Description

Technical Field

[0001] This utility model relates to the field of purification structure technology, specifically to a purification structure for pipeline drinking water equipment. Background Technology

[0002] Piped drinking water systems are systems that use specific water treatment processes and pipeline systems to deeply purify water sources before delivering them to users through a closed pipeline network, providing high-quality drinking water for direct consumption. They are commonly used in residential communities, office buildings, schools, hospitals, and other locations, serving as a centralized drinking water solution. The water source is typically municipal tap water, but can also be groundwater or surface water, meeting certain water quality standards as raw water. Before use, the water source requires pretreatment and purification; the pretreatment unit removes large particulate impurities, suspended solids, colloids, and other contaminants from the raw water.

[0003] A search revealed Chinese patent number CN202421002399.2, which discloses a purification structure for a piped drinking water system. The structure includes an inlet pipe and an outlet pipe, with an outer filter box connected between them. An inner filter box is movably disposed within the outer filter box and can be removed from the outer filter box. The inner filter box is connected to both the inlet and outlet pipes and contains a primary filtration device. Water flows through the inlet pipe into the inner filter box, is filtered by the primary filtration device, and then enters the outlet pipe. A detachable filter screen is installed in the outlet pipe, providing secondary filtration for the water flowing through it. Both the inner filter box and the filter screen in this invention can be removed for cleaning or replacement to prevent clogging.

[0004] However, the above solution still has its drawbacks. When it is necessary to clean or replace the filter bucket or filter screen, multiple first fixing screws or multiple second fixing screws need to be removed. After cleaning or replacement, the multiple first fixing screws or multiple second fixing screws need to be reinstalled. Such operation is too time-consuming and laborious, which reduces the efficiency of cleaning or replacing the filter bucket or filter screen and brings a bad user experience. Utility Model Content

[0029] Please see Figures 1-7 This application provides a technical solution: a purification structure for a pipeline drinking water equipment, including an inlet pipe 110, an outer filter box 120, an outlet pipe 130, a sleeve 140, an inner filter box 150, a filter bucket 170, a limiting frame 180, a filter plate 191, a column 195, and a locking mechanism 196. One end of the inlet pipe 110 and one end of the outlet pipe 130 are both set on the outer filter box 120, and the sleeve 140 is set on the outlet pipe 130. It also includes an anti-corrosion layer 190, which is fixed inside the inlet pipe 110. The anti-corrosion layer 190 provides better protection for the inlet pipe 110.

[0030] The filter bucket 170 is fixed inside the inner filter box 150, which is slidably inserted into the outer filter box 120. It also includes a retaining ring 160, which is fixed inside the inner filter box 150. The retaining ring 160, inlet pipe 110, filter bucket 170, and outlet pipe 130 are correspondingly arranged. The filter plate 191 is slidably inserted into the insert sleeve 140. A limiting bracket 180 is fitted onto the insert sleeve 140 and the filter plate 191. The limiting bracket 180 is also fitted onto... The filter plate 191 is mounted on the column 195 and includes a first sealing gasket 192 and a second sealing gasket 194. The first sealing gasket 192 is fitted on the limiting frame 180 and the second sealing gasket 194 is fitted on the filter plate 191. The filter plate 192 also includes a first sealing liner 193 and a second sealing liner 197. The first sealing liner 193 is installed between the insert 140 and the filter plate 191, and the second sealing liner 197 is installed between the outer filter box 120 and the inner filter box 150.

[0031] The locking mechanism 196 is installed on the outer filter box 120 and the column 195. The locking mechanism 196 is set to quickly assemble the limit frame 180 onto the outer filter box 120 and the sleeve 140. The locking mechanism 196 includes an L-shaped block 1961, a rod 1962, a horizontal plate 1963 and a spring 1964. The L-shaped block 1961 is fixed on the outer wall of the outer filter box 120. The rod 1962 slides through the L-shaped block 1961 and is fixed on the horizontal plate 1963. The spring 1964 is fixed between the L-shaped block 1961 and the horizontal plate 1963 and passes through the spring 1964. The rod 1962 also slides through the column 195. Several columns 195 are provided on the upper surface of the outer filter box 120. The several columns 195 are linearly and equidistantly installed on the upper surface of the outer filter box 120.

[0032] The working principle and process of this utility model are as follows: When cleaning the filter bucket 170 or filter plate 191, pull the horizontal plate 1963 to disengage the insertion rod 1962 from the column 195. Then, lift the limiting frame 180 to separate it from the outer filter box 120 and the insert sleeve 140. Next, sequentially remove the inner filter box 150 and filter plate 191 for cleaning. After cleaning, pull the horizontal plate 1963 again, bringing one end of the horizontal plate 1963 as close as possible to the L-shaped block 1961. Then, insert the inner filter box 150 into the outer filter box 120 and the filter plate 191 into the insert sleeve 140. The limiting bracket 180 is fitted onto the column 195, filter plate 191, and insert 140. The limiting bracket 180 is pressed down so that it fits against the outer filter box 120. Then the horizontal plate 1963 is released, and under the reaction force of the spring 1964, the insert rod 1962 passes through the column 195, thus restricting the limiting bracket 180 to the outer filter box 120 and insert 140. The purification structure of this pipeline drinking water equipment facilitates the quick assembly and disassembly of the limiting bracket 180, as well as the quick assembly and disassembly of the filter bucket 170 and filter plate 191, without the need to separate the assembly and disassembly of the filter bucket 170 and filter plate 191, saving time and effort and providing users with a better user experience.

[0033] The embodiments of this utility model have been described in detail above, but the content is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
