[0056] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0057] See attached Figure 1-14 , an electronic cigarette in an embodiment of the utility model.

[0058] The electronic cigarette includes an electronic cigarette body 100 and a plurality of oil tanks 2, wherein the oil tanks 2 are oil tanks 2 for storing tobacco oil. The electronic cigarette body 100 includes a main body 1 and an atomizer core 3 disposed in the main body 1. The main body 1 is provided with a plurality of mounting cavities 10 for mounting the oil tank 2 on the side of the atomizer core 3, and a mounting opening 121 for mounting the oil tank 2 in the mounting cavity 10 is provided on the side wall of the main body 1. The oil tank 2 is provided with an oil outlet 217 connected to the interior at a position near the bottom, and the atomizer core 3 is provided with an oil inlet 331. When the oil tank 2 is assembled into the mounting cavity 10, the oil tank 2 and the atomizer core 3 are arranged horizontally side by side, and the oil outlet 217 is connected to the oil inlet 331.

[0059] In this embodiment, a mounting cavity 10 is reserved on the electronic cigarette body 100 for subsequent installation of the oil tank 2. Thus, when the oil tank 2 is assembled into the mounting cavity 10, the smoke oil in the oil tank 2 can be placed into the atomizer core 3 through the oil outlet hole 217 and the oil inlet hole 331, thereby adding smoke oil to the atomizer core 3 in the electronic cigarette body 100, thereby increasing the number of puffs of the electronic cigarette and the use time of the electronic cigarette body 100. In addition, in this embodiment, an installation opening 121 is provided on the side wall of the main body 1. When the user needs to add smoke oil, the oil tank 2 can be assembled into the mounting cavity 10 from the installation opening 121 on the side wall of the main body 1, which is convenient for the user to assemble.

[0060] Specifically, in one embodiment, when leaving the factory, the oil outlet 217 may be sealed with a sealant or a film to prevent the oil from leaking out. The oil tank 2 may be integrally injection molded. Alternatively, in other embodiments, the oil tank 2 may include a box body 21 and a box cover 22 connected to the box body 21, and a third sealing member 23 is provided between the box cover 22 and the box body 21 to achieve sealing of the oil tank 2. The box cover 22 is connected to the box body 21 by snaps, screws, threads, ultrasonic pressing or glue.

[0061] In one embodiment, at least one clamping block 211 is provided on the top and / or bottom of the oil tank 2, and at least part of the side surface of the clamping block 211 near the oil outlet 217 is an inclined surface. The outer contour of the oil tank 2 is matched with the installation opening 121, so that when the oil tank 2 is placed in the installation cavity 10, the clamping block 211 is clamped with the peripheral side of the installation opening 121, that is, clamped with the main body 1, to achieve the fixation of the oil tank 2. Of course, in other embodiments, the oil tank 2 can also be fixed to the installation cavity 10 by interference fit, or assembled in the installation cavity 10 by gluing, etc., and the assembly method of the oil tank 2 is not limited here.

[0062] In this embodiment, the electronic cigarette body 100 further includes a circuit board 7, a battery 9 and a microphone 73. The microphone 73, the battery 9 and the atomizer core 3 are all electrically connected to the circuit board 7. The battery 9 is used to provide power to the circuit board 7. The battery 9, the microphone 73 and the circuit board 7 are all arranged in the main body 1. The battery 9 and the circuit board 7 are all located below the atomizer core 3, and the circuit board 7 is located above the battery 9 to reduce the cross-sectional volume of the electronic cigarette body 100. The main body 1 is provided with a first air inlet 131, which is connected to the atomizer core 3 to generate airflow when the user smokes. The first air inlet 131 enters the air, and the microphone 73 detects the air pressure difference and feeds back an electrical signal to the circuit board 7. The circuit board 7 drives the atomizer core 3 to work according to the electrical signal to atomize the smoke oil. When the microphone 73 detects the air pressure change, the circuit board 7 does not drive the atomizer core 3 to work, so that the electronic cigarette can work in an orderly manner.

[0063] Of course, in other embodiments, the circuit board 7 and the battery 9 may also be arranged horizontally in parallel with the atomizer core 3, and the specific positions between the circuit board 7, the battery 9 and the atomizer core 3 are not limited here.

