[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0028] As in the background art, mice tend to clump together when exposed to smoke due to external stimuli. Mice in the center may not inhale enough medication, leading to intragroup differences. In severe cases, they may suffocate and die due to insufficient air intake.

[0029] To solve this technical problem, this invention provides a mouse oil fume poisoning device, which is used in experiments on heating and poisoning kitchen oil fume substances.

[0030] For details, please refer to Figure 1 - Figure 3 The mouse oil fume exposure device specifically includes:

[0031] Combustion chamber 1, with exhaust pipe 2 fixedly connected to the top of combustion chamber 1, a guide fan 3 installed on exhaust pipe 2, and a supply pipe 4 fixedly connected to one side of exhaust pipe 2. The interior of supply pipe 4 is connected to the interior of exhaust pipe 2, and a control valve 5 is installed at the connection between supply pipe 4 and exhaust pipe 2.

[0032] The smoke supply pipe 4 is connected to the inside of the mouse poisoning chamber 6 at the end away from the exhaust pipe 2. The mouse poisoning chamber 6 contains multiple mouse cages 13 for limiting the mice. The top of the mouse poisoning chamber 6 is fixedly connected to the exhaust pipe 7, and the exhaust pipe 7 is equipped with a smoke concentration detection device 8.

[0033] The mouse fume exposure device provided by this utility model, through the coordinated design of the overall structure, can realize the fumigation process of mice. Furthermore, through the structural design of the mouse exposure chamber 6, multiple groups of mice can be tested simultaneously, and each mouse can be isolated independently. This effectively avoids the phenomenon of mice gathering together due to external stimulation during fumigation, thus ensuring that each mouse can fully inhale the fume and ensure the accuracy of the experiment.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] Example 1:

[0036] Please refer to Figure 1 - Figure 4 A mouse oil fume exposure device, comprising:

[0037] Combustion chamber 1, with exhaust pipe 2 fixedly connected to the top of combustion chamber 1, a guide fan 3 installed on exhaust pipe 2, and a supply pipe 4 fixedly connected to one side of exhaust pipe 2. The interior of supply pipe 4 is connected to the interior of exhaust pipe 2, and a control valve 5 is installed at the connection between supply pipe 4 and exhaust pipe 2.

[0038] The smoke supply pipe 4 is connected to the inside of the mouse poisoning chamber 6 at the end away from the exhaust pipe 2. The mouse poisoning chamber 6 contains multiple mouse cages 13 for limiting the mice. The top of the mouse poisoning chamber 6 is fixedly connected to the exhaust pipe 7, and the exhaust pipe 7 is equipped with a smoke concentration detection device 8.

[0039] Furthermore, a sealing door 11 is provided on the front of the mouse poisoning chamber 6. One side of the sealing door 11 is rotatably connected to the mouse poisoning chamber 6, and a lock is provided on the other side of the sealing door 11. A smoke inlet connector 9 is fixedly connected to the bottom of one side of the mouse poisoning chamber 6. The smoke supply pipe 4 is detachably and fixedly connected to the smoke inlet connector 9. A smoke exhaust connector 10 is fixedly connected to the top of the mouse poisoning chamber 6. The smoke exhaust pipe 7 is detachably and fixedly connected to the smoke exhaust connector 10.

[0040] Furthermore, in order to ensure that the flue gas can flow fully inside the mouse exposure chamber 6 and effectively ensure the accuracy of the mouse experiment, multiple partitions 12 are arranged parallel to each other inside the mouse exposure chamber 6. The multiple partitions 12 are fixedly connected to the mouse exposure chamber 6. Flue gas windows 14 are alternately opened on the left and right sides of the ends of the multiple partitions 12. A mouse cage 13 is placed on the upper end of each partition 12.

[0041] It can be seen that mice can be placed in mouse cages 13. Multiple mouse cages 13 containing mice are placed inside the mouse exposure chamber 6, thereby achieving simultaneous exposure of multiple groups of mice. The combustion chamber 1 burns substances to simulate the fumes produced after heating kitchen oil fumes. The fumes are transported into the smoke supply pipe 4 through the air guide fan 3 and the exhaust pipe 2, allowing the fumes to smoothly enter from the bottom side of the mouse exposure chamber 6. After entering the mouse exposure chamber 6, the fumes flow from the bottom to the top of the mouse exposure chamber 6 through the smoke windows 14 opened at the left and right angles of the multiple partitions 12, and finally are discharged out through the exhaust pipe 7. When the fumes pass through the mouse exposure chamber 6, multiple groups of mice in the mouse cages 13 can inhale the fumes, thus completing a smoke control experiment with different mice at the same concentration.

[0042] Example 2:

[0043] The mouse oil fume exposure device provided in Example 1 has been further optimized, specifically, as follows: Figures 5-7As shown, the mouse cage 13 includes a frame body 15. The top, bottom and rear end of the frame body 15 are all fixedly connected with outer grids 16. The inner side of the frame body 15 and the positions at the ends and middle of the outer grids 16 are all fixedly connected with inner grids 17. A grid door 18 is provided on one side of the frame body 15 and between every two adjacent inner grids 17.

[0044] Furthermore, to facilitate the opening or closing of the grille door 18, a connecting ring 19 is fixedly connected to the bottom of the grille door 18, and the grille door 18 is rotatably connected to the frame body 15 through the connecting ring 19. A connecting buckle 20 is fixedly connected to the top of the grille door 18, and the grille door 18 is fastened to the frame body 15 through the connecting buckle 20.

[0045] Furthermore, in order to improve the overall stability and sturdiness of the mouse cage 13, the frame body 15, the outer grid 16, and the inner grid 17 are all fixed by welding.

[0046] Through the above structural design, multiple mice can be independently isolated through the mouse cage 13. In use, multiple mice are placed inside the outer grid 16, and the inner grid 17 is used to isolate the multiple mice. The grid door 18 can block the mice after they are placed to prevent them from accidentally running out. Thus, by placing multiple mouse cages 13 with mice inside the mouse poisoning chamber 6, multiple groups of mice can be confined, with each group containing multiple mice.
