Description

Technical Field

[0001] This utility model relates to the field of incubator technology, specifically a constant temperature incubator with a multi-layer structure. Background Technology

[0002] A constant temperature incubator is a laboratory device composed of a multi-layered chamber structure. It forms a closed-loop system through temperature sensors, controllers, and heating / cooling elements, combined with an air circulation device to achieve precise temperature control. It covers a variety of functions and is suitable for experiments in multiple fields such as biology, medicine, and agriculture. The multi-layered design can improve the efficiency of use. When using it, attention should be paid to environmental factors, cleanliness, and sample placement.

[0003] Existing constant temperature incubators require the entire door to be opened when a petri dish needs to be removed from a specific placement plate. This allows a large amount of cold air to enter the incubator, disrupting the temperature stability inside. This not only prolongs the time it takes for the temperature to return to the set value and increases energy consumption, but also may affect the culture effect of sensitive samples due to temperature fluctuations. Furthermore, the limited space in multi-layered constant temperature incubators makes it difficult to accurately retrieve the bottom petri dishes, increasing sampling difficulty and further exacerbating energy consumption. Therefore, we propose a constant temperature incubator with a multi-layered structure. Utility Model Content

[0004] The main objective of this invention is to provide a constant temperature incubator with a multi-layer structure, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature incubator with a multi-layer structure, including a constant temperature incubator body, an assembly cavity is provided in the inner cavity of the constant temperature incubator body, and a bearing component is slidably provided inside the assembly cavity. A servo motor is detachably nested at a corresponding position on the surface of the constant temperature incubator on the back of the bearing component. An adjusting screw is detachably connected to the power output end of the servo motor. A threaded connection hole is provided laterally at the center position of the lower end of the bearing component, and the bearing component is threaded to the surface of the adjusting screw through the threaded connection hole.

[0006] Preferably, the supporting component includes a sealing plate and a base plate. The base plate is slidably disposed inside the assembly cavity. The sealing plate is fixedly connected to both sides of the base plate. A snap-fit ​​component is provided on the inner side of the sealing plate, and a culture dish is detachably snapped onto the inner side of the snap-fit ​​component.

[0007] Preferably, the snap-fit ​​assembly includes a telescopic rod, a spring, and a clamping plate. The telescopic rod is detachably connected to the inner side of the sealing plate, and the clamping plate is detachably connected to the inner side wall of the telescopic rod. The spring is arranged around the surface of the telescopic rod, and the two ends of the spring abut against the sealing plate and the clamping plate, respectively.

[0008] Preferably, the shape of the sealing plate is adapted to the material inlet of the assembly cavity.

[0009] Preferably, the telescopic rods are in multiple sets and are horizontally arranged inside the sealing plate.

[0010] Preferably, the upper surface of the constant temperature incubator body is equipped with a control panel, and the servo motor is electrically connected to an external power source through the control panel.

[0011] Preferably, a fan is provided at the upper end of the inner cavity of the constant temperature incubator body, and a metal heating film is provided on the inner side of the inner cavity of the constant temperature incubator body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model utilizes a servo motor, adjusting screw, base plate, sealing plate, and threaded connection hole to work together. During loading and unloading, the servo motor drives the adjusting screw to rotate in both directions, which in turn drives the base plate, which is threaded to the adjusting screw through the threaded connection hole, and the sealing plates on both sides of the upper surface of the base plate to slide back and forth under the limitation of the assembly cavity. During unloading, the servo motor on the back of the corresponding assembly cavity is controlled to adjust and drive the base plate to rotate counterclockwise, causing the base plate to move the culture dish held above it outward. When it moves to the outermost position, the sealing plate on the upper inner side of the base plate will engage with the assembly cavity, thereby sealing the inlet. This prevents a large amount of cold air from entering the chamber during unloading, which would disrupt the temperature stability inside the constant temperature incubator. This solves the problem of large temperature fluctuations caused by opening the door of traditional incubators, which not only affects the cultivation effect but also increases energy consumption. It effectively provides a stable and reliable environmental guarantee for precision culture experiments.

[0014] 2. This utility model utilizes a base plate, a telescopic rod, a spring, a clamping plate, and a culture dish in cooperation. During feeding, the culture dish is placed between the clamping plates. Under the force of the spring, the telescopic rod will push the clamping plates inward, thereby clamping the culture dish above the base plate, thus achieving rapid feeding. When removing the material, push the clamping plates in the opposite direction to overcome the reaction force of the spring and quickly remove the culture dish. This allows for rapid feeding and can also be adapted to different sizes of culture dishes to a certain extent, effectively improving the practical effect of the device. Attached Figure Description

[0019] 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.

