[0019] Please see Figure 1-4 , Figure 1This is a schematic structural diagram of the replaceable core structure provided in an embodiment of the present invention. Figure 1 As shown, this embodiment of the invention provides a replaceable cartridge structure 1, including a nozzle assembly 10 and a replaceable cartridge assembly 20; the nozzle assembly 10 includes a nozzle 11 and an upper silicone 12, the upper silicone 12 being adapted to and connected to the nozzle 11, and the upper silicone 12 having a hollow channel; the nozzle 11 includes a nozzle portion 111 and a replaceable cartridge connecting portion 112, the bottom end of the replaceable cartridge connecting portion 112 being accommodated in the hollow channel; the replaceable cartridge assembly 20 is detachably connected to the replaceable cartridge connecting portion 112.

[0020] In this embodiment, when any type of aerosol generating device is specifically configured internally, the replaceable core structure 1 can be installed inside the aerosol generating device body after the aerosol generating device body is configured. This avoids the aerosol generating device being directly discarded when the components of the replaceable core structure 1 are damaged and cannot work, or when the aerosol matrix is ​​used up. The aerosol generating device can be reused, which effectively saves resources. Moreover, when installing or disassembling the replaceable core structure, it is only necessary to rotate it in any direction to install or disassemble it and perform subsequent operations, which effectively improves the efficiency of replacing the replaceable core structure 1.

[0021] When a user uses an aerosol generator equipped with the replaceable core structure 1, if the replaceable core structure 1 component of the aerosol generator is damaged and cannot work, the replaceable core structure 1 can be removed from the aerosol generator, and then the replaceable core assembly 20 can be removed from the replaceable core connection part 112 of the nozzle assembly 10 to replace the damaged replaceable core assembly 20; or after the aerosol matrix in the aerosol generator is used up, the replaceable core structure 1 can be removed from the aerosol generator and oil filling can be performed directly.

[0022] When an aerosol generating device equipped with the replaceable core structure 1 is inoperable or when the aerosol matrix in the aerosol generating device is used up, the replaceable core structure 1 can be removed from the aerosol generating device and the damaged replaceable core structure 1 component can be replaced or an oiling operation can be performed. This eliminates the need to discard the aerosol generating device, effectively saving resources and reducing usage costs.

[0023] The upper silicone 12 serves to seal and prevent leakage of the aerosol matrix in the core oil storage cotton 34. The replaceable core assembly 20 and the replaceable core connecting part 112 are detachably connected. Here, detachable connection means that the replaceable core assembly 20 and the replaceable core connecting part 112 can be plugged in and unplugged, that is, the replaceable core assembly 20 and the replaceable core connecting part 112 can be installed and removed.

[0024] In one embodiment, such as Figure 1 and Figure 2 As shown, the replaceable core assembly 20 includes an air guide tube 21, an inner cotton padding 22, and a heating wire 23, with the heating wire 23 disposed inside the inner cotton padding 22; the bottom end of the replaceable core connecting part 112 is provided with a groove; the top end of the air guide tube 21 is provided with a snap-fit ​​211 that matches the groove of the replaceable core connecting part 112.

[0025] In this embodiment, the replaceable core assembly 20 includes an air guide tube 21, an inner cotton 22, a heating wire 23, a negative electrode shell 24, a positive electrode, and an air guide component 25. The inner cotton 22 is a hollow body with protruding portions. The heating wire 23 has a mesh-like hollow structure with a round rod on each side of its bottom end. The negative electrode shell 24 has a round hole that matches the round rod at the lower end of the heating wire 23 for fixing the heating wire 23. The heating wire 23 is disposed inside the inner cotton 22, and the round rod of the heating wire 23 is disposed inside the round hole of the negative electrode shell 24. The negative electrode shell 24 is made of metal, preferably, it is made of metal, i.e., gold, silver, copper, iron, or tin. The air guide component in the positive electrode and the air guide component 25 is made of metal, preferably, it is made of metal, i.e., gold, silver, copper, iron, or tin. The negative electrode shell 24 is hollow, and the positive electrode and the air guide 25 are located inside the negative electrode shell 24. The negative electrode shell 24, the positive electrode, and the air guide 25 are all located below the inner cotton 22 and the heating wire 23. The groove at the bottom of the replaceable core connector 112 is discontinuous, and the groove is divided into M parts, which are adapted to the bayonet 211 at the top of the air guide tube 21. Correspondingly, there are also M bayonet 211s. Here, M can be a positive integer greater than or equal to 2. The value of M is set according to actual needs and is not specifically limited here.

