Embodiment 1

Referring to FIGS. 1 to 3, the power supply assembly 200 comprises an electrode holder 210 and at least one electrode 220 disposed on the electrode holder 210. The relative position of the electrode holder 210 and the atomizer holder 100 is variable, to synchronously switch the electrical connection state of the electrode 220 with the at least one atomizer 2 and the air communication state of the first air inlet 21 with the external air. In this embodiment, the state switching of at least one atomizer 2 is achieved by the relative motion between the electrode holder 210 in the power supply assembly 200 and the atomizer holder 100. Structures of the power supply assembly 200 other than the electrode holder 210 and the electrode 220, such as the battery 280, may be fixed relative to the electrode holder 210. That is, the entire power supply assembly 200 and the atomizer holder 100 perform the relative motion. Structures of the power supply assembly 200 other than the electrode holder 210 and the electrode 220, such as the battery 280, may move relative to the electrode holder 210. That is, a part of the power supply assembly 200 and the atomizer holder 100 perform the relative motion.
In the present embodiment, the electrode holder 210 and the atomizer holder 100 are rotatable relative to each other to synchronously switch the electrical connection state between the electrode 220 and any of the plurality of atomizers 2 and the air communication state between the first air inlet 21 and the external air.
Specifically, referring to FIGS. 1 and 2, the power supply assembly 200 further comprises a battery 280 and a primary housing 400. The battery 280 is fixedly mounted on the electrode holder 210, and the primary housing 400 is mounted around the electrode holder 210. The primary housing 400 is attached to electrode holder 210 by snap fit, and the primary housing 400 abuts against the atomizer holder 100 in the axial direction of the atomizing device. The atomizer holder 100 or the primary housing 400 may be rotated to cause the atomizer holder 100 and the entire power supply assembly 200 to rotate relative to each other, thereby switching a use state of the at least one atomizer 2.
In this embodiment, referring to FIGS. 1 to 3, the atomizing device further comprises a rotating shaft 800 connected to the atomizer holder 100. A shaft hole 810 is formed in the electrode holder 210, and the rotating shaft 800 is rotatably inserted into the shaft hole 810 to form a rotatable connection between the atomizer holder 100 and the electrode holder 210. In order to allow the state switching, it is only necessary to manually rotate the atomizer holder 100 or the electrode holder 210.
In this embodiment, the rotating shaft 800 is located at a center of the electrode holder 210. It will be appreciated that, in other embodiments, the rotating shaft 800 may also be disposed eccentrically. In another example, the atomizing device may not have the rotating shaft, and for example, the electrode holder 210 may act as the rotating shaft around which the atomizer holder 100 rotates, or the atomizer holder 100 may act as the rotating shaft around which the electrode holder 210 rotates.
In this embodiment, the rotating shaft 800 is made in one piece with the atomizer holder 100. In other embodiments, the rotating shaft 800 may also be connected to the atomizer holder by screw locking, interference fit, adhesive bonding, or welding.
In the present application, in order to ensure a good connection between the electrode 220 and the atomizer 2, the electrode 220 is generally designed to extend slightly beyond a contact plane, i.e. the surface of the electrode holder 210 facing towards the atomizer holder 100. However, during the relative rotation of the atomizer holder 100 and the electrode holder 210, the electrode 220 continuously rubs against the end face of the atomizer holder 100, resulting in a serious rotational friction and poor user experience. The friction will also cause the atomizing device to wear, and the scraping of the electrode 220 will easily wear off the gold plating layer thereon, resulting in an increase in contact resistance, affecting the heating and atomizing performance, and also affecting the service life of the elastic pin.
In order to improve the frictional state of the electrode 220 on the electrode holder 210, the electrode 220 is preferably a compressible electrode which may be an elastic pin or an elastic tongue.
In the present application, the atomizer holder 100 is capable of avoiding the electrode 220 during its rotation relative to the electrode holder 210. Specifically, the atomizer holder 100 can be rotated from a first orientation to a second orientation and then to a third orientation relative to the electrode 220. When the atomizer holder 100 is in the first orientation relative to the electrode 220, at least one first atomizer of the plurality of atomizers 2 is electrically connected to the electrode 220. When the atomizer holder 100 is in the second orientation relative to the electrode 220, the atomizer holder 100 avoids the electrode 220. When the atomizer holder 100 is in the third orientation relative to the electrode 220, at least one second atomizer of the plurality of atomizers 2 is electrically connected to the electrode 220. In the case where a set of electrodes 220 is provided on the electrode holder 210, the atomizer electrically connected to the electrodes 220 is switched from one atomizer to another atomizer 2 adjacent to said one atomizer when the atomizer holder 100 rotates from the first orientation to the third orientation relative to the electrode 220. In the case where two or more sets of electrodes 220 are provided on the electrode holder 210, when the atomizer holder 100 rotates from the first orientation to the third orientation relative to the electrodes 220, the atomizer electrically connected to the electrode 220 is switched from one atomizer to another atomizer 2 separated from said one atomizer 2 by one or more atomizers.
The avoidance of the atomizer holder 100 from the electrode 220 may be implemented in following ways: the atomizer holder 100 and the electrode holder 210 rotate relative to each other while sliding axially relative to each other in an axial direction of the atomizing device to allow the atomizer holder 100 to avoid the electrode 220, or an avoidance groove may be formed on the atomizer holder 100 at a position corresponding to the movement trajectory of the electrode 220, to avoid the electrode 220.
