DETAILED DESCRIPTION

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0039] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0040] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0041] As mentioned in the background technology, the existing aerosol generating device can usually only be used with one atomizer. When replacing the atomizer, the atomizer needs to be removed from the aerosol generating device and then installed with a new atomizer. As the user's demand for atomization increases, the demand for the capacity of the atomizing medium in the aerosol generating device also increases, so a more convenient atomizer switching method is needed. In addition, users have more and more demands for the flavors of the atomizing medium, and switching between different flavors has also become mainstream.

[0042] In order to solve the above problems, the embodiment of the present application provides an atomizer and an aerosol generating device, wherein a mounting cavity for accommodating a plurality of atomizers 1000 is formed by enclosing a rotating frame 200 and / or a power supply assembly 100, and each atomizer 1000 can be driven to rotate to the use station P in sequence by driving the rotating frame 200 to rotate, thereby realizing the switching of the use state of each atomizer 1000, making the switching mode of the atomizer 1000 simpler. In addition, atomizers 1000 of various flavors can be loaded, thereby satisfying the needs of users for different flavors.

[0043] See also Figures 1 to 4 , the atomizer provided by the embodiment of the present application is now described. The atomizer comprises a power assembly 100, a rotating frame 200 and a nozzle 300, the nozzle 300 is connected to the power assembly 100 along the axial direction of the atomizer; the rotating frame 200 extends into the power assembly 100 from the side of the power assembly 100, the rotating frame 200 and / or the power assembly 100 enclose a mounting cavity for accommodating a plurality of atomizers 1000, and the rotating frame 200 can be driven to rotate to drive each atomizer 1000 to rotate to the use station P in sequence.

[0044] It should be noted that the nozzle 300 is connected to the power assembly 100 along the axial direction of the atomizer, that is, the nozzle 300 is located at one end of the power assembly 100 along the axial direction of the atomizer. The nozzle 300 and the power assembly 100 can be provided as two detachable parts, or the nozzle 300 and the power assembly 100 can be provided as one piece.

[0045] The rotating frame 200 extends into the power assembly 100 from the side of the power assembly 100. Here, the side of the power assembly 100 refers to the side of the power assembly 100 except the two opposite ends along the axis of the atomizer. In actual application, the user generally holds the atomizer by the side to hold the atomizer and sucks the nozzle 300. When the atomizer 1000 needs to be replaced or the flavor needs to be changed, the rotating frame 200 can be directly rotated on the side, which is simple to operate.

[0046] The rotating frame 200 and / or the power supply assembly 100 enclose an installation cavity. The installation cavity may be directly formed on the rotating frame 200, or completely formed on the power supply assembly 100, or the rotating frame 200 and the power supply assembly 100 may jointly enclose an installation cavity.

[0047] In addition, the above-mentioned use station P means that the atomizer 1000 rotated to the use station P is in a use state. The air inlet and outlet of the atomizer 1000 in the use state remain unobstructed, and the atomizer 1000 is electrically connected to the power supply component 100. The power supply component 100 supplies power to the atomizer 1000 so that the atomizer 1000 can heat the atomizing medium inside it and atomize it to form an aerosol. The generated aerosol can flow out through the nozzle 300.

[0048] The atomizer in the embodiment of the present application is enclosed by the rotating frame 200 and / or the power assembly 100 to form an installation cavity for accommodating multiple atomizers 1000, and by driving the rotating frame 200 to rotate, each atomizer 1000 can be driven to rotate to the use station P in turn, thereby realizing the switching of the use state of each atomizer 1000, making the switching method of the atomizer 1000 simpler, and can also load a variety of atomizers 1000 of different flavors, thereby meeting the needs of users for different tastes. At the same time, by extending the rotating frame 200 from the side of the power assembly 100 into the power assembly 100, that is, the rotating frame 200 can be rotated on the side of the power assembly 100, the atomizer 1000 can be switched, and the operation is simple and convenient.

[0049] In one embodiment, see Figure 4 The axial direction of the rotating frame 200 is the X direction indicated in the figure, and the axial direction of the rotating frame 200 and the axial direction of the atomizing device are arranged at an angle to each other, for example, the angle may be 70°, 75°, 80°, 85°, 95°, 100°, 105°, 110°, etc.

[0050] Preferably, the axial direction of the rotating frame 200 is arranged perpendicular to the axial direction of the atomizer, and each atomizer 1000 is distributed in a plane perpendicular to the axial direction of the rotating frame 200. The above arrangement can reduce the space occupied by each atomizer 1000 along the axial direction of the rotating frame 200, thereby reducing the size of the entire atomizer along the axial direction of the rotating frame 200, making it easier for users to hold.

[0051] In one embodiment, see Figure 4 , the size of the power assembly 100 along the first direction X is greater than the size of the power assembly 100 along the axial direction of the rotating frame 200, the first direction X is perpendicular to the axial direction of the atomizing device, the axial direction of the rotating frame 200 is perpendicular to the axial direction of the atomizing device, and the first direction X is perpendicular to the axial direction of the rotating frame 200. In the present application, since a plurality of atomizers 1000 need to be distributed, and each atomizer 1000 is distributed in a plane perpendicular to the axial direction of the rotating frame 200, that is, each atomizer 1000 occupies a large space along the first direction X and the axial direction of the atomizing device, this embodiment sets the size of the first direction X that each atomizer 1000 needs to occupy a large space to be greater than the axial size of the rotating frame 200, so that the structure of the entire power assembly 100 is not only compact, but also the size of the power assembly 100 is as small as possible, and is long and flat, which is convenient for users to hold.

