Description

Technical Field

[0001] This utility model belongs to the field of trash can technology, and in particular relates to a medical trash can with solid-liquid separation function. Background Technology

[0002] Medical waste bins with solid-liquid separation capabilities are specialized medical cleaning equipment in the field of waste bin technology. They are primarily used for collecting medical waste in hospital clinics, outpatient departments, and community health service centers. These bins effectively separate solid medical waste from liquid waste and possess sterilization and protection capabilities, reducing bacterial growth and contamination caused by the mixing of solid and liquid waste. They are a core component of infection control systems in medical facilities, ensuring environmental hygiene. Their solid-liquid separation efficiency, sterilization and protection effects, and ease of use directly impact the standardization of pre-treatment of medical waste and the overall hygiene and safety level of the facility.

[0003] In the actual scenario of daily medical waste collection in medical facilities, traditional medical waste bins have many obvious shortcomings. Traditional medical waste bins are mostly single-bin structures without dedicated solid-liquid separation devices. Solid medical waste accumulates mixed with liquid waste such as drug residues and disinfectant wastewater, increasing the difficulty of subsequent waste sorting and processing, and easily leading to bacterial growth and odor generation inside the bin, thus increasing the risk of hospital-acquired infections. Some simple solid-liquid separation bins lack sterilization functions, and the inner bin is inconvenient to handle, requiring overall transport and emptying, which easily causes leakage. Furthermore, traditional waste bins lack stable moving and fixing structures, making them prone to tipping over when frequently moved in treatment areas, further exacerbating the risk of medical contamination. They fail to meet the core needs of medical facilities for standardized and hygienic medical waste collection. Therefore, we propose a medical waste bin with solid-liquid separation capabilities. Summary of the Invention

[0004] The purpose of this invention is to provide a medical waste bin with solid-liquid separation function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A medical waste bin with solid-liquid separation function includes: The outer barrel has openings on its front and top sides and is hollow inside.

The anti-clogging protrusion 15 can prevent the filter holes 14 from being blocked by solid waste, ensuring smooth diversion.

[0032] Double sterilization protection: Connect the plug 18 of the inner barrel 2 to the socket 19 of the outer barrel 1, start the electric heating element 17 to sterilize the solid waste in the inner barrel 2 at high temperature; at the same time, turn on the ultraviolet sterilization lamp 21 to sterilize the area below the liquid storage hopper 11 and the liquid collection box 3 area with ultraviolet light, forming double protection and reducing the risk of bacterial growth.

[0033] Classified cleaning and maintenance: When solid waste accumulates to a certain amount, the inner barrel 2 is taken out through the hidden pull groove 23 for dumping; the valve of the liquid storage hopper 11 is opened to discharge the temporary liquid into the liquid collection box 3, and then the liquid collection box 3 is taken out through the handle for centralized treatment; after cleaning, all components are reset, the upper front cover 5, the lower front cover 6 and the upper cover 4 are closed, and the system is ready for the next use.

[0034] This implementation addresses the core pain points of medical waste collection by employing a synergistic design that combines a layered solid-liquid separation structure, electric heating and ultraviolet dual sterilization, magnetic opening and closing, and a concealed retrieval structure. This achieves standardized and hygienic collection of medical waste, effectively overcoming the technical limitations of traditional medical waste bins and meeting the infection control and waste collection needs of various medical facilities.
