In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0044] Reference Figures 1 to 3 The utility model provides an atomizing device, which includes a liquid storage tank 100, a base 200 and a base 300. A liquid storage cavity 110 is provided inside the liquid storage tank 100. The liquid storage cavity 110 is used to store atomized liquid. The atomized liquid can be set to oil, liquid medicine, nutrient solution, etc. The atomized liquid can be atomized to form an aerosol.

[0045] The base 200 is located in the liquid storage tank 100. The base 200 has a lower liquid hole 210, which is connected to the liquid storage chamber 110. The base 300 is connected to the liquid storage tank 100 and cooperates with the base 200 to define an atomization chamber 220. An atomization core 101 is provided in the atomization chamber 220. The atomization core 101 is installed on the base 200 and is located on the side of the base 200 facing away from the liquid storage chamber 110. The atomized liquid in the liquid storage chamber 110 seeps to the atomization core 101 through the lower liquid hole 210. When the atomization core 101 is energized, the atomized liquid is atomized and an aerosol is generated. The aerosol is diffused in the atomization chamber 220 for the user to inhale.

[0046] The atomizing device of the present invention further includes a ventilation tube 400. The base 200 is further provided with a mounting hole 230. The ventilation tube 400 is installed in the mounting hole 230. The liquid storage chamber 110 and the atomizing chamber 220 are connected via the ventilation tube 400. The base 300 has an air inlet 310. The air inlet 310 connects the atomizing chamber 220 with the outside atmosphere. In this way, the liquid storage chamber 110 is connected to the outside atmosphere via the ventilation tube 400, the atomizing chamber 220, and the air inlet 310. External air can enter the liquid storage chamber 110 through the ventilation tube 400 to adjust the air pressure in the liquid storage chamber 110 so that the air pressure in the liquid storage chamber 110 is balanced with the outside atmosphere.

[0047] Specifically, when the atomizer core 101 is working, the atomized liquid in the liquid storage chamber 110 flows toward the atomizer core 101 through the lower liquid hole 210. The atomizer core 101 continuously consumes the atomized liquid in the liquid storage chamber 110 and generates aerosol. The atomized liquid in the liquid storage chamber 110 decreases, causing the air pressure in the liquid storage chamber 110 to decrease. When the air pressure in the liquid storage chamber 110 is lower than the threshold, external air enters the liquid storage chamber 110 through the air inlet 310, the atomizing chamber 220 and the ventilation tube 400, causing the air pressure in the liquid storage chamber 110 to rise again, thereby realizing adaptive regulation of the air pressure in the liquid storage chamber 110 and keeping the air pressure in the liquid storage chamber 110 balanced with the external atmosphere.

[0048] It should be noted that in the related art, the ventilation hole connecting the liquid storage chamber 110 and the atomization chamber 220 is directly formed using the base 200. Based on usage requirements, the base 200 is usually made of materials such as silicone with high flexibility, and the specifications of the ventilation hole are relatively small. The aperture accuracy is greatly affected by the processing accuracy of the base 200. When the aperture is too small, it is difficult for the external atmosphere to enter the liquid storage chamber 110 through the ventilation hole, resulting in the atomized liquid being unable to seep normally. When the aperture is too large, the atomized liquid in the liquid storage chamber 110 is easy to leak downward from the ventilation hole, resulting in leakage. The present invention utilizes the ventilation tube 400 to connect the liquid storage chamber 110 and the atomization chamber 220. After the ventilation tube 400 is processed as a separate component, it is installed in the mounting hole 230 of the base 200. Since the ventilation tube 400 does not need to be formed at the same time as the base 200, the processing accuracy of the ventilation tube 400 is not affected by the processing accuracy of the base 200. The ventilation tube 400 can be processed and formed using a material with suitable hardness, strength and plasticity. The aperture accuracy of the ventilation tube 400 is high, which can maintain the balance of internal and external air pressure, reduce the probability of poor liquid flow or leakage of the atomized liquid, and enhance the user experience of the atomization device.

[0049] In addition, when ventilation is performed through the ventilation tube 400, the external air enters the atomizing chamber 220 through the air inlet 310 and then directly enters the liquid storage chamber 110 through the ventilation tube 400. The air path during the ventilation process is short and simple, and ventilation can be performed quickly.

