[0039] Figs. 1-13 show an electronic cigarette assembly with a replaceable atomizing core in embodiments of the present invention.

[0040] The electronic cigarette assembly with the replaceable atomizing core includes a main body 200, at least one atomizing core 300, and at least one liquid bottle 100. The atomizing core 300 is internally equipped with a first liquid storage cavity 362 for storing tobacco liquid. First liquid inlet holes 321 communicated with the first liquid storage cavity 362 are defined in the atomizing core 300. The liquid bottle 100 is internally equipped with a second liquid storage cavity 190 for storing tobacco liquid. First liquid outlet holes 131 communicated with the second liquid storage cavity 190 are defined in the liquid bottle 100. The liquid bottle 100 is equipped with a covering member 140. The covering member 140 covers the first liquid outlet holes 131 when the liquid bottle 100 is not installed on the atomizing core 300. When the liquid bottle 100 is installed on the atomizing core 300, each of the first liquid outlet holes 131 is at least partially not covered by the covering member 140, so that the first liquid outlet holes 131 are in communication with the first liquid inlet holes 321, so as to allow the tobacco liquid in the liquid bottle 100 to enter the first liquid storage cavity 362 after passing through the first liquid outlet holes 131 and the first liquid inlet holes 321 for use by the atomizing core 300. The atomizing core 300 is detachably installed on the main body 200, and when the atomizing core 300 is installed on the main body 200, the atomizing core 300 is electrically connected to the main body 200 and powered from the main body 200.

[0041] In this embodiment, the atomizing core 300 is detachably connected to the main body 200, and when the atomizing core 300 is installed on the main body 200, the atomizing core 300 is electrically connected to the main body 200 to make the atomizing core 300 usable after installation. After the atomizing core 300 is used for a period of time, the atomizing core 300 can be replaced with a new one for use, so as to prevent the carbon deposition of a heating element 343 inside the atomizing core 300 from affecting the taste. Moreover, in this embodiment, by assembling the independent liquid bottle 100, the capacity of the tobacco liquid is also increased, a total number of puffs is increased for a user, and the service life of the electronic cigarette is effectively improved.

[0042] Specifically, one atomizing core 300 can be adapted for use with one liquid bottle 100, or one atomizing core 300 can be adapted for use with a plurality of liquid bottles 100 simultaneously. In other embodiments, a total number of the atomizing core 300 can be one or more, i.e. a main body 200 can be adapted for use with one atomizing core 300 or a plurality of atomizing cores 300.

[0043] In one embodiment, the heating element 343 is provided inside the first liquid storage cavity 362 for atomizing the tobacco liquid. The atomizing core 300 is equipped with a first conductive member 370 electrically connected to the heating element 343. The main body 200 is equipped with a circuit board 250, a battery 240, a pneumatic switch 251, and second conductive members 260. The main body 200 is equipped with an airflow channel 280. One end of the airflow channel 280 is in communication with an interior of the atomizing core 300, and an opposite end of the airflow channel 280 is in communication with external air. The circuit board 250 is respectively electrically connected to the battery 240, the second conductive members 260, and the pneumatic switch 251. When the atomizing core 300 is installed on the main body 200, the first conductive member 370 is electrically connected to the second conductive members 260, so that when the user puffs, there is air circulation in the airflow channel 280, and the pneumatic switch 251 detects a pressure difference and sends an electrical signal to the circuit board 250. Based on this electrical signal, the circuit board 250 supplies power to the heating element 343 through the second conductive members 260 and the first conductive member 370 to drive the heating element 343 to work.

[0044] The first conductive member 370 and the second conductive members 260 can be conductive parts such as conductive columns 371, elastic pins, or electrically conductive elastic sheets.

[0045] In one embodiment, the first conductive member 370 includes a conductive bottom plate 372 and a conductive column 371. The conductive column 371 is electrically connected to the heating element 343, the conductive bottom plate 372 is connected to a bottom portion of the conductive column 371, and the second conductive members 260 are elastic pins. The first conductive member 370 has a simple structure and low cost to reduce the cost of the atomizing core 300. By using the elastic pins, when the atomizing core 300 is installed on the main body 200, the first conductive member 370 can be stably connected to the second conductive members 260. Specifically, the conductive bottom plate 372 is in a plate shape, thereby increasing the contact area between the first conductive member 370 and the second conductive members 260, facilitating contact between the second conductive members 260 and the first conductive member 370.

