The ends of the fourth capillary groove 1432 are directly connected to the end of the third capillary groove 1431. The bottom of the fourth capillary groove 1432 is flush with the surface of the second guide plate 1422 or the third guide plate 1423 exposed through the window 117. In an optional embodiment, there may be multiple fourth capillary grooves 1432 arranged parallel to each other, and the ends of the multiple fourth capillary grooves 1432 away from the window 117 are connected to each other. The ends of the multiple fourth capillary grooves 1432 near the window 117 may all be connected to the second guide plate 1422 and the third guide plate 1423, and the ends of the multiple fourth capillary grooves 1432 near the window 117 may partially be connected to the second guide plate 1422 and / or the third guide plate 1423.

[0078] The fourth capillary groove 1432 can collect condensate overflowing from the first liquid collecting portion 141 through capillary action. Specifically, when the condensate in the third capillary groove 1431 overflows onto the exposed surface of the second guide plate 1422 and / or the third guide plate 1423, the condensate overflowing on the second guide plate 1422 and / or the third guide plate 1423 is collected and does not break through the surface tension of the condensate or reach the condensate's own gravity, that is, the condensate does not separate from the third guide plate 1423 or the second guide plate 1422. The end of the fourth capillary groove 1432 connected to the second guide plate 1422 or the third guide plate 1423 absorbs the condensate through capillary action, absorbing the condensate on the second guide plate 1422 or the third guide plate 1423 into the fourth capillary groove 1432. When the electronic atomization device 100 is placed horizontally, the condensed liquid will flow into the cavity formed by the window 117 and the atomizer housing 209 due to gravity. Since the end of the fourth capillary groove 1432 is exposed through the window 117, that is, the fourth capillary groove 1432 is connected to the window 117, the end of the fourth capillary groove 1432 will absorb the condensed liquid in the cavity formed by the window 117 and the atomizer housing 209 through capillary force and collect it in the fourth capillary groove 1432. In an optional embodiment, please refer to Figure 9 A liquid collection hole 1435 may also be provided on the outer wall of the mounting base 1. The liquid collection hole 1435 is provided at the end of the fourth capillary groove 1432 away from the window 117. The liquid collection hole 1435 can be connected with the end of all the fourth capillary grooves 1432 away from the window 117, and can also be connected with the end of some of the fourth capillary grooves 1432 away from the window 117.

[0079] An air guide groove structure 151 is provided on the upper body 11. In an optional embodiment, the air guide groove structure 151 is provided on the outer wall of the upper body 11. The air guide groove structure 151 is provided in a direction extending from the end near the lower body 12 to the end near the upper body 11 where the air outlet 128 is provided. The air guide groove structure 151 is directly connected to the air guide hole structure 152 on the end surface of the upper body 11 where the air outlet 128 is provided. The air inlet 126 connects the air guide groove structure 151 and the liquid storage tank 4. The atomizer housing 209 covers the opening 31 of the air guide groove structure 151, thereby forming a ventilation channel 15. The ventilation channel 15 is used to transmit the external atmosphere to the liquid storage tank 4 to balance the air pressure in the liquid storage tank 4 and the atomization chamber 125. One end of the ventilation channel 15 is connected to the liquid storage tank 4 through the air guide hole structure 152, and the other end of the ventilation channel 15 is set at the end of the upper body 11 close to the lower body 12, and the ventilation channel 15 is connected to the atomizing chamber 125 through the gap between the upper body 11 and the lower body 12. In a preferred embodiment, please refer to Figure 10 , Figure 10This is a schematic diagram of the structure of the first embodiment of the lower body of the electronic atomizer device provided by the present invention. A ventilation communication groove 159 is provided on the lower body 12. The ventilation communication groove 159 is used to connect the ventilation channel 15 and the atomizing chamber 125. The ventilation communication groove 159 is located at the corresponding position of the ventilation channel 15 and the lower body 12.

[0080] The upper body 11 is also provided with a fifth capillary groove 1433. The condensate collection structure 14 includes the fifth capillary groove 1433, which is disposed on the outer wall of the upper mounting body 11. The fifth capillary groove 1433 is disposed on both sides of the ventilation channel 15 and is connected to the ventilation channel 15. The fifth capillary groove 1433 is used to collect liquid that leaks into the ventilation channel 15 through the air guide hole structure 152. There may be multiple fifth capillary grooves 1433, and the arrangement direction of the multiple fifth capillary grooves 1433 can be the same as the arrangement direction of the fourth capillary groove 1432, that is, the arrangement direction of the fifth capillary groove 1433 is perpendicular to the arrangement direction of the ventilation channel 15. In another alternative embodiment, the end of the fifth capillary groove 1433 away from the ventilation channel 15 is connected to the end of the fourth capillary groove 1432 away from the window 117. In another alternative embodiment, the end of the fifth capillary groove 1433 away from the ventilation channel 15 is connected to the liquid collection hole 1435.

[0081] In an alternative embodiment, see Figure 5 The condensate collecting structure 14 includes a sixth capillary groove 1434 , which is arranged on the inner wall of the gas outlet channel 131 . The sixth capillary groove 1434 is used to absorb the condensate in the gas outlet channel 131 to prevent the condensate in the gas outlet channel 131 from dripping into the atomization chamber 125 .

[0082] When the pressure in the liquid reservoir 4 increases, the liquid squeezed out of the liquid reservoir 4 overflows into the ventilation channel 15, and the fifth capillary groove 1433 locks the liquid in the ventilation channel 15 through capillary force. When the pressure in the liquid reservoir 4 decreases, the pressure in the fifth capillary groove 1433 exceeds the pressure in the liquid reservoir 4, and the liquid in the fifth capillary groove 1433 flows back into the liquid reservoir 4 through the ventilation channel 15.

[0083] In another alternative embodiment, see Figure 8An air guide groove structure 151 is provided on the outer wall of the upper body 11. The air guide groove structure 151 is provided on the outer wall of the upper body 11 near the air outlet end. A recessed portion is provided on the outer wall of the upper body 11 near the lower body 12. The recessed portion is connected to the air guide groove structure 151. The atomizer housing 209 covers the recessed portion and the air guide groove structure 151, thereby forming a ventilation channel 15. The ventilation channel 15 is further used as a liquid collection bin for collecting the condensate collection structure 14 and / or the liquid missed in the ventilation channel 15. One end of the air guide groove structure 151 is connected to the liquid storage tank 4 through the air guide hole structure 152, and the other end is connected to the recessed portion. The air inlet of the ventilation channel 15 is provided on the side wall of the upper body 11, that is, the air inlet of the ventilation channel 15 is provided on the bottom wall 301 of the recessed portion, connecting the atomization chamber 125 and the recessed portion. The air outlet of the ventilation channel 15 is connected to the liquid storage tank 4 through the air guide hole structure 152. The position of the air inlet is higher than the bottom of the liquid collection tank, so that the air inlet to the bottom of the liquid collection tank can collect the leaked liquid in the ventilation channel 15.

