Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of faucet water outlet intelligent control. More specifically, the present application relates to an intelligent double-control faucet and a control method thereof. BACKGROUND

[0002] In the field of modern smart home and public health facilities, inductive control faucets have received widespread attention and application due to their convenience and hygiene. Such faucets usually combine traditional mechanical operation with advanced induction technology, aiming to provide a more intelligent and user-friendly user experience. However, the inductive control faucets widely used in the market still have some technical limitations and user experience deficiencies in design, which are specifically manifested in the following aspects:

[0003] First, the linkage problem of mechanical handle and induction control

[0004] Existing inductive control faucets generally adopt a "dual-mode" operation design, i.e., the user first needs to manually open the mechanical handle to put the faucet into standby state, and then can turn on the faucet water outlet through induction (such as infrared induction). The original intention of this design is to introduce the convenience of induction control while maintaining the traditional operation habit. However, in actual use, due to the deep-rooted habit of users using mechanical handle to directly control water flow, many users often directly turn off the faucet water outlet by operating the mechanical handle after use, rather than using the induction function to turn off. This behavior causes the induction system inside the faucet to fail to correctly record the off state, so that the faucet cannot normally water when trying to operate through induction next time. This "misoperation trap" in design not only affects the user experience, but also limits the effective application of induction control technology.

[0005] Second, high cost of control box and battery endurance problem

[0006] In advanced inductive control faucets that adjust water temperature and water volume, a complex control box system is usually equipped. These control boxes have multiple drive motors integrated inside, which are used to accurately control the opening degree of the valve, the power of the heating element, etc., to achieve fine adjustment of water temperature and water flow. Although this design provides high personalization and comfort, it significantly increases hardware costs. The use of multiple drive motors not only increases manufacturing costs, but also increases the complexity of later maintenance. In addition, since the control box needs to be powered to operate, and most inductive faucets use batteries as energy supply to maintain the simplicity and portability of the design. However, the energy consumption demand of multiple drive motors leads to fast battery consumption, and frequent battery replacement not only brings inconvenience to users, but also increases long-term use costs, especially in public places, this problem is particularly prominent.

DETAILED DESCRIPTION

[0041] The present application will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement the present application according to the description in the specification.

[0042] In the description of the present application, the term "indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0043] As Figures 1-9 shown, the present application provides a smart double-control faucet, which has a whole structure including a faucet body 1, a valve body 5, a water body transmission structure 6, a controller 7 and other auxiliary components, and the following is a detailed description of each part:

[0044] The faucet body 1 is the main part of the intelligent double control faucet, which is provided with a mechanical handle 2, a water outlet pipe 3 and a sensor 4. The mechanical handle 2 is connected with the water path switching structure in the valve body 5 through a mechanical linkage mechanism, and the user can select one of the two water outlets 51 for water control by operating the mechanical handle 2. The water outlet pipe 3 is used to discharge the water treated by the valve body 5 and the water body transmission structure 6. The sensor 4 is used to detect the user's operation and generate signals to send to the controller 7. The sensor 4 is used to detect the user's operation and generate signals to send to the controller 7, which may include the user's touch, proximity or movement. Specifically, the sensor 4 is selected from an infrared sensor, a touch sensor or a proximity sensor. In this embodiment, the sensor 4 is an infrared sensor, and is arranged on the side of the faucet body 1 opposite to the mechanical handle 2, so as to ensure that the user can conveniently control the faucet through the sensing operation.

[0045] The valve body 5 has two water outlets 51, wherein the mechanical handle 2 is connected with the water path switching structure in the valve body 5 through a mechanical linkage mechanism to realize the selective water control of the two water outlets 51. Specifically, the mechanical handle 2 is connected with the valve rod 52 of the valve core 54, and drives the valve rod 52 to swing to select the water outlet 51. Preferably, the valve body 5 has two water inlets 53 corresponding to two different water inlet modes (such as cold water and hot water), and the mechanical handle 2 drives the valve rod 52 to rotate to adjust the water inlet ratio and water inlet amount of the two water inlets 53, so as to adjust the water outlet temperature of the water outlet 51.

