As shown in fig. 3 and 6, the atomizing element 40 includes a liquid guiding element 41 and a heating element 42 coupled to the liquid guiding element 41, where the liquid guiding element 41 may be made of a hard capillary structure such as porous ceramic, porous glass, etc., and has a large number of micro-porous structures inside, and the liquid guiding element 41 may be, but is not limited to, a block structure in an embodiment, and includes a liquid absorbing surface 411 and an atomizing surface 412, which are oppositely disposed along the length direction of the atomizer 100 according to the use situation, that is, the upper and lower surfaces of the block-shaped liquid guiding element 41 in fig. 6, the liquid absorbing surface 411 faces the liquid outlet 2111 and is further communicated with the liquid storage cavity 211 so as to absorb the liquid matrix, and the heating element 42 is coupled to the atomizing surface 412 so as to heat the atomized liquid matrix, and the liquid matrix may flow to the liquid absorbing surface 411 through the liquid outlet 2111 and flow to the atomizing surface 412 through the internal micro-porous structure of the liquid guiding element 41.

The heating element 42 is preferably formed on the atomizing surface 412 by mixing conductive raw material powder and a printing aid into a 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 412, 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 42 may take various other forms, for example, the heating element 42 may be a sheet-shaped heating element with a specific pattern combined on the atomizing surface 412, 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 42 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 412, the heating element 42 of the atomizing surface 412 heats and atomizes the liquid matrix, and the aerosol generated after atomization is released from the atomizing surface 412.

As shown in fig. 3 and 5, 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 chamber 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 40 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 40 and the inner wall of the first accommodating chamber 212, a second sealing member 60 is disposed between the atomizing element 40 and the first accommodating chamber 212, the second sealing member 60 is formed with a second accommodating chamber 61, the atomizing element 40 is tightly fitted in the second accommodating chamber 61, and the second sealing member 60 may be a soft rubber member such as silica gel or rubber, so that the second sealing member 60 may be elastically abutted between the atomizing element 40 and the inner wall of the first accommodating chamber 212, and the second sealing member 60 provides sealing between the atomizing element 40 and the inner wall of the first accommodating chamber 212. It will be readily appreciated that the second seal 60 is also formed with a through-hole 62 through which the liquid matrix flows, the through-hole 62 being in communication with the liquid outlet 2111, the liquid matrix flowing through the liquid outlet 2111 and through-hole 62 to the atomizing element 40.

As shown in fig. 3, the bracket 30 is provided with an air inlet 31 and an electrode hole of the atomizer 100, a conductive electrode 32 is inserted in the electrode hole, one end of the conductive electrode 32 is electrically connected with the main board through an electrical connector, and the other end extends to the atomizing surface 412 of the liquid guiding element 41 so as to be electrically connected with the heating element 42 of the atomizing surface 412, so that the electric core 80 of the conductive electrode 32 can provide electric energy required for heating the heating element 42. It will be appreciated that the conductive electrode 32 comprises two electrode posts which serve as positive and negative poles for conducting current, the ends of the conductive electrode 32 abutting against the atomizing element 40 to support it for positioning in the first housing chamber 212.

The support 30 supports a first sealing member 50, the first sealing member 50 may be a soft rubber member such as silica gel or rubber, the first sealing member 50 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 50 is opposite to the atomizing element 40 and defines an atomizing chamber 413, and aerosol generated by heating the atomized liquid matrix by the atomizing element 40 is released.

When a user draws using the atomizer 100, external cold air enters the atomizing chamber 413 and mixes with the hot aerosol in the atomizing chamber 413, the hot aerosol is condensed to form condensed droplets when meeting the external cold air, and the first seal 50 forms a seal to prevent the condensed droplets from leaking from the distal end 23 of the liquid storage portion 20 to the power supply assembly 200.

