[0030] Example 1

[0031] like Figure 1-2 As shown, an embodiment of the present invention provides an atomizing core, including a support member 20, a liquid guiding assembly 30, and a heating element 1. The support member 20 includes a tubular support body 21 and baffle bodies 22 located at both ends of the tubular support body 21. The baffle bodies 22 and the tubular support body 21 together form a liquid storage space 23. The baffle bodies 22 have at least one inlet hole 221 for liquid to enter the liquid storage space 23. The liquid guiding assembly 30 is disposed around the outer periphery of the tubular support body 21. At least a portion of the tubular support body 21 is provided with an outlet hole 211 for liquid to flow out of the liquid storage space 23 to at least a portion of the liquid guiding assembly 30. The heating element 1 is disposed around at least a portion of the liquid guiding assembly 30 and is used to heat the atomized liquid.

[0032] In this embodiment, the atomizing core is formed by the tubular support 21 and the baffles 22 located at both ends of the tubular support 21 to form a liquid storage space 23. Since the baffles 22 have at least one inlet hole 221 for liquid to enter the liquid storage space 23, the atomizing liquid can be introduced into the liquid storage space 23 through the inlet hole 221. Since the liquid guiding component 30 is surrounded by the tubular support 21, the tubular support 21 supports the liquid guiding component 30. At least a portion of the tubular support 21 is provided with an outlet hole 211 for supplying liquid. The liquid flows out of the storage space 23 to at least a portion of the liquid guiding assembly 30. Therefore, the atomized liquid in the storage space 23 is guided to the liquid guiding assembly 30 through the liquid outlet 211. The heating element 1 surrounds at least a portion of the liquid guiding assembly 30 and is used to heat the atomized liquid. Therefore, the atomized liquid on the liquid guiding assembly 30 is heated by the heating element 1 to generate an aerosol. In this embodiment, the atomizing core can store the atomized liquid in the storage space 23 in the tubular support 21, which can ensure sufficient liquid supply to the liquid guiding assembly 30 and effectively reduce the risk of insufficient liquid supply to the liquid guiding assembly 30, which could lead to dry burning of the heating element 1.

[0033] In some embodiments, the liquid guiding assembly 30 includes a central liquid guiding 31 and end liquid guiding 32 located on both sides of the central liquid guiding 31. The end liquid guiding 32 is used to directly contact external liquid and can deliver liquid toward the central liquid guiding 31.

[0034] In this embodiment, the liquid guiding assembly 30 includes a central liquid guiding 31 and end liquid guiding 32 located on both sides of the central liquid guiding 31. Since the end liquid guiding 32 is used to directly contact the external liquid and can transport liquid toward the central liquid guiding 31, the end liquid guiding 32 can supply liquid to the central liquid guiding 31, reducing the problem of insufficient liquid supply to the central liquid guiding 31 and causing partial dry burning of the heating element 1. In addition, the end liquid guiding 32 can keep the two ends of the heating element 1 moist, which can not only play a pre-wetting role, but also assist in the liquid supply to the central liquid guiding 31, reducing the occurrence of dry burning.

[0035] In some embodiments, the liquid outlet 211 is located in the section of the middle liquid guide 31 directly opposite the tubular support 21. The liquid outlet 211 is used to supply liquid to the middle liquid guide 31. The middle liquid guide 31 can be used as the main liquid supply component, and the end liquid guide 32 can be used as the auxiliary liquid supply component. The middle liquid guide 31 can be supplied with concentrated liquid, reducing the problem of local dry burning of the heating element 1 due to insufficient local liquid supply to the middle liquid guide 31.

[0036] In some embodiments, the liquid outlet holes 211 are evenly distributed in a ring matrix in the area of ​​the central liquid guide 31 directly opposite the tubular support 21, which can provide more comprehensive and uniform liquid supply to the central liquid guide 31 and reduce the problem of local dry burning of the heating element 1 due to insufficient local liquid supply to the central liquid guide 31.

[0037] In some embodiments, the pore size and / or porosity of the end liquid guide 32 is smaller than that of the middle liquid guide 31. The middle liquid guide 31 can be used as the main liquid supply component, and the end liquid guide 32 can be used as the auxiliary liquid supply component. The middle liquid guide 31 can provide concentrated liquid supply, thereby reducing the problem of local dry burning of the heating element 1 due to insufficient local liquid supply to the middle liquid guide 31.

[0038] In some embodiments, the diameter of the inlet hole 221 is larger than the diameter of the outlet hole 211, ensuring that the atomizing liquid supply in the liquid storage space 23 inside the tubular support 21 is always sufficient, reducing the problem of insufficient liquid supply to the central liquid guide 31 due to lack of liquid in the liquid storage space 23, which may cause the heating element 1 to burn dry.

[0039] In some embodiments, the heating element 1 is mesh-shaped and surrounds the outer periphery of the central liquid guide 31. The mesh-shaped heating element 1 allows the atomized aerosol to flow out with the airflow in a timely manner.

[0040] In some embodiments, the heating element 1 is mesh-shaped and surrounds the outer periphery of the central liquid guide 31 and the end liquid guide 32. The heating element 1 can mainly heat the atomizing liquid on the central liquid guide 31 to achieve the main atomization effect, while the heating element 1 can also heat the atomizing liquid on the end liquid guide 32 to play an auxiliary atomization role.

[0041] Example 2

[0042] like Figure 1-4 As shown, this embodiment of the invention also provides an atomizer, including a housing 4, an atomizing support 5, an air outlet pipe 6, an electrode 7, and the atomizing core of Embodiment 1. The housing 4 has a liquid storage chamber 41. The atomizing support 5 is connected to the housing 4. The atomizing core is installed horizontally on the atomizing support 5. The heating element 1 of the atomizing core and the atomizing support 5 together form an atomizing cavity 51. The liquid inlet 221 and the end liquid guide 32 are respectively connected to the liquid storage chamber 41. The air outlet pipe 6 is connected to the atomizing support 5 and communicates with the atomizing cavity 51. The electrode 7 is electrically connected to the atomizing core.

[0043] The aforementioned atomizer, by having the atomizing core mounted horizontally on the atomizing bracket 5, allows the end liquid guide 32 to directly contact the liquid storage chamber 41 and deliver liquid towards the middle liquid guide 31. Therefore, the end liquid guide 32 can supply liquid to the middle liquid guide 31, reducing the problem of insufficient liquid supply to the middle liquid guide 31 and thus causing partial dry burning of the heating element 1. In addition, the end liquid guide 32 can keep both ends of the heating element 1 moist, which not only serves as pre-wetting but also assists in supplying liquid to the middle liquid guide 31, reducing the occurrence of dry burning. Then, the liquid outlet 211 of the liquid storage space 23 in the tubular support 21 is located in the section of the middle liquid guide 31 directly opposite the tubular support 21, so that the liquid outlet 211 supplies liquid to the middle liquid guide 31. The middle liquid guide 31 can be used as the main liquid supply component, and the end liquid guide 32 can be used as the auxiliary liquid supply component. The liquid storage space 23 stores atomizing liquid, which can ensure sufficient liquid supply to the middle liquid guide 31 and reduce the problem of local dry burning of the heating element 1 due to insufficient local liquid supply to the middle liquid guide 31.

[0046] The power supply assembly may include a control board and a battery cell 8, both of which are electrically connected to the control board.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
