Description

Technical Field

[0001] This utility model belongs to the technical field of atomization devices, specifically relating to an electronic atomization device. Background Technology

[0002] Atomizing devices are devices that heat stored atomizable substances to form an atomized state, such as electronic cigarettes, which heat e-liquid or other similar substances to form smoke for users to inhale.

[0003] As people's living standards improve, single-flavor electronic atomizing devices can no longer meet users' needs, so multi-flavor electronic atomizers have appeared on the market. For example, the multi-flavor electronic atomizer disclosed in Chinese Utility Model Patent No. CN219679760U includes a main body and a mouthpiece located at one end of the main body. The main body has multiple atomizing chambers arranged side by side and all extending through the end of the main body near the mouthpiece. The mouthpiece is rotatably connected to the main body and has a suction channel inside. By rotating relative to the main body, the mouthpiece allows the suction channel to selectively connect with one of the atomizing chambers.

[0004] For example, an electronic atomizer disclosed in Chinese invention patent application CN119184362A includes a mouthpiece structure and an atomizer body, with the mouthpiece structure rotatably connected to the atomizer body. Inside the atomizer body, a control module and a power supply are arranged sequentially along the central axis of the atomizer body. A first atomizing device and a second atomizing device are respectively arranged on both sides of the control module, and a first oil storage device and a second oil storage device are respectively arranged on both sides of the power supply. A first atomizing channel and a second atomizing channel are respectively arranged on the first atomizing device and the second atomizing device. When the connecting hole on the mouthpiece structure is connected to the first atomizing channel or the second atomizing channel, the first sealing structure seals the second atomizing channel or the first atomizing channel accordingly.

[0005] It can be seen that there are many types of multi-flavor electronic atomizers in the existing technology, which can meet users' needs for different flavors. However, since e-liquid is formed into an atomized state by heating, the atomized vapor will condense into e-liquid when it is cooled. This can easily lead to the condensed e-liquid adhering to the air outlet channel of the mouthpiece. Furthermore, since the mouthpiece is in direct contact with the mouth, it is easy for users to inhale it into their mouths, affecting the vaping experience. Utility Model Content

[0050] As shown in Figure 4 , Figure 5 and Figure 6 , the top cover 4 is provided with two guide holes 17 corresponding to the atomization channel 7. The guide hole 17 includes a constant diameter hole section 38 and a variable diameter hole section 39. The variable diameter hole section 39 is a tapered hole section with a diameter gradually increasing from top to bottom. The variable diameter hole section 39 is provided with a tapered guide surface 18. The top cover 4 and the two oil bottles 13 form installation cavities therebetween. The installation cavities are provided with oil suction members 8. As shown in Figure 7 , the oil suction member 8 is provided with an avoidance groove 9 for avoiding the second installation groove 40. The oil suction member 8 is also provided with a through hole 31 communicating with the atomization channel 7. Figure 9As shown, the variable-diameter hole section 39 is entirely deep into the through hole 31 of the oil absorption member 8, so that the maximum diameter of the variable-diameter hole section 39 is greater than the diameter of the atomization channel 7 and less than the diameter of the through hole 31, and the bottom of the variable-diameter hole section 39 is higher than the bottom of the oil absorption member 8. The variable-diameter hole section 39 is provided with a plurality of oil guide holes 10 which are circumferentially distributed around the axis of the guide hole 17. The guide surface 18 is used to guide the tobacco oil in the condensation state in the suction nozzle 2 to the through hole 31 to be absorbed by the oil absorption member 8. The setting of the constant-diameter hole section 38 prolongs the dripping time of the tobacco oil in the condensation state and reduces the possibility of the tobacco oil in the condensation state directly dripping into the atomization channel 7. In this embodiment, the oil absorption member 8 also uses oil absorption cotton, and of course, the oil absorption member 8 can also use oil absorption resin. In order to ensure sealing, sealing silica gel is arranged between the oil absorption member 8 and the top cover 4.

[0051] As shown in Figure 4 The top cover 4 is provided with a concave sealing groove 12 on the radially outer side of the guide hole 17, and the sealing groove 12 is provided with sealing silica gel for sealing the gap between the suction channel 3 and the guide hole 17. The depth of the sealing groove 12 is less than the depth of the constant-diameter hole section 38, so as to form a positioning step 11 on the side of the top cover 4 facing the oil bottle 13 for positioning the oil absorption member 8. After the top cover 4 is buckled with the oil bottle 13, the oil absorption member 8 is pressed downward to be stably fixed.

[0052] As shown in Figure 8 The suction nozzle 2 is provided with a sealing protrusion 43 at a position symmetrical to the suction channel 3, and the sealing protrusion 43 is used to shield and seal the guide hole 17 and the corresponding atomization channel 7. Regardless of the state, the suction channel 3 is in communication with one of the guide hole 17 and the atomization channel 7, and the sealing protrusion 43 shields and seals the other guide hole 17, that is, the sealing protrusion 43 shields and seals the other atomization channel 7.

[0053] The electronic atomization device of the utility model rotates the suction nozzle 2 relative to the atomization main body 1 to make the suction channel 3 selectively correspondingly communicate with one of the atomization channels 7, and the other atomization channels 7 are sealed by the sealing protrusion 43. When the temperature of the use environment of the electronic atomization device decreases, the tobacco oil in the atomization state will become condensate oil beads after being cooled, and adhere to the suction channel 3 of the suction nozzle 2; since the electronic atomization device is in a vertical state when a person sucks, if the suction channel 3 of the suction nozzle 2 adheres to the tobacco oil in the condensation state, the tobacco oil will fall into the guide hole 17, and flow to the oil absorption member 8 through the guide surface 18 on the guide hole 17 and the oil guide holes 10, and then be absorbed and removed by the oil absorption member 8, without affecting the suction taste.

[0054] Embodiment 2 of the electronic atomization device provided by the utility model:

[0055] The difference between the embodiment 1 and the embodiment 2 is mainly that:

[0056] In the embodiment 1, the guide hole 17 comprises an equal-diameter hole section 38 and a variable-diameter hole section 39.

[0057] In the embodiment, the guide hole 17 only comprises the variable-diameter hole section 39, which is a tapered section with gradually increasing diameter from top to bottom.

[0058] The embodiment 3 of the electronic atomization device provided by the utility model:

[0059] The difference between the embodiment 1 and the embodiment 3 mainly lies in that:

[0060] In the embodiment 1, the guide surface 18 is a tapered surface.

[0061] In the embodiment, the guide surface 18 is a wedge-shaped surface.

[0062] In the description of the present specification, the meaning of "a plurality of" is at least two, for example, two, three or more, etc., unless otherwise expressly specifically limited.

[0063] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
