Abstract
Description
Technical Field
[0001] This application relates to the field of microbial culture equipment technology, and more specifically, to a humidification device and an anaerobic workstation. Background Technology
[0002] Humidity is a crucial factor affecting the stability of the microbial culture environment. Therefore, during microbial cultivation, it is necessary to properly set and adjust the humidity parameters within the incubator to ensure normal microbial growth and the smooth progress of experiments. Currently, the main humidification method used in incubators is shallow water tray humidification. This involves placing a shallow water tray inside the incubator and using an electric heating element to heat the water in the tray, causing it to evaporate and release moisture, thereby increasing the humidity of the air inside the incubator. However, this humidification method has a slow humidification rate and is prone to condensation, which can negatively impact the cultivation results. Utility Model Content
[0003] The purpose of this application is to provide a humidification device and an anaerobic workstation, which aims to solve the problems of slow humidification speed and easy condensation in the humidification methods used in incubators in related technologies, thus affecting the culture results.
[0004] In a first aspect, this application provides a humidification device comprising: an external purified water storage device disposed outside the incubator housing for storing purified water; a humidity sensor disposed inside the housing for detecting the humidity inside the housing; and a built-in humidifier disposed on the top plate of the housing; the built-in humidifier being connected to the external purified water storage device via a water supply pipe; the built-in humidifier being equipped with an ultrasonic oscillator and a water filter; the built-in humidifier being used to convert the purified water into atomized particles and spray the atomized particles into the housing when the humidity inside the housing is lower than a target humidity value, through the ultrasonic oscillator and the water filter.
[0005] In the above implementation process, a humidification device is provided, comprising an external purified water storage device, a humidity sensor, and a built-in humidifier. The external purified water storage device is located outside the incubator and is used to store purified water. The humidity sensor is located inside the incubator and is used to detect the humidity inside the incubator. The built-in humidifier is located on the top plate of the incubator and is connected to the external purified water storage device via a water supply pipe. The built-in humidifier contains an ultrasonic oscillator and a water filter. When the humidity inside the incubator is lower than a target humidity value, the ultrasonic oscillator and water filter convert the purified water into atomized particles and spray these particles into the incubator. This microporous ultrasonic humidification technology humidifies the air inside the incubator, resulting in finer atomized particles that are more evenly distributed in the air. It also reduces the likelihood of condensation, eliminates the need for heating, and achieves faster humidification.
[0006] Furthermore, in some embodiments, it further includes: a liquid level sensor disposed inside the water tank of the built-in humidifier, for detecting the liquid level of purified water in the water tank.
[0007] In the above implementation process, a liquid level sensor is installed in the water tank of the built-in humidifier to detect the liquid level of the purified water in the tank, so as to ensure that the humidifier operates within an appropriate water level range, thereby improving the stability of the humidification device.
[0008] Furthermore, in some embodiments, it further includes: a water pump connected between the external water purification storage device and the built-in humidifier, used to extract purified water from the external water purification storage device when the liquid level detected by the liquid level sensor is lower than the target liquid level value, and to transfer the extracted purified water to the built-in humidifier through a water supply pipe.
[0009] In the above implementation process, a water pump is installed between the external water purification storage device and the built-in humidifier. The water pump is activated when the liquid level sensor detects that the liquid level in the built-in humidifier is lower than the target liquid level value, and water is pumped into the built-in humidifier. In this way, there is enough pure water in the built-in humidifier, which effectively prevents the humidifier from burning dry due to lack of water, thereby improving the safety of the equipment.
[0010] Furthermore, in some embodiments, it further includes: an external wastewater collection device, disposed outside the housing, for collecting the water remaining after humidification by the built-in humidifier; and a drainage pump, connected between the external wastewater collection device and the built-in humidifier, for extracting the remaining water in the built-in humidifier through a drainage pipe when the built-in humidifier has completed its humidification operation, and transferring the extracted water to the external wastewater collection device.
[0011] In the above implementation process, an external wastewater collection device and a drainage pump are installed outside the box. The drainage pump is started when the built-in humidifier completes the humidification operation, and pumps out the remaining water in the built-in humidifier and transfers it to the external wastewater collection bottle, so that there is no water accumulation inside the built-in humidifier and the growth of bacteria is reduced.
[0012] Furthermore, in some embodiments, it further includes: a display control system, including a display screen and a quantization controller; the display screen is used to display the detection results of the humidity sensor; the quantization controller is used to control the output of the built-in humidifier based on the detection results of the humidity sensor.
[0013] In the above implementation process, a display control system is added to the humidification device to introduce display and control functions. Quantitative humidification control technology is used to adjust the humidification amount of the built-in humidifier, making the humidity control more precise and the humidity fluctuation inside the device smaller.
[0014] Furthermore, in some embodiments, the mesh size of the water filter is less than 3.5 μm.
[0015] In the above process, medical-grade microporous ultrasonic humidification is used. Through a water filter with a mesh size of less than 3.5μm, the built-in humidifier can effectively filter out tiny impurities and bacteria in the water, ensuring that the water mist released during the humidification process is pure and pollution-free, while making the atomized particles finer.

