. Oxygen is used when the powder is oxidized, so the outer bag, such as a plastic bag, is removed and oxygen begins to warm up. Disadvantages are only one-time because the powder is not reduced once oxidized. In addition, the contents are made of liquid using the property of sodium acetate to give out the heat when it is stimulated to crystallize. Put the sodium acetate and the metal button together in a plastic bag and 'tick' the metal button to heat the contents harden . When the contents are hardened, they are put in water, boiled, and then used again.

In addition, as a portable heating device, various products have been developed, such as a heating device having a heating coil installed therein, or a portable heating device in which a platinum catalyst and a fuel used in the ignition port are applied to lighter oil. The portable heating device has been troublesome in use such as fuel injection or fire as it generates heat by igniting fuel such as lighter oil, etc. In order to solve the problem, a portable heating device that generates heat by supplying power to heating wire has recently been sold. It is becoming.

In particular, recently, a portable heating device that uses a lithium ion secondary battery employed in a mobile communication terminal to increase the use time has also been sold. That is, a product having a function of a portable heating device while charging a rechargeable electric portable heating device or a portable electronic device has been developed.

The electric rechargeable portable heating device is an eco-friendly product that can be reused using its own internal battery and a rechargeable battery, and it is inconvenient to dissolve the contents in hot water and fuel injection generated when using a product such as a lighter oil / gas portable portable heating device. It has the advantage of eliminating the hassle and oil smell.

However, the electric charge portable heating device as described above is made of a plastic or metal cover. Therefore, when used as a portable heating device, the user's hand is in direct contact with the cover, there is a problem that the operation button and the like of the portable heating device is contaminated by the sweat secretion. That is, although each operation button of the portable heating device is waterproofed, such function of waterproofing is deteriorated due to frequent use, and moisture and salt of sweat infiltrates into the operation button and the corrosion of the metal member and portable heating device. It caused a short circuit.

In addition, in the case of a portable heating device that can be used as a charger, the user's hand is in direct contact with the cover of the charger, so that there is a problem that discharge occurs due to malfunction of the switch terminal for the charger due to friction with the terminal of the charger.

On the other hand, when the charger is used in summer when the portable heating device is not used, the portable heating device has a function of the portable heating device, so it must be used while carrying it in a heavy and bulky state. If there is a short circuit in the circuit, there is a problem that the entire charger cannot be used.

In addition, in the case of the conventional rechargeable portable heating device, there is a fatal contradiction in which internally generated heat is intentionally and continuously generated even though heat generated internally is rapidly dissipated to the outside due to the characteristics of electronic products.

In addition, in the case of the rechargeable portable heating device, since the cover portion is formed of plastic or metal, there is a problem that the user's touch is not so good.

In the case of the rechargeable portable heating device, even if a heat insulating material is provided inside the charger, when frequently used by the heating of the charger itself and the heating for the portable heating device, the thermal insulation function is deteriorated. There was also a problem that the provided electrical circuit is broken or malfunctions.

In addition, in the case of the rechargeable portable heating device capable of charging the portable electronic device, since the portable heating device is generally used in a user's clothes bag, the power supply port for supplying power to the portable electronic device is damaged by contaminants in the pocket. There was a problem.

On the other hand, when a portable electronic device using a battery, such as a mobile phone or a digital camera, is exposed to cold for a long time in winter, the battery is rapidly discharged, so that the user can maintain the temperature of the portable electronic device at a constant state. Was needed.

In addition, when playing baseball or golf in the winter, when the temperature of the ball itself decreases, the flying distance is reduced. have.

In order to solve this problem, when the portable electronic device or the ball is inserted into a pocket provided with a hand stove, the portable heating device or the portable electronic device may be damaged by friction between the portable heating device and the portable electronic device or the ball.
