[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Example:

[0031] like Figures 1-5 As shown, in this embodiment, the atomizer includes: a housing 1, an air duct 2, and an atomizing assembly; the air duct 2 is fixed inside the housing 1 and defines an open liquid storage chamber 11; the atomizing assembly includes a support 3 fixed inside the housing 1, a liquid guide 4, a heating element 5, and an air passage 6 fixed inside the support 3, the liquid guide 4 is sandwiched between the heating element 5 and the support 3 and is in liquid communication with the liquid storage chamber 11, the side of the heating element 5 away from the liquid guide 4 and the support 3 enclose an atomizing channel communicating with the air duct 2; the support 3 includes a frame and a base 33 fixed to the bottom side of the frame, the top of the frame is sealed to the air duct 2 and the housing 1 through a first sealing element 7, the outer side of the base 33 is sealed to the inner wall of the housing 1 through a second sealing element 8, a buffer channel is formed between the outer side of the frame and the inner wall of the housing 1, and a return air channel communicating with the buffer channel and the liquid storage chamber 11 is provided between the outer side of the frame and the first sealing element 7, the buffer channel is at least partially connected to the outside atmosphere through the liquid guide 4.

[0032] Specifically, the frame also includes an air duct component 6. The side of the heating element 5 facing away from the liquid guide component 4 is enclosed by the air duct component 6 to form an atomization channel that connects to the air pipe 2. The frame and base 33 can be integrally connected or detachably assembled. The first sealing component 7 ensures a stable seal between the air pipe 2, the support 3, and the shell 1, reducing the probability of leakage. The return air channel connects the buffer channel and the liquid storage chamber 11. That is, the return air structure is not directly connected to the outside atmosphere, but is connected to the outside atmosphere through the buffer channel and the liquid guide component 4. Even if leakage occurs, it can be absorbed by the liquid guide component 4 and reheated for atomization. Alternatively, during return air, leakage in the buffer channel can flow back to the liquid storage chamber 11 through the return air channel under the action of the internal and external pressure difference, thereby further improving the leak-proof effect of the atomizer.

[0033] Furthermore, in this embodiment, the frame of the support 3 includes a first frame 31 and a second frame 32 that are fastened together. An insertion interface 3124 is formed at the bottom end of the first frame 31, and a liquid guide 4 is sandwiched between the first frame 31 and the heating element 5. The side of the air passage 6 away from the heating element 5 abuts against the second frame 32. The second frame 32 is also connected to a base 33, which abuts against the bottom end of the first frame 31. The base 33 has an electrode hole directly opposite the insertion interface 3124, and the electrode 53 passes through the electrode hole. That is, the base 33 is located below the first frame 31 and the second frame 32. The base 33 is integrally connected to or detachably connected to the second frame 32. The bottom end of the first frame 31 abuts against the top end of the base 33, so that the electrode 53 can pass through the electrode hole of the base 33 and be inserted into the insertion hole of the second frame 32 to achieve circuit connection with the heating element 5. The electrode 53 has good assembly stability and connection stability, and the assembly operation is simple. The first frame 31 and the second frame 32 are adapted to each other. One of the first frame 31 and the second frame 32 is provided with a limit buckle, and the other is provided with a limit hole corresponding to the limit buckle. When the two are assembled in place, the limit buckle is limited in the limit hole, thereby ensuring the stable connection between the first frame 31 and the second frame 32.

[0034] In this embodiment, the outer side of the base 33 is sealed to the inner wall of the housing 1 by the second sealing element 8. The design of the second sealing element 8 not only ensures a stable seal between the base 33 and the bottom shell, but also further improves the leak-proof performance of the atomizer; more specifically, the return air channel and the buffer channel are arranged between the first sealing element 7 and the second sealing element 8, sealing the upper and lower ends respectively, which can effectively improve the leak-proof performance of the atomizer.