[0028] As described in the background section, the humidification methods used in incubators in related technologies suffer from slow humidification rates and a tendency to generate condensation, which affects the culture results. Therefore, this application provides a humidification device to solve the aforementioned problems.
[0029] The embodiments of this application will be described below:
[0030] like Figure 1 As shown, Figure 1 This is a schematic diagram of a humidification device provided in an embodiment of this application. The humidification device includes:
[0031] An external water purification storage device 11 is installed outside the incubator 10 and is used to store purified water.
[0032] A humidity sensor 12 is installed inside the box to detect the humidity inside the box;
[0033] A built-in humidifier 13 is installed on the top plate of the housing; the built-in humidifier 13 is connected to the external purified water storage device 11 through a water supply pipe 14; the built-in humidifier 13 is equipped with an ultrasonic oscillator and a water filter; the built-in humidifier 13 is used to convert the purified water into atomized particles through the ultrasonic oscillator and the water filter when the humidity inside the housing is lower than the target humidity value, and spray the atomized particles into the housing.
[0034] The aforementioned humidification device can be applied to various microbial culture and experimental instruments. Taking an anaerobic workstation as an example, an anaerobic workstation is a commonly used piece of equipment in microbial experiments, mainly used for the cultivation and research of microorganisms in an anaerobic environment. The incubator is the core component of the anaerobic workstation; it serves as the anaerobic bacteria culture chamber and also as the operating room for the operator to perform experimental operations. The humidification device provided in this embodiment can humidify the air inside the chamber to maintain the humidity at a suitable level.
[0035] Specifically, the external purified water storage device in the aforementioned humidification system is a water storage device located outside the incubator. The external purified water can be bottled, meaning it can be an external purified water bottle. Alternatively, in other embodiments, the external purified water storage device can be an external purified water tank. This external purified water storage device stores purified water, i.e., sterile water. A humidity sensor is installed inside the incubator to monitor the humidity within the incubator in real time. This humidity sensor can be a lithium chloride humidity sensor, a carbon humidity sensor, an alumina hygrometer, etc. When the humidity sensor detects that the humidity inside the incubator is lower than the target humidity value, it triggers the built-in humidifier to perform humidification. The process of the humidity sensor issuing a control command when detecting a humidity level below the target humidity value has various implementation methods in related technologies; this application embodiment does not improve upon this process.
[0036] A built-in humidifier is installed on the top panel of the enclosure. In practice, the built-in humidifier can be placed in an internal circulation duct, which is connected to the enclosure. During humidification, the built-in humidifier sprays atomized particles into the enclosure through the internal circulation duct. Alternatively, an opening can be provided on the top panel, with the outlet of the built-in humidifier connected to this opening. Sealing strips or sealant are used to enhance the seal at the connection. In this case, during humidification, the built-in humidifier sprays atomized particles into the enclosure through the opening in the top panel. The built-in humidifier contains an ultrasonic vibrator and a water filter. The ultrasonic vibrator uses ultrasonic waves to atomize water into tiny droplets. It includes a transducer and an ultrasonic oscillating plate. The transducer converts electrical energy into mechanical energy, while the ultrasonic oscillating plate converts mechanical energy into ultrasonic energy. The water filter is a device specifically designed to filter impurities in water. It is typically made of corrosion-resistant, high-strength materials such as steel wire, steel plate, polypropylene, polyester, or stainless steel. An ultrasonic oscillator and water filter are incorporated into the built-in humidifier to atomize purified water into finer, more uniform atomized particles. This utilizes microporous ultrasonic atomization humidification technology to humidify the air inside the chamber, resulting in finer atomized particles that are more evenly distributed in the air. It also reduces condensation, eliminates the need for heating, and provides faster humidification. Optionally, the water filter has a mesh size of less than 3.5μm. This means that medical-grade microporous ultrasonic humidification can be used, and the built-in humidifier effectively filters out tiny impurities and bacteria in the water through a water filter with a mesh size of less than 3.5μm, ensuring that the released water mist is pure and uncontaminated, while also producing finer atomized particles.
[0037] The built-in humidifier is connected to an external purified water storage device via a water inlet pipe. The humidifier typically has a built-in water tank to store the water needed for humidification. The purified water stored in the external water storage device is transferred to the built-in humidifier's water tank via the water inlet pipe. In some embodiments, the humidifier further includes a level sensor, located inside the water tank, for detecting the level of purified water in the tank. In other words, by installing a level sensor inside the water tank, the level of purified water in the tank is monitored in real time to ensure that the humidifier operates within an appropriate water level range, thereby improving the stability of the humidifier.
