[0012] In an embodiment, the third through hole has a diameter d, which satisfies the following condition:
[0013]
[0014] wherein η is the viscosity of air, L is the thickness of the second cover body in the vertical direction, Q is the flow rate of the liquid in the first cylinder body, ρ is the density of the liquid in the first cylinder body, g is the acceleration of gravity, H is the height of the liquid surface in the first cylinder body, h1 is the height of the center of the first through hole, and h2 is the size of the liquid surface in the groove body in the vertical direction from the center of the first through hole.

The lack of pleasure refers to the lack of interest in the stimulation of food, sex, etc. The index is used as a core index for evaluating emotional disorder disease models such as a depression mouse model.
[0032] The water bottle in the existing mouse sugar water preference experiment device is divided into two styles of vacuum type and ball type. The vacuum type water bottle has a small hole in the spout part after water is filled in the bottle, and water enters the mouse's mouth when the mouse licks the spout, but water leaks from the spout when the water bottle is bumped by external force or hit by the mouse, and even moving the water bottle will cause water leakage. The ball type is provided with a ball at the spout, and water enters the mouse's mouth along the ball when the mouse licks the ball, but when the water quantity is small, i.e. the water pressure is small, water leaks from the gap between the ball and the spout, thereby affecting the accuracy of the experimental data.
[0033] The utility model discloses a mouse sugar water preference experiment device, which aims to solve the problem of water leakage in the existing mouse sugar water preference experiment device.

[0035] The utility model provides a technical scheme, through setting up the groove body 2 and first through -hole 21, make the liquid that flows can all get the receiving of groove body 2, avoid the occurrence of the phenomenon of leakage. Further, the height of the groove mouth of groove body 2 is higher than the height of first through -hole 21, so that when the liquid level height in groove body 2 gradually is higher than first through -hole 21, the air pressure in first cylinder body 11 gradually reduces, and the height difference of the liquid level of first cylinder body 11 and groove body 2 is also gradually reducing, finally the whole system tends to be stable, and the liquid will not flow any more, and then when the mouse consumes the liquid in groove body 2, the automatic replenishment of the liquid in groove body 2 is realized, and the accuracy of experimental data is further improved. Meanwhile, the design of groove body 2 is more convenient for the mouse to drink, so that the structure is more reasonable.
[0036] It should be noted that the air pressure in the first cylinder body 11 is lower than the air pressure outside the cylinder, so that when the liquid in the first cylinder body 11 flows out to the groove body 2 and the liquid level in the groove body 2 is higher than the first through -hole 21, a stable liquid column will be formed in the first cylinder body 11. The liquid in the groove body 2 can be licked by the mouse.

Specifically, the cross section of the two first barrels 11 is arranged in a semicircular shape, and the second barrel 1 is arranged in a cylindrical shape, and the two oppositely arranged side walls are rectangular side walls of a semicircular cylinder.
[0038] Further, the second barrel 1 is provided with an inverted scale 6 on the barrel wall corresponding to the opposite side wall, for measuring the volume of liquid flowing out of the two first barrels 11. In this way, the scale 6 can identify the volume of liquid in the two first barrels 11 at the same time, so as to directly measure the outflow of liquids of different concentrations, thereby improving the experimental efficiency and increasing the intuitiveness of the device.
[0039] Further, in order to facilitate the injection of liquid into the second barrel 1, the upper end of the second barrel 1 has an opening for communicating the upper ends of the two first barrels 11 with the outside; the mouse sugar water preference experiment device 1000 further comprises a first cover 3, and the first cover 3 is arranged on the opening.
