This utility model discloses a water-cooled pressure cooking appliance, including a pot body and a pot lid. The pot lid is provided with a water-cooling cavity. The water-cooled pressure cooking appliance also includes a water tank detachably installed on the pot body or the pot lid. The bottom wall of the water tank is provided with a connecting port, which communicates with the water-cooling cavity. When the water tank is removed, coolant can be added to the water tank through the connecting port. The water tank is also provided with a baffle wall protruding towards the inside of the water tank, surrounding the outer periphery of the connecting port. When the water tank is inverted, as the user adds coolant to the water tank, the liquid level in the water tank gradually rises until it contacts the baffle wall. At this time, the coolant and the baffle wall form a water seal, and some air is trapped in the cavity area. The coolant does not completely fill the cavity area, thus strictly controlling the amount of coolant in the water tank. Furthermore, when the heated coolant flows back into the water tank, the risk of coolant overflowing from the vent is reduced because the coolant is far from the vent.

The application relates to the technical field of laser detection, and discloses a laser detection tool and detection method for multi-wire cutting workpieces, which comprises an operation table and a wire rack, the wire rack is fixed at the top of the operation table, one side of the top of the operation table is fixed with a displacement system, the top of the wire rack is fixed with an auxiliary tool, a reserved adjusting cavity is arranged at the middle position of a horizontal part of the auxiliary tool, a water storage cavity is arranged at the side of the horizontal part of the auxiliary tool close to the displacement system, and a water inlet is arranged at the top of the water storage cavity. The laser detection tool and detection method for the multi-wire cutting workpieces are used for laser detection of the tension of molybdenum wire by a laser sensor, and a cylinder is started to drive a nylon roller to drive the molybdenum wire to be adjusted in lifting, so that the tension adjustment of the molybdenum wire is completed. When cutting, the cooling water is transmitted to the first guide roller by the first connecting piece, the molybdenum wire is cooled and radiated by the first guide roller, and then is scraped by the nylon roller, so that the efficiency of molybdenum wire radiating is improved, and the accuracy of molybdenum wire cutting in the later stage is ensured.

This invention discloses a novel transformer, belonging to the field of vehicle-mounted transformer technology. It includes a base, with a metal cover fixedly mounted on the top of the base. A magnetic core is embedded inside the metal cover, and the bottom of the magnetic core is fixedly mounted on the top of the base. A heat dissipation vent is provided on the side end face of the metal cover for ventilation. In this invention, a linear moving shaft also applies a thrust to an insulating ejector shaft via a linear pushing shaft. Under the action of this thrust, the insulating pushing shaft moves towards the external connector. The external connector detaches from the inside of the plug-in type connector under the action of the thrust. Since the sealing cover lacks support from the external connector, it closes under the return force of the adapter spring sleeved on the outer shaft surface of the adapter shaft. With the addition of a sealing gasket, the sealing at the plug-in type connector is effectively guaranteed, preventing water from seeping into the interior of the metal cover through the plug-in type connector, further enhancing the waterproof protection of the magnetic core.
