Description

This application is a continuation in part of, and claims priority to, co-pending United States utility patent 16/740,146, filed January 10, 2020, by the same inventor, Peter Bai, entitled "Countermount Foam Dispenser," the disclosure of which is incorporated herein by reference.

This application is a continuation in part of, and claims priority to, co-pending United States utility patent 16/559,234, also filed on September 3, 2019, by the same inventor, Peter Bai, and also entitled "Countermount Foam Dispenser," the disclosure of which is incorporated herein by reference.

The present invention relates to the field of counter mounted foam soap dispensers.

A wide variety of prior art references show countertop soap dispensers. For example, in U.S. Patent No. 9,795,255, published Oct. 24, 2017, "Electronic Soap Dispenser" by inventor Michael Scott Rosko discloses in its abstract that "the electronic soap dispenser includes an upper dispense head supported above the sink deck, and a liquid soap reservoir and pump assembly supported below the sink deck. A capacitance sensor is operably coupled to the dispense head. A controller is in electrical communication with the capacitance sensor to activate the pump assembly in response to input from the capacitance sensor."

For example, U.S. Patent No. 6,929,150, published Aug. 16, 2005, by inventor Kenneth J. Muderlak, entitled "System and Method For Dispensing Soap," discloses in its abstract that "a method for dispensing soap from a fluid dispensing system is disclosed. The method includes the steps of providing a tube having a tube end disposed in a first portion within a recessed portion of a jet of the fluid dispensing system, sensing an object below the tube end in response to sensing the object, releasing soap from the tube end by drawing the tube end further into a second portion within the recessed portion, and returning the tube end to the first position."

For example, in U.S. Patent Application Publication No. 2009/0152293, published June 18, 2009, inventor Richard C. In its abstract, Sayers' "Counter-Mounted Solution Dispenser With Counter-Protective Platform" discloses that "the dispensing station is counter-mounted and includes a container. The container is maintained below the counter to hold a volume of rinse-free hand treatment product. The protective platform is positioned on the top surface of the counter, and the faucet structure has an outlet positioned above the protective platform. The pump communicates with the volume of rinse-free hand treatment product in the container, and a dispensing conduit extends through the faucet structure and communicates between the pump and the outlet of the faucet structure, whereby actuation of the pump dispenses the rinse-free hand treatment product at the outlet toward the protective platform. This dispensing station promotes use of rinse-free hand treatment products by providing a clearly defined station similar to that defined by a typical sink."

For example, in U.S. Patent No. 8,544,698, published October 1, 2013, inventor Nick E. Ciavarella, in his "Foam Dispenser With Stationary Dispensing Tube," discloses in its abstract that "a dispenser is provided including a pump for dispensing a foam product at an outlet on the dispensing tube. Foam is created from a mixture of foamable liquid and air using separate pumps on each component. The pump itself has parts that must move to dispense the foam product, while the dispensing tube is stationary. A single actuator operates both the liquid pump and the air pump. Additionally, in some embodiments, the air pump raises air before the liquid pump raises liquid. These pumps are particularly suitable for dispensing foam skin care or skin disinfecting products."

For example, U.S. Patent No. 7,364,053, published April 29, 2008, by inventor Heiner Ophardt, discloses in its abstract, "A soap dispenser, preferably a counter-mounted dispenser on the sink side, that dispenses foam liquid soap by mixing soap and air at the soap-jet liquid outlet, preferably provided from a liquid soap pump and an air pump located away from the faucet."

For example, in U.S. Patent No. 7,025,227 published on April 11, 2006, inventor Steven R. In its abstract, "Electronic Soap Dispenser" by Oliver discloses that "the liquid soap dispenser includes a housing, a shank engaging the base of the housing, a soap path retainer disposed inside the housing, a shank adapter disposed on the shank, and an infrared sensor for sensing the presence of a user. An overall continuous passageway is defined through the shank adapter and the soap path retainer, whereby an elongated soap delivery tube of a liquid soap reservoir may be inserted through the passageway from the bottom to the jet end of the soap dispenser. The reservoir may be attached to the lower end of the shank adapter. The soap path retainer is preferably formed of two complementary halves, such as plastic injection moldings, that fit together to provide a curved passageway from near the base of the housing to the soap dispensing end and to support the sensor assembly."

For example, in the specification of U.S. Patent No. 8,100,299 published on January 24, 2012, inventor Stephen Lawrence Phelps' "Counter-Mounted Viscous Liquid Dispenser and Mounting System" discloses in its abstract that "The present invention provides an in-counter viscous liquid dispensing system. Features of the viscous liquid dispensing system include a quick-attach reservoir assembly that allows an installer to install the reservoir assembly in any orientation relative to the countertop mounting components of the system. Other features include a mounting system that allows an installer to install the in-counter dispensing system without having to work both above and below the countertop."

