The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] The following is a detailed description of an aerosol generating device 100 provided in an embodiment of the present application through a specific embodiment in conjunction with all the drawings in the specification.

[0044] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment of the utility model, an aerosol generating device 100 is disclosed, including a nozzle assembly 10 and an atomizing body 20, the nozzle assembly 10 is provided with an air suction cavity 102; the atomizing body 20 includes a heating assembly 21, an airflow controller 22, a protrusion 23 and a sealing silicone 24, the atomizing body 20 is provided with an air inlet hole 201, an atomizing cavity 202, an airflow control cavity 203, a connecting hole 204 and an oil storage cavity 205; the nozzle assembly 10 is installed on the atomizing body 20, a first oil storage cavity 30 is formed between the nozzle assembly 10 and the atomizing body 20, the protrusion 23 is located in the first oil storage cavity 30, and the connecting hole 204 runs through the protrusion 23.

[0045] The opening of the oil storage chamber 205 faces the suction nozzle assembly 10, the sealing silicone 24 seals the opening of the oil storage chamber 205, the airflow control chamber 203 is opened in the sealing silicone 24, and the protrusion 23 is connected to the sealing silicone 24; the sealing silicone 24 includes an oil storage plane 242, and a first oil storage chamber 30 is formed between the suction nozzle assembly 10 and the oil storage plane 242, the protrusion 23 is connected to the oil storage plane 242, and is raised relative to the oil storage plane 242, and the protrusion 23 is located in the first oil storage chamber 30.

[0046] The heating component 21 is installed in the atomizing chamber 202, the airflow controller 22 is installed in the airflow control chamber 203, the air inlet hole 201 is connected with the air intake chamber 102 via the atomizing chamber 202 and the first oil storage chamber 30 in sequence, the airflow control chamber 203 is connected with the air intake chamber 102 via the connecting hole 204 and the first oil storage chamber 30 in sequence, the oil storage chamber 205 is connected with the atomizing chamber 202, and the heating component 21 is located at the connecting point between the atomizing chamber 202 and the oil storage chamber 205.

[0047] Through the above structure, when the user inhales the aerosol generating device 100, the gas in the connecting hole 204 flows to the inhalation chamber 102 through the first oil storage chamber 30, so that negative pressure is generated at the airflow controller 22, and the airflow controller 22 controls the heating component 21 to start; the heating component 21 heats the tobacco oil, so that the tobacco oil is atomized to form smoke in the atomization chamber 202; the external airflow enters the atomization chamber 202 through the air inlet hole 201 and mixes with the smoke, and the mixed gas flows to the inhalation chamber 102 through the first oil storage chamber 30 for the user to inhale.

[0048] The airflow control chamber 203 and the atomization chamber 202 are separated from each other, so when the user stops inhaling the aerosol generating device 100, the residual smoke in the atomization chamber 202 is difficult to flow into the airflow control chamber 203, so that the smoke oil is difficult to condense on the surface of the airflow controller 22. In addition, the residual smoke in the air intake chamber 102 and the first oil storage chamber 30 will condense to form condensed oil, and the condensed oil in the air intake chamber 102 will flow into the first oil storage chamber 30; because the protrusion 23 is protruding in the first oil storage chamber 30, the connecting hole 204 passes through the protrusion 23, and the protrusion 23 hinders the condensed oil in the first oil storage chamber 30, so that the condensed oil in the first oil storage chamber 30 will not flow over the protrusion 23 into the connecting hole 204, and finally avoid the airflow controller 22 from being damaged due to the condensed oil adhering to the surface.

[0049] In addition, on the one hand, the sealing silicone 24 is used to seal the oil storage chamber 205, and on the other hand, the sealing silicone 24 and the suction nozzle assembly 10 enclose the first oil storage chamber 30, so that no additional parts are needed to form the first oil storage chamber 30, thereby simplifying the overall structure of the aerosol generating device 100. The sealing silicone 24 has a rough surface and has a strong adsorption effect on the condensed oil, so that the condensed oil is difficult to flow along the cavity wall of the first oil storage chamber 30; because the protrusion 23 is connected to the sealing silicone 24, the condensed oil in the first oil storage chamber 30 is more difficult to flow to the protrusion 23.

[0050] Specifically, in the present embodiment, the suction nozzle assembly 10 is snapped onto the atomizing body 20, the suction chamber 102 is located on one side of the first oil storage chamber 30, the oil storage chamber 205, the atomizing chamber 202 and the airflow control chamber 203 are all located on the other opposite side of the first oil storage chamber 30, and the atomizing chamber 202 and the airflow control chamber 203 are located on the same side of the first oil storage chamber 30, so that the protrusion 23 can better block the smoke in the first oil storage chamber 30.

