In order to save space and cost during the use of animal isolation and breeding equipment, multiple animal isolation and breeding equipment are usually connected in parallel to share a ventilation system. However, if the door of one of the animal isolation and breeding equipment is opened separately during use, it will affect the wind pressure changes in other animal isolation and breeding equipment, and may cause the aerosol in the animal isolation and breeding equipment to overflow into the laboratory, causing laboratory environmental pollution, which needs to be improved.

[0020] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are one embodiment of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative work fall within the scope of protection of the present invention.

[0021] Unless otherwise defined, the technical terms or scientific terms used in the present invention should have the ordinary meaning understood by those with ordinary skills in the field to which the present invention belongs.

[0022] This embodiment provides a biosafety negative pressure feeding system for monkeys.

[0023] Refer to Figure 1 、 Figure 2 , a biosafety negative pressure feeding system for monkeys, including a laboratory exhaust device 1, a main exhaust pipe 2 and a plurality of monkey negative pressure feeding cages 3. The main exhaust pipe 2 is connected to the laboratory exhaust device 1, and each monkey negative pressure feeding cage 3 is provided with a separate air supply component 4, an exhaust component 5 and a control component. A plurality of exhaust components 5 are all communicated with the main exhaust pipe 2, that is, a plurality of monkey negative pressure feeding cages 3 are connected in parallel.

[0024] Each monkey negative pressure feeding cage 3 includes an upper negative pressure cabinet 31 and a lower negative pressure cabinet 32, and both the upper negative pressure cabinet 31 and the lower negative pressure cabinet 32 are used for placing monkey cages. The air supply component 4 includes an air supply fan 41, an air supply electric valve 42 and two air supply filter boxes 43. The two air supply filter boxes 43 are respectively communicated with the upper negative pressure cabinet 31 and the lower negative pressure cabinet 32. The air supply fan 41 is connected to the two air supply filter boxes 43 through an air supply pipe 6, and the air supply electric valve 42 is arranged on the air supply pipe 6 and is used to control the communication of the air supply pipe 6.

[0025] The exhaust component 5 includes an exhaust fan 51, a pressure detection sensor 52 and two exhaust filter boxes 53. The two exhaust filter boxes 53 are respectively communicated with the upper negative pressure cabinet 31 and the lower negative pressure cabinet 32. The exhaust fan 51 is connected to the two exhaust filter boxes 53 through an exhaust pipe 7. The pressure detection sensor 52 and the exhaust electric valve 71 are both arranged on the exhaust pipe 7, and the pressure detection sensor 52 is used to detect the air pressure in the exhaust pipe 7.

[0026] Refer to Figure 1 、 Figure 2, an opening and closing sensor is provided on the cage door of each monkey negative pressure breeding cage 3. The opening and closing sensor is correspondingly connected to the control component of the monkey negative pressure breeding cage 3 and is used to detect the opening and closing of the cage door of the monkey negative pressure breeding cage 3. When the cage door of a certain monkey negative pressure breeding cage 3 is opened, the opening and closing sensor transmits the information of the cage door opening to the corresponding control component, and the control component controls the corresponding air supply electric valve 42 to close the air supply pipeline 6 and controls the corresponding exhaust fan 51 to increase the exhaust power, so that air can only enter the upper negative pressure cabinet 31 or the lower negative pressure cabinet 32 through the cabinet door, ensuring the negative pressure environment of the upper negative pressure cabinet 31 or the lower negative pressure cabinet 32 and avoiding the pollution of the laboratory environment caused by the overflow of air flow.

[0027] In order to reduce the air supply area of the cabinet door and increase the air supply flow rate when the cabinet door is opened, a wind baffle 8 is hinged at the top of the cage door of the upper negative pressure cabinet 31 or the lower negative pressure cabinet 32.

[0028] When the cage door of a monkey negative pressure breeding cage 3 is opened, since multiple monkey negative pressure breeding cages 3 are connected to the main exhaust pipe 2, the increase in the power of the exhaust fan 51 of the monkey negative pressure breeding cage 3 with the opened cage door will affect the exhaust of other monkey negative pressure breeding cages 3, resulting in a relative decrease in the negative pressure in other monkey negative pressure breeding cages 3. The pressure detection sensor 52 located in the corresponding exhaust pipe 7 will detect a decrease in the wind pressure in the exhaust pipe 7. At this time, the corresponding control component will control the corresponding exhaust fan 51 to increase the power to ensure normal exhaust, and then ensure the normal negative pressure environment of other monkey negative pressure breeding cages 3. Avoid the spillage of aerosol in the cage.

[0029] Refer to Figure 3 , a flow equalizing plate 431 is provided in each air supply filter box 43 for evenly distributing air flow and improving the air supply efficiency of the air supply fan 41. A return plate 531 is provided in each exhaust filter box 53, and a screen 5311 is provided on the return plate 531 for filtering monkey hair, etc., to improve the service life of the exhaust component 5.

[0030] Refer to Figure 3 , in order to facilitate the disinfection treatment of the monkey negative pressure breeding cage 3, an exhaust electric valve 71 is further provided on the exhaust pipe 7. During the disinfection work, the air supply electric valve 42 and the exhaust electric valve 71 act to close the air supply pipeline 6 and the exhaust pipe 7, making the monkey negative pressure breeding cage 3 in a closed environment and ensuring the disinfection efficiency.

[0031] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
