DETAILED DESCRIPTION

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] As mentioned in the background technology, due to the limited capacity of the atomizer, a single atomizer cannot meet the user's puffing needs. At the same time, in order to meet the user's demand for multiple flavors, atomizers that can carry multiple atomizers have appeared on the market. However, for those users who have a large demand for one-time puffing and are impatient to frequently change atomizers, this type of atomizer will lead to a poor user experience.

[0045] In order to solve the above problems, the embodiments of the present application provide a nebulizer 1000 and an aerosol generating device. By providing a nebulizer 1000 that can replace multiple nebulizer units 2000 and be accommodated in a nebulizer device, the capacity of the nebulizer 1000 can be larger than the nebulizer unit 2000, thereby being able to meet the needs of users with a large demand for one-time inhalation, and there is no need to frequently replace the nebulizer 1000, thereby improving the user experience.

[0046] It should be noted here that both the atomizer 1000 and the atomizing unit 2000 are atomizing structures that contain atomizing medium and can heat and atomize the atomizing medium to form an aerosol and derive it after power is turned on. Regarding the appearance structure, the appearance profile of a single atomizer 1000 is equivalent to the overall appearance profile of multiple atomizing units 2000. For example, the appearance profile of a single atomizer 1000 is equivalent to the overall appearance profile of two, three, four or more atomizing units 2000. Regarding the capacity of the atomizing medium, the atomizing medium capacity of a single atomizer 1000 is several times the atomizing medium capacity in a single atomizing unit 2000, such as 2 times, 2.5 times, 3 times, 4 times or more than 4 times. Therefore, when the atomizer 1000 replaces multiple atomizing units 2000 and is accommodated in an atomizing device, the aerosol generating device can meet the needs of users with a large disposable suction demand, and there is no need to frequently replace the atomizer 1000, thereby improving the user experience.

[0047] See also Figure 1 and Figure 2 , the aerosol generating device provided in the embodiment of the present application is now described. The aerosol generating device includes an atomizing device and a plurality of atomizing units 2000, each atomizing unit 2000 is housed in the atomizing device, the atomizing device is used to supply power to each atomizing unit 2000, and the atomizing unit 2000 is used to heat the atomizing medium and atomize it to form an aerosol after power is supplied. In actual application, the user can choose to load a plurality of atomizing units 2000 of different flavors into the atomizing device for use according to his or her own preferences.

[0048] See also Figures 1 to 4 The atomizer includes an atomizer bracket 100 and an electrode assembly 200. The electrode assembly 200 includes an electrode bracket 210 and a first electrode 220 disposed on the electrode bracket 210. The first electrode 220 is electrically connected to the power supply assembly 3000. The atomizer bracket 100 is rotatably connected to the electrode bracket 210. The atomizer bracket 100 can accommodate multiple atomizer units 2000. The atomizer bracket 100 can rotate relative to the electrode bracket 210 to switch the relative position between the first electrode 220 and each atomizer unit 2000, so that only part of the atomizer units 2000 are in an electrically connected state each time. The user can choose atomizer units 2000 of different flavors according to his or her preferences, or after using one atomizer unit 2000, rotate and switch to the next atomizer unit 2000.

[0049] Specifically, the atomization unit 2000 includes a third electrode 2300 . After the atomizer bracket 100 and the electrode bracket 210 rotate relative to each other, the first electrode 220 is electrically connected to the third electrode 2300 in the corresponding atomization unit 2000 , so that the atomization unit 2000 can be powered by the power supply assembly 3000 .

[0050] In one embodiment, see Figures 4 to 6 The atomizer support 100 includes a plurality of partitions 120, each partition 120 is radially distributed with the center line of the atomizer support 100 as the center, and a socket 130 is formed between two adjacent partitions 120. The outer peripheral wall of one end of the atomizer unit 2000 facing the electrode support 210 is concave to form an air-avoiding groove 2200, so that the end of the atomizer unit 2000 facing the electrode support 210 is formed with a second convex portion 2100, and the air-avoiding groove 2200 is arranged around the second convex portion 2100. When multiple atomization units 2000 are respectively installed in the atomizer bracket 100, the second protrusion 2100 of the atomization unit 2000 and each partition 120 can guide each other so that the second protrusion 2100 of each atomization unit 2000 is correspondingly inserted into one of the sockets 130, and the avoidance groove 2200 of the atomization unit 2000 just avoids the setting of the partition 120, and the atomization unit 2000 is supported on the partition 120.

[0051] In this embodiment, the second protrusion 2100 and the partition 120 are circumferentially abutted to form a rotation limit between the atomizer bracket 100 and the atomizer unit 2000, so that the atomizer bracket 100 can rotate with each atomizer unit 2000 when rotating relative to the electrode bracket 210, thereby realizing the position switching between the first electrode 220 and each atomizer unit 2000. In addition, the arrangement of the socket 130, the partition 120, the second protrusion 2100 and the avoidance groove 2200 can guide the assembly of the atomizer unit 2000, ensuring that each atomizer unit 2000 can be correctly assembled in the atomizer bracket 100.

