Technical Field

[0001] The utility model relates to the technical field of cages, and particularly relates to a novel IVC cage. Background Art

[0002] IVC cages, that is, Individual Ventilated Cages, are devices widely used in multiple fields, especially playing an important role in the breeding of experimental animals and industrial production processes. It not only directly affects the establishment and level of research topics in many fields, but also, with its development, leads research into new realms and promotes the progress of biomedicine.

[0003] For example, an IVC cage for biological experiments disclosed in the patent application with the publication number CN115136899A includes a cage frame and cage boxes; the cage frame is provided with several behavior chambers, biology chambers, and placement chambers for placing cage boxes. An air inlet main pipe, an air outlet main pipe, multiple air inlet branch pipes communicated with the air inlet main pipe, and multiple air outlet branch pipes communicated with the air outlet main pipe are arranged in the cage frame. Each behavior chamber, biology chamber, and placement chamber corresponds to an air inlet branch pipe and an air outlet branch pipe. It also includes a gas generating device, and the gas generating device is communicated with the air inlet branch pipe corresponding to the biology chamber through a gas pipeline, and an adjusting structure is arranged in the gas pipeline. The placement chamber is used for placing cage boxes, the behavior chamber and the biology chamber are used for conducting relevant experiments, the air inlet main pipe and the air outlet main pipe are used for delivering sterilized air to each chamber, and the gas generating device is communicated with the air inlet branch pipe corresponding to the biology chamber through a gas pipeline for conducting relevant gas experiments and delivering air with different gas components to the experimental mice.

[0004] The advantages of the above-mentioned cage are that it can not only provide a breeding space for experimental mice, but also provide an experimental space for experimental mice, greatly saving the space of the laboratory, and not changing the living environment of experimental mice when they are conducting experiments, reducing the influence of other environmental factors on the experiments. However, it still has certain deficiencies: the air supply method of side air supply and exhaust is relatively single, and it is easy to have air flow dead angles inside the cage box; at the same time, the air supply ports and exhaust ports of the cage frame are exposed to the outside for a long time and are extremely easy to be polluted. Summary of the Utility Model

[0005] The utility model provides a novel IVC cage to solve the technical problems that air flow dead angles are likely to appear inside the cage box and the air supply ports and exhaust ports are likely to be polluted in the prior art.

[0006] To solve the above problems, the novel IVC cage provided by the utility model adopts the following technical solutions:

[0007] A novel IVC cage, comprising:

[0008] The placement box has a placement bin inside for placing the cage cover and the cage box. The upper side panel of the placement box has an air supply opening and an air exhaust opening. Inside the air supply opening and the air exhaust opening, there are respectively an air supply component and an air exhaust component that can move up and down. Both the air supply component and the air exhaust component have a working state where they extend into the placement bin and a normal state where they retract into the side panel of the box.

[0009] The cage cover is located between the cage box and the upper side panel of the installation box. The cage cover has an air inlet for docking with the air supply component and an air outlet for docking with the air exhaust component.

[0010] The cage box is used to place the animals to be experimented inside. The bottom of the cage box also has two flow guide seats for converting the incoming air from vertical to horizontal and from horizontal to vertical, so that the incoming air can enter from the air supply opening at the upper end of the placement box and be discharged from the air exhaust opening at the upper end.

[0011] Furthermore, both of the two flow guide seats are arranged obliquely from top to bottom and from the side wall of the cage box to the bottom, and the two flow guide seats are respectively located directly below the air supply opening and the air exhaust opening.

[0012] Furthermore, both of the two flow guide seats are made of silica gel material.

[0013] Furthermore, both the air supply component and the air exhaust component include an iron sheet arranged at the upper part and an air duct connected to the lower end of the iron sheet. Below the iron sheet, there are also annular electromagnets arranged at intervals for the air duct to pass through. The lower ends of the air supply opening and the air exhaust opening both have a converging step, and a baffle is located on the converging step. A return spring that abuts against the baffle and the iron sheet respectively is also sleeved on the air duct.

[0014] Furthermore, both the air inlet and the air outlet have a docking pipe, and the sizes of the docking pipes both meet the requirement for the air duct to be inserted.

