Description

  The present invention relates to a fan filter clip and a fan filter for fixing a filter for filtering dust in air blown by a fan to the fan.

  As a filter attached to the electric fan, for example, a filter described in Patent Document 1 is known. This filter is attached from the front side of the protective guard of the electric fan, tied with a string. According to this filter, dust in the air blown by the fan is filtered by the filter on the front surface of the protective guard, so that the air blown forward of the fan is cleaned.

  Further, for example, in Patent Documents 2 and 3, a filter is attached to a portion where the wind enters the fan behind the protective guard of the fan, and the air blown forward of the fan is cleaned by absorbing dust. Of course, there is described a fan filter that prevents the fan blades and the protective guard outside thereof from getting dirty.

  These filters described in Patent Documents 1 to 3 are attached to a general fan having a shape in which blades are sandwiched from front and rear by a dome-shaped protective guard, that is, a so-called living fan. In this type of fan, the diameter of the joint part of the front and rear protective guards is the largest, and the diameter decreases in the front-rear direction, so it is easy to prevent the filter from moving if a filter is attached across this joint part. Can be fixed to.

  In recent years, box-type fans (so-called box fans) having blades in a rectangular parallelepiped body and cylindrical protective guards before and after the body have been developed (for example, Non-Patent Documents 1 and 2). reference.). In this kind of electric fan, since the joint part of a protection guard exists in the surface of a rectangular parallelepiped main body, the filter for general electric fans as described in patent documents 1-3 cannot be used. This is because the filter cannot be attached across the joint portion of the protective guard.
