[0001] This utility model relates to the field of food testing technology, and in particular to an incubator for food testing. Background Technology

[0002] As people's living standards continue to improve, food safety issues are receiving increasing attention. Among the many food safety-related projects, contamination caused by microorganisms and their various toxins is of great concern. The hazards of foodborne microorganisms have always been one of the focal points of food safety concerns, and therefore, microbial testing is usually conducted on food.

[0003] As a core device for holding test reagents and providing a stable culture environment, the incubator's effectiveness in fixing the reagents directly affects the accuracy and reliability of the test results. Existing food testing incubators often suffer from reagent movement during storage due to their overly simplistic storage openings and uniformly sized holes, leading to potential reagent contamination or reaction failure caused by design flaws in the fixing structure. Therefore, this paper proposes an incubator for food testing to address these issues. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a food testing incubator, comprising a test chamber 1. A control box 2 is fixedly connected to the bottom of the test chamber 1, integrating drive components and a temperature control module to provide operational support for the incubator. A metal door 3 is rotatably connected to the front of the test chamber 1, sealing the internal space of the test chamber 1 to maintain a stable culture environment in conjunction with the temperature control system, while also facilitating operation by testing personnel. A temperature controller 4 is installed on the front of the control box 2, precisely regulating the internal temperature of the incubator to meet the culture temperature requirements of different food testing reagents. A motor 5 is fixedly connected inside the control box 2, serving as a power source. The motor 5 drives a rotating disk via a drive shaft, automating the rotation and placement of multi-layer culture reagents. A rotating shaft 6 is detachably connected to the drive end of the motor 5, transmitting motor power. Its detachable design facilitates equipment maintenance and component replacement. The external rotating shaft 6 is rotatably connected to the top center of the control box 2, supported by bearings and other rotating structures to ensure smooth rotation and reduce power transmission loss. A second rotating shaft 7 is detachably connected to the top of rotating shaft 6. Rotating shaft 7 expands the vertical space of the incubator, increasing the storage capacity of culture reagents through layered stacking. A third rotating shaft 8 is detachably connected to the top of rotating shaft 7, further extending the height of the incubator and forming a three-dimensional storage structure with the multi-layered turntables, improving space utilization. Turntables 9 are fixedly connected to the exterior of rotating shafts 6, 7, and 8. Turntables 9 hold culture reagents, and their rotational design facilitates quick positioning of target reagents by testing personnel. Multiple slide rail bases 10 are fixedly connected to the top of turntables 9. The slide rail bases 10 provide the mounting base for the rotating bar and circular clamping module, while also defining the sliding trajectory of the clamping module. Holes 11 are provided at the top of rotating shafts 6 and 7. Holes 11 cooperate with pressing caps to form a detachable connection structure between the rotating shafts, facilitating quick assembly and disassembly of the layered components. Both the second rotating shaft 7 and the third rotating shaft 8 have grooves 12 at their bottom ends. The grooves 12 are used to accommodate the first spring and the pressing cap, providing space for the elastic locking of the rotating shaft connection. The pressing caps 13 are slidably connected to both sides of the grooves 12. The pressing caps 13 lock the rotating shafts by sliding into the holes 11. The locking can be released by pressing, making the operation convenient.

[0032] Reference Figures 3-5The outer side of the pressing cap 13 is inserted into the inside of the hole 11, and the relative position of the rotating shaft is fixed by mechanical cooperation to ensure the stability of the hierarchical structure when the turntable rotates. A spring 14 is fixedly connected to one side of each of the two pressing caps 13. Spring 14 provides a reset force to keep the pressing caps locked and prevent the rotating shaft from accidentally falling off. Spring 14 is located inside the groove 12 and achieves sliding control of the pressing caps through compression and extension. The structure is compact and highly reliable. A fixed shaft 15 is fixedly connected to the middle of the slide rail base 10. The fixed shaft 15 serves as the rotation fulcrum of the rotating bars, allowing the two rotating bars to rotate around it, forming the power transmission center of the clamping mechanism. Two rotating bars 16 are rotatably connected to the outside of the fixed shaft 15. The two rotating bars 16 are distributed in an X-shape, and the opening and closing action of the circular clamping module is achieved through cross rotation. The structure is simple and the transmission efficiency is high. A spring 2 17 is fixedly connected between the opposite sides of the two rotating bars 16. Spring 2 17 provides clamping force. When the rotating bars reset, it drives the circular clamping module to clamp the culture reagent and prevent shaking. A second spring 17 is fixedly connected to the top of the rotating bar 16. This spring connection enhances the stability of the rotating bar's reset and ensures uniform clamping force. A circular clamping module 18 is slidably connected to the top of the slide rail base 10. The circular clamping module 18 carries the culture reagent, and its sliding design works in conjunction with the rotating bar's movement to achieve automatic clamping and release. A sliding groove 19 is provided at the bottom of the circular clamping module 18, providing a sliding track for the end of the rotating bar, guiding its movement trajectory and ensuring precise and reliable clamping. Both ends of the rotating bar 16 are slidably connected to the inner wall of the sliding groove 19. Through mechanical cooperation, the rotational motion of the rotating bar is converted into the horizontal sliding of the circular clamping module, achieving the clamping function. The second spring 17 is located inside the sliding groove 19, storing elastic force in a compressed state. When the rotating bar resets, it releases energy to drive the circular clamping module to clamp the culture reagent in the center.

[0033] Working Principle: When food testing is required, the corresponding set of circular clamping modules 18 is pulled open, and the culture reagent for food testing is placed into the circular clamping module 18. After placement, due to the elasticity of spring 2 17, spring 2 17 will drive the rotating bar 16 to reset. At this time, the rotating bar 16 simultaneously drives the sliding groove 19 to center and firmly clamp the culture reagent, effectively preventing the culture reagent from shaking. When the culture reagent needs to be removed, the tester can rotate each turntable 9 to remove multiple different reagents. Alternatively, when the tester needs to remove the same batch of culture reagents, the tester can select one reagent to be removed, and then press the pressing caps 13 on both sides of the bottom of the rotating shaft 2 7 or rotating shaft 3 8 to make the pressing caps 13 squeeze the spring 14 in the middle and retract it into the groove 12, thereby achieving the effect of disassembling rotating shaft 1 6 and rotating shaft 2 7 or rotating shaft 2 7 and rotating shaft 3 8. This greatly facilitates the tester in removing culture reagents and makes it easier for the tester to clean the inside of the incubator, effectively increasing work efficiency.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
