[0024] Example 1:

[0025] Please see Figure 1 As shown, this utility model provides a drinking water filtration device that is easy to maintain, including a water storage tank 1. A water quality sensor 2 is installed on the back of the inner cavity of the water storage tank 1. A display panel 3 and an indicator light 4 are respectively installed on both sides of the front of the water storage tank 1. Vertical positioning seats 9 are symmetrically installed on the front and back of the right side of the inner cavity of the water storage tank 1. A precision filter screen 10 is vertically snapped between the two vertical positioning seats 9. A flow guide plate 11 is snapped above the precision filter screen 10. Horizontal fixing seats 15 are fixedly installed at both the front and back ends of the left side of the inner cavity of the water storage tank 1. A filter screen plate 16 is snapped above the horizontal fixing seat 15. A support spring 17 is installed between the horizontal fixing seat 15 and the inner wall of the water storage tank 1. An adjusting plate 18 is installed on the inner end of the support spring 17. A positioning block 19 is installed on the inner side of the adjusting plate 18. The inner end of the positioning block 19 is snapped into the inside of the horizontal fixing seat 15 and connected to the protrusion at the bottom of the filter screen plate 16.

[0026] This technical solution achieves quick assembly and disassembly of the filter screen 16 through the cooperation of the horizontal fixing seat 15, the support spring 17, the adjusting plate 18 and the positioning block 19. The vertical positioning seat 9 cooperates with the bearing seat 13 to achieve convenient fixation of the precision filter screen 10, which greatly simplifies the maintenance operation of the filter components. The water quality sensor 2 can monitor the water quality in real time, which makes it convenient for users to understand the filtration effect and perform maintenance in a timely manner. The overall structure is reasonably designed, easy to operate, has a stable filtration effect and strong practicality.

[0027] Example 2:

[0028] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, a sealing ring 5 is installed on the outer ring of the top of the water storage tank 1. A sealing groove 6 is opened inside the sealing ring 5. A sealing top cover 7 is snapped on the top of the sealing groove 6 and located on the top of the water storage tank 1. A water inlet pipe is connected to the left side of the top of the sealing top cover 7. A support seat 13 is installed on the upper right side of the inner cavity of the water storage tank 1. A plug-in block 12 is vertically snapped on the inside of the support seat 13. The upper end of the plug-in block 12 is connected to the right end of the bottom of the precision filter screen 10.

[0029] Adopting such Figure 1 The technical solution shown features a sealing ring 5 on the outer top of the water tank 1. The sealing groove 6 inside the sealing ring 5 precisely matches the snap-fit ​​structure at the bottom of the sealing top cover 7, achieving a reliable seal between the water tank 1 and the sealing top cover 7. This effectively prevents external impurities from entering the tank and contaminating the water to be filtered, while also ensuring the device's leak-proof performance. The support seat 13 on the upper right side of the inner cavity of the water tank 1 and the plug block 12 connecting to the bottom right end of the precision filter screen 10 adopt a vertical snap-fit ​​design. This not only provides stable support and positioning for the precision filter screen 10, ensuring the structural stability of the filter screen during filtration, but also simplifies the disassembly and assembly process of the precision filter screen 10, allowing for quick maintenance or replacement of the filter screen without additional tools.

[0030] Secondly, in the technical solution, a positioning vertical plate 14 is longitudinally installed at the upper end of the inner cavity of the water storage tank 1 and at the right end of the filter screen plate 16. The left side of the positioning vertical plate 14 is sealed and fitted with the right end of the filter screen plate 16. The positioning vertical plate 14 is connected to the left side of the vertical positioning seat 9. The lower left end of the guide plate 11 is designed with an inclination and a gap is left between it and the positioning vertical plate 14.

[0031] Its adoption is as follows Figure 1The technical solution shown effectively prevents water from leaking through the gap between the two and affecting the filtration effect. At the same time, the positioning plate 14 is connected to the left side of the vertical positioning seat 9, which not only provides a stable lateral positioning for the filter screen plate 16 and prevents the filter screen from shifting during the filtration process, but also enhances the overall stability of the installation structure of the vertical positioning seat 9 and the filter screen plate 16. The inclined design of the lower left end of the guide plate 11 can guide the water to be filtered to the filter screen plate 16 to be evenly distributed, avoiding the water flow from concentrating and impacting the filter screen locally, which would lead to uneven filtration.

[0032] Example 3:

[0033] This utility model is as follows Figures 1-6 As shown, a through groove is provided inside the transverse fixing seat 15, and the protrusion at the bottom of the filter screen plate 16 is engaged with the inside of the through groove. In addition, a moving groove is provided longitudinally on the outside of the transverse fixing seat 15, and one end of the positioning block 19 passes through the moving groove and is engaged with the inside of the protrusion. A drain pipe 8 is connected to the bottom right side of the water storage tank 1, and a control valve is movably installed on the surface of the drain pipe 8. A rectangular bracket is installed at the bottom of the sealing top cover 7, and the lower end of the rectangular bracket is engaged with the inside of the sealing groove 6 and makes a sealing contact.

[0034] Using the above technical solution, the through groove inside the transverse fixing seat 15 and the bottom protrusion of the filter screen plate 16 form a precise engagement, providing a reliable initial positioning for the filter screen plate 16. In conjunction with the longitudinally opened moving groove on the outside of the transverse fixing seat 15, the positioning block 19 can smoothly pass through and engage inside the protrusion, achieving a stable fixation of the filter screen plate 16. Moreover, the filter screen can be disassembled and assembled by manipulating the positioning block 19 without additional tools, greatly improving the convenience of maintenance.

[0035] The working principle of this utility model is as follows: Water to be filtered is injected into the water storage tank 1 through the water inlet pipe. The water flows through the filter screen 16 to perform preliminary filtration of large particles in the water. The water after preliminary filtration then passes through the precision filter screen 10 for deep filtration to remove fine impurities. The water quality sensor 2 monitors the water quality after filtration in real time and transmits the data to the display panel 3. Users can intuitively understand the water quality through the display panel 3. When the water quality does not meet the standard, the indicator light 4 will light up as a warning. When maintenance is required, open the sealed top cover 7, pull the adjustment plate 18 outward, take out the filter screen 16 for cleaning or replacement, and pull out the precision filter screen 10 upward for maintenance.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
