The liquid guide ports 312 may be arranged circumferentially along the atomizing seat 31 and may be divided into at least two parts by at least one partition 212 in the liquid storage cavity 211. For example, they may be divided into two parts by one partition 212, one part of which may communicate with the first liquid storage cavity 211a and the corresponding heating structure 32, and the other part may communicate with the second liquid storage cavity 211b and the corresponding heating structure 32.

The cylindrical body 3211 may be cylindrical and have a central channel 3213 on its inner side. The positioning protrusion 3212 protrudes from the side wall of the cylindrical body 3211 and can pass through a window 311, thereby fixing the heating structure 32 to the atomizing base 31. In this embodiment, there may be one heating element 322, which is disposed on the atomizing core 321. Specifically, the heating element 322 may be disposed in the central through-hole 3213 of the atomizing core 321 and fit against the inner wall of the atomizing core 321. In some other embodiments, the heating element 322 may not be limited to one, and there may be two. In this embodiment, the heating element 322 can be mesh-like, which can be a metal mesh and can be wound into a hollow columnar structure.

[0067] In this embodiment, each heating structure 32 further includes a conductive connector 323. Each heating structure may have two conductive connectors 323, which can be conductive wires.

In this embodiment, one conductive connector 323 of the two heating structures 32 can be shared, resulting in a total of three conductive connectors 323 for the two heating structures 32. That is, the two heating structures 32 can be arranged in parallel, which facilitates individual heating of each liquid storage chamber 211. In other embodiments, the conductive connectors 323 of each heating structure 32 may not be shared.

[0068] In this embodiment, the atomizing assembly 30 further includes an isolation seal 33, which can be disposed between two sets of heating structures 32.

Specifically, it can seal at least a portion of the gap between the seal 24 and the atomizing seat 31, thereby preventing the liquid atomizing matrix in the two adjacent liquid storage chambers 211 from flowing into each other and affecting the taste of the aerosol, and preventing leakage. In this embodiment, the isolation seal 33 is disposed between two adjacent sets of heating structures 32, and can be a single seal. Specifically, the isolation seal 33 can be disposed between the first heating structure 32a and the second heating structure 32b. In some other embodiments, the isolation seal 33 may be limited to one or more. One or more isolation seals 33 may be provided between two adjacent sets of heating structures 32. In this embodiment, the two ends of the isolation seal 33 may at least partially abut against the two adjacent heating structures 32, thereby isolating the two adjacent heating structures 32.

[0069] In this embodiment, the isolation seal 33 may be cylindrical and have a through-end structure, allowing it to communicate with the heating structure 32. Specifically, the isolation seal 33 may be disposed in the atomizing seat 31 and tightly fitted with it. The outer wall of the isolation seal 33 may be in close contact with the inner wall of the atomizing seat 31 and coaxially arranged with the two sets of heating structures 32. The isolation seal 33 may partially protrude from the window 311 and contact and seal with the partition 212. Specifically, the isolation seal 33 may include a main body 331 and an extending protrusion 332. The main body 331 is generally sheet-like and may be wound into a cylindrical shape, having a through-end structure. The extending protrusion 332 may be disposed on two opposite sides of the main body 331 and bent to fit with the main body 331. When the main body 331 is wound into a cylindrical structure, the extending protrusion 332 may protrude from one side of the main body 331. When the isolation seal 33 is assembled with the atomizing base 31, the extended protrusion 332 can protrude from the window 311 and make close contact with the inner wall of the first mounting hole 2120 of the partition 212. In some other embodiments, the isolation seal 33 may not be limited to being disposed in the atomizing base 31, and the extended protrusion 332 may be omitted.

[0070] In this embodiment, the isolation seal 33 can be an elastic seal, such as a silicone seal. Of course, it is understood that in other embodiments, the isolation seal 33 may not be limited to silicone and may be other seals.

[0071] In this embodiment, the atomizing assembly 30 further includes an atomizing tube 34, which can be an airway fitting and can be disposed at one end of the heating structure 32 facing the suction port 141. The atomizing seat 31 can be sleeved on the outer periphery of a portion of the atomizing tube 34 and can be fixed to the atomizing tube 34 by an interference fit. In this embodiment, the end of the atomizing tube 34 away from the heating structure 32 can be inserted into the air outlet 231 and then fixed to the second end cap 23. In some embodiments, the atomizing tube 34 can also be an integral structure with the atomizing seat 31.

