[0002] Water dispensers are common devices in daily life, and their main function is to provide users with convenient access to drinking water.

[0003] To facilitate water dispensing control, many smart water dispensers are now available, offering both manual and automatic switching based on water level detection to enhance convenience. Automatic switching based on water level detection increases automation and prevents overflow during manual dispensing. Current technology typically uses water level detection at the spout and along the rim of the cup to determine when to stop dispensing. However, due to variations in cup diameter and thickness, the upper limit of the cup's height is difficult to accurately detect, leading to potential errors in water level assessment.

[0004] Therefore, it is necessary to improve the overflow prevention system of water dispensers to enhance the accuracy of overflow detection and related controls. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] This embodiment provides an anti-overflow drinking water device based on an ultrasonic module. (See reference...) Figures 1-2 The water dispensing device is controlled by a solenoid valve and includes a water dispenser body 105, a first ultrasonic sensor 101, multiple second ultrasonic sensors 102, and a start / stop control component.

[0035] The first ultrasonic sensor 101 is slidably disposed next to the water outlet 103 of the water dispenser body 105, and the detection direction of the detection end of the first ultrasonic sensor 101 is vertically downward and towards the water cup placement area.

[0036] Multiple second ultrasonic sensors 102 are respectively disposed at different heights of the water dispenser body 105, and the detection direction of the detection end of the second ultrasonic sensor 102 is horizontal and facing the water cup placement area.

[0037] The first ultrasonic sensor 101 and the plurality of second ultrasonic sensors 102 are respectively connected to the start-stop control component.

[0038] In this embodiment, a horizontal groove 104 is provided next to the water outlet 103 of the water dispenser body 105, and the first ultrasonic sensor 101 is slidably disposed in the groove 104.

[0039] Specifically, the second ultrasonic sensor 102 is respectively disposed on the front side of the water dispenser body 105.

[0040] Furthermore, the plurality of second ultrasonic sensors 102 are distributed at equal intervals.

[0041] This embodiment uses a first ultrasonic sensor 101 to detect the water level, and the position of the first ultrasonic sensor 101 can be adjusted horizontally according to different cup diameters. It also uses multiple second ultrasonic sensors 102 at different heights to detect the height of the cup. The system can record the height set for each second ultrasonic sensor 102. Finally, using the highest position detected by the second ultrasonic sensor 102 as a reference, if the water level reaches a preset threshold from this highest position during water level detection, the solenoid valve needs to be closed for adjustment. This embodiment allows for more flexible and reliable detection of cups of different shapes and sizes, overcoming the difficulty in detecting the edge of the cup.

[0042] As a preferred embodiment, the start-stop control component includes a main control module, a switch detection circuit, and a switch control circuit;

[0043] The output terminal of the first ultrasonic sensor 101, the output terminals of the plurality of second ultrasonic sensors 102, the output terminal of the switch detection circuit, and the input terminal of the switch control circuit are respectively connected to the main control module;

[0044] The input terminal of the switch detection circuit and the output terminal of the switch control circuit are connected to the solenoid valve.

[0045] See Figure 3 The switch detection circuit includes a voltage detector and multiple resistors;

[0046] One end of the first resistor R1 is connected to the output terminal of the solenoid valve, the other end of the first resistor R1 is connected to the positive input terminal of the voltage detector, and one end of the second resistor R2 is connected to the negative input terminal of the voltage detector. The output terminal of the voltage detector is connected to the main control module.

[0047] See Figure 4 The switch control circuit includes a transistor, multiple resistors, and a diode D1;

[0048] One end of the third resistor R3 is connected to the main control module, and the other end of the third resistor R3 is connected to one end of the fourth resistor R4 and the base of the first transistor Q1. The emitter of the first transistor Q1 and the other end of the fourth resistor R4 are grounded. The collector of the first transistor Q1 is connected to the anode of the diode D1, and the cathode of the diode D1 is connected to a DC source. The solenoid valve is connected across the two ends of the diode D1.

[0049] When the highest position detected by the second ultrasonic sensor 102 of the water cup is used as a reference, and the first ultrasonic sensor 101 detects that the water level distance from this highest position reaches a preset threshold, requiring adjustment to close the solenoid valve, the on / off state of the solenoid valve is first detected by the switch detection circuit. The detection result is output by the voltage detector. Because there is current in this branch when the solenoid valve is on, it can be detected by the voltage change of the second resistor R2. The first resistor R1 can be used as a safety voltage divider resistor, and the second resistor R2 serves as a detection resistor. When the solenoid valve needs to be closed and it is detected that it is not closed, there is no need to wait for the user to press a button; instead, the main control module directly sends a command to the switch control circuit to execute the operation of closing the solenoid valve. The main control module controls the opening and closing of the solenoid valve by controlling the on / off state of the first transistor Q1.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