[0051] The raised portion 23 has a structure similar to a cylinder, and one end of the raised portion 23 away from the airflow control chamber 203 is truncated, the connecting hole 204 is a circular through hole, and the raised portion 23 is coaxially arranged with the connecting hole 204. The airflow controller 22 is a microphone, and the airflow controller 22 has a structure similar to a cylinder, and the connecting hole 204 is directly opposite to the airflow controller 22.

[0052] In other embodiments, the nozzle assembly 10 can also be connected to the atomizer body 20 by other means, such as adhesion; the airflow control chamber 203 can also be located on the same side of the first oil storage chamber 30 as the suction chamber 102; the protrusion 23 can also be other structures, such as a cylinder; the connecting hole 204 can also be other shapes, such as a through hole with a wavy flow channel.

[0053] Please refer to Figure 5In some embodiments, the atomizing body 20 further includes an air guide tube 25 , the atomizing chamber 202 is opened in the air guide tube 25 , the air guide tube 25 penetrates the oil storage chamber 205 and the sealing silicone 24 , and the oil storage chamber 205 circumferentially surrounds the atomizing chamber 202 .

[0054] Through the above structure, the atomization chamber 202 is opened in the air guide tube 25, and the oil storage chamber 205 circumferentially surrounds the atomization chamber 202, so that as many oil inlet holes as possible can be opened on the tube wall of the air guide tube 25 to increase the flow rate of the tobacco oil in the oil storage chamber 205 to the atomization chamber 202, thereby improving the atomization efficiency of the tobacco oil in the atomization chamber 202.

[0055] Specifically, in the present embodiment, the raised portion 23 and the sealing silicone 24 are integrally formed, the cross-section of the air guide tube 25 is circular, the air guide tube 25 includes a coaxially arranged thick tube section 258 and a thin tube section 256 , the atomization chamber 202 is opened in the thick tube section 258 , wherein the thin tube section 256 is penetrated in the sealing silicone 24 .

[0056] In other embodiments, the protrusion 23 can also be formed separately from the sealing silicone 24, and the protrusion 23 is connected to the sealing silicone 24 by snap-fitting or other means; the air guide tube 25 can also be other structures, such as a straight tube with a circular cross-section.

[0057] In some embodiments, the sealing silicone 24 includes an oil storage plane 242 , the air guide tube 25 includes a first end 252 and a second end 254 that are oppositely disposed, the first end 252 is disposed through the oil storage plane 242 and protrudes from the first oil storage chamber 30 , and the atomization chamber 202 is located at the second end 254 .

[0058] Through the above structure, the first end 252 and the raised portion 23 are both raised relative to the oil storage plane 242, so that when the smoke flows through the atomization chamber 202 to the first oil storage chamber 30, the portion of the air guide tube 25 that is raised relative to the oil storage plane 242 hinders the smoke from flowing toward the raised portion 23, further reducing the possibility of the smoke flowing into the airflow control chamber 203 through the connecting hole 204 when the user inhales the aerosol generating device 100.

[0059] Specifically, the end of the thin tube section 256 facing away from the thick tube section 258 is the first end 252, and the end of the thick tube section 258 facing away from the thin tube section 256 is the second end 254. A clearance hole 2402 is opened on the sealing silicone 24, and the first end 252 is penetrated by the clearance hole 2402, and the tube wall of the thin tube section 256 is abutted against the hole wall of the clearance hole 2402, so that the oil storage chamber 205 and the first oil storage chamber 30 are separated from each other.

[0060] Please refer to Figure 6 and Figure 7In some embodiments, the nozzle assembly 10 includes an oil sealing member 12, the oil sealing member 12 faces the atomizing body 20, the sealing silicone 24 is provided with an oil filling hole 2404, the oil filling hole 2404 is connected to the oil storage chamber 205, and the oil sealing member 12 seals the oil filling hole 2404; the central axis of the air guide tube 25, the central axis of the connecting hole 204 and the central axis of the oil filling hole 2404 are parallel to each other and coplanar, and the oil filling hole 2404 is located between the air guide tube 25 and the connecting hole 204.

[0061] Through the above structure, on the one hand, the oil seal 12 can seal the oil filling hole 2404. When the nozzle assembly 10 is installed on the atomizer body 20, the oil seal 12 can be inserted into the oil filling hole 2404 to seal the oil filling hole 2404. On the other hand, the oil seal 12 is located between the air guide pipe 25 and the connecting hole 204, so that the oil seal 12 can prevent the smoke from flowing from the air guide pipe 25 to the connecting hole 204.

