[0002] A pipeline water dispenser, also known as a pipeline water purifier or wall-mounted pipeline water purifier, is a terminal drinking water device that connects to a water purification system and is mainly used in homes, offices, and other places. Current water dispensers filter tap water using built-in filters, which are typically composed of PP cotton and activated carbon to remove bacteria and colloids from the water. However, because modern water dispensers are integrated units with the filters located inside the machine, their filtration efficiency decreases significantly after prolonged use, requiring frequent replacements. This necessitates disassembling the entire water dispenser for replacement, thus reducing the practicality of modern water dispensers. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide a water purifier with a built-in filter pipeline.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a water purifier with a built-in filter pipeline, comprising a pipeline body and an external filter element.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-5As shown, this utility model provides a water purifier with a built-in filter pipeline, including a pipeline body 1 and an external filter. The external filter specifically includes a treatment box 12, which is located at the water inlet of the pipeline body 1. A water inlet pipe 11 is connected to the water inlet of the pipeline body 1. The end of the water inlet pipe 11 away from the pipeline body 1 is connected to the treatment box 12. An input pipe 13 is connected to the end of the treatment box 12 away from the pipeline body. The input pipe 13 is connected to an external water pipe. Tap water is filtered first by the filter assembly 14 in the treatment box 12 and then enters the pipeline body through the water inlet pipe 11. The filter assembly 14 is located inside the treatment box 12. The filter assembly 14 is composed of PP cotton, activated carbon, and an ultrafiltration membrane, which can remove bacteria and colloids while retaining minerals. A filter is fixed on the top of the filter assembly 14. Mounting block 15 penetrates the upper end of processing box 12. The top of processing box 12 is provided with cover plate 16. The top of mounting block 15 is inserted into the lower end of cover plate 16. Vertically positioned positioning rods 17 are fixed at the four corners of the lower surface of cover plate 16. Slots 18 are provided on the positioning rods 17. Positioning grooves 3 corresponding to positioning rods 17 are provided at the four corners of the top of processing box 12. Push blocks 31 are slidably provided at the bottom of positioning grooves 3. Springs 32 are connected between the lower surface of push blocks 31 and the inner wall of positioning grooves 3. Grooves 2 are provided in processing box 12 between two adjacent positioning grooves 3. Moving blocks 22 are slidably provided at both ends of grooves 2. Insert plates 221 are fixed at the end of moving blocks 22 near the adjacent groove 2 and insert plates 221 penetrate grooves 2 and are inserted into slots 18 on positioning rods 17.

[0018] A lead screw 21 is rotatably installed inside the groove 2, with the threads at both ends of the lead screw 21 being arranged in opposite directions. Movable blocks 22 at both ends of the groove 2 are respectively threaded into the two ends of the lead screw 21. By driving the lead screw 21 to rotate, the movable blocks 22 at both ends can be stably driven to move simultaneously. In this way, the movable blocks 22 at both ends of the groove 2 and the insert plate 221 can be controlled to simultaneously insert into or disengage from the positioning rod 17.

[0019] A rotating rod 23 is rotatably provided on the outer wall of the processing box 12 near the middle end of the lead screw 21. One end of the rotating rod 23 is inserted into the groove 2 and is connected to the lead screw 21 through two meshing bevel gears. A rotating wheel 24 is provided on the outer end of the rotating rod 23. The rotating wheel 24, in conjunction with the rotating rod 23, can quickly drive the lead screw 21 to rotate, making it convenient for the staff to directly control the rotation of the lead screw 21 from the outside and improving the ease of operation.

[0020] The rotating rod 23 is fixedly provided with a ring-shaped limiting strip 25. The rotating wheel 24 moves through the limiting strip 25. The side wall of the processing box 12 is provided with a limiting groove 27 corresponding to the rotating wheel 24. The rotating wheel 24 is inserted into the limiting groove 27. The limiting strip 25 allows the rotating wheel 24 to rotate together with the rotating rod 23 after it rotates. At the same time, the rotating wheel 24 can move on the rotating rod 23. After being inserted into the limiting groove 27, the rotating rod 23 will stop. Therefore, the rotating rod 23 will not be able to drive the lead screw 21 to rotate, thus ensuring the stop of the lead screw 21 and preventing the lead screw from backing up, which would cause the insert plate 221 to disengage from the positioning rod 17.

[0021] A protruding pull plate 26 is fixed on the side of the rotating wheel 24 away from the processing box 12. The pull plate 26 makes it convenient for the staff to pull the rotating wheel 24 away from the limiting groove 27, so that the staff can drive the rotating wheel 24 to rotate.

[0022] A rubber sealing ring 19 is fixedly provided on the lower surface of the cover plate 16 around the mounting block 15. A sealing groove 191 corresponding to the rubber sealing ring 19 is provided at the upper end of the treatment box 12. The rubber sealing ring 19 can seal the top of the filter assembly 14 to prevent leakage. At this time, the treatment box 12 can then perform normal filtration of tap water.

[0023] Working principle: During use, the water pipe is connected to the external water pipe through the input pipe 13 on the side wall of the treatment tank 12. The tap water to be used will first pass through the treatment tank 12 before entering the main body of the water dispenser 1. The treatment tank 12 is equipped with a filter assembly 14, which is composed of PP cotton, activated carbon and ultrafiltration membrane. After the tap water passes through the PP cotton, activated carbon and ultrafiltration membrane, bacteria, colloids and other substances in the water will be filtered. Then the filtered water will enter the main body of the water dispenser 1 through the inlet pipe 11. An additional filter assembly 14 is set on the outside of the main body of the water dispenser 1 in advance, thereby reducing the amount of filtration required by the filter element built into the main body of the water dispenser 1, thereby extending the service life of the filter element inside the main body of the water dispenser 1, thus indirectly reducing the frequency of replacement by the staff. Meanwhile, when the filter assembly 14 in the subsequent processing box 12 needs to be replaced after a period of use, the operator can pull the pull plate 26 to disengage the rotating wheel 24 from the limiting groove 27. At this time, the rotation of the rotating wheel 24 can drive the rotating rod 23 to rotate through the limiting strip 25, thereby causing the rotating rod 23 to drive the lead screw 21 to rotate in conjunction with the bevel gear. The moving blocks 22 threaded at both ends of the lead screw 21 will move towards each other simultaneously. In this way, the insert plate 221 fixed on the moving block 22 will disengage from the positioning groove 3 and the positioning rod 17. At the moment of disengagement, the spring 32 at the bottom of the positioning groove 3 will... Pushing the pusher 31 will move the positioning rod 17 upward, at which point the cover 16 will spring upward, making it easy for the staff to pull out the cover 16 directly. Then, the staff can remove the filter assembly 14 by pulling out the installation block 15 to complete the disassembly of the filter assembly 14. After replacing the filter assembly 14, the cover 16 will be placed on top of the treatment tank 12 to install the top of the treatment tank 12. The rubber sealing ring 19 can seal the top of the filter assembly 14 to prevent leakage. At this time, the treatment tank 12 can then filter tap water normally again.
