DETAILED DESCRIPTION

The resistor strip 30 is connected to the resistor 31, and an insulator 34 is installed in the middle. The conductive metal strip 29 is installed above the groove on the right side of the frame 33. The pressure-sensitive conductive strip 28 is located above the conductive metal strip 29. In the absence of external force, the conductive metal strip 29 is separated from the resistor strip 30. When the pressure-sensitive conductive strip 28 is subjected to force, it will simultaneously contact the conductive metal strip and the resistor strip to connect the resistor strip to the circuit.

[0037] There are four voltage-variable resistor strip devices, which are arranged in a cross shape with the center of the drain tray 25 as the center.

[0038] Combination Figure 4-Figure 11As shown, a heating mechanism is also connected to the water tank 1, and the heating mechanism includes a heating shell 12, a heating body assembly plate 22 is arranged in the heating shell, and the heating body assembly plate 22 is connected to the circuit board 14 through the heating tube wire 16, the top of the heating shell 12 is connected to the water nozzle 7 through the upper water outlet pipe 11, and the lower part is connected to the water pump 20 through the rubber water pipe 18, and the water pump 20 is connected to the water intake device; the water pump is connected to the circuit board through the water pump wire, and the water is transported from the water tank 1 to the heating shell 12 through the water intake device 21 through itself, and the water is heated by the internal heating body 23, and flows out of the water nozzle 7 through the upper water outlet pipe; the pressing knob 6 is connected to the circuit board 14 through the pressing knob wire 13, and the action of pressing the knob is transmitted to the circuit board in real time, the detection assembly is connected to the circuit board through the assembly wire 15, and the collected information of the detection assembly is transmitted to the circuit board, and a second wire 32 is connected between the conductive metal strip and the resistor strip, and the second wire 32 is connected to the assembly wire 15 through the first wire 26.

[0039] A push knob cover 4 is provided at the top of the water dispenser body 2, and a push knob 6 is provided on the push knob cover 4, and the push knob 6 controls the opening and closing of the water spout 7. A water receiving tank 10 is also provided on the placement table, and the water receiving tank 10 controls the ejection of the water tank through the water tank ejector 5. A power cord 3 for supplying power to the entire device is also connected to the water dispenser body.

[0040] Combination Figure 1-Figure 15 When the water cup 27 is placed on the drain tray 25, the bottom of the cup contacts the pressure-sensitive conductive strip 28. The contact portion will press the pressure-sensitive conductive strip 28 to form a conductive area at the contact portion. The conductive area formed by the pressure-sensitive conductive strip 28 will connect the resistor strip 30 and the conductive metal strip 29. The pressure-sensitive conductive strip is a resistance-free conductor. When the conductive area is formed, the access position of the resistor strip 30 will be changed, thereby changing the resistance, and then measuring the position of the conductive area from the center point O. Based on the principle of determining a circle by three points, after the cup body is placed in, the pressure-variable resistor strip device installed on the drain tray will measure the information of four position points, thereby more accurately determining the diameter of the cup body.

[0041] The resistor 31 is used to adjust the resistance value of the entire resistor bar 30 to widen the applicable voltage. The farther the short-circuit distance of the resistor bar 30 is from point O, the lower the resistance value is, thereby determining the position distance.

[0042] A leak preventer 35 is installed inside the water tank to prevent water from leaking out when receiving water. After the leak preventer 35 is placed, it contacts with the water intake device, conducts, and water flows out.

[0043] The steps for using the automatic water dispenser are as follows:

[0044] When using a cup for the first time, you need to enter the empty cup information. First, place it on the detection assembly, rotate the push button to the non-temperature selection area, and press for three seconds. At this time, the detection assembly measures the weight of the empty cup, and starts to add water after five seconds. When the water level in the cup is full, short-press the push button. At this time, the water cup weight and the measured water volume information are entered; when the cup is used for water next time, it is placed on the detection assembly to automatically detect the water cup information, and the water dispenser automatically dispenses water according to the temperature on the push knob. When the water quality in the cup reaches the quality when the information was entered, it automatically stops discharging water, and the water discharging is completed;

[0045] When the cup placed is not a registered cup, the water dispenser cannot automatically dispense water. You can press the push knob to dispense water, and release the push knob to stop dispensing water.

[0046] The automatic water dispenser for cup placement mainly realizes automatic water dispensing when a cup is placed, and does not require a button to dispense water. The weight sensor is used to determine the weight of the cup and the amount of water in the cup. The position of the bottom of the cup is converted into coordinates by pressing the resistor bar to determine the area of ​​the bottom of the cup. The resistor coordinate recognition device pre-determines the pre-set cup number, and automatically dispenses water according to the cup number. The weight detection device detects the amount of water, and stops when the amount is reached according to the pre-set amount, creating a water dispenser that is like a hands-off shopkeeper. Using a weight sensor, the water level in the cup is determined by the increase in weight as the amount of water in the cup increases, and quantitative water can also be dispensed. Using a pressure-sensitive resistor bar device, when the cup body is placed on the water collection and draining tray, the cup body presses the pressure-sensitive conductive strip above the resistor bar, and a coordinate system relative to the center is formed according to the resistance value. After the cup bottom is placed, it will press the pressure-sensitive resistor bar at the same time. The principle of determining a circle through three points is used. Four strips are set at the bottom for more accurate identification even if the cup body is not placed in the water collection center. The main principle is that when the cup is placed on the drain tray, the bottom of the cup will contact the pressure-sensitive conductive strip, and the contact area will be pressed by the pressure-sensitive conductive strip to form a conductive area C at the contact area, which will connect the resistor strip to the conductive metal strip. The pressure-sensitive conductive strip is a resistance-free conductor. When the conductive area is formed, it will change the position where the pressure-sensitive resistor strip is connected to the resistor, thereby changing the resistance, and then measuring the position of C from the center point O. The principle of determining a circle by three points, after the cup body is placed, the pressure-sensitive resistor strip device installed on the drain tray will measure the information of four position points, so as to more accurately determine the diameter of the cup body. The resistor is used to adjust the resistance value of the entire resistor strip to broaden the applicable voltage. The farther the short-circuit distance of the resistor strip is from point O, the lower the resistance value, and the closer the position distance is determined.

[0047] When using a cup for the first time, you need to enter the empty cup information. First, place it on the detection assembly, rotate the push knob to the non-temperature selection area, and press and hold for three seconds. The detection assembly will measure the mass of the empty cup and start filling water after five seconds. When the water level in the cup is full, short-press the push button. At this time, the cup mass is measured and the water level information is entered. The next time the cup is used to take water, it will be placed on the detection assembly to automatically detect the cup body information. The water dispenser will automatically dispense water according to the temperature on the push knob. When the quality of the water in the cup reaches the quality when the information was entered, it will automatically stop discharging water and the water discharging is completed. If the placed cup is a non-entered cup, the water dispenser cannot automatically dispense water. You can also dispense water by pressing the push knob. Release the push knob to stop immediately.

[0048] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
