[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] The air composition controller of this embodiment includes a cylinder 1, on which a first air inlet 2, a first exhaust port 3, a second air inlet 4 and a second exhaust port 5 are provided in the radial direction. The centers of the first air inlet and the first exhaust port are located on a radial section of the cylinder, and the centers of the second air inlet and the second exhaust port are located on another radial section of the cylinder.

[0017] The air component controller further comprises a fan 6 connected to the first air inlet. In this embodiment, the housing of the fan 6 is connected to the first air inlet 2 via a flange and screws, which is convenient for assembly and disassembly.

[0018] The air component controller further includes a filter, which includes a housing 7 and a filter element 8 disposed in the housing, and the housing is provided with a first interface 9 connected to the first exhaust port 3 and a second interface 10 connected to the second air inlet 4. In this embodiment, the first exhaust port 3 and the first interface 9 are connected by a flange and screws, and the second air inlet 4 and the second interface 10 are also connected by a flange and screws, so that the filter can be easily disassembled. In addition, in this embodiment, the axial end of the housing 7 is provided with a port and an end cover 11 for loading the filter element, so that the loading and removal of the filter element are simple and convenient.

[0019] In specific implementation, the filter element 8 can be selected according to actual needs. For example, if it is necessary to filter out moisture in the air, a water vapor filter element that removes water vapor is selected; if it is necessary to filter out carbon dioxide in the air, a carbon dioxide filter element that removes carbon dioxide is selected; of course, several filter elements can also be used in combination.

[0020] The air composition controller also includes a control component for controlling the on-off of the air path between the first air inlet and the first exhaust port, and between the second air inlet and the second exhaust port. The control component includes a first piston 12 and a second piston 13 arranged in the cylinder, a piston rod 14 connecting the first piston and the second piston, and an electric push rod 15 arranged at one axial end of the cylinder. The first piston and the second piston are respectively slidably sealed with the inner wall of the cylinder. The center distance between the first piston and the second piston is equal to the center distance between the first air inlet and the second exhaust port. The telescopic rod of the electric push rod is connected to the piston rod; a degassing port 16 is provided at the other end of the cylinder.

[0021] When air supply is not required in plant or bacterial culture, the electric push rod can be controlled to push the first piston and the second piston to between the first air inlet and the first exhaust port and between the second air inlet and the second exhaust port, respectively, so that the air flow is blocked and no air is discharged from the second exhaust port. When air supply is required in plant or bacterial culture, the electric push rod can be controlled to push the first piston and the second piston forward so that they leave from between the first air inlet and the first exhaust port and between the second air inlet and the second exhaust port, respectively. At this time, the air is driven by the fan and discharged through the first air inlet, the first exhaust port, the filter, the second air inlet and the second exhaust port in sequence, thereby realizing the supply of air flow. Since the end of the cylinder is provided with an air outlet 16, when the first piston moves forward, the air at the end of the cylinder is discharged from the air outlet 16, which will not hinder the movement of the piston, thereby ensuring the flexibility of the movement of the piston.

[0022] As an improvement to the above embodiment, the degassing port is connected to the filter via an air pipe 17. This improvement prevents air from entering or leaving the air composition controller from other locations except the first air inlet 2 and the second air outlet 5, which is more conducive to accurate control of air composition and flow.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
