[0096] In another optional embodiment, one of the ends of the first air guide groove 1511 is in communication with the atomization cavity 125 or the external air, and the other of the ends is in communication with the first air guide hole 1521.

[0097] The liquid in the liquid storage tank 4 flows to the atomization core 2 via the liquid flowing hole 111. If the air pressure in the liquid storage tank 4 decreases, a speed at which the liquid in the liquid storage tank 4 flows to the atomization core 2 through the liquid flowing hole 111 is less than a speed at which the atomization core 2 atomizes the liquid. Air is transmitted to the liquid storage tank 4 via the air exchange channel 15, to balance the air pressure in the liquid storage tank 4 and the external air pressure.

[0098] In a specific embodiment, the user inhales the electronic atomization device 100. The atomization core 2 atomizes cigarette liquid, the air pressure in the atomization cavity 125 is greater than the air pressure in the liquid storage tank 4, the atomization cavity 125 is in communication with the external air, and the external air enters the atomization cavity 125 via the air inlet hole 126. The air in the atomization cavity 125 is pressed into the first air guide groove 1511 and the second air guide groove 1512 due to an air pressure difference, the air in the first air guide groove 1511 enters the liquid storage tank 4 via the first air guide hole 1521, the air in the second air guide groove 1512 enters the liquid storage tank 4 via the second air guide hole 1522, and the air is transmitted to the liquid storage tank 4 via the first air guide hole 1521 and the second air guide hole 1522. Therefore, the air pressure in the liquid storage tank 4 and the air pressure in the atomization cavity 125 are balanced, and the cigarette liquid in the liquid storage tank 4 further enters the atomization core 2 via the liquid flowing hole 111, so that the cigarette liquid in the liquid storage tank 4 can be smoothly transmitted to the atomization core 2 via the liquid flowing hole 111, thereby avoiding dry burning of the atomization core 2.

[0099] In a specific embodiment, the user inhales the electronic atomization device 100. The atomization core 2 atomizes cigarette liquid, the external air pressure is greater than the air pressure in the liquid storage tank 4, and the external air is pressed into the first air guide groove 1511 and the second air guide groove 1512 due to an air pressure difference. The air in the first air guide groove 1511 enters the liquid storage tank 4 via the first air guide hole 1521, the air in the second air guide groove 1512 enters the liquid storage tank 4 via the second air guide hole 1522, and the air is transmitted to the liquid storage tank 4 via the first air guide hole 1521 and the second air guide hole 1522. Therefore, the air pressure in the liquid storage tank 4 and the external air pressure are balanced, and the cigarette liquid in the liquid storage tank 4 further enters the atomization core 2 via the liquid flowing hole 111, so that the cigarette liquid in the liquid storage tank 4 can be smoothly transmitted to the atomization core 2 via the liquid flowing hole 111, thereby avoiding dry burning of the atomization core 2.

[0100] In a specific embodiment, the user inhales the electronic atomization device 100. The atomization core 2 atomizes cigarette liquid, the air pressure in the atomization cavity 125 is greater than the air pressure in the liquid storage tank 4, the atomization cavity 125 is in communication with the external air, the external air enters the atomization cavity 125 via the air inlet hole 126, the air in the atomization cavity 125 is pressed into the first air guide groove 1511 and the second air guide groove 1512 due to an air pressure difference, and the air in the first air guide groove 1511 enters the liquid storage tank 4 via the first air guide hole 1521. When an amount of the air transmitted by the first air guide groove 1511 is greater than an amount of the air transmitted by the first air guide hole 1521, the third air guide groove 1513 transmits air that is not transmitted in the first air guide groove 1511 to the liquid storage tank 4 via the liquid flowing hole 111. When an amount of the air transmitted by the second air guide groove 1512 is greater than an amount of the air transmitted by the second air guide hole 1522, the fourth air guide groove 1514 transmits air that is not transmitted in the second air guide groove 1512 to the liquid storage tank 4 through the liquid flowing hole 111. Since the first air guide hole 1521, the second air guide hole 1522, and the liquid flowing hole 111 transmit air to the liquid storage tank 4, the air pressure in the liquid storage tank 4 and the air pressure in the atomization cavity 125 are balanced, and the cigarette liquid in the liquid storage tank 4 further enters the atomization core 2 via the liquid flowing hole 111, so that the cigarette liquid in the liquid storage tank 4 can be smoothly transmitted to the atomization core 2 via the liquid flowing hole 111, thereby avoiding dry burning of the atomization core 2.

