Description

Technical Field

[0001] The present invention relates to the field of electronic cigarettes, and in particular to a protective film for smoke condensation, a manufacturing method, a cigarette cartridge and an electronic cigarette. Background Art

[0002] The essence of electronic cigarettes is that the airflow sensor acts as a switch when inhaling, converting the airflow movement into an electrical signal. After the circuit is connected, the battery powers the atomization unit, and the smoke liquid is atomized through the conversion of electrical energy into thermal energy.

[0003] In daily practice, it is found that the existing technical solutions have the following problems:

[0004] At present, electronic cigarettes on the market generally have oil leakage problems caused by condensation. The specific phenomenon is that when people smoke electronic cigarettes, condensed smoke oil will be generated in the smoke channel. Due to gravity, the condensed smoke oil will flow back into the inside of the cigarette rod along the smoke channel, causing corrosion damage to the airflow sensor and PCB circuit components. In addition, users may blow the electronic cigarette backwards during the actual smoking process, causing more smoke to enter the cigarette rod through the channel, thereby generating more condensation inside it.

[0042] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0043] Example 1

[0044] like Figure 1 and Figure 2 As shown, a protective film for electronic cigarette smoke condensation includes: a metal support mesh 1 and a fiber membrane 2, the fiber membrane 2 is attached to the metal support mesh 1, and the surface of the fiber membrane 2 is coated with oleophobic nanomaterials.

[0045] The metal support mesh 1 can be made of metal materials with good heat dissipation, such as copper material, aluminum material, silver material, and iron material.

[0046] The metal support mesh 1 is preferably made of copper material with good heat dissipation performance and relatively low cost.

[0047] It should be noted that, under the premise that the protective film can effectively condense the smoke in the electronic cigarette, the metal support mesh 1 can also be made of other metal materials with good heat dissipation, such as aluminum alloy materials, magnesium alloy materials, etc.

[0048] The fiber membrane 2 is made of a mixture of one or more of polyacrylonitrile, polymethyl methacrylate, polystyrene, polyurethane, cellulose acetate, and polyimide, and is produced by an electrostatic spinning process.

[0049] The oleophobic nanomaterial coated on the surface of the fiber membrane 2 can be nano-silicon dioxide, fluorosilicone resin nano-coating, modified resin nano-coating material, fluorinated polymer nano-coating and other materials with oleophobic function. In addition, oleophobic materials that can repel the oil formed by electronic cigarette smoke can also be coated on the surface of the fiber membrane 2.

[0050] The super-phobic treatment reagent coated on the surface of the fiber membrane 2 is preferably an ethanol reagent solution of nano-silicon dioxide.

[0051] Preferably, the metal support mesh 1 is 80-500 meshes.

[0052] Preferably, the fiber membrane 2 is combined with the metal support mesh 1 by an electrostatic spinning process. The fibers formed during the electrostatic spinning process will penetrate into the mesh of the metal support mesh 1 and form the fiber membrane 2 on the surface of the metal support mesh 1.

[0053] Preferably, the protective film has an air permeability of 10000-80000 ml / min / cm2 under 1 KPa, an air resistance of 50-800 Pa, and an interception efficiency of not less than 90% for particles of 0.02-2 μm.

[0054] Example 2

[0055] Based on the same inventive concept, this embodiment provides a method for manufacturing a protective film for electronic cigarette smoke condensation, which is used to manufacture the protective film for smoke condensation in Example 1, comprising the following steps:

[0056] S1. According to the design requirements, select a metal support mesh of preset size and specification, and perform ultrasonic cleaning on the metal support mesh for 30-120 minutes.

[0057] Specifically, a metal support mesh with a mesh size of 80-500 is selected as a raw material for ultrasonic cleaning to remove stains and rust on the surface, thereby providing the necessary support foundation and attachment conditions for subsequent processes.

[0058] S2. Install the cleaned metal support mesh on a spinning device for spinning to form a fiber membrane on the metal support mesh.

[0059] S3. Use a super-repellent treatment agent and perform super-repellent treatment on the fiber membrane by immersion or spraying.

