[0027] Embodiment

[0028] This embodiment provides a plant callus cultivation chamber cover, which is used in cooperation with the cultivation chamber and covers the cultivation chamber during use. Its structure is referred to Figure 1 and Figure 2 , and includes a chamber cover body.

[0029] A multi-filter check air inlet valve 4 is provided on the chamber cover body. The multi-filter check air inlet valve 4 penetrates through the chamber cover body, and the air inlet end is located outside the chamber cover body (referring to the side of the chamber cover body in contact with the air, hereinafter all represented by the outside), and the air outlet end is located inside the chamber cover body (referring to the side of the chamber cover body close to the cultivation chamber, actually inside the cultivation chamber, hereinafter all represented by the inside). The multi-filter check air inlet valve 4 is used to unidirectionally supply pure air into the cultivation chamber inside the chamber cover body.

[0030] The multi-filter check air inlet valve is an air inlet valve with multi-filter and check functions. It consists of a valve body, a valve flap, a spring, and a set of filtering devices. The valve body has an air inlet end and an air outlet end. During use, the air inlet end is connected to an air filter, and the air outlet end leads into the cultivation chamber. The valve flap is a movable component located on the outer side of the top of the hatch body between the air inlet end and the air outlet end, and its opening and closing can be controlled by the elastic force of the spring.

[0031] When air enters from the air inlet end, the multi-filter check air inlet valve will perform multi-stage filtration on the air to remove impurities and moisture therein. The filtering device includes a primary filter and a high-efficiency filter. The primary filter can remove larger impurities and dust, while the high-efficiency filter can remove finer particulate matter and bacteria.

[0032] In addition to the filtering function, the multi-filter check air inlet valve 4 also has a check function. When the pneumatic system needs to stop working, the valve flap will close under the action of the spring to prevent air from flowing out of the air outlet end. This can prevent external impurities and moisture from entering the pneumatic system, thus protecting the normal operation of the system.

[0033] A check air outlet valve 6 is also provided through the hatch body for unidirectionally discharging the gas metabolized by the plant tissue culture in the inner cultivation chamber of the hatch body.

[0034] Preferably, for a plant callus cultivation hatch cover in this embodiment, the air inlet end of the check air outlet valve 6 is located inside the hatch body, and the air outlet end of the check air outlet valve 6 is located outside the hatch body.

[0035] During actual use, when the gas or liquid in the cultivation chamber needs to flow out, the valve flap of the check air outlet valve will open to allow the gas or liquid to flow out. When the gas or liquid in the pipeline needs to flow back, the valve flap of the check air outlet valve will close to prevent the gas or liquid from flowing back into the cultivation chamber, maintaining a pure cultivation environment in the cultivation chamber.

[0036] Safety buckles 2 are also provided on the peripheral side edges of the hatch body. The safety buckles 2 are used to fasten to the cultivation chamber inside the hatch body. In this embodiment, two safety buckles 2 are provided on each side of the hatch body. The safety buckles 2 are set as double-buckle fasteners, and connection bumps matching the safety buckles 2 are provided on the top side edges of the lower cultivation chamber. During installation, the hatch body is covered on the outer side of the cultivation chamber, and the safety buckles 2 around the hatch body are fastened to the connection bumps of the cultivation chamber.

[0037] Preferably, for a plant callus cultivation hatch cover in this embodiment, a groove ring is provided on the inner side of the hatch body near the outer side edge, and a silica gel sealing ring 3 is provided inside the groove ring. During installation, the silica gel sealing ring 3 is pressed tightly on the upper port of the cultivation chamber to enhance the connection sealing performance between the hatch cover and the cultivation chamber.

[0038] Preferably, for a plant callus cultivation chamber cover according to this embodiment, a spare air inlet valve interface 5 is also provided through the chamber cover body. The height of the air inlet end of the spare air inlet valve interface 5 outside the chamber cover body is lower than that of the multi-filter check air inlet valve 4. During use, the connection position can be flexibly adjusted according to the length of the air delivery pipeline, which is convenient for replacing the air delivery channel when the air delivery pipe in the cultivation chamber is blocked.

[0039] Preferably, for a plant callus cultivation chamber cover according to this embodiment, a buckle handle structure 1 is provided on the chamber cover body. During use, the operator's hands are grasped inside the buckle handle structure 1, which is convenient for taking the chamber cover body.

[0040] It should be noted that the multi-filter check air inlet valve 4, the spare air inlet valve interface 5, and the check air outlet valve 6 are all hermetically and tightly connected to the chamber cover body.

[0041] The working principle of the present utility model is as follows: Before use, first use the flowing water method to detect the smoothness of the heavy-filter check air inlet valve 4, the spare air inlet valve interface 5, and the inner air inlet pipe, and detect the exhaust smoothness of the check air outlet valve 6. After verifying that the silicone rubber sealing ring 3 is closely and seamlessly connected to the upper port of the cultivation chamber without falling off, align and buckle the chamber cover on the cultivation chamber body, then press the safety locks 2 around, and lock and seal the chamber body after locking. Then, perform high-temperature and high-pressure disinfection on the whole and wait for planting and use.

[0042] During use, it must be operated on a dust-free clean workbench. The inner side of the opened cover body is oriented towards the air flow surface of the clean workbench. Then, place the selected plant callus in the cultivation chamber. After injecting the culture medium, align and buckle the chamber cover on the chamber body, and press the locks around to lock it.

[0043] Inspired by the above ideal embodiments based on this application, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this application. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