[0052] In one embodiment, see Figures 2 to 6The rotating frame 200 includes a rotating disk 210 and a rotating cover 220. The rotating disk 210 is rotatably stored in the power supply assembly 100. The rotating disk 210 is used to support each atomizer 1000. The rotating cover 220 is detachably connected to the rotating disk 210, and the rotating cover 220 is covered on the outside of one end of each atomizer 1000. In this embodiment, the rotating frame 200 is divided into a rotating disk 210 and a rotating cover 220, and each atomizer 1000 is supported by the rotating disk 210, so that the atomizer 1000 can be stably assembled between the rotating disk 210 and the rotating cover 220, which facilitates the rotating frame 200 to rotate and switch each atomizer 1000. When the atomizer 1000 needs to be replaced, it only needs to open the rotating cover 220 to take out and replace the atomizer 1000, which is simple to operate. It can be understood that in other embodiments of the present application, the turntable 210 and the rotating cover 220 may also be an integrated structure. In this case, the atomizer 1000 may not be supported on the turntable 210, but the atomizer 1000 may be supported by the power supply assembly 100, and the rotating frame 200 is only used to drive the atomizer 1000 to rotate, which is not the only limitation here.

[0053] In one embodiment, see Figures 3 to 5 The side of the power supply assembly 100 is concave to form a storage cavity 1110, the turntable 210 is rotatably arranged in the storage cavity 1110, and the rotating cover 220 is assembled at the cavity opening position of the storage cavity 1110, and the user can rotate the rotating cover 220 from the outside.

[0054] In one embodiment, see Figure 4 and Figure 5 The power supply bracket 101 includes a switching bin 111, and the switching bin 111 is formed with a storage cavity 1110 with an opening on one side. The turntable 210 is stored in the storage cavity 1110, and the turntable 210 is rotatably connected with the switching bin 111. Specifically, the bin bottom wall 1111 of the switching bin 111 is convexly provided with a first boss 112, and the turntable 210 is rotatably sleeved on the first boss 112. The turntable 210, the inner peripheral wall of the switching bin 111, and the rotating cover 220 jointly enclose the above-mentioned installation cavity for installing the atomizer 1000. It can be understood that in other embodiments of the present application, the rotational connection can also be formed by the outer peripheral wall of the turntable 210 and the inner peripheral wall of the switching bin 111 being rotatably sleeved. At this time, since the turntable 210 has an outer peripheral wall, the installation cavity is formed by the turntable 210 and the rotating cover 220.

[0055] In one embodiment, see Figures 4 to 9The turntable 210 includes a support plate 211, a first cylinder 212 and a plurality of first partitions 213. The support plate 211 is supported on the bottom wall 1111 of the switching bin 111. The first partitions 213 are sequentially spaced along the circumference of the support plate 211. The first cylinder 212 is located at the center of the first partitions 213. One end of each first partition 213 is connected to the outer circumferential wall of the first cylinder 212. The first cylinder 212 is rotatably sleeved on the first boss 112. The rotating cover 220 is supported on the first partitions 213. The rotating cover 220, the support plate 211 and the first partitions 213 are enclosed together to form a plurality of compartments 260. Each compartment 260 is used to accommodate an atomizer 1000. The support plate 211 can support each atomizer 1000 and drive each atomizer 1000 to rotate when rotating. The first partition 213 can separate each atomizer 1000, which can not only reduce the cross-flavor, but also limit the atomizer 1000 circumferentially through the first partition 213, and drive each atomizer 1000 to rotate through the first partition 213. The first cylinder 212 can realize the rotation connection between the turntable 210 and the switching chamber 111.

[0056] In one embodiment, see Figure 5 and Figure 6 A first convex ring 214 is convexly provided on one side of the bottom wall of the support plate 211 facing the switching chamber 111, and an annular groove 113 is formed in the bottom wall of the switching chamber 111. The first convex ring 214 is inserted into the annular groove 113, and the outer peripheral wall of the first convex ring 214 is rotatably sleeved with the inner peripheral wall of the annular groove 113. The arrangement of the first convex ring 214 and the annular groove 113 can improve the rotation stability of the rotating disk 210 in the switching chamber 111.

[0057] In one embodiment, see Figure 4A plurality of circumferentially spaced limiting grooves 2141 are formed on the outer circumferential wall of the first convex ring 214, and an elastic arm 114 is formed on the bottom wall of the switching chamber 111. A limiting protrusion 1141 is formed on the elastic arm 114, and the limiting protrusion 1141 extends from the inner circumferential wall of the annular groove 113 to the annular groove 113. When the rotating disk 210 rotates relative to the switching chamber 111, the limiting protrusion 1141 is sequentially inserted into each limiting groove 2141, thereby forming a circumferential limit on the rotation of the rotating disk 210. Specifically, in the initial state, the limiting protrusion 1141 is inserted into one of the limiting grooves 2141, so that the turntable 210 is stably installed in the switching bin 111. At this time, one of the atomizers 1000 is in the use position P; when the user drives the rotating cover 220 and the turntable 210 to rotate a preset angle relative to the switching bin 111, the turntable 210 drives the next atomizer 1000 to rotate to the use position P, and the limiting protrusion 1141 is also separated from one of the limiting grooves 2141 and inserted into the next limiting groove 2141 to ensure the stability of the use of the next atomizer 1000. Among them, the setting of the limiting protrusion 1141 and the limiting groove 2141 can not only limit the circumferential position of the turntable 210 once every rotation of a preset angle, but also play the role of stopping the connection to prompt the user to rotate to the right position, and can ensure that each atomizer 1000 in the use position P is stably installed during use. It can be understood that in other embodiments of the present application, the above-mentioned limiting groove 2141 can also be formed on the inner wall of the annular groove 113, and the above-mentioned limiting protrusion 1141 can also be formed on the outer wall of the first protruding ring 214; in addition, the number of limiting grooves 2141 can also be the same as the number of limiting protrusions 1141.

