Description

Technical Field

[0001] The utility model relates to a controller, in particular to a CO2 incubator controller. Background Art

[0002] The existing CO2 incubator has the following disadvantages:

[0003] Higher cost: CO2 incubators require complex control systems to maintain stable CO2 concentration, temperature and humidity.

[0004] High energy consumption: CO2 incubators consume more energy when maintaining a constant CO2 concentration and temperature, especially when the door is opened frequently, which leads to energy waste.

[0005] Difficult to clean and disinfect: Although some CO2 incubators use easy-to-clean materials, such as a 100% pure copper interior surface, CO2 incubators can be more difficult to clean and disinfect overall, requiring special handling and maintenance procedures.

[0006] High potential risk of contamination: If the CO2 incubator is not cleaned and maintained properly, it may increase the risk of contamination during cell culture.

[0007] Differences in heating systems: The heating systems of CO2 incubators are divided into water-jacketed and air-jacketed types, each with its own advantages and disadvantages. For example, water-jacketed heating is more stable, but the heating speed is slower; air-jacketed heating is faster, but the stability is slightly inferior. Utility Model Content

[0008] The technical problem to be solved by the utility model is: to provide a CO2 incubator controller in order to overcome the deficiencies in the prior art.

[0009] The utility model solves the technical problem by adopting the following technical solution: a CO2 incubator controller, comprising an instrument control panel, on which a CO2 sensor, a CO2 valve, a CO2 air pump, a temperature sensor, a heater and a control panel are electrically connected;

[0010] The CO2 sensor monitors the CO2 concentration in the incubator. When the concentration is lower than the preset value, the instrument control board controls the CO2 valve to open. When the concentration is higher than the preset value, the instrument control board controls the CO2 exhaust pump to start.

[0011] The temperature sensor monitors the temperature in the incubator. When the temperature is lower than the preset value, the instrument control panel controls the heater to heat up.

[0012] The instrument control panel displays various data through the control screen and issues instructions to the instrument control panel through the control screen.

[0013] Furthermore, the CO2 sensor has an accuracy of 0.1% and a fluctuation of 0.2%; a CO2 measurement range of 0.0% to 20.0%; and a CO2 control range of 0.0% to 20.0%.

[0014] Furthermore, the number of the temperature sensors and the number of the heaters are both multiple,

[0015] The temperature sensors include ambient temperature sensor, door temperature sensor, over-temperature sensor and box temperature sensor;

[0016] The heater includes a box heater, a door heater and a sub-heater;

[0017] The box heater starts according to the feedback data of the box temperature sensor, the door heater starts according to the feedback data of the door temperature sensor, and the auxiliary heater assists in heating;

[0018] Temperature sensor temperature measurement accuracy: 0.1℃, fluctuation 0.3℃;

[0019] Temperature sensor measuring range: 0.0℃~100℃;

[0020] Temperature control range: RT+3.0℃~50.0℃.

[0021] Furthermore, the heater delivers heated gas into the incubator via a fan, and the fan is electrically connected to the instrument control panel.

[0022] Furthermore, the instrument control panel is also electrically connected to one or more of a sterilization lamp, an expansion interface, a humidity sensor and a pressure plate.

[0023] The beneficial effects of the utility model are as follows: the CO2 incubator controller of the utility model first monitors the concentration of CO2 in the incubator in real time through the CO2 sensor, opens the CO2 suction pump to discharge when the concentration is high, and opens the CO2 valve to supplement CO2 when the concentration is low, so as to ensure that the concentration of CO2 in the incubator is maintained at the set value;

[0024] Secondly, the heating method is changed, and the heating is divided into two parts: heating inside the box and heating the door. This is to deal with the problem of frequent opening of the door causing a sudden drop in the temperature inside the box and slow heating after closing the door. The heated gas is sent into the incubator through a fan, which is more efficient, more uniform and more stable than the existing one.

[0025] Finally, by adding a pressure plate to sense whether the door is closed properly, energy consumption can be reduced; using a sterilization lamp for disinfection, if permitted, the incubator can be sterilized while in use to solve the problems of high difficulty in cleaning and disinfecting the incubator and high potential contamination risk during the use of the incubator.

[0026] In summary, the utility model has the characteristics of simple maintenance, simple operation, low energy consumption, high reliability and stable heating. BRIEF DESCRIPTION OF THE DRAWINGS
