In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0036] See also Figure 1-6As shown, the present application provides an aerosol generating device 100, which has a suction end 10. When inhaling, the suction end 10 is directed toward the user and close to the user. The aerosol generating device 100 includes a shell 20, a heating module 30, a pressure relief protective cover 40 and a power module 50. The heating module 30 is connected to one side of the shell 20 and is close to the suction end 10, and the heating module 30 is configured to heat the aerosol matrix to generate an aerosol. The pressure relief protective cover 40 is arranged in the shell 20 and is used to accommodate the power module 50. The power module 50 is configured to supply power to the heating module 30 so that the heating module 30 heats the aerosol matrix when powered on.

[0037] Furthermore, the housing 20 is constructed to have a receiving space 23 and a pressure relief hole 24. The pressure relief hole 24 communicates with the receiving space 23 and is located away from the suction port 10. The pressure relief protective cover 40 is disposed within the receiving space 23 and is constructed to have a pressure relief port 42 and a receiving compartment 41. The pressure relief port 42 communicates with the receiving compartment 41 and the pressure relief hole 24. The power module 50 is disposed within the receiving compartment 41.

[0038] In this embodiment, under the protection of the pressure relief protection cover 40, when the power module 50 accommodated in the accommodation space 23 encounters an abnormality and explodes, the ejecta and the explosion impact force generated thereby will move toward the pressure relief hole 24 through the pressure relief port 42, thereby preventing the ejecta and the explosion impact force from being ejected toward the user near the suction end 10 and threatening the user's safety.

[0039] Furthermore, the pressure relief protective cover 40 is made of a pressure-resistant, high-temperature-resistant, and flame-retardant metal material. This allows the pressure relief protective cover 40 to effectively limit bulging of the power module 50 during periods of abnormality and explosion, withstand the impact of ejected matter after the explosion, and prevent the high temperature and flames generated during the process from spreading toward the suction end 10.

[0040] Furthermore, the pressure relief protective cover 40 can be made of materials such as stainless steel, zinc alloy, and iron.

[0041] Further, see Figure 5 and Figure 7 As shown, the pressure relief protection cover 40 includes a side wall 43 and a peripheral wall 44. The peripheral wall 44 extends along the periphery of the side wall 43 toward the pressure relief hole 24 to form the pressure relief port 42, and the peripheral wall 44 and the side wall 43 form the receiving chamber 41.

[0042] When the power module 50 is installed, the power module 50 enters the receiving compartment 41 from the pressure relief port 42. The end of the power module 50 close to the pressure relief port 42 may extend out of the pressure relief port 42 or not.

[0043] Furthermore, the peripheral wall 44 and the side wall 43 are integrally formed, so that the connection between the peripheral wall 44 and the side wall 43 is stronger and more stable.

[0044] For further information, please refer to Figure 2-3 As shown, the pressure relief port 42 is at least partially opposite to the pressure relief hole 24. Therefore, when the power module 50 malfunctions and explodes, the ejected matter and the explosive force generated thereby will move directly from the pressure relief port 42 toward the pressure relief hole 24, thereby further reducing the impact of the ejected matter and the explosive force generated by the explosion of the power module 50 on the user.

[0045] Preferably, the pressure relief hole 24 is directly opposite to the pressure relief port 42 , and the pressure relief hole 24 is arranged opposite to the suction end 10 , so that the jet and impact force ejected through the pressure relief port 42 are directly released in a direction away from the user.

[0046] For further information, please refer to Figure 4-6 As shown, a groove 441 is formed on the inner side of the peripheral wall 44, which communicates with the storage compartment 41. The groove 441 is spaced from the power module 50 contained within the storage compartment 41. If the power module 50 malfunctions and bulges, the groove 441 can provide a buffer for the bulge, thereby reducing or delaying the explosion of the power module 50.

[0047] Furthermore, a plurality of grooves 441 are formed at intervals on the inner side of the peripheral wall 44 , and the plurality of grooves 441 are arranged at intervals.

[0048] Furthermore, in one embodiment, the positive pole and the negative pole of the power module 50 are arranged opposite to each other, and one of the positive pole and the negative pole is close to the side wall 43 , and the other of the positive pole and the negative pole is close to the pressure relief port 42 .

[0049] Furthermore, at least one of the grooves 441 extends from the side wall 43 to the pressure relief port 42 , so that the lead wire drawn from the positive electrode or the negative electrode near the side wall 43 extends from the groove 441 to the pressure relief port 42 .

[0050] Further, see Figure 2-3 and Figure 7-8As shown, the housing 20 includes an outer shell 21 and a bracket 22. The bracket 22 is at least partially disposed in the outer shell 21 and is configured to form the receiving space 23 with the outer shell 21.

