The inventors of the present disclosure have combined the advantageous points of both and invented an electronic atomizing device 30.

[0033] In some embodiments, the electronic atomizing system 1 includes an aerosol-generating article 20 and an electronic atomizing device 30; the electronic atomizing device 30 includes an atomizing assembly 10, each of the atomizing assembly 10 and the aerosol-generating article 20 accommodating an aerosol-generating substrate; the aerosol-generating substrate can be a solid substrate in a plant leaf type having a specific fragrance or a liquid substrate containing a combination of flavors and fragrances; the aerosol-generating substrate can generate an aerosol under a heating condition. The electronic atomizing device 30 is fixedly connected or detachably connected to the aerosol-generating article 20 for providing energy to the aerosol-generating article 20, to heat and atomize the aerosol-generating substrate stored within the aerosol-generating article 20. The atomizing assembly 10 in the electronic atomizing device 30 is further configured to heat and atomize the aerosol-generating substrate. The selection is based on the actual situation, for example, when there is a liquid substrate stored in the atomizing assembly 10 and a solid substrate stored in the aerosol-generating article 20, the electronic atomizing device 30 is configured to heat the liquid substrate in the atomizing assembly 10 as well as the aerosol-generating article 20 by means of a heating assembly. For another example, the atomizing assembly 10 and the aerosol-generating article 20 are both configured to heat and atomize a liquid aerosol-generating substrate, and the user may choose to store different flavors of the liquid aerosol-generating substrate in the electronic atomizing system 1, and may either vape two flavors of aerosol at the same time or choose one of them according to preference, thereby improving the user's experience.

[0034] Referring to FIG. 3, in some embodiments, the atomizing assembly 10 includes a liquid storage chamber 11, an atomizing seat 12, an atomizing core 13, and an atomizing channel 14.

In conjunction with FIG. 6, the electronic atomizing device 30 further includes a control circuit board 31, a battery 32, and a housing 33; where the control circuit board 31 and the battery 32 are accommodated in the housing 33; the control circuit board 31 is configured to control the battery 32 to supply power to the atomizing assembly 10 and to control the battery 32 to heat the aerosol-generating article 20 through the heating assembly. The control circuit board 31 includes multiple control modules that can control an operating temperature of the atomizing assembly 10 and a heating temperature of the aerosol-generating article 20, respectively.

[0039] In some embodiments, in conjunction with FIGS. 6 to 8, the electronic atomizing device 30 further includes a connection seat 34 and a heating assembly 35.

[0040] The connection seat 34 is arranged in the housing 33 and is electrically connected to the control circuit board 31 and the atomizing assembly 10, for enabling to supply power to the atomizing assembly 10. In a specific embodiment, the connection seat 34 is arranged with a first thimble (not shown), and the first thimble is electrically connected to the battery 32 through the control circuit board 31. The atomizing seat 12 in the atomizing assembly 10 is arranged with planar electrical-connection contacts (not shown), the contacts are electrically connected to the atomizing core 13, and the first thimble is electrically connected to the contacts when the atomizing assembly 10 is assembled into the housing 33, thereby enabling the battery 32 to power and heat the atomizing core 13. The connecting seat 34 may further be arranged with necessary elements such as a microphone, an air-conducting slot, and a magnetic attraction member.

[0041] The heating assembly 35 is arranged in the housing 33 and is electrically connected to the control circuit board 31 for heating the aerosol-generating article 20. The heating method of the heating assembly 35 may be electromagnetic heating, resistance heating, or infrared heating, etc. When the heating method of the heating assembly 35 is electromagnetic heating, the heating assembly 35 includes a coil 351 around a circumference of the aerosol-generating article 20, and the containment tube 21 in the aerosol-generating article 20 is a metal material or a metal material is arranged in the substrate section 22 of the aerosol-generating article 20, to generate heat in the electromagnetic field. When the heating method of the heating assembly 35 is infrared heating, the heating assembly 35 includes a tubular heating element (not shown) around the circumference of the aerosol-generating article 20 and an infrared material coated on an outer surface of the heating element. When the heating method of the heating assembly 35 is resistive heating, the heating assembly 35 includes a center needle-like or center sheet-like heating body 352, and the heating body 352 is inserted into the substrate section 22 of the aerosol-generating article 20. The heating method and shape of the heating assembly 35 may be selected according to actual needs and will not be discussed herein.