[0084] A first sealing member 316 is provided at one end of the ventilation channel 15 close to the liquid storage tank 4. Figure 11 , Figure 11 It is a structural schematic diagram of the first sealing component in the electronic atomization device provided by the present invention. An air outlet hole 162 and a lower liquid hole 163 are provided on the first sealing component 316. The liquid in the liquid storage tank 4 enters the lower liquid chamber 116 through the lower liquid hole 163, and the air outlet hole 162 is used to pass through the air outlet pipe 132. A one-way valve 161 that matches the port of the ventilation channel 15 is provided on the first sealing component 316. The one-way valve 161 is used to prevent the liquid in the liquid storage tank 4 from leaking into the ventilation channel 15; when the air pressure in the liquid storage tank 4 is lower than the external atmospheric pressure, the gas in the ventilation channel 15 will push open the one-way valve 161, causing the one-way valve 161 to open in the direction close to the liquid storage tank 4, so that the gas enters the liquid storage tank 4, and then the leaked liquid flows back to the liquid storage tank 4 through the ventilation channel 15.

[0085] The mounting base 1 includes a shell 113 and a partition 114 arranged in the shell 113 . The partition 114 has a lower liquid hole 111 . The lower liquid hole 111 is communicated with the liquid storage tank 4 , that is, the lower liquid hole 111 is connected to the liquid storage tank 4 .

[0086] In this embodiment, a partition 114 divides the space within the housing 113 into a lower liquid chamber 116 and an access chamber 115. The lower liquid chamber 116 and the access chamber 115 are connected via the partition 114. An air outlet passage 131 is also provided on the housing 113 on the same side as the lower liquid chamber 116. The mounting base 1 is embedded in the atomizer housing 209, and the vent pipe is connected to the air outlet passage 131. The smoke from the atomizing chamber 125 is directed through the air flow passage 13 and the vent pipe to the user's mouth.

[0087] In other embodiments, the mounting base 1 may not be embedded in the atomizer housing 209, but only requires the lower liquid hole 111 to be connected to the liquid storage tank 4. For example, the liquid storage tank 4 is a flexible liquid storage tank, a liquid storage ball, etc., which is connected to the partition 114 and the liquid storage tank 4 is connected to the lower liquid hole 111.

[0088] The partition 114 can be a plate body with a lower liquid hole 111 in the middle, or the partition 114 can be a plate with multiple lower liquid holes 111 in the middle. It only needs to be connected to the liquid storage tank 4 through the lower liquid hole 111 on the partition 114. This application does not impose any restrictions on this.

[0089] The atomizer core 2 is assembled in the access cavity 115 and blocks the lower liquid cavity 116 . The atomizer core 2 is in communication with the lower liquid cavity 116 . The lower liquid cavity 116 and the lower liquid hole 111 guide the tobacco oil to the atomizer core 2 so that the atomizer core 2 atomizes the tobacco oil to form smoke.

[0090] The seal 3 is located on the side of the partition 114 facing away from the liquid reservoir 4 and between the partition 114 and the atomizer core 2. The atomizer core 2 presses against the seal 3 to prevent liquid leakage. The seal 3 has an opening 31 that communicates with the lower liquid hole 111. Thus, the opening 31 connects to the liquid reservoir 4, and the liquid enters the atomizer core 2 through the opening 31.

[0091] The lower body 12 is connected to and covers the end of the upper body 11 facing away from the liquid storage tank 4. The lower body 12 abuts the atomizer core 2, so that the atomizer core 2 abuts the seal 3. The space formed by the upper body 11, the atomizer core 2 and the lower body 12 forms an atomizing chamber 125. The atomizer core 2 atomizes the e-liquid to form smoke in the atomizing chamber 125, and the atomizing chamber 125 is communicated with the air flow channel 13.

[0092] In another optional embodiment, an air guide groove structure 151 is provided between the mounting base 1 and the sealing member 3. The air guide groove structure 151 connects the liquid storage tank 4 with the external atmosphere. After the liquid storage space is filled with e-liquid, the e-liquid seals the air guide groove structure 151.

[0093] The air guide groove structure 151 can connect the atomizing chamber 125 and the liquid storage tank 4 , and further connect the liquid storage tank 4 and the external atmosphere through the atomizing chamber 125 .

[0094] In the present application, an air guide groove structure 151 is provided between the mounting base 1 and the sealing member 3, and the air guide groove structure 151 connects the liquid storage tank 4 and the atomization chamber 125, so that the air pressure and hydraulic pressure in the liquid storage tank 4 and the capillary tension, resistance and atmospheric pressure of the air guide groove structure 151 on the e-liquid are dynamically balanced by adjusting the e-liquid stored in the air guide groove structure 151, thereby avoiding the occurrence of liquid discharge and leakage in the atomizer 10, and improving the quality of the atomizer 10.

[0095] Specifically, when the pressure in the liquid reservoir 4 drops to a negative pressure threshold, air in the atomizing chamber 125 can enter the liquid reservoir 4 through the air guide groove structure 151 for ventilation, thereby increasing the pressure in the liquid reservoir 4. This prevents the poor liquid flow caused by low pressure in the chamber, thereby improving the quality of the atomizer 10. When the pressure in the liquid reservoir 4 increases due to heating, more e-liquid enters the air guide groove structure 151, thereby appropriately reducing the pressure in the liquid reservoir 4, preventing leakage, and similarly improving the quality of the atomizer 10.

[0096] In other embodiments, the seal 3 is provided with an air guide groove structure 151. Specifically, the air guide groove structure 151 is provided on the side of the seal 3 facing the partition 114 and / or the side of the seal 3 facing the atomizer core 2, or the air guide groove structure 151 can also be provided inside the seal 3.

[0097] For example, see Figure 12 , Figure 12 This is a schematic diagram of the structure of an embodiment of a seal in an electronic atomization device provided by the present invention. Six air guide grooves 151 are provided on the side of the seal 3 facing the partition 114 and / or the side of the seal 3 facing the atomizer core 2, allowing for extremely convenient adjustment of the air pressure within the liquid storage tank 4.

[0098] In one embodiment, if Figure 13 As shown, Figure 13 This is a schematic diagram of the structure of the first embodiment of the ventilation channel in the electronic atomization device provided by the present invention. The air guide groove structure 151 is provided on the side of the partition 114 facing away from the liquid storage tank 4. The air guide groove structure 151 is covered by the seal 3, leaving only the air guide hole communicating with the lower liquid hole 111 and the air inlet hole 126 communicating with the atomization chamber 125 exposed.

