Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control of water outlet of faucets, and more specifically, to an intelligent dual-control faucet and a control method thereof. Background Art

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

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

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

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

[0006] Advanced induction control faucets that adjust water temperature and water volume are usually equipped with complex control box systems. These control boxes integrate multiple drive motors 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 a high degree of customization and comfort, the problem that comes with it is a significant increase in hardware costs. The use of multiple drive motors not only increases the manufacturing cost, but also increases the complexity of subsequent maintenance. In addition, since the control box needs to be powered to operate, most induction faucets use batteries as energy supply in order to maintain the simplicity and portability of the design. However, the energy consumption requirements of multiple drive motors lead to fast battery consumption. Frequent battery replacement not only brings inconvenience to users, but also increases the long-term use cost, especially in public places. This problem is particularly prominent.

DETAILED DESCRIPTION

[0041] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0042] In the description of the present invention, the terms "indicated orientation or positional relationship" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0043] like Figures 1 to 9 As shown, the present invention provides an intelligent dual-control faucet, whose overall structure includes a faucet body 1, a valve body 5, a water transmission structure 6, a controller 7 and other auxiliary components. The following is a detailed description of each part:

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

[0045] The valve body 5 has two water outlets 51, wherein the mechanical handle 2 is connected to the water path switching structure in the valve body 5 through a mechanical linkage mechanism to realize the water outlet control of the two water outlets 51; specifically, the mechanical handle 2 is connected to the valve stem 52 of the valve core 54, and drives the valve stem 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 stem 52 to rotate to adjust the water inlet ratio and water inlet volume of the two water inlets 53, thereby adjusting the water outlet temperature of the water outlet 51.

[0046] The water transmission structure 6 includes two independent water inlet channels 61 and two solenoid valves 62. The two water inlet channels 61 are respectively and independently connected to the two water outlets 51, and each water inlet channel 61 is equipped with a solenoid valve 62 as a control element. The two water inlet channels 61 are connected to a single water outlet channel 63, and the water outlet channel 63 is connected to the water outlet pipe 3. Each solenoid valve 62 respectively regulates the connection 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 equipped 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 where it is located. Specifically, the water flow detector 64 selects a Hall water flow sensor.

[0047] The controller 7 is configured with a state memory module, which can record and store the open and closed states of the two solenoid valves 62 before the sensing operation occurs and the detection result of the last water flow detector 64; wherein, when the sensor 4 detects a preset trigger condition and sends a signal to the controller 7, the controller 7 will select and issue a control instruction opposite to the last sensing control instruction to the corresponding solenoid valve 62 according to the state information (open / closed) of the solenoid valve 62 corresponding to the last valid sensing control instruction before receiving the current signal stored in the controller 7; the controller 7 is the core component of the intelligent dual-control faucet, responsible for receiving the signal of the sensor 4 and issuing control instructions. Specifically, for example, when the user's hand approaches the sensor 4, the sensor 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 a certain operation (such as water discharge), it will first trace back to the open and closed states of the two solenoid valves 62 before the sensing operation, which is achieved by querying the state record stored in the internal memory. According to the state information retrieved and the user's instruction (the signal sent by the sensor 4), the controller 7 generates corresponding control signals and sends them to the solenoid valve 62 through the circuit or interface. These control signals 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 records the opening and closing states of the two solenoid valves 62 and the water flow state before the sensing operation by real-time monitoring and recording the state of the solenoid valve 62, receiving and processing the signal of the sensor 4, backtracking the state information and executing the instruction, and setting the feedback mechanism. These steps and technical elements together ensure the accuracy and reliability of the intelligent control of the faucet, and the intelligent control of the sensor or mechanical handle 2 once can realize the user's operation intention and realize the opening or closing of the faucet.

[0049] Auxiliary components of smart dual-control faucet:

[0050] The battery box assembly 8 has a group of battery cells installed inside, which provide power to the controller 7, the sensor 4, the water flow detector 64 and the solenoid valve 62. The battery box assembly 8 can be easily disassembled and replaced with batteries to ensure the continuous operation of the intelligent dual-control faucet. Since the control box 10 does not need to be equipped with a large number of drive motors, it only needs to power the control components, and the power consumption is slow, and there is no need to frequently replace the battery.

