Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and more specifically, to a sterile feeding device for experimental animals used in basic research of traditional Chinese and Western medicine. Background Technology

[0002] Laboratory animals generally refer to animals specifically used for scientific research, teaching, production and other experimental activities. These animals play a vital and irreplaceable role in promoting progress in many fields such as life sciences, medicine, and pharmacy. There are many types of laboratory animals, including mice, rats, rabbits, guinea pigs, dogs, monkeys, etc. Different types of laboratory animals have different characteristics and applicable ranges. Researchers need to select appropriate laboratory animals according to specific experimental needs.

[0003] Currently, when operators conduct research on traditional Chinese and Western medicine drugs and technologies, they often need to conduct experiments on animals to determine the efficacy and effects of these technologies for future application. When conducting animal experiments, aseptic feeding equipment is generally required to effectively prevent the intrusion of bacteria, viruses, and other harmful microorganisms, ensuring the health and safety of the experimental animals. However, while existing aseptic feeding equipment has basic aseptic feeding functions, uneaten food residue often remains in the feeding troughs during animal feeding. This residue can breed bacteria inside the feeding equipment, requiring operators to frequently clean the troughs, which is inconvenient and necessitates improvement. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 6 As shown, this utility model provides a sterile animal husbandry device for basic research in traditional Chinese and Western medicine, including a feeding chamber 1. A feeding trough 2 is fixedly connected to the inner surface of the feeding chamber 1. The rear end of the feeding trough 2 penetrates the feeding chamber 1 and extends to the outside of the feeding chamber 1. A pusher plate 3 is movably connected to the front side of the inner surface of the feeding trough 2. A connecting plate 4 is fixedly connected to the upper surface of the pusher plate 3. A first connecting rod 5 is movably connected to the top of the outer surface of the connecting plate 4. A connecting shaft 6 is fixedly sleeved on the inner surface of the right end of the first connecting rod 5. The top end of the outer surface of the connecting shaft 6 penetrates the feeding chamber 1 and extends above the feeding chamber 1, and a second connecting rod 7 is fixedly sleeved on it. A moving block 8 is movably connected to the inner surface of the second connecting rod 7. A device located in front of the moving block 8 is fixedly connected to the upper surface of the feeding chamber 1. The fixed plates 9 on both sides are fixed. A motor 10 is fixedly installed on the right surface of the fixed plate 9. A lead screw 11 is fixedly sleeved at the other end of the output shaft of the motor 10. The other end of the lead screw 11 passes through the fixed plate 9 and the moving block 8 and extends to the left side of the fixed plate 9. The outer surface of the lead screw 11 and the inner surface of the moving block 8 are threaded together. The operation of the motor 10 will cause the lead screw 11 to start rotating. At this time, the moving block 8 will start to move under the drive of the lead screw 11. The movement of the moving block 8 will drive the second connecting rod 7, so that the second connecting rod 7, the connecting shaft 6 and the first connecting rod 5 will all start to rotate around the connecting shaft 6. At the same time, the rotation of the first connecting rod 5 will drive the connecting plate 4, so that the connecting plate 4 and the push plate 3 will start to move.

[0023] The left side of the inner surface of the fixed plate 9 is fixedly connected to a limiting rod 28 located behind the lead screw 11. The right end of the limiting rod 28 passes through the moving block 8 and extends to the right side of the inner surface of the fixed plate 9 and is fixedly connected to the fixed plate 9. The rear surface of the feeding chamber 1 is fixedly installed with a second motor 12. The other end of the output shaft of the second motor 12 is fixedly sleeved with a round shaft 13. The outer surface of the round shaft 13 is fixedly sleeved with a sealing plate 14. The front surface of the sealing plate 14 is movably connected to the rear surface of the feeding chamber 1 and the rear end of the feeding trough 2. The sealing plate 14 acts as a seal for the rear end of the feeding trough 2. When the operator needs to clean the inside of the feeding trough 2, the operator starts the second motor 12. As the second motor 12 runs, the round shaft 13 and the sealing plate 14 will start to rotate, eventually causing the sealing plate 14 to release the seal for the rear end of the feeding trough 2.

[0024] The inner surface of the feeding chamber 1 is fixedly connected to a cleaning liquid box 15 located above the feeding trough 2. The front end of the cleaning liquid box 15 penetrates through the feeding chamber 1 and extends to the outside of the feeding chamber 1. A nozzle 16 is fixedly installed on the inner surface of the cleaning liquid box 15. The outer end of the nozzle 16 penetrates through the cleaning liquid box 15 and extends to the outside of the cleaning liquid box 15. The cleaning liquid box 15 contains a bactericidal cleaning liquid mainly composed of alcohol solution. When the nozzle 16 is opened, the bactericidal cleaning liquid inside the cleaning liquid box 15 will be sprayed into the interior of the feeding trough 2 through the nozzle 16, thereby achieving the bactericidal and disinfecting effect on the interior of the feeding trough 2.

