[0195] The following embodiments include devices and techniques for reducing, mitigating, or preventing biofilm in piping installations. Piping installations may include pipes, faucets, bathtubs, showers, water softeners, water heaters, toilets, or other installations. The term "piping installation" refers to equipment connected to a piping system in a house, building, or other structure. The term "bathroom installation" may more specifically refer to the various types of piping installations found in bathrooms. The term "kitchen installation" may more specifically refer to the various types of piping installations found in kitchens.

[0196] Figure 1An example biofilm prevention device 100 is illustrated, removably connected to a washbasin or sink 106, or another ductwork device. The biofilm prevention device 100 may include a supply container 110, a disinfectant generator (e.g., an ozone generator 111 or a hydrogen peroxide generator), a water source 112, a power source (e.g., a battery 113 or an electrical outlet), and a delivery conduit 103. The sink 106 may be mounted to a countertop 104 and includes a nozzle or faucet 109. The sink 106 may include an outlet 102 connected to a tailpipe 105, which may be referred to as a drain pipe, and extends downstream of the outlet 102. Additional, fewer, or different components may be included. As shown in other embodiments, the biofilm prevention device 100 may be connected to the ductwork device at any point downstream of the ductwork device. The biofilm prevention device 100 may be integrated with the ductwork device. Faucets, bathtubs, showers, water softeners, water heaters, or toilets may include biofilm prevention devices 100.

[0197] Supply container 110 is configured to store one or more materials for forming a disinfectant. The disinfectant generator is configured to generate a disinfectant from one or more materials from supply container 110. The one or more materials for forming the disinfectant may include water, gases (e.g., oxygen, nitrogen), air, and / or other materials. The disinfectant may contain wholly or partially hydrogen peroxide or silver ions. The disinfectant generator may include a pump, charger, or other power source supplied with electricity. The disinfectant generator may receive input from water source 112. Water may be mixed with the disinfectant.

[0198] In some embodiments, the disinfectant generator is an ozone generator 111, which produces ozone gas or O2. 3 Ozone gas can react with or oxidize bacteria, organic materials, or other contaminants. In some examples, water is supplied from supply container 110 and ozone generator 111 generates ozone gas from the water. Ozone gas can be generated using a corona charger or corona discharge (e.g., spark discharge). Ozone can be generated from air and / or water. A high voltage can be applied to the corona charger to induce a corona discharge, thereby electrically breaking down the water or air near the corona charger. The corona charger can include a charge or voltage exceeding the dielectric strength of water and / or air, thereby breaking down the water and / or air into one or more components and ozone gas.

[0199] The power supply is configured to provide power to the disinfectant generator. The power supply can be an AC source (e.g., the biofilm prevention device 100 may include a power cord). The power supply can also be a DC source, such as... Figure 1 Battery 113 in the middle.

[0200] In some embodiments, as a supplement to or alternative to a disinfectant generator, induced biogeneration can introduce microorganisms into the pipe fixtures (e.g., outlet 102 and / or tailpipe 105). The microorganisms can release enzymes that can degrade biofilms. These may include various enzymes such as glycosidases, proteases, and deoxyribonucleases (DNases). These enzymes can degrade different components in extracellular polymeric substances (EPS), specifically polysaccharides, proteins, and eDNA. This destabilizes the biofilm by altering its structure and increasing antibiotic permeability. Induction can be achieved by adding chemicals, detergents, radiation, temperature, etc. By using an enzymatic detergent containing a mixture of proteases, D-Nase I, amylase, and cellulose, the biofilm EPS can be destabilized and biofilm removal efficiency improved.

[0201] Delivery pipe 103 is configured to deliver disinfectant from a disinfectant generator to the biofilm. Delivery pipe 103 may include a flexible tube made of rubber or another flexible material. Delivery pipe 103 may include threaded connectors at either or both ends of pipe 103. One connector may be connected to biofilm prevention device 100, and the other end may be connected to outlet 102, tailpipe 105, or to a piping system as described below. Delivery pipe 103 supplies disinfectant to outlet 102 or other locations in the piping system. The disinfectant may degrade or slow biofilm growth. The disinfectant may remove biofilm from the piping system.

[0202] In similar Figure 1 In the example, the delivery pipe 103 is configured to pass through the discharge port 102 and connect to the upstream side of the tailpipe 105. Alternatively or additionally, in conjunction with... Figure 2 In similar examples, delivery pipe 103 may be configured to be connected to the downstream side of tailpipe 105 via piping system 108.

[0203] Figure 2 An example biofilm prevention device 100 is illustrated, connected to a piping system 108 for a washbasin or sink 106. The biofilm prevention device 100 of this embodiment can be connected to or integrated into any piping system. The biofilm prevention device 100 may include any of the components described above (e.g., supply container 110, disinfectant generator (e.g., ozone generator 111), water source 112, power source (e.g., battery 113)). The biofilm prevention device 100 is connected to the piping system 10 via a delivery pipe 103, for example, at a tailpipe 105 extending from the outlet 102. Additional, fewer, or different components may be included.

[0204] The delivery pipe 103 may include a valve 128 configured to open or close the supply of disinfectant to the tail pipe 105 for preventing biofilm formation. The valve 128 may include a mechanical knob or lever for operating the valve. The valve 128 may include a motor or solenoid operated by a controller (e.g., controller 400 described herein).

