[0031] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0032] This application provides an atomization device. Figure 1-Figure 4 , the atomizing device 100 may include a housing assembly 10, an atomizing assembly 20, and a control assembly 30. The housing assembly 10 has a receiving chamber 14, and the atomizing assembly 20 is installed in the receiving chamber 14. The atomizing assembly 20 is provided with an oil storage chamber 24, and the oil storage chamber 24 stores an atomizing matrix, and the atomizing assembly 20 is used to atomize the atomizing matrix into an aerosol. The control assembly 30 is used to control the working state of the atomizing assembly 20. For example, the control assembly 30 can control the atomizing assembly 20 to heat the atomizing matrix to generate an aerosol or stop heating according to the user's suction action.

[0033] like Figure 1 , Figure 2 As shown, the housing assembly 10 includes a first housing 11, a second housing 12 and a nozzle housing 13. The first housing 11 has an inner space, and the second housing 12 and the nozzle housing 13 are enclosed with the first housing 11 to form a receiving cavity 14, so that the number of parts of the housing assembly 10 is small, the assembly process of the housing assembly 10 can be simplified, and the assembly efficiency can be improved. The atomizing device 100 has a length direction. For example, the length direction can be Figure 3The first shell 11 is provided with a first mounting hole 1121 on one side perpendicular to the length direction, and the second shell 12 is installed in the first mounting hole 1121. The first shell 11 is provided with a second mounting hole 1112 at one end in the length direction, and the nozzle shell 13 is installed in the second mounting hole 1112. Optionally, the connection between the second shell 12, the nozzle shell 13 and the first shell 11 can be bonding, clamping or threaded connection. The nozzle shell 13 can be used for the user to inhale, and the nozzle shell 13 is connected to the atomizer assembly 20 so that the aerosol generated by the atomization of the atomizer assembly 20 can reach one end for the user to inhale.

[0034] Generally speaking, in order to ensure the overall appearance of the shell assembly 10, the area of ​​the bottom of the shell assembly 10 is usually smaller than the area of ​​the side of the shell assembly 10. For example, the area of ​​the bottom of the first shell 11 is set to be smaller than the area of ​​the side of the first shell 11. The first mounting hole 1121 is opened on the side of the first shell 11 perpendicular to the length direction, and the components in the accommodating cavity 14 can be installed through the first mounting hole 1121. Compared with the first mounting hole 1121 opened in other parts, such as the end (specifically, the bottom) of the first shell 11 in the length direction, the first mounting hole 1121 can have a relatively large opening area, thereby providing a relatively large operating space, which is conducive to assembly operations and can further improve assembly efficiency.

[0035] See also Figure 2 , Figure 3, the atomization assembly 20 may include an atomization core 21 and an oil cup 22, and the atomization core 21 is installed in the oil cup 22. The oil cup 22 has an oil storage chamber 24, and the atomization core 21 is installed in the oil storage chamber 24. The oil storage chamber 24 is used to store the atomization matrix. The atomization matrix can be stored in the oil storage chamber 24 in the form of a liquid, or it can be stored with the help of a storage medium. For example, the atomization assembly 20 also includes an oil storage member 23, the oil storage member 23 is filled in the oil storage chamber 24, the oil storage member 23 is wrapped outside the atomization core 21, the oil storage member 23 is a porous medium, such as fiber cotton, and the oil storage member 23 can adsorb the atomization matrix, thereby storing the atomization matrix in the oil storage chamber 24. Optionally, the oil cup 22 includes an oil cup shell 221 and an oil cup base 222, and the oil cup shell 221 and the oil cup base 222 are surrounded to form an oil storage chamber 24. The atomization core 21 may include a heating element 211, a liquid guide 212 and an atomization tube 213. The function of the liquid guide 212 is to transfer the atomized matrix to the heating element 211, and the function of the heating element 211 is to generate heat by electricity, thereby heating the atomized matrix to atomize it. Exemplarily, the liquid guide 212 is a cotton liquid guide, and the liquid guide 212 is wrapped around the outer periphery of the heating element 211. The liquid guide 212 is at least partially accommodated in the atomizing tube 213, so that the heating element 211, the liquid guide 212 and the atomizing tube 213 form a relatively independent module, and then assembled into the oil storage chamber 24 through the atomizing tube 213, such as the atomizing tube 213 is installed on the oil cup base 222, so as to realize the modular assembly of the atomizing core 21, which can improve production efficiency.

