[0031] The present application provides an embodiment of an aerosol generating device 100, such as Figure 1 、 Figure 2 、 Figure 3 As shown, the aerosol generating device 100 includes a housing 1, a heating element 2, a circuit board 3, a power supply connector 35, an air flow channel 4, and a liquid guiding element 5. The heating element 2, the circuit board 3, the power supply connector 35, the air flow channel 4, and the liquid guiding element 5 are arranged inside the housing 1. The power supply connector 35 is installed on the circuit board 3 and is at least partially exposed to the outside of the housing 1. The aerosol generating device 100 can be connected to the charging and discharging interface of other electronic devices such as a mobile phone through the power supply connector 35, so that the battery in the mobile phone can be used to provide power to the heating element 2 during inhalation.

[0032] Specifically, the housing 1 includes a first portion 11 having a first end 111 and a second end 112, and a second portion 12 connected to the second end 112. The extension direction of the second portion 12 forms an angle θ with the extension direction of the first portion 11. The first portion 11 contains a liquid storage chamber 113 for storing an aerosol-generating substrate. A liquid-conducting element 5 and a heating element 2 are disposed within the first portion 11. The liquid-conducting element 5 transfers the aerosol-generating substrate within the liquid storage chamber 113 to the heating element 2. The heating element 2 is used to atomize the aerosol-generating substrate to generate an aerosol, which is released into the airflow channel 4. The heating element 2 can be in the form of a heating mesh, a heating sheet, or a heating tube. The liquid-conducting element 5 includes a fiber material or a microporous material with a capillary effect. For example, as an optional example, the heating element 2 is a heating mesh wound into a hollow cylindrical shape, the interior of which forms part of the airflow channel 4, thereby providing air passage and carrying the aerosol. The liquid-conducting element 5 is surrounded by fiber cotton around the periphery of the heating element 2, thereby providing liquid to the heating element 2 from all sides.

[0033] The circuit board 3 is disposed within the second portion 12. A base 17 is provided between the circuit board 3 and the liquid storage chamber 113 of the first portion 11 to support the heating element 2. A second seal 37 is provided between the base 17 and the heating element 2 to prevent liquid from leaking onto the base 17. A first seal 34 is provided between the circuit board 3 and the base 17 to prevent liquid from leaking onto the circuit board 3. A power connector 35 is provided on the circuit board 3 at the end of the second portion 12 away from the first portion 11 for receiving power from an external electronic device, such as a mobile phone.

[0034] The aerosol generating device 100 provided in this embodiment has an included angle θ between the extension direction of the first part 11 and the extension direction of the second part 12 that is less than 180 degrees. This allows the aerosol generating device 100 to be used in conjunction with an electronic device during inhalation, so that the nozzle 13 and the airflow channel 4 are not on the same straight line as the electronic device with a browsing function. This facilitates the user to simultaneously browse the electronic device screen while inhaling the aerosol generating device 100, reduces the switching of operating postures between the inhalation operation and the browsing operation, and conforms to the user's established habit of operating electronic devices.

[0035] In one embodiment of the present application, the angle θ between the first part 11 and the second part 12 can be adjusted by rotation to better suit the user's puffing posture. For example, the user can rotate the first part 11 or the second part 12 to change the angle θ between the two. For example, the angle θ between the first part 11 and the second part 12 can be adjusted between 80 degrees and 120 degrees. In some examples, the connection position between the first part 11 and the second part 12 has a positioning mechanism, so that the angle θ between the first part 11 and the second part 12 can be maintained at multiple gears during the rotation process and can be switched between multiple gears, for example, the multiple gears include 90 degrees, 100 degrees and 120 degrees.

[0036] As an optional example, the first part 11 and the second part 12 may be connected by a hinge, and the user may adjust the angle θ to be comfortable for the user by rotating the first part 11 relative to the second part 12 as needed.

[0037] In one embodiment of the present application, an angle θ between the extension direction of the first portion 11 and the second portion 12 is equal to 90 degrees.

[0038] In one embodiment of the present application, the aerosol-forming matrix includes a liquid of at least one aerosol-forming material, for example, the aerosol-forming material includes glycerol. In some alternative examples, the aerosol-forming matrix may include tobacco extract, betel nut extract or other plant extracts, and may also include synthetic alkaloids, and may also include pharmaceutical ingredients. For example, the aerosol-forming material includes a combination of nicotine salt, glycerol, propylene glycol and a cooling agent or a flavoring agent. It has been found that the aerosol-forming material improves the sensory properties of the aerosol-forming matrix by helping to transfer compounds (such as flavor compounds) from the aerosol-forming material to the consumer. The first end 111 of the first part 11 has a mouthpiece 13 for providing a user with suction, and the mouthpiece 13 is connected to the internal air flow channel 4. The liquid-conducting element 5 conducts the liquid matrix in the liquid storage chamber 113 to the heating element 2, thereby atomizing to generate an aerosol; the aerosol enters the mouthpiece 13 through the air flow channel 4.

