The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] The present invention relates to an atomization central air pipe. In one embodiment, the atomization central air pipe includes an atomization pipe and a connecting pipe. The connecting pipe includes a tube body and an oil-blocking sub-tube. The tube body is connected to the atomization pipe and the oil-blocking sub-tube respectively. At least part of the oil-blocking sub-tube is located inside the atomization pipe, the outer wall of the oil-blocking sub-tube is connected to the inner wall of the atomization pipe, and the oil-blocking sub-tube has an air outlet. The air outlet is connected to the interior of the atomization pipe, and the air outlet is arranged away from the inner wall of the atomization pipe to form a blocking portion, which is used to block the chance of condensate being inhaled into the user's mouth during smoking or to block the chance of tobacco oil flowing out of the central air pipe. By adding a fuel blocker tube and moving the air outlet away from the inner wall of the atomizer tube, the side wall of the air outlet is misaligned with the inner wall of the atomizer tube, so that the bottom of the fuel blocker tube protrudes from the inner wall of the atomizer tube, which makes it easier to block the condensation on the inner wall of the atomizer tube and the smoke oil from flowing to the air outlet, thereby reducing the chance of condensation and smoke oil flowing out of the atomizer center air pipe.

[0026] See also Figure 1 , which is a schematic structural diagram of the atomization center air pipe according to one embodiment of the present invention.

[0027] The atomizing central air pipe 200 of one embodiment includes an atomizing pipe 310 and a connecting pipe 210. Figure 2 The connecting tube 210 includes a tube body 212 and an oil-blocking sub-tube 214. The tube body 212 is connected to the atomizing tube 310 and the oil-blocking sub-tube 214, respectively. At least a portion of the oil-blocking sub-tube 214 is located inside the atomizing tube 310, and the outer wall of the oil-blocking sub-tube 214 is connected to the inner wall of the atomizing tube 310. The oil-blocking sub-tube 214 has an air outlet 2142. The air outlet 2142 is in communication with the interior of the atomizing tube 310, and the air outlet 2142 is arranged away from the inner wall of the atomizing tube 310 to form a blocking portion 2148. The blocking portion 2148 is used to prevent at least one of condensate and smoke oil from flowing out of the atomizing center air pipe to the outside of the air outlet.

[0028] Furthermore, the connecting tube 210 includes a tube body 212 and an oil-blocking sub-tube 214. The tube body 212 is connected to the atomizer tube 310 and the oil-blocking sub-tube 214, respectively. At least a portion of the oil-blocking sub-tube 214 is located within the atomizer tube 310, and the outer wall of the oil-blocking sub-tube 214 is connected to the inner wall of the atomizer tube 310. The oil-blocking sub-tube 214 has an air outlet 2142. The air outlet 2142 is in communication with the interior of the atomizer tube 310 and is disposed away from the inner wall of the atomizer tube 310 to form a blocking portion 2148. The blocking portion 2148 is used to prevent condensate from being inhaled into the user's mouth during smoking or to prevent smoke oil from flowing out of the central air pipe.

[0029] In this embodiment, by adding an oil-blocking sub-tube 214 and positioning the air outlet 2142 away from the inner wall of the atomizer tube 310, for example, the air outlet 2142 is located in the middle of the oil-blocking sub-tube 214, and the aperture of the air outlet 2142 is smaller than the diameter of the atomizer tube 310, so that the sidewalls of the air outlet 2142 are misaligned with the inner wall of the atomizer tube 310, thereby causing the bottom of the oil-blocking sub-tube 214 to protrude from the inner wall of the atomizer tube 310, thereby preventing condensate and e-liquid on the inner wall of the atomizer tube 310 from flowing toward the air outlet, thereby reducing the probability of condensate and e-liquid flowing out of the atomizer center air pipe 200. In this embodiment, the tube body 212 and the oil-blocking sub-tube 214 are integrally formed, and the air outlet is connected to both the atomizer tube and the connecting tube, and is used to direct the smoke formed in the atomizer tube to the outside for inhalation by the user. Moreover, the blocking portion is used in two aspects: 1. to prevent the condensed liquid generated by the smoke during smoking from being inhaled into the mouth of the user along the tube wall along with the smoking airflow; 2. to prevent the smoke oil from detaching from the oil-conducting cotton and flowing out along the inner tube wall during transportation.

