Embodiment 1

[0040] Embodiment 1, specifically refer to Figure 1-5 , a heating element with a porous ceramic surface embedded with a heating mesh, comprising a ceramic base 1 and a heating mesh 2 embedded in the ceramic base 1, the ceramic base 1 is a ceramic body with a porous structure inside, and the heating mesh The sheet 2 is embedded on the surface of the ceramic base 1. The heating mesh 2 has at least two ends and a wall surface exposed on the surface of the ceramic base 1. The ceramic base 1 and the heating mesh 2 together form a heating body.

[0041]Preferably, the ceramic base 1 includes a base body 11 and a base protrusion 12 extending upward from the base body 11, and the heating mesh 2 includes a first end connection piece 21, a second end connection piece 22, a second end connection piece One side heating sheet 23, the second side heating sheet 24 and the middle connection heating sheet 25;

[0042] The first side heating sheet 23 and the second side heating sheet 24 are b...

Embodiment 2

[0046] Embodiment 2: specific reference Image 6

[0047] This embodiment is basically the same as Embodiment 1, and its difference is that: the upper part of the cross-section of the ceramic base 1 is a trapezoidal structure, the side wall of the upper part of the ceramic base 1 is an inclined wall, and the heating mesh 2 is embedded in the ceramic base 1. On vertical side walls, inclined side walls and horizontal upper walls.

Embodiment 3

[0048] Embodiment 3: specific reference Figure 7

[0049] This embodiment is basically the same as Embodiment 1, except that the upper part of the cross-section of the ceramic base 1 is arc-shaped, and the two sides of the upper part of the ceramic base 1 are inclined walls, and there is an arc between the two inclined walls. The shaped upper wall serves as a transitional surface, and the heating mesh 2 is embedded on the vertical wall, the inclined wall and the arc-shaped transitional upper wall of the ceramic base 1 .

Abstract

The invention discloses a heating body with a heating mesh inlaid on the surface of porous ceramic and a preparation method thereof. The heating body comprises a ceramic substrate and the heating meshinlaid on the ceramic substrate, wherein the ceramic substrate is a ceramic body; the interior of the ceramic body has a porous structure; and the heating mesh is inlaid on the surface of the ceramicsubstrate. The preparation method for the heating body with the heating mesh inlaid on the surface of the porous ceramic comprises the following preparation steps: preparation of materials, i.e., preparation of a ceramic slurry and the heating mesh; hardening molding in a mold cavity; sintering of a green ceramic heating body; and baking of the green ceramic heating body. The heating body with the heating mesh inlaid on the surface of the porous ceramic and the preparation method thereof provided by the invention have the following advantages which are deficient for a conventional product during implementation: stable structure, fast heating speed, uniform temperature distribution, good use experience, insusceptibility to generating deformation and cracking for the heating mesh, long service life, good use economy, etc.

Description

technical field [0001] The invention relates to the field of electronic cigarette heating, in particular to a heating element with a porous ceramic surface embedded with a heating mesh and a preparation method thereof. Background technique [0002] The ceramic heating plate is a safe and reliable electric heating element that heats up after being energized without being charged and has no open flame. The current ceramic heating element is a heating element produced by printing electronic paste directly on the ceramic green body, baking at high temperature and then processing electrodes and leads. However, due to the insufficient heating rate and uneven temperature distribution of the printed circuit (mainly due to the uneven local concentration of the electronic paste when printing the electronic paste, the uneven resistance of the heating circuit) leads to the disconnection of the heating circuit, and the ceramic sheet is at a high temperature. When the temperature is inco...
