[0014] A method for adjusting a fresh air thermal management adjustment device of a heat pump air conditioner, the specific steps are as follows:

[0015] Step 1: According to the demand, start the electric heating wire for heating or start the compressor to use the heat absorption pipe to absorb heat from the air for cooling, and start the fan 3 simultaneously to use the air supply pipe, the middle cavity and the adjustment component to supply air to the inside of the air conditioning cabinet to achieve continuous gas delivery;

[0016] Step 2: Humidity adjustment, by starting the motor to drive gear 1 to mesh with gear 2 to drive the threaded rod to rotate, and by using the rotation of the threaded rod to drive the movable limit plate to pull the telescopic tube 3 downward, and each time the telescopic tube 2 is moved a certain distance, the air outlet hole on the inner telescopic tube 2 is offset and overlapped with the air outlet hole on the telescopic tube 1, so as to reduce the air vent of the entire adjustment component in the telescopic tube 1 section, and at the same time, the hole on the telescopic tube 2 that is smaller than the air outlet hole and is located at the bottom of the air outlet hole is exposed and placed in water, and a part of the gas is placed in the water by air pressure and then floated out to achieve the purpose of increasing the humidity, which can well control the humidity and adjust the humidity, and achieve the humidity adjustment effect with a simple mechanical structure, which is not easy to be damaged, has a long service life, and is easy to operate;

[0017] Step 3: When the water level inside the air-conditioning cabinet is insufficient, use the air outlet holes on the telescopic tube 1 for ventilation. When the water level is at the standard height, the air outlet pressure of the air outlet holes on the telescopic tubes 2 and 3 is relatively large. Therefore, the large air outlet pressure of the air outlet holes on the telescopic tube 1 will push the rotating plate to rotate. When the water level at the bottom is low and the air outlet pressure resistance of the air outlet holes on the telescopic tubes 2 and 3 is relatively small, the air outlet pressure of the air outlet holes on the telescopic tube 1 will decrease accordingly. The rotating plate rotates a part due to the rebound force of the torsion spring. At this time, the trigger plate is driven to trigger the touch switch to automatically replenish water using the water pump. Conversely, the water can also be automatically cut off. As the water level rises, the resistance is restored, and the air pressure of the air outlet holes on one side of the rotating plate is restored, thereby continuing to push the trigger plate to disconnect the touch switch.

[0018] The technical effects and advantages of the present invention are as follows: 1. The starting motor drives the gear 1 to mesh with the gear 2 to drive the threaded rod to rotate, and the rotation of the threaded rod drives the movable limit plate to pull the telescopic tube 3 downward. After each movement of a certain distance, the air outlet hole on the telescopic tube 2 located inside overlaps with the air outlet hole on the telescopic tube 1, thereby reducing the air vent of the entire adjustment component in the telescopic tube 1 section. At the same time, the hole on the telescopic tube 2 that is smaller than the air outlet hole and located at the bottom of the air outlet hole is exposed and placed in water, and a part of the gas is placed in the water and then floated out by air pressure to achieve the purpose of increasing the humidity. The humidity can be well controlled and adjusted as a whole. The simple mechanical structure achieves the humidity adjustment effect, is not easy to be damaged, has a long service life, is easy to operate, and can reduce the dryness of the air through convenient humidity adjustment, greatly reducing the occurrence of respiratory symptoms.

[0019] 2. Use the air outlet on the telescopic tube 1 for ventilation. When the water level is at the standard height, the air outlet pressure of the air outlet on the telescopic tube 2 and the telescopic tube 3 is relatively large. Therefore, the large air outlet pressure of the air outlet on the telescopic tube 1 will push the rotating plate to rotate. When the water level at the bottom is low and the air outlet pressure resistance of the air outlet on the telescopic tube 2 and the telescopic tube 3 is relatively small, the air outlet pressure of the air outlet on the telescopic tube 1 will decrease accordingly. The rotating plate rotates a part due to the rebound force of the torsion spring. At this time, the trigger plate is driven to trigger the touch switch to automatically replenish water using the water pump. Conversely, the water can also be automatically cut off. As the water level rises, the resistance is restored, and the air pressure of the air outlet on one side of the rotating plate is restored, thereby continuing to push the trigger plate to disconnect the touch switch.
