Description

Technical Field

[0001] This utility model relates to the field of lighter technology, and more specifically, to a blue flame direct-fire flint and steel lighter. Background Technology

[0002] Blue flame direct-shot lighters work by spraying a direct-shot nozzle that thoroughly mixes fuel and air. The fuel burns completely in sufficient oxygen, producing a high-temperature blue flame. This combustion method is more stable than the red flame of ordinary lighters, with concentrated and evenly distributed heat. Existing blue flame direct-shot flint and steel lighters ignite by pressing down on the flint wheel. Because the flint wheel is exposed at the top, it's difficult to avoid objects pressing down on it during manufacturing, causing continuous gas release and posing a safety hazard. Furthermore, the gasifier has poor insulation, allowing heat to be directly transferred to the metal casing during combustion. Even after the flame extinguishes, the metal casing remains hot, posing a risk of burns to the user. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides a blue flame direct-fire flint lighter, comprising a gas tank shell, a flint assembly, a handle, a pry bar, and a return spring. The gas tank shell contains a gas chamber, a first chamber, and a second chamber. The first chamber is equipped with a gas outlet, which communicates with the gas chamber. The second chamber is not communicated with the gas chamber. The flint assembly is installed in the second chamber. One end of the pry bar is located in the first chamber and connected to the gas outlet, while the other end is located in the second chamber. The handle slides vertically in the second chamber and is located at the top of the pry bar, contacting the pry bar. The return spring is located in the second chamber to drive the handle to return to its original position.

[0004] Optionally, the grinding wheel assembly includes a grinding wheel holder and a grinding wheel body, wherein the grinding wheel holder is snapped into the second chamber, and the grinding wheel body is rotatably mounted on the top of the grinding wheel holder.

[0005] Optionally, the portion of the skid located in the second chamber has a clearance opening, and the return spring is inserted into the clearance opening.

[0006] Optionally, the bottom of the handle is provided with a spring post, and the top of the reset spring is sleeved on the spring post.

[0007] Optionally, the blue flame direct-fire flint lighter also includes a gasification furnace and a ceramic ring, wherein the gasification furnace is plugged into the gas outlet and the ceramic ring is fitted onto the gas outlet of the gasification furnace.

[0008] Optionally, the ceramic ring has a connecting opening on the side facing the grinding wheel assembly, and the gas outlet of the gasifier is connected to the connecting opening.

[0009] Optionally, the gasifier is fixedly connected to the ceramic ring.

[0010] Optionally, an inner cover is provided at the opening of the first chamber, the ceramic ring is fixedly connected to the inner cover, and the ceramic ring is slidably connected to the gasifier.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows: 1. The gas release mechanism is located on the handle. By rotating the grinding wheel, pressing the handle, and pressing down the pry plate through the handle, gas can be released and the lighter can be ignited. Even if an object is pressing down on the grinding wheel, the lighter will not release gas, thus reducing safety hazards. 2. The return spring can be adjusted to increase the pressing weight as needed. Within the controlled operating force range, children cannot ignite the device, preventing accidental operation by children and thus improving safety during use. 3. When no downward pressure is applied to the handle, there is a certain distance between the bottom of the handle and the skid plate. Therefore, sufficient pressure must be applied to the handle to press it down a certain distance before the skid plate can be pressed down to release gas and ignite, thus reducing safety hazards during production or transportation.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix. Figure 1-6 This application will be described in further detail.

[0015] This utility model embodiment provides a blue flame direct-fire flint and steel lighter, see reference. Figure 1 The blue flame direct-fire flint lighter includes a gas tank shell 1, a flint assembly 2, a handle 3, a pry bar 4, and a return spring 5. The gas tank shell 1 contains a gas chamber (not shown in the figure), a first chamber 11, and a second chamber 12. The first chamber 11 and the second chamber 12 are located on top of the gas chamber and are arranged adjacent to each other in the left-right direction. The first chamber 11 is equipped with a gas outlet 13 (existing technology, capable of releasing or closing gas through telescopic movement; the specific structure is not described in detail). The gas outlet 13 communicates with the gas chamber, while the second chamber 12 is not connected to the gas chamber. The flint assembly 2 is installed in the second chamber 12 to generate a spark. One end of the pry bar 4 is located in the first chamber 11 and connected to the air outlet 13 (existing connection method), and the other end is located in the second chamber 12. The handle 3 slides vertically in the second chamber 12, and the handle 3 is located at the top of the pry bar 4 and in contact with the pry bar 4. The reset spring 5 is located in the second chamber 12 to drive the handle 3 to reset.

[0016] The return spring 5 can be adjusted to increase the pressing weight as needed, preventing children from igniting the device within a controlled operating force range, thus improving safety during use. Both the first chamber 11 and the second chamber 12 have open tops.

[0017] Reference Figure 1 and Figure 2 The grinding wheel assembly 2 includes a grinding wheel frame 21, a grinding wheel body 22, and a flint. The flint is fixedly mounted on the top of the grinding wheel frame 21. Two integrally formed support plates are spaced apart on the top of the grinding wheel frame 21. Each support plate has a through-hole on its side wall. The grinding wheel body 22 is located between the two support plates, and a rotating shaft is fixedly mounted on the grinding wheel body 22. The two ends of the rotating shaft are rotatably inserted into the two rotating holes, thus rotatably connecting the grinding wheel body 22 to the grinding wheel frame 21. The flint is located between the two support plates and at the bottom of the grinding wheel body 22, in contact with it. Therefore, rotating the grinding wheel body 22 will cause friction between the grinding wheel body 22 and the flint, generating sparks. The grinding wheel frame 21, the grinding wheel body 22, and the flint form a single module, improving the convenience of production assembly.