For example, in the specification of U.S. Patent No. 8,371,474 published on February 12, 2013, "Fluid Dispenser" by inventor Paul Francis Tramontina discloses in its abstract that "the present invention is a method of dispensing fluid, and a dispenser that dispenses an appropriate amount of fluid to effectively cleanse a user's hands, even if the dispenser has not been used for a period of time."

For example, U.S. Patent Application Publication No. 2014/0263421, published on September 18, 2014, discloses "Counter Mount Above-Counter Fill Dispensing System and Refill Units for In its abstract, "Same" discloses that "Exemplary embodiments of a dispensing system and a refill unit therefor are provided. One exemplary refill unit for a counter-mounted dispenser includes a collapsible bag and a tube extending down into the collapsible bag. A fitment is secured to the collapsible bag. The fitment has a fill hole. A pump is also provided for pumping fluid from the bag. The collapsible bag fits into a countertop through an opening such that the collapsible bag can be inserted through the opening from above the countertop. At least a portion of the collapsible bag extends below the countertop. The collapsible bag is configured to be filled with liquid after being inserted into the countertop through the opening. When the collapsible bag is filled with liquid, the volume of the collapsible bag expands."

For example, in U.S. Patent No. 8,770,440 published on July 8, 2014, inventor Moses-B. Lin's "Countertop Automatic Foam Soap Dispenser" discloses in its abstract that "the countertop automatic foam soap dispenser includes an automatic foam soap dispenser body, a soap liquid container, a circulation connection tube, and a battery compartment. The soap liquid container is filled with an appropriate amount of liquid soap. The battery compartment supplies power to the automatic foam soap dispenser body. The automatic foam soap dispenser body is passed through the circulation connection tube by the soap delivery tube and is installed at the bottom inside the soap liquid container. The automatic foam soap dispenser body includes a foam soap valve, a control circuit board, a sensor, a motor controlled by the control circuit board, and a transmission set. When the user's hand approaches the sensor of the automatic foam soap dispenser body, the motor drives and rotates the cam of the transmission set, which pushes in the foam soap valve to dispense the appropriate amount of foam soap."

The tray door key 50 has a safety engagement with the tray door latch cam 48, such as by a pair of non-standard pointed instruments. The mixer pump housing 41 also includes a mix housing connector opening 58 that is shaped to receive a safety screw. The mixer housing connector opening 58 allows the connector to hold together a pair of sections of the mixer pump housing 41, such as the mixer pump housing top 49 and the mixer pump housing lower portion.

The bottle 30 is connected to the underside of the mixer pump housing 41. The bottle 30 has a sidewall 31 with a sidewall indentation gripping portion 32 that improves structural rigidity. The bottle 30 has a lower recess 33 and an upper recess 34 that also improve structural rigidity. The bottle 30 includes a bottle tube 276 that extends downward from the top of the bottle.

As seen in FIG. 2, the jet 20 has a pill-shaped, elongated, forward-facing jet sensor 21. The jet sensor 21 has a lens that provides a continuous, flush outer surface with the jet 20. The jet nozzle 22 is a frusto-conical protrusion that extends downwardly from the jet 20. The jet extension 24 is generally centered relative to the jet mounting shaft 26 and the jet shoulder 25. The mounting shaft nut 27 can be made of metal or plastic and is configured to rotate and tighten into a mounting opening formed in a countertop. The front sensor 29 is mounted to the inside of the jet 20. The front sensor 29 also has a flush lens that allows the front sensor 29 to detect the presence of a user. The front sensor 29 works in conjunction with the jet sensor 21 such that the jet is activated only when both sensors detect presence. The jet sensor 21 senses the presence of the user's hand and the front sensor 29 senses the user's torso. The indicator 56 can be mounted in the same opening as the forward sensor 29.

The tray door key handle 46 is preferably circular. The tray door key 50 may have a first key protrusion 51 and a second key protrusion 52. An opening 55 in the key handle may allow for connection to a string or other line. The pair of key protrusions, i.e., the first key protrusion 51 and the second key protrusion 52, are required to be able to rotate the tray door latch cam 48.

As seen in FIG. 3, the jet 20 can have a curved profile that extends at an angle from the jet shoulder 25. The mounting shaft nut 27 is preferably hexagonal. The bottle 30 is attached to the mixer pump in one motion.

As seen in FIG. 4, the tray door lock 50 provides access to the battery tray and is adjacent to the mixer housing connector 57. The mixer housing connector 57 preferably includes a mixer housing connector opening 58 and may have a mixer housing connector tab 59. The mixer housing connector tab 59 may be formed as a latch with a snap connection between different parts of the mixer housing.

As seen in FIG. 5, the jet 20 extends forward and the jet shoulder 25 can form a seal with the countertop. The forward sensor 29 is perpendicular to the jet extension. The mixer pump housing top 49 is preferably rectangular. The tray door lock 50 can extend laterally from the left side of the mixer pump housing. An indicator 56 is also disposed forward to provide an indication to the user.