[0046] The water body transmission structure 6 includes two independent water inlet channels 61 and two electromagnetic valves 62. The two water inlet channels 61 are respectively and independently connected with the two water outlets 51, and each water inlet channel 61 is provided with an electromagnetic valve 62 as a control element. The two water inlet channels 61 are connected with a single water outlet channel 63 in common, and the water outlet channel 63 is connected with the water outlet pipe 3. Each electromagnetic valve 62 respectively controls the communication state between the water inlet channel 61 and the water outlet channel 63, thereby realizing the control of the water outlet. Each water inlet channel 61 is provided with a water flow detector 64, and each water flow detector 64 respectively detects whether there is water flow in the water inlet channel 61. Specifically, the water flow detector 64 is a Hall water flow sensor.

[0047] A controller 7 is configured to have a state memory module that can record and store the opening and closing states of the two solenoid valves 62 before the induction operation occurs and the last detection result of the water flow detector 64; wherein when the inductor 4 detects a preset trigger condition and sends a signal to the controller 7, the controller 7 will select and send a control instruction opposite to the last induction control instruction to the corresponding solenoid valve 62 according to the solenoid valve 62 state information (open / close) stored in its internal memory before receiving the current signal. The controller 7 is the core component of the intelligent double-control faucet, responsible for receiving signals from the inductor 4 and sending control instructions. Specifically, when the user's hand approaches the inductor 4, the inductor 4 detects the trigger condition and sends a signal to the controller 7. Specifically, the state memory module is selected as the internal memory of the controller 7. When the controller 7 needs to perform an operation (such as water output), it will first backtrack to the opening and closing states of the two solenoid valves 62 before the induction operation, which is achieved by querying the state records stored in the internal memory. According to the backtracked state information and the user's instruction (signal sent by the inductor 4), the controller 7 will generate corresponding control signals and send them to the solenoid valve 62 through a circuit or interface. These control signals will change the coil current, voltage or magnetic field of the solenoid valve 62, thereby controlling the opening and closing of the solenoid valve 62.

[0048] In the above technical solution, the controller 7 monitors and records the state of the solenoid valve 62 in real time, receives and processes signals from the inductor 4, backtracks state information and executes instructions, and sets up a feedback mechanism to record the opening and closing states of the two solenoid valves 62 before the induction operation and the water flow passing state. These steps and technical elements together ensure the accuracy and reliability of the intelligent control faucet, as well as the intelligent control of the induction or mechanical handle 2, which can achieve the user's operation intention and turn on or off the faucet.

[0049] Auxiliary components of the intelligent double-control faucet:

[0050] A battery box assembly 8 is installed inside a set of battery cells, which provides power for the controller 7, inductor 4, water flow detector 64 and solenoid valve 62. The battery box assembly 8 can be easily disassembled and replaced with batteries to ensure the continuous operation of the intelligent double-control faucet. Since the control box 10 does not need to be equipped with a large number of driving motors, only the control elements need to be powered, the power consumption is slow, and the battery does not need to be replaced frequently.

[0051] Water outlet pipe 3 and telescopic water outlet nozzle 9, water outlet pipe 3 is a flexible pipe that can easily adjust the water outlet direction and position. The telescopic water outlet nozzle 9 is connected to the water outlet pipe 3, and the user can adjust the length and angle of the water outlet nozzle according to needs.

[0052] Filtering components are arranged at the water inlet ends of the water inlet channels 61. The filtering components are used to remove impurities, particulate matters and the like from the water to ensure the cleanliness of the water and the safety of the water usage. In particular, the filtering components are selected from filter screens 112.

[0053] The control box 10 is a closed housing 101 in which the water body transmission structure 6 and the controller 7 are integrated. In this embodiment, the housing 101 is internally integrated with the water body transmission structure 6 and the controller 7, wherein the two water inlet channels 61 are symmetrically and spacedly arranged, and the controller 7 and the water outlet channel 63 are arranged in the space between the two water inlet channels 61. The symmetric arrangement helps to ensure the uniform distribution of the water flow, reduce vortex and turbulent flow, and improve the stability of the water outlet. Through the integrated arrangement, the overall structure is compact and durable, so that the control box 10 can work stably in various environments, and is convenient to carry and store.

[0054] The housing 101 is sealed and provided with at least three threaded pipe openings 102, which are respectively in sealed communication with the water inlet ends of the two water inlet channels 61 and the outlet end of the water outlet channel 63.

[0055] A plurality of quick connection adapters 103 are provided, one end of each of the quick connection adapters 103 is a threaded end 104, and the other end is a buckle end 105. The threaded end 104 is in sealed threaded connection with the threaded pipe opening 102.

