The hollow cylinder structure 21 and the inner wall of the liquid storage portion 20 define a first airflow channel 24 and a second airflow channel 25, aerosol generated by the atomization of the liquid matrix by the atomization element 30 can flow into the nozzle portion 10 through the first airflow channel 24 and the second airflow channel 25, and the aerosol can be sucked by the user through sucking on the air outlet hole 11 of the nozzle portion 10.

As shown in fig. 5 and 7, the atomizing element 30 includes a liquid guiding element 31 and a heating element 32 combined on the liquid guiding element 31, the liquid guiding element 31 may be made of a hard capillary structure such as porous ceramic, porous glass, etc., and has a large number of micro-pore structures inside, the liquid guiding element 31 may be in a block structure in embodiments, but not limited to, according to the use situation, it includes a liquid absorbing surface 311 and an atomizing surface 312 which are oppositely disposed along the length direction of the atomizer 100, that is, the upper surface and the lower surface of the block liquid guiding element 31 in fig. 7, the liquid absorbing surface 311 faces the liquid outlet 2111 and is further communicated with the liquid storage cavity 211 so as to absorb the liquid matrix, the heating element 32 is combined on the atomizing surface 312 so as to heat the atomized liquid matrix, and the liquid matrix can flow to the liquid absorbing surface 311 through the liquid outlet 2111 and flow to the atomizing surface 312 through the internal micro-pore structure of the liquid guiding element 31.

The heating element 32 is preferably formed on the atomizing surface 312 by mixing conductive raw material powder and printing aid into paste, and then sintering the paste after printing a proper pattern, so that all or most of the surface of the heating element is tightly combined with the atomizing surface 312, and the heating element has the effects of high atomizing efficiency, less heat loss, dry burning prevention or great reduction of dry burning, etc. In some embodiments, the heating element 32 may take various other forms, for example, the heating element 32 may be a sheet-shaped heating element with a specific pattern combined on the atomizing surface 312, or other forms such as a heating net, a disk-shaped heating element formed by a heating wire spiral, a heating film, etc.; in some examples, the particular pattern may be a serpentine shape. In some embodiments, suitable materials for the heating element 32 include nickel, iron, stainless steel, nickel-iron alloy, nickel-chromium alloy, iron-chromium-aluminum alloy, or metallic titanium. Thus, when the liquid matrix is transferred to the atomizing surface 312, the heating element 32 of the atomizing surface 312 heats and atomizes the liquid matrix, and the aerosol generated after atomization is released from the atomizing surface 312.

As shown in fig. 3, 5 and 6, the hollow cylinder structure 21 includes a side wall 2112 and a bottom wall 2113, the side wall 2112 and the bottom wall 2113 enclose to form a liquid storage cavity 211, and a liquid outlet 2111 is formed on the bottom wall 2113. Extending from the bottom wall 2113 in a direction away from the liquid storage chamber 211 is an extension wall 2114, the extension wall 2114 and the bottom wall 2113 defining a first receiving chamber 212, the atomizing element 30 being received in the first receiving chamber 212. In order to avoid leakage of the liquid matrix through the assembly gap between the atomizing element 30 and the inner wall of the first accommodating chamber 212, a second sealing member 50 is disposed between the atomizing element 30 and the first accommodating chamber 212, the second sealing member 50 is formed with a second accommodating chamber 51, the atomizing element 50 is tightly fitted in the second accommodating chamber 51, and the second sealing member 50 may be a soft rubber member such as silica gel or rubber, so that the second sealing member 50 may be elastically abutted between the atomizing element 30 and the inner wall of the first accommodating chamber 212, and further the second sealing member 50 provides sealing between the atomizing element 30 and the inner wall of the first accommodating chamber 212. It will be readily appreciated that the second seal 50 is also formed with a through-hole 52 through which the liquid matrix flows, the through-hole 52 being in communication with the liquid outlet 2111, the liquid matrix flowing through the liquid outlet 2111 and through-hole 52 to the atomizing element 30.