When the atomizer holder 100 rotates from the first orientation to the third orientation relative to the electrode 220, the atomizer holder 100 just rotates by a predetermined angle, that is, the electrical connection state of atomizers 2 is switched once, specifically, the electrical connection of the electrode 220 to the one atomizer 2 is switched to the electrical connection of the electrode 220 to another atomizer 2. Further, when the atomizer holder 100 is in the second orientation relative to the electrode 220, the atomizer holder 100 and the electrode holder 210 are in a state of relative movement with respect to each other, and the electrode 220 is not electrically connected to the atomizer 2.
In the present application, when the atomizer holder 100 is in the first orientation and the third orientation with respect to the electrode 220, the electrode 220 can be electrically connected to at least one first atomizer of the plurality of atomizers 2. When the atomizer holder is in the second orientation with respect to the electrode 220, the atomizer holder 100 avoids the electrode 220. During the relative rotation of the atomizer holder 100 and the electrode holder 210, the electrode 220 does not interfere with the atomizer holder 100, thereby reducing wear of the electrode 220.
One manner in which the atomizer holder 100 avoids the electrode 220 will be described in detail. Specifically, the atomizer holder 100 and the electrode holder 210 rotate while sliding relative to each other in the axial direction of the atomizing device so that the atomizer holder 100 may avoid the electrode 220. In this way, the user only needs to perform a rotation operation to cause the atomizer holder 100 and the electrode holder 210 to slide away from each other during the rotation so that the atomizer holder 100 may avoid the electrode 220. Therefore, the friction between the electrode 220 and the atomizer holder 100 can be reduced or even avoided, the wear of the gold plating layer of the counter electrode 220 can be reduced, the heating atomization performance of the atomizer 2 can be improved, and the service life of the electrode 220 can also be improved. In addition, there is no need to pull out the atomizer holder 100 with one hand, and then rotate the atomizer holder 100 with the other hand, which improves the convenience of using the aerosol generating device and improves the user experience.
Specifically, referring to FIG. 4, the atomizer holder 100 has a first cooperating face 181, and the electrode holder 210 has a second cooperating face 201 that slidably cooperates with the first cooperating face 181. The first cooperating face 181 and the second cooperating face 201 are disposed opposite to each other one in the axial direction of the atomizing device. The second cooperating face 201 has a first position 2011, a second position 2012, and a third position 2013. When the first cooperating face 181 is located at the first position 2011, the atomizer holder 100 is in the first orientation with respect to the electrode 220, when the first cooperating face 181 is located at the second position 2012, the atomizer holder 100 is in the second orientation with respect to the electrode 220, and when the first cooperating face 181 is located at the third position 2013, the atomizer holder 100 is in the third orientation with respect to the electrode 220.
The first position 2011, the second position 2012, and the third position 2013 are positions at which the second cooperating face 201 corresponds to the rotation of the atomizer holder 100 from the first orientation to the third orientation with respect to the electrode 220. The first position 2011, the second position 2012, and the third position 2013 are sequentially distributed along the circumferential direction of the atomizing device. During the rotation of the atomizer holder 100 relative to the electrode holder 210 by a preset angle, the first cooperating face 181 slides from the first position 2011 of the second cooperating face 201 to the second position 2012, and then slides from the second position 2012 to the third position 2013. By changing the cooperating position of the first cooperating face 181 and the second cooperating face 201, the electrode holder 210 and the atomizer holder 100 move towards or away from each other in the axial direction of the atomizing device, thereby avoiding the electrode 220. Of course, in other embodiments, the second cooperating face 201 may be formed on the atomizer holder 100, and the first cooperating face 181 may be formed on the electrode holder 210.
In this embodiment, referring to FIG. 4, the second cooperating face 201 has a plurality of trough faces 2014 arranged along the circumferential direction at intervals, and a peak face 2015 is connected between each two adjacent trough faces 2014. When the first cooperating face 181 cooperates with the trough face 2014, the atomizer holder 100 is in the first or third orientation with respect to the electrode 220. When the first cooperating face 181 cooperates with the peak face 2015, the atomizer holder 100 is in the second orientation with respect to the electrode 220.
It should be noted that, during the rotation of the atomizer holder 100 from the first orientation through the second orientation to the third orientation relative to the electrode 220, the first cooperating face 181 slides from one trough face 2014 of the second cooperating face 201 to a peak face 2015 and then to a next trough face 2014. Said one trough face 2014 is the first position 2011 of the second cooperating face 201, the next trough face 2014 is the third position 2013 of the second cooperating face 201, and said one peak face 2015 is the second position 2012 of the second cooperating face 201. That is, one trough face 2014, one peak face 2015 and one trough face 2014 connected in sequence exactly correspond to the first position 2011, the second position 2012, and the third position 2013.
In this embodiment, trough faces 2014 and peak faces 2015 are provided. When the first cooperating face 181 slides to the trough face 2014, the atomizer holder 100 abuts against the electrode holder 210 in the axial direction of the atomizing device so that the atomizer 2 abuts against the electrode 220 to form an electrical connection between the atomizer and the electrode. When the first cooperating face 181 slides to the peak face 2015, the atomizer holder 100 and the electrode holder 210 slide relative to each other in the axial direction of the atomizing device so that the atomizer holder 100 avoids the electrode 220.
