[0041] Please refer to Figures 1-6, the present utility model provides an aerosol generator, which includes a housing 1, a main control board 2, at least two atomizing cartridges 3, a switching component 4, and a mouthpiece 5. An installation groove 14 is provided at the first end of the housing 1, and an air inlet 121 communicating with the installation groove 14 is provided at the second end. The main control board 2 is installed inside the housing 1. At least two of the atomizing cartridges 3 are loaded in the installation groove 14, communicate with the air inlet 121, and are electrically connected to the main control board 2. The switching component 4 is fastened in the installation groove 14 and is electrically connected to the main control board 2. The mouthpiece 5 rotatably covers the switching component 4 and closes the open end of the installation groove 14. And an elastic conductive member 7 elastically abutted against the switching component 4 is provided on one side of the mouthpiece 5 located in the installation groove 14, and the switching component 4 is provided with at least two contact members 421 adapted to the elastic conductive member 7 corresponding to the two atomizing sections. When the mouthpiece 5 rotates to communicate with one of the atomizing cartridges 3, it drives the elastic conductive member 7 to contact and conduct with the contact member 421 corresponding to the one atomizing cartridge 3, so as to transmit a signal for powering on the one atomizing cartridge 3 to the main control board 2. By rotating the mouthpiece 5 to drive the elastic conductive member 7 to contact and conduct with different contact members 421 on the switching component 4, corresponding electrical signals are generated to the main control board 2, thereby realizing the switching of each atomizing cartridge 3.

[0042] In some embodiments, such as Figure 2 , Figure 3 and Figure 5As shown, the housing 1 includes a cylindrical housing body 11 and a bottom cover 12. A tray 13 is provided inside the housing body 11. The outer periphery of the tray 13 is connected to the inner wall of the housing body 11, and the plane where the tray 13 is located is perpendicular to the axial direction of the housing body 11. The tray 13 divides the housing body 11 into two spaces. Among them, the space above the tray 13 forms the first end of the housing 1, and the space below the tray 13 forms the second end of the housing 1. The tray 13 and the side wall of the housing body 11 enclose the installation groove 14 at the first end. That is, the side wall of the housing body 11 forms the side wall of the installation groove 14, and the tray 13 forms the bottom wall of the installation groove 14 to carry the atomization cartridge 3. The bottom cover 12 is installed at the second end and closes the opening at the second end. Thus, the bottom cover 12, the side wall of the housing body 11, and the tray 13 enclose an installation cavity 19. The installation cavity 19 is used to install components such as the main control board 2, the battery element electrically connected to the main control board 2, and / or the display component and the button component. In practical applications, the air inlet 121 can be provided on the bottom cover 12 or the side wall of the housing body 11. The tray 13 is provided with at least two ventilation holes 131 corresponding to the atomization cartridge 3. The ventilation holes 131 communicate the air inlet 121 with the installation groove 14. When the atomization cartridge 3 is loaded into the installation groove 14, the atomization cartridge 3 is communicated with the ventilation holes 131. External air enters the housing 1 from the air inlet 121 and then enters the atomization cartridge 3 through the ventilation holes 131 and participates in atomization.

[0043] In some embodiments, please refer to Figure 3 , the cross-section of the installation groove 14 is circular. A plurality of partition plates 15 extending in the axial direction are provided in the installation groove 14. The bottom end of the partition plate 15 is perpendicularly connected to the tray 13. One side of the partition plate 15 coincides with the central axis of the installation groove 14 and is connected to other partition plates 15, and the other side extends toward the side wall of the installation groove 14 and is connected to the side wall. Each partition plate 15 is radially distributed around the central axis of the installation groove 14. Adjacent two partition plates 15, the side wall and the bottom wall (i.e., the tray 13) of the installation groove 14 form a slot 16. That is to say, the bottom surface of the slot 16 is formed by the tray 13, and the side surface of the slot 16 is surrounded by adjacent two partition plates 15 and the side wall of the installation groove 14. For example, two partition plates 15 enclose two slots 16, three partition plates 15 enclose three slots 16... and so on. The ventilation holes 131 are respectively provided at the bottoms of the slots 16, that is, the ventilation holes 131 correspond to the slots 16 one by one. Therefore, when each subsequent slot 16 is loaded with the atomization cartridge 3, each atomization cartridge 3 is respectively communicated with the ventilation holes 131 provided in each slot 16 for air intake.

