Description

Technical Field

[0001] The utility model relates to the technical field of sugar water preference experiments, and specifically relates to a water intake device for mice in sugar water preference experiments. Background Technique

[0002] ‌The sugar water preference experiment‌ is a commonly used test method in animal behavior research, especially for studying the emotional states of rodents such as mice, such as anhedonia and depression. This experiment utilizes the natural preference of animals for sweetness to evaluate their emotional and mental health states. Its basic principle is also based on the innate preference of rodents for sweet foods;

[0003] In the experiment, generally two drinking devices are provided, one filled with sucrose solution and the other filled with ordinary water, and the mice are allowed to choose freely. Under normal circumstances, healthy and psychologically well animals will show a significant preference for sweetness (such as sucrose solution). This preference reflects the function of the animal's reward system, mainly the dopamine pathway in the brain. Therefore, in this experiment, the water intake device is particularly important. Therefore, during the working process, a corresponding water intake device needs to be used. In order to facilitate the mice to drink water, it is usually necessary to assemble it on the railing of the mouse cage. Therefore, if the assembly or subsequent water addition is inconvenient, it will easily bring inconvenience to the experimental assembly. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water intake device for mice in sugar water preference experiments, so as to solve the problem proposed in the above background technique that a corresponding water intake device needs to be used during the working process. In order to facilitate the mice to drink water, it is usually necessary to assemble it on the railing of the mouse cage. Therefore, if the assembly or subsequent water addition is inconvenient, it will easily bring inconvenience to the experimental assembly.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water intake device for mice in sugar water preference experiments, including a quantitative drinking bottle, a mouse cage railing, and a feeding water pipe. A scale line is fixed on the front end face of the quantitative drinking bottle. A connecting rod is fixed on the side of the quantitative drinking bottle. Two sets of connecting seats are assembled on the side of the connecting rod. An installation ring is rotatably connected inside the connecting seat. An installation bolt is connected inside one of the installation rings. A protective pad is adhesively connected to the inner wall of the other installation ring. A first thread groove is opened inside the top of the quantitative drinking bottle. A first connecting block is connected inside the first thread groove. A first limiting plate is fixed at the top of the first connecting block. A water injection hole is assembled at the top of the first limiting plate.

[0006] Preferably, a sealing plug is assembled inside the top of the water injection hole. A threaded connection is formed between the first connecting block and the first thread groove.

[0007] Preferably, two groups of the connecting rods are installed at the side position of the quantitative drinking bottle, and the mounting rings are symmetrically distributed about the central axis of the connecting rod.

[0008] Preferably, a threaded lock is formed between the mounting ring and the mounting bolt. A threaded groove hole is provided in the cage railing, and the tail end of the mounting bolt extends to the position of the threaded groove hole for connection and assembly.

[0009] Preferably, the bottom of the quantitative drinking bottle is connected with a docking cylinder. A second connecting block is connected inside the docking cylinder. A second limiting plate is installed at the bottom end of the second connecting block. A connecting head is installed at the bottom end of the second limiting plate. The bottom inside of the connecting head is connected with a feeding pipe.

[0010] Preferably, a tightening end is provided at the tail end inside the feeding pipe. A rolling ball is assembled inside the tail end of the feeding pipe, and the diameter of the rolling ball is larger than that of the tightening end.

[0011] Preferably, a heat preservation cloth is connected to the outside of the feeding pipe. An insertion port is installed at a position above the side of the heat preservation cloth. Heat preservation cotton is filled inside the heat preservation cloth, and a heating resistor is assembled inside the heat preservation cloth.

[0012] Preferably, a first magic tape is installed on the end face of one end of the heat preservation cloth, and a second magic tape is installed on the end face of the other end of the heat preservation cloth. A bonding connection is formed between the first magic tape and the second magic tape.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The mouse water intake device for the sugar water preference experiment not only improves the assembly ability, but also improves the heat preservation ability and licking ability of the mouse water intake device;

[0014] (1) By fixing the connecting rod at the side position of the quantitative drinking bottle, and a connecting seat is assembled on the side of the connecting rod. The connection and installation with the mounting ring are completed by rotating the shaft rod inside the connecting seat. Then the mounting ring is adjusted to hoop outside the cage railing. After adjusting its assembly height, the connection and fixation between the mounting ring and the cage railing are completed by using the mounting bolt at the position of the mounting ring. At the same time, a first threaded groove is provided inside the top of the scale line. The cooperation connection between the first connecting block and the first threaded groove is completed by rotating the first limiting plate, so as to facilitate the addition of water source inside the scale line.

[0015] (2) By connecting the heat preservation cloth to the outside position of the feeding pipe. At this time, after the first magic tape and the second magic tape are adhesively assembled with each other, the heat preservation cloth is wrapped outside the feeding pipe. After wiring at the position of the insertion port, the heating resistor is energized and heated at its position, and at the same time, heat preservation treatment is carried out by the heat preservation cotton, so as to improve the overall heat preservation ability during water intake;

[0016] (3) The water intake facility for the mice is through this water supply pipe. Therefore, when the mice lick to take water, they will lick the end position of this water supply pipe. A rolling ball is assembled inside the end of this water supply pipe. Therefore, when the mice lick, the rolling ball moves inward. At this time, the gap between the rolling ball and the water supply pipe gradually increases, causing the rolling ball to leave the tightening end position. After the gap is generated, water gradually flows out, thereby better improving the overall licking ability during the working process. Brief Description of the Drawings

[0024] A sealing plug is assembled inside the top of the water injection hole 5. A threaded connection is formed between the first connecting block 3 and the first thread groove 6.

[0025] Two sets of connecting rods 7 are installed on the side of the quantitative water bottle 1. The installation rings 9 are symmetrically distributed about the central axis of the connecting rod 7.

[0031] Based on the sugar water preference experiment, two quantitative water bottles 1 need to be assembled. One is 1% sucrose water and the other is drinking water. The mice need to be raised individually in cages and fed freely;

When the mouse licks to get water, it will lick the tail end position of the water feeding pipe 12, and a rolling ball 21 is assembled inside the tail end of the water feeding pipe 12. Therefore, when the mouse licks, the rolling ball 21 moves inward. At this time, the gap between the rolling ball 21 and the water feeding pipe 12 gradually increases, causing the rolling ball 21 to leave the tightening end 22 position, and water gradually flows out after the gap is generated. Then, the drinking water volume data can be obtained based on the scale of the scale line 2.
