Abstract

An independent wind supply purifying little mouse cage mainly solves the problems of complicated technology of barrier environment, long working period, high costs, unsuitability for wide use, inconvenience of use and maintenance and inability of moving. The utility model comprises a rack and a mouse box. The utility model is characterized in that: the rack is provided with a multilayered belt wind supply hole and a mouse box of the wind discharge filtering lid. The end of the rack is provided with a wind supply main tube and a wind discharge main tube. One end of the wind supply tube and that of the wind discharge tube are respectively connected with the wind supply device and the wind discharge device. The rack is provided with the wind supply branch tube and the wind discharge branch tube which are connected with mouse boxes of each layer. The advantages are that: the self-bring wind supply and discharge device is compact in structure, small in occupied area, simple in manufacture technology, reliable in operation, can adjust the wind amount according to the experimented animals, convenient in use and maintenance, can move conveniently and flexibly, has the service life of more than ten years and low noise, has the lower price than that of the building construction costs and the foreign similar products.

Description

Independent air-supply purifies the mouse cage

Technical field

The utility model belongs to a kind of laboratory animal and raises facility, and particularly a kind of independent air-supply purifies the mouse cage.

Background technology

Needs for subject experimental studies such as medical science, pharmacology, biotechnologys, some scientific researches, production and teaching unit all will use a great deal of satisfactory laboratory animal every year, national Specification, China's laboratory animal environment is divided into three kinds of regular grade, barrier level and isolation levels, wherein regular grade can not be controlled infectious agent, is suitable for raising the common laboratory animal of purposes such as teaching.And barrier environment is because the turnover of strict control personnel, article and surrounding air is applicable to and raises clean animal and no-special pathogen (SPF) laboratory animal that require than higher, application is many.It is the highest that isolation environment requires, and normally adopts isolators such as isolator to realize local isolation environment.China realizes that at present the main mode of barrier ring mirror is to adopt the building means, air cleaning and conditioning system is installed, do the technology complexity like this, long in time limit, the cost height, the complexity of operation maintenance simultaneously can not be according to using needs to move, be unfavorable for the barrier environment extensive use, particularly the unit that most of small-scales are raised is all the more so.

The utility model content

The purpose of this utility model provides a kind of independent air-supply and purifies the mouse cage, compact conformation, and technology is simple, and floor space is little, and is reliable, and working service is easy, and what energy was convenient, flexible moves, long service life, price is low.

The purpose of this utility model is achieved by the following technical solution: it comprises frame, the mouse box, it is characterized in that: the mouse box of placement of multiple layers band wind pushing hole and air draft filtering cover on frame, the blast main is housed in the end of frame and air draft is responsible for, an end of send, air draft being responsible for connects air-supply arrangement and air exhausting device respectively, assembling and supporting blowpipe that is connected of each layer mouse box and air draft arm on frame.

The air draft filtering cover of above-mentioned mouse box is made of following efficient filter paper and top orifice plate, the top assembling exhaust hood of orifice plate.

The wind pushing hole place assembling air-supply valve of above-mentioned mouse box, blowpipe connects the air-supply conduit, assembles sliding guide sleeve on the air-supply conduit, affixed seal on the sliding guide sleeve, sliding seal one end is provided with stage clip, and the part that the air-supply conduit inserts mouse box valve is provided with the air-supply side opening.

The utility model has the advantages that: carry the supply and exhaust device, compact conformation, floor space is little, and manufacture craft is simple, and is reliable, can be according to the air quantity of how much adjusting of laboratory animal, working service is easy, and can be convenient, flexible move used more than 10 years, noise is low, and price is far below the cost of construction techniques and the price of external like product.

Fig. 4 is that the air-supply valve of mouse box connects schematic diagram with blowpipe.

Embodiment

See Fig. 1-4, concrete structure is as follows: the transparent mouse box 3 that placement of multiple layers is arranged on the stainless steel frame 2 of foot wheel 9.Fixing assembling barrier 13 is placed water bottle 15 and feed in the mouse box 3 on the barrier 13.Assembling air draft filtering cover 10 on the mouse box 3, the following of air draft filtering cover 10 is the filter paper of filtered air, is orifice plate 11 above, the top assembling exhaust hood 12 of orifice plate 11.Blast main 8 is housed at the two ends of frame 2 and air draft is responsible for 1, and the upper end of send, air draft being responsible for is the air-supply arrangement 5 and the air exhausting device 4 of connecting band filter respectively, and air-supply arrangement 5 and air exhausting device 4 all adopt prior art.Assembling and each layer mouse box 3 supporting blowpipe that is connected 7 and air draft arms 6 on frame 2, each layer blowpipe 7 be connected respectively with air draft arm 6 give, the air draft person in charge 8,1.The structure that mouse box 3 connects blowpipe 7, air draft arm 6 is: the air draft conduit that air draft arm 6 connects directly is inserted in the mouse box exhaust hood 12.At the guard shield 14 of the wind pushing hole inboard of mouse box 3 fixed band fresh air inlet, connect check valves 16 by rotating shaft and torsion spring 17 in the guard shield 14.Wind pushing hole periphery at mouse box 3 is provided with closure gasket groove.Wind conduit 21 picked in blowpipe 7 first line of a couplet, assembling sliding guide sleeve 19 on the air-supply conduit 21, and affixed lip ring 20 on the sliding guide sleeve 19, lip ring 20 1 ends are provided with stage clip 18, and the part that air-supply conduit 21 inserts mouse box valve is provided with air-supply side opening 22.During from frame 2 taking-up mouse boxes 3, mouse box valve 16 and air-supply conduit side opening 22 are closed automatically; When putting back to mouse box 3, air-supply conduit 21 inserts mouse box valve 16 and gets final product, and realizes independent air-supply and air draft.

The course of work: the utility model belongs to the forced draft system, room air enters air-supply arrangement 5 and enter blast main 8, arm 7 by blower fan after high efficiency particulate air filter filters, enter each mouse box 3 again, air overflows into exhaust hood 12 via air draft filtering cover 10 in the box, and be inhaled into exhaust branch pipe 6 with the part room air, be responsible for 1, discharge from the air exhausting device 4 of band filtering and purifying at last.Promptly guaranteed the cleanliness factor of air-supply, made the unlikely pollution indoor-outdoor air of air of discharge again.