As seen in FIG. 6, the jet 20 may have a lower portion 60 with an annular ridge on which an elastomeric ring seal may be placed. The mixer housing connector tab 59 may release the jet's retainer latch 78 at the pump outlet opening 42 to release the lower portion 60 of the jet 20. The jet's retainer latch 78 may retain the lower portion 60 at the retainer notch 79. The jet's retainer latch 78 preferably allows for a snap connection of the jet 20 to the pump outlet opening 42. In this way, the user first attaches the jet 20 using a nut in a first step, then snaps the jet's retainer latch 78 into the retainer notch 79 in a second step and engages the pump outlet opening 42 with the jet 20 in a pair of separate steps.

The user can attach the bottle 30 after attaching the pump outlet opening 42 to the lower portion 60. The user grips the sidewall 31 of the bottle 30 by the various sidewall indented gripping portions 32. The user may also use the lower recess 33 or the upper recess 34. The bottle 30 has a bottle adapter 35 attached above the bottle shoulder 39. The bottle adapter 35 snaps onto the bottle neck and creates a watertight permanent seal to the bottle. The bottle adapter 35 preferably has four adapter projections 36 that are oriented at 90° from each other and extend away from the vertical sidewall of the bottle adapter 35. The bottle adapter 35 has an adapter port 37 with an adapter port opening 38. The adapter port opening 38 connects to a bottle tube 276. The bottle tube 276 extends downward from the top of the bottle 30 at the top of the bottle adapter port opening 38.

The mixer pump 40 mixes water and air inside the mixer pump housing 41. The resulting foam soap is expelled through the pump outlet opening 42 and the jet 20. The tray door latch cam 48 has a pair of recesses that receive a pair of protrusions on the tray door key 50. The tray door key 50 has a first key protrusion 51 and a second key protrusion 52. The tray door latch cam 48 has a first latch indent 53 and a second latch indent 54 that receive a pair of protrusions on the tray door key 50. When both protrusions are in both recesses, the latch can be turned to unlock the battery tray door. The battery tray door and the battery compartment are preferably watertight.

As can be seen in FIG. 7, the various internal components reside within the various housings. The jet sensor 21 is mounted between the jet extension front housing 61 and the jet extension rear housing 62. A sensor bracket 63 can be attached to a mounting post on the jet extension front housing 61 to hold the jet sensor 21 to the jet extension front housing 61. Similarly, a foam screen 66 can remix coarse foam into finer foam and can be mounted in the cavity between the jet extension front housing 1 and the jet extension rear housing 62. A jet shoulder 25 can hold the lower semicircular edge of the jet extension housing pair. The jet mounting shaft 26 has a mounting shaft bracket 77 that attaches to the jet extension front housing 61. A shoulder gasket 64 can seal the jet shoulder 25.

The bottle 30 holds soap in liquid form and receives the bottle adapter 35. The liquid soap travels upward from the bottle tube 276. The bottle adapter 35 fits into the adapter gasket 72. The adapter gasket 72 is secured to the frame 65 of the bottle adapter receiver, which is formed as the lower portion of the mixer pump housing 41. The bottle adapter receiver may also form the lower portion of the battery tray slot and define a portion of the tray opening 75. The battery tray 44 receives the battery 73 in the battery slot 74 and is secured to the tray door lock 50 by the tray door latch cam 48. The battery system provides power to the circuit board 76.

The battery powers the motor 67, which is attached to the motor mount 68. Various flow control accessories 70 allow for quick, one-handed connection while preventing leakage. A waterproof gasket 69 made of an elastomeric material seals the liquid inlet nozzle 71, which is attached to the frame 65 of the bottle adapter receptacle and seals the adapter gasket.

As seen in FIG. 9, the alignment system 80 includes an indentation and slots for holding the bottle 30 on the bottle neck 90. The bottle adapter receiver 81 is a hollow, indented portion of the bottle adapter receiver frame 65 that is shaped to receive the bottle adapter 35. The adapter projection 36 engages the bottle adapter receiver sidewall 82. The adapter projection 36 has a cylindrical profile and extends horizontally away from the bottle adapter. The adapter projection 36 engages the bottle adapter suction funnel 83 and rotates clockwise past the bottle adapter retention ridge 84. The bottle adapter suction funnel 83 and the bottle adapter retention ridge 84 are formed in the bottle adapter retention slot 89. The bottle adapter retention slot 89 is formed in the bottle adapter receiver sidewall 82.

