Description

Technical Field

[0001] This utility model relates to the field of cell culture technology, and in particular to a constant temperature box. Background Technology

[0002] An incubator is a widely used device in biology, chemistry, and medicine to provide a stable temperature environment for experimental samples. Typically, an incubator is a relatively sealed device that heats its internal environment by blowing in hot air, and a precision motor is controlled to rotate evenly within the internal environment to achieve the desired cell or culture medium activity. This relates to the field of cell culture technology.

[0003] Existing incubators typically employ an open design, possessing only basic shaking functionality and lacking the ability to independently control the temperature of the culture environment. They usually utilize static heating, controlling the internal temperature of the chamber through heating elements. However, this heating method easily leads to uneven temperature distribution within the chamber, especially when multiple samples need to be treated at the same temperature simultaneously, making it difficult to ensure that each sample is under identical temperature conditions. Furthermore, CO2 incubators have limited internal space, particularly in laboratory environments. If a shaker is placed inside to maintain the temperature control environment, a large portion of the incubator space will be occupied, resulting in wasted resources. Existing shakers mostly use mechanical knobs to adjust the speed, which suffers from poor adjustment precision and repeatability, making it difficult to maintain consistent experimental conditions across different batches, directly affecting the reliability and reproducibility of experimental data.

[0026] An incubator is a widely used device in biology, chemistry, and medicine to provide a stable temperature environment for experimental samples. Typically, an incubator is a relatively sealed device that heats its internal environment by blowing in hot air, and a precision motor is controlled to rotate evenly within the internal environment to achieve the desired cell or culture medium activity. This relates to the field of cell culture technology.

[0027] Existing incubators typically employ an open design, possessing only basic shaking functionality and lacking the ability to independently control the temperature of the culture environment. They usually utilize static heating, controlling the internal temperature through heating elements. However, this heating method easily leads to uneven temperature distribution within the chamber, especially when multiple samples need to be treated at the same temperature simultaneously, making it difficult to ensure that each sample is under identical temperature conditions. Furthermore, CO2 incubators have limited internal space, particularly in laboratory environments. If a shaker is placed inside to maintain the temperature control environment, a large portion of the incubator space is occupied, resulting in wasted resources. Existing shakers mostly use mechanical knobs to adjust the rotation speed, which suffers from poor adjustment precision and repeatability, making it difficult to maintain consistent experimental conditions across different batches, directly impacting the reliability and reproducibility of experimental data. Therefore, there is an urgent need for an incubator that can ensure a constant internal temperature and uniform, controllable rotation speed.

[0028] See Figures 1-3To address the aforementioned problems, this utility model application provides a constant temperature chamber 10, which can be used in the field of cell culture technology to provide a stable temperature environment for experimental samples. The constant temperature chamber 10 includes a housing 20, a door panel 30, a main control board, a rotating assembly 40, and a hot air assembly. The housing 20 serves as the outer shell of the constant temperature chamber 10, separating its internal structure from the outside environment. In some embodiments, the constant temperature chamber 10 may have a cuboid structure. The housing 20 may be made of high-strength engineering plastics or metal, providing good thermal insulation and corrosion resistance to ensure long-term stable operation of the constant temperature chamber 10. A constant temperature chamber 21 is provided inside the housing 20, which is used to place experimental samples, such as centrifuge tubes 60 and test tubes. The constant temperature chamber 21 has good sealing properties to reduce temperature fluctuations within it. The door panel 30 can be designed to be openable and closable, allowing it to be installed on the housing 20 for easy sample access. For example, a torque hinge can be used, with one end connected to the shaker housing 20 and the other end connected to the door panel 30. The torque of the hinge can be manually adjusted to change the flipping force of the door panel 30. When closed, it fits tightly against the housing 20 to prevent heat loss. The rotating assembly 40 is rotatably connected to the wall 211 of the constant temperature chamber 21. The rotating assembly 40 is used to hold the centrifuge tubes 60. Specifically, the rotating assembly 40 can be a rotatable support, which can fix the experimental container, such as the centrifuge tubes 60, to ensure that the sample is heated evenly under constant temperature conditions. The rotation speed of the rotating assembly 40 can be adjusted according to experimental needs, so that the constant temperature chamber 10 can be used in experimental scenarios with different rotation speed requirements. An installation cavity is provided inside the housing 20, and a spacer is formed between the constant temperature cavity 21 and the installation cavity. The hot air assembly is located in the installation cavity and is connected to the constant temperature cavity 21, which can prevent the heat source from directly contacting the experimental sample and improve the uniformity of temperature control. The rotating assembly 40 and the hot air assembly are electrically connected to the main control board, which is responsible for the temperature regulation, speed control and safety monitoring of the whole machine to ensure stable operation of the equipment.

