部１２が突設されている。(Prior Art) A closed experimental animal breeding apparatus has been proposed in Japanese Utility Model Publication No. 46060/1983. To explain this device with reference to FIGS. 7 and 8, the breeding box 1 has a transparent door 4 on the front and is composed of a box body 2 provided with a space 3 in which small animals can be accommodated.
A through hole 7 with an air filter 9 is provided on the surface, and a connecting portion 12 with a small diameter rubber hose 11 that can be connected to the space 3 through a shutoff valve 10 is provided in a protruding manner on the back wall surface 8.

Air pipes 20, 21, 22 are attached which communicate with the rubber hose 11, and the pipes 20 communicate with an air filter 24 and a blower 25 via a line 13. Note that the rubber hose 11 is fixed to an air pipe 22.

む。(Problems to be Solved by the Invention) In the conventional apparatus shown in FIGS. 7 and 8, a connecting portion 12 with a rubber hose 11 having a shutoff valve 10 protruding from the rear surface of the rearing box 1 is provided. To set the breeding box 1 containing small animals on the breeding shelf 14, pull out the rubber hose 11 from the back of the breeding shelf 14 to the front, and attach the breeding box 1 to the end of the rubber hose 11.
The connecting part 12 must be inserted and connected while holding it with the arm, and after the connection, the breeding box 1 is pushed onto the shelf along the guide rails 18 and 19 of the breeding shelf 14.
しかしこの小動物を収容した飼育箱１は重量も
大きく、しかも飼育棚１４に収納したり、取出し
たりする飼育箱１の数は非常に多いため重労働と
なり、特に女性の場合には大変な仕事であつた。 However, the breeding boxes 1 containing these small animals are heavy, and the number of breeding boxes 1 that must be stored in and taken out from the breeding rack 14 is very large, which requires hard labor, especially for women. Ta.

害な微生物が流れ込んでいる。 In this case, in a breeding box housing experimental animals that use harmful microorganisms, air passes through the air filter 9 on the front and flows in through the through hole 7, passes through the back heat cutoff valve 10, and is routed from the rubber hose 11 to the air pipes 22, 21,
20, and is finally sucked in by the blower 25 via the air filter 24. However, since the connecting portion 12 having the cutoff valve 10 was not provided with an air filter, the rubber hose 11, air pipes 20, 2
Harmful microorganisms from small animals in the breeding box 1 flow into the cages 1 and 22.

あるなどの問題があつた。 At this time, when the rearing box 1 is removed from the rearing rack 14, the space 3 of the rearing box 1 is shut off from the outside by the shutoff valve 10, but the tip of the rubber hose 11 remains open to the outside air. In this case as well, since the air in the air pipes 20, 21, 22 is sucked by the blower 25 through the air filter 24, there is a risk that harmful microorganisms may be released into the outside air from the opening at the tip of the rubber hose 11. Although the number of blowers is small, if the blower 2 rubber breaks down or its operation is stopped, there is a risk that harmful microorganisms in the air pipes 20, 21, 22 and the rubber hose 11 will be released into the outside air.

題もあつた。 Furthermore, since the diameter of the shutoff valve 10 attached to the conventional breeding box 1 is very small, and the diameter of the rubber hose 11 is also small, the air in the space 3 of the breeding box 1 is passed through the small diameter path by the blower. 25 and supplying sufficient air to the small animals in the space 3 through the passage hole 7, a blower with a considerably large output is required, which is not only disadvantageous in terms of cost, but also requires a shutoff valve. Therefore, there were problems in this respect as well, such as high costs. Furthermore, there were other problems such as the need for a large-scale air filter 24 in front of the blower 25.

とするものである。 The present invention aims to provide an animal breeding apparatus that can completely solve the above-mentioned conventional problems by attaching a simple air filter to the air outlet on the rear side of the breeding box.

出される危険は全くない。(Function) To set the breeding box containing the animals of the present invention on the pedestal, lift the breeding box and connect the air pipe protruding forward from the back of the pedestal to the air pipe protruding from the back wall of the breeding box. It can be easily set by simply inserting the joint, and as a result, the inside of the rearing box and the air duct of the stand are sealed from the outside air and completely communicated with each other. The air inside the breeding box is sucked in by a blower through the struts and beam members that make up the air duct of the mount, and fresh air passes through the air filter attached to the air hole on the front door of the breeding box. The air that is inhaled and from which harmful microorganisms are removed by an air filter provided on the back wall is discharged to the outside air from a blower through air pipes of the support and beam members of the wall stand. Next, to remove the breeding box from the stand, all you have to do is pull the breeding box forward and remove the pipe joint from the air pipe.There are no harmful microorganisms in the air pipe after the breeding box is removed in this way. There is no risk of these being released into the atmosphere.

ことが可能である。(Effects of the invention) As the present invention is constructed as explained in detail above, the rubber hose is pulled out while holding a heavy breeding box like the conventional equipment, and after connecting the cutoff valve to its tip, the breeding is placed on the breeding rack. There is no need to use equipment such as pushing the box in, and the box can be easily connected to the air pipe connected to the air duct by simply lifting the breeding box, placing it on the stand, and pushing it in. Therefore, even in the case of women, it is possible to set up and take out the rearing box on the stand without having to do much hard work.

ない。 Furthermore, even if animals containing harmful microorganisms are housed in a breeding box, these harmful microorganisms are filtered by the air filter attached to the back wall and do not flow out into the external air duct, so the breeding box can be placed on a rack. When removing it from the air duct, all you have to do is pull it forward and remove it. In this case, even if the suction blower is stopped, there is no risk of harmful microorganisms being discharged from the air duct into the outside air.

能である。 Furthermore, with this invention, there is no need to install a shutoff valve or a large-scale air filter at the front of the suction blower, as is the case with conventional methods. Instead, simply replaceable air filters can be installed on the front and rear surfaces of the rearing box. Because of this, it is possible to reduce costs, and since there is no need to restrict the air passage as in the case of installing a shutoff valve, the capacity of the suction blower can be made smaller compared to conventional devices.
This makes it possible to reduce costs compared to conventional devices.