[0101] The atomizer 10 further includes a seal member 3, and the seal member 3 is provided between the mounting base 1 and the atomization core 2. The seal member 3 may be a seal ring. The porous substrate 21 is made of any one of a porous ceramic or a porous metal.

[0102] The porous substrate 21 is in communication with the liquid stored in the storage tank 4 and absorbs liquid from the liquid storage tank 4 by a capillary force; and the heating element 22 is configured to heat and atomize the liquid of the porous substrate 21. In an embodiment, the porous substrate 21 includes an cigarette liquid transmission portion 211 and a protruding portion 212 integrally formed on one side of the cigarette liquid transmission portion 211, and the leaked liquid buffer structure 122 is in contact with a periphery of one side surface of the cigarette liquid transmission portion 211 provided with the protruding portion 212. A surface of the protruding portion 212 away from the cigarette liquid transmission portion 211 is a atomization surface 214, a surface of the cigarette liquid transmission portion 211 in contact with cigarette liquid is a liquid absorbing surface 213, and the leaked liquid buffer structure 122 is in contact with an edge of the side surface of the cigarette liquid transmission portion 211 provided with the protruding portion 212. That is, the leaked liquid buffer structure 122 is provided in contact with an edge of the cigarette liquid transmission portion 211 and is provided at intervals with the protruding portion 212, so that the leaked liquid buffer structure 122 can be prevented from being damaged by high temperature of the heating element 22 on the atomization surface 214. The heating element 22 is provided on the atomization surface 214. Specifically, the heating element 22 may be a heating film or may be a heating circuit. In a specific embodiment, the heating element 22 is electrically connected to an electrode, and one end of the electrode passes through a foundation base 121 to be connected to the power supply assembly 202. Specifically, the cigarette liquid transmission portion 211 and the protruding portion 212 are integrally formed, and the cigarette liquid transmission portion 211 and the protruding portion 212 are both made of porous materials. For example, the materials of the cigarette liquid transmission portion 211 and the protruding portion 212 may be a porous ceramic or a porous metal, but are not limited to the two materials, provided that the cigarette liquid in the liquid storage tank 4 can be transmitted to the heating element 22 through capillary action for atomization. The cigarette liquid transmission portion 211 only covers a part of the leaked liquid buffer structure 122. The capillary force of the porous substrate 21 is greater than the capillary force of the leaked liquid buffer structure 122, and when the heating element 22 heats and atomizes the liquid of the porous substrate 21, the liquid received by the leaked liquid buffer structure 122 may reflux to the porous substrate 21 and is heated and atomized.

[0103] The mounting base 1 includes the atomization cavity 125, the atomization core 2 is accommodated in the atomization cavity 125, and the leaked liquid buffer structure 122 is connected to the bottom of the atomization cavity 125 and absorbs liquid deposited at the bottom of the atomization cavity 125 by a capillary force. The mounting base 1 includes the upper base body 11 and the lower base body 12. The lower base body 12 includes the foundation base 121, the liquid flowing hole 111 is provided on the upper base body 11, the cigarette liquid in the liquid storage tank 4 flows to the porous substrate 21 through the liquid flowing hole 111. The leaked liquid buffer structure 122 is provided on the lower base body 12, the porous substrate 21 includes the liquid absorbing surface 213 and the atomization surface 214, the liquid absorbing surface 213 is connected to the liquid flowing hole 111, the heating element 22 is provided on the atomization surface 214, and the porous substrate 21 is in contact with the leaked liquid buffer structure 122.

