[0019] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 and Figure 4 As shown, the IVC purification cage with high ventilation efficiency of the utility model mainly includes structures such as a cage box 1, an intermediate auxiliary component 3 and a cover body 4.

[0021] The cage box 1 comprises a cage body 11 with an opening at the top and a metal mesh pad 13 arranged in the cage body 11. The metal mesh pad 13 is located at the bottom of the cage body 11 and is used to isolate experimental animals and their excrement.

[0022] The cover body 4 includes a cover 41 detachably mounted on the cage body 11, an air window sealing cover 43 detachably mounted on the cover 41, a shelf slot 45 formed on the cover 41, and a water feeder 40 placed on the shelf slot 45 and extending into the cage body 11. The air window sealing cover 43 is used to filter the atmosphere in the cage body 11 to prevent it from polluting the environment; the air window sealing cover 43 can also be opened to add animal feed to the cage body 11 according to feeding needs. An air inlet valve 411 and an air outlet valve 412 are installed on the same side of the cover 41 at intervals, and the air inlet and air outlet of the IVC purification cage are realized by controlling the air inlet valve 411 and the air outlet valve 412 (the air inlet valve 411 and the air outlet valve 412 can be manually or automatically controlled by conventional existing control methods). The air inlet valve 411 is provided with an air inlet pipe 413 located in the cover 41 and extending to the opposite side. At this time, the air inlet pipe 413 is preferably extended to the side wall close to the opposite side. In this embodiment, a bellows 414 (usually a silicone tube) can be installed on the air inlet valve 411, and the air inlet pipe 413 can be detachably installed on the bellows 414 (the detachable connection method can be conventional such as plug-in or threaded connection); the bellows 414 at the front end can adapt to the movement of the air inlet valve 411 (such as retraction or extension) to reduce the impact on the silicone tube, and the air inlet pipe 413 at the rear end (non-bellows) can ensure that the resistance to air supply is small and the power consumption is small. In addition, at least one fixing buckle 415 can be installed on the air inlet pipe 413, and a card slot is opened on the inner wall of the cover 41, so that the fixing buckle 415 can be detachably carded into the aforementioned card slot, thereby achieving the fixation of the air inlet pipe 413. The intermediate auxiliary component 3 includes a mesh cover 31 disposed in the cage body 11 and located above the metal mesh pad 13, a relief portion 32 formed on the mesh cover 31 and corresponding to the rack slot 45, and a material box 33 placed in the cage box 1 and corresponding to the air window sealing cover 43 (the material box 33 is used to put in the feed). This can effectively increase the air intake stroke, thereby preventing the intake air from being discharged through the air outlet valve 412 as soon as it enters the cage, thereby improving the ventilation efficiency of the IVC purification cage (such as Figure 3 as shown).

[0023] In this embodiment, a through hole is provided at the bottom of the rack slot 45, and a rotating valve plate 46 is installed at the through hole to open or close the through hole (specifically, the rotating valve plate 46 is installed at the bottom of the rack slot 45 in a pivotal connection through a rotating shaft, and a spring that is sleeved on the rotating shaft and abuts against the valve plate 46 and the rack slot 45 is sleeved on the rotating shaft. When there is no external force, the valve plate 46 closes the through hole); the water feeding tip of the water feeder 40 extends into the cage body 11 through the through hole. When in use, the water feeding tip of the water feeder 40 is manually used to push open the valve plate 46 so that the water feeding tip extends into the cage body 11; when the water feeder 40 is manually removed, the valve plate 46 is reset to close the through hole. At this time, the air inlet pipe 413 extends to cross the rotating valve plate 46 because the length of the air inlet pipe 413 is sufficient.

[0024] In this embodiment, the IVC purification cage also includes a tray 2 arranged at the bottom of the cage box 1, and a plurality of claws 12 are installed at the lower part of the side of the cage box 1. The cage box 1 is connected to the tray 2 through the plurality of claws 12, so that the tray 2 can receive the excrement or food residues of the experimental animals in the cage box 1 and replace them in time. The connection between the cage body 11 and the tray 2 is relatively tight to ensure the sealing performance and prevent the aforementioned excrement from polluting the environment. The mesh cover 31 is provided with an escape port 311 corresponding to the material box 33. The material box 33 has an inlet corresponding to the air window sealing cover 43 and an outlet 332 opened on its side and connected to the cage body 11; the lower end face of the material box 33 is closed, and a lower baffle (corresponding to the outlet 332) is formed at the outlet 332, which is higher than the lower end face, so that the experimental animals can eat conveniently without causing the feed to be scattered.

[0025] The opening of the cage body 11 has a convex edge 111 extending outward and a plurality of buckles 112 are arranged on its side. The cover 41 is surrounded by an outer edge 42 that matches the convex edge 111. The side of the cover 41 is installed with a plurality of snap-in modules 44 that match the buckles 112, thereby realizing a detachable connection between the cage body 11 and the cover 41.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
