When actually in use, water source is poured into the water storage bucket 1, and through the setting Sensor 193, when the mouse comes to the water storage bucket 1, the sensor 193 makes the shaft 14 rotate, the shaft 14 drives the half-gear 13 to rotate, the half-gear 13 drives the gear 12 to rotate, so that the gear 12 drives the rotating rod 11 and the connecting turntable 15 to rotate, when the connecting turntable 15 rotates to a certain angle, the first water outlet 16 and the second water outlet 17 overlap, so that the water source in the water storage bucket 1 enters the water collection frame 18 and falls into the placement frame 191 through the water pipe 19. When the half-gear 13 rotates When it reaches a certain angle, the teeth on the half-gear 13 and the gear 12 are disengaged, causing the gear 12 to stop rotating, driving the connecting turntable 15 to stop rotating. At this time, the first water outlet 16 and the second water outlet 17 are in a staggered state, thereby preventing the water in the water storage barrel 1 from entering the water collecting frame 18. The number of revolutions of the half-gear 13 is set according to the amount of water the mouse needs to drink, so that when the mouse comes in front of the water storage barrel 1, water can be automatically discharged, avoiding the need for manual addition, and at the same time, the amount of water discharged can be controlled to avoid wasting water resources.

[0021] A movable rod 2 is rotatably passed through the middle of the placement frame 191, and a symmetrically distributed scraper 21 is fixedly installed on the top of the movable rod 2. The scraper 21 contacts the inner wall and the lower surface of the inner wall of the placement frame 191. A matching pin 22 is provided on the side of the lower surface of the inner wall of the placement frame 191 close to the water pipe 19.

[0022] By adopting the above technical solution, the movable rod 2 is driven to rotate, which drives the scraper 21 to rotate, so that the scraper 21 scrapes off the water stains on the inner wall and the lower surface of the inner wall of the placement frame 191, and then pure water is poured to clean the placement frame 191 to prevent the water stains from contaminating the placement frame 191. The cleaned waste water is discharged by removing the pin 22 from the placement frame 191.

[0023] The bottoms of the two scrapers 21 are both provided with hollow grooves 3 .

[0024] By adopting the above technical solution and providing the empty groove 3, the water source is prevented from being blocked by the scraper 21, so that the water source can flow into the entire placement frame 191, making it convenient for the mice to drink water.

[0025] The bottom end of the placement frame 191 is fixedly mounted with support rods 4 distributed in a ring, and the number of the support rods 4 is six.

[0026] By adopting the above technical solution and providing the support rod 4, the placement frame 191 can be supported to improve its stability.

[0027] A first motor 5 is coaxially fixedly installed on the top of the rotating shaft 14 , and the sensor 193 and the first motor 5 are electrically connected. A second motor 51 is fixedly installed on the bottom end of the placement frame 191 , and the output end of the second motor 51 is coaxially fixedly installed with the movable rod 2 .

[0028] By adopting the above technical solution, by setting the first motor 5, it is convenient to drive the rotating shaft 14 to rotate through the sensor 193, and by setting the second motor 51, it is convenient to drive the movable rod 2 to rotate, so that the water stains can be scraped off.

[0029] A baffle plate 6 is fixedly installed inside the water collecting frame 18 . The baffle plate 6 is distributed in an inclined state, and the water pipe 19 is fixedly passed through the baffle plate 6 .

[0030] By adopting the above technical solution and providing the blocking plate 6 , it is convenient for water to enter the water pipe 19 .

[0031] A water inlet pipe 7 is fixedly passed through the top of the water storage barrel 1 on one side away from the half-gear 13 .

[0032] By adopting the above technical solution and providing a water inlet pipe 7 , the water in the water storage barrel 1 can be replenished through the water inlet pipe 7 after the water source is consumed.

[0033] A connecting plate 8 is fixedly installed on one side of the water storage barrel 1 away from the fixing plate 192 , and the bottom of the connecting plate 8 is fixedly connected to the placement frame 191 .

[0034] By adopting the above technical solution and providing the connecting plate 8, the water storage barrel 1 and the placement frame 191 can be connected.

[0035] Working principle: In actual use, water is poured into the water storage barrel 1. Through the sensor 193, when the mouse comes to the front of the water storage barrel 1, the sensor 193 causes the shaft 14 to rotate, and the shaft 14 drives the half-gear 13 to rotate, and the half-gear 13 drives the gear 12 to rotate, so that the gear 12 drives the rotating rod 11 and the connecting turntable 15 to rotate. When the connecting turntable 15 rotates to a certain angle, the first water outlet 16 and the second water outlet 17 overlap, so that the water source in the water storage barrel 1 enters the water collection frame 18 and falls into the placement frame 191 through the water pipe 19. When the half-gear 13 rotates to a certain angle, the teeth on the half-gear 13 are disengaged from the gear 12, so that the gear 12 stops rotating, driving the connecting turntable 1 5 stops rotating, at which time the first water outlet 16 and the second water outlet 17 are in a staggered state, thereby preventing the water in the water storage barrel 1 from entering the water collecting frame 18. The number of revolutions of the half-face gear 13 is set according to the amount of water the mouse needs to drink, so that when the mouse comes in front of the water storage barrel 1, water can be automatically discharged, avoiding the need for manual addition, and at the same time, the amount of water discharged can be controlled to avoid wasting water resources; by driving the movable rod 2 to rotate, the scraper 21 is driven to rotate, so that the scraper 21 scrapes off the water stains on the inner wall and the lower surface of the inner wall of the placement frame 191, and then pure water is poured into the placement frame 191 to clean it, avoiding the water stains from polluting the placement frame 191, and the cleaned waste water is discharged by removing the latch 22 from the placement frame 191.
