Description

Technical Field

[0001] The present application relates to the technical field of animal water feeding, and in particular to an automatic drinking water device for experimental animals. Background Art

[0002] Laboratory animals are human stand-ins and are often called "living experimental instruments." Mice are the most common of these animals and are often housed in groups. Each cage must be fed sterile feed and drinking water.

[0003] Chinese patent publication number CN205492053U discloses a laboratory sealed animal cage with intelligent monitoring function, including a box with a cavity inside, an animal water bottle, a feed box and a touch sensor, wherein the touch sensor is arranged at the drinking spout of the animal water bottle.

[0004] The above technology uses animal water bottles to feed water to animals, but there are usually many animals raised in the laboratory, and a separate water bottle requires a lot of manual work to fill it with water, which increases the workload of the experimenters. At the same time, if the water bottle is not replenished with water in time, it is easy to cause a large change in the physical condition characteristics of the animal, which can easily lead to large deviations in the animal experimental data, and there are shortcomings. Utility Model Content

[0005] In order to improve the inconvenience of changing water for a large number of experimental animals in sequence, the present application provides an automatic drinking water device for experimental animals.

[0006] The present application provides an automatic drinking water device for experimental animals adopting the following technical solutions:

[0007] An automatic drinking water device for experimental animals includes a tank rack and a water tank, wherein the water tank is connected to a main water pipe, the tank rack is vertically provided with a multi-layer box placement plate, and a plurality of feeding boxes are arranged along the length direction of the box placement plate, the main water pipe is connected to a plurality of branch pipes, the branch pipes correspond one-to-one with the box placement plate, the branch pipes are provided with a plurality of drinking spouts, the drinking spouts correspond one-to-one with the feeding boxes, and the water tank is provided with a water replenishment component for replenishing water.

[0008] By adopting the above technical solution, the water replenishing component replenishes the water storage tank in time, and then the water storage tank supplies water to all the feeding boxes on the box rack through the main water pipe and the branch pipe at the same time. The animals in the feeding boxes can be replenished with water in time through the drinking spouts. The experimenters do not need to replenish water for each feeding box in turn, and do not need to check each water bottle in turn, which greatly reduces the labor intensity of the experimenters and reduces the cross-contamination problem in the traditional water bottle filling, which is conducive to improving the accuracy of the animal experimental data.

[0009] Optionally, the water replenishment component includes a water inlet pipe connected to the water tank, the water inlet pipe is used to connect to the water dispenser, the water inlet pipe is provided with a water replenishment pump electrically connected to the control system, and the water tank is provided with a liquid level sensor electrically connected to the control system.

[0010] By adopting the above technical solution, when the liquid level in the water tank drops and triggers the liquid level sensor, the liquid level sensor will feed back information to the control system, and the control system will start the water replenishment pump. The water replenishment pump draws the water in the water dispenser into the water tank through the water inlet pipe, thereby replenishing the water tank in time and reducing the secondary pollution problem that may exist when people replenish water. When the water tank is not replenished with water for a long time, the control system will alert the experimenters through an external alarm.

[0011] Optionally, a water storage bottle is provided between the drinking spout and the branch pipe, an intermediate valve is provided between the water storage bottle and the branch pipe, and the drinking spout is detachably provided on the water storage bottle.

[0012] By adopting the above technical solution, the water storage bottle can provide a stable amount of water for the animals in the breeding box, making it convenient for the animals to drink water in time. When the drinking nozzle has been used for a period of time, the experimenter first closes the middle valve, and then disassembles and replaces the new drinking nozzle, which facilitates the timely replacement of the drinking nozzle and the timely cleaning of the drinking nozzle, thereby reducing the possibility of the drinking nozzle being contaminated by long-term use.

[0013] Optionally, the drinking spout includes a drinking tube bolted to the water storage bottle, a rotating shaft is rotatably provided in the drinking tube and at the water outlet end of the drinking tube, a drinking rod is provided on the rotating shaft, one end of the drinking rod extends to the outside of the drinking tube, and a drinking spoon with a C-shaped cross-section is provided at the end of the drinking rod facing away from the drinking tube, a drinking trough is provided on the drinking rod and connected to the concave side of the drinking spoon, the drinking trough is used to connect with the inside of the drinking tube, and a sealing member for sealing the drinking trough is provided on the drinking tube.

