Specific embodiment
This utility model 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 successively nozzle 1, induction tunnel 2 and connection 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 strangles Lip river polygon and for 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, contraction flow region 21, mixing unit 22 and diffusion part 23 are divided into along airflow direction according to the change of cross section；Spray