[0099] Since the air guide groove structures 151 are all located on the side of the partition 114 away from the liquid storage tank 4, the liquid in the air guide groove structures 151 has a relatively same hydraulic pressure value.

[0100] The air guide groove structure 151 can be arranged in a circuitous manner on the partition 114 to increase the flow resistance of the liquid leakage from the air guide groove structure 151 and extend the leakage path of the liquid. The air guide groove structure 151 can also be arranged in a straight line, as long as the air guide groove structure 151 can connect the lower liquid hole 111 and the atmosphere. This application does not impose any restrictions on this.

[0101] The air guide groove structure 151 can also be provided in multiple pieces. The multiple air guide groove structures 151 can simultaneously perform ventilation to increase the air pressure in the liquid storage tank 4. The multiple air guide groove structures 151 can also simultaneously allow liquid to be introduced to reduce the air pressure in the liquid storage tank 4. Therefore, the multiple air guide groove structures 151 can increase the convenience of adjusting the air pressure in the liquid storage tank 4, so that the air pressure in the liquid storage tank 4 can be quickly adjusted. The air guide groove structure 151 can also be provided in one piece. The present application does not impose any restrictions on the number of air guide groove structures 151.

[0102] A cache groove 153 is also provided on the side of the partition 114 facing away from the liquid storage tank 4. The air guide groove structure 151 flows through the cache groove 153. The cross-sectional area of ​​the cache groove 153 along the path direction of the air guide groove structure 151 is larger than the cross-sectional area of ​​the air guide groove structure 151 in the same direction. The seal 3 covers the air guide groove structure 151 and the cache groove 153 to prevent liquid leakage from the air guide groove structure 151 and the cache groove 153.

[0103] The buffer groove 153 is used to buffer the e-liquid, and the cross-sectional area of ​​the buffer groove 153 along the path direction of the air guide groove structure 151 is larger than the cross-sectional area of ​​the air guide groove structure 151 in the same direction, thereby improving the liquid storage capacity of the air guide groove structure 151 to prevent the e-liquid from leaking from the air guide groove structure 151.

[0104] After research, it was found that the depth of the air guide groove structure 151 should be set to 0.1mm to 0.5mm, the width of the air guide groove structure 151 in the direction perpendicular to its path direction should be set to 0.1mm to 0.5mm, and the width of the cache groove 153 is greater than the width of the air guide groove structure 151, and the depth of the cache groove 153 is greater than or equal to the depth of the air guide groove structure 151.

[0105] Specifically, the air inlet 126 of one air guide groove structure 151 is adjacent to the ventilation port of another air guide groove structure 151, and the ventilation port of the air guide groove structure 151 is adjacent to the air inlet 126 of the other air guide groove structure 151, and the two air guide groove structures 151 are arranged around the liquid lowering hole 111, the ventilation port is connected to the liquid storage tank 4, and the air inlet 126 is connected to the atmosphere, so that the air guide groove structure 151 has a longer length, can store more e-liquid, and can also conveniently adjust the air pressure in the liquid storage tank 4, and the ventilation ports of the two air guide groove structures 151 are arranged in different positions, which can avoid the bubbles generated by the ventilation ports in the same place from aggregating and increasing the difficulty of e-liquid lowering.

[0106] The length and cross-sectional area of ​​the air guide groove structure 151 and the length and cross-sectional area of ​​the buffer groove 153 can be set according to the specifications of the atomizer 10 to facilitate adjusting the air pressure in the liquid storage tank 4.

[0107] Specifically, a ventilation channel 15 is provided on the partition 114 of the upper body 11, and the ventilation channel 15 includes an air guide hole structure 152 and an air guide groove structure 151. Among them, the air guide hole structure 152 passes through the partition 114, and the air guide hole structure 152 and the lower liquid hole 111 are spaced apart, and the air guide hole structure 152 connects the lower liquid chamber 116 and the access chamber 115.

In another optional embodiment, the other end of the air guide groove structure 151 can also be directly connected to the outside atmosphere. Among them, the cross-section of the air guide hole structure 152 can be at least one of a circular, elliptical, rectangular, semicircular, etc. shape, or other shapes that are convenient for air conduction. The number of air guide groove structures 151 connected to the air guide hole structure 152 can be one or more, and the number of air guide groove structures 151 can be designed according to actual needs. A silicone sealing ring is provided between the upper body 11 and the atomizer core 2. The silicone sealing ring abuts one end of the air guide hole structure 152 connected to the air guide groove structure 151, and the side wall of the silicone sealing ring abuts the opening 31 of the air guide groove structure 151, so that the air guide hole structure 152 and the air guide groove structure 151 form an air exchange channel 15 between the partition 114 and the silicone sealing ring. The dimensions of the air guide groove structure 151 can be the depth and width of the air guide groove structure 151.

[0116] In another optional embodiment, one end of the first air guide groove 1511 is connected to the atomizing chamber 125 or the outside atmosphere, and the other end is connected to the first air guide hole 1521.

[0117] In one embodiment, see Figure 18 , Figure 18: This is a structural diagram of the sixth embodiment of the ventilation channel in the electronic atomization device provided by the present invention.

[0123] In one embodiment, see Figure 20 , Figure 20This is a schematic diagram of the structure of the eighth embodiment of the ventilation channel in the electronic atomization device provided by the present invention. The ventilation channel 15 includes an air guide hole structure 152 and an air guide groove structure 151 connected to the air guide hole structure 152. The air guide groove structure 151 includes a first air guide groove 1511 and a second air guide groove 1512. The air guide hole structure 152 includes a first air guide hole 1521 and a second air guide hole 1522. The first air guide hole 1521 and the second air guide hole 1522 are both provided on the partition 114 and spaced apart from the lower liquid hole 111. In order to make the air pressure at various locations in the liquid storage tank 4 consistent, the first air guide hole 1521 and the second air guide hole 1522 are symmetrically provided on both sides of the lower liquid hole 111.

One end of the second air guide groove 1512 is connected to the end of the second air guide hole 1522 away from the lower liquid chamber 116, and the other end of the second air guide groove 1512 extends along the partition 114 to a position close to the first air guide hole 1521, extends along the inner wall of the access chamber 115, and is connected to the atomizing chamber 125, and is connected to the outside atmosphere through the air inlet 126 provided at the bottom of the atomizing chamber 125.

[0124] In another optional embodiment, the end of the first air guiding groove 1511 away from the first air guiding hole 1521 and the end of the second air guiding groove 1512 away from the second air guiding hole 1522 pass through the shell 113 and are directly connected to the outside atmosphere.

