[0035] Please refer to Figures 1-8 , an embodiment of the present utility model discloses a dual-channel electronic atomization device.

[0036] As Figures 1-2As shown in the figure, the dual-channel electronic atomization device includes a housing 7, a mouthpiece 1, a liquid storage and atomization structure 2, and a power supply component 3. During assembly, the mouthpiece 1 is snap-fitted onto the liquid storage and atomization structure 2, so that the mouthpiece 1 and the liquid storage and atomization structure 2 form an integral structure. The power supply component 3 is inserted into the interior of the housing from the bottom of the housing, and the bottom of the housing 7 is pressed against the convex edge of the power supply component 3. Then, the assembled mouthpiece 1 and the liquid storage and atomization structure 2 are inserted into the housing 7 from the top of the housing 7 until the liquid storage and atomization structure 2 is fixed to the power supply component 3. At this time, the convex edge of the mouthpiece 1 is pressed against the top of the housing 7, and the power supply component 3 and the mouthpiece 1 fix the housing 7, completing the assembly of the dual-channel electronic atomization device.

[0037] The mouthpiece 1 is provided with a first ventilation hole 101 and a second ventilation hole 102, enabling the dual-channel electronic atomization device to atomize different atomization liquids.

[0038] The liquid storage and atomization structure 2 is used to store the atomization liquid and atomize the atomization liquid. The mouthpiece 1 is detachably arranged on the liquid storage and atomization structure 2. The liquid storage and atomization structure 2 includes a first atomization component 21 for atomizing the atomization liquid, a first liquid storage component 22 for storing the liquid, a second atomization component 23 for atomizing the atomization liquid, a second liquid storage component for storing the liquid, and a first bracket 25 for supporting. The first bracket 25 includes a top plate, a partition plate, and a bottom plate. The partition plate is respectively vertically arranged on the top plate and the bottom plate, and the partition plate is located at the center of the bottom plate, so that the partition plate divides the first bracket 25 into two parts. The first atomization component 21 is provided with a first atomization airway 211 communicated with the first ventilation hole 101, enabling the atomization gas to pass through the first through hole to the outside of the dual-channel electronic atomization device. The first atomization component 21 is arranged in the first liquid storage component 22, that is, the first liquid storage component 22 surrounds the periphery of the first atomization component 21, so that the first liquid storage component 22 can provide the atomization liquid for the first atomization component 21 to atomize. The first liquid storage component 22 provided with the first atomization component 21 is arranged on one side of the first bracket 25. The second atomization component 23 is provided with a second atomization airway 231 communicated with the second ventilation hole 102, enabling the atomization gas to pass through the second through hole 224 to the outside of the dual-channel electronic atomization device. The second atomization component 23 is arranged in the second liquid storage component 24, that is, the second liquid storage component 24 surrounds the periphery of the second atomization component 23, so that the second liquid storage component 24 can provide the atomization liquid for the second atomization component 23 to atomize. The second liquid storage component 24 provided with the second atomization component 23 is arranged on the other side of the first bracket 25, so that the dual-channel electronic atomization device has two separate liquid storage components and atomization components. Furthermore, each liquid storage component and each atomization component can store and atomize a kind of atomization liquid separately, having a dual-atomization liquid atomization conversion. The atomization liquid can be wormwood liquid or herb functional liquid, enabling the dual-channel electronic atomization device 100 to have an atomization moxibustion function.

[0039] AsFigure 3 As shown in the figure, the power supply component 3 includes a charging board 31 and a second bracket 32. The charging board 31 is circular, square, oval or the like, preferably circular, and a first bump 311 is provided on the peripheral side of the charging board 31. A bayonet 321 adapted to the first bump 311 is provided at one end of the second bracket 32 away from the liquid storage atomization structure 2. The first bump 311 is snapped into the bayonet 321 to form a fixation. The charging board 31 and the second bracket 32 are fixed by a snap connection method, making the fixation method simpler, avoiding screwing to fix the charging board 31, and the operation is convenient and fast.

[0040] During installation, since the material of the second bracket 32 is plastic and has elasticity, first pull open the part of the second bracket 32 near the bayonet 321, and then snap the first bump 311 into the bayonet 321 correspondingly. After the first bump 311 is in place, release the part of the second bracket 32. This part of the second bracket 32 has a resilience due to its elasticity, and the resilience presses the first bump 311 tightly, thereby fixing the charging board 31.

[0041] The power supply component 3 is electrically connected to the first atomization component 21 or the second atomization component 23. When the power supply component 3 is electrically connected to the first atomization component 21, the first atomization component 21 works to atomize the atomization liquid in the first liquid storage component 22. The atomized gas flows through the first atomization airway 211 to the first ventilation hole 101 and comes out from the first ventilation hole 101, and the second atomization component 23 does not work; when the power supply component 3 is electrically connected to the second atomization component 23, the second atomization component 23 works to atomize the atomization liquid in the second liquid storage component 24. The atomized gas flows through the second atomization airway 231 to the second ventilation hole 102 and comes out from the second ventilation hole 102, and the first atomization component 21 does not work; therefore, when the user wants to replace the atomization with different atomization liquids, the nozzle 1 needs to be rotated so that the corresponding atomization component is electrically connected to the power supply component 3.

