Transmission module of dental descaler

Abstract

The invention provides a transmission module of a dental descaler. The transmission module comprises an amplitude-change pole (1) and a working tip (2), wherein the amplitude-change pole (1) and the working tip (2) are provided with flow channels which communicate with each other; a liquid outlet is formed in the working tip (2); and a liquid inlet is formed in the amplitude-change pole (1). The transmission module is characterized in that the liquid inlet is connected to a liquid inlet pipe or a liquid inlet joint (3). The transmission module has the advantages that the flow channel structureis particularly suitable for the condition that a transducer adopts a magnetostrictive rod.

Description

technical field [0001] The invention relates to the technical field of tooth scaler related structures, in particular to a transmission module of a tooth scaler. Background technique [0002] The working principle of the tooth scaler is to transmit the vibration to the working tip through the transducer, and the working tip realizes cleaning and other functions. The transmission module is one of the core parts. The transmission module is mainly composed of the horn and the working tip. In the prior art , a more preferred solution is: one end of the horn is connected to the working tip, and the other end of the horn is connected to the transducer, so that the vibration of the transducer is transmitted to the working tip. [0003] The currently used water channel setting structure is more preferably the scheme disclosed by a tooth scaler handle with the authorized publication (announcement) number CN205433973U. The water pipe 3 extends to the working tip 8 through the transduc...

Problems solved by technology

It can be seen that the magnetic oxygen composite body 3 and the connecting rod 2 have at least one water inlet at one end to be placed in the accommodating cavity 71 to supply water, that is, the magnetic oxygen composite body 3 and the connecting rod 2 have at least one water inlet. One end of a water inlet is soaked in water, and there is still a big problem, and from an engineering point of view, it is difficult to implement. For example, the outer wall of the connecting rod 2 is provided with a sealing ring to prevent water from overflowing out of the accommodating cavity. 8. When the magnetic-oxygen complex 3 drives the connecting rod 2 to vibrate, there will be a gap between the connecting rod 2 and the sealing ring 8 due to the vibration, resulting in obvious leakage. In addition, the water body will consume the energy of the magnetic-oxygen complex 3 when it vibrates, so that The vibration loss is too large, the vibration requirements cannot be met, and the performance cannot be guaranteed. At the same time, the magnetic oxygen complex 3 is soaked in water, which brings excessive vibration to the water body and affects the water spray. In addition to the public scheme of this utility patent, there are similar schemes, but the ideas they adopt are the same as above. In order to supply water, they need to be soaked in water or liquid. In short, the degree of disclosure and enlightenment of the prior art is limited. For the case where the transducer adopts a magnetostrictive rod, How to set up the runner structure is still very difficult
