Description

Technical Field

[0001] This application relates to the field of lighter technology, specifically to a safety lighter. Background Technology

[0002] Igniters use the generated electric arc or flame for ignition, thus posing a certain degree of danger. As everyday items, they need to be carried at all times. For devices using flint, a cover is usually installed to prevent flint powder from spreading. To ensure reliable closing and quick opening of the cover, one structure uses a flexible drive mechanism. The elastic force of this mechanism, misaligned with the hinge shaft, creates a driving force that allows the cover to close reliably. Another structure uses a spring-loaded spring at the hinge of the cover, with a locking mechanism on the body to lock the cover closed. However, during transport, the cover can still be accidentally flipped open by external force or the locking mechanism button can be accidentally triggered, leading to danger and thus reducing the safety of the igniter. Utility Model Content

[0003] In view of this, this application provides a safe lighter to solve the technical problem of low safety.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A safety lighter includes a body and a cover hinged to the body. A first elastic element is provided between the cover and the body to enable the cover to open automatically. A locking arm is hinged to the body and has a locking groove that can engage with the locking hook of the cover. A second elastic element is provided between the locking arm and the body to enable the locking arm to return to its original position automatically. The body / cover is also provided with a locking structure that prevents the locking arm from rotating and thus separates the locking arm from the cover.

[0006] Furthermore, the locking structure includes a slider that is slidably mounted on the machine body and an elastic structure acting on the slider, which prevents the locking arm from rotating.

[0007] Furthermore, the slider is located below the locking arm, and when in the locked state, the slider is inserted into the inside of the locking arm.

[0008] Furthermore, the elastic structure includes elastically floating balls, and the inner side of the slider has a recess that can cooperate with the balls.

[0009] Furthermore, a driven wheel coaxial with the steel wheel is installed on the fuselage, and a drive fork on the head cover can rotate the driven wheel to drive the steel wheel to rotate and ignite the fuselage when the head cover rotates.

[0010] Furthermore, the passive wheel is shaped like a multi-angled dart.

[0011] Furthermore, the drive fork is hinged to the head cover, and the drive fork is provided with a limiting platform that can abut against the head cover to lift the drive fork in linkage.

[0012] Furthermore, the fuselage is equipped with a support elastic structure that can resist the drive fork. When the cover is closed, the support elastic structure pushes the drive fork upward to resist the cover.

[0013] As can be seen from the above technical solution, the advantages of this utility model are:

[0014] 1. This application includes a locking mechanism for locking the locking arm, which makes the locking arm less likely to be triggered when locked, thereby improving security.

[0015] 2. In this application, a slider is used to lock the locking arm. Since the operating surface of the slider can be flush with or slightly protruding from the side of the machine body, the probability of being accidentally triggered is reduced, and the safety of use is further improved.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0022] refer to Figures 1 to 3 ,like Figure 1 and Figure 2As shown, this embodiment provides a safety lighter, including a body 1 and a cover 2 hinged to the body 1. A first elastic element 30 is provided between the cover 2 and the body 1 to enable the cover 2 to open automatically. A locking arm 7 is hinged to the body 1. The locking arm 7 has a locking groove that can cooperate with the locking hook of the cover 2. A second elastic element 20 is provided between the locking arm 7 and the body 1 to enable the locking arm 7 to return to its original position automatically. The body 1 / cover 2 is also provided with a locking structure that can prevent the locking arm 7 from rotating and thus separate the locking arm 7 from the cover 2.

[0023] When the locking arm 7 is locked with the cover 2, the locking hook of the cover 2 is located inside the locking arm 7. The locking structure can be a sliding or rotating part set on the cover 2. The sliding or rotating part can be automatically reset by using an elastic element to make the locking structure abut against the outer end of the locking arm 7, so that the locking arm 7 is limited between the locking hook of the cover 2 and the locking structure to restrict the rotation of the locking arm 7. Alternatively, the position of the sliding or rotating part can be locked by using an elastic element. The locking structure and the locking arm 7 form a double lock, thereby improving the safety of the lighter.

[0024] In this application, the first elastic element 30 and the second elastic element 20 are preferably torsion springs, which makes the structure compact. Moreover, the torsion springs are standard parts, and production costs can be reduced by purchasing them externally.

[0025] Preferably, in this application, the locking structure is disposed on the body 1.

[0026] The locking structure can be a rotating component. The rotating component can automatically reset using a torsion spring. The rotating component has a receiving cavity that can hold the operating part of the locking arm 7. The locking arm 7 is locked by the holding of the rotating component. When it is necessary to unlock, first turn the rotating component to release the locking arm 7, and then press the locking arm 7 to release the head cover 2. Ignition is performed during the automatic opening of the head cover 2.

