Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly public toilets, and more specifically, to a mobile environmentally friendly public toilet with an exhaust and ventilation device on the top. Background Art

[0002] Mobile toilets refer to facilities that can be moved as a whole and set up at locations or places with fixed or temporary needs to provide toilet services to the public and customers. Mobile toilets originated from people's temporary and phased needs for toilets in certain specific occasions. For example, in construction sites, shipbuilding slipways and other workplaces, mobile toilets are set up on slipways and construction sites to reduce the time workers spend traveling to and from fixed toilets and improve labor efficiency; large gatherings, sports events, and other occasions have temporary needs for toilets for a large number of spectators, etc. When a large number of people use a public toilet, it is easy for odors to be generated inside the toilet. If the odors are not treated, it will seriously affect people's user experience. Common public toilets have several windows on the outside to disperse the air, but the effect is generally poor. For this reason, we proposed a mobile and environmentally friendly public toilet with an exhaust ventilation device on the top. Utility Model Content
