Technical Field

[0001] The invention belongs to the technical field of dental medical instruments, and in particular relates to an automated production device for a disposable dental three-purpose spray gun head. Background Art

[0002] The disposable three-purpose spray gun head is used with the three-purpose spray gun and is widely used as a dental equipment consumable. It uses high-pressure gas flow to spray the liquid in the nozzle for cleaning and treating teeth, gums and oral problems. It can achieve three functions: jet, liquid and spray. As a disposable three-purpose spray gun head, the existing assembly is completed by workers with some simple tooling, with a low degree of automation, low production efficiency, high dependence on workers, and human factors have a great impact on product quality.

[0003] In industrial production, most production processes of disposable three-purpose spray gun heads are completed by workers with the help of some simple tools. The production capacity is low, the degree of automation is low, the dependence on workers is high, and the human factor has a great impact on product quality. In order to improve production efficiency and product quality, an automated production equipment for disposable three-purpose spray gun heads has been developed.

[0004] The utility model with announcement number CN215080042U discloses an adapter and a dental three-purpose spray gun head. The key points of its technical solution include an adapter and a nozzle, wherein the adapter includes a detachably connected spray gun connector and a nozzle connector, and adopts a split detachable structure to achieve the connection between the nozzle and the spray gun rod. By replacing different spray gun connectors of the adapter, the nozzle can be matched with different spray guns without the need to equip multiple spray gun heads. However, its production line is not involved.

[0005] The utility model with announcement number CN221013545U discloses a three-purpose spray gun head quick disassembly structure. The key points of its technical solution include, from top to bottom, a spray gun head, a spray gun tube, a quick disassembly mechanism and a connecting pipe. The spray gun head and the spray gun tube are connected. The spray gun tube is quickly disassembled and connected with the connecting pipe through the quick disassembly mechanism. The connecting pipe can be sealed when disassembled. When the dental three-purpose spray gun is pulled out from the air pipe, no leakage will occur. It does not involve the production process.
