Description

Technical Field

[0001] The utility model relates to the technical field of electric toothbrushes, in particular to a quick-detachable electric toothbrush head. Background Art

[0002] An electric toothbrush uses the rapid rotation or vibration of the electric motor to generate high-frequency vibrations in the brush head, instantly breaking down the toothpaste into fine foam and deeply cleaning the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the oral cavity and have a massage effect on the gum tissue. The main structure of an electric toothbrush generally includes a brush head and a handle. A drive structure is provided in the handle, and the brush head and the handle are detachably connected, which makes it convenient to replace a new brush head. When the brush head is installed in the handle, the drive structure in the handle drives the brush head to move. However, the existing installation structure between the brush head and the handle is relatively cumbersome, and the operation is relatively cumbersome and inconvenient when replacing a new toothbrush head.

[0003] In view of the above problems, the present utility model is proposed. Utility Model Content

[0014] Preferably, the height positions of the two card slots are consistent, and the side of the pressing plate away from the bracket is flat.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The first plug plate and the second plug plate move upward in contact with the inner wall of the brush head. When the first clamp head and the second clamp head enter the two clamping grooves respectively, the brush head and the handle are installed. The first plug plate and the second plug plate move up and down to drive the entire brush head to reciprocate, thereby realizing the brushing function.

[0017] When the brush head needs to be removed and replaced with a new one, the thumb and index finger respectively press the buttons on both sides to move the top plates on both sides toward the slots. The top plates can pass through the slots to push out the first clamp head and the second clamp head respectively, so that the first clamp head and the second clamp head leave the slots. In this way, the handle, the first plug plate and the second plug plate can be pulled down together to achieve the removal of the brush head. The removal operation of the brush head is relatively convenient and quick, and can achieve quick disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS
