[0028] like Figure 1 and Figure 2 As shown, the present application provides an atomizing device, which can be used for atomizing an aerosol-generating substrate. The atomizing device includes a housing assembly 10, a circuit board assembly 30, and a battery 40. The housing assembly 10 has an atomizing device installation position 11 inside, and the atomizing device installation position 11 is used to install the atomizing device 20.

[0029] like Figure 1 and Figure 2 As shown, the atomizing device 20 is a device for atomizing an aerosol generating matrix to generate an aerosol. Generally, the interior of the atomizing device 20 includes a mounting shell 21, a tube body 22, a liquid guide 23 and a heating element 24. The mounting shell 21 is mounted on the atomizing device mounting position 11, and the tube body 22 is arranged inside the mounting shell 21. The space between the mounting shell 21 and the tube body 22 is a liquid storage cavity, and the interior of the liquid storage cavity stores an aerosol generating matrix. The aerosol generating matrix can be, for example, tobacco oil, liquid medicine, etc. Further, the atomizing device 20 can also include a liquid storage part 26, which is arranged inside the liquid storage cavity. The material of the liquid storage part 26 can be a porous material, and the aerosol generating matrix is ​​accommodated in the pores of the liquid storage part 26. The material of the liquid storage part 26 can be, for example, cotton fiber, porous ceramics, etc.

[0030] An atomizing channel 222 is formed inside the tube body 22, and a liquid guide 23 is arranged inside the atomizing channel 222. A connecting hole 221 is provided on the tube body 22, and the connecting hole 221 is used to allow the aerosol generating matrix in the liquid storage chamber to be introduced into the liquid guide 23. The liquid guide 23 can be made of a porous material, such as cotton fiber, porous ceramic, etc. A heating element 24 is arranged inside the liquid guide 23, and a wiring portion 25 is arranged at one end of the heating element 24, and the wiring portion 25 is electrically connected to the circuit board assembly 30.

[0031] The housing assembly 10 is also provided with an air inlet channel 12, which is used to communicate with the atomizing channel 222 of the atomizing device 20. In addition, the atomizing device may further include a nozzle 50, which is mounted at one end of the housing assembly 10 away from the air inlet channel 12. The nozzle 50 may be detachably connected to the housing assembly 10, or may be integrally formed with the housing assembly 10. An air outlet channel 51 is provided inside the nozzle 50, which is used to communicate with one end of the atomizing channel 222 away from the air inlet channel 12. When the user draws air, the gas enters the air inlet channel 12 from the air inlet 121 of the air inlet channel 12, flows from the air inlet channel 12 to the atomizing channel 222, and carries the aerosol atomized in the atomizing channel 222 to flow to the air outlet channel 51, and finally flows out from the air outlet channel 51 of the nozzle 50.

[0032] The atomizing device may not include the atomizing device 20, and only the atomizing device installation position 11 is provided inside the housing assembly 10. The atomizing device 20 as a consumable can be detachably assembled with the circuit board assembly 30, the housing assembly 10, etc. Of course, the atomizing device 20 may also include the atomizing device 20, and the atomizing device 20 may be detachably assembled with the circuit board assembly 30, the housing assembly 10, etc., or may be integrally arranged with the housing assembly 10.

[0033] Please refer to Figure 1 The housing assembly 10 cooperates with the circuit board assembly 30 to form a battery assembly space 60, the battery assembly space 60 is separated from the air inlet passage 12, and the battery 40 is disposed inside the battery assembly space 60 and is electrically connected to the circuit board assembly 30. Specifically, as Figure 3 As shown, an opening 311 may be provided on the circuit board assembly 30, and the battery 40 may include a battery electrode (not shown) and a pin (not shown), one end of the pin being electrically connected to the battery electrode, and the other end of the pin passing through the opening 311 being electrically connected to the circuit board assembly 30.

