Description

Technical Field

[0001] The utility model relates to the technical field of cigarette substitutes, in particular to a rotary cartridge-changing electronic cigarette. Background Art

[0002] An electronic atomizer is an electronic product that mimics cigarettes and can atomize tobacco oil into smoke for users to inhale. Due to the similar taste and convenience of inhalation as cigarettes, electronic atomizers have been rapidly promoted and used.

[0003] In addition to flavors similar to tobacco, different flavors of essence can be added to the e-liquid to make e-liquids with different flavors, giving consumers more choices.

[0004] Existing electronic atomizer devices generally consist of a battery-powered main unit and an atomizer. The atomizer is the smoke-generating part of the electronic atomizer device, storing tobacco oil. High temperatures cause the oil to atomize and form smoke. The battery-powered main unit serves as the control center and power supply for the electronic atomizer device. Typically, one battery-powered main unit is paired with one atomizer. When the tobacco oil in the atomizer runs out or when the flavor needs to be changed, the atomizer needs to be removed and replaced. There have also been a few attempts to pair a single battery-powered main unit with multiple atomizers, but these typically involve rotating the entire atomizer, excluding the mouthpiece, or by rotating the mouthpiece, or by opening an adjustment window on the atomizer housing and rotating it through the adjustment window to achieve the desired effect. However, current adjustment methods either compromise the sealing performance between the mouthpiece and the oil tank, or result in jerky operation and inconvenient adjustment. Utility Model Content

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] See also Figure 1 , is a schematic structural diagram of a rotary cartridge-changing electronic cigarette in one embodiment.

[0029] A rotary cartridge-changing electronic cigarette includes an atomizer 10, a battery main unit 20, and a housing 30. The atomizer 10 is the electronic cigarette's aerosol generating device, which is used to generate heat when powered, so that the tobacco liquid in the atomizer 10 forms an aerosol for the user to inhale; the battery main unit 20 is the electronic cigarette's control center and power supply center. The battery provides electrical energy to the entire electronic cigarette circuit, so that the control center is powered to control the various components in the circuit, so that the atomizer 10 can be powered and heated; the atomizer 10 is compatible with the battery main unit 20, and both the atomizer 10 and the battery main unit 20 are accommodated in the housing 30.

[0030] For details, please refer to Figures 2 to 5 The housing 30 is provided with a nozzle 32, and the atomizer 10 is connected to the nozzle 32. The atomizer 10 includes at least two cartridges 12. During atomization, each cartridge 12 can be electrically connected to the battery host 20 for atomization, or two or more cartridges 12 can be electrically connected to the battery host 20 for atomization. The atomizer 10 also includes a cartridge replacement mechanism 40. The cartridge replacement mechanism 40 is fixedly disposed within the housing 30 and is located at the bottom of the atomizer 10. The cartridge replacement mechanism 40 includes a rotating assembly 42 and a driving assembly 44. The rotating assembly 42 is fixed to the atomizer 10, and the cartridge 12 is accommodated in the rotating assembly 42. The driving assembly 44 is arranged at an angle to the rotating assembly 42, and one end of the driving assembly 44 extends out of the wall of the housing 30.

[0031] The rotary single-change electronic cigarette is provided with at least two cigarette cartridges 12. By setting a cartridge changing mechanism 40 composed of a rotating component 42 and a driving component 44, the cigarette cartridge 12 is set in the rotating component 42, and the driving component 44 is set at an angle to the rotating component 42. The driving component 44 can be operated to drive the rotating component 42 to rotate, and the cigarette cartridge 12 in the rotating component 42 can be driven to rotate by a certain angle, so that the rotation replacement of the cigarette cartridge 12 can be achieved; there is no need to disassemble and replace the cigarette cartridge 12, and there is no need to rotate the suction nozzle 32 or the rotating shell 30, and its excellent sealing performance is not affected; the cartridge can be replaced by gently pressing the button 4432, and the operation is smooth and the adjustment is convenient.