[0018] The grinding wheel holder 21 has snap-fit ​​protrusions integrally formed on both the front and rear opposite sides. The corresponding cavity wall of the second chamber 12 is provided with snap-fit ​​grooves. The snap-fit ​​protrusions are snapped into the snap-fit ​​grooves, so that the grinding wheel holder 21 is snapped and fixedly installed in the second chamber 12, which makes it more convenient to assemble during production.

[0019] Reference Figures 1 to 4Both the handle 3 and the return spring 5 are located on the side of the grinding wheel frame 21 away from the first chamber 11. The return spring 5 is located at the bottom of the handle 3, and a spring post 31 is integrally formed at the bottom of the handle 3. The top of the return spring 5 is sleeved on the spring post 31 and abuts against the handle 3. The bottom of the return spring 5 abuts against the cavity wall of the second chamber 12 at the end away from the top opening. Thus, when no downward pressure is applied to the handle 3, the return spring 5 will drive the handle 3 to rise and return to its original position. The top opening of the second chamber 12 is provided with a blocking flange, and the outer wall of the handle 3 is provided with a mating flange. The blocking flange is located directly above the mating flange. When no downward pressure is applied to the handle 3, under the action of the return spring 5, the top of the mating flange abuts against the bottom of the blocking flange, thereby limiting the handle 3 and making it difficult for the handle 3 to detach from the second chamber 12. The handle 3 has a cavity in the middle, so during installation, the handle 3 can be driven to undergo a slight elastic deformation so that it can be inserted into the second chamber 12 through the blocking flange.

[0020] A connecting notch is provided between the first chamber 11 and the second chamber 12, through which the skid 4 passes. A clearance opening is provided on the portion of the skid 4 located in the second chamber 12, through which the return spring 5 passes. The bottom of the handle 3 is spaced apart from the skid 4. When no downward pressure is applied to the handle 3, there is a certain distance between the bottom of the handle 3 and the skid 4. Therefore, sufficient pressure must be applied to the handle 3 to press it down a certain distance before the skid 4 can be pressed down for gas release and ignition, reducing safety hazards during production or transportation. When the pressure applied to the handle 3 is released, the return spring 5 drives the handle 3 to move upwards and reset. The skid 4, under the elastic force of the nozzle itself (in the existing structure), moves and resets, thus closing and preventing gas release.

[0021] Reference Figures 1 to 5 The blue flame direct-fire flint and steel lighter also includes a gasifier 14 and a ceramic ring 15. An inner cover 16 is installed at the opening at the top of the first chamber 11. A metal windproof cover is fitted over the inner cover 16, and the windproof cover is fixedly connected to the gas chamber shell 1. Both the gasifier 14 and the ceramic ring 15 are located inside the windproof cover, with the ceramic ring 15 inserted into the inner cover 16. The gasifier 14 is connected to the gas outlet 13 and moves synchronously. Rotating the flint and steel wheel and pressing down the lever 4 causes the nozzle to spray liquid fuel from the gas chamber into the gasifier 14. The gasifier 14 then converts the liquid fuel into gaseous fuel, and the sparks generated by the flint and steel wheel ignite the gaseous fuel to form a flame. The ceramic ring 15 is set at the gas outlet of the gasifier 14. On the one hand, it prevents the gaseous fuel from dispersing too much after it is discharged from the gas outlet of the gasifier 14. On the other hand, it also has a heat insulation effect, so that the wind shield will not get too hot and reduce the safety hazard of burns to users.

[0022] The ceramic ring 15 has a connecting opening 151 on the side facing the flint, and the inner cover 16 has a notch on the side facing the flint that communicates with the connecting opening 151. The gas outlet of the gasifier 14 is connected to the connecting opening 151 and the notch. In this way, the sparks generated by the grinding wheel body 22 and the flint can ignite the gaseous fuel through the connecting opening 151, which helps to ignite the gaseous fuel in a timely manner.

[0023] Reference Figures 1 to 6 The gasifier 14 and the ceramic ring 15 can be fixedly connected or separately connected. If the gasifier 14 and the ceramic ring 15 are fixedly connected, the ceramic ring 15 is interference-fitted onto the gasifier 14, and the ceramic ring 15 is slidably inserted into the inner cover 16. When the gasifier 14 and the nozzle move up and down, the ceramic ring 15 will also move synchronously. If the gasifier 14 and the ceramic ring 15 are separately connected, the ceramic ring 15 is fixedly connected to the inner cover 16, that is, the gasifier 14 will be inserted inside the ceramic ring 15 and move up and down relative to the ceramic ring 15. In this embodiment, the gasifier 14 and the ceramic ring 15 are preferably fixedly connected.

[0024] The implementation principle of the blue flame direct-fire flint lighter in this application embodiment is as follows: the gas release mechanism is set on the handle 3. When igniting, the flint wheel is rotated, the handle 3 is pressed down, and the pry plate 4 is pressed down by the handle 3 to release gas for ignition. Even if an object is pressing down on the flint wheel, the lighter will not release gas, reducing safety hazards. The return spring 5 can increase the pressing weight as needed. Within the controlled operating force range, children cannot ignite the lighter, improving safety during use. The ceramic ring 15 is sleeved at the gas outlet of the gasifier 14. On the one hand, it prevents the gaseous fuel from being too dispersed after being discharged from the gas outlet of the gasifier 14. On the other hand, it also has a heat insulation effect, preventing the wind shield from becoming too hot and reducing the safety hazard of burns to the user.
