A self-regulating temperature float-type fuel tank, relating to the field of engine fuel tank technology, includes a tank body with an oil inlet at the top and an oil outlet at the bottom. Inside the tank body are a heater, a temperature sensor, and a cooling core. The heater and cooling core are horizontally positioned above the oil outlet, and the temperature sensor is positioned close to the oil outlet. The cooling core includes several cooling pipes and several clamping plates, which are vertically spaced. The cooling pipes pass horizontally through the clamping plates, and their two ends are connected to the tank body. Water inlets and outlets, communicating with the interior of the cooling pipes, are installed on the side walls of the tank body. The water inlets are connected to a water pump. This application can change the original cooling method, improve cooling efficiency, reduce engine output loss, adjust engine power output in a timely manner, and improve user experience.

The intelligent flashlight comprises a flashlight body assembly, a lamp cap assembly, a lamp tail assembly and a battery assembly, a PCB is arranged in the lamp tail assembly, a gyroscope sensor and an acceleration sensor are arranged on the PCB, the gyroscope sensor is used for detecting the swing amplitude and position of the flashlight, and the acceleration sensor is used for detecting the swing amplitude and position of the flashlight. The acceleration sensor is used for detecting the height position and the moving state of the flashlight, and the PCB automatically adjusts the brightness change or the on-off state of the lamp holder assembly according to detection information fed back by the gyroscope sensor and the acceleration sensor. The flashlight is simple in structure and convenient and fast to use, the gyroscope sensor and the acceleration sensor are additionally arranged on the PCB, data information detected by the gyroscope sensor and the acceleration sensor is transmitted back to a chip on the PCB for data analysis, and therefore the motion state and direction of the flashlight are judged. Therefore, the light intensity or the power-off stop state is automatically adjusted, the light is prevented from being focused at one point for a long time, high-temperature heating is reduced, and the service life of the flashlight is prolonged.

The invention discloses a two-stage conversion asymmetric bipolar pulse micro-arc oxidation power supply, which comprises a first-stage conversion module, a second-stage conversion module and a full-bridge inversion module, and is characterized in that the first-stage conversion module is connected with the second-stage conversion module, and the second-stage conversion module is connected with the full-bridge inversion module, the first-stage conversion module is used for converting input alternating current into high-voltage direct current, the second-stage conversion module is used for converting the high-voltage direct current into low-voltage direct current, and the full-bridge inversion module is used for converting the low-voltage direct current into bipolar pulses.
