The shaft of the electric motor 2 is indispensably npt- of the sleeve 12 is connected with the shaft 13, the other end of which, with the help of the sleeve with the groove 14, is connectable to the bristle head 15

The bristle head 15 has a protective case 16 with an additional to analogue i 17 for supplying toothpaste the head and the fu (the lid is not detachably connected and the replaceable nozzle is presented together. The latter is connected to the body 1 by means of a lock containing case 18 with the housing 1. mounted in the housing on the guides 19 and 20, the latch 21 and the hook 22 fixed to the housing of the nozzle, which is placed between the guides 19 and 20 and the curved end of the 23 - latch slot 21

For storage and supply to the bristle head 15 of the toothpaste in the housing 1, parallel to the intermediate shaft, a collector 24 with a rectangular cross section is installed, which has a nipple 25 covered with a plug 26. A projection 27 is provided on which a protective case of 16 replacement nozzle with channel 28 for feeding pasta. For supplying the toothpaste to the bristle head 15 of the toothpaste in the collector 24 there is a spindle 29 on which the piston 30 of rectangular section is placed in the nuts with the handle 31.

The electromechanical toothbrush is used as follows.

The replaceable nozzle is mounted on the protrusion 27 so that the end of the bristle head 15 is aligned with the groove of the sleeve 14, the rod 22 passes between the guides 20 and 19. And the end 23 enters the casing 18 of the lock and passes through the groove located on the latch 21 , upers to the back wall of the casing. After that, the latch 21 is moved to the stop, the groove on it is shifted to the side, locking the end 23.

To fill the collector 24 with toothpaste, the piston 30 is moved to the rearmost position by rotating the lead screw 29, the plug 26 is unscrewed, the neck of the tube of toothpaste is pressed against the tapered bore of the socket 25 and the toothpaste is squeezed into the collector 24.

To feed the toothpaste to the bristle head 15, the spindle 29 is rotated by the handle 31, which drives the piston 30, which squeezes the toothpaste through the collection channel 28 and through the additional channel 17 to the bristle head 15.

To actuate the rotation of the bristle head 15, the head 11 of the three-position switch is transferred, depending on the direction of rotation of the bristle head 15, to one of its extreme positions. At the same time, the contacts of the electric motor are supplied with voltage from batteries 3 and 4, its shaft begins to rotate, rotating the rigidly set

there is an intermediate shaft 13 on it, which rotates the bristle head 15. When moving the head of the switch 11 to another extreme position, the voltage applied
