[0023] 2. By providing the adjusting block, the sliding of the outer tube is transmitted to the adjusting block by the transmission component, and the adjusting block is driven to rotate to adjust the communication state of the inner tube. When the outer tube is in the contracted state, the adjusting block blocks the inner tube to prevent the operator from accidentally touching the igniter and causing the inner tube to eject flames and cause danger; when the outer tube slides out, the transmission component is used to drive the adjusting block to rotate, so that the inner tube is communicated. After the outer tube is extended, the igniter can be used normally without manual adjustment, thus improving the convenience of using the igniter;

[0024] 3. Since heat-insulating materials are used, when the use is completed and the operator uses the turntable and the driving tube to drive the outer tube to retract, scalding will not occur; and even if the operator accidentally touches the gun head after the outer tube retracts, they will not be scalded, thus improving the safety and convenience of using the igniter.

[0037] The following further elaborates on this application in conjunction with the attached Figures 1-5 drawings.

[0038] The embodiment of this application discloses a lighter. Refer to Figure 1 and Figure 2 , the lighter includes a gun body 6 and a gun head. A flame outlet 61 is provided on the gun body 6, and an internal thread is provided on the gun body 6, and the internal thread is provided at the opening of the flame outlet 61.

[0039] Refer to Figure 3 and Figure 4 , the gun head includes an inner tube 1 and an outer tube 2. One end of the inner tube 1 is provided with an external thread, and the external thread on the inner tube 1 is adapted to the internal thread on the gun body 6. A handheld tube 12 is coaxially and fixedly provided on the inner tube 1.

[0040] During use, the operator holds the handheld tube 12 by hand and fixes the inner tube 1 and the gun body 6 using the thread.

[0041] Refer to Figure 4 and Figure 5 , the outer tube 2 is coaxially sleeved on the inner tube 1. Two first chutes 11 are opened on the outer side wall of the inner tube 1, the two first chutes 11 are arranged opposite to each other, and the length direction of the first chute 11 is the same as the length direction of the inner tube 1. Two slide blocks 21 are welded on the inner side wall of the outer tube 2, the slide blocks 21 correspond to the first chutes 11 one by one, the slide blocks 21 are slidably arranged in the first chutes 11, and the sliding axis is the same as the length direction of the first chute 11.

[0042] Refer to Figure 3 and Figure 4, a driving assembly 3 is arranged on the inner tube 1. The driving assembly 3 includes a turntable 32 and a driving tube 31. Both the turntable 32 and the driving tube 31 are made of rigid polyurethane with good heat insulation performance. The turntable 32 is sleeved on the inner tube 1 and is rotationally connected to the inner tube 1. The rotation axis is the same as the axis of the inner tube 1. The turntable 32 is located at one end of the driving tube 31 close to the gun body 6. The driving tube 31 is coaxially sleeved on the outer tube 2. The driving tube 31 is fixedly connected to the turntable 32. An internal thread is arranged on the inner side wall of the end of the driving tube 31 far from the turntable 32. An external thread is arranged on the outer side wall of the outer tube 2, and the external thread on the outer tube 2 meshes with the internal thread on the driving tube 31.

[0043] During use, the operator holds the hand-held tube 12 and the turntable 32 with both hands respectively, and then rotates the turntable 32. The turntable 32 drives the driving tube 31 to rotate, so as to drive the outer tube 2 to slide and expand relative to the inner tube 1.

[0044] Refer to Figure 4 and Figure 5 , an arc-shaped groove is formed on the inner side wall of the inner tube 1. The arc-shaped groove is located at one end of the inner tube 1 far from the turntable 32. An adjusting block 4 is arranged inside the inner tube 1. The adjusting block 4 is a spherical structure adapted to the arc-shaped groove. The adjusting block 4 is located in the arc-shaped groove and is rotationally connected to the inner tube 1 through a rotating shaft. The rotation axis is perpendicular to the axis of the inner tube 1. A communication hole 41 is formed on the adjusting block 4. The communication hole 41 penetrates through the adjusting block 4. The axis of the communication hole 41 is perpendicular to the rotation axis of the adjusting block 4.

[0045] Two second sliding grooves 22 are formed on the inner side wall of the outer tube 2. The two second sliding grooves 22 are arranged opposite to each other. The length direction of the second sliding grooves 22 is arranged along the length direction of the outer tube 2.

[0046] Refer to Figure 4 and Figure 5 , a transmission assembly 5 is arranged on the inner tube 1. There are two groups of the transmission assemblies 5, and they correspond to the second sliding grooves 22 one by one. The transmission assembly 5 includes a gear 51 and a rack 52. The gear 51 is located in the second sliding groove 22 and is fixedly connected to the adjusting block 4. The axis of the gear 51 is the same as the direction of the rotation axis of the adjusting block 4. The rack 52 is fixedly arranged in the second sliding groove 22 and is located at one end of the second sliding groove 22 close to the turntable 32. The gear 51 meshes with the rack 52.

[0047] When the outer tube 2 is in the contracted state, the axis of the communication hole 41 is perpendicular to the axis of the inner tube 1, and the adjusting block 4 isolates the inner tube 1. When the operator rotates the turntable 32 to drive the outer tube 2 to gradually extend and the gear 51 meshes with the rack 52, the outer tube 2 continues to extend, driving the rack 52 to move away from the turntable 32, thereby driving the gear 51 to rotate. The rotation of the gear 51 drives the adjusting block 4 to rotate. When the outer tube 2 extends to the maximum length, the adjusting block 4 rotates until the axis of the communication hole 41 is coaxial with the axis of the inner tube 1, and the inner tube 1 is in a communicating state.

[0048] The principle of implementation of the gun head of a lighter and the lighter according to an embodiment of the present application is as follows:

[0049] During use, the operator holds the hand-held tube 12 with the hand and fixes the inner tube 1 and the gun body 6 by means of threads. Then, the operator holds the hand-held tube 12 and the turntable 32 with both hands respectively, and then rotates the turntable 32. The turntable 32 drives the drive tube 31 to rotate, thereby driving the outer tube 2 to slide and extend relative to the inner tube 1, so that the gun head extends.

[0050] When the outer tube 2 is in the contracted state, the axis of the communication hole 41 is perpendicular to the axis of the inner tube 1, and the adjusting block 4 isolates the inner tube 1. When the operator rotates the turntable 32 to drive the outer tube 2 to gradually extend and the gear 51 meshes with the rack 52, the outer tube 2 continues to extend, driving the rack 52 to move away from the turntable 32, thereby driving the gear 51 to rotate. The rotation of the gear 51 drives the adjusting block 4 to rotate. When the outer tube 2 extends to the maximum length, the adjusting block 4 rotates until the axis of the communication hole 41 is coaxial with the axis of the inner tube 1, and the inner tube 1 is in a communicating state.

[0051] The above are all preferred embodiments of the present application. Without restricting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
