PRIORITY STATEMENT 
       [0001]    This application claims priority under 35 U.S.C. §119(e) to provisional U.S. application No. 62/285,002 filed on Dec. 9, 2015, the entire contents of which is incorporated herein by reference in its entirety. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    Field of the Invention 
         [0003]    Example embodiments relate generally to a sprayer, and a sprayer attached to a dual chamber bottle, where the sprayer is capable of selectively discharging two different fluids from the bottle. 
         [0004]    Related Art 
         [0005]    A sprayer may be used to discharge a fluid, such as a chemical, from a bottle. The sprayer may use a vacuum force to draw the fluid from the bottle, where this vacuum force may be created by a working fluid flowing through the sprayer, such that the sprayer may operate as an injector. The sprayer may therefore discharge a mixture of the working fluid and the fluid from the bottle. 
         [0006]    A number of consumer-product applications may benefit from the application and use of more than one fluid and/or chemical. For instance, in the field of consumer automotive products, the application of two or more chemicals, such as a cleaning agent and a spray wax, may be of great value. Other applications (including industrial applications) for surface cleaning, surface preparation, construction, lawn care, painting, manufacturing, etc., may also greatly benefit from the application and use of two or more fluids and/or chemicals. These applications may also benefit from the convenience of spraying these fluids/chemicals onto surfaces and/or objects.

As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises”, “comprising,”, “includes” and/or “including”, when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. 
         [0050]    It should also be noted that in some alternative implementations, the functions/acts noted may occur out of the order noted in the figures. For example, two figures shown in succession may in fact be executed substantially concurrently or may sometimes be executed in the reverse order, depending upon the functionality/acts involved. 
         [0051]      FIG. 1  is an illustration of a perspective view of a dual sprayer  10 , in accordance with an example embodiment. The dual sprayer  10  may be used to discharge more than one fluid and/or chemical, along with a working fluid (such as water). The sprayer  10  may include a major housing  12  with a water inlet end  22  and a sprayer outlet end  16 . The water inlet end  22  may include an adapter  18  that may, for instance, be a quick-connect adapter, or another well-known adapter that allows a water source to be connected to the water inlet end  22 . Specifically, the water inlet end  22  may have an interface  20  that connects to a garden hose (not shown), or another fluid source, allowing the end  22  to accept a pressurized working fluid that may travel through the housing  12  in order to be discharged at the sprayer outlet  16 . 
         [0052]    The sprayer  10  may also include a connector  14  that may attach to a bottle  60  (see  FIG. 3 ). The bottle  60  may, for instance, be a dual chamber bottle that may include two or more separated chambers that may each hold a fluid and/or chemical. More than one suction tube  28  may extend from within the connector  14 , where a distal end of each of the suction tubes  28  may be positioned within one of the chambers of the bottle  60  (as shown in  FIG. 3 ) in order to allow the sprayer  10  to draw fluid from the bottle  60 . One or more physical stops  46  on the connector  14  may be included within an inner surface of the connector  14  in order to attach the sprayer  10  to the bottle  60  (as described in greater detail, herein). 
         [0053]    The sprayer  10  may include a rotating dial  24  that allow the sprayer  10  to be transitioned into different “modes,” as described in more detail in  FIG. 2 . Indicia  32  may be included on the housing  12  in order to signify which mode the sprayer  10  is in. The sprayer may include a handle  30  in order to facilitate easy transport and use of the sprayer  30 , especially in the event that the sprayer  10  is attached to a bottle that may be relatively heavy. 
         [0054]      FIG. 2  is an illustration of an overhead view of the dual sprayer  10  of  FIG. 1 , in accordance with an example embodiment. The rotating dial  24  may include a marker  34  that may be used to indicate which “mode” the sprayer  10  is in. The sprayer  10  may include, for instance, four or more modes (indicated by indicia  32 ), where these modes may be: 1. Off (where the sprayer  10  does not discharge any fluid), 2. A rinse mode (that only discharges the working fluid, which may for instance be water), 3. A “chem 1” mode (where the sprayer  10  may discharge a mixture of the working fluid and a fluid and/or chemical from chamber “A”  60   a  of bottle  60 , as shown in  FIG. 3 ), and 4. A “chem 2” mode (where the sprayer  10  may discharge a mixture of the working fluid and another fluid and/or chemical from chamber “B”  60   b  of bottle  60 , as shown in  FIG. 3 ). These different modes are described in conjunction with the specific structural components of the sprayer  10 , in greater detail below. 
