The present invention is a device for playing a cartridge (42) for dispersing scented materials into a room. The cartridge (42) generally has a plurality of scent elements supported on a rotatable disk. The device includes a housing (1,2), a blower assembly (70), a platter (19), a motor (35A), first and second sensors (52,53) and a control unit (73). The housing (1,2) has a cavity (47) for receiving the cartridge and is formed with an air intake (50) and an exhaust port (51). The blower assembly (70) is mounted within the housing (1,2) for generating an airflow by drawing air in through the air intake (50) over the cavity (47) to diffuse at least one of the plurality of scent elements out through the exhaust port (51). The platter (19) is configured to engage the rotatable disk and is rotated by the motor (35A). The platter (19), first and second sensors (52,53) and a control unit (73) cooperate to control the rotation of the disk. The device can also include a heating element (45) for activating the scent elements.

A portable humidifier (10) is provided which includes an induction heating system. The system includes an inductor coil (18) and a metal target which functions as a heating element. The metal target is positioned within a tray (14) beneath the inductor coil (18). The tray is adapted for holding water. The target is coupled to a float, which allows it to move towards or away from the inductor coil (18) depending upon the water level in the tray.

The portable air purifying device (10) is provided for removing airborne particles. The device includes a housing (12) including an exterior surface formed with an air inlet (26) and an air outlet (28). The air outlet is formed as a plurality of openings. A scroll (44) is located within the housing and has walls formed with an intake opening (194) and an exhaust port (186). The exterior surface and the walls define a cavity (76). The cavity has a first portion and a second portion. The first portion is in communication between the exhaust port and the air outlet. A fan (14) is positioned within the intake opening for drawing air in through the air inlet to pass through the scroll and the first portion of the cavity to be expelled through the air outlet while the second portion of the cavity is under a positive pressure. A filter assembly (48) is assembled within the housing between the air inlet and the fan. The device can include a second filter assembly.
摘要:
A system for monitoring a percentage of filter life remaining of a filter assembly of filter-fan devices. The system uses a single thermistor that is operated in two separate modes for monitoring the filter assembly. The thermistor is positioned in the airflow of the filter-fan adjacent to the air outlet. A first current is applied to the thermistor for determining the temperature of the airflow from a first thermistor voltage. The first thermistor voltage is responsive to the first current applied to the thermistor. A second current that is greater than the first current is applied to the heat the thermistor. The temperature of the thermistor is determined from a second thermistor voltage which is responsive to the second current applied to the thermistor. The percentage of filter life remaining of the filter assembly is determined from the temperature of the airflow and the second thermistor voltage.
摘要:
A method and circuit for monitoring the useful life of a filter for a filter-fan product. The method includes the steps of detecting use of a fan of the filter-fan product with a microprocessor, counting from a predetermined initial counter value a duration of usage of the fan with a counter of the microprocessor to determine a present counter value, sending a signal representing the present counter value from the microprocessor to a display and displaying the remaining useful life of the filter based on the signal received from the microprocessor. Use of the fan is preferably detected by detecting a position of a fan speed switch such that the microprocessor detects the speed of the fan and adjusts the rate of counting by the counter based on the detected speed of the fan. The circuit includes a microprocessor electrically connected to a fan of the filter-fan product for detecting use of the fan and a display electrically connected to the microprocessor for displaying the remaining useful life of the filter. The microprocessor includes a counter, having a predetermined initial counter value, which counts from the predetermined initial counter value a duration of usage of the fan to determine a present counter value. The microprocessor sends a signal representing the present counter value to the display which uses the signal to display the remaining useful life of the filter.
摘要:
A heater comprising two or more heating units which are rotatably attached to each other about a common axis. Preferably, each heating unit is rotatably attached to the next successive heating unit along a vertical axis by a flanged coupling. Alternatively, each heating unit is rotatably attached to the next successive heating unit along a vertical axis by a pin and slot arrangement. Each of the heating units include a housing having at least one opening and a heater element within the housing.
