Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides a low water level filtering device, including a filtering device body 1, an inner cavity of the filtering device body 1 is movably clamped with a filter cartridge 2, the top of the filtering device body 1 is movably mounted on a reinforcement frame 3 outside the filter cartridge 2, a clamping block 4 is fixedly mounted on the inner side of the reinforcement frame 3, a first clamping block 8 located on the inner wall of the filter cartridge 2 is fixedly mounted in the middle of the inner side of the clamping block 4, a first air groove 10 is opened at the front and rear sides of the inside of the right side of the clamping block 4, a first piston cylinder 11 is movably mounted in the inner cavity of the first air groove 10, a top block 9 is fixedly mounted on the left end of the first piston cylinder 11, a second air groove 13 is opened in the inside of the right side of the clamping block 4 at the right end of the inner side of the first air groove 10, a second piston rod 14 is movably mounted in the inner cavity of the second air groove 13, and the left side of the second piston rod 14 is fixedly mounted with the inside of the left clamping block 4.

[0021] When the reinforcement frame 3 and the clamping block 4 are pushed toward each other, the two clamping blocks 4 will fit together, and the top block 9 will push the first piston cylinder 11 to move rightward in the inner cavity of the first air groove 10, thereby causing the air pressure in the first air groove 10 and introduced into the inner wall of the second air groove 13 through the connecting groove 15, thereby increasing the air pressure on the inner wall of the second air groove 13 and driving the second piston rod 14 and the arc block 12 to be inserted to the left as a whole into the interior of the left clamping block 4.

[0022] like Figure 2 and Figure 5 As shown, a limiting rod 5 located below the middle of the outer side of the reinforcement frame 3 is fixedly installed on the top of the filter device body 1, and a sliding block 6 located on the surface of the limiting rod 5 is fixedly installed in the middle of the outer bottom end of the reinforcement frame 3, and the surface of the limiting rod 5 and the inner wall of the sliding block 6 are slidably connected.

[0023] By adopting the above solution, by setting the limit rod 5, when the reinforcement frame 3 and the clamping block 4 move toward or away from each other as a whole, the slider 6 will slide along the surface of the limit rod 5 to limit the movement of the reinforcement frame 3 and the clamping block 4.

[0024] like Figure 5 As shown, a first spring 7 is fixedly mounted on the inner side of the slider 6 , and the other end of the first spring 7 is fixedly connected to the inner wall of the filter device body 1 .

[0025] By adopting the above scheme, by providing the first spring 7, when the two reinforcement frames 3 and the clamping block 4 are pushed towards each other and fixed, the first spring 7 can be compressed towards each other as a whole, and then when the reinforcement frame 3 and the clamping block 4 are released, the elastic force of the first spring 7 will be released, so that the pushing slider 6 can be smoothly driven to drive the reinforcement frame 3 and the clamping block 4 to move and reset as a whole.

[0026] like Figure 4 As shown, a connecting groove 15 is provided inside the clamping block 4 and is located between the right sides of the first air groove 10 and the second air groove 13 , and both ends of the connecting groove 15 are connected to the right sides of the first air groove 10 and the second air groove 13 , respectively.

[0027] By adopting the above solution and providing the connecting groove 15 , when the top block 9 pushes the first piston cylinder 11 to move rightward, the gas in the inner cavity of the first gas groove 10 will be pushed through the connecting groove 15 and introduced into the interior of the second gas groove 13 .

[0028] like Figure 5 As shown, a push block 18 is fixedly installed on the right side of the top of the second piston rod 14 , and the top end of the push block 18 passes through the clamping block 4 .

[0029] By adopting the above solution, by providing a push block 18, the operator can drive the two second piston rods 14 to move rightward by pushing the two push blocks 18, so that the second piston rod 14 is disengaged from the inside of the left clamping block 4, thereby releasing the fitting and fixing effect between the two clamping blocks 4.

[0030] like Figure 3 and 5 As shown, a second clamping block 16 located outside the filter cartridge 2 is movably installed at the front and rear sides of the interior of the reinforcement frame 3, and the top of the second clamping block 16 is in the shape of an inclined surface.

[0031] By adopting the above solution, by providing the second clamping block 16 , when the filter cartridge 2 is inserted downward into the filter device body 1 , the outer portion of the filter cartridge 2 will squeeze and push the inclined surface of the second clamping block 16 to drive the second clamping block 16 to retract into the reinforcement frame 3 .

[0032] like Figure 5 As shown, a second spring 17 is fixedly mounted on the outer side of the second clamping block 16 , and the other end of the second spring 17 is fixedly connected to the inner wall of the reinforcement frame 3 .

[0033] By adopting the above scheme, a second spring 17 is provided. When the second clamping block 16 is pushed by the filter cartridge 2 to retract into the reinforcement frame 3, the second spring 17 will be compressed until the second clamping block 16 is directly aligned with the notch on the outer side of the filter cartridge 2. Then, the elastic force of the second spring 17 can be released to push the second clamping block 16 toward each other so that the inner end is clamped in the notch of the filter cartridge 2, thereby smoothly reinforcing the filter cartridges 2 on both sides.

[0034] The working principle and use process of this utility model:

[0035] First, the operator can insert the filter cartridge 2 from the middle of the filter device body 1, and then push the two reinforcement frames 3 and the clamping block 4 to move toward each other, so that the top block 9 in the right clamping block 4 is pushed to drive the first piston cylinder 11 to slide to the right in the inner cavity of the first gas groove 10. At this time, the first piston cylinder 11 will push the gas at the right end of the inner cavity of the first gas groove 10 through the connecting groove 15 to the inner wall of the second gas groove 13, thereby increasing the gas pressure in the inner cavity of the second gas groove 13, and then will push the second piston rod 14. The arc block 12 moves to the left as a whole, so that the second piston rod 14 is inserted into the inner wall of the clamping block 4 on the left, and the two reinforcement frames 3 and the clamping block 4 can be smoothly fixed together as a whole. At the same time, the two first clamping blocks 8 on the inner sides of the two clamping blocks 4 are clamped in the inner wall of the groove of the middle filter cylinder 2 to reinforce the middle filter cylinder 2, and then the filter cylinders 2 on both sides are inserted respectively, so that the second clamping blocks 16 are first back to back, and then pushed by the elastic force of the second spring 17 to clamp in the outer groove of the filter cylinder 2, so as to realize the reinforcement of the filter cylinders 2 on both sides.

[0036] Then, when the operator needs to remove the filter cartridge 2, the two push blocks 18 can be pushed to drive the second piston rod 14 to move to the left as a whole, so that the second piston rod 14 is separated from the inner wall of the left clamping block 4, and the fitting and fixing effect on the reinforcement frame 3 and the clamping block 4 is released, and finally the elastic force of the first spring 7 is released, so that the two sliders 6 and the reinforcement frame 3 and the clamping block 4 can be smoothly driven to move in opposite directions, thereby releasing the reinforcement effect on the filter cartridge 2, and then the filter cartridge 2 can be smoothly removed.
