[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: an experimental tree shrew rearing cage for easy fecal cleaning and disinfection, comprising an outer frame 1, a rearing cage body 2 installed inside the outer frame 1, and a crossbar fixedly connected to the top center of the outer frame 1, the crossbar forming a handle at the top of the outer frame 1; symmetrically distributed guide rails 4 are fixedly connected to both sides of the bottom of the rearing cage body 2, and both guide rails 4 are fixedly connected to the inner side of the outer frame 1, a collection drawer 5 is fixedly connected between the two guide rails 4, and the top of the collection drawer 5 is aligned with the bottom of the rearing cage body 2; a film covering structure for covering the inside of the collection drawer 5 is installed on the rear side of the rearing cage body 2; an opening is provided on the front side of the rearing cage body 2, and the front side of the rearing cage body 2 is slidably connected to... The cage has a cage door 3 that completely covers the opening. The main body of the cage 2 is made of metal rods that are evenly distributed. The bottom front side of the main body of the cage 2 has an evenly distributed toothed structure. The top two sides of the collection drawer 5 are fixedly connected to the slide strips 8, and the slide strips 8 are slidably connected to the inner side of the two guide rails 4. The rear side of the inside of the collection drawer 5 is fixedly connected to the cleaning sleeve 10, and the top of the cleaning sleeve 10 is fixedly connected to the evenly distributed fixing rods 9. Each fixing rod 9 is slidably connected to the outer side of the metal rod at the bottom of the main body of the cage 2. The middle of the front side of the collection drawer 5 is fixedly connected to the handle 12, and the top of the handle 12 is fixedly connected to the front side of the collection drawer 5 with a clip 11. The clip 11 is made of an S-shaped elastic material.

[0027] Tree shrews are kept inside the rearing cage 2, which consists of equidistant metal rods with a hollow bottom. The tree shrews' droppings fall naturally through these holes into the collection drawer 5 at the bottom of the rearing cage 2, thus achieving centralized collection of droppings.

[0028] Sliding strips 8 are fixedly connected to the top two sides of the collection drawer 5. The sliding strips 8 slide in cooperation with the guide rails 4 on both sides of the bottom of the breeding cage. With this design, the collection drawer 5 can slide back and forth along the guide rails 4. When cleaning is required, the user only needs to pull the handle 12 on the front side of the collection drawer 5 to pull the drawer out completely from the breeding cage, allowing the device to enter. Figure 2 As shown in the diagram, the top of collection drawer 5 is fully open, facilitating thorough cleaning of the feces inside.

[0029] During the rearing of tree shrews, some feces may adhere to the metal rod at the bottom of the rearing cage body 2 due to high humidity or other reasons.

[0030] When the user pulls the collection drawer 5, the fixing rod 9 moves with the collection drawer 5, causing the cleaning sleeve 10 to slide along the metal rod. During the sliding process, the cleaning sleeve 10 uses its design of being in close contact with the metal rod to scrape the feces attached to the surface of the metal rod into the collection drawer 5.

[0031] Example 2: Based on Example 1, a film-coating structure is also disclosed, the specific structure of which is as follows: The film-coating structure includes an installation rod 6 installed on the rear side of the bottom of the feeding cage body 2, and the installation rod 6 has two symmetrically distributed on both sides of the feeding cage body 2. The two installation rods 6 are internally engaged with a winding roller 7, and the outer side of the winding roller 7 is wound with a film roll; a fixing seat 13 is installed on the inner side of the installation rod 6 and fixedly connected to one side of the feeding cage body 2, and a positioning roller 14 is rotatably connected to the outer side of the two fixing seats 13. A rotating seat 15 is rotatably connected to the inner side of the fixing seat 13, and a lower pressure roller 16 is rotatably connected between the two rotating seats 15, and the bottom of the lower pressure roller 16 and the top of the positioning roller 14 are in contact with each other.

[0032] When covering is required, first pull the collection drawer 5 from the bottom of the rearing cage body 2 to the front, so that the device is in the correct position. Figure 2 As shown, the film is drawn out from the take-up roller 7 and passed sequentially between the positioning roller 14 and the pressure roller 16, ensuring that the film can smoothly cover the area below the metal rod at the bottom of the rearing cage body 2. Then, the collection drawer 5 is pushed back into the rearing cage body 2. At this time, the film is pulled and adheres to the top of the collection drawer 5, while simultaneously covering the bottom of the drawer due to gravity, forming a protective layer. When the tree shrew produces feces, the feces will fall directly onto the film without contacting the surface of the collection drawer 5. This design effectively avoids fecal contamination of the equipment, reduces cleaning frequency, and lowers the risk of cross-infection.

[0033] When it is necessary to clean the feces, pull the collection drawer 5 out from the bottom of the breeding cage body 2 again. At this time, the covering film is brought out of the breeding cage along with the movement of the collection drawer 5. The bottom front side of the breeding cage body 2 is designed with equally spaced toothed structures. When the covering film moves to the front of the breeding cage body 2, the user can use these toothed structures to cut the covering film by applying slight force. The covering film is a disposable consumable and can be replaced every time it is used to maintain good hygiene conditions.

[0034] The cut film, along with the feces, is collected at the top of the collection drawer 5. The remaining film remains on the take-up roller 7 and is ready for the next use. The cut film and feces can be discarded directly without the need for additional cleaning of the feces adhering to the inside of the collection drawer 5. The collection drawer 5 only needs a simple rinse to be cleaned, which greatly reduces the difficulty and time of cleaning. When used in conjunction with the film, the disinfection frequency of the entire equipment is greatly reduced, saving disinfection costs and improving the operational efficiency of the laboratory.
