[0036] In the description of the embodiments of the present application, it should be noted that the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more.

[0037] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The present application embodiment provides an atomizer 1, see Figures 1 to 6 The atomizer 1 includes an atomizing component 12 and a medium shaping device 11, and the atomizing component 12 has an atomizing chamber 12a.

[0039] An embodiment of the present application provides an aerosol generating device, comprising a power supply assembly and an atomizer 1 of any embodiment of the present application.

[0040] The aerosol generating device is used to atomize the aerosol generating substrate to generate an aerosol for the user to use. The aerosol generating substrate includes but is not limited to medicines, nicotine-containing materials or nicotine-free materials, etc. The aerosol generating substrate can be a solid material with plants as the main raw material, such as tobacco, and added with corresponding aerosol formers and aroma materials.

[0041] The medium shaping device 11 comprises a housing 111 and a pushing mechanism 112 . The housing 111 has a containing cavity 111 a , in which the atomized medium 1 a to be shaped is contained.

[0042] The accommodating cavity 111a can provide a storage space for the atomized medium 1a to be formed. When the atomizer 1 is not in use, the accommodating cavity 111a can store the atomized medium 1a to be formed, thereby reducing the probability of the atomized medium 1a to be formed being dried or oxidized and extending the shelf life.

[0043] It should be noted that the atomized medium 1a to be formed includes an aerosol generating matrix, which can be atomized by heat to produce an aerosol. However, the shape stability of the atomized medium 1a to be formed is low, it does not have a fixed shape, and it is easy to deform under the action of external force. For example, the atomized medium 1a to be formed is in the form of a paste, loose particles, loose sheets, loose filaments, etc. If it is set in the atomization chamber, it is easy to fall out of the atomization chamber due to the shaking of the atomizer during transportation and use.

[0044] The pushing mechanism 112 is at least partially disposed in the accommodating chamber 111 a and is used to push the atomized medium 1 a to be formed in the accommodating chamber 111 a into the atomizing chamber 12 a to obtain a formed medium segment 1 b.

[0045] Specifically, the atomized medium 1a to be formed in the accommodating chamber 111a moves toward the direction close to the atomizing chamber 12a under the pushing action of the pushing mechanism 112, and is formed so that the medium structure in the atomizing chamber 12a is a formed medium segment 1b. The atomizing component 12 is electrically connected to the power supply component, and the power supply component can supply power to the atomizing component 12. The atomizing component 12 converts electrical energy into thermal energy, and the medium segment 1b in the atomizing chamber 12a can be converted into an aerosol that can be used by the user under the action of thermal energy.

[0046] It should be noted that the formed medium segment 1b has a certain structural strength and a fixed appearance. After the atomization is completed, it can be taken out relatively intact without scattering debris everywhere, which is convenient for cleaning the atomization chamber 12a. It is also not easy to escape from the atomization chamber 12a during use. It is understandable that there is a certain force between the medium segment 1b located in the atomization chamber 12a and the inner wall of the atomization chamber 12a to suppress the tendency of the medium segment 1b to move in the atomization chamber 12a. For example, the outer surface of the medium segment 1b fits the inner wall of the atomization chamber 12a, and the position of the medium segment 1b is fixed by the friction between the outer surface of the medium segment 1b and the inner wall of the atomization chamber 12a, thereby suppressing the movement of the medium segment 1b due to the shaking of the atomizer 1 during use.

[0047] It is understandable that the pushing mechanism 112 is at least partially disposed in the accommodating chamber 111a, and a part of the structure of the pushing mechanism 112 may be disposed in the accommodating chamber 111a, or the entire structure of the pushing mechanism 112 may be disposed in the accommodating chamber 111a.

[0048] In the related art, the molding of the atomized medium to be molded is carried out separately from the production of the atomizer, and the production process of the medium segment is complicated. The molded medium segment is placed in a storage box, and the user needs to carry the atomizer and the storage box at the same time. When in use, the medium segment is taken out of the storage box and placed in the atomizer to generate an aerosol for the user, which affects the user experience.