[0036] like Figure 2-Figure 4 As shown, the control assembly 30 may include a battery 31, a control circuit board 32, an airflow sensor 33, a bracket 34 and a base 35 installed in the accommodating chamber 14. The battery 31 is used to provide electrical energy when the atomizing device 100 is working. The bracket 34 is installed at one end of the oil cup 22, for example, the bracket 34 is inserted in the oil cup base 222. The airflow sensor 33 is installed on the control circuit board 32, the control circuit board 32 is attached to the side of the bracket 34 away from the oil cup 22, the bracket 34 is covered on the airflow sensor 33, the base 35 is installed on the side of the control circuit board 32 away from the airflow sensor 33, and the base 35 is connected to the bracket 34, so that the control circuit board 32, the airflow sensor 33, the bracket 34 and the base 35 form a relatively independent module, realize the modular assembly of components, and improve production efficiency. The airflow sensor 33 is configured to control the electrical connection conduction state between the atomizing assembly 20 and the battery 31 according to the user's suction action. Specifically, when the user inhales through the nozzle shell 13, the airflow sensor 33 senses the change in airflow, and the airflow sensor 33 controls the atomization component 20 to be connected to the battery 31, and the atomization component 20 can heat the atomization matrix to generate aerosol; when the user stops inhaling, the airflow sensor 33 does not sense the change in airflow within a preset time period, and the airflow sensor 33 controls the atomization component 20 to be disconnected from the battery 31, and the atomization component 20 stops heating.

[0037] Please continue reading Figure 2-Figure 4 The control assembly 30 further includes a control key 37. The control key 37 is mounted on the housing assembly 10, such as the second housing 12, so that the user can control the atomization device 100 through the control key 37. Exemplarily, the user can turn on or off the atomization device 100 through the control key 37, or set the heating mode of the atomization device 100 through the control key 37, such as setting the atomization device 100 to heat at normal power or high power.

[0038] See also Figure 2-Figure 4 , the atomizing device 100 may further include a display assembly 40, a second sealing member 50, a liquid absorbing member 60 and a shielding member 70. The display assembly 40 is installed in the accommodating chamber 14, and the display assembly 40 is used to display information of the atomizing device 100. Exemplarily, the information displayed by the display assembly 40 may be one or more of the power information, heating mode, heating power, atomizing matrix inventory and brand logo of the atomizing device 100. The display assembly 40 may include a display screen 41 and a display circuit board 42, the display screen 41 is electrically connected to the display circuit board 42, and the display circuit board 42 is used to control the information display of the display screen 41. The display screen 41 may be installed on the display circuit board 42. A display area 1211 is provided on the second housing 12, and the display assembly 40 is arranged adjacent to the second housing 12, and the information displayed by the display assembly 40 is visible through the display area 1211.

[0039] The second sealing member 50, the liquid absorbing member 60 and the shielding member 70 are installed between the atomizing assembly 20 and the nozzle housing 13. The second sealing member 50 is used to seal the oil cup 22 to prevent leakage of the atomized matrix in the oil cup 22. The liquid absorbing member 60 is used to absorb condensed liquid in the aerosol to improve the taste of the aerosol. The shielding member 70 is configured to be opaque. When the nozzle housing 13 is made of a transparent material, the shielding member 70 can prevent the user from observing the liquid absorbing member 60 through the nozzle housing 13 to prevent the liquid absorbing member 60 from changing color after absorbing condensed liquid or atomized matrix and affecting the appearance of the product.

