Background technology
All there is a common problem in the stove and accessory of existing structure whatsoever, and that is exactly a stove and accessory when burning finishes, and causes tempering sometimes, and this tempering may enter in the gas pipeline, and has the hidden danger of blast on fire.
The combustion rate that second problem that existing stove and accessory exists is stove and accessory is generally not high, and the combustion gas utilization rate is lower.In order to improve the combustion rate of stove and accessory, people have done many researchs, disclose a kind of Vortex furnace unit as Chinese patent literature CN2511890.Can carry out secondary with near the air the burner after it can make combustion gas eject from fire hole and fully mix, combustion gas can fully be burnt, thus energy savings environmental protection again.Chinese patent literature CN201062791 discloses a kind of cyclone type burner for another example, its general structure is for comprising base, air inlet is arranged at described base bottom, be placed with cyclone disk in the base, forming certain interval between cyclone disk and the base communicates with air inlet, be distributed with a series of inclined holes on the sidewall circumference of cyclone disk, described cyclone disk is provided with loam cake; Combustion gas and Air mixing gas enter the gap that forms between cyclone disk and the base from the air inlet of base bottom, and under the effect of blower fan, inclined hole can make mixing air that rotation rapidly and up soaring takes place in cyclone disk, thereby make and obtain good mixed combustion efficiency, it is more even to make that combustion gas and air mix, and thermal conversion efficiency is higher.
Above-mentioned two kinds of stove and accessorys all adopt vortex principle, can improve certain combustion rate of stove and accessory, though fully mix but can carry out secondary with near the air the burner after above-mentioned first kind of stove and accessory can make combustion gas eject from fire hole, improve the combustion rate of a part of combustion gas, but, it mixes for the first time is the conventional hybrid mode that adopts, the combustion gas mixing effect is undesirable for the first time, though, carried out the secondary mixing, but this stove and accessory is owing to be to mix with natural air, and its total combustion rate is still lower.Above-mentioned second kind of stove and accessory be not owing to there is secondary to mix, and its combustion rate neither be very desirable.In addition,, can produce a large amount of carbon monoxide unavoidably and be discharged in the air because the combustion rate of above-mentioned stove and accessory is lower, on the one hand a large amount of consumes energy, the carbon monoxide pollution environment of Chan Shenging endangers the healthy of contact personnel on the other hand.
Summary of the invention
The utility model purpose is to overcome above-mentioned defective, and a kind of safety, combustion gas mixing better effects if are provided, the efficient energy-saving gas stove and accessory that efficiency of combustion is higher.
A kind of safe and energy-saving gas stove is provided, comprise shell, the burning cavity, described combustion chamber body is positioned at the top of shell, in described shell, burning cavity bottom is provided with jet mixer, the port of export of described jet mixer links to each other with the bottom surface of described burning cavity, and communicate with the combustion chamber of described burning cavity, be provided with a flaring pressure air air intake fluidic channel that is up-small and down-big in the described jet mixer lower end, be provided with fuel gas inlet on the outer wall of described jet mixer, the air outlet of a described pressure air air intake fluidic channel communicates with described fuel gas inlet.
As to improvement of the present utility model, in described jet mixer, the air outlet of described pressure air air intake fluidic channel top also is provided with down little gas mixing chamber of big inverted tubaeform.
As to further improvement of the utility model, be provided with an annular negative pressure cavity in the air outlet periphery of a described pressure air air intake fluidic channel, described fuel gas inlet communicates with described annular negative pressure cavity.
As further improving to of the present utility model, on described burning cavity, be provided with the oblique secondary pressure air duct of many direction unanimities, be provided with secondary pressure air air inlet on described shell, described secondary pressure air air inlet communicates with described oblique secondary pressure air duct.
