Description

Technical Field

[0001] The utility model relates to the technical field of lighters, and specifically relates to a lighter. Background Technique

[0002] A lighter is a small fire-taking device, mainly used for taking fire, smoking, and also for cooking and other fire-taking. The main components of a lighter are a firing mechanism and a gas storage tank. When the firing mechanism operates, a spark bursts out and shoots towards the gas area to ignite the gas. The firing mechanism is the most active part in the evolution of lighters and is also the part with a relatively complex structure.

[0003] For example, the Chinese utility model patent with the publication number CN220551936U. This application relates to the technical field of lighters and discloses a lighter, which includes a lighter housing, an air outlet valve installed on the lighter housing, a vaporization furnace installed above the air outlet valve, a fire-adjusting ring rotatably installed on the lighter housing for adjusting the air outlet valve, and a gland assembly installed on the lighter housing and used to push up the valve needle of the air outlet valve. An air intake side hole is opened on the outer side wall of the vaporization furnace near the air intake end, and a gas-blocking component is arranged outside the vaporization furnace. When the lighter is in the ignition state, the horizontal projection of the air intake side hole is located above the gas-blocking component. When the lighter is in the extinguished state, the horizontal projection of the air intake side hole is located on the side wall of the gas-blocking component. This application can improve the extinguishing speed of the lighter.

[0004] In order to enable the lighter to be used repeatedly, an air filling hole is usually provided at the bottom of the lighter and a spring assembly is provided to block the air filling hole. When filling gas, an air filling tank is needed to push the spring assembly to connect the air filling hole, so as to add gas into the gas storage tank. However, before filling gas, a hard object needs to be found to push the spring assembly to exhaust gas, and the operation is very inconvenient. Therefore, a lighter is proposed to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a lighter, which has the advantage of being convenient for exhausting gas and solves the problem that a hard object needs to be found to push the spring assembly to exhaust gas before filling gas.

[0006] To achieve the above object, the utility model provides the following technical solution: A lighter, including a gas storage tank, an upper seal is fixed on the top of the gas storage tank, a firing mechanism penetrating into the interior of the gas storage tank is arranged inside the upper seal, a lower seal is fixed on the bottom of the gas storage tank, an outer shell is fixed on the outer surface of the gas storage tank, the lower seal is located inside the outer shell, and a hinged cover is hinged on the top of the outer shell;

[0007] The upper seal is located inside the hinged cover. A protective component is hinged to the bottom of the outer shell. The protective component is used to protect the lower seal. A return spring, a limit block and a sealing plate are respectively fixed inside the lower seal. The bottom of the return spring is fixed to the sealing plate. The bottom of the sealing plate is fixed with a connecting rod that penetrates through the limit block and extends to the bottom of the lower seal.

[0008] The protective component includes a protective cover, a positioning block, a hinged block, a connecting hook and a connecting hook. The bottom of the outer shell is hinged to the protective cover. The top of the protective cover is fixed with a positioning block inserted into the lower seal. The top of the protective cover is slidably connected to the hinged block. The top of the hinged block is hinged to the connecting hook. The top of the connecting hook is fixed to the connecting hook. The connecting hook is fixed to the connecting rod.

[0009] By adopting this technical solution, when the lower seal faces downward, the positioning plate will move to the bottom of the connecting hook due to gravity, so that when the connecting hook moves downward, it will pull the connecting hook. When there is no need to exhaust, the lower seal is turned upward. At this time, the positioning plate moves to fit with the hinged plate due to gravity, so that the connecting hook will not contact the positioning plate when it moves, making the whole more practical.

[0010] Furthermore, a sealing ring is fixed to the top of the lower seal, and a sealing groove adapted to the sealing ring is opened at the bottom of the air storage tank.

[0011] By adopting this technical solution, through the arranged sealing ring and sealing groove, the sealing performance of the connection between the lower seal and the air storage tank can be effectively improved.

[0012] Furthermore, both the positioning block and the connecting rod are deformable plastic parts, and a grasping groove is opened on the right side of the protective cover.

[0013] By adopting this technical solution, being set as deformable plastic parts makes the positioning block and the connecting rod produce a certain deformation when a relatively large force is used, and reset when no force is used.

[0014] Furthermore, an extension rod slidably connected to the protective cover is fixed to the bottom of the hinged block, and an extension block slidably connected to the protective cover is fixed to the outer surface of the extension rod.

[0015] By adopting this technical solution, the arranged extension rod and extension block enable the hinged block to slide left and right on the top of the protective cover and will not separate.

