[0032] Reference Figs. 1 to 4 In one embodiment of this utility model, a cleaning-type automatic faucet includes:
[0033] Support tube 100;
[0034] A liquid outlet head 200 is connected to the upper part of the support tube 100 and extends away from the support tube 100 in a plane. A first proximity sensor 110 is provided on the support tube 100 below the output end of the liquid outlet head 200.
[0035] The end of the liquid guide tube 300 is connected to the inner end of the liquid outlet head 200, while the starting end corresponds to the outer material tank 010.
[0036] A liquid delivery drive is provided corresponding to the material tank 010 and is used to drive the hand sanitizer in the material tank 010 out.
[0037] A water outlet head 400 is connected to the middle of the height of the support pipe 100. The water outlet head 400 includes a main body 410 and a hollow part 420 disposed in the main body 410. A flow channel is disposed in the main body 410. At least one water outlet hole 411 is disposed on the main body 410 and leads to the flow channel. The flow channel leads to the support pipe 100. The vertical projection of the output end of the liquid outlet head 200 falls into the hollow part 420. A second proximity sensor 120 is disposed on the support pipe 100 below the output end of the water outlet head 400.
[0038] A water inlet pipe 500 passes through the bottom of the support pipe 100 and is connected to the flow channel. A first electrically controlled on / off switch 510 is provided on the water inlet pipe 500.
[0039] The controller is electrically connected to the first proximity sensor 110, the second proximity sensor 120, the liquid delivery drive, and the first electrically controlled on / off switch 510. The controller receives signals sent by the first proximity sensor 110 and the second proximity sensor 120, and controls the operation of the liquid delivery drive and the first electrically controlled on / off switch 510.
[0040] In existing technologies, adding a hand sanitizer dispenser to a faucet not only affects the appearance, but also causes uncollected hand sanitizer to drip onto the sink, resulting in contamination and reducing the aesthetic appeal, especially in public places where it is frequently used.
[0041] The cleaning-type automatic faucet provided by this utility model includes:
[0042] The support pipe 100 serves as the main structure. The support pipe 100 is the entry point for the water inlet pipe 500 or the liquid guide pipe 300.
[0043] The liquid outlet 200 is connected to the upper part of the support tube 100 and extends away from the support tube 100 in a plane. The liquid outlet 200 is not limited to being connected into the support tube 100, but can also be fixed by the support tube 100, thereby facilitating the subsequent installation of the liquid guide tube 300 and the material tank 010. A first proximity sensor 110 is provided on the support tube 100 below the output end of the liquid outlet 200, and the operation of the first proximity sensor 110 generates a working signal.
[0044] The end of the liquid guide tube 300 connects to the inner end of the liquid outlet 200. The starting end of the liquid guide tube 300 corresponds to the external container 010. The container 010 is the storage location for the hand sanitizer. The liquid guide tube 300 is the channel for the hand sanitizer to pass through.
[0045] The liquid delivery drive is configured to drive the hand sanitizer in the container 010. The type of liquid delivery drive can be varied, such as drawing hand sanitizer from the container 010, or having a piston-type structure for the container 010 to squeeze out the hand sanitizer from the container 010.
[0046] A water outlet 400 is connected to the middle of the height of the support pipe 100. The water outlet 400 includes a hollow portion 410. The water outlet 400 includes a main body 410 and a hollow portion 420 disposed within the main body 410. A flow channel is provided within the main body 410, and at least one water outlet hole 411 is provided on the main body 410, leading to the flow channel. Water is dispensed through the water outlet hole 411. The vertical projection of the output end of the liquid outlet 200 falls into the hollow portion 410, allowing any uncollected hand sanitizer to drip through the hollow portion 410 and fall into the sink, preventing hand sanitizer from dripping outside the sink. A second proximity sensor 120 is disposed on the support pipe 100 below the output end of the water outlet 400, generating a working signal upon operation. The first proximity sensor 110 and the second proximity sensor 120 can be infrared or ultrasonic, and there is no specific limitation, as long as they can detect the approach action.
[0047] The water inlet pipe 500 passes through the bottom of the support pipe 100 and leads to the hollow part 410. A first electrically controlled on / off switch 510 is provided on the water inlet pipe 500.
[0048] The controller is electrically connected to the first proximity sensor 110, the second proximity sensor 120, the liquid delivery drive, and the first electrically controlled on / off switch 510. The controller receives signals from the first proximity sensor 110 and the second proximity sensor 120, and controls the operation of the liquid delivery drive and the first electrically controlled on / off switch 510. The controller, the first proximity sensor 110, the second proximity sensor 120, the liquid delivery drive, and the first electrically controlled on / off switch 510 can be powered by an external AC power source or have a built-in power bank.
[0049] During the work process:
[0050] When a hand is placed at the position of the first proximity sensor 110, the controller receives the activation signal from the first proximity sensor 110 and activates the liquid dispensing drive, dispensing hand sanitizer. When the first proximity sensor 110 is no longer activated, the controller stops the liquid dispensing drive, and the hand sanitizer dispensing stops.
[0051] When a hand is placed at the location of the second proximity sensor 120, the controller receives the signal indicating that the second proximity sensor 120 is activated. The controller then controls the first electrically controlled on / off switch 510 to be on, allowing water to flow out from the water outlet 400. When the second proximity sensor 120 is no longer activated, the controller controls the first electrically controlled on / off switch 510 to be off, and water no longer flows out from the water outlet 400.
