[0016] This invention adds a novel anti-static interference device to the top of the control box of a constant temperature cell culture incubator. This device, through two types of nozzles at the bottom of the gas collecting pipe, forms a dual-directional ion delivery path: a downward airflow from the front of the control box plus a forward-tilted 45° airflow. This addresses static electricity hazards in different areas. The downward airflow directly guides the ion flow to the controller, display screen, and control button area at the front of the control box, quickly neutralizing static electricity generated by frequent human operation (such as pressing control buttons or touching the display screen) or environmental friction. This prevents static interference with controller signal transmission and damage to electronic components, ensuring stable operation of the equipment interface. The forward-tilted 45° nozzle precisely delivers the ion flow to the door and the front of the culture chamber, preemptively neutralizing static electricity generated when the door is opened and closed. This prevents static electricity from attracting dust particles from the air and preventing dust from entering the culture chamber when the door is opened. Simultaneously, it eliminates static interference with precision sensors such as temperature and humidity sensors inside the culture chamber, providing dual protection for equipment operation and a clean and stable cell culture environment.

Description
Technical Field
[0001] This utility model belongs to the field of biomedical engineering technology, specifically relating to a constant temperature cell culture incubator. Background Technology
[0002] Thermostatic cell culture incubators are core equipment in the fields of biological experiments and biomedicine. Through the power supply and control support provided by the component chassis, combined with the internal heating box, external valves (connecting humidity / gas / ventilation modules), and culture placement plates, the temperature, humidity, and gas composition (such as CO2 concentration) inside the incubator can be precisely controlled to provide a stable and clean thermostatic culture environment for cell growth and reproduction. They are widely used in cell biology research, vaccine preparation, drug screening, and other scenarios, and are key equipment to ensure the accuracy of experimental results and the stability of the production process.
[0003] However, existing constant-temperature cell culture incubators are susceptible to static electricity issues during actual use due to the usage scenarios and equipment structure characteristics. On the one hand, the control panel at the front of the incubator is a high-frequency operating area for experimenters. Frequent contact and friction between personnel's hands and control buttons and displays, as well as friction between personnel's clothing and the equipment casing in dry environments, easily accumulate static electricity on the surface of the control panel. This static electricity may not only interfere with the signal transmission of the controller, causing deviations in the control of parameters such as temperature and humidity, but may also damage precision electronic components such as displays, shortening the service life of the equipment. On the other hand, during the opening and closing of the incubator door, friction between the door and the cabinet, the deformation of the door seal, and the charge transfer when personnel touch the door can easily generate static electricity on the door surface. Static electricity attracts dust particles from the air, and when the door is opened, this dust-laden static electricity can easily bring dust into the incubator, contaminating the cell culture environment, affecting cell growth, and even causing experimental failure. At the same time, static electricity near the door may also interfere with the temperature and humidity sensors inside the incubator, leading to inaccurate environmental parameter detection and further compromising culture stability.

[0009] Preferably, the anti-static interference device further includes a gas collecting pipe and a conveying pipe. The conveying pipes are fixed longitudinally on both the left and right sides of the center of the front end of the ion generator. The front ends of the two conveying pipes are connected to the gas collecting pipe, and the ion generator is connected to the inside of the gas collecting pipe through the conveying pipe. The gas collecting pipe is located laterally on the upper front side of the control top box.
[0010] Preferably, the anti-static interference device further includes multiple nozzles. Multiple nozzles are equidistantly arranged at the bottom of the air collecting pipe. The multiple nozzles are an equal number of inclined nozzles and vertical nozzles, and the multiple inclined nozzles and multiple vertical nozzles are staggered with each other.

