The airway tube 112 may in some embodiments include a pair of longitudinally extending sumps 114 and a connecting portion 1121. The pair of sumps 114 are formed on opposite sides of the inner surface of the air guide tube 112, respectively, and are located at the upper end of the connecting portion 1121. It can be used to collect the condensate of trachea internal wall face to make it can follow catch basin 114 backward flow to atomizing main part 12, reduce the probability that the condensate got into in the user's mouth, thereby can promote user's use and experience. The sump 114 may be a fine groove having a capillary force. The connection portion 1121 is a vertical conduit having a transverse dimension smaller than the main portion of the airway tube 112, and is used to connect the atomizing body 12.

A reservoir 115 is formed by a cavity portion between the housing 111 and the airway tube 112 which can be used to store a liquid aerosol-generating substrate.

The atomizing assembly 122 is elongate and is mounted on the atomizing base 121 and is operable to heat atomize the liquid aerosol-generating substrate. The liquid-retaining cotton 123, which may be polymeric cotton in some embodiments, is a hollow flat racetrack type, and is understood to be generally annular and mounted on the atomizing base 121, and is adapted to absorb and retain the liquid aerosol-generating substrate, preventing the atomizer 10 from leaking from the junction of the reservoir 11 and the atomizing body 12. The liquid locking cotton 124 is arranged above the liquid locking cotton 123, has the same shape as the liquid locking cotton 123, can be in a hollow flat runway shape, has the lower surface directly contacted with the liquid locking cotton 123 and pressed against two ends of the atomizing component 122, and has the upper surface attached to the lower end of the liquid storage cotton 13; which can be used to receive and draw liquid aerosol-generating substrate from the liquid cotton 13 for atomisation by the atomising assembly 122.

Base 1211 may in some embodiments be in the form of a flattened racetrack that fits into housing 111, including a major axis and a minor axis; the periphery of the liquid-locking cotton can be connected with the housing 111 in a sealing manner, which constitutes the main external structure of the atomizer 10, and the upper end of the liquid-locking cotton can be used for installing the atomizing assembly 122, specifically, the liquid-locking cotton 123 is attached to the top surface of the base 1211.

The base 1121 can also receive other components of the atomizing body 12, which in some embodiments are used to receive the atomizing mount 1212 and the liquid-lock wool 123. The lower end of the base 1211 is connected to the main body 20, and transmits an electric signal from the main body 20 to the atomizing main body 12. The lower end of the atomizing support 1212 is mounted on the base 1211 and is integrally formed with the base 1211, and is used for mounting the atomizing assembly 122; the upper end of the atomizing support 1212 is connected to the air guide cover 125, so that the aerosol generated by the atomizing assembly 122 mounted on the atomizing support 1212 can be conducted through the air guide cover 125. The liquid locking cotton 123 and the liquid locking cotton 124 can be respectively sleeved on the atomizing support 1212, and as can be understood, the positions of the liquid locking cotton 123 and the liquid locking cotton 124 can be limited by the way that the liquid locking cotton 123 and the liquid locking cotton 124 are sleeved on the atomizing support 1212, and the inner space of the atomizer 10 is saved, so that the atomizer 10 has a smaller size under the condition that the functions are completely the same, and the use experience of a user is improved.

The two electrode posts 1213 are mounted in the mounting hole 1218 and electrically connected to the host 20, which can be used to electrically connect the atomizer 10 and the host 20, so that the atomizing assembly 122 in the atomizer 10 can perform its function of electrically atomizing. The magnetic element 1214 is embedded in the embedding hole 1210, which can be used for magnetic connection between the atomizer 10 and the host 20.

Base 1211 also includes, in some embodiments, at least one air guide channel 1211a. The air guide grooves 1211a are formed by the outer side surface of the base 1211 being depressed inward, and are provided in pairs on the upper portion of the outer side surface in the longitudinal direction of the base 1211; one end of the air-guide groove 1211a is in communication with the air-guide hole 1217.

The atomizing frame 1212 may, in some embodiments, include two legs 1212a, and each of the two legs 1212a may be C-shaped in cross-section and disposed opposite the long axis of the base 1212. Each leg 1212a includes a notch (not numbered) therein, which in some embodiments may be U-shaped in configuration on the leg. The two ends of the atomizing assembly 122 are respectively mounted on the two legs 1212 a.

An air flow collecting cavity (not numbered) may be formed between the two legs 1212a in some embodiments, and may be in communication with the other end of the air guide 1211a. In some embodiments, the liquid-locking cotton 123, the housing 111, and the air-guiding groove 1211a cooperate to form a closed air-guiding channel.

A sump 1216, which in some embodiments is located at the top of the atomizing base 121 and extends downward, is located below the atomizing assembly 122, it being understood that the sump 1216 is also located below the gas flow collection chamber; may be used to receive excess liquid aerosol-generating substrate absorbed by the atomizing assembly 122. The air vents 1217 extend through the atomizing base 121, are located on the long axis of the base 1211, and are located outside one of the two legs 1212 a. The air guide micro-holes are formed and used for conducting air for the atomizer 10 and the main machine 20, so that the main machine 20 is activated to supply power for the atomizer 10.

