For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] The following is for reference. Figures 1-12 The switching device 10 and the atomizer 100 according to embodiments of the present invention are described.

[0055] like Figure 1 and Figure 2 As shown, the switching device 10 can be used in the atomizer 100, which includes a housing 1 and the switching device 10. The switching device 10 is used to place a plurality of atomizing elements 3, and at least a portion of the switching device 10 is disposed inside the housing 1.

[0056] like Figures 1-3 and Figure 6 As shown, the switching device 10 according to an embodiment of the present invention includes a rotating mechanism 2 and a driving mechanism 4.

[0057] Specifically, the housing 1 has an air intake 121. The user can inhale through one end of the air intake 121. The air intake 121 can be located on one end face of the housing 1 in the axial direction and spaced apart from the axis of the housing 1. A rotating mechanism 2 is rotatably disposed within the housing 1. The rotating mechanism 2 has multiple mounting portions 24 spaced apart along its circumferential direction. Multiple atomizing elements 3 are respectively disposed on the multiple mounting portions 24 of the rotating mechanism 2 and arranged along its circumferential direction. The mounting portions 24 can be mounting grooves.

[0058] When the rotating mechanism 2 rotates, it can drive multiple atomizing elements 3 to rotate, thereby aligning different atomizing elements 3 with the inhalation port 121. The multiple atomizing elements 3 can have different flavors, and users can rotate the atomizing element 3 with the desired flavor to be aligned with the inhalation port 121 for use. When different flavored atomizing elements 3 are rotated to be aligned with the inhalation port 121, users can inhale the corresponding flavor, satisfying users' diverse taste needs.

[0059] Additionally, the drive mechanism 4 includes a drive button 41 and a transmission mechanism 42. The drive button 41 can be mounted on the housing 1 and is at least partially exposed outside the housing 1. At least part of the transmission mechanism 42 is located inside the housing 1. The transmission mechanism 42 cooperates with the rotation mechanism 2 and the drive button 41. The drive mechanism 4 is configured to drive the rotation mechanism 42 to rotate when the drive button 41 is pressed, so that one of the atomizing elements 3 is positioned opposite the inhalation port 121. When the user changes the flavor of the atomizing element 3, they can press the drive button 41. Pressing the drive button 41 is converted into rotating the rotation mechanism 2 through the transmission mechanism 42, thereby rotating the atomizing element 3 of the desired flavor to a position opposite the inhalation port 121, which is convenient for the user and does not require any changes to the appearance of existing atomizers.

[0060] In related technologies, multi-flavor atomizers require users to manually change cartridges or rotate an external component to switch the internal atomizing element, which is cumbersome.

[0061] According to the switching device 10 of this utility model embodiment, by setting a rotating mechanism 2, multiple atomizing elements 3 can be set on the rotating mechanism 2 and spaced apart along the circumferential direction of the rotating mechanism. A driving mechanism 4 is also set, which includes a driving button 41 and a transmission mechanism 42. The transmission mechanism 42 cooperates with the rotating mechanism 2 and the driving button 41. The rotating mechanism 2 can be rotated by pressing the driving button 41, thereby switching between multiple atomizing elements 3 and changing different flavors. The operation is convenient.

[0062] In some embodiments of this utility model, the transmission mechanism 42 includes a rotating shaft 421, and a drive button 41 is used to drive the rotating shaft 421 to rotate. The rotating shaft 421 is connected to the rotating mechanism 2 for driving the rotating mechanism 2 to rotate. The structure is simple, occupies little space, and facilitates the arrangement of the atomizer 100.

[0063] Furthermore, such as Figure 2 and Figure 3 As shown, for reference Figure 7 and Figure 8 As shown, the transmission mechanism 42 also includes a gear set 422. The input end of the gear set 422 is connected to the rotating shaft 421, and the output end of the gear set 422 is connected to the rotating shaft 22 of the rotating mechanism 2. Thus, the rotation of the rotating shaft 421 can be transmitted to the rotating mechanism 2 through the gear set 422, driving the rotating mechanism 2 to rotate. The gear set 422 can also adjust the speed ratio between the rotating mechanism 2 and the rotating shaft 421. At the same time, the gear set 422 can adapt the relative position between the rotating shaft 421 and the rotating shaft 22 of the rotating mechanism 2, as well as the angle between the axis of the rotating shaft 421 and the axis of the rotating mechanism 2, to better adapt to the structural arrangement of the rotating mechanism 2 and the drive button 41.

