This type of faucet usually combines traditional mechanical operation with advanced induction technology, aiming to provide a more intelligent and user-friendly user experience. However, the induction control faucets widely used in the market still have some technical limitations and user experience deficiencies in design, specifically in the linkage problem between mechanical handle and induction control.
[0003] The existing induction control faucet generally adopts a "dual-mode" operation design, which requires the user to manually open the mechanical handle first to enter standby state, and then use induction (such as infrared induction) to turn on the faucet.

However, in actual use, due to the deep-rooted habit of using mechanical handle to directly control water flow, many users often directly turn off the faucet by operating the mechanical handle after use, rather than using the induction function.

DETAILED DESCRIPTION
[0038] The utility model will be further explained in detail in combination with the drawings, so that the person skilled in the art can implement according to the specification text.
[0039] In the description of the utility model, the orientation or position relation indicated is based on the orientation or position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and is not indicated or implied that the indicated device or element must have a particular orientation, configuration and operation, therefore, it cannot be understood as the limitation of the utility model.
[0040] As Figures 1-9 The utility model provides a kind of intelligent double-control faucet, comprising:
[0041] A faucet body is provided with a mechanical handle, a water outlet pipe and a sensor. The faucet body is the main part of the intelligent double-control faucet. The user can select one of the two water outlets for water control by operating the mechanical handle. The water outlet pipe is used to discharge the water treated by the valve body and the water body transmission structure. The sensor is used to detect the user's operation and generate signals to send to the controller. The sensor is used to detect the user's operation and generate signals to send to the controller. These signals may include the user's touch, proximity or movement, etc. Specifically, the sensor is selected from an infrared sensor, a touch sensor or a proximity sensor. In this embodiment, the sensor is an infrared sensor and is arranged on the side of the faucet body opposite the mechanical handle to ensure that the user can conveniently control the faucet through the sensing operation.
[0042] A valve body has two water outlets. The mechanical handle is connected to the waterway switching structure in the valve body through a mechanical linkage mechanism to realize selective water control of the two water outlets. Specifically, the mechanical handle is connected to the valve stem of the valve core to drive the valve stem to swing and select the water outlet. Preferably, the valve body has two water inlets corresponding to two different water inlet modes (such as cold water and hot water). The mechanical handle drives the valve stem to rotate to adjust the water inlet ratio and water inlet amount of the two water inlets, thereby adjusting the water outlet temperature of the water outlet.
[0043] A water body transmission structure includes two independent water inlet channels, each corresponding to an independent connection with two water outlets. Each water inlet channel is provided with an electromagnetic valve as a control element. The two water inlet channels are connected to a single water outlet channel. Each electromagnetic valve controls the communication state between the water inlet channel and the water outlet channel. The water outlet channel is connected to the water outlet pipe. Each water inlet channel is provided with a water flow detector to detect whether there is water flow in the water inlet channel.
[0044] A controller is connected to the electromagnetic valve and the water flow detector.
[0045] In the technical scheme, the mechanical handle on the faucet body is connected with the waterway switching structure in the valve body through a mechanical linkage mechanism. The mechanical connection mode is stable and reliable, and no additional electronic debugging is required during installation, thereby further improving the convenience of installation. The mechanical handle on the faucet body and the waterway switching structure in the valve body adopt a mechanical linkage mode, and no complex electronic control system is required, thereby reducing the failure rate and improving the overall reliability. The mechanical handle on the faucet body allows the user to manually select any one of the two water outlets for water control. The manual adjustment mode is intuitive and easy to understand, and the user can easily get started without learning complex operation steps. The two electromagnetic valves are responsible for controlling the opening and closing of the two water inlet channels, and no water temperature adjustment is required. This design allows the user to enjoy the convenience of intelligent control while still retaining the flexibility of manual adjustment. When the electromagnetic valve is opened, the user can adjust the water temperature change through the mechanical handle. Therefore, the mechanical structure design of the intelligent double-control faucet has significant technical effects in terms of structure space optimization, installation convenience, simple and reliable structure, and the convenience of manual adjustment and electric control combination, thereby providing the user with a more convenient, efficient and reliable water experience.
