Abstract

The utility model discloses a single ventilation and air exchanging cage box, which is characterized in that two air exchanging valves are arranged on a box cover or a box body and a sealing pad is arranged at the connecting position between the box body and the box cover. When the utility model is used, filtered fresh clean air can enter the cage box through a pipeline from the air inlet of an air inlet valve and stale air containing NH [3] and CO [2] in the cage box are exhausted from an air outlet valve. Each cage box can not be infected mutually, the working environment of operating staffs is improved, and simultaneously, the possibility of the cross infection between men and animals is prevented. Control devices are simplified, and the investment and running cost is saved.

Description

Monomer ventilation cage box

The utility model relates to the cage box of experimental animal, but specifically a kind of cage box of monomer ventilation.

Quite a few is open type for the cage box of domestic existing feeding experiment animal, the cage box of this uncovered is placed in the glass cabinet, place again in the desinfection chamber of sealing, need carry out strict purified treatment to the whole test Animal House, correspondingly need dispose the huge Animal House purified treatment control appliance of a cover, cost is very expensive, some belongs to the laminar-flow rack raising cupboard, the cage box that is about to uncovered is seated in the raising cupboard of aseptic purification, requirement to Animal House can correspondingly reduce, but isolate relatively poor between the cage box in the raising cupboard, ventilation in its raising cupboard is distributed in Animal House, and the smell is awful to make Animal House, and operating personnel's environment becomes very poor, not only the animal in each cage box may infect mutually in the raising cupboard, even may produce human-animal's cross-infection.

The purpose of this utility model is to provide a kind of monomer ventilation cage box, the air of fresh purification can be sent in this cage box during use, and the interior unpleasant stale air of cage box can be discharged by special pore, can not make animal generation infection mutually in each cage box.

The technical solution of the utility model is achieved in that monomer ventilation cage box, it mainly comprises box body, is seated in the grid in the box body, is seated in the lid on the box body, it is characterized in that: on lid or box body, be provided with two scavenging air valves, be provided with sealing gasket in the junction of box body and lid.

The utility model is owing to be provided with two scavenging air valves on lid or box body, one be intake valve, and another is an air outlet valve, and filtered fresh pure air can enter the cage box by the air inlet of pipeline from intake valve, and the cage box is interior contains NH ₃And CO ₂Stale air discharge from air outlet valve, can not produce mutual infection between each cage box, stale gas in the cage box of discharging from air outlet valve in addition can be sent into treating apparatus by pipeline, discharge treated gas outdoor then, can avoid the phenomenon that the smell is awful in the Animal House, improve operating personnel's working environment, also prevent that people and animal from producing the possibility of cross-infection simultaneously, also simplify control appliance greatly, saved investment and operating cost.

Fig. 2 is an A-A view among Fig. 1

Fig. 3 is for being contained in the scavenging air valve structural representation on the lid among Fig. 2

The utility model will be further described below in conjunction with drawings and Examples.

The utility model mainly comprises box body 1, be seated in the grid 5 in the box body 1, in grid, can be divided into the drinking area 13 of animal, feed district 14, on box body 1, put lid 2 is arranged, it is different from prior art and is: be provided with two scavenging air valves 3 on lid 2 or box body 1, present embodiment is provided with two scavenging air valves 3 on lid 2, two one of scavenging air valves are intake valve, another is an air outlet valve, the structure of intake valve is all identical with the structure of air outlet valve in force, their concrete structure is, one valve pocket 6 is sleeved on the valve seat 7, packing ring 15 is equipped with in one end of valve pocket 6 and the junction of valve seat 7, back-up ring 10 and spring 8, an end of spring 8 touches valve seat 7 in an embodiment, the other end of spring 8 touches back-up ring 15, one end of packing ring 15 touches back-up ring 10, the other end at valve pocket 6 is equipped with filter membrane 11, the effect of filter membrane is can filter under the situation of gravity-flow ventilation, even have a power failure, animal in the cage box can carry out gravity-flow ventilation in the same old way and take a breath in 10-20 time normal range (NR) per hour, on valve pocket 6, be provided with blow vent 12, on valve seat, adorn a ventilation duct 16, ventilation duct 16 is communicated with blow vent 12 on the valve pocket 6, present embodiment is provided with four blow vents on valve pocket 6, one bonnet 18 is fixedlyed connected with valve seat 7, is provided with air port 22 in bonnet 18; In the lid 2 and the junction of valve seat 7 sealing gasket 19 is housed, with the junction of ventilation duct 16 sealing ring 17 is housed at valve seat 6 near the other end of valve pocket 7, junction at box body and lid is provided with sealing gasket, in order to strengthen the ventilation effect in the cage box, on lid 2, be provided with division board 20, for the ease of moving of cage box, bottom at box body 1 is provided with guide rail, in addition, in order to guarantee the sealing of cage box, be provided with the clamping hasp 21 that matches on box body 1 and lid 2, present embodiment respectively is provided with 2 hasps in the both sides of box body 1 and lid 2 and clamps.

Use of the present utility model is, with the ventilation shaft that purifies air and handle air device respectively with two scavenging air valve disjunctors of cage box, ventilation duct backs down the spring at valve pocket and valve seat place, pure air enters in the cage box by the ventilating opening on the valve pocket, ventilation duct, again through division board, raise the back, district around the contaminated air in the cage box being discharged from air outlet valve to drinking area, the air of discharge after filtration behind the treatment facility discharge outdoor; When intake valve broke away from ventilation duct, valve pocket recovered the position under the effect of spring force, and sealing ring is closed ventilating opening, and this moment, the cage box can only carry out the gravity-flow ventilation ventilation by filter membrane and ventilation duct.
