The width of the clamping groove 502 is smaller than the sum of the thickness of the first oil guide 42, the thickness of the second oil guide 44 and the thickness of the first electric connection sheet 16 and the thickness of the second electric connection sheet 18, so that pressure can be generated between the groove wall on one side of the clamping groove 502 and the first oil guide 42, and pressure can be generated between the groove wall on the other side of the clamping groove 502 and the second oil guide 44, so that the groove wall of the clamping groove 502 can clamp the first oil guide 42 and the second oil guide 44, and the first oil guide 42 and the second oil guide 44 clamp the first electric connection sheet 16 and the second electric connection sheet 18, and the first electric connection sheet 16 and the second electric connection sheet 18 can be well electrically connected.

Through the structure, the heating component 10 and the oil guide component 40 are bent into a cylinder, the first electric connection piece 16 is contacted with the second electric connection piece 18, and then the heating component 10 can encircle to be 360 degrees, so that a 360-degree annular heating surface is formed, the heating atomization area is increased, the uniformity of smoke oil atomization is improved, and burning is prevented. The groove wall of the clamping groove 502 clamps the first oil guide 42 and the second oil guide 44, the first oil guide 42 presses the first electric connecting sheet 16 inwards, the second oil guide 44 presses the second electric connecting sheet 18 inwards, and the first electric connecting sheet 16 is contacted with the second electric connecting sheet 18; the first oil guide 42 and the second oil guide 44 can be abutted against the groove wall of the clamping groove 502, so that relative axial sliding is not easy to occur between the heating component 10 and the oil guide component 40 and between the oil guide component 40 and the mounting pipe component 50, and meanwhile, relative circumferential rotation is also difficult to occur, and finally, the stability of the heating assembly 100 in the embodiment is improved.

Referring back to fig. 3, in some embodiments, a first anti-slip hole 1602 is formed on the first electrical connection piece 16, a second anti-slip hole 1802 is formed on the second electrical connection piece 18, and the oil guiding component 40 is made of a flexible material; the first oil guide 42 partially extends into the first non-slip aperture 1602 and the second oil guide 44 partially extends into the second non-slip aperture 1802.

Specifically, in the present embodiment, the first anti-slip holes 1602 are circular through holes, three first anti-slip holes 1602 are formed on one first electric connection sheet 16, the second anti-slip holes 1802 have the same structure as the first anti-slip holes 1602, and three second anti-slip holes 1802 are also formed on one second electric connection sheet 18.

In other embodiments, the first non-slip holes 1602 may have other shapes, such as rectangular or diamond shapes, and one first connecting piece 16 may have other numbers of first non-slip holes 1602, such as one or two first non-slip holes; the shape of the second non-slip apertures 1802 may also be different from the shape of the first non-slip apertures 1602, for example, the first non-slip apertures 1602 may be rectangular and the second non-slip apertures 1802 may be circular. The first non-slip holes 1602 may not be through holes, and the first non-slip holes 1602 may be formed on the surface of the first electric connection piece 16 that is attached to the first oil guiding member 42.

Through the above structure, when the flexible first oil guiding element 42 is tightly attached to the first electric connecting sheet 16, pressure is applied between the first oil guiding element 42 and the first electric connecting sheet 16, so that the first oil guiding element 42 can deform and partially extend into the first anti-slip hole 1602, and the part of the first oil guiding element 42 extending into the first anti-slip hole 1602 is more difficult to relatively slide between the first oil guiding element 42 and the first electric connecting sheet 16 under the action of the pressing action of the wall of the first anti-slip hole 1602 and the part of the first oil guiding element 42 extending into the first anti-slip hole 1602; similarly, the second oil guide 44 and the second electric connection piece 18 are more difficult to slide relatively; eventually, the stability of the heating assembly 100 in this embodiment is improved.

In some embodiments, the first anti-skid holes 1602 and the second anti-skid holes 1802 are through holes; the first anti-skid hole 1602 communicates with the second anti-skid hole 1802.

Specifically, the first electrical connection piece 16 has the same structure as the second electrical connection piece 18, and the first anti-slip holes 1602 and the second anti-slip holes 1802 have the same structure, one surface of the first electrical connection piece 16 overlaps one surface of the second electrical connection piece 18, each first anti-slip hole 1602 is coaxially disposed with the corresponding second anti-slip hole 1802, and each first anti-slip hole 1602 is further communicated with the corresponding second anti-slip hole 1802.

In some embodiments, the first non-slip apertures 1602 include at least two, the first non-slip apertures 1602 are aligned in a row in a direction away from the first heat generating network 12, and the second non-slip apertures 1802 are in one-to-one correspondence with the first non-slip apertures 1602; each first non-slip aperture 1602 communicates with a corresponding one of the second non-slip apertures 1802.

Specifically, in the present embodiment, the first anti-slip holes 1602 and the second anti-slip holes 1802 include three first anti-slip holes 1602, and the three first anti-slip holes 1602 are linearly arranged along a direction away from the first heat generating network 12, and the intervals between two adjacent first anti-slip holes 1602 are equal. In other embodiments, the first non-slip apertures 1602 may include other numbers, such as two or four, and the first non-slip apertures 1602 may be arranged in other arrangements, such as all of the first non-slip apertures 1602 disposed around a single point. The first anti-slip holes 1602 include three, and the intervals between two adjacent first anti-slip holes 1602 are equal.

Through the above structure, each first anti-slip hole 1602 can be used for the first oil guiding piece 42 to extend into, and each second anti-slip hole 1802 can be used for the second oil guiding piece 44 to extend into, so that the hole walls of at least two first anti-slip holes 1602 can simultaneously provide resistance for the first oil guiding piece 42, and the hole walls of at least two second anti-slip holes 1802 can simultaneously provide resistance for the second oil guiding piece 44, so that the heat generating component 10 is further difficult to slide relative to the oil guiding component 40.

When first oil guide 42 has a sliding tendency with respect to first electric connection piece 16 in a direction away from first heat generating network 12, because first anti-slip holes 1602 are aligned, and thus forces between the walls of all first anti-slip holes 1602 and first oil guide 42 are collinear in a direction perpendicular to the central axis of mounting tube member 50, first oil guide 42 is more difficult to slide with respect to first electric connection piece 16; it is similarly possible to make the second oil guide 44 more difficult to slide with respect to the second electrical connection piece 18.

In some embodiments, the first electrical connection pads 16 include at least two, with a gap formed between two adjacent first electrical connection pads 16, and the second electrical connection pads 18 are in one-to-one correspondence with the first electrical connection pads 16, and each first electrical connection pad 16 is in engagement with a corresponding second electrical connection pad 18.

Specifically, in this embodiment, first electrical connection tab 16 includes two and second electrical connection tab 18 includes two, and first non-slip aperture 1602 on first electrical connection tab 16 communicates with second non-slip aperture 1802 on corresponding second electrical connection tab 18. In other embodiments, the first electrical connection pad 16 may also include other numbers, such as three or four.
