[0033] The following describes the present disclosure m detail with reference to the accompanying drawings and embodiments.

[0034] Referring to FIG. 1 and FIG. 2, FIG. I is a schematic structural view after an atomization assembly and a power supply assembly are assembled according to an embodiment of the present disclosure. FIG. 2 is a schematic structural view after an atomization assembly and a power supply assembly are disassembled according to an embodiment of the present disclosure. In some embodiments, an aerosol-forming apparatus is provided. The aerosol-forming apparatus may heat and atomize aerosol-forming substrate when power is applied, so as to form an aerosol for inhaling by a user. In some embodiments, the aerosol-forming apparatus may be a smoking set, and the aerosol-forming substrate may be cannabis paste or oil.

[0035] In some embodiments, the aerosol-forming apparatus includes an atomization assembly 11 and a power supply assembly 12. The atomization assembly 11 is configured to heat and atomize aerosol-forming substrate 111 b when power is applied (see FIG. 5 and FIG. 6). The power supply assembly 12 is detachably connected to the atomization assembly 11, and is configured to supply power to the atomization assembly 11 after the atomization assembly 11 and the power supply assembly 12 are assembled. A product structure after the power supply assembly 12 and 5 CA 3203840 Date Reçue / Date Received 2023-06-29 the atomization assembly l l are assembled is shown in FIG. l. A product structure after disassembly is shown in FIG. 2. Because the power supply assembly 12 is detachably connected to the atomization assembly 11, when the atomization assembly 11 and the power supply assembly 12 are cleaned, the atomization assembly 11 and the power supply assembly 12 may be separated, thereby facilitating cleaning of the atomization assembly 11 and the power supply assembly 12.

[0036] Referring to FIG. 3 and FIG. 4, FIG. 3 is a schematic view of an overall structure of an atomization assembly according to an embodiment of the present disclosure. FIG. 4 is a schematic view of disassembling the structure shown in FIG. 3 according to an embodiment of the present disclosure. The atomization assembly 11 includes a liquid storage body 111 and a heating body 112. The liquid storage body 111 may be a tubular structure, and a liquid storage atomization cavity 111 a is formed on the surface of one side of the liquid storage body 111, in this way, the aerosolforming substrate 111 b may be stored in the liquid storage atomization cavity ll la. The heating body 112 may be a rod-shaped body and configured to heat and atomize the aerosol-forming substrate 111 b when power is applied.

[0037] In some embodiments, referring to FIG. 5 and FIG. 6, FIG. 5 is a schematic structural view of a heating body at a first location according to an embodiment of the present disclosure. FIG. 6 is a schematic structural view of a heating body at a second location according to an embodiment of the present disclosure. The heating body 112 is slidably connected to the liquid storage body 111 between a first location and a second location in the axial direction of the heating body 112. In addition, when the heating body 112 is located at the first location, the heating body 112 is located outside the aerosol-forming substrate 111 b. In this case, a specific location relationship between the heating body 112 and the liquid storage body 111 is shown in FIG. 5. In this case, a part of the heating body 112 is still located in the liquid storage atomization cavity 111 a, but does not contact the aerosol-forming substrate 111 b. When the heating body 112 is located at the second location, at least a part of the heating body 112 protrudes into the aerosolforming substrate 111 b. In this case, a specific location relationship between the heating body 112 and the liquid storage body l l l is shown in FIG. 6. In this way, the heating body 112 may protrude into the aerosol-forming substrate 111 b to heat the aerosol-forming substrate 111 b, or heat a small quantity of aerosol-forming substrate 111 b bonded to the heating body 112 outside the aerosolforming substrate 111 b, in this way, not only heating manners of the heating body 112 are increased, but also heating manners of the heating body 112 are diversified. In addition, in some embodiments, after the heating body 112 returns from the second location to the first location, a small quantity of aerosol-forming substrate 111 bis bonded to the part of the heating body I 12 that protrudes into the aerosol-forming substrate 11 lb. In this case, the heating body 112 only needs to heat and 6 CA 3203840 Date Reçue / Date Received 2023-06-29 atomize the small quantity of aerosol-forming substrate 11 lb. In comparison with a solution of protruding into the aerosol-forming substrate 111 b to atomize the aerosol-forming substrate 111 b, an amount of aerosol-forming substrate 111 b that needs to be heated and atomized each time is greatly reduced, in this way, atomization efficiency is effectively improved, an atomization time is shortened, a user may inhale a specific amount of aerosols each time, and a mouthfeel of the user is ensured.

[0038] In some embodiments, referring to FIG. l to FIG. 4, the atomization assembly 11 further includes a cover body 113. The cover body 113 may be disposed at the port of the liquid storage atomization cavity 111 a, to seal the liquid storage atomization cavity 111 a, so as to reduce the possibility of the aerosol generated by atomization leaking from the port of the liquid storage atomization cavity 111 a. In some embodiments, a through hole is formed in the cover body 113, and the through hole is in communication with the liquid storage atomization cavity 11 la. In some embodiments, the heating body 112 may include an extension part and a heating part that is axially connected to the extension part. The extension part is disposed in the through hole, and is slidably connected to the liquid storage body 111 through the through hole, which enables the heating part to disengage from or protrudes into the aerosol-forming substrate 111 b. The heating part is located in the liquid storage atomization cavity 111 a, and is configured to heat and atomize the aerosolforming substrate 111 b when power is applied.