[0030] In one embodiment, see Figure 2 The connecting tube 210 further includes an oil-blocking protruding tube 216, which is connected to the oil-blocking sub-tube 214. The oil-blocking protruding tube 216 has an air vent 2162, which is aligned with and communicates with the air outlet 2142. In this embodiment, the oil-blocking protruding tube 216 serves as an extension of the oil-blocking sub-tube 214. The oil-blocking protruding tube 216 protrudes from the oil-blocking sub-tube 214, wherein the central axis of the oil-blocking protruding tube 216 is arranged parallel to the central axis of the oil-blocking sub-tube 214. The protruding direction of the oil-blocking protruding tube 216 is opposite to the air guide direction of the air outlet 2142. Therefore, when the atomization center air pipe 200 is inverted or lying flat, the protruding direction of the oil-blocking protruding tube 216 is opposite to the direction of movement of the e-liquid on the inner wall of the atomization tube 310. Moreover, an oil-blocking space is formed between the oil-blocking protruding tube 216, the oil-blocking sub-tube 214 and the atomizer tube 310. The opening direction of the oil-blocking space is opposite to the movement direction of the smoke oil on the inner wall of the atomizer tube 310. The oil-blocking space is used to block the smoke oil therein, so that when the atomizer center air pipe 200 is inverted or lying flat, the movement path of the smoke oil attached to the inner wall of the atomizer tube 310 is blocked by the side wall of the oil-blocking space, so that the smoke oil attached to the inner wall of the atomizer tube 310 is accommodated in the oil-blocking space, thereby reducing the probability of the smoke oil attached to the inner wall of the atomizer tube 310 moving into the air outlet 2142, thereby reducing the probability of the smoke oil overflowing along the inner wall of the atomizer center air pipe 200, and further reducing the probability of oil leakage of the atomizer center air pipe 200.

[0031] In one embodiment, see Figure 2 , the center line of the air outlet 2142 is arranged to coincide with the center line of the atomizing tube 310. In this embodiment, the air outlet 2142 and the atomizing tube 310 are in a connected state, the atomizing tube 310 guides the atomized smoke to the air outlet 2142, and the air outlet 2142 guides the smoke to the outside, that is, the atomizing tube 310 and the connecting tube 210 form an air guide channel, which is convenient for guiding the smoke out. In order to facilitate the smoke to be guided out along with the flow of air, the center line of the air outlet 2142 and the center line of the atomizing tube 310 are set to coincide with each other, which reduces the contact between the smoke and the oil retaining space, thereby reducing the air guide path of the smoke, facilitating the rapid guidance of the smoke to the outside, and improving the smoke export rate, thereby improving the use efficiency of the atomizing center air pipe 200.

[0032] In one embodiment, see Figure 3 A clamping space 218 is formed between the tube body 212 and the oil choke sub-tube 214, and a portion of the atomizer tube 310 is clamped in the clamping space 218. In this embodiment, the clamping space 218 is formed at the connection between the tube body 212 and the oil choke sub-tube 214, that is, the outer wall of the oil choke sub-tube 214 and the bottom of the tube body 212 form the clamping space 218. The clamping space 218 is used to accommodate a portion of the atomizer tube 310. The inner wall of the atomizer tube 310 abuts against the side wall of the clamping space 218, so that the atomizer tube 310 is placed on the oil choke sub-tube 214, that is, the inner wall of the atomizer tube 310 abuts against the outer wall of the oil choke sub-tube 214, and the end of the atomizer tube 310 abuts against the end of the tube body 212. In this way, when the atomizer tube 310 is clamped in the clamping space 218, the connection positions between the atomizer tube 310 and the connecting tube 210 are increased, so that the connection between the atomizer tube 310 and the connecting tube 210 is increased, thereby making the connection between the atomizer tube 310 and the connecting tube 210 more stable, which facilitates improving the connection stability between the atomizer tube 310 and the connecting tube 210.

