Description

Technical Field

[0001] This invention belongs to the field of household equipment technology, specifically relating to an anti-splash water-saving device, method, and storage medium for an intelligent water dispenser. Background Technology

[0002] Water dispensers are commonly used drinking water devices in homes, offices, schools, and other places. However, the problem of water splashing during the dispensing process has been a long-standing and significant issue. Traditional water dispensers have fixed spout positions and limited water flow control. In addition, users often place containers at slightly off-center, causing water to splash when it hits the inner wall or surface of the container. This not only wastes water resources but also makes the dispensing area damp, increasing the risk of slipping. If hot water is being dispensed, the splashing water can even cause scalding, posing a serious safety hazard.

[0003] Existing improvement solutions mostly focus on optimizing the nozzle shape or reducing the water flow velocity, but they do not solve the core problem: when the container is misaligned, of different sizes, or the liquid level rises, changes in the relative position of the water flow and the container will still cause splashing. The tolerance for container placement errors is extremely low, requiring users to repeatedly adjust the container position in actual use, which is cumbersome. In addition, existing equipment lacks real-time linkage control of container water level and flow rate, making it difficult to dynamically adjust the water flow rate according to the container capacity, resulting in the water flow impact before the container is full still easily causing splashing. Summary of the Invention

[0004] To address the shortcomings of existing water dispensers that focus on optimizing the spout shape or reducing water flow speed, splashing still occurs when the container is misaligned, of different sizes, or the liquid level rises, due to changes in the relative position of the water flow and the container. Furthermore, these devices have a very low tolerance for container placement errors, requiring users to repeatedly adjust the container position, resulting in cumbersome operation. This invention provides an anti-splash water-saving device, method, and storage medium for an intelligent water dispenser to solve the aforementioned technical problems.

[0005] In a first aspect, the present invention provides a splash-proof and water-saving device for an intelligent water dispenser, comprising: The water outlet assembly includes a water outlet nozzle and a mounting bracket that can rotate, lift and extend.

The infrared sensor array is used to acquire information about the position, size, and shape of the water intake container and feeds this information back to the microprocessor. The microprocessor controls the actuator to dynamically adjust the angle, height, and horizontal position of the water outlet based on the information from the infrared sensor array. The flow sensor and the container water level detector are both connected to the microprocessor, which adjusts the water flow rate of the outlet via a flow control valve based on the information from these sensors. The splash guard is controlled to open and close by the microprocessor.

[0008] Further improvements to this technical solution include the following: the horizontal telescopic structure of the L2 segment horizontal telescopic arm includes: Two linear slide rails are arranged in parallel inside the rotating base of section L1; The sliding block is fixedly connected to the nut in the screw drive mechanism. The horizontal telescopic arm of section L2 is fixed to the sliding block by bolts. The sliding block is slidably connected to the linear slide rail. In the lead screw transmission mechanism, one end of the lead screw that is threaded with the nut is connected to a second stepper motor via a coupling.

[0009] Further improvements to this technical solution include: the lifting cylinder for the L3 section lifting rod includes: Cylinder mounting bracket fixed at the end of the L2 section horizontal telescopic boom; The lifting cylinder body is fixed to the cylinder mounting base, and the top of the piston rod inside the lifting cylinder body is connected to the L3 section lifting rod through a flange. The guide shaft that runs through the L3 section lifting rod is clearance-fitted with the guide sleeve at the end of the L2 section horizontal telescopic arm.

[0010] Secondly, the present invention provides a splash-proof water-saving method for an intelligent water dispenser, applicable to the splash-proof water-saving device of any of the above-mentioned intelligent water dispensers, the method comprising: S1. Real-time acquisition of the three-dimensional coordinates (x, y, z), diameter D, and water level of the water intake container via an infrared sensor array. And transmit it to the microprocessor; S2. The microprocessor receives the three-dimensional coordinates (x, y, z), diameter D, and water level of the water intake container. The target pose of the water nozzle is calculated, including the horizontal deflection angle. Horizontal expansion / contraction L and vertical height ; S3. Control the actuator to drive the L1 section rotating base, the L2 section horizontal telescopic arm and the L3 section lifting rod so that the distance between the end of the water outlet and the container opening is less than or equal to the preset distance. The microprocessor controls the opening of the splash guard and initiates water flow through the flow control valve; Based on the real-time water level h of the water intake container fed back by the container water level detector, the flow rate of the water outlet is adjusted according to the pre-stored piecewise function; and when the real-time water level h of the water intake container is greater than or equal to the preset maximum water level, the flow control valve is closed, and the anti-splash cover is closed after a preset delay.

[0011] Further improvements to this technical solution include step S2, which includes: Horizontal deflection angle The calculation formula is: ; The formula for calculating the horizontal expansion / contraction L is: ; The formula for calculating the vertical height H is: ;in, This is a preset safe distance.

[0012] Further improvements to this technical solution include step S3, which includes: The microprocessor calculates the horizontal deflection angle. The first step motor is controlled by a rotation PWM signal to drive the L1 section rotating base to rotate, causing the water outlet to rotate to the target angle. The duty cycle of the rotation PWM signal is... The calculation formula is: ; in, The target rotational speed corresponds to the horizontal deflection angle. rotational rate; This is the maximum rotational speed of the first stepper motor; Based on the calculated horizontal extension amount L, the microprocessor controls the second stepper motor to drive the lead screw transmission mechanism via an extension PWM signal, causing the L2 segment of the horizontal telescopic arm to extend or retract to the target position.

[0013] Further improvements to this technical solution include adjusting the flow rate of the water outlet according to a pre-stored piecewise function, the method of which includes: when At that time, the flow rate of the water outlet , among which, The preset first water level threshold, The initial flow velocity; when At that time, the flow rate of the water outlet ,in, The flow rate decreases linearly as the water level rises, with the preset second water level threshold as the water level increases. when At that time, the flow rate of the water outlet ,in, This is the minimum flow rate, used to ensure a smooth water flow without splashing.

[0014] Thirdly, the present invention provides a computer storage medium storing instructions which, when executed, perform the methods described in the above aspects.

[0015] The beneficial effects of this invention are as follows: Employing a three-section robotic arm structure (L1 rotating base, L2 horizontal telescopic arm, and L3 lifting rod), combined with precise positioning via an infrared sensor array, the system dynamically adjusts the horizontal deflection angle, extension amount, and vertical height of the water outlet according to the container's position and size. This ensures the relative position of the water outlet to the container opening is always optimal (distance from the end of the outlet to the container opening ≤ a preset safe distance). Combined with the physical barrier of a transparent splash guard, this double protection effectively prevents water splashing caused by water flow impact, completely resolving the splashing problem caused by the fixed position and low fault tolerance of traditional equipment, and keeping the water intake area dry and clean.

[0016] By linking the flow sensor and the container water level detector in real time, the outflow rate is dynamically adjusted using a piecewise function: at low water levels, water is injected efficiently at the initial flow rate; at medium water levels, the flow rate is linearly reduced to avoid impact; at high water levels, the flow rate is smoothly terminated at the minimum flow rate until the preset maximum water level is reached and the system automatically shuts off. This precise control not only reduces water waste caused by splashing but also avoids excessive water intake.

[0017] The entire process is intelligent, eliminating the need for manual container adjustment. The infrared sensor array has a high tolerance for container placement errors, significantly reducing the difficulty of operation. The system automatically adapts flow rate parameters to containers of different materials (plastic, glass, etc.) and diameters. When dispensing hot water, a splash guard and a low-flow-rate termination design effectively prevent scalding risks; it also eliminates the risk of slippery surfaces, enhancing safety.