In this embodiment, referring to FIG. 4, the peak face 2015 is trapezoidal. Specifically, the peak face 2015 comprises an uphill section 2016, a downhill section 2017, and a top surface 2018. The top surface 2018 is the portion of peak face 2015 that attains the maximum distance from the trough face 2014. The uphill section 2016 is connected between one trough face 2014 and the top surface 2018, and a downhill section 2017 is connected between the top surface 2018 and the next trough face 2014. The top surface 2018 is planar. It can be understood that, in other embodiments of the present application, the peak face 2015 may also be triangular, or the peak face 2015 may also be curved or wavy, and the present invention is not limited thereto.
In this embodiment, referring to FIGS. 2 and 4, the first cooperating face 181 is disposed on the end face of the atomizer holder 100 facing towards the electrode holder 210. In this case, a guide protrusion 180 may be formed on the atomizer holder 100, and the first cooperating face 181 is the face of the guide protrusion 180 facing towards the electrode holder 210. Correspondingly, the second cooperating face 201 may be disposed on the end face of the electrode holder 210 facing towards the atomizer holder 100. A plurality of guide grooves 202 arranged at intervals along the circumferential direction may be formed in the electrode holder 210. The bottom face of the guide groove 202 is the trough face 2014, the two side faces of the guide groove 202 along the circumferential direction are the uphill section 2016 and the downhill section 2017 respectively, and the end face of the electrode holder 210 is the top surface 2018. When the guide protrusion 180 slides into the guide groove 202, the end face of the atomizer holder 100 abuts against the top surface 2018, and the atomizer 2 is electrically connected to the electrode 220. When the guide protrusion 180 slides out of the guide groove 202 and abuts against the top surface 2018, the atomizer holder 100 and the atomizers 2 are raised by a predetermined height, and the atomizer holder 100 avoids the electrode 220.
In this embodiment, referring to FIGS. 2 and 3, a plurality of guide protrusions 180 arranged along the circumferential direction at intervals are formed on the side of the atomizer holder 100 facing towards the electrode holder 210, and a plurality of grooves 202 arranged along the circumferential direction at intervals are formed on the side of the electrode holder 210 facing towards the atomizer holder 100. At the beginning of the rotation of the atomizer holder 100, the guide protrusion 180 slides out of one of the guide grooves 202, and is pressed against the top surface 2018 of the electrode holder 210. At the end of the rotation of the atomizer holder 100, the guide protrusion 180 is engaged into another guide groove 202. With the above design, the friction against the electrode 220 can be reduced. In addition, in the process of rotating the atomizer holder by the user, the guide protrusion 180 is sequentially engaged into the guide grooves 202, which will produce a resistance feedback, so as to facilitate the user to know the rotation angle of the atomizer holder 100, and increase the playability.
In this 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. It is understood that, in other embodiments of the present application, the number of guide protrusions 180 may also be different from the number of atomizers 2. For example, the number of guide protrusions 180 is an integer multiple of the number of atomizers 2, so that the replacement of one atomizer 2 can be achieved after the guide protrusion 180 slides through the integer multiple of the guide grooves 202.
In this embodiment, referring to FIG. 3, the side of the atomizer holder 100 facing towards the electrode holder 210 is also provided with an avoidance groove 110 extending along the movement trajectory of the electrode 220. The avoidance groove 110 is configured to allow the atomizer holder to avoid the electrode 220, to reduce the friction between the electrode 220 and the atomizer holder 100. Specifically, two avoidance grooves 110 are formed in the atomizer holder 100 at positions corresponding to the movement trajectories of the two electrodes 220, so as to avoid friction between the two electrodes 220 and the atomizer holder 100 during the rotation of the electrodes. In this embodiment, the avoidance groove 110 is provided in the atomizer holder 100, so that the friction between the electrode 220 and the atomizer 2 can be reduced or even avoided, the wear of the gold plating layer of the electrode 220 can be reduced, the heating atomization performance of the atomizer can be improved, and the service life of the electrode 220 can also be improved.
In this embodiment, referring to FIG. 1, a first elastic member 1400 is provided on the electrode holder 210, the first elastic member 1400 is mounted around the rotating shaft 800. A mounting frame 1500 is mounted at an end of the rotating shaft 800 facing away from the atomizer holder 100, and the first elastic member 1400 is sandwiched between the electrode holder 210 and the mounting frame 1500. In a normal use state, the first elastic member 1400 is in a non-compressed state. When the atomizer holder 100 is rotated and moves away from the electrode holder 210, the first elastic member 1400 is in a compressed state. When the rotation of the atomizer holder 100 is stopped, the atomizer holder 100 may be axially returned under the action of the elastic force of the first elastic member 1400. In addition, the first elastic member 1400 can also prevent the atomizer holder 100 from being separated from the electrode holder 210 during the rotation, to ensure the rotation stability of the atomizer holder 100.
In the present embodiment, referring to FIGS. 2 and 3, a second air inlet 211 is formed in the electrode holder 210. The atomizer holder 100 and the electrode holder 210 are rotatable relative to each other to switch the communication state between the second air inlet 211 and the first air inlet 21. Alternatively, a plurality of second air inlets 211 are formed in the electrode holder 210. The atomizer holder 100 and the electrode holder 210 are rotatable relative to each other to switch the communication state between the second air inlets 211 and at least one first air inlet 21.

