Referring to fig. 1-7, in one embodiment, an ignition gun 10 is provided that includes an ignition device 110, a housing 300, a sleeve 400, and a button 500. Wherein the housing 300 is hollow inside and serves to carry the ignition device 110, the sleeve 400 and the button 500. The ignition device 110 is disposed within the housing 300 and is used to perform an ignition function. The button 500 is movably provided on the housing 300 and is used to operate the ignition device 110 to be turned on and off. The sleeve 400 is rotatably sleeved on the button 500, and the sleeve 400 can rotate to a locking position L and an unlocking position D relative to the button 500. The sleeve 400 is used to limit the movement of the button 500 when in the locking position L, and the button 500 is movable relative to the ignition device 110 to control the on/off of the ignition device 110 when the sleeve 400 is in the unlocking position D.

Specifically, the sleeve 400 is provided with a fixing rib 430 at a side facing the housing 300, and when the sleeve 400 is at the locking position L, the fixing rib 430 may abut and catch the button 500 to limit the movement of the button 500. With the sleeve 400 in the unlocked position D, the button 500 can move relative to the ignitor 110. Among them, the locking position L may include a first locking position L1 and a second locking position L2. When the sleeve 400 is in the first locking position L1, the fixing rib 430 catches the push button 500 to maintain the push button 500 at a position where the ignition device 110 is turned off. When the sleeve 400 is in the second locking position L2, the fixing rib 430 catches the push button 500 to keep the push button 500 at a position where the ignition device 110 is started.

When the user operates the sleeve 400 to rotate to the unlock position D relative to the button 500, the user can select either the operation button 500 to a position where it activates the ignition device 110 to achieve ignition or the operation button 500 to a position where it deactivates the ignition device 110 to achieve ignition. In other words, the user can easily and quickly switch between the ignition state and the extinguishing state of the ignition gun 10 according to his or her own needs.

When the user operates the button 500 to the position where the user starts the ignition device 110, the sleeve 400 is rotated to the second locking position L2 relative to the button 500 to lock the button 500, so that the ignition device 110 can be maintained in the starting state, i.e. the user does not need to hold the button 500 all the time to keep the ignition device 110 in the starting state, and the operation is more convenient.

When the user operates the button 500 to its position for turning off the ignition device 110, the re-operable sleeve 400 is rotated to the first locking position L1 with respect to the button 500 to catch the button 500, so that the ignition device 110 is maintained in the turned-off state. This prevents the user from accidentally touching the button 500 to activate the ignition device 110, which improves the safety of the squib.

It should be noted that, in the process of rotatably sleeving the sleeve 400 on the button 500, the original product shape of the ignition gun 10 is not damaged. This may make the overall shape of the ignition gun 10 more compact and aesthetically pleasing.

Referring to fig. 1 and 2, the housing 300 may further have a control opening 302, the button 500 is disposed through the housing 300 via the control opening 302, and the button 500 can extend and contract relative to the inlet direction of the control opening. The button 500 may be extended in the inlet direction of the control port 302 to approach and activate the ignition 110, and the button 500 may be retracted in the inlet direction of the control port 302 to move away from and deactivate the ignition 110.

For example, in the embodiment shown in fig. 2, the ignition gun 10 may further include a pilot pin 111, an air duct 112, a pry plate 113, a magazine 200, and a driver 600 disposed inside the housing 300. Wherein, the storage tank 200 is arranged in the housing 300, fuel is stored in the storage tank 200, and the top of the storage tank 200 is provided with an air outlet valve 201. The transmission member 600 is rotatably connected to the inside of the housing 300, and the transmission member 600 is located between the ignition device 110 and the button 500. The ignition device 110 may include a piezoelectric stack 114, a resilient piezoelectric cap 115, and a wire (not shown).