The air inlet 31 provides an air flow inlet for external air into the atomizer 100, the air vent 51 is formed on the first sealing member 50, the air vent 51 communicates with the air inlet hole 31 and the atomizing chamber 413, so that when a user sucks, negative pressure is generated inside the atomizing chamber 413, the external air is caused to flow into the atomizing chamber 413 through the air inlet 31 and the air vent 51, then aerosol in the atomizing chamber 413 is carried into the first air flow channel 24 and the second air flow channel 25, then flows into the nozzle 10 through the first air flow channel 24 and the second air flow channel 25, and finally escapes from the atomizer 100 through the air outlet hole 11 of the nozzle 10 for the user to suck, thereby forming a complete air flow path of the atomizer 100, as shown by an arrow route R in fig. 3.

Further, as shown in fig. 3, 8 and 9, the atomizer 100 is further provided with a heat conducting element 90, the heat conducting element 90 comprising a first portion 91 and a second portion 92 extending from the first portion 91 away from the liquid conducting element 41, the first portion 91 being in contact with the liquid conducting element 41, or in some embodiments, the first portion 91 being retained on the liquid conducting element 41, and at least a portion of the second portion 92 extending into the liquid storage chamber 211. The atomizer 100 further comprises an air channel for communicating external air with the liquid storage cavity 211, wherein the air channel is used for supplementing air into the liquid storage cavity 211 so as to relieve negative pressure generated by consumption of liquid matrix in the liquid storage cavity 211, maintain air pressure balance of the liquid storage cavity 211, prevent the liquid matrix from flowing to the atomizing element 40 smoothly due to the negative pressure, and further avoid dry burning of the atomizer 100.

The air channel has an air inlet for the external air and an air outlet for the external air to escape, after which the air escapes from the air outlet into the liquid matrix in the form of bubbles to replenish the liquid reservoir 211 with air. When the liquid matrix in the liquid storage cavity 211 is more viscous, the liquid matrix can block the bubbles from floating up, so that air cannot be smoothly supplied to the liquid storage cavity 211, and when the bubbles are excessively accumulated in the liquid matrix, the bubbles can also cause the liquid matrix to flow to the atomizing element 40, so that dry burning of the atomizing element 40 is easily caused by insufficient liquid supply. By arranging the heat conducting element 90, the first portion 91 of the heat conducting element 90 is in contact with the liquid guiding element 41, the heating element 42 generates heat and transmits the heat to the liquid guiding element 41 during operation, the first portion 91 can absorb the heat on the liquid guiding element 41 and further transmit the heat to the second portion 92, and the liquid matrix in the liquid storage cavity 211 can be heated and diluted under the action of the heat of the second portion 92, so that the blocking of the liquid matrix to bubbles is relieved, the bubbles can float smoothly to supplement air to the liquid storage cavity 211, and the liquid matrix can flow smoothly to the atomizing element 40.

In some embodiments, as shown in fig. 8 and 9, at least a portion of the first portion 91 is sandwiched between the second seal 60 and the liquid guiding element 41, thereby securing the heat conducting element 90 in the atomizer 100. Further, since the second sealing member 60 is made of silica gel or rubber material, the second sealing member 60 has a certain elasticity, when at least a portion of the first portion 91 is clamped between the second sealing member 60 and the liquid guiding member 41, the first portion 91 covers a partial surface of the liquid guiding member 41, and since the liquid guiding member 41 is rigid, the second sealing member 60 will deform under the extrusion force of the heat conducting member 90, and further under the deformation, the first portion 91, the liquid guiding member 41 and the second sealing member 60 of the heat conducting member 90 define a gap 93, and the gap 93 is the air channel as shown in fig. 10.

In some embodiments, as shown in fig. 9, the end 913 of the first portion 91 is exposed to the atomizing chamber 413, and the aerosol released from the atomizing face 412 is typically at a higher temperature, and when the first portion 91 is exposed to the atomizing chamber 413, the high temperature aerosol may further transfer heat to the first portion 91, and the first portion 91 may continue to transfer heat from the aerosol to the second portion 92, thereby further increasing the heat of the second portion 92, which may be advantageous for heating the diluted liquid matrix by the second portion 92.

