Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of provisional application serial number 63 / 475,717 filed by the inventor on December 3, 2022. Background Art

[0003] The spout of a bathroom faucet is usually actuated by a handle. Currently, handleless faucets are mainly found in restrooms at airports and other places. These handleless faucets are used to significantly reduce the spread of infectious diseases, which can have a devastating impact on human well-being, among other possibilities. These faucets are uneconomical for most people and require maintenance by trained technicians for reliable and substantially continuous and expected timely operation. In addition, such faucets have a shorter service life compared to manually operated faucets.

[0004] Conventional manually operated faucets in homes are usually equipped with cartridge valves that require a handle for their actuation; therefore, everyone in a home or school or location that uses a faucet with a handle is exposed to infections from handle-enabled faucets. Currently, handle-enabled faucets require turning a lever through a right angle handle to activate, yet the spout is arranged separate from the handle, because with current faucets, water can be made to flow by turning the lever handle through at most a right angle.

[0005] Actuating the lever may contaminate the lever handle with pathogens. For example, after the hands are washed, those same hands are again used to actuate the lever to shut off the water flow, and thus the hands or other parts of the body may again be contaminated with residual pathogens that were originally left on the lever before the hands were washed. Current faucets are not designed to clean the lever or dispense detergent or antimicrobial solutions when the faucet lever is actuated.

[0006] There are many designs of manually operated faucet valves; however, there is a need for a manually operated faucet that can achieve a lever-washable detergent dispensing capability. Furthermore, such a lever-washable detergent dispensing faucet should be affordable for economic and human health reasons. Furthermore, the design of such a lever-washable detergent dispensing faucet valve should conform to innovative modern faucet design features.

[0007] In addition, the advent of globalization has facilitated the rapid spread of diseases that can significantly affect world health and economies on a large scale; such diseases were previously localized and therefore did not pose a threat to the global economy or human well-being. It is conceivable that unknown pathogens exist, and at this point in global human development and beyond, there will always be the threat of life-threatening pathogens.

[0008] Electronic eye faucets or handleless faucets are available, for example, as seen in U.S. Pat. No. 4,767,922 to Stauffer, entitled Hand Presence Activated Water Faucet Controller, or in U.S. Pat. No. 9,347,207 to Chen, entitled Faucet Assembly. However, these known faucets are generally not affordable to the global population. Therefore, a faucet system inherently makes lever-controlled showering possible while being affordable, thereby mitigating the spread of pathogens in schools, homes, and other institutions and facilities where people share the use of faucets.

[0009] Furthermore, by integrating a lever-actuated soap dispenser with a washable lever, a significant reduction in pathogen transmission can be achieved. Summary of the invention

[0010] In accordance with embodiments of the disclosed subject matter, the present invention provides greater protection against the spread of pathogens, such as Covid-19, H1N1, influenza, and other transmissible pathogens, and preferably includes a valve cartridge that operates effectively while dispensing detergent and enables the lever handle to be cleaned as the hands are washed.

[0011] The present invention includes a valve stem assembly that functions to enable the lever handle to be cleaned by water flowing from the spout of a bathroom faucet, the bathroom faucet preferably utilizing a valve cartridge; this is achieved by appropriately determining the length of the lever relative to the positioning of the spout and the faucet cartridge of the present invention, thereby enabling the lever to intercept the water flow line from the spout of the faucet using a preferably cartridge valve. The valve stem also activates a detergent dispensing unit to dispense detergent from the detergent dispensing unit, while being able to reduce the flow rate of the solvent through the spout of the faucet unit when the lever is rotated to its maximum predetermined angle. The stability of the valve stem can also be achieved by applying a valve cover nut that stabilizes the valve stem to a cartridge assembly seat. Embodiments of the present invention enable detergent to be dispensed before the water from the faucet spout when the lever is initially rotated, or when water flows from the spout of the faucet as the lever rotates, detergent can be dispensed during the timely rotation of the lever.

[0012] A faucet assembly may have at least one valve cartridge, the assembly comprising: a faucet having at least one faucet handle; a fluid conduit affected by the faucet handle for actuating a cartridge valve; a faucet body having an outlet or spout for releasing fluid at an outlet end and an inlet end in fluid communication with the fluid conduit; a base for mounting the faucet handle and the faucet body; the base having an upper surface and at least one cartridge, the at least one cartridge comprising a cartridge body having an outer surface, an inner surface defining a longitudinally extending channel extending from an inlet opening to an outlet opening, and at least one side opening extending laterally from the inner surface through the body to the outer surface.

[0013] The valve stem of the barrel unit can utilize an upper end portion and a lower end portion. The upper end portion of the valve stem can utilize a device to react to the rotation of the control rod to rotate. The upper end portion can further be realized by a device for starting the detergent dispensing unit and can also be realized by attachments, which can limit the rotation of the rod to its predetermined maximum rotation angle. When the valve stem member is located in the passage of the body, the upper end portion extends outward beyond the outlet opening of the body. The lower end portion is cylindrical and is configured to be assembled with the inner surface of the body in a rotatable relationship when located in the passage of the body. In addition, the lower portion has a bottom surface configured to contact and interact with the upper surface of the movable disk. The geometric sidewall of the lower portion is configured to be assembled in the passage of the body and to define at least one fluid receiving area with the inner surface of the body in a rotatable mirror relationship and with the sidewall portion extending inward, wherein the receiving area is configured so that it can be rotated to align with the side opening in the body to allow fluid to flow out of the side opening of the body.

[0014] The fluid receiving area is slightly parabolic in character and is defined by the surface of the retaining disk, the lower surface of the valve stem and one of the barrel body sidewall openings.

[0015] a receiving area configured so that it can be rotated to align with a side opening in the body so as to allow fluid to flow out of the side opening of the body; a fixed disc having at least one opening, but preferably two symmetrically arranged therein, so as to allow fluid to pass from the inlet opening of the body through the side opening of the body when the opening in the fixed disc is aligned with the fluid receiving area in the movable disc, the fixed disc having a side wall capable of interacting with the inner surface of the body; and a sealing ring for stabilizing and retaining the fixed disc and the movable disc within the channel of the body, the sealing ring being designed with tolerances that enable the sealing ring to simultaneously match the body but ensure stability and reliability of stresses interacting with its function.

[0016] The outer surface of the body preferably includes at least one sealing groove for receiving a sealing member (such as an O-ring). The outer surface of the body can also enable a device for placing the valve cartridge in or on a fluid conduit; for example, the feature can be a locking lug and the body can include two diameter locking lugs thereon. The upper surface of the barrel body can be implemented with a device for limiting the rotational movement of the valve cartridge when in use; for example, there can be two raised, preferably rectangular prism-shaped stop features on the circle of the upper surface of the body. The position of the raised stop is characterized by the function of limiting the rotation of the control rod to its maximum predetermined rotation angle. The lower end portion of the valve stem can have a groove on the outer portion, which is used to receive a seal, such as an O-ring, between the inner surface of the body and the lower end portion of the valve stem. The inner surface of the barrel body can also enable a groove near the inlet end of the body, which is used to receive a sealing ring, such as an O-ring. The sealing ring can be configured by silicone, nitrile rubber, fluoroelastomer or other suitable joint sealing interventions.