[0015] Compared with the prior art, this utility model provides a constant temperature cell culture incubator, which has the following beneficial effects:
[0016] This invention adds a novel anti-static interference device to the top of the control box of a constant temperature cell culture incubator. This device, through two types of nozzles at the bottom of the gas collecting pipe, forms a dual-directional ion delivery path: a downward airflow from the front of the control box plus a forward-tilted 45° airflow. This addresses static electricity hazards in different areas. The downward airflow directly guides the ion flow to the controller, display screen, and control button area at the front of the control box, quickly neutralizing static electricity generated by frequent human operation (such as pressing control buttons or touching the display screen) or environmental friction. This prevents static interference with controller signal transmission and damage to electronic components, ensuring stable operation of the equipment interface. The forward-tilted 45° nozzle precisely delivers the ion flow to the door and the front of the culture chamber, preemptively neutralizing static electricity generated when the door is opened and closed. This prevents static electricity from attracting dust particles from the air and preventing dust from entering the culture chamber when the door is opened. Simultaneously, it eliminates static interference with precision sensors such as temperature and humidity sensors inside the culture chamber, providing dual protection for equipment operation and a clean and stable cell culture environment.
[0017] The ion generator and small blower of this device are electrically linked to the control top box via an induction control switch. It can automatically trigger directional blowing according to the actual operating scenario. When the experimenter approaches the control top box operation buttons (triggers downward blowing), or reaches out to open or close the box door (triggers forward tilting 45° blowing), the induction control switch can activate the device in real time, delivering ions through the corresponding nozzles to quickly eliminate static electricity generated during operation. When not in use, the device automatically goes into standby mode, avoiding energy waste caused by continuous downward or forward blowing and preventing excess airflow from interfering with the microenvironment around the incubator. This balances convenience and energy efficiency. Furthermore, the directional blowing design, while eliminating static electricity, can also drive ion flow through airflow, reducing the ability of static electricity to attract dust particles. Downward blowing can clean the surface of the control top box operation panel of small amounts of dust, preventing dust accumulation from affecting button sensitivity or display screen clarity. Forward tilting 45° blowing can neutralize static electricity on the door before it is opened, preventing dust attracted to the door from entering the incubator with the opening action, indirectly reducing the risk of cell culture contamination.

Detailed Implementation
[0023] 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.
[0024] This utility model provides, for example Figure 1-4 The illustrated constant-temperature cell culture chamber includes a component housing 1 and a culture chamber body 8 mounted on top of the component housing 1. The component housing 1 provides stable support for the culture chamber body 8 and can also house core components such as power supply and control systems to ensure the overall operation of the equipment. The front end of the culture chamber body 8 is open for easy access to cell culture containers. A control top box 3 is located at the top of the culture chamber body 8, serving as the central hub for equipment operation and control. It can integrate various control components. A controller 4 is located inside the front end of the control top box 3. The controller 4 is the brain of the equipment, responsible for receiving and processing various signals. The front end of the controller 4 is equipped with a display screen and multiple control buttons. The display screen can intuitively display parameters such as temperature and humidity inside the culture chamber, while the control buttons allow for manual adjustment by the experimenter. The system enables human-computer interaction. Multiple external valves 6 are located at the rear of the top center of the control box 3, and all of these valves 6 are connected to the interior of the culture chamber 8. This design keeps the external valves 6 away from the front operating area, preventing accidental activation during operation. These external valves 6 can be connected to external humidity control modules, gas control modules, and ventilation control modules. The working principle is that the external modules deliver regulating media (such as humidifying gas or CO2) to the interior of the culture chamber 8 or expel internal gas through the external valves 6, thereby precisely controlling the humidity, gas content, and ventilation inside the culture chamber 8 to meet the specific environmental requirements of cell culture. The advantage of this design is its flexibility in adapting to different culture scenarios, improving environmental control precision through external professional modules, and eliminating the need for complex modifications to the culture chamber 8 itself.
[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the incubator 8 has a door 2 at its front end. The door 2 is rotatably connected to the left end of the incubator 8 via multiple hinges. The advantage of hinge connection is its simple structure and smooth opening and closing, making it easy for experimenters to open the door 2. At the same time, it can ensure the stability of the door 2 when opening and closing, avoiding fluctuations in the internal environment caused by shaking. A magnetic sealing gasket 7 is also fixed to the outer wall of the rear end of the door 2. After the door 2 is completely closed at the front end of the incubator 8, the magnetic sealing gasket 7 can be magnetically attracted and attached to the outer wall of the front end of the incubator 8. Its sealing principle is that the magnetic sealing gasket 7 uses magnetic attraction to tightly adhere to the front end of the incubator 8. At the same time, the elastic material of the sealing gasket itself can fill the gap between the door 2 and the incubator 8, effectively preventing the leakage of constant temperature and humidity gas inside the incubator 8, and also preventing the entry of external air and dust, ensuring the stability of the internal environment. Compared with traditional rubber seals, the magnetic design has a more durable sealing effect, and there is no need to overcome excessive friction when opening and closing, making it more convenient to use.