[0015] Furthermore, the bottom of the placement box has a pressure sensor for sensing the pressure of the cage box after it is placed and a controller that is signal-connected to the pressure sensor. The controller is control-connected to the annular electromagnet to control the disconnection and attraction between the annular electromagnet and the iron sheet, and further control the air supply component and the air exhaust component to extend into the placement bin or retract into the side panel of the box.

[0016] Furthermore, both sides of the cage box are fixedly connected with a receiving rib for holding.

[0017] Furthermore, there is also a water storage hopper above the stainless steel cage net. A drinking water bottle is placed in the water storage hopper, and there is also a drinking water opening on the side of the water storage hopper for the animals to be experimented to enter and drink water.

[0018] Furthermore, the cage box also has a life window on the side of the water storage hopper that communicates with the outside.

[0019] The beneficial effects of the new type of IVC cage provided by the present utility model are:

[0020] 1) When the cage box is placed into the placement bin, through the induction of the pressure sensor, the controller controls the annular electromagnets in the air supply component and the exhaust component to attract the iron sheets, so that the air ducts at the air supply port and the exhaust port are docked with the docking pipes at the air inlet and the air outlet respectively, and then the air supply starts. In this way, the air supply component and the air inlet component are only docked with the docking pipes during use, which to a certain extent avoids the air supply component and the air inlet component from being polluted by the external environment and reduces the frequency of manual wiping and disinfection;

[0021] 2) The air flow organization form of upper air supply and upper exhaust is adopted inside the cage box, which can effectively avoid air flow short - circuit, and under the action of the flow - guiding seat, the air inside the cage box can circulate more effectively, avoiding the formation of air flow dead - ends;

[0022] 3) The life window is arranged beside the cage box and communicates with the outside world. In the situation of accidental shutdown of the breeding facility, it can absorb the outside air and reduce the possibility of death of the animals to be experimented.

[0023] Through the above settings, the utility model effectively solves the technical problems in the prior art that air flow dead - ends are likely to appear inside the cage box and the air supply port and the exhaust port are easily polluted. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0035] It should be noted that the main idea of ​​the present invention is that when the cage box 8 is placed in the placement bin, the controller 18 controls the annular electromagnet 12 in the air supply assembly 24 and the exhaust assembly 25 to attract the iron sheet 10 through the induction of the pressure sensor 17, so that the air ducts 11 of the air supply port 3 and the exhaust port 4 are docked with the docking pipes 16 of the air inlet 6 and the air outlet 7, and then the air supply is started. In this way, the air supply assembly 24 and the air inlet assembly are only docked with the docking pipes 16 when in use, which to a certain extent avoids the air supply assembly 24 and the air inlet assembly from being polluted by the external environment and reduces the frequency of manual wiping and disinfection; at the same time, the air flow organization form of upper air supply and upper exhaust is adopted inside the cage box 8, which can effectively avoid air flow short circuit, and under the action of the guide seat 9, the air in the cage box 8 can be circulated more effectively to avoid the formation of air flow dead corners; so as to solve the technical problems in the prior art that air flow dead corners are prone to occur inside the cage box 8 and the air supply port 3 and the exhaust port 4 are prone to contamination.

[0036] After introducing the basic principle of the utility model, various non-limiting embodiments of the utility model are specifically introduced below. Any number of elements in the drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0037] The following elaborates on the principles and spirit of the present utility model in detail with reference to several representative embodiments of the present utility model.

[0038] Embodiment of the novel IVC cage provided by the present utility model:

[0039] As Figures 1 to 7 shown, the novel IVC cage includes a placement box 1, a cage cover 5, and a cage box 8. Among them, the placement box 1 has a placement bin inside for placing the cage cover 5 and the cage box 8. The upper side plate 2 of the placement box 1 has an air supply port 3 and an air exhaust port 4. The air supply port 3 and the air exhaust port 4 respectively have an air supply component 24 and an air exhaust component 25 that can move up and down. Both the air supply component 24 and the air exhaust component 25 have a working state extending into the placement bin and a normal state retracted into the side plate 2.

