AI Technical Summary
When the user is pumping the aerosol generation device, the less force causes the external airflow and smoke to be insufficiently mixed in the atomization chamber.
An aerosol generator is designed, including an intake passage of the fluid acceleration chamber. By gradually reducing the cross-sectional area of the fluid acceleration chamber, the flow rate of the external gas is increased, so as to mix more fully with the smoke in the atomization chamber.
Through the design of the acceleration chamber, external gases have a faster flow rate when entering the atomization chamber, which significantly improves the mixing uniformity between smoke and external gases, and at the same time, the installation of sound insulation parts reduces noise propagation.

[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. 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.
[0033] 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.
[0034] Please refer to Figure 1 , Figure 2 and Figure 3In 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 inhalation cavity 102. The nozzle assembly 10 includes a sound insulator 12, and the sound insulator 12 is installed in the air inhalation cavity 102. The atomizing body 20 includes a heating component 21. The atomizing body 20 is provided with an air inlet channel 222, an atomizing cavity 201, an air guide cavity 202, an oil storage cavity 203 and an oil inlet hole 204. The nozzle assembly 10 is provided with an air inlet channel 222, an atomizing cavity 201, an air guide cavity 202, an oil storage cavity 203 and an oil inlet hole 204. Installed on the atomizing body 20, the air inlet channel 222 is connected with the air suction chamber 102 via the atomizing chamber 201 and the air guide chamber 202 in sequence, the oil storage chamber 203 is connected with the atomizing chamber 201 via the oil inlet hole 204, the heating component 21 is installed in the atomizing chamber 201, the heating component 21 is located at the oil inlet hole 204, the air inlet channel 222 includes a fluid acceleration chamber 2222; in the direction from the air inlet channel 222 to the atomizing chamber 201, the cross-sectional area of the fluid acceleration chamber 2222 gradually decreases.
[0035] Through the above structure, when the user smokes the electronic cigarette, the oil in the oil storage chamber 203 flows into the atomization chamber 201 through the oil inlet hole 204, and the heating component 21 heats the oil so that the oil is atomized to form smoke in the atomization chamber 201; the outside gas enters the atomization chamber 201 through the air inlet channel 222, and since the cross-sectional area of the fluid acceleration chamber 2222 gradually decreases, the flow rate of the outside gas is accelerated when passing through the fluid acceleration chamber 2222, and then the outside gas has a faster flow rate when entering the atomization chamber 201, and the outside gas can be more fully mixed with the smoke in the atomization chamber 201, so that the smoke and the outside gas are mixed more evenly.
[0036] In addition, the flow rate of the external gas when flowing into the atomization chamber 201 is relatively fast, causing the external gas to emit a louder noise when impacting the cavity wall of the atomization chamber 201 or the gas guide cavity 202. The noise will propagate toward the air intake cavity 102. The sound insulation member 12 is installed in the air intake cavity 102, and the sound insulation member 12 can block the noise, thereby reducing the noise transmitted through the air intake cavity 102.
[0037] Specifically, in the present embodiment, the sound insulation member 12 is a rectangular sheet structure made of cotton. The sound insulation member 12 is installed on the cavity wall of the air intake cavity 102 by gluing. The sound insulation member 12 is located at the connection point between the air guide cavity 202 and the air intake cavity 102. Thus, the sound insulation member 12 can prevent noise from being transmitted into the air intake cavity 102 through the air guide cavity 202.
[0038] The atomizing body 20 has a structure similar to a rectangular parallelepiped, and the atomizing body 20 also includes a power supply component 26. The air inlet channel 222, the atomizing chamber 201, the air guide chamber 202, the oil storage chamber 203 and the oil inlet hole 204 are all located on one side of the atomizing body 20. A power supply installation cavity 208 is opened on the other side of the atomizing body 20. The power supply component 26 is installed in the power supply installation cavity 208, and the power supply component 26 is electrically connected to the heating component 21.
[0039] The heating component 21 is a block structure, and includes a ceramic oil guide, and is embedded in the oil inlet hole 204. The oil storage chamber 203 and the air inlet channel 222 are respectively located at two ends of the atomizing chamber 201, and the air inlet channel 222 faces the heating component 21. The fluid acceleration chamber 2222 is truncated.