[0017] The fixed disk and the movable disk are preferably configured from ceramic.

[0018] The valve stem is preferably made of metal, preferably stainless steel or brass. The body can be configured of metal such as brass, stainless steel, copper, nickel, alloy metal, polymer or hard rubber such as polyether ketone, polymethylene copolymer or another compatible suitable composite material. The upper end barrel body is preferably made of copper, brass, stainless steel. The control rod handle is preferably configured of stainless steel.

[0019] The cartridge body preferably has two side openings and the fixed disc preferably has two openings for allowing water to pass from the inlet opening of the body and then through the side openings of the body when the openings in the fixed disc are aligned with the fluid receiving area in the movable disc.

[0020] Preferably, there are two fluid receiving areas in the movable disc, and the fixed disc enables a locking mechanism that can be mated with a mating groove on the outer surface of the body, thereby ensuring limited rotational movement. The preferred two openings on the fixed disc are further aligned relative to each other to accommodate the function of the lever assembly; the function of the lever assembly is to ensure that the lever can be enabled for cleaning while ensuring convenient positioning of the lever relative to the function and positioning of the faucet part when not in use.

[0021] The relationship distance between the base of the faucet spout and the base of the spindle handle a, the distance between the vertical line of fluid flow from the faucet spout and the base of the spout b, and the distance be between the vertical line of fluid flow and the base of the faucet handle c satisfy the following relationship:

[0022] The washable control rod handle initiates the flow of solvent by rotation of the actuating spindle, whereby a cam attached to the upper end of the valve stem will rotate when the control rod is rotated, whereby by attaching a cam to the control rod, wherein such cam affects a follower connected to a piston, wherein the piston serves as an extension-retraction actuation unit for dispensing detergent, a significant reduction in pathogen transmission can be achieved.

The detergent reservoir 450 and the spout escutcheon 977 are arranged in a manner similar to the embodiment of the present invention. Figure 2 The control rod 20 is preferably made of brass or stainless steel.

[0154] See also Figure 3 , shown is from Figure 2 The view from the right side. Line 777 shows the vertical flow direction of the fluid from the faucet spout portion 8 of the spout 10 on the faucet assembly. The horizontal distance 24 (marked as b) between the line 444 and the line 777 and in the plane containing the line 444 and the line 777 makes the vertical line 555 protrude in the plane between the line 444 and the line 777 and in the plane containing the line 444 and the line 777, and wherein the line 555 is a vertical line of the axis 555 of the cartridge unit 420.

[0155] See also Figure 4 and Figure 2 , the geometric length 26 of the handlebar 20, which is denoted by c, can be determined by the inequality is related to the geometric distance a and the geometric distance b, when the relationship When present in the faucet, the control lever handle 20 can be enabled to intersect the fluid flow line 777 from the spout portion 8 of the spout 10 of the faucet; therefore, the control lever portion 20 can be exposed to interact with the fluid flowing out of the spout portion 8 of the spout 10.

[0156] See also Figure 5 , shown is the geometric configuration of a single lever faucet unit.

[0157] See also Figure 6 , shown is an embodiment of the cartridge unit 420. Figure 7 , which shows the exploded parts of the barrel unit 420. Figure 6 As shown, the cartridge 420 includes a body 90 having an exterior surface 64 and an interior passage 68 . Figure 8 shows the configuration of the body 90, and Figure 8a FIG. 9 shows the configuration of the cross section of the body 90. Figure 8 As shown in , the outer surface is preferably generally cylindrical in shape so as to be easily located in a flow conduit for fluid and thus enable an inline valve to be operated between the conduit and the outlet of the faucet. The body can be formed of a variety of materials such as metals, metal alloys or other practically compatible economical non-metallic composite materials or thermoplastics, etc.

[0158] The internal passage 68 of the body 90 defines a passage 68 extending longitudinally through the body, such as Figure 8a As shown. The passage 68 preferably extends from an inlet opening 70 at the bottom of the body to a lateral outlet opening 82 at the top of the body. The passage 68 preferably has a cylindrical configuration that facilitates the use of rotating components therein, and may also have one or more sections or multiple sections to accommodate the sizes and shapes of various components therein. As shown, the passage has an upper portion 76 and a lower wider cross-sectional diameter portion 78, the upper portion 76 preferably having a diameter as shown. Figure 8a The narrower cross-sectional diameter is shown to correspond to the size of region 57 of the valve stem 104, and the lower wider cross-sectional diameter portion 78 is preferably wider to accommodate other components of the valve, such as a disk, sealing ring, and a rotatable base portion of the valve stem 104.

[0159] The body further includes at least one side opening 82 extending laterally through the body from the interior passage 68 to the exterior surface of the body 90. The side opening 82 is preferably positioned to be consistent with current faucet designs because water or other fluid flowing upward through the inlet end 70 of the body into the passage 68 will encounter the fixed disk and pass through the opening therein when in the open valve mode until it enters the receiving area of ​​the movable disk and can then flow out of the side opening 82 in the body to continue supplying the faucet body and the outlet of the faucet.

[0160] Therefore, the one or more side openings 82 for this embodiment should preferably be positioned to accommodate those side openings that flow out of the side openings 82 in an unimpeded manner within the design. For fluid flow characteristics, the openings are preferably rectangular, but may have other configurations. As shown, two such side openings 82 are shown, which are compatible with the number of openings and receiving areas in the disc.

[0161] The openings 82 are preferably rectangular for fluid flow features, but may have other configurations. As shown, two such side openings 82 are shown, which are compatible with the number of openings and receiving areas in the disc.

[0162] Fig. 9 The configuration of the body stop interceptor member 205 is shown, and Fig.10 A cross section of the component 205 is shown.

[0163] See also Figure 8 , the body 90 has an upper generally flat surface 130 which can have means for limiting the rotation of the handle 20 and thus the valve stem 104. The means for limiting the rotation of the valve stem 104 are realized by raised features 60 and 61, wherein the features 60 and 61 are designed to limit the rotation of the valve stem 104 by the control lever 20 to a maximum predetermined rotation angle; such limitation can be achieved when the stops 60 and 61 are rigidly connected to the upper surface 130 of the cartridge body 90. As will be shown, the maximum predetermined rotation angle limits the range of movement of the opening of the movable disc 102 against the fixed disc 112 and thus enables the desired coordination of the various flow openings to be achieved within a certain predetermined rotation range. Fig.15 An embodiment of such a removable disk is shown in Fig.16 An embodiment of such a fixed disk is shown in FIG. The stop feature 60 and the stop feature 61 are enabled on the upper surface 130 and are arranged so that the center of the circle is located on the rotation axis of the valve stem portion 57, and the stop feature positions 60, 61 can represent multiple endpoints on spaced radii, wherein the radius originates from a common point in the plane of the surface 130 located on the rotation axis of the valve stem portion 57.

