The specific embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Regularly back pressure control type full-automatic energy-saving gas furnace comprise furnace shell 1 and equipped on it burner 2, by sense formula impulse generator 10, battery case 13, air inlet pipe 14 and fire regulating valve door 15, regularly master switch 12 is installed on the furnace shell 1 positive side, equipped pressure control switch valve 5 between timing master switch 12 and fire regulating valve door 15; Swing kitchen range frame 22 hinges that have cross bar 21 are contained on furnace shell 1 upper surface; rocking arm 3 is hinged on burner 2 following sides; vertical rod 20 upper ends that are positioned at burner 2 are connected with cross bar 21; vertical rod 20 lower ends are hinged on the rocking arm 3; spring positioning seat 8 is packed on pressure control switch valve 5 outer walls; drive link 4 is inserted in spring positioning seat 8 holes slidably; the two ends difference rocking arm 3 of drive link 4 and the switch valve control rocking bar 9 on the pressure control switch valve 5 are hinged; spacing catch 6 is with being contained on the drive link 4; compression spring 7 is sleeved on the drive link 4, and its both ends of the surface contact cooperation with spring positioning seat 8 with spacing catch 6 respectively; axial location; The travel switch of connecting with timing master switch 12 and inductance type impulse generator 10 11 is packed on furnace shell 1 position that is positioned at pressure control switch valve 5 one sides, and travel switch 11 cooperates with drive link 4 cantilever terminations; Electric induction head 16 and inboard pulse firing 18, outside pulse firing 19 is configured on the burner 2, its electric induction head 16 is between medial and

lateral pulse firing

18,19, and lead is connected electric induction head 16 medial and

lateral pulse firings

18,19 and inductance type impulse generator 10 respectively.Regularly master switch 12 is made of mechanical timer 25 and 26 assemblings of push type control valve, and valve 24 upper surfaces of its push type control valve 26 contact cooperation with the timing rocking arm 23 of mechanical timer 25.On the upper surface of furnace shell 1, fixedly mount fixedly kitchen range frame 17 with respect to swing kitchen range frame 22 1 sides.

During use, at first rotating machinery timer 25 is tentatively determined burning times, opens push type control valve 26 under mechanical timer 25 effects, because do not have cooker on the stove and accessory this moment, pressure control switch valve 5 cuts out, and burner 2 places do not have combustion gas; When cooker being placed on burner 2 tops, the swing kitchen range frame 22 that under the effect of cooker gravity original position is tilted is pressed and is changeed, by cross bar 21, vertical rod 20, rocking arm 3, drive link 4, switch valve control rocking bar 9 pressure control switch valve 5 is opened, combustion gas enters burner 2, meanwhile drive link 4 cantilever terminations promote travel switch 11, the signal of telecommunication is transferred to inductance type impulse generator 10, between electric induction head 16 and medial and lateral pulse firing 18,19, produces the pulse spark, light burner 2; When cooker leaves burner 2, under compression spring 7 and spacing

catch

6,8 mating reactions of spring positioning seat, make drive link 4 counter motions, by switch valve control rocking bar 9 pressure control switch valve 5 cuts out, it is flame-out to cut off burner 2 gas supplies, and swing kitchen range frame 22 and be in heeling condition this moment.In timing, cooker is constantly taken, is taken off, the automatic control state repeatedly that burner 2 promptly is in ignition, extinguishes.Flame size adjustment when fire regulating valve door 15 is only finished burner 2 burnings is used.
