[0002] Aerosol generating devices are also known as virtual cigarettes, electronic cigarettes, steam cigarettes, etc. They are mainly used for quitting smoking or replacing cigarettes. Aerosol generating devices heat the smoke oil to atomize it, and the atomized smoke oil flows out from the mouthpiece for customers to inhale.

[0003] In the related art, most aerosol generating devices include an atomizing host, a shell and a power supply assembly. The atomizing host and the shell are connected to each other, and the power supply assembly is installed in the shell.

The oil storage chamber is connected to the air intake chamber through the atomizing chamber. The atomizing host includes a heating component. The power supply assembly is used to supply power to the heating component. The heating component is installed in the atomizing chamber. After the oil in the oil storage chamber flows into the atomizing chamber, the heating component heats the oil so that the oil is atomized in the atomizing chamber to form smoke. When the user inhales the aerosol generating device, the smoke in the atomizing chamber flows out through the air intake chamber and is inhaled by the user.

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.

[0039] 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.

[0040] Please refer to Figure 1 and Figure 2In one embodiment of the utility model, an aerosol generating device 100 is disclosed, including an atomizing host 10, a housing 20 and a power supply assembly 30; the atomizing host 10 includes a main body 11, a heating component 12 and a first oil suction member 13, the main body 11 is provided with an air suction chamber 11242, an atomizing chamber 1102, an air inlet 11402, an oil storage chamber 11222 and an oil inlet 11602, the air inlet 11402 is connected to the air suction chamber 11242 through the atomizing chamber 1102, and the oil storage chamber 11222 is connected to the atomizing chamber 1102 through the oil inlet 11602; the heating component 12 is installed in the atomizing chamber 1102, and is located at the oil inlet hole 11602; the first oil suction member 13 is installed on the cavity wall of the suction cavity 11242, and a plurality of first oil locking grooves 11404 are provided on the side cavity wall of the atomizing cavity 1102, and a plurality of second oil locking grooves 11406 are provided on the bottom cavity wall of the atomizing cavity 1102; the atomizing host 10 is installed on the outer shell 20, and the outer shell 20 is provided with a power supply installation cavity 204 and an air inlet hole 202, and the air inlet hole 202 is connected with the atomizing cavity 1102 through the air inlet hole 11402; the power supply component 30 is installed in the power supply installation cavity 204, and the power supply component 30 is electrically connected to the heating component 12.

[0041] Through the above structure, when the user stops inhaling the aerosol generating device 100, the heating component 12 still has heat, so that the smoke oil will also form smoke in the atomizing chamber 1102, and the smoke condenses in the atomizing chamber 1102 or the air inhalation chamber 11242, and may flow out along the air inhalation chamber 11242, causing oil leakage. The first oil locking groove 11404 makes the side cavity wall of the atomizing chamber 1102 uneven, and the area of ​​the side cavity wall of the atomizing chamber 1102 increases, so that the smoke is more likely to condense on the side cavity wall of the atomizing chamber 1102 and adhere to the first oil locking groove 11404. Similarly, the smoke is also easy to condense at the second oil locking groove 11406 and adhere to the second oil locking groove 11406; thereby reducing the possibility of the condensed oil in the atomizing chamber 1102 flowing out through the air inhalation chamber 11242, and reducing the possibility of oil leakage of the aerosol generating device 100.

[0042] In addition, if condensed oil flows through the atomization chamber 1102 to the air inhalation chamber 11242, or the smoke oil forms condensed oil in the air inhalation chamber 11242, causing the condensed oil to adhere to the cavity wall of the air inhalation chamber 11242, the first oil absorption member 13 can absorb the condensed oil on the cavity wall of the air inhalation chamber 11242, thereby reducing the possibility of the condensed oil in the air inhalation chamber 11242 flowing out, and further reducing the possibility of oil leakage of the aerosol generating device 100.

