[0002] As a small fire-making device, lighters are mainly used for smoking, cooking and other fire-making. With the development of lighter manufacturing technology, the types of flames of lighters are constantly increasing, and more and more people are looking for lighters with better appearance, more ignition functions and more comfortable feel in addition to the fire-making function.

[0003] The Chinese utility model patent with authorization announcement number CN219530919U provides a liftable lighter, including an outer casing, an inner casing slidably arranged in the outer casing and a head cover, the push block of the inner casing passes through the outer casing, the head cover is coaxially pivoted with the steel wheel of the inner casing, an elastic locking plate is installed on the inner casing, and a locking hook is provided on the elastic locking plate. When the inner casing is completely located in the outer casing, the locking hook is hooked and connected with the hook foot of the head cover. After the inner casing is pushed out of the outer casing, the locking hook is automatically separated from the hook foot, and the head cover is automatically flipped open under the action of the elastic driving member.

[0004] The above-mentioned lighter realizes the automatic flipping and opening of the head cover by setting an elastic locking plate and an elastic driving member, but this structure requires the additional production of elastic locking plates of specific shapes and sizes during production, and increases the difficulty of assembly. The applicant has designed a new lighter with a head cover that can automatically pop out, and makes its head cover pop-up structure simpler, more convenient to assemble, saves costs, and improves production efficiency. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and provide a lighter with a head cover that can be automatically ejected. The technical solution adopted by the utility model is as follows:

[0006] A lighter with an automatically pop-up head cover comprises a shell, a main body slidably arranged in the shell, and a head cover, wherein the head cover is provided with an installation cavity, in which a second elastic member and a limit body are arranged, and the limit body has a guiding inclined surface or an arc surface (a person skilled in the art may set the limit body to a sphere or a block with a triangular or trapezoidal cross-section); the limit body has a locking state in which it extends out of the installation cavity under the push of the second elastic member and is limited in a positioning hole / groove on the inner wall of the shell, and the limit body has an unlocking state in which, under the action of an external force, its guiding inclined surface or arc surface is squeezed against the inner wall of the shell, thereby causing the limit body to compress the second elastic member and retract into the installation cavity; when the limit body is in the unlocking state, the head cover can slide relative to the shell; when the head cover slides to the outside of the shell, the elastic driving member drives the head cover to flip and open relative to the main body.

[0007] One implementation manner may be: the elastic driving member is a torsion spring connecting the main body and the head cover, the second elastic member is a spring, and the limiting body is a sphere.

[0008] Furthermore, the elastic driving member is arranged at one end of the head cover away from the installation cavity. When the head cover and the main body are closed, the limit body is in a locked state and the elastic driving member is in a compressed state; when the head cover is opened relative to the main body, the elastic driving member is in an extended state.

[0009] Preferably, a positioning cylinder is arranged in the installation cavity, and the positioning cylinder is nested with the installation cavity to accommodate the second elastic member and the limiting body and limit the two. The positioning cylinder has an opening at one end away from the installation cavity, and the diameter of the opening is smaller than the diameter of the limiting body, so that the limiting body has a locking state in which the second elastic member pushes the lower part out of the opening and is limited in the positioning hole / groove on the inner wall of the shell; during assembly, the second elastic member and the limiting body can be assembled with the positioning cylinder first, and then placed together in the installation cavity.

[0010] Furthermore, one end of the positioning tube away from the installation cavity extends out of the installation cavity and extends circumferentially to form an annular protrusion.

[0011] Those skilled in the art may provide threads or the like on the outer circumference of the positioning tube to connect it to the installation cavity in a detachable manner, or may connect it to the installation cavity through interference fit.

[0012] Preferably, a travel groove is provided on the shell, and the main body is provided with a sliding protrusion passing through the travel groove. The sliding protrusion slides in the travel groove under the action of external force and drives the main body and the head cover to slide relative to the shell.

[0013] Furthermore, the head cover also includes a pushing portion rotatably connected to the main body and away from the mounting cavity. The pushing portion rotates and presses the transmission portion downward when the head cover is opened relative to the main body. The transmission portion further presses the movable end of the seesaw to cause the seesaw to tilt up to open the air valve. The movable end of the seesaw is cooperated with a first elastic member. The first elastic member pushes the movable end of the seesaw when the head cover is closed relative to the main body, so that the seesaw is reset and the air valve is closed.

[0014] A first cavity for accommodating a first elastic member and a second cavity for accommodating a limit block are provided below the movable end of the seesaw, and the limit block includes a second limit portion cooperating with the seesaw and a first limit portion extending into the first elastic member; the first elastic member is limited between the second limit portion and the first cavity, and drives the limit block to slide along the second cavity to push the seesaw.

