Convection evaporators have a cavity that contains an aerosol-generating matrix. Convection evaporators can preheat the air before entering the cavity, and then heat and evaporate the aerosol-generating matrix to produce an aerosol for users to take. The aerosol produced by the convection evaporator has a good taste, so it is popular with users. However, due to structural defects, the existing convection evaporators still have the problem of uneven heating, which hinders the further improvement of the taste of the aerosol.

[0036] One embodiment of the present application provides a evaporation device (not shown), which refers to a device that interacts with an aerosol generating substrate to generate an aerosol, and the aerosol can be absorbed by the user in some form. In some embodiments, the aerosol generating device can heat the aerosol generating substrate to promote the release of volatile compounds. The heating device can be an electric heating element, an electromagnetic receptor element, a light wave heater, or an ultrasonic device. The evaporation device can interact with an aerosol generating product including an aerosol generating substrate or a storage device including an aerosol generating substrate, for example, by heating the substrate or product through the device. The aerosol substrate can be in a solid, liquid, or paste-like form.

[0037] 1 to 3 , the evaporation device includes an evaporator 100 and a battery assembly (not shown). The battery assembly is connected to the evaporator 100 to power the evaporator 100 . The evaporator 100 can heat the evaporated aerosol generating substrate to generate aerosol under the action of the electric energy of the battery assembly.

[0038] Specifically, the evaporator 100 includes an insulating outer shell 10, an insulating base 20, a separation component 30, a heating component 40 and an exhaust component 50 that are matched with each other. The insulating outer shell 10 and the insulating base 20 are matched with each other to play the role of support, fixation and protection. The heating component 40 includes a heating element 45 and has a accommodating chamber 41a for storing an aerosol generating matrix. The separation component 30 is matched with the heating component 40 and connected to the accommodating chamber 41a. The exhaust component 50 is matched with the separation component 30, and the exhaust component 50 is provided with an exhaust channel 52a connected to the accommodating chamber 41a. Among them, when the heating element 45 heats the aerosol generating matrix, the separation component 30 changes the direction of the airflow so that the aerosol generated by the heated aerosol generating matrix in the accommodating chamber 41a is discharged through the exhaust channel 52a.

[0039] When the user inhales the vaporizer 100, the airflow can flow into the receiving chamber 41a through the separation component 30, and the aerosol carrying the effective substance in the aerosol generating matrix in the receiving chamber 41a flows out through the exhaust passage 52a for the user to take. Since the separation component 30 changes the direction of the airflow movement so that the aerosol generated by heating the aerosol generating matrix in the receiving chamber 41a is discharged through the exhaust passage 52a, the temperature field in the receiving chamber 41a is made more uniform, and the aerosol generating matrix in the receiving chamber 41a is evenly heated, and finally the taste of the aerosol flowing out of the exhaust passage 52a is improved.

[0040] Please continue to refer to Figures 1 to 3. The heat insulating shell 10 is a hollow shell structure with two ends open. In the following embodiments, the extension direction of the central axis of the heat insulating shell 10 is defined as the first direction (ie, the Z direction in Figures 1 and 2).

[0041] The heat-insulating base 20 is a rotating body structure, and the heat-insulating base 20 is matched with an open end of the heat-insulating shell 10. Two connecting electrodes 21, one positive and one negative, are inserted into the heat-insulating base 20, and the two connecting electrodes 21 are arranged at intervals in a radial direction of the heat-insulating base 20. The battery assembly is electrically connected to the evaporator 100 through the connecting electrodes 21. As a preferred embodiment, the evaporator 100 also includes at least one base sealing ring, which is sleeved on the outer periphery of the heat-insulating base 20, so that the heat-insulating base 20 is sealed and connected to the heat-insulating shell 10.

[0042] The exhaust assembly 50 is coupled to the other open end of the heat-insulating housing 10 away from the heat-insulating base 20. An exhaust passage 52a connected to the outside atmosphere is formed in the exhaust assembly 50, and the central axis of the exhaust passage 52a coincides with the central axis of the heat-insulating housing 10. Specifically, the exhaust assembly 50 includes an exhaust pipe 52 and a suction nozzle 54. The exhaust pipe 52 is generally a hollow columnar structure. One end of the exhaust pipe 52 is coupled to the heat-insulating housing 10 by means of threaded connection, and the other end of the exhaust pipe 52 extends in a first direction away from the heat-insulating housing 10. The suction nozzle 54 is a hollow cylindrical structure. The suction nozzle 54 is sealed and coupled to the end of the exhaust pipe 52 away from the heat-insulating housing 10 through a sealing ring, so that the user can inhale the aerosol in the exhaust passage 52a.

