DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

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 in the figure) 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 and a movable member 12 rotatably arranged 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 stagger the movable member 12 and the liquid injection hole 112 to expose or close the liquid injection hole 112. When the movable member 12 is staggered with 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 of the embodiments, the cartridge housing includes a housing 11 and a sealing member. The housing 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 housing 11, the sealing member is installed at one end of the housing 11 for sealing the liquid storage cavity 111. A vent tube 13 is formed on the top of the housing 11 extending downward along the axial direction of the housing 11. The upper end of the vent tube 13 passes through the upper end surface of the housing 11, the upper end opening of the vent tube 13 is provided with 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 is provided with a smoke outlet channel 131. When the user performs a suction operation, the smoke generated by the atomization of the cigarette 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 of the embodiments, as shown in FIGS. 5 to 11, a liquid injection hole 112 is provided on the sealing member. The movable member 12 is connected to the sealing member and is located on one side of the liquid injection hole 112. When the user performs the liquid injection operation, the liquid storage assembly 10 is adjusted to the state where the liquid injection hole 112 is located above, firstly; and then, the movable member 12 is rotated, so that the movable member 12 and the liquid injection hole 112 are staggered to expose the liquid injection hole 112; finally, a liquid injection mechanism (for example, a liquid injection needle) is used to inject 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, the rotating movable member 12 can make the main body 121 and the liquid injection hole 112 stagger each other to expose the liquid injection hole 112, so that liquid can be injected into the liquid storage cavity 111 through the liquid injection hole 112.

In a specific embodiment, the movable member 12 also includes a rotating shaft 122 protruding from one end of the main body 121 and a limiting member 123 disposed at the other 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.

A groove 142 is partially recessed on one end surface of the sealing member. The side wall of the groove 142 is provided with an abutting edge 145, the liquid injection hole 112 is defined 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 part of the outer peripheral wall of the main body 121 is attached to 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 structure, the main body 121 is an arc structure matched with the abutting edge 145 to facilitate the rotation of the movable member 12.

In a specific embodiment, the sealing member is also provided with an exhaust hole 144 communicating with the liquid storage cavity 111. When the rotating movable member 12 to the main body 121 closes the liquid injection hole 112, the 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 exhaust hole 144. When the rotating movable member 12 to the main body 121 and the liquid injection hole 112 are staggered, the liquid injection hole 112 is exposed, and the exhaust hole 144 is also exposed. In the process of injecting liquid into the liquid storage cavity 111 through the liquid injection hole 112, the excess air in the liquid storage cavity 111 circulates to the outside of the electronic cigarette through the 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 base 14 and a connecting member 15. The base 14 is arranged in the lower end of the housing 11, the connecting member 15 is sleeved on the outside of the base 14 and tightly resists the inner wall of the housing 11, thereby achieving a sealing effect. Specifically, the outer peripheral wall of the base 14 is recessed inwardly along the radial direction of the base 14 to form an annular groove 141. One end of the connecting member 15 is arranged in the annular groove 141 so as to realize the connection between the connecting member 15 and the base 14. The groove 142 and the abutting edge 145 are arranged on the base 14. The space between the end face of the connecting member 15 away from the liquid storage cavity 111 and the abutting edge 145 forms a receiving groove 157. The movable member 12 is at least partially received in the receiving groove 157. The base 14 is further provided with an abutting block 146 on opposite sides of the abutting edge 145. When the movable member 12 is completely contained in the receiving groove 157, the upper end surface of the main body 121 abuts the abutting block 146 to prevent the movable member 12 from being easily rotated.

In one of the embodiments, the connecting member 15 is provided with a liquid intake hole 153 corresponding to the liquid injection hole 112 and a vent hole 154 corresponding to the exhaust hole 144.

The flange 156 is tightly attached to the inner wall of the housing 11 to enhance the sealing performance between the connecting member 15 and the housing 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 housing 11 is enhanced to prevent the leakage of e-liquid in the liquid storage cavity 111. 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 one end of the main body 121 away from the liquid injection hole 112, which facilitates the rotation of the movable member 12 through it, and the movable member 12 can be rotated by holding and rotating the rotating button 1211.
