[0020] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0021] Please refer to Figure 1 to Figure 2 As shown, a carburetor dedicated to a lawn mower of the utility model comprises a body 1, a float chamber 2 and a gas cylinder, wherein the body 1 comprises an air flow channel 11 and an oil suction channel 12, wherein the oil suction channel 12 is vertically arranged at the bottom of the air flow channel 11, and the top of the oil suction channel 12 is connected to the middle of the air flow channel 11;

[0022] The float chamber 2 includes an air inlet nozzle 21, an oil inlet end 22 and an oil outlet end 23. The oil inlet end 22 and the air inlet nozzle 21 are arranged at the top of the float chamber 2. The oil outlet end 23 is arranged at the bottom of the side wall of the float chamber 2. The oil outlet end 23 is communicated with the bottom of the oil suction channel 12.

[0023] The gas cylinder comprises a cylinder body and a cylinder valve. The cylinder body contains pressurized protective gas, and the cylinder valve is detachably connected to the gas inlet nozzle 21.

[0024] From the above description, it can be seen that by setting up an additional gas cylinder and setting the main body 1 and the float chamber 2 into a U-shaped oil inlet structure, the oil outlet end 23 of the float chamber 2 is set at the bottom of the side wall of the float chamber 2 and connected to the oil suction channel 12. When the lawn mower needs to be shut down for a long time, the gas cylinder and the bottle valve connected to the air inlet nozzle 21 are directly opened to release the pressurized gas. The pressurized gas can form an airflow to send the gasoline in the entire float chamber 2 and the residual gasoline in the oil suction channel 12 into the airflow channel 11. In addition, the U-shaped oil inlet structure is used to avoid gasoline residue, ensure clean and rapid discharge of gasoline, and the protective gas can form protection to avoid oxidation and corrosion, thereby extending the service life of the carburetor.

[0025] Furthermore, the body 1 also includes a plunger 13 and a throttle cable, and the throttle cable drives the plunger 13 to move up and down.

[0026] From the above description, it can be seen that the throttle cable drives the plunger 13 to move up and down to open and close the air flow channel 11. The air flow channel 11 can be opened when the gas cylinder is inflated to discharge gasoline to the outside, thereby preventing gasoline from entering the intake manifold or the engine and causing corrosion when the engine is not working.

[0027] Furthermore, a bent tube is provided on the air inlet nozzle 21 .

[0028] It can be seen from the above description that the provision of the bent tube can avoid interference between the air inlet nozzle 21 and the oil inlet end 22 during operation.

[0029] Furthermore, the air inlet nozzle 21 is provided with a connecting hose.

[0030] As can be seen from the above description, by connecting the hose, the direction can be adjusted to facilitate shutdown cleaning.

[0031] Furthermore, force-bearing wings 24 extending outwards are respectively provided on both sides of the air inlet nozzle 21 .

[0032] From the above description, it can be known that, through the arrangement of the force-bearing wings 24, it is possible to facilitate the pressing force of the fingers during inflation, so that one hand can operate and the other hand can pull the throttle cable.

[0033] Furthermore, the distance between the air inlet nozzle 21 and the body 1 is greater than the distance between the oil inlet end 22 and the body 1 .

[0034] From the above description, it can be seen that the distance between the air inlet nozzle 21 and the main body 1 is greater than the distance between the oil inlet end 22 and the main body 1. Since the oil inlet end 22 is not often used and is rarely used after being connected once, it is set in the middle to avoid interference with the main body 1 or the air inlet nozzle 21 during use.

[0035] Furthermore, a temperature insulation layer is provided on the outer periphery of the air inlet nozzle 21 .

[0036] From the above description, it can be seen that by setting up the thermal insulation layer, cold insulation can be achieved, so as to avoid frostbite on the staff caused by the low temperature generated by the expansion of the released compressed gas during inflation.

[0037] Furthermore, the air inlet nozzle 21 and the oil inlet end 22 are coated with coatings of different colors respectively.

[0038] From the above description, it can be seen that different colors can be used to distinguish and avoid wrong connection of pipelines.

[0039] Furthermore, the protective gas is nitrogen or air.

[0040] From the above description, it can be seen that by using nitrogen, the cost is low, the safety is high, and it will not react with the water in the gasoline to produce acid; the cost of air is even lower, and it can be directly inflated with a pump containing a gas cylinder (gas tank); if carbon dioxide is used, it is easy to generate acid, which will cause corrosion to the carburetor, intake manifold, and engine.
