That is to say, when the air purifier is powered on, the gauge pressure sensor assembly 100 outputs different pressure detection data according to the water level in the humidifying pan 300, and sends the different pressure detection data to the electric control board 200, and the electric control board 200 The change of the water level in the humidifying pan 300 is judged according to different pressure detection data.

Specifically, water has a certain pressure, and the pressure produced by water at different heights is also different. Therefore, the gauge pressure sensor assembly 100 is arranged under the humidification pan, and when the water level in the humidification pan changes, the pressure of the water sensed by the gauge pressure sensor assembly 100 will change with the change of the water level in the humidification pan. Furthermore, the gauge pressure sensor assembly 100 can convert the sensed water pressure into pressure detection data according to preset rules and send it to the electric control board 200 , wherein the pressure detection data indicates the height of water in the humidification pan 300 .

For example, if the current water level in the humidification pan is h1, the gauge pressure sensor assembly 100 outputs a pressure detection value A corresponding to the water level height h1 in the humidification pan, and then the gauge pressure sensor assembly 100 sends the output pressure detection value A to The electric control board 200, the electric control board 200 can obtain the water level information in the humidification pan according to the pressure detection value A.

As another example, if the current water level in the humidifying pan is h2, the gauge pressure sensor assembly 100 outputs a pressure detection value B corresponding to the water level h2 in the humidifying pan. Then the gauge pressure sensor assembly 100 sends the output pressure detection value B to the electric control board 200, and the electric control board 200 can obtain the water level information in the humidification pan according to the pressure detection value B.

It should be understood that different gauge pressure sensor assemblies 100 have different relationships between pressure detection data and water level, so the conversion relationship between pressure detection data and water level can be determined according to the specific gauge pressure sensor assembly 100 . Specifically, in one embodiment of the present invention, the conversion relationship between the pressure detection data and the water level can be pre-stored in the electric control board 200, after the electric control board 200 receives the pressure detection data output by the gauge pressure sensor assembly 100, it can The water level information in the humidification pan is determined through the pre-stored conversion relationship.

As a result, the water level of the humidifying pan of the air purifier can be accurately detected, which facilitates flexible design of the auxiliary structure of the humidifying pan and satisfies the needs of product diversification.

According to an embodiment of the present invention, the gauge pressure sensor assembly 100 is fixed under the humidification plate 300 , and the gauge pressure sensor assembly 100 is pluggably connected to the electric control board 200 . Since the humidification plate 300 is detachable, and the gauge pressure sensor assembly 100 is fixed under the humidification plate 300, the gauge pressure sensor assembly 100 is pluggably connected to the electric control board 200. For example, the pluggable connection can The connection mode of the male interface and the female interface is adopted.
