Description

Technical Field

[0001] This utility model relates to the field of ignition, specifically to a rotary lighter with multiple flames that can be switched. Background Technology

[0002] A lighter is a small fire-starting device. It is mainly used for starting a fire, smoking, and also for cooking and other purposes. The main components of a lighter are the ignition mechanism and the gas tank. When the ignition mechanism is activated, it emits a spark that is directed towards the gas compartment, igniting the gas.

[0003] Existing lighters offer a variety of flame patterns, such as open flame, direct flame, false flame, and flames of different colors. To achieve flame switching, most existing lighters employ multiple generators. For example, Chinese Utility Model Patent CN218119800U discloses a lighter with flame switching functionality, comprising a housing, a flame outlet on the housing, and generators. The generators are connected to a nozzle via gas pipes. At least two generators are provided, and at least two of them emit different flame patterns. At least a portion of the gas pipe connecting at least one generator to the nozzle is elastically deformable. An actuator is rotatably connected to the housing, and the housing has an opening for the actuator to pass through. The actuator includes an operating part located outside the housing and a squeezing part located inside the housing. A limiting part is provided inside the housing. The elastically deformable portion of one of the gas pipes connecting one generator to the nozzle is located between the squeezing part and the limiting part. By squeezing one of the gas pipes connecting one generator to the nozzle, the flame switching is achieved.

[0004] After prolonged use, this switching method may cause tracheal deformation, which may render it unable to reset and thus prevent it from achieving the switching effect again. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: A rotary multi-flame switchable lighter, comprising: The grip is configured to be held and operated, and has a space for accommodating an ignition assembly, which includes a gas chamber and a piezoelectric element. The middle frame is fixedly installed at the upper end of the grip, and at least one mounting beam is provided on its inner side.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] Please see Figure 1 This utility model discloses a rotary multi-flame switchable lighter, which includes a grip and a rotating frame disposed on its upper end. The surface of the rotating frame is provided with several anti-slip textures, which allow the user to rotate the rotating frame by contacting the anti-slip textures, thereby switching the flame mode. The rotating frame is covered by a cover, leaving only the anti-slip textures that can be operated, which protects the flame outlet and improves the overall aesthetics. The cover has a hole whose size is adapted to the flame outlet. After the rotating frame rotates, the flame outlets will correspond to the hole in sequence.

[0031] like Figure 2 As shown, the grip 100 is configured to be gripped and operated. It includes a housing 110, the interior of which is hollow to form a space for accommodating an ignition assembly. The ignition assembly includes a gas box 120 and a piezoelectric element 140. The gas box is entirely disposed inside the housing and serves as the main body of the grip.

[0032] like Figure 5 and Figure 6 As shown, the middle frame 300 is fixedly installed on the upper end of the grip part 100, and at least one mounting beam 330 is provided on its inner side. The mounting beam 330 is provided with an air outlet 310, which is connected to the air outlet valve 130 of the air box 120. A metal conductor 320 electrically connected to the piezoelectric 140 is provided on either side of the mounting beam 330.

[0033] The rotating frame 200 is rotatably mounted on the upper side of the middle frame 300, and the rotating frame 200 is provided with a number of circumferentially distributed flame outlets, and each flame outlet is provided with a flame generating head 240. An electrode 250 for igniting the gas at the flame generating head 240 is provided on one side of any flame generating head 240.

[0034] In this embodiment, there are three flame outlets, which are distributed in an equilateral triangle on the upper surface of the rotating frame. The mounting beam is set in a non-central position of the middle frame, so that the gas nozzle is on the projection of the shape formed by the flame outlets. Thus, when rotating, the flame outlets can be set to correspond to the gas nozzle.

[0035] Each flame generator head 240 can be driven by the rotating frame 200 to align with the air outlet 310 respectively, and when the flame generator head 240 is aligned with the air outlet 310, the electrode 250 corresponding to the flame generator head 240 is in contact with the metal conductor 320.

[0036] A spring is provided between the metal conductor 320 and the middle frame to serve as a gear position. Therefore, three metal conductors are provided, each corresponding to one of the three flame outlets. Only one metal conductor is electrically connected to the piezoelectric element in the grip, while the other two are used only as gear position indicators.

[0037] When the rotating frame is rotated, after it has rotated to a certain angle, when the corresponding flame generator head and the gas outlet are on the same axis, the electrode corresponding to the flame generator head is just in contact with the metal conductor. At this time, ignition can be achieved by pressing the operation switch.