[0052] In one embodiment, see Figure 4 The number of partitions 120 and the number of sockets 130 are the same as the number of atomizer units 2000 that the atomizer bracket 100 can accommodate, so that each socket 130 can be used to plug and position an atomizer unit 2000, ensuring that each atomizer unit 2000 is regularly assembled in the atomizer bracket 100, and can form a rotation limit between the atomizer unit 2000 and the atomizer bracket 100, so that the atomizer bracket 100 can drive each atomizer unit 2000 to rotate together, so that the electrical connection of each atomizer unit 2000 is switched.

[0053] In a specific embodiment, see Figure 4 , the number of atomizing units 2000 is four, and the number of corresponding partitions 120 is also four, two adjacent partitions 120 are just 90 degrees to each other, and two opposite partitions 120 are just located on the same straight line, which can increase the structural strength of each partition 120. It can be understood that in other embodiments, the number of atomizing units 2000 can also be two, three, five or more than five, which is not limited here.

[0054] In one embodiment, see Fig.12 , along the axial direction of the atomization unit 2000, the height L1 of the second protrusion 2100 ranges from 6mm to 12mm. Specifically, the height L1 of the second protrusion 2100 can be 6mm, 7mm, 8mm, 9mm, 10mm, 11mm or 12mm. Among them, the height L1 of the second protrusion 2100 cannot be too high. If the height of the second protrusion 2100 is too high, secondary problems will occur, and the high height of the second protrusion 2100 will cause the third electrode 2300 to be too long, which is not conducive to assembly. The high height of the second protrusion 2100 will cause the atomization chamber of the atomization unit to be raised, which is not conducive to the aerosol export; in addition, the height of the second protrusion 2100 cannot be too short. If it is too short, the second protrusion 2100 and the partition 120 will not have an obvious assembly guiding effect on the atomization unit 2000.

[0055] In one embodiment, see Figure 6 and Figure 7 The inner wall of the atomizer bracket 100 is also provided with reinforcing bones 140, and each reinforcing bone 140 is connected to each partition 120 one by one. The arrangement of the reinforcing bones 140 can not only enhance the structural strength of the atomizer bracket 100, but also enhance the supporting strength of the partition 120 to each atomizing unit 2000.

[0056] In one embodiment, the protruding height of the reinforcing bone 140 ranges from 0.5mm to 5mm. Specifically, the protruding height of the reinforcing bone 140 can be 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm and 5.0mm. It should be noted that the protruding height here refers to the height of the inner circumferential wall of the nebulizer bracket 100 protruding from the reinforcing bone 140 along the lateral direction, and the lateral direction refers to the direction perpendicular to the axial direction of the atomizing device. In addition, it should be noted that if the height of the reinforcing bone 140 is too small, it will not play a reinforcing role. If the height of the reinforcing bone 140 is too high, it is easy to cause structural interference with the atomizing unit 2000, which is not conducive to the assembly of the atomizing unit 2000 in the atomizing unit bracket 100. In this embodiment, the height of the reinforcing bone 140 is limited to ensure that the reinforcing bone 140 can both play a reinforcing role and not affect the assembly of the atomizing unit 2000.

[0057] In one embodiment, see Figure 6 and Figure 7 The atomizer bracket 100 includes a hollow cylinder 110, each reinforcement bone 140 is protruded on the inner wall of the cylinder 110, one end of the partition 120 is vertically connected to the bottom end of the reinforcement bone 140, and the other end of each partition 120 is integrally connected at the center of the cylinder 110.

[0058] In one embodiment, see Figure 2 The atomizer device further includes a rotating shaft 900, and the atomizer bracket 100 and the electrode bracket 210 are rotationally connected via the rotating shaft 900. Specifically, one of the atomizer bracket 100 and the electrode bracket 210 is rotationally connected to the rotating shaft 900, and the other of the atomizer bracket 100 and the electrode bracket 210 is synchronously rotationally connected to the rotating shaft 900, so that the atomizer bracket 100 and the electrode bracket 210 can be rotationally connected via the rotating shaft 900.

[0059] In one embodiment, see Figure 2 , the rotating shaft 900 is connected to the electrode holder 210 in synchronous rotation, and the rotating shaft 900 is connected to the atomizer holder 100 in rotation, and the atomizer holder 100 is driven to rotate relative to the rotating shaft 900, so that the atomizer holder 100 can rotate relative to the electrode holder 210. It can be understood that in other embodiments of the present application, the rotating shaft 900 can also be connected to the atomizer holder 100 in synchronous rotation, and the rotating shaft 900 can be connected to the electrode holder 210 in rotation, so that the atomizer holder 100 and the electrode holder 210 can also rotate relative to each other.

