[0030] Embodiment 1:

[0031] like Figure 1-5 As shown, it includes a first filter barrel 1, a second filter barrel 2 and a filter box 3. A water inlet pipe 12 is provided on the surface of the first filter barrel 1. Water enters the first filter barrel 1 through the water inlet pipe 12. The first filter barrel 1 and the second filter barrel 2 are connected through a first pipe 4. The water in the first filter barrel 1 enters the second filter barrel 2 through the first pipe 4. The second filter barrel 2 and the filter box 3 are connected through a second pipe 41. The water in the second filter barrel 2 enters the filter box 3 through the second pipe 41. The bottom of the filter box 3 away from the second filter barrel 2 is fixedly connected with a water outlet pipe 36. The water in the filter box 3 is discharged through the water outlet pipe 36. The first pipe 4 and the second pipe 41 are both provided with a booster pump 42 to increase the flow rate of water.

[0032] The two sides of the inner wall of the filter box 3 are fixedly connected with the corresponding first clamping plates 31, and the two sides of the inner wall of the filter box 3 are slidably connected with the corresponding second clamping plates 32. By sliding the second clamping plates 32, the spacing between the first clamping plates 31 and the second clamping plates 32 can be adjusted. The two sides of the inner wall of the filter box 3 are provided with sliding grooves 33, and one side of the second clamping plate 32 is fixedly connected with a slider 321. The slider 321 is slidably connected in the sliding groove 33, and the slider 321 passes through the side wall of the filter box 3 and protrudes from the outside of the filter box 3. The positions corresponding to the sliding grooves 33 on both sides of the outer wall of the filter box 3 are fixedly connected with sealing boxes 34. The sealing box 34 covers the sliding grooves 33 and the slider 321 to prevent water in the filter box 3 from flowing out of the sliding grooves 33. The interior of the sealing box 34 is rotatably connected with a screw 35, and both ends of the sealing box 34 are fixedly connected with sealing bearings 39. The screw 35 is rotatably connected to the sealing box 34 through the sealing bearings 39. The inner wall of the sealing box 34 is fixedly connected with a partition 38, such as Figure 2-3 As shown, the partition 38 divides the multiple chutes 33, so as to prevent the water in the filter box 3 from flowing in the sealing box 34 and circulating through the multiple chutes 33, resulting in the problem that the water is discharged without being fully filtered. The screw 35 is rotatably connected in the partition 38, and a sealing bearing 39 is fixedly connected in the partition 38. The screw 35 is rotatably connected to the partition 38 through the sealing bearing 39. A threaded hole 322 is opened on one side of the slider 321. The slider 321 is threadedly connected to the outer surface of the screw 35 through the threaded hole 322. By rotating the screw 35, it is rotated in the threaded hole 322, so that the screw 35 can be passed. The second clamping plate 32 is moved by the slider 321, and a fixing frame 6 is clamped between the first clamping plate 31 and the second clamping plate 32. A semi-permeable filter membrane 61 is fixedly connected inside the fixing frame 6. A cover plate 5 is fixedly installed on the top of the filter box 3. Fixed blocks 51 are fixedly connected at the four corners of the cover plate 5. Positioning blocks 37 are fixedly connected at the four corners of the top of the filter box 3. Through holes are provided on the fixing blocks 51 and the positioning blocks 37. By using bolts to pass through the through holes and threading nuts on the bolt surfaces, the cover plate 5 can be fixedly installed above the filter box 3 to achieve sealing of the top of the filter box 3.

[0033] Embodiment 2:

[0034] like Figure 1 , Figure 2 and Figure 6As shown, on the basis of Example 1, a first supporting ring 11 is fixedly connected to the inner wall of the first filter barrel 1, a water filter 7 is overlapped on the top of the first supporting ring 11, and the first supporting ring 11 supports the water filter 7, a second supporting ring 21 is fixedly connected to the inner wall of the second filter barrel 2, a hydrogen ion exchange resin filter 8 is overlapped on the top of the second supporting ring 21, and the second supporting ring 21 supports the hydrogen ion exchange resin filter 8, and the tops of the first filter barrel 1 and the second filter barrel 2 are both threadedly connected with a sealing cover 9, and the sealing cover 9 is used to seal the tops of the first filter barrel 1 and the second filter barrel 2.