[0060] Preferably, the cleaned metal support mesh is mounted on a spinning device for spinning, and when a fiber membrane is formed on the metal support mesh, spinning is performed using an electrostatic spinning process using a spinning solution.

[0061] Specifically, the spinning solution is a mixture of one or more of polyacrylonitrile, polymethyl methacrylate, polystyrene, polyurethane, cellulose acetate, and polyimide. In other words, any one of polyacrylonitrile, polymethyl methacrylate, polystyrene, polyurethane, cellulose acetate, and polyimide can be selected as the spinning solution, or two or more of the materials of polyacrylonitrile, polymethyl methacrylate, polystyrene, polyurethane, cellulose acetate, and polyimide can be mixed and used as the spinning solution.

[0062] Furthermore, the solid content of the spinning solution is 5-40%, and the viscosity at 25° C. is 5000-25000 CPS.

[0063] Among them, when the spinning liquid is used for electrospinning, the temperature range is 22-28°C, the humidity range is 30%-55%, the positive high voltage range is 10-50Kv, the negative high voltage range is -30-0Kv, the receiving distance range is 10-35cm, and the liquid pushing speed is 1-50ml / H.

[0064] Furthermore, when the fiber membrane is treated with a superphobic treatment agent by immersion or spraying, the superphobic treatment agent includes an ethanol reagent solution of nano-silicon dioxide, the solid content of the ethanol reagent solution of nano-silicon dioxide is in the range of 0.5%-6%, and the nanoparticle size is in the range of 5-16nm.

[0065] Furthermore, when the fiber membrane is subjected to superphobic treatment by using a superphobic treatment agent and immersion or spraying treatment, it is dried at a temperature of 80° C. to 120° C. for 20 to 60 minutes for curing.

[0066] In this embodiment, the protective film for smoke condensation prepared by this method was tested. During the test, the atomization device of the electronic cigarette was simulated to simulate the normal suction, and the changes in the surface state and air permeability of the protective film before and after the test were compared. Among them, the atomization solvent used was national standard smoke oil, the atomization time was 1h, and the solvent consumption was 12ml.

[0067] Table 1 Test results of smoke condensation protective film

[0068]

[0069]

[0070] The test results show that when the protective film for smoke condensation prepared by this method is placed at an angle, under the condition of simulating normal electronic cigarette inhalation, the condensate can slide off smoothly, effectively avoiding the adhesion of foreign matter. At the same time, according to the air permeability data, the protective film for smoke condensation prepared by this method under the condition of simulating normal electronic cigarette inhalation has a minimum air permeability difference of even 30ml / min / cm 2 , before and after the test, there was only a 0.09% reduction rate, which was a good effect.

[0071] Example 3

[0072] Based on the same inventive concept, Figure 3-Figure 7 As shown, this embodiment provides a cigarette cartridge, including the protective film 40 for smoke condensation in Example 1. The protective film 40 is used to condense the smoke, which can prevent the smoke condensate in the cigarette cartridge from flowing back, thereby preventing the smoke condensate from corroding or damaging the internal components of the electronic cigarette.

[0073] Furthermore, the cigarette cartridge also includes a mouthpiece 10, an oil storage tank 20, an atomizer 30, a cigarette cartridge base 50, and an air channel 52 for drawing air into the atomizer 30; the air channel 52 passes through the cigarette cartridge base 50 and is connected to the atomizer 30; the protective film 40 covers the air channel 52; the protective film 40 is inclined relative to the cross-section of the cigarette cartridge.

[0074] Specifically, the oil storage tank 20 includes an oil storage tank shell 21 and an oil storage cavity 22 disposed in the oil storage tank shell 21, and the oil storage cavity 22 is used to store the tobacco oil. The atomizer 30 is disposed below the oil storage tank 20, and has a plurality of interconnected holes inside. The atomizer 30 contacts the tobacco oil in the oil storage cavity 22, and the tobacco oil can enter the inside of the atomizer 30 under the capillary action. At the same time, the atomizer 30 has a heating device inside, which can heat the tobacco oil in the holes inside the atomizer 30 when the electronic cigarette is smoked, so that the tobacco oil changes into smoke.

