DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See Figure 1 , Figure 1 It is a structural perspective view of an animal incubator capable of regulating the ambient oxygen content, temperature and humidity; the animal incubator capable of regulating the ambient oxygen content, temperature and humidity includes an incubator 13.

[0023] The incubator 13 can be made of one or a combination of stainless steel, organic glass, polycarbonate, or quartz glass as needed. An openable incubator door 17 is provided on the front side of the incubator 13, and a silicone sealing gasket is installed on the inner side of the incubator door 17 for sealing.

[0024] The incubator 13 has a water tray 14 at the bottom, connected to an external water inlet pipe with an inlet valve installed. A sterilizing UV lamp 20 is mounted on the top of the incubator 13, and a heating plate 16 is installed at the rear of the incubator 13. A circulating fan 19 is installed on the same side of the incubator 13 as the heating plate 16. A support rack 15 is located at the rear of the incubator 13, which can accommodate several independent culture chambers 18. The support rack 15 is higher than the water tray 14. Humidity inside the incubator is controlled by a humidifier 11 and a manually adjustable water inlet valve connected to the water tray 14.

[0025] The rear bottom of the incubator 13 is connected to an air source 1, a nitrogen source 2, and an oxygen source 3 via an air inlet pipe 12. Specifically, the air inlet pipe 12 is connected to the air, nitrogen, and oxygen pipes via a four-way pipe joint 10. A first gas filter 4, a second gas filter 5, and a third gas filter 6 are installed on the air, nitrogen, and oxygen pipes, respectively. The air pipe is connected to the air source 1, the nitrogen pipe is connected to the nitrogen source 2, and the oxygen pipe is connected to the oxygen source 3. A first solenoid valve 7, a second solenoid valve 8, and a third solenoid valve 9 are installed on the air, nitrogen, and oxygen pipes, respectively.

[0026] In addition, a gas humidifier 11 is installed on the air inlet pipe 12 to adjust the humidity in the incubator.

[0027] A control display 22 is installed on the top of the incubator 13. The control display 22 is electrically connected to the oxygen sensor 23, the carbon dioxide sensor 24, the temperature and humidity sensor 25, and the pressure sensor 26 through the fourth signal transmission line 30, the fifth signal transmission line 31, the sixth signal transmission line 32, and the seventh signal transmission line 33 respectively. The oxygen sensor 23, the carbon dioxide sensor 24, the temperature and humidity sensor 25, and the pressure sensor 26 are all inserted into the top of the incubator 13. An exhaust pipe 21 is also installed on the top of the incubator 13. A one-way valve and a solenoid valve are installed on the exhaust pipe 21, which can be used to regulate the pressure in the box.

[0028] The incubator 13 is connected to an inlet pipe 12 and an exhaust pipe 21. The inlet pipe 12 has solenoid valves for the corresponding gases, controlling the type and volume of air flow. The solenoid valve in the exhaust pipe 21 is electrically connected to a control display 22, and exhaust is controlled in real time by a one-way valve in conjunction with the solenoid valve. The solenoid valves in both the inlet and exhaust pipes 12 and 21 also control the pressure within the chamber. By controlling the fluctuations and differences between the oxygen and carbon dioxide levels and the set and measured pressure values ​​displayed on the control display 22, the solenoid valves regulate the flow rates of the different gases in real time to achieve the set oxygen and carbon dioxide levels and chamber pressure. (Since the CO2 content in the normal living environment of organisms is very low, a separate CO2 gas source is not introduced.)

[0029] In addition, the control display 22 is electrically connected to the first solenoid valve 7, the second solenoid valve 8, and the third solenoid valve 9 via a first signal transmission line 27, a second signal transmission line 28, and a third signal transmission line 29, respectively. The control display 22 is also electrically connected to the gas humidifier 11, the heating plate 16, and the circulation fan 19. The control display 22 is electrically connected to the temperature and humidity sensor 25, and is also electrically connected to the heating plate 16 and the circulation fan 19 to control the temperature inside the chamber in real time.

[0030] The utility model discloses an animal incubator capable of regulating ambient oxygen content, temperature, and humidity. The incubator comprises multiple gas sources, an air intake pipe, a gas filter, a solenoid valve, a gas humidifier, an incubator body, sensors, a signal transmission line, a control display, a heating plate, a circulating fan, and a sterilizing ultraviolet lamp. Based on the ambient oxygen and carbon dioxide content required for the experiment, the mixed air, nitrogen, and oxygen gas sources are connected to the corresponding gas filters and solenoid valves. The multiple gases are mixed through a four-way air pipe joint, flow through the gas humidifier, and then enter the incubator through the air intake pipe. The incubator is equipped with a heating plate, a circulating fan, a water tray, and other components, combined with a temperature and humidity sensor and a control display to regulate the ambient temperature and humidity. An oxygen sensor, a carbon dioxide sensor, and a pressure sensor are used to monitor the oxygen and carbon dioxide content and pressure within the incubator. Based on fluctuations and differences between the set and detected values ​​of each gas and the incubator pressure, the solenoid valves are used to regulate the intake and exhaust flow rates of each gas in real time, thereby achieving real-time and accurate regulation of the ambient oxygen and carbon dioxide content and pressure.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
