Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present utility model more apparent.
As shown in fig. 1, the utility model provides a porous ceramic atomization core, which comprises a porous ceramic matrix 1 and a metal heating layer 2 covered on the top of the porous ceramic matrix 1, wherein a groove 3 is arranged on the top of the porous ceramic matrix 2. The design of recess 3 can further increase porous ceramic base member 1 and metal layer 2 that generates heat area, when guaranteeing the combination compactness of metal film and porous ceramic base member, is favorable to improving the heating effect, and heating rate is faster and hotter more even, and then makes the atomizing core produce a large amount of smog.
Specifically, at least two grooves 3 are provided along the length direction or the width direction of the porous ceramic substrate 1.
In order to increase the bonding uniformity of the porous ceramic substrate 1 and the metal heating layer 2, the grooves 3 are uniformly arranged on the surface of the porous ceramic substrate 1, so that the situation of uneven bonding force in different areas can be avoided.
As shown in fig. 2, the shape of the recess 3 may be a cylinder or a prism. The groove 3 has simple shape and convenient design, and the material of the metal heating layer 2 can be tightly combined with the porous ceramic matrix 1 after being heated and expanded, so that the metal heating layer is not easy to fall off.
As shown in fig. 3, the shape of the recess 3 may be a truncated cone or a trapezoidal cone. By adopting the structure with the narrow upper part and the wide lower part, the metal heating layer 2 is firmly fixed in the groove after being heated and expanded, and the combination firmness of the metal heating layer and the porous ceramic matrix 1 can be further ensured.
As shown in fig. 4, the shape of the groove 3 may be a combination of a cylinder and a truncated cone or a combination of a prism and a trapezoidal cone. The combination of the various shapes can further increase the contact area of the metal heat generating layer 2 and the porous ceramic substrate 1, thereby further increasing the bonding tightness of the two.
The paste used for the metal heating layer is generally composed of noble metals such as gold, silver, platinum, palladium and the like and low-melting-point glass. The porous ceramic matrix 1 may be obtained by additive forming, so that the shape of the grooves 3 may not be limited by conventional pressing processes, and thus different shapes of the grooves 3 may be designed.
In order to further improve the bonding capability of the porous ceramic substrate and the porous ceramic substrate, the area of the groove 3 is 1/3-3/5 of the area of the top of the porous ceramic substrate 1. If the area of the groove is too small, the metal heating layer 2 cannot be tightly combined with the porous ceramic matrix 1; if the area of the grooves is too large, the strength of the porous ceramic matrix may be adversely affected.
The depth of the groove 3 is 1/7-1/12 of the height of the porous ceramic matrix 1. If the depth of the groove 3 is too small, the function of enhancing the combination force of the porous ceramic matrix 1 and the metal heating layer 2 can not be achieved; if the depth of the grooves 3 is too large, the liquid absorbing ability of the porous ceramic substrate 1 is lowered.
The thickness of the metal heating layer 2 is 1/8-1/5 of the height of the porous ceramic matrix 1. If the thickness of the metal heating layer 2 is too small, the effect of uniformly heating the liquid cannot be achieved; if the thickness of the metal heat generating layer 2 is too large, waste is caused.
In order to further improve the use effect of the porous ceramic atomizing core, the pore diameter of the porous ceramic matrix 1 is 10-100 mu m, and the porosity of the porous ceramic matrix 1 is more than or equal to 50%. The proper pore size and porosity can improve the liquid absorbing capability of the porous ceramic matrix 1, thereby improving the use experience of users.
While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the utility model, such changes and modifications are also intended to be within the scope of the utility model.
