DETAILED DESCRIPTION

[0037] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, not all of the embodiments. Based on the embodiments provided in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present application.

[0038] Mentioning "embodiment" in this application means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of this application, and the appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent or alternative embodiment with other embodiments. It can be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0039] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example: a component or device including one or more parts is not limited to the one or more parts listed, but optionally includes one or more parts that are not listed but inherent to the exemplified product, or one or more parts that it should have based on the described function.

[0040] In general technology, when the electronic atomizer is heating the e-liquid to generate steam, if the heating temperature is too high, the temperature of the smoke will rise. After the smoke enters the mouth through the filter, the smoke will feel hot when entering the mouth.

[0041] An embodiment of the present application provides an atomization device 100 for improving the cooling effect of smoke.

[0042] See also Figure 1 and Figure 2 The atomizing device 100 includes a housing 10 , a heating component 20 and a flow guide 30 .

[0043] This embodiment does not specifically limit the structure of the housing 10. Optionally, the housing 10 is in the shape of a hollow round rod.

[0044] See also Figure 3 The inner chamber of the shell 10 includes a heating chamber 101, a guide chamber 102 and a cooling chamber 103 which are arranged in sequence along the axial direction X.

[0045] Optional, see Figure 2 and Figure 3 The atomizing device 100 further includes a plug 40 , which is sealed at one end of the heating chamber 101 of the housing 10 away from the flow guiding chamber 102 .

[0046] Optional, see Figure 2 and Figure 3 The atomizing device 100 further includes a filter 50 , which is mounted on an end of the cooling chamber 103 of the housing 10 away from the heating chamber 101 . The filter 50 is in communication with the cooling chamber 103 .

[0047] See also Figure 2 and Figure 3 The heating chamber 101 stores an atomizing medium 300. The atomizing medium 300 is an aerosol substrate. Optionally, the atomizing medium 300 includes but is not limited to tobacco.

[0048] The heating component 20 is disposed in the heating chamber 101. The heating component 20 is used to heat the atomized medium 300 stored in the heating chamber 101, so that the atomized medium 300 is gasified to form aerosol (ie, smoke).

[0049] The present application does not impose any specific limitation on the material and heating method of the heating component 20 .

[0050] Under the suction force of the filter 50 , smoke flows from the heating component 20 to the cooling chamber 103 through the guide chamber 102 .

[0051] In an optional embodiment, the cooling chamber 103 is an air chamber. When the smoke passes through the cooling chamber 103 and reaches the filter 50, the smoke exchanges heat with the air in the cooling chamber 103, thereby reducing the temperature of the smoke. In addition, the air in the cooling chamber 103 can dilute the concentration of the smoke and also have the effect of reducing the temperature of the smoke.

[0052] In other embodiments, the cooling chamber 103 further includes a packaged refrigerant medium or a heat sink, etc., which exchanges heat with the smoke to reduce the temperature of the smoke.

[0053] In addition to the above designs, the present application also sets a deflector 30 in the deflection chamber 102. The deflector 30 can guide the direction of smoke movement and achieve a cooling effect. The deflector 30 provided in the embodiment of the present application is described below with reference to the accompanying drawings.

[0054] The deflector 30 is disposed in the deflector chamber 102 of the housing 10 .

[0055] Optionally, the deflector 30 is detachably connected to the deflector chamber 102 of the housing 10. The deflector 30 is an independent structural member. When the deflector 30 is disposed in the deflector chamber 102 of the housing 10, the outer peripheral wall of the deflector 30 can be assembled in the deflector chamber 102 of the housing 10 through friction fit, interference fit, etc. with the inner peripheral wall of the housing 10.

[0056] In this embodiment, the deflector 30 is detachably connected to the deflector chamber 102 of the housing 10 , so that the deflector 30 can be replaced after being used for a long time or when the deflector 30 is blocked.

[0057] Alternatively, the deflector 30 may be integrally formed with the housing 10 . In other words, when preparing the housing 10 , a plurality of deflector channels are formed in a middle section inside the housing 10 to form the deflector 30 .

[0058] See also Figure 4The deflector 30 includes at least one deflection channel 30a. The deflection channels 30a are all arranged along the axial direction X of the housing 10. The axial direction X of the housing 10 is the length direction of the housing 10.

