Technical Field

[0001] The utility model belongs to the technical field of ventilation equipment, and in particular relates to multifunctional ventilation equipment for inpatient wards. Background Art

[0002] There are all kinds of patients living in the hospital wards. The air is extremely complex and the spread of germs is serious. At this time, ventilation equipment is needed for auxiliary ventilation. In order to prevent secondary infection caused by polluted air in the ward, ventilation is needed.

[0003] After searching, the patent announcement number CN209840360U discloses a ventilation device for critical medical care wards, including a main shell, a coarse filter and an exhaust fan, a heating port is provided on the right side of the main shell, and an exhaust port is provided on the left side of the main shell, the coarse filter is bolted on the right side of the main shell, an electric heating rod is installed inside the heating port, and a drain port is embedded below the heating port, the exhaust fan is bolted inside the exhaust port, the exhaust pipe is connected to the ventilation pipe through a connecting pipe, and the right side of the ventilation pipe is screwed with an end cap, a slide is provided in the front of the middle of the ventilation pipe, and a filter core cover is installed inside the slide, and a fine filter is embedded inside the filter core cover. The ventilation device for critical medical care wards adopts a split-flow design, which effectively increases the workload, and is used with a filter core cover that is easy to disassemble, so that the filter core cover can be effectively cleaned, thereby ensuring the quality of the air.

[0004] When the existing ward ventilation equipment is actually used, it generally discharges the air in the ward directly into the external environment. The air in the ward contains certain germs, particles or suspended matter. If the air in the ward is directly discharged into the external environment, it will cause certain pollution to the external environment. For this reason, we propose a multifunctional ventilation equipment for inpatient wards to solve the existing problems. Utility Model Content