[0046] Specifically, in the above embodiments, the atomizing core 300 can be detachably connected to the main body 200 through buckles, threads, magnetic attraction, screws, and other means.

[0047] A detachable structure is arranged between the atomizing 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 arranged on the atomizing core 300, and the second connecting member is arranged on the main body 200.

[0048] Specifically, a top portion of the main body 200 is equipped with a supporting enclosure wall 221, and a bottom portion of the atomizing core 300 is equipped with an avoidance slot 344. The first connecting member is arranged on the avoidance slot 344, and the second connecting member is arranged on the supporting enclosure wall 221. The first conductive member 370 is positioned at a bottom of the avoidance slot 344, and the second conductive members 260 are positioned on an inner side of the supporting enclosure wall 221. When the atomizing core 300 is installed on the main body 200, the supporting enclosure wall 221 is placed in the avoidance slot 344, which can increase a contact surface between the atomizing core 300 and the main body 200, and improve the stability of the connection between the atomizing core 300 and the main body 200.

[0049] In one embodiment, the first connecting member can be a first fixing slot 341, and the second connecting member can be a first convex block 223. When the atomizing core 300 is installed on the main body 200, the first convex block 223 is placed in the first fixing slot 341 to achieve a detachable connection between the atomizing core 300 and the main body 200.

[0050] In practical application, the first supporting enclosure wall 221 can also be equipped with gaps 222 on both sides of the first convex block 223. By using the gaps 222, the first convex block 223 can be more flexible, making it convenient for the first convex block 223 to be placed inside the first fixing slot 341 or detached from the first fixing slot 341. Specifically, both a top surface and a bottom surface of the first convex block 223 are provided with a sloping surface or a curved surface, so that the first convex block 223 can be placed inside the first fixing slot 341 or detached from the first fixing slot 341. In other embodiments, the first connecting member can be the first convex block 223, and the second connecting member can be the first fixing slot 341.

[0051] In one embodiment, the first connecting member can be a first thread 342, the second connecting member can be a second thread 225, the first thread 342 is positioned on a side wall of the avoidance slot 344, and the second thread 225 is positioned on an outer side wall of the supporting enclosure wall 221, which can also achieves the detachable connection between the atomizing core 300 and the main body 200, as shown in Figs. 6-7. In another embodiment, the first connecting member can also be a first magnetic attraction member 345, and the second connecting member can be a second magnetic attraction member 201, as shown in Fig. 8. When the atomizing core 300 is installed on the main body 200, the first magnetic attraction member 345 attracts with the second magnetic attraction member 201, which can also achieve detachable connection between the atomizing core 300 and the main body 200. At least one of the first magnetic attraction member 345 and the second magnetic attraction member 201 is a magnet.

[0052] In one embodiment, the atomizing core 300 includes a first outer atomizing housing 320, first liquid absorbing cotton 350, second liquid absorbing cotton 330, a second outer atomizing housing 360, a top atomizing housing 380, and a bottom atomizing housing 340. The second outer atomizing housing 360 is positioned inside the first outer atomizing housing 320, the second liquid absorbing cotton 330 is positioned between the first outer atomizing housing 320 and the second outer atomizing housing 360, the first liquid absorbing cotton 350 is positioned inside the second outer atomizing housing 360, and the heating element 343 is arranged near a bottom portion of the second liquid absorbing cotton 330. The top atomizing housing 380 and the bottom atomizing housing 340 are respectively connected to an upper end and a lower end of the second outer atomizing housing 360. The first liquid storage cavity 362 is surrounded and formed by the second outer atomizing housing 360, the bottom atomizing housing 380 and the bottom atomizing housing 340. The first liquid inlet holes 321 are positioned on the first outer atomizing housing 320, and the second outer atomizing housing 360 is provided with second liquid inlet holes 361 at positions corresponding to the first liquid inlet holes 321. The second liquid absorbing cotton 330 covers the first liquid inlet holes 321 and the second liquid inlet holes 361. A middle of the atomizing core 300 is provided with an aerosol passage 390, and the aerosol passage 390 runs through itself. The aerosol passage 390 is in communication with the airflow channel 280. The aerosol passage 390 runs through the first liquid absorbing cotton 350, the top atomizing housing 380, and the bottom atomizing housing 340. The first conductive member 370 is arranged on the bottom atomizing housing 340 and positioned next to the aerosol passage 390. Specifically, the first conductive member 370 can be fixed on the bottom atomizing housing 340 by gluing, interference fit, screws, and other methods. By using the first liquid absorbing cotton 350 to absorb the tobacco liquid, after the atomizing core 300 is installed on the main body 200, the electronic cigarette assembly can be used independently without being used in conjunction with the liquid bottle 100. The second liquid absorbing cotton 330 is configured between the first liquid inlet holes 321 and the second liquid inlet holes 361, which can guide the tobacco liquid from the liquid bottle 100 into the first liquid storage cavity 362, but can also effectively limit the tobacco liquid from the liquid bottle 100 from entering the first liquid storage cavity 362, playing a flow limiting role, preventing tobacco liquid from accumulating on the first liquid absorbing cotton 350, and preventing the user from inhaling the tobacco liquid into mouth together when puffing. Moreover, through the second liquid absorbing cotton 330, the tobacco liquid inside the first liquid absorbing cotton 350 can be prevented from leaking out, thereby playing a role in preventing liquid leakage.