[0042] As Figures 3-5As shown in the figure, specifically, a first groove 253 is provided at the bottom of the first bracket 25, and the first magnet 4 is fixed in the first groove 253. A second groove 328 corresponding to the first groove 253 is provided at the top of the second bracket 32, and the second magnet 5 magnetically attracted to the first magnet 4 is fixed in the second groove 328. The second bracket 32 and the first bracket 25 are fixedly connected and positioned by magnetic attraction, so that the second bracket 32 can be detachably arranged on the first bracket 25. When it is necessary to atomize different atomizing liquids, only need to pull the nozzle 1 slightly away from the outer housing 7 to separate the liquid storage atomizing structure 2 and the power supply component 3. After rotation, then push the nozzle 1 towards the outer housing 7 until it is magnetically fixedly connected to the power supply component 3, so that the positions of the first atomizing component 21 and the second atomizing component 23 are changed. The replaced atomizing component is electrically connected to the power supply component 3, and the atomizing component atomizes the atomizing liquid in the liquid storage component, thereby enabling different atomizing liquids to be atomized. The dual-channel electronic atomizing device can easily replace different atomizing liquids, and the fixing method is simple and convenient to operate by magnetic attraction.

[0043] Further, an elastic conductive member 33 is provided at the top of the second bracket 32. The elastic conductive member 33 can be a spring ejector pin. A first electrode 34 and a second electrode 35 are respectively provided at the bottom of the first bracket 25 corresponding to the first atomizing component 21 and the second atomizing component 23, and both the first electrode 34 and the second electrode 35 are located on the same circumferential line. The elastic conductive member 33 is located directly below the circumferential line.

[0044] Exemplarily, the first electrode 34 is electrically connected to the elastic conductive member 33. When it is desired to atomize different atomizing liquids, pull the nozzle 1 away from the outer housing 7, so that the second magnet 5 on the liquid storage atomizing structure 2 is separated from the first magnet 4 on the power supply component 3, and then rotate the nozzle 1. Since the nozzle 1 is integrally connected to the liquid storage atomizing structure 2, the rotation of the nozzle 1 drives the liquid storage atomizing structure 2 to rotate, so that the positions of the first electrode 34 and the second electrode 35 are interchanged. Then push the nozzle 1 towards the side close to the outer housing 7, so that the first magnet 4 and the second magnet 5 are magnetically attracted to each other. At this time, the second electrode 35 is electrically connected to the elastic conductive member 33, and the second atomizing component 23 starts to atomize. Only by pulling, rotating and pushing once can the atomizing liquid be changed, and the operation is simple and fast.

[0045] Such as Figure 6As shown, further, the second bracket 32 includes a first end plate 322, an arc connecting plate 323, and a second end plate 324. The first end plate 322 and the second end plate 324 can be circular, square, oval, etc., preferably circular. The two ends of the arc connecting plate 323 are respectively connected to the first end plate 322 and the second end plate 324, and the first end plate 322 and the second end plate 324 are arranged in parallel. The arc connecting plate 323 is respectively perpendicular to the first end plate 322 and the second end plate 324. The arcs of the arc connecting plate 323 are all adapted to the circular arcs of the first end plate 322 and the second end plate 324, that is, the convex surface of the arc connecting plate 323 is flush with the outer peripheral sides of the first end plate 322 and the second end plate 324. The power supply assembly 3 further includes a battery 37 and a microphone switch 36. The battery 37 is arranged on the second bracket 32 and is located on one side of the concave surface of the arc connecting plate 323. The battery 37 is located below the elastic conductive member 33, and the battery 37 is electrically connected to the elastic conductive member 33. A third through hole 327 is provided at the position of the arc connecting plate 323 corresponding to the charging plate 31. One end of the microphone switch 36 is electrically connected to the charging plate 31, and the other end of the microphone switch 36 passes through the third through hole 327 and is arranged on the convex surface of the arc plate, and is arranged close to one end of the liquid storage atomization structure 2. The microphone switch 36 and the first air inlet hole 325 and the second air inlet hole 326 are located on opposite sides of the arc connecting plate 323, so that the atomization air passage and the microphone switch 36 are isolated, and further the microphone switch 36 can not only sense the change of the air flow velocity, but also be isolated from the condensate or leakage generated by the energized atomization of the first atomization channel or the second atomization channel, avoiding the failure or damage of the microphone switch 36 caused by the condensate or leakage, and making the dual-channel electronic atomization device have a long service life.

[0046] The second end plate 324 on the second bracket 32 is provided with a first air inlet hole 325, and the first end plate 322 is provided with a second air inlet hole 326. The first air inlet hole 325, the second air inlet hole 326, the first atomization air passage 211, and the first ventilation hole 101 are communicated to form an air inlet passage, or the first air inlet hole 325, the second air inlet hole 326, the second atomization air passage 231, and the second ventilation hole 102 are communicated to form another air inlet passage.

