Description

[Detailed description of the invention] This invention relates to the improvement of an automatic water supply device that is attached to a container for raising small animals such as mice and rats. This is intended to prevent water from accumulating inside the container by discharging water leaking from the drinking vessel outside the breeding container.

The present invention will be explained with reference to the drawings. The drawings show an embodiment in which an automatic water drinking device 2 is inserted horizontally into a cage 1 for raising small animals such as mice and rats.

The water drinking device 2 has a rubber cylinder body 8 having a T-shaped disk portion 7 at the center of a water reservoir chamber 6 formed by a body 3 of the water reservoir and a lid body 5 having a water supply port 4 screwed into the body. A drinking capillary 10 having an umbrella-shaped head 9 in cross-section is inserted. 11 is water drinking tube 1
0, its base side 12 is screwed to the inner peripheral wall 13 on the bottom side of the body 3, and the water drinking capillary tube 10
The distal end 15 of the protective outer tube can be adjusted in and out of the distal end 14 of the protective outer tube. The rubber cylindrical body 8 holding the water drinking tube has a T-shaped disc portion 7.
The inner bottom surface 16 of the body 3 and the screw end surface 17 of the lid body 5
When a small animal such as a mouse or a rat moves the tip 14 of the drinking tubule with its snout, the umbrella-shaped head 9 at the end of the drinking tubule and the rubber cylinder 8 are separated. A gap is created between the contact with the disc 7, and through the gap water in the body enters the drinking tube and reaches its tip, allowing the small animal to drink water from the tip opening. This water drinking tube is used by small animals to supply water by moving its tip with their snout, so when drinking water,
Alternatively, if a small animal moves the tip of the drinking tube with its hands or feet, water leaks into the breeding container, contaminating the inside of the container, and causing adverse effects on breeding.

In view of these drawbacks, the present invention has a gutter-like receiver 18 attached to the outer tube 11 that protects the water-drinking tube so as to be inclined downward from the tip of the water-drinking tube toward the body, thereby preventing water from flowing from the tip of the water-drinking tube. This system allows leakage water to be discharged to the outside of the breeding container.

As described above, the present invention uses an automatic water drinking device in which a small animal can drink water supplied from the central tubule by moving the central tubule of the drinking device with the tip of the mouth. Even if a gutter-shaped water leakage receiver is attached to the protective tube, this gutter-shaped water leakage receiver does not cause any problem for small animals to drink water, and this gutter-shaped water leakage receiver is installed close to the small drinking bowl. Therefore, the overall external size of the water bowl is small, and the water supply window on the breeding cage side into which it is inserted can also be small.When the water bowl is removed, small animals can be prevented from escaping from the cage water supply window. If you place a water container that accepts water leakage on the side of the small animal breeding shelf, you can easily insert or remove the water container from the water supply port of the cage when you frequently take out and put cages in small animal experiments. It can be connected to and detached from the cage, and water leaking from the water bowl can be drained out of the cage using the gutter-like receiver that is integrally attached to it, so it has great practical effects when raising small experimental animals such as mice and rats. It is what it is.

Claims (1)

[Scope of utility model registration request] In the center of the water reservoir body 3, there is a protective outer pipe 11 on the outside.
A water drinking tube 10 having a diameter of 10 mm is held by a T-shaped rubber cylinder 8 and installed, and when a small animal such as a mouse or a rat moves the tip of the water drinking tube 10 with its snout, it is removed from the body of the water reservoir. In a drinking device that supplies water to the tip of the drinking tube through the drinking tube, the protective outer tube 11 receives water leaking from the tip of the drinking tube.
A water drinking device for rearing mice, rats, etc., characterized in that a gutter-like receptor 18 is attached to discharge water to the outside of the rearing container.
