[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] First embodiment: See appendix Figures 1 to 7 The present invention discloses a mushroom-shaped chamber with alternating hot and cold temperature stimulation, which mainly includes a chamber body 1, a dual-circuit air collection box 2, a linkage flap assembly 3, and an air outlet balancing structure 4.

[0023] The following section will elaborate on the composition, assembly relationship, and collaborative working method of each part.

[0024] The chamber 1 is a box structure with an insulated interlayer. A dual-loop air collection box 2 is installed on its top. The dual-loop air collection box 2 is divided into an independent low-temperature static pressure chamber 22 and a high-temperature static pressure chamber 23 by a partition 21. The linkage flap assembly 3 is installed inside the chamber 1 and is close to the bottom surface of the dual-loop air collection box 2. It is displaced by the sealing component 31 to achieve alternating coverage of the low-temperature air outlet 24 and the high-temperature air outlet 25. The air outlet balancing structure 4 is suspended by a bracket on the top of the chamber 1 below the low-temperature air outlet 24 and the high-temperature air outlet 25 to receive and process the discharged hot and cold airflow.

[0025] Overall working principle: The external refrigeration unit and heating unit continuously supply cold air and hot air to the low-temperature static pressure chamber 22 and the high-temperature static pressure chamber 23 respectively, so that a stable static pressure environment is formed in the chamber. According to the preset instructions, the controller 6 drives the mechanism 32 to run and moves the sealing component 31 to the position of blocking the high-temperature air outlet 25. At this time, the low-temperature air outlet 24 is fully open and the cold air is sprayed downward. Before entering the mushroom cultivation area below, the airflow is physically divided and rectified by the honeycomb static mixing grid 41, thereby transforming the local high-speed laminar flow into a uniformly diffused micro-turbulent flow. This ensures the rapid transformation of the temperature gradient and avoids direct damage to the mushrooms by extremely cold or hot airflow.

[0026] Second embodiment: To clearly illustrate the technical solution of the present invention, the following detailed description is provided in conjunction with specific embodiments. The second embodiment is a basic implementation of the dual-loop air collection box 2, as detailed below:

[0027] The bottom plane of the dual-loop air collection box 2 has parallel low-temperature air outlets 24 and high-temperature air outlets 25. To prevent leakage during airflow switching, a protruding sealing flange extends from the edge of each air outlet toward the interior of the chamber. A high-resilience, heat-resistant silicone sealing strip is attached to the flange. When the sealing member 31 moves to the closed position, the surface of the sealing member 31 forms a tight end face contact with the silicone sealing strip. The sealing strip is pressed by mechanical driving force, thereby completely blocking the leakage of unselected airflow. This design effectively solves the problem of decreased temperature control accuracy caused by the mutual flow of hot and cold airflows in traditional variable temperature equipment, and ensures the stable release of pressure in the static pressure chamber.

[0028] Third embodiment: Based on the above-described basic implementation method, the present invention also provides a third embodiment, which corresponds to the specific implementation of the air outlet balance structure 4, as follows:

[0029] The core of the air outlet balancing structure 4 lies in the honeycomb static mixing grid 41, which is composed of a multi-layered array of intersecting hexagonal thin-walled channels. The honeycomb static mixing grid 41 is fixed to the mounting bracket located at the top of the cabin 1 by anti-rust bolts. Its wind-receiving surface completely covers the confluence area of ​​the jet streams from the two air outlets. The function of this grid is not only to divert the flow, but also to absorb the kinetic energy impact generated at the moment of airflow switching through the damping effect of a large number of micro channels, so that the airflow velocity blown towards the mushroom body is kept in the ideal range of 0.3-0.5m / s, providing a stable and mild wind field environment for the growth of mushroom primordia.

[0030] Fourth embodiment: Based on the above-described basic implementation, the present invention also provides a fourth embodiment, which specifically implements the sealing member 31 as a single-plate structure, as follows:

[0031] In this embodiment, the sealing component 31 is a first sealing plate 311, which moves linearly in the horizontal direction under the drive of the drive mechanism 32. The drive mechanism 32 includes a first drive motor 321 fixed on the bracket of the inner wall of the cabin 1. The first drive motor 321 is connected to the lead screw 322 through a coupling. A moving block 323 with internal threads is fitted on the lead screw 322. The moving block 323 is welded and fixed to the first sealing plate 311. In order to prevent the sealing plate from deflecting or shaking during the sliding process, two guide rods 324 are arranged parallel to the lead screw 322 inside the cabin 1. The sliding lug of the first sealing plate 311 is fitted on the guide rods 324.

[0032] The lead screw 322 is a trapezoidal lead screw with a self-locking function. The first drive motor 321 has the ability to rotate in both directions. With the feedback of the first position sensor 51 on the end of the stroke, it can ensure that the first sealing plate 311 is always pressed against the air outlet sealing strip with a constant pressure. Moreover, it can adjust the air outlet ratio of the low temperature air outlet 24 and the high temperature air outlet 25 by covering and blocking the area of ​​the low temperature air outlet 24 and the high temperature air outlet 25 as needed.

[0033] Fifth embodiment: Based on the above-described basic implementation methods, the present invention also provides a fifth embodiment, which specifically implements the sealing member 31 as a double-plate structure, as follows: In this design, the sealing component 31 includes two second sealing plates 312 forming a 90° angle with each other, each supported by two rotating shafts 313. The two rotating shafts 313 are rotatably connected to the inner walls of the cabin 1 on the sides adjacent to the low-temperature air outlet 24 and the high-temperature air outlet 25. The drive mechanism 32 uses gear transmission, including a central second gear 327 driven by a second drive motor 325, and two first gears 326 meshing with it on the left and right. When the second drive motor 325 drives the central second gear 327 to rotate, the two second sealing plates 312 rotate synchronously. Rotating in one direction, when one second sealing plate 312 rotates to a vertical 90° position, the other second sealing plate 312 seals one of the air outlets. At the rotating contact position, the edge of each second sealing plate 312 is covered with a U-shaped elastic sealing groove. When the second sealing plate 312 rotates to the horizontal position, the U-shaped groove is embedded in the edge step of the air outlet to form a seal. This structure has a fast switching speed, and at the same time, the second position sensor 52 ensures the synchronization of the two flip plate angles, preventing malfunctions such as the simultaneous opening or closing of the two air outlets.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
