[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] The water in the water tank 1 is connected to the water supply system 1 by a plurality of channels, and the channels are connected to the water supply system 1 by a plurality of channels.

[0032] The purification unit 6 is composed of multiple independent units, including a purification box 61. The purification box 61 is filled with activated carbon. An annular channel 62 is provided inside the purification box 61. A water storage space 63 is provided at the water outlet end of the annular channel 62. The water inlet and the water outlet of the annular channel 62 are not on the same vertical line. In this way, the water discharged from the water outlet of the annular channel 62 will impact the wall surface of the water storage space 63, and the impact force is used to increase the filtration efficiency. A circulation channel 64 is provided at the bottom of the water storage space 63. The circulation channel 64 is connected to the annular channel 62. During the circulation process, the tap water will continue to penetrate downward, and the tap water will preferentially gather in the water storage space 63. In order to achieve the circulation effect, the purification unit 6 needs to be continuously filled with water to improve the circulation efficiency.

[0033] A water diversion channel 12 is provided on the back of the cover plate 8. One end of the water diversion channel 12 is fixedly connected to the tap water inlet 9, and the other end is fixedly connected to the insert pipe 13. The water diversion channel 12 is used to transport tap water to different independent units. By increasing the number of independent units, the purification efficiency is further improved.

[0034] A stop bar 14 is provided at the bottom of the partition 2, and the purification unit 6 is placed on the stop bar 14. The purification unit 6 is not fixed, which facilitates the replacement of the independent unit in the purification unit 6 at a later time.

[0035] The bottom of the purified water storage bin 7 is a concave structure, and an electromagnetic three-way valve 15 is provided at the concave center of the purified water storage bin 7. The vertical downward opening of the electromagnetic three-way valve 15 is connected to the purified water outlet 3 through a hose, and the opening on the other side of the electromagnetic three-way valve 15 is connected to the waste water tank 4 through a hose. The purified water will converge to the concave center of the purified water storage bin 7 and be transported to the purified water outlet 3 or the waste water tank 4 through the electromagnetic three-way valve 15. When flowing to the purified water outlet 3, the vertical opening of the electromagnetic three-way valve 15 is opened and the side opening is closed. When flowing to the waste water tank 4, the vertical opening of the electromagnetic three-way valve 15 is closed and the side opening is opened. In this way, when in use, the purified water will be transported to the purified water outlet 3 first. When the purified water is not in use, the water remaining in the purified water storage bin 7 and the purification unit 6 will be transported to the waste water tank 4, ensuring that no water is stored in the purified water storage bin 7 and the purification unit 6 for a long time at all times to prevent water resource pollution.

[0036] The annular channel 62, the water storage space 63, and the circulation channel 64 are all formed by fixing the activated carbon in a mesh structure. In this way, when the tap water moves, it can impact the annular channel 62, the water storage space 63, and the circulation channel 64, accelerating the speed of water passing through the activated carbon, thereby improving the purification efficiency. Secondly, the gaps between the channels form a multi-level filtration. The tap water located near the water outlet of the annular channel 62 penetrates through the upper half of the annular channel 62 to the lower half of the annular channel 62, and is filtered multiple times, thereby improving the filtration effect.

[0037] The control box 11 is internally provided with a CPU control center and a start switch. The CPU control center is electrically connected to the booster pump 10 and the electromagnetic three-way valve 15. The electromagnetic three-way valve 15 is controlled by the CPU control center to open and close the ports of the electromagnetic three-way valve 15 when purified water is needed to provide people and to empty the purified water storage tank 7 and the purification unit 6.

[0038] The output port of the cannula 13 is plugged into the water inlet of the annular channel 62. The distribution position of the cannula 13 corresponds one-to-one with the water inlet of the annular channel 62 inside the purification box 61. The purpose of plugging into the water inlet of the annular channel 62 is to ensure that the tap water passes through the annular channel 62. On the other hand, the plugging is used to fix the connection between the box body 1 and the cover plate 8.

[0039] The sides of the purification box 61 are fixed with plates, and the upper and lower sides are fixed with a mesh structure to ensure that tap water will not seep out from the sides of the purification box 61 and will only be discharged from the bottom. The activated carbon filled in the purification box 61 is formed by high-pressure extrusion to form a high-density activated carbon space. Since the tap water needs to move and circulate inside the purification box 61, only the high-density activated carbon space can ensure the speed of water flow;

[0040] A submersible pump is provided inside the wastewater tank 4, and the output end of the submersible pump is connected to the wastewater outlet 5. The wastewater tank 4 is connected to the box body 1 through a snap. When the wastewater inside the wastewater tank 4 needs to be used, the wastewater is directly discharged through the submersible pump.

[0041] Working principle:

[0042] During use, the tap water pipe is fixedly connected to the tap water inlet 9, and the tap water is turned on. The tap water will enter the water diversion channel 12 from the tap water inlet 9. In this process, the booster pump 10 will provide water pressure to speed up the water flow. The tap water enters the water inlet of the annular channel 62 on the independent unit in the purification unit 6 through the water diversion channel 12. When the water flow contacts the first corner of the annular channel 62, the water flow will hit the wall of the annular channel 62, accelerating the tap water to enter the activated carbon space. When turning for the second time, it will also hit the wall of the annular channel 62, and then accelerate the tap water to enter the activated carbon space. When the tap water is discharged into the water storage space 63 through the outlet of the annular channel 62, the water flow will hit the wall of the water storage space 63 for the third time, and also accelerate the tap water to enter the activated carbon space. In this way, rapid and efficient purification is achieved. The tap water stored in the water storage space 63 will flow to the annular channel 62 through the circulation channel 64. As the main water flow inside the annular channel 62 circulates again, the purified tap water will gather in the purified water storage tank 7. At this time, the CPU control center inside the control box 11 will open the electromagnetic three-way valve 15 in the direction of the purified water outlet 3, so that the purified water is supplied to people for use. When the faucet of the tap water pipe is closed, the CPU control center will close the electromagnetic three-way valve 15 in the direction of the purified water outlet 3, and at the same time open the electromagnetic three-way valve 15 flowing to the waste water tank 4, so that the residual water in the purified water storage tank 7 and the purification unit 6 is transported to the waste water tank 4. The waste water stored in the waste water tank 4 can be reused for cleaning and watering flowers.
