Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, and in particular to electronic atomization devices. Background Technology

[0002] E-cigarettes are a common type of electronic atomization device, mainly composed of a battery, a heating element, and a container filled with e-liquid. They have a similar appearance, smoking experience, and taste to traditional cigarettes, but do not produce tar, carbon monoxide, ash, open flame, or harmful substances like lead and mercury. The e-liquid typically contains nicotine, propylene glycol, vegetable glycerin, and other chemicals. Powered by the battery, the heating element heats up, causing the e-liquid to evaporate and form vapor. Some smokers use them as an alternative to traditional cigarettes, satisfying their smoking habits and needs while reducing health risks. Furthermore, e-cigarettes can be customized with different flavored cartridges, such as tobacco, mint, and fruit. Compared to traditional cigarettes, e-cigarettes have several advantages: they produce relatively less smoke and odor, having a smaller impact on those around them; they do not contain tar or carbon monoxide, thus reducing harm to the human body to some extent; and they offer a rich variety of flavors, including traditional tobacco, mint, and fruit, to satisfy different preferences.

[0003] A search revealed Chinese Patent Publication No. CN218185232U, which discloses an electronic atomizing device and its power supply assembly. The power supply assembly includes a shell body, a power supply component, and an end cap assembly. The shell body has an open-end accommodating cavity, in which the power supply component is installed. The end cap assembly includes a base, an electrode plate, and a sliding cover. The electrode plate is fixed on the base. The base is rotatably connected to the shell body to open or close the opening of the accommodating cavity. The sliding cover is slidably connected to the base, and when the sliding cover slides relative to the base, it is snapped into the shell body. In this utility model's technical solution, the end cap assembly includes a slidingly connected base and a sliding cover. The base drives the electrode sheet to rotate and close the opening, and then the sliding cover slides to snap together with the shell body. This avoids damage to the electrode sheet caused by the base's rotation and translation, reduces electrode sheet wear, avoids poor contact, and facilitates the normal operation of the power supply component of the electronic atomizing device. Although this device reduces electrode sheet wear, avoids poor contact, and facilitates the normal operation of the power supply component of the electronic atomizing device, it cannot solve the problem of unstable fixation and the need to use glue for fixation, making disassembly and replacement difficult.

[0047] Working principle: First, the power supply module 7 is placed inside the cylinder 12. At this time, the power supply module 7 drives the annular baffle 8 to move downward. Then, the cylindrical buckle 11 on the annular baffle 8 contacts the cylinder 12 and retracts inward. The cylindrical buckle 11 then compresses the spring 10 inside the circular groove 9, causing it to deform. Then, when the cylindrical buckle 11 contacts the circular groove 13 on the cylinder 12, the cylindrical buckle 11 springs back under the restoring force of the spring 10, locking the circular groove 13 on the cylinder 12. At this time, the power supply module 7... The entire assembly is fixed on the cylinder 12. Then, the power supply module 7 is inserted back onto the fixing block 3. At this time, the front baffle 4 on the fixing block 3 will block the power supply module 7, allowing it to move along the surface of the front baffle 4. Simultaneously, the cylindrical head 6 on the power supply module 7 will be inserted into the circular hole 5 of the fixing block 3. Because the fixing block 3 is fixed inside the cylinder 1, the power supply module 7 will be fixed inside the cylinder 1, thus achieving the function of fixing the power supply module 7 to the cylinder 1 through the fixing block 3, preventing abnormal power supply caused by poor contact.

[0048] First, place the battery 17 inside the side panel 201. Then, arrange the connecting plates 203 on the side of the battery 17. Align the second circular hole 204 on the connecting plate 203 with the first circular hole 202. Then, insert the connecting post 205. The second connecting plate 206, along with the connecting post 205, is inserted into the second circular hole 204 of the connecting plate 203 and the first circular hole 202 of the power supply module 7, thus fixing the battery 17 to the power supply module 7. When disassembly is required, remove the second connecting plate 206 along with the connecting post 205, and then remove the battery 17 along with the connecting plate 203 from the side panel 201. This achieves the function of stably and firmly fixing the battery 17 to the power supply module 7, preventing it from moving or shifting.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
