Description

Technical Field

[0001] This application belongs to the field of electronic atomization technology, and more specifically, relates to an electronic atomization device. Background Technology

[0002] Electronic atomizing devices are battery-powered devices that heat liquid atomizing agent (commonly known as "e-liquid") stored in a reservoir, transforming it into an aerosol that can be inhaled by the user. Since their introduction, they have gained widespread market acceptance due to their potential harm reduction characteristics compared to traditional tobacco products and their ease of use. However, as technology continues to evolve, existing mainstream products are gradually revealing their inherent limitations in meeting the increasingly personalized needs of users.

[0003] Specifically, most mainstream electronic atomizing devices currently only have one independent reservoir. This reservoir is used to hold liquid atomizers with specific ingredients and flavors. As a result, from the moment the device is used until the atomizer in the reservoir is depleted, the flavor that the user can experience is entirely determined by the physicochemical properties of the single type of atomizer initially injected. This lack of freedom of choice and variation negatively impacts the user experience. Utility Model Content

[0026] The beneficial effect of the electronic atomizing device 10 provided in this application is that, compared with the prior art, each cartridge component 300 in the electronic atomizing device 10 of this application is used to fill liquid atomizing agents of different components.

This can effectively improve the freedom of choice and change of the device's atomizing experience and improve the user experience.

[0027] Please refer to the following: Figure 3 and Figure 4In each cartridge assembly 300, the first connecting end 303 is a slot structure for forming a plug-in fit, and the second connecting end 304 is a plug structure suitable for forming a plug-in fit.

[0028] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5 In the corresponding mouthpiece assembly 100, the mouthpiece connecting end 103 is a plug-in structure suitable for forming a plug-in fit, and in the battery assembly 200, the battery connecting end 203 is a slot structure suitable for forming a plug-in fit.

[0029] Please refer to the following: Figure 3 and Figure 4 The inner wall of the first connecting end 303 is provided with a cartridge locking groove, and the outer wall of the second connecting end 304 is provided with a cartridge locking protrusion. The cartridge locking protrusion of any cartridge assembly 300 is suitable for locking into the cartridge locking groove of any other cartridge assembly 300. When inserting, as the insertion structure of the second connecting end 304 of any cartridge assembly 300 is inserted into the slot structure of the first connecting end 303 of another cartridge assembly 300, the cartridge locking protrusion will gradually slide into the guide surface of the cartridge locking groove and finally lock into the groove, realizing the fixed connection between one cartridge assembly 300 and another cartridge assembly 300. This achieves the simultaneous completion of mechanical locking and air circuit sealing, ensuring a stable connection and easy disassembly, preventing accidental detachment during use, and ensuring the continuity and sealing of the airflow channel.

[0030] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5The outer wall of the corresponding mouthpiece connecting end 103 is provided with a mouthpiece locking protrusion, and the inner wall of the battery connecting end 203 is provided with a battery locking groove. The mouthpiece locking protrusion is suitable for locking into the cartridge locking groove of any cartridge assembly 300. The cartridge locking protrusion of any cartridge assembly 300 is also suitable for locking into the battery locking groove. When connecting, as the insertion structure of the mouthpiece connecting end 103 is inserted into the slot structure of the first connecting end 303 of the cartridge assembly 300, the mouthpiece locking protrusion will gradually slide into the guide surface of the cartridge locking groove and finally lock into the groove, realizing the mouthpiece locking mechanism. The fixed connection between component 100 and cartridge component 300 is achieved by the following process: when the insert structure of the second connecting end 304 of cartridge component 300 is inserted into the slot structure of the battery connecting end 203, the cartridge locking protrusion of cartridge component 300 will gradually slide into the guide surface of the battery locking groove and finally lock into the groove, thereby achieving a fixed connection between cartridge component 300 and battery component 200. This achieves simultaneous completion of mechanical locking and air passage sealing, ensuring a stable connection and easy disassembly, preventing accidental detachment during use, and ensuring the continuity and sealing of the airflow channel.