[0033] Furthermore, there are multiple connecting tubes 210, and two adjacent connecting tubes 210 are mutually engaged through the engaging space 218. In this embodiment, the multiple connecting tubes 210 are connected in sequence, that is, the multiple connecting tubes 210 are connected in series to form a linear pipeline. Moreover, each connecting tube 210 has the engaging space 218, and two adjacent connecting tubes 210 are connected through the engaging space 218, that is, the tube body 212 of one connecting tube 210 is engaged in the engaging space 218 of another connecting tube 210, so that the multiple connecting tubes 210 are mutually engaged in sequence, thereby forming an area between the adjacent two connecting tubes 210 to block the movement of smoke oil, that is, the protruding portion at the bottom of the oil blocking sub-tube 214. This protruding portion is formed by the air outlet 2142 being away from the inner wall of the atomizer tube 310. In this way, there is a smoke oil blocking portion between the atomizing tube 310 and the connecting tube 210, and there is also a smoke oil blocking portion between two adjacent connecting tubes 210, so that the atomizing center air pipe 200 forms multiple structures that block the movement of smoke oil in the air guide direction, thereby making the atomizing center air pipe 200 have a multi-stage smoke oil blocking structure, that is, a multi-stage barrier atomizing center air pipe 200, further reducing the probability of oil leakage of the atomizing center air pipe 200.

[0034] In one embodiment, see Figure 3The outer wall of the oil choke sub-tube 214 has a first mounting bevel 2144, which is inclined toward the atomizer tube 310. The first mounting bevel 2144 is used to be slidably connected to the atomizer tube 310 when the connecting tube 210 is installed. In this embodiment, the oil choke sub-tube 214 is accommodated in the atomizer tube 310, that is, the outer wall of the oil choke sub-tube 214 abuts against the inner wall of the atomizer tube 310, that is, the outer wall of the oil choke sub-tube 214 is clamped on the inner wall of the atomizer tube 310. When the connecting tube 210 is installed on the atomizer tube 310, the oil choke sub-tube 214 serves as the main part that is clamped with the atomizer tube 310. The smooth insertion of the oil choke sub-tube 214 into the atomizer tube 310 affects the overall sealing performance of the atomization center air pipe 200. The first mounting bevel 2144 is located on the outer wall of the oil-blocking sub-tube 214, and the inclination direction of the first mounting bevel 2144 is toward the atomizer tube 310, that is, in the direction perpendicular to the central axis of the atomizer tube 310, the distance between the first mounting bevel 2144 and the inner wall of the atomizer tube 310 gradually decreases, so that an angle is formed between the first mounting bevel 2144 and the inner wall of the atomizer tube 310, so that a gap is formed between the outer wall of the oil-blocking sub-tube 214 and the inner wall of the atomizer tube 310, which facilitates the oil-blocking sub-tube 214 to extend into the atomizer tube 310, that is, the side wall of the atomizer tube 310 slides on the first mounting bevel 2144, thereby facilitating the insertion of the oil-blocking sub-tube 214 into the atomizer tube 310, so that the atomizer tube 310 is sleeved on the oil-blocking sub-tube 214.

[0035] Further, see Figure 3The inner wall of the atomizing tube 310 has a second mounting bevel 314, and the second mounting bevel 314 is arranged parallel to the first mounting bevel 2144. In this embodiment, the oil choke sub-tube 214 is accommodated in the atomizing tube 310, that is, the outer wall of the oil choke sub-tube 214 abuts against the inner wall of the atomizing tube 310, that is, the outer wall of the oil choke sub-tube 214 is clamped on the inner wall of the atomizing tube 310. When the connecting tube 210 is installed on the atomizing tube 310, the oil choke sub-tube 214 serves as the main part that is clamped with the atomizing tube 310. The smooth insertion of the oil choke sub-tube 214 into the atomizing tube 310 affects the overall sealing performance of the atomizing center air pipe 200. The second mounting bevel 314 is located at the end of the atomizer tube 310, and the inclination direction of the second mounting bevel 314 is toward the oil-blocking sub-tube 214, that is, in a direction perpendicular to the central axis of the atomizer tube 310, the distance between the second mounting bevel 314 and the outer wall of the oil-blocking sub-tube 214 gradually decreases, so that an angle is formed between the second mounting bevel 314 and the outer wall of the oil-blocking sub-tube 214, thereby forming a gap between the outer wall of the oil-blocking sub-tube 214 and the inner wall of the atomizer tube 310. In this way, when the second mounting bevel 314 and the first mounting bevel 2144 are parallel to each other, the first mounting bevel 2144 slides along the second mounting bevel 314, making it convenient for the oil-blocking sub-tube 214 to extend into the atomizing tube 310, that is, the second mounting bevel 314 slides relative to the first mounting bevel 2144, that is, the first mounting bevel 2144 is slidably arranged on the second mounting bevel 314, thereby facilitating the insertion of the oil-blocking sub-tube 214 into the atomizing tube 310, thereby improving the smoothness of the connection between the connecting tube 210 and the atomizing tube 310.