[0040] See also Figure 5-Figure 6, the heating element 211 includes a heating portion 2111 and a pin 2112. The heating portion 2111 is used to heat the atomized matrix to generate an aerosol, and the pin 2112 is used for the electrical connection between the heating portion 2111 and an external power source. The external power source refers to a power source arranged outside the heating element 211. For example, the heating portion 2111 can be electrically connected to the battery 31 installed in the accommodating chamber 14 through the pin 2112, thereby providing the heating portion 2111 with electrical energy for operation. The number of heating portions 2111 is at least three. For example, the number of heating portions 2111 is 3, 4 or more. At least three heating portions 2111 are arranged in parallel. At least three heating portions 2111 are arranged to heat the atomized matrix independently or in combination, so that the heating power of the heating portion 211 can be controlled by the heating portion 2111 working independently or in combination. The heating portion 211 has a variety of heating modes to meet the different usage requirements of users. The pin 2112 includes at least one common pin and at least three independent pins. The common pin is used to establish an electrical connection with an electrode having a first polarity, and the independent pin is used to establish an electrical connection with an electrode having a second polarity. The common pin is electrically connected to at least two heating parts 2111, so that some heating parts 2111 share one pin, which can reduce the number of pins and facilitate the electrical connection between the heating element 211 and the external power supply.

[0041] The more the number of heating parts 2111, the more heating power formed by the independent or combined operation of the heating parts 2111, and accordingly, the more heating modes that the heating element 211 can select, but it will increase the difficulty of preparing the heating element 211, and increase the number of pins 2112, which is not conducive to the electrical connection between the heating element 211 and the external power supply. Optionally, the number of heating parts 2111 is 3, and the heating part 2111 includes a first heating part 2111A, a second heating part 2111B, and a third heating part 2111C, which can not only make the heating element 211 have more heating modes, but also reduce the difficulty of preparing the heating element 211, and the number of pins 2112 will not be too many, which is convenient for the electrical connection between the heating element 211 and the external power supply. The independent pins include a first independent pin 2112A, a second independent pin 2112B, and a third independent pin 2112C that are electrically connected to the first heating part 2111A, the second heating part 2111B, and the third heating part 2111C, respectively. There is one common pin, and one common pin 2112D is electrically connected to the first heating part 2111A, the second heating part 2111B and the third heating part 2111C. The first heating part 2111A, the second heating part 2111B and the third heating part 2111C share one common pin 2112D. Under the condition that the three heating parts 2111 can heat the atomized matrix independently or in combination, the number of pins 2112 is minimized. At this time, the number of pins 2112 is four, which facilitates the electrical connection between the heating element 211 and the external power supply.

[0042] When the number of pins 2112 is large, for example, the heating element 211 is provided with at least four pins 2112, and the pins 2112 pass through related components to connect with the power supply, the size of the related components will be larger, which is not conducive to the miniaturization of the product.

[0043] See also Figure 7-10 , the oil cup 22 is provided with a first air inlet hole 2222, and the bracket 34 is provided with a first wiring hole 3411, a second wiring hole 3412 and a second air inlet hole 3413. At least one of the pins 2112 is passed through the first wiring hole 3411, and the remaining pins 2112 are passed through the second wiring hole 3412, so that multiple pins 2112 pass through the two wiring holes, and the passing positions of the pins 2112 are dispersedly arranged on the bracket 34, which can improve the space utilization of the bracket 34 and reduce the size of the bracket 34. The first wiring hole 3411, the second wiring hole 3412 and the second air inlet hole 3413 can be arranged adjacent to each other to reduce the size of the bracket 34. The second air inlet hole 3413 is connected to the first air inlet hole 2222, and external air can enter the atomization assembly 20 through the second air inlet hole 3413 and the first air inlet hole 2222. The atomization device 100 has a length direction. Exemplarily, the length direction can be Figure 3 The Z-axis direction in the longitudinal direction. The projection of the first air inlet hole 2222 on the bracket 34 along the longitudinal direction at least partially falls outside the second air inlet hole 3413. That is, the projection of the first air inlet hole 2222 on the bracket 34 along the longitudinal direction does not overlap with the second air inlet hole 3413, or there is a partial overlap, but not a complete overlap. The projection of the first air inlet hole 2222 on the bracket 34 along the longitudinal direction is set to at least partially fall outside the second air inlet hole 3413, so that the second air inlet hole 3413 and the first air inlet hole 2222 are staggered in a plane perpendicular to the longitudinal direction, and the adjacent area of ​​the projection of the first air inlet hole 2222 on the bracket 34 can be used to arrange the first wiring hole 3411 and the second wiring hole 3412. The arrangement of the first wiring hole 3411 and the second wiring hole 3412 is more compact, which further improves the space utilization of the bracket 34, reduces the size of the bracket 34, and is conducive to the miniaturization of the product.