[0051] The water outlet pipe 3 and the telescopic water outlet nozzle 9, the water outlet pipe 3 is a hose, and the water outlet direction and position can be conveniently adjusted. 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 as needed.

[0052] A filter component is provided at the water inlet end of each water inlet channel 61. The filter component is used to remove impurities, particles, etc. in the water to ensure the cleanliness of the water and the safety of the water. Specifically, the filter component is selected from the filter screen 112.

[0053] The control box 10 is a closed shell 101, which integrates the water transmission structure 6 and the controller 7. In this embodiment, the water transmission structure 6 and the controller 7 are integrated inside the shell 101, wherein the two water inlet channels 61 are symmetrically spaced, and the controller 7 and the water outlet channel 63 are arranged in the space between the two water inlet channels 61. The symmetrical setting helps to ensure the uniform distribution of water flow, reduce eddy currents and turbulence, and improve the stability of water outlet. Through the integrated setting, the overall structure is compact and durable, so that the control box 10 can work stably in various environments and is easy to carry and store.

[0054] The housing 101 is sealed with at least three threaded pipe openings 102, which are sealed and connected to the water inlet ends of the two water inlet channels 61 and the outlet ends of the water outlet channels 63 respectively;

[0055] A plurality of quick-connect adapters 103, one end of each quick-connect adapter 103 is a threaded end 104, and the other end is a buckle end 105, and the threaded end 104 is sealed and threadedly connected to the threaded pipe opening 102;

[0056] Two connecting pipes 106, one end of the two connecting pipes 106 is sealed and connected with the two water outlets 51 respectively, and the other end is provided with a snap joint 107, and is sealed and connected with the snap ends 105 of the quick-connect adapters 103 on the two water inlet channels 61 respectively. A snap joint 107 is also provided on the water inlet end of the water outlet pipe 3, and is sealed and connected with the snap end 105 of the quick-connect adapter 103 on the water outlet channel 63.

[0057] At least three threaded pipe openings 102 are sealed and penetrated on the housing 101, which are respectively sealed and connected with the water inlet ends of the two water inlet channels 61 and the outlet ends of the water outlet channels 63. In this embodiment, there are three threaded pipe openings 102. Two quick-connect adapters 103 are used to connect the threaded pipe openings 102 and the connecting pipes 106 to achieve a fast and reliable connection. One end of the two connecting pipes 106 is sealed and connected with the two water outlets 51 respectively, and the other end is connected to the water inlet channel 61 through the quick-connect adapter 103. The water inlet end of the outlet pipe 3 is also connected to the water outlet channel 63 through a quick-connect 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 quick connector interfaces for water inlet and one quick connector interface for water outlet. The quick adapter, the snap connector 107, and the threaded pipe mouth 102 are arranged to facilitate quick and firm connection of the pipeline, and also facilitate disassembly and maintenance, thereby improving convenience and practicality.

[0059] In another technical solution, the controller 7 is configured to have a timing module, which is used to monitor the time from the time when the controller 7 receives the feedback signal, and the time when the feedback signal from the water flow detector 64 is continuously received indicating the existence of water flow. If the time exceeds a set threshold, the operation of closing the solenoid valve 62 is executed.

[0060] In the above technical solution, in some places where water is frequently used but water resources may be wasted due to forgetting to turn off the faucet, such as in daily activities such as washing dishes, washing vegetables, and washing hands, users may forget to turn off the faucet because they are busy with other things, resulting in unnecessary waste of water resources. When the time of water flow (for example, the water flow time exceeds 3 minutes) exceeds a set threshold, the faucet water flow is automatically turned off, so that the faucet is automatically turned off when it is not used for a long time, thereby avoiding waste of water resources.

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

[0062] When the sensor 4 detects a preset trigger condition and sends a signal to the controller 7, the controller 7 will select and issue a control instruction opposite to the last valid sensing control instruction to the corresponding solenoid valve 62 based on the solenoid valve 62 state information corresponding to the last valid sensing control instruction before receiving the current signal stored internally.