The alignment system 80 also includes an alignment for the bottle. The bottle adapter 35 has an adapter sidewall 85. The bottle adapter 35 has an adapter hook 86 that protrudes downward. The adapter hook 86 engages a neck groove 87 formed in the bottle neck. A rotation stop 88 interrupts the continuity of the neck groove 87 so that the adapter hook 86 abuts the rotation stop 88 when the adapter protrusion 36 engages the retention ridge 84 of the bottle adapter. As the liquid is drawn upward from the bottle 30, intake air is entrained in the liquid flow, creating a coarse foam. As the coarse foam travels upward, it can pass through additional screens or blends to sieve into a fine foam. The liquid soap is drawn up through a bottle tube 276 attached to the adapter sidewall 85.

Preferably, the upper alignment indent 91 formed on the frame 65 of the bottle adapter receiver has an upper alignment edge 92. The upper alignment edge 92 is aligned with the lower alignment edge 94. The lower alignment edge 94 is formed on the lower alignment indent 93 disposed on the bottle 30. The pair of matching alignment edges allows the user to remove and place the bottle from the frame 65 of the bottle adapter receiver by touch only without a visible guide line. The upper alignment indent 91 holds the lower alignment indent 93 so that the inner surface of the upper alignment indent 91 abuts the outer surface of the lower alignment indent 93. The alignment indent thereby matches the bottle to the receiver 81 of the bottle adapter. The receiver 81 of the bottle adapter will only receive bottles with a suitable alignment indent. The alignment indent on the bottle is formed on the bottle shoulder. The bottle shoulder may be slightly flexible to allow the pair of matching indentations to rotate into the receiving portion 81 of the mating bottle adapter.

As seen in FIG. 10, the motor 67 is part of the pump assembly 100. The motor 67 has a motor housing 109 and a motor shaft 110 extending from the motor housing 109. The motor shaft 110 extends into the tailstock 108. The tailstock 108 is a housing that holds the crank 107 and the piston handle. The crank 107 has a motor shaft mounting opening 111. The motor shaft mounting opening 111 is offset from the piston handle shaft opening 112. The crank 107 has a piston handle shaft opening 112 that holds the piston handle shaft 113. The piston handle shaft 113 swings cyclically around the motor shaft 110 and is angular relative to the motor shaft 110. The piston handle 106 has three extended piston handle arms 114. Each of the piston handle arms has a piston handle diaphragm engagement portion 115. The piston handle diaphragm engagement portion 115 engages the piston diaphragm 104 at the piston diaphragm tip 116. The piston diaphragm tip 116 is connected to and integrally formed with the piston diaphragm cup 117. The piston diaphragm cup can be cylindrical or cone shaped and fits into the piston bracket recess of the piston bracket 105. As the piston handle shaft 113 rotates, it in turn pushes down the piston handle diaphragm engagement portion 115, which in turn pushes down the piston diaphragm tip 116, thereby in turn reducing the volume of the piston diaphragm cup 117. The piston diaphragm 104 has a flat portion that seals against the piston bracket 105, so that the piston diaphragm 104 does not rotate relative to the piston bracket 105. The piston bracket 105 also does not rotate relative to the tailstock 108, because the piston bracket 105 is fixed to the tailstock 108 by a connector such as a screw.

The filter net 103 in the mixer 122 sieves the liquid to produce a coarse foam output from the mixer 122. The mixer is separated from the pump area by some distance to prevent foam from backflowing into the motor. The output nozzle cover 101 has an air inlet port 120 and an air outlet port 121.

The generated air is used for power and air flow and enters the air flow mixer 122 where it mixes with the liquid soap to create a coarse foam through the screen. The rubber stop 102 selectively allows and controls the air to enter in a circular manner. The liquid inlet port 119 is connected to the bottle. The rubber stop 102 can act as a one-way valve, and the air inlet port 120 also preferably includes a one-way valve to prevent leakage. The air inlet port 120 can have a one-way valve installed such as by a plastic sheet, ball stop, or other type of circularly engaging seal. It is desirable that liquid does not enter the pump area and is restricted only to the mixer area. Liquid can leak around the piston diaphragm 104 and destroy the motor if liquid enters the output cover 101. Therefore, it is essential to keep the output cover 101 dry. It is preferable that the pump is connected to the mixer by a plastic tube or separated by a one-way flow valve. The foam outlet port 118 releases the generated foam created from the aspirated air through the air inlet port 120 and the liquid inlet port 119 in the mixer. It is a feature of the present invention to separate the membrane pump area from the foam mixing area to increase the life of the electric machine components.

The plastic tubing that connects to the components in the present invention is not shown in the drawings for clarity, as the appropriate connections are obvious. For example, a component such as the liquid inlet nozzle 71 preferably has a liquid inlet nozzle tube connector 95 that can be connected to the liquid inlet port 119 by tubing.

