Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a multifunctional intelligent water shut-off direct drinking water machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0005] The solution to the technical problem of this utility model is:
[0006] A multi-functional intelligent water shut-off direct drinking water machine with leakage prevention, comprising:
[0007] The housing has an interconnected mounting cavity and a water leakage and storage cavity. The water leakage and storage cavity is located below the mounting cavity. The water leakage and storage cavity is equipped with two water leakage level sensors, which are arranged vertically. The two water leakage level sensors are respectively set as a high water level sensor and a low water level sensor.
[0008] The water dispenser has a water circuit with a raw water inlet pipe and a leak switch. The leak switch is used to control the opening and closing of the raw water inlet pipe.

The detection part is connected to the lowest end of the funnel part, and the water leakage level sensor is installed in the detection part, which is located below the funnel part.
[0010] As a further improvement to the above technical solution, it also includes a leakage pump and a leakage outlet pipe; the leakage pump is connected to the detection unit; the leakage pump is configured to: when the high water level sensor sends a signal, the leakage pump starts and pumps out the water from the leakage storage chamber; when the low water level sensor sends a signal, the leakage pump stops; the leakage outlet pipe is connected to the leakage pump.
[0011] As a further improvement to the above technical solution, the outer casing is equipped with a drip tray.
[0012] As a further improvement to the above technical solution, the drip tray is connected to a drip pipe, and the end of the drip pipe away from the drip tray is connected to the leakage and water storage cavity.

[0027] Traditional water purifiers are prone to damage to internal components such as water tanks and pipes after long-term use due to factors such as pipe aging, water corrosion, or external impact, which can lead to water leakage problems.
[0028] When the leakage is too severe, a large amount of outside water will flow into the water dispenser, leading to increased water costs; and it will also be accompanied by water overflow, causing water to spill onto the floor around the water dispenser, affecting the aesthetics and cleanliness of the room.
[0029] This solution was designed to address the aforementioned technical problems.
[0030] Reference Figure 1 and Figure 2 A multifunctional smart water-stopping direct drinking water machine with leakage protection includes a shell 100, a water circuit 300, and a control module.
[0031] The outer casing 100 is provided with a water leakage and storage cavity 120 and an installation cavity, which are connected to each other, and the water leakage and storage cavity 120 is located below the installation cavity.
[0032] The outer casing 100 is equipped with a drip tray 200, which is used to collect water dripping from the spout.
[0033] The drip tray 200 is connected to a drip pipe 210, and the end of the drip pipe 210 away from the drip tray 200 is connected to the water storage chamber 120. This allows water in the drip tray 200 to flow into the water storage chamber 120 through the drip pipe 210, so that water leaking from the water outlet and water leaking from the internal components of the water dispenser can flow into the water storage chamber 120.
[0034] Specifically, in this embodiment, the drip tray 200 is detachably connected to the outer casing 100. The drip tray 200 is set to be detachably connected to the outer casing 100 so that the drip tray 200 can be removed for cleaning, thereby avoiding the inconvenience of cleaning caused by the fixed setting of the drip tray 200.
[0035] Specifically, in this embodiment, the lower end of the drip tray 200 is fixedly provided with a plugging protrusion 220, and the outer shell 100 is provided with a plugging groove 110. The plugging protrusion 220 and the plugging groove 110 are provided in a one-to-one correspondence, and the plugging protrusion 220 and the plugging groove 110 are plugged and connected.
[0036] Specifically, in this embodiment, the insertion groove 110 and the insertion protrusion 220 are interference-fitted. The interference fit between the insertion protrusion 220 and the insertion groove 110 makes it less likely for the drip tray 200 to detach from the outer casing 100 due to accident.
[0037] Specifically, in this embodiment, a pipe interface 230 is fixed at the lower end of the drip tray 200, and the pipe interface 230 is used to connect to the drip pipe 210.
[0038] Specifically, in this embodiment, a sealing groove 231 is provided on the outer periphery of the pipe interface 230, and an O-ring 232 is installed in the sealing groove 231. By providing the sealing groove 231 and the sealing ring 232, the sealing performance between the pipe interface 230 and the drip pipe 210 can be enhanced.
