Description

Technical Field

[0001] This utility model relates to the field of smoking accessories, specifically to a lighter cover and a lighter. Background Technology

[0002] A lighter is a common ignition device, also known as a cigarette lighter. Traditional gas-fired cigarette lighters are classified according to their ignition method, mainly including electronic ignition, piezoelectric ceramic (also known as piezoelectronic) ignition, and friction ignition with flint. Most conventional lighters have a lighter cover to cover and protect the ignition component or ignition port. The lighter cover is usually a flip-top type. For example, a kerosene lighter disclosed in Chinese patent CN216924419U has a lighter cover that is directly connected by a hinge, and the lighter cover is opened or closed manually. This type of lighter cover is the most common.

[0003] To ensure the reliability of the lighter cap's closure, some lighters use a snap-fit ​​connection. For example, Chinese patent CN220338499U discloses a self-locking automatic kerosene lighter, which uses a sliding locking element to lock the flame cap and prevent accidental opening. However, this structure is relatively complex and requires modifications to both the casing and the flame cap. Utility Model Content

[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 this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or a connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figure 1 As shown, this utility model discloses a lighter cover, which is mainly used to protect the flame outlet and can also protect the ignition component, i.e., cover both. The lighter involved in this embodiment is a kerosene lighter, so it needs to cover the cotton wick at the flame outlet to prevent kerosene from leaking from the flame outlet. At the same time, if it needs to protect the ignition component, the protective cavity of the ignition component and the protective cavity of the flame outlet need to be set independently to avoid kerosene at the flame outlet contaminating the ignition component. In this embodiment, the ignition component is a grinding wheel and a flint, which use the friction between the two to ignite the cotton wick.

[0032] The lighter cover includes a hinge seat 210 mounted on the body 200 and a cover body 100 rotatably mounted relative to the hinge seat. The cover body is rotatably engaged with the hinge seat via a pivot, which can move relative to the thickness of the body, such as... Figure 4As shown in the x-direction, this allows the cover to move closer to or further away from the hinge seat. Utilizing this feature, a limiting structure is set at the connection point between the two to ensure that when they are close together, the cover is restricted and covers the flame outlet. When the cover is forced away from the hinge seat, the restriction is lifted, and the cover can be opened. The opening method can be automatic opening using a second elastic element or manual opening, preferably automatic opening.

[0033] A hinge seat 210 is provided on the body 200, and the hinge seat 210 is provided with a hinge hole 230. The body includes a shell and a frame, wherein the frame and the shell cooperate to form a cavity, and a fuel tank is provided in the cavity. The fuel tank is connected to the fire outlet. In a preferred embodiment, the hinge hole 230 is integrally formed on the frame.

[0034] The cover 100 has a rotating part at one end, and the rotating part is provided with a rotating shaft 110 extending along the thickness direction of the lighter body. The rotating shaft 110 is rotatably disposed in the hinge hole 230. The rotating shaft 110 is inserted into the hinge hole and can rotate relative to it. At the same time, the rotating shaft 110 can also slide axially relative to the hinge hole. If the rotating shaft is a split structure, it is preferable to provide a limiting member on one side of the rotating shaft, located on the side where the cover and the hinge seat cooperate, thereby limiting the insertion position of the rotating shaft. At the same time, it can drive the cover to move synchronously when it is moved by force.

[0035] like Figure 3 As shown, when the lid is closed, the limiting block is inserted into the limiting groove, as... Figure 4 As shown, when the rotating shaft is subjected to force, the cover moves along the x-direction, causing the limiting block to disengage from the limiting groove.

[0036] The hinge seat 210 is provided with a limiting groove 220 on the side near the cover 100, and a limiting block 150 is provided on the side of the cover 100 to form a limiting engagement with the limiting groove 220.