A first connection port 910 is formed on the intake seal 900 at positions corresponding to second air inlets 211. By rotating the electrode holder 210 and the atomizer holder 100, the communication state between the first connection port 910 and the at least one atomizer 2 can be switched. In the use state, the intake seal 900 located between the electrode holder 210 and the atomizer 2 abuts against the electrode holder and the atomizer, and the first connection port 910 is in communication with at least one of the atomizers 2.
In this embodiment, referring to FIG. 1, the atomizing device also has a mouthpiece assembly 300 comprising a mouthpiece 310. The mouthpiece 310 is mounted on the side of the atomizer holder 100 away from the electrode holder 210. The mouthpiece 310 is in a synchronous rotational connection with the atomizer holder 100, and can cooperate with the atomizer holder to allow an axial limiting. The mouthpiece 310 may rotate with the atomizer holder 100.
In particular, referring to FIG. 1, the mouthpiece 310 is nested onto the atomizer holder 100. The mouthpiece 310 is provided with a convex ring 317 protruding from the outer peripheral wall of the mouthpiece, and the inner peripheral wall of the atomizer holder 100 is provided with a positioning groove 190. Both the convex ring 317 and the positioning groove 190 extend along the circumferential direction of the atomizing device. When the mouthpiece 310 and the atomizer holder 100 are nested in the axial direction of the atomizing device, the convex ring 317 is engaged in the positioning groove 190 in the axial direction of the atomizing device to form an axial limit for the mouthpiece 310 and the atomizer holder 100.
Further, a limiting bar protruding from the outer peripheral wall of the mouthpiece 310 may be provided, and a bar-shaped groove may be provided in the inner peripheral wall of the atomizer holder 100. Both the limiting bar and the bar-shaped groove extend in the axial direction of the atomizing device. When the mouthpiece 310 and the atomizer holder 100 are nested in the axial direction of the atomizing device, the limiting bar is inserted into the bar-shaped groove in the axial direction, thereby forming a synchronous rotational connection between the atomizer holder 100 and the mouthpiece 310. It will be understood that in other embodiments of the present application, the mouthpiece 310 and the atomizer holder 100 may also be made in one piece, or the mouthpiece may be welded, bonded, or screwed to the atomizer holder.
In this embodiment, referring to FIG. 1, the mouthpiece assembly 300 further comprises a mouthpiece seal 320. The mouthpiece seal is attached to the inner side of the mouthpiece 310, and sandwiched between the mouthpiece 310 and the atomizers 2. The mouthpiece 310 has a first outlet 311, the mouthpiece seal 320 has a plurality of second connection ports 321. Each second connection port 321 is configured to communicate with the second outlet 22 in each atomizer 2 in one-to-one correspondence manner, to realize the sealed connection between each atomizer 2 and the mouthpiece 310, so that each atomizer 2 may be in communication with the corresponding second connection port 321 in any state. That is, each atomizer 2 is in communication with the first outlet 311, and it is not necessary to switch the state of the first outlet 311.
In one embodiment, referring to FIGS. 1 and 5, the atomizing device further comprises a control unit 600 comprising a circuit board 610 and an airflow sensor 620. The electrode 220 is electrically connected to the circuit board 610, and the airflow sensor 620 is electrically connected to the circuit board 610. The airflow sensor 620 is configured to sense airflow when the user inhales at the mouthpiece 310, and feed the result to the circuit board 610. The circuit board 610 powers the atomizer 2 through the electrodes 220, thereby activating the atomizer 2 to heat and atomize the aerosol-generating substrate inside the atomizer to form an aerosol. Eventually, the aerosol is discharged through the first outlet 311.
Referring to FIG. 5, the electrode holder 210 is provided with a second air inlet 211 and a negative pressure hole 213 spaced apart from each other. A receiving groove 212 is formed on the side of the electrode holder 210 away from the atomizer holder 100, a sealing sleeve630 is received in the receiving groove 212. The sealing sleeve 630 is in communication with the negative pressure hole 213, thereby causing the airflow sensor 620 to communicate with the second air inlet 211. In this way, the airflow flowing through the second air inlet 211 can be sensed by the airflow sensor 620.