[0040] In addition, an air inlet cavity 209 and an air inlet hole 2092 are provided at one end of the atomizing body 20 away from the suction nozzle assembly 10, and the air inlet hole 2092 is connected with the air inlet channel 222 through the air inlet cavity 209; the air inlet hole 2092 and the air inlet channel 222 are respectively located at the two ends of the air inlet cavity 209, and the air inlet hole 2092 and the air inlet channel 222 are staggered with each other.
[0041] In other embodiments, the sound insulation 12 can also be made of other materials, such as sponge or porous plastic; the sound insulation 12 can also be installed on the cavity wall of the inhalation cavity 102 by other means, such as plugging; the atomization body 20 can also have other structures, such as a cylinder; the heating component 21 can also be a cylindrical structure, the heating component 21 includes oil storage cotton and a cylindrical heating net, the oil storage cotton wraps the heating net; the fluid acceleration chamber 2222 can also be other shapes, for example, the side cavity wall of the fluid acceleration chamber 2222 is a curved surface, and the fluid acceleration chamber 2222 is a bowl-shaped structure as a whole.
[0042] Please refer to Figure 4 In some embodiments, the atomizing body 20 further includes an air inlet pipe 22, an air inlet channel 222 is opened in the air inlet pipe 22, the air inlet pipe 22 includes a fluid acceleration end, the fluid acceleration end faces the heating component 21, and the fluid acceleration chamber 2222 is located at the fluid acceleration end.
[0043] Through the above structure, the heating component 21 heats the e-liquid, so that the e-liquid is atomized in the atomization chamber 201. It can be inferred that the smoke concentration at the heating component 21 is relatively large; the fluid acceleration end is directly opposite to the heating component 21, and the fluid acceleration chamber 2222 is located at the fluid acceleration end, so that the external gas can flow quickly toward the heating component 21, and then the external gas can be directly fully mixed with the smoke with a higher concentration, and the external gas and the smoke can be mixed more evenly.
[0044] Specifically, in this embodiment, the air inlet pipe 22 is a straight pipe, and the cross-section of the air inlet pipe 22 is circular. One end of the air inlet pipe 22 passes through the wall of the atomizing chamber 201 away from the oil storage chamber 203, and the central axis of the air inlet pipe 22 is parallel to the direction from the oil storage chamber 203 to the atomizing chamber 201.
[0045] In other embodiments, the air intake pipe 22 may also be other structures, such as a corrugated pipe; the cross-sectional shape of the air intake pipe 22 may also be other shapes, such as an elliptical shape.
[0046] In some embodiments, the atomizing body 20 further includes a protrusion 23, which is connected to the cavity wall of the atomizing cavity 201. The protrusion 23 and the heating component 21 are respectively located at two ends of the atomizing cavity 201. The atomizing body 20 is provided with a receiving cavity 2302, which passes through the protrusion 23, and the air inlet pipe 22 is installed in the receiving cavity 2302.
[0047] Through the above structure, the receiving chamber 2302 passes through the protrusion 23, and the air inlet pipe 22 is installed in the receiving chamber 2302, so that the fluid acceleration end and the bottom wall of the atomization chamber 201 are not located in the same plane; when the user stops inhaling the aerosol generating device 100, there is still residual heat in the heating component 21, and the heating component 21 can also heat the smoke oil, so that part of the smoke oil is atomized. Most of the atomized smoke oil condenses on the cavity wall of the atomization chamber 201 to form condensed oil. Under the action of the protrusion 23, and the area of the fluid acceleration chamber 2222 facing the heating component 21 is small, it is difficult for the condensed oil to flow into the fluid acceleration chamber 2222, and then it is difficult for the condensed oil to flow out of the aerosol generating device 100 through the air inlet channel 222.
[0048] Specifically, in this embodiment, the raised portion 23 is a cylindrical structure, the receiving cavity 2302 is a cylindrical structure, the size of the receiving cavity 2302 is compatible with the size of the air intake pipe 22, and the outer surface of the air intake pipe 22 abuts against the cavity wall of the receiving cavity 2302, so that the air intake pipe 22 is installed in the receiving cavity 2302.
[0049] In other embodiments, the protrusion 23 may also have other structures, such as a rectangular parallelepiped or a hemisphere, and the length of the receiving cavity 2302 may also be smaller than the length of the air intake pipe 22, so that the fluid acceleration end extends out of the receiving cavity 2302; the air intake pipe 22 may also be installed in the receiving cavity 2302 in other ways, such as the outer surface of the air intake pipe 22 and the cavity wall of the receiving cavity 2302 are mutually clamped.
