Description

Technical Field

[0001] This invention relates to the field of dental disease treatment technology, and in particular to a combined teeth cleaning and saliva suction device. Background Technology

[0002] Teeth cleaning, commonly known as scaling, refers to the removal of tartar, plaque, and stains from the teeth using specialized instruments, followed by polishing to delay the re-deposition of plaque and tartar. Teeth cleaning can be categorized into ultrasonic scaling and air polishing based on their working principles. Ultrasonic scaling utilizes the mechanical, thermal, and cavitation effects of high-frequency vibrations to break down tartar, which is then cleaned with a water mist. Air polishing uses compressed gas (usually air) to propel abrasive powder onto the tooth surface, where it mixes with a liquid medium (usually water) to clean the tooth surface. During teeth cleaning, water mist, debris, blood, and saliva are generated in the patient's mouth. A suction device is typically used to remove these substances to maintain a clear view of the patient and ensure the smooth progress of the dental procedure.

[0003] Existing dental cleaning products typically do not include saliva suction functionality. Saliva is usually suctioned using the saliva suction device that comes with the dental chair. However, during the off-season for dental cleaning and when the frequency of daily use is low, the daily maintenance and disinfection costs of the dental chair will increase significantly. In addition, dental chairs are integrated systems, and some dental chairs that use positive pressure air sources to generate negative pressure suction usually do not have solid-liquid separation. The valves or pipes in the saliva suction system are prone to blockage and are not easy to repair. Summary of the Invention

[0004] The purpose of this invention is to provide a teeth cleaning and saliva suction integrated machine, which aims to solve the problems of existing teeth cleaning products not having solid-liquid separation, and the valves or pipes in the saliva suction system being prone to blockage and difficult to maintain.

[0005] To achieve the above objectives, the present invention provides a dental cleaning and saliva suction integrated machine, comprising a dental cleaning main unit, an operating end, an air source interface, a saliva suction assembly, a dental cleaning working end, a saliva suction working end, and a foot switch. The dental cleaning main unit is connected to the operating end, the air source interface, the saliva suction assembly, the dental cleaning working end, and the foot switch, respectively. The saliva suction working end is connected to the saliva suction assembly. The saliva suction assembly includes a saliva suction main board, a negative pressure generator, a pre-filter, a liquid collector, a filter, a first solenoid valve, a second solenoid valve, a clamp valve, and a first one-way valve. The negative pressure generator includes a strong suction valve and a weak suction valve. The saliva suction main board is connected to the operating end. The inlet end of the strong suction valve is connected to the first solenoid valve, and the outlet end is connected to the first one-way valve. The inlet end of the weak suction valve is connected to the second solenoid valve, and the outlet end is connected to the second one-way valve. The pre-filter is connected to the vacuum ends of the saliva suction working end, the strong suction valve, and the weak suction valve, respectively. The liquid collector is connected to the first one-way valve, the second one-way valve, the pinch valve, and the filter, respectively.

[0006] The saliva suction working end includes a flexible tube and a saliva suction head, wherein the flexible tube is connected to the saliva suction head and is located on one side of the saliva suction head.

[0007] The saliva suction head includes an upper bite pad, a lower bite pad, a saliva suction tube, a bite pad connector, an O-ring, a worm gear, a turbine, a movable rod, and a movable rod connector.

The O-ring is disposed between the saliva suction tube and the upper bite pad for sealing. The turbine, the worm gear, and the movable rod connector are all disposed on the upper bite pad.

[0008] The turbine component includes a turbine support, a turbine body, a turbine mounting base, and a auger cap. The turbine mounting base is threadedly connected to the lower engagement pad. The turbine body is disposed on one side of the turbine support, and the turbine mounting base is disposed on the side of the turbine body away from the turbine support. The auger cap is rotatably disposed on the turbine mounting base.

[0009] The worm gear component includes a worm support, a worm body, a sleeve, and a worm fixing seat. The worm body is rotatably connected to the turbine body and is located on one side of the turbine body. The sleeve is sleeved on the worm body. The worm support is located on one side of the worm body. The worm fixing seat is located on the side of the worm body away from the worm support.

[0010] The operation terminal allows for relevant operation settings via screen, slider, or buttons.