[0043] As a preferred embodiment, at least one heat dissipation fin 56 is convexly provided on the outer surface of the side wall of the exhaust pipe 52 (i.e., the outer surface of the channel wall of the exhaust channel 52a). The provision of the heat dissipation fin 56 increases the heat dissipation area of ​​the exhaust pipe 52, thereby reducing the temperature of the aerosol in the exhaust channel 52a. Specifically, in some embodiments, a plurality of heat dissipation fins 56 are convexly provided on the outer surface of the side wall of the exhaust pipe 52, all heat dissipation fins 56 are arranged at intervals along the extension direction of the exhaust pipe 52, and each heat dissipation fin 56 is in a circular ring shape to surround the exhaust pipe 52 in the circumferential direction. It can be understood that the number, shape and arrangement of the heat dissipation fins 56 are not limited thereto, and can be arranged as needed to achieve different heat dissipation effects. It can be understood that the heat dissipation method of the exhaust assembly 50 is not limited thereto. In some other embodiments, phase change heat dissipation, water cooling heat dissipation and other methods can also be used to reduce the temperature of the aerosol in the exhaust channel 52a, which is not limited here.

[0044] It should be noted that “from bottom to top” described in the following embodiments refers to the direction from the insulation base 20 along the first direction pointing to the exhaust assembly 50, that is, the direction indicated by the Z-axis arrow in FIG. 1 .

[0045] Please continue to refer to Figures 2 and 3. The separation component 30 and the heating component 40 are connected to each other and accommodated in the insulating shell 10. The separation component 30 includes a separation base 32 and a cyclone separator 34. The cyclone separator 34 is used to form a separation channel 343a. The heating component 40 is connected between the separation base 32 and the cyclone separator 34 to form a accommodating chamber 41a.

[0046] The separation base 32 is a body of revolution structure, and the separation base 32 is coupled to the side of the heat insulation base 20 facing the exhaust assembly 50, and the central axis of the separation base 32 coincides with the central axis of the heat insulation shell 10. The side of the separation base 32 facing the exhaust assembly 50 is formed with a mounting groove 32a at the center and a connecting groove 32b surrounding the mounting groove 32a in the circumferential direction.

[0047] Please refer to FIG. 2 , FIG. 4 and FIG. 5 , the heating assembly 40 is connected to a side of the separation base 32 away from the insulation base 20 , and includes a heating body 41 , a mounting bracket 43 and a heating element 45 .

[0048] The heating body 41 is a hollow rotating body structure with two ends open. The heating body 41 is connected to the separation base 32. The heating body 41 is connected to the installation groove 32a of the separation base 32 to form a receiving chamber 41a, and the central axis of the receiving chamber 41a coincides with the central axis of the heat-insulating shell 10. The side wall of the heating body 41 is provided with at least one heating channel 41b. Each heating channel 41b is located on one side of the radial direction of the receiving chamber 41a and is arranged corresponding to the connecting groove 32b of the separation base 32. Each heating channel 41b is used to connect the separation channel 343a with the external atmosphere. The heating element 45 is accommodated in the heating channel 41b. The heating element 45 can pass through the connecting groove 32b of the separation base 32 to be electrically connected to the connecting electrode 21 in the heat-insulating base 20, so as to generate heat under the action of the electric energy of the battery assembly to heat up the air in the heating channel 41b.

[0049] As a preferred embodiment, the heating body 41 is provided with a plurality of heating channels 41b, all of which are evenly spaced and arranged outside the accommodating cavity 41a along the circumference of the accommodating cavity 41a, and each heating channel 41b extends along the axial direction of the accommodating cavity 41a to penetrate the opposite end faces of the heating body 41. The heating assembly 40 includes a plurality of heating elements 45, each of which is correspondingly accommodated in a heating channel 41b, and the heating element is a heating wire that spirally extends along the first direction, and each heating element 45 can be connected in series or in parallel according to the required power.

[0050] The mounting bracket 43 is a hollow cylindrical structure with two ends open. The mounting bracket 43 is sleeved outside the heating body 41, and the central axis of the mounting bracket 43 coincides with the central axis of the heating body 41. The outer surface of the side wall of the heating body 41 is provided with a plurality of grooves, and all the grooves are arranged at intervals along the circumference of the heating body 41. Each groove extends from one end of the heating body 41 away from the separation base 32 to the end surface of the heating body 41 connected to the separation base 32, so that a plurality of air inlet channels 41c are formed between the heating body 41 and the mounting bracket 43. The end of the mounting bracket 43 away from the separation base 32 is provided with a plurality of groups of air inlet holes 43a connected to the external atmosphere, and each group of air inlet holes 43a includes at least one air inlet hole 43a, and each group of air inlet holes 43a is correspondingly connected to an air inlet channel 41c. A plurality of air inlet grooves 10a are correspondingly provided on the heat-insulating shell 10, and each air inlet groove 10a is correspondingly connected to one group of air inlet holes 43a.

