[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0031] like Figure 1 as well as Figure 2 As shown, the utility model requests a waste water channel structure, including a three-way component 1. The unique design of the three-way component 1 helps to discharge the internal waste water cleanly before outputting drinking water, ensuring the hygiene of drinking water. Specifically, the three-way component 1 is provided with a first water outlet pipe 101, a second water outlet pipe 102 and a water inlet pipe 103, the first water outlet pipe 101 is located at the bottom, the second water outlet pipe 102 is located at the top, and the water inlet pipe 103 is located on the side; the three-way component 1 is provided with a water chamber 104, which is a chamber formed by internal encirclement. The water chamber 104 is provided with a waste water hole 105, a drinking water hole 106 and a water inlet hole 107, the waste water hole 105 is located at a low position, and the drinking water hole 106 is located at a high position. The waste water hole 105 is connected to the first water outlet pipe 101, the drinking water hole 106 is connected to the second water outlet pipe 102, and the water inlet hole 107 is connected to the water inlet pipe 103.

[0032] It also includes a wastewater pump 2 and a water supply pump 3; the wastewater pump 2 is connected to the first water outlet pipe 101, and is used to pump out the wastewater in the water chamber 104; the water supply pump 3 is connected to the water inlet pipe 103, and is used to pump water into the water chamber 104; it also includes a first delivery pipe 6, one end of the first delivery pipe 6 is connected to the kettle body of the liquid heating device, the other end of the first delivery pipe 6 is connected to the inlet of the water supply pump 3, the outlet of the water supply pump 3 is connected to the second delivery pipe 7, and the second delivery pipe 7 is connected to the water inlet pipe 103; the first water outlet pipe 101 is connected to the third delivery pipe 8, the third delivery pipe 8 is connected to the inlet of the wastewater pump 2, the outlet of the wastewater pump 2 is connected to the fourth delivery pipe 9, the second water outlet pipe 102 is connected to one end of the fifth delivery pipe 10, and the other end of the fifth delivery pipe 10 is connected to the drinking water outlet of the liquid heating device.

[0033] The application principle of the above structure is: when outputting drinking water, it is necessary to drain the wastewater in the water chamber 104 first. At this time, the wastewater discharge pump 2 is started first to work, and the wastewater in the water chamber 104 is discharged through the third delivery pipe 8, the wastewater discharge pump 2, and the fourth delivery pipe 9. The wastewater discharge pump 2 can be set to work for 0.1 to 5 seconds and then disconnected. At this time, it can just drain the wastewater in the water chamber 104 and then stop working; then the water supply pump 3 works, and fresh water is input into the water chamber 104 through the first delivery pipe 6, the water supply pump 3, and the second delivery pipe 7; the water level in the water chamber 104 gradually rises, and when the water chamber 104 is full, it is output for drinking through the drinking hole 106, the second water outlet pipe 102, and the fifth delivery pipe 10.

[0034] In this embodiment, the height of the wastewater hole 105 in the water chamber 104 is set to D1, the height of the drinking water hole 106 in the water chamber 104 is set to D2, and the height of the water inlet hole 107 in the water chamber 104 is set to D3, then D1 ≥ 0, D2>D3>D1; Figure 1 as well as Figure 2 As shown, the wastewater hole 105 is opened on the bottom surface of the inner wall of the water chamber 104, that is, D1=0. This design is conducive to the complete outflow of wastewater in the water chamber 104, and the drinking water hole 106 is located at the top of the inner wall of the water chamber 104, which is also at the highest position of the water chamber 104. It overflows after the water is full, so that the entire water chamber 104 is filled with water. This not only helps to squeeze out the gas entering the water chamber 104 when discharging wastewater (when the wastewater pump 2 starts to discharge wastewater, due to the negative pressure formed inside the water chamber 104, external gas will enter the water chamber 104 through the fifth delivery pipe 10), but also avoids the existence of excess gas space in the water chamber 104, which causes dirt and unsanitary conditions.

