[0048] The technical solutions of the present application will be described in detail below in conjunction with specific embodiments.

[0049] At present, after the ignition gun is ignited, the barrel or the wind cover is heated for a long time to form high temperature, and manual lifting of the barrel has the risk of scalding, and the ignition gun is large in size, occupies more space, and is inconvenient to carry.

[0050] Please participate Figure 1 In view of the above problems, the present application provides an ignition gun 100, which comprises a rotating sleeve 4, an extension device, an ignition device and a sleeve 1. The ignition device comprises a barrel 21, and the barrel 21 is movably arranged in the sleeve 1. Please refer to Figure 7The telescopic device is arranged on the sleeve 1, and comprises a limiting component 31 and a pushing component 32 connected with each other. The pushing component 32 is connected with the barrel 21, and is provided with a first boss 3221. The limiting component 31 is connected with the sleeve 1, and is used for limiting rotation of the pushing component 32. Please refer to Figure 2 and Figure 4 The rotating sleeve 4 is arranged on the sleeve 1, and is provided with a threaded structure 41 matched with the first boss 3221. The rotating sleeve 4 is used for rotating relative to the sleeve 1 to the unlocking position D and the locking position L, so as to respectively make the pushing component 32 move upward and downward along the height direction of the sleeve 1 through the first boss 3221, and drive the barrel 21 to move upward and downward relative to the sleeve 1. Please refer to Figure 2 (b), by rotating the rotating sleeve 4, when the rotating sleeve 4 rotates to the locking position L, the first boss 3221 moves downward along the threaded structure 41, so as to make the pushing component 32 move downward, and further drive the barrel 21 to move downward, and the barrel 21 is retracted relative to the sleeve 1. Please refer to Figure 4 (b), when the rotating sleeve 4 rotates to the unlocking position D, the first boss 3221 moves upward along the threaded structure 41, so as to make the pushing component 32 move upward, and further drive the barrel 21 to move upward, and the barrel 21 is extended relative to the sleeve 1. Therefore, the ignition gun 100 of the present application does not need to lift the barrel 21, and reduces the risk of scalding. At the same time, the retracted barrel 21 can reduce the volume of the ignition gun 100, and is convenient to carry.

[0051] Exemplarily, the threaded structure 41 can be arranged on the inner wall or the outer wall of the rotating sleeve 4. When the threaded structure 41 is arranged on the inner wall of the rotating sleeve 4, the pushing component 32 is provided with the first boss 3221 towards the inner wall of the rotating sleeve 4. When the threaded structure 41 is arranged on the outer wall of the rotating sleeve 4, the pushing component 32 is provided with the first boss 3221 towards the outer wall of the rotating sleeve 4.

[0052] Further exemplarily, the threaded structure 41 can be a threaded boss, a threaded groove or a threaded through slot, which can be matched with the first boss 3221. When the surface of the rotating sleeve 4 is provided with a boss to form a threaded boss, the first boss 3221 abuts on the threaded boss to move upward. When the surface of the rotating sleeve 4 is concave to form a threaded groove, the first boss 3221 extends into the threaded groove to move upward along the threaded groove. When the barrel wall of the rotating sleeve 4 is slotted to form a threaded through slot, the first boss 3221 is arranged in the threaded through slot to move upward along the threaded through slot.

[0053] Please refer to Figure 9 and Figure 10 In some embodiments, the inner wall of the rotating sleeve 4 is provided with a threaded boss. The limiting component 31 comprises a limiting portion 311 and a first support strip 312 connected to the bottom of the limiting portion 311. The peripheral wall of the limiting portion 311 is surrounded to form a containing space 313. Please refer toFigure 11 and Figure 12 The pushing component 32 comprises an abutting portion 321 and a second support strip 322 connected to the bottom of the abutting portion 321. Please refer to Figure 8 The abutting portion 321 of the pushing component 32 is arranged in the accommodating space 313 and connected to the limiting portion 311. The second support strip 322 is movably arranged in the rotating sleeve 4. The second support strip 322 is provided with a first boss 3221 facing the inner wall of the rotating sleeve 4. The second support strip 322 moves up and down along the height direction of the casing 1 through the first boss 3221. It can be understood that the pushing component 32 is arranged in the accommodating space 313 surrounded by the peripheral wall of the limiting component 31, and the limiting component 31 is arranged in the rotating sleeve 4, which can improve the space utilization of the rotating sleeve 4 and realize compact structure. In addition, compared with arranging a support plate or a support cylinder below the limiting portion and the abutting portion 321, arranging the first support strip 312 and the second support strip 322 can further save the space inside the rotating sleeve 4 and provide more space for placing other components.

