[0060] Please refer to FIG. 1 to FIG. 3, the atomization appliance provided by the embodiment of the present application is described. The atomization appliance comprises an atomizer support 100 and a power supply assembly 200, the atomizer support 100 is used for accommodating a plurality of atomizers 2; the atomizer 2 has a first air inlet 21, the first air inlet 21 is used for passing external airflow into the atomizer 2; at least part of the atomizer support 100 and the power supply assembly 200 can relatively move, so as to switch the electrical connection state of the power supply assembly 200 and at least one atomizer 2, and switch the air communication state of the first air inlet 21 and external airflow.

[0061] Wherein, at least part of the atomizer support 100 and the power supply assembly 200 can relatively move, which can be that the atomizer support 100 and the entire power supply assembly 200 can relatively move, or the atomizer support 100 and some or several components on the power supply assembly 200 can relatively move. In addition, the above relative movement can be relative rotation, or relative movement.

[0062] The atomization appliance in the embodiment of the present application can accommodate a plurality of atomizers 2 through the atomizer support 100, and the tastes of the atomizers 2 can be the same or different, so that the atomization appliance can carry a plurality of atomizers 2 to meet the smoking needs of users, and can also increase the selectivity of users on the taste. At the same time, at least part of the atomizer support 100 and the power supply assembly 200 can relatively move, so as to switch the electrical connection state of the power supply assembly 200 and at least one atomizer 2, and switch the air communication state of the first air inlet 21 and external airflow, that is, only one of the atomizer support 100, the power supply assembly 200 or the local part of the power supply assembly 200 needs to be driven to move, so as to switch the use state of at least one atomizer 2, which is simple to operate.

[0063] In the present application, when the state of the atomizer 2 is switched, the relative rotation or movement of the atomizer support 100 and the entire power supply assembly 200 can be driven to switch the state of at least one atomizer 2, or the relative rotation or movement of the atomizer support 100 and the local part of the power supply assembly 200 can be driven to switch the state of at least one atomizer 2.

[0064] The above cases are described in detail through a plurality of embodiments.

[0065] Embodiment one:

[0066] Please refer to FIG. 1 to FIG. 3, the power supply assembly 200 includes an electrode support 210 and an electrode 220 arranged on the electrode support 210, the electrode support 210 can move relative to the atomizer support 100 to synchronously switch the electrical connection state of the electrode 220 and the at least one atomizer 2 and the gas communication state of the first air inlet 21 and the external airflow. In this embodiment, the relative movement between the electrode support 210 in the power supply assembly 200 and the atomizer support 100 is used to realize the state switching of the at least one atomizer 2. The structures (for example, the battery 280) in the power supply assembly 200 other than the electrode support 210 and the electrode 220 can be relatively fixed with the electrode support 210, and then the whole power supply assembly 200 moves relative to the atomizer support 100. The structures (for example, the battery 280) in the power supply assembly 200 other than the electrode support 210 and the electrode 220 can also move relative to the electrode support 210, and then the partial power supply assembly 200 moves relative to the atomizer support 100.

[0067] In this embodiment, the electrode support 210 and the atomizer support 100 can rotate relative to each other to synchronously switch the electrical connection state of the electrode 220 and the at least one atomizer 2 and the gas communication state of the first air inlet 21 and the external airflow.

[0068] Specifically, please refer to FIG. 1 and FIG. 2, the power supply assembly 200 further includes a battery 280 and a main shell 400, the battery 280 is fixedly installed on the electrode support 210, the main shell 400 is arranged outside the electrode support 210, the main shell 400 is clamped with the electrode support 210, and the main shell 400 abuts against the atomizer support 100 along the axial direction of the atomizer. When the state switching is performed, the atomizer support 100 or the main shell 400 can be rotated externally to make the atomizer support 100 and the whole power supply assembly 200 rotate relative to each other, so as to realize the state switching of the at least one atomizer 2.

[0069] In this embodiment, please refer to FIG. 1 to FIG. 3, the atomizer further includes a rotating shaft 800, the rotating shaft 800 is connected with the atomizer support 100, an axle hole 810 is formed in the electrode support 210, and the rotating shaft 800 is inserted into the axle hole 810 to form a rotating fit with the axle hole 810, so as to form the rotating connection between the atomizer support 100 and the electrode support 210. When the state switching is performed, only the atomizer support 100 or the electrode support 210 needs to be manually rotated.

[0070] In this embodiment, the rotating shaft 800 is located at the central position of the electrode support 210. It can be understood that in other embodiments, the rotating shaft 800 can also be arranged eccentrically. In addition, the rotating shaft can also not be arranged, for example, the atomizer support 100 rotates with the electrode support 210 as the rotating shaft, or the electrode support 210 rotates with the atomizer support 100 as the rotating shaft.

[0071] In this embodiment, the rotating shaft 800 is integrally connected with the atomizer support 100. In other embodiments, the rotating shaft 800 can also be connected by screw locking, interference fit, bonding or welding.

[0072] In this application, in order to ensure that the electrode 220 forms a good connection with the atomizer 2, the electrode 220 is generally designed to protrude slightly from the contact plane, which is the surface of the electrode support 210 facing the atomizer support 100. However, during the relative rotation of the atomizer support 100 and the electrode support 210, the electrode 220 will continuously rub against the end surface of the atomizer support 100, resulting in large rotational friction, poor user experience, and also causing the atomizer to wear. In addition, the hard scraping of the gold plating layer by the rotating electrode 220 can easily wear off, causing the contact resistance to increase, affecting the heating and atomization performance, and also affecting the service life of the spring needle.

