Description

Technical Field

[0001] This invention specifically relates to a lighter that automatically scrapes magnesium strips. Background Technology

[0002] Lighters are everyday products used for ignition, such as lighting cigarettes. Most lighters use piezoelectric or a combination of a flint and a grinding wheel for ignition. Magnesium bars, on the other hand, require scraping to ignite. Therefore, magnesium bars are mostly used in fire starters, where a scraper is used to scrape the magnesium bar and use the principle of friction to ignite flammable materials. Magnesium bars are generally not used for igniting lighters. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a lighter that automatically scrapes magnesium strips.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An automatic magnesium strip scraper lighter includes a housing, a fuel tank disposed inside the housing, and a bracket disposed on the upper part of the fuel tank. A flame outlet is provided on one side of the bracket, a magnesium strip is disposed above the flame outlet, and a reciprocating assembly is disposed below the magnesium strip. A scraper is provided at the front end of the reciprocating assembly and contacts the magnesium strip. An elastic element is provided between the rear end of the reciprocating assembly and the bracket. A release element is hinged inside the reciprocating assembly, and a spring is provided on the lower side of the release element. A sliding cover is provided above the flame outlet, which is horizontally slidable with the housing. A linkage element is provided at the bottom of the sliding cover, positioned between the scraper and the release element and abutting against the release element. An operating element is provided on the housing to drive the sliding cover to slide. The sliding cover has a first state in which it abuts against the release element, causing the reciprocating assembly to move synchronously and compress the elastic element, and a second state in which it releases the contact with the release element. Under the reset action of the elastic element, the reciprocating assembly moves in the opposite direction, causing the scraper to rub against the magnesium strip.

[0006] The reciprocating assembly includes a guide seat, and the front end of the guide seat is provided with a scraper mounting groove and a release component fixing groove in sequence. One end of the release component is hinged to the release component fixing groove, and a spring piece is provided between the lower side of the release component and the bottom of the fixing groove.

[0007] The rear end of the guide seat is provided with a guide rod, and the bracket is provided with a guide hole that matches the guide rod.

[0008] The bracket is provided with magnesium strip fixing holes, and the magnesium strip can be detachably passed through the magnesium strip fixing holes.

[0009] Fasteners are provided in the vertical fixing holes of the magnesium strip.

[0010] The bracket is symmetrically provided with two limiting plates, and a sliding groove is formed between the two limiting plates for the sliding cover to slide.

[0011] The sliding cover is provided with push rods at one or both ends, and the housing is provided with guide grooves that are adapted to the push rods. The push rods pass through the guide grooves and are linked with the operating components.

[0012] The operating component is a dial wheel, which is rotatably mounted on one or both sides of the housing. The dial wheel is provided with a linkage groove that is linked to the sliding cover.

[0013] The inner side of the dial extends into the housing to form a lever that works in conjunction with the rocker arm.

[0014] The dial wheel is provided with an arc-shaped groove, and a tension spring for resetting the dial wheel is provided in the arc-shaped groove.

[0015] The beneficial effects of this invention are as follows: the sliding cover is moved by the operating component, and the reciprocating assembly is moved when the sliding cover is opened by the cooperation of the linkage component and the release component. When the sliding cover reaches a certain position, the linkage component and the release component are disengaged, so that the reciprocating assembly moves forward under the action of the elastic component, thereby causing the scraper to rub against the magnesium strip, thereby realizing ignition. The whole process is fully automatic. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort 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 positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" 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 elements or the interaction between two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] As shown in the figure, an automatic magnesium strip scraper lighter includes a housing 1, a fuel tank 9 disposed inside the housing, and a bracket 12 disposed above the fuel tank. The fuel tank 9 has a vent valve 10, and a rocker arm 11 is provided at the vent valve for opening the vent valve. A flame outlet 5 is provided on one side of the bracket, and the vent valve is connected to the flame outlet via a conduit. A magnesium strip 6 is disposed above the flame outlet and is used in conjunction with a magnesium strip mounting component. A reciprocating assembly 8 is disposed below the magnesium strip. The front end of the reciprocating assembly has a scraper that contacts the magnesium strip, and an elastic joint is provided between the rear end of the reciprocating assembly and the bracket. The reciprocating assembly is hinged with a release member, and a spring is provided on the lower side of the release member. A sliding cover 4 is provided on the upper side of the fire outlet, which is configured to slide horizontally with the housing. A linkage member is provided at the bottom of the sliding cover. The linkage member is placed between the scraper and the release member and abuts against the release member. An operating member is provided on the housing to drive the sliding cover to slide. The sliding cover has a first state in which it abuts against the release member and drives the reciprocating assembly to move synchronously and compress the elastic member, and a second state in which it releases the abutment from the release member. The reciprocating assembly moves in the opposite direction under the reset action of the elastic member, causing the scraper to rub against the magnesium strip.