[0043] Specifically, in the present embodiment, the air intake chamber 11242 is cylindrical, the oil storage chamber 11222 is arranged around the air intake chamber 11242, and the oil inlet hole 11602 and the air intake chamber 11242 are both connected to the top of the atomization chamber 1102; the heating component 12 includes a sheet-shaped heating net and a block-shaped ceramic oil guide member, and the heating component 12 is a structure similar to a rectangular parallelepiped as a whole. The heating component 12 is located at the top of the atomization chamber 1102, and the air intake hole 11402 is a circular through hole. One end of the air intake hole 11402 passes through the bottom cavity wall of the atomization chamber 1102, and the other end of the air intake hole 11402 passes through the top cavity of the power supply installation cavity 204. Wall; the number of the first oil locking grooves 11404 and the number of the second oil locking grooves 11406 are both multiple, the first oil locking grooves 11404 and the second oil locking grooves 11406 are both linear strip structures, all the first oil locking grooves 11404 are arranged side by side, and all the second oil locking grooves 11406 are also arranged side by side; the power supply component 30 has a structure similar to a rectangular parallelepiped, the shape of the power supply installation cavity 204 is adapted to the shape of the power supply component 30, the air inlet 202 is a circular through hole, the air inlet 202 passes through the bottom cavity wall of the power supply installation cavity 204, and the central axis of the air inlet 202 is parallel to the central axis of the air inlet 11402.

[0044] In other embodiments, the air intake chamber 11242 may also be other structures, such as a column with an elliptical cross-section; the oil storage chamber 11222 and the air intake chamber 11242 may also be located on both sides of the atomizer host 10 respectively; the heating component 12 may also include a cylindrical heating net and a cylindrical oil guide cotton, and the heating component may also be installed on the side cavity wall of the atomizer chamber 1102; the air inlet hole 11402 may also be other shapes, such as a rectangular parallelepiped; the first oil lock groove 11404 and the second oil lock groove 11406 may also be other structures, such as a wavy strip structure; the power supply assembly 30 may also be other structures, such as a cylinder; the air inlet hole 202 may also be other shapes, such as an elliptical through hole, and the air inlet hole 202 may also be opened on the side cavity wall of the power supply installation cavity 204, and the central axis of the air inlet hole 202 may not be parallel to the central axis of the air inlet hole 11402.

[0045] Please refer to Figure 3 and Figure 4 In some embodiments, the main body 11 includes a suction nozzle component 112, a first mounting seat 114 and a second mounting seat 116, the second mounting seat 116 is installed on the first mounting seat 114, and the suction nozzle component 112 is installed on the first mounting seat 114 and is sleeved on the second mounting seat 116; the suction chamber 11242 and the oil storage chamber 11222 are opened in the suction nozzle component 112, the first mounting seat 114 and the second mounting seat 116 are surrounded to form an atomization chamber 1102, the oil inlet hole 11602 is opened in the second mounting seat 116, and the air inlet hole 11402, the first oil locking groove 11404 and the second oil locking groove 11406 are opened in the first mounting seat 114.

[0046] The second mounting seat 116 is provided with an air guiding cavity 11604 , and the atomizing cavity 1102 is connected with the air inhalation cavity 11242 via the air guiding cavity 11604 . A third oil locking groove 11609 is provided on the cavity wall of the air guiding cavity 11604 .

[0047] Through the above structure, during the assembly process of the atomizer host 10, the heating component 12 is first installed on the second mounting seat 116, and the first oil suction component 13 is installed on the suction nozzle component 112; then the first mounting seat 114 is installed on the second mounting seat 116, and the suction nozzle component 112 is installed on the first mounting seat 114, and is sleeved on the second mounting seat 116, and the installation of the atomizer host 10 can be completed, making the installation steps of the atomizer host 10 more convenient.

[0048] In addition, when the condensed oil in the atomization chamber 1102 flows to the air intake chamber 11242, it flows through the air guide chamber 11604. The third oil locking groove 11609 makes the cavity wall of the air guide chamber 11604 uneven. As a result, when the condensed oil flows through the cavity wall of the air guide chamber 11604, the condensed oil is easy to adhere to the third oil locking groove 11609, further reducing the possibility of the condensed oil in the atomization chamber 1102 flowing into the air intake chamber 11242.

