Problems solved by technology

[0002] In the existing porous ceramic atomizing core, the e-liquid in the oil storage tank impregnates to the atomizing surface through the ceramic pores under the action of the pressure difference, and the formation of the pressure difference requires setting a pneumatic structure on the atomizing core to communicate with the external environment , and the pressure difference must be kept stable to ensure the continuous and stable impregnation of the e-liquid. On the one hand, this structure increases the difficulty in the preparation of the atomizing core. It is inevitable that there will be relatively large fluctuations in the pressure difference, so that the e-liquid cannot be stably infiltrated into the atomizing surface, and cannot provide enough e-liquid to the atomizing surface in time, resulting in a small amount of e-cigarette atomization and poor user experience.

preparation example Construction

[0024] Such as figure 1 As shown, the preparation method of the porous ceramic atomizing core of this embodiment includes the following steps:

[0025] S1. Provide porous ceramics: provide porous ceramics for preparing atomizing cores. The preparation method of the porous ceramics is as follows:

[0026] S1.1. Surface modification of ceramic powder: After mixing the ceramic powder and the surface modifier, they are pretreated by ball milling together to obtain surface-modified ceramic powder.

[0027] Specifically, in this embodiment, natural microporous diatomite, mica or medical stone is used as the ceramic powder, and the particle size of the ceramic powder is 15 μm. After the ceramic powder is mixed with the surface modifier, ball milling pretreatment is carried out together to form a coating layer on the surface of the ceramic powder, and the surface modified ceramic powder is obtained after drying. The mass ratio of the ceramic powder to the surface modifier is 100:1, ...

Embodiment 2

[0046] Embodiment 2: The preparation method of the porous ceramic atomizing core of this embodiment, in order to make the porous ceramic atomizing core have a better lipophilic effect, in addition to the specific steps in Example 1, the following steps may also be included:

[0047] S3. Coating coupling agent: prepare a mixed solution of coupling agent and ethanol, and fully stir it to make it evenly mixed. The volume ratio of coupling agent and ethanol in the mixed solution is 2 to 5:100. The coupling agent is a silane coupling agent; soak the porous ceramic atomizing core covered with a nanoparticle layer into the mixed solution for 12-24 hours; take it out, wash it, and carry out drying treatment. The range is 80-110° C., the drying treatment time is 0.5-5 hours, and the porous ceramic atomizing core with the coupling agent adsorbed is obtained.

[0048] The coupling agent includes γ-aminopropyltriethoxysilane, γ-(2,3-epoxypropoxy)propyltrimethoxysilane, γ-(methacryloyloxy)...

Embodiment 3

[0051] Embodiment 3: The preparation method of the porous ceramic atomizing core of this embodiment, in order to make the adsorbed coupling agent more tightly bonded to the porous ceramic, in addition to the specific steps in Embodiment 2, the following steps may also be included:

[0052] S4. Preparation of a nano-film layer: the surface of the porous ceramic atomizing core adsorbed with a coupling agent is coated with a nano-film layer by low-temperature deposition (ALD), and the nano-film layer includes at least one of SiO2, Al2O3 or ZnO.

[0053] The preparation of the nano-film layer can stabilize the adsorbed coupling agent and reduce the possibility of its desorption on the porous ceramic surface. At the same time, it can also improve the lipophilicity of the atomizing core, making it easier for the e-liquid to penetrate.

[0054] In the most optimal embodiment of the preparation method of the porous ceramic atomizing core of the present invention, the surface of the por...
