[0002] Saliva suction is a fundamental nursing skill in dental clinics. It involves using a saliva suction device to remove water droplets, debris, blood, and saliva from the oral cavity during dental treatments to maintain a clear field of vision and facilitate smooth procedures. It is widely used in clinical work, such as tooth preparation, restoration bonding, and basic periodontal treatment. However, existing saliva suction devices have limitations. Due to the limited space in the patient's mouth and the limited angle of the surgical light, they cannot fully visualize the internal structure of the alveolar bone. During dental restorations, the dentist's field of vision is easily obstructed by the high-speed turbine and the water droplets it generates, making it difficult to accurately remove accumulated blood, debris, and saliva from the alveolar bone. Furthermore, the mouth mirror inserted into the mouth is easily contaminated by splashing blood, debris, and saliva, rendering it ineffective and further increasing the difficulty and time of treatment. Therefore, improvements are needed. Summary of the Invention

[0032] Example 2

[0033] Working principle:

[0034] S1. Before use, the present invention checks the cleaning device 232 to ensure it is clean and whether it has been replaced. The cleaning device 232 is kept clean before each use. The negative pressure device is connected to the tail interface 12 at the tail of the saliva suction body 1.

[0035] S2. When in use, the user holds the handheld part 13 and presses the light control component 131. The light strip 223 lights up, and the slider 24 is pushed forward. The slider 24 drives the first connecting rod 21 to move forward in parallel. As the first connecting rod 21 slides horizontally, the annular connecting rod 221 on the first connecting rod 21 drives the second connecting rod 224 and simultaneously drives the push block 231 to move forward. The cleaning device 232 moves forward, and the degreasing cotton 2332 at the bottom of the cleaning device 232 wipes the surface of the lens 233 and presses the lens 233 into the groove 234. The fixing block 235 compresses the spring 236 to contract.

[0036] S3. At this time, the ring connecting rod 221 drives the sleeve 222 to move forward, and the sleeve 222 drives the lamp strip 223 to rotate around the other end of the lamp strip 223, adjusting the illumination angle of the lamp strip 223 so that the light shines horizontally, making it convenient for the user to observe the inside of the patient's oral cavity.

[0037] S4. When the user inserts this utility model into the patient's oral cavity, push the slider 24 to adjust the angle of the light strip 223, causing the light strip 223 to tilt. As the light strip 223 tilts, the push block 231 drives the cleaning device 232 to slide backward. Without pressure, the spring 236 in the second groove 237 rebounds, causing the lens 233 to rotate around the hinge. The lens 233 protrudes at a certain angle to facilitate the user's observation of the oral cavity. If the lens 233 is contaminated by blood, saliva, or other substances from the dental drill, the slider 24 can be slid, and the push block 231 drives the cleaning device 232 to clean the surface of the lens 233.

[0038] S5. After use, clean the exterior of the utility model and replace the cleaning device 232.

[0039] Example 3

[0040] The light strip 223 of this invention does not illuminate the lens 233, thus avoiding light reflection from affecting the user's vision.
