Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

As shown in Figures 1 to 4, an electric interdental polishing cone of the present invention includes a brush rod 1, a locking sleeve 2, a polishing cone 3, a transmission shaft 5, a guide sleeve 6, a fixing sleeve 7 and a spring 8; The transmission shaft 5 is cooperating with the guide sleeve 6 and installed in the inner cavity of the brush rod 1; one end of the transmission shaft 5 passes through the fixed sleeve 7 so that the fixed sleeve 7 can move up and down; the The fixing sleeve 7 is installed inside the brush rod 1; the spring 8 is installed between the locking sleeve 2 and the fixing sleeve 7, the upper end is in contact with the locking sleeve 2, and the lower end is connected with the fixing sleeve. 7 phase top; the polishing cone 3 is replaceably installed on the fixed sleeve 7; the locking sleeve 2 is buckled in the fixed sleeve 7 so that it can move up and down.

The electric interdental polishing cone also includes a connecting sleeve 4 installed on the other end of the transmission shaft 5 . The electric interdental polishing cone also includes a sealing ring 9 installed on the outer ring of the brush rod 1 . The spring 8 is pagoda-shaped and easy to install. The brush holder 1 is made of plastic.

When the locking sleeve 2 is pressed down, the spring 8 is compressed, and the polishing cone 3 can be taken out for replacement. When the locking sleeve 2 recovers, the spring 8 recovers, and the polishing cone 3 is locked and cannot move. During work, the brush rod 1 is connected with the motor part of a general-purpose electric toothbrush, inserted into the connecting sleeve 4, and drives the transmission shaft 5 to rotate, so that the polishing cone 3 moves up and down, which is conducive to better polishing between the teeth.

The electric interdental polishing cone of the utility model has a simple structure and is beneficial to better polishing between the teeth; moreover, the polishing awl is convenient to replace.

To sum up, the above-mentioned embodiment is not a limiting embodiment of the present utility model, and all modifications or equivalent deformations made by those skilled in the art on the basis of the essential content of the present utility model are included in the scope of the present utility model. technology category.
