Utility model content
In order to solve the above technical problems, the utility model provides a kind of anti-backfire that can prevent tempering, safe
Gas burner.
To achieve the above object, the technical solution adopted in the utility model is a kind of anti-backfire gas burner, including combustion
Burner ontology, burner body are equipped with combustion barrel, and structural feature is, combustion barrel is externally connected with nozzle external member, combustion barrel with
Check disk is equipped between nozzle external member, check disk includes fan frame and fan plate, is opened upwards after fanning plate stress, the nozzle external member
Including outer nozzle and inner nozzle, inner nozzle is flexibly connected with combustion barrel, before the burner body is equipped with control inner nozzle
The control knob moved afterwards.
Fan frame includes chassis and the stand vertical with chassis, the end of stand as a further improvement of the utility model,
Equipped with around stand and with the vertically disposed fan bar of stand.
Fan plate a side is flexibly connected with fan bar as a further improvement of the utility model, and fan plate is equipped with fine and closely woven
Air hole.
Fan plate is several as a further improvement of the utility model, and several fan board groups are at a closure plane.
Outer nozzle is equipped with contraction mouth as a further improvement of the utility model, and the junction of contraction mouth and outer nozzle is
Chamfer is arranged.
Contraction mouth is made of refractory metal as a further improvement of the utility model,.
The maximum opening angle of fan plate is 40 degree as a further improvement of the utility model,.
The utility model has the beneficial effects that：Reasonable design, it is simple in structure, can prevent tempering the case where generation, together
When increase the work safety of user, reduce danger, pressure ignition further, it is possible to increase, increase efficiency of combustion.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the fan plate overlooking structure diagram of the utility model；
Wherein, 1- burner bodies, 2- combustion barrels, 3- check disks, 4- fan framves, 5- fan plates, 6- outer nozzles, 7- inner nozzles,
8- control knobs, 9- chassis, 10- stands, 11- fan bar, 12- contraction mouths.
Specific implementation mode
Explanation is further explained to the utility model below in conjunction with the accompanying drawings, but does not limit the protection model of the utility model
It encloses.
As shown in Figure 1 to Figure 2, a kind of anti-backfire gas burner, including burner body 1, burner body 1 are equipped with
Combustion barrel 2, the combustion barrel 2 are externally connected with nozzle external member, and check disk 3, check disk are equipped between combustion barrel 2 and nozzle external member
3 include fan frame 4 and fan plate 5, is opened upwards after fanning 5 stress of plate, the nozzle external member includes outer nozzle 6 and inner nozzle 7, interior spray
Mouth 7 is flexibly connected with combustion barrel 2, and the burner body 1 is equipped with the control knob 8 that control inner nozzle 7 is moved forward and backward；It is described
Fan frame 4 include chassis 9 and the stand 10 vertical with chassis 9, the end of stand 10 is equipped with around stand 10 and hangs down with stand 10
The fan bar 11 being directly arranged；Described 5 a side of fan plate is flexibly connected with fan bar 11, and fan plate 5 is equipped with fine and closely woven air hole；It is described
Fan plate 5 be several, several fan plates 5 one closure plane of composition；The outer nozzle 6 be equipped with contraction mouth 12, contraction mouth 12 with
The junction of outer nozzle 6 is arranged for chamfer；The contraction mouth 12 is made of refractory metal；Fan the maximum open-angle of plate 5
