[0049] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides an electronic atomizer. The electronic atomizer may include an atomizing device 100, a flow guiding device 200, a housing 300, a nozzle 400, a mainboard 500 and a battery 600.

[0050] The atomizing device 100 is connected to the flow guiding device 200 and is accommodated in the housing 300. The suction nozzle 400 is arranged at one end of the housing and is connected to the end of the atomizing device 100 away from the backflow device 200. The mainboard 500 is accommodated in the housing 300 and is electrically connected to the atomizing device 100 and the battery 600 respectively. The mainboard 500 is used to supply the electric energy of the battery 600 to the atomizing device 100 on the one hand, and to control the operation of the atomizing device 100 on the other hand.

[0051] Combine the following Figure 3 The atomization device 100 provided in the embodiment of the present application is described.

[0052] It should be noted that the first direction hereinafter refers to the z direction shown in the figure, the second direction hereinafter refers to the y direction shown in the figure, and the third direction hereinafter refers to the x direction shown in the figure.

[0053] The atomization device 100 provided in the present application includes a liquid storage component 10 , an atomization component 20 and a cooling component 30 .

[0054] The liquid storage component 10 has a liquid storage chamber 111, and the liquid storage chamber 111 is used to store the aerosol generating substrate.

[0055] like Figure 3 As shown, the liquid storage component 10 is a hollow structure, and a liquid storage cavity 111 is formed inside the liquid storage component 10. The liquid storage cavity 111 is suitable for storing a liquid aerosol generating matrix.

[0056] The atomizing assembly 20 penetrates the liquid storage chamber 111 and has an atomizing channel 23 that is in communication with the liquid storage chamber 111. The atomizing assembly 20 is used to heat the aerosol-generating substrate introduced into the atomizing channel 23 to generate aerosol in the atomizing channel 23.

[0057] like Figure 3 As shown, the atomization channel 23 penetrates the liquid storage chamber 111 along the first direction z, and the aerosol generating matrix in the liquid storage chamber 111 can be introduced into the atomization channel 23, so that the atomization component 20 heats the aerosol generating matrix in the atomization channel 23. The aerosol generating matrix can generate a plurality of fine particles uniformly suspended in the air under the heating of the atomization component 20 to form an aerosol, and the aerosol can be diffused into the atomization channel 23 and flow out of the liquid storage chamber 111 along the atomization channel 23.

[0058] The cooling assembly 30 is accommodated in the liquid storage chamber 111 . The cooling assembly 30 is connected to the atomizing assembly 20 . The cooling assembly 30 is used to reduce the temperature of the atomizing assembly 20 .

[0059] The cooling component 30 may be made of one or more materials with good thermal conductivity such as metal, alloy, ceramic, etc. Figure 3 As shown, the cooling component 30 is arranged in the liquid storage chamber 111 so that the cooling component 30 can be immersed in the aerosol generating matrix stored in the liquid storage chamber 111. The cooling component 30 is connected to the atomization component 20 to conduct the heat in the atomization component 20 to the cooling component 30, and dissipate the heat in the atomization component 20 to the liquid storage chamber 111 through the cooling component 30, thereby reducing the temperature of the atomization component 20.

[0060] The beneficial effect of the atomization device 100 provided in the present application is that, compared with the prior art, the atomization device 100 provided in the present application can conduct and dissipate the heat in the atomization component 20 to the liquid storage chamber 111 through the cooling component 30, so as to reduce the temperature of the atomization component 20 through the cooling component 30, thereby reducing the temperature of the aerosol discharged from the low atomization channel 23, thereby improving the user experience.

[0061] like Figure 3 and Figure 5 As shown, in some embodiments provided in the present application, the liquid storage assembly 10 includes a cup body 11 , a first sealing member 12 and a second sealing member 13 .

[0062] The first sealing member 12 is connected to one end of the cup body 11, and an air outlet 121 is provided on the first sealing member 12. The second sealing member 13 is connected to one end of the cup body 11 away from the first sealing member 12, and an air inlet 131 is provided on the second sealing member 13. One end of the air guide tube 22 away from the atomizing core 21 is arranged corresponding to the air outlet 121, and one end of the atomizing core 21 away from the air outlet 121 is inserted into the air inlet 131. Such arrangement can simplify the structure of the liquid storage component 10 and reduce the manufacturing cost of the liquid storage component 10 on the one hand, and can facilitate the aerosol generation matrix and the atomizing component 20 to be accommodated in the liquid storage component 10 on the other hand.

