[0002] An e-cigarette is an electronic device that simulates a traditional cigarette. It heats a liquid containing nicotine to produce an aerosol for the user to inhale. The atomizer is one of the core components of an e-cigarette. It stores the e-liquid and has an atomizing core for converting the e-liquid into aerosol.

[0003] Generally speaking, the atomizer core includes oil-guiding cotton and a heating element. The oil-guiding cotton is attached to the heating element, and the oil-guiding cotton and the liquid storage tank are connected to absorb the liquid in the oil-guiding tank. In addition, the atomizer core also plays a certain degree of sealing role in oil leakage in the liquid storage tank, thereby avoiding or reducing oil leakage in the liquid storage tank.

[0004] However, the structure of the existing atomizer only opens a connecting hole between the liquid storage tank and the oil-guiding cotton to achieve oil conduction.

The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] The existing atomizer structure only has a connecting hole between the liquid storage tank and the oil-guiding cotton to achieve oil guidance. This structure makes it difficult for external air to flow into the liquid storage tank when the liquid storage tank supplies oil to the oil-guiding cotton, thereby limiting the speed at which the liquid storage tank guides oil to the oil-guiding cotton. At this time, the oil-guiding cotton is prone to burn due to insufficient oil absorption, which reduces the user experience.

[0044] To address the above issues, embodiments of the present application provide an atomizer, and other embodiments also provide an electronic cigarette including the atomizer. The atomizer helps improve the smoothness of external air entering the liquid storage tank during operation and reduces the phenomenon of oil guide cotton burning.

[0045] refer to Figure 1-3 The atomizer includes a liquid storage tank 1 and an atomizer core 2. The liquid storage tank 1 has a liquid storage tank 111; the atomizer core 2 is disposed in the liquid storage tank 1, and the atomizer core 2 includes a heating element 21 and an oil-conducting cotton 22 attached to the heating element 21. The liquid storage tank 111 is connected to the oil-conducting cotton 22 to achieve oil supply. The atomizer also includes a ventilation channel 3, at least part of the sidewall of the ventilation channel 3 is formed by the oil-conducting cotton 22, the ventilation channel 3 is connected to the liquid storage tank 111, and the ventilation channel 3 has an extended end extending toward the edge of the oil-conducting cotton 22. The extended end is flush with the edge of the oil-conducting cotton 22 or extends beyond the edge of the oil-conducting cotton 22.

[0046] Compared to existing atomizers, the atomizer of the present embodiment further includes a ventilation channel 3, at least a portion of whose sidewalls are formed by oil-conducting cotton 22. The ventilation channel 3 communicates with the liquid reservoir 111 and has an extended end extending from the edge of the oil-conducting cotton 22. The extended end is flush with the edge of the oil-conducting cotton 22 or extends beyond the edge of the oil-conducting cotton 22. When the atomizer is not in operation, tobacco liquid enters the ventilation channel 3 and is absorbed by the oil-conducting cotton 22 to suppress oil leakage from the ventilation channel 3. At this time, the oil-conducting cotton 22 is saturated with tobacco liquid. When the atomizer is in operation, the tobacco liquid in the oil-conducting cotton 22 is consumed and converted into aerosol. At this time, the tobacco liquid in the oil-conducting cotton 22 becomes unsaturated, reducing the amount of tobacco liquid in the ventilation channel 3. This allows the ventilation channel 3 to flow smoothly, allowing external air to enter the liquid reservoir 1 more smoothly through the ventilation channel 3. Subsequently, the tobacco liquid in the liquid reservoir 111 is replenished by the oil-conducting cotton 22. This structural design allows external air to enter the liquid storage tank 1 more smoothly through the ventilation channel 3, which can make the smoke oil in the liquid storage tank 1 more smoothly and quickly replenished to the oil guide cotton 22, which is beneficial to reduce the phenomenon of the oil guide cotton 22 burning due to insufficient smoke oil.

[0047] In some embodiments, reference Figure 1-3 The atomizer core 2 also includes an atomizer sleeve 23, which houses the heater 21 and the oil-guiding cotton 22. The atomizer sleeve 23 has an oil inlet 231, which connects the liquid reservoir 111 to the oil-guiding cotton 22 to ensure oil supply, thereby ensuring that the oil in the liquid reservoir 111 can be replenished to the oil-guiding cotton 22. The atomizer sleeve 23 also serves to secure the heater 21, making the structure more reliable.