[0205] Similarly, piping system 108 may include a valve for closing tailpipe 108 or a P-trap during the biofilm prevention process. Valve 129 may include a mechanical knob or lever for operating valve 129. Valve 129 may include a motor or solenoid operated by a controller (e.g., controller 400 described herein). The controller may close valve 129 in response to operation of biofilm prevention device 100 or input from a user activating biofilm prevention device 100. Valve 129 prevents the downstream escape of disinfectants or other substances during the biofilm prevention process.

[0206] Furthermore, the discharge port 102 can be sealed during biofilm prevention. That is, the user can insert the tube 103 into the discharge port to initiate the biofilm prevention process, and then place the cap 127 on the discharge port. Alternatively, this cap 127 can be automatically applied or removed by the controller according to a timer.

[0207] In any of these examples, the controller can execute a disinfection cycle with multiple phases. The process can begin and end at any phase and be executed in any order. In the example sequence, the first phase involves the normal operation of the appliance, i.e., draining water without a biofilm prevention process. In some examples, the controller is not involved in causing the first phase. In other examples, the controller starts the pump to supply water to tank 106.

[0208] In the second stage, the biofilm prevention device 100 supplies disinfectant to the appliance. The controller can open a valve to allow disinfectant and water to leave the supply container 110 and be supplied to the piping system via the delivery pipe 103. Alternatively or additionally, the controller can operate a pump to allow water to leave the supply container 110 and be supplied to the piping system via the delivery pipe 103.

[0209] In the third stage, a cap is applied to the discharge port and / or the piping system is shut off to contain the disinfectant within the discharge port. For example, a controller can close a valve blocking discharge port 105. This valve can be integrated with the cap 127. The controller can actuate a solenoid or motor to close discharge port 105.

[0210] In the fourth stage, the valves in cover 127 and / or the piping system are opened. As in the third stage, the controller can actuate a solenoid, motor, or other device to open the passage to outlet 105.

[0211] Different time periods can be applied to each stage. In one example, the second, third, and fourth stages last approximately 20 to 30 minutes. For instance, the controller could execute the second stage, then start a timer and continue for a predetermined time, and when the timer reaches its predetermined duration, continue executing the third stage. Similarly, the controller could execute the third stage, then start a timer and continue for a predetermined time, and when the timer reaches its predetermined duration, continue executing the fourth stage.

[0212] Figure 3 Another example of a biofilm prevention device 100 is illustrated. In this embodiment, the biofilm prevention device 100 includes a powered scrubber 131 (or alternatively, a sandblasting machine), which may include a pump 132, a water source 112, and a power source 123, either internally or externally. Additional, different, or fewer components may be included.

[0213] Power source 123 may include a battery (e.g., battery 113). Power source 123 may include an engine that uses a fuel source (e.g., gasoline, propane, compressed natural gas). Power source 123 may include an air tank or other compressed air source.

[0214] The biofilm prevention device 100 can be placed in any of the configurations described herein that include a delivery pipe 103, which is configured to connect to the upstream side of the tailpipe 105 via an outlet 102 or to the downstream side of the tailpipe 105 via a piping system 108. The biofilm prevention device 100 can be a modular or portable unit located near the outlet 102, into which the delivery material is placed or onto an openable port on the piping system 108.

[0215] After installation, the user can activate the biofilm prevention device 100 to start the power scrubber 131. The pump 132 of the power scrubber 131 is powered via a power source 123 to generate water pressure, which then supplies water from the water source 112 to the outlet 102 or the tailpipe 105. Even in the absence of ozone or another substance, the high-pressure water can prevent biofilm formation. In some embodiments, ozone or another material may be combined with the water in that embodiment.

[0216] Figure 4Another example biofilm prevention device 100, including a chemical sprayer 135, is illustrated. The chemical agent can be a chemical substance, such as a solution containing one or more of hydrogen peroxide, hypochlorous acid, iodine, bromine, chloramine, chlorine dioxide, peracetic acid, quaternary ammonium, tetraacetylethylenediamine, phenol, isopropanol, sodium carbonate, peroxide hydrate, tetraacetylethylenediamine, ethanol, sodium hypochlorite, octanoic acid, or sodium chlorite. According to any example herein, including manual and / or automatic operation and / or disinfectant circulation, a mixer 134 can mix water from water source 112 for distribution via the chemical sprayer 135 to outlet 102 or piping system 108.

[0217] Figure 5 An example biofilm prevention device 100 is illustrated, which is connected to multiple appliances (e.g., bathtub 140 or hot tub, shower 143, sink 144, and / or external drain 142). The biofilm prevention device 100 can be integrated in a central location. The central location can be located within a wall and connected to a piping system for the multiple appliances. The central location can be, for example, located in a basement or utility room, and can be connected to or otherwise integrated with a water heater, water softener, or greywater system. Additional, different, or other features may be included.

