DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-4 As shown, the igniter of the utility model embodiment includes: a shell 10, an ignition tube 20, a safety lock 30, a normally open switch 40 and an electric shock switch 50, wherein the ignition tube 20 is arranged at the front end of the shell 10, and a heating device (not shown in the figure) is arranged in the ignition tube 20; the safety lock 30 includes a safety lock button 31 and a safety lock reset spring 32, the safety lock button 31 includes a button front end 311, a button connecting part 312, a safety lock spring column 313 and a button end 314, the two ends of the button connecting part 312 are fixedly connected to the button front end 311 and the button end 314 respectively, a limiting column 315 is arranged on the side of the button connecting part 312, and the safety lock spring column 313 is One end is connected to the front end 311 of the button or the end 314 of the button, and the safety lock reset spring 32 is sleeved on the safety lock spring column 313; the normally open switch 40 includes a seesaw 41 and a switch reset spring 42, the seesaw 41 includes a movable rod 411 and a first boss 412, a second boss 413 and a third boss 414 arranged on the movable rod 411, one end of the switch reset spring 42 is sleeved on the second boss 413, and the other end of the switch reset spring 42 is sleeved on the switch spring column 11 on the inner side of the shell 10 and abuts against the first rib 12 on the inner side of the shell 10; the electric shock switch 50 is electrically connected to the heating device, and the electric shock switch 50 includes a contact 51 and a movable contact 52.

[0027] When the safety lock button 31 is in a released state, the limiting column 315 of the button connecting part 312 abuts against the first protrusion 412; when the safety lock button 31 is in a pressed state, the button end 314 abuts against the inner wall of the shell 10, and the second rib 13 on the inner side of the shell 10 abuts against the safety lock reset spring 32; when the rocker 41 is in a pressed state, one side of the contact 52 abuts against the third protrusion 414, and the other side of the contact 52 is connected to the contact 51.

[0028] It is understandable that, when the safety lock button 31 is in the released state, the limit column 315 of the button connection part 312 abuts against the first protrusion 412, so that the seesaw 41 cannot move upward to abut against the contact 52. Only when the safety button 31 is in the pressed state, the seesaw 41 can be pressed, so that the contact 52 is connected with the contact 51, so that the power supply can supply power to the heating device through the electric shock switch 50. When the ignition tube 20 of the igniter of the embodiment of the present invention is directed toward the flammable material, the safety button 31 and the seesaw 41 are pressed, and the heating device is powered on, the flammable material can be ignited by the heat generated by the heating device to achieve the ignition function.

[0029] The igniter of the embodiment of the present invention provides a second rib 13 on the inner side of the shell 20 for abutting against the safety lock reset spring 32 so that the safety lock 30 can be automatically reset, and a limit column 315 is provided on the button connection portion 312 for abutting against the first protrusion 412 when the safety button 31 is pressed, so that the operator must press the safety button 31 and the rocker 41 to power on the heating device, which can avoid safety hazards caused by operator misoperation; the switch reset spring 42 is provided so that the normally open switch 40 can be automatically reset when the rocker 41 is in a released state, effectively avoiding long-term ignition caused by negligence and improving the safety of the igniter; when the operator does not need to continue ignition, the ignition can be stopped by releasing the rocker 41, so that the operator can control the ignition time more directly and accurately.

[0030] Depend on Figure 4 It can be seen that in one embodiment of the present invention, a support column 14 and a limiting structure 15 are provided inside the housing 10, one end of the movable rod 411 is sleeved on the support column 14, and the other end of the movable rod 411 is placed in the limiting structure 15, and can move between the first position and the second position defined by the limiting structure 15. When the seesaw 41 is in a released state, the movable rod 411 is in the first position defined by the limiting structure 15; when the seesaw 41 is in a pressed state, the movable rod 411 rotates around the support column 14 and moves upward, so that the movable rod 411 is in the second position defined by the limiting structure 15, and the third protrusion 414 on the movable rod 411 abuts against the contact 52.

[0031] like Figure 3 As shown, in one embodiment of the present invention, there may be two safety lock spring columns 313, the first safety lock spring column is connected to the front end 311 of the button, and the second safety lock spring column is connected to the end 314 of the button. Since the first safety lock spring column is not connected to the second safety lock spring column, the safety lock reset spring 32 can be directly put in or taken out from the safety lock 30 when assembling the igniter, which is convenient for assembly and subsequent maintenance.

[0032] In other specific embodiments, according to user needs, only one safety lock spring column can be set, one end of the safety lock spring column is connected to the front end of the button, and the other end of the safety lock spring column is connected to the end of the button. This embodiment is not limited to this.

[0033] When only one end of the safety lock spring column 313 is connected to the key front end 311 or the key end 314, a baffle 316 (such as Figure 3 As shown), the safety lock reset spring 32 is prevented from escaping from the safety lock spring column 313, causing the safety lock 30 to be unable to reset and fail.

[0034] like Figure 5 As shown, in one embodiment of the present invention, the heating device may be a heating wire 60 .

[0035] In one embodiment of the present invention, in order to achieve better heat dissipation, the ignition tube 20 may be a metal cover (such as an aluminum alloy cover, etc.), and the heating wire 60 may be wrapped with insulating material to avoid direct contact between the heating wire and the ignition tube 20.

[0036] Specifically, a ventilation hole is provided on the ignition tube 20, and the igniter may further include a motor 70 and a fan 80. When the contact 52 is electrically connected to the contact 51, the motor 70 is energized to provide power to the fan 80 (eg, Figure 5 As shown), the fan can blow the air heated by the electric heating wire 60 toward the flammable material that needs to be ignited (such as coal, flammable wood, etc. contained in the barbecue grill).

[0037] like Figure 5 As shown, in one embodiment of the utility model, the igniter may further include: a mode switching module 90, the mode switching module 90 includes a mode switching switch, and the mode switching switch is used to control whether the heating device is heated. When the heating device is heated, the igniter can be used for ignition; when the heating device is not heated and only the fan is working, the igniter can provide room temperature wind for the ignited flammable material to assist combustion.

[0038] Preferably, the mode switching switch includes a room temperature switch and a heating switch. When the room temperature switch is closed, the heating device does not generate heat; when the heating switch is closed, the heating device generates heat. Separately providing the room temperature switch and the heating switch can prevent operators from making erroneous operations due to not being able to distinguish how the mode switching switch controls the heating device, thereby improving the operating experience.

[0039] In one embodiment of the present invention, the mode switching module 90 further includes a mode display unit, which is used to display whether the heating device is heating, so that the operator can understand the working state of the igniter more intuitively.

[0040] According to the igniter of the embodiment of the utility model, by providing an automatically resettable safety lock and a limit column at the button connection part, the operator must press the safety button and the seesaw to power on the heating device, which can avoid safety hazards caused by operator misoperation; by providing an automatically resettable normally open switch, long-term ignition caused by negligence can be effectively avoided, thereby improving the safety of the igniter; when the operator does not need to continue ignition, the ignition can be stopped by releasing the seesaw, so that the operator can control the ignition time more directly and accurately.