[0048] More specifically, refer to Figure 1-3In some embodiments, the liquid storage tank 1 includes a housing body 11 and a sealing plug 12. The housing body 11 defines a liquid reservoir 111, one end of which is open. The atomizer core 2 is mounted on the sealing plug 12. The sealing plug 12 and the atomizer core 2 together seal the opening and, in conjunction with the housing body 11, enclose a liquid storage chamber. The liquid storage chamber can be a sealed chamber connected only to the oil-deflecting cotton 22, thereby reducing oil leakage.

[0049] More specifically, the sealing plug 12 and the atomizer core 2 jointly seal the opening. The atomizer further includes a sealing gasket 4, which is sandwiched between the atomizer core 2 and the opening to further improve the sealing performance and reduce oil leakage.

[0050] In some embodiments, reference Figure 4-6 The ventilation channel 3 is S-shaped, L-shaped, or other shapes. Different shapes of the ventilation channel 3 affect the speed at which external air enters the liquid storage tank 111. For example, if it is S-shaped, the S-shaped shape can store more smoke oil. Only when the oil-guiding cotton 22 is relatively low in smoke oil can it completely absorb the smoke oil inside the S-shaped shape, that is, the ventilation channel 3 is fully open at this time. If it is L-shaped, the stroke is relatively short and the amount of smoke oil stored is small. Therefore, the ventilation channel 3 can be opened when the oil-guiding cotton 22 is slightly saturated, so the smoke oil in the oil storage tank can be replenished to the oil-guiding cotton 22 more promptly.

[0051] In some embodiments, reference Figure 1-3 The shell body 11 is provided with a first air channel 112, which is connected to the oil-conducting cotton 22. The sealing plug 12 is provided with a second air channel 121, which is connected to the oil-conducting cotton 22. Then, the first air channel 112, the oil-conducting cotton 22, and the second air channel 121 form a gas channel connected in series for external air to pass through.

[0052] The ventilation channel 3 , which can improve the smoothness of external air entering the liquid storage tank 1 during operation and reduce the burning of the oil-conducting cotton 22 , will be described in detail below.

[0053] In some embodiments, reference Figure 1 、 Figure 3-6The atomizing sleeve 23 includes an inner side wall that is close to the oil-guiding cotton 22. A slit through hole 232 is opened on the inner side wall of the atomizing sleeve 23. The inner wall of the liquid storage tank 1 blocks the slit through hole 232 on the side facing away from the oil-guiding cotton 22 to enclose a slit groove. One end of the slit groove is connected to the liquid storage tank 111 through the oil inlet hole 231, and the other end of the slit groove extends to the edge of the oil-guiding cotton 22 to form an extended end. The oil-guiding cotton 22 covers the slit groove to enclose a ventilation channel 3. The atomizer sleeve 23 is provided with a slit through hole 232 on the inner wall thereof, and the inner wall of the liquid storage tank 1 is used to block the side of the slit through hole 232 facing away from the oil-guiding cotton 22 to enclose a slit groove, and then the oil-guiding cotton 22 covers the slit groove to form a ventilation channel 3. When the atomizer is not working, the oil-guiding cotton 22 can absorb the oil and be in a saturated state, and the oil-adsorption of the oil-guiding cotton 22 can suppress oil leakage in the ventilation channel 3. When the atomizer is working, external air can smoothly enter the liquid storage tank 1, so that the oil in the liquid storage tank 1 can be quickly replenished to the oil-guiding cotton 22, reducing the phenomenon of the oil-guiding cotton 22 burning.

[0054] More specifically, the inner wall of the liquid storage tank 1 is used to seal the side of the slotted through hole 232 facing away from the oil-conducting cotton 22 to enclose the slotted groove, and the liquid storage tank 1 may include a shell body 11 and a sealing plug 12. Figure 1 、 Figure 3-5 The shell body 11 defines a liquid reservoir 111, one end of which is open. The atomizer core 2 is mounted on a sealing plug 12. The sealing plug 12 and the atomizer core 2 together seal the opening and, in conjunction with the shell body 11, enclose a liquid reservoir. The sealing plug 12 includes a matching portion 122, which blocks the side of the slit through-hole 232 facing away from the oil-conducting cotton 22, thereby enclosing a slit groove. The matching portion 122 can be a raised convex wall on the sealing plug 12, which tightly abuts against the location of the slit groove on the atomizer sleeve 23, thereby enclosing the slit groove.

