[0025] Specifically, the mounting assembly 7 includes an external frame 71, a sealing end plate 73, a mounting port 74 and a fixing member 75. The periphery of the filter screen 6 is connected to the external frame 71. A sealing end plate 73 is provided at one end of the external frame 71. A mounting port 74 is provided on the side wall of the filter box 2 at a position corresponding to the sealing end plate 73. A fixing member 75 is provided between the filter box 2 and the sealing end plate 73.

[0026] By adopting the above technical solution, when the filter 6 needs to be cleaned, the fixing effect of the fixing member 75 on the sealing end plate 73 is first released, and then the sealing end plate 73 is moved toward the periphery of the installation opening 74. The movement of the sealing end plate 73 drives the external frame 71 to move away from the filter box 2 through the installation opening 74, and then the filter 6 inside the external frame 71 is cleaned, which is convenient for the operator to operate.

[0027] Specifically, the fixing member 75 includes a connecting spring 751, a connecting cavity 752, a side plate 753, a tightening screw 754, a push plate 755, a fixing groove 756 and a fixing rod 757. The interior of the filter box 2 and on both sides of the sealing end plate 73 are provided with a connecting cavity 752, the interior of the connecting cavity 752 is plugged with a fixing rod 757, a connecting spring 751 is connected between the connecting cavity 752 and the fixing rod 757, one end of the fixing rod 757 is connected to the pushing plate 755, the outer wall of the filter box 2 and on one side of the pushing plate 755 are connected, the interior of the side plate 753 is connected with a tightening screw 754, and the interior of the sealing end plate 73 is provided with a fixing groove 756 at the position corresponding to the fixing rod 757.

[0028] By adopting the above technical solution, the tightening screw 754 is rotated to rotate and move along the side plate 753. When the tightening screw 754 moves away from the push plate 755, the connecting spring 751 loses the external force and returns to its original state, driving the fixing rod 757 to move away from the fixing groove 756, thereby releasing the fixing effect of the fixing rod 757 on the sealing end plate 73.

[0029] Specifically, a support frame 72 is connected to the inner wall of the filter box 2 and is located below the external frame 71. Positioning protrusions are connected to both ends of the external frame 71 on one side close to the support frame 72. Positioning grooves are provided inside the support frame 72 at positions corresponding to the positioning protrusions.

[0030] By adopting the above technical solution, the external frame 71 is moved and inserted into the interior of the filter box 2, and is located above the support frame 72. At this time, the positioning protrusion is inserted into the positioning groove. Under the positioning action of the positioning protrusion and the positioning groove, the stability of the connection between the external frame 71 and the support frame 72 can be guaranteed. The support frame 72 can be used to support the external frame 71 to ensure the stability of the placement of the external frame 71.

[0031] When this embodiment is in use, the water inlet mechanism 3 is used to input the external water source into the external frame 71, and after multiple filtrations through the multi-layer filter screens 6, it falls into the filter box 2. The filtered water enters the sedimentation mechanism 1 for sedimentation, and then enters the water purifier body 5 for use. When it is necessary to clean the filter screen 6, the tightening screw 754 is rotated to make it rotate along the side plate 753. When the tightening screw 754 moves away from the push plate 755, the connecting spring 751 loses the external force and returns to its original state, driving the fixing rod 757 to move away from the fixing groove 756, and then moves the sealing end plate 73 toward the periphery of the installation opening 74. The movement of the sealing end plate 73 drives the external frame 71 to move away from the filter box 2 through the installation opening 74, and then the filter screen 6 inside the external frame 71 is cleaned, which is convenient for the operator to operate;

[0032] Example 2

[0033] The difference between this embodiment and embodiment 1 is that the primary filter assembly 9 includes an external connecting ring 91, a rotating rod 92, a filter cylinder 93 and an internal ring 94. The internal ring 94 is connected to the inner side wall of the joint 8. The filter cylinder 93 is arranged inside the internal ring 94. The rotating rod 92 is connected to the inner side wall of the filter cylinder 93. The external connecting ring 91 is connected to the outer side wall of the filter cylinder 93 and located on one side of the internal ring 94.

[0034] Specifically, a threaded ring is connected to one side of the external ring 91 close to the internal ring 94, a threaded groove is provided inside the internal ring 94 at a position corresponding to the threaded ring, and sealing rings are connected to the side walls of the external ring 91 and on both sides of the threaded ring.

[0035] By adopting the above technical solution, after the filter cylinder 93 is moved and inserted into the interior of the connector 8, the threaded ring is then inserted into the interior of the threaded groove. Then, the rotating rod 92 is held by hand and force is applied to drive the filter cylinder 93 to rotate. The rotation of the filter cylinder 93 drives the external ring 91 to rotate. The rotation of the external ring 91 drives the threaded ring to rotate and the thread is connected to the interior of the threaded groove, thereby facilitating the disassembly and assembly of the filter cylinder 93.

