An opening is provided at the upper end of the partition plate. The opening is used for communicating the liquid storage cavity with the ventilation cavity. The liquid storage cavity is located directly below the communicating hole. The ventilation cavity is located away from the underside of the communicating hole.

An atomizer includes a liquid storage member and an atomizing assembly. A liquid storage chamber used to store an aerosol-forming substrate is provided in the liquid storage member. The atomizing assembly is slidably connected to the liquid storage member, and includes a heating structure. The atomizing assembly is provided with a liquid inlet. A sealing member is installed in the liquid inlet. An abutting rod is provided within the liquid storage member and is fixed relative to the liquid storage member. The abutting rod is connected to the sealing member. Sliding the atomizing assembly relative to the liquid storage member enables the atomizing assembly to move between a first position and a second position. When the atomizing assembly is in the first position, the sealing member closes the liquid inlet. When the atomizing assembly is in the second position, the sealing member is separated from the liquid inlet.

The present invention relates to an aerosol generation apparatus. The aerosol generation apparatus includes a power source circuit, a switch circuit, a control circuit and a detection circuit, wherein an output end of the power source circuit is connected to a first input end of the control circuit; an output end of the detection circuit is connected to a second input end of the control circuit, and the detection circuit is used for generating an electrical signal according to a detected connection state of an atomizer and outputting the electrical signal to the control circuit; and an output end of the switch circuit is connected to a third input end of the control circuit for transmitting a switch signal to the control circuit, and the control circuit controls the operating state of the atomizer according to the switch signal. The present invention can improve the usage experience of a user.

A cartridge includes a cartridge housing having a liquid storage cavity, and a sealing member for sealing the liquid storage cavity, and a first electrode and a second electrode mounted on the sealing member. A first blind hole and a second blind hole are respectively disposed on the end face of the sealing member away from the liquid storage cavity. The liquid injection needle pierces the sealing member through the wall of at least one of the first blind hole and the second blind hole and communicates with the liquid storage cavity to inject liquid into the liquid storage cavity. After the liquid injection is completed, the liquid injection needle is pulled out, and the sealing member is self-sealed at the pierced position. The first blind hole is blocked by the first electrode while the second blind hole is blocked by the second electrode.

Disclosed are a cartridge and an electronic cigarette having the cartridge. The cartridge includes a liquid storage cavity, an atomizing cavity, a liquid suction member, a liquid outlet, a smoke outlet, and an air inlet opening. Before the cartridge is used, the liquid outlet is in a closed state, such that e-liquid in the liquid storage cavity is isolated from the liquid suction member. When the cartridge is used, the liquid outlet is in an open state, such that the e-liquid in the liquid storage cavity flows out through the liquid outlet. The atomizing cavity is provided with an opening, and the size of the heating member matches the size of the opening; and when the cartridge is used, the heating member extends into the atomizing cavity through the opening and comes into contact with the liquid suction member or stays a preset distance away from the liquid suction member.

An atomizer includes a liquid storage member, an air guiding member and a bottom seat arranged between the liquid storage member and the air guiding member, wherein an atomizing chamber is provided in the atomizer, an air guiding groove in communication with the atomizing chamber is provided on the liquid storage member, and an air inlet channel in communication with the air guiding groove is provided on the air guiding member.

An atomizing assembly for an atomizer is provided. The atomizer includes a liquid storage member and the atomizing assembly, the liquid storage member is used to store an aerosol-forming substrate. The atomizing assembly includes a heating assembly and a sealing member. The sealing member is provided with a receiving groove, the heating assembly includes a liquid absorbing member and a heating member, the liquid absorbing member is installed in the receiving groove. The liquid absorbing member includes a liquid absorbing surface used for contacting the aerosol-forming substrate and an atomizing surface on which the heating member is arranged, a protrusion is provided on the liquid absorbing surface, a space defined by the receiving groove, the liquid absorbing surface and the protrusion constitutes a liquid inlet groove. The aerosol-forming substrate is conducted by the liquid absorbing member from the liquid absorbing surface to the atomizing surface.

A cartridge includes a cartridge shell, and a movable structure and an atomizing structure received in the cartridge shell. The cartridge shell is provided with a vent hole. The movable structure includes an isolation guiding tube received in the cartridge shell and a movable tube at least partially disposed in the isolation guiding tube. The movable tube includes an operating portion and a shielding portion connected to a lower end of the operating portion. The operating portion is located in the isolation guiding tube and one end of the operating portion extends out from the vent hole. The atomizing structure is provided with a liquid inlet hole. The shielding portion is movably sleeved on the atomizing structure to shield or expose the liquid inlet hole, to cause the liquid inlet hole to be isolated from or in communication with the liquid storage chamber.

A cartridge includes a cartridge housing, an atomizing head, and a sealing member. A liquid storage cavity for storing e-liquid is formed inside the cartridge housing. The atomizing head is located at one end of the cartridge housing, and the sealing member is located at the other end of the cartridge housing opposite to the atomizing head. The atomizing head is in communication with the liquid storage cavity and the outside. When a liquid injection needle is used to inject liquid into the cartridge, the liquid injection needle pierces the sealing member and extends into the cartridge housing to inject e-liquid into the liquid storage cavity. The air in the liquid storage cavity is discharged out through the end of the cartridge housing with the atomizing head. After the liquid injection needle is pulled out, the sealing member will form a self-sealing at the pierced position.