[0051] In this way, the air in the external environment can flow into the air intake channel 41c through the air intake groove 10a and the air intake hole 43a in turn, and then flow toward the separation base 32 along the axial direction of the accommodating cavity 41a in the air intake channel 41c and enter the connecting groove 32b of the separation base 32, and then reversely enter the heating channel 41b. The heating element 45 in the heating channel 41b can heat the airflow flowing through the heating channel 41b.

[0052] Further, in some embodiments, the heat-insulating shell 10 is sleeved outside the mounting bracket 43, and an assembly gap is reserved between the mounting bracket 43 and the heat-insulating shell 10 to form a heat-insulating gap, the heat-insulating gap surrounds the outside of the accommodating cavity 41a along the circumferential direction, and the heating channel 41b is located between the accommodating cavity 41a and the heat-insulating gap, and the air layer in the heat-insulating gap can play a role in heat insulation. In some other embodiments, heat-insulating materials such as heat-insulating cotton can also be filled in the heat-insulating gap, which can also play a role in heat insulation.

[0053] Please refer to FIG. 2 and FIG. 3 again. The cyclone separation member 34 is connected to the end of the heating body 41 facing away from the separation base 32, and includes a central tube 341 and a cyclone separation shell 343 surrounding the central tube 341 in the circumferential direction. One end of the cyclone separation shell 343 is inserted into the end of the heating body 41 away from the separation base 32, and the other end of the cyclone separation shell 343 extends out of the heating body 41. One end of the central tube 341 is located in the cyclone separation shell 343, and the other end of the central tube 341 extends out of the cyclone separation shell 343 in the direction away from the separation base 32 and is inserted into the exhaust pipe 52 of the exhaust assembly 50.

[0054] Furthermore, in some embodiments, the separation assembly 30 further includes a filter 36, which is a hollow cylindrical structure, and is accommodated in the cyclone separation housing 343. One end of the filter 36 is sealed, and the other end of the filter 36 is open and inserted into one end of the central tube 341 facing the separation base 32. At least one filter hole 36a is provided on the side wall of the filter 36. As a preferred embodiment, the filter 36 is provided with a plurality of filter holes 36a, and all the filter holes 36a are arranged at intervals on the side wall of the filter 36.

[0055] In this way, a separation channel 343a spirally extending around the central axis of the accommodating chamber 41a is formed in the cyclone separation housing 343, the inlet end of the separation channel 343a is axially close to the exhaust assembly 50 and along the axial direction perpendicular to the central tube 341, and the outlet end of the separation channel 343a is connected to the accommodating chamber 41a in the heating body 41. The filter element 36, the central tube 341 and the exhaust assembly 50 jointly form an exhaust channel 52a extending along the axial direction of the accommodating chamber 41a, one end of the exhaust channel 52a is located in the separation channel 343a and faces the accommodating chamber 41a, and the other end of the exhaust channel 52a is connected to the external atmosphere.

[0056] The hot air flow out of the heating channel 41b first enters the separation channel 343a, and under the action of the separation channel 343a, the airflow spirally flows downward and enters the accommodating chamber 41a, and after reaching the end of the accommodating chamber 41a close to the separation base 32, it flows toward the cyclone separator 34 along the first direction, and finally enters the exhaust channel 52a through the filter hole 36a. Since the airflow rotates and flows in the accommodating chamber 41a under the action of the separation channel 343a, the fragments of the aerosol generating matrix move along the cavity wall of the accommodating chamber 41a driven by the airflow, thereby significantly reducing the risk of the fragments clogging the filter 36.

[0057] In some embodiments, the evaporator 100 further includes a accommodating unit 60, which is accommodated in the accommodating cavity 41a, and a accommodating cavity for accommodating the aerosol generating substrate is provided in the accommodating unit 60. Specifically, the accommodating unit 60 is a hollow cylindrical structure, including a cover body 63 and an accommodating body 61 with an opening at one end, and the cover body 63 is detachably covered on the open end of the accommodating body 61. A plurality of connecting holes 60a are provided on the bottom wall edge of the end of the accommodating body 61 away from the cover body 63, the side wall and the cover body 63, and each connecting hole 60a connects the accommodating cavity with the accommodating cavity 41a respectively.

[0058] In this way, the airflow in the accommodating chamber 41a can flow into the accommodating unit 60 through the connecting hole 60a, and then flow out with the effective substance generated by the aerosol generating substrate being heated and atomized. Since the aerosol generating substrate is accommodated in the accommodating unit 60, the aerosol generating substrate will not directly contact the cavity wall of the accommodating chamber 41a, so there is no problem that the accommodating chamber 41a is difficult to clean.