In some embodiments, as shown in fig. 8 and 9, to allow the heat conducting element 90 to absorb more heat from the liquid conducting element 41 and thereby increase the heat on the second portion 92, the first portion 91 may be configured to contact a different surface of the liquid conducting element 41, the first portion 91 may include a lateral extension 911 extending along the width of the atomizer 100 and a longitudinal extension 912 extending along the length of the atomizer 100, such that the first portion 91 is configured in a bent shape, the lateral extension 911 contacts the liquid intake surface 411 of the liquid conducting element 41, the longitudinal extension 912 contacts the side surface 413 of the liquid conducting element 41 and thereby increase the contact area of the heat conducting element 90 with the liquid conducting element 41 and thereby allow the heat conducting element 90 to absorb more heat from the liquid conducting element 41.

Alternatively, in some embodiments, the first portion 91 may be in contact with only one of the surfaces of the liquid guiding element 41, such as only the liquid suction surface 411 of the liquid guiding element 41, where the first portion 91 may be configured to contact the liquid suction surface 411 in a non-linear manner to increase the contact area to allow more heat to be absorbed by the heat conducting element 90 from the liquid guiding element 41.

In some embodiments, as shown in fig. 9, the heat conducting element 90 is disposed adjacent to the air channel, where the second portion 92 of the heat conducting element 90 may be further configured as a bubble guide, where after air escapes from the air outlet of the air channel and enters the liquid matrix in the form of bubbles 400, the second portion 92 may block the lateral movement of the bubbles, and the bubbles may move only along the second portion 92 in the longitudinal direction, so that the second portion 92 may guide the bubbles into the liquid storage cavity 211, keeping the bubbles away from the liquid suction surface 411, preventing the bubbles 400 from accumulating near the liquid suction surface 411, and further avoiding the accumulated bubbles 400 from obstructing the liquid suction surface 411 from sucking the liquid matrix, resulting in insufficient liquid supply of the atomizing element 40. Further in some embodiments, the second portion 92 extends into the reservoir 211 along the length of the atomizer 100 such that the second portion 92 can quickly direct the gas bubbles 400 into the reservoir 211 away from the liquid suction surface 411 as quickly as possible.

In some embodiments, as shown in fig. 9, the heat conducting element 90 includes a first heat conducting element and a second heat conducting element opposite to the liquid conducting element 41, and the second portion 921 of the first heat conducting element and the second portion 922 of the second heat conducting element extend in parallel toward the liquid storage cavity 211, so that the heat of the liquid conducting element 41 can be transferred more into the liquid storage cavity 211, and thus the viscous liquid matrix can be heated better.

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 41, 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.

In some embodiments, as shown in fig. 1, the atomizer 100 is further provided with a window 12 for observing the remaining liquid amount of the liquid matrix in the liquid storage chamber 211, and a user can observe the current remaining liquid amount of the liquid matrix through the window 12, so as to determine how long the electronic atomization device 100 can still be used. To avoid a user observing the heat conductive element 90 in the reservoir 211 while observing the amount of remaining liquid, the heat conductive element 90 is configured such that it is not observable by the user through the window 12, for example, the height at which the second portion 92 of the heat conductive element 90 extends in the reservoir 211 may be set short, so that the user may be prevented from observing the heat conductive element 90 through the window 12.

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. 11, 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 32 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. 11, 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. 11, 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.

In use, the power supply assembly 200 includes a sensor 250 for sensing the flow of suction air generated by a user drawing through the air outlet 111 of the nebulizer 100, and the controller 240 controls the electrical core 260 to output current to the nebulizer 100 in response to the detection signal of the sensor 250.

Further in the preferred implementation shown in fig. 11, the power supply assembly 200 is provided with a charging interface 270 at the other end facing away from the receiving cavity 210 for charging the battery cells 260.