[0015] The lighter also includes a gas storage structure, a gas outlet structure, and an ignition structure, wherein the ignition structure includes a micro switch and an ignition needle controlled by the micro switch; when the head cover and the main body are located inside the shell, the bottom of the main body abuts against the bottom of the shell to keep the micro switch closed; when the main body slides and drives the head cover to expose the shell, the elastic driving member drives the head cover to flip open relative to the main body, and the pushing part presses the transmission part downward under the drive of the head cover, and the transmission part further presses the movable end of the seesaw to make the seesaw tilt up to open the gas valve of the gas storage structure, and at the same time, the bottom of the main body moves away from the bottom of the shell to open the micro switch, and the ignition needle ignites near the gas outlet structure.

[0016] The beneficial effects of the utility model are as follows: the device arranges a second elastic member and a limiting body in the installation cavity on the head cover, and the limiting body cooperates with the positioning hole / groove on the inner wall of the shell under the action of the second elastic member, so that the limiting body has a locking state of extending out of the installation cavity and being limited in the positioning hole / groove on the inner wall of the shell, and, when the head cover slides relative to the shell, the limiting body has an unlocking state of compressing the second elastic member and retracting into the installation cavity. When the limiting body is in the unlocking state, the head cover can slide to the outside of the shell. At this time, the head cover is no longer constrained by the shell, and automatically flips open relative to the main body under the action of the elastic driving member. When using it, the user only needs to apply external force to make the main body of the lighter slide out of the shell, and the head cover can automatically flip open. The structure is simple, the assembly is convenient, and the use is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] like Figure 1-2As shown, a double straight-impulse lighter with a head cover that can automatically pop out includes a shell 2, a main body 3 slidably arranged in the shell 2, and a head cover 1, the head cover 1 has an installation cavity 101, and a second elastic member 15 and a limiting body 16 are arranged in the installation cavity 101, and the limiting body 16 has a guiding inclined surface or an arc surface (a person skilled in the art can set the limiting body 16 to a block with a triangular or trapezoidal cross-section); the limiting body 16 has a locked state in which it extends out of the installation cavity 101 under the push of the second elastic member 15 and is limited in a positioning hole / groove 201 on the inner wall of the shell 2, and the limiting body 16 has an unlocked state in which the guiding inclined surface or the arc surface is squeezed against the inner wall of the shell 2 under the action of an external force, thereby causing the limiting body 16 to compress the second elastic member 15 and retract into the installation cavity 101. When the limiting body 16 is in the unlocked state, the head cover 1 can slide relative to the shell 2; when the head cover 1 slides to the outside of the shell 2, the elastic driving member drives the head cover 1 to flip and open relative to the main body 3.

[0029] In this embodiment, the elastic driving member is a torsion spring connecting the main body 3 and the head cover 1, the second elastic member 15 is a spring, and the limiting body 16 is a sphere.

[0030] The elastic driving member is arranged at one end of the head cover 1 away from the installation cavity 101. When the head cover 1 and the main body 3 are closed, the limit body 16 is in a locked state and the elastic driving member is in a compressed state; when the head cover 1 is opened relative to the main body 3, the elastic driving member is in an extended state.

[0031] A positioning cylinder 17 is arranged in the installation cavity 101, and the positioning cylinder 17 is nested with the installation cavity 101 to accommodate the second elastic member 15 and the limiting body 16 and limit the two. The positioning cylinder 17 has an opening at one end away from the installation cavity 101, and the diameter of the opening is smaller than the diameter of the limiting body 16, so that the limiting body 16 has a locked state in which the lower part of the second elastic member 15 pushes out of the opening and is limited in the positioning hole / groove 201 on the inner wall of the shell 2; the positioning cylinder 17 extends out of the installation cavity 101 at one end away from the installation cavity 101 and extends circumferentially to form an annular protrusion 171, and the annular protrusion 171 contacts the outer surface of the head cover 1.

[0032] The housing 2 is provided with a travel groove 202 , and the main body 3 is provided with a sliding protrusion 301 passing through the travel groove 202 . The sliding protrusion 301 slides in the travel groove 202 under the action of external force and drives the main body 3 and the head cover 1 to slide relative to the housing 2 .

[0033] The head cover 1 also includes a push portion 11 rotatably connected to the main body 3 away from the installation cavity 101. The push portion 11 rotates and presses downwardly against the transmission portion 12 when the head cover 1 is opened relative to the main body 3. The transmission portion 12 further presses the movable end of the seesaw 6 to tilt the seesaw 6 to open the air valve 7, so that the air storage structure is connected to the air outlet structure (double direct-impact gas channel 8); the movable end of the seesaw 6 is cooperated with a first elastic member 14. The first elastic member 14 pushes the movable end of the seesaw 6 when the head cover 1 is closed relative to the main body 3, so that the seesaw 6 is reset and the air valve 7 is closed.

[0034] A first cavity for accommodating a first elastic member and a second cavity for accommodating a limit block 13 are provided below the movable end of the rocker 6.

[0035] The lighter also includes a gas storage structure, a gas outlet structure, and an ignition structure. The ignition structure includes a micro switch and an ignition needle controlled by the micro switch. When the head cover 1 and the main body 3 are located inside the shell 2, the bottom of the main body 3 abuts against the bottom of the shell 2 to keep the micro switch closed.

