As shown in fig. 3 and 6, a receiving chamber 212 extends from the bottom wall 2113 in a direction away from the liquid storage chamber 211, the receiving chamber 212 being defined by the bottom wall 2113 and a second side wall including two extending walls 2114 extending from the bottom wall 2113 in a direction away from the liquid storage chamber 211 and being oppositely disposed, and two inner walls 26 being oppositely disposed in a thickness direction of the liquid storage portion 20, that is, the receiving chamber 212 being defined by the bottom portion 2113, the oppositely disposed extending walls 2114 and the oppositely disposed inner walls 26, at least a portion of the atomizing element 30 being located in the receiving chamber 212 so as to receive the liquid matrix in the liquid storage chamber 211.

In order to avoid leakage of the liquid matrix through the assembly gap between the atomizing element 30 and the inner wall of the accommodating chamber 212, a first sealing member 50 is disposed between the atomizing element 30 and the liquid storage portion 20, the first sealing member 50 is formed with an accommodating chamber, the atomizing element 30 is tightly fitted in the accommodating chamber, and the first sealing member 50 may be made of a flexible material such as silica gel or rubber, so that the first sealing member 50 may be elastically abutted between the atomizing element 30 and the inner wall of the accommodating chamber 212, and the first sealing member 50 may provide a seal between the atomizing element 30 and the liquid storage portion 20.

As shown in fig. 3, 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 to conduct current, the ends of the conductive electrode 62 abutting against the atomizing element 30 to support it for positioning in the housing chamber 212 as described above.

When the user performs suction by using the electronic atomization device 300, external cold air enters the atomization chamber 313 and is mixed with high-temperature aerosol in the atomization chamber 313, the high-temperature aerosol is condensed to form condensed liquid drops when meeting the external cold air, and the third sealing member 40 forms a seal to prevent the dropped condensed liquid from leaking from the distal end 23 of the liquid storage part 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 guide hole 41 is formed on the third sealing member 40, the air guide hole 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 guide hole 41, then aerosol in the atomization chamber 313 is carried 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. 3.

As shown in fig. 6, the bottom wall 2113 further includes a vent hole 2115 provided at a distance from the liquid outlet 2111, the vent hole 2115 being communicated to the liquid storage chamber 211, and at the same time, the inner surface of the housing chamber 212 is provided with a groove 2121, and the groove 2121 and the outer surface of the first seal member 50 define an air passage communicating the vent hole 2115 with the outside air. When the user sucks, the volume of the gas in the liquid storage cavity 211 is increased along with the consumption of the liquid matrix in the liquid storage cavity 211, negative pressure is generated in the liquid storage cavity 211, and the air can be supplemented to the liquid storage cavity 211 through the air channel and the vent hole 2115 to maintain the air pressure balance inside and outside the liquid storage cavity 211, so that the liquid matrix can continuously and smoothly flow to the atomizing element 30, and dry burning caused by insufficient liquid supply of the atomizing element 30 is avoided.

In addition, the vent hole 2115 and the liquid outlet 2111 are arranged at intervals, so that the air supplementing path and the liquid supplying path are separated, external air does not enter the liquid storage cavity 211 through the liquid outlet 2111 any more, and air bubbles formed when the external air enters the liquid matrix can be prevented from being accumulated at the liquid outlet 2111, so that the liquid outlet 2111 is prevented from being blocked by the accumulated air bubbles.

In some embodiments, as shown in fig. 7, the groove 2121 includes a first portion 2121a disposed on a second side wall of the accommodating chamber 212, and a second portion 2121b and a third portion 2121c disposed on the bottom wall 2113, the third portion 2121c being connected to the vent hole 2115, the second portion 2121b being connected to the first portion 2121a and the third portion 2121c, and the second portion 2121b and the third portion 2121c being perpendicular to each other in order to mitigate the first seal 50 from being partially squeezed into the groove 2121 to affect smooth entry of outside air into the liquid storage chamber 211.

It should be noted that, in some embodiments, a groove may be formed on the outer surface of the first seal member 50, and the groove 2121 is not required to be formed on the inner surface of the accommodating chamber 212, and thus the groove on the outer surface of the first seal member 50 and the inner surface of the accommodating chamber 212 define the air channel.

In some embodiments, as shown in fig. 6, 7 and 8, the vent holes 2115 are adjacent to the second side wall, as opposed to the edges of the vent holes 2115, i.e., the vent holes 2115 are disposed adjacent to the extension wall 2114 or the inner wall 26 of the reservoir 20, so that the vent holes 2115 are as far away from the liquid outlet 2111 as possible so that bubbles formed when outside air forms into the liquid matrix are farther away from the liquid outlet 2111, which is advantageous for preventing the bubbles from clogging the liquid outlet 2111. And, in some embodiments, when the vent hole 2115 is disposed adjacent to the second side wall, a longitudinally extending groove may be disposed on the second side wall, the groove being directly connected to the vent hole 2115, in such a way that the time for the external air to enter the liquid storage cavity 211 may be shortened, so that the external air is timely replenished into the liquid storage cavity 211.

And, in some embodiments, as shown in fig. 7, the vent hole 2115 is disposed adjacent to the extension wall 2114, and since the distance d1 between the extension wall 2114 and the liquid outlet 2111 is greater than the distance d2 between the inner wall 26 of the liquid reservoir 20 and the liquid outlet 2111, disposing the vent hole 2115 adjacent to the extension wall 2114 may provide a greater distance of the vent hole 2115 from the liquid outlet 2111, which may be more advantageous for preventing the formation of bubbles from the outside air to accumulate in the liquid outlet 2111.

In some embodiments, as shown in fig. 8, the vent holes 2115 include two, and two vent holes 2115 are provided at both sides of the liquid outlet 2111, so that the external air can be guided into the liquid storage cavity 211 at both sides of the liquid outlet 2111, in such a way that more external air can be guided into the liquid storage cavity 211 on the one hand; on the other hand, when one of the air passages is blocked, the other air passage may still guide the external air into the liquid storage chamber 211 to maintain the air pressure balance inside and outside the liquid storage chamber 211. Of course, in some embodiments, more vent holes 2115 may be provided on both sides of the liquid outlet 2111.

Further in some embodiments, as shown in fig. 9, the vent hole 2115 includes a first portion 2115a and a second portion 2115b that are longitudinally distributed, the first portion 2115a providing for external air to enter into the vent hole 2115, the second portion 2115b providing for external air to escape the vent hole 2115, i.e., the second portion 2115b is closer to the reservoir 211 than the first portion 2115a, and the aperture of the first portion 2115a is smaller than the aperture of the second portion 2115b, so that external air can more smoothly pass through the vent hole 2115.

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. 10, 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 implementation shown in fig. 10, 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.
