Abstract
Description
Technical Field
[0001] This utility model relates to the field of instrument cleaning technology, specifically to a dental instrument cleaning device. Background Technology
[0002] Oral instrument cleaning is a standardized process involving pretreatment, enzyme washing, rinsing, disinfection, drying, and sterilization. It aims to thoroughly remove blood, saliva, tissue residue, and microorganisms from the surface and crevices of the instruments. First, large particles of dirt are removed by rinsing with running water or ultrasonic cleaning. Then, organic matter is broken down using an enzyme-containing cleaning agent. Finally, sterilization is carried out by high temperature and high pressure or low temperature plasma sterilization to ensure a sterile state. The entire process must follow medical device handling standards to avoid cross-infection and ensure the performance of the instruments and the safety of patients.
[0003] For example, utility model patent CN222020233U discloses a dental instrument cleaning device, including a cleaning device body; a water tank is fixedly connected to the top of the cleaning device body; a water pipe is connected to the top of the water tank; the end of the water pipe extends into the interior of the cleaning device body; multiple water outlets are opened in the middle of the water pipe; the multiple water outlets are equidistantly distributed along the length of the water pipe; the water outlets face the inner bottom of the cleaning device body; with the above structure, instruments can be rinsed and disinfected with alcohol after use. At the same time, by rotating the mesh tank, the instruments can be rotated, allowing the instruments to be rinsed and sprayed with alcohol from multiple directions, thereby reducing impurities adsorbed on the surface of the instruments, and ultimately reducing the occurrence of cross-infection caused by inadequate cleaning.
[0004] However, in actual use, it was found that the device sprays alcohol cleaning solution through a conical cylinder and drives the mesh barrel to rotate through a motor, so that the instruments inside the mesh barrel come into contact with the rinsing solution at multiple angles to improve the cleaning effect.
[0005] However, the numerous dental instruments inside the mesh can collide with each other during rotation, which can easily lead to surface scratches. Long-term use will accelerate instrument wear and shorten their lifespan. Therefore, it is necessary to design a dental instrument cleaning device that is practical, easy to clean from multiple angles, and does not damage the instruments. Utility Model Content
[0006] The purpose of this invention is to provide a dental instrument cleaning device to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dental instrument cleaning device, comprising an outer shell, an inner cleaning shell fixedly installed near the center of the outer shell, a placement tray disposed inside the inner cleaning shell, two dental instrument forceps holders fixedly installed on the top surface of the placement tray, and multiple circular through holes opened on the top surface of the placement tray, an inlet pipe fixedly installed on the left side of the inner cleaning shell, the end of the inlet pipe away from the inner cleaning shell being connected to an external liquid supply pump, a circular air plate fixedly installed on the bottom surface of the inner cleaning shell, multiple exhaust pipes arranged in a circumferential array near the top outer surface of the circular air plate, an air pump fixedly installed on the right side of the outer shell, a circular filter cylinder fixedly installed on the right side of the outer shell above the air pump, the air inlet end of the air pump being fixed to the bottom end of the circular filter cylinder, and the exhaust end of the air pump extending into the interior of the inner cleaning shell and fixed to the outer surface of the circular air plate.
[0008] According to the above technical solution, a sealing cover is provided on the top surface of the inner cleaning shell, a second exhaust pipe is fixedly installed on the top surface of the sealing cover, and a plug is provided on the top surface of the second exhaust pipe.
[0009] According to the above technical solution, a waste liquid discharge pipe is fixedly installed on the bottom surface of the inner cleaning shell, one end of the waste liquid discharge pipe extends to the outside of the outer shell, and a valve is fixedly installed on the outer surface of one end of the waste liquid discharge pipe.
[0010] According to the above technical solution, a plurality of limiting protrusions are fixedly installed on the inner sidewall of the inner cleaning shell, and the bottom surface of the placement tray is in contact with the top surface of the limiting protrusions.
[0011] According to the above technical solution, a control panel is fixedly installed on the front side of the outer casing, and the air pump is electrically connected to the control panel.
[0012] According to the above technical solution, rectangular handles are fixedly installed on the left and right sides of the outer shell, respectively.
[0013] According to the above technical solution, handles are fixedly installed on the top surfaces of the placement tray and the sealing cover, respectively.
[0014] According to the above technical solution, an anti-slip support pad is fixedly installed on the bottom surface of the outer shell.
[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: During operation, the operator places the dental instruments to be cleaned on the dental instrument forceps, and injects disinfectant cleaning solution into the inner cleaning housing through an external pump to immerse the instruments. After starting the air pump, air is filtered through a circular filter cylinder and sent to a circular air plate with exhaust pipes arranged around its circumference. After the gas is released directionally through the pipes, it forms a dense cluster of bubbles in the liquid, triggering a turbulent rolling effect. The high-speed liquid flow penetrates the forceps and applies multi-directional dynamic shear force to the surface of the instruments. Combined with the micro-jet generated by the collapse of the bubbles, it penetrates deep into the gaps of the instruments to achieve rinsing and impact, effectively removing contaminants such as bloodstains and biofilms. This device replaces traditional mechanical contact cleaning with gas-liquid synergistic disturbance, ensuring 360° cleaning without dead angles while avoiding instrument collision and wear, thus improving the dual advantages of instrument cleaning and instrument protection.

The limiting protrusions 14 facilitate the support of the placement tray 3 and improve its stability. The handles 17 facilitate the removal and disassembly of the sealing cover 11 and the placement tray 3.
[0025] Please see Figure 1-4 Two dental instrument holders 4 are fixedly installed on the top surface of the placement tray 3. Multiple circular through holes 5 are provided on the top surface of the placement tray 3. A liquid inlet pipe 6 is fixedly installed on the left side of the inner cleaning housing 2. The end of the liquid inlet pipe 6 away from the inner cleaning housing 2 is connected to an external liquid supply pump. The dental instrument holders 4 facilitate the placement of various dental instruments. A limit bracket is provided on the dental instrument holders 4 to limit the placement of dental instruments and prevent them from tilting.

The circular through holes 5 facilitate the entry of liquid into the top of the placement tray 3 for cleaning and disinfection of instruments.
[0026] Please see Figure 1-4 A circular air plate 7 is fixedly installed on the bottom surface of the inner cleaning housing 2. Multiple exhaust pipes 8 are installed in a circumferential array near the top outer surface of the circular air plate 7. The circular air plate 7 and exhaust pipes 8 facilitate the subsequent discharge of gas, causing the disinfection and cleaning solution to tumble, thus improving the cleaning effect on dental instruments.
