The application discloses an auxiliary door opening device of a refrigerator door frame assembly, which comprises a box body and a door body, a push rod, the push rod is slidably connected with the box body, the first end of the push rod is connected with the door body, at least one side of the push rod is provided with a sliding surface, the width from the first end to the second end of the push rod on the other side of the push rod is gradually reduced, a clamping driving part is arranged on the box body, the clamping driving part is provided with a pushing piece matched with the sliding surface, the pushing piece is arranged in a track cavity, an elastic piece is arranged between the bottom of the track cavity and the pushing piece, the pushing piece end is slidably matched with the sliding surface, the pushing piece end extrudes the sliding surface, the door body is subjected to a component force perpendicular to the door body, and the component force assists the door body in being opened. The door frame assembly makes the extrusion force output by the spring matched with the sliding surface, the component force of the extrusion force acting on the door body is utilized to assist the door body in being opened, the device does not need to be provided with a driving motor, has the advantages of energy saving and consumption reduction, and has the advantages of simple structure, low failure rate and maintenance-free.

The embodiment of the application provides a flash alarm device, a kitchen garbage treatment system and a plug machine treatment method, and relates to the technical field of kitchen garbage treatment. The flash alarm device comprises a flash body, a flash cover, a travel switch and an elastic piece. The flash body has a flash port, the flash cover is movably matched with the flash body, and the flash cover is used for opening or closing the flash port. The travel switch is arranged on the flash body and is used for outputting a flash alarm signal in a triggering case. The elastic piece is arranged on the travel switch, the elastic piece is used for being clamped with the flash cover to keep the closing state of the flash cover on the flash port, and the elastic piece is used for triggering the travel switch in a case that the material overflows from the flash port and pushes open the flash cover, so that the flash cover is separated from the elastic piece. The flash alarm device has high detection accuracy and good reliability, can treat the plug machine fault in a short time, quickly recovers production, and improves production efficiency.

This utility model provides an automatic reset protective device, including a base and a protective cover. The base has a through hole, and the protective cover covers the edge of the through hole. The protective cover has a support part that passes through the through hole and is rotatably connected to the base. A torsion spring is also provided, with its two torsion arms abutting against the surfaces of the support part and the base, forming an angle, respectively, enabling the protective cover to close automatically. The protective cover is divided into a small split cover and a large split cover. The small split cover is fixed to the edge of the through hole in the base, and the large split cover rotates relative to the base via the support part. A magnet or magnetic metal is installed on the surface of the large split cover. The external magnetic force of the magnet or magnetic metal overcomes the torsion force of the torsion spring, opening the large split cover. No separate protective cover handle is required, and the device design is simple and aesthetically pleasing.

The utility model discloses automatic bagging equipment which comprises a bag body conveying belt, a bag opening assembly and a bag sealing assembly are arranged on the conveying path of the bag body conveying belt, and a bag opening assembly and a charging assembly are arranged at the position corresponding to the bag opening assembly. The heat-sealing cutter is connected with the first lifting driving assembly, a cutter plate strip is arranged corresponding to the heat-sealing cutter, and the heat-sealing cutter and the cutter plate strip are matched to be used for cutting off and heat-sealing a bag opening of a packaging bag. The sealing and cutting device is simple in structure, reasonable in design and capable of achieving heat-sealing type sealing and cutting of the bag opening of the packaging bag, and the sealing quality of the packaging bag is further improved.
