When clean gas is imported into the independent ventilating cage, the clean gas blown into the independent ventilating cage from the ventilating cavity can spread all around when meeting the surface of the base, an airflow surface can be formed at the inner part of a box body and can be propelled forwards, a gas exchanging dead zone can be prevented from being formed at the front part of the box body, and the purpose of complete gas exchange can be reached.
Description
Technical field
The utility model belongs to raising and the experimental facilities of a kind of laboratory animal, relates in particular to a kind of valve of independent ventilation cage.
Background technology
According to statistics, life science accounts for 60% about zooperal problem, is the important support condition of life science, and a lot of great scientific achievements all obtain by zoopery in history.Prove that by zoopery the source of infection of human many communicable diseases is various microorganisms, as the plague, brucellosis, diphtheria, tetanus, smallpox etc.These scientific achievements have been determined the relation of various pathogenic microorganismss and human diseases to make the various infectious diseases of prevent disease, epidemic prevention and treatment become possibility.
For guaranteeing the accuracy of experimental data, laboratory animal survival environment and condition have specific (special) requirements as animal room, animal facility, ventilation, temperature, humidity, illumination, noise, cage tool, feed, drinking-water and various bedding and padding etc.Independent ventilation cage letting animals feed is mainly adopted in this area at present, each cage of independently ventilating comprises casing and loam cake, loam cake is provided with air inlet and gas outlet, the pressure air that pressure fan is sent, be blown in the casing through air inlet, waste gas in the cage is discharged through exhaust outlet, reaches the replacing fresh air, the purpose of carbonic acid gas and ammonia nitrogen concentration in the reduction cage.
Yet the air inlet of existing domestic ventilation cage mostly is a straight tube, and air flows to the rear that directly rushes at casing behind the ventilation cage casing, forms the dead band easily in the place ahead of casing, can not reach the purpose of thorough ventilation.
The utility model content
In view of this, the technical problem that the present invention will solve provides a kind of valve of independent ventilation cage, has the thorough phenomenon of dead band ventilation that occurs when the ventilation cage is taken a breath now to solve, and reaches the purpose of thorough ventilation.
For realizing above-mentioned technique effect, the utility model provides a kind of valve of independent ventilation cage, comprising:
Joint with air inlet and gas outlet;
Venting cavity with air inlet and gas outlet, the air inlet of venting cavity docks with the gas outlet of joint;
The base that the surface is relative with the gas outlet of venting cavity;
Gripper shoe connects base and venting cavity.
Preferred embodiment, the gas outlet that described gripper shoe one end connects venting cavity and separates described venting cavity, the other end of described gripper shoe connects and separates base.
Preferred embodiment, the air inlet of described joint is contracted to the gas outlet gradually.
Preferred embodiment, the surface of described base is provided with baffle plate, and described baffle plate one side tilts to gripper shoe.
Preferred embodiment, described baffle plate be shaped as arch.
The valve of the independent ventilation cage that the utility model provides, bag has the joint of air inlet and gas outlet; Venting cavity with air inlet and gas outlet, the air inlet of venting cavity docks with the gas outlet of joint; The base that the surface is relative with the gas outlet of venting cavity; Gripper shoe connects base and venting cavity.When input in ventilation cage during clean gas, the surface that the gas that is blown into from venting cavity is met base to around diffusion, form an air-flow towards preceding propelling at box house, avoid forming the ventilation dead band in casing the place ahead, reach the purpose completely of taking a breath.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the front view of first embodiment of the valve of independent ventilation cage described in the utility model;
Fig. 2 is the end view of the valve of independent ventilation cage shown in Figure 1;
Fig. 3 is the front view of second embodiment of the valve of independent ventilation cage described in the utility model;
Fig. 4 is the end view of the valve of independent ventilation cage shown in Figure 3;
Fig. 5 is the stereogram of the valve of independent ventilation cage shown in Figure 3.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The structural representation of the valve of independent ventilation cage described in the utility model is with reference to figure 1 and Fig. 2, and valve comprises: joint 11, venting cavity 12, gripper shoe 13 and base 14.Dock with the air inlet of venting cavity 12 gas outlet of joint 11, and gripper shoe 13 1 ends connect the gas outlet of venting cavity 12, and the other end of gripper shoe 13 connects the surface of base 14.In the present embodiment, adopt a gripper shoe, this gripper shoe one end is cut apart the gas outlet of venting cavity 12, the other end is cut apart the surface of base 14, and when gas blew out from the gas outlet of venting cavity 12, the supported plate 13 of gas was divided into the surface that two parts blow to base 14 respectively, gas is met the surface of base 13 to diffusion all around, form an air-flow towards preceding propelling at box house, avoid forming the ventilation dead band in casing the place ahead, reach the purpose completely of taking a breath.
In the utility model another one embodiment, as Fig. 3,4 and shown in Figure 5, the quantity of gripper shoe is four, four gripper shoes are vertical mutually, the surface of base 14 is provided with baffle plate 31, and baffle plate 31 tilts to adjacent gripper shoe 131, gripper shoe 132, and connects gripper shoe 131, gripper shoe 132.Gas impacts base 14 along baffle plate 31, is convenient to gas and spreads uniformly around base, prevents that gas from directly impacting base, shines into backflow.Need to prove that according to no design requirement, baffle plate can be designed to arbitrary shape, the every effect that can play water conservancy diversion all belongs to the protection domain of technical solutions of the utility model, and baffle plate is shaped as arch in the present embodiment.