[0036] When this embodiment is used, the filter cylinder 93 is moved and inserted into the interior of the connector 8, and the threaded ring is then inserted into the interior of the threaded groove. Then, the rotating rod 92 is held by hand and force is applied to drive the filter cylinder 93 to rotate. The rotation of the filter cylinder 93 drives the external ring 91 to rotate. The rotation of the external ring 91 drives the threaded ring to rotate and is threadedly connected to the interior of the threaded groove. When the external water source is input into the interior of the filter box 2 using the water inlet mechanism 3, the external water source enters the interior of the filter cylinder 93 through the connector 8, and after being filtered by the filter cylinder 93, enters the interior of the water inlet mechanism 3, and then enters the interior of the external frame 71 for re-filtration operation, which is convenient for the initial filtration operation of the external water source and reduces the workload of the filter 6 inside the external frame 71.

[0037] The structure and principle of the sedimentation mechanism 1 composed of a sedimentation box, a water inlet pipe, a buffer inclined plate, a drain pipe, a drain hole, a cylinder, a piston column, a pull-out inner cavity plate, a sealing plate, a sealing gasket, a notch, a No. 2 pump, a suction pipe, and a discharge pipe in the present invention have been disclosed in a water purifier with multiple filtration disclosed in Chinese patent application No. 202322501330.6. Its working principle is: the top of the water purifier body 5 is fixedly connected to the sedimentation box, and a water inlet pipe that communicates with each other is fixedly connected to the sedimentation box. The inner walls on both sides of the water inlet pipe are fixedly connected with staggered buffer inclined plates. The other side of the sedimentation box is fixedly connected to the drain pipe. One end of the drain pipe passes through the bottom of the sedimentation box and communicates with the water purifier body 5. The drain pipe is located above the bottom of the sedimentation box and has a drain hole on its outer wall. The top side of the sedimentation box is fixedly connected to a cylinder above the drain pipe. The piston rod of the cylinder extending to the inside of the drain pipe is fixedly connected to the piston column. The drain pipe is fixedly connected to the drainpipe of the second pump, and the drain pipe is fixedly connected to the drainpipe of the second pump.

[0038] The structure and principle of the water inlet mechanism 3 composed of a No. 1 pump, an extension tube, a hose, and a winding drum mechanism in the utility model have been disclosed in a water purifier with multiple filtration disclosed in Chinese patent application No. 202322501330.6, and its working principle is: one side of the filter box 2 is fixedly connected to a No. 1 pump that is interconnected, one end of the No. 1 pump is fixedly connected to an extension tube, and a winding drum mechanism is fixedly connected to the top side of the bottom plate 4. A hose is wound on the winding drum mechanism, one end of the hose is fixedly connected to the extension tube and is interconnected, and the other end of the hose is connected to the extraction head 8. First, the hose is released by rotating the winding drum mechanism, and after docking with the extraction head 8 at the water source port, the No. 1 pump is started to draw the water source into the filter box 2.

[0039] The working principle and use process of the present invention are as follows: after the filter cartridge 93 is moved and inserted into the interior of the joint 8, the threaded ring is subsequently inserted into the interior of the threaded groove, and then the rotating rod 92 is held by hand to apply force to drive the filter cartridge 93 to rotate. The rotation of the filter cartridge 93 drives the external ring 91 to rotate, and the rotation of the external ring 91 drives the threaded ring to rotate and is threadedly connected to the interior of the threaded groove. When the water source from the outside is input into the interior of the filter box 2 by using the water inlet mechanism 3, the water source from the outside enters the filter cartridge 93 through the joint 8, enters the water inlet mechanism 3 after being filtered by the filter cartridge 93, and then enters the interior of the external frame 71 for re-filtration operation, which is convenient for the initial filtration operation of the external water source and reduces the workload of the filter 6 inside the external frame 71. The water source from the outside passes through the filter cartridge 93 After multiple filtrations, the multi-layer filter screen 6 falls into the filter box 2. The filtered water enters the sedimentation mechanism 1 for sedimentation, and then enters the water purifier body 5 for use. When the filter screen 6 needs to be cleaned, the tightening screw 754 is turned to rotate along the side plate 753. When the tightening screw 754 moves away from the push plate 755, the connecting spring 751 loses the external force and returns to its original state, driving the fixing rod 757 to move away from the fixing groove 756, and then moves the sealing end plate 73 to the periphery of the mounting port 74. The movement of the sealing end plate 73 drives the external frame 71 to move away from the filter box 2 through the mounting port 74, and then the filter screen 6 inside the external frame 71 is cleaned, which is convenient for the operator to operate.
