Abstract: The present application relates to a silicone oil-based immersion coolant for an electronic component. The silicone oil-based immersion coolant for an electronic component includes a base oil and an additive. The base oil includes a low-viscosity silicone oil. The additive includes a silicone oil diluent and a thermally conductive inorganic filler. The viscosity of the low-viscosity silicone oil is less than or equal to 1000 cSt. The thermally conductive inorganic filler is an insulating filler. Based on the mass of the immersion coolant, a mass percentage content of the base oil is in a range from 70% to 85%, a mass percentage content of the silicone oil diluent is in a range from 10% to 20%, and a mass percentage content of the thermally conductive inorganic filler is in a range from 5% to 10%.

Abstract: A humidifier includes a base including a water reservoir cavity, a trigger switch provided at the base, and a trigger component located in the water reservoir cavity. An outer side of the trigger switch is provided with a waterproof protective cover. The trigger component is configured to, in response to a water level in the water reservoir cavity rising to a predetermined water level line, push the waterproof protective cover to trigger the trigger switch to control the humidifier to work. A wall thickness the waterproof protective cover at a position where the waterproof protective cover contacts the trigger component is less than a wall thickness of the waterproof protective cover at other positions of the waterproof protective cover.

Abstract: water ripple lamp includes: a housing assembly, a first water ripple light-transmitting plate, a water ripple light-transmitting tube assembly and a limiting assembly. The housing assembly is configured to define at least one light outlet. The first water ripple light-transmitting plate is configured to cover the at least one light outlet. The water ripple light-transmitting tube assembly is arranged inside the housing assembly. The water ripple light-transmitting tube assembly is configured to be rotatable. The water ripple light-transmitting tube assembly includes: a water ripple light-transmitting tube and an outer ring fixed to the water ripple light-transmitting tube. The limiting assembly includes a retaining ring and a bearing structure. The bearing structure is fixed to the retaining ring. The bearing structure includes a bearing. The bearing abuts against the outer ring, and is rollable relative to the outer ring.

Abstract: A serial peripheral interface (SPI)-based data transmission method, including sending, by a first device, a first query request to a second device through a universal asynchronous receiver/transmitter (UART) interface, where the first query request queries the second device for an SPI mode supported by the second device, sending, by the first device, in response to the first device determining, according to a first query response returned by the second device, that the second device supports an SPI master mode, an SPI connection establishment request to the second device, where the SPI connection establishment request causes the second device to initiate establishment of an SPI connection to the first device, and performing, by the first device, through the SPI, and after the first device establishes the SPI connection to the second device, at least one of receiving data sent by the second device, or sending data to the second device.