[0027] Preferably, in this application, the locking structure includes a slider 8 slidably disposed on the body 1 and an elastic structure acting on the slider 8, thereby preventing the locking arm 7 from rotating.

[0028] Specifically, the slider 8 may be provided with a slot into which the operating part of the locking arm 7 can be inserted, or the slider 8 may block one side of the locking arm 7 to restrict the rotation of the locking arm 7. When it is necessary to block one side of the locking arm 7 to lock the position of the locking arm 7, the slider 8 may be positioned on the inside or outside of the locking arm 7 according to the operating direction of the locking arm 7 to lock the position of the locking arm 7.

[0029] Preferably, in this application, the locking arm 7 is located outside the locking hook of the head cover 2, and the driving part of the locking arm 7 is located below the hinge axis of the locking arm 7. The head cover 2 can only be unlocked by pressing the driving part of the locking arm 7. The slider 8 is located below the locking arm 7. When in the locked state, the slider 8 is inserted into the inside of the locking arm 7 to prevent the locking arm 7 from rotating, so that the upper end of the slider 8 is hidden, making the slider 8 less likely to be accidentally driven. At the same time, the operating part of the locking arm 7 can be tilted outward for easy operation.

[0030] The elastic structure acting on the slider 8 can be a spring set between the slider 8 and the body 1, which pushes the slider 8 to move and reset.

[0031] In this embodiment, the elastic structure includes a ball bearing 9 that is elastically floating on the body 1, and a recess 81 on the inner side of the slider 8 that can engage with the ball bearing 9. The slider 8 is locked in position by the engagement of the corresponding recess 81 with the ball bearing 9, so that the slider 8 can always be kept in the unlocked position, and the locking arm 7 is kept in the released state, which facilitates the automatic locking of the head cover 2 by the locking arm 7, so that the setting of the slider 8 does not affect the ease of locking the head cover 2.

[0032] Specifically, the pressure cap nut threaded onto the body 1 restricts the ball bearing 9 and the top pressure spring 10 abutting against the ball bearing 9 within the mounting hole of the body 1, making it easy to install and replace the ball bearing 9 and the top pressure spring 10. The slider 8 has a C-shaped cross-section and is slidably connected to the guide rail on the body 1. The ball bearing 9 is set on the guide rail, and the outer side of the slider 8 is flush with the outer side of the body 1, further reducing the probability of the slider 8 being accidentally triggered and further improving the safety of use.

[0033] In this application, a passive wheel 5 coaxial with the steel wheel 3 is installed on the body 1. The drive fork 6 set on the head cover 2 can rotate the steel wheel 3 by turning the passive wheel 5 when the head cover 2 rotates. This drives the steel wheel 3 to rotate and work in conjunction with the flint assembly 4 set in the body 1 to ignite the fuse.

[0034] Specifically, the passive wheel 5 uses a one-way structure to connect with the steel wheel 3, and when the drive fork 6 moves in the opposite direction, it can drive the passive wheel 5 to rotate independently.

[0035] To improve the driving reliability of the driven wheel 5, the driven wheel 5 is shaped like a multi-angled dart. The drive fork 6 can drive the steel wheel 3 to rotate by engaging with any of the protruding angles, ensuring reliable ignition and adding to the fun of operation with its unique design.

[0036] To ensure operational safety, i.e., ignition does not occur until the fire extinguishing cover 2 is separated from the nozzle, the drive fork 6 is hinged to the cover 2, and the drive fork 6 is provided with a limiting platform 61 that can abut against the cover 2, causing the drive fork 6 to lift in conjunction. When the cover 2 is open, initially, the drive fork 6 does not rotate under the influence of gravity. After the cover 2 rotates a certain angle and abuts against the limiting platform 61, it drives the drive fork 6 to rotate together to ignite. When the cover 2 is closed, initially, the cover 2 and the drive fork 6 are linked. After the cover 2 rotates a certain angle, the drive fork 6 is pressed down a certain angle and abuts against the body 1 to prevent the drive fork 6 from continuing to rotate. The cover 2 continues to rotate until it is closed.

[0037] To prevent the drive fork 6 from swinging arbitrarily when the head cover 2 is closed, the machine body 1 is provided with a support elastic structure 11 that can resist the drive fork 6. When the head cover 2 is closed, the support elastic structure 11 pushes the drive fork 6 up to resist the head cover 2. By using the support elastic structure 11, the machining and installation accuracy of the drive fork 6 can be reduced.

[0038] Preferably, in this application, the supporting elastic structure 11 is an elastic plate with one end connected to the body 1 and the other end raised, and the driving fork 6 can abut against the raised end of the elastic plate.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
