[0028] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0029] This application provides an atomization device. Please refer to Figures 1 - 6 , the atomization device 100 may include a housing assembly 10, an atomization assembly 20, and a control assembly 30. The housing assembly 10 has a receiving cavity 14, and the atomization assembly 20 is installed in the receiving cavity 14. The atomization assembly 20 is provided with an oil storage cavity 24, and the oil storage cavity 24 stores an atomization matrix. The atomization assembly 20 is used to atomize the atomization matrix into an aerosol. The control assembly 30 is used to control the working state of the atomization assembly 20. For example, the control assembly 30 can control the atomization assembly 20 to heat the atomization matrix to generate an aerosol or stop heating according to the user's sucking action.

[0030] As Figures 1 - 4 shown, the housing assembly 10 includes a first housing 11, a second housing 12, and a mouthpiece housing 13. The first housing 11 has an inner space, and the second housing 12 and the mouthpiece housing 13 enclose the receiving cavity 14 with the first housing 11, so that the number of components of the housing assembly 10 is small, which can simplify the assembly process of the housing assembly 10 and improve the assembly efficiency. The atomization device 100 has a length direction. Exemplarily, the length direction can be Figure 4in the Z-axis direction. A first housing 11 is provided with a first mounting hole 111 on one side perpendicular to the length direction, and a second housing 12 is mounted in the first mounting hole 111. The first housing 11 is provided with a second mounting hole 112 at one end in the length direction, and a nozzle housing 13 is mounted in the second mounting hole 112. Optionally, the connection manner between the second housing 12, the nozzle housing 13 and the first housing 11 can be snap connection, bonding or screw connection. The nozzle housing 13 can be used for a user to perform a suction action. The nozzle housing 13 is communicated with the atomization assembly 20 so that the aerosol generated by atomizing the atomization assembly 20 can reach one end where the user inhales.

[0031] Generally speaking, to ensure the overall appearance effect of the housing assembly 10, the area of the bottom of the housing assembly 10 is usually smaller than the area of the side of the housing assembly 10. For example, the area of the bottom of the first housing 11 is set to be smaller than the area of the side of the first housing 11. The first mounting hole 111 is opened on one side of the first housing 11 perpendicular to the length direction. The components in the accommodating cavity 14 can be loaded through the first mounting hole 111. Compared with the first mounting hole 111 being opened in other parts, such as being opened at the end in the length direction of the first housing 11 (specifically, it can be the bottom), it can make the first mounting hole 111 have a relatively large opening area, thereby providing a relatively large operating space, being beneficial to the assembly operation, and further improving the assembly efficiency.

[0032] The housing assembly 10 is generally substantially cylindrical in shape. For example, the housing assembly 10 can be in the shape of a cylinder or an ellipsoid cylinder, that is, the cross-section of the housing assembly 10 perpendicular to the length direction is circular or elliptical. Or, as Figure 2 , Figure 6 shown, the cross-section of the housing assembly 10 perpendicular to the length direction is substantially rectangular. Specifically, the atomization device 100 has a width direction perpendicular to the length direction and a thickness direction perpendicular to the length direction and the width direction. Exemplarily, the width direction can be Figure 6 the X-axis direction in Figure 6 and the thickness direction can be the Y-axis direction in

[0033] Please refer to Figure 3 , Figure 4, the atomization assembly 20 may include an atomization core 21 and an oil cup 22. The oil cup 22 is disposed in the accommodation cavity 14. The atomization core 21 is installed in the oil cup 22, and an atomization matrix is stored in the oil cup 22. The atomization core 21 is used to heat the atomization matrix to generate an aerosol. Specifically, the oil cup 22 has an oil storage cavity 24, and the atomization core 21 is installed in the oil storage cavity 24, and the oil storage cavity 24 is used to store the atomization matrix. The atomization matrix can be stored in the oil storage cavity 24 in the form of a liquid or with the aid of a storage medium. For example, the atomization assembly 20 further includes an oil storage member 23. The oil storage member 23 is filled in the oil storage cavity 24, the oil storage member 23 wraps around the atomization core 21, and the oil storage member 23 is a porous medium, such as fiber cotton. The oil storage member 23 can adsorb the atomization matrix, thereby storing the atomization matrix in the oil storage cavity 24.

