The utility model provides an electron cigarette.
Referring to fig. 1 to 4, an electronic cigarette 1 according to the present invention includes a housing 11, an insulating cylinder 12, a heat insulating member 13, and a first nano heat insulating coating 14; the insulating cylinder 12 is arranged in the shell 11, and a heat insulation cavity 121 is formed between the outer wall surface of the insulating cylinder 12 and the inner wall surface of the shell 11 at intervals; the heat insulation piece 13 is arranged in the heat insulation cavity 121; the first nano thermal insulation coating 14 is disposed on the thermal insulation member 13 and/or the insulation cylinder 12.
In the embodiment of the present invention, the shape of the housing 11 is a cylindrical shape, and specifically, the housing 11 may be substantially cylindrical, square cylindrical, polygonal cylindrical, or elliptical cylindrical. The housing 11 may be made of a metal material or a plastic material. The inner wall surface of the housing 11 is a wall surface of the housing 11 close to the insulating cylinder 12, that is, a wall surface of the housing 11 away from the fingers of the user when the user uses the electronic cigarette 1. In order to increase the friction between the housing 11 and the fingers of the user and prevent the electronic cigarette 1 from easily slipping off the hand of the user, the outer wall surface of the housing 11 may be provided with an anti-slip strip, an anti-slip protrusion (e.g., a grinding sand grain), an anti-slip sleeve with a relatively large friction coefficient, or the like, so that the user can feel better when using the electronic cigarette 1.
The insulating cylinder 12 may be substantially cylindrical, square cylindrical, polygonal cylindrical or elliptical cylindrical, so that the insulating cylinder 12 is adapted to the shape of the housing 11, and the insulating effect is good. The outer wall surface of the insulating cylinder 12 is a wall surface of the insulating cylinder 12 close to the housing 11. The insulating cylinder 12 is made of an insulating material, such as insulating varnish, insulating glue, fiber products, rubber, plastic and products thereof, glass, ceramic products, mica, asbestos and products thereof, and the like. The insulating paint and the insulating glue are both based on high molecular polymers and can be cured into an insulating hard film or an insulating whole under certain conditions. The insulating fiber product refers to an insulating material made of insulating paper, paperboard, paper tubes, various fiber fabrics, and the like. Rubbers, plastics and their products, glass, ceramic products, mica, asbestos and their products have a high resistivity and do not conduct electricity at the permitted voltages.
The heat insulation member 13 is used for heat insulation, and the heat insulation member 13 may be made of a porous material, a heat reflective material or a vacuum material. The porous material is insulated by the pores of the material (the thermal conductivity of air in the pores is low), and can be a foam material or a fiber material. Meanwhile, the pores of the porous material are convenient for smoke to pass through, and have an adsorption effect on a small amount of tar generated by heating in the smoke, so that the content of harmful substances in the smoke can be reduced. The heat reflecting material has high reflection coefficient, can reflect heat out, and can be gold, silver, nickel, aluminum foil or metal-plated polyester, polyimide film and other materials. The heat is difficult to transfer in vacuum, and the vacuum insulation material uses the internal vacuum of the material to achieve the purpose of blocking convection to insulate heat.
The first nano thermal insulation coating 14 is disposed on the thermal insulation member 13 and/or the insulation cylinder 12. Specifically, the first nano thermal barrier coating 14 may be provided on an inner wall surface and/or an outer wall surface of the thermal insulation member 13; alternatively, the first nano heat insulation coating 14 is provided on the inner wall surface and/or the outer wall surface of the insulation cylinder 12; alternatively, the first nano heat insulating coating 14 is provided on the inner wall surface and/or the outer wall surface of the heat insulating material 13 and the inner wall surface and/or the outer wall surface of the insulating tube 12. Of course, the first nano thermal barrier coating 14 may be provided on the inner wall surface of the outer shell 11, and the effect of suppressing heat transfer can be achieved as well.
