The seal 50 may be made of a flexible, soft gel material, such as a silicone or rubber material.

As shown in fig. 4, the atomizing element 40 includes a liquid guiding element 41 and a heating element 42 combined on the liquid guiding element 41, wherein the liquid guiding element 41 can be made of a hard capillary structure such as porous ceramics, porous glass, etc., and has a plurality of micropore structures inside, and according to the use situation, the atomizing element includes a first surface 411 and a second surface 412 which are oppositely arranged along the length direction of the atomizer 100, the first surface 411 faces the liquid guiding hole 221 for sucking up the liquid matrix, the heating element 42 is combined on the second surface 412 for heating the atomized liquid matrix, and the liquid matrix can flow to the first surface 411 through the liquid guiding hole 221 and is conducted to the second surface 412 through the internal micropore structure of the liquid guiding element 41.

The heating element 42 is preferably formed on the second 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 second surface 412, and the heating element has the effects of high atomization efficiency, less heat loss, dry burning prevention or great dry burning reduction, etc. In some embodiments, the heating element 42 may take a variety of other forms, for example, the heating element 42 may be a sheet-shaped heating element with a specific pattern bonded to the second surface 412, or other forms such as a heating mesh, a disk-shaped heating element with a heating wire spirally formed, 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 onto the second surface 412, the heating element 42 of the second surface 412 heats and atomizes the liquid matrix and releases the aerosol generated after atomization from the second surface 412.

As shown in fig. 4, the liquid guiding element 41 further comprises a side surface 413 extending between the first surface 411 and the second surface 412, the side surface 413 is formed with a notch 4131 penetrating between the first surface 411 and the second surface 412, and the notch 4131 is concave inward from the side surface 413 toward the center of the liquid guiding element 41, so that the liquid guiding element 41 presents a C-shaped or U-shaped cross section. After the aerosol is released from the second surface 412, the aerosol enters the air duct 21 through the notch 4131, and by providing the notch 4131 on the liquid guiding element 41, the condensate formed after the high-temperature aerosol and the cold air are mixed can be effectively relieved from blocking the airflow channel of the atomizer 100.

In some embodiments, as shown in fig. 4, the side surface 413 includes a planar portion 4132 and a cambered surface portion 4133, the planar portion 4132 having a first end 41321 and a second end 41322, the notch 4131 extending from the planar portion 4132 toward the cambered surface portion 4133, and the cambered surface portion 4133 extending between the first end 41311 and the second end 41312, thereby configuring the liquid guiding element 41 in a "C" shape, which shape of the liquid guiding element 41 can facilitate assembly.

Further in some embodiments, as shown in fig. 4 and 6, the notch 4131 is disposed in a central region of the planar portion 4132 such that the notch 4131 is disposed directly opposite the air duct 21, and aerosol can quickly enter the air duct 21 after escaping from the notch 4131, increasing the rate at which aerosol escapes from the atomizer 100.

As shown in fig. 8, the power supply mechanism used with the atomizer 100 includes an internal threaded electrode 230 and a central electrode 220, and when the atomizer 100 is screwed with the power supply mechanism, the internal threaded electrode 230 of the power supply mechanism is screwed with the external threaded electrode 31 of the atomizer 10, and the central electrode 220 of the power supply mechanism abuts against the movable electrode 32 of the atomizer 100, so that the power supply mechanism is electrically connected with the atomizer 100. Since the size of the externally threaded electrode 31 of the atomizer 100 is generally a common size, which results in the internally threaded electrode 230 of the power mechanism being substantially uniform when the power mechanism is designed by different atomizer manufacturers, and different in the height of the center electrode 220, the movable electrode 32 of the atomizer 100 is movable in order to enable the atomizer 100 to match power mechanisms of different heights. Specifically, when the atomizer 100 is screwed with the power supply mechanism, the central electrode 220 of the power supply mechanism abuts against the movable electrode 32, and applies a pressing force to the movable electrode 32, and the movable electrode 32 can move along the length direction of the atomizer 100 under the action of the pressing force, so as to adapt to different heights of the central electrode 220 of the power supply mechanism.

To conduct electrical energy from the power supply mechanism to the heating element 42, an electrical connection is provided between the heating element 42 and the electrode of the atomizer 100, which is a rigid conductive material, such as a metal, carbon-based material, conductive polymer, or the like. One end of the electrical connector extends to the second surface 412 to electrically connect with the heating element 42, while the electrical connector also provides support for the liquid guiding element 41, so that the liquid guiding element 41 is further firmly accommodated in the sealing member 50.

And a conductive elastic member 70 is arranged between the first electric connector 61 and the movable electrode 32, one end of the elastic member 70 is abutted against the side surface of the first electric connector 61, and further is electrically connected with the first electric connector 61 through the side surface, and the other end of the elastic member 70 is abutted against the top of the movable electrode 32, so that the elastic electric connection between the first electric connector 61 and the movable electrode 32 can be realized through the elastic member 70, and the stability of the electric connection between the first electric connector 61 and the movable electrode 32 is improved.

In this embodiment, since one end of the elastic member 70 is electrically connected to the side surface of the first electrical connector 61, the elastic member 70 has no longitudinal pressure on the first electrical connector 61, and when the atomizer 100 is adapted to the power supply mechanism of the center electrode with different heights, although the movable electrode 32 moves longitudinally, the longitudinal movement does not have a large influence on the contact resistance between the elastic member 70 and the first electrical connector 61, that is, the contact resistance between the first electrical connector 61 and the movable electrode 32 does not have a large influence, so that the problem that it is difficult to accurately measure the resistance of the heating element 42 due to a large change in the contact resistance is effectively alleviated, and it is difficult to accurately measure the temperature of the heating element 42.

