Description

Technical Field

[0001] This application relates to the field of lighter technology, specifically to a cap locking structure and a lighter having the cap locking structure. Background Technology

[0002] Currently, most commonly used flip-top lighters use an elastic force acting on the cap to keep it closed or open. When the cap is closed, it is easily flipped up by external force, which can easily cause accidental ignition. The stability of the cap's closed state directly affects the safety of carrying and using it. Therefore, various structures for locking the cap have emerged. However, existing cap locking structures usually combine an additional linkage structure with the locking structure, such as CN201920898310.8, CN200510094126.0, and 202323129350.1. These structures are relatively complex, and the additional linkage structure occupies a lot of space. They are not well-suited for lighters with horizontally positioned flint ignition components, such as CN201909335U. Utility Model Content

[0003] In view of this, this application provides a cap locking structure and a lighter having the cap locking structure to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this application provides the following technical solution: A head cover locking structure includes a flint holder latch on the flint holder of the flint ignition assembly and a head cover latch on the head cover. The flint holder latch and the head cover latch cooperate to work together. The flint holder is slidably set and the head cover is hinged. When the head cover needs to be opened, the flint rack is moved to make the flint rack latch and the head cover latch horizontally offset, thus releasing the head cover. When the head cover is closed, after the head cover latch moves to below the flint rack latch, the flint rack moves forward and resets under the action of external force, causing the flint rack latch to move directly above the head cover latch, thus locking the head cover.

[0005] Furthermore, once the head cover is released, it automatically opens under the action of elastic driving force.

[0006] Furthermore, an elastic force is applied to the end of the flint holder away from the flint wheel. The lighter body is equipped with a limiting structure to restrict the reset position of the flint holder. During the closing of the cover, the cover latch will abut against the flint holder latch and push the flint holder backward. After the cover latch passes over the flint holder latch and moves below it, the flint holder moves forward and resets under the action of the elastic force, causing the flint holder latch to move directly above the cover latch.

[0007] Furthermore, the limiting structure is a limiting strip hole set on the body, and the steel wheel axle of the ignition steel wheel slides in conjunction with the limiting strip hole.

[0008] Furthermore, the lower part of the head cover latch is provided with a guide ramp, and when the head cover latch comes into contact with the flint rack latch, the flint rack latch moves along the guide ramp.

[0009] Furthermore, a return spring that generates elastic force is provided between the flint frame and the fuselage.

[0010] Furthermore, the fuselage is equipped with a cap limit stop to restrict the opening range of the cap.

[0011] In view of the disclosed headgear locking structure, this application discloses another technical solution: A lighter including the above-described cap locking structure, the lighter body has an installation channel that slides with the flint holder, the body has a first cotton thread opening and a second cotton thread opening, the cap has a fire extinguishing cover that mates with the first cotton thread opening and a cotton thread screw that mates with the second cotton thread opening, when the cap is closed, one end of the ignition cotton thread passing through the cotton thread screw extends into the second cotton thread opening.

[0012] Furthermore, the flint ignition assembly also includes an adjustment screw connected to the flint holder, which is located on the outside of the body.

[0013] Furthermore, the head cover has a connecting channel with one end connected to the outside, the other end of the ignition cotton thread is located in the connecting channel, and the connecting channel is also filled with cotton. A sealing screw plug is installed on the outer port of the connecting channel.

[0014] Compared with the prior art, the beneficial effects of this application are: 1. In the headgear locking structure of this application, a movable flint holder is used as the locking execution structure and operation structure, and no other additional structures are required, making the headgear locking structure simple. 2. In the head cover locking structure of this application, the flint holder works in conjunction with the return spring. By moving the flint holder, the head cover is released, and the head cover automatically pops open. The mechanism locks at the instant the head cover closes, making operation convenient.

