[0031] Example 1

[0032] To address the technical deficiencies in related technologies, this embodiment provides an electronic cigarette. For example... Figures 1 to 3 As shown, the electronic cigarette of this embodiment includes an atomizing device 100, an e-liquid reservoir 200, and a power supply device 300. The atomizing device 100 has a mouthpiece 140 at its top and an atomizing chamber 130 formed within it. An atomizing core 131 is disposed within the atomizing chamber 130 and communicates with the mouthpiece 140. A first conductive contact 110 is provided on the first side 101 of the atomizing device 100, and is electrically connected to the atomizing core 131. A connecting channel 120 is provided at the bottom of the atomizing device 100, communicating with the atomizing chamber 130. The atomizing chamber 130 can store a small amount of e-liquid for atomization by the atomizing core 131. The user can inhale the aerosol generated by the atomizing core 131 through the mouthpiece 140.

[0033] The e-liquid reservoir 200 can hold a relatively large amount of e-liquid; for example, the capacity of the reservoir 200 can be set to five times that of the atomizing chamber 130. The top of the reservoir 200 has an inlet channel 201. The top of the reservoir 200 can be detachably connected to the bottom of the atomizing device 100 via splicing, magnetic attraction, or snap-fit, but is not limited to these methods. When the reservoir 200 is detachably connected to the atomizing device 100, the inlet channel 201 and the connecting channel 120 are interconnected.

[0034] After the oil storage bottle 200 is connected to the atomizing device 100, the e-liquid in the oil storage bottle 200 flows into the atomizing chamber 130 in sequence through the oil inlet channel 201 and the connecting channel 120 by tilting the device.

[0035] The power supply device 300 is used to supply power to the atomizing device 100, and a rechargeable battery cell is provided inside. The second side 301 of the power supply device 300 is provided with a second conductive contact 310, which is electrically connected to the battery cell.

[0036] In this embodiment, the first side 101 of the atomizing device 100 is detachably connected to the second side 301 of the power supply device 300, so that the first conductive contact 110 and the second conductive contact 310 are in contact, thereby allowing the atomizing core 131 to be electrically connected to the battery cell through the first conductive contact 110 and the second conductive contact 310 in sequence, so that the atomizing core 131 can atomize the e-liquid flowing into the atomizing chamber 130.

[0037] In the electronic cigarette of this embodiment, when the e-liquid in the reservoir 200 is exhausted, there is no need to replace the atomizing device 100. Simply remove the empty reservoir 200 and connect a new one to continue vaping. Since the atomizing device 100 can be used continuously, there will be less waste, and the empty reservoir 200 can be refilled for continued use.

[0038] Compared with related technologies, the e-cigarette in this embodiment provides additional e-liquid through a detachable e-liquid reservoir 200, which increases the overall e-liquid volume of the e-cigarette. On the one hand, this reduces the user's operating costs, and on the other hand, it allows the user to use the e-cigarette for a longer period of time, reducing the need for refilling.

[0039] Furthermore, the top of the oil storage bottle 200 is provided with a connecting pipe 210 for forming an oil inlet channel 201. The connecting pipe 210 can be inserted into the connecting channel 120, so that the oil storage bottle 200 can be detachably connected to the bottom of the atomizing device 100.

[0040] The end of the connecting pipe 210 is provided with a sealing membrane to seal the oil inlet channel 201, so that the oil storage bottle 200 and the atomizing device 100 can be separated. When in use, the oil storage bottle 200 and the atomizing device 100 are reconnected.

[0041] The connecting channel 120 is provided with an oil guiding protrusion 121. When the connecting tube 210 is inserted into the connecting channel 120, the sealing film is punctured by the oil guiding protrusion 121 to connect the connecting channel 120 and the oil inlet channel 201, so that the e-liquid in the oil storage bottle 200 can flow into the atomizing chamber 130.

[0042] Furthermore, continue to refer to Figure 3As shown, the top of the atomizing device 100 is also provided with a first air intake channel 150. The mouthpiece 140 and the first air intake channel 150 are connected to each other through the atomizing core 131 in the atomizing chamber 130. When the user sucks on the mouthpiece 140, he / she draws in external air through the first air intake channel 150. The airflow generated at this time can carry the aerosol generated by the atomizing core 131, thereby enabling the user to complete the inhalation action. The first air intake channel 150 is provided with an air regulating valve 160, which is used to regulate the amount of air entering the first air intake channel 150 to adjust the draw resistance of the electronic cigarette.

[0043] Continue to refer to Figure 3 As shown, the first side 101 of the atomizing device 100 has a first airflow channel 102 communicating with the first air intake channel 150, and the second side 301 of the power supply device 300 has a second airflow channel 302. The power supply device 300 has a mounting groove 320 communicating with the second airflow channel 302, and a microphone 330 is installed in the mounting groove 320. When the first side 101 of the atomizing device 100 and the second side 301 of the power supply device 300 are connected, the first airflow channel 102 and the second airflow channel 302 are also interconnected. Thus, the airflow generated by the user sucking the mouthpiece 140 can trigger the microphone 330, thereby causing the battery to supply power to the atomizing core 131.