[0032] In this embodiment, please refer to Figures 2 to 5 The rotating assembly 42 includes a rotating disk 421, a rotating shaft 424, and a rotating shell 425. A accommodating chamber 427 for accommodating the cigarette cartridge 12 is formed in the rotating shell 425 via a partition 426. The ends of the rotating shaft 424 are respectively fixed to the rotating shell 425 and the rotating disk 421. The rotating disk 421 drives the rotating shell 425 to rotate via the rotating shaft 424. During use, the driving assembly 44 moves when subjected to force, driving the rotating disk 421 to rotate, and at the same time, driving the rotating shell 425 to rotate via the rotating shaft 424. The cigarette cartridge 12 in the rotating shell 425 rotates synchronously with the rotating shell 425. The electrodes of the electronic cigarette are fixed and do not move synchronously, thus achieving the purpose of replacing the cigarette cartridge 12.

[0033] In one embodiment, the rotating shaft 424 and the rotating shell 425 are integrally formed, and the rotating shaft 424 protrudes from the bottom of the rotating shell 425. Once the rotating shaft 424 is plugged into and positioned with the rotating disk 421, the rotating disk 421 can drive the rotating shaft 424 and the rotating shell 425 to rotate. The integral molding method facilitates simplified processing and assembly processes.

[0034] In another embodiment, the rotating shaft 424, the rotating housing 425, and the rotating disk 421 are all detachable. Specifically, the rotating shaft 424, the rotating housing 425, and the rotating disk 421 are manufactured and assembled as three separate components. A first insertion hole 422 and a second insertion hole are respectively provided in the center of the rotating disk 421 and the center of the rotating housing 425. The partition between the second insertion hole and the accommodating cavity 427 does not interfere with each other. The ends of the rotating shaft 424 are respectively inserted and fixed into the first insertion hole 422 and the second insertion hole. This detachable configuration of the rotating shaft 424 can reduce production requirements and improve product quality.

[0035] Preferably, the number of cavities 427 is an even number, preferably four, six, or eight, and each cavity 427 is provided with an air inlet 428 at the bottom thereof that is in communication with the cigarette cartridge 12 contained therein. Providing an even number of cavities 427 is beneficial for maintaining good symmetry and drive balance between the rotating assembly 42 and the driving assembly 44. The cigarette cartridges 12 in the atomizer 10 can be filled with different flavors of e-liquid to change the flavor; or they can be filled with the same e-liquid to increase the amount of e-liquid, so that a relatively small amount of e-liquid is injected into each cigarette cartridge 12, which is beneficial for ensuring that the e-liquid is clean and pollution-free. Too few cavities will not achieve the desired effect, and too many cavities will result in an oversized electronic cigarette. Of course, if necessary, the corresponding number can be designed accordingly. The fact that each cavity 427 is provided with an air inlet 428 at the bottom thereof that is in communication with the cigarette cartridge 12 contained therein facilitates the individual powering and atomization of each cigarette cartridge 12.

[0036] In this embodiment, please refer to Figures 2 to 5The driving assembly 44 includes a first push rod assembly 441 and a second push rod assembly 445. A clearance hole 34 is opened on the wall of the outer shell 30. The first push rod assembly 441 is fixed in the outer shell 30, and one end is embedded in the clearance hole 34. The second push rod assembly 445 is fixed in the internal space of the outer shell 30, and the two ends of the second push rod assembly 445 respectively contact the first push rod assembly 441 and the rotating disk 421. The second push rod assembly 445 is arranged perpendicular to the rotating disk 421. A first push rod assembly 441 and a second push rod assembly 445 are provided perpendicular to each other, and both the first push rod assembly 441 and the second push rod assembly 445 are preset with a movement direction, that is, the first push rod assembly 441 and the second push rod assembly 445 can only move along the set direction and range. When power is applied at the position where the first push rod assembly 441 extends out of the clearance hole 34, the first push rod assembly 441 can be moved. Under the squeeze and drive of the first push rod assembly 441, the second push rod assembly 445 synchronously moves in the preset direction and contacts the rotating disk 421. Then, the driving assembly 44 can drive the rotating disk 421 to rotate, thereby rotating the rotating shell 425 to replace the cigarette cartridge 12. Of course, the vertical arrangement of the first push rod assembly 441 and the second push rod assembly 445 is the best choice. The second push rod assembly 445 is coaxially arranged with the rotating assembly 42. The clearance hole 34 is opened on the side of the shell 30, and one end of the first push rod assembly 441 extends out of the side wall of the shell 30. If the tilt settings are at other angles between the two, as long as the same principle is used, the same effect can be achieved, and it can also be flexibly used according to the layout of the internal structure of the electronic cigarette.