[0034] It can be understood that the atomization core 21 at least includes a heating element and a liquid guiding element. Among them, the function of the liquid guiding element is to transfer the atomization matrix to the heating element, and the function of the heating element is to generate heat when powered on, so as to heat the atomization matrix to atomize it. Exemplarily, the heating element is a cylindrical MESH heating element (not shown in the figure), and the liquid guiding element is a cylindrical cotton liquid guiding element. The liquid guiding element wraps around the outer circumferential surface of the MESH heating element. The oil cup 22 may include an oil cup housing 221, an oil cup base 222, and an oil cup upper cover 223. The oil cup base 222 is disposed at one end of the oil cup housing 221 along the length direction, and the oil cup upper cover 223 is disposed at the end of the oil cup housing 221 away from the oil cup base 222 along the length direction. The oil cup housing 221, the oil cup base 222, and the oil cup upper cover 223 enclose to form the oil storage cavity 24.

[0035] As Figures 2 - 5 shown, the control assembly 30 may include a battery 31, a control circuit board 32, an air flow sensor 33, and a sensor seal 34 installed in the accommodation cavity 14. The battery 31 is used to provide electrical energy for the operation of the atomization device 100. The air flow sensor 33 is configured to control the on-off state of the electrical connection between the atomization assembly 20 and the battery 31 according to the user's suction action. Specifically, when the user inhales through the nozzle housing 13, the air flow sensor 33 senses the change in air flow, and the air flow sensor 33 controls the atomization assembly 20 and the battery 31 to conduct, and the atomization assembly 20 can heat the atomization matrix to generate an aerosol; when the user stops inhaling, the air flow sensor 33 does not sense the change in air flow within a preset time period, and the air flow sensor 33 controls the atomization assembly 20 and the battery 31 to disconnect, and the atomization assembly 20 stops heating.

[0036] Please continue to refer to Figures 2 - 5, the control component 30 further includes a control member 35. The control circuit board 32 is provided with an adjusting member 321, and the adjusting member 321 can be used to adjust the heating power of the atomizing core 21. The oil cup base 222 is provided with a first air inlet hole 228, and the sensor seal 34 is provided with a second air inlet hole 341, and the second air inlet hole 341 communicates with the first air inlet hole 228. An air adjustment hole 351 is provided on the control member 35. The control member 35 is connected to the adjusting member 321, and the control member 35 covers one side of the second air inlet hole 341. When the control member 35 moves relative to the sensor seal 34, the communication area between the second air inlet hole 341 and the air adjustment hole 351 can be changed to adjust the air intake of the atomizing device 100, thereby adjusting the draw resistance of the atomizing device 100, so that the user can experience different draw resistances; and the control member 35 can synchronously drive the adjusting member 321 to move to adjust the heating power of the atomizing core 21, so that the heating power matches the air intake. A gas adjustment seal 36 can be provided between the sensor seal 34 and the control member 35. The gas adjustment seal 36 is sleeved on the sensor seal 34 to enhance the airtightness at the connection between the sensor seal 34 and the control member 35.

[0037] Please refer to Figures 2 - 6 , the atomizing device 100 may further include a display component 40, a liquid absorbing member 50 and a shielding member 60. The display component 40 is installed in the accommodation cavity 14, and the display component 40 is used to display information of the atomizing device 100. Exemplarily, the information displayed by the display component 40 can be one or more of the power information, heating mode, heating power, atomizing matrix stock and brand logo of the atomizing device 100. The display component 40 may include a display screen 41 and a display screen circuit board 42. The display screen 41 is electrically connected to the display screen circuit board 42, and the display screen circuit board 42 is used to control the information display of the display screen 41.

[0038] The liquid absorbing member 50 and the shielding member 60 are installed between the atomizing component 20 and the mouthpiece housing 13. The liquid absorbing member 50 is a porous medium, such as fiber cotton. The liquid absorbing member 50 is used to adsorb the condensate or unatomized atomizing matrix in the aerosol to improve the taste of the aerosol. The shielding member 60 is arranged to be light-impermeable. When the mouthpiece housing 13 is made of a transparent material, the shielding member 60 can prevent the user from observing the liquid absorbing member 50 through the mouthpiece housing 13, so as to avoid the discoloration of the liquid absorbing member 50 after adsorbing the condensate or atomizing matrix and affecting the appearance of the product.

[0039] In the related art, multiple components of the atomizing device need to be separately assembled into the housing assembly. Due to the large number of components, the assembly efficiency is not high.