[0053] In practical application, a top portion of the atomizing core 300 is equipped with a mouthpiece 400, that is, the first outer atomizing housing 320 is equipped with the mouthpiece 400 for the user to inhale the aerosol. The main body 200 includes an outer main body housing 210, a bracket 220, and a bottom main body housing 230. The bracket 220 is positioned inside the outer main body housing 210. The battery 240 is installed inside the bracket 220. The circuit board 250 is positioned below the battery 240, and the pneumatic switch 251 is arranged on the circuit board 250. Both the bottom main body housing 230 and the circuit board 250 are equipped with an air inlet hole 231. The bracket 220 is equipped with an air outlet hole 244. The airflow channel 280 is formed by the air inlet hole 231, the air outlet hole 244, and a gap between the bracket 220 and the outer main body housing 210. The second conductive members 260 are arranged at a top end of the bracket 220, and the structure of the main body 200 can be made more compact by using the bracket 220. Of course, in other embodiments, the bracket 220 can also be a top housing of the main body 200, and the structure of the main body 200 is not limited here.

[0054] In one embodiment, the main body 200 can also be equipped with a light emitting unit electrically connected to the circuit board 250. The light emitting unit emits light to serve as a reminder or decoration during the use of the product in this embodiment. Specifically, the light emitting unit can be an LED light or a light bead. The battery 240 can be recharged. The circuit board 250 is equipped with a charging interface 232. The charging interface 232 is used for connecting to external power supply, and the battery 240 can be charged through the circuit board 250.

[0055] In the above embodiments, the liquid bottle 100 is detachably installed on the atomizing core 300, or the liquid bottle 100 cannot be removed after being installed on the atomizing core 300.

[0056] In one embodiment, the top portion of the main body 200 is provided with a first position limiting slot 270 for limiting a position of the liquid bottle 100. When the atomizing core 300 is installed on the main body 200 and the liquid bottle 100 is assembled onto the atomizing core 300, a bottom end of the liquid bottle 100 is placed in the first position limiting slot 270 to increase the stability of the product assembly in this embodiment.

[0057] In one embodiment, the liquid bottle 100 is provided with a perforating hole 180, and the perforating hole 180 runs through itself from top to bottom. When the liquid bottle 100 is installed on the atomizing core 300, the atomizing core 300 passes through the perforating hole 180 to improve the stability of the installation of the liquid bottle 100.

[0058] When the liquid bottle 100 is assembled onto the atomizing core 300, a joint structure is provided between the covering member 140 and the atomizing core 300. The joint structure includes a second fixing slot 147 and a second convex block 311. The second convex block 311 is placed inside the second fixing slot 147 when the liquid bottle 100 is assembled onto the atomizing core 300. In this way, when the liquid bottle 100 is assembled onto the atomizing core 300, the second convex block 311 is placed in the second fixing slot 147 to fix a relative position between the covering member 140 and the atomizing core 300. Therefore, when the liquid bottle 100 rotates relative to the atomizing core 300, the covering member 140 can rotate relative to the liquid bottle 100, so that the first liquid outlet holes 131 are opened, and the first liquid outlet holes 131 are in communication with the first liquid inlet holes 321.

