Description

AN APPAR TUS FOR FLUID DELIVERY

[0001] The invention relates to the technical field cleaning. In particular, an apparatus for fluid delivery, which further has power delivery.BACKGROUND OF THE INVENTION

[0002] Technological advancements in robotics have caused robots to have an increased use in daily human activities. In particular, one area of interest relates to robots that perform cleaning activities on facilities, amenities, buildings, or the like, i.e. cleaning robots. These robots are configured to have both electrical motors and sensors, and at the same time have means to deliver and discharge fluid for them to perform cleaning activities. Since most fluids are conductors of electricity, careful consideration is required for these robots to operate accordingly with minimal fluid exposure.

[0003] Conventionally, these robots may have interchangeable end effector designs that use pogo pins and / or gold-plated copper contacts to pass current from the robot to the various end effectors to turn on motors or valves or to collect signals from sensors. The disadvantage of such designs is that when the applicable environment is moist or has splashing fluids, such open electrical contacts will result in short circuits, system breakdown and component damage. Hence, this shall pose a safety hazard to its surroundings.

[0004] There are a few disclosed technologies over the prior art relating to an apparatus for fluid delivery, together with a system and method thereof. Among them include the China Patent Application CN219048256, which discloses a cleaning robot with a tank body that comprises a cleaning mechanism, a multi-axis mechanical arm, a travelling mechanism, and a controller. The cleaning mechanism comprises a mop head for cleaning the ground, a cleaning head for spraying cleaning liquid, a blowing head for blowing, and a mechanical claw. In particular, the mechanical arm is connectable with any one or a combination of the cleaning mechanism, mop head, cleaning head, blowing head, and mechanical claw, for performing its tasks.

The apparatus is enabled to provide remote power transfer via phenomena such as electromagnetic induction to minimise contact between (i) wiring within the apparatus, and (ii) the fluid travelling within the apparatus.

[0050] It is to be noted that, in the context of the present application, the term “fluid” may refer to matter that is in a liquid state, a gaseous state, a liquid-gaseous state, or any other state which enables the said matter to exhibit flow properties. By way of example, the fluidmay be, but shall not be limited to super-heated steam, water, air, cleaning detergent, sanitisers, corrosive fluids such as bleach, or mixtures thereof.

[0051] The invention will now be described in greater detail, by way of example, with reference to the figures. For ease of reference, common reference numerals or series of numerals will be used throughout the figures when referring to the same or similar features common to the figures.

[0052] FIG. 1 illustrates a simplified schematic diagram of the apparatus of the present invention whereby its pieces are detached. Whereas, FIG.2 illustrates a simplified schematic diagram of the apparatus of the present invention whereby its pieces are joined together.

[0053] As shown in FIGS 1 and 2, the apparatus of the present invention may comprise a first piece 100 and a second piece 200, with the second piece 200 capable of being detachably joined to the first piece 100.

The third set of wiring 321 may deliver power from the power receiving unit 204 to the second control unit 205. Whereas, the fourth set of wiring 322 may deliver power from the second control unit 205 to the actuator 206, the sensing unit 207, the communication unit 208, or a combination thereof.

[0058] It is to be noted that the fourth set of wiring 322 may further comprise one or more sub-sets of wiring, which shall include a first subset of wiring between the second control unit 205 and the actuator 206, a second subset of wiring between the second control unit 205 and the sensing unit 207, and a third subset of wiring between the second control unit 205 and the communication unit 208.

[0059] As shown in FIGS 1 and 2, the first enclosure 101 of the first piece 100 may substantially enclose either one of the first fluid line 102 or portions thereof, the first locking member 103 or portions thereof, the first control unit 104 or portions thereof, the power transmitting unit 105 or portions thereof, the first set of wiring 311 or portions thereof, the second set of wiring or portions thereof, or a combination thereof.

[0060] As shown in FIGS 1 and 2, the second enclosure 201 of the second piece 200 may substantially enclose either one of the second fluid line 202 or portions thereof, the second locking member 203 or portions thereof, the second control unit 205 or portions thereof, the power receiving unit 204 or portions thereof, the actuator 206 or portions thereof, the sensing unit 207 or portions thereof, the communication unit 208 or portions thereof, the fluid manipulator unit 209 or portions thereof, the third set of wiring 321 or portions thereof, or the fourth set of wiring 322 or portions thereof.

[0061] As shown in FIGS 1 and 2, it is to be noted that the first locking member 103 of the first piece 100 and the second locking member 203 of the second piece 200 may each comprise a combination of components that shall enable (i) the second piece 203 to be joined to the first piece 100 wherein the first fluid line 102 is in connection with the second fluidline 202 in a hermetically sealed manner without potential fluid leakages, and (ii) the second piece 200 to be detached from the fust piece 100 for it to be interchanged with other the second pieces 200 that are of alternative configurations.

