Detailed implementation manners

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0034] The present invention provides as Figures 1-9An electronic cigarette structure facilitating the replacement of a cartridge, comprising a cigarette rod 1 and a cartridge 2. In the structure, the cigarette rod 1 is of a cylindrical structure, and a fixing mechanism 3 is provided inside the cigarette rod 1. The fixing mechanism 3 in the structure includes a fixing sleeve 31, an electromagnet 33, an electromagnet 32, an elastic support assembly 34, an anti-blocking assembly 37 and a linkage assembly 38. The electromagnet 33 is sleeved and fixed at the lower part of the fixing sleeve 31. Symmetric positioning grooves 311 are formed on the inner wall of the fixing sleeve 31. A positioning groove 312 is formed at one end of the positioning groove 311 close to the electromagnet 33. The positioning groove 312 communicates with the positioning groove 311. The cross-sectional shapes of the positioning groove 311 and the positioning groove 312 are both arc-shaped. The positioning groove 311 and the positioning groove 312 are used to position the positioning block 211, so as to realize the rapid positioning of the cartridge 2. A lightweight ring plate 35 is movably sleeved outside the fixing sleeve 31 in the structure. A magnetic attraction member 36 is installed on one side of the lightweight ring plate 35 close to the electromagnet 33. The magnetic attraction member 36 is of an annular structure. The elastic support assembly 34 and the anti-blocking assembly 37 are both arranged between the magnetic attraction member 36 and the electromagnet 33. The inner and outer sides of the magnetic attraction member 36 can be a strong magnetic sheet and rubber, or a strong magnetic sheet and silica gel, and the rubber is used to protect the strong magnetic sheet;

[0035] In the structure, the number of the linkage assemblies 38 is set to two. The linkage assemblies 38 are symmetrically arranged. Each linkage assembly 38 includes a wedge-shaped block 381 and a wedge-shaped block 382. The inclined surface of the wedge-shaped block 381 is always in contact with the inclined surface of the wedge-shaped block 382. The wedge-shaped block 381 is arranged on one side of the lightweight ring plate 35 away from the electromagnet 33 and is fixedly connected to the lightweight ring plate 35. A plug rod 385 is installed at the center of the side of the wedge-shaped block 382 away from the wedge-shaped block 381. A spring 383 and a mounting ring plate 384 are sleeved on the outer wall of the plug rod 385. One end of the spring 383 is fixedly connected to the mounting ring plate 384. In the structure, the cartridge 2 is composed of an atomizer 21, an oil storage chamber and a cigarette holder 22. Symmetric positioning blocks 211 matched with the positioning groove 311 and the positioning groove 312 are installed on the outer wall of the atomizer 21. The positioning blocks 211 are arranged at one end away from the oil storage chamber. A groove matched with the plug rod 385 is formed on the outer arc surface of the positioning block 211. The added positioning blocks 211 on the cartridge 2 can quickly position the cartridge 2 and make the installation more convenient.

[0036] Among them, a sliding hole 313 with a T-shaped cross-section is formed outside the positioning groove 312 in the structure. The sliding hole 313 is in moving fit with the plug rod 385. The mounting ring plate 384 is fixedly glued in the sliding hole 313. Through the moving fit between the plug rod 385 and the sliding hole 313, the position of the plug rod 385 can be effectively prevented from shifting. The sliding hole 313 with a T-shaped cross-section is beneficial to fixing the mounting ring plate 384.

[0037] In addition, a plurality of weight-reducing holes 351 are formed in the lightweight ring plate 35 of the structure. The weight-reducing holes 351 are evenly distributed along the circumference on the lightweight ring plate 35. The provided weight-reducing holes 351 can reduce the weight of the lightweight ring plate 35, and thus can reduce the weight of the entire electronic cigarette.

[0038] In order to control the power on and off of the electromagnet, the following optimizations are made. A partition 17 is installed inside the cigarette rod 1 of the structure. The partition 17 is used to support and fix the sleeve 31. A control board 15 is installed on one side of the partition 17. The control board 15 can be a control board of the STM series or a specially developed control module for circuit control. A power supply battery 14 is installed on the side of the control board 15 away from the partition 17. The electronic cigarette is powered by the power supply battery 14. The power supply battery 14 is a rechargeable battery, which can be a lithium battery. The power output end of the power supply battery 14 is electrically connected to the power input end of the control board 15 through a cable. And the fixed sleeve 31 is arranged on the side away from the control board 15 and is fixedly connected to the partition 17. The electromagnet two 32 is arranged on the side away from the partition 17 and is fixedly connected to the inner wall of the cigarette rod 1. The electromagnet two 32 is electrically connected to the output end of the control board 15 through a cable.

