Description

Technical Field

[0001] The embodiments disclosed in this application relate to the field of electronic atomization technology, and in particular to electronic cigarettes. Background Art

[0002] E-cigarettes are vaporized products that heat a liquid matrix and atomize it into an aerosol for the user to inhale. To enrich the flavors of e-cigarettes, existing e-cigarettes are typically designed with two independent oil storage chambers filled with different flavors of e-liquid.

[0030] See also Figures 1 to 3The electronic cigarette provided in this embodiment will now be described. The electronic cigarette 100 in this embodiment includes a housing 1, an atomization module 2, a battery 3, and a bottom cover 4. One end of the housing 1 has an air outlet channel 11, and the other end of the housing 1 has an opening. The atomization module 2 and the battery 3 are separately assembled into the housing 1, and the bottom cover 4 seals the opening. The bottom cover 4 is provided with an air inlet 41. The atomization module 2 includes a liquid storage chamber 21, an atomization channel 22, and a heating assembly. The liquid storage chamber 21 is connected to the atomization channel 22. The heating assembly is disposed within the atomization channel 22 and is electrically connected to the battery 3. The liquid storage chamber 21 stores at least two different atomization substrates. Here, the two ends of the atomizing channel 22 are respectively connected to the air inlet 41 and the air outlet channel 11. The air inlet 41, the atomizing channel 22 and the air outlet channel 11 form an air circuit. The heating component is fixed to the inner wall of the atomizing channel 22. The atomizing channel 22 is connected to the liquid storage chamber 21. The atomized matrix stored in the liquid storage chamber 21 can flow to the heating component, and the heating component heats the atomized matrix to produce smoke for the user to inhale. At least two atomizing matrices are stored in the liquid storage chamber 21, and a liquid partition 26 is provided between the two atomizing matrices. A set of heating components is configured in the atomizing channel 22. The heating component can heat the two atomizing matrices at the same time to produce smoke. The two smokes can be fully integrated in the atomizing channel 22, enriching the taste of the smoke, thereby improving the use effect of the electronic cigarette 100.

[0031] The electronic cigarette 100 provided in this application is filled with two atomizing matrices: tobacco oil and cooling agent, wherein the cooling agent is located below the tobacco oil. The heating component is disposed in the atomizing channel 22 and is connected to the liquid storage chamber 21. The heating component can simultaneously heat the tobacco oil and cooling agent to produce two different flavors of smoke. Under the action of the suction force, the smoke formed by the cooling agent moves from the bottom section of the atomizing channel 22 toward the air outlet channel 11 to mix with the smoke generated by the tobacco oil. Due to the long diameter of the atomizing channel 22, the two atomized flavors of smoke can be fully mixed, enriching the taste of the smoke and improving the user experience. Of course, in some other embodiments, the liquid storage chamber 21 can also store three or more different types of atomizing matrices as needed.

[0032] In order to reduce the mixing of the two atomized matrices or the dilution of the cooling agent by the e-liquid, a liquid partition 26 is provided between the cooling agent and the e-liquid. Specifically, from top to bottom (along the opposite direction of the gas flow, that is, from the air outlet channel 11 to the air inlet 41), the liquid storage chamber 21 is provided with a first liquid storage cotton 27 and a second liquid storage cotton 28, and a liquid partition 26 is provided between the first liquid storage cotton 27 and the second liquid storage cotton 28. For example, an oil separation membrane is provided at the contact surface of the first liquid storage cotton 27 and the second liquid storage cotton 28. The first liquid storage cotton 27 stores the e-liquid, and the second liquid storage cotton 28 stores the cooling agent. The liquid storage cotton has a good oil-locking ability, which reduces the fluidity of the liquid, and an oil separation membrane is provided between the two liquid storage cottons. The oil separation membrane can prevent the e-liquid from penetrating into the cooling agent, thereby reducing the risk of confusion between the two atomized matrices.

[0033] Of course, in another embodiment, the electronic cigarette 100 further includes a liquid partition 26 installed in the liquid storage chamber 21. The liquid partition 26 is arranged transversely within the liquid storage chamber 21 perpendicular to the central tube 24. The liquid partition 26 divides the liquid storage chamber 21 into a first liquid storage chamber 211 and a second liquid storage chamber 212, which are arranged vertically. The first liquid storage chamber 211 is located above the second liquid storage chamber 212. It can be understood that the liquid partition divides the liquid storage chamber 21 into two independent chambers, each of which stores a different type of atomized matrix. The two atomized matrices share a common atomizing assembly, and the smoke generated by the heated atomized matrix can be fully mixed in the atomization channel 22, enriching the flavor of the smoke.

