Abstract

FIELD OF THE INVENTION The invention relates to sanitary and hygienic accessories, namely toothbrushes. The purpose of the invention is to improve the performance by increasing the brush exposure sector. In the toothbrush, the head is made in the form of a glass and installed on the rod with the possibility of reciprocating and rotational movements. The rod is provided with a fixed finger, which is located in the through guide groove made in the body of the glass. The groove in turn is made inclined to the axis of the glass. The groove may also have a V-shape. 7 il.

Description

This invention relates to sanitary articles, namely toothbrushes,

The purpose of the invention is to improve ease of use and expansion of technological capabilities.

FIG. 1 shows a toothbrush, a general view; in fig. 2 - the same, with a block displaced relative to the handle; FIG. 3 is a section A-A in FIG. one; in fig. 4 is a view B in FIG. one; in fig. 5 shows a section B-B in FIG. 2; in fig. 6 is a view of FIG. 2; in fig. 7 is a guide groove, an embodiment.

The toothbrush (fig. 1 and 2) consists of the handle 1, connected by means of the transition neck 2 to the rod 3. On the rod 3 there is a head made in the form of a cup 4, on a part of whose spherical surface the pile 5 is placed. the pin 3 is fixedly mounted with a finger 6, which is simultaneously located in the through-through guide pzzu 7, which is inclined to the axis of the sleeve 4 in the body of the latter (Fig. 4 and 6). The glass 4 is installed on the rod 3 with the possibility of reciprocating and rotational movements

The guide groove 7 may be V-shaped.

The toothbrush is used as follows.

Holding the handle, the toothbrush is inserted with the pile head into the oral cavity and moves along the rows of teeth. In this case, the tumbler cup 4 with pile 5, when the toothbrush moves forward with the pile head (Fig. 1), remains stationary relative to the rod 3 (Figs. 3 and 4). When the toothbrush moves in the opposite direction, the tumbler 4 with pile 5 (Fig. 2) moves further linearly with respect to rod 3, turning at a certain angle relative to the axis of symmetry of pile 5, determined by the amount of stroke of the finger 6 in an inclined direction the groove 7 (Fig. 5 and 6). When the direction of movement of the toothbrush in the cavity of the mouth is changed, the tumbler 4 with the pile 5 returns to its original position, completing the translational and

rotational motion relative to the rod 3

Thus, when cleaning teeth, glass 4 with pile 5 performs complex movements relative to the surface of the teeth (linear movement along rows of teeth with simultaneous reciprocating and rotational movements relative to the rod 3), thereby providing high-quality cleaning as the very surface of the teeth, and the joints between the latter.

When using a toothbrush in which the guide groove 7 is made V-shaped, the quality of cleaning the tooth surface is improved due to the possibility of rotating the glass A with the pile 5 to both sides of the axis of symmetry of the pile 5 (Figs. 3, 5 and 7).

The proposed toothbrush, in comparison with the known one, provides an increase in ease of use and broadens the technological capabilities by increasing the sector of action of the brush, which contributes to a better cleaning of the tooth surface, as well as joints between the latter.

Claims (1)
