[0026] In this embodiment, the filter box 1, the filter assembly 2, the installation box 3 and the disinfection box 4 constitute the main structure of the rural drinking water multi-stage filtration device involved in this application.

[0027] Specifically, the electric push rods 13 are symmetrically arranged on both sides of the installation box 3, and the lower side of the lower end plate 14 is connected with a support leg to achieve stable support for the entire device.

[0028] Specifically, a control box is provided at the rear side of the disinfection box 4, and the control box is electrically connected to the ultraviolet disinfection lamp 41. At the same time, the ultraviolet disinfection lamp 41 is provided with multiple groups of horizontal layers inserted in the disinfection box 4, thereby increasing the irradiation area and range of the light.

[0029] It should be noted that it usually takes only a few tenths of a second for water to flow through the surface of the quartz tube of the ultraviolet lamp to achieve the disinfection effect.

[0030] like Figure 2As shown, an inner cavity 15 connected to the water inlet 12 is provided inside the filter box 1, and a sealing gasket 16 is provided on the lower edge of the filter box 1, and a guide rod 17 is connected to the lower end of the filter box 1, a mounting groove 31 is provided on the upper side of the mounting box 3, and a guide hole 32 is provided on the outer side of the mounting groove 31, and a guide hole 33 connected to the mounting groove 31 is provided on the lower side, and the guide hole 32 is matched and plugged with the guide rod 17.

[0031] As a preferred embodiment, by providing the guide rod 17 and the guide hole 32, the filter box 1 and the installation box 3 are conveniently connected to each other, and the inner cavity 15, the installation groove 31 and the guide hole 33 ensure smooth water flow.

[0032] like Figures 3 to 7 As shown, the filter plate 22 includes a mesh layer 221 arranged on the upper and lower sides, and a material layer 222 is arranged between the mesh layers 221, and a clamping groove 223 is opened on the upper side of the rear end of the filter plate 22, and a blocking groove 224 connected to the clamping groove 223 is opened on the lower side, and the front end of the filter plate 22 is movably connected to a protrusion assembly 24, and the protrusion assembly 24 includes a pull button 241 located on the front side of the filter plate 22, and the rear side of the pull button 241 is connected to a slide rod 242. An active cavity 243 is provided inside the filter plate 22, and a slider 244 and a spring 245 are provided in the active cavity 243, and the front side of the slider 244 is connected to the slide bar 242, and the spring 245 is located at the rear side of the slider 244, and an insert block 23 is slidably inserted at the rear side of the filter plate 22, and the insert block 23 includes a flat plate 231 on the upper side, and a vertical plate 232 is connected to the lower end of the flat plate 231, and the insert block 23 is matched and inserted in the snap-in groove 223 and the blocking groove 224.

[0033] Specifically, after the filter plate 22 is slidably inserted into the fixing box 21, the plug block 23 at its rear end maintains contact with the rear inner wall of the fixing box 21. At the same time, when the filter assembly 2 slides downward and is inserted into the installation box 3, the pull button 241 on the front side of the filter plate 22 is squeezed and moved inward, thereby maintaining elastic contact with the front inner wall of the installation box 3.

[0034] Specifically, the filter plate 22 is configured as an upper and lower layer structure, and each filter material layer 222 is made of different materials, including filter cotton, activated carbon, and medical stone particles.

[0035] It should be noted that the drinking water flowing downward through the inner cavity 15 is aligned with the center of the filter plate 22 , and the uppermost filter plate 22 is lower than the upper edge of the fixing box 21 , so that the drinking water is restricted to flow inside the fixing box 21 .

[0036] When in use, the water inlet is connected through the water inlet pipe, and then filtered and disinfected through the filter box, installation box and disinfection box, and finally discharged through the drain outlet. When disassembling, first start the electric push rod to push the filter box upward. At this time, the filter assembly is moved out from the inside of the installation box, and the pull button pops outward under the action of the spring. Then, according to the layer of filter plate that needs to be replaced, it can be directly pulled out through the pull button, and then the plug block is pulled upward to open the sealing groove on the back side of the filter plate. Then, the internal material layer can be taken out and the filter material of the core can be replaced, so as to facilitate the independent replacement of the filter material of each layer; the ultraviolet disinfection lamp arranged inside the disinfection box allows the drinking water that has been preliminarily filtered by the filter assembly inside the filter box to flow downward into the disinfection box, and then be disinfected by the ultraviolet disinfection lamp, so as to further improve the hygiene of the drinking water.

[0037] The rural drinking water multi-stage filtering device of the utility model can effectively solve the problem that the existing drinking water multi-stage filtering treatment devices still have the problem of troublesome replacement of filtering materials, and the problem that the existing drinking water disinfection method using chlorine gas causes the drinking water to have odor. It realizes the convenience of individual replacement of filtering materials on the basis of the existing rural drinking water multi-stage filtering device technology, and is easy to operate, and adds a disinfection function on the basis of avoiding odor.
