[0002] Dental scalers are core equipment in dental clinics. They remove plaque, tartar, and stains from the tooth surface through ultrasonic vibrations, while also performing periodontal cleaning and polishing functions. They are a key tool for preventing periodontal disease and improving oral hygiene. As a medical device, dental scalers must use pure water or sterile water that meets standards.
[0003] Chinese Patent Publication No. CN 203291055 U discloses an automatic water supply system for an ultrasonic scaler, including a water storage bottle. The water storage bottle is connected to the water path of the ultrasonic scaler handle via a pipeline. A diaphragm pump and a solenoid valve are sequentially arranged on the water path connecting the water storage bottle and the ultrasonic scaler handle.
[0004] The automatic water supply system of the aforementioned ultrasonic scaler uses a water storage bottle to supply water to the handle through a pipe. However, as a medical device, the water used by the scaler must be pure water or sterile water that meets the standards. Moreover, the water in the water storage component generally remains for a long time (≤24 hours). Therefore, the water in the water storage component may breed bacteria and fungi and form a biofilm. The aforementioned water supply system cannot disinfect the water in the water storage component in real time, so it cannot avoid the growth of bacteria and fungi. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-7 In this embodiment of the utility model, it includes
[0031] Water tank 3, used to store sterile water, is located at the top of one end of the casing 2; a cover 4 is connected to the top of the water tank 3; the water tank includes a body 31, and an ultraviolet lamp strip 34 is provided on the body 31.
[0032] The bottom of the suction head 8, located inside the housing 31, is connected to the screw barrel 5. The end of the screw barrel 5 away from the suction head 8 extends to the outside of the housing 31 and is connected to the anti-backflow valve 9.
[0033] The end of the anti-backflow valve 9 away from the screw barrel 5 is connected to the anti-backflow valve 10. The end of the anti-backflow valve 10 away from the anti-backflow valve 9 is connected to the input end of the DC pump 11 through a hose. The output end of the DC pump 11 is fixedly connected to the connecting pipe 12. The end of the connecting pipe 12 away from the DC pump 11 is connected to the ultrasonic scaler handle 13.
[0034] The bottom of the housing 31 is fixedly connected to the top of the casing 2, and the top of the housing 31 is connected to the cover 4. A lead tube 32 is sealed and fixedly connected to the inside of the housing 31, and the lead tube 32 corresponds to the position of the circuit board 16.
[0035] The top of the box 31 is provided with a sealing groove 33 with the same cross-sectional shape as the box 31, and the top of the lead tube 32 is connected to the sealing groove 33; the ultraviolet lamp strip 34 is fixedly connected inside the sealing groove 33.
[0036] The lead tube 32 contains an electronic wire. One end of the electronic wire is electrically connected to the circuit board 16, and the other end of the electronic wire extends along the lead tube 32 into the sealing groove 33 and is electrically connected to the ultraviolet lamp strip 34.
[0037] By adopting the above technical solution, by setting a sealing groove 33 on the tank body 31 of the water tank 3 and installing an ultraviolet lamp strip 34 in the sealing groove 33, the short-wave ultraviolet light generated by the ultraviolet lamp strip 34 can be used to sterilize the water stored in the tank body 31 in real time. This can effectively prevent the growth of bacteria and fungi in the water, ensure that the dental cleaning machine uses sterile water that meets the standards, and improve the safety and hygiene of the dental cleaning machine when used as a medical device.
[0038] Furthermore, the lead tube 32 serves to protect the electronic wire, allowing it to extend inside the housing 31 to the ultraviolet lamp strip 34. This prevents the electronic wire from being exposed to the outside environment and from coming into contact with water, ensuring that the electronic wire can function normally.
[0039] In this embodiment, the bottom of the housing 31 is provided with a through hole for the screw cylinder 5 to pass through. Both sides of the through hole are provided with sealing gaskets 6, one of which is located inside the housing 31 and the other is located outside the housing 31. Both sealing gaskets 6 are coaxially sleeved on the outside of the screw cylinder 5. A nut 7 is threadedly connected to the outer side of the screw cylinder 5 near the sealing gasket 6. The bottom of the nut 7 fits against the sealing gasket 6 located inside the housing 31.
[0040] The screw barrel 5 is integrally provided with a convex ring at one end outside the housing 31. The sealing gasket 6 located outside the housing 31 is located between the convex ring of the housing 31 and the screw barrel 5, and one side of the sealing gasket 6 is in contact with the convex ring, while the other side of the sealing gasket 6 is in contact with the outer wall of the housing 31.
[0041] By adopting the above technical solution, the reasonable connection of components such as the suction head 8, screw barrel 5, anti-backflow valve 9, anti-backflow valve 10, and DC pump 11 ensures the normal flow of water, avoids water backflow and backflow problems, and guarantees the stable operation of the dental cleaning machine.
[0042] Furthermore, the sealing gasket 6 serves to seal, preventing water in the housing 31 from flowing out through the through hole at the bottom of the housing 31, and also preventing external bacteria and fungi from entering the housing 31 through the through hole at the bottom of the housing 31; the nut 7, in conjunction with the convex ring of the screw cylinder 5, can clamp the two sealing gaskets 6, so that the two sealing gaskets 6 can only fit against the inner and outer walls of the housing 31, further improving the sealing effect of the sealing gaskets 6.
[0043] In this embodiment, the bottom of the housing 2 is fixedly connected to a bottom shell 1. The bottom shell 1 has a battery 15 and a circuit board 16 inside the end near the box 31, and the circuit board 16 is electrically connected to the battery 15. The bottom shell 1 is rectangular, and the side of the bottom shell 1 near the DC pump 11 has a through hole for the connecting pipe 12 to pass through.
[0044] Two mounting brackets 14 for placing ultrasonic scaling handles 13 are symmetrically fixedly connected to the end of the housing 2 away from the water tank 3; the box body 31 is made of transparent material, and a water level scale is provided on the outer wall of one end of the box body 31. The length of the box body 31 is less than the width of the housing 2; the DC pump 11 is located inside the bottom shell 1 and is fixedly connected to the bottom shell 1. The DC pump 11 is electrically connected to the battery 15.
[0045] By adopting the above technical solution, the battery 15 and circuit board 16 set in the bottom shell 1 provide stable power support for components such as the ultraviolet lamp strip 34 and the DC pump 11. The entire mechanism is compact and reasonable, and the components work together to better meet the needs of dental clinics for dental scalers.
[0046] The working principle of this utility model is as follows: by setting a sealing groove 33 on the tank body 31 of the water tank 3 and installing an ultraviolet lamp strip 34 in the sealing groove 33, the short-wave ultraviolet light generated by the ultraviolet lamp strip 34 can sterilize the water stored in the tank body 31 in real time. This can effectively prevent the growth of bacteria and fungi in the stored water, ensure that the dental cleaning machine uses sterile water that meets the standards, and improve the safety and hygiene of the dental cleaning machine when used as a medical device.
[0047] The proper connection of components such as the suction head 8, screw barrel 5, anti-backflow valve 9, anti-backflow valve 10, and DC pump 11 ensures the normal flow of water, avoids backflow and backflow problems, and guarantees the stable operation of the dental cleaning machine.
