[0025] Please refer to Figures 1-4 The present application provides an aerosol generating device, which comprises a housing assembly 10, a heating element 20 and a lighter generator 30.
[0026] The housing assembly 10 comprises a shell 11 and a support 12. The support 12 is arranged in the shell 11 to divide the internal space of the shell 11 into a first mounting cavity 111 and a second mounting cavity 112. Among them, the first mounting cavity 111 and the second mounting cavity 112 are not two completely sealed cavities, and the support 12 only modularly divides the internal space of the shell 11, so that the housing assembly 10 is divided into different functional areas, which is beneficial to the reasonable arrangement of various parts in the housing assembly 10.
[0027] A mounting cavity 1111 is arranged in the first mounting cavity 1111, and the mounting cavity 1111 has a first opening 1112 communicating with the outside of the shell 11 at one end of the axial direction of the mounting cavity 1111. The first opening 1112 can be used for inserting and withdrawing the aerosol substrate 40 into the mounting cavity 1111. Among them, the aerosol substrate 40 is adapted to a heating non-combustion type smoking mode, usually, the aerosol substrate 40 comprises a substrate section, a cooling section and a mouthpiece section, the substrate section is provided with a leafy substrate such as tobacco, and the leafy substrate can generate aerosol when heated; the cooling section is provided with a cooling hole, and cold air can enter the cooling section through the cooling hole and mix with the aerosol to reduce the temperature of the aerosol to avoid burning the mouth; the user can suck the aerosol generated in the heating non-combustion mode through the suction of the mouthpiece section.
[0028] The heating element 20 is arranged in the first mounting cavity 111, and the heating element 20 is used to heat the aerosol substrate 40 in the assembly cavity 1111, so that the aerosol substrate 40 generates aerosol by heating without combustion. The heating element 20 may, for example, adopt a resistance heating mode such as a heating tube, a heating needle, etc., and in other embodiments, the heating element 20 may also adopt electromagnetic induction heating, infrared heating, microwave heating, etc. to heat the aerosol substrate 40.
[0029] At least part of the lighter generator 30 is arranged in the second mounting cavity 112, and the second mounting cavity 112 has a second opening 1121 communicating with the outside of the shell 11. At least part of the lighter generator 30 is arranged at the second opening 1121, so that the lighter generator 30 can ignite a combustible object. The lighter generator 30 can extend out of the second opening 1121, or the lighter generator 30 can be located in the second opening 1121, as long as the user can use the lighter generator 30 to ignite a combustible object.
[0030] The aerosol generating device of the present application is provided with an assembly cavity 1111, in which a heating without combustion type aerosol substrate 40 can be inserted, and a heating element 20 is used to heat the aerosol substrate 40, so that the aerosol substrate 40 generates aerosol by heating without combustion for the user to use. In addition, the aerosol generating device is also provided with a lighter generator 30, which can be exposed from the aerosol generating device through the second opening 1121, so that the lighter generator 30 can ignite a conventional cigarette. Therefore, the user only needs to carry the aerosol generating device to meet the needs of smoking aerosol generated by heating without combustion and smoking a combustible cigarette. The user does not need to carry both the aerosol generating device and a lighter, thereby reducing the equipment the user needs to carry, and improving the convenience for the user.
[0031] In an embodiment, the lighter generator 30 is an electric arc generator. The electric arc generator generally includes two electrodes, and when the electric arc generator is powered on, an electric arc can be generated at a gap between the two electrodes, which requires a high voltage between the two electrodes. Therefore, the electric arc generator is generally electrically connected with an electric arc generating circuit, which can convert the electric energy of the battery 60 into a high voltage current through a high frequency oscillation circuit to make the electric arc generator generate the electric arc. Compared with the liquid gas lighter, the electric arc generator is more suitable for the aerosol generating device. The aerosol generating device generally includes the battery 60, which can supply power to the heating element 20, and the controller, which can control the heating of the heating element 20. The electric arc generator also needs the battery 60 to provide a high voltage and needs the controller to control the start. Therefore, the electric arc generator is more suitable to be assembled in the aerosol generating device, and only needs to additionally add the electric arc generator and the connecting line 70 in the aerosol generating device, without the need to additionally add more parts, so as to prevent the aerosol generating device from being too large in size due to the occupation of too much space in the aerosol generating device by the lighter, and to prevent the user from carrying the aerosol generating device inconveniently.
[0032] In addition, the electric arc lighter is powered by the battery 60 and does not produce harmful gases or burning substances, and is more environmentally friendly than the liquid gas lighter. The electric arc lighter does not rely on a flame and ignites the target through an electric arc, so it can be used in various bad weather, which can broaden the application scenarios of the lighter. The electric arc lighter is generally adapted to a rechargeable battery, so it can be used multiple times after charging, and is more economical than disposable lighters.

For example, in the embodiment of Figure 3 The first opening 1112 and the second opening 1121 are both located on the top side of the housing assembly 10 and are both formed on the top wall of the housing assembly 10, and the first opening 1112 and the second opening 1121 both face upward. By arranging the first opening 1112 and the second opening 1121 on the same side of the housing assembly 10, the user can complete the use of the two types of suction methods of the heating and non-combustion method and the lighter method on the same side of the housing assembly 10, which can reduce the operation complexity of the user using the aerosol generating device and improve the user experience. In other embodiments, the first opening 1112 and the second opening 1121 can face different sides of the housing assembly 10.

In this way, the power supply can be modularized, and when the power supply needs to be replaced, the parts in the first mounting cavity 111 and the second mounting cavity 112 do not need to be disassembled, only the power supply in the third mounting cavity 113 needs to be disassembled and replaced. The circuit board 50 can be assembled in the first mounting cavity 111 or the third mounting cavity 113, and preferably, the circuit board 50 is assembled in the third mounting cavity 113, so that the circuit board 50, the power supply and the lighter generator 30 are all separated from the components of the heating non-combustion module by the support 12, preventing liquid leakage from the heating non-combustion module to the electronic components. In other embodiments, the second mounting cavity 112 and the third mounting cavity 113 can be combined into one cavity.

In other embodiments, the arrangement in the aerosol-generating device is not limited to the above manner, and can also be other reasonable arrangement manners.
[0037] In an embodiment, as shown,Figure 4 As shown, the aerosol-generating device further comprises a key switch assembly 80, which is electrically connected with the circuit board 50. Specifically, the key switch assembly 80 can comprise a key switch 81 and a pressing piece 82, the key switch 81 is electrically connected with the circuit board 50, and the key switch 81 is arranged towards the side wall of the bracket 12.

One end of the pressing piece 82 abuts against the key switch 81, and the other end of the pressing piece 82 passes through the first through hole 121 and is arranged at the second through hole 114. In this way, the user can press the pressing piece 82 to press the key switch 81 to control the start and stop of the lighter generator 30 and control the start and stop of the heating piece 20.
