It should be noted that, the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" for indicating orientation or positional relationship should be understood based on the orientation or positional relationship shown in the drawings. These directional terms are intended only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be interpreted as a restriction on the present application.
In addition, the terms "first" and "second" are used merely for descriptive purposes, and are not to be construed as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, the feature defined by "first" or "second" may explicitly or implicitly means that there is at least one said feature. In the description of the present application, "a plurality of" means two or more, unless otherwise expressly specified and limited.
Referring to FIGS. 1 to 4, an atomizing device according to an embodiment of the present application will now be described. The atomizing device comprises a power supply assembly 3, an atomizer holder 100, an electrode assembly 200, and a mouthpiece 300. The atomizer holder 100 is configured to receive a plurality of atomizers 2, the mouthpiece 300 is disposed on the atomizer holder 100, and an electrode 220 is configured to electrically connecting any of the plurality of atomizers 2 with the power supply assembly 3. The mouthpiece 300 is at least partially detachable or dissociable, so as to allow the replacement of any of the plurality of atomizers 2 in the atomizer holder 100.
It should be noted that the expression "the mouthpiece 300 is at least partially detachable or dissociable" comprises the following meanings: 1) the mouthpiece 300 is entirely detachable; or, 2) the mouthpiece 300 is entirely dissociable; or, 3) a part of the mouthpiece 300 is detachable form the mouthpiece 300; or, 4) a part of the mouthpiece 300 is dissociable relative to the mouthpiece 300. In general, in either way, each atomizer 2 in the atomizer holder 100 can be removed from the location of the mouthpiece 300, to replace the atomizer 2 with a new atomizer or the atomizer with different flavor to meet the user's inhalation needs.
It should be noted that the expression "the mouthpiece 300 is entirely detachable" means that the entire mouthpiece 300 can be detached from the atomizing device. The expression "a part of the mouthpiece 300 is detachable" means that a part of the mouthpiece 300 (e.g. a cover plate) is detachable from the mouthpiece 300.
In the present application, the term "dissociable" refers to a case where a dissociable part can be partially separated from a main body but not completely separated from the main body, and for example, the dissociable part can be opened by rotation or sliding with respect to the main body. Specifically, the expression "the mouthpiece 300 is entirely dissociable" means that the mouthpiece 300 can be rotationally opened or slidably opened relative to the atomizing device. The expression "a part of the mouthpiece 300 is dissociable relative to the mouthpiece 300 means that the part of the mouthpiece 300 can be opened relative to the mouthpiece 300 by rotation or sliding.
In the atomizing device of the embodiment of the present application, by means of the mouthpiece 300 which is at least partially detachable or dissociable, the atomizer 2 in the atomizer holder 100 can be replaced. It is convenient for the user to take out the atomizer 2 from the location of the mouthpiece 300 to replace it with a new atomizer 2, thereby improving the service life of the atomizing device and reducing the cost of the atomizing device. In addition, users can replace the atomizer with an atomizer with different flavors according to their own preferences, to improve the user experience.
In the present application, depending on the connection manner of the electrode assembly 200 to the mouthpiece 300, the replacement of the atomizer 2 may comprises different manners. For example, when the connection of the electrode assembly 200 with the mouthpiece 300 is formed across the atomizer holder 100, the mouthpiece 300 cannot be easily detached, and the replacement of the atomizer 2 can be achieved by providing an openable cover on the mouthpiece 300. Of course, the mouthpiece 300 may be detachably connected to the electrode assembly 200 to allow the replacement of any of the plurality of atomizers 2. For another example, when the mouthpiece 300 is not directly connected to the electrode holder 210, the mouthpiece 300 may be detachably connected to the atomizer holder 100 to allow the replacement of any of the plurality of atomizers 2. Of course, it may also provide an openable cover on the mouthpiece 300.
A plurality of atomizers 2 are received in the atomizer holder 100. The atomizer 2 electrically connected to the electrode assembly may be switched by the relative rotation of the atomizer holder 100 with respect to the electrode assembly 200, and the atomizer 2 electrically connected to the electrode assembly may be switched by the relative sliding of the atomizer holder 100 with respect to the electrode assembly 200.
In the following example, the atomizer holder 100 and the electrode holder 210 are rotatable relative to each other, and the connection of the mouthpiece 300 with the electrode assembly 200 is formed across the atomizer holder 100. The replacement of the atomizer 2 in this example in described hereinafter in detail.