[0164] See also Fig.10 , Fig. 9 The inner flange 47 of the bonnet nut 205 shown in FIG. contacts the outer region of the body surface portion 130. The access region opening 45 of the bonnet nut 205 fits with and surrounds the region 59 of the valve stem 104; however, the access opening 45 of the bonnet nut 205 is able to rotate substantially freely around the region 59 of the valve stem 104. The bonnet nut 205 fully accommodates the passive stops 60, 61 and the active stop 404 so that there is a measurable distance between the inner regions of the bonnet nut 205, the passive stops 60, 61 and the active stop 404, thereby stabilizing the valve stem 104 when the active stop 404 is fitted with the region 56 of the stem 104. The member 65 of the active stop 404 interacts with the static stops 60, 61 to substantially allow a maximum predetermined rotation angle of the valve stem 104. The bonnet nut 205 is used to ensure the stability of the valve stem 104 and, by extension, ensures a stabilizing function of the cartridge unit 604 .

[0165] See also Fig.14 , shown is a cartridge unit member 104, which is commonly referred to as a valve stem of a ceramic faucet unit. The valve stem 104 includes a reduced cylindrical diameter region 57 of the valve stem member 104. An upper region 58 of the region 57 is adjacent to a lower region 52 of the region 57. The region 58 is configured to Fig.12 The control lever handle unit 304 is in a rotatable relationship, and the region 52 will be shown as being configured with Fig.39 The dragon head system components are shown in a rotatable relationship.

[0167] Region 56 of region 57 adjoins region 59 . Fig.14 The area 56 is configured with Fig.13 The inner portion 34 of 404 is depicted in a rotatable relationship.

[0168] See also Fig.13 , the faucet unit member 404 is used to interact with the body stops 60, 61 when assembled with the area 56 of the upper stem portion 57. The member 65 of the member 404 will be shown to interact with the body stop 61 and the body stop 60, and will also be shown to achieve a predetermined angular rotation of the area 57 and thus ensure the rotation of the movable disc 102 through the valve stem 104.

[0169] See also Fig.12 , when the valve stem 104 is in a locked relationship with the control rod unit 304, the portion 58 of the valve stem 104 enables the valve stem 104 to rotate; this locking means between the outer region 58 of the region 57 of the valve stem 104 and the inner portion 34 of the control rod unit 304 can be achieved by a groove lock between the region 58 of the portion 57 and the inner wall of the circular groove 34 of the valve stem 304. The inner wall 34 of the cam member 410 is also grooved for locking means with the region 52 of the region 57 of the valve stem 104, while the inner portion 34 of the valve stem 104 is grooved for locking means with the region 55 of the region 57 of the valve stem 104. The region 59 of the region 57 is substantially smooth and enables rotation of the inner surface 45 of the valve stem 205 to move substantially frictionlessly on the surface 59 of the region 57. Fig. 9 shows the configuration of the component 205, and Fig.10 A cross section is shown of the member 205. It will be shown that such locking can be achieved by means of a rectangular slot.

[0170] like Fig.14As shown, region 57 is a portion of the valve stem 104 of the cartridge unit 604. The region 57 has an upper portion 58 configured to be rotatably coupled to the valve stem 104. Fig.12 The control stem assembly 304 shown in FIG. 1 is shown in FIG. 1 and is assembled with the lower portion 66 , which is configured to be received within the body 90 when the valve stem 104 is located within the passage 68 of the body 90 .

[0171] like Fig.14 As shown, region 57 is a portion of the valve stem 104 of the cartridge unit 604. The region 57 has an upper portion 52 adjacent to an upper region 58, which is configured to be rotatably coupled to the valve stem 104. Fig.39 The inner surface 34 of the cam assembly 410 shown in FIG. 4 is assembled with the lower portion 66 , which is configured to be received within the body 90 when the valve stem 104 is located within the passage 68 of the body 90 .

[0172] like Fig.14 As shown, the valve stem 104 of the cartridge unit 604 has a region 59, which is configured to Fig. 9 and Fig.10 The bonnet nut 205 is shown to rotate independently and substantially frictionlessly within the member 45, and the region 59 has a lower portion 66 configured to be received within the interior of the body 90 when the valve stem 104 is located within the passage 68 of the body 90. The region 59 is adjacent to the member region 52.

[0173] The region 57 of the valve stem 104 has a portion 56 that is configured to be rotatably coupled to the valve stem 104. Fig.13 The inner surface 34 of the stopper assembly 404 is shown assembled with the lower portion 66, which is configured to be received within the interior of the body 90 when the valve stem 104 is located within the passage 68 of the body 90. The region 56 is adjacent to the region 59.

[0174] See also Fig.14 The stem 104 of the cartridge 604 has a lower portion 66 that is configured to be assembled in a rotatable relationship with the internal passage 68 of the body 90 when the valve stem 104 is located within the passage 68 of the body 90. Fig.14 As shown, the upper portion 55 of the valve stem 104 can have a groove 85 for receiving at least one sealing ring 72. Fig.14 When the valve stem 104 is integrated into the passage 68 of the body 90, the sealing ring 72 is used to prevent leakage around the valve stem in the area 55. Fig.14 As shown, the lower portion 66 of the valve stem 104 has at least one groove 87 for the sealing ring 74. Fig.14 When the valve stem 104 is integrated in the passage 68 of the body 90, the sealing ring 74 is used to prevent leakage between the inner surface of the body 90 and the lower end portion 66 of the valve stem 104. The sealing ring 74 is located in the inclusion 87 of the valve stem 104.

[0175] The upper end region 57 of the valve stem 104 may preferably have a threaded fit or other snap fit, slide-in, friction fit or gripping surface for attaching the cartridge to the faucet handle so as to be rotatable and function with the handle 20. The lower end portion 66 of the valve stem 104 has a bottom surface 96 to which the feature 98 is attached. Figure 6 The upper end portion 58 of the region 57 shown in FIG. 5 is configured to fit over Fig.12 The valve stem 104 can be formed of a one-piece structure of stainless steel, brass or zinc alloy or copper alloy or other safety metal plastic.

[0176] The bottom surface 96 of the valve stem 104 preferably has a rectangular prismatic feature 98 extending from the surface 96. The rectangular prismatic feature 98, when received within the rectangular prismatic slot 100 of the movable disk 102 within tolerance, will be shown to allow interaction with the movable disk 102 such that when the portion 58 of the region 57 of the valve stem 104 is assembled within the faucet handle assembly 304 and the lever 20 is rotated a predetermined angle, it in turn causes the movable disk 102 to rotate approximately the predetermined angle of the lever assembly 304 and thereby actuate the open / close feature of the cartridge valve. Fig.12 The configuration of a faucet handle assembly 304 is shown. Fig.15 The configuration of the removable disk is shown.

[0177] See also Fig.14 The area defined by areas 57 and 59 is free to move substantially frictionlessly within the reduced diameter area 45 of the valve cover nut 205. The valve cover nut serves to substantially ensure the stability of the cartridge unit.