[0036] When the main body 3 slides and drives the head cover 1 to expose the outer shell 2, the elastic driving member drives the head cover 1 to flip open relative to the main body 3, and the push portion 11 is driven by the head cover 1 to press the transmission portion 12 downward, and the transmission portion 12 further presses the movable end of the rocker 6 to make the rocker 6 tilt up to open the gas valve 7 of the gas storage structure. At the same time, the bottom of the main body 3 is away from the bottom of the outer shell 2 to open the micro switch, and the ignition needle ignites near the gas outlet structure (double straight gas channel 8).

In this embodiment, the second elastic member 15 is a spring and the limiting body 16 is a sphere, so that it can gradually retract into the mounting cavity 101 under the push action of the inner wall of the shell 2.

[0039] A positioning hole 201 is formed in the shell 2 at a position corresponding to the limiting body 16, and a torsion spring is arranged between the head cover 1 and the main body 3. When the main body 3 is retracted into the shell 2, the limiting body 16 is located in the positioning hole 201 at the lower limit of the push of the second elastic member 15. When the user pushes the sliding protrusion 301 from the outside to slide in the travel groove 202 and thereby causes the main body 3 and the head cover 1 to slide relative to the shell 2, the limiting body 16 is retracted into the installation cavity 101 and moves upward under the pressure of the inner wall of the shell 2 until the head cover 1 drives the limiting body 16 to move out of the upper opening of the shell 2. At this time, the torsion spring drives the head cover 1 to flip relative to the main body 3, and the head cover 1 is opened to expose the ignition cavity 102.

[0040] The main body 3 has a gas storage structure, a gas outlet structure, and an ignition structure. The gas outlet structure includes a gas distribution chamber 42. The gas distribution chamber 42 has an air inlet channel 41 connected to the gas storage structure and an air outlet 51 matched with the ignition structure, and the air inlet channel 41 is connected to a plurality of air outlets 51 at the same time through the gas distribution chamber 42; the air inlet channel 41 is arranged on the bottom plate formed by the middle frame 4, and the air outlet 51 is arranged on the distribution plate 5 buckled with the bottom plate, and a gas distribution chamber 42 is formed between the bottom plate and the distribution plate 5; the plurality of air outlets 51 are arranged linearly on the distribution plate 5, and include six air outlets 51 arranged at intervals.

A first positioning groove 43 is arranged on the surface of the bottom plate, and a first positioning protrusion 52 is arranged on the lower end surface of the distribution plate 5. A sealing ring is embedded in the first positioning groove 43. The bottom plate and the distribution plate 5 are buckled together to form a gas distribution chamber 42 therebetween. A first positioning protrusion 52 is arranged on the upper side of the sealing ring and limits the sealing ring.

[0042] The bottom plate is integrated with the middle frame 4 of the lighter, the air inlet channel 41 is connected to the gas valve 7 of the gas storage structure, and the middle frame 4 also includes a support portion 46 arranged on the side of the bottom plate, and the support portion 46 limits the side of the distribution plate 5. The distribution plate 5 includes a first positioning protrusion 52 extending from its lower end surface, and the first positioning protrusion 52 is embedded in the positioning cavity 461 formed by the support portion 46, and a side of the first positioning protrusion 52 close to the bottom plate is provided with a hollow groove 53 connected to a plurality of gas outlets 51, and the hollow groove 53 cooperates with the bottom plate to form a gas distribution cavity 42.

[0043] The inner wall of the support portion 46 is provided with a second positioning protrusion 44, and the distribution plate 5 has a second positioning groove 54 that cooperates with the second positioning protrusion 44. The ignition structure includes a micro switch located below the middle frame 4, and a through hole is provided on the second positioning protrusion 44.

[0044] Regarding the micro switch, when the head cover 1 and the main body 3 are located inside the shell 2, the bottom of the main body 3 abuts against the bottom of the shell 2 so that the pressing part of the micro switch abuts against the inner wall of the bottom of the shell 2 and remains closed. When the main body 3 slides and drives the head cover 1 to expose the shell 2, the bottom of the main body 3 moves away from the bottom of the shell 2, causing the pressing part of the micro switch to pop out, causing the ignition needle to ignite.

[0045] When the user pushes the sliding protrusion 301 to Figure 5 When in the position shown, the head cover 1 is flipped open relative to the main body 3 under the drive of the torsion spring, driving the push part 11 to rotate and press the transmission part 12 downward, and the transmission part 12 further presses the movable end of the seesaw 6 to make the seesaw 6 tilt up to open the air valve 7, connect the air path from the air storage structure to the air intake channel 41, and at the same time turn on the micro switch for ignition; the movable end of the seesaw 6 is equipped with a first elastic member 14, and the first elastic member 14 pushes the movable end of the seesaw 6 when the head cover 1 is closed relative to the main body 3 (the transmission part 12 moves up), so that the seesaw 6 is reset and the air valve 7 is closed. At this time, the head cover 1 and the main body 3 are completely retracted into the shell 2, and the pressing part of the micro switch is against the inner wall of the bottom of the shell 2 to keep it closed.
