In addition, referring to fig. 2, an embodiment of the present application further provides an aerosol raw product 10, where the aerosol raw product 10 includes a coating layer 11 and an atomizing area 12, the atomizing area 12 is located inside the coating layer 11 and is surrounded by the coating layer 11, and the material of the atomizing area 12 is the atomizing substrate 100 of any of the above embodiments.

The atomizing area 12 of the aerosol production product 10 is formed by using the aerosol substrate 100, and the aerosol is formed by self-heating by the atomizing area 12 as a heating resistor. Compared with the traditional aerosol raw product depending on the heat conduction of the heating body, the aerosol raw product 10 has the advantages of high heating speed and uniform heating, high temperature rise and cooling speed, and can stop pumping immediately, so that the problems of inconsistent taste and low utilization rate of the atomizing part caused by nonuniform heating of the atomizing part are solved, and the problem of low atomizing response speed caused by low heating speed is also solved.

In some embodiments, the aerosol-generating article 10 is in the form of a column or a sheet. It is understood that in other embodiments, the shape of the aerosol-forming article 10 is not limited to the above, and may be adjusted according to specific conditions.

Specifically, the coating layer 11 serves as an outer package of the atomizing area 12. In some embodiments, the cover 11 is at least one of a paper wrapper and a plastic. It is to be understood that the material of the clad 11 is not limited to the above. In some embodiments, the atomizing area 12 is cylindrical, and correspondingly, the coating 11 is cylindrical, and the aerosol-forming product 10 is also cylindrical. In one embodiment, the cross section of the atomizing area 12 gradually increases or decreases along the central axis of the atomizing area 12, and the longitudinal section of the atomizing area 12 is an isosceles trapezoid. In the embodiment shown in fig. 2, the longitudinal section of the atomizing area 12 is isosceles trapezoid, and the longitudinal section of the coating layer 11 is triangle-shaped on both sides of the atomizing area 12. It is to be understood that the shapes of the atomizing area 12, the coating layer 11, and the aerosol production product 10 are not limited to the above, and may be adjusted as the case may be.

In some embodiments, cladding layer 11 is a conductive cladding layer 11. Specifically, the material of the coating layer 11 is at least one selected from a conductive metal simple substance (e.g., aluminum foil, copper foil, etc.), conductive mica, graphite, a conductive alloy, silicon carbide, a conductive fiber, and a conductive resin. It is understood that when the coating 11 is a conductive coating 11, the coating 11 can be used as an electrode structure of the aerosol raw product 10 for electrically connecting with the power source 22, and in this case, it is not necessary to provide an additional electrode structure on the atomizing area 12 or an electrode structure on the electronic atomizer. Of course, in this case, the coating layer 11 only encloses the atomizing area 12 for safety. It will be appreciated that the cover 11 may also serve as a packaging layer for the aerosol-forming article 10 to enclose other components of the aerosol-forming article 10, if other security measures are present at this time.

In some embodiments, the resistance of the atomizing area 12 is 0.4 Ω to 2 Ω. The resistance of the atomizing part 12 is set as above, so that the heating circuit of the existing atomizer can be adapted; the resistance of the atomizing area 12 set as described above is suitable for atomizing the atomizing medium 110. In an alternative specific example, the resistance of the atomizing area 12 is 0.5 Ω, 1 Ω, 1.5 Ω, or 1.8 Ω. It is understood that in other embodiments, the electrical resistance of the atomizing area 12 can be adjusted according to the type of atomizing substrate 100 and the content of atomizing substrate 100.

Referring to fig. 3, in one embodiment, the aerosol substrate 100 is in the form of granules. When a plurality of the aerosol substrates 100 in a particulate form are formed into the aerosol preform 10, electrical connection is achieved by forming contact points between adjacent aerosol substrates 100. When energized, the plurality of granulated atomization substrate 100 forms a complete conductive network that effects heating. Also, upon heating of the particulate aerosol substrate 100, each aerosol substrate 100 may approximate a "core" of atomization, which is easier to release due to the larger specific surface area of the particles as compared to the direct solid or mass; during the suction, air passes through the gaps between the particles to carry the aerosol containing the active ingredient out.

In some embodiments, the atomizing area 12 is formed by an atomizing substrate 100. That is, the conductive material 120 in the atomizing area 12 is uniformly distributed.