Specifically, the pilot needle 111 penetrates the housing 300, an outlet of the pilot needle 111 is located outside the housing 300, one end of the air duct 112 is communicated with the pilot needle 111, the other end of the air duct is connected with a valve port of the air outlet valve 201 of the stock chest 200, and the pry plate 113 is used for controlling the opening and closing of the air outlet valve 201 of the stock chest 200. The elastic piezoelectric cap 115 is sleeved on the top of the piezoelectric group 114, the piezoelectric group 114 is connected to the firing pin 111 through a wire, and the elastic piezoelectric cap 115 is used for connecting and driving the pry plate 113. The transmission member 600 is disposed between the button 500 and the elastic piezoelectric cap 115, one end of the transmission member 600 abuts against the button 500, and the other end of the transmission member 600 abuts against and is used for pushing the elastic piezoelectric cap 115. When the sleeve 400 is in the unlocked position D, the user operable button 500 extends in the direction of the entrance of the control port 302 to close the ignition device 110. In the process, one end of the button 500 extending into the casing 300 abuts against and pushes the transmission member 600, the transmission member 600 pushes the elastic piezoelectric cap 115 to enable the piezoelectric set 114 to generate current, and the elastic piezoelectric cap 115 synchronously drives the pry plate 113 to open the gas outlet valve 201 so as to transmit the fuel in the storage tank 200 to the firing pin 111 through the gas guide tube 112. Meanwhile, the piezoelectric set 114 transmits the generated current to the ignition needle 111 through a wire, and the ignition needle 111 generates a spark to ignite the fuel. At this time, the ignition device 110 is in an activated state.

When the user operates the button 500 to retract in the inlet direction of the control port 302 away from the ignition device 110, the elastic piezoelectric cap 115 is automatically reset. At this time, the air outlet valve 201 of the accumulator 200 is closed, and the piezoelectric set 114 does not generate current, i.e., the ignition device 110 is in a closed state.

Referring to fig. 2, the ignition gun 10 may further include an elastic member 700 disposed in the housing 300, and the elastic member 700 abuts against the button 500 to make the button 500 have a tendency to move away from the ignition device 110. For example, in the embodiment shown in fig. 2 and 7, the elastic member 700 may be a spring, which abuts against an end of the button 500 extending into the housing 300 below. With the sleeve 400 in the unlocked position D, a user may manually depress the button 500 in the direction of the entrance of the control port 302 to access and activate the ignition device 110. When the user releases his hand, the button 500 is automatically moved away from and turns off the ignition device 110 by the elastic force of the elastic member 700. Therefore, the elastic member 700 improves the convenience of the user in operation, and the user has a better hand feeling in the process of operating the button 500, thereby further improving the user experience.

Referring to fig. 3 to 7, the button 500 may be provided with a stopper rib 510 at a side facing the fixing rib 430. When the sleeve 400 is in the locking position L, the fixing rib 430 can abut against and block the limiting rib 510, and when the sleeve 400 is in the unlocking position D, the fixing rib 430 leaves the movement path of the limiting rib 510.

Specifically, in the embodiment shown in fig. 5, when the sleeve 400 is in the first lock position L1, the ignition device 110 is in the off state, and the fixing rib 430 is located on the side of the restricting rib 510 close to the ignition device 110. Therefore, when the button 500 tends to approach to activate the ignition device 110, the stopper rib 510 of the button 500 is restricted by the fixing rib 430 so that the button 500 cannot approach and activate the ignition device 110, thereby keeping the ignition device 110 in the off state all the time.

In the embodiment shown in fig. 6, when the sleeve 400 is in the second lock position L2, the ignition device 110 is in the activated state, and the fixing rib 430 is located on the side of the restricting rib 510 away from the ignition device 110. Therefore, when the button 500 tends to move away to turn off the ignition device 110, the stopper rib 510 of the button 500 is restricted by the fixing rib 430 so that the button 500 cannot move away to turn off the ignition device 110, thereby keeping the ignition device 110 in the on state.

In the embodiment shown in fig. 7, when the sleeve 400 is in the unlocking position D, the fixing rib 430 is away from the movement path of the limiting rib 510, i.e., the fixing rib 430 does not limit the movement of the limiting rib 510, i.e., the button 500 can be either close to the ignition device 110 or far from the ignition device 110.

Referring to fig. 3 and 8, the housing 300 may further have a limiting sliding groove 310 along an inlet direction of the control port 302, and the limiting rib 510 of the button 500 may extend into the limiting sliding groove 310 and slide along the limiting sliding groove 310. Since the limiting rib 510 slidably disposed on the limiting sliding groove 310 is limited by the groove wall of the limiting sliding groove 310, the limiting rib 510 will not be separated from the limiting sliding groove 310 during movement, i.e. the limiting sliding groove 310 has a guiding function for the movement of the button 500. Thus, the button 500 has a fixed movement path when moving relative to the ignition device 110, i.e., the stopper rib 510 has a fixed movement path. This ensures that the fixing ribs 430 of the fixing cover 400 can accurately abut against and catch the position restricting ribs 510 on the movement path of the position restricting ribs 510 when the fixing cover 400 is in the locking position.

