Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and in particular to an intelligent sensor-based contactless water dispenser. Background Technology

[0002] In today's daily life, water dispensers are essential for people to obtain drinking water in various public places such as homes, offices, schools, hospitals, and shopping malls. However, traditional water dispensers have revealed many drawbacks over long-term use.

[0003] From an operational convenience perspective, traditional water dispensers typically rely on users manually pressing a faucet or rotating a knob to dispense cold or hot water. In a home setting, this can be difficult for the elderly, children, or people with disabilities, and there's even a risk of spilled water or burns due to improper force. More seriously, there are hygiene and health concerns. Since the faucet of a traditional water dispenser is a frequently touched surface, in high-traffic areas such as school classrooms, hospital waiting areas, and shopping mall rest areas, many different people may use the same dispenser within a short period. Bacteria, viruses, and other microorganisms carried on each person's hands can easily remain after touching the faucet, leading to cross-infection and the spread of various diseases, posing a significant threat to public health and safety.

[0004] Furthermore, traditional water dispensers lack precise and effective sensing devices. On the one hand, they cannot intelligently sense whether the cup is in place. Sometimes, if the user's cup is slightly misplaced, water may spill out of the cup, wetting the table, wasting water and requiring extra cleaning. On the other hand, they cannot accurately determine the user's water needs. For example, if the user only briefly approaches the water dispenser without intending to fill it, water may automatically flow out due to accidental touch or misjudgment, causing unnecessary water waste. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned problems and provide an intelligent sensor-based contactless water dispenser.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The intelligent sensor-activated contactless water dispenser includes a casing, an ultrasonic ranging module, a water dispensing device, an indicator light module, and a bracket. The ultrasonic ranging module is installed inside the casing, a location that protects it from direct external interference, ensuring accurate ranging and facilitating electrical connection and collaborative operation with other internal components. It detects the distance between surrounding objects and the dispenser by emitting and receiving ultrasonic waves, which is crucial for the intelligent sensing function. Based on this distance information, it determines whether the water cup is in place and triggers the corresponding water dispensing action.

[0008] The water outlet is rigidly installed at the top of the groove in the middle of the casing. This stable installation method ensures that the water outlet will not easily shake or shift during frequent daily use, ensuring smooth and stable water flow and avoiding problems such as leakage or uneven water flow caused by shaking. The water outlet includes hot and cold water taps to meet the diverse drinking water temperature needs of users.

[0009] The indicator light module is embedded in the upper surface of the casing in a conspicuous position, making it easy for users to observe at any time. It consists of light-emitting diodes and provides intuitive feedback to users on the current working status of the water dispenser through different on / off or flashing states, such as whether cold water is ready or hot water is being dispensed, which greatly improves the convenience of user operation and reduces the probability of misoperation.

[0010] Furthermore, the bracket is located at the bottom of the groove, providing a dedicated area for users to place their water cups. Its reasonable height and size design can accommodate water cups of different sizes, allowing users to easily fill their cups without having to adjust their position. On the other hand, the position of the bracket is coordinated with the layout of the ultrasonic ranging module, so that when a water cup is placed on it, the ultrasonic sensor can accurately capture the information of the water cup and trigger the subsequent intelligent control process.

[0011] The casing also includes a control module, a relay module, a solenoid valve module, and a power supply module. The relay module is electrically connected to the control module, converting the weak electrical control signals from the control module into strong electrical drive signals to drive the solenoid valve. This connection method allows the control module to indirectly but effectively control the opening and closing of the solenoid valve, thereby controlling the flow of water and precisely controlling the output of cold or hot water to meet the user's water connection needs.

[0012] The solenoid valve module is connected to a relay module and a power module at both ends. This connection design allows the solenoid valve to obtain the necessary working power from the power module under the drive of the relay. When it receives the action signal from the relay, it quickly switches its own state to open or close the hot and cold water outlet passages. The cold water solenoid valve and the hot water solenoid valve are controlled independently to ensure that users can obtain cold or hot water as needed, which greatly improves the convenience and flexibility of use.

