Referring to fig. 3 to 5, fig. 3 is a schematic structural view of the first embodiment of the heating element according to the present application, wherein fig. 4 is a schematic structural view of the heating element according to fig. 3, and fig. 5 is a schematic sectional structural view of the heating element according to fig. 3 taken along line A-A.
The heating element 11 includes a base 111, and the base 111 has an atomizing surface 1111 and a liquid absorbing surface 1112 which are disposed opposite to each other. The base 111 is provided with a first liquid-guiding hole 1113, and the first liquid-guiding hole 1113 penetrates the atomizing surface 1111 and the liquid-absorbing surface 1112. The atomizing surface 1111 has a protrusion 1114, and the protrusion 1114 is disposed corresponding to the first liquid guiding hole 1113; the first fluid transfer hole 1113 penetrates the boss 1114. By providing the projection 1114 on the atomizing surface 1111, the surface area of the atomizing surface 1111 is increased, and thus the atomizing area is increased, which is advantageous for improving the atomizing efficiency of the heating element 11.
In one embodiment, the base 111 is provided with a plurality of first liquid guiding holes 1113, the atomizing surface 1111 has a plurality of mutually spaced protrusions 1114, and one protrusion 1114 is disposed corresponding to at least one first liquid guiding hole 1113. The base 111 further has a plurality of second liquid guiding holes 1115, the second liquid guiding holes 1115 penetrate through the atomizing surface 1111 and the liquid absorbing surface 1112, and projections of the second liquid guiding holes 1115 and the protruding portions 1114 on the liquid absorbing surface 1112 are offset. The plurality of second fluid conduction holes 1115 communicate through gaps 1114d between adjacent bosses 1114; in other words, the plurality of second fluid conduction holes 1115 communicate by capillary action between adjacent bosses 1114.
Wherein, the surface of the bulge 1114 far away from the liquid suction surface 1112 protrudes from the port of the second liquid guide hole 1115 far away from the liquid suction surface 1112; that is, the surface of the protrusion 1114 away from the liquid suction surface 1112 is higher than the port of the second liquid guide hole 1115 away from the liquid suction surface 1112.
A portion of the aerosol-generating substrate on the liquid suction surface 1112 reaches the atomizing surface 1111 through the second liquid guiding holes 1115, the plurality of second liquid guiding holes 1115 communicate by capillary action between adjacent bosses 1114, and the portion of the aerosol-generating substrate is locked in the gaps 1114d between the adjacent bosses 1114; the aerosol-generating substrate guided through the second liquid guiding holes 1115 is heat atomized in the gaps 1114d between the projections 1114. Because the port of the second liquid guiding hole 1115 far away from the liquid suction surface 1112 is lower than the surface of the protruding part 1114 far away from the liquid suction surface 1112, the port of the second liquid guiding hole 1115 far away from the liquid suction surface 1112 is easy to be covered by an oil film, that is, the gap 1114d between the protruding parts 1114 is easy to be covered by the oil film, the liquid film surrounds the protruding parts 1114, so that the protruding parts 1114 can be prevented from being overheated, and larger boiling bubbles can be formed during atomization.
Another portion of the aerosol-generating substrate on the liquid suction surface 1112 reaches the surface of the boss 1114 through the first liquid-guiding hole 1113; the aerosol-generating substrate guided through the first liquid guiding aperture 1113 is heated to atomize at the surface of the boss 1114. Because the surface of the protruding part 1114 far away from the liquid suction surface 1112 protrudes out of the port of the second liquid guide hole 1115 far away from the liquid suction surface 1112, an oil film is not easy to form on the surface of the protruding part 1114 far away from the liquid suction surface 1112, and the atomization mode is an in-hole steam explosion mode.
The surface of the raised portion 1114 and the gap 1114d between adjacent raised portions 1114 may simultaneously heat the aerosol-generating substrate to be atomized, the provision of the raised portions 1114 increasing the area of atomization, thereby improving the efficiency and amount of atomization. And the surface of the protrusion 1114 is different from the atomization condition of the gap 1114d between the adjacent protrusions 1114, which is beneficial to the atomization of different boiling point substances in the aerosol generating substrate and improves the taste.
Alternatively, the axis of the first liquid guiding hole 1113 is perpendicular to the liquid suction surface 1112, i.e., the axis of the first liquid guiding hole 1113 is parallel to the thickness direction of the base 111.
Optionally, the axis of the second liquid guiding hole 1115 is perpendicular to the liquid suction surface 1112, i.e., the axis of the second liquid guiding hole 1115 is parallel to the thickness direction of the base 111.
To avoid over-heating of the boss 1114, the boss 1114 may alternatively have an equivalent diameter of 1 μm to 100 μm.
In order to have sufficient capillary force to lock the liquid film and sufficient space to store the liquid, the gap width between adjacent bosses 1114 may be, optionally, 40 μm to 200 μm.
Optionally, one protruding portion 1114 is disposed corresponding to the plurality of first liquid guiding holes 1113. Illustratively, one boss 1114 is disposed corresponding to five first fluid transfer holes 1113, with the axis of one fluid transfer hole 1113 coinciding with the axis of the boss 1114, defining it as a central hole, and the other fluid transfer holes 1113 being circumferentially spaced around the central hole; alternatively, the other fluid transfer holes 1113 are centrally and symmetrically disposed along the central hole (as shown in FIGS. 3-5).
