Abstract
The embodiment of the invention relates to an ultrasonic transducer, comprising a shell, an emitter arranged at the top of the shell, a rear-end mass block arranged at the bottom inside the shell and a piezoelectric element fixed between the emitter and the rear-end mass block by a bolt, wherein the emitter comprises a working part with a spherical convex top surface. The ultrasonic transducer has the following beneficial effects: the transducer can be directly contacted with the human body without using a stainless steel plate for conduction, thus avoiding energy loss caused by conduction and giving full play to the ultrasonic power; the transducer has the advantages of wider working frequency bandwidth, concentrated ultrasonic energy and uniform strength; an electrodeless ceramic wafer is arranged between every two piezoelectric ceramic wafers, and loops can not be formed even if short circuit caused by burst of the piezoelectric ceramic wafers happens, thus effectively avoiding the human body from possible electric shock due to contact.
Description
Technical field
The present invention relates to a kind of ultrasonic unit, relate in particular to a kind of ultrasonic transducer.
Background technology
Ultrasonic transducer is the critical component that in supersonic wave cleaning machine and the cleaning equipment piezo-electric effect is converted to the mechanical energy vibrations.Existing ultrasonic transducer is made of mass, emitting head, piezoelectric element etc., and the end face of emitting head is a horizontal plane, and this transducer all needs to do conduction by corrosion resistant plate, be not suitable for the human body contact, and its operational frequency bandwidth is narrower, and ultrasonic effect is inhomogeneous, the ultrasonic wave effect a little less than; Piezoelectric element in the existing transducer is made up of a slice piezoelectric chip at least, can form the loop when short circuit, has caused Danger Electric shock risk.
Summary of the invention
Embodiment of the invention technical problem to be solved is, a kind of ultrasonic transducer is provided, and ultrasonic energy is concentrated, and intensity is even.
The further technical problem to be solved of the present invention is that a kind of ultrasonic transducer is provided, and it can avoid the electric shock accidents that leaks electricity.
For solving the problems of the technologies described above, a kind of ultrasonic transducer is provided, comprise housing, be arranged at case top emitting head, be arranged at the rear end mass of housing inner bottom part and by being bolted to the piezoelectric element between described emitting head and the rear end mass, described emitting head comprises that end face is the operate portions of spherical crown convex surface.
Technique scheme has following beneficial effect at least: the emitting head of transducer of the present invention comprises that end face is the operate portions of spherical crown convex surface, this emitting head does not need to do conduction by stainless-steel sheet and can directly contact with human body, the energy loss of having avoided conduction to cause, ultrasonic power obtains hundred-percent performance, and its operational frequency bandwidth broad, ultrasonic energy is concentrated, intensity is even; Electrodeless potsherd is set between each piezoelectric ceramic piece,, thereby can effectively avoids human body to contact issuable Danger Electric shock risk even generation piezoelectric ceramic piece explosion etc. are former thereby cause short circuit also can not form the loop.
Description of drawings
Fig. 1 is the sectional structure chart of the ultrasonic transducer of the embodiment of the invention.
The specific embodiment
Ultrasonic transducer of the present invention shown in Figure 1 comprises: emitting head 1, rear end mass 2, bolt 3, piezoelectric element 4 and housing 5.
Wherein, emitting head 1 comprises that end face is the operate portions 12 of spherical crown convex surface and protrudes the connecting portion 11 that stretches in the housing 5 in the middle part of the bottom surface of operate portions 12, and the connecting portion 11 of emitting head 1 is arranged on housing 5 inside, and the operate portions 12 of emitting head 1 is stretched out from housing 5 tops.Rear end mass 2 is arranged on the bottom in the housing 5, and piezoelectric element 4 is fixed between emitting head 1 and the rear end mass 2 by bolt 3, and described bolt 3 is fixed on the connecting portion 11.
Described piezoelectric element 4 comprises at least two piezoelectric ceramic pieces 41 and is arranged on electrodeless electrode slice 42 between adjacent two piezoelectric ceramic pieces 41.Wherein, electrodeless electrode slice 42 is not for there being the potsherd of electrode.The piezoelectric element 4 of present embodiment comprises 4 piezoelectric ceramic pieces 41 and is disposed on 3 electrodeless electrode slices 42 between the piezoelectric ceramic piece 41, can adopt the piezoelectric ceramic piece 41 of varying number and electrodeless electrode slice 42 is set between adjacent two piezoelectric ceramic pieces 41 according to application need when specifically implementing and can effectively avoid short circuit to form the Danger Electric shock risk that the loop causes.
The outside of described piezoelectric element 4 is surrounded by one deck fiberglass cloth 6, can further prevent to cause owing to transducer is charged the problem of getting an electric shock.
Be equipped with at least one mounting groove on connecting portion 11 and rear end mass 2, correspondence is embedded with waterproof grommet in mounting groove.Between the inwall of the connecting portion 11 of emitting head 1 and housing 5, be provided with first waterproof grommet 7 and second waterproof grommet 8 in the present embodiment; Between the inwall of rear end mass 2 and housing 5, be provided with the 3rd waterproof grommet 9.During concrete enforcement in order better to realize waterproof effect, can between the inwall of connecting portion 11 and housing 5, a plurality of waterproof grommets be set, accordingly between the inwall of rear end mass 2 and housing 5 a plurality of waterproof grommets are set, double-layer seal can effectively prevent to leak.
Between the bottom surface of the operate portions 12 of emitting head 1 and housing 5, be provided with crash roll 10, the noise that is produced in the time of can effectively reducing ultrasonic transducer work.
Described housing 5 is a Stainless Steel Shell, and emitting head 1 adopts the light aluminum alloy material to make, and rear end mass 2 is a metal derby.
Transducer of the present invention adopts emitting head to comprise that end face is the operate portions of spherical crown convex surface, and this emitting head is fit to the human body contact, and its operational frequency bandwidth broad, and ultrasonic energy is concentrated, intensity is even; Electrodeless potsherd is set between each piezoelectric ceramic piece,, thereby can effectively avoids human body to contact issuable Danger Electric shock risk even generation piezoelectric ceramic piece explosion etc. are former thereby cause short circuit also can not form the loop; This transducer does not need steel plate to do conduction can directly to contact with solution, the energy loss of having avoided conduction to cause, and ultrasonic power obtains hundred-percent performance, can not hurt the problem that people and transducer shorten service life because of pasting bad generation high temperature.
The above is the specific embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also are considered as protection scope of the present invention.
