The water storage tank 16 is made of stainless steel and is embedded inside the housing 1. Its top edge is fixed to the inner wall of the housing 1 by welding, and its four bottom corners are in contact with the bottom plate of the housing 1 through rubber pads, which play a role in buffering and shock absorption.
[0027] A fixing rod 13 is provided on one side of the water storage tank 16. The fixing rod 13 is a cylindrical stainless steel rod, and its two ends are welded to the outer wall of the water storage tank 16 through T-shaped washers to ensure its stability. Several connecting rods 14 are provided on the outer wall of the fixing rod 13. A liquid level sensor 15 is sleeved on the outer wall of the connecting rod 14. Six connecting rods 14 are welded at equal intervals in the vertical direction on the outer wall of the fixing rod 13. The connecting rods 14 extend horizontally outward, and an annular groove is processed at their ends. The liquid level sensor 15 is sleeved on the outer wall of the connecting rod 14 through the groove, and the sensor's sensing probe faces the inside of the water storage tank 16.
[0028] The six liquid level sensors 15 correspond to the 10%, 30%, 50%, 70%, 90%, and 100% liquid level heights of the water storage tank 16, respectively. The six liquid level sensors are arranged in a stepped manner within the water storage tank 16 to monitor the water level at different heights.
[0029] A controller 9 is installed at the bottom of the fixing rod 13. The controller 9 is connected to the water storage tank 16 by bolts. The controller 9 adopts a PLC control module and is fixed to the bottom outer wall of the water storage tank 16 below the fixing rod 13 by bolts.

[0032] When the left button of switch 4 is pressed, the solenoid valve of the cold water pipe opens, and cold water is output from outlet pipe 5; when the right button is pressed, the solenoid valve of the hot water pipe starts, and hot water is output from outlet pipe 5.
[0033] Specifically, a slot is provided on one side of the shell 1, and a square slot is provided in the upper middle position of the front of the shell 1. The top two outer walls of the slot are fixedly connected to one end of the water outlet pipe 5 by welding. Water outlet pipes 5 are provided on both top two outer walls of the slot. The water inlet end of the water outlet pipe 5 is connected to the hot water tank and cold water tank inside the shell 1, respectively.
[0034] Specifically, a water storage tank 6 is slidably connected to the bottom outer wall of the slot. The water storage tank 6 is used at least to collect excess water in the outlet pipe 5. Two parallel slide rails are provided on the bottom outer wall of the slot. The slide rails extend along the length of the slot. A slider matching the slide rail is welded to the bottom outer wall of the water storage tank 6. The water storage tank 6 achieves slid connection with the bottom outer wall of the slot through the sliding cooperation of the slider and the slide rail. Limiting blocks are provided at both ends of the slide rail to prevent the water storage tank 6 from detaching from the slot during sliding.
[0035] When there is excess water discharged from the outlet pipe 5, the water will drip into the water storage tank 6. When the water in the water storage tank 6 has collected a certain amount, the operator can pull the handle at the front end of the water storage tank 6 to pull it out of the slot along the slide rail so as to pour out the water. Then, the water storage tank 6 is pushed back to its original position along the slide rail. At this time, the slider will move smoothly along the slide rail until the water storage tank 6 is completely embedded in the bottom of the slot.

When the cover plate 8 is closed, its edge fits against the edge of the storage box. The middle part of the cover plate 8 is made of transparent acrylic material, and the operator can observe the storage of items inside the storage box through the transparent plate.
[0039] Working steps: 1. Power on the equipment and observe whether the operation light 3 is lit normally. If it is lit, it means that the equipment has been successfully started and entered the running state.
[0040] 2. Start the water pump 10, and the liquid flows into the water storage tank 16 through the water pipe and the outlet;
[0041] Third, the water level in the water storage tank 16 is monitored by the information fed back by the liquid level sensor 15 to ensure that the water level is within a reasonable range. If the water level is too low or too high, the controller 9 can make corresponding adjustments in a timely manner.
[0042] 4. Press the corresponding switch 4 to get drinking water from the corresponding water outlet 5. The spilled water will flow into the water storage tank 6. When it reaches a certain depth, the water storage tank 6 can be manually pulled out.