[0073] In order to improve the friction state of the electrode 220 on the electrode support 210, the electrode 220 is preferably a compressible electrode, such as a spring needle or a spring sheet.

[0074] In this application, the atomizer support 100 can avoid the electrode 220 during relative rotation with the electrode support 210. Specifically, the atomizer support 100 can rotate relative to the electrode 220 from a first position to a second position to a third position; when the atomizer support 100 is in the first position relative to the electrode 220, one of the atomizers 2 is electrically connected with the electrode 220; when the atomizer support 100 is in the second position relative to the electrode 220, the atomizer support 100 avoids the electrode 220; when the atomizer support 100 is in the third position relative to the electrode 220, the other atomizer 2 is electrically connected with the electrode. It should be noted that when the electrode support 210 is provided with a group of electrodes 220, during the rotation of the atomizer support 100 relative to the electrode 220 from the first position to the third position, the electrode 220 is switched from electrical connection with one of the atomizers 2 to electrical connection with an adjacent atomizer 2; when the electrode support 210 is provided with two or more groups of electrodes 220, during the rotation of the atomizer support 100 relative to the electrode 220 from the first position to the third position, the electrode 220 is switched from electrical connection with one of the atomizers 2 to electrical connection with one or more atomizers 2 therebetween.

[0075] It should be noted that relative motion refers to the relative motion of the atomizer support 100 and the electrode support 210 in the transverse direction; and the atomizer support 100 avoiding the electrode 220 refers to the atomizer support 100 avoiding the electrode 220 in the longitudinal direction. The longitudinal direction refers to the distribution direction of the atomizer support 100 and the electrode support 210, i.e. the height direction and the axial direction of the entire atomizer; and the transverse direction refers to the direction perpendicular to the longitudinal direction.

[0076] The relative position between the electrode 220 and each atomizer 2 is as follows. Specifically, the atomizer 2 comprises an electric connection column 23. When the electrode 220 and the atomizer 2 abut along the axial direction of the atomizer, that is, when the electric connection column 23 abuts against the electrode 220, the electrode 220 and the atomizer 2 form an electric connection, and the power supply assembly 200 supplies power to the atomizer 2 through the electrode 220. After the electrode holder 210 and the atomizer holder 100 generate a preset relative movement, the atomizer 2 moves away from the electrode 220, and another atomizer 2 adjacent to the atomizer 2 moves above the electrode 220 to abut against the electrode 220 along the axial direction of the atomizer, so as to supply power to the adjacent atomizer 2 through the electrode 220. In use, the relative movement between the atomizer holder 100 and the electrode holder 210 is driven to enable the atomizer 2 to be electrically connected to the electrode 220 each time.

[0077] When the atomizer holder 100 is rotated relative to the electrode 220 from the first position to the third position, the atomizer holder 100 is just rotated by a preset angle, that is, the electric connection state of each atomizer 2 is switched once, specifically, the electric connection between the electrode 220 and one atomizer 2 is switched to the electric connection between the electrode 220 and another atomizer 2. In addition, when the atomizer holder 100 is in the second position relative to the electrode 220, the atomizer holder 100 and the electrode holder 210 are in a relative movement state, and the electrode 220 is not electrically connected to the atomizer 2 at this time.

[0078] In this embodiment, the electrode 220 can be electrically connected to one of the atomizers 2 when the atomizer holder 100 is in the first position and the third position relative to the electrode 220, and the atomizer holder 100 avoids the electrode 220 when the atomizer holder 100 is in the second position relative to the electrode 220, so that the electrode 220 does not interfere with the atomizer holder 100 during the relative rotation of the atomizer holder 100 and the electrode holder 210, thereby reducing the wear of the electrode 220.

[0079] In addition, it should be noted that the atomizer holder 100 avoids the electrode 220, which can be that the atomizer holder 100 and the electrode holder 210 slide relative to each other along the axial direction of the atomizer to avoid the electrode 220, or that a avoiding groove is formed in the position corresponding to the movement track of the electrode 220 to avoid the electrode 220.

[0080] First, one of the ways in which the atomizer support 100 avoids the electrode 220 is described in detail. Specifically, the atomizer support 100 and the electrode support 210 are relatively slid along the axial direction of the atomizer while rotating to make the atomizer support 100 avoid the electrode 220. The above arrangement makes the user only need to perform a rotating operation, i.e., the atomizer support 100 is relatively slid away from the electrode support 210 in the process of rotation to make the atomizer support 100 avoid the electrode 220, so as to reduce or even avoid the friction between the electrode 220 and the atomizer support 100, reduce the wear degree of the gold-plated layer of the electrode 220, improve the heating and atomization performance of the atomizer 2, and also improve the service life of the electrode 220, without the need to pull out the atomizer support 100 with one hand and then rotate the atomizer support 100 with the other hand, thereby improving the use convenience of the aerosol generating device and improving the user experience.