[0036] It is understandable that when the atomization center air pipe 200 is in an inverted or flat position for a long time, the smoke oil in the atomization pipe 310 gradually accumulates. Once the accumulated volume of the smoke oil increases to exceed the maximum space volume of the oil blocking space between the oil blocking protrusion tube 216, the oil blocking sub-tube 214 and the atomization pipe 310, the smoke oil will pass over the oil blocking protrusion tube 216 and directly enter the vent 2162, and then flow directly into the air outlet 2142 through the vent 2162, and then directly overflow from the connecting pipe 210, resulting in a decrease in the oil leakage prevention performance of the atomization center air pipe 200, that is, the atomization center air pipe 200 cannot be in an inverted or flat position for a long time, which easily causes the user to directly inhale the smoke oil during use, affecting the user's use.

[0037] In order to further improve the anti-leakage performance of the electronic atomizer, please refer to Figure 4, the vent hole 2162 is aligned with the air outlet 2142, and the aperture of the vent hole 2162 is larger than the aperture of the air outlet 2142. In this embodiment, the air outlet 2142 is provided on the oil-blocking sub-tube 214, and the vent hole 2162 is provided on the oil-blocking protruding tube 216. The oil-blocking sub-tube 214 and the oil-blocking protruding tube 216 are communicated with each other, that is, the oil-blocking sub-tube 214 and the oil-blocking protruding tube 216 are communicated with each other through the air outlet 2142 and the vent hole 2162. That is, when the air outlet 2142 and the vent hole 2162 are communicated with each other, the smoke generated in the atomizing tube 310 passes through the vent hole 2162 and the air outlet 2142, and then passes through the oil-blocking protruding tube 216 and the oil-blocking sub-tube 214. When the vent hole 2162 is aligned with the air outlet 2142, the oil choke sub-tube 214 is arranged parallel to the oil-blocking protruding tube 216, so that the oil choke sub-tube 214 and the oil-blocking protruding tube 216 are connected in a straight line. The diameter of the vent hole 2162 is larger than the diameter of the air outlet 2142, so that the smoke flow hole of the oil choke sub-tube 214 is smaller than the smoke flow hole of the oil-blocking protruding tube 216. As a result, a portion of the oil choke sub-tube 214 corresponds to the vent hole 2162, and the portion of the oil choke sub-tube 214 near the air outlet 2142 blocks a portion of the vent hole 2162. In this way, the shielding portion of the oil-blocking sub-tube 214 close to the air outlet 2142 blocks the smoke oil in the atomization tube 310 within the oil-blocking protruding tube 216, reducing the probability of the smoke oil continuing to overflow into the air outlet 2142, thereby further reducing the oil leakage probability of the atomization center air pipe 200, and further improving the anti-leakage performance of the atomization center air pipe 200.

