It on stove, and is connect with gas source (not shown), combustion gas is made to light burning by burner 100, supply user cooks.
Please refer to fig. 5, the burner 100 of embodiment of the present invention includes distributor 30, distributor 30 includes ontology
31 and at least two ejector pipes 32, ontology 31 is formed at least two mixed gas slots 311, and at least two settings of ejector pipes 32 exist
It is connected to below ontology 31 and at least two mixed gas slots 311 respectively, when burner 100 is horizontally arranged, at least two are drawn
Penetrating has the angle between at least one ejector pipe 32 and horizontal direction in pipe 32 be 15 ° -75 °, and at least one ejector pipe 32
It is substantially vertical with horizontal direction.
In the present embodiment, ejector pipe 32 is connected to mixed gas slot 311, and forms gas vent 323 in connectivity part,
In this way, mixed gas is transported in mixed gas slot 311 by gas vent 323 from ejector pipe 32.Wherein, incline with horizontal direction
The gas vent 323 that oblique ejector pipe 32 is formed in mixed gas slot 311 is substantially oval, and vertical with horizontal direction draws
It is substantially rounded to penetrate the gas vent 323 that pipe 32 is formed in mixed gas slot 311.
In the burner 100 of embodiment of the present invention, inclined ejector pipe 32 can be in 100 height of burner and lateral ruler

If ejector pipe 32 is arranged and the angle of horizontal direction is too small, the long axis of gas vent 323 is longer and is exponentially increased, to guarantee gas
Body outlet 323 is located in mixed gas slot 311, and the radial dimension of ontology 31 needs equally to increase, however, oversized
Ontology 31 be unfavorable for the miniaturization of burner 100 again, while increasing the cost of manufacture again.
So when the angle between ejector pipe 32 and horizontal direction is 15 ° -75 ° burner 100 can be conducive to
In the case where miniaturization, the manufacture difficulty and production cost of burner 100 can be also reduced.Further, since ejector pipe 32 with mix
Gas grooves 311 are connected to, and mixed gas is easy to cause to rush to the flame near gas vent 323 after the ejection of gas vent 323
It hits, and the long axis of gas vent 323 is longer, the area of gas vent 323 is bigger, and the impact force of the mixed gas after ejection is got over
It is small, so passing through the tilt angle of appropriate adjustment ejector pipe 32, the length of the long axis of gas vent 323 can be increased, be conducive to
The flame of ontology 31 is more uniform.
It should be noted that the embodiment of the present invention forms two mixed gas slots 311, corresponding each mixing with ontology 31
