Description

Technical Field

[0001] This invention relates to the field of lighter technology, and in particular to an ultra-thin, flat flame ignition system. Background Technology

[0002] Currently, direct-fire lighters on the market generally produce single-flame, double-flame, triple-flame (arranged in a straight line), or quadruple-flame (arranged in two rows). Single-flame direct-fire lighters are the most common, but their flame area is relatively small, making it difficult to quickly ignite larger diameter items such as cigars. To overcome this shortcoming, double-flame and triple-flame direct-fire lighters are used to increase the number of ignition points, allowing for rapid ignition of cigars through multi-point combustion. However, these multi-flame direct-fire lighters consume gas too quickly, requiring frequent refills, which is inconvenient and wasteful. Furthermore, these lighters are thick, bulky, difficult to carry, and unattractive. Summary of the Invention

[0003] The purpose of this invention is to provide an ultra-thin, focused, flat flame ignition system. By setting the inner hole of the ceramic cup into a waist-shaped and conical shape, the flame can be flattened and focused, resulting in a linear, flat flame and increasing the flame area. By replacing the existing multiple ignition methods with surface ignition, the system can further improve the performance of tobacco with a larger diameter and significantly reduce gas consumption and waste.

[0004] The ejected gas can be pressurized by using mesh, copper ring and silver sheet, so that the flame is a rush flame and has a windproof function;

[0005] Lighters using this ignition system can be made ultra-thin, making them easier to carry and improving their aesthetics.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0007] An ultra-thin, flat-flame ignition system includes an outlet valve needle, which is inserted into a tower tube cap. The tower tube cap is inserted into and fixed to the lower end of the tower tube. The upper end of the tower tube is screwed to the bottom of the tower head. The tower head extends into the upper shell of the ceramic cup. The upper shell of the ceramic cup is inserted into the lower cover of the ceramic cup. The lower cover of the ceramic cup is clamped between the tower tube and the tower head.

[0008] The tower head has an air outlet channel with an opening on the lower side, and the upper end of the tower head has a cone with multiple radially arranged air outlet holes. The inner end of the air outlet hole communicates with the air outlet channel.

[0009] The upper shell of the porcelain cup is flat, and the interior of the upper shell of the porcelain cup is formed with a waist-shaped flat hole. The two sides of the waist-shaped flat hole are inclined inward to form an inward "eight" shape.

[0010] An ignition hole is formed on one side of the curved wall of the waist-shaped flat hole. One end of an ignition wire is sleeved inside the ignition hole, and the other end of the ignition wire is electrically connected to the piezoelectric element.

[0011] Through the above technical solution, the gas enters the pressure cap of the tower tube through the gas outlet valve needle, and then the gas is transported through the tower tube to the gas outlet duct of the tower head. The gas in the gas outlet duct is ejected outward through multiple gas outlet holes into the upper shell of the ceramic cup. The piezoelectric element generates high voltage by pressing, and ignites the gas in the upper shell of the ceramic cup through the ignition wire. Because the waist-shaped flat hole of the upper shell of the ceramic cup is flat, the flame output of the upper shell of the ceramic cup is also flat, which facilitates the ignition of large-area cigarettes such as cigars and can significantly reduce the ignition time.

[0012] At the same time, because the two sides of the waist-shaped flat hole are inclined inward, the fire inside the upper shell of the porcelain cup can be further concentrated inward, increasing the "density" of the emitted fire, thereby further improving the ignition effect.

[0013] The present invention is further configured such that: the lower cover of the porcelain cup is a stepped waist-shaped block with a smaller upper part and a larger lower part; the bottom of the upper shell of the porcelain cup is formed with a waist-shaped hole, the upper part of the lower cover of the porcelain cup is inserted into the waist-shaped hole, and the stepped surface of the lower cover of the porcelain cup abuts against the bottom surface of the upper shell of the porcelain cup.

[0014] The lower cover of the ceramic cup has a tower head mounting hole formed in the middle, which matches the tower head. The lower protruding end of the tower head, which passes through the tower head mounting hole, is screwed to the upper end of the tower tube.

[0015] The upper end of the tower head is formed with a waist-shaped shoulder, which is located below the air outlet and abuts against the upper surface of the ceramic cup cover; the straight part of the waist-shaped shoulder presses against the straight surface of the waist-shaped flat hole.

[0016] Through the above technical solution, the tower tube, tower head, tower tube cap and ceramic cup lower cover can be fastened into one piece by the screw connection between the tower head and the tower tube; while the ceramic cup upper shell and ceramic cup lower cover are connected by plug-in method, which can adapt to the thermal expansion and contraction of the ceramic cup; the fit between the waist-shaped shoulder and the waist-shaped flat hole can prevent the ceramic cup upper shell from rotating freely.