As shown in fig. 5, the air inlet 61 and the electrode hole of the atomizer 100 are provided on the bracket 60, the conductive electrode 62 is inserted in the electrode hole, one end of the conductive electrode 62 is electrically connected with the main board through an electrical connector, and the other end extends to the atomizing surface 312 of the liquid guiding element 31 so as to be electrically connected with the heating element 32 of the atomizing surface 312, so that the electric core 70 can provide the electric energy required for heating the heating element 32 through the conductive electrode 62. It will be appreciated that the conductive electrode 62 comprises two electrode posts which serve as positive and negative poles for conducting current, the ends of the conductive electrode 62 abutting against the atomizing element 30 to support it for positioning in the first housing chamber 212 described above.

The support 60 supports a first sealing member 40, the first sealing member 40 may be a soft rubber member such as silica gel or rubber, the first sealing member 40 is in interference fit with the inner wall of the liquid storage portion 20 so as to seal the distal end 23 of the liquid storage portion 20, the first sealing member 40 is disposed opposite to the atomizing element 30 and defines an atomizing chamber 313, and aerosol generated by heating the atomized liquid matrix by the atomizing element 30 is released.

When the user draws with the atomizer 100, the external cold air enters the atomizing chamber 313 and mixes with the high temperature aerosol in the atomizing chamber 313, the high temperature aerosol is condensed to form condensed droplets falling when meeting the external cold air, and the seal formed by the first seal member 40 prevents the dropped condensed liquid from leaking from the distal end 23 of the liquid storage portion 20 to the power supply assembly 200.

The air inlet 61 provides an air flow inlet for external air into the atomizer 100, the air vent 41 is formed on the first sealing member 40, the air vent 41 is communicated with the air inlet 61 and the atomization chamber 313, so that when a user sucks, negative pressure is generated inside the atomization chamber 313, the external air is caused to flow into the atomization chamber 313 through the air inlet 61 and the air vent 41, then aerosol in the atomization chamber 313 is carried to flow into the first air flow channel 24 and the second air flow channel 25, then flows into the nozzle part 10 through the first air flow channel 24 and the second air flow channel 25, finally, the air escapes from the atomizer 100 through the air outlet 11 of the nozzle part 10 for the user to suck, and a complete air flow path of the atomizer 100 is formed, as shown by an arrow route R in fig. 5.

As shown in fig. 3, the inner wall of the first accommodating chamber 212 is formed with a groove 2115, when the second sealing member 50 is assembled between the atomizing element 30 and the inner wall of the first accommodating chamber 212, the second sealing member 50 and the groove 2115 define an air channel, and the air channel is communicated with the external air and the liquid outlet 2111, so that the external air can be guided to enter the liquid storage cavity 211 through the liquid outlet 2111 to supplement the air into the liquid storage cavity 211, thereby avoiding the negative pressure generated in the liquid storage cavity 211 along with the consumption of the liquid matrix, and further the liquid matrix cannot smoothly flow to the atomizing element 30 under the action of the negative pressure, and the dry burning of the atomizing element 30 is easily caused.

As shown in fig. 5, the liquid storage portion 20 is further provided with a heat conducting element 90 extending longitudinally, the heat conducting element 90 contacts with the liquid guiding element 31, when the heating element 32 works, heat generated by the heating element 32 is transferred to the liquid guiding element 31, and the heat conducting element 90 contacts with the liquid guiding element 31 so as to receive heat on the liquid guiding element 31 and conduct the heat further along the extending direction of the heat conducting element 90.

Specifically, as shown in fig. 5 and 8, the heat conducting member 90 is capable of sucking the liquid surface 311 and longitudinally extending into the liquid storage cavity 211 through the liquid outlet 2111, so that the heat conducting member 90 separates the liquid sucking surface 311 into the first liquid sucking region 3111 and the second liquid sucking region 3112, that is, separates the first liquid sucking region 3111 and the second liquid sucking region 3112 from each other, and after the liquid substrate flows out of the liquid storage cavity 211, the liquid substrate is absorbed by the liquid sucking surface 311 in the first liquid sucking region 3111 and the second liquid sucking region 3112, respectively.