[0054] Please refer to Figure 7 and Figure 8 In some embodiments, the peripheral wall of the limiting portion 311 is provided with a first ridge 3113 facing the second support strip 322. The second support strip 322 is bent towards the first ridge 3113 to form a second boss 3222. When the rotating sleeve 4 rotates to the unlocking position D, the second support strip 322 rises to make the second boss 3222 abut against the first ridge 3113. After the second boss 3222 abuts against the first ridge 3113, the excessive rising of the second support strip 322 can be limited.

[0055] Please refer to Figure 7 and Figure 8 In some embodiments, the first support strip 312 is provided with a second ridge 3121 facing the second support strip 322. When the rotating sleeve 4 rotates to the locking position L, the second support strip 322 descends to abut against the second ridge 3121. After the second support strip 322 abuts against the second ridge 3121, the excessive descending of the second support strip 322 can be limited.

[0056] Please refer to Figure 7In some embodiments, the telescopic device further comprises a fixing member 33 connected to the sleeve 1 and the limiting member 31, and the fixing member 33 and the limiting member 31 jointly form a guide groove for the lifting movement of the second support bar 322. When the first boss 3221 of the pushing member 32 cooperates with the threaded structure 41 of the rotating sleeve 4, the threaded structure 41 drives the first boss 3221 to rotate, and the guide groove prevents the first boss 3221 from rotating and only moves up and down. For example, the guide groove can be formed on the fixing member 33, and the limiting member 31 is connected to the fixing member 33 to cover the guide groove, or the guide groove can be formed on the limiting member 31, and the fixing member 33 is connected to the limiting member 31 to cover the guide groove.

[0057] Please refer to Figure 8 and Figure 10 Specifically, the peripheral wall of the limiting portion 311 is provided with a protruding plate 3112 facing the first support bar 312, and the protruding plate 3112 and the peripheral wall of the limiting portion 311 form a first recess 311a, and the second support bar 322 is movably arranged in the first recess 311a. Please refer to Figure 7 The fixing member 33 is provided with a second recess 33a facing the limiting member 31, and the second recess 33a and the first recess 311a are connected to form a guide groove, and the second recess 33a is used to avoid the second support bar 322 and the peripheral wall of the limiting portion 311. The protruding plate 3112 can separate the second support bar 322 and other components to avoid interference with the lifting movement of the second support bar 322. Since the second support bar 322 has a certain thickness, the guide groove needs to provide a width for the second support bar 322 to pass through. By connecting the first recess 311a and the second recess 33a to form a guide groove for the lifting movement of the second support bar 322, the occupied space of the limiting member 31 and the fixing member 33 can be reduced.

[0058] In some embodiments, please refer to Figure 7 The bottom of the fixing member 33 protrudes towards the rotating sleeve 4 to form a first protruding portion 331, please refer to Figure 13The top end of the rotating sleeve 4 protrudes towards the fixed part 33 to form a second protrusion 42, which is used to rotate against the first protrusion 331 to rotate the rotating sleeve 4 to the unlocking position D and / or the locking position L when the rotating sleeve 4 rotates relative to the sleeve 1. The first protrusion 331 of the fixed part 33 cooperates with the second protrusion 42 of the rotating sleeve 4 to provide a better hand feeling when the rotating sleeve 4 is rotated, thereby further improving the user experience. When the user wants to operate the rotating sleeve 4 to switch between the locking position L and the unlocking position D, the second protrusion 42 can rotate against the two sides of the first protrusion 331 due to the fixed rotation path of the second protrusion 42 relative to the first protrusion 331. The mutual abutment can cause the rotating sleeve 4 to produce a noticeable jamming effect during rotation, and the user can determine whether it is rotated to the correct position according to whether the jamming touch is produced or not. For example, the first protrusion 331 has opposite first and second sides. When the rotating sleeve 4 rotates counterclockwise relative to the sleeve 1, the second protrusion 42 rotates to abut against the first side to rotate to the locking position L. When the rotating sleeve 4 rotates clockwise relative to the sleeve 1 to make the second protrusion 42 abut against the second side, it rotates to the unlocking position D.

[0059] The ignition gun 100 needs to be provided with a safety switch structure to prevent accidental touch or improve safety during transportation. Currently, the safety of the ignition gun 100 is usually realized by the following structure: a button type safety switch is provided on the gun body, which always locks the ignition switch without external force to act, so that the ignition switch cannot be actuated and is safe. This safety method needs to open a slot on the ignition gun 100 and add accessories, which destroys the product appearance, has a complex structure, is easy to damage, and needs to frequently replace accessories.

