This utility model relates to the field of detection device technology and discloses a detection device for a fire alarm, including a smoke storage box. A sealing cover is rotatably connected to the left side of the top of the smoke storage box. A support frame is fixedly installed at the top of the inner cavity of the smoke storage box. Magnets are fixedly installed at the right ends of both the sealing cover and the support frame. A steel wire rope is fixedly installed at the right end of the top of the sealing cover. By pulling the steel wire rope downwards, the sealing cover can be rotated upwards to open the top of the smoke storage box. The smoke storage box is then placed over the smoke alarm for detection. After detection, the steel wire rope is released. The compressed push spring, under its elastic force, moves the push rod upwards, pushing the extension block to rotate. This, in turn, causes the sealing cover to rotate in the opposite direction, sealing the smoke storage box and preventing smoke emission during movement. This reduces the use of smoke pellets and lowers detection costs.

This utility model belongs to the field of kitchenware manufacturing, specifically a sealing device for cast iron woks. It includes a main body with a movable module inside, a heating module above the movable module, a limiting module on the right side of the heating module, and a striking module on the right side of the limiting module. The striking module includes a fixed plate, a limiting block, an electric rotating shaft, an extension arm, a wear-resistant pad, a vibration motor, and a striking hammer. The limiting block is installed on the left side of the fixed plate, and an electric rotating shaft is located inside the limiting block. An extension arm is installed on the left side of the electric rotating shaft, and a wear-resistant pad is adhered to the end of the extension arm. This utility model provides more uniform force and a faster striking frequency when sealing the edge of the wok, effectively reducing the labor intensity of operators. It is adjustable and can seal woks of different sizes. It also has a heat insulation effect, effectively isolating heat and reducing safety hazards.

The utility model discloses an injection molding machine for producing plastic floor belongs to floor production field, including extrusion cylinder, the fixed coupling of feeding pipe has on extrusion cylinder, is provided with rotating mechanism in extrusion cylinder, and rotating mechanism includes auger shaft, and the fixed coupling of motor has in the center position of extrusion cylinder one end, and the fixed coupling of extrusion head has in the end of extrusion cylinder away from motor. Advantageous effects lie in: set up connecting mechanism and vibration mechanism, through the setting of several material distribution plates on the conveying box, the hot plastic raw material flowing out in the extrusion head is guided to the material distribution plate respectively, and is injected into the mold through each injection tube, can make the hot plastic raw material enter the mold and will be fitted floor forming structure, avoid injection molding floor everywhere raw material distribution and uneven cooling, and through setting vibration mechanism, can improve the flowability of hot plastic raw material in the material distribution plate, make it more evenly from injection tube spouts, further improve injection uniformity.

The utility model relates to a dust collector, including work table, the upper end surface fixed connection of work table has dust removal box, the inside lower fixed surface connection of dust removal box has collection frame, the inside upper end fixed connection of collection frame has the clamping seat, the upper end of clamping seat is provided with with the inside upper fixed surface connection of dust removal box electric push rod no.

This utility model discloses a dual-source heat pump, belonging to the technical field of dual-source heat pumps. A dual-source heat pump includes fins fixed to both sides of the dual-source heat pump unit and two fans installed on the upper surface of the unit. The top of the dual-source heat pump unit forms a cavity through the two fins and side walls. The sealing assembly includes multiple guide vanes rotating at the top of the cavity via connecting shafts, which seal the fan ventilation holes. This utility model uses a solenoid valve to introduce a portion of the high-temperature gas about to enter the condenser into the air duct. Multiple hoses then allow the high-temperature gas to be ejected through the outlet pipe, heating the fins and evaporating the frost on the fin surface. Simultaneously, the sealing assembly seals the fan ventilation holes, preventing heat dissipation and concentrating heat inside the cavity to continuously heat the fins and prevent re-frost formation.

This utility model relates to the field of manufactured sand production technology, and in particular to a crushing and grinding equipment for producing circular manufactured sand. It includes a controller fixedly installed on the surface of the housing, a hopper fixedly installed in the middle of the top of the housing, and dust collection boxes fixedly installed on both sides of the top of the housing. Through the two partitions, when raw materials are poured into the hopper, they come into contact with the partitions. The partitions are compressed by the downward force of the raw materials, allowing the elastic seat to deform and open, thus allowing the raw materials to enter the housing for crushing. After all the material has been discharged, the elastic seat returns to its original shape, allowing the two partitions to close again. This prevents dust generated during crushing from escaping from the hopper. Simultaneously, a fan draws the dust into the dust collection boxes, where it is adsorbed onto the filter plates, further preventing dust from spreading and avoiding harm to the human body.

The application discloses a negative pressure head cover capable of preventing droplet transmission and a use method thereof, and belongs to the technical field of medical devices. The negative pressure head cover comprises a sealed head cover, a sealed face cover, and a negative pressure pipe. The sealed head cover is transparent. The sealed face cover is detachably arranged on the outer side of the sealed head cover and is transparent. The negative pressure pipe is arranged on the outer side of a sterilization assembly. The application effectively solves the problem that the exhaled gas cannot be sterilized before being discharged, thereby realizing that the negative pressure pipe can extract the gas in the sealed face cover, input the gas into the inside of the sterilization assembly for sterilization, and then discharge the gas through the exhaust pipe, so that the exhaled gas of the patient can be sterilized before being discharged, the gas in the sealed head cover is prevented from being emitted into the air when the sealed head cover is removed, and the effect of preventing droplet transmission is improved.
