Description

Technical Field

[0001] This invention relates to the field of lighter technology, and more particularly to a lighter. Background Technology

[0002] Existing lighters typically only function normally at room temperature. When the ambient temperature drops to -5°C, the ignition rate of direct-fire lighters is very poor, ignition is difficult, and extinguishing is slow. At room temperature, the flame height of a lighter is 1.5-2cm, but when the ambient temperature reaches 45°C, direct-fire lighters become difficult to ignite due to the force of the flame. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention proposes a lighter.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design a lighter, including a body, the body having a gas storage chamber containing combustible gas; the body having a gas outlet valve assembly, the gas outlet valve assembly including a valve body fixedly installed in the body, the valve body having a valve hole, a cotton pad being placed in the valve hole via a pin seat; a screw plug being threaded to the upper end of the valve hole, a gas outlet needle extending upward from the screw plug being disposed between the screw plug and the cotton pad in the valve hole, a gas outlet spring being sleeved on the gas outlet needle to force the gas outlet needle to move downward, and a sealing ring being sleeved on the outer side of the gas outlet needle above the gas outlet spring. The machine body has a gasification furnace fixedly installed at the upper end of the gas outlet needle. A silver sheet is installed inside the gasification furnace at the gas outlet port at the upper end of the gas outlet needle. The cotton sheet meets the following requirements: the weight of 100 cotton sheets is 67g-69g; the diameter of the air holes in the silver sheet is 0.67mm-0.69mm; the wire diameter of the gas outlet spring is 0.42mm; an exhaust groove is provided on the outer side of the gas outlet needle at the contact position with the sealing ring. When the gas outlet needle is in the downward closed position, the exhaust groove connects the inner hole of the screw plug to the atmosphere; the combustible gas is a mixture of propane, ethylbutane, and n-butane.

[0005] In a further technical solution, the exhaust grooves are two in number and symmetrically arranged on the outer circumference of the exhaust needle.

[0006] In a further technical solution, the silver sheet is made of stainless steel.

[0007] In a further technical solution, the combustible gas contains 25%-35% propane by volume, 45%-55% ethylbutane by volume, and 10%-30% n-butane by volume.

[0008] In a further technical solution, a collar is provided inside the gasifier, the collar is sleeved on the outer side of the upper end of the gas outlet needle, and the silver sheet is disposed at the upper end of the collar.

[0009] The lighter proposed in this invention has the following advantages: by changing the density of the cotton pad, the diameter of the air hole in the silver sheet, the wire diameter of the gas spring, setting an exhaust groove on the outside of the gas needle near the sealing ring, and the composition of the combustible gas, the lighter can achieve normal ignition and a stable flame with quick extinguishing in ambient temperatures as low as -5℃ or as high as 45℃.

Detailed Implementation

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0012] like Figure 1-5 The lighter shown includes a body 1, a gas storage chamber 1a containing combustible gas 14, and a gas outlet valve assembly. The gas outlet valve assembly includes a valve body 2 fixedly installed inside the body 1, a valve hole 2a inside the valve body 2a, and a cotton pad 4 disposed inside the valve hole 2a via a nail seat 3. A screw plug 5 is threaded to the upper end of the valve hole 2a. A gas outlet needle 6 extending upward from the screw plug 5 is disposed inside the valve hole 2a between the screw plug 5 and the cotton pad 4. A gas outlet spring 7 for forcing the gas outlet needle 6 to move downward is sleeved on the gas outlet needle 6 inside the valve hole 2a. A sealing ring 11 is sleeved on the outer side of the gas outlet needle 6 at the upper end of the gas outlet spring 7. A vaporizer 8 is fixedly installed on the upper end of the gas outlet needle 6 in the body 1. A silver sheet 10 made of stainless steel is disposed at the gas outlet of the upper end of the gas outlet needle 6 in the vaporizer 8. The specific arrangement of the silver sheet 10 is as follows: the gasifier 8 is provided with a collar 9, which is sleeved on the outer side of the upper end of the gas outlet needle 6, and the silver sheet 10 is set on the upper end of the collar 9.

[0013] The cotton pads described in this embodiment meet the following requirements: the weight of 100 cotton pads 4 is 67g-69g; the weight of the cotton pads 4 here is smaller than that of cotton pads in the prior art, which can accelerate the gas release speed of combustible gas and ensure that the gas release is not affected when the operating environment is as low as -5℃ or as high as 45℃. The diameter of the pores in the silver sheet 10 is 0.67mm-0.69mm. This smaller diameter compared to existing silver sheet pores reduces the amount of combustible gas emitted, preventing the lighter from failing to ignite when the flame is too small. For example, in normal temperature conditions, the lighter can still ignite when the flame is reduced to 3mm. However, in temperatures as low as -5℃ or as high as 45℃, even without reducing the pore diameter, the lighter will fail to ignite. By reducing the pore diameter, ignition can be controlled. Furthermore, reducing the pore diameter allows for a higher gas pressure at a given gas output, enabling the flame to be elongated and thinned to ensure proper ignition.

[0014] The gas spring 7 has a wire diameter of 0.42mm; this wire diameter is thicker than that of gas springs in the prior art, allowing the gas needle to quickly return to its original position when the pry bar is released, ensuring the lighter extinguishes quickly. Two vent grooves 6a are symmetrically provided on the outer circumference of the gas needle 6 at the contact point with the sealing ring 11. When the gas needle 6 is in the downward closed position, the vent grooves 6a connect the inner hole of the screw plug 5 to the atmosphere, allowing the combustible gas in the inner hole of the screw plug 5 to be quickly discharged, ensuring the lighter extinguishes quickly. When the gas needle 6 is in the upward open position, the vent grooves 6a disconnect from the inner hole of the screw plug 5. The combustible gas 14 is a mixture of propane, ethylbutane, and n-butane.

[0015] In this embodiment, the volume percentage of propane in the combustible gas 14 is 25%-35%, the volume percentage of ethylbutane is 45%-55%, and the volume percentage of n-butane is 10%-30%.

[0016] The performance testing standards for lighters are as follows: 1. The flame must be able to ignite; 2. The ignition rate must be greater than or equal to 80% (meaning it can ignite 8 or more times out of 10 attempts); 3. The extinguishing time must be less than 3 seconds.

[0017] The performance of the lighter using the above embodiment was tested at an ambient temperature of -5°C, and the performance results are shown in Table 1: Table 1

[0018] The performance of the lighter using the above embodiment was tested at an ambient temperature of 45°C, and the performance results are shown in Table 2: Table 2

[0019] Therefore, it can be seen that by changing the density of the cotton pad, the diameter of the air hole in the silver sheet 10, the wire diameter of the air spring 7, the air vent groove 6a set on the outside of the air needle 6 near the sealing ring 11, and the composition of the combustible gas 14, the present invention can enable the lighter to ignite normally and have a stable flame and fast extinguishing in ambient temperatures as low as -5℃ or as high as 45℃.

[0020] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