[0050] For example, ventilation tube 400 can be made of a metal material with high hardness, high strength, and high plasticity, such as alloy or stainless steel, and the processing methods are not limited to machining and casting. Ventilation tube 400 can also be made of non-metallic materials such as POM (polyoxymethylene), PVC (polyethylene), and nylon, and the processing methods are not limited to machining and injection molding.

[0051] It is understandable that by separately processing the ventilation tube 400 and then installing the ventilation tube 400 on the base 200, the aperture accuracy of the ventilation tube 400 can be ensured, and the aperture consistency of different areas of the ventilation tube 400 is high. In addition, at least part of the area inside the ventilation tube 400 has a capillary effect to prevent the atomized liquid in the liquid storage chamber 110 from leaking due to its own weight, so that the atomized liquid seals the inner cavity of the ventilation tube 400 under the action of liquid adhesion and air pressure. Moreover, when the air pressure in the liquid storage chamber 110 is too low, the external atmosphere can overcome the self-weight and adhesion of the atomized liquid and enter the liquid storage chamber 110 through the ventilation tube 400 to balance the internal air pressure of the liquid storage chamber 110; when the atomizing device is used, the external atmosphere enters the atomizing chamber 220 through the air inlet 310, and enters the liquid storage chamber 110 through the ventilation tube 400 under the action of air pressure, so as to ensure that the internal and external pressure difference allows the atomized liquid to seep more smoothly to the atomizing core 101 and generate an aerosol.

[0052] Furthermore, one end of the ventilation tube 400 facing the liquid storage chamber 110 is flush with the end of the mounting hole 230 facing the liquid storage chamber 110 , and one end of the ventilation tube 400 facing away from the liquid storage chamber 110 exceeds the end of the mounting hole 230 facing away from the liquid storage chamber 110 . In this way, it can be ensured that the air in the atomizing chamber 220 enters the liquid storage chamber 110 for ventilation only through the ventilation tube 400, and the atomized liquid in the liquid storage chamber 110 only enters the ventilation tube 400 and will not contact the inner wall of the mounting hole 230, and the ventilation tube 400 has sufficient length for air circulation to enhance the capillary effect of the ventilation tube 400 and avoid leakage. In addition, when the residual amount of atomized liquid in the liquid storage chamber 110 is small, part of the atomized liquid can be located at the end of the ventilation tube 400 facing the liquid storage chamber 110, thereby realizing liquid sealing of the ventilation tube 400; there is no gradient change in the inner diameter of the ventilation channel in the atomizing device, and the external atmosphere can only be ventilated through the ventilation tube 400, and the atomized liquid in the liquid storage chamber 110 only needs to be liquid-sealed with the ventilation tube 400, thereby avoiding the problem of atomized liquid leakage or poor liquid discharge due to inconsistent inner diameters of the ventilation channel.

[0053] The base 200 has an isolation portion 240. The lower liquid hole 210 is located on the side of the isolation portion 240 facing the liquid storage chamber 110. The atomizing chamber 220 is located on the side of the isolation portion 240 facing away from the liquid storage chamber 110. The atomizing core 101 is mounted on the isolation portion 240 and is at least partially located on the side of the isolation portion 240 facing the atomizing chamber 220. The isolation portion 240 has a liquid guide channel 241, and the atomizing core 101 covers the liquid guide channel 241. The liquid storage tank 100 includes a shell 120 and an air outlet pipe 130. The shell 120 is arranged around the side of the air outlet pipe 130. The inner side of the shell 120 and the outer side of the air outlet pipe 130 define a liquid storage chamber 110. The opposite ends of the air outlet pipe 130 respectively form an air outlet end 131 and an air inlet end 132. The air inlet end 132 is connected to the base 200 and communicates with the atomizing chamber 220. The aerosol in the atomizing chamber 220 enters the air outlet pipe 130 through the air inlet end 132 and is discharged from the air outlet end 131 for inhalation by the user. The end of the liquid storage chamber 110 facing the atomizing chamber 220 is connected to the lower liquid hole 210. The lower liquid hole 210 is annular and converges on the side of the liquid guide channel 241 facing the liquid storage chamber 110. The atomized liquid in the liquid storage chamber 110 seeps through the lower liquid hole 210 to the liquid guide channel 241, and then flows to the atomizing core 101.