[0040] Please refer to Figure 3 、 Figure 7, the control component 30 includes a first bracket 37 and a second bracket 38. The first bracket 37 and the second bracket 38 are disposed in the accommodation cavity 14. The first bracket 37 is disposed on one side in the vertical length direction of the oil cup housing 221, and the first bracket 37 and the oil cup housing 221 enclose a first installation cavity 371. The second bracket 38 is disposed along the length direction at one end of the oil cup base 222 away from the oil cup housing 221, and the second bracket 38 and the oil cup base 222 enclose a second installation cavity 381. By providing the first bracket 37 and the second bracket 38 and the oil cup 22 to form two installation cavities, the installation cavities can be used to accommodate at least part of the components, and at least part of the components are installed in the installation cavities, so that a plurality of components form an assembly module, and modular assembly can be adopted. The second installation cavity 381 communicates with the first installation cavity 371. Providing the second installation cavity 381 to communicate with the first installation cavity 371 can facilitate the connection between the components in the second installation cavity 381 and the components in the first installation cavity 371, so that the connecting members (such as connecting wires) between the components can be located in the installation cavity, which is beneficial to integrating the connecting members into the assembly module and facilitating modular assembly. The first bracket 37 and the second bracket 38 are connected as an integral part. Providing the first bracket 37 and the second bracket 38 to be connected as an integral part enables the first bracket 37 and the second bracket 38 to be integrally processed and formed, which can reduce the number of components during assembly, and because the integral structure of the first bracket 37 and the second bracket 38 has good integrity, it can enhance the integrity of the assembly module, facilitate modular assembly, and thus improve the assembly efficiency of the atomization device 100.

[0041] The battery 31 can be installed in the second installation cavity 381. For example, the battery 31 is installed on the second bracket 38, and the battery 31 extends along the width direction. Or, as Figure 4 , Figure 6 shown, the battery 31 is installed in the first installation cavity 371. The first bracket 37 is provided with an installation groove 372 in the vertical length direction, and the oil cup housing 221 covers one side of the installation groove 372 to enclose the first installation cavity 371 with the first bracket 37. By providing the installation groove 372 in the vertical length direction of the first bracket 37 and the oil cup housing 221 covering one side of the installation groove 372 to form the first installation cavity 371, since the first bracket 37 is disposed on one side in the vertical length direction of the oil cup housing 221, the first installation cavity 371 can extend along the length direction, and the length direction has a larger size relative to other directions (such as the width direction), so a first installation cavity 371 with a larger size can be arranged to accommodate a battery 31 with a larger volume, which can improve the battery life of the atomization device 100.

[0042] Please refer to Figure 4 、 Figure 5, the control circuit board 32, the airflow sensor 33, and the sensor seal 34 are installed in the second installation cavity 381. The airflow sensor 33 is installed on the control circuit board 32. The sensor seal 34 covers one side of the airflow sensor 33 along the length direction. The sensor seal 34 is inserted into the oil cup base 222 and connected to the second bracket 38. Installing the airflow sensor 33 and the sensor seal 34 in the second installation cavity 381, and inserting the sensor seal 34 into the oil cup base 222 and connecting it to the second bracket 38, so that the control circuit board 32, the airflow sensor 33, and the sensor seal 34 are integrated into the assembly module formed by the first bracket 37 and the second bracket 38, which can increase the integration degree of the assembly module, reduce the number of components during assembly, and thus improve the assembly efficiency of the atomizing device 100.

[0043] As Figure 4 shown, the control member 35 is slidably arranged on the second bracket 38. When the control member 35 slides along the second bracket 38, the intake air volume of the atomizing device 100 and the heating power of the atomizing core 21 can be synchronously adjusted so that the heating power matches the intake air volume. Arranging the control member 35 slidably on the second bracket 38 and further integrating the control member 35 into the assembly module formed by the first bracket 37 and the second bracket 38 can increase the integration degree of the assembly module and reduce the number of components during assembly.

[0044] Please refer to Figure 3 , Figure 6 , the display component 40 includes a third bracket 43. The third bracket 43 is connected to the first bracket 37. The third bracket 43 covers the side of the first installation cavity 371 away from the oil cup housing 221 to limit the battery 31 in the first installation cavity 371. The connection method between the third bracket 43 and the first bracket 37 can be snap connection, bonding, or threaded connection. Setting the third bracket 43 to be connected to the first bracket 37 and the third bracket 43 limiting the battery 31 in the first installation cavity 371 can prevent the battery 31 from shifting, making it difficult for the connection wires between the battery 31 and other components to fall off, and can improve the reliability of the battery 31 to provide electrical energy for the atomizing device 100.

