Abstract
An air treatment device includes a housing and a pad holder mounted within the housing. The pad holder has an opening providing access to a support surface for a scented pad. When positioned on the support surface the scented pad has a first end portion remote from the opening and a second end portion adjacent the opening. A mechanism associated with the pad holder is configured to at least partially remove the scented pad from the pad holder. The mechanism includes a lever arm and a pad pusher connected to the lever arm. The lever arm is configured such that movement of the lever arm pushes the pad pusher along the support surface toward the opening, the pad pusher engaging the first end portion of the scented pad and moving the second end portion of the scented pad at least partially out of the pad holder opening.