[0063] like Figure 3 As shown, the cup body 11 is a cylindrical structure, and openings are provided at both ends of the cup body 11 along the first direction z. The first sealing member 12 is sealed in the opening at one end of the cup body 11 in the first direction z, and the second sealing member 13 is sealed in the opening at the other end of the cup body 11 in the first direction z, so as to seal the liquid storage chamber 111 through the sealing member.

[0064] Therefore, when part of the aerosol generating substrate in the liquid storage chamber 111 penetrates into the atomizing assembly 20 , a negative pressure area is formed at the top of the liquid storage chamber 111 to prevent excessive leakage of the aerosol generating substrate in the liquid guiding member 212 .

[0065] like Figure 3 As shown, the first seal 12 is located on the upper side of the cup body 11, the second seal 13 is located on the lower side of the cup body 11, the air outlet 121 penetrates the first seal 12 along the first direction z, and the air inlet 131 penetrates the second seal 13 along the first direction z. The air outlet 121 and the air inlet 131 are coaxially arranged, one end of the atomization channel 23 is connected to the air inlet 131, and the end of the atomization channel 23 away from the air inlet 131 is connected to the air inlet 121, so that the aerosol generated in the atomization channel 23 flows from the air inlet 131 to the air outlet 121. When the atomization device 100 provided in the present application is working, air enters the atomization channel 23 from the air inlet 131, pushing the aerosol in the atomization channel 23 to be discharged toward the air outlet 121.

[0066] like Figure 7 As shown, in some embodiments provided in the present application, the inner wall of the air outlet 121 protrudes to form a plurality of diverter sheets 122, and the plurality of diverter sheets 122 are arranged at intervals and evenly surround the inner wall of the air outlet 1211, and a diverter channel 1220 is formed between two adjacent diverter sheets 122; wherein, the transverse cross-sectional area of ​​the diverter sheet 122 gradually increases along the airflow direction of the aerosol, so that the transverse cross-sectional area of ​​the diverter channel 1220 gradually decreases along the airflow direction of the aerosol.

[0067] like Figure 6 and Figure 7As shown, one end of the diverter sheet 122 is connected to the inner wall of the air outlet 121, and the other end of the diverter sheet 122 extends along the radial direction of the air outlet 121 toward the axial direction of the air outlet 121. A plurality of diverter sheets 122 are arranged along the circumference of the air outlet 121, and the transverse cross-sectional area of ​​the diverter sheet 122 is Figure 6 As shown in the cross-sectional area of ​​the xOy plane, the cross-sectional area of ​​the diverter sheet 122 gradually increases along the airflow direction, so that when the aerosol flows through the diverter channel 1220 between two adjacent diverter sheets 122, the flow area of ​​the airflow gradually decreases.

[0068] As a result, the flow area of ​​the aerosol gradually decreases when flowing through the air outlet 121, and the flow area suddenly increases when the aerosol flows from the air outlet 121 to the outside of the liquid storage component 10, so that the aerosol flowing through the air outlet 121 is stirred by the diverter plate 122, which makes the distribution of aerosol particles in the aerosol more uniform on the one hand, and makes the temperature distribution in the aerosol more uniform on the other hand, thereby improving the user experience.

[0069] like Figure 3 and Figure 4 As shown, in some embodiments provided in the present application, the atomizer assembly 20 includes an atomizer core 21. The atomizer core 21 is a hollow cylindrical structure, and the atomizer core 21 extends along the first direction z. The outer wall of the atomizer core 21 is connected to the liquid storage chamber 111, so that the aerosol generating substrate in the liquid storage chamber 111 can be introduced into the atomizer core 21, and heated and atomized on the inner wall of the atomizer core 21 to generate aerosol, and at least a part of the atomization channel 23 is formed on the inner side of the atomizer core 21.

[0070] In some embodiments, the atomization assembly 20 may further include an air guide tube 22. The air guide tube 22 is in communication with the atomization core 21. The atomization channel 23 may be formed by the atomization core 21 and the air guide tube 22.