[0039] In some embodiments, the through hole may be disposed at the central location of the cover body 113, and the part that is of the heating body 112 penetrating through the through hole and that is disposed in the liquid storage atomization cavity 111 a is disposed at an interval with the inner surface of the liquid storage atomization cavity 111 a. In comparison with a solution in which the heating body 112 abuts against the inner surface of the liquid storage atomization cavity 111 a, heat of the heating body 112 being conducted to the liquid storage body 111 may be reduced, a heat loss may be reduced, and the outer wall of the aerosol-forming apparatus may be ensured to be at a proper temperature for a human body. In addition, center heating may be implemented, and uniformity of heating may be improved.

[0040] In some embodiments, the surface of one side of the cover body 113 that faces the liquid storage body 111 further has a protrusion 114, the protrusion 114 may penetrate through the liquid storage atomization cavity I I la, and may interference fit with the inner surface of the liquid storage atomization cavity 111 a, so as to improve sealing performance of the liquid storage atomization cavity 11 la. In some embodiments, the protrusion 114 has a chute 114a that is in communication with the through hole. The part of the heating body 112 that protrudes into the liquid storage atomization cavity 111 a has a slider 112a. The slider 112a may move along the chute 7 CA 3203840 Date Reçue / Date Received 2023-06-29 114a, in this way, the heating body 112 is at the first location or the second location. The material of the cover body 113 and / or the protrusion 114 may be high-temperature-resistant metal, plastic, ceramic, or the like. (0041] Referring to FIG. 7 to FIG. 9, FIG. 7 is a schematic structural view in which a slider of a heating body protrudes into a chute according to an embodiment of the present disclosure; FIG. 8 is a schematic structural view in which a slider of a heating body is aligned with a chute according to an embodiment of the present disclosure; and FIG. 9 is a schematic structural view in which a slider of a heating body deviates from a chute according to an embodiment of the present disclosure. When the heating body 112 is at the first location, at least a part of the slider 112a is located in the chute 114a (refer to FIG. 7), and the vertical distance between the surface of one side of the slider 112a facing the cover body 113 and the surface of one side of the protrusion 114 that is away from the cover body 113 is less than or equal to the vertical distance between the first location of the heating body 112 and the second location of the heating body 112, in this way, when the heating body 112 is at the second location after the heating body 112 is depressed, the slider I 12a may fall off the limitation of the chute 114a, and the heating body 112 may be further rotated, in this way, the slider 112a may be aligned with or deviated from the chute 114a. A structure in which the slider 112a and the chute 114a are aligned is shown in FIG. 8. A specific structure in which the slider 112a and the chute 114a are deviated is shown in FIG. 9. When the heating body 112 is at the second location, the heating body 112 is rotatable and clamped to the side wall of the chute 114a by using the slider 112a, in this way, the heating body 112 may be fixed at a horizontal height of the second location, and at least a part of the heating body 112 is always located in the aerosolforming substrate 111 b, that is, at least a part of the heating body 112 is always in contact with the aerosol-forming substrate 111 b. In this way, the possibility that a user needs to press the heating body 112 each time during inhaling may be reduced, and an operation is relatively simple. In some embodiments, a heating solution in which the slider 112a is clamped on the side wall of the chute 114a is similar to that of a conventional Cannabis smoking set.

[0042] In some embodiments, a rotation angle may be l 0 degrees to 120 degrees.

[0043] The chute 114a may extend along the axial direction of the protrusion 114 from the surface of one side of the protrusion 114 facing the through hole to the surface of one side of the protrusion 114 away from the through hole, and the chute 114a may penetrate the side wall of the protrusion 114 along the radial direction of the protrusion 114. That is, the chute 114a may be a through groove in both the axial direction and the radial direction of the chute 114a. There may be two sliders 112a, and the two sliders 112a may be disposed opposite to each other on two sides of the heating body 112. In some embodiments, the slider 112a may be a rectangular block disposed 8 CA 3203840 Date Reçue / Date Received 2023-06-29 along the axial direction of the heating body 112, and the size of the rectangular block along the axial direction of the heating body 112 is greater than or equal to the size of the chute 114a along the axial direction of the heating body 112. The size of the rectangular block in the radial direction of the heating body 112 matches the radial sizes at corresponding locations of the chute 114a and the slider 112a, and the radial size at a corresponding location of the chute 114a for the heating body 112 matches the radial size of the heating body 112.

[0044] In some embodiments, an annular protrusion 112b is further disposed on the outer surface of the heating body 112. The annular protrusion 112b may be disposed on the end of the slider 112a that is away from the cover body 113, and may be integrally formed with the slider 112a. The annular protrusion 112b is configured to limit movement of the heating body 112 in the direction that faces the first location, so as to prevent the heating body 112 from falling from the liquid storage body 111.

