Example one

As shown in fig. 1 to 2, the ultrasonic dental scaler without damaging teeth of the present embodiment comprises a handle housing 2 and a transducer 3 disposed in the handle housing 2, wherein a first end 101 of a horn is fixedly connected to a front end of the transducer 3, and a second end 102 of the horn extends out of the handle housing 2; the second end 102 of the horn is attached to a tip 6 for cleaning teeth.

In this embodiment, the ultrasonic scaler performs a tooth washing operation using an ultrasonic tooth cleaning technique. As shown in figure 1, the tooth cleaning handle of the utility model also comprises an electric wire 4 and a water pipe 5, and the high-frequency and high-energy vibration generated by the ultrasonic waves can break up dental calculus and tooth stain on the surface of the tooth through the smooth working tip. As in the prior art, the working tip 6 of the present embodiment is provided with a water outlet to generate water mist to wash away the broken stones and plaque and cool the working tip. As shown in fig. 1, in the ultrasonic dental scaler, a transducer 3 is used to generate ultrasonic waves for a dental cleaning device and transmit the vibrations to a tip 6 through an amplitude transformer 1.

The horn is an important component of an ultrasonic vibration system, and has a main function in the vibration system to amplify the particle displacement or velocity of mechanical vibration and concentrate ultrasonic energy on a smaller area, i.e. energy concentration, so that the horn is also called an ultrasonic shift lever or an ultrasonic energy concentrator. The amplitude transformer is a functional component which is matched with an ultrasonic transducer to change the ultrasonic vibration amplitude as the name suggests. The main functions of the transducer are to change the amplitude (generally increase) of the transducer, improve the vibration velocity ratio, improve the efficiency, improve the mechanical quality factor, strengthen the heat resistance, expand the adaptive temperature range and prolong the service life of the transducer. The ultrasonic transducer adjusts the load matching between the transducer and the ultrasonic tool head by installing the amplitude transformer, reduces the resonance impedance, improves the electroacoustic conversion efficiency by enabling the ultrasonic transducer to work at the resonance frequency, effectively reduces the heat productivity of the ultrasonic transducer, and prolongs the service life.

In the present embodiment, the horn 1 has two attached ends-a first end 101 of the horn and a second end 102 of the horn, as shown in fig. 1 and 2. The front end of the transducer 3 is fixedly connected to a first end 101 of the horn, while a second end 102 of the horn extends outside the handle housing 2. The second end 102 of the horn is curved to one side and is fixedly attached to the tip 6. The curvature of the second end 102 of the horn is such that the working tip 6 will clean the teeth. As shown in fig. 1 and 2, in this embodiment, the tip 602 of the tip is a conical cylinder, the tip of which cleans the teeth of the user. In other embodiments, the tip of the tip may have other shapes such as a spade shape, a tab shape, etc.

The utility model discloses a become width of cloth pole direct and the mode of the outside fixed connection of work point at handle shell 2, avoided present clean tooth handle width of cloth pole to be located clean tooth handle shell, not only need professional instrument when changing the clean tooth device of being connected with the width of cloth pole, still need open the drawback of shell. The replacement of the work tip is more convenient.

In order to achieve a fixed connection of the horn 1 and the tip 6. The second end 102 of the horn is provided with a mounting hole 13, the working tip 6 comprises a connecting end 601 and a tip 602, the connecting end 601 is inserted into the mounting hole 13, and is locked and fixed by a locking device and limited by a limiting device.

As shown in fig. 2, the locking device in this embodiment uses a lock nut 11, and the front end of the internally threaded hole of the lock nut 11 is a tapered hole that gradually decreases toward the tip 6. The front end of the second end 102 of the amplitude transformer is hollow, a mounting hole 13 is formed, and the inner surface of the amplitude transformer is provided with threads matched with the locking nut 11. The spacing device uses a locating ring 12 and a locating groove 14.

In this embodiment, in order to achieve the locking effect, the outer diameter of the connecting end 601 cannot be smaller than the inner diameter of the mounting hole 13. The positioning ring 12 of the limiting device is arranged on the outer surface of the connecting end 601 of the operating tip and is an annular bulge integrally formed with the operating tip; the locating slot 14 is located on the inner wall of the mounting hole 13 at the second end 102 of the horn and is an annular groove that mates with the locating ring 12.

In this embodiment, the outer diameter of the positioning ring 12 is larger than the inner diameter of the mounting hole 13 when locked by the locking nut 11, so that the connection end 601 and/or the mounting hole 13 must be deformed during the process of pushing the positioning ring 12 into the positioning groove 14. This assembly limiting effect is achieved in this embodiment by deformation of the mounting hole 13 caused by deformation of the horn second end 102. The limiting combination can mainly limit the movement of the working tip 6 in the axial direction.

As shown in fig. 2, the positioning ring 12 of the tip protrudes from the outer surface of the connecting end 601, so that the positioning ring can smoothly enter the positioning groove 14, the front end of the second end 102 of the horn is further provided with at least 2 slits along the radial direction, and the slits extend from the opening of the mounting hole 13 to the bottom of the mounting hole 13. When the connecting end 601 of the operating tip is inserted into the mounting hole 13, the second end 102 of the slotted horn deforms, so that the connecting end 601 is integrally inserted into the mounting hole 13, and after the ring 12 to be positioned reaches the positioning groove 14, further locking operation can be performed.