[0081] Specifically, please refer to FIG. 4. The atomizer support 100 has a first matching surface 181, and the electrode support 210 has a second matching surface 201 that is slidably matched with the first matching surface 181. The first matching surface 181 and the second matching surface 201 are relatively arranged along the axial direction of the atomizer. The second matching surface 201 has a first position 2011, a second position 2012, and a third position 2013. When the first matching surface 181 is located at the first position 2011, the atomizer support 100 is in a first orientation relative to the electrode 220. When the first matching surface 181 is located at the second position 2012, the atomizer support 100 is in a second orientation relative to the electrode 220. When the first matching surface 181 is located at the third position 2013, the atomizer support 100 is in a third orientation relative to the electrode 220.

[0082] The first position 2011, the second position 2012, and the third position 2013 are positions of the second matching surface 201 corresponding to the atomizer support 100 rotating from the first orientation to the third orientation relative to the electrode 220, and the first position 2011, the second position 2012, and the third position 2013 are sequentially distributed along the circumferential direction of the atomizer. In the process of relatively rotating the atomizer support 100 and the electrode support 210 by a predetermined angle, the first matching surface 181 is slid from the first position 2011 to the second position 2012 of the second matching surface 201, and then from the second position 2012 to the third position 2013. By changing the relative matching positions of the first matching surface 181 and the second matching surface 201, the electrode support 210 and the atomizer support 100 are made to approach or move away from each other along the axial direction of the atomizer, thereby avoiding the electrode 220. Of course, in other embodiments, the second matching surface 201 can be formed on the atomizer support 100, and the first matching surface 181 can be formed on the electrode support 210.

The end surface of the electrode support 210 is the highest surface 2018, when the guide protrusion 180 slides into the guide groove 202, the end surface of the atomizer support 100 abuts against the highest surface 2018, at this time the atomizer 2 is electrically connected with the electrode 220, when the guide protrusion 180 slides out of the guide groove 202 and abuts against the highest surface 2018, the atomizer support 100 and the atomizer 2 are lifted by a predetermined height, and the atomizer support 100 avoids the electrode 220.

[0089] In the embodiment, the number of guide grooves 202 is the same as the number of atomizers 2, and the number of guide protrusions 180 is the same as the number of atomizers 2.

[0105] Embodiment three:

[0106] The technical features of the atomization device in this embodiment are basically the same as those in the atomization device in Embodiment 1, and the difference lies in that, in this embodiment, referring to FIG. 8, the electrode support 210 is rotationally connected with the atomizer support 100.

In this embodiment, the main shell 400 is fixedly connected with the atomizer support 100, and the atomizer support 100 rotates relative to the part (the electrode support 210 and the electrode 220) of the power supply assembly 200 to switch the use state of at least one atomizer 2.

[0107] In this embodiment, referring to FIGS. 8 and 9, two conductive circular rings 214 are formed on the side of the electrode support 210 facing the main shell 400, and the two conductive circular rings 214 are respectively electrically connected with the two electrodes 220.

In the process of rotating the electrode support 210, the conductive columns 1200 elastically abut on different positions of the conductive circular rings 214, so that the electrodes 220 can keep electrical connection with the circuit board 610 in the process of rotating the electrode support 210. In this embodiment, since the wires are connected between the relatively fixed conductive columns 1200 and the circuit board 610, the wires will not be twisted and bent due to the rotation of the electrode support 210, thereby ensuring the stability of the electrical connection.

[0110] In the embodiment, the suction nozzle 310 is connected with the atomizer support 100, and the suction nozzle 310 is relatively fixed with the atomizer support 100.

[0111] Embodiment four:

[0112] In the embodiment, the suction nozzle 310 is connected with the atomizer support 100, and the suction nozzle 310 is relatively fixed with the atomizer support 100.

[0113] In the embodiment, the atomizer support 100 is distributed along the axial direction of the atomizer device with the electrode support 210, and the atomizer support 100 is rotationally connected with the electrode support 210. Specifically, the main shell 400 includes an upper shell 410 and a lower shell 420, the upper shell 410 is sleeved outside the atomizer support 100 and is fixedly connected with the atomizer support 100, the lower shell 420 is sleeved outside the electrode support 210, the lower shell 420 is clamped with the electrode support 210, and the bottom of the atomizer support 100 is rotationally sleeved with the lower shell 420, so that the rotation connection between the atomizer support 100 and the electrode support 210 is formed through the lower shell 420. That is, the power assembly 200 is rotationally connected with the atomizer support 100 as a whole.

[0114] In the embodiment, referring to FIG. 12, the side of the atomizer support 100 away from the electrode support 210 is provided with a suction nozzle 310, the suction nozzle 310 is in axial synchronous sliding connection with the atomizer support 100 along the axial direction of the atomizer, and the suction nozzle 310 is in synchronous rotation connection with the electrode support 210. In the embodiment, the suction nozzle 310 is in synchronous rotation connection with the electrode support 210, that is, the suction nozzle 310 and the electrode support 210 do not rotate relative to each other, so when the atomizer support 100 rotates relative to the electrode support 210, the suction nozzle 310 does not rotate with the atomizer support 100, and the suction nozzle 310 and the electrode support 210 keep corresponding in the circumferential direction. In this way, when the atomizer 2 needs to be replaced in the use state, the atomizer 2 in the use state can be connected to the suction nozzle 310 by rotating the atomizer 2 to the right position, without the need to rotate the suction nozzle 310 to connect the suction nozzle 310 to the atomizer 2 after the atomizer 2 is rotated to the right position, thereby reducing the operation difficulty. In addition, the suction nozzle 310 is in axial synchronous sliding connection with the atomizer support 100, so that the suction nozzle 310 moves axially when the atomizer support 100 rotates and moves axially, which avoids the structural interference between the atomizer support 100 and the suction nozzle 310, and also avoids the need to connect the atomizer support 100 to the suction nozzle 310 axially after the atomizer support 100 is rotated, thereby reducing the operation difficulty.

