Technical Field

[0001] This utility model relates to the field of oral surgery technology, specifically to a mouth mirror with saliva suction function. Background Technology

[0002] A mouth mirror is a commonly used examination tool in oral medicine. During clinical diagnosis and treatment in dentistry, a mouth mirror is often used to expose and observe the patient's oral cavity, allowing observation of areas that are difficult to see directly, such as the distal, lingual, and palatal surfaces of teeth. By adjusting the angle and position of the mouth mirror, different angles of view can be obtained, enabling a comprehensive examination of lesions in the oral cavity. However, when cooling or rinsing is involved, a saliva suction tube is often needed to remove saliva, increasing the complexity of the procedure and causing inconvenience for the dentist. If the mouth mirror could simultaneously retract the soft tissues of the mouth, expose the operating field, and suction saliva, it would be beneficial for the dentist's operation and observation, improving the efficiency of the dentist's work.

[0003] The utility model patent with publication number CN220832981U provides a three-in-one gun-type saliva suction mouthpiece. The mouthpiece is designed to have the water suction function of a saliva suction tube. During operation, it can only suck away the mist and water droplets on the mouthpiece, but it is not effective at suctioning saliva or other liquids in the oral cavity. Utility Model Content

[0004] The purpose of this invention is to provide a mouth mirror with a saliva suction function to solve the problem mentioned in the background art that it can only remove mist and water droplets on the mouth mirror during operation, but has poor suction effect on saliva or other liquids in the oral cavity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mouth mirror with a saliva suction function, comprising a handle, a mouth mirror stem fixedly connected to the upper surface of one end of the handle, a mouth mirror body fixed to the upper end of the mouth mirror stem, a reflective plane mirror mounted on the surface of the mouth mirror body, a first fixing tube fixed to the side surface of the handle, a telescopic tube provided on the upper surface of the first fixing tube, a positioning support block slidably connected to the outer surface of the mouth mirror stem, a second fixing tube fixed to the upper surface of one end of the positioning support block, a saliva suction head mounted on the upper surface of the second fixing tube, and an adjustment mechanism provided inside the handle, which performs friction braking on the support column by pressing the slider and the friction locking block.

[0006] Preferably, the first fixed tube is connected to the telescopic tube, and the surface of the positioning support block is provided with an opening, and the opening of the positioning support block is connected to the second fixed tube and the telescopic tube respectively.

[0007] By adopting the above technical solution, the first fixed tube is connected to the telescopic tube, and the second fixed tube and the telescopic tube are connected respectively through the opening of the positioning support block, so as to facilitate water suction through the saliva suction head.

[0008] Preferably, the adjustment mechanism includes a support column fixedly connected to the lower surface of the positioning support block. The lower end side surface of the support column has an opening, and a pressing slider is slidably connected to the inner wall of the opening. A friction block is fixed to one end of the pressing slider, and a first magnet is embedded in the surface of the pressing slider. The support column has a cavity inside, and a piston column is slidably connected to the inner wall of the cavity. A second magnet is fixed to the lower surface of the piston column, and an anti-slip airbag is fixed to the inner wall of the groove of the positioning support block.

[0009] By adopting the above technical solution, the support column of the adjustment mechanism can be used to drive the positioning support block to slide, and the positioning support block can drive the telescopic tube to extend and retract.

[0010] Preferably, the lower end of the support column extends through the upper surface of the handle, and the support column and the handle are slidably connected. The side surface of the pressing slider is provided with an anti-slip strip.

[0011] By adopting the above technical solution, the user can easily move the support column by pressing the anti-slip strip of the slider.

[0012] Preferably, a spring is connected between the pressing slider and the supporting column, and a rubber brake block is provided on the surface of the friction block facing the pressing slider.

[0013] Using the above technical solution, pressing the slider causes the friction block to slide, which facilitates the friction block to be fixed against the inner wall of the handle.

[0014] Preferably, the lower end of the cavity of the support column is connected to the opening of the support column, and the magnetic poles of the opposite ends of the first magnet and the second magnet are opposite.

[0015] Using the above technical solution, pressing the slider causes the first magnet to correspond to the second magnet.

[0016] Preferably, a spring is connected between the piston rod and the support column, and the piston rod is connected to the cavity of the anti-slip airbag, which is a ring-shaped design.

[0017] Using the above technical solution, the piston rod is driven to move by the second magnet, so that the piston rod draws air from the anti-slip airbag.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the mouth mirror with saliva suction function:

[0019] 1. The device is equipped with a telescopic tube and a positioning support block. When the device is working, the positioning support block drives the second fixed tube to move, which facilitates the second fixed tube to absorb excess water through the suction head. The telescopic tube also facilitates the transfer of water to the first fixed tube, thereby increasing the water absorption range and improving the practicality of the device.

[0020] 2. The device is equipped with a pressing slider and a friction block. When the device is working, the pressing slider is pushed by the spring on the surface of the support column, which causes the pressing slider to drive the friction block to move. The friction block abuts against the inner wall of the handle, thereby fixing the support column and facilitating the support column to limit the positioning support block, thus improving the stability of the positioning support block and the second fixing tube.

