Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and specifically relates to a dual-flavor electronic cigarette. Background Art

[0002] An electronic cigarette is a product that atomizes nicotine and the like into steam for users to inhale through means such as atomization. Electronic cigarettes are mainly divided into atomized electronic cigarettes and heated tobacco products that do not burn. Among them, atomized electronic cigarettes can be further divided into disposable, cartridge-refillable, and refillable types according to the usage method.

[0003] E-liquid is a key component of electronic cigarettes and usually contains ingredients such as PG (propylene glycol), VG (vegetable glycerin also called glycerol), flavorings, nicotine salts, additives, etc. Different e-liquids can bring different taste experiences. The common color of e-liquid is golden yellow or colorless liquid, and it smells like tobacco. When added to an electronic cigarette and heated, it will be atomized, and the feeling of inhaling it is the same as smoking.

[0004] Currently, when using electronic cigarettes on the market, since only single-flavor inhalation can be performed, and when switching flavors, it is necessary to wait until the e-liquid is used up before switching. As a result, the existing electronic cigarettes cannot quickly switch flavors and have the function of internal battery-assisted heat dissipation. Therefore, a device is needed to improve the above problems. Summary of the Invention

[0011] When the protective cover rotates, it can drive the displacement sleeve plate to move up and down through the third rack.

[0012] Specifically, the side-end device includes a protective side plate, a second magnetic attraction piece, and an L-shaped air cylinder. The protective side plates are fixedly installed at both ends of the second magnetic attraction piece. The L-shaped air cylinder is fixedly installed on the inner side of the protective side plate close to the second magnetic attraction piece. A second piston rod is slidably inserted into the bottom end inside the L-shaped air cylinder. A first piston rod is slidably inserted into the top end inside the L-shaped air cylinder.

[0020] Beneficial effects of the present invention:

[0021] First, the present invention adopts a separate design through the shell and the bottom cover, and the shell can be rotated separately, so that after the shell is rotated by degrees, the shell can rotate the first cigarette bomb body or the second cigarette bomb body inside to align and contact with the PCB connecting plate inside the bottom cover, so that different flavors of cigarette oil can be atomized, and the first electrode spring needle, the second electrode spring needle and the third electrode spring needle are aligned with the first electrode and the second electrode, so that the remaining oil amount inside the first cigarette bomb body or the second cigarette bomb body can be sensed, and the task of quickly switching flavors can be completed.

[0022] Secondly, the present invention can prevent the outer shell and the bottom cover from rotating again by inserting the limiting iron plate into the interior of the sleeve plate. At the same time, the provision of the protective cover can prevent outsiders from accidentally touching the synchronous displacement plate. Moreover, when the limiting iron plate is moved out from the interior of the sleeve plate, it can drive the second rack to move from the first gear, so that the first rack can drive the insertion plate to be inserted into the bottom end of the bottom cover, and the dust accumulated in the bottom end of the bottom cover can be pushed out, thereby completing the cleaning of the bottom end of the bottom cover and assisting the heat dissipation of the battery inside the bottom cover.

Detailed implementation mode

[0036] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] Embodiment 1

[0039] As Figure 1 、 Figure 2 and Figure 3 shown, a dual-flavor electronic cigarette of the present invention includes an outer shell 2, a cigarette holder body 1 is installed on the top end of the outer shell 2, a second cartridge body 11 and a first cartridge body 3 are installed inside the outer shell 2, a cartridge body bracket 10 is installed at the bottom end of the outer shell 2, a return spring 9 is rotatably installed at the center of the bottom end of the cartridge body bracket 10, a spring cover 8 is fixedly installed at the bottom end of the return spring 9, a bottom cover 6 is fixedly installed at the bottom end of the spring cover 8, a battery 7 is installed inside the bottom cover 6, a PCB connecting plate bracket 4 is arranged inside the bottom cover 6, and the PCB connecting plate bracket 4 is located above the battery 7, a PCB connecting plate 5 is installed inside the PCB connecting plate bracket 4, three second electrodes 13 and a first electrode 12 are arranged inside the cartridge body bracket 10, and a first electrode spring pin 14, a second electrode spring pin 15 and a third electrode spring pin 16 are installed inside the PCB connecting plate 5.

