Description

[0001] This utility model relates to the field of faucet equipment technology. More specifically, this utility model relates to a wireless control module for faucets. Background Technology

[0002] Sensor-controlled faucets are becoming increasingly popular in the market because they are convenient and hygienic to operate without contact. However, most sensor faucets on the market have the sensor built into the faucet, which makes them inconvenient to repair, and the sensor's operating position cannot be changed. Many consumers still use traditional mechanical faucets, and if they want to replace them with sensor faucets, they usually need to replace the entire faucet, which is expensive and the disassembly and assembly process is very troublesome.

[0003] Based on the aforementioned technical issues, the utility model patent with authorization announcement number CN221052758U discloses a wireless faucet module that controls the water flow from the source. It separates the originally integrated solenoid valve, control box, and battery box into separate components, and places the wireless sensor externally on the faucet, solving the technical problem of difficult maintenance. However, the above-mentioned patent technology sets up two independent water inlet channels, namely separate control of cold water and hot water, which makes installation more complicated. In addition, the control box in the above-mentioned patent technology is actually just a circuit board that receives wireless signals. Hanging a separate circuit board externally increases the installation process, affects the aesthetics, and lowers the product grade. Utility Model Content

[0030] like Figures 1-5 As shown, this utility model provides a wireless control module for a faucet, which includes:

[0031] The sensing box 2 contains a sensing circuit board 21, which is equipped with an infrared sensor 22 and a wireless signal transmitter 23.

[0032] Solenoid valve box 3, its

[0033] It has two water inlet channels 31, and each water inlet channel 31 is equipped with a corresponding solenoid valve 32 for controlling the opening and closing of the water inlet channel;

[0034] The battery box 4 has a control circuit board 42 and a first battery 41 connected to the solenoid valve 32 via a wire (the battery box 4 has a battery compartment containing four AA batteries, which are the first batteries 41); the control circuit board 42 has a wireless signal receiver, which is wirelessly connected to the wireless signal transmitter 23 (the wireless signal receiver and the wireless signal transmitter 23 are wirelessly connected via 2.4G); when the wireless signal receiver receives the signal transmitted by the wireless signal transmitter 23, the control circuit board 42 controls the wire between the first battery 41 and the solenoid valve 32 to conduct electricity.

[0035] In the above technical solution, the present invention provides a wireless control module for a faucet, which can be installed on the faucet to realize the faucet sensing water output. The faucet structure is the structure disclosed in the prior art. Specifically, the faucet body 1 includes at least a metal bend, a shower head provided at the water outlet end of the metal bend, and a mechanical valve provided inside the metal bend. One end of the mechanical valve is provided with a water inlet pipe that connects to the water inlet of the shower head, and the other end of the water inlet pipe is the water inlet of the faucet body 1.

[0036] The wireless control module for a faucet provided by this utility model includes a sensor box 2, which contains a sensor circuit board 21. The sensor circuit board 21 is equipped with an infrared sensor 22 for sensing user water usage command signals (which can detect the approach of a human body) and a wireless signal transmitter 23 for sending water usage command signals. The wireless control module also includes a solenoid valve box 3 located on the water inlet pipe of the faucet body 1.

