[0053] This application discloses an aerosol generating device, which includes an atomizing device and a power supply device connected to the atomizing device. The aerosol generating device is used to heat and atomize an atomizing liquid (or aerosol generating matrix) into an aerosol for consumer use.

[0054] The aerosol generating device may include, but is not limited to, electronic cigarettes, atomizing beauty devices, or atomizing medical devices, and the atomizing liquid may include, but is not limited to, e-liquid or medicinal liquid. When the aerosol generating device is an electronic cigarette, the atomizing device may include, but is not limited to, a cartridge, and the power supply device may include, but is not limited to, a cigarette holder.

[0055] See Figures 1 to 3 This utility model discloses an atomizing device, which includes a housing assembly 10 and an atomizing component 20 installed within the housing assembly 10. The housing assembly 10 has an air inlet and an air outlet, and also has a liquid storage chamber 10a (e.g., Figure 2 (As shown).

[0056] The atomizing assembly 20 includes an atomizing bracket 21 and an atomizing core 22 installed within the atomizing bracket 21. The atomizing bracket 21 has a tubular structure, and its inner cavity is connected to the air inlet and air outlet of the outer casing assembly 10. The atomizing bracket 21 has a plurality of liquid inlet holes 211 penetrating its inner and outer walls and a plurality of ventilation gaps 212. The liquid inlet holes 211 can be circular, square, diamond-shaped, or other shaped holes, and no specific limitation is made here.

[0057] The atomizing core 22 includes a liquid guide 221 and a heating element 222 that cooperate with each other. The liquid guide 221 is arranged opposite to the liquid inlet 211. The atomizing liquid in the liquid storage chamber 10a is introduced into the liquid guide 221 through the liquid inlet 211. The liquid guide 221 partially blocks the ventilation gap 212 in the axial direction.

[0058] The outer casing assembly 10 includes a base 11, which has a mounting groove 111 for the lower end of the atomizing bracket 21 to be inserted and fixed. The inner wall of the mounting groove 111 partially blocks the ventilation gap 212 on the axis. Alternatively, the atomizing device also includes a shielding member 30, which is used to fit around the outer periphery of the atomizing bracket 21 and partially blocks the ventilation gap 212 on the axis. The shielding member 30 may be installed in the mounting groove 111, such as with its lower end installed in the mounting groove 111. In some embodiments, the outer casing assembly 10 also includes a mounting seat, which can be connected to the base 11, and the shielding member 30 can be installed on the mounting seat. That is, the shielding member 30 is not limited to being installed on the base 11. Of course, the outer casing assembly 10 may also include other mounting structures for the installation of the shielding member 30, which are not specifically limited here.

[0059] The inner cavity of the atomizing bracket 21 is connected to the ventilation gap 212, allowing some of the gas in the atomizing bracket 21 to enter the liquid storage chamber 10a through the ventilation gap 212. In addition, some of the gas in the liquid storage chamber 10a can also enter the inner cavity of the atomizing bracket 21 through the ventilation gap 212. This balances the air pressure in the liquid storage chamber 10a, allowing the atomized liquid in the liquid storage chamber 10a to flow more smoothly into the guide liquid 221, preventing the atomizing core 22 from burning dry, ensuring sufficient atomization, effectively protecting the user experience, and improving product competitiveness.

[0060] Furthermore, the liquid guide 221 partially blocks the ventilation gap 212 in the axial direction, the inner wall of the mounting groove 111 partially blocks the ventilation gap 212 in the axial direction, or the blocking member 30 can partially block the ventilation gap 212 in the axial direction, which can prevent the atomized liquid in the liquid storage chamber 10a from entering the inner cavity of the atomizing bracket 21. Moreover, due to capillary action, the small amount of atomized liquid that enters the ventilation gap 212 will not seep into the inner cavity of the atomizing bracket 21, thus avoiding the problem of oil leakage.

[0061] Combination Figure 4 and Figure 5 As shown, in some embodiments, the plane containing the upper surface of the mounting groove 111 is located above the plane containing the lower end face of the liquid guide 221 in the height direction. Even if a small amount of atomized liquid in the liquid storage chamber 10a enters the ventilation gap 212, it can be easily absorbed by the liquid guide 221. In addition, the mounting groove 111 can also act as an isolation device to ensure that the atomized liquid in the liquid storage chamber 10a does not enter the inner cavity of the atomizing bracket 21.