[0125] In another optional embodiment, one of the ends of the first air guide groove 1511 away from the first air guide hole 1521 and the end of the second air guide groove 1512 away from the second air guide hole 1522 passes through the shell 113 and is directly connected to the outside atmosphere, and the other end is connected to the atomization chamber 125 and is connected to the outside atmosphere through the air inlet hole 126 at the bottom of the atomization chamber 125.

[0126] In another alternative embodiment, see Figure 21 , Figure 21It is a structural diagram of the ninth embodiment of the ventilation channel in the electronic atomization device provided by the present invention. The air guide groove structure 151 also includes a third air guide groove 1513 and a fourth air guide groove 1514. One end of the third air guide groove 1513 is connected to the first air guide hole 1521, and the other end is connected to the lower liquid hole 111; one end of the fourth air guide groove 1514 is connected to the second air guide hole 1522, and the other end is connected to the lower liquid hole 111. The third air guide groove 1513 can transmit the gas transmitted in the first air guide groove 1511 through the lower liquid hole 111, and the fourth air guide groove 1514 can transmit the gas transmitted in the second air guide groove 1512 through the lower liquid hole 111, so that the first air guide hole 1521, the second air guide hole 1522 and the lower liquid hole 111 can transmit gas at the same time, shortening the time to balance the liquid storage tank 4 and the external atmospheric pressure.

[0127] In another optional embodiment, one end of the first air guide groove 1511 is connected to the atomizing chamber 125 or the outside atmosphere, and the other end is connected to the first air guide hole 1521. One end of the third air guide hole structure 152 is directly connected to the atomizing chamber 125 or the outside atmosphere, and the other end is connected to the lower liquid hole 111. One end of the second air guide groove 1512 is connected to the atomizing chamber 125 or the outside atmosphere, and the other end is connected to the second air guide hole 1522. One end of the air guide hole structure 152 is directly connected to the atomizing chamber 125 or the outside atmosphere, and the other end is connected to the lower liquid hole 111.

[0128] The liquid in the liquid storage tank 4 flows to the atomizer core 2 through the lower liquid hole 111. If the pressure in the liquid storage tank 4 decreases, the speed at which the liquid in the liquid storage tank 4 flows to the atomizer core 2 through the lower liquid hole 111 is slower than the speed at which the atomizer core 2 atomizes the liquid. Gas is then transferred to the liquid storage tank 4 through the ventilation channel 15, so that the air pressure in the liquid storage tank 4 is balanced with the air pressure of the outside atmosphere.

[0129] In a specific embodiment, when a user draws on the electronic atomization device 100, the atomizer core 2 atomizes the e-liquid. The air pressure in the atomization chamber 125 is greater than the air pressure in the liquid storage tank 4. The atomization chamber 125 is connected to the outside atmosphere. The air from the outside atmosphere enters the atomization chamber 125 through the air inlet 126. The gas in the atomization chamber 125 is squeezed into the first air guide groove 1511 and the second air guide groove 1512 due to the pressure difference. The gas in the first air guide groove 1511 enters the first air guide hole 1521 through the first air guide hole 1522. The gas in the liquid storage tank 4 and the second air guide groove 1512 enters the liquid storage tank 4 through the second air guide hole 1522, and is transmitted to the liquid storage tank 4 through the first air guide hole 1521 and the second air guide hole 1522, so that the air pressure in the liquid storage tank 4 is balanced with that in the atomization chamber 125, and then the smoke oil in the liquid storage tank 4 enters the atomizer core 2 through the lower liquid hole 111, so that the smoke oil in the liquid storage tank 4 can be smoothly transmitted to the atomizer core 2 through the lower liquid hole 111, thereby preventing the atomizer core 2 from dry burning.

[0130] In a specific embodiment, when a user draws on the electronic atomization device 100, the atomizer core 2 atomizes the e-liquid. The air pressure of the outside atmosphere is greater than the air pressure of the liquid storage tank 4. Due to the pressure difference, the air of the outside atmosphere is squeezed into the first air guide groove 1511 and the second air guide groove 1512. The gas in the first air guide groove 1511 enters the liquid storage tank 4 through the first air guide hole 1521, and the gas in the second air guide groove 1512 enters the liquid storage tank 4 through the second air guide hole 1522. The gas is transmitted to the liquid storage tank 4 through the first air guide hole 1521 and the second air guide hole 1522, so that the air pressure of the liquid storage tank 4 is balanced with that of the outside atmosphere, and then the e-liquid in the liquid storage tank 4 enters the atomizer core 2 through the lower liquid hole 111. The e-liquid in the liquid storage tank 4 can be smoothly transmitted to the atomizer core 2 through the lower liquid hole 111, thereby preventing the atomizer core 2 from dry burning.

[0131] In a specific embodiment, when a user draws in the electronic atomization device 100, the atomizer core 2 atomizes the e-liquid, and the air pressure in the atomization chamber 125 is greater than the air pressure in the liquid storage tank 4. The atomization chamber 125 is connected to the outside atmosphere, and the air from the outside atmosphere enters the atomization chamber 125 through the air inlet 126. The gas in the atomization chamber 125 is squeezed into the first air guide groove 1511 and the second air guide groove 1512 due to the pressure difference, and the gas in the first air guide groove 1511 enters the liquid storage tank 4 through the first air guide hole 1521. When the amount of gas transmitted by the first air guiding groove 1511 is greater than the amount of gas transmitted by the first air guiding hole 1521, the third air guiding groove 1513 transmits the gas not transmitted in the first air guiding groove 1511 to the liquid storage tank 4 through the lower liquid hole 111. When the amount of gas transmitted by the second air guiding groove 1512 is greater than the amount of gas transmitted by the second air guiding hole 1522, the fourth air guiding groove 1514 transmits the gas not transmitted in the second air guiding groove 1512 to the liquid storage tank 4 through the lower liquid hole 111. Gas is transmitted to the liquid storage tank 4 through the first air guiding hole 1521, the second air guiding hole 1522 and the lower liquid hole 111, so that the air pressure in the liquid storage tank 4 and the atomizing chamber 125 is balanced, and then the smoke oil in the liquid storage tank 4 enters the atomizer core 2 through the lower liquid hole 111, so that the smoke oil in the liquid storage tank 4 can be smoothly transmitted to the atomizer core 2 through the lower liquid hole 111, thereby avoiding dry burning of the atomizer core 2.

[0132] The atomizer 10 further includes a seal 3, which is disposed between the mounting base 1 and the atomizing core 2. The seal 3 may be a sealing ring. The porous substrate 21 may be any one of porous ceramics and porous metals.