[0046] Therefore, in the above technical scheme, the valve body has two water outlets, and the two water outlets are selected by operating a mechanical handle for water control. The water body transmission structure includes two independent water inlet channels, and the two water inlet channels are respectively connected with the two water outlets. The opening and closing states of the two electromagnetic valves are always opposite, which can provide a mechanical structure basis for one operation (mechanical or induction) to realize faucet water or water off.
[0047] In another technical scheme, the battery box assembly includes a battery box and a group of battery units installed in the battery box. The battery units supply power to the controller, the water flow detector and the electromagnetic valve.
[0048] In the above technical scheme, the battery box assembly can be easily disassembled and replaced with a battery to ensure the continuous operation of the intelligent double-control faucet. Since the control box does not need to be provided 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 frequently replaced.
[0049] In another technical scheme, the housing has at least three threaded pipe openings, and the water inlet ends of the two water inlet channels and the water outlet ends of the water outlet channels are respectively in sealed communication with the ports in the housing. The water body transmission structure and the controller are arranged in the housing to form a control box.
[0050] In the above technical solution, the control box is closely integrated with the faucet body, at least three threaded pipe openings are sealed on the shell to realize direct and compact connection of the water transmission structure and the external water pipe, and the installation space is greatly saved. The mechanical handle, the water outlet pipe and the sensor on the faucet body are reasonably arranged, do not occupy additional space, and at the same time ensure the convenience and beauty of operation. The connection between the control box and the faucet body is realized through the sealed threaded pipe opening, and during installation, complex debugging and calibration are not required, only the water pipe needs to be simply connected and tightened with the threaded pipe openings on the control box and the faucet body, thereby greatly simplifying the installation process.
[0051] In another technical solution, it also includes:
[0052] A plurality of quick connection adapters, one end of the quick connection adapter is a threaded end, the other end is a buckle end, the threaded end is sealed and screwed with the threaded pipe opening;
[0053] Two connecting pipes, one end of each of the two connecting pipes is in sealed communication with the two water outlets respectively, and the other end of each of the two connecting pipes is provided with a clamping joint, the clamping joint is in sealed connection with the buckle end of the corresponding quick connection adapter;
[0054] The water outlet end of the connecting pipe is provided with a clamping joint, and the clamping joint is in sealed connection with the buckle end of the corresponding quick connection adapter;
[0055] The water inlet end of the water outlet pipe is also provided with a clamping joint, and the clamping joint is in sealed connection with the buckle end of the corresponding quick connection adapter.
[0056] In the above technical solution, the design of the quick connection adapter makes the connection process extremely simple, the user only needs to simply connect and lock the buckle end with the corresponding clamping joint, and the connection can be completed, without the need for complex tools or cumbersome steps. Similarly, the disassembly process is also very fast, only by pressing the unlocking device, the connection can be easily separated, thereby greatly improving the work efficiency. Since the design of the quick connection adapter makes the connection and disassembly very simple, when maintaining or replacing parts, the user can easily disassemble and reinstall the related components, thereby greatly reducing the maintenance difficulty and time cost.
[0057] In another technical solution, the sensor is an infrared sensor, and is arranged on the side of the faucet body opposite to the mechanical handle, so as to ensure that the user can conveniently control the faucet through the sensing operation.
[0058] In another technical solution, the water outlet pipe is a flexible pipe, which can conveniently adjust the water outlet direction and position. The water outlet pipe is connected with a telescopic water outlet nozzle, and the user can adjust the length and angle of the water outlet nozzle according to the needs.
[0059] In another technical solution, a filter screen is arranged on the threaded pipe opening located on the water inlet channel. The filter screen is used to remove impurities, particulate matter and the like in the water to ensure the cleanliness of the water quality and the safety of the water use.