[0049] Specifically, in this embodiment, the second mounting seat 116 is sleeved on the first mounting seat 114 by interference fit, and a sealing rubber ring is provided between the first mounting seat 114 and the second mounting seat 116, and a sealing rubber ring is also provided between the suction nozzle component 112 and the second mounting seat 116, and the suction nozzle component 112 is connected to the housing 20 by snapping. There are two air guide cavities 11604, and the two air guide cavities 11604 are symmetrically arranged relative to the central axis of the suction cavity 11242; the third oil lock grooves 11609 are in a linear strip structure, and all the third oil lock grooves 11609 are arranged in parallel.

[0050] In other embodiments, the second mounting seat 116 can also be connected to the first mounting seat 114 by other means, such as snap-on; the suction nozzle component 112 can also be connected to the housing 20 by other means, such as gluing; the number of air guide cavities 11604 can also be other, such as one; the third oil lock groove 11609 can also be other shapes, such as a wave shape or a circular ring shape.

[0051] Please refer to Figure 5 In some embodiments, the number of oil inlet holes 11602 and the number of air guide cavities 11604 are both two groups, the two groups of oil inlet holes 11602 are respectively located on two opposite sides of the heating component 12, and the two groups of air guide cavities 11604 are also respectively located on two opposite sides of the heating component 12; the direction from one group of oil inlet holes 11602 to another group of oil inlet holes 11602 is perpendicular to the direction from one group of air guide cavities 11604 to another group of air guide cavities 11604.

[0052] Through the above structure, the smoke oil in the oil storage chamber 11222 can flow to the heating component 12 through the two groups of oil inlet holes 11602 at the same time, so that the smoke oil can adhere to the surface of the heating component 12 more evenly, the smoke oil is heated more evenly, and then the smoke oil can be more fully atomized in the atomization chamber 1102 to form smoke.

[0053] In addition, when the user inhales the aerosol generating device 100, the outside gas flows into the atomizing chamber 1102 through the air inlet 202 and the air inlet 11402, and mixes with the smoke in the atomizing chamber 1102; the mixed gas of the outside gas and the smoke can flow into the inhalation chamber 11242 through the two groups of air guide chambers 11604 at the same time. The flow directions of the mixed gas are different when it flows into the inhalation chamber 11242 through different air guide chambers 11604, and thus the outside gas and the smoke can be further mixed in the inhalation chamber 11242.

[0054] Specifically, in this embodiment, each group of oil inlet holes 11602 includes one oil inlet hole 11602, each group of air guide cavities 11604 includes one air guide cavity 11604, and the oil inlet hole 11602 is a rectangular through hole. In other embodiments, each group of oil inlet holes 11602 may also include other numbers of oil inlet holes 11602, such as two or three; each group of air guide cavities 11604 may also include other numbers of air guide cavities 11604, such as two or three; the oil inlet hole 11602 may also be other shapes, such as a circular through hole.

[0055] Please refer to Figure 6 and Figure 7 In some embodiments, the air guide cavity 11604 includes a first cavity 11605 and a second cavity 11606, and the atomization cavity 1102 is connected to the air inhalation cavity 11242 via the first cavity 11605 and the second cavity 11606 in sequence. The center line of the first cavity 11605 is parallel to the center axis of the air inhalation cavity 11242, and the center line of the second cavity 11606 is perpendicular to the center axis of the air inhalation cavity 11242.

[0056] Through the above structure, when the user inhales the aerosol generating device 100, the flow direction of the smoke and the external gas will change during the process of flowing into the second cavity 11606 through the first cavity 11605, and the smoke and the external gas will be buffered in the gas guide cavity 11604; this makes the smoke and the external gas have a lower flow rate when flowing into the inhalation cavity 11242, and the smoke and the external gas can be further mixed in the gas guide cavity 11604.

[0057] Specifically, the central axes of the two first cavities 11605 are parallel to each other, and the central axes of the two second cavities 11606 are collinear. In this embodiment, the first cavity 11605 and the second cavity 11606 are both in a shape similar to a cuboid; in other embodiments, the first cavity 11605 and the second cavity 11606 can also be in other shapes, such as a cylinder.