[0013] Furthermore, the power module, as the energy source of the entire system, provides stable and compatible power for the electrical connection of the control module, relay module, and solenoid valve module. It not only ensures the power supply required for the normal operation of each component, but also resists the impact of mains power fluctuations with its own voltage regulation and filtering functions, so that each electrical component can work in a stable voltage environment, ensuring the reliability and stability of the entire water dispenser system and avoiding failures caused by power problems.

[0014] The control module uses an Arduino Uno microcontroller, whose power pins are electrically connected to the power module via wires. The Arduino Uno microcontroller has abundant interface resources and powerful processing capabilities, making it very suitable as the control unit of a small intelligent control system. Its power pins are directly connected to the power module via wires, ensuring a stable and reliable power supply. This ensures that the microcontroller can run continuously, process signals from various sensors and modules in an orderly manner, make accurate decisions in real time, and maintain the intelligent operation of the entire water dispenser system.

[0015] The relay module includes a first relay and a second relay. The control pins of the first relay and the second relay are connected to the control port of the Arduino Uno microcontroller via wires. This one-to-one connection allows the microcontroller to independently and precisely control the two relays. When the microcontroller determines whether the user needs cold or hot water based on the cup position information received from the ultrasonic ranging module, it sends a control signal to the corresponding relay, allowing the relay to precisely drive the subsequent water circuit to switch on and off, thus achieving precise switching between hot and cold water.

[0016] The solenoid valve module includes a cold water solenoid valve and a hot water solenoid valve. One end of the cold water solenoid valve is connected to the output terminal of the first relay, and the other end is connected to the power module. One end of the hot water solenoid valve is connected to the output terminal of the second relay, and the other end is connected to the power module. The ultrasonic ranging module includes a first ultrasonic sensor, a second ultrasonic sensor, a third ultrasonic sensor, and a fourth ultrasonic sensor. The first and second ultrasonic sensors are symmetrically arranged on the left and right sides of the groove, while the third and fourth ultrasonic sensors are located at the top of the groove. This omnidirectional, multi-angle arrangement can capture the position information of the water cup from multiple dimensions. Whether the water cup is approached from the side or placed above, the sensors can keenly detect it and feed the distance data back to the control module in real time. By accurately measuring the round-trip time of the ultrasonic waves to calculate the distance, a solid data foundation is provided for the system to accurately determine whether the water cup is in place and its position status, thereby triggering the corresponding water dispensing process.

[0017] Furthermore, the water outlet device includes a hot water faucet and a cold water faucet. The water outlet paths of the hot water faucet and the cold water faucet are controlled by a hot water solenoid valve and a cold water solenoid valve, respectively. The cold water faucet is made of food-grade materials to ensure that the cold water is not contaminated and that the water flow is smooth and stable. In addition to ensuring smooth water flow, the hot water faucet is also equipped with an anti-scalding design to prevent users from being accidentally scalded when they get hot water, thus ensuring the safety and comfort of users from a hardware perspective.

[0018] The indicator light module includes a first indicator light and a second indicator light. The first and second indicator lights are connected to an Arduino Uno microcontroller and a power module respectively via wires. The microcontroller sends control signals to the indicator light module based on the system's operating status, such as the preparation of cold and hot water, and whether water is being dispensed. This causes the indicator light to light up, turn off, or flash, providing intuitive visual feedback to the user about the water dispenser's current operating status. This clear visual feedback reduces operational errors and greatly improves the convenience of human-computer interaction.

[0019] The advantages of this utility model are:

[0020] 1. This utility model achieves intelligent sensing through an ultrasonic ranging module, eliminating the need for manual operation of the faucet and greatly improving ease of use, especially suitable for people with busy hands or limited mobility. It also avoids the risk of cross-infection from multiple people manually touching the faucet, providing strong protection for public health and aligning with modern healthy living concepts.

[0021] 2. This utility model effectively prevents water waste through a precise sensing and control mechanism. Water is dispensed only when a water cup is detected and the user needs to fill it, which is energy-saving and environmentally friendly. The safety measure of automatically stopping the water after 8 seconds not only avoids water waste caused by forgetting to turn off the tap, but also prevents flooding in special situations such as when no one is on duty, thus improving the safety and reliability of the water dispenser.