[0026] In one embodiment, such as Figure 1 As shown, the air guide tube 21 is a hollow pipe, and the inner cotton 22 and the heating wire 23 are both fixed inside the hollow pipe of the air guide tube 21.

[0027] In this embodiment, the air guide tube 21 is made of metal, such as gold, silver, copper, iron, tin, or stainless steel. Preferably, the air guide tube 21 is made of stainless steel. The negative electrode shell 24, the positive electrode, and the air guide component 25 are all fixed inside the hollow pipe of the air guide tube 21. Here, the inner cotton 22, the heating wire 23, the negative electrode shell 24, the positive electrode, and the air guide component 25 are all fixed inside the hollow pipe of the air guide tube 21. This allows for the independent installation of the replaceable core assembly 20. When the replaceable core assembly 20 is damaged and cannot work, the entire replaceable core assembly 20 can be directly replaced, and other normal components can be reused repeatedly. This enables the aerosol generating device to be recycled, effectively saving resources and reducing operating costs.

[0028] The design principle of the replaceable core structure 1 is to utilize the rigid metallic properties of the air guide tube 21 and the soft properties of the inner cotton 22 and the core oil storage cotton 34 to achieve convenient assembly. The replaceable core structure 1 separates the replaceable core assembly 20, allowing the user to directly place the replaceable core assembly 20 onto the replaceable core connection part of the nozzle assembly to replace the core.

[0029] In one embodiment, such as Figure 1-3 As shown, the bottom end of the air duct 21 is provided with an opening 212, and the inner cotton 22 and the heating wire 23 are disposed at the opening 212.

[0030] In this embodiment, the bottom end of the air guide tube 21 is provided with an opening 212. The function of the opening 212 is: firstly, to facilitate the protruding part of the inner cotton 22 to be inserted into the air guide tube 21 for fixation; secondly, to allow the inner cotton 22 to better absorb the aerosol matrix in the core oil storage cotton 34 for subsequent aerosol generation operations.

[0031] In one embodiment, such as Figure 1 As shown, the top end of the air guide tube 21 is connected to the bottom end of the suction nozzle 11.

[0032] In this embodiment, the top end of the air guide tube 21 is connected to the bottom end of the suction nozzle 11. The air guide tube 21 is a hollow pipe, and the replaceable core connection portion 112 of the suction nozzle 11 has a hollow section. When the aerosol generating device equipped with the replaceable core structure 1 is working, the heating wire 23 atomizes the aerosol matrix in the inner cotton 22 to generate aerosol. The aerosol is then delivered to the user through the hollow section connecting the air guide tube 21 and the replaceable core connection portion 112.

[0033] In one embodiment, such as Figure 1As shown, the bottom end of the suction nozzle 111 is provided with a slot; the top end of the replaceable core connecting part 112 is connected to the suction nozzle 111, and the replaceable core connecting part 112 is located inside the suction nozzle 111.

[0034] In this embodiment, a slot is provided at the bottom of the nozzle portion 111 for better connection with the aerosol generating device. The top of the replaceable core connector 112 is integrally connected to the nozzle portion 111; the nozzle portion 111 is funnel-shaped, and the upper silicone 12 is placed inside. The upper silicone 12 has a hollow channel, and the replaceable core connector 112 is located inside the hollow channel of the upper silicone 12.