In one embodiment, referring to FIGS. 3 and 4, the electrode assembly 200 comprises an electrode holder 210 and an electrode 220 disposed on the electrode holder 210. The electrode holder 210 and the atomizer holder 100 are rotatably connected to each other, and the mouthpiece 300 is at least partially detachable or dissociable, to allow the replacement of any of the plurality of atomizers 2. By driving the electrode holder 210 to rotate relative to the atomizer holder 100, the relative position between the electrode 220 and the atomizers 2 can be adjusted, thereby realizing the electrical connection to a respective one of the atomizers 2.
Specifically, referring to FIG. 2, the atomizer holder 100 accommodates a plurality of atomizers 2 that are distributed at intervals in the circumferential direction. Each atomizer 2 is provided with at least one conductive post 23. Every time the electrode holder 210 and the atomizer holder 100 are rotated relative to one another by a preset angle, the relative position between the electrode 220 and atomizers 2 can be adjusted to establish an electrical connection between the electrode 220 and the conductive post 23 of a respective one of the atomizers 2, so that this atomizer 2 is energized to start operation.
In one embodiment, referring to FIG. 4, the mouthpiece 300 is in a synchronous rotational connection with the electrode holder 210. The synchronous rotational connection means that the connection of the mouthpiece 300 and the electrode holder 210 allows them to rotate synchronously. For example, the mouthpiece 300 may be fixedly connected to the electrode holder 210 directly, or the synchronous rotation may be realized simply by forming a circumferential limit between the mouthpiece 300 and the electrode holder 210. In this embodiment, the mouthpiece 300 and the electrode holder 210 can rotate synchronously. It is possible to adjust the relative positions between the electrode 220 and the atomizers 2, as well as the relative positions between the mouthpiece 300 and the atomizers 2 by only one of the mouthpiece 300, the atomizer holder 100 and the electrode holder 210 to rotate. Furthermore, the mouthpiece 300 is at least partially detachable or dissociable to allow the replacement of any of the plurality of atomizers 2. When replacing the atomizer 2, the mouthpiece 300 may be detached from the electrode holder 210, or the cover on the mouthpiece 300 may be opened.
In one embodiment, the synchronous rotation of the mouthpiece and electrode holder is achieved by forming a circumferential limit between the mouthpiece 300 and the electrode holder 210, and the entire mouthpiece 300 can be integrally detached from the electrode holder 210. Specifically, referring to FIGS. 5 and 6, the mouthpiece 300 comprises a snap portion 340, and the electrode holder 210 comprises a slot 212. The snap portion 340 is joined onto the electrode holder 210 via the slot 212, to form a synchronous rotational connection between the mouthpiece 300 and the electrode holder 210, and to allow the mouthpiece 300 to be detachable from the electrode holder 210. In this embodiment, the connection between the mouthpiece 300 and the electrode holder 210 is formed by a cooperation of the snap portion 340 and the slot 212, so that the mouthpiece 300 is detachable from the electrode holder 210. When replacing the atomizer 2, the mouthpiece 300 can be entirely detached from the electrode holder to allow the replacement of any of the plurality of atomizers.
In particular, referring to FIG. 6, a connecting post 330 is formed on the mouthpiece 300, and the connecting post 330 is arranged to extend through the center of the atomizer holder 100. The snap portion 340 is formed on the connecting post 330. The side of the snap portion 340 away from the mouthpiece 300 is provided with a hook portion 350, the side of the slot 212 away from the mouthpiece 300 is configured to stop the hook portion 350.
In the embodiment of the detachable mouthpiece 300, referring to FIG. 6, the mouthpiece 300 forms a snap fit with the slot 212 through the snap portion 340. The hook portion 350 is formed on the snap portion 340, and the hook portion 350 may abut against a stop surface on the side of the slot 212 away from the mouthpiece 300. However, when an external force applied to the hook portion 350 is greater than the force required to deform the hook portion, the hook portion 350 will deform and disengage from the slot 212, thereby allowing the mouthpiece 300 to be detached from the electrode holder 210.
In the above embodiment, guide surfaces may be provided on the inner side walls of the hook portion 350 and the slot 212 respectively, so as to guide the hook portion 350 to be inserted into the slot 212, and guide the hook portion 350 to be disengaged from the slot 212.
In one embodiment, referring to FIG. 6, the mouthpiece 300 further comprises a body 310 and an inhalation portion 320 protruding from an outer side of the body 310. A first outlet 380 passes through the inhalation portion 320 and the body 310. The connecting post 330 is connected to a side of body 310 away from the inhalation portion 320, and the body 310 abuts against the atomizers 2.
