[0034] A filter structure for a new air system of a cultivation bottle culture room, as shown in Figures 1 to 6 .

[0035] Example one:

[0036] A filter structure for a new air system of a cultivation bottle culture room, comprising a fixed frame 1, the fixed frame 1 is installed on the wall at the air inlet of the filter chamber by expansion bolt, the clamping frame 2 is inserted on the fixed frame 1 by the sleeve frame formed by folding, and is connected with the fixed frame 1 by bolt, the inner side of the sleeve frame is provided with a sealing groove, the fixed frame 1 is provided with a sealing strip 4 of silica gel material at the corresponding position, when the clamping frame 2 is connected with the fixed frame 1 by bolt, the sealing strip 4 is inserted into the inside of the sealing groove, so that the fixed frame 1 and the clamping frame 2 can be better sealed, the clamping frame 2 is provided with a filter membrane 3, the material of the filter membrane 3 can adopt mixed cellulose ester membrane.

[0037] Example two:

[0038] ​​On the basis of the first embodiment, in order to avoid damage to the filter membrane 3 when it is subjected to excessive pressure, a clamping assembly is arranged on the clamping frame 2, which is used to clamp and fix the filter membrane 3, and when the pressure on the filter membrane 3 is greater than a set threshold value, the clamping assembly can be elastically deformed, thereby playing a buffering role to reduce the pressure on the filter membrane 3 and avoid damage to the filter membrane 3.

[0039] The clamping assembly includes a sink 5, an elastic part 6 and an insertion frame 7. The sink 5 is arranged on the side of the clamping frame 2 close to the fixed frame 1. The elastic part 6 is fixedly installed on the side slot wall of the sink 5 close to the center of the clamping frame 2. The elastic part 6 includes a clamping section and a displacement section. The insertion frame 7 is provided with a protruding strip matched with the clamping section of the elastic part 6. During installation, the filter membrane 3 is laid on the side of the clamping frame 2 provided with the sink 5, and then the insertion frame 7 is inserted into the interior of the sink 5. At this time, the insertion frame 7 and the elastic part 6 cooperate to clamp and fix the filter membrane 3.

[0040] The threshold value of the pressure on the filter membrane 3 can be controlled by controlling the elastic coefficient of the elastic part 6. For example, the greater the elastic coefficient of the elastic part 6, the higher the threshold value of the pressure on the filter membrane 3.

[0041] When the pressure on the filter membrane 3 is too large, the displacement section of the elastic part 6 will be elastically deformed, thereby playing a certain buffering role to avoid damage to the filter membrane 3.

[0042] In order to facilitate installation and further improve the sealing between the clamping frame 2 and the fixed frame 1, an insertion slot 8 is arranged on the side of the fixed frame 1 close to the clamping frame 2. The insertion slot 8 is matched with the insertion frame 7. When the clamping frame 2 is installed on the fixed frame 1, the insertion frame 7 will be inserted into the interior of the insertion slot 8, forming a labyrinth seal structure, thereby improving the sealing between the clamping frame 2 and the fixed frame 1. Moreover, after the insertion frame 7 is inserted into the interior of the insertion slot 8, it can assist in supporting the clamping frame 2, facilitating the staff to connect the clamping frame 2 and the fixed frame 1 together by using bolts.

[0043] Embodiment three:

[0044] On the basis of the second embodiment, in order to improve the sealing between the fixed frame 1 and the wall, a sealing frame 9 is fixedly arranged on the side of the fixed frame 1 away from the clamping frame 2. The sealing frame 9 is made of EPDM sealant material. When the fixed frame 1 is installed on the wall, the sealing frame 9 is elastically deformed, thereby improving the sealing between the fixed frame 1 and the wall.

[0045] The side of the fixed frame 1 away from the clamping frame 2 is folded around to form a boss. A plurality of through holes 12 are uniformly arranged on the boss along the circumferential direction of the fixed frame 1. During installation, the expansion bolts are inserted into the interior of the wall through the through holes 12, thereby fixing the fixed frame 1 on the wall.

[0046] It will be apparent to those skilled in the art that various modifications and variations can be made to the present application without departing from the spirit or scope of the application. Thus, it is intended that the present application cover modifications and variations of this application provided they come within the scope of the appended claims and their equivalents.
