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 atomizing support 1212 is sleeved with the liquid locking cotton 123 and the liquid locking cotton 124, and the internal 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 atomizing frame 1212 may, in some embodiments, include two legs 1212a, each of the two legs 1212a may be C-shaped in cross-section and disposed opposite a 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-lock cotton 123, the housing 111, and the air-guide slot 1211a cooperate to form a closed air-guide channel.

A sump 1216, which in some embodiments is disposed at the top of the atomizing base 121 and extends downwardly, is located below the atomizing assembly 122, it being understood that the sump 1216 is also located below the air flow collection chamber; may be used to receive excess liquid aerosol-generating substrate absorbed by the atomizing assembly 122. The air vents 1217 penetrate 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. Which is formed by a plurality of gas guide micro-holes and can be used for conducting gas for the atomizer 10 and the main machine 20, thereby activating the main machine 20 to supply power for the atomizer 10.

In some embodiments, the air-guide channel connects the air-guide opening 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 because the air-guide opening is 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 number of the mounting holes 1218 is two, symmetrically opened in the middle of the bottom, for mounting the two electrode posts 1213. The two wire through holes 1219 are in communication with the mounting hole 1218, and the atomizing assembly 122 can be electrically connected to the electrode post 1213 through the wire through holes 1219, so that the atomizing assembly 122 can be electrically connected to achieve its atomizing function.

When the host 20 is energized, current is conducted through the electrode shaft 1213 and energizes the heater 1222; the heater 1222 is electrically energized to generate heat to atomize the liquid aerosol-generating substrate around the wick 1221. 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 wick 1221 due to excessive adsorption of the liquid aerosol-generating substrate thereon.

The scoop 125 in some embodiments can include a smaller upper opening 1252, a larger lower opening 1253 compared to the upper opening 1252, and at least one sump 1251.

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 the scoop 125 and extends from the upper opening 1152 to the lower opening 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 is understood that the lower opening 1253 of the air guide cover 125 is substantially rectangular in shape, the air guide cover 125 is divided into four walls, and the inner wall surface of each wall of the air guide cover 125 is provided with at least one liquid collecting groove 1251.

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 have a sealing effect. 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.