[0058] In one embodiment, see Figure 5 The elastic arm 114 is a section of the inner wall of the annular groove 113 . The bottom wall of the switching chamber 111 is formed with a through groove 115 that penetrates inside and outside, and the through groove 115 is arranged around the elastic arm 114 . The arrangement of the through groove 115 can enhance the elasticity of the elastic arm 114 .

[0059] In one embodiment, see Fig. 9The first boss 112 includes a first boss 1121 and a second boss 1122 connected along the axial direction of the turntable 210, the first boss 1121 is connected to the bottom wall 1111 of the switching bin 111, the second boss 1122 is connected to the first boss 1121, the outer diameter of the first boss 1121 is greater than the outer diameter of the second boss 1122, and a first step surface 1123 is connected between the outer peripheral wall of the first boss 1121 and the outer peripheral wall of the second boss 1122. The first cylinder 212 is sleeved outside the second protrusion 1122. The first cylinder 212 has a first limit surface and a second limit surface arranged opposite to each other along the axial direction. The first limit surface abuts against the first step surface 1123. A limit member 250 is installed on the side of the second protrusion 1122 away from the first protrusion 1121. The limit member 250 abuts against the second limit surface of the first cylinder 212, so that the axial direction of the first cylinder 212 is limited by the first step surface 1123 and the limit member 250, thereby ensuring the rotation stability of the turntable 210 in the switching chamber 111.

[0060] For details, please refer to Fig. 9 The limiting member 250 includes a first limiting portion 251 and a second limiting portion 252 connected in the axial direction, and the outer diameter of the first limiting portion 251 is larger than the outer diameter of the second limiting portion 252. The inner circumferential wall of the first cylinder 212 is convexly provided with a flange 2121, and the second limiting surface is located on the flange 2121. The second limiting portion 252 is inserted into the second convex portion 1122 by interference, and the second limiting portion 252 abuts against the second limiting surface of the flange 2121. The end surface of the second limiting portion 252 away from the first limiting portion 251 is flush with the end surface of the first cylinder 212 away from the first step surface 1123. In this way, the first cylinder 212 can be axially limited by the limiting member 250, and the limiting member 250 will not protrude from the first cylinder 212. It can be understood that in other embodiments of the present application, the first cylinder 212 can also be directly sleeved outside the first protrusion 1121, and the axial limit between the first cylinder 212 and the first protrusion 1121 can be formed by the direction of the clamping, or the first cylinder 212 can be axially limited by installing locking members such as screws or bolts on the second protrusion 1122. This is not a sole limitation here.

[0061] In one embodiment, see Figure 6 , Fig. 9 and Fig.10The rotating cover 220 includes a cover plate 221, a second cylinder 222, a surrounding plate 223 and a plurality of second partitions 224. The second cylinder 222 is protruded from the center position of the side of the cover plate 221 facing the turntable 210. The surrounding plate 223 is formed at the peripheral position of the edge of the side of the cover plate 221 facing the turntable 210. The second partitions 224 are respectively formed on the side of the cover plate 221 facing the turntable 210 and are arranged in sequence along the circumferential direction. One end of each second partition 224 is respectively connected to the surrounding plate 223, and the other end of each second partition 224 is respectively connected to the turntable 210. After assembly, the cover plate 221 and the support plate 211 are arranged opposite to each other along the axial direction of the turntable 210, each first partition plate 213 and each second partition plate 224 are arranged in abutment with each other in a one-to-one correspondence, the first cylinder 212 and the second cylinder 222 are arranged opposite to each other, and the enclosure 223 can not only block and limit the outer periphery of one end of the opening of the switching bin 111 corresponding to each atomizer 1000, but also be used for the user to hold, so as to drive the entire rotating cover 220 and the turntable 210 to rotate by rotating the enclosure 223.

[0062] In one embodiment, see Figure 6 and Figure 7 Two relatively spaced stoppers 2131 are protruded from one side of the first partition 213 toward the second partition 224, and a slot 2132 is formed between the two stoppers 2131. When the second partition 224 abuts against the first partition 213, the second partition 224 is interference-fitted into the slot 2132. In this way, not only can the rotating cover 220 drive the turntable 210 to rotate together when rotating, but the rotating cover 220 and the turntable 210 are also detachable, which is convenient for replacing the atomizer 1000.

[0063] Specifically, two stoppers 2131 are formed at the periphery of the first partition 213 . When the second partitions 224 are respectively in contact with the first partitions 213 , the peripheries of the second partitions 224 are respectively inserted into the slots 2132 on the first partitions 213 .

[0064] In addition, in order to improve the connection stability between the rotating disk 210 and the rotating cover 220, the rotating disk 210 and the rotating cover 220 are also fixed by the direction of magnetic adsorption. Fig. 9 The first cylinder 212 is provided with a first magnetic member 230, and the second cylinder 222 is provided with a second magnetic member 240. When the first partition 213 and the second partition 224 are in contact with each other, the first magnetic member 230 in the first cylinder 212 and the second magnetic member 240 in the second cylinder 222 are in contact with each other, thereby adsorbing and fixing the turntable 210 and the rotating cover 220. In addition, please refer to Fig. 9In order to simplify the structure, the limit member 250 can be set as the first magnetic member 230, that is, the limit member 250 used for axially limiting the first cylinder 212 is made of magnetic material. In other words, the first magnetic member 230 used to achieve the adsorption and fixation of the turntable 210 and the rotating cover 220 is used to axially limit the first cylinder 212, thereby omitting the structural cost and occupied position of a limit member 250.

