Specifically, a pressure-regulating fan device based on an indoor air supply system, please refer to fig. 1-2, which is adapted to an air supply pipeline of the indoor air supply system buried in a wall; the air conditioner comprises a face shell 1 and a bottom shell 2, wherein a containing cavity formed by enclosing the face shell 1 and the bottom shell 2 is internally provided with a fan unit 3 and an electric control unit 4 which are electrically connected; the bottom shell 2 is provided with a ventilation grid 21 communicated with an air supply pipeline; the face shell 1 is provided with an air outlet grid 11, and the fan unit 3 is arranged between the ventilation grid 21 and the air outlet grid 11 to form a supercharging air duct; the electric control unit 4 senses the temperature in the air supply pipeline to control the on and off of the fan unit; for example, in a refrigeration mode, when the temperature in the pipeline is reduced to a preset refrigeration temperature threshold value, the indoor air supply system is in the refrigeration mode, so that the fan is turned on to increase the air volume, and cold air is enabled to rapidly fill the whole indoor space; when the temperature in the air supply pipeline slowly rises to be higher than the refrigerating temperature threshold value, the user turns off the refrigerating mode of the air supply system, so that the fan can be turned off; for another example, in a heating mode, if the temperature in the air supply pipeline gradually rises to be greater than a heating temperature threshold preset by the electronic control unit, the fan is correspondingly turned on to further convey the hot air in the air supply pipeline to the indoor space, and similarly, when the temperature in the air supply pipeline gradually falls below the heating temperature threshold, the fan unit is turned off; of course, in both modes above, the wind speed of the fan can be adjusted. Therefore, the cold air or the hot air in the ventilation pipeline is pumped into a room by the fan unit through the matching with the ventilation pipeline, and the effects of pressurization diffusion and uniform conveying are achieved.