[0031] The present invention will be described in detail below through specific embodiments to enable a better understanding of the present invention. However, the following embodiments do not limit the scope of protection of the present invention.

[0032] Example 1

[0033] This embodiment discloses an intelligent sensor-based contactless water dispenser.

[0034] like Figure 1-3As shown, the intelligent sensor-based contactless water dispenser includes a housing 1, an ultrasonic ranging module 2, a water dispensing device 3, an indicator light module 4, and a bracket 5; the ultrasonic ranging module 2 is installed inside the housing 1; the water dispensing device 3 is rigidly installed at the top of a groove in the middle of the housing 1; the indicator light module 4 is embedded in the upper surface of the housing 1; and the bracket 5 is located at the bottom of the groove.

[0035] The casing 1, as the outer shell of the entire water dispenser, protects the internal components from external environmental influences, such as preventing dust and moisture intrusion and resisting a certain degree of physical impact. At the same time, the internal cavity provides space for other key components and is the physical foundation of the entire system. Its material selection and size design are closely related to the functionality and stability of the water dispenser.

[0036] The ultrasonic ranging module 2 is installed inside the housing 1. This location design not only protects it from direct external interference, ensuring the accuracy of the ranging, but also facilitates electrical connection with other internal components for collaborative operation. Detecting the distance between the water dispenser and surrounding objects by emitting and receiving ultrasonic waves is key to achieving the intelligent sensing function. This distance information is then used to determine if the water cup is in place, thereby triggering the corresponding water dispensing action.

[0037] Furthermore, the water outlet device 3 is rigidly installed at the top of the groove in the middle of the casing 1. This stable installation method ensures that the water outlet device will not easily shake or shift during frequent daily use, ensuring smooth and stable water flow and avoiding problems such as leakage or uneven water flow caused by shaking. The water outlet device 3 includes hot and cold water taps to meet the diverse drinking water temperature needs of users.

[0038] The indicator light module 4 is embedded in the upper surface of the casing 1 in a conspicuous position, making it easy for users to observe at any time. Composed of light-emitting diodes, it intuitively provides users with feedback on the current working status of the water dispenser through different on / off or flashing states, such as whether cold water is ready or hot water is being dispensed, greatly improving the convenience of user operation and reducing the probability of misoperation.

[0039] The bracket 5 is located at the bottom of the groove, providing a dedicated area for users to place their water cups. Its reasonable height and size design can accommodate water cups of different sizes, allowing users to easily fill their cups without having to adjust their position. On the other hand, the position of the bracket is coordinated with the layout of the ultrasonic ranging module, so that when a water cup is placed on it, the ultrasonic sensor can accurately capture the information of the water cup and trigger the subsequent intelligent control process.

[0040] Furthermore, the housing 1 also includes a control module 11, a relay module 12, a solenoid valve module 13, and a power module 14; the relay module 12 is electrically connected to the control module 11; the two ends of the solenoid valve module 13 are respectively connected to the relay module 12 and the power module 14; the power module 14 is electrically connected to the control module 11, the relay module 12, and the solenoid valve module 13; the ultrasonic ranging module 2 and the indicator light module 4 are electrically connected to the control module 11.

[0041] The control module 11 bears the most critical responsibility for control and signal processing. Electrically connected to the relay module 11, it sends precise commands to the relay to control the on / off state of subsequent circuits. Electrically connected to the ultrasonic ranging module 2 and the indicator light module 4, it can receive distance data from the ultrasonic ranging module 2 in real time to determine the water cup's status. Simultaneously, it issues display commands to the indicator light module based on system operation, allowing the user to intuitively understand the water dispenser's working status. Its connection to the power module 14 ensures a stable power supply, maintaining efficient computing and control capabilities, continuously processing various input and output signals, and guaranteeing the intelligent operation of the entire water dispenser.

