Description

Movable multi-function toothbrush

The present invention relates to a toothbrush, and more particularly to a mobile multifunctional toothbrush.

The Bass method of brushing is a method that most medical scholars and experts consider to be more accurate and efficient in brushing. The definition of brushing is shown in Figure 1:

Use two toothbrushes as the unit to move up and down with the toothbrush (for the upper row of teeth to move from top to bottom and vice versa, for the lower row of teeth to move back and forth in a bottom-up manner), move up and down and clean After several times, move to other teeth in sequence to repeat the cleaning.

In general, when using the Bayesian brushing method, it is necessary to control the toothbrush to move up and down as much as possible at an angle of forty-five degrees, and it is necessary to control the force of the toothbrush so that the bristles of the toothbrush are half against the gums against the teeth. Therefore, in order to correctly perform the Bayesian brushing method to completely clean the teeth, it is not very convenient for the average user to control the speed and strength of the toothbrush, and often causes the brushing time to be too long, which causes the wrist of the toothbrush to be tired. Feeling is not quite convenient.

Therefore, there is now a Multiway toothbrush that has been proposed to improve the shortcomings of conventional toothbrushes. Referring to Figure 2, the brush head of the multi-function toothbrush is designed as a T-shape. This design allows the user to easily perform the movement of the toothbrush up and down, while the brush head is perpendicular to the toothbrush handle. Features, can clean more than two teeth at a time, thus greatly reducing the brushing time. However, when such a multiplexed toothbrush is used for cleaning incisors or canine teeth, since the handle of the toothbrush is kept vertical, it is convenient compared to the use of a conventional toothbrush, but the disadvantage is that when the teeth on the inner side of the cheek are to be cleaned (for example, large Caries or small molars), because the multiplexed toothbrush handle cannot maintain the same vertical direction as the incisors or canines (as shown in Figure 3), the wrist must be turned to allow the multiplexed toothbrush to be cleaned in the deep mouth, thus instead It is more inconvenient for the user, especially when cleaning the back of the teeth.

Therefore, whether using traditional toothbrushes or multiplexed toothbrushes, when performing the Bayesian brushing method to completely clean the teeth, it will cause various degrees of trouble to the user. Therefore, it is easy to make the teeth incompletely clean and cause tooth diseases. Therefore, it is necessary to improve the toothbrush seen in the market today, so that the user can easily perform the Bayesian brushing method to completely clean the teeth.

Accordingly, it is an object of the present invention to provide a movable multi-function toothbrush comprising: a handle having an aperture; a brush head coupled to the handle; and a snap-fit unit movably disposed in the handle; The snap-on unit switches between a fixed state and an active state. When the snap-in unit is switched to the fixed state, the corresponding position of the handle and the brush head is fixed, and when the snap-in unit is switched to the active state, The corresponding position of the handle and the brush head is not fixed.

Therefore, the effect of the invention is that the handle and the corresponding position of the brush head can be selectively rotated or moved, so that when a user uses the invention to clean the teeth, the toothbrush of the prior art can be effectively cleaned and is not easily cleaned. At the office.
