Since the starting part in the friction ignition mechanism 300 is arranged outside the covering area of ​​the machine cover 400, the user can directly push the starting part of the friction ignition mechanism 300 to drive the first engaging portion 330 to move to separate from the second engaging portion 410. At this time, the machine cover 400 is automatically opened under the action of the first elastic reset member 500. At this time, continue to maintain the pushing posture, and then rotate the starting part of the friction ignition mechanism 300, so that the friction ignition mechanism 300 can generate sparks to ignite the ignition part 110 located on one side of the friction ignition mechanism 300, thereby achieving the effect of opening the machine cover 400 and ignition with one button, and the entire ignition process is simpler and the operation is smoother.

[0037] Optionally, a combustible gas or liquid such as alcohol or butane may be provided in the fuel tank 100 .

[0038] Optionally, the ignition portion 110 is an ignition core or an openable combustible gas hole, etc., which mainly serves to guide the fuel in the fuel tank 100; preferably, the ignition portion 110 is an ignition core, and a bundling member such as a metal wire can be provided in the ignition core to bundle it.

[0039] Optionally, a cover cap is provided on the machine cover 400 corresponding to the ignition part 110 to extinguish the flame on the ignition part 110 when the machine cover 400 is closed.

[0040] In an optional embodiment, the first clamping portion 330 includes a first wedge surface 331 and a first hook surface 332; the second clamping portion 410 includes a second wedge surface 411 and a second hook surface 412; the second wedge surface 411 is suitable for cooperating with the inclined surface of the first wedge surface 331; the cover 400 has a closed state and an open state, in the closed state, the second hook surface 412 abuts against the first hook surface 332; in the open state, the second hook surface 412 is separated from the first hook surface 332.

[0041] In this embodiment, if Figure 8 As shown, in the closed state, the second hook surface 412 has a tendency to rotate upward under the drive of the machine cover 400 and the first elastic reset member 500 to hook the first hook surface 332, which is equivalent to the first hook surface 332 blocking the movement trend of the machine cover 400 to open upward; when the machine cover 400 needs to be opened, the friction ignition mechanism 300 is pushed, and the first hook surface 332 is driven away from the second hook surface 412 by the friction ignition mechanism 300. When the first hook surface 332 is completely separated from the second hook surface 412, the machine cover 400 automatically opens under the elastic force of the first elastic reset member 500. Open; when the hood 400 needs to be closed, the first hook surface 332 should be reset to the initial state, pushing the hood 400 to rotate toward the fuel tank 100, and the second wedge surface 411 on the hood 400 first abuts against the first wedge surface 331 and pushes it to one side to compress the first elastic reset member 500 until the second wedge surface 411 completely passes over the first wedge surface 331 and the first hook surface 332. At this time, the first elastic reset member 500 drives the first wedge surface 331 and the first hook surface 332 to reset, thereby cooperating with the second hook surface 412 to lock the hood 400 again.

[0042] In an optional embodiment, the fixing seat 200 is fixed to the fuel tank 100 in a detachable connection to facilitate disassembly and assembly; preferably, the fixing seat 200 is inserted into a slot on the fuel tank 100 by a pin or is connected to the fuel tank 100 by screws.

[0043] In an optional embodiment, as shown in the figure, the first elastic return member 500 is an elastic telescopic rod, the first end of the elastic telescopic rod is connected to the inner wall of the machine cover 400, and the second end of the elastic telescopic rod is connected to the fuel tank 100 and / or the fixed seat 200 to provide sufficient return force to the machine cover 400 when needed.

[0044] In an optional embodiment, the first elastic return member 500 is a torsion spring disposed on the hinge axis between the engine cover 400 and the fuel tank 100 .

