[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0025] Combine Figures 1 to 4 The filtration structure of an RO pure water device shown in the figure includes a pure water device body 1 and a top cover 2 mounted on the top of the pure water device body 1. Support plates 3 are fixedly mounted on the two outer side walls of the pure water device body 1. The support plates 3 are mounted on a supporting mechanism 4 for lifting the top cover 2. An inner cylinder 5 is disposed within the pure water device body 1. The top of the inner cylinder 5 is connected to the bottom of the top cover 2. A first filter screen 6 for uniform water filtering is mounted within the inner cylinder 5. A mounting frame 7 is provided below the first filter screen 6. The mounting frame 7 is movably mounted on the inner cylinder 5 and contains a double-layer filter plate 8.

[0026] Among them, the two support plates 3 are equipped with a supporting mechanism 4, which includes a telescopic cylinder 41 fixedly installed on the top of the support plate 3, and one end of the telescopic rod of the telescopic cylinder 41 is fixedly connected with a top plate 42, and the top of the top plate 42 is mounted on the bottom of the top cover 2 through a slot; a guide plate 9 is fixedly installed on the outer wall of the pure water equipment body 1 on one side of the support plate 3, and the telescopic rod of the telescopic cylinder 41 passes through the guide plate 9; a mounting opening 51 is provided on the side wall of the inner cylinder 5, and a fixed plate 52 is provided on both sides of the mounting opening 51 for supporting the mounting frame 7 to move; when the double-layer filter plate 8 needs to be replaced, the telescopic cylinders 41 on both sides are started, and their telescopic rods are guided by the guide plates 9 and use the top plate 42 to push the top cover 2 upward until the mounting opening 51 is exposed, and the mounting frame 7 can be pulled out through the mounting opening 51 and the fixed plate 52, and then the double-layer filter plate 8 can be replaced. After the replacement is completed, the telescopic cylinder 41 can be reset;

[0027] The first filter screen 6 is in a cone-shaped configuration and has a plurality of filter holes 61 therein. During use, raw water flows from the water inlet pipe 10 to the top of the first filter screen 6. The raw water then disperses from the top of the cone-shaped first filter screen 6 and flows downward. The raw water then slides up and down the first filter screen 6 while falling through the plurality of filter holes 61. This ensures that the water flows evenly downward through the filter holes 61 on the first filter screen 6, effectively increasing the filtration surface area and filtration effect, and enabling the double-layer filter plate 8 below to evenly filter the raw water. The double-layer filter plate 8 includes an activated carbon filter screen 81 and a graphene filter screen 82. Through this dual filtration, the water is effectively removed from the water, including odors, residual chlorine, heavy metals, and other harmful substances, thereby improving the purity and taste of the water.

[0028] A water inlet pipe 10 is installed on the top cover 2, and a water outlet pipe 11 is installed at the bottom of the pure water equipment body 1, and valves 12 are installed on the water inlet pipe 10 and the water outlet pipe 11; a support leg 13 is connected to the bottom of the support plate 3; when in use, external water is transported to the inner cylinder 5 through the water inlet pipe 10, and after filtration, it is output through the water outlet pipe 11 or undergoes the sterilization operation of the next link; and the support leg 13 enhances the stability and carrying capacity of the overall equipment.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
