Abstract

[0002] In the field of biological products and vaccine research and development, cell culture is often required for development. In the process of cell culture, many parameters need to be paid special attention to, such as the rotation speed, pH, temperature, culture humidity, etc. of cell culture; if the parameters are inaccurate or cannot be controlled, there will be problems such as poor cell state, unclear boundaries, low viability, and low density. When the humidity cannot be controlled, there will be problems such as large evaporation of cell culture medium and increased osmotic pressure, resulting in reduced cell viability or even death. Especially when cells are cultured in well plates, if the humidity is not controlled, 1mL of culture medium in the well plate can completely evaporate within 3 days, resulting in cell death.
[0003] As the main body for controlling these parameters, the cost of the shaking table is relatively high. Whether the function of controlling humidity can be achieved will widen the cost gap. Due to the small size of the shaking table, it is impossible to increase the humidity inside the shaking table, so an external device needs to be added; if an external device is added, the entire size of the shaking table will become larger. Therefore, it is urgent to propose an accurate, simple and low-cost device to solve the existing shaking table humidity control problem. Utility Model Content
[0004] In view of this, the purpose of the utility model is to provide a device for automatically controlling the humidity of a shaking table to solve the problems existing in the above-mentioned prior art.

[0041] The infrared water level alarm 10 is arranged at the bottom of the water tank 9 and is not adjacent to the bottom plate of the water tank 9 .
[0042] A water level limiter 3 is also provided in the side wall water tank 2, and the water level limiter 3 is electrically connected to the control mechanism 5;
[0043] The water level limiter 3 is arranged at the bottom of the side wall water tank 2 and is not adjacent to the bottom plate of the side wall water tank 2 .
[0044] The pipeline is provided with a water pump, and the water pump is electrically connected to the water level limiter 3 .
[0045] The steam generating module 7 is a humidifier.
[0046] The display module 6 is a digital display screen.
[0047] It should be noted that the steam generation module is placed in the side wall water tank, and the side wall water tank is equipped with a water level limiter to ensure the water level in the tank, thereby ensuring that the steam generator can continue to work. The water tank is connected to the external water to ensure the water source, and the external water tank has an infrared water level alarm to effectively prevent the water level from being too low.
[0048] The present application also provides the following embodiments:
[0049] Embodiment 1:
[0050] The device for automatically controlling the humidity of the shaking table provided in this embodiment mainly includes 7 modules. The first module is an external water tank 9, which is a 5L-10L plastic bucket or plastic with a cover, placed at any position outside the shaking table. The function of the water tank 9 is to provide a water source; at the same time, the water tank also has an infrared water level alarm 10 to prevent the water level from being too low; the infrared water level alarm is constructed by a third party with complete certificates, and the model is: Xingkechuang XKC-Y29A-NPN; the second module is a connecting pipeline, that is, a passage connecting the outer water tank and the inner water tank of the shaking table, which can be a PVC pipeline with an inner diameter of 22 1-2m. Since the price of PVC pipes is cheap, maintenance only requires replacing the pipeline; the third module is a wall-attached water tank 2 of the shaking table 1, which has high viscosity and can be attached to the inner wall of the shaking table 1; The length of the wall-attached water tank 2 is slightly smaller than the inner length of the shaking table 1, and the width is 5-10cm, which does not affect the use space of the shaking table 1. The height can be set to 10cm to ensure that sufficient water is placed in the wall-attached water tank 2; the fourth module is a water level limiter 3, which is used to ensure the water level of the wall-attached water tank 2 in the shaking table 1; the fifth module is a steam generation module 7, which can float on the water surface and has a filter element in the center to produce dense steam to achieve the effect of humidification; the steam generation module 7 is connected to the control mechanism 5, and the control mechanism 5 controls whether it works; the sixth module is the control mechanism 5, which includes 3 parts: an analog-to-digital conversion module, whose main function is to collect data transmitted by the humidity sensor, and convert the humidity change data into an electrical signal, and send it to the relay module. When the humidity in the box is lower than the preset value, the relay module contacts in the controller are closed, the humidifier is powered on and starts to work, and the box is humidified; after a period of time, the humidity in the box is ≥ the set value, the relay contacts in the controller are disconnected, and the humidification stops. The display module converts the electrical signal output by the humidity sensor into a digital signal, and displays the humidity in the shaking table on the screen using a digital display method; the humidity sensor is mainly used to measure the humidity in the shaking table and transmit the value to the control mechanism. The humidity sensor was purchased from a third party, model: Weier Innovation Electronics (National Standard) W2023220V 10A, and its quality certificate and after-sales service are guaranteed.
[0051] The water in the water tank is ultrapure water. During the steam generation process, only water vapor is produced, which does not cause harm to the environment. Moreover, it is cold steam and does not cause dangers such as burns. At the same time, the power supply of all equipment is very small and is in the same location as the shaker power supply, so there is no need to worry about power outages.
[0052] The specific working process of the device for automatically controlling the humidity of the shaking table provided in this embodiment is as follows: the outer water tank 9 has an infrared water level alarm 10 to control the water level. The water level limiter 3 inside the shaking table 1 is connected to the outer water tank 9 through a PVC pipe with an inner diameter of 22 to form a feedback device. When the water level inside the shaking table 1 is low, the water in the outer water tank 9 automatically enters the wall-attached water tank 2 through the PVC pipe until the water level reaches the corresponding position, thereby realizing the automatic control of the water level inside the shaking table 1. This device ensures the water level inside the shaking table 1. The control mechanism 5 connects the steam generator 7 and the humidity sensor 4. When the control mechanism 5 detects that the humidity is less than the set value, the steam generation module 7 is controlled to start working until the humidity is detected to be greater than the set value, and the steam generation module 7 stops working, thereby realizing the automatic control of the humidity of the shaking table 1.
[0053] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