[0062] In some embodiments, the ventilation gap 212 and the liquid inlet 211 are isolated on the atomizing bracket 21, that is, the ventilation gap 212 and the liquid inlet 211 are not connected. Figures 6 to 13 In the first to fourth embodiments, the ventilation gap 212 of the atomizing bracket 21 is isolated from the liquid inlet 211, and the two are not connected.

[0063] In some embodiments, the ventilation gap 212 is connected to and communicates with the liquid inlet 211. For example... Figures 14 to 15 In the fifth embodiment, the ventilation gap 212 of the atomizing bracket 21 is connected and interconnected with the liquid inlet 211.

[0064] In some embodiments, the uppermost end of the ventilation gap 212 is located between the uppermost and lowermost ends of the liquid inlet 211. For example... Figures 6 to 13In the first to fourth embodiments, the uppermost end of the ventilation gap 212 of the atomizing bracket 21 is located between the uppermost and lowermost ends of the liquid inlet 211. When the liquid guide 221 completely blocks the liquid inlet 211, it can also block part of the structure of the ventilation gap 212. When there are multiple liquid inlets 211, the multiple liquid inlets 211 can be arranged at intervals along the axial and / or circumferential direction of the atomizing bracket 21. Then, the uppermost end of the ventilation gap 212 is located between the uppermost and lowermost ends of a portion of the liquid inlet 211. For example, the uppermost end of the ventilation gap 212 is located between the uppermost and lowermost ends of a portion of the liquid inlet 211 near the lower end of the atomizing bracket 21.

[0065] In some embodiments, such as Figure 10 and Figure 11 As shown, there are one or more ventilation gaps 212, each of which is elongated and extends along the axial direction of the atomizing bracket 21. The ventilation gap 212 is approximately rectangular in shape on a plane. Figure 11 As shown. Adjacent ventilation gaps 212 are arranged in parallel at intervals.

[0066] In some embodiments, such as Figures 6 to 9 As shown, the ventilation gap 212 is generally Y-shaped. The ventilation gap 212 includes a main body 2121, which is arc-shaped, C-shaped or U-shaped. The ventilation gap 212 also includes a long strip 2122 that is connected to the middle of the main body 2121 and extends along the axial direction of the atomizing bracket 21.

[0067] In some embodiments, such as Figure 12 and Figure 13 As shown, the ventilation gap 212 includes a first vertical portion 2123, a second vertical portion 2124, and a horizontal portion 2125. The first vertical portion 2123 and the second vertical portion 2124 are arranged parallel to each other and spaced apart. The horizontal portion 2125 connects the lower end of the first vertical portion 2123 and the upper end of the second vertical portion 2124. Here, the second vertical portion 2124 extends towards the lower end of the atomizing bracket 21. The first vertical portion 2123, the second vertical portion 2124, and the horizontal portion 2125 are approximately rectangular in shape on the plane.

[0068] In some embodiments, such as Figure 14 and Figure 15 As shown, the ventilation gap 212 may be connected to the lowest end of the liquid inlet 211, and the ventilation gap 212 extends toward the lower end of the atomizing bracket 21.

[0069] In some embodiments, the lower end of the ventilation gap 212 may extend to the lower end of the atomizing bracket 21, or the lower end of the ventilation gap 212 may be spaced apart from the lower end of the atomizing bracket 21. No specific limitations are specified here.

[0070] Of course, the ventilation gap 212 can also be other structural shapes, which are not specifically limited here.

[0071] In some embodiments, atomizing bracket 21 may be provided with multiple ventilation gaps 212. The shapes of the ventilation gaps 212 may be the same or different. For example, the ventilation gaps 212 on atomizing bracket 21 may all be the ventilation gaps 212 of the first embodiment. Of course, the ventilation gaps 212 on atomizing bracket 21 may be the ventilation gaps 212 of the first embodiment and the second embodiment. That is, the setting style and number of ventilation gaps 212 on atomizing bracket 21 can be selected according to actual needs, and no specific limitation is made here.

