[0026] Please refer to Figure 1 and Figure 2 The present application provides an aerosol generating device, which can be used for atomizing an aerosol-generating substrate. The aerosol generating device includes a housing assembly 10 , a light guide bracket 30 , and a control circuit board 50 .

[0027] The housing assembly 10 is provided with a light-transmitting area 13. In one embodiment, the side wall of the housing assembly 10 is provided with a light-transmitting area 13. Figure 1 and Figure 2 In the embodiment of the present invention, the housing assembly 10 includes a first housing 14 and a bottom housing 15, the first housing 14 and the bottom housing 15 are detachably connected, and a light-transmitting area 13 is provided on the side wall of the first housing 14. In other embodiments, the first housing 14 and the bottom housing 15 may also be integrally formed. The light-transmitting area 13 facilitates the light effect to be seen from the appearance of the aerosol generating device.

[0028] In one embodiment, the light-transmitting area 13 is made of a fully transparent or translucent material, and the entire housing assembly 10 can be made of a fully transparent or translucent material; or a portion of the housing assembly 10 is made of a fully transparent or translucent material, and another portion of the housing assembly 10 is made of an opaque material. For example, the first shell 14 of the housing assembly 10 can be made of a semi-transparent and semi-opaque first shell 14 using a two-color injection molding process. In other embodiments, the light-transmitting area 13 can also be a light-transmitting opening that passes through the housing assembly 10.

[0029] like Figure 1 and Figure 3As shown, the light guide bracket 30 is disposed inside the housing assembly 10, and the light guide bracket 30 can be configured as a fully transparent or translucent light guide bracket 30. The side wall of the light guide bracket 30 includes a first light guide wall 31 and a second light guide wall 32 connected to each other, and the second light guide wall 32 faces the light transmission area 13, that is, the light on the second light guide wall 32 can be transmitted to the outside of the housing assembly 10 through the light transmission area 13.

[0030] A light emitting member 20 is disposed on the first surface 51 of the control circuit board 50, and the first surface 51 of the control circuit board 50 is disposed opposite to the first light guide wall 31 of the light guide bracket 30. The light emitting member 20 irradiates the first light guide wall 31, and the first light guide wall 31 can transmit the light to the second light guide wall 32. The light emitting member 20 of the light guide bracket 30 can have a certain gap with the first light guide wall 31, and the light emitting member 20 of the light guide bracket 30 can also contact the first light guide wall 31, as long as the light emitted by the light emitting member 20 can irradiate the first light guide wall 31.

[0031] The aerosol generating device of the present application directly irradiates the light-emitting component 20 on the first light-guiding wall 31 of the light-guiding bracket 30. The first light-guiding wall 31 can transmit the light to the second light-guiding wall 32, and the second light-guiding wall 32 transmits the light from the light-transmitting area 13. The light-emitting component 20 does not directly irradiate the second light-guiding wall 32, but irradiates the first light-guiding wall 31 to guide the light to the second light-guiding wall 32. This can prevent the light-emitting component 20 from directly irradiating the second light-guiding wall 32, resulting in bright areas where the second light-guiding wall 32 directly irradiates, and dark areas where the light-guiding wall 32 does not directly irradiate. The light is transmitted from the first light-guiding wall 31 to the second light-guiding wall 32, which can make the light at the film 40 more uniform, and can achieve a uniform bright effect on the appearance of the aerosol generating device. In the present application, the uniform bright effect means that the difference in the brightness intensity displayed at different positions of the second light-guiding wall 32 is small, and it is difficult to observe the difference in brightness intensity with the naked eye.

[0032] Furthermore, compared to the existing structure of lighting from the bottom of the bracket, the light guide bracket 30 finally guides the light to the second light guide wall 32. Compared to the solution of only forming an aperture at the bottom of the bracket, the second light guide wall 32 can display a large area of ​​light, thereby increasing the illumination area and improving the cool appearance.