[0059] For the convenience of manufacturing the atomizing core 300, the atomizing core 300 further includes a third connecting member 310. The second convex block 311 is arranged on the third connecting member 310. The third connecting member 310 is sleeved on the first outer atomizing housing 320, and the third connecting member 310 can be fixed on the first outer atomizing housing 320 by rivet connection.

[0060] In practical application, in order to improve the compactness of the structure of the liquid bottle 100 and facilitate the production of the liquid bottle 100, the liquid bottle 100 includes: an outer liquid bottle housing 110 with an opening at a bottom portion, a bottom liquid bottle housing 170 arranged at the opening, a liquid guiding member 120 arranged inside the outer liquid bottle housing 110, and a first sealing member 160 arranged between the bottom liquid bottle housing 170 and the outer liquid bottle housing 110. The second liquid storage cavity 190 is formed by the liquid guiding member 120 and the outer liquid bottle housing 110. The first liquid outlet holes 131 are positioned on the liquid guiding member 120, and the covering member 140 is positioned below the liquid guiding member 120. The covering member 140 is provided with third liquid inlet holes 146 and second liquid outlet holes 145. The third liquid inlet holes 146 are in communication with the second liquid outlet holes 145. The third liquid inlet holes 146 are not in communication with the first liquid outlet holes 131 when in an initial state. The third liquid inlet holes 146 are in communication with the first liquid outlet holes 131 after the covering member 140 rotates relative to the liquid guiding member 120. The second liquid outlet holes 145 are in communication with the first liquid inlet holes 321 when the liquid bottle 100 is assembled onto the atomizing core 300. When the liquid bottle 100 is assembled onto the atomizing core 300 and the covering member 140 rotates relative to the liquid bottle 100, the tobacco liquid positioned inside the liquid bottle 100 can flow out from the first liquid outlet holes 131, and enter the atomizing core 300 after sequentially passing through the third liquid inlet holes 146, the second liquid outlet holes 145, and the first liquid inlet holes 321.

[0061] In one embodiment, a liquid passing cavity 192 is formed between the covering member 140 and the bottom liquid bottle housing 170. The third liquid inlet holes 146 and the second liquid outlet holes 145 are both in communication with the liquid passing cavity 192. Therefore, when the liquid bottle 100 is assembled onto the atomizing core 300 and the covering member 140 rotates relative to the liquid bottle 100, the tobacco liquid inside the liquid bottle 100 flows out from the first liquid outlet holes 131, enters the liquid passing cavity 192 through the third liquid inlet holes 146, and then enters the atomizing core 300 after passing through the second liquid outlet holes 145 and the first liquid inlet holes 321. By utilizing the liquid passing cavity 192, a space for the circulation of the tobacco liquid can be increased, preventing the formation of a film between the third liquid inlet holes 146 and the second liquid outlet holes 145 from leading to difficulties in the flow of the tobacco liquid, thereby further improving the fluidity of the tobacco liquid.

[0062] Specifically, the covering member 140 includes a first upper panel 141 and a first enclosure wall 142 positioned below the first upper panel 141. The third liquid inlet holes 146 are positioned on the first upper panel 141. The second liquid outlet holes 145 and the first fixing slot 341 are both positioned on the first enclosure wall 142. The second convex block 311 is positioned on the atomizing core 300. The bottom liquid bottle housing 170 includes a second enclosure wall 172 and a lower panel 171 connected to a bottom portion of the second enclosure wall 172. The first enclosure wall 142 is placed inside the second enclosure wall 172 and above the lower panel 171. A second sealing member 130 is installed between the first upper panel 141 and the liquid guiding member 120 to prevent tobacco liquid from leaking out from a gap between the first upper panel 141 and the liquid guiding member 120. A third sealing member 150 is installed between a bottom portion of the first enclosure wall 142 and the lower panel 171, so as to prevent tobacco liquid from leaking out from a gap between the bottom portion of the first enclosure wall 142 and the lower panel 171, thereby achieving a sealing effect. The liquid passing cavity 192 is surrounded and formed by the first enclosure wall 142, the lower panel 171, the second enclosure wall 172, and the first upper panel 141. The third liquid inlet holes 146 also penetrate through the second sealing member 130 to achieve communication between the third liquid inlet holes 146 and the liquid passing cavity 192. Furthermore, the use of the second sealing member 130 and the third sealing member 150 can provide friction for the rotation of the covering member 140, preventing the covering member 140 from rotating randomly.