[0015] 3. The lighter of this application is equipped with dual ignition cotton wires, one of which is located on the head cap, so as to meet the ignition needs of pipes and other products that require the flame to be located on the side without affecting the flipping of the lighter; the other ignition cotton wire is located on the body of the lighter to meet normal ordinary ignition needs.

Detailed Implementation

[0025] 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.

[0026] Example 1 refer to Figures 1 to 7 ,like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, this embodiment provides a head cover locking structure, including a flint holder latch 211 disposed on the flint holder 21 of the flint striking assembly 2 and a head cover latch 35 disposed on the head cover 3. The flint holder latch 211 and the head cover latch 35 cooperate to work together. The flint holder 21 is slidably disposed, and the head cover 3 is hingedly mounted. When the head cover 3 needs to be opened, the flint holder 21 is driven to move backward, causing the flint holder latch 211 and the head cover latch 35 to be misaligned in the horizontal direction, and the head cover 3 is released. When the head cover 3 is closed, after the head cover latch 35 moves to below the flint holder latch 211, the flint holder 21 moves forward and resets under the action of external force, causing the flint holder latch 211 to move directly above the head cover latch 35, so that the head cover 3 enters the locked state.

[0027] To make it easy to open the cover 3, after the cover 3 is released, the cover 3 opens automatically under the action of elastic driving force, without the need for manual driving of the cover 3 to open.

[0028] Specifically, a torsion spring 4 is installed at the hinge shaft of the head cover 3, and the two ends of the torsion spring 4 are connected to the head cover 3 and the body 1 respectively.

[0029] In this application, the cover 3 can also be connected to the over-center elastic jacking mechanism. After the cover 3 is released, if the cover 3 is manually turned to open beyond a certain angle, the cover 3 will automatically open using the torque force applied to the hinge shaft by the over-center elastic jacking mechanism. When the cover 3 is closed, if the cover 3 is manually turned to close beyond a certain angle, the cover 3 will automatically close using the torque force applied to the hinge shaft by the over-center elastic jacking mechanism. The specific structure of the over-center elastic jacking mechanism can be referred to the automatic swing mechanism for the cover over-center in CN201320377110.0 and the elastic mechanism in CN 104832947A. The specific structure of the cover 3 can be adapted and adjusted according to the structure of the over-center elastic jacking mechanism.

[0030] In this embodiment, one configuration of the flint holder 21 is as follows: the flint holder 21 is slidably installed, and an elastic damping mechanism is provided on the side of the flint holder 21. The elastic damping mechanism can be a locking structure in which an elastic element and a ball cooperate. The flint holder 21 is provided with a groove that cooperates with the ball. The ball and the groove are used to prevent the flint holder 21 from sliding and moving at will. The elastic damping mechanism can also be a structure combining an abutment and an elastic element. The contact friction between the abutment and the flint holder 21 is used to prevent the flint holder 21 from sliding and moving at will.

[0031] like Figure 4As shown, in this preferred embodiment, an elastic force is applied to the end of the flint holder 21 furthest from the flint wheel 22. The lighter body 1 is provided with a limiting structure to restrict the flint holder 21's forward and return limit position. During the closing of the cover 3, the cover latch 35 abuts against the flint holder latch 211 and pushes the flint holder 21 backward, increasing the elastic force. After the cover latch 35 passes over the flint holder latch 211 and moves below it, the flint holder 21 returns to its original position under the action of the elastic force, causing the flint holder latch 211 to move directly above the cover latch 35, achieving automatic locking. Utilizing the characteristic of automatic reset by elastic force makes the cover locking structure more convenient to use, and the use of the limiting structure makes the flint holder 21 stable during the reset process.

[0032] Specifically, a return spring 5 that generates elastic force is provided between the flint frame 21 and the body 1, and the return spring 5 is sleeved on the flint frame 21. The flint frame 21 is provided with a limiting surface for the return spring 5 to abut against.