[0178] See also Fig.15, showing the configuration of the movable disk 102. The movable disk 102 can have an inclusion 110, the inclusion 110 includes parabolic arc 91 and mirrored parabolic arc 94, parabolic arc 92 and mirrored parabolic arc 95, line segment 96 and mirrored line segment 97. The inclusion is further defined by line segment 95 and line segment 99. The inclusion 110 is mirrored on the opposite surface of the movable disk 102. The movable disk 102 can also preferably have a prismatic inclusion 100, wherein the inclusion 100 acts to allow the extended tab 98 of the valve stem 57 to rotate so that when the unit 57 is actuated to rotate by actuation of the control lever 20 for its utility, the movable disk 102 can be rotated against the fixed disk 112, and the disk 102 allows fluid to enter the port 110 of the movable disk 102 through the port 114 of the fixed disk 112.

[0179] Furthermore, the upper surface of the movable disk 102 is arranged in a cross section described as a cross section of a cylinder defined by two parallel chords shaped to fit within the generally cylindrical portion of the channel 68 in the lower portion 78 of the channel 68. The diameter inclusion 110 in the lower portion of the movable disk 102 serves as a fluid receiving port for the movable disk 102.

[0180] A removable disc 102 included in the body in the passage 68 has features on its upper surface 104 configured to contact and interact in rotatable relation with the bottom surface 96 of the lower end portion of the valve stem 66. As shown, the upper surface 104 is preferably configured with a slot 100 for receiving the tab 98 therein. The disc upper surface can preferably be defined as a portion of a cross-section of a solid cylinder defined by symmetrical parallel chords that are shaped to fit within the preferably generally cylindrical portion of the passage 68 in the lower portion 78 of the passage 68. Preferably, there are two side wall portions defining (preferably) two fluid receiving areas 110 within the removable disc 102. The receiving areas 100 are configured such that when the disc 102 is rotated to align the receiving areas 100 with the side openings 82 in the body 68, it will allow fluid to flow out of the side openings of the body for supplying a faucet equipped with fluid that enters the cartridge from the conduit through the open inlet 70 of the cartridge.

[0181] See also Fig.16, shown is a fixed disc 112. The disc 112 is fixed in a position for interacting with the movable disc 102. The fixed disc 112 is preferably arranged with an opening 114 extending through the fixed disc 112 for enabling a fluid flow from the inlet end 70 of the body 90 then into the passage 68, and through the fixed disc and then into the receiving area 110 of the movable disc, and then out of the side opening 82 of the body when the cartridge is in the open position mode. The fixed disc 112 can preferably be implemented with a dimple 115 containing a lubricant; the lubricant in the dimple containing the lubricant acts to reduce the friction between the movable disc 102 and the fixed disc 112, thereby further prolonging the functional integrity of the movable disc 102 and the fixed disc 112. The fixed disc is further arranged with a diameter tab 118; the tab 118 enables the disc 112 to be fixed in a recess in the internal passage 68 of the body cartridge 90.

[0182] See also Fig.17 , another view of the fixed disk 112 is shown. Fig.18 , shows the configuration of the fixing disk 112, which is positioned so that the diameter of the protrusion 118 is recessed into the body 90 of the cartridge unit 420. Fig.19 , which shows a view of the removable disk 102. Fig. 20 , shown is the relationship between the movable disk 102 and the fixed disk 112 when the cartridge valve unit 604 is in the closed mode, thereby substantially preventing liquid from flowing from the conduit 70 through the passage 68 to the side opening 82. Fig.21 , shown is the relationship between the movable disk 102 and the fixed disk 112 when the cartridge valve unit 420 is in the open mode, thereby allowing liquid to flow from the conduit 70 through the passage 68 and to the side opening 82. As will be shown, when the control lever handle 20 is assembled to Fig.14 When the portion 58 of the region 57 of the valve stem 104 shown in the figure can be rotated to reduce and cut off the flow, the disabling and enabling of the flow of liquid through the valve cylinder unit is enabled. Therefore, the handle 20 starts to close the valve from the open mode of the valve, and when the handle 20 is started to be rotated, the valve is opened from the closed mode of the valve.

[0183] See also Fig. 22 , shown is a view observed from the side opening 82 of the barrel unit 420 when the barrel unit 420 is in the closed mode. Fig.23 Shows Fig. 22 A diametric cross section of the view of , and here the diametric cross section is located in the symmetry plane of the most basic dimension of the preferably rectangular prismatic slot 100 across the movable disk 102.

[0184] See also Fig.24 , showing a 90 degree rotation of Fig. 22 View of the barrel 420. Fig.25 Shows Fig.24 A diametric cross section of a view of , wherein the diametric cross section is located in a symmetry plane on the smaller dimension of the preferably rectangular prismatic slot 100 of the movable disk 102.

[0185] For clarity, see e.g. Fig.23 The cartridge configuration shown; for the cleaning of the lever 20, when the lever handle 20 is attached to the valve stem portion 58 of the valve stem 104, the rotation of the valve stem 104 enables the opening and closing of the valves 102, 112, and thus enables the practicality of the present invention. The cleaning of the lever 20 of the present invention is enabled when the lever arm 20 is attached to the valve stem region 58 of the valve stem 104 and the lever 20 is activated to rotate through a maximum predetermined angle, which is greater than the angle of turning from the spout 10 to the flow line 777. The initial maximum predetermined rotation of the valve stem 104 by the lever 20 from the closed mode of the cartridge 420 will be shown to reduce the flow rate through the spout 10 to enable the detergent to spread on one hand and clean the hand; the subsequent reverse rotation through the predetermined angle enables the lever 20 to intercept the flow line 22 from the spout 10 and also increase the flow rate through the spout 10 to its pre-designed maximum value, thereby enabling the cleaning of the lever 20 and further cleaning of the hand. The lever 20 is then rotated in the opposite direction through a predetermined angle so that the lever arm 20 can be repositioned back to its closed position. Thus, the reduction in the solvent flow rate through the nozzle 10 enables a significant saving in the use of water as solvent, while the cleaning of the lever 20 significantly enables the transmission of pathogens to be reduced, thus enhancing health and safety.

[0186] See also Fig.16 The fixing disk 112 can have preferably diametrically paired extensions 118 for locking the fixing disk 112 within the internal passage 68 of the cartridge body 90; thus, the reliability and stability of the cartridge unit 420 can be achieved. Fig.18 The means for locking the fixed disk 112 can be achieved when an inclusion is designed within the internal passage 68 of the body 90 and the inclusion in the passage 68 of the body 90 is sized to accommodate and fit the diameter extension 118 of the fixed disk 112. The fixed disk 112 interfaces with the movable disk 102 located in the passage 68 of the cartridge body 90 and with the conduit 70, in which preferably the opening 114 in the fixed disk 112 accommodates the flow to the receiving area 110 of the movable disk 102 and then through the side opening 82 to the outside of the body 90 of the cartridge unit 420.

