[0029] Referring now to FIGS. 1-2, a side cross-sectional view (FIG. 1) and a side view (FIG. 2) of a liquid sprayer head 10 are illustratively depicted.

[0030] According to various embodiments, the sprayer head 10 includes a spray reservoir configured to store liquid to be sprayed through a nozzle 20 via a channel 25. The sprayer head further includes an internal liquid dispenser 30 and reservoir 35. Additionally, the sprayer head includes a trigger 40 configured to facilitate movement of liquid into the spray reservoir 15 and movement of liquid from the spray reservoir 15 through the nozzle 20 via channel 25.

[0031] The trigger 40 is configured to move between a pulled (first) position and a released (second) position. In the embodiment shown in FIGS. 1-2, the trigger 40 is in the released position. In the pulled position, the trigger 40 rotates around a rotation point or hinge 45, applying pressure to the spray reservoir 15 decreasing the interior volume of the spray reservoir 15. For example, the trigger 40 may include a protrusion 50 configured to enter the spray reservoir 15 and/or cause a plunger or other suitable device to enter the spray reservoir 15, decreasing the interior volume of the spray reservoir 15.

[0032] When liquid is within the spray reservoir while the trigger 40 is in the released position, when the trigger 40 is engaged and moved from the released position to the pulled position, the liquid in the spray reservoir 15 is forced from the spray reservoir 15, through a channel and exterior from the spray head 10 via the nozzle 20. According to various embodiments, the nozzle 20 can include one or more holes of equal or varying size, configured to cause the liquid to escape from the spray head at a desired velocity.

[0033] According to various embodiments, the trigger 40 includes a biasing force (via, e.g., a spring or other suitable biasing member) configured to bias the trigger 40 from the pulled position to the released position upon removal of an external pressure from the trigger 40 (e.g., via the hand of a user). When the trigger 40 is released, the biasing member causes the trigger 40 to return the released position, increasing the internal volume of the spray reservoir 15. This increase in internal volume of the spray reservoir 15 results in a vacuum suction force within the spray reservoir 15, causing liquid to be sucked into the spray reservoir 15 through channel 55, from an exterior reservoir (not shown), and from the internal liquid reservoir 35. With the application of the vacuum suction force, liquid is pulled into the spray reservoir 15 from a plurality of sources.

[0034] Liquid enters the spray reservoir 15 from the exterior reservoir, through a channel and into the spray reservoir 15. According to various embodiments, the spray reservoir 15 is coupled to the spray reservoir 15 via a one-way valve, enabling liquid to be sucked through the one-way valve with the application of the vacuum suction force within the spray reservoir 15, but prevents movement through the channel from the spray reservoir 15. According to various embodiments, the trigger is configured to cause an approximate volume of liquid to pass through the channel 55 into the spray reservoir 15 when the trigger 40 moves from the pulled position to the released position.

[0035] According to various embodiments, the spray head 10 includes an internal liquid reservoir 35 and dispenser 30 (shown in more detail in FIGS. 3A-3B). The internal liquid reservoir and dispenser 30 are housed within the spray head 10. In some embodiments, the spray head includes an outer housing and the internal liquid reservoir 35 and dispenser 30 are housed within the housing.

[0036] When the trigger 40 moves from the pulled position to the released position, the vacuum suction force causes a portion of the liquid within the internal reservoir 35 to be sucked through a channel 60 to the dispensing mechanism 30 and into the spray reservoir 15.

[0037] As shown in FIGS. 6A-6B, the internal reservoir 35 includes a storage chamber 70 for storing the liquid within the internal reservoir 35 and a port 65 through which the liquid moves from the storage chamber 70 to the channel 60. According to various embodiments, the channel is a component of a measured liquid intake mechanism 75 (shown in more detail in FIGS. 5A-configured to enable a measured volume of liquid to be sucked into the spray reservoir 15 from the internal liquid reservoir 35 when the trigger 40 moves from the pulled position to the released position. According to various embodiments, the measured volume results in a ratio in the spray reservoir of liquid form the internal reservoir 35 to liquid from the exterior reservoir (not shown). According to various embodiments, the ratio varies based on the concentration of the liquid in the internal reservoir 35 and the liquid in the exterior reservoir.

[0038] According to various embodiments, the channel 60 includes an opening 80 configured to limit the rate of flow of the liquid moving from the internal liquid reservoir 35 to the spray reservoir 15. According to some embodiments, the opening 80 has a smaller diameter than the channel 60. According to some embodiments, the internal liquid reservoir 35 includes a vent valve 90 for enabling air to enter into the internal liquid reservoir 35 as the liquid exits the internal liquid reservoir 35.

[0039] According to various embodiments, the ratio is affected by the diameter of the opening 80. According to various embodiments, the diameter of the opening 80 is approximately mm. It is noted, however, that other diameters may be implemented (e.g., between 0.2 and 1.0 mm, or greater), while still maintaining the spirit and functionality of the present disclosure.

[0040] According to various embodiments, the measured liquid intake mechanism 75 is configured to dispense a volume of liquid from the internal liquid reservoir 35 pertaining to a range of mass per liquid volume dispensed from the exterior reservoir. For example, the ratio may be approximately 0.025-0.15 grams per fluid ounce of liquid from the exterior reservoir. It is noted, however, that other ratios may be implemented, depending on the properties of the fluid within the internal liquid reservoir 35 and the fluid within the exterior reservoir.

[0041] As shown in FIGS. 1 and 3A-3B, and in more detail in FIGS. 4A-4B, the spray head includes an internal liquid dispenser 30 configured to transfer liquid from channel 60 to the spray reservoir 15. According to various embodiments, the internal liquid dispenser 30 includes a one-way valve 95 which enables liquid to be sucked into the spray reservoir 15 via the channel 60, but not to be pushed through the channel 60 from the spray reservoir 15. According to various embodiments, the one-way valve 95 is a ball valve. It is noted, however, that other suitable one-way valves may be used, while maintaining the spirit and functionality of the present disclosure.

[0042] According to various embodiments, the internal liquid reservoir 35 is configured to hold a liquid to be mixed with the liquid from the exterior reservoir prior to the mixture being expelled form the spray head 10 view the nozzle 20. For example, the internal liquid reservoir 35 may contain a perfume or deodorizer. If the liquid from the exterior liquid reservoir has an undesired or foul odor, the perfume or deodorizer can be mixed in with the liquid from the exterior liquid reservoir prior to spraying the liquid, decreasing or masking the odor form the exterior liquid reservoir. Additionally, since the internal liquid reservoir 35 is housed within the spray head 10, the spray head 10 can be switched from bottle to bottle (or other suitable exterior liquid reservoir) while maintaining the liquid within the internal liquid reservoir 35 between movements of the spray head 10.

[0043] The features and functions described above, as well as alternatives, may be combined into many other different systems or applications. Various alternatives, modifications, variations, or improvements may be made by those skilled in the art, each of which is also intended to be encompassed by the disclosed embodiments.