[0044] In some embodiments, the atomizing cartridge 3 includes a hollow housing 31, a first sealing seat 32 provided with a first through hole, a second sealing seat 33 provided with a second through hole, an atomizing tube 35 provided with an oil passing hole, an atomizing assembly (not shown in the figure), and a first conductive member (not shown in the figure). The first sealing seat 32 is sealingly installed at the first end of the housing 31, the second sealing seat 33 is sealingly installed at the other end of the housing 31, and the first through hole and the second through hole are respectively communicated with the housing 31. Both ends of the atomizing tube 35 are inserted into the first through hole and the second through hole respectively to form an atomizing channel 34 penetrating the housing 31 and an oil storage cavity surrounding the atomizing channel 34. The atomizing assembly is accommodated in the atomizing tube 35 and exposed from the oil passing hole. The oil storage cavity can directly store the oil liquid or be filled with an oil storage member 36 absorbing the oil liquid. The part of the atomizing assembly exposed from the oil passing hole absorbs the oil liquid in the oil storage cavity, then heats and atomizes the oil liquid, and the generated aerosol flows into the mouthpiece 5 through the first through hole for the user to inhale. The first conductive member is installed on the second sealing seat 33, with one end electrically connected to the atomizing assembly and the other end exposed outside the housing 31 from the second sealing seat 33 for electrical connection with a power source. Correspondingly, at least two second conductive members electrically connected to the battery element can be provided on the housing 1. When the atomizing cartridge 3 is loaded into the slot 16, the first conductive member is electrically connected to the corresponding second conductive member.

[0045] In some embodiments, as Figures 2-3 shown, the switching component 4 includes a bracket 41 and a transfer board 42. The shape of the bracket 41 is adapted to the shape of the installation groove 14. Therefore, when the installation groove 14 is a circular groove 411, the outer periphery of the bracket 41 also has a corresponding circular structure. The bracket 41 is accommodated in the installation groove 14 and fixedly connected to the side wall of the installation groove 14. In practical applications, an annular limiting groove 415 can be provided on the outer periphery of the bracket 41, and at least one limiting protrusion 142 extending in the circumferential direction is provided on the installation groove 14 corresponding to the annular limiting groove 415. The limiting protrusion 142 is accommodated in the annular limiting groove 415 to limit the axial displacement of the bracket 41. At the same time, at least one limiting buckle 416 protrudes from one end of the bracket 41 close to the mouthpiece 5 toward the side wall of the installation groove 14, and at least one slot 141 is provided on the side wall of the installation groove 14 corresponding to the limiting buckle 416. The limiting buckle 416 is accommodated in the corresponding slot 141 to limit the radial displacement of the bracket 41. In this way, the bracket 41 is inserted into the installation groove 14 through the cooperation between the annular limiting groove 415 and the limiting protrusion 142, and between the limiting buckle 416 and the slot 141.

[0046] Further, the bracket 41 is located above the at least two atomizer cartridges 3, and a circular groove 411 for mounting the adapter plate 42 is provided on the side facing away from the atomizer cartridges 3. At least two ventilation columns 413 protrude from the bottom wall of the circular groove 411, and the ventilation columns 413 correspond to the atomizer cartridges 3 one by one. Each ventilation column 413 is respectively communicated with the atomizer cartridge 3. Preferably, each ventilation column 413 is coaxially arranged with the corresponding ventilation hole 131. In this way, when the atomizer cartridge 3 is loaded into the slot 16, both ends of the atomizer cartridge 3 are coaxially communicated with the ventilation hole 131 and the ventilation column 413 respectively, so as to achieve the maximum intake air volume and facilitate the smooth flow of air. In practical applications, at least two ventilation columns 413 are centrally symmetrically distributed around the center of the circular groove 411, and each ventilation column 413 encloses a circular ring concentric with the circular groove 411. Correspondingly, the mouthpiece 5 is provided with an air outlet 521, and the rotation track of the air outlet 521 coincides with the circular ring. In this way, when the mouthpiece 5 rotates, it drives the air outlet 521 to rotate. Since the rotation track of the air outlet 521 coincides with the circular ring, the air outlet 521 can rotate to communicate with each ventilation column 413, so that the mouthpiece 5 is communicated with each atomizer cartridge 3 through rotation.

