Description

Technical Field

[0001] This utility model relates to the field of dental handpiece technology, and in particular to a cleaning holder for dental handpieces. Background Technology

[0002] A dental handpiece is a specialized tool used in oral medicine, primarily for drilling, grinding, and cutting teeth. It plays a crucial role in various dental treatments, including restorations, root canals, and extractions. It allows for the rapid and efficient preparation, grinding, and shaping of teeth, removal of diseased tissue, and cutting and separating. During dental procedures, the handpiece comes into contact with the patient's saliva, blood, and oral tissues. These fluids may contain various pathogens, and without thorough cleaning and disinfection, cross-infection can occur, increasing the patient's risk of contracting diseases. Therefore, a thorough cleaning of the handpiece is essential after each use. A cleaning holder can be used to automatically clean multiple handpieces, making it a highly efficient cleaning tool. Thus, a cleaning holder specifically designed for dental handpieces is particularly needed.

[0003] However, most existing dental handpiece cleaning holders use ceramic filters. When inserting the handpiece, the healthcare professional needs to forcefully push it into the retaining ring, during which the ceramic filter is easily broken. Some cleaning holders also have simpler handpiece fixing structures, which may cause the handpiece to shake during cleaning, also leading to filter breakage. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning holder for dental handpieces, addressing the issues raised in the background section regarding existing cleaning holders for dental handpieces. In most of these holders, the filter is made of ceramic, which is easily broken. The powder from the broken filter is washed into the dental handpiece by the water flow and remains inside the handpiece bearing, causing malfunctions. Furthermore, most cleaning holders have relatively simple fixing structures for the dental handpiece, which can cause the handpiece to shake during cleaning, further contributing to filter breakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning frame for dental handpieces, comprising a cleaning frame, mounting brackets fixedly installed on the inner walls of both sides of the cleaning frame, a cleaning plate fixedly connected to one end of the mounting bracket, a connecting bracket fixedly installed inside the cleaning plate, a communicating groove opened inside the connecting bracket, a cleaning seat fixedly installed at one end of the connecting bracket, a connecting pipe head installed inside the cleaning seat, a filter sheet installed inside the cleaning seat, a fixing member installed on the inner wall of the cleaning seat, a connecting block fixedly installed on the outer wall of the cleaning seat, a first fixing groove opened on one side surface of the connecting block, a connecting rod provided inside the connecting block, a second fixing groove opened on one side surface of the connecting rod, a pin inserted into one end of the connecting rod, and a fixing plate fixedly connected to one end of the connecting rod;

[0006] The filter sheet includes a protective layer, a filter layer, a dispersion layer, and a skeleton layer. The uppermost layer of the filter sheet is the protective layer, the lower side of the protective layer is the filter layer, the lower side of the filter layer is the dispersion layer, and the lower side of the dispersion layer is the skeleton layer.

[0007] Preferably, the lower end of the cleaning frame is fixedly equipped with a caster wheel, and the fixing component is a flexible rubber ring that is interference-fitted with the bottom of the dental handpiece.

[0008] Preferably, the mounting bracket and the cleaning plate are fixedly connected by bolts, and four sets of the connecting bracket are installed at equal intervals inside the cleaning plate.

[0009] Preferably, the surface of the connector head is provided with a connector groove for connecting a water pipe.

[0010] Preferably, the filter is made of stainless steel, and the skeleton layer has two layers.

[0011] Preferably, the first fixing groove and the second fixing groove are sized to match, and the second fixing groove is opened at equal intervals on the surface of the connecting rod.

[0012] Preferably, the fixed end of the pin matches the size of the first fixed groove, and one end of the pin can pass through the first fixed groove and the second fixed groove.

[0013] Preferably, one end of the connecting rod passes through the cleaning seat and the fixing member and is fixedly connected to the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This cleaning holder for dental handpieces, through the arrangement of a cleaning holder, mounting bracket, cleaning plate, connecting bracket, connecting groove, cleaning seat, connecting pipe head, filter, fixing component, connecting block, first fixing groove, connecting rod, second fixing groove, pin, fixing plate, and caster wheel, allows for easy cleaning of the dental handpiece. First, the lower end of the dental handpiece is placed into the cleaning seat. Then, the pin is removed and the connecting rod is pushed. The connecting rod, along with the fixing plate, clamps the dental handpiece. After clamping the handpiece, the pin is inserted into the first and second fixing grooves. This design secures the dental handpiece, preventing it from shaking and breaking the filter during cleaning. Furthermore, the stainless steel filter features a five-layer mesh structure, offering high strength, heat resistance, precision, and excellent filtration. It is also durable, preventing powder from breaking and being carried into the handpiece, thus avoiding damage. Additionally, the water pipe connects to the cleaning unit via a connecting groove and connector, facilitating automatic cleaning. Attached Figure Description

Through the setting of the pin 14, the pin 14 can pass through the second fixed groove 13 at different positions, thereby fixing the connecting rod 12 and the fixing plate 15 at different positions. This allows for the fixing of dental handpieces of different sizes, making it more practical.

[0030] Furthermore, one end of the connecting rod 12 passes through the cleaning seat 6 and the fixing member 9 and is fixedly connected to the fixing plate 15. With the setting of the connecting rod 12 and the fixing plate 15, the dental handpiece can be fixed when the connecting rod 12 and the fixing plate 15 move horizontally, preventing the dental handpiece from shaking during cleaning and causing damage to the filter 8.

[0031] Working principle: Before cleaning, the water pipe is connected to the cleaning seat 6 via the connecting groove 5 and the connecting pipe 7. During cleaning, the lower end of the dental handpiece is placed into the cleaning seat 6. At this time, the pin 14 is removed and the connecting rod 12 is moved horizontally. The connecting rod 12 will move the fixing plate 15 horizontally. The two fixing plates 15 move towards the middle at the same time to fix the dental handpiece, preventing the dental handpiece from shaking during the cleaning process and causing the filter 8 to break. Secondly, the movement of the connecting rod 12 allows the pin 14 to pass through the second fixing groove 13 at different positions. The fixing plate 15 can fix dental handpieces of different sizes, making it more practical. At the same time, the stainless steel filter 8 is equipped with a five-layer mesh structure. The filter 8 has high strength and high heat resistance, and the filtration accuracy is also very high. The filter 8 is not easy to break, which can prevent the powder generated by the breakage of the filter 8 from rushing into and remaining in the dental handpiece, preventing damage to the dental handpiece.
