Pipe Lighter Fire Outlet Hood for Sequential Ignition Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighters face issues of operation inconvenience due to size limitations, difficulty in pressing ignition, and low ignition rates caused by simultaneous operation of ignition and gas release, leading to potential scalding and fire insulation.
Innovation Solution
A tobacco pipe lighter design featuring a slidable toggle member with a toggle plate and elastic member for delayed ignition, a fire outlet hood linked to the ignition mechanism, and a transmission component for smooth operation, allowing the fire outlet hood to protrude and jet out flame safely, with a windshield for flame control and a tobacco pipe for convenient tobacco storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pressing part is closer to the fuel port to achieve pressing ignition, then the ignition function is achieved, but the risk of scald increases
Solution Approach 1:
The lighter is divided into separate functional modules: the ignition mechanism (pressing part) is separated from the fuel port by the fire outlet hood structure. When the ignition button is pressed, the fire outlet hood extends outward to position the flame away from the user's fingers, while the fuel port remains in its original position. This spatial segmentation resolves the contradiction between easy ignition operation and scald prevention.
2Volume of moving object
If the ignition switch is made small to reduce lighter size, then the lighter is compact, but it is difficult and laborious to press
Solution Approach 1:
The pressing force is transferred from a small vertical button press to a larger horizontal sliding motion of the fire outlet hood. The ignition button remains small for compactness, but the fire outlet hood provides a larger surface area that can be pushed horizontally, distributing the force requirement over a larger area and making it easier to operate while maintaining a compact overall lighter design.
3Speed
If the ignition member and gas release member work at the same time, then ignition is achieved quickly, but fire insulation occurs and ignition rate is low
Solution Approach 1:
The mechanism is designed so that when the ignition button is pressed, the fire outlet hood extends outward first, creating a clear path for the flame. Only after the hood is in position does the ignition member generate the spark. This preliminary action of positioning the flame outlet before ignition prevents fire insulation and ensures high ignition rate, while still achieving quick overall ignition.
4Shape
If the fire outlet hood is hidden in the shell, then the lighter has a compact appearance, but the flame cannot be jetted out safely
Solution Approach 1:
The fire outlet hood is designed as a dynamic component that can extend outward when the ignition button is pressed and retract when not in use. In the retracted state, the hood is hidden within the shell, providing a compact and aesthetically pleasing appearance. When ignition is needed, the hood extends outward to position the flame away from the user's fingers, eliminating the scalding hazard. This dynamic transformation resolves the contradiction between compact appearance and safe flame jetting.

Function Achieved in This Case
The design ensures safer and more efficient ignition by avoiding scalding, reducing the lighter's thickness, and enhancing ignition reliability through sequential operation of release and ignition components, thus improving usability and reducing fire insulation risks.

AI summary
The present application discloses a tobacco pipe lighter, and relates to the technical field of lighters. The tobacco pipe lighter includes a shell, an ignition mechanism linked with a toggle member slidably disposed on the shell, a fire outlet hood hidden in the shell and linked with the ignition mechanism, and a tobacco pipe juxtaposed with the fire outlet hood and used for storing cut tobacco, wherein the ignition mechanism includes an ignition member, a swing member and an elastic member, and when the toggle member toggles, a release member cooperates with the ignition member to perform ignition while the swing member pushes the fire outlet hood out of the shell, and a flame is jet out of the fire outlet hood. The present application is not only safe in use and small, but also can avoid fire insulation, thereby increasing the ignition rate.
