DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] The present application embodiment discloses a lighter grinding wheel. Figure 1 A lighter grinding wheel includes a wheel body 1, on which a plurality of grinding teeth 15 are machined and formed, and the plurality of grinding teeth 15 are arranged around the outer periphery of the wheel body 1 for detection, and the grinding teeth 15 are used for rubbing with a flint to ignite. The wheel body 1 is mounted on the lighter, and the wheel body 1 is rotatably connected to the lighter. A transmission wheel 2 is coaxially fixed on the wheel body 1, and the diameter of the transmission wheel 2 is larger than the diameter of the wheel body 1. The transmission wheel 2 partially extends out of the lighter, and the distribution direction of the transmission wheel 2 and the wheel body 1 is parallel to the rotation axis of the wheel body 1. The rotation of the transmission wheel 2 drives the wheel body 1 to rotate.

[0031] Reference Figure 1A plurality of elastic protrusions 21 are fixed on the outer peripheral wall of the transmission wheel 2. The plurality of elastic protrusions 21 are spaced around the outer peripheral wall of the transmission wheel 2. The elastic protrusions 21 are used to contact the user's hand. The elastic protrusions 21 are used to increase the friction between the transmission wheel 2 and the hand, making it easier for the user to rotate the grinding wheel.

[0032] Reference Figure 1 and Figure 2 , the transmission wheel 2 is slidably connected with a plurality of baffles 22, the sliding directions of the plurality of baffles 22 are perpendicular to the rotation axis 11 of the transmission wheel 2, and the plurality of baffles 22 are arranged around the outer periphery of the wheel body 1, and the baffles 22 slide into or extend out of the transmission wheel 2 in the direction close to the wheel body 1. The end of the transmission wheel 2 close to the wheel body 1 is spliced ​​with the outer peripheral wall of the wheel body 1 to form an annular opening 23, and the baffles 22 move to extend into or extend out of the annular opening 23. When the baffles 22 extend out of the transmission wheel 2, the distance between the end of the baffle 22 away from the transmission wheel 2 and the transmission wheel 2 is greater than the distance between the end of the wheel body 1 away from the transmission wheel 2 and the transmission wheel 2. The transmission wheel 2 is slidably connected with a driving member 3, and the position and number of the driving member 3 correspond to the position and number of the baffles 22 one by one, and the driving member 3 drives the corresponding baffles 22 to move.

[0033] Reference Figure 1 and Figure 2 The driving member 3 is a driving block 31, which is slidably connected to the transmission wheel 2. The sliding direction of the driving blocks 31 is perpendicular to the rotation axis 11 of the transmission wheel 2. The driving blocks 31 slide close to or away from the rotation axis 11 of the transmission wheel 2. The driving blocks 31 are located on the side of the corresponding baffle 22 away from the wheel body 1. The end of the driving block 31 close to the baffle 22 is processed to form a guide surface 311. The guide surface 311 is inclined from the direction close to the rotation axis of the transmission wheel 2 to the direction away from the corresponding baffle 22. The guide surface 311 is used to abut the corresponding baffle 22, so that the baffle 22 moves out of the transmission wheel 2 along the inclined direction of the guide surface 311. A plurality of elastic members 32 are fixed on the transmission wheel 2. The position and number of the elastic members 32 correspond to the position and number of the baffle 22. The opposite ends of the elastic members 32 are fixedly connected to the transmission wheel 2 and the corresponding driving blocks 31 respectively. The elastic members 32 tighten the corresponding baffle 22, so that the baffle 22 has a tendency to move and extend into the corresponding transmission wheel 2. A plurality of driving blocks 31 are all located below the elastic protrusion 21 . A positioning groove 221 is formed at one end of the elastic protrusion 21 close to the driving block 31 . The positioning groove 221 is used for the driving block 31 to be inserted and positioned.

[0034] When the user uses the lighter, the user's hand presses on the part of the transmission wheel 2 that protrudes from the lighter. When the user rotates the transmission wheel 2, the elastic protrusion 21 is squeezed and deformed downward, driving the driving block 31 to move toward the axis of the rotating shaft 11 of the transmission wheel 2. During this process, the guide surface 311 on the driving block 31 abuts against the corresponding baffle 22, so that the baffle 22 close to the user extends into the annular opening 23, thereby reducing the dust on the user's hand from falling into the wheel body 1.

[0035] Reference Figure 1 and Figure 2 The wheel body 1 includes a rotating shaft 11 and a friction wheel 12. The rotating shaft 11 is fixed on the lighter, and the friction wheel 12 is rotatably connected to the rotating shaft 11. The transmission wheel 2 is coaxially fixed with the friction wheel 12, and the transmission wheel 2 is rotatably connected to the rotating shaft 11. A sliding groove 121 is provided on the friction wheel 12, and the extending direction of the sliding groove 121 is perpendicular to the rotating shaft 11 of the friction wheel 12. A fastening member 13 is slidably connected to the friction wheel 12, and the fastening member 13 is a fastening block 131. The fastening block 131 is slidably connected in the sliding groove 121, and one end of the fastening member 13 close to the rotating shaft 11 is in contact with the rotating shaft 11. A positioning piece 14 is threadedly connected to the friction wheel 12, and the positioning piece 14 is a screw 141. The screw 141 is located on the side of the clamping block 131 away from the rotating shaft 11. The screw 141 is rotationally connected to the friction wheel 12. The rotating shaft 11 line between the screw 141 and the clamping block 131 is parallel to the sliding direction of the clamping block 131. The screw 141 drives the clamping block 131 to move and position by cooperating with the thread between the screw 141 and the friction wheel 12.

[0036] During use, the user can rotate the screw rod 141 according to his / her own habits to adjust the pressing force of the pressing member 13 on the rotating shaft 11, thereby adjusting the difficulty of the grinding wheel rotation.

[0037] Reference Figure 1 A paint layer 16 is sprayed on the surface of the friction wheel 12 , and the paint layer 16 covers the friction wheel 12 to protect the friction wheel 12 , thereby improving the wear resistance of the friction wheel 12 .

[0038] The implementation principle of a lighter grinding wheel in an embodiment of the present application is: when in use, the user rotates the transmission wheel 2 to drive the wheel body 1 to rotate the friction flint, which is beneficial to reduce the contact between the grinding wheel and the user, and is beneficial to reducing the contact between the wheel body 1 and the user, making the wheel body 1 less likely to wear, and is beneficial to increasing the service life of the wheel body 1.
