Description of drawings

Fig. 1 is a specific embodiment structure chart of the present utility model.

Fig. 2 is an application example schematic diagram of the present utility model.

Specific embodiment

For make the auditor of Patent Office especially the public can further understand architectural feature of the present utility model and beneficial effect thereof, applicant spy reaches embodiment in conjunction with the accompanying drawings and is described below the specific embodiment of the present utility model is detailed:

See also Fig. 1, having provided the metal and preferred shape of usefulness is the gaseous mixture cylindrical shell 1 of cylinder, this gaseous mixture cylindrical shell 1 is complete hollow, thereby constitutes mixed air cavity 11, and the bottom of mixed air cavity 11 should be that the top of sealing then is uncovered.The outer wall of gaseous mixture cylindrical shell 1 and on the upper side the side extended a holder 12, press present embodiment, the holder of being recommended 12 is just as flange, so is a kind of concrete manifestation form of fixed disk; If change a plurality of fixing feet into around gaseous mixture cylindrical shell 1, so also be feasible fully, therefore know, should not be subjected to the restriction of given example for the shape of holder 12.The outer wall of gaseous mixture cylindrical shell 1 has been received an air intake interface 13 near the bottom, this air intake interface 13 is used for being connected with air blast (being generally vortex flow blower), will be caused in the mixed air cavity 11 by the air that air blast 9 blasts by the air inlet 131 of air intake interface 13.The uncovered position on mixed air cavity 11 tops that burner plate 2 solid weldings are mentioned in front, being covered with on burner plate 2 has gaseous mixture through hole 21, the angle of inclination of gaseous mixture through hole 21 to be preferably 2-10 °, is 3-7 ° preferably, is 4-6 ° better.With present shown position state is example, all gaseous mixture through holes 21 are tilted to the left without exception, this is for consistent with the rotation direction of helical blade 7, determined the air-flow rotation direction of gaseous mixture because the rotation direction of helical blade 7 is the hand of spiral, so the incline direction of gaseous mixture through hole 21 must be taken into account in this.If the rotation direction of helical blade 7 and current icon opposite states, the incline direction of gaseous mixture through hole 21 is also opposite so.See again, central authorities at burner plate 2 are that 2 side central authorities outward of burner plate are formed with a pit, constitute igniter cap chamber 22 by this pit, the self-evident effect in this igniter cap chamber 22 is to hold for Chang Minghuo cap 3, is furnished with pore 31 between same on the Chang Minghuo cap 3.Chang Minghuo cap 3 plays the effect of little fire.

Please continue to see Fig. 1, air-spreading disk 4 is set at the mixed air cavity 11 of gaseous mixture cylindrical shell 1 by the below, more definite position be occupy air intake interface 13 air inlet 131 above, fix with the chamber wall of mixed air cavity 11.Between on the air-spreading disk 4, be furnished with passage 41, because the setting of air-spreading disk 4, thereby the lower part of whole mixed air cavity 11 is separated out an air-inlet cavity 111, and the air in the air-inlet cavity 111 enters the mixed air cavity 11 from passage 41, mixes with the liquefaction gas phase of being introduced by liquefied gas inlet tube 6.Liquefied gas inlet tube 6 penetrates from the bottom of gaseous mixture cylindrical shell 1, passes the central authorities of air-spreading disk 4 again, and the top that its spout 61 is positioned at air-spreading disk 4 promptly is stuck in air-spreading disk 4.Whether entering by second valve 62 on its pipeline of liquefied gas controlled, and closes, and then liquefied gas inlet 63 can't bleed, and vice versa.Naked light pipe 5 penetrates from the bottom of gaseous mixture cylindrical shell 1 too, until wear and and be stuck in the igniter cap chamber 22 of burner plate 2 central authorities, the Chang Minghuo spout 51 of naked light pipe 5 is in alignment with in the cap chamber that tips upside down on the Chang Minghuo cap 3 in the igniter cap chamber 22.First valve 52 is closed in the unlatching of naked light pipe 5 or close and be controlled by first set on its pipeline valve 52, and the air inlet inlet 53 of naked light pipe 5 can't air inlet, and vice versa.Banking fire circle 8 is found a place on burner plate 2, to working the effect of going along with sb. to guard him around the burner plate 2, is banking fire.

By above-mentioned explanation as can be known, because helical blade 7 (being preferably uniform three pieces) and be opened in the synergy of the gaseous mixture through hole 21 of the inclination on the burner plate 2, make air-flow produce rotation direction, more specifically produce inward turning, therefore combustion efficiency is highly desirable, through specialized department the utility model structure has been carried out testing (Pekinese is by the mechanism for testing of national appointment), compare with the conventional structure in the prior art, the result is: can save liquefied gas 35% in the unit interval, carbon monoxide content in the flue gas only is 0.008%, ignition temperature reaches 1200 ℃, and noise reduces by 40%.Above-mentioned test be with prior art in carry out on the roughly the same kitchen range top, visible the utility model can show ultimate attainment good effect.

See also Fig. 2, the utility model structure is installed on the kitchen range top 10, specifically be with screw with aforesaid holder 12 be preset in the fixture that being used on the kitchen range top 10 scoop out holder 12 and fix, by pipeline air intake interface 13 is connected with air blast 9, the air inlet inlet 53 of naked light pipe 5 and the liquefied gas inlet 63 of liquefaction tracheae 6 dock with source of the gas such as liquid gas storage tank (steel cylinder) respectively.Concrete igniting, flame-out mode and prior art are identical, reach so the applicant is no longer superfluous.But need following 2 points of explanation, the one, mentioned above the wording of liquefied gas should being appreciated that out that natural gas or other similar source of the gas all can adapt to; The 2nd, through the applicant the utility model structure and prior art have been carried out contrast service test (under the confidential state), improved nearly 3 times than prior art service life.