[0072] like Figure 9As shown, in this embodiment, the atomizing assembly 30 further includes a wire-clamping structure 35, which is disposed in the atomizing base 31 and located at the second end 31b of the atomizing base 31. The wire-clamping structure 35 can be cylindrical and can be a through-type structure at both ends. The wire-clamping structure 35 can be a cylindrical structure with a circular cross-section, and the outer diameter of the middle section can be larger than the outer diameter of the two ends. Part of the outer wall of the wire-clamping structure 35 can be fixed to the inner wall of the atomizing base 31 through close contact. The wire-clamping structure 35 has an air passage 351, which can be located at the central axis of the wire-clamping structure 35, allowing external airflow to enter the atomizing assembly 30. The outer wall of the wire-clamping structure 35 can be provided with wire-clamping grooves 352. There can be multiple wire-clamping grooves 352, which can be spaced apart along the circumference of the wire-clamping structure 35. Each conductive connector 323 can be clamped in one wire-clamping groove 352. In some embodiments, there may be one wire slot 352, in which all conductive connectors 323 may be secured, and adjacent conductive connectors 323 may be insulated from each other by setting an insulating structure, such as an external insulating structure for the conductive connectors 323.

[0073] By setting up this wire-locking structure 35, there is no need to open a separate wiring channel, which simplifies the manufacturing process of the liquid storage structure 20 and facilitates the miniaturization design of the liquid storage structure 20. In addition, it can be easily assembled.

[0074] When assembling the atomizing component 30, the atomizing core 321 of the heating structure 32 and the isolation seal 33 can be wrapped around the heating element 322 with the help of a cotton swab, and simultaneously inserted into the atomizing base 31 along the window 311 of the atomizing base 31. Finally, the wire clamping structure 35 is used to clamp the conductive connector 323 of the heating structure 32 into the atomizing base 31 to prevent the heating element 322 from deforming due to contact with the conductive connector 323.

[0075] In this embodiment, the power supply component 40 may include a bracket 41 and a power supply 42. The bracket 41 may be disposed in the housing 10, located at one end of the liquid storage structure 20, and may be snapped and fixed to the second cover 13. The bracket 41 may support the liquid storage structure 20 and may be snapped and fixed to the first end cover 22. The power supply 42 may be disposed on the bracket 41 and may be connected to the conductive connector 323.

[0076] In this embodiment, the electronic atomizing device also includes a sealing component 50, which is detachably sealed to the suction port 141. It can be used to seal the suction port 141 when the electronic atomizing device is not in use, so as to prevent dust and moisture from entering the electronic atomizing device.

[0077] Figures 10 to 13The second embodiment of the electronic atomizing device of the present invention is shown. The difference between the second and first embodiments is that the isolation seal 33 can be sleeved on the outer periphery of the atomizing seat 31, the extended protrusion 332 can be omitted, and the outer peripheral wall of the isolation seal 33 can be in close contact with the partition 212. Specifically, the isolation seal 33 can be in close contact with the partition 212 through the seal 24.

[0078] When assembling the atomizing component 30, the atomizing core 321 of the heating structure 32 can be wrapped around the heating element 322 with the assistance of a cotton swab, and simultaneously inserted into the atomizing base 31 along the window 311 of the atomizing base 31. Then, an isolation sealing member 33 is fitted onto the atomizing base 31, and the isolation sealing member 33 is placed between two adjacent heating structures 32. Finally, the wire clamping structure 35 is used to clamp the conductive connector 323 of the heating structure 32 into the atomizing base 31 to prevent the heating element 322 from deforming due to contact with the conductive connector 323.

[0079] Figures 14 to 17 The third embodiment of the electronic atomizing device of this utility model is shown. The difference from the first embodiment is that the number of heating elements 322 in each group of heating structures 32 can be different. Specifically, the first heating structure 32a can have two heating elements 322, which can be spaced apart along the axial direction of the atomizing core 321. The second heating structure 32b can have only one heating element 322.

[0080] Figures 18 to 21 The fourth embodiment of the electronic atomizing device of the present invention is shown. The difference between the fourth and third embodiments is that the isolation seal 33 can be sleeved on the outer periphery of the atomizing seat 31, the extended protrusion 332 can be omitted, and the outer peripheral wall of the isolation seal 33 can be in close contact with the partition 212. Specifically, the isolation seal 33 can be in close contact with the partition 212 through the seal 24.

[0081] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