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

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

[0065] The controller 7 also monitors the time from issuing the control command to receiving the feedback signal. If the set threshold value (in this embodiment, the threshold value is set to milliseconds) is exceeded and no feedback signal is received (for example, the water outflow operation is sensed, in this embodiment, the feedback signal is a 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 solenoid valve I one by one, and the solenoid valve 62 changes from closed to open), the corresponding water flow detector 64 generates a feedback signal of water flow, and the controller 7 determines that the control command is completed and is a valid control command.

[0066] In this embodiment, specifically, the valve body 5 has two water inlets 53 (water inlet I and water inlet II) and two water outlets 51 (water outlet I and water outlet II), the water inlet I and water inlet II are respectively connected to the hot water source and the cold water source, respectively entering the mixing water chamber in the valve body 5 through the cold water channel 108 and the hot water channel 109, and the water outlet I and water outlet II are selectively connected to the mixing water chamber in the valve body 5 (mixing hot water and cold water, the mixing water chamber is respectively connected to the water outlet I and the water outlet II through the mixing water channel I 110 and the mixing water channel II 111); the position I and the position II of the mechanical handle 2 correspond to the two swing angles of the valve stem 52, respectively corresponding to the water outlet I and the water outlet II being connected to the mixing water chamber; the rotation position of the mechanical handle 2 corresponds to the rotation angle of the valve stem 52, corresponding to the amount of water entering the mixing water chamber from 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 connected with the water outlet Ⅰ and the water outlet Ⅱ respectively through two independent connecting pipes Ⅰ and Ⅱ, and the solenoid valve Ⅰ and the solenoid valve Ⅱ respectively control the on-off of the water inlet channel Ⅰ and the water inlet channel Ⅱ, and the Hall water flow sensor Ⅰ and the Hall water flow sensor Ⅱ respectively monitor the water flow signals of the water inlet channel Ⅰ and the water inlet channel Ⅱ.

[0068] In this embodiment, a detailed description of the control logic of turning on or off the faucet water is realized by realizing the user's operation intention through one operation (sensing or mechanical handle 2):

[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 is turned on, the initial state is set to that the solenoid valve I is closed and the solenoid valve II is open;

[0070] The controller 7 monitors whether the Hall water flow sensor II generates a feedback signal (whether there is water flowing through). 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, there is no water flow in the water inlet channel II, and the faucet does not discharge water), the solenoid valve II is kept in the open state, and the initial state adjustment of the faucet is completed, specifically: the mechanical handle 2 is located at position I, the solenoid valve I is closed, the solenoid valve II is open, and the faucet is in the 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 in position II, water flows through the water inlet channel II, and water flows out of the faucet), the controller 7 controls the solenoid valve II to close and the solenoid valve I to open, and the initial state adjustment of the faucet is completed, specifically: the mechanical handle 2 is in position II, the solenoid valve I is in the open state, the solenoid valve II is in the closed state, and the faucet is in the 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, for the convenience of description, the initial state after adjustment is taken as the benchmark:

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

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

[0076] 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 solenoid valve II is in the open state, the Hall water flow sensor I has no water flow signal, the Hall water flow sensor II has a water flow signal, and the signal is fed back to the controller 7. The controller 7 records the current water outlet state, thereby realizing one-time operation to control the faucet water outlet;

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

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

[0079] When the user triggers the sensor 4 and sends a signal to the controller 7, the controller 7 finds out that the last valid sensing control instruction before the current sensing operation is to control the solenoid valve I to close and the solenoid valve II to open. Therefore, the controller 7 sends a signal to control the solenoid valve I to open and the solenoid valve II to close, and needs to receive a feedback signal from the Hall water flow sensor I that there is a water flow signal. At this time, the solenoid valve I is open, the solenoid valve II is closed, the mechanical handle 2 is currently in position I, the Hall water flow sensor I has a water flow signal, and it is fed back to the controller 7. The controller 7 records the current water outlet status, thereby realizing one-time operation to control the water outlet of the faucet.

