The mesh plates 43 are connected to both ends of the adsorption frame 41. The interior of the adsorption frame 41 and between the two mesh plates 43 are filled with activated carbon 44.

[0025] By adopting the above-mentioned technical scheme, after the adsorption frame 41 is moved and attached to the side wall of the fixed frame 42, the adsorption frame 41 and the fixed frame 42 are fixed by the fixing part 47.

The movement of the clamping screw 474 drives the fixed rod 476 to move, and the movement of the fixed rod 476 drives the reset spring 475 to stretch. When the fixed rod 476 is plugged into the plug-in frame 472 and the fixed frame 42, stop rotating the clamping screw 474, and the plug-in frame 472 and the fixed frame 42 can be fixed, and then the adsorption frame 41 and the fixed frame 42 can be fixed.

Under the sliding cooperation of the guide slider and the guide slot, a guiding effect can be provided for the movement of the fixed rod 476, thereby improving the stability of the movement of the fixed rod 476.

[0030] Specifically, a material injection pipe 45 is connected to the top of the adsorption frame 41, and an end of the material injection pipe 45 away from the adsorption frame 41 is connected to an end cap 46.

[0031] By adopting the above technical solution, when it is necessary to replace the activated carbon 44 inside the adsorption frame 41, the adsorption frame 41 is removed from the end of the fixed frame 42, and then the end cover 46 is rotated to open, and the activated carbon 44 inside the adsorption frame 41 is poured out through the injection pipe 45, and then new activated carbon 44 is taken out and injected into the adsorption frame 41 through the injection pipe 45, so as to facilitate the replacement operation of the activated carbon 44.

[0032] When the present embodiment is used, the end cover 46 is rotated to open, and new activated carbon 44 is injected into the adsorption frame 41 through the injection pipe 45, and then the adsorption frame 41 is moved to fit the side wall of the fixed frame 42, and the plug-in frame 472 is plugged into the plug-in slot 471, and then the abutting screw 474 is rotated to make it rotate and move along the connecting frame 473, and the movement of the abutting screw 474 drives the fixed rod 476 to move, and the movement of the fixed rod 476 drives the restoring spring 475 to stretch, and when the fixed rod 476 is plugged into the plug-in frame 472 and the fixed frame 42, the rotation of the abutting screw 474 is stopped, and then the handle 2 is held to open the door panel 3, and then the sea urchin to be tested is placed in the placement mechanism 8, and the door panel 3 is closed, and then The heating mechanism 7, the ventilation mechanism 6 and the ultraviolet lamp 5 are started. The ultraviolet lamp 5 provides a lighting environment for the reagent. The heating mechanism 7 heats the chamber of the test box 1 to provide a corresponding environment for the reagent. At the same time, the ventilation mechanism 6 is used to ventilate the chamber of the test box 1. During the ventilation process, the air inside the test box 1 enters the adsorption frame 41 through the fixed frame 42 and the mesh plate 43 on one side of the adsorption frame 41, and then is adsorbed and purified by the activated carbon 44, and then diffuses into the surrounding environment through the mesh plate 43 on the other side of the adsorption frame 41, thereby ensuring the operation effect of the ventilation mechanism 6. At the same time, the odor of the sea urchin inside the test box 1 can be prevented from diffusing into the surrounding environment under the action of the ventilation mechanism 6, thereby preventing the surrounding environment from being polluted;

When the handle 2 needs to be used later, the operator can hold the pull column 93 through the heat insulation sleeve 94 with his hand, and then apply force to drive the handle 2 to open the door panel 3. During the force application process, the operator's hand can be prevented from contacting the handle 2 under the action of the heat insulation plate 92, and the heat from the pull column 93 can be prevented from being transferred to the operator's hand under the action of the heat insulation sleeve 94, thereby preventing the operator from getting burned when operating the handle 2 after the heating mechanism 7 is operated.

When in use, the heating device is used to heat the interior of the test box 1. At the same time, under the action of the protective plate, the reagent in the reagent bottle component of the placement mechanism 8 can be prevented from spilling onto the heating device, thereby increasing the protection effect and improving practicality.

[0038] The structure and principle of the placement mechanism 8 composed of a reagent box and a reagent bottle in the utility model have been disclosed in a sea urchin toxicology test device disclosed in Chinese patent application No. 202110236155.5, and its working principle is: a reagent box is arranged inside the test box 1, and several reagent bottles are arranged inside the reagent box.

The movement of the tightening screw 474 drives the fixing rod 476 to move, and the movement of the fixing rod 476 drives the restoring spring 475 to stretch. When the fixing rod 476 is plugged into the plug-in frame 472 and the fixing frame 42, the rotation of the tightening screw 474 is stopped. Then the operator can hold the pull column 93 with his hand through the heat insulation sleeve 94, and then apply force to drive the handle 2 to operate and open the door panel 3. During the force application process, under the action of the heat insulation board 92, the operator can avoid The hand contacts the handle 2. Under the action of the heat insulating sleeve 94, the heat on the pull column 93 can be prevented from being transferred to the operator's hand, thereby preventing the operator from getting burned when operating the handle 2 after the heating mechanism 7 is running. After the door panel 3 is opened, the sea urchin to be tested is placed inside the placement mechanism 8, and the door panel 3 is closed. Then the heating mechanism 7, the ventilation mechanism 6 and the ultraviolet lamp 5 are started. The ultraviolet lamp 5 provides a lighting environment for the reagent.
