Problems solved by technology

However, the current ultrasonic toothbrushes mainly appear in developed countries. They are expensive, and the ultrasonic frequency generated is high and the power density is low. It is difficult to reach the critical point of the cavitation effect, and it is difficult to achieve the effect of ultrasonic cleaning teeth.

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1 to Figure 9 As shown, a novel ultrasonic dental cleaning device of the present invention includes a tool head 1 and an ultrasonic transducer 2 fixedly connected to the tool head 1, the ultrasonic transducer 2 includes a middle plate 3, and the middle plate 3 is set There is at least one piezoelectric ceramic sheet 4, the tool head 1 is connected with a detachable toothbrush head 5 or tooth cleaning head 6, and the vibration frequency range of the ultrasonic transducer 2 is between 10 kHz and 100 kHz .

[0028] The ultrasonic transducer 2 is mainly composed of an intermediate plate 3 and a piezoelectric ceramic sheet 4. When the number of piezoelectric ceramic sheets 4 is two, they are respectively bonded to the upper and lower surfaces of the intermediate plate 3, and the intermediate plate 3 is bonded to the The piezoelectric ceramic sheet...

Abstract

The invention relates to the technical field of oral cleaning devices, and in particular to a novel ultrasonic tooth cleaning device. The device comprises a tool head and an ultrasonic transducer fixedly connected with the tool head; the ultrasonic transducer comprises an intermediate plate; the intermediate plate is provided with at least one piezoelectric ceramic sheet; and the tool head is connected with a detachable toothbrush head or a tooth cleaning head, wherein the vibration frequency range of the ultrasonic transducer is between 10 kilohertz and 100 kilohertz. According to the invention, installation and use of the toothbrush head and the tooth cleaning head can be both considered, and the mature piezoelectric ceramic bimorph structure is used as the ultrasonic transducer, so thatvibration frequency is kept between 10 kilohertz and 100 kilohertz, a good tooth cleaning effect is ensured, and production cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of oral cavity cleaning devices, in particular to a novel ultrasonic tooth cleaning device. Background technique [0002] The history of using a toothbrush to clean teeth has a long history. It mainly removes the dirt and germs on the tooth surface through the friction between the bristles and the tooth surface. It has no effect on the places that the bristles cannot reach, such as the dirt and germs between the teeth. For a long time, common toothbrushes and electric toothbrushes have been popular in the market. The cleaning principles of common toothbrushes and electric toothbrushes are the same. They clean teeth by rubbing bristles and tooth surfaces. Brush up and down on the ground, that is, vertical brushing, while the vibration frequency and force of electric toothbrushes are relatively fixed. When rotating, it is similar to horizontal brushing on the surface of the teeth, which may cause certain wear ...
