Abstract
Description
Technical Field
[0001] This utility model belongs to the field of animal experimental cage technology, specifically relating to a water feeding structure for experimental animal husbandry. Background Technology
[0002] Animal cages are experimental instruments used in the field of biology, typically for housing laboratory mice to provide accurate experimental research data.
[0003] Currently, when laboratory animals drink water, keepers usually pour the drinking water into an empty dish and then place the dish containing the water into the cage. Because the drinking water is exposed to the air for extended periods, it is easily contaminated and spoiled. Furthermore, since the mice frequently move around in their cages, they often spill the water, increasing the frequency of water changes and creating a damp environment in the cages that is particularly prone to bacterial growth, which is detrimental to the normal growth of the mice. Utility Model Content
[0004] This invention provides a water feeding structure for laboratory animals, which solves the problems of existing cages where drinking water is directly exposed to the air, making it susceptible to contamination and deterioration, and easily overturned, leading to bacterial growth.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a water feeding structure for laboratory animals, including a cage, which further includes:
[0006] A water inlet pipe, which is fixed inside the cage;
[0007] A diversion assembly is installed at the bottom of the water inlet pipe and is used to guide water from the water inlet pipe into the cage.
[0008] Optimally, the drainage assembly includes a drainage block detachably installed at the bottom of the water inlet pipe, at least one drainage channel formed within the drainage block and connected to the water inlet pipe, and a locking mechanism installed at the bottom of the drainage block, the locking mechanism being used to open and close the drainage channel.
[0009] Optimally, the drainage assembly further includes a first mounting groove formed on the top of the drainage block and a transition cavity formed between the water inlet pipe and the first mounting groove.
[0010] Optimally, the drainage channel includes a second mounting groove formed at the bottom of the drainage block, a second drainage channel connected to the second mounting groove and extending toward the side near the transition cavity, and a first drainage channel connecting the second drainage channel and the transition cavity.
[0011] Optimally, the locking mechanism includes a locking block installed in the second mounting groove, a tapered portion formed on the side of the locking block away from the second drainage groove, and a stop ball resiliently installed in the locking block.
[0012] Optimally, the locking mechanism further includes a spring disposed in the second drainage groove, one side of the spring abutting against the ball, and the other side of the spring abutting against the side of the second drainage groove near the first drainage groove, wherein the diameter of the second drainage groove is larger than the diameter of the first drainage groove.
[0013] Optimally, it also includes a stop block fixed to the outer circumferential surface of the inlet pipe, which limits the inlet pipe from being screwed into the drain block.
[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0015] This utility model of a water feeding structure for laboratory animals, by setting up a drainage component, can direct the water from the inlet pipe to the drainage trough of the drainage block. The drainage trough is opened and closed by a locking mechanism. The concealed drinking water design can avoid the problem of water source being exposed to the air for a long time and becoming contaminated and deteriorated. It can also prevent the problem of bacteria growing in the cage due to dampness caused by the water bowl being overturned. Moreover, it can meet the drinking needs of multiple laboratory mice at the same time. Attached Figure Description

[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0023] like Figure 1The diagram shown is a cross-sectional view of the water feeding structure for laboratory animals according to this utility model. The concealed drinking water design can prevent the water source from being exposed to the air for a long time and thus avoid pollution and deterioration. It can also prevent the water bowl from being overturned and causing bacteria to grow in the cage due to dampness, which is conducive to the normal growth of laboratory mice in the cage.
[0024] This water feeding structure is typically installed inside animal cages to provide drinking water for the animals (usually laboratory mice) kept in the cages. The structure includes a water inlet pipe 1 and a drainage component. The water inlet pipe 1 is fixedly installed at the top of the cage and extends into the cage. The drainage component is installed at the bottom of the water inlet pipe 1 to guide the water flow from the inlet pipe 1 into the cage. This allows multiple laboratory mice to drink simultaneously, avoiding the situation in existing technologies where only one water bowl is placed, which can lead to mice fighting and knocking over the water bowl.
[0025] The water inlet pipe 1 is fixed to the top of the cage and extends into the cage. Specifically, the cage is a metal cage frame, and the top of the cage has a through hole for the water inlet pipe 1 to pass through. The water inlet pipe 1 passes through the through hole at the top of the cage from bottom to top, and is then fixed to the cage by welding. The top of the water inlet pipe 1 is higher than the upper surface of the cage, making it convenient for the keepers to add water to the water inlet pipe 1 (after the keepers add water to the water inlet pipe 1, they use a rubber stopper to cover the top of the water inlet pipe 1 to prevent the water source from being exposed and contaminated).
[0026] The stop block 2 is integrally connected to the outer circumference of the water inlet pipe 1. It is used to limit the water inlet pipe 1 when screwed into the drain block 3, so as to prevent the water inlet pipe 1 from being screwed in too deeply and blocking the first drainage groove 7 (the water inlet pipe 1 passes through the through hole at the top of the cage from bottom to top, which can avoid installation interference between the stop block 2 and the through hole of the cage. The depth of the water inlet pipe 1 through the cage can be adjusted appropriately according to the size of the cage).
[0027] like Figure 3 The diagram shows a cross-sectional view of the diversion block 3. A first mounting groove 4 is formed on the top of the diversion block 3. The inner circumferential surface of the first mounting groove 4 has an internal thread, and the outer circumferential surface of the water inlet pipe 1 has a matching external thread. The diversion block 3 is screwed to the bottom of the water inlet pipe 1 by twisting. During twisting, the diversion block 3 is tightened when it reaches the bottom of the stop block 2. At this point, a transition cavity 5 is formed between the water inlet pipe 1 and the first mounting groove 4, and the water in the water inlet pipe 1 flows through the transition cavity 5 to the surrounding drainage channels.