[0025] A heating plate 17 is fixedly installed on the inner surface of the feeding trough 2. The outer surfaces of the front and rear sides of the heating plate 17 are fixedly connected to the inner surface of the feeding chamber 1. When the sterilizing cleaning liquid is sprayed into the interior of the feeding trough 2, the heating plate 17 will heat the interior of the feeding trough 2. This can not only kill the stubborn bacteria inside the feeding trough 2, but also accelerate the evaporation of the sterilizing cleaning liquid inside the feeding trough 2, thereby preventing water from remaining inside the feeding trough 2.

[0026] The front surface of the cleaning liquid box 15 is fixedly equipped with a liquid pump 21, and the rear surface of the liquid pump 21 is fixedly connected with a liquid outlet pipe 23. The rear end of the liquid outlet pipe 23 passes through the cleaning liquid box 15 and extends into the interior of the cleaning liquid box 15. The top of the outer surface of the liquid outlet pipe 23 is fixedly connected with an inlet pipe 22 located outside the feeding chamber 1. The top end of the inlet pipe 22 is connected to a sterilization cleaning liquid delivery pipe. When the liquid pump 21 is started, the sterilization cleaning liquid will enter the interior of the liquid pump 21 through the inlet pipe 22, and then enter the interior of the cleaning liquid box 15 along the liquid outlet pipe 23, thereby replenishing the sterilization cleaning liquid inside the cleaning liquid box 15.

[0027] The upper surface of the feeding chamber 1 is fixedly equipped with a fan 18, and the upper surface of the fan 18 is fixedly connected with an air inlet pipe 19. The lower surface of the air inlet pipe 19 is fixedly connected with an air outlet pipe 20. The bottom end of the air outlet pipe 20 passes through the feeding chamber 1 and extends into the interior of the feeding chamber 1. The top end of the air inlet pipe 19 is connected to a sterile air delivery pipe. When the fan 18 is started, sterile air will enter the interior of the fan 18 through the air inlet pipe 19 for heating. The heated sterile air will continue to enter the interior of the feeding chamber 1 along the air outlet pipe 20, thereby realizing the function of regulating and controlling the internal temperature of the feeding chamber 1.

[0028] The left end of the outer surface of the feeding chamber 1 is fixedly connected to the mounting plate 24. The outer surface of the mounting plate 24 is fixedly mounted with a No. 3 motor 25. The other end of the output shaft of the No. 3 motor 25 is fixedly sleeved with a rotating shaft 26. The other end of the rotating shaft 26 passes through the mounting plate 24 and extends to the rear side of the mounting plate 24. The outer surface of the rotating shaft 26 is fixedly sleeved with a rotating plate 27 located between the mounting plates 24. When the No. 3 motor 25 is started, the rotating shaft 26 starts to rotate, which causes the rotating plate 27 to start to rotate around the rotating shaft 26. Finally, as the rotating plate 27 rotates, the rotating plate 27 will fit against the left surface of the feeding chamber 1 and seal the left surface of the feeding chamber 1.

[0029] Working principle and usage process of this utility model:

[0030] When food residue from laboratory animals remains inside the feeding trough 2, the operator starts motor 10. As motor 10 operates, lead screw 11 begins to rotate, causing moving block 8 to move to the left under the limit of limit rod 28. The movement of moving block 8 drives connecting rod 7, causing connecting rod 7, connecting shaft 6, and connecting rod 5 to rotate around connecting shaft 6. During this process, the inner surface of connecting rod 5 drives connecting plate 4, causing connecting plate 4 and pusher plate 3 to move backward along the inner surface of feeding trough 2. As pusher plate 3 moves, food residue inside feeding trough 2 is pushed backward by pusher plate 3. Finally, this food residue is pushed out to the outside of feeding chamber 1, thus completing the cleaning of the inside of feeding trough 2.

[0031] Then the operator starts the liquid pump 21 and opens the nozzle 16. As the liquid pump 21 runs, the disinfectant cleaning solution will enter the cleaning solution box 15 through the inlet pipe 22, the liquid pump 21 and the outlet pipe 23 in sequence, and then be sprayed into the interior of the feed trough 2 through the nozzle 16. At this time, the bacteria that may exist in the feed trough 2 will be killed by the alcohol in the disinfectant cleaning solution, thereby eliminating the possibility of bacteria growing in the feed trough 2.
