Apparatuses for ventilating and deodorizing air

Abstract

To accomplish the task of removing foul air, the malodor ventilation apparatus has attachment members such as suction cups or a hook for easy installation in different locations. The apparatus has an inlet port for the intake of objectionable air and an outlet port to expel scented refreshed air. Air is drawn into the inlet port by a motorized fan that creates a pressure differential. The objectionable air is drawn through a porous filter. The porous filter is scented by several drops of a liquid scent. This scent is volatized into the malodorous air, changing the air into a pleasing aroma. The scented air is expelled and dissipated through an outlet port of the apparatus. Alternately, the apparatus can comprise a vent duct coupled to exhaust air from the outlet port.

1 . An apparatus for ventilating malodorous air and capable of being supported by an object, the apparatus comprising: 
 a casing defining an inlet port and an outlet port;    at least one element for removably attaching the casing to the object;    a motorized fan creating a partial vacuum that draws the air into the inlet port and exhausts the air from the outlet port; and    an inlet nozzle member coupled to the casing and defining a passage with a relatively wide opening meeting with the inlet port of the casing and a relatively narrow opening opposite the relatively wide opening.    
   
   
       2 . An apparatus as claimed in  claim 1  further comprising: an energy source coupled to the motorized fan.  
   
   
       3 . An apparatus as claimed in  claim 1  wherein the energy source comprises a battery.  
   
   
       4 . An apparatus as claimed in  claim 1  wherein the energy source comprises a transformer coupled to receive power from a wall outlet.  
   
   
       5 . An apparatus as claimed in  claim 1  wherein the motorized fan is adaptable to selectively receive power from a battery housed within the casing or a wall outlet.  
   
   
       6 . An apparatus as claimed in  claim 1  further comprising: a timed duration control unit coupled to the motorized fan, and controllable to activate the motorized fan for a period of time.  
   
   
       7 . An apparatus as claimed in  claim 6  further comprising: a switch coupled to the timed duration control unit, for activating the timed duration control unit to operate the motorized fan.  
   
   
       8 . An apparatus as claimed in  claim 6  wherein the switch comprises a motion sensor that activates the timed duration control unit to operate the motorized fan, based on movement of a living body in proximity to the object.  
   
   
       9 . An apparatus as claimed in  claim 6  wherein the switch comprises a heat sensor that activates the timed duration control circuit to operated the motorized fan, based on heat of a living body.  
   
   
       10 . An apparatus as claimed in  claim 6  wherein the switch comprises a pressure sensor for activation of the timed duration control unit to operate the motorized fan, based on weight of a person's body.  
   
   
       11 . An apparatus as claimed in  claim 6  wherein the switch can be manipulated by a person to activate the timed duration control unit to operate the motorized fan.  
   
   
       12 . An apparatus as claimed in  claim 6  wherein the timed duration control unit is functional to provide the energy source from an internal or external energy source.  
   
   
       13 . An apparatus as claimed in  claim 6  further comprising: an element coupled to the switch, for removably attaching the switch to the object.  
   
   
       14 . An apparatus as claimed in  claim 13  wherein the object comprises a toilet stand.  
   
   
       15 . An apparatus as claimed in  claim 13  wherein the object comprises a waste disposal can.  
   
   
       16 . An apparatus as claimed in  claim 13  wherein the object comprises a cat litter box.  
   
   
       17 . An apparatus as claimed in  claim 1  further comprising: a porous filter situated with respect to the casing so as to receive air from the inlet port; and a liquid fragrance for application to the porous filter, for treating the air from the inlet port so as to be fragrant upon passing through the filter.  
   
   
       18 . An apparatus as claimed in  claim 1  wherein the element coupled to the casing comprises a suction cup.  
   
   
       19 . An apparatus as claimed in  claim 1  further comprising: a conduit having a first end coupled to the inlet nozzle member at its relatively narrow opening; an intake member coupled to a second end of the conduit; and at least one element coupled to the intake member, for removably attaching the intake member to the object.  
   
   
       53 . An apparatus as claimed in  claim 19  wherein the conduit comprises a flexible hose.  
   
   
       20 . An apparatus as claimed in  claim 19  wherein the inlet nozzle member is removable from the casing.  
   
   
       21 . An apparatus as claimed in  claim 19  wherein the element for attaching the casing to the object comprises at least one suction cup.
