Description

Technical Field

[0002] Electronic cigarettes are electronic products that imitate cigarettes, with the same appearance, smoke, taste and feel as cigarettes. They are products that turn nicotine and other substances into vapor through atomization and other means, and then allow users to inhale them. Generally, electronic cigarettes include an atomizer and an electronic cigarette rod, wherein the atomizer mainly includes an oil storage chamber for holding the oil, an atomization core tube assembly for atomizing the oil, and a mouthpiece assembly. The smoke formed by the oil in the atomization core tube is inhaled by the smoker through the mouthpiece assembly.

[0003] However, when the electronic cigarette is transported over long distances or is not used for a long time, the oil outlet of the oil storage chamber is always connected to the oil inlet of the atomizer core tube, and the oil in the atomizer core tube is always saturated. Under the influence of factors such as internal and external pressure, the oil in the atomizer core tube will overflow from the mouthpiece or the air inlet of the atomizer core tube to the outside of the electronic cigarette, causing oil leakage of the electronic cigarette or serious deterioration of the taste, affecting the consumer's experience.

[0035] See also Figures 1 to 5 The oil core separation and anti-leakage structure of the electronic cigarette shown in an embodiment of the utility model can realize the oil core separation when the electronic cigarette is not in use, so that the smoke oil and the atomization core are independently separated before use, avoiding the problems of oil leakage, core sticking, smoke oil taste change, structural deformation, etc. in the prior art. The structure includes: a rotating atomization core assembly and an oil cup sealing assembly.

[0036] The rotary atomizer core assembly includes a base 11, an atomizer core 12 disposed on the base 11, and a first sealing ring 13 sleeved on the upper end of the atomizer core 12. The atomizer core 12 includes a core cover 121, an atomizer cavity is formed in the core cover 121, an atomizer core bracket 122 is provided in the atomizer cavity, and a heating wire 123 and a multi-layer cotton 124 are provided on the atomizer core bracket 122. A mounting groove for mounting the atomizer core 12 is provided on the base 11, a first sealing gasket 14 is provided between the base 11 and the core cover 121, the first sealing gasket 14 is sleeved on the base 11, the shape of the first sealing gasket 14 is adapted to the lower edge of the mounting groove and the core cover 121, and the first sealing gasket 14 is respectively interference fit with the lower edge of the mounting groove and the core cover 121. The base 11 and the atomizer core 12 are detachably connected, which is convenient for cleaning and replacing the base 11 and the atomizer core 12 for a long time.

[0037] The oil cup sealing assembly includes an oil cup shell 21 sleeved on the atomizer core 12, and a second sealing gasket 22 arranged at the lower section of the oil cup shell 21. The oil cup shell 21 includes an outer shell 211, and an air guide tube 212 arranged at the upper end of the oil cup shell 21 and coaxially arranged with the outer shell 211. The atomization chamber is connected to the air guide tube 212, and an oil filling port is provided at the top of the outer shell 211. The lower section of the inner wall of the oil cup shell 21 is raised to form four columns, and the first sealing gasket 14 is provided with a through cavity adapted to the column, and the column is penetrated in the through cavity. The second sealing gasket 22 is sleeved on the lower end of the atomizer core 12, the first sealing ring 13 is transitionally matched with the inner wall of the air guide tube 212, the second sealing gasket 22 is transitionally matched with the outer wall of the core cover 121, and an oil storage cavity is formed between the first sealing ring 13, the atomizer core 12, the second sealing gasket 22 and the oil cup shell 21.

[0038] The lower end of the core cover 121 is provided with at least one oil inlet hole, and the second sealing gasket 22 is provided with a notch corresponding to the oil inlet hole, and the rotary atomization core assembly can rotate relative to the oil cup sealing assembly. The oil storage chamber is connected to the atomization chamber through the oil inlet hole on the atomization core 12. When the electronic cigarette is not in use, the notch is staggered with the oil inlet hole, and the second sealing gasket 22 covers and seals the oil inlet hole. The smoke oil in the oil storage chamber cannot enter the atomization chamber, and the oil core is separated, which effectively avoids oil leakage. The smoke oil will not contact the heating wire 123, and long-term placement will not affect the life of the heating wire 123 and the taste of the smoke oil. When using the electronic cigarette, the consumer only needs to rotate the rotary atomization core assembly so that the oil inlet hole is opposite to the notch on the second sealing gasket 22, the oil storage chamber is connected to the atomization chamber, and the smoke oil flows from the oil storage chamber into the atomization chamber. The heating wire 123 absorbs the smoke oil, and is atomized and then sucked out by the user.

[0039] In this embodiment, there are four oil inlet holes and four notches, and the four oil inlet holes are equidistantly arranged along the circumference of the atomizer core 12, which can ensure that the oil has a higher flow rate when using the electronic cigarette and improve the user experience. In other embodiments, the oil inlet holes and the notches can be arranged as needed. One, two, three, five, etc., are not specifically limited.

