However, the current regulating oil needle does not have a self-locking structure. After the axial position of the regulating oil needle is adjusted, the regulating oil needle will move axially under the action of oil pressure, resulting in an abnormal change in the fuel flow area, thereby reducing the fuel flow. Adjust the oil needle and the reliability of the carburetor

The invention provides a flow regulating structure for a carburetor and a carburetor with the same. The flow regulating structure for the carburetor comprises a base body, a regulating pin and a locking device, wherein the base body is provided with an installation through hole; the regulating pin is provided with a flow regulating end and an operating end which are correspondingly arranged in the axial direction of the installation through hole, the regulating pin is arranged in the installation through hole in a penetrating manner and is movably arranged relative to the base body in the axial direction of the installation through hole, the outer circumferential surface of the regulating pin is provided with an installation hole, and the flow regulating end is provided with a stretching state of stretching out of the installation through hole; the locking device is arranged in the installation hole and comprises a locking ball and an elastic piece which is pressed against the locking ball and applies acting force towards the hole wall of the installation through hole to the locking ball, the hole wall of the installation through hole is provided with a plurality of spaced locking grooves for containing the locking ball, and the locking ball is provided with a locking state of stretching into any locking groove and an unlocking state of being removed out of the locking groove. The technical scheme provided by the invention is higher in reliability.
Description
technical field [0001] The invention relates to the technical field of vaporization devices, in particular to a flow regulating structure for a vaporizer and a vaporizer having the same. Background technique [0002] The carburetor is the fuel supply device of the gasoline engine. The carburetor is equipped with a fuel quantity regulating oil needle. By changing the position of the regulating needle, the fuel supply quantity can be changed to ensure the stable operation of the engine and improve the starting performance of the engine. As the axial position of the regulating oil needle changes, the fuel flow area formed by the regulating oil needle and the oil channel will change accordingly, thereby changing the fuel supply amount. However, the current regulating oil needle does not have a self-locking structure. After the axial position of the regulating oil needle is adjusted, the regulating oil needle will move axially under the action of oil pressure, resulting in an abn...
