DETAILED DESCRIPTION

(6) Throughout the present disclosure, the term “automobile accessory power outlet” may be interchangeably used with “power outlet of a vehicle”

(7) An air treatment device 100 according to the inventive concept will be described with reference to FIG. 1, which illustrates a perspective view of the air treatment device 100. The air treatment device 100 comprises a device body 102 having a central axis A. The device body comprises a supporting structure 104 being substantially transverse to the central axis A. The device body 102 is here illustrated in the shape of a rectangular cuboid. However, it will be appreciated that other geometrical shapes may be envisaged within the scope of the inventive concept.

(8) The device body 102 further comprises a side section 106 being substantially parallel to the central axis A. Here, the side section 106 encloses the central axis A, and thus defines an inner volume for housing other parts of the air treatment device 100.

(9) Along at least part of a circumference of the side section 106, a device body air inlet 108 is arranged. The device body air inlet may be formed by a gap between the supporting structure 104 and the side section 106. The side section 106 may be arranged to extend further away from the central axis A as compared to the supporting structure 104. Hereby, the device body air inlet 108 may be at least partly hidden when the air treatment device is viewed from above.

(10) Along at least part of a circumference of the side section 106, a device body air outlet 110 is arranged. The device body air outlet may be formed by an array of holes in the side section 106. The device body air outlet 110 is here arranged above the device body air inlet 108 with respect to a first direction D.sub.1 being parallel to the central axis A.

(11) Referring now to FIG. 2, the air treatment device 100 further comprises an air treatment section arranged in the device body 102 between the device body air inlet 108 and the device body air outlet 110. The air treatment section is configured to treat a flow of air drawn via the device body air inlet 108.

(12) The air treatment section comprises a fan arrangement 112 for generating the flow of air from the device body air inlet 108 to the device body air outlet 110. The fan arrangement may comprise a fan unit configured to rotate around the central axis A. A fan arrangement inlet 114 may be arranged in the air treatment section. The fan arrangement inlet 114 here has an annular opening being substantially transverse to the central axis A.

(13) The air treatment section comprises an ionizing arrangement (not shown). The ionizing arrangement (not shown) comprises a collector electrode (not shown) and an emitter electrode (not shown). The collector electrode is arranged along a circumference of the annular opening of the fan arrangement inlet 114 and, the emitter electrode is arranged in a center of the annular opening of the fan arrangement inlet 114. The emitter electrode may be arranged closer to a center of the annular opening than the collector electrode.

(14) The fan arrangement 112 and the ionizing arrangement (not shown) is here enclosed by an inner body 120 having an inner body air outlet 124 arranged along at least part of a circumference of the inner body 120.

(15) The air treatment section comprises a filter 122 arranged along at least part of a circumference of the side section 106. The filter 122 extends in the first direction D.sub.1. The filter 122 comprises an upper end 126 and a lower end 128 in the first direction D.sub.1. The ionizing arrangement is arranged upstream of the filter 122 with respect to a direction of flow from the device body air inlet 108 to the device body air outlet 110, and the ionizing arrangement and the fan arrangement 112 are arranged between the upper and lower end 126, 128. In other words, a periphery of the filter 122 may define imaginary limits along the central axis A, and the ionizing arrangement and the fan arrangement 112 may be arranged within the imaginary limits. Here, the filter 122 and the device body air outlet 110 extend substantially the same distance in the first direction D.sub.1. The filter 122 may comprise a filter media being supported by a frame. It should be noted that because of the nature of an exploded view, the upper and lower end 126, 128 as well as the distance which the filter 122 and the device body air outlet 110 extend may not be accurately illustrated.

(16) Referring now to FIG. 3, a clearer view of the device body air inlet 108 can be seen. Further, the upper end 126 and lower end 128 of the filter 122 is here illustrated more clearly compared to FIG. 2. The fan arrangement and ionizing arrangement is arranged between the upper and lower end 126, 128. The device body 102 of the air treatment device 100 here comprises a top section being substantially parallel to the central axis. It may be noted that the device body air outlet 110 is here confined to the side section 106. Hereby, objects may be placed on the top section without impacting the efficiency and/or the air flow of the air treatment device. A clearer view of the supporting structure 104 can here also be seen.

(17) Referring now to FIG. 4, the emitter electrode 130 and collector electrode 132 is shown as arranged on the fan arrangement inlet 114. Here, the emitter electrode 130 is an ionizing brush, and the collector electrode 132 is a grounding cylinder arranged along the circumference of the fan arrangement inlet 114. The device body air inlet 108 can also be seen in this view. It is to be understood that the emitter electrode 130 may protrude further towards the center of the fan arrangement inlet 114 than shown in this figure. Also, it is to be understood that the collector electrode 132 does not necessarily have to run along the full length of the circumference of the fan arrangement inlet 114.

(18) The inventive concept has mainly been described above with reference to a few embodiments. However, as is readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the inventive concept, as defined by the appended patent claims.