[0040] The working principle of Embodiment 1 is as follows: When in use, pull up the outer shell 2 and rotate it. When rotating 180 degrees to the left or right and then releasing the hand, the return spring 9 inside the bottom cover 6 will pull the outer shell 2 back to its original position, so that one side electrode of the outer shell 2 is connected to the PCB connection board 5, thereby realizing the dual - flavor switching. There is a first electrode 12 and a second electrode 13 on the left side of the cartridge body bracket 10, and two second electrodes 13 on the right side. Their function is to sense the oil volume of the first cartridge body 3 and the second cartridge body 11. When rotating the outer shell 2, when the side with the second electrode 13 touches the first electrode spring pin 14, the second electrode spring pin 15, and the third electrode spring pin 16 on the PCB connection board 5, it is sensed that the oil volume is in the second cartridge body 11; otherwise, it is the first cartridge body 3. The principle of identifying the first cartridge body 3 and the second cartridge body 11 is as follows: The first electrode 12 in the outer shell 2 can contact two electrode spring pins on the PCB connection board 5, one large and one small, and the second electrode 13 of the cartridge body can only contact one large electrode spring pin on the PCB connection board 5. When pulling up and rotating the outer shell 2, the first electrode 12 and the second electrode 13 in the outer shell 2 can simultaneously contact the first electrode spring pin 14, the second electrode spring pin 15, and the third electrode spring pin 16 in the PCB connection board 5, that is, the second cartridge body 11 is sensed. When the two second electrodes 13 in the outer shell 2 contact two electrode spring pins in the PCB connection board 5, the first cartridge body 3 is sensed.

[0041] Embodiment 2

[0042] Based on Embodiment 1, as Figure 5 shown, the bottom cover 6 further includes a sleeve plate 26, a vertical rod 19, a first spring 21, and a support cross - plate 20. The sleeve plates 26 are symmetrically and fixedly installed at the two top ends of the bottom cover 6. The first spring 21 and the vertical rod 19 are symmetrically and fixedly installed at the inner bottom end of the bottom cover 6, and the first spring 21 is located outside the vertical rod 19. The support cross - plate 20 is fixedly installed at the top end of the first spring 21. An insertion plate 25 is fixedly installed between the two support cross - plates 20. Four corners at the top end of the insertion plate 25 are fixedly installed with first racks 22. Two first gears 23 are symmetrically and rotatably installed at the two ends inside the bottom cover 6. The inner sides of the bottom cover 6 near the sleeve plates 26 are slidably inserted with special - shaped brackets 18. A first magnetic attraction piece 17 is fixedly installed at the top end of the special - shaped bracket 18, and a second rack 24 is fixedly installed at the bottom end of the special - shaped bracket 18;

[0043] When the special - shaped bracket 18 moves downward, it can drive the first rack 22 and the insertion plate 25 to move upward through the first gear 23.

[0044] As Figure 6 and Figure 7, the outer shell 2 further includes a covering device 27, an isolation device 28, a side-end device 29, and a synchronization device 30. The side-end device 29 is fixedly installed at the bottom of both ends of the outer shell 2. The covering device 27 is rotatably installed at the bottom of the side end of the side-end device 29 facing away from the outer shell 2. The isolation device 28 is slidably installed at the top of the side-end device 29. The synchronization device 30 is fixedly installed at the bottom of both ends of the outer shell 2 close to the side-end device 29, and can support the covering device 27 and the side-end device 29 to work.

[0045] As Figure 8 and 9 , the covering device 27 includes a protective cover 31 and a second gear 32. The second gear 32 is fixedly installed at the bottom of both ends of the protective cover 31. The isolation device 28 includes a displacement sleeve plate 33, an extended side plate 34, and a third rack 35. The displacement sleeve plate 33 is fixedly installed at the top of the extended side plate 34. The third rack 35 is symmetrically fixedly installed at the bottom end of the extended side plate 34. When the protective cover 31 rotates, it can drive the third rack 35 to displace upward through the second gear 32;

[0046] When the protective cover 31 rotates, it can drive the displacement sleeve plate 33 to displace up and down through the third rack 35.

