Conjunction portion and diffusion part；The entrance of the opposite contraction flow region in outlet of the nozzle；The nozzle includes ontology and described of perforation
The gas channel of body；
It is characterized in that：
The cross section of the gas channel outlet of the nozzle is polygon or strangles Lip river polygon and be non-circular；The mixing
The cross-sectional structure of the inner cavity in portion is identical as the cross-sectional structure that the gas channel exports.
For further increase injector compressive resistance fluctuating nature and further decrease it is hot under energy loss, Ke Yi
The gas channel includes the air inlet section for being sequentially communicated setting, surge chamber and at least two air outlet sections along airflow direction；It is each described
Air outlet section is set up in parallel, and the cross-sectional area of air inlet section described in the cross-sectional area sum < of the entrance face of each air inlet section
The cross-sectional area of surge chamber described in <.The compressive resistance fluctuating nature of injector is further improved by the design of surge chamber, together
When each section of size design can ensure the requirement of injection effect again, obtain good air mixed effect.
Preferably, each air outlet section may each comprise linkage section, contraction section and outlet section；Wherein, the linkage section is
Uniform internal diameter circular hole；The contraction section is taper circular hole；The cross section of the outlet section is polygon or strangles Lip river polygon and be non-
It is round；
Also, the cross-sectional area of the linkage section is more than the cross-sectional area of the outlet section.The structure design is in above-mentioned side
On the basis of case, injection effect is further improved.
It is preferred that the cross section of the outlet section is rectangle or triangle.
The cross section of the air inlet section and the surge chamber is circle.
To be further ensured that injection effect, the assembling structure between nozzle and ejector pipe is limited, the ontology can be connected
It is connected on holder, the holder passes through contraction flow region described in flanged joint.
Preferably, the cross section of the contraction flow region can be ellipse, and the cross section of the diffusion part is circle.The structure
Injection effect is good, and air-flow is unobstructed.
Compared with prior art, gas cooker injector provided by the present invention is special by nozzle passage and injection tube passage
The design of different structure so that fire-resistant atmospheric pressure fluctuating nature of the present invention is good, and is substantially reduced in hot lower heat loss.

Specific implementation mode
Below in conjunction with attached drawing embodiment, present invention is further described in detail.
As shown in Figures 1 to 5, which includes nozzle 1, ejector pipe 2 and connection successively along airflow direction
The holder 3 of the two.
Wherein, nozzle 1 includes ontology 11 and penetrates through the gas channel of ontology 11 along airflow direction.
Gas channel is divided into air inlet section 12, surge chamber 14 and at least two air outlet sections 13 along airflow direction；This implementation
There are two example air outlet sections 13, more can also be arranged.Each air outlet section 13 is set up in parallel, surge chamber 14 and air inlet section 12 it is transversal
Face is circle, and the cross-sectional area < surge chambers of the cross-sectional area sum < air inlet sections 12 of the entrance face of each air inlet section 12
14 cross-sectional area.
The cross-sectional area of air inlet section 12 and surge chamber 14 is circle.
Each air outlet section 13 includes the linkage section 131, contraction section 132 and outlet section 133 being connected to surge chamber 14；Wherein,
Linkage section 131 is uniform internal diameter circular hole；Contraction section 132 is along the diminishing taper circular hole of airflow direction internal diameter；Outlet section 133
Cross section is polygon or strangles Lip river polygon and be non-circular, such as rectangle, triangle, pentagon, hexagon etc.；This implementation
It is rectangle in example.
The cross-sectional area of linkage section 131 is more than the cross-sectional area of outlet section 133.
Ejector pipe 2, the change along airflow direction according to cross section are divided into contraction flow region 21, mixing unit 22 and diffusion part 23；Spray
The entrance of the outlet opposite direction contraction flow region 21 of mouth 1.
The cross-sectional structure of the inner cavity of mixing unit 22 is identical as the cross-sectional structure of outlet section 133, is rectangle；Contraction flow region 21
Cross section be ellipse, the inner cavity of diffusion part 23 is along the diminishing taper circular hole of airflow direction internal diameter, and cross section is
It is round.
Holder 3 is the connecting component of nozzle 1 and ejector pipe 2；Ontology 11 is connected on holder 3, and holder 3 passes through flange 31
It is connected on the outer wall of contraction flow region 21.
When work, combustion gas sprays into ejector pipe via the air inlet section of nozzle, surge chamber, air outlet section successively, introduces after air again
Enter downstream via contraction flow region, mixing unit and diffusion part successively；Combustion gas obtains slow for the first time in flow process in surge chamber
Punching, obtain second of buffering in outlet section, into mixing unit after obtain third time buffer；Therefore, the anti-barometric wave of the injector
Kinetic force is very good, even if gas pressure fluctuation is larger, still is able to ensure good injection effect, avoids hot lower thermic load damage
It loses.