[0045] In an optional embodiment, the friction ignition mechanism 300 includes a sparking wheel assembly 310 and a flint feeding assembly 320 connected to each other, that is, when the friction ignition mechanism 300 is pushed by an external force, the sparking wheel assembly 310 moves together with the flint feeding assembly 320; the sparking wheel assembly 310 includes a sparking wheel 311 and a rubbing wheel 312 coaxially and linked with the sparking wheel 311, and the rubbing wheel 312 is the starting part of the friction ignition mechanism 300; the rubbing wheel 312 is arranged outside the covering area of ​​the machine cover 400; the flint feeding assembly 320 includes a flint bin 321, and a loading hole 322 arranged toward the sparking wheel 311 is opened on the flint bin 321, and the loading hole 322 is used to load flint; the flint feeding assembly 320 also includes a second elastic reset member 323 to push the flint to abut the sparking wheel 311.

[0046] The usage process of this embodiment is exemplified as follows. Assuming that the initial state is the closed state of the machine cover 400, when the user needs to light a fire, the rubbing wheel 312 arranged outside the machine cover 400 is pushed. When the rubbing wheel 312 moves, it will drive the first clamping part 330 on the friction ignition mechanism 300 to separate from the second clamping part 410 on the machine cover 400, and under the action of the first elastic reset member 500, the machine cover 400 is opened; since a flint is arranged in the loading hole 322 of the flint bin 321, and the second elastic reset member 323 pushes the flint against the sparking wheel 311, and the rubbing wheel 312 is coaxially linked with the sparking wheel 311 (the linkage can be understood as the sparking wheel 311 is driven to rotate synchronously when the rubbing wheel 312 rotates), after pushing the rubbing wheel 312 to open the machine cover 400, rotating the rubbing wheel 312 can make the sparking wheel 311 rotate and rub the flint to generate sparks to ignite the ignition part 110.

[0047] Further, a rotation limit assembly is provided on the fixed seat 200 and / or the fuel bin 100, and the rotation limit assembly serves to limit the opening angle of the cover 400; further, the rotation limit assembly includes a first limit member 240 and a second limit member; the first limit member 240 extends from the end of the fixed seat 200 away from the spark wheel 311, and the second limit member (not shown) extends from the hinged end of the cover 400; when the cover 400 is rotated to open, the second limit member (not shown) thereon will be blocked by the first limit member 240 to prevent the cover 400 from rotating to open at an excessive angle, and to prevent the cover 400 from being bumped or scratched with the fixed seat 200. Optionally, the opening angle is 45 to 80 degrees, so as to fully open the ignition part 110 while ensuring a shorter closing stroke of the cover 400 and reducing the impact force on the rotating member, so as to prevent damage.

[0048] In an optional embodiment, the fixed seat 200 is provided with a guide hole 220 corresponding to the flint bin 321, and the flint bin 321 is inserted into the guide hole 220 for guided movement therein to prevent the rubbing wheel 312 from being offset during the process of pushing the rubbing wheel 312; the fixed seat 200 and / or the fuel bin 100 are provided with a stroke limiting structure 600 to limit the movement stroke of the flint bin 321, to prevent the flint bin 321 from being separated from the guide hole while ensuring the stability and reliability of the movement process; the second elastic reset member 323 is provided in the guide hole 220, and the second elastic reset member 323 can be an elastic member such as a spring or an elastic telescopic rod; The first end of the flint in the bin 321 abuts against the second elastic reset member 323, and the second end of the flint is suitable for abutting against the sparking wheel 311; the second elastic reset member 323 pushes the flint to the sparking wheel 311 to ensure that the sparking wheel 311 can rub against the flint to produce sparks when it rotates; at the same time, because the flint abuts against the sparking wheel 311, it is equivalent to that the second elastic reset member 323 can also give a reset force to the entire friction ignition mechanism 300. After the rubbing wheel 312 is pushed to produce displacement and the thrust is withdrawn, the second elastic reset member 323 can drive the rubbing wheel 312 and the components connected thereto to reset.