[0028] Since the inlet pipe 1 and the drain block 3 are connected by threads, they can provide a certain degree of sealing, preventing water in the inlet pipe 1 from overflowing between the inlet pipe 1 and the drain block 3. At the same time, when the drain block 3 is screwed to the bottom of the inlet pipe 1, the drain block 3 contacts the stop block 2, and the surface contact between the two can also provide a certain degree of sealing (therefore, the stop block 2 has two functions: one is to stop and limit the screwed-in drain block 3 to ensure that a transition cavity 5 is formed between the inlet pipe 1 and the first mounting groove 4; the other is to form a secondary seal with the drain block 3 to prevent water in the inlet pipe 1 from overflowing and leaking).
[0029] There is at least one drainage trough, which is opened in the drainage block 3 and connected to the transition cavity 5. The water in the water inlet pipe 1 flows to the locking mechanism through the transition cavity 5 and the drainage trough (the drainage trough is arranged around the periphery of the drainage block 3, which can provide water for multiple experimental mice at the same time, avoiding the situation in the prior art where only one water bowl is placed, which leads to the experimental mice fighting and knocking over the water bowl. In this embodiment, the drainage trough ring is provided with six troughs).
[0030] The drainage channel includes a second mounting groove 6, a second drainage channel 8, and a first drainage channel 7, such as Figure 1-3 As shown, the second mounting groove 6 is located on the outside of the diversion block 3, and the second mounting groove 6 is used to install the locking mechanism. The second drainage groove 8 is located inside the diversion block 3 and is connected to the second mounting groove 6. The first drainage groove 7 is located inside the diversion block 3 and is connected to the second drainage groove 8 and the first mounting groove 4 (when drinking water, the water in the water inlet pipe 1 flows into the locking mechanism through the transition cavity 5, the first drainage groove 7, and the second drainage groove 8).
[0031] like Figure 1-3 As shown, the second mounting groove 6, the second drainage groove 8, and the first drainage groove 7 are coaxially arranged, and the diameter of the second drainage groove 8 is larger than the diameter of the first drainage groove 7. Therefore, a shoulder structure is formed between the second drainage groove 8 and the first drainage groove 7 to block the installed spring 9. At the same time, the diameter of the second mounting groove 6 is larger than the diameter of the second drainage groove 8, which blocks the installed locking block 10 to avoid affecting the normal movement trajectory of the ball 13.
[0032] like Figure 3 As shown, the first drainage groove 7 is connected to the bottom of the first mounting groove 4 to ensure that the water in the transition cavity 5 can flow into the drainage groove and avoid water accumulation.
[0033] like Figure 1 , 2As shown in Figure 4, the locking mechanism is installed in the second mounting slot 6 to open and close the drainage trough, facilitating drinking for the laboratory mice in the cage. The locking mechanism includes a spring 9, a locking block 10, a third drainage trough 11, a conical part 12, and a stop ball 13. The outer circumferential surface of the locking block 10 is provided with external threads, and the inner circumferential surface of the second mounting slot 6 is provided with internal threads that mate with it. The locking block 10 is installed in the second mounting slot 6 by screwing (a hexagonal bolt slot is provided on the side of the locking block 10 away from the second drainage trough 8, making it easy to screw the locking block 10 into the second mounting slot 6 with a wrench).
[0034] The third drainage groove 11 is located on the side of the locking block 10 near the second drainage groove 8, and the diameter of the third drainage groove 11 is equal to the diameter of the second drainage groove 8, so as to avoid affecting the normal movement of the ball 13. The tapered part 12 is located on the inner side of the locking block 10, and the diameter of the tapered part 12 gradually decreases from the inside to the outside, which plays a role in blocking and limiting the ball 13, preventing the ball 13 from falling out of the locking block 10.
[0035] The ball 13 is installed in the third drainage groove 11 of the locking block 10, and the spring 9 is installed in the second drainage groove 8. One side of the spring 9 abuts against the ball 13, and the other side of the spring 9 abuts against the shoulder position formed by the second drainage groove 8 and the first drainage groove 7.
[0036] When the laboratory mice in the cage drink water, they lick the abutment ball 13 with their tongues, causing the abutment ball 13 to move inward. At this time, a gap is left between the abutment ball 13 and the cone-shaped part 12, and the water in the second drainage trough 8 flows out along the cone-shaped part 12 for the laboratory mice to drink. After the laboratory mice release their tongues, under the reset action of the spring 9, they push the abutment ball 13 back onto the cone-shaped part 12 to seal the cone-shaped part 12, preventing the water in the second drainage trough 8 from leaking out of the cone-shaped part 12 and avoiding the damp environment inside the cage from causing bacteria to grow.
[0037] The diameter of the ball 13 is smaller than the diameter of the second drainage channel 8 to ensure that the water can flow down normally.
[0038] This utility model of a water feeding structure for laboratory animals can guide water from the inlet pipe 1 to the drainage trough of the drainage block 3 by setting a drainage component. The drainage trough is opened and closed by a locking mechanism. The concealed drinking water design can avoid the problem of water source being exposed to the air for a long time and becoming contaminated and deteriorated. It can also prevent the problem of bacteria growing in the cage due to dampness caused by the water bowl being overturned. Moreover, it can meet the drinking needs of multiple laboratory mice at the same time.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