Embodiment 2

The technical features of the atomizing device in this embodiment are basically the same as those of the atomizing device in the embodiment 1, and the differences are as follows: in this embodiment, referring to FIG. 6, the guide protrusions 180 are formed at the edge of the end face of the atomizer holder 100 facing towards the electrode holder 210, and correspondingly, the guide grooves 202 are formed at the edge of the end face of the electrode holder 210 facing towards the atomizer holder 100.
In this embodiment, referring to FIG. 6, the bottom of the atomizer 2 is provided with a buffer slope 24 that cooperates with the avoidance groove 110 of the atomizer holder 100, to ensure that the electrode 220 can smoothly migrate from the avoidance groove 110 to the atomizer 2, and avoid the problem of blocking the movement of the electrode 220.
Further, referring to FIG. 7, the mouthpiece assembly 300 may be connected to the atomizer holder 100 by a rotational snap 1600. When the atomizer 2 needs to be replaced, the atomizer 2 can be taken out by rotating and opening the mouthpiece assembly 300. The structure is simple and operation is easy.

Embodiment 3

The technical features of the atomizing device in this embodiment are basically the same as those of the atomizing device in the embodiment 1, and the differences are as follows: In this embodiment, referring to FIG. 8, the electrode holder 210 and the atomizer holder 100 are rotatably connected to each other. Specifically, a primary housing 400 and the atomizer holder 100 are distributed in the axial direction of atomizer 2. A rotating shaft 800 extends from the center of the primary housing 400 towards the atomizer holder 100. The atomizer holder 100 is fixedly connected to the rotating shaft 800, in particular by screw locking. The electrode holder 210 is arranged around the rotating shaft 800, and the electrode holder 210 is rotatably connected to the rotating shaft 800. In practical applications, rotating the electrode holder 210 from the outside the atomizing device causes the electrode holder 210 to rotate relative to the atomizer holder 100 to realize the use state switching of at least one atomizer 2. In this embodiment, the primary housing 400 is fixedly connected to the atomizer holder 100, and a part of the power supply assembly 200 (the electrode holder 210 and the electrode 220) can be rotated relative to the atomizer holder 100 to switch the use state of at least one atomizer 2.
In this embodiment, two conductive rings 214 are formed on the side of the electrode holder 210 facing towards the primary housing 400. The two conductive rings 214 are electrically connected to two electrodes 220 respectively. Specifically, each of the two conductive rings 214 has an extension 2141 extending towards the electrode 220. The outer peripheral wall of the electrode 220 is in contact with the extension 2141, to form the electrical connection between the conductive ring 214 and the electrode 220. The primary housing 400 is provided with two electrode holes 440, in each of which a conductive post 1200 is provided. The two conductive posts 1200 are electrically connected to the circuit board 610 by wires, respectively. The two conductive posts 1200 are resiliently abutted against the two conductive rings 214 respectively. During the rotation of the electrode holder 210, the conductive post 1200 elastically abuts different portions of the conductive ring 214, thereby allowing the electrode 220 to remain electrically connected to the circuit board 610 during the rotation of the electrode holder 210. In this embodiment, since the wires are connected between the conductive posts 1200 and the circuit board 610 which are stationary with respect to each other, the wires do not twist or bend due to the rotation of the electrode holder 210, which ensures the stability of the electrical connection.
In the present embodiment, referring to FIG. 10, a plurality of first air holes 430 are formed in the primary housing 400, and the first air holes 430 are arranged at intervals along the circumferential direction of the primary housing 400. Each of the first air holes 430 passes through the primary housing 400 to communicate with the outside atmosphere. During the rotation of the electrode holder 210, the first air holes 430 sequentially communicate with the second air inlet 211 on the electrode holder 210 to communicate with the first air inlet 21 of the atomizer 2 through the second air inlet 211, thereby realizing the communication of the first air inlet 21 with the outside atmosphere.
Referring to FIG. 8, the sealing sleeve630 is mounted in the primary housing 400. The first side of the sealing sleeve630 abuts against the side of the primary housing 400 away from the electrode holder 210. An annular groove 631 is formed on the first side of the sealing sleeve630. Each of the first air holes 430 is in communication with the annular groove 631. The sealing sleeve630 is provided with a second air hole 632 and a third air hole 633 axially passing through the seal sleeve. The second air hole 632 is configured to fluidly communicate the annular groove 631 with the outside atmosphere, and the third air hole 633 is configured to fluidly communicate the annular groove 631 with the airflow sensor 620.
In this embodiment, the mouthpiece 310 is connected to the atomizer holder 100, and mouthpiece 310 is relatively stationary with respect to atomizer holder 100.