[0039] In the above solution, the following improvements are made. A switch one 12 and a switch two 16 are installed on the outer wall of the cigarette rod 1 of the structure. The switch one 12 and the switch two 16 are respectively electrically connected to the control board 15 and the electromagnet one 33 through cables. The switch one 12 and the switch two 16 respectively control the power supply and the electromagnet one 33.

[0040] Among them, two electrodes A 18 are embedded in the partition 17 of the structure. The two electrodes A 18 are symmetrically arranged. And an electrode B 212 is arranged at the end of the atomizer 21 away from the oil storage chamber. The electrode B 212 is electrically connected to the electrode A 18. After the power supply is turned on, through the mutual contact of the electrode B 212 and the electrode A 18, the atomizer 21 can be powered on. The powered atomizer 21 works to atomize the e-liquid in the oil storage chamber.

[0041] In addition, a sealing end cap 11 is installed at the end of the cigarette rod 1 away from the cartridge 2. A charging socket 111 is embedded at the center of the sealing end cap 11. The output end of the charging socket 111 is electrically connected to the input end of the power supply battery 14. The charging socket 111 is used to charge the power supply battery 14.

[0042] Specifically, by pressing the switch one 12, the power supply is turned on. The electronic cigarette is powered by the power supply battery 14. At this time, the electromagnet two 32 is powered on through the control board 15. At the same time, since the electrode B 212 and the electrode A 18 are in mutual contact, the atomizer 21 will be powered on and work. The atomizer 21 is used to atomize the e-liquid in the oil storage chamber. The atomized e-liquid is discharged through the mouthpiece 22. After use, turn off the switch one 12, and the device will stop working.

[0043] To avoid the blockage of the air inlet by particulate matters such as dust in the air, the following optimizations are made. The number of anti-blocking components 37 in the structure is set to four. The anti-blocking components 37 and the elastic support components 34 are installed in an alternating manner, that is, one anti-blocking component 37 is arranged between two elastic support components 34. Each anti-blocking component 37 includes a lightweight plugging block 371 and a fixing rod 373. The lightweight plugging block 371 can be made of a lightweight material such as rubber, which can reduce the overall weight of the electronic cigarette. A through hole is provided on the lightweight plugging block 371, and the through hole is in movable fit with the fixing rod 373. An annular permanent magnet 372 is provided at one end of the through hole. The annular permanent magnet 372 is embedded in the lightweight plugging block 371 and does not protrude from the lightweight plugging block 371. One end of the fixing rod 373 in the structure passes through the annular permanent magnet 372 and the through hole and is fixedly connected to the electromagnet 33. The fixing rod 373 is used for guiding and can effectively prevent the position of the lightweight plugging block 371 from shifting. The height of the fixing rod 373 is the same as that of the mounting frame 341. A second spring 374 is sleeved on the outer wall of the other end of the fixing rod 373. The second spring 374 plays a resetting role, is also used for buffering, and can also support the lightweight ring plate 35. The two ends of the second spring 374 are respectively fixedly connected to the annular permanent magnet 372 and the magnetic attracting member 36. Four air vents 13 corresponding to the lightweight plugging blocks 371 are provided on both the cigarette rod 1 and the fixed sleeve 31. The provided air vents 13 are used to allow external air to enter the fixed sleeve 31, and then enter the atomizer 21 through the air inlet on the cartridge 2.

[0044] Specifically, the attractive force generated by the energized electromagnet 32 causes the annular permanent magnet 372 to drive the lightweight plugging block 371 to move towards the side close to the magnetic attracting member 36, exposing the air vents 13. At the same time, the annular permanent magnet 372 compresses the second spring 374. Then, external air can flow into the fixed sleeve 31 through the air vents 13 and then enter the atomizer 21 through the air inlet. After use, that is, after turning off the switch 12, the electromagnet 32 is powered off and the attractive force disappears. Using the elastic force of the second spring 374, the lightweight plugging block 371 is reset to block the air vents 13, thereby effectively avoiding the situation where particulate matters such as dust in the external environment block the air inlet.

