[0029] Figures 4 to 5 A second embodiment is shown, which differs from the first embodiment mainly in that:

[0030] The cleaning component includes a first motor 9 fixed to one side of the cleaning robot body 1, the first motor 9 is a reduction motor, the first rotating shaft 4 passes through the cleaning robot body 1 and is fixed to the output end of the first motor 9, a cleaning box 10 is installed on the inner wall of the cleaning robot body 1, a partition 11 is fixed on the inner wall of the cleaning box 10, the partition 11 divides the cleaning box 10 into a urine storage bin 13 and a water storage bin 12, and a drain component for draining the water from the water suction roller 7 is installed on the end of the cleaning box 10 away from the water suction roller 7.

[0032] An upper inclined surface 18 and a lower inclined surface 19 are formed on one end of the water squeezing block 16 away from the spring 17 , and a supporting positioning block 20 is fixed on one side of the cleaning robot body 1 close to the water suction roller 7 .

[0033] This application provides a cleaning component so that the suction roller 7 for absorbing urine can be cleaned in time, thereby ensuring the effect of the suction roller 7 on cleaning urine when the suction roller 7 is used next time, thereby improving customer experience.

[0034] Working principle:

[0035] The cleaning robot body 1 adopts the pet excrement cleaning robot in CN 217564482 U, which is the prior art and will not be described in detail.

[0036] When a pet defecates within the cleaning range of the cleaning robot body 1, the smell of the excrement will be received by the gas sensor 3. When the gas sensor 3 recognizes it as pet excrement, the cleaning robot body 1 is started to move. The gas sensor 3 locates the excrement according to the concentration of gas molecules, and moves the cleaning robot body 1 to the excrement to clean it.

[0037] When the excrement is identified as urine, the cleaning robot body 1 moves the water-absorbing roller 7 to the top of the urine, starts the second motor 8 to make the second rotating shaft 6 drive the water-absorbing roller 7 to rotate and roll to absorb the urine. When the urine is absorbed, the first motor 9 starts to drive the first rotating shaft 4 to rotate, so that the rotating rod 5 drives the water-absorbing roller 7 to turn over. When the water-absorbing roller 7 contacts the upper inclined surface 18 of the squeezing block 16, the urine squeezed out of the water-absorbing roller 7 by the squeezing block 16, the second motor 8 drives the water-absorbing roller 7 to rotate again so that the water-absorbing roller 7 evenly discharges the urine through the squeezing block 16, and the urine flows into the urine storage bin 13 along the water guide plate 14.

[0038] When urine is discharged, the first motor 9 continues to rotate the water-absorbing roller 7 downward, squeezing the upper inclined surface 18 of the squeezing block 16 to compress the spring 17, and the squeezing block 16 then slides in the slide hole to the side away from the water-absorbing roller 7 to avoid it, until the water-absorbing roller 7 resists the gravity of the counterweight block 15 to press the water guide plate 14 to the side of the water storage bin 12, and the spring 17 also rebounds. At this time, the second motor 8 is driven to rotate the water-absorbing roller 7 in the water storage bin 12 for cleaning;

[0039] After cleaning is completed, the first motor 9 causes the water-absorbing roller 7 to reverse until the water-absorbing roller 7 contacts the lower inclined surface 19 of the squeezing block 16, and the second motor 8 is started to rotate the water-absorbing roller 7 to squeeze out the water, and then the water-absorbing roller 7 continues to reverse, and the squeezing block 16 is also squeezed and avoids it until the rotating rod 5 contacts the supporting positioning block 20, and then it can prepare for the next urine cleaning work.
