Ambient Air Purification Device, Road Vehicle Having an Ambient Air Purification Device and Filter Element

Abstract

An ambient air purification device for a road vehicle for removing dust, particulate matter, and / or gases from ambient air has one or more filter elements. The ambient air purification device is attachable in an external region to a vehicle rear of the road vehicle by a releasable coupling. The ambient air purification device has at least one mating coupling of the releasable coupling, wherein the at least one mating coupling is coupled to a vehicle-side coupling component of the releasable coupling. A road vehicle provided with such an ambient air purification device is provided.

AI Technical Summary

Benefits of technology

The invention aims to solve the problems of previous air purification devices by providing an easy and quick way to attach and remove the device from a vehicle. The goal is to make it more user-friendly and efficient.

Problems solved by technology

Due to the progressing urbanization, there is the problem that, primarily in metropolitan areas, limit values for particulate matter and / or gases, such as ozone, NOx, CO, in the ambient air may be exceeded by several orders of magnitudes by industrial pollution, the road traffic, and private fireplaces, primarily in adverse weather conditions (no rain, inversion, minimal wind speed, no air exchange between air layers).

Disadvantageously, noteworthy filter surfaces for filtering a meaningful quantity of air can hardly be provided at the installation spaces described therein.

The solutions known from the prior art are disadvantageously permanently fastened to the vehicle.

However, the aforementioned weather conditions with bad air quality, in particular in regard to particle load and harmful gas load, in particular increased particulate matter load, exist mostly only for a limited period of time.