[0049] The atomizer 1 provided in the embodiment of the present application directly places the atomized medium 1a to be formed into the accommodating chamber 111a before use. When suction is required, the atomized medium 1a to be formed can move toward the atomizing chamber 12a and be formed under the action of the pushing mechanism 112 to form a medium segment 1b with a certain structural strength and shape retention. The medium segment 1b is heated and atomized in the atomizing chamber 12a to generate an aerosol for use by the user; the storage, shaping and atomization of the atomized medium 1a to be formed and the formed medium segment 1b are all achieved in the atomizer 1, with a high degree of integration, and there is no need to additionally process and shape the atomized medium to be formed and then put the formed medium segment into a storage box, which saves assembly steps, and the atomizer 1 is easy to use. When using it, the user only needs to carry the atomizer 1, and there is no need to carry an additional storage box for storing the medium segment, so that the user has a better user experience.

[0050] It can be understood that the pushing mechanism 112 pushes the to-be-formed atomized medium 1a in the accommodating chamber 111a into the atomizing chamber 12a to obtain a formed medium segment 1b. The forming method of the to-be-formed atomized medium 1a is not limited. The structure on the side of the accommodating chamber 111a close to the atomizing chamber 12a may have a forming function, so that when the pushing mechanism 112 pushes the to-be-formed atomized medium 1a, the to-be-formed atomized medium 1a can be formed into a medium segment 1b with the assistance of the structure on the side of the accommodating chamber 111a close to the atomizing chamber 12a, thereby entering the atomizing chamber 12a; or the medium forming device 11 may be provided with other components for forming the to-be-formed atomized medium 1a.

[0051] For example, in some embodiments, see Figure 2 , Figure 3 , Figure 5 and Figure 6 The medium shaping device 11 includes a shaping mold 113, which is arranged at one end of the accommodating cavity 111a close to the atomizing assembly 12. The shaping mold 113 has a shaping channel 113a connected to the accommodating cavity 111a. The pushing mechanism 112 is used to extrude the atomized medium 1a to be shaped in the accommodating cavity 111a into the atomizing cavity 12a through the shaping channel 113a.

[0052] In this embodiment, the molding mold 113 is used to mold the atomized medium 1a to be molded, so that the medium structure output through the molding channel 113a is a medium segment 1b with a certain structural strength and a fixed shape. The atomized medium 1a to be molded is first molded through the molding channel 113a under the push of the pushing mechanism 112, and then enters the atomization chamber 12a, so that the medium structure in the atomization chamber 12a is the molded medium segment 1b.

[0053] The molding die 113 can mold the atomized medium 1a to be molded by extrusion molding. The molding method is simple and convenient, and the atomizer 1 is more convenient to use.

[0054] For some examples, see Figures 1 to 6 The atomizer 1 includes a cutting member 114, which is disposed at one end of the accommodating chamber 111a close to the atomizing assembly 12 and is used to cut off the medium segment 1b so that the medium segment 1b in the atomizing chamber 12a is an independent medium structure.

[0055] It should be noted that the medium segment 1b in the atomizing chamber 12a is an independent medium structure, which means that the medium segment 1b located in the atomizing chamber 12a is separated from the medium forming device 11, that is, separated from the forming mold 113 and the housing 111, and is no longer pushed by the pushing mechanism 112, and is independently located in the atomizing chamber 12a. That is to say, in this embodiment, after the atomized medium 1a to be formed in the accommodating chamber 111a is formed, it can be separated from the medium forming device 11 under the action of the cutting member 114, and is not adhered to the atomized medium 1a to be formed in the accommodating chamber 111a, and is independently heated and atomized in the atomizing chamber 12a.

[0056] It should be noted that when the atomized medium 1a to be formed moves toward the side close to the atomization chamber 12a under the push of the pushing mechanism 112, is formed and enters the atomization chamber 12a, the cutting piece 114 is in an avoidance state, that is, the cutting piece 114 does not affect the movement of the formed medium segment 1b at this time. When enough medium segments 1b enter the atomization chamber 12a, the cutting piece 114 is in a cut-off state, so that the medium segment 1b entering the atomization chamber 12a becomes an independent medium structure.

[0057] When the medium segment 1b in the atomizing chamber 12a is completely atomized, the user can take out the used medium segment 1b, and the pushing mechanism 112 moves again to transport the paste medium 1a to be formed toward the side close to the atomizing chamber 12a, form it and enter the atomizing chamber 12a, and the cutting piece 114 cuts off the formed medium segment 1b, and an unused independent medium segment 1b is formed in the atomizing chamber 12a, and a new round of atomization is carried out to generate aerosol. In this way, the user only needs to carry the atomizer 1 to achieve multiple rounds of suction, and the user's suction needs can be met without frequently taking and placing the atomized medium, thereby improving the user's usage experience.

