The cross-sectional structure that the cross-sectional structure of the inner chamber in portion is exported with the gas channel is identical.
For further improve injector compressive resistance fluctuating nature and further reduce it is hot under energy loss, Ke Yi
The gas channel includes being sequentially communicated air inlet section, surge chamber and at least two air outlet sections of setting 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 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 ensure that 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 Le Lip river polygon and is non-
It is circular；
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.
For being further ensured that injection effect, the body can be connected by the assembling structure between spacing nozzle and induction tunnel
It is connected on support, the support connects the contraction flow region by flange.
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 kitchen ranges injector provided by the present invention passes through nozzle passage and injection tube passage is special
The design of different structure so that fire-resistant atmospheric pressure fluctuating nature of the present invention is good, and substantially reduces in hot lower heat loss.

Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 5, the gas kitchen ranges injector includes nozzle 1, induction tunnel 2 and connection successively along airflow direction
Both supports 3.
Wherein, nozzle 1 includes body 11 and the gas channel along airflow direction insertion body 11.
Gas channel is divided into air inlet section 12, surge chamber 14 and at least two air outlet sections 13 along airflow direction；This enforcement
Example air outlet section 13 has two, it is also possible to arrange more.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 section 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 linkage section 131, contraction section 132 and the outlet section 133 connected with surge chamber 14；Wherein,
Linkage section 131 is uniform internal diameter circular hole；Contraction section 132 is taper circular hole diminishing along airflow direction internal diameter；Outlet section 133
Cross section is polygon or Le Lip river polygon and is non-circular, such as rectangle, triangle, pentagon, hexagon etc.；This enforcement
It is rectangle in example.
Cross-sectional area of the cross-sectional area of linkage section 131 more than outlet section 133.
Induction tunnel 2, is divided into contraction flow region 21, mixing unit 22 and diffusion part 23 along airflow direction according to the change of cross section；Spray
