Description

Technical Field

[0001] This utility model belongs to the field of electronic cigarette technology, specifically relating to an electronic cigarette with easy-to-replace cartridges. Background Technology

[0002] In the current e-cigarette market, replaceable cartridge models have become one of the mainstream designs due to their advantages such as "changing flavors as needed and reducing usage costs". Among them, traditional e-cigarettes that are easy to replace cartridges mostly adopt a magnetic installation structure, that is, the cartridge and the e-cigarette body are quickly disassembled and assembled by the attraction force of the built-in magnet. Although this greatly simplifies the user's operation process of replacing cartridges, there are still obvious stability defects in actual use scenarios.

[0003] Specifically, magnetic installation relies solely on the magnetic attraction between the cartridge and the device to maintain the connection, without any additional mechanical limiting or locking structures. When users place the e-cigarette in their bags, pockets, or other personal spaces, the device is easily subjected to external forces due to daily activities (such as pressure from limbs when walking or sitting) or collisions with objects (such as the impact of keys or mobile phones on the device). If this impact force exceeds the magnetic attraction force, the cartridge can easily loosen or even fall off the device. This can not only lead to e-liquid leakage from the cartridge, contaminating personal belongings, but also damage the cartridge interface and oxidation of the device contacts, affecting the normal use of the e-cigarette. Furthermore, there is a risk of the cartridge falling out and being lost, increasing the user's additional usage costs and resulting in a poor overall user experience.

[0004] To address the aforementioned issues, this application proposes an electronic cigarette with easily replaceable cartridges. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] Please see Figures 1-6 The present invention provides the following technical solution: an electronic cigarette that is easy to replace cartridges, including a cigarette body 1, a battery compartment 2 and a cartridge body 5. The battery compartment 2 is located at the lower end of the cigarette body 1. The upper end of the cigarette body 1 is provided with an installation port 10 for placing the cartridge body 5. The upper inner wall of the cigarette body 1 is provided with a plurality of longitudinal sliding grooves 11 and transverse sliding grooves 12 distributed along the circumferential direction. The longitudinal sliding grooves 11 and transverse sliding grooves 12 are connected. The outer surface of the cartridge body 5 is provided with multiple limiting blocks 17, which can slide from the longitudinal sliding groove 11 into the transverse sliding groove 12. It also includes a sealing element 9. A vent 8 is provided on one side of the cigarette body 1. The sealing element 9 is slidably installed in the vent 8 to block the vent 8.

[0019] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, a mouthpiece 6 is provided at the top of the cigarette cartridge body 5, and a rubber stopper 7 is inserted on the mouthpiece 6. The mouthpiece 6 can be used after removing the rubber stopper 7. The rubber stopper 7 has a sealing function to prevent dust and impurities from entering the mouthpiece 6 and affecting its use, and is highly practical.

[0020] Preferably, by Figures 1 to 4 As shown, in this embodiment, the cigarette body 1 is provided with a charging interface 3 and a switch button 4. Inside the cigarette body 1, there is a pair of contact copper sheets 13 and a pair of positive magnetic blocks 14. At the bottom of the cigarette cartridge body 5, there is a pair of conductive copper sheets 18 and a pair of negative magnetic blocks 19. The contact copper sheets 13 are connected to the conductive copper sheets 18, and the positive magnetic blocks 14 are connected to the negative magnetic blocks 19. When the limiting block 17 is embedded in the longitudinal sliding groove 11, the cartridge body 5 can be rotated clockwise to slide the limiting block 17 into the transverse sliding groove 12. At this time, the positive magnetic block 14 and the negative magnetic block 19 are attracted to each other, and the contact copper sheet 13 is connected to the conductive copper sheet 18. During the installation process, the limiting blocks 17 are aligned with the longitudinal sliding groove 11, and the cartridge body 5 is inserted into the installation port 10. When it is fully inserted, the limiting block 17 reaches the end of the longitudinal sliding groove 11. The cartridge body 5 is then rotated clockwise, and the limiting block 17 will slide into the transverse sliding groove 12. When the limiting block 17 slides to its end, the user will feel the attraction between the positive magnetic block 14 and the negative magnetic block 19, indicating that the installation is complete. At the same time, the corresponding conductive contact copper sheet 13 and conductive copper sheet 18 are connected. Through the limiting effect of the limiting block 17 and the horizontal sliding groove 12, the cartridge body 5 is stably installed, reducing the risk of falling off. In addition, the attraction between the positive magnetic block 14 and the negative magnetic block 19 also reduces the probability of the cartridge body 5 rotating in the opposite direction, further improving the installation stability and practicality.

[0021] Preferably, by Figure 1 , Figure 2 and Figure 6 As shown in this embodiment, the interior of the cigarette rod body 1 is provided with a ventilation cavity 15 and a ventilation hole 16. The ventilation cavity 15 is connected to the ventilation hole 16, and the ventilation hole 16 is connected to the ventilation port 8.

[0022] The cigarette body 1 has a sliding cavity 22. The sealing element 9 includes a sealing plate 23 that is slidably installed in the sliding cavity 22. One end of the sealing plate 23 is provided with a sealing button 24. The sealing button 24 can move within the range of the air vent 8, and the sealing plate 23 can move within the range of the sliding cavity 22.

[0023] The main body 1 of the e-cigarette has a groove 20, and a silicone ring 21 is inserted into the groove 20. The silicone ring 21 surrounds the opening of the vent 16, and the sealing plate 23 is in contact with the silicone ring 21. The vent 8, the vent 16, and the vent chamber 15 are air intake holes. When the user inhales, air enters the inside of the e-cigarette from these three holes to achieve the inhalation process.

[0024] When the sealing plate 23 moves upward, it can compress the silicone ring 21 and seal the vent 16; When the electronic cigarette is not in use, in order to prevent dust from entering the air intake holes (vent 8, vent 16 and vent 15), the user can move the sealing plate 23 upward by pressing the sealing button 24, and then the sealing plate 23 will squeeze the silicone ring 21 to achieve the sealing function, thereby preventing dust and impurities from entering and causing the air intake holes to be blocked, affecting the use and improving the practicality.

[0025] Components not described in detail in this article are existing technologies.

[0026] The working principle and usage process of this utility model are as follows: During installation, the limiting blocks 17 are aligned with the longitudinal sliding grooves 11, and the cartridge body 5 is inserted into the installation port 10. When fully inserted, the limiting blocks 17 reach the end of the longitudinal sliding grooves 11. The cartridge body 5 is then rotated clockwise, and the limiting blocks 17 slide into the transverse sliding grooves 12. When the limiting blocks 17 slide to their end, the user will notice the attraction between the positive magnetic block 14 and the negative magnetic block 19, indicating that the installation is complete. At the same time, the corresponding conductive contact copper sheet 13 and conductive copper sheet 18 are connected. Through the limiting effect of the limiting blocks 17 and the transverse sliding grooves 12, the cartridge body 5 is stably installed, reducing the risk of falling off. Furthermore, the attraction between the positive magnetic block 14 and the negative magnetic block 19 also reduces the probability of the cartridge body 5 rotating in the opposite direction, further improving installation stability and practicality.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
