[0031] The above scheme is adopted: by pressing the pressing handle 82 downward, the pressing handle 82 pulls the limit bracket 83 upward through the vertical rod 81, and the limit bracket 83 pushes the first clamping block 61 and the second clamping block 62 to move upward synchronously. At the same time, the vertical rod 81 synchronously drives the gear shaft 7 to move upward, so that the first clamping block 61 and the second clamping block 62 release the lock on the hook 52, first remove the sealing block 51 at the bottom of the water inlet 3, so that the top of the connecting pipe 2 is connected to the outside, and then the impurities on the top of the impurity filter plate 11 can be removed. The impurities are cleaned out of the main shell 1, and then the clamping connection between the positioning block 101 and the positioning groove 102 is released, and the connecting pipe 2 is rotated to swap the positions of the impurity filter plates 11 at the bottom of the water inlet 3 and the water outlet 4. At this time, the sealing block 51 at the bottom of the water outlet 4 is removed, and the sealing block 51 on one side of the water inlet 3 is installed. The source water is transported from the water inlet 3 to flush out the impurities inside the impurity filter plate 11 at the bottom of the water outlet 4, and discharge them from the side of the main shell 1, thereby completing the cleaning of the impurity filter plate 11.

[0032] like Figure 2 , Figure 3 and Figure 5 As shown, the sealing block 51 corresponds to the positions of the water inlet 3 and the water outlet 4 respectively, the sealing block 51 is slidably connected to the main shell 1, and is in conflict with the top of the connecting pipe 2, and the inner side of the sealing block 51 is combined with the inside of the main shell 1 to form a sealed channel, and the diameter value is greater than the diameter value of the connecting pipe 2 and the water inlet 3.

[0033] The above scheme is adopted: by setting the sealing assembly 5, the sealing block 51 and the limiting slider 53 to seal the side of the main shell 1, when cleaning is needed, the sealing block 51 is removed, and the top of the connecting pipe 2 can be parallel to the outer edge of the main shell 1, so that the debris on the top of the impurity filter plate 11 can be cleaned out of the inside of the main shell 1, and then after the connecting pipe 2 is rotated, the impurity filter plates 11 at the bottom of the water inlet 3 and the water outlet 4 are swapped. At this time, the sealing block 51 at the bottom of the water outlet 4 is removed, and the sealing block 51 on one side of the water inlet 3 is installed, and then water can be transported from the water inlet 3 to flush out the impurities inside the impurity filter plate 11 at the bottom of the water outlet 4, so that they are discharged from the side of the main shell 1.

[0034] like Figures 3 to 6As shown, the fixing assembly 6 includes two groups of first clamping blocks 61 and second clamping blocks 62, and the first clamping blocks 61 and the second clamping blocks 62 are slidably connected to each other, the tops of the first clamping blocks 61 and the second clamping blocks 62 are both in contact with elastic push plates 63, and the ends of the first clamping blocks 61 and the second clamping blocks 62 that are close to each other are provided with teeth 64, the first clamping blocks 61 and the second clamping blocks 62 are distributed on the upper and lower sides of the gear shaft 7, the teeth 64 are meshed and connected with the gear shaft 7, the first clamping blocks 61 and the second clamping blocks 62 are both slidably connected to the inside of the main shell 1, the first clamping blocks 61 and the second clamping blocks 62 are respectively clamped with the corresponding hooks 52, and the top of the elastic push plate 63 is fixedly connected to the main shell 1 Then, the first clamping block 61 and the second clamping block 62 are provided with a bevel matching the hook 52 at a corner facing the hook 52, one end of the gear shaft 7 penetrates the main shell 1, and is provided with a handle and a one-way gear, the gear shaft 7 is slidably connected to the main shell 1, the elastic limit block 9 is slidably connected to the main shell 1, a spring is provided at the bottom of the elastic limit block 9, and at the same time, the top of the elastic limit block 9 is meshed with the one-way gear of the gear shaft 7. By setting the gear shaft 7 and the elastic limit block 9, the gear shaft 7 is limited by the elastic limit block 9, so that after the gear shaft 7 pulls the first clamping block 61 and the second clamping block 62 to close, the first clamping block 61 and the second clamping block 62 remain in a fixed state.

[0035] The above scheme is adopted: by setting a fixing component 6, the first clamping block 61 and the second clamping block 62 are respectively engaged with the hook 52, so as to fix a pair of sealing blocks 51, and the elastic push plate 63 is set, so that after the first clamping block 61 and the second clamping block 62 pass over the hook 52, the first clamping block 61 and the second clamping block 62 are pushed to reset, and the fixation of the hook 52 and the first clamping block 61 and the second clamping block 62 is completed, and the teeth 64 are set, and the first clamping block 61 and the second clamping block 62 are slidably connected to each other, so that the gear shaft 7 drives the first clamping block 61 and the second clamping block 62 to move closer to each other through the teeth 64, and the first clamping block 61 and the second clamping block 62 are slidably connected, so that when the hook 52 is pushed by the first clamping block 61 and the second clamping block 62 to move upward, the squeezed side will be pushed to flip with the gear shaft 7 as the axis, and tilt over the hook 52.

