[0011] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0012] like Figure 1 As shown, the utility model provides a kitchen water purifier with stepless temperature adjustment, including a faucet 23, the faucet 23 is respectively connected to an exhaust pipeline 24, a hot water pipeline 13 and a normal temperature water pipeline 10, the exhaust pipeline 24 is connected to a hot tank 25, a hot water pump 15 is installed on the hot water pipeline 13 and is connected to the hot tank 25, the normal temperature water pipeline 10 is connected to an RO filter element 5, a first temperature probe 12 and a flow meter 9 are installed on the normal temperature water pipeline 10, the RO filter element 5 is connected to external tap water through a first pipeline 2, a first water inlet valve 3 is installed on the first pipeline 2, the bottom of the hot tank 25 is connected to the hot water pump 15 through a second pipeline 17, a drain valve 16 is installed on the second pipeline 17, a second temperature probe 11 is installed on the hot tank 25, and a second water inlet valve 19 is installed on the connecting pipeline 22 between the normal temperature water pipeline 10 and the hot tank 25.

[0013] Specifically, the first temperature probe 12 is used to detect the temperature A of the filtered normal temperature water, while the flow meter 9 can detect the flow rate B of the filtered normal temperature water, and then the water temperature C of the hot water outlet of the hot tank 25 is detected by the second temperature probe 11. In this way, the flow rate D of the hot water in the hot tank 25 output by the hot water pump 15 can be obtained according to the water temperature F of the faucet 23 selected by the user. When the temperature A, flow rate B and water temperature C do not change much, the flow rate D of the hot water can be controlled by the voltage of the hot water pump 15 to adjust the water temperature F, thereby realizing the function of stepless temperature regulation.

[0014] Normal temperature water is input from tap water, enters the RO filter element 5 along the first pipeline 2 for filtration, and then enters the faucet 23 along the normal temperature water pipeline 10. The second pipeline 17 at the bottom of the hot tank 25 can also transport hot water to the hot water pump 15.

[0015] In order to monitor the water in the hot tank 25, at least one liquid level sensor 21 is installed inside the hot tank 25. Three liquid level sensors 21 can be set to monitor the high water level, the middle water level and the low water level respectively, and have an anti-burning function.

[0016] In order to improve the water purification effect, a post-carbon rod filter element 8 is also installed on the normal temperature water pipeline 10, and a pre-composite filter element 1 is installed on the first pipeline 2. The post-carbon rod filter element 8 and the pre-composite filter element 1 can perform multi-layer filtration on tap water to ensure the water purification effect.

[0017] At the same time, the RO filter element 5 is also connected to a waste water pipe, and a waste water valve 7 is installed on the waste water pipe, so that the waste water filtered out of the RO filter element 5 can be quickly discharged.