[0065] In this embodiment, the turntable 210 and the rotating cover 220 can be firmly fixed and can rotate synchronously through the interference fit between the second partition plate 224 and the slot 2132, and the magnetic adsorption between the first magnetic member 230 and the second magnetic member 240. It can be understood that in other embodiments of the present application, the turntable 210 and the rotating cover 220 can also be detachably connected in other directions, for example, by providing a hook on the second disk and a slot on the first disk, and by the engagement of the hook and the slot, not only a detachable connection can be formed, but also the turntable 210 and the rotating cover 220 can be rotated synchronously.

[0066] In one embodiment, see Figures 6 to 8 , corresponding to each first baffle 213, both of the two stoppers 2131 have extension plates 2133 extending in the direction of the support plate 211, and corresponding to each cavity 260, two extension plates 2133 are arranged along the middle, and a block 2134 is convexly arranged at one end of each extension plate 2133 away from the baffle. Correspondingly, two card slots 1101 are formed on each atomizer 1000. When the atomizer 1000 is inserted into the cavity 260 along the axial direction of the rotating disk 210, the two card blocks 2134 in the cavity 260 are elastically inserted into the two card slots 1101 of the atomizer 1000, so that the atomizer 1000 can be limited in the cavity 260, ensuring that the atomizer 1000 can rotate with the rotating disk 210 during the rotation of the rotating disk 210, and preventing the atomizer 1000 from falling out of the rotating disk 210.

[0067] In one embodiment, the extension plate 2133 and the first partition plate 213 are arranged at an obtuse angle to each other, and the extension plate 2133 is arranged to be attached to the outer wall of the atomizer 1000, and the first partition plate 213 is attached to the outer wall of the atomizer 1000. That is, the atomizer 1000 is limited in the compartment 260 by the abutment and limiting action of the two extension plates 2133 and the two first partition plates 213, and at the same time, it is also ensured that the atomizer 1000 in a working state can maintain stable air intake, stable air outlet and stable electrical connection.

[0068] For details, please refer to Figure 4 and Figure 8The atomizer 1000 has a first outer wall 1104 and a second outer wall 1105 which are arranged oppositely along the axial direction of the rotating disk 210, and the first outer wall 1104 is used to support the support plate 211 of the rotating disk 210. The atomizer 1000 also has a third outer wall 1106, a fourth outer wall 1107, two fifth outer walls 1108 and two sixth outer walls 1109 located between the first outer wall 1104 and the second outer wall 1105, and the third outer wall 1106 and the fourth outer wall 1107 are arranged oppositely along the radial direction of the rotating disk 210, and the third outer wall 1106 is arranged in an arc shape and is arranged in contact with the outer peripheral wall of the first disk, and the fourth outer wall 1107 is in an arc shape, and the fourth outer wall 1107 is arranged in contact with the bin side wall 1112 of the switching bin 111. The two fifth outer side walls 1108 are arranged opposite to each other and connected to the opposite sides of the third outer side wall 1106. The two fifth outer side walls 1108 are respectively arranged in abutment with two adjacent first partitions 213. The two sixth outer side walls 1109 are arranged opposite to each other. The sixth outer side walls 1109 are connected between the fifth outer side wall 1108 and the fourth outer side wall 1107. The two sixth outer side walls 1109 are respectively arranged in abutment with the two extension plates 2133. In this way, the atomizer 1000 can be limited around one circumference to ensure the assembly stability of the atomizer 1000 in the compartment.

[0069] In one embodiment, see Figure 5 , the switching bin 111 includes a bin bottom wall 1111 and a bin side wall 1112, and the switching bin 111 has a limiting wall 1113 radially extending outward at the position corresponding to the bin opening, and a second step surface 1114 is connected between the limiting wall 1113 and the bin side wall 1112. During assembly, each second partition 224 of the rotating cover 220 abuts and is clamped in each first partition 213, and the enclosure 223 of the rotating cover 220 is inserted into the inner side of the limiting wall 1113, and the enclosure 223 is covered on the top outside of each atomizer 1000. The setting of the limiting wall 1113 can limit the enclosure 223. In addition, the limiting wall 1113 is formed with notches on the opposite sides corresponding to the first direction X, and the user can hold the enclosure 223 with his fingers on the opposite sides of the enclosure 223 along the first direction X to hold the enclosure 223, so as to facilitate the user to drive the rotating cover 220.

[0070] In one embodiment, see Figure 1 , the outer diameter of the rotating cover 220 is less than or equal to the width dimension of the power supply bracket 101 along the first direction X, so that the rotating cover 220 can be prevented from protruding from the power supply bracket 101 along the first direction X. It can be understood that in other embodiments, the outer diameter of the rotating cover 220 can also be greater than the width dimension of the power supply bracket 101 along the first direction X, which is not the only limitation here.

[0071] In one embodiment, see Figure 1The outer end surface of the rotating cover 220 along the axial direction is flush with the outer side surface of the power supply bracket 101 along the axial direction of the rotating cover 220, so that the rotating cover 220 is prevented from protruding from the power supply bracket 101 along the axial direction. Combined with the above-mentioned notch, it can ensure that it is easy to hold without protruding.

[0072] In one embodiment, see Fig.10 , the outer peripheral wall of the enclosure 223 of the rotating cover 220 is formed with a plurality of long first grooves 2231, and each first groove 2231 is sequentially arranged at intervals along the circumference of the enclosure 223. Among them, the arrangement of the first grooves 2231 can increase the friction of the enclosure 223, so that the user can save effort when rotating the rotating cover 220. It can be understood that in other embodiments of the present application, the first grooves 2231 can also be in other shapes, such as diamond, square or circle, etc., or wave stripes can be formed on the enclosure 223, which is not limited here.