The first nano thermal insulation coating 14 can be applied by spraying, dipping or brushing. Spraying: and spraying a nano material on the wall surface of the heat insulation piece 13 and/or the insulating cylinder 12 through a spray gun, wherein the nano material forms a dense nano coating on the wall surface of the heat insulation piece 13 and/or the insulating cylinder 12. The spraying construction method does not cause the erosion of raw materials, and has low operation difficulty and high production efficiency. Dip coating: and immersing the heat insulation piece 13 and/or the insulating cylinder 12 in a tank containing nano coating, after the nano coating forms a nano coating on the wall surface of the heat insulation piece 13 and/or the insulating cylinder 12, taking the heat insulation piece 13 and/or the insulating cylinder 12 out of the tank, and enabling the redundant nano coating to flow back into the tank along the wall surface of the heat insulation piece 13 and/or the insulating cylinder 12 again. The construction method of dip coating has an advantage in that the loss of coating is relatively small. Brushing: manually brushing nano paint on the wall surface of the heat insulation piece 13 and/or the insulating cylinder 12 through a brush, wherein the nano paint forms a nano coating on the wall surface of the heat insulation piece 13 and/or the insulating cylinder 12. The brush coating construction method does not need the investment of equipment and clamps, and has low cost and simple operation.
The electronic cigarette 1 of the utility model comprises a shell 11, an insulating cylinder 12, a heat insulating piece 13 and a first nanometer heat insulating coating 14; the insulating cylinder 12 is arranged in the shell 11, and a heat insulation cavity 121 is formed between the outer wall surface of the insulating cylinder 12 and the inner wall surface of the shell 11 at intervals; the heat insulation piece 13 is arranged in the heat insulation cavity 121; the first nanometer heat insulation coating 14 is arranged on the heat insulation piece 13 and/or the insulation cylinder 12; thus, the unique nano-pore structure of the first nano thermal insulation coating 14 limits the free flow of air molecules and inhibits the convective conduction of air, and the infinite pore walls of the first nano thermal insulation coating 14 form a reflecting surface and a refracting surface of heat radiation, so that the radiation heat conduction is inhibited to the maximum extent; therefore, the shell 11 of the electronic cigarette 1 is always lower than 45 ℃ in the using process of a user, and the using comfort of the user cannot be influenced by overhigh temperature.
Referring to fig. 1 to 4, the first nano thermal insulation coating 14 is disposed on an inner wall surface of the thermal insulation member 13. The inner wall surface of the heat insulator 13 is a wall surface of the heat insulator 13 close to the insulating cylinder 12. When the first nano thermal barrier coating 14 is provided on the inner wall surface of the thermal barrier 13, the first nano thermal barrier coating 14 can inhibit convective conduction and radiative conduction of air near the inner wall surface of the thermal barrier 13, thereby limiting the transfer of heat to the thermal barrier 13 and further to the housing 11. Of course, the first nano thermal insulation coating 14 may also be disposed on the inner wall surface of the insulating cylinder 12, that is, on the wall surface of the insulating cylinder 12 away from the outer shell 11, and the first nano thermal insulation coating 14 inhibits the convection conduction and the radiation conduction of air near the inner wall surface of the insulating cylinder 12, so as to inhibit the heat from being transferred to the insulating cylinder 12, further transferred to the thermal insulation member 13 through the thermal insulation cavity 121, and further transferred to the outer shell 11 through the thermal insulation member 13. The first nanometer thermal insulation coating 14 limits air convection conduction and radiation heat conduction, so that the outer wall surface of the shell 11 is always lower than 45 ℃ in the using process of a user, and the using comfort of the user cannot be influenced by overhigh temperature.