[0029] Furthermore, to facilitate user adjustment of parameters such as the internal temperature of the incubator 10 according to their needs, a touch panel 241 is installed on the outer wall 24 of the housing 20. The touch panel 241 can adopt high-sensitivity capacitive touch technology and is integrated in a prominent position on the outer wall 24 of the housing 20. Users can directly control the incubator 10 by touching the touch panel 241. The touch panel 241 is electrically connected to the main control board, which is responsible for the temperature regulation, speed control, and safety monitoring of the entire machine to ensure stable operation of the equipment. In some embodiments, the touch panel 241 can adopt an arc-shaped curved surface structure. Specifically, it can be a tempered glass panel with an arc-shaped curved surface. The surface of the tempered glass panel can be coated with an anti-fingerprint coating, which can improve the aesthetics of the incubator 10 and enhance the user experience. The touchpad 241 can be embedded into the outer wall 24 of the housing 20. An edge silicone sealing ring can be provided at the contact surface between the touchpad 241 and the outer wall 24 of the housing 20 to improve the waterproofness of the incubator 10. In some embodiments, the touch system incorporates a micro-vibration motor to provide tactile feedback, supports pressure sensing and glove operation modes, and also features ambient light adaptation and night mode switching functions.

[0030] Furthermore, the hot air assembly includes a heater and a fan. The heater rests against the inner cavity, and the fan continuously blows hot air into the inner cavity to raise its temperature. The heater and fan are electrically connected to the main control board to achieve intelligent temperature control management. The heater can use a high-efficiency electric heating element, which can quickly heat up and maintain a stable output. Its installation position is flexible, typically fixed to the inner wall of the constant temperature cavity 21 or the wall of an independently mounted cavity, ensuring uniform heat diffusion. The heater is located on the fan's outlet side, allowing the airflow to enter the constant temperature cavity 21 directly after heating, reducing heat loss. The fan ensures smooth hot air circulation, preventing uneven temperature distribution within the constant temperature cavity 21. Simultaneously, the fan works in conjunction with the heater, forcing airflow to improve heat exchange efficiency and shorten temperature adjustment time. In use, the user can control the heater's operation according to the set temperature parameters by adjusting the main control board, while simultaneously adjusting the fan speed. The fan pushes air to the heating area, and the heated airflow enters the constant temperature cavity 21 through the air duct, forming circulating hot air, allowing the cavity temperature to quickly reach and maintain the set value. At this time, temperature sensor 221 monitors the environment inside the cavity in real time, and the main control board dynamically adjusts the heating power and fan speed to ensure accurate and stable temperature control.

[0031] The thermostatic chamber 10 and the mounting cavity are divided into two independent spaces using a partitioned structure. The thermostatic chamber 10 and the mounting cavity are connected by a hot air window 50 to form a complete hot air circulation path. The hot air window 50 ensures smooth airflow. In some embodiments, the surface of the hot air window 50 is covered with a high-temperature resistant material to give it excellent high-temperature resistance. The heater can be directly fixed to the hot air window 50 using an embedded installation method, ensuring efficient heat transfer. The fan is located inside the mounting cavity, maintaining a reasonable distance from the hot air window 50 to ensure stable and reliable operation. During operation, the fan generates airflow during startup, and air flows from the mounting cavity to the hot air window 50. Further, during the heating phase, the airflow passes through the heater at the window and is rapidly and evenly heated. During circulation, the hot air enters the thermostatic chamber 21 through the window to complete temperature regulation before returning. Throughout this process, the heater is directly located in the airflow channel, reducing heat loss, and the scientifically designed airflow path ensures temperature consistency within the cavity.