[0218] Figure 6 An example of a piping system is provided, which includes a biofilm prevention pipe 115 for use in a sink 106, such as one connected to a tailpipe 105 and a P-trap 119. For example, a biofilm prevention device 100 may be connected to a bathtub 140 or hot tub, a shower 143, a sink 144, and / or an external drain 142. The external drain 142 may be located in the floor (e.g., for a basement or laundry room) or in a swimming pool. The shower 143 may include a shower head configured to spray water and a drain. The bathtub 140 may include a faucet and / or one or more nozzles and a partially enclosed container including the drain. Additional, different, or fewer components may be included.

[0219] The piping system 108 described in this document can be connected to Figure 5 Any combination of appliances. Piping system 108 is connected to the appliances and delivers disinfectant to them.

[0220] The piping system 108 may include at least one valve configured to release disinfectant into at least one appliance. For example, the valve may be included in the disinfectant path between the biofilm prevention device 100 and each appliance.

[0221] A controller (e.g., controller 400 described below) can be configured to control each valve according to a schedule. In one example, the valves are controlled in response to user input. In another example, one or more valves are controlled in response to analysis of sensor data. Controller 400 is configured to receive user selection or sensor data and, in response, determine one or more valve commands. Sensor 321 can be the same or a different type of sensor.

[0222] Sensor data can be received by various sensors. Sensors may include flow sensors, environmental sensors, water level sensors, or other types of sensors. A flow sensor can measure the amount of water flowing through outlet 102 or dispensed by nozzle 109. Controller 400 can determine whether a threshold water volume has been dispensed and, in response, initiate a biofilm prevention process. Environmental sensors may include temperature sensors, humidity sensors, and / or other types of sensors configured to detect conditions at outlet 102. Controller 400 can determine whether conditions for biofilm formation have been present (e.g., for a predetermined duration) and, in response, initiate a biofilm prevention process. A water level sensor can determine whether water has flowed back into outlet 102 (e.g., for a predetermined duration) and, in response, initiate a biofilm prevention process.

[0223] Figure 7 An example controller for a biofilm prevention system is illustrated. Controller 400 may include processor 300, memory 352, and communication interface 353 for interface with a device or the Internet and / or other network 346. In addition to communication interface 353, sensor interfaces may be configured to receive data from sensors described herein or from any source for analyzing water properties or the operation of the apparatus described herein. Components of control system 400 may communicate using bus 348. Control system 400 may be connected to a workstation or another external device (e.g., a control panel) and / or database to receive user input, system characteristics, and any values ​​described herein.

[0224] Optionally, the control system 400 may include an input device 355 and / or sensing circuitry that communicates with any sensor. The sensing circuitry receives sensor measurements as described above. The input device 355 may include a switch, a touchscreen coupled to or integrated with a mirror, a keyboard, a microphone for voice input, a camera for gesture input, and / or other mechanisms.

[0225] Optionally, the control system 400 may include a drive unit 340 for receiving and reading a non-transitory computer medium 341 having instructions 342. Additional, different, or fewer components may be included. The processor 300 is configured to execute the instructions 342 stored in memory 352 for performing the algorithms described herein. The display 350 may be supported by any of the components described herein. The display 350 may be combined with a user input device 355.

[0226] Figure 8 The diagram illustrates a flowchart of the controller for a biofilm prevention system. The actions in the flowchart can be performed by any combination of the control system 400, network devices, or servers. One or more actions may be performed by appliances. Additional, different, or fewer actions may be included.

[0227] In action S101, the controller 400 can perform the first stage of normal operation of the appliance, namely, discharging water without a biofilm prevention process. For example, the piping device can be operated using one or more functions of the piping device. In the case of the sink 106 of the washbasin, the faucet (valve) can be operated to open and close the water dispensed from the faucet, regulate the volume of water dispensed from the faucet, and / or regulate the temperature of the water dispensed from the faucet.

[0228] In action S103, the controller 400 can perform the second stage, whereby the biofilm prevention device 100 supplies disinfectant to the appliance. The controller 400 can open the outlet of the biofilm prevention device 100. The controller 400 can activate the disinfectant generator to produce disinfectant. The controller 400 can open the valve for the delivery pipe 103 to distribute the disinfectant into the piping device.

[0229] In action S105, controller 400 may perform a third stage, in which a cap or covering is applied (closed) to the discharge port and / or piping system via a solenoid or other mechanical device to seal the disinfectant within the discharge port. In action S105, controller 400 may perform a fourth stage, in which the cap and / or piping system is opened.

[0230] Action S107 can be performed by the reverse action of action S103, for example, the controller 400 opening the cover and / or the reverse action of the piping system. The controller 400 can start a timer to measure the amount of time the disinfectant has been in the piping system. Different types of disinfectants can be assigned different amounts of time. The controller 400 can access the time preset for the timer based on the disinfectant used. When the controller 400 determines that the disinfectant 400 has been exposed to the drain or other parts of the piping system, the controller 400 executes action S107 to open the drain.

[0231] Figure 9 An exemplary internal automated biofilm prevention device for a piping system is illustrated. The biofilm prevention device may include a robotic system 150, which includes at least one robotic scrubber 160 corresponding to a robotic scrubber area 153, at least one movable guide member 152, and a drive mechanism. The robotic system 150 may include internal components located inside a tailpipe 105 and external components located outside the tailpipe 105. The external components may be enclosed by a housing 151. Additional, different, or fewer components may be included.

