Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1 to Figure 5 As shown, the gas cooker injector sequentially includes a nozzle 1, an injector pipe 2 and a bracket 3 connecting them along the airflow direction.

[0023] Wherein, the nozzle 1 includes a body 11 and an air flow channel passing through the body 11 along the air flow direction.

[0024] The air flow passage is divided into an air intake section 12, a buffer chamber 14 and at least two air outlet sections 13 in sequence along the air flow direction; there are two air outlet sections 13 in this embodiment, and more can also be provided. The air outlet sections 13 are arranged side by side, the buffer chamber 14 and the inlet section 12 have a circular cross-section, and the sum of the cross-sectional areas of the inlet end surfaces of each inlet section 12

Abstract

The invention relates to an ejector of a gas cooker. The ejector comprises a nozzle and an ejection tube which are sequentially arranged in the airflow direction. The ejection tube comprises a shrinkage part, a mixing part and a diffusion part in the airflow direction according to the change of the cross section. An outlet of the nozzle is opposite to an inlet of the shrinkage part. The nozzle comprises a body and an airflow channel penetrating the body. The ejector is characterized in that the cross section of an airflow channel outlet of the nozzle is a polygon or a Reuleaux polygon and is in a non-circular shape; and the cross section structure of an inner cavity of the mixing part is identical to that of the airflow channel outlet. Compared with the prior art, through the design of the special structure of a nozzle channel and the ejector channel, the ejector of the gas cooker is good in gas pressure fluctuation resistance, and heat losses in a heat state are greatly reduced.

Description

technical field [0001] The invention relates to a gas cooker assembly, in particular to an injector for a combustion cooker. Background technique [0002] The ejector is one of the important components of the burner, which ejects the air in the surrounding environment through the gas flow. The ejector usually includes a nozzle and an ejector pipe, wherein the ejector pipe is divided into a constriction part, a mixing part and a divergence part according to the change of the cross section along the gas flow direction; the nozzle is located upstream of the constriction part, and the nozzle part The outlet faces the inlet of the constriction, that is, the primary air inlet. [0003] In the existing ejector, the nozzle passage and the ejection pipe passage are all circular, and the pressure fluctuation has a great influence on the ejection effect, and the heat load loss is large in the hot state. Contents of the invention [0004] The technical problem to be solved by the pr...