[0038] Furthermore, in order to facilitate closing the air outlet 2142 when the atomizing central air pipe 200 is inverted or lying flat, so as to improve the oil leakage prevention performance of the atomizing central air pipe 200, please refer to Figure 4The atomizing central air pipe 200 further includes a blocking assembly 220, which includes a blocking plate 222, a rotating shaft 224, and a fixed protrusion 226. The rotating shaft 224 is connected to the outer wall of the oil-blocking sub-tube 214. The blocking plate 222 is rotatably connected to the rotating shaft 224. The blocking plate 222 is used to block the air outlet 2142. The fixed protrusion 226 is located on a side of the blocking plate 222 close to the oil-blocking sub-tube 214. The fixed protrusion 226 is connected to the blocking plate 222. The outer wall of the oil-blocking sub-tube 214 is provided with a fixed groove 2146. The fixed protrusion 226 is used to be locked in the fixed groove 2146. In this embodiment, the blocking plate 222 rotates around the rotating shaft 224 as the central axis and is used to open and close the air outlet 2142. When the atomizing central air pipe 200 is placed upright, the blocking plate 222 moves away from the oil-blocking sub-tube 214 under the action of its own gravity, so that the air outlet 2142 is opened, facilitating the outflow of smoke generated in the atomizing pipe 310 through the air outlet 2142; and when the atomizing central air pipe 200 is inverted or lying flat, the blocking plate 222 is deflected under the action of its own gravity, so that the blocking plate 222 rotates toward the oil-blocking sub-tube 214, thereby blocking the air outlet 2142 and further closing the air outlet 2142. At this time, the smoke oil in the atomizing pipe 310 is blocked outside the connecting pipe 210 by the blocking plate 222, reducing the probability of the smoke oil in the atomizing pipe 310 overflowing through the air outlet 2142 of the connecting pipe 210, and further improving the anti-leakage performance of the atomizing central air pipe 200. When the blocking plate 222 closes the air outlet 2142, the fixing protrusion 226 is received in the fixing groove 2146, so that the blocking plate 222 is stably fixed on the oil choke sub-tube 214, thereby improving the connection stability between the blocking plate 222 and the oil choke sub-tube 214 and facilitating the fixing of the blocking plate 222 to the connecting tube 210. When the atomizing center air pipe 200 returns to the upright position, the blocking plate 222 is detached from the oil choke sub-tube 214 by blowing air into the atomizing center air pipe 200, thereby unblocking the air outlet 2142 and facilitating continued use.

[0039] In another embodiment, in order to facilitate the blocking plate 222 to quickly close the air outlet 2142, the flow of the smoke oil into the air outlet 2142 is reduced, that is, the volume of the smoke oil flowing into the air outlet 2142 is reduced. Figure 4The blocking assembly 220 further includes a bevel block 228 , which is connected to the outer wall of the oil-blocking sub-tube 214 . The bevel block 228 has an inclined surface 2282 , which is inclined toward the blocking plate 222 , and the blocking plate 222 abuts against the inclined surface 2282 . In this embodiment, the inclined surface 2282 forms an included angle with the outer wall of the oil-blocking sub-tube 214, and the inclined surface 2282 is inclined toward the direction close to the air outlet 2142, so that the partial projection of the inclined surface 2282 on the oil-blocking sub-tube 214 is located within the air outlet 2142, that is, the partial projection of the blocking plate 222 on the oil-blocking sub-tube 214 is located within the air outlet 2142, so that when the atomization center air pipe 200 is inverted or lying flat, the blocking plate 222 can quickly rotate toward the oil-blocking sub-tube 214, thereby facilitating the blocking plate 222 to quickly close the air outlet 2142, thereby increasing the rate at which the blocking plate 222 blocks the air outlet 2142, and thus reducing the volume of smoke oil flowing into the air outlet 2142.

[0040] The present application also provides an atomization structure comprising the atomization central air pipe described in any of the above embodiments. The atomization structure further comprises an atomizer seat and an atomizer core. The atomizer seat is connected to the atomizer pipe and defines an air inlet. The air inlet communicates with the interior of the atomizer pipe. The atomizer core is housed within the atomizer pipe. In this embodiment, the atomization central air pipe comprises an atomizer pipe and a connecting pipe. The connecting pipe comprises a pipe body and an oil-blocking sub-tube. The pipe body is connected to the atomizer pipe and the oil-blocking sub-tube, respectively. The oil-blocking sub-tube is at least partially located within the atomizer pipe, the outer wall of the oil-blocking sub-tube being connected to the inner wall of the atomizer pipe, and the oil-blocking sub-tube has an air outlet. The air outlet communicates with the interior of the atomizer pipe and is positioned away from the inner wall of the atomizer pipe to form a barrier. The barrier is used to prevent condensate from being inhaled by the user during smoking or to prevent e-liquid from escaping from the central air pipe. By adding a fuel blocker and positioning the air outlet away from the inner wall of the atomizer tube, the sidewalls of the air outlet are offset from the inner wall of the atomizer tube, allowing the bottom of the fuel blocker to protrude from the inner wall of the atomizer tube. This prevents condensation and e-liquid from flowing from the inner wall of the atomizer tube toward the air outlet, reducing the chance of condensation and e-liquid escaping from the atomizer center's air pipe. Furthermore, the blocking portion serves two purposes: 1. It prevents condensation generated by smoke from flowing along the tube wall and into the user's mouth with the smoke flow; and 2. It prevents e-liquid from detaching from the oil guide cotton and flowing out along the inner tube wall during transportation.