[0232] The robotic scrubber area 153 is configured to be cleaned by at least one robotic scrubber 160. For example, the robotic scrubber area 153 may have a different diameter than the rest of the tailpipe 105. The robotic scrubber area 153 may include a surface of a different type (e.g., textured) than the rest of the tailpipe 105.

[0233] Figure 10 and Figure 11 An internal automated biofilm prevention device is illustrated. A robotic scrubber 160 can be supported on the inner side of the discharge pipe 105 via a movable guide member 152. The movable guide member is close to (e.g., in contact with or within a small distance of the outer side of the discharge pipe) and supported on the outer side of the discharge pipe, and configured to guide the robotic scrubber 160 inside the pipe. For example, a transport track 156 can support a carrier 155. The carrier 155 can be a magnet, an electromagnet, or any device configured to apply force to the robotic scrubber 160 via the tailpipe. The carrier 155 can include one or more grooves, ridges, or channels to travel along the transport track 156 in one or more directions around the outer side of the tailpipe 105.

[0234] A controller (e.g., controller 400) may be included on the outer side of the discharge duct (external controller implementation) or integrated with the robotic scrubber 160 (internal controller implementation). For example, Figure 10 In the illustrated embodiment of the external controller, the controller 400 can be installed on one side of the discharge pipe 105 or below the water tank 106. For example... Figure 12 In the illustrated implementation of the internal controller, the controller 400 can be integrated into the body of the robot scrubber 160.

[0235] In an alternative not shown, a manual handle is connected to a drive mechanism. The manual handle allows the user to move the movable guide member 152 along a predetermined path. The manual handle can be a crank or a lever, and the drive mechanism can include gears or cables coupled to the movable guide member 152.

[0236] The controller 400 is configured to generate commands for driving the mechanism, causing the movable guide member 152 to move along a predetermined path. In an external controller implementation, the movable guide member 152 moves across a conveyor track 156. The predetermined path can be set by the path of the conveyor track 156. In an internal controller implementation, the predetermined path can be set by the controller 400.

[0237] The drive mechanism is configured to move a movable guide member within a predetermined path. The predetermined path may include at least one circumferential path parallel to the circumference of the tailpipe 105. The circumferential direction is perpendicular to the flow direction through the tailpipe 105. The predetermined path may also include at least one horizontal direction parallel to the flow direction through the tailpipe 105.

[0238] The controller 400 can receive instructions from users or external devices, and can also send commands to the movable guide member 152 and / or the robotic scrubber 160. Commands from users can be received locally by the robotic system 150 via buttons, touchscreens, or keypads mounted or electrically connected to the robotic system 150. Commands from users can also be received from mobile devices via wireless signals (e.g., cellular, Bluetooth, Wi-Fi, etc.).

[0239] In some examples, controller 400 may generate commands for the movable guide member 152 and / or robotic scrubber 160 based on sensor data. The sensor data may describe the presence or quantity of biofilm or conditions associated with biofilms described in other embodiments.

[0240] exist Figure 10 In this configuration, the controller 400 is connected to the carrier 155 via a cable or tether 154. The carrier 155 may be supported by a transfer rail 156 on the outer side of the tail tube 105. The tether 154 between the movable guide member 152 and the drive mechanism may include one or more wires that transmit commands and power from the controller to the robotic scrubber 160.

[0241] exist Figure 11In this embodiment, the controller 400 is integrated into the robotic scrubber 160. The controller 400 can provide commands to move the carrier 155 (on the outer side of the tail tube 105) and / or the robotic scrubber 160 (on the inner side of the tail tube 105) to mate or dock with a charging station. The charging station is coupled to the carrier 155 and configured to charge the battery of the robotic scrubber 160. The battery supplies power to the drive system of the robotic scrubber 160. The controller 400 can cause the robotic scrubber 160 to move to the charging station after a set amount of running time, at a certain time of day, or on a certain day of week. The controller 400 can also cause the robotic scrubber 160 to move to the charging station in response to a battery charge level determined by a battery charge sensor.

[0242] Figure 12 An example robotic scrubber 160 for use in an internal automated biofilm prevention device is illustrated. The robotic scrubber 160 may include a housing 161, at least one arm 162, at least one cleaning component 163, and at least one drive component 164. Additional, different, or fewer components may be included.

[0243] The housing 161 may be a plastic or metal housing that encloses other components. At least one arm 162 extends from the housing 161 to support at least one cleaning member 163. The at least one cleaning member 163 may include absorbent material, abrasive material, scouring pad, or another material suitable for scrubbing biofilm or other microorganisms from inside the tailpipe 105.

[0244] At least one drive member 164 includes a gear, belt, or pulley that follows a path 169 in the scrubber region 153. The path 169 may be realized by a groove, slot, or track in the tailpipe 105.

[0245] Figure 13 Another example robotic scrubber for an internal automated biofilm prevention device is illustrated, which includes a tensioning member 166. The tensioning member 166 may include a spring or another biasing member that can provide force to support the robotic scrubber 160 within the tail tube 105. The robotic scrubber 160 may be configured to extend outwards to be supported by the tail tube 105.

[0246] In another example, tail tube 105 may include a helical path (including a sloping path with multiple turns around the inner circumference of tail tube 105). Robotic scrubber 160 may travel vertically within tail tube 105 circumferentially along the helical path.

