Description

Technical Field

[0001] This utility model relates to the field of lighter technology, and more specifically, to a gas lighter with a flat flame. Background Technology

[0002] A lighter is a small fire-starting device, primarily used for starting a fire, lighting cigarettes, and also for cooking and other purposes. Lighters are classified into several types based on the type of ignition unit they use: gas lighters, kerosene lighters, electric lighters, and arc lighters. Gas lighters mainly consist of an ignition mechanism and a gas tank. The principle of a lighter is that the ignition mechanism activates, sending a spark towards the gas supply to ignite it.

[0003] Most lighters currently on the market have a common flame shape, with very few involving other types of flames. Based on this situation, some manufacturers have modified lighters with flame shapes to produce lighters with flat flames. However, lighters with flat flames are designed after significant modifications to the structure of lighters on the market, and their structure is relatively complex. As a result, the production cost of these flat flame lighters is much higher than that of lighters on the market, leading to a generally higher selling price and making them difficult to popularize. Utility Model Content

[0004] This utility model overcomes the shortcomings of the prior art. Its structure is reasonably designed. By integrally molding the atomizing chamber and the diversion groove, the two parts can be manufactured as one piece, which greatly reduces the production cost.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A gas lighter with a flat flame includes a housing. Inside the housing are an ignition component, a gas box with a gas control valve, a control component, and a flame-emitting component. The control component controls the ignition of the ignition component and the switching of the gas control valve. The gas control valve is connected to the flame-emitting component via a gas pipe. The housing has an air inlet and a waist-shaped flame-emitting hole corresponding to the flame-emitting component. The flame-emitting component includes an integrally formed distribution groove and an atomizing chamber. The atomizing chamber includes a connecting through hole connected to the gas pipe, a connecting hole communicating with the connecting through hole, an air inlet communicating with the connecting hole and communicating with the air inlet, and a communicating hole communicating with the air inlet and the distribution groove. A flow guide is provided inside the distribution groove. The flow guide and the bottom of the distribution groove form a bottom channel communicating with the communicating hole. The outer periphery of the flow guide has a flow guide profile on both sides. The flame-emitting component is sleeved on the distribution groove. A flow guide gap communicating with the bottom channel is formed between the flow guide profile, the inner wall of the flame-emitting component, and the inner wall of the distribution groove.

[0007] By adopting the above technical solution, the atomizing chamber and the diversion groove are integrally molded, allowing for the integrated manufacturing of both components. This significantly reduces production costs and better ensures gas flow between them, preventing the need for sealing rings when they are separate and the potential for gas leakage during prolonged use. Specifically, the connecting hole in the atomizing chamber can be connected to a gas pipe connector. The gas pipe connector can be a standard connector or have tiny nozzle holes to accelerate the gas, achieving a direct flame effect. Furthermore, the flame outlet is a cylindrical elliptical ceramic component. A flow guide gap is formed between the inner wall of the ceramic component and the flow guide contour, as well as between the inner wall of the diversion groove and the flow guide contour. This causes the gas to flow out in a ring shape through these gaps, and upon ignition, it produces a flat, elliptical flame from the waist-shaped flame outlet.

[0008] Preferably, the volume of the air inlet is larger than the volume of the connecting through hole and the connecting hole.

[0009] By adopting the above technical solution, the air intake volume of the air inlet can be greatly increased, allowing the gas flowing out of the air box to mix more fully with the air, effectively overcoming the difficulty of ignition caused by the thin oxygen in high-altitude areas.

[0010] Preferably, the flame outlet is provided with a waist-shaped constriction corresponding to the waist-shaped flame outlet hole, and the flame outlet is provided with an arc-inducing port, the position of which is higher than that of the guide component.

[0011] By adopting the above technical solution, the waist-shaped constriction setting allows the flame ignited in the ignition zone located at the inner arc inlet of the flame outlet, i.e. above the guide component, to be lifted one step to be shaped and accelerated, resulting in a flat oval flame produced from the waist-shaped flame outlet having higher forming quality.