[0031] In some other embodiments, the inner wall of the corresponding mouthpiece connecting end 103 is provided with a mouthpiece locking groove (not shown in the figure), and the inner wall of the battery connecting end 213 is provided with a battery locking protrusion (not shown in the figure). The battery locking protrusion is suitable for locking into the mouthpiece locking groove of any tobacco cartridge assembly 300. The mouthpiece locking protrusion of any tobacco cartridge assembly 300 is also suitable for locking into the mouthpiece locking groove. When the insert structure of the second connecting end 304 of the tobacco cartridge assembly 300 is inserted into the mouthpiece connecting end 103, the mouthpiece locking protrusion of the tobacco cartridge assembly 300 will gradually slide into the mouthpiece locking groove through the guide surface and finally lock into the groove, thereby realizing the fixed connection between the tobacco cartridge assembly 300 and the mouthpiece assembly 100 and forming a stable mechanical lock. Similarly, when the insert structure of the battery connection end 203 is inserted into the first connection end 303 of any cartridge assembly 300, the battery locking protrusion will gradually slide into the guide surface of the cartridge locking groove of the cartridge assembly 300 and finally lock into the groove, thereby achieving a fixed connection between the battery assembly 200 and the cartridge assembly 300 and forming a stable mechanical lock.

[0032] Please see Figure 6The cartridge assembly 300 includes a cartridge shell body 310, a first cartridge cover 330, a second cartridge cover 340, and an atomizing unit 350. The first cartridge cover 330 and the second cartridge cover 340 are respectively disposed on opposite ends of the cartridge shell body 310 and cooperate with the cartridge shell body 310 to form an oil-containing cavity. The cartridge shell body 310 and the first cartridge cover 330 can be integrally injection molded, together forming the main chamber of the oil-containing cavity. The first cartridge cover 330 has a first connecting end 303 on the side facing away from the oil-containing cavity, and the second cartridge cover 340 has a second connecting end 304 on the side facing away from the oil-containing cavity. The atomizing unit 350 is disposed in the oil-containing cavity, and an oil-containing cotton is disposed inside the oil-containing cavity. The oil-containing cotton is used to saturate and store the liquid atomizing agent and continuously supply oil to the atomizing unit 350. The first cartridge cover 330 has a first air passage interface 301 that connects to the atomizing unit 350, and the second cartridge cover 340 has a second air passage interface 302 that connects to the atomizing unit 350. The first connecting electrode 360 ​​is inserted into the first cartridge cover 330 and extends into the oil storage cavity to electrically connect to the atomizing unit 350. The second connecting electrode 370 is inserted into the second cartridge cover 340 and extends into the oil storage cavity to electrically connect to the atomizing unit 350. The first connecting electrode 360 ​​and the second connecting electrode 370 are electrically connected through the atomizing unit 350.

[0033] It should be noted that the outer surface of the cartridge shell 310 can be decorated with different patterns, colors or textures, which can not only enhance the product's aesthetics and recognizability, but more importantly, these differentiated appearance features can intuitively and quickly distinguish the composition or flavor type of the liquid atomizing agent stored in different cartridge components 300, thereby enabling accurate and efficient flavor selection and combination during assembly or replacement, and improving the operational convenience and user experience in multi-cartridge series usage scenarios.

[0034] In this embodiment, the first cartridge cover 330 has a cartridge engaging groove on the inner wall of the first connecting end 303. The cartridge engaging groove includes a cartridge guide groove extending axially along the first connecting end 303 and a cartridge limiting groove extending circumferentially along the first connecting end 303. The axial direction of the first connecting end 303 is the insertion movement direction when the mouthpiece connecting end 103 is inserted into the first connecting end 303, and the circumferential direction of the first connecting end 303 is the rotation direction of the mouthpiece connecting end 103 relative to the first connecting end 303 after it is inserted into the first connecting end 303. One end of the cartridge guide groove passes through the end of the first cartridge cover 330 facing away from the cartridge shell body 310 to form an insertion entrance, and the other end connects to the cartridge limiting groove. The second cartridge cover 340 has a cartridge engaging protrusion on the outer wall of the second connecting end 304.

[0035] Please see Figure 7The atomizing unit 350 includes an atomizing tube body 351, an oil-retaining cotton body 352, a first sealing silicone 353, and a second sealing silicone 356. The atomizing tube body 351 is coaxially disposed in the oil-retaining cavity, and the oil-retaining cotton body 352 is arranged around the outside of the atomizing tube body 351. The first sealing silicone 353 is disposed between the first cartridge cover 330 and the oil-retaining cotton body 352, and has a first clearance through hole that connects the first air passage interface 301 and the corresponding end of the atomizing tube body 351 respectively. The second sealing silicone 356 is disposed between the second cartridge cover 340 and the oil-retaining cotton body 352, and has a second air passage that connects the second air passage interface 302 and the corresponding end of the atomizing tube body 351 respectively. The bypass through-holes allow the first connecting electrode 360 ​​and the second connecting electrode 370 to be electrically connected to the atomizing tube 351, and connected through the corresponding circuit of the atomizing tube 351. The first sealing silicone 353 and the second sealing silicone 356 can achieve axial bidirectional sealing, forming a tight elastic contact between the oil storage cotton body 352 and the end caps, which can prevent the liquid atomizing agent in the oil storage cavity from leaking from the end interfaces. Secondly, the bypass through-holes on the sealing silicone can be aligned and connected to the external air passage interface and the internal atomizing tube 351, ensuring smooth and directional flow of the intake airflow, and providing the atomizing unit 350 with a reliable seal, stable structure and smooth airflow working environment.

