An outer ring burner cap and a gas stove

Abstract

An outer ring burner cap and a gas stove are disclosed. The outer ring burner cap includes a cylindrical main body, an annular top plate, and several combustion chambers disposed on the annular top plate. The gap between two adjacent combustion chambers forms a secondary air groove. A first combustion hole group is provided on the outer circumferential surface of the combustion chamber, and a second combustion hole group is provided on the wall plate on the starting side in a clockwise direction. The arrangement of the combustion chambers ensures uniform gas distribution. During combustion, secondary air surrounds the combustion chamber, resulting in complete combustion, high energy efficiency, and the ability to achieve high power.

Description

Technical Field

[0001] This utility model relates to a stove burner, and more particularly to an outer ring flame cap for a burner. Background Technology

[0002] The existing technology, Chinese Patent 201920057352.9, describes a burner with an internally mounted ignition needle and thermocouple, comprising a burner body, a connector, a flame cap seat, an outer ring flame cap seat, an outer ring flame cap, and an inner ring flame cap. The burner body has a first air inlet chamber and a second air inlet chamber. An ignition needle and a thermocouple are mounted on the burner body. The working ends of the ignition needle and thermocouple are located below the outer ring flame cap. The flame cap seat is installed at the upper end of the burner body. The upper end face of the flame cap seat is connected to the outer ring flame cap seat via the connector. The outer ring flame cap is installed at the end of the outer ring flame cap seat. The inner ring flame cap is located within the ring of the outer ring flame cap and is connected to the outer ring flame cap seat. The inner ring flame cap has uniformly distributed first flame holes. The air inlet of the first air inlet chamber is connected to a first ejector tube. The air inlet of the second air inlet chamber is connected to a second ejector tube. The problem is that the outer ring burner cap has outer ring combustion holes distributed on the circumference at the upper part of its outer circumference surface; the density of the outer ring combustion holes is high, resulting in insufficient secondary air and low power. Utility Model Content

[0003] The purpose of this invention is to provide an outer ring burner cap that has several combustion chambers, sufficient secondary air, and high power.

[0004] This utility model is implemented as follows: an outer ring flame cap, which is special in that it includes a cylindrical main body, a circular annular top plate and several combustion chambers provided on the circular annular top plate, and the gap between two adjacent combustion chambers forms a secondary air groove.

[0005] The outer circumferential surface of the combustion chamber is provided with a first set of combustion holes, and the wall plate on the starting side in the clockwise direction is provided with a second set of combustion holes.

[0006] The outer ring flame cap is characterized in that the combustion chamber rotates to the left or right.

[0007] The outer ring flame cap is characterized in that the second combustion hole group includes a large circular hole group and a small circular hole group, which are arranged vertically and vertically, with the large circular holes of the large circular hole group and the small circular holes of the small circular hole group alternating.

[0008] The outer ring flame cap is characterized in that the volume of the combustion chamber gradually decreases from bottom to top.

[0009] The outer ring flame cap is characterized in that the width of the combustion chamber gradually increases from the radial side to the outer radial side.

[0010] The outer ring flame cap is characterized in that: the outer peripheral surface of the combustion chamber is shaped like a frustum of a cone, the wall plate on the starting side in the clockwise direction is shaped like a frustum of a cone, and the ending side in the clockwise direction is a concave frustum of a cone curved surface.

[0011] A gas stove, characterized by including an outer ring burner cap as described above.

[0012] This utility model discloses an outer ring burner cap, and the combustion chamber is designed to ensure uniform gas distribution. During combustion, secondary air surrounds the combustion chamber, resulting in complete combustion, high energy efficiency, and the ability to achieve high power. Attached Figure Description

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, an outer ring flame cap includes a cylindrical main body 1, an annular top plate 2, and a plurality of combustion chambers 3 disposed on the annular top plate. The gap between two adjacent combustion chambers 3 forms a secondary air groove 4.

[0020] The outer peripheral surface of the combustion chamber 3 is provided with a first combustion hole group 31, and the wall plate on the starting side in the clockwise direction is provided with a second combustion hole group 32.

[0021] As a further improvement to this utility model: such as Figure 1 , Figure 3 As shown, the annular top plate 2 is in the shape of an inverted frustum cone, and the combustion chamber 3 is left-handed; the combustion chamber 3 can also be right-handed.

[0022] The volume of the combustion chamber 3 gradually decreases from bottom to top.