[0054] The lower liquid hole 210 and the liquid storage chamber 110 are located on one side of the isolation portion 240, and the atomizing chamber 220 is located on the other side opposite the isolation portion 240. The isolation portion 240 isolates the liquid storage chamber 110 from the atomizing chamber 220, so that the atomized liquid can only flow through the lower liquid hole 210 and the liquid guide channel 241 to the atomizing core 101 for atomization, thereby reducing leakage. The mounting hole 230 is provided on the isolation portion 240 and is located on the side of the liquid guide channel 241 facing away from the atomizer core 101. One end of the ventilation tube 400 is connected to the liquid lowering hole 210, and the other end is connected to the atomizer chamber 220. On the one hand, the ventilation tube 400 is away from the seepage area of the atomized liquid toward the atomizer core 101 and does not affect the liquid lowering of the atomized liquid. On the other hand, the ventilation tube 400 is provided on the isolation portion 240 and does not occupy the area of the base body 200 where the liquid lowering hole 210 is arranged. The base body 200 has a large margin for the liquid lowering hole 210. The liquid lowering hole 210 and the liquid storage chamber 110 have sufficient communication area, so that the liquid storage chamber 110 can be discharged more smoothly.

[0055] Specifically, a mounting groove 242 is provided on the side of the isolation portion 240 facing the atomizing chamber 220, and the mounting groove 242 is communicated with the liquid guide channel 241. The atomizing device also includes a first sealing member 500, which is installed in the mounting groove 242 and clamped between the atomizing core 101 and the isolation portion 240. At least a portion of the atomizing core 101 is located in the mounting groove 242; the interior of the first sealing member 500 is hollow to allow the atomized liquid in the liquid guide channel 241 to seep into the atomizing core 101. The first sealing member 500 seals the gap between the atomizing core 101 and the inner side of the mounting groove 242 and the matching gap between the atomizing core 101 and the liquid guide channel 241, thereby preventing the atomized liquid from seeping from the liquid guide channel 241 into the atomizing chamber 220 and causing leakage.

[0056] Reference Figure 4 and Figure 5 A first receiving portion 320 and a second receiving portion 330 are provided on the side of the base 300 facing the liquid storage chamber 110. The atomization chamber 220 is defined between the first receiving portion 320 and the base 200. The second receiving portion 330 is protruded toward the liquid storage chamber 110 relative to the first receiving portion 320. The air inlet 310 is provided in the second receiving portion 330. Therefore, the air inlet 310 is higher than the first receiving portion 320. After the atomizer core 101 is heated to atomize the atomized liquid to form an aerosol, there is a risk that the aerosol condenses and flows into the atomizer chamber 220, and then flows out from the air inlet 310. In addition, the atomized liquid that seeps into the atomizer core 101 may not be completely atomized and continues to seep into the atomizer chamber 220, thereby causing the atomized liquid to flow out from the air inlet 310. Both the aerosol formed by condensation and the atomized liquid that is not completely atomized will accumulate on the surface of the first receiving portion 320. By setting the air inlet 310 higher than the first receiving portion 320, the resistance of the aerosol or atomized liquid to flow into the air inlet 310 is increased, thereby reducing the risk of the aerosol or atomized liquid flowing out through the air inlet 310.

[0057] It should be noted that, since the second receiving portion 330 is raised compared to the first receiving portion 320 , the air inlet 310 can be closer to the atomizer core 101 . The gas entering the atomizer chamber 220 through the air inlet 310 can quickly drive the aerosol generated by the atomizer core 101 to discharge from the atomizer chamber 220 , and then flow out of the atomizer device from the air outlet end 131 , thereby reducing the aerosol residue in the atomizer chamber 220 and reducing the probability of aerosol condensation in the atomizer chamber 220 .

[0058] In addition, the first receiving portion 320 is connected to the circumferential side of the second receiving portion 330, and the air inlet 310 is located in the central area of the base 300. The air inlet 310 is located directly below the atomizer core 101. The gas entering the atomizer chamber 220 through the air inlet 310 can directly mix with the aerosol near the atomizer core 101 and carry the aerosol out of the atomizer chamber 220, further reducing the residual aerosol in the atomizer chamber 220.

[0059] like Figure 2 and Figure 3 The peripheral wall of the base 200 abuts against the inner wall of the shell 120 of the liquid storage tank 100, and the peripheral wall of the base 200 is provided with a capillary groove 250, which is connected to the atomization chamber 220. The capillary groove 250 is used to accommodate leaked atomized liquid or condensed aerosol to prevent excessive liquid in the atomization chamber 220 from seeping to the outside of the atomization device from the air inlet 310.