[0073] In the present application, the atomizer 1000 in the use position P needs to ensure smooth air intake and air outlet, and also needs to ensure that the atomizer 1000 is electrically connected to the power supply assembly 100, so that the atomizer 1000 can atomize normally. The air intake, air outlet and electrical connection of the atomizer 1000 in the use position P are described in turn below.

[0074] First, the air intake of the atomizer 1000 is described. In one embodiment, refer to Fig.11 There is an airflow gap 600 between the rotating frame 200 and the power supply assembly 100 for external airflow to enter the atomizer 1000. The setting of the airflow gap 600 enables the air inlet 1102 of the atomizer 1000 stored in the installation cavity to be connected with the external airflow, thereby ensuring smooth air intake of the atomizer 1000 in the use position P.

[0075] Specifically, the airflow gap 600 is formed between the enclosure 223 of the rotating cover 220 and the second step surface 1114 of the power supply assembly 100. When the rotating cover 220 is sleeved on the outside of each atomizer 1000, since the second partition 224 of the rotating cover 220 and the first partition 213 of the rotating disk 210 are arranged in a one-to-one correspondence, the rotating cover 220 can be supported to a certain height, so that the airflow gap 600 is formed between the enclosure 223 of the rotating cover 220 and the second step surface 1114, and the external airflow enters each compartment 260 from the airflow gap 600, so that the atomizer 1000 in each compartment 260 is in a smooth air intake state.

[0076] In one embodiment, see Fig.11 and Fig.12When the atomizer 1000 is assembled in the compartment 260, there is a first gap 700 between the atomizer 1000 and the enclosure 223, the first gap 700 is connected to the airflow gap 600, there is a second gap 800 between the atomizer 1000 and the cover plate 221, there is a third gap 900 between the atomizer 1000 and the second cylinder 222, and a connecting groove 1103 connected to the air inlet 1102 is formed on the outer wall of the atomizer 1000, and the connecting groove 1103 is connected to the third gap 900. When the user draws on the nozzle 300, the external airflow enters the air inlet 1102 through the airflow gap 600, the first gap 700, the second gap 800, the third gap 900 and the connecting groove 1103 in sequence, thereby ensuring smooth air intake of the atomizer 1000.

[0077] Specifically, the fourth outer side wall 1107 of the atomizer 1000 and the surrounding plate 223 are spaced apart to form a first gap 700 , and a second gap 800 is defined between the second outer side wall 1105 of the atomizer 1000 and the cover plate 221 .

[0078] In addition, the outer diameter of the second cylinder 222 is smaller than the outer diameter of the first cylinder 212 , and a third gap 900 is formed between the first cylinder 212 and the third outer side wall 1106 of the atomizer 1000 .

[0079] In one embodiment, see Fig.11 and Fig.12 The connection groove 1103 extends along the axial direction of the rotating disk 210 and is in the shape of a long strip. The arrangement of the connection groove 1103 allows the airflow in the third gap 900 to quickly enter the atomizer 1000.

[0080] In this embodiment, an airflow gap 600 is provided around the rotating frame 200 and the power supply assembly 100 so that each atomizer 1000 is in an air intake connection state. It can be understood that in other embodiments of the present application, an air intake hole for external airflow to enter the atomizer 1000 can also be formed on the power supply assembly 100 or the rotating frame 200, and the external airflow is introduced into the atomizer 1000 through the air intake hole. Among them, the rotating frame 200 can be provided with an air intake hole on the cover plate 221 or the enclosure plate 223.

[0081] In addition, the power supply assembly 100 may be provided with an air inlet on the bottom wall 1111 or the side wall 1112 of the switching chamber 111. Since the switching chamber 111 is in a stationary state relative to the use station P, an air inlet may be provided at the position of the switching chamber 111 corresponding to the atomizer 1000 at the use station P, so that only the atomizer 1000 at the use station P can be connected to the external atmosphere. Alternatively, an air inlet may be provided at the position of the switching chamber 111 corresponding to each compartment 260, so that each atomizer 1000 can maintain an air inlet connection state.

[0082] The gas outlet state of the atomizer 1000 will now be described.

[0083] In one embodiment, see Figure 3 The nozzle 300 has an air outlet 311, and the air outlet 311 is configured to communicate with the air flow channel 1300 of the atomizer 1000 rotated to the use position P. That is, only the atomizer 1000 in the use position P can maintain air outlet communication, and the user can rotate the atomizer 1000 to be used to the use position P by rotating the rotating frame 200, so that the air outlet of the atomizer 1000 is connected.

[0084] In one embodiment, see Fig.13 The power supply assembly 100 includes an air outlet seal 400, which is elastically abutted between the suction nozzle 300 and the atomizer 1000, and has a first connection port 410, which is connected between the air outlet 311 and the air flow channel 1300 of the atomizer 1000 at the use station P. The provision of the air outlet seal 400 can ensure a sealed connection between the suction nozzle 300 and the atomizer 1000.

[0085] In one embodiment, see Fig.13 The power supply assembly 100 includes a power supply bracket 101, and the power supply bracket 101 includes a switching chamber 111. The nozzle 300 includes a central tube 310, and an air outlet 311 is formed in the central tube 310. A mounting port 1118 is formed on the switching chamber 111, and an air outlet seal 400 is arranged through the mounting port 1118, and the air outlet seal 400 abuts between the atomizer 1000 and the central tube 310.

