Description

Technical Field

[0001] This utility model belongs to the technical field of sterilization and purification devices, and specifically relates to a small sterilization and purification device for a closed space. Background Technology

[0002] The JC cabin is a confined space, and the ship's toilets are characterized by high humidity, high pollution, and a high rate of bacterial growth. The main pollutants are malodorous gases such as ammonia, hydrogen sulfide, methanethiol, and indole. In addition to sensory irritation, these malodorous gases are also physiologically toxic to humans. Continuous or frequent exposure to malodorous environments can cause loss of appetite, nausea, and even vomiting, which can further develop into restlessness, poor concentration, reduced work efficiency, and impaired judgment and memory. These odorous substances seriously affect the work and rest of the crew.

[0003] While air purification equipment exists and plays a role in improving air quality, it has certain limitations. First, filter-type equipment requires compatibility with system piping, valves, and fans. However, the filter resistance is not well-matched with the system fan, resulting in high vibration and noise. Continuous operation can disrupt staff rest, forcing intermittent operation and insufficient running time, thus affecting the overall purification effect. Second, equipment with built-in fans is too bulky, taking up considerable space in small spaces such as restrooms, further restricting staff movement. Third, current equipment lacks sterilization capabilities, failing to achieve the combined effect of sterilization and purification. Utility Model Content

[0004] The purpose of this invention is to provide a small-scale sterilization and purification device for enclosed spaces, which solves the technical problems of existing technologies such as large size, high noise, inconvenient installation, and inability to sterilize.

Mounting holes are provided at the four corners of the cover plate, the purification filter element, and the base plate. An air inlet is located in the center of the base plate. The cover plate is mounted on top of the purification filter element, and the purification filter element is mounted on the base plate. Air outlets are provided around the purification filter element. A fixing plate is installed in the center of the cover plate, and the fan is mounted on the fixing plate. The fan's air inlet side faces the air inlet of the base plate, and its air outlet side faces the air outlet of the purification filter element.

[0006] In application, the fan is fixed to the fixing plate by bolts, the fixing plate is fixed to the cover plate by bolts, and the cover plate is fixed to the base plate by bolts passing through the purification filter element. After the fan starts running, the airflow enters the air inlet side of the fan from the air inlet, and the air outlet side of the fan sends the airflow into the purification filter element. Finally, the airflow enters the sealed space through the air outlet of the purification filter element.

[0007] In a further preferred embodiment, a pressure plate is connected to the upper side of the cover plate, through which the internal fan cable passes. The pressure plate can fix the cable, ensuring safety during use, while also tidying up the cable and improving aesthetics. The pressure plate is fixed to the upper side of the cover plate by bolts.
