Device for detecting and adjusting gas outlet flow of lighter

Abstract

The invention relates to a device for detecting and adjusting gas outlet flow of a lighter, which solves the technical problem the adjusting nut of the lighter is difficult to adjust at present. The device for detecting and adjusting the gas outlet flow of the lighter comprises a ventilation shaft, a clamp fixing seat and a clamp adjustment piece which are sleeved on the ventilation shaft, and two splints symmetrically arranged on two sides of the clamp fixing seat; the clamp fixing seat is fixed on the ventilation shaft; the middle part of each splint is coupled to the lower part of the clamp fixing seat through a positioning pin; an adjustment hole is formed upward and inward on the upper part of each splint; a movable pin passes through the adjustment hole to connect the upper parts of the splints to the clamp adjustment piece; a clamp port is formed on the inner side of the bottom of each splint; a gas guide passage positioned above the clamp port is formed in the center of the ventilation shaft; and a flow detector is connected with the upper end of the gas guide passage. Compared with the conventional method for directly detecting the height of the flame, a method for adjusting the height of flame by detecting and adjusting the gas outlet flow of a gas outlet needle is more accurate and quicker.

Description

technical field [0001] The invention relates to a lighter detection and adjustment device, in particular to a lighter outlet gas flow detection and adjustment device. 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 or less within 5 seconds after ig...

Problems solved by technology

This device needs to sense the flame through the thermocouple, so it needs to design a complex circuit structure, and the thermocouple needs to be maintained frequently to prevent the sensitivity of the thermocouple from degrading

In addition, the above measuring devices all need to ignite the lighter and then measure the flame. Only the lighter with no plastic parts in the flame involved after the lighter is ignited can be tested, otherwise the flame will melt the plastic parts, which is greatly affected by the structure of the lighter itself. It is suitable for testing some models; it has high requirements for the testing environment (such as windproof); after measuring the flame height, the lighters that do not meet the requirements are screened out, and then the adjustment is still done manually, without synchronous adjustment after the test. Repeated testing is required, and the efficiency is low
