Problems solved by technology

However, in the ejector tubes in the prior art, the air supply volume is not directly proportional to the gas flow rate. When the fire adjustment reaches a certain value, abnormal combustion such as yellow flames will occur due to insufficient air supply.
[0005] Therefore, how to solve the problem that the air supply rate in the prior art cannot adapt to the change of the flow rate of the gas has become an important technical problem to be solved by those skilled in the art

Abstract

The invention discloses an ejecting pipe and a gas combustion device. The ejecting pipe comprises a gas guide channel and an air guide channel; an airflow driving mechanism for accelerating the flowing speed of air is arranged in the air guide channel; and the airflow driving mechanism accelerates the flowing speed of the air to be directly proportional to the flowing speed of gas in the gas guide channel. Through the settings of the ejecting pipe provided by the invention, the air supply is increased along with increment of the flowing speed of the gas, so that such problems as yellow flame caused by insufficient air supply are prevented.

Description

technical field [0001] The invention relates to the technical field of gas combustion equipment, and more specifically, to an injection pipe and a gas combustion device. Background technique [0002] The combustion efficiency of gas combustion devices such as gas stoves and gas heaters is an important factor affecting their quality. Gas combustion devices usually include an injection tube, and the injection tube is one of the main components that affect the combustion efficiency of a gas combustion device. [0003] For example, the burner head of an existing gas stove includes an ejector pipe, an air regulating plate, a damper, an air mixing chamber, etc., wherein the damper is fixed at the end of the ejector pipe. The working principle of the burner head of the gas stove is: open the valve body assembly, the gas flows out from the nozzle at a certain flow rate under a certain pressure, enters the ejector pipe, and at the same time inhales air once, and the amount of air can...
