DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present application will now be described in detail with reference to the drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present application in a schematic manner, so it only shows the structure related to the present application.
As shown in FIGs. 1 to 4 and 10, the present disclosure provides an electronic cigarette, the electronic cigarette includes a cartridge 100 and a power supply device (not shown) electrically connected to the cartridge 100, wherein the cartridge 100 includes a liquid storage assembly 10 and an atomizing head 20. In use, the e-liquid in the liquid storage assembly 10 enters the atomizing head 20, the power supply device supplies power to the atomizing head 20, and the atomizing head 20 atomizes the e-liquid to generate smoke for the user to inhale.
The liquid storage assembly 10 includes a cartridge housing having a liquid storage cavity 111 therein and a movable member 12 rotatably provided on the cartridge housing. The cartridge housing is provided with a liquid injection hole 112 communicating with the liquid storage cavity 111. The movable member 12 is located on one side of the liquid injection hole 112. Rotating the movable member 12 can enable the movable member 12 to be staggered from the liquid injection hole 112 so as to expose the liquid injection hole 112, or enable the movable member 12 to close the liquid injection hole 112. When the movable member 12 is staggered from the liquid injection hole 112 to expose the liquid injection hole 112, the user can inject e-liquid into the liquid storage cavity 111 through the liquid injection hole 112. When the movable member 12 closes the liquid injection hole 112, the liquid storage cavity 111 communicating with the liquid injection hole 112 is also closed, the e-liquid in the liquid storage cavity 111 cannot flow out, and the user cannot perform the liquid injection operation.
In one embodiment, the cartridge housing includes an outer casing 11 and a sealing member. The outer casing 11 is generally a hollow cylindrical structure with an opening at the lower end. The liquid storage cavity 111 is formed by the inner cavity of the outer casing 11. The sealing member is installed at one end of the outer casing 11 for sealing the liquid storage cavity 111. A vent tube 13 is formed on the top of the outer casing 11 by extending downward along the axial direction of the outer casing 11. The upper end of the vent tube 13 passes through the upper end surface of the outer casing 11, and the opening at the upper end of the vent tube 13 forms as a smoke outlet opening 113. The lower end of the vent tube 13 is connected with the atomizing head 20. The inner cavity of the vent tube 13 forms as a smoke outlet channel 131. When the user performs a suction operation, the smoke generated by the atomization of the e-liquid by the atomizing head 20 passes through the smoke outlet channel 131 and then enters the user's mouth through the smoke outlet opening 113.
In one embodiment, as shown in FIGs. 5 to 11, the liquid injection hole 112 is provided on the sealing member. The movable member 12 is connected to the sealing member and located on one side of the liquid injection hole 112. When the user performs the liquid injection operation, the liquid storage assembly 10 is firstly adjusted to the state where the liquid injection hole 112 is located on the top, and then the movable member 12 is rotated, so that the movable member 12 is staggered from the liquid injection hole 112 to expose the liquid injection hole 112; and finally, a liquid injection tool (for example, a liquid injection needle) is used to inject e-liquid into the liquid storage cavity 111 through the liquid injection hole 112.
The movable member 12 includes a main body 121. Rotating the movable member 12 can make the main body 121 cover the liquid injection hole 112 so as to close the liquid injection hole 112. Or, rotating the movable member 12 can make the main body 121 and the liquid injection hole 112 stagger from each other to expose the liquid injection hole 112, so that e-liquid can be injected into the liquid storage cavity 111 through the liquid injection hole 112.
In a specific embodiment, the movable member 12 further includes a rotating shaft 122 protruding from the main body 121 and a limiting member 123 disposed at one end of the rotating shaft 122 relative to the main body 121. The sealing member is provided with a mating hole 155. The rotating shaft 122 is rotatably installed in the mating hole 155. The limiting member 123 is sleeved on one end of the rotating shaft 122 away from the main body 121 and abuts against the mating hole 155 to prevent the movable member 12 from falling off the sealing member.