[0060] Specifically, the capillary groove 250 is spirally wound around the peripheral wall of the base 200 , or a plurality of capillary grooves 250 are spaced apart along the air inlet direction of the air inlet hole 310 , and adjacent capillary grooves 250 are connected to increase the storage capacity of the capillary groove 250 .

[0061] Reference Figures 4 to 6 The atomizing device further includes a blocking member 600, which is provided with a through hole 610 extending therethrough. The air inlet 310 is connected to the atomizing chamber 220 through the through hole 610. The second receiving portion 330 has a ventilation area 331. The air inlet 310 is arranged in the ventilation area 331. At least part of the projection of the ventilation area 331 along the air inlet direction of the air inlet 310 is located outside the projection of the through hole 610 along the air inlet direction of the air inlet 310; thereby, the blocking member 600 allows external air to enter the atomizing chamber 220 through the air inlet 310 and the through hole 610, and at the same time, the blocking member 600 blocks the ventilation area 331 of the air inlet 310 provided on the second receiving portion 330 to prevent the condensed aerosol on the atomizing core 101 or the leaked atomized liquid from dripping into the air inlet 310, thereby reducing the risk of leakage of the atomizing device.

[0062] Specifically, the air inlet 310 and the through hole 610 are staggered in a plane perpendicular to the air inlet direction. The condensed aerosol or leaked atomized liquid will first be blocked by the area of the enclosure 600 where the through hole 610 is not set, and will not continue to flow downward to the air inlet 310. Even if the condensed aerosol or leaked atomized liquid drops into the through hole 610, since the through hole 610 is staggered from the air inlet 310, the aerosol and the atomized liquid will be blocked by the part of the second receiving part 330 except the ventilation area 331, and will not flow into the air inlet 310.

[0063] Illustratively, a plurality of air inlet holes 310 may be provided, and the plurality of air inlet holes 310 are evenly distributed in the ventilation area 331. On the one hand, the gas entering the atomization chamber 220 through the air inlet holes 310 is more uniform, so that the aerosol in the atomization chamber 220 is brought out of the atomization chamber 220 to a greater extent. On the other hand, the area between adjacent air inlet holes 310 can block condensed aerosol or leaked atomized liquid, further reducing the risk of leakage of the atomization device.

[0064] It should be noted that the enclosure 600 includes an enclosure portion 620, and a through hole 610 is arranged in the enclosure portion 620. The enclosure portion 620 is used to block the ventilation area 331. There is a flow gap 630 between the enclosure portion 620 and the second receiving portion 330. The air inlet 310 and the through hole 610 are connected through the flow gap 630. By setting the flow gap 630, the gas in the air inlet hole 310 in the ventilation area 331 blocked by the enclosure portion 620 can still enter the atomization chamber 220 through the movable gap, which can improve the ventilation volume of the atomization device.

[0065] It can be understood that the through hole 610 is arranged in the central area of the enclosure 620, and the surface of the enclosure 620 located on the outer periphery of the through hole 610 is an arc surface or a slope, so as to guide the condensed aerosol or leaked atomized liquid dripping onto the enclosure 620, so that the aerosol or atomized liquid flows to the first receiving portion 320, thereby reducing the risk of leakage of the atomization device.

[0066] In addition, since the enclosure 600 is arranged on the side of the second receiving portion 330 facing the atomization chamber 220, the enclosure 620 is higher than the second receiving portion 330, and there is a large height difference between the enclosure 620 and the first receiving portion 320, the aerosol accumulated in the atomization chamber 220 or the atomization chamber 220 is more difficult to flow through the through hole 610 to the air inlet 310, thereby reducing the risk of leakage of the atomization device.

[0067] The enclosure 600 further includes a fixing portion 640, which is connected to the circumference of the enclosure 620 and is connected to the base 300 and / or the base 200, so that the enclosure 600 is fixed in the atomizing chamber 220 and maintains a stable position. Exemplarily, the fixing portion 640 is engaged with the first receiving portion 320 to fix the enclosure 600 in the atomizing chamber 220; or, the fixing portion 640 is engaged with the inner wall of the atomizing chamber 220 to fix the enclosure 600 in the atomizing chamber 220; or, a plurality of fixing portions 640 are provided, at least one of which is engaged with the first receiving portion 320, and at least one of which is engaged with the inner wall of the atomizing chamber 220.

