Description

Technical Field

[0001] The utility model relates to the technical field of lighters, in particular to a lighter. Background Art

[0002] A lighter is generally defined as a small portable device used to produce a flame to ignite an object or light tobacco. Distilled naphtha in a lighter refers to a specific type of naphtha used as a lighter fuel. Distilled naphtha is usually a product obtained by distillation and fractionation during the petroleum processing process. It has a low boiling point and volatility and is suitable for use as a lighter fuel. This type of naphtha has high flammability and volatility, and can produce sufficient combustion effect in a lighter to ignite the fire or fuel.

[0003] For example, a liftable lighter disclosed in Chinese patent publication number (CN219530919U) records: "The advantages of the utility model are: when not igniting, the inner chamber can be completely hidden in the outer shell, making the lighter simple and elegant in appearance; when igniting, it is only necessary to operate the push block to slide the inner chamber out of the outer shell, and after the inner chamber slides out of the outer shell, the head cover and the elastic lock plate are automatically separated and opened, and the head cover is opened while driving the steel wheel to rotate for ignition operation, and the inner chamber automatically ignites when it slides out. When igniting multiple times in a row, it is only necessary to operate the head cover, which can avoid contact between fingers and the steel wheel, and is safe to use. Moreover, the inner chamber slides out or Slide into the outer shell, and the inner chamber slides while driving the head cover to automatically open or close, making the operation convenient and the structure novel". It also records: "With the increase in the market demand for lighters, more and more people require lighters to have better-looking appearance, more convenient and novel operation methods in addition to the fire-making function. As a result, there is a lighter that can be ignited after the body slides out of the outer shell and can be stored after the body slides into the outer shell. When it needs to be used, the head cover is opened first, and the force between the head cover and the outer shell is used to drive the body to slide out, and then the ignition operation is performed, which makes the operation cumbersome and there is a risk of the body being separated from the outer shell". Technical problems.

[0004] In summary, the device still has the following technical problems:

[0005] 1. The device ignites by moving the top cover upward to push the grinding wheel to rotate and generate sparks, and the sparks come into contact with the wick to complete the ignition. However, the long-term friction between the top cover and the grinding wheel will cause the top cover wall thickness to become thinner. Long-term use will lead to insufficient friction between the grinding wheel and the top cover, thus affecting the use of the lighter itself;

[0006] 2. The limiting component used for limiting the top cover in the above device is a spring. Since the spring is a plastic elastic material, repeated friction will cause the wall thickness of the spring to become thinner, and long-term use will affect the limiting function of the top cover.

[0007] 3. Since the fuel of this type of lighter is generally naphtha, the inner shell and the outer shell need to be disassembled to fill the naphtha, and the screw of the fuel filler port needs to be removed using professional tools such as screwdrivers. This refueling method is relatively cumbersome, which will affect the convenience of the lighter;

[0008] Therefore, it is necessary to propose a lighter to solve the technical problems mentioned in the above patents and provide a new technical solution. Utility Model Content

When the top cover limit block is closed, since the tooth groove on the surface of the grinding wheel is one-way, the grinding wheel does not rotate when the top cover limit block drives the grinding wheel fixing plate to reset, thereby reducing the wear of the friction flint and thereby increasing the service life of the flint.

Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0038] As described in the background technology:

[0039] 1. The device ignites by moving the top cover upward to push the grinding wheel to rotate and generate sparks, and the sparks come into contact with the wick to complete the ignition. However, the long-term friction between the top cover and the grinding wheel will cause the top cover wall thickness to become thinner. Long-term use will lead to insufficient friction between the grinding wheel and the top cover, thus affecting the use of the lighter itself;

[0040] 2. The limiting component used for limiting the top cover in the above device is a spring. Since the spring is a plastic elastic material, repeated friction will cause the wall thickness of the spring to become thinner, and long-term use will affect the limiting function of the top cover.

[0041] 3. Since the fuel of this type of lighter is generally naphtha, filling naphtha requires disassembling the inner shell and the outer shell, and using professional tools such as screwdrivers to remove the fuel filler screw. This refueling method is more cumbersome and will affect the convenience of the lighter.

[0042] In order to solve this technical problem, the utility model provides a lighter, which is applied to lighters.

When the lighter is turned on, the protrusion on the surface of the grinding wheel fixing plate 28 is clamped in the one-way clamping groove on the surface of the grinding wheel 26, and then the grinding wheel fixing plate 28 cooperates with the reset spring 30 to push the grinding wheel 26 to rotate, thereby completing rapid ignition. When the top cover limit clamping block 29 is closed, since the tooth groove on the surface of the grinding wheel 26 is one-way, the grinding wheel 26 does not rotate when the top cover limit clamping block 29 drives the grinding wheel fixing plate 28 to reset, thereby reducing the wear of the friction flint 32, and thereby increasing the service life of the flint.