[0047] In some embodiments, the adapter plate 42 is provided with an avoidance hole 422 adapted to the ventilation column 413. When the adapter plate 42 is placed in the circular groove 411, the adapter plate 42 is concentric with the circular groove 411, and the avoidance hole 422 is sleeved on the ventilation column 413. In this embodiment, the ventilation column 413 is used to limit the adapter plate 42 to prevent the adapter plate 42 from rotating relative to the bracket 41.

[0048] In some embodiments, the contact member 421 is provided on the side of the adapter plate 42 facing the mouthpiece 5, and the side facing away from the mouthpiece 5 is electrically connected to the main control board 2. In practical applications, the adapter plate 42 and the main control board 2 can be conducted through a wire. Alternatively, a positive electrode pad and a negative electrode pad can be provided on the adapter plate 42, and a positive electrode pin 17 and a negative electrode pin 18 corresponding to the positive electrode pad and the negative electrode pad are provided in the installation groove 14, and the adapter plate 42 and the main control board 2 are conducted through the pins and wires. In this way, when the contact member 421 on the adapter plate 42 is contacted and conducted, the generated electrical signal can be transmitted to the main control board 2.

[0049] In some embodiments, please refer to Figure 2 、 Figure 4 and Figure 5, the suction nozzle 5 includes a suction nozzle body 51. The suction nozzle body 51 covers the opening end of the installation groove 14, and a connecting column 53 protrudes towards the installation groove 14, and a suction part 52 protrudes away from the installation groove 14. The air outlet 521 penetrates through the suction nozzle body 51 and the suction part 52. Correspondingly, the bracket 41 protrudes towards the suction nozzle 5 with a sleeve 412 coaxial with the installation groove 14. The inner wall of the sleeve 412 is provided with a first latching portion 4121 along the circumferential direction, and the end of the connecting column 53 is provided with a second latching portion 531. The connecting column 53 extends into the sleeve 412, and the second latching portion 531 is rotatably engaged with the first latching portion 4121. When the suction nozzle 5 is rotated, the suction nozzle 5 rotates around the sleeve 412. In this embodiment, through the sliding engagement between the first latching portion 4121 and the second latching portion 531, the displacement of the suction nozzle 5 in the axial direction is restricted, preventing the suction nozzle 5 from detaching from the switching assembly 4 during the rotation process.

[0050] Furthermore, the aerosol generator further includes a soft rubber part 6. The soft rubber part 6 is clamped between the suction nozzle 5 and the switching assembly 4. On the one hand, the switching assembly is protected by the soft rubber part, and on the other hand, the rotation resistance of the suction nozzle is increased, thereby increasing the damping feel. Specifically, the soft rubber part 6 covers one end of the sleeve 412 facing the suction nozzle 5 and fits against the adapter plate 42 to partially cover the adapter plate 42. Thus, an annular groove 43 coaxial with the sleeve 412 is formed between the soft rubber part 6 and the side wall of the installation groove 14. The side wall of the installation groove 14 forms the outer ring side wall of the annular groove 43, the outer circumference of the soft rubber part 6 forms the inner ring side wall of the annular groove 43, and the part of the adapter plate 42 not covered by the soft rubber part 6 forms the bottom wall of the annular groove 43. The contact part 421 is provided on the part of the adapter plate 42 not covered, that is, the contact part 421 is arranged on the bottom wall of the annular groove 43 and exposed from the opening of the annular groove 43 for the elastic conductive part to contact. Correspondingly, the suction nozzle body 51 is provided with the elastic conductive part 7 facing the contact plate. When the suction nozzle 5 covers the switching assembly 4, the elastic conductive part 7 is accommodated in the annular groove 43 and elastically abuts against the adapter plate 42. When the suction nozzle 5 is forced to rotate, it drives the elastic conductive part 7 to rotate in the annular groove 43 to contact and conduct with different contact parts 421, thereby transmitting corresponding electrical signals to the main control board 2.

