Description

Technical Field

[0001] This application relates to the technical field of ignition devices, and in particular to a lighter. Background Technology

[0002] Lighters are the most common ignition devices in daily life. They generally achieve electric ignition through the interaction of a gas valve assembly and a piezoelectric structure. To better control the flame, lighters typically have a vaporizer (the part where the chemical reaction directly produces the flame) at the top. The top of the vaporizer has a flame outlet, through which the flame overflows for the user. To secure the vaporizer, a retaining sleeve is usually fitted around its exterior. However, with continuous use, this retaining sleeve wears down, placing extremely high demands on the fire resistance of the retaining sleeve in modern lighters. This results in higher material costs and poses a safety hazard due to high-temperature wear. Utility Model Content

[0003] In order to reduce the material cost of the fixing sleeve and reduce the safety hazards of the lighter itself, this application provides a lighter.

[0004] This application provides a lighter that adopts the following technical solution: A lighter includes a housing, a gas valve assembly disposed within the housing, a piezoelectric component, a vaporizer, and a fixing sleeve, characterized in that: the gas valve assembly has a gas outlet tip, the gas outlet tip is inserted into the vaporizer, an extension cylinder extends below the vaporizer, the fixing sleeve is fixedly sleeved on the outside of the extension cylinder and abuts against the outer wall of the extension cylinder, and the fixing sleeve is snapped and fixed to the housing.

[0005] By adopting the above technical solution, the extension cylinder below the gasifier is fixed by the fixing sleeve, which indirectly fixes the gasifier, thus making it less likely for the high-temperature gasifier to have a significant impact on the fixing sleeve, thereby ensuring fixation.

[0006] Optionally, a limiting plate is provided on the fixing sleeve, and the limiting plate is located between the piezoelectric component and the gasifier.

[0007] By adopting the above technical solution, and by using the limiting plate as a heat insulation and temperature baffle, the temperature of the gasifier is less likely to affect the pressing part of the piezoelectric component.

[0008] Optionally, the limiting plate is symmetrically provided with limiting blocks on both sides, and the top of the housing is symmetrically provided with locking grooves for the limiting blocks to slide and embed.

[0009] By adopting the above technical solution, the limiting block is slidably embedded into the locking groove, which facilitates the quick installation and fixing of the limiting plate and the fixing sleeve.

[0010] Optionally, a gradient slope is provided on the inner sidewall of the upper end of the fixing sleeve. The gradient slope is annular, and the inner diameter of the gradient slope gradually decreases from top to bottom.

[0011] By adopting the above technical solution, the extension tube is inserted into the fixed sleeve through a gradually tapered slope, thereby facilitating the fixed connection between the extension tube and the fixed sleeve.

[0012] Optionally, the gasifier has a flame outlet at the top, and a fire baffle is snapped onto the gasifier to cover the flame outlet. The fire baffle has a through-hole for the flame to pass through.

[0013] By adopting the above technical solution and installing fire shields, the spread of fire can be controlled to a certain extent, thereby improving the safety of product use.

[0014] Optionally, the inner wall of the fire shield has a plurality of fire-blocking protrusions extending inward, and the plurality of fire-blocking protrusions are evenly spaced circumferentially.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. The extension cylinder below the gasifier is fixed by the fixing sleeve, which indirectly fixes the gasifier, so that the high temperature of the gasifier is less likely to have a significant impact on the fixing sleeve, thus ensuring fixation; 2. By using the limiting plate as a heat insulation and baffle, the temperature of the gasifier is less likely to affect the pressing part of the piezoelectric component; 3. The extension tube is inserted into the fixed sleeve through a gradually tapered bevel, which facilitates the fixed connection between the extension tube and the fixed sleeve.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a lighter.

[0023] Reference Figures 1-4 The lighter includes a housing 1, a gas valve assembly 2 disposed within the housing 1, a piezoelectric component 3, a vaporizer 4, and a fixing sleeve 5. A fireproof cover 11 is snapped and fixed to the top of the housing 1, and a snap-fit ​​groove 12 is provided on the housing 1 for the fireproof cover 11 to be snapped in. The upper end of the gas valve assembly 2 is a gas outlet tip 21, which is inserted into the interior of the vaporizer 4. At the same time, the electric arc generated by the piezoelectric component 3 also occurs inside the vaporizer 4, thereby generating a flame through an electrochemical reaction inside the vaporizer 4, which overflows from the top of the vaporizer 4. The working principle of the gas valve assembly 2 and the piezoelectric component 3 is prior art and will not be described in detail in this embodiment.

[0024] An extension cylinder 41 is integrally extended below the gasifier 4, and the gas outlet tip 21 passes through the extension cylinder 41. A fixing sleeve 5 is provided on the outer side wall of the extension cylinder 41, and the inner side wall of the fixing sleeve 5 abuts against the extension cylinder 41. The fixing sleeve 5 is itself snapped and fixed to the housing 1.

[0025] Compared to the traditional method of directly fixing the gasifier 4 with a fixing sleeve 5, which is prone to deformation and damage due to the high temperature of the gasifier 4 over prolonged use, posing a safety hazard and requiring high material costs, the new method indirectly fixes the gasifier 4 by fitting the fixing sleeve 5 onto the extension cylinder 41. This avoids direct contact with the high-temperature gasifier 4, reducing the safety risk of heat damage to the fixing sleeve 5. Furthermore, since the extension cylinder 41 is located below the gasifier 4, the flame and temperature rise, resulting in a relatively lower temperature for the extension cylinder 41 and less impact on the fixing sleeve 5.

[0026] A limiting plate 51 extends from the fixed sleeve 5, located between the piezoelectric component 3 and the gasifier 4. The limiting plate 51 itself acts as a heat insulation plate and a fire baffle, preventing flames and temperatures from affecting the pressing part of the piezoelectric component 3. Two symmetrical and integrally formed limiting blocks 511 are provided on both sides of the limiting plate 51. The housing 1 has locking grooves 13 on both sides for the limiting blocks 511 to slide and engage, thereby securing the fixed sleeve 5 and the limiting plate 51 to the housing 1. A gradually tapering slope 52 is inclined on the inner wall of the upper end of the fixed sleeve 5. The gradually tapering slope 52 is annular, and its inner diameter gradually decreases from top to bottom. The gradually tapering slope 52 facilitates the insertion and engagement of the extension cylinder 41 into the fixed sleeve 5.

[0027] The gasifier 4 has a flame outlet 42 at its top, and a flame baffle 43 is snapped onto the flame outlet 42. The flame baffle 43 has a through-hole 44 for the flame to pass through. At the same time, a number of flame baffle protrusions 45 are integrally provided on the inner side wall of the flame baffle 43. In this embodiment, there are five flame baffle protrusions 45, which are evenly spaced around the perimeter.

[0028] By setting up the fire shield 43, the flames are less likely to spread randomly, and the fire can be better controlled.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