[0060] In the present application, the rotating shaft 900 and the electrode bracket 210 can be locked and fixed to form a synchronous rotation connection, can be welded to form a synchronous rotation connection, can be snapped to form a synchronous rotation connection, or can be abutted and limited along the circumferential direction to form a synchronous rotation connection. The following is a detailed description of an embodiment.

[0061] In one embodiment, see Figure 2 , Figure 8 and Fig. 9 The electrode holder 210 is formed with a second mounting hole 217 which penetrates axially, and the first end of the rotating shaft 900 is inserted into the second mounting hole 217 by interference fit, and the first end of the rotating shaft 900 is an asymmetric structure, and the second mounting hole 217 is also an asymmetric structure, and the rotating shaft 900 is inserted into the second mounting hole 217 by interference fit, forming a fixed connection between the rotating shaft 900 and the electrode holder 210, so that the rotating shaft 900 and the electrode holder 210 rotate synchronously.

[0062] Specifically, the inner circumferential wall of the second mounting hole 217 is formed with a first plane 2171 extending along its axial direction, and the outer circumferential wall of the first end of the rotating shaft 900 is formed with a second plane 910 extending along its axial direction. When the rotating shaft 900 is inserted into the second mounting hole 217, the first plane 2171 and the second plane 910 are arranged in a close fit to form a synchronous rotation connection between the rotating shaft 900 and the electrode bracket 210.

[0063] Also, see Figure 2The locking member 4000 locks the bottom wall of the second mounting hole 217 and the first end of the rotating shaft 900 together, thereby forming an axial limit between the rotating shaft 900 and the electrode holder 210. Of course, in other embodiments, the first end of the rotating shaft 900 can also be connected to the electrode holder 210 in other ways, such as by interference fit, as long as the two are connected firmly and relatively fixed, and this is not the only limitation here.

[0064] In one embodiment, see Figure 4 An axial hole 150 is formed at the bottom center of the atomizer bracket 100 , and the rotating shaft 900 is arranged to penetrate the axial hole 150 . The atomizer bracket 100 is rotatably connected with the rotating shaft 900 through the axial hole 150 .

[0065] Specifically, the shaft hole 150 is formed at the center position where each partition plate 120 is cross-connected.

[0066] In one embodiment, see Fig. 9 and Fig.14 A card block 111 is formed on the inner wall of the atomizer bracket 100, and a card slot 212 is concavely formed on the outer surface of the electrode bracket 210, and the card slot 212 extends along the circumference of the electrode bracket 210; when the atomizer bracket 100 and the electrode bracket 210 are axially sleeved, the card block 111 is inserted into the card slot 212. When the card block 111 is inserted into the card slot 212, the atomizer bracket 100 and the electrode bracket 210 can be limited in the axial direction of the atomizer device, so as to ensure that the atomizer bracket 100 and the electrode bracket 210 are difficult to separate in the axial direction of the atomizer device while rotating relative to each other, thereby ensuring the rotation stability of the atomizer bracket 100 and the electrode bracket 210.

[0067] In the above example, see Fig.10 The outer peripheral wall of the electrode bracket 210 is convexly provided with a first convex ring 2191 and a second convex ring 2192. The first convex ring 2191 and the second convex ring 2192 are spaced along the axial direction of the atomizer to form the above-mentioned card groove 212. The card block 111 is inserted between the first convex ring 2191 and the second convex ring 2192 from the side of the first convex ring 2191 away from the second convex ring 2192. Specifically, the elasticity of the card block 111 and the first convex ring 2191 is overcome by external force, so that the card block 111 is inserted into the card groove 212, so that it can slide in the card groove 212.

[0068] For details, please refer to Fig.10The block 111 includes a first mating surface 1111 and a fourth mating surface 1112 that are arranged opposite to each other, and the slot 212 has a second mating surface 2121 and a third mating surface 2122 that are arranged opposite to each other. When the block 111 slides in the slot 212, the first mating surface 1111 abuts against the second mating surface 2121, and the third mating surface 2122 abuts against the fourth mating surface 1112.

[0069] In one embodiment, see Fig.10 The block 111 also includes a connecting surface 1113 and a first guide surface 1114. The connecting surface 1113 is arranged at a relative interval with the inner circumference of the atomizer bracket 100. One end of the connecting surface 1113 is connected to the fourth matching surface 1112. The first guide surface 1114 is connected between the other end of the connecting surface 1113 and the first matching surface 1111. The first guide surface 1114 is arranged obliquely relative to the first matching surface 1111. The surface of the first convex ring 2191 away from the second convex ring 2192 is the second guide surface 2193. The second guide surface 2193 is arranged obliquely relative to the axial direction of the atomizer. When the block 111 is in contact with the first convex ring 2191, the first guide surface 1114 and the second guide surface 2193 are arranged in a close fit. Through the guiding effect of the first guide surface 1114 and the second guide surface 2193, the block 111 can be quickly inserted into the card slot 212 from the first convex ring 2191.