[0071] like Figure 4 As shown, the air guide tube 22 extends along the first direction z, and one end of the air guide tube 22 is connected to the end of the liquid storage component 10 along the first direction z (specifically, it is arranged in the air outlet hole 121), and the other end of the air guide tube 22 is connected to the atomization core 21. A part of the atomization channel 23 is formed by surrounding the atomization core 21, and another part of the atomization channel 23 is formed by surrounding the air guide tube 22. The air guide tube 22 is a cylindrical structure, and the aerosol generated at the atomization core 21 is conducted to the outside of the liquid storage component 10 through the air guide tube 22.

[0072] In some embodiments provided in the present application, the atomizer core 21 includes a fixing tube 211 , a liquid guiding member 212 and a heating member 213 .

[0073] The fixed cylinder 211 is sleeved and connected with one end of the gas cylinder 22. In this embodiment, one end of the gas cylinder 22 is inserted into the fixed cylinder 211, so that the gas cylinder 22 is connected to the fixed cylinder 211. In other embodiments, one end of the gas cylinder 22 is sleeved in the fixed cylinder 211, so that the gas cylinder 22 is connected to the fixed cylinder 211.

[0074] The fixed cylinder 211 is provided with a liquid inlet 2111, which connects the liquid storage chamber 111 with the atomization channel 23. The liquid guide 212 is attached to the inner wall of the fixed cylinder 211 and is at least partially arranged corresponding to the liquid inlet 2111; the heating element 213 is attached to the liquid guide 212, and is used to heat the aerosol generating matrix on the liquid guide 212 to generate aerosol in the atomization airway 23. The cooling component 30 is connected to the fixed cylinder 211, and is used to reduce the temperature of the fixed cylinder 211, thereby reducing the temperature of the heating element 213, and preventing the heating element 213 from partially overheating and carbonizing the liquid guide 212.

[0075] The liquid guide 212 may be an oil storage cotton and has a fiber mesh porous structure so that the aerosol generating matrix can penetrate into the liquid guide 212 under capillary action. Figure 4 As shown, the liquid guiding member 212 is a tubular structure, and the fixed tube 211 is sleeved on the outer peripheral side of the liquid guiding member 212, one end of the fixed tube 211 is against the inner wall of the liquid storage chamber 111, and the other end of the fixed end is sleeved and connected with the air guiding tube 22 to fix the liquid guiding member 212 in the liquid storage chamber 111.

[0076] The fixed cylinder 211 is provided with a liquid inlet 2111 , so that the aerosol generating substrate in the liquid storage chamber 111 can pass through the liquid inlet 2111 and contact the outer wall of the liquid guide 212 , thereby allowing the aerosol generating substrate in the liquid storage chamber 111 to enter the liquid guide 212 .

[0077] In some embodiments, Figure 4 As shown, part of the liquid guiding member 212 may extend through the liquid inlet 2111 to the outside of the fixed cylinder 211 to increase the contact area between the liquid guiding member 212 and the aerosol generating substrate in the liquid storage chamber 111 .

[0078] In some embodiments, there are multiple liquid inlets 2111 , and the multiple liquid inlets 2111 are arranged along the circumference of the fixed cylinder 211 to increase the contact area between the liquid guide 212 and the aerosol generating substrate in the liquid storage chamber 111 .

[0079] The heating element 213 can generate heat when powered on. The heating element 213 is a cylindrical structure. The outer wall of the heating element 213 abuts against the inner wall of the liquid guiding element 212. The inner wall of the heating element 213 forms a part of the atomization channel 23. The heating element 213 and the liquid guiding element 212 extend coaxially. The liquid guiding element 212 can guide the aerosol generating matrix on its outer wall to the inner wall of the liquid guiding element 212. The heating element 213 can contact the aerosol generating matrix on the inner wall of the liquid guiding element 212 to heat the aerosol generating matrix through the heating element 213 and generate an aerosol.

[0080] The cooling assembly 30 is connected to the atomizer core 21 and is used to reduce the temperature of the atomizer core 21. The cooling assembly 30 is located on at least a portion of the outer wall of the atomizer core 21 to conduct heat in the atomizer assembly 20 through the cooling assembly 30, thereby reducing the temperature of the atomizer core 21, and further reducing the temperature of the aerosol generated from the atomizer core 21.

