Problems solved by technology

However, the quality of the film at this thickness is bound to be affected by the surface roughness of the porous ceramic.
[0006] Fourth, other similar atomizing cores: such as CN201620757596.4, CN201810009220.9 and CN201910229470.8 announced MEMS atomizing cores based on silicon single crystals, hoping to solve the problem of uniformity of atomization temperature and direct contact between the heating surface and the smoke liquid The taste changes, the microhole array is used as a micro-orifice plate to control the liquid flow, the diameter of the microfluidic channel is 10 to 500 microns, the diameter of the micropore channel is 500 to 1000 microns, and the metal film used is Ti / Pt / Au with a thickness of 200 to 500nm , TiW / Au, Al, Cr or Pt / Au, but there are still some problems in the system reliability of this device
[0007] From the perspective of safety, although the above four atomization methods have greatly reduced the harmful components in traditional cigarettes, there are still certain traces of toxic and harmful substances

Embodiment 1

[0034] The substrate is made of alumina single crystal material. After numerical control processing into dimensions, the zoom laser is used to gradually form hole arrays on the substrate. The hole diameters are 120 microns, 100 microns, 80 microns and 60 microns, and the hole wall spacing is controlled separately. At 250 microns, 200 microns, 150 microns, and 100 microns, the array of holes can be arranged in a triangular close-packed arrangement, or in a matrix or other shape. Thereafter, a titanium oxide film or a tantalum oxide film with a thickness ranging from 0.35 microns to 5 microns is formed by sputtering or electron beam evaporation figure 1 The titanium oxide film is 4.5 microns in the middle), and the thickness is directly related to the oxygen component in the film. According to different oxygen content designs, a passivation film is covered on the surface of the film with low oxygen content, such as a gold film of about 12 nanometers (such as the attached figure...

[0036] The substrate is made of alumina single crystal material. After numerical control machining into dimensions, the zoom laser is used to gradually form a hole array on the substrate. The diameter of the holes is 100 microns, and the distance between the hole walls is controlled at 200 microns. The hole arrays are closely packed in triangles. Arrangements can also be arranged in a matrix or other shapes. Thereafter, a titanium oxide film or a tantalum oxide film with a thickness ranging from 0.35 microns to 5 microns is formed by sputtering or electron beam evaporation figure 2 The titanium oxide film is 4 microns in the middle), and the thickness is directly related to the oxygen component in the film.

Embodiment 3

[0038] The substrate is made of transparent quartz glass. After numerical control processing into dimensions, a zoom laser is used to gradually form a hole array on the substrate. Arrays are arranged in a triangular close-pack, but can also be arranged in a matrix or other shape. Thereafter, a layer of titanium oxide film or tantalum oxide film with a thickness ranging from 0.35 microns to 5 microns is formed by sputtering or electron beam evaporation, and the thickness is directly related to the oxygen component in the film. According to the design of different oxygen content, the surface of the film with low oxygen content is covered with a passivation film, such as a gold film of about 15 nanometers, and then electrodes are formed with safe conductive paste at both ends and connected to the battery. The thin film deposited between the hole walls forms a uniform temperature field and nucleation center, and forms a controllable liquid flow and air flow channel during the atom...

Abstract

The invention belongs to the field of atomization application, and discloses a novel atomizing core. The novel atomizing core comprises an atomizing core base plate and a heating body on the atomizingcore base plate, the atomizing core base plate is made of compact materials, oil guide holes are distributed in the atomizing core base plate, the diameter of each oil guide hole is 1-250 micrometers, the wall distance between every two adjacent oil guide holes is 500 micrometers or below, and the porosity of compact ceramic is lower than 30%. According to the novel atomizing core, the controllable liquid flow channel is formed in the base plate, in the heating atomization process, approximate in-situ atomization can be achieved, the liquid flow channel is quantified, and the fluid flow is accurately controlled, so that the quantum atomization effect is achieved, the nucleation and particle growth processes of atomized particles are controlled to the maximum extent, and the purpose of uniform atomization is achieved. Meanwhile, ceramic powder and relatively toxic and harmful substances are prevented from entering atomized aerosol due to a porous ceramic process, so that safer quantitative atomization is provided.

Description

technical field [0001] The invention relates to the field of atomization application, in particular to a novel atomization core. Background technique [0002] At present, the commonly used atomization method for electronic cigarettes and some medical atomizers is to atomize the liquid through resistance heating to form an aerosol, which is mainly divided into the following four types: [0003] One is glass fiber rope plus heating wire: the most common pod vape vaporizer generally winds the resistance wire for heating on the fiber rope used for liquid conduction, and the glass fiber rope is used as the main oil guide material because glass fiber The rope has the characteristics of strong selvedge, high temperature resistance, strong oil absorption, and fast oil conduction speed; while the biggest disadvantage of glass fiber oil guide rope is that it is prone to shedding and floc. In addition, the position of the heating wire is fixed and when the heating wire is wrapped arou...