[0040] The cage cover 5 is located between the cage box 8 and the upper side plate 2 of the installation box. The cage cover 5 has an air inlet 6 for docking with the air supply component 24 and an air outlet 7 for docking with the air exhaust component 25; the inside of the cage box 8 is used to place the animals to be experimented on. The bottom of the cage box 8 also has two flow guide seats 9 for converting the incoming air from vertical to horizontal and from horizontal to vertical, so that the incoming air can enter from the air supply port 3 at the upper end of the placement box 1 and be discharged from the upper air exhaust port 4.

[0041] Specifically, the two flow guide seats 9 are both arranged obliquely from top to bottom and from the side wall of the cage box 8 to the bottom, and the two flow guide seats 9 are respectively located directly below the air supply port 3 and the air exhaust port 4. The incoming air first flows from top to bottom. When it encounters the first flow guide seat 9, it changes from the vertical state to the horizontal state. When it encounters the second flow guide seat 9, it changes from the horizontal state to the vertical state, thus realizing air supply from above and air exhaust from above.

[0042] In this embodiment, both of the two flow guide seats 9 are made of silica gel material. In other embodiments, the flow guide seat 9 can also be made of metal material.

[0043] Regarding the air supply component 24 and the air exhaust component 25. Their structures are exactly the same. Specifically, both the air supply component 24 and the air exhaust component 25 include an iron sheet 10 arranged higher up and an air duct 11 connected to the lower end of the iron sheet 10. Below the iron sheet 10, an annular electromagnet 12 through which the air duct 11 passes is also arranged at intervals. The lower ends of the air supply port 3 and the air exhaust port 4 both have a converging step 13, and a baffle 14 is seated on the converging step 13. A return spring 15 that abuts against the baffle 14 and the iron sheet 10 is also sleeved on the air duct 11.

[0044] Correspondingly, both the air inlet 6 and the air outlet 7 have a docking pipe 16, and the sizes of the docking pipes 16 both meet the requirements for inserting the air duct 11.

[0045] In addition, the bottom of the placement box 1 is provided with a pressure sensor 17 for sensing the pressure of the cage box 8 after it is placed, and a controller 18 that is signal-connected to the pressure sensor 17. The controller 18 is controllably connected to the ring-shaped electromagnet 12 to control the disconnection and attraction between the ring-shaped electromagnet 12 and the iron sheet 10, and further control the air supply assembly 24 and the exhaust air assembly 25 to extend into the placement bin or retract into the box panel 2.

[0046] In this embodiment, both sides of the cage box 8 are fixedly connected with receiving ridges 19 for holding, so as to realize the placement of the cage box 8 into the placement box 1 and the extraction of the cage box 8 from the placement box 1.

[0047] To facilitate the survival of the animals to be experimented on, a water holding hopper 20 is further provided above the stainless steel cage net 23. A drinking water bottle is placed in the water holding hopper 20, and a drinking water port 21 for the animals to be experimented on to enter and drink water is further provided on the side of the water holding hopper 20. The cage box 8 further has a life window 22 located on the side of the water holding hopper 20 and communicating with the outside. In the event of an accidental shutdown of the breeding facility, it can absorb the outside air and reduce the possibility of the death of the animals to be experimented on.

[0048] The working principle of the novel IVC cage provided by the present utility model is as follows: When the cage box 8 is placed in the placement bin, through the induction of the pressure sensor 17, the controller 18 controls the ring-shaped electromagnet 12 in the air supply assembly 24 and the exhaust air assembly 25 to attract the iron sheet 10, so that the air ducts 11 of the air supply port 3 and the exhaust port 4 are both docked with the docking pipes 16 of the air inlet 6 and the air outlet 7, and then the air supply starts. Through the water holding hopper 20, the animals to be experimented on can replenish water in time. The internal air flow organization form of the cage box 8 is upper air supply and upper exhaust, which can effectively avoid air flow short circuit. When the cage box 8 is extracted from the placement box 1, the ring-shaped electromagnet 12 and the iron sheet 10 are powered off and separated, and the air supply assembly 24 and the exhaust air assembly 25 are retracted into the box panel 2, without being exposed outside, reducing the possibility of being polluted by the outside and reducing the frequency of manual wiping and disinfection.
