[0031] Combine the following Figures 1 to 4 The embodiments of the present utility model are described.

[0032] The present embodiment relates to a carbon box valve structure, which can conveniently wire a driver for driving the valve to open and close, and can conveniently inspect or clean the activated carbon inside the box body 1.

[0033] The carbon box valve structure of this embodiment includes:

[0034] The box body 1 includes a first smoke outlet 12 located at the bottom side and a second smoke outlet 11 located at the front side;

[0035] The valve assembly includes a valve driver 21 and a door plate 22. The valve driver 21 is arranged outside the box body 1, and the door plate 22 is located inside the box body 1. The door plate 22 is hinged to the box body 1. The driving end of the valve driver 21 passes through the box body 1 and is driven and connected to the door plate 22, driving the door plate 22 to open and close the first smoke outlet 12.

[0036] The box 1 is placed in a smoke filter system, and a smoke passage is formed between the first smoke port 12 and the second smoke port 11 inside the box 1. After the box 1 is filled with activated carbon or other filter materials, smoke can filter out some of the oil smoke or dust when passing through the smoke passage.

[0037] It can be understood that when the valve body 1 is in a state of filtering smoke, the valve assembly keeps the first smoke port 12 in a closed state.

[0038] The carbon box valve structure sets the valve driver 21 outside the box body 1, and the connection line of the valve driver 21 can be directly routed outside the box body 1, which is convenient for wiring. The valve driver 21 can also be repaired outside, which is convenient for operation.

[0039] The valve driver 21 is a linear driver, and the valve assembly further includes a hinged joint 23 and a pull rod 24. The hinged joint 23 and the pull rod 24 are both located in the housing 1. The driving end of the valve driver 21 is connected to the pull rod 24 by driving. One end of the pull rod 24 away from the valve driver 21 is connected to the hinged joint 23, and the other end is hinged to the door plate 22. When the valve driver 21 is a linear driver, the valve driver 21 can only output reciprocating motion in a linear direction. The output end of the valve driver 21 drives the hinged joint 23, and when the valve driver 21 is actuated, the pull rod 24 is driven to move, and the door plate 22 is pulled by the pull rod 24 to open and close the first smoke outlet 12.

[0040] The valve assembly also includes a connecting plate 221, a screw (not shown in the figure) and a nut (not shown in the figure). The connecting plate 221 is located inside the box 1. The connecting plate 221 is fixedly connected to the door plate 22. The connecting plate 221 is provided with an elongated hole. The lower end of the hinge head 23 is provided with a through hole. The screw passes through the through hole and the elongated hole and is threadedly connected with the nut. The elongated hole provided on the connecting plate 221 enables the through hole and the elongated hole to have a plurality of positions that can correspond to each other, so that when assembling the valve assembly, the position of the through hole in the elongated hole can be adjusted to compensate for the error, reduce the demand for assembly accuracy, and reduce the difficulty of assembly. After the screw passes through the through hole and the elongated hole, the nut plays a role in limiting the connection plate 221 and the pull rod 24 from being separated. When the pull rod 24 is driven by the valve driver 21 and the hinge head 23, the position of the pull rod 24 is driven to change, and the door plate 22 is pulled up or lowered through the connecting plate 221 to open or close the first smoke outlet 12.

[0041] There are two connecting plates 221 , and the pull rod 24 is located between the two connecting plates 221 . The screw passes through the elongated hole, the through hole, and the elongated hole on the first connecting plate 221 in sequence, and then is threadedly connected with the nut.

[0042] The position where the valve driver 21 is connected to the housing 1 is located in the middle of the housing 1. Compared with installing the valve driver 21 offset outside one side of the housing 1, the valve driver 21 is installed in the middle of the housing 1, which has less impact on the center of gravity of the housing 1, reduces the difficulty of installing the housing 1, and reduces space occupation.

[0043] There are two first smoke vents 12, which are separated by a connecting rib 13 provided at the lower side of the box body 1, and the two first smoke vents 12 are arranged in mirror symmetry with respect to the connecting rib 13. There are two valve assemblies, which are arranged in mirror symmetry with respect to the connecting rib 13. The connecting rib 13 is provided at the bottom of the box body 1 to strengthen the structural strength of the box body 1, and two valve assemblies are provided to open and close the lower side of the box body 1, which can reduce the size of a single door panel 22 and increase its load-bearing capacity.

[0044] The door panel 22 is provided with reinforcing ribs 222. The reinforcing ribs 222 can increase the structural strength of the door panel 22 and increase its ability to bear the weight of the activated carbon.

[0045] In the carbon box valve structure of the present invention, the first smoke vent 12 is a smoke inlet, and the second smoke vent 11 is a smoke outlet. Alternatively, the first smoke vent 12 is a smoke outlet, and the second smoke vent 11 is a smoke inlet.

[0046] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