[0060] Please refer to Figure 2 , Figure 4 and Figure 6 The ignition gun 100 of the embodiment of the present application does not need to be provided with a safety switch accessory, and can maintain a closed state when not in use. In some embodiments, the ignition device further comprises a push button 22, which is arranged in the sleeve 1. The push button 22 is the ignition switch of the ignition gun 100, and the push button 22 is lowered to open the ignition device. The limiting part 311 of the limiting part 31 is connected to the push button 22, and the limiting part 311 is clamped between the abutting part 321 and the push button 22. Please refer to Figure 3 and Figure 5 The push button 22 is provided with an opening 221, the abutting part 321 is provided with a protruding rib 3211, and the limiting part 311 is provided with a curved rib 3111 towards the position of the abutting part 321 and the opening 221. Please refer to Figure 3When the rotating sleeve 4 rotates to the locking position L, the protruding rib 3211 drops to abut against the bending rib 3111, so that the bending rib 3111 protrudes toward one side of the opening 221 and clamps the opening 221, and the knob 22 is clamped by the bending rib 3111 and cannot drop. When an external force is applied to the knob 22, the knob 22 cannot be opened because the knob 22 is clamped, and the ignition device is maintained in a closed state to achieve safety. Please refer to Figure 5 When the rotating sleeve 4 rotates to the unlocking position D, the protruding rib 3211 rises to release the bending rib 3111, so that the bending rib 3111 is away from the opening 221, and at this time the knob 22 is not clamped and can be dropped by an external force, and pressing the knob 22 can open the ignition device. Thus, rotating the rotating sleeve 4 to the locking position L can achieve the safety function, and no additional accessories are needed, the protruding rib 3211 and the bending rib 3111 have a simple structure, are arranged inside the sleeve 1, are not easy to be damaged, maintain the product appearance, and make the product more compact and beautiful.

[0061] In some embodiments, please refer to Figure 2 and Figure 14 The knob 22 is provided with a through hole 222 at the top, and the barrel 21 is movably arranged in the knob 22 through the through hole 222. Please refer to Figure 15 The barrel 21 is provided with a first clamping portion 211, the abutting portion 321 is provided with a second clamping portion 3212, and the second clamping portion 3212 is clamped with the first clamping portion 211. Thus, the barrel 21 and the knob 22 are both arranged in the space in the height direction of the ignition gun 100, so that the structure is more compact.

[0062] Further, please refer to Figure 15 In some embodiments, the ignition device further comprises a gun head 23 arranged in the barrel 21, the gun head 23 comprises a side wall 231 and an outer peripheral wall 232 connected with the side wall 231, the outer peripheral wall 232 is arranged close to the first clamping portion 211, the side wall 231 is provided with a third clamping portion 2311, the second clamping portion 3212 comprises a first part 3212a and a second part 3212b connected by bending, the first part 3212a is connected with the third clamping portion 2311, and the second part abuts against the bottom end of the outer peripheral wall 232 and is clamped with the first clamping portion 211 of the barrel 21. Please refer to Figure 2 The inside of the gun head 23 is used for arranging components such as a fire needle 24 and a fire spring 25, and the side wall 231 and the outer peripheral wall 232 isolate the above components from the barrel 21, reduce the interference of the external environment of the barrel 21 on ignition, and can reduce the overheating of the barrel 21 and reduce the risk of scalding.

[0063] Please refer to Figure 2 , Figure 4 and Figure 6The sleeve 1 of the ignition gun 100 also includes a pry plate 26, an air outlet valve 27, a piezoelectric 28, a storage tank 29, an air guide pipe, a wire, and the like. Specifically, one end of the air guide pipe is in communication with the ignition needle 24, and the other end is connected to the valve port of the air outlet valve 27 of the storage tank 29. The pry plate 26 is used to control the opening and closing of the air outlet valve 27 of the storage tank 29. The knob 22 is sleeved on the top of the piezoelectric 28, the piezoelectric 28 is connected to the ignition needle 24 through the wire, and the knob 22 is used to abut against the pry plate 26.

[0064] The use principle of the ignition gun 100 provided by the embodiment of the present application will be described in detail below. Figure 4 When the user needs to use the ignition gun 100 to ignite, the rotating sleeve 4 can be rotated clockwise to the unlocking position D, the first boss 3221 of the pushing part 32 rises along the threaded structure 41 on the rotating sleeve 4, the pushing part 32 pushes the barrel 21 to rise, at the same time, the protruding rib 3211 on the abutment part 321 of the pushing part 32 rises, away from and releases the curved rib 3111 of the limiting part 311 of the limiting part 31, so that the curved rib 3111 is away from the opening 221 on the knob 22.
