Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Embodiment 1:
[0022] See also Figures 1 to 4 A flip-top grinding wheel lighter comprises a shell 1, a protective cover 3 is rotatably connected to the top of the shell 1, a grinding wheel lighter body 2 is arranged inside the shell 1, a first limit block 8 is fixedly installed on the inner wall of the protective cover 3, a support plate 9 is fixedly installed inside the shell 1, a square rod 10 is rotatably connected to the top of the support plate 9, one end of the square rod 10 is fixedly connected to the second limit block 11, a slide groove 12 is provided inside the square rod 10, a slider 14 is slidably connected inside the slide groove 12, a rack 15 is slidably connected inside the shell 1, one end of the rack 15 is rotatably connected to the slider 14, one end of the rack 15 is fixedly connected to a button 4, a telescopic spring 13 is fixedly connected inside the shell 1, one end of the telescopic spring 13 is fixedly connected to the button 4, the rack 15 is controlled to move by pressing the button 4, so that the slider 14 slides inside the slide groove 12, driving the square rod 10 to rotate, so that the second limit block 11 moves away from The first limit block 8 can release the limit on the protective cover 3. At this time, the grinding wheel lighter body 2 can be used by opening the protective cover 3. After use, the protective cover 3 can be rotated so that the protective cover 3 covers the top of the shell body 1. The square rod 10 is reset by the elastic force of the telescopic spring 13, so that the second limit block 11 limits the first limit block 8, which improves the firmness between the shell body 1 and the protective cover 3, so that the shell body 1 and the protective cover 3 will not be easily separated, preventing safety hazards. One side of the first limit block 8 and the second limit block 11 are both provided with an inclined surface. When the protective cover 3 is closed, the first limit block 8 squeezes the second limit block 11, and the square rod 10 automatically moves to one side. When the protective cover 3 is completely covered on the top of the shell body 1, the square rod 10 is under the elastic force of the telescopic spring 13, so that the second limit block 11 blocks the first limit block 8, thereby limiting the protective cover 3.
[0023] Embodiment 2:
[0024] The housing 1 is internally rotatably connected with a first rotating shaft 16, and the upper end of the first rotating shaft 16 is connected with a first gear 17 through a one-way bearing, that is, when the button 4 is pressed, the rack 15 is meshed with the first gear 17, and when the button 4 is reset by the elastic force of the telescopic spring 13, the rack 15 cannot control the rotation of the first gear 17, and the first gear 17 is meshed with the rack 15. The lower end of the first rotating shaft 16 is fixedly connected with a second bevel gear 18, and the housing 1 is internally rotatably connected with a second rotating shaft 19, one end of the second rotating shaft 19 is fixedly connected with a third bevel gear 20, and the second bevel gear 18 is meshed with the third bevel gear 20, and the other end of the second rotating shaft 19 is fixedly connected with a pointer 6, and a circular groove 5 is provided on one side of the housing 1, and a circular scale line 7 is arranged inside the circular groove 5. , the number corresponding to the circular scale line 7 can be marked with a number, so as to refer to the number corresponding to the initial position and the number corresponding to the final position to understand the number of times the lighter is used. When the button 4 is pressed, the rack 15 meshes with the first gear 17, so that the first rotating shaft 16 rotates, and then the pointer 6 at one end of the second rotating shaft 19 rotates under the meshing connection of the second bevel gear 18 and the third bevel gear 20, that is, when the protective cover 3 completes the opening and closing action, the pointer 6 rotates at a fixed angle. By recording the initial position of the pointer 6 and then understanding the rotation range of the pointer 6 according to the circular scale line 7, the number of times the lighter is used on that day can be understood according to the circular scale line 7, and the number of times the smoker smokes can be recorded, thereby improving the functionality of the device.