[0041] The atomization center air pipe has its own blocking structure. When the atomization structure is inverted or lying flat, the blocking structure in the atomization center air pipe confines the smoke oil in the atomization pipe, thereby reducing the probability of the smoke oil overflowing through the inner wall of the atomization pipe. The atomization seat is connected to the atomization pipe, and the atomization battery core is arranged in the atomization pipe. Most of the smoke oil blocked by the atomization center air pipe returns to the atomization pipe and is reheated and atomized by the atomization battery core to form smoke.

[0042] In one embodiment, the atomizing tube is provided with a liquid guide hole, and the liquid guide hole is used to introduce the liquid to be atomized into the atomizing tube, and the atomizing core is used to atomize and heat the liquid to be atomized. In this embodiment, the atomizing core is provided in the atomizing tube, and the atomizing core is used to heat and atomize the liquid to be atomized so that the liquid to be atomized forms smoke. The liquid guide hole is provided in the atomizing tube, and the tobacco oil in the atomizing tube enters the atomizing tube through the liquid guide hole, providing the atomizing core with atomizable liquid to be atomized, so that the atomizing core can contact the liquid to be atomized, thereby facilitating the atomizing core to heat the liquid to be atomized into smoke and then directly output it through the air outlet and the air vent. Furthermore, the atomizer core is embedded in the atomizer tube and comprises a heating mechanism consisting of atomizer cotton and a heating wire. The atomizer core is disposed adjacent to the liquid guide hole, and the e-liquid flows through the liquid guide hole to infiltrate the atomizer cotton of the atomizer core, thereby achieving heating and atomization of the e-liquid. Furthermore, the liquid to be atomized comprises at least one of condensate and e-liquid.

[0043] The present application also provides an electronic atomizer, comprising the atomization structure described in any of the above embodiments, and further comprising an oil cup. The atomization structure is disposed within the oil cup, and a liquid storage tank is formed between the oil cup, the connecting tube, and the atomizer seat. The liquid storage tank is used to store liquid to be atomized. The oil cup has an air outlet channel, which is connected to the air outlet. In this embodiment, the atomization central air pipe comprises an atomization pipe and a connecting pipe. The connecting pipe comprises a tube body and an oil-blocking sub-tube. The tube body is connected to the atomization pipe and the oil-blocking sub-tube, respectively. The oil-blocking sub-tube is at least partially located within the atomization pipe, the outer wall of the oil-blocking sub-tube being connected to the inner wall of the atomization pipe, and the oil-blocking sub-tube has an air outlet. The air outlet is connected to the interior of the atomization pipe and is positioned away from the inner wall of the atomization pipe to form a barrier. The barrier is used to prevent condensate from being inhaled into the user's mouth during smoking or to prevent the e-liquid from flowing out of the central air pipe. By adding a fuel blocker tube and moving the air outlet away from the inner wall of the atomizer tube, the side wall of the air outlet is offset from the inner wall of the atomizer tube, so that the bottom of the fuel blocker tube protrudes from the inner wall of the atomizer tube, thereby preventing condensation on the inner wall of the atomizer tube and the flow of tobacco oil to the air outlet, thereby reducing the probability of condensation and tobacco oil flowing out of the atomization center air pipe, thereby reducing the probability of condensation and tobacco oil flowing out of the electronic atomizer. In addition, the blocking portion is used for two purposes: 1. It blocks the condensation generated by smoke during smoking from flowing along the tube wall with the smoke flow and being inhaled into the mouth of the user; 2. It is used to prevent tobacco oil from detaching from the oil guide cotton and flowing out along the inner tube wall during transportation.

[0044] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they 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 numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