[0063] In one embodiment, first position limiting columns 173 are provided on the lower panel 171, and moving holes 144 are defined in the first upper panel 141. One end of the first position limiting column 173 passes through the third sealing member 150 and the moving holes 144, and then is placed on the second sealing member 130. In this way, when the covering member 140 rotates relative to the liquid bottle 100, under the action of the first position limiting columns 173, the second sealing member 130 and the third sealing member 150 can be prevented from rotating together.

[0064] In one embodiment, second position limiting slots 133 are defined in the second sealing member 130. Third position limiting columns 121 are provided at a bottom portion of the liquid guiding member 120. The third position limiting columns 121 are placed inside the second position limiting slots 133. By placing the third position limiting columns 121 in the second position limiting slots 133, the relative position between the second sealing member 130 and the liquid guiding member 120 can be fixed, without being affected by the rotation of the covering member 140 relative to the liquid bottle 100.

[0065] In one embodiment, a bottom portion of the second sealing member 130 protrudes downwards to form first protrusions 132. The first liquid outlet holes 131 penetrate through the first protrusions 132. A top surface of the first upper panel 141 is depressed downwards to form first slots 143. Each of the first protrusions 132 is at least partially positioned in a corresponding first slot 143 when in an initial state. Each of the first protrusions 132 is at least partially positioned in a corresponding third liquid inlet hole 146 when the second liquid outlet holes 145 are in communication with the first liquid inlet holes 321. By utilizing the first protrusions 132, the sealing between the second sealing member 130 and the covering member 140 can be effectively improved. Moreover, when the covering member 140 rotates relative to the liquid bottle 100 to a position where the second liquid outlet holes 145 are in communication with the first liquid inlet holes 321, by using the first protrusions 132 in conjunction with the third liquid inlet holes 146, a positioning role is played to remind the user that the second liquid outlet holes 145 are already communicated with the first liquid inlet holes 321 and there is no need to continue rotating the liquid bottle 100.

[0066] In one embodiment, the outer liquid bottle housing 110 includes a first annular wall 113, a second annular wall 112, and a second upper panel 111. The second annular wall 112 is positioned within the first annular wall 113. Both sides of the second upper panel 111 are respectively connected to the first annular wall 113 and the second annular wall 112. The perforating hole 180 is positioned in a middle of the second annular wall 112. The liquid guiding member 120 is sleeved on an outer side of the second annular wall 112. As a result, the liquid bottle 100 can be arranged in an annular shape and fixed on the atomizing core 300 in a sleeving manner. Part of the second sealing member 130 is sleeved on the outer side of the second annular wall 112. Part of the second sealing member 130 is positioned between the second annular wall 112 and the first upper panel 141. By using the second sealing member 130, the tobacco liquid can be prevented from leaking from the liquid guiding member 120, and liquid leakage between the liquid guiding member 120 and the covering member 140 can be prevented, thereby playing a sealing role. The second enclosure wall 172 is placed inside the first annular wall 113, and the first sealing member 160 is provided between the second enclosure wall 172 and the first annular wall 113. Based on the above structure, the liquid bottle 100 can be produced and manufactured. Specifically, the connection between the second enclosure wall 172 and the first annular wall 113 can also be achieved by means of buckles, threads, etc.

[0067] 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 liquid bottle 100 is installed on the atomizing core 300, the covering member 140 abuts against the pushing member and is pushed upwards to open the first liquid outlet holes 131. That is, after the liquid bottle 100 is assembled on the atomizing core 300, the first liquid outlet holes 131 can be directly communicated with the first liquid inlet holes 321 without rotation, which is convenient for the user to operate.

[0068] The above description only describes embodiments of the present disclosure, and is not intended to limit the present disclosure; various modifications and changes can be made to the present disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of the present disclosure are intended to be included within the scope of the present disclosure.