11, the jet 20 may have a jet sensor 21 formed on a sidewall of the jet 20. The jet 20 may further receive a jet shoulder 25 secured to a jet mounting shaft 26 having a threaded outer surface that receives a mounting shaft nut 27. The lower end of the jet mounting shaft 26 has a swivel socket connector 130. The swivel socket connector 130 includes connections to a first swivel hose 131 and a second swivel hose 132. The first swivel hose 131 is in fluid communication with a first swivel nipple 133. The first swivel nipple 133 connects to a tube exiting the pump. The second swivel nipple 134 is in fluid communication with the second swivel hose 132. A swivel socket circlip 135 connects to a swivel socket flange 136 at the swivel socket connector 130. The swivel socket flange 136 is preferably formed as a protrusion extending laterally from the cylindrical sidewall of the swivel socket connector 130. The lower circlip edge 138 engages the pump outlet opening flange 139, FIG. 12, formed at the pump outlet opening 42. The upper circlip edge 137 engages the swivel socket flange 136. The swivel socket circlip 135 biases the pump outlet opening flange 139 toward the swivel socket flange 136.

The mixing socket 150 is located in the jet 20. The mixing socket 150 has a pair of connections, a first mixing socket nipple 151 connected to the first swivel hose 131 and a second mixing socket nipple 152 connected to the second swivel hose 132. The mixing socket 150 has a mixing socket body 153 with a cylindrical barrel housing having a protruding anchor that engages the body of the jet 20. The mixing chamber housing 154 can be inserted into the hollow socket of the mixing socket body 153 with a cartridge. The mixing chamber housing 14 sieves and mixes the liquid and air to form a fine foam. The nozzle attachment 155 is connected to the mixing chamber housing 154, which enters the mixing socket body 153.

12, the pump outlet opening 42 has a pump outlet opening flange 139. The pump 160 pumps both liquid and air. The piston diaphragm 104 has two air diaphragms and one liquid diaphragm separated from each other by a piston diaphragm seal 161 for independent operation. The pump 160 includes a piston bracket 105. The piston bracket 105 holds the piston diaphragm 104, the piston diaphragm seal 161, and the divider pump manifold 140. The piston diaphragm cup 117 preferably includes three cups: a first diaphragm cup 191, a second diaphragm cup 192, and a third diaphragm cup 193.

13, the divider pump manifold 140 may be formed of a pair of plastic injection molded housings or shells that fit together to form an internal conduit passageway. The air conduit 141 has an air conduit proximal portion 181 and an air conduit distal portion 182. Similarly, the liquid conduit 142 has a liquid conduit proximal portion 183 and a liquid conduit distal portion 184. The air conduit proximal portion 181 is separated from the air conduit distal portion 182 by an air compartment 143. The air compartment 143 extends to a liquid compartment 148, which separates the liquid conduit proximal portion 183 from the liquid conduit distal portion 184.

The first liquid port 144 is in fluid communication with the second liquid port 147, whereby liquid may be pumped from the first liquid port 144 to the second liquid 147, or liquid may be pumped from the second liquid port to the first liquid port. The first liquid port is connected to the distal portion 184 of the liquid conduit 142, and the second liquid port 147 is connected to the proximal portion 183 of the liquid conduit. The reciprocating diaphragm pumps liquid from the distal portion 184 of the liquid conduit to the proximal portion 183 of the liquid conduit, or pumps liquid from the proximal portion 183 of the liquid conduit to the distal portion 184 of the liquid conduit. Reciprocating diaphragm

Similarly, the first air port 145 is in fluid communication with the second air port 146, so that air can be pumped from the first air port 145 to the second air port 146 or from the second air port 146 to the first air port 145. Liquid and air hoses can be connected to the ports. The distal air opening 162 of the first diaphragm leads to the distal portion 182 of the air conduit, and the proximal air opening 163 of the first diaphragm leads to the proximal portion 181 of the air conduit. The first diaphragm exchanges air between the distal opening 162 of the first diaphragm and the proximal opening 163 of the first diaphragm. The second diaphragm exchanges air between the proximal air opening 164 of the second diaphragm and the distal air opening 165 of the second diaphragm. The proximal air opening 164 of the second diaphragm connects to the proximal portion 181 of the air conduit, and the distal air opening 165 of the second diaphragm connects to the distal portion 182 of the air conduit. These openings can receive a one-way valve or seal 161 that allows air or liquid to pass in a particular direction. The seal 161 can also be integrally formed as a gasket with an elastomeric material composition. The seal 161 can be an intermittent seal that seals air or liquid from passing through a particular opening in a particular direction. The seal 161 is formed as a plastic flap on the sheet that blocks the proximal air opening 163 of the first diaphragm, and the volume reduction of the third piston in the piston diaphragm 104 will force air through the distal air opening 162 of the first diaphragm. The subsequent increase in volume of the third piston in the piston diaphragm will draw air through the proximal air opening 163 of the first diaphragm by moving the plastic flap away from the opening to allow an airflow gap. Instead of a plastic flap, an on-off valve can be implemented as a rolling bearing or other means.