[0034] The atomizing device of the present application configures the battery assembly space 60 to be separated from the air inlet channel 12. When the user inhales, the heat and odorous waste gas generated by the battery 40 will be blocked inside the battery assembly space 60 and will not be inhaled into the mouth of the user along the airway, effectively preventing the problem of heat and odorous waste gas affecting the taste of smoking. In addition, the present application uses the circuit board assembly 30 as a part of the structure forming the battery assembly space 60, which is conducive to the connection between the battery 40 and the circuit board assembly 30. There is no need to open additional holes on the side wall of the battery assembly space 60 for the connection between the battery 40 and the circuit board assembly 30, making the space inside the atomizing device more compact.

[0035] In one embodiment, if Figure 1-Figure 3As shown, the circuit board assembly 30 includes a first circuit board 31. At least a portion of the first circuit board 31 cooperates with the shell assembly 10 to form a battery assembly space 60. Specifically, the shell assembly 10 has a first side 13 and a second side 14 that are opposite to each other. The first side 13 of the shell assembly 10 is provided with an air inlet 121 of the air inlet channel 12, and the second side 14 of the shell assembly 10 is provided with an atomization device mounting position 11 and a suction nozzle 50. The first circuit board 31 is located on a side of the atomization device mounting position 11 close to the air inlet 121, and the first circuit board 31 is used to be electrically connected to the atomization device 20; the battery assembly space 60 is located on a side of the first circuit board 31 away from the atomization device mounting position 11, that is, the battery 40 is located on a side of the first circuit board 31 away from the atomization device mounting position 11. For example, in a case such as Figure 1-3 In the illustrated embodiment, with reference to the illustrated direction, the atomization device 20 is mounted above the first circuit board 31, and the battery 40 is mounted below the first circuit board 31. In this embodiment, the first circuit board 31 can also effectively separate the battery assembly space 60 from the atomization device 20 to prevent the exhaust gas generated by the battery 40 from directly diffusing from the first circuit board 31 to the atomization channel 222.

[0036] Furthermore, if Figure 1-5 As shown, an electrode 312 and a microphone 313 are arranged on the first circuit board 31 of the circuit board assembly 30. The microphone 313 is arranged on one side of the first circuit board 31 close to the air inlet channel 12. The microphone 313 is mainly used in the atomization device 20 to receive the user's inhalation signal, so as to control the start and stop of the atomization device.

[0037] The atomization device also includes a microphone head protection member 70, which is covered on one side of the first circuit board 31 close to the atomization device 20. The microphone head protection member 70 is provided with an atomization device installation position 11 on the side close to the atomization device, and the mounting shell 21 is provided on the atomization device installation position 11. The mounting shell 21 is provided with an electrode mounting hole 211 and a wiring portion channel 212 at one end close to the circuit board. The electrode 312 passes through the microphone head protection member 70 and is inserted into the inside of the electrode mounting hole 211. The wiring portion 25 passes through the wiring portion channel 212 and is sandwiched between the side wall of the electrode mounting hole 211 and the electrode 312. Through the above structure, the electrical connection between the battery 40 and the heating element 24 can be achieved. Of course, in other embodiments, the wiring portion 25 can also pass through the wiring portion channel 212 and the microphone head protection member 70 in sequence and be directly electrically connected to the first circuit board 31. This connection method has some defects compared with the aforementioned connection method. It is difficult to realize fully automated assembly and production with this connection method. The aforementioned connection method can be that after the wiring part 25 is led out from the wiring part channel 212, the wiring part 25 is bent to the electrode mounting hole 211 by a fixture, and then the electrode 312 on the first circuit board 31 is inserted into the electrode mounting hole 211. The electrode 312 and the wiring part 25 are electrically connected in contact, and no welding is required. Moreover, the wiring part 25 is clamped between the electrode 312 and the side wall of the electrode mounting hole 211, which is not easy to have poor contact.

[0038] In one embodiment, if Figure 3 , Figure 6 and Figure 7 As shown, the housing assembly 10 includes a base 15 and a bracket 16. In this embodiment, the base 15 and the bracket 16 are detachably connected. In other embodiments, the base 15 and the bracket 16 may also be integrally formed.