In this embodiment, the detachable connection between the mouthpiece 300 and the electrode holder 210 is formed by snap-fitting, so that the entire mouthpiece 300 can be detached to allow the replacement of any of the plurality of atomizers 2. It should be understood that in other embodiments of the present application, a synchronous rotational connection may also be formed between the mouthpiece 300 and the electrode holder 210 by screw locking. In this case, the mouthpiece 300 is not detachable, and an openable cover may be provided on the mouthpiece 300 to allow the replacement of any of the plurality of atomizers 2.
In another embodiment of the present application, the atomizer 2 can also be replaced in other manners. For example, referring to FIG. 9, instead of detaching the mouthpiece 300, a window 311 may be arranged on the mouthpiece 300, and the atomizer 2 may be replaced through the window 311, thereby avoiding the detaching and mounting of the mouthpiece 300. Specifically, the mouthpiece 300 and the atomizer holder 100 are rotatable relative to each other. By driving the atomizer holder 100 to rotate, the window 311 on the mouthpiece 300 can face towards the atomizer 2 to be replaced, thereby facilitating the removal of the atomizer 2.
In the embodiment where the mouthpiece 300 is not detachable, referring to FIG. 7, the mouthpiece 300 and the atomizer holder 100 are rotatably connected to each other, the window 311 for passage of any of the plurality of atomizers 2 is formed on the mouthpiece, and the window 311 is provided with a cover 360 that can be opened. When the atomizer 2 needs to be replaced, the cover 360 is opened at first, and then the atomizer 2 is removed from the window 311. A new atomizer 2 is then placed into the atomizer holder 100 from the window 311, and finally the cover 360 is closed. Further, when the atomizer 2 to be replaced does not correspond to the window 311, the atomizer holder 100 may be rotated to enable the atomizer 2 to be replaced to correspond to the window 311.
In the embodiment where the mouthpiece 300 is not detachable, the mouthpiece 300 is provided with a rotatable rotating shaft 370. One end of the cover 360 is fixed to the rotating shaft 370. A torsion spring is provided on the rotating shaft 370, one end of the torsion spring is connected to the rotating shaft 370, and the other end of the torsion spring is connected to the mouthpiece 300. In addition, a locking structure is provided between the mouthpiece 300 and the cover 360. When the cover 360 is closed, the cover is locked by the locking structure to keep the cover 360 in the closed state. When the cover 360 needs to be opened, the locking structure can be separated from the cover 360, and the cover 360 can be opened under the action of a driving force of the torsion spring. It can be understood that in other embodiments, the rotating shaft 370 may be fixedly arranged on the mouthpiece 300, the cover 360 may be rotatably connected to the rotating shaft 370, one end of the torsion spring may be connected to the rotating shaft 370, and the other end of the torsion spring may be connected to the cover 360, to realize the open action of the cover 360.
In the above embodiment, referring to FIG. 7, the locking structure comprises a first locking member 361 arranged on the cover 360 and a second locking member (not shown) arranged on the mouthpiece 300, and the first locking member 361 is configured to be snap-fitted to the second locking member. In addition, a notch 362 is formed at the outer edge of an end of the cover 360 away from the rotating shaft 370, and when it is necessary to open the cover 360, the user may insert his finger into notch 362 to open the cover 360.
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 preferably has a compressible elastic pin or a compressible elastic tongue.
Further, in one embodiment, 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 (angular position) 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, a respective one of the atomizers 2 (for example, a first atomizer) 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, another one of the 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 preset angle, that is, the electrical connection state of atomizers 2 is switched once, specifically, the electrical connection of the electrode 220 to one atomizer 2 is switched to the electrical connection of the electrode 220 to the next 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 embodiment, 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 a respective one of the atomizers 2, and 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.
Next, 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 relative to each other 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 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 FIGS. 8 to 10, the atomizer holder 100 has a first cooperating face 141, and the electrode holder 210 has a second cooperating face 214 that slidably cooperates with the first cooperating face 141. The first cooperating face 141 and the second cooperating face 214 are disposed opposite to each other one in the axial direction of the atomizing device. The second cooperating face 214 has a first position 2141, a second position 2142, and a third position 2143. When the first cooperating face 141 is located at the first position 2141, the atomizer holder 100 is in the first orientation with respect to the electrode 220, when the first cooperating face 141 is located at the second position 2142, the atomizer holder 100 is in the second orientation with respect to the electrode 220, and when the first cooperating face 141 is located at the third position 2143, the atomizer holder 100 is in the third orientation with respect to the electrode 220.
