Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] After inhalation, aerosols from nebulizers can flow back into the atomizing section of the atomizing chamber, affecting the vaping experience. Therefore, a liquid suction section is placed between the mouthpiece and the atomizing chamber to condense and absorb the flowing aerosol. However, even after the liquid suction section has absorbed liquid, vibrations during use can still cause condensate to flow back into the atomizing section. Alternatively, the liquid suction section may become saturated after prolonged use, and the saturated condensate will also flow back into the atomizing section, still affecting the vaping experience.

[0039] In response to this problem, this utility model proposes a condensation reflux structure and atomization device, which can effectively improve the above-mentioned problems.

[0040] Reference Figures 1 to 4 According to the first aspect of the present invention, the condensation reflux structure includes: a nozzle 100, an atomizing chamber shell 200, an atomizing component 300, and a liquid suction part 400.

[0041] The nozzle 100 is provided with an air outlet channel 101.

[0042] The nozzle 100 is located at one end of the atomizing chamber shell 200. The atomizing chamber shell 200 is provided with a partition 201. The atomizing chamber shell 200 defines an atomizing chamber 202 on the side of the partition 201 away from the nozzle 100. A condensing chamber 203 is defined between the partition 201 and the nozzle 100. The condensing chamber 203 is connected to the air outlet channel 101. The atomizing chamber 202 and the condensing chamber 203 are separated by the partition 201. The partition 201 is provided with an air passage hole 204 and a return hole 205. Both the air passage hole 204 and the return hole 205 pass through the partition 201 along the direction of the suction airflow and connect the condensing chamber 203 and the atomizing chamber 202. The return hole 205 is located on the periphery of the air passage hole 204.

[0043] The atomizing component 300 is disposed within the atomizing chamber 202. The atomizing component 300 includes a liquid storage section 301 and an atomizing section 302. The liquid storage section 301 has an atomizing channel 303, and the atomizing section 302 is located at the end of the atomizing channel 303 away from the partition section 201. The liquid storage section 301 is used to store atomizing liquid, and the atomizing section 302 is used to heat the atomizing liquid stored in the liquid storage section 301 to atomize and generate an aerosol for the user to inhale. For example, the atomizing section 302 can be a heating wire or a heating mesh, and the liquid storage section 301 can be an empty liquid storage container, or it can be a liquid storage cotton or a porous liquid storage ceramic.

[0044] The liquid-absorbing part 400 is disposed within the condensation chamber 203. The liquid-absorbing part 400 is used to condense and absorb the aerosol returning from the exhaust channel 101. The liquid-absorbing part 400 has a through-hole 401 that extends through the liquid-absorbing part 400 along the direction of the suction airflow, allowing the aerosol to pass through. In this embodiment, the partition 201 is configured as a plate-like structure, and the liquid-absorbing part 400 is attached to the side of the partition 201 facing the suction nozzle 100. For example, the liquid-absorbing part 400 can be a liquid-absorbing element such as condensation cotton.

[0045] The atomizing channel 303, air passage 204, through hole 401 and air outlet channel 101 are connected by airflow in sequence. That is, the atomizing channel 303, air passage 204, through hole 401 and air outlet channel 101 are arranged in sequence along the direction of suction airflow. The return hole 205 is located on the periphery of the atomizing channel 303. That is, the return hole 205 and the atomizing channel 303 are offset radially from each other along the return hole 205.

[0046] When the user inhales, the nozzle 100 faces upwards. At this time, the airflow direction is deviated from the vertical direction by a certain angle. The atomizing section 302 heats the atomizing liquid in the liquid storage section 301, and the atomizing liquid atomizes to produce an aerosol. The aerosol passes through the atomizing channel 303, the air passage 204, the through hole 401, and the air outlet channel 101 in sequence and is inhaled by the user. During this process, some aerosol will flow back from the air outlet channel 101 to the condensing chamber 203. At this time, the liquid absorption section 400 in the condensing chamber 203 can condense and absorb the backflowing aerosol, forming condensate in the liquid absorption section 400. If used... During the process, if the equipment vibrates or the liquid suction section 400 becomes saturated with liquid after prolonged use, condensate will seep out from the liquid suction section 400. At least some of the condensate will flow into the atomizing chamber 202 through the return hole 205. Since the return hole 205 is located on the periphery of the atomizing channel 303, the condensate passing through the return hole 205 will not flow directly into the atomizing channel 303, but will flow to the liquid storage section 301 and be absorbed by the liquid storage section 301. That is, by setting the return hole 205, the amount of condensate flowing back to the atomizing section 302 can be reduced, ensuring the sucking experience. In addition, the condensate is recovered by the liquid storage section 301, which can also reduce waste.

