[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, a gas combustion device includes a housing 1, a fire bar 2, a gas valve 3, a discharge needle 4 and a sensing needle 5.

[0024] The housing 1 includes a bottom combustion chamber 11, a side air guide plate 111, a fire row chamber 12 arranged on one side, and a top gathering chamber 13. The bottom combustion chamber 11 is provided with a bottom air inlet 112 at one end and an air outlet slot 113 at the other end. The side air guide plate 111 is provided on a side adjacent to the bottom air inlet 112 and the fire row chamber 12. The top gathering chamber 13 is provided with a top air inlet 131 at one end and a top air outlet 132 at the other end. A top air guide plate 1311 is provided at the bottom of the top air inlet 131, and the top air outlet 132 is connected to the air outlet slot 113. A through hole 121 is provided at one end of the fire row chamber 12. The top air guide plate 1311 allows the flame to enter the top of the top gathering chamber 13 to prevent the flame from directly heating the wall panel of the top gathering chamber and reducing the temperature rise.

[0025] The gas valve 3 is provided with a nozzle arranged longitudinally. In this embodiment, two nozzles are provided, and three or more nozzles may also be provided.

[0026] The fire bar 2 is stacked up and down in the fire bar cavity 12, with the combustion end facing the bottom combustion cavity 11, the ejector pipe 211 of the fire bar 2 is connected to the through hole, the gas valve 3 is arranged at one end of the shell, and the nozzle is facing the ejector pipe 21; the discharge needle 4 and the induction needle 5 are fixed to the end plate of the shell 1, and the ends of the discharge needle 4 and the induction needle 5 match the fire bar 2.

[0027] As a further improvement of the present utility model: the top air guide plate 1311 has a rising angle from the air inlet end to the air outlet end of the shell 1.

[0028] As a further improvement of the present invention, the extension line of the suspended end of the side air guide plate 111 intersects with the wall plate of the shell 1 opposite to the fire row cavity 12. With such a design, firstly, the wind is prevented from blowing directly to the flame, and secondly, an air wall is formed on the wall plate of the bottom combustion cavity, and the air wall is opposite to the flame, thereby improving the thermal efficiency.

[0029] As a further improvement of the utility model: the top gathering cavity 13 is a right-angle trapezoid, and the side of the fire row cavity 12 of the top gathering cavity 13 is a waist plate 13A.
