[0024] FIG. 1 to FIG. 3 show an electronic atomization device 1 according to some embodiments of the present disclosure. The electronic atomization device 1 may be substantially in the shape of a round cylinder, and may include a main unit 200 and an atomizer 100 arranged above the main unit 200 along the longitudinal direction.

[0025] The main unit 200 is mainly configured to supply power to the atomizer 100, and may control turn-on and turn-off of the entire electronic atomization device. The atomizer 100 is configured to accommodate an aerosol-forming substance, and to heat and atomize the aerosol- forming substance after being electrified, so as to generate an aerosol to be inhaled by a user. The aerosol-forming substance may be in a form of a plant leave, a paste, a gel, or the like.

[0026] It may be understood that in other embodiments, the shape of the electronic atomization device 1 is not limited to the shape of a round cylinder, but may also be other shapes such as the shape of an elliptical cylinder, the shape of a square cylinder, the shape of a flat cylinder, or the like.

[0027] In some embodiments, the main unit 200 may include a shell 40, a battery 50, a circuit board 60, a holder 70, and a button 80. The battery 50, the circuit board 60, and the holder 70 are all accommodated in the shell 40. A related control circuit is arranged on the circuit board 60. The control circuit is electrically connected to the battery 50 and a heating assembly 20 respectively for controlling the battery 50 to supply power to the heating assembly 20. The button 80 is arranged on the side wall of the shell 40 and is configured to receive an operation performed by a user, so as to turn on the circuit board 60 to control the battery 50 to supply power to the heating assembly 20.

[0028] The shell 40 may be in the shape of a cylinder, and may include a first shell 41 in the cylindrical shape and located outside and a second shell 42 in the cylindrical shape and located inside. The second shell 42 may be a hard shell, which provides support and protection. The first shell 41 is sleeved outside the second shell 42. The first shell 41 may be made of a soft material such as a soft glue, or the like, which may improve a touch feeling for a user.

[0029] In some embodiments, the holder 70 may include a holder body 71 accommodated in the shell 40 and a sleeve portion 72 extending upward from the top wall of the holder body 71. The holder body 71 may be in the shape of a cylinder having the opening on the side. The battery 50 may be accommodated in the holder body 71, and the circuit board 60 may be arranged on the side of the holder body 71 having the opening and arranged corresponding to the button 80. The sleeve portion 72 may be in the shape of a cylinder, and may be formed by integrally extending upward from the top wall of the holder body 71. The sleeve portion 72 may extend out of the shell 40 and is configured to be sleeved on and connected to the heating assembly 20.

[0030] The atomizer 100 may include a condensation cap with nozzle10 defining an accommodating cavity 1130 and the heating assembly 20 accommodated in the accommodating cavity 1130. The condensation cap with nozzle 10 is arranged above the main unit 200 along the longitudinal direction and may be detachably connected to the main unit 200 by screwing, magnetic connection, engagement, or the like. The heating assembly 20 includes a heating bowl 21, and an atomization cavity 210 configured to accommodate and heat the aerosol-forming substance is defined in the heating bowl 21. A cooling channel 110 and an inhalation channel 120 in communication with the atomization cavity 210 in sequence are defined in the condensation cap with nozzle 10. An aerosol generated after the aerosol-forming substance is heated and atomized is cooled through the cooling channel 110 and then outputted through the inhalation channel 120 to be inhaled by a user.

[0031] In some embodiments, the condensation cap with nozzle 10 may be made of glass or the like, and may include a cap body 11 and a nozzle 12 connected to the cap body 11. The inhalation channel 120 is defined in the nozzle 12, and the cooling channel 110 is defined in the cap body 11. Condensed water may be further provided in the cooling channel 110. The aerosol passes through the condensed water to be condensed and to filter out an impurity in the aerosol to be inhaled by the user.