[0075] In addition, the cigarette cartridge also includes a sealing bracket 70 for fixing the atomizer 30. The sealing bracket 70 is fixed inside the oil storage tank housing 21, and the atomizer 30 is fixedly connected to the lower part of the sealing bracket 70. An oil tank seal 80 is provided between the sealing bracket 70 and the oil storage tank 20 to prevent the oil leakage between the sealing bracket 70 and the oil storage cavity 22.

[0076] Furthermore, the cigarette cartridge also includes an atomizer sealing gasket 90 disposed between the sealing bracket 70 and the atomizer 30 to prevent the cigarette oil from leaking between the sealing bracket 70 and the atomizer 30 .

[0077] It should be noted that the lower part of the oil storage chamber 22 has a smoke oil circulation channel. Although the smoke cartridge is provided with a sealing bracket 70, an oil tank seal 80 and an atomizer sealing gasket 90, they do not block the smoke oil passing area between the smoke oil circulation channel and the atomizer 30, thereby ensuring that the atomizer 30 maintains contact with the smoke oil in the oil storage tank 20, and is used to ensure that the smoke oil in the oil storage chamber 22 smoothly enters the holes inside the atomizer 30, and enters to ensure effective atomization of the smoke oil.

[0078] Furthermore, the cigarette cartridge base 50 includes an inclined portion 53 through which the air channel 52 passes; the upper surface of the inclined portion 53 is an inclined plane 54; the protective film 40 is fixedly connected to the inclined plane 54 and covers all the air channel 52 outlets on the inclined plane 54.

[0079] Preferably, the protective film 40 is fixedly connected to the inclined plane 54 by means of heat melting, welding, gluing or by using a fixed connecting piece.

[0080] As another embodiment of the present invention, the smoke cartridge further includes an oil collection chamber 51 for collecting liquid smoke condensate rolling down the surface of the protective film 40; an oil adsorbent 60 for adsorbing oil by capillary action is arranged in the oil collection chamber 51.

[0081] It should be noted that both natural fiber adsorption materials and non-polar adsorption materials that can utilize capillary phenomena to absorb oil can be used to make the oil adsorption member 60. In addition, the oil adsorption member 60 can be made of two or more materials of natural fiber adsorption materials and non-polar adsorption materials. For example: natural fiber materials can be selected from cotton, coconut shell fibers, etc., synthetic materials can be selected from polypropylene fibers, polyurethane foams, etc., and inorganic materials can be selected from activated carbon, diatomaceous earth, etc. In addition, when the oil adsorption member 60 is a granular material, the material can be fixed by high-temperature heating, sintering, bonding, mechanical compression, etc., to ensure that the oil adsorption member 60 can be fixed in the oil collection chamber, thereby preventing the particles in the oil adsorption member 60 from falling off.

[0082] Example 4

[0083] Based on the same inventive concept, Figure 8 As shown, combined with Figure 3-Figure 7 This embodiment provides an electronic cigarette, comprising a cigarette cartridge 100 and a cigarette rod 200 in claim embodiment 3. The cigarette cartridge 100 and the cigarette rod 200 are detachably fixedly connected.

[0084] In this embodiment, an electronic cigarette including a protective film 40 for smoke condensation and an electronic cigarette without a protective film installed were tested. Among them, the test samples selected 5 pieces of electronic cigarettes with and without fiber membrane components installed, for a total of 10 pieces of samples. During the test, the electronic cigarette was actually inhaled, and the oil in the cartridge was replaced with a new cartridge after the oil in the cartridge was exhausted. After inhaling 1 cartridge and 5 cartridges respectively, observe and compare whether there are oil stains caused by condensation at the junction of the cartridge and the cigarette rod and in the airway of the cigarette rod. The test results are shown in Table 2.

[0085] Table 2 Comparison of electronic cigarette test results

[0086]

[0087] Judging from the test results, there is no oil stain in the air passage at the front end of the electronic cigarette atomizer equipped with a protective film for smoke condensation, and the protective effect of the smoke condensation liquid is significant.
