Abstract

The utility model discloses a single-ventilating and air exchanging cage box which is characterized in that two ventilating pipes are arranged on a box cover or a box body, a filter with a filter membrane is arranged on each ventilating pipe, and the connecting point of the box cover and the box body is provided with a sealing gasket. When the utility model is used, fresh and clean air filtered through the filter membranes can enter the single-ventilating and air exchanging cage box, dirty air containing NH3 and CO2 in the utility model is discharged from an air outlet filter through an air sucking machine, therefore, cage boxes can not generate mutual infection so as to improve the operators' working environment; meanwhile, the utility model also prevents people and animal from generating cross infection, largely simplifies a controlling device and saves investment and running expense.

Description

Terminal purifies monomer ventilation cage box

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

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, be seated in the grid in the box body, be seated in the lid on the box body, it is characterized in that: on lid or box body, be provided with two ventilation ducts, the filter that has filter membrane all is installed on each ventilation duct, is provided with sealing gasket in the junction of box body and lid.

The utility model is owing to be provided with two ventilation ducts on lid or box body, the filter that has filter membrane all is installed on each ventilation duct, one is air intake filter, another is for going out air filter, filtered fresh pure air can enter in the cage box, the stale air that contains NH3 and CO2 in the cage box is discharged from going out air filter, can not produce mutual infection between each cage box, stale gas in the cage box of discharging from go out air filter 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, improved operating personnel's working environment, also prevented simultaneously that people and animal from producing the possibility of cross-infection, also simplified 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 filter structure schematic representation on the lid among Fig. 2

Fig. 4 is for being contained in another filter structure schematic 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 12 in the box body 1, in grid, can be divided into drinking area 13, the feed district 14 of animal, on box body 1, put lid 2 is arranged, it is different from prior art and is: be provided with two ventilation ducts 3 on lid 2 or box body 1, present embodiment is provided with two ventilation ducts 3 on lid 2, the filter 5 that has filter membrane all is installed on two ventilation ducts 3, one of them is air intake filter for a filter 5 in the enforcement on two ventilation ducts 3, another is for going out wind filter, their end opening, other end sealing; The filter 5 that has filter membrane in an embodiment has the shell 6 of a mesh, filter membrane 7 is fixed in the shell 6, the filter 5 that perhaps has filter membrane has the shell 6 and the inner casing 8 of a mesh, filter membrane 7 is fixed between the inside and outside shell, 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, the air intake filter 5 of present embodiment has the shell 6 of a mesh, filter membrane 7 is fixed in the shell 6, going out wind filter 5 has the shell 6 and the inner casing 8 of a mesh, filter membrane 7 is fixed between the inside and outside shell, in an embodiment ventilation duct 3 is fixed on the lid 2 by nut 9, cover is loaded onto filter 5 on ventilation duct 3, in order to make the effect that purifies air better, the dimensions length of air intake filter will be longer than out air filter, in order to increase sealing, with the junction of ventilation duct 3 sealing gasket 4 is housed at lid 2 or box body 1, also be provided with in the junction of box body 1 and lid 2 sealing gasket 4 ', in order to strengthen the ventilation effect in the cage box, on lid 2, be provided with division board 10, 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 11 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.