[0070] In the present application, the electrical connection state between the atomizer unit 2000 and the first electrode 220 is switched by relative rotation of the atomizer bracket 100 and the electrode bracket 210. In order to facilitate the user to know whether the atomizer bracket 100 or the electrode bracket 210 is rotated to the right position when rotating the atomizer bracket 100 or the electrode bracket 210, the present embodiment designs the following scheme.

[0071] For details, please refer to Figure 3 and Figure 6 , a convex strip 112 is convexly provided on the inner wall of the atomizer bracket 100, and a plurality of matching grooves 213 spaced along the circumferential direction are concavely provided on the outer wall of the electrode bracket 210. During the relative rotation of the atomizer bracket 100 and the electrode bracket 210, the convex strip 112 is stuck in different matching grooves 213. Specifically, when the atomizer bracket 100 rotates relative to the electrode bracket 210, the convex strip 112 is disengaged from one of the matching grooves 213, and is stuck in the next matching groove 213 after the atomizer bracket 100 is rotated into place, thereby ensuring that the atomizer bracket 100 is stably assembled after being rotated into place, and will not rotate erroneously. At the same time, the clamping connection between the convex strip 112 and the matching groove 213 can produce a jam, thereby providing a prompt to the user.

[0072] The number of the matching grooves 213 can be the same as the number of the atomizer units 2000, so that when the atomizer bracket 100 rotates a preset angle, the protrusion 112 is inserted from one of the matching grooves 213 into the next matching groove 213, which can not only form a circumferential limit, but also produce a jam each time it rotates to the right position to prompt the user to rotate to the right position. Of course, in other embodiments, the number of matching grooves 213 can also be N times the number of the atomizer units 2000, that is, it rotates a preset angle after each jam N times.

[0073] The number of the convex strip 112 can be one, and the convex strip 112 is engaged with one of the matching grooves 213. Alternatively, the number of the convex strips 112 can be multiple, and it is necessary to ensure that the number of the matching grooves 213 is an integer multiple of the number of the convex strips 112, so that each convex strip 112 can be engaged with the corresponding matching groove 213.

[0074] In the above embodiment, the convex strip 112 extends along the axial direction of the electrode holder 210, and the matching groove 213 is arranged along the axial direction of the atomizer and penetrates the first convex ring 2191. When the card block 111 is inserted into the card groove 212 along the axial direction of the atomizer, the convex strip 112 is inserted into the matching groove 213. Among them, the setting of the convex strip 112 can improve the clamping stability and clamping strength between the convex strip 112 and the matching groove 213. It can be understood that in other embodiments of the present application, the convex strip 112 may not be in the shape of a long strip, but in the shape of a block or an arc, and the matching groove 213 may also be a groove or an arc groove. In addition, the matching groove 213 may also be formed on the atomizer holder 100, and the convex strip 112 may be formed on the electrode holder 210. This is not the only limitation here.

[0075] In one embodiment, see Figure 2 , Figure 3 and Figure 5 A first magnetic member 230 is installed on the electrode bracket 210, and a second magnetic member 2600 is provided in the atomization unit 2000. The first magnetic member 230 and the second magnetic member 2600 attract each other, so that the atomization unit 2000 can be attracted each time it is rotated into place to ensure the stability of the electrical connection between the first electrode 220 and the atomization unit 2000.

[0076] In one embodiment, see Figure 1 and Figure 2The atomizer also includes a nozzle 300, which is installed at one end of the atomizer bracket 100 away from the electrode bracket 210. The nozzle 300 and the electrode bracket 210 form a rotation limit connection through the rotating shaft 900, that is, the nozzle 300 and the electrode bracket 210 can rotate synchronously. In practical applications, the electrical connection switching and gas outlet switching of each atomization unit 2000 can be achieved by rotating one of the nozzle 300, the electrode bracket 210 or the atomizer bracket 100.

[0077] In one embodiment, see Figure 2 , a first mounting hole 340 is formed on the suction nozzle 300, the second end of the rotating shaft 900 is inserted into the first mounting hole 340 by interference, and the second end of the rotating shaft 900 is an asymmetric structure, the first mounting hole 340 is also an asymmetric structure, the rotating shaft 900 is inserted into the first mounting hole 340 by interference, forming a fixed connection between the rotating shaft 900 and the suction nozzle 300. And the first end of the rotating shaft 900 is inserted into the second mounting hole 217 of the electrode holder 210 by interference, forming a fixed connection between the rotating shaft 900 and the electrode holder 210, thereby ensuring that the suction nozzle 300 and the electrode holder 210 rotate synchronously. It can be understood that in other embodiments of the present application, the second end of the rotating shaft 900 can also be fixed to the suction nozzle 300 by screw locking or bonding, etc., which is not the only limitation here.

[0078] Specifically, the first mounting hole 340 has third planes that are arranged opposite to each other, and the second end of the rotating shaft 900 has a fourth plane 920 that is arranged opposite to each other. The two third planes and the two fourth planes 920 are arranged in a one-to-one correspondence and abutment with each other.