It should be noted that, in some embodiments, the elastic member 70 may not be disposed between the first electrical connector 61 and the movable electrode 32, for example, the first electrical connector 61 may be further extended, so that the side surface of the first electrical connector 62 is directly contacted with the side surface of the movable electrode 32 to realize electrical connection, and when the movable electrode 32 moves along the length direction of the atomizer 100, the movable electrode 32 does not have a longitudinal pressure on the first electrical connector 61, and the contact resistance between the first electrical connector 61 and the movable electrode 32 may be less affected.

In some embodiments, as shown in fig. 6, a support 80 is supported on the base 30, the support 80 being disposed opposite the liquid-guiding element 41 and defining an atomization chamber 81 with the liquid-guiding element 41, where the aerosol escaping from the second surface 412 is released. The air inlet 34 of the atomizer 100 is formed on the base 30, when the user sucks at the air outlet 11 of the suction nozzle 10, external air enters the atomizer 100 from the air inlet 34, in order to introduce the external air into the atomizing chamber 81, a gap 82 is maintained between the bracket 80 and the base 30, the gap 82 is in fluid communication with the atomizing chamber 81, so that the external air enters the atomizing chamber 81 through the gap 82 after entering the atomizer 100, and aerosol in the atomizing chamber 81 is carried into the air duct 21 through the groove 4131 of the liquid guide element 41, and finally flows into the air outlet 11 of the suction nozzle 10 through the air duct 21, so that an air flow channel of the atomizer 100 is formed, as shown by an arrow route R in fig. 6.

In some embodiments, as shown in fig. 2 and 5, a plug hole 83 is formed on the bracket 80, and a resisting boss 611 extends laterally on the first electrical connector 61, and a portion of the first electrical connector 61 is inserted into the plug hole 83 while the resisting boss 611 abuts against a surface of the bracket 80, so that the bracket 80 holds the first electrical connector 61.

Further, in some embodiments, as shown in fig. 2, a housing cavity 84 is formed on the bracket 80, an end of the elastic member 70 abutting against the first electrical connector 61 abuts against a top wall of the housing cavity 84, the plugging hole 83 communicates with the housing cavity 84, and a part of the first electrical connector 61 is exposed to the housing cavity 84 through the plugging hole 83, so that the elastic member 70 abuts against the first electrical connector 61 to achieve electrical connection. The other end of the elastic member 70 abuts against the top of the movable electrode 32, so that when the elastic member 70 is a compression spring, the elastic member 70 can be compressed between the top wall of the accommodating chamber 84 and the top of the movable electrode 32, and when the movable electrode 32 moves in the longitudinal direction, the movable electrode 32 applies a pressing force to the elastic member 70, and the elastic member 70 elastically deforms and pushes against the movable electrode 32 under the action of an elastic restoring force, thereby improving the stability of the electrical connection between the movable electrode 32 and the first electrical connector 61.

Further in some embodiments, as shown in fig. 6, a vent hole 85 extends from the surface of the support 80 toward the liquid guiding element 41, and the vent hole 85 is offset from the center of the atomizing chamber 81, so as to avoid condensation droplets formed after the high-temperature aerosol in the atomizing chamber 81 encounters the outside cold air to condense, falling into the vent hole 85, thereby causing the vent hole 85 to be blocked. The bottom end face of the movable electrode 32 is formed with a first opening 321, the side wall of the movable electrode 32 is formed with a second opening 322, the first opening 321 and the second opening 322 are communicated through a hollow area inside the movable electrode 32, the second opening 322 is communicated with a vent hole 85, the first opening 321 is communicated with an air flow sensor in a power supply mechanism, and when a user sucks at the air outlet 11, the air flow sensor in the power supply mechanism can sense negative pressure in the atomizing chamber 81 through the vent hole 85, so that the air flow sensor is triggered.

As the liquid matrix in the liquid storage cavity 24 gradually dissipates due to the suction of the user, a negative pressure is generated in the liquid storage cavity 24, and the negative pressure can cause the liquid matrix in the liquid storage cavity 24 to flow to the atomizing element 40 to be atomized, so that dry combustion of the atomizing element 40 is easy to occur, and therefore an air channel for guiding external air into the liquid storage cavity 24 is also usually provided in the atomizer 100 to relieve the negative pressure in the liquid storage cavity 24.

Specifically, as shown in fig. 7, the bottom wall 22 is further provided with an air vent 222, the air vent 221 and the air vent 222 are spaced apart, the air vent 222 is used for guiding the external air into the liquid storage cavity 24, and the separate air vent 222 is provided to efficiently guide the external air into the liquid storage cavity 24. Further, as shown in fig. 7, a sealing member 2221 is disposed in the air vent 222, the sealing member 2221 may be made of silica gel or rubber material, and the sealing member 2221 is in interference fit with the inner wall of the air vent 222, so as to prevent the liquid matrix in the liquid storage cavity 24 from leaking through the air vent 222. The inner wall of the liquid guide hole 222 is provided with a longitudinally extending groove 2222, and the groove 2222 serves as an air passage for guiding outside air into the liquid storage chamber 24. Alternatively, the grooves 2222 may be formed on the outer wall of the sealing member 2221.
