[0025] The present application provides an atomization device. Please refer to Figure 1 , Figure 2 The atomization device 100 can include a control assembly 10 and an atomization assembly 20. The atomization assembly 20 stores an atomization substrate. The atomization assembly 20 is used to heat the atomization substrate to generate aerosol. The atomization assembly 20 is provided with an airflow passage 28, which communicates with external air, and the external air can enter the airflow passage 28 to carry the aerosol out of the airflow passage 28. The control assembly 10 is electrically connected to the atomization assembly 20, and the control assembly 10 is used to control the working state of the atomization assembly 20. For example, the control assembly 10 can control the atomization assembly 20 to heat the atomization substrate to generate aerosol or stop heating according to the user's puffing action. The atomization assembly 20 and the control assembly 10 can be fixedly connected or detachably connected. When the atomization assembly 20 and the control assembly 10 are detachably connected, if the remaining amount of the atomization substrate in the atomization assembly 20 is less than a preset value, the user can conveniently separate the atomization assembly 20 from the control assembly 10, and the atomization device 100 continues to be used after replacing the atomization assembly 20, so that the control assembly 10 can be used multiple times, which is beneficial to reduce the user's use cost.

[0026] Referring to Figure 2 In an embodiment, the atomization assembly 20 comprises a mouthpiece 21, a housing 22, a liquid storage 23, and an atomization core 24. The liquid storage 23 is installed in the housing 22, and the liquid storage 23 is used to store an atomization substrate. The atomization substrate can be stored in the liquid storage 23 in the form of a liquid, or can be stored by means of a storage medium. For example, the liquid storage 23 is provided with a liquid storage piece 25, the liquid storage piece 25 is filled in the liquid storage 23, the liquid storage piece 25 is wrapped outside the atomization core 24, the liquid storage piece 25 is a porous medium such as fiber cotton, and the liquid storage piece 25 can adsorb the atomization substrate, so as to store the atomization substrate in the liquid storage 23. A part of the airflow channel 28 is arranged in the liquid storage 23. For example, an air duct can be arranged in the liquid storage 23, and the air duct forms a part of the airflow channel 28; for another example, a through hole is formed in the liquid storage piece 25, and the through hole forms a part of the airflow channel 28. The atomization core 24 is installed on the airflow channel 28 in the liquid storage 23. The atomization substrate can be delivered to the atomization core 24, so that the atomization core 24 can heat the atomization substrate to generate an aerosol. The atomization core 24 can comprise a heating piece 241, a liquid guide piece 242, and an atomization tube 243. The liquid guide piece 242 is used to deliver the atomization substrate to the heating piece 241, the heating piece 241 is used to generate heat by electrification, and the heating piece 241 heats the atomization substrate to atomize it. Exemplarily, the liquid guide piece 242 is a cotton liquid guide piece, the liquid guide piece 242 is wrapped around the periphery of the heating piece 241, and the liquid guide piece 242 is at least partially accommodated in the atomization tube 243, so that the heating piece 241, the liquid guide piece 242, and the atomization tube 243 form a relatively independent module, and then the atomization tube 243 is assembled on the airflow channel 28, so as to realize the modular assembly of the atomization core 24, and the production efficiency can be improved. The mouthpiece 21 is connected to one end of the housing 22. The mouthpiece 21 can be integrally formed with the housing 22, that is, the mouthpiece 21 and the housing 22 are an integral structure; or the mouthpiece 21 and the housing 22 can be separately processed and then assembled and connected, that is, the mouthpiece 21 and the housing 22 are a split structure. A part of the airflow channel 28 is arranged in the mouthpiece 21, and the mouthpiece 21 communicates with the atomization core 24, so that the aerosol can be output through the airflow channel 28.

[0027] In an embodiment, as Figure 2 shown, the atomization assembly 20 further comprises a first liquid absorption piece 26, and the first liquid absorption piece 26 is installed on the airflow channel 28 close to the mouthpiece 21. The material of the first liquid absorption piece 26 can be fiber cotton with good adsorption capacity, and the first liquid absorption piece 26 can adsorb condensed liquid in the aerosol or unatomized atomization substrate mixed in the aerosol, so as to improve the taste of the aerosol. The atomization assembly 20 can further comprise a second liquid absorption piece 27, and the second liquid absorption piece 27 is installed on the airflow channel 28 away from the end of the mouthpiece 21, and the second liquid absorption piece 27 is used to adsorb the atomization substrate seeping from the liquid storage 23, so as to prevent the atomization substrate from leaking.