[0020] Example

[0021] Please see Figure 1 - Figure 3 The illustration shows a multi-layered constant temperature incubator, including an incubator body 1. An assembly cavity 3 is formed within the incubator body 1, and a support component 4 is slidably mounted inside the assembly cavity 3. A servo motor 5 is detachably nested at a corresponding position on the surface of the incubator on the back of the support component 4. An adjusting screw 6 is detachably connected to the power output end of the servo motor 5. A threaded connection hole 7 is laterally formed at the center of the lower end of the support component 4, and the support component 4 is threaded to the surface of the adjusting screw 6 through the threaded connection hole 7. When the servo motor 5 rotates in the forward or reverse direction, the adjusting screw 6 drives the support component 4 to slide precisely within the assembly cavity 3, achieving automatic insertion and removal of the culture dish 46. The entire process eliminates the need for manual operation within the incubator, avoiding temperature fluctuations caused by opening the door and ensuring the movement position through mechanical transmission. Compared to traditional manual push-pull structures, this effectively improves the automation and positioning accuracy of culture dish 46 storage and retrieval, facilitating operation and enhancing the practicality of the device.

[0022] The supporting component 4 includes a sealing plate 41 and a base plate 42. The base plate 42 is slidably disposed inside the assembly cavity 3. The sealing plate 41 is fixedly connected to both sides of the base plate 42. A snap-fit ​​component is provided on the inner side of the sealing plate 41, and a petri dish 46 is detachably snapped onto the inner side of the snap-fit ​​component. The snap-fit ​​component includes a telescopic rod 43, a spring 44, and a clamping plate 45. The telescopic rod 43 is detachably connected to the inner side of the sealing plate 41. The clamping plate 45 is detachably connected to the inner wall of the telescopic rod 43. The spring 44 is arranged around the surface of the telescopic rod 43, and the two ends of the spring 44 abut against the sealing plate 41 and the clamping plate 45, respectively. The sealing plate 41 is adapted to the material inlet of the assembly cavity 3. Multiple sets of telescopic rods 43 are horizontally arranged inside the sealing plate 41. The bottom plate 42 slides flexibly in the assembly cavity 3 to achieve precise positioning. The sealing plates 41 on both sides fit tightly with the material inlet of the assembly cavity 3, effectively isolating external interference when picking up and putting down the culture dish 46 and maintaining a constant temperature environment inside the chamber. The multiple sets of horizontally distributed telescopic rods 43 in the snap-fit ​​assembly, together with the spring 44 and the clamping plate 45, can not only adaptively clamp different sizes of culture dishes 46 through the elastic force of the spring 44 to ensure that the sample is stable and does not shake, but also can easily adjust the clamping force manually to achieve quick loading and unloading, improving the convenience of using the device.

[0023] The upper surface of the constant temperature incubator body 1 is equipped with a control panel 2, and the servo motor 5 is electrically connected to an external power source through the control panel 2. Experimenters can intuitively set the operating parameters of the servo motor 5 through the control panel 2, accurately control the moving distance and speed of the bearing component 4, and realize the precise adjustment of the storage and retrieval position of the culture dish 46. The operation is convenient and highly visual, effectively improving the practicality.

[0024] The constant temperature incubator body 1 is equipped with a fan at the upper end of its inner cavity and a metal heating film on the inner side of its inner cavity. Corresponding ventilation openings are located at both the upper and lower ends of the body. A temperature sensor is installed inside, allowing real-time monitoring of the internal temperature during incubation. The metal heating film (which uses a metal alloy or conductive ink as the heating layer, wrapped with insulating materials such as polyimide, efficiently converts electrical energy into heat energy based on Joule's law when current passes through it, achieving precise temperature control in conjunction with the temperature sensor and PID control algorithm, and transferring heat through infrared radiation, conduction, and convection; this technology is existing and will not be described in detail here) heats and controls the internal temperature. The fan drives airflow, ensuring uniform temperature within the chamber and preventing localized temperature differences from affecting the incubation results. This achieves precise and efficient temperature control, providing a stable and reliable environment for sample cultivation.

[0025] It should be noted that this utility model is a constant temperature incubator with a multi-layer structure. In use, the servo motor 5 is activated via the control panel 2, driving the adjusting screw 6 to rotate. This causes the bottom plate 42 and the two side sealing plates 41 to slide within the assembly cavity 3 to a position convenient for loading. The culture dish 46 is then placed between the clamping plates 45 above the bottom plate 42. Under the force of the spring 44, the telescopic rod 43 automatically pushes the clamping plates 45 inward, quickly fixing the culture dish 46. Subsequently, the servo motor 5 rotates in the opposite direction, causing the bottom plate 42 to return to its original position within the assembly cavity 3. At this point, the sealing plates 41 and the culture dish 46 are properly aligned. The feed inlet of assembly cavity 3 is locked and sealed. When removing the material, according to the position of the culture dish 46, the servo motor 5 on the back of the corresponding assembly cavity 3 is controlled by the control panel 2 to drive the adjusting screw 6 to rotate the base plate 42 counterclockwise and move it outward. When the base plate 42 moves to the outermost position, the sealing plate 41 engages with the assembly cavity 3 to prevent cold air from entering. At this time, the clamping plate 45 is pushed in the opposite direction to overcome the reaction force of the spring 44 and the culture dish 46 can be removed. This realizes convenient storage and retrieval of the culture dish 46, while effectively ensuring the stability of the temperature inside the chamber, reducing the cost of use, and improving the practical effect of the device.
