- the cartridge has inlet and outlet openings that are both located on the same end of the purifier cartridge, the end inserted into the sprayer housing 22.
- water flows in the inlet opening into first cylindrical portion 42. Water then flows from the first cylindrical portion 42 through a channel 46 connecting the first and second cylindrical portions, to the second cylindrical portion 44. Water exits the purifier cartridge 34 at the outlet opening into a purified rinse spray conduit.
- the inner valve component 58 has a top surface 80 with an opening 82 therein, and several depressions 84 therein.
- the opening 82 permits water from the hose to flow through the valve 50.
- the selector inner seal 64 sits on top of the selector spring 62, and fits at least partially into the opening 82 in the top surface 80 of the inner valve component 58.
- the top surface 80 of the inner valve component 58 may also comprise one or more seals 86.
- the seals 86 can be of any suitable configuration. In the embodiment shown, the seals 86 are in the form of raised ribs that radiate outward from the center of the top surface 80 of the inner valve component 58.
- the seals 86 can have any other suitable configuration.
- the seals can be located on the underside of the top valve component instead of, or in addition to, being located on the top surface 80 of the inner valve component 58.
- the top valve component 60 comprises a plate 87 and a pair of inflow conduits 88 and 90.
- One of the inflow conduits directs incoming water that passes through the valve 50 to a conduit that by-passes the water purifier 34, and thus comprises the rinse conduit.
- the other inflow conduit directs incoming water that passes through the valve 50 into the water purifier 34.
- the purified water then flows out of the purifier in a conduit that leads to a purified rinse spray nozzle.
- the click pin 68 fits over the click spring 66, and the click spring is inserted into the underside of the top valve component 60.
- the top valve component 60 then rides on top of the inner valve component 58 to complete the assembly of the valve 50.
- FIG. 7 shows the selector switch 36 and the valve system turned to one side.
- the opening 82 in the top surface 80 of the inner valve component 58 aligns with one of the inflow conduits 88 and 90 of the top valve component 60, and water will flow through the valve 50 into the inflow conduit.
- the click pin 68 engages into the depression 84 to the left of the central depression on the top surface 80 of the inner valve component 58 to provide a signal to the operator that the selector switch 36 is in a different position.
- the selector switch 36 in one non-limiting embodiment, has at least two positions. In the embodiment shown, the selector switch 36 has three positions, which are from left to right: "tap water spray", "off, and "purified rinse".
- the multiple position selector switch 36 can be controlled by one of the operator's fingers, or by the operator's thumb, so that the operator can use the sprayer and select the sprayer setting with one hand. This will allow the operator to use their other hand for some other task, such as during a process of washing a vehicle, applying a cleaning composition to the surface of the vehicle. Alternatively, this may allow the operator to hold some article in their other hand, such as a cleaning mitt, or other cleaning implement.
- FIG. 8 shows an alternative embodiment of a selector switch.
- the selector switch 36 is a thumb switch. The operator can control this switch by applying force on either side of the switch with their thumb.
- Other embodiments of this switch can also be provided that have differents widths to provide different "throw" distances when changing from one switch setting to another setting.
- the selector switch 36 can have any other suitable configuration.
- the sprayer could be of the type described in U.S. Patent Application Serial No. 10/137,748 filed on May 2, 2002, and published as US 2003/0034051 Al on February 20, 2003, or in the configuration of the sprayer shown in U.S. Design Patent Application Serial No. 29/193,107 filed on November 3, 2003.
