Embodiment 1

[0054] Such as figure 1 As shown, the present invention provides a cooker burner, which includes a base 1 , a fire cover 2 and an injection pipe 3 . Wherein, the fire cover 2 is covered at the upper end surface of the base 1, so that the base 1 and the fire cover 2 jointly enclose a gas mixing chamber, and the outlet end of the ejector pipe 3 is connected to the base 1, so that the fuel gas nozzle (Fig. The injected gas is shown in the figure) to deliver the injected primary air to the air mixing chamber.

[0055] Wherein, the specific structure of the injection tube 3 in the present embodiment 1 is as follows: figure 2 As shown, the injection tube 3 includes a tube body 31 and a flexible member 32 disposed inside the tube body 31 . The pipe body 31 includes a constriction section 31a, a horizontal section 31b and a diffuser section along the gas flow direction A, wherein the diameter of the constriction section 31a gradually decreases, the diameter of the horizontal sectio...

Embodiment 2

[0061] This embodiment provides an injection tube 3, the structure of which is roughly the same as that of the injection tube 3 in Embodiment 1, the difference is that in this embodiment, as Figure 4 with Figure 5 As shown, the horizontal section 31b of the pipe body 31 includes a first pipe section 311 and a second pipe section 312, the first pipe section 311 and the second pipe section 312 are detachably connected to each other along the gas flow direction A, and one end of the flexible member 32 is arranged on the first At the junction of the pipe section 311 and the second pipe section 312, the first pipe section 311 and the second pipe section 312 jointly clamp and position the flexible member 32 so as to be fixedly positioned by the relative combination of the first pipe section 311 and the second pipe section 312 The end surface of the flexible piece 32 achieves the purpose of reliably positioning the flexible piece 32 on the pipe body 31 .

[0062] In addition, ther...

Embodiment 3

[0067] This embodiment provides an injection tube 3 whose structure is substantially the same as that of the injection tube 3 in Example 2, the difference is that in this embodiment, as Image 6 As shown, the connection between the pressure plate 33 and the pipe body 31 in this embodiment is through a flange. At the same time, the first pipe section 311 and the second pipe section 312 of the pipe body 31 are also connected by flanges, so that the pressing plate 33 is relative to the pipe body 31, or the first pipe section 311 is relative to the second pipe section 312 without further relative rotation. The connection is fixed, which is convenient for installation and maintenance.

Abstract

The invention discloses an injection pipe and a cooker burner containing the same, which includes a pipe body, the pipe body includes at least a contraction section and a horizontal section along the gas flow direction, the injection pipe also includes a flexible part, and the flexible part It is arranged on the inner wall of the pipe of the pipe body, there is a gap between the flexible member and the inner wall of the pipe, and the flexible member covers at least the constricted section and the horizontal section adjacent to the horizontal section along the circumferential direction of the pipe body. In the area connected to the constriction section, the flexible member can be deformed under the action of external force, and the flexible member is positioned on the pipe body along the gas flow direction. In the injection pipe, a flexible part is arranged on the inner wall of the pipe between the contraction section and the horizontal section of the pipe body, so that the overall flow rate in the injection pipe is improved in a state of high fire.

Description

technical field [0001] The invention relates to the field of gas cooking ranges, in particular to an injection tube and a cooking range burner containing the same. Background technique [0002] In the current gas cooker, gas is supplied to the ejection pipe through a gas nozzle, and the air around the ejection pipe is ejected as primary air. When the firepower of the gas cooker is small, the gas flow supplied by the gas nozzle is small. Compared with the gas flow, the diameter of the injection pipe is relatively large, which is difficult to meet the demand for air injection under the low gas flow, which will affect the cooker. normal combustion. When the firepower of the gas cooker is small, the gas flow supplied by the gas nozzle is relatively large. Compared with the gas flow, the diameter of the injection pipe is relatively small, which limits the overall flow of gas and air flowing in the injection pipe, and also affects the gas flow of the cooker. Burn normally. Con...