[0187] See also Fig.25 , the conduit 70 is outside the internal passage 68, therefore, in order to ensure the reliability of the cartridge unit, an elastomeric seal 88 is introduced to engage the fixed disk 112 and the conduit 70 in the region 132 of the cartridge body 90. The sealing ring 88 included in the component 132 acts to apply pressure between the stationary valve member 112 and the movable valve member 102. The pressure applied by the sealing ring 88 ensures the optimal function of the cartridge for liquid flow. The fixed disk 112 can also have a dimple-shaped feature 115. The lubricant in the dimple-shaped feature 115 acts to allow the movable disk 102 to move substantially frictionlessly on the surface of the fixed disk 112, thereby also extending the functional integrity of the cartridge unit 420.

[0188] See also Fig.26 , which shows that when Figure 1 The faucet system is shown in a closed mode but arranged to enable liquid to flow to the faucet when actuated, with the position of the tab 118, the orientation of the movable disk 102 and the orientation fixed disk 112, and the cross-section through the lower portion 132 of the cartridge body 90 being exploded in a sequentially assembled sequence. Fig.26 In comparison, see Fig. 27 , which shows that when Figure 1 The integrated and relatively continuous orientation of the movable disk 102 and the fixed disk 112 in the channel 68 of the lower portion 132 of the body 90 when the faucet system is in a closed mode but is arranged to enable liquid to flow to the faucet when actuated.

[0189] See also Fig.28 , which shows that when Figure 1 The faucet system shown in FIG. 1 is in an actuated mode but is arranged to allow liquid to flow generally through the spout 10 when the control lever 20 does not intercept the flow line 777 from the spout 10 to the wash basin, the position of the tab 118, the orientation of the movable disk 102, the orientation of the fixed disk 112, and the sequential assembly of the cross-section through the lower portion 132 of the cartridge body 90. Fig.28 In comparison, see Fig.29 , which shows that when Figure 1 The integrated and relatively continuous orientation of the movable disk 102 and the fixed disk 112 in the channel 68 of the lower portion 132 of the body 90 when the faucet system is in the actuated mode but arranged so that liquid can generally flow through the spout 10.

[0190] See 30, it is shown that when Figure 1The movable disc 102 and the fixed disc 112 are integrated and relatively continuously oriented in the channel 68 of the lower portion 132 of the body 90 when the faucet system is in an actuated mode but is arranged to reduce the flow of liquid through the spout 10, wherein the reduction in the liquid flow rate saves water as a solvent when the hands are soaked.

[0191] See also Fig.31 , shown is the sequence of sequential assembly and relative orientation of the handle 20, the orientation of the movable disk 102, and the orientation of the fixed disk 112 when the faucet system is in the off mode and liquid flow through the spout 10 of the faucet assembly for the right-hand side positioning unit of the present invention is disabled.

[0192] See also Fig.32 , the removable disk 102 is shown with a symmetry line 1020 of the removable disk 102; now see Fig.31 The 1020 is consistent with the characteristics of the rigid body, and the 1020 characterizes Fig.31 The initial orientation of the axis of symmetry 1020 of 102 and after the control rod 20 has performed its predetermined rotation angle Fig.32 102 of the axis of symmetry 1020; thus indicating the rotation direction and angle of rotation of the movable disk 102 from the inactive mode to the practical mode configuration, in which the control lever arm 20 is not arranged to intercept the flow line 22 from the portion 8 of the nozzle 10.

[0193] See also Fig.33 , the predetermined maximum rotation of the movable disk 102 is shown using the symmetry line 1020 of the movable disk 102; now see Fig.32 The 1020 is consistent with the characteristics of the rigid body, and the 1020 characterizes Fig.32 The initial orientation of the axis of symmetry 1020 of 102 and after the control rod 20 has performed its predetermined maximum rotation angle Fig.33 Thus, when the cartridge system 604 is in this mode, the flow rate of the solvent over water is significantly reduced to enable soaping of the hands, and thus, as mentioned, to enable economical use of water, and by extension economic, environmental and health protection, since the lever has been cleaned by the cleaned hands before the cartridge system returns to its inactive mode by the rotation of the lever 20, and thus also reduces the spread of pathogens. When the lever 20 is rotated in the opposite direction to intercept the liquid flow line 22 from the spout 10, the cleaning of the lever 20 is enabled, so that the lever 20 is prohibited from leaving the solvent flow line from the spout 10 when the hands are being cleaned.

[0198] See also Fig.45, the cam component member 410 shows a cam area 460 having an inner groove attachment area 34 of a valve stem attachment area 462 of the cam component unit 410. In the fully assembled unit of the present invention, the inner groove attachment 34 is locked to the area 52 of the upper valve stem portion 57 of the valve stem unit 104, so that rotation of the valve stem 104 rotates the cam component unit 410 approximately at the same time. The cam unit component 410 is preferably made of a non-corrosive metal (such as copper, brass or hard plastic, etc.) to ensure maximum and extended functional reliability; the portion 462 of the cam unit component 410 is shaped like an open cylinder, so that the inner area 34 of the cam unit component area 462 is arranged to be modified to be able to match the area 52 of the upper portion 57 of the valve stem 104. See Fig.45 , the area 460 of the cam unit component 410 is arranged to have an arcuate outer cross-section 438, which is adjacent to the larger inclined side 439 and the smaller inclined side 436 of the truncated cavity cover. The open annular area 462 is grooved on its interior for mating attachment to the area 52 of the upper area 57 of the valve stem 104 of the barrel unit 420. Alternatively, the control rod 20 and the cam unit 410 are arranged as a component unit 4500, which has an open but common inner groove opening cylindrical area, and wherein the cam area 462 and the control rod handle 20 are angularly positioned on the open but common cylindrical area 462, as shown in FIG. Fig.45a as shown in .

[0199] See also Fig.45 , the cam component 460 can be implemented using a channel guide 437 that acts as a guide for a small roller bearing 495 attached to the cam follower component 496.

[0200] See also Fig.46, shown is the integration of the cam attachment component unit 410 with the upper undivided portion 57 of the valve stem unit 104 of the barrel unit 420. The cam component unit 410, the control rod 20 and the upper portion 57 constitute a rigid body, so that rotation of the valve stem 104 results in rotational movement of the cam 460 and the valve stem 104 as a unit. Therefore, the cam component unit 410 and the control rod 20 and the upper portion 57 will move as a rigid body, so that consistent with the characteristics of a rigid body, the cam 460 will rotate in accordance with the direction of clockwise or counterclockwise rotation of the control rod 20. In addition, the rotation of the cam 460 occurs in a generally relatively invariant manner in the angular configuration relative to the control rod 20, so that when the cam 460 and the control rod 20 are attached to the valve stem 104, it is possible to achieve a substantial invariance in the predetermined angular separation of the cam component 460 and the control rod 20. The cam 460 is thus generally constrained to move in a horizontal plane. The cam 460 and the control rod 20 are arranged to be assembled to the upper valve stem part 57 at intervals by groove assembly, so that the cam unit 410 can be easily manipulated to adjust or replace; in addition, the relationship between the cam and the follower can be achieved within the circular area produced by the lifting of the cam 460, thereby making it possible to conveniently position the detergent actuation unit for actuation by the cam and the follower; the detergent actuation unit will also be associated with the washing basin. Fig.46 It serves to illustrate the positioning of the cam unit 410 relative to the control rod assembly 304 ; in the assembly of the present invention, the positioning of the valve cover nut 205 will precede the positioning of the cam unit 410 , followed by the positioning of the control rod unit 305 .