[0056] Two connecting pipes 106 are provided, one end of each of the connecting pipes 106 is in sealed communication with the two water outlets 51, and the other end is provided with a buckle joint 107 and is in sealed communication connection with the buckle end 105 of the quick connection adapter 103 on the water inlet channel 61. The water inlet end of the water outlet pipe 3 is also provided with a buckle joint 107 and is in sealed communication connection with the buckle end 105 of the quick connection adapter 103 on the water outlet channel 63.

[0057] The housing 101 is sealed and provided with at least three threaded pipe openings 102, which are respectively in sealed communication with the water inlet ends of the two water inlet channels 61 and the outlet end of the water outlet channel 63. In this embodiment, there are three threaded pipe openings 102. Two quick connection adapters 103 are used to connect the threaded pipe openings 102 and the connecting pipes 106, to realize quick and reliable connection. One end of each of the two connecting pipes 106 is in sealed communication with the two water outlets 51, and the other end is connected with the water inlet channel 61 through the quick connection adapter 103. The water inlet end of the water outlet pipe 3 is also connected with the water outlet channel 63 through a quick connection adapter 103.

[0058] In the above technical solution, the control box 10 realizes the functions of multi-source water inlet and unified water outlet by designing two water inlet quick connector interfaces and one water outlet quick connector interface. Through the setting of the quick adapter and the buckle connector 107 and the threaded pipe opening 102, the pipeline can be quickly and firmly connected, and the pipeline can also be easily disassembled and maintained, thereby improving the convenience and practicality.

[0059] In another technical solution, the controller 7 is configured to have a timing module for monitoring the time for which the feedback signal of the water flow detector 64 is continuously received from the time when the feedback signal is received by the controller 7, and if the time exceeds a set threshold, the operation of closing the electromagnetic valve 62 is performed.

[0060] In the above technical solution, some places that need frequent water but may cause water resource waste due to forgetting to close the faucet, such as in daily activities such as dish washing, vegetable washing, and hand washing, the user may forget to close the faucet due to being busy with other things, resulting in unnecessary waste of water resources. When the time of water flow (such as the water flow time exceeding 3 minutes) exceeds a set threshold, the faucet flow is automatically closed, the faucet is automatically closed when not used for a long time, and the waste of water resources is avoided.

[0061] Based on the structure of the above-mentioned intelligent double-control faucet, the application also provides a control method of the intelligent double-control faucet. The method comprises the following steps:

[0062] When the inductor 4 detects a preset trigger condition and sends a signal to the controller 7, the controller 7 will select and send a control instruction opposite to the last valid inductive control instruction to the corresponding electromagnetic valve 62 according to the electromagnetic valve 62 state information corresponding to the last valid inductive control instruction stored in the controller 7 before receiving the current signal.

[0063] In the above technical solution, when the inductor 4 detects a preset trigger condition (such as the user's hand approaching the inductor 4) and sends a signal to the controller 7, the controller 7 starts to work.

[0064] The controller 7 selects and sends a control instruction opposite to the last valid inductive control instruction to the corresponding electromagnetic valve 62 according to the electromagnetic valve 62 state information corresponding to the last valid inductive control instruction stored in the controller 7 before receiving the current signal. For example, if the valid inductive control instruction is to open the electromagnetic valve I and close the electromagnetic valve II, this time the inductive operation will close the electromagnetic valve I and open the electromagnetic valve II.

[0065] The controller 7 monitors the time from sending the control command to receiving the feedback signal. If the feedback signal is not received within the set threshold time (in this embodiment, the threshold is set to milliseconds), the control command is invalid. For example, the water flow signal is sent by the Hall water flow sensor when water flows through the water inlet channel I (the water inlet channel I corresponds to the electromagnetic valve I, and the electromagnetic valve 62 is switched from closed to open). The corresponding water flow detector 64 generates a feedback signal indicating the presence of water flow. The controller 7 determines that the control command is completed and is an effective control command.

[0066] In this embodiment, specifically, the two water inlets 53 (water inlet I and water inlet II) and the two water outlets 51 (water outlet I and water outlet II) of the valve body 5 are connected to the hot water source and the cold water source, respectively, and enter the mixed water chamber in the valve body 5 through the cold water channel 108 and the hot water channel 109. The water outlet I and the water outlet II are selectively connected to the mixed water chamber (mixed hot water and cold water) in the valve body 5 through the mixed water channel I 110 and the mixed water channel II 111, respectively. The position I and the position II of the mechanical handle 2 correspond to two swing angles of the valve rod 52, respectively, and correspond to the communication state of the water outlet I and the water outlet II with the mixed water chamber. The rotation position of the mechanical handle 2 corresponds to the rotation angle of the valve rod 52, and corresponds to the control of the water amount entering the mixed water chamber through the water inlet I and the water inlet II.