[0047] During use, when the user sucks on the mouthpiece 1, since the intake passage is unobstructed, the pressure inside the intake passage becomes lower than the external pressure when the user sucks, causing air to flow in through the first intake holes 325 of the second end plate 324. Due to the gap between the battery 37 and the second bracket 32, the air flows through the gap to the second intake holes 326 on the first end plate 322. At the same time, the microphone switch 36 provided on the second bracket 32 senses the change in air flow velocity and then controls the power supply of the battery 37. The electricity is transmitted to the first electrode 34 or the second electrode 35 through the elastic conductive member 33, and the first atomization assembly 21 or the second atomization assembly 23 starts to heat and atomize. The atomized gas is diffused to the outside through the first atomization airway 211 and the first ventilation hole 101, or the atomized gas is diffused to the outside through the second atomization airway 231 and the second ventilation hole 102.

[0048] As Figure 7 shown, further, the first atomization assembly 21 and the second atomization assembly 23 have the same structure. The first atomization assembly 21 includes a heating wire, a liquid-conducting non-woven fabric 212, a metal housing 213, and a cavity tube 214. The liquid-conducting non-woven fabric 212 is provided with fourth ventilation holes. The liquid-conducting non-woven fabric 212 is arranged inside the metal housing 213. The heating wire is attached to the inner side wall of the metal housing 213 and is located between the metal housing 213 and the liquid-conducting non-woven fabric 212. When the heating wire works, the atomization liquid on the liquid-conducting non-woven fabric 212 is atomized. The metal housing 213 increases the heating area of the liquid-conducting non-woven fabric 212 and improves the working efficiency. One end of the cavity tube 214 is inserted into one end of the metal housing 213, and the inner cavity of the cavity tube 214 is respectively communicated with the first ventilation hole 101 and the fourth ventilation hole, so that the atomized gas flows through the fourth through hole and the inner cavity of the cavity tube 214 to the first ventilation hole 101.

[0049] As Figure 7 shown, further, the first liquid storage assembly 22 and the second liquid storage assembly 24 have the same structure. The first liquid storage structure includes a liquid storage cotton 221 and a liquid chamber 222. The first atomization assembly 21 is embedded in the liquid storage cotton 221. The metal housing 213 has a hollow part, and the liquid-conducting non-woven fabric 212 is located at the hollow part, so that the liquid-conducting non-woven fabric 212 contacts the liquid storage cotton 221, enabling the atomization liquid on the liquid storage cotton 221 to be guided to the liquid-conducting non-woven fabric. The liquid storage cotton 221 is arranged in the liquid chamber 222. Two liquid injection holes are provided at the top of the liquid chamber 222. During production, the atomization liquid is respectively injected onto the liquid storage cotton 221 through the two liquid injection holes 225 to achieve double-needle liquid injection and make the atomization liquid on the oil storage surface uniform, avoiding the situation of more on one side and less on the other side. The liquid chamber 222 prevents the atomization liquid on the liquid storage cotton 221 from leaking.

[0050] As Figure 7As shown, further, the first liquid storage component 22 further includes a liquid storage base 223, the liquid storage base 223 is inserted into the bottom of the liquid storage chamber 222, a second through hole 224 communicating with the first atomization airway 211 is provided at the bottom of the liquid storage chamber 222, and the second through hole 224 communicates with the second air inlet hole 326. In order to increase the sealing performance of the liquid storage chamber 222, a sealing silicone pad is sleeved on the liquid storage base 223, and the sealing silicone pad closely fits the inner side wall of the liquid storage chamber 222 to prevent the atomization liquid from leaking.

[0051] Further, the assembled first atomization component 21 and the first oil storage component are defined as the first liquid cartridge, and the assembled second atomization component 23 and the second oil storage component are defined as the second liquid cartridge. The nozzle 1 and the liquid storage and atomization structure 2 can be detachably arranged by means of a buckle. Second bumps 251 and a first limiting groove 252 are spaced around the circumference of the top of the first bracket 25. The nozzle 1 is provided with a second limiting groove 103 corresponding to the second bump 251, and the nozzle 1 is provided with a limiting post 104 corresponding to the first limiting groove 252. The nozzle 1 is sleeved on the first bracket 25 and rotated so that the second bump 251 is snapped into the first limiting groove 252, and the limiting post 104 is snapped into the second limiting groove 103, so that the nozzle 1 and the liquid storage and atomization structure 2 are assembled into one body, which is convenient for replacing different atomization liquids during use. At the same time, the detachable design enables the user to arbitrarily replace the first atomization liquid chamber or the second atomization liquid chamber according to their favorite atomization liquid.

[0052] Further, a fixing groove (not shown in the figure) is provided at the top of the first bracket 25. The dual-channel electronic atomization device further includes a sealing member 6.