[0060] In another technical solution, the controller is configured to have a state memory module capable of recording and storing the opening and closing states of the two electromagnetic valves before the induction operation occurs and the detection result of the last water flow detector.
[0061] The controller is the core component of the intelligent double-control faucet, responsible for receiving signals from the inductor and issuing control instructions. Specifically, for example, the user's hand approaches the inductor, the inductor detects the trigger condition and sends a signal to the controller. Specifically, the state memory module is selected as the internal memory of the controller. When the controller needs to perform an operation (such as water output), it will first backtrack to the opening and closing states of the two electromagnetic valves 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 instructions (signals sent by the inductor), the controller will generate corresponding control signals and send them to the electromagnetic valves through the circuit or interface. These control signals will change the coil current, voltage or magnetic field of the electromagnetic valve, thereby controlling the opening and closing of the electromagnetic valve.
[0062] In the above technical solution, the controller monitors and records the state of the electromagnetic valve in real time, receives and processes the signals from the inductor, backtracks the state information and executes the instructions, and sets up a feedback mechanism to record the opening and closing states of the two electromagnetic valves 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 and the intelligent control of the induction or mechanical handle of a single operation, that is, the user's operation intention is realized, and the faucet is opened or closed.
[0063] In another technical solution, the controller is configured to have a timing module for monitoring the time from when the controller receives the feedback signal to when the feedback signal of the water flow detector is continuously received as there is water flow. If the time exceeds the set threshold, the operation of closing the electromagnetic valve is performed.
[0064] In the above technical solution, some places need frequent water but may cause water resource waste due to forgetting to close the faucet, such as in daily activities of washing dishes, washing vegetables, washing hands, etc. 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 water flow time exceeding 3 minutes) exceeds a set threshold, the faucet water flow is automatically closed, the faucet is automatically closed when not used for a long time, and waste of water resources is avoided.
[0065] Based on the structure of the above-mentioned intelligent double-control faucet, the utility model discloses a control method of intelligent double-control faucet. The method comprises the following steps:
[0066] When the inductor detects the preset trigger condition and sends a signal to the controller, the controller will select and send a control instruction opposite to the last effective induction control instruction to the corresponding electromagnetic valve according to the electromagnetic valve state information corresponding to the last effective induction control instruction stored in the controller before receiving the current signal.
[0067] In the above technical solution, when the inductor detects the preset trigger condition (such as the user's hand close to the inductor) and sends a signal to the controller, the controller starts to work.
[0068] The controller selects and sends a control instruction opposite to the last effective induction control instruction to the corresponding electromagnetic valve according to the electromagnetic valve state information corresponding to the last effective induction control instruction stored in the controller before receiving the current signal. For example, if the effective induction control instruction is electromagnetic valve I opening and electromagnetic valve II closing, the induction operation this time will close electromagnetic valve I and open electromagnetic valve II.
[0069] The controller simultaneously monitors the time from sending the control instruction to receiving the feedback signal. If the feedback signal (such as the induction water operation, in this embodiment, the feedback signal is the water flow signal sent by the Hall water flow sensor, when there is water flow in the water inlet channel I (the water inlet channel I corresponds to the electromagnetic valve I one-to-one, and the electromagnetic valve changes from closing to opening), the corresponding water flow detector generates a feedback signal indicating that there is water flow, and the controller judges that this control instruction is completed and is an effective control instruction) is not received within a set threshold (in this embodiment, the threshold is set to milliseconds).
[0070] In the embodiment, specifically, two water inlets (water inlet I, water inlet II) and two water outlets (water outlet I, water outlet II) of the valve body, the water inlet I and the water inlet II are communicated with the hot water source and the cold water source respectively, and enter the mixed water cavity in the valve body through the cold water channel and the hot water channel respectively, the water outlet I and the water outlet II are selectively communicated with the mixed water cavity (mixed hot water and cold water, the mixed water cavity is communicated with the water outlet I and the water outlet II through the mixed water channel I and the mixed water channel II respectively) in the valve body; the position I and the position II of the mechanical handle correspond to two swing angles of the valve rod respectively, and correspond to the communication state of the water outlet I and the water outlet II with the mixed water cavity respectively; the rotation position of the mechanical handle corresponds to the rotation angle of the valve rod, and corresponds to the water amount of the water inlet I and the water inlet II entering the mixed water cavity.
