A first oil cavity 362 for storing e-liquid is provided in the atomization core 300, and a first oil inlet hole 321 communicating with the first oil cavity 362 is formed on the atomization core 300. A second oil cavity 190 for storing e-liquid is provided in the oil bottle 100, and a first oil outlet hole 131 communicating with the second oil cavity 190 is formed on the oil bottle 100. A covering member 140 is provided on the oil bottle 100, and the covering member 140 covers the first oil outlet hole 131 when the oil bottle 100 is not installed on the atomization core 300. When the oil bottle 100 is installed on the atomization core 300, at least a part of the first oil outlet hole 131 is not covered by the covering member 140, so that the first oil outlet hole 131 communicates with the first oil inlet hole 321, so as to realize that the e-liquid in the oil bottle 100 enters the first oil cavity 362 through the first oil outlet hole 131 and the first oil inlet hole 321 for use by the atomization core 300. The atomization core 300 is detachably arranged on the main body 200, and when the atomization core 300 is installed on the main body 200, the atomization core 300 is electrically connected to the main body 200 and obtains power from the main body 200.

[0047] In this embodiment, the atomizing core 300 is detachably connected to the main unit 200, and when the atomizing core 300 is installed on the main unit 200, the atomizing core 300 is electrically connected to the main unit 200 so that the atomizing core 300 can be used after installation. And after the atomizing core 300 has been used for a certain period of time, a new atomizing core 300 can be replaced for use to prevent the problem that the carbon deposition of the heating element 343 inside the atomizing core 300 affects the taste. And this embodiment also assembles an independent oil bottle 100 to increase the capacity of the e-liquid, increase the number of puffs that the user inhales, and effectively increase the usage time of the electronic cigarette.

[0048] Specifically, one atomizing core 300 can be adapted to be used with one oil bottle 100, or one atomizing core 300 can be adapted to be used with multiple oil bottles 100 at the same time. In other embodiments, the number of atomizing cores 300 can be one or more, that is, one main unit 200 can be adapted to be used with one atomizing core 300 or multiple atomizing cores 300.

[0049] In one embodiment, a heating element 343 for atomizing the e-liquid is arranged in the first oil chamber 362, and a first conductive member 370 electrically connected to the heating element 343 is arranged on the atomizing core 300. A circuit board 250, a battery 240, a microphone 251 and a second conductive member 260 are arranged on the main unit 200. An air flow channel 280 is arranged on the main unit 200. One end of the air flow channel 280 is communicated with the inside of the atomizing core 300, and the other end of the air flow channel 280 is communicated with the external air. The circuit board 250 is electrically connected to the battery 240, the second conductive member 260 and the microphone 251 respectively. When the atomizing core 300 is installed on the main unit 200, the first conductive member 370 is electrically connected to the second conductive member 260. When the user inhales, air flows through the air flow channel 280, and the microphone 251 detects the air pressure difference and gives an electrical signal to the circuit board 250. The circuit board 250 supplies power to the heating element 343 through the second conductive member 260 and the first conductive member 370 according to this electrical signal to drive the heating element 343 to work.

[0050] Among them, the first conductive member 370 and the second conductive member 260 can be conductive columns 371, elastic thimbles or conductive elastic sheets and other parts with conductive properties.

[0051] In one embodiment, the first conductive member 370 includes a conductive base plate 372 and a conductive post 371. The conductive post 371 is electrically connected to the heating element 343, and the conductive base plate 372 is connected to the bottom of the conductive post 371. The second conductive member 260 is an elastic ejector pin. The structure of the first conductive member 370 is simple and the cost is low, so as to reduce the cost of the atomization core 300. By using the elastic ejector pin, when the atomization core 300 is installed on the main body 200, the first conductive member 370 can be stably connected to the second conductive member 260. Specifically, the conductive base plate 372 is in a plate shape, thereby increasing the contact area between the first conductive member 370 and the second conductive member 260, and facilitating the contact between the second conductive member 260 and the first conductive member 370.

[0052] Specifically, in the above embodiment, the atomization core 300 and the main body 200 can be detachably connected by means of snap fit, thread, magnetic attraction, screw, etc.

[0053] That is, a detachable structure is provided between the atomization core 300 and the main body 200. The detachable structure includes a first connecting member and a second connecting member detachably connected to the first connecting member. The first connecting member is provided on the atomization core 300, and the second connecting member is provided on the main body 200.