[0055] Of course, in some embodiments, other methods are also possible. For example, the atomizer sleeve 23 includes an inner side wall that is in close contact with the oil-guiding cotton 22, and the inner side wall of the atomizer sleeve 23 is provided with a slit through hole 232. The slit through hole 232 includes a first slit segment and a second slit segment that are sequentially connected. The first slit segment is connected to the liquid storage tank 111, and the second slit segment extends to the edge of the oil-guiding cotton 22 to form an extended end. The inner wall of the liquid storage tank 1 blocks the side of the second slit segment facing away from the oil-guiding cotton 22 to enclose a slit groove. The oil-guiding cotton 22 covers the second slit segment to enclose the ventilation channel 3. When the atomizer is not working, the oil-guiding cotton 22 absorbs the smoke oil and is in a saturated state, and the adsorption of the oil-guiding cotton 22 suppresses oil leakage in the ventilation channel 3.

[0056] When the atomizer is operating, external air can smoothly enter the liquid reservoir 1, allowing the e-liquid in the reservoir 1 to be quickly replenished to the oil-conducting cotton 22, reducing the risk of the oil-conducting cotton 22 burning. The slit through-hole 232 includes a first slit segment and a second slit segment, which are connected in sequence. The first slit segment is connected to the liquid reservoir 111, thereby preventing the first slit segment from being connected to the oil-conducting hole. This allows for greater flexibility in the design, shape, and layout of the slit through-hole 232. Similarly, the inner wall of the liquid reservoir 1 can also block the side of the second slit segment facing away from the oil-conducting cotton 22 to enclose a slit groove, which can also be implemented as described above and will not be further described.

[0057] Of course, in some embodiments, there may be other ways. For example, the atomizer sleeve 23 includes an inner wall that is close to the oil-conducting cotton 22, and a ventilation groove is provided on the inner wall of the atomizer sleeve 23. One end of the ventilation groove is connected to the liquid storage tank 111 through the oil inlet hole 231, and the other end of the ventilation groove extends to the edge of the oil-conducting cotton 22 to form an extended end. The oil-conducting cotton 22 covers the ventilation groove to enclose a ventilation channel 3. The ventilation groove is provided on the inner wall of the atomizer sleeve 23 to cooperate with the oil-conducting cotton 22 to form a ventilation channel 3, so that when the atomizer is not working, the oil-conducting cotton 22 absorbs the smoke oil and is in a saturated state, and the adsorption of the oil-conducting cotton 22 suppresses oil leakage in the ventilation channel 3; when the atomizer is working, external air can smoothly enter the liquid storage tank 1, so that the smoke oil in the liquid storage tank 1 can be quickly replenished to the oil-conducting cotton 22, reducing the phenomenon of the oil-conducting cotton 22 burning.

[0058] Of course, in some embodiments, there may be other ways. For example, the oil-guiding cotton 22 includes an outer wall that is close to the atomizing sleeve 23, and a ventilation groove is opened on the outer wall of the oil-guiding cotton 22. One end of the ventilation groove is connected to the liquid storage tank 111 through the oil inlet hole 231, and the other end of the ventilation groove extends to the edge of the oil-guiding cotton 22 to form an extended end. The inner wall of the atomizing sleeve 23 and the ventilation groove enclose a ventilation channel 3, so that when the atomizer is not working, the oil-guiding cotton 22 absorbs the oil and is in a saturated state, and the adsorption of the oil-guiding cotton 22 suppresses oil leakage in the ventilation channel 3; when the atomizer is working, the outside air can smoothly enter the liquid storage tank 1, so that the oil in the liquid storage tank 1 can be quickly replenished to the oil-guiding cotton 22, reducing the phenomenon of the oil-guiding cotton 22 burning.

[0059] In addition, for the design of the extension position of the extension end, in some embodiments, reference is made to Figure 5-6The oil-conducting cotton 22 is cylindrical, and its edges include an upper edge 221 and a lower edge 222. The oil-conducting cotton 22 forms an upper edge 221 at one end of its axial direction and a lower edge 222 at the other end. The extended end is flush with the upper edge 221 or extends beyond the upper edge 221; or the extended end is flush with the lower edge 222 or extends beyond the lower edge 222. Preferably, the extended end is flush with the upper edge 221 or extends beyond the upper edge 221. For the atomizer, the upper edge 221 of the oil-guiding cotton 22 is relative to the upper and lower parts of the atomizer. A mouthpiece for the user is generally provided above the atomizer. The upper edge 221 of the oil-guiding cotton 22 is formed at the end of the oil-guiding cotton 22 close to the mouthpiece. The advantage of the extended end being flush with the upper edge 221 or extending out of the upper edge 221 is that the adsorption capacity of the oil-guiding cotton 22 is combined to make the ventilation channel 3 less likely to be blocked, thereby preventing the oil-guiding cotton 22 from blocking the ventilation channel 3 and affecting the air conduction effect of the ventilation channel 3.

[0060] Finally, it should be noted that the various technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various 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.

[0061] The above embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