         [0055]      FIG. 3  is an illustration of a cross-sectional side-view of the dual sprayer  10  connected to a dual chamber bottle  60 , in accordance with an example embodiment. In  FIG. 3 , the sprayer  10  is shown in a rinse mode, where only the working fluid  100  is capable of flowing through the sprayer (where the rinse mode is shown in even better detail in conjunction with the discussion of  FIG. 14 ). The sprayer  10  may include a rotatable cylinder  40  that may rotate within a socket (cavity)  42  of the housing  12  of the sprayer  10 . The cylinder  40  may be connected to the rotating dial  24  in order to allow the sprayer  10  to change modes. 
         [0056]    The connector  14  of the sprayer  10  may be a female connector that may be capable of attaching to a male connector  64  of the bottle  60  (as described in more detail herein). Extension tubes  28   a  may be connected to the ends of the suctions tubes  28  in order to allow the sprayer  10  to take suction toward a bottom of the bottle  60 . While the bottle  60  may include a single divider  62  separating the bottle into two chambers (chamber “A”  60   a  and chamber “B”  60   b ), it should be understood that the bottle  60  may also include more than two chambers. 
         [0057]      FIG. 4  is an illustration of a perspective view, from a bottom view, of the dual sprayer  10 , in accordance with an example embodiment. The connector  14  may include, for instance, three physical stops  46  that may be spaced equidistantly around the inner surface of the connector  14 . The physical stops may be beveled, from the standpoint that the stops  46  may be raised, but the stops may become tapered at an end that approaches a distal end of the connector  14 . 
         [0058]    A bottom surface of the housing  12 , that may be above a location of the connector  14 , may include one or more air return ports  47  that may be in fluid communication with one or more air ports  47   b  shown in  FIG. 6 . The air return ports  47  may allow air to enter the bottle  60  as fluid is displaced from the bottle  60  while the sprayer  10  is in functional use. 
         [0059]      FIG. 5A  is an illustration of a male connector  64  at the top of a neck  64   b  of a bottle  60 , such as a dual chamber bottle, in accordance with an example embodiment. The male connector  64  may include two or more depressions  67  that may mate with the beveled stops  46  of the connector  14  of the sprayer  10 . The depressions  67  may include a raised-frame  67   a  capable of retaining the stops  46  with the depressions  67 . 
         [0060]    The male connector  64  may also include a rib  66  positioned along a portion of an outer circumference of the connector  64 . The rib  66  may be positioned to allow one of the physical stops  46  of the connector  14  of the sprayer  10  to slide under the rib  66 , and be retained by the rib  66  (also see the position of the rib in  FIG. 5B ), thereby providing at least three points-of-contact to lock the sprayer connector  14  onto the male connector  64  of the bottle  60 . The rib  66  may have a limited length (discussed below with regard to  FIG. 5B ) in order to allow a physical stop  46  to slide down along an outer surface  64   a  of the bottle connector  64 , and then slide under the rib  66  (and be retained under the rib  66  to impede the connector  14  of the sprayer  10  from separating from the bottle  60 ), such that the connector  14  of the sprayer  10  may only need to be rotated within a limited range of rotation in order to lock the sprayer  10  onto the bottle  60 . In particular, the rib  66  may have a limited length in order to require that the connector  14  of the sprayer  10  may only need to rotate about 30 degrees, or less, as the connector  14  of the sprayer  10  is pressed down onto the connector  64  of the bottle  60  and rotated into a locked position. This limited required angular rotation of the connector  14  on the male connector  64  of the bottle  60  ensures that the suction tubes  28  may be retained on the bottom of the sprayer  10  without being damaged or broken (as a greater required degree of rotation between the connector  14  of the sprayer  10  and the male connector  64  of the bottle  60  may cause the suction tubes  28  to contact the divider  62  and may cause damage to the suction tubes  28 ). 