[0059] One end of the guide channel 30 a is connected to the heating chamber 101 , and the other end of the guide channel 30 a is connected to the cooling chamber 103 .

[0060] In this embodiment, the guide channel 30a is arranged along the axial direction X to guide the aerosol generated in the heating chamber 101 to the cooling chamber 103. The guide channel 30a is along the suction direction of the filter 50, so that the aerosol airway formed by the guide channel 30a is smooth, and the operator can inhale more easily.

[0061] See also Figure 5 The guide channel 30a includes a first guide section 301, a second guide section 302 and a third guide section 303 which are sequentially arranged along the axial direction X.

[0062] The radial dimension of the second guide section 302 is smaller than the radial dimension of the first guide section 301. The radial dimension of the second guide section 302 is smaller than the radial dimension of the third guide section 303. In other words, the guide channel 30a is a flow channel that is narrow in the middle and wide at both ends. The radial direction is a direction perpendicular to the axial X plane.

[0063] The first flow guiding section 301 is adjacent to and communicates with the heating chamber 101. The third flow guiding section 303 is adjacent to and communicates with the heating chamber 101.

[0064] The first guide section 301, the second guide section 302 and the third guide section 303 are used to sequentially guide the heated atomized medium 300 in the heating chamber 101 to the cooling chamber 103. In other words, under the suction force of the filter 50, the heated atomized medium 300 in the heating chamber 101 forms an aerosol, and the aerosol flows into the cooling chamber 103 after passing through the first guide section 301, the second guide section 302 and the third guide section 303 in sequence.

[0065] In the process of aerosol flowing from the first guide section 301 with a large radial size to the second guide section 302 with a small radial size, according to the Venturi principle, the first guide section 301 is a positive pressure section compared to the second guide section 302, and the second guide section 302 is a negative pressure section compared to the first guide section 301. The negative pressure section forms suction on the positive pressure section, so the aerosol can quickly flow from the first guide section 301 with a large radial size to the second guide section 302 with a small radial size, so as to speed up the flow of aerosol from the first guide section 301 to the second guide section 302, so that the operator can more easily draw the aerosol from the heating chamber 101 to the cooling chamber 103, and the operator can save effort and be smoother when drawing the aerosol, and the operator can draw more easily.

[0066] Since the radial dimension of the third guide section 303 is greater than the radial dimension of the second guide section 302, the aerosol expands and cools down when flowing from the second guide section 302 to the third guide section 303, and the aerosol discharged through the third guide section 303 exchanges heat with the relatively low temperature air in the cooling chamber 103, further cooling the atomized smoke to reduce the problem of the atomized smoke burning the mouth.

[0067] The present application does not impose any specific limitation on the material of the deflector 30 .

[0068] Optionally, the deflector 30 is made of a high temperature resistant material to withstand the aerosol flowing out of the heating chamber 101 .

[0069] The material of the deflector 30 includes but is not limited to high temperature resistant materials such as polyphenylene sulfide (PPS) and polylactic acid (PLA).

[0070] The present application provides an atomization device 100, comprising a housing 10, a heating assembly 20 and a deflector 30, wherein the housing 10 comprises a heating chamber 101, a deflector chamber 102 and a cooling chamber 103 arranged in sequence along an axial direction X; the heating assembly 20 is arranged in the heating chamber 101, and the heating assembly 20 is used to heat the atomization medium 300 stored in the heating chamber 101; the deflector 30 is arranged in the deflector chamber 102, and the deflector 30 comprises at least one deflection channel 30a, and the deflection channel 30a comprises a first deflection section 301, a second deflection section 302 and a third deflection section 303 arranged in sequence along the axial direction X, the radial dimension of the second deflection section 302 is smaller than the radial dimension of the first deflection section 301, the radial dimension of the second deflection section 302 is smaller than the radial dimension of the third deflection section 303, and the first deflection section 301 is adjacent to and communicated with the heating chamber 101, The first guide section 301, the second guide section 302 and the third guide section 303 are used to guide the heated atomized medium 300 to the cooling chamber 103 in sequence; the atomized medium 300 forms an aerosol after heating, and in the process of the aerosol flowing from the first guide section 301 with a large radial size to the second guide section 302 with a small radial size, the first guide section 301 is a positive pressure section compared to the second guide section 302, and the second guide section 302 is a positive pressure section compared to the second guide section 302. The first guide section 301 is a negative pressure section to accelerate the flow of aerosol from the first guide section 301 to the second guide section 302; since the radial dimension of the third guide section 303 is larger than the radial dimension of the second guide section 302, the aerosol expands and cools down when flowing from the second guide section 302 to the third guide section 303, and the aerosol discharged through the third guide section 303 exchanges heat with the relatively low temperature air in the cooling chamber 103, further cooling the atomized smoke.