Thus, in the above manner, when the outside air is introduced into the air passage, it escapes from the air passage in the form of bubbles, and the bubbles that are flushed out of the air passage collide with the heat conductive member 90 and are guided into the liquid storage chamber 211 along the heat conductive member 90 in a direction away from the liquid suction surface 311, and the bubbles cannot flow from the first liquid suction region 3111 to the second liquid suction region 3112 or from the second liquid suction region 3112 to the first liquid suction region 3111. That is, when air bubbles accumulate in the first suction region 3111 to hinder the first suction region 3111 from sucking up the liquid substrate, the liquid substrate may be sucked up in the second suction region 3112, and thus the liquid supply on the atomizing element 30 may be continuously maintained through the second suction region 3112; when the accumulation of bubbles in the second suction region 3112 prevents the second suction region 3112 from sucking up the liquid medium, the liquid medium may be sucked up in the first suction region 3111, and the supply of liquid to the atomizing element 30 may be continued.

In addition, since the heat conducting element 90 extends into the liquid storage cavity 211, when the liquid matrix stored in the liquid storage cavity 211 is more viscous, the heat conducting element 90 can heat and dilute the liquid matrix above the liquid suction surface 311, so that the blocking of the viscous liquid matrix to bubbles can be effectively relieved, the bubbles can smoothly float up into the liquid storage cavity 211, and air can be timely supplemented into the liquid storage cavity 211.

In some embodiments, as shown in fig. 8, the heat conducting element 90 passes through the central region of the liquid outlet 2111, so that the first liquid absorbing zone 3111 and the second liquid absorbing zone 3112 have substantially the same area, and when either one of the first liquid absorbing zone 3111 and the second liquid absorbing zone 3112 is blocked by the accumulated bubbles and cannot absorb the liquid matrix smoothly, the liquid absorbing area of the other liquid absorbing zone can maintain the liquid amount supplied to the atomizing element 30, so that dry burning of the atomizing element 20 due to poor liquid supply is avoided.

In some embodiments, as shown in fig. 9, the liquid outlet 2111 has a first wall 2111a and a second wall 2111b opposite to each other, the heat conductive element 90 includes a first portion 91 extending in the liquid storage chamber 211, and a second portion 92 located outside the liquid storage chamber 211, the second portion 92 being held between the first wall 2111a and the second wall 2111b such that the first wall 2111a and the second wall 2111b hold the heat conductive element 90 therebetween, and the second portion 92 separates the liquid suction surface 311 into a first liquid suction region 3111 and a second liquid suction region 3112.

Further in some embodiments, as shown in fig. 10, the second portion 92 is provided with a first clamping arm 921 and an opposite second clamping arm 922 extending toward the liquid suction surface 311, the first clamping arm 921 and the second clamping arm 922 form a clamping space 923, and at the same time, a connecting arm 2111c is connected between the first wall 2111a and the second wall 2111b, and when the second portion 92 is clamped between the first wall 2111a and the second wall 2111b, the first clamping arm 921 and the second clamping arm 922 clamp on the connecting arm 2111c, so that the heat conductive element 90 can be positioned by providing the connecting arm 2111c so that the heat conductive element 90 is precisely installed at a preset position. For example, by disposing the connection arm 2111c at the intermediate position of the liquid outlet 2111, it is possible to secure the heat conductive member 90 passing through the central region of the liquid outlet 2111.

Further, as shown in fig. 11, the first holding arm 921 and the second holding arm 922 have different extension lengths, the first holding arm 921 and the liquid suction surface 311 are kept with a gap 9211, the second holding arm 922 abuts against the liquid suction surface 311, so that the second holding arm 922 separates the liquid suction surface 311 into a first liquid suction region 3111 and a second liquid suction region 3112, and the first holding arm 921 and the liquid suction surface 311 are kept with a gap 9211 to form an avoidance region to avoid the liquid suction area of the liquid suction surface 311 from being reduced.