[0064] Furthermore, such as Figure 2 and Figure 3 As shown, the air intake 121 is located on the end face of one axial end of the housing 1 and is spaced apart from the axis of the housing 1, i.e., the air intake 121 is eccentrically positioned. The rotating shaft 22 of the rotating mechanism 2 extends along the axial direction of the housing 1. The drive button 41 passes through the peripheral wall of the housing 1, and the rotating shaft 421 is perpendicular to the rotating shaft 22. The gear set 422 includes a first bevel gear 4221 and a second bevel gear 4222. The axis of the first bevel gear 4221 is perpendicular to the axis of the housing 1 and is connected to the rotating shaft 421. The axis of the second bevel gear 4222 is parallel to or coincides with the axis of the housing 1 and is connected to the rotating shaft 22 and meshes with the first bevel gear 4221. The drive button 41 drives the rotating shaft 421 to rotate, the rotating shaft 421 drives the first bevel gear 4221 to rotate, the first bevel gear 4221 drives the second bevel gear 4222 meshing with it to rotate, the second bevel gear 4222 drives the rotating shaft 22 of the rotating mechanism 2 to rotate, thereby driving the rotating mechanism 2 to rotate, achieving the effect of vertical change of the force transmission direction. The structure is simple and allows for a more reasonable arrangement of the rotating mechanism 2 and the drive button 41.

[0065] Optionally, the transmission ratio of the first bevel gear 4221 and the second bevel gear 4222 is 1, that is, the transmission ratio of the rotating shaft 421 and the rotating mechanism 2 is 1, and the rotation speed of the rotating shaft 421 and the rotation speed of the rotating mechanism 2 are the same, which simplifies the structure.

[0066] In addition, the transmission mechanism 42 also includes a first cap 44 and a second cap 23. The first cap 44 is connected to the rotating shaft 421 and is located on the side of the first bevel gear 4221 away from the drive button 41. It is used to limit the first bevel gear 4221 and prevent the first bevel gear 4221 from dislodging from the rotating shaft 421. The second cap 23 is connected to the rotating shaft 22 of the rotating mechanism 2 and is located on the side of the second bevel gear 4222 away from the drive mechanism 4. It is used to limit the second bevel gear 4222 and prevent the second bevel gear 4222 from dislodging from the rotating shaft 22.

[0067] In some embodiments of this utility model, such as Figure 8 As shown, a guide groove 4211 is provided on the outer peripheral wall of the rotating shaft 421. The drive button 41 is sleeved on the outside of the rotating shaft 421, and a sliding block 411 that cooperates with the guide groove 4211 is provided on the drive button 41. The drive button 41 is configured to drive the rotating shaft 421 to rotate when pressed. When the drive button 41 is pressed, the sliding block 411 on the drive button 41 moves in the pressing direction of the drive button 41, and at the same time, the sliding block 411 on the drive button 41 moves in the guide groove 4211 on the outer peripheral wall of the rotating shaft 421, thereby driving the rotating shaft 421 to rotate. The structure is simple.

[0068] Specifically, such as Figure 8 and Figure 10 As shown, for reference Figure 9 and Figure 11 The two ends of the rotating shaft 421 along its length are a first end 421a and a second end 421b, respectively. The first end 421a is positioned close to the rotation axis of the rotating mechanism 2 relative to the second end 421b. The rotating mechanism 2 has multiple mounting parts 24. The guide groove 4211 includes multiple first limiting grooves 4212 and multiple second limiting grooves 4213. The multiple first limiting grooves 4212 and multiple second limiting grooves 4213 correspond one-to-one with the multiple mounting parts 24. Along the circumferential direction of the rotating shaft 421, the first limiting groove 4212 is inclined toward one end of the first end 421a and the second end 421b, and the second limiting groove 4213 is inclined toward the other end of the first end 421a and the second end 421b. The multiple first limiting grooves 4212 and multiple second limiting grooves 4213 are alternately arranged in the circumferential direction of the rotating shaft 421 and are connected end to end.