[0021] 3. Equipped with a second magnet and an anti-slip airbag, when the device is in operation, pushing the pressing slider unlocks the friction block, facilitating the lifting and lowering of the support column. Simultaneously, the first magnet attracts the second magnet, causing the piston to draw air from the anti-slip airbag. When the pressing slider is pushed by the spring, thereby fixing the friction block, the piston is pulled upward by the surface spring, pushing air towards the anti-slip airbag. This causes the anti-slip airbag to expand and adhere to the surface of the lens handle for anti-slip, further improving stability. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a mouth mirror with saliva suction function, including a handle 1, a mouth mirror handle 2, a mouth mirror body 3, a reflective plane mirror 4, a first fixing tube 5, a telescopic tube 6, a positioning support block 7, a second fixing tube 8, a saliva suction head 9, a support column 10, a pressing slider 11, a friction block 12, a first magnet 13, a piston column 14, a second magnet 15, and an anti-slip airbag 16. The handle 1 has a mouth mirror handle 2 fixedly connected to the upper surface of one end. The mouth mirror body 3 is fixed to the upper end of the mouth mirror handle 2. The surface of the mouth mirror body 3 is equipped with a reflective plane mirror 4. The first fixing tube 5 is connected to the telescopic tube 6. The surface of the positioning support block 7 is provided with an opening, and the opening of the positioning support block 7 is connected to the second fixing tube 8 and the telescopic tube 6 respectively. When using this device, the first fixing tube 5 is first connected to a negative pressure device, and then the telescopic tube 6 and the second fixing tube 8 are connected through the positioning support block 7 respectively, so as to facilitate the suction of water through the saliva suction head 9.

[0031] A first fixing tube 5 is fixed to the side surface of the handle 1. A telescopic tube 6 is provided on the upper surface of the first fixing tube 5. The adjustment mechanism includes a support column 10, which is fixedly connected to the lower surface of the positioning support block 7. An opening is provided on the lower side surface of the support column 10, and a pressing slider 11 is slidably connected to the inner wall of the opening of the support column 10. A friction block 12 is fixed to one end of the pressing slider 11. A first magnet 13 is embedded in the surface of the pressing slider 11. A cavity is provided inside the support column 10, and a piston column 14 is slidably connected to the inner wall of the cavity of the support column 10. A second magnet 15 is fixed to the lower surface of the piston column 14. An anti-slip airbag 16 is fixed to the inner wall of the groove of the positioning support block 7. When working, by pushing the pressing slider 11, the pressing slider 11 drives the friction block 12 to unlock, which makes it easier to push the pressing slider 11 to drive the support column 10 to rise and fall. The support column 10 then drives the positioning support block 7 and the second fixing tube 8 to move, which is beneficial to changing the water absorption position of the device.

[0032] A positioning support block 7 is slidably connected to the outer surface of the mouth mirror handle 2. A second fixing tube 8 is fixed to the upper surface of one end of the positioning support block 7. The lower end of the support column 10 passes through the upper surface of the handle 1, and the support column 10 and the handle 1 are slidably connected. An anti-slip strip is provided on the side surface of the pressing slider 11. A spring is connected between the pressing slider 11 and the support column 10. A rubber brake block is provided on the surface of the friction block 12 facing the pressing slider 11. When the pressing slider 11 is pushed, the pressing slider 11 drives the first magnet 13 on the surface to correspond to and attract the second magnet 15, so that the second magnet 15 drives the piston column 14 to draw air from the anti-slip airbag 16, so that the anti-slip airbag 16 does not interfere with the movement of the positioning support block 7.

[0033] The upper surface of the second fixed tube 8 is equipped with a saliva suction head 9. The inside of the handle 1 is equipped with an adjustment mechanism, which uses a pressing slider 11 and a friction block 12 to frictionally brake the support column 10. The lower end of the cavity of the support column 10 is connected to the opening of the support column 10. The magnetic poles of the opposite ends of the first magnet 13 and the second magnet 15 are opposite. A spring is connected between the piston column 14 and the support column 10, and the piston column 14 is connected to the cavity of the anti-slip airbag 16. The anti-slip airbag 16 is a ring design. When the spring on the surface of the support column 10 pushes the pressing slider 11 to slide back to its original position, the pressing slider 11 causes the first magnet 13 and the second magnet 15 to be misaligned, which makes it easier for the spring on the inner wall of the cavity of the support column 10 to pull the piston column 14 to slide upward, so that the piston column 14 pushes air into the anti-slip airbag 16. After the anti-slip airbag 16 expands, it fits the surface of the mouthpiece handle 2, thereby further improving stability.

[0034] Working principle: When using this mouth mirror with saliva suction function, pushing the pressing slider 11 causes the friction block 12 to release the support column 10, which facilitates the movement of the support column 10 by pressing the slider 11. The support column 10 then causes the positioning support block 7 and the second fixing tube 8 to slide, thereby changing the water suction position. When the pressing slider 11 is released, the friction block 12 abuts against the inner wall of the handle 1. At the same time, the pressing slider 11 causes the first magnet 13 and the second magnet 15 to be misaligned, causing the spring on the inner wall of the support column 10 to pull the piston column 14 upward, which inflates the anti-slip airbag 16, further improving stability and increasing overall practicality.
