Description

Technical Field

[0001] The utility model relates to the technical field of ignition devices, in particular to a lighter with higher safety. Background Art

[0002] A lighter is a small fire-making device, mainly used for making fire, smoking, cooking and other fire-making. The main components of a lighter are the ignition mechanism and the gas storage box. When the ignition mechanism is activated, sparks burst out and shoot towards the gas area to ignite the gas. The ignition mechanism is the most active part of the evolution of the lighter and also the part with a more complex structure. According to the characteristics of the ignition mechanism, lighters can be divided into six types: flint steel wheel lighters, piezoelectric ceramic lighters, magnetic induction lighters, battery lighters, solar lighters, and microcomputer lighters. At present, the most commonly used is the piezoelectric ceramic lighter, which is widely used due to its low cost.

[0003] The existing piezoelectric ceramic lighters on the market basically use a push-type structure to ignite, and since this type of lighter is basically exposed, it is easy for ignition to occur due to accidental touching of the push-end structure used for ignition during activities such as carrying, which can easily bring safety hazards.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example: As attached Figures 1 to 8 A lighter with higher safety is shown, comprising a lighter body 1 and an ignition button 2 movably arranged on the lighter body 1, the lighter also comprising a lock plate 3, the lock plate 3 being slidably arranged on the side of the lighter body 1 along the vertical direction, and when the lock plate 3 slides, a locking position 4 fitting with the ignition button 2 and an unlocking position 5 detached from the ignition button 2 are provided on the lighter body 1 through a positioning structure. In the present embodiment, when the lock plate 3 reaches the locking position 4, the upper end of the lock plate 3 is flush with the upper end of the ignition button 2. A sliding lock structure is provided on the lighter body 1. When carrying the lighter, the lock plate 3 is slid to the locking position 4, and the lock plate 3 is positioned by the positioning structure. At this time, if the finger touches the ignition button 2 by mistake, the finger will be interfered by the resistance of the lock plate 3 while touching the ignition button 2, resulting in the failure to successfully press the ignition button 2, thereby preventing the occurrence of ignition due to accidental touch, and significantly improving the safety of the lighter. When the lighter needs to be used, it is only necessary to slide the lock plate 3 to the unlocking position 5 and position it through the positioning structure, which is very convenient to operate.

[0034] As attached Figures 4 to 7 As shown, the positioning structure includes a positioning protrusion 6 provided on the lighter body 1 and a positioning groove 7 provided on the inner side of the lock plate 3 and matched with the positioning protrusion 6. The number of the positioning grooves 7 is at least two, and the distribution direction of the plurality of positioning grooves 7 is consistent with the sliding direction of the lock plate 3. When the positioning protrusion 6 falls relatively from one of the positioning grooves 7 into the adjacent positioning groove 7, the lock plate 3 needs to overcome the resistance brought by the positioning protrusion 6, and the lock plate 3 and the positioning protrusion 6 are slightly deformed so that the positioning protrusion 6 falls into an adjacent positioning groove 7. This design can realize the positioning of the lock plate 3 at multiple positions when it slides vertically, not only in the locking position 4 and the unlocking position 5, but also in multiple other positions, so that the lock plate 3 can be slid and played, which improves its fun.

[0035] As attached Figures 4 to 7As shown, a rotation groove 8 is provided on the side of the lighter body 1, and the positioning protrusion 6 is spherical in shape. The positioning protrusion 6 is rotatably arranged in the rotation groove 8, and the positioning protrusion 6 is partially exposed outside the rotation groove 8 for matching with the positioning groove 7. The outer end opening of the rotation groove 8 can be designed as an inward-retracted opening, so as to restrict the spherical positioning protrusion 6 in the rotation groove 8. This design can reduce sliding resistance, not only improve the hand feel, but also reduce the wear of parts and components and increase their service life.

[0036] As attached Figure 7 As shown, a vertical groove 9 is further provided inside the lock plate 3, and the vertical groove 9 connects the plurality of positioning grooves 7 together, and the depth of the vertical groove 9 is less than the depth of the positioning groove 7. This design can reduce sliding resistance, not only improve the hand feel, but also reduce the wear of components and increase their service life.

[0037] As attached Figure 7 As shown, the lock plate 3 is provided with a weight-reducing groove 10. Providing the weight-reducing groove 10 on the lock plate 3 can reduce the weight of the lock plate 3, thereby reducing the weight of the lighter as a whole. In addition, the weight-reducing groove 10 processed in this embodiment is arranged on the inner side of the lock plate 3, which reduces the weight of the lock plate 3 and makes the outer surface of the lock plate 3 smoother and more beautiful.

[0038] As attached Figure 2 As shown, a guide rail 11 with a dovetail-shaped cross section is also installed on the side of the lighter body 1. The guide rail 11 extends vertically, and a guide groove 12 matching the guide rail 11 is provided on the lock plate 3. The shape of the guide groove 12 matches the shape of the guide rail 11. This design can guide the lock plate 3 so that it can move vertically stably, and at the same time, it will not separate from the lighter body 1 during the movement.

[0039] The guide rail 11 is detachably connected to the lighter body 1 by at least two screws, and in this embodiment, the upper and lower ends of the guide rail 11 are connected to the lighter body 1 by one screw respectively. Its connection structure is simple and reliable, which is not only conducive to early assembly, but also convenient for later disassembly maintenance or parts recycling.

[0040] As attached Figure 4 and attached Figure 8 As shown, at least two positioning protrusions 13 are provided on the inner side of the guide rail 11, and at least two positioning recesses 14 are provided on the lighter body 1 for matching with the positioning protrusions 13. During installation, the guide rail 11 can be positioned first, so as to facilitate the screw alignment operation for connecting the guide rail 11 and the lighter body 1.

[0041] As attached Figure 8 As shown, the guide rail 11 is provided with a plurality of reinforcing ribs 15 extending vertically. This design can improve the overall strength of the guide rail 11 and increase its service life.

[0042] In addition, the front shape of the locking plate 3 can be designed to be the same as the front shape of the lighter body 1, which can make the appearance more beautiful and the feel better.