Referring to fig. 1 to 4, the electronic cigarette 1 further includes a second nano thermal insulation coating 15, and the second nano thermal insulation coating 15 is disposed on an outer wall surface of the thermal insulation member 13. The outer wall surface of the heat insulator 13 is a wall surface of the heat insulator 13 close to the housing 11. The second nano thermal barrier coating 15 can inhibit convective conduction and radiative conduction of air near the outer wall surface of the thermal barrier 13, thereby limiting the heat transfer of the thermal barrier 13 to the housing 11 via the thermal barrier chamber 121. Similarly, the second nano thermal barrier coating 15 may be provided on the outer wall surface of the insulating tube 12, that is, on the wall surface of the insulating tube 12 close to the outer shell 11. The second nano thermal barrier coating 15 can inhibit convective conduction and radiative conduction of air near the outer wall surface of the insulating cylinder 12, thereby limiting the heat transfer of the insulating cylinder 12 to the thermal insulation cavity 121. The second nano heat insulation coating 15 limits air convection conduction and radiation heat conduction, and can also reduce the temperature of the outer wall surface of the shell 11, thereby improving the comfort of users.
In one embodiment, the thickness of the first nano thermal barrier coating 14 is greater than or equal to 0.1 μm and less than or equal to 0.5 μm. When the thickness of the first nano thermal insulation coating 14 is less than 0.1 μm, the thickness of the first nano thermal insulation coating 14 is relatively thin, the effect of limiting the convection and conduction of air is not good, the number of the heat radiation reflecting surfaces and the refraction surfaces formed on the hole wall is not enough, and the effect of inhibiting the radiation and heat conduction is also not good. When the thickness of the first nano thermal barrier coating 14 is more than 0.5 μm, on the one hand, material is wasted, and on the other hand, the effect of suppressing the heat transfer is lowered. The thickness of the second nano thermal barrier coating 15 may also be greater than or equal to 0.1 μm and less than or equal to 0.5 μm, so that the second nano thermal barrier coating 15 also has a relatively good effect of inhibiting heat transfer.
Further, the thickness of the first nano thermal barrier coating 14 is greater than or equal to 0.3 μm and less than or equal to 0.4 μm. When the thickness of the first nano thermal barrier coating layer 14 is within the above range, the effect of suppressing heat transfer is better. The thickness of the second nano thermal barrier coating 15 may also be greater than or equal to 0.3 μm and less than or equal to 0.4 μm, so that the second nano thermal barrier coating 15 also has a better function of inhibiting heat transfer.
The material of the first nano thermal insulation coating 14 includes at least one of nano silver, nano chromium aluminum nitride, nano titanium silicon nitride, nano titanium aluminum nitride, nano silicon zirconium nitride, nano tin nitride, nano zirconium dioxide, nano titanium dioxide, nano silicon dioxide or nano antimony tin oxide. The first nano thermal insulation coating 14 can be coated by multiple layers of the same nano material, and can also be coated by overlapping different nano materials according to the characteristics of different nano materials. The first nano thermal insulation coating 14 and the second nano thermal insulation coating 15 may be made of the same nano material, or may be made of different nano materials, which is not limited herein.
Referring to fig. 1 to 4, the electronic cigarette 1 includes a heating element 16, the heating element 16 is disposed in the insulating cylinder 12, and the heating element 16 is spaced apart from the insulating cylinder 12. Specifically, a mounting cavity 161 is formed between the heating element 16 and the insulating cylinder 12 at an interval.

The heating member 16 may have a substantially cylindrical shape, a substantially square cylindrical shape, a substantially polygonal cylindrical shape, or a substantially elliptical cylindrical shape, so that the heating member 16 is adapted to the shape of the insulating cylinder 12, and thus has a good insulating effect.

The mouthpiece cartridge 171 and the mouthpiece cover 172 may be bonded, screwed or snap-fit. The mouthpiece 171 may be set to have a relatively long length, and the lengthened mouthpiece 171 prolongs the time for the smoke to reach the mouth, so as to reduce the temperature of the smoke reaching the mouth, thereby preventing the mouth from being scalded by the too high temperature of the smoke. The mouthpiece cover 172 may be made of a flexible material, such as a silicone material or a rubber material, so as to prevent the mouthpiece cover 172 from hurting the mouth. Meanwhile, the mouthpiece cover 172 is made of a flexible material, so that the mouth feel of a real mouthpiece can be simulated, and the use experience of a user is improved.