[0051] Specifically, the bracket 22 includes a first portion 221 and a second portion 222 connected to each other. The first portion 221 is disposed within the housing 20 and forms the receiving space 23 with the housing 20. The second portion 222 extends out of the housing 20 and is connected to the heating module 30.

[0052] Furthermore, the first portion 221 includes a first limiting plate portion 2211, a second limiting plate portion 2212, and a connecting plate portion 2213 that are arranged opposite to each other. The connecting plate portion 2213 extends along the suction end 10 toward the pressure relief hole 24. The first limiting plate portion 2211 is connected to an end of the connecting plate portion 2213 that is closer to the suction end 10, and the second limiting plate portion 2212 is connected to an end of the connecting plate portion 2213 that is farther from the suction end 10.

[0053] Among them, the first limiting plate portion 2211, the second limiting plate portion 2212 and the connecting plate portion 2213 are jointly constructed to form a receiving groove 2214, the pressure relief protection cover 40 is at least partially located in the receiving groove 2214, and the side wall 43 abuts against the first limiting plate portion 2211, the peripheral wall 44 or the end of the power module 50 away from the side wall 43 abuts against the second limiting plate portion 2212, and the peripheral wall 44 is at least partially in surface contact with the connecting plate portion 2213, so that the pressure relief protection cover 40 and the power module 50 are at least partially limited in the receiving groove 2214.

[0054] Furthermore, the connecting plate portion 2213 is an arc-shaped structure, and together with the first limiting plate portion 2211 and the second limiting plate portion 2212, forms an opening communicating with the receiving groove 2214. The pressure relief protection cover 40 containing the power module 50 is installed into the receiving groove 2214 through the opening.

[0055] For further information, please refer to Figure 4-6 As shown, the outer side of the pressure relief protection cover 40 is structured to form a limiting protrusion 442 , and the limiting protrusion 442 abuts against the opening between the inner wall of the shell 21 and the connecting plate portion 2213 .

[0056] Furthermore, the side of the limiting protrusion 442 facing the receiving groove 2214 respectively abuts against the position of the opening of the connecting plate portion 2213, and the outer side surface of the limiting protrusion 442 abuts against the inner wall 43 of the outer shell 21, so that the pressure relief protection cover 40 is limited to the limiting space.

[0057] In some embodiments, the limiting protrusion 442 corresponds to the position of the groove 441 , so that the integrally formed pressure relief protective cover 40 can form the groove 441 while partially protruding the peripheral wall 44 outward to form the limiting protrusion 442 .

[0058] Furthermore, the bracket 22 further includes a third portion 223 and a fourth portion 224. The third portion 223 is connected to an end of the first portion 221 away from the second portion 222, and the fourth portion 224 is connected between the first portion 221 and the second portion 222.

[0059] For further information, please refer to Figure 2-3 As shown, the aerosol generating device 100 further includes a control module. The control module includes a first control circuit board 61, a second control circuit board 62, and a third control circuit board 63. The first control circuit board 61 is electrically connected to the second control circuit board 62, the third control circuit board 63, and the heating module 30, respectively. The first control circuit board 61 and the third control circuit board 63 are spaced apart from each other along the direction from the first portion 221 to the second portion 222, thereby effectively reducing the overall length of the bracket 22, and thereby effectively reducing the overall length of the aerosol generating device 100.

[0060] Furthermore, the control module further includes a charging interface 64. The charging interface 64 and the second control circuit board 62 are respectively provided in the third portion 223, and the charging interface 64 and the power module 50 are respectively electrically connected to the second control circuit board 62.

[0061] Furthermore, the control module further includes a control button 65 and a control switch 66, wherein the control switch 66 is provided on the third control circuit board 63 and is electrically connected to the third control circuit board 63. The control button 65 is pressably provided on the housing 21 and faces the control switch 66.

[0062] Furthermore, the housing 20 includes a dust cover 70. The dust cover 70 covers the pressure relief hole 24 and is capable of opening the pressure relief hole 24 when the pressure in the receiving space 23 reaches a preset pressure. The provision of the dust cover 70 effectively prevents external liquids and foreign matter from entering the receiving space 23, thereby protecting the receiving space 23.

[0063] Furthermore, a relief hole 71 is formed on the dust cover 70 , and the relief hole 71 is connected to the charging port 64 .

[0064] Furthermore, in one embodiment, the aerosol generating device 100 is used to heat and bake the aerosol generating article inserted into the heating module 30 to generate aerosol.

[0065] In another embodiment, the aerosol generating device 100 is used to heat and atomize a liquid aerosol matrix to generate an aerosol.

[0066] Furthermore, in one embodiment, the heating module 30 and the housing 20 are arranged side by side, so that the heating module 30 is located on one side of the housing 20 .