[0037] It is equipped with a water inlet channel 31 that communicates with the water inlet on the faucet body 1, and a solenoid valve 32 for controlling the opening and closing of the water inlet channel 31. The water inlet channel 31 connects the water inlet pipe and the drain pipe. Each water inlet channel 31 is equipped with a corresponding solenoid valve 32. Each solenoid valve 32 is electrically connected to a first battery 41 via a wire. The first battery 41 is used to power the solenoid valve 32 and is located in the battery box 4. At the same time, a control circuit board 42 is set in the battery box 4, which is used to control the conduction of the wire between the solenoid valve 32 and the first battery 41, thereby realizing the control of the opening and closing of the solenoid valve 32. Specifically, the control circuit board 42 is equipped with a wireless signal receiver adapted to the wireless signal transmitter 23. When the infrared sensor 22 senses an object approaching (such as when the user needs to use it), the receiver will receive the wireless signal. When the user moves their hand close to the infrared sensor 22, the wireless signal transmitter 23 receives the infrared light information and sends the received signal to the wireless signal receiver. Subsequently, the control circuit board 42 controls the electrical conduction of the wires, the solenoid valve 32 is opened, the water inlet channel 31 is opened, and the water in the drain pipe flows through the water inlet channel 31 and the water inlet pipe, and flows out of the shower head for the user's use. After the wireless signal receiver receives the signal, the control circuit board controls the electrical conduction of the wires momentarily (pulse), (that is, the electrical conduction time of the wires is short, and then it is disconnected, the solenoid valve is closed, and the faucet stops flowing water, so that the faucet flows water once when the user shakes the light-transmitting screen area once, and the water flows for a period of time, such as 5 seconds, and then the faucet stops flowing water), thus realizing the opening and closing of the solenoid valve.

[0038] This utility model provides a technical solution that can transform any mechanically controlled faucet into a sensor-controlled one. The placement of the sensor (sensor box 2) is not limited, and consumers can adjust its position according to actual conditions and the faucet pipe. The control circuit board 42 carrying a wireless signal receiver is placed inside the battery box 4, eliminating the need for an additional control box, reducing the number of devices, and improving the aesthetics of the product installation. This utility model has the advantages of low cost, convenient installation, convenient operation, and convenient maintenance, and also improves the aesthetics and grade of the product.

[0039] In another technical solution, the wireless control module for the faucet has a light-transmitting screen 25 (which is the sensing window of the infrared sensor 22) on one side of the sensing box 2; the sensing box 2 is also provided with a sensing circuit board 21, and the infrared sensor 22 and the wireless signal transmitter 23 are both located on the sensing circuit board 21.

[0040] The sensing box 2 is also provided with a second battery 24, which is used to power the sensing circuit board 21, the infrared sensor 22 and the wireless signal transmitter 23.

[0041] In the above technical solution, the interaction between the infrared sensor 22 and the wireless signal transmitter 23 inside the sensing box 2 is realized by the sensing circuit board 21. After receiving the infrared signal, the infrared sensor 22 needs to convert it into an electrical signal. This electrical signal may be analog or digital, depending on the type of sensor. The circuit on the sensing circuit board 21 can process these raw signals, performing amplification, filtering, analog-to-digital conversion (if the sensor outputs an analog signal), etc., to ensure the quality and accuracy of the signal. The signal processed by the sensing circuit board 21 needs to be transmitted to the wireless signal transmitter 23 inside the battery box 4 through the circuit on the circuit board.

[0042] The sensing box 2 is equipped with a second battery 24 (which can be a 3V button cell battery of type CR2450) for powering the sensing circuit board 21, the infrared sensor 22 and the wireless signal transmitter 23. The sensing circuit board 21 provides the necessary electrical connection to ensure that the signal can be transmitted stably and reliably. The sensing circuit board 21 also typically includes a power management circuit, so that the second battery 24 can be used to provide a stable power supply for the infrared sensor 22 and the wireless signal transmitter 23.

[0043] In another technical solution, the wireless control module for the faucet has two solenoid valves 32 connected to the two output terminals 341 of a Y-shaped wire 34, and the input terminal 342 of the Y-shaped wire 34 connected to the first battery 41.

[0044] In the above technical solution, the solenoid valve 32 is connected to the output end of the first battery 41 via a Y-shaped wire 34. The two branches of the Y-shaped wire 34 serve as the output ends of the wire and are respectively connected to the two solenoid valves 32, while the lower end serves as the input end of the wire and is connected to the output end of the first battery 41.