[0033] In this embodiment, the limiting structure is a limiting strip hole 12 provided on the body 1, and the steel wheel axle 23 of the flint wheel 22 slides in conjunction with the limiting strip hole 12. By using the limiting strip hole 12 for limiting, both ends can be limited, avoiding excessive compression of the return spring 5 and excessive reset of the flint frame 21.

[0034] In this application, the limiting structure can be a cam shaft mounted on the fuselage 1, and the flint holder 21 has a guide groove that mates with the cam shaft.

[0035] When the flint holder 21 is pushed back by elastic force, in order to facilitate the locking process of the head cover, the lower part of the head cover latch 35 is provided with a guide slope 351. When the head cover latch 35 abuts against the flint holder latch 211, the flint holder latch 211 will automatically retract during the movement along the guide slope 351, without the need for manual assistance to move the flint holder 21, thus making the locking process of the head cover convenient.

[0036] When the head cover 3 works in conjunction with the torsion spring 4, in order to limit the maximum opening angle of the head cover 3, the body 1 is provided with a head cover limiting block 13 to limit the opening range of the head cover 3.

[0037] In use, the flint holder 21 is moved against the elastic force by manually pressing the flint wheel 22, and the head cover 3 is released and opened automatically. After use, the head cover 3 is closed manually until it is completely closed. After the head cover 3 is closed, the flint holder 21 is automatically reset under the action of elastic force, thus locking the head cover 3.

[0038] Example 2 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, based on Embodiment 1, this application discloses a lighter including the above-described cover locking structure. The lighter body 1 has an installation channel 11 that slides with the flint holder 21. The body 1 has a first cotton thread opening 14 and a second cotton thread opening 15. The cover 3 has a fire extinguishing cover 31 that cooperates with the first cotton thread opening 14 and a cotton thread screw 32 that cooperates with the second cotton thread opening 15. When the cover 3 is closed, one end of the ignition cotton thread that passes through the cotton thread screw 32 extends into the second cotton thread opening 15. The second cotton thread opening 15 is connected to the fuel tank. When in use, after the cover 3 is closed, the second ignition cotton thread that passes through the cotton thread screw 32 can enter the body 1 through the second cotton thread opening 15. When the lighter is tilted or shaken, the second ignition cotton thread will come into contact with the fuel and absorb the fuel. After the cover 3 is opened, when the first ignition cotton thread located at the first cotton thread opening 14 is lit, the ignition end of the second ignition cotton thread after absorbing the fuel can be brought close to the ignition end of the first ignition cotton thread for ignition by rotating the cover 3. By adjusting the angle of the cover 3, the body 1 can meet the needs of side or diagonal ignition for pipes and other items without tilting. The first ignition cotton thread is used to meet the needs of normal ignition.

[0039] In this embodiment, the flint ignition assembly 2 also includes an adjusting screw 26 connected to the flint holder 21, which is located on the outside of the body 1. This facilitates the replacement of the flint 24 and the push spring 25 installed in the flint holder 21, and also facilitates the adjustment of the pushing force exerted by the push spring 25 on the flint 24.

[0040] To prevent excessive force on the steel wheel axle 23 when turning the adjusting screw 26, a slide rail is provided on the side of the flint frame 21, and a track groove that cooperates with the slide rail is provided in the installation channel 11.

[0041] like Figure 3 As shown, the head cover 3 has a connecting channel 33 with one end connected to the outside. The other end of the second ignition cotton wire is located in the connecting channel 33, and the connecting channel 33 is also filled with cotton. The fuel drawn in along the second ignition cotton wire can be stored in the cotton. The storage of fuel helps to extend the ignition time of the second ignition cotton wire. A sealing plug 34 is installed on the outer port of the connecting channel 33 to facilitate the installation and replacement of cotton.

[0042] Example 3 In view of the technical solution disclosed in Embodiment 1, the flint holder latch 211 can also be set on the slide mounted on the body 1. The slide is provided with a hand operation part and an elastic force is applied to the corresponding end of the slide. This structure can be used in lighters with flint ignition assembly 2 installed.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