[0049] In an optional embodiment, the sparking wheel 311 and the rubbing wheel 312 are connected via a transition shaft 313 to ensure the coaxiality and connection stability between the two; the flint bin 321 has an extension section 324 and a vertical connecting hole 3241 is provided on the extension section 324 corresponding to the transition shaft 313, and the flint bin 321 is sleeved on the outer side of the transition shaft 313 through the connecting hole 3241; in this way, when the rubbing wheel 312 is pushed in use, the rubbing wheel 312 drives the sparking wheel 311 to move through the transition shaft 313, and at the same time drives the flint bin 321 to move and compress the second elastic reset member 323 through the connecting hole 3241 on the extension section 324, thereby realizing the ignition movement process of the friction ignition mechanism 300; when the rubbing wheel 312 is released, the second elastic reset member 323 drives the flint bin 321, the sparking wheel 311 and the rubbing wheel 312 to reset, thereby realizing the reset movement process of the friction ignition mechanism 300.

[0050] In an optional embodiment, the cross section of the guide hole 220 is polygonal, and the shape of the flint bin 321 is adapted to the internal shape of the guide hole 220, so that the flint bin 321 can slide in the guide hole 220; preferably, Figure 4 As shown, the cross section of the guide hole 220 is rectangular, so as to achieve the effects of wear resistance, easy processing, and more reliable and stable movement process.

[0051] In an optional embodiment, the guide hole 220 is selected to be a circular hole, and the flint magazine 321 is cylindrical so as to move in the guide hole 220 .

[0052] In an optional embodiment, the guide hole 220 has a first limiting surface on the side facing the friction ignition mechanism 300 , and the flint magazine 321 has a second limiting surface to abut against the first limiting surface when in use, thereby limiting the length of the flint magazine 321 entering the guide hole 220 .

[0053] In an optional embodiment, the travel limit mechanism 600 includes a groove 610 disposed on the fuel bin 100 or the fixing seat 200 and a protrusion 620 connected to the flint bin 321, wherein the protrusion 620 is adapted to move in the groove 610; further, as Fig. 9 As shown, the groove 610 is a circular groove and the protrusion 620 is a cylindrical block to facilitate sliding fit between the two.

[0054] In an optional embodiment, the end of the transition shaft 313 close to the rubbing wheel 312 is the large end, and the end of the transition shaft 313 close to the spark wheel 311 is the small end; the diameter of the small end is smaller than the diameter of the large end; there is a gap between the transition shaft 313 and the connecting hole 3241; if the movement of the rubbing wheel 312 is translational, then the shape of the transition shaft 313 is not important; but if the pushing process of the rubbing wheel 312 is rotation, then the rubbing wheel 312 and the connecting hole 3241 may get stuck, therefore, the transition shaft 313 is set to have different diameters at the top and bottom and at least have some gap between it and the connecting hole 3241 to prevent the movement process from being unsmooth; for ease of understanding, as Fig. 9 As shown, the lower end of the transition shaft 313 is the large end, and the upper end of the transition shaft 313 is the small end.

[0055] In an optional embodiment, if Fig. 9 As shown, the sparking wheel assembly 310 also includes a rotating limit post 314, and the sparking wheel 311 is sleeved on the outer side of the rotating limit post 314; wherein, the outer side surface of the rotating limit post 314 limits the relative rotation between the sparking wheel 311 and the rotating limit post 314, and the sparking wheel 311 is suitable for radial movement along the rotating limit post 314; this design allows the sparking wheel 311 to be easily disassembled and removed, and at the same time, the rotating limit post 314 can ensure that the sparking wheel 311 and the rubbing wheel 312 rotate synchronously; specifically, the cross-section of the limit post 314 can be made into a polygon, such as three sides, four sides, five sides, six sides, etc., and a hole with a shape matching the outer side surface of the limit post 314 is opened in the middle of the sparking wheel 311.

[0056] In an optional embodiment, a notch 120 is provided on the outer shell of the fuel tank 100, a first spherical groove 121 is opened at the bottom of the notch 120, a first spherical protrusion 3121 is provided at the bottom end of the rubbing wheel 312 and inserted into the first spherical groove 121; a blocking cover 210 is provided on the fixed seat 200, and the blocking cover 210 presses down the sparking wheel 311 to limit the vertical movement of the sparking wheel assembly 310.

