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...

Embodiment Construction

[0079] In the following, the present invention will be more clearly and completely described by means of an embodiment in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiment.

[0080] like Figure 1-3 As shown, an injection joint 100 of this embodiment 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 100 includes an injection section 110, The ejection section 110 has an ejection channel 111 inside, and the two ends of the ejection channel 111 are respectively provided with an ejection port 112 and a gas outlet port 113 along the gas flow direction. The ejection section 110 also has a limiting portion 120, which is arranged at one end of the injection port 112, and the limiting portion 120 is provided with a limiting through hole 121, which is used for inserting and limiting the through hole 121 compatible gas nozzles.