         [0061]      FIG. 5B  is an illustration of an overhead view of the male connector  64  at the top of  60  dual chamber bottle, in accordance with an example embodiment. Notice that  FIG. 5B  depicts a relative length of rib  66 . In particular, the rib  66  may be positioned to exist along about 20 to 30 degrees of the outer circumference of the male connector  64  (i.e., the rib  66  may extend about 0.35 radians to 0.52 radians along the outer circumference of connector  64 ), in order to limit the required angle of rotation that may be necessary to slip one of the physical stops  46  of the connector  14  of the sprayer  10  under the rib  66  and rotate the connector  14  about 30 degrees or less in order to seat the other physical stops  46  within the depressions  67  and frame  67   a  of the male connector  64  (thereby locking the sprayer  10  onto the top of the bottle  60 ). 
         [0062]    It should be understood that other embodiments have been contemplated, where additional physical stops  46  may be included on the connector  14  of the sprayer, and where additional depressions and/or ribs  66  may be included on a male connector  64  of a bottle. Additionally, it is noted that any of a great variety of bottles may be used, where the dual chamber bottle  60  (shown in  FIG. 3 ) is just one example of a bottle with more than one chamber. Furthermore, while the female connector  14  of the sprayer  10  and the male connector  64  of the bottle  60  have been depicted with a circular cross-section, it should be understood that example embodiments allow for other cross-sectional shapes may instead be implemented. In particular, square or rectangular connectors may be implemented (or, square or rectangular connectors with rounded-corners may be implemented). 
         [0063]      FIG. 6  is an illustration of internals of the main housing  12  of a dual sprayer  10 , in accordance with an example embodiment. The housing may include a socket (chamber)  42  that may contain the rotatable cylinder (valve)  40  of the sprayer  10 . The housing  12  may also include a central passage  50  that may exist between the socket  42  and the inlet end  22  of the sprayer  10  (in order to allow the working fluid to traverse through the inside of the housing  12 ). Near a bottom of the socket  42  (at a location above the connector  14 ), the housing may include air ports  47   b  in fluid communication with the air return ports  47 . The air ports  47   b  may allow air to enter into the bottle  60  while fluid is displaced from the bottle  60  while the sprayer  10  is in use. The bottom of the socket  42  may also include two or more ports, such as a “chemical 1” port  72   b  and “chemical 2” port  74   b , that may allow fluid from the bottle  60  to be drawn into the sprayer  10 . 
         [0064]    An inner surface of the socket  42  may also include ribs  48  that may run longitudinally within the socket  42 . The ribs  48  may support the cylinder  40  (shown in detail in  FIG. 7 ), and allow the cylinder  40  to rotate within the socket  42 . 
         [0065]      FIG. 7  is an illustration of an end-view of the cylinder  40  of the dual sprayer  10 , in accordance with an example embodiment. The cylinder  40  may include a relatively large diameter water discharge line (port)  70  that may run through a longitudinal length of the cylinder  40  and may be in fluid communication with the water discharge tube  80  on the other side of the cylinder  40  (see  FIG. 8 ). This water discharge line  70  may allow the working fluid to pass through the sprayer  10  during a rinse mode. 
         [0066]    The cylinder  40  may also include a relatively smaller diameter “chemical 2” discharge line  74  that may run through a longitudinal length of the cylinder  40  and may be in fluid communication with the “chemical 2” discharge tube  84  on the other side of the cylinder  40  (see  FIG. 8 ). This “chemical 2” discharge line  74  may allow the working fluid to mix with a fluid that may be drawn from a chamber of the bottle  60 . Specifically, the working fluid flowing through the “chemical 2” discharge line  74  may cause a vacuum force within a “chemical 2” suction channel  74   a  that is in fluid communication with the “chemical 2” discharge line  74 , allowing the cylinder  40  to act as an injector in order to draw a fluid from a chamber of the bottle  60  when the “chemical 2” suction channel  74   a  is aligned with the “chemical 2” port  74   b  ( FIG. 6 ) in the “chem 2” mode of the sprayer  10 . In this mode, one or more air return vents  47   a  may also be aligned with the air ports  47   b  in the housing ( FIG. 6 ) in order to allow air to flow into the bottle as a fluid is discharged from the bottle  60 . 
