Dentist mobile phone switch connector

The invention relates to a connector for connecting a dentist mobile phone and a gas pipeline and a water conduit, in particular to a dentist mobile phone switching connector capable of directly switching compressed air and liquid supply for the purpose of improving medical efficiency and convenient operation.

Dentist mobile phone refers to a hand-held device that can be installed on a dental treatment table. It is usually used by dentists. It usually includes high-speed molar mobile phones, low-speed molar mobile phones and scalers... and other compressed air-powered mobile phones, mainly through the pedals. The phone starts. At present, the dental unit is in the pipeline for supplying normal water such as tap water or purified water to the dentist. Therefore, in the course of diagnosis and treatment, if the medicine must be sprayed, the dentist must perform the medicine in stages with a syringe or other equipment. The injection process makes the treatment process inconvenient.

In order to solve this problem, the Republic of China new patent No. M470643 "Dentist Mobile Phone" patent case provides a rotation through the control valve, so that the dentist can switch the syrup or general water directly in a medical treatment process. Although the structure of the mobile phone can solve the problem that the dentist must carry out the syrup injection in stages, only the problem exists. Firstly, due to the different patents and functions of the various brands of the dentist mobile phone, the control valve is set on the dentist's mobile phone. The structure of the switching control is easy to leak in the place where the control valve is generated. In addition to the increase in the malfunction rate of the dentist's mobile phone, this switching infusion function requires a separate pedal control board, which is easy to cause inconvenience to the dentist, and therefore the willingness of the manufacturer and the dentist. low. Therefore, the structure of the patent case does not apply to other brands or works. Can be different on the dentist's phone.

The main object of the present invention is to provide a dental handpiece switch connector that can be applied to any brand and can be arbitrarily installed or removed as needed by the dentist.

A secondary object of the present invention is to provide a dentist mobile phone switching connector that avoids a leakage or malfunction of a dentist's mobile phone due to a change in structure.

To achieve the above objective, the present invention provides a dentist mobile phone switching connector, which mainly includes a connector body, an infusion control valve and an air outlet control valve, and the infusion control valve is configured to pass a liquid switching structure through a rotary infusion control valve. The output end of the infusion tube provided on the connector body is connected with the input end, or the infusion channel is connected with the output end of the infusion tube, and the output end of the infusion tube and the input end are not connected to each other, and the rotary outlet control valve is transmitted through The gas outlet control valve is also configured to connect the two ends of the gas pipe provided on the connector body by gas switching structure, or to connect the two ends of the gas pipe and the gas outlet passage.