[0064] In actual use, the main body 1 is provided with an oil storage tank 4, and an oil cavity 410 is provided in the oil storage tank 4. The atomizer core 3 is provided in the oil storage tank 4, and the oil inlet hole 331 is connected with the oil cavity 410. The installation cavity 10 is located next to the oil storage tank 4. The oil storage tank 4 is provided with a first oil hole 413, and the oil outlet hole 217 is connected with the first oil hole 413 when the oil tank 2 is assembled into the installation cavity 10. Since the structure volume of the atomizer core 3 is small and precise, it is difficult to configure a conduit or other structures on the atomizer core 3, and it will increase the production cost. Based on this, the oil cavity 410 is used to transition the oil tank 2 to the atomizer core 3, so as to facilitate the production and manufacture of electronic cigarettes.

[0065] In one embodiment, the outer side of the atomizer core 3 is sleeved with a first shell 31, and a second oil-passing hole 311 is opened on the first shell 31.

The oil-passing cotton 32 is arranged corresponding to the position of the second oil-passing hole 311, and the oil-passing cotton 32 covers the second oil-passing hole 311. By arranging the oil-passing cotton 32 between the atomizer core 3 and the first shell 31, the oil in the oil tank 2 can be guided out from the oil outlet hole 217 by the oil-passing cotton 32, and then enter the atomizer core 3 after passing through the oil cotton 32 and the oil inlet hole 331, and the oil-passing cotton 32 can block excessive oil from being atomized to the atomizer core 3, thereby preventing the atomizer core 3 from having too much oil and preventing the user from inhaling the oil into the mouth when smoking.

[0066] The atomizer core 3 includes a second shell 33, oil-absorbing cotton 34 and a heating wire 35. The oil-absorbing cotton 34 is ring-shaped. The heating wire 35 is arranged at the bottom position in the middle of the oil-absorbing cotton 34. The oil-absorbing cotton 34 is arranged in the second shell 33, and the oil inlet hole 331 is opened in the second shell 33. The oil-absorbing cotton 34 absorbs the smoke oil, which can prevent the smoke oil in the atomizer core 3 from leaking when the oil tank 2 is not installed. And the smoke oil will gather at the bottom of the oil-absorbing cotton 34 under its own gravity, so that the smoke oil can be atomized when the heating wire 35 is heated.

[0067] In one embodiment, the position of the oil inlet hole 331 is arranged corresponding to the position of the second oil hole 311 to facilitate oil inlet. Of course, in other embodiments, the position of the oil inlet hole 331 and the position of the second oil hole 311 can be arranged in a staggered manner.

[0068] In one embodiment, the number of the second oil passage hole 311 and the number of the oil inlet hole 331 are both plural. Of course, in other embodiments, the number of the second oil passage hole 311 and the number of the oil inlet hole 331 may be one.

When the second protrusion 414 is placed in the first protrusion 215, the first sealing member 216 can conduct the oil outlet hole 217 and the first oil hole 413.

[0071] In one embodiment, the material of the first sealing member 216 is soft rubber, and the first sealing member 216 includes a first sealing ring 2162 sleeved on the first protrusion 215 and a first sealing panel 2161 covering the first sealing ring 2162. The first sealing panel 2161 is provided with a first indentation 2163, and the outer contour of the second protrusion 414 is smaller than the outer contour of the oil outlet hole 217. When the second protrusion 414 is placed in the first protrusion 215, the second protrusion 414 presses the first sealing panel 2161 to penetrate the first sealing panel 2161 along the first indentation 2163, so that the oil outlet hole 217 and the first oil through hole 413 are connected, and the first sealing panel 2161 is located between the first protrusion 215 and the second protrusion 414, so that the smoke oil in the oil tank 2 can enter the oil through cavity 410 through the oil outlet hole 217 and the first oil through hole 413.

[0072] In other embodiments, the first sealing member 216 may be directly placed in the oil outlet hole 217 . When the second protrusion 414 is placed in the first protrusion 215 , the first sealing member 216 is pushed away, so that the oil outlet hole 217 and the first oil hole 413 can be connected.

[0073] In the above embodiments, the number of the installation cavities 10 may be two, three, four, etc., and the number of the installation cavities 10 is not limited herein.
