Description

MOBILE AIR DEPURATOR. PORTABLE, SELF-CONTAINED REFERENCE CREDITED TO RELATED APPLICATION The present is a continuation in part of the co-pending patent application with serial number 08 / 683,711, issued July 18, 1996, which is a continuation in part of serial number 08 / 514,995, issued on August 14, 1995, entitled SELF-CONTAINED PORTABLE / MOUNTABLE AIR CLEANER.

BACKGROUND OF THE INVENTION The present invention relates to a portable / mountable air scrubber, and very specifically, to an air scrubber that includes a carrier handle extending from an air cleaner elongate body, and sized and configured to be mounted between rafters. cm and a roof structure (measured from center to center of the rafters), a double air scrubber system where a thin air scrubber is mounted inside the elongated body, and a chain stop mechanism mounted in a depression of the handle to operate the air cleaner. Because domestic and industrial workshops generate a substantial amount of sawdust and other foreign materials that are already dispersed in the air, fine dust air purifiers have been developed. This is generally of two types: a mounted unit / console on the floor or a device mounted on the roof / wall. Typical examples of mounted units / floor console are shown in U.S. Pat. Nos. 3,802,168 and 4,894,071 using rollers or wheels to move the fine dust air cleaner to a desired location. An example of an air cleaner device mounted on the ceiling or on the wall is shown in U.S. Pat. No. 3,930,818 where a more permanent type of mounting system is used. Air cleaners with forced air filters and associated blowers are preferred to electrostatic air cleaners because of their lower cost, easier installation and maintenance, and higher capacity. On the other hand, air purifiers that use forced air filters and associated blowers have not been able to process large amounts of highly contaminated air and it has also been difficult to clean and / or replace the filters. As indicated above, the air scrubbers of the prior art have been of the portable or mountable type, but typically have not been of both types. Some users have preferred to move an air cleaner unit to a desired location, while others prefer to mount the air cleaner in a more permanent location. As described in the aforementioned copending patent application, it is possible to provide a self-contained portable / mountable air scrubber that can provide the desired portable and mountable functions. In addition, the construction of the air cleaner, primarily a durable molded plastic, allows the use of a light weight air cleaner that can be moved or lifted easily to be mounted overhead in accordance with the standard weight limits for such activities. In accordance with the present invention, the portable / mountable air scrubber describes an optional mounting bracket system that facilitates installation when mounted on a roof and sized to fit between the typical 40 cm beams in common roof structures. Since this measurement of 40 cm is made from center to center and the standard width of the beam is 7.62 cm, the unit must be less than 33 cm maximum width to fit between these beams. The ability to mount the unit between these beams is beneficial, since it allows greater clarity of head, better utilization of space, which reduces the probabilities obtained in the head caused by running towards the unit. Further, the present invention discloses an integrally improved molded elongated body designed to contain a double filter system that includes a coarse air scrubber and a fine air scrubber that can be easily entered and removed for cleaning. In addition, the present invention discloses a handle with depression containing additional means for activating the appropriate air cleaner to suspend from the ceiling.

BRIEF DESCRIPTION OF THE INVENTION Among the various objects and advantages of the present invention include: the provision of a new and improved portable / mountable air scrubber; providing the aforementioned air cleaner that includes a carrier handle for carrying the air cleaner to a desired location or for mounting the air cleaner on a roof, wall or other structure, as desired; provide the aforementioned air cleaner that can be mounted between the typical 40 cm beams of a roof structure; providing the aforementioned air cleaner that includes an integrally molded elongated body designed to contain a double air scrubber system that includes a coarse air scrubber and a fine air scrubber; providing the aforementioned air cleaner in which the design of the air filters, their position within the elongate body, and the structure of their support within the elongate body are adapted so that both filters can be easily removed and cleaned; providing the aforementioned invention with a pull string to activate the unit and an activation light, both designed to assist in the operation of the unit when suspended from the ceiling.
