[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1 As shown, a rotating structure of an electronic cigarette according to an embodiment of the present invention includes an atomizing component and a rotating component.

[0034] The atomizing component includes a mouthpiece 1. Below the mouthpiece 1, there is an oil cup 4. At least two oil storage chambers are provided in the oil cup 4, or more than two. In this embodiment, three oil storage chambers are taken as an example. A mouthpiece silicone cover 3 is sleeved between the oil cup 4 and the mouthpiece 1, and mouthpiece cotton 2 is provided in the mouthpiece silicone cover 3; an oil cup end cap 9 is sleeved at the bottom of the oil cup 4, and an upper electrode 8 is installed on the oil cup end cap 9. An oil cup silicone 5 is sleeved between the oil cup 4 and the oil cup end cap 9, and first oil-absorbing cotton 6 is provided in the oil cup silicone 5; further includes a ceramic atomizing core assembly 7, which is composed of a ceramic atomizing core and a silicone sleeve. The ceramic atomizing core is connected to the upper electrode 8; further includes an upper shell 10 sleeved outside the oil cup 4. The top of the upper shell 10 is connected to the mouthpiece 1, and the bottom is connected to the rotating component.

[0035] The rotating assembly includes a rotating base 11 and an upper fixing base 13. The top of the rotating base 11 is connected to the bottom of the upper shell 10. The upper fixing base 13 is sleeved inside the rotating base 11 and can be rotated driven by the rotating base 11. An elastic electrode 16 is installed on the upper fixing base 13, and the elastic electrode 6 can be electrically connected to the upper electrode 8.

[0036] As Figures 1-3 shown, in one embodiment, the oil cup is a cylinder, and a plurality of first partition walls 41 are provided inside the oil cup. The first partition walls form a plurality of independent oil storage chambers. A second partition wall 42 is provided between adjacent first partition walls. The first partition walls and the second partition wall 42 divide the oil cup into a plurality of independent oil storage chambers 43 and air passage chambers 44. The air passage chamber 44 is located directly below the mouthpiece 1 and communicates with the mouthpiece 1. A atomizing core accommodating cavity 45 and electrode mounting posts (including a first electrode mounting post 46 and a second electrode mounting post 47) are provided in each oil storage chamber 43. A transparent area is provided on the outer wall of each oil storage chamber, and a hollowed-out area corresponding to the transparent area is provided on the upper shell 10.

[0037] Due to the above structure, compared with traditional products, the present utility model only needs one oil cup and does not require multiple cartridges to achieve the function of an electronic cigarette with multiple flavors. Moreover, the separate air passage at the air outlet end reduces the possibility of flavor mixing. The setting of the atomizing core accommodating cavity 45 facilitates the installation of a flat ceramic atomizing core with high atomizing efficiency. The split-type oil storage design can make full use of the space, especially the space where the air passage chamber is located, so that the present utility model does not need to separately set an air passage in the oil storage chamber, improving the space utilization rate of the product and making the e-cigarette oil capacity of the product with the same volume large. The air outlet air passage chamber is located directly below the mouthpiece, with smooth smoke outlet and a small probability of condensate formation, effectively improving the use experience. By providing a visual transparent area on the outer wall of the oil storage chamber, the use condition of the e-cigarette oil can be directly observed, facilitating the user to observe the state of the e-cigarette oil.

