[0035] An embodiment of the present application provides an electronic atomization device 100 for atomizing a liquid matrix to generate an aerosol, such as Figure 1 and Figure 2As shown, the electronic atomization device 100 includes a housing 10, a mouthpiece 20, and a base 30. The housing 10 has a first end 11 and a second end 12 that are oppositely arranged in the longitudinal direction. The mouthpiece 20 is installed at the first end 11, and the base 30 is installed at the second end 12 to provide support for the components within the housing 10. An air outlet hole 21 for the aerosol to escape from the electronic atomization device 100 is provided in the mouthpiece 20, and an air inlet hole 31 for external air to enter the electronic atomization device 100 is provided in the base 30. When the user sucks at the air outlet hole 21, the external air enters the electronic atomization device 100 through the air inlet hole 31, and carries the aerosol generated by atomization through the internal air flow channel of the electronic atomization device 100 to the air outlet hole 21 for the user to inhale.

[0036] As Figure 3 and Figure 4 shown, a support frame 40 is provided in the housing 10. The support frame 40 includes a plurality of plate-like bodies 41 that are arranged at intervals and extend longitudinally. The plurality of plate-like bodies 41 are circumferentially arranged around the axis L1 of the support frame 40. A chamber 411 is formed between any two adjacent plate-like bodies 41. An atomizer 50 is fixedly provided in each chamber 411, so that a plurality of atomizers 50 are arranged around the axis L1 of the support frame 40. The support frame 40 and the plurality of atomizers 50 are combined to form the atomization assembly of the electronic atomization device 100. The atomization assembly is used to atomize the liquid matrix to generate aerosol.

[0037] As Figure 3 and Figure 5 shown, a liquid storage chamber is provided in the atomizer 50. A liquid storage member 51 is filled in the liquid storage chamber. The liquid storage member 51 stores the liquid matrix that can be atomized. Moreover, the liquid storage member 51 is formed with an axially penetrating through-hole 52. A rigid air guide tube 53 is provided in the through-hole 52. An atomization element 54 is provided in the air guide tube 53. The atomization element 54 is used to receive the liquid matrix in the liquid storage member 51 and atomize the liquid matrix to form aerosol and release it into the air guide tube 53. An air inlet 55 and an air outlet 56 are respectively provided at both ends of the atomizer 50. The air inlet 55 is used to guide the external air to the atomization element 54, so that the external air carries the aerosol generated after atomization and flows through the air guide tube 53 to the air outlet 56.

[0038] The atomizing element 54 includes a liquid guiding element 541 and a heating element 542 combined on the liquid guiding element 541. The liquid guiding element 541 is provided with an axially penetrating through hole 5411, so that the liquid guiding element 541 has an outer wall and an inner wall. The heating element 542 is arranged in the through hole 5411 and combined on the inner wall of the liquid guiding element 541. At the same time, a through hole 531 is formed in the pipe wall of the air guiding pipe 53, and a part of the liquid guiding element 541 passes through the through hole 531 to contact the liquid storage member 51, so that the liquid guiding element 541 can absorb the liquid matrix held on the liquid storage member 51 and transfer the liquid matrix to the heating element 542. The heating element 542 can heat and atomize the liquid matrix to form an aerosol.

[0039] Both the liquid storage member 51 and the liquid guiding element 541 are made of fiber materials. For example, the liquid storage member 51 and the liquid guiding element 541 can be any one of cotton, non-woven fabric, glass fiber rope, porous ceramic, porous glass, etc. Therefore, the liquid storage member 51 and the liquid guiding element 541 can absorb, transfer the liquid matrix or hold the liquid matrix through the fine voids or microporous structures inside them. Correspondingly, the heating element 542 can be combined on the liquid guiding element 541 or wound around the liquid guiding element 541 by means of printing, deposition, sintering or physical assembly.

[0040] As Figure 6 shown, the atomizer 50 further includes a conductive electrode 57 electrically connected to the heating element 542. The electronic atomization device 100 further includes a main board 70 and a battery cell 60 for supplying electric energy to the atomizer 50. The battery cell 60 is electrically connected to the main board 70. A controller of the electronic atomization device 100 is arranged on the main board 70. Both the conductive electrode 57 and the battery cell 60 are electrically connected to the controller, so that the controller can control the battery cell 60 to supply electric energy to the heating element 542.

[0041] Furthermore, as Figure 6 shown, the electronic atomization device 100 further includes an electrical connection terminal 80 oppositely arranged to the conductive electrode 57. The electrical connection terminal 80 is used to selectively electrically connect to the conductive electrode 57 of one of the atomizers 50 during the rotation of the support frame 40. Furthermore, the controller can control the battery cell 60 to supply electric energy to the heating element 542 through the electrical connection terminal 80 and the conductive electrode 57.

[0042] As Figure 3 shown, when the support frame 50 rotates to electrically connect the conductive electrode 57 of one of the atomizers 50 to the electrical connection terminal 80, the air outlet 56 of the atomizer 50 is docked with the air outlet hole 21 of the mouthpiece 20, so that the aerosol generated by the atomizer 50 can further flow into the air outlet hole 21.

[0043] Please continue to refer to Figure 3 and Figure 4The support frame 40 also includes a plug-in portion 42 extending toward the base 30. The base 30 is provided with a plug-in hole. The plug-in portion 42 is inserted into the plug-in hole and remains fixed. For example, the plug-in portion 32 and the plug-in hole can be fixed by an interference fit, and then the user can operate the base 30 to rotate and thereby drive the support frame 40 to rotate synchronously.