[0054] Specifically, a support surrounding wall 221 is provided at the top of the main body 200, an avoidance groove 344 is provided at the bottom of the atomization core 300, the first connecting member is provided on the avoidance groove 344, the second connecting member is provided on the support surrounding wall 221, the first conductive member 370 is located at the bottom of the avoidance groove 344, and the second conductive member 260 is located inside the support surrounding wall 221. When the atomization core 300 is installed on the main body 200, the support surrounding wall 221 is placed in the avoidance groove 344. Thus, the contact surface between the atomization core 300 and the main body 200 can be increased, and the connection stability between the atomization core 300 and the main body 200 can be improved.

[0055] In one embodiment, the first connecting member can be a first card slot 341, and the second connecting member can be a first card block 223. When the atomization core 300 is installed on the main body 200, the first card block 223 is placed in the first card slot 341 to achieve the detachable connection between the atomization core 300 and the main body 200.

[0056] In actual use, gaps 222 can also be provided on both sides of the first card block 223 in the support surrounding wall 221. By using the gaps 222, the position of the first card block 223 can be made elastic, which is convenient for the first card block 223 to be placed in the first card slot 341 or to be detached from the first card slot 341. Specifically, the top surface and the bottom surface of the first card block 223 both have inclined surfaces or arc surfaces, so as to facilitate the first card block 223 to be placed in the first card slot 341 or to be detached from the first card slot 341. In other embodiments, the first connecting member can be the first card block 223, and the second connecting member can be the first card slot 341.

[0057] In one embodiment, the first connecting member may be the first thread 342, and the second connecting member may be the second thread 225. The first thread 342 is located on the side wall of the avoidance groove 344, and the second thread 225 is located on the outer side wall of the support surrounding wall 221, which can also achieve the detachable connection between the atomization core 300 and the main unit 200. For example, Figure 6-7 In another embodiment, the first connecting member may also be the first magnetic member 345, and the second connecting member is the second magnetic member 201. For example, Figure 8 when the atomization core 300 is installed on the main unit 200, the first magnetic member 345 is adsorbed to the second magnetic member 201, which can also achieve the detachable connection between the atomization core 300 and the main unit 200.

The first oil inlet hole 321 is located on the first atomization outer shell 320. The second atomization outer shell 360 is provided with a second oil inlet hole 361 at a position corresponding to the first oil inlet hole 321.

The first conductive member 370 is disposed on the atomization bottom shell 340 and beside the flue 390. Specifically, the first conductive member 370 can be fixed on the atomization bottom shell 340 by means of gluing, interference fit, screws, etc. By using the first oil absorption cotton 350 to adsorb the e-liquid, after the atomization core 300 is installed on the main unit 200, it can be used independently. By disposing the second oil absorption cotton 330 between the first oil inlet hole 321 and the second oil inlet hole 361, the e-liquid on the oil bottle 100 can be introduced into the first oil cavity 362, but it can also effectively limit the e-liquid in the oil bottle 100 from entering the first oil cavity 362, playing a role in current limiting, preventing the e-liquid from accumulating on the first oil absorption cotton 350, and preventing the user from inhaling the e-liquid into the mouth when smoking. And through the second oil absorption cotton 330, it can also prevent the e-liquid in the first oil absorption cotton 350 from leaking out, playing a role in preventing oil leakage.

[0059] In practical applications, a mouthpiece 40 is provided at the top of the atomizing core 300, that is, the mouthpiece 40 is provided on the first atomizing outer shell 320 for the user to inhale the smoke.

[0063] In one embodiment, a through hole 180 penetrating the oil bottle 100 from top to bottom is provided on the oil bottle 100. When the oil bottle 100 is installed on the atomizing core 300, the atomizing core 300 passes through the through hole 180 to improve the installation stability of the oil bottle 100.

[0067] In one embodiment, an oil passage cavity 192 is formed between the covering member 140 and the bottom shell 170 of the oil bottle. The third oil inlet hole 146 and the second oil outlet hole 145 are both communicated with the oil passage cavity 192. Thus, when the oil bottle 100 is assembled onto the atomization core 300 and the covering member 140 rotates relative to the oil bottle 100, the e-liquid in the oil bottle 100 flows out from the first oil outlet hole 131, enters the oil passage cavity 192 through the third oil inlet hole 146, and then enters the atomization core 300 after passing through the second oil outlet hole 145 and the first oil inlet hole 321. By using the oil passage cavity 192, the space for e-liquid circulation can be increased, preventing the problem that the e-liquid forms a film between the third oil inlet hole 146 and the second oil outlet hole 145, which makes it difficult for the e-liquid to flow, thereby improving the fluidity of the e-liquid.