The third diaphragm in the piston diaphragm seal 104 pumps liquid between the distal liquid opening 166 of the third diaphragm and the proximal liquid opening 167 of the third diaphragm. The distal liquid opening 156 of the third diaphragm is connected to the distal portion 184 of the liquid conduit and the proximal liquid opening 167 of the third diaphragm is connected to the proximal portion 183 of the liquid conduit. Optionally, an adapter 194 can accommodate the cup opening to the seal 161 when the cup opening and seal are attached.

13 as the pump housing and piston diaphragm cup, it should be noted that this is merely to show the alignment of the circular seal in the piston diaphragm cup 117 with the circular seal in the adapter 194. The adapter 194 is actually behind the piston diaphragm cup 117 when installed, so that the circular seal of the adapter 194 is aligned behind the piston diaphragm cup 117 to accommodate the piston diaphragm cup 117 with the elastomeric seal 161. The piston diaphragm cup 117 is preferably flexible and the adapter 194 is preferably rigid. The elastomeric seal 161 is preferably flexible and the manifold is preferably a rigid item. Thus, the alternating rigid and flexible items provide an improved seal in a sandwich-like manner.

As seen in FIG. 14, the bottle 30 has a bottle adapter 35 with an adapter port 37, but an adapter protrusion 36 is formed on the neck of the bottle 30. As seen in FIG. 15, the bottle 30 has a sidewall indented gripping portion 32 that allows for a grip to engage the adapter protrusion 36 formed on the neck of the bottle 30. The adapter protrusion 36 can be formed as a lug or locking protrusion that holds the bottle and bottle adapter 35 to the housing. The bottle shoulder 39 of the adapter port 37 narrows to a narrow neck.

Thus, the main point of the present invention is that the pump provides a metered output, i.e., one pulse of liquid, then two pulses of air in a rapid cycling sequence. The rotating arrangement of the diaphragm cups allows a motor with a rotating shaft to actuate the diaphragm cups in a clockwise or counterclockwise direction, which provides separate control of the output. This improves dose metering and therefore output consistency, while also improving longevity by isolating the liquid from the air in the pump. Furthermore, a single motor can provide synchronized air and liquid distribution. The liquid diaphragm cup, shown as the third diaphragm cup, is preferably smaller than each of the two air diaphragm cups, shown as the first and second diaphragm cups. The pump outputs a separate vapor of liquid and air in a parallel pair of tubes connecting from the air conduit 141 and the liquid conduit 142. The separate vapors have flows with separate metered amounts and rates.

Figure 16 shows air and liquid flow within the conduit with arrows of various styles.

As seen in Figures 17-21, the jet stem has a lower end with a swivel connection. The lower end of the stem has a barrel 200. The barrel 200 is formed as a tube and has a barrel inner sidewall 203 at the barrel inner edge 202. The barrel lower end 201 is concave while the barrel inner edge 202 is flush with the barrel 200. The barrel outer edge 204 and the barrel inner edge 202 define a tubular shape. At the barrel inner edge 202, a first vertical alignment slot 205 and a second vertical alignment slot 206 extend inwardly into the barrel cavity 207. The barrel inner sidewall 203 has a small barrel inner sidewall 208 and a large barrel inner sidewall 212 that are separated at the first vertical alignment slot 205 and the second vertical alignment slot 206. The inner sidewall 208 of the smaller barrel has a smaller surface area than the inner sidewall 212 of the larger barrel.

The first ramp 210 begins at a first ramp starting edge 211 at the inner edge 202 of the barrel. The first ramp 210 extends spirally downward at the first vertical alignment slot 205 to a first ramp lower edge 213. Similarly, the second ramp starting edge 215 defines the starting location of the second ramp 214. The second ramp 214 terminates at a second ramp lower edge 216 where the second ramp lower edge 216 meets the second vertical alignment slot 206. The second ramp 214 also has a spiral shape and is in the same one direction as the first ramp 210.

The first retention protrusion 221, the second retention protrusion 222, the third retention protrusion 223, the fourth retention protrusion, the fifth retention protrusion 225, and the sixth retention protrusion 226 extend from the inner sidewall 212 of the larger barrel and extend from the barrel cavity 207. Similarly, the seventh retention protrusion 227, the eighth retention protrusion 228, the ninth retention protrusion 229, and the tenth retention protrusion 230 extend outwardly from the inner sidewall 208 of the smaller barrel and extend outwardly from the barrel cavity 207. The barrel cavity has an inner surface with a first tube socket 217 and a second tube socket 218. The first tube socket receives the first tube and the second tube socket receives the second tube.

As seen in FIG. 18, the first tube extension 248 fits into the first tube socket 217 and the second tube extension 249 fits into the second tube socket 218. The first tube extension seal 245 and the second tube extension seal 247 can be formed as O-rings that fit into grooves in the first tube extension 248 and the second tube extension 229. The first shaft and the second shaft have connecting shaft tips 250 that engage the sockets. The first conduit 219 and the second conduit 220 extend from the first tube socket 217 and the second tube socket 218 through the first tube extension 248 and the second tube extension 249.

