[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When the external brine filter is connected to the water inlet pipe through a pipeline, the clear liquid enters the water inlet pipe and flows into the clear liquid tank. Since the water level in the clear liquid tank is higher than the baffle, the clear liquid can automatically flow out from the outlet of the clear liquid tank, eliminating the possibility of air being entrained into the clear liquid pipeline, so as to ensure that the water can flow out smoothly.

[0014] 2. As the rotating rod rotates, the piston disk can be driven to move horizontally in the fixed cylinder, squeezing the gas in the fixed cylinder into the air bag. As the gas in the air bag increases, the volume increases, and the outer wall of the air bag contacts and fits with the inner wall of the water inlet pipe, thereby achieving a sealing effect on the water inlet pipe, preventing the liquid in the clear liquid tank from flowing back to the water inlet pipe when the external brine filter is not working.

[0015] 3. When the vertical plate moves downward, the inclined block is no longer squeezed. At this time, the turntable can rotate clockwise under the action of the torsion spring. When the turntable rotates, the first fan blade can be driven to rotate through the L-shaped rod. At this time, the first fan blade and the second fan blade are misaligned, thereby achieving a sealing effect on the water inlet pipe to prevent water from flowing back in the clear liquid tank, and at the same time, it can block the liquid in the brine filter from passing through the water inlet pipe.

[0016] 4. During the upward movement of the push plate, the semicircular block on the push plate at the lower side of the water inlet pipe will be limited by the pressure plate, and move up and down on the push plate and compress the second spring. As the semicircular block moves downward, it can drive the cleaning plate to rotate, and push the water on the push plate at the lower side of the water inlet pipe to the other side of the baffle plate and fall on the push plate at the lower side of the drain pipe, thereby facilitating the complete discharge of the liquid in the clear liquid tank.

[0017] 5. At the same time, when the rack plate moves downward, the ball first contacts the ground. When the ball is limited by the ground, the extrusion force of the rack plate moves downward and is converted into a driving force on the clear liquid tank, thereby pushing the clear liquid tank to rotate on the base through the disc and rotate to an inclined state. When the clear liquid tank flips from a vertical state to an inclined state, it is convenient to discharge all the water in the clear liquid tank through the drain pipe.

[0025] The drainage components include a push plate 24, a baffle 16, a closed cylinder 19, a connecting pipe 23, an air pressure component and a cleaning component.

[0027] The cleaning assembly includes a second spring 38, a semicircular block 39, a screw rod 25, and a cleaning plate 18. A groove is provided on the push plate 24. The semicircular block 39 is fixedly connected in the groove by the second spring 38. The screw rod 25 is fixedly connected to the semicircular block 39. The cleaning plate 18 is slidably connected to the push plate 24 and is threadedly connected to the screw rod 25. The thread spacing is large, so that when the semicircular block 39 moves downward, the cleaning plate 18 is limited by the push plate 24 and can rotate. At this time, the cleaning plate 18 can rotate on the push plate 24. A pressure plate 41 is fixedly connected to the upper end of the baffle 16. Two square blocks 36 are fixedly connected to the inner wall of the clear liquid tank 6. The square blocks 36 are arranged on both sides of the drain pipe 7.

[0028] Two sealing cylinders 3 are fixedly connected to the clear liquid tank 6, and the sealing cylinder 3 is sleeved on the rotating shaft 14. One end of the rotating shaft 14 has a plurality of blades 37 in a ring array. The blades 37 are arranged in the sealing cylinder 3, and circular holes are opened on the blades 37. The sealing cylinder 3 is filled with water. The rotating shaft 14 is provided with transverse teeth, and the rack plate 13 is meshed and connected with the rotating shaft 14.