[0032] As shown in FIG. 3 to FIG. 4, in some embodiments, the cap body 11 may include an outer cap 115, and a first isolating wall 113 and a second isolating wall 114 which are arranged in the outer cap 115. The outer cap 115 may be substantially in the shape of a cylinder, and the outer diameter thereof may be the same as the outer diameter of the shell 40. The top of the outer cap 115 has an annular top wall 1151. The top wall 1151 may cover the upper end of the cooling channel 110, and the inner wall surface of the top wall 1151 defines a first opening 1152 in communication with the accommodating cavity 1130. The bottom of the outer cap 115 has an annular bottom wall 1153. The bottom wall 1153 may cover the lower end of the cooling channel 110, and the inner wall surface of the bottom wall 1153 defines a second opening 1154 in communication with the accommodating cavity 1130. The cap body 11 may further include an annular connection portion 1155 defined by integrally extending downward from the lower end surface of the bottom wall 1153. At least one spiral engagement protrusion 1156 that protrudes outward may be arranged on the outer wall surface of the connection portion 1155, and at least one spiral engagement groove 421 is correspondingly defined on the inner wall surface of the upper end of the second shell 42. The spiral engagement protrusion 1156 is rotatably engaged in the spiral engagement groove 421 to mount the atomizer 100 to the main unit 200. In some embodiments, two spiral engagement protrusions 1156 are arranged. Each of the spiral engagement protrusions 1156 extends along the circumferential direction of the connection portion 1155, and the two spiral engagement protrusions 1156 are respectively rotationally and symmetrically arranged on the two sides of the connection portion 1155 in the circumferential direction. Correspondingly, two spiral engagement grooves 421 are arranged. The two spiral engagement grooves 421 are respectively rotationally and symmetrically arranged on the two sides of the second shell 42 in the circumferential direction. Each of the spiral engagement grooves 421 has a guide end 4211 and a locking end 4212 arranged oppositely along the circumferential direction. During assembly, the spiral engagement protrusion 1156 is guided into the spiral engagement groove 421 along the guide end 4211, and is then rotated by a set angle (for example, 10° to 30°) to the locking end 4212, so as to lock and fix the condensation cap with nozzle 10 to the second shell 42. During disassembly, the condensation cap with nozzle 10 is rotated reversely by a set angle, so that the spiral engagement protrusion 1156 is rotated from the locking end 4212 to the guide end 4211. In this way, the condensation cap with nozzle 10 may be taken out from the second shell 42. The locking or take-out by rotation uses a simple structure and is convenient to operate.

[0033] The first isolating wall 113 may integrally extend downward from the top wall 1151 to the bottom wall 1153. The first isolating wall 113 may be annular and may be arranged coaxially with the outer cap 115. The inner wall surface of the first isolating wall 113 defines an accommodating cavity 1130 configured to accommodate the heating assembly 20. The inner diameter of the first isolating wall 113 may be substantially equal to the pore size of each of the first opening 1152 and the second opening 1154.

[0034] The second isolating wall 114 may integrally extend downward from the top wall 1151 to the bottom wall 1153, and the second isolating wall 114 may be annular and may be arranged coaxially with the outer cap 115. The second isolating wall 114 is located between the outer cap 115 and the first isolating wall 113, and is spaced apart from the outer cap 115 and from the first isolating wall 113, respectively, that is, there is a gap is defined between the second isolating wall 114 and the outer cap 115, or defined between the second isolating wall 114 and the first isolating wall 113. A first cooling channel 111 is defined between the inner wall surface of the second isolating wall 114 and the outer wall surface of the first isolating wall 113, and a second cooling channel 112 is defined between the outer wall surface of the second isolating wall 114 and the inner wall surface of the outer cap 115. That is, the accommodating cavity 1130, the first cooling channel 111, and the second cooling channel 112 all extend along the longitudinal direction. The first cooling channel 111 is annular and is arranged on the periphery of the accommodating cavity 1130, and the second cooling channel 112 is annular and is arranged on the periphery of the first cooling channel 111. Since the first cooling channel 111 and the second cooling channel 112 are annular, a relatively large accommodating space is available for accommodating a condensate.