[0016] Furthermore, four communication grooves are opened inside the lower seal, and the width of the communication groove is greater than the width of the sealing plate.

[0017] By adopting this technical solution, when the sealing plate moves to the middle of the communication groove, the sealing plate cannot block the lower seal, so that the inside of the lower seal is communicated.

[0018] Furthermore, sliding blocks are fixed on both the front and rear sides of the sealing plate, and sliding grooves for sliding connection with the sliding blocks are provided inside the lower seal.

[0019] By adopting this technical solution, the provided sliding blocks and sliding grooves effectively improve the moving stability of the sealing plate.

[0020] Furthermore, both the sliding block and the sealing plate are closely attached to the inner wall of the lower seal, and the limiting block is a hollow annular block.

[0021] By adopting this technical solution, through the close attachment, the overall sealing performance is effectively improved, and the provided limiting block can limit the moving direction of the connecting rod, so that the connecting rod can only move up and down.

[0022] Furthermore, the connecting hook includes a hinged plate and a positioning plate. The hinged plate is fixed to the connecting rod, and the inside of the hinged plate is hinged to the positioning plate.

[0023] By adopting this technical solution, the hinge between the positioning plate and the hinged plate is a hinge with a flipping limit, and the maximum flipping angle of the positioning plate is [angle value].

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] 1. For this lighter, when it is necessary to exhaust the inside of the gas storage tank, through the provided protection component, when pulling the protection component, the sealing plate inside the lower seal will be pulled downwards, so that the inside of the gas storage tank is communicated with the inside of the lower seal, and thus the gas storage tank can be conveniently exhausted, without the need to find a hard object to push the sealing plate, effectively improving the convenience of exhaust, and making the whole more practical.

[0026] 2. For this lighter, the provided protection component can protect the lower seal, and when pulling the protection component to move the sealing plate downwards, it is a labor-saving structure, which can effectively reduce the pulling force required, and the provided hinged cover can protect the upper seal, and the overall structure is simple, making the whole more durable.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Please refer to Figures 1 to 4 , in this embodiment, a lighter includes a gas storage tank 1. An upper seal 2 is fixed to the top of the gas storage tank 1. A firing mechanism 3 penetrating into the interior of the gas storage tank 1 is arranged inside the upper seal 2. The firing mechanism 3 is a prior art, and the ignition principle thereof will not be elaborated here. A lower seal 4 is fixed to the bottom of the gas storage tank 1. A sealing ring 15 is fixed to the top of the lower seal 4. A sealing groove adapted to the sealing ring 15 is formed in the bottom of the gas storage tank 1. By providing the sealing ring 15 and the sealing groove, the sealing performance of the connection between the lower seal 4 and the gas storage tank 1 can be effectively improved. An outer shell 5 is fixed to the outer surface of the gas storage tank 1. The lower seal 4 is located inside the outer shell 5. A hinged cover 6 is hinged to the top of the outer shell 5.

[0036] In addition, the upper seal 2 is located inside the hinged cover 6. A protective component 7 is hinged to the bottom of the outer shell 5. The protective component 7 is used to protect the lower seal 4. A return spring 8, a limit block 9 and a sealing plate 10 are respectively fixed inside the lower seal 4. The bottom of the return spring 8 is fixed to the sealing plate 10. Four communication grooves 12 are formed inside the lower seal 4. The width of the communication groove 12 is greater than the width of the sealing plate 10. When the sealing plate 10 moves to the middle of the communication groove 12, the sealing plate 10 cannot block the lower seal 4, so that the inside of the lower seal 4 is communicated.

[0037] Furthermore, sliding blocks 13 are fixed to both the front and rear sides of the sealing plate 10. A sliding groove 14 slidably connected to the sliding block 13 is formed inside the lower seal 4. The provided sliding block 13 and sliding groove 14 effectively improve the moving stability of the sealing plate 10. The sliding block 13 and the sealing plate 10 are both in close contact with the inner wall of the lower seal 4. Through the close contact, the overall sealing performance is effectively improved. A connecting rod 11 passing through the limit block 9 and extending to the bottom of the lower seal 4 is fixed to the bottom of the sealing plate 10. The limit block 9 is a hollow annular block. The provided limit block 9 can limit the moving direction of the connecting rod 11, so that the connecting rod 11 can only move up and down.

[0038] Generally speaking, the outer shell 5, the hinged cover 6 and the protective component 7 can protect the internal structure. The provided sealing plate 10 can block the inner cavity of the lower seal 4, and the provided return spring 8 improves the stability of the blockage.