[0037] One end of the rotating shaft 110 is provided with a force-receiving part, and a first elastic element 130 is provided between the force-receiving part and the hinge seat to drive the cover 100 to move towards the hinge seat 210. The first elastic element 130 is a spring, sleeved on the outside of the rotating shaft, and not between the hinge seat and the force-receiving part. When the force-receiving part is subjected to external force, it drives the cover 100 to move along the thickness direction of the body and releases the limiting block 150 from the limiting groove 220. The design of the first elastic element allows the cover to be reset under the action of the first elastic element after it is closed and the limiting block is aligned with the limiting groove. The operation is relatively simple. When the cover is pressed down, it will move relative to the hinge seat under the action of the first elastic element to complete the limiting of both.

[0038] like Figure 6As shown, the limiting grooves are distributed circumferentially around the hinge hole, and can be arc-shaped. The limiting block matches the limiting groove, and the limiting block is inserted into the limiting groove to form a limiting fit, preventing the cover from rotating relative to each other. When the rotating shaft is subjected to force and drives the cover to move outward, the limiting block disengages from the limiting groove, and the cover can be opened relative to each other under the action of external force.

[0039] A second elastic element, such as a torsion spring, is provided between the cover 100 and the body 200 to drive the cover 100 to rotate relative to the body 200. Figure 8 As shown, it is sleeved on the rotating shaft, with one end in contact with the cover and the other end inserted into the mating groove 250 on the machine body. Through the design of the second elastic element 600, it can rotate and open synchronously when the cover is released from the limit, that is, the cover opens automatically.

[0040] like Figure 5 As shown, the other end of the cover 100 is provided with a cover 170, which is connected to the rotating part via a connecting rod 180. Using a connecting rod 180 to connect the cover and the rotating part makes the cover more unique and improves the aesthetics of the lighter. In this application, the projected area of ​​the cover is larger than the area of ​​the flame outlet, thus allowing the cover to move relative to the flame outlet without affecting it.

[0041] like Figure 7 As shown, the rotating shaft 110 is a columnar structure with threaded grooves at both ends that mate with bolts. The rotating shaft passes through the cover and the hinge seat, and its two ends are fixedly connected to bolts to achieve the connection of the three. The split design makes installation more convenient, and the bolts enhance the metallic texture.

[0042] A button 120 is fixedly provided at the end of the rotating shaft 110 passing through the hinge hole 230. A first elastic element 130 is provided between the button 120 and the hinge seat 210. That is, in this embodiment, the button is used as the force-bearing part, and it is directly fixed to the rotating shaft by bolts. At the same time, a receiving groove 140 for accommodating the button 120 is formed on the other side of the hinge seat 210. The button is stored in the receiving groove, and there is a certain amount of travel between the bottom of the button and the bottom of the receiving groove, so that the button can move relative to the groove. At the same time, the button is reset by the first elastic element, that is, the spring.

[0043] The rotating shaft 110 is provided with a limiting rib 111 around its circumference, and the limiting rib 111 is located between the cover 100 and the hinge seat 210. The cover 100 is provided with a groove 160 on the side near the hinge seat 210, and the limiting rib 111 is embedded in the groove 160. The limiting rib not only limits the maximum position of the rotating shaft insertion, but also can be driven by force to move the cover.

[0044] The cover 100 and the side that contacts the hinge seat 210 are provided with reinforcing ribs 190 to reduce the friction surface.

[0045] like Figure 1 As shown, a lighter includes a body 200, an ignition assembly 400 and a flame outlet 300 on the upper surface of the body 200, and a lighter cover on the upper surface of the body 200. The lighter cover has a first position (e.g., covering the ignition assembly 400 and the flame outlet 300) that covers the ignition assembly 400 and the flame outlet 300. Figure 1 (as shown) and rotate to expose the second position of the ignition assembly 400 and the flame outlet 300 (as shown). Figure 2 (As shown).

[0046] like Figure 2 As shown, the ignition assembly in this embodiment is a grinding wheel ignition assembly, which is arranged sequentially with the ignition port along the thickness direction of the machine body. In order to better rotate the grinding wheel, an auxiliary wheel 500 is provided on one side of the grinding wheel. The grinding wheel is rotated synchronously by rotating the auxiliary wheel, and the diameter of the auxiliary wheel is set to be larger than the diameter of the grinding wheel.

[0047] 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.