In some embodiments, as shown in fig. 12, the first portion 91 abuts against the inner wall of the liquid storage cavity 211, so that the liquid storage cavity 211 is divided into a first liquid storage area 211a and a second liquid storage area 211b, and accordingly, the first liquid storage area 211a is communicated with the first liquid suction area 3111, and the second liquid storage area 211b is communicated with the second liquid suction area 3112, so that bubbles generated on two sides are isolated from each other, and it is beneficial for the bubbles to float up into the liquid storage cavity 211 smoothly.

Further in some embodiments, as shown in fig. 13, the first portion 91 has a longitudinally extending gap 911 configured to prevent the passage of air bubbles while directing the passage of the liquid matrix such that the liquid matrix is free to flow between the first and second liquid storage regions 211a, 211b through the gap 911.

In some embodiments, the first portion 91 may also replace the notch 911 by providing a plurality of through holes, for example, a plurality of through holes may be sequentially arranged along the longitudinal direction, or a plurality of through holes may be arranged side by side, where the shape of the through holes is not limited, and only needs to enable the liquid substrate to freely flow between the first liquid storage area 211a and the second liquid storage area 211 b.

In some embodiments, the heat conducting element 90 is made of stainless steel, on the one hand, the stainless steel has good heat absorption and heat preservation properties, can quickly absorb heat on the liquid conducting element 31, can maintain the heat for a long time, and can not quickly dissipate the heat, so that the heating dilution of the liquid matrix is beneficial; on the other hand, since the heat conducting element 90 extends into the liquid storage cavity 211, the heat conducting element 90 made of stainless steel material is not easy to react with the liquid matrix, so that the probability of quality change of the liquid matrix can be reduced, and the safety of the user after sucking is further effectively improved.

It should be noted that, the connection between the atomizer 100 and the power supply assembly 200 may be a detachable connection or a non-detachable connection, if the connection is a non-detachable connection, the electronic atomization device 300 is integrated, after the liquid substrate in the liquid storage cavity 211 is consumed, the electronic atomization device 300 may be discarded, for example, the electronic atomization device 300 described in the above embodiment is integrated, and the atomizer 100 and the power supply assembly 200 are non-detachable connected.

In some embodiments, the atomizer 100 and the power supply assembly 200 are detachably connected, for example, the atomizer 100 and the power supply assembly 200 may be connected by a detachable connection such as a snap connection, a magnetic connection, etc., so that the electronic atomization device 300 is split. When the liquid matrix in the liquid storage chamber 211 is consumed, the atomizer 100 can be replaced with a new one, and the power supply assembly 200 can be reused. As shown in fig. 14, the power supply assembly 200 includes a receiving cavity 210 provided at one end in a length direction for receiving and accommodating at least a portion of the atomizer 100, and an electrical contact 220 at least partially exposed at a surface of the receiving cavity 210 for forming an electrical connection with the conductive electrode 62 of the atomizer 100 to thereby power the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated within the power supply assembly 200.

A sealing member 230 is provided in the power supply assembly 200, and at least a portion of the inner space of the power supply assembly 200 is partitioned by the sealing member 230 to form the above receiving chamber 210. In the preferred embodiment shown in fig. 14, the seal 230 is configured to extend along the cross-section of the power supply assembly 200 and is preferably made of a flexible material such as silicone to prevent the liquid matrix that seeps from the atomizer 100 to the receiving chamber 210 from flowing to the controller 240, sensor 250, etc. within the power supply assembly 200.

In the preferred implementation shown in fig. 14, the power assembly 200 further includes a battery cell 260 for supplying power that is longitudinally directed away from the other end of the receiving cavity 210; and a controller 240 disposed between the battery cell 260 and the receiving cavity 210, the controller 240 being operable to direct electrical current between the battery cell 260 and the electrical contact 220.
