[0032] like Figures 1-6As shown, this embodiment proposes a pneumatic high-frequency vibrator structure, including a base 1 and a top cover 2. The top cover 2 is bolted to the top of the base 1. A rotating shaft 13 is fixedly connected inside the base 1. A vibrating plate 14 is rotatably connected to the rotating shaft 13 and rotates on the rotating shaft 13. A driving protrusion 15 is fixedly installed on the top of the vibrating plate 14. A switching lever 16 is rotatably connected to the rotating shaft 13 and rotates on the rotating shaft 13. The switching lever 16 has two first air inlets 17. An arc-shaped groove 18 is formed on the switching lever 16. An L-shaped air inlet channel 21 is formed inside the top cover 2. The top cover 2 also has an L-shaped air inlet channel 21. The upper cover 2 has a first fan-shaped groove 25 at the bottom of the exhaust channel 23. The inner wall of the first fan-shaped groove 25 has a second air inlet 22, which is connected to the L-shaped air inlet channel 21. Gas enters the second air inlet 22 from the L-shaped air inlet channel 21 and then enters the first air inlet 17. The inner wall of the first fan-shaped groove 25 also has a fan-shaped exhaust groove 24, one end of which is connected to the L-shaped exhaust channel 23. Gas enters the L-shaped exhaust channel 23 from the fan-shaped exhaust groove 24 and is finally discharged. This vibrator not only has multiple installation methods and adjustable air inlet direction, but also has the advantages of controllable vibration direction, small size, low starting air pressure, low air consumption, and high vibration frequency.

[0033] An air inlet 27 is provided at one end of the L-shaped air intake channel 21. An external air source is connected to one of the air inlets 27 according to the actual use, and the other air inlet 27 is blocked with an air plug screw.

[0034] A muffler sleeve 28 is installed at one end of the L-shaped exhaust channel 23 to reduce noise during exhaust.

[0035] The drive protrusion 15 slides within the arc-shaped groove 18, and the switching paddle 16 is located within the first sector-shaped groove 25. The vibrating plate 14 drives the drive protrusion 15, and the drive protrusion 15 drives the switching paddle 16.

[0036] A second sector-shaped groove 12 is provided on the base 1. The vibrating plate 14 is located in the second sector-shaped groove 12. The vibrating plate 14 swings in the second sector-shaped groove 12. The air pressure pushes the vibrating plate 14 to rotate instantaneously and hit the inner cavity side wall of the second sector-shaped groove 12 on the base 1.

[0037] The base 1 has a sealing groove 19, and the bottom of the top cover 2 is glued with a sealing strip 26. The sealing effect is better after the top cover 2 is connected to the base 1. During use, sealing strips, sealant or other sealing structures can be selected for sealing according to the actual situation.

[0038] The base 1 has internal threads 3 on the front and side walls. The vibrator is installed according to the required vibration direction. During use, the installation method of the vibrator can be determined according to the actual situation, and is not limited to using a screw to connect with the internal threads 3.

[0039] Specifically, when using this pneumatic high-frequency vibrator: Install the vibrator according to the required vibration direction using a screw with internal thread 3. Connect one of the air inlets 27 to an external air source, and then plug the other air inlet 27 with an air plug screw. When the external air source supplies air into the air inlet 27, the gas enters the L-shaped air intake channel 21. The gas then enters the second left air inlet 22 (which corresponds to the first left air inlet 17) from the L-shaped air intake channel 21. Next, the gas enters the second sector groove 12 through the first air inlet 17, thus pushing the vibrating plate 14. The vibrating plate 14 then... The drive protrusion 15 drives the switching lever 16 (the vibrating plate 14 swings left and right, delaying the switching lever 16 to swing left and right); when the left first air inlet 17 is inlet, the right first air inlet 17 is blocked by the switching lever 16. At this time, the left side of the fan-shaped exhaust groove 24 is closed and the right side is open. The air pressure pushes the vibrating plate 14 to rotate instantaneously and hit the inner wall of the second fan-shaped groove 12 on the base 1 (at this time, the right second air inlet 22 corresponds to the right first air inlet 17). When the vibrating plate 14 hits the base 1, the left first air inlet 17 is blocked and the right first air inlet 17 is opened. At the same time, the fan-shaped exhaust groove 24 changes state to realize reciprocating cyclic swinging.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
