This invention discloses an air pollution circulation and treatment device, belonging to the field of air pollution control technology. It includes a frame, a gas-liquid separation cylinder mounted on the frame, and a water tank. The gas-liquid separation cylinder has an air inlet, and the water outlet of the water tank is connected to a circulating water pump. The outlet of the circulating water pump is connected to a Venturi spray system, and a drain pipe is located at the bottom of the water tank. This invention uses a horizontal plate and a filter screen to form an independent filtration chamber within the water tank corresponding to the circulating water pump inlet. When the filter screen is clogged by dust particles, causing the liquid level inside the filtration chamber to drop, a purely mechanical rotary drive mechanism consisting of a float, magnetic metal block, magnet, rack, and ratchet assembly can be automatically triggered. Without manual intervention or an additional electrical control system, it can automatically coordinate with a scraping mechanism to clean the filter screen surface online. This effectively solves the problems of insufficient circulating water volume and water pressure drop caused by filter screen clogging, ensuring stable Venturi atomization effect and dust removal efficiency.

This utility model relates to the technical field of pre-cooling devices, and provides a pre-cooling device for preserving fruits and vegetables after harvesting. It includes a shell, a box for storing ice packs fixedly installed on the bottom inner wall of the shell; two support blocks fixedly installed on the inner walls of both sides of the box, with placement frames for storing fruits and vegetables placed on the two support blocks, each placement frame having multiple first through holes; a cover plate disposed on the shell; two mesh frames fixedly installed on the inner walls of both sides of the shell, each mesh frame having an odor-removing box for deodorization and sterilization inside; a cover fixedly installed on the cover plate; and a fixing mechanism assembled on the cover for pressing the fruits and vegetables. The pre-cooling device for preserving fruits and vegetables after harvesting provided by this solution solves the problem of existing pre-cooling devices for preserving fruits and vegetables after harvesting lacking a fixing function, leading to easy collision damage to fruits and vegetables during transportation.

This application discloses a circulating deodorization device for a urination and defecation care machine. The air from the negative pressure source fan is routed through a hose connector assembly back to the hose assembly, and then delivered to the urinal. Once the urinal is worn, it forms a relatively enclosed chamber with the body. Air enters the hose assembly from the wearable part, passes through the exhaust port of the wastewater tank, and then enters the deodorization module for continuous filtration of odorous gases. The air then enters the water vapor filtration module for moisture treatment, and finally passes through the air filtration module before returning to the negative pressure source fan inlet, forming a relatively closed circulating air path that prevents exchange with outside air. This fundamentally solves the problem of exhaust vents polluting indoor air, preventing gas exchange with the outside, deodorizing the internal circulating air, effectively preventing odor leakage, and ensuring deodorization effectiveness.

This utility model relates to the field of sterilizer filter technology, and discloses an easily disassembled plasma air sterilizer filter, including a shell, a base plate on the inner wall of the shell, an outer ring fixedly connected to the outer side of the top surface of the base plate, an inner ring fixedly connected to the middle of the top surface of the base plate, a bracket fixedly connected to the top surface of the inner ring near its edge, a top plate on the top surface of the bracket, an activated carbon filter in the middle of the top surface of the shell, a high-efficiency filter on the outer wall of the activated carbon filter, a pre-filter on the outer wall of the high-efficiency filter, an air inlet at the upper end of the outer wall of the shell, and a top cover on the top of the shell. In this utility model, the multi-layer structure of the pre-filter, high-efficiency filter, and activated carbon filter effectively improves indoor air quality and removes odors from the air. The top surface of the top plate is fixed to the bracket with screws, facilitating disassembly for cleaning and replacement of the filter elements and filters.