[0039] The base 15 includes a mounting seat 151 and a partition 152 disposed on the mounting seat 151. The bracket 16 is mounted on the mounting seat 151, and a mounting cavity 161 is formed inside the bracket 16. The circuit board assembly 30 includes a first circuit board 31, at least a portion of the first circuit board 31 and the partition 152 are disposed inside the mounting cavity 161, and one end of the partition 152 away from the mounting seat 151 abuts against a side of the first circuit board 31 away from the atomization device 20, so as to divide the mounting cavity 161 into an air inlet channel 12 and a battery assembly space 60 located on both sides of the partition 152.

[0040] More specifically, in one embodiment, the first circuit board 31 is a first circuit board 31 arranged approximately horizontally. The first circuit board 31 is disposed in the mounting cavity 161, and the mounting cavity 161 is divided into an upper cavity and a lower cavity. The partition 152 is inserted into the mounting cavity 161 from the bottom of the mounting cavity 161, and abuts against the side of the first circuit board 31 away from the atomization device 20, so as to divide the lower cavity into a portion of the air inlet channel 12 located on the left and right sides of the partition 152 and a battery assembly space 60. An air inlet 121 of the air inlet channel 12 is provided on the base 15, and the air inlet 121 is provided on one side of the partition 152 to be spaced from the battery assembly space 60. In this embodiment, the upper cavity can be used to install the atomization device 20. Of course, in other embodiments, the atomization device 20 can also be installed outside the bracket 16.

[0041] In one embodiment, if Figure 6 As shown, two reinforcing parts 1521 are provided on the partition 152. The partition 152, the two reinforcing parts 1521 and the bracket 16 cooperate to form the air inlet channel 12. The mounting seat 151 of the base 15 is provided with an air inlet 121 of the air inlet channel 12. By providing the reinforcing parts 1521 on the partition 152, on the one hand, the partition 152 can be strengthened and fixed to improve the structural strength of the partition 152, and on the other hand, the gas entering the atomization device from the base 150 can be guided.

[0042] In one embodiment, if Figure 2 , Figure 6 and Figure 7 As shown, the battery 40 is cylindrical, that is, the battery 40 is configured as a cylindrical battery. Based on this, the housing assembly 10 further includes a shell 17, and at least part of the shell 17 is cylindrical. Figure 2 In the embodiment, the shape of one side of the housing 17 is quasi-cylindrical, and the shape of the other side of the housing 17 is a rectangular parallelepiped structure. At least part of the bracket 16 and at least part of the partition 152 are bent to form an arc surface structure, so that the bracket 16, the partition 152, the mounting seat 151 and the first circuit board 31 cooperate to form a quasi-cylindrical battery assembly space 60. By adjusting the shapes of the housing 17, the bracket 16 and the partition 152 as above, the battery assembly space 60 can be adjusted to a quasi-cylindrical space to match the cylindrical battery, thereby reasonably optimizing the space inside the atomization device.

[0043] In one embodiment, if Figure 1 and Figure 3As shown, the circuit board assembly 30 also includes a second circuit board 32, one end of the first circuit board 31 is fixed to the second circuit board 32, and an angle is formed between the first circuit board 31 and the second circuit board 32. The angle can be, for example, about 90 degrees, for example, 85°-95°. Since the first circuit board 31 is generally arranged horizontally, the second circuit board 32 is arranged vertically.

[0044] A key assembly 321 may be provided on the second circuit board 32. Since the second circuit board 32 is provided vertically, the key assembly 321 may be easily exposed from the side wall of the housing 17 of the housing assembly 10 for user touch control. By arranging the first circuit board 31 and the second circuit board 32 in different directions, it is convenient to arrange the parts on the circuit board in a reasonable manner according to their required arrangement positions.

[0045] In one embodiment, if Figure 3 and Figure 7 As shown, the second circuit board 32 is arranged outside the installation cavity 161, and a portion of the first circuit board 31 extends to the outside of the installation cavity 161 through the air inlet passage 12 and is connected to the second circuit board 32. The portion of the first circuit board 31 located in the air inlet passage 12 is provided with a through hole 314, and the through hole 314 is used for the airflow inside the air inlet passage 12 to pass through, that is, the through hole 314 connects the air inlet passage 12 in the upper cavity and the lower cavity.