[0017] The present invention is further configured such that: the tower tube is formed with an upper vent hole, a lower assembly hole and an intermediate vent hole connecting the upper vent hole and the lower assembly hole; and an air inlet communicating with the upper vent hole is formed on the outer wall of the tower tube.

[0018] The tower tube cap is inserted into the lower assembly hole, and the upper end of the tower tube cap is interference-fitted with the lower assembly hole.

[0019] The lower assembly hole is provided with a silver sheet, a copper ring and a mesh in sequence from top to bottom; the silver sheet, copper ring and mesh are tightly clamped between the top of the tower tube cap and the bottom surface of the lower assembly hole;

[0020] The inner part of the tower tube compression cap is formed with a stepped air outlet hole that is smaller at the top and larger at the bottom. The outer diameter of the air outlet valve needle is set with a clearance fit with the large end hole of the stepped air outlet hole. At least two sealing rings are sleeved on the air outlet valve needle up and down, and the sealing rings are pressed against the inner wall of the stepped air outlet hole.

[0021] A small hole is formed in the middle of the silver sheet, and the aperture of the small hole is ≤ 0.07 mm.

[0022] The inner diameter of the copper ring is much larger than the aperture of the small hole.

[0023] Through the above technical solutions, the sealing ring can facilitate the axial movement of the air outlet valve needle in the tower tube compression cap and prevent the leakage of gas. The mesh sheet can filter the gas coming out of the air outlet valve needle to prevent the silver sheet from being blocked. The filtered gas is sprayed out from the small hole of the silver sheet through the copper ring. Since the small hole of the silver sheet is much smaller than the inner diameter of the copper ring, the sprayed gas can be further pressurized, so that the gas pressure of the gas sprayed upward from the small hole of the silver sheet is greater. At the same time, air enters through the air inlet and mixes with the gas in the upper ventilation hole. The pressurized gas then sprays out from the tower head through the tower tube in sequence. Since the pressure of the sprayed gas mixture is relatively large, the fire sprayed out from the upper shell of the porcelain cup has a certain pressure, that is, impact fire, which can play a role in preventing wind and further improve the ignition effect of the fire sprayed out from the porcelain cup.

[0024] The present invention is further set as follows: the width W of the waist-shaped flat hole is ≤ 3 mm.

[0025] Through the above technical solutions, the maximum thickness of the fire in the upper shell of the porcelain cup is 3 mm, which can greatly reduce the overall thickness of the ignition system, so that the lighter using this ignition system in the later stage can be thinner.

[0026] An ultra-thin lighter includes the above ultra-thin fire-gathering flat-fire ignition system.

[0027] An ultra-thin lighter further includes a main shell, a gas storage part, a main base, a pressing part, a flip part and a valve pry plate.

[0028] The air outlet valve is connected inside the gas storage part, and the gas storage part is inserted and fixed inside the main shell. The main base is inserted and fixed at the upper end of the main shell. The flip part is rotatably connected to the main base, and the flip part can be flipped to cover the upper half of the main base. The pressing part is slidably connected to the main base. The lower end of the pressing part is pressed against the piezoelectric element, and the piezoelectric element is inserted into the card slot on the gas storage part.

[0029] A waist-shaped cavity is formed on the main base, and an inward flange is formed at the upper port of the waist-shaped cavity. The upper shell of the porcelain cup is inserted into the waist-shaped cavity and the upper end of the upper shell of the porcelain cup abuts against the inward flange. The tower tube is inserted into the support seat, and the lower end of the lower cover of the porcelain cup abuts against the support seat. The support seat is inserted into the "C"-shaped protrusion of the gas storage part.

[0030] With the above technical solution, the entire ignition system can be supported by the support base, while the upper shell of the ceramic cup is clamped between the main base and the lower cover of the ceramic cup, thereby securing the entire ignition system between the main base and the gas storage section.

[0031] The present invention is further configured such that: the valve skid is formed with a small U-shaped groove and a large U-shaped groove, the small U-shaped groove is inserted into the outlet valve needle and located below the stepped surface of the outlet valve needle; the large U-shaped groove is inserted into the rectangular platform of the air storage section; and the end of the valve skid near the outlet valve needle abuts against the arc top of the air storage section.

[0032] The end of the valve skid away from the outlet valve needle is located below the pressing plate of the pressing part.

[0033] When the lighter needs to be used, press down on the pressing part. The pressing part moves down and presses down the end of the valve lever away from the outlet valve needle. The end of the valve lever near the outlet valve needle pries the outlet valve needle upward, thereby opening the outlet valve. The gas in the gas storage compartment enters the tower tube pressure cap through the outlet valve and outlet valve needle. After being filtered by the mesh and pressurized by the silver sheet, the gas mixes with air and enters the upper shell of the ceramic cup.

[0034] Then, as the pressing part continues to move downward, the piezoelectric element is pressed by the pressing part to generate high voltage, thereby igniting the gas mixture inside the ceramic cup shell.

