[0019] Figure 1 It is the structural principle diagram of the water system of the water dispenser in this case.

[0020] Figure 2 This is the circuit structure schematic diagram of the control mainboard of the water dispenser in this case. DETAILED DESCRIPTION

[0021] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0022] like Figure 1 As shown, a drinking fountain with an ultra-high water level detection function includes a water system 100 and a control mainboard 200 for controlling the operation of various components in the water system 100. The water system 100 includes: a water inlet 1, a water storage pot 2, a water level detection component 3, and a water outlet 4. One input end of the water inlet 1 is connected to the water storage pot 2, and the other input end is connected to the water level detection component 3. The water storage pot 2 is connected to the water outlet 4; the water level detection component 3 includes: a water storage cavity 31, a water storage cavity 31 disposed on the water storage cavity 31. The high water level detection structure and the super-high water level detection structure are provided, wherein the high water level detection structure comprises: a first float 321 that floats up and down with the change of water level, and a high water level detector 322 that is arranged at an upper position of the water storage cavity 31 and is used to detect whether the first float 321 is close to the water storage cavity 31; the super-high water level detection structure comprises: a second float 331 that floats up and down with the change of water level, and a super-high water level detector 332 that is arranged at a position higher than the high water level detector 322 in the water storage cavity 31 and is used to detect whether the second float 331 is close to the water storage cavity 31;

[0023] Among them, Figure 2 As shown, the high water level detector 322 is electrically connected between one input end and one output end of the control mainboard 200 to form a high water level detection circuit 101, and the super-high water level detector 332 is electrically connected between another input end and another output end of the control mainboard 200 to form a super-high water level detection circuit 102. In a specific implementation, the high water level detector 322 and the super-high water level detector 332 can be photoelectric sensors.

[0024] As described above, in this case, a water level detection component 3 is provided in the water system 100, and a water storage cavity 31, a high water level detection structure and an ultra-high water level detection structure are provided in the water level detection component 3, so as to form a dual water level detection structure. The water dispenser can more accurately control the water level in the water storage pot, ensuring that overflow or other safety problems caused by excessively high water levels will not occur when the user takes water or the equipment is in operation. At the same time, the control main board 200 forms a high water level detection circuit 101 with the high water level detector 322 and forms an ultra-high water level detection circuit 102 with the ultra-high water level detector 332, so that the control main board 200 can monitor the on and off states of the high water level detector 322 and the ultra-high water level detector 332 respectively. If it is detected that the high water level detector 322 is triggered, a signal to stop water intake is sent to the control main board 200; if the high water level detector 322 fails, the water level continues to rise and triggers the ultra-high water level detector 332, and the control main board 200 sends a signal to stop water intake, thereby cooperating with the water level detection component 3 to provide double protection against overflow.

[0025] like Figure 1 and Figure 2 As shown, the water inlet solenoid valve 5 is connected between the water level detection component 3 and the water inlet 1, and the control main board 200 is electrically connected to the water inlet solenoid valve 5. In specific implementation, the control main board 200 will control the water inlet solenoid valve 5 to open according to the signal of the water level detection component 3, thereby allowing water to flow from the water inlet 1 into the water storage pot 2. On the contrary, when the water level reaches or exceeds the set water level, the water inlet solenoid valve 5 will be closed to prevent water from overflowing. In this way, through the cooperation of the water level detection component 3 and the control main board 200, the water dispenser can realize automatic water inlet management without manual operation by the user, and through the control method of electrical connection, the switch state of the water inlet solenoid valve 5 can be accurately controlled, which can greatly reduce the safety risks caused by abnormal water level.

[0026] like Figure 1 and Figure 2 As shown, during the specific implementation, the water system 100 also includes: a mineralized filter element assembly 6, a heating assembly 7, and a water pump 8. The water inlet 1 is connected to the input end of the mineralized filter element assembly 6, one output end of the mineralized filter element assembly 6 is connected to the water storage pot 2, and the other output end is connected to the water level detection assembly 3. The water in the water storage pot 2 is pumped to the heating assembly 7 through the water pump 8, and the water outlet end of the heating assembly 7 is connected to the water outlet 4; the control main board 200 is electrically connected to the heating assembly 7 and the water pump 8 respectively.

[0027] A normally open solenoid valve 9 is connected between the water inlet solenoid valve 5 and an input end of the mineralized filter element assembly 6 , and the control mainboard 200 is electrically connected to the normally open solenoid valve 9 .