[0014] By adopting the above technical solution, the experimental animals inside the breeding box touch the drinking spoon, and the drinking spoon drives the drinking rod to rotate around the rotating axis, so that the drinking trough on the drinking rod is connected with the inside of the drinking pipe, and the water inside the drinking pipe flows through the drinking trough on the drinking rod to the concave side of the drinking spoon, and then the experimental animals drink the water in the drinking spoon.

[0015] Optionally, the drinking water pipe is arranged at an angle at the bottom of the water storage bottle, and the water outlet end of the drinking water pipe extends to the water feeding place of the breeding box.

[0016] By adopting the above technical solution, the water in the water storage bottle can flow smoothly through the water trough on the drinking rod to the drinking spoon, making it convenient for animals to drink in time.

[0017] Optionally, the blocking member includes a flow-stop protrusion arranged on the water outlet end of the drinking pipe, the flow-stop protrusion is located between the rotating shaft and the drinking spoon, and a compression spring is supported between the side of the drinking rod facing away from the flow-stop protrusion and the drinking pipe, and the compression spring is used to press the drinking trough on the drinking rod against the flow-stop protrusion.

[0018] By adopting the above technical solution, when the experimental animal presses the drinking spoon, the drinking spoon drives the drinking rod to rotate, the compression spring is forced to contract, the drinking trough on the drinking rod is separated from the flow-stop protrusion, and the water in the drinking pipe can flow out through the drinking trough on the drinking rod. When the animal releases the drinking spoon, the compression spring recovers its deformation and presses the drinking trough on the drinking rod against the flow-stop protrusion, thereby achieving the blocking effect of the drinking trough.

[0019] Optionally, the inner diameter of the drinking water tube gradually increases along the direction from the rotating shaft to the water storage bottle, a float is provided in the drinking water tube, the float is used to block the inner diameter of the drinking water tube, and a pull rope is provided between the side of the drinking water rod facing away from the compression spring and the float.

[0020] By adopting the above technical solution, when the drinking spoon is pressed and drives the drinking rod to the maximum angle, the drinking rod rotates and pulls the pull rope, the pull rope pulls the float, and the float blocks the inner diameter of the drinking pipe, thereby preventing the water inside the drinking pipe from continuously flowing out. The water flow on the drinking rod is interrupted, which is beneficial to reduce the possibility of cross-contamination through water flowing in the drinking trough when experimental animals drink water, and is beneficial to reduce the frequency of replacing the drinking spout, while achieving the effect of quantitative water feeding.

[0021] Optionally, a leak-proof rubber block is provided between the end of the drinking rod facing away from the drinking spoon and the inner wall of the drinking tube.

[0022] By adopting the above technical solution, the anti-leakage rubber block continuously deforms during the rotation of the drinking rod, thereby preventing the water in the drinking pipe from flowing out through the gap between the drinking pipe and the drinking rod.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The water replenishment component replenishes the water storage tank in time, and then the water storage tank supplies water to all the feeding boxes on the box rack through the main water pipe and branch pipes at the same time. The animals in the feeding boxes can be replenished with water in time through the drinking spouts. The experimenter does not need to replenish water in each feeding box in turn, and there is no need to check each water bottle in turn, which greatly reduces the labor intensity of the experimenter and reduces the cross contamination problem in the traditional water bottle filling, which is conducive to improving the accuracy of the animal experimental data;

[0025] 2. When the experimental animal presses the drinking spoon, the drinking spoon drives the drinking rod to rotate, the compression spring is forced to contract, and the drinking trough on the drinking rod is separated from the flow-stopping protrusion. The water in the drinking pipe can flow out through the drinking trough on the drinking rod. When the animal releases the drinking spoon, the compression spring recovers its deformation and presses the drinking trough on the drinking rod tightly against the flow-stopping protrusion, thereby achieving the effect of blocking the drinking trough;

[0026] 3. When the drinking spoon is pressed and drives the drinking rod to the maximum angle, the drinking rod rotates and pulls the pull rope, which pulls the float. The float blocks the inner diameter of the drinking pipe, thereby preventing the water inside the drinking pipe from continuously flowing out. The water flow on the drinking rod is interrupted, which is beneficial to reduce the possibility of cross-contamination through the water flowing in the drinking trough when the experimental animals drink water, which is beneficial to reduce the frequency of changing the drinking nozzle and can achieve the effect of quantitative water feeding.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses an automatic drinking water device for experimental animals.