[0068] In another embodiment, referring to Figure 7 The fixing portion 640 is clamped between the base 300 and the base 200. The fixing portion 640 is limited by the combination of the base 300 and the base 200 in the air intake direction of the air inlet hole 310 and the circumferential direction of the enclosure portion 620, so that the enclosure portion 600 is firmly fixed in the atomization chamber 220. The structure of the atomization device is simple, and the installation of the enclosure portion 600 is relatively stable.

[0069] Specifically, a limiting groove is provided at the end of the base 200 facing the base 300, and / or a limiting groove is provided on the side of the first receiving portion 320 facing the base 200, and a limiting space 260 is defined between the limiting groove of the base 200 and the first receiving portion 320, or between the limiting groove of the base 200 and the first receiving portion 320, or between the limiting groove of the base 200 and the limiting groove of the first receiving portion 320, and the fixing portion 640 is inserted into the limiting space 260, and the fixing portion 640 is inserted into the limiting space 260 along the air inlet 310. The two sides opposite to each other in the air inlet direction are respectively in contact with the base 200 and the first supporting part 320, and are clamped by the base 200 and the base 300. The side of the fixing part 640 along the circumferential direction of the enclosure part 620 is in contact with the groove wall of the limiting groove. The fixing part 640 is limited in the air inlet direction of the air inlet hole 310 and the circumferential direction of the enclosure part 620 at the same time, preventing the enclosure part 600 from moving along the air inlet direction of the air inlet hole 310 or shaking around the circumference of the enclosure part 620, so that the enclosure part 600 maintains a stable position.

[0070] In addition, refer to Figure 4 and Figure 6 The first receiving portion 320 is provided with a protrusion 321 protruding toward the base 200, and / or, one end of the base 200 facing the base 300 is provided with a protrusion 321 protruding toward the base 300, and the fixing portion 640 is provided with a limiting hole 641, and the limiting hole 641 extends along the air intake direction of the air inlet 310. The protrusion 321 on the first receiving portion 320 and / or the protrusion 321 on the base 200 is inserted into the limiting hole 641, and the protrusion 321 and the hole wall of the limiting hole 641 limit each other, which can prevent the fixing portion 640 from detaching from the limiting space 260, so that the enclosure 600 maintains a stable position.

[0071] The enclosure 600 includes a plurality of fixing portions 640 disposed around the periphery of the enclosure 620 and spaced apart. Each of the fixing portions 640 can be inserted into the limited space 260 defined by the base 200 and the base 300, thereby limiting the enclosure 600 at multiple points and further stabilizing the position of the enclosure 600. In another embodiment, two fixing portions 640 are disposed on opposite sides of the enclosure 620 along a first direction and are inserted into the limited space 260. Furthermore, two fixing portions 640 are disposed on opposite sides of the enclosure 620 along a second direction and are engaged with the first receiving portion 320. The first direction, the second direction, and the air intake direction of the air intake hole 310 are perpendicular to each other.

[0072] Reference Figure 3 and Figure 7The atomizing device further includes an electrode 700. The base 300 is provided with an electrode hole 350. The electrode 700 is inserted into the electrode hole 350, with one end extending into the atomizing chamber 220 and abutting against the surface of the atomizing core 101 facing the base 300, thereby achieving electrical connection with the atomizing core 101. In one embodiment, two electrodes 700 are provided, and a plurality of fixing portions 640 are provided. Two fixing portions 640 are provided on opposite sides of the enclosing portion 620 along the first direction and are both inserted into the limiting space 260. The two fixing portions 640 are provided with a through-hole 642, and an electrode 700 is inserted into the through-hole 642 of each fixing portion 640. The fixing portions 640 can assist the base 300 in stabilizing the position of the electrode 700, thereby effectively connecting the electrode 700 to the atomizing core 101.

[0073] Furthermore, the electrode 700 has a first rod portion 710, a second rod portion 720 and a flange 730. The flange 730 is located between the first rod portion 710 and the second rod portion 720 and protrudes radially relative to the first rod portion 710 and the second rod portion 720. The first rod portion 710 is inserted into the electrode hole 350 of the base 300, and the second rod portion 720 is inserted into the through hole 642 of the fixing portion 640 and abuts against the atomizer core 101. The flange 730 is pressed between the fixing portion 640 and the first receiving portion 320. The electrode 700 is limited by the enclosure 600 and the base 300 in the air intake direction of the air intake hole 310 to maintain a stable position.

