Injection joints, injection tubes, burners and gas stoves

Abstract

The invention discloses an injection joint, an injection pipe, a burner and a gas stove. The injection joint is used to connect with the gas mixing section of the injection pipe and can be offset relative to the gas mixing section. The injection joint includes an injection Injection section, there is an injection channel in the injection section, and the two ends of the injection channel have injection ports and gas outlets respectively along the gas flow direction; there is also a limiter on the injection section, and the limiter is located at the injection port One end of the limiting part is provided with a limiting through hole, and the limiting through hole is used for inserting a gas nozzle matched with the limiting through hole. The injection pipe of the present invention adopts the above-mentioned structure, without setting the aperture diameter of the limiting through hole to be much larger than the outer diameter of the gas nozzle, so that the aperture of the limiting through hole can be just adapted to the outer diameter of the gas nozzle. It can prevent the gas from colliding with the inner wall of the injection channel when the gas is ejected, causing irregular and violent movement of the gas flow to affect the injection of the outside air, and ensuring that the injected gas can normally inject the air.

Description

technical field [0001] The invention relates to the field of cooking utensils, in particular to an ejection joint, an ejection pipe, a burner and a gas stove. Background technique [0002] When the burner burns, it needs to mix the gas and air to form a mixed gas. Therefore, when the gas enters the burner, a part of the air will be injected through the injection tube for mixing. The amount of mixed air in the gas will affect the combustion rate and thermal efficiency of the gas. If the amount of air mixed in the gas is too small, the gas will not be fully combusted, and yellow flames and pollutants will easily be generated. If it is too much, the gas will be diluted. The ratio can not meet the heat required for heating the pot, and the thermal efficiency is low. Therefore, a baffle is usually arranged at the injection port of the injection tube, and there is a tuyere on the baffle, and the size of the tuyere is adjusted through the damper to control the amount of air enteri...

Problems solved by technology

However, for the in-line valve nozzle, due to its structural limitation, it cannot be fixed with the injection tube in advance. Generally, the position of the injection tube is fixed, and then the nozzle is inserted into the injection tube of the injection tube when installing the nozzle. In the mouth

In order to facilitate the installation of the in-line valve nozzle and insert the nozzle into the injection port, a hole with a diameter larger than the outer diameter of the gas nozzle will be set on the partition plate. The eccentricity causes the injected gas to hit the inner wall of the cavity of the ejection section, thus affecting the ejection of the outside air