[0045] In some embodiments, referring to FIG. 1 to FIG. 8, the atomization assembly 11 further includes an elastic member 115. The elastic member 115 is disposed along the axial direction of the heating body 112, and is configured to provide an acting force toward the first location to the heating body 112 when the heating body 112 is at the second location.

[0046] In some embodiments, the heating body 112 further includes a stop l 12c, the stop 112c extends along a periphery of the end of the extension part away from the heating part, that is, the stop 112c is disposed at the end of the extension part away from the heating part, and extends in the peripheral direction of the extension part. The radial size of the stop 112c is greater than the radial size of the extension part. In some embodiments, one end of the elastic member 115 abuts against the stop 112c of the heating body 112, and the other end abuts against the cover body 113. In addition, when the heating body 112 is at the first location, the elastic member 115 is in the naturally elongated state, and when the heating body 112 is at the second location, the elastic member I 15 is in the compressed state, so as to provide, by using the stop 112c, the heating body 112 with a driving force that moves toward the first location.

[0047] In some embodiments, the elastic member 115 may be a spring, and may be sleeved on the outer surface of the heating body 112.

[0048] In some embodiments, when the aerosol needs to be inhaled, the heating body 112 may be pressed by using an external force, in this way, the heating body 112 moves from the first location to the second location and contacts the aerosol-forming substrate 111 b (refer to FIG. 6). After the external force is removed, the heating body 112 moves to the first location under an elastic force generated by the elastic member 115 that restores a natural elongation state of the heating body 112 (refer to FIG. 5). In this case, a small quantity of aerosol-forming substrate 111 b 9 CA 3203840 Date Reçue / Date Received 2023-06-29 is bonded to the location at which the heating body 112 contacts the aerosol-forming substrate 111 b. The heating body 112 heats and atomizes the small quantity of aerosol-forming substrate 111 b, and may rapidly generate a large quantity of aerosols in 5-10 seconds, which effectively improves atomization efficiency. In addition, the user may control the quantity of press times according to the satisfaction of the user, and cultivate a personal inhalation habit.

[0049] In some embodiments, the atomization assembly 11 may further include a sealing member 116. The sealing member 116 may be sleeved on the outer surface of the liquid storage body 111, and wrap the surface of one side of the cover body I 13 that is away from the liquid storage body 111, so as to fix the cover body 113 and seal the connection location between the cover body 113 and the liquid storage body 111.

[0050] In some embodiments, referring to FIG. I and FIG. 2, the atomization assembly 11 further includes a cooling body 117. The cooling body 117 is detachably connected to and in communication with the liquid storage body 111, and is configured to cool the aerosol generated by the heating body 112 through atomization. In some embodiments, the cooling body 117 may be a water filter.

[0051] In some embodiments, the cooling body 117 may include a connecting part 117a and a cooling part 117b. The connecting part 117a is detachably connected to the liquid storage body 111, and is in communication with the liquid storage atomization cavity 111 a. The connecting part 117a may be detachably connected to the heating body 112 in a threaded or plugged manner. In this way, the liquid storage body 111 and the cooling body 117 may be quickly separated from each other, so as to facilitate cleaning inside the container. In some embodiments, the cooling part 117b is in communication with the connecting part 117a, and is configured to accommodate condensate 117c. In some embodiments, the aerosol generated by the heating body 112 through atomization enters, by using the connecting part 117a, the condensate 117c stored in the cooling part 117b, so as to cool the aerosol by using the condensate 117c, and filter out other impurities carried in the aerosol.

[0052] In some embodiments, the cooling part 117b may be integrally formed with the connecting part 117a. In addition, the connecting part 117a may be disposed at the middle location of the cooling part 1176.

[0053] The power supply assembly 12 may include a housing 121, a battery 122, a circuit board 123, and a coil 124. The battery 122 may be a lithium battery.

[0054] In some embodiments, the housing 121 has an accommodating cavity 121 a, and the battery 122 and the circuit board 123 may be accommodated in the accommodating cavity 121a. The circuit board 123 is connected to the battery 122, and the battery 122 is configured to provide IO CA 3203840 Date Reçue / Date Received 2023-06-29 power for the circuit board 123. The coil 124 is formed in the peripherical direction of the heating body 112, in electric communication with the circuit board 123, and is configured to generate a magnetic field when power is applied to heat the heating body 112 by means of electromagnetic induction. Because the heating body 112 is heated by means of electromagnetic induction, the aerosol-forming substrate I I lb may be quickly and evenly heated without contacting the coil 124. Compared with a solution in which an electrical connection manner is directly used, the noncontact heating by means of electromagnetic induction heating may disassemble the atomization assembly 11 and the power supply assembly 12 at any time, and the disassembly is relatively convenient.

[0055] In some embodiments, a first recession part 121 bis formed on the surface of one side of the housing 121, and the coil 124 is disposed on the inner surface of the first recession part 121 b along the peripherical direction of the first recession part 121 b.
