[0023] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0024] Embodiment 1,

[0025] like Figure 1-Figure 5 As shown, a temperature and humidity controllable incubator includes a box body 1, a temperature control device 2, a humidity control device 3, an air circulation device 4, and a main control device 5.

[0026] The main control device 5 is connected to and controls all the electronic components in the incubator, and controls each electronic component to work or stop according to a set program or instruction.

[0027] The box body 1 is composed of a bottom plate 101, a top plate 102, a side plate 103, and a cabinet door 104. The side plate 103 and the cabinet door 104 are arranged above the bottom plate 101, and the top plate 102 is arranged on the top of the side plate 103 and the cabinet door 104. The cabinet door 104 is rectangular in shape, and one side of the cabinet door 104 is fixed between the bottom plate 101 and the top plate 102 through a door shaft. The cabinet door 104 is equipped with a double-layer glass observation window. The cabinet door 104 is provided with a state sensor connected to the control device 5. The state sensor can detect whether the cabinet door 104 is closed.

[0028] The inner space of the box body 1 is a cultivation space. The bottom plate 101 is provided with four supporting feet. The side plate 103 is a hollow structure, and an air circulation device 4 is provided inside. The temperature control device 2 and the humidity control device 3 are provided on the outside of the side plate 103, and the temperature control device 2 and the humidity control device 3 pass through the side plate 103 and enter the inside of the cultivation space. The temperature control device 2 and the humidity control device 3 are arranged behind the side plate 103 on the opposite side of the cabinet door 104, wherein the temperature control device 2 is arranged on the left side and the humidity control device 3 is arranged on the right side.

[0029] A main control device 5 is installed on the top of the box 1. The main control device 5 is a control box, and a circuit is provided inside to connect with the electronic components of the incubator that can control the temperature and humidity. A main controller is installed inside the main control device 5. The main controller can identify signals and control the electronic components to perform corresponding operations according to the signals. The main control device 5 is provided with four operation buttons on one side of the cabinet door, and the operation buttons can adjust the program set inside the main controller.

[0030] The main body of the temperature control device 2 is arranged on the outer side of the side plate of the box body 1 near the left end. The temperature control device 2 includes a temperature sensor 201, a cooling nozzle 202, and a refrigerator 203.

[0031] The temperature sensor 201 is arranged below the top plate 101 near the left end. The temperature sensor 201 is connected to the main control device 5. The temperature sensor 201 detects the temperature in the cultivation space and feeds back the temperature data to the main control device 5. The main control device 5 controls the refrigerator 203 through the circuit. The refrigerator 203 is connected to the refrigeration nozzle 202. The refrigerator 203 receives the control of the main control device 5 and can cool down the cultivation space inside the incubator. The cooling requirement of the cultivation space inside the incubator is met. The refrigerator 203 is a common refrigeration facility, and a refrigeration compressor or a condensing fan can be selected as the refrigeration component of this device to cool down the cultivation space inside the box 1.

[0032] The main body of the humidity control device 3 is arranged on the outside of the side plate of the box body 1 near the right end. The humidity control device 3 includes a humidity sensor 301 , an atomizing nozzle 302 , and a humidifier 303 .

[0033] The humidity sensor 301 is arranged below the top plate 101 near the right end, and is connected to the main control device 5. The humidity sensor 301 detects the humidity in the cultivation space and feeds back the humidity data to the main control device 5. The main control device 5 controls the humidifier 303 through the circuit, and the humidifier 303 is connected to the atomizing nozzle 302.

[0034] When the main control device 5 detects that the humidity signal transmitted by the humidity sensor 301 is lower than the standard, the humidifier 303 is started to humidify the cultivation space. Water mist enters the cultivation space through the atomizing nozzle 302 to increase the humidity.

[0035] The air circulation device 4 is arranged inside the side plate 103 , wherein the air circulation device includes an air outlet 401 , a heating column 402 , an air inlet, a circulation fan and an air duct arranged inside the side plate 103 .

[0036] An air duct is provided inside the side panel 103, and a circulating fan is provided inside the air duct. The opening of the air duct is provided inside the side panel 103 near the left and right sides of the cultivation space. The air is driven by the circulating fan and moves in the cultivation space in the direction of the air outlet-cultivation space-air inlet. A heating column 402 is provided inside the air duct, and the humidifier 303 is also provided with a nozzle entering the air duct. The nozzle connected to the heating column 402 and the humidifier 303 serves as a device for assisting in adjusting the temperature and humidity of the equipment, and assists in quickly adjusting the environment inside the cultivation space when the temperature and humidity of the internal cultivation space change greatly and the reset parameters are greatly different from the existing state.

[0037] A temperature and humidity detection sensor is also provided inside the air duct, and the temperature and humidity detection sensor is connected to the control device 5. The temperature and humidity detection sensor can detect the temperature and humidity of the air inlet and the air outlet of the air duct, and transmit the signal to the control device 5. The control device 5 can change the power of the humidifier 303, the heating column 402, and the compressor 203 by comparing the temperature and humidity in the cultivation space with the temperature and humidity at the inlet and outlet of the air duct, and quickly adjust the environment inside the cultivation space.

[0038] The working principle of this embodiment is:

[0039] Before starting the cultivation, the temperature and humidity control incubator needs to be cleaned to remove contaminants remaining in the cultivation space. The connection between the top plate and the side plate of the cultivation space is set as an arc for easy cleaning. After cleaning, a bracket is set in the cultivation space, and the bracket can be disassembled.

[0040] Before cultivation, it is necessary to set the parameters of the main control device 5, start the temperature control device 2, the humidity control device 3, and the air circulation device 4, and adjust the temperature and humidity of the cultivation space.

[0041] After reaching the set temperature and humidity, place the culture dish on the bracket, and place the materials to be cultured in the culture dish.

[0042] When the incubator is working, it is often necessary to open the cabinet door 104 for inspection, testing, sampling and other operations. At this time, when the main control device 5 detects that the cabinet door 104 is switched from closed to open, the circulating fan is stopped. The operator opens the cabinet door to operate. When the main control device 5 detects that the cabinet door 104 is closed, the circulating fan is turned on again, and the state inside the incubation space is transmitted through various sensors to control the operation of the humidifier 303, the heating column 402, and the compressor 203, and the state inside the incubation space is adjusted to the set parameters.

[0043] When the cabinet door 104 is not closed for a long time, the main control device 5 can be provided with a buzzer or a light bulb to raise an alarm. The main control device 5 can record the data of the temperature and humidity inside the cabinet 1 for a period of time.

[0044] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments.