The first position 2141, the second position 2142, and the third position 2143 are positions at which the second cooperating face 214 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 2141, the second position 2142, and the third position 2143 are sequentially distributed in 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 141 slides from the first position 2141 of the second cooperating face 214 to the second position 2142, and then slides from the second position 2142 to the third position 2143. By changing the cooperating position of the first cooperating surface 141 and the second cooperating face 214, 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 214 may be formed on the atomizer holder 100, and the first cooperating face 141 may be formed on the electrode holder 210.
In one embodiment, referring to FIG. 9, the second cooperating surface 214 has a plurality of trough faces 2144 arranged in the circumferential direction at intervals, and a peak face 2145 is connected between each two adjacent trough faces 2144. When the first cooperating face 141 cooperates with the trough face 2144, the atomizer holder 100 is in the first or third orientation with respect to the electrode. When the first cooperating face 141 cooperates with the peak face 2145, the atomizer holder 100 is in the second orientation with respect to the electrode.
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 141 slides from one trough face 2144 of the second cooperating face 214 to a peak face 2145 and then to a next trough face 2144. Said one trough face is the first position 2141 of the second cooperating face 214, the next trough face 2144 is the third position 2143 of the second cooperating face 214, and said one peak face 2145 is the second position 2142 of the second cooperating face 214. That is, one trough face 2144, one peak face 2145 and one trough face 2144 connected in sequence exactly correspond to the first position 2141, the second position 2142, and the third position 2143.
In this embodiment, trough faces 2144 and peak faces 2145 are provided. When the first cooperating face 141 slides to the trough face 2144, 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 141 slides to the peak face 2145, 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 one embodiment, referring to FIG. 9, the peak face 2145 is trapezoidal. Specifically, the peak face 2145 comprises an uphill section 2146, a downhill section 2147, and a top surface 2148. The top surface 2148 is the portion of peak face 2145 that attains the maximum distance from the trough face 2144. The uphill section 2146 is connected between one trough face 2144 and the top surface 2148, and a downhill section 2147 is connected between the top surface 2148 and the next trough face 2144. The top surface 2148 is planar. It can be understood that, in other embodiments of the present application, referring to FIG. 10, the peak face 2145 may also be triangular, or the peak face 2145 may also be curved or wavy, and the present invention is not limited thereto.
In the present application, specific positions and specific implementation structures of the first cooperating face 141 and the second cooperating face 214 will be described below.
In one embodiment, referring to FIGS. 8 and 11, the first cooperating face 141 may be disposed on the end face of the atomizer holder 100 facing the electrode holder 210. In this case, the guide protrusion 140 may be formed on the atomizer holder 100, and the first cooperating face 141 is the face of the guide protrusion 140 facing towards the electrode holder 210. Correspondingly, the second cooperating face 214 may be disposed on the end face of the electrode holder 210 facing towards the atomizer holder 100. In this case, the electrode holder 210 may be provided with a plurality of grooves 215 in the circumferential direction at intervals. The bottom face of the groove 215 is the trough face 2144, and the end surface of the electrode holder 210 is the top surface 2148. When the guide protrusion 140 slides into the groove 215, the end face of the atomizer holder 100 abuts against the end face of the electrode holder 210, and the atomizer 2 is electrically connected to the electrode 220. When the guide protrusion 140 slides out of the groove 215 and abuts against the end face of the electrode holder 210, the atomizer holder 100 and atomizer 2 are raised by a predetermined height, and the atomizer holder 100 may avoid the electrode 220.
In this embodiment, referring to FIGS. 2 and 3, a plurality of guide protrusions 140 arranged in 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 215 arranged in 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 140 slides out of one of the grooves 215, and is pressed against the top surface 2148 of the electrode holder 210. At the end of the rotation of the atomizer holder 100, the guide protrusion 140 is engaged into another groove 215. 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 140 is sequentially engaged into the grooves 215, which will produce a tactile 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 height of the guide protrusion 140 in the axial direction of the atomizer holder 100 is the predetermined height. That is, when the guide protrusion 140 slides out of the groove 215, the atomizer holder 100 can be raised by the predetermined height.
