[0002] Oral disinfection and cleaning devices used in dentistry are specifically designed to meet the needs of efficient cleaning and disinfection of the oral cavity during dental treatment. The purpose is to effectively remove bacteria and other microorganisms in the oral cavity, reduce the risk of infection, and create a cleaner working environment for subsequent treatment. The aim is to ensure that it can effectively perform cleaning and disinfection tasks while ensuring the safety and comfort of patients.

[0003] Existing oral disinfection and cleaning devices use fine nozzles to evenly spray disinfectant into the inside of the mouth, ensuring that every corner is covered. To adapt to the needs of different patients and different treatment scenarios, these devices are usually equipped with an adjustable pressure control system to avoid damage to the soft tissues of the mouth. Different disinfectants can be used as needed. The handheld part is usually designed to be very ergonomic so that dentists can remain comfortable even when using it for a long time.

[0004] In practical use, existing technologies often cause problems because operators move the disinfectant delivery pipe when using the handheld nozzle for disinfection. The long and loose pipe is prone to tangling or getting stuck, posing a safety hazard. Furthermore, cleaning up the extra pipe increases the workload for the operator. Therefore, a dental disinfection and cleaning device for oral cavity is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides an oral disinfection and cleaning device for endodontics. It uses a water pump connected to a flexible tube to deliver disinfectant or cleaning solution from the storage chamber to a handheld nozzle. The operator uses the handheld nozzle to rinse and disinfect the patient's oral cavity. Moving the handheld nozzle pulls the flexible tube outward from the storage chamber and compresses the push plate, causing the telescopic rod and spring to retract, thus controlling the length of the flexible tube. Conversely, the spring's elasticity resets the push plate, automatically retracting the flexible tube into the storage chamber. This design not only avoids the problem of messy flexible tubes but also makes the entire device look neater and reduces safety hazards caused by improperly placed flexible tubes.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides an oral disinfection and cleaning device for dentistry, including a disinfection box 1. The upper surface of the disinfection box 1 has a liquid inlet hole 102. A piston 103 is movably connected to the inner cavity of the liquid inlet hole 102. A rinsing assembly 2 is installed in the inner cavity of the disinfection box 1, including a partition 201 fixedly connected to the inner cavity of the disinfection box 1. A flexible tube 204 is connected to one side of the partition 201. One end of the flexible tube 204 passes through the disinfection box 1 and is connected to a handheld nozzle 205. A push plate 207 is abutted against the outer surface of the flexible tube 204. A telescopic rod 206 is fixedly connected to one side of the push plate 207. A spring 208 is sleeved on the outer surface of the telescopic rod 206.

[0030] Specifically, multiple brake casters 101 are evenly installed on the lower surface of the disinfection box 1. The partition 201 divides the inner cavity of the disinfection box 1 into a liquid storage chamber 202 and a pipe storage chamber 203. The hose 204 is located in the pipe storage chamber 203. The end of the telescopic rod 206 away from the push plate 207 is fixedly connected to the inner wall of the disinfection box 1. One end of the spring 208 is fixedly connected to the push plate 207, and the other end of the spring 208 is fixedly connected to the inner wall of the disinfection box 1. The push plates 207 are staggered inside the pipe storage chamber 203.

[0031] Furthermore, when it is necessary to rinse the inside of the oral cavity, the water pump 305 connected to the hose 204 is started to deliver the disinfectant or cleaning solution in the reservoir 202 to the handheld nozzle 205 through the hose 204. The operator then uses the handheld nozzle 205 to rinse and disinfect the inside of the patient's oral cavity.

[0032] When the operator moves the handheld nozzle 205, it pulls the hose 204 outward from the pipe storage chamber 203 and squeezes the push plate 207, causing the telescopic rod 206 and spring 208 to retract, thereby controlling the length of the hose 204. Conversely, the spring 208's own elasticity drives the push plate 207 to reset, causing the hose 204 to automatically retract into the pipe storage chamber 203. The spring 208 helps to reset when not in use. This design not only avoids the problem of messy hoses, but also makes the whole device look neater and reduces safety hazards caused by messy hose placement.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. A cleaning component 3 is installed on the upper surface of the disinfection box 1, including a cleaning frame 301 fixedly connected to the upper surface of the disinfection box 1. Two pipe clamps 302 are evenly fixedly connected to the bottom of the inner cavity of the cleaning frame 301. A rinsing pipe 304 is fixedly connected to the inner cavity of the disinfection box 1.

[0035] Specifically, a water pump 305 is installed on both the hose 204 and the flushing pipe 304 at one end of the liquid storage chamber 202. The upper end of the flushing pipe 304 is directly opposite the nozzle end of the handheld nozzle 205, which is located inside the pipe clamp 302. A drain pipe 303 is connected to one side of the cleaning frame 301.

[0036] Furthermore, the cleaning frame 301 is used to store the handheld nozzle 205 so that it can be neatly placed when not in use. Two tube clamps 302 are evenly distributed at the bottom of the cleaning frame 301 to clamp and fix the handheld nozzle 205 and make it easy to access. The rinsing tube 304 is located in the liquid storage chamber 202 and is powered by another water pump 305 to deliver the cleaning liquid to the handheld nozzle 205 to rinse and disinfect the handheld nozzle 205 itself.

[0037] The drain pipe 303 is used to discharge the waste liquid after use to the trash can, effectively managing the discharge of waste liquid and maintaining the cleanliness and hygiene of the working environment. This not only helps to maintain a good treatment environment, but also facilitates subsequent cleaning work. Multiple brake casters 101 are installed on the lower surface of the disinfection box 1, which allows the entire device to be easily moved to different treatment positions. When it is necessary to fix the position for operation, the wheels can be locked by braking to ensure that the equipment is stable and does not move, which increases the convenience and safety of use.

[0038] Working principle: When the oral cavity needs to be rinsed during use of the device, the water pump 305 connected to the hose 204 is activated. The disinfectant or cleaning solution in the storage chamber 202 is delivered to the handheld nozzle 205 through the hose 204. The operator uses the handheld nozzle 205 to rinse and disinfect the patient's oral cavity. When the operator moves the handheld nozzle 205, it pulls the hose 204 outward from the storage chamber 203, squeezing the push plate 207, causing the telescopic rod 206 and spring 208 to retract, thus controlling the length of the hose 204. Conversely, the spring 208's own elasticity resets the push plate 207, causing the hose 204 to automatically retract to its original length. The function of the spring 208 in the pipe storage chamber 203 is to help reset the pipes when not in use, so as to avoid the pipes being messy and disorderly. The cleaning frame 301 is used to store the handheld nozzle 205 so that it can be neatly placed when not in use. Two pipe clamps 302 are evenly distributed at the bottom of the cleaning frame 301 to clamp and fix the handheld nozzle 205 and make it easy to access. The rinsing pipe 304 is located in the liquid storage chamber 202 and is powered by another water pump 305 to deliver the cleaning solution to the handheld nozzle 205 to rinse and disinfect the handheld nozzle 205 itself. The drain pipe 303 is used to discharge the waste liquid after use to the trash can. The disinfection box 1 can be moved to different treatment positions by the brake casters 101.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