[0051] It is worth noting that the contact parts 421 correspond to the atomization cartridges 3 one by one. When each contact part 421 is contacted and conducted, electrical signals corresponding to the atomization cartridges 3 one by one are transmitted to the main control board 2. Thus, the main control board 2 can transmit corresponding control signals according to the received electrical signals to control the corresponding atomization cartridges 3 to be powered on.

[0052] In some embodiments, please refer toFigure 2 and Figures 4-6 The contact member 421 includes a first contact portion 4211 and a second contact portion 4212 that are printed at intervals on the adapter board 42. The elastic conductive member 7 includes a fixed end 71 and a first elastic end 72 and a second elastic end 73 that extend from both ends of the fixed end 71 respectively. The fixed end 71 is fixedly connected to the nozzle 5. In practical applications, a fixing post 55 can be provided on the nozzle 5, a connection hole can be provided on the fixed end 71, and a connecting member passes through the connection hole and is fixedly connected to the fixing post 55 to fasten the fixed end 71 to the nozzle 5. One ends of the first elastic end 72 and the second elastic end 73 away from the fixed end 71 are elastically abutted against the adapter board 42. When the nozzle 5 rotates and drives the elastic conductive member 7 to rotate until the first elastic end 72 abuts against the first contact portion 4211 and the second elastic end abuts against the second contact portion 4212, the first contact portion 4211 and the second contact portion 4212 are in contact conduction and transmit an electrical signal to the main control board 2. In practical applications, different electrical signals can be generated by setting the resistance value between the first contact portion 4211 and the second contact portion 4212 to be used to distinguish the power-on signals corresponding to different atomizer cartridges 3.

[0053] In some embodiments, the contact member 421 may include a capacitor printed on the adapter board 42. Correspondingly, the elastic conductive member 7 includes a fixed end 71 fixedly connected to the nozzle 5 and an elastic arm extending from the fixed section. The elastic arm is elastically abutted against the adapter board 42. When the nozzle 5 rotates and drives the elastic conductive member 7 to rotate until the elastic arm abuts against the capacitor, the elastic conductive member 7 is in contact conduction with the contact member 421 and transmits an electrical signal to the main control board 2.

[0054] In some embodiments, in order to facilitate positioning the rotation of the nozzle 5, a first positioning member 54 can be provided on the side of the nozzle 5 facing the switching assembly 4. Correspondingly, a matching second positioning member 414 is provided on the switching assembly 4. Among them, there are at least two second positioning members 414, and they correspond to at least two atomizer cartridges 3 one by one. When the nozzle 5 rotates until the first positioning member 54 cooperates with the second positioning member 414, the nozzle 5 communicates with one of the atomizer cartridges 3 and drives the elastic conductive member 7 to be in contact conduction with the contact member 421 corresponding to the one atomizer cartridge 3, so as to transmit the signal for powering on the one atomizer cartridge 3 to the main control board 2. In practical applications, the first positioning member 54 is a positioning protrusion provided on the nozzle 5, and the second positioning member 414 is a positioning groove provided on the end face of the opening end of the circular groove 411. The positions of the positioning grooves correspond to the respective slots 16 one by one. When the nozzle 5 rotates, it drives the positioning protrusion to rotate until the positioning protrusion snaps into the corresponding positioning groove, that is, the switching of the atomizer cartridge 3 is realized.

[0055] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