[0035] In this embodiment, the first frame 31 includes an end wall portion 311 and a side enclosure portion 312 connected to the end of the end wall portion 311 away from the liquid storage chamber 11. The outer side wall of the end wall portion 311 is provided with a return air groove 3112. The side enclosure portion 312 has a limiting step 3113 protruding from the outer side of the end wall portion 311. The first sealing member 7 is sleeved on the end wall portion 311, and the first sealing member 7 is provided with a return air port 711 communicating with the return air groove 3112 and the liquid storage chamber 11. The first sealing member 7 and the limiting step 3113 are arranged at intervals to form a return air gap communicating with the return air groove 3112. The return air channel includes the return air gap, the return air groove 3112 and the return air port 711. Through the ingenious design between the end wall portion 311 and the side enclosure portion 312, a return air channel is formed that communicates with the buffer channel. The buffer channel can guide any atomized liquid that leaks out of the return air channel to the liquid guide component 4, thereby preventing leakage. In addition, the design of the first sealing component 7 and the second sealing component 8 forms a multi-layer sealing and leak-proof barrier, effectively preventing e-liquid leakage and efficiently solving the leakage problem of traditional electronic atomizers.

[0036] In this embodiment, a buffer groove 3121 extending circumferentially is provided on the outer periphery of the side enclosure 312. At least one end of the buffer groove 3121 is connected to the liquid guide 4, and the buffer groove 3121 is also connected to the return gas gap. The buffer groove 3121 and the inner wall of the shell 1 enclose each other to form a buffer channel. This design of the buffer channel forms a transition oil tank, and the oil is locked by the siphon effect of the transition oil tank, resulting in excellent leak-proof performance.

[0037] Furthermore, such as Figures 2-4 As shown, in this embodiment, the outer side of the side enclosure 312 is provided with a plurality of buffer slots 3121 spaced apart in the longitudinal direction, and the outer side of the side enclosure 312 is provided with a connecting port 3122 connecting two adjacent buffer slots 3121. The design of multiple buffer slots 3121 can form a multiple sealing mechanism for leakage, effectively preventing the atomizing liquid from overflowing and improving product reliability. Preferably, in this embodiment, both ends of the buffer slots 3121 are respectively connected to the liquid guiding member 4, so that the leakage in the buffer slots 3121 can be efficiently guided to the liquid guiding member 4. In some specific embodiments, the inner side of the side enclosure 312 is provided with a mounting slot 3125, and the side enclosure 312 has a notch 3123 connecting the mounting slot 3125 and the buffer slots 3121. The liquid guiding member 4 is fixed on the mounting slot 3125, so that the leakage in the buffer slots 3121 can smoothly reach the liquid guiding member 4 along the notch 3123.

[0038] In some specific embodiments, two adjacent connecting ports 3122 along the longitudinal direction of the side circumference 312 are staggered in the circumferential direction to extend the flow path within the high leakage buffer channel.

[0039] In this embodiment, the first sealing member 7 includes a top 71 with a return air port 711 and a first sealing portion 72 and a second sealing portion 73 bent and connected to both sides of the top 71. The first sealing portion 72 abuts between the end wall portion 311 and the vent pipe 2, and the second sealing portion 73 abuts between the end wall portion 311 and the housing 1. Specifically, the first sealing portion 72, the top 71, and the second sealing portion 73 form a limiting groove that matches the shape of the end wall portion 311, so that the first sealing member 7 can be sleeved on the first end arm, and the second sealing portion 73 abuts against the housing 1, and the first sealing portion 72 abuts against the outside of the vent pipe 2, ensuring the assembly stability and sealing stability between the housing 1, the frame, and the vent pipe 2.

