Technical Field

[0001] The utility model relates to the technical field of toothbrush manufacturing, in particular to an installation structure for a detachable electric toothbrush head which is convenient to disassemble. Background Art

[0002] When an electric toothbrush is used for brushing teeth, toothpaste foam may flow into the gap where the toothbrush head is connected along the toothbrush handle. At the same time, an electric toothbrush is a daily necessity for oral use. Therefore, keeping the electric toothbrush clean and fresh is beneficial to maintaining dental health.

[0003] When installing the head of an electric toothbrush, usually an installation rod is inserted into the inside of the toothbrush head. At the same time, in order to keep the toothbrush head tightly connected to the electric toothbrush, the width of the installation rod is slightly smaller than the diameter of the installation hole inside the toothbrush head. Therefore, it is more difficult to install the toothbrush head. At the same time, when installing the toothbrush head, if the toothbrush head cannot fully enter the inside of the toothbrush head, it will affect the swing of the toothbrush head, thereby affecting the cleaning effect. When the existing electric toothbrush is installed with the toothbrush head, the user cannot accurately judge the installation position of the toothbrush head, so that the electric toothbrush cannot achieve the due cleaning effect.

[0004] In view of the above situation, we propose an installation structure for a detachable electric toothbrush head which is convenient to disassemble. Content of the Utility Model