[0035] At least one first air outlet 1131 configured to communicate the accommodating cavity 1130 with the first cooling channel 111 is arranged on the first isolating wall 113, and at least one second air outlet 1141 configured to communicate the first cooling channel 111 with the second cooling channel 112 is arranged on the second isolating wall 114. The first air outlet 1131, the first cooling channel 111, the second air outlet 1141, and the second cooling channel 112 are in communication in sequence to define the cooling channel 110. In this embodiment, two first air outlets 1131 are symmetrically arranged on the two sides of the first isolating wall 113 in the circumferential direction. Two second air outlets 1141 are symmetrically arranged on the two sides of the second isolating wall 114 in the circumferential direction. The two second air outlets 1141 may be respectively arranged corresponding to the two first air outlets 1131, that is, one of the two second air outlets 1141 may be arranged corresponding to one of the two first air outlets 1131, and the other one of the two second air outlets 1141 may be arranged corresponding to the other of the two first air outlets 1131. That is, a connecting line between the two second air outlets 1141 may be parallel to a connecting line between the two first air outlets 1131. It may be understood that in other embodiments, one or more first air outlets 1131 and one or more second air outlet 1141 may be arranged. In some other embodiments, an included angle may be formed between the connecting line between the two second air outlets 1141 and the connecting line between the two first air outlets 1131. For example, the included angle is 90 degrees.

[0036] In some embodiments, a flowing direction of the aerosol in the first cooling channel 111 and the second cooling channel 112 is opposite to a flowing direction of the second cooling channel 112. The first air outlet 1131 is arranged on the side wall of the upper end of the first isolating wall 113, and may be located below the top wall 1151 and close to the top wall 1151. The second air outlet 1141 may be arranged on the side wall of the lower end of the second isolating wall 114 and close to the bottom wall 1153. The upper end of the second cooling channel 112 is in communication with the inhalation channel 120, so that the path of the cooling channel 110 is relatively long, thereby implementing more effective condensation and filtering.

[0037] In some embodiments, the atomizer 100 may further include a seal plug 30 detachably arranged at the first opening 1152. A vent hole 320 may be defined on the seal plug 30 along the longitudinal direction. The vent hole 320 is in communication with the atomization cavity 210 and may be arranged coaxially with the atomization cavity 210, so as to communicate the atomization cavity 210 with an outside. In some embodiments, the seal plug 30 may include an annular seal portion 31 and a vent portion 32 penetrating the seal portion 31. The outer wall surface of the seal portion 31 is hermetically engaged with a hole wall of the first opening 1152. The seal portion 31 may be made of an elastic material such as silica gel, which has a good sealing effect and may be easily inserted and removed. The vent portion 32 penetrates the seal portion 31 along the longitudinal direction, and the vent hole 320 is defined on the vent portion 32 along the longitudinal direction. The vent portion 32 may be made of a hard material such as glass, so that air passes through the vent hole 320 smoothly, thereby preventing blocking of the vent hole 320. The vent portion 32 may include a top portion 321 located above and a rod portion 322 located below. The outer diameter of the top portion 321 is greater than that the outer diameter of the rod portion 322. The top portion 321 is embedded into the seal portion 31, and the rod portion 322 may pass through the seal portion 31 and extend downward into the atomization cavity 210. The outer diameter of the rod portion 322 is less than the inner diameter of the heating bowl 21, so that a first vent gap 3220 configured for facilitating gas circulation is defined between the outer wall surface of the rod portion 322 and the inner wall surface of the heating bowl 21. A second vent gap 310 that communicates the first vent gap 3220 with the first air outlet 1131 is further defined between the upper end surface of the heating assembly 20 and the lower end surface of the seal portion 31. As shown by arrows in FIG. 3, the air enters the atomization cavity 210 through the vent hole 320, and is mixed with an aerosol generated after atomization in the atomization cavity 210, and an atomized gas obtained after the air is mixed with the aerosol enters the upper end of the first cooling channel 111 through the first vent gap 3220, the second vent gap 310, and the first air outlet 1131 in sequence, and flows downward in the first cooling channel 111 to the second air outlet 1141 at the lower end, and then the atomized gas enters the second cooling channel 112 through the second air outlet 1141 and flows upward in the second cooling channel 112, and is finally outputted through the inhalation channel 120.

