[0002] The wastewater collection of household water purifiers is also called household water purifiers or water purifiers. It is a water treatment equipment that deeply filters and purifies water according to the requirements of water use. The water purifiers we usually talk about generally refer to small purifiers for household use, most of which are used for the purification of household drinking water. In the existing technology, this kind of household water purifier wastewater collection generally has a wastewater collection box inside the water purifier. The wastewater during cleaning and the wastewater in the cup or waste solution can be poured into the wastewater collection box, and the collected wastewater is used for other purposes such as irrigation. However, the existing wastewater collection box needs to pay attention to the liquid level in the wastewater tank at all times. When the wastewater is almost full, the wastewater inside must be discharged immediately to avoid wastewater backflow and outflow. Frequent observation and manual drainage are time-consuming and labor-intensive, and have poor practicality. At the same time, the wastewater in the wastewater collection box usually contains dirt, especially the water discharged when cleaning the reverse osmosis membrane. These dirt will be deposited or attached to the inner wall, which will cause the internal space to shrink and breed many bacteria. Utility Model Content

[0024] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Example 1

[0026] See also Figures 1-6 In this embodiment, a wastewater collection component of a water purifier is provided, comprising: a shell 1, wherein an upper cavity 11, a middle cavity 12, and a lower cavity 13 are respectively provided inside the shell 1, an RO membrane 14 is provided at the top of the middle cavity 12, a wastewater tank 15 is provided at the bottom of the lower cavity 13, and a sewage pipe 16 is provided at the bottom position of the RO membrane 14 near the wastewater tank 15; a drainage component, wherein the drainage component is provided at the bottom of the sewage pipe 16 for collecting wastewater, and the drainage component comprises: a downpipe 2, a bottom ring 21, a buoyancy ring 22, a limit ring 23, a pressure sensor 24, and a solenoid valve 2 5; A cleaning component is arranged inside the wastewater tank 15 and is used to clean the wastewater tank 15. The cleaning component includes: a waterproof shell 3, a waterproof motor 31, a rotating impeller 32, an ultraviolet germicidal lamp 33 and a waterproof lampshade 34. A filter element group 4 is provided inside the lower cavity 13, a water storage tank 41 is provided inside the upper cavity 11, and a faucet 42 is provided on the side of the outer shell 1 near the water receiving box 26. One end of the faucet 42 is connected to the RO membrane 14 and the water storage tank 41 respectively. A water pipe connector 43 is provided on the other side of the outer shell 1, and one end of the water pipe connector 43 is connected to the filter element group 4.

[0027] During use, the external water supply pipe is connected to the water pipe joint 43, and the switch valves of the water source and the water pipe joint 43 are opened to allow water to enter the filter element group 4. The water is preliminarily filtered by the filter element group 4, and the filtered water enters the RO membrane 14, and is then filtered twice by the RO membrane 14. The water after secondary filtration flows into the water storage tank 41 for storage. The water is discharged from the water storage tank 41 by turning on the tap 42, or the water filtered by the RO membrane 14 flows out from the tap 42, and the sewage from the RO membrane 14 is discharged into the wastewater tank 15 through the sewage pipe 16 for temporary storage. When the water level in the wastewater tank 15 reaches a certain height, the drainage component can drain the water inside the wastewater tank 15 into a pre-connected pipe, and then flow through the pipe to other containers for storage, or directly use. The cleaning component can clean the inside of the wastewater tank 15 to prevent a large amount of impurities from adhering to the inner wall and inhibit bacterial growth.

[0028] Example 2

[0029] On the basis of Example 1, the bottom end of the sewage pipe 16 is detachably connected to the downpipe 2, and the bottom end of the downpipe 2 extends to the inside of the wastewater tank 15. A bottom ring 21 is fixedly connected to the outside of the downpipe 2 near the bottom end, and a buoyancy ring 22 is slidably connected to the outside of the downpipe 2. A limit ring 23 is fixedly installed near the middle position of the outside of the downpipe 2, and a pressure sensor 24 is provided at the bottom of the limit ring 23. A solenoid valve 25 is fixedly installed on the side of the outside of the shell 1 near the wastewater tank 15. A water receiving box 26 is provided on one side of the shell 1, and a grid 27 is provided on the top of the water receiving box 26. The bottom of the water receiving box 26 is tilted downward, and a drain pipe a28 is provided on one side of the water receiving box 26. A one-way valve 29 is respectively provided inside the drain pipe a28 and the downpipe 2. One end of the drain pipe a28 is communicated with the inside of the wastewater tank 15. A drain pipe b210 is fixedly connected to the side of the wastewater tank 15 near the bottom. One end of the drain pipe b210 passes through the wastewater tank 15, extends to the outside and is connected to the solenoid valve 25.

[0030] When in use, the wastewater collected by the water box 26 flows into the wastewater tank 15 along the drain pipe b210. The grid 27 is used to place the container. The wastewater when cleaning the RO membrane 14 flows into the sewer pipe 2 through the sewage pipe 16, and then flows into the wastewater tank 15 from the sewer pipe 2. The drain pipe a28 and the one-way valve 29 inside the sewer pipe 2 can prevent odor from being emitted. As the water level inside the wastewater tank 15 continues to rise, the buoyancy ring 22 floats upward along the outside of the sewer pipe 2. When the buoyancy ring 22 continues to float up and touches the pressure sensor 24 at the bottom of the limit ring 23, the pressure sensor 24 detects the pressure and sends an electrical signal to the solenoid valve 25. The solenoid valve 25 receives an electrical signal and opens, allowing the liquid inside the waste water tank 15 to be discharged along the drain pipe b210. One end of the water outlet of the solenoid valve 25 can be connected to a water pipe, so that the discharged water flows into other large containers for long-term storage for use as irrigation or composting. The waste water continues to flow out, the water level drops, and the buoyancy ring 22 moves downward. After a period of time after the buoyancy ring 22 is separated from the pressure sensor 24, the solenoid valve 25 is closed. The delay closing time can be adjusted to ensure that there is a temporary amount of water in the waste water tank 15. When it is temporarily used, the solenoid valve 25 is manually opened, and the solenoid valve 25 is manually closed after use.

[0031] Example 3

[0032] On the basis of Example 1, a waterproof shell 3 is fixedly installed at the bottom of the wastewater tank 15, and a waterproof motor 31 is provided inside the waterproof shell 3. The top end of the drive shaft of the waterproof motor 31 passes through the waterproof shell 3 and extends to the outside. The top end of the drive shaft of the waterproof motor 31 is fixedly connected to a rotating impeller 32. A plurality of ultraviolet sterilization lamps 33 are fixedly installed at the top of the wastewater tank 15, and waterproof lampshades 34 are respectively fixedly installed on the outside of the plurality of ultraviolet sterilization lamps 33.

[0033] When the wastewater tank 15 needs to be cleaned, the waterproof motor 31 is started to drive the rotating impeller 32 to rotate. The rotating impeller 32 rotates and stirs the wastewater in one direction. The water flows and washes away the stains on the inner wall. The waterproof shell 3 can protect the waterproof motor 31. When the wastewater is stored, the ultraviolet germicidal lamp 33 is turned on to emit ultraviolet light to irradiate the wastewater, thereby inhibiting the growth of bacteria in the wastewater. The waterproof lampshade 34 can prevent the ultraviolet germicidal lamp 33 from contacting the water. After cleaning to a certain extent, the solenoid valve 25 is opened, and the wastewater is connected to the cleaned stains to flow out. After the valve on the sewage pipe 16 is opened, water will continue to flow into the wastewater tank 15, so as to perform multiple cleanings.