In one embodiment, the number of grooves 215 is the same as the number of atomizers 2, and the number of guide protrusions 140 is the same as the number of atomizers 2. In this way, the process of sliding the guide protrusion 140 out of one groove 215 and into another groove 215 just corresponds to the rotation of the atomizer holder 100 by the preset angle, so as to realize the replacement of one atomizer 2, and facilitate the rotation control. It is understood that in other embodiments of the present application, the number of guide protrusions 140 may also be different from the number of atomizers 2. For example, the number of guide protrusions 140 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 140 slides through the integer multiple of the grooves 215.
In the above embodiment, the second cooperating face 214 may be disposed on the periphery of the electrode holder 210, and the second cooperating face 214 may also be disposed on the electrode holder 210 around a position of the central axis.
In the present application, it is possible to avoid the problem that the mouthpiece 300 needs to be axially aligned with the atomizer holder 100 after rotation due to the axial sliding of the mouthpiece 300 along with the electrode holder 210. In one embodiment, the mouthpiece 300 is slidably connected to the electrode holder 210 along the axial direction of the atomizing device. The atomizer holder 100 is rotatable relative to the electrode holder 210 while driving the mouthpiece 300 to slide in the axial direction of the atomizing device relative to the electrode holder 210. The mouthpiece 300 is slidably connected to the electrode holder 210 in the axial direction of the atomizing device. When the electrode holder 210 and the atomizer holder 100 rotate and move axially, the mouthpiece 300 will rotate with the rotation of the electrode holder 210, so that the electrical connection and air outlet of the atomizers 2 are simultaneously switched. However, the mouthpiece 300 does not move with the electrode holder 210, so that the mouthpiece 300 and the atomizer holder 100 can be axially synchronized. Furthermore, the connection between the mouthpiece 300 and the atomizer holder 100 allow an axial limit, so that the mouthpiece 300 can remain in axial abutment with the atomizer holder 100 when the electrode holder 210 rotates and rises or falls. In this way, on the one hand, the interference between the atomizer holder 100 and the mouthpiece 300 is avoided, and on the other hand, it is not necessary to axially align the atomizer holder 100 with the mouthpiece 300 after the rotation of the atomizer holder 100, which reduces the operation difficulty.
The sliding connection of the mouthpiece 300 to the electrode holder 210 in the axial direction of the atomizing device is achieved by the cooperation of the snap portion 340 and the slot 212. Specifically, referring to FIG. 7, the face of the slot 212 on the side away from the mouthpiece 300 is a stop face. When the entire aerosol generating device is in the working state, there is a distance between the hook portion 350 and the stop surface. Said distance is the movable stroke of the hook portion 350. When mouthpiece 300 is moved by atomizer holder 100, the hook portion 350 may move within the scope of the movable stroke. When the movement of the mouthpiece away from the electrode holder 210 reaches the movable stroke, the hook portion 350 abuts against the stop surface, thereby preventing the mouthpiece 300 from disengaging from the electrode holder 210.
In one embodiment, a return assembly is provided between the mouthpiece 300 and the electrode holder 210. The return assembly is configured to return the mouthpiece 300 after the mouthpiece 300 moves away from the electrode holder 210 with the movement of the atomizer holder 100, to bring the mouthpiece 300 and the electrode holder 210 into abutment in the axial direction of the atomizing device.
In one embodiment, referring to FIG. 5, the return assembly is a magnetic assembly 600. The mouthpiece 300 and the electrode holder 210 are attracted together by magnetic attraction, so that mouthpiece 300 can be returned to an initial position by the magnetic attraction after moving away from electrode holder 210.
Specifically, referring to FIG. 5, the magnetic assembly 600 comprises a first magnetic member 610 and a second magnetic member 620. The first magnetic member 610 is fixedly connected to the mouthpiece 300, and the second magnetic member 620 is fixedly connected to the electrode holder 210. In the rotation state of the atomizer holder 100, the first magnetic member 610 is separated from the second magnetic member 620. When the atomizer holder 100 stops rotating, the first magnetic member 610 and the second magnetic member 620 are mutually attracted and abutted against one another, to return the mouthpiece 300 to the initial position. In addition, when the atomizer holder 100 and the electrode holder 210 are in a relatively stationary state, the attraction between the first magnetic member 610 and the second magnetic member 620 can also make the atomizer holder 100 and the electrode holder 210 abut against each other in the axial direction of the atomizing device, so as to ensure the stability of the electrical connection between the electrode 220 and the atomizer 2.