[0035] Specifically, the water filter 7 includes a first filter cartridge 71, a filter assembly 72 is disposed inside the first filter cartridge 71, and the filter assembly 72 includes a quartz sand filter filling layer, a sponge filter filling layer and an activated carbon filter filling layer;

[0036] The hydrogen ion exchange resin filter 8 includes a second filter cartridge 81, and a hydrogen ion exchange resin filter filling layer 82 is arranged inside the second filter cartridge 81. The hydrogen ion exchange resin reacts with part of the calcium and magnesium ions in the water to appropriately reduce the hardness;

[0037] The edges of the tops of the first filter cartridge 71 and the second filter cartridge 81 are fixedly connected with a support rod 781, the top of the support rod 781 is fixedly connected with a pressure ring 782, the bottom of the sealing cover 9 is fixedly connected with a threaded ring 91, and the top of the sealing cover 9 is fixedly connected with a handle 92. After the sealing cover 9 is threadedly connected to the top of the first filter barrel 1 through the threaded ring 91, the threaded ring 91 provides downward pressure on the pressure ring 782, so that the bottom of the first filter cartridge 71 can fit tightly with the top of the first support ring 11, thereby ensuring the sealing. When the sealing cover 9 is threadedly connected to the top of the second filter barrel 2, the same principle as above can ensure the sealing between the bottom of the second filter cartridge 81 and the second support ring 21.

[0038] The working principle of the utility model is as follows: when replacing the semipermeable filter membrane 61, after removing the cover plate 5, use a wrench to rotate the screw rod 35 to make it rotate in the threaded hole 322, thereby driving the slider 321 to move, so that the second clamping plate 32 is away from the fixed frame 6, thereby loosening the fixed frame 6, and the semipermeable filter membrane 61 can be easily taken out. Since the spacing between the second clamping plate 32 and the first clamping plate 31 is greater than the width of the fixed frame 6, the new semipermeable filter membrane 61 can be easily inserted between the first clamping plate 31 and the second clamping plate 32. At this time, use a wrench to rotate the screw rod 35 again, so that the second clamping plate 32 is close to the fixed frame 6, and cooperates with the first clamping plate 31 to tightly clamp the fixed frame 6 to achieve sealing of the side of the semipermeable filter membrane 61, thereby saving manpower when disassembling and assembling the semipermeable filter membrane 61.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] 1. Use a wrench to rotate the screw 35 so that the distance between the second clamping plate 32 and the first clamping plate 31 is larger than the width of the fixed frame 6, so that when replacing the semi-permeable filter membrane 61, the fixed frame 6 can be easily inserted or pulled out from between the first clamping plate 31 and the second clamping plate 32. After replacing the semi-permeable filter membrane 61, use a wrench to rotate the screw 35 again so that the second clamping plate 32 is close to the fixed frame 6, and cooperates with the first clamping plate 31 to tightly clamp the fixed frame 6 to achieve sealing of the side of the semi-permeable filter membrane 61, which can achieve the purpose of saving time and effort.

[0041] 2. By setting the filter component 72 in the first filter cartridge 71, opening the sealing cover 9, and pulling the first filter cartridge 71 out of the first filter barrel 1, the filter component 72 can be replaced. By setting the hydrogen ion exchange resin filter filling layer 82 inside the second filter cartridge 81, opening the sealing cover 9, and pulling the second filter cartridge 81 out of the second filter barrel 2, the exchange resin filter filling layer 82 can be replaced, thereby achieving the purpose of facilitating the replacement of the water quality filter 7 and the hydrogen ion exchange resin filter 8.

[0042] 3. By fixing the support rod 781 on the top of the first filter cartridge 71 and the second filter cartridge 81, and fixing the pressure ring 782 on the top of the support rod 781, when installing the sealing cover 9, the threaded ring 91 at the bottom of the sealing cover 9 can provide downward pressure to the pressure ring 782, thereby ensuring the sealing between the first filter cartridge 71 and the first support ring 11, and the sealing between the second filter cartridge 81 and the second support ring 21, and the support rod 781 will not block the entrance of the first filter barrel 1 or the second filter barrel 2, thereby improving practicality.