[0050] Please refer to Figure 5 In some embodiments, the air inhalation chamber 102 includes a first air chamber 1022 and a second air chamber 1024, the atomization chamber 201 is connected to the second air chamber 1024 via the air guide chamber 202 and the first air chamber 1022 in sequence, the air guide chamber 202 is located on one side of the oil storage chamber 203, the atomization chamber 201 and the first air chamber 1022 are respectively located at two ends of the oil storage chamber 203, the sound insulation member 12 is installed in the first air chamber 1022, and the air guide chamber 202 is opposite to the sound insulation member 12.
[0051] Through the above structure, the air guide cavity 202 is located on one side of the oil storage cavity 203, and the air guide cavity 202 does not need to pass through the oil storage cavity 203; the oil storage cavity 203 can have a larger volume, and the structure of the aerosol generating device 100 is more compact, and the oil storage cavity 203 of the aerosol generating device 100 is easier to manufacture. The air guide cavity 202 is directly opposite to the sound insulation member 12, so that the sound insulation member 12 can more effectively prevent noise from being transmitted to the first cavity through the air guide cavity 202.
[0052] Specifically, in this embodiment, the first air chamber 1022 is a flat structure similar to a rectangular parallelepiped, the second air chamber 1024 is a cylinder, the second air chamber 1024 and the air guide cavity 202 are respectively located at the two ends of the first air chamber 1022, the oil storage cavity 203 is similar to a rectangular parallelepiped, and the air guide cavity 202 is a strip structure with a waist-shaped cross-section.
[0053] In other embodiments, the first air chamber 1022 and the second air chamber 1024 may be other structures, for example, the first air chamber 1022 is a hemisphere, and the second air chamber 1024 is a cone; the oil storage cavity 203 may also be other shapes, such as a cylinder; the air guide cavity 202 may also be other shapes, such as a cylinder.
[0054] In some embodiments, the central axis of the air guiding cavity 202 is parallel to the central axis of the second air chamber 1024 . The second air chamber 1024 and the air guiding cavity 202 are respectively located at two ends of the first air chamber 1022 and are staggered with each other. The sound insulation member 12 is staggered with the second air chamber 1024 .
[0055] Through the above structure, the second air chamber 1024 and the air guide cavity 202 are respectively located at the two ends of the first air chamber 1022 and staggered with each other, so that after the noise is transmitted to the first air chamber 1022 through the air guide cavity 202, the cavity wall of the first air chamber 1022 can block the noise, thereby further reducing the noise entering the second air chamber 1024. In addition, the mixed gas of smoke and external air turns twice when flowing through the first air chamber 1022, so that the smoke and external air can be further mixed in the first air chamber 1022.
[0056] Specifically, the sound insulation member 12 is installed on one side of the first air chamber 1022, and one side of the sound insulation member 12 is located at the connection point between the air guide cavity 202 and the first air chamber 1022; since the second air chamber 1024 and the air guide cavity 202 are respectively located at the two ends of the first air chamber 1022 and are staggered with each other, the sound insulation member 12 and the second air chamber 1024 are staggered.
[0057] In some embodiments, the sound insulation 12 is a cotton sheet structure.
[0058] Through the above structure, the cotton structure is more fluffy, so that the sound insulation member 12 has a better absorption effect on noise, and thus the sound insulation member 12 can hinder the propagation of noise to a greater extent.
[0059] Specifically, the sound insulation member 12 is in a rectangular sheet-like structure, and the central axis of the air guide cavity 202 is perpendicular to the sound insulation member 12 .
[0060] Please refer to Figure 2 In some embodiments, the aerosol generating device 100 further includes a microphone assembly 30, and the atomizing body 20 further includes a microphone mounting cavity 205 and a connecting cavity 206. The microphone assembly 30 is installed in the microphone mounting cavity 205, and the microphone mounting cavity 205 is connected to the atomizing cavity 201 via the connecting cavity 206, and the connecting cavity 206 is staggered with the microphone assembly 30.
[0061] Through the above structure, the connecting cavity 206 is staggered with the microphone assembly 30, so that the smoke or condensed oil in the atomization cavity 201 is difficult to directly contact the microphone assembly 30, thereby reducing the possibility of smoke oil adhering to the surface of the microphone assembly 30 and causing damage to the microphone assembly 30.
