By manually pushing the hand-pushing part 500, the cigarette holder 400 slides along the direction of the first through hole 311, so that the cigarette holder 400 enters the accommodating cavity 110 and extends out of the accommodating cavity 110.

[0025] In a specific embodiment, the outer shell 100 is roughly in the shape of a rectangular parallelepiped. The outer shell 100 is the external protective structure of the electronic cigarette with a retractable mouthpiece, which plays the role of protecting internal components and providing overall shape support. The outer shell 100 and the cover plate 200 together constitute the outer shell of the electronic cigarette, providing a space frame for the installation of other components.

[0026] The cover plate 200 is roughly rectangular, and the shape of the cover plate 200 matches the shape of the outer shell 100. The cover plate 200 cooperates with the outer shell 100, and the two are assembled together by a suitable connection method (such as buckles, screws, etc., which can be selected according to actual design) to form a relatively closed accommodating cavity 110. This accommodating cavity 110 is the placement space for the internal components of the entire retractable mouthpiece electronic cigarette, ensuring that each component can work in a relatively stable environment.

[0027] The oil storage bin 600 is mainly used to store the oil required for the electronic cigarette with a retractable mouthpiece during use. The oil storage bin 600 is located inside the accommodating cavity 110. On the one hand, the mounting block 300 is fixedly assembled with the oil storage bin 600 to ensure a firm connection between the two. On the other hand, a fixing column 310 is provided on the side away from the oil storage bin 600. A first through hole 311 is provided in the middle of the fixing column 310. The first through hole 311 passes through the mounting block 300 and is communicated with the oil storage bin 600.

[0028] The cigarette holder 400 is a direct component for the user to inhale smoke, and the cigarette holder 400 includes a connecting column 410, which matches the first through hole 311 and is slidably assembled in the first through hole 311. The cigarette holder 400 also includes an inhalation channel, which runs through the connecting column 410 and is used for the user to inhale smoke formed by atomization of the smoke oil.

[0029] The hand-pushing part 500 is fixedly connected to the cigarette holder 400, and the hand-pushing part 500 is a part that the user manually operates to control the extension and retraction of the cigarette holder 400. The user pushes the hand-pushing part 500 by hand, and by virtue of the fixed connection between the hand-pushing part 500 and the cigarette holder 400, the connecting column 410 can slide in the first through hole 311 of the mounting block 300 in a desired direction, thereby realizing the extension and retraction function of the cigarette holder 400.

[0030] The boss 420 is a raised structure arranged on the side of the cigarette holder 400 close to the push portion 500. There are two bosses 420, which are arranged at intervals. In another specific embodiment, the number, shape and size of the bosses 420 can be adjusted according to actual design requirements.

[0031] The first mounting groove 421 is located on the boss 420, and the direction of the first mounting groove 421 is perpendicular to the axial direction of the connecting column 410. The mounting column 510 is a component of the hand-pushing part 500. The number of the mounting columns 510 corresponds to the number of the first mounting grooves 421 on the boss 420, and the shape of the mounting columns 510 matches the shape of the first mounting grooves 421 to ensure that the mounting columns 510 can be smoothly embedded in the first mounting grooves 421, thereby achieving a firm connection between the cigarette holder 400 and the hand-pushing part 500.

[0032] By arranging a convex column 420 and a first mounting groove 421 on one side of the cigarette holder 400 close to the push portion 500, and arranging a corresponding mounting column 510 on the push portion 500, an embedded connection method is adopted to make the connection between the cigarette holder 400 and the push portion 500 more firm and reliable. Secondly, the embedded connection is relatively simple and easy, and does not require complicated tools or processes during the assembly process, which reduces the production cost and assembly difficulty, and is conducive to improving production efficiency.