[0058] It can be understood that in some embodiments, an atomization medium detection mechanism can also be installed in the atomization chamber 12a, and the atomization medium detection mechanism can detect the content of the aerosol generating matrix on the surface or inside the medium segment 1b. When the content of the aerosol generating matrix on the surface or inside the medium segment 1b is low, the user can take out the used medium segment 1b, and the pushing mechanism 112 transports the atomized medium 1a to be formed toward the side close to the atomization chamber 12a, shapes it and enters the atomization chamber 12a. After being cut off by the cutting piece 114, an unused independent medium segment 1b is formed in the atomization chamber 12a for use by the user.

[0059] The cutting member 114 may be controlled in any manner, and may be manually controlled or electrically controlled, which is not limited here.

[0060] It should be noted that the location of the cutting member 114 is not limited, as long as it is located at the outlet side of the forming channel 113a and cuts off the formed medium segment 1b. For example, in some examples, the cutting member 114 can be sandwiched between the housing 111 and the atomizing assembly 12, in other examples, the cutting member 114 can also be arranged at the location of the accommodating chamber 111a at the outlet side of the forming channel 113a, and in still other examples, the cutting member 114 is arranged on the side of the atomizing chamber 12a close to the housing 111.

[0061] For some examples, see Figure 3 and Figure 6 When the cutting member 114 is located at the position of cutting off the medium segment 1b, the cutting member 114 closes one end of the atomizing chamber 12a close to the accommodating chamber 111a.

[0062] On the one hand, the end of the atomizing chamber 12a close to the accommodating chamber 111a is in a closed state, which can ensure that there is sufficient negative pressure in the atomizing chamber 12a, making it easy to extract the aerosol and reducing the need for suction negative pressure. The aerosol flows out toward the end of the atomizing chamber 12a away from the accommodating chamber 111a for the user to inhale, thereby reducing the probability of the aerosol overflowing from the end of the atomizing chamber 12a close to the accommodating chamber 111a and increasing the utilization rate of the aerosol; on the other hand, it can also reduce the probability of the aerosol flowing from the end of the atomizing chamber 12a close to the accommodating chamber 111a to the accommodating chamber 111a and affecting the to-be-formed atomized medium 1a located in the accommodating chamber 111a, thereby ensuring the use quality of the to-be-formed atomized medium 1a in the accommodating chamber 111a. The end of the atomizing chamber 12a close to the accommodating chamber 111a is closed by the cutting piece 114, and there is no need to set up an additional structure to close the end of the atomizing chamber 12a close to the accommodating chamber 111a. The overall structure of the atomizer 1 is simpler and more compact.

[0063] The cross-sectional shape of the medium segment 1b is not limited and may be circular, rectangular, elliptical, etc. For example, in some examples, the cross-sectional shape of the medium segment 1b is circular, and the medium segment 1b as a whole is cylindrical; in other embodiments, the cross-sectional shape of the medium segment 1b is rectangular, and the medium segment 1b as a whole is a rectangular column.

[0064] For some examples, see Figures 1 to 6 The medium segment 1b has one or more airway holes 1c, and the airway holes 1c penetrate at least one end of the medium segment 1b along the length direction.

[0065] That is to say, when the aerosol-generating matrix on the surface or inside of the medium segment 1b is atomized by the atomization component 12 to generate aerosol, the aerosol can be released directly from the airway hole 1c. After entering the airway hole 1c, the aerosol can move in the airway hole 1c. When the user inhales to generate negative pressure, the aerosol can flow out of the airway hole 1c under the action of the negative pressure and be used by the user. The airway hole 1c can provide sufficient release space for the aerosol.

[0066] In addition, the provision of the airway hole 1c also facilitates reducing the weight and thickness of the medium segment 1b, and facilitates the heated atomization of the medium segment 1b, so that the aerosol generating matrix on the surface or inside of the medium segment 1b can be fully atomized, and the atomization waiting time is short, so that the user experience is better.

[0067] It can be understood that the airway hole 1c penetrates at least one end of the medium segment 1b along the length direction, and can be one end of the medium segment 1b along the length direction, or can be both ends of the medium segment 1b along the length direction. For example, in some examples, the airway hole 1c penetrates one end of the aerosol generating medium along the length direction, that is, the airway hole 1c is formed as a blind hole, one end is open, and the other end is closed, and the aerosol generated by the aerosol generating matrix on the surface or inside of the medium segment 1b after atomization can flow out from the open end under the action of the suction negative pressure for the user to use; in other examples, the airway hole 1c penetrates both ends of the medium segment 1b along the length direction, that is, the airway hole 1c is formed as a through hole, both ends are open, and the aerosol generated by the aerosol generating matrix on the surface or inside of the medium segment 1b after atomization can flow out from both ends under the action of the suction negative pressure for the user to use, so that the flow rate of the aerosol is faster, and there is enough aerosol for the user to use per unit time.

