  As described in Patent Documents 1 and 2, with a manual cleaning tool configured to wipe dirt on the tooth surface with a cleaning cloth made of woven or non-woven fabric, basically the cleaning cloth is configured in a bag shape, This bag-shaped cleaning cloth is configured to be fitted on the head of the handle tip and used, and the cleaning cloth needs to be molded into a bag shape, which increases the production cost of the cleaning cloth. was there. In addition, because the cleaning cloth is configured in a bag shape, the amount of disposable material cloth used is increased. In particular, when an expensive fiber material such as ultrafine fibers is used, the production cost per cleaning cloth is reduced. There was a problem of becoming higher. Furthermore, although many tooth surface cleaning tools for manual wiping operation have been filed, no electric tooth surface cleaning tool has been proposed or implemented.

  The objective of this invention is providing the electrically driven tooth surface cleaning tool which attached the cleaning cloth for cleaning a tooth surface.

  A tooth surface cleaning tool according to the present invention includes a cleaning cloth for cleaning a tooth surface, a cleaning head to which the cleaning cloth is detachably attached, and an electric drive means for cleaning the cleaning head. It is.

  In this tooth surface cleaning tool, the cleaning cloth is attached to the cleaning head, the cleaning cloth is applied to the tooth surface while the cleaning cloth is moved together with the cleaning head by the driving means, and the tooth surface is sequentially cleaned. Since the tooth surface can be cleaned by electrically cleaning the cleaning cloth in this way, it is possible to clean the tooth surface by properly cleaning the tooth surface regardless of gender and age. It is possible to effectively prevent poor cleaning due to operational variations.

  Here, in the preferred embodiment, the driving means is an electric driving means, and the cleaning movement of the cleaning head by the driving means is any one of rotational movement, reverse reciprocating movement, reciprocating linear movement, and vibration. . Such a cleaning movement can be realized by attaching a replacement cleaning tool having a cleaning head of a cleaning cloth at the tip of the existing electric toothbrush having an electric drive means instead of the replacement brush. The reciprocating reciprocating motion means a motion that repeats a rotating motion of rotating by a constant angle in the forward rotation direction and then rotating by the same angle in the reverse rotation direction.

  It is preferable that the cleaning of the tooth surface with the cleaning cloth includes at least one of wiping off the dirt on the tooth surface, polishing the tooth surface, polishing the tooth surface, and waxing the tooth surface. The cleaning movement when wiping off the dirt on the tooth surface is a movement to wipe off the dirt on the tooth surface with a cleaning cloth, an action for adsorbing the dirt on the tooth face onto the cleaning cloth, and removing the dirt on the tooth face with a cleaning cloth. Includes exercise.

  As the cleaning cloth, it is preferable to use one made of ultrafine fibers. A cleaning cloth made of such ultrafine fibers is expensive, but is preferable because it can cleanly remove dirt adhering to fine irregularities on the tooth surface.

  The cleaning head has a pressing part that presses the cleaning cloth against the tooth surface, and a holding part that holds the outer peripheral part of the cleaning cloth so that the cleaning cloth is stretched along the surface of the pressing part. It is a preferred embodiment to use. By providing the pressing portion and the holding portion on the cleaning head in this manner, the cleaning cloth can be reliably fixed to the cleaning head. In particular, when a single flat cleaning cloth is used as the cleaning cloth, the processing can be easily performed as compared with the case of processing into a bag shape, and the amount of the material cloth used can be reduced.

  It is also a preferred embodiment that at least a portion of the pressing portion where the cleaning cloth is stretched is made of a soft member. If comprised in this way, since the pressing part which contact | abuts a tooth surface on both sides of a cleaning cloth will be comprised with a soft member, soft contact with respect to a tooth surface can be implement | achieved, and a cleaning cloth should be inserted by any chance. Even when the pressing part hits the gingiva or the like, the gingiva can be prevented from being damaged.

  An accommodating portion that accommodates an outer edge portion of the cleaning cloth may be formed in the cleaning head. By comprising in this way, it can prevent that the outer edge part of a cleaning cloth exposes outside, and can improve the appearance in the state which attached the cleaning cloth with respect to the cleaning head.

  As the cleaning head, one having a cleaning head main body having a pressing portion and a holding ring that is externally fitted to the base portion of the pressing portion and holds the outer edge portion of the cleaning cloth can be used. Although it is possible to provide the holding part and the pressing part in one member, the holding structure of the cleaning cloth by the holding part becomes complicated, so it is preferable to provide the holding part and the pressing part in separate members.

  As the cleaning head, a single member having a pressing portion and a holding portion may be used, and the outer edge portion of the cleaning cloth may be inserted and held in the holding portion. In this case, the manufacturing cost can be reduced by reducing the number of parts constituting the cleaning head.

  As the cleaning head, a single member having a pressing part and a holding part is used, and the cleaning cloth is insert-molded with respect to the cleaning head so that the outer edge of the cleaning cloth is embedded and held in the holding part. Is also a preferred embodiment. Thus, when insert-molding the cleaning cloth with respect to the cleaning head, the disposable cleaning head can be easily mass-produced. Moreover, since the attachment precision and attachment intensity | strength of a cleaning cloth can be improved compared with the case where a cleaning cloth is assembled | attached mechanically with respect to a cleaning head, it is preferable.

  In another preferred embodiment, the cleaning head includes a movable body that performs a cleaning movement by the driving unit, and a head member that is detachably attached to the movable body and includes a pressing portion and a holding portion. If comprised in this way, it becomes possible to comprise only a head member disposable, and since the part made disposable can be decreased as much as possible, it is preferable.

  Since the electric toothbrush according to the present invention can electrically clean the cleaning cloth and clean the tooth surface, regardless of gender and age, the cleaning surface of the tooth can be cleaned by appropriately cleaning the cloth. Therefore, it is possible to effectively prevent poor cleaning due to variations in the cleaning operation by the user.