[0034] Reference Figure 1An automatic drinking water device for experimental animals includes a box frame 1 and a water tank 2. The water tank 2 is arranged on the top of the box frame 1 and is bolted with an alarm 14. The alarm 14 is electrically connected to the control system. The bottom of the water tank 2 is connected to a main water pipe 3. A plurality of horizontal box plates 4 are vertically and evenly welded on the box frame 1. A plurality of feeding boxes 5 are placed along the length direction of the box plates 4. A plurality of branch pipes 6 are connected to the main water pipe 3, and the branch pipes 6 correspond one to one to the box plates 4.

[0035] Reference Figure 1 and Figure 2 A plurality of drinking nozzles 7 are arranged on the branch pipe 6, and the drinking nozzles 7 correspond to the feeding boxes 5 one by one. A water replenishment component 8 for replenishing water is arranged on the water storage tank 2. The water replenishment component 8 includes a water inlet pipe 81 connected to the top of the water storage tank 2. The water inlet pipe 81 is used to communicate with an external sterile water dispenser (not shown in the figure). A water replenishment pump 82 electrically connected to the control system is bolted to the water inlet pipe 81, and liquid level sensors 83 electrically connected to the control system are bolted to the top and bottom of the water storage tank 2.

[0036] When the liquid level in the water tank 2 continues to drop and triggers the liquid level sensor 83 at the bottom of the water tank 2, the liquid level sensor 83 feeds back information to the control system, and the control system starts the water supply pump 82. The water supply pump 82 pumps the water in the water dispenser into the water tank 2 through the water inlet pipe 81, causing the liquid level in the water tank 2 to rise and trigger the liquid level sensor 83 at the top of the water tank 2. At this time, the control system controls the water supply pump 82 to stop working.

[0037] When the liquid level sensor 83 at the bottom of the water tank 2 is triggered and the liquid level does not change for a long time, the control system activates the alarm 14, and the alarm 14 sounds an alarm to remind the experimenter to replenish water. The sterile water in the water tank 2 flows to each drinking nozzle 7 through the main water pipe 3 and the branch pipe 6, and the animals in the breeding box 5 can automatically replenish water through the drinking nozzle 7.

[0038] Reference Figure 1 、 Figure 3 and Figure 4 A water storage bottle 9 is connected between the drinking nozzle 7 and the branch pipe 6, and an intermediate valve 10 is connected between the water storage bottle 9 and the branch pipe 6. The drinking nozzle 7 includes a drinking pipe 71 bolted to the bottom of the water storage bottle 9 and inclined. The water outlet end of the drinking pipe 71 extends to the water feeding place of the feeding box 5. A rotating shaft 72 is rotatably connected in the drinking pipe 71 and located at the water outlet end of the drinking pipe 71, and a drinking rod 73 is welded on the rotating shaft 72.

[0039] Reference Figure 1 、 Figure 3 and Figure 4One end of the drinking rod 73 extends to the outside of the drinking pipe 71, and the end of the drinking rod 73 facing away from the drinking pipe 71 is integrally formed with a drinking spoon 74 with a C-shaped cross section. A drinking trough 75 is provided on the drinking rod 73 and connected to the concave side of the drinking spoon 74. The drinking trough 75 is used to communicate with the inside of the drinking pipe 71, and a leak-proof rubber block 13 is arranged between the end of the drinking rod 73 facing away from the drinking spoon 74 and the inner wall of the drinking pipe 71. The leak-proof rubber block 13 can be made of flexible rubber material.