[0068] It should be noted that the multiple airway holes 1c can be two, three or more than three airway holes 1c, and the shape of the airway holes 1c is not limited, and can be any other shape such as fan-shaped, rectangular, elliptical, etc., and is not limited here.

[0069] The method of taking out the used medium segment 1b is not limited.

[0070] For some examples, see Figures 1 to 6 The atomizing chamber 12a has a first opening 12b on one side away from the accommodating chamber 111a. The atomizer 1 includes a nozzle 13, which is detachably connected to the atomizing assembly 12, that is, the nozzle 13 is detachably connected to one end of the atomizing assembly 12 away from the accommodating chamber 111a. When the nozzle 13 is separated from the atomizing assembly 12, the medium segment 1b can be removed through the first opening 12b.

[0071] Specifically, during atomization, the aerosol generated by atomization can flow out from the suction nozzle 13 through the first opening 12b for the user to inhale. After the aerosol-generating matrix on the surface or inside of the medium segment 1b is atomized, the user can remove the suction nozzle 13 from the atomization component 12 and directly move the used medium segment 1b out of the first opening 12b of the atomization chamber 12a. After the used medium segment 1b is moved out, the suction nozzle 13 is connected to the atomization component 12, and the pushing mechanism 112 continues to transport, shape and enter the atomization chamber 12a the atomized medium 1a to be formed in the accommodating chamber 111a. The cutting piece 114 cuts off the medium segment 1b to form a new, unused, independent medium segment 1b, so that the user can perform a new round of inhalation. In this way, the atomizer 1 is more convenient to use.

[0072] The detachable connection method between the nozzle 13 and the atomizer assembly 12 is not limited, and can be a snap connection, a sleeve connection, etc.

[0073] In some embodiments, the atomizer 1 includes a driving mechanism, which is located on a side of the housing 111 away from the atomizing assembly 12 , and is connected to an end of the pushing mechanism 112 away from the atomizing assembly 12 to drive the pushing mechanism 112 to move.

[0074] That is, the driving mechanism is used to apply force to the pushing mechanism 112 to drive the pushing mechanism 112 to move, so that the pushing mechanism 112 can drive the atomized medium 1a to be formed in the accommodating chamber 111a to be transported toward the side close to the atomizing chamber 12, formed and enter the atomizing chamber 12a.

[0075] It should be noted that the driving mechanism drives the pushing mechanism 112 to move. The driving mechanism can drive the pushing mechanism 112 to rotate, and the atomized medium 1a to be formed in the accommodating chamber 111a is transported toward the side close to the atomizing chamber 12 through rotation, and is formed and enters the atomizing chamber 12a. The driving mechanism can also drive the pushing mechanism 112 to move linearly toward the side close to the atomizing chamber 12a, and the atomized medium 1a to be formed in the accommodating chamber 111a is transported toward the side close to the atomizing chamber 12 through linear motion, and is formed and enters the atomizing chamber 12a.

[0076] The specific structures of the driving mechanism and the pushing mechanism 112 are not limited.

[0077] For some examples, see Figures 1 to 3 The pushing mechanism 112 is an extrusion screw, and the driving mechanism is a knob 14 .

[0078] That is to say, in this embodiment, the driving mechanism drives the pushing mechanism 112 to rotate. By twisting the knob 14, the extrusion screw can be driven to rotate, and the extrusion screw can extrude and mix the atomized medium 1a to be formed in the accommodating chamber 111a. The extrusion screw has threads, and the threads of the extrusion screw can cooperate with the side wall of the accommodating chamber 111a. When rotating, the atomized medium 1a to be formed is mixed and continuously extruded and pushed toward the side close to the atomizing chamber 12a. After the atomized medium 1a to be formed is formed, the formed medium segment 1b continues to enter the atomizing chamber 12a under the push of the extrusion screw for atomization.

[0079] The knob 14 and the extrusion screw are simple to cooperate with, and the operation is convenient and quick, which can enhance the user experience.

[0080] It can be understood that the knob 14 can drive the extrusion screw to rotate. The extrusion screw can rotate in a clockwise direction along the circumference, or it can rotate in a counterclockwise direction along the circumference.