[0247] Figure 14An example magnetic stop system or stop assembly 170 for a drain outlet of sink 106 is illustrated. Stop assembly 170 can be applied to any drain outlet and / or any appliance described herein. Stop assembly 170 may include a magnetic guide 175, a stop 171, and at least one magnetic foot 173 supported by a guide rail 172. Additional, different, or fewer components may be included.

[0248] The stop assembly 170 may also include a drive system for changing the position of at least one driven magnet 174. The magnet guide 175 includes a track and at least one driven magnet 174 slidably engaged with and positioned to provide a magnetic field. The track may include a slot into which the magnet 174 can slide. The magnet 174 may be positioned by a motor or solenoid operated by the controller 400. The motor or solenoid may be connected to the magnet via an additional drive element such as a gear or belt as a drive system.

[0249] The stop 171 is configured to at least partially seal the discharge port 102. At least one magnetic foot 173 is coupled to the stop and positioned in a magnetic field to move the stop under the force exerted by the magnetic field. In some examples, the driven magnet 174 includes an upper driven magnet located above the at least one magnetic foot 173 and a lower driven magnet located below the at least one magnetic foot 173. The at least one magnetic foot 173 includes three magnetic feet spaced apart in a radial direction.

[0250] The drive system is configured to receive an input indicating the stop position. The controller 400 can be configured to generate an input for the stop position. Example stop positions can be open or closed. In the open position, stop 171 does not seal the discharge port, allowing water and other materials to escape from tailpipe 105. In the closed position, stop 171 seals the discharge port, preventing water and other materials from escaping downwards along tailpipe 105. Alternatively, stop 171 can partially seal the discharge port, effectively preventing virtually all water from escaping downwards along tailpipe 105.

[0251] The controller 400 is configured to cause the drive system to move at least one driven magnet 174 from a closed position to an open position, in which the stop 171 moves under the action of the magnetic field to unseal the discharge port.

[0252] The controller 400 can generate a magnet command that moves the driven magnet 174 between an open and closed position. The command can be generated in response to input (triggering) from a user interface, a timer, or a sensor. The user interface is electrically connected to the controller 400. Input can be generated in response to the user interface. A timer can trigger an input when a specific time or time of day has elapsed. Sensors can trigger the movement of the magnet 174 based on flow devices or sensors, environmental sensors, water level sensors, or other types of sensors. A flow sensor can measure the amount of water flowing through the outlet 102 or dispensed by the nozzle 109. The controller 400 can determine whether a threshold amount of water has been dispensed and, in response, close the stop assembly 170. Environmental sensors can include temperature sensors, humidity sensors, and / or other types of sensors configured to detect conditions at the outlet 102. The controller 400 can determine whether conditions for biofilm formation (e.g., for a predetermined duration) are present and, in response, close the stop assembly 170. The water level sensor can determine whether water has flowed back into the discharge port 102 (e.g., for a predetermined amount of time) and close the stop assembly 170 in response.

[0253] Figure 15 An example disposable sleeve system 180 is illustrated, which has a mechanically operated disposable sleeve 181 for a discharge pipe 105. The disposable sleeve system 180 may include a compartment 183, a seal 184, and a locking ring 182. Additional, different, or fewer components may be included.

[0254] Compartment 183 is configured to accommodate a section of disposable sleeve material outside the discharge duct 105. The disposable sleeve material 181 may be plastic, such as polyethylene. Compartment 183 may be a sealing element for a roll of disposable sleeve material 181. Compartment 13 may include a cover or other removable portion for loading or unloading disposable sleeve material 181.

[0255] A seal 184 is positioned at a first end of the discharge conduit 105 and configured to dispense disposable material 181 into the discharge conduit 105. The seal 184 allows a waterproof or partially waterproof path for the disposable sleeve material 181 to be advanced from the outside of the discharge conduit 105 to the inside of the discharge conduit 105. The portion of the disposable sleeve material 181 advanced into the discharge conduit 105 may be referred to as the discharge section. The discharge section covers the interior of the discharge conduit 105 to prevent biofilm formation.

[0256] A locking ring 182 is positioned at the second end of the discharge conduit and configured to connect the discharge section of disposable sleeve material to the discharge conduit 105. The disposable sleeve system 180 may also include a groove configured to receive and support a used portion of the disposable sleeve material 181. The disposable sleeve system 180 may also include a cutting device configured to remove a portion of the disposable sleeve material 181. The cutting device may be engaged with or proximate to the locking ring 182. A wiper may be engaged in or adjacent to the locking ring 182 (below the locking ring 182) to remove biological material (e.g., biofilm) from the disposable sleeve material 181.

[0257] The user can grasp a portion of the disposable cannula material 181 to advance it. To remove old or used material, the user can press the cutting device or push the disposable cannula material 181 against it. The user can pull the disposable cannula material 181 to remove a new disposable cannula material from the roll. The user can press the disposable material 181 against the locking ring 182 or otherwise close the locking ring 182 to hold the new disposable cannula material 181 in place, thereby further preventing biofilm formation.