[0038] The nozzle 12 may be tubular. The inner wall surface of the nozzle 120 defines the inhalation channel 120. The nozzle 12 may be arranged on the side of the outer cap 115 corresponding to one of the second air outlets 1141, and may be formed by integrally extending from the outer wall surface of the outer cap 115. The nozzle 12 has an inhalation end 121 away from the outer cap 115 and a connection end 122 connected to the outer cap 115. The nozzle 12 may be arranged obliquely upward, so that the position where the inhalation end 121 is disposed is higher than the position where the connection end 122 is disposed, which facilitates inhalation by the user. The outer diameter and the inner diameter of the nozzle 12 may gradually decrease along the direction from the connection end 122 toward the inhalation end 121, so that the pore size of the inhalation channel 120 gradually decreases along the direction from the connection end 122 toward the inhalation end 121. In this way, the aerosol at the inhalation end 121 is more concentrated, and inhalation experience is more desirable. In addition, the outer diameter of the nozzle 12 at the inhalation end 121 is relatively small, which helps the user hold the nozzle in the mouth.

[0039] As shown in FIG. 5 to FIG. 6, the heating assembly 20 includes a heating bowl 21, a base 22, an elastic engagement member 23, a self-locking member 24, and a limiting member 25. The base 22 is connected to the end of the self-locking member 24 and is jointly accommodated in the limiting member 25 with the self-locking member 24. The self-locking member 24 has a locked state of being engaged with the limiting member 25 and an unlocked state of being disengaged from the limiting member 25. The heating bowl 21 is movably accommodated in the limiting member 25 and is supported by the base 22, and the heating bowl 21 is pressed against the self- locking member 24 through the base 22 to switch between the locked state and the unlocked state between the self-locking member 24 and the limiting member 25.

[0040] The heating bowl 21 is movable between a first position and a second position relative to the limiting member 25. The self-locking member 24 is driven to switch from the locked state to the unlocked state when the heating bowl 21 is pressed at the first position. The self-locking member 24 pushes the heating bowl 21 to move to the second position when the self-locking member 24 is driven to switch from the locked state to the unlocked state. When the heating bowl 21 is pressed at the second position, the self-locking member 24 is pushed to move and the self- locking member 24 is driven to switch from the unlocked state to the locked state.

[0041] When the heating bowl 21 is at the first position, the heating bowl 21 is accommodated in the limiting member 25. When the heating bowl 21 is at the second position, the heating bowl 21 is at least partially located outside the limiting member 25, so that the user may easily disassemble the heating bowl 21 from the base 22 and assemble the heating bowl 21 on the base 22. In other words, by applying a pressing force to the heating bowl 21, the heating bowl 21 may be accommodated in the limiting member 25, or the heating bowl 21 may be lifted from the limiting member 25 until a part of the heating bowl 21 is exposed outside the limiting member 25, so that the user may easily disassemble and assemble the heating bowl 21.

[0042] As shown in FIG. 7 and FIG. 8, the heating bowl 21 may be in the shape of a cylinder, the inner wall surface of the heating bowl 21 defines the atomization cavity 210 configured to accommodate the aerosol-forming substance, and at least one vent opening 2110 configured to communicate the atomization cavity 210 with the first air outlet 1131 may be further defined on the side wall of the heating bowl 21. The heating bowl 21 may be made of a ceramic material, for example, an environmentally friendly ceramic material such as alumina, aluminum nitride, silicon nitride, or the like, which is harmless to a human body when heated at high temperature. The heating bowl 21 has a heating surface 2121. A heating element 213 is arranged on the heating surface 2121 and is configured to generate heat after being energized.

