In some embodiments, suitable materials for the heating element 142 include nickel, iron, stainless steel, nickel-iron alloy, nickel-chromium alloy, iron-chromium-aluminum alloy, or metallic titanium.

As shown in fig. 2, 4 and 5, the power module 20 includes a longitudinally extending battery cell 21 and a sealing member 22 disposed opposite to the battery cell 21, the sealing member 22 includes a first surface 221 and a second surface 222 disposed opposite to each other, and a first receiving chamber 223 extending between the first surface 221 and the second surface 222, the first surface 221 faces the battery cell 21, an abutment boss 224 abutting the battery cell 21 extends from the first surface 221, an extension wall 225 extends longitudinally on the abutment boss 224 in a direction away from the first receiving chamber 223, the extension wall 224 and the abutment boss 224 define a second receiving chamber 226, at least a portion of the battery cell 21 is received in the second receiving chamber 226, and when the battery cell 21 is received in the second receiving chamber 226, a side surface of the battery cell 21 elastically abuts an inner wall of the second receiving chamber 226 to form a seal, that is elastically abutting the extension wall 224, and a bottom end of the battery cell 21 maintains a first gap 227 with the first surface 221.

The first accommodating chamber 223 has a first opening 2231 and a second opening 2232 that are opposite to each other, a first gap 227 is kept between the bottom end of the battery cell 21 and the first opening 2231, and the microphone 23 is accommodated in the first accommodating chamber 223 through the first opening 2231, and the microphone 23 is used as an airflow sensing element for sensing airflow generated during suction of a user, so as to trigger the electronic atomization device 100 to start. Meanwhile, various functional circuits such as output power management, charge management, status indication and protection circuits can be integrated on the microphone 23, so that the microphone 23 can be used as a controller of the electronic atomization device 100, the electric core 21 and the heating element 142 are electrically connected with the microphone 23, and when a user sucks, the microphone 21 senses suction air flow and controls the electric core 21 to provide proper electric power for the heating element 142, and the heating element 142 can heat the liquid matrix to generate aerosol.

The bottom wall of the power supply assembly 20 is formed with an air inlet hole 210 for external air to enter the electronic atomizing device 100, the sealing member 22 maintains a second gap 228 with the bottom wall of the housing of the power supply assembly 20, the sealing member 22 is also formed with an air vent 229 communicating the first gap 227 with the second gap 228, the upper surface of the microphone 23 is exposed to the first gap 227 through a first opening 2231, the lower surface of the microphone 23 is exposed to the second gap 228 through a second opening 2232, and the air vent 229 can be used as an air flow inlet for external air to flow into the sealing member 22.

When the user draws in, external air enters the second gap 228 through the air inlet hole 210, then enters the first gap 227 through the air vent 229, then enters the gap 220 between the battery cell 21 and the housing of the power supply assembly 20, enters the air duct 12, and carries the aerosol in the air duct 12 to the air outlet hole 11, as shown by the arrow route R in fig. 5. Since the upper surface of the microphone 23 is exposed to the first gap 227 and the lower surface of the microphone 23 is exposed to the second gap 228, a pressure difference is generated due to the difference in pressure applied to the upper surface and the lower surface of the microphone 23 along with the flow of the external air, and the user can be judged to be sucking by detecting the pressure difference of the microphone 23.

As shown in fig. 4, the abutment boss 224 is formed with a notch, which is a first gap 227, and one end of the notch is connected as an air flow outlet of the sealing member 22 to the gap 220 between the battery cell 21 and the housing of the power supply unit 20, so that the first gap 227 is connected to the air flow inlet and the air flow outlet, and the air flow inlet and the air flow outlet are disposed at both sides of the microphone 23, so that the microphone 23 is triggered when the air flows along the first gap 227. The side surface of the battery core 21 is elastically abutted against the inner wall of the second accommodating chamber 226 to form a seal, so that after the external air enters the sealing member 22, the external air cannot be split in other directions and can only flow into the gap 220 along the first gap 227 to escape from the sealing member 22, and therefore, the flow rate of the air flow can be increased, and the microphone 23 can more sensitively detect the sucking action of the user as the flow rate of the air flow is increased.