[0040] As described above, the first sealing ring 13 is interference-fitted with the outer wall of the core cover 121, and transitionally fits with the inner wall of the air guide tube 212. The second sealing gasket 22 is transitionally fitted with the outer wall of the core cover 121, and forms four columns with the protrusion of the lower section of the inner wall of the oil cup shell 21. The second sealing gasket 22 is provided with a through cavity adapted to the column, and a stainless steel gasket 221 embedded in the second sealing gasket 22. The column is penetrated in the through cavity, so that when the atomizer core 12 rotates relative to the oil cup shell 21, the second sealing gasket 22 and the first sealing ring 13 will not block the rotation process, and there will be no structural deformation caused by the separation of the oil core; at the same time, the first sealing ring 13 and the core cover 121 remain relatively fixed, and relative sliding or even sliding will not occur. The second sealing gasket 22 and the oil cup shell 21 remain relatively fixed, and relative sliding or even sliding will not occur. In the case of long-term use, a good sealing effect can still be maintained.

[0041] The oil cup shell 21 includes a first half shell and a second half shell that is clamped with the first half shell. The first half shell, the base 11 and the second half shell are clamped together to realize the assembly of the oil cup sealing assembly and the rotating atomizer core 12. A limit block is provided on the base 11, and a limit groove adapted to the limit block is provided at the lower end of the oil cup shell 21. The limit block rotates in the limit groove with the atomizer core assembly, and the limit groove is an arc groove of 45°~50°. The limit groove limits the rotation stroke of the limit block, and further limits the rotation stroke of the atomizer core assembly, which greatly reduces the difficulty of the user to open or seal the oil inlet hole by rotating the base 11 when using the electronic cigarette or after using the electronic cigarette, avoiding the situation that it takes a long time to fine-tune the gap to align the oil inlet hole, and effectively prevents the oil leakage caused by the poor sealing of the oil inlet hole after use. As described above, the first sealing gasket 14 is respectively interference-fitted with the mounting groove and the lower edge of the core cover 121 , which can ensure that when the base 11 is manually rotated, the base 11 and the atomizer core 12 remain relatively fixed and do not slide relative to each other.

[0042] Furthermore, the oil cup sealing assembly also includes a suction nozzle 24 disposed on the outer shell 211 and detachably connected to the outer shell 211, the upper end of the air tube 212 extends outside the outer shell 211, the suction nozzle 24 is connected to the air tube 212, the atomization chamber is connected to the suction nozzle 24 through the air tube 212, and a second sealing ring 23 is provided between the suction nozzle 24 and the outer shell 211, the lower surface of the second sealing ring 23 is in contact with the oil filling port and seals the oil filling port, and the second sealing ring 23 is sleeved on the air tube 212 and transitionally matched with the air tube 212. After the smoke oil in the oil storage chamber is consumed, the suction nozzle 24 and the second sealing ring 23 are removed, and the smoke oil is added to the oil storage chamber through the oil filling port. After the filling is completed, the oil filling port is sealed by the suction nozzle 24 and the second sealing ring 23 to prevent oil leakage.

[0043] Preferably, the lower end of the outer wall of the oil cup shell 21 and the cigarette rod of the electronic cigarette are designed with an oblique opening, so that the oil cup shell 21 and the cigarette rod can only be assembled in a fixed direction.

[0044] Furthermore, an electrode 111 is provided on the base 11, and the electrode 111 is arranged correspondingly to the spring pin on the cigarette rod. When the rotating atomizer core assembly rotates relative to the oil cup sealing assembly, the electrode 111 rotates synchronously with the base 11. When the rotating atomizer core assembly rotates relative to the oil cup sealing assembly until the oil inlet hole is directly opposite to the notch, the electrode 111 abuts against the spring pin, and the battery in the cigarette rod supplies power to the heating wire 123; when the rotating atomizer core assembly rotates relative to the oil cup sealing assembly until the oil inlet hole and the notch are offset, the electrode 111 and the spring pin are offset, preventing the user from accidentally drawing the device when the battery is separated, causing the heating wire 123 to dry burn.

[0045] In this embodiment, the oil cup shell 21, the suction nozzle 24, the core cover 121 and the base 11 are all made of stainless steel, the second sealing gasket 22 and the first sealing gasket 14 are both silicone sealing gaskets, and the first sealing ring 13 and the second sealing ring 23 are both silicone sealing rings, which will not be oxidized and corroded during long-term use, thereby effectively improving the service life of the electronic cigarette.

[0046] In summary, the utility model obtains an oil-core separation and oil leakage prevention structure by arranging a relatively rotatable rotating atomization core assembly and an oil cup sealing assembly. The oil storage chamber and the atomization chamber are connected through the oil inlet hole on the atomization core. The oil inlet hole is covered and sealed by a second sealing gasket with a notch, so that the oil core is separated when the electronic cigarette is not in use, and oil leakage is effectively avoided. The tobacco oil will not contact the heating wire, and long-term storage will not affect the life of the heating wire and the taste of the tobacco oil. When the consumer uses the electronic cigarette, he only needs to rotate the rotating atomization core assembly so that the oil inlet hole is opposite to the notch on the second sealing gasket, the oil storage chamber is connected with the atomization chamber, the tobacco oil flows from the oil storage chamber into the atomization chamber, the heating wire absorbs the tobacco oil, and is sucked out by the user after atomization. Through the oil-core separation and oil leakage prevention structure of this scheme, the tobacco oil and the atomization core are independently separated before use, avoiding the problems of oil leakage, core sticking, tobacco oil taste change, structural deformation, etc. in the prior art.

[0047] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