[0028] Referring to Figure 2、 Figure 3 The control assembly 10 comprises a circuit board 11, an airflow sensor 12 and a cover 13. The circuit board 11 can be mounted at the end of the liquid storage 23 away from the mouthpiece 21. The circuit board 11 can also be mounted on other components, for example, mounted in the shell 22 through a support (not shown in the figure). The cover 13 is arranged on one side of the circuit board 11. The cover 13 can be connected to the shell 22. When the circuit board 11 is mounted in the shell 22 through the support, the cover 13 can also be connected to the support. Relatively speaking, the circuit board 11 is arranged to be mounted on the liquid storage 23, and the cover 13 is connected to the shell 22, so that the components of the atomization assembly 20 can be used to fix the circuit board 11 and the cover 13, without the need to arrange additional fixing components, which can reduce the number of components of the atomization device 100 and is conducive to reducing the production cost. The cover 13 and the circuit board 11 enclose a containing space 134, and the airflow sensor 12 is accommodated in the containing space 134. The airflow sensor 12 is arranged on the surface of the circuit board 11. The airflow sensor 12 can be welded on the circuit board 11. The cover 13 is provided with a first air hole 135, and the first air hole 135 communicates the containing space 134 with the external air. The external air can enter the containing space 134 through the first air hole 135, so that the pressure on one side of the airflow sensor 12 is equal to the pressure of the external air. The circuit board 11 is provided with a second air hole 111, and the airflow sensor 12 communicates with the airflow channel 28 of the atomization assembly 20 through the second air hole 111, so that the pressure on the other side of the airflow sensor 12 is equal to the pressure of the gas in the airflow channel 28. The control assembly 10 can further comprise a power supply 18 for providing electric energy for the operation of the atomization device 100. The power supply 18 can be a battery, and the battery can be a rechargeable battery. The circuit board 11 is electrically connected with the power supply 18, the heating element 241 and the airflow sensor 12. When the user sucks the atomization device 100, the air pressure in the airflow channel 28 changes. The airflow sensor 12 senses the change of the airflow through the air pressure difference and generates a control signal, which is used to change the conduction state between the heating element 241 and the power supply 18, so as to control the heating element 241 to heat or stop heating.

[0029] The atomization device 100 provided in the present application forms the containing space 134 for mounting the airflow sensor 12 by enclosing the cover 13 and the circuit board 11. Since a separate silica gel seat is not needed, the number of materials of the control assembly 10 can be reduced, the assembly steps are simplified, and the cost of the control assembly 10 is reduced.

[0030] The material of the cover 13 can be plastic. The cover 13 can directly abut one side of the circuit board 11, so that the cover 13 and the circuit board 11 are interference fit, thereby enhancing the airtightness of the containing space 134 and improving the sensitivity of the airflow sensor 12.

[0031] The cover 13 can also indirectly abut against one side of the circuit board 11 through other components. In an embodiment, as shown in Figure 3 The control assembly 10 includes a first seal 14 that is sealed between the circuit board 11 and the cover 13 and is arranged around the periphery of the airflow sensor 12. The first seal 14 can be made of silicone or rubber or other material that has good elastic deformation capability. The first seal 14 is arranged to be sealed at the joint between the circuit board 11 and the cover 13, and the elastic deformation of the first seal 14 can be used to seal the gap between the circuit board 11 and the cover 13, thereby enhancing the airtightness of the accommodation space 134, reducing the volume of air in the accommodation space 134, and improving the sensitivity of the airflow sensor 12.

[0032] Please refer to Figure 4 , Figure 5 The cover 13 includes a bottom wall 131 and a first side wall 132 that is in the form of a hollow cylinder and is connected to the bottom wall 131. The circuit board 11, the first side wall 132, and the bottom wall 131 form an accommodation space 134, and the bottom wall 131 is provided with a first air hole 135.