[0045] Please refer to Figure 8 , the oil cup 22 further includes a first limiting portion 224 and a second limiting portion 225. The first limiting portion 224 and the second limiting portion 225 are connected to one side of the oil cup housing 221 along the vertical length direction. The first limiting portion 224 and the second limiting portion 225 are respectively located at opposite ends in the length direction of the oil cup housing 221. The battery 31 abuts against the first limiting portion 224 and the second limiting portion 225 respectively, which can further prevent the battery 31 from shifting, making it difficult for the connection wires between the battery 31 and other components to fall off, and thus improving the reliability of the battery 31 to provide electrical energy for the atomizing device 100.

[0046] AsFigure 3 , Figure 6 As shown in Figure 6 , the display circuit board 42 is installed on the side of the third bracket 43 away from the battery 31, and the display screen 41 is stacked on the display circuit board 42. The display circuit board 42 is installed on the third bracket 43, so that the third bracket 43 can not only limit the displacement of the battery 31, but also serve as the mounting bracket for the display circuit board 42. Since there is no need to set up an independent mounting bracket for installing the display circuit board 42, the number of components of the atomizing device 100 can be reduced, thereby improving the assembly efficiency of the atomizing device 100.

[0047] Please refer to Figure 3 , Figure 6 , the display component 40 further includes a display screen frame 44 and a lens 45. The display screen frame 44 is connected to the third bracket 43. The display screen frame 44 surrounds the outer periphery of the display screen 41 and the display circuit board 42, and the lens 45 is installed on the side of the display screen frame 44 away from the display screen 41. The connection method between the display screen frame 44 and the third bracket 43 can be snap connection, bonding or screw connection. By setting the display screen frame 44, the display screen frame 44 is connected to the third bracket 43, and the lens 45 is installed on the display screen frame 44, and the components of the display component 40 are further integrated into the assembly module formed by the first bracket 37 and the second bracket 38, which can increase the integration degree of the assembly module and reduce the number of components during assembly, thereby improving the assembly efficiency of the atomizing device 100.

[0048] As mentioned above, the cross-section of the housing assembly 10 in the direction perpendicular to the length direction can be circular, elliptical or substantially rectangular. As Figure 6 shown, when the cross-section of the housing assembly 10 in the direction perpendicular to the length direction is substantially rectangular, the first bracket 37 is arranged on one side of the width direction of the oil cup housing 221. Since the size of the atomizing device 100 in the width direction is larger than that in the thickness direction, a first installation cavity 371 with a larger size can be arranged, so as to accommodate a battery 31 with a larger volume, and the endurance of the atomizing device 100 can be improved.

[0049] Please refer to Figure 4 , Figure 9, the oil cup 22 includes an air duct 226. The upper cover 223 of the oil cup is provided with an air outlet 229. The air duct 226 is accommodated in the oil cup housing 221, and the air duct 226 is connected to the position where the air outlet 229 of the upper cover 223 of the oil cup is opened. The air duct 226 communicates the atomizing core 21 with the nozzle housing 13, so that the aerosol generated by heating the atomizing core 21 can be transmitted to the nozzle housing 13 through the air duct 226. On one side of the upper cover 223 of the oil cup away from the air duct 226, there is a reflux groove 227. The reflux groove 227 communicates with the air outlet 229 and the air duct 226. The liquid absorbing member 50 is covered on one side of the reflux groove 227. By arranging the liquid absorbing member 50 to cover one side of the reflux groove 227, when the liquid absorbing member 50 adsorbs a large amount of condensed liquid or unatomized atomizing matrix, the condensed liquid or atomizing matrix can flow back through the reflux groove 227 and the air duct 226, thereby preventing the leakage of the condensed liquid or atomizing matrix.

[0050] As Figure 10 shown, the reflux groove 227 includes a main reflux groove 227A and a plurality of secondary reflux grooves 227B. The main reflux groove 227A extends in the width direction. The plurality of secondary reflux grooves 227B are arranged at intervals on opposite sides in the thickness direction of the main reflux groove 227A, and the secondary reflux grooves 227B communicate with the main reflux groove 227A. By arranging a plurality of secondary reflux grooves 227B on opposite sides in the thickness direction of the main reflux groove 227A, the reflux groove 227 can be distributed in a larger area on the upper cover 223 of the oil cup, so as to guide the timely reflux of the condensed liquid or atomizing matrix in each area, prevent the condensed liquid or atomizing matrix from accumulating in a local area on the upper cover 223 of the oil cup, and further reduce the risk of leakage of the condensed liquid or atomizing matrix.