[0040] Reference Figure 1 、 Figure 3 and Figure 4 A sealing member 76 for sealing the drinking trough 75 is arranged on the drinking water pipe 71. The sealing member 76 includes a flow-stopping protrusion 761 integrally formed on the inner side wall of the water outlet end of the drinking water pipe 71. The flow-stopping protrusion 761 is located between the rotating shaft 72 and the drinking water spoon 74. A compression spring 762 is supported between the side of the drinking water rod 73 facing away from the flow-stopping protrusion 761 and the drinking water pipe 71. The compression spring 762 is located between the rotating shaft 72 and the drinking water spoon 74.

[0041] Reference Figure 1 、 Figure 3 and Figure 4 The compression spring 762 is used to press the drinking trough 75 on the drinking rod 73 onto the flow-stop protrusion 761. The inner diameter of the drinking pipe 71 gradually increases along the direction from the rotating shaft 72 to the water storage bottle 9. A float 11 is arranged in the drinking pipe 71. The float 11 is used to block the inner diameter of the drinking pipe 71. A pull rope 12 is tied between the side of the drinking rod 73 facing away from the compression spring 762 and the float 11.

[0042] The animals in the feeding box 5 press the drinking spoon 74, and the drinking spoon 74 drives the drinking rod 73 to rotate around the rotating shaft 72. The compression spring 762 is forced to contract, so that the drinking trough 75 on the drinking rod 73 is separated from the flow-stop protrusion 761, and the water in the drinking pipe 71 can flow out through the drinking trough 75 on the drinking rod 73 and flow into the drinking spoon 74. The drinking spoon 74 continues to rotate under the pressure of the animals until the drinking spoon 74 stops rotating. At this time, the drinking rod 73 will pull the float 11 through the pull rope 12, and the float 11 will drop and block the inner diameter of the drinking pipe 71.

[0043] During this process, the leak-proof rubber block 13 continuously deforms to block the gap between the drinking water pipe 71 and the drinking water rod 73. When the animal stops pressing, the compression spring 762 recovers its deformation and pushes the drinking water rod 73 to reset. The drinking trough 75 on the drinking water rod 73 is pressed against the flow-stop protrusion 761 again, and the sterile water in the drinking water pipe 71 is never prevented from continuing to flow. The animal can drink the sterile water in the drinking spoon 74.

[0044] The implementation principle of an automatic drinking water device for experimental animals in an embodiment of the present application is as follows: when the liquid level in the water tank 2 continues to drop and triggers the liquid level sensor 83 at the bottom of the water tank 2, the liquid level sensor 83 feeds back information to the control system, and the control system starts the water supply pump 82. The water supply pump 82 pumps the water in the water dispenser into the water tank 2 through the water inlet pipe 81, causing the liquid level in the water tank 2 to rise and trigger the liquid level sensor 83 at the top of the water tank 2. At this time, the control system controls the water supply pump 82 to stop working.

[0045] When the liquid level sensor 83 at the bottom of the water tank 2 is triggered and the liquid level does not change for a long time, the control system activates the alarm 14, and the alarm 14 sounds an alarm to remind the experimenter to replenish water. The sterile water in the water tank 2 flows to each drinking nozzle 7 through the main water pipe 3 and the branch pipe 6, and the animals in the breeding box 5 can automatically replenish water through the drinking nozzle 7.

[0046] The animals in the feeding box 5 press the drinking spoon 74, and the drinking spoon 74 drives the drinking rod 73 to rotate around the rotating shaft 72. The compression spring 762 is forced to contract, so that the drinking trough 75 on the drinking rod 73 is separated from the flow-stop protrusion 761, and the water in the drinking pipe 71 can flow out through the drinking trough 75 on the drinking rod 73 and flow into the drinking spoon 74. The drinking spoon 74 continues to rotate under the pressure of the animals until the drinking spoon 74 stops rotating. At this time, the drinking rod 73 will pull the float 11 through the pull rope 12, and the float 11 will drop and block the inner diameter of the drinking pipe 71.

[0047] During this process, the leak-proof rubber block 13 continuously deforms to block the gap between the drinking water pipe 71 and the drinking water rod 73. When the animal stops pressing, the compression spring 762 recovers its deformation and pushes the drinking water rod 73 to reset. The drinking trough 75 on the drinking water rod 73 is pressed against the flow-stop protrusion 761 again, and the sterile water in the drinking water pipe 71 is never prevented from continuing to flow. The animal can drink the sterile water in the drinking spoon 74.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
