[0016] The specific implementation of an ultrasonic humidification system for an incubator of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] See attached Figures 1 to 5 The front of the biological incubator 1 is a front door 2, and the left, right, and rear side walls are provided with a thermal insulation sealing layer 3. An installation cavity 5 is formed in the rear wall 4, and an auxiliary water tank 6 is installed in the installation cavity 5. A water inlet 7 is provided on the outer side of the auxiliary water tank 6, and a float water supply valve 8 in the auxiliary water tank 6 is connected to the water inlet 7 on the inner side of the auxiliary water tank 6. A drain outlet 9 is provided below the auxiliary water tank 6. The drain outlet 9 is used to connect to the water outlet valve for drainage and to regularly empty the auxiliary water tank 6 for cleaning and maintenance. The figure only shows the position of the drain outlet 9, and does not show the water outlet valve and pipeline connection. This can be achieved using a conventional drainage pipeline.

[0018] A main water tank 10 is hung on the rear wall 4 of the incubator 1. The water outlet of the main water tank 10 is connected to the water inlet 7 on the outside of the auxiliary water tank 6 through a pipeline. The float water supply valve 8 controls the water supply of the main water tank 10 in the auxiliary water tank 6 to keep the water level of the auxiliary water tank 6 at a stable value.

[0019] A humidifying chamber 11 is arranged in the auxiliary water tank 6. The humidifying chamber 11 is located near the inner side of the incubator 1. The bottom of the humidifying chamber 11 is connected to the auxiliary water tank 6. An ultrasonic atomizing plate 12 is installed at the bottom of the auxiliary water tank 6. The mist outlet front of the ultrasonic atomizing plate 12 is arranged on the lower opening of the humidifying chamber 11. The water level in the auxiliary water tank 6 is relatively low. The ultrasonic atomizing plate 12 is controlled by the electronic control unit 13. When the ultrasonic atomizing plate 12 is controlled to work, mist is sprayed from the bottom of the humidifying chamber 11.

[0020] An air outlet 14 is provided above the humidifying chamber 11 and extends into the incubator 1 ; an air inlet 15 is provided below the humidifying chamber 11 and extends into the incubator 1 and can be bent downward. The float water replenishing valve 8 of the auxiliary water tank 6 controls the water level of the humidifying chamber 11 so that the water level is lower than the position of the air inlet 15 .

[0021] A top cover 16 is provided on the top of the auxiliary water tank 6, and an air outlet 14 is located on this cover. The air outlet 14 bends and extends horizontally into the incubator 1. The air outlet 14 extends directly into the incubator 1 from the inner side of the auxiliary water tank 6 and can be bent upward. A guide cavity 17 is provided within the incubator 1, located at the position of the auxiliary water tank 6. The height of the guide cavity 17 is close to the internal height of the incubator 1. The air inlet 15 and the air outlet 14 both extend into the guide cavity 17.

[0022] In addition, a low water level alarm 18 is installed in the auxiliary water tank 6. The upper end of the low water level alarm 18 is fixed to the top cover 16 and is connected to the electronic control unit 13. The electronic control unit 13 is located at the top of the incubator 1. The ultrasonic atomization plate 12 and the low water level alarm 18 are both electrically connected to the electronic control unit 13 and controlled by the electronic control unit 13. The electrical connection can be connected to the electronic control unit 13 via a wire through the interlayer of the side wall of the incubator 1.

[0023] In order to achieve real-time stabilization of the humidity in the incubator 1, a humidity sensor (not shown in the figure) is set in the incubator 1. The humidity sensor is connected to the electronic control unit 13. The electronic control unit 13 adjusts the atomization amount of the ultrasonic atomization plate 12 according to the feedback of the humidity sensor.

[0024] When the present invention performs humidification, the electronic control unit 13 starts the ultrasonic atomizing plate 12, and the ultrasonic atomizing plate 12 forms a coordinated spray in the humidification chamber 11. Since the spray has a certain flow rate, it is ejected from the air outlet 14 along the upper end of the guide chamber 17 (in the direction of the arrow in the figure), and the spray enters the interior of the incubator 1 and diffuses. Since a certain negative pressure is formed in the air inlet 15 and is transmitted to the lower port of the guide chamber 17, the spray at the bottom of the incubator 1 enters the air inlet 15 from the lower port of the guide chamber 17, forming a mist circulation with the humidification chamber 11, so that the entire incubator 1 is filled with mist and maintains a predetermined humidity. The electronic control unit 13 can adjust the vibration frequency of the ultrasonic atomizing plate 12 according to the humidifier in the incubator 1, thereby adjusting the amount of mist and the speed of mist, thereby changing the humidity parameters in the incubator 1.

[0025] As atomization progresses, the water level in the auxiliary water tank 6 drops. When it drops to a certain level, the float water supply valve 8 opens, and the main water tank 10 replenishes water to the auxiliary water tank 6. After the water level reaches a predetermined value, the float water supply valve 8 closes. If the main water tank 10 is short of water, the float water supply valve 8 opens, but water supply fails. At this time, when the water level drops further, the low water level alarm 18 of the auxiliary water tank 6 sounds, prompting the staff to add water to the main water tank 10.

[0026] The above are only preferred embodiments of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
