The heat generating component 22 may include a base 221, an atomizing core 222, and a heat generating seat component 223, wherein the atomizing core 222 is accommodated in a space formed between the base 221 and the heat generating seat component 223. The atomizing core 222 is in fluid-conducting communication with the reservoir and in air-conducting communication with the air outlet channel for heating and atomizing the liquid substrate drawn from the reservoir to generate the aerosol. An atomizing chamber is formed between the base 221 and the atomizing core 222 for mixing the aerosol with ambient air. The lower end surface of the base 221 may be further concavely formed with an air inlet hole 200. The lower end of the casing 21 may in some embodiments comprise an insertion portion 211 for insertion into the battery module 2, the insertion portion 211 having a cross section in the shape of a racetrack, the cross section of the insertion portion 211 having a major axis and a minor axis, and the outer wall surfaces of the wall portions of the insertion portion corresponding to the two ends of the major axis of the cross section of the insertion portion 211 are each provided with a downwardly extending guide groove 210 for guiding ambient air to the step 114 of the power module 1. The groove section of the guide groove 210 connected to the step 114 may be inclined to make the airflow more smooth. It is understood that the number of the guide grooves 210 may be one or more.

Referring to fig. 5 to 7 together, the power module 1 may include a flat pillar shaped bracket 10, an airflow sensing member 20, a control board 30, a battery 40, an electrode post 50, a magnetic attraction member 60, and a housing 70. The rack 10 is used for installing the airflow induction part 20, the battery 40, the electrode column 50 and the magnetic attraction part 60, and the control board 30 is connected with the rack 10 and shields the airflow induction part 20 from one side. The airflow sensing member 20 and the battery 40 are electrically connected to the control board 30, and when the airflow sensing member 20 detects a change in airflow or air pressure, a trigger signal is sent, and the control board 30 controls the battery 40 to supply power to the atomizer 2, wherein the airflow sensing member 20 may be a microphone or other device that detects a change in airflow pressure or a change in flow rate. The electrode column 50 is electrically connected to the control board 30 for externally connecting the atomizer 2 to supply power to the atomizer 2. This magnetism is inhaled subassembly 60 and is cooperated with the magnetism structure of inhaling on the atomizer 2 to make power supply module 1 can dismantle with atomizer 2 and be connected through the effect of magnetism. The housing 70 forms a receiving cavity, so that the airflow sensing member 20, the control board 30, the battery 40, the pair of electrode posts 50 and the pair of magnetic attraction members 60 are inserted into the receiving cavity together with the bracket 10.

As further shown in fig. 6, the bracket 10 may include an upper end wall 11 having a racetrack shape, a partition wall 12 spaced parallel to the upper end wall 11, and a blocking wall 13 connected between the upper end wall 11 and the partition wall 12, wherein a mounting chamber 110 is provided between the upper end wall 11 and the partition wall 12, and the mounting chamber 110 has an opening opposite to the blocking wall 13 for mounting the airflow sensor 20.

The upper end wall 11 may include, in some embodiments, a reservoir 111, an intake column 112 disposed inside the reservoir 111, a cylindrical side wall 113 disposed at a periphery of the reservoir 111, an elliptical step 114 disposed at a periphery of the side wall 113, a pair of first receiving grooves 115, and a pair of second receiving grooves 116. The air inlet hole 200 on the atomizer 2 is approximately opposite to the center of the liquid storage tank 111, and the liquid storage tank 111 is mainly used for containing leaked liquid or condensate leaked from the air inlet hole 200, so that the leaked liquid or the condensate is prevented from easily flowing to electronic components such as the airflow sensing part 20, the control panel 30 and the battery 40, and the probability of generating electrical faults is reduced. The intake column 112 communicates with the installation cavity 110 to communicate the airflow sensor 20 with the reservoir 111. The side wall 113 is fitted to the bottom surface of the atomizer 2 so that the bottom surface of the atomizer 2 covers the upper end surface of the holder 10. The step 114 is in communication with the outside air. The pair of first receiving grooves 115 is used to mount the two electrode posts 50, respectively. The pair of second receiving grooves 116 are used for respectively mounting the two magnetic attracting elements 60.