Embodiment 4

The technical features of the atomizing device in this embodiment are basically the same as those of the atomizing device in the embodiment 1, and the differences are as follows: referring to FIG. 12, the atomizer holder 100 and the electrode holder 210 are distributed in the axial direction of the atomizing device, and the atomizer holder 100 and electrode holder 210 are rotatablely connected to each other. Specifically, the primary housing 400 comprises an upper housing 410 and a lower housing 420. The upper housing 410 is arranged around the atomizer holder 100 and fixedly connected to the atomizer holder 100. The lower housing 420 is arranged around the electrode holder 210, and the lower housing 420 is connected to the electrode holder 210 by snap fit. A bottom of the atomizer holder 100 and the lower housing 420 are rotatablely connected to each other, to form the rotatable connection between the atomizer holder 100 and the electrode holder 210 through the lower housing 420. That is, the entire power supply assembly 200 is rotatablely connected to the atomizer holder 100.
In this embodiment, a plurality of guide protrusions 180 arranged along the circumferential direction at intervals are formed on the side of the atomizer holder 100 facing towards the electrode holder 210, and a plurality of guide grooves 202 arranged along the circumferential direction at intervals are formed on the side of the electrode holder 210 facing towards the atomizer holder 100. Unlike the embodiment 1, each guide protrusion 180 is formed on a perimeter edge of the atomizer holder 100, and each guide groove 202 is formed on a perimeter edge of the electrode holder 210.
In this embodiment, referring to FIG. 12, a mouthpiece 310 is provided on the side of the atomizer holder 100 away from the electrode holder 210. The mouthpiece 310 is in a synchronously slidable connection with atomizer holder 100 in the axial direction of atomizing device. The mouthpiece 310 is in a synchronous rotational connection with the electrode holder 210. The expression "mouthpiece 310 is in a synchronous rotational connection with the electrode holder 210" means that there is no relative rotation between the mouthpiece 310 and the electrode holder 210. When the atomizer holder 100 rotates relative to electrode holder 210, the mouthpiece 310 does not rotate with the rotation of the atomizer holder 100, and the mouthpiece 310 always corresponds to electrode holder 210 along the circumferential direction. When it is necessary to switch the use state of the atomizer 2, the atomizer 2 in the use state can align with the mouthpiece 310 by only rotating the atomizer 2 to a predetermined position, and it is not necessary to rotate the mouthpiece 310 after the atomizer 2 is rotated to the predetermined position, thus the operation is simple. Further, the mouthpiece 310 is in a synchronously slidable connection with atomizer holder 100 in the axial direction, such that when the atomizer holder 100 is rotated and moved axially, the mouthpiece 310 is driven to move axially. In this way, on the one hand, the interference between the atomizer holder 100 and the mouthpiece 310 is avoided, and on the other hand, it is not necessary to axially align the atomizer holder 100 with the mouthpiece 310 after the rotation of the atomizer holder 100, which reduces the operation difficulty.
In this embodiment, referring to FIG. 12, a first outlet 311 is formed in the mouthpiece 310, and a second connection port 321 is formed in the mouthpiece seal 320. When the atomizers 2 rotate along with the atomizer holder 100, the second connection port 321 sequentially communicates with the second outlets 22 of the atomizers 2, thereby realizing the switching of discharge state of the atomizers 2. That is, in this embodiment, it is only necessary to rotate the atomizer holder 100 to realize the synchronous switching of the electrical connection state, the air intake and discharge state of the atomizers 2.
In this embodiment, referring to FIG. 13, a connecting post 312 is formed on the mouthpiece 310, and the connecting post 312 is disposed to extend through the center of the atomizer holder 100. An inserting portion 313 is formed on the connecting post 312, and a first slot 215 is formed on the electrode holder 210. The inserting portion 313 passes through the first slot 215, to form the synchronous rotational connection between the mouthpiece 310 and the electrode holder 210. A stopper portion 314 is provided on a side of the inserting portion 313 away from the mouthpiece 310. The stopper portion 314 is configured to be stopped by a side of the first slot 215 away from the mouthpiece 310. The travel of the stopper portion 314 in the axial direction of the atomizer holder 100 is greater than or equal to the sliding travel in the axial direction of the atomizer holder 100.
It should be noted that, the face of the first slot 215 on the side away from the mouthpiece 310 is a stop face. When the entire aerosol generating device is in the working state, there is a distance between the stopper portion 314 and the stop surface. Said distance is the travel of the stopper portion 314. When mouthpiece 310 is moved with the atomizer holder 100, the stopper portion 314 may move within the scope of the travel. When the movement of the mouthpiece away from the electrode holder 210 reaches the end of the travel, the stopper portion 314 abuts against the stop surface, thereby preventing the mouthpiece 310 from disengaging from the electrode holder 210.
In this embodiment, referring to FIG. 13, a return assembly 700 is provided between the mouthpiece 310 and the electrode holder 210. The return assembly 700 is configured to return the mouthpiece 310 after the mouthpiece 310 moves with atomizer holder 100 in a direction away from the electrode holder 210 by a predetermined distance.
Specifically, referring to FIG. 13, the return assembly 700 comprises a second elastic member 710, a first mounting post 720, a first locking member 730, a second mounting post 740, and a second locking member 750. The second elastic member 710 is a cylindrical spring. The first mounting post 720 is mounted to the mouthpiece 310 by the first locking member 730. The second mounting post 740 is mounted to the electrode holder 210 by the second locking member 750. The cylindrical spring is disposed around the first mounting post 720 and the second mounting post 740, and is fixed to the mouthpiece 310 and the electrode holder 210. The first mounting post 720 and the second mounting post 740 are arranged in such a way that one end of the second elastic member 710 is connected to the mouthpiece 310, and the other end of the second elastic member 710 is connected to the electrode holder 210, to return the mouthpiece 310 by a pulling force of the second elastic member 710. The tension and compression of the cylindrical spring can be guided to ensure a smooth return of the mouthpiece 310. It will be appreciated that, in other embodiments, it is also possible to have only the first mounting post 720 connected to the mouthpiece 310, or only the second mounting post 740 connected to the electrode holder 210. Further, in other embodiments, the second elastic member 710 may also be an elastic sheet, an elastic cord, or other elastic elements. The return assembly 700 may also be a magnetic assembly.
In this embodiment, referring to FIG. 12, the atomizers 2 abut against both of the mouthpiece seal 320 and the atomizer holder 100 in the axial direction of the atomizing device, so that the mouthpiece seal 320 and the mouthpiece 310 can be raised as the atomizer holder 100 raise in a direction away from the electrode holder 210. In addition, since the return assembly 700 is connected between the mouthpiece 310 and the electrode holder 210, when the return assembly 700 drives the mouthpiece 310 to axially return, the atomizer holder 100 can also be driven to axially return. In this way, the atomizer holder 100 and the mouthpiece 310 can be synchronously slidably connected to each other in the axial direction of the atomizing device.

