DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1a-1c illustrates a front view and a side view respectively of an installed evaporative air cooler, according to one embodiment of the present invention. With respect to FIG. 1a and 1b, an evaporative air cooler (100) comprises a water chamber (101) and a fan chamber (102). The water chamber (101) comprises a female locking unit on an upper outer surface. The fan chamber (102) comprises a fan assembly and further comprises a male locking unit (103) and a pump assembly. The male locking unit is locked-in with the female locking unit of the water chamber during an installation of the evaporative air cooler. The pump assembly comprises a pump unit (109) and a position modulator. The packaging shown in FIG. 1c is facilitated to house the water chamber above, below or beside the fan chamber.

The position modulator is variable in assembly structure and connection to the pump unit (109). The assembly structure of the position modulator depends on a design specification of the evaporative air cooler and space available in the fan chamber (101) and water chamber (102).

As shown in FIG. 2 and 2a-2c,The position modulator comprises a fulcrum mechanism further comprises a lever (104) with a first end attached to a hinge (105) connected to an inner body surface of the fan chamber. A second end of the lever is further hinged (106) to the pump unit. The fulcrum mechanism is housed within in the fan assembly during a packaged scenario i.e. when the evaporative air cooler is not being used or transported. The lever of the fulcrum mechanism is released for the movement either manually or after sensing an engagement of the lock between the fan chamber and the water chamber. The releasing of the lever allows an angular displacement of the pump ranging from 0°-180° with respect to the inner body surface of the fan assembly.

According to another embodiment of the present invention, the position modulator comprises a wire connector (107) attached to an inner body surface of the fan chamber (as shown in FIG. 3a and 3b. The wire connector provides a connection between a male port (107a) of the pump unit (109) and a female port (107b) of a main power supply. The pump is optionally stored in the fan chamber or the water chamber during transportation as per a design specification of the evaporative air cooler and a manufacturer preference.

According to another embodiment of the present invention, the position modulator comprises a rack-and-pinion unit (108) hinged to an inner surface of the fan chamber (101) and further connected to the pump unit (109) as shown in FIG. 4a-4c. The rack-and-pinion unit (108) provides an ability to move the pump unit’s (109) position vertically through a manual handling or a control position regulator.

As will be readily apparent to those skilled in the art, the present invention may easily be produced in other specific forms without departing from its essential characteristics. The present embodiments are, therefore, to be considered as merely illustrative and not restrictive, the scope of the invention being indicated by the claims rather than the foregoing description, and all changes which come within therefore intended to be embraced therein.