[0046] Since the second circuit board 32 further needs to be provided with a key assembly 321, a light emitting element 322, etc., the key assembly 321 needs to be exposed from a part of the housing 17, the light emitting element 322 needs to be irradiated onto the outer surface of the bracket 16, and the bracket 16 needs to assume a part of the light guiding function, the second circuit board 32 needs to be provided outside the mounting cavity 161, so as to facilitate the key assembly 321 and the light emitting element 322 to achieve their respective functions. For example, in one embodiment, the bracket 16 is configured as a fully transparent or translucent bracket 16, the second circuit board 32 is provided outside the mounting cavity 161, and the light emitting element 322 is provided on the second circuit board 32, and the light emitting element 322 is provided opposite to the outer wall of the bracket 16, and the bracket 16 can guide light to present a bright effect on the appearance of the atomization device.

[0047] Furthermore, if Figure 3As shown, the first circuit board 31 includes a mounting portion 315 and a connecting portion 316, one end of the connecting portion 316 is fixed to the second circuit board 32, and the other end of the connecting portion 316 is connected to the mounting portion 315, and the mounting portion 315 is provided with a through hole 314, a microphone 313, and an electrode 312. A clearance position 33 is formed between the mounting portion 315 and the second circuit board 32, and the bracket 16 is clamped at the clearance position 33. In this embodiment, the mounting portion 315 is located inside the mounting cavity 161 of the bracket 16, and at least part of the connecting portion 316 is located outside the mounting cavity 161 to connect the mounting portion 315 to the second circuit board 32. By clamping the bracket 16 at the clearance position 33, the clearance position 33 limits the movement of the bracket 16 in the horizontal direction, and the bracket 16 and the circuit board assembly 30 can be effectively fixed together.

[0048] Furthermore, if Figure 7 As shown, the bracket 16 has a first side wall 162 and a second side wall 163. The first side wall 162 and the second side wall 163 enclose an installation cavity 161. The first side wall 162 of the installation cavity 161 has a through installation opening 1621. The first side wall 162 has a clamping portion 1622 adjacent to the installation opening 1621. The clamping portion 1622 is clamped with the avoidance position 33.

[0049] like Figure 3 and Figure 7 As shown, the connecting portion 316 passes through the mounting opening 1621 and is connected to the second circuit board 32 outside the bracket 16. The first side wall 162 of the bracket 16 has a first end 1623 and a second end 1624 that are oppositely arranged in the horizontal direction, and at least a portion of the second side wall 163 is bent to form a curved surface structure, and the curved surface structure extends from the first end 1623 of the first side wall 162 to the second end 1624 of the first side wall 162. Since the second side wall 163 is a curved surface structure, in this embodiment, there are two positions of the avoidance positions 33, and the clamping portions 1622 are two opposite clamping portions 1622 adjacent to the mounting opening 1621, and the two clamping portions 1622 are respectively clamped with the two avoidance positions 33.

[0050] The first side wall 162 may be a plane and parallel to the second circuit board 32. In one embodiment, at least two ridges 1626 are provided at the bottom of the first side wall 162. The at least two ridges 1626 cooperate with the base 15 to form a circuit board mounting position 1625 for limiting the position of the second circuit board 32. The second circuit board 32 is disposed on the circuit board mounting position 1625. Specifically, in one embodiment, the number of the ridges 1626 is three, and the two side surfaces of the second circuit board 32 abut against two of the ridges 1626, the surface of the second circuit board 32 facing the first side wall 162 abuts against one ridge 1626, and the surface of the second circuit board 32 facing away from the first side wall 162 abuts against the base 15. The three ridges 1626 play a role in fixing and limiting the position of the second circuit board 32.

[0051] In one embodiment, one end of the second circuit board 32 away from the mounting seat 151 extends to the atomizer mounting position 11, and the second circuit board 32 is connected to the mounting shell 21, and the first circuit board 31, the second circuit board 32 and the mounting shell 21 cooperate to form at least part of the airway of the atomizer mounting position 11. By cooperating the second circuit board 32 with the mounting shell 21, it is possible to prevent the airflow of the air inlet channel 12 from not flowing to the atomizer channel 20, but from flowing out from the outside of the atomizer 20 above the first circuit board 31, thereby preventing the airflow loss from affecting the stability of the suction resistance.