[0026] like Figure 1 , Figure 2 and Figure 3As shown, a set of fixed supports 11 is provided on the inner walls of both the left and right ends of the culture chamber 8. A culture placement plate 10 is connected between the two sets of fixed supports 11. The fixed supports 11 provide stable support for the culture placement plate 10 and can adjust the installation position of the culture placement plate 10 according to the height of the culture container, thereby improving space utilization. The culture placement plate 10 has equidistantly spaced ventilation holes inside. The ventilation principle is that the holes allow the airflow, temperature, humidity and other environmental factors inside the culture chamber 8 to be evenly distributed in each layer of the culture space, avoiding environmental differences between upper and lower layers due to the obstruction of the culture placement plate 10, ensuring that all cell culture containers are under the same culture conditions, and ensuring the consistency of cell culture results. An electric heating box 9 is fixed to the inner wall of the bottom end of the culture chamber 8, and the electric heating box 9 is electrically connected to the component housing 1 through wires. The electric heating box 9 is located at the bottom end and can... The heat is allowed to diffuse naturally from bottom to top, resulting in a uniform temperature rise inside the incubator 8 and preventing localized overheating. The heating principle is as follows: the component housing 1 supplies power to the electric heating box 9, and the heating element (such as a heating wire) inside the electric heating box 9 converts electrical energy into heat energy, which is transferred to the inside of the incubator 8 through heat conduction and heat convection. This, combined with the controller 4, achieves constant temperature control. The advantages of this design are stable heating, precise temperature control, and the electric heating box 9 is hidden at the bottom, not occupying any incubation space. A maintenance window is also provided inside the front of the component housing 1, and a window protective plate is provided on the outside of the front of the maintenance window. The maintenance window allows staff to inspect the internal components without disassembling the entire component housing 1. The window protective plate protects the internal components from external impacts and dust. It can be opened when maintenance is needed, balancing protection and ease of maintenance.
[0027] like Figure 1 and Figure 4As shown, an anti-static interference device 5 is installed at the top front of the control top box 3. This position is located at the front and top of the control top box 3, allowing the nozzle 13 of the device to accurately cover the front operating area and the box door 2 area, while not obstructing the operator's view and avoiding affecting normal use. The anti-static interference device 5 includes a raising base 14, an ion generator 16, and a blower box 17. The raising base 14 is fixed to the front side of the center of the outer wall at the top of the control top box 3. The function of the raising base 14 is to raise the ion generator 16 and the blower box 17. The height of 7 provides a reasonable height difference for subsequent airflow delivery, ensuring that the ion airflow can smoothly cover the target area. A blower box 17 is fixed to the rear side of the center of the outer wall at the top of the riser base 14. The rear position allows the blower box 17 to be away from the front spray area, avoiding the slight vibration generated during operation from affecting the stability of the spray head 13. An ion generator 16 is fixed to the front side of the center of the outer wall at the top of the riser base 14. The front position facilitates the connection of the ion generator 16 with the front delivery pipe 15 and the gas collection pipe 12, shortening the airflow delivery time. To improve the delivery path and reduce ion loss, the anti-static interference device 5 also includes an air inlet 18. The air inlet 18 is located at the top of the blower housing 17, preventing ground dust from being sucked in. An air outlet is located at the center of the front end of the blower housing 17, connected to the ion generator 16. This connection allows the airflow generated by the blower housing 17 to directly enter the ion generator 16, ensuring that all airflow carries ions for output and preventing leakage. 7 is equipped with a small blower, and the motor of the small blower is a DC brushless motor. The advantages of DC brushless motors are low operating noise, long life and low energy consumption, which are suitable for the low noise environment requirements of the laboratory. The air inlet and outlet of the small blower are connected to the air inlet 18 and the air outlet respectively. Its working principle is that the motor drives the impeller to rotate, forming a negative pressure at the air inlet 18, drawing in external air, which is then pressurized by the impeller and transported from the air outlet to the air outlet, thereby providing power for ion transport and realizing the directional flow of air.
