[0028] The purpose of this utility model is to prevent the heater from burning out due to water tank leakage, which in turn leads to electrical leakage.

[0029] Therefore, this application provides a safe intelligent direct drinking water machine, including: a shell, a water tank 100, a water receiving tray 300, a water leakage sensor 200, and a power failure module.

[0030] The housing 210 serves as the outer shell of the entire intelligent water dispenser, housing the water tank 100, water tray 300, leakage sensor 200, and power-off module. Of course, in addition to the water tank 100, water tray 300, leakage sensor 200, and power-off module, the entire intelligent water dispenser also includes other modules and mechanisms for realizing the functions of the intelligent water dispenser, which will be described in detail here.

[0031] Regarding the shape of the shell, the application specifies that it includes an upper shell portion 101, a connecting portion 102, and a lower shell portion 103. The upper shell portion 101 is connected to the lower shell portion 103 via the connecting portion 102, and a water intake area is provided between the upper shell portion 101 and the lower shell portion 103. The entire shell is shaped like a three-dimensional column with a central notch.

[0032] The water intake area primarily provides water for users, and a water outlet 110 is installed at the upper part of the water intake area. The water outlet 110 is connected to the water dispensing mechanism, allowing users to obtain the drinking water they need through the water outlet 110. The water outlet 110 is connected to the upper shell 101.

[0033] To allow users to collect drinking water from the spout 110 by placing their cup on it, a water receiving platform 120 is provided at the bottom of the water dispensing area. The water receiving platform 120 is connected to the lower housing 103. Located below the spout 110, the water receiving platform 120 allows users to collect drinking water from the spout 110 by placing their cup on the water receiving platform 120.

[0034] In some further specific embodiments, the water receiving platform 120 includes a cup holder and a drain trough, with the opening of the drain trough facing the water outlet 110. The cup holder covers the opening and has an array of strip-shaped holes. The cup holder supports the user's cup, allowing the user to place the cup on it when needing water. The drain trough prevents spilled water from impacting the environment. When water overflows from the cup, it flows into the drain trough through the array of strip-shaped holes on the cup holder. The drain trough is connected to a specific drain pipe, which drains the water from the drain trough to a specific location, thus preventing spilled water from impacting the environment.

[0035] The water tank 100 is located inside the lower shell 103, and a heater is installed on the water tank 100. The function of the heater is to heat the water inside the water tank 100, thereby enabling the intelligent direct drinking water to have a heating function.

[0036] The water receiving tray 300 is located below the water tank 100. The bottom of the water receiving tray 300 is not horizontal. The leakage sensor 200 is installed at the lowest point of the bottom of the water receiving tray 300.

[0037] The power-off module is connected to the water leakage sensor 200 and the heater respectively. The power-off module is used to disconnect the power supply to the heater according to the triggering of the water leakage sensor 200.

[0038] The receiving tray is used to receive water leaking from the water tank 100, preventing it from flowing outside the casing. To detect leaks in the water tank 100 promptly, a leak sensor 200 is installed in the receiving tray 300. The bottom of the receiving tray 300 is non-planar, and the leak sensor 200 is located at the lowest point of the bottom of the receiving tray 300. When the water tank 100 leaks, the water enters the receiving tray 300 due to gravity. Because the bottom of the receiving tray 300 is non-planar, the leaking water flows towards the leak sensor 200 under the influence of gravity.

[0039] When the water leakage sensor 200 detects a leak, it transmits a trigger signal to the power-off module. The power-off module disconnects the power supply to the heater based on the trigger signal from the water leakage sensor 200. This keeps the heater in a power-off state, preventing it from burning out due to water leakage from the water tank 100 and improving the overall safety of the smart direct drinking water system.

[0040] In some further specific embodiments, the power-off module includes: an energy storage battery, a power supply node VCC, a ground node GND, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a first transistor Q1, a second transistor Q2, an optocoupler U1, a first diode D1, and a relay K1.