[0039] Specifically, in this embodiment, the number of sealing grooves 231 and sealing rings 232 are each set to two, and the sealing grooves 231 and sealing rings 232 are set in a one-to-one correspondence.
[0040] The water storage chamber 120 is equipped with a water level sensor. Specifically, there are two water level sensors, which are arranged vertically and are both connected to the control module.
[0041] The upper water level sensor is set as a high water level sensor 1211, and the lower water level sensor is set as a low water level sensor 1212.
[0042] Specifically, in this embodiment, the leak-proof water storage cavity 120 includes a detection unit 122 and a funnel-shaped unit 123. The funnel-shaped unit 123 is a funnel-shaped structure, and the detection unit 122 is connected to the lowermost end of the funnel-shaped unit 123. The detection unit 122 extends downward, and all leak-proof water level sensors are installed inside the detection unit 122.
[0043] Both the high water level sensor 1211 and the low water level sensor 1212 are installed in the detection unit 122. The water level in the detection unit 122 can be monitored in real time by the high water level sensor 1211 and the low water level sensor 1212, so as to determine whether the water dispenser is leaking. Furthermore, the severity of the water leak can be determined by the time difference between the signals emitted by the high water level sensor and the low water level sensor 1212.
[0044] Specifically, in this embodiment, a one-way valve is installed at the end of the water leakage pipe 240 to prevent waste liquid from flowing back into the waste liquid pipe and causing contamination inside the water dispenser.
[0045] When a leak occurs, the water leaking from the water dispenser will fall directly into the leak storage chamber 120. If the spout leaks, the leaked water will flow through the drip tray 200 and the drip pipe 210 to collect in the leak storage chamber 120. The funnel part 123 of the leak storage chamber 120 guides the water flow to the detection part 122.
[0046] The water circuit 300 of the water dispenser is a conventional direct drinking water machine water circuit 300 (the water circuit 300 of the water dispenser is simply represented by a rectangle in the figure). It includes a hot water storage tank, a hot water pump, a hot water outlet, a hot water pipeline, a heat exchanger, a warm water storage tank, a warm water pump, a warm water outlet, a warm water pipeline, a cold water pipeline, a purifier, a waste liquid pipeline, etc. The specific structure of the water circuit 300 of the water dispenser will not be described in detail here.
[0047] The water dispenser water circuit 300 is equipped with a raw water inlet pipe 310, and a water leakage switch 320 is installed at the raw water inlet pipe 310. The water leakage switch 320 is connected to the control module signal and is used to control the opening and closing of the raw water inlet pipe 310.
[0048] To further address the issue of leaking water, in this embodiment, the multifunctional intelligent water-stopping direct drinking water machine also includes a leaking water outflow pipe 240 and a leaking water pump 250.
[0049] The water leakage outlet pipe 240 is connected to the water leakage pump 250. One end of the water leakage outlet pipe 240 is connected to the waste liquid pipe, so that the water flowing out of the water leakage outlet pipe 240 can flow into the waste liquid pipe and finally flow out of the water dispenser from the waste liquid pipe.
[0050] The leakage pump 250 is installed in the detection unit 122. The leakage pump 250 is connected to the control module. When the high water level sensor 1211 sends a signal, the leakage pump 250 starts and pumps out the water in the leakage storage chamber 120. When the low water level sensor 1212 sends a signal, the leakage pump 250 stops.
[0051] The low water level sensor 1212 is the first to detect a rise in water level and issues a warning signal. If the water level continues to rise, it triggers the high water level sensor 1211, which will issue a signal. When the control module detects that the interval between the signal issued by the high water level sensor 1211 and the signal issued by the low water level sensor is less than a set value, the control module determines that there is a serious leak. The leak switch 320 immediately cuts off the raw water inlet pipe 310, thereby preventing raw water from further entering the machine. At the same time, the leak pump 250 is started, driving the water in the leak storage chamber 120 through the leak outlet pipe 240 and into the waste liquid pipe, and finally discharged from the water purifier through the waste liquid pipe. This solution can avoid a significant increase in water costs and can greatly prevent water overflow, thus ensuring the indoor aesthetics and cleanliness.
[0052] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