[0069] For example, in Figure 6 In the example shown, the atomizing element 3 consists of three atomizing elements spaced apart along the circumferential direction of the rotating mechanism 2, such as... Figures 9-11As shown, there are three first limiting grooves 4212 and three second limiting grooves 4213. The three first limiting grooves 4212 and the three second limiting grooves 4213 are alternately arranged in the circumferential direction of the rotating shaft 421 and connected end to end. That is, along the circumferential direction of the rotating shaft 421, the sequence is: first limiting groove 4212—second limiting groove 4213—first limiting groove 4212—second limiting groove 4213—first limiting groove 4212—second limiting groove 4213—first limiting groove 4212. Furthermore, along the circumferential direction of the rotating shaft 421, the first limiting groove 4212 and the second limiting groove 4213 are inclined toward the first end 421a and the second end 421b of the rotating shaft 421, respectively. That is, along the clockwise or counterclockwise direction of the circumferential direction of the rotating shaft 421, the first limiting groove 4212 is inclined toward one end of the axial direction of the rotating shaft 421, and the second limiting groove 4213 is inclined toward the other end of the axial direction of the rotating shaft 421. The first limiting groove 4212 and the second limiting groove 4213 are formed in a V-shape, and there is an included angle between the first limiting groove 4212 and the second limiting groove 4213. In addition, along the circumferential direction of the rotating shaft 421, the extension angle of two adjacent first limiting grooves 4212 and second limiting grooves 4213 is 120°. When the sliding block 411 moves within the two adjacent first limiting grooves 4212 and second limiting grooves 4213, it can drive the rotating mechanism 2 to rotate 120°.

[0070] Of course, this invention is also applicable to other numbers of atomizing components 3, such as four atomizing components 3, with the rotating mechanism 2 rotating 90° each time; five atomizing components 3, with the rotating mechanism 2 rotating 72° each time; six atomizing components 3, with the rotating mechanism 2 rotating 60° each time, and so on. Various combinations of atomizing components 3 can be achieved simply by adjusting the number and angle of the first limiting groove 4212 and the second limiting groove 4213. Further details will not be elaborated further.

[0071] like Figure 7 and Figure 8As shown, the transmission mechanism 42 also includes an elastic element 423, such as a spring. The elastic element 423 is located between the drive button 41 and the rotating shaft 421, and is used to drive the drive button 41 to move in the direction away from the first end 421a, that is, in the direction towards the outside of the housing 1. For example, in the rotation direction along the shaft 421, the first limiting groove 4212 is inclined towards the axial end of the shaft 421 near the outside of the housing 1. When the drive button 41 is pressed, the elastic element 423 is compressed, and the sliding block 411 on the drive button 41 can move along the first limiting groove 4212 until the end of the first limiting groove 4212 near the inside of the housing 1 and the connection point of the second limiting groove 4213. Since the drive button 41 moves along the axis of the shaft 421, the shaft 421 is driven to rotate. When the sliding block 411 moves to the connection point of the first limiting groove 4212 and the second limiting groove 4213 near the inside of the housing 1, the drive button 41 is released. Under the action of the elastic element 423, the drive button 41 moves along the axis of the shaft 421 towards the outside of the housing 1, and the sliding block 411 enters the second limiting groove 4213, causing the shaft 421 to continue to rotate.

[0072] When the drive button 41 is pressed once, the sliding block 411 on the drive button 41 can move within a first limiting groove 4212 and a second limiting groove 4213. The number of atomizing elements 3 is the same as the number of first limiting grooves 4212 and second limiting grooves 4213. When the atomizing elements 3 are evenly distributed along the circumferential direction of the rotating mechanism 2, the included angle between two adjacent atomizing elements 3 is the same as the included angle between the ends of a first limiting groove 4212 and a second limiting groove 4213 that are away from each other. That is, pressing the drive button 41 once can adjust one atomizing element 3 to a position opposite to the inhalation port 121.

[0073] Of course, this utility model is not limited to this. The number of the first limiting groove 4212 and the number of the second limiting groove 4213 can both be an integer multiple N of the number of atomizing elements 3, where N is an integer greater than or equal to 1. Pressing the drive button 41 N times will adjust one atomizing element 3 to the position opposite to the air inlet 121. For example, when N is 2, the drive button 41 needs to be pressed twice each time the atomizing element 3 is adjusted.

