Interdental brush

An interdental brush device, comprising:

• an interdental brush comprising a working part and a connector;
• a delivery component comprising:
• a guide head disposed on a front end of the delivery component and comprising a bended tube, wherein an outlet of the bended tube is disposed at an end of the guide head,
• a sliding mechanism comprising a sliding block and an interdental brush connecting mechanism, wherein the interdental brush connecting mechanism is disposed on a first end of the sliding block,
• a housing, and
• a driving spring adapted to push the sliding mechanism to slide on the guide head, wherein one end of the driving spring is connected to a second end of the sliding block and an opposite end of the driving spring is connected to the housing;
• and
• a camera system configured to enable observation of a working state of the interdental brush and oral cavities of a user during cleaning, the camera system comprising:
• a camera system housing mounted on the bended tube of the guide head at the front end of the delivery component,
• a camera affixed to the camera system housing, wherein the camera is positioned such that the field of view of the camera is directed in a same direction as the interdental brush while the interdental brush is extended from the outlet in the working state;
• a data processing and outputting system;
• and
• an electrical system disposed within the delivery component;
• wherein the interdental brush is movably disposed within the bended tube of the front end of the delivery component;
• wherein the interdental brush is positioned within the bended tube, and the connector of the interdental brush is detachably coupled to the interdental brush connecting mechanism of the sliding mechanism such that lateral movement of the sliding mechanism along the guide head drives the working part of the interdental brush to slide within the bended tube;
• and
• wherein the sliding mechanism is configured to make the working part of the interdental brush extend from the outlet of the bended tube at the end of the guide head.