[0042] The relay module 12 is closely connected to the control module 11 on one hand to receive control commands, and on the other hand, it is connected to the solenoid valve module 13 to convert the weak electrical control signal sent by the control module into a strong electrical drive signal to drive the solenoid valve. This connection method allows the control module 11 to indirectly but effectively control the opening and closing of the solenoid valve, thereby controlling the flow of water and accurately controlling the output of cold or hot water to meet the user's water connection needs.

[0043] Furthermore, the solenoid valve module 13 is connected to the relay module 12 and the power module 14 at its two ends, respectively. This connection design allows the solenoid valve to obtain the necessary operating power from the power module 14 under the drive of the relay. When it receives an action signal from the relay, it quickly switches its own state, opening or closing the hot and cold water outlet passages. The cold water solenoid valve and the hot water solenoid valve are controlled independently, ensuring that users can obtain cold or hot water as needed, greatly improving the convenience and flexibility of use.

[0044] The power module 14 serves as the energy source for the entire system, providing stable and compatible power for the electrical connections of the control module 11, relay module 12, and solenoid valve module 13. It not only ensures the power supply required for the normal operation of each component but also, through its voltage stabilization and filtering functions, resists the effects of mains power fluctuations, enabling each electrical component to operate in a stable voltage environment. This ensures the reliability and stability of the entire water dispenser system and prevents malfunctions caused by power problems.

[0045] The control module 11 uses an Arduino Uno microcontroller, and its power pins are electrically connected to the power module 14 via wires.

[0046] The Arduino Uno microcontroller has abundant interface resources and powerful processing capabilities, making it very suitable as the control unit of a small intelligent control system. Its power pin is directly connected to the power module 14 through wires, ensuring a stable and reliable power supply. This ensures that the microcontroller can run continuously, process signals from various sensors and modules in an orderly manner, make accurate decisions in real time, and maintain the intelligent operation of the entire water dispenser system.

[0047] The relay module 12 includes a first relay and a second relay; the control pins of the first and second relays are respectively connected to the control ports of the Arduino Uno microcontroller via wires. This one-to-one connection allows the microcontroller to independently and precisely control the two relays. When the microcontroller determines whether the user needs cold or hot water based on the cup position information received from the ultrasonic ranging module 2, it sends a control signal to the corresponding relay, causing the relay to precisely drive the subsequent water circuit on / off action, achieving accurate switching between hot and cold water output.

[0048] Furthermore, the solenoid valve module 13 includes a cold water solenoid valve and a hot water solenoid valve; one end of the cold water solenoid valve is connected to the output terminal of the first relay, and the other end is connected to the power module 14; one end of the hot water solenoid valve is connected to the output terminal of the second relay, and the other end is connected to the power module 14. This connection layout allows the solenoid valves to respond quickly under the control of the relays, opening or closing the cold and hot water outlet passages. Furthermore, because the cold and hot water solenoid valves are controlled separately, it ensures that the water outlet system can accurately execute different water temperature requirements selected by the user, improving the user's water connection experience.

[0049] The ultrasonic ranging module 2 includes a first ultrasonic sensor 21, a second ultrasonic sensor 22, a third ultrasonic sensor 23, and a fourth ultrasonic sensor 24. The first ultrasonic sensor 21 and the second ultrasonic sensor 22 are symmetrically arranged on the left and right sides of the groove; the third ultrasonic sensor 23 and the fourth ultrasonic sensor 24 are located at the upper end of the groove. This omnidirectional, multi-angle arrangement can capture the position information of the water cup from multiple dimensions.

[0051] The indicator module 4 includes a first indicator light 41 and a second indicator light 42; the first indicator light 41 and the second indicator light 42 are respectively connected to the Arduino Uno microcontroller and the power module 14 via wires.

[0052] The microcontroller sends control signals to the indicator light module 4 based on the system's operating status, such as the preparation of cold and hot water, and whether water is being dispensed. This causes the indicator light to light up, turn off, or flash, providing intuitive visual feedback to the user and informing them of the water dispenser's current operating status. This makes it easy for the user to understand at a glance, reduces operational errors, and greatly improves the convenience of human-computer interaction.

[0053] The specific embodiments of this utility model have been described in detail above, but they are merely examples, and this utility model is not equivalent to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model should be covered within the scope of this utility model.