[0035] The present invention is further configured such that the outer contours of the front, rear, left, and right sides of the main housing and the flip cover are of the same size;

[0036] The thickness H of the main housing is ≤ 7.5 mm;

[0037] The length of the main shell is L, and the ratio of L to H is between 5:1 and 6:1.

[0038] With the above technical solution, the overall thickness of the lighter is 7.5mm or less, which makes the thickness of this lighter between one-third and one-half of the thickness of existing ordinary lighters; at the same time, by setting a certain length-to-width ratio, this lighter can be more beautiful and more convenient to carry.

[0039] The outstanding effects of this invention are:

[0040] Compared with existing technologies, by setting the inner hole of the ceramic cup into a waist-shaped and conical shape, the flame can be flattened and concentrated, making the flame appear as a linear flat flame and increasing the flame area; by replacing the existing multiple ignition methods with surface ignition, the size of tobacco can be further increased, and the consumption and waste of gas can be significantly reduced.

[0041] The ejected gas can be pressurized by using mesh, copper ring and silver sheet, so that the flame is a rush flame and has a windproof function;

[0042] Lighters using this ignition system can be made ultra-thin, making them easier to carry and improving their aesthetics. Attached Figure Description

[0070] The following combines the accompanying drawings and embodiments to further describe the specific embodiments of the present invention in detail. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0071] The following is a reference<000016所>to illustrate the present invention:

[0072] <00所0169>As shown, an ultra-thin concentrated-fire flat-fire ignition system includes an air outlet valve needle 10 of an air outlet valve. The air outlet valve needle 10 is inserted and sleeved in a tower tube compression cap 20. The tower tube compression cap 20 is inserted and fixed at the lower end of a tower tube 21. The upper end of the tower tube 21 is screwed to the bottom of a tower head 22. The tower head 22 extends into an upper shell 23 of a porcelain cup. The upper shell 23 of the porcelain cup is inserted and sleeved on a lower cover 24 of the porcelain cup. The lower cover 24 of the porcelain cup is clamped between the tower tube 21 and the tower head 22;<000017所>

[0073] The tower head 22 has an air outlet 221 with an opening on the lower side formed inside. The upper end of the tower head 22 has a cone 222 formed. Multiple radially arranged air outlets 223 are formed on the cone 222. The inner end of the air outlet 223 communicates with the air outlet 221.

[0074] The upper shell 23 of the porcelain cup is flat, and the interior of the upper shell 23 of the porcelain cup has a waist-shaped flat hole 231. The two sides of the waist-shaped flat hole 231 have rounded walls 232 that are inclined inward to form an inward "eight".

[0075] An ignition hole 233 is formed on one side of the arc wall 232 of the waist-shaped flat hole 231. One end of the ignition wire 25 is sleeved inside the ignition hole 233, and the other end of the ignition wire 25 is electrically connected to the piezoelectric element 26.

[0076] Gas enters the pressure cap of the tower tube through the outlet valve needle, and then is transported through the tower tube to the outlet duct at the tower head. The gas in the outlet duct is then ejected outwards through multiple outlet holes into the upper shell of the ceramic cup. A piezoelectric element generates high voltage by pressing, which ignites the gas in the upper shell of the ceramic cup via an ignition wire. Because the waist-shaped flat orifice on the upper shell of the ceramic cup is flat, the flame output from the upper shell is also flat, facilitating the ignition of large-area cigarettes such as cigars and significantly reducing ignition time.

[0077] At the same time, because the two sides of the waist-shaped flat hole are inclined inward, the fire inside the upper shell of the porcelain cup can be further concentrated inward, increasing the "density" of the emitted fire, thereby further improving the ignition effect.

[0078] The lower cover 24 of the porcelain cup is a stepped waist-shaped block with a smaller upper part and a larger lower part; the bottom of the upper shell 23 of the porcelain cup is formed with a waist-shaped hole 234, the upper part of the lower cover 24 of the porcelain cup is inserted into the waist-shaped hole 234, and the stepped surface of the lower cover 24 of the porcelain cup abuts against the bottom surface of the upper shell 23 of the porcelain cup.

[0079] The lower cover 24 of the ceramic cup has a tower head mounting hole 241 formed in the middle, which matches the tower head 22. The lower protruding end of the tower head 22 through the tower head mounting hole 241 is screwed to the upper end of the tower tube 21.

[0080] The upper end of the tower head 22 is formed with a waist-shaped shoulder 224, which is located below the air outlet 223 and abuts against the upper surface of the ceramic cup lower cover 24; the straight part of the waist-shaped shoulder 224 presses against the straight surface of the waist-shaped flat hole 231.