[0067] Specifically, the two water inlet channels 61 (water inlet channel I and water inlet channel II) in the control box 10 are sealed and communicated with the water outlet I and the water outlet II through two independent connection pipes I and connection pipes II, respectively. The electromagnetic valve I and the electromagnetic valve II control the on-off of the water inlet channel I and the water inlet channel II, respectively. The Hall water flow sensor I and the Hall water flow sensor II monitor the water flow signals of the water inlet channel I and the water inlet channel II, respectively.

[0068] In this embodiment, the user's operation intention is realized by one operation (sensing or mechanical handle 2), and the control logic of opening or closing the faucet is realized.

[0069] 1. After the faucet is installed or the battery is replaced, the control box 10 is connected to the battery power supply. After the power supply is turned on, the initial state is set to the electromagnetic valve I being closed and the electromagnetic valve II being open.

[0070] The controller 7 monitors whether the Hall water flow sensor II generates a feedback signal (whether there is water flow). If there is no feedback signal (at this time, the Hall water flow sensor II has no feedback signal, indicating that the mechanical handle 2 is currently located at position I, the water outlet I is connected, the water outlet II is disconnected, the water inlet channel II has no water flow, and the faucet does not have water), the electromagnetic valve II is kept in an open state, and the initial state adjustment of the faucet is completed this time. Specifically, the mechanical handle 2 is located at position I, the electromagnetic valve I is in a closed state, the electromagnetic valve II is in an open state, and the faucet is in a water-off state.

[0071] If there is a feedback signal (at this time, the Hall water flow sensor II generates a feedback signal, indicating that the mechanical handle 2 is currently located at position II, the water inlet channel II has water flow, and the faucet has water), the controller 7 controls the electromagnetic valve II to be closed and the electromagnetic valve I to be opened, and the initial state adjustment of the faucet is completed this time. Specifically, the mechanical handle 2 is located at position II, the electromagnetic valve I is in an open state, the electromagnetic valve II is in a closed state, and the faucet is in a water-off state.

[0072] The above is the control logic when the faucet is installed or restored to the initial state.

[0073] 2. During normal use, the initial state after adjustment is taken as the reference for convenience of description.

[0074] Before the user intends to have water from the faucet, the state recorded in the built-in memory of the controller 7 is that the electromagnetic valve I is closed, the electromagnetic valve II is opened, and both the Hall water flow sensor I and the Hall water flow sensor II have no water flow signal.

[0075] ① Mechanical handle 2 water-out - mechanical handle 2 water-off control:

The controller 7 records the current water-out state, thereby realizing one-time operation control of the faucet to have water.

[0077] After that, when the user again operates the mechanical handle 2 to switch the current position (from position II to position I), at this time, the water outlet I is connected, the water outlet II is disconnected, the electromagnetic valve I is in a closed state, the Hall water flow sensor I has no water flow signal, and the Hall water flow sensor II has no water flow signal and feeds back to the controller 7. The controller 7 records the current water-off state, thereby realizing one-time operation control of the faucet to have water.

[0078] ② Sensor 4 water-out - sensor 4 water-off control:

[0079] When the user triggers the sensor 4 to send a signal to the controller 7, at this time, the controller 7 inquires that the last valid sensing control instruction before the current sensing operation is to control the electromagnetic valve I to be closed and the electromagnetic valve II to be opened, therefore, the controller 7 sends a control signal to control the electromagnetic valve I to be opened and the electromagnetic valve II to be closed, and needs to receive a feedback signal that the Hall water flow sensor I has a water flow signal, at this time, the electromagnetic valve I is opened, the electromagnetic valve II is closed, the mechanical handle 2 is currently located at position I, the Hall water flow sensor I has a water flow signal, and feeds back to the controller 7, the controller 7 records the current water outlet state, thereby realizing one-time operation control of the faucet to outlet water.

[0080] And thereafter, when the user triggers the sensor 4 to send a signal to the controller 7, the controller 7 inquires that the last valid sensing control instruction before the current sensing operation is to control the electromagnetic valve I to be opened and the electromagnetic valve II to be closed, therefore, the controller 7 sends a control signal to control the electromagnetic valve I to be closed and the electromagnetic valve II to be opened, and needs to receive a feedback signal that the Hall water flow sensor I and the Hall water flow sensor II both have no water flow signal, at this time, the electromagnetic valve I is closed, the electromagnetic valve II is opened, the Hall water flow sensor I and the Hall water flow sensor II both have no water flow signal, and feed back to the controller 7, the controller 7 records the current water outlet state, thereby realizing one-time operation control of the faucet to outlet water.