Further, in the embodiment shown in fig. 3 to 7, the number of the limiting sliding grooves 310 and the limiting ribs 510 is two. The first limiting sliding groove 311 and the second limiting sliding groove 312 on the housing 300 are arranged at an interval, and the first limiting rib 511 and the second limiting rib 512 on the button 500 are arranged opposite to each other. The first limiting rib 511 can extend into the limiting sliding groove 311 and slide along the limiting sliding groove 311, and the second limiting rib 512 can extend into the limiting sliding groove 312 and slide along the limiting sliding groove 312. In other words, the first and second limiting sliding

grooves

311 and 312 respectively guide the movement of the button 500 from both sides of the button 500, thereby improving the movement stability of the button 500. Correspondingly, the sleeve 400 may also have a first fixing rib 431 and a second fixing rib 432 formed on the inner side thereof in a protruding manner and arranged at an opposite interval. When the sleeve 400 rotates to the locking position L relative to the button 500, the first fixing rib 431 and the second fixing rib 432 on the sleeve 400 are respectively used for abutting and clamping the first limiting rib 511 and the second limiting rib 512 on the button 500, that is, the first fixing rib 431 and the second fixing rib 432 respectively clamp the button 500 from two sides of the button 500, so that the button 500 is better locked.

Referring to fig. 3, a first anti-slip rib 520 may be disposed at one end of the button 500 extending into the casing 300 and facing one side of the casing 300, and a first protruding edge 320 is protruded from one side of the casing 300 facing the first anti-slip rib 520, and the first protruding edge 320 can abut against the first anti-slip rib 520 to clamp the button 500.

For example, in the embodiment shown in fig. 3, the first ledge 320 of the housing 300 is disposed around the button 500, and the first ledge 320 is located above the first anti-slip rib 520, i.e. the first ledge 320 is located on a side of the first anti-slip rib 520 facing away from the ignition device 110. When the button 500 retracts along the inlet direction of the control port 302, the first anti-slip rib 520 moves to the lower portion of the first protruding edge 320, namely, the first protruding edge 320 faces away from one side of the control port 302, the first anti-slip rib 520 is abutted and clamped by the first protruding edge 320, namely, the movement of the button 500 is limited by the first protruding edge 320, the button 500 cannot exit from the control port 302, and the matching firmness of the button 500 and the shell 300 is further improved.

Referring to fig. 1, 2 and 3, the sleeve 400 is spaced apart from the button 500, and the sleeve 400 is rotatably sleeved on an end of the housing 300 where the control opening 302 is formed. The limiting rib 510 can penetrate through the limiting sliding groove 310 and protrude out of the surface of the housing 300, so that when the sleeve 400 rotates to the locking position L relative to the button 500, the fixing rib 430 on the sleeve 400 can abut against the limiting rib 510.

Further, referring to fig. 3, 4 and 8, the housing 300 has a second protruding edge 350 protruding outward around the control opening 302, the sleeve 400 has a second anti-slip rib 420 on a side facing the second protruding edge 350, and the second protruding edge 350 can abut against the second anti-slip rib 420 to lock the sleeve 400.

For example, in the embodiment shown in fig. 3 and 8, the second ledge 350 is located above the second anti-trip rib 420, that is, the second ledge 350 is located on the side of the second anti-trip rib 420 facing away from the ignition device 110. When the sleeve 400 has a tendency to disengage from the housing 300, the second anti-slip rib 420 is abutted and caught by the second ledge 350. Therefore, the movement of the sleeve 400 is restricted by the second ledge 350, and the sleeve 400 is not separated from the housing 3 and can rotate under the second ledge 350. This arrangement allows the sleeve 400 to rotate to the locking position L and the unlocking position D with respect to the push button 500 to perform the function of the safety switch, while maintaining the function of fixing the housing 300. This makes this burning torch 10 keep the product appearance simple and pleasing to the eye, reduce the manufacturing product simultaneously, still can have both the convenience of operation and security concurrently.

Referring to fig. 8, the housing 300 may further include a positioning boss 330 and an elastic boss 340. The positioning boss 330 has locking and unlocking

sides

331 and 332 disposed opposite each other in the circumferential direction along the control port 302. The positioning boss 330 is located on the moving path of the fixing rib 430, and the elastic boss 340 is located on the moving path of the second anti-slip rib 420. The positioning bosses 330 and the elastic bosses 340 are arranged on the housing 300 at intervals along the axial direction of the control port 302, and the positioning bosses 330 are located below the elastic bosses 340, that is, the positioning bosses 330 are closer to the ignition device 110 than the elastic bosses 340. The fixing ribs 430 and the second anti-slip ribs 420 are arranged on the inner circumferential surface of the sleeve 400 at intervals along the axial direction of the sleeve 400, and the fixing ribs 430 are located below the second anti-slip ribs 420, that is, the fixing ribs 430 are closer to the ignition device 110 relative to the second anti-slip ribs 420.

