When the two chambers are used independently, the partition structure is located in the middle to separate the two chambers. The two chambers are independent and do not affect each other. When a larger product needs to be placed, it is only necessary to rotate the middle revolving door 1 to be parallel to the back side of the test box (rotate the middle revolving door 1 to a side of the middle revolving door 1 adjacent to or close to the back side of the test box), and remove the bottom removable plate 2 and the column 21 to connect the two chambers into one chamber. After placing the product, the column 21 can be installed, so that the switching between single and double chambers can be easily realized, and the middle revolving door 1 will not block the air outlet 18 at the upper back side of the test box and the return air outlet 19 at the lower back side of the test box when it is rotated to be parallel to the back side of the test box.

[0034] Specifically, the rear side of the test box is provided with a unit corresponding to each chamber (wherein 7 is the A chamber unit, i.e., the unit corresponding to chamber A; 8 is the B chamber unit, i.e., the unit corresponding to chamber B), and the top of the test box is provided with a pressure relief door 5 and an exhaust fan 6; when the product in the box explodes and generates pressure, the pressure relief door 5 will instantly pop open to release the pressure in the box, and a large amount of smoke will be generated in the event of a fire, which can be removed by the exhaust fan 6. A smoke alarm 16 is also provided on the top of the test box to promptly alarm in the event of a fire.

[0035] In this embodiment, the above-mentioned middle rotatable door 1 is rotatably connected to the rear inner wall of the test box through a hinge, an emergency door lock 20 is arranged on the front side of the above-mentioned middle rotatable door, and a hook (not shown in the figure) compatible with the emergency door lock 20 is arranged on the rear inner wall of the above-mentioned test box; when the middle rotatable door 1 is closed, the middle rotatable door 1 can be pressed against the column 21 by the emergency door lock 20, so that the middle rotatable door 1 can be fixed; when the middle rotatable door 1 is opened, the emergency door lock 21 can be hung on the hook through the hollow hole of the emergency door lock 21, so that the middle rotatable door 1 can be fixed; the above-mentioned bottom detachable plate is detachably connected to the bottom inner wall of the test box by plugging; and sealing strips are arranged on all sides of the above-mentioned middle rotatable door 1.

[0036] In this embodiment, when the middle revolving door 1 is in a coordinated closed state with the top crossbeam 3 and the bottom removable plate 2, the entire box body can be independently divided into cavity A and cavity B, and the two cavities can be used independently, so that the existing equipment can be effectively utilized to save energy and reduce emissions for different tests; when the middle revolving door 1 is in an open state and the bottom removable plate 2 is removed from the test box body (the bottom removable plate 2 is moved to the outside of the test box body), cavity A and cavity B are connected together to form a large cavity, so that larger products (products that cannot be placed in a single cavity A or cavity B) can be placed in it for testing, and this embodiment is cleverly designed so that when the middle revolving door 1 is rotated open, it will not block the air outlet 18 and return air outlet 19 on the rear side of the box body, thereby meeting the diversity of customer products while saving resources; and the single and double cavities are easy to switch, and have a good market prospect.

[0037] Embodiment 2:

[0038] like Figure 5 and 6 As shown, the utility model discloses a double-chamber environmental test box, which has a substantially similar structure to the double-chamber environmental test box of the above-mentioned embodiment, and the only difference is that the double-chamber environmental test box in the present embodiment further includes a water injection fire extinguishing structure; the water injection fire extinguishing structure includes a water inlet pipe 10 and a water outlet pipe 13; the two ends of the water inlet pipe 10 are respectively connected to a water source and a chamber (the A chamber and the B chamber are respectively connected to the water inlet pipe 10), and the water outlet pipe 13 is arranged at the bottom of the side wall of the test box and is connected to the chamber (the A chamber and the B chamber are respectively connected to the water outlet pipe 13); the water inlet pipe 10 is provided with a first electric valve 11 and a first manual valve 12, and the first manual valve 12 is connected in parallel with the first electric valve 11, and the water outlet pipe 13 is provided with a second electric valve 14 and a second manual valve 15, and the second manual valve 15 is connected in series with the second electric valve 14; the smoke alarm 16 is respectively connected to the first electric valve 11 and the second electric valve 14 in communication. Specifically, the two chambers of the test box are both provided with floats 17 .

[0039] When the smoke alarm 16 detects that the test product has a fire (or other fire situation), the double-chamber environmental test chamber in this embodiment will immediately control the first electric valve 11 to open the water inlet pipe 10 to release water into the chamber, and control the second electric valve 14 to close the drainage. After that, water will accumulate in the chamber to a certain height, so as to achieve the effect of extinguishing the fire. When the fire is injected, if the first electric valve 11 and / or the second electric valve 14 are out of control and damaged, the first manual valve 12 and / or the first manual valve 12 switch can be manually controlled to effectively inject water. The water level is controlled by the float 17, and when the product in the box explodes and generates pressure, the pressure relief door 5 will instantly pop open to release the pressure in the box. When a fire occurs, a large amount of smoke will be generated, which can be removed by the exhaust fan 6.
