When an element is referred to as being "connected" to another element, it can be directly connected to the other element or can have a middle element in between.

[0038] In view of the technical defects in the prior art, the present embodiment provides an electronic cigarette, which comprises a cartridge A and a cigarette rod B for supplying power to the cartridge A. Figure 1 As shown in the figure, the electronic cigarette of the present embodiment comprises a cartridge A and a cigarette rod B for supplying power to the cartridge A.

[0039] As shown in the figure, the cartridge A of the present embodiment comprises a housing 100 and a sealing seat 600, the housing 100 has a plug-in interface 102, and the sealing seat 600 can be embedded in the housing 100 through the plug-in interface 102. After the sealing seat 600 is embedded in the housing 100, it maintains a relatively fixed state with the housing 100. Of course, if it is needed to pull out the sealing seat 600, it can be pulled out from the housing 100 by means of a disassembling tool or the like. Figure 2 In an example, the inner wall of the housing 100 forms a limiting step, and after the sealing seat 600 is inserted into the housing 100 through the plug-in interface 102, it abuts against the limiting step, thereby forming a relatively fixed state with the housing 100. In another example, the side portion of the sealing seat 600 can be provided with an elastic flange, so that the sealing seat 600 forms an interference fit with the inner wall of the housing 100, thereby forming a relatively fixed state with the housing 100. In yet another example, the side portion of the sealing seat 600 can be provided with a buckle, and the inner wall of the housing 100 is provided with a clamping groove matched with the buckle, so that when the sealing seat 600 is embedded in the housing 100, the buckle is clamped into the clamping groove, thereby forming a relatively fixed state with the housing 100.

[0040] Continuing to refer to the figure, the side surface of the sealing seat 600 opposite to the plug-in interface 102 and the inner wall of the housing 100 enclose an oil storage cavity 101. The sealing seat 600 is provided with a connecting hole 601 in communication with the oil storage cavity 101, and the connecting hole 601 is arranged opposite to the plug-in interface 102.

[0041] Figure 2 The cartridge A of the present embodiment further comprises an atomizing tube 310 and an atomizing core 400. As shown in the figure,

[0042] The cartridge A of the present embodiment further comprises an atomizing tube 310 and an atomizing core 400. As shown in the figure, Figure 2 ​As shown, the atomizing tube 310 is movably arranged in the connecting hole 601, and the atomizing core 400 is arranged in the atomizing tube 310. The atomizing tube 310 further has a storage cotton 500 arranged in the atomizing tube 310 and sleeved on the atomizing core 400. The atomizing tube 310 has an oil inlet hole 301, and the region of the atomizing tube 310 having the oil inlet hole 301 is located in the connecting hole 601, so that the oil inlet hole 301 is sealed by the hole wall of the connecting hole 601, that is, the oil inlet hole 301 is separated from the storage cavity 101, so that the tobacco tar in the storage cavity 101 cannot flow into the atomizing tube 310 through the oil inlet hole 301.

[0043] The cartridge A of the embodiment further includes a movable base 700. As shown, Figure 2 The movable base 700 is movably inserted into the insertion port 102 and is arranged apart from the sealing seat 600. The movable base 700 is connected to the end of the atomizing tube 310 facing the insertion port 102. The movable base 700 further has an electrode 900 arranged thereon, which is electrically connected to the atomizing core 400.

[0044] As shown, Figure 3 In the structure of the cartridge A of the embodiment, the movable base 700 can move in the direction close to the sealing seat 600 under the action of an external force until the movable base 700 abuts against the sealing seat 600. When the movable base 700 moves under the action of the external force, the atomizing tube 310 connected to the movable base 700 also moves relative to the sealing seat 600 under the pushing of the movable base 700, so that the oil inlet hole 301 is exposed to the sealing seat 600. In this way, the oil inlet hole 301 is in communication with the storage cavity 101, so that the tobacco tar in the storage cavity 101 can flow into the atomizing tube 310 through the oil inlet hole 301 and soak the atomizing core 400.