[0012] Preferably, the housing includes an outer shell, a fixed base disposed within the outer shell, a middle frame disposed within the outer shell and capable of sliding up and down relative to the fixed base, and a cover disposed on the middle frame and linked with the middle frame. The air inlet is disposed on the outer shell, and the waist-shaped flame outlet is disposed on the cover.

[0013] By adopting the above technical solution, the cover and the middle frame can slide up and down relative to the outer shell and the fixed base. When the cover and the middle frame move down to the position where ignition can be operated, the air inlet on the outer shell is opposite to the air inlet hole, so that the gas can directly enter the air inlet hole from the air inlet, further ensuring the air intake.

[0014] Preferably, the ignition assembly includes a piezoelectric electron, and the control assembly includes a pressure block corresponding to the piezoelectric electron on the cover or the middle frame, a rocker plate on the gas control valve, and a pressing part corresponding to the rocker plate on the middle frame. The cover and the middle frame move downward relative to the fixed seat, and the pressure block presses against the piezoelectric electron while the pressing part presses against the rocker plate.

[0015] By adopting the above technical solution, a wire is connected to the piezoelectric electron and enters the arc ignition port. The pressure block moves down and presses the piezoelectric electron to generate an electric arc. The pressing part presses against the rocker plate and causes the gas control valve to open. Gas flows from the gas box into the ignition component. With this setting, the ignition action can be achieved by sliding the cover down. The operation is simple and the triggering structure is stable and efficient.

[0016] Preferably, an elastic element connects the fixed base and the cover, a first guide structure is provided between the middle frame and the fixed base, and a second guide structure is provided between the middle frame and the outer shell.

[0017] By adopting the above technical solution, the elastic element can be a spring, which plays a role in restoring the cover and the middle frame after they slide down. The first guide structure can be a strip groove and a guide post structure located in the strip groove. The second guide structure can be a slide rail and a slide groove structure, which can ensure the guiding stability of the middle frame when it slides.

[0018] The beneficial effects of this utility model are:

[0019] This invention integrates the atomizing chamber and the diversion channel into a single unit, thereby significantly reducing production costs. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-8 As shown, a gas lighter with a flat flame includes a housing 1. Inside the housing 1 are an ignition assembly 2, a gas box 3 with a gas control valve 31, a control assembly 4, and a flame outlet component 5. The control assembly 4 controls the ignition of the ignition assembly 2 and the opening and closing of the gas control valve 31. The gas control valve 31 is connected to the flame outlet component 5 via a gas pipe 32. The housing 1 has an air inlet 16 and a waist-shaped flame outlet hole 11 corresponding to the flame outlet component 5. The flame outlet component 5 includes an integrally formed flow channel 6 and an atomizing chamber 7. The atomizing chamber 7 includes a connecting through hole 71 connected to the gas pipe 32 and a connecting through hole 71 connected to the gas pipe 32. The system includes a connecting hole 72 connected to the connecting hole 71, an air inlet 73 connected to the connecting hole 72 and connected to the air inlet 16, and a connecting hole 74 connecting the air inlet 73 and the diversion groove 6. A guide member 61 is provided inside the diversion groove 6. The guide member 61 and the bottom of the diversion groove form a bottom channel 62 that communicates with the connecting hole 74. Guide contours 63 are provided on both sides of the outer periphery of the guide member 61. A flame outlet member 8 is sleeved on the diversion groove 6. A guide gap 64 that communicates with the bottom channel 62 is formed between the inner wall of the guide contour 63 and the flame outlet member 8 and the inner wall of the diversion groove 6.