[0071] Optionally, a radial dimension of the first guide section 301 gradually decreases along a direction from the heating chamber 101 to the cooling chamber 103 .

[0072] For the convenience of description, the direction from the heating chamber 101 to the cooling chamber 103 is defined as the first direction X1. The radial dimension of the first guide segment 301 gradually decreases along the first direction X1.

[0073] See also Figure 5Specifically, the first guide section 301 is roughly trumpet-shaped. The opening of the first guide section 301 toward the heating chamber 101 is the first opening 304, and the opening of the first guide section 301 toward the second guide section 302 is the second opening 305. The shape of the first opening 304 includes but is not limited to a circle, a rectangle, a triangle, a polygon, an irregular shape, etc. In this embodiment, the first opening 304 is circular as an example. The shape of the second opening 305 is but is not limited to a circle, a rectangle, a triangle, a polygon, an irregular shape, etc. In this embodiment, the second opening 305 is circular as an example.

[0074] The second opening 305 is directly opposite to the center of the first opening 304 , and the diameter of the second opening 305 is smaller than the diameter of the first opening 304 .

[0075] Optionally, the central axis of the first guide segment 301 is the central axis of the guide device 30 or is parallel to the central axis of the guide device 30 .

[0076] Optionally, a radial dimension of the third guide section 303 gradually increases along a direction from the heating chamber 101 to the cooling chamber 103 .

[0077] See also Figure 5 Specifically, the third guide section 303 is roughly trumpet-shaped. The opening of the third guide section 303 toward the cooling chamber 103 is the fourth opening 307, and the opening of the third guide section 303 toward the second guide section 302 is the third opening 306. The shape of the third opening 306 includes but is not limited to a circle, a rectangle, a triangle, a polygon, an irregular shape, etc. In this embodiment, the third opening 306 is circular as an example. The shape of the fourth opening 307 is but is not limited to a circle, a rectangle, a triangle, a polygon, an irregular shape, etc. In this embodiment, the fourth opening 307 is circular as an example.

[0078] The third opening 306 is directly opposite to the center of the fourth opening 307 , and the diameter of the third opening 306 is smaller than the diameter of the fourth opening 307 .

[0079] Optionally, the central axis of the third guide segment 303 is the central axis of the guide 30 or is parallel to the central axis of the guide 30. In other words, the central axis of the third guide segment 303 and the central axis of the first guide segment 301 are collinear.

[0080] The diameter of the fourth opening 307 may be greater than, less than, or equal to the diameter of the first opening 304. In this embodiment, the diameter of the fourth opening 307 is equal to the diameter of the first opening 304 as an example.

[0081] The diameter of the third opening 306 may be greater than, less than, or equal to the diameter of the second opening 305. In this embodiment, the diameter of the third opening 306 is equal to the diameter of the second opening 305. In other words, the second guide section 302 is cylindrical. Optionally, the central axis of the first guide section 301, the central axis of the second guide section 302, and the central axis of the third guide section 303 are collinear, and the central axis of the second guide section 302 is the axial direction X of the shell 10. The negative pressure section formed from the first guide section 301 to the second guide section 302 accelerates the flow of the aerosol from the heating chamber 101 through the first guide section 301 to the second guide section 302. The second guide section 302 guides the flow direction of the aerosol so that the aerosol flows along the axial direction X of the shell, that is, the suction direction. The third guide section 303 is used for aerosol expansion and cooling, and the cooling chamber 103 is used for further expansion and cooling of the aerosol in the third guide section 303 and heat exchange with air at a lower temperature, so as to further achieve cooling of the aerosol.

