Referring to the drawings, it can be seen that the depth of the point A in the guide groove 37e is formed relatively deeper than the depth of the point B. Therefore, when the lifting cylinder 37a is moved in the direction of the arrow s, the transmission rod 41 is pushed by the bottom surface of the guide groove 37e to move linearly in the direction of the arrow e. In addition, the A point is formed relatively deeper than the depth of the C point.

FIG. 7 is a cross-sectional view showing the structure and operation mechanism of the stopper device shown in FIG.

As shown in the figure, a stopper mounting hole 39e is provided below the end of the push rod 33, and a stopper device 39 is provided inside the stopper mounting hole 39e. It goes without saying that the stopper mounting hole 39e communicates with the rod passage 45.

The stopper device 39 includes a leaf spring 39a having a tooth support portion 39b thereon, and a reinforcement spring 39c for upwardly elastically supporting the tooth support portion 39b of the leaf spring 39a. It is configured by.

In addition, the leaf spring 39a is provided with an inclined surface 39d which is spaced apart from the teeth 33a by the tooth support portion 39b by being pushed down by the transmission rod 41 moving in the direction of the arrow e and downwardly rotating in the direction of the arrow p. . When the tooth support portion 39b is spaced apart from the tooth 33a, the push rod 33 moves in the direction of arrow a by the elastic pressing force of the spring (35 in FIG. 1) and squeezes the toothpaste.

The inclined surface 39d is usually elastically supported upwardly so that the tooth support portion 39b is sandwiched between the teeth 33a so as to block the movement of the push rod 33 in the direction of arrow a.

In order to use the toothpaste-type toothbrush 11 of the present invention configured as described above, first, the toothpaste cartridge 43 is stored in the mounting space 15. At this time, of course, the toothpaste must be supplied inside the toothpaste cartridge 43.

If the mounting of the toothpaste cartridge 43 is completed, press the toothpaste supply switch 37 as shown in FIG. When the toothpaste supply switch 37 is pressed and released once, the electric rod 41 reciprocates once, during which the tooth support portion 39b descends from the tooth 33a and then rises again to stop the movement of the tooth 33a. .
