[0031] As a technical optimization scheme of the present utility model, by setting the magnetic plate 13, when the user first moves the first connecting block 7 into the guiding groove 4, the magnetic plate 13 can initially adsorb the first connecting block 7 in the guiding groove 4, so that the first mounting plate 5 will not move automatically, thereby achieving the effect of facilitating the user to install the filter plate 3.

[0032] Reference Figure 2 , a first baffle 14 is fixedly connected to the inner side of the limiting rail 101, a second baffle 15 is fixedly connected to the outer side of the limiting rail 101, the outer side of the first baffle 14 is movably connected to the inner side of the limiting block 102, and the inner side of the second baffle 15 is slidably connected to the inner wall of the limiting block 102.

[0033] As a technical optimization solution of the present utility model, by providing the first baffle 14 and the second baffle 15, when the limiting block 102 moves towards the inner side of the limiting rail 101, the first baffle 14 can be used to limit the final moving distance of the limiting block 102 towards the inner side. When the limiting block 102 moves towards the outer side of the limiting rail 101, the second baffle 15 can be used to limit the final moving distance of the limiting block 102 towards the outer side, thereby achieving the effect that the limiting block 102 does not move out of the limiting rail 101.

[0036] Working principle and usage process of the present utility model: When the user needs to replace the filter plate 3, first unscrew the bolts at the connection groove 11 and the limit groove 12, so that the limit block 102 is no longer connected to the housing 1. Then move the limit block 102 towards the inside of the limit rail 101. The first baffle 14 can limit the final moving distance of the limit block 102 towards the inside. Then, by using multiple auxiliary strips 16, the friction between the user and the limit block 102 can be increased, facilitating the user to move the limit block 102 and avoiding the situation where the user's hand slips and it is not convenient to move the limit block 102. Then take out the first mounting plate 5 and the second mounting plate 6, separate the first mounting plate 5 from the second mounting plate 6, take out the filter plate 3 to be replaced, place the new filter plate 3 into any one of the mounting grooves 91 inside the first mounting plate 5 or the second mounting plate 6. The mounting groove 91 can preliminarily fix the filter plate 3. Then, by using the magnetic strip 92, the second mounting plate 6 and the second mounting plate 6 can be connected, making the installation of the filter plate 3 more stable. Then align the back of the first connecting block 7 with the guiding groove 4 and move the first connecting block 7 into the guiding groove 4. The magnetic plate 13 can preliminarily adsorb the first connecting block 7 in the guiding groove 4, preventing the first mounting plate 5 from moving automatically. When the user moves the first connecting block 7 and the second connecting block 8 into the guiding groove 4, move the limit block 102 towards the outside of the limit rail 101, so that the limit block 102 completely covers the guiding groove 4. The limit block 102 can prevent the second connecting block 8 from moving out of the guiding groove 4, avoiding the situation where the second connecting block 8 and the first connecting block 7 move out of the guiding groove 4. When the limit block 102 completely covers the guiding groove 4, align the connection groove 11 with the limit groove 12, and use bolts to connect the connection groove 11 and the limit groove 12, fixing the limit block 102 to the housing 1, and further making the limit block 102 unable to move left and right, thus achieving the effect of facilitating installation and replacement.

[0037] In summary: For this high-efficiency filter that facilitates the replacement of the filter mesh, by setting the first mounting plate 5 and the second mounting plate 6, the filter mesh can be fixed inside the housing 1 by the cooperation of the first mounting plate 5 and the second mounting plate 6. Then, by separating the second mounting plate 6 from the first mounting plate 5, the filter plate 3 can be removed, solving the problem that during long-term use of the filter mesh, it is prone to aging, which will affect the filtration quality and increase the energy consumption of the machine. Since this filter does not have a device that facilitates disassembly and replacement, it is not convenient for the user to replace, thus reducing the replacement efficiency of the filter mesh.
