The working principle of the self-heating evaporation combustion device is as follows:

It works firstly, intelligent combustion controller 1 controls electromagnetic pump 16 by electromagnetic pump control line 18, while by dividing valve The ignition channel that output control line 25 controls fuel feeding distributing valve 17 is the primary outlet opening for connecting igniting oil pipe 2, by fuel tank Liquid alcohol-based fuel in 15 is sent to the top of lower cone 6 wall outer surface of room by igniting oil pipe 2 and to be extended exhibition thin.Then, Intelligent combustion controller 1 controls impulse generator 22 by ignition control line 21 and works, and by ignition electrode 23 to lower cone room 6 Expand the thin liquid alcohol-based fuel of exhibition on wall outer surface to light a fire.After lighting a fire successfully, intelligent combustion controller 1 passes through The ignition channel for dividing valve output control line 25 to control fuel feeding distributing valve 17 is closed, and vaporization channel is the second of connection vaporization oil pipe 3 A outlet is opened, the upper ring pipe 4 that the liquid alcohol-based fuel in fuel tank 15 is sent to self-heating vapourizing unit by vaporizing oil pipe 3 In and be ignited the heat heating vaporization for the first time of process generation, the alcohol-based fuel of vapour-liquid mixed state passes through in upper ring pipe 4 It crosses pipe 5 to enter in inferior pyramidal room 6, the heat for being ignited process generation again in inferior pyramidal room 6 heats vaporization for the second time, guarantees Alcohol-based fuel is completely vaporized to promote to burn.Then, the alcohol-based fuel completely vaporized is from the stomata 7 on 6 side wall of inferior pyramidal room Burning is sprayed, realizes and operates normally.After this, the combustion of the liquid alcohol radical in self-heating vapourizing unit is sent to by vaporizing oil pipe 3 Material is burned the heat that process generates in upper ring pipe 4 and inferior pyramidal room 6 respectively and carries out heating vaporization twice.Small oil mass is defeated Fashionable to avoid being mixed into air in oil pipe, igniting oil pipe 2 and vaporization oil pipe 3 preferentially use stainless steel capillary (interior diameter≤1.5mm), High temperature oxidation resisting anticorrosion, prolongs the service life.

Ignition phase: safe temperature T1 (T1=65~75 DEG C) in liner 9 is set by intelligent combustion controller 1, i.e., Temperature allows ignition procedure to start when being lower than T1.The temperature in liner 9 is obtained by 13 probe 13 of temperature sensor probe, is protected Demonstrate,prove starting ignition program under safety condition: intelligent combustion controller 1 controls impulse generator 22 and works, and ignition electrode 23 is under It bores to expand on 6 outer surface of room and opens up thin liquid alcohol-based fuel progress pulsed discharge preheating, while intelligent combustion controller 1 controls 16 variable frequency work of electromagnetic pump, intelligent combustion controller 1 control fuel feeding distributing valve 17 and open simultaneously ignition channel and vaporization channel, On the one hand fuel needed for controlling appropriate igniting is sent to the upper end of lower cone 6 outer surface of room by igniting oil pipe 2, under the effect of gravity Level of fuel is opened up to thin expansion from top to bottom, is conducive to pulse firing success.When liquid fuel flame temperature rises to setting value When accelerating (T2=160~170 DEG C) firing temperature T2, intelligent combustion controller 1 passes through 19 work of air-blower control line traffic control blower Make, wind oil is actively matched by the air inlet of air hose 20 and accelerates burning, self-heating vapourizing unit is heated rapidly and reaches operating temperature；Separately One side liquid fuel opens conveying small amount of liquids alcohol-based fuel from the vaporization channel of fuel feeding distributing valve 17 and enters self-heating vapour Disguise in the upper ring pipe 4 set, obtains preheating upper ring pipe 4 and inferior pyramidal room 6 rapidly using the heat that ignition process generates In liquid alcohol radical combusting vaporization；When the alcohol-based fuel steam vaporized in self-heating vapourizing unit is from the stomata 7 of inferior pyramidal room 6 It is output to after participating in burning in liner 9, generates more heats, the temperature that temperature sensor probe 13 obtains in liner 9 reaches Setting running temperature T3 (T3=250~280 DEG C).

Operation phase: intelligent combustion controller 1 obtains what the temperature in liner 9 reached by temperature sensor probe 13 The running temperature T3 of setting determines that self-heating vapourizing unit meets the temperature of work, and blower 19 stops working, fuel feeding distributing valve 17 It closes ignition channel, open vaporization channel.According to the call for fire of user, intelligent 1 frequency control electromagnetic pump of combustion controller 16 work, alcohol-based fuel amount needed for precisely obtaining enter self-heating vapourizing unit, and the alcohol-based fuel steam of generation is from inferior pyramidal room 6 Output forms continuous vaporization combustion heating.To obtain better combustion efficiency, the stomata 7 of inferior pyramidal room 6 is arranged to bore downward The outside of shape room 6 is arranged obliquely, i.e., stomata 7 is arranged to form the angle that circumference rotates upwards with horizontal plane, so that alcohol radical fires Material steam forms bottom-up eddy flow in liner 9.Design processing adjusts upper the distance between ring pipe and inferior pyramidal room 6, Guarantee the lower end surface of center line and the intersection point of upper ring pipe 4 of stomata 7 higher than upper ring pipe 4 so that upper ring pipe 4 is corresponding is firing It makes a fire at the internal flame position of flame, the temperature of internal flame can guarantee that being sent into the liquid fuel come is heated vaporization completely, bottom-up After alcohol-based fuel steam eddy flow is adjusted uniformly by necking 10, further it is mixed and burned and is formed outside high temperature in 10 upper end of necking and air Flame.

Alcohol-based fuel steam forms bottom-up eddy flow in liner 9, so that negative pressure is formed at 9 lower part of liner, it is external Air is first inhaled into (blower does not work at this time) from the tail end of blower 19 and enters in the interlayer 11 between outer gallbladder 8 and liner 9, then Entered in liner 9 by the air holes 12 on liner 9 and quickly mix completely burned with alcohol-based fuel steam, meets " the reaction of user It requires fastly ".Cooling effect is played by the external gallbladder 8 of air of negative pressure inspiration and 9 lower part of liner simultaneously.

According to the above working principle, it by prototype test, selects rechargeable battery as intelligent combustion controller 1, supply The power supply of the power consumptions equipment such as oil system, air feed system and ignition system, electromagnetic pump 16, fuel feeding distributing valve 17, impulse generator 22, The accessory that blower 19 selects direct current small-power power consumption low, by burning 1~1.5kg/h of alcohol-based fuel, (calorific value 5000kcal/kg is left It is right) firepower, be fully able to meet the requirement of chafing dish range, the ignition phase time, which is set as 20s-30s, to be operated normally, Ignition phase little power consumption guarantees service time of battery long enough, and being reconfigured small reservoir, (fuel tank size is according to being capable of user's needs Stream time and customize), that is, can be processed into the chafing dish range that user demand " reaction fast, firepower enough, portable " requires.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