[0258] As an alternative to this manual implementation, the disposable cannula system 180 may include an actuator for advancing disposable cannula material. The actuator may be a handle or knob that receives manual input. Alternatively, an electronic system may advance the disposable cannula material 181.

[0259] Figure 16 The illustration shows an example automated disposable sleeve system 180 for use with discharge pipe 105. (Except for information about...) Figure 15 In addition to the components described, the disposable sleeve system 180 may include a drive mechanism 185 and a controller 400, the drive mechanism 185 being configured to advance a discharge segment of disposable sleeve material into a discharge conduit 105, and the controller 400 being configured to generate commands for the drive mechanism to advance a discharge segment of disposable sleeve material 181 into a discharge conduit.

[0260] Controller 400 can be configured to control the actuation of disposable sleeve material 181 based on one or more inputs. Inputs can be a schedule. Controller 400 can compare the current time with a predetermined time interval, a time of day, or a day of week, and advance the disposable sleeve material 181 based on that comparison. Controller 400 can be configured to advance the disposable sleeve material based on sensor data. Sensor data describes the environment of discharge conduit 105, biofilm formation in discharge conduit 105, or use of discharge conduit 105. Controller 400 is configured to receive user selections or sensor data and, in response, determine one or more disposable sleeve commands. Sensor data can be received by a variety of sensors. Sensors can include flow sensors, environmental sensors, water level sensors, or other types of sensors. Flow sensors can measure the amount of water flowing through discharge port 102 or dispensed by nozzle 109. Controller 400 can determine whether a threshold water volume has been dispensed and, in response, initiate a biofilm prevention process. Environmental sensors can include temperature sensors, humidity sensors, and / or other types of sensors configured to detect conditions at discharge port 102. The controller 400 can determine whether conditions for biofilm formation have been present (e.g., for a predetermined duration) and initiate a biofilm prevention process in response. The water level sensor can determine whether water has flowed back into the discharge outlet 102 (e.g., for a predetermined duration) and initiate a biofilm prevention process in response.

[0261] Figure 17 The illustration shows an example rotatable P-trap assembly 403 for use in a piping system. Figure 18 The illustration shows a side view of a rotatable P-trap assembly. The piping system may include a drain pipe 105, an upstream connection pipe 404, a downstream connection pipe 505, and a P-trap assembly 403. Additional, different, or fewer components may be included.

[0262] A rotatable P-trap can provide shearing action on biofilm that forms inside the P-trap or on other deposits that form along the piping system. This shearing action can disrupt growth or cause the biofilm to separate and drain into the sewer or septic tank system. A rotatable P-trap can also help break up and remove blockages.

[0263] The upstream connecting pipe 404 connects the discharge pipe 105 to the P-trap assembly 403. The downstream connecting pipe 405 connects the P-trap assembly 403 to the sewer or septic tank system of the house or building.

[0264] The P-trap assembly 403 includes one or more joints 402 located between a plurality of trap segments. The joint 402 is a rotatable joint between adjacent trap segments (e.g., between a first trap segment and a second trap segment). The joint 402 may include one or more bearings or other pivotable components.

[0265] The trap section may include a first trap section 403a connected to a drain pipe 105 of a water-consuming appliance (e.g., sink 106) and a second trap section 403b connected to the first trap section 403a and the connecting pipe 404. The first trap section 403a includes a first trap at a first height and the second trap section 403b includes a second trap at a second height. Optionally, a third trap section 403c may be connected between the first trap section 403a and the second trap section 403b and / or a fourth trap section may be connected between the third trap section 403c and the second trap section 403b.

[0266] Figure 18 Examples of water trap sections at different heights are illustrated. Each water trap section may have a different height and / or be positioned at different angles relative to the first connecting pipe 404 and the second connecting pipe 40. The first water trap holds water at a position in the drive mechanism where the second water trap does not hold water.

[0267] In some examples, the P-trap assembly 403 is rotatable. That is, the first trap, the second trap, and / or other traps can be rotated to different heights and angles. The P-trap assembly 403 can be rotated by manual input such as a crank, handle, or knob.

[0268] The drive mechanism 401 is configured to move the first trap section 403a or the second trap section 403b relative to the drain pipe 105 or the connecting pipe 404. The drive mechanism 401 may include a stepper motor or a solenoid. The drive mechanism 401 may be actuated based on a timer or schedule. The drive mechanism 401 may be actuated based on sensor data.

[0269] The controller 400 is configured to generate commands to actuate the drive mechanism. The controller 400 can receive input data for the dynamic P-trap. Input data may include a schedule or sensor data. The controller 400 can compare the current time with a predetermined time interval, a time of day, or a day of week, and rotate the P-trap assembly 403 based on that comparison. Sensor data describes the environment of the discharge pipe, biofilm formation in the discharge pipe, or the use of the discharge pipe. The controller 400 is configured to receive user selection or sensor data and, in response, determine one or more rotation commands. Sensor data may be received by a variety of sensors. Sensors may include flow sensors, environmental sensors, water level sensors, or other types of sensors. Flow sensors may measure the amount of water flowing through the discharge port 102 or dispensed by the nozzle 109. The controller 400 can determine whether a threshold water volume has been dispensed and, in response, initiate a biofilm prevention process. Environmental sensors may include temperature sensors, humidity sensors, and / or other types of sensors configured to detect conditions at the discharge port 102. The controller 400 can determine whether conditions for biofilm formation have been met (e.g., for a predetermined duration) and, in response, initiate the rotation of the P-trap. The water level sensor can determine whether water has flowed back into the drain 102 (e.g., for a predetermined duration) and, in response, initiate the rotation of the P-trap.