[0081] Specifically, the cooling component 30 is connected to the outer wall of the fixed cylinder 211. When the heating element 213 is working, the heat generated by the heating element 213 is conducted to the fixed cylinder 211 through the liquid guiding element 212, so that the temperature of the fixed cylinder 211 increases. The temperature of the fixed cylinder 211 is reduced by the cooling component 30, which can indirectly reduce the temperature of the inner wall of the liquid guiding element 212, thereby indirectly reducing the temperature of the aerosol in the inner wall of the liquid guiding element 212, so that the temperature of the liquid guiding element 212 is maintained within a reasonable temperature range, preventing the heating element 213 from bursting out too much power and carbonizing the liquid guiding element 212. At the same time, it can reduce the temperature of the aerosol discharged from the low atomization channel 23, thereby improving the user experience.

[0082] In some embodiments provided in the present application, the cooling assembly 30 includes a connecting member 31 and a heat sink 32 .

[0083] like Figure 3 and Figure 8 As shown, the connecting member 31 is connected to the fixing tube 211 , one end of the heat sink 32 is connected to the connecting member 31 , and one end of the heat sink 32 away from the connecting member 31 extends into the liquid storage chamber 111 .

[0084] In some embodiments, the connection member 31 and the heat sink 32 are an integrated structure to increase the heat conduction efficiency between the connection member 31 and the heat sink 32 .

[0085] The connecting member 31 is connected between the heat sink 32 and the fixed cylinder 211, so that the heat on the surface of the fixed cylinder 211 is transferred to the heat sink 32 through the connecting member 31. The heat sink 32 can extend into the liquid storage chamber 111 and fully contact the aerosol generating substrate in the liquid storage chamber 111, so that the heat in the connecting member 31 is dissipated to the aerosol generating substrate in the liquid storage chamber 111 through the heat sink 32, thereby reducing the temperature of the fixed cylinder 211 through the cooling component 30.

[0086] In some embodiments provided in the present application, the connecting member 31 is a hollow cylindrical structure, and a relief opening 3111 corresponding to the liquid inlet 2111 is provided on the connecting member 31, and the connecting member 31 is sleeved on the fixed cylinder 211. The heat sink 32 is formed by extending from one end edge of the connecting member 31, and the heat sink 32 abuts against the bottom of the liquid storage chamber 111.

[0087] like Figure 3 and Figure 8 As shown, the connector 31 is a tubular structure extending along the first direction z, and the connector 31 is provided with an escape opening 3111, and the escape opening 3111 passes through the outer wall of the connector 31 and the inner wall of the connector 31, and the connector 31 is sleeved on the outer side of the fixed tube 211 so that the inner wall of the connector 31 contacts part of the outer wall of the fixed tube 211 for heat conduction.

[0088] Heat sink 32 Figure 8 The end of the heat sink 32 along the second direction y abuts against the inner wall of the liquid storage chamber 111 along the second direction y, and the end of the heat sink 32 along the third direction x abuts against the inner wall of the liquid storage chamber 111 along the third direction x. The heat sink 32 is connected to the bottom end of the connecting member 31 in the first direction z, so that the heat sink 32 can contact the aerosol generating matrix gathered at the bottom end of the liquid storage chamber 111 (i.e., the second sealing member 13). In other embodiments, the heat sink 32 can be attached not only to the second sealing member 13, but also to the inner wall of the cup body 11, so as to further increase the heat dissipation area of ​​the heat sink 32 and improve the heat dissipation performance of the heat sink 32.

[0089] Thus, the heat sink 32 conducts heat to the aerosol generating matrix in the liquid storage chamber 111. The aerosol generating matrix is ​​a liquid. The aerosol generating matrix with a higher temperature has a lower density and accumulates at the top of the liquid storage chamber 111, while the aerosol generating matrix with a lower temperature has a higher density and accumulates at the bottom of the liquid storage chamber 111, thereby increasing the temperature difference between the heat sink 32 and the aerosol generating matrix in contact with its surface, thereby improving the heat transfer efficiency between the heat sink 32 and the aerosol generating matrix.

[0090] In some other embodiments of the present application (not shown in the figures), the heat sink 32 is located between the two ends of the connecting member 31 in the first direction z, that is, the heat sink 32 divides the liquid storage chamber 111 into two upper and lower parts, so that the flow inertia of the aerosol generating matrix in the liquid storage chamber 111 can be reduced by the heat sink 32 to prevent excessive leakage of the aerosol generating matrix in the liquid guiding member 212.

[0091] In some embodiments provided in the present application (not shown in the drawings), the connecting member 31 and the fixing tube 211 are integrally formed.