[0071] Specifically, two water inlets (water inlet I, water inlet II) in the control box, the water inlet I and the water inlet II are sealed and communicated with the water outlet I and the water outlet II through two independent connecting pipes I and connecting pipes II respectively, the electromagnetic valve I and the electromagnetic valve II control the on-off of the water inlet I and the water inlet II respectively, and the Hall water flow sensor I and the Hall water flow sensor II monitor the water flow signals of the water inlet I and the water inlet II respectively.
[0072] In the embodiment, the operation intention of the user is realized through one operation (induction or mechanical handle), and the control logic of opening or closing the faucet water outlet is realized.
[0073] 1. After the faucet is installed or the battery is replaced, the control box is communicated with the battery power supply, after the power supply is turned on, the initial state is set to be that the electromagnetic valve I is in the closed state and the electromagnetic valve II is in the opened state.
[0074] The controller 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, which indicates that the mechanical handle is currently located at the position I, the water outlet I is connected, the water outlet II is disconnected, the water inlet II has no water flow, and the faucet does not have water), the electromagnetic valve II is kept in the opened state, and the initial state adjustment of the faucet is completed, specifically, the mechanical handle is located at the position I, the electromagnetic valve I is in the closed state, the electromagnetic valve II is in the opened state, and the faucet is in the water-off state.
[0075] If there is a feedback signal (at this time, the Hall water flow sensor II generates a feedback signal, which indicates that the mechanical handle is currently located at the position II, the water inlet II has water flow, and the faucet has water), the controller controls the electromagnetic valve II to be closed and the electromagnetic valve I to be opened, the initial state adjustment of the faucet is completed, specifically, the mechanical handle is located at the position II, the electromagnetic valve I is in the opened state, the electromagnetic valve II is in the closed state, and the faucet is in the water-off state.
[0076] The above is the control logic when the faucet is installed or the initial state is restored.
[0077] 2. During normal use, for the convenience of description, the initial state after adjustment is taken as the reference:
[0078] The user intends to turn on the faucet. Before operation, the state recorded in the controller's built-in memory is: electromagnetic valve I is closed, electromagnetic valve II is opened, and both Hall water flow sensor I and Hall water flow sensor II are water flow signal-free:
[0079] ①Mechanical handle water turning on - mechanical handle water turning off control:
[0080] When the user operates the mechanical handle to switch the current position (position I to position II), at this time, water outlet I is disconnected, water outlet II is connected, electromagnetic valve II is in the opened state, Hall water flow sensor I is water flow signal-free, and Hall water flow sensor II has a water flow signal and feeds back to the controller. The controller records the current water turning on state, thereby realizing one-time operation control of the faucet water turning on.
[0081] After that, when the user again operates the mechanical handle to switch the current position (position II back to position I), at this time, water outlet I is connected, water outlet II is disconnected, electromagnetic valve I is in the closed state, Hall water flow sensor I is water flow signal-free, and Hall water flow sensor II is water flow signal-free, and feeds back to the controller. The controller records the current water turning off state, thereby realizing one-time operation control of the faucet water turning off.
[0082] ②Sensor water turning on - sensor water turning off control:
[0083] When the user triggers the sensor to send a signal to the controller, at this time, the controller queries that the last valid sensor control instruction before the current sensor operation is to control electromagnetic valve I to be closed and electromagnetic valve II to be opened. Therefore, the controller issues a control instruction to control electromagnetic valve I to be opened and electromagnetic valve II to be closed, and needs to receive a feedback signal that Hall water flow sensor I has a water flow signal. At this time, electromagnetic valve I is opened, electromagnetic valve II is closed, the mechanical handle is currently located at position I, Hall water flow sensor I has a water flow signal, and feeds back to the controller. The controller records the current water turning on state, thereby realizing one-time operation control of the faucet water turning on.
