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.

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.
