The capacity for wringing 15 is installed on supports 19 from the side of one of the tops of the oval horizontal section of the wall of the tank for washing liquid 14. liquid 14 is rigidly attached to the washing rack 16 with an upper end surface equipped with a spherical head 18, made with the possibility of rotation around the axis of the washing rack 16. made with the possibility of rotation around the axis of the wringing rack 17, and rigidly attached to the center of the bottom part of the container for washing liquid 14, limited by the projection of the wringing container 15 onto it.

When mounting the mop 1 on the rod 11 at a distance from its lower end, approximately equal to 0.5 of the height of the nozzle 3, the screw sleeve 5 is fixedly fixed, having a cylindrical shape with four spiral grooves 20 made on its outer cylindrical surface, located at an equal distance from each other. each other, and with a fixing disk 9 fixed in the upper part of the screw sleeve 5. The inner diameter of the screw sleeve 5 and the diameter of the rod 11 are assumed to be approximately equal to 20 mm. A toothed screw slider 6 is installed on the screw sleeve 5, having a cylindrical shape and made with four spiral grooves with rolling elements 23 located on its inner cylindrical surface at an equal distance from each other with the possibility of their free movement in the response spiral grooves 20 of the screw sleeve 5. When in the manufacture of the screw sleeve 5, its outer diameter is taken to be approximately equal to 40 mm, the height is approximately equal to 300 mm, the angle of inclination of the spiral grooves 20 relative to the axis of the rod 11 is approximately equal to 30°. In the manufacture of a screw slider 6, its inner diameter is taken to be approximately equal to 45 mm, its height is approximately equal to 50 mm, the angle of inclination of the spiral grooves with rolling elements 23 relative to the axis of the rod 11 is equal to the angle of inclination of the helical grooves 20 of the screw sleeve 5. With these parameters, for one full the course of the toothed screw slider 6 along the cylindrical surface of the screw sleeve 5 makes it possible to turn the nozzle 3 with the fringe 4 approximately 360°. Four return springs 8 are attached to the upper part of the toothed screw slider 6, placed around the circumference of the upper part of the toothed screw slider 6 at an equal distance from each other, the opposite ends of which are fixed along the circumference of the mounting disk 9 at an equal distance from each other. To the lower part of the rod 11 on the axis 12, a nozzle 3 is movably attached, equipped with a fringe 4, with a socket 22 fixed inside it, equipped with a spring ring 21 with the possibility of fixing it on the spherical heads of the washing 16 and wringing 17 racks. The handle 2 is made of a hollow shape with the possibility of placing a rod 11 in its internal cavity. A cap 10 is rigidly attached to the lower part of the handle 2. A toothed clamping sleeve 7 is fixedly attached to the lower part of the cap 10, which is made with an inner diameter that allows free movement of the toothed clamping sleeve 7 through the mounting disk 9. The size and location of the teeth on the toothed clamping sleeve 7 are made corresponding to the size and location of the teeth of the toothed screw slider 6. After placing the rod 11 in the inner cavity of the handle 2, it is equipped with a stopper 13, which limits the movement of the rod 11 in the inner cavity handles 2.

As a result of this design, a higher reliability of this device for wet cleaning floors in rooms is ensured.

When rinsing and wringing out the fringe 4, the socket 22 of the mop 1 is placed respectively on the washing 16 and wringing 17 racks of the container for washing liquid 14 and the container for wringing 15 with the fixation of the spring ring 21 on the spherical head 18. Loosen the tightening of the stopper 13 and perform a vertical reciprocating movement handle 2 on the rod 11. As a result of the downward movement of the handle 2, the cap 10, overcoming the resistance of the return springs 8, lowers the toothed clamping sleeve 7 until its teeth come into contact with the teeth of the toothed screw slider 6, while ensuring that their position is fixed relative to each other and relative to the vertical plane movements of the handle 2. Screw sleeve 5 under the influence of spiral grooves with rolling elements 23 of the toothed screw slider 6, interacting with the reciprocal spiral grooves 20 of the screw sleeve 5, drives the rod 11 in rotation and through it and the axis 12 - nozzle 3 with fringe 4. In as a result of the centrifugal silt provide effective rinsing and effective wringing of all fringe ropes 4.

When the handle 2 is lifted up, by means of the cap 10, the toothed clamping sleeve 7 is raised, disengaging its teeth from the mating teeth of the toothed screw slider 6, and the toothed screw slider 6, under the influence of the return springs 8, rises to the mounting disk 9. Subsequent actions are performed in the same sequence until the desired result is achieved by rinsing and wringing out the fringe 4 of the nozzle 3.

After the completion of the extraction of the fringe 4, the nozzles 3 tighten the stopper 13, lift the mop 1 by the handle 2 and remove the spring ring 21 of the socket 22 from the connection with the spherical head 18 of the extraction rack 17.

As a result of the use of this device, an increase in the reliability of the device for wet cleaning of floors in rooms is ensured.
