Description

Technical Field

[0001] The invention relates to the technical field of lighters, in particular to a lighter with a long service life and a self-locking function. Background Art

[0002] A lighter is a small fire-making device. It is mainly used for making fire, smoking, cooking and other fire-making. The main parts of a lighter are the ignition mechanism and the gas storage box. When the ignition mechanism is activated, sparks burst out and shoot towards the gas area to ignite the gas.

[0003] Traditional lighters will immediately catch fire when the switch is pressed. The safety factor is low and it is easy to cause danger due to accidental triggering. A solution is proposed below to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a lighter with a long service life and a self-locking function, thereby avoiding the danger of triggering due to accidental touch and improving safety.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A lighter with a long service life and a self-locking function comprises a shell, the upper end surface of the shell is fixedly connected to a bracket, an air outlet valve is arranged on the bracket, the air outlet valve passes through the bracket and is connected with the shell, the bracket is penetrated by a flamethrower, the flamethrower is connected with the air valve through a rubber hose, a flint assembly is arranged on one side of the flamethrower, an ignition assembly is rotatably arranged inside the shell, the output end of the ignition assembly and the output end of the flint assembly are in contact with each other, a spring piece is arranged on the bracket, one end of the spring piece is fixedly connected to a folding plate, a notch is provided on the folding plate, the notch is clamped on the control end of the air outlet valve, the end of the spring piece away from the folding plate is fixedly connected to a top plate, and the top plate is located on the top of the ignition assembly.

[0007] When the above technical solution is adopted, the user first pushes the ignition assembly upwards. When the ignition assembly moves upwards, it will drive one end of the top plate to move upwards. The upward movement of the top plate will drive one end of the shrapnel to move upwards. One end of the shrapnel will drive one end of the folding plate to move upwards. The notch on the folding plate will move upwards, so that the notch will push the air outlet valve to open. The interior of the shell is used to store gas. At this time, the gas inside the shell will enter the flamethrower through the air outlet valve and the guidance of the rubber hose. At this time, the ignition device is rotated, and the ignition device rotates and rubs against the flint assembly to form sparks. Since the flint assembly and the ignition assembly are both located on one side of the flamethrower, the sparks will ignite the gas, thereby forming a flame. The ignition assembly cooperates with the flint assembly to form a spark to ignite the gas. At the same time, the ignition assembly and the shrapnel cooperate to have a self-locking effect on the opening and closing of the air outlet valve to ensure safety.

[0008] Preferably, the ignition assembly includes a central shaft, an inner sleeve, an outer sleeve, and a flint. One end of the central shaft is rotatably arranged on the shell, and one end of the central shaft is rotatably matched with the bracket. The outer sleeve is sleeved on the central shaft, and the outer sleeve and the central shaft are slidably matched. The inner sleeve is located between the outer sleeve and the central shaft, and the inner sleeve and the central shaft are slidably matched. The outer sleeve and the inner sleeve are threadedly matched. The flint is located on one side of the flamethrower, and the flint is sleeved on the central shaft. A limiting device that cooperates with the outer cylinder is provided inside the central shaft.

[0009] By adopting the above technical solution, the outer sleeve is first pushed upward, and the outer sleeve will drive the inner sleeve, which will slide upward along the center axis, so that the inner sleeve will push the top plate, and the limit device and the inner sleeve will stabilize the two ends of the outer sleeve. When the outer sleeve moves to the top, the limit device will fix it to prevent the outer sleeve from resetting. The outer sleeve is rotated, and the threads of the outer sleeve and the inner sleeve are matched. When the threads of the outer sleeve and the inner sleeve are rotated to the top, they will no longer move, so that the rotating outer sleeve will drive the inner sleeve to rotate together, and the inner sleeve will drive the center axis to rotate together. The rotation of the center axis will drive the flint to rotate, so that sparks are generated by the friction between the rotating flint and the flint assembly.

[0010] Preferably, the limiting device includes a spring and a locking ball. A through groove is provided on the outer arc surface of the central axis. The spring is located inside the through groove. Two locking balls are provided. The two locking balls are respectively slidably arranged at the two ends of the through groove. The two locking balls are respectively in contact with the two ends of the spring. Two arc grooves are provided on the upper and lower inside of the outer sleeve. The cross-section of the arc groove is triangular.

[0011] By adopting the above technical solution, when the outer coat moves, the outer coat will drive the arc groove on the outer coat to move. Since the cross-section of the arc groove is triangular, when the arc groove moves, the side of the arc groove will squeeze the card ball, and the card ball will squeeze spring 1, thereby retracting it into the through groove, that is, the card ball moves out from the inside of the arc groove, and when the next arc groove corresponds to the through groove, spring 1 will push the card ball out and snap it into the inside of the card ball. The cooperation of the card ball and the arc groove allows the user to have a sense of segmentation when pushing the outer coat, and the cooperation of the card ball and the arc groove supports the outer coat to prevent the outer coat from resetting under the action of gravity. At the same time, the design of double card balls can balance the force on the outer coat to avoid wear caused by unilateral force. At the same time, the card ball and the outer cylinder are both made of metal, which improves wear resistance and extends service life.