[0047] Reference Figure 4 As shown, in some embodiments, multiple return holes 205 are provided, and the multiple return holes 205 are arranged at intervals on the same circumference. Specifically, the multiple return holes 205 are evenly spaced along the circumferential direction of the air passage hole 204. On the one hand, by arranging multiple return holes 205, more condensate can flow back into the atomizing chamber 202 through the return holes 205 and be absorbed by the liquid storage section 301, while less condensate flows from the air passage hole 204 into the atomizing chamber 202 and flows to the atomizing section 302 through the atomizing channel 303. On the other hand, by arranging multiple return holes 205 at intervals on the same circumference, condensate can flow out from the liquid suction section 400 evenly and flow back into the liquid storage section 301 evenly.

[0048] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the projection of the air passage 204 along the direction of the suction airflow is located within the projection range of the through hole 401 along the direction of the suction airflow. That is, the size of the air passage 204 is smaller than the size of the through hole 401. The advantage of this arrangement is that the liquid suction part 400 will not cover the air passage 204, which can reduce the probability of the condensate seeping out of the liquid suction part 400 flowing back into the atomization channel 303 through the air passage 204 to a greater extent. The condensate seeping out of the liquid suction part 400 will flow more from the return hole 205 into the atomization chamber 202 and be absorbed by the liquid storage part 301 in the atomization chamber 202.

[0049] In one embodiment, the separator 201 has an annular protrusion 206 at one end near the nozzle 100. The annular protrusion 206 is distributed along the circumferential direction of the airway hole 204, and at least partially inserted into the through hole 401. It is understood that when the user is suctioning, the nozzle 100 is usually facing upward and tilted. At this time, the suction airflow direction is deviated from the vertical direction by a certain angle. Even if the liquid suction part 400 does not cover the airway hole 204, due to the tilt of the device... The condensate from the liquid absorption section 400 may also seep out from the hole wall of the through hole 401 and fall into the air passage hole 204, and then enter the atomization channel 303. Therefore, in this embodiment, an annular protrusion 206 is provided on the partition section 201, so that the annular protrusion 206 is at least partially inserted into the through hole 401 to prevent the condensate on the liquid absorption section 400 from seeping out from the through hole 401 and entering the air passage hole 204, thereby further improving the effect of preventing the condensate from flowing back to the atomization section 302. Furthermore, along the direction of the suction airflow, the end of the annular protrusion 206 near the nozzle 100 is flush with the end of the liquid-absorbing part 400 near the nozzle 100, or the end of the annular protrusion 206 near the nozzle 100 protrudes beyond the end of the liquid-absorbing part 400 near the nozzle 100. This maximizes the prevention of condensate on the liquid-absorbing part 400 from seeping out through the through hole 401 and entering the air passage 204. It should be noted that an inner extension tube 103 is provided inside the nozzle 100, and the air outlet channel 101 is formed within the inner extension tube 103. A gap needs to be maintained between the end of the annular protrusion 206 near the nozzle 100 and the inner extension tube 103 of the nozzle 100 to allow the returning aerosol to pass through and be condensed and absorbed by the liquid-absorbing part 400.