[0115] In the embodiment, referring to FIG. 12, the suction nozzle 310 is provided with a first air outlet 311, and the suction nozzle sealing member 320 is provided with a second connecting port 321. When the atomizer support 100 rotates with the atomizers 2, the second connecting ports 321 are sequentially connected to the second air outlets 22 of the atomizers 2, so as to realize the switching of the atomizers 2. In the embodiment, the atomizers 2 can be switched by rotating the atomizer support 100, and the electrical connection, air inlet and air outlet of the atomizers 2 can be switched synchronously.

[0116] In the embodiment, referring to FIG. 13, the suction nozzle 310 is provided with a connecting rod 312, the connecting rod 312 is arranged through the center of the atomizer support 100, the connecting rod 312 is provided with a plug-in part 313, the electrode support 210 is provided with a first insertion slot 215, and the plug-in part 313 is arranged through the first insertion slot 215 to form the synchronous rotation connection between the suction nozzle 310 and the electrode support 210. The side of the plug-in part 313 away from the suction nozzle 310 is provided with a stop part 314, the stop part 314 is stopped at the side of the first insertion slot 215 away from the suction nozzle 310, and the movement stroke of the stop part 314 along the axial direction of the atomizer support 100 is greater than or equal to the axial sliding stroke of the atomizer support 100.

[0117] It should be noted that the face of the first slot 215 away from the side of the suction nozzle 310 is a stop face, and when the entire aerosol generating device is in a working state, the distance between the stop portion 314 and the stop face is the travel of the stop portion 314. When the suction nozzle 310 moves with the atomizer support 100, the stop portion 314 can move within the travel, and when the suction nozzle 310 moves away from the electrode support 210 by the travel, the stop portion 314 abuts against the stop face, thereby preventing the suction nozzle 310 from being separated from the electrode support 210.

[0118] In the present embodiment, referring to FIG. 13, a reset assembly 700 is arranged between the suction nozzle 310 and the electrode support 210, and the reset assembly 700 is used to reset the suction nozzle 310 after the suction nozzle 310 moves away from the electrode support 210 by a preset distance along with the atomizer support 100.

[0119] Specifically, referring to FIG. 13, the reset assembly 700 includes a second elastic member 710, a first mounting column 720, a first locking member 730, a second mounting column 740, and a second locking member 750. The second elastic member 710 is a cylindrical spring, the first mounting column 720 is mounted on the suction nozzle 310 through the first locking member 730, the second mounting column 740 is mounted on the electrode support 210 through the second locking member 750, and the cylindrical spring is sleeved on the first mounting column 720 and the second mounting column 740 respectively and is fixedly connected with the suction nozzle 310 and the electrode support 210 respectively. The first mounting column 720 and the second mounting column 740 are arranged such that one end of the second elastic member 710 is connected with the suction nozzle 310 and the other end of the second elastic member 710 is connected with the electrode support 210, and the suction nozzle 310 is reset by the pulling force of the second elastic member 710. The extension and contraction of the cylindrical spring can be guided to ensure that the suction nozzle 310 is reset stably. It can be understood that in other embodiments, the first mounting column 720 can be connected to the suction nozzle 310 only, or the second mounting column 740 can be connected to the electrode support 210 only. In addition, in other embodiments, the second elastic member 710 can also be a spring sheet, a spring cord or other elastic objects. In addition, the reset assembly 700 can also be a magnetic assembly, which is not limited here.

[0120] In the present embodiment, referring to FIG. 12, the atomizer 2 abuts between the suction nozzle seal 320 and the atomizer support 100 along the axial direction of the atomizer, so that when the atomizer support 100 rises away from the electrode support 210, the suction nozzle seal 320 and the suction nozzle 310 can rise together. At the same time, since the reset assembly 700 is connected between the suction nozzle 310 and the electrode support 210, when the reset assembly 700 drives the suction nozzle 310 to reset axially, the atomizer support 100 can be driven to reset axially, and thus the atomizer support 100 and the suction nozzle 310 are connected synchronously along the axial direction of the atomizer.

[0121] Embodiment Five:

[0122] The technical features of the atomization device in this embodiment are basically the same as those in the atomization device in Embodiment 1, and the difference is that, in this embodiment, referring to FIG. 14, the atomization device further comprises a suction nozzle 310, which is synchronously rotatably connected with the electrode support 210. In this way, when the electrode support 210 rotates relative to the atomizer support 100, the electrical connection, air inlet and air outlet states of the atomizers 2 can be switched at the same time.

[0123] It should be noted that the synchronous rotation connection between the suction nozzle 310 and the electrode support 210 means that the relative rotation between the suction nozzle 310 and the electrode support 210 is limited. The synchronous rotation connection between the suction nozzle 310 and the electrode support 210 can be formed by limiting the cooperation structure between the suction nozzle 310 and the electrode support 210, or the suction nozzle 310 and the electrode support 210 can be directly fixedly connected, integrally connected or detachably connected by clamping, etc., which can ensure that the suction nozzle 310 and the electrode support 210 can rotate synchronously.

