    • Disclosed are devices for dispensing air treatment chemicals. There is a substrate bearing a first volatile air treatment chemical that is capable of being dispensed from the substrate when the substrate is heated, and an indicator unit holding a volatile indicator chemical separate from the first volatile air treatment chemical such that the volatile indicator chemical is capable of being dispensed from the unit when the unit is heated. The extent of dispensing of the first volatile air treatment chemical can be indicated by a visible cue whose appearance results from the dispensing of the volatile indicator chemical. In one form the unit also holds a second air treatment chemical. In another the indicator unit is a replaceable cartridge positionable more remote from the heater than the substrate.

    • Devices for dispensing air treatment chemicals are described. They have a first substrate bearing a first volatile air treatment chemical that is dispensed when the first substrate is heated, and a second substrate bearing a second volatile air treatment chemical that is dispensed from the second substrate when the second substrate is heated. The substrates are positioned in stacked fashion relative to each other, optionally with a permeable membrane there between. There may also be a use-up cue indicator unit coordinated with use of the chemicals. The first and second substrates and indicator unit can be in a single replaceable cartridge unit, preferably with the second substrate in the form of a porous ring that houses the indicator unit.
    • 描述了用于分配空气处理化学品的装置。 它们具有第一衬底,其承载第一挥发性空气处理化学品,其在第一衬底被加热时被分配;以及第二衬底,其承载第二挥发性空气处理化学品,当第二衬底被加热时,该第二衬底从第二衬底分配。 衬底相对于彼此以层叠的方式定位,任选地在其间具有可渗透的膜。 还可能存在与使用化学品协调使用的消耗指示器单元。 第一和第二基板和指示器单元可以在单个可更换的盒单元中,优选地以容纳指示器单元的多孔环形式的第二基板。