[0028] like Figure 1 and Figure 4As shown, both the ion generator 16 and the small blower are electrically connected to an induction control switch via wires. The induction control switch is electrically connected to the control top box 3 via wires. The linkage control principle is that the control top box 3 can transmit equipment operation status signals (such as the opening and closing signal of the box door 2, and the personnel operation trigger signal) to the induction control switch. When the induction control switch receives a signal (such as a person approaching the operating area, or the box door 2 opening), it will automatically connect the power supply to the ion generator 16 and the small blower to start them. When there is no signal, the power supply will be cut off, realizing automatic start and stop. The advantage of this design is that no manual intervention is required, and the anti-static function can be precisely triggered according to the actual use scenario, which reduces energy consumption and avoids unnecessary airflow interference to the surrounding environment caused by continuous operation. The anti-static interference device 5 also includes a gas collection pipe 12 and a delivery pipe 15. The left and right sides of the front center of the ion generator 16 are longitudinally fixed. A fixed conveying pipe 15 is provided, which can extend vertically forward to shorten the distance with the gas collecting pipe 12 and reduce ion loss during the conveying process. The front ends of the two conveying pipes 15 are connected to the gas collecting pipe 12, and the ion generator 16 is connected to the gas collecting pipe 12 through the conveying pipes 15. The working principle is that the positive and negative ions generated by the ion generator 16 are collected in the gas collecting pipe 12 through the conveying pipes 15. The gas collecting pipe 12 can evenly distribute the ions to each nozzle 13 to ensure that the ion concentration output by each nozzle 13 is consistent, and avoid incomplete static electricity elimination due to insufficient local ions. The gas collecting pipe 12 is located horizontally on the upper front of the control top box 3. The horizontal layout allows the gas collecting pipe 12 to cover the entire operating area at the front of the control top box 3. At the same time, the upper position allows the airflow of the nozzle 13 to be naturally tilted downward or forward without the need to increase the airflow pressure, thus improving the conveying efficiency.
[0029] like Figure 1 and Figure 4As shown, the anti-static interference device 5 also includes multiple nozzles 13. Multiple nozzles 13 are equidistantly arranged at the bottom of the gas collecting pipe 12. This equidistant arrangement ensures that the ion airflow uniformly covers the target area, avoiding blind spots in static elimination. The multiple nozzles 13 consist of an equal number of inclined and vertical nozzles, which are staggered. This staggered arrangement allows the airflow from both directions to complement each other, achieving omnidirectional coverage and avoiding dead zones caused by airflow from a single direction. The inclined nozzles are angled forward at a 45-degree angle at the bottom of the gas collecting pipe 12. This angle design allows the ion airflow to precisely cover the area of the door 2 in front of the control chamber 3. When the test personnel open / close the door 2, the airflow can pre-neutralize the chamber. The static electricity generated by friction between door 2 and cabinet body, and by personnel contact with door 2, has the advantage of covering a range that perfectly matches the opening and closing path of door 2. It avoids the airflow spreading too far due to an excessively large angle, or failing to cover the upper part of door 2 due to an excessively small angle. Multiple vertical air heads are set vertically downward at the bottom of the air collection pipe 12. The vertical downward direction allows the ion airflow to directly act on the controller 4, display screen, and control button area at the front of the control top box 3. The principle is that the vertical downward airflow can accurately target the operation panel and quickly neutralize the static electricity generated in this area due to frequent personnel operation (such as pressing buttons and touching the display screen), avoiding static electricity interference with the signal transmission of controller 4 or damage to electronic components. The advantage of this design is that the airflow direction is direct, the ion utilization rate is high, and static electricity can be eliminated at the source.