[0079] In one embodiment, see Figure 2 The nozzle 300 is formed with a first air outlet 310, and the atomizing unit 2000 is formed with a third air outlet 2500. The atomizing device further includes a nozzle seal 800, which is interference-fitted between each atomizing unit 2000 and the nozzle 300, and a first connecting port 810 is formed on the nozzle seal 800, and the first connecting port 810 is relatively connected to the third air outlet 2500. The rotating electrode bracket 210, the atomizer bracket 100 or the suction nozzle 300 can switch the relative position of the first air outlet 310 and each atomization unit 2000, so that each time only the third air outlet 2500 of the atomization unit 2000 electrically connected to the first electrode 220 is connected to the first air outlet 310 through the first connecting port 810, and the third air outlet 2500 of the atomization unit 2000 disconnected from the first electrode 220 is blocked by the suction nozzle seal 800, thereby avoiding the atomization units 2000 from odor mixing with each other.

[0080] In one embodiment, see Figure 2The suction nozzle 300 and the atomizer bracket 100 are arranged to be sleeved with each other, thereby forming a rotation connection between the suction nozzle 300 and the atomizer bracket 100.

[0081] In order to ensure the connection stability between the nozzle 300 and the atomizer bracket 100. Figure 6 and Fig.10 A first peripheral bone 360 ​​extends from the end surface of the nozzle 300 facing the atomizer bracket 100 toward the atomizer bracket 100. During assembly, the first peripheral bone 360 ​​is axially inserted into the atomizer bracket 100, and the outer peripheral wall of the first peripheral bone 360 ​​is fitted with the inner peripheral wall of the atomizer bracket 100.

[0082] In addition, a protrusion 114 is convexly provided on the inner wall of the atomizer bracket 100, and a third convex ring 330 extending in the circumferential direction is formed on the outer wall of the suction nozzle 300. When the first peripheral bone 360 ​​is inserted into the atomizer bracket 100, the protrusion 114 is inserted into the upper side surface of the third convex ring 330 from the lower side surface of the third convex ring 330 to limit the suction nozzle 300 from separating from the atomizer bracket 100 in the axial upward direction relative to the atomizer bracket 100; in addition, the end surface of the suction nozzle 300 facing the atomizer bracket 100 abuts against the end surface of the atomizer bracket 100 facing the suction nozzle 300 to limit the suction nozzle 300 from moving in the axial downward direction relative to the atomizer bracket 100, thereby realizing axial limitation of the atomizer bracket 100 and the suction nozzle 300, and further ensuring the connection stability of the atomizer bracket 100 and the suction nozzle 300.

[0083] Optionally, the number of protrusions 114 can be multiple, and each protrusion 114 is spaced along the circumference of the atomizer bracket 100, and each protrusion 114 is respectively connected with the third protruding ring 330. When disassembling, the nozzle 300 can be pulled out upward to replace the atomization unit 2000. It can be understood that in other embodiments of the present application, a card block can also be formed on the nozzle 300, and the protrusion 114 is connected with the card block, which is not limited here.

[0084] In one embodiment, see Figures 3 to 5 A first air inlet 211 is formed on the electrode bracket 210, and the atomization unit 2000 has a third air inlet 2400. The atomizer bracket 100 can rotate relative to the electrode bracket 210 to switch the relative position between the first air inlet 211 and each atomization unit 2000, thereby switching the connection state between the first air inlet 211 and each third air inlet 2400.

[0085] In one embodiment, see Figure 2 and Fig.12An air inlet seal 500 is abutted between the electrode bracket 210 and the atomizer bracket 100 , and a second connecting port 510 is formed on the air inlet seal 500 at a position corresponding to the first air inlet 211 , and the first air inlet 211 is connected to the second air inlet 1123 of the atomization unit 2000 through the second connecting port 510 .

[0086] In one embodiment, see Figures 1 to 3 and Fig.13 The atomizing device further comprises a shell 400, which is sleeved on the outside and bottom of the electrode holder 210, a fourth air inlet 410 is formed at the bottom of the shell 400, an air inlet channel 214 is formed on the electrode holder 210, the bottom end of the air inlet channel 214 is communicated with the fourth air inlet 410, and the top end of the air inlet channel 214 is communicated with the first air inlet 211, when the user draws suction from the nozzle 300, the external atmosphere enters the atomizing unit 2000 via the fourth air inlet 410, the air inlet channel 214, the first air inlet 211, the second connecting port 510 and the second air inlet 1123 in sequence.

[0087] In one embodiment, see Fig.13 A second sealing gasket 700 is abutted between the electrode support 210 and the housing 400 , and a sealed connection is formed between the fourth air inlet 410 and the air inlet passage 214 through the second sealing gasket 700 .