[0011] This invention discloses a dental cleaning and saliva suction integrated device. The water output of the dental cleaning working end is adjustable and controlled by a foot switch. The saliva suction mainboard is connected to the operating end, allowing for settings of saliva suction and drainage. (The saliva suction mode can be set with one button on the operating end. The operating end control methods include, but are not limited to, screen touch control, touch control, or button control. When the operating end is a screen, the page displays three modes. Modes one and two can be directly selected to complete the setting. Selecting mode three will bring up a selection of strong suction, weak suction, and saliva suction frequency settings. When the operating end is a touch panel, the panel includes a frequency adjustment slider and mode buttons. The saliva suction mode is switched by pressing the mode buttons.) Includes Mode 1, Mode 2, Mode 3 (strong suction), and Mode 3 (weak suction). The panel displays indicator lights when different modes are selected. After selecting Mode 3, the suction frequency can be adjusted using the frequency adjustment slider. When the operation is via buttons: the panel includes frequency increase / decrease buttons and mode buttons. Mode selection is consistent with touch control. When Mode 3 is selected, the suction frequency is adjusted using the increase / decrease buttons. The suction modes are as follows: 1. Controlled by the foot switch, both the teeth cleaning end and the suction end operate simultaneously; 2. Suctioning at a certain frequency and time interval according to the set water output; 3. Customer-customized (strong suction, weak suction, and suction frequency can be selected according to user habits). During drainage, the drainage frequency can be automatically adjusted according to the set suction mode. The pre-filter is located at the vacuum end of the strong suction valve and the weak suction valve, mainly used for solid-liquid separation. It is placed outside the main unit of the dental cleaning machine, making it easy to clean and maintain, reducing the probability of pipe blockage and reducing maintenance costs. The liquid collector is used for gas-liquid separation and collects liquid. The outlet of the drainage pipe is located at the bottom of the liquid collector and is controlled by the clamp valve. The filter is located at the rear end of the liquid collector. The filter is filled with filter material, which can adsorb aerosols in the gas and remove odors. The gas can be directly discharged after passing through the filter. This solves the problem that existing dental cleaning products do not have solid-liquid separation and that valves or pipes in the suction system are prone to blockage and difficult to repair.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The integrated design of the dental cleaning suction system eliminates the need for the suction system to pass through the dental chair passage, reducing the daily maintenance and sterilization costs of the dental chair during the off-season. It also includes a separate solid-liquid separator, lowering the probability of pipe blockage and reducing maintenance costs. The adjustable suction tip integrates the auxiliary opening with the suction, making it suitable for patients of different ages and freeing up manpower for suction nurses.

[0027] Furthermore, the turbine component 627 includes a turbine support 6271, a turbine body 6272, a turbine mounting base 6273, and a auger cap 6274. The turbine mounting base 6273 is threadedly connected to the lower engagement pad 622. The turbine body 6272 is disposed on one side of the turbine support 6271, and the turbine mounting base 6273 is disposed on the side of the turbine body 6272 away from the turbine support 6271. The auger cap 6274 is rotatably mounted on the turbine body 6272. The worm gear component 626 is mounted on the turbine mounting base 6273. The worm gear component 626 includes a worm support 6261, a worm body 6262, a sleeve 6263, and a worm mounting base 6264. The worm body 6262 is rotatably connected to the turbine body 6272 and is located on one side of the turbine body 6272. The sleeve 6263 is sleeved on the worm body 6262. The worm support 6261 is located on one side of the worm body 6262. The worm mounting base 6264... 4 is located on the side of the worm gear body 6262 away from the worm gear support 6261; the saliva suction working end 6 includes a flexible hose 61 and a saliva suction head 62, the flexible hose 61 is connected to the saliva suction head 62 and is located on one side of the saliva suction head 62; the saliva suction head 62 includes an upper biting pad 621, a lower biting pad 622, a saliva suction tube 623, a biting pad connector 624, an O-ring 625, a worm gear component 626, a turbine component 627, a movable rod 628, and a movable rod. The connector 629 is used to rivet the upper bite pad 621 and the lower bite pad 622 together and is located on one side of the lower bite pad 621. The saliva suction tube 623 is disposed between the upper bite pad 621 and the lower bite pad 622. The O-ring 625 is disposed between the saliva suction tube 623 and the upper bite pad 621 and serves as a seal. The turbine component 627, the worm gear component 626 and the movable rod connector 629 are all disposed on the upper bite pad 621.

