The light absorbing and water absorbing material 120 is used for absorbing water in the axis of the water tank 110, and is disposed on the top of the inner wall of the water tank 110, directly above the light absorbing and water absorbing material 120, and facing the light absorbing and water absorbing material 120. The humidity sensor 180 is installed indoors or the humidity sensor 180 provided in the air conditioner is used to detect the humidity of the indoor air, and the humidity sensor 180 transmits an indoor humidity signal to the controller 200. The controller 200 controls the illumination module 130 to be turned on or off based on the air pressure in the water tank 110 and the humidity of the indoor air, light emitted when the illumination module 130 is turned on is irradiated on the light absorption and water absorption material 120, and the light absorption and water absorption material 120 generates heat after absorbing the light, so that the absorbed water is gradually evaporated to form water vapor. Meanwhile, when the humidity sensor 180 detects that the humidity of the indoor air is too low, the controller 200 controls the air outlet valve 160 to be opened, and the wet air in the water tank 110 enters the indoor space through the air outlet 111 to humidify the indoor air. The illumination module 130 and the air outlet valve 160 are kept open until the humidity of the indoor air rises to the preset value range. Therefore, the indoor humidification is automatically realized, and the indoor air humidity is stably kept in a comfortable range. The humidifying device can also be used independently of the air conditioner, the air conditioner runs normally, the humidifying device controls the indoor air humidity independently, and the humidifying device can be suitable for being matched with various air conditioners to be used and is high in universality.

The water tank 110 is a light-tight high-strength casing, so that water in the water tank 110 is prevented from being consumed by steam generated by irradiating the light absorption and water absorption material 120 with natural light in a closed state of the light module 130, and the light module 130, the light absorption and water absorption material 120, the pressure sensor 140 and the water level sensor 150 in the water tank 110 are protected.

With the above possible implementation manner of the first embodiment of the present application, as the water in the water tank 110 gradually evaporates, the liquid level in the water tank 110 gradually decreases, and the liquid level gradually increases when water is added.

After the partition 113 is disposed, for example, a partition is fixed at the bottom of the inner side of the water tank 110, the top of the partition is exposed out of the water surface, a through hole 1131 is formed in the middle of the partition for water to flow through, the partition divides the bottom space of the water tank 110 into a first water storage cavity 117 and a second water storage cavity 118, the liquid surface of the first water storage cavity 117 forms a floating region, the second water storage cavity 118 forms a non-floating region, the light absorbing and water absorbing material 120 can only float in the floating region due to the blocking of the partition, and the influence on the stability of the light absorbing and water absorbing material 120 is reduced in the processes of water intake, air intake or air exhaust.

When the chamber is humidified, the controller 200 controls the second valve 162 to be closed and the first valve 161 to be opened, and the water vapor is supplied into the chamber through the first outlet pipe 114.