[0068] Specifically, the covering member 140 includes a first upper panel 141 and a first surrounding wall 142 located below the first upper panel 141. The third oil inlet hole 146 is located on the first upper panel 141. The second oil outlet hole 145 and the first clamping groove 341 are both located on the first surrounding wall 142. The second clamping block 252 is located on the atomization core 300. The bottom shell 170 of the oil bottle includes a second surrounding wall 172 and a lower panel 171 connected to the bottom of the second surrounding wall 172. The first surrounding wall 142 is placed inside the second surrounding wall 172 and above the lower panel 171. A second sealing member 130 is arranged between the first upper panel 141 and the oil guiding member 120 to prevent the e-liquid from leaking out through the gap 222 between the first upper panel 141 and the oil guiding member 120. A third sealing member 150 is arranged between the bottom of the first surrounding wall 142 and the lower panel 171 to prevent the e-liquid from leaking out through the gap 222 between the bottom of the first surrounding wall 142 and the lower panel 171, achieving a sealing effect. The oil passage cavity 192 is formed by surrounding the first surrounding wall 142, the lower panel 171, the second surrounding wall 172, and the first upper panel 141. Thus, the oil passage cavity 192 is formed. The third oil inlet hole 146 also penetrates through the second sealing member 130 to enable the third oil inlet hole 146 to communicate with the oil passage cavity 192. Moreover, the second sealing member 130 and the third sealing member 150 can provide frictional force for the rotation of the covering member 140 to prevent the covering member 140 from rotating freely.

[0069] In one embodiment, a first limiting post 173 is arranged on the lower panel 171, and a movable hole 144 is formed on the first upper panel 141. One end of the first limiting post 173 passes through the third sealing member 150 and the movable hole 144 and is placed on the second sealing member 130. In this way, when the covering member 140 rotates relative to the oil bottle 100, under the action of the first limiting post 173, the second sealing member 130 and the third sealing member 150 can be prevented from rotating together.

[0070] In one embodiment, a second limiting groove 133 is provided on the second seal 130, and a third limiting post 121 is provided at the bottom of the oil guiding member 120. The third limiting post 121 is placed in the second limiting groove 133. By placing the third limiting post 121 in the second limiting groove 133, the relative positions of the second seal 130 and the oil guiding member 120 can be fixed and will not be affected by the rotation of the covering member 140 relative to the oil bottle 100.

[0071] In one embodiment, the bottom of the second seal 130 protrudes downward to form a first bump 132, the first oil outlet hole 131 penetrates through the first bump 132, and the top surface of the first upper panel 141 is recessed downward to form a first groove 143. In the initial state, at least a part of the first bump 132 is placed in the first groove 143, and when the second oil outlet hole 145 is communicated with the first oil inlet hole 321, at least a part of the first bump 132 is placed in the third oil inlet hole 146. By using the first bump 132, the sealing performance between the second seal 130 and the covering member 140 can be effectively improved, and by matching the first bump 132 with the third oil inlet hole 146, there can be a positioning effect when the covering member 140 rotates relative to the oil bottle 100 until the second oil outlet hole 145 is communicated with the first oil inlet hole 321, so as to remind the user that the second oil outlet hole 145 and the first oil inlet hole 321 have been communicated and there is no need to continue rotating the oil bottle 100.

[0072] In one embodiment, the oil bottle housing 110 includes a first annular wall 113, a second annular wall 112 located inside the first annular wall 113, and a second upper panel 111 connected to the first annular wall 113 and the second annular wall 112 on both sides respectively. The through hole 180 is located in the middle of the second annular wall 112, and the oil guiding member 120 is sleeved on the outer side of the second annular wall 112. Thus, the oil bottle 100 can be in a ring shape and is fixed on the atomization core 300 by a sleeving method. Part of the second seal 130 is sleeved on the outer side of the second annular wall 112, and part of the second seal 130 is located between the second annular wall 112 and the first upper panel 141. By using the second seal 130, it can prevent the e-liquid from leaking from the oil guiding member 120 and can also prevent the leakage between the oil guiding member 120 and the covering member 140, playing a sealing role. The second surrounding wall 172 is placed inside the first annular wall 113, and the first seal 160 is arranged between the second surrounding wall 172 and the first annular wall 113. Based on the above structure, the oil bottle 100 can be manufactured. Specifically, the second surrounding wall 172 and the first annular wall 113 can also be connected by means of buckles, threads, etc.

[0073] In other embodiments, a pushing member is provided on the atomizing core 300. The pushing member can be arranged on the third connecting member 310. When the oil bottle 100 is installed on the atomizing core 300, the covering member 140 abuts against the pushing member and is pushed upward to open the first oil outlet hole 131. That is, after the oil bottle 100 is assembled to the atomizing core 300, the first oil outlet hole 131 can be directly communicated with the first oil inlet hole 321 without rotation, which is convenient for the user to operate.
