Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The first embodiment is as follows:
referring to figure 1, the utility model discloses an electronic cigarette holder, it is including cigarette holder body 1, and 1 inner chamber of cigarette holder body is formed with the air flue 11 that is used for admitting air, giving vent to anger and is used for storing the oil storage storehouse cavity 12 of tobacco tar, and the design of cigarette holder body 1 and air flue 11 and oil storage storehouse cavity 12 is husky sweat integrated into one piece, and the manufacturing degree of difficulty reduces, can reduce manufacturing cost simultaneously.
The cigarette holder body 1, the air passage 11 and the oil storage chamber cavity 12 are made of PCTG, PC, ABS, PP, PE, POM or PBT materials, preferably PCTG material, the PCTG is transparent plastic and is amorphous copolyester, and a common comonomer used for the PCTG is 1, 4-Cyclohexanedimethanol (CHDM), which is fully called polyethylene Terephthalate-1, 4-cyclohexanedimethanol (Poly (1, 4-Cyclohexylene dimethyl Terephthalate Glycol)). The polyester film is a product obtained by Polycondensation of Terephthalic Acid (PTA), ethylene Glycol (EG) and 1, 4-Cyclohexanedimethanol (CHDM) through an ester exchange method, has good toughness and impact strength, excellent low-temperature toughness, high tear resistance, good processability, excellent chemical resistance, transparency and no bisphenol A.
Referring to fig. 1, a compact protective coating 2 is arranged on the outer wall of the cigarette holder body 1, the surface of the air flue 11 and the inner wall of the oil storage cavity 12. The protective coating 2 is a metal oxide thin film. In this embodiment, the metal oxide film is aluminum oxide (Al) 2 O 3 ) Or titanium oxide (TiO) 2 ) Any one of the single-layer protective films.
A metal oxide thin film is formed on the inner cavity and outer wall surface of the mouthpiece by a low temperature Atomic Layer Deposition (ALD) technique. Firstly, the moisture in the plastic cigarette holder body 1 is reduced by adopting a baking method, and the plastic cigarette holder body 1 is baked for 24 hours at the temperature of 60-100 ℃ to fully remove the moisture adsorbed in the cigarette holder body 1. And then the dried cigarette holder body 1 device is placed in a deposition chamber, vacuum pumping is carried out, and then the surface of the cigarette holder body 1 is cleaned by plasma glow, so that pollutants on the surface are effectively removed, the surface performance of the material is improved, and the adhesive force of the coating is improved. In a metal oxide deposition process, two or more gaseous precursors are filled into a vacuum-sealed deposition chamber and react on the substrate surface, producing a solid thin film. Because the precursors are gas-phase molecules, they fill all the space of the deposition chamber, and do not depend on the geometry of the substrate, the chemical adsorption of the substrate surface (the cigarette holder body 1, the air passage 11 and the oil storage chamber cavity 12) to the precursors provides strong adhesion, and the chemical reaction and growth controlled by the surface realize uniform film deposition. In order to avoid the two gaseous precursors with different chemical properties from generating space reaction to form powder and generate structural defects, only one gaseous precursor is introduced into the deposition chamber every time, then the gas extraction is stopped for a moment, and the precursors are fully diffused and adsorbed in the deposition chamber and even penetrate into micropores and cracks on the surface of the base material to seal the micropores and cracks. At this point, the pumping valve is again opened to pump away the residual precursor in the deposition chamber. The next step is to introduce another gaseous precursor in the same way and so on. Thus, the growth of the metal oxide thin film is surface controlled, the introduction of each precursor is not continuous, but pulsed, and the thin film is grown layer by layer on the substrate surface to form a conformal, nanoscale defect-free dense structure. The pulse time of the precursor introduction, as well as the time interval between pulses, can be precisely adjusted and controlled by a computer program.
Referring to figure 1, the growth temperature of the protective coating 2 can be as low as 60 ℃, and therefore has no adverse effect on the structure of the mouthpiece body 1, the air duct 11 and the reservoir cavity 12. The thickness of the metal oxide film is generally controlled within the range of 10-100 nanometers, and the size and the appearance of the cigarette holder body 1, the air passage 11 and the oil storage chamber cavity 12 are not influenced. According to actual needs, the material can be aluminum oxide (Al) 2 O 3 ) Or titanium oxide (TiO) 2 ) A monolayer film. The compact oxide films seal the structural defects of the outer wall of the cigarette holder body 1, the surface of the air flue 11 and the inner cavity surface of the oil storage bin cavity 12, can serve as a barrier layer and a protective layer, and obviously improve the heat resistance, moisture resistance, chemical reaction resistance and corrosion resistance of the cigarette holder body 1, the air flue 11 and the oil storage bin cavity 12.
Alumina (Al) 2 O 3 ) The film has a very stable structure, mainly provides good high temperature resistance and oxidation resistance, and can further reduce the Water Vapor Transmission Rate (WVTR) and the Oxygen Transmission Rate (OTR) of the plastic because all micro-defects are sealed. Meanwhile, alumina (Al) 2 O 3 ) The film has good bonding force with the cigarette holder body 1, the air passage 11 and the oil storage chamber cavity 12. The water vapor transmission rate and the oxygen transmission rate are reduced by at least one order of magnitude compared to the water vapor transmission rate and the oxygen transmission rate without the protective coating.
The ALD film can achieve near zero defect density, can 100% coat a high aspect ratio (aspect ratio) three-dimensional structure, and has a low film-forming temperature. Many metal oxide films (e.g. Al) 2 O 3 ) Can form film at 60 deg.c and is compatible with organic plastic in production process.
ALD has outstanding coating film homogeneity and shape keeping nature, can be effectively at the outer wall of cigarette holder body 1, the even film-forming of air flue 11 surface and oil storage bin cavity 12 inner chamber, does not drop, and this is incomparable with other coating techniques. Due to aluminum oxide (Al) 2 O 3 ) The film has excellent compactness and can serve as a blocking layer, so that chemical reaction between tobacco tar and plastic in the cigarette holder body 1, the air passage 11 and the oil storage bin cavity 12 is effectively prevented, the problems of adsorption and permeation of spice in the tobacco tar on the plastic are reduced, and the taste loss of the tobacco tar is reduced. The oxide coating itself is also harmless to the human body.
ALD alumina (Al) 2 O 3 ) The film can effectively improve the thermal stability of the cigarette holder body 1 by 20-50%, and the cigarette holder can reduce the problems of peculiar smell, toxic gas release and the like caused by heating of the electronic cigarette, so that a smoker can have better taste and harm to the body is reduced.
Example two:
referring to fig. 2, the distinguishing features from the first embodiment are: the metal oxide film is aluminum oxide (Al) 2 O 3 ) And titanium oxide (TiO) 2 ) The double-layer film or the multilayer film with more than two layers is formed, and the effect of the protective coating 2 with more than two layers is better than that of the single-layer film.
Example three:
referring to fig. 3, the distinguishing features from the first embodiment are: the metal oxide film is aluminum oxide (Al) 2 O 3 ) And titanium oxide (TiO) 2 ) The mixed monolayer film is a monolayer film, but two different metal oxides are mixedThe effect of the protective film of the compound is better than that of the single metal oxide.
The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
