The end of the end cap 40 has limited space, and it is difficult to provide two larger receiving slots 47 in the end cap 40 for receiving the first magnetic coupling members 44. At the same time, the first magnetic coupling member 44 is easily detached from the inside of the housing groove 47, and the atomizer 100 and the power module 200 cannot be magnetically coupled to each other.

In order to stably fix the first magnetic connector 44 to the end cap 40, in some embodiments, as shown in fig. 3 to 6, the first magnetic connector 44 is substantially block-shaped or cylindrical, and is disposed adjacent to the first electrical connector 43, and a blind hole is disposed extending from a bottom surface of the recess 45 of the end cap 40 to an inner portion, and the blind hole defines a receiving cavity 47 forming the first magnetic connector 44.

Wherein, the area of the bottom surface 442 of the first magnetic connector 44 is not smaller than the area of the first surface 4331 of the first electrical connector 43, which facilitates the placement of the first magnetic connector 44. At the same time, since the bottom face 442 of the first electrical connection 43 is substantially hidden by the projection 433 of the first electrical connection 43, only the second surface 4332 of the projection 433 of the first electrical connection 43 is visible to the user from the bottom wall of the end cap 40 of the nebulizer 100, which is more aesthetically pleasing to the user.

In other embodiments, the first magnetic connector 44 has a cross section substantially in the shape of a ring or a semi-ring or a U or other circular arc, at least a portion of the first magnetic connector 44 is disposed around the cylindrical portion 434 of the first electrical connector 43, and at least a portion of the cylindrical portion 434 or the boss 433 of the first electrical connector 43 may be used to support the first magnetic connector 44. It can be understood that when the first magnetic connector 44 is ring-shaped, the first magnetic connector 44 is sleeved on the column portion 434 of the first electrical connector 43, and the bottom surface 442 of the first magnetic connector 44 is disposed near or abutted to the boss 433 of the first electrical connector 43. When the first magnetic connector 44 is a semi-annular or U-shaped, the inner wall surface of the first magnetic connector 44 is close to or abutted against the column portion 434 of the first electrical connector 43, and the bottom surface 442 of the first magnetic connector 44 is close to or abutted against the boss 433 provided on the first electrical connector 43. At least a portion of the securing bore 46 of the end cap 40 defines a receiving cavity 47 for receiving the first magnetic connector 44. The open end 471 of the housing chamber 47 is completely obstructed by the projection 433 of the first electrical connector 43. Only the second surface 4332 of the projection 433 of the first electrical connector 43 is visible to the user from the bottom wall of the end cap 40 of the nebulizer 100.

In some embodiments, the first magnetic connector may be at least partially received in the cavity of the first electrical connector, thereby forming a unitary body and being received in the receiving cavity of the end cap. For example, the first magnetic connector may comprise a metal sheet of ferromagnetic material, which may be annular, as an example, and the annular metal sheet may be fitted on the upper surface of the boss of the first electrical connector or received in an annular groove in the upper surface of the boss.

When the atomizer 100 is connected to the power module 200, referring to fig. 7, the first magnetic connecting piece 44 on the atomizer 100 is magnetically attracted to the second magnetic connecting piece 53 on the power module 200, wherein the first magnetic connecting piece 44 is not in direct contact with the second magnetic connecting piece 53, the boss portion 433 of the first electrical connecting piece 43 is disposed between the two pieces, and the boss portion 433 is also made of a metal material and is thin, so that the magnetic attraction effect between the first magnetic connecting piece 44 and the second magnetic connecting piece 53 is not affected.

5. The nebulizer of claim 1, wherein the first magnetic connector is disposed around at least a portion of a surface of the barrel portion sidewall.

6. A nebulizer as claimed in claim 1, in which the first electrical connection comprises a first positive connection and a first negative connection; the first magnetic connecting piece comprises two magnetic connecting pieces, one of the magnetic connecting pieces is close to the first positive connecting piece, and the other magnetic connecting piece is close to the first negative connecting piece.

7. The atomizer of claim 1, wherein said boss has a planar surface that is substantially flush with an end face of said end cap.

8. A nebulizer as claimed in claim 1, wherein the end cap is provided with a recess for receiving the boss of the first electrical connector; the accommodating cavity is formed by continuously sinking the bottom surface of the sinking part.

9. A nebulizer as claimed in claim 8, wherein the end cap is further provided with a securing aperture for receiving at least part of the barrel portion of the first electrical connector; the fixing hole is communicated with the concave part.

10. An aerosol-generating device comprising an atomiser as claimed in any of claims 1 to 9 and a power supply component magnetically attached to the atomiser and providing electrical drive to the atomiser.

11. An aerosol-generating device comprising an atomiser and a power supply component magnetically attached to the atomiser and providing electrical drive to the atomiser;

the atomizer comprises a first electrical connector for making electrical connection with the power supply component;

the atomizer further comprises a first magnetic connector, and the power supply assembly comprises a second magnetic connector; the first magnetic connecting piece and the second magnetic connecting piece are attracted by magnetic force to provide a combining force for electric conduction between the first electric connecting piece and an electrode of the power supply assembly, and at least part of the first electric connecting piece is arranged between the first magnetic connecting piece and the second magnetic connecting piece.