[0082] In a first alternative implementation, see Figure 6 The flow guide channel 30a includes a first flow guide channel 31. The first flow guide channel 31 is located at the center of the flow guide 30. The first flow guide channel 31 penetrates the flow guide 30 along the axial direction X. In other words, the central axis of the first flow guide channel 31 is colinear with the central axis of the flow guide 30.

[0083] Specifically, the center of the flow guide 30 has a first flow guide channel 31. The first flow guide channel 31 can refer to the first flow guide section 301, the second flow guide section 302 and the third flow guide section 303 mentioned above.

[0084] See also Figure 6 From the cross section of the first guide channel 31 along the central axis, the cross-sectional line of the inner wall of the first guide channel 31 includes a first straight wall 311, a first curved wall 312, a first inclined wall 313, a second curved wall 314, a second straight wall 315, a third curved wall 316, a second inclined wall 317, a fourth curved wall 318 and a third straight wall 319 in sequence along the first direction X1.

[0085] The first straight wall 311 is parallel to the axial direction X of the deflector 30. The first straight wall 311 introduces the aerosol in the heating chamber 101 into the first guide channel 31 along the axial direction X. The first curved wall 312 is an inner concave curved surface. The channel aperture at the corresponding position of the first curved wall 312 gradually converges. The first curved wall 312 is an inner concave curved surface to reduce the airflow resistance and improve the airflow smoothness. The first inclined wall 313 is inclined toward the central axis to guide the airflow toward the central axis. The second curved wall 314 is an outer convex curved surface. To guide the airflow into the second guide channel 30a; the second straight wall 315 is parallel to the axial direction X, so as to guide the airflow to the axial direction X along the outer shell 10; the third curved wall 316 is an outward convex arc, so as to gradually guide the airflow in the second guide channel 30a to the third guide channel 30a with a larger aperture; the second inclined wall 317 is inclined gradually away from the central axis, so as to guide the airflow to the outward-expanding third guide section 303; the fourth curved wall 318 is an inward concave arc surface, so as to guide the airflow to the flow channel with a larger radial dimension.

[0086] Optionally, the present application does not specifically limit the division of the first guide section 301, the second guide section 302, and the third guide section 303. In an optional embodiment, the second guide section 302 is the flow channel portion corresponding to the second straight wall 315, the first guide section 301 is the flow channel portion corresponding to the first straight wall 311, the first curved wall 312, the first inclined wall 313, and the second curved wall 314, and the third guide section 303 is the flow channel portion corresponding to the third curved wall 316, the second inclined wall 317, the fourth curved wall 318, and the third straight wall 319.

[0087] In this implementation, please refer to Figure 7 The deflector 30 further includes a first sub-channel 331, one end of which penetrates the surface of the deflector 30 facing the cooling chamber 103. The other end of the first sub-channel 331 penetrates the inner wall of the second guide section 302. The first sub-channel 331 conducts the cooling chamber 103 and the second guide section 302. Since the second guide section 302 is at a relatively negative pressure, part of the relatively low-temperature air in the cooling chamber 103 will flow to the second guide section 302 through the first sub-channel 331 to cool the aerosol in the second guide section 302.

The second sub-channel 332 connects the cooling chamber 103 and the narrow guide section of the second guide channel 32. Since the narrow guide section of the second guide channel 32 is a relatively negative pressure, part of the relatively low-temperature air in the cooling chamber 103 will flow to the narrow guide section of the second guide channel 32 through the second sub-channel 332 to cool the aerosol in the narrow guide section of the second guide channel 32.

[0103] Optionally, the central axis of the first sub-guiding groove 341 is parallel to the central axis of the guide device 30 .

[0104] The size of the first sub-guiding groove 341 in the axial direction X also gradually decreases along the first direction X1. In other words, the size of the first notch 344 in the axial direction X is smaller than the size of the second notch 345 in the axial direction X.

[0105] The circumferential size of the first sub-guiding groove 341 also gradually decreases along the first direction X1. In other words, the circumferential size of the first notch 344 is smaller than the circumferential size of the second notch 345.

[0106] Optionally, the dimension of the third sub-guiding groove 343 in the direction around the central axis of the guide device 30 gradually decreases and increases from the heating chamber 101 to the cooling chamber 103 .

