Description

Technical Field

[0001] The utility model relates to the technical field of laboratory mouse feed feeders, in particular to an anti-blocking feeder for laboratory mouse fluid feed. Background Art

[0002] Fluid feed for laboratory mice is a kind of animal feed commonly used in clinical and medical experiments. The feeding / watering bottles for laboratory mice currently available on the market are very likely to cause blockage of the feeding bottle mouth due to the long-term static sedimentation of the fluid feed when feeding the laboratory mice with fluid feed, resulting in poor or even impossible flow of the fluid feed, which in turn leads to insufficient nutritional intake of the laboratory mice, causing malnutrition or even death of the laboratory mice, affecting the results of clinical and medical experiments and increasing the cost of the experiment. In addition, under certain experimental conditions and special environmental conditions, the existing fluid feed feeding devices (such as fluid feed high cage feeding devices) are too complicated in structure and inconvenient for the laboratory mice to eat, resulting in the inability to achieve the experimental purpose.

[0003] In summary, how to provide a fluid feed feeding device for experimental mice that can prevent fluid feed from being blocked is a technical problem that needs to be solved urgently in the art. Utility Model Content

[0004] The utility model provides an anti-blocking feeder for fluid feed of experimental mice, so as to solve the technical problem that the fluid feed in the experimental mouse feeder in the prior art is easy to be blocked.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is:

[0011] When the experimental mouse repeatedly lifts the experimental mouse top piece from under the feeding port, it drives the blocking piece to rise and open the feeding port to allow the fluid feed stored in the internal accommodating space to flow out, and at the same time drives the spiral wire to stir and loosen the fluid feed in the internal accommodating space and the feed flow channel.

[0012] Preferably, the top piece of the experimental mouse is hemispherical.

[0013] Preferably, the top seat is cylindrical.

[0014] Preferably, an annular flange is provided on the periphery of the lower end of the top seat, and the top seat can be embedded in a cylindrical mounting hole whose shape matches that of the fixture and the top seat, and can be fastened in the cylindrical mounting hole by cooperating between the annular flange and the mounting step at one end of the cylindrical mounting hole.

A spiral wire is inserted through the feed flow channel of the top seat and the internal accommodation space of the feeding tube, and an experimental mouse top piece is arranged at one end of the spiral wire that extends downwardly out of the feeding tube. The experimental mouse, which has been trained for a short time, can repeatedly push up, push and pull the experimental mouse top piece to take food from the feeding tube, while driving the spiral wire to stir and loosen the fluid feed in the feeding tube and the feed flow channel, thereby preventing the fluid feed from easily blocking the feeding port at the lower end of the feeding tube due to long-term static state, causing malnutrition or even death of the experimental mouse.
