[0002] In existing low-capacity refillable aerosol generators, the atomizer structure size is often compressed to the extreme in order to achieve a compact design and easy portability.

[0003] However, within a limited space, traditional atomizer coils and air inlets typically use a straight-through connection structure, resulting in a short airflow path and a lack of effective liquid barrier mechanisms. When e-liquid leaks from the atomizer coil, it can easily leak directly to the outside through the air inlet, affecting user experience and product reliability.

[0004] Therefore, it is necessary to provide a new atomizer and aerosol generating device. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the purpose of this utility model embodiment is to provide an atomizer and aerosol generating device. By setting an air-circulating circuit and a flow guide rib on the air guide bracket, leakage of atomizing liquid can be prevented, improving product reliability and user experience, while maintaining smooth airflow.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an atomizer, comprising a shell, an atomizing component disposed inside the shell, and an air guide support disposed at the bottom of the shell. The air guide support includes an air passage, which includes an air circulation loop and multiple sets of rib units disposed within the air circulation loop. Outside air flows to the atomizing component through the air circulation loop. The rib units are spaced apart along the centerline of the air circulation loop. Each rib unit includes an upper rib and a lower rib fixed to opposite side walls of the air circulation loop. The upper and lower ribs of adjacent rib units are staggered along the centerline of the air circulation loop. They are located between adjacent upper ribs or adjacent lower ribs on the same side wall of the air circulation loop, forming independent segmented liquid storage chambers together with the inner wall of the air circulation loop. When a small amount of atomized liquid seeps out from the atomizing component, the atomized liquid remains in the segmented liquid storage chambers.

[0007] Furthermore, the air guide bracket also includes a central mounting groove, a top fastening part, and a bottom end. The bottom part of the atomizing component is fixedly installed in the mounting groove, and an air inlet groove is provided at the bottom of the mounting groove.

[0008] Furthermore, the atomizer also includes a seal and a bottom cover. The seal is located on the upper part of the air guide bracket, and a sealing rib is provided on the outer side of the seal.

[0009] Furthermore, the bottom of the sealing element is provided with a groove portion, and the fastening portion cooperates with the groove portion to fasten and fix the sealing portion.

[0010] Furthermore, one end of the air intake channel is located on the bottom surface of the bottom end, the other end of the air intake channel is connected to the air circulation loop, the air inlet is located on the side surface away from the air intake channel, and the air inlet is connected to the other end of the air intake groove and the air circulation loop respectively.

[0011] Furthermore, the projected portions of the upper and lower stiffeners of the adjacent stiffener units overlap.

[0012] Furthermore, an electrode mounting hole is provided at the bottom end of the air guide bracket. The electrode mounting hole is located below the mounting groove.

Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0025] like Figure 1-3 As shown, an embodiment of this utility model provides an atomizer 100, including a housing 1, an atomizing component 2 disposed inside the housing 1, and a sealing member 3 and an air guide bracket 4 disposed at the bottom of the housing. The atomizing component 2 is used to heat and atomize the atomizing liquid to generate an aerosol. The air guide bracket 4 is used to guide the airflow input and store the atomizing liquid seeping from the atomizing component 2. The housing 1, the atomizing component 2, and the sealing member 3 together form a liquid storage chamber 11 for storing the atomizing liquid. Additionally, the housing 1 is also used to output the generated aerosol.

[0026] In some of these embodiments, such as Figure 2As shown, the outer casing 1 includes a mouthpiece 12, a mounting port located at the end away from the mouthpiece 12, and an output tube 13 located inside the outer casing 1. The mouthpiece 12 is located at the top of the outer casing 1 and serves as the aerosol output port, allowing the user to inhale the aerosol generated by the atomizing assembly 2. The mounting port is the open end at the bottom of the outer casing 1, suitable for installing the sealing element 3 and the air guide bracket 4. The top end of the output tube 13 communicates with the mouthpiece 12, and the bottom end of the output tube 13 is fixedly connected to the atomizing assembly 2. The aerosol formed by the atomized liquid stored in the liquid storage chamber 11 after being heated and atomized by the atomizing assembly 2 is output to the mouthpiece 12 through the output tube 13 for the user to inhale.