[0042] Referring to FIGS. 3 to 10, in some embodiments, the housing 33 has a containment cavity 36 and a containment slot 37. A slot wall of the containment slot 37 defines a first air inlet hole 38. The containment cavity 36 is configured to accommodate the atomizing assembly 10, and the first air inlet hole 38 is configured to communicate with an air outlet of the atomizing channel 14 of the atomizing assembly 10. The containment slot 37 is configured to accommodate the aerosol-generating article 20, and the first air inlet hole 38 is further accommodate to be connected with the hollow section 23 of the aerosol-generating article 20, such that the first aerosol generated by the atomizing assembly 10 enters the hollow section 23 of the aerosol-generating article 20 through the first air inlet hole 38 and mixes with the second aerosol generated by the aerosol-generating article 20 to form the mixed aerosol for vaping by the user. Specifically, a bottom or side wall of the containment slot 37 defines the first air inlet hole 38, and a side wall of the hollow section 23 of the aerosol-generating article 20 defines a second through hole 26; the first aerosol generated in the atomizing assembly 10 is introduced into the hollow section 23 of the aerosol-generating article 20 through the first air inlet hole 38 and the second through hole 26, and is mixed at the hollow section 23 with the second aerosol generated by the aerosol-generating article 20, and then exported through the filter section 24. Through the above arrangement, the first aerosol generated by the atomizing assembly 10 and the second aerosol generated by the aerosol-generating article 20 are mixed in the hollow section 23 in the aerosol-generating article 20, and then jointly exported through the filter section 24. Compared to a traditional simple series connection of the atomizing assembly 10 and the aerosol-generating article 20, the electronic atomizing system 1 of the present disclosure may avoid a poor taste of the first aerosol caused by the first aerosol entering the entering the substrate section 22 in the aerosol-generating article 20 and being heated twice; further, the electronic atomizing system 1 may avoid a loss of atomized amount caused by the first aerosol adhering to the solid aerosol-generating substrate within the substrate section 22 in the aerosol-generating article 20.

[0043] Specifically, the electronic atomizing system 1 containing both the first aerosol and the second aerosol may maximize the fragrance and atomized amount of the aerosol-generating substrate, thereby increasing user satisfaction.

[0044] In some embodiments, referring to FIG. 7, the first air inlet hole 38 is defined on the bottom wall of the containment slot 37, and a first air-conducting channel 39 is formed between the aerosol-generating article 20 and the containment slot 37. The first air inlet hole 38 is in communication with the second through hole 26 on the side wall of the hollow section 23 through the first air-conducting channel 39. In some embodiments, a bottom wall of the aerosol-generating article 20 near the containment slot 37 is arranged with a support member to be inserted in the first air inlet hole 38, for supporting the aerosol-generating article 20, such that the aerosol-generating article 20 is disposed at a spaced-apart distance from the bottom wall of the containment slot 37. In the embodiments, a slot opening of the containment slot 37 is further arranged with a sealing structure 371 to prevent the first aerosol from escaping.

[0045] In other embodiments, referring to FIGS. 6 and 8, the first air inlet hole 38 is defined on the side wall of the containment slot 37 and close to the hollow section 23 of the aerosol-generating article 20, to be in communication with the second through hole 26 on the side wall of the hollow section 23. In this way, a movement path of the first aerosol can be reduced to avoid cleaning problems caused by condensate due to temperature loss of the first aerosol adheres to the airflow channel, and avoid the user experience from being affected caused by the user inhaling the condensate of the first aerosol. In the embodiments, an outer surface of the aerosol-generating article 20 may be attached to an inner surface of the containment slot 37 (as shown in FIG. 8), with the first air inlet hole 38 and the second through hole 26 directly aligned and communicated. Alternatively, the aerosol-generating article 20 is spaced apart from the containment slot 37 (as shown in FIG. 7), with the first air inlet hole 38 and the second through hole 26 communicated through the first air-conducting channel 39. When the aerosol-generating article 20 is spaced apart from the containment slot 37, the slot opening of the containment slot 37 is arranged with the sealing structure 371 to prevent the first aerosol from escaping through the slot opening of the containment slot 37.