[0086] In one embodiment, see Figures 13 to 15 The outlet seal 400 includes an abutment plate 420 and a second convex ring 430 formed on one side of the abutment plate 420. The first connection port 410 sequentially penetrates the abutment plate 420 and the second convex ring 430. A first mounting groove 421 is formed inwardly on one side of the abutment plate 420 away from the second convex ring 430. The inner side surface of the first mounting groove 421 away from the second convex ring 430 is a plane. After assembly, the second convex ring 430 is interference-pierced in the mounting opening 1118, and one end of the second convex ring 430 facing away from the abutment plate 420 abuts on the atomizer 1000, and the second convex ring 430 is arranged around the airflow channel 1300, and the side of the abutment plate 420 facing the second convex ring 430 abuts on the bin side wall 1112 of the switching bin 111, and one end of the center tube 310 is received in the first mounting groove 421 and abuts on the inner side surface of the first mounting groove 421 facing away from the second convex ring 430.

[0087] In one embodiment, see Fig.14 and Fig.15The abutment plate 420 is U-shaped, and the first mounting groove 421 is also U-shaped. During assembly, the central tube 310 of the suction nozzle 300 can be slidably inserted into the first mounting groove 421 from the opening of the first mounting groove 421 .

[0088] A second mounting groove 1115 is formed inwardly on the side wall 1112 of the switching bin 111 at a position corresponding to the first connecting port 410. The bottom surface of the second mounting groove 1115 is a plane. The second mounting groove 1115 extends upward from the outer circumference of the switching bin 111 near the bottom to the position of the first connecting port 410. The abutment plate 420 is received in the second mounting groove 1115. The surface of the abutment plate 420 facing the second convex ring 430 abuts against the bottom surface of the second mounting groove 1115. In this way, the airtight seal 400 and the switching bin 111 can be in plane abutment with each other, thereby ensuring the assembly sealing.

[0089] In another embodiment of the present application, the air outlet 311 of the nozzle 300 may also be connected to the air flow channel 1300 of each atomizer 1000, so that each atomizer 1000 can ensure smooth air outlet regardless of the position.

[0090] Specifically, the air outlet seal 400 can be arranged around the side wall 1112 of the switching chamber 111, and the air outlet seal 400 is provided with a first connection port 410 corresponding to the position of each atomizer 1000, and each first connection port 410 is respectively connected to the air flow channel 1300 of each atomizer 1000. In addition, the air outlet seal 400 is formed with a second connection port respectively connected to each first connection port 410, and the second connection port is connected to the air outlet 311 of the suction nozzle 300. The above arrangement ensures that each atomizer 1000 remains connected to the suction nozzle 300 after the rotating frame 200 rotates to a preset angle each time, that is, each atomizer 1000 rotates to a certain position each time, that is, each atomizer 1000 maintains smooth air outlet.

[0091] Specifically, the abutment plate 420 of the air outlet seal 400 is attached to the outer wall of the switching chamber 111, and a plurality of second convex rings 430 are provided on the abutment plate 420. Each second convex ring 430 passes through each mounting opening 1118 along the circumferential direction of the switching chamber 111, and each second convex ring 430 abuts against the position of the air flow channel 1300 corresponding to each atomizer 1000.

[0092] It is understandable that in other embodiments, the nozzle 300 may be arranged to be covered on a peripheral outer wall of the switching chamber 111 , so that the air outlet 311 of the nozzle 300 can be connected to the air flow channel 1300 of each atomizer 1000 .

[0093] The electrical connection of the atomizer 1000 will now be described.

[0094] In one embodiment, see Fig.15 and Fig.16 The power supply assembly 100 includes an electrode 130, and the electrode 130 is configured to be electrically connected to the atomizer 1000 rotated to the use position P. That is, the power supply assembly 100 can supply power to the atomizer 1000 in the use position P through the electrode 130, so that the atomizer 1000 can heat the atomization medium inside it to form an aerosol, and the external airflow carries the aerosol out through the airflow channel 1300 of the atomizer 1000, and overflows through the air outlet 311 of the mouthpiece 300 for the user to inhale.

[0095] In one embodiment, see Figure 3 The power supply assembly 100 further includes a power supply bracket 101, a battery 140 and a circuit board 150. The battery 140 is electrically connected to the circuit board 150. The electrode 130 is electrically connected to the circuit board 150 through a wire. The electrode 130 is mounted on the power supply bracket 101. When the electrode 130 is electrically connected to the atomizer 1000, the battery 140 supplies power to the atomizer 1000 through the electrode 130, so that the atomizer 1000 heats the atomization medium to atomize the aerosol.

[0096] In one embodiment, see Figure 3 The upper bracket 110 and the lower bracket 120 are buckled together along the axial direction of the rotating frame 200 to form a battery cavity 160. The battery 140 and the circuit board 150 are both installed in the battery cavity 160. The upper bracket 110 is concave on one side away from the lower bracket 120 to form a switching chamber 111. Each atomizer 1000 and the rotating frame 200 are installed in the switching chamber 111, and the battery cavity 160 is arranged around the switching chamber 111. One end of the upper bracket 110 and the lower bracket 120 are jointly enclosed to form a mounting port 1118 that is connected to the battery 140 chamber, and the suction nozzle 300 is installed at the mounting port 1118. The electrode 130 is arranged to penetrate the chamber side wall 1112 of the switching chamber 111. One end of the electrode 130 is electrically connected to the circuit board 150 through a wire, and the other end of the electrode 130 is used to elastically abut against the conductive column 1200 of the atomizer 1000.