[0044] Optionally, a connecting pipe is provided between the second air inlet 3413 and the first air inlet 2222. However, since the second air inlet 3413 and the first air inlet 2222 are staggered in a plane perpendicular to the length direction, the connecting pipe needs to be bent or tilted in the length direction, which may cause resistance to the airflow, and the airflow is not smooth enough.

[0045] like Figure 8 , Figure 11-13As shown, the bracket 34 includes a bracket bottom wall 341 and a first bracket side wall 342, and the first bracket side wall 342 is connected to a side of the bracket bottom wall 341 close to the oil cup 22. The first wiring hole 3411, the second wiring hole 3412 and the second air inlet hole 3413 are opened in the bracket bottom wall 341. The first bracket side wall 342 is arranged around the first wiring hole 3411, the second wiring hole 3412 and the second air inlet hole 3413. The first bracket side wall 342 can be arranged adjacent to the first wiring hole 3411, the second wiring hole 3412 and the second air inlet hole 3413, and the enclosed area of ​​the first bracket side wall 342 is slightly larger than the distribution range of the first wiring hole 3411, the second wiring hole 3412 and the second air inlet hole 3413, so as to improve the space utilization of the bracket 34. The first bracket side wall 342 and the bracket bottom wall 341 are enclosed to form an air inlet cavity 3421. The first bracket side wall 342 abuts against the oil cup 22, and the second air inlet hole 3413 is connected to the first air inlet hole 2222 via the air inlet cavity 3421. The second air inlet hole 3413 is arranged to be connected to the first air inlet hole 2222 through the air inlet cavity 3421 enclosed by the first bracket side wall 342 and the bracket bottom wall 341. The air inlet cavity 3421 forms a buffer space for airflow, expands the flow channel of the airflow, can reduce the resistance of the airflow, and makes the airflow flow smoother.

[0046] See also Figure 8 , Figure 11-13 The bracket 34 includes a second bracket side wall 343, which is connected to a side of the bracket bottom wall 341 close to the oil cup 22 along the outer periphery of the bracket bottom wall 341, and the second bracket side wall 343 is arranged outside the first bracket side wall 342. The second bracket side wall 343, the first bracket side wall 342 and the bracket bottom wall 341 are enclosed to form a collection chamber 3431. The collection chamber 3431 can be used to collect condensate in the atomization assembly 20, or atomization matrix seeping from the atomization core 21, which can reduce the risk of leakage of the atomization device 100.

[0047] Alternatively, if Figure 2-Figure 4 As shown, the collection chamber 3431 is provided with an oil absorbing member 38, which is used to absorb the condensate or atomized matrix in the collection chamber 3431, reduce the fluidity of the condensate or atomized matrix, and further reduce the risk of leakage of the atomizing device 100. The oil absorbing member 38 is a porous medium, such as fiber cotton.

