[0037] The utility model will be described in more detail in the following paragraphs with reference to the drawings. The advantages and features of the utility model will be more apparent from the following description and claims. It should be noted that the drawings are all very simplified and use non-precise proportions, and are only used to facilitate and clarify the purpose of assisting the description of the embodiments of the utility model. Figure 1 To the drawings Figure 3 The filter of the utility model is introduced.

[0038] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the filter of the present application comprises a housing 100, a liquid inlet assembly and multiple filter layers. The housing 100 has an inner cavity, and the multiple filter layers are arranged in the inner cavity of the housing 100. The liquid inlet assembly comprises a water inlet pipeline and a liquid baffle 130, the lower end of the water inlet pipeline has a water outlet and extends into the inner cavity of the housing 100, and the liquid baffle 130 is fixed below the water outlet to change the flow direction of the water.

[0039] In use, the housing 100 provides a space to accommodate the filter layers, the liquid inlet assembly introduces water into the inner cavity of the housing 100 through the water inlet pipeline, and changes the flow direction of the water through the liquid baffle 130, so that the water flow does not directly impact the filter layers, and the suspended particles in the water are located in the upper layer of the water, and do not directly act on the filter layers, forming a kind of cross-flow filtration, reducing the possibility of filter layer caking, and prolonging the service life of the filter.

[0040] Further, in one embodiment, the filter layers have four layers, from top to bottom, coarse sand layer 210, fine sand layer 220, activated carbon layer 230 and resin layer 240, and in other embodiments, only three filter layers can be provided.

[0041] Further, in one embodiment, as shown in Figure 2 , the liquid baffle 130 has an arc-shaped guide surface.

[0042] Specifically, the arc-shaped guide surface changes the direction of the water flow, so that the water flow does not directly return to affect other water flows and is more dispersed to the four directions, while reducing the direct impact of the water flow on the liquid blocking plate 130 and the filter layer. As a preferred embodiment, the arc-shaped guide surface can be designed as a semicircle or an ellipse to better disperse the water flow and reduce the impact on the liquid blocking plate 130 and the filter layer. In addition, the arc-shaped guide surface can further enhance the dispersion effect of the water flow by increasing the surface roughness.

[0043] Further, in one of the embodiments, a flared structure is provided on the water outlet.

[0044] The flared structure can take various forms, such as the trumpet mouth 121. This feature slows down the speed of the water flow by increasing the diameter of the water outlet, disperses the water flow, thereby reducing the direct impact of the water flow on the filter layer, reducing the direct impact and contact of suspended particulate matter with the filter layer, reducing the possibility of combination of suspended particulate matter with the filter layer, effectively preventing the clogging and failure of the filter layer, and improving the service life of the filter. As a preferred embodiment, the shape of the trumpet mouth 121 can be designed as a gradually expanding cone to better disperse the water flow and reduce the impact on the filter layer.

[0045] Further, in one of the embodiments, a plurality of buffer through holes 131 are provided on the liquid blocking plate 130.

[0046] Specifically, the design of the buffer through hole 131 can disperse the pressure of the water flow and reduce the direct impact of the water flow on the liquid blocking plate 130. This design helps to improve the service life of the liquid blocking plate 130, thereby prolonging the overall service life of the filter. The shape and size of the buffer through hole 131 can be adjusted according to actual application requirements, for example, it can be designed as a circle, a square or other geometric shapes to adapt to different water flow conditions and filtration requirements. In addition, the distribution of the buffer through hole 131 can also be optimized according to the structure of the liquid blocking plate 130 to ensure that the water flow is evenly dispersed when passing through the liquid blocking plate 130, reducing local pressure concentration. In other embodiments, the buffer through hole 131 can not be provided, but the structural strength of the liquid blocking plate 130 can be improved.

[0047] Further, in one of the embodiments, the liquid blocking plate and the water inlet pipeline are fixedly connected through the connecting rod 140.

[0050] Specifically, the bent rod can be fixed with the water inlet pipeline and the liquid baffle 130 through welding, bolt connection or other mechanical fixing methods. As a preferred embodiment, the bent rod can be made of stainless steel to enhance its corrosion resistance and strength. In addition, the shape of the bent rod can be adjusted according to actual installation requirements, for example, it can be designed as an arc or S shape to better adapt to different installation environments and space limitations.

The fixed pipe section 122 penetrates the upper head 110 and is fixedly connected thereto. The water outlet is arranged at the end of the water spraying pipe section 123.

[0055] Specifically, the fixed pipe section 122 and the water spraying pipe section 123 are fixedly connected by a clamp, which ensures the stability and sealing of the water inlet pipeline. The fixed pipe section 122 penetrates the upper head 110 and is fixedly connected thereto, which not only enhances the stability of the structure, but also ensures the smooth flow of water.
