[0002] Animal models are very valuable for further studying the pathogenesis and treatment of human COPD. Rodents, in particular, are widely used in medical research due to their advantages such as low price, short breeding cycle, and clear genetic spectrum. Using model preparation devices to establish stable and reliable animal models that are consistent with clinical practice is the prerequisite and key to the success of the experiment.

[0003] According to Chinese patent publication number CN218649665U, a fumigation modeling box for animal experiments includes a glass box, a transfer box, a gas generator and an exhaust structure; the transfer box is arranged inside the glass box and can be taken out from the glass box, the gas generator is fixedly connected to the side of the glass box, the exhaust structure is fixedly connected to the side outside the glass box, and a blocking plate is provided at the connection between the gas generator and the glass box, and the blocking plate is movably connected to the gas generator.

[0004] When smoke is input into the smoking modeling box in this announcement during use, the cigarette smoke is allowed to pass through the rectangular block into the glass box through the gas generator, and multiple experimental animals are separated by partitions in the transfer box, and the smoke enters from one side of the glass box. Therefore, it takes a certain amount of time for the smoke to spread evenly in the box, resulting in the animals close to the smoke inlet side may inhale more smoke, while the animals far from the smoke inlet inhale less. As a result, there may be a large difference in the amount of smoke inhaled by the animals, which may easily affect the experimental results. Therefore, a smoking modeling box for experimental animals is proposed. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 An experimental animal fumigation molding box in this embodiment includes a test box 1, a gas generator 2 is provided on the top of the test box 1, a smoke purifier 3 is provided on the side wall of the test box 1, a mesh plate 7 is provided inside the test box 1, a collection box 6 is placed below the mesh plate 7 on the inner bottom wall of the test box 1, a cover shell 9 is provided on the top of the mesh plate 7, and a connecting piece is provided between the cover shell 9 and the gas generator 2.

[0023] The smoke purifier 3 is an existing technology. The smoke purifier 3 adopts negative ion technology and amino-based active materials, which can purify PM2.5 molecules in the smoke. At the same time, it can also process harmful substances such as formaldehyde.

[0024] The connecting part includes a telescopic tube 11, one end of which is connected to the gas generator 2, and a plug-in tube 13 is fixedly connected to the side of the telescopic tube 11 away from the gas generator 2. A ring block 14 is fixed to the outside of the plug-in tube 13, and the left and right side walls of the ring block 14 are both provided with limiting grooves 15. The inner top wall of the cover 9 is provided with a diverter box 10, and the bottom of the diverter box 10 is provided with multiple smoke outlets. The inside of the diverter box 10 and the cover 9 are both provided with corresponding sockets 20, and the plug-in tube 13 is plugged into the inside of the socket 20.

[0025] By setting up the diversion box 10, the incoming smoke first passes through the telescopic tube 11 into the diversion box 10 and spreads out, and finally is discharged from multiple smoke outlets into the cover 9, so that the smoke can be evenly distributed inside the cover 9, thereby avoiding large differences in the smoke inhaled by the experimental animals covered inside the cover 9. At the same time, the telescopic tube 11 used to connect the gas generator 2 and the cover 9 can be removed from the cover 9 to facilitate the subsequent removal of the cover 9 and the mesh plate 7.

[0026] See also Figure 1 、 Figure 2 In this embodiment, a limiting member of a limiting annular block 14 is provided at the top of the cover shell 9, and the limiting member includes a slide plate 17. The side of the slide plate 17 close to the annular block 14 is fixedly connected to the limiting block 18. The limiting block 18 is adapted to the limiting groove 15. A slide groove is provided at the top of the cover shell 9, and a slide rod 16 is provided inside the slide groove. The slide plate 17 is slidably connected to the outside of the slide rod 16, and the outside of the slide rod 16 is provided with a telescopic spring 19 that abuts against the side wall of the slide plate 17.

[0027] The movable slide 17 can be used to conveniently pull the limiting block 18 out of the limiting groove 15 , and the plug-in tube 13 can be pulled out of the plug-in hole 20 , thereby conveniently separating the telescopic tube 11 and the cover shell 9 .

[0028] See also Figure 1 In this embodiment, side panels 12 are provided on the left and right inner walls of the test box 1, side grooves are provided on the left and right sides of the mesh plate 7, and the side panels 12 are clamped inside the side grooves. Slots 22 are provided on both sides of the bottom of the cover shell 9, and two positioning clips 8 are provided on the top of the mesh plate 7, which are inserted into the inside of the slots 22.

[0029] The front of the test box 1 is hinged with a box door 23 , the front of the cover 9 is provided with a transparent plate 21 , and the left and right sides of the cover 9 are both provided with a plurality of air outlets.

[0030] When the box door 23 is opened, the mesh plate 7 can be pulled out of the test box 1, and the cover 9 can be separated from the mesh plate 7, so as to facilitate cleaning the mesh plate 7 or taking out the experimental animal.

[0031] In this embodiment, an exhaust port 4 is provided on a side wall of the test box 1 and is located on one side of the smoke purifier 3 . An exhaust fan 5 is provided inside the exhaust port 4 .

[0032] It should be noted that a controller is provided on the side wall of the test box 1, and the exhaust fan 5 is electrically connected to the controller. Through the setting of the air outlet, the smoke in the cover 9 is discharged through the air outlet and can be sucked out by the exhaust fan 5 and then purified by the smoke purifier 3 before being discharged into the environment.

[0033] The working principle of the above embodiment is as follows: when in use, the experimental animal is first placed on the mesh plate 7 and the cover 9 covers the animal. Pulling the two slides 17 in opposite directions will squeeze the telescopic spring 19 to make it telescopic, and then the plug tube 13 can be inserted into the socket 20. After releasing the hand, the rebound force of the telescopic spring 19 can make the limit block 18 insert into the inner part of the limit groove 15, thereby limiting the annular block 14, so that the telescopic tube 11 can be connected to the gas generator 2 and the diversion box 10, and the smoke generated by the cigarette is discharged into the gas generator 2 through the gas generator 2. The smoke enters the telescopic tube 11, and then passes through the plug-in tube 13 to enter the diversion box 10 and diffuse, and finally is discharged from multiple smoke outlets into the internal space of the cover 9, so that the smoke can be evenly distributed in the cover 9 for smoke modeling experiments, thereby avoiding the situation where the experimental animals covered in the cover 9 inhale large differences in the smoke. When the experiment is over, the exhaust fan 5 can be turned on to extract the internal smoke and discharge it after purification through the smoke purifier 3. The collection box 6 is used to collect the feces produced by the animals during the experiment.