Rotating the suction nozzle 310 can drive the electrode support 210 to rotate relative to the atomizer support 100, so as to synchronously switch the electrical connection, air inlet and air outlet states of each atomizer 2.

[0144] Wherein, since the main shell 400 is an integral connection structure, the main shell 400 of the atomization device can be complete in the axial direction, and the product appearance is more beautiful without a split line. At the same time, since the main shell 400 is an integral connection structure, and since the suction nozzle 310 is located at the top of the entire atomization device, only the suction nozzle 310 needs to be rotated at the top of the atomization device when the state is switched.

[0145] Please refer to FIG. 18 and FIG. 19, the rotating shaft 800 is formed at the center of the electrode holder 210 side towards the atomizer holder 100, the atomizer holder 100 is sleeved on the rotating shaft 800, the shaft hole 810 is formed on the atomizer holder 100, and the electrode holder 210 and the atomizer holder 100 are rotationally connected through the rotating shaft 800 and the shaft hole 810.

[0146] In this embodiment, please refer to FIG. 18, the first end of the rotating shaft 800 is integrally connected with the electrode holder 210, and the second end of the rotating shaft 800 is synchronously rotationally connected with the suction nozzle 310 through the concave-convex clamping.

The second installation cavity 470 is used for installing the power supply assembly 200 and the control unit 600.

[0148] In this embodiment, please refer to FIG. 19 and FIG. 20, the first matching surface 181 can be arranged on the end surface of the atomizer holder 100 towards the electrode holder 210, and the second matching surface 201 can be arranged on the end surface of the electrode holder 210 towards the atomizer holder 100. Specifically, the end surface of the atomizer holder 100 towards the electrode holder 210 is formed with a guide groove 202, and the surface of the guide groove 202 towards the electrode holder 210 is the first matching surface 181; the end surface of the electrode holder 210 towards the atomizer holder 100 is provided with a guide protrusion 180, the surface of the guide protrusion 180 towards the atomizer holder 100 is the high surface 2015, the end surface of the electrode holder 210 towards the atomizer holder 100 is the low surface 2014, and the circumferential two sides of the guide protrusion 180 are respectively the uphill section 2016 and the downhill section 2017.

[0149] Specifically, the side of the atomizer support 100 facing the electrode support 210 is formed with a plurality of circumferentially spaced guide grooves 202, and the side of the electrode support 210 facing the atomizer support 100 is formed with a plurality of circumferentially spaced guide protrusions 180. At the beginning of the rotation of the atomizer support 100, the guide protrusion 180 slides out of one of the guide grooves 202 and abuts against the end face of the atomizer support 100. At the end of the rotation of the atomizer support 100, the guide protrusion 180 is clamped into another guide groove 202. The above design not only reduces the friction of the electrode 220, but also facilitates the user to understand the angle of rotation of the atomizer support 100 and increases the user's playability, because the alternating clamping of the guide protrusion 180 and the guide groove 202 will cause a jam during the rotation.

[0150] In this embodiment, referring to FIGS. 19 and 20, each guide groove 202 is formed at the center of the side of the atomizer support 100 facing the electrode support 210, and each guide protrusion 180 is formed at the center of the side of the electrode support 210 facing the atomizer support 100.

[0152] Specifically, referring to FIG. 21, the two circles of conductive rings 214 are respectively formed on the side of the electrode support 210 facing the main housing 400.

[0153] Specifically, referring to FIG. 21, the two conductive rings 214 respectively extend toward the two electrodes 220 with extension sections 2141, and the outer peripheral wall of the electrode 220 is arranged in abutment with the extension section 2141 to form the electrical connection between the conductive ring 214 and the electrode 220.

[0154] Alternatively, the conductive material is laid on the electrode support 210 to form the conductive ring 214.

[0157] Among them, the number of second air inlets 211 can be one or more, but the number of second air inlets 211 is less than the number of atomizers 2. When the number of second air inlets 211 is one, in the same working state, the second air inlet 211 is communicated with the first air inlet 21 of one of the atomizers 2, so that the atomizer 2 is communicated with the external atmosphere. When the number of second air inlets 211 is more, in the same working state, the plurality of second air inlets 211 can be respectively communicated with the first air inlets 21 of part of the atomizers 2, so that part of the atomizers 2 are connected to the external atmosphere, and part of the atomizers 2 work.

[0162] In one embodiment, referring to FIG. 18, since the main housing 400 is a one-piece structure, and the suction nozzle 310 is located at the top of the entire atomization device, when the state switching is performed, the state switching of each atomizer 2 can be achieved by rotating the suction nozzle 310 at the top of the atomization device.

At the same time, since the main housing 400 is a one-piece structure, and the bottom cover 500 is located at the bottom of the entire atomization device, when the state switching is performed, only the bottom cover 500 needs to be rotated at the bottom of the atomization device.

The partition holder 160 is radially distributed from the center of the support plate 140 by a plurality of baffles, and the partition holder 160 is used for separating each atomizer 2. The sleeve 150 is sleeved on the outside of the electrode holder 210, and the sleeve 150 is used for sleeving and clamping with the lower half of the main shell 400.

The above arrangement allows the atomizers 2 in the atomizer support 100 to be arranged in a straight line, thereby reducing the thickness of the atomization device and facilitating the construction of a box-shaped aerosol production device. Compared with the design of arranging the atomizers 2 in a circular array, this design is more conducive to reducing the size of the device and facilitating portability.

