[0002] The present invention claims priority to Chinese patent application 2021214822331 filed on June 30, 2021, the contents of which are incorporated herein by reference.

[0003] The present invention relates to the field of spray equipment technology, and in particular to an aerosol forming device. Background Technology

[0004] Heat Not Burning (HNB) equipment combines a heating device with an aerosol-generating substrate (e.g., processed tobacco products). The external heating device heats the aerosol-generating substrate to a high temperature (200–350°C) where aerosols can be generated but combustion does not occur. Under the premise that the aerosol-generating substrate does not burn, it can emit aerosol fragrances. When ignited and smoked, the temperature reaches between 350 and 600°C; at this temperature range, combustion generates a large amount of harmful substances, including carbon monoxide, alkaloids such as nicotine, amines, nitriles, alcohols, phenols, alkanes, aldehydes, and nitrogen oxides. However, the heat not burning method operates at a temperature of around 300°C, which does not generate flames, significantly reducing harmful substances. For example, HNB adopts a low-temperature baking method for heating instead of the traditional method of directly burning tobacco, and it is gaining increasing interest from smokers worldwide, presenting a new direction for the upgrading of the global tobacco industry.

[0027] In this embodiment, an aerosol forming device (10) is provided as shown in FIG. 1, and the aerosol forming device (10) includes a main body (11), a heating assembly (12), and a fixing assembly (13).

[0028] Here, as illustrated in FIGS. 2 and FIGS. 3a, the main body (11) may include a housing (111) and an inner sheet (112); wherein the inner sheet (112) is installed within the housing (111) and a receiving groove (1120) is installed, and at least a portion of the heating assembly (12) is received within the receiving groove (1120) and electrically connected to the main body (11). Specifically, the main body (11) further includes a power supply assembly installed within the housing (111), and when the heating assembly (12) is received within the receiving groove (1120), the heating assembly (12) is connected to the power supply assembly of the main body (11) to supply power to the heating assembly (12) through the power supply assembly. Specifically, the electrical connection method between the heating assembly (12) and the main body (11) is a pogo pin contact type connection. Here, the main body (11) may specifically be columnar, and the cross-section of the main body (11) may be circular, elliptical, or polygonal.

[0029] A heating assembly (12) heats and atomizes an aerosol generating substrate when power is supplied; specifically, referring to FIGS. 2 and FIGS. 3a, the heating assembly (12) may include a fixed sheet (121) and a heating element (122); wherein at least a portion of the fixed sheet (121) is received within a receiving groove (1120); and the heating element (122) is installed in the fixed sheet (121), and when the fixed sheet (121) is received within the receiving groove (1120), the heating element (122) is electrically connected to the power supply assembly of the main body (11) so that the aerosol generating substrate is heated and atomized after power is supplied to the heating element (122). In one specific embodiment, a power interface is installed on the bottom wall of the receiving groove (1120), and one end of the heating element (122) extends to one side surface of the fixed sheet (121) facing the bottom wall of the receiving groove (1120). When the fixed sheet (121) is received within the receiving groove (1120), the one end of the heating element (122) comes into contact with the power interface to establish an electrical connection with the power supply assembly through the power interface.

[0030] In one specific embodiment, referring to FIG. 3a or FIG. 7, the fixed sheet (121) may specifically include a fixed base (1211) and a limit portion (1212) installed along the circumferential direction of the fixed base (1211).

[0031] Here, the fixed base (1211) may be cylindrical; at least a portion of the fixed base (1211) may be received within the receiving groove (1120), and the heating element (122) is specifically fixed on the fixed base (1211). Specifically, to prevent the fixed base (1211) from shaking within the receiving groove (1120) and causing a problem of poor contact between the heating element (122) and the power supply assembly; the outer diameter of the fixed base (1211) is made to match the diameter of the receiving groove (1120), that is, the diameter of the receiving groove (1120) is the same as the outer diameter of the fixed base (1211), or the receiving groove (1120) and the fixed base (1211) are made to be press-fitted so that the heating element (122) is in close contact with the interface of the power supply assembly, thereby ensuring that the heating element (122) can be effectively connected to the power supply assembly.