[0081] ③Sensor 4 water outlet-mechanical handle 2 water closing control:

[0082] When the user triggers the sensor 4 to send a signal to the controller 7, at this time, the controller 7 inquires that the last valid sensing control instruction before the current sensing operation is to control the electromagnetic valve I to be closed and the electromagnetic valve II to be opened, therefore, the controller 7 sends a control signal to control the electromagnetic valve I to be opened and the electromagnetic valve II to be closed, and needs to receive a feedback signal that the Hall water flow sensor I has a water flow signal, at this time, the electromagnetic valve I is opened, the electromagnetic valve II is closed, the mechanical handle 2 is currently located at position I, the Hall water flow sensor I has a water flow signal, and feeds back to the controller 7, the controller 7 records the current water outlet state, thereby realizing one-time operation control of the faucet to outlet water.

[0083] And thereafter, the user operates the mechanical handle 2 to switch the current position (position I to position II), at this time, the water outlet I is disconnected, the water outlet II is connected, the electromagnetic valve I is opened, the electromagnetic valve II is closed, the Hall water flow sensor I and the Hall water flow sensor II both have no water flow signal, and feed back to the controller 7, the controller 7 records the current water outlet state, thereby realizing one-time operation control of the faucet to outlet water.

[0084] ④Mechanical handle 2 water outlet-sensor 4 water closing control:

[0085] When the user operates the mechanical handle 2 to switch the current position (position I to position II), at this time, the water outlet I is disconnected, the water outlet II is connected, the electromagnetic valve II is in an open state, the Hall water flow sensor I has no water flow signal, and the Hall water flow sensor II has a water flow signal and feeds back to the controller 7, and the controller 7 records the current water outlet state, so as to realize one-time operation control of the faucet water outlet.

[0086] And thereafter, when the user triggers the sensor 4 to send a signal to the controller 7, the controller 7 queries that the last valid sensing control instruction before the current sensing operation is to control the electromagnetic valve I to be closed and the electromagnetic valve II to be opened, therefore, the controller 7 sends a control signal to control the electromagnetic valve I to be opened and the electromagnetic valve II to be closed, and needs to receive feedback signals that the Hall water flow sensor I and the Hall water flow sensor II have no water flow signal, at this time, the electromagnetic valve I is opened, the electromagnetic valve II is closed, the Hall water flow sensor I and the Hall water flow sensor II have no water flow signal, and feed back to the controller 7, and the controller 7 records the current water closing state, so as to realize one-time operation control of the faucet water closing.

[0087] The above is the control logic in the normal use process of the faucet. The second initial state has the same control logic as the first initial state, and only the numbering is opposite, which will not be described here.

[0088] 3. When the operation is incorrect, for the convenience of description, the initial state after adjustment is taken as the basis:

[0089] ⑤When the sensing operation is performed and the Hall water flow sensor I and the Hall water flow sensor II both have water flow signal feedback, it is indicated that the mechanical handle 2 is located between position I and position II, and the electromagnetic valve I and II are both in an open state, then the controller 7 selects one of the electromagnetic valves 62 to be closed (in this embodiment, the electromagnetic valve I is selected to be closed);

[0090] ⑥When it is continuously detected that the Hall water flow sensor I and / or the Hall water flow sensor II has water flow signal feedback, and the time exceeds a set threshold value (in this embodiment, the set threshold time is 3 min), then the controller 7 controls the electromagnetic valve 62 corresponding to the Hall water flow sensor to be closed.

[0091] Through the above embodiment, the present application provides a faucet with intelligent double control function, which can conveniently realize the operation intention of the user by one-time operation (sensing or mechanical handle 2), realize opening or closing of the faucet water outlet, and has fault detection and automatic recovery functions, thereby improving the reliability and user experience of the faucet.

[0092] While embodiments of the application have been disclosed in connection with the above specification and drawings this description is not intended to limit the scope of the application and many modifications, enhancements, alternatives, and variations will become apparent to those skilled in the art from this disclosure. Accordingly, it is intended that the application not be limited to the described embodiments, but that it include all variations falling within the scope of the claims, and their equivalents.