[0081] The tower head and tower tube are screwed together to secure the tower tube, tower head, tower tube cap and lower cover of the ceramic cup into one unit; the upper shell of the ceramic cup and the lower cover of the ceramic cup are connected by a plug-in method to accommodate the thermal expansion and contraction of the ceramic cup; the fit between the waist-shaped shoulder and the waist-shaped flat hole prevents the upper shell of the ceramic cup from rotating freely.

[0082] The tower tube 21 is formed with an upper vent 211, a lower assembly hole 212 and an intermediate vent 213 connecting the upper vent 211 and the lower assembly hole 212; an air inlet 214 communicating with the upper vent 211 is formed on the outer wall of the tower tube 21.

[0083] The tower tube cap 20 is inserted into the lower assembly hole 212 and the upper end of the tower tube cap 20 is interference-fitted with the lower assembly hole 212.

[0084] The lower assembly hole 212 is provided with a silver sheet 27, a copper ring 28 and a mesh 29 arranged sequentially from top to bottom; the silver sheet 27, the copper ring 28 and the mesh 29 are tightly clamped between the top of the tower tube cap 20 and the bottom surface of the lower assembly hole 212.

[0085] The tower tube cap 20 has a stepped air outlet 201 with a smaller upper part and a larger lower part inside. The outer diameter of the air outlet valve needle 10 is fitted with the larger end hole of the stepped air outlet 201. At least two sealing rings 11 are fitted on the air outlet valve needle 10, which are arranged vertically and vertically. The sealing rings 11 are pressed against the inner wall of the stepped air outlet 201.

[0086] The silver sheet 27 has a small hole 271 formed in the middle, and the diameter of the small hole 271 is ≤0.07 mm;

[0087] The inner diameter of the copper ring 28 is much larger than the diameter of the small hole 271.

[0088] The sealing ring facilitates the axial movement of the outlet valve needle within the tower tube pressure cap, preventing gas leakage. The mesh filters the gas exiting the outlet valve needle, preventing blockage of the silver plate. The filtered gas is ejected through the copper ring from the small holes in the silver plate. Since the small holes in the silver plate are much smaller than the inner diameter of the copper ring, the ejected gas is further pressurized, resulting in greater pressure of the gas ejected upwards from the small holes in the silver plate. Simultaneously, air enters through the air inlet and mixes with the gas at the upper vent. The pressurized gas then passes through the tower tube and is ejected from the tower head. Due to the high pressure of the ejected gas mixture, the flame ejected from the upper shell of the ceramic cup has a certain pressure, which is called impingement ignition. This serves as a windproof measure and further enhances the ignition effect of the flame ejected from the ceramic cup.

[0089] The width W of the waist-shaped flat hole 231 is ≤ 3 mm.

[0090] By limiting the maximum thickness of the flame inside the ceramic cup shell to 3 mm, the overall thickness of the ignition system can be significantly reduced, allowing lighters using this ignition system to be thinner in the future.

[0091] Figures 10 to 15 As shown, an ultra-thin lighter includes the aforementioned ultra-thin concentrating flat flame ignition system.

[0092] An ultra-thin lighter further includes a main housing 30, a gas storage portion 31, a main base 32, a pressing portion 33, a flip cover portion 34, and a valve prying plate 35;

[0093] The gas outlet valve is connected inside the gas storage portion 31. The gas storage portion 31 is inserted and fixed inside the main housing 30. The main base 32 is inserted and fixed at the upper end of the main housing 30. The flip cover portion 34 is rotatably connected to the main base 32, and the flip cover portion 34 can be flipped to cover the upper half of the main base 32; The pressing portion 33 is slidably connected to the main base 32; The lower end of the pressing portion 33 presses against the piezoelectric element 26, and the piezoelectric element 26 is inserted into the card slot 311 on the gas storage portion 31;

[0094] A waist-shaped cavity 321 is formed on the main base 32, and an inward flange 322 is formed at the upper port of the waist-shaped cavity 321; The upper shell 23 of the porcelain cup is inserted into the waist-shaped cavity 321 and the upper end of the upper shell 23 of the porcelain cup abuts against the inward flange 322; The tower tube 21 is inserted into the support seat 36, and the lower end of the lower cover 24 of the porcelain cup abuts against the support seat 36; The support seat 36 is inserted into the "C"-shaped protrusion 312 of the gas storage portion 31. <0​​​​​​​​​​​​​​​​​​​The thickness H of the main housing 30 is ≤ 7.5 mm;

[0102] The length of the main housing 30 is L, and the ratio of L to H is between 5:1 and 6:1.

[0103] The overall thickness of the lighter is 7.5mm or less, which makes the thickness of this lighter between one-third and one-half of the thickness of existing ordinary lighters; at the same time, by setting a certain length-to-width ratio, this lighter can be more beautiful and more convenient to carry.

[0104] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications assumed above should also be considered within the scope of protection of the present invention.