[0062] Specifically, the oil seal 12 is a structure similar to a cylinder and is hollow to reduce the overall weight of the nozzle assembly 10 ; when the nozzle assembly 10 is installed on the atomizer body 20 , the side surface of the oil seal 12 abuts against the hole wall of the oil filling hole 2404 .

[0063] In some embodiments, the suction cavity 102 is directly opposite to the first end 252, and the suction cavity 102 and the connecting hole 204 are staggered with each other; the cross-sectional area of ​​the suction cavity 102 is larger than the cross-sectional area of ​​the first end 252, and in the direction from the first end 252 to the suction cavity 102, the projection of the first end 252 is located within the projection of the cross section of the suction cavity 102.

[0064] Through the above structure, when the user inhales the aerosol generating device 100, the first end 252 guides the smoke so that the smoke will not contact the cavity wall of the first oil storage chamber 30 and slow down the flow rate, so that the smoke can directly flow into the suction cavity 102 to increase the amount of smoke inhaled by the user. In addition, since the smoke flowing out of the first end 252 will not contact the cavity wall of the first oil storage chamber 30 and turn back, the possibility of the smoke flowing into the airflow controller 22 through the connecting hole 204 is further reduced.

[0065] Specifically, the cross-sectional area of ​​the suction cavity 102 is larger than the cross-sectional area of ​​the thin tube segment 256 , and along the central axis direction of the thin tube segment 256 , the projection of the cross section of the thin tube segment 256 is located within the projection of the cross section of the suction cavity 102 .

[0066] In some embodiments, the aerosol generating device 100 further includes a switch 40 , which is located on the outer surface of the atomizing body 20 . The switch 40 is electrically connected to the airflow controller 22 , and the switch 40 can control the airflow controller 22 to be turned on or off.

[0067] With the above structure, when the user stops inhaling the aerosol generating device 100 , the user can control the airflow controller 22 to be turned off by pressing the switch member 40 to avoid the airflow controller 22 being started by mistake.

[0068] Specifically, in this embodiment, the switch 40 is a push switch, and the switch 40 is a waist-shaped structure. In other embodiments, the switch 40 can also be other forms of switches, such as a toggle switch; the switch 40 can also be other shapes, such as a circular structure.

[0069] Please refer to Figure 8 , Fig. 9 , Fig.10 and Fig.11 In some embodiments, the atomizing body 20 further includes a shell 26, a first mounting frame 27a, a second mounting frame 27b, a power supply assembly 28 and a circuit board 29, the oil storage chamber 205 is opened on the first mounting frame 27a, the air inlet 201 is opened on the shell 26, the second mounting frame 27b is opened with a second oil storage chamber 2702, the shell 26 is opened with an air inlet chamber 2602, and the air inlet hole 201 is connected to the atomizing chamber 202 via the air inlet chamber 2602 and the second oil storage chamber 2702 in sequence.

[0070] The first mounting bracket 27a, the second mounting bracket 27b and the power supply assembly 28 are all installed in the shell 26; in the direction from the nozzle assembly 10 to the atomizing body 20, the first mounting bracket 27a and the second mounting bracket 27b are arranged in sequence, and the second oil storage chamber 2702 and the atomizing chamber 202 are arranged in sequence; the power supply assembly 28 is located on one side of the oil storage chamber 205, the circuit board 29 is installed in the air inlet chamber 2602, and the airflow controller 22, the heating assembly 21 and the power supply assembly 28 are all electrically connected to the circuit board 29.

[0071] Through the above structure, during the assembly process of the atomizer body 20, it is only necessary to install the second mounting frame 27b and the sealing silicone 24 on the first mounting frame 27a, and then put the shell 26 on the first mounting frame 27a, and finally install the power supply component 28 and the circuit board 29 into the shell 26 to complete the installation of the atomizer body 20; thus, the atomizer body 20 in this embodiment is easy to install.

[0072] In addition, when the user stops inhaling the aerosol generating device 100, the second oil storage chamber 2702 can be used for smoke to condense to form condensed oil, so as to prevent the condensed oil from directly flowing into the air inlet chamber 2602 and contacting the circuit board 29. The power supply assembly 28 is located on one side of the oil storage chamber 205 so that the air flow channel does not pass through the power supply assembly 28, so as to prevent the surface of the power supply assembly 28 from contacting with smoke or condensed oil.