[0040] In this embodiment, as Figures 1-5 As shown, a liquid guiding groove 3126 is also provided in the mounting groove 3125, and a liquid outlet 3111 is provided at one end of the side part 312 near the liquid storage cavity 11; a clearance opening 731 is provided on the first sealing member 7 to connect the liquid storage cavity 11 to the liquid outlet 3111, and the liquid guiding groove 3126 connects the liquid outlet 3111 to the liquid guiding member 4. Specifically, the liquid outlet 3111 can be located at the connection between the end wall portion 311 and the side portion 312. The end wall portion 311 has a liquid outlet 3111 that connects to the liquid storage cavity 11 and a liquid guide groove 3126 that connects the liquid outlet 3111 to the liquid guide member 4. The liquid guide groove 3126 is located inside the mounting groove 3125 and extends longitudinally. The liquid guide member 4 is embedded in the mounting groove 3125 and covers the liquid guide groove 3126 and the liquid outlet 3111. That is, the end of the liquid guide member 4 near the liquid storage cavity 11 can cover the liquid outlet 3111. The first sealing member 7 also has a relief opening 731 that connects the liquid storage cavity 11 to the liquid outlet 3111, so that the atomized liquid in the liquid storage cavity 11 can reach the liquid guide member 4 along the relief opening 731, the liquid outlet 3111 and the liquid guide groove 3126, and then be heated and atomized by the heating element 5 to form an aerosol. A longitudinally extending liquid guide groove 3126 is provided, which connects the lower liquid port 3111 to the liquid guide component 4. This design can reduce the lateral dimension of the support 3 and realize the miniaturization of the atomizer. During use, the liquid in the storage chamber 11 can enter the liquid guide component 4 through the lower liquid port 3111 and the liquid guide groove 3126 with the help of gravity, and then be heated and atomized by the heating element 5. The atomization effect is good, which improves the utilization rate of the atomized liquid and helps to reduce the residue of the atomized liquid.

[0041] In this embodiment, the housing 1 and / or the vent pipe 2 are made of metal, that is, the housing 1 and / or the vent pipe 2 can be made of hard metal. Preferably, the housing 1 and / or the vent pipe 2 are hardware components.

[0042] In some embodiments, the housing 1 is made of a metal tube, which can be designed as a straight tube structure, eliminating the need for mold making and reducing component costs; it allows for thinner wall thickness designs, helping to reduce the overall size of the atomizer, making it lighter and easier to carry; the metal surface of the metal tube has lower roughness and surface tension, which can reduce the residue of atomized liquid on the inner wall, avoiding waste and reducing clogging problems caused by residue accumulation; it has better chemical corrosion resistance, does not react chemically with the atomized liquid, can better reduce the precipitation of harmful substances, and improve food safety; the metal tube also has better structural strength and drop resistance, which can extend the service life of the atomizer. In some embodiments, the vent pipe 2 can also be designed as a thin-walled metal pipe with good surface tension on its inner surface, which can effectively prevent condensate residue on the inner wall. This reduces the amount of atomizing liquid remaining in the pipe, avoiding waste and increasing heat absorption efficiency. Compared to traditional plastic materials, the metal pipe with good thermal conductivity can effectively reduce the flue gas temperature. The vent pipe 2 can also be precision-machined to ensure consistent inner diameter at all height positions, ensuring stable airflow and improving atomization effect and user experience. The metal pipe also has excellent heat resistance, is not easily deformed or aged at high temperatures, and can maintain a stable airflow channel, ensuring the continuity and consistency of the atomization process. It is recyclable and environmentally friendly. In this embodiment, the metal pipe can be a stainless steel pipe.

[0043] In this embodiment, the wall thickness of the housing 1 and / or the vent pipe 2 is 0.15mm to 0.2mm. For example, the wall thickness of the housing 1 can be set to 0.15mm, 0.16mm, 0.17mm, 0.18mm, 0.19mm, 0.20mm, etc., and is not limited herein. Similarly, the wall thickness of the vent pipe 2 can be set to 0.15mm, 0.16mm, 0.17mm, 0.18mm, 0.19mm, 0.20mm, etc., and is not limited herein.

[0044] In this embodiment, the liquid guiding component 4 is oil-guiding cotton, and the fiber direction of the oil-guiding cotton extends longitudinally; that is, the fiber direction of the oil-guiding cotton is consistent with the gravity direction of the atomizing liquid, making the delivery of the atomizing liquid smoother and more stable. For example, the oil-guiding cotton can be longitudinally shaped flax cotton, and the fiber direction of the cotton is consistent with the gravity direction of the atomizing liquid, resulting in smooth liquid guiding and stable liquid guiding effect.

