Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to an open-oil electronic cigarette that prevents oil leakage through internal pressure relief. Background Art

[0002] Currently, e-cigarettes typically utilize an interference fit seal between silicone and plastic, or between hardware and plastic—a hard seal—to create a sealed chamber within the e-cigarette, thus preventing leakage. However, the atomizer core's oil inlet is sealed by squeezing a cotton ball against the oil inlet to prevent leakage, a soft seal. This soft seal is often the weakest point, and the tightness of the cotton ball and the size of the oil inlet significantly influence leakage. If the ball is too loose, leakage is likely; if it is too tight, the core will easily become sticky. A too large oil inlet can easily leak, while a too small one can easily cause sticking. Therefore, atomizer core oil leakage is one of the most challenging issues to address in the industry. Summary of the Invention

[0003] The technical problem solved by the present invention is to provide an open-oil electronic cigarette that prevents oil leakage through internal pressure relief; the problem of oil leakage from the atomizer core is solved by using pressure relief silicone and a pressure relief channel.

[0004] The technical solution of the present invention to solve the above technical problems is:

[0005] The electronic cigarette includes an oil tank, an atomization tube, an atomization core, an oil tank sealing silicone and an atomization core bracket; an atomization channel is formed in the center of the oil tank, and the top and the atomization channel are integrated to form a suction nozzle; the bottom of the oil tank is sealed with oil tank sealing silicone; an atomization tube is connected below the atomization channel, an oil inlet hole is provided on the atomization tube, and an atomization core is provided inside; the atomization core bracket is supported at the bottom end of the atomization tube; and it also includes pressure-relief silicone, which is sleeved on the atomization tube and arranged on the inner side of the atomization core bracket; the pressure-relief silicone is provided with a thin film-shaped deformation portion; a deformation space is formed between the pressure-relief silicone and the atomization core bracket, and the atomization core bracket is provided with a pressure-relief channel connected to the outside and the deformation space.

[0006] The upper portion of the pressure-relieving silicone rubber is a disc-shaped portion; a tubular portion is formed downward from the center; the tubular portion is sleeved with the atomizer tube; the oil inlet hole of the atomizer tube is arranged at a position corresponding to the axial direction of the disc-shaped portion, and the oil tank sealing silicone rubber, the upper portion of the disc-shaped portion, and the oil inlet hole form an oil inlet channel from the inside of the oil tank to the atomizer core.

[0007] The disc-shaped portion of the pressure-relieving silica gel forms an oil storage space; the side wall and the bottom of the disc-shaped portion are film-shaped deformation portions.

[0008] The pressure relief channel of the atomizer core bracket is an axially arranged air relief hole; two air relief holes are arranged in the circumferential direction.

[0009] A base is provided below the atomizing core bracket; a magnet receiving hole connected to the air leakage hole is provided on the base corresponding to the air leakage hole; a magnet connected to the rest of the electronic cigarette by magnetic attraction is provided in the magnet receiving hole; a gap is left between the magnet and the magnet receiving hole.

[0010] The inner wall of the magnet receiving hole protrudes a bone position; the magnet receiving hole is interference-fitted with the magnet through the bone position, and a gap is formed between the outer wall of the magnet and the inner wall of the magnet receiving hole.

[0011] The present invention improves the "blocking" in the conventional oil sealing of electronic cigarettes to rely on releasing the internal "pressure" to reduce the pressure difference of the atomizer core oil inlet during high-temperature transportation and high-altitude negative pressure. The present invention sets a fixed deformation space between the pressure-relief silicone and the plastic part (atomizer core bracket); at high temperatures, the internal expansion pressure will become larger, and a pressure relief channel is set to be directly connected to the outside world, reducing the pressure of the internal oil pressure on the atomizer core oil inlet, so as to reduce the risk of oil leakage. When the air is under negative pressure at high altitude, due to the possible insufficient sealing of the silicone plug of the suction nozzle or the silicone plug at the bottom, the air in the main airway will be slowly drawn away, thereby drawing the oil out of the atomizer core oil inlet and causing oil leakage. At this time, the pressure relief channel of the present invention is also in a negative pressure state, causing the pressure relief silicone to deform, reducing the pressure difference of the atomizer core oil inlet, and reducing the risk of oil leakage.

