Lever type safety lighter

Abstract

The invention provides a lever-type safety lighter, which comprises a main body, a hood, a grinding wheel, a fire cap and a lever; wherein, the main body is a hollow body used to fill liquid gas, a closed part is fixed at the top end of the main body; and the closed part is provided with a burner port, wherein, the burner port is provided with a neck; the hood is sheathed at the corresponding upper part of the closed part, wherein, the center of the hood is provided with a fixed seat to hold a flint, two vertical grinding wheel seats facing each other protrude out of the two sides of the hood, and a fixing hole is arranged at the top end of each of the grinding wheel seats; an axial tooth row is arranged at the periphery of each of the grinding wheels; the fire cap is clasped in the hood; the lever consists of a base, a fitting hole, a pressing part and a pivot; a stress arm S2 of the lever-type safety lighter is smaller than an anti-stress arm S1, the mechanical advantage is lower than 1, that is, the stress P is greater than the anti-stress Q, therefore, the lever requires more force rather than saving force. But the rotating force of the lighter is still within the accessible range of force of common users, the mechanical advantages is between 0.3 and 0.8, therefore, the use safety of the lighter is improved.

Description

technical field [0001] The present invention relates to a lever-type safety lighter, in particular to a lever-type safety lighter, which utilizes that the force application arm is smaller than the resistance arm to make the mechanical benefit less than 1, and the application force is greater than the resistance force, so that it is not easy for children to apply force and The lighter is played with the toggle ignition, but it is still within the range of the general user's power, and its mechanical benefit value is between 0.3 and 0.8, so as to achieve the safety of the lighter. Background technique [0002] Simple lighters bring considerable convenience and cost reduction to consumers, which can be regarded as a major breakthrough in the history of modern material civilization since human beings knew how to use fire thousands of years ago. A big worry, especially when young children play with lighters, is likely to cause a fire. The so-called "a single spark can start a pra...

AI Technical Summary

Problems solved by technology

Because the lever can save labor and make it easy to ignite, children often cause fires by playing with lighters without any sense of crisis. This is the shortcoming of the simple lever lighters that have been seen.