[0036] In other embodiments, the atomizing unit 350 may further include a third sealing silicone 359. The third sealing silicone 359 is sleeved on the outside of the oil-retaining cotton body 352, and its outer periphery is elastically and tightly fitted to the inner wall of the cartridge shell body 310. Its two end faces elastically abut against the opposing sides of the first sealing silicone 353 and the second sealing silicone 356, respectively. Thus, the first sealing silicone 353, the second sealing silicone 356, and the third sealing silicone 359 together constitute a complete sealing system, achieving all-round coverage and sealing of the oil-retaining cotton body 352. This ensures that the liquid atomizing agent can be contained within the flexible cavity made of silicone components in any usage posture, preventing leakage to the outside. At the same time, it can also avoid direct contact between the liquid atomizing agent and the hard plastic shell, helping to maintain the purity of the e-liquid flavor.

[0037] In this embodiment, the atomizing unit 350 further includes a first annular cotton body 354, a first annular silicone 355, a second annular cotton body 357, and a second annular silicone 358. The first sealing silicone 353 has a first annular groove surrounding the edge of the first clearance hole on the side facing the first cartridge cover 330. The first annular cotton body 354 is adapted to be disposed in the first annular groove and surrounds the first air passage interface 301. The first annular silicone 355 is surrounded on the inner wall of the first air passage interface 301. The second sealing silicone 356 faces the second cartridge cover 34. One side of the 0 is provided with a second annular groove surrounding the edge of the second clearance through hole. The second annular cotton body 357 is adapted to be disposed in the second annular groove and surrounds the second air passage interface 302. The second annular silicone 358 is surrounded on the inner wall of the second air passage interface 302. By setting the annular cotton body at the air passage interface, the condensate generated during the atomization process and that may be formed during the intermittent use can be actively captured, absorbed and temporarily stored, preventing the condensate from being directly inhaled into the user's mouth or accumulating at the interface and affecting the electrical reliability of the connection, thereby improving the user experience.

[0038] Please see Figure 2 The mouthpiece assembly 100 includes a mouthpiece housing 110. One end of the mouthpiece housing 110 has a mouthpiece connecting end 103. The mouthpiece housing 110 has an air intake channel inside. One end of the air intake channel adjacent to the mouthpiece connecting end has a mouthpiece air passage interface 101. The other end of the air intake channel penetrates the end surface of the mouthpiece housing 110 away from the mouthpiece connecting end 103, forming an air intake hole for air intake. The mouthpiece connecting end 103 is a plug structure, and the mouthpiece housing 110 has a mouthpiece locking protrusion on the outer wall of the mouthpiece connecting end 103.

[0039] In some other embodiments, the mouthpiece connection end 103 is a slot structure, and the corresponding mouthpiece housing 110 has a mouthpiece snap-fit ​​groove on the inner wall of the mouthpiece connection end 103. The mouthpiece snap-fit ​​groove includes a mouthpiece guide groove extending axially along the mouthpiece connection end 103 and a mouthpiece limiting groove extending circumferentially along the mouthpiece connection end 103. One end of the mouthpiece guide groove passes through the corresponding end of the mouthpiece housing 110, and the other end is connected to the mouthpiece limiting groove.

[0040] Please refer to the following: Figure 5 and Figure 8The battery assembly 200 includes a battery housing body 220, a first battery cover 230, a second battery cover 240, and battery cells (not shown). The first battery cover 230 and the second battery cover 240 are respectively installed on opposite ends of the battery housing body 220, and cooperate with the battery housing body 220 to form a battery cavity. The first battery cover 230 has a battery connection end 203 on the side facing away from the battery cavity. The battery cells are disposed in the battery cavity. The first battery cover 230 has a battery air passage interface 201. The battery housing body 220 has an airflow hole communicating with the outside to introduce external air. The battery assembly 200 also includes an air switch (not shown) disposed inside it. The air switch is electrically connected to the battery cells and the battery connection electrode 210, and is used to control the power supply of the battery cells to the outside based on airflow sensing. The battery connection electrode 210 is inserted into the first battery cover 230 and extends into the battery cavity to electrically connect the battery cells and the air switch.

