The mist re-atomizing chamber 121 is mixed with air and then carried out. The atomizing assembly 130 is not limited to the illustrated configuration and other configurations conventional in the art may be used.

The liquid storage case 140 may have a cylindrical shape, and includes a bottom wall 142 and a cylindrical side wall 143 having one end connected to the periphery of the bottom wall 142, and the other end of the side wall 143 forms an opening. The opening is nested within the atomizing assembly 130. The sidewall 143 is formed with an inlet port 1430, and the inlet port 1430 is provided corresponding to the gas-liquid equilibrium element 150.

Referring to fig. 6 to 8, the gas-liquid balance element 150 may be cylindrical in some embodiments, and may be axially inserted into the liquid storage case 140, and the outer sidewall surface of the gas-liquid balance element is closely attached to the inner wall surface of the sidewall 143 of the liquid storage case 140; that is, the liquid storage case 140 has a section forming a cavity for accommodating the gas-liquid balance element 150, and the cavity is communicated with the liquid storage chamber 141, so that the gas-liquid balance element 150 is communicated with the liquid storage chamber 141. The gas-liquid balance member 150 has a space from the bottom wall 142 of the reservoir 140, and the space forms the reservoir cavity 141 of the reservoir 140. The gas-liquid balance element 150 is disposed between the liquid storage cavity 141 and the atomizing assembly 130, and is communicated with the gas inlet 1430 on the liquid storage case 140 to supplement gas to the liquid storage cavity 141 (as shown by an arrow in fig. 4), and has a liquid storage effect.

The vapor-liquid balancing member 150 may include a central shaft 156, and a set of first fins 151 disposed in parallel and spaced apart in the axial direction and a set of second fins 152 disposed in parallel and spaced apart in the axial direction, disposed at the periphery of the central shaft 156, the first fins 151 being adjacent to the reservoir 141 and the second fins 152 being remote from the reservoir 141.

The gas-liquid balancing member 150 may further include a first partition 157 located at an upper portion of the center shaft 156, a second partition 158 located at a middle portion of the center shaft 156, and a third partition 159 located at a lower portion of the center shaft 156, the first fin 151 being disposed between the first partition 157 and the second partition 158, and the second fin 152 being disposed between the second partition 158 and the third partition 159. The thicknesses of the first partition 157, the second partition 158, and the third partition 159 are much greater than those of the first and

second fins

151 and 152. The gas-liquid balancing member 150 may further include a fourth partition 155 located below the third partition 159 in some embodiments, and a space is provided between the fourth partition 155 and the third partition 159. The top surface of the first partition 157 is exposed to the liquid storage chamber 141.

The central shaft 156 has a central through hole 1560 for the passage of the drainage element 160. First liquid storage tanks 1510 penetrating through the outer circumferential surface are formed between the adjacent first fins 151, and second liquid storage tanks 1520 penetrating through the outer circumferential surface are formed between the adjacent second fins 152. The thickness of the first and

second fins

151 and 152, and the width of the first and

second reservoirs

1510 and 1520 are small enough to exert capillary forces on the liquid medium to perform a reservoir function. The width of the first reservoir 1510 is smaller than that of the second reservoir 1520, so that the capillary force of the first reservoir 1510 is stronger, and the purpose of the arrangement is that the liquid flowing out from the air return tank 153 preferentially enters the first reservoir 1510, and after the first reservoir 1510 is filled with the liquid, the liquid is sucked into the second reservoir 1520 far away from the liquid storage cavity 141, that is, the liquid is not uniformly distributed on the whole gas-liquid balance element 150 at the beginning, so that the liquid leakage probability can be reduced.

In some embodiments, the thickness of the first fins 151, the second fins 152, and the width of the first reservoir 1510 is between 0.05 and 0.2mm, preferably 0.09 and 0.15mm, and the width of the second reservoir 1520 is about 0.17. The gas-liquid balancing element 150 may further include a narrow air return groove 153 and a wide surface tension separating groove 154 in some embodiments, and the air return groove 153 and the surface tension separating groove 154 are respectively disposed at two opposite sides of the gas-liquid balancing element 150, and preferably, at a position of 180 degrees. The width of the air return channel 153, which in some embodiments may be between 0.05 and 0.2mm, and preferably between 0.09 and 0.15mm, intersects the first reservoir 1510 and the second reservoir 1520, respectively, transversely to the first partition 157, the first fin 151, the second partition 158, and the majority of the second fin 152, in a direction parallel to the axis of the air-liquid balance member 150. The two fins 151 of the illustrated air-liquid balancing component 150 near the bottom are not cut off by the air-returning groove 153, and the two fins 151 function to catch the air-returning groove 153, so as to increase the resistance of the liquid flowing downward, and if the liquid is about to leak out, the liquid can only flow to the surface tension separating groove 154 through the second liquid storage tank 1520 and then leak out downward, and due to the surface tension of the second fins 152, the leakage is difficult, so as to reduce the probability of leakage.

