Claim:
An automatic spraying device comprising: a housing with a removable front section in which there is an opening; an aerosol spray canister removably held within the housing on a platform; the housing having a location section in which a spray head of the spray canister is located, the location section having a neck section in which an inlet section of the spray head is received; an actuator arm located above the spray head which is moveable by an electrically powered actuator to move down into the location section and onto the spray head to cause activation of the aerosol spray canister to spray material from the canister through the opening; the spray head further comprising: the inlet section having a generally oval-cross section and further having an opening in the inlet section adapted to receive an output section of the spray material canister, said opening forming a first end of a fluid channel for spray material from the spray material canister, the channel comprises a bend which diverts the direction of the fluid channel, which defines a first part of the fluid channel which extends from the opening to the bend; and an outlet section adapted to eject spray material and forming a second end of the fluid channel for spray material which includes a horizontal section, and a further channel extending from the bend to a mouth section at an end of the horizontal section, which defines a second part of the fluid channel, and wherein the length of the second part of the fluid channel is greater than the length of the first part of the fluid channel; the inlet section has a first, major, lateral axis and a second, minor, lateral axis, said first and second axes being substantially at right angles to one another; and wherein a distance between the sidewall of the inlet section along the first, major, axis is greater than a distance between the sidewall of the inlet section along the second, minor, axis; and, a location block located axially above the inlet section and said location block being wider than the inlet section along the second, minor, lateral axis and said location block being wider than the neck section of the location section of the device.