Referring again to fig. 2, in some embodiments, the aerosol-generating article 10 further includes a mouthpiece 13, and the mouthpiece 13 is used for drawing the aerosol generated by the atomizing area 12. Optionally, a portion of the mouthpiece 13 is located inside the covering 11 and is wrapped by the covering 11. In this case, the coating layer 11 also serves as an outer package of the entire aerosol-generating article 10. In one embodiment, the aerosol generation is cylindrical, and the aerosol-generating article 10 comprises an atomizing part 12 and a mouthpiece 13 arranged in sequence on the central axis of the coating 11 and defined by the coating 11. There is a space between the atomizing area 12 and the mouthpiece 13. Further, a filter material (e.g., acetate fiber) is also provided inside the mouthpiece 13. Further, an aerosol cooling element is provided between the atomizing area 12 and the mouthpiece 13 to cool the aerosol. It will be appreciated that in some embodiments, the coating 11 only covers the atomizing area 12, and that the cooling element, mouthpiece 13, etc. are surrounded by a wrapper located outside the coating 11.

In some embodiments, the aerosol generating article 10 further comprises an electrode structure for electrically connecting the atomizing area 12 to the power source 22. Specifically, the electrode structure includes a first electrode for electrical connection with the positive electrode of the power source 22 and a second electrode spaced from the first electrode for electrical connection with the negative electrode 24 of the power source 22. In one embodiment, one end of the first electrode is in direct contact with the atomizing area 12 (e.g., located in the atomizing area 12), and the other end protrudes from the atomizing area 12; one end of the second electrode is also in direct contact with the atomizing area 12 (e.g., located in the atomizing area 12), and the other end also protrudes from the atomizing area 12. It is understood that in some embodiments, the aerosol-generating article 10 does not include an electrode structure. At this time, the atomizing area 12 is electrically connected to the power source 22 by being in direct contact with the electrical connection of the electronic atomizer.

Referring to fig. 4 (the dotted arrow in fig. 4 represents the airflow direction), the present application also provides an electronic atomizer including a housing 21 and a power source 22. The housing 21 has a receiving cavity adapted to the aerosol-generating article 10 of any of the above embodiments; the power supply 22 is positioned in the shell 21, and the power supply 22 supplies power for atomization of the atomization part 12; when the aerosol-generating product 10 is located in the accommodating cavity, the atomizing part 12 can be electrically connected with the power source 22 to atomize and form aerosol.

Specifically, the electronic atomizer includes a positive electrode 23 and a negative electrode 24 spaced apart from the positive electrode 23. One end of the positive electrode 23 is electrically connected with the power supply 22, and the other end is electrically connected with the aerosol raw product 10; one end of the negative electrode 24 is electrically connected with the power source 22, and the other end is electrically connected with the aerosol raw product 10, and the power source 22, the positive electrode 23, the aerosol raw product 10 and the negative electrode 24 form a loop. In the illustrated embodiment, one end of the positive electrode 23 is electrically connected to the power source 22, and the other end is electrically connected to the clad 11; one end of the negative electrode 24 is electrically connected to the power source 22, and the other end is electrically connected to the cladding layer 11. The power source 22, the positive electrode 23, the coating layer 11, the atomizing part 12 and the negative electrode 24 form a circuit.

In some embodiments, the electronic atomizer further includes a temperature sensor for detecting the temperature of the atomizing area 12 and feeding back the detection result to the controller, and a controller for controlling the power supply from the power source 22 to the atomizing area 12 according to the detection result fed back by the temperature sensor, thereby adjusting the temperature of the atomizing area 12.

In some embodiments, the electronic atomizer further comprises a suction nozzle and an air flow passage. Optionally, a mouthpiece is located on the housing 21 for drawing aerosol. An air inlet hole 211 for air to enter the housing 21 is opened on the housing 21. During suction, air (for example, air) enters from the air inlet holes 211 and then carries the aerosol formed by the atomizing part 12 out of the suction nozzle. Of course, the mouthpiece 13 need not be provided with the aerosol preform 10 at this point. Further, the electronic atomizer further comprises a cooling member adjacent to the suction nozzle for cooling the aerosol. For the same reason, the aerosol-forming article 10 may not include a cooling element.

The electronic atomizer is adapted to the aerosol product 10, and the utilization efficiency of the electric energy is high.

In addition, the present application also provides an atomization system, which includes the aerosol raw product 10 and the electronic atomizer adapted to the aerosol raw product 10, when the aerosol raw product 10 is located in the accommodating cavity of the electronic atomizer, the atomization portion 12 of the aerosol raw product 10 can be electrically connected to the power source 22 to atomize and form aerosol.

The atomization system comprises the aerosol production product 10 and the electronic atomizer, and has the corresponding advantages of the aerosol production product 10 and the electronic atomizer.