[0058] Please refer to Figure 8 In some embodiments, the atomizing host 10 further includes a second oil suction member 14, which is installed in the atomizing chamber 1102 (see Figure 2 ), the bottom cavity wall of the atomizing cavity 1102 is located on the first mounting seat 114 , and the second mounting seat 116 and the bottom cavity wall of the atomizing cavity 1102 clamp the second oil absorbing member 14 .

[0059] Through the above structure, when the user stops inhaling the aerosol generating device 100, the second oil absorbing member 14 can absorb the remaining smoke in the atomizing chamber 1102, reducing the possibility of the smoke forming condensed oil on the cavity wall of the atomizing chamber 1102, thereby reducing the possibility of oil leakage of the aerosol generating device 100. In addition, the second mounting seat 116 and the bottom cavity wall of the atomizing chamber 1102 clamp the second oil absorbing member 14, so that the second oil absorbing member 14 does not need to be installed in the atomizing chamber 1102 through additional parts, simplifying the assembly process of the aerosol generating device 100.

[0060] Specifically, in the present embodiment, the second oil absorbing member 14 is a sheet of oil absorbing cotton; in other embodiments, the second oil absorbing member 14 may also be made of other materials, such as silica gel or flexible cotton material.

[0061] Please refer to Figure 2 and Figure 6 In some embodiments, the atomizer host 10 also includes a third oil suction member 15 and a fourth oil suction member 16, and the main body 11 is also provided with a first oil locking chamber 1104 and a second oil locking chamber 1106, the first oil locking chamber 1104 is connected with the second oil locking chamber 1106 through the atomization chamber 1102, the first oil locking chamber 1104 and the second oil locking chamber 1106 are respectively located on both sides of the atomization chamber 1102, and the two ends of the second oil suction member 14 extend into the first oil locking chamber 1104 and the second oil locking chamber 1106 respectively.

[0062] The third oil suction member 15 is installed in the first oil locking chamber 1104 , and the fourth oil suction member 16 is installed in the second oil locking chamber 1106 . The third oil suction member 15 and the fourth oil suction member 16 are both in contact with the end surface of the bottom cavity wall of the second oil suction member 14 away from the atomizing cavity 1102 .

[0063] Through the above structure, after the second oil absorption member 14 absorbs the smoke in the atomization chamber 1102, the smoke in the second oil absorption member 14 can flow to the third oil absorption member 15 and the fourth oil absorption member 16, and then the second oil absorption member 14, the third oil absorption member 15 and the fourth oil absorption member 16 can absorb more condensed oil, and finally further reduce the possibility of oil leakage of the aerosol generating device 100.

[0064] In addition, the first oil locking chamber 1104 is separated from the atomizing chamber 1102, and the second oil locking chamber 1106 is also separated from the atomizing chamber 1102. The smoke in the atomizing chamber 1102 will not directly contact the third oil absorption component 15 or the fourth oil absorption component 16; therefore, when the user inhales the aerosol generating device 100, the third oil absorption component 15 and the fourth oil absorption component 16 will not absorb the smoke and cause the smoke concentration in the atomizing chamber 1102 to decrease.

[0065] Specifically, in the present embodiment, the third oil absorbing member 15 and the fourth oil absorbing member 16 are both rectangular block structures, the volumes of the third oil absorbing member 15 and the fourth oil absorbing member 16 are different, the shape of the first oil locking chamber 1104 is adapted to the shape of the third oil absorbing member 15, and the cavity wall of the first oil locking chamber 1104 is abutted against the third oil absorbing member 15; the shape of the second oil locking chamber 1106 is adapted to the shape of the fourth oil absorbing member 16, and the cavity wall of the second oil locking chamber 1106 is abutted against the fourth oil absorbing member 16.

[0066] In other embodiments, the third oil absorbing member 15 and the fourth oil absorbing member 16 may be other structures. For example, the third oil absorbing member 15 is cylindrical and the fourth oil absorbing member 16 is spherical. The volume of the third oil absorbing member 15 may also be the same as that of the fourth oil absorbing member 16.

