Technical Field
The invention relates to a household gas stove, in particular to a gas stove nozzle.
Background
The maximum thermal load (power) that a household gas cooker can reach when meeting various indexes of national standards, such as carbon monoxide content, thermal efficiency and the like, is called as the nominal maximum thermal load of the gas cooker. However, the existing household gas stove can only be adjusted within the range of the nominal maximum heat load, and a user of the combustion stove cannot obtain a cooking environment larger than the nominal maximum heat load, which cannot completely meet the requirements of modern household users. Especially, some cooking modes such as quick-frying which need a strong fire to achieve the cooking effect cannot be achieved by a common gas stove. Some gas stoves adopt a double-channel double-nozzle design to increase heat load, and the double nozzles are arranged in parallel, so that gas injection and gas mixing effects are poor, and the installation structures of the nozzles and the inner part of the stove are relatively complex.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 2, 3 and 4, a nozzle holder of a gas stove comprises a holder body 1 formed by winding a metal thin wall, a first gas channel 2 and a second gas channel 3 for providing external fire of a burner of the stove, and a third gas channel 4 and a fourth gas channel 5 for providing central fire of the burner of the stove. The middle of the base body 1 is provided with a hollow hole, one end of the hollow hole can be provided with a fan 7 for providing primary air, and the other end of the hollow hole is opposite to an injection pipe of a burner of the stove. The tail ends of the first gas channel 2 and the second gas channel 3 are coaxial structures, and a first nozzle 81 and a second nozzle 82 of the compound nozzle 8 are correspondingly arranged; the tail ends of the third gas channel 4 and the fourth gas channel 5 are also coaxial structures and are respectively provided with a first nozzle 81 and a second nozzle 82 of the second compound nozzle 8 correspondingly; two compound nozzles 8 are respectively arranged in a hollow hole in the middle of the seat body 1 and are arranged left and right separately, and different hole diameters are arranged according to the designed gas flow. The second fuel gas channel 3 and the fourth fuel gas channel 5 are respectively provided with a flow reducer 9, which is convenient for processing the fuel gas channels and controlling the fuel gas flow.
The second gas channel 3 is provided with a valve 6, and the valve 6 is an electromagnetic valve for controlling whether the second gas channel 3 supplies gas to the second nozzle 82. The fourth gas channel 5 is connected from the second gas channel 3 at the rear end of the valve 6, and the valve 6 can simultaneously control the connection and disconnection of the second gas channel 3 and the fourth gas channel 5. The second gas channel 3 at the front end of the valve 6 can be directly connected with an external gas supply pipe and is in a parallel connection mode with the first gas channel 2, the second gas channel 3 at the front end of the valve 6 of the embodiment is communicated with the first gas channel 2 in a series connection mode, a gas circuit can be connected simply and safely, only one outer ring fire gas pipe and one central fire gas pipe are needed for connection with a gas valve of a gas stove, and the connection with a common stove is free from difference.