[0080] And thereafter, when the user triggers the sensor 4 again and sends a signal to the controller 7, the controller 7 inquires that the last valid sensing control instruction before the current sensing operation was to control the solenoid valve I to open and the solenoid valve II to close. Therefore, the controller 7 sends a signal to control the solenoid valve I to close and the solenoid valve II to open, and needs to receive a signal that both the Hall water flow sensor I and the Hall water flow sensor II have no water flow signal. At this time, the solenoid valve I is closed and the solenoid valve II is opened, and both the Hall water flow sensor I and the Hall water flow sensor II have no water flow signal, and feedback is sent to the controller 7. The controller 7 records the current water-off state, thereby realizing a one-time operation to control the faucet to turn off the water.

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

[0082] When the user triggers the sensor 4 and sends a signal to the controller 7, the controller 7 finds out that the last valid sensing control instruction before the current sensing operation is to control the solenoid valve I to close and the solenoid valve II to open. Therefore, the controller 7 sends a signal to control the solenoid valve I to open and the solenoid valve II to close, and needs to receive a feedback signal from the Hall water flow sensor I that there is a water flow signal. At this time, the solenoid valve I is open, the solenoid valve II is closed, the mechanical handle 2 is currently in position I, the Hall water flow sensor I has a water flow signal, and it is fed back to the controller 7. The controller 7 records the current water outlet status, thereby realizing one-time operation to control the water outlet of the faucet.

[0083] And thereafter, the user operates the mechanical handle 2 to switch the current position (position I switches to position II). At this time, water outlet I is disconnected and water outlet II is connected, solenoid valve I is opened and solenoid valve II is closed, and Hall water flow sensor I and Hall water flow sensor II have no water flow signal, and are fed back to the controller 7. The controller 7 records the current water-off state, thereby realizing one-time operation to control the faucet to turn off the water.

[0084] ④ Mechanical handle 2 water outlet - sensor 4 water off 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 solenoid valve II is in the open state, the Hall water flow sensor I has no water flow signal, the Hall water flow sensor II has a water flow signal, and the signal is fed back to the controller 7. The controller 7 records the current water outlet state, thereby realizing one-time operation to control the faucet water outlet;

[0086] And thereafter, when the user triggers the sensor 4 and sends a signal to the controller 7, the controller 7 inquires that the last valid sensing control instruction before the current sensing operation was to control the solenoid valve I to close and the solenoid valve II to open. Therefore, the controller 7 sends a signal to control the solenoid valve I to open and the solenoid valve II to close, and needs to receive a feedback signal that both the Hall water flow sensor I and the Hall water flow sensor II have no water flow signal. At this time, the solenoid valve I is opened and the solenoid valve II is closed, and both the Hall water flow sensor I and the Hall water flow sensor II have no water flow signal, and feedback is sent to the controller 7. The controller 7 records the current water-off state, thereby realizing one-time operation to control the faucet to turn off the water.

[0087] The above is the control logic of the faucet during normal use. The control logic of the second initial state is the same as that of the first initial state, except that the numbers are reversed, and will not be repeated here.

[0088] 3. When there is an error in operation, for the convenience of description, the initial state after adjustment is used as the benchmark:

[0089] ⑤ After the sensing operation, when both the Hall water flow sensor Ⅰ and the Hall water flow sensor Ⅱ have water flow signal feedback, it means that the mechanical handle 2 is located between position Ⅰ and position Ⅱ, and the solenoid valves Ⅰ and Ⅱ are both in the open state, then the controller 7 selects one solenoid valve 62 to close (in this embodiment, the solenoid valve Ⅰ is selected to close);

[0090] ⑥ When water flow signal feedback is continuously detected from Hall water flow sensor I and / or Hall water flow sensor II, and the time exceeds the set threshold (in this embodiment, the set threshold time is 3 minutes), the controller 7 controls the solenoid valve 62 corresponding to the Hall water flow sensor to close.

[0091] Through the above implementation modes, the present invention provides a faucet with intelligent dual-control function, which can be conveniently operated once (sensing or mechanical handle 2) to realize the user's operating intention, turn on or off the faucet water, and has fault detection and automatic recovery functions, thereby improving the reliability of the faucet and user experience.

[0092] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