[0041] The function of the energy storage battery is to provide the power-off module with independent power, preventing it from being affected by external power outages. In some further specific embodiments, the energy storage battery is a lithium battery.

[0042] The positive terminal of the energy storage battery is connected to the power supply node VCC, and the negative terminal of the energy storage battery is connected to the ground node GND; one end of the first resistor R1 is connected to one end of the second resistor R2 and one end of the water leakage sensor 200, and the other end of the second resistor R2 is connected to the base of the first transistor Q1.

[0043] The other end of the first resistor R1 is connected to one end of the third resistor R3, the collector of the optocoupler U1, and one end of the sixth resistor R6, respectively. The other end of the third resistor R3 is connected to the anode of the optocoupler U1. The cathode of the optocoupler U1 is connected to the collector of the first transistor Q1. The emitter of the optocoupler U1 is connected to one end of the fourth resistor R4. The other end of the fourth resistor R4 is connected to one end of the fifth resistor R5 and the base of the second transistor Q2, respectively. The collector of the second transistor Q2 is connected to the anode of the first diode D1 and one end of the coil of the relay K1, respectively. The other end of the coil of the relay K1 is connected to the cathode of the first diode D1 and the other end of the sixth resistor R6, respectively.

[0044] The moving end of the switch side of the relay K1 is connected to the external power supply terminal, the normally open end of the switch side of the relay K1 is connected to the heater, and the normally closed end of the switch side of the relay K1 is unconnected; the other end of the water leakage sensor 200, the emitter of the first transistor Q1, the emitter of the second transistor Q2, and the other end of the fifth resistor R5 are respectively connected to the ground node GND.

[0045] In some further specific embodiments, the water leakage sensor 200 includes: a housing 210, a positive electrode pin 250, and a negative electrode plate 230; the housing 210 has an internal cavity 220, the negative electrode plate 230 is installed at the bottom of the cavity 220, the positive electrode pin 250 is inserted into the cavity 220 from the outside of the housing 210 from top to bottom, and the bottom side wall of the cavity 220 has a water inlet 240; the positive electrode pin 250 is connected to one end of the second resistor R2 and one end of the first resistor R1 through a wire; the negative electrode plate 230 is connected to the ground node GND through a wire.

[0046] In practical operation, leaking water flows into the leak sensor 200 through the water receiving tray 300 and enters the receiving cavity 220 through the water inlet 240. As the leakage increases, the amount of water in the receiving cavity 220 will also increase, raising the water level. When the water level in the receiving cavity 220 rises to cover the positive electrode pin 250, the voltage at the base of the first transistor Q1 will be pulled low, causing Q1 to turn off. The optocoupler U1 will also turn off, thus turning off the second transistor Q2. Since the second transistor Q2 is off, the relay K1 will be de-energized, disconnecting the external power supply from the heater. This achieves the function of de-energizing the heater.

[0047] This invention utilizes a water receiving tray 300 to receive leaked water from the water tank 100, and guides the leaked water through the non-planar bottom of the tray 300, directing it to the leak sensor 200. The leak sensor 200's response alerts a power-off module, which then promptly cuts off power to the heater. This prevents the heater from burning out due to leaks in the water tank 100, thus improving the overall safety of the intelligent direct drinking water system.

[0048] To facilitate water collection, in some further embodiments, a handrail 130 is provided on the front side wall of the lower shell 103. Users can use the handrail 130 for support to collect water conveniently.

[0049] To facilitate the movement of the smart drinking water machine, in some further embodiments, the bottom of the lower shell 103 is provided with casters. These casters are omnidirectional wheels.

[0050] In some further specific embodiments, the upper shell 101, the connecting part 102, and the lower shell 103 are all stainless steel components. The upper shell 101 is provided with a touch screen 140, which is used to control the water outlet 110 by triggering.

Rather, it should be considered as effectively covering the intended scope of this application by referring to the appended claims and taking into account the broad possible interpretations of these claims provided by the prior art.
