Description

Technical Field

[0001] The utility model relates to the technical field of toilet ventilation, in particular to a ventilation device for polluted gases in an epidemic prevention toilet. Background Art

[0002] Epidemic prevention is a general term for measures to prevent, control and eliminate infectious diseases, which are divided into regular and post-epidemic types, including vaccination, quarantine, census and management of sources of infection, routes of transmission and susceptible populations. In order to improve people's convenience, public toilets are built in many places. Since there are many mobile populations in public toilets and the sanitary environment is difficult to manage, it is necessary to install polluted gas ventilation devices in public toilets to improve the epidemic prevention effect of public toilets.

[0003] In order to improve the epidemic prevention effect of toilets, the prior art has made many improvements to toilets. For example, the patent with patent publication number CN209163531U discloses an assembled public toilet, including a bottom plate, a steel frame, assembled wall panels, a wall surface and a connecting piece; a plurality of ventilation windows and doors are arranged side by side on the side wall; an exhaust window is arranged on the top wall obliquely above the ventilation window; a filter window is movably arranged on the exhaust window; a negative pressure fan is arranged on the outside of the filter window and the air inlet of the negative pressure fan is aligned with the grid on the filter window; the two sides of the connecting piece are chamfered symmetrically up and down; the upper and lower chamfers form a convex platform on both sides of the connecting piece; grooves are processed inwardly on the surfaces of both sides of the assembled wall panels; a plurality of springs are connected between the protrusion of the convex platform and the bottom of the groove; the technical solution adopted by the utility model solves the problem that the existing assembled public toilets are not equipped with special ventilation equipment, resulting in low comfort of air conditions; and the assembled public toilets built in special geographical and weather conditions have weak earthquake resistance and impact resistance, resulting in a short service life.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative document, an exhaust window is set up, and an exhaust fan installed outside the toilet is used to discharge the polluted gas in the toilet, so as to achieve the effect of epidemic prevention inside the toilet. However, in reality, since there are many side seats in the public toilet, each side seat is blocked by partitions and door panels, and several partitions and door panels affect the circulation of air inside the side seats. When the person in front finishes using the toilet in the side seat, the person behind enters the side seat. Since the air in the side seat has not yet dissipated, the air exhaled by the person in front and the smell of feces are still floating in the side seat, which may cause alternating infection of pathogens and reduce the epidemic prevention effect. Therefore, this field is in urgent need of improving the ventilation device for polluted gases in epidemic prevention toilets to solve the defects of the existing technology. Utility Model Content