[0052] In summary, the liquid outlet 200 is connected to the upper part of the support tube 100; the water outlet 400 is connected to the middle part of the support tube 100, and the water outlet 400 is provided with a hollow part 410; a first proximity sensor 110 is provided on the support tube 100 below the output end of the liquid outlet 200, and a second proximity sensor 120 is provided on the support tube 100 below the output end of the water outlet 400; the vertical projection of the output end of the liquid outlet 200 falls into the hollow part 410, so the hand sanitizer dripped from the liquid outlet 200 but not caught can pass through the hollow part 410 and drip into the sink, avoiding the situation where the hand sanitizer drips outside the sink.
[0053] In one embodiment, the liquid delivery drive is a motor-driven linear drive, the material tank 010 is a piston type, and the liquid delivery drive drives the material tank 010 to squeeze out the hand sanitizer inside the material tank 010.
[0054] In this embodiment, the feed container 010 has a syringe-like structure, allowing the hand sanitizer it contains to be extruded. The extrusion process is achieved via a motor-driven linear actuator, offering the advantage of stable output.
[0055] In one embodiment, the liquid delivery drive is a micro water pump, and the liquid delivery drive is connected to the starting end of the liquid guide tube 300.
[0056] In this embodiment, a liquid delivery drive (submersible pump) draws hand sanitizer from the tank 010 and pumps it into the liquid delivery pipe 300, thereby completing the delivery of the hand sanitizer. The above pumping process has the advantages of simple structure and easy maintenance.
[0057] Reference Figs. 1 to 2 In one embodiment, the main body 410 is block-shaped, and the flow channel is disposed in the middle of the thickness direction of the main body 410.
[0058] In this embodiment, the block-shaped main body 410 is relatively simple to process and has high structural strength. The flow channel can be integrally formed or formed through post-processing. Water in the inlet pipe 500 enters the main body 410 through the flow channel.
[0059] Reference Figs. 3 to 4 In one embodiment, the main body 410 includes a tubular portion 412 and an annular portion 413 connected to each other, the middle part of the annular portion 413 is the hollow portion 420, and the interior of the tubular portion 412 and the annular portion 413 is the flow channel.
[0060] In this embodiment, the annular portion 413 is connected to the support tube 100 through the tubular portion 412, thereby reducing the size of the annular portion 413 to a certain extent, which facilitates use and reduces material consumption.
[0061] Reference Figs. 3 to 4 In one embodiment, the water outlet 411 extends circumferentially along the annular portion 413 and is annular in shape.
[0062] In this embodiment, the shape of the water outlet 411 is restricted to an annular shape, thereby making the water outlet process smoother.
[0063] Reference Figs. 1 to 2 In one embodiment, the liquid outlet 200 is connected to the support tube 100, and the liquid guide tube 300 passes through the lower end of the support tube 100 and is connected to the liquid outlet 200.
[0064] In this embodiment, the extension of the liquid guide tube 300 is located inside the support tube 100, and the material bucket 010 can be located below the water tank. This results in a simple overall shape, and the structure at the support tube 100 location is also simpler and easier to maintain.
[0065] In one embodiment, the first proximity sensor 110 and the second proximity sensor 120 are infrared sensors.
[0066] In this embodiment, the first proximity sensor 110 and the second proximity sensor 120 are limited to infrared sensors, which has the advantages of maturity and reliability. Taking the first proximity sensor 110 as an example, it includes an infrared emitter (such as an IRLED) and a receiver (such as a TSOP1738). When a hand approaches, the reflected infrared light is captured by the receiver, triggering the control circuit. The receiver outputs a low-level signal (when reflected light is detected), which generates a drive command through a microcontroller (such as an Arduino) or a timer circuit.
[0067] In one embodiment, a second electrically controlled on / off switch is provided on the liquid guide tube 300.
[0068] In this embodiment, a second electrically controlled on / off switch is added, thus providing a basis for accurate delivery of hand sanitizer. During operation, not only is the output of hand sanitizer paused by stopping the liquid delivery drive, but the second electrically controlled on / off switch also shuts off the operation of the liquid delivery tube 300, thereby preventing hand sanitizer leakage.
[0069] In one embodiment, the first electrically controlled on switch 510 and the second electrically controlled on switch are solenoid valve type switches.
[0070] In this embodiment, both the first and second electrically controlled on / off switches are limited to solenoid valve type switches, which have the advantages of simple structure and stable performance. A solenoid valve uses the magnetic field generated by an electromagnetic coil to drive the valve core to move, thereby realizing the on / off or flow direction switching of fluid. It typically consists of two parts: an electromagnetic coil, responsible for generating electromagnetic force; and a valve body, including components such as the valve core and valve seat, used to control the fluid passage. When the electromagnetic coil is energized, the coil generates a magnetic field that attracts the valve core to move, thereby opening or closing the valve. When the electromagnetic coil is de-energized, a spring or other reset device pushes the valve core back to its original position, restoring the default state.
[0071] In summary, the cleaning-type automatic faucet provided by this utility model has a liquid outlet 200 connected to the upper part of the support tube 100; a water outlet 400 connected to the middle part of the support tube 100, and a hollow part 410 provided on the water outlet 400; a first proximity sensor 110 and a second proximity sensor 120 are provided on the support tube 100 corresponding to the lower part of the output end of the liquid outlet 200; the vertical projection of the output end of the liquid outlet 200 falls into the hollow part 410, so the hand sanitizer dripping from the liquid outlet 200 that is not caught can pass through the hollow part 410 and drip into the sink, avoiding the situation where the hand sanitizer drips outside the sink.
[0072] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
