[0032] To solve relevant technical problems, such as Figure 1 As shown, the embodiment of the utility model provides an electronic cigarette, comprising:

[0033] A base 1, wherein a first mounting groove 2 is disposed at an upper end of the base 1, and an opening structure 4 is disposed on a first side wall 3 of the first mounting groove 2;

[0034] The atomizer body 6 is detachably plugged into the first mounting groove 2 in the vertical direction, and a portion of the atomizer body 6 passes through the opening structure 4 and is provided with an oil storage structure 8. A positioning groove 62 is vertically provided on the side surface of the atomizer body 6 opposite to the first side wall 3, and the first side wall 3 is at least partially inserted into the positioning groove 62 to position the atomizer body 6 in the horizontal direction.

[0035] In this embodiment, the base 1 and the atomizer body 6 are separate structures, and an electric control component is configured in the base 1. After the atomizer body 6 is installed on the base 1, the electric control component maintains electrical connection with the atomizer core electrode in the atomizer body 6, and the atomizer core is controlled to heat up under the action of the electric control component so as to atomize the smoke oil in the atomizer body 6. In order to facilitate long-term use, in this embodiment, an oil storage structure 8 is installed on one side of the atomizer body 6, and the oil storage structure 8 can be an oil storage bottle 82 or other oil storage device installed on the atomizer body 6. In order to reduce the horizontal space occupation, the oil storage structure 8 is generally installed on the atomizer body 6 in the vertical direction.

[0036] On this basis, in order to facilitate the assembly of the atomizer body 6 and the base 1, a first mounting groove 2 is provided at the upper end of the base 1 in this embodiment, and an opening structure 4 is provided on the first side wall 3 of the first mounting groove 2.

[0045] To protect the oil storage bottle 82 , the atomizer body 6 in this embodiment further includes a bottle shell 81 , which is sleeved on the oil storage bottle 82 , and a snap-fit ​​flange 17 that snaps with the upper end of the bottle shell 81 is provided on the mounting portion 61 .

[0046] like Figure 1 and Figure 2 As shown, according to another aspect of the present application, an atomizer is provided, comprising:

[0047] Atomizing part 60, wherein an atomizing chamber 9 is provided in the atomizing part 60;

[0048] The mounting portion 61 is located at one side of the atomizing portion 60. An oil injection cavity 10 is disposed in the mounting portion 61. The oil injection cavity 10 is connected to the atomizing cavity 9 through an oil injection channel.

[0049] The oil storage bottle 82 is detachably fixed to the mounting portion 61, and the oil outlet 820 of the oil storage bottle 82 is located in the oil filling cavity 10;

[0050] The valve stem 12 is arranged on the mounting portion 61. The first end of the valve stem 12 extends into the oil filling chamber 10 and is provided with a plug 16. The plug 16 is configured to be able to be pushed into the oil outlet 820 and seal the oil outlet 820 and to be able to be detached from the oil outlet 820. The second end of the valve stem 12 extends out of the mounting portion 61 and is provided with a push-pull structure 11.

[0051] In this embodiment, the atomizer has a separate oil storage bottle 82, and a certain amount of smoke oil can be stored in the oil storage bottle 82, thereby increasing the use time of the atomizer. Specifically, the main body of the atomizer in this embodiment is divided into an atomization part 60 and a mounting part 61, wherein the atomization part 60 is provided with components required for atomization such as an atomization chamber 9 and an atomization core. The mounting part 61 is arranged on the side of the atomization part 60 as a structure for mounting the oil storage bottle 82, and an oil filling chamber 10 is arranged in the mounting part 61. The oil filling chamber 10 is connected with the atomization chamber 9 through an oil filling channel, so that the smoke oil in the oil filling chamber 10 can enter the atomization chamber 9 through the oil filling channel. The oil storage bottle 82 is mounted on the mounting part 61 in a detachable manner, and the user can replace the new oil storage bottle 82 for use after the smoke oil in the oil storage bottle 82 is used up. The installation method of the oil storage bottle 82 and the mounting part 61 can be threaded connection or clamping, etc., which is not limited in this embodiment.

[0052] In order to facilitate the control of the oil in the oil storage bottle 82 entering the atomization chamber 9 through the oil injection channel, a valve stem 12 is provided on the mounting portion 61 in this embodiment. The first end of the valve stem 12 extends into the oil injection chamber 10 and is provided with a plug 16 capable of blocking the oil outlet 820 of the oil storage bottle 82. Specifically, in this embodiment, the valve stem 12 is slidably connected or threadedly connected to the mounting portion 61, so that the plug 16 can move linearly upward or downward relative to the oil outlet 820. When the valve stem 12 is slidably connected to the mounting portion 61 and is provided with a corresponding sealing structure, the push-pull structure 11 at the second end of the valve stem 12 can be used to push the plug 16 to enter the oil outlet 820 of the oil storage bottle 82 and seal the oil outlet 820, so that the oil in the oil storage bottle 82 will not enter the atomization chamber 9 through the oil injection channel. When oil filling is needed, the plug 16 can be pulled outward by the push-pull structure 11 to separate it from the oil outlet 820. At this time, the atomizer can be tilted to allow the oil in the oil storage bottle 82 to flow into the oil filling chamber 10 through the oil outlet 820 and then into the atomization chamber 9 through the oil filling channel.