[0057] like Figure 6 As shown, a notch 120 is provided on the outer shell of the fuel bin 100 to accommodate a vertical rubbing wheel 312, and the notch 120 matches the shape of the rubbing wheel 312 but reserves a moving position for the rubbing wheel 312, thereby ensuring that the overall structure is compact and does not affect the normal operation of the friction ignition mechanism 300; the rubbing wheel 312 and the notch 120 are butted against each other by the first spherical protrusion 3121 and the first spherical groove 121, that is, the butt-fitting position of the first spherical protrusion 3121 and the first spherical groove 121 is the hinge point of the rubbing wheel 312, so that the rubbing wheel 312 can be pushed directly by pressing during use, which is easier than pushing the rubbing wheel 312 horizontally, and The design is ergonomic; it is understandable that if only this connection method is used, the rubbing wheel 312 can be pulled out directly upwards, so a blocking cover 210 is set on the fixed seat 200 to press the sparking wheel 311 to limit the upward movement of the rubbing wheel 312, and the flint bin 321 is only guided to move in the loading hole 322 and is limited by the stroke limiting structure 600, and the rubbing wheel 312 is connected to the flint bin 321, so the horizontal movement of the rubbing wheel 312 can only follow a predetermined trajectory, so that the overall structural design can operate reliably and stably; at the same time, the blocking cover 210 presses the sparking wheel 311 to prevent the sparking wheel 311 from falling off the rotating limit column 314 during use.

[0058] In an optional embodiment, the fixed base 200 and the blocking cover 210 are slidably connected, and the blocking cover 210 can be slid off the fixed base 200. After the blocking cover 210 slides off the fixed base 200, the sparking wheel 311 can be exposed, so that the sparking wheel 311 can be directly removed from the rotating limit column 314 for easy disassembly and assembly; specifically, an example is as follows: one of the sliding grooves or sliders is provided on the fixed base 200, and the other of the sliding grooves or sliders is provided on the blocking cover 210, and the sliding of the blocking cover 210 relative to the fixed base 200 is achieved through the cooperation of the sliding groove and the slider, but the end of the sliding groove is set to be open, so that the blocking cover 210 can be completely detached from the fixed base 200; further, an anti-slip portion is provided on the blocking cover 210 to increase the friction between the fingers and it during use, so as to facilitate its sliding.

[0059] In an optional embodiment, if Figure 6As shown, a positioning groove 230 is provided on the side of the fixing seat 200 facing the blocking cover 210; the blocking cover 210 is provided with an elastic protrusion 211 corresponding to the positioning groove 230, and the blocking cover 210 is positioned by the cooperation of the elastic protrusion 211 and the positioning groove 230 to prevent the blocking cover 210 from automatically sliding uncontrollably during use; the elastic protrusion 211 can be a protrusion with elasticity itself; it can also be a cooperation including a spring assembly and a positioning block, as shown in the following example, the shape of the positioning block is adapted to the shape of the positioning groove 230 The positioning block is abutted against a spring assembly in the direction away from the positioning groove 230, thereby giving the positioning block a thrust to move toward the positioning groove 230; it can be understood that at least one of the elastic protrusion 211 and the positioning groove 230 is provided with an inclined surface to facilitate the elastic protrusion 211 to disengage from the positioning groove 230; preferably, the positioning groove 230 is a spherical positioning groove, and a section of the elastic protrusion 211 inserted into the spherical positioning groove has a spherical mating surface to facilitate the elastic protrusion 211 to smoothly enter or disengage from the positioning groove 230.

[0060] In another optional embodiment, the outer shell of the fuel tank 100 has a notch, and the rubbing wheel 312 can move horizontally in the notch, and the cover is opened by horizontally pushing the rubbing wheel 312. This structural design is relatively simple and has a low production cost.
