Abstract: A gas-liquid separation device includes a housing assembly, a separation assembly, a bottom end plate, an exhaust pipe, and a seal. A separation chamber is defined in the housing assembly. A bottom of the housing assembly has a through-opening. The separation assembly performs gas-liquid separation on a gas-liquid mixture. The bottom end plate is located at a bottom of the separation assembly. A liquid reservoir is defined by the bottom end plate and receives a liquid separated by the separation assembly. The exhaust pipe has an exhaust channel and a liquid discharge channel. The exhaust pipe passes through the through-opening to allow a gas separated by the separation assembly to flow through the exhaust channel. A flow diversion cavity is defined between the exhaust pipe and the bottom end plate, and is in communication with an outlet of the liquid reservoir and an inlet of the liquid discharge channel.

Abstract: A guide device for directing a gas through gas pressurizing device, includes at least one part-ring shaped guide member having a pair of opposite first end and second end defining a gap therebetween, a lip extending from the guide member, and at least one groove configured in the gas pressurizing device to receive the guide member. The guide device provides a smooth passage to gas flow through a gas pressurizing device by directing gas through the gas pressurizing device, so as to improve efficiency and performance of the gas pressurizing device and eliminate need of fasteners, holes or brackets. The guide device is easy to mount in a gas pressurizing device as compared to conventional baffle ring.

Abstract: The power unit includes: a substrate having a first side surface at a first side thereof; a tablet structure located at the first side of the substrate; and a power structure configured to be pressed against the first side surface by the tablet structure. The power unit uses the tablet structure to press the power structure against the first side surface of the substrate, thereby achieving a firm and reliable installation of the power structure on the substrate.

Abstract: An inverter power assembly includes: a mounting frame; a power module mounted on the mounting frame; and a capacitor electrically connected to the power module. The inverter power assembly has the power module mounted on the mounting frame and the capacitor electrically connected to the power module, which leads to a simple and compact structure and a reasonable arrangement for the entire inverter power assembly.

Abstract: A lighthouse includes a mast device and a lighting device mounted on the mast device. The lighthouse further includes a main body including a box body and a top cover, the top cover is arranged on a top of the box body, the top cover and the box body define a receiving chamber, and the top cover is movable or detachable relative to the box body to open or close the receiving chamber. The lighthouse is convenient for overhaul and maintenance, and improves the maintenance efficiency.

Abstract: An air exhausting mechanism for a mobile illuminating light tower includes a cooler, an air discharge hood, and a fan. The cooler and the air discharge hood are respectively disposed on two sides of a rear canopy panel. The cooler is mounted on a bottom plate, and is located on the inner side of the rear canopy panel. The air discharge hood is fixedly mounted on the outer side of the rear canopy panel. The cooler is provided with an air inlet and an air outlet. An air exhausting groove is formed in the rear canopy panel. The fan is disposed at the air inlet of the cooler. The air exhausting groove is opposite to the air outlet. The air discharge hood covers the air exhausting groove, and the bottom of the air discharge hood is open. The mobile illuminating light tower is safe and environmentally friendly.
