[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0031] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0033] Reference Figures 1 to 6 , the present application proposes a plasma generating assembly for a lighter, comprising a plasma head 1, a plasma cylinder 2 and a flow guide assembly 3;

[0034] The flow guide assembly 3 and the plasma tube 2 are both hollow structures. The plasma tube 2 is connected to one end of the flow guide assembly 3. The inner wall of the plasma tube 2 and the inner wall of the flow guide assembly 3 are combined to form a cavity. The plasma head 1 passes through the other end of the flow guide assembly 3 into the cavity and does not contact the inner wall of the plasma tube 2.

[0035] The plasma head 1 is movably connected to the flow guide component 3 , and the plasma head 1 can undergo longitudinal displacement relative to the flow guide component 3 .

[0036] In this embodiment, the plasma generating assembly is used to generate a high-temperature plasma similar to a flame and ignite combustible materials through the plasma. The plasma generating assembly is electrically connected to a power supply. Specifically, the plasma head 1 is electrically connected to one pole of the power supply, and the plasma tube 2 is electrically connected to the other pole of the power supply. The power supply can be a rechargeable battery that can both store and discharge electricity, or a non-rechargeable battery that can only discharge electricity. After the power supply is connected to a transformer, the alternating current is converted into high-voltage direct current and output to power the plasma generating assembly. Since the plasma head 1 and the plasma tube 2 are not in contact and are connected and fixed by an insulating guide assembly 3, there is no conduction between the plasma head 1 and the plasma tube 2. The air between the plasma head 1 and the plasma tube 2 is ionized by the high voltage, generating a high-temperature plasma.

[0037] After the power is turned on, arcing will occur between the outer wall of the plasma head 1 and the inner wall of the plasma tube 2. The plasma head 1 includes a plasma head body 11 arranged at the upper end and an electrode lead-in portion 12 at the lower end. The plasma head body 11 is arranged at one end of the electrode lead-in portion 12, and the other end of the electrode lead-in portion 12 is located outside the cavity for electrical connection with the power supply. The plasma head body 11 is approximately a cone, and the electrode lead-in portion 12 is approximately a cylinder. The cross-sectional diameter of the upper end of the plasma tube 2 is smaller than the cross-sectional diameter of the lower end, so that when the relative position between the plasma head 1 and the plasma tube 2 changes, the distance between the outer wall of the plasma head 1 and the inner wall of the plasma tube 2 will also change, and the shortest arcing distance will change accordingly. When the arcing distance changes, the electric field strength between the plasma head 1 and the plasma tube 2 changes, so that the intensity of the generated plasma changes. Figure 2 and Figure 4 As an example, refer to the embodiment shown in Figure 2 At this time, for the plasma head 1 and the plasma tube 2, the shortest arc striking distance is the distance from the bottom end of the plasma tube 2 to the outer surface of the plasma head body 11, which is L1 shown in the figure. When adjusting the longitudinal position of the plasma head 1, refer to Figure 4 , the shortest arc striking distance changes to the distance from the lower end of the plasma tube 2 to the electrode lead-out portion 12, which is L2 shown in the figure. The length of L1 is greater than the length of L2. The longer the arc striking distance, the lower the intensity of the generated plasma. Correspondingly, the shorter the arc striking distance, the higher the intensity of the generated plasma. Users can adjust the plasma intensity as needed.

[0038] In one embodiment, the electrode lead-out portion 12 is provided with a thread (not shown in the figure) and is movably connected to the guide assembly 3 through the thread, so that the radial movement of the electrode lead-out portion 12 can be converted into axial movement in the vertical direction. The lower end of the electrode lead-out portion 12 is provided with a rotating portion 121, and the rotating portion 121 can be directly extended from the lighter. The user can directly rotate the rotating portion 121 to make the electrode lead-out portion 12 move upward or downward. In this embodiment, since the user will directly contact the rotating portion 121, the rotating portion 121 is set to an insulating material to avoid safety hazards. In another embodiment, the electrode lead-out portion 12 is completely located inside the lighter, and the rotating portion 121 includes two oppositely arranged protrusions, and a slot is formed between the two protrusions. The slot can be connected to an insulating rod or other structure, so that one end of the insulating rod is limited in the slot and the other end extends to the outside of the lighter and is movably connected to the outer shell of the lighter. The user drives the electrode lead-out portion 12 to rotate by rotating the insulating rod.