[0028] As described above, the water in the water dispenser of this case first enters the mineralization filter element assembly 6 from the water inlet 1 and then is output from the mineralization filter element assembly 6 to the water storage pot 2 and the water level detection assembly 3 respectively. Then the water pump 8 pumps the filtered water in the water storage pot 2 to the heating assembly 7, and finally flows out from the water outlet 4, so that minerals and trace elements can be added before heating, and then heated, which helps to dissolve and disperse the minerals, so that the minerals and trace elements in the water are more evenly distributed, and can provide a more even distribution of minerals, which is conducive to improving the mineralization effect. The control mainboard 200 is electrically connected to the heating assembly 7, the water pump 8, and the normally open solenoid valve 9 respectively, so that the control mainboard 200 can be used to control the water level detection assembly 3.

[0029] The centralized control of the heating component 7, the water pump 8, and the normally open electromagnetic valve 9 can be realized, and their working states can be monitored and adjusted. So that the water dispenser can adjust the working states of the heating component 7, the water pump 8, and the normally open electromagnetic valve 9 according to actual needs, avoiding unnecessary energy waste.

[0030] like Figure 1 As shown, in a specific implementation, the heating assembly 7 includes: a heating tube 71, a water inlet NTC 72 arranged at the water inlet end of the heating tube 71, a water outlet NTC 73 arranged at the water outlet end of the heating tube 71, an anti-dry-burning NTC 74 and a temperature control switch 75 arranged on the heating tube 71, and the heating tube 71 is an instant heating tube with a power of 2100W. The input end of the control mainboard 200 is electrically connected to the water inlet NTC 72 and the water outlet NTC 73 respectively, and the output end is electrically connected to the heating tube 71 and the temperature control switch 75.

[0031] As described above, the heating tube 71 of the heating assembly 7 and its water inlet NTC 72 and water outlet NTC 73 and the setting of electrical connection with the control mainboard 200 can monitor the temperature of the water inlet and outlet of the heating tube 71 in real time, so that the control mainboard 200 can adjust the heating power in real time according to the change of water temperature, ensure that the water reaches the set temperature in the shortest time, which is conducive to the precise temperature control of the water dispenser while improving the heating efficiency. The setting of the anti-dry-burning NTC 74 and its temperature control switch 75 is convenient for detecting the temperature inside the heating tube, quickly sensing and triggering the temperature control switch 75 to cut off the power supply, and preventing the heating tube from being damaged due to dry burning, which is conducive to improving the safety and service life of the heating tube. The heating tube 71 is a setting of an instant heating tube with a power of 2100W. Through the high power of 2100W, the heating tube can quickly heat the water to the required temperature in a short time, greatly reducing the time for users to wait for hot water; and through its instant heating design, it will only work when heating is needed, avoiding a long preheating and insulation process, thereby reducing energy waste.

[0032] like Figure 1 and Figure 2As shown, during the specific implementation, a flow meter 91 is provided between the output end of the water storage pot 2 and the water pump 8, and the control mainboard 200 is electrically connected to the flow meter 91 to form a flow detection circuit. In this way, on the one hand, it is convenient to monitor whether there is abnormal flow in the water channel and output flow data to the control mainboard 200, thereby improving the stability and safety of the system. On the other hand, it is convenient to adjust the power of the water pump 9 according to the water flow in the system, so as to ensure that the water dispenser can be used according to actual needs, avoid unnecessary energy waste, and be more environmentally friendly. For example, when the water consumption is small, the control mainboard 200 can control the water pump 9 to reduce the power, avoiding unnecessary high-power operation and energy waste. On the contrary, when the water consumption increases, the control mainboard 200 can control the water pump 9 to increase the power to ensure that the water supply meets the demand; thereby improving the intelligence level and user experience of the water dispenser.

[0033] like Figure 2 As shown, in a specific implementation, the control mainboard 200 is also electrically connected to a boat-shaped switch 10 for controlling the power on and off of the water dispenser, so as to realize the quick on and off operation of the water dispenser. The control mainboard 200 is also electrically connected to a display screen 11 and a control button 12 through a serial port. In this way, the water dispenser controls the power on and off of the water dispenser through the design of the boat-shaped switch 10, which is convenient for users to operate. The setting of the display screen 11 and the control button 12 electrically connected through the serial port can allow users to input instructions, such as setting water temperature and selecting working mode, so as to realize richer user operation and control functions.

[0034] As mentioned above, this case protects a water dispenser with an ultra-high water level detection function. All technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