The shape of the third notch 346 includes but is not limited to a circle, a rectangle, a triangle, a polygon, an irregular shape, etc. In this embodiment, the third notch 346 is circular as an example. The shape of the fourth notch 347 is but is not limited to a circle, a rectangle, a triangle, a polygon, an irregular shape, etc. In this embodiment, the fourth notch 347 is circular as an example.

[0111] The radial dimension of the third notch 346 may be greater than, less than, or equal to the radial dimension of the second notch 345. In this embodiment, the radial dimension of the third notch 346 is equal to the radial dimension of the second notch 345 as an example.

The negative pressure section formed by the first sub-guide groove 341 to the second sub-guide groove 342 accelerates the flow of the aerosol from the heating chamber 101 through the first sub-guide groove 341 to the second sub-guide groove 342. The second sub-guide groove 342 guides the flow direction of the aerosol so that the aerosol flows along the axial direction X of the shell, that is, the suction direction. The third sub-guiding groove 343 is used for aerosol expansion and cooling, and the cooling chamber 103 is used for further expansion and cooling of the aerosol in the third sub-guiding groove 343 and heat exchange with air at a lower temperature, so as to further achieve cooling of the aerosol.

[0112] The size of the third sub-guiding groove 343 in the axial direction X also gradually increases along the first direction X1. In other words, the size of the third notch 346 in the axial direction X is smaller than the size of the fourth notch 347 in the axial direction X.

[0113] The circumferential size of the third sub-guiding groove 343 also gradually increases along the first direction X1. In other words, the circumferential size of the third notch 346 is smaller than the circumferential size of the fourth notch 347.

[0114] Optional, see Fig.14 The guide groove 34 includes a first side groove wall 351, a bottom groove wall 352 and a second side groove wall 353, all of which are extended along the axial direction X. The first side groove wall 351 and the second side groove wall 353 are respectively connected to opposite sides of the bottom groove wall 352. The first side groove wall 351, the bottom groove wall 352 and the second side groove wall 353, and the inner side wall of the housing 10 surround and form the second guide channel 32.

[0115] See also Fig.14 The first side groove wall 351 includes a convergent portion 3511, a middle portion 3512 and an outward expansion portion 3513 connected in sequence along the first direction X1. The convergent portion 3511 gradually approaches the central axis of the guide groove 34 in the first direction X1; and the convergent portion 3511 gradually extends in a direction away from the second side groove wall 353 from the inside to the outside in a radial direction.

[0117] The outward expansion portion 3513 gradually moves away from the central axis of the guide groove 34 in the first direction X1; and the convergent portion 3511 gradually extends in a direction away from the second side groove wall 353 from the inside to the outside in a radial direction.

[0118] The second side groove wall 353 and the first side groove wall 351 are two side groove walls symmetrically arranged.

[0119] See also Fig.12 and Fig.14 The bottom groove wall 352 includes a first sub-bottom groove wall 3521, a second sub-bottom groove wall 3522, and a third sub-bottom groove wall 3523 that are sequentially connected along the axial direction X.

The bottom groove wall 352 gradually moves away from the central axis of the deflector 30 along the first direction X1. The distance between the second sub-bottom groove wall 3522 and the central axis of the deflector 30 along the first direction X1 can be approximately constant. The distance between the third sub-bottom groove wall 3523 and the central axis of the deflector 30 along the first direction X1 can gradually decrease.

[0121] In this embodiment, the second guide channel 32 of the guide device 30 is designed so that the first guide groove 34 forms a gradually converging airflow channel, thereby accelerating the aerosol to flow from the first guide groove 34 to the second guide groove 34. In addition, the aerosol forms an airflow direction in the second guide groove 34 along the axial direction X of the housing 10, which is also the suction direction. In the process of the aerosol flowing from the second guide groove 34 to the third guide groove 34, on the one hand, the aerosol expands and cools down, and on the other hand, heat exchange and cooling are performed with the air in the cooling chamber 103 to enhance the cooling effect of the smoke.

[0122] A guide protrusion is disposed between two adjacent second guide grooves 34 . The guide protrusion protrudes toward the side where the housing 10 is located, and at least a portion of the guide protrusion abuts against the inner wall of the housing 10 .