[0028] In this embodiment, the upper engagement pad 621 and the lower engagement pad 622 are riveted together by the engagement pad connector 624. The movable rod 628 is riveted to the upper engagement pad 621 and the worm gear member 626 respectively by two movable rod connectors 629. The movable rod 628 serves as a limiting element. The turbine body 6272 fixing seat has external threads and is threadedly connected to the lower engagement pad 622. The turbine body 6272 is installed inside the lower engagement pad 622 via the turbine support 6271 and the fixing seat. The sleeve 6263 is fitted onto the outside of the worm gear body 6262. The worm gear 626 is fixed in the same way as the turbine 627. The turbine 627 is placed at a 90-degree angle to the worm gear 626. By rotating the spiral cap 6274 on the turbine 627, the turbine body 6272 rotates, causing the worm gear body 6262 to rotate, which in turn causes the sleeve 6263 on the worm gear body 6262 to shift, thereby adjusting the opening degree of the upper bite pad 621 and the lower bite pad 622. The suction tube 623 contains a snap-fit ​​structure. After the upper bite pad 621 and the lower bite pad 622 are riveted together by the bite pad connector 624, they are inserted into the bite pad connector 624 from both sides and snapped together internally. The O-ring 625 serves to seal and provide resistance, so that the suction tube 623 has a certain resistance when rotating. The opening can also be adjusted using the adjusting screw 6302, as described above. Figure 7 , Figure 8 As shown, the adjusting screw 6302 is installed on the lower occlusal pad 622 via the adjusting screw support 6301 and the adjusting screw fixing seat 6304. The adjusting screw fixing seat 6304 has external threads and is fixed to the lower occlusal pad 622 by threaded connection. The adjusting screw sleeve 6303 is fitted over the adjusting screw 6302. The adjusting screw cap 6274 is interference-fitted to the adjusting screw 6302. By rotating the adjusting screw cap 6274, the adjusting screw 6302 is rotated, causing the adjusting screw sleeve 6303 to shift, thereby adjusting the mouth opening. The saliva suction tube 623 has two suction ends, located on the tongue side and buccal side respectively after the patient wears it. The end of the saliva suction tube 623 has multiple suction holes, which can distribute pressure and reduce the probability of damage to the patient's oral mucosa. The saliva suction tube 623 can be rotated after installation, which facilitates fine adjustment of the suction position. When the operator has finished cleaning one side of the molars and needs to clean the other side, the saliva suction head 62 is inverted so that the end connected to the flexible tube 61 faces outwards from the mouth, and then the saliva suction head 62 is rotated and adjusted to a suitable position.

[0029] To better understand this technical solution, the following embodiments are provided for further explanation: When the dental cleaning unit 1 includes air blasting, dental cleaning and saliva suction can share the same air source. The inlet ends of the strong suction valve 421 and the weak suction valve 422 are respectively connected to the first solenoid valve 46 and the second solenoid valve 49. The first solenoid valve 46 and the second solenoid valve 49 are normally closed, controlling the opening and closing of the strong suction valve 421 and the weak suction valve 422. The outlet ends are respectively connected to the first one-way valve 48 and the second one-way valve 410 to prevent liquid circuit failure or backflow. The vacuum end is connected to the pre-filter 43, which plays a solid-liquid separation role and reduces the probability of blockage in the saliva suction system pipes and valves. The clamp valve 47 is connected to the bottom outlet end of the liquid collector 44, and the upper outlet end of the liquid collector 44 is connected to the filter 45. The gas is discharged after being filtered by the filter 45.

[0030] The suction function includes strong suction and weak suction, which can be selected through the operation terminal 2. There are three ways to control the suction opening and closing: First, it is controlled by the foot switch 7. When the foot switch 7 is pressed, the teeth cleaning working end 5 starts to work to perform teeth cleaning. At the same time, the first solenoid valve 46 or the second solenoid valve 49 works, changing from normally closed to normally open. Compressed gas enters the strong suction valve 421 or the weak suction valve 422, generating negative pressure suction, and the suction working end 6 starts to work. The first one-way valve 48 or the second one-way valve 410 can prevent compressed gas from failing to enter the strong suction valve 421 or the weak suction valve 422, thus preventing liquid circuit failure or backflow; Second, by setting the amount of dental cleaning water, spontaneous saliva suction is performed at a certain frequency. Assuming that the amount of dental cleaning water is divided into three levels, with the amount of water gradually increasing from level 1 to level 3, the saliva suction main board 41 controls the time and time interval for opening and closing the first solenoid valve 46 or the second solenoid valve 49 each time, thereby controlling the saliva suction frequency and saliva suction volume; Third, through the customization of the operation terminal 2, it can be used for continuous saliva suction or to customize the saliva suction frequency according to experience and preference.

[0031] The saliva suction head 62 integrates auxiliary opening and suction functions. Its opening degree can be adjusted via the screw cap 6274 to fit the patient's oral cavity. The saliva suction head 62 is connected to the flexible tubing 61, improving patient comfort. During dental cleaning, patients typically adopt a supine or semi-recumbent position. In this position, the lingual and buccal sides of the molars are where water, blood, and debris accumulate during cleaning. The two suction ends of the saliva suction tube 623, after being worn by the patient, are located on the lingual and buccal sides of the molars, respectively, allowing for targeted suction. The screw cap 6274, used to adjust the opening degree of the saliva suction head 62, is riveted to the side of the saliva suction head 62 for easy adjustment by the operator. Before starting the teeth cleaning, place the flexible tube 61 with the end facing outwards on one molar side and clean the other teeth except the molar covered by the suction head 62. After cleaning, remove the suction head 62, invert it, place the flexible tube 61 with the end facing outwards on the other molar side, adjust the position of the suction head 62, and then clean the remaining teeth.

[0032] The above-disclosed embodiments are merely preferred embodiments of a teeth cleaning and saliva suction device of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
