Below in conjunction with the attached drawing in embodiment of the present invention, the technical solution in embodiment of the present invention is carried out clear
Chu, be fully described by, it is clear that described embodiment only a part of embodiment of the present invention, rather than whole realities
Apply mode.Based on the embodiment in the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, belongs to the scope of protection of the invention.
As shown in Figure 1, with reference to Fig. 2 and Fig. 3, anti-backfire kitchen range of the invention, it include burner 1, combustion gas inlet pipe 2, into
Air hose 3, oxygenation wind turbine 4, three-way pipe 5, circuit control device 7 and gas valve 9.
Wherein, burner 1 is respectively communicated with as prior art part, combustion gas inlet pipe 2, blast pipe 3, combustion gas inlet pipe 2 is passed through
Combustion gas, blast pipe 3 are passed through the burning in burner 1 of oxygen, combustion gas and oxygen.
When oxygenation 4 failure of wind turbine occurs, wind pressure is too low in blast pipe 3, and combustion gas inlet pipe 2 is still passed through combustion gas, easily draws
Beam back fiery burning.The generation of the above situation in order to prevent, as shown in Fig. 2, 5 both ends of three-way pipe are respectively arranged with air inlet 51, go out
Air port 52 and blowing mouth 58, air inlet 51 connect oxygenation wind turbine 4, and air outlet 52 connects blast pipe 3, wherein blowing mouth 58 and combustion gas
Valve 9 links, and the gas supply in combustion gas inlet pipe 2 is cut off when wind pressure is too low in blast pipe 3.
Wherein, as shown in figure 3, gas valve 9 includes valve body 91 and hollow piston 92, hollow piston 92 is arranged in valve body 91
And be slidably connected therewith, air inlet 911, gas outlet 912, fuel gas inlet 913 and gas outlet 914 are provided with valve body 91, into
Connection interface 93 is provided between gas port 911 and gas outlet 912, blast tube 94, hollow work are provided among hollow piston 92
Blast tube 94 does not connect closed connection interface 93 plug 92 with fuel gas inlet 913, gas outlet 914 at the same time when moving to bottom,
Hollow piston 92 connects interface 93 and connects the combustion gas of the connection of blast tube 94 at the same time of air inlet 911, gas outlet 912 when moving to top
Import 913 and gas outlet 914, combustion gas inlet pipe 2 connect fuel gas inlet 913, and gas outlet 914 connects burner 1, blowing mouth 58
Connect air inlet 911.In this way, when oxygenation 4 normal operation of wind turbine, wind pressure driving hollow piston 92 moves upwards in blast pipe 3,
Blast tube 94 connects fuel gas inlet 913 and gas outlet 914, and combustion gas enters in burner 1;When occurring when oxygenation wind turbine 4 therefore
When hindering or is out of service, wind pressure is too low in blast pipe 3, and hollow piston 92 moves downward, and blast tube 94 cuts off fuel gas inlet
Connection between 913 and gas outlet 914, combustion gas cannot be introduced into burner 1, so as to can not also be tempered into blast pipe 3, prevent
Non-return fire burning.Specifically, further including circuit control device 7,912 face circuit control device 7 of gas outlet is blown.It is in this way, right
In the circuit control device 7 of electronic component composition, by blowing a cold wind over to it, cleaning and cooling effect are played, extension uses the longevity
Life.Specifically, circuit control device 7 is set away from 1 high-temperature region of burner, prevent high temperature from damaging.Specifically, 911 He of air inlet
The supporting part 95 vertical with air inlet 911 and 912 central axes of gas outlet is provided between gas outlet 912, is set among supporting part 95
Connection interface 93 is equipped with, 92 end face connection interface 93 of hollow piston is provided with sealing ring 96, in this way, can improve sealing effect
Fruit, of course, seal washer can also be set at 94 both ends of blast tube, prevents gas leakage.In order to help hollow piston 92 to reset,
(the first back-moving spring 97 is further included, 97 both ends of (the first back-moving spring support 92 top end surface of valve body 91 and hollow piston.First is multiple
The spring ratio of position spring 97, can be adjusted according to wind pressure pressure.
Liquid, which pours in down a chimney, in order to prevent influences 4 service life of oxygenation wind turbine, and the middle pipeline section bottom of three-way pipe 5 of the present invention is provided with discharge opeing
Groove 53, is provided with leakage fluid dram 57 in sump pit 53, the middle pipeline section bottom of three-way pipe 5 is provided with sump pit 53, is provided with side wall

56 both ends of resetting spring connect 5 inner wall of piston 55 and three-way pipe respectively, and piston 55 axially moves to logical along 5 middle pipeline section of three-way pipe
When wind groove 54 is middle, the closed sump pit 53 of 55 side wall of piston, while 55 both sides space of piston is connected by ventilation slot 54, sump pit
Leakage fluid dram 57 is provided with 53.In this way, the fresh oxygen that oxygenation wind turbine 4 sucks enters in three-way pipe 5 through air inlet 51, through outlet air
Mouth 52 enters in blast pipe 3, and leakage fluid dram 57 pours in down a chimney liquid for discharge.When oxygenation wind turbine 4 is started to work, wind pressure reaches setting
Value, wind pressure promote piston 55 to move, closed sump pit 53, increase oxygen newly and are reacted by ventilation slot 54 into participation in burner;
The return under the effect of 56 elastic force of second back-moving spring of piston 55 when oxygenation wind turbine 4 is stopped, leakage fluid dram 57 opens, for into
The liquid for entering three-way pipe 5 is discharged, and is prevented liquid from pouring in down a chimney damage or is shortened the service life of oxygenation wind turbine 4;Piston 55 exists
It is subject to 56 elastic force of second back-moving spring effect automatic airtight air inlet 51 under 4 off working state of oxygenation wind turbine, can prevents from burning
The corrosivity or polluted gas of generation are poured in down a chimney into oxygenation wind turbine 4, extend its service life.Specifically, the piston 55 wraps
Sealed bottom piece 551 and piston sheet 552 are included, sealed bottom piece 551 and piston sheet 552 are mutually perpendicular to fix, and sump pit 53 is remote
Groove edge height of the groove of 51 side of air inlet along height higher than it close to 51 side of air inlet.In this way, the groove that sump pit 53 is higher
Edge can play sealed bottom piece 551 spacing effect.Specifically, the second back-moving spring 56 be arranged at piston sheet 552 with
In the pipeline section of 51 side of air inlet, less catalytic combustion exhaust gas, prevents it to be corroded.
