Abstract: An atomizer includes: a liquid storage housing, a liquid storage cavity being formed in the liquid storage housing; a first atomization base disposed at least partially in the liquid storage housing; a second atomization base disposed in the liquid storage housing, an atomization cavity being formed between the second atomization base and the first atomization base; and an atomization core at least partially disposed in the atomization cavity. A cavity bottom surface of the liquid storage cavity comprises at least one liquid guiding surface extending axially along the atomization core. The at least one liquid guiding surface has a structure with a high middle and two low ends.

Abstract: An atomization assembly includes: a main housing having an atomization cavity and a medium storage cavity circumferentially surrounding the atomization cavity; and a heating unit including a liquid guide tube and a heating element, a first part of the liquid guide tube being accommodated in the atomization cavity, a second part of the liquid guide tube extending into the medium storage cavity, the heating element being wound outside the first part of the liquid guide tube accommodated in the atomization cavity. The liquid guide tube conducts heat generated by the heating element to the medium storage cavity.

Abstract: A porous bioceramic-modified heating structure includes: a substrate; and a porous bioceramic layer located on a surface of the substrate. The porous bioceramic layer has micro-nano protrusions. A base material of the porous bioceramic layer is calcium phosphate salt. In an embodiment, a thickness of the porous bioceramic layer ranges from 10 ?m to 500 ?m.

Abstract: A charging apparatus, includes a charging pile and a charging gun. The charging pile is provided with a slot, and a reader is provided in the slot; a charging gun is connected to the charging pile, the charging gun includes a gun head, the gun head is used for plugging into a slot, and the charging gun is provided with at least two electronic tags; in a state where the gun head is just plugged into the slot, the reader just identifies an electronic tag, and in a state where the gun head is completely plugged into the slot, the reader just identifies another electronic tag; therefore, the charging apparatus can distinguish whether the charging gun corresponds to returning a gun and whether the charging gun is returned in place.

Abstract: A gun-returning detection method is applied to a charging pile, the charging pile comprises a charging gun and a slot for accommodating the charging gun, the charging gun is provided with an electronic tag, and the slot is provided with a radio frequency identification module. The method firstly acquires tag information about the charging gun inserted into the slot, and then judges whether the tag information matches with the verification information about the slot, so as to obtain and output a final gun-returning detection result; the gun-returning detection method provided in the present application can realize one-to-one identification of a charging gun and a slot, and detect whether the charging gun is homed to the original slot which is beneficial to the management of the charging gun and the charging pile.

Abstract: An atomization core includes: a support member having a liquid guiding channel and a liquid guiding hole, the liquid guiding channel running through two ends of the support member in an axial direction of the support member, the liquid guiding hole running through a side wall of the liquid guiding channel in a radial direction of the support member; a liquid guiding core sleeved on an outer periphery of the support member, an aerosol-forming medium in the liquid guiding channel being guidable to the liquid guiding core through the liquid guiding hole; and a heating mesh arranged on an outer periphery of the liquid guiding core for heating and atomizing the aerosol-forming medium

Abstract: A heating element for heating and atomizing an aerosol generation substrate includes: a support tube; and a conduction layer arranged on an outer side of the support tube and in communication with the support tube, the conduction layer having an integrally braided structure. In an embodiment, a thickness of the conduction layer is greater than or equal to 0.1 mm and less than or equal to 3 mm.