[0029] In the present invention, when the external salt water filter is connected to the water inlet pipe 10 through a pipeline, the clear liquid enters the water inlet pipe 10 and flows into the clear liquid tank 6. Since the water level in the clear liquid tank 6 is higher than the baffle 16, the clear liquid can automatically flow out from the outlet of the clear liquid tank 6, thereby preventing the possibility of air being entrained into the clear liquid pipeline. When the external salt water filter is closed, the electromagnetic block 8 is turned on and has suction, which can have adsorption force on the metal block 9 on the upper side, thereby driving the metal block 8 and the C-shaped cavity 5 to move downward. The downward movement of the C-shaped cavity 5 can pull the vertical plate 11 and the rack plate 13 downward and compress the first spring 12. When the vertical plate 11 moves downward, it can drive the rotating rod 35 to rotate counterclockwise. Since the piston disc 32 can only move horizontally in the fixed cylinder 26, the rotation of the rotating rod 35 can drive the active The plug disc 32 moves horizontally in the fixed cylinder 26, squeezing the gas in the fixed cylinder 26 into the air bag 29. The volume of the air bag 29 increases with the increase of gas. The outer wall of the air bag 29 contacts and fits with the inner wall of the water inlet pipe 10, thereby achieving a sealing effect on the water inlet pipe 10, preventing the liquid in the clear liquid tank 6 from flowing back into the water inlet pipe 10. At the same time, when the vertical plate 11 moves downward, the inclined block 34 is no longer squeezed. At this time, the turntable 33 can rotate clockwise under the action of the torsion spring. When the turntable 33 rotates, it can drive the first fan blade 27 to rotate through the L-shaped rod 31. At this time, the first fan blade 27 and the second fan blade 28 are misaligned, thereby achieving a sealing effect on the water inlet pipe 10, preventing the water in the clear liquid tank 6 from flowing back, and at the same time blocking the liquid in the brine filter from passing through the water inlet pipe 10.

[0030] When the rack plate 13 moves downward with the C-shaped cavity 5, it can drive the shaft 14 to rotate. When the blade 37 rotates in the sealing cylinder 3 with the shaft 14, since the sealing cylinder 3 is filled with water and the diameter of the circular hole on the blade 37 is small, when the blade 37 moves in the sealing cylinder 3, the water on one side of the blade 37 flows to the other side through the circular hole. The water resistance can slow down the movement speed of the blade 37, thereby slowing down the rotation speed of the shaft 14, and preventing the rack plate 13 from moving downward quickly under the pulling force of the first spring 12. When the toggle plate 15 rotates with the shaft 14, it can flip from a horizontal state to a vertical state, thereby pushing the piston plate 22 to move in the cavity 4 and squeeze the internal gas into the two sealing cylinders 19. As the gas in the sealing cylinder 19 increases, the extrusion rod 40 can be pushed upward to squeeze The push plate 24 moves upward in the clear liquid tank 6, so that the two push plates 24 can push the liquid in the clear liquid tank 6 upward respectively. When the push plate 24 located at the lower side of the drain pipe 7 moves upward, the water is first limited by the square block 36 and no longer moves, and stays at the lower side of the drain pipe 7. At this time, the push plate 24 at the lower side of the water inlet pipe 10 continues to move upward. During the upward movement, the semicircular block 39 on the push plate 24 at the lower side of the water inlet pipe 10 is limited by the pressure plate 41, and moves up and down on the push plate 24 and compresses the second spring 38. As the semicircular block 39 moves downward, the cleaning plate 18 can be driven to rotate, and the water on the push plate 24 at the lower side of the water inlet pipe 10 can be pushed to the other side of the baffle 16 and fall on the push plate 24 at the lower side of the drain pipe 7, thereby facilitating the complete discharge of the liquid in the clear liquid tank 6.

[0031] At the same time, during the downward movement of the rack plate 13, the ball 21 first contacts the ground. When the ball 21 is limited by the ground, the squeezing force of the downward movement of the rack plate 13 is converted into a driving force on the clear liquid tank 6, thereby pushing the clear liquid tank 6 to rotate on the base 1 through the disc 2 and to be in an inclined state. Since the clear liquid tank 6 is flipped from a vertical state to an inclined state, it is convenient to discharge the water in the clear liquid tank 6 through the drain pipe 7.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