[0073] Specifically, the second end 254 is inserted into the bottom cavity wall of the oil storage cavity 205, the sealing silicone 24 is embedded in one end of the first mounting frame 27a, and the second mounting frame 27b is embedded in the other opposite end of the first mounting frame 27a; the power supply component 28 is a block structure similar to a rectangular parallelepiped, and the power supply component 28 is installed in the space formed by the outer shell 26 and the first mounting frame 27a.

[0074] In some embodiments, the second mounting frame 27b includes an air inlet pipe 2704, the central axis of the air inlet pipe 2704 is colinear with the central axis of the atomization chamber 202; one end of the air inlet pipe 2704 is protruded into the second oil storage chamber 2702, and the other end of the air inlet pipe 2704 is protruded into the air intake chamber 2602, and the air intake chamber 2602 is connected with the second oil storage chamber 2702 via the air inlet pipe 2704.

[0075] Through the above structure, the air inlet pipe 2704 has a guiding effect on the air, and the outside air can flow into the atomizing chamber 202 through the air inlet pipe 2704. In addition, one end of the air inlet pipe 2704 is convexly arranged in the second oil storage chamber 2702. When the user stops inhaling the aerosol generating device 100, the residual smoke in the atomizing chamber 202 is difficult to flow directly into the air inlet pipe 2704, thereby reducing the possibility of the smoke flowing back to the circuit board 29; and the smoke condenses in the second oil storage chamber 2702 to form condensed oil, and the tube wall of the air inlet pipe 2704 has a blocking effect on the condensed oil, so as to prevent the condensed oil from flowing along the air inlet pipe 2704 to the circuit board 29.

[0076] Specifically, in this embodiment, the air inlet pipe 2704 is a circular straight pipe, and the cavity wall of the second oil storage chamber 2702 is an irregular concave-convex structure, so that the condensed oil is difficult to flow along the cavity wall of the second oil storage chamber 2702, and the second oil storage chamber 2702 has a better adsorption effect on the condensed oil. In other embodiments, the air inlet pipe 2704 can also be other structures, such as a truncated cone-shaped tubular structure; the second oil storage chamber 2702 can also be other structures, such as a rectangular parallelepiped.

[0077] In some embodiments, the circuit board 29 is located between the air inlet hole 201 and the air inlet pipe 2704, and the air inlet hole 201 is connected to the air inlet pipe 2704 through the gap between the cavity wall of the air inlet cavity 2602 and the circuit board 29; the air inlet hole 201 and the air inlet pipe 2704 are staggered with each other.

[0078] Through the above structure, the circuit board 29 separates the air inlet hole 201 and the air inlet pipe 2704 from each other, so that when the user does not inhale the aerosol generating device 100 and the heating component 21 is started, for example, there is a gap between two inhalations of the aerosol generating device 100; it is difficult for the airflow to pass through the aerosol generating device 100, and the smoke in the aerosol generating device 100 is difficult to overflow.

[0079] Specifically, in this embodiment, the number of the air inlet holes 201 is two, and the number of the air inlet pipe 2704 is one. In other embodiments, the number of the air inlet holes 201 and the number of the air inlet pipe 2704 can be other.

[0080] In some embodiments, the nozzle assembly 10 includes a mounting side wall 14, which faces the atomizing body 20, and is sleeved on the outer surface of the second mounting frame 27b. The mounting side wall 14 is clamped with the second mounting frame 27b, and the outer shell 26 is sleeved on the outer surface of the mounting side wall 14. The inner surface of the outer shell 26 and the outer surface of the second mounting frame 27b clamp the mounting side wall 14.

[0081] Through the above structure, when the suction nozzle assembly 10 is installed on the atomizer body 20, it is only necessary to insert the installation side wall 14 into the gap between the outer shell 26 and the second mounting frame 27b, and the installation side wall 14 can be mutually engaged with the second mounting frame 27b, and the inner surface of the outer shell 26 and the outer surface of the second mounting frame 27b clamp the installation side wall 14; under the condition of simple assembly, the suction nozzle assembly 10 can be stably installed on the atomizer body 20.

[0082] Specifically, a block 271 is provided on the outer surface of the second mounting frame 27b, and a corresponding slot 104 is opened on the mounting side wall 14. During the process of inserting the mounting side wall 14 into the gap between the outer shell 26 and the second mounting frame 27b, the mounting side wall 14 can abut against the block 271, so that the mounting side wall 14 is slightly tilted until the block 271 cooperates with the corresponding slot 104, and the mounting side wall 14 is reset, and the nozzle assembly 10 and the atomizer body 20 are assembled.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Under the idea of ​​the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity. Although the present invention is described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