An air hole 1120 is arranged at one end of the air inlet column 112 far away from the bottom wall of the liquid storage tank 111. The position of the air inlet column 112 is offset from the position of the air inlet hole 200 of the atomizer 2 to prevent leakage or condensation from easily falling into the air hole 1120 of the air inlet column 112. The outside air flow passes through the liquid storage tank 111 and is led to the air inlet hole 200 of the atomizer 2, and liquid such as water vapor and leakage carried by the air flow can be condensed on the end surface of the air inlet column 112, even the liquid on the end surface of the bracket 10 is guided to the air inlet column 14, so that the air hole 1120 has a higher risk of being blocked. It is understood that the air intake column 112 is disposed in the reservoir 111, that is, the air intake column 112 is connected to the bottom wall of the reservoir 111, and the air intake column 112 is disposed at a distance from the sidewall 113 of the reservoir 111; alternatively, in other embodiments, the air inlet column 112 may be partially or completely embedded in the sidewall 113 of the reservoir 111, so that it may be spaced a greater distance from the air inlet hole 200 of the atomizer 2, thereby significantly reducing the probability of leakage into the air hole 1120.

The sidewall 113 may be in a racetrack shape in some embodiments, and the cross section of the sidewall 113 has a long axis and a short axis, and it may include two sets of air blocking holes 1131, where the two sets of air blocking holes 1131 are disposed on the wall portions corresponding to the two ends of the short axis of the sidewall 113, and penetrate through the two wall portions of the sidewall 113 along the thickness direction, and have a relatively short distance from the air intake column 112, and bypass the electrode column 50 and the magnetic element 60, so that when the external air flows into the reservoir 111 through the air blocking holes 1131, the external air better passes through the air intake column 112 and enters the air hole 1120, so that the air hole 1120 can efficiently detect the air flow condition. In some embodiments, one set of gas holes 1131 in the wall of the sidewall 113 closer to the inlet column 112 includes two spaced gas holes 1131, and another set of gas holes 1131 in the other wall includes three spaced gas holes 1131. It is understood that the choke holes 1131 may be disposed at other positions on the sidewall 113, and the number of the choke holes 1131 may be set according to the requirement.

The step 114 may include four streamline-shaped flow guiding protrusions 1141 in some embodiments, and each flow guiding protrusion 1141 is provided with a plurality of liquid absorbing grooves 1142 having capillary force. The four flow guide protrusions 1141 are respectively arranged on two opposite sides of the two air blocking holes 1131 in pairs, so that the air passage is smooth, the generation of vortex is avoided, and the noise reduction effect is achieved. Specifically, when the airflow enters the step 114 from the guide groove 210 of the atomizer 2, the airflow first passes through the guide protrusion 1141 and then flows to the choke hole 1131, and the guide protrusion 1141 guides the airflow well, so as to achieve the noise reduction effect. The liquid suction grooves 1142 are extended downward from the top surfaces of the four guide protrusions 1141, respectively, for sucking the condensate, thereby preventing the condensate from blocking the air blocking holes 1131.

In some embodiments, each of the guiding protrusions 1141 is disposed on the step 114 near the gas blocking hole 1131, and an end of the guiding protrusion 1141 away from the gas blocking hole 113 is near the guiding groove 210, and the guiding groove 210, the step 114, the guiding protrusion 1141 and the gas blocking hole 1131 are sequentially communicated to form an air inlet path. It will be appreciated that although the step 114 in some embodiments includes four guide protrusions 1141 disposed around the step 114 to correspond to the two guide slots 210 on the atomizer 2. It is understood that in other embodiments, the number of the guide protrusions 1141 may be less than or more than four.

The wall surface of the mounting cavity 110 is provided with an air guide groove 1101 communicated with the air hole 1120, and the air guide groove 1101 is arranged in a winding manner. The air guide grooves 1101 arranged in a winding manner can slow down the liquid entering from the air holes 1120 to flow to the airflow induction part 20, and is also beneficial to reducing the risk of damage of the airflow induction part 20 due to moisture.

The power module 1 further comprises a fixing member 80 in some embodiments, and the fixing member 80 is embedded in the mounting cavity 110. The fixing member 80 may include a through groove 81 and a baffle ring 82 in some embodiments, the through groove 81 is communicated with the air guide groove 1101, the through groove 81 is used for installing the airflow sensing member 20, and the baffle ring 82 is disposed on a side of the through groove 81 facing the installation cavity 110, and is convenient for assisting in installing the airflow sensing member 20 in the through groove 81.
