It should be understood that the first liquid guiding hole 2112 and the second liquid guiding hole 2113 together form the above-mentioned lower liquid channel. The liquid discharging channel is communicated with the liquid storage bin 31, so that the liquid aerosol generating substrate in the liquid storage bin 31 flows to the heating element 231 along the liquid discharging channel for heating and atomizing.

In some embodiments, the first conductive piece 233 is disposed in the first conductive hole 2122 in an interference manner, and two ends of the first conductive piece protrude from the first conductive hole 2122 respectively for electrically connecting the heating element 231 with a power source.

When the air inlet pipeline 2121 is closed by the adjusting piece 24, equipment damage caused by liquid leakage of the atomizer 1 under the conditions of high-temperature environment or long-time placement and the like can be avoided, and the service life of the equipment is prolonged.

In some embodiments, the first position and the second position are respectively located on a longitudinal axis of the air intake pipe 2121, the adjusting member 24 is axially movably disposed inside the air intake pipe 2121, and includes a base 241, a cylindrical sidewall 242, a sealing portion 243 and a limiting portion 244, wherein the base 241 is in a flat column shape, the cross section of the base 241 is circular, and the cylindrical sidewall 242 stands on an upper end surface of the base 241. The seal portion 243 is annular, is also located on the upper end surface of the base 241, and is provided around the lower end of the outer wall surface of the cylindrical side wall 242. Specifically, the diameter of the base 241 is matched with the diameter of the second sidewall in the air intake pipe 2121, the diameter of the sealing portion 243 is matched with the diameter of the first sidewall, and the sealing portion can be in interference fit connection with the first receiving groove to ensure sealing, and the diameter of the cylindrical sidewall 242 is smaller than the diameter of the first sidewall.

In some embodiments, the cylindrical sidewall 242 and the base 241 define a liquid storage chamber 246 therebetween, and the liquid storage chamber 246 is in liquid-guiding communication with the atomizing chamber 216 for collecting and storing condensate, and prevents condensate inside the first collecting tank 2132 and the second collecting tank 2142 from flowing to the lower base body to be oozed out after being saturated, thereby facilitating cleaning.

In some embodiments, the maximum radial dimension of the head 2441 is greater than the diameter of the limiting hole 2124, so as to limit the movement of the adjusting member 24, and limit the movement of the adjusting member only up and down along the axial direction of the atomizing base 21, but cannot be separated from the atomizing base 21.

In some embodiments, the adjusting member 24 is further provided with a control portion 245, and the control portion 245 is axially erected on the lower end surface of the base 241, for a user to control the position of the adjusting member 24, so as to achieve the purpose of switching on and off the atomizer 1.

In a specific use process, as shown in fig. 9 and 10, the atomizer 1 is in a closed state, and at this time, the sealing portion 243 is clamped inside the first sidewall and is in interference fit with the first sidewall, so as to achieve a sealed state, and the air inlet channel 42 is closed, so that the atomizer 1 cannot be used, and misuse of children can be avoided. It should be understood that, at this time, since the sealing portion 243 is in interference fit connection with the first sidewall, when the atomizer 1 is in the closed state, the adjusting member 24 is fixed in the above state and does not move down to the open state due to its own weight.

When the atomizer 1 needs to be started, only the control portion 245 needs to be pulled downward to enable the adjusting member 24 to move downward relative to the atomization seat 21 as a whole, as shown in fig. 11 and 12, the sealing portion 243 moves from a state of interference fit with the first side wall to the position of the air inlet pipe corresponding to the second side wall, at this time, the head 2441 is clamped on the upper end face of the limiting hole 2124, the adjusting member 24 moves downward to the limiting position, the air inlet channel 42 is opened, the air guide channel 40 is opened, and at this time, the atomizer 1 is in a usable state.

In some embodiments, the adjustment member 24 is also capable of moving back and forth about the longitudinal axis of the intake conduit 2121 in a third angular position and the second angular position. As the adjustment member 24 is rotated from the second angular position to the third angular position, the opening of the intake conduit 2121 is gradually increased (i.e., the intake passage 42 is gradually increased). The opening of the intake conduit 2121 gradually decreases (i.e., the intake passage 42 gradually decreases) as the adjuster 24 gradually rotates from the third angular position toward the second angular position.

Specifically, the adjusting member 24 includes a base 241 and a cylindrical side wall 242, wherein the base 241 is in a flat column shape, the cross section of the base is in a rectangular arrangement, two short sides of the cross section are arc-shaped, and the arc-shaped shape is adapted to the wall shape of the second side wall.

When the atomizer 1 needs to be used, only the control groove 2412 is required to be rotated to drive the adjusting member 24 to rotate, so that the two air guide grooves 2421 are respectively located at the positions corresponding to the two air inlet grooves 2126 gradually, and as shown in fig. 28 and 29, the air inlet channel 42 is opened, and the atomizer 1 is in an opened state. As the rotation amplitude increases, the area of the air guide groove 2421 corresponding to the air intake groove 2126 becomes larger, that is, the air intake passage 42 becomes larger, and the air flow increases.

The design of the two structures of the adjusting piece 24 and the air inlet pipeline 2121 can enable the atomizer 1 to be opened and closed at any time, so that misuse of children can be avoided, the rotating amplitude of the adjusting piece 24 can be controlled through the control groove 2412, the proportion of the two air guide grooves 2421 and the two air inlet grooves 2126 at the relative positions can be controlled, the size of the air flow channel can be controlled, the purpose of controlling the size of the air flow can be achieved, and user definition of atomized air flow can be achieved.