[0104] When the air pressure in the liquid storage tank 4 increases, the air pressure in the liquid storage tank 4 is greater than the air pressure in the atomization cavity 125, an air pressure difference between the liquid storage tank 4 and the atomization cavity 125 presses the liquid in the liquid storage tank 4 to the porous substrate 21, so that redundant liquid overflows from the porous substrate 21, and the leaked liquid buffer structure 122 receives and locks the overflowed redundant liquid. When the air pressure in the liquid storage tank 4 decreases, the air pressure in the liquid storage tank 4 is less than the air pressure in the atomization cavity 125, the air pressure difference between the liquid storage tank 4 and the atomization cavity 125 enables the liquid in the leaked liquid buffer structure 122 to reflux to the porous substrate 21 in contact with the leaked liquid buffer structure through capillary action, and the porous substrate 21 refluxes the liquid to the liquid storage tank 4.

[0105] In this embodiment, the upper base body 11 and the lower base body 12 are integrally formed. Alternatively, a groove 112 may be provided on the upper base body 11, and a clamp member 124 is provided on an outer side wall of the lower base body 12 and is configured to be clamped to the groove 112 on the upper base body 11, so that the lower base body 12 is fixedly connected to the upper base body 11.

[0106] A material of the leaked liquid buffer structure 122 is a porous material, and the porous material may be a hard porous material or may be a soft porous material.

[0107] When the material of the leaked liquid buffer structure 122 is a hard porous material, to save space, the leaked liquid buffer structure 122 can be also configured to support the atomization core 2. The hard porous material is at least one of a porous ceramic or a porous metal, or may be another material with a supporting capability and a liquid absorbing capability.

It may be understood that, if the atomization core 2 is fixed through another component, the leaked liquid buffer sub-member 1221 may not be configured to support the atomization core 2. When the air pressure in the liquid storage tank 4 is greater than the air pressure in the atomization cavity 125, the leaked liquid buffer sub-member 1221 can collect cigarette liquid leaked from the porous substrate 21. When the air pressure in the liquid storage tank 4 is less than the air pressure in the atomization cavity 125, the cigarette liquid stored in the leaked liquid buffer sub-member 1221 can reflux to the porous substrate 21 in contact with the leaked liquid buffer sub-member, to further effectively utilize the leaked cigarette liquid, so that the leaked liquid buffer structure 122 can implement cyclic collection and reflux of cigarette liquid for a plurality of times. The liquid absorbing capability of the porous material forming the leaked liquid buffer structure 122 is less than the liquid absorbing capability of the porous material forming the cigarette liquid transmission portion 211. The condensate collecting structure 14 and the air exchange channel 15 are in communication with the leaked liquid buffer structure 122, and the liquid collected in the condensate collecting structure 14 refluxes to the porous substrate 21 in contact with the leaked liquid buffer structure through the leaked liquid buffer structure 122.

Specifically, the leaked liquid buffer structure 122 includes a leaked liquid buffer sub-member 1221 and a connecting portion 1222 connected to the leaked liquid buffer sub-member 1221 and away from an end portion of the porous substrate 21. Materials of the leaked liquid buffer sub-member 1221 and the connecting portion 1222 are porous materials, for example, may be materials such as a porous ceramic or a porous metal with a supporting capability and a liquid absorbing capability. A duct matching the air inlet hole 126 provided on the foundation base 121 is provided on the connecting portion 1222. The connecting portion 1222 is configured to absorb condensed cigarette liquid after atomized cigarette liquid in the atomization cavity 125 formed by the leaked liquid buffer structure 122 and the atomization core 2 is condensed, to prevent the condensed cigarette liquid from leaking out through the air inlet hole 126. The condensate collecting structure 14 and the air exchange channel 15 are in communication with the leaked liquid buffer sub-member 1221 and/or the connecting portion, and the liquid collected in the condensate collecting structure 14 refluxes to the porous substrate 21 in contact with the leaked liquid buffer structure through the leaked liquid buffer structure 122.