[0033] The assembly block 700 is a component located inside the accommodating cavity 110, and its main function is to assist the installation and sliding of the cigarette holder 400. A third installation groove is provided on the side of the assembly block 700 close to the mounting block 300. The shape of the third installation groove matches the shape of the mounting block 300. The mounting block 300 is embedded in the third installation groove, so that the mounting block 300 and the assembly block 700 are fixedly assembled. A first assembly groove 710 is provided on the assembly block 700. The shape and size of the first assembly groove 710 match the cigarette holder 400. The cigarette holder 400 is slidably arranged in the first assembly groove 710 to prevent the cigarette holder 400 from deflecting during movement. Two guide grooves 730 are also provided on the assembly block 700. The two guide grooves 730 are arranged in parallel and spaced apart. The guide grooves 730 are in the same direction as the first guide groove 210. The position of the guide groove 730 corresponds to the position of the boss 420. The boss 420 runs through the guide groove 730. The guide groove 730 not only makes way for the boss 420 but also guides the boss 420, thereby further preventing the cigarette holder 400 from deviating during movement.

[0034] The assembly block 700 provides additional support for the cigarette holder 400, making the cigarette holder 400 more stable during the extension process, reducing possible shaking or instability. The setting of the first assembly groove 710 makes the sliding of the cigarette holder 400 more standardized and smooth. The matching design of the first assembly groove 710 and the cigarette holder 400 ensures that the cigarette holder 400 will not get stuck or deviate from the predetermined track during the extension process, thereby improving the reliability of the extension action of the cigarette holder 400.

[0035] In summary, when the electronic cigarette is not in use, the mouthpiece 400 can be retracted into the accommodating chamber 110, which can effectively protect the mouthpiece 400 from damage by external collision, friction, etc., extend the service life of the mouthpiece 400, and effectively prevent dust or other debris in the air from contaminating the mouthpiece 400. When the user needs to use the electronic cigarette, the mouthpiece 400 can be quickly extended from the accommodating chamber 110 by simply pushing the hand-pushing part 500, which is very convenient and can meet the user's smoking needs in a timely manner.

[0036] like Figure 2 As shown, a plurality of first guide grooves 210 are provided on the cover plate 200 . The first guide grooves 210 match the mounting posts 510 , and the mounting posts 510 pass through the first guide grooves 210 .

[0037] In a specific embodiment, two first guide grooves 210 are provided on the cover plate 200. The first guide grooves 210 are linear and are arranged in parallel and spaced apart. The direction of the first guide grooves 210 is the same as the direction of the connecting column 410. The mounting column 510 runs through the first guide grooves 210. The main function of the first guide grooves 210 is to provide guiding and limiting functions for the mounting column 510 of the hand push part 500, which can ensure that the mounting column 510 moves in a predetermined direction during the movement to avoid offset and the like.

[0038] In summary, the first guide groove 210 provides a clear moving direction for the mounting column 510, so that the hand-pushing part 500 can move along a predetermined route, effectively preventing the hand-pushing part 500 from being offset, and ensuring the smoothness of the extension and retraction movement of the cigarette holder 400.

[0040] In a specific embodiment, the oil storage shell 610 is the external protective structure of the oil storage bin 600. The material of the oil storage shell 610 is generally selected to have a certain strength and corrosion resistance, such as plastic, metal alloy, etc., to ensure that it can remain intact for a long time during use to prevent the leakage of smoke oil. The oil storage shell 610 is roughly rectangular, and the two ends of the oil storage shell 610 have two openings. The interior of the oil storage shell 610 is an oil storage space, which is an area for storing smoke oil. The shape of the oil storage cotton 620 matches the shape of the oil storage space. The oil storage cotton 620 is placed in the oil storage space. The main function of the oil storage cotton 620 is to absorb and store smoke oil. The oil storage cotton 620 has good adsorption performance and can evenly disperse the smoke oil inside. An assembly hole 621 is provided in the oil storage cotton 620. The assembly hole 621 runs through the oil storage cotton 620. An atomization tube is provided in the assembly hole 621. The atomization tube is used to heat and atomize the smoke oil. The atomization tube is in close contact with the oil storage cotton 620, so that the oil storage cotton 620 stably supplies the smoke oil to the atomization tube. The atomization tube includes a gas channel, which runs through the atomization tube. The smoke formed after the smoke oil is atomized enters the gas channel.

[0041] like Figure 3 As shown, the oil storage bin 600 further includes a first blocking block 630 . A first opening 611 is provided on one side of the oil storage housing 610 close to the cigarette holder 400 .