[0209] In this embodiment, the transmission mechanism 1900 is a belt transmission mechanism, which includes a driving member 1910, a driving wheel 1920, a driven wheel 1930, and a belt 1940. The driving wheel 1920 is connected to the driving member 1910, the driving wheel 1920 and the driven wheel 1930 are arranged in a direction along the arrangement of the atomizers 2, the belt 1940 is wound around the driving wheel 1920, and the electrode support 210 is mounted on the belt 1940. The driving member 1910 drives the driving wheel 1920 to rotate, thereby driving the driven wheel 1930 to rotate, driving the belt 1940 to move, and further driving the electrode support 210 to move linearly to form electrical connection and air communication with each atomizer 2 in turn. The belt transmission mechanism occupies less space overall and in the direction along the arrangement of the atomizers 2, thereby facilitating the miniaturization design of the atomization device. It can be understood that in other embodiments, the movement of the electrode support 210 can also be achieved by gear and rack, ball screw, screw, etc., which is not limited here.

When the electrode support 210 is moved to the position, the guide protrusion 180 is engaged with the guide groove 202. When the electrode support 210 starts to move, the guide protrusion 180 slides out along the guide groove 202, and the guide protrusion 180 abuts against the end face of the atomizer support 100, so that the atomizer support 100 is lifted, and the atomizers 2 are also lifted.

[0216] In this embodiment, referring to FIG. 34, the electrode holder 210 is provided with a first magnetic member 230. When the guide protrusion 180 and the guide groove 202 are matched, the first magnetic member 230 adsorbs the atomizer 2, so as to increase the contact force between the electrode 220 and the electrode contact 231, and ensure the stable electrical connection.

[0220] Embodiment Eleven

[0221] The technical features of the atomization device in this embodiment are basically the same as those in the atomization device in Embodiment One, with the exception that, in this embodiment, referring to FIGS. 36-38, the power supply assembly 200 includes an electrode holder 210, which is provided with multiple groups of electrodes 220 and multiple second air inlets 211, each electrode 220 is electrically connected to each atomizer 2, and each second air inlet 211 is in communication with each first air inlet 21; the atomization device further includes an air passage switch 2200, a circuit board 610, and a circuit switch 2300; the air passage switch 2200 is movable relative to the atomizer holder 100 to open or close each second air inlet 211; the circuit switch 2300 is movable relative to the atomizer holder 100 to electrically connect or disconnect each electrode 220 from the circuit board 610; and the air passage switch 2200 and the circuit switch 2300 are linked together. In other words, part of the power supply assembly 200 is movable relative to the atomizer holder 100 to switch the use state of at least one atomizer 2.

[0222] It should be noted that the air passage switch 2200 is movable to open or close each second air inlet 211, and the open or closed state of each second air inlet 211 can be different. Specifically, the air passage switch 2200 can open one or some of the second air inlets 211 and close the other second air inlets 211, or the air passage switch 2200 can close all the second air inlets 211.

[0223] Similarly, the circuit switch 2300 can electrically connect one or some of the electrodes 220 to the circuit board 610 and disconnect the other electrodes 220 from the circuit board 610, or disconnect each electrode 220 from the circuit board 610.

[0224] In general, in this embodiment, since the air passage switch 2200 and the circuit switch 2300 are linked together, only the air passage switch 2200 or the circuit switch 2300 needs to be moved to switch the state of each electrode 220 and each second air inlet 211, which is simple to operate.

The first ends of the independent airways 2410 are in communication with the second air inlets 211. The airway switch 2200 is slidably arranged on the end surface of the connecting seat 2400 corresponding to the second ends of the independent airways 2410. When the airway switch 2200 is slid to any gear, the fourth air inlet 2210 is in communication with the second end of one of the independent airways 2410, and the airway switch 2200 covers the second ends of the remaining independent airways 2410, thereby realizing the communication between one of the atomizers 2 and the external atmosphere.

[0231] Specifically, the second ends of the independent airways 2410 are arranged in a straight line at equal intervals or unequal intervals, so that the airway switch 2200 is in communication with different independent airways 2410 when it is slid. In other embodiments, the second ends of the independent airways 2410 can also be arranged in a circular shape, and the airway switch 2200 can be rotated to switch the air inlets.

[0242] Embodiment Twelve:

[0243] The technical features of the atomization device in this embodiment are basically the same as those in Embodiment One, with the exception that the inner wall of the atomizer support 100 is provided with a sliding block 101, and the outer wall of the electrode support 210 is provided with a matching groove 203, with the sliding block 101 slidingly arranged in the matching groove 203; the first matching surface 181 is the surface of the sliding block 101 supported on the inner wall of the matching groove 203 along the axial direction of the atomization device, and the second matching surface 201 is the inner wall surface of the matching groove 203 for supporting the sliding block 101.

[0244] Specifically, the specific positions of the first matching surface 181 and the second matching surface 201 are shown in FIG. 41.