[0059] Furthermore, in some embodiments, the accommodating unit 60 can be rotatably limited in the accommodating chamber 41a, and the rotation axis of the accommodating unit 60 coincides with the central axis of the accommodating chamber 41a. The accommodating unit 60 can rotate around its rotation center, so that the aerosol generating matrix therein moves from the center to the outside under the action of centrifugation, and at the same time, under the action of the airflow moving axially from bottom to top (i.e., from the separation base 32 to the direction of the cyclone separator 34), the aerosol generating matrix will be continuously stirred in the accommodating unit 60, so that the aerosol generating matrix is ​​heated more evenly, and then the extraction of effective substances is more sufficient, which effectively reduces the problem of the aerosol generating matrix changing taste due to local high temperature or insufficient extraction due to local low temperature.

[0060] Specifically, in one embodiment, the evaporator 100 includes a rotating member 70, which is rotatably mounted in the mounting groove 32a of the separation base 32, and the central axis of the rotating member 70 coincides with the central axis of the accommodating chamber 41a. Driven by the rotating airflow in the accommodating chamber 41a, the rotating member 70 can rotate around its own central axis, and one end of the accommodating unit 60 is connected to the rotating member 70, so that it can rotate synchronously with the rotating member 70. As a preferred embodiment, the rotating member 70 is an impeller, and the impeller is rotatably limited in the mounting groove 32a of the separation base 32 through a bearing.

[0061] In some embodiments, the rotating member 70 and the accommodating unit 60 can attract each other under the action of a magnetic field. Specifically, a magnetic member 90 is embedded in the center of one end of the rotating member 70, and the accommodating unit 60 is formed of a ferromagnetic material, so the accommodating unit 60 can be attracted by the magnetic member 90 and connected to the rotating member 70. When the aerosol generating matrix is ​​used up, the heat insulating base 20, the separation base 32, the rotating member 70 and the accommodating unit 60 can be separated from the heat insulating housing 10, so that the accommodating unit 60 can be easily separated from the rotating member 70 to achieve the replacement of the accommodating unit 60. In this way, the user can carry multiple accommodating units 60 for replacement. In some other embodiments, the accommodating unit 60 can be reused to cyclically load new aerosol generating matrix.

[0062] Furthermore, the evaporator 100 further includes a stopper 80, which is matched to one end of the exhaust passage 52a close to the accommodating chamber 41a, and one end of the accommodating unit 60 away from the rotating member 70 is abutted against the stopper 80. In this way, the accommodating unit 60 is rotatably limited in the accommodating chamber 41a by the rotating member 70 and the stopper 80, and the accommodating unit 60 can rotate under the drive of the rotating member 70. The stopper 80 can ensure the coaxiality of the accommodating unit 60 and the rotating member 70, so that the rotation of the accommodating unit 60 is more stable and reliable. As a preferred embodiment, the stopper 80 can be extended and retracted in the first direction, so as to facilitate the disassembly and assembly of the accommodating unit 60.

[0063] 2 and 3 , the working principle of the evaporator 100 is as follows:

[0064] The external atmosphere enters the plurality of heating channels 41b through the air inlet groove 10a of the heat-insulating housing 10, the air inlet hole 43a on the mounting bracket 43, and the air inlet channel 41c between the mounting bracket 43 and the main body. The heating element 45 in the heating channel 41b is electrically connected to the battery assembly through the connecting electrode 21, and the heating element 45 generates heat under the action of the electric energy of the battery assembly to preheat the air in the heating channel 41b.

[0065] After preheating, the user inhales through the mouthpiece 54, and the high-temperature airflow in the heating channel 41b enters the accommodating chamber 41a through the separation channel 343a. The airflow entering the accommodating chamber 41a rotates from top to bottom under the action of the separation channel 343a to the bottom of the accommodating chamber 41a, and then enters the accommodating unit 60 from the bottom of the accommodating unit 60 and flows from bottom to top, thereby extracting the effective substance in the aerosol generating matrix. The airflow containing the effective substance flows out of the accommodating unit 60, flows into the exhaust channel 52a through the filter element 36, and finally enters the user's mouth.

[0066] The above-mentioned evaporator 100 forms a uniform heat field to heat the aerosol generating substrate through the setting of the separation channel 343a, so that the mouthfeel of the aerosol generated by the heated aerosol generating substrate has a high consistency. Moreover, the user's inhalation can cause the accommodating unit 60 to rotate at a high speed, so that the aerosol generating substrate in the accommodating unit 60 is heated and extracted evenly, further improving the mouthfeel of the generated aerosol. Moreover, the aerosol generating substrate is accommodated in the accommodating unit 60, so it is easy to replace and clean.

[0067] The technical features of the above-described embodiments may be arbitrarily combined.