[0045] As can be seen, the cartridge A of the embodiment can be in the state of separating the tobacco tar and the atomizing core 400 in the transportation state, so that the tobacco tar in the storage cavity 101 cannot leak out even if the external air pressure changes greatly. When a user receives the cartridge A of the embodiment, the user can press the movable base 700 to make the tobacco tar contact the atomizing core 400, so that the process of contacting the tobacco tar and the atomizing core 400 is relatively convenient.

[0046] As shown, Figure 2 The shell 100 has a suction nozzle 200 connected to the outer wall thereof, and the shell 100 has a connecting tube 140 arranged in the inner wall thereof and in the storage cavity 101. The connecting tube 140 is in communication with the suction nozzle 200, and the tube opening of the connecting tube 140 is arranged opposite to the connecting hole 601. The end of the atomizing tube 310 away from the insertion port 102 is movably nested with the connecting tube 140, so that the atomizing tube 310 can move relative to the sealing seat 600 under the pushing of the movable base 700.

[0047] Further, as shown, Figure 2As shown, the cartridge A of the present embodiment further comprises a sealing member 320, which is sleeved on one end of the atomizing tube 310 away from the plug-in interface 102 and movably embedded in the connecting tube 140, so as to reduce the leakage of the tobacco tar in the oil storage cavity 101 from the connection between the atomizing tube 310 and the connecting tube 140.

[0048] With reference to Figure 2 and Figure 3 As shown, in some embodiments, the inner wall of the shell 100 between the sealing seat 600 and the plug-in interface 102 is formed with a first clamping groove 110 and a second clamping groove 120. The first clamping groove 110 and the second clamping groove 120 are arranged along the axial direction of the shell 100, and the second clamping groove 120 is closer to the plug-in interface 102 than the first clamping groove 110. The side portion of the movable base 700 is provided with a clamping member 721, which is clamped in the second clamping groove 120.

[0049] In combination with Figure 3 As shown, under the action of an external force, during the movement of the movable base 700 in the direction close to the sealing seat 600, the clamping member 721 is clamped into the first clamping groove 110 after being disengaged from the second clamping groove 120, so as to further prevent the movable base 700 from being disengaged from the shell 100.

[0050] Further, in combination with Figure 4 and Figure 5 As shown, the inner wall of the shell 100 is further formed with a guide through groove 130, which is located between the first clamping groove 110 and the second clamping groove 120 and communicates the first clamping groove 110 and the second clamping groove 120. The guide through groove 130 is used to guide the clamping member 721 during the process of being clamped into the first clamping groove 110 after being disengaged from the second clamping groove 120. Exemplarily, one side groove wall of the guide through groove 130 is a convex curved surface, and the other side groove wall of the guide through groove 130 is a concave curved surface, and the curvatures of the convex curved surface and the concave curved surface are the same. The design of the guide through groove 130 of this example can exert a certain degree of resistance on the clamping member 721 when the clamping member 721 is about to move, so as to prevent the user from mistakenly pushing the movable base 700.

[0051] With reference to Figure 2 As shown, in some embodiments, the movable base 700 comprises a first base 710 and a second base 720. The first base 710 is movably embedded in the shell 100 and is arranged in a spaced manner with the side of the sealing seat 600 facing the plug-in interface 102, and the first base 710 is connected with the end of the atomizing tube 310 facing the plug-in interface 102. A part of the second base 720 is movably plugged into the plug-in interface 102 and connected with the side of the first base 710 away from the sealing seat 600.

[0052] According to actual design needs, the buckle 721 can be arranged on the side of the first base 710 or the side of the second base 720.

[0053] Further, in order to reduce the leakage of the condensed liquid, the second base 720 is formed with a containing groove on the side facing the first base 710, and the containing groove is arranged with an oil absorbing cotton 800.

[0054] The above only describes some or preferred embodiments of the present application, neither the text nor the drawings can limit the scope of protection of the present application, any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields are included in the scope of protection of the present application.