[0027] In some of these embodiments, such as Figure 4 As shown, the seal 3 and the air guide bracket 4 are located at the mounting port at the bottom of the housing 1. The seal 3 is located on the upper part of the air guide bracket 4, and the outer surface of the seal 3 is shaped to fit the inner wall of the housing 1, for mounting the seal 3 on the inner wall at the bottom of the housing 1. The upper end face of the seal 3, the inner wall of the housing 1, and the outer surface of the atomizing component 2 enclose a liquid storage cavity 11, that is, the upper end face of the seal 3 is the bottom inner wall of the liquid storage cavity 11.

[0028] In some of these embodiments, such as Figure 5 As shown, a sealing rib 31 is provided on the outer surface of the seal 3. The sealing rib 31 surrounds the outer surface of the seal 3 to form an annular protrusion, and at least one sealing rib 31 is provided. As an example, two sealing ribs 31 are provided. The sealing rib 31 makes the seal 3 and the inner wall of the outer shell 1 form an interference fit, thereby enhancing the sealing effect between the seal 3 and the inner wall of the outer shell 1.

[0029] In some embodiments, a mounting hole 32 is provided in the center of the seal 3, extending through both ends of the seal 3. The diameter of the mounting hole 32 matches the outer diameter of the atomizing component 2, and the mounting hole 32 is suitable for fixing the lower part of the atomizing component 2. A limiting protrusion 321 is provided on the inner wall of the mounting hole 32, and at least one limiting protrusion 321 is provided. As an example, two limiting protrusions 321 are provided. The limiting protrusions 321 ensure an interference fit between the mounting hole 32 of the seal 3 and the atomizing component 2, thereby preventing the bottom of the atomizing component 2 from moving within the first mounting hole 32.

[0030] In some embodiments, the bottom of the seal 3 is provided with a groove 33, the shape of which matches the top of the air guide bracket 4. The groove 33 is used to fix the seal 3 and the air guide bracket 4, preventing the seal 3 and the air guide bracket 4 from separating during assembly or use. A limiting groove 34 is also provided on the groove 33, with two symmetrically provided grooves, to limit the air guide bracket 4 and prevent misalignment between the seal 3 and the air guide bracket 4 during assembly or use.

[0031] In some embodiments, the seal 3 is also provided with a through injection hole 35, which is located on one side of the first mounting hole 32 and is connected to the liquid storage chamber 11 for injecting atomizing liquid into the liquid storage chamber 11 through the injection hole 35.

[0032] In some of these embodiments, such as Figure 6-8 As shown, the air guide bracket 4 includes a centrally located mounting groove 41, a top-mounted fastening portion 42, an air passage portion 43, and a bottom end portion 44. The mounting groove 41 is located at the top center of the air guide bracket 4, and its position corresponds to the mounting hole 32 of the sealing member 3. The diameter of the mounting groove 41 matches the bottom outer diameter of the atomizing assembly 2, and the mounting groove 41 is suitable for fixing the bottom portion of the atomizing assembly 2. An air inlet groove 45 is provided at the bottom of the mounting groove 41. The air inlet groove 45 is located at the bottom of the mounting groove 41, and its diameter is smaller than that of the mounting groove 41 to prevent the atomizing assembly 2 from shifting into the air inlet groove 45. The internal passage of the atomizing assembly 2 communicates with the air inlet groove 45, which is used to collect externally input gas and input it into the internal passage of the atomizing assembly 2.

[0033] In some embodiments, the shape of the fastening part 42 matches the groove part 33 of the seal 3, and the fastening part 42 and the groove part 33 are fastened and fixed to achieve a fixed connection between the seal 3 and the air guide bracket 4, preventing the seal 3 and the air guide bracket 4 from separating during assembly or use. The fastening part 42 is also provided with limiting protrusions 46, two of which are symmetrically provided. The shape and position of the limiting protrusions 46 match the limiting groove 34 to prevent misalignment between the seal 3 and the air guide bracket 4 during assembly or use.