[0074] Furthermore, such as Figure 9 and Figure 10As shown, the connection point between the first limiting groove 4212 and the second limiting groove 4213 and the first end 421a (the end closest to the outside of the housing 1) is the first connection point 421c. The first connection point 421c is provided with a sliding groove 4214, which is located on the side of the first connection point 421c opposite to the first end 421a. When the sliding block 411 is located in the sliding groove 4214, one of the atomizing elements 3 is opposite to the air intake 121. The sliding groove 4214 can fix the sliding block 411. After pressing the drive button 41 once, the sliding block 411 can be fixed in the sliding groove 4214, ensuring the reliability of the sliding block 411, thereby ensuring the reliability of the rotating shaft 421, and further ensuring the reliability of the rotating mechanism 2, and the reliability of the atomizing element 3 located on the rotating mechanism 2. In addition, when the sliding block 411 is located in the groove 4214, one atomizing element 3 is exactly opposite to the air intake 121, thereby ensuring the reliability of the atomizing element 3 opposite to the air intake 121 and ensuring the user experience.

[0075] In some embodiments of this utility model, such as Figure 9 As shown, along the rotation direction of the shaft 421, the first limiting groove 4212 is inclined toward the second end 421b (the end closer to the outside of the housing 1), and correspondingly, the second limiting groove 4213 is inclined toward the first end 421a (the end closer to the inside of the housing 1). The first connection 421c has a first limiting point 4215, which is the connection point of the first limiting groove 4212 and the second limiting groove 4213. The first limiting point 4215 is located on the side of the first connection 421c closer to the first end. Along the rotation direction of the shaft 421, at the same first connection 421c, the first limiting point 4215 is flush with the front sidewall of the slide 4214 or located in front of the front sidewall of the slide 4214. This ensures that when the drive button 41 is pressed, the sliding block 411 on the drive button 41 moves towards the end of the rotating shaft 421 that is closer to the inside of the housing 1 and can smoothly enter the first limiting groove 4212, thereby ensuring the accuracy of the rotation direction of the rotating shaft 421, thus ensuring the reliability of the drive of the rotating mechanism 2 and the reliability of the switching of the atomizing element 3.

[0076] In some embodiments of this utility model, such as Figure 11 and Figure 12As shown, along the rotation direction of the shaft 421, the first limiting groove 4212 is inclined toward the second end 421b, and correspondingly, the second limiting groove 4213 is inclined toward the first end 421a. The connection point of the first limiting groove 4212 and the second limiting groove 4213 near the first end 421a is the second connection point 421d. The second connection point 421d has a second limiting point 4216 and a third limiting point 4217. The second limiting point 4216 and the third limiting point 4217 are the two connection points of the first limiting groove 4212 and the second limiting groove 4213. The second limiting point 4216 is located on the side of the third limiting point 4217 near the first end 421a. Along the rotation direction of the shaft 421, the second limiting point 4216 is located behind the third limiting point 4217. This ensures that when the sliding block 411 moves to the connection point of the first limiting groove 4212 and the second limiting groove 4213 near the first end 421a, i.e. the end inside the housing 1, it can smoothly enter the second limiting groove 4213 under the action of the elastic element 423, thereby ensuring the accuracy of the rotation direction of the rotating shaft 421, thus ensuring the reliability of the drive of the rotating mechanism 2 and the reliability of the switching of the atomizing element 3.

[0077] Furthermore, such as Figure 11 and Figure 12 As shown, along the circumferential direction of the rotating shaft 421, the distance between the second limiting point 4216 and the third limiting point 4217 is 'a', and the size of the area where the sliding block 411 is furthest from the first end 421a is 'b', satisfying that a > b. This avoids the problem that the sliding block 411, when moving towards the outside of the housing 1 under the action of the elastic member 423, will abut against the third limiting point 4217 and fail to smoothly enter the second limiting groove 4213. It ensures that the sliding block 411 can smoothly enter the second limiting groove 4213, thereby ensuring the accuracy of the rotation direction of the rotating shaft 421, thus ensuring the reliability of the drive for the rotating mechanism 2 and the reliability of the switching of the atomizing element 3.

[0078] For example, in Figure 12 In the example shown, the side surface of the sliding block 411 facing away from the inside of the housing 1 includes a first surface perpendicular to the axis of the rotating shaft 421 and a second surface at an acute or obtuse angle to the axis of the rotating shaft 421. Along the rotation direction of the rotating shaft 421, the second surface is inclined toward the inside of the housing 1. The first surface is at the maximum distance from the end of the rotating shaft 421 closest to the inside of the housing 1 and its length along the circumferential direction of the rotating shaft 421 is b. Along the circumferential direction of the rotating shaft 421, the distance between the second limiting point 4216 and the third limiting point 4217 is a, and satisfies: a > b.