[0037] Among them, the first push rod assembly 441 includes a bracket 442, a first push rod 443 and a first reset element 444. The bracket 442 is fixed to the inside of the housing 30. The bracket 442 is provided with a limiting platform 4422 and a first limiting boss 4424 for supporting and limiting the first push rod 443. The first push rod 443 is placed between the bracket 442 and the second push rod assembly 445, and the first push rod 443 is arranged perpendicular to the second push rod assembly 445. The first push rod 443 is provided with a press key 4432 The push button 4432 is movably embedded in the clearance hole 34. The clearance groove 4434 and the second limiting protrusion 4436 are both located on the back of the push button 4432. The first reset element 444 is accommodated in the clearance groove 4434, with its two ends respectively contacting the first limiting protrusion 4424 and the second limiting protrusion 4436. Pressing the push button 4432 can drive the first push rod 443 to reciprocate between the limiting platform 4422 and the clearance hole 34. The bracket 442 cooperates with the clearance hole 34 to help limit the extension and retraction of the first push rod 443 along a preset motion trajectory. The limiting platform 4422 can limit the travel of the first push rod 443, that is, the first push rod 443 can move along the motion trajectory from the clearance hole 34 to the limiting platform 4422, avoiding the situation where the preset travel is exceeded and the push rod 443 cannot rebound. The push button 4432 of the first push rod 443 extends out of the housing 30 through the clearance hole 34, making it easy for the user to press it. A clearance groove 4434 is provided for accommodating the first reset element 444. At this time, the two ends of the first reset element 444 respectively abut the limit plate 4422 of the bracket 442 and the back of the push button 4432. When the first push rod 443 is moved by applying force on the push button 4432, the first reset element 444 is compressed. When the magazine is reloaded and the pressure on the push button 4432 disappears, the first reset element 444 releases the pressure, pushing the push button 4432 toward the clearance hole 34, thereby resetting the first push rod 443. The cycle continues. The first and second limit bosses 4424 and 4436 can be respectively inserted into the two ends of the first reset element 444, fixing the first reset element 444 in place and preventing the reset function of the first reset element 444 from failing due to tilting or twisting. Of course, the first limiting boss 4424 and the second limiting boss 4436 can also be configured as a hollow structure, and both ends of the first reset element 444 are respectively inserted into the hollow structure and fixed.

[0038] Among them, the way in which the bracket 442 limits the first push rod 443 can be: the bracket 442 and the first push rod 443 are respectively provided with one of the sliding grooves and the other of the guide rails, and the sliding grooves and the guide rails are adapted to ensure that the first push rod 443 slides along the preset track on the bracket 442.

[0039] Preferably, see Figure 5The push button 4432 is also provided with a limiting flange 4437. The limiting flange 4437 is protruding from the edge of the push button 4432 and cooperates with the clearance hole 34 inside the housing 30 to prevent the push button 4432 from falling out of the clearance hole 34. The push button 4432 and the clearance hole 34 are adapted in size. The limiting flange 4437 is provided on the edge of the push button 4432 and is definitely larger than the clearance hole 34. Because the limiting flange 4437 is located inside the housing 30, it can ensure that the push button 4432 extends out of the clearance hole 34 but does not fall out of the clearance hole 34, ensuring smooth pressing and rebounding.