[0043] In some embodiments, the heating bowl 21 includes a bowl body 211 and a bowl bottom 212 located at the bottom of the bowl body 211. The outer diameter of the bowl body 211 is less than the outer diameter of the bowl bottom 212. Two vent openings 2110 are symmetrically arranged on the two sides of the bowl body 211 in the circumferential direction. Each of the vent openings 2110 may be formed by extending downward on the top surface of the side wall of the bowl body 211. The two vent openings 2110 may be respectively arranged corresponding to the two first air outlets 1131, that is, one of the two vent openings 2110 may be arranged corresponding to one of the two first air outlets 1131, and the other one of the two vent openings 2110 may be arranged corresponding to the other of the two first air outlets 1131. That is, the connecting line between the two second vent openings 2110 may be parallel to the connecting line between the two first air outlets 1131. It may be understood that in other embodiments, an included angle may be formed between the connecting line between the two vent openings 2110 and the connecting line between the two first air outlets 1131. For example, the included angle is 90 degrees.

[0044] The bottom surface of the bowl bottom 212 forms the heating surface 2121 for arranging the heating element 213. The heating element 213 includes a heating body. The heating body may be a heating film and may be formed on the heating surface 2121 by screen printing or the like. It may be understood that in other embodiments, the heating body is not limited to the heating film. For example, the heating body may be a metal heating sheet. In this embodiment, the heating element 213 further includes an annular first electrode portion 214 electrically connected to one electrode of the heating body and a second electrode portion 215 electrically connected to another electrode of the heating body and located inside the first electrode portion 214. The second electrode portion 215 is annular and is located in a middle portion of the bottom surface of the bowl bottom 212, the first electrode portion 214 surrounds the second electrode portion 215 and is arranged coaxially with the second electrode portion 215, and the inner diameter of the first electrode portion 214 is greater than the outer diameter of the second electrode portion 215. With the arrangement of the electrode portions, it is not necessary for alignment of the heating bowl 21 during assembly, thereby achieving a foolproof effect.

[0045] As shown in FIG. 8 and FIG. 9, the base 22 is arranged with a first electrode 221 and a second electrode 222, and the base 22 is configured to carry the heating bowl 21, where the first electrode 221 and the second electrode 222 are configured to be electrically connected to the heating bowl 21.

[0046] The base 22 may be made of a ceramic material. In other embodiments, the base may be made of other materials such as plastic. The base 22 may include a base body 223 and a cover body 224, the base body 223 engages with the cover body 224 to clamp and fix the first electrode 221 and the second electrode 222. The first electrode 221 and the second electrode 222 run through the cover body 224 to extend toward a bowl bottom 212 of the heating bowl 21, and are configured to be electrically connected to the first electrode portion 214 and the second electrode portion 215 correspondingly; the base body 223 and the cover body 224 are connected and fixed by a fastener, for example, a bolt and a circlip may be used; and both the base body 223 and the cover body 224 are accommodated in the limiting member 25, and at least one limiting portion 225 extends outward from the side wall of the base body 223. The at least one limiting portion 225 is configured to limit a position of the base 22 in the limiting member 25. In this embodiment, two limiting portions 225 are arranged. The two limiting portions 225 are respectively arranged on the two opposite sides of the base body 223, that is, one of the two limiting portions 225 may be arranged on one of the two opposite sides of the base body 223, and the other one of the two limiting portions 225 may be arranged on the other of the two opposite sides of the base body 223.

[0047] Both the first electrode 221 and the second electrode 222 are elastic electrodes, and elastically abut against the first electrode portion 214 and the second electrode portion 215 respectively, that is, one of the first electrode 221 and the second electrode 222 may elastically abut against one of the first electrode portion 214 and the second electrode portion 215, and the other one of the first electrode 221 and the second electrode 222 may elastically abut against the other one of the first electrode portion 214 and the second electrode portion 215, and contact and are connected to the first electrode portion 214 and the second electrode portion 215.

[0048] In this embodiment, both the first electrode 221 and the second electrode 222 are elastic electrode poles.

[0049] In some embodiments, both the first electrode 221 and the second electrode 222 are metal elastic sheets.