[0045] In order to stably support the lightweight ring plate 35, the following improvements are made. The number of elastic support components 34 in the structure is set to four. Each elastic support component 34 includes a mounting bracket 341, and the mounting bracket 341 is of a U-shaped structure. The mounting brackets 341 are evenly distributed along the circumference on the first electromagnet 33. A pressing plate 342 is slidably connected inside the mounting bracket 341. Connecting rods 343 and the third spring 344 are respectively installed at both ends of the pressing plate 342. The third spring 344 is used to support the lightweight ring plate 35, can also buffer, and play a reset role. The ends of the connecting rod 343 and the third spring 344 away from the pressing plate 342 are respectively fixedly connected to the magnetic attraction member 36 and the mounting bracket 341. When the magnetic attraction member 36 drives the lightweight ring plate 35 to move, it will cause the connecting rod 343 to drive the pressing plate 342 to compress the third spring 344, and use the third spring 344 for buffering. After the first electromagnet 33 is powered off, the attraction disappears, and the elastic force of the third spring 344 is used to reset the lightweight ring plate 35. After resetting, the third spring 344 is used to support the lightweight ring plate 35.

[0046] Among them, two limiting through grooves 3411 are opened on the mounting bracket 341 in the structure. The two limiting through grooves 3411 are symmetrically arranged. And sliding blocks 3421 are symmetrically installed on the outer side of the pressing plate 342 in the structure. The sliding blocks 3421 are slidably connected with the limiting through grooves 3411. The sliding fit between the sliding blocks 3421 and the limiting through grooves 3411 plays a guiding and limiting role, can limit the pressing plate 342, and can also effectively prevent the position of the pressing plate 342 from shifting.

[0047] The working principle of the present invention:

[0048] When the cartridge 2 needs to be replaced, first press switch two 16 to energize the electromagnet one 33. The attraction generated by the energized electromagnet one 33 causes the magnetic attraction member 36 to drive the lightweight ring plate 35 to move towards the electromagnet one 33. The lightweight ring plate 35 is used to drive the wedge-shaped block one 381, and at the same time, the elastic force of the spring one 383 causes the wedge-shaped block two 382 to drive the insertion rod 385 to disengage from the groove on the positioning block 211. Then, rotate the cartridge 2 counterclockwise until it cannot move, and then the cartridge 2 can be pulled outwards to complete the disassembly of the cartridge 2. During installation, align the positioning block 211 with the first positioning groove 311 so that the cartridge 2 can be smoothly inserted into the fixed sleeve 31 until the cartridge 2 cannot move further. Then, rotate the cartridge 2 clockwise until it cannot move further. After that, press switch two 16 to cut off the power supply of the electromagnet one 33. At this time, the attraction disappears. Using the elastic force of the spring three 344, the lightweight ring plate 35 is reset, and then the wedge-shaped block one 381 is reset. The wedge-shaped block one 381 is used to squeeze the wedge-shaped block two 382, so that the wedge-shaped block two 382 drives the insertion rod 385 to insert into the groove while squeezing the spring one 383 to fix the cartridge 2. At this time, the electrode B 212 is in contact with the electrode A 18. When using the electronic cigarette, press switch one 12 to turn on the power supply, and the power supply battery 14 is used to supply power to the electronic cigarette. At this time, the electromagnet two 32 is energized through the control board 15. The attraction generated by the energized electromagnet two 32 causes the annular permanent magnet 372 to drive the lightweight plugging block 371 to move towards the side close to the magnetic attraction member 36, exposing the ventilation hole 13. At the same time, the annular permanent magnet 372 squeezes the spring two 374. Then, the external air can flow into the fixed sleeve 31 through the ventilation hole 13 and then enter the atomizer 21 through the air inlet hole. At the same time, since the electrode B 212 is in contact with the electrode A 18, the atomizer 21 will be powered on to work. The atomizer 21 is used to atomize the e-liquid in the oil storage chamber, and the atomized e-liquid is discharged through the mouthpiece 22. After use, turn off switch one 12, and the device will stop working. The electromagnet two 32 is powered off, and the attraction disappears. Using the elastic force of the spring two 374, the lightweight plugging block 371 is reset to block the ventilation hole 13.

[0049] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
