Ultrasonic Tooth Cleaner Back Suction Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During ultrasonic tooth cleaning, the aerosol generated by the collision of cooling water with the working tip is not effectively absorbed, leading to inhalable contaminants and inefficiencies in existing absorption methods.
Innovation Solution
An ultrasonic back suction-integrated tooth cleaner is designed with a pipeline structure that includes a water supply pipeline and a back suction pipeline, where a negative pressure is maintained to absorb the aerosol effectively, using an electromagnetic valve and electric valve to control the water supply and back suction functions, and a silicone aggregation and suction sleeve to enhance aerosol collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a saliva ejector or semi-fixed cover is used for aerosol absorption, then the absorption function is provided, but the absorption efficiency is insufficient because the working tip moves and cannot be completely followed
Solution Approach 1:
The patent combines the ultrasonic cleaning function and back suction function into a single integrated handle. The back suction pipeline is directly integrated into the handle structure, allowing the suction opening to move together with the ultrasonic working tip during tooth cleaning operations, thereby maintaining continuous and efficient aerosol absorption without the need for separate tracking mechanisms.
2Productivity
If a back suction pipeline is designed in the limited space of the tooth cleaner handle, then the aerosol can be absorbed effectively, but the operating habits and size requirements of existing dental appliances may be compromised
Solution Approach 1:
The back suction pipeline is nested within the existing handle structure. The pipeline is arranged concentrically or in a space-efficient configuration inside the handle, allowing the suction function to be incorporated without significantly increasing the overall handle dimensions, thus maintaining compatibility with existing dental appliance size standards.
Solution Approach 2:
The back suction pipeline utilizes the radial or axial space within the handle rather than extending the handle length. By arranging the pipeline in a compact three-dimensional configuration within the existing handle volume, the design maintains standard handle dimensions while incorporating the additional suction function.
3Productivity
If multiple pipelines (water supply and back suction) are integrated into the handle, then the aerosol absorption function is achieved, but the device complexity increases
Solution Approach 1:
The water supply pipeline and back suction pipeline are merged into a single integrated handle structure with a unified control system. Both pipelines share common components such as the electromagnetic valve, electric valve, and control circuitry, reducing the overall system complexity compared to having separate independent systems.
Solution Approach 2:
The handle is designed as a multi-functional unit that performs both ultrasonic cleaning and back suction operations. The electromagnetic valve and electric valve control both water supply and back suction functions, allowing a single component to serve multiple purposes and reducing the total number of separate control mechanisms required.

AI summary
An ultrasonic back suction-integrated tooth cleaner includes a tooth cleaner host and a tooth cleaner handle. The tooth cleaner host includes a pipeline structure inside. Head ends of a water supply pipeline and a back suction pipeline both extend out of a housing of the tooth cleaner host and are connected to a tail end of the tooth cleaner handle. In the present invention, a back suction pipeline is added to an existing tooth cleaner host, so that the host is adapted to an integral tooth cleaner handle with a back suction function. A flow rate in the water supply pipeline is regulated by using an electromagnetic valve, so that a requirement for accurately controlling a water output volume is satisfied. The tooth cleaner handle is ingeniously designed with a back suction pipeline inside the existing ultrasonic handle, so that an aerosol is effectively controlled during ultrasonic tooth cleaning.
