[0002] Currently, in microbial experiments, it is often necessary to treat samples such as petri dishes and culture media at a constant temperature or with programmed temperature rise to promote microbial growth or complete specific reactions. Existing heating equipment mostly uses a fixed heating structure, and the angle of the hot air or heat radiation outlet is not adjustable, resulting in uneven temperature distribution within the heating chamber, which affects the accuracy and repeatability of experimental results.

[0003] Existing heating devices are typically simple in structure and lack effective temperature monitoring and dynamic adjustment mechanisms. Especially in multi-point, multi-area heating scenarios, it is difficult to achieve real-time feedback on the internal temperature and adjust the airflow direction, which can easily lead to local overheating or heating blind spots, affecting the consistency of microbial culture and experimental efficiency.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] Example 1: This utility model provides a heating auxiliary device for microbial experiments, including a heating device body 1, an outer rotating plate 11 rotatably connected to the outer side wall of the heating device body 1, a control button 12 for controlling the device at the front end of the heating device body 1, and a placement platform 13 installed on the inner side of the heating device body 1 for heating microorganisms.

[0027] A heating assembly is disposed at the top and inside of the main body 1 of the heating device. The heating assembly includes a heating element. Multiple sets of heat transfer pipes 21 are installed on the outside of the heating element for transmitting heat energy. A heat transfer pipe 22 is installed at the bottom end of the heat transfer pipe 21 and is also installed on the inner wall of the main body 1 of the heating device. A heat outlet 23 is installed at the front end of the heat transfer pipe 22 for outputting heat energy.

[0028] An adjustment component is disposed on the inner wall and top of the heating device body 1, and the adjustment component includes a sensing module and a storage component.

[0029] During operation, the staff first starts the equipment by controlling button 12, places the petri dish on the placement platform 13 and closes the outer rotating plate 11 to form a sealed heating space; heat energy is generated by the heating component and delivered to each heat outlet 23 through the multi-channel heat energy transmission pipe 1 21 and heat energy transmission pipe 22; at the same time, the adjustment component monitors the internal environment in real time to prepare for uniform heating.

[0030] 1. In one embodiment of the present invention, the heating element is a heating pump 2, which is installed on the top of the heating equipment body 1 for connection with the heat energy transmission pipe 21 and supplying heat energy to the heat outlet 23 through the heat energy transmission pipe 21 and the heat energy transmission pipe 22.

[0031] During operation, the operator first starts the heating pump 2 by controlling button 12. The heating pump 2) serves as a centralized heat source, providing a stable and controllable heat energy output. The heat energy is distributed from the main heat energy transmission pipe 21 to the branch heat energy transmission pipes 22, and finally ejected from the heat outlet 23. This achieves efficient and reliable heat energy transmission from the central source to multiple dispersed outlets, laying the energy foundation for uniform heating of the cavity.

[0032] The heat pump unit 2 is a mature heat energy supply device in the prior art, and its working principle is usually based on resistance heating or compression heat pump cycle. For example, a conventional modular heat pump of model AP500 can be used, which converts electrical energy into heat energy through internal electric heating elements (such as PTC ceramic heaters or resistance wires), and the built-in fan drives the airflow to output hot air through pipes. This model and similar products are widely used in laboratory equipment, warm air drying, and other occasions. Their operating voltage (such as AC220V), power (such as 0-1500W adjustable), interface size, and temperature control interface all meet industrial standards and are common components known in the field. This utility model directly uses this existing mature component as the core heat source, and its structure and working principle are not the innovation of this patent.

[0033] 2. In one embodiment of the present invention, the sensing module includes a temperature detection module 33 and a control module 35. The temperature detection modules 33 are evenly installed in multiple locations in the corners of the inner wall of the heating device body 1. The multiple temperature detection modules 33 are connected in series with each other through transmission wires 34 and are installed together with the control module 35. The control module 35 is also installed on the top of the heating device body 1.

[0034] The temperature detection module 33 uses either the DS18B20 digital temperature sensor or the PT100 platinum resistance temperature sensor, both commonly used in existing technologies. Taking the DS18B20 as an example, it employs a single-bus protocol and can directly convert temperature values ​​into digital signal outputs. Its typical measurement accuracy is ±0.5℃, fully meeting the monitoring requirements of microbial experimental heating scenarios. The control module 35 can be a general-purpose embedded microcontroller module, such as a development board based on the STM32F103C8T6 chip or a temperature control unit within a PLC (Programmable Logic Controller) (e.g., the analog input / output module in Siemens S7-1200). These are all standardized, modular products readily available on the market. This invention utilizes existing sensors for multi-point temperature acquisition and receives and processes data through existing general-purpose control modules. The selection of these electrical components and their operation methods represent a direct application of existing technology.