[0062] As shown in FIG. 2, as the second piece 200 is joined to the first piece 100, the first fluid line 101 and the second fluid line 102 may become in connection with each other. Furthermore, the power transmitting unit 105 may become in the vicinity of the power receiving unit 204.

[0063] As shown in FIG. 2, as the second piece 200 is joined to the first piece 100, fluid may travel through the first fluid line 102, and subsequently the second fluid line 202 to be dispensed out from the second piece 200.

[0064] As shown in FIG. 2, as the second piece 200 is joined to the first piece 100, the provision of power to any one or a combination of the actuator 206, the sensing unit 207, and the communication unit 208 may be described through a series of steps.

[0065] There may be a first step that involves delivering power, which may be in the form of direct current (DC) power, to the first control unit 104 via the first set of wiring 311. The DC power may be provided via a conventional relay or solid-state relay.

[0066] Next, there may be a second step that involves the first control unit 104 delivering power, which may be in the form of alternating current (AC) power, to the power transmitting unit 105 via the second set of wiring 312. More specifically, the first control unit 104 generates high frequency and high voltage waveforms that are provided to the power transmitting unit 105. The frequency may range from about 1 Hz - 10MHz, or more. The voltage may range from about IV - 50V, but most preferably IV - 48V.

[0067] Next, there may be a third step that involves the power transmitting unit 105 interacting with the power receiving unit 204, for a flow of electricity to be induced within the power receiving unit 204 or portions thereof. More specifically, the power receiving unit 204 picks up the high frequency and high voltage waves, which are transmitted from the power transmitting unit 105 and propagate remotely between the first piece 100 and the second piece 200 in a contactless manner. It is to be stated that the AC power that is transmitted by the power transmitting unit 105 preferably propagates through the material,which may be non-magnctic, at a distance that substantially ranges from about 0.1mm to 7mm to reach the power receiving unit 204.

[0068] Next, there may be a fourth step that involves power receiving unit 204 delivering power, which may be in the form of AC power, to the second control unit 205 via the third set of wiring 321.

[0069] Finally, there may be a fifth step that involves the second control unit 205 delivering power, which may be in the form of DC power, to any one or a combination of the actuator 206, the sensing unit 207, and the communication unit 208 via the fourth set of wiring 322. More specifically, the second control unit 205 may rectify the AC power provided to it and convert the AC power into DC power.

[0070] In particular', whilst not shown, the first control unit 104 may include a microcontroller or a single-board computer having a processor that operates one or more peripherals. Its peripherals may include an inverter module that converts the incoming DC power from the first set of wiring 311 into outgoing AC power that is provided to the second set of wiring 312.

[0071] In particular, whilst not shown, the second control unit 205 may include a microcontroller or a single-board computer having a processor that operates one or more peripherals. Its peripherals may include a rectifier module that converts the incoming AC power from the third set of wiring 312 into outgoing DC power that is provided to the fourth set of wiring 322.

[0072] In particular', the power transmitting unit 105 may have a plurality of coils housed therewithin that is capable of exhibiting a magnetic field when AC power flows therethrough. These coils may be winded to be substantially in the form of an annular plate or an annular cylinder.

[0073] In particular, the power receiving unit 204 may have a plurality of coils housed within, that is capable of having a flow of electricity to be induced within them when they receive a propagating and alternating magnetic field. These coils may be winded to be substantially in the form of an annular plate or an annular cylinder.

[0074] It is to be noted that the number of turns of the coil windings of the power transmitting unit 105, N], and the number of turns of the coil windings of the power receiving unit 204, N2, may be configured to be different or be the same. Should they be configured to be different, power transmitted from the power transmitting unit 105 to the power receiving unit 204 may step up (Ni < Ni), step down (Ni > N2), or equal (Ni = N2), accordingly.

[0075] In particular, the actuator 206 may include any one or a combination of motors, valves, pumps, or the like. The actuator 206 may operate the fluid manipulator unit 207 so that dispensation parameters of the fluid that is dispensed from the second fluid line 202 may be manipulated. By way of example, the dispensation parameter may include, but shall not be limited to, fluid pressure, fluid spraying area, or the like. The subset of wiring that is between the actuator 206 and the control unit 205 may be involved in delivering power from the control unit 205 to the actuator 206, and sending control instructions from the control unit 205 to the actuator 206.

[0076] In particular, the sensing unit 207 may comprise one or more sensors that perform sensing of the surroundings of the second piece 200 of the internals of the second piece 200. The subset of wiring that is between the sensing unit 207 and the control unit 205 may be involved in delivering power from the control unit 205 to the sensing unit 207, and sending sensing signals from the sensing unit 207 to the control unit 205.