The air return groove 153 extends from a portion of the second fin 152 near the lower end to the top of the gas-liquid balance member 150, and is communicated with the liquid storage chamber 141, so that the liquid in the liquid storage chamber 141 can flow to the first liquid storage tank 1510 and the second liquid storage tank 1520 in each layer through the air return groove 153. The surface tension partition groove 154, which in some embodiments is between 1 and 2mm, and preferably, it may be between 1.2 and 1.7mm, also intersects the second partition 158 and all of the first and

second fins

151 and 152 in a direction parallel to the axis of the gas-liquid balance member 150, and also intersects the corresponding first and

second reservoirs

1510 and 1520, to achieve a tension partition of the liquid in the first and

second reservoirs

1510 and 1520.

The third partition 159 is formed with a first air inlet groove 1590 on the same side as the air return groove 153, and the first air inlet groove 1590 communicates with the surface tension blocking groove 154 via a gap between the third partition 159 and the second fin 152. The fourth isolation portion 155 is provided with a second air inlet groove 1550 on the same side as the surface tension isolation groove 154, and the second air inlet groove 1550 is communicated through a gap between the third isolation portion 159 and the fourth isolation portion 155. The second air inlet 1550 is further connected to the air inlet 1430 of the liquid storage housing 140, such that the surface tension isolation slot 154 is further connected to the air inlet 1430 of the liquid storage housing 140, and further connected to the external environment through the window 1132 of the housing 110. Preferably, the air inlet 1430 is isolated from the mist passage of the atomizer 1 so that the air supply passage is isolated from the mist passage to prevent negative pressure formed in the mist passage from adversely affecting the air supply.

Referring to fig. 9 and 10 together, in some embodiments, atmospheric return air may enter the reservoirs 1510 from the surface tension separator tank 154 and may accumulate toward the return air tank 153 (as indicated by the arrows in fig. 9). When negative pressure is generated in the liquid storage chamber 141, return air is drawn from the return air tank 153, and the liquid in each layer of liquid storage tank 1510 is drawn from the surface tension separating tank 154 and slowly flows back into the liquid storage chamber 141 toward the return air tank 153 until the internal and external pressures are balanced. When the air pressure in the liquid storage chamber 141 is too high, the liquid can also gradually flow downward into the liquid storage tanks 1510 via the air return grooves 153 (as shown by arrows in fig. 10) to keep the air pressure in the liquid storage chamber 141 in an equilibrium state. Leakage of liquid through the atomizing assembly 130 is avoided. In some embodiments, pressure equalization may also be achieved by gas forcing the liquid in the reservoir 1510 back into the reservoir chamber 141 via the return gas tank 153.

Referring to fig. 11 and 12 together, in some embodiments, the central shaft 156 further includes a through groove 1562 communicating the first reservoir 1510 and the second reservoir 1520 with the central through hole 1560, so that the first reservoir 1510 and the second reservoir 1520 can exchange liquid with the liquid guiding member 160, that is, when the liquid in the liquid guiding member 160 is insufficient, the liquid stored in the first reservoir 1510 and the second reservoir 1520 can enter the liquid guiding member 160 through the through groove 1562 (as shown by an arrow in fig. 11) to maintain smooth supply of the liquid. Conversely, when the liquid in the liquid guiding element 160 is abundant and the liquid in the first reservoir 1510 and the second reservoir 1520 is insufficient, the liquid in the liquid guiding element 160 can enter the reservoir 1510 through the through groove 1562 (as shown by the arrow in fig. 12), so as to prevent the liquid leakage problem caused by the excessive liquid in the liquid guiding element 160, and achieve the balance of the liquid. The width of the through slots 1562 is 0.01-2mm in some embodiments.

The through slots 1562 may be provided in one or more, sections or sections, as desired, either straight along the central axis 156 (as shown in fig. 8) or curved. The two through slots 1562 of fig. 8 are symmetrically distributed about the central axis 156, with each through slot 1562 spanning both the first and

second fins

151, 152. The channel 1562 of fig. 8 may also be divided into two sections, one section spanning part of the first fin 151 and one section spanning part of the second fin 152.

An air outlet is arranged at one end of the mist channel 212 far away from the atomization unit B, and the air outlet can form a cigarette holder for a user to suck smoke. A blocking member may be disposed on the air outlet to block the air outlet when the atomizer 210 is not in use, thereby preventing impurities from entering the mist pipe 212. A space is provided between the mist path 212 and the side wall of the housing 210 to facilitate the flow of the liquid around the circumference of the mist path 212. The reservoir 211 may be located at the periphery of the mist channel 212.