[0053] When the valve stem 12 is threadedly connected to the mounting portion 61 , the plug 16 can be blocked from the oil outlet 820 or detached from the oil outlet 820 by rotating the valve stem 12 through the push-pull structure 11 .

[0054] In this embodiment, after the oil storage bottle 82 is installed on the mounting portion 61 of the atomizer, the oil in the oil storage bottle 82 can be injected into the atomization chamber 9 of the atomizer by operating the valve stem 12. The larger volume of the oil storage bottle 82 can accommodate more oil, thereby increasing the use time of the atomizer and facilitating the long-term use of the atomizer. In addition, the oil storage bottle 82 is configured to be a detachable structure, so that the user can replace the oil storage bottle 82 with a new one for use.

[0055] In order to prevent the smoke oil in the atomization chamber 9 from flowing into the oil filling chamber 10 during normal use, the inner bottom surface of the oil filling chamber 10 in this embodiment is higher than the inner bottom surface of the atomization chamber 9, so that there is a height difference between the inner bottom surface of the oil filling chamber 10 and the inner bottom surface of the atomizer, and the oil inlet of the atomization core located in the atomization chamber 9 is at least partially located in the height difference area, so that the smoke oil located in the height difference area can enter the atomization core through the oil inlet and be atomized, and at the same time, the smoke oil in the height difference area is not easy to enter the oil filling chamber 10. Further, the upper end surface of the oil outlet 820 is flush with the inner bottom surface of the oil filling chamber 10, so that the smoke oil in the oil filling chamber 10 can completely flow into the atomization chamber 9.

[0056] The oil injection channel is a channel structure connecting the oil injection chamber 10 and the atomization chamber 9. In one embodiment, the oil injection channel includes an oil outlet hole 101 provided on the oil injection chamber 10 and an oil inlet hole 90 provided on the atomization chamber 9. The oil inlet hole 90 and the oil outlet hole 101 are arranged opposite to each other, thereby forming an oil injection channel. In order to facilitate the smoke oil to enter the atomization chamber 9 from the oil inlet hole 90, the oil inlet hole 90 in this embodiment is arranged as an inwardly contracted structure. Specifically, the upper top surface and both side surfaces of the oil inlet hole 90 in this embodiment are contracted structures, and the lower bottom surface is a planar structure aligned with the oil outlet hole 101.

[0057] When the valve stem 12 moves in a linear push-pull manner, in order to facilitate the push-pull of the valve stem 12, the push-pull structure 11 in this embodiment includes a pressure head 110 and a pull ring 111, the pressure head 110 is fixedly arranged at the second end of the valve stem 12, and the pull ring 111 is hinged on the pressure head 110. Specifically, when in use, the pressure head 110 can be pushed to push the valve stem 12 to move, and the pull ring 111 can also be pulled to pull the valve stem 12 to move. In addition, after the pull ring 111 is provided, it is also convenient to buckle the pull ring 111 at a specific position to carry the atomizer or the electronic cigarette equipped with the atomizer.

[0058] In order to improve the sealing ability of the plug 16 to the oil outlet 820, a first sealing groove 15 is provided on the ring side of the plug 16 in this embodiment, and a first sealing ring is sleeved and fixed in the first sealing groove 15, and the first sealing ring is used to abut against the inner wall of the oil outlet 820. On this basis, in order to facilitate the plug 16 to enter the oil outlet 820, a conical introduction surface is provided on the lower ring side of the plug 16 in this embodiment, and the upper ring side of the plug 16 is a straight surface, so that the contact area between the plug 16 and the oil outlet 820 can be increased while facilitating entry into the oil outlet 820, thereby improving the sealing performance.

[0059] In one embodiment, a mounting hole is provided on the mounting portion 61, and the mounting hole is connected to the oil filling chamber 10. The valve stem 12 is slidably installed in the mounting hole. In order to avoid improving the sealing between the valve stem 12 and the mounting hole, a second sealing groove 14 is provided on the valve stem 12 located at the mounting hole in this embodiment. A second sealing ring 13 is sleeved and fixed in the second sealing groove 14, and the second sealing ring 13 is against the inner wall of the mounting hole.

[0060] It can be understood that the second sealing groove 14 can also be arranged in the mounting hole.

[0061] To prevent the valve stem 12 from escaping from the mounting hole, in this embodiment, the plug 16 is coaxial with the valve stem 12, and the diameter of the upper end surface of the plug 16 is larger than the diameter of the valve stem 12. The upper end surface of the plug 16 is abutted against the upper end surface of the oil filling chamber 10 to limit the maximum pull-out stroke of the valve stem 12.

[0062] In one installation method of the oil storage bottle 82, the lower end of the mounting portion 61 is provided with an internal thread, and the upper end of the oil storage bottle 82 is provided with an external thread, and the external thread is threadedly connected with the internal thread. On this basis, in order to prevent the oil storage bottle 82 from being damaged due to being screwed in too deep, a step structure is provided at the lower part of the mounting portion 61 in this embodiment, and a positioning flange is provided on the oil storage bottle 82 to abut against the end surface of the step structure to locate the axial position of the oil storage bottle 82 after installation.
