Description

Technical Field

[0001] The utility model relates to the technical field of dental medical instruments, in particular to a quick-connect sterilizable three-purpose dental handpiece. Background Art

[0002] The three-in-one dental handpiece used by dentists is provided with high-pressure gas and high-pressure pure water through the dental treatment machine. The three-in-one dental handpiece nozzle sprays them on the treatment area separately or in combination, and then removes the substances produced by the treatment to achieve the cleaning effect.

[0003] Existing three-in-one dental handpieces are directly connected to the pipeline and are not sterilized after use, which can easily become a source of infection and pose a health risk to patients. Furthermore, due to their structure, three-in-one dental handpieces are large and heavy, making prolonged operation more laborious for doctors.

[0004] Therefore, the current three-purpose dental handpiece is not very scientific and its structure is not very reasonable. These need to be improved. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the above technical difficulties and provide a quick-connect sterilizable three-purpose dental handpiece, which can be quickly removed for sterilization during use, and has changed the structure and materials so that the doctor can observe the treatment area more clearly.

The water channel and the air channel in the quick connector are respectively connected to the water channel and the air channel in the quick connector.

[0012] As an improvement, the quick connector head is formed with a male adapter that is detachably connected to the quick connector base. After the quick connector and the quick connector base are connected, the two are connected and fixed together by a quick connector locking device provided on the quick connector, making the quick connector and the quick connector base convenient to connect.

[0013] As an improvement, the tail of the quick connector is provided with a threaded connector, and the tail end is provided with a sealing rubber pad, which plays a role in sealing between the rear of the quick connector and the pipeline connector of the dental treatment machine.

[0014] As an improvement, the tail end of the quick connector is further provided with a water inlet and an air inlet.

[0015] The advantages of this utility model compared with the prior art are:

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Quick-connect sterilizable three-in-one dental handpiece, including:

[0028] The handpiece 1 includes a handpiece body 11, a nozzle quick-change device 12, and a water-gas switch 13. The nozzle quick-change device 12 and the water-gas switch 13 are respectively mounted on the inner side of the handpiece body 11. The water-gas switch 13 includes a water pressure control switch and an air pressure control switch. The nozzle 2 is detachably mounted in the nozzle quick-change device 12. The handpiece body 11 is made of lightweight aluminum alloy and has an improved press-switch method, allowing the doctor to more clearly observe the treatment area, making it more convenient and easier to use.

[0029] The machine handle housing 3 and the quick-connect seat 4; the tail end of the machine head body 11 is connected to the quick-connect seat 4 through the machine handle housing 3, and the machine handle housing 3 is respectively threadedly connected to the quick-connect seat 4 and the machine head body 11;

[0030] The quick connector 5 is detachably mounted on the quick connector base 4. The head end of the quick connector 5 is formed with a convex adapter 51 that is detachably connected to the quick connector base 4. After the quick connector 5 is connected to the quick connector base 4, the two are connected and fixed together by a quick-connect locking device 52 provided on the quick connector 5. The tail end of the quick connector 5 is provided with a threaded connector 53 that cooperates with the fixing sleeve of the dental treatment machine connection pipeline, and the tail end is provided with a sealing rubber gasket 54. It is used to achieve a quick connection between the quick connector 5 and the quick connector base 4, and between the quick connector 5 and the dental treatment machine connection pipeline. The tail end of the quick connector 5 is also provided with a water inlet 55 and an air inlet 56;

[0031] The water outlet and the annular air outlet of the nozzle 2 are respectively connected to the water supply channel and the air supply channel in the machine head 1.
