Description

Technical Field

[0001] The utility model relates to the technical field of laboratory animals, and particularly provides a drinking device for laboratory animals. Background Technique

[0002] Animal experiments refer to scientific research using animals to obtain new knowledge in biology, medicine, etc. or to solve specific problems. It can be seen from the "National Standard for Laboratory Animals GB14925 - 2010" in China that laboratory animals refer to animals that have been artificially bred, with control over the microorganisms and parasites they carry, clear genetic backgrounds or known origins, and are used for scientific research, teaching, production, verification, and other scientific experiments. The ultimate goal of the development of laboratory animal science is to study the life phenomena of animals themselves and then apply them to humans to explore the mysteries of human life, control human diseases and aging, and extend human lifespan. The research on these issues will ultimately have to be solved through animal experiments. When raising laboratory animals, a drinking device is needed for the animals to drink water.

[0003] According to a drinking device for raising laboratory animals disclosed in a Chinese patent with the publication number "CN219981826U", which relates to the field of raising laboratory animals, it includes a base. Multiple support frames are connected to the top of the base, a support plate is connected to the top of the support frames, a water tank is connected to the top of the support plate, a drinking platform is connected to the left side of the water tank, and a drinking groove is opened on the top of the drinking platform. In the utility model, through the pressure sensor set, by closing the first solenoid valve and opening the second solenoid valve, the drinking water enters into the drinking groove. Because there is a pressure sensor on the platform, laboratory animals can continuously drink water when standing on the platform. When the laboratory animals step off the platform, the pressure sensor cannot sense the laboratory animals, and the second solenoid valve is closed and the first solenoid valve is opened. The remaining drinking water in the drinking groove enters the water tank again through filtration, which can continuously supply water according to the water intake of the laboratory animals, and can conveniently filter the drinking water, so that it can be reused repeatedly, saving water resources.

[0004] However, when animals drink water, their hair is likely to fall into the drinking tray and float on the water surface. The bacteria carried by these hairs will cause a certain degree of pollution to the drinking water, thereby affecting the health of the animals. Therefore, a drinking device for laboratory animals is proposed to solve the above - mentioned problems. Content of the Utility Model

[0027] Please refer to Figures 1-4 , an embodiment of the present utility model is: a drinking water device for experimental animals, including a drinking water tank 1, and a cleaning mechanism 2 is arranged on the top of the drinking water tank 1; the cleaning mechanism 2 includes a horizontal chute 21, a horizontal sliding rod 22, a push plate 23, a limiting plate 24, a first spring 25, a motor 26, a transmission shaft 27, a semi-toothed gear 28, and a set of transmission teeth 29; the horizontal chute 21 is opened on the top of the drinking water tank 1, the horizontal sliding rod 22 is slidably connected inside the horizontal chute 21, the push plate 23 is fixedly connected to the middle of the horizontal sliding rod 22, the limiting plate 24 is fixedly connected to the left and right ends of the horizontal sliding rod 22, the first spring 25 is wound around the outside of the horizontal sliding rod 22, one end of the first spring 25 is fixedly connected to the limiting plate 24, and the other end of the first spring 25 away from the limiting plate 24 is fixedly connected to the outer wall of the drinking water tank 1. The horizontal sliding of the horizontal sliding rod 22 is limited by arranging the horizontal chute 21. The motor 26 is fixedly connected to the front outer wall of the drinking water tank 1, and the top output end of the motor 26 is fixedly connected to the bottom end of the transmission shaft 27. The drinking water tank 1 is arranged to provide a supporting force for the motor 26. The semi-toothed gear 28 is fixedly connected to the top end of the transmission shaft 27, a set of transmission teeth 29 is fixedly connected to the front of the horizontal sliding rod 22, and the semi-toothed gear 28 is in transmission connection with the transmission teeth 29.

[0028] Working principle: Before the animal drinks water, the motor 26 is started to drive the transmission shaft 27 to rotate. The rotation of the transmission shaft 27 drives the semi-toothed gear 28 to rotate. In the first half of the rotation of the semi-toothed gear 28, the transmission tooth 29 drives the transverse slide bar 22 to move to the right and compress the first spring 25. The rightward movement of the transverse slide bar 22 drives the push plate 23 to move to the right. During the rightward movement of the push plate 23, the hair floating on the water surface and the water are pushed to the right together and pushed into the return water tank 3. When the semi-toothed gear 28 rotates to the second half of the cycle, it disengages from the transmission tooth 29. At this time, the first spring 25 rebounds to drive the transverse slide bar 22 to return to its original position.

[0029] Please refer to Figures 1-4 , on the basis of the above embodiment, in another embodiment of the present utility model, a return water tank 3 is fixedly connected to the right side of the drinking water tank 1. A filtering mechanism 4 is arranged inside the return water tank 3. The filtering mechanism 4 includes a vertical sliding groove 41. The vertical sliding groove 41 is opened on the inner walls of the front and rear sides of the return water tank 3. A slider is slidably connected inside the vertical sliding groove 41. A filter plate 42 is fixedly connected between the two sliders. The vertical sliding groove 41 is provided to limit the up and down movement of the filter plate 42. The top of the filter plate 42 is fixedly connected with a first trapezoidal top block 44 through a vertical rod 43. A second trapezoidal top block 45 is fixedly connected to one side of the right limiting plate 24. The first trapezoidal top block 44 is slidably connected with the second trapezoidal top block 45. A second spring 46 is sleeved outside the vertical rod 43. The top end of the second spring 46 is fixedly connected with the first trapezoidal top block 44, and the second spring 46 is fixedly connected with the inner wall of the return water tank 3. The second spring 46 is provided to drive the filter plate 42 to return to its original position. A water pump 5 is fixedly connected to the right side of the return water tank 3. The top water outlet end of the water pump 5 is fixedly connected with a return water pipe 6. The right end of the return water pipe 6 is fixedly connected with an electric nozzle 7.

[0030] Working principle: During the rightward movement of the transverse slide bar 22, it drives the second trapezoidal top block 45 to move to the right. During the rightward movement of the second trapezoidal top block 45, it pushes the first trapezoidal top block 44 downward. The downward movement of the first trapezoidal top block 44 drives the vertical rod 43 to move downward. The downward movement of the vertical rod 43 drives the filter plate 42 to move downward and compress the second spring 46. Subsequently, the transverse slide bar 22 drives the limiting plate 24 and the second trapezoidal top block 45 to move to the left. At this time, the first trapezoidal top block 44 moves upward under the action of the restoring force of the second spring 46 and drives the vertical rod 43 and the filter plate 42 to move upward. Repeating this way, the filter plate 42 makes a reciprocating up and down movement, which speeds up the filtering speed of the filter plate 42 for water and animal hair. The filtered clean water will flow into the bottom of the return water tank 3, and the water pump 5 pumps the clean water in the return water tank 3 into the return water pipe 6 and sprays it back into the drinking water tank 1 through the electric nozzle 7.

The above description is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. Each component not clearly defined in this embodiment can be implemented by using the prior art.
