Description

Technical field of the invention

The present invention relates to a removable air purification device and / or integrated into a stroller (or similar means of transport).

State of the art

The rate of global air pollution is closely monitored; constantly increasing in recent decades, global organizations and some governments are committed to reducing it. Air pollution comes mainly from the release of gases and particles, toxic when in large quantities, in particular factories and means of transport (cars, boats, planes, trains, etc.). In particular, prolonged exposure to polluted air leads to medical complications, particularly in the lungs, heart and brain, especially for young children for whom these organs are still developing.

Many indoor air purification systems exist; used for (semi) closed rooms or personal space, toxic gases and fine particles are largely eliminated. Some of these systems can be used outside, but limiting their effectiveness. Currently, a limited number of systems exist for purifying personal air outdoors. In particular, no intelligent, removable system or one directly integrated into a stroller (or similar means of transport) is known to be commercially available.

The stroller remains one of the most common means of transporting young children. However, outside, the child is directly exposed to polluted air: mainly due to cars often having exhaust pipes at the child's level, cigarette smoke or equivalent and dust.

More precisely, these objectives are achieved using a removable and / or integrated air purification device in a stroller (or similar means of transport) with a transparent anti-UV cover, characterized in that it comprises at least one air purification module comprising at least one

motor, filter and sensor tube system for measuring the dust / particle rate. and at least one module gas toxic and of 4 Statement of the invention So this purification device air removable and or

integrating with a stroller (or similar means of transport) reduces the exposure of young children to toxic gases and dust / particles. By collecting data on toxic gas and particulate matter levels in a raw way and treated inside and outside of the stroller (or similar means of transport) thanks to sensors, the air purifier starts automatically to clean the air inside the stroller (or similar means of transport) if the air pollution rate outside is too high; so that the indoor air pollution level is satisfactory. The interior of the stroller (or similar means of transport) consists of the semi-enclosed space delimited by the transparent anti-UV cover. The outside of the stroller (or similar means of transport) consists of the space which is not inside and delimited by the transparent anti-UV cover.

It is a very easy to use system since you just have to

The user moves the stroller (or similar means of transport) so that the whole system starts. Lights indicating the general rate of air pollution also allow the user to know the general level of air pollution. It is a system recovering all the parameters of pollution of the surrounding air. It can be used in any environment where it is appropriate to use a stroller (or similar means of transport). Can be used daily, only the removable battery needs to be recharged. Furthermore, the presence of the micro generator makes it possible to considerably increase the autonomy of the system. Its measurements are also automatically sent to the user's mobile application via a wireless connection.

The invention achieves the objectives, thus, the air purification system according to the invention does indeed reduce the exposure of young children to polluted air. In addition, from the data collected, the average air pollution as a function of time and the location can be calculated in order to observe, analyze and model the evolution of air pollution .

The secondary claims set out optional features of the invention.
