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.

As shown in fig. 2, a second support 22 is further disposed in the main body 20, and the second support 22 is disposed opposite to the liquid guiding element 31 and defines an atomization chamber 313 with the liquid guiding element 31, so that the aerosol escaping from the atomization surface 312 is released. The second support 22 is provided with a conductive electrode 221, and the conductive electrode 221 extends longitudinally and abuts against the atomizing surface 312, so that the conductive electrode 221 is electrically connected with the heating element 32 on the atomizing surface 312, and meanwhile, the conductive electrode 221 can provide support for the liquid guiding element 31 due to the abutting of the conductive electrode 221 and the atomizing surface 312, so that the atomizing element 30 can be further maintained.

In order to form a complete airflow path of the electronic atomizing device 100, the housing of the main body 20 is provided with an air inlet hole 214, the second support 22 is formed with an air guide hole 222 communicated with an atomizing chamber 313, and the air guide hole 222 is communicated with the air inlet hole 214, so that when a user sucks on the aerosol outlet 11, external air enters the electronic atomizing device 100 through the air inlet hole 214, then enters the atomizing chamber 313 through the air guide hole 22 of the second support 22, and carries aerosol in the atomizing chamber 313 into the airflow channel 213, finally enters the aerosol outlet 11 through the airflow channel 213 for the user to suck, and the complete airflow path is shown by an arrow route R1 in fig. 5.

As the liquid matrix in the liquid storage cavity 211 gradually dissipates due to the suction of the user, a negative pressure is generated in the liquid storage cavity 211, and the negative pressure can cause the liquid matrix in the liquid storage cavity 211 to flow onto the atomizing element 30, so that the atomizing element 30 is dry-burned due to the lack of liquid, and therefore an air channel for guiding external air into the liquid storage cavity 211 is further generally provided in the electronic atomizing device 100 to relieve the negative pressure in the liquid storage cavity 211.

As an example of the air passage, as shown in fig. 7, the air passage 12 is formed on the mouthpiece portion 10, the air passage 12 has an air inlet 121 and an air outlet 122, the air inlet 121 communicates with the aerosol outlet 11, and thus the air inlet 121 communicates with the outside air, the air outlet 122 communicates with the liquid storage chamber 211, and the air outlet 122 maintains a certain gap 2114 with the liquid surface of the liquid substrate, so as to prevent the outside air from entering into the liquid substrate to form bubbles, and prevent the bubbles from accumulating in the liquid substrate and thus affecting the smooth flow of the liquid substrate to the atomizing element 30. In some embodiments, both the aerosol outlet 11 and the air channel 12 are longitudinally extending so that outside air can quickly pass through the aerosol outlet 11 and the air channel 12 into the reservoir 211.

It should be noted that, in some embodiments, the air inlet 121 of the air channel 12 may not be in communication with the aerosol outlet 12, that is, the air channel 12 may be a separate air channel.

The movable member 123 and the elastic member 124 are disposed in the air channel 12, the movable member 123 is connected or abutted with the elastic member 124, the movable member 123 is kept at the first position under the elastic force of the elastic member 124, as shown in fig. 7, at this time, the movable member 123 seals the air channel 12 to prevent the external air from entering the liquid storage cavity 211, and the liquid substrate in the liquid storage cavity 211 is prevented from being in contact with the external air for a long time to cause deterioration. The elastic member 124 may be any one of a spring, a silicone, a rubber, a spring plate, a cantilever, etc., and only the elastic member 124 can provide an elastic force.

When the user sucks on the aerosol outlet 11, as the liquid matrix is consumed, the volume of the air in the liquid storage cavity 211 increases, the air pressure in the liquid storage cavity 211 decreases to generate negative pressure, so that the air pressure difference between the air pressure of the external air and the air pressure in the liquid storage cavity 211 increases, and when a certain value is increased, the movable member 123 moves from the first position to the second position against the elastic force of the elastic member 124 under the action of the air pressure difference on both sides of the movable member, at this time, the air channel 12 is opened, as shown by an arrow path R2 in fig. 8, the external air can enter the gap 2114 to maintain the air pressure balance in the liquid storage cavity 211. Meanwhile, in the process of moving the movable member 123 from the first position to the second position, the movable member 123 applies a pressing force to the elastic member 124, so that the elastic member 124 is elastically deformed.

Further, since the external air has entered the liquid storage cavity 211, the air pressure difference between the liquid storage cavity 211 and the external air will gradually decrease, that is, the air pressure difference between the two sides of the movable member 123 will gradually decrease, and when the air pressure difference between the two sides of the movable member 123 gradually decreases to a certain value, the elastic member 124 pushes the movable member 123 from the second position to the first position under the elastic restoring force, so that the movable member 123 reseals the air channel 12.

As can be easily understood from fig. 2, the air channel 12 is disposed at the first end of the liquid storage cavity 211, and the atomizing element 30 is disposed at the second end of the liquid storage cavity 211, so that external air enters the liquid storage cavity 211 through the upper end of the electronic atomizing device 100, and external air can be prevented from entering the liquid guide hole 2113 first, and then enters the liquid storage cavity 211 through the liquid guide hole 2113, so that bubbles are easily accumulated on the liquid absorbing surface 311 of the liquid guide element 30, the liquid absorbing surface 311 is affected to continuously absorb the liquid matrix, and dry burning of the atomizing element 30 is easily generated.

In some embodiments, the first position is provided with a limiting portion, and the limiting portion limits the movable member 123, so that the movable member 123 is kept in the first position under the elastic force of the elastic member 124.

Further in some embodiments, when the moveable member 123 abuts the connection portion 126, a surface of the moveable member 123 is adapted to conform to a surface of the connection portion 126, thereby sealing the air passage 12. Preferably, in order to reduce the resistance generated by the contact of the movable member 123 with the inner wall of the air passage 12 when the movable member 123 moves in the air passage 12, the movable member 123 is configured into a sphere, and the surface of the limiting portion 125 is adapted to be an arc surface, so that the sphere of the movable member 12 is adapted to fit with the arc surface of the limiting portion 125 to realize sealing.
