The fixing rod 107 forms an elastic structure with the first spring 108 and the metal shell 106.

[0022] Please see Figure 4 The dental tool disinfection device shown includes an external protective component 2 comprising a protective box 201. A hinge 202 is fixedly connected to one side of the protective box 201, and a cabinet door 203 is fixedly connected to the other side of the hinge 202. A buckle 204 is fixedly connected to the top of the cabinet door 203. A metal shell 205 is fixedly connected to the other side of the protective box 201.

The cabinet door 203 and the protective box 201 form a rotating structure through the hinge 202. The cabinet door 203 is made of high-temperature resistant PC. The cabinet door 203 and the buckle 204 are integrated. The buckle 204 and the plug rod 207 form an engaging structure. The plug rod 207 and the metal shell 205 form an elastic structure through the second spring 206.

[0023] Please see Figure 5 The dental tool disinfection device shown includes a support assembly 3 comprising a threaded rod 301, an inner threaded rod 302 threaded to the outer wall of the threaded rod 301, a support plate 303 fixedly connected to the bottom of the inner threaded rod 302, and a rubber pad 304 fixedly connected to the bottom of the support plate 303; the threaded rod 301 and the inner threaded rod 302 are arranged with their vertical central axes coincident, and the support plate 303 forms a lifting structure with the threaded rod 301 through the inner threaded rod 302.

[0024] Working Principle: Before sterilizing dental tools, the equipment is first stably deployed using the support assembly 3. The threaded rod 301 and the inner threaded rod 302 in the support assembly 3 are aligned vertically. Medical personnel can rotate the inner threaded rod 302 according to the clinic's floor flatness or operating height requirements. Utilizing its threaded connection with the threaded rod 301, this adjusts the height of the support plate 303 at the bottom. Clockwise rotation of the inner threaded rod 302 moves it downwards along the outer wall of the threaded rod 301, lowering the support plate 303 accordingly; counterclockwise rotation raises the support plate 303 until the entire equipment remains level and stable. At this point, the rubber pad 304 at the bottom of the support plate 303 is in close contact with the ground, increasing friction to prevent the equipment from sliding during use and providing stable support for subsequent sterilization operations. After the equipment stabilizes, the placement of the tools to be disinfected begins. This process relies on the sliding and fixing structure of the multi-layer drawer-type component 1. The support rod 101 of the multi-layer drawer-type component 1 is the core support component. The sliding groove 104 at its top and the slider 102 form a sliding fit. The slider 102 and the disinfection tray 103 are integrated. Medical staff can hold the edge of the disinfection tray 103 and pull it outward along the sliding groove 104. At this time, the limiting rod 109 integrated on the side of the slider 102 will slide synchronously along the limiting groove 105. The limiting groove 105 constrains the movement trajectory of the limiting rod 109, preventing the disinfection tray 103 from shifting or falling off during the pulling process. After dental tools such as forceps, probes, and dental handpieces are placed in the sterilization tray 103, they are secured by an elastic fixing structure consisting of a metal shell 106, a first spring 108, and a fixing rod 107. Pressing the fixing rod 107 compresses the first spring 108 inside the metal shell 106, causing it to move downwards. Once the tool is in place, releasing the fixing rod 107 allows the first spring 108 to return to its original shape, generating an upward elastic force that pushes the fixing rod 107 against the tool surface. This securely fixes tools of different sizes within the sterilization tray 103, preventing them from shifting and affecting the sterilization process. After securing the tools, the sterilization tray 103 is pushed back to its original position along the slide groove 104. At this point, the storage and securing of the multi-layer drawer-type component 1 is complete. Next, the disinfection environment is sealed using the external protective component 2. The protective box 201 within the external protective component 2 provides external protection for the multi-layer drawer-type component 1. Medical personnel push the cabinet door 203, causing it to rotate around the protective box 201 via the hinge 202 until it closes. The cabinet door 203 is made of high-temperature resistant PC material, ensuring high-temperature resistance during the disinfection process while also facilitating observation of the internal disinfection status by medical personnel. When the cabinet door 203 closes, the integrated buckle 204 at its top presses against the insert rod 207 inside the metal outer shell 205, causing the insert rod 207 to compress the second spring 206 and move downwards. When the buckle 204 moves to the position corresponding to the insert rod 207, the second spring 206 returns to its original shape, pushing the insert rod 207 upwards to reposition itself, forming a tight engagement with the buckle 204. This firmly secures the cabinet door 203, ensuring a sealed space inside the protective box 201, preventing ozone leakage during disinfection, and simultaneously isolating it from external contamination. Once the sealed environment is established, the equipment disinfection program is initiated. At this time, the ozone generator 4 at the bottom of the multi-layer drawer-type component 1 starts working, generating ozone gas with strong oxidizing properties. The ozone diffuses evenly within the sealed space of the protective box 201, penetrating to the surface and crevices of each tool in the disinfection tray 103, achieving sterilization and disinfection by destroying the cell membranes, proteins, and other structures of microorganisms. Simultaneously, the disinfection lamp 110 fixedly connected inside the disinfection tray 103 is turned on, releasing disinfection light such as ultraviolet light, which works synergistically with ozone to further enhance the disinfection effect, ensuring a high kill rate of various pathogenic microorganisms such as bacteria, viruses, and spores, and avoiding disinfection dead spots. During the disinfection process, medical personnel can observe the disinfection status of the tools inside through the high-temperature resistant PC material cabinet door 203, monitoring the disinfection progress without opening the cabinet door 203, reducing the risk of disinfection interruption or contamination caused by opening the door. After the disinfection process is completed, the ozone generator 4 stops working. Once the ozone concentration inside the equipment drops to a safe level, medical staff press the insert rod 207 in the external protective component 2, causing it to compress the second spring 206 and move downwards, disengaging from the latch 204. Then, the cabinet door 203 is opened by rotating the hinge 202. Next, the disinfection tray 103 is pulled outwards along the slide 104, and the slider 102 and the limiting rod 109 slide along the slide 104 and the limiting groove 105 respectively, allowing the disinfected tools to be removed. If continuous disinfection is required, the above process of "placing tools - closing the cabinet door 203 - starting disinfection - removing tools" can be repeated. Utilizing the multi-layer design of the multi-drawer component 1, efficient disinfection of multiple batches of tools can be achieved, meeting the high-frequency tool disinfection needs of dental clinics.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
