Description

Technical Field

[0001] This utility model belongs to the technical field of drinking devices, specifically a drinking device for laboratory animals. Background Technology

[0002] In the field of laboratory animal breeding and research, the health status of laboratory animals directly affects the accuracy and reliability of experimental results. Water supply, as a crucial link in ensuring the health of laboratory animals, places strict requirements on the stability, hygiene, and functionality of watering devices. Currently, in laboratory animal breeding settings, watering devices must meet the continuous water supply needs of a large number of animals, while also adapting to special needs such as drug administration and water quality maintenance that may arise during experiments. This ensures that laboratory animals receive clean, sufficient, and experimentally appropriate drinking water throughout their entire rearing cycle, preventing health abnormalities caused by water problems and thus affecting the validity of experimental data. In the existing technology, laboratory animal drinking devices are mainly divided into two categories: manual water replenishment type and simple automatic water replenishment type. Manual water replenishment type devices are mostly simple water storage containers combined with drinking troughs, while simple automatic water replenishment type devices mostly achieve automatic water replenishment through float valves or liquid level sensors.

[0003] However, most simple automatic water replenishment devices have poor compatibility between their water control components and the matching structure. They are prone to water control failure due to component wear and impurity blockage, making it impossible to stably maintain a suitable water level in the drinking trough. They also lack dedicated drug delivery channels and stirring structures, making the powder addition operation cumbersome and difficult to mix thoroughly with water, resulting in uneven drug concentration, affecting the drug efficacy in experimental animals, and increasing the risk of experimental errors. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a drinking device for laboratory animals, which solves the technical deficiencies mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water drinking device for laboratory animals, comprising a water storage cylinder, a first cover threadedly connected to the top of the water storage cylinder, a drain pipe connected to the bottom of the water storage cylinder, a drinking block threadedly connected to the end of the drain pipe, a partition fixedly connected inside the drinking block, a float plate disposed above the partition plate inside the drinking block, multiple sets of connecting rods fixedly connected to the bottom of the float plate, a second blocking block connected to the bottom of the connecting rods, an opening provided inside the partition plate for use with the connecting rods and the second blocking block, the top of the float plate having a concave structure and a drinking port provided at the center of the float plate.

[0006] As a further embodiment of this utility model: a motor is embedded in the first cover, and an output rod is coaxially fixedly connected to the output end of the motor. The other end of the output rod passes through and extends out of the first cover. A stirring rod is snapped to the end of the output rod. A first blocking block for use with the motor is provided at the top of the first cover. A switch for use with the motor is provided at the top of the first blocking block.

[0007] As a further embodiment of this utility model: a water inlet pipe is connected to the lower side of one side of the water storage cylinder, a water inlet block is provided at the top of the water inlet pipe, and a second cover is snapped onto the top of the water inlet block.

[0008] As a further embodiment of this utility model: a connecting block is fixedly connected to the outside of the water storage cylinder in a symmetrical structure, and a slot is opened in the connecting block.

[0009] As a further embodiment of this utility model: the outer diameter of the second blocking block is smaller than the inner diameter of the opening, and a baffle with a semi-circular structure is provided on the top of the drinking block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The first cover at the top of the water tank is threaded, ensuring a good seal and effectively preventing dust and debris from falling into the water and contaminating the water source, thus ensuring drinking water hygiene. The automatic water control structure, consisting of a float plate, connecting rod, and second stop block inside the water block, allows for automatic water replenishment and shut-off without manual operation. It automatically replenishes water when the water level in the water block is low and automatically stops when the water level reaches a certain height. This avoids both insufficient water leading to dehydration for animals and excessive water overflow causing waste and a damp environment. Furthermore, the float plate's concave top design with a central drinking spout conforms to animal drinking habits, facilitating easy drinking. The float plate also partially shields the water surface, reducing dust ingress and water evaporation, further maintaining water cleanliness and stable water supply. Attached Figure Description