[0033] The first seal 14 can be in the form of a ring-shaped sheet that is clamped between the first side wall 132 and the circuit board 11, thereby sealing the gap between the circuit board 11 and the first side wall 132. In an embodiment, as shown in Figure 4 The first seal 14 is in the form of a hollow cylinder and is accommodated in the accommodation space 134, with one end of the first seal 14 abutting the bottom wall 131 and the other end abutting the circuit board 11. The first seal 14 is arranged to be accommodated in the accommodation space 134, so that the first side wall 132 can be used for assembly positioning of the first seal 14, thereby facilitating assembly of the first seal 14 and improving assembly efficiency.

[0034] Please refer to Figure 2 , Figure 3 , Figure 6In an embodiment, the control assembly 10 comprises a power adjusting member 15 and an air intake adjusting member 16. The power adjusting member 15 is used to adjust the power of the atomization assembly 20, so that the user can experience the taste of aerosol generated by atomization of different power, and the individualized needs of the user can be met. The air intake adjusting member 16 is used to adjust the air intake amount of the airflow channel 28, so as to change the suction resistance of the atomization device 100, so that the user can experience different suction resistance, and the individualized needs of the user can be met. One end of the power adjusting member 15 is in sliding connection with the circuit board 11, and the other end is connected with the air intake adjusting member 16. The cover 13 is provided with a first air inlet hole 136 and a guide hole 137. Specifically, the first air inlet hole 136 and the guide hole 137 can be provided on the bottom wall 131. The first air inlet hole 136 communicates the airflow channel 28 with the external air, so that the external air can enter the airflow channel 28 through the first air inlet hole 136. The air intake adjusting member 16 is arranged in the guide hole 137, and the guide hole 137 can limit the movement path of the air intake adjusting member 16. The air intake adjusting member 16 can slide along the guide hole 137 under external action and change the communication area between the first air inlet hole 136 and the external air. Specifically, when the air intake adjusting member 16 slides along the guide hole 137, the air intake adjusting member 16 can change the shielding area of the first air inlet hole 136, so as to change the communication area between the first air inlet hole 136 and the external air, so as to adjust the air intake amount of the airflow channel 28. The air intake adjusting member 16 can drive the power adjusting member 15 to move, so as to adjust the power of the atomization assembly 20 while adjusting the air intake amount of the airflow channel 28. The air intake adjusting member 16 drives the power adjusting member 15 to move, so as to synchronously adjust the air intake amount of the airflow channel 28 and the power of the atomization assembly 20. On the one hand, the air intake amount and the power are matched, so as to improve the taste of the aerosol; on the other hand, the air intake amount and the power can be adjusted at the same time through the air intake adjusting member 16, without the need to adjust the air intake amount and the power respectively, which can reduce the number of adjusting components, reduce the production cost, facilitate the control operation of the atomization device 100, and be beneficial to improving the user experience.

[0035] The material of the air intake adjusting member 16 can be plastic. The air intake adjusting member 16 can directly abut one side of the cover 13, so that the air intake adjusting member 16 is in interference fit with the cover 13, thereby enhancing the airtightness of the connection between the air intake adjusting member 16 and the cover 13, and improving the accuracy of air adjustment.

[0036] The air intake adjusting member 16 can also indirectly abut one side of the cover 13 through other components. In an embodiment, as shown in FIG. 6, the air intake adjusting member 16 is provided with a connecting member 161. The connecting member 161 is in sliding connection with the power adjusting member 15, and the air intake adjusting member 16 is in sliding connection with the cover 13 through the connecting member 161. The connecting member 161 can be a rod, and the air intake adjusting member 16 can be a sleeve. The air intake adjusting member 16 can be sleeved on the connecting member 161, and the connecting member 161 can slide in the air intake adjusting member 16. The air intake adjusting member 16 can be directly connected with the cover 13, or indirectly connected with the cover 13 through other components. Figure 3As shown, the control assembly 10 comprises a second seal 17 sealing at the joint of the air intake adjusting member 16 and the cover 13. The second seal 17 can be made of silica gel or rubber or other material with good elastic deformation capability. The second seal 17 is arranged to seal at the joint of the air intake adjusting member 16 and the cover 13, and the elastic deformation of the second seal 17 can be used to seal the gap between the air intake adjusting member 16 and the cover 13, so as to improve the accuracy of air adjustment and realize the tactile feedback of air adjustment.

