Description

Technical Field

[0001] The utility model particularly relates to a lighter with adjustable gas output. Background Art

[0002] Existing lighters, such as gas lighters, generally use a seesaw to open the air outlet valve. Conventional lighters all use a push-type opening method. For example, Chinese patent CN201875739U discloses a lighter, which discloses a rotating wheel provided on the housing. The air outlet valve is opened by rotating the rotating wheel, and the rotating wheel can be used to maintain the ignition state. However, it is impossible to adjust the air output volume. Moreover, in existing lighters using a rotary opening method, the rotating wheel can basically only be used to open and close the air outlet valve. If the air output volume is to be adjusted, a new adjustment structure needs to be set to adjust the air output volume. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] like Figure 1 and Figure 2 As shown, the utility model discloses a lighter with adjustable gas output, which includes a cylindrical shell 100, an air box 300, an ignition mechanism and an air outlet assembly. The ignition mechanism is arranged at the upper end of the cylindrical shell 100, and the ignition mechanism includes an ignition seat 500 and an ignition member 400. The air outlet assembly includes an air outlet valve 600 arranged at the air box 300 and an air opening element matched with the air outlet valve 600. Preferably, the air box is directly used as the lower part of the lighter, and the cylindrical shell is used as the upper part, and the two are fixed to form a whole, or they can also be The gas box is arranged inside the cylindrical shell and is configured according to needs. This application takes the two separate settings as an example, that is, the cylindrical shell is mainly used to support the ignition mechanism, which is fixed to the gas box as a whole by screws. At the same time, an arc groove is provided at the connection between the two for the rotation of the opening element, so that the gas opening element can rotate relative to each other. At the same time, the gas opening element in this application is a rotating wheel, and the outer ring of the rotating wheel is placed on the outside of the cylindrical shell and can rotate relative to each other. At the same time, the outer ring can be a non-complete circle, that is, it can be a structure with a certain arc length, which can be rotated relative to the cylindrical shell.

[0029] The outlet valve 600 is provided with a wheel 700 for adjusting the outlet volume. The outlet valve adopts a conventional outlet valve, and a wheel is provided on the outer side of the gear for adjusting the outlet volume. The wheel is provided with teeth meshing with the wheel, so that the wheel rotates to drive the outlet volume of the outlet valve to adjust.

[0030] One end of the rotating wheel 700 extends outward to form a linkage portion 710, which is used to cooperate with the air opening element to drive the same to rotate relative to each other, thereby adjusting the air output.

[0031] like Figure 3 and Figure 4 As shown, the air opening element is a rotating wheel 200 that forms a circumferential rotational fit with the cylindrical housing, and the rotating wheel 200 includes:

[0032] The outer ring 220 is sleeved on the outside of the cylindrical housing 100 and forms a circumferential rotational fit with the cylindrical housing 100. In this embodiment, a complete circular structure is adopted, and the entire ring is sleeved on the outside of the cylindrical housing, which is more beautiful and elegant. In some embodiments, it can also adopt a non-complete circular structure, that is, similar to an arc-shaped piece, which fits on the surface of the cylindrical housing and can also rotate relative to it;

[0033] The inner ring 210 is a circular ring structure. The upper end surface of the inner ring 210 is linked to the outlet valve 600, and the lower end surface forms a cam with the upper end surface of the air box 300. That is, the inner ring 210 can be rotated to achieve a change in height, thereby opening or closing the outlet valve;

[0034] The connecting arm 230 connects the outer ring 220 and the inner ring 210. When the outer ring 220 rotates circumferentially, the inner ring 210 is axially displaced and the outlet valve 600 is opened. The connecting arm directly connects the two and enables the outer ring to drive the inner ring to rotate, thereby causing the cam to cooperate with each other to change in height.

[0035] At least two limiting protrusions 221 are provided on the inner wall of the outer ring 220, and the arc length between the two is adapted to the rotation angle of the inner ring 210 driving the outlet valve from closed to open, and one end of the linkage part is placed between the two limiting protrusions 221, and when the inner ring 210 rotates to the position where the outlet valve is opened, one of the limiting protrusions 221 can drive the rotating wheel 200 to rotate synchronously.

[0036] The design of the two limiting protrusions is used to drive the rotating wheel to rotate clockwise or counterclockwise, thereby realizing the adjustment of the size of the air outlet, from large to small or from small to large, and the distance between the two limiting protrusions just meets the stroke amount of the rotating wheel to drive the air outlet valve to open and close, that is, when the rotating wheel is in the closed position and moves to the open position, the limiting protrusion will not drive the rotating wheel to rotate. When and only when it is in the open state, the limiting protrusion can drive the rotating wheel to rotate together with the rotating wheel, thereby adjusting the firepower in the fire state.

[0037] like Figure 3 As shown, the upper end surface of the air box 300 is provided with an arc-shaped wall 310, and the air outlet valve 600 is arranged at the center of the arc-shaped wall 310. A notch is provided on one side of the arc-shaped wall. The size of the notch just meets the rotation angle of the connecting arm, so that it can realize the sequential switching of the set gears.

[0038] One end of the inner ring 210 protrudes outward to form a positioning protrusion 211, and a plurality of positioning grooves 320 adapted to the positioning protrusion 211 are provided on the inner side of the arc-shaped wall 310. The plurality of positioning grooves are respectively used for prompting different gears, such as the off gear, the on gear, the fire power 1 gear, the fire power 2 gear, etc., so that when rotating, the hand feel is better and it can be more clearly understood whether it is rotated into place.

[0039] The inner ring 210 is provided with a through hole 214 on one side close to the positioning protrusion 211 for making the positioning protrusion 211 deformable. The through hole 214 is provided so that the inner side of the positioning protrusion is relatively suspended. The toughness of the material at the connection is utilized to give it a certain deformation ability, thereby better performing gear switching.

[0040] The upper end surface of the inner ring 210 is provided with a U-shaped snap ring 800 for driving the outlet valve 600 to move. The U-shaped snap ring can be driven by the inner ring to move along the axial direction to open or close the outlet valve.

[0041] The lower end surface of the inner ring 210 extends downward to form a first boss 212, and a first transition surface 213 is provided at the front end of the first boss 212 in the rotation direction. The upper end surface of the air box 300 is provided with a second boss 330 adapted to the first boss 212, and the second boss 330 is provided with a second transition surface 340 facing the first boss 212. The two cooperate with each other to realize the lifting change during the rotation process, so that the inner ring drives the U-shaped retaining ring to move relative axially to open or close the outlet valve.

[0042] There are two first bosses 212 , which are respectively disposed on both sides of the inner ring 210 , to achieve a balanced state and make the movement smoother.

[0043] There are two second bosses 330 , and a gap is provided between the two second bosses 330 for the linkage portion 710 of the rotating wheel 700 to rotate, that is, the rotating wheel can be limited by the maximum rotation angle, thereby ensuring the reliability of the adjustment.

[0044] like Figure 6 As shown, when in the closed state, one side of the linkage part of the rotating wheel contacts the second boss, and the other side contacts the limiting protrusion that is not under the connecting arm. At this time, the rotating wheel rotates relatively, and its connecting arm is still at a certain distance from the linkage part. This distance can meet the stroke required for the outlet valve to move from closing to opening.

[0045] picture Figure 7 and Figure 8 As shown, when it is rotated to the open position, the connecting arm rotates to the top of the linkage part, and the limiting protrusion on the lower side of the connecting arm contacts the linkage part, and drives the wheel to rotate synchronously with the rotating wheel to achieve the adjustment of the air output.

[0046] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the scope of protection of the present invention.
