Problems solved by technology

Due to its stable flow rate, it is generally the same as the nozzle designed with a round hole. When the air source is ejected from this type of round hole or cylindrical outlet section, the contact area between the air source and the air is small, and the entrainment and injection of air is relatively limited. In order to improve the nozzle's ability to inject primary air, further improvement is required

Embodiment 1

[0066] like Figure 1-14As shown, the nozzle for a gas stove in this embodiment includes a body 1a, the body 1a includes a nozzle portion 2a located at the tail of the body 1a for injecting gas into the body 1a, and a head portion of the body 1a, which is tubular and an air chamber 4a provided in the outlet portion 3a and isolated from the nozzle portion 2a, the air chamber 4a includes a head wall 401a, a tail wall 402a and a peripheral wall 403a connecting the head wall 401a and the tail wall 402a The head of the air chamber 4a has an air outflow hole 41a which is in fluid communication with the outlet portion 3a for primary air to flow out, and the tail wall of the air chamber is isolated from the nozzle portion 2a and has an inner surface of the pipe wall corresponding to the outlet portion 3a An inflow port for the inflow of gas injected into the main body 1a is formed, and the peripheral wall 403a of the air chamber 4a has an air inflow hole 42a in fluid communication wit...

Embodiment 2

[0075] The structure is basically the same as that of Embodiment 1. The only difference is that the cavity 13 is a semi-closed cavity 13 with only the second gap 5 and no air dividing cavity, such as Figure 15 and 16 shown.

Abstract

The invention relates to a nozzle for a gas stove and a gas stove using the nozzle. The nozzle comprises a body, the nozzle is characterized in that the body comprises a nozzle part located at the downstream position of the body so as to allow gas to be sprayed into the body, an outlet part located at the upstream portion of the body, an air chamber and an gas outflow part, the air chamber is arranged in the outlet part and is relatively isolated from the nozzle part, and the air chamber is provided with an air inflow hole in fluid communication with the outlet part and a primary air hole formed in the outer surface of the pipe wall corresponding to the outlet part and communicating with the air inflow hole. Compared with the prior art, the novel nozzle has the advantages that the gas outflow part of the nozzle is located at the periphery of the outlet part, and the air chamber allowing primary air to enter independently is arranged at the inner periphery of the outlet part, so that gas and the primary air are promoted to be rapidly mixed in front of the outlet part of the nozzle, and then the nozzle is provided with an inner channel air injection structure and an outer channel airinjection structure.

Description

technical field [0001] The invention relates to the field of household kitchen utensils, and in particular, the invention relates to a nozzle for a gas stove and a gas stove using the nozzle. Background technique [0002] Most of the existing stove burners on the market are atmospheric burners, which need to premix part of the primary air in advance, which requires a damper opening size adjustment device to adjust the required amount of premixed primary air. As disclosed in Chinese patent CN201220400855.X, "a kind of ejector gas ignition device" includes a combustion cylinder with an air inlet or a combustion cylinder equipped with an ignition gun, and the combustion cylinder with an air inlet or a combustion cylinder equipped with a point The rear end of the combustion cylinder of the fire gun is connected with a mixing cylinder, the connection between the mixing cylinder and the combustion cylinder with the air inlet is a straight-through coaxial connection, and the connec...
