Switch frame electronic air filter alarming device
First Claim
1. An alarm apparatus for use with an air filter, said apparatus comprising:
- a filament stretched across at least one portion of an air filter frame of said air filter, wherein said at least one portion comprises a first locus and a second locus located opposite said first locus, such that said filament is attached at a first end of said filament to said air filter frame at said first locus;
a switch attached to a second end of said filament, said switch mounted to said air filter at said second locus of said at least one portion of said air filter frame; and
an alarm that communicates with said switch, such that when said air filter becomes loaded with debris, said air filter deflects thereby causing a force to be exerted on said filament, which in turn triggers said switch to transmit a signal to said alarm indicating that said air filter requires proper attention thereof.

Abstract
An alarming apparatus and methods for use with an air filter are disclosed herein. A filament can be stretched across a portion or section of an air filter frame, wherein the portion or section comprises a first locus and a second locus located diagonally opposite the first locus. The filament can be attached at a first end of the filament to the air filter frame at the first locus. A micro-switch can be attached to a second end of the filament at the second locus. Additionally, an alarm can communicate through a communications device (wired and/or wireless) with the micro-switch, such that when the air filter becomes loaded with debris, the air filter deflects thereby causing a force to be exerted on the filament, which in turn triggers the micro-switch to transmit a signal to the alarm indicating that the air filter requires proper attention thereof. The filament can be stretched facing either an upstream or a downstream side of airflow thereof.

9. An alarming apparatus for an air filter, said apparatus comprising:
-
a filament stretched across at least one section of an air filter frame of said air filter, wherein said at least one section comprises a first corner and a second corner located diagonally opposite said first corner, such that said filament is attached at a first end of said filament to said air filter frame at said first corner;
a micro-switch attached to a second end of said filament and mounted at said second corner of said at least one section of said air filter frame, wherein said micro-switch is electrically connected to a wire which is connected to a communications device; and
an alarm that communicates with said communications device, such that when said air filter becomes loaded with debris, said air filter deflects thereby causing a force to be exerted on said filament, which in turn triggers said micro-switch to transmit a signal to said alarm indicating that said air filter requires proper attention thereof. - View Dependent Claims (10)

11. An alarm method for providing an alarm associated with an air filter, said method comprising the steps of:
-
stretching a filament across at least one portion of an air filter frame of said air filter, wherein said at least one portion comprises a first locus and a second locus located opposite said first locus, such that said filament is attached at a first end of said filament to said air filter frame at said first locus;
attaching a switch to a second end of said filament at said second locus of said at least one portion of said air filter frame; and
automatically triggering said switch to transmit a signal to an alarm indicating that said air filter requires proper attention thereof, when said air filter becomes loaded with debris, said air filter deflects thereby causing a force to be exerted on said filament. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
