DETAILED DESCRIPTION

[0020] Reference Figures 1 to 3 The figure shows a three-dimensional appearance diagram and a three-dimensional exploded diagram of a flame spray gun with a continuous flame spraying function according to the present invention. The flame spray gun 10 according to the present invention includes a body 20 and a control group 30; wherein:

[0021] Please continue to refer to Figures 4 to 7The figure shows a cross-sectional structure diagram and a usage state diagram of a flamethrower with a continuous flamethrowing function of the present invention. The control group 30 includes a start button 31 and a lock button 32. One end of the start button 31 is arranged in the body 20 and the other end protrudes outside the body 20. The two ends of the lock button 32 are arranged in the body 20. The opposite ends of the lock button 32 protrude outside the body 20 and are located on opposite sides of the body 20. The lock button 32 can move between a first locking position and an intermediate position or between the intermediate position and a second locking position. When the lock button 32 is in the intermediate position, the start button 31 can move between a standby position and a start position. When the start button 31 is in the start position and the lock button 32 is in the first locking position or the second locking position, the lock button 32 contacts and restricts the start button 31 in the start position.

[0022] The outer periphery of the start button 31 is provided with a latch flange 311, and the outer periphery of the locking button 32 is recessed with a connecting channel 321, a first latch groove 322 and a second latch groove 323. The first latch groove 322 and the second latch groove 323 are respectively connected to the same end of the connecting channel 321, and the first latch groove 322 and the second latch groove 323 are respectively arranged on opposite sides of the connecting channel 321. When the start button 31 moves between the standby position and the start position, the latch flange 311 can move in the connecting channel 321. When the start button 31 is in the start position and the locking button 32 is in the first locking position, the latch flange 311 is arranged in the first latch groove 322. When the start button 31 is in the start position and the locking button 32 is in the second locking position, the latch flange 311 is arranged in the second latch groove 323.

[0023] When the start button 31 is at the standby position, the latch flange 311 is disposed in the connecting channel 321 and restricts the locking button 32 to remain at the middle position.

[0024] The latch flange 311 is disposed on the outer circumference of the moving path of the start button 31 in the radial direction. The connecting channel 321 , the first latch groove 322 and the second latch groove 323 are disposed on the outer circumference of the moving path of the lock button 32 in the radial direction.

[0025] The locking button 32 is provided with a first pressing portion 324, a second pressing portion 325 and an outer protrusion 326. The first pressing portion 324 and the second pressing portion 325 are respectively provided at opposite ends of the locking button 32, and the outer protrusion 326 is provided between the first pressing portion 324 and the second pressing portion 325. The radial width of the first pressing portion 324 and the second pressing portion 325 along the moving path of the locking button 32 is smaller than the radial width of the outer protrusion 326 along the moving path of the locking button 32. The connecting channel 321, the first latch groove 322 and the second latch groove 323 are provided on the outer protrusion 326. The first latch groove 322 is provided on a side of the connecting channel 321 adjacent to the first pressing portion 324, and the second latch groove 323 is provided on a side of the connecting channel 321 adjacent to the second pressing portion 325.

[0026] The control group 30 is provided with a first elastic member 33 and a second elastic member 34. The first elastic member 33 is sleeved on the first pressing portion 324, one end of the first elastic member 33 abuts against the outer protrusion 326 and the other end abuts against the inner circumference of the main body 20, and the first elastic member 33 can push the locking button 32 to move toward the middle position. The second elastic member 34 is sleeved on the second pressing portion 325, one end of the second elastic member 34 abuts against the outer protrusion 326 and the other end abuts against the inner circumference of the main body 20, and the second elastic member 34 can push the locking button 32 to move toward the middle position.

[0027] The inner periphery of the first latch groove 322 is recessed with a first recessed edge 327, and the first recessed edge 327 is adjacent to the connecting channel 321. The inner periphery of the second latch groove 323 is recessed with a second recessed edge 328, and the second recessed edge 328 is adjacent to the connecting channel 321. When the start button 31 is in the start position and the locking button 32 is in the first locking position, the latch flange 311 abuts against the first recessed edge 327. When the start button 31 is in the start position and the locking button 32 is in the second locking position, the latch flange 311 abuts against the second recessed edge 328.

[0028] The flame spray gun 10 can provide a function of continuous flame spraying without pressing through the above structure. The flame spray gun 10 can spray flames after the start button 31 is pushed to the start position. When the flame spray gun 10 is started, the locking button 32 is pushed to the first locking position or the second locking position, so that the flame spray gun 10 stays in the started state without the user continuously pressing the start button 31. The first pressing portion 324 and the second pressing portion 325 are respectively arranged on both sides of the body 20, so that the flame spray gun 10 can be operated by left-handed and right-handed users.
