Embodiment
The present invention is described in further detail below in conjunction with attached drawing embodiment.
As depicted in figs. 1 and 2, a kind of gas burner, including pedestal 1, mixing chamber 2, external ring fire cover 3, interior ring fire cover 4 and
Ignition electrode 6, said base 1 have been internally formed cavity, and mixing chamber 2 is arranged on the top of pedestal 1, external ring fire cover 3 and interior ring fire
Lid 4 is inside and outside respectively to be arranged on mixing chamber 2.Inner and outer rings, which are respectively formed with, in above-mentioned inner and outer rings fire cover 3,4 mixes air cavity 30,40,
And the inner and outer rings are mixed air cavity and are connected respectively by corresponding blast tube in mixing chamber 2 with cavity.In addition, the outside of mixing chamber 2
It is further opened with auxiliary air on end, 21, supplement auxiliary air so as to the burning of flame on internal ring fire cover 4.
As shown in Fig. 3~5 and Fig. 8, above-mentioned interior ring fire cover 4 includes the fire cover body 41 of open topped and lid is located at the fire cover
The lid 42 of 41 oral area of body.Wherein, the shape of fire cover body 41 is substantially cylindrical, is divided into fiery portion 415 and connection up and down
Portion 416, corresponding, above-mentioned lid 42 is in the form of annular discs.The inner peripheral surface of fire cover body 41 encloses to set to form inner ring and mix air cavity with lid 42
40, go out on the side wall in fiery portion 415 and be circumferentially laid with fire output hole 411, each fire output hole 411 mixes air cavity 40 with above-mentioned inner ring and connects
It is logical, a diameter of 2~2.8mm of fire output hole 411 in the present embodiment.
Further, 421 evagination of periphery of lid 42 is circumferential vertically downwards along the periphery 421 of lid 42 in fire cover body 41
Extend and form rain visor 43, when such discharge flow to the edge of lid 42, can flow, drip along rain visor 43, so that anti-
Only discharge is flowed into fire output hole 411, prevents fray-out of flame, avoids discharge from blocking fire output hole 411, so as to ensure stable, efficient, equal
Burn evenly.Preferably, in the present embodiment, which is by the width A that the periphery 421 of fire cover body 41 extends downwardly
0.5~3mm, effectively avoids discharge from flowing backward to the intersection of lid 42 and fire cover body 41 and takes advantage of a situation and flow into fire output hole 411.
Further, the bottom surface of rain visor 43 and the periphery 421 of lid 42, which is enclosed, sets to form groove 44 of cutting off the water supply, even if so there is portion
Discharge is divided to be flowed backward to along rain visor 43 at 42 bottom surface of lid, since groove 44 of cutting off the water supply is closed annular groove, the discharge flowed into is only
It can be circulated in groove periphery 421 of cutting off the water supply without flowing out, will not flow into fire output hole 411 along fire cover body 41, thoroughly prevent
The generation of discharge backward flow problem, further avoids fire output hole 411 from being blocked.Preferably, in the present embodiment, the width for groove 44 of cutting off the water supply
Degree B is 0.5~3mm.
In addition, go out on the side wall in fiery portion 415 413 (this reality of fire hole for being further opened with mixing air cavity 40 with above-mentioned inner ring and connect
It is 3 to apply fire hole 413 in example), the periphery 421 of the fire cover body 41 of the top of fire hole 413 horizontally outward extends and is formed
Ignition needle protection umbrella 5, the ignition needle protection umbrella 5 are located at the top of ignition electrode 6.The bottom on the periphery edge of the ignition needle protection umbrella 5
It is again provided with the rain visor 43 extended vertically downwards, and the rain visor 43 of the part and other rain visors 43 on lid 42
It is connected as one so that the bottom surface of ignition needle protection umbrella 5 connects with above-mentioned groove 44 of cutting off the water supply and forms the ring-type slot structure of closure, into
One step expands the capacity for groove 44 of cutting off the water supply, so that more discharges can be accumulated, and then can be better protected from discharge and flow into out
Fire hole 411 and fire hole 413, ensure normal ignition and go out fire.
Stable flame hole 412 is further opened with addition, going out on the side wall in fiery portion 415, which is opened in fire output hole 411
Lower section is simultaneously arranged at intervals with above-mentioned fire output hole 411, so as to be further ensured that the flame stabilization burning of fire output hole 411.
Embodiment 2：
As shown in Fig. 6, Fig. 7 and Fig. 9, as different from Example 1, in the present embodiment, go out on the side wall in fiery portion 415 and also open
Equipped with mixing guarantor's fire hole 414 that air cavity 40 connects with above-mentioned inner ring, 421 water of periphery of the fire cover body 41 of the top of guarantor's fire hole 414
Put down and stretch out and form the fiery eaves 7 of guarantor.
In the present embodiment, rain visor 43 is provided only on ignition needle protection umbrella 5 and protects the bottom at the edge of fiery eaves 7.Specifically,
The bottom at the edge of ignition needle protection umbrella 5 is relatively set with rain visor 43 at two, and each rain visor 43 is by ignition needle protection umbrella 5
Edge tilt, which stretches out, to be formed.Fire hole 413 is opened in the side of the fire cover body 41 between rain visor 43 at above-mentioned two
On wall.The rain visor 43 for protecting the bottom of fiery eaves 7 is arranged on the edge of the fiery eaves 7 of the guarantor opposite with fire cover body 41, and also by
The corresponding edge of the fiery eaves 7 of guarantor is obliquely outward to be formed.
