Problems solved by technology

Although the water purifier is simple in structure and easy to use, its disadvantage is that the multi-layer water purifying chamber in the casing leads to slow water discharge, which is difficult to meet people's requirements.
Because there are three water purification cylinders, not only the product structure is complicated, the cost is high, but also it takes up a lot of space when placed

Embodiment Construction

[0023] Such as figure 1 with figure 2 As shown, the backwash type deep water purifier includes a housing 1, a water inlet pipe 2, an outlet pipe 3, a filter material 4, a backwash sewage pipe 7 and other parts. The casing 1 is composed of an outer casing 11 and an inner casing 12 . In this embodiment, the outer casing 11 is cylindrical. The shape of the outer shell 11 can also be square, triangular and other shapes. The inner casing 12 is placed in the outer casing 11 and its shape is similar to that of the outer casing 11 .

[0024] Such as figure 2 with image 3 As shown, there is a drainage gap 13 between the inner shell 12 and the outer shell 11 for water to flow through. In this embodiment, the drainage gap 13 is naturally formed by the size difference between the inner casing 12 and the outer casing 11 . The drainage gap 13 can also be several drainage holes provided between the inner casing 12 and the outer casing 11, which can also achieve the same purpose.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a civil water purification device. Background technique [0002] Existing residential water is usually transported to users by waterworks through large, medium and small water delivery pipelines. Finally, the quality of tap water used by users is often poor. The reason is that, on the one hand, most of the source water is polluted to varying degrees due to the discharge of industrial waste water, waste gas, and pesticides. During the water delivery process, the rust and deposited pollutants in the water pipes cause secondary pollution to the tap water, further deteriorating the water quality and affecting people's drinking water health. [0003] Therefore, at present, whether it is a family, an enterprise or a school, etc., water purification devices are widely used to improve water quality and reduce and prevent pollution to the human body.
