Abstract

The utility model provides a micro-heater which is a heating device applied to outdoor use and a family. The structure is that a heat resistant fibre core is arranged in a metal tube of phi 3-5 mm. The lower end of the metal tube is inserted into a fuel box. The upper end of the metal tube is connected with a bowl-shaped combust head on whose circumference 6-8 apertures are drilled. The fuel is absorbed upwards by a tube core. The fuel is gasified at the upper end and is ejected from an aperture to combust. The flame is stable and even. The combust is complete. The ignition can be implemented by only one piece of match. The structure is simple. The alcohol is mainly used as the fuel.

Description

Micro-heater

The invention belongs to and live with small-sized heater one class.

According to the understanding of applicant to prior art, not finding has similar part with the present invention.

The present invention is mainly used in family, journey, open-air when not having other firing equipments to the usefulness of the heating of food, beverage etc.The microheater spare that uses in view of present production is as alcohol heater, hand warmer, and the former uses formality more numerous, and inconvenience is carried in fuel and body of heater packing, and it is steadily wayward that flame is owed, and latter's heating power is less, and Catalytic Layer is inefficacy shortcoming such as be difficult for igniting easily.The present invention has burning steadily, and burning fully, and is safe in utilization, ignites easily advantages of simple structure and simple, the thermal source of providing convenience for places such as family, journey, fields.

Structure chart of this microheater such as accompanying drawing (1).The bottom is metal fuel box (1), and fuel cartridge diameter can be φ 50～90mm as required.It is that the metal tube (2) of φ 3～5mm directly inserts the fuel cassette bottom that there is a diameter at fuel cassette middle part, with screw thread or other structures and fuel cassette sealed attachment.Metal tube suitable for reading with fuel cassette at a distance of 20～35mm.The metal tube combustion head (3) that is connected with suitable for reading.Combustion head is bowl-shape by the metal sheet compacting, is drilled with 6～8 φ 0.2～0.3mm apertures all around.Combustion head top is that the lid (4) that is pressed into of metal sheet is with combustion head cap seal suitable for reading.(5) add inlet for fuel.The bottom tube core of metal tube (2) is filled with cotton fiber with draws fuel, and top is filled with heat resistance fiber.When burning several seconds with match or other flame in the combustion head bottom, fuel is promptly vaporized from port ejection burning, is the colourless flame of petal-shaped (6).The a part of heat in burning back imports metal tube into makes the continuous vaporization combustion of fuel that flame is maintained.When certain reason makes the burning aggravation, when the fired vapour amount increases,, burn and can too not aggravate owing to be subjected to the restriction of metal die to fuel delivery, just evaporating area moves down slightly, and vice versa.So it is flame-out that burning steadily, is difficult for.This microheater is mainly made fuel with alcohol or other fuel.Alcohol content can be used greater than 80%.

This microheater can be adorned an integral body with baby's glass milk bottle And, makes the milk bottle warmer, can be heated to 50 ℃ in 10 minutes in the winter time, the usefulness of the infant feeding of being convenient to go out.Heating once only needs alcohol 3～5mL accompanying drawing (2).

This microheater can be dressed up an integral body with metal cup, as the usefulness of field, journey, hook fish fan's the hot tea of cooking on a small quantity.Accompanying drawing (3)

This microheater can increase the usefulness of suitable support as soup dish insulation heating between feast.

Claims (1)

1. Microheater is characterized in that the fuel cassette middle part connects a bottom and is filled with the metal tube that cotton fiber top is filled with heat resistance fiber, and the pipe upper end connects bowl-shape combustion head, is drilled with the hole of 6～8 φ 0.2-φ 0.3mm around the combustion head.