[0052] Specifically, the ignition assembly includes a wick sealing ring 22, an ignition wick 23, a grinding wheel fixing shaft 24, a grinding wheel fixing sleeve 25, a grinding wheel 26, a top cover 27, a grinding wheel fixing plate 28, a top cover limit block 29, a reset spring 30 and a flint replacement unit. The top of the inner tank main shell 4 is fixedly connected with the wick sealing ring 22, the middle of the wick sealing ring 22 is fixedly connected with two ignition wicks 23, the top of the inner tank main shell 4 is fixedly connected with the grinding wheel fixing shaft 24, and the surface of the grinding wheel fixing shaft 24 is provided with a grinding wheel fixing sleeve 29. The wheel fixing sleeve 25 has a grinding wheel 26 fixedly connected to its surface, a top cover 27 rotatably connected to its surface, a grinding wheel fixing plate 28 fixedly connected to its bottom surface, and the grinding wheel fixing plate 28 rotatably connected to the surface of the grinding wheel fixing sleeve 25, a top cover 27 fixedly connected to its bottom surface, and a reset spring 30 is sleeved on its surface, and both ends of the reset spring 30 are respectively tightly attached to the bottom surface of the top cover 27 and the top surface of the inner tank main shell 4.

[0054] Specifically, a one-way tooth groove is provided on one side of the grinding wheel 26 close to the grinding wheel fixing plate 28, and an elastic protrusion is provided on one side of the grinding wheel fixing plate 28 close to the grinding wheel 26. The elastic protrusion provided on the surface of the grinding wheel 26 is clamped in the inside of the one-way tooth groove on the surface of the grinding wheel 26. A clamping block is provided on the top of the grinding wheel 26, and the grinding wheel 26 is clamped with the top cover limiting clamping block 29 through the protrusion on the top.

[0055] Through the above structural design,

[0056] When the lighter is in use, the pushing case 8 is pushed through the mounting groove 10 to drive the inner shell 4 to slide upward in the middle of the main shell 1. While the inner shell 4 moves upward, the buckle plate spring 18 pushes the top cover buckle plate 16 outward. When the bottom end of the buckle plate flipping protrusion 17 is higher than the top end of the side of the main shell 1, the buckle plate spring 18 pushes the top cover buckle plate 16 to flip outward and stop cooperating with the top cover limiting block 29 to limit the top cover 27. After the top cover 27 stops being limited, the reset spring 30 releases its elastic potential energy. When the reset spring 30 releases its elasticity, it can push the top cover 27 to flip on the surface of the grinding wheel fixing sleeve 25. The top cover 27 pushes the grinding wheel 26 to rotate through the grinding wheel fixing plate 28. When the grinding wheel 26 rotates, it rubs against the friction flint 32 at the bottom to generate sparks, and then the ignition wick 23 adsorbed with naphtha can be ignited. After use, the case 8 is pushed downward by sliding, and the inner tank main shell 4 is driven to shrink toward the inside of the main shell 1 while pushing the case 8 downward. When the top ends of both sides of the main shell 1 contact the buckle plate flipping protrusion 17 and the outer end of the top cover 27 respectively, the top cover 27 flips inward with the grinding wheel fixing sleeve 25 as the axis, and at the same time, the top cover buckle plate 16 flips inward with the reset shaft 15 as the axis. Then, the top cover limit block 29 can be snapped on through the top cover snap plate 16, and then the top cover 27 can be closed. After the top cover 27 has a thick wall, the fire extinguishing cover at the bottom covers the flame to form a low-oxygen space, so that the flame on the ignition wick 23 can be automatically extinguished. When the fuel inside the inner shell 4 is burned out, the case 8 will be pushed to rotate forty-five degrees, and the case 8 will be pushed to drive the button fixing piece 9 inside the inner shell 4 to rotate forty-five degrees so that the button fixing piece 9 itself is aligned with the inner circle of the through groove 5. While pushing the case 8 to rotate, the button direction fixing block 12 is squeezed to shrink the limit spring 11. After rotating forty-five degrees, the limit spring 11 is aligned with the groove on the back of the push case 8, and then can be snapped into the middle of the groove. After completion, the push case 8, the push button fixing part 7 and the button fixing plate 9 can be taken out from the middle of the main shell 1 and the inner shell 4. After adding the fuel into the inner shell 4, the push button fixing part 7 is inserted into the middle of the through groove 5 and the positioning slot 6, and the button fixing plate 9 is placed in the middle of the inner shell 4. After completion, the push case 8 is reversed forty-five degrees so that the four corners of the button fixing plate 9 can be snapped into the four sides of the inner wall of the inner shell 4, thereby completing the addition of fuel.