[0048] See also Figure 4 , Figure 11-13, a sensor installation cavity 3414 is provided on the side of the bracket bottom wall 341 away from the oil cup 22, and the airflow sensor 33 is accommodated in the sensor installation cavity 3414. The sensor installation cavity 3414 is arranged adjacent to the second bracket side wall 343, so that the installation position of the airflow sensor 33 is close to the peripheral edge area of ​​the bracket bottom wall 341, which can reduce the influence of the airflow sensor 33 on the collection cavity 3431, thereby improving the utilization rate of the collection cavity 3431. In addition, since the second bracket side wall 343 is arranged outside the first bracket side wall 342, the sensor installation cavity 3414 is arranged adjacent to the second bracket side wall 343, so that the installation position of the airflow sensor 33 is located outside the first bracket side wall 342, and the first bracket side wall 342 separates the airflow sensor 33 from the first air inlet 2222, which can reduce the condensate flowing from the first air inlet 2222 to the airflow sensor 33, thereby improving the reliability of the airflow sensor 33. The second bracket side wall 343 is configured to be at least part of the cavity wall of the sensor installation cavity 3414, so that part of the cavity wall of the sensor installation cavity 3414 is shared with the second bracket side wall 343, which can not only save space of the bracket 34 and improve the space utilization of the bracket 34, but also reduce material usage and reduce costs.

[0049] like Figure 7 , Figure 11-13 As shown, a plurality of electrode blind holes 3415 are provided on the side of the bottom wall 341 of the bracket away from the oil cup 22. The number of the electrode blind holes 3415 corresponds to the number of the pins 2112. The pins 2112 extend to the side of the bracket 34 away from the oil cup 22 through the first wiring hole 3411 and the second wiring hole 3412, and are at least partially accommodated in the electrode blind holes 3415. Exemplarily, the pins 2112 can be attached to the hole wall of the electrode blind holes 3415. The control circuit board 32 is provided with electrodes 321, which are inserted into the electrode blind holes 3415 and are electrically connected to the pins 2112. The pins 2112 are arranged to be accommodated in the electrode blind holes 3415. When the control circuit board 32 is assembled to one side of the bracket 34, the electrodes 321 are inserted into the electrode blind holes 3415 to realize the electrical connection between the pins 2112 and the control circuit board 32, without the need for an additional pin connection process, which can simplify the assembly process of the atomization device 100 and improve the assembly efficiency. A plurality of electrode blind holes 3415 are distributed along the periphery of the first bracket side wall 342, and the first bracket side wall 342 is configured to be at least part of the hole wall of the electrode blind hole 3415, so that part of the hole wall of the electrode blind hole 3415 is shared with the first bracket side wall 342, which can save space of the bracket 34 and improve the space utilization of the bracket 34, and can also reduce material usage and reduce costs.

[0050] Optionally, see Fig.12 , Fig.13A plurality of pin grooves 3416 are provided on the side of the bracket bottom wall 341 away from the oil cup 22, and the pin grooves 3416 connect the electrode blind hole 3415 with the first wiring hole 3411 and the second wiring hole 3412. The pin 2112 is embedded in the pin groove 3416, and the pin 2112 further extends to the electrode blind hole 3415 through the pin groove 3416. By providing the pin groove 3416 to connect the electrode blind hole 3415 with the first wiring hole 3411 and the second wiring hole 3412, on the one hand, the pin groove 3416 can guide the extension direction of the pin 2112, which is convenient for the assembly and alignment of the pin 2112; on the other hand, the pin groove 3416 forms a protection for the pin 2112, so that the pin 2112 is not easily touched and displaced during the assembly process.