[0033] In one embodiment, the aerosol generating device may further include a film 40, and the film 40 is disposed on the second light guide wall 32. The film 40 may be disposed on the outer surface of the second light guide wall 32 in the form of a single-sided adhesive. The film 40 may be made of a fully light-transmitting or semi-transmitting material, for example. For example, in one embodiment, the film 40 is configured as a film 40 made of polyethylene terephthalate (PET). Specifically, it may be a translucent milky white PET sticker. Since the PET material has the characteristic of uniform light conduction compared to ordinary stickers, it is beneficial to achieve a uniform bright effect on the appearance of the aerosol generating device. In addition, patterns or texts may be designed on the film 40 for aesthetics.

[0034] In one embodiment, a first installation position 11 may be provided inside the housing assembly 10 , and the first installation position 11 is used to install the atomization device 60 .

[0035] like Figure 1 and Figure 2 As shown, the atomizing device 60 is a device for atomizing an aerosol generating matrix to generate an aerosol. Generally, the interior of the atomizing device 60 includes a second shell 61, a mounting tube 62, an oil guide 63 and a heating element 64. The second shell 61 is installed on the first mounting position 11, and the mounting tube 62 is arranged inside the second shell 61. The space between the second shell 61 and the mounting tube 62 is an oil storage chamber 66, and the interior of the oil storage chamber 66 is provided with an aerosol generating matrix. The aerosol generating matrix can be, for example, smoke oil, liquid medicine, etc. Further, the atomizing device 60 can also include an oil storage member 67, which is arranged inside the oil storage chamber 66. The material of the oil storage member 67 can be a porous material, and the aerosol generating matrix is ​​accommodated in the pores of the oil storage member 67. The material of the oil storage member 67 can be, for example, cotton fiber, porous ceramics, etc.

[0036] The oil guide member 63 is arranged inside the mounting tube 62, and a through hole 621 is provided on the mounting tube 62. The through hole 621 is used to allow the aerosol generating matrix in the oil storage chamber 66 to be introduced into the oil guide member 63. The oil guide member 63 can be made of a porous material, such as cotton fiber, porous ceramic, etc. An atomizing airway 631 is arranged inside the oil guide member 63, and a heating member 64 is arranged on the side wall of the atomizing airway 631. A wiring portion 65 is arranged at one end of the heating member, and the wiring portion 65 is used to be electrically connected to the battery.

[0037] The housing assembly 10 is also provided with a first airflow channel 12, which is used to communicate with the atomizing airway 631 of the atomizing device 60. In addition, the aerosol generating device may further include a suction piece 70, which is mounted at one end of the housing assembly 10 away from the first airflow channel 12. The suction piece 70 may be detachably connected to the housing assembly 10, or may be integrally formed with the housing assembly 10. A second airflow channel 71 is provided inside the suction piece 70, which is used to communicate with one end of the atomizing airway 631 away from the first airflow channel 12. When the user inhales, the gas enters the first airflow channel 12 from the air inlet of the first airflow channel 12, flows from the first airflow channel 12 to the atomizing airway 631, and carries the aerosol atomized in the atomizing airway 631 to flow to the second airflow channel 71, and finally flows out from the second airflow channel 71 of the suction piece 70.

[0038] The aerosol generating device may not include the atomizing device 60, and only the first mounting position 11 is provided inside the housing assembly 10. The atomizing device 60, as a consumable, may be detachably assembled with the housing assembly 10 or the like. Of course, the atomizing device 60 may also include the atomizing device 60, and the atomizing device 60 may be detachably assembled with the housing assembly 10 or the like, or may be integrally arranged with the housing assembly 10.

[0039] In one embodiment, if Figure 3 As shown, the first light guide wall 31 of the light guide bracket 30 has a first side portion 311 and a second side portion 312 that are arranged opposite to each other, and the first side portion 311 and the second side portion 312 can be arranged opposite to each other in the horizontal direction. At least part of the second light guide wall 32 is bent to form a curved surface structure, and the curved surface structure extends from the first side portion 311 of the first light guide wall 31 to the second side portion 312 of the first light guide wall 31, and the first light guide wall 31 and the second light guide wall 32 are enclosed to form a receiving cavity 33. The first light guide wall 31 and the second light guide wall 32 of the light guide bracket 30 can be integrally formed. By setting at least part of the second light guide wall 32 as a curved surface structure, the curved surface structure is less likely to have uneven distribution of light effects compared to some structures with corners. The structure with corners is prone to uneven light distribution at corners and other positions.