[0074] The enclosure portion 620 protrudes back toward the base 300 compared to the fixing portion 640. The fixing portion 640 is arranged around the outer periphery of the second supporting portion 330 and abuts against the peripheral side of the second supporting portion 330. The second supporting portion 330 limits the fixing portion 640 in its own radial direction to improve the installation accuracy of the enclosure 600 and ensure that the enclosure 600 is stably matched with the base 200 and the base 300.

[0075] The base 200 and at least a portion of the base 300 are both mounted within the housing 120 of the liquid storage tank 100. The base 200 and the base 300 are detachably connected to facilitate assembly of the atomizer core 101, the enclosure 600, and the like within the atomizer chamber 220 therebetween. The detachable connection between the base 200 and the base 300 is not limited to snap-fitting or crimping.

[0076] Specifically, refer to Figures 3 to 6 The base 300 includes a first clamping portion 340, which is connected to the first receiving portion 320. The base 200 includes a second clamping portion 270. The first clamping portion 340 is clamped with the second clamping portion 270, so that the atomizing chamber 220 is defined between the first receiving portion 320 of the base 300 and the base 200, and a limiting space 260 is formed for inserting the fixing portion 640. The assembly of the base 300 and the base 200 is relatively convenient.

[0077] Furthermore, the inner wall of the base 200 is provided with a snap-fit groove, which forms a second snap-fit portion 270. The first snap-fit portion 340 is inserted into the base 200 and snap-fits into the snap-fit groove. The groove wall and the first snap-fit portion 340 mutually restrict each other along the circumference of the base 200 and the air intake direction of the air inlet hole 310. The end of the side wall of the base 200 facing the base 300 abuts the base 300, and the second snap-fit portion 270 is clamped between the first snap-fit portion 340 and the housing 120, thereby further stabilizing the assembly structure of the housing 120, base 200, and base 300.

[0078] Reference Figure 1 The atomizing device further includes a bottom shell 800, which covers the end of the housing 120 facing away from the air outlet 131 and provides support for the base 300 toward the base 200. The connection method between the bottom shell 800 and the housing 120 is not limited to magnetic connection, snap connection, etc.

[0079] In addition, a second seal 121 is clamped between the base 300 and the shell 120 of the liquid storage tank 100. The second seal 121 is used to seal the fitting gap between the base 300 and the shell 120 to prevent the atomized liquid or condensed aerosol accumulated in the capillary groove 250 of the base 200 from seeping to the outside of the atomizing device.

[0080] like Figure 1 and Figure 2 As shown, the side of the base 200 facing the liquid storage chamber 110 is also provided with a mist outlet chamber 280 connected to the atomizing chamber 220, and the air inlet end 132 of the air outlet pipe 130 is plugged into the mist outlet chamber 280 and connected to the mist outlet chamber 280. The aerosol formed by atomization in the atomizing chamber 220 is driven by the air flow to flow to the mist outlet chamber 280, and then enters the air outlet pipe 130 through the air inlet end 132, and is finally discharged from the air outlet end 131 for the user to inhale. The cavity wall of the mist outlet chamber 280 is connected to a thorn guide 290 extending toward the air inlet end 132. The thorn guide 290 is used to puncture the droplets or bubbles that reflux in the air outlet pipe 130 to prevent the droplets or bubbles from flowing out of the air outlet end 131 when the user inhales, affecting the user experience.

[0081] Furthermore, the thorn guide 290 can be partially inserted into the air inlet end 132 of the air inlet tube, or the thorn guide 290 can be completely contained within the mist outlet chamber 280. The end of the thorn guide 290 facing the air outlet end 131 is sharpened to more easily puncture droplets or bubbles. The thorn guide 290 is tilted relative to the extension direction of the air outlet tube 130, and the end of the thorn guide 290 facing the air outlet end 131 avoids the central area of the air outlet end 131 to minimize the impact of the thorn guide 290 on the airflow entering the mist outlet chamber 280 and from the mist outlet chamber 280 into the air outlet tube 130.

[0082] Reference Figure 1As shown in Figure 3, the atomizing device further includes a third seal 900, which is located at the end of the base 200 facing away from the base 300. Part of the third seal 900 is clamped between the outer wall of the base 200 and the inner wall of the housing 120. Part of the third seal 900 is inserted into the mist outlet chamber 280 and clamped between the outer wall of the air outlet pipe 130 and the inner wall of the mist outlet chamber 280. The third seal 900 can achieve a seal at the junction of the inner wall of the mist outlet chamber 280 and the air outlet pipe 130, preventing the atomized liquid in the liquid storage chamber 110 from seeping into the mist outlet chamber 280.