Detailed Implementation

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figures 1-5 As shown, this utility model provides a technical solution: A laboratory animal drinking device includes a water storage cylinder 1, a first cover 2 threadedly connected to the top of the water storage cylinder 1, a drain pipe 3 connected to the bottom of the water storage cylinder 1, a drinking block 4 threadedly connected to the end of the drain pipe 3, a partition 16 fixedly connected inside the drinking block 4, a float plate 14 disposed above the partition 16 inside the drinking block 4, a plurality of connecting rods 17 fixedly connected to the bottom of the float plate 14, a second block 18 connected to the bottom of the connecting rods 17, an opening 19 in the partition 16 for use with the connecting rods 17 and the second block 18, and a drinking port at the center of the float plate 14 with a concave top structure. Specifically, during use, open the first cap 2, which is threaded to the top of the water storage cylinder 1, and inject sufficient water into the water storage cylinder 1. After filling with water, screw the first cap 2 back onto the top of the water storage cylinder 1 to achieve a sealed water storage. Then, since the bottom of the water storage cylinder 1 is connected to the drain pipe 3, and the end of the drain pipe 3 is connected to the drinking block 4, in the initial state, the float plate 14 above the partition 16 inside the drinking block 4 is in a low position because it is not in contact with water. At this time, the second block 18 connected to the bottom of the float plate 14 through the connecting rod 17 is not in contact with the partition 16. The opening 19 is blocked, and the water in the water storage tank 1 flows into the space above the partition 16 in the drinking block 4 through the drain pipe 3. As the water continues to flow in, the water level above the partition 16 in the drinking block 4 gradually rises, causing the float plate 14 to float upward. During the rise of the float plate 14, the second block 18 is pulled up synchronously through the connecting rod 17. When the water level rises to a certain height, the second block 18 will just block the opening 19 on the partition 16, thereby preventing the water in the water storage tank 1 from continuing to flow into the drinking block 4 and avoiding water overflow. When the animal needs to drink, it will drink the water above the partition 16 through the drinking port in the center of the float plate 14. As the water is consumed, the water level in the drinking block 4 gradually drops, and the float plate 14 also drops. The second block 18 leaves the opening 19 under the action of the connecting rod 17, and the water in the water storage tank 1 flows into the drinking block 4 again through the drain pipe 3. This cycle ensures that the drinking block 4 always has an appropriate amount of water for the animal to drink. The first cover 2 at the top of the water storage tank 1 is connected by a thread, which has good sealing performance and can effectively prevent dust and debris from falling into the water and contaminating the water source, ensuring drinking water hygiene. In addition, the automatic water control structure composed of the float plate 14, connecting rod 17 and second block 18 in the drinking block 4 can realize automatic water replenishment and water stop without manual operation. When the water level in the drinking block 4 is insufficient, it will automatically replenish and automatically stop when the water level reaches a certain height. This not only avoids the animals from being dehydrated due to insufficient water, but also prevents excessive water from overflowing and causing waste and a damp environment. In addition, the top of the float plate 14 is designed with a concave structure and a drinking port in the center, which conforms to the animals' drinking habits and makes it easy for the animals to drink. At the same time, the float plate 14 can also block the water surface to a certain extent, reducing dust falling in and water evaporation, further maintaining water quality and water quantity stability. A motor 13 is embedded in the first cover 2. An output rod 15 is coaxially fixedly connected to the output end of the motor 13. The other end of the output rod 15 passes through and extends out of the first cover 2. A stirring rod 12 is snapped to the end of the output rod 15. A first block 7 for use with the motor 13 is set at the top inside the first cover 2. A switch 8 for use with the motor 13 is set at the top of the first block 7. A water inlet pipe 9 is connected to the lower side of the water storage cylinder 1. A water inlet block 10 is set at the top of the water inlet pipe 9. A second cover 11 is snapped to the top of the water inlet block 10. A connecting block 6 is fixedly connected to the outside of the water storage cylinder 1 in a symmetrical structure. A slot is opened in the connecting block 6. The outer diameter of the second block 18 is smaller than the inner diameter of the opening 19. A baffle 5 with a semi-circular structure is set at the top of the drinking block 4. Specifically, when it is necessary to add medicine powder or medicine solution to the water storage tank 1, since the water inlet pipe 9 is located below the water storage tank 1, it is not necessary to store a large amount of water in the water storage tank 1. Just open the