[0024] In one embodiment of this utility model, the flat pull assembly 2 includes a sliding guide rail 101, a sliding guide block 102, a mesh plate 103, a support block 104, a limiter 105, and an operating handle 106. Several parallel sliding guide rails 101 are fixedly connected to the inner walls of both sides of the breeding cabinet 1. Sliding guide blocks 102 are slidably connected to the sliding guide rails 101. A mesh plate 103 is fixedly connected between two sets of sliding guide blocks 102 at the same level. Support blocks 104 are fixedly connected to the four corners of the upper end of the mesh plate 103. Slots 107 are provided on the support blocks 104, and the four corners of the breeding frame are respectively fitted into the slots 107.

The limit plate 206 abuts against the other end of the limit block 201. The other end of the sliding rod 203 passes through the spring groove and is fixedly connected to the buffer plate 204. A buffer spring 205 is sleeved on the sliding rod 203 located in the spring groove. A buffer spring 205 has one end that abuts against the bottom of a spring groove, and the other end that passes through the spring groove and abuts against a buffer plate 204. Guide rods 202 are fixedly connected to the buffer plates 204 on both sides of the sliding rod 203. A guide groove is provided on a limiting block 201 on one side of the guide rod 202. The guide rods 202 are slidably connected in the guide groove. When the perforated plate 103 is pulled outward, the perforated plate 103 drives the sliding guide blocks 102 on both sides to slide outward. The sliding blocks drive the lower limiting block 201 to move until the buffer plate 204 touches the frame. At this time, the buffer spring 205 provides a buffering effect on the impact of the buffer plate 204, avoiding a violent collision between the limiting block 201 and the cabinet frame.

[0026] In one embodiment of this utility model, the air circulation device 9 includes an outer casing 301, a first fixing plate 302, a second fixing plate 303, a heat exchange pipe 304, an exhaust casing 305, a mounting plate 306, and a circulating fan 307. The outer casing 301 is fixedly connected to the back of the breeding cabinet 1. An air duct 309 is formed inside the outer casing 301. The upper end of the air duct 309 is connected to the air outlet chamber. The first fixing plate 302 is fixedly connected inside the air duct 309 located on one side of the air outlet chamber. A fan is embedded in the first fixing plate 302. Several heat exchange tubes 304 are fixedly connected at their lower ends to a second fixed plate 303.

A plurality of circulating fans 307 are connected, and the lower end of the air duct 309 is connected to the air inlet chamber. In this embodiment, during specific operation, external air enters the air duct 309 through the air inlet slot 308 and flows downward along the air duct 309. During this process, the circulating fans 307 realize the intake and propulsion of air flow. The incoming air undergoes heat exchange when flowing through the heat exchange tube 304, preheating the incoming air. Then, the air is humidified by the humidification device 11, and then reheated by the heating grille plate. The air then enters the air inlet chamber 3, and then enters the breeding cabinet 1 through the air inlet 4. The air inside the breeding cabinet 1 enters the air outlet chamber 5 through the air outlet 6. The air outlet chamber 5 sends the air inside the breeding cabinet 1 into the upper end of the air duct 309, and then enters from the end of the heat exchange tube 304 at the upper end of the first fixed plate 302. It then enters the exhaust shell 305 along the heat exchange tube 304. During this process, it exchanges heat with the air entering from the outside through the heat exchange tube 304, and finally exits through the opening on one side of the exhaust shell 305, thus forming an air exchange cycle.

[0027] In one embodiment of this utility model, the humidification device 11 includes a blower 401, a humidifier 402, and an air duct 403. The blower 401 is installed on one side of the breeding cabinet 1, and the humidifier 402 is fixedly connected to one side of the blower 401. The air duct 403 is fixedly connected to one side of the humidifier 402. One end of the air duct 403 passes through the outer cover 301 and is connected to the air duct 309. Several air vents 404 are opened on the air duct 403 located in the air duct 309. When in use, the humidifier 402 atomizes the water, and the blower 401 blows the atomized water vapor into the air duct 403. Finally, the water vapor is blown out from the air vents 404 on the air duct 403, and the blown water vapor mixes with the air in the air duct 309, thereby increasing the humidity of the incoming air.
