Further, the circumferential groove 206a also has a guide surface 206d, and the guide surface 206d is used to guide the top 203b from a state of being located in the vibration section 206b and extending into the cavity 202a into the moving section 206 c.
In this embodiment, considering that when the top 203b of the vibration member 203 slides in the circumferential groove 206a, the vibration section 206b and the moving section 206c pass through, and only the vibration section 206b needs to slide normally when the vibration section 206c enters the moving section 206b, but whether the top 203b must slide into the moving section 206c or not needs to be considered when the vibration section 206b enters the moving section 206c, the guiding surface 206d is specially designed, so that the top 203b can slide well into the moving section 206c after certain energy, thereby realizing smooth transition and changing the occurrence of equipment failure.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
