Other parts not described above, like the first embodiment, are not repeated.
Third embodiment
Referring to fig. 3, the main difference of the alcohol burner from the first embodiment is that the fuel feeding device 1 includes a third liquid pump 11 and a liquid reservoir 12, an output end of the third liquid pump 11 is connected to an inlet of the liquid reservoir 12 near a high water level through a pipeline, and an outlet of the liquid reservoir 12 near a low water level is connected to input ends of a first liquid pump 41 and a second liquid pump 42 through pipelines. The liquid storage device 12 is in a tank shape or a coil pipe shape, and a water level detection device 13 is arranged in the liquid storage device.
The first liquid pump 41 and the second liquid pump 42 pump fuel from a low position of the liquid storage 12 (i.e. a position close to the bottom of the liquid storage 12) and the liquid storage 12 can store a certain amount of fuel, and the household alcohol combustion stove can generally store 20-50ml of fuel, so that the liquid storage 12 does not need to be too large in volume and can be installed in the existing alcohol combustion stove without changing the substantial structure. When the alcohol burner is used, the first liquid pump 41, the second liquid pump 42, the vaporizing ring 2, the straight nozzle 3, and the fuel atomizing nozzle 5 are supplied with fuel from the reservoir 12, and the fuel in the reservoir 12 is supplied and replenished by the third liquid pump 11. The fuel that stores in reservoir 12 plays the buffer memory effect, when the long-time shutdown of alcohol combustion stove, its inside pipeline leads to the pipeline to be emptied because fuel natural evaporation, phenomenon such as fuel refluence, the fuel of reservoir 12 buffer memory also can not follow and is emptied (the fuel of reservoir 12 buffer memory is enough relatively, and can not produce the refluence phenomenon), therefore, when alcohol combustion stove cold start starts the start-up, reservoir 12 can be at once to first liquid pump 41, second liquid pump 42, gasification ring 2, straight spray tube 3 and fuel atomizing nozzle 5 transport fuel, reduce the pipeline again and fill with the time that the fuel needs, effectively accelerate the ignition time when alcohol combustion stove cold start starts the start-up.
The reservoir 12 adopts a structure mode of high-level input and low-level output, the technical scheme can further prevent the reservoir 12 from flowing back fuel, and the first liquid pump 41 and the second liquid pump 42 can suck the fuel from the low level of the reservoir 12, so that air is effectively prevented from being sucked from the reservoir 12.
Water level detection device 13 is used for detecting the water level height in reservoir 12, water level detection device 13 can constantly detect the water level height in the reservoir 12, when the water level is less than the medium water level of setting for, third liquid pump 11 will initiatively be to reservoir 12 supply fuel, when the water level is in the high water level, third liquid pump 11 stops to supply fuel to reservoir 12, the water level is less than the medium water level of setting for and the water level still constantly descends (or the amplitude of rise is slow) in the certain time after third liquid pump 11 works, can judge that it can't normally obtain liquid fuel for the alcohols burning kitchen, need change fuel delivery bottle, at this moment, the alcohols burning kitchen can initiatively shut down and send relevant suggestion, technical personnel in the field all can understand.