[0097] In one embodiment, see Fig.15 The power supply assembly 100 includes a set of electrodes 130, and the set of electrodes 130 includes two electrodes 130, and the two electrodes 130 are respectively positive and negative electrodes 130. The atomizer 1000 includes two conductive pillars 1200, and the two electrodes 130 are respectively abutted against the two positive and negative conductive pillars 1200 of the atomizer 1000. The two electrodes 130 are arranged in parallel and spaced apart, and the two electrodes 130 are respectively arranged close to the central tube 310 of the nozzle 300, so that the atomizer 1000 in the use position P can form a gas outlet connection and electrical connection together.

[0098] In one embodiment, see Fig.15 The electrode 130 is an elastic electrode column, an electrode hole is formed on the switching chamber 111, the inner wall of the switching chamber 111 is recessed with a second groove 1116, the outer wall of the switching chamber 111 is convexly provided with a second boss 1117, the second groove 1116 has a first fitting surface 11161, the second boss 1117 has a second fitting surface 11171, the electrode hole passes through the first fitting surface 11161 and the second fitting surface 11171, the first fitting surface 11161 and the second fitting surface 11171 are arranged parallel to and spaced apart from each other along the axial direction of the electrode 130, and the first fitting surface 11161 and the second fitting surface 11171 are both perpendicular to the axial direction of the electrode 130. The electrode 130 is provided with a first limiting ring 131 protruding in the radial direction, and the first limiting ring 131 is received in the second groove 1116, and the surface of the first limiting ring 131 facing the first fitting surface 11161 is arranged to fit with the plane of the first fitting surface 11161. Among them, the arrangement of the first fitting surface 11161 and the second fitting surface 11171 can improve the installation accuracy of the electrode 130 on the switching chamber 111 along the axial direction of the electrode 130, and the arrangement of the second boss 1117 makes the electrode hole on the switching chamber 111 and the electrode 130 evenly fit and limit in the circumferential direction, ensuring that the electrode 130 can be stably abutted with the conductive column 1200 of the atomizer 1000.

[0099] In one embodiment, see Fig.17 The atomizer 1000 includes a main housing 1100, and the outer wall of the main housing 1100 is concave to form a third groove 1140. The bottom surface of the third groove 1140 facing the second groove 1116 is a third fitting surface 1142. The third fitting surface 1142 is arranged parallel to the second fitting surface 11171, and the third fitting surface 1142 is arranged to fit and abut against the second limiting ring 1210 on the conductive column 1200. Specifically, the axial direction of the conductive column 1200 is coaxial with the axial direction of the electrode 130, and the third fitting surface 1142 is arranged perpendicular to the axial direction of the conductive column 1200, so that the conductive column 1200 and the electrode 130 can be stably abutted along the axial direction, and the electrical connection is stable.

[0100] In another embodiment of the present application, the power supply assembly 100 may also include a plurality of groups of electrodes 130, each group of electrodes 130 being configured to be electrically connected to each atomizer 1000 in a one-to-one correspondence. The above arrangement enables each atomizer 1000 to be electrically connected to the corresponding electrode 130 after each rotation of the rotating frame 200 by a preset angle, that is, each rotation of the rotating frame 200 to a position, without switching the electrical connection state of each atomizer 1000. At this time, as long as the air flow channel 1300 of the atomizer 1000 in the use station P is connected to the air outlet 311 of the nozzle 300, only the air inlet of the atomizer 1000 in the use station P is connected, the air outlet is connected and is electrically connected to the power supply assembly 100, that is, only the atomizer 1000 in the use station P can heat the internal atomization matrix to atomize and form an aerosol. The atomizer 1000 in other positions cannot be atomized because the air outlet is not connected.

[0101] Specifically, each group of electrodes 130 is electrically connected to the circuit board 150 via a wire.

[0102] In the present application, when the atomizer 1000 is in the use position P, the air inlet 1102 of the atomizer 1000 is connected to the external atmosphere, the air flow channel 1300 of the atomizer 1000 is connected to the air outlet 311 of the nozzle 300, and the conductive column 1200 of the atomizer 1000 is electrically connected to the power supply assembly 100. In addition, the atomizer 1000 needs to be started, that is, the power supply assembly 100 starts to supply power to the atomizer 1000 through the electrode 130.

[0103] Specifically, in one embodiment, see Fig. 9 A first boss 112 is protrudingly provided at the center position of the installation cavity corresponding to the power supply assembly 100. An airflow sensor 170 is accommodated in the first boss 112. The airflow sensor 170 is configured to communicate with the air inlet 1102 of the atomizer 1000 rotated to the use position P.

[0104] When the user draws suction from the nozzle 300, the external atmosphere enters the atomizer 1000 through the air inlet 1102 of the atomizer 1000. Since the airflow sensor 170 is connected to the air inlet 1102, the airflow sensor 170 can detect the negative pressure. The airflow sensor 170 feeds back the detection result to the circuit board 150. The circuit board 150 starts to power the atomizer 1000 through the electrode 130. The atomizer 1000 heats the atomizing medium inside it and atomizes it to form an aerosol. The external airflow enters the airflow channel 1300 through the air inlet 1102 to carry the aerosol out of the air, and finally flows out through the air outlet 311 of the nozzle 300.

[0105] In this embodiment, by installing the airflow sensor 170 at the center of the installation cavity, it is convenient to connect the airflow sensor 170 with the air inlet 1102 of the atomizer 1000. It not only has a simple structure, but also can utilize the position of the first boss 112, thereby reducing the space occupied by the airflow sensor 170.