[0032] The limit portion (1212) may specifically be an annular flange installed on the outer wall of the fixed base (1211) and may be installed around the circumferential direction of the fixed base (1211); the limit portion (1212) may specifically be located at one end of the fixed base (1211) close to the heating element (122), and the outer diameter of the limit portion (1212) is made larger than the diameter of the receiving groove (1120) so that after the heating element (122) is connected to the power supply assembly, the limit portion (1212) comes into contact with the cross-section of the inner sheet (112), that is, it comes into contact with the cross-section of the end where the notch of the receiving groove (1120) is located. Here, the outer diameter of the limit portion (1212) specifically refers to the diameter of the shape corresponding to the outer surface of the limit portion (1212).

[0033] In one specific embodiment, with reference to FIG. 6, the outer diameter of the limit portion (1212) is made to match the inner diameter of the housing (111), that is, the outer diameter of the limit portion (1212) is the same as the inner diameter of the housing (111), or the limit portion (1212) and the housing (111) are made to be forced-fitted, thereby limiting the position of the limit portion (1212) in the radial direction of the limit portion (1212) using the inner wall of the housing (111), so that the heating assembly (12) can be prevented from shaking along the direction of movement.

[0034] Referring to FIG. 2 or FIG. 5, a fixed assembly (13) is detachably connected to a main body (11), and when the fixed assembly (13) is connected to the main body (11), the fixed assembly (13) contacts at least a part of the heating assembly (12) to fix the heating assembly (12) within the receiving groove (1120) of the main body (11). In one preferred embodiment, the fixed assembly (13) contacts at least a part of the heating assembly (12) to enhance the fixing effect. Specifically, the fixed assembly (13) may contact the limit portion (1212) of the fixed sheet (121); and the fixed connection between the heating assembly (12) and the main body (11) may be realized solely by the fixed assembly (13). Here, the heating assembly (12) is fixed within the receiving groove (1120) of the main body (11) through the fixed assembly (13), and the fixed assembly (13) is detachably connected to the main body (11). Therefore, when replacing or cleaning the heating assembly (12), the heating assembly (12) and the main body (11) can be separated simply by detaching the fixed assembly (13). After replacement or cleaning is completed, the heating assembly (12) can be re-fixed to the main body (11) simply by reconnecting the fixed assembly (13) to the main body (11). Thus, replacing and cleaning the heating assembly (12) becomes more convenient compared to a method of fixedly connecting the heating assembly (12) and the main body (11).

[0035] In one specific embodiment, referring to FIG. 6, the fixed assembly (13) may specifically be a hollow tubular body, and the diameter of the hollow tubular body is smaller than the outer diameter of the limit part (1212), and the diameter of the hollow tubular body is also smaller than the diameter of the receiving groove (1120), so that the heating assembly (12) can be fixed to the main body (11) by contacting the limit part (1212) through the side wall of the hollow tubular body.

[0036] In another specific embodiment, referring to FIG. 3a or FIG. 7, the fixed assembly (13) may include a fixed body (131) and a first pressurizing part (132) installed on the fixed body (131); wherein the fixed body (131) may be a hollow tubular body, and the fixed body (131) forms a receiving cavity (1310) for receiving an aerosol generating substrate; and the first pressurizing part (132) may specifically be installed on the inner wall surface of the tubular fixed body (131). In a specific embodiment, the first pressurizing part (132) of the fixed assembly (13) contacts a limit part (1212) of the heating assembly (12), and fastens the limit part (1212) between the first pressurizing part (132) and the side wall of the inner sheet (112) to fix the heating assembly (12) to the main body (11); The heating element (122) extends through the first pressurizing part (132) into the receiving cavity (1310) and can heat and atomize the aerosol generating substrate after power supply.

[0037] Specifically, the fixed body (131) may be a tubular body with both ends open, and the cross-section of the fixed body (131) may specifically be circular or polygonal. Referring to FIG. 3a or FIG. 7, the first pressing part (132) may be installed at the end of the tubular body connected to one end of the main body (11) and located within the tubular body. In a specific embodiment, the fixed body (131) and the first pressing part (132) may be formed integrally.