         [0067]    The cylinder  40  may also include a “chemical 1” discharge line  72  in fluid communication with the “chemical 1” discharge tube ( FIG. 8 ), where the function of this line  72  is described in greater detail in association with  FIG. 9 . 
         [0068]      FIG. 8  is an illustration of another end-view of the cylinder  40  of the dual sprayer  10 , in accordance with an example embodiment. Note that this drawing depicts a “chemical 1” suction housing  92  (also shown in  FIG. 13 ). This housing  92  may define the “chemical 1” suction channel  72   a  and the air return vents  47   a  (shown in better detail in  FIG. 9 ). The air return vents  47   a  may be in fluid communication with the air inlet  47   c  of the “chemical 1” suction housing  92  (see  FIG. 13 ) in order to provide a reverse flow-path of air back into the bottle  60  as fluid is discharged from the bottle  60 . 
         [0069]      FIG. 10  is an illustration of an end-view of the cylinder  40  of the dual sprayer  10 , in accordance with an example embodiment. In particular,  FIG. 10  depicts the “chemical 1” suction channel  72   a  that is in fluid communication with the “chemical 1” discharge line  72  that traverses through a longitudinal length of the cylinder  40 . The “chemical 1” discharge line  72  is also in fluid communication with the “chemical 1” discharge tube  82  ( FIG. 11 ). When sprayer  10  is discharging fluid from the bottle  60  through the “chemical 1” discharge line  72 , the cylinder is rotated within the housing  12  so that the “chemical 1” discharge line  72  is aligned with the central passage  50  ( FIG. 6 ). Note that one or more air return vents  47   a  are also near the “chemical 1” suction channel  72   a , as these vents  47   a  may be aligned with the air ports  47   b  of the housing  12  (see  FIG. 6 ) in order to allow a reverse air flow to enter the bottle  60  as fluid is being displaced from the bottle. 
         [0070]      FIG. 11  is an illustration of another end-view of the cylinder  40  of the dual sprayer  10 , in accordance with an example embodiment. This perspective view of the cylinder  40  shows the alignment of a “chemical 1” suction housing  92  with the “chemical 1” suction channel  72   a  and air return vents  47   a  (as both the channel  72  and vents  47   a  are included in the “chemical 1” suction housing  92 ). It should be understood that the air inlet  47   c  shown exiting the “chemical 1” suction housing  92  is in fluid communication with the air return vents  47   a  in order to provide a reverse flow path of air into the bottle  60  as the sprayer  10  displaces fluid from the bottle  60 . 
         [0071]      FIG. 11  also depicts the “chemical 2” suction housing  94  that houses the “chemical 2” suction channel  74   a  and the air return vents  47   a  bracketing the “chemical 2” suction channel  74   a  (shown in  FIG. 9 ). The “chemical 2” suction channel  74   a  is in fluid communication with the “chemical 2” discharge tube  84  (also shown in  FIG. 13 ), whereas the air return vents  47   a  adjacent to the “chemical 2” suction channel  74   a  are in fluid communication with the air inlet  47   c  exiting the “chemical 2” suction housing  94  (as shown in  FIG. 13 ). 
         [0072]      FIG. 12  is an illustration of a side-view of the cylinder  40  of the dual sprayer  10 , in accordance with an example embodiment. In particular,  FIG. 12  depicts the placement of the “chemical 1” suction channel  72   a  and air return vents  47   a  positioned along the side of the cylinder  40 . 
         [0073]      FIG. 13  is an illustration of a discharge end of the dual sprayer, in accordance with an example embodiment. In particular,  FIG. 13  depicts the sprayer  10  in the “off” mode, where the sprayer  10  is unable to discharge either a fluid from the bottle  60 , or a working fluid entering from inlet  22 . This is because neither the water discharge tube  80 , nor the “chemical 1” discharge tube  82  and “chemical 2” discharge tube  84  are aligned with the central passage  50  within the housing (see  FIG. 6 ). 