[0270] The controller 400 can generate rotation commands for the dynamic P-trap. Rotation commands can include the amount of rotation, the number of rotations, or a specific angle by which one or more traps of the P-trap assembly 403 should move. For example, a rotation command may include a stepper motor angle. In another example, a rotation command may include a current level for an electromagnet in a solenoid that causes the P-trap assembly to rotate. The solenoid may engage gears on a shaft supporting the P-trap assembly. In other words, several alternatives are possible for the drive mechanism 401 to rotate the P-trap assembly 403 in response to rotation commands.

[0271] Figure 19 Another example of a rotatable P-trap assembly is illustrated. In this example, four trap sections and five connectors 402 are shown. Each connector 402 can be independently controlled by a controller 400. Two connectors 402 on either side of the inner P-trap can be actuated by a solenoid or motor to rotate the P-trap.

[0272] Figure 20An example foam separation device 500 is illustrated for preventing the formation of biofilms or other biological materials at the discharge port 102 of a water appliance such as a sink 106. The foam separation device 500 may include a liquid pool chamber 526 and a foam chamber 525 located within and / or downstream (e.g., below) of the discharge pipe 105. Figure 20 In the example, the liquid pool chamber 526 is located below the discharge pipe 105, while the foam chamber 525 is located inside the discharge pipe 105.

[0273] The foam separation device 500 may include at least one inlet and at least one outlet. A connecting pipe 404 and / or a P-trap may be Y-connected to the foam separation device 500 and the discharge pipe 105. Additionally, an air inlet 522 may supply gas (e.g., air) to the liquid tank chamber 526. A foam outlet 524 may remove excess foam, liquid, or air from the liquid chamber 526. Additional, different, or fewer components may be included.

[0274] Foam separation device 500 is configured to foam suspended or dissolved material away from water in discharge pipe 105 by adsorption on the surface of one or more bubbles 527. Adsorption is a process in which solid molecules adhere to the surface of one or more bubbles 527. This process can create a film on the surface of the adsorbent. One of the multiple bubbles 527 floats and passes through liquid pool chamber 526 to float on the water surface, thereby forming foam. Foam outlet 521 may include a skimmer for removing foam. Foam outlet 521 may include suction (e.g., vacuum pressure) to remove foam. Suction may be provided by a pump. Alternatively, the routine of emptying and filling the liquid pool chamber can be used to remove foam.

[0275] Figure 21 An example ultrasonic cavitation device 700 is illustrated. The ultrasonic cavitation device 700 can be coupled to an outlet conduit 105 or another location in a piping assembly. The ultrasonic cavitation device 700 can form a separate chamber within the outlet conduit 105. The ultrasonic cavitation device 700 may include an inlet 741 and an outlet 742. Although not shown, one or more transducers may be coupled to one side of the outlet conduit 105. Additional, different, or fewer components may be included.

[0276] The transducer can be an ultrasonic transducer that generates high-energy waves in water. The waves can be in a predetermined frequency range greater than the range of human hearing. Example frequencies include the range of 20 kHz to 60 kHz. Specific frequencies or other frequency ranges can be selected for a particular implementation. High-energy waves cause compression and expansion at the molecular level, leading to the generation of bubbles. As more energy is applied to the bubbles, the ultrasonic cavitation device 700 can cause the bubbles to implode or rupture, releasing energy. The energy can be applied to any component of the nearby water, such as bacteria, biofilms, or other microorganisms. The energy can cause microorganisms to break down into inert particles and / or further into extracellular polymeric matter. The energy can cause localized temperature spikes in the water.

[0277] The number of transducers that can be connected to the discharge pipe 105 or the piping system can vary. Transducers can be arranged at a specific height around the tank. A circular tank can have a set number of transducers around its radius. Square, rectangular, or other polygonal tanks can include transducers on each face. Transducers can be positioned at different heights.

[0278] The controller 400 can supply power to the transducer via cable 748. The controller 400 can be configured to turn the transducer on and off according to a set mode. The controller 400 may be able to select the frequency of the transducer. The controller 400 can receive user selections for the duty cycle or frequency of the transducer. An example duty cycle sufficient to convert high-bacterial water into water suitable for non-potable purposes could be 30 to 60 minutes.

[0279] Alternatively or concurrently, the transducer assembly 746, including transducer 744, may be suspended in the middle or substantially in the middle of the discharge duct 105. The transducer assembly 746 may be attached to one or more tethers 747. Tethers 747 may include cables, ropes, or other extension members attached to the wall of the tank by adhesive or fasteners. At least one of the tethers 747 may include a cable 748 for supplying power and / or control signals to the transducer assembly 746. The transducer assembly 746 may include any number of transducers 744 pointing to different portions of the tank 743.