[0039] In another embodiment of the present application, the aerosol-generating substrate comprises a solid substrate of tobacco or other plant components. In an optional example, a tobacco product capable of being used in conjunction with an aerosol-generating device is provided, the tobacco product comprising an outer wrapper, a substrate segment located within the outer wrapper, and a mouthpiece segment, the substrate segment comprising shredded tobacco, tobacco flakes, tobacco paste, etc., and the mouthpiece segment being provided for inhalation by the user; a heating chamber is provided within the first portion 11 of the housing 1 for inserting the tobacco product to heat the tobacco material within the substrate segment of the tobacco product to generate an aerosol, and a heating element 2 is disposed within the heating chamber or adjacent to the heating chamber to transfer heat to the heating chamber.

[0040] In one embodiment of the present application, the circuit board 3 includes a first surface 31 facing the first portion 11 and a second surface 32 facing away from the first portion 11. An airflow sensor 33 is disposed on the first surface 31, one side of which is connected to the airflow channel 4. The housing 1 is provided with an air inlet 14, located on the side of the first portion 11 facing away from the power connector 35. The first surface 31 of the circuit board 3 includes a circuit electrically connected to the power connector 35. The airflow sensor 33 can draw power from an electronic device, such as a mobile phone, through this circuit. Furthermore, a pin of the heating element 2 is electrically connected to the airflow sensor 33. When the power connector 35 is connected to the mobile phone, the airflow sensor 33 is powered on and activated. When a user inhales, airflow enters the airflow channel 4 through the airflow sensor 33. In response to this negative pressure, the airflow sensor 33 connects the heating element 2 to the mobile phone power supply, thereby enabling the heating element 2 to generate heat.

[0041] In one embodiment of the present application, a first seal 34 is further provided on the first surface 31 , and the airflow sensor 33 is at least partially accommodated inside the first seal 34 . The first seal 34 is used to seal the gap between the airflow sensor 33 and the first surface 31 .

[0042] In one embodiment of the present application, the power supply connector 35 is a Type-C plug. In another embodiment of the present application, the power supply connector 35 is a Lightning connector adapted for an Apple mobile phone.

[0043] In one embodiment of the present application, a flexible sleeve 16 is provided on the housing 1. The flexible sleeve 16 wraps around the second portion 12 and a portion of the first portion 11, or the flexible sleeve 16 constitutes at least a portion of the second portion 12. The flexible sleeve 16 wraps around the circuit board 3 on the second portion 12, thereby enhancing the sealing performance of the circuit board 3. Furthermore, the flexible sleeve 16 includes a window 15 on the first portion 11, which exposes a partial surface area of ​​the first portion 11, allowing the user to observe the remaining amount of liquid in the liquid storage chamber 113 or to reveal an inlet for injecting liquid into the liquid storage chamber 113. As an example, the flexible sleeve is made of a thermoplastic elastomer or silicone material. Thermoplastic elastomers offer excellent anti-slip properties and a flexible feel, enhancing the device's tactile feel and grip. Furthermore, thermoplastic elastomers are phthalate-free, halogen-free, and free of 38 SVHC substances of very high concern (SVHCs) specified by REACH. They are recyclable and reusable, further enhancing the environmental performance and user safety of the aerosol generating device 100. Furthermore, their low raw material cost and ease of molding further reduce costs.

[0044] In one embodiment of the present application, since the power supply voltage of an electronic device with a Type-C interface is generally about 5V, and the suitable power range of the aerosol generating device 100 provided in the present application is preferably 5W to 10W, the resistance configuration of the heating element 2 is 0.5Ω to 1Ω, which is more able to meet the atomization power requirement.

[0045] In one embodiment of the present application, the circuit board 3 is provided with screw fixing holes 36, and the circuit board 3 is fixed to the first part 11 by screws engaging the screw fixing holes 36. In other embodiments, the circuit board 3 can also be mounted on the second part 12 by screws, snaps, or adhesives.

[0046] It should be noted that the specification and drawings of this application provide preferred embodiments of the present application, but are not limited to the embodiments described in this specification. Furthermore, it is possible for a person skilled in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
