Abstract
The object of the present invention is to reduce the exposure of polluted air to a baby, and in particular to minimize the pollutions inhaled by a baby when strolling, walking or transporting a baby in an exterior environment. The object is attained by providing a portable device for filtering air, the device being adapted to be arranged in association with a top end of a baby-transporting device. With such an air-filtering device, air from outside of the baby-transporting device may be filtered and purified before being provided in a well-distributed manner to the area of the baby-transporting device where a baby is positioned.
Claims17
A portable air-filtering device, the air-filtering device being configured to be arranged in association with a top end of a baby-transporting device, said top end being a part of the baby transporting device where a baby's head is positioned, or a part close to or directly adjacent to a part where the baby's head is positioned, wherein the air-filtering device comprises:
- an air-impermeable back layer;
- an air-permeable front layer arranged opposite to the back layer, wherein the air-filtering device is configured to be arranged with the front layer directed towards an inner area of the baby-transporting device;
- said back layer and front layer being arranged to form an internal cavity there between;
- a first air inlet arranged in the back layer in fluid communication with the internal cavity;
- an outer air filter arranged to cover the first air inlet;
- a first power driven ventilator arranged to draw air from an external surrounding through the first air inlet into the internal cavity, so that an overpressure is generated in the cavity;
- a baffle arranged in the internal cavity to direct the air inside the internal cavity;
- and
- an inner air filter arranged to face the inner area of the baby-transporting device,
- wherein the overpressure in the internal cavity will force the air to flow through said front layer towards the inner area, wherein the front layer comprises a material configured such that the air will be evenly distributed within the front layer before exiting said front layer whereby the air will be evenly distributed through the inner air filter, thereby providing a local environment of purified air in the inner area of the baby-transporting device,
- and wherein the inner air filter is adapted to remove microparticles having a size of 0.1-1000 μm from the air.
