Kind Code:
A1
Abstract:
An electric toothbrush head (10) and an electric toothbrush. The electric toothbrush head (10) comprises a toothbrush head housing (100), a bristle member (200), and a counterweight member (300). In an extension direction of the toothbrush head housing (100), the toothbrush head housing (100) comprises a bristle end (110) and a connecting end (120) opposite to each other, the connecting end (120) being used for being connected to a transmission shaft (21) of a toothbrush handle of the electric toothbrush; an accommodating cavity (101) is formed inside the toothbrush head housing (100), and the position where the accommodating cavity (101) is formed is close to the bristle end (110); the bristle member (200) is provided at the bristle end (110); the counterweight member (300) is detachably provided in the accommodating cavity (101), and when the counterweight member (300) is located in the accommodating cavity (101), the counterweight member (300) is close to the bristle end. According to the electric toothbrush head (10) and the electric toothbrush, the counterweight member (300) is provided in the accommodating cavity (101) formed inside the toothbrush head housing (100), i.e., the swing of the toothbrush head housing (100) is counterweighted, so that the vibration of the toothbrush handle connected to the toothbrush head housing (100) can be effectively reduced and noise can be ensured to be as low as possible; moreover, the counterweight member (300) is disposed close to the bristle end (110), i.e., the counterweight member (300) is disposed away from the connecting end (120), such that a driving effect of the transmission shaft 21 on the toothbrush head housing 100 is not affected.