[0088] In one embodiment, see Fig.13 The atomizer also includes a control unit 600, which includes a circuit board 610 and an airflow sensor 620. The first electrode 220 is electrically connected to the circuit board 610, and the airflow sensor 620 is electrically connected to the circuit board 610. The airflow sensor 620 is used to sense the airflow when the user sucks on the nozzle 300 and feed it back to the circuit board 610. The circuit board 610 supplies power to the atomizer unit 2000 or the atomizer 1000 through the first electrode 220, thereby starting the atomizer unit 2000 or the atomizer 1000 to heat the liquid matrix inside it and atomize it to form an aerosol, which is finally discharged through the first air outlet 310.

[0089] In one embodiment, see Fig.12 and Fig.13 A negative pressure hole 215 is also formed on the electrode bracket 210, a sealing sleeve 630 is abutted between the circuit board 610 and the electrode bracket 210, and the airflow sensor 620 is installed in the sealing sleeve 630. The airflow sensor 620 is connected to the negative pressure hole 215 through the sealing sleeve 630. Fig.16A connecting groove 520 is formed on the side of the air intake seal 500 facing the electrode bracket 210, and the negative pressure hole 215 and the first air intake port 211 are both connected to the connecting groove 520, so that the negative pressure hole 215 is connected to the first air intake port 211, so that the airflow sensor 620 can detect the airflow flowing through the first air intake port 211.

[0090] For details, please refer to Fig.13 The electrode bracket 210 is also formed with a mounting groove 216 which is in communication with the negative pressure hole 215 , and the sealing sleeve 630 is installed in the mounting groove 216 .

[0091] In one embodiment, see Fig.13 The electrode support 210 also forms a battery cavity 218 , and the power supply assembly 3000 is accommodated in the battery cavity 218 .

[0092] In one embodiment, see Figure 6 Observation ports 115 are formed on the side walls of the atomizer bracket 100 corresponding to the positions of the atomization units 2000 , and the user can observe the usage of the atomization units 2000 at the observation ports 115 .

[0093] In the present application, the above-mentioned atomizer can not only carry multiple atomizer units 2000 for use, but also carry a single atomizer 1000 for use.

[0094] See also Figures 14 to 17 , the atomizer 1000 provided in the embodiment of the present application is now described. The atomizer 1000 is used to match the atomizing device. Specifically, the atomizer 1000 can replace multiple atomizing units 2000 and be accommodated in the atomizer bracket 100. The atomizer 1000 is configured to form a rotation limit connection with the atomizer bracket 100, and the atomizer 1000 is coaxial with the atomizer bracket 100. The atomizer 1000 includes a second electrode 1150; the atomizer bracket 100 can rotate relative to the electrode bracket 210 to switch the electrical connection state between the first electrode 220 and the second electrode 1150.

[0095] During use, the user can rotate the electrode holder 210 or the atomizer holder 100 so that the second electrode 1150 of the atomizer 1000 just contacts the first electrode 220 on the electrode holder 210 to form an electrical connection, thereby putting the atomizer 1000 in a working state. During transportation, the electrode holder 210 or the atomizer holder 100 can be rotated so that the second electrode 1150 and the first electrode 220 are staggered with each other, thereby putting the atomizer 1000 in a power-off state to avoid leakage or accidental start-up.

[0096] The capacity of the atomizer 1000 can be multiple times the capacity of the atomizer unit 2000, such as 2 times, 2.5 times or 3 times, etc., that is, the capacity of the atomizer 1000 can be set to be larger than the capacity of the atomizer unit 2000 to meet the needs of users with large one-time inhalation requirements, and there is no need to frequently replace the atomizer 1000. In addition, the user can choose to install multiple atomizer units 2000 into the atomizer according to their own usage habits, or choose to install a single atomizer 1000 into the atomizer, and there are more options to choose from.

[0097] The atomizer 1000 in the embodiment of the present application is configured to be able to replace multiple atomization units 2000 and be accommodated in the atomizer holder 100. The atomizer 1000 is configured to form a rotationally limited connection with the atomizer holder 100. The atomizer 1000 is coaxial with the atomizer holder 100, that is, the atomizer 1000 can be used with an atomization device that can carry multiple atomization units 2000. The atomizer 1000 can replace multiple atomization units 2000 and be accommodated in the atomizer holder 100, so that the capacity of the atomizer 1000 can be set to be equivalent to the capacity of multiple atomization units 2000, thereby meeting the use needs of users with greater disposable inhalation needs, and there is no need to frequently replace the atomizer 1000 during use, thereby improving user experience. In addition, the electrode holder 210 or the atomizer holder 100 can be rotated so that the second electrode 1150 of the atomizer 1000 just contacts the first electrode 220 on the electrode holder 210 to form an electrical connection, so that the atomizer 1000 is in a working state, and during transportation, the electrode holder 210 or the atomizer holder 100 can be rotated so that the second electrode 1150 and the first electrode 220 are staggered with each other, so that the atomizer 1000 is in a power-off state to avoid leakage or accidental start-up. When assembling the atomizer 1000, the atomizer 1000 can be inserted into the atomizer holder 100 in any direction on the circumference, which is convenient for assembly.