[0038] In some embodiments, the humidification device further includes a water pump connected between the external water purification storage device and the built-in humidifier. This pump draws purified water from the external water purification storage device when the liquid level detected by the level sensor is lower than a target level, and then transfers the drawn purified water to the built-in humidifier via a water supply pipe. The water pump can be a water pump or similar instrument, positioned between the external water purification storage device and the built-in humidifier. When the level sensor detects that the purified water level in the water tank of the built-in humidifier is lower than the target level, it issues a control command, and the water pump starts operating, drawing purified water from the external water purification storage device and transferring it to the built-in humidifier. This ensures that the built-in humidifier has sufficient purified water, effectively preventing the humidifier from running dry due to lack of water, thereby improving the safety of the device. Furthermore, similarly, the process of the level sensor issuing a control command when detecting a liquid level lower than the target level has various implementation methods in related technologies, and this application embodiment does not improve this process.
[0039] In some embodiments, the humidification device further includes: an external wastewater collection device, disposed outside the chamber, for collecting the remaining water after humidification by the built-in humidifier; and a drainage pump, connected between the external wastewater collection device and the built-in humidifier, for extracting the remaining water in the built-in humidifier through a drainage pipe when the built-in humidifier has completed its humidification operation, and transferring the extracted water to the external wastewater collection device. The external wastewater collection device here is also a water storage device disposed outside the incubator chamber, specifically for collecting the remaining water after the built-in humidifier has completed its humidification operation. This external wastewater collection device can be an external wastewater collection bottle. The drainage pump here, like the water pump, is a type of water pump used for pumping water. However, the drainage pump is disposed between the external wastewater collection device and the built-in humidifier. When the built-in humidifier completes its humidification operation, the drainage pump starts operating, extracting the remaining water in the built-in humidifier and transferring it to the external wastewater collection bottle. This ensures that there is no water accumulation inside the built-in humidifier, reducing bacterial growth. The built-in humidifier completes its humidification process by using a humidity sensor to determine if the humidity inside the unit is greater than or equal to a set value.
[0040] Additionally, when the humidification device is equipped with both a water supply pump and a drainage pump, the level sensor can be configured to activate only during the device's self-test phase. Taking an anaerobic workstation as an example, during the self-test phase, because the drainage pump removed the remaining water from the built-in humidifier after the previous humidification cycle, the level sensor detects no water (i.e., the level is below the target level) and issues a corresponding command to trigger the water supply pump to start operating. This pump draws purified water from an external water storage device and transmits it to the built-in humidifier through the water supply pipe. When the level sensor detects that the water is full, water supply stops. This ensures that the humidification water is purified water automatically drawn in only when the device is in use, which helps reduce bacterial growth and improves the air quality inside the chamber.
[0041] In some embodiments, the humidification device further includes a display control system, including a display screen and a quantization controller; the display screen is used to display the detection results of the humidity sensor; the quantization controller is used to control the output of the built-in humidifier based on the detection results of the humidity sensor. In other words, a display control system is added to the humidification device to introduce display and control functions. This display control system can acquire the detection results fed back by the humidity sensor via wired or wireless means, and then display the output through the display screen, allowing the operator to intuitively see the current humidity status inside the incubator. During humidification, the quantization controller adjusts the humidification amount of the built-in humidifier. The quantization controller is an intelligent control device that achieves precise control of the controlled object by quantifying, digitally processing, and controlling the output of the input signal. In this process, the detection results fed back by the humidity sensor are input to the quantization controller. The quantization controller calculates the humidity deviation based on the input signal, thereby calculating the required humidification amount. The larger the humidity deviation, the larger the required humidification amount. After calculation, the quantization controller generates a corresponding control signal and sends it to the built-in humidifier. The control unit of the built-in humidifier adjusts the output of the built-in humidifier according to the control signal. This improves the accuracy of humidity control and reduces humidity fluctuations within the device.
[0042] This application provides a humidification device, which includes an external purified water storage device, a humidity sensor, and a built-in humidifier. The external purified water storage device is located outside the incubator and stores purified water. The humidity sensor is located inside the incubator to detect the humidity inside. The built-in humidifier is located on the top plate of the incubator and is connected to the external purified water storage device via a water supply pipe. The built-in humidifier contains an ultrasonic oscillator and a water filter. When the humidity inside the incubator is lower than a target humidity value, the ultrasonic oscillator and water filter convert the purified water into atomized particles and spray these particles into the incubator. This microporous ultrasonic humidification technology humidifies the air inside the incubator, resulting in finer atomized particles that are more evenly distributed in the air. It also reduces the likelihood of condensation, eliminates the need for heating, and provides faster humidification.

[0049] The working process of this self-cleaning humidifier includes:
[0050] S201.

When the liquid level sensor 19 detects that the water is full, the display control system 20 controls the water pump 15 to stop operating.
[0051] S202. When the humidity sensor 12 detects that the humidity inside the cabinet is lower than the set value, the display control system 20 controls the built-in humidifier 13 to start, and humidification begins.

[0053] S204. When the humidity sensor 12 detects that the humidity inside the cabinet is equal to the set value, the display control system 20 controls the built-in humidifier 13 to turn off, and humidification is completed.
[0054] S205, the display control system 20 controls the drainage pump 17 to start, the drainage pump 17 draws out the remaining water in the built-in humidifier 13 through the drainage pipe 18 and transfers it to the external wastewater collection bottle 16.