[0012] Preferably, the flint assembly includes an adjusting block, a second spring and a second flint. A placement groove is provided inside the shell, and the second flint is slidably arranged inside the placement groove. One end of the second flint extends from the placement groove and contacts the output end of the ignition assembly. The second spring is located inside the adjusting groove, and the second spring is located on one side of the second flint. The adjusting block is located at the end of the spring away from the second flint, and the adjusting block and the placement groove are threadedly matched.

[0013] By adopting the above technical scheme, the placement groove plays a role in placing the flint 2, and sparks are generated by the friction between the flint 2 and the flint 1. At the same time, the adjusting block plays a fixing role on the flint 2, and the spring 2 plays a buffering role on the flint 2 to prevent the flint 2 from breaking due to excessive force of the adjusting block. At the same time, the spring 2 plays a compensating role. When the volume of flint 1 and flint 2 decreases due to friction, the spring 2 pushes the flint 2, thereby ensuring that the flint 2 and flint 1 always remain in close contact.

[0014] Preferably, a protective shell is provided on the outside of the bracket, the protective shell is snap-connected with the housing, and a flamethrower tube is inserted into the protective shell, and the flamethrower tube corresponds to the flamethrower port.

[0015] By adopting the above technical solution, the protective shell plays a protective role to prevent the external environment from damaging the internal components of the protective shell. At the same time, the flamethrower tube and the flamethrower port correspond to each other, which facilitates the ejection of flames.

[0016] Preferably, a plurality of anti-slip grooves are evenly arranged on the surface of the outer cover.

[0017] By adopting the above technical solution, the anti-skid grooves increase the friction force, and the anti-skid grooves arranged in a cross shape facilitate the user to rotate and push the jacket.

[0018] Preferably, the side area of ​​the protective shell is symmetrical and is fixedly connected with a connecting piece, a connecting rod is passed through the connecting piece, and the connecting rod passes through the shell.

[0019] By adopting the above technical solution, the user can easily take out the protective shell through the snap-on design of the connecting rod and the connecting piece.

[0020] Preferably, the outer casing of the housing is provided with a metal protective box.

[0021] By adopting the above technical solution, the metal protection box protects the plastic shell and ensures safety.

[0022] Beneficial effects: The gas valve is first opened through the ignition component, and then sparks are generated through the cooperation of the ignition component and the flint component to ignite the gas, avoiding igniting the gas in one step to ensure safety. At the same time, the limit component will limit the jacket to prevent it from falling under the action of gravity of the jacket. At the same time, it is made of metal material and smoothed to reduce friction. Symmetrical force is used to avoid wear caused by one-sided force and ensure service life.

[0031] See Figures 1 to 6As shown, a lighter with a long service life and a self-locking function comprises a shell 1, the outer sleeve of the shell 1 is provided with a metal protection box 30, the metal protection box 30 protects the plastic shell 1 and ensures safety, the upper end surface of the shell 1 is fixedly connected with a bracket 2, the bracket 2 is provided with an air outlet valve 3, the air outlet valve 3 passes through the bracket 2 and is connected with the shell 1, the bracket 2 is penetrated with a flamethrower 4, the flamethrower 4 is connected with the air valve through a rubber hose 5, the outer sleeve of the bracket 2 is provided with a protective shell 25, the protective shell 25 plays a protective role to prevent the external environment from damaging the internal components of the protective shell 25, the side area of ​​the protective shell 25 is symmetrical and fixedly connected with a connecting piece 28, the connecting piece 28 is penetrated with a connecting rod 29, the connecting rod 29 passes through the shell 1, and the snap-fit ​​design of the connecting rod 29 and the connecting piece 28 facilitates the user to take out the protective shell 25, and a flamethrower tube 26 is inserted into the protective shell 25, the flamethrower tube 26 corresponds to the flamethrower 4, and the flamethrower tube 26 corresponds to the flamethrower 4, so as to facilitate the ejection of flames.