[0030] Its working principle is as follows:

[0031] By operating the actuator, the sliding cover slides backward. Since the sliding cover's linkage is counteracted by the release mechanism, the sliding cover and reciprocating assembly move as one, synchronously. The reciprocating assembly compresses the elastic element, but its movement distance is less than the sliding cover's. Therefore, after moving a certain distance together, the reciprocating assembly is restricted from further movement. The sliding cover continues to move, while the linkage continues to move backward, passing the release mechanism. Once past the release mechanism, the linkage between the sliding cover and the reciprocating assembly is released. Due to the restoring force of the elastic element, the reciprocating assembly moves forward, causing rapid friction between the scraper and the magnesium strip, generating a spark and achieving ignition. The sliding cover then moves forward, passing the release mechanism again to resume its counteracting engagement, thus meeting the requirements for the next ignition.

[0032] The reciprocating assembly includes a guide seat 17. The front end of the guide seat is provided with a scraper mounting groove 19 and a release member fixing groove 20 in sequence. One end of the release member is hinged to the release member fixing groove, and a spring piece 21 is provided between the lower side of the release member 16 and the bottom of the fixing groove. The spring piece is used to set the highest point of the release member slightly higher than the guide seat, so that it can abut against the linkage member 22. The scraper 15 and the scraper mounting groove are provided with a spring. The spring drives the scraper to press against the magnesium strip, so that the contact between the two is more reliable.

[0033] The release element has a recessed bottom, where a spring is embedded and its lateral movement is restricted.

[0034] The rear end of the guide seat is provided with a guide rod 18, and the bracket is provided with a guide hole 27 that is adapted to the guide rod. The guide rod is fitted with an elastic element, which is a spring. When the guide rod moves, it cooperates with the guide hole to ensure its direction of movement. At the same time, the design of the guide rod can make the moving distance of the reciprocating component less than the moving distance of the sliding cover, thereby enabling the linkage and release components to switch between two positions.

[0035] The bracket is provided with magnesium strip fixing holes 26, and the magnesium strip is detachably installed through the magnesium strip fixing holes.

[0036] The magnesium strip fixing hole is provided with a fastener 7, which is used to press the magnesium strip tightly against the scraper, making the contact between the two more compact, and also serving a fixing function.

[0037] The bracket is symmetrically provided with two limiting plates 25, and a sliding groove is formed between the two limiting plates to allow the sliding cover to slide, thereby restricting the direction of movement of the sliding cover.

[0038] The sliding cover is provided with push rods 24 at one or both ends, and the housing is provided with guide grooves 14 that are adapted to the push rods. The push rods pass through the guide grooves and are linked with the operating components. The guide grooves are elongated structures and will not interfere with their operation.

[0039] Meanwhile, the sliding cover has a through hole 23 for the magnesium strip to pass through, so that it will not interfere with the magnesium strip when the sliding cover slides. The sliding cover and the housing are provided with raised ribs to reduce the friction between them.

[0040] The operating component is a dial 2, which is rotatably mounted on one or both sides of the housing. The housing is provided with raised ribs to reduce the friction between the two. The dial is provided with a linkage groove 28 that is linked to the sliding cover. The linkage groove is a strip-shaped hole extending towards the center of rotation. When it rotates, the push rod can move in the strip-shaped hole, thereby driving the sliding cover to move.

[0041] The inner side of the dial extends into the housing to form a lever 29 that works in conjunction with the rocker arm, and can open the air valve while rotating.

[0042] The dial wheel is provided with an arc-shaped groove 30, and a tension spring for dial wheel reset is provided in the arc-shaped groove. One end of the tension spring cooperates with the groove wall of the arc-shaped groove, and the other end cooperates with the limiting post 13 on the housing. When the dial wheel is rotated, it will stretch the tension spring. Therefore, when released, it will reset under the action of the self-restoring force of the tension spring, thereby driving the sliding cover to reset.

[0043] 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.
