It also includes a detection unit; the detection unit is installed on one side of the inner wall of the base frame 1; the detection unit is electrically connected to the control system; the detection unit includes an ultrasonic sensor, a humidity sensor and a position sensor; Humidity is detected and controlled, so a humidity sensor is needed; and the humidification device needs to automatically change the working position, and the position needs to be positioned, so a position sensor is needed; and during the movement, obstacles on the way need to be avoided, so it is necessary ultrasonic sensor.

Specific embodiment two:

Referring to Figure 10, it is used in small spaces such as bedrooms, elderly rooms, and baby rooms, as well as indoors that require quietness and safety; the mist generating device at this time needs to have the characteristics of low noise, low power, and no hidden dangers;

At this moment, the mist generating device selects the evaporative unit, thereby adopting the evaporating box 33; the inside of the evaporating box 33 is equipped with an evaporating plate 331; the evaporating plate 331 is a cylindrical structure, and the side wall of the evaporating plate 331 is fixedly equipped with a sponge; The inhaled air will form an airflow, and this airflow will pass through the evaporating plate 331; it can be known from physical knowledge that under the condition of air flow, the evaporation speed of water will become faster, so this airflow will drive the water attached to the inside of the sponge to evaporate, The evaporated water vapor mixes with the inhaled air and enters the interior of the ion reaction device; after a certain period of use, open the water tank 4 and replace the internal sponge to complete the maintenance and cleaning; since no mechanical structure is used to complete the evaporation, it is quiet , safety and other features, suitable for sensitive groups and bedrooms and other scenes.

working principle:

During the day, the control system starts the driving device and controls the humidifying device to move to the ventilation opening, such as the window, the door, etc.; at this time, the humidifying device purifies the indoor air with the help of the internal and external circulation of air and the ion reaction device, and passes the mist through the mist The conveying device is input to the tuyere; the purified air and water vapor are conveyed to the room by means of air circulation; at night, the control system starts the driving device and controls the humidifying device to move to the bedside, sofa, etc. At this time, priority is given to purification and humidification near the user air.

Since the humidity is not as high as possible, it is necessary to detect and control the humidity in the room, so a humidity sensor is needed; and because the humidifying device needs to automatically change the working position, the position needs to be positioned, so a position sensor is needed; and During the process, obstacles on the way need to be avoided, so ultrasonic sensors are needed.

When the humidifier is not in use, due to the certain volume of space, the storage device will have space constraints, and when moving, it may encounter obstacles with a little height limit; the height of the shrunk humidifier is reduced At this time, it is more convenient to store and has a lower passing height; when it is necessary to store and encounter high obstacles during the moving process, the control system starts the electric rod 111 to expand and contract, and drives the upper bracket 11 to shrink into the rectangular cavity of the base frame 1 12 inside.

The air intake fan 21 sucks the external air into the device, at this time, the air is used to cool down the components along the air path, and the air flows through the mist generating device along the air duct; it is used in offices, living rooms and other rooms with large spaces and many people. When using an ultrasonic wetting device; the ultrasonic unit utilizes the vibrating element 31 to vibrate the water through high-frequency vibrations, and shatters it into 4-6 nanometer water droplets, and makes the water droplets fall into the air-inducing plate 32 through the filter screen at the bottom of itself; The air inhaled by the fan rises to the ion reaction device together; when used in bedrooms, elderly rooms and baby rooms where the space is small and needs to be quiet and safe, the evaporative humidification device is used. At this time, the evaporation box 33 is used, and the internal installation There is an evaporating plate 331; the evaporating plate 331 is a cylindrical structure, and the side wall of the evaporating plate 331 is fixed with a sponge; the water attached to the inside of the sponge is driven to evaporate by the airflow flowing through the evaporating plate 331, and is lifted to the ion reaction device by the airflow place.

At this time, the rising air and water vapor pass through the ion reaction device, and use the ion reaction characteristics to remove the water vapor and the germs inside the air, that is, the germs passing through the device will be punctured by the ion nucleus, destroying the protein structure of the germs and making them inactive; at this time The treated mixed moisture passes through the air duct 23 and rotates along the protrusion on the inner wall. At this time, the air changes into a spiral air flow; and because the air duct 23 is made of rubber, it can Transform and restore.

At this time, the air flow needs to pass through the air deflector 241 through the suction force of the exhaust fan; This drives the driven gear 242 to rotate, and the driven gear 242 drives the wind deflector 241 to swing around the central axis of the driven gear 242, and the airflow passing through the wind deflector 241 changes the direction of the wind and is discharged into the indoor air under the influence of the orientation of the wind deflector 241 , to complete a humidification and purification cycle.
