[0031] like Figure 1As shown, an infant incubator includes a support device and a box body 13 disposed on the support device. The support device generally includes a support leg 12, and a moving wheel is provided at the bottom of the support leg 12, and the moving wheel can drive the support leg 12 to move. A support column 11 is fixedly installed on the support leg 12, and a box body 13 is fixedly installed on the support column 11. The box body 13 has a cavity inside for placing the infant. One side of the box body 13 is fixedly connected to the support column 11, and an alarm light 14 is provided on the top of the support column 11.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the box 13 is provided with a heating device, a humidifying device, an oxygen supply device and a weighing device. The heating device includes a heating chamber located on one side of the box 13. The heating chamber is a chamber structure surrounded by a heating chamber shell 20 and a return air assembly 19, with a cavity in the middle and openings at the top and bottom. The top opening of the heating chamber is the air inlet of the heating chamber, and the bottom opening of the heating chamber is connected to the air duct 29. The air duct 29 is located between the bed base 17 and the bed tray 16 of the box 13, and the air duct 29 is spread over the upper surface of the bed base 17 as much as possible. The air duct 29 is provided with an air outlet, and the air duct 29 inputs the flowing air in the air duct 29 into the box 13 through the air outlet for the baby to breathe. A heating assembly 25 is provided in the heating chamber, and the heating assembly 25 is used to heat the air. A fan 18 is provided at the bottom of the heating assembly 25. The suction side of the fan 18 is at the top, and the exhaust side is at the side, so that the air heated by the heating assembly 25 can be blown into the air duct 29.

[0033] The humidifying device includes a humidifying tray 28, in which water can be stored. The humidifying tray 28 can heat the water inside to convert the liquid water into water vapor. The opening of the humidifying tray 28, that is, the water vapor outlet thereof, is located in the air duct 29. In this way, the water vapor can be fully and evenly mixed with the heated air in the air duct and input into the box 13 together, so as to ensure that the air breathed by the baby is more uniform and comfortable.

[0034] The oxygen supply device includes an oxygen inlet 32, which is used to supply oxygen into the box 13. The oxygen inlet 32 ​​is arranged at the air inlet of the heating chamber. The oxygen inlet 32 ​​is connected to a second oxygen supply pipe joint 32', which is used to communicate with an external oxygen storage device, which can be an oxygen cylinder, an oxygen bag, etc. The oxygen inlet 32 ​​is arranged near the air inlet of the heating chamber, so that the oxygen entering the box 13 can be heated together with the air.

[0035] Preferably, the oxygen inlet 32 ​​is provided with an oxygen filter 34 and / or a muffler 35. The oxygen filter 34 is used to filter the oxygen input from the outside to ensure the purity of the oxygen; the muffler 35 can reduce the noise introduced by the oxygen pipeline.

[0036] In summary, it can be seen that the present invention optimizes the structure of the heating device, the humidifying device and the oxygen supply device. When the heating device, the humidifying device and the oxygen supply device need to be maintained, it is only necessary to remove the bed tray 16 and the return air assembly 19. Not only does the structure of the incubator have a simple structure and is easy to disassemble and assemble, but also a very obvious beneficial effect is achieved by organically combining the heating device, the humidifying device and the oxygen supply device. The oxygen input into the incubator can be heated together with the air and mixed with the humidified water vapor in the air duct before being sent into the incubator, thereby ensuring that the air in the incubator is warm and the humidity and oxygen concentrations are uniform, making the baby more comfortable.

[0037] To further facilitate disassembly and assembly, the heating chamber housing 20 of the present invention is detachably connected to the return air assembly 19. Preferably, during assembly, only the return air assembly 19 needs to be placed in its installation position, and the two side walls of the return air assembly 19 are in contact with the side walls inside the heating chamber housing 20. When the heating assembly 25 or the fan 18 needs to be inspected or cleaned, only the return air assembly 19 needs to be removed, which is very convenient.

[0038] The heating chamber housing 20 is provided with a temperature sensor 26, a humidity sensor 27, a microphone assembly 33 and an oxygen sensor 31, which are respectively used to detect the air temperature, humidity, oxygen concentration and noise intensity in the box 13. The temperature sensor 26, the humidity sensor 27, the microphone assembly 33 and the oxygen sensor 31 are all connected to the control system of the incubator, and the control system receives these temperature, humidity, oxygen concentration and noise intensity data and compares them with the preset threshold value, and once the range is exceeded, an alarm prompt is issued.

[0039] Preferably, the detection probes of the temperature sensor 26 and the humidity sensor 27 are located near the air inlet of the heating chamber. Since the air at the air inlet of the heating chamber is fully mixed and circulated, it has good uniformity and is more representative.

[0040] Preferably, the oxygen sensor includes a first oxygen sensor 311 and a second oxygen sensor 312 that are adjacently arranged. The two oxygen sensors 31 are adjacently arranged, and when the detection data of the two oxygen sensors 31 differ by a certain threshold, it can be determined that one of the oxygen sensors 31 is abnormal, thereby reducing or even avoiding the risk of infant suffocation that may be caused by the abnormality of the oxygen sensor.

[0041] A main board 21 is also installed at the rear of the heating chamber housing 20. Monitoring electrical components such as the temperature sensor 26, the humidity sensor 27, the microphone assembly 33 and the oxygen sensor 31 are all connected to the main board 21 for communication.

The overflow port 288' is connected to an overflow pipe joint 288, and the overflow pipe joint 288 is led to the outside through a water conduit to prevent excessive water in the humidification tray 28 from overflowing into the air duct 29. The water level sensor includes a high water level sensor 286 and a low water level sensor 285, which are used to detect the high water level and the low water level in the humidification tray 28 to prevent the water level in the humidification tray 28 from being too high or too low. The humidification tray 28 of the present invention has a simple structure and is easy to repair and clean.

[0046] Preferably, the water storage tank 281 includes a tank shell and a heating part 282 arranged on the outer wall of the tank shell, and the heating rod 283 is arranged in the heating part 282, which simplifies the internal structure of the tank shell and ensures that the inner bottom is smooth and easy to clean. The heating part 282 and the tank shell have thermal conductivity. By energizing the heating rod 283 for heating, the heat can be transferred to the water in the water storage tank 281, thereby realizing the vaporization of the water. A thermocouple 284 is also arranged in the heating part 282, and the thermocouple 284 is used to detect the temperature of the heating part 282.

[0047] like Figure 7 , Figure 8 and Fig. 9 As shown, a motor 42 is provided at the bottom of the bed base 17 corresponding to the lower part of the fan 18, and the motor 42 is used to drive the fan 18 to rotate.
