Abstract

A spraying device is provided that includes a cartridge containing a first fluid, the cartridge being removably connected to a sprayer body. The cartridge is oriented such that gravity exerts a downward force on the first fluid. The sprayer body includes a conduit for receiving a second fluid. A valve is coupled to the conduit. The valve allows the second fluid to flow through the valve, thus creating a Venturi vacuum that draws the first fluid out of the cartridge and into the valve to enable the first and second fluids to mix and form an outlet stream. An orifice meters a predetermined amount of the first fluid into the valve to achieve a predetermined ratio of the first fluid to the second fluid. The outlet stream is then dispensed from a spray nozzle.

Claims13

Dependent claims

A spraying device cartridge comprising:

a first liquid contained within the spraying device cartridge;
an outlet having a first diameter, configured to be removeably connected to a sprayer body,
an opposite end having a second diameter and located opposite the outlet wherein the opposite end is located in a position above the outlet when the spraying device cartridge is connected to the sprayer body such that gravity exerts a downward force on the first liquid to pull the first liquid towards the outlet;
the outlet comprising a first set of external threads, and defining a fluid flow path for the first liquid, wherein a downstream direction is towards the outlet and an upstream direction is towards the opposite end;
and
a check valve comprising a duckbill portion and an umbrella portion mounted in the outlet, the duckbill portion comprising a path for the first liquid to flow through from the spraying device cartridge and the umbrella portion comprising an air flow path for venting of the spraying device cartridge.