The pivot tip slots receive the retention protrusions. There are 10 protrusions and 12 slots. When the first retention protrusion 221 fits into the first pivot tip slot 251, the second retention protrusion 222 engages the second pivot tip slot 252. The third retention protrusion 223 engages into the third pivot tip slot 253. The fourth retention protrusion 224 extends into the fourth pivot tip slot 254. The fifth retention protrusion 225 engages into the fifth pivot tip slot 255. The sixth retention protrusion 226 engages into the sixth pivot tip slot 256. However, the seventh retention protrusion 227 enters into the eighth pivot tip slot 258 because the first vertical alignment slot 205 does not have a protrusion thereon. The seventh pivot tip slot does not receive a protrusion because it is adjacent to and aligned with the first vertical alignment slot 205. The eighth retention protrusion 228 enters the ninth pivot tip slot 259. The ninth retention protrusion 229 engages the tenth pivot tip slot 260. The tenth retention protrusion 230 engages the eleventh pivot tip slot 261. The twelfth pivot tip slot does not engage any protrusion because it is aligned with the second vertical alignment slot 206. Optionally, the vertical alignment slots can receive protrusions so that each protrusion is received in each slot, but that is not the best mode.

Optionally, the swivel stop 231 between the first swivel tip slot 251 and the tenth swivel tip slot 260 limits the rotation to less than 180°. There, the second alignment pin 243 and the first alignment pin 242 abut the swivel stop 231. The first alignment pin engages the first ramp 210 and the second alignment pin 243 engages the second ramp 214. The first alignment pin 242 can be a circular segment to match the shape of the vertical alignment slot. The first alignment pin 242 and the second alignment pin 243 engage the pair of slots and the swivel base 241 rotates relative to the connecting shaft 270. In this way, the first extension tube 248 and the second extension tube 249 automatically engage the first tube socket 217 and the second tube socket 218. The angular length of the first beveled portion can be approximately 45°, and the angular length of the second beveled portion can be approximately 45°. Thus, the connecting shaft tip 250 rotates relative to the connecting shaft 270. The connecting shaft 270 is sized to engage the inner sidewall 203 of the barrel. The inner sidewall 203 of the barrel has a diameter slightly larger than the diameter of the connecting shaft 270.

The swivel extension 263 extends upward from the swivel base 241 and can be formed integrally with the swivel base 241. Similarly, the swivel stop 231 can be formed integrally with the connecting shaft 270 and the swivel tip slot. The barrel socket 209 extends upward to the barrel cavity 207. The connection does not require visual inspection. When the user presses the connecting shaft tip upward, the user will feel the first alignment pin 242 engage the ramp or first vertical alignment slot and the second alignment pin 243 engage the ramp or second vertical alignment slot.

The connecting shaft tip 250 thus provides a first swivel nipple 133 that extends beyond the first tube extension seal 245 and a second swivel nipple 134 that extends beyond the second tube extension seal 247. The connecting shaft tip 250 may also have a swivel socket flange 136. The swivel socket flange may have an extended first alignment pin 242 and a second alignment pin 243. The swivel socket flange 136 is preferably solidly formed with the alignment pin. The alignment pins extend outwardly away from each other at an angle other than 180°. The swivel base 241 may have a swivel socket flange 136. The swivel base 241 connects to a pair of tubes that pass through the connecting shaft 270. The second tube extension conduit 246 has a rigid portion at the second swivel nipple 134 and can be connected to a flexible elastomeric tube, such as polyethylene, that can be rotated or twisted. The polyethylene tube is held in a loose configuration within the connecting shaft 270 so that it can rotate with the swivel base 241.

As seen in FIG. 21, the first flexible tube 274 and the second flexible tube 275 fit onto the pivot tip shaft 272, which has a press-fit taper 273. The press-fit taper 273 fits onto the connecting shaft 270 in a pivot connection. The pivot tip base 241 includes a first alignment pin 242 and a second alignment pin. The pivot tip base 241 is rigidly formed with the pivot tip shaft 272 and the press-fit taper 273. The flexible tubes have some slack, which allows the flexible tubes to twist up to 180° inside the connecting shaft 270.

As seen in FIG. 22, the jet extension 24 has a jet mounting shaft 26 with male threads that engage with the mounting shaft nut female threads 281 formed on the mounting shaft nut upper end 292 located on the upper portion of the mounting shaft nut 27. A mounting shaft nut lower extension 284 extends downwardly from the mounting shaft nut upper end 292. The mounting shaft nut lower extension 284 is preferably threaded to receive the mounting shaft nut retainer 290. As the mounting shaft nut 27 rotates about the jet mounting shaft 26, the mounting shaft nut retainer 290 rotates about the mounting shaft nut 27. The mounting shaft nut retainer 290 rotates on the male threads of the mounting shaft nut lower extension 284 to descend to abut against the pump outlet opening flange 139. The lower barrel flange 288 is formed below and preferably symmetrical to the pump outlet opening flange 139. The sensor cable 282 passes through a sensor cable slot 283 and enters the jet mounting shaft 26 at the lower end of the mounting shaft nut 291.

