Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of an easily adjustable visual piston-type flow switch, comprising a switch body 1, a mounting plate 2 fixedly connected to the side wall of the switch body 1, a small motor 3 fixedly connected to the side wall of the mounting plate 2, a drive wheel 6 fixedly connected to the output end of the small motor 3 via a rotating shaft, a rotating groove 5 formed on the outer wall of the switch body 1, a groove 4 formed on the inner wall of the switch body 1, a driven wheel 7 rotatably connected to the inner wall of the rotating groove 5, the driven wheel 7 being sleeved on the inlet port of the switch body 1, a locking block 8 fixedly connected to the side wall of the driven wheel 7, a main filter plate 10 attached to the side wall of the driven wheel 7, a fixing hole 9 formed through the surface of the main filter plate 10, a secondary filter plate 11 provided on the side wall of the main filter plate 10, the main filter plate 10 and the secondary filter plate 11 having the same number of filter holes on their surfaces, capable of filtering the flowing medium, and a disassembly assembly provided on the surface of the secondary filter plate 11.

[0033] Reference Figure 3 - Figure 5 The groove 4 is fitted on the outer wall of the drive wheel 6. The groove 4 provides space for the drive wheel 6 to contact the driven wheel 7. The drive wheel 6 and the driven wheel 7 mesh with each other. The inner wall of the fixing hole 9 is inserted into the outer wall of the locking block 8. The disassembly assembly includes a rotating rod 12. The end of the rotating rod 12 is rotatably connected to the outer wall of the switch body 1. The outer wall of the rotating rod 12 is fixedly connected to a limit plate 13. The inner wall of the limit plate 13 is threaded with a bolt 15. The outer wall of the bolt 15 is threaded with the inner wall of the screw hole 14. The surface of the auxiliary filter plate 11 is provided with screw holes 14. There are four sets of disassembly assemblies. The four sets of disassembly assemblies are distributed in a rectangular array with the center point of the entry end of the switch body 1 as the axis of symmetry.

[0034] Reference Figure 3 and Figure 5 A protective shell 16 is hinged to the outer wall of the switch body 1. The protective shell 16 is fitted onto the outer wall of the drive wheel 6. A recessed handle 19 is provided on the outer wall of the protective shell 16. A plug rod 18 is fixedly connected to the outer wall of the protective shell 16. The outer wall of the plug rod 18 is adapted to the inner wall of the socket 17. The outer wall of the switch body 1 has a socket 17. The protective shell 16 can be fitted onto the outer wall of the drive wheel 6, the mounting plate 2 and the small motor 3 to provide protection and shielding. The protective shell 16 is fixed to the switch body 1 by inserting the plug rod 18 into the socket 17.

[0035] Working principle: The main filter plate 10 and the auxiliary filter plate 11 cover the inlet port of the switch body 1 to filter the flowing medium. When the flow rate needs to be adjusted, the small motor 3 is started. The small motor 3 slowly drives the rotating shaft to rotate, causing the drive wheel 6 to rotate, which in turn causes the driven wheel 7 to drive the main filter plate 10 to rotate. When the main filter plate 10 rotates, the filter holes on its surface can intersect with the filter holes on the surface of the auxiliary filter plate 11, thereby adjusting the degree of filtration. When it is necessary to remove the main filter plate 10 and the auxiliary filter plate 11, first reverse the bolts 15 one by one. Twisting, the bolt 15 gradually unscrews from the screw hole 14. After the bolt 15 is removed from the screw hole 14, the limiting plate 13 is pried open, causing it to drive the rotating rod 12 to rotate. After the limiting plate 13 is no longer covering the surface of the auxiliary filter plate 11, it is removed. A set of locking blocks 8 are manually pressed inward, so that the tops of the locking blocks 8 come together. Then, force is applied to the main filter plate 10 to make the fixing hole 9 disengage from the locking blocks 8, thereby removing the main filter plate 10 and the auxiliary filter plate 11 from the switch body 1, improving the cleanliness of the flow medium controlled by the switch body 1.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
