Referring to fig. 1-5, the connection relationship of the components is only schematically shown, the cleaning device is only used for explaining the working principle of the metering rod of the planetary gear mechanism, all the pipe fittings in practical application are not drawn, and the cleaning device is not in proportion to the actual product. The arrows in fig. 3 and 4 indicate the direction of rotation of the sun wheel 10, the planet wheels 11, the brush roller 15 and the metering rod 22, and the arrow in fig. 5 indicates the direction of insertion of the metering rod 22 when it is mounted.
The cleaning device comprises a packaging shell 1 arranged on a frame 23, and a cabin door 2, a water inlet 3, a water outlet 4, an overflow outlet 5, a threaded pin 6 and a bearing assembly 7 which are arranged on the packaging shell. Inside the package housing 1, a plurality of stages of fixed planetary gear mechanisms 8 are provided (the number of the fixed planetary gear mechanisms 8 is not particularly limited here, and generally, the longer the length of the metering rod 22, the larger the number of the mechanisms). The fixed planetary gear mechanism 8 consists of an internal gear 9, a sun gear 10, a planetary gear 11 and a planetary gear retainer 12, and the planetary gear retainer 12 in the fixed planetary gear mechanism 8 is sleeved on the metering rod 22 in an empty mode and plays a supporting role for the metering rod 22. A movable planetary gear mechanism 13 is arranged at one end of the interior of the packaging shell 1 close to the cabin door 2, the basic structure and the function of the movable planetary gear mechanism are the same as those of the fixed planetary gear mechanism 8, a locking nut 14 is further arranged on the planetary gear 11 of the movable planetary gear mechanism 13, a metering rod 22 can be locked with the planetary gear 11 of the mechanism, and the metering rod 22 synchronously moves and rotates axially and synchronously with the planetary gear 11 of the mechanism. The planet wheel 11 and the planet wheel holder 12 in the movable planet gear mechanism 13 can axially move in a certain range, and a brush roller 15 provided with a brush 24 is also arranged in the packaging shell 1, is arranged on the transmission shaft 21 and rotates along with the transmission shaft. It is ensured that all the furrows (teeth) on the surface of the metering rod 22 are in contact with the bristles 24 of the brush roller 15, so that all the furrows (teeth) on the surface of the metering rod 22 are cleaned.
The spiral reciprocating mechanism consists of a spring 16, a rear pressure plate 17, a hand wheel 18, a screw rod 19 and a front pressure plate 20, and can push the planet wheel 11 and the planet wheel retainer 12 in the movable planet gear mechanism 13 to reciprocate and drive the metering rod 22 to do reciprocating linear motion.
As shown in FIG. 1, there is a space between the brush roller 15 and the metering rod 22, and the metering rod 22 can clean the furrows (teeth) when the brush roller 15 rotates. The bearing assembly 7 supports the rotation of the transmission shaft 21.

During operation, the linear velocity of brush roller 15 is higher than the linear velocity of metering rod 22, so that the difference in velocity between metering rod 22 and brush 24 forms friction, and cleaning of metering rod 22 is achieved. The grooves (teeth) of the metering rod 22 can be contacted with the brush 24 and the cleaning liquid, and the brush 24 brushes in the direction of the grooves (teeth) of the metering rod 22 for a certain period of time (here, the specific cleaning time is not limited, and generally, the less clean the metering rod 22 is, the longer the cleaning time is). The self-rotation of the metering rod 22 can clean the circumference of the metering rod 22, the axial displacement cleaning can be carried out by using a spiral reciprocating mechanism at the position which is not contacted with the hairbrush 24 in the axial direction of the metering rod 22, and overflow water during cleaning is discharged through the overflow discharge port 5. After a period of cleaning, the metering rod 22 is axially and basically cleaned, only the part which is not in contact with the brush 24 is not cleaned, at this time, the hand wheel 18 on the cabin door 2 can be rotated, the screw rod 19 connected with the hand wheel 18 generates spiral reciprocating motion, and then the movable planetary gear mechanism 13 is pushed to axially move, the metering rod 22 is driven to generate displacement, so that the part which is not in contact with the brush 24 originally is in contact with the brush 24, and the cleaning is achieved. After the cleaning is finished, the hand wheel 18 is rotated reversely, so that the metering rod 22 can reset, and after the cleaning is finished, the water outlet 4 is opened to discharge dirty liquid. The power source for rotating the transmission shaft 21 is not within the scope of the present invention, and therefore is not shown in the drawings.
The invention is claimed in the structure of the cleaning device for the metering rod of the planetary gear mechanism, and although cleaning liquid, water and the like are used in practical use, the cleaning liquid and the water are not within the protection scope of the invention. It should be noted that, all the ways of using the planetary gear mechanism to drive the metering rod and the brush roller to clean do not change the essence of the technical scheme, and all the ways belong to the protection scope of the present invention.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the technical spirit of the present invention should be covered within the protection scope of the present invention.