[0045] The control circuit board contains a pulse circuit switching element (such as a transistor) to control whether the input terminal of the Y-shaped wire is connected to the battery. When the transistor is in saturation, its on-resistance is small, allowing current to flow smoothly, thus connecting the battery to the input terminal of the Y-shaped wire, making the Y-shaped wire electrically conductive, and opening the two solenoid valves. Conversely, when the transistor is in cutoff, its on-resistance is large, preventing current from flowing, disconnecting the battery from the input terminal of the Y-shaped wire, and closing the two solenoid valves. By controlling the saturation and cutoff states of the switching element through the control circuit board, the electrical conduction of the Y-shaped wire can be controlled. Similarly, a mechanical valve on a faucet controls the connection between the hot and cold water pipes, thus determining whether hot or cold water is dispensed from the faucet.

[0046] In another technical solution, the wireless control module for the faucet has one water inlet channel 31 with its inlet end connected to the cold water connection pipe 52 and its outlet end connected to the cold water inlet pipe 12 on the faucet body 1. The other water inlet channel 31 has its inlet end connected to the hot water connection pipe 51 and its outlet end connected to the hot water inlet pipe 11 on the faucet body 1. Each water inlet channel 31 has a filter screen 33 at its inlet end. Specifically, the water inlet channels include cold water and hot water channels to meet the user's needs for different water temperatures. The filter screen 33 at the inlet end is used to filter the water, preventing impurities in the water from entering the solenoid valve 32 and causing it to malfunction.

[0047] In another technical solution, the wireless control module for the faucet includes a button 43 on the battery compartment 4. This button is used to operate the control circuit board 42 and pair the wireless signal receiver on the control circuit board 42 with the wireless signal transmitter 23. Specifically, within 30 seconds of installing the battery, pressing the button on the battery compartment will put the control circuit board into pairing mode for 30 seconds. During this time, the wireless control module will transmit a wireless signal, which the wireless receiver on the battery compartment will receive and pair with. Preferably, the battery compartment also includes an indicator light. Pressing the button once will not illuminate the indicator light, indicating that the battery compartment has been mechanically powered off; pressing the button again will cause the indicator light to flash, indicating that the battery compartment's power supply has returned to normal.

[0048] In another technical solution, the wireless control module for the faucet has a base on one side of the sensor box 2, on which a permanent magnet is mounted. The sensor box 2 is equipped with a metal sheet that magnetically adapts to the permanent magnet and is connected to the mounting surface. The base on the other side of the sensor box 2 is made of plastic; the permanent magnet is mounted on the base. The sensor box can be attracted to the metal sheet (iron sheet) on the mounting surface by the magnet on the base. Preferably, the metal sheet is equipped with double-sided adhesive, allowing the metal sheet to be first adhered to the mounting surface (such as a wall), and then the sensor box can be attracted to the metal sheet by its permanent magnet, achieving detachable installation of the sensor box.

[0049] In another technical solution, the wireless control module for the faucet includes a battery box 4 that is detachably connected to the solenoid valve box 3. One side (back) of the solenoid valve box 3 has a hook side with Velcro. The rough side of the Velcro is attached to the mounting surface (such as a wall or mounting plate) using double-sided adhesive. The solenoid valve box 3 has a hook, and the battery box 4 has a through hole that matches the hook, allowing for a detachable connection between the battery box 4 and the solenoid valve box 3.

[0050] Preferably, the outer surface of the solenoid valve box 3 is marked with water flow direction (such as a water flow arrow), and it is connected to the faucet body according to the water outlet direction to avoid installation errors.

[0051] The wireless communication distance between the wireless transmitter in sensor box 2 and the wireless receiver in battery box 4 is greater than 3 meters.

[0052] The control circuit board is also set so that when the solenoid valve is continuously open for 3 minutes (with an obstacle such as a human hand or other object constantly approaching the light-transmitting screen), the control circuit board disconnects the electrical conduction of the control wire, and the solenoid valve closes. This prevents the sensor from being accidentally triggered, which would cause continuous water discharge and waste water resources.

[0053] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model. Applications, modifications, and variations of this utility model will be readily apparent to those skilled in the art.

[0054] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