[0047] As Figure 10 , the side-end device 29 includes a protective side plate 38, a second magnetic sheet 37, and an L-shaped air cylinder 40. The protective side plate 38 is fixedly installed at both ends of the second magnetic sheet 37. The L-shaped air cylinder 40 is fixedly installed on the inner side of the protective side plate 38 close to the second magnetic sheet 37. A second piston rod 39 can be slidably inserted into the bottom end of the L-shaped air cylinder 40, and a first piston rod 36 can be slidably inserted into the top end of the L-shaped air cylinder 40. The top end of the first piston rod 36 is connected and installed with an extended arm 42, and a limiting iron disk 41 is fixedly installed at the bottom end of the extended arm 42. The third rack 35 can slide inside the protective side plate 38, allowing the third rack 35 to displace upward;

[0048] When the second piston rod 39 displaces into the L-shaped air cylinder 40, it can drive the extended arm 42 and the limiting iron disk 41 to move upward.

[0049] As Figure 11 , the synchronization device 30 includes a support substrate 46 and a synchronization displacement plate 44. The synchronization displacement plate 44 is slidably inserted between the four support substrates 46. Second springs 43 are symmetrically fixedly installed on the side ends of the synchronization displacement plate 44. A lower-edge bracket 45 is fixedly installed at the bottom end of the synchronization displacement plate 44 away from the second springs 43. When the synchronization displacement plate 44 loses pressure, it is driven to reset by the second springs 43;

[0050] When the synchronization displacement plate 44 displaces towards the end close to the second springs 43, it can drive the second piston rod 39 to displace through the lower-edge bracket 45.

[0051] The first gear 23 meshes with the first rack 22 and the second rack 24. The second gear 32 is rotatably installed inside the bottom end of the protective side plate 38 away from the limit iron disc 41. The third rack 35 is slidably inserted inside the top end of the protective side plate 38 close to the second piston rod 39. The second spring 43 and the support base plate 46 are connected to the bottom ends of both ends of the housing 2. One end of the lower edge bracket 45 away from the support base plate 46 is connected to the second piston rod 39. The protective side plate 38 is fixedly installed at the bottom ends of both sides of the housing 2. The second gear 32 meshes with the third rack 35. A through hole adapted to the first magnetic sheet 17 and the limit iron disc 41 is opened at the center inside the sleeve plate 26. Heat dissipation holes are opened inside the bottom end of the bottom cover 6, and the insertion plate 25 is vertically aligned with the heat dissipation holes. Vertical sliding grooves adapted to the special-shaped bracket 18 are opened at the top ends of both sides of the bottom cover 6. A positioning groove is opened at the center of the side end of the displacement sleeve plate 33 away from the extension side plate 34. The inside of the L-shaped air cylinder 40 is provided in a hollow state, and a sealed cavity is formed between the second piston rod 39, the L-shaped air cylinder 40, and the first piston rod 36. Card slots are symmetrically opened inside the support base plate 46 close to the synchronous displacement plate 44, and key blocks are symmetrically fixedly installed at the top end and the bottom end of the synchronous displacement plate 44. The suction force between the first magnetic sheet 17 and the limit iron disc 41 is greater than the tension of the first spring 21. There is a 1 cm gap between the bottom end of the insertion plate 25 and the inner bottom end of the bottom cover 6.

[0052] When implementing this embodiment, during use, before the housing 2 needs to rotate, the protective cover 31 can be rotated downward. When the protective cover 31 is rotated downward, the second gear 32 can be driven to rotate. Moreover, since the third rack 35 meshes with the second gear 32, when the second gear 32 rotates, the third rack 35 can be driven to move upward. At the same time, when the third rack 35 moves upward, the displacement sleeve plate 33 and the extension side plate 34 can be driven to move upward simultaneously. When the protective cover 31 is rotated downward to a vertical state, the displacement sleeve plate 33 can move upward to be flush with the top end of the cigarette holder body 1, preventing external objects from contacting the cigarette holder body 1 when the housing 2 rotates.