One end surface of the sealing member is partially recessed to form a groove 142. The side wall of the groove 142 is provided with an abutting edge 145. The liquid injection hole 112 is provided on the bottom wall of the groove 142. The main body 121 is at least partially received in the groove 142. When the movable member 12 is rotated to make the main body 121 cover and close the liquid injection hole 112, a portion of the outer peripheral wall of the main body 121 is in contact with the abutting edge 145 to realize seamless connection between the sealing member and the movable member 12. In this embodiment, the abutting edge 145 has an arc-shaped structure, and the outer peripheral wall of the main body 121 has an arc-shaped structure matched with the abutting edge 145 to facilitate the rotation of the movable member 12.
In a specific embodiment, the sealing member is further provided with an air exhaust hole 144 communicating with the liquid storage cavity 111. When the movable member 12 is rotated until the main body 121 closes the liquid injection hole 112, the air exhaust hole 144 is also closed by the main body 121, and the e-liquid in the liquid storage cavity 111 will not leak through the air exhaust hole 144. When the movable member 12 is rotated until the main body 121 and the liquid injection hole 112 are staggered from each other, the liquid injection hole 112 is exposed, and the air exhaust hole 144 is also exposed, In the process of injecting e-liquid into the liquid storage cavity 111 through the liquid injection hole 112, the unwanted air in the liquid storage cavity 111 circulates to the outside of the electronic cigarette through the air exhaust hole 144 to prevent excessive pressure in the liquid storage cavity 111 from causing difficulty in liquid injection.
In a specific embodiment, the sealing member includes a bottom base 14 and a connecting member 15. The bottom base 14 is arranged in the lower end of the outer casing 11, and the connecting member 15 is sleeved on the outside of the bottom base 14 and tightly resists the inner wall of the outer casing 11 to achieve a sealing effect. Specifically, the outer peripheral wall of the bottom base 14 is recessed inwardly along the radial direction of the bottom base 14 to form an annular groove 141, and one end of the connecting member 15 is disposed in the annular groove 141, so as to realize the connection between the connecting member 15 and the bottom base 14. The groove 142 and the abutting edge 145 are provided on the bottom base 14. The space between one end surface of the connecting member 15 away from the liquid storage cavity 111 and the abutting edge 145 forms a containing groove 157. The movable member 12 is at least partially received in the containing groove 157. The bottom base 14 is further provided with abutting blocks 146 on opposite ends of the abutting edge 145. When the movable member 12 is completely received in the containing groove 157, the upper end surface of the main body 121 abuts against the abutting blocks 146 to prevent the movable member 12 from being easily rotated.
In one embodiment, the connecting member 15 is provided with a liquid intake hole 153 corresponding to the liquid injection hole 112 and an air vent hole 154 corresponding to the air exhaust hole 144. The mating hole 155 is provided in the connecting member 15. The bottom wall of the groove 142 is provided with an engaging hole 143 corresponding to the mating hole 155. The liquid intake hole 153 is in communication with the liquid injection hole 112. The air vent hole 154 is in communication with the air exhaust hole 144. The engaging hole 143 is in communication with the mating hole 155. The rotating shaft 122 passes through the mating hole 155 and then is inserted into the engaging hole 143. The limiting member 123 is sleeved on one end of the rotating shaft 122 and received in the engaging hole 143.
It can be understood that, in other embodiments not shown, the connecting member 15 and the bottom base 14 may also be connected together by plug-in connection, threaded connection, or magnetic connection. A flange 156 protrudes from the outer peripheral wall of the connecting member 15. The flange 156 is tightly contacted with the inner wall of the outer casing 11 to enhance the sealing performance between the connecting member 15 and the outer casing 11. The connecting member 15 is made of a sealing material such as silicone or rubber. On the one hand, the sealing performance between the connecting member 15 and the outer casing 11 is enhanced to prevent the leakage of the e-liquid in the liquid storage cavity 111, and on the other hand, the tightness of the connection between the connecting member 15 and the movable member 12 is enhanced to prevent the e-liquid in the liquid storage cavity 111 from leaking out through the liquid injection hole 112.
In addition, a rotating button 1211 protrudes from the end surface of the main body 121 away from the liquid injection hole 112 for facilitating the rotation of the movable member 12 through the rotating button 1211, so that the movable member 12 can be rotated by holding and rotating the rotating button 1211.
As shown in FIGs. 2, 3 and 10, when the liquid injection hole 112 needs to be opened for liquid injection, the movable member 12 is rotated, and the movable member 12 rotates around the rotating shaft 122.
