A cartridge includes a cartridge body, a base provided at one end of the cartridge body, and an atomizing head received in the cartridge body. The atomizing head includes a heating structure. The heating structure has two pins. A first pressing member and a second pressing member are installed on the base. The first pressing member presses and fixes one of the pins on the base and is electrically connected to the pin. The second pressing member presses and fixes the other pin on the base and is electrically connected to the other pin. The two pins of the heating structure are respectively pressed and fixed by the first pressing member and the second pressing member. It is convenient for the user to replace the heating structure, the operation is simple and convenient, the connection stability is strong, and the user experience is improved.

Cartridge and electronic cigarette

A power supply device includes a battery housing having a receiving chamber and a battery assembly installed in the receiving chamber. The battery assembly comprises a circuit board and a USB interface connected to the circuit board. The circuit board is protrudingly provided with a retaining protrusion. The retaining protrusion elastically abuts against and is slidable along an inner wall of the receiving chamber along an axial direction of the battery housing. The inner wall of the receiving chamber is provided with a retaining groove corresponding to the retaining protrusion. The retaining groove is provided on the sliding path of the retaining protrusion. The battery housing is further provided with a USB slot. When the retaining protrusion slides to be aligned with the retaining groove, the retaining protrusion is engaged into the retaining groove, and the USB interface is inserted into the USB slot simultaneously.

Power supply device, electronic cigarette, and assembly method

A battery housing includes a first casing and a second casing. A side wall of the first casing is provided with a limiting groove along an axial direction of the first casing. A guiding rib is protrudingly provided on the outer wall of the first casing along the axial direction of the first casing. An inner wall of the second casing is protrudingly provided with a limiting protrusion corresponding to the limiting groove along an axial direction of the second casing. A side wall of the second casing is provided with a guiding groove corresponding to the guiding rib along the axial direction of the second casing. When the second casing is sleeved on the outside of the first casing, the limiting protrusion is engaged in the limiting groove, and the guiding rib is engaged in the guiding groove.