[0053] The synchronous displacement plate 44 can be pressed towards one end close to the second spring 43, so that the synchronous displacement plate 44 can drive the second piston rod 39 into the interior of the L-shaped air cylinder 40 through the lower edge bracket 45. Thus, the first piston rod 36 can drive the extension arm 42 to move upward, enabling the limit iron disk 41 to move upward from the interior of the sleeve plate 26 to the limit position. Consequently, the bottom end of the limit iron disk 41 can be flush with the top end of the sleeve plate 26. At the same time, when the outer shell 2 is in contact with the bottom cover 6, the limit iron disk 41 can be adsorbed and attached to the first magnetic sheet 17. When the limit iron disk 41 moves upward, it can drive the first magnetic sheet 17 and the special-shaped bracket 18 to move upward. Thus, the second rack 24 can move upward along the surface of the first gear 23. When the second rack 24 moves upward, it can drive the first rack 22 to move downward through the first gear 23. Thus, the insertion plate 25 can be inserted into the heat dissipation groove at the bottom end inside the bottom cover 6, and the dust accumulated inside the heat dissipation groove can be pushed out, improving the heat dissipation performance inside the bottom cover 6;

[0054] The outer shell 2 can be rotated 180°. When the outer shell 2 rotates, the limit iron disk 41 can be separated from the first magnetic sheet 17. At this time, the first spring 21 will drive the support cross plate 20 and the insertion plate 25 to move upward and reset. Thus, the insertion plate 25 can be removed from the heat dissipation groove at the bottom end inside the bottom cover 6, facilitating the entry of external air into the interior of the bottom cover 6. Subsequently, when the insertion plate 25 moves upward, it can drive the first rack 22 to move upward along the surface of the first gear 23, enabling the second rack 24 to drive the first magnetic sheet 17 to move downward and reset. Subsequently, when the outer shell 2 rotates 180°, the limit iron disk 41 can be vertically aligned with the sleeve plate 26 again, and the synchronous displacement plate 44 can be released. Due to the elasticity of the second spring 43, the synchronous displacement plate 44 will be driven to move outward and reset;

[0055] When the synchronous displacement plate 44 resets, it can drive the second piston rod 39 to move out of the interior of the L-shaped air cylinder 40 through the lower edge bracket 45, enabling the first piston rod 36 to move downward and reset, causing the limit iron disk 41 to be inserted into the interior of the sleeve plate 26 again. Thus, the limit iron disk 41 can be attached to the first magnetic sheet 17 again. Subsequently, the protective cover 31 can be rotated upward to reset, enabling the second gear 32 to drive the third rack 35 to move downward. And when the protective cover 31 rotates to be vertically upward, it can be adsorbed and attached to the second magnetic sheet 37, preventing the protective cover 31 from rotating downward again. At the same time, when the third rack 35 moves downward, the displacement sleeve plate 33 can move downward simultaneously to be in contact with the top surface of the outer shell 2, facilitating the user's lips to contact the cigarette holder body 1.

[0056] When the device is in use, when the insertion plate 25 is 1 centimeter away from the heat dissipation groove at the inner bottom end of the bottom cover 6, it can avoid the insertion plate 25 blocking the heat dissipation groove of the bottom cover 6. Moreover, when the insertion plate 25 moves downward to the limit position, it can penetrate into the inside of the heat dissipation groove, so as to avoid dust remaining inside the heat dissipation groove. At the same time, when the protective cover 31 is adsorbed and attached to the second magnetic sheet 37, the synchronous displacement plate 44 can be protected and isolated, so as to avoid the user accidentally touching the synchronous displacement plate 44. And, by the sliding of the key on the top and bottom ends of the synchronous displacement plate 44 in the card slot inside the support substrate 46, the synchronous displacement plate 44 can be supported to move linearly. At the same time, a plastic gasket is fixedly installed on the side end of the protective side plate 38 facing away from the L-shaped air cylinder 40, and the user can hold the protective side plate 38 to increase the friction force and avoid the phenomenon of slipping when the user takes the device, thus completing the work.

[0057] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
