Definitions

  • the present invention relates to an electric toothbrush, and more particularly to an electric toothbrush head device. Background technique:
  • the current electric toothbrush is composed of a motor, a rotating shaft, a toothbrush head, a tooth holder and the like.
  • the lower end of the toothbrush head is provided with a hollow sleeve, which is directly sleeved and then rotated to the front end of the shaft, and is rotated and vibrated by the rotating shaft to drive the front end of the toothbrush to vibrate and sway.
  • the purpose of automatic tooth cleaning is achieved, but such a socket has the following defects: the hollow sleeve at the lower end of the brush head is made of a hard plastic material, the shaft is made of a metal material, and the hollow sleeve and the shaft at the lower end of the brush head are rigid. Connection, long-term use will gradually wear the inner wall of the hollow sleeve, so that the socket of the toothbrush head and the rotating shaft is loose, thus affecting the comfort and service life of the brush head.
  • An object of the present invention is to overcome the above-mentioned deficiencies of the prior art and to improve the above-described toothbrush head to provide an electric toothbrush head device which is resistant to wear and has a long service life.
  • an electric toothbrush head device comprising a rotating shaft and a toothbrush head, wherein a brush plug is arranged between the rotating shaft and the brush head, the brush head
  • the longitudinal section of the plug is substantially irregularly conical, and the brush head plug is provided with an inner cavity corresponding to the shape of the upper end of the rotating shaft, and the upper end of the inner cavity wall is provided with a flat position of the inner cavity for preventing noise from being shaken left and right by the brush head, and the inner cavity
  • the upper end of the rotating shaft corresponding to the flat position of the cavity is provided with a flat position of the rotating shaft, and the flat position of the inner cavity is closely engaged with the flat position of the rotating shaft, and the lower end of the inner wall of the inner cavity is provided with a first buckle flange protruding toward an inner portion, wherein a first retaining groove recessed inwardly on a circumferential surface of the rotating shaft corresponding to the first buckle flange, the first buckle
  • the brush plug is made of a wear resistant material, which can reduce the friction and wear caused by the vibration of the hard metal shaft and the hard plastic material.
  • the invention has the advantages that by providing a wear-resistant brush plug between the metal rotating shaft and the hard plastic toothbrush head, the long-standing wear of the electric toothbrush is solved, and the toothbrush head is connected with the upper end of the rotating shaft.

Le collier de tête de brosse (3) comprend une cavité interne (30) dont la forme correspond à celle de l'extrémité supérieure de la tige (1). L'extrémité supérieure de la paroi définissant la cavité interne (30) présente une position excentrique (31) de la cavité interne. L'extrémité supérieure de la tige (1) présente une position excentrique (11) de la tige correspondant à la position excentrique (31) de la cavité interne. La position excentrique (31) de la cavité interne est étroitement accouplée à la position excentrique (11) de la tige. L'extrémité inférieure de la paroi définissant la cavité interne (30) est pourvue d'une première bride d'attache (32) qui fait saillie vers l'intérieur. Une première rainure d'attache (12) se trouve sur la surface périphérique de la tige (1). La première rainure d'attache (12) correspond à la première bride d'attache (32) et présente une dépression orientée vers l'intérieur.