second cover 11 connected by the buckle on the top of the water inlet block 10, and pour the medicine powder or medicine solution into the water inlet pipe 9 through the water inlet block 10. The medicine powder or medicine solution flows into the water storage tank 1 along the water inlet pipe 9. If a small amount of water is needed to assist in dissolution, an appropriate amount of water can be added through the water inlet block 10. Then press the switch 8 inside the top of the first cover 2, which is used in conjunction with the motor 13. At this time, the first block 7 does not obstruct the motor 13. After the motor 13 starts, it drives the coaxial fixed output rod 15 to rotate. The output rod 15 then drives the stirring rod 12, which is connected by a snap-fit ​​at the end, to rotate inside the water storage tank 1. During the rotation of the stirring rod 12, the powder and water can be fully mixed to avoid the powder settling and uneven efficacy. After the mixing is complete, turn off the switch 8. Throughout the entire process, the symmetrically fixed connecting blocks 6 on the outside of the water storage cylinder 1 can fix the device in a suitable position through the internal slots to prevent the device from tipping over. The semi-circular baffle 5 on the top of the drinking block 4 can block dust and debris from falling into the drinking area and also prevent water from splashing out when the animal drinks. At the same time, the design of the outer diameter of the second block 18 being smaller than the inner diameter of the opening 19 ensures that the second block 18 moves smoothly up and down. The working principle of this utility model is as follows: First, the water storage cylinder 1 is sealed and stores water through the first cover 2 connected by the top thread. In the initial state, the floating plate 14 above the partition 16 inside the drinking block 4 is in a low position due to the lack of water pressure. The second block 18 connected to the bottom by the connecting rod 17 does not block the opening 19 of the partition 16. The water in the water storage cylinder 1 flows into the drinking block 4 through the drain pipe 3 connected to the bottom. As the water level in the drinking block 4 rises, the floating plate 14 floats upwards due to buoyancy, and the second blocking block 18 rises synchronously through the connecting rod 17 until the second blocking block 18 blocks the opening 19 and stops the water from entering. When the animal drinks through the central drinking port of the floating plate 14, the water level drops, the floating plate 14 and the second blocking block 18 move down, the opening 19 reopens, and the water storage tank 1 is replenished with water again, forming an automatic circulating water supply. Secondly, the device enables convenient drug administration through the water inlet pipe 9 at the bottom of one side of the water storage cylinder 1. There is no need to store a large amount of water in the water storage cylinder 1. By opening the second cover 11 connected to the top of the water inlet block 10, the powder or liquid medicine can be poured into the water storage cylinder 1 through the water inlet block 10 and the water inlet pipe 9. If a small amount of water is needed to assist in dissolving, it can be added at the same time. Then press the switch 8 at the top inside the first cover 2 to start the embedded motor 13. The motor 13 drives the coaxial fixed output rod 15 to rotate. The output rod 15 then drives the stirring rod 12, which is connected to the end by a snap-fit, to rotate inside the water storage tank 1, so as to fully mix the powder and water, avoid sedimentation and affect the efficacy. After mixing, turn off the switch 8 to stop stirring, thus meeting the drinking water needs of animals for medication. It is worth mentioning that the connecting block 6, which is fixed to the outside of the water storage cylinder 1 with a symmetrical structure, has a slot inside that can fix the device in a suitable position to prevent animals from colliding with it and causing it to tip over. The semi-circular baffle 5 on the top of the drinking block 4 can effectively block dust and debris from falling into the drinking area, while preventing water from splashing out when animals drink, keeping the surrounding environment dry and clean. The first block 7 on the top of the first cover 2, in conjunction with the motor 13, can limit and protect the motor 13, ensuring stable operation of the motor 13 and extending the service life of the components. Finally, the first cover 2 uses a threaded connection, which has excellent sealing performance and can prevent dust and debris from falling into the water storage tank 1 and contaminating the water source, ensuring drinking water hygiene. The top of the float plate 14 is designed with a concave structure, which conforms to the animal's drinking habits and makes it easy for the animal to drink water smoothly. At the same time, the float plate 14 can block the water surface, reducing water evaporation and dust falling in. The design of the outer diameter of the second block 18 being smaller than the inner diameter of the opening 19 ensures that the second block 18 moves up and down without jamming, ensuring the smooth operation of the automatic water control structure and avoiding abnormal water supply due to component jamming, thus improving the overall reliability of the device.
