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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0022] As shown in Figures 1, 2 and 3, a single-ejector top-inlet stove burner includes an inner fire cover 1, an outer ring fire cover 2, a burner head 3 and a fire distributor seat 4.

[0023] The burner 3 includes a base plate 31, a nozzle base 321 and an air inlet base 322 provided at the front end of the base plate, a lower front support base 33 with a hollow front opening and an upper opening, a rear support base 34, an ignition pinhole 351, and a sensing pinhole 352. The nozzle base 321 and the air inlet base 322 are in a vertical straight line. The air inlet base 322 is provided with an air inlet interface 3221, and the axis of the air inlet interface 3221 is perpendicular to the axis of the air inlet base 322. The rear wall plate of the front lower support base 33 is provided with a front slot 331 with an upper opening. The rear support base 34 is provided with a middle rear slot 341, a rear left slot 342, and a rear right slot 343. The rear left slot 342 has an upper opening and a left side opening, and the rear right slot 343 has an upper opening and a right side opening, respectively.

[0024] The igniter seat 4 includes an inner fire cover seat 41, an outer ring gas groove 42, a rear air guide cavity 43, an ejector pipe 44, two radial gas channels 45 arranged in the left and right directions, four axial secondary air channels 46, a hollow front upper support seat 47 with a front opening and a lower opening, and a rear latch 48. The air inlet end of the ejector pipe 44 intersects with the rear wall plate of the front upper support seat 47, and a front latch 441 is provided on the front upper support seat 47; the rear latch 48 is provided on both sides of the rear air guide cavity 43; the ejector pipe 44, the rear air guide cavity 43, and the outer ring gas groove 42 are connected in sequence, and the radial gas channel 45 connects the inner fire cover seat 41 and the outer ring gas groove 42; the gas enters the ejector pipe 44 through the nozzle of the nozzle seat 321, enters the outer ring gas groove 42 through the rear air guide cavity 43, and the gas flows in the outer ring gas groove 42 in the clockwise and counterclockwise directions; at the same time, the gas enters the inner fire cover seat 41 through the radial gas channel 45;

[0025] The front lower support seat 33 supports the front upper support seat 47. The front latch 441 engages with the front slot 331. The rear air guide cavity 43 engages with the middle rear slot 341 on the rear support seat 34.
