Abstract

The utility model relates to an electronic-ignition vaporizing alcohol stove, belonging to the field of domestic igniting utensils. The electronic-ignition gasifying alcohol stove is composed of a fuel tank, an electronic ignition, a pressure device and a combustion controlling part. The electronic-ignition gasifying alcohol stove injects a proper amount of pressure into the fuel tank through a pressure air pump to press alcohol liquids into a vaporizing tube and to ignite and heat the alcohol liquids and steams in a preheating disk and a vaporizing chamber through the electronic ignition to achieve the vaporizing and combusting purpose. The utility model is particularly suitable for chafing dishes and domestic life to use as a cooking stove.

Description

Electronic-ignition gasifying alcohol stove

The utility model is that a kind of pulsed electron ignition gasification alcohol heater (being designated hereinafter simply as gasification burner) national uses fuel apparatus field.

Alcohol has entered huge numbers of families as a kind of safety, health, convenient and practical fuel for chafing dish.The patent No.: 92235129.5 " the energy-conservation vaporization alcohol heater of adding pressure type garden dish type ", have good looking appearance, safe and convenient to use, vaporization combustion is abundant, advantage such as firepower regulated at will, odorlessness, no flue dust, service time are long.Be subjected to users' welcome deeply.The weak point of this product is must adopt the manual firing before the burning, has a lot of inconvenient and troubles.The utility model solved above-mentioned weak point, on the constant substantially situation of this product structure, in the gasification burner bottom one ignition has been installed, made it in use, more convenient safe, practical, made on the original product class, advanced more on performance.Be particularly suitable for the chafing dish stove of hotel, restaurant and family.

The purpose of this utility model is a kind of safe ready practicality to be provided, can be the energy-saving gasfied stove tool of fuel with electronic ignition, with alcohol or similar alcohol for society.

Be illustrated referring now to accompanying drawing:

Fig. 1 is the agent structure cutaway view of this product

Fig. 2 is the structure vertical view of this product

Gasification burner divides three parts promptly: fuel tank, pressurization electronic ignition device, control vaporization combustion.Its structure and use principle are:

Matrix technology is adopted in fuel tank 3 bottoms that are the garden dish type from accompanying drawing as can be seen, an ignition is equipped with in the inside, one woven hose joint 5 also is installed in the bottom, woven hose 6 is connected with fuel tank, one is connected with a generating tube 2 on woven hose, this generating tube other end is connected with the needle-valve 12 that is in the fuel tank position, see Fig. 1, this needle-valve has extended upwardly a bending jet pipe 11, the aperture of the nozzle 10 of this jet pipe is a 0.8-2 millimeter scope, this nozzle takes over 9 to the vaporizer of the vaporizer 8 that is in fuel tank disk center position, is connected with a preheating dish 7 below this vaporizer 8, above be connected with generating tube 2.Locate to be equipped with an electronic ignition porcelain knob head around the preheating dish, the igniting pin 18 on this porcelain knob is the bifurcation font, the burner port direction of a first sensing vaporizer, and the other end is then pointed to downwards in the preheating dish.One hand air pump 12 and the case lid 1 that gas can be charged in the case also is housed, upper frame 17 on fuel tank 3.For the purpose of attractive in appearance, a switch base 13 also is equipped with at the needle-valve place on the week of fuel garden, and leg 4 is installed below.See Fig. 1.

Gasification burner principle and operation step in use poly-ly is:

Case lid is opened, give and add alcohol (can only adorn about 4/5) in the fuel tank, fasten case lid 1, close the pass of needle-valve 12 and open handle 14, back and forth the handle of injection force (forcing) pump 15 is 16 about 20 times, at this moment produced a point pressure in the fuel tank 3, opening handle 14 nozzles after the combustion begins to eject alcohol liquid to vaporizer 8 and fire dish 7, when treating that fire dish has had a spot of alcohol, should close handle 14, needle-valve 12 is closed, nozzle 10 stops atomizing of liquids, see accompanying drawing, at this moment press ignition button 20,18 beginnings of igniting pin are hit the electricity sparking towards the alcohol in the preheating dish, alcohol is lighted preheating in will coiling.About 15-30 is after second, the handle 14(that opens needle-valve 12 again is at this moment because generating tube 2 has produced certain temperature, alcohol is vaporized at in-tube evaporation, produced certain pressure), what nozzle 10 sprayed has been not liquid just, but fuel gas, in the gas that ejects injects the pipe of adapter 9, because the guiding of taking over is along the direction in vaporizer inwall garden, sees Fig. 2, the fuel gas that injection is come in is evenly distributed in the vaporizer 8, discharge and extraneous air mixed combustion from the burner port of vaporizer then, heated simultaneously the alcohol in the superincumbent generating tube 2 again, made it uninterrupted vaporization, with supply nozzle.When gasification burner extinguishes the back and generating tube 2 when being in high temperature and need lighting sometimes, at this moment only need needle-valve is opened, fuel gas is outwards flowed out.Press igniter button 20, igniting pin 18 make progress can this be lighted gas.Owing to burning position with on fuel, from tank inner wall certain space is arranged again, therefore prevented the conduction of heat.Used 5 hours by reality, the temperature of fuel tank is no more than 70 ℃, and air pressure inside is only below 0.05MPa, and the design pressure of fuel tank 3 is more than 0.9MPa, thereby safe and reliable when using.

The utility model is because outward appearance is garden shape, and whole height is low, and is attractive in fashion, and operating grip is concentrated, after electronic ignition was installed, safe and convenient to use, firepower was big, again can regulated at will, vaporization is abundant, good energy-conserving effect, and use cost and oil gas are suitable, but are better than oil gas in others.The chafing dish that is particularly suitable on the dining table uses, and higher use value is arranged.