Embodiment 5:

The technical features of the atomizing device in this embodiment are basically the same as those of the atomizing device in the embodiment 1, and the differences are as follows: In this embodiment, referring to FIG. 14, the atomizing device further comprises a mouthpiece 310 which is in a synchronous rotational connection with the electrode holder 210. In this way, when the electrode holder 210 and the atomizer holder 100 rotate relative to each other, the electrical connection state, the air intake state and the discharge state of the atomizer 2 can be switched simultaneously.
It should be noted that the "the mouthpiece 310 is in a synchronous rotational connection with the electrode holder 210" refers to that the relative rotation between the mouthpiece 310 and the electrode holder 210 is limited, which may be achieved by a limiting cooperation structure between the mouthpiece 310 and the electrode holder 210, or by a direct fixedly connecting the mouthpiece 310 to the electrode holder 210, making the mouthpiece 310 in one piece with the electrode holder 210, or detachably connecting the mouthpiece 310 to the electrode holder 210 by snap fit, etc.
In this embodiment, referring to FIG. 14, the mouthpiece 310 and the electrode holder 210 are connected to opposite ends of the rotating shaft 800 respectively, and the atomizer holder 100 is rotatably mounted around a rotating shaft 800 and is located between the mouthpiece 310 and the electrode holder 210. In this embodiment, the mouthpiece 310 and the electrode holder 210 are connected to opposite ends of the rotating shaft 800 respectively , so that the connection between the mouthpiece 310 and the electrode holder 210 can be formed by the rotating shaft 800. When switching the state of the atomizer, the atomizer holder 100 may be rotated to drive the atomizers 2 to rotate, thereby switching the electrical connection state, the air intake state and the discharge state of the atomizers 2. Alternatively, the electrode holder 210 or the mouthpiece 310 may be driven so that the electrode holder 210 and the mouthpiece 310 rotate synchronously, thereby switching the electrical connection state, the air intake state and the discharge state of the atomizers 2. The operation is simple and convenient.
In this embodiment, referring to FIG. 14, the mouthpiece 310 and the rotating shaft 800 are separate elements, the electrode holder 210 and the rotating shaft 800 are separate elements, that is, the rotating shaft 800, the mouthpiece 310 and the electrode holder 210 are manufactured independently and then connected to one another. In this way, the rotating shaft 800, the mouthpiece 310 and the electrode holder 210 can be independently designed according to their functional requirements, which facilitates the moulding of the shaft 800, the mouthpiece 310, and the electrode holder 210. It can be understood that, in other embodiments of the present application, the mouthpiece 310 and the rotating shaft 800 may be made in one piece, or the rotating shaft 800 and the electrode holder 210 may be made in one piece.