[0077] In particular, the communication unit 208 enables the second piece 200 to communicate with one or more communication receivers that may be in the vicinity of the apparatus. The communication unit 208 may be configured to perform wireless or remote communication via Bluetooth, Wifi, or any other communication configurations that may fall under IEEE 802 standards. The subset of wiring that is between the communication unit 208 and the control unit 205 may be involved in delivering power from the control unit 205 to the communication unit 208, enabling communication signals received by communication unit 208 to be provided to the control unit 205, and enabling communication signals to be provided from the control unit 205 to the communication unit 208 for these signals to be broadcasted for communicating with the communication receivers.L0078J With this, the actuator 206, the sensing unit 207, and the communication unit 208, may interact within the second piece 200 while being isolated from the first piece 100. The second control unit 205 may facilitate their interactions while delivering power to them. In one example, the sensing unit 207 and / or the communication unit 208 may provide information to the second control unit 205. With this, the second control unit 205 may provide control instructions to the actuator 206 for it to operate accordingly.

[0079] Whilst not shown, the second piece 200 may further comprise a power storage unit that may similarly have a subset of wiring that is connected to the second control unit 205. The power storage unit may be in the form of a battery or a high-capacitance capacitor (supercapacitors, ultracapacitors, etc.), or the like. The set of wiring between the power storage unit and the second control unit 205 may be involved in delivering DC power from the second control unit 205 to the power storage unit, or vice versa. With this, the power storage unit may provide an extra power boost during high current demands.

[0080] Preferably, during the provision of power to any one or a combination of the actuator 206, the sensing unit 207, the communication unit 208 and the power storage unit (if present), fluid flows through the first fluid line 102 and the second fluid line 202.

[0081] Whilst not shown, one or more isolation means may be included within each piece 100, 200 of the apparatus. In one example, the isolation means may be in the form of water- resistant barriers, encapsulants that are made from thermo-conductive and / or electrically- insulating materials (e.g. epoxy, silicon, etc.), or the like. The isolation means may also be in the form of hydrophobic materials. The isolation means may encapsulate any one or a combination of components in which power travels therethrough, which shall include the first control unit 104 or portions thereof, the power transmitting unit 105 or portions thereof, the first set of wiring 311 or portions thereof, the second set of wiring or portions thereof, the second control unit 205 or portions thereof, the power receiving unit 204 or portions thereof, the actuator 206 or portions thereof, the sensing unit 207 or portions thereof, the communications unit 208 or portions thereof, the power storage unit or portions thereof (if present), the third set of wiring 321 or portions thereof, and the fourth set of wiring 322 or portions thereof. With this, power and signal transmission within the pieces 100, 200 shall be reliable and robust. Furthermore, as the electrical components of both pieces 100, 200 are preferably encapsulated or scaled within thermo-conductive and / or clcctrically-insulatingmaterials (c.g. epoxy), electrical short circuits arc avoided as there arc no electrical components that are in contact with any of the fluid.

[0084] As shown in the embodiment of FIGS 3 and 4, it is to be noted that the first fluid line 102 of the first piece 100 may have one or more inlets 1021. Each of these inlets may further have the valve 4 that controls the flow of fluid into the respective inlet 102. Preferably, the valve 4 is a check valve, but it may be any other suitable valve. The first fluid line 102 of the fust piece 100 may further have a common cavity 1022 that is formed by the internal walls of the first piece 100, with fluid flowable between the common cavity 1022 and each respective inlet 1021. This design shall allow fluid such as super-heated steam, water, compressed air, vacuum and other fluids like cleaning detergent, sanitizing mist, bleach, etc., to pass through the cavity 1022 while power is being transmitted without any risk of the fluid interacting with the electrical components.

[0085] As shown in the embodiment of FIGS 3 and 4, it is to be noted that the second fluid line 202 of the second piece 200 may comprise a conduit 2021 therewithin in which fluid travels therethrough. The conduit 2021 may substantially protrude from the second piece 200. Whilst not shown, the second fluid line 202 may further comprise a nozzle that allows fluid to be dispensed from second piece 200.

[0086] As shown in the embodiment of FIGS 3 and 4, the first locking member 103 may comprise multiple components that include a first pin 1031. a bush member 1032, a second pin 1033, and one or more seals 1034.

[0087] In particular, the first pin 1031 is preferably in the form of a locking pin that serves to enable the first piece 100 to be locked to the second piece 200.

[0088] In particular, the bush member 1032 is preferably in the form of a magnetic bush wherein the first pin 1032 or portions thereof are sleeved therein. The bush member 1032 further serves to hold the locking pin 1032 in a fixed position.

[0089] In particular, the second pin 1033 is a positioning pin that serves to ensure that the second piece 200 is joined to the first piece 100 at a predetermined position wherein the first pin 1031 may be received by the second piece 200.

[0090] In particular, the seals 1034 are disposed along the walls of the cavity 1022. Preferably, the seals 1034 are in the form of O-rings, or the like.