[0035] The connecting motor 3 is a standard existing drive component, and can be a common small geared DC motor (such as model JGA25-370) or a stepper motor (such as model 28BYJ-48). This type of motor can be precisely controlled in terms of speed, direction, and rotation angle by receiving electrical signals (such as PWM pulses or high / low levels) from the control module 35. The motor drives the winding roller 31 to rotate via a coupling or direct drive. This is the most basic electromechanical conversion and control application, widely used in products such as curtain machines and cord reels, and the technology is very mature.

[0036] This invention simply applies the existing motor to perform simple wire take-up and unwinding actions.

[0037] During operation, the operator does not need to manually intervene. When the control module 35 determines that adjustment is needed based on the temperature data, it sends a command (such as a forward high-level signal that lasts for a certain period of time) to the connected motor 3 (such as JGA25-370). The control module 35 controls the existing model of the connected motor 3 to rotate forward or backward, driving the winding roller 31 to rotate, thereby realizing the winding or unwinding of the winding rope 32. The temperature adjustment decision is automatically converted into mechanical action, providing the core power and execution basis for remote and automatic adjustment of the angle of the heat outlet 23.

[0038] 3. In one embodiment of the present invention, the adjustment component includes a connecting motor 3, which is installed on the top of the heating device body 1. The connecting motor 3 is also connected to the control module 35 via wires. The output end of the connecting motor 3 is fixedly connected to a winding roller 31, and a winding rope 32 is wound around the outside of the winding roller 31.

[0039] During operation, the operator does not need to manually intervene. When the control module 35 determines that adjustment is needed based on the temperature data, it sends a command to the connecting motor 3. The control module 35 controls the connecting motor 3 to rotate forward or backward, driving the winding roller 31 to rotate, thereby realizing the winding or unwinding of the winding rope 32. The decision to adjust the temperature is automatically converted into mechanical action, providing the core power and execution basis for remote and automatic adjustment of the angle of the heat outlet 23, and realizing intelligent control.

[0040] 4. In one embodiment of the present invention, a plurality of support frames 26 are fixedly connected to the inner side wall of the heating device body 1. The number of support frames 26 is the same as the number of heat outlets 23 and they are installed on the top of the heat outlets 23 for adjusting the angle of the heat outlets 23. The bottom end of the support frame 26 is fixedly connected to a limiting collar 27. The bottom of the second winding rope 32 is fixedly connected to a plurality of first winding ropes 25. The plurality of first winding ropes 25 are also slidably connected to the outer side wall of the limiting collar 27.

[0041] During operation, the operator first uses the motor 3 to move the winding rope 2 32. The up-and-down movement of the winding rope 2 32 drives the multiple winding ropes 1 25 connected to its bottom to move synchronously. The limiting collar 27 restricts the movement path of the winding ropes 1 25 to the vertical direction, ensuring that the force applied to the heat outlet 23 is a vertical upward pulling force. This efficiently and accurately converts the rotational motion of the winding roller into a lifting action on the heat outlet 23, providing a stable and reliable transmission mechanism for flexible angle adjustment.

[0042] 5. In one embodiment of the present invention, a suspension head 24 is fixedly connected to the bottom end of the winding rope 25. The suspension head 24 is ring-shaped and sleeved on the outer side wall of the heat outlet 23 for adjusting the angle of the heat outlet 23. A bottom limiting plate 28 is fixedly connected to the inner side wall of the heating device body 1 for supporting the winding rope 25.

[0043] During operation, the operator first controls the movement by lifting or loosening the winding rope 25. The suspension head 24, with its annular structure, is positioned outside the heat outlet 23. When the winding rope 25 is lifted vertically, the suspension head 24 pulls the tail of the heat outlet 23 upwards, causing the airflow direction to change from horizontal to downward tilt. When the rope is loosened, the heat outlet 23 returns to its original position under its own weight, achieving an upward tilt, thus flexibly changing the angle of the hot air jet. The bottom limiting plate 28 provides lower limit support for the winding rope 25, preventing excessive slack and swaying, ensuring the stability and accuracy of the angle adjustment process, and ultimately achieving precise airflow to different areas within the heating chamber, effectively balancing the temperature.

[0044] Working principle: When this device is needed, first open the outer rotating plate 11, then place the petri dish to be heated on the placement platform 13. Next, close the outer rotating plate 11 and control the heating pump 2 through the control button 12. The heating pump 2 will deliver heat energy to the heat outlet 23 through the heat transfer pipe 1 21 and the heat transfer pipe 22. The heat energy is sprayed into the heating device body 1 through the heat outlet 23, so that the interior of the heating device body 1 is heated evenly. The temperature detection module 33 can detect the temperature inside the heating device body 1 evenly. If the temperature is uneven, the temperature detection result will be transmitted to the control module 35 through the transmission wire 34. The control module 35 will control the connecting motor 3 to work. The connecting motor 3 will rotate the winding roller 31 and the winding rope 2 32 to wind or unwind. The winding rope 2 32 will adjust the elevation or depression angle of the heat outlet 23 with the winding rope 1 25 and the suspension head 24 to change the temperature transmission angle and make the internal temperature more uniform.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