[0098] In one embodiment, see Fig.17 A through hole 1220 for the rotating shaft 900 to pass through is formed at the center of the atomizer 1000. Among them, the through hole 1220 is set, and the rotating shaft 900 can pass through the atomizer 1000 to connect the suction nozzle 300 and the electrode bracket 210, so as to realize the synchronous rotation of the suction nozzle 300 and the electrode bracket 210.

[0099] In one embodiment, see Figure 3 and Fig.15The atomizer 1000 has a second air inlet 1123 for communicating with the first air inlet 211 on the electrode holder 210, and the second air inlet 1123 and the second electrode 1150 are eccentrically arranged relative to the rotation center line of the atomizer 1000. By eccentrically arranging the second air inlet 1123 and the second electrode 1150, the air intake states of the first air inlet 211 and the second air inlet 1123, and the electrical connection state of the first electrode 220 and the second electrode 1150 can be switched simultaneously by rotating the electrode holder 210 or the atomizer holder 100.

[0100] In one embodiment, see Fig.15 , Fig.16 and Fig.18 The atomizer 1000 includes an atomizer seat 1100. A plurality of avoidance grooves 1122 are formed on one side of the atomizer seat 1100 facing the electrode support 210 and are arranged in sequence along the circumferential direction. A first convex portion 1121 for contacting the electrode support 210 is provided between two adjacent avoidance grooves 1122. The second electrode 1150 is correspondingly arranged on one of the first convex portions 1121. The avoidance grooves 1122 and the first convex portion 1121 are used to form a rotation limit fit with the atomizer support 100. The avoidance grooves 1122 and the first convex portion 1121 form a rotation limit fit with the atomizer support 100, so that the atomizer seat 1100 and the atomizer support 100 can rotate synchronously, that is, the atomizer 1000 and the atomizer support 100 can rotate synchronously. By rotating the atomizer support 100, the atomizer 1000 can be driven to rotate, thereby switching the electrical connection and air intake state of the atomizer 1000. In addition, each first protrusion 1121 can pass through the atomizer bracket 100 to abut against the electrode bracket 210, thereby ensuring that the first electrode 220 and the second electrode 1150 can abut against each other to form a stable electrical connection. At the same time, in order to match the structural design of the atomizer bracket 100 that can accommodate multiple atomization units 2000, multiple first protrusions 1121 are provided, and each first protrusion 1121 just corresponds to the position of an atomization unit 2000, so that the atomizer 1000 and the atomizer bracket 100 have a high degree of matching.

[0101] In one embodiment, see Figure 6 and Fig.15 The atomizer bracket 100 includes a plurality of partitions 120, and the partitions 120 are radially distributed with the center line of the atomizer bracket 100 as the center, and a socket 130 is formed between two adjacent partitions 120; the atomizer 1000 includes an atomizer seat 1100, and a plurality of avoidance grooves 1122 arranged in sequence along the circumferential direction are formed on the side of the atomizer seat 1100 facing the electrode bracket 210, and a first convex portion 1121 is provided between two adjacent avoidance grooves 1122, and the first convex portion 1121 passes through the socket 130 to abut against the electrode bracket 210, and the avoidance groove 1122 corresponds to the avoidance partition 120.

[0102] During assembly, each first protrusion 1121 and each partition 120 can be guided to insert each first protrusion 1121 into each socket 130, and each avoidance groove 1122 just avoids the setting of each partition 120, and the first protrusion 1121 and the partition 120 are abutted along the circumferential direction to form a rotation limit between the atomizer bracket 100 and the atomizer 1000. At the same time, the setting of the socket 130, the partition 120, the first protrusion 1121 and the avoidance groove 1122 can play a guiding role in the assembly of the atomizer 1000, ensuring that the atomizer 1000 can be correctly assembled in the atomizer bracket 100.

[0103] In one embodiment, the number of the partitions 120, the number of the sockets 130, the number of the first protrusions 1121, and the number of the avoidance grooves 1122 are all the same as the number of the atomization units 2000. By setting the number of the avoidance grooves 1122 and the first protrusions 1121 to be the same as the number of the atomization units 2000, the atomizer 1000 can be highly matched with the atomizer bracket 100.

[0104] In one embodiment, see Fig.18 , along the axial direction of the atomizer 1000, the height H1 of the first protrusion 1121 ranges from 6mm to 12mm. Specifically, the height H1 of the first protrusion 1121 can be 6mm, 7mm, 8mm, 9mm, 10mm, 11mm or 12mm. Among them, the height H1 of the first protrusion 1121 cannot be too high. If the height of the first protrusion 1121 is too high, it will cause secondary problems, and the high height of the first protrusion 1121 will cause the second electrode 1150 to be too long, which is not conducive to assembly. The high height of the first protrusion 1121 will cause the atomization chamber 1170 to be raised, which is not conducive to the aerosol extraction; in addition, the height of the first protrusion 1121 cannot be too short. If it is too short, the assembly guiding effect of the first protrusion 1121 and the partition 120 on the atomizer 1000 will not be obvious.