         [0074]      FIG. 14  is an illustration of a cross-section side-view of the dual sprayer  10  in a “rinse” mode, in accordance with an example embodiment. Notice that in this mode, the water discharge tube  80  of the cylinder  40  is aligned with the central passage  50  (also shown in  FIG. 6 ), thereby allowing a working fluid  100  to enter the inlet  22  of the sprayer and flow through the sprayer  10  to be discharged at the outlet  16 . Notice that in this mode, neither the “chemical 1” suction channel  72   a  nor the “chemical 2” suction channel  74   a  are aligned with the respective “chemical 1”/“chemical 2” ports  72 / 74   b  (also shown in  FIG. 6 ) that would otherwise allow the sprayer  10  to draw fluid from the suction lines  28 . 
         [0075]      FIG. 15  is an illustration of a cross-section side-view of the dual sprayer  10  discharging a first fluid, in accordance with an example embodiment. Specifically, this drawing depicts a “chem 1” mode, where the “chemical 1” suction channel  72   a  may be aligned with the “chemical 1” discharge tube  82 . In this mode, the working fluid  100  may flow through the central passage  50  and the “chemical 1” discharge tube  82 , thereby creating a vacuum force (similar to an injector) that allows a fluid  101  to be drawn through one of the suction lines  28  and through “chemical 1” port  72   b  prior to entering “chemical 1” suction channel  72   a  and mixing with the working fluid  100  before being discharged from the sprayer  10 . Notice that in this mode, at least one air port  47   b  is aligned with at least one air inlet  47   c  in order to allow a reverse flow of air to travel from air return vent  47   a  into the bottle  60  when the sprayer  10  is locked onto the top of a bottle  60  and the sprayer  10  is in use. 
         [0076]      FIG. 16  is an illustration of a cross-section side-view of the dual sprayer  10  discharging a second fluid  103 , in accordance with an example embodiment. Specifically, this drawing depicts a “chem 2” mode, where the “chemical 2” suction channel  74   a  may be aligned with the “chemical 2” discharge tube  84 . In this mode, the working fluid  100  may flow through the central passage  50  and the “chemical 2” discharge tube  84 , thereby creating a vacuum force (similar to an injector) that allows a fluid  103  to be drawn through one of the suction lines  28  and through “chemical 2” port  74   b  prior to entering “chemical 2” suction channel  74   a  and mixing with the working fluid  100  before being discharged from the sprayer  10 . Notice that in this mode, at least one air port  47   b  is aligned with at least one air inlet  47   c  in order to allow a reverse flow of air to travel from air return vent  47   a  into the bottle  60  when the sprayer  10  is locked onto the top of a bottle  60  and the sprayer  10  is in use. 
         [0077]      FIG. 17A  is an illustration of a discharge end of a dual sprayer, in accordance with an example embodiment. This view depicts the sprayer  10  in a “rinse” mode. In this embodiment, a screw  200  may be used to hold the cylinder  40  within the socket (cavity)  42  of the housing  12  of the sprayer  10 . The screw  200  may be positioned to be centrally located within the cylinder  40  in order for the screw  200  to remain stationary as the cylinder  40  may rotate to change modes. 
         [0078]      FIG. 17B  is an illustration of a cross-section side-view of a dual sprayer in a rinse mode, in accordance with an example embodiment. In an embodiment, the socket  42  of the housing  12  may include a cylindrical extension  42   a  that may define a screw-hole  42   b . The screw-hole  42   b  may accept the screw  200 . The screw  200  may remain stationary as while the cylinder  40  is capable of rotating within the socket  42  in order to allow the sprayer  10  to switch between modes. To this end, the cylinder  40  may include a cylindrically-shaped extension  40   a  that may be conformed to the shape of the cylindrical extension  42   a  of the socket  42 . A washer  202  may be positioned between a head of the screw  200  and the cylindrically-shaped extension  40   a  of the cylinder  40  in order to reduce a friction-force between the head of the screw  200  and the distal-end of the extension  40   a . The screw  200  may represent the lone structure that may be capable and necessary to maintain the cylinder  40  within the socket  42  during assembly and during an operational use of the sprayer  10 . A gasket  204  may be fitted between the end of the cylinder  40  and the socket  42  (near the outlet  16 ) in order to reduce potential leakage of the sprayer  10  as the sprayer  10  is in operational use.

Such variations are not to be regarded as a departure from the intended spirit and scope of example embodiments, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