In this way, it is possible to improve the stability of the electrical connection between the electrode 220 and the atomizer 2, and to avoid the possibility of wear of the second electrode 220b. In addition, since the trajectory of the motion of the first electrode 220a is smaller than the trajectory of simultaneous motion of the second electrode 220b and the first electrode 220a, the atomizers 2 are not necessarily placed along a circumference, and may also be placed along a square, so that the placement of the atomizers 2 is more compact, occupies less space, and the device is easy to carry.

The arrangement of the ribs 940 ensures that each atomizer 2 and the intake seal 900 are in sealed contact with each other. In this way, not only the first air inlet 21 of the atomizer 2 in the non-use state can be blocked, but also the first air inlet 21 of the atomizer in the use state can be hermetically connected to the second air inlet 211.
In this embodiment, referring to FIGS. 26 and 29, a plurality of engagement grooves 251 are provided on the side of the motion frame 250 facing towards the intake seal 900, and a plurality of engagement portions 920 are provided on the side of the intake seal 900 facing towards the motion frame 250.

In addition, since resistance is generated when the first ridge 255 is engaged between the two second ridges, it is possible to prompt the user whether or not the first ridge 255 is engaged, and it is possible to reduce the start failure caused by the shift failure. The number of first ridges 255, the number of sets of second ridges, and the number of atomizers 2 are the same.
In this embodiment, referring to FIG. 25, the atomizing device also comprises a primary housing 400 mounted around the fixed frame 240 and the atomizer holder 100. The motion frame 250 extends to the bottom of the primary housing 400. A toggle portion 256 is provided on the outside of the bottom portion of the motion frame 250. By rotating the toggle portion 256 at the bottom of the entire atomizing device, the motion frame 250, the first electrode 220a, and the second air inlet 211 can be rotated, thereby realizing the switching of the use state of the atomizer 2. Therefore, the operation is convenient, and the appearance of the atomizing device is smooth and beautiful.
In this embodiment, referring to FIG. 25, the mouthpiece 310 and the atomizer holder 100 are nested to one another by a snap fit, allowing conveniently removing the atomizer 2 in the atomizer holder 100 and replacing it with another atomizer 2.
In this embodiment, the atomizer holder 100 and the fixed frame 240 are connected to one another by magnetic attraction, and the primary housing 400 is arranged around the atomizer holder 100 and the fixed frame 240. When it is necessary to replace the atomizer 2, the atomizer holder 100 can be easily taken out of the primary housing 400 and the mouthpiece 310 can be opened, thus realizing the convenient replacement of the atomizer 2.
In this embodiment, the airflow sensor 620 is mounted on the motion frame 250, the battery 280 is mounted on the motion frame 250, and the circuit board 610 is mounted on the fixed frame 240. The airflow sensor 620 is connected to the circuit board 610 by wires.

The slider 244 is provided with a second limiting portion 245, and the sliding of the first limiting portion 257 is stopped by opposite sides of the second limiting portion 245 along the circumferential direction. The presence of the second limiting portion 245 limits the sliding direction and the sliding travel of the first limiting portion 257, thereby limiting the rotation direction and the rotation travel of the motion frame 250. Therefore, the problem that the wire between the airflow sensor 620 and the circuit board 610 is loosened due to excessive rotation of the motion frame 250 is avoided, and the operation failure of the airflow sensor 620 can be avoided.

A motion of the airway switch 2200 is synchronously linked a motion of the circuit switch 2300. In other words, the relative position of a part of the power supply assembly 200 and the atomizer holder 100 is variable, to switch a use state of at least one atomizer 2.
The airway switch 2200 is movable or rotatable to open or close at least one of the second air inlets 211, but the opening and closing states of the second air inlets 211 may be different. In particular, the airway switch 2200 is capable of opening one or more of the second air inlets 211 and forcing the other second air inlets 211 to be closed. The airway switch 2200 is also capable of closing all of the second air inlets 211.
Similarly, the circuit switch 2300 may allow the electrical connection between a part of the electrodes 220 and the circuit board 610 and cut off the electrical connection between the other electrodes 220 and the circuit board 610, or cut off the electrical connection between all electrodes 220 and the circuit board 610.
Generally speaking, in this embodiment, since a motion of the airway switch 2200 is synchronously linked with a motion of the circuit switch 2300, the state switching of the electrodes 220 and the second air inlets 211 can be realized by only moving or rotating the airway switch 2200 or the circuit switch 2300, which is simple in operation.
In the present embodiment, there are N atomizers 2 in the atomizing device. The airway switch 2200 has M stages, that is, the airway switch 2200 has M operating positions. In each operating position of the airway switch 2200, the atomizers 2 are in different connection states.

When the airway switch 2200 is in K stage (K is equal to or less than N), only one set of electrodes 220 is energized and only one second air inlet 211 is opened. When the airway switch 2200 is in N+1 stage, all electrodes 220 are powered off, and all second air inlets 211 are closed, so as to lock the device and ensure that the aerosol generating device does not leak oil.