[0034] In some embodiments, the air passage 43 includes an air intake passage 431, an air circulation loop 432, an air inlet 433, and multiple sets of stiffening plate units 434 disposed within the air circulation loop 432. One end of the air intake passage 431 is disposed on the bottom surface of the bottom end 44, and the other end of the air intake passage 431 is connected to the air circulation loop 432. The air inlet 433 is located on a side surface away from the air intake passage 431, and the air inlet 433 is connected to the air intake groove 45 and the other end of the air circulation loop 432, respectively. Outside air flows to the atomizing component 2 through the air circulation loop 432. Rib units 434 are distributed at intervals along the center line of the air circulation loop. Each rib unit 434 includes an upper rib and a lower rib fixed to opposite side walls of the air circulation loop. The projected portions of the upper and lower ribs of adjacent rib units 434 overlap, and the upper and lower ribs of adjacent rib units 434 are staggered along the center line of the air circulation loop 432. They are located between adjacent upper ribs or adjacent lower ribs on the same side wall of the air circulation loop 432, and together with the inner wall of the air circulation loop 432, they enclose independent segmented liquid storage chambers. When a small amount of atomized liquid seeps out from the atomizing component, the atomized liquid remains in the segmented liquid storage chambers, preventing the atomized liquid from seeping out to the outside through the air intake channel 431 and reducing the user experience. When a user inhales the atomizer 100 through the mouthpiece 12, the external airflow enters through the air intake channel 431 under negative pressure, then passes through the air circulation loops 432 located on both sides, converges at the air intake port 433, and then enters the air intake slot 45. From the air intake slot 45, it enters the interior of the atomizing component 2. The external airflow mixes with the aerosol generated by heating the mist through the atomizing component 2 and is then output to the mouthpiece 12 through the output pipe 13 for the user to inhale.

[0035] In some embodiments, the bottom end portion 44 is located below the air passage portion 43, and an annular sealing groove 442 is provided on the side of the bottom end portion 44. A sealing ring 441 is provided in the annular sealing groove 442. The sealing ring 441 is interference-fitted with the inner side wall of the outer shell 1 to achieve a sealed and fixed connection between the air guide bracket 4 and the outer shell 1.

[0036] In some embodiments, an electrode mounting hole 47 is provided on the bottom end 44 of the air guide bracket 4. The electrode mounting hole 47 is located on the bottom end face of the bottom end 44 and below the mounting groove 41. There are two electrode mounting holes 47, and positive and negative electrodes are respectively installed in the electrode mounting holes 47. The positive and negative electrodes are electrically connected to the atomizing component 2.

[0037] In some embodiments, the air guide bracket 4 is also provided with a placement hole 48, the position of which matches the liquid injection hole 35 on the seal 3.

[0038] In some embodiments, the atomizer 100 also includes a bottom cover 5 and a liquid injection plug 6, which is installed through a placement hole 48 and seals the liquid injection hole 35.

[0039] In some of these embodiments, such as Figure 9 As shown, the bottom cover 5 mates with the outer side of the mounting port of the outer shell 1. The bottom cover 5 has a connection port 51, which is connected to the inlet end of the air intake channel 431 on the air guide bracket 4, ensuring that external air can enter the air guide bracket 4 through the connection port 51. The connection port 51 is also connected to the electrode mounting hole 47 on the air guide bracket 4.

[0040] The atomizer 100 provided by this utility model sets an airflow circuit 432 on the air guide bracket 4 and uses guide ribs 434 to divide the air passage into segments, forming multiple segmented liquid storage chambers. When e-liquid seeps out from the atomizing component 2, the e-liquid can be stored in the segmented air passage chambers to prevent e-liquid leakage. This effectively prevents atomizing liquid leakage, improves product reliability and user experience, and maintains smooth airflow.

[0041] An embodiment of this utility model also provides an aerosol generating device, which includes the atomizer 100 provided in any of the above embodiments and a power supply device (not shown) for supplying power to the atomizer 100. Since the aerosol generating device possesses all the technical features of the atomizer 100 provided in any of the above embodiments, it has the same technical effects as the atomizer 100 described above.
