Electronic cigarette, electronic cigarette atomizer, and electronic cigarette-holder

1. An electronic cigarette comprising a cigarette-holder, wherein, the cigarette-holder includes a variable color material; and when the electronic cigarette is smoked, the variable color material generates a chemical reaction or a physical change and causes a color of the variable color material to change; wherein the variable color material is an inclusion generated by starch and iodine, and when the electronic cigarette is smoked, the starch in the inclusion is decomposed by salivary amylase in saliva and causes the color of the variable color material to change,

wherein the variable color material is arranged inside the cigarette-holder, the portion of the cigarette-holder that corresponds to the variable color material is configured to be transparent so that the user can watch the color change of the variable color material inside the cigarette-holder from a side of the electronic cigarette, the variable color material forms a variable color layer, and the variable color layer forms patterns and/or words,

wherein a thickness of the variable color layer ranges from 1 micron to 100 microns; wherein the variable color layer is formed by immersion, deposition, spraying or pasting; wherein the cigarette-holder further includes a liquid guiding member configured to lead saliva to the variable color material the liquid guiding member is a hollow cylinder with two open ends, one end of the liquid guiding member extends to a distal end of the electronic cigarette, and the other end of the liquid guiding member is in contact with the variable color material;

wherein the liquid guiding member is made of at least one material selected from sponge, cotton, acetate fiber, and nonwoven fabric; and wherein the cigarette-holder is designed as being integrated with a structure of the electronic cigarette.

2. The electronic cigarette according to claim 1 , wherein, the variable color material is an inclusion generated by amylose and iodine, and the variable color material is blue; and when the electronic cigarette is smoked, the amylose of the variable color material is decomposed by the salivary amylase, and the blue variable color material becomes transparent.

3. The electronic cigarette according to claim 1 , wherein, the variable color material is an inclusion generated by amylopectin and iodine, and the variable color material is purple; and when the electronic cigarette is smoked, the amylopectin of the variable color material is decomposed by the salivary amylase, and the purple variable color material becomes transparent.

4. The electronic cigarette according to claim 1 , wherein, the variable color material is a colorful sugar, and the colorful sugar melts when the electronic cigarette is smoked.

5. The electronic cigarette according to claim 4 , wherein, the sugar is made up of at least one selected from maltose, stevioside, sucrose, and glucose.

6. The electronic cigarette according to claim 1 , wherein, the variable color material is litmus, and when the electronic cigarette is smoked, carbon dioxide exhaled by a user causes the color of the litmus to change.

7. The electronic cigarette according to claim 1 , wherein, the variable color material is a silica gel desiccant, and when the electronic cigarette is smoked, the variable color material absorbs saliva and causes the color of the variable color material to change.

8. The electronic cigarette according to claim 7 , wherein, the variable color material is blue silica gel desiccant, and the variable color material becomes red when the electronic cigarette is smoked.

9. The electronic cigarette according to claim 7 , wherein, the variable color material is orange non-cobalt silica gel desiccant, and the variable color material becomes green when the electronic cigarette is smoked.

10. An electronic cigarette-holder, wherein, the cigarette-holder includes a variable color material, and when the electronic cigarette is smoked, the variable color material generated a chemical reaction, and causes the color of the variable color material to change;

wherein the variable color material is an inclusion generated by starch and iodine, and when the electronic cigarette is smoked, the starch in the inclusion is decomposed by salivary amylase in saliva and causes the color of the variable color material to change;

wherein the variable color material is arranged inside the cigarette-holder, the portion of the cigarette-holder that corresponds to the variable color material is configured to be transparent, so that the user can watch the color change of the variable color material inside the cigarette-holder from a side of the electronic cigarette, the variable color material forms a variable color layer, and the variable color layer forms patterns and/or words;

wherein a thickness of the variable color layer ranges from 1 micron to 100 microns;

wherein the variable color layer is formed by immersion, deposition, spraying or pasting;

wherein, the cigarette-holder further includes a liquid guiding member configured to lead saliva to the variable color material, the liquid guiding member is a hollow cylinder with two open ends, one end of the liquid guiding member extends to a distal end of the electronic cigarette, and the other end of the liquid guiding member is in contact with the variable color material;

wherein the liquid guiding member is made of at least one material selected from sponge, cotton, acetate fiber, and nonwoven fabric; and

wherein the cigarette-holder is designed as being integrated with a structure of the electronic cigarette.