Specifically, in the embodiment shown in fig. 8, the housing 300 is marked with a locking symbol 303 and an unlocking symbol 304, and the sleeve 400 is marked with an indication arrow 410.

When the user operates the sleeve 400 to rotate relative to the button 500, and the fixing rib 430 on the sleeve 400 is blocked on the locking side 331 of the positioning boss 330, one side of the fixing rib 430 is abutted against one side of the limiting rib 510 facing toward or away from the ignition device 110 to limit the movement of the limiting rib 510, that is, the sleeve 400 is located at the locking position L, and the indication arrow 410 on the sleeve 400 points to the locking symbol 303.

When the user operates the sleeve 400 to rotate relative to the button 500 and the fixing rib 430 on the sleeve 400 is caught on the unlocking side 332 of the positioning boss 330, the sleeve 400 is located at the unlocking position D, and the indication arrow 410 on the sleeve 400 points to the unlocking symbol 304. Wherein the indication arrow 410 on the sleeve 400 cooperates with the locking symbol 303 and the unlocking symbol 304 on the housing 300 to give a user a clear operation guide.

The sleeve 400 is simultaneously rotated and sleeved on the button 500 and the end of the casing 300 with the control port 302, when the sleeve 400 rotates relative to the button 500, the sleeve 400 can synchronously rotate relative to the casing 300, and the second anti-disengagement rib 420 and the fixing rib 430 on the sleeve 400 can respectively rotate relative to the elastic boss 340 and the positioning boss 330 on the casing 300, i.e. the second anti-disengagement rib 420 has a fixed motion path relative to the elastic boss 340, i.e. the fixing rib 430 has a fixed motion path relative to the positioning boss 330. It should be noted that, since the positioning bosses 330 and the elastic bosses 340 are arranged on the housing 300 at intervals along the axial direction of the control port 302, and the fixing ribs 430 and the second retaining ribs 420 are arranged on the inner circumferential surface of the sleeve 400 at intervals along the axial direction of the sleeve 400, the fixing movement paths of the fixing ribs 430 and the second retaining ribs 420 are not the same. In other words, cooperating with the positioning boss 330 to control the movement of the stopper rib 510 is the fixing rib 430.

The second anti-slip ribs 420 of the sleeve 400 are matched with the elastic bosses 340 of the housing 300, so that a user can feel better when rotating the sleeve 400, and the user experience is further improved. For example, when the user wants to operate the sleeve 400 to switch between the locking position L and the unlocking position D, that is, during the process of rotating the sleeve 400, since the second anti-slip rib 420 has a fixed moving path relative to the elastic boss 340, the second anti-slip rib 420 can abut against the side of the elastic boss 340 facing away from the button 500, and the friction force between the second anti-slip rib 420 and the elastic boss 340 can make the sleeve 400 generate a significant locking effect during the rotation process. When the sleeve 400 rotates to the locking position L or the unlocking position D, the second anti-slip rib 420 does not abut against the side of the elastic boss 340 opposite to the button 500, i.e., the second anti-slip rib 420 is separated from the elastic boss 340, and the locking effect is not generated. In other words, the user can determine whether the sleeve 400 is rotated in place by sensing whether the rotation of the sleeve 400 has a click feeling. Therefore, such a structure may provide a better operation feeling for the user in the process of rotating the sleeve 400, and the operation feeling may also help the user to determine whether the sleeve 400 is rotated in place.

Referring to fig. 1 and 2, the ignition gun 10 may further include a gun head 810, a fastening sleeve 820, a barrel 830, a shroud 840, and a rear case 850. The gun head 810, the fastening sleeve 820 and the gun barrel 830 are all sleeved on the shell 300 from one end of the shell 300, which is provided with the ignition needle 111. The case 840 is inserted into the housing 300 from the bottom thereof, and the rear case 850 is then snapped into the housing 300 from below the case 840 to insert the case 840. Due to the structural arrangement, the overall structure of the ignition gun 10 is firmer, the gun head of the ignition gun 10 can be well protected, and the service life of the ignition gun 10 is further prolonged.
