Problems solved by technology

[0003] The inventors have found that the following problems exist in the prior art: the atmospheric pressure in different regions is different, even if it is the same gas source, the air mixing ratio required for gas source combustion is different, and different air pressures have different requirements for the size of the nozzle aperture. The nozzle cannot change the hole diameter, so that the existing gas stoves cannot meet the requirements of different air pressures

Embodiment 2

[0068] ginseng Figure 13 , The technical solution of this embodiment has the following differences from the technical solutions of the above-mentioned embodiments. In this embodiment, the adjustment member adopts the following structure: the adjustment member 1 is a plate-shaped structure, and the adjustment member 1 is provided with a chute 21 . A groove 71 is provided on the side of the nozzle body 7 . The groove 71 is connected to the gas flow channel 11 . Wherein, the width dimension of the chute 21 is variable, and at least part of the width dimension of the chute 21 is smaller than the inner diameter dimension of the gas flow channel 11 . ID dimensions refer to diameters.

[0069] The flow rate corresponding to at least part of the width dimension of the chute 21 is smaller than the flow rate of the gas flow channel 11, so that after the chute 21 rotates, after the width of the chute 21 communicating with the gas flow channel 11 changes, it flows through the chute 21 ...

Abstract

The invention discloses a gas nozzle and a burner, and relates to the field of cookers. With the gas nozzle and the burner, a gas stove can meet the requirements of combustion of gas sources for different air mixing ratios under different air pressures. The gas nozzle comprises a nozzle body and an adjusting part, wherein the nozzle body is provided with a gas flow pass and an air flow pass which communicates with the gas flow pass all the time, and the adjusting part is used for adjusting the flow area of the gas flow pass. According to the gas nozzle and the burner, on the premise that the air flow pass is unchanged, the flow of the gas flow pass can be changed, so that the combustion ratio between gas and air can be changed. The gas nozzle and the burner can meet the different requirements for gas and air mixing ratios in different areas, and further one gas nozzle can meet the requirements of different gas sources for different fuel and air mixing ratios at the same time.

Description

technical field [0001] The invention relates to the field of cookers, in particular to a gas nozzle and a burner. Background technique [0002] The nozzle is an important part of the stove burner, which is used to provide the air and gas required for combustion. At present, the nozzles are divided into natural gas nozzles and liquefied gas nozzles. At different altitudes, the structures of natural gas nozzles and liquefied gas nozzles are exactly the same. [0003] The inventors have found that the following problems exist in the prior art: the atmospheric pressure in different regions is different, even if it is the same gas source, the air mixing ratio required for gas source combustion is different, and different air pressures have different requirements for the size of the nozzle aperture. The nozzle cannot change the hole diameter, so that the existing gas stoves cannot meet the requirements of different air pressures. Contents of the invention [0004] One of the o...