[0245] In the initial stage of rotation of the atomizer support 100, the sliding block 101 is located at the low position surface 2014, at which time the electrode 220 is in contact with the electrical connection column 23 of one of the atomizers 2 to achieve electrical connection. Then, during the rotation process, the sliding block 101 moves from the low position surface 2014 to the highest position surface 2018, and the electrode 220 is separated from the electrical connection column 23, and a gap gradually appears between the electrode support 210 and the atomizer support 100 along the axial direction of the electrode support 210, so as to avoid abrasion of the electrode 220. When the sliding block 101 slides to the adjacent highest position surface 2018, the sliding block 101 rises by a preset distance along the axial direction of the electrode support 210, thereby driving the atomizer support 100 to rise by a preset distance away from the electrode support 210, so as to reduce or avoid friction between the atomizer support 100 and the electrode 220, avoid interference between the atomizer support 100 and the electrode support 210 due to planar friction, and ensure smooth rotation between the atomizer support 100 and the electrode support 210. Subsequently, during the continuous rotation process, the sliding block 101 moves from the highest position surface 2018 to the next low position surface 2014, and the gap between the electrode support 210 and the atomizer support 100 along the axial direction of the electrode support 210 gradually decreases. At the end of the rotation, the sliding block 101 is located at the next low position surface 2014, at which time the electrode 220 is in contact with the electrical connection column 23 of the other atomizer 2 to achieve electrical connection. It can be understood that in other embodiments of the present application, the matching groove 203 can also be formed on the inner wall of the atomizer support 100, and the sliding block 101 is formed on the outer wall of the electrode support 210, which is not limited herein.

[0246] In one embodiment, referring to FIG. 41 and FIG. 44, the matching groove 203 further has a third matching surface 2031 oppositely spaced from the second matching surface 201, the third matching surface 2031 corresponding to the low position surface 2014 has a first limiting surface 2032, and the low position surface 2014 and the first limiting surface 2032 are both planar. The slider 101 further has a fourth matching surface 1013 oppositely spaced from the first matching surface 181, and the first matching surface 181 and the fourth matching surface 1013 are both planar. In this way, when the slider 101 slides to the low position surface 2014, the slider 101 can be axially limited between the low position surface 2014 and the first limiting surface 2032, thereby ensuring the stability of the electrical connection between the atomizer 2 and the electrode 220.

[0247] In one embodiment, referring to FIG. 41, the third matching surface 2031 corresponding to the highest surface 2018 further has a second limiting surface 2033, and the highest surface 2018 and the second limiting surface 2033 are both planar. In this way, the slider 101 can stably slide on the highest surface 2018 during rotation, thereby ensuring the stability of the rotation of the atomizer holder 100.

[0248] Optionally, the uphill section 2016 can extend in a straight line or in a curve.

[0249] Optionally, the downhill section 2017 can extend in a straight line or in a curve.

[0250] In one embodiment, the number of the high position surfaces 2015 is the same as the number of the atomizers 2. In this way, when the slider 101 slides out of one low position surface 2014 and slides into another low position surface 2014, it corresponds to a rotation of the atomizer holder 100 by a preset angle, realizing the replacement of one atomizer 2, which is convenient for the user to rotate and control. It can be understood that in other embodiments of the present application, the number of the high position surfaces 2015 can also be different from the number of the atomizers 2. For example, the number of the atomizers 2 is an integer multiple of the number of the high position surfaces 2015. In this way, when the slider 101 slides out of one low position surface 2014 and slides into another low position surface 2014, it realizes the replacement of two atomizers 2 together.

[0251] In the above embodiment, by sliding the slider 101 in the matching groove 203 in the circumferential direction, the atomizer holder 100 is realized to move closer to or away from the electrode 220 along the axial direction of the atomizer. In addition, when the slider 101 is clamped into the matching groove 203, the atomizer holder 100 and the electrode holder 210 are limited along the axial direction of the atomizer, thereby ensuring that the atomizer holder 100 and the electrode holder 210 slide relatively along the axial direction while rotating relatively, but are difficult to separate, thereby ensuring the stability of the rotation of the atomizer holder 100 and the electrode holder 210.

[0252] Specifically, during the sliding process, the first fitting surface 181 and the fourth fitting surface 1013 of the sliding block 101 respectively abut against the second fitting surface 201 and the third fitting surface 2031 of the fitting groove 203, so as to form the axial limiting between the atomizer support 100 and the electrode support 210.

[0253] In the above embodiment, referring to FIG. 44, the outer peripheral wall of the electrode support 210 is provided with a first protruding ring 2192 and a second protruding ring 2193, the first protruding ring 2192 and the second protruding ring 2193 are spaced apart along the axial direction of the atomizer to form the fitting groove 203, and the sliding block 101 is clamped between the first protruding ring 2192 and the second protruding ring 2193 from the side of the first protruding ring 2192 away from the second protruding ring 2193. Specifically, the sliding block 101 is clamped into the fitting groove 203 by overcoming the elasticity of the sliding block 101 and the first protruding ring 2192 through an external force, so that the sliding block 101 can slide in the fitting groove 203.

[0254] Specifically, referring to FIG. 44, the sliding block 101 includes a connecting surface 1011 and a first guide surface 1012, the connecting surface 1011 is arranged opposite to the inner peripheral surface of the atomizer support 100, one end of the connecting surface 1011 is connected to the fourth fitting surface 1013, the first guide surface 1012 is connected between the other end of the connecting surface 1011 and the first fitting surface 181, and the first guide surface 1012 is arranged obliquely relative to the first fitting surface 181. The surface of the first protruding ring 2192 away from the second protruding ring 2193 is a second guide surface 2194, and the second guide surface 2194 is arranged obliquely relative to the axial direction of the atomizer. When the sliding block 101 abuts against the first protruding ring 2192, the first guide surface 1012 is arranged in abutment with the second guide surface 2194, and the sliding block 101 can be quickly clamped into the fitting groove 203 from the first protruding ring 2192 through the guiding action of the first guide surface 1012 and the second guide surface 2194.

