The specific structure of the heat generating structure is shown in the following examples.
Referring to fig. 1 to 3, fig. 1 is a schematic diagram illustrating an overall structure of an atomizer according to a first embodiment of the present invention; FIG. 2 is a cross-sectional view of FIG. 1; FIG. 3 is an exploded view of the heat generating structure of the present invention; in an embodiment of the present invention, the heat generating structure includes a ceramic body (300, 400, 500) and a heat generating body 600.
Specifically, the ceramic body (300, 400, 500) is used for guiding liquid, the heating element 600 is in contact with the ceramic body (300, 400, 500) and is used for atomizing the liquid to generate aerosol, the ceramic body (300, 400, 500) is provided with a first side wall for the liquid to enter, and a second side wall far away from the first side wall, and the heating element 600 is fixedly arranged on the second side wall; at least one layer of chambers (420, 520) for storing liquid are formed in the ceramic body (300, 400, 500) and are distributed along the direction from the first side wall to the second side wall in sequence.
In this embodiment, at least one layer of the chamber (420, 520) is formed in the ceramic body (300, 400, 500), and in practical applications, the chamber (420, 520) may be two or more layers. Two or more layers of chambers (420, 520) are arranged overlapping in the direction of the first side wall to the second side wall of the ceramic body (300, 400, 500), i.e. the entire ceramic body (300, 400, 500) is divided into at least two layers, the middle of the two layers being separated by the chambers (420, 520). For a ceramic body (300, 400, 500) having two layers of chambers (420, 520), when the ceramic body (300, 400, 500) is used to guide liquid, the liquid enters from a first side wall of the ceramic body (300, 400, 500), the liquid sequentially passes through the first chamber 420, the chamber wall and the second chamber 520 to enter a second side wall, and finally, aerosol is formed by atomizing a heating body 600 on the second side wall. The first chamber 420 and the second chamber 520 can store a small amount of liquid, and the first side wall, the chamber wall and the second side wall have a filtering function, after the liquid enters the first chamber 420, the surface tension and the viscous force of the liquid can prevent the liquid from entering the second chamber 520, and the two layers of protection can reduce the liquid in the liquid storage bin, so that the liquid leakage caused by the oil pressure generated by gravity or the pressure in the liquid storage bin is higher than the external pressure. The thinner first, chamber and second sidewalls can increase the permeability of the ceramic body (300, 400, 500) and facilitate the channeling of liquids. In addition, because the first side wall, the chamber wall and the second side wall are arranged at intervals, when the heating body 600 on the second side wall heats, the heating effect can be effectively improved by reducing heat conduction loss through the first chamber 420 and the second chamber 520, and meanwhile, the heat conduction to the atomizer can be reduced by liquid in the chamber, so that the problem that the atomizer is overheated and inconvenient to hold is avoided.
Further, at least two layers of chambers (420, 520) are formed in the ceramic body (300, 400, 500) along the direction from the first side wall to the second side wall, each chamber (420, 520) is distributed along the length direction of the ceramic body (300, 400, 500), and at least one supporting structure (410, 510) for supporting the opposite inner walls of the chamber (420, 520) is arranged in each chamber (420, 520).
In this embodiment, the number of the chambers is two or more. The multi-layer chambers are distributed along the direction from the first side wall to the second side wall, i.e. the multi-layer chambers are layered along the direction in which the ceramic body (300, 400, 500) guides the liquid, so that the permeability and oil storage of the ceramic body (300, 400, 500) can be further improved. In view of the structural stability of the ceramic body (300, 400, 500), each chamber of the ceramic body (300, 400, 500) is provided with a support structure (410, 510) to support the opposite inner walls of the chamber (420, 520). The specific structure of the support structure (410, 510) is described in the following embodiments.