In some embodiments, as shown in fig. 4, the notch is away from the first accommodating chamber 223, so that the microphone 23 can be completely exposed through the first opening 2231, so that the external air has a larger contact area with the upper surface of the microphone 23, which is advantageous for improving the triggering sensitivity of the microphone 23. And, in some embodiments, the vent 229 is longitudinally extending, the longitudinally extending vent 229 may shorten the distance of the external air flow to the first gap 227, thereby enabling the microphone 23 to sense the aspirated air flow in a timely manner for rapid triggering of the actuation of the electronic atomization device 100.

And, in some embodiments, as shown in fig. 5, since the sealing member 22 has flexibility, in order to avoid that when the vent hole 229 is provided on the sealing member 22, the size of the aperture of the vent hole 229 is inconsistent due to the influence of tolerance, so as to influence the air flow through the vent hole 2209, the vent hole 229 may be further provided with a rigid air guide pipe 2291, and the rigid air guide pipe 2291 may improve the uniformity of the aperture of the vent hole 229.

Further in some embodiments, as shown in fig. 4, the first gap 227 includes a first portion 2271 and a second portion 2272 in communication with the first portion 2271, the vent 229 is in communication with the first portion 2271, the first receiving chamber 223 is located in the second portion 2272, and the lateral width D1 of the first portion 2271 is smaller than the lateral width D2 of the second portion 2272, so that when outside air flows into the first portion 2271 through the vent 229, the outside air can quickly flow into the second portion 2272 due to the smaller lateral width of the first portion 2271, which is also advantageous for improving the sensitivity of the microphone 23. And in some embodiments, as shown in fig. 6, the longitudinal depth d1 of the first portion 2271 is greater than the longitudinal depth d2 of the second portion 2272, and an arc surface 2273 for guiding the air flow is connected between the first portion 2271 and the second portion 2272, where the arc surface 2273 can guide the external air to smoothly flow from the first portion 2271 to the second portion 2272, which is also advantageous for improving the triggering sensitivity of the microphone 23.

In some embodiments, as shown in fig. 5, the battery cell 21 is surrounded by a cylindrical body 24, the cylindrical body 24 is supported on the abutment boss 224, and the cylindrical body 24 is open at both ends and is hollow, so that at least a portion of the battery cell 21 is accommodated in the cylindrical body 24. The extension wall 224 extends between the cell 21 and the cylindrical body 24 so that the extension wall 224 is sandwiched between the cell 21 and the cylindrical body 24, and the extension wall 224 is elastically abutted against the side surface of the cell 21 to form a seal.

In some embodiments, as shown in fig. 5, a spacer 25 is further disposed in the power module 20, where the spacer 25 is supported on the abutment boss 224, so that when the battery cell 21 is accommodated in the second accommodating chamber 226, the bottom end of the battery cell 21 abuts against the spacer 25, so that the spacer 25 isolates the battery cell 21 and the microphone 23 from each other, and a short circuit of the battery cell 21 caused by contact between the tab of the battery cell 21 and the welding spot on the microphone 23 is avoided. . In some embodiments, at least a portion of the spacer 25 is rigid, for example, the spacer 25 may be made of a PC material with higher rigidity, and the rigid spacer 25 is not easy to deform, so that when the tab welding point at the bottom end of the battery cell 21 is too high, deformation of the spacer 25 is not caused, and the deformation of the spacer 25 is avoided, and the portion of the spacer 25 extends into the first gap 227 to block the flow of the air flow, so as to avoid affecting the sensitivity of the microphone 23 to the suction air flow.

It should be noted that, the atomizing assembly 10 and the power supply assembly 20 may be detachably connected or non-detachably connected, if the electronic atomizing assembly 100 is an integral type, the electronic atomizing assembly 300 may be discarded after the liquid substrate is consumed, and the electronic atomizing assembly 100 described in the above embodiment is an integral type, and the atomizing assembly 10 and the power supply assembly 20 are non-detachably connected.
