The external raw water is sprayed into the water purification tank 1 through the spray element 3. Due to the structural design of the water purification tank 1, the raw water sprayed by the spray element 3 is in a turbulent state in the water purification tank 1. The primary water purification component 4 in the water purification tank 1 finely separates the raw water in the turbulent state, and then the pure water in the pure water layer is extracted and transported to the filter tank 2. When pure water is transported to the filter cylinder 2, it passes through the secondary water purification component 5 in the filter cylinder 2. The secondary water purification component 5 adopts a precise water purification method of coarse filter material + filter element penetration to further filter and purify the pure water to achieve higher quality. Among them, most of the larger sediments or larger impurities have been separated and purified by the primary water purification component 4 and will not cause blockage of the secondary water purification component 5 in the filter cylinder 2; the water after secondary separation and purification is output from the various water outlet components 6 on the filter cylinder 2, completing the water purification process of a large amount of raw water.

[0023] Specifically, the water purification cylinder 1 is a pressure cylinder, and the internal pressure is constant so that the sprayed water can produce a better turbulent effect.

[0025] In the first embodiment, Figure 2-4As shown, the inverted setting of the conical separation cylinder 41 can make the water ejected by the jet element 3 rotate along the conical separation cylinder 41 as the center, so that the water flow can always maintain a turbulent state; in the turbulent state, the first separation chamber 71, the pure water chamber 72 and the second separation chamber 73 are formed at the bottom of the conical separation cylinder 41 through the first separation baffle 42 and the second separation baffle 43. In the turbulent state, microorganisms and bacteria lighter than pure water will float on the upper layer, thereby being separated into the first separation chamber 71, and large particles heavier than pure water will float on the upper layer, thereby separating ... Suspended matter, sediment, impurities, etc. will settle, and then pass through the gap between the first partition baffle 42 and the water purification tank 1 and the discharge port 431 of the second partition baffle 43 in turn, thereby being accumulated and separated into the second separation chamber 73. Pure water will be separated into the pure water chamber 72. While flowing continuously, it will enter the water inlet 411 on the conical separation cylinder 41 and enter the conical separation cylinder 41.

[0031] Specifically, after a period of use, when a large amount of separated sediment and microorganisms are present, the sewage pipe 8 can be opened to discharge the separated sewage from the water purification tank 1 to avoid excessive blockage resulting in inability to use and purify water normally.

[0032] Furthermore, the spray component 3 includes: at least one water injection pipe 31, a return ring 32 for receiving the water source input by the water injection pipe 31, and at least one injection head 33 for spraying the water in the return ring 32; the return ring 32 is located in the clean water chamber 11; the water injection pipe 31 is detachably connected to the return ring 32 and is communicated with the return ring 32; the water injection pipe 31 is located outside the clean water cylinder 1; the injection head 33 is detachably connected to the return ring 32, and the injection head 33 is communicated with the return ring 32; the injection head 33 is located in the clean water chamber 11.

After a period of use, in order to prevent the filtered impurities from being blocked and causing normal filtration to fail, the impurities in the water purification tank 1 are discharged through the sewage pipe 8, thereby increasing the service life and avoiding the need for frequent replacement of filter elements like traditional water filtration structures, further increasing the adaptability to scenarios.