[0046] In some embodiments, the side wall of the containment slot 37 defines an annular depression 41 to be in communication with the second through hole 26 on the side wall of the hollow section 23, and the first air inlet hole 38 is in communication with the annular depression 41. Specifically, the first aerosol is introduced into the annular depression 41 through the first air inlet hole 38, enters the second through hole 26 after diffusing through the annular depression 41 around the side wall of the aerosol-generating article 20, and is introduced into the hollow section 23. Considering the large atomized amount of the generated first aerosol, in order to increase the introduction efficiency, the second through hole 26 may be in plural, and the multiple second through holes 26 are spaced apart around the side wall of the aerosol-generating article 20. The multiple second through holes 26 are all aligned and in communication with the annular depression 41.

[0047] The first air inlet hole 38 may be defined on a bottom wall or a side wall of the annular depression 41. In some embodiments, the first air intake hole 38 is defined on the bottom wall of the annular depression 41. In this way, the fabrication process as well as the machining difficulty may be simplified.

[0048] In some embodiments, referring to FIG. 6, an outer surface of the side wall of the containment slot 37 is arranged with a second air-conducting channel 42 in communication with the first air inlet hole 38, and an end of the second air-conducting channel 42 away from the first air inlet hole 38 is connected to the air outlet of the atomizing assembly 10. The first aerosol generated in the atomizing assembly 10 flows into the mouth of the user through the atomizing channel 14, the second air-conducting channel 42, the hollow section 23 of the aerosol-generating article 20, and the filter section 24. The second air-conducting channel 42 may be an air-conducting tube or a hollow protrusion for easy insertion into the air outlet of the atomizing channel 14 to ensure a good sealing of the channel.

[0049] In some embodiments of the present disclosure, referring further to FIG. 9, the housing 33 includes an outer shell 44 and an inner tube 45, which may be detachably connected or integrally molded between the outer shell 44 and the inner tube 45. The outer shell 44 defines the containment cavity 36, the atomizing assembly 10 is accommodated in the containment cavity 36, and the aerosol-generating article 20 is inserted into the inner tube 45. The inner tube 45 is disposed at an end of the outer shell 44 and defines the containment slot 37. The aerosol-generating article 20 is inserted into the inner tube 45, and the length of the aerosol-generating article 20 is greater than the length of the inner tube 45, such that the filter section 24 can serve as a nozzle for the user to vape, and the disassembly of the aerosol-generating article 20 will be easier.

[0050] In some embodiments, when the heating method of the heating assembly 35 is electromagnetic heating, the coil 351, serving as the heating assembly 35, is disposed on an outer surface of the inner tube 45 and is electrically connected to the battery 32 through the control circuit board 31. The containment tube 21 in the aerosol-generating article 20 is made of a metal material or a metal material is arranged in the substrate section 22 in the aerosol-generating article 20, such as, copper, platinum, iron, etc. When the control circuit board 31 controls the battery 32 to supply power to the coil 351, the metal material cooperates with the coil 351 to heat and atomize the solid aerosol-generating substrate to generate the second aerosol.

[0051] In other embodiments, when the heating method of the heating assembly 35 is infrared heating, an inner surface of the inner tube 45 is coated with an infrared material or the inner tube 45 itself is made of an infrared material, and the infrared material emits infrared rays under an energized condition to heat and atomize the solid aerosol-generating substrate to generate the second aerosol. Alternatively, the inner tube 45 itself is made of an infrared material to serve as the heating assembly 35.

[0052] In other embodiments, when the heating method of the heating assembly 35 is resistance heating, the heating assembly 35 may be a heating element arranged on the inner tube 45 and electrically connected to the battery 32 through the control circuit board 31. When the control circuit board 31 controls the battery 32 to supply power to the heating element, the heating element generates heat to atomize the solid aerosol-generating substrate to generate the second aerosol. Alternatively, the inner tube 45 itself is made of an electrically conductive material to serve as the heating assembly 35.

[0053] In some embodiments, the outer shell 44 defines a first aperture (not shown), the first aperture being in communication with the liquid storage chamber 11 of the atomizing assembly 10.