[0201] See also Fig.47 , shown is the integration of the cam unit component 410 and the control rod 20 with the upper part 57 of the valve stem unit 104; therefore, as described, the integration of the cam unit 410 and the control rod 20 with the upper part 57 essentially constitutes a rigid body, so the start of the rotation of the control rod 20 starts the rotation of the valve stem 104 and thus starts the rotation of the cam unit 410. Fig.47 It also serves to illustrate the positioning of the cam unit 410 relative to the control rod assembly 304 ; in the assembly of the present invention, the positioning of the bonnet nut 205 will precede the positioning of the cam unit 410 , followed by the positioning of the control rod unit 305 .

The detergent accommodating unit is equipped with a preferably cylindrical detergent reservoir 716, which has a device 726 for enabling the flow of detergent from the detergent reservoir 716 or disabling the flow of detergent. The component 712 of the detergent reservoir is used as a spiral groove cover. The removal of the spiral groove cover 712 enables the detergent accommodating reservoir to be refilled. The detergent accommodating reservoir can also have an opening 714. The opening 714 is used to enable the detergent fluid to enter regions 487, 464 when the movement of the piston 491 enables the pressure difference between the region 487 and the detergent accommodating reservoir 716 to be realized. When the pressure in the region 487 is allowed to be less than the pressure of atmospheric pressure, the opening 714 makes the pressure in the accommodating reservoir 716 atmospheric pressure, thereby enabling liquid detergent to flow in the region 487. The detergent reservoir 450 is preferably made of polypropylene, polystyrene, polycarbonate plastic or alliance-compatible transparent or see-through recyclable plastic. The transparent or see-through reservoir 450 enables better management of detergent solution so that the detergent reservoir 450 can be refilled or replaced in a timely manner. Due to the expected multiple interventions of the reservoir 450, recyclable materials for refilling or replacing the reservoir 450 are preferred, thereby achieving environmental energy and material savings.

[0226] See also Fig.74 , the detergent holding unit can utilize a preferably cylindrical duct 722, which preferably has a radius smaller than 716 but is adjacent to the detergent holding reservoir 716. The duct is equipped with a thicker wall cylindrical annulus area 720, wherein the radius of the central concentric opening 718 is smaller than the radius of the cylindrical arrangement part 722.

Fig.79 , shown is the orientation of the component 726 in area 732 when the component 726 enables detergent to flow from the detergent holding reservoir 716; the conduit 718 is then aligned generally parallel to the conduit 728, thereby enabling the flow of detergent fluid from the holding reservoir 716.

[0231] See also Fig.80 , the clockwise rotation direction of the control rod 20 for the present invention will now be formulated. The counterclockwise rotation direction of the control rod 20 is a mirror action of the clockwise rotation direction. The description of the function of the entity is for the following embodiment: detergent is discharged approximately at about the same time that water can flow through the spout 10 for hand washing, thereby coordinating between: the translation of the piston approximately parallel to the axis of the cylindrical arrangement 464; the compression length of the spring 483; the lifting of the cam 410; the stroke of the valve 482 before the detergent is discharged; the retraction of the cam 410 before the maximum predetermined rotation angle of the control rod 20 is completed is enabled and coordinated within the maximum predetermined rotation angle of the control rod 20. For timely dispensing of detergent, an embodiment of the present invention is preferred, wherein the leading edge 486 of the piston member 491 is approximately close to the outlet valve 482 in the inactive state. Preferably, the cleaning of the control rod is enabled at the reverse rotation of the control rod 20 and after the maximum predetermined rotation of the control rod 20 is completed.

[0232] When the cam 460 retreats to its maximum predetermined rotation angle when the lever 20 is rotated from the closed position to its closed position, the cleaning of the lever 20 is preferably enabled upon the reverse rotation of the lever 20 and after the completion of the maximum predetermined rotation angle of the lever 20. When the stops 60, 61 limit the lever 20 to its predetermined maximum rotation angle, the vertical flow line of water from the spout 10 is not intercepted by the lever 20. Therefore, the utility of the present invention arranges its use to wash hands only with detergent before the maximum predetermined rotation of the lever 20 when water flows through the spout 10, followed by the option of cleaning the lever after the completion of the maximum predetermined rotation of the lever 20. Therefore, when the movable disc 102 and the fixed disc 112 are configured for rotation of 90 degrees with a maximum opening 114 in the fixed disc, the predetermined maximum rotation angle of the lever 20 is greater than 90 degrees, so the stops 60, 61 on the body surface 90 are not arranged to be only diametrically opposed.

[0233] See also Fig.80 , shown is through Fig.39 A vertical plane cross-sectional view of the overall configuration of the cam component unit 410 shown in FIG.

[0234] See also Fig.81 , shown is a cross section in a horizontal plane of the detergent actuation unit 430; the cam follower 496 is configured to act as an offset follower 496, which can be activated using a roller bearing 495. The cylindrical axis of the cam follower 496 coincides with the line 810 of the cylindrically arranged cam follower 496.

[0235] See also Fig.80 , the part 486 of the piston part 491 is constrained to be substantially adjacent to the valve part 482, so that the spring part 483 is present in its relaxed configuration, thereby enabling the outlet 478 to be closed by the valve part 482. Fig.80 , when the valve 632 is deactivated, the member 631 rests on the shoulder 629, thereby enabling the detergent to flow through the conduit 628 to the areas 487 to 464 when the system is activated to begin functioning, wherein this activation action constitutes a back and forth movement of the piston 491 to open and close the valve member 632. The back and forth movement of the piston member 491 activates the opening and closing of the valve 632, thereby enabling Fig.74 The pressure difference between the internal volume 716 of the detergent reservoir 450 and the area 487 of the cylinder 498 for the detergent actuation unit 430 is depicted in FIG.

[0236] See also Fig.81 , which shows that when Fig.81 When the configuration depicted in the figure exists as an inactive configuration, Fig.39 The cam component unit 410 shown in Fig.40 The barrel component 420 shown in Fig.41 The detergent actuation unit shown in Fig.42 The inlet valve component unit shown in Fig.43 A cross-sectional view in a horizontal plane of the integrated configuration of the detergent containing unit is shown in FIG.