The lock nut 4 is tightened by a wrench tool. When the working tip 6 is locked, the internal thread of the locking nut 11 is meshed with the locking thread 15 on the outer surface of the second end of the amplitude transformer to rotate into the mounting opening 13 of the second end 602 of the amplitude transformer, the front end of the second end 602 of the amplitude transformer is screwed into the conical part of the locking nut 11 along with the rotation, the slit on the front end of the second end 602 of the amplitude transformer is closed, meanwhile, the positioning ring 12 is tightly matched with the positioning groove 14 to realize the limiting, and the working tip connecting end 601 inserted into the second end 602 of the amplitude transformer is locked and fixed in the mounting hole 13.

In the embodiment, the working tip 6 is firmly locked in the second end 102 of the amplitude transformer through the locking device, and the axial limit of the working tip 6 is further realized through the matching of the positioning ring 12 and the positioning groove 14, so that the working tip 6 is more firmly fixed.

As shown in fig. 5 and fig. 6, the tip of this embodiment at least includes a first working body 603 and a second working body 604, and the first working body 603 and the second working body 604 are integrally formed or fixedly connected to form a working tip 6 with different hardness regions. The first working body 603 and the second working body 604 may be made of materials having different hardness. As shown in fig. 6, the first working body 603 and the second working body 604 form a tip having regions of different hardness in cross section. Meanwhile, the first working body 603 is positioned at one side close to the cleaned teeth, and the hardness of the first working body is greater than that of the second working body 604; or the toughness of the second working body 604 is greater than the toughness of the first working body 603. The top surface of the first working body 603 is completely covered by the bottom surface of the second working body 604.

In this embodiment, the first working body 603 and the second working body 604 may be made of materials with different hardness and/or toughness. Due to the design, when the first working body 603 which is high in hardness and poor in toughness and is used for cleaning teeth is broken, the second working body 604 still cannot be broken, and the first working body 604 and the second working body are integrally formed or fixedly connected into a whole, so that the first working body 604 cannot be separated from the body of the working tip 6, namely the situation that the working tip 6 is completely broken cannot occur. For example, the first working body 603 is made of a material similar to bamboo fiber, while the second working body 604 is made of bamboo skin fiber with better toughness but lower hardness, when the first working body 603 is broken in the using process, because the second working body 604 is not broken, the first working body 603 is still attached to the surface of the second working body 604, and the situation that the first working body 603 falls into the oral cavity of the user due to the breakage does not occur. Therefore, the broken working tip falls into the oral cavity in the process of tooth washing, and the danger coefficient caused by the broken working tip is greatly reduced.

The tip material that this embodiment used can include other non-metallic material such as carbon fiber or plastics, and non-metallic material not only makes the part of contact tooth rich in elasticity in the tip of the metal material of using at present, but also has reduced the fear of people to the work tip of washing teeth and has felt, more is favorable to the tooth cleaning machine to enter into ordinary family, consequently the utility model provides a non-metallic material is preferentially adopted to the work part of tip. Of course, metal materials of different hardness and toughness may be used.

As shown in fig. 1, the ultrasonic dental scaler in this embodiment further includes an image capturing device, which is a camera including a lens 8 and a lens cover 9 wrapped around the lens 8. In order to improve the brightness of image acquisition of the camera, an illuminating lamp 10 is also arranged in the lens sleeve 9. The middle part of the back surface of the lens sleeve 9 is fixed with the tooth cleaning handle shell 2 of the ultrasonic tooth cleaning machine through a shape-deformable shaping hose 7.

Typical shaped hoses 7 include metal shaped hoses. The metal shaping hose is a composite metal pipe formed by winding and coating a metal spring steel wire and a galvanized iron wire or other metal wire materials, the hollow part is externally provided with spiral grains, electric wires with certain sizes can pass through the inside of the pipe hole, the hose can be bent into a certain shape in a three-dimensional space at will and can keep the shape of the hose, the length and the size are basically stable during bending, the bent hose has certain supporting force to support objects with certain weight, and the supporting force is controllable within a certain range.

When an operator holds the tooth cleaner to clean teeth, the lens sleeve 9 enters the cavity along with the work tip 6, the lens 8 faces the tip 602 of the work tip by adjusting the angle of the shaping hose, and the illuminating lamp 10 is turned on to enable objects around the tip 602 of the work tip to enter the visual field of the lens 8. The lens 8 outputs the image to the display device by wired communication or wireless communication. The operator can see the soft tartar and the position of tartar through the display device when washing the teeth, the cleaning process is more pertinent, and can see well whether the teeth of the operator are sufficiently cleaned.

After the sizing hose is connected with the camera, the image acquisition device can be adjusted and kept at different angles in the process of tooth washing according to the tooth washing requirement of a user. The display device connected with the camera in a communication way enables the tooth washing part of the whole tooth washing process to be carried out under the monitoring of the user. Not only greatly relieves the fear of tooth washing of a user, but also greatly improves the safety of the tooth washing process. The display device can be a display screen or an intelligent terminal with a display function, such as a mobile phone, a tablet computer and the like.