[0036] like Figures 3 to 5 As shown, when the sealing block 51 slides into the interior of the main shell 1, the hook 52 contacts the inclined surface of the first block 61, and the hook 52 squeezes and pushes the first block 61 to move upward, so that the first block 61 and the hook 52 are engaged, and then the gear shaft 7 pulls the first block 61 and the second block 62 closer to each other through the teeth 64, so that the sealing block 51 is pulled and squeezed to contact the main shell 1.

[0037] The above scheme is adopted: when the sealing block 51 slides into the interior of the main shell 1, the inclined surface on the hook 52 contacts the inclined surface of the first clamping block 61, and squeezes the first clamping block 61 to move upward, so that the first clamping block 61 is engaged with the hook 52, and then the first clamping block 61 and the second clamping block 62 are pulled together through the gear shaft 7, so as to fix the sealing block 51, make the sealing block 51 tightly contact with the main shell 1, and complete the sealing.

[0038] like Figure 3 , Figure 5 and Figure 6 As shown, the unlocking assembly 8 includes a vertical rod 81, a pressing handle 82 is slidably connected to the top of the vertical rod 81, and a limiting bracket 83 is fixedly connected to the bottom of the vertical rod 81; the vertical rod 81 is located in the middle of the gear shaft 7 and is rotatably connected to the gear shaft 7, the middle of the pressing handle 82 is rotatably connected to the main shell 1, and the limiting bracket 83 is located at the bottom of the first clamping block 61 and the second clamping block 62, and conflicts with the first clamping block 61 and the second clamping block 62. The pressing handle 82 pulls the limiting bracket 83 upward through the vertical rod 81, so that the limiting bracket 83 pushes the first clamping block 61 and the second clamping block 62 to move upward synchronously, so that the gear shaft 7 is disengaged from the elastic limiting block 9, the limit of the first clamping block 61 and the second clamping block 62 is released, and the hook 52 is disengaged from the first clamping block 61 and the second clamping block 62.

[0039] The above scheme is adopted: by setting an unlocking component 8, the vertical rod 81 drives the limiting bracket 83 to slide, so that the limiting bracket 83 pushes the fixing component 6 to move upward, and releases the fixing of the sealing component 5 by the fixing component 6. At the same time, the vertical rod 81 is rotatably connected with the gear shaft 7, so that the vertical rod 81 can drive the gear shaft 7 to move synchronously with the fixing component 6. The setting of the pressing handle 82 facilitates the lifting of the vertical rod 81 from the side. The setting of the elastic limiting block 9 can facilitate the fixing of the gear shaft 7, so that the gear shaft 7 remains in a fixed state after the first clamping block 61 and the second clamping block 62 are pulled together.

[0040] like Figure 1 and Figure 6 As shown, the positioning assembly 10 includes a positioning block 101 and a pair of positioning grooves 102. The positioning block 101 is rotatably connected to the main shell 1, and the positioning groove 102 is fixedly connected to the side of the connecting pipe 2. The upper end of the positioning block 101 abuts against a limiting push block 103. The middle part of the limiting push block 103 is movably connected with a positioning rod 104. The positioning block 101 is engaged with the positioning groove 102. The pair of positioning grooves 102 are located in the middle of the U-shaped pipe of the connecting pipe 2. The positioning block 101 is in the middle of the water inlet 3 and the water outlet 4. The positioning block 101 is engaged with the positioning groove 102, so that the connecting pipe 2 is connected to the main shell 1, and the channel opening remains in an overlapping state. The limiting push block 103 is slidably connected to the main shell 1, and the positioning rod 104 is engaged with the main shell 1.

[0041] The above scheme is adopted: by setting the positioning component 10, the positioning block 101 is engaged with the positioning groove 102, so as to position the communicating pipe 2, so that the communicating pipe 2 is connected with the main shell 1, and the channel openings remain overlapped to avoid staggered positions. By setting the positioning grooves 102 on both sides of the communicating pipe 2, the communicating pipe 2 can be positioned once every 180 degree rotation. By setting the limiting push block 103 and the locking rod 104, the limiting push block 103 limits the positioning block 101, so that the positioning block 101 is fixed.

[0042] The working principle and use process of the present invention are as follows: when cleaning is needed, the pressing handle 82 is pressed downward, so that the pressing handle 82 pulls the limit bracket 83 upward through the vertical rod 81, and the limit bracket 83 pushes the first block 61 and the second block 62 to move upward synchronously. At the same time, the vertical rod 81 synchronously drives the gear shaft 7 to move upward, so that the first block 61 and the second block 62 release the lock on the hook 52, first remove the sealing block 51 at the bottom of the water inlet 3, so that the top of the connecting pipe 2 is connected to the outside, and then the water inlet 3 can be cleaned. The debris on the top of the impurity filter plate 11 is cleaned out of the main housing 1, and then the clamping connection between the positioning block 101 and the positioning groove 102 is released, and the connecting pipe 2 is rotated to swap the positions of the impurity filter plates 11 at the bottom of the water inlet 3 and the water outlet 4. At this time, the sealing block 51 at the bottom of the water outlet 4 is removed, and the sealing block 51 on one side of the water inlet 3 is installed. The source water is transported from the water inlet 3 to flush out the impurities inside the impurity filter plate 11 at the bottom of the water outlet 4 and discharge them from the side of the main housing 1, thereby completing the cleaning of the impurity filter plate 11.
