Description

Technical Field

[0001] This utility model relates to the field of dental cleaning device technology, specifically a visual dental rinsing handle and dental cleaning device with positive pressure anti-splash function. Background Technology

[0002] Dental air polishing is an air polishing technology that uses compressed gas (usually air) to lift abrasive powder, which is then sprayed onto the tooth surface through a nozzle on a handle. The powder mixes with a liquid medium (usually water) sprayed along with the abrasive powder, effectively cleaning the tooth surface. Specifically, it can remove plaque, soft deposits, tobacco stains, and tea stains, effectively preventing periodontal disease and maintaining dental health. However, current air polishing equipment typically uses a mirror or electronic endoscope to observe the treated area in real time. During the procedure, splashing water and condensation in the mouth can interfere with the endoscopic lens's field of view, affecting the operation. Utility Model Content

[0003] In order to overcome the defects in the existing technology, the purpose of this utility model is to provide a visual dental rinsing handle and teeth cleaning device with positive pressure anti-splash function.

[0022] Example 1:

[0023] like Figure 1-3 As shown, this embodiment provides a visual dental irrigation handle with positive pressure anti-splash function, including a handle housing 1, a nozzle 2 disposed at the front end of the handle housing 1, and a nozzle 3 disposed at the front end of the nozzle 2. The nozzle 2 is also provided with a visualization mechanism 4, which includes a protective cover 41 disposed on the nozzle 2 with its front opening facing the nozzle 3, a camera 42 and a light assembly disposed inside the protective cover 41, an air jet hole 44 disposed on the side wall of the protective cover 41, and a first air pipe 45 communicating with the air jet hole 44. The first air pipe 45 is used to connect to a built-in or external positive pressure air source. Preferably, the nozzle 3 includes a first nozzle 31 for spraying liquid and a second nozzle 32 for sandblasting or air jetting. The handle housing 1 is also provided with a water pipe 5 and a second air pipe 6. The surface of the handle housing 1 is provided with a first control button 81 for controlling the working state of the first nozzle 31 and the second nozzle 32, and a second control button 82 for controlling the airflow emitted from the air jet hole 44.

[0024] The visual dental rinsing handle with positive pressure anti-splash function provided in this embodiment is generally used in conjunction with the main unit of the dental cleaning device, such as in Embodiment 2. The main unit is equipped with a liquid system, a sandblasting system, and an air system. One end of the water pipe 5 is connected to the first nozzle 31, and the other end is connected to the liquid system. One end of the second air pipe 6 is connected to the second nozzle 32, and the other end is connected to the sandblasting system and the air system through a three-way valve. In use, the user holds the dental rinsing handle and inserts it into the mouth, aligning the tip of the nozzle 2 with the teeth to be cleaned. Then, the user operates the first control button 81 with their finger to control the operation of the liquid system and the sandblasting system, thereby enabling the first nozzle 31 and the second nozzle 32 to spray water. High-speed water jets and abrasive powder clean the tooth surface. During the cleaning process, a visualization mechanism 4 on the nozzle 2 allows the camera 42, along with a light assembly, to capture real-time images of the area being cleaned. These images are then displayed to the user on the main unit's monitor or other external displays for easy real-time observation. The user can also operate the second control button 82 to activate the positive pressure air source. This positive pressure airflow from the jet nozzle 44 disperses splashing water mist and air vapor in the mouth, preventing the camera 42 from being affected by the mist. This facilitates easy real-time observation of the oral cavity during abrasive cleaning. Furthermore, the positive pressure airflow also helps dissipate heat from the camera 42 and the light assembly. After cleaning, the user can operate the control button to activate the air system, using compressed air to self-clean the second air tube 6 and the nozzle 2.

[0025] In a preferred embodiment, the positive pressure air source is an air pump 7 built into the handle housing 1. In other embodiments, the air circuit system in the main unit of the dental cleaning device can also be used directly as the positive pressure air source for the jet port 44.

[0026] As a preferred embodiment, the lamp assembly includes a plurality of LED beads 43 distributed circumferentially around the camera 42. The air jet 44 is located in front of the camera 42 and the LED beads. This design facilitates the LED beads 43 to provide illumination for the camera 42, facilitates the positive pressure airflow from the air jet 44 to dispel splashing water mist and mouth mist, and facilitates self-cleaning of the camera 42. It also facilitates the positive pressure airflow to dissipate heat from the camera 42 and the lamp assembly.

[0027] Example 2:

[0028] This embodiment provides a dental cleaning device, including a main unit and the aforementioned visual dental rinsing handle with positive pressure anti-splash function.

[0029] As a preferred embodiment, the host is equipped with a display for use with the camera 42, so that the operator can observe the operation site in the oral cavity in real time through the display.

[0030] As a preferred embodiment, the main unit is provided with a liquid system, a sandblasting system, and an air system for connecting the nozzle 3 to realize liquid spraying, sandblasting, and air spraying. The first air pipe 45 is also connected to the air system and uses the air system as the positive pressure air source. This solution uses the air system in the main unit as the positive pressure air source for the air jet hole 44, eliminating the need to install an air pump 7 in the handle or connect other external positive pressure air sources. The structure is simple and the design is ingenious.

[0031] The accompanying drawings for this embodiment are omitted.