Specifically, referring to FIG. 5, the connecting post 330 has a first mounting groove 331 extending through the bottom end of the connecting post. The first magnetic member 610 is received in the first mounting groove 331. The first magnetic member 610 and the connecting post 330 are riveted to each other by an interference fit. A second mounting groove 213 recessed inward is provided in the middle portion of the side of the electrode holder 210 facing towards the mouthpiece 300, and the second magnetic element 620 is received in the second mounting groove 213. The second magnetic member 620 is fixed at the bottom of the second mounting groove 213, and the slot 212 is distributed around the second mounting groove 213. The connecting post 330 is at least partially inserted into the second mounting groove 213 to receive the second magnetic member 620 in the connecting post 330.
In the above embodiment, when the atomizer 2 needs to be replaced, a force is first applied to the mouthpiece 300 in a direction away from the electrode holder 210. When the force is greater than the magnetic attraction force between the first magnetic member 610 and the second magnetic member 620, and the hook portion 350 can be elastically deformed and separated from the slot 212, the mouthpiece 300 can be detached and the atomizer 2 can be replaced. After replacement of the atomizer 2 is complete, the hook portion 350 is moved through the slot 212, the snap portion 340 is correspondingly inserted into the slot 212, and the mouthpiece 300 is pushed toward the electrode holder 210. The mouthpiece 300 move towards the electrode holder 210 under the magnetic attraction force between the first magnetic member 610 and the second magnetic member 620 to return to the initial position.
In another embodiment of the present application, the return assembly may also be a sucker assembly mounted on the electrode holder 210. The connecting post 330 is provided with a smooth surface, and the sucker assembly is capable of attracting the smooth surface, thereby attracting the mouthpiece 300 and the electrode holder 210 together.

In one embodiment, referring to FIGS. 2 and 3, the electrode holder 210 is provided with at least two sets of first magnets 230, and each set of the atomizers 2 is provided with a set of second magnets (not shown). Each first magnet 230 is configured to attract a second magnet of any of the plurality of atomizers. For example, if the number of atomizer 2 is four, four sets of first magnets 230 are provided on the electrode holder 210. After the rotation of the atomizer holder 100, the each set of first magnets 230 attract a respective set of second magnets, so that the atomizer 2 in the use state can be firmly connected to the electrode holder 210, and stable electrical connection between the conductive post 23 and the electrode 220 is ensured. Of course, in other embodiments, if the number of the atomizers 2 is two, three, five or more, the number of the first magnets 230 also changes accordingly, and the present invention is not limited thereto.
In one embodiment, each set of second magnets comprises two second magnets. The two second magnets are provided on opposite sides of the second air inlet 21 of the atomizer 2 respectively. Each set of first magnets 230 comprises two first magnets 230. The two second magnets correspond one-to-one to the two first magnets 230, thereby ensuring a stable connection between the atomizer 2 and the electrode holder 210. It will be appreciated that, in other embodiments of the present application, each set of first magnets 230 may comprise one magnetic block. The magnetic blocks extend in the circumferential direction of the atomizer holder 100, and the magnetic block attracts two second magnets disposed at intervals.
In another embodiment of the present application, the mouthpiece 300 may be detachably connected to the atomizer holder 100. For example, the mouthpiece 300 may be detachably connected to the atomizer holder 100 by a rotational snap, or by an interference fit.

In one embodiment, referring to FIG. 4, the atomizing device further comprises a lower housing 420 and a bottom lid 700 mounted on the side of the electrode holder 210 away from the atomizer holder 100.

In one embodiment, referring to FIG. 4, the atomizer holder 100 is provided with a friction ring 130 protruding from an outer peripheral wall of the atomizer holder. The lower housing 420 is spaced apart from the upper housing 410 in the axial direction, and the friction ring 130 is disposed between the lower housing 420 and the upper housing 410. The top end of the lower housing 420 abuts against the bottom side face of the friction ring 130, and the bottom end of the upper housing 410 abuts against the top side face of the friction ring 130. The surface of the friction ring 130 has protrusions or recesses to increase the frictional resistance of the friction ring 130. When in use, the user only needs to rotate the friction ring 130 to drive the upper housing 410, the atomizer holder 100 and the atomizers 2 to rotate synchronously, thus saving user's labor.
In one embodiment, referring to FIG. 3, a first air inlet 211 for introducing external air into the atomizer 2 is formed on the electrode holder 210.
