Description

Technical Field

[0001] The utility model relates to the technical field of atomization, in particular to an aerosol generating device. Background Art

[0002] Most of the current aerosol generating products, i.e., atomizing products, are disposable products, and a small number are products with replaceable atomizing cores. For disposable products, when the life cycle of the heating sheet in the atomizing core ends, the entire atomizing product is directly discarded, which greatly wastes resources and increases the user's usage cost. For products with replaceable atomizing cores, when the life cycle of the heating sheet in the atomizing core ends, the atomizing core can be replaced to continue using the product. That is, in order to replace the heating sheet, the entire atomizing core needs to be replaced, and other good and continuously usable parts in the atomizing core will be discarded together, which still causes a waste of resources and increases the user's usage cost.

[0036] In one embodiment, an aerosol generating device is provided. The aerosol generating device is provided with a mounting opening on a shell, and a detachable or movable mounting cover is installed on the mounting opening. The atomizer core can be disassembled and the heating body can be replaced separately by opening the mounting opening, without replacing the entire atomizer core assembly, thereby achieving accurate replacement of parts that are incomplete in function or have expired, avoiding the discarding of parts of the atomizer core that have other intact functions or can still be used, and causing no waste of resources, which can effectively reduce the user's usage cost.

[0037] Since the heating body can be replaced individually, users can replace the heating body with different resistance values ​​according to their own preferences to achieve heating atomization with different tastes.

[0038] The aerosol generating device is also provided with a lifting mechanism, which is a semi-manual and semi-automatic driving cabinet, and the user can manually drive the heating body to move upward relative to the installation port, and automatically drive the heating body to move downward relative to the installation port. The setting of the lifting mechanism allows the user to disassemble and assemble the heating body at a position close to the installation port, which is conducive to improving the replacement efficiency of the heating body and greatly facilitates the user to replace the heating body.

[0039] Please refer to Figures 1 to 5 The aerosol generating device of this embodiment mainly includes a housing 1, an atomizing core 2 and a lifting mechanism 3. The atomizing core 2 and the lifting mechanism 3 are installed in the housing 1, and part of the lifting mechanism 3 is exposed outside the housing 1. The user can manually drive the heating body close to the outer side of the housing 1 until the removal position through the exposed part of the lifting mechanism 3. The lifting mechanism 3 can also automatically drive the heating body to move to the inside of the housing 1 until the installation position. The lifting mechanism 3 can realize semi-manual and semi-automatic driving of the heating body to move, so as to facilitate the user to remove the heating body and quickly install the heating body.

[0040] The aerosol generating device may further include components such as a circuit board 4 and a battery 5. The circuit board 4 is electrically connected to the atomizer core 2, and is used to control the atomizer core 2 to start and stop heating.

[0042] In this embodiment, the shell 1 can be a flat structure, and an installation port 11 is provided on the flat side surface (the side with a larger area) of the shell 1. The flat side surface has a larger area, and a larger opening installation port 11 can be provided to ensure that the installation port 11 is larger than the heating body, so that the heating body can be replaced and disassembled through the installation port 11.

The mounting cover 12 is embedded in the shell 1. The mounting cover 12 does not protrude from the shell 1, which is more beautiful. The non-protruding mounting cover 12 will not be accidentally pushed open, which can improve the stability of the installation and fixation of the mounting cover 12.

[0046] The sunken step of the outer shell 1 can also be installed with sealing parts such as sealing rings. When the mounting cover 12 is installed on the sunken step, the sealing ring is squeezed between the mounting cover 12 and the outer shell 1, so as to achieve sealing of the mounting port 11 and prevent the air path in the outer shell 1 from leaking from the mounting port 11, so that the setting of the mounting port 11 will not affect the heating and atomization of the aerosol generating device.