[0280] Figure 22 An example dielectric barrier discharge device with a planar shape 800 is illustrated. Figure 23 An exemplary dielectric barrier discharge device having a cylindrical shape 810 is illustrated. The dielectric barrier discharge device includes a power supply device 801, a high-voltage electrode 802, a ground electrode 803, and a dielectric barrier 804 located between the high-voltage electrode 802 and the ground electrode 803. A discharge gap 805 is located between the ground electrode 803 and the dielectric barrier 804 and the high-voltage electrode 802. Additional, different, or fewer components may be included.

[0281] exist Figure 22 In this design, the ground electrode 803, high-voltage electrode 802, and dielectric barrier 804 are parallel plates. The plates can be planar and square or rectangular in shape. The thickness of electrodes 803 and 802 can be less than 1 mm. The thickness of the discharge gap 805 can be 2 to 5 mm. The thickness of the dielectric barrier 804 can be approximately 1 mm. The high-voltage electrode 802 can be thicker than the ground electrode 803. Therefore, in this example, the thickness of the discharge gap 805 can be greater than the thickness of the dielectric barrier 804, the thickness of the dielectric barrier 804 can be greater than the thickness of the high-voltage electrode 802, and the thickness of the high-voltage electrode 802 can be greater than the thickness of the ground electrode 803.

[0282] exist Figure 23 In this design, the ground electrode 803, the high-voltage electrode 802, and the dielectric barrier 804 are coaxial. That is, the centers of each of the ground electrode 803, the high-voltage electrode 802, and the dielectric barrier 804 are on the same line, or these centers are very close to each other. In some examples, the ground electrode 803, the high-voltage electrode 802, and the dielectric barrier 804 are each formed in a cylindrical shape.

[0283] The dielectric barrier discharge device generates a discharge between electrodes 802 and 803. This discharge can produce ozone. In many examples, a power supply device 801 provides AC current to the dielectric barrier discharge device. The AC current can range from low frequencies (10Hz to 1000Hz) to high frequencies (microwaves). High frequencies can be modulated on a carrier frequency. When the power supply device 801 is turned on, charge accumulates on electrode 802 and eventually discharges through the dielectric barrier 804 and air gap 805 to the ground electrode 803.

[0284] Example materials for the high-voltage electrode 802 may be conductive materials, such as steel, copper, silver, brass, platinum, graphite, or gold. Example materials for the grounding electrode 803 include any of these materials and may be arranged in a braid, sheet, grid, or other form. Example materials for the dielectric barrier 804 include mica, ceramic, glass, enamel, or another material.

[0285] The power supply device 801 is configured to provide a potential across the high-voltage electrode 802 and the ground electrode 803 via a dielectric barrier 804 to generate plasma from water. The plasma reduces biofilm in the piping system. The plasma can be nonthermal or cold plasma, having a relatively low temperature relative to the heavy matter (ions and neutral matter) present.

[0286] Figure 24The diagram illustrates a flowchart of the controller 400 of a biofilm prevention system. The actions in the flowchart can be performed by any combination of the control system 400, network devices, or servers. One or more actions may be performed by appliances. Additional, different, or fewer actions may be included.

[0287] In action S201, controller 400 applies an AC signal to high-voltage electrode 802. Controller 400 may operate a relay or another switch to enable power supply device 801. In some cases, a user may press a button connected to a biofilm prevention system, thereby enabling controller 400 to operate power supply device 801. In some examples, controller 400 may be wirelessly and / or via the Internet connected to an external device such as a laptop computer, tablet computer, or telephone. Controller 400 may be connected to a digital assistant that provides commands to controller 400 wirelessly or otherwise.

[0288] The controller 400 can be configured to turn on the power supply device 801 for the biofilm prevention system at specific times or on a schedule. For example, the biofilm prevention system may be turned on at night (e.g., once between 2 a.m. and 5 a.m. or intermittently). The biofilm prevention system may be turned on on certain dates or according to a schedule specified by the user and external devices. According to any of the embodiments described herein, the biofilm prevention system may be turned on in response to sensor data. For example, sensor data may include the flow rate of the piping device, or the total flow rate of the piping device since the last operation of the biofilm prevention system. Sensor data may include data indicating the state of the piping device (e.g., the number of microorganisms present in the piping device or the turbidity of the water in the piping device).

[0289] The controller 400 can be configured to deactivate the biofilm prevention system in the event of an error or malfunction. In some examples, a separate emergency switch can be connected to the high-voltage electrode 802, allowing the user to immediately disable the biofilm prevention system. In other examples, the controller 400 can monitor sensors or voltage levels in the circuit to determine if an error has occurred. In response, the controller 400 can generate a fault signal that effectively grounds the high-voltage electrode 802 and shuts down the biofilm prevention system.

[0290] In action S203, the operation of the power supply device 801 by the controller 400 causes a discharge between the high-voltage electrode 802 and the ground electrode 803. After the charge on the high-voltage electrode 802 accumulates to a level sufficient to allow current to jump across the gap 805, the current flows to the ground electrode 803. During this process, plasma is discharged in action S205. The plasma may include ozone.

[0291] In action S207, controller 400 may supply plasma to the piping system to reduce biofilm in the piping system. Controller 400 may open a valve to release ozone into the piping system. In other examples, ozone may be continuously supplied when biofilm prevention devices are provided in series in the piping system, or when ozone is generated by power supply device 801.