[0038] Specifically, referring to FIG. 3a, FIG. 7, or FIG. 8, a single through hole (1320) may be formed in the first pressurizing part (132), and when the first pressurizing part (132) comes into contact with the fixed sheet (121), the part of the heating element (122) protruding from the fixed sheet (121) extends into the receiving cavity (1310) through the through hole (1320), thereby allowing the heating element (122) to avoid the first pressurizing part (132) and heat the aerosol generating substrate inserted into the receiving cavity (1310), making it convenient to clean the heating element (122). In one specific embodiment, the shape and diameter of the through hole (1320) are made to match the shape and outer diameter of the heating element (122), that is, the diameter of the through hole (1320) is the same as the outer diameter of the heating element (122), or the through hole (1320) and the heating element (122) are made to be forcibly fitted together, thereby scraping off residue attached to the heating element (122) using the side wall of the through hole (1320), i.e., the first pressure part (132), and by limiting the position of the heating element (122) in the radial direction through the first pressure part (132), the heating assembly (12) can be prevented from shaking along the radial direction. In addition, the central axis of the through hole (1320) is aligned with the central axis of the tubular fixed assembly (13), that is, by making it a common line, the distance between the heating element (122) and the inner wall of the fixed assembly (13) is the same in all directions, and even if the heating element (122) is at the center position of the fixed assembly (13), the heating element (122) can heat the center of the aerosol generating substrate inserted into the fixed assembly (13), thereby improving the uniformity of heating.

[0039] Of course, in other embodiments, with reference to FIG. 3b, the diameter of the through hole (1320) may be larger than the radial size of the heating element (122); in this embodiment, the shape of the through hole (1320) may match the outer contour of the fixed base (1211), and the diameter of the through hole (1320) may match the outer diameter of the fixed base (1211), that is, the diameter of the through hole (1320) may be the same as the outer diameter of the fixed base (1211), or the through hole (1320) and the fixed base (1211) may be made to be a press fit. The limit portion (1212) is located at one end of the fixed base (1211) near the first pressure portion (132), and the straight distance (L) between the cross-section (S) of the fixed base (1211) near the first pressure portion (132) and the limit portion (1212) is equal to the thickness (H) of the first pressure portion (132). Thus, the fixed base (1211) is inserted and installed within a through hole (1320) formed by the first pressure portion (132) in which the portion located on one side of the limit portion (1212) near the first pressure portion (132) is limited by the first pressure portion (132), thereby limiting the position of the fixed base (1211) in the radial direction through the first pressure portion (132), thereby preventing the heating assembly (12) from shaking back and forth along the radial direction.

[0040] Here, the first pressurizing part (132) may specifically be a projection installed on the inner wall of the tubular body; in one specific embodiment, referring to FIG. 3a or FIG. 7, the projection may be an annular flange, and the annular flange is installed around the circumferential direction of the tubular body. Of course, in other embodiments, the projection may include a plurality of bumps, and the plurality of bumps are installed spaced apart along the circumferential direction of the tubular body, and one end of the plurality of bumps far from the inner wall surface of the tubular body forms a through hole (1320) for passing a heating element (122) on the heating assembly (12); preferably, the plurality of bumps are installed at equal intervals along the circumferential direction of the tubular body.

[0041] Referring to FIG. 8, in one embodiment, the fixed assembly (13) may further include a second pressure member (133); the second pressure member (133) is connected to the fixed body (131) and extends in a direction away from the fixed body (131) along the longitudinal direction of the fixed body (131), thereby limiting the position of the heating assembly (12) in the radial direction of the fixed sheet (121). Specifically, the second pressure part (133) is tubular, and the diameter of the tubular second pressure part (133) is made to match the outer diameter of the limit part (1212), so that the outer diameter of the limit part (1212) is the same as the diameter of the second pressure part (133), or so that the limit part (1212) and the second pressure part (133) are forcibly fitted together, thereby limiting the position of the limit part (1212) in the radial direction of the limit part (1212) and fixing the heating assembly (12) in the radial direction of the heating assembly (12).