[0079] In this application, the rotation mechanism 2 rotates to a specific angle by means of the design and coordination of the dimensions and angles of the sliding block 411 and the first limiting groove 4212 and the second limiting groove 4213 on the rotating shaft 421, which can realize the rotation of more than two atomizing elements 3. When the user needs to change to a different flavor of atomizing element 3, he / she only needs to press the external drive button 41, press it once and release it, and the internal rotating mechanism 2 will rotate by the corresponding angle to switch to another flavor of atomizing element 3.

[0080] In some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, for reference Figure 3 The drive mechanism 4 also includes a sleeve 43, which is fixed inside the housing 1. At least a portion of the rotating shaft 421 passes through the sleeve 43, and a portion of the drive button 41 passes through the sleeve 43. This allows for the fixing of the drive button 41 and the rotating shaft 421, guides the movement of the drive button 41, and limits the rotation of the rotating shaft 421.

[0081] Furthermore, such as Figure 3 As shown, the sleeve 43 has a stepped surface 431 inside, and the outer peripheral wall of the rotating shaft 421 has a limiting protrusion 4218. The side of the limiting protrusion 4218 facing away from the drive button 41 abuts against the stepped surface 431. This can limit the rotation of the rotating shaft 421, preventing the rotating shaft 421 from moving towards the inside of the housing 1 when the drive button 41 is pressed, thus preventing the drive button 41 from driving the rotating shaft 421 to rotate. This ensures the reliability of the drive button 41 driving the rotating shaft 421 to rotate, thereby ensuring the reliability of driving the rotating mechanism 2 and the reliability of switching the atomizing element 3.

[0082] In some embodiments of this utility model, such as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the atomizer 100 also includes a rotating bracket 5, which is fixed inside the housing 1. At least a portion of the transmission mechanism 42 is disposed on the rotating bracket 5, and the rotating mechanism 2 is located on the side of the rotating bracket 5 facing the air inlet 121. The rotating bracket 5 can support and fix the rotating mechanism 2 and the transmission mechanism 42, thereby ensuring the reliability of the operation of the rotating mechanism 2 and the transmission mechanism 42.

[0083] Furthermore, such as Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the atomizer 100 also includes a rotary sealing ring 51, which is disposed between the rotary support 5 and the rotary mechanism 2. The rotary sealing ring 51 and the rotary support 5 together define an air intake channel 52, which communicates with the atomization channel of one of the atomizing elements 3. Specifically, the air intake channel 52 is opposite to the air inlet 121 in the axial direction of the housing 1. The atomization channel of the atomizing element 3 opposite to the air inlet 121 communicates with the air intake channel 52 and the air inlet 121. The housing 1 is provided with an air inlet 111 that communicates with the air intake channel 52. When the rotary mechanism 2 rotates internally, the sealing performance of the rotary sealing ring 51 is not affected. The rotary sealing ring 51 is used to seal the air intake channel 52, the atomization channel of the atomizing element 3 that communicates with the air intake channel 52, and the atomization channel of the atomizing element 3 that does not communicate with the air intake channel 52, thereby improving the reliability of the atomizer 100.

[0084] In this invention, the rotating bracket 5 and the rotating sealing ring 51 do not rotate; only the rotating mechanism 2 rotates. Only one air intake channel 52 and one air inlet 111 are provided. The rotating mechanism 2 drives multiple atomizing elements 3 to rotate, thereby connecting the air intake channel 52 with the atomization channels of different atomizing elements 3.

[0085] In some embodiments of this utility model, the rotating mechanism 2 is adapted to be provided with a plurality of atomizing elements 3 arranged along the circumferential direction of the rotating mechanism 2. A first magnet (not shown) is provided on the side of the atomizing element 3 facing the rotating support 5, and a second magnet 53 cooperating with the plurality of first magnets is provided on the side of the rotating support 5 facing the atomizing element 3. When the first magnet and the corresponding second magnet 53 are opposite to each other and magnetically connected, one of the atomizing elements 3 is positioned opposite to the air intake 121. Thus, by attracting the first magnet and the second magnet 53, the position of the atomizing element 3 can be made more accurate, and after the atomizing element 3 is switched, the purpose of fixing the atomizing element 3 can be achieved.