[0133] The porous matrix 21 communicates with the liquid stored in the liquid reservoir 4 and absorbs the liquid from the reservoir 4 through capillary action. The heating element 22 is used to heat the liquid in the atomized porous matrix 21. In one embodiment, the porous matrix 21 includes an oil transfer portion 211 and a raised portion 212 integrally formed on one side of the oil transfer portion 211. The leakage buffer structure 122 is in contact with the periphery of the surface of the oil transfer portion 211 on which the raised portion 212 is located. The surface of the raised portion 212 facing away from the oil transfer portion 211 is the atomizing surface 214, while the surface of the oil transfer portion 211 in contact with the e-liquid is the liquid absorbing surface 213. The leakage buffer structure 122 is in contact with the edge of the surface of the oil transfer portion 211 on which the raised portion 212 is located. That is, the leakage buffer structure 122 is arranged in contact with the edge of the oil transfer portion 211 and spaced apart from the raised portion 212. This prevents the leakage buffer structure 122 from being damaged by the high temperature of the heating element 22 on the atomizing surface 214. The atomizing surface 214 is provided with a heating element 22. Specifically, the heating element 22 can be a heating film or a heating circuit. In one embodiment, the heating element 22 is electrically connected to an electrode, one end of which extends through the base 121 and connects to the power supply assembly 202. Specifically, the oil transfer portion 211 and the raised portion 212 are integrally formed, and both the oil transfer portion 211 and the raised portion 212 are made of porous materials. For example, the material of the oil transfer portion 211 and the raised portion 212 can be porous ceramic or porous metal, but is not limited to these two materials, as long as they can transfer the e-liquid in the liquid reservoir 4 to the heating element 22 for atomization through capillary action. The oil transfer portion 211 only partially covers the leakage buffer structure 122. The capillary force of the porous matrix 21 is greater than that of the leakage buffer structure 122. When the heating element 22 heats the liquid in the atomized porous matrix 21, the liquid received by the leakage buffer structure 122 can flow back into the porous matrix 21 and be heated and atomized.

[0134] The mounting base 1 has an atomizing chamber 125, in which the atomizing core 2 is housed. The liquid leakage buffer structure 122 is connected to the bottom of the atomizing chamber 125 and absorbs the accumulated liquid at the bottom of the atomizing chamber 125 through capillary force. The mounting base 1 includes an upper body 11 and a lower body 12. The lower body 12 includes a base 121. The upper body 11 is provided with a lower liquid hole 111. The liquid in the liquid storage tank 4 flows to the porous base 21 through the lower liquid hole 111. The liquid leakage buffer structure 122 is provided on the lower body 12. The porous base 21 includes a liquid absorption surface 213 and an atomizing surface 214. The liquid absorption surface 213 is connected to the lower liquid hole 111. The heating element 22 is provided on the atomizing surface 214. The porous base 21 is in contact with the liquid leakage buffer structure 122.

[0135] Among them, when the pressure of the liquid storage tank 4 increases, the pressure of the liquid storage tank 4 is greater than the pressure of the atomization chamber 125, and the pressure difference between the liquid storage tank 4 and the atomization chamber 125 squeezes the liquid in the liquid storage tank 4 to the porous matrix 21, causing excess liquid to overflow from the porous matrix 21, and the leakage buffer structure 122 receives and locks the overflowing excess liquid; when the pressure of the liquid storage tank 4 decreases, the pressure of the liquid storage tank 4 is less than the pressure of the atomization chamber 125, and the pressure difference between the liquid storage tank 4 and the atomization chamber 125 causes the liquid in the leakage buffer structure 122 to flow back to the porous matrix 21 in contact with it through capillary action, and the porous matrix 21 returns the liquid therein to the liquid storage tank 4.

[0136] In this embodiment, the upper body 11 and the lower body 12 are made as one piece, and a slot 112 can also be provided on the upper body 11. A clip 124 is provided on the outer wall of the lower body 12 for engaging with the slot 112 on the upper body 11 to fix the lower body 12 to the upper body 11.

[0137] The material of the leakage buffer structure 122 is a porous material, which can be a hard porous material or a soft porous material.

[0138] When the leakage buffer structure 122 is made of a hard porous material, in order to save space, the leakage buffer structure 122 can also be used to support the atomizer core 2. The hard porous material can be at least one of porous ceramics and porous metals, or other materials with supporting and liquid absorbing capabilities.

[0139] See also Figure 22 , Figure 22This is a schematic diagram of the first embodiment of the leakage buffer structure provided by the present invention. In one specific embodiment, the leakage buffer structure 122 includes two spaced-apart sub-leakage buffers 1221. The sub-leakage buffers 1221 are made of a hard, porous material, such as porous ceramic or porous metal, that has both support and liquid absorption capabilities. Therefore, they can serve as the support 127 for the atomizer core 2. It is understood that if the atomizer core 2 is secured by other components, the sub-leakage buffers 1221 may not be used to support the atomizer core 2. When the pressure in the liquid reservoir 4 is greater than the pressure in the atomizer chamber 125, the sub-leakage buffers 1221 can collect e-liquid leaking from the porous matrix 21. When the pressure in the liquid reservoir 4 is less than the pressure in the atomizer chamber 125, the e-liquid stored in the sub-leakage buffers 1221 can flow back to the porous matrix 21 in contact therewith, thereby effectively utilizing the leaked e-liquid and enabling the leakage buffer structure 122 to collect and recirculate e-liquid multiple times. The porous material forming the leakage buffer structure 122 has a lower liquid absorption capacity than the porous material forming the oil transfer portion 211. The condensate collection structure 14 and the ventilation channel 15 are in communication with the sub-leakage buffer structure 122. Liquid collected in the condensate collection structure 14 flows back through the sub-leakage buffer structure 122 to the porous substrate 21 in contact therewith.

[0140] See also Figure 23 , Figure 23 A schematic structural diagram of the second embodiment of the leakage buffer structure provided by the present invention. In another specific embodiment, the leakage buffer structure 122 is U-shaped and the material is a hard porous material. Specifically, the leakage buffer structure 122 includes a sub-leakage buffer 1221 and a connecting portion 1222 connecting the sub-leakage buffer 1221 away from the end of the porous matrix 21. The material of the sub-leakage buffer 1221 and the connecting portion 1222 is a porous material, for example, it can be a material with supporting and liquid absorption capabilities such as porous ceramics and porous metals. The connecting portion 1222 is provided with a channel that matches the air inlet 126 provided on the base 121. The connecting portion 1222 is used to absorb the condensed smoke oil after the atomized smoke oil is condensed in the atomizing chamber 125 formed by the leakage buffer structure 122 and the atomizing core 2, to prevent the condensed smoke oil from leaking through the air inlet 126. The condensate collecting structure 14 and the ventilation channel 15 are in communication with the sub-leakage buffer 1221 and / or the connector. The liquid collected in the condensate collecting structure 14 flows back to the porous matrix 21 in contact therewith through the leakage buffer structure 122 .