[0031] By adopting the above technical solution, the atomizing chamber 7 and the diversion groove 6 are integrally molded, which can manufacture the two components as a single unit, greatly reducing production costs and better ensuring gas flow between them. This prevents the need for sealing rings when the two are separate and avoids potential gas leakage during long-term use. Specifically, the connecting through hole 71 of the atomizing chamber 7 can be connected to the connector 33 of the gas pipe 32. The connector 33 of the gas pipe 32 can be a regular connector 33 or have tiny nozzle holes to accelerate the gas and achieve a direct flame effect. Furthermore, the flame outlet 8 is specifically an elliptical cylindrical ceramic component. A flow guide gap 64 is formed between the inner wall of the ceramic component and the flow guide contour 63, and a flow guide gap 64 is also formed between the inner wall of the diversion groove 6 and the flow guide contour 63. This allows the gas to flow out in a ring shape through the gaps, and after ignition, it produces a flat elliptical flame from the waist-shaped flame outlet 11.

[0032] The volume of the air inlet 73 is larger than that of the connecting through hole 71 and the connecting hole 72. This design allows the air intake of the air inlet 73 to be greatly increased, so that the gas flowing out of the air box 3 can be mixed more thoroughly with the air, effectively overcoming the difficulty of ignition caused by the thin oxygen in high-altitude areas.

[0033] Among them, the flame outlet 8 is provided with a waist-shaped constriction 81 corresponding to the waist-shaped flame outlet 11, and the flame outlet 8 is provided with an arc initiation port 82. The position of the arc initiation port 82 is higher than that of the guide member 61. The setting of the waist-shaped constriction 81 allows the flame ignited in the ignition zone located at the arc initiation port 82 inside the flame outlet 8, that is, above the guide member 61, to be lifted one step to be shaped and accelerated, so that the flat oval flame produced from the waist-shaped flame outlet 11 has a higher forming quality.

[0034] Furthermore, the housing 1 includes an outer shell 12, a fixed base 13 disposed within the outer shell 12, a middle frame 14 disposed within the outer shell 12 and capable of sliding up and down relative to the fixed base 13, and a cover 15 disposed on the middle frame 14 and linked with the middle frame 14. An air inlet 16 is disposed on the outer shell 12, and an oblong flare hole 11 is disposed on the cover 15. This arrangement allows the cover 15 and the middle frame 14 to slide up and down relative to the outer shell 12 and the fixed base 13. When the cover 15 and the middle frame 14 move down to the position where ignition can be operated, the air inlet 16 on the outer shell 12 is opposite to the air inlet 73, allowing gas to directly enter the air inlet 73 from the air inlet 16, further ensuring the air intake. The air inlet 16 is disposed on both sides of the outer shell 12.

[0035] The ignition assembly 2 includes a piezoelectric electron 21, and the control assembly 4 includes a pressure block 41 corresponding to the piezoelectric electron 21 on the cover 15 or the middle frame 14, a rocker plate 42 on the gas control valve 31, and a pressing part 43 corresponding to the rocker plate 42 on the middle frame 14. The cover 15 and the middle frame 14 move downward relative to the fixed seat 13. The pressure block 41 presses against the piezoelectric electron 21 while the pressing part 43 presses against the rocker plate 42. The piezoelectric electron 21 is connected to a wire that enters the arc ignition port 82. The downward movement of the pressure block 41 presses the piezoelectric electron 21 to generate an electric arc, while the pressing part 43 presses against the rocker plate 42 and causes the gas control valve 31 to open. Gas flows from the gas box 3 into the ignition component 5. With this configuration, the ignition action can be achieved by operating the cover 15 to slide down. The operation is simple and the triggering structure is stable and efficient.

[0036] Specifically, an elastic element 44 is connected between the fixed base 13 and the cover 15, a first guide structure 45 is provided between the middle frame 14 and the fixed base 13, and a second guide structure 46 is provided between the middle frame 14 and the outer shell 12. The elastic element 44 can be a spring, which plays a role in restoring the cover 15 and the middle frame 14 after they slide down. The first guide structure 45 can be a strip groove and a guide post structure located in the strip groove. The second guide structure 46 can be a slide rail and a slide groove structure, which can ensure the guiding stability of the middle frame 14 when it slides.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