[0086] Optionally, each atomizing element 3 is provided with two first magnets below it. The two first magnets are spaced apart along the circumferential direction of the rotating bracket 5. The rotating bracket 5 has two second magnets 53 that cooperate with each atomizing element 3. For example, when there are three atomizing elements 3, there are six second magnets 53. The multiple second magnets 53 are spaced apart along the circumferential direction of the rotating bracket 5.

[0087] The atomizer 100 according to an embodiment of the present invention is described in detail below.

[0088] Specifically, such as Figures 1-3 As shown, the atomizer 100 includes a housing 1 and the aforementioned switching device 10.

[0089] The housing 1 has an air intake 121, at least a portion of the switching device 10 is disposed inside the housing 1, the rotating mechanism 2 is rotatably disposed inside the housing 1, at least a portion of the transmission mechanism 42 is disposed inside the housing 1, and the drive button 41 is disposed on the housing 1 and at least a portion is exposed outside the housing 1.

[0090] According to the atomizer 100 of this utility model, by setting the switching device 10 mentioned above, a rotating mechanism 2 is set, and multiple atomizing elements 3 can be set on the rotating mechanism 2 and spaced apart along the circumferential direction of the rotating mechanism 2. A driving mechanism 4 is set, which includes a driving button 41 and a transmission mechanism 42. The transmission mechanism 42 cooperates with the rotating mechanism 2 and the driving button 41. The rotating mechanism 2 can be rotated by pressing the driving button 41, thereby switching between multiple atomizing elements 3, changing different flavors, and is easy to operate.

[0091] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the rotating mechanism 2 is provided with multiple mounting portions 24 spaced apart along the circumferential direction of the rotating mechanism 2. The atomizer 100 also includes multiple atomizing elements 3, which are respectively disposed in the multiple mounting portions 24. One of the atomizing elements 3 is arranged opposite to the inhalation port 121. The multiple atomizing elements 3 can be different flavors. Users can inhale the corresponding flavor by rotating the atomizing element 3 of the corresponding flavor to be opposite to the inhalation port 121, thus meeting the user's needs.

[0092] In some embodiments of this utility model, such as Figure 6 As shown, the housing 1 includes an outer shell 11, an atomizing nozzle 12, and a bottom cover 13. The outer shell 11 is open at both axial ends. A drive button 41 is located on the outer shell 11. The atomizing nozzle 12 is connected to one axial end of the outer shell 11, and an air intake 121 is located on the atomizing nozzle 12. The bottom cover 13 is connected to the end of the outer shell 11 opposite to the atomizing nozzle 12. This facilitates the installation and assembly of components inside the housing 1 and improves assembly efficiency.

[0093] Furthermore, such as Figure 2 , Figure 4 and Figure 6 As shown, the atomizer 100 also includes an atomizing element sealing ring 122, which is disposed between the atomizing nozzle 12 and the outer shell 11, thereby ensuring the reliability of the seal between the outer shell 11 and the atomizing nozzle 12. Alternatively, the atomizer 100 may also include a bottom cover sealing ring 131, which is disposed between the bottom cover 13 and the outer shell 11, ensuring the reliability of the seal between the bottom cover 13 and the outer shell 11.

[0094] In some embodiments of this utility model, such as Figure 2 , Figure 6 and Figure 7As shown, the atomizing nozzle 12 has a third magnet 123, and the rotating mechanism 2 has a fourth magnet 21 on the side facing the atomizing nozzle 12. The third magnet 123 and the fourth magnet 21 are magnetically connected. This allows the rotating mechanism 2 and the atomizing nozzle 12 to be fixed together, preventing the rotating mechanism 2 from detaching downwards from the atomizing nozzle 12.

[0095] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the atomizer 100 also includes a main board assembly 6, which is disposed within the housing 1. The main board assembly 6 has a first connection terminal 61, which is opposite to the inhalation port 121 in the axial direction of the housing 1. The atomizing element 3 has a second connection terminal 32, which is connected to the first connection terminal 61. Therefore, only one set of first connection terminals 61 is needed to connect to the second connection terminals 32 on different atomizing elements 3, saving costs.

[0096] The first connecting terminal 61 is mounted on the rotating bracket 5 and the rotating sealing ring 51. Since the rotating bracket 5 and the rotating sealing ring 51 do not rotate, it is more convenient to install a set of first connecting terminals 61.