[0141] See also Figure 24 , Figure 24This is a schematic structural diagram of the third embodiment of the liquid leakage buffer structure provided by the present invention. A main body 123 is provided on the lower base 12, and the main body 123 includes a first sub-body 1231 and a second sub-body 1232. The first sub-body 1231 and the second sub-body 1232 are spaced apart and symmetrically arranged. The first sub-body 1231 and the second sub-body 1232 can be arranged parallel and perpendicular to the base 121. In another optional embodiment, the first sub-body 1231 and the second sub-body 1232 can be tilted and symmetrically arranged on the base 121, and the distance between the ends of the first sub-body 1231 and the second sub-body 1232 away from the base 121 is greater than the distance between the ends of the first sub-body 1231 and the second sub-body 1232 connected to the base 121. The material of the first sub-body 1231 and the second sub-body 1232 is dense ceramic, dense metal or glass material, or other materials with support capacity but no liquid absorption capacity. In another specific embodiment, the leakage buffer structure 122 is disposed at the ends of the first and second sub-bodies 1231, 1232, distal from the base 121. The ends of the first and second sub-bodies 1231, 1232, distal from the base 121, are connected to the oil transfer unit 211 via the leakage buffer structure 122. The leakage buffer structure 122 can be made of a porous material with both support and absorbency. For example, the material of the leakage buffer structure 122 can be porous ceramic, porous metal, or other materials with both support and absorbency. The leakage buffer structure 122 can collect liquid leaked from the oil transfer unit 211 within the leakage buffer structure 122, or it can return stored liquid within the leakage buffer structure 122 to the oil transfer unit 211 in contact with the leakage buffer structure 122, thereby effectively utilizing the stored liquid and enabling multiple cycles of collection and return of the liquid. The leakage buffer structure 122 can also be made of materials with absorbency but no support, such as cotton, fiber, or absorbent resin. The porous material forming the leakage buffer structure 122 has a lower liquid absorption capacity than the porous material forming the oil transfer portion 211. The condensate collection structure 14 and the ventilation channel 15 are in communication with the leakage buffer structure 122. Liquid collected in the condensate collection structure 14 flows back through the leakage buffer structure 122 to the porous substrate 21 in contact therewith.

[0142] The leakage buffer structure 122 is made of a soft porous material and is supported by a support portion 127, with one end of the leakage buffer structure 122 in contact with the porous base 21 and the other end extending to the bottom of the atomization chamber 125. The soft porous material is at least one of cotton, fiber, and resin, and may also be other materials that have liquid absorption capabilities but no support capabilities.

[0143] See also Figure 25 and Figure 26 , Figure 25 A schematic structural diagram of a fourth embodiment of the liquid leakage buffer structure provided by the present invention; Figure 26 yes Figure 25A top view of the leakage buffer structure is provided. In a specific embodiment, the material of the leakage buffer structure 122 is a soft porous material. The anti-leakage liquid absorbing member 1227 is supported by the support portion 127, so that one end of the leakage buffer structure 122 contacts the porous matrix 21, and the other end extends to the bottom of the atomization chamber 125. The support portion 127 includes a first sub-support member 1271 and a second sub-support member 1272. A guide channel 1233 is provided on the first sub-support member 1271 and the second sub-support member 1272, and the leakage buffer structure 122 is provided in the guide channel 1233. One end of the leakage buffer structure 122 contacts the oil transfer portion 211 in the porous matrix 21, and the other end extends to the base 121 of the lower seat 12. The guide channel 1233 can be a groove structure, and the groove size of the guide channel 1233 is larger than the size of the first capillary groove 1223. The opening 31 at one end of the diversion channel 1233 is located on the inner sidewalls of the first and second sub-support members 1271 and 1272, while the opening 31 at the other end is located on the end surfaces of the first and second sub-support members 1271 and 1272 away from the base 121. The leakage buffer structure 122 filled in the diversion channel 1233 contacts the oil transfer portion 211. The cross-sectional dimensions of the grooves provided on the surfaces of the first and second sub-support members 1271 and 1272 away from the base 121 are no less than the contact dimension between the oil transfer portion 211 and the first and second sub-support members 1271 and 1272. Specifically, the width of the opening 31 of the flow channel 1233 at the end surfaces of the first and second sub-support members 1271 and 1272, in the direction of the line connecting the first and second sub-support members 1271 and 1272, is no less than the contact width between the first and second sub-support members 1271 and 1272 and the oil transfer unit 211 in the direction of the line connecting the first and second sub-support members 1271 and 1272. A leakage buffer structure 122 is disposed in the flow channel 1233 and extends from the end of the flow channel 1233. One end of the leakage buffer structure 122 is connected to the oil transfer unit 211, and the other end extends between the first and second sub-support members 1271 and 1272, or alternatively, to the surface of the base 121. This structure collects condensed atomized liquid and prevents it from leaking out of the air inlet 126 provided on the base 121 after cooling and liquefaction, thereby affecting the user experience. When the pressure in the liquid storage tank 4 decreases, the leakage buffer structure 122 can also return the collected smoke liquid to the oil transfer unit 211 through capillary action, thereby effectively utilizing the leaked liquid and enabling the leakage buffer structure 122 to collect and return smoke liquid multiple times. The liquid absorption capacity of the leakage buffer structure 122 is less than that of the oil transfer unit 211. Specifically, the porous material comprising the leakage buffer structure 122 has a smaller absorption capacity than that of the porous material comprising the oil transfer unit 211. The leakage buffer structure 122 can be made of absorbent materials such as cotton, fiber, and absorbent resin.The condensate collecting structure 14 and the ventilation channel 15 are in communication with the leakage buffer structure 122 , and the liquid collected in the condensate collecting structure 14 flows back through the leakage buffer structure 122 to the porous matrix 21 in contact therewith.

[0144] When the temperature rises, the volume of bubbles in the liquid in the liquid storage tank 4 expands, increasing the pressure in the liquid storage tank 4, which in turn causes the liquid in the atomizer core 2 to leak out from the end of the oil transfer portion 211 of the atomizer core 2. The leaked liquid from the oil transfer portion 211 can flow to the leakage buffer structure 122 connected to the oil transfer portion 211. The leakage buffer structure 122 is used to collect the leaked liquid. The liquid can penetrate along the extension direction of the leakage buffer structure 122, preventing the liquid from leaking out of the air inlet 126. When the temperature drops, the atomized liquid in the atomization chamber 125 cools and forms liquid, which flows onto the base 121 and is collected by the leakage buffer structure 122 extending to the surface of the base 121. At the same time, the volume of the bubbles in the liquid storage tank 4 will shrink, which will reduce the pressure of the liquid storage tank 4. Furthermore, due to the pressure difference between the inside and outside of the liquid storage tank 4, the liquid collected and stored in the leakage buffer structure 122 will flow to the oil transfer part 211 connected to the leakage buffer structure 122 through capillary action along the leakage buffer structure 122 in the direction close to the oil transfer part 211, thereby realizing the effective utilization of the collected liquid.

