Abstract
This utility model discloses a kind of ultrasonic focusing energy transducer, comprises urceolus, connecting cylinder and wafer, and wherein one end of wafer is connected with the cavity bottom of described urceolus, and the other end is connected with described connecting cylinder, it is characterized in that, face is provided with interior trim ring on the wafer.The vibration that wafer pushed down by interior trim ring loosens, and promotes the elastic space of transducer wafer, and adds the Oscillation Amplitude of wafer, make the wafer of ultrasonic transducer can vibrate under a soft environment simultaneously, makes sealing silica gel be difficult to loosen.
Description
Technical field
This utility model relates to ultrasonic focusing energy transducer, is specifically related to a kind of medical ultrasonic focusing energy transducer.
Background technology
The medium connected in supersonic focus therapeutic process between human body skin and ultrasonic focusing energy transducer mainly degass water, needs transducer to immerse to degas in water, and ultrasonic energy totally tansitive is entered in human body.Transducer is to provide the key components being converted to acoustic energy by electric energy, and the inner necessary waterproof of transducer immerses, this just requires that ultrasonic focusing energy transducer possesses good water resistance, therefore in the good and bad life-span directly affecting ultrasonic focusing energy transducer of water resistance, the water proofing property of ultrasonic focusing energy transducer directly affects effectiveness in supersonic focus therapeutic simultaneously.Therefore good sealing property is had to be the performance directly affecting this ultrasonic transducer.The problem of sealing can be solved at present to a certain extent in similar ultrasonic focusing energy transducer, but its sealing property does not reach requirement, its present situation directly caused is that the ultrasonic transducer life-span is shorter, hermetically-sealed construction in current ultrasonic transducer mainly transducer wafer is directly intrinsic pressure at outer tube wall, then direct full-filling silica gel sealing inside urceolus.Effectively can solve the problem of sealing in short time, but due to ultrasonic focusing energy transducer be continuous vibration in the course of the work, the vibration of high frequency causes original sealing silica gel occur crack or come off, and brings serious threat to the performance of product.
Summary of the invention
Main purpose of the present utility model is to provide the ultrasonic focusing energy transducer that a kind of sealing is good, the life-span is long.
In order to realize utility model object, this utility model provides a kind of ultrasonic focusing energy transducer, comprises urceolus, connecting cylinder and wafer, and wherein one end of wafer is connected with the cavity bottom of described urceolus, the other end is connected with described connecting cylinder, and face is provided with interior trim ring on the wafer.
Preferably, two chamfers of described interior trim ring are pointed, and the interior chamfering of described chamfering becomes 60 ~ 70 degree with horizontal plane, and the outer chamfering of described chamfering becomes 50 ~ 65 degree with horizontal plane.
Preferably, the external diameter of described interior trim ring is slightly less than the diameter of wafer.
Preferably, the thickness of described interior trim ring is 8 ~ 12mm.
Preferably, the material of described interior trim ring be high conductivity, high rigidity, high stability, can the little metal material of deformation behavior.
This utility model is provided with interior trim ring by face on the wafer, the vibration that wafer pushed down by interior trim ring loosens, promote the elastic space of transducer wafer, and add the Oscillation Amplitude of wafer, make the wafer of ultrasonic transducer can vibrate under a soft environment simultaneously, make sealing silica gel be difficult to loosen.
Accompanying drawing explanation
Fig. 1 is ultrasonic focusing energy transducer sectional view in this utility model one embodiment.
The realization of this utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Detailed description of the invention
Should be appreciated that specific embodiment described herein only for explaining this utility model, and be not used in restriction this utility model.
With reference to Fig. 1, Fig. 1 is ultrasonic focusing energy transducer sectional view in this utility model one embodiment, in the present embodiment, ultrasonic focusing energy transducer comprises urceolus 1, connecting cylinder 2 and wafer 3, wherein one end of wafer 3 is connected with the cavity bottom of described urceolus 2, the other end is connected with described connecting cylinder 2, on described wafer 3, be provided with interior trim ring 4.
By being provided with interior trim ring 4 on described wafer 3, the vibration that wafer 3 pushed down by interior trim ring 4 loosens, promote the elastic space of transducer wafer 3, and add the Oscillation Amplitude of wafer 3, make the wafer 3 of ultrasonic transducer can vibrate under a soft environment simultaneously, make sealing silica gel be difficult to loosen.
Two chamfers of described interior trim ring 4 are pointed, and the interior chamfering of described chamfering becomes 60 ~ 70 degree with horizontal plane, and the outer chamfering of described chamfering becomes 50 ~ 65 degree with horizontal plane.Inside and outside chamfering is the lifting to the effective full-filling of sealing silica gel, and pointed chamfer design makes chamfering both sides all can realize enough full-filling silica gel spaces, ensure that the Oscillation Amplitude of transducer wafer 3 in vibration processes.
The external diameter of described interior trim ring 4 is slightly less than the diameter of wafer 3, and the external diameter of interior trim ring 4 is 90% ~ 95% of wafer 3 diameter.The thickness of described interior trim ring 4 is 8 ~ 12mm.The material of described interior trim ring 4 be high conductivity, high rigidity, high stability, can the little metal material of deformation behavior.
Interior trim ring 4 counterclockwise screws in ultrasonic ultrasonic focusing energy transducer, rotates to when wafer 3, then according to being rotated counterclockwise one week, the mode that dextrorotation is circled, and two weeks to guarantee that interior trim ring 4 fully contacts with wafer 3 back and forth.The probability impelling wafer 3 self-heating to loosen by the hold down gag of interior trim ring 4 reduces, the implantation of interior trim ring 4 makes ultrasonic transducer wafer 3 make surrounding effectively suppress in the course of the work, and be surrounding equably with wafer 3 close contact, making to vibrate is the vibration of a uniformity, can not be significantly vibrate in vibration processes, effective so loosening situation slowing down silica gel.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize this utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