[0237] See also Fig.82 , which is a graphical representation of the inactive state of the present invention. In the inactive state, when the control lever handle is parallel to the member 496, the valve 632 is normally open and the valve 482 is normally closed. The leading edge 486 of the piston member 491 is generally close to the valve 482, and in addition, the outlet spring 483 and the inlet spring 621 are in a relaxed state. Fig.82 Leading edge 486 and valve 632 are shown between lines 1021, 1022. Outlet 478 is between lines 1022 and 1023. Outlet 478 is sized in diameter to be smaller than the spacing between lines 1022 and 1023, so by selecting the travel of the leading edge to be greater than the spacing between lines 1021 and 1022 before valve 478 opens, both valves 632, 482 can be closed to allow pressure to build in 487 before valve 482 opens, thereby dispersing fluid through conduit 478 while valve 632 remains closed.

[0238] Preferably, detergent is discharged substantially simultaneously with or immediately before water begins to flow through the spout 10. Prior discharge of detergent is permitted when the movable disk 102 sufficiently blocks the area 114 of the fixed disk 112 to allow the valve stem 104 to rotate, so that the cam 460 and the follower 496 interact to actuate the discharge of detergent before water flows through the opening 114 of the fixed disk. The geometric relationship between the angular position of the cam 410 on the valve stem 104, the lift of the cam 410, the follower 495, the leading edge 464 and the valve 482 can allow for timely discharge of detergent within the rotation interval of the control rod 20.

[0239] See also Fig.83, it is shown that when the control rod 20 has been further rotated clockwise by a predetermined angle (for example, clockwise) and the cam unit 410 is at its maximum displacement and the spring 483 applies a maximum restoring force to the outlet valve unit 482, Fig.39 The cam unit 410 shown in Fig.40 The barrel component 420 shown in Fig.41 The detergent actuation unit shown in Fig.42 The inlet valve component unit shown in Fig.43 4. A vertical cross-sectional view of the integrated configuration of the detergent holding unit shown in FIG. 4. When the control lever 20 is further rotated clockwise, the cam 460 intercepts the cam follower 496. The piston 491 is generally constrained by the channel 492 to move only by translation, thereby enabling the predictable function of the present invention.

[0240] See also Fig.83 The rotation of the control rod 20 enables the bevel 488 of the piston 491 to act as a wedge to intercept and initiate the vertical translation of the valve member 632, thereby Fig.67 The inlet valve assembly 682 is shown to be moved away from its seat 629 and thus to initiate the deformation of the spring 621 and thus to enable the restoring force on the spring 621 and thus to enable the member 632 to be Fig.60 The normal force is transmitted to the piston unit component 491 shown.

[0241] therefore, Fig.60 The piston unit component 491 shown is subjected to the axial force of the outlet spring component 483 and the normal force of the inlet spring component 621, wherein the inlet spring force of component 621 acts on the piston unit component 491 to resist the influence of the outlet spring force on the piston unit component 491, and thus enables the spring component 621 to be selected, and when there is interaction between the cam 410 and the piston 491, the spring component 621 will offset the influence of the spring 483 on the rotation of the valve stem 104.

[0242] In addition, the vertical movement of the valve member 632 further enables the valve 632 to close, thereby prohibiting the liquid detergent from flowing through the pipe 628 to the area 487 of the cylinder 498, so that fluid pressure can be established in the area 487 of the cylinder 498 when the control rod 20 continues to rotate, and when the valve 482 is still closed, the valve member 632 continues to maintain stress on the piston member 491.

[0243] See also Fig.83The control rod 20, the cam 460 and the valve stem 104 are roughly used as a rigid body, so that the clockwise movement of the control rod 20 enables the cam unit 410 to translate the piston 491, thereby enabling the piston extension 486 to intercept and translate and open the outlet valve 482, and thereby enabling the detergent fluid to be ejected through the outlet 478.

[0244] See also Fig.83 , the cam 460 translates the piston extension over its ascending interval by a measure which is roughly the measure of the lift achieved by the cam 460, so that the extreme point on the radius of the cam 460 is located at Fig.84 The outlet spring member 483 will thus have distorted the displacement of the lift effected by the cam 460 substantially as much as the distortion displacement of the spring member 483 is permitted by the physical properties of the spring member 483. The cam member 460 is predetermined to achieve its maximum lift before achieving a maximum predetermined clockwise rotation angle of the control rod 20.

[0245] See also Fig.85 , shown is the closure of valve 632 and the opening of valve 482 between lines 1022 and 1023. Cam 460 is now at its maximum lift and spring 482 is now exerting a maximum restoring force while spring 621 exerts a force on piston member 491. Control rod 20 has not yet rotated past its maximum predetermined angle. The geometry of fixed disk 112, movable disk 102, and the configuration of control rod 20 relative to fixed stops 60 and 61 are Fig.25 As shown in FIG. 1 , the fixed stops 60 , 61 are positioned on the upper surface 130 .

[0246] Upon initial rotation of the lever 20 , when detergent has been activated and water flows through the spout 10 , hands can be washed, and the tap is reversed to its off mode without activating the lever 20 for washing.

[0247] See also Fig.86 , depicted is a configuration in which the control rod 20 has performed its maximum predetermined clockwise rotation angle and the control rod 20 is prevented from further rotation by the restrictive cartridge body stop 61. The cam 460 is now locked by the follower 496 in a biased configuration by the axial force of the spring 483, the biased configuration having further rotation limited by the body stop 61, and the force of the spring 621 acting on the piston 449, thus enabling the flow of solvent (such as water, etc.) without interruption when using the present invention, such as hand washing. The configuration of the fixed disk 112 and the movable disk 102 can now be made to reduce the flow rate through the nozzle for the predetermined maximum rotation angle of the control rod 20.

[0248] See also Fig.87 , depicted is Fig.86 A top view of the configuration shown in FIG.

[0249] See also Figure 87a , shown is a diagrammatic representation in an active state when the control rod 20 has been rotated through its maximum predetermined rotation angle and the piston 49 is about to withdraw from the valve 482 while being acted upon by the axial force reduced by the spring 483.

[0250] See also Figure 87a , cam 460 has now also been retracted and the size of the cross section of outlet duct 478 and the spacing between lines 1022 and 1023 have been selected to close valves 482 and 632. The combined force of spring 621 on piston 491 and the reduction of the force of spring 482 coupled to the bias combined with the action of stop member 61 immobilizes the lever at its maximum predetermined rotation angle, so that water or any other solvent can flow through spout 10 without interrupting the washing of the hands.

[0251] See also Fig.87 b, shown is Figure 87a Compared to the cross-section including the outlet 478. When the cam 460 is retracted when the control lever 20 is rotated to its maximum predetermined rotation angle, preferably when the cam 460 is blocked in the biased configuration, the outlet 478 is enabled between the areas 1023 and 1024, thereby enabling the valve 632 and the valve 482 to be in a closed mode, thus minimizing dripping or leakage.

[0252] Reverse rotation of the lever 20 enables said lever to intercept the flow line 777 from the spout 10 enabling cleaning of the lever 20 and further cleaning of the hands.