[0092] The connecting member 31 and the fixed tube 211 are both made of a material with good thermal conductivity such as metal, alloy, ceramic, etc. The integral molding of the connecting member 31 and the fixed tube 211 reduces the thermal resistance between the connecting member 31 and the fixed tube 211, thereby improving the cooling effect of the cooling component 30 on the aerosol in the atomization channel 23.

[0093] In some embodiments provided in the present application, the heat sink 32 is a heat sink fin or a heat sink honeycomb.

[0094] In some embodiments (not shown in the figures), the heat sink 32 includes a main body and a protrusion, and the protrusion is arranged on the surface of the main body to increase the contact area between the heat sink 32 and the aerosol generating matrix in the liquid storage chamber 111 through the protrusion, thereby enhancing the cooling effect of the cooling component 30 on the aerosol in the atomization channel 23.

[0095] In other embodiments, Figure 8 As shown, a plurality of through holes 321 are provided in the heat sink 32, and the plurality of through holes 321 penetrate the heat sink 32 along the first direction z, thereby increasing the contact area between the heat sink 32 and the aerosol generating matrix in the liquid storage chamber 111 through the plurality of through holes 321, thereby enhancing the cooling effect of the cooling component 30 on the aerosol in the atomization channel 23.

[0096] In some embodiments provided in the present application, the atomization device 100 may further include a flow equalizer 40 , which is disposed on the inner wall of the air inlet 131 and corresponds to the heating element 213 .

[0097] The flow balancing member 40 is provided with a plurality of flow balancing holes 41 , which penetrate the flow balancing member 40 along the airflow direction in the atomizing channel 23 , and are arranged in a direction orthogonal to the airflow direction in the atomizing channel.

[0098] like Figure 3 As shown, the flow equalizing member 40 is disposed on the side of the air inlet 131 facing the atomizer core 21, so that the air flowing from the air inlet 131 to the atomizer core 21 passes through the multiple flow equalizing holes 41, and the airflow flowing from the air inlet 131 to the atomizer core 21 is disturbed by the multiple flow equalizing holes 41, thereby increasing the turbulence of the airflow entering the atomizer core 21.

[0099] Therefore, the turbulence of the airflow entering the atomizer core 21 is increased by the flow equalizer 40. On the one hand, the aerosol particles generated by the atomizer core 21 can be evenly distributed in the aerosol through the airflow disturbance. On the other hand, the temperature distribution in the aerosol can be evenly distributed through the airflow disturbance, thereby improving the user experience. On the third hand, the cooling effect on the heating element 213 can be improved through the airflow disturbance, thereby avoiding the accumulation of heat in the heating element 213.

[0100] The working principle of the atomization device 100 provided in the embodiment of the present application is as follows:

[0101] When the atomization device 100 provided in the embodiment of the present application is working, the aerosol generating matrix in the liquid storage chamber 111 can contact the outer wall of the liquid guiding member 212 through the avoidance port 3111 and the liquid inlet 2111, and the liquid guiding member 212 can allow the aerosol generating matrix in contact with its outer wall to penetrate into the inner wall of the liquid guiding member 212 and contact the heating member 213 to generate aerosol, and the heat generated by the heating member 213 can be transferred to the connecting member 31 in the cooling component 30 through the liquid guiding member 212, and the heat dissipation member 32 dissipates the heat in the connecting member 31 to the aerosol generating matrix stored in the liquid storage chamber 111, so as to cool the aerosol in the liquid guiding member 212 and the atomization channel 23 around the heating member 213.

[0102] In addition, when the user inhales the gas in the atomization channel 23 at the air outlet 121 of the atomization device 100 , the air outside the atomization device 100 enters the atomization channel 23 from the air inlet 131 and forms an aerosol, and the aerosol in the atomization channel 23 is discharged from the air outlet 121 of the atomization device 100 .

[0103] In the process of air outside the atomization device 100 entering the atomization channel 23 to form an aerosol, the air flow entering the atomization channel 23 first passes through the flow equalizer 40 before contacting the heating element 213. The flow equalizer 40 increases the turbulence of the air around the heating element 213, so that the aerosol particles are evenly distributed in the air flow passing through the heating element to form an aerosol, and the temperature of the aerosol is reduced.