[0039] In this embodiment, the flow guide assembly 3 includes a flow guide portion 31 and a connecting portion 32. The flow guide portion 31 is arranged close to the plasma tube 2. The flow guide portion 31 is located on one side of the connecting portion 32. The flow guide portion 31 and the connecting portion 32 are both hollow structures, and the cross-sectional radius of the inner wall of the flow guide portion 31 is larger than the cross-sectional radius of the inner wall of the connecting portion 32, so that one end of the plasma tube 2 can be inserted into the flow guide portion 31, and the thread connected to the electrode lead-out portion 12 is provided on the inner wall of the connecting portion 32. A thread is provided on the outer wall of the plasma tube 2, and the plasma tube 2 can be fixed to other structures of the lighter, such as the outer shell, through the thread. During assembly, the plasma tube 2 can be rotatably connected to the flow guide portion 31 through the thread, or it can be as shown in FIG. Figure 6 As shown, an annular groove adapted to the structure of the plasma tube 2 is provided on the guide portion 31, so that the bottom wall of the plasma tube 2 abuts against the bottom wall of the groove. Since the position of the plasma tube 2 is fixed by the lighter, and the plasma head 1 is inserted into the connecting portion 32, the relative position of the plasma head 1 and the connecting portion 32 will not change when no external force is applied. After assembly, the relative position of the plasma tube 2 and the guide portion 31 is also fixed. Other fixing structures can also be provided inside the lighter so that the plasma tube 2 and the plasma head 1 can be assembled together without direct contact, thereby preventing the plasma tube 2 and the plasma head 1 from being conductive after power is applied.

[0040] In addition, the plasma head body 11 and the electrode lead-out portion 12 can be integrally formed or detachably connected. For example, a threaded receiving groove is provided at one end of the plasma head body 11 close to the electrode lead-out portion 12 so that the electrode lead-out portion 12 can be connected to the plasma head body 11 via threads.

[0041] It is understandable that the point where arcing occurs between the plasma head 1 and the plasma tube 2 is not fixed, and arcing may occur at any point in the circumferential direction. In this embodiment, a plurality of guide channels 311 are provided on the side wall of the guide portion 31. The guide channels 311 extend from the outer wall of the guide portion 31 to the inner wall of the guide portion 31 and are evenly distributed circumferentially on the guide portion 31. The guide channels 311 include a first opening 312 on the outer wall of the guide portion 31 and a second opening 313 on the inner wall of the guide portion 31. The guide channels 311 also include an oblique columnar guide hole extending from the first opening 312 to the second opening 313. The projection of the first opening 312 on the inner wall of the guide portion 31 does not overlap with the second opening 313. The first opening 312 is circular, and the second opening 313 is teardrop-shaped.

[0042] A fan or other structure may be provided inside the lighter. The wind generated by the fan is blown in from the first opening 312, flows through the guide channel 311, and is blown out from the second opening 313. Since the guide channel 311 is in the shape of an oblique column, the wind is tilted relative to the vertical plane when it is blown out. After multiple winds converge inside the guide portion 31, they form a whirlwind and flow upward, driving the generated plasma to spiral upward inside the plasma tube 2, thereby preventing the voltage at the point of arc ignition from being too high, which would break down the plasma tube 2 or the plasma head 1 and shorten the service life of the lighter.

[0043] The present application also provides a lighter comprising any one of the above-mentioned plasma generating components.

[0044] Obviously, the embodiments described above are only some of the embodiments of the present application, rather than all of the embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned specific embodiments, or to make equivalent replacements for some of the technical features therein. Any equivalent structure made using the contents of the present application specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the present application.