[0035] A baffle 4 is provided in the water chamber 104, which divides the water chamber 104 into a first cavity 1041 and a second cavity 1042. The upper end of the baffle 4 is connected to the top of the inner wall of the water chamber 104, and the lower end of the baffle 4 is kept at a distance from the bottom of the inner wall of the water chamber 104 to form a flow port, which allows the first cavity 1041 and the second cavity 1042 to communicate with each other; the water inlet 107 is located on one side of the first cavity 1041 and corresponds to the baffle 4, and the drinking water hole 106 is located at On one side of the second cavity 1042; the central axis of the water inlet 107 is perpendicular to the baffle 4. When the water supply pump 3 is started to supply water, the impact force of the water is very large. At this time, the water enters from the water inlet 107 and first impacts the baffle 4 to change the flow direction, forming a certain vortex phenomenon. The vortexing part of the water and the other part of the water that continues to come in will form a certain impact, which helps to slow down the flow speed of the water, reduce the kinetic energy, reduce the impact force, and have a certain protective effect on the water chamber 104; Figure 1 as well as Figure 2As can be seen, the baffle 4 extends vertically downward, and the lower end of the baffle 4 is connected to a drain plate 5, which is tilted downward toward the second cavity 1042. This design is beneficial for guiding the water downward and toward the second cavity 1042, so that the water fills the bottom of the water chamber 104 and then rises to overflow.

[0036] like Figure 4 As shown, it also includes a frame 11, and the wastewater pump 2 and the water supply pump 3 are respectively fixed on both sides of the inside of the frame 11, which helps to coordinate the weight balance on both sides of the frame 11. A sewage pipe 12 is provided in the middle of the frame 11, and the fourth delivery pipe 9 is connected to the sewage pipe 12; the wastewater is finally discharged through the fourth delivery pipe 9 and the sewage pipe 12.

[0037] like Figures 5 to 8 As shown, the utility model also requests protection for a liquid heating device, including the above-mentioned waste water discharge path structure; it also includes a main body 13, on which a heating kettle body 14 is provided, and the heating kettle body 14 is detachably mounted on the main body 13, so that the heating kettle body 14 can be taken out and filled with water; a cover body 15 is movably provided on the heating kettle body 14, and the movable setting of the cover body 15 is also convenient for removal, so that the heating kettle body 14 can be taken out; a liquid extraction tube 16 is connected to the cover body 15, and the liquid extraction tube 16 is inserted into the heating kettle body 14; an insertion position 1301 is provided on the main body 13, and the insertion position 1301 is connected to the first delivery pipe 6; a matching plug 1501 is provided at a position corresponding to the insertion position 1301 on the cover body 15, and a delivery pipeline is also provided inside the cover body 15, one end of the delivery pipeline is connected to the liquid extraction tube 16, and one end of the delivery pipeline is connected to the plug 1501.

[0038] Therefore, when the cover body 15 is installed on the main body 13, the liquid extraction pipe 16, the delivery pipeline in the cover body 15, the plug nozzle 1501, the insertion position 1301 and the fifth delivery pipe 10 are water-connected, and the water supply pump 3 can be operated to extract the hot water in the heating kettle body 14 into the three-way component 1; the main body 13 is provided with a water outlet 18, and the water outlet 18 is connected to the fifth delivery pipe 10, that is, when a cup is placed under the water outlet 18, the drinking water finally output from the fifth delivery pipe 10 is output from the water outlet 18 to the cup.

[0039] The main body 13 is provided with an installation chamber 1302, and the frame 11 is fixed in the installation chamber 1302 by tightening screws; the main body 13 is movably provided with a waste water tank 17, and the waste water tank 17 is located below the sewage pipe 12; the waste water falls into the waste water tank, and the waste water can be dumped out regularly by taking out the waste water tank, which is very convenient.

[0040] A water collecting pan 19 is movably provided in front of the waste water tank 17. The water collecting pan 19 is located below the water outlet 18. The water collecting pan 19 helps to collect water droplets dripping from the water outlet 18.