[0039] Please refer to Figures 5 to 6 , in this embodiment, the protective component 7 includes a protective cover 701, a positioning block 702, a hinge block 703, a connecting hook 704 and a connecting hook 705. The bottom of the outer shell 5 is hinged to the protective cover 701. A grasping groove 706 is formed on the right side of the protective cover 701. A positioning block 702 inserted into the lower seal 4 is fixed to the top of the protective cover 701. The top of the protective cover 701 is slidably connected to the hinge block 703. A extension rod fixed to the bottom of the hinge block 703 and slidably connected to the protective cover 701 is provided. An extension block slidably connected to the protective cover 701 is fixed to the outer surface of the extension rod. The provided extension rod and extension block enable the hinge block 703 to slide left and right on the top of the protective cover 701 and not separate.

[0040] Supplementary to this, the top of the hinge block 703 is hinged to the connection hook 704, the top of the connection hook 704 is fixed to the connection hook 705, the connection hook 705 is fixed to the connecting rod 11. The connection hook 705 includes a hinge plate 7051 and a positioning plate 7052. The hinge plate 7051 is fixed to the connecting rod 11, the inside of the hinge plate 7051 is hinged to the positioning plate 7052. The hinge between the positioning plate 7052 and the hinge plate 7051 is a hinge with a flipping limit, and the maximum flipping angle of the positioning plate 7052 is 90 degrees.

[0041] It should be noted that both the positioning block 702 and the connecting rod 11 are deformable plastic parts. Being set as deformable plastic parts enables a certain deformation of the positioning block 702 and the connecting rod 11 when a relatively large force is applied, and they will reset when no force is applied.

[0042] Generally speaking, when the lower seal 4 faces downward, the positioning plate 7052 will move to the bottom of the connection hook 704 due to gravity. Thus, when the connection hook 704 moves downward, it will pull the connection hook 705. When exhaust is not required, the lower seal 4 is turned upward. At this time, the positioning plate 7052 moves to fit with the hinge plate 7051 due to gravity, so that when the connection hook 704 moves, it will not contact the positioning plate 7052, making the whole more practical.

[0043] All electrical components mentioned in the text are electrically connected to the controller and the power supply. The control mode of the present utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0044] The working principle of the above embodiment is as follows:

[0045] (1) When it is necessary to exhaust the lighter, the protective cover 701 is pulled downward through the grasping groove 706, causing the positioning block 702 to deform and lose the insertion connection with the lower seal 4. Thus, the protective cover 701 can rotate around the hinge point with the outer shell 5. When the outer shell 5 rotates, the hinge block 703, the connection hook 704, the connection hook 705, the connecting rod 11, and the sealing plate 10 will move downward against the prestress of the return spring 8. Since the hinge block 703 is slidably connected to the protective cover 701 and hinged to the connection hook 704, the protective cover 701 that moves in an arc can maintain the connection with the sealing plate 10. When the sealing plate 10 moves downward to coincide with the communication groove 12, the outside will be connected to the gas storage tank 1, so that exhaust can be conveniently carried out. The overall structure is simple, effectively improving the overall practicality.

[0046] (2)When inflation is required, since the protective cover 701 is flipped downward by a certain arc, the user can hold the exposed connecting rod 11. At this time, gently push the protective cover 701 upward and push the connecting rod 11 to the left to cause a certain deformation of the connecting rod 11, so that the connecting hook 704 can be separated from the connecting hook 705. At this time, under the prestress of the return spring 8, the sealing plate 10, the connecting rod 11 and the connecting hook 705 will be reset, and the protective cover 701 can be completely flipped to expose the inner lower seal 4. At this time, the air replenishing tank can be used to replenish air. After the air replenishment is completed, push the hinge block 703 to the left. After the hinge block 703 is reset, push the protective cover 701 upward to make the protective cover 701 protect the lower seal 4 again. During the movement of the protective cover 701, the connecting hook 704 will contact the connecting hook 705 again. At this time, since the return spring 8 has a certain rigidity to limit the movement of the connecting hook 705, the connecting hook 704 will push the positioning plate 7052 to flip upward along the hinge point, so that the connecting hook 704 can move to the top of the positioning plate 7052. When the connecting hook 704 loses contact with the positioning plate 7052, under the action of gravity at this time, the positioning plate 7052 will be reset, so that the connecting hook 705 is connected to the connecting hook 704, making it convenient for subsequent use.