[0072] In some embodiments, the atomizing bracket 21 may be a generally circular tubular structure. Of course, the cross-sectional shape of the atomizing bracket 21 may also be square or elliptical, without specific limitations. The atomizing bracket 21 may be made of metal materials, such as stainless steel or aluminum alloy. Of course, the atomizing bracket 21 may also be made of composite materials, without specific limitations.

[0073] In some embodiments, the wall thickness of the atomizing bracket 21 is 0.1mm-1mm. For example, the wall thickness of the atomizing bracket 21 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm. The wall thickness of the atomizing bracket 21 can be selected and set according to actual needs, and no specific limitation is made here.

[0074] In some embodiments, the width of the ventilation gap 212 is 0.1mm-1mm. The width of the ventilation gap 212 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm. The width of the ventilation gap 212 can be selected and set according to actual needs, and no specific limitation is made here.

[0075] like Figures 16 to 24 As shown, in some embodiments, the atomizing device further includes a shielding member 30, which is fitted around the outer periphery of the atomizing bracket 21 and partially blocks the ventilation gap 212 on the axis. At least a portion of the structure of the shielding member 30 (such as the lower end of the shielding member 30) can be inserted into the mounting groove 111 of the base 11.

[0076] like Figures 16 to 21 As shown, in the sixth and seventh embodiments, the shielding member 30 is tubular, such as a cylindrical tube. The inner diameter of the shielding member 30 can be the same as or similar to the outer diameter of the atomizing bracket 21. The axial length of the shielding member 30 is similar to the axial length of the atomizing bracket 21; for example, the axial length of the shielding member 30 is the same as the axial length of the atomizing bracket 21, or the axial length of the shielding member 30 is a few millimeters less than the axial length of the atomizing bracket 21. Preferably, as shown... Figure 18 As shown, the upper end of the atomizing bracket 21 may also be provided with a ventilation channel 213. The shape and width of the ventilation channel 213 may be the same as or similar to the ventilation gap 212, and no specific limitation is made here. Of course, the ventilation channel 213 may not be provided.

[0077] The shielding member 30 is provided with a liquid guiding hole 31 that penetrates its inner and outer walls. The liquid guiding hole 31 is connected to the liquid inlet hole 211 and is also connected to a part of the structure of the ventilation gap 212.

[0079] For example Figures 2 to 3 As shown, the housing assembly 10 also includes a mounting shell 12 and a top cover 13. The mounting shell 12 is tubular, such as a cylindrical tube, and has an axial upper end and a lower end. The top cover 13 is mounted on the upper end of the mounting shell 12, and the base 11 is mounted on the lower end of the mounting shell 12.

[0080] The top cover 13 may include a columnar cover body 131.

The outer circumferential wall of the cover body 131 may also be provided with a number of first protrusions to improve the sealing performance.

[0081] The base 11 can be generally cylindrical. The base 11 can be an interference fit, threaded connection, or snap-fit ​​connection of the lower end inner cavity of the mounting shell 12. The outer circumferential wall of the base 11 can also be provided with several second protrusions to improve the sealing performance.

[0082] The upper end of the atomizing bracket 21 is connected to the upper cover 13. For example, the bottom wall of the cover body 131 of the upper cover 13 is provided with an insertion groove, and the upper end of the atomizing bracket 21 is inserted into the insertion groove.

[0083] The top cover 13 is provided with a mouthpiece portion 132 that communicates with the inner cavity of the atomizing bracket 21. The mouthpiece portion 132 is provided on the cover body 131 and forms the air outlet. The mouthpiece portion 132 is generally cylindrical, and the inner diameter of the inner cavity of the mouthpiece portion 132 gradually increases from bottom to top, so that when the aerosol is discharged from the mouthpiece portion 132, the inner cavity of the mouthpiece portion 132 can be appropriately cooled.

[0084] Furthermore, the upper surface of the base 11, the inner wall of the mounting shell 12, the outer surface of the atomizing bracket 21, and the inner bottom surface of the top cover 13 define the liquid storage chamber 10a.