[0084] And after that, when the user again triggers the sensor to send a signal to the controller, the controller queries that the last valid sensor control instruction before the current sensor operation is to control electromagnetic valve I to be opened and electromagnetic valve II to be closed. Therefore, the controller issues a control instruction to control electromagnetic valve I to be closed and electromagnetic valve II to be opened, and needs to receive a feedback signal that both Hall water flow sensor I and Hall water flow sensor II are water flow signal-free. At this time, electromagnetic valve I is closed, electromagnetic valve II is opened, Hall water flow sensor I and Hall water flow sensor II are water flow signal-free, and feeds back to the controller. The controller records the current water turning off state, thereby realizing one-time operation control of the faucet water turning off.
[0085] ③ Sensor water - mechanical handle off water control:
[0086] When the user triggers the sensor, sends a signal to the controller, at this time, the controller query to the last valid induction control instruction before the current induction operation is to control the electromagnetic valve I closed, electromagnetic valve II open, therefore, the controller sends control electromagnetic valve I open, electromagnetic valve II closed, and need to receive the feedback signal of the Hall water flow sensor I water flow signal, at this time, electromagnetic valve I open, electromagnetic valve II closed, the mechanical handle is currently located in position I, Hall water flow sensor I water flow signal, and feedback to the controller, the controller records the current water state, thereby realizing a operation control faucet water.
[0087] And thereafter, the user operates the mechanical handle 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 open, the electromagnetic valve II is closed, the Hall water flow sensor I and the Hall water flow sensor II are both no water flow signal, and feedback to the controller, the controller records the current water state, thereby realizing a operation control faucet water.
[0088] ④ Mechanical handle water - sensor off water control:
[0089] When the user operates the mechanical handle 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 open, the Hall water flow sensor I is no water flow signal, the Hall water flow sensor II is water flow signal, and feedback to the controller, the controller records the current water state, thereby realizing a operation control faucet water;
[0090] And thereafter, when the user triggers the sensor, sends a signal to the controller, the controller query to the last valid induction control instruction before the current induction operation is to control the electromagnetic valve I closed, electromagnetic valve II open, therefore, the controller sends control electromagnetic valve I open, electromagnetic valve II closed, and need to receive the feedback signal of the Hall water flow sensor I and the Hall water flow sensor II are both no water flow signal, at this time, electromagnetic valve I open, electromagnetic valve II closed, the Hall water flow sensor I and the Hall water flow sensor II are both no water flow signal, and feedback to the controller, the controller records the current water state, thereby realizing a operation control faucet water.
[0091] The above is the control logic of the faucet in the normal use process. The second initial state is the same as the first initial state control logic, only the number is opposite, not described here.
[0092] 3, when the operation is wrong, for the convenience of description, all based on the initial state of the adjustment is completed:
[0093] ⑤When the induction operation is performed, if the water flow signal feedbacks from both the Hall water flow sensor I and the Hall water flow sensor II, it means that the mechanical handle is between the position I and the position II, and the electromagnetic valves I and II are both open, then the controller closes one of the electromagnetic valves (in this embodiment, the electromagnetic valve I is closed);
[0094] ⑥When the water flow signal feedbacks from the Hall water flow sensor I and / or the Hall water flow sensor II is continuously detected for more than the set threshold time (in this embodiment, the set threshold time is 3 minutes), the controller controls the corresponding electromagnetic valve of the Hall water flow sensor to be closed.
[0095] Through the above embodiments, the intelligent double-control faucet can conveniently realize the operation intention of the user by one operation (induction or mechanical handle), realize the opening or closing of the faucet, and has the fault detection and automatic recovery functions, thereby improving the reliability and user experience of the faucet.
[0096] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, and it can be fully applied to various fields suitable for the present application. For those skilled in the art, other modifications can be easily realized, and therefore the present application is not limited to specific details and the figures shown and described herein.