[0037] The second seal 17 can be connected to the cover 13. For example, the second seal 17 is arranged around the outer periphery of the first air intake hole 136 and the guide hole 137, and the second seal 17 is clamped between the air intake adjusting member 16 and the cover 13 to seal the gap between the air intake adjusting member 16 and the cover 13. Please refer to Figure 3 In an embodiment, the second seal 17 is provided with a first through hole 171, the air intake adjusting member 16 is arranged in the first through hole 171, and the second seal 17 is connected to the air intake adjusting member 16. Since the air intake adjusting member 16 slides along the guide hole 137 to adjust the air intake and power, the projected area of the air intake adjusting member 16 on the cover 13 is smaller than the distribution area of the first air intake hole 136 and the guide hole 137. Compared with the arrangement of the second seal 17 around the outer periphery of the first air intake hole 136 and the guide hole 137, the arrangement of the second seal 17 connected to the air intake adjusting member 16 can reduce the area of the second seal 17, thereby reducing the amount of material and being conducive to reducing production costs.

[0038] The bottom wall 131 can be flat, so that one end of the air intake adjusting member 16 can protrude from the bottom wall 131 to facilitate the user to hold the air intake adjusting member 16 to adjust the air intake and power. In an embodiment, as shown in Figures 3-5 As shown, part of the bottom wall 131 protrudes towards the direction close to the circuit board 11, and forms a receiving groove 138 on the side away from the circuit board 11, the first air intake hole 136 and the guide hole 137 are located in the receiving groove 138, and the air intake adjusting member 16 is at least partially received in the receiving groove 138. In this way, the receiving groove 138 is formed on the bottom wall 131, and one end of the air intake adjusting member 16 can be flush with the bottom wall 131, so as to facilitate hiding the end of the air intake adjusting member 16 in the receiving groove 138, thereby reducing the influence of the exposed air intake adjusting member 16 on the appearance of the atomization device 100.

[0039] In one embodiment, there is one first air inlet 136, which is elongated and extends along the sliding direction of the air intake regulator 16. With this configuration, when the air intake regulator 16 slides along the guide hole 137 under external influence, the air intake regulator 16 can continuously change the area of ​​its obstruction of the first air inlet 136, thereby continuously changing the communication area between the first air inlet 136 and the external air, achieving stepless adjustment of the air intake volume of the airflow channel 28.

[0040] In one embodiment, there are multiple first air inlets 136, which are arranged at intervals along the sliding direction of the air intake regulator 16. The opening areas of each first air inlet 136 can be the same or different. With this configuration, when the air intake regulator 16 slides along the guide hole 137 under external action, the air intake regulator 16 can selectively block a portion of the first air inlets 136, thereby changing the communication area between the first air inlets 136 and the external air in a preset manner, and realizing the adjustment of the air intake level of the airflow channel 28.

[0041] Please see Figure 3 , Figure 4 In one embodiment, the cover 13 further includes a second sidewall 133. The first sidewall 132 and the second sidewall 133 are connected to the bottom wall 131. The circuit board 11, the first sidewall 132, and the bottom wall 131 enclose a receiving space 134. The second sidewall 133 surrounds the outer periphery of the first sidewall 132. The circuit board 11, the first sidewall 132, the second sidewall 133, and the bottom wall 131 enclose an air intake cavity 139. The cover 13 and the circuit board 11 can directly enclose to form the air intake cavity 139; or, when the circuit board 11 is installed on the liquid storage tank 23, the cover 13, the circuit board 11, and the liquid storage tank 23 can also enclose to form the air intake cavity 139. A second air inlet 112 is provided on the circuit board 11, which connects the air intake chamber 139 and the airflow channel 28. A first air inlet 136 is provided on the bottom wall 131, and the orthographic projection of the first air inlet 136 on the circuit board 11 falls outside the second air inlet 112. This arrangement allows the second air inlet 112 to be located at one end of the circuit board 11 closer to the airflow channel 28, while the orthographic projection of the first air inlet 136 on the circuit board 11 falls at the other end of the circuit board 11 away from the second air inlet 112. Since the atomizing core 24 is mounted on the airflow channel 28, the first air inlet 136 can be moved away from the airflow channel 28, and thus away from the atomizing core 24. The air intake chamber 139 forms a buffer space before external air enters the airflow channel 28, which can prevent external air from directly hitting the atomizing core 24, thereby improving the taste of the aerosol.

[0042] The above merely describes some embodiments of the present application, and does not limit the protection scope of the present application, and any equivalent device or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
