Method and device for detecting and adjusting flame height of lighter

Abstract

The invention provides a method and device for detecting and adjusting flame height of a lighter, belonging to the field of detection equipment of lighters. The invention solves the problems that the current detection and adjustment of the flame height of the lighters have low measuring accuracy or low requirements for the detection environment and the like. The method for detecting and adjusting the flame height of the lighter comprises the following steps: A, detection: detecting the outlet gas flow of a gas outlet needle of the lighter through a flow sensor and transducing flow analog signals to a controller; B, comparison: in the controller, converting the flow analog signals into outlet gas flow values and comparing with a set value to generate a comparison difference; and C, adjustment: in the controller, converting the comparison difference into control analog signals and transmitting to a controllable motor so that the controllable motor drives an adjusting nut to rotate a corresponding angle, thereby finishing correction and adjustment once. The method is accurate and quick, has low requirements for the outside environment, can adjust the adjusting nut of the lighter through the controllable motor in real time, and improves the efficiency.

Description

technical field [0001] The invention belongs to the technical field of lighter detection, and in particular relates to a detection and adjustment method and device for the flame height of a lighter. Background technique [0002] As a dangerous product, the flame height of the lighter is a necessary inspection item in the production process. According to the provisions of my country's entry-exit inspection and quarantine industry standards for the inspection of dangerous goods for export lighters, the qualification criteria for the flame height of lighters is: for lighters with flame height regulators, 98% of the test samples should meet the requirements. At the maximum flame position, the flame height is 150 mm or less within 5 seconds after ignition; when the flame height regulator is at the minimum flame position, the flame height is 50 mm or less within 5 seconds after ignition; For lighters, 98% of the test samples should meet the requirements. The flame height is 50 mm o...