[0032] An ignition assembly 7 is rotatably arranged inside the shell 1, and the ignition assembly 7 includes a central axis 12, an inner sleeve 13, an outer sleeve 14, and a flint 15. One end of the central axis 12 is rotatably arranged on the shell 1, and one end of the central axis 12 is rotatably matched with the bracket 2. The outer sleeve 14 is sleeved on the central axis 12, and the outer sleeve 14 and the central axis 12 are slidably matched. A plurality of anti-skid grooves 27 are evenly provided on the surface of the outer sleeve 14, and the anti-skid grooves 27 increase the friction force, and the anti-skid grooves 27 arranged in a cross shape are convenient for the user to rotate and push the outer sleeve 14. The inner sleeve 13 is located between the outer sleeve 14 and the central axis 12, and the inner sleeve 13 and the central axis 12 are slidably matched. The outer sleeve 14 and the inner sleeve 13 are threadedly matched. The flint 15 is located on one side of the flamethrower 4, and the flint is sleeved on the central axis 12. A limiting device 16 matching the outer cylinder is provided inside the central axis 12.

[0033] The limiting device 16 includes a spring 17 and a locking ball 18. A through groove 19 is provided on the outer arc surface of the central axis 12. The spring is located inside the through groove 19. Two locking balls 18 are provided. The two locking balls 18 are respectively slidably arranged at the two ends of the through groove 19. The two locking balls 18 are respectively in contact with the two ends of the spring. Two arc grooves 20 are provided in the upper and lower parts of the inner part of the outer sleeve 14. The cross-section of the arc groove 20 is triangular.

[0034] When in use, first push the outer sleeve 14 upward, the outer sleeve 14 will drive the inner sleeve 13, the inner sleeve 13 slides upward along the central axis 12, and the limit device 16 and the inner sleeve 13 have a stabilizing effect on the two ends of the outer sleeve 14. When the outer sleeve 14 moves, the outer sleeve 14 will drive the arc groove 20 on the outer sleeve 14 to move.

[0035] A spring sheet 8 is arranged on the bracket 2, one end of which is fixedly connected to a folding plate 9, a notch 10 is provided on the folding plate 9, the notch 10 is clamped on the control end of the outlet valve 3, and one end of the spring sheet 8 away from the folding plate 9 is fixedly connected to a top plate 11, which is located at the top of the inner tube.

[0036] The inner sleeve 13 will push one end of the top plate 11 to move upward, and the upward movement of the top plate 11 will drive one end of the spring sheet 8 to move upward, and one end of the spring sheet 8 will drive one end of the folding plate 9 to move upward, and the notch 10 on the folding plate 9 will move upward, so that the notch 10 will push the outlet valve 3 to open, and the inside of the shell 1 is used to store gas. At this time, the gas inside the shell 1 will pass through the outlet valve 3 and enter the flame-spraying port 4 under the guidance of the rubber hose 5. When the outer sleeve 14 moves to the top, the limit device 16 plays a fixing effect to prevent the outer sleeve 14 from resetting.

[0037] Thereby, the outer sleeve 14 is rotated, and the threads of the outer sleeve 14 and the inner sleeve 13 are matched. When the threads of the outer sleeve 14 and the inner sleeve 13 are screwed to the top, they will not move anymore, so that the rotating outer sleeve 14 will drive the inner sleeve 13 to rotate together, and the inner sleeve 13 will drive the central shaft 12 to rotate together, and the rotation of the central shaft 12 will drive the flint to rotate.

[0038] A flint assembly 6 is provided on one side of the flamethrower 4, and the output end of the ignition assembly 7 and the output end of the flint assembly 6 are in contact with each other. The flint assembly 6 includes an adjusting block 21, a spring 22 and a flint 23. A placement groove 24 is opened inside the shell 1, and the flint 23 is slidably arranged inside the placement groove 24. One end of the flint 23 extends from the inside of the placement groove 24 and contacts with the output end of the ignition assembly 7. The spring 22 is located inside the adjusting groove, and the spring 22 is located on one side of the flint 23. The adjusting block 21 is located at the end of the spring away from the flint 23, and the adjusting block 21 and the placement groove 24 are threadedly matched.

[0039] The placement groove 24 is used to place the flint 23, and sparks are generated by the friction between the flint 23 and the flint 1. At the same time, the adjusting block 21 fixes the flint 23, and the spring 22 buffers the flint 23 to prevent the flint 23 from breaking due to excessive force of the adjusting block 21. At the same time, the spring 22 compensates. When the volume of flint 1 and flint 23 decreases due to friction, the spring 22 pushes the flint 23, thereby ensuring that the flint 23 and flint 1 always remain in close contact. The friction between the flint 1 and flint 23 will generate sparks. Since the flint assembly 6 and the ignition assembly 7 are both located on one side of the flamethrower 4, the sparks will ignite the gas, thereby forming a flame.

[0040] The ignition assembly 7 cooperates with the flint assembly 6 to form a spark to ignite the gas. At the same time, the ignition assembly 7 and the shrapnel 8 cooperate to achieve a self-locking effect on the opening and closing of the outlet valve 3, thereby ensuring safety.