[0253] When Fig.86 When the system depicted in FIG. 1 is deactivated after use, the control rod 20 is further rotated counterclockwise, thereby enabling the valve 482 to be closed when the valve member 632 is open, so that further counterclockwise rotation of the control rod 20 enables a pressure difference in the area 487, and thus enables detergent flow in the area 487 when the valve member 482 can be closed before opening the valve 632. The system is now in a state for its next practical function.

[0254] The interaction between the cam 460 and the cam follower 496 is independent of the fixed position of the cam 460 on the upper portion 57 of the valve stem unit 104, thus enabling flexible selection of the detergent actuation system to be positioned using a faucet system. In addition, multiple configurations enable timely dispensing of fluid when the control lever 20 is rotated.

[0255] See also Fig.88 , shown is a vertical section in a plane symmetrical to the detergent actuation unit and the detergent reservoir relative to the positions of the cam unit 410, the drum unit and the control lever unit in an inactive or closed mode of the present invention.

The outer surface of the cartridge mount 920 between the upper reduced diameter area 919 and the lower larger diameter area 926 is spirally grooved for rigidly attaching the cartridge mount 920 to a mounting surface via a nut. This mounting surface 981 is in Fig.95 In the assembly of the present invention, when the flange 128 of the cartridge body 130 is recessed into the groove 921 of the cartridge mount 920 , the cartridge unit 420 is stabilized in the region 901 of the cartridge mount 920 .

[0283] In summary, a washable faucet lever with a cam-actuated detergent dispenser is described herein, the washable faucet lever comprising a lever barrel 420 having a valve stem 104 operably coupled to a hand lever 20, the hand lever 20 being configured to rotate on a lever rotation axis and operably coupled to a cam member 410 having an arcuate outer surface, and configured to rotate on a cam rotation axis parallel to and synchronized with the lever rotation axis. In one embodiment, the cam member 410 has a larger inclined side surface 439 and a smaller inclined side surface 436 forming an arcuate outer surface. Further, the cam member 410 may also be in the shape of a cavity cover. In some embodiments, the arcuate outer surface of the cam member 410 defines a channel guide 437 for a follower 496, which includes a roller bearing 495 configured to translate (e.g., roll or slide) within the channel guide 437 to move the piston 491. In one embodiment, the cam member 410 is constrained to rotate within a single horizontal plane, as described above.

[0284] The washable faucet lever with cam-actuated detergent dispenser also includes a detergent reservoir member 450 configured to contain liquid detergent therein, the detergent reservoir member having an interior passage 718 configured to receive the liquid detergent, and having a reservoir valve 632 coupled to the detergent reservoir member 450 and operably configured to selectively translate to open and allow liquid detergent to flow through the interior passage 718 and to close and restrict liquid detergent from flowing through the interior passage 718. The dispenser also includes an enclosure member 498 defining an enclosed area 468 therein, defining an outlet 478, having an outlet valve 482 disposed within the enclosed area 468, and operably configured to selectively translate to open and allow liquid detergent to flow through the outlet 478, to close and restrict liquid detergent from flowing through the outlet 478, and biased by a spring 483 retained by the enclosure member 498. Further, the dispenser includes a piston 491, which is arranged in the closed area 468, and has a follower 496, which is movably connected to the arcuate outer surface of the cam member 410 (as discussed herein), and the follower 496 is operably configured to translate in the closed area 468 when the hand control lever 20 is rotated along the control lever rotation axis to selectively and simultaneously shift the reservoir valve 632 and the outlet valve 482 to allow liquid detergent to flow through the internal channel 718, enter the closed area 468 and flow out through the outlet 478.

[0285] In one embodiment, the piston 491 is configured to translate in a single and linear translation axis within the enclosed area 468 when the hand control lever 20 is rotated on the control lever rotation axis to selectively and simultaneously displace the reservoir valve 632 and the outlet valve 482. In other embodiments, the piston 491 is configured to translate within the enclosed area 468 when the hand control lever 20 is rotated along the control lever rotation axis and when one of the counterclockwise or clockwise rotations is rotated to selectively and simultaneously displace the reservoir valve 632 and the outlet valve 482. In still other embodiments, the cam rotation axis is coaxial with respect to the control lever rotation axis for the benefits discussed herein.

[0286] In some embodiments, mounting base 981 defines an opening in which control rod barrel 420 is disposed and coupled to the opening by at least one fastener, mounting base 981 is coupled to enclosure member 498 by at least one fastener, and mounting base 981 defines an opening in which a faucet member is disposed, mounting base 981 defines a spout 10 having an opening configured to cause liquid to be emitted therethrough, and mounting base 981 is coupled to the spout by at least one fastener. The dispenser also includes a protective cover 940 that defines an opening in which control rod barrel 420 is disposed, covers enclosure member 498, defines an opening in which a faucet member is disposed, and defines an opening in which a detergent reservoir member 450 is disposed.

[0287] In one embodiment, the dispenser includes a protective cover 940 defining an internal passage that is fluidly coupled to the outlet 478 and configured to allow liquid detergent to flow therethrough, and the reservoir valve 632 is coupled to the detergent reservoir member 450 with a spring bias. Additionally, the internal passage 718 is spatially configured in the detergent reservoir member 450 to enable liquid detergent to be received therein based on gravity.

[0288] See also Fig.100 , which shows Fig.99b Configuration, Fig.99b The configuration is assembled with the spout unit 10, the lifting stem 18, and the bonnet nut 205, wherein the bonnet nut 205 is securely associated with the cartridge housing 920. Optimal stability of the valve stem 104 is facilitated when the bonnet nut 205 is securely associated with the cartridge housing 920 and the region 45 of the bonnet nut 205 surrounds the region 59 of the control stem assembly 104. By applying a Teflon coating to the surface 59 of the valve stem unit 104, the outer surface of the region 59 of the valve stem unit 104 is able to rotate substantially frictionally against the inner surface 45 of the bonnet nut.

[0289] See also Fig.101 , which shows Fig.100 The configuration of being assembled with the detergent reservoir unit 450 in the area 487. The entry opening 487 is spirally grooved to be compatible with the outer spiral grooved portion 724 of the reservoir unit 450, so that when the outer spiral grooved portion 724 is spirally entered into the entry opening 487, the detergent reservoir is securely attached to the detergent actuation unit.

[0290] See also Fig.102, shown is an exploded conceptual view of an embodiment of the present invention having a bottom cover plate 930. The diameter of the opening 947" of the bottom cover plate 930 is superior to the most significant diameter of the nut 933, thereby minimizing the interaction effect with the drum unit when the detergent actuation unit is actuated.

[0291] In addition, when the nut 944 is attached to Fig.102 When the area 955 of the spout 10 is shown, the bottom cover plate 930 is securely interfaced with the assembly 981; in this way, the nut 944 is used to secure 930 to the lower surface 981. When the screw 948 is introduced from the upper surface of 498 through the opening 497 of 498 and then through the opening 935 of 981 and then through the opening 935" of 930, the bottom cover plate is further stabilized, so that screw fasteners can be selected and applied to securely combine the body 465 of the detergent actuation unit 430, the assembly block 981 and the bottom cover plate 930 together through one or more nut fasteners 942.