[0034] In one possible embodiment, please also refer to Figure 2 and Figure 3 , the heating assembly includes a central tube 24, a liquid guide 23 and a heating element 25. The central hole of the central tube 24 is configured to form an atomization channel 22. The liquid guide 23 is the same or substantially the same shape as the central tube 24. The liquid guide 23 is fixed in the central tube 24. The heating element 25 is wound into a C shape and fits into the inner side wall of the liquid guide 23. Among them, a plurality of liquid inlet holes 241 are provided on the side walls of the central tube 24 corresponding to the two atomization matrices. The plurality of liquid inlet holes 241 are distributed around the central tube 24, and any two liquid inlet holes 241 are not connected to avoid the two atomization matrices from confusing each other without being heated, thereby affecting the atomization effect. Here, only one set of heating assemblies is used to realize the heating and atomization of the two atomization matrices. Compared with the left and right side-by-side double-core double-cavity, at least one set of heating assemblies is reduced, which saves costs and is convenient for assembly. The aerosol formed by the atomization matrix can be fully integrated in the same atomization channel 22 to ensure the taste of the smoke.

[0035] Specifically, notches 242 are provided at each end of the central tube 24 along the middle of the central tube 24. The two notches 242 are not connected. The liquid guide 23 includes a first liquid guide 231 and a second liquid guide 232. The first liquid guide 231 and the second liquid guide 232 are spaced apart along the height of the central tube 24. A portion of the first liquid guide 231 extends into one of the atomizing matrices through one of the notches 242, and a portion of the second liquid guide 232 extends into the other atomizing matrices through the other notch 242. During assembly, the first liquid guide 231 and the second liquid guide 232 are respectively inserted into the central tube 24 along the two notches 242, and one end of each liquid guide 23 extends into the liquid storage chamber 21 to contact the corresponding atomizing matrices. Since the two liquid guides 23 are not in contact, the atomized matrices transmitted through the liquid guides 23 will not mix, thereby preventing the smoke oil from covering the cooling agent and diluting the atomization effect of the subsequent cooling agent, thereby resulting in poor quality of the smoke. Preferably, an isolation member (not shown) may be provided between the two liquid-conducting bodies 23 , and the isolation member may be a multi-layer nano-breathable oil-isolating membrane.

[0036] like Figure 3 As shown, the heating element 25 includes a first heating mesh 251 and a second heating mesh 252. The first heating mesh 251 is attached to the inner wall of the first liquid-conducting body 231, and the second heating mesh 252 is attached to the inner wall of the second liquid-conducting body 232. The first heating mesh 251 and the second heating mesh 252 are respectively connected to the battery 3 via pins 253. Heating meshes are provided between the two liquid-conducting bodies 23, effectively dividing a larger heating mesh into two smaller ones. This facilitates the processing and manufacture of the heating element 25, reduces the probability of deformation of the heating mesh, and prevents the middle section of the heating mesh not wrapped with the liquid-conducting body 23 from burning due to insufficient liquid supply. Heating meshes are provided on both sides of the two liquid-conducting bodies 23, enabling the simultaneous generation of cooling agent and e-liquid smoke. As the cooling agent vapor moves from the lower section of the central tube 24 toward the air outlet channel 11 under the action of suction force, it fully merges with the aerosol generated by the e-liquid, ensuring a rich and flavorful smoke.

[0037] Furthermore, the pins 253 of the first heating mesh 251 and the pins 253 of the second heating mesh 252 extend along both ends of the central tube 24 and are connected to the battery 3. Flywheels (not shown) are inserted at both ends of the central tube 24 located at the heating element 25. The flywheels secure the pins 253, reducing the probability of deformation of the heating mesh due to pulling on the pins 253 during subsequent assembly and welding. Leading the pins 253 of the two heating meshes from both ends of the central tube 24 facilitates wiring and reduces the problem of short circuits caused by the pins 253 crossing each other.

[0038] Furthermore, the first heating mesh 251 includes two heating cells 254, a common pin, and two independent pins. The two heating cells 254 are spaced apart along the height of the central tube 24. One end of each heating cell 254 is connected to the common pin, and the other end of each heating cell 254, away from the common pin, is welded to an independent pin. The two independent pins are spaced apart. In other words, the first heating mesh 251 has two heating cells 254 connected in parallel. These two heating cells 254 can simultaneously heat the atomized e-liquid, producing a large amount of vapor, thus satisfying the user's desire for a large vapor volume.

[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
