The invention discloses a ceiling-suspended type humidifying, heating and disinfecting device. The ceiling-suspended type humidifying, heating and disinfecting device comprises a base, a supporting frame plate and a horizontal supporting plate, a central processing unit is installed on the base, fixing plates are arranged on the central processing unit, extending pipes are fixed to the front sideof the supporting frame plate, the supporting frame plate is located in the middles of supporting rods, moving grooves are formed in the horizontal supporting plate, and the horizontal supporting plate is located under fans. According to the medical visual ward humidifying, heating and disinfecting system, the location height of the supporting frame plate on the supporting rods can be adjusted through cooperation between the supporting rods and the supporting frame plate, the overall length of outer protecting sleeves and detecting rods is changed, the outer protecting sleeves have a protecting effect on temperature sensors and humidity sensors which are arranged on the detecting rods, the rotation speed of the fans also can be automatically adjusted, and the intelligent degree of the system is improved.
