Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

As shown in FIGS. 1-8, one embodiment of the present invention: the utility model provides a self-cleaning instrument, includes shell body 10, its characterized in that, shell body 10 has accomodates the chamber, accomodate the upper and lower both sides in chamber and seted up ring shape spout, still include:

two sets of transmission devices which are oppositely arranged, wherein each transmission device comprises a sliding block 20, a motor 21, a first gear 25, a second gear 26 and a third gear 27, the upper end and the lower end of each sliding block 20 are respectively positioned in the sliding grooves, the motors 21 are fixedly arranged on the sliding blocks 20, the first gears 25 are fixedly arranged on the shell bodies 10, the second gears 26 and the third gears 27 are coaxially arranged on the output shafts of the motors 21, the first gears 25 are meshed with the second gears 26, and the first gears 25, the second gears 26 and the sliding blocks 20 form a planetary mechanism;

the cleaning device comprises a processor, a rack 24 matched with the third gear 27, bristles 22 arranged on the rack 24, magnets 30 arranged at one end of the rack 24 and a polished rod 23 arranged at the other end of the rack 24, wherein the two magnets 30 are oppositely arranged, a limiting groove is formed in the sliding block 20, the rack 24 is positioned in the limiting groove, and the processor is in signal connection with the motor 21.

Further, the first gear 25 is disposed on the housing 10 through a fixing member 29.

Further, a water inlet 31 is opened on one side of the housing 10 facing the brush 22.

Further, the first gear 25 opens on a dashboard 28 of the self-cleaning instrument.

Further, the bristles 22 are antistatic bristles 22.

The processor is an MCU singlechip.

When in work:

referring to fig. 2 and 7, after the self-cleaning procedure is started, the two motors 21 are started, the motors 21 drive the second gear 26 and the third gear 27 to rotate through the shafts of the motors 21, and meanwhile, the first gear 25 and the instrument panel 28 are fixed, so that the slider 20, the second gear 26, the third gear 27, the motors 21, the shafts of the motors 21, the electromagnet 30, the rack 24 and the polish rod 23 can perform circular motion around the circle center, but due to the limiting effect of the slider 20, the polish rod 23, the rack 24 and the magnet 30 always point to the circle center, the third gear 27 rotates to drive the rack 24 to feed to the circle center, and meanwhile, the bristles 22 on the side surfaces of the rack 24 and the magnet 30 contact with the surface of the instrument panel 28, so as to clean the surface of the;

referring to fig. 8, after the two magnets 30 contact each other, the rack 24 just disengages from the engagement with the third gear 27, and the polish rod 23 does not contact the third gear 27, so the second gear 26 drives the slider 20, the third gear 27, the motor 21, the shaft of the motor 21, the electromagnet 30, the rack 24, and the polish rod 23 to rotate around the circumference, and the rack 24, the polish rod 23, and the magnet 30 do not feed, and after 1-2 circles of circular motion, the motor 21 rotates reversely, and because the two magnets 30 are homopolars and have repulsive force, the rack 24 is pushed away from each other, so that the rack 24 resumes the engagement with the third gear 27, and the motor 21 rotates reversely to drive the rack 24, the polish rod 23, and the magnet 30 to reset, and the self-cleaning process is finished, and in the cleaning process, the water inlet 31 may be externally connected with an injection device, and the cleaning liquid is injected to the.
