Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a valve-controlled full-automatic water purifier. Background Art

[0002] A water purifier, also called a water purifier or water purifier, is a water treatment device that deeply filters and purifies water according to the requirements for water use. The water purifier we usually talk about generally refers to a small purifier used for home use. Its technical core is the filter membrane in the filter element device, and the main technologies come from three types: ultrafiltration membrane, RO reverse osmosis membrane, and nanofiltration membrane.

[0003] At present, the existing water purifiers directly discharge the tap water from the water outlet of the RO reverse osmosis membrane filter element after purifying it. However, due to the large resistance of the RO reverse osmosis membrane filter element, although a booster pump is provided inside the water purifier, the water output is still relatively small and not stable enough. In addition, when the filter element inside the water purifier is seriously clogged, the existing water purifier does not have the function of timely reminding to replace the filter element. Therefore, the utility model proposes a valve-controlled fully automatic water purifier. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a valve-controlled full-automatic water purifier.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a valve-controlled fully automatic water purifier, comprising a bottom box, a water storage tank is fixed on the upper surface of the bottom box, a PP filter element, an activated carbon filter element, an RO filter element and a booster pump are installed inside the bottom box, the water inlet of the PP filter element is fixedly connected to a water inlet pipe, the water outlet of the PP filter element is connected to the water inlet of the activated carbon filter element through a pipeline, the water outlet of the activated carbon filter element is connected to the water inlet of the booster pump through a pipeline, the water outlet of the booster pump is connected to the water inlet of the RO filter element through a pipeline, the water outlet of the RO filter element is connected to the water inlet of the RO filter element through a pipeline, the water outlet of the RO filter element and the bottom of the water storage tank are commonly connected with a drain pipe, the side wall of the bottom end of the water storage tank is fixedly connected to the water outlet pipe, the top of the water storage tank is fixedly connected to a top cover, the upper surface of the top cover is fixed with a sterilization component, the middle part of the drain pipe is fixedly connected, an alarm is fixed on the upper surface of the bottom box, a controller is fixedly connected to the top wall inside the bottom box, and an operation panel electrically connected to the controller is installed on the outer side wall of the water storage tank.

[0006] Furthermore, a first solenoid valve is fixedly connected to the middle of the water inlet pipe, and a second solenoid valve is fixedly connected to the middle of the water outlet pipe. The first solenoid valve, the second solenoid valve and the booster pump are all electrically connected to the controller.

[0007] Furthermore, a liquid level sensor is fixedly connected to the top of the inner wall of the water tank, and the liquid level sensor is electrically connected to the controller.

[0008] Furthermore, a one-way valve is fixedly connected to one end of the drain pipe close to the RO filter element.

[0009] Furthermore, the wastewater outlet of the RO filter element is fixedly connected to a wastewater pipe.

[0010] Furthermore, the sterilization component includes a top shell fixed to the upper surface of the water tank, an ultraviolet lamp is fixed inside the top shell, and transparent glass is fixed on the top wall of the water tank and inside the top shell.

[0012] Beneficial effects of the utility model:

[0013] 1. When the utility model is in use, the valve controls the fully automatic water purifier, and a bottom box, a PP filter element, an activated carbon filter element, an RO filter element, a booster pump, a water tank, a sterilization component and a controller are arranged. The tap water can be temporarily stored in the water tank after being filtered through the PP filter element, the activated carbon filter element and the RO filter element in sequence. When in use, the water can be drained through the outlet pipe at the bottom of the water tank. After the drainage is completed, the booster pump will continue to work for a period of time to ensure that there is always water in the water tank, thereby ensuring a large and stable water output. In addition, the sterilization component can prevent bacteria from growing inside the water tank.

[0014] 2. When the utility model is in use, the valve controls the fully automatic water purifier, and a flow meter and an alarm are set. When the flow meter detects that the amount of water discharged from the RO filter element is lower than the lower limit, it means that the filter element in front is seriously clogged. At this time, the alarm sounds an alarm, which can remind you to replace the filter element in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The flow meter 15 and the alarm 18 are both electrically connected to the controller 16 .

[0024] A first solenoid valve 13 is fixedly connected to the middle of the water inlet pipe 7 , a second solenoid valve 14 is fixedly connected to the middle of the water outlet pipe 12 , and the first solenoid valve 13 , the second solenoid valve 14 and the booster pump 5 are all electrically connected to the controller 16 .

[0025] In this embodiment, an instruction can be sent to the controller 16 through the operation panel 17, and then the controller 16 can automatically control the first solenoid valve 13, the second solenoid valve 14 and the booster pump 5 to open or close.

[0026] A liquid level sensor 19 is fixedly connected to the top of the inner wall of the water tank 6 , and the liquid level sensor 19 is electrically connected to the controller 16 .

[0027] The water level in the water tank 6 can be monitored by the liquid level sensor 19. When the water level is lower than the liquid level sensor 19, the controller 16 will control the first solenoid valve 13 and the booster pump 5 to open.

[0028] A one-way valve is fixedly connected to one end of the drain pipe 8 near the RO filter element 4. By setting the one-way valve, the pure water discharged from the RO filter element 4 can only enter the water storage tank 6 along the drain pipe 8 to avoid water backflow.
