The present disclosure relates to a Type-C adapter including a Type-C interface connected to the Type-C interface of a terminal, wherein when the Type-C interface is connected to the Type-C interface,the idle pin of the Type-C interface is connected to a first component and the first component is connected to a first level; an audio interface connected to the plug of an audio device; a first spring disposed in the audio interface and connected to the idle pin; and a second spring disposed in the audio interface and connected to the second component of the audio interface, wherein the second component is connected to a second level. When the audio interface is disconnected from the plug of the audio device, the first spring and the second spring are disconnected. According to the embodiment of the present disclosure, the MIC pin can be powered off in a shorter time while the plug of the audio device is pulled out of the audio interface, so as to ensure that the MIC pin has been poweredoff when the GND pin of the plug of the audio device comes to contact with the MIC pin, thereby preventing the current in the MIC pin from flowing into the plug of the audio device and causing POP tones.

The invention discloses an electronic control VE type distribution pump and a flameout method thereof. The electronic control VE type distribution pump comprises an oil pump assembly, an oil inlet pipe and an oil inlet screw, wherein an oil inlet of a pump body of the oil pump assembly is connected with the oil inlet screw, the oil inlet screw is connected to one end of the oil inlet pipe, the other end of the oil inlet pipe is connected to an oil tank, an oil inlet electromagnetic valve is arranged on a pump head of the oil pump assembly, an oil inlet hole, an oil outlet hole and a guide holewhich is formed between the oil inlet hole and the oil outlet hole are formed in the oil inlet screw, an oil cut-off electromagnetic valve is arranged at the upper part, located at of the guide hole,in the oil inlet screw, and an armature of the oil cut-off electromagnetic valve is arranged in the guide hole to move back and forth so as to enable the oil inlet hole and the oil outlet hole of theoil inlet screw to communicate with each other or to be closed. According to the electronic control VE type distribution pump and the flameout method thereof, the oil inlet screw is designed to be the provided with the oil cut-off electromagnetic valve capable of cutting off oil inlet of the electronic control VE type distribution pump, when the electromagnetic valve is powered off, oil inlet ofthe electronic control VE type distribution pump can be cut off, and by means of the coordination of the power failure and oil cut-off of an oil inlet electromagnetic valve of the pump head, the powerfailure of the electronic control VE type distribution pump can be realized so that an engine can be rapidly stopped.

The invention provides a household electric cooker. The household electric cooker comprises a magnetic steel temperature limiter, the magnetic steel temperature limiter comprises an aluminum cover, asoft magnet, a soft support, a hard magnet, a hard support, an inner spring, a small cup and a pull rod, the soft magnet, the soft support, the hard magnet, the hard support and the inner spring are all located in the small cup, one end of the pull rod is fixedly connected with the hard support, the other end of the pull rod penetrates out of the small cup and is movably arranged, the inner springis arranged between the hard support and the aluminum cover, the soft magnet and the hard magnet are both located in the inner spring, the magnetic steel temperature limiter further comprises a temperature sensing deformation component, the temperature sensing deformation component is located in the inner spring, one end of the temperature sensing deformation component is fixedly connected with the soft support, and the other end of the temperature sensing deformation component directly faces the hard support. The problem that a magnetic steel temperature limiter is burnt down and even a firedisaster is caused due to the fact that a heat preservation piece and a contact on a lever of an electric cooker are sintered and bonded together and an inner spring in the magnetic steel temperaturelimiter cannot drive the heat preservation piece to be separated from the lever contact through a pull rod can be avoided.

The invention discloses a switch core part structure capable of preventing an action dead point. The switch core part structure comprises a base, a base assembly and a movable assembly; a pass-through hole is formed in the top surface of the base; the base assembly comprises a lower cover, a left normally-open connecting-inserting assembly, a right normally-open connecting-inserting assembly, a left normally-closed connecting-inserting assembly and a right normally-closed connecting-inserting assembly; rectangular holes are formed in the two side edges of the lower cover; positioning blocks are embedded on the rectangular holes respectively; the movable assembly comprises a movable rod, a pressing block, elastic assemblies, a movable contact piece base, a movable contact piece and a reset spring; a groove is formed in the top end of the movable rod; a convex block is arranged at the bottom end of the pressing block; the convex block is embedded in the groove; the reset spring is arranged below the movable contact piece base; the bottom end of the movable rod is connected with the top end of the reset spring; the elastic assemblies are connected with the two sides of the movable rod; through holes are formed in the side walls of the movable contact piece base; the elastic assemblies passes through the through holes to be in contact with the corresponding positioning blocks; and the movable contact piece is arranged on the movable contact piece base.