[0041] In this embodiment, the battery connection end 203 is a slot structure, and the corresponding first battery cover 230 is provided with a battery snap-fit ​​groove on the inner wall of the battery connection end 203. The battery snap-fit ​​groove includes a battery guide groove extending axially along the battery connection end 203 and a battery limiting groove extending circumferentially along the battery connection end 203. One end of the battery guide groove passes through one end of the first battery cover 230 facing away from the battery outer shell body 220, and the other end is connected to the battery limiting groove.

[0042] In some other embodiments, the battery connection end 203 is a plug structure, and the corresponding first battery cover 230 has a battery snap-fit ​​protrusion on the outer wall of the battery connection end 203.

[0043] In this embodiment, the second battery cover 240 has a spare connection end 204 on the side facing away from the battery cavity. The second connection end 304 of any cartridge assembly 200 is also suitable for detachably connecting to the spare connection end 204. The corresponding spare connection end 204 is a slot structure for forming a plug-in fit. The inner wall of the spare connection end 204 is provided with a spare snap-fit ​​groove. The cartridge snap-fit ​​protrusion of any cartridge assembly 200 is also suitable for snapping into the spare snap-fit ​​groove. By adding a spare connection end 204 to the battery assembly 200, a cartridge assembly 300 that is temporarily not needed but is desired to be carried can be connected to the spare connection end 204 of the battery assembly. This combines the "idle storage" function with the device structure, allowing spare cartridges to be stored in the spare connection end 204. The "accessories" that used to be carried separately are now part of the device itself, avoiding the inconvenience of carrying them and the risk of loss. In addition, although the second air passage interface 302 on the cartridge assembly 300, which was originally used to connect to the downstream components, is physically open, it has been transformed into an independent and sealed oil storage chamber by internal sealing components in the aforementioned embodiment. The open air passage interface only serves as a potential air intake or airflow channel, while the liquid atomizer in the oil storage chamber is tightly sealed and will not leak from here. This ensures safety and cleanliness when carrying the device, thereby enabling the fulfillment of all scenarios from single flavor experience to complex flavor exploration, and mobile portability. It achieves a unity of functionality and convenience, greatly enhancing the practical value of the product and the user experience.

[0044] In some other embodiments, the second connecting end 304 of any cartridge assembly 300 is also adapted to be detachably connected to a spare connecting end 204, the corresponding spare connecting end 204 being a slot structure for forming a plug-in fit, the inner wall of the spare connecting end 204 being provided with a spare snap-fit ​​groove, and the cartridge snap-fit ​​protrusion of any cartridge assembly 300 being adapted to snap into the spare snap-fit ​​groove.

[0045] In one scenario, when the spare connection end 204 and the battery connection end 203 have the same structure, both are slot structures. In this configuration, to ensure consistency in the overall system connection logic, the mouthpiece connection end 103 is correspondingly configured as a pin structure, allowing for a perfect fit between the two ends of the cartridge assembly 300. In another scenario, when the spare connection end 204 and the battery connection end 203 have different structures, the battery connection end 203 is a slot structure, while the spare connection end 204 is a pin structure. In this case, the mouthpiece connection end 103 must be a slot structure to accept the pin of the first connection end 303 of the cartridge assembly 300. Finally, in yet another scenario, when the spare connection end 204 and the battery connection end 203 have different structures, the battery connection end 203 is a pin structure, while the spare connection end 204 is a slot structure. In this case, the mouthpiece connection end 103 must be a pin structure to insert into the slot of the first connection end 303 of the cartridge assembly 300. In another scenario, both the battery connection end 203 and the spare connection end 204 are plug-in structures. In this case, the mouthpiece connection end 103 needs to be a slot structure.

[0046] In summary, as long as the insertion end and slot end of the cartridge assembly 300 can effectively cooperate with the battery assembly 200 and the mouthpiece assembly 100 respectively, the specific structural forms of the battery connection end 203, the spare connection end 204 and the mouthpiece connection end 103 can be flexibly combined in various ways.

[0047] In this embodiment, the spare connection end 103 is a slot structure, and the corresponding second battery cover 240 is provided with a spare snap-fit ​​groove on the inner wall of the spare connection end 204. The battery snap-fit ​​groove includes a spare guide groove extending axially along the spare connection end 204 and a spare limiting groove extending circumferentially along the spare connection end 204. One end of the spare guide groove passes through one end of the second battery cover 240 facing away from the battery housing body 220, and the other end is connected to the spare limiting groove.

[0048] In some other embodiments, the spare connection end 204 is a plug structure, and the corresponding second battery cover 240 is provided with a spare snap-fit ​​protrusion on the outer wall of the spare connection end 204.

[0049] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