[0044] Optionally, the electronic cigarette in this embodiment may further include a housing 400 for enclosing the atomizing device 100 and the oil reservoir 200, such as... Figure 3 As shown, the top shell wall of the housing 400 is provided with an insertion interface 401, and the oil storage bottle 200 and the atomizing device 100 connected to each other can be placed in the housing 400 in sequence through the insertion interface 401.

[0045] The housing 400 has a first side shell wall 402 opposite to the first side portion 101 of the atomizing device 100, and the first side shell wall 402 has a first through hole 403 and a second through hole 404.

[0046] The first through hole 403 allows the first conductive contact 110 to be exposed outside the housing 400, and the second through hole 404 allows the first airflow channel 102 to be exposed outside the housing 400. After the atomizing device 100 and the oil reservoir 200 are enclosed by the housing 400, the first side 101 of the atomizing device 100 is detachably connected to the second side 301 of the power supply device 300 through the first side shell wall 402. For example, a first magnetic member 501 is provided on the side of the first side shell wall 402 facing away from the atomizing device 100, and a second magnetic member 502 that cooperates with the first magnetic member 501 is provided on the second side 301 of the power supply device 300. Of course, snap-fit ​​or splicing methods can also be used, but are not limited to these.

[0047] Since the first side shell wall 402 has a first through hole 403, after the first side 101 of the atomizing device 100 is detachably connected to the second side 301 of the power supply device 300 through the first side shell wall 402, the first conductive contact 110 can contact the second conductive contact 310 through the first through hole 403, thereby realizing the electrical connection between the first conductive contact 110 and the second conductive contact 310. The first airflow channel 102 is connected to the second airflow channel 302 through the second through hole 404, so that the microphone 330 can be triggered when the user sucks the mouthpiece 140.

[0048] Furthermore, to prevent the atomizing device 100 and the oil reservoir 200 from detaching from the housing 400, the bottom of the oil reservoir 200 and the bottom wall of the housing 400 facing the insertion interface 401 are detachably connected. For example, as shown... Figure 3 As shown, the bottom of the oil storage bottle 200 is provided with a third magnetic attraction 503, while the inner side of the bottom shell of the housing 400 is provided with a fourth magnetic attraction 504 that matches the third magnetic attraction 503.

[0049] Example 2

[0050] The difference between this embodiment and Embodiment 1 is the location where the air intake channel is formed. For example... Figure 4 As shown, in this embodiment, the atomizing device 100 is provided with a mouthpiece 140 at the top, and the first side 101 of the atomizing device 100 is provided with a third airflow channel 103. The mouthpiece 140 and the third airflow channel 103 are connected to each other through the atomizing core 131 in the atomizing chamber 130.

[0051] The power supply device 300 has a fourth airflow channel 303 on its second side 301. The power supply device 300 has a mounting groove 320 communicating with the fourth airflow channel 303, and a microphone 330 is installed in the mounting groove 320. The power supply device 300 also has a second air intake channel 304. Exemplarily, the second air intake channel 304 can be formed on the top of the power supply device 300. The second air intake channel 304 is connected to the fourth airflow channel 303, and an air regulating valve 160 is provided in the second air intake channel 304.

[0052] When the first side 101 of the atomizing device 100 is connected to the second side 301 of the power supply device 300, the third airflow channel 103 and the fourth airflow channel 303 are interconnected, so that when the user sucks on the mouthpiece 140, he can inhale external air and trigger the microphone 330 at the same time.

[0053] Continue to refer to Figure 4 As shown, similar to Embodiment 1 above, when the electronic cigarette in this embodiment also includes a housing 400, the top shell wall of the housing 400 is provided with an insertion interface 401, and the oil storage bottle 200 and the atomizing device 100 connected to each other can be placed in the housing 400 in sequence through the insertion interface 401.

[0054] The housing 400 has a first side shell wall 402 opposite to the first side portion 101. The first side shell wall 402 has a first through hole 403 and a second through hole 404. The first through hole 403 is used to expose the first conductive contact portion 110 to the housing 400, and the second through hole 404 is used to expose the third airflow channel 103 to the housing 400.

[0055] The first side 101 of the atomizing device 100 is detachably connected to the second side 301 of the power supply device 300 through the first side shell wall 402, so that the first conductive contact 110 contacts the second conductive contact 310 through the first through hole 403, thereby realizing the electrical connection between the first conductive contact 110 and the second conductive contact 310. The third airflow channel 103 is connected to the fourth airflow channel 303 through the second through hole 404, so that the microphone 330 can be triggered when the user sucks on the mouthpiece 140.

[0056] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