[0145] See also Figure 27 , Figure 27 Schematic diagram of the structure of the fifth embodiment of the leakage buffer structure provided by the present invention. In a specific embodiment, the leakage buffer structure 122 includes a body 123 and a first capillary groove 1223 provided on the body 123. The first capillary groove 1223 can be provided on any side surface of the body 123, and the opening 31 can face any direction, as long as it can absorb and store leakage. Preferably, the opening 31 of the first capillary groove 1223 faces the atomizing chamber 125. The body 123 is provided on the surface of the base 121 close to the upper body 11 and is fixedly connected to the base 121. The body 123 can be arranged perpendicular to the surface of the base 121 and integrally formed. One end of the body 123 away from the base 121 contacts the oil transfer portion 211, so that the first capillary groove 1223 extends on the body 123 in a direction away from the bottom of the atomizing chamber 125 or the base 121 and contacts the oil transfer portion 211, and the other end extends in a direction close to the bottom of the atomizing chamber 125 or the base 121. First capillary groove 1223 is used to store liquid leaking from oil transfer portion 211 and return it to liquid storage tank 4, thereby preventing leakage and effectively utilizing the stored liquid. Condensate collection structure 14 and ventilation channel 15 are connected to first capillary groove 1223. Liquid leaking from condensate collection structure 14 and ventilation channel 15 is collected by leakage buffer structure 122, which then flows back to porous substrate 21 in contact with it.

[0146] Among them, a plurality of first capillary grooves 1223 are provided on the side wall surfaces of the first sub-body 1231 and the second sub-body 1232 close to the atomization chamber 125. The plurality of first capillary grooves 1223 arranged side by side form a liquid leakage buffer structure 122. Specifically, the cross-section of the first capillary groove 1223 can be U-shaped, or V-shaped, semi-circular, semi-elliptical, or C-shaped. The shape of its cross-section is not limited here, as long as it can facilitate drainage and collection. In an optional embodiment, the size of the first capillary groove 1223 is not less than the contact size between the first capillary groove 1223 and the atomization core 2. Among them, this size is the width in the direction of the first sub-body 1231 and the second sub-body 1232.

[0147] The bottom of the atomization chamber 125 is the surface of the base 121 connected to the liquid leakage buffer structure 122. A second capillary groove 1224 is provided on the surface of the base 121 connected to the liquid leakage buffer structure 122. The second capillary groove 1224 is arranged on the surface of the base 121 between the first sub-body 1231 and the second sub-body 1232 and is connected to the first capillary groove 1223. The first capillary groove 1223 and the second capillary groove 1224 form a capillary groove with an L-shaped structure. Specifically, the cross-sectional shape of the second capillary groove 1224 can be the same as or different from the cross-sectional shape of the structure of the first capillary groove 1223. The number of the second capillary grooves 1224 can be one, that is, one second capillary groove 1224 is connected to all the first capillary grooves 1223 on the first sub-body 1231 or the second sub-body 1232. The number of the second capillary grooves 1224 can be the same as the number of the first capillary grooves 1223, that is, one first capillary groove 1223 is connected to a corresponding one second capillary groove 1224. The first capillary groove 1223 can make the e-liquid leaked from the end of the oil transfer part 211 flow along the extending direction of the first capillary groove 1223 to the second capillary groove 1224, store the leaked e-liquid, and prevent the e-liquid from leaking out through the air inlet holes 126 provided on the base 121. Among them, the second capillary groove 1224 can also collect the condensate after the atomized e-liquid is cooled, and prevent the atomized e-liquid from leaking out through the air inlet holes 126 provided on the base 121 after cooling and liquefying, which affects the user experience. The first capillary groove 1223 can also return the collected e-liquid to the oil transfer part 211 in contact with it through capillary action, thereby realizing the effective utilization of the collected leaked liquid. Among them, the liquid absorption capacity of the first capillary groove 1223 and the second capillary groove 1224 is less than the liquid absorption capacity of the oil transfer part 211. Specifically, the liquid absorption capacity of the first capillary groove 1223 and the second capillary groove 1224 is less than the liquid absorption capacity of the porous material made into the oil transfer part 211. The condensate collection structure 14 and the ventilation channel structure 15 are connected to the first capillary groove 1223 and / or the second capillary groove 1224. The liquid leaked from the condensate collection structure 14 and the ventilation channel structure 15 is collected by the second capillary groove, and the second capillary groove 1224 returns to the first capillary groove 1223 and then returns to the porous matrix 21 in contact with the first capillary groove 1223.

[0148] In another specific embodiment, the leakage buffer structure 122 also supports the atomizer coil 2. Specifically, to save space, the first sub-body 1231 and the second sub-body 1232, each provided with the first capillary groove 1223, also support the atomizer coil 2. The ends of the first and second sub-bodies 1231, 1232 facing away from the base 121 support the atomizer coil 2. The oil transfer portion 211 covers the ends of the first and second sub-bodies 1231, 1232 facing away from the base 121. A raised portion 212 provided on one side of the oil transfer portion 211 is disposed between the first and second sub-bodies 1231, 1232.

[0149] See 28, Figure 28 This is a schematic diagram of the phenomenon of the atomizer provided by the present invention during the heating process. As the temperature rises, the volume of the bubbles in the liquid storage tank 4 will expand, causing the pressure in the liquid storage tank 4 to increase, thereby causing the liquid in the atomizer core 2 to leak out from the end of the oil transfer portion 211 in the atomizer core 2. The leaked liquid at the end of the oil transfer portion 211 can flow to the first capillary groove 1223 connected to the oil transfer portion 211, and the leaked liquid is collected by the first capillary groove 1223. The liquid can then flow along the first capillary groove 1223 provided on the first sub-body 1231 and the second sub-body 1232 to the second capillary groove 1224, and the leaked liquid is collected by the first capillary groove 1223 and the second capillary groove 1224, thereby preventing the leaked liquid from leaking out of the air inlet 126. Please refer to 29, Figure 29 This is a schematic diagram of the phenomenon occurring during the cooling process of the atomizer provided by the present invention. As the temperature decreases, the atomized tobacco liquid in the atomization chamber 125, which is composed of the first sub-body 1231, the second sub-body 1232, the base 121, and the atomizer core 2, cools to form tobacco liquid, which then flows onto the base 121 and is collected by the second capillary groove 1224. Simultaneously, the volume of bubbles in the tobacco liquid in the liquid reservoir 4 decreases, reducing the pressure in the reservoir 4. Consequently, due to the pressure differential between the inside and outside of the reservoir 4, the tobacco liquid collected and stored in the first capillary groove 1223 and the second capillary groove 1224 flows through capillary action along the first capillary groove 1223, away from the second capillary groove 1224, to the oil transfer portion 211 connected to the first capillary groove 1223. Because the liquid absorption capacity of the oil transfer portion 211 is greater than that of the first and second capillary grooves 1223 and 1224, the oil transfer portion 211 can absorb the tobacco liquid and effectively utilize the collected tobacco liquid.