[0050] Reference Figure 1 As shown, in some embodiments, a first gap (not shown) is provided between the liquid storage section 301 and the partition section 201 along the direction of the suction airflow. On the one hand, if the liquid storage section 301 is directly attached to the partition section 201, the atomized liquid stored in the liquid storage section 301 can easily enter the suction section 400 through the return hole 205 on the partition section 201 and be absorbed by the suction section 400, resulting in waste of the atomized liquid. Therefore, in this embodiment, by providing a first gap between the liquid storage section 301 and the partition section 201, the liquid storage section 301 and the return hole 205 on the partition section 201 are separated, preventing the atomized liquid stored in the liquid storage section 301 from entering the suction section 400 through the return hole 205 and avoiding waste of the atomized liquid. On the other hand, while the atomized liquid is being consumed, external gas is also needed to replenish the liquid storage section 301 to maintain air pressure balance. The first gap connects to the atomization channel 303, thus making it easier for the condensation return structure of this embodiment to maintain air pressure balance.

[0051] In one embodiment, reference is made to Figure 1 and Figure 4Along the direction of the suction airflow, a limiting part 207 is provided at one end of the separator 201 near the liquid storage part 301. The limiting part 207 is located within the first gap and is used to abut against the end of the liquid storage part 301 near the separator 201 along the direction of the suction airflow. This prevents the liquid storage part 301 from moving towards the separator 201 even if the equipment shakes, thus maintaining a first gap between the separator 201 and the liquid storage part 301. It is understood that to ensure the limiting effect, multiple limiting parts 207 can be provided and arranged in a block structure, with the multiple limiting parts 207 evenly distributed along the circumference of the air passage 204.

[0052] Reference Figure 1 and Figure 2 As shown, in some embodiments, a sealing element 500 is provided between the nozzle 100 and the atomizing chamber shell 200. The sealing element 500 is located on the side of the liquid suction section 400 near the nozzle 100 along the direction of the suction airflow. By providing the sealing element 500, the installation gap between the nozzle 100 and the atomizing chamber shell 200 is sealed, preventing aerosol leakage and reducing waste. For example, the sealing element 500 may be made of silicone or rubber. In some specific embodiments, the sealing element 500 is sleeved on the inner extension tube 103 of the nozzle 100, and the outer peripheral wall of the sealing element 500 abuts against the inner peripheral wall of the atomizing chamber shell 200.

[0053] Reference Figure 1 As shown, in some embodiments, a second gap is provided between the seal 500 and the liquid absorption part 400 along the direction of the suction airflow. By providing the second gap, a certain space can be provided for the flow of the backflowing aerosol, which helps the liquid absorption part 400 to absorb the backflowing aerosol.

[0054] Reference Figure 1 and Figure 2 Figure 1 According to the second aspect of the present invention, the atomizing device includes the condensation reflux structure of the first aspect embodiment described above. The atomizing device further includes a housing 102, which is sleeved on the outside of the atomizing chamber shell 200. One end of the housing 102 along the direction of the suction airflow is connected to the nozzle 100.

[0055] In the atomizing device with the above-described structure, when the user inhales, the atomizing unit 302 heats the atomizing liquid in the storage unit 301, atomizing the liquid to generate aerosol. The aerosol passes sequentially through the atomizing channel 303, the air passage 204, the through hole 401, and the air outlet channel 101 and is inhaled by the user. During this process, some aerosol flows back from the air outlet channel 101 to the condensing chamber 203. At this time, the liquid absorption unit 400 in the condensing chamber 203 can condense and absorb the backflowing aerosol, forming condensate in the liquid absorption unit 400. If the device vibrates during use... Alternatively, after the liquid absorption section 400 becomes saturated with liquid for a long time, condensate seeps out from the liquid absorption section 400. At least some of the condensate will flow into the atomizing chamber 202 through the return hole 205. Since the return hole 205 is located on the periphery of the atomizing channel 303, the condensate passing through the return hole 205 will not flow directly into the atomizing channel 303, but will flow to the liquid storage section 301 and be absorbed by the liquid storage section 301. That is, by setting the return hole 205, the amount of condensate flowing back to the atomizing section 302 can be reduced, ensuring the sucking experience. In addition, the condensate is recovered by the liquid storage section 301, which can also reduce waste.

[0056] It should be noted that other aspects of the atomizing device disclosed in this utility model can be found in the prior art, and will not be repeated here.