[0035] In one embodiment, such as Figure 1 As shown, the suction nozzle assembly 10 also includes a suction nozzle silicone plug 13 for covering the suction nozzle 11.

[0036] In this embodiment, the silicone plug 13 of the suction nozzle is T-shaped and has a protrusion on it, which is used to cover the suction nozzle 11 and also to increase the resistance with the suction nozzle assembly 10 to prevent it from falling off; the silicone plug 13 of the suction nozzle is placed inside the replaceable core connecting part 112 of the suction nozzle assembly 10.

[0037] Please see the appendix Figure 3 and 4 , Figure 3 A schematic structural diagram illustrating the application of the replaceable core structure provided in an embodiment of the present invention to an aerosol generating device; Figure 4 This is a schematic structural diagram of the outer casing of the aerosol generating device provided in an embodiment of the present invention. Figure 3 As shown, the present invention proposes an aerosol generating device 3, including the replaceable core structure 1 as described above, a main unit assembly 30 connected to the replaceable core assembly 20, and a microphone assembly 40 and a circuit board assembly 50 disposed at the bottom of the aerosol generating device 3; the main unit assembly 30 includes a housing 31 and a core delivery channel 32; the microphone assembly 40 includes a microphone silicone 41 and a microphone 42.

[0038] The microphone 42 is essentially an airflow sensor. Its working principle is to sense changes in airflow in the airway, that is, whether there is airflow passing through the airway. For example, if the airway is open and the user's inhalation action causes the microphone to sense that there is airflow passing through the airway, it will send a sensing signal to the control module of the control circuit in the aerosol generating device, so that the atomizer in the aerosol generating device will start working and thus generate aerosol.

[0039] In this embodiment, the main unit 30 includes a housing 31 and a core dispensing channel 32, and further includes an oil cup 33, a core oil storage cotton 34, a base silicone 35, a spring needle positive electrode 36, a spring needle negative electrode 37, and a soft pad 38. Preferably, the oil cup 33 is made of PCTG material. PCTG (Poly(1,4-Cyclohexylene Dimethylene Terephthalate Glycol)) is a highly transparent copolyester plastic raw material, i.e., a transparent plastic. Preferably, the soft pad 38 is made of EVA (Ethylene Vinyl Acetate Copolymer). EVA is an ethylene-vinyl acetate copolymer, and its chemical properties are those of a general-purpose polymer.

[0040] In one embodiment, such as Figure 1 and Figure 3 As shown, the replaceable core assembly 20 is disposed inside the core delivery channel 32.

[0041] In this embodiment, the core oil-storing cotton 34 fills the inside of the oil cup 33; the core oil-storing cotton 34 is provided with a core delivery channel 32, the diameter of which is larger than the outer diameter of the air guide tube 21, and the air guide tube 21 of the replaceable core assembly 20 is positioned within the core delivery channel 32. When the replaceable core assembly 20 of the replaceable core structure 1 is inserted into the core delivery channel 32 of the aerosol generating device 3, and current is conducted through the positive electrode 36 and the negative electrode 37 of the spring needle, the aerosol generating device 3 can then be used normally.

[0042] In one embodiment, such as Figure 1 and Figure 4 As shown, a slot is provided at the bottom of the nozzle part 111; a buckle 311 is provided inside the outer shell 31 for detachable integral connection with the slot of the nozzle part 111.

[0043] In this embodiment, the housing 31 is provided with a buckle 311 that matches the slot of the nozzle part 111. When installing and connecting, it is only necessary to offset the positions of the replaceable core structure 1 and the buckle 311 of the housing 31 and rotate it in any direction to connect the replaceable core structure 1 and the aerosol generating device 3. The operation is simple and effectively improves the efficiency of replacing the replaceable core structure 1.

[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