The liquid leakage buffer structure 122 includes a main body 123 and capillary pores 1225 provided on the main body 123. A plurality of capillary pores 1225 are provided on the first sub-body 1231 and the second sub-body 1232. One end of the capillary pore 1225 extends in a direction away from the bottom of the atomization chamber 125 on the main body and contacts the porous matrix 21, and the other end extends in a direction close to the bottom of the atomization chamber 125. Specifically, the cross-sectional shape of the capillary pore 1225 structure can be rectangular, or triangular, circular, semi-circular, elliptical. The cross-sectional shape thereof is not limited herein, as long as it is a shape convenient for drainage and collection. In an optional embodiment, the distribution width of the capillary pores 1225 on the end surface of the first sub-body 1231 and the second sub-body 1232 contacting the porous matrix 21 is not less than the contact width of the first sub-body 1231 and the second sub-body 1232 with the porous matrix 21. This width is in the direction of the connection line of the first sub-body 1231 and the second sub-body 1232. The surface of the base 121 connected to the main body 123 is provided with a second capillary groove 1224. The second capillary groove 1224 is provided on the surface of the base 121 between the first sub-body 1231 and the second sub-body 1232 and is communicated with the capillary pore 1225 structure. Specifically, the cross-sectional shape of the second capillary groove 1224 can be U-shaped, or V-shaped, semi-circular, elliptical, or C-shaped. The cross-sectional shape thereof is not limited herein, as long as it is a shape convenient for collection. The number of the capillary pores 1225 can be one, that is, one second capillary groove 1224 is communicated with all the capillary pores 1225 on the first sub-body 1231 or the second sub-body 1232. The number of the second capillary grooves 1224 can be the same as the number of the capillary pores 1225, that is, one capillary pore 1225 is communicated with a corresponding second capillary groove 1224. The leaked e-liquid can flow along the capillary pores 1225 to the second capillary groove 1224 to store the leaked e-liquid and prevent the e-liquid from leaking out through the air inlet hole 126 provided on the base 121. Among them, the second capillary groove 1224 can also collect the condensate after the atomized e-liquid is cooled, and prevent the atomized e-liquid from leaking out through the air inlet hole 126 provided on the base 121 after cooling and liquefying, which affects the user experience. The capillary pores 1225 can also reflux the collected e-liquid back to the oil transmission part 211 contacting it through capillary action, thereby realizing the effective utilization of the collected liquid leakage and prolonging the service time of the second capillary groove 1224. Among them, the liquid absorption capacity of the capillary pores 1225 and the second capillary groove 1224 is less than the liquid absorption capacity of the oil transmission part 211. Specifically, the liquid absorption capacity of the capillary pores 1225 and the second capillary groove 1224 is less than the liquid absorption capacity of the porous material making up the oil transmission part 211.The condensate collection structure 14 and the ventilation channel 15 are connected to the capillary pores 1225 and / or the second capillary grooves 1224. The liquid leaked from the condensate collection structure 14 and the ventilation channel 15 is collected by the second capillary grooves 1224, and the second capillary grooves 1224 flow back to the capillary pores 1225, and then flow back to the porous matrix 21 in contact with the capillary pores 1225.

[0151] When the temperature rises, the bubbles in the liquid reservoir 4 expand, increasing the pressure in the reservoir 4 and causing the liquid in the atomizer core 2 to leak out from the end of the oil transfer portion 211 of the atomizer core 2. The leaked liquid can flow to the capillary pores 1225 connected to the oil transfer portion 211, where it is collected by the capillary pores 1225. The liquid can then flow along the capillary pores 1225 provided on the first and second sub-bodies 1231 and 1232 to the second capillary grooves 1224, where it is collected and prevented from leaking out of the air inlet 126. When the temperature drops, the atomized liquid in the atomizer chamber 125 cools and forms liquid, which then flows to the base 121 and is collected by the second capillary grooves 1224. At the same time, the volume of the bubbles in the smoke oil in the liquid storage tank 4 will shrink, causing the pressure in the liquid storage tank 4 to decrease. As a result, due to the pressure difference between the inside and outside of the liquid storage tank 4, the smoke oil collected and stored in the capillary pores 1225 and the second capillary grooves 1224 will flow through capillary action along the capillary pores 1225 away from the second capillary grooves 1224 to the oil transfer part 211 connected to the capillary pores 1225. Since the liquid absorption capacity of the oil transfer part 211 is greater than the liquid absorption capacity of the capillary pores 1225 and the second capillary grooves 1224, the oil transfer part 211 can absorb the smoke oil and realize the effective utilization of the collected smoke oil.

[0152] In another optional embodiment, the leakage buffer structure 122 includes a first capillary groove 1223 and a soft porous material. The soft porous material is filled in the first capillary groove 1223. The liquid absorption capacity of the first capillary groove 1223 and the soft porous material is less than the liquid absorption capacity of the porous matrix 21. The condensate collection structure 14 and the ventilation channel 15 are connected to the soft porous material and / or the first capillary groove 1223. Liquid leaked from the condensate collection structure 14 and the ventilation channel 15 is collected by the first capillary groove 1223 and / or the porous material and then flows back to the porous matrix 21 in contact with the first capillary groove 1223 and / or the porous material.

[0153] In another optional embodiment, the leakage buffer structure 122 includes capillary pores 1225 and a soft porous material. The capillary pores 1225 are filled with the soft porous material. The liquid absorption capacity of the capillary pores 1225 and the soft porous material is less than the liquid absorption capacity of the porous matrix 21. The condensate collection structure 14 and the ventilation channel 15 are connected to the soft porous material and / or the capillary pores 1225. Liquid leaking from the condensate collection structure 14 and the ventilation channel 15 is collected by the capillary pores 1225 and / or the porous material and then flows back to the porous matrix 21 in contact with the capillary pores 1225 and / or the porous material.