[0106] In one embodiment, see Fig. 9 A receiving chamber 1124 is formed at the center of the first convex portion 1121. The receiving chamber 1124 is formed by being recessed from the bottom outer side of the switching chamber 111 to the first convex portion 1121. A sealing sleeve 180 is interference-fitted in the receiving chamber 1124. The airflow sensor 170 is installed in the sealing sleeve 180. The sealing sleeve 180 is formed with a receiving chamber 181 and a negative pressure hole 182. The airflow sensor 170 is installed in the receiving chamber 181. The negative pressure hole 182 is communicated with the receiving chamber 181. The negative pressure hole 182 is communicated with the air inlet 1102 of the atomizer 1000.

[0107] In one embodiment, the accommodating cavity 1124 penetrates part of the side wall of the first protrusion 1121 to form a gap, and the sealing sleeve 180 partially extends from the gap to seal against the atomizer 1000, thereby forming a sealed connection between the negative pressure hole 182 and the air inlet 1102.

[0108] In one embodiment, see Fig. 9 A connecting cavity 1120 is formed inside the atomizer 1000, and an air inlet 1102 and a negative pressure connecting port 1130 are formed on the side wall of the atomizer 1000. The air inlet 1102 and the negative pressure connecting port 1130 are both connected to the connecting cavity 1120, and the connecting cavity 1120 is connected to the air flow channel 1300. When the sealing sleeve 180 abuts against the outer wall of the atomizer 1000, the negative pressure hole 182 is connected to the negative pressure connecting port 1130, and the negative pressure hole 182 is connected to the air inlet 1102 through the negative pressure connecting port 1130 and the connecting cavity 1120, and the external airflow enters the air flow channel 1300 from the air inlet 1102 via the connecting cavity 1120, so that the airflow sensor 170 can detect the airflow flowing through the connecting cavity 1120.

[0109] In other embodiments of the present application, the airflow sensor 170 may not be formed on the first boss 112 , but a negative pressure channel connecting the air outlet 311 of the suction nozzle 300 and the airflow sensor 170 may be directly formed on the power supply bracket 101 , which is not a sole limitation here.

[0110] In one embodiment, see Figure 3The circuit board 150 is provided with an indicator light 152, and the power supply bracket 101 forms a light channel 1161 at a position corresponding to the indicator light 152. When the electrode 130 supplies power to the atomizer 1000, that is, when the atomizer 1000 is started, the indicator light 152 is on, and the light of the indicator light 152 is guided out through the light channel 1161 to prompt the user.

[0111] In one embodiment, see Figure 3 The power bracket 101 extends a light guide plate 116 toward the circuit board 150 , and a light guide channel 1161 passes through the light guide plate 116 . The light guide plate 116 abuts against the circuit board 150 , and the indicator light 152 is inserted into the light guide channel 1161 , thereby achieving light guiding.

[0112] In one embodiment, see Figure 3 The upper bracket 110 has a first limiting rib 117 extending toward the lower bracket 120 , and the lower bracket 120 has a second limiting rib 121 extending toward the upper bracket 110 . The first limiting rib 117 and the second limiting rib 121 respectively cover and limit the battery 140 on opposite sides, thereby limiting the battery 140 in the battery cavity 160 .

[0113] In one embodiment, see Figure 3 The upper bracket 110 has support ribs 118 extending toward the lower bracket 120. The upper bracket 110 is also provided with positioning posts (not shown) along the direction of the lower bracket 120. The circuit board 150 is supported on the support ribs 118 and the positioning posts, and the circuit board 150 is locked on the positioning posts by fasteners such as screws.

[0114] In one embodiment, see Figure 3 A charging seat 151 is also provided on the circuit board 150 , and a charging port is formed together at one end of the upper bracket 110 and the lower bracket 120 away from the suction nozzle 300 . The user can connect the power cord to the charging seat 151 through the charging port to charge the battery 140 .

[0115] In one embodiment, see Figure 3The suction nozzle 300 also includes an outer tube 320, one end of which is integrally connected to the central tube 310, and the other end of the outer tube 320 extends outward with a convex edge 330, and the inner side wall of the upper bracket 110 is formed with a first limiting opening 119, and the inner side wall of the lower bracket 120 is formed with a second limiting opening 122. During assembly, the suction nozzle 300 can be first installed on the upper bracket 110, and the convex edge 330 of the suction nozzle 300 is correspondingly inserted into the first limiting opening 119 of the upper bracket 110, and the suction nozzle 300 is abutted against the bottom surface of the first mounting groove 421, and then the lower bracket 120 is buckled along the axial direction of the rotating frame 200 toward the upper bracket 110, so that the second limiting opening 122 on the lower bracket 120 just buckles the corresponding convex edge 330 of the outer tube 320, thereby realizing the assembly of the suction nozzle 300, the upper bracket 110 and the lower bracket 120.

[0116] On the other hand, the present application also provides an aerosol generating device, including a plurality of atomizers 1000 and the above-mentioned atomizing apparatus, at least one atomizer 1000 is arranged in the atomizing apparatus. The aerosol generating device can carry a plurality of atomizers 1000 and atomizers 1000 of different flavors through the arrangement of the above-mentioned atomizing apparatus, so as to meet the large suction needs and multi-flavor requirements of different users. When in use, one or more atomizers 1000 can be arranged in the atomizing apparatus.

[0117] In one embodiment, see Figure 2 Each atomizer 1000 is separately provided, that is, each atomizer 1000 is independently assembled, and each atomizer 1000 is respectively assembled in each compartment 260 in the rotating frame 200.

[0118] In another embodiment of the present application, each atomizer 1000 may be integrally connected, for example, the main shell 1100 of each atomizer 1000 may be integrally connected, so that each atomizer 1000 can be assembled and transported together, but each atomizer 1000 operates independently.

[0119] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