[0038] The flame can be any of the following: open flame, direct flame, flame of different colors, or artificial flame. At least three flame types can be formed by combination, and in other embodiments, there can be two or more. The flame can be switched by rotation.

[0039] like Figure 3 and Figure 4 and Figure 8 As shown, the rotating frame 200 includes: The support frame 210 has a mounting groove 211 on one side; A rotating cover 220 is disposed at the bottom of the support frame 210, and forms a space between the cover 220 and the support frame 210 to accommodate the flame generator head 240; The ceramic cup 230 is fixedly installed in the mounting groove 211.

[0040] The support frame is fixedly connected to the center of the rotating shaft by screws, and is also firmly connected to the intermediate stage by the cover, and can rotate relative to it within the cover.

[0041] The flame generator head passes through the support frame and is positioned within the space between the rotating cover and the support frame. Simultaneously, the electrode passes through the support frame and the ceramic cup in sequence, approaching the gas outlet of the flame generator head. The upper end of the electrode is bent, which allows for better ignition of the gas at the flame generator head.

[0042] The ceramic cup 230 is provided with a replaceable metal plate 260, which has three holes. Any one of the holes extends inward to form a tooth. Through the design of teeth made of different materials, it can present different colors when burned by flame.

[0043] Different colors of flame can be changed by replacing the metal plate.

[0044] like Figure 7 As shown, the bottom of the rotating cover 220 is provided with an annular groove 221, and the inner side of the annular groove 221 is provided with through holes 223 for the electrode 250 to pass through. A wiring groove 222 is provided between each through hole 223 and the annular groove 221. One end of the metal conductor 320 is configured as a sphere. The metal conductor moves along the annular groove, and when it reaches the point where it connects with the wiring groove, the depth is greater, thus providing a tactile feedback and indicating the gear position.

[0045] In addition, the spring between the metal conductor and the central frame is not shown in the figure. The spring is used to enable the metal conductor to make better contact with the electrode.

[0046] The bottom of the electrode is bent and extends along the wiring groove to the annular groove, thereby enabling the metal conductor to be electrically connected to the electrode, so that the electrode can ignite the gas at the flame generator head.

[0047] like Figure 9 As shown, an operation switch 400 for triggering the piezoelectric element 140 is provided on any side of the grip portion 100. In this embodiment, a button with one end hinged is used, while in other embodiments, a vertically arranged push button or a horizontally arranged push button can also be used. The function of the operation switch is to press the piezoelectric element when force is applied.

[0048] like Figure 12 As shown, the operation switch 400 is a button, one end of which is hinged to the air box 120. It can be moved into the gripping part under force. At the same time, a first trigger 410 and a second trigger 420 are provided on the side facing the gripping part. The first trigger 410 and the second trigger 420 are arranged along the length direction of the button.

[0049] The second trigger is used to press the rocker arm, which opens the air valve.

[0050] The gripping part 100 is provided with a rotatable linkage 500. The linkage 500 has a pressing end 510 mounted on the piezoelectric element 140 and a trigger end 520 that is connected to the first trigger 410 on one side.

[0051] The gas box is equipped with a bracket, and the linkage is rotatably mounted on the bracket. When its trigger end 520 is subjected to an inward force from the first trigger, the linkage rotates relative to the trigger and presses the electronic button.

[0052] like Figure 10 and Figure 11 As shown, a locking part 530 is provided on the other side of the linkage 500, and a rotatable dial 600 is provided inside the grip part 100. The dial 600 is partially exposed on the surface of the grip part, and a locking part 620 is provided coaxially with the dial 600. The locking part 620 can be moved to the rotation path of the linkage 500 under the action of external force.

[0053] By turning the dial, the locking element is positioned at the upper end of the locking part, thereby restricting the rotation of the linkage element under force.

[0054] The dial includes a shaft, an air box with a notch at one end, and a slot at the bottom for fixing the shaft. The shaft of the dial can rotate relative to the slot. At the same time, a gear shift member 610 is coaxially provided at the bottom of the gear shift member 610. The bottom of the gear shift member 610 has at least two gear shift slots. The air box 120 has a gear shift indicator 150 corresponding to the gear shift slot. The gear shift indicator is set in a hole at the bottom of the notch, and a spring is also provided at its bottom, so as to indicate the locked and unlocked state when it cooperates with the gear shift member.

[0055] Limiting elements are provided on both sides of the notch groove to limit the maximum rotation angle of the dial.

[0056] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