[0105] Specifically, the height of the first protrusion 1121 is equal to the height of the second protrusion 2100 , and the axial height of the atomizer 1000 is equal to the axial height of the atomizer unit 2000 , thereby ensuring that the atomizer bracket 100 is compatible with the atomizer 1000 and multiple atomizer units 2000 .

[0106] In one embodiment, the position of the third air inlet 2400 relative to the rotation centerline of the atomizer bracket 100 coincides with the position of the second air inlet 1123 relative to the rotation centerline of the atomizer bracket 100, and the position of the third electrode 2300 relative to the rotation centerline of the atomizer bracket 100 coincides with the position of the second electrode 1150 relative to the rotation centerline of the atomizer bracket 100, thereby ensuring that the atomizer bracket 100 can be compatible with the atomizer 1000 and multiple atomization units 2000 at the same time, that is, the atomizer 1000 has a high degree of matching with the atomizer bracket 100.

[0107] In one embodiment, see Figure 1 , the nozzle 300 is provided with a first indicator mark 350, and the atomizer holder 100 is provided with a second indicator mark (not shown). When the atomizer holder 100 is rotated, when the first indicator mark 350 corresponds to the second indicator mark, the atomizer 1000 just rotates to a state where the first electrode 220 is electrically connected to the second electrode 1150. The setting of the first indicator mark 350 and the second indicator mark can facilitate the user to grasp the rotation angle.

[0108] Specifically, the first indicator mark 350 may be a triangle or an arrow, and the second indicator mark may be an indicator line. It is understandable that in other embodiments of the present application, the first indicator mark 350 may also be set on the electrode bracket 210. In addition, the user may be prompted to rotate to the right position by setting an indicator light. When the first electrode 220 is electrically connected to the second electrode 1150, the indicator light is on. When the first electrode 220 is misaligned with the second electrode 1150, the indicator light is off. This allows the user to intuitively understand whether the atomizer bracket 100 is rotated to the right position.

[0109] In one embodiment, see Fig.14 , Fig.17 and Fig.18 The atomizer 1000 includes an atomizer seat 1100 and a main housing 1200. The atomizer seat 1100 is accommodated in the main housing 1200. The atomizer seat 1100 and the main housing 1200 together enclose a liquid storage chamber 1300. The surface of the atomizer seat 1100 facing the liquid storage chamber 1300 is a liquid inlet surface 1141. The atomizer seat 1100 is concave from the liquid inlet surface 1141 to form a liquid inlet 1115.

[0117] In this embodiment, the liquid inlet surface 1141 is formed on the side of the sealing cover 1140 facing the liquid storage chamber 1300. It can be understood that in other embodiments, when the sealing cover 1140 is not provided on the upper atomizing seat 1110, the liquid guide surface is formed on the upper atomizing seat 1110.

[0118] In one embodiment, a third magnetic member 1160 is installed at the top center of the atomizer 1000 , and the third magnetic member 1160 is used to attract the first magnetic member 230 to ensure the electrical connection stability between the atomizer 1000 and the first electrode 220 .

[0119] In another embodiment of the present application, the suction nozzle 300 forms a rotation limit connection with the atomizer bracket 100, that is, the suction nozzle 300 can rotate with the atomizer bracket 100. A first air outlet 310 is formed on the suction nozzle 300, and the first air outlet 310 is always connected to the second air outlet 1210. When a plurality of atomizing units 2000 are loaded into the atomizer bracket 100, the first air outlet 310 is always kept in communication with each second air outlet 1210. In this way, it can be ensured that the suction nozzle 300 and the atomizer 1000 are always in a connected state, and there is no need to switch the air outlet state of the atomizer 1000.

[0120] In this embodiment, when the rotating shaft 900 is provided on the electrode holder 210, a blind hole may be formed at the center of the atomizer 1000, and the rotating shaft 900 is rotated and inserted into the blind hole to form a rotational connection between the electrode holder 210 and the atomizer holder 100. Alternatively, the rotating shaft 900 may not be provided, and the rotational connection is formed by the electrode holder 210 and the atomizer holder 100 being mutually sleeved, in which case it is not necessary to form a through hole 1220 or a blind hole on the atomizer 1000.

[0122] Optionally, there may be a plurality of insert blocks 113 , and the number of slots 320 is the same as the number of insert blocks 113 . Each insert block 113 is plugged and matched with each slot 320 in a one-to-one correspondence to ensure the stability of the connection between the nozzle 300 and the atomizer bracket 100 .

[0123] At the same time, in order to ensure the sealing of the connection between the suction nozzle 300 and the atomizer bracket 100 , a first sealing ring is also abutted between the suction nozzle 300 and the atomizer bracket 100 .