[0045] like Figure 4 and 5As shown, in this embodiment, the heating element 5 includes a heating section 51 and electrode sections 52 connected to both ends of the heating section 51. The liquid inlet 3111 is staggered from the heating section 51 in the longitudinal direction. The heating section 51 is the core heating area; staggering the liquid inlet 3111 from the core heating area effectively reduces leakage due to rapid liquid dispensing and avoids the problem of sucking or gurgling sounds caused by rapid dispensing in the core heating area. In this embodiment, at least one of the two electrode sections 52 is sheet-shaped, and the sheet-shaped electrode section 52 is correspondingly arranged on both sides of the liquid guide 4 with the liquid inlet 3111. That is, the electrode section 52 presses the liquid guide 4 tightly against the liquid inlet 3111, which helps reduce the risk of leakage. In this embodiment, in the longitudinal direction, the height of the end of the liquid guide groove 3126 away from the liquid inlet 3111 is higher than or equal to the height of the heating section 51; this allows the atomized liquid to smoothly reach the core heating area and be fully heated and atomized by the heating element 5.

[0046] In this embodiment, as Figure 5 As shown, the atomizing assembly also includes electrodes 53 respectively disposed corresponding to the two electrode sections 52; the end of the support 3 away from the liquid storage chamber 11 is also provided with a connector 3124 corresponding to each electrode 53; the end of the electrode section 52 away from the heating section 51 has a bent portion 521, which extends into the connector 3124, and the electrode 53 can be press-fitted into the corresponding connector 3124 and electrically connected to the bent portion 521. In this embodiment, the design of the bent portion 521 eliminates the need for a welded shaft hole structure, and allows the structure of the electrode section 52 to be more flexible in adapting to atomizer structures of different sizes or shapes, simplifying the installation process.

[0047] In this embodiment, an end assembly 9 is also included. The end assembly 9 includes a third seal 92 and a mouthpiece cap 91 with an air outlet 911. The air outlet 911 is connected to the air duct 2. The third seal 92 is sealed and abuts against the air duct 2, the housing 1, and the mouthpiece cap 91. The aerosol generated in the atomization channel mixes with air and can be output to the outside of the atomizer along the air duct 2 and the air outlet 911 for the user to inhale. The third seal 92 seals against the air duct 2, the housing 1, and the mouthpiece cap 91, ensuring both the assembly stability of the mouthpiece cap 91 and the sealing stability between the air duct 2, the mouthpiece cap 91, and the housing 1, preventing leakage of the atomized liquid along the end.

[0048] In this embodiment, an extension 912 is connected to the end of the nozzle cap 91 near the atomizing component. A third sealing member 92 is fitted onto the outside of the extension 912, and the third sealing member 92 abuts against the inner wall of the housing 1 and the outside of the vent tube 2. That is, a groove adapted to the shape of the extension 912 is formed in the third sealing member 92, so that the third sealing member 92 can be fitted onto the outside of the extension 912. After the nozzle cap 91 with the third sealing member 92 fitted is inserted into the housing 1 from the top, the third sealing member 92 can abut against the inner wall of the housing 1 and the outside of the vent tube 2, respectively, to achieve a stable installation between the vent tube 2, the nozzle cap 91, and the housing 1. In this embodiment, the first sealing member 7, the second sealing member 8, and the third sealing member 92 can all be silicone parts.

[0049] In this embodiment, the atomizer assembly operation is simple and convenient. The assembly process can be carried out as follows: First, put the third sealing element 92 on the mouthpiece cover 91, and then press the mouthpiece cover 91 with the third sealing element 92 on it into the housing 1 from the top; assemble the first bracket 3, the liquid guide 4, the heating element 5, the air passage 6 and the second bracket 3 into one piece, and put the first sealing element 7 and the second sealing element 8 on both ends respectively to form a heating core semi-finished product; then put the heating core semi-finished product into the housing 1 from the bottom.