[0062] Specifically, in the present embodiment, the microphone assembly 30 has a structure similar to a cylinder, the microphone assembly 30 is located on one side of the microphone mounting cavity 205, and the connecting cavity 206 is located on the other side of the microphone mounting cavity 205; and the outer surface of the microphone assembly 30 abuts against the cavity wall of the microphone mounting cavity 205, the connecting cavity 206 has a structure similar to a cylinder, and the central axis of the connecting cavity 206 is parallel to the central axis of the microphone mounting cavity 205.
[0063] In other embodiments, the microphone assembly 30 may also be other structures, such as a cuboid; the communicating cavity 206 may also be other structures, such as a cuboid.
[0064] In some embodiments, the atomizing body 20 further includes an air guide tube 24, the microphone mounting cavity 205 and the air guide cavity 202 are respectively located at two ends of the atomizing cavity 201, one end of the air guide tube 24 is inserted into the connecting cavity 206, the outer surface of the air guide tube 24 is in contact with the cavity wall of the connecting cavity 206, the air guide tube 24 is passed through the atomizing cavity 201 and the air guide cavity 202, the other end of the air guide tube 24 is located in the first air chamber 1022, and the microphone mounting cavity 205 is connected with the first air chamber 1022 via the air guide tube 24.
[0065] Through the above structure, the microphone mounting cavity 205 is directly connected to the first air chamber 1022 via the air guide tube 24, and then when the user inhales the aerosol generating device 100, the gas in the microphone mounting cavity 205 can be more directly sucked into the first chamber, so that the microphone assembly 30 can more accurately sense the user inhaling the aerosol generating device 100. In addition, the air guide tube 24 has a blocking effect on the smoke and condensed oil in the atomizing cavity 201, so that the smoke oil and condensed oil in the atomizing cavity 201 cannot directly enter the microphone mounting cavity 205, further reducing the possibility of damage to the microphone assembly 30.
[0066] Specifically, in this embodiment, the air guide tube 24 is a straight tube, the cross-section of the air guide tube 24 is circular, the cross-sectional area of the air guide tube 24 is smaller than the cross-sectional area of the air guide cavity 202 , and there is a gap between the outer surface of the air guide tube 24 and the cavity wall of the air guide cavity 202 .
[0067] In other embodiments, the cross-section of the air guide tube 24 may also be other shapes, such as a rectangle or an ellipse.
[0068] Please refer to Figure 6 and Figure 7 In some embodiments, the nozzle assembly 10 also includes an air intake pipe 16 and an oil filling plug 14, the atomizing body 20 is also provided with an oil filling hole 207, the second air chamber 1024 is opened in the air intake pipe 16, the air intake pipe 16 is provided with an air intake hole 1602, the first air chamber 1022 is connected to the second air chamber 1024 through the air intake hole 1602; the oil filling plug 14 is connected to one end of the air intake pipe 16, the oil filling plug 14 is coaxially arranged with the first air chamber 1022, and the oil filling plug 14 blocks the oil filling hole 207.
[0069] Through the above structure, the oil filling plug 14 is connected to one end of the intake pipe 16, so that the intake pipe 16 and the oil filling plug 14 can be formed as an integral part, reducing the complexity of the structure of the suction nozzle assembly 10, making the suction nozzle assembly 10 easier to manufacture, and the suction hole 1602 is opened in the intake pipe 16, and the intake hole 1602 is located on one side of the second air chamber 1024. The tube wall of the intake pipe 16 can also play a role in blocking noise.
[0070] Specifically, in this embodiment, the oil filling plug 14 has a structure similar to a cylinder, the intake pipe 16 is a straight pipe, the number of intake holes 1602 is two, the two intake holes 1602 are symmetrically distributed relative to the central axis of the intake pipe 16, and the intake holes 1602 are located at one end of the intake pipe 16 facing the oil filling plug 14.
[0071] In other embodiments, the oil filling plug 14 may also be other structures, such as a rectangular parallelepiped; the number of the air suction holes 1602 may also be other numbers, such as one or three.
[0072] In some embodiments, the first air chamber 1022 passes through one end of the nozzle assembly 10 toward the atomizer body 20, and the atomizer body 20 includes a first end surface 25, which is covered on the first air chamber 1022, and the air guide cavity 202 passes through the first end surface 25, and a plurality of waist-shaped grooves 2502 arranged in parallel are opened on the first end surface 25.
[0073] With the above structure, when the user stops inhaling the aerosol generating device 100, the condensed oil formed after the liquefied tobacco oil in the first air chamber 1022 can adhere to the waist-shaped groove 2502, thereby reducing the possibility of the condensed oil flowing back into the air guide cavity 202 or the air guide tube 24.