[0123] The present application does not make any specific limitation on the outer contour structure of the deflector 30 . Optionally, the outer contour of the deflector 30 includes but is not limited to a cylindrical shape, a square shape, etc.

[0124] The present application does not make any specific limitation on the heating component 20. The structure of the heating component 20 is described below by way of example.

[0125] Optional, see Fig.15 The heating component 20 is tubular. The central axis of the heating component 20 and the central axis of the housing 10 may be collinear.

[0127] See also Fig.15 The chamber surrounded and formed between the outer circumferential wall of the heating component 20 and the inner circumferential wall of the housing 10 is the second chamber 202. Optionally, the second chamber 202 is cylindrical.

[0128] In other words, the heating assembly 20 divides the heating chamber 101 into an inner first chamber 201 and an outer second chamber 202 .

[0129] The first chamber 201 is used to store a first atomized medium 310. The second chamber 202 is used to store a second atomized medium 320. The first atomized medium 310 and the second atomized medium 320 can be the same medium or different mediums.

[0130] The inner wall of the heating component 20 can heat the first atomizing medium 310 , and the outer wall of the heating component 20 can heat the second atomizing medium 320 , thereby increasing the heating area of ​​the heating component 20 and improving the heating uniformity.

[0131] In general technology, when the internal heating metal of the electronic atomizer heats the atomizing medium 300, the heating area is small and the heating is not uniform, so the atomizing medium 300 cannot be quickly heated, the smoke is slow, the smoke is small, and the taste is poor. In addition, due to the uneven heating, the host needs to heat at high power for a long time, which is inefficient and energy-consuming.

[0132] In the present application, the heating component 20 is designed to be tubular, and the inner wall of the heating component 20 can heat the first atomizing medium 310, and the outer wall of the heating component 20 can heat the second atomizing medium 320, thereby increasing the heating area of ​​the heating component 20, improving the heating uniformity, and also improving the heating uniformity of the atomizing medium 300, so that the smoke emission effect is good, the main unit does not need to be heated at high power for a long time, and the energy consumption is relatively small.

[0133] Optionally, the first chamber 201 is connected to the first guide channel 31. The second chamber 202 is connected to at least one of the second guide channels 32. The first aerosol formed by heating the atomizing medium 300 in the first chamber 201 flows out through the first guide channel 31. The second aerosol formed by heating the atomizing medium 300 in the second chamber 202 flows out through multiple first guide channels 31. On the one hand, the heating area of ​​the atomizing medium 300 is increased, the smoke output effect is improved, and the fluency of smoke output is increased, and the ease of inhalation is improved; in the process of smoke output, the smoke is physically cooled to solve the pain point of burning the mouth during the inhalation process.

[0134] Optionally, the opening of the first guide channel 31 toward the heating chamber 101 has a diameter greater than or equal to a diameter of the first chamber 201 , so that the first aerosol formed in the first chamber 201 can flow out through the first guide channel 31 .

[0135] Furthermore, the heating component 20 can separate the first chamber 201 from the second chamber 202. In addition, the top of the heating component 20 abuts against the bottom of the deflector 30, so that the generation of the first aerosol and the deflection channel 30a are independent of the generation of the second aerosol and the deflection channel 30a, especially when the first aerosol and the second aerosol are made of different materials, so as to avoid the reaction after fusion at high temperature and affect the taste.

[0136] The embodiment of the present application designs the heating component 20 to increase the heated area, thereby increasing the smoke. While increasing the smoke, if the smoke is not cooled down, it will cause the problem of burning the mouth. Based on this, the present application also designs a deflector 30. On the one hand, the deflector 30 allows the smoke to flow smoothly, which can expand and cool down, and realize heat exchange and cooling with the cooling chamber 103, thereby effectively avoiding the problem of smoke burning the mouth.

The mesh plate 60 is provided with a plurality of holes. The mesh plate 60 is installed between the heating chamber 101 and the flow guiding chamber 102 to prevent the atomizing medium 300 in the heating chamber 101 from entering the flow guiding chamber 102, thereby preventing the flow guiding channel 30a of the flow guiding device 30 from being blocked. In addition, the mesh plate 60 can also allow the aerosol to pass through, so as to improve the flow smoothness of the aerosol.
