Embodiment Construction

[0053] In the following, the present invention will be more clearly and completely described by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the described embodiments.

[0054] Such as Figure 1-Figure 6As shown, the present invention discloses an injection tube 1, which includes a pipeline body, the pipeline body is formed by a coaxial inner tube 11 and an outer tube 12, and the annular gap between the inner tube 11 and the outer tube 12 The ejection structure of the ejection tube 1 is formed.

[0055] Compared with the traditional circular, elliptical or other arc-shaped injection tubes 1, the injection tube 1 of this embodiment is formed by coaxial inner tube 11 and outer tube 12, and the inner tube 11 and the outer tube 12 are used. The annular gap between the outer tubes 12 is used as the injection structure of the injection tube 1, and the annular gap can have more inner wall circumference whe...

Abstract

The invention discloses an ejection pipe and a cooker burner comprising the same. The ejection pipe comprises a pipe body. The pipe body is composed of an inner pipe and an outer pipe which are sleeved coaxially. An annular gap between the inner pipe and the outer pipe forms an ejection structure of the ejection structure. The cooker burner comprises a gas nozzle assembly, the above ejection pipeand a base which are arranged in the gas flow direction in sequence. One end of the ejection pipe is connected to the base. The other end of the ejection pipe is provided with the gas nozzle assembly.The ejection pipe are formed by coaxially sleeving the inner pipe and the outer pipe. The annular gap between the inner pipe and the outer pipe serves as the ejection structure of the ejection pipe.Under the condition of occupying the same cross sectional area, the annular gap can have the more inner wall perimeter. Through the structure, the area of the inner wall of the ejection pipe can be effectively increased. Accordingly, more air can be sucked under the condition of the same surface pressure of the inner wall, and the ejection effect of the ejection pipe on the air is improved.

Description

technical field [0001] The invention relates to an injection pipe and a cooker burner containing the same. Background technique [0002] The ejector tube is an important part of the cooker burner. The ejector receives the gas from the nozzle, uses the pressure difference generated by the gas flow in the ejector tube to suck in the surrounding air, and finally sends the gas and air into the gas mixing chamber, so that the gas It is fully mixed with air, so that the mixed gas is fully burned at the gas hole, and the combustion efficiency of the stove burner is improved. [0003] The cross-sectional shape of most injection pipes is usually circular or elliptical, which can be divided into constriction section, horizontal section and expansion section according to the change of cross section along the direction of gas flow. Wherein, the existing ejection tube has poor ejection ability to air, which directly affects the combustion effect of the cooker. Therefore, how to improve...
