Abstract: Embodiments of the present disclosure provide an electronic device control method and apparatus, an electronic device, and a storage medium. The electronic device control method includes: selecting a target mode from optional modes of a fan of an electronic device, the optional modes including a cleaning mode and a heat dissipation mode, where in the cleaning mode, the fan provides at least two different air strengths, and in the heat dissipation mode, the fan provides a single air strength when a heat dissipation level is not switched; generating a control signal based on the target mode; and controlling, based on the control signal, the fan to provide an air strength.

Abstract: A connector, a connector assembly, a liquid cooled plate, and a liquid cooled server, where the connector includes a first connector body, a ball body, and a mesh baffle, where an annular protrusion part is provided inside the first connector body and forms an annular through-hole, and the ball body is disposed in a hollow inner cavity and is limited by the annular protrusion part and the mesh baffle; when fluid enters from a first inlet, the ball body is away from the annular through-hole to form an opened passage, and when the fluid enters from a first outlet, the ball body blocks the annular through-hole to form a closed passage. The connector assembly includes a first connector and a second connector, the first connector adopts the connector above, the second connector includes a cut elastic retaining ring for dividing the elastic retaining ring into a plurality of blades.

Abstract: A concrete variable cross-section prefabricated square pile comprises pile bodies of large cross-section sections and small cross-section sections alternately arranged along a longitudinal direction. Lateral transition surfaces are formed between side surfaces of the large cross-section sections and adjacent small cross-section sections; at least part of the lateral transition surfaces have a front edge and/or a rear edge that are offset from a vertical direction in a lateral projection, and a vertical projection of an intersection line between the lateral transition surface and a first horizontal plane is located outside a vertical projection of an intersection line between the lateral transition surface and a second horizontal plane; the first horizontal plane is a horizontal plane located above in any two horizontal planes, and the second horizontal plane is a horizontal plane located below in any two horizontal planes.

Abstract: A prefabricated wall for a prefabricated building includes a concrete body and a rigid framework arranged inside the poured concrete body, the rigid framework comprises n longitudinally extending vertical rebars, with n being an integer greater than or equal to three; an upper end face and a lower end face of the prefabricated wall are formed with m mechanical connection portions at positions sharing the same axes as the vertical rebars, with m being an integer less than or equal to 2n; and the mechanical connection portions are all formed at end portions of the vertical rebars. An assembly structure for a prefabricated building is further provided. The assembly structure is formed by filling an assembly gap with an on-site poured layer after rebars are firmly connected at an overhead region between an upper-layer wall, a lower-layer wall and a floor slab by means of fastening components.
