When the forked rod (45) moves upward, it will drive the baffle (48) to move upward. When the baffle (48) moves upward, it will seal the air intake block (47). When the baffle (48) moves upward, it will drive the piston plate (410) to move upward. When the piston plate (410) moves upward, the bottom of the connecting frame (49) will draw in air from the air exchange port. After the arc block (44) separates from the forked rod (45), the gas inside the connecting frame (49) can only be discharged from the through hole of the cover plate (411) because the cover plate (411) cannot rotate. This can reduce the speed at which the gas inside the connecting frame (49) is discharged, thus reducing the speed at which the baffle (48) descends.

2. The automatic spraying device for porcelain insulators according to claim 1, characterized in that: A torsion spring is provided between the extrusion plate (33) and the fixing plate (32), and the circular frame (34) is in contact with the extrusion plate (33).

3. An automatic spraying device for porcelain insulators according to claim 2, characterized in that: A hollow frame (36) is fixedly installed on the surface of the base (31), a sealing frame (39) is fixedly installed on the top of the hollow frame (36), a sealing plate (310) is slidably installed inside the sealing frame (39), the top of the sealing plate (310) is fixed to the circular frame (34) by a linkage rod (311), and a jet frame (312) is fixedly installed on the top of the hollow frame (36).

4. An automatic spraying device for porcelain insulators according to claim 3, characterized in that: The surface of the connecting block (43) is provided with an adjustment component, which includes an L-shaped frame (51), a spray nozzle (52) and a circular rod (53). The L-shaped frame (51) is fixed to the connecting block (43) by an elastic telescopic connecting rod. The spray nozzle (52) is rotatably mounted on the surface of the L-shaped frame (51).