[0040] For further information, see Figures 2 to 5 The second push rod assembly 445 includes a limit frame 446, a second push rod 447 and a second reset element 448. The limit frame 446 is fixed to the inside of the shell 30. The limit frame 446 is provided with a limit hole 4462, a first limit groove 4464 and an accommodating cavity 4466. The second push rod 447 is inserted and fixed in the limit hole 4462, and both ends extend out of the limit hole 4462. The second push rod 447 can be extended and retracted along the limit hole 4462. The outer wall of the second push rod 447 is provided with a second limit groove 4472. The second reset element 448 is accommodated in the accommodating cavity 4466. The second reset element 448 is sleeved on the second push rod 447, and its two ends respectively contact the first limit groove 4464 and the second limit groove 4472. The two ends of the second push rod 447 respectively contact the first push rod 443 and the rotating disk 421. The limiting frame 446 helps to limit the extension and retraction of the second push rod 447 along the motion trajectory of the preset limiting hole 4462. As the second push rod 447 extends and retracts, the rotating disk 421 can rotate and pause, thereby driving the rotating shell 425 to rotate to complete the reloading. The second reset element 448 is placed in the accommodating cavity 4466. When the second push rod 447 is squeezed out of the limiting frame 446 by the first push rod 443, the second reset element 448 is squeezed. When the reloading is completed, the pressure on the second push rod 447 disappears, and the second reset element 448 releases the pressure, pushing the second push rod 447 back to the unstressed state, thereby resetting the second push rod 447. The cycle continues. The two ends of the second reset element 448 can be respectively inserted into the first limiting groove 4464 and the second limiting groove 4472, so that the position of the second reset element 448 is fixed, avoiding the reset function failure of the second reset element 448 due to tilting or twisting. Of course, the first limiting groove 4464 and the second limiting groove 4472 can also be set as limiting bosses, and the two ends of the second reset element 448 are respectively sleeved on the limiting bosses and fixed.

[0041] For details, please refer to Figure 2 、 Figure 5The first push rod 443 is provided with a first inclined platform 4438, and the second push rod 447 is provided with a second inclined platform 4474. The first inclined platform 4438 conflicts with the second inclined platform 4474, and pressing the push button 4432 causes the first inclined platform 4438 to move relative to the second inclined platform 4474, and the second push rod 447 moves toward the cigarette cartridge 12; at least two oblique teeth 423 are provided at the bottom of the rotating disk 421, and the second push rod 447 conflicts with the oblique teeth 423. The first push rod 443 and the second push rod 447 are arranged vertically, and the contact point between the two is abutted by the first inclined platform 4438 and the second inclined platform 4474 which are respectively arranged. When an external force is applied at the press key 4432, the first push rod 443 moves along the motion trajectory, and the position of the first inclined platform 4438 also moves relatively, so that the lower inclined surface originally in contact with the second inclined platform 4474 moves to a higher inclined surface, so that the second push rod 447 is abutted in the direction of the cigarette cartridge 12, and gradually moves along the limiting hole 4462 toward the cigarette cartridge 12, abutting the oblique teeth 423 of the rotating disk 421. Synchronously, the second top rod 447 is in contact with the tooth top of the bevel tooth 423 when it is not under force. As the second top rod 447 moves, the second top rod 447 gradually slides along the inclined surface of the bevel tooth 423 to the tooth root of the bevel tooth 423 and is positioned. At this time, since the radial position of the second top rod 447 has not changed, the position where the second top rod 447 is in contact moves from the tooth top of the rotating disk 421 to the tooth root. This process drives the rotation of the rotating disk 421, thereby realizing the rotation of the rotating shell 425 and the cigarette cartridge 12 in the rotating shell 425, and realizing cartridge replacement.

[0042] More specifically, the first push rod 443 and the second push rod 447 are respectively provided with two matching first ramps 4438 and two second ramps 4474. The number of beveled teeth 423 provided on the rotating disk 421 matches the number of cigarette cartridges 12. The configuration of two sets of first ramps 4438 and second ramps 4474 facilitates maintaining a good driving balance between the first push rod assembly 441 and the second push rod assembly 445, which can ensure smoother and smoother cartridge replacement. The number of beveled teeth 423 provided on the rotating disk 421 matches the number of cigarette cartridges 12.

[0043] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