[0040] In one embodiment, if Figure 3As shown, the control circuit board 50 is parallel to the height direction of the aerosol generating device, that is, the control circuit board 50 extends in the vertical direction. Generally, the height direction of the aerosol generating device is defined as the air outlet direction from the atomizing airway 631 of the aerosol generating device to the suction member 70. A plurality of light-emitting members 20 are distributed on the control circuit board 50, and the plurality of light-emitting members 20 are arranged in the height direction of the aerosol generating device. By arranging a plurality of light-emitting members 20 on the vertically arranged control circuit board 50, the aerosol generating device can have a large-area light-guiding effect, and the brightness at all locations in the height direction is relatively uniform. Compared with some solutions in which the light-emitting members 20 are only arranged at the bottom of the aerosol generating device for lighting, there will be no uneven brightness effect of bright bottom and dark middle and top.

[0041] In other embodiments, the light emitting elements 20 at any height position may also form a light emitting element group, and several light emitting element groups are arranged on the control circuit board 50 along the height direction of the aerosol generating device. Figure 3 In the embodiment, the control circuit board 50 has three rows of light-emitting element groups, which are respectively distributed in the upper, middle and lower parts of the control circuit board 50, and each row of light-emitting element groups has two light-emitting components 20, and one light-emitting component 20 is arranged near the first side portion 311 of the light guide bracket 30, and the other light-emitting component 20 is arranged near the second side portion 312 of the light guide bracket 30.

[0042] In one embodiment, the outer side surface of the first light guide wall 31 is a plane and is parallel to the control circuit board 50. At least two convex ribs 314 for limiting the control circuit board 50 are provided at the bottom of the first light guide wall 31, and the control circuit board 50 abuts against at least two convex ribs 314. Figure 4 In the embodiment, three convex ribs 314 are provided on the first light guide wall 31, and the two side surfaces of the control circuit board 50 and the side of the control circuit board 50 facing the first light guide wall 31 are respectively abutted against the three convex ribs 314. The three convex ribs 314 can play a role in fixing and positioning the control circuit board 50, so that the light-emitting component 20 on the control circuit board 50 can be accurately irradiated onto the outer surface of the first light guide wall 31.

[0043] Furthermore, the bottom surface of the control circuit board 50 can be in contact with the bottom shell 15 , that is, at least two ribs 314 cooperate with the bottom shell 15 to form a second mounting position 313 , and the control circuit board can be set in the second mounting position 313 to achieve fixation and positioning.

[0044] In addition, if Figure 2 and Figure 3As shown, a groove 52 may be further provided on the side of the control circuit board 50 close to the installation of the atomization device 60, and a protrusion 611 may be provided on the second shell 61, and the protrusion 611 is engaged with the groove 52 of the control circuit board 50 to further fix the control circuit board 50. In other embodiments, a protrusion may be provided on the control circuit board 50, and a groove matching the protrusion may be provided on the second shell 61, or the control circuit board 50 may also have other fixing methods, which are not given as examples here.

[0045] In one embodiment, if Figure 4 and Figure 5 As shown, the first light guide wall 31 and the second light guide wall 32 enclose a receiving cavity 33, and the aerosol generating device also includes a microphone circuit board 80, at least a portion of which is arranged inside the receiving cavity 33, and a first mounting position 11 is arranged on one side of the microphone circuit board 80, and the microphone circuit board 80 is used to be electrically connected to the atomization device 60.

[0046] Specifically, the control circuit board 50 is parallel to the height direction of the aerosol generating device, one end of the microphone circuit board 80 is fixed on the control circuit board 50, and there is an angle between the microphone circuit board 80 and the control circuit board 50, which can be about 90 degrees, for example, 85-95 degrees. Since the control circuit board 50 is generally arranged vertically, the microphone circuit board 80 is arranged horizontally. The horizontally arranged microphone circuit board 80 separates the accommodating cavity 33 into an upper cavity and a lower cavity. The atomizing device 60 is usually arranged in the upper cavity, and the lower cavity can be provided with a first airflow channel 12, a battery, etc. By setting the microphone circuit board 80, it is beneficial to divide the internal space of the aerosol generating device into modules, which is convenient for arranging various components.