[0081] The number of extrusion screws is unlimited.

[0082] In some examples, the number of the extrusion screw is one, so that the demand for the driving force required to be generated by the knob 14 can be reduced, and the structural reliability can be increased.

[0083] In other examples, there are multiple extrusion screws, and the atomizer 1 includes multiple gears 15, two adjacent gears 15 are meshed, one end of the extrusion screw away from the atomization assembly 12 is connected to the corresponding gear 15, and at least one gear 15 is connected to the knob 14 to drive the multiple extrusion screws to rotate when the knob 14 is rotated.

[0084] In this embodiment, with the assistance of the gear 15, a knob 14 can drive multiple extrusion screws to rotate synchronously, thereby achieving efficient pushing of the atomized medium 1a to be formed in the accommodating chamber 111a. Multiple extrusion screws can increase the delivery rate of the atomized medium 1a to be formed, thereby improving efficiency without affecting the convenience of operation.

[0085] The number of extrusion screws can be two or more, and the number of gears 15 can be two or more; for example, see Figures 4 to 6 , the number of extrusion screws is 2, and the number of gears 15 is 3.

[0086] The specific structure of the atomizing assembly 12 is not limited.

[0087] In some embodiments, the atomization assembly 12 includes a heating element 121, which is used to atomize the medium segment 1b, and the heating element 121 surrounds the circumferential outer side of the medium segment 1b.

[0088] In this way, the aerosol generating matrix on the surface or inside of the medium segment 1b can be heated evenly, thereby improving the atomization consistency of the atomizer 1 and reducing the probability of affecting the user experience due to insufficient heating and atomization of the aerosol generating matrix on the surface or inside of the medium segment 1b or excessive heating to produce undesirable substances.

[0089] The heating element 121 can be fitted with the circumferential outer surface of the medium segment 1b, so that the heating element 121 and the medium segment 1b have a sufficiently large contact area, which is convenient for fully heating and atomizing the aerosol-generating matrix on the surface or inside of the medium segment 1b, improving the atomization reliability and enhancing the user experience.

[0090] It can be understood that in this embodiment, the heating element 121 surrounds the circumferential outer surface of the medium segment 1b, that is, the space surrounded by the heating element 121 is the atomization chamber 12a. Figures 1 to 6 In this embodiment, the shape of the heating element 121 is columnar.

[0091] Of course, in some other embodiments, the heating element 121 may not surround the circumferential outer side of the medium segment 1b, as long as it can atomize the medium segment 1b to generate aerosol, and there is no limitation here.

[0092] The shape of the heating element 121 may also be sheet-shaped, wire-shaped or other shapes.

[0093] For some examples, see Figures 1 to 6 The atomizing assembly 12 includes a coil 122 , which is wound around the outside of the heating element 121 and is used to generate a changing magnetic field so that the heating element 121 generates heat.

[0094] In this embodiment, the atomization component 12 uses induction heating to heat and atomize the medium segment 1b. The coil 122 can be connected to a power supply component, which provides current to the coil 122 to generate a changing magnetic field to heat the heating element 121, thereby heating and atomizing the medium segment 1b to generate an aerosol for the user.

[0095] In this embodiment, induction heating is adopted, the coil 122 has a fast heating speed, and the heating element 121 can be heated to the temperature required by the atomizing medium section 1b in a short time, thereby improving the atomization rate and shortening the atomization waiting time. In addition, the probability of deformation of the heating element 121 can be reduced, thereby extending the service life of the heating element 121.

[0096] Of course, the atomizer 1 can also use other heating methods to heat and atomize the medium segment 1b, such as resistance heating, infrared heating, laser heating, microwave heating, etc., which are not limited here.

[0097] The heating element 121 can be made of metal, which has a fast heating speed.

[0098] For some examples, see Figures 1 to 6 The forming channel 113a is coaxially arranged with the atomizing chamber 12a.

[0099] In this way, when the atomized medium 1a to be formed in the accommodating chamber 111a moves toward the atomizing chamber 12a after being formed through the forming channel 113a, it can smoothly enter the atomizing chamber 12a, reducing the probability of the formed medium segment 1b being obstructed when moving toward the atomizing chamber 12a, and there is no need to set up an additional guide channel in the atomizer 1. The formed medium segment 1b can move toward the atomizing chamber 12a more stably, thereby increasing the working reliability of the atomizer 1.
