Description

Technical Field

[0001] This utility model relates to the technical field of mushroom cultivation devices, specifically to a sample return device for a spawn chamber. Background Technology

[0002] To ensure the bio-production workshop achieves a sterile state, dynamic biosafety monitoring is required. This involves sampling and re-inoculation of the inoculation equipment in the inoculation room. After sterilization, sampling points are selected on the equipment, and the samples are then placed back into the culture medium for microbial testing to check whether sterilization is complete.

[0003] The existing sample return device for the culture room uses an inoculation box. In order to ensure the sterility of the inoculation box, it is necessary to fumigate the inoculation box with a fumigation disinfectant before inoculation. That is, the fumigation disinfectant (such as sodium urate) is ignited and the fumigation is filled with smoke to sterilize the inoculation box. After sealing for a period of time, ventilation is carried out before the return operation can be carried out. The fumigation disinfectant can thoroughly eliminate dead corners through three-dimensional disinfection of the smoke.

[0004] Traditional inoculation boxes have the following problems when used as sample return devices in the culture room: traditional inoculation boxes cannot guarantee complete airtightness during fumigation and disinfection, resulting in air leakage. A small amount of smoke will escape during the sterilization process, which will affect the environment and operators. Utility Model Content

[0005] In order to overcome the problems in the background technology, this utility model provides a sample return device for the inoculum chamber, which solves the problem that when the traditional inoculation box is used as a sample return device for the inoculum chamber for fumigation and disinfection, it cannot guarantee complete air sealing and there is air leakage. During the sterilization process, a small amount of smoke will escape and affect the environment and operators.

[0006] A sample return device for a microbial culture chamber includes a protective outer box, a return cover, a lifting device, an air extraction interface, and an air inlet. The protective outer box has observation windows detachably installed on both sides, an operation port on the front side, a through hole on the top, and a support at the bottom. The return cover is a transparent cover installed inside the protective outer box, and operating gloves are provided on the return cover corresponding to the operation port. The lifting device is located on the top of the protective outer box and connected to the return cover through the through hole. The air extraction interface and the air inlet are located opposite each other on both sides of the protective outer box.

[0007] Furthermore, the lifting device includes a lifting plate, a lifting rod, and a limiting block. The lifting plate is connected to the top of the lifting rod, the bottom of the lifting rod is connected to the top of the return cover, and the limiting block is slidably installed on one side of the lifting plate.

[0008] Furthermore, a sealing cap is installed on the operating port.

[0009] Furthermore, a rotating flap is installed inside the air extraction port via a rotating shaft, and a one-way valve is installed inside the air inlet.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This application is equipped with a protective outer casing, a return cover, an exhaust port, and an air inlet. Fumigation and disinfection can be carried out inside the return cover. The design of the protective outer casing, exhaust port, and air inlet outside the return cover ensures timely ventilation to remove any escaping fumes, preventing any impact on the operating room environment. This solves the problem that traditional inoculation boxes, when used as sample return devices in a culture chamber for fumigation and disinfection, cannot guarantee complete airtightness and leaks, resulting in a small amount of fumes escaping during sterilization and affecting the environment and operators.

Detailed Implementation

[0018] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0019] This utility model discloses a sample return device for a microbial culture chamber, see reference. Figure 1-4A sample return device for a microbial culture chamber includes a protective outer box 1, a return cover 2, a lifting device 3, an air extraction interface 4, and an air inlet 5. The protective outer box 1 has observation windows 11 detachably installed on both sides, an operation port 12 is provided on the front side of the protective outer box 1, a through hole is provided on the top of the protective outer box 1, and a support 13 is provided at the bottom of the protective outer box 1. The return cover 2 is a transparent cover installed inside the protective outer box 1, and an operating glove 21 is provided on the return cover 2 corresponding to the operation port 12.