In some embodiments, the air-guide channel connects the air-guide holes 1217 to the air-guide tube 112, which effectively prevents the liquid aerosol-generating substrate in the nebulizer 10 from flowing into the host 20, since the air-guide holes are not located directly below the air-guide tube 112. The air guide channel effectively avoids the occurrence of leakage condition, thereby improving the use experience of the user.

The mounting holes 1218 are two in number, symmetrically disposed in the middle of the bottom, and are used to mount the two electrode posts 1213. The two line passing holes 1219 are communicated with the mounting hole 1218, the atomizing assembly 122 can be electrically connected to the electrode stem 1213 through the line passing holes 1219, and the atomizing assembly 122 can be powered on to realize the atomizing function. The two embedding holes 1210 are symmetrically disposed at two ends of the bottom of the atomizing base 121, and are used for the magnetic member 1214 to be embedded therein.

The atomizing assembly 122 may include a wick 1221, a heater 1222, and a wick 1223 in some embodiments. The liquid guiding core 1221 is in a shape of a long cylinder and is erected on the atomizing support 1212, and specifically, two ends of the liquid guiding core 1221 are respectively installed in and extend out of the notch of the upper bag of each of the legs 1212 a. The two ends of the liquid guiding core 1221 extending out of the gap are lapped between the liquid locking cotton 123 and the liquid locking cotton 124, namely the top surface of the liquid locking cotton 123 and the top surface of the liquid locking cotton 124; may be used to adsorb a quantity of liquid aerosol-generating substrate. The heating wire 1222 is made of an electric heating wire, and is wound around the elongated cylindrical liquid guiding core 1221, and both ends of the heating wire 1222 are respectively inserted into and penetrate through the two wire passing holes 1219 of the atomizing base 121, and are electrically connected to the two electrode posts 1213. When the host 20 is energized, current is conducted through the electrode shaft 1213 and energizes the heater 1222; the heating wire 1222 is energized to generate heat, which causes the liquid aerosol-generating substrate on the wick 1221 around which it is wound to be atomized. The liquid-locking cotton 1223 is vertically positioned between the airflow collecting cavity and the atomizing assembly 122, and understandably, the liquid-locking cotton 1223 is installed between the liquid guide core 1221 and the top surface of the atomizing base 121; in the horizontal direction, a containing cavity 1212b is formed between the two legs 1212a, and the liquid locking cotton 1223 is contained in the containing cavity 1212 b; which may be used to prevent spillage of the wicking 1221 due to excess liquid aerosol-generating substrate being adsorbed thereon.

The scoop 125 may, in some embodiments, include a smaller upper opening 1252, a larger lower opening 1253 than the upper opening 1252, and at least one sump 1251. The upper port 1252 is connected to the air duct 112 of the liquid storage shell 11 and is hermetically and airtightly connected with the air duct 112; in use by a user, aerosol enters the airway tube 112 through the upper port 1252. The lower port 1253 is connected to the atomizing support 1212 of the atomizing base 121 and covers the atomizing assembly 122; further, a lower opening 1253 of the air guide cover 125 is covered above the heating wire 1222, and the aerosol generated by the atomizing assembly 122 during the electrification and atomization is conducted to the upper opening 1252 through the lower opening 1253.

Since the upper opening 1252 is smaller than the lower opening 1253, the aerosol contacts the inner wall of the air guide shroud 125 when passing from the lower opening 1253 to the upper opening 1252. When contacting the inner wall of the silica gel air guide groove 2231, the aerosol particles with a poor atomization degree and larger particles form a condensate liquid, which is collected on the inner wall of the air guide cover 125, and the aerosol particles with a good atomization degree and smaller particles can pass through the air guide cover 125 for the user to suck.

At least one sump 1251 opens longitudinally into the inner wall of scoop 125 and extends from upper port 1152 to lower port 1253. In some embodiments, the less atomized, larger aerosol particles can form condensate and flow down the sump 1251 onto the atomizing assembly 122, the liquid-lock wool 123, or the liquid-lock wool 124. It will be appreciated that the lower opening 1253 of the scoop 125 is generally rectangular in shape, the scoop 125 is divided into four walls, and the inner wall surface of each wall of the scoop 125 is provided with at least one sump 1251.

In some embodiments, the scoop 125 may further include a ring of protrusions on the inner wall surface of the upper end thereof for engaging the connection portion 1121 of the airway tube 112. The outer surface of the connection portion 1121 abuts against the protrusion, so that the air guide cover 125 and the air guide tube 112 can be stably connected, and a sealing effect is provided. Further, the sump 114 within the airway tube 112 may, in some embodiments, be in communication with at least one sump 1251 within the airway hood 125.