[0032] In some embodiments, the housing 20 is provided with a magnetic suction component 25, which is used to attract and fix the door panel 30. The magnetic suction component 25 has an automatic attraction function; when the door panel 30 approaches the closed position, the magnetic force automatically applies to ensure that the door panel 30 fits tightly. The magnetic suction design can avoid the wear problem of traditional mechanical locks and extend the service life of the constant temperature chamber 10. Specifically, the magnetic suction component 25 is electrically connected to the main control board, which can display the closing status of the door panel 30 in real time to improve the convenience of user operation. At the same time, the magnetic suction component 25 can provide uniform magnetic attraction between the housing 20 and the door panel 30 to ensure the complete sealing of the constant temperature chamber 21. In some embodiments, the constant temperature chamber 21 is provided with an ultraviolet lamp assembly 212, which has a disinfection function to ensure a sterile working environment. Specifically, the ultraviolet lamp tube can be made of quartz glass, which has high light transmittance. Alternatively, high borosilicate glass can be used, which is more cost-effective than quartz glass. The interior of the ultraviolet lamp is filled with low-pressure mercury vapor. The ultraviolet light source can use a chip made of materials such as gallium nitride as the light-emitting core, which generates ultraviolet light through electrode excitation. The magnetic component 25 and the ultraviolet lamp assembly 212 can cooperate with each other. Specifically, the magnetic component 25 is fixed to the housing 20, and its engagement can be controlled by power off or on. When the internal ultraviolet lamp assembly 212 is turned on, to protect the eyes, the magnetic component 25 will firmly hold the housing 20, preventing the door from opening.

[0033] In some embodiments, the constant temperature chamber 21 and the mounting chamber are arranged side by side and separated by a heat-insulating partition. The independent space of the constant temperature chamber 21 and the mounting chamber can prevent the components inside the constant temperature chamber 10 from being affected by temperature. The housing 20 is provided with a detachable side plate 26, which is connected to the side of the mounting chamber away from the constant temperature chamber 21. The side plate 26 can adopt a snap-fit ​​structure for easy installation and disassembly. The side plate 26 protects the constant temperature chamber 21. The side plate 26 and the housing 20 can also be fixed with screws. When maintenance is required, the side plate 26 can be removed to inspect and maintain the inside of the constant temperature chamber 10. In some embodiments, the inner side of the side plate 26 is provided with a dustproof sealing strip to ensure the airtightness of the cavity.

[0034] When using the incubator 10, cells or culture medium can be placed on the rotating assembly 40. Specifically, the rotating assembly 40 includes a motor 41, a mounting bracket 42, and bearings 43. The motor 41 serves as the power source for the rotating assembly 40 and can be a brushless DC motor. Specifically, the motor 41 is mounted on a motor mount and connected to the main control board. In some embodiments, the motor 41 can be equipped with overload protection and temperature monitoring functions. In one embodiment, the motor is a brushless motor with a control voltage of 12V or 24V. The motor speed is adjustable, achieving a minimum of 1 rpm and a maximum of 200 rpm. The mounting bracket 42 is used to hold centrifuge tubes 60. The mounting bracket 42 can be made of stainless steel for easy cleaning and sterilization. The mounting bracket 42 can have a multi-hole design to accommodate multiple centrifuge tubes 60. In some implementations, multiple centrifuge tubes 60 of different sizes need to be placed on the mounting bracket 42. For example, in a certain experiment, 5ml centrifuge tubes 60, 10ml centrifuge tubes 60, and 15ml centrifuge tubes 60 need to be placed. Since the diameters of the centrifuge tubes 60 vary with their capacities, replaceable mounting brackets 42 can be provided to accommodate combinations of centrifuge tubes 60 of different capacities, making the incubator 10 suitable for more experimental scenarios. The mounting bracket 42 can be made of plastic or metal. In some embodiments, the surface of the mounting bracket 42 is treated with an anti-slip coating and is equipped with slots or clamps to accommodate different tube diameters, ensuring that the centrifuge tubes 60 do not shift or fall off during high-speed rotation. The overall structure of the mounting bracket 42 is dynamically balanced to effectively reduce vibration during operation. The bearing 43 forms a stable support with the inner wall of the incubator 21. Specifically, the bearing 43 is installed on the section of the mounting bracket 42 away from the motor 41. The structure of the motor 41 drive combined with the bearing 43 support significantly improves the overall rigidity and operational stability of the rotating assembly 40. In some embodiments, the bearing 43 can be made of a high-temperature resistant, low-friction coefficient material to ensure long-term stability under constant temperature conditions. In some embodiments, the connection between the motor 41 and the mounting bracket 42 can be equipped with a protective cover to prevent foreign objects from entering, and the bearing 43 adopts a sealed structure to effectively prevent moisture or chemical corrosion within the constant temperature chamber 21. The motor 41 is electrically connected to the main control board, which can monitor the operating status of the motor 41 in real time and automatically shut down for protection in case of abnormalities, ensuring experimental safety.

