Electronic cigarette atomizer porous ceramic, preparation method thereof, and electronic cigarettes provided with electronic cigarette atomizer porous ceramic

Abstract

The invention discloses an electronic cigarette atomizer porous ceramic, a preparation method thereof, and electronic cigarette provided with the electronic cigarette atomizer porous ceramic, and belongs to the field of electronic cigarette. The electronic cigarette atomizer porous ceramic comprises, by mass, 50 to 80 parts of diatomite, 5.35 to 12.2 parts of boron oxide, and 2.15 to 9.8 parts ofaluminium dihydrogen phosphate. According to the preparation method, adding of boron oxide and aluminium dihydrogen phosphate is capable of increasing porous ceramic compressive strength. The preparation method comprises following steps: diatomite and a pore forming agent are mixed; blank material blocks are prepared; a porous ceramic skeleton prefabricated body is prepared through sintering; theporous ceramic skeleton prefabricated body is crushed; a porous ceramic powder is prepared; a pug is prepared; moulding of porous ceramic oil guide rods is carried out; semi-finished porous ceramic sintering is carried out; and the surface of semi-finished porous ceramic is coated with a silane coupling agent so as to obtain a finished product. The preparation method is capable of realizing uniform distribution of pores in the porous ceramic, and improving oil absorption and oil locking capacity; and the electronic cigarette provided with the electronic cigarette atomizer porous ceramic are capable of providing consumers with good experience feeling.

Description

technical field [0001] The present invention relates to the field of electronic cigarettes, more specifically, it relates to a porous ceramic for an electronic cigarette atomizer, a preparation method thereof, and an electronic cigarette with the porous ceramic for an electronic cigarette atomizer. Background technique [0002] E-cigarettes are a new type of product that uses a rechargeable lithium polymer battery to drive an atomizer, and generates smoke by heating the e-liquid in the "drug pod", which replaces traditional cigarettes. E-cigarettes are less harmful to the human body than traditional cigarettes. E-cigarettes do not involve any open flames in the process of generating smoke, and there are no hundreds of harmful substances such as tar produced by traditional cigarettes. [0003] The atomizer is the core component of the electronic cigarette. The current mainstream structure is to use glass fiber rope as the oil-conducting medium, and a heating resistance wire i...

Problems solved by technology

[0005] However, porous ceramics used as smoke oil absorbers generally require a higher oil absorption rate of the porous ceramics, so that the smoke produced by atomization will be more

However, after the ceramic has a large porosity and a larger pore size, first, the strength will deteriorate, and fine particles will easily fall off the ceramic body. If it is inhaled into the mouth, it will seriously affect the experience of using the electronic cigarette.

The second is that the pore size distribution is often uncontrollable. After the oil absorption rate increases, the oil locking ability will decrease, and oil leakage is prone to occur, which will cause liquid e-liquid to enter the mouth of the smoker, affecting the taste and experience

If the porosity is too small, the oil conductivity will decrease, the amount of smoke will decrease, which will also affect the experience, and the wettability of the e-liquid to porous ceramics is not good enough, which will also affect the oil absorption speed