[0047] The microphone circuit board 80 may be provided with an electrode 81 and a microphone 82. The electrode 81 is electrically connected to the wiring portion 65 of the atomizing device 60, and the microphone 82 is provided on a side of the microphone circuit board 80 close to the first airflow channel 12. The microphone 82 is mainly used in the atomizing device 60 to receive the user's inhalation signal, thereby controlling the start and stop of the aerosol generating device.

[0048] In one embodiment, if Figure 4 and Figure 5 As shown, Figure 4The box on the first light guide wall 31 in the figure indicates the position where the light emitting element 20 irradiates on the first light guide wall 31. The control circuit board 50 is arranged outside the accommodating cavity 33, and the first light guide wall 31 has a through installation opening 315. The microphone circuit board 80 includes a placement portion 83 and a docking portion 84 connected to each other. The placement portion 83 is arranged inside the accommodating cavity 33. At least part of the docking portion 84 extends to the outside of the accommodating cavity 33 through the installation opening 315 and is connected to the control circuit board 50. An avoidance position 90 is formed between the placement portion 83 and the control circuit board 50, and the first light guide wall 31 of the light guide bracket 30 is clamped at the avoidance position 90. By clamping the light guide bracket 30 at the avoidance position 90, the avoidance position 90 limits the movement of the light guide bracket 30 in the horizontal direction, and the light guide bracket 30, the control circuit board 50 and the microphone circuit board 80 can be effectively fixed together.

[0049] Furthermore, the first light guide wall 31 has a through mounting opening 315, and the light guide bracket 30 has a clamping portion 316 adjacent to the mounting opening 315, and the clamping portion 316 is clamped with the avoidance position 90. In one embodiment, the second light guide wall 32 is a curved surface structure, there are two avoidance positions 90, and the clamping portion 316 is two opposite clamping portions 316 adjacent to the mounting opening 315, and the two clamping portions 316 are clamped with the two avoidance positions 90 respectively.

[0050] like Figure 5 As shown, in one embodiment, a button 53 may be provided on the control circuit board 50. Since the control circuit board 50 is vertically provided, the button 53 may be easily exposed from the side wall of the first shell 14 of the housing assembly 10 for user touch control. By arranging the control circuit board 50 and the microphone circuit board 80 in different directions, it is convenient to arrange the parts on the circuit board in a reasonable manner according to their required arrangement positions.

[0051] For example, in one embodiment, a sliding groove 54 is provided on the control circuit board 50, and the aerosol generating device further includes a button 53 and a toggle switch 55, the button 53 is slidably connected to the sliding groove 54, and the sliding direction of the button 53 can be up and down sliding, that is, sliding along the height direction of the aerosol generating device. The toggle switch 55 is provided on the control circuit board 50 and is provided on the sliding path of the button 53, so that the toggle switch 55 can be toggled when the button 53 slides. In one embodiment, a first protrusion 56 and a second protrusion 57 are provided on the button 53 at intervals, and the first protrusion 56 and the second protrusion 57 are both provided toward the toggle switch 55, and the toggle switch 55 is sandwiched between the first protrusion 56 and the second protrusion 57. When the button 53 slides up and down, the first protrusion 56 and the second protrusion 57 can drive the toggle switch 55 to switch gears up and down.

[0052] When the toggle switch 55 is toggled, the light display mode of the light-emitting element 20 can be switched. Generally, the control circuit board 50 is set as a control unit (Microcontroller Unit, referred to as MCU) to control the light display mode of the light-emitting element 20. For example, in an aerosol generating device, the heating wire adopts a single-row mesh heating wire with a resistance in the range of 1.0 ohms to 1.2 ohms. When the aerosol generating device is in the burst mode (heating power is 15W-18W), the light of the light-emitting element 20 is displayed in blue, and when the aerosol generating device is in the normal mode (heating power is 8W-11W), the light of the light-emitting element 20 is displayed in green. When the toggle switch 55 is toggled, the burst mode and the normal mode can be switched, thereby switching the color of the light-emitting element 20 to meet the different suction needs of consumers.
