Detailed ways

See attached picture. The utility model comprises a hollow glass sphere 2 with an opening at the bottom, a lower bottom 15 is provided at the opening, a spacer 3 and an interlayer 10 are arranged in the lower bottom 15 from top to bottom, and a spacer 3 and an interlayer 10 are arranged on the spacer 3. Air vent 4, the bottom of the air vent 4 is provided with an ultrasonic atomization sheet 6, and a cotton core 7 is connected below the ultrasonic atomization sheet 6, and after the cotton core 7 passes through the circular hole 11 on the interlayer 10, it is connected with the The water storage balloon 13 located under the interlayer 10 is connected; the spacer 3 and the interlayer 10 are provided with a ring-shaped black light 8, and the inner side of the hollow glass ball 2 is coated with an ultraviolet color-developing ink printing layer; the ultrasonic fog The chip 6 and the ring black light 8 are connected to the control circuit 9 , and the control circuit 9 is connected to the humidity sensor 14 .

The control circuit 9 includes a rectification circuit and a logic circuit. The rectification circuit can convert the 220v mains power into a low-voltage direct current to supply power to the logic circuit. After the humidity sensor 14 detects that the humidity in the air exceeds the preset value , supplying power to the ultrasonic atomizing sheet 6, the ultrasonic atomizing sheet 6 atomizes the water on the cotton core 7 into water mist and then enters the hollow glass ball 2, forming a water mist effect on the hollow glass ball 2; the logic circuit passes through the humidity sensor 14 After detecting that the humidity in the air is lower than the over-dry preset value, control the mains to supply power to the ring-shaped black light lamp 8, and the ultraviolet color-developing ink printing layer on the hollow glass bulb 2 develops color, thereby forming a dry cracking effect on the hollow glass bulb 2.

The hollow glass sphere 2 and the interlayer 10 are a closed structure, and the moisture will not be lost therein. When the ultrasonic atomizing sheet 6 is not working, the moisture will naturally flow back into the water storage balloon 13 under the action of gravity. The water storage balloon 13 has certain elasticity to make the cotton core 7 closely contact with the ultrasonic atomizing sheet 6 .

The interlayer 10 and the lower bottom 15 form a closed space. The water vapor generated by the ultrasonic atomizing sheet 6 will not affect the detection of the surrounding environment by the humidity sensor 14 .

The utility model is also provided with a belt 1, and the two sides of the lower bottom 15 are provided with T-shaped holes 16 matched with the belt 1. During use, the T-shaped holes 16 on both sides of the bottom 15 can be fastened with the belt 1, and hung on the wall for decoration and use.

The utility model is also provided with a circular base 5, the lower bottom 15 is arranged in the circular base 5, and the outline of the circular base 5 coincides with the outline of the semi-closed hollow glass ball 2.

The interlayer 10 is provided with a wire channel 12 , and the lower bottom 15 is provided with a ventilation hole 17 and a sliding switch 18 for controlling the opening and closing of the ventilation hole 17 . The humidity sensor 14 exchanges air with the outside world through the ventilation hole 17 on the bottom 15 .

The upper end of the cotton core 7 withstands the ultrasonic atomizing sheet 6 for water supply, and the lower end passes through the round hole 11 of the interlayer 10 and penetrates into the water storage balloon 13 .

When the utility model is in use, after the sliding switch 18 is slid to the open state, the humidity sensor 14 detects the humidity of the surrounding environment, and when the humidity is higher than the set overhumidity preset value, the control circuit 9 controls and starts the ultrasonic atomizing sheet 6 , water vapor is generated, and the water vapor diverges from the vent hole 4 on the spacer 3, and gradually forms water mist on the inner side of the hollow glass ball 2, presenting a wet visual effect; when the user takes corresponding measures to reduce the humidity in the environment, the humidity is at When the value is normal, the control circuit 9 cuts off the power supply of the ultrasonic atomizing sheet 6, and the water vapor on the inner wall of the hollow glass ball 2 will gradually gather into large water droplets, which will flow back to the storage tank under the guidance of the arc of the hollow glass ball 2 and the interlayer 10. In the water balloon 13, the spheroid recovers the transparent state. When it is detected that the humidity is lower than the set over-dry preset value, the ring-shaped black light lamp 8 is activated by the control circuit 9, and the ultraviolet rays pass through the gap between the spacer 3 and the lower bottom 15 and irradiate the hollow glass bulb 2 to print with ultraviolet color developing ink. The cracked pattern of the layer makes it change from colorless to colored, and a cracked pattern appears, showing the visual effect of cracked. When the user takes corresponding measures to increase the ambient humidity and the humidity is at a normal value, the control circuit 9 cuts off the power supply of the ring-shaped black light lamp 8, and the sphere returns to a transparent state.

The utility model reflects the humidity state in the current air through the intuitive visual effects of dampness, dryness and transparency in the hollow glass sphere, and the humidity in the existing air is easy to be understood by people through dampness, dryness and transparency. The air humidity information is used to remind and help users have a healthy and comfortable living environment.