[0035] In some embodiments, the rotation axis of the mounting bracket 42 is parallel to the arrangement direction of the constant temperature chamber 21 and the mounting cavity. This parallel arrangement effectively utilizes the internal space of the constant temperature chamber 10, allowing the hot airflow within the constant temperature chamber 21 to flow evenly around the mounting bracket 42, ensuring uniform heating of the centrifuge tubes 60. Regarding structural stability, the parallel arrangement of the rotation axis makes the force on the support points at both ends of the mounting bracket 42 more balanced. The supporting forces at the motor end 41 and the bearing end 43 are distributed along the same axis, effectively reducing vibration and swaying during operation and ensuring the stability of the centrifuge tubes 60 during rotation. This design is suitable for experiments requiring long-term stable operation. Simultaneously, this layout allows the motor 41 and other drive components to be rationally placed within the mounting cavity, ensuring both power transmission efficiency and ease of daily maintenance. The parallel design of the rotation axis also brings operational convenience. For example, when the user opens the door panel 30 to access the centrifuge tubes 60, the axial direction of the mounting bracket 42 is consistent with the operating direction, making the retrieval and placement actions more natural and smooth.

[0036] In some embodiments, the constant temperature chamber 21 is equipped with multiple sets of rotating components 40, each with a parallel rotation axis. These multiple sets of parallel rotating devices significantly improve the sample processing capacity and experimental efficiency of the equipment. The multi-axis parallel layout design fully considers the convenience of experimental operation and the guarantee of temperature uniformity. Specifically, the multiple sets of rotating components 40 arranged side-by-side within the constant temperature chamber 21 adopt identical structural standards, each including an independent mounting bracket 42, a drive motor 41, and a support bearing 43. The rotation axes of all rotating components 40 maintain a strict parallel relationship. This symmetrical layout not only makes full use of the internal space of the equipment but also ensures synchronous processing of samples under the same conditions. Each rotating component 40 can operate independently or work collaboratively to meet the needs of experiments of different scales. Simultaneously, the parallel multi-rotating-axis structure allows the hot air assembly to evenly cover all rotating components 40, ensuring that each centrifuge tube 60 receives a consistent temperature control environment. The hot air flows smoothly along the parallel axes, avoiding temperature dead zones and making the temperature distribution within the constant temperature chamber 21 more uniform and stable.

[0037] To achieve high-precision temperature monitoring of the constant temperature chamber 10, a temperature sensor 221 is installed inside the mounting cavity. The probe of the temperature sensor 221 extends into the constant temperature chamber 21, enabling it to accurately sense the actual temperature within the chamber. For example, the temperature probe can be a strip-shaped metal rod. Inserting its probe portion into the mounting cavity allows for real-time detection of changes in the internal ambient temperature, which is then fed back to the integrated control unit for temperature control. The probe can be made of high-temperature resistant and corrosion-resistant materials to ensure stable temperature measurement performance during long-term use. The temperature sensor 221 is electrically connected to the main control board. The main control board receives the real-time temperature data collected by the sensor, processes it through an intelligent algorithm, and automatically adjusts the operating parameters of the heating system and fan to maintain the temperature of the constant temperature chamber 21 within the set range. The system has a temperature abnormality alarm function. When the temperature exceeds the safe range, the protection mechanism is automatically activated to enable the constant temperature chamber 10 to monitor its temperature, allowing users to easily monitor the equipment's operating status.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