[0038] As Figures 4-8As shown, in one embodiment, the rotating base 11 is composed of an upper connecting portion 111, a middle portion 112, and a lower connecting portion 113. The upper connecting portion 111 is fixedly connected to the upper shell 10 and the oil cup 4 by means of adhesive bonding, snap connection, threading, or screwing; the middle portion 112 protrudes outward relative to the upper connecting portion 111 and the lower connecting portion 113 to support the upper shell 10 and the lower shell 18; the lower connecting portion 113 has a circular outer wall that is concave inward relative to the outer wall of the middle portion 112, and the inner wall of the bottom of the lower connecting portion 113 has a concave step portion 114 that protrudes inward. The upper fixing base 13 is composed of a base body 131 and a convex step portion 132. The convex step portion 132 is provided on the base body 131. A plurality of screw holes 133, two electrode holes 134, an air inlet 135, and a cotton wick mounting port 136 are provided on the surface of the base body 131. The upper fixing base 13 is installed inside the rotating base 11 and rotates and slides by the mutual support of the concave step portion 114 and the convex step portion 132; the base body 131 is fixedly connected to the bracket 17 by three screw holes and screws; the air inlet passage of the e-cigarette power supply component can be introduced into the internal space of the oil cup 4 through the air inlet 135; elastic electrodes 16 are arranged through the electrode holes 134 to be connected to the electrodes of the atomization component. The rotating base is preferably a metal part with a certain strength, and the upper fixing base is preferably made of POM material, which has high reliability and firm rotation. In particular, the rotating base is made of aluminum alloy material, which is convenient for processing and has a certain strength.

[0039] Due to the above structure, in the present utility model, a concave step portion 114 is provided at the bottom of the rotating base 11, and a convex step portion 132 is provided at the top of the upper fixing base 13. Through the cooperation of the concave step portion and the convex step portion, rotational docking is achieved; compared with the traditional rotational connection method using an intermediate support column and intermediate screw fixation, the space utilization rate of the atomization component is greatly improved, and the firmness and reliability are high.

[0040] Preferably, an uneven pattern is provided on the middle portion 112 of the rotating base to improve the feel of rotation and the overall aesthetics.

[0041] Preferably, more than three screws or bolts are provided for fixation, which are evenly distributed on the upper fixing base 13, and the fixation is firm and there is no risk of being pried open.

[0042] As Figures 1-3As shown, in one embodiment, there are two elastic electrodes 16, namely a first elastic electrode 161 and a second elastic electrode 162. Each ceramic atomizing core is correspondingly connected to two upper electrodes, namely a first upper electrode 81 and a second upper electrode 82. A concave positioning hole 83 is provided at the bottom of the first upper electrode 81. The first upper electrode 81 is installed in a first electrode mounting post 46, and the second upper electrode 82 is installed in a second electrode mounting post 47. When the first elastic electrode rotates, it can fall into the positioning hole 83 of the first upper electrode connected to one of the atomizing cores. Thus, through the cooperation of the elastic electrode 16 and the upper electrode 8, rotational positioning is achieved. Using a spring electrode for positioning, compared with traditional products, there is no need to use positioning marbles, the installation is convenient, and the structure is simple.

[0043] As Figure 1 shown, in another embodiment, the present invention further includes a lower shell 18 and a bracket 17. The lower shell 18 is sleeved on the bottom of the rotating seat 11, and the bracket 17 is connected to the bottom of the upper fixing seat 13.

A first rubber ring 12 is provided at the place where the rotating seat 11 and the lower shell 18 are sleeved, and a second rubber ring 14 is provided at the place where the air inlet 135 of the upper fixing seat 13 contacts the air passage hole 171 of the bracket to seal the air passage. The first rubber ring 12 and the second rubber ring 14 can be arranged at corresponding positions on the rotating seat 11 and the upper fixing seat 13 by providing corresponding mounting grooves, or can be arranged on the lower shell 18 and the bracket 17.

[0044] Working principle of the present invention: For the rotary electronic cigarette of the present invention, when in use, the user rotates the middle part 112 of the rotating seat 11 left and right, and the rotating seat 11 drives the upper fixing seat 13 to rotate. When the elastic electrode 16 on the upper fixing seat 13 slides into the positioning hole 83 of the upper electrode 8, the upper electrode 8 is connected to the ceramic atomizing core. When the elastic electrode 16 is connected to the power supply component power source of the electronic cigarette, the ceramic atomizing core can be powered on to start working. An aerosol is generated in the oil storage chamber where the ceramic atomizing core is located. The aerosol enters the corresponding airway chamber from the bottom of the atomizing core and enters the mouthpiece approximately vertically, and can then be inhaled by a person.