[0097] In addition, such as Figure 2 and Figure 3 As shown, the mainboard assembly 6 is equipped with a pressure sensor, and the housing 1 also has a pressure channel 54 communicating with the air intake channel 52. The pressure sensor is located inside the pressure channel 54 or at one end. When the user starts inhaling, air enters the air intake channel 52 from the air intake port 111, and then reaches the air intake port 121 through the atomization channel of the atomizing element 3. At the same time, the pressure channel 54 generates negative pressure, which drives the pressure sensor on the mainboard assembly 6 to start working. The first connection terminal 61 on the mainboard assembly 6 is connected to the second connection terminal 32 on the atomizing element 3 opposite to the air intake port 121, thus realizing the atomization of the atomized oil.

[0098] The pressure channel 54 can be defined by the rotating bracket 5.

[0099] In some embodiments of this utility model, such as Figure 2 and Figure 6 As shown, the atomizer 100 also includes a battery 7, which is located inside the housing 1 and is used to power the mainboard assembly 6.

[0100] In some embodiments of this utility model, the atomizer 100 further includes an atomizing nozzle sealing ring 124. The atomizing nozzle sealing ring 124 is disposed inside the housing 1 and located between the atomizing element 3 and the air intake 121. The atomizing nozzle sealing ring 124 has multiple connecting holes, which are respectively arranged opposite to multiple atomizing elements 3. When the rotating mechanism 2 rotates internally, the sealing performance of the atomizing nozzle sealing ring 124 is not affected. Therefore, when one of the atomizing elements 3 is opposite to the air intake 121, the atomization channel of the air intake 121 and the atomizing element 3 can be sealed, ensuring the reliability of the atomizer 100's operation.

[0101] Based on the above, the assembly steps of the atomizer 100 according to an embodiment of the present utility model are described.

[0102] First, assemble the internal rotating mechanism assembly of atomizer 100:

[0103] Specifically, first, the fourth magnet 21 is installed into the groove at the upper end of the rotating mechanism 2. Then, the second bevel gear 4222 is installed onto the lower rotating shaft 22 of the rotating mechanism 2, and fixedly connected by the limiting pin on the rotating shaft 22 and the groove of the second bevel gear 4222. Next, the rotating shaft 421 is installed into the sleeve 43, and the first bevel gear 4221 is fitted onto it. The first cap 44 is then placed on top to fix the first bevel gear 4221 and the rotating shaft 421, and fixed by the limiting pin on the rotating shaft 421 and the groove on the first bevel gear 4221. The first bevel gear 4221 is installed into the slot of the bracket of the rotating mechanism 2, the rotating sealing ring 51 is placed on top, and the rotating mechanism 2 is fitted onto it. Finally, the second cap 23 is placed on the rotating shaft 22 at the bottom of the bracket of the rotating mechanism 2 to fix it, thus forming the rotating mechanism 2 assembly. The first bevel gear 4221 and the second bevel gear 4222 are designed to be vertically meshed with two conical gears to achieve simultaneous rotation of the two gears, thereby realizing the effect of vertical direction conversion of the rotating mechanism 2.

[0104] Then proceed with the final assembly:

[0105] Specifically, the atomizing nozzle sealing ring 124 and the third magnet 123 are installed into the atomizing nozzle 12. The atomizing nozzle 12 is then inserted into the outer shell 11 from the top, and is tightly fixed to the outer shell 11 through a slot and the atomizing component sealing ring 122. The atomizing component 3 is then installed into the rotating mechanism 2. The assembled rotating mechanism 2 assembly is then inserted into the outer shell 11 from the bottom. The fourth magnet 21 on the rotating mechanism 2 and the third magnet 123 on the atomizing nozzle 12 are mutually attracted and engaged, and installed in the designated position. The elastic element 423, such as a spring, is then installed. Inside the drive button 41, the rotating shaft 421 is inserted through the side wall hole of the outer casing 11. The sliding block 411 on the drive button 41 is fixed in place with the first limiting groove 4212 and the second limiting groove 4213 on the rotating shaft 421, thereby achieving the purpose of pressing the drive button 41 to drive the internal rotating mechanism 2 to rotate. Finally, the battery 7 and the main board assembly 6 are installed on the bottom cover 13 and the whole assembly is installed into the outer casing 11. The bottom cover 13 and the outer casing 11 are fixed in place by the slot and the bottom cover sealing ring 131, and the whole machine is assembled.
