Referring to fig. 1 to 9, the present invention provides an atomizing assembly 100 for heating an atomized substrate, where the atomizing assembly 100 includes a ceramic substrate 110 and a heating element 120, the ceramic substrate 110 includes an atomizing surface 113, the heating element 120 is mounted on the atomizing surface 113, the heating element 120 at least includes a first heating element 121 and a second heating element 122, and the first heating element 121 and the second heating element 122 are arranged on the atomizing surface 113 at intervals.

The ceramic base 110 is provided with at least a first oil guiding groove 111 and a second oil guiding groove 112 on a side departing from the atomizing surface 113, that is, the top of the ceramic base 110 is provided with the first oil guiding groove 111 and the second oil guiding groove 112, the first oil guiding groove 111 and the second oil guiding groove 112 are arranged to depart from the atomizing surface 113, wherein the first oil guiding groove 111 is arranged corresponding to the second heat generating component 122, the second oil guiding groove 112 is arranged corresponding to the second heat generating component 122, the size of the first oil guiding groove 111 is adapted to the size of the first heat generating component 121, the size of the second oil guiding groove 112 is adapted to the size of the second heat generating component 122, the smoke liquid is transmitted and transported to the first heat generating component 121 by the bottom of the first oil guiding groove 111, and the smoke liquid is transmitted and transported to the second heat generating component 122 by the bottom of the second oil guiding groove 112, the first heating element 121 and the second heating element 122 heat to atomize the smoke liquid, and the first heating element 121 and the second heating element 122 are arranged at intervals and in a staggered manner, so that the heating element 120 is prevented from generating heat intensively.

It should be noted that, because the heating element 120 is not disposed between the first oil guiding groove 111 and the second oil guiding groove 112, a partition fence may be further disposed between the first oil guiding groove 111 and the second oil guiding groove 112, and the partition fence partitions the first oil guiding groove 111 and the second oil guiding groove 112, and because the ceramic substrate 110 is thicker at the partition fence, the phenomenon that smoke liquid drops due to the fact that smoke liquid cannot be atomized by the heating element 120 due to permeation and transmission between the first oil guiding groove 111 and the second oil guiding groove 112 is avoided. In general, the atomizing surface 113 of the ceramic substrate 110 is sealed at a place where the heating element 120 is not disposed, for example, the atomizing surface can be sealed by a silica gel member or an oxidized glaze ceramic member, so as to avoid the phenomenon that the smoke liquid is transmitted to a blank area between the first heating element 121 and the second heating element 122 and cannot be atomized and then collected and dripped, thereby ensuring the normal use of the atomizing assembly 100.

It is understood that the heat generating body 120 may include a plurality of heat generating members.

In this embodiment, the heating element 120 further includes two electrodes 124, the two electrodes 124 are disposed on the atomizing surface 113, the two electrodes 124 are respectively used as the positive electrode or the negative electrode of the heating element 120, the electrodes 124 may be conductive wafers or conductive columns, the first heating element 121 and the second heating element 122 are heating wires, the heating wires are disposed in a sheet shape, conductive sheets 123 are disposed at two opposite ends of the first heating element 121, and conductive sheets 123 are disposed at two opposite ends of the second heating element 122, wherein the width of the conductive sheets 123 is greater than the width of the heating wires, that is, the resistance on the conductive sheets 123 is small, and the heating value of the conductive sheets 123 is negligible. The two opposite ends of the first heating element 121 are separately connected to the two electrodes 124 through conductive strips 123, and the two opposite ends of the second heating element 122 are separately connected to the two electrodes 124 through conductive strips 123, so that the first heating element 121 and the second heating element 122 are connected in parallel.