[0051] like Figure 3 , Figure 4 , Figure 11-13 As shown, the atomizing device 100 has a width direction perpendicular to the length direction, and a thickness direction perpendicular to the length direction and the width direction. The dimension of the atomizing device 100 in the width direction is greater than the dimension in the thickness direction. For example, the width direction may be Figure 3 The X-axis direction in the thickness direction can be Figure 4 The Y-axis direction. The first wiring hole 3411 and the second wiring hole 3412 are respectively arranged on both sides of the second air inlet hole 3413 in the thickness direction. In the width direction, the second air inlet hole 3413 is farther away from the first air inlet hole 2222 than the first wiring hole 3411 and the second wiring hole 3412, so that the first wiring hole 3411 and the second wiring hole 3412 are arranged in the vicinity of the projection of the first air inlet hole 2222 on the bracket 34 along the length direction. The first wiring hole 3411 and the second wiring hole 3412 are at least partially misaligned with the second air inlet hole 3413 in the width direction. In a reference plane of the bracket 34 perpendicular to the length direction, the line connecting the geometric centers of the first wiring hole 3411, the second wiring hole 3412 and the second air inlet hole 3413 is a triangle, which can prevent the first wiring hole 3411 and the second wiring hole 3412 from being side by side with the second air inlet hole 3413 in the thickness direction, thereby reducing the size of the atomization device 100 in the thickness direction.

[0052] See also Figure 11-13, there is a gap between the inner wall of the second bracket side wall 343 and the outer wall of the first bracket side wall 342, and the second bracket side wall 343 and the first bracket side wall 342 are nested inside and outside. In the thickness direction, one of the electrode blind holes 3415 and the first wiring hole 3411 are located on the same side of the second air inlet hole 3413, and are arranged within the range of the air inlet cavity 3421, so that the electrode blind hole 3415 does not block the communication of the collection cavity 3431 in the width direction. The remaining electrode blind holes 3415 and the second wiring hole 3412 are located on the same side of the second air inlet hole 3413 and are arranged at the gap. The second bracket side wall 343 is set to at least part of the hole wall of the remaining electrode blind holes 3415, so that part of the hole wall of the electrode blind hole 3415 is shared with the second bracket side wall 343 and the first bracket side wall 342 at the same time, which can save the space of the bracket 34 and improve the space utilization of the bracket 34, and reduce the material consumption and reduce the cost.

For example, the first pin sleeve 223 and the second pin sleeve 224 are respectively arranged on both sides of the first air inlet 2222 in the thickness direction. The pin 2112 passes through the oil cup base 222 through the first pin sleeve 223 and the second pin sleeve 224, and the first pin sleeve 223 and the second pin sleeve 224 are respectively inserted into the first wiring hole 3411 and the second wiring hole 3412. A threading hole 2221 is opened on the oil cup base 222 corresponding to the connection between the first pin sleeve 223 and the second pin sleeve 224, for allowing the pin 2112 to pass through the oil cup base 222. The second pin sleeve 224 accommodates relatively more pins 2112, and two threading holes 2221 can be opened in the corresponding second pin sleeve 224 to facilitate the arrangement of the pins 2112. The first pin sleeve 223 and the second pin sleeve 224 are provided to pass the pins 2112, and the first pin sleeve 223 and the second pin sleeve 224 have a guiding function, which can guide the pins 2112 to pass through the oil cup base 222 and extend to the side of the bracket 34 away from the oil cup 22, thereby improving the assembly efficiency.

[0054] See also Fig.11 , Fig.13The bracket 34 includes a first outlet tube 345 and a second outlet tube 346 connected to the bottom wall 341 of the bracket. The first outlet tube 345 and the second outlet tube 346 are respectively connected to the first wiring hole 3411 and the second wiring hole 3412. The first outlet tube 345 and the second outlet tube 346 are respectively sleeved outside the first pin sleeve 223 and the second pin sleeve 224, so that the pin sleeve and the outlet tube form an inner and outer nested arrangement, which increases the contact area between the two, which can not only make the connection between the bracket 34 and the oil cup 22 more secure, but also enhance the air tightness of the pin 2112. The first outlet pipe 345 and the second outlet pipe 346 extend toward the side where the oil cup base 222 is located. The first outlet pipe 345 and the second outlet pipe 346 are arranged adjacent to the first bracket side wall 342. The first bracket side wall 342 is arranged to be at least a portion of the pipe wall of the first outlet pipe 345 and the second outlet pipe 346, so that part of the pipe wall of the outlet pipe is shared with the first bracket side wall 342, which can save space of the bracket 34 and improve the space utilization of the bracket 34, and can also reduce material usage and reduce costs.

