[0018] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below in conjunction with the specific embodiments. Preferred embodiments of the present invention are provided in the specific embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0020] The material of the cigarette cartridge shell of one embodiment includes a polymer and a silver ion additive, wherein the mass of the silver ion additive is 0.1% to 0.3% of the mass of the polymer.
[0021] The polymer is selected from at least one of PCTG, ABS, PC, PEEK, PEI, PPSU, POM and PP. The above polymers are all materials that meet the food safety grade requirements and are used in the preparation of the cartridge shell so that no harmful substances are generated when the electronic cigarette oil is inhaled. It can be understood that the polymer used in this embodiment is not limited to the above types, and can also be a polymer material commonly used in the art.
[0022] The silver ion additive is silver-loaded zirconium phosphate. The particle size of the silver ion additive is 0.5 μm to 1.5 μm. Furthermore, the particle size of the silver ion additive is 1 μm. Furthermore, the silver ion additive is Novaron Ag300 produced by Toa Gosei Co., Ltd. By adding the silver ion additive, the cigarette cartridge can produce peroxide (such as O2 - , hydrogen peroxide molecules, etc.) to achieve a bactericidal effect. The use of silver-loaded zirconium phosphate as a silver ion additive has excellent bactericidal effect. When used in a small amount, it improves the bactericidal effect and has little effect on the taste of electronic cigarette oil. On the other hand, the above-mentioned silver ion additive has good safety in use and is used in the preparation of the cartridge shell, which is harmless to the human body.
[0023] The mass of the silver ion additive is 0.1%, 0.2% or 0.3% of the mass of the polymer. Experiments have shown that the silver ion additive has a good bactericidal effect when used in the above amount, and has little effect on the taste of the electronic cigarette oil.
[0024] Specifically, the shell includes an inner layer and an outer layer. In one embodiment, the materials of the inner layer and the outer layer of the shell are the same, both of which are a mixture of a polymer and a silver ion additive. In another embodiment, the materials of the inner layer and the outer layer of the shell are different, the material of the inner layer of the shell is a polymer, which is obtained by processing and molding the polymer, and the material of the outer layer of the shell is a mixture of a polymer and a silver ion additive, which is obtained by processing and molding the polymer and the silver ion additive. The inner layer uses a polymer without adding a silver ion additive, and the outer layer uses a polymer with adding a silver ion additive, so that the silver ion additive does not affect the taste of the smoke oil, but at the same time can have a bactericidal effect on the outer surface environment of the shell of the smoke cartridge.
[0025] The above-mentioned cigarette cartridge housing has at least the following advantages:
[0026] (1) The above-mentioned cartridge shell is added with silver ion additives, so that the cartridge can produce peroxide (such as O2 - , hydrogen peroxide molecules, etc.) to achieve a bactericidal effect. The silver ion additive has a good bactericidal effect, and can achieve a good bactericidal effect when used in a small amount, and has little effect on the taste of the smoke oil.
[0027] (2) When the above-mentioned cartridge shell is used in a cartridge, there is no need to provide an additional sterilization component to sterilize the shell, which makes the cartridge structure simpler, more convenient to use, and lower in cost.
[0028] A method for preparing a cigarette cartridge shell in one embodiment comprises the following steps: processing and molding a preparation raw material comprising a polymer and a silver ion additive to prepare a cigarette cartridge shell, wherein the mass of the silver ion additive is 0.1% to 0.3% of the mass of the polymer.

Then the mixture is transferred from the hopper to the barrel, and after the pre-molding and melting process, it is metered and compressed. Finally, the mixture is injected into the mold, and after the mold is cooled, the molded cartridge shell is ejected and demolded to obtain the final cartridge shell.
[0030] It can be understood that the specific injection molding method and process parameters may be commonly used methods and parameters in the art and will not be described in detail here.
[0031] In one embodiment, the step of processing the raw material containing the polymer and the silver ion additive into a shape comprises: mixing the polymer and the silver ion additive, and then injection molding.

[0033] The polymer is once injection molded to form an inner layer to obtain a semi-finished product;
[0034] The polymer and the silver ion additive are mixed and then subjected to secondary injection molding to form an outer layer on the semi-finished product to obtain a cartridge shell.
[0035] Specifically, the first injection molding obtains the inner layer of the cartridge shell, and the second injection molding obtains the outer layer of the cartridge shell. The inner layer uses a polymer without silver ion additives, while the outer layer uses a polymer with silver ion additives, so that the silver ion additives will not affect the taste of the e-liquid, but at the same time can have a bactericidal effect on the outer surface environment of the cartridge shell.
[0036] The polymer is selected from at least one of PCTG, ABS, PC, PEEK, PEI, PPSU, POM and PP. The above polymers are all materials that meet the food safety grade requirements and are used in the preparation of the cartridge shell so that no harmful substances are generated when the electronic cigarette oil is inhaled. It can be understood that the polymer used in this embodiment is not limited to the above types, and can also be a polymer material commonly used in the art.
[0037] The silver ion additive is silver-loaded zirconium phosphate. The particle size of the silver ion additive is 0.5 μm to 1.5 μm. Furthermore, the particle size of the silver ion additive is 1 μm. Furthermore, the silver ion additive is Novaron Ag300 produced by Toa Gosei Co., Ltd. By adding the silver ion additive, the cigarette cartridge can produce peroxide (such as O2 - , hydrogen peroxide molecules, etc.) to achieve a bactericidal effect. The above silver ion additive is used because of its excellent bactericidal effect. When used in a small amount, it improves the bactericidal effect and has little effect on the taste of the electronic cigarette oil. On the other hand, the above silver ion additive is safe to use and is used in the preparation of the cartridge shell, which is harmless to the human body.
[0038] The mass of the silver ion additive is 0.1%, 0.2% or 0.3% of the mass of the polymer. Experiments have shown that the silver ion additive has a good bactericidal effect when used in the above amount, and has little effect on the taste of the electronic cigarette oil.
[0039] The preparation method of the cigarette cartridge shell is simple in process, and the prepared cigarette cartridge shell has a good sterilization effect.
[0040] A cigarette cartridge of one embodiment includes a cigarette cartridge housing and an atomizer of the above embodiment. The cigarette cartridge housing is provided with a receiving cavity, and the atomizer is arranged in the receiving cavity. The cigarette cartridge housing can also store smoke oil. It is understood that the cigarette cartridge can also have other structures commonly used in the art, which will not be described here.
[0041] The cigarette cartridge has a good sterilization effect, a simple structure, good safety when in use, and little effect on the smoking taste.
[0042] An electronic cigarette of one embodiment includes a cartridge of the above embodiment and a cigarette rod connected to the cartridge. The cartridge can carry the cigarette oil and convert the cigarette oil therein into smoke for the user to inhale, and the cigarette rod is used to provide the cigarette cartridge with energy required to convert the cigarette oil into smoke, such as electrical energy. The cigarette cartridge and the cigarette rod can be detachably connected, for example, by threaded connection, magnetic connection, snap connection, etc. It can be understood that the electronic cigarette can also have other commonly used structures, which will not be repeated here.