[0020] The following embodiments are descriptions of specific implementation methods of the present invention. Such descriptions are intended to facilitate understanding of the technical solutions of the present application by those skilled in the art and are not intended to limit the scope of protection of the technical solutions of the present invention. Any equivalent transformations that can be obtained based on the description of the embodiments of the present invention should fall within the scope of protection of the present invention.

[0021] like Figure 1-7 As shown, the electronic cigarette of the present invention includes an oil tank 1, an atomizer tube 2, an atomizer core 3, an oil tank sealing silicone 4, an atomizer core support 5, and a pressure relief silicone 6. An atomizer channel 11 is formed in the center of the oil tank 1, and a nozzle 12 is formed integrally with the atomizer channel at the top. The oil tank 1 is sealed with the oil tank sealing silicone 4 at the bottom. The atomizer tube 2 is connected to the bottom of the atomizer channel 11, and the atomizer core 3 is located inside the atomizer tube 2. The atomizer core support 5 is supported at the bottom end of the atomizer tube 2.

[0022] The pressure-relieving silicone rubber 6 has a disc-shaped upper portion 61. A tubular portion 62 extends downward from the center of the disc-shaped portion 61. The tubular portion 62 is connected to the atomizer tube 2. The oil inlet 21 of the atomizer tube 2 is located axially corresponding to the disc-shaped portion 61. The oil reservoir sealing silicone 4, the upper portion of the disc-shaped portion 61, and the oil inlet 21 form an oil inlet passage from the interior of the oil reservoir 1 to the atomizer core 3. The disc-shaped portion 61 forms an oil storage space. The sidewalls and bottom of the disc-shaped portion 61 are thin-film-like deformable portions 63.

[0023] Pressure-relieving silicone rubber 6 is also located inside the atomizer core holder 5. A deformation space 7 is formed between the deformed portion 63 of the pressure-relieving silicone rubber 6 and the atomizer core holder 5. The atomizer core holder 5 is provided with air vents 51 that connect to the exterior and the deformation space 7. These air vents 51 form a pressure relief channel. To ensure balanced air release, two air vents 51 are arranged circumferentially.

[0024] A base 8 is provided below the atomizer core bracket 5. A magnet receiving hole 81 is provided on the base 8 corresponding to the air leakage hole 51 and connected to the air leakage hole 51. A protruding bone portion 82 is provided on the inner wall of the magnet receiving hole 81. The magnet receiving hole 81 is interference-fitted with the magnet 9 via the bone portion 82, and a gap is formed between the outer wall of the magnet 9 and the inner wall of the magnet receiving hole 81.

[0025] At high temperatures, internal expansion pressure increases, causing the deformed portion 63 of the air-releasing silicone 6 to expand and deform toward the atomizer core support 5, compressing the deformation space 7. Air within the deformation space 7 can be discharged to the outside through the air-releasing hole 51 and the magnet-receiving hole 81, thereby maintaining internal pressure balance. Under negative pressure at high altitudes, the deformed portion 63 contracts, expanding the deformation space 7. External air can flow into the deformation space 7 through the magnet-receiving hole 81 and the air-releasing hole 51, thus maintaining pressure balance. Therefore, regardless of air pressure fluctuations, the air pressure on both sides of the oil inlet 51 of the atomizer core 5 remains balanced, preventing oil leakage.

[0026] The structure of the remaining parts of the electronic cigarette of the present invention is shown in the figure. The connection and coordination thereof are irrelevant to the implementation of the aforementioned solution and will not be described in detail here.