As seen in FIG. 23, the assembly of the jet extension 24 to the mixer pump housing top 49 is further completed. The barrel 200 forms the pump outlet opening 42 in the mixer pump housing top 49. The mounting shaft nut lower extension 284 has external mounting shaft nut threads 280 that receive the mounting shaft nut retainer 290.

The swivel socket circlip 135 is mounted to the mounting shaft nut retainer 290. The swivel socket circlip 135 has a swivel socket circlip top slot 285 and a swivel socket circlip bottom slot 286. A circlip slot ridge 289 protrudes between the swivel socket circlip top slot 285 and the swivel socket circlip bottom slot 286. The swivel slot circlip top slot 285 clamps the mounting shaft nut retainer 290 to the pump outlet opening flange 139 and the bottom barrel flange 288 by clipping the pump outlet opening flange 139 and the bottom barrel flange 288 together into the swivel slot circlip top slot 285. The barrel 200 has a pump outlet opening flange 139 and a bottom barrel flange 288 with a pump outlet opening slot 287 formed therebetween. The pump outlet opening slot 287 receives the circlip slot ridge 289, and the swivel slot circlip bottom slot 286 receives the bottom barrel flange 288.

The user first places the jet extension 24 on the countertop on the top surface of the countertop. The user then rotates the mounting shaft nut 27 to the bottom surface of the countertop and tightens it. With the jet extension 24 secured to the countertop, the user then orients the barrel 200 to face upward. The user then pushes the jet extension 24 into the pump outlet opening 42. The jet extension 24 fluidly connects with the pump outlet opening 42. The user then rotates the mounting shaft nut retainer 290 until it contacts the pump outlet opening flange 139. The user then installs the swivel slot circlip 135 by sliding it over the mounting shaft nut retainer 290 and the pump outlet opening flange 139. The swivel socket circlip 135 is strong enough to hold the entire lower portion of the mixer pump.

As seen in FIG. 24, the bottle is then installed. The bottle has an adapter gasket 72 formed of an elastomeric material that seals against the pump housing. The adapter gasket 72 is attached to the bottle adapter 35. The bottle adapter 35 additionally includes an adapter hook 86. The bottle has an adapter protrusion 36 that engages with the bottle receiving connection 300.

As seen in FIG. 25, the bottle is placed in the bottle receiving connection socket 307 of the bottle receiving connection 300. The bottle receiving connection 300 can be formed with a bottle receiving connection socket wall 306 extending downward from the bottom surface 311 of the bottle adapter receiving frame 65 of the bottle adapter receiving portion. The bottle receiving connection socket wall 306 has a bottle receiving connection inner wall 308 extending upward to the bottle receiving socket upper wall 310. The bottle receiving connection inner wall 308 has a bottle adapter suction funnel 83. The bottle adapter suction funnel 83 leads to a bottle adapter retention ridge 84 and then to a bottle adapter retention slot 89. The bottle adapter retention slot 89 receives the bottle adapter protrusion 36 that is retained in the bottle adapter retention slot 89. Preferably, at least one pair of the bottle adapter retention slots 89 is utilized to retain a pair of adapter protrusions 36.

The inlet nozzle tip 309 projects downwardly from the top wall 310 of the bottle receiving socket. The mixer pump 40 has a mixer pump housing 41. The mixer pump housing 41 includes a bottle adaptor receiving frame 65 having a bottle adaptor receiving frame underside 311. The bottle adaptor receiving frame underside 311 is held to the mixer pump housing 41 at a bottle adaptor receiving frame connector 312.

The inlet nozzle tip 309 enters the adapter gasket 72 at a circular adapter gasket opening at the top surface of the adapter gasket 72. Preferably, the inlet nozzle tip 309 includes an inlet nozzle tip first conduit 301 formed as an arcuate conduit and an inlet nozzle tip second conduit 302 formed as an arcuate conduit and oriented at 90° to the inlet nozzle tip first conduit 301. The inlet nozzle tip third conduit 303 is preferably an arcuate conduit oriented at 90° to the inlet nozzle tip second conduit 302. The inlet nozzle tip fourth conduit 304 is preferably an arcuate conduit oriented at 90° to the inlet nozzle tip third conduit 303. The fifth conduit 305 at the inlet nozzle tip is preferably a circular conduit formed between the first conduit 301 at the inlet nozzle tip, the second conduit 302 at the inlet nozzle tip, the third conduit 303 at the inlet nozzle tip, and the fourth conduit 304 at the inlet nozzle tip.
