Description
Technical field
The utility model relates to ultrasonic scaling cleaner handgrip PZT (piezoelectric transducer), the sealing structure of a kind of ultrasonic scaling cleaner handgrip PZT (piezoelectric transducer).
Background technology
Current domestic dentistry ultrasonic dental scaler is commonly used piezoelectric structure predominantly mobile jib and sequentially passes through piezoelectric ceramics and electrode copper sheet mesopore and be locked on ultrasonic transformer by screw thread, electrode copper sheet two ends applies voltage and realizes the electric energy high-frequency energy conversion to kinetic energy by inverse piezoelectric effect.But because piezoelectric principle is the most sensitive to resistance, when piezoelectric ceramics surface enters a small amount of moisture, the short circuit to piezoelectric ceramics can be formed under high voltages, cause the power of tooth cleaner handgrip to diminish even and lost efficacy.The inner sealing of existing market handle commonly uses glue sealing, and glue is easy aging embrittlement in long term high temperature and dither, makes isolation between handle inner water route and piezoelectric electrode lose efficacy, causes handle power little or water route is charged.
Utility model content
The purpose of this utility model is to provide the sealing structure of a kind of ultrasonic scaling cleaner handgrip PZT (piezoelectric transducer), with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of the utility model offer:
A kind of sealing structure of ultrasonic scaling cleaner handgrip PZT (piezoelectric transducer), including ultrasonic transformer, sealing ring, mobile jib, piezoelectric ceramics, electrode copper sheet, external insulation layer and inner insulating layer, described mobile jib sequentially passes through piezoelectric ceramics and the mesopore of electrode copper sheet, and mobile jib is with the form fixing connection ultrasonic transformer being screwed；It is additionally provided with sealing ring between described mobile jib and ultrasonic transformer, and sealing ring is by threadeding and compress between mobile jib with ultrasonic transformer, thus form fit sealing.
As further program of the utility model: described external insulation layer and inner insulating layer are respectively arranged on outside and the inner side of piezoelectric ceramics.
Compared with prior art, the beneficial effects of the utility model are: increase sealing ring design between the utility model ultrasonic transformer and mobile jib, the water power isolation of handle inner is strengthened from electrical safety angle, strengthen security performance, use angle to strengthen the sealing intensity in water route and electrode piece from product, extend service life reduction use cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sealing structure of the utility model a kind of ultrasonic scaling cleaner handgrip PZT (piezoelectric transducer).
In figure: 1-ultrasonic transformer, 2-sealing ring, 3-mobile jib, 4-piezoelectric ceramics, 5-electrode copper sheet, 6-external insulation layer, 7-inner insulating layer, 13-gluing position.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of sealing structure of ultrasonic scaling cleaner handgrip PZT (piezoelectric transducer), including ultrasonic transformer 1, sealing ring 2, mobile jib 3, piezoelectric ceramics 4, electrode copper sheet 5, external insulation layer 6 and inner insulating layer 7, described mobile jib 3 sequentially passes through piezoelectric ceramics 4 and the mesopore of electrode copper sheet 5, and mobile jib 3 is with the form fixing connection ultrasonic transformer 1 being screwed；It is additionally provided with sealing ring 2 between described mobile jib 3 and ultrasonic transformer 1, and sealing ring 2 is by threadeding and compress between mobile jib 3 with ultrasonic transformer 1, thus form fit sealing.
Described external insulation layer 6 and inner insulating layer 7 are respectively arranged on outside and the inner side of piezoelectric ceramics 4.
Operation principle of the present utility model is: be additionally provided with sealing ring 2 between mobile jib 3 and ultrasonic transformer 1, and sealing ring 2 is by threadeding and compress between mobile jib 3 with ultrasonic transformer 1, thus form fit sealing, the risk occurred after glue ageing failure at gluing position 13 is prevented by sealing ring 2.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize the utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in the utility model.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of specification is only for clarity sake, specification should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
