Abstract

A burner comprising a base cup, an annular flame splitter, and a flame cover. The base cup comprises an air inlet channel and two nozzles in communication with the air inlet channel and arranged upwards. The annular flame splitter arranged on the base cup comprises two Venturi tubes respectively arranged opposite the two nozzles. The annular flame splitter is separated from the base cup to form a gap, thus allowing primary air to enter the two Venturi tubes from the gap to be mixed with a fuel gas sprayed into the two Venturi tubes by the two nozzles to form a gaseous mixture. Groove openings are formed on the top of the annular flame splitter in communication with the mixing cavity. The flame cover covers the mixing cavity and limits the groove openings to define the outlet for the gaseous mixture, thus forming a flame ring.

First claim

What is claimed is:

1. A burner, comprising:
a bottom cup having a gas input passage and two nozzles communicated with the gas input passage and arranged upwards;
a ring-shaped flame distributor disposed to the bottom cup and comprising two venturi tubes respectively opposite to the two nozzles, the flame distributor being spaced apart from the bottom cup to define a gap therebetween, such that a primary air is allowed to enter the two venturi tubes through the gap to mix with a fuel gas sprayed into the two venturi tubes from the two nozzles so as to form a mixed gas, the flame distributor being provided with a ring-shaped mixing chamber communicated with the venturi tubes, and having a notch formed at a top portion of the flame distributor and communicated with the mixing chamber; and
a burner cover disposed to the flame distributor, the burner cover being configured to cover the mixing chamber and limit the notch to define an outlet of the mixed gas, thereby forming a flame ring;
wherein the flame distributor comprises two partition structures disposed in the mixing chamber and configured to divide the mixing chamber into two separate sub-chambers, and the two venture tubes are respectively communicated with the two sub-chambers.

2. The burner according to claim 1 , wherein the gas input passage is configured to have a straight line shape, and the flame distributor presents a circular-ring shape, a middle axis of the gas input passage passes through a center axis of the flame distributor, and the two nozzles are respectively disposed at two sides of the center axis of the flame distributor.

3. The burner according to claim 1 , wherein the gas input passage is substantially Y-shaped and comprises two end points, the flame distributor presents a circular-ring shape, a connection line between the two end points passes through a center axis of the flame distributor, and the two nozzles are disposed at the two end points respectively.

4. The burner according to claim 3 , wherein the gas input passage further comprises a connection passage connecting the two end points with each other.

5. The burner according to claim 1 , wherein the two nozzles and the two venturi tubes are vertically disposed.

6. The burner according to claim 1 , wherein the bottom cup comprises two cup portions, the two nozzles are provided in the cup portions respectively, the flame distributor comprises two blocking hems, and the two hems are corresponding to and flush with top edges of the two cup portions respectively, the bottom cup or the flame distributor comprises a spacer configured to space the two blocking hems apart from the top edges of the two cup portions.

7. The burner according to claim 6 , wherein a dimension of the blocking hems is larger than that of the top edges of the bottom cup.

8. The burner according to claim 1 , wherein the venturi tube extend into the cup portion.

9. The burner according to claim 1 , wherein the gas input passage comprises two separate sub-passages, and the two nozzles are respectively disposed to the two separate sub-passages.

10. The burner according to claim 1 , wherein the flame distributor further comprises a partition board with substantially circular ring shape, the partition board is provided with two island portions extending inwards at two ends along a diameter direction of the flame distributor; the two venturi tubes are respectively arranged at the two island portions and configured to pass through the two island portions.