[0104] During the process of the aerosol in the atomization channel 23 being discharged from the air outlet 121 of the atomization device 100, when the aerosol passes through the diverter channel 1220 between the diverter pieces 122 of the air outlet 121, the turbulence of the aerosol increases. On the one hand, the heat in the aerosol is evenly distributed to prevent the aerosol from becoming hot after entering the user's mouth. On the other hand, the aerosol particles in the aerosol are evenly distributed to enhance the user experience.

[0105] Combine the following Figure 1 and Figure 2 The electronic atomizer provided in this application is described.

[0106] The electronic atomizer provided in the present application includes an atomization device 100 and a nozzle 400 .

[0107] The electronic atomizer provided in the present application may be an atomization device such as an electronic cigarette, a medical atomizer, etc.

[0108] The atomization device 100 provided in the present application has the advantages of better cooling effect on the aerosol in its atomization channel 23 and better user experience. The atomization device 100 in the electronic atomizer provided in the present application is the atomization device 100 in any of the above-mentioned embodiments. Therefore, the atomization device 100 can improve the user experience of the electronic atomizer provided in the present application.

[0109] like Figure 1 and Figure 2 As shown, the nozzle 400 is connected to the atomization channel 23, and an air outlet channel 401 is provided on the nozzle 400; wherein the cross-sectional area of ​​the air outlet channel 401 gradually increases along the airflow direction of the aerosol.

[0110] like Figure 1 and Figure 2 As shown, the nozzle 400 is arranged at the end of the shell 300 close to the air outlet 121, and the nozzle 400 is sealed against the liquid storage component 10 to connect the atomization channel 23 with the air outlet channel 401. When the user uses the electronic atomizer provided by the present application, the aerosol in the atomization channel 23 is sucked through the nozzle 400, so that the aerosol enters the user's mouth through the air outlet channel 401.

[0111] The throttling area of ​​the aerosol gradually increases when flowing through the air outlet channel 401, thereby increasing the turbulence of the aerosol fluid. On the one hand, the aerosol fluid disturbance can make the aerosol particles evenly distributed in the aerosol. On the other hand, the aerosol fluid disturbance can make the temperature in the aerosol evenly distributed, thereby preventing the aerosol from becoming hot when being sucked into the user's mouth and improving the user experience.

[0112] In some embodiments provided in the present application, the electronic atomizer also includes a shell 300 and a guide device 200, the shell 300 has a accommodating cavity, the atomizing device 100 and the guide device 200 are both accommodated in the accommodating cavity, an air inlet hole 302 is provided at one end of the shell 300, the guide device 200 is sealed and connected to the liquid storage component 10 of the atomizing device 100 and a guide cavity 201 is formed between the guide device 200 and the liquid storage component 10, the air inlet 131 is connected to the guide cavity 201, the guide device 200 includes a guide tube 202, one end of the guide tube 202 is sealed and connected to the guide cavity 201, and the other end of the guide tube 202 extends to the air inlet hole 302 and is connected to the air inlet hole 302.

[0113] like Figure 1 and Figure 5As shown, the outer shell 300 includes a first shell 303 and a second shell 304. The first shell 303 and the second shell 304 are spliced ​​along the second direction y to form the outer shell 300, so that seams 305 are formed at both ends of the inner cavity 301 along the third direction x. Air can flow between the inner cavity 301 and the outside of the outer shell 300 through the seams 305. The first shell 303 has an air inlet 302 at one end away from the air outlet 121 along the first direction z, so that air outside the outer shell 300 can enter the inner cavity 301 through the air inlet 302.

[0114] like Figure 2 As shown, the guide device 200 is made of elastic material such as rubber, and is located on the side of the liquid storage component 10 away from the air outlet 121 along the first direction z. The end of the guide device 200 close to the liquid storage component 10 is sealed and connected to the end of the liquid storage component 10 close to the guide device 200, so that the air inlet 131 is connected to the guide cavity 201, and the guide cavity 201 is sealed and connected to one end of the guide tube 202, and the other end of the guide tube 202 is arranged corresponding to the air inlet 302 along the first direction z.

[0115] Therefore, by setting the guide device 200, the air can only flow along Figure 2 The path of "air inlet hole 302-guide tube 202-guide cavity 201-air inlet 131" shown in the figure enters the atomization channel 23, avoiding the air flow direction entering the air inlet 131 being too chaotic and affecting the air intake efficiency of the air inlet 131, thereby improving the air flow velocity in the atomization channel 23 and reducing the temperature of the aerosol.

[0116] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