[0255] Optionally, the sliding block 101 can be substantially square-shaped and provided with the first guide surface 1012. It can be understood that in other embodiments of the present application, the surface of the sliding block 101 can also be curved, for example, the first fitting surface 181 and the fourth fitting surface 1013 can be curved.

[0256] In one embodiment, referring to FIG. 43, the electrode support 210 extends a sleeving portion 204 from the side edge thereof toward the atomizer support 100, and the atomizer support 100 is sleeved outside the sleeving portion 204 to form a rotational connection between the atomizer support 100 and the electrode support 210. The fitting groove 203 is formed on the outer peripheral wall of the sleeving portion 204.

[0257] In the present application, the atomizer 2 and the electrode 220 are electrically connected by rotating the atomizer support 100 relative to the electrode support 210. In order to facilitate the user to know whether the atomizer support 100 or the electrode support 210 is rotated to the position in time when rotating the atomizer support 100 or the electrode support 210, the following scheme is designed in the embodiment.

[0258] Specifically, referring to FIGS. 42 and 43, the inner wall of the atomizer support 100 is provided with a protrusion 102, and the outer wall of the electrode support 210 is provided with a plurality of matching grooves 205 arranged along the circumference. During the relative rotation of the atomizer support 100 and the electrode support 210, the protrusion 102 is clamped in different matching grooves 205. Specifically, when the atomizer support 100 rotates relative to the electrode support 210, the protrusion 102 is separated from one of the matching grooves 205, and after the atomizer support 100 is rotated to the position, the protrusion 102 is clamped in the next matching groove 205, thereby ensuring that the atomizer support 100 after rotation to the position is assembled stably and cannot be rotated by mistake. At the same time, the clamping between the protrusion 102 and the matching groove 205 can cause a jam, thereby prompting the user.

[0259] The number of the matching grooves 205 can be the same as the number of the atomizers 2, so that when the atomizer support 100 is rotated by a predetermined angle, the protrusion 102 is clamped in the next matching groove 205 from one of the matching grooves 205. This not only forms a circumferential limit, but also causes a jam every time the rotation is to the position, thereby prompting the user to rotate to the position. Of course, in other embodiments, the number of the matching grooves 205 can be N times the number of the atomizers 2, that is, the protrusion 102 is clamped in the next matching groove 205 after every N times of jamming.

[0260] The number of the protrusions 102 can be one, and the protrusion 102 is clamped with one of the matching grooves 205. Alternatively, the number of the protrusions 102 can be multiple, and it is necessary to ensure that the number of the matching grooves 205 is an integer multiple of the number of the protrusions 102, so that each protrusion 102 can be clamped in the corresponding matching groove 205.

[0261] In the above embodiment, the protrusion 102 extends along the axial direction of the electrode support 210, and the matching groove 205 is arranged through the first protruding ring 2192 along the axial direction of the atomizer. When the slider 101 is clamped in the matching groove 203 along the axial direction of the atomizer, the protrusion 102 is inserted into the matching groove 205. The arrangement of the protrusion 102 can improve the clamping stability and strength between the protrusion 102 and the matching groove 205. It can be understood that in other embodiments of the present application, the protrusion 102 can not be in a strip shape, but in a block shape or an arc shape, and the matching groove 205 can be a guide groove or an arc groove. In addition, the matching groove 205 can be formed on the atomizer support 100, and the protrusion 102 can be formed on the electrode support 210, which is not limited here.

[0262] In addition, since the atomizer support 100 and the electrode support 210 are rotated while moving axially towards or away from each other, and the atomizer 2 is detachably assembled in the atomizer support 100, in order to ensure the stability of the electrical connection between the atomizer 2 and the electrode 220. In one embodiment, referring to FIGS. 42 and 43, a first magnetic member 230 is installed on the electrode support 210, and a second magnetic member 25 is arranged in the atomizer 2, the first magnetic member 230 and the second magnetic member 25 are attracted to each other, thereby being able to attract the atomizer 2 that is rotated into position each time, to ensure the stability of the electrical connection between the electrode 220 and the atomizer 2.

[0263] Alternatively, a first magnetic member 230 is arranged at the center of the electrode support 210, and when each atomizer 2 is assembled in the atomizer support 100, a second magnetic member 25 is arranged around the periphery of the first magnetic member 230 to be attracted to the first magnetic member 230, respectively. In other embodiments, the first magnetic member 230 can also be arranged on the electrode support 210 on both sides of the two electrodes 220, or a first magnetic member 230 can also be arranged corresponding to each atomizer 2.

[0264] On the other hand, the embodiments of the present application also provide an aerosol generating device, comprising a plurality of atomizers 2 and the above-mentioned atomizer assembly, and at least one atomizer 2 is accommodated in the atomizer support 100. The aerosol generating device can carry a plurality of atomizers 2 and different flavors of atomizers 2 through the arrangement of the above-mentioned atomizer assembly, thereby being able to meet the needs of different users for large suction and multi-flavor requirements. When in use, one or more atomizers 2 can be arranged in the atomizer assembly.

[0265] The above is only an optional embodiment of the present application and is not intended to limit the present application. The present application can have various changes and modifications for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