[0042] Specifically, referring to FIG. 8, in the above embodiment, a stopper (1121) is also formed on the outer wall of one end of the inner sheet (112) far from the first pressure part (132) and the second pressure part (133), and after the first pressure part (132) and the second pressure part (133) are connected to the main body (11), one end of the second pressure part (133) far from the fixed body (131) comes into contact with the stopper (1121).

[0043] In one embodiment, referring to FIGS. 2 and FIGS. 3a, the fixed assembly (13) and the main body (11) can specifically implement a detachable connection through a screw thread.

[0044] Specifically, a first tubular connection is formed at one end of a fixed assembly (13) facing the main body (11); a second tubular connection is formed at one end of the main body (11) facing the fixed assembly (13), and a male screw thread is formed on the outer wall of one of the first tubular connection of the fixed assembly (13) and the second tubular connection of the main body (11), and a female screw thread is formed on the inner wall of the other, thereby realizing a screw thread connection between the two through the tightening of the male screw thread and the female screw thread.

[0045] In one specific embodiment, referring to FIG. 3a, the housing (111) includes a first housing part (1112) and a second housing part (1113) connected in the axial direction; the first housing part (1112) forms a second tubular connection part of the main body (11), and the male screw thread is specifically formed on the outer wall of the first housing part (1112) and the female screw thread is specifically formed on the inner wall of the first tubular connection part; specifically, the female screw thread is formed on the inner wall of the second pressure part (133).

[0046] Here, after the fixed assembly (13) and the main body (11) are tightened together, the outer diameters of the two are made to match, that is, the outer diameter of the fixed assembly (13) is the same as the outer diameter of the main body (11), or the fixed assembly (13) and the main body (11) are made to be forced-fitted, thereby improving the overall harmony of the product and the overall aesthetics of the product. The outer diameter of the first housing part (1112) is smaller than the outer diameter of the second housing part (1113), and the difference between the outer diameter of the first housing part (1112) and the outer diameter of the second housing part (1113) can be equal to the wall thickness of the pipe wall of the fixed assembly (13).

[0047] Referring to FIGS. 4 to 7, in this embodiment, the fixed assembly (13) and the main body (11) specifically implement a detachable connection through a buckle (134).

[0048] Specifically, a buckle (134) is formed in one of the first tubular connecting part of the fixed assembly (13) and the second tubular connecting part of the main body (11), and a locking groove (1111) is formed in the other, thereby enabling the connection of the two buckles (134).

[0049] In one embodiment, a buckle (134) may be formed in a first tubular connection of a fixed assembly (13) and may be located on the outer wall surface of the first tubular connection; a catch groove (1111) may be formed in a second tubular connection of a main body (11), and the catch groove (1111) may specifically include a guide groove (111a) and a snap groove (111b) that are in communication with each other; wherein, the guide groove (111a) specifically extends from a cross-section of one end of the main body (11) facing the fixed assembly (13) toward an end far from the fixed assembly (13), that is, the guide groove (111a) is an open groove, and the open groove allows the buckle (134) on the first tubular connection to enter the guide groove (111a) toward the first tubular connection; The snap groove (111b) extends along the circumferential direction of the main body (11), and after the buckle (134) enters the guide groove (111a), it moves along the guide groove (111a) to a position communicating with the snap groove (111b), and then the first tubular connecting part and the second tubular connecting part move relative to each other in the radial direction so that the buckle (134) slides into the snap groove (111b), thereby realizing the buckle (134) connection between the fixed assembly (13) and the main body (11).

[0050] In one specific embodiment, referring to FIG. 7, the fixed body (131) may include a first body part (131a) and a second body part (131b); wherein the outer diameter of the first body part (131a) is larger than the outer diameter of the second body part (131b), and the outer diameter of the first body part (131a) may be the same as the outer diameter of the main body (11); A first tubular connection is formed in the second body part (131b), and a buckle (134) is specifically formed on the outer surface of the second body part (131b).
