With continued reference to fig. 4, the bottom wall 14a is provided with a flow guide 14c, and the relationship between the air inlet 1411 and the flow guide 14c is described from another angle. Specifically, the base 14 is formed with an air intake passage 141 and an airflow chamber 142. The airflow chamber 142 is located at the bottom of the nebulization chamber 120. The intake passage 141 is provided around the airflow chamber 142. The air inlet channel 141 is communicated with the atomization cavity 120 through the airflow cavity 142; specifically, the airflow chamber 142 has an airflow port 1421 provided in a chamber wall thereof, and the air intake passage 141 communicates with the airflow chamber 142 through the airflow port 1421. The port of the intake passage 141 facing away from the airflow chamber 142 is defined as an intake port 1411. External air enters the air inlet channel 141 through the air inlet 1411, flows into the air flow cavity 142 through the air flow port 1421, then enters the atomization cavity 120 through the air flow cavity 142, and carries the atomized aerosol in the atomization cavity 120 to flow out from the connecting pipe 126 and the mist outlet channel 111.

In one embodiment, two air inlet channels 141 are formed on the base 14, and the two air inlet channels 141 respectively encircle two sides of the airflow cavity 142. By providing two air intake passages 141, the amount of intake air is increased, which is advantageous in providing a better atomizing taste. The second side and the third side of the flow guiding member 14c are spaced from the side wall 14b, so that a part of the gas flowing in from the gas inlet 1411 flows toward the atomizing chamber 120 along the second side of the flow guiding member 14c, and a part flows toward the atomizing chamber 120 along the third side of the flow guiding member 14c, thereby forming two gas inlet channels 141. Note that the intake passage 141 in the present application is not limited to two, and is specifically designed as needed.

Alternatively, the intake ports 1411 of the two intake passages 141 are the same; that is, the air inlet 1411 is provided on the wall of the air inlet 141, and the external air is branched into the two air inlet 141 after entering from the air inlet 1411, so that the processing difficulty can be reduced.

Alternatively, the intake ports 1411 of the two intake passages 141 are independent of each other; that is, two intake ports 1411 are provided in the passage walls of the intake passage 141, and the two intake ports 1411 are provided in one-to-one correspondence with the two intake passages 141. It will be appreciated that the projected area of the baffle on the side wall 14b completely covers both inlets 1411.

Alternatively, the two air intake passages 141 communicate with the same air flow port 1421; that is, the air flow chamber 142 has one air flow port 1421 formed in the wall thereof, and the two air inlet passages 141 are both connected to the air flow port 1421, so that the processing difficulty can be reduced.

Optionally, two air inlets 1421 are provided on the wall of the air cavity 142, and the two air inlet channels 141 are respectively in one-to-one correspondence with the two air inlets 1421.

Alternatively, the two air intake passages 141 are symmetrically disposed along the airflow chamber 142.

Referring to fig. 5 and 6, fig. 5 is a schematic structural view of the base of the atomizer shown in fig. 2 from another perspective, and fig. 6 is a schematic structural view of the holder of the atomizing area shown in fig. 2.

The end of the bracket 13 facing the base 14 is provided with a clamping groove 132, the end face of the side wall of the first groove 142a is provided with a clamping column 146 (namely, the end face of the flow guiding piece 14c is provided with the clamping column 146), the clamping column 146 is arranged in the clamping groove 132, and after the bracket 13 is connected with the base 14, the first groove 142a and the atomization cavity 120 are aligned. The inner surface of the first groove 142a is provided with a supporting portion 147 (i.e. the side surface of the flow guiding member 14c, which faces away from the air inlet 1411, is provided with the supporting portion 147), and the end surface of the supporting portion 147, which is close to the bracket 13, is abutted against the bracket 13, so that the structural stability of the airflow cavity 142 is improved.

With continued reference to fig. 2, the end of the base 14 remote from the bracket 13 is formed with a blind hole 143, the blind hole 143 being in communication with the air intake passage 141; specifically, the air inlet 1411 is provided on a side wall of the blind hole 143, and the blind hole 143 communicates with the air inlet passage 141 through the air inlet 1411. The port of the blind hole 143 is in direct communication with the outside air. In other words, the sidewall 14b of the base 14 is provided with a blind hole 143, the blind hole 143 is opened facing away from the bracket 13, and the air inlet 1411 is provided on the sidewall of the blind hole 143.

The base 14 is further provided with a liquid injection hole 144, the liquid injection hole 144 extends to the surface of the support 13 away from the base 14, that is, the liquid injection hole 144 penetrates through the base 14 and the support 13 along the axial direction of the atomizer 1, and the liquid injection hole 144 is communicated with the liquid storage cavity 10. The filling port 144 is used to fill the reservoir 10 with aerosol-generating substrate. The filling hole 144 is embedded with a plug 145. When the atomizer 1 is used for atomization, the plug 145 seals the liquid injection hole 144 to avoid liquid leakage; the shortage of aerosol-generating substrate in the reservoir 10 opens the stopper 145 and injects aerosol-generating substrate into the reservoir 10 from the injection hole 144.

The end of support 13 that keeps away from base 14 is equipped with baffle 133, and baffle 133 encircles the circumference setting of atomizing subassembly 12, and baffle 133 and atomizing subassembly 12 surface interval set up, and baffle 133 shelters from the first hole structure on the downcomer 125 of atomizing subassembly 12, avoids the direct impact second liquid guide 124 of the pressure of the aerosol generation matrix in the liquid storage chamber 10, causes the weeping. Optionally, the baffle 133 is integrally formed with the bracket 13.

It should be noted that, the projection area of the guide member 14c on the side wall 14b covers at least part of the air inlet 1411, so that the liquid flowing back from the atomizing assembly 12 does not directly flow to the air inlet 1411, and the liquid needs to bypass to flow to the air inlet 1411, so that the amount of the liquid leaked to the outside of the atomizer is reduced, and the influence of the liquid leakage on the performance of the host is improved. Wherein the structure of the atomizing assembly 12 is not limited to the above-described structure, and is illustrated by way of example only; the same technical effect can be achieved by adopting the atomizing assembly with other structures, and the guide piece 14c and the air inlet 1411 are arranged as above.