[0044] Please continue reading Figure 3 The electronic atomization device 100 also includes a sensing element 90 electrically connected to the controller, and an identification element 58 arranged on the atomizer 50. When the support frame 40 rotates to make the conductive electrode 57 of one of the atomizers 50 electrically connected to the electrical connection terminal 80, the identification element 58 on the atomizer 50 triggers the sensing element 90 to generate an electrical signal, and the controller can obtain the electrical signal.

[0045] The parameters of the identification element 58 provided on each atomizer 50 are different, and thus the electrical signal generated by the induction element 90 triggered by each identification element 58 is also different. The controller can identify the atomizer 50 electrically connected to the electrical connection terminal 80 according to the difference in the electrical signal.

[0046] In some embodiments, the composition of the liquid matrix stored in each atomizer 50 is different. The controller can identify the composition of the liquid matrix stored in the atomizer 50 by identifying the atomizer 50, and then control the battery 60 to provide corresponding power to the heating element 542, so that the aerosol generated after atomization has a suitable taste. In this way, each atomizer 50 can obtain different powers when connected to the electrical connection terminal 80, and the user can also have different inhalation tastes, thereby improving the playability of the electronic atomization device 100.

[0047] Alternatively, in some embodiments, the aerosol generating device 100 further includes a display device (not shown) electrically connected to the controller, such as a display screen. After the controller identifies the atomizer 50 electrically connected to the electrical connection terminal 80, the controller further obtains the number of inhalation ports of the atomizer 50, and calculates the remaining liquid volume of the liquid matrix according to the number of inhalation ports of the atomizer 50 and the total number of inhalation ports, and displays the remaining liquid volume on the display device for the user to view. In this way, the user can view the remaining liquid volume of each atomizer 50 before operation, thereby improving the user's experience.

[0048] In some embodiments, the sensing element 90 is a color sensor, and the identification element 58 is a color identifier provided on the atomizer 50, such as a color label. Different color labels are provided on each atomizer 50. When one of the atomizers 50 rotates to be electrically connected to the electrical connection terminal 80, the color label of the atomizer 50 triggers the color sensor to generate a corresponding electrical signal and send it to the controller. Since the electrical signals generated by different color labels triggering the color sensor are different, the controller can identify the atomizer 50 currently electrically connected to the electrical connection terminal 80 based on the difference in the electrical signals.

[0049] In some embodiments, the sensing element 90 is a magnetic field sensor, and the identification element 58 is a magnetic member provided on the atomizer 50, such as a magnet. The magnetic induction intensity of the magnetic members provided on each atomizer 50 is different. Further, when the atomizer 50 rotates to be electrically connected to the electrical connection terminal 80, the intensities of the electrical signals generated by the magnetic members on each atomizer 50 triggering the magnetic field sensor are different. Therefore, the controller can identify the atomizer 50 currently electrically connected to the electrical connection terminal 80 based on the difference in the electrical signals. The magnetic field sensor can be any one of a pulsed magnetic field sensor, a giant magnetoresistance magnetic field sensor, a Hall effect sensor, etc. Preferably, a Hall effect sensor is used.

[0050] In some embodiments, as Figure 4 and Figure 6 shown, the atomizer 50 further includes a base 59 for supporting the liquid storage member 51. An electrode hole is provided on the base 59, and one end of the conductive electrode 57 is inserted and fixed in the electrode hole, so that the base 59 holds the conductive electrode 57, and the other end of the conductive electrode 57 extends to the heating element 542. The base 59 is further provided with a mounting groove 591. When the identification element 58 is a magnetic member, the magnetic member can be installed in the mounting groove 591; when the identification element 58 is a color label, the color label can be attached to the outer surface of the base 59.

[0051] In some embodiments, as Figure 3 and Figure 7 shown, the housing 10 defines a first chamber 13 and a second chamber 14 that extend longitudinally and are arranged side by side. The support frame 40 is received in the first chamber 13, and the battery cell 60 and the main board 70 are received in the second chamber 14, thereby reducing the longitudinal extension length of the electronic atomization device 100 to facilitate better holding of the electronic atomization device 100 by the user. Further, for the convenience of electrically connecting the sensing element 90 and the controller on the main board 70, the sensing element 90 is also provided in the second chamber 14.

[0052] And, in some embodiments, as Figure 3 and Figure 7As shown, the housing 10 further includes a partition wall 15 that separates the first chamber 13 and the second chamber 14. A through hole 151 communicating the first chamber 13 and the second chamber 14 is provided on the partition wall 15. When one of the atomizers 50 rotates to be electrically connected to the electrical connection terminal 80, the sensing element 90 and the identification element 58 are located on both sides of the through hole 151, and the identification element 58 can trigger the sensing element 90 to generate an electrical signal through the through hole 151.

[0053] In some embodiments, the sensing element 90 is disposed adjacent to the electrical connection terminal 80. Thus, when one of the atomizers 50 rotates to be electrically connected to the electrical connection terminal 80, the distance between the sensing element 90 and the identification element 58 of the atomizer 50 is relatively close, thereby improving the accuracy of identification.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; under the idea of the present application, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above. For the sake of brevity, they are not provided in detail; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present application.
