The present invention relates to a tooth cleaning device, and more particularly to a tooth cleaning device that can be finely adjusted.
With the improvement of living standards, people pay more and more attention to oral hygiene. Cleaning teeth has become a common health care for people to maintain oral hygiene. A tooth cleaning device is a special apparatus for cleaning teeth, which is used to remove tartar, stains, plaque, etc.
A conventional tooth cleaning device with camera function generally includes a main body, a camera and a cleaning head. The orientation of the conventional cleaning head is generally immovable. It is difficult to adjust its orientation, which will affect the normal use of the driving head.
Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
In view of the defects of the prior art, the primary object of the present invention is to provide a tooth cleaning device that can be finely adjusted. It is more convenient to use. The orientation of a cleaning head can be finely adjusted for the working position of the cleaning head, so as to ensure the normal use of the cleaning head. Furthermore, during the rotation of the cleaning head, it is possible to prevent the camera unit from being damaged, so that the camera unit is well protected.
In order to achieve the above object, the present invention adopts the following technical solutions:
A tooth cleaning device comprises a main body, a cleaning head extending out of the main body, and a camera unit. An upper end of the main body is provided with an inclined portion that is inclined downward and rearward. The camera unit is mounted to the inclined portion. An ultrasonic transducer is mounted to the inclined portion. The cleaning head is connected to the ultrasonic transducer. The ultrasonic transducer is rotatably connected to the main body. The camera unit is connected to the inclined portion and adjustable to avoid the cleaning head when rotating.
Preferably, the ultrasonic transducer is provided with a rotation limiting portion for limiting a rotation angle of the ultrasonic transducer.
Preferably, the rotation limiting portion protrudes from an upper end face of the ultrasonic transducer, a locking protrusion is provided on the inclined portion, and the rotation limiting portion abuts against the locking protrusion.
Preferably, the ultrasonic transducer includes a mounting seat, a cylindrical portion mounted to the mounting seat, and a driving portion integrally connected to a top end of the cylindrical portion. The driving portion is detachably connected to the cleaning head. The rotation limiting portion is disposed on the mounting seat and/or the cylindrical portion.
Preferably, a function button is provided on the main body.
Preferably, a display screen is provided on the main body.
Preferably, the camera unit is rotatably connected to the main body to be turned back and forth.
Preferably, a front end face of the camera unit is formed with a first finger recess corresponding to the curvature of a user's finger surface.
Preferably, a front end face of the inclined portion is formed with a second finger recess corresponding to the curvature of a user's finger surface.
Preferably, a power source for power supply is provided in the main body, a charging port is provided on a lower end face of the main body, and the charging port is electrically connected to the power source.
Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it is more convenient to use through the inclined portion. In particular, through the design of the ultrasonic transducer that is rotatable relative to the main body, the orientation of the cleaning head can be finely adjusted for the working position of the cleaning head, so as to ensure the normal use of the cleaning head. Furthermore, through the adjustable camera unit, during the rotation of the cleaning head, it is possible to prevent the camera unit from being damaged, so that the camera unit is well protected.
Secondly, the rotation limiting portion is configured to limit the rotation angle of the ultrasonic transducer, so as prevent the internal wires from breaking due to the excessive rotation of the ultrasonic transducer and to prolong the service life of the product.
Furthermore, through the cooperation of the first finger recess and the second finger recess, it is possible to avoid slippage and shifting when the camera unit is used and turned, thereby improving the anti-slip effect.
In addition, the design of the overall structure is ingenious and reasonable, the parts are easy to use, and the stability is good. It is beneficial to ensure the stability and reliability of the product performance.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