[0067] Please refer to Figure 4 and Figure 6 In some embodiments, the second mounting seat 116 includes a first partition wall 1162 and a second partition wall 1164, both of which are in contact with one end surface of the second oil-absorbing member 14, and the bottom cavity wall of the atomization cavity 1102 is in contact with the other end surface of the second oil-absorbing member 14.

[0068] The first mounting seat 114 includes an annular wall 1144, the first oil locking groove 11404 is opened in the annular wall 1144, the atomization chamber 1102 is formed between the annular wall 1144, the first partition wall 1162 and the second partition wall 1164, the first oil locking chamber 1104 is formed between the first partition wall 1162 and the annular wall 1144, and the second oil locking chamber 1106 is formed between the second partition wall 1164 and the annular wall 1144.

[0069] Through the above structure, the second mounting seat 116 includes a first partition wall 1162 and a second partition wall 1164. The first partition wall 1162 separates the atomizing chamber 1102 from the first oil locking chamber 1104, and the second partition wall 1164 separates the atomizing chamber 1102 from the second oil locking chamber 1106. Therefore, when the second mounting seat 116 is installed on the first mounting seat 114, the atomizing chamber 1102, the first oil locking chamber 1104 and the second oil locking chamber 1106 can be formed; no additional parts for separation are required between the atomizing chamber 1102 and the first oil locking chamber 1104, and between the atomizing chamber 1102 and the second oil locking chamber 1106; at the same time, the first partition wall 1162, the second partition wall 1164 and the bottom cavity wall of the atomizing chamber 1102 can clamp the second oil suction member 14; the structure of the atomizing host 10 is more concise, and the assembly process of the atomizing host 10 is further simplified.

The condensed oil attached to the bottom cavity wall of the atomization cavity 1102 is difficult to flow into the air inlet hole 11402, and then the condensed oil is difficult to flow into the power supply installation cavity 204 through the air inlet hole 11402, so that the surface of the power supply component 30 is not easy to contact the condensed oil, thereby reducing the possibility of damage to the power supply component 30.

[0074] Specifically, in this embodiment, the protrusion 1142 is a cylindrical structure, and the air inlet 11402 passes through the top of the protrusion 1142. In other embodiments, the protrusion 1142 can also be other structures, such as a cuboid, and the air inlet 11402 can also pass through the side surface of the protrusion 1142.

[0076] Through the above structure, during the assembly process of the aerosol generating device 100, when the nozzle body 1122 is installed on the first mounting seat 114 and sleeved on the second mounting seat 116, the end of the air guide tube 1124 can be inserted into the mounting hole 11608, so that the atomization chamber 1102 is connected with the inhalation chamber 11242, making the aerosol generating device 100 easier to assemble.

[0077] Specifically, in the present embodiment, the nozzle body 1122 and the air guide tube 1124 are integrally formed, the cross section of the air guide tube 1124 is circular, and the air guide tube 1124 is a straight tube, and one end of the air guide tube 1124 installed in the mounting hole 11608 is provided with a constriction, and the shape of the mounting hole 11608 is adapted to the shape of the constriction at the end of the air guide tube 1124. In other embodiments, the nozzle body 1122 can also be formed separately from the air guide tube 1124, and the air guide tube 1124 is connected to the nozzle body 1122. The connection method of the air guide tube 1124 and the nozzle body 1122 can be plug-in or clip-on; the cross section of the air guide tube 1124 can also be other shapes, such as rectangular or elliptical.

[0079] Through the above structure, the first oil absorption member 13 can absorb the condensed oil in the suction chamber 11242 , and at the same time, the first oil absorption member 13 will not hinder the gas from flowing out through the suction chamber 11242 .

[0080] Specifically, the air suction cavity 11242 is a cylindrical structure, the inner diameter of the first oil suction member 13 is equal to the diameter of the air suction cavity 11242, and the air suction cavity 11242 is coaxially arranged with the first oil suction member 13. In this embodiment, the first oil suction member 13 is made of oil-absorbing cotton; in other embodiments, the first oil suction member 13 can also be made of other materials, such as sponge.