[0055] As shown Figure 8 , Fig.10 As shown, the oil cup 22 includes a sealing flange 225 connected to the oil cup base 222, the sealing flange 225 is arranged around the first pin sleeve 223 and the second pin sleeve 224, and the first bracket side wall 342 abuts the sealing flange 225, which can enhance the air tightness between the bracket 34 and the oil cup 22. A sensor airway groove 2251 is provided on the sealing flange 225, and the airflow sensor 33 is connected to the first air inlet hole 2222 through the collection cavity 3431 and the sensor airway groove 2251, thereby forming a sensor airway independent of the air inlet channel of the atomization device 100, which can enhance the sensitivity of the airflow sensor 33 to airflow changes.

[0056] See also Figure 3 , Figure 8 , Fig.12The bracket 34 includes an air inlet pipe 344 connected to the bottom wall 341 of the bracket, the air inlet pipe 344 is connected to the second air inlet hole 3413, and the air inlet pipe 344 extends to the side away from the oil cup 22, and the air inlet pipe 344 is inserted into the opening of the control circuit board 32. The control component 30 includes an air regulating member 36, and the air regulating member 36 is blocked at one end of the air inlet pipe 344 away from the bottom wall 341 of the bracket. The air regulating member 36 is used to adjust the suction resistance of the atomizing device 100, so that the user can experience different suction resistances. By setting the air inlet pipe 344 to be connected to the second air inlet hole 3413, the air inlet pipe 344 extends to one side of the control circuit board 32, so that the air inlet pipe 344 can cooperate with the air regulating member 36 to adjust the air intake at the second air inlet hole 3413, thereby adjusting the suction resistance of the atomizing device 100. The air regulating member 36 is provided with an air regulating hole 361, which is connected to the outside. The air regulating member 36 is arranged to move relative to the air inlet pipe 344 to change the size of the communicating area between the air regulating hole 361 and the air inlet pipe 344, thereby adjusting the suction resistance of the atomizing device 100. Optionally, the air regulating member 36 is slidably arranged on the base 35 so that the air regulating member 36 can move relative to the air inlet pipe 344. Optionally, a first sealing member 39 is arranged between the air inlet pipe 344 and the air regulating member 36. The first sealing member 39 is sleeved on the air inlet pipe 344 to enhance the air tightness of the connection between the air inlet pipe 344 and the air regulating member 36.

[0057] like Figure 8 As shown, the opening size of the air inlet pipe 344 at one end close to the bracket bottom wall 341 is smaller than the opening size of the air inlet pipe 344 at one end away from the bracket bottom wall 341. Optionally, the cross section of the air inlet pipe 344 perpendicular to the length direction of the atomizing device 100 is substantially rectangular, wherein the larger side extends along the width direction of the atomizing device 100 to match the shape of the atomizing device 100. The opening size of the end of the air inlet pipe 344 close to the bottom wall 341 of the bracket is set to be smaller than the opening size of the end of the air inlet pipe 344 away from the bottom wall 341 of the bracket. On the one hand, the opening size of the end of the air inlet pipe 344 connected to the second air inlet hole 3413 is smaller, which can reduce the opening size of the second air inlet hole 3413 to reduce the space occupied by the second air inlet hole 3413 on the bottom wall 341 of the bracket, thereby reducing the size of the bracket 34; on the other hand, the opening of the end of the air inlet pipe 344 that cooperates with the air regulating member 36 is larger, so that the coverage area of ​​the opening of the air inlet pipe 344 on the air regulating member 36 is large, and the air regulating hole 361 is opened within the coverage range of the air inlet pipe 344. Multiple air regulating holes 361 of different sizes can be arranged within the range, thereby forming multiple air regulating gears, so that the suction resistance adjustment is more accurate. Optionally, the opening size of the air inlet pipe 344 gradually changes along the length direction of the atomization device 100, which can make the airflow in the air inlet pipe 344 flow more smoothly.
