Mobile Negative Pressure Toilet Ensures Air Quality

The mobile negative pressure toilet ensures the direction of air flow through specific design, achieving effective ventilation and creating a negative pressure space. Details are as follows:

Air intake path: Air enters through the ventilation openings on the toilet door. This design serves as the starting point for the entire air flow. The reasonable placement of the ventilation openings can guide fresh outside air into the interior space of the toilet in an orderly manner, providing a foundation for subsequent air circulation and ventilation.

Function of the 'air draft' device: An 'air draft' device is installed at a low position beside the toilet cubicle. Utilizing aerodynamic principles, when air enters the toilet, the 'air draft' device generates an upward suction force, prompting the air to flow in a specific direction. This suction force helps direct potentially contaminated odors within the toilet downward, preventing their random dispersion, especially preventing odors from rising into the respiratory tracts of toilet users, thereby ensuring the air quality of the toilet environment.

Coordination with the top ventilation device: A ventilation device is installed at the top of the toilet, working in conjunction with the ventilation openings on the door and the 'air draft' device. The top ventilation device can expel the air that has circulated inside the toilet to the outside, forming a complete air circulation path. Fresh air enters through the ventilation openings on the door, is guided by the 'air draft' device and circulates inside the toilet, and is then expelled by the top ventilation device, keeping the air inside the toilet in a constant state of flow.

Formation of a negative pressure space: Through the above-mentioned designs for air intake, internal guidance, and exhaust, the entire toilet space controls the direction of air flow, ensuring ventilation effectiveness. At the same time, as the top ventilation device continuously expels air from inside the toilet, the air pressure inside the toilet is lower than the outside atmospheric pressure, creating a negative pressure space. In this negative pressure environment, outside air will continuously flow into the toilet, further ensuring the freshness of the air inside the toilet and effectively preventing the escape of odors.
