Description

A kind of pin Device for hand warming

Technical field

The utility model relates to electric heating equipment, especially a kind ofly the heat of a thermal source directly can be acted on pin and pin Device for hand warming on hand simultaneously specially.

Background technology

In the winter of cold, people's big mesencephalic centre can be given head and trunk with the automatic priority allocation of limited body heat, and therefore, the heat that four limbs distribute is less.As people during at the office of bending over the desk, study or operating computer, both hands contact ice-cold desktop again because will operate or write, and both feet more will bear the cold air invasion and attack that fall to the face of land, and therefore, both feet and both hands can feel colder.

In fact, as long as pin and hand have warmed up, trunk is because there is the cotton dress protection almost need not warm oneself.

Based on above-mentioned situation, special heating system at pin and hand has appearred on the market in recent years in succession.

For example: electric heating warms up foot washing basin.Be in the chest bottom of a uncovered electric heat source to be installed, both feet are placed on the fence that is arranged at the casing waist and warm oneself.The uncovered structure of this fence type has almost been released all hot-airs, and therefore, power can reach about 300w usually, and power wastage is obvious.Simultaneously, can't take into account the hand heating.

And be specifically designed to the foot-warming vessel that both feet are warmed oneself, though power is little, can not take into account the hand heating too.

And for example: be placed on the desk-top air-heater of small size that desktop is mainly used in learning.Be to brush thermal objects such as heating wire or ceramic PTC heating sheet with blower fan, form hot blast and directly brush hand or desktop.But because blower fan and device disjunctor, after body and the desktop resonance, its noise allows the people be difficult to stand.And hot-air rises after brushing human body at once, is difficult to retaining heat, needs constantly to replenish hot blast.Therefore, though this type of air-heater volume is little, power is up to 450w-1500w, and power wastage is serious.And, also can't take into account foot's heating simultaneously.

In sum, in known products, no matter which kind of heating system all can't directly act on the heat of same thermal source pin and on hand specially.And if allow pin and hand heating simultaneously, then must buy two heating systems, perhaps adopt heating systems such as air-conditioning, the above high-power warmer of 1000w.Therefore, the heating when individual office, study is both inconvenient, wastes surprising again.

Described ground foot warmer is that very thin loam cake is the flat casing of metal material, fills insulation PTC cellular abscess backing in the case.Casing one end air inlet is stayed a perforate after the other end sealing, and blower fan is installed in butt joint and bellows will be carried to the desktop hand warming device by the warmed-up hot-air of PTC cellular abscess backing.

The sealing platen that described desktop hand warming device is a two-sided hollow has covered several and has gone out hot aperture on it, form the wind-heat platen.

Saying further, is a very thin double-deck wind-heat platen, in order to keep smooth indeformable, several support columns is set in the interlayer.The bellows that wind-heat platen one side has open butt joint ground foot warmer to draw up.

Wind-heat platen loam cake can be with wooden boards or plastics manufacturing.Certainly, can also make with metal in order more to be conducive to heat absorption and to conduct heat.

Power supply and each function control switch can be installed on the foot warmer of ground, also can be on the wind-heat platen.When being installed on the wind-heat platen, lead is along guiding on the foot warmer of ground under the bellows.For attractive in appearance, can also adopt high temperature resistant wire in the bellows downwards, arrive thermal source and blower fan respectively.

Energy-conservation in order to embody, on the use state, can design many gears gauge tap.That is: when the power low grade of only opening heating combined equipment for when heating both feet; When hand also needs heating simultaneously, open top grade again, and open blower fan and upwards carry hot-air.Certainly, described each function portion also can open synchronously with a switch.

Described desktop hand warming device can also be the fixedly mouth of pipe of bellows of the shelf formed at a similar Desk lamp feet and flexible pipe, and the mouth of pipe directly brushes hot blast to hand.

Say that further for a preferable outward appearance is arranged, air outlet can be designed to object moulding such as animal, aircraft, rocket, can also be a circular hole, flat round hole or a more flat covering of the fan.
